과학기술(科學技術)의 발전(發展)에 따른 생활(生活) 및 의료(醫療) 수준의 향상(向上)에도 불구하고 산업발전(産業發展)에 따른 환경오염(環境汚染), 스트레스 증가(增加) 등 그 역기능(逆機能) 때문에 발암물질(發癌物質) 또는 자극(刺戟)에의 노출(露出) 등으로 인해서 전세계적(全世界的)으로 암(癌)으로 인(因)한 사망율(死亡率)이 증가(增加)되고 있다. 암(癌)은 현재(現在) 인류(人類)의 건강(健康)을 위협하는 주요(主要)한 질환(疾患)의 하나로, 오늘날 우리 나라에서 질환(疾患)으로 인(因)한 사망원인중(死亡原因中) 수위(首位)를 차지하고 있다. 이러한 암(癌)의 발생(發生)은 80%-90%가 환경적(環境的) 인자(因子)에 기인(起因)한다고 보고(報告)되고 있는데 앞으로 환경성(環境性) 발암물질(發癌物質)이 점차 증가(增加)됨에 따라 암환자(癌患者)의 발생(發生)도 더욱 증가(增加)될 것으로 예상(豫想)된다. 암(癌)의 서의학적(西醫學的) 치료(治療)는 주로 수술요법(手術療法), 방사선요법(放射線療法), 화학요법(化學療法) 및 면역요법(免疫療法) 등이 활용(活用)되고 있다. 이중 수술요법(手術療法)과 방사선요법(放射線療法)은 암(癌)이 전신(全身)에 전이(轉移) 증식(增殖)되기 전에 실시(實施)함으로써 효과(效果)를 거둘 수는 있으나, 암(癌)이 원발병소(原發病巢) 이외(以外)에까지 전이(轉移) 증식(增殖)되었을 경우에는 이 두가지 방법(方法)의 국소요법(局所療法)만으로서는 좋은 치료효과(治療效果)를 거두기 어렵다. 따라서 최근 항암제(抗癌劑)에 의한 화학요법(化學療法)이 다른 방법(方法)보다 유효(有效)하다고 인정(認定)이 되어 가장 많이 활용(活用)되고 있으나, 암종(癌種)에 대한 감수성차이(感受性差異), 치료후(治療後)의 부작용(副作用), 재발(再發) 및 합병증(合倂症) 등의 문제점(問題點)때문에 부작용(副作用)을 감소(減少)시키면서 항암효과(抗癌效果)를 높이는 치료법(治療法)이 계속 연구(硏究)되고 있다. 이에 1972년(年) 미국(美國) 국립암연구소(國立癌硏究所)에서 실시(實施)한 항암제(抗癌劑) 개발연구(開發硏究)에 있어서 항종양성(抗腫瘍性) Screening test에 이용(利用)된 물질중(物質中) 약 47%가 천연물질(天然物質)이었다는 사실은 주목(注目)할만 하다. 한의학적(韓醫學的) 치료법(治療法)은 최근(最近)에 변증시치(辨證施治)를 근간(根幹)으로 하여 건비익기(健脾益氣)를 위주(爲主)로한 부정거사법(扶正祛邪法)과 부정배본법(扶正培本法)이 많이 활용(活用)되고 있으며 부정법(扶正法)으로는 익기건비(益氣健脾), 자음보혈(滋陰補血), 온보비신(溫補裨腎) 등이, 거사법(祛邪法)으로는 활혈거어법(活血祛瘀法), 청열해독법(淸熱解毒法), 연견화담법(軟堅化痰法) 등이 활용(活用)되고 있는데, 이를 근거(根據)로 하여 한약(韓藥)의 복방(複方).단미(單味).단미추출물(單味抽出物) 등의 투여(投與)와 침(鍼) 구(灸) 수침(水鍼) 전침(電鍼) laser침(鍼)등의 치료방법(治療方法)을 수술(手術) 후(後) 혹(或)은 화학요법(化學療法)이나 방사선요법(放射線療法)와 병행(幷行)하여 치료효과(治療效果)가 향상(向上)되었다고 보고(報告)하고 있다. 항암제(抗癌劑)의 항암효과(抗癌效果) 정도(程度)를 검사(檢査)하는 방법(方法)은 크게 5가지로 분류(分類)되는데, 하나는 세포(細胞)를 약제(藥劑)에 노출(露出)시킨 후 현미경(顯微鏡)을 통하여 나타난 형태학적(形態學的) 변화(變化)를 가지고 약제(藥劑)의 효과정도(效果程度)를 결정(決定)하는 방법(方法)이고, 둘째는 Dye exclusion assay방법(方法)으로 살아있는 세포(細胞)가 trypan blue, eosin, nigrosin과 같은 염색액(染色液)에 염색(染色)되지 않는 점을 이용(利用)한 것이며, 세번째는 항암제(抗癌劑)의 항암효과(抗癌效果)를 알아보는 지표(指標)로 사용(使用)되는 Crrelease assay가 있으나, 세가지 방법(方法) 모두 현재(現在) 사용(使用)되고 있지 않다. 넷째로는 세포(細胞) 대사(代謝)의 방해정도(妨害程度)를 측정(測定)하거나 세포내(細胞內) 방사성(放射性) 동위원소(同位元素)의 유입방해(流入妨害) 정도(程度)를 측정(測定)하는 방법(方法)이 있고, 다섯째로는 본(本) 실험(實驗)에서 사용(使用)한 방법(方法)으로 stem cell assay라고도 하는 clonogenetic assay가 있는데, 이는 세포(細胞)를 약제(藥劑)에 노출(露出) 시킨 후 soft agar에 single cell suspension으로 배양(培養)하여 그 세포(細胞)의 분열(分裂).증식능력(增殖能力)을 측정(測定)하는 방법(方法)이다. 이 방법(方法)은 특히 성장(成長) 특성(特性)이 다른 종양세포(腫瘍細胞)의 경우 개개(個個) 세포(細胞)에 대한 약제효과(藥劑效果)를 반영(反映)할 수 있어서 종양세포(腫瘍細胞)의 이질성(異質性)에 따른 차이점(差異點)을 보정(補整)할 수 있는 방법(方法)이며, 1971년(年) Park 등이 마우스 골수종(骨髓腫) 세포(細胞)에 대한 stem cell assay를 시행(施行)해 본 결과(結果) in vivo에서의 결과(結果)와 잘 일치(一致)하여 그 이후로는 종양세포(腫瘍細胞)에 대한 항암제(抗癌劑)의 약제(藥劑) 감수성검사(感受性檢査)에 많이 사용(使用)되고 있다. 진령탕가감방은 담습응결(痰濕凝結)을 치료(治療)하는 효능(效能)을 가진 처방(處方)으로 거담작용(祛痰作用)을 가진 반하(半夏), 패모(貝母), 거습작용(祛濕作用)을 가진 의이인(薏苡仁), 백복령, 이기(理氣) 하기작용(下氣作用)을 가진 진피(陳皮), 대자석, 정향(丁香), 비파엽(枇杷葉), 항암작용(抗癌作用)을 가진 용규(龍葵), 반지련(半枝蓮), 모려(牡蠣), 하고초(夏枯草), 저령 등(等)의 약물(藥物)로 구성되어 있다. 근래(近來) 단일약물(單一藥物)의 항암효과(抗癌效果)에 대한 실험적(實驗的) 연구(硏究)로는 금(金) 등에 의한 인삼(人蔘), 녹용(鹿茸)의 항체생산(抗體生産) 억제(抑制) 완화효과(緩和效果) 및 임(任)에 의한 어성초(魚腥草), 녹혈(鹿血), 저령, 천산갑(穿山甲) 등이 정상(正常) 면역세포(免役細胞)에는 거의 독작용(毒作用)을 일으키지 않으면서 강력(强力)한 항암효과(抗癌效果)가 있다는 보고(報告), 금(金) 등에 의한 자완, 동풍채(東風菜), 영지(靈芝), 선학초(仙鶴草), 파두(巴豆) 등이 항암작용(抗癌作用) 및 면역반응(免疫反應)에 효과(效果)를 미친다는 보고(報告) 등이 있고, 복합제제(複合製劑) 약물(藥物)의 항암효과(抗癌效果)에 대한 연구(硏究)로는 강(姜) 등에 의한 식분환(息賁丸), 비기환(肥氣丸) 및 비기환이 백혈병(白血病)과 임파종환자(淋巴腫患者)에서 추출(抽出)한 암세포(癌細胞)에 항암효과(抗癌效果)가 있다는 보고(報告) 및 금(金) 등에 의한 복량환(伏梁丸), 비기환 및 소적정원산(消積正元散)이 각종(各種) 암세포주(癌細胞柱)이 성장저애(成長沮碍) 효과(效果), 윤(尹) 등에 의한 육군자탕(六君子湯), 소시호탕(小柴胡湯), 사묘탕(四妙湯), 대시호탕(大柴胡湯), 방독탕(防毒湯), 반하백출천마탕(半夏白朮天麻湯), 파두(巴豆)를 가미(加味)한 사군자탕(四君子湯) 및 사물탕(四物湯) 등이 항암작용(抗癌作用) 및 면역반응(免疫反應)에 효과(效果)를 보인다는 보고(報告) 등이 있었으나, 아직까지 진령탕가감방의 항암효과(抗癌效果)에 대한 실험연구(實驗硏究)는 없었다. 이에 저자(著者)는 항암효과(抗癌效果)가 있을 것으로 추정(推定)되는 진령탕가감방의 항종양효과(抗種瘍效果)를 알아보기 위하여, 수용성(水溶性) 추출액(抽出液)을 얻은 후 현대(現代) 병리학적(病理學的)으로 다용(多用)하는 colony형성억제실험(形成抑制實驗), SRB assay에 의한 항종양효과(抗種瘍效果), 생명연장율(生命延長率), 화학적(化學的)인 방법(方法)과 암종세포(癌腫細胞) 이식(移植)에 의한 종양(腫瘍) 유발(誘發)을 통하여 암(癌) 발생(發生) 및 그 경과(經過)에 미치는 영향(影響) 및 NK세포활성(細胞活性)에 미치는 영향(影響) 등을 관찰(觀察)하였다. 본(本) 실험(實驗)에서는 진령탕가감방의 종양세포(腫瘍細胞)에 대한 증식억제작용(增殖抑制作用)을 관찰(觀察)하고자 in vitro test인 colony형성억제실험(形成抑制實驗)과 SRB assay를 이용(利用)하였는데, 진령탕가감방의 추출액(抽出液)이 종양세포(腫瘍細胞)의 성장(成長)을 억제(抑制)하는 효과(效果)가 농도의존적(濃度依存的)으로 증가(增加)하는 결과(結果)를 보여 항종양(抗腫瘍)의 효과(效果)가 있음을 나타냈고(Table 3, 4), in vivo assay로서 sarcoma 180 복수암세포를 이식(移植)한 마우스의 평균생존일수(平均生存日數)를 관찰(觀察)하여 NCI protocol에 의하여 검정(檢定)한 결과(結果), 진령탕가감방 추출액(抽出液)을 투여(投與)한 마우스의 평균생존기간(平均生存期間) 및 생명연장율(生命延長率)이 뚜렷하게 증가(增加)되었다(Table 5). 또한 진령탕가감방 추출액(抽出液)을 마우스에 투여(投與)하면 MCA로 유도(誘導)한 종양(腫瘍) 및 3LL 세포(細胞) 이식(移植)에 의한 종양(腫瘍)의 발생율(發生率) 및 발생(發生)된 종양(腫瘍)의 크기가 현저히 감소(減少)되었다(Table 6, 7). 이러한 효과(效果)는 진령탕가감방이 감수성(感受性) 암종세포(癌腫細胞)에 직접적으로 영향(影響)을 미쳐 그 증식(增殖)이 억제(抑制)되었을 가능성(可能性)을 생각할 수 있다. 그렇지만 본(本) 연구(硏究)에서는 암종특이성(癌腫特異性)에 관한 결론(結論)을 내릴 수는 없으므로 암종특이성(癌腫特異性)에 관한 연구(硏究)는 진행(進行)해야 할 것으로 생각된다. 또 다른 가능(可能)한 진령탕가감방 추출액(抽出液)의 항종양(抗腫瘍) 작용기전(作用機轉)은 진령탕가감방 추출액(抽出液)이 NK세포(細胞)의 활성(活性)을 항진(亢進)시킨 실험결과(實驗結果)로 유추(類推)하여, 진령탕가감방 추출액(抽出液)이 종양(腫瘍)마우스에 비특이적(非特異的)인 면역활성(免疫活性)을 촉진(促進)시킴으로써 진령탕가감방 추출액(抽出液)의 항종양작용(抗腫瘍作用)이 발현될 가능성(可能性)도 생각할 수 있다. 따라서 앞으로 여러 암종세포(癌腫細胞)에 대한 진령탕가감방 추출액(抽出液)의 항종양작용(抗腫瘍作用)과 종양동물(腫瘍動物)에서의 진령탕가감방 추출액(抽出液) 투여(投與)에 의한 생체생리현상(生體生理現象)의 변화(變化), 생리활성물질(生理活性物質)의 본능(本能) 등을 밝히기 위한 보다 구체적(具體的)이고 광범위(廣範圍)한 연구(硏究)가 수행(隨行)되어져야 되리라고 사료(思料)된다. 세포성(細胞性) 면역반응중(免疫反應中) 중요(重要)한 역할(役割)을 하는 작동세포중 NK세포(細胞)는 여러 종양(腫瘍)에 대해 자연살해능(自然殺害能)을 보여 소위 T비의존성(非依存性) 면역감시기전(免疫監視機轉)에 관하여는 바이러스 및 세균(細菌)에 감염(感染)된 세포(細胞)를 파괴(破壞)하는 활성(活性)을 가지며, IL-2 및 Interferon 등에 의하여 활성(活性)이 증가(增加)된다. NK세포(細胞)가 표적세포를 파괴(破壞)하는 기전(機轉)에 관해서는 아직 확실히 알려져 있지 않으나, 첫째로 표적세포를 인식(認識)하는 시기(時期), 둘째로 융해기전(融解機轉)을 활성화(活性化)시키는 시기(時期), 셋째로 NK lymphotoxin이 유리(遊離)되는 시기(時期), 넷째로 표적세포의 사멸기(死滅期)로 나눌 수 있다. 본(本) 실험(實驗)에서 진령탕가감방 추출액(抽出液)으로 전처리(前處理)시 NK세포(細胞)의 표적세포와의 결합능(結合能)은 물론 결합(結合)된 표적세포의 융해능(融解能)이 촉진(促進)된 결과(結果)를 보이는데(Table 8), 이와 같은 결과(結果)는 진령탕가감방 추출액(抽出液)이 NK세포(細胞)의 표적세포 파괴 4단계 전체를 항진(亢進)시킨 결과(結果)로 인정(認定)된다. 이상에서 다음과 같은 결론을 얻었다. 1. 진령탕가감방 추출액(抽出液)을 폐암세포주인 A549와 간암세포주인 hep3B 및 신장암 유래의 종양세포주인 Caki-1 cell에 투여(投與)한 결과, in vitro test인 colony형성억제실험(形成抑制實驗)과 SRB assay에서 모두 농도의존적(濃度依存的)으로 암세포주 성장(成長)을 억제(抑制)하였다. 2. Strcoma 180세포(細胞)를 마우스에 이식(移植)하여 평균생존기간(平均生存期間) 및 생명연장율(生命延長率)을 측정(測定)하는 in vivo test에서는 진령탕가감방 추출액(抽出液)이 마우스의 평균생존기간(平均生存期間) 및 생명연장율(生命延長率)을 증가(增加)시키는 결과(結果)를 보였다. 3. 진령탕가감방 추출액(抽出液)은 MCA로 유도(誘導)한 종양(腫瘍)의 발생율(發生率) 및 발생종양(發生腫瘍)의 크기를 현저히 감소(減少)시켰으며, 3LL세포(細胞) 이식(移植)에 의한 종양발생(腫瘍發生) 또한 현저히 감소(減少)시켰다. 4. 진령탕가감방 추출액(抽出液)은 NK세포(細胞)의 활성도(活性度)를 증가(增加)시켰다. 특히 $10{\mu}g/ml$ 농도 에서 NK세포(細胞) 활성도(活性度)가 가장 현저히 증가(增加)되었다. 이상(以上)의 결과(結果)로 보아 진령탕가감방은 암종세포(癌腫細胞)에 대한 직접적(直接的)인 성장억제(成長抑制) 및 세포(細胞)의 활성(活性)을 통한 면역증진(免疫增進)에 의해 다양(多樣)한 항종양효과(抗腫瘍效果)를 보인 것으로 사료(思料)된다.

This project was a service-cum-research effort with a quasi-experimental study design to examine the health benefits of an integrated Family Planning (FP)/Maternal & Child health (MCH) Service approach that provides crucial factors missing in the present on-going programs. The specific objectives were: 1) To test the effectiveness of trained nurse/midwives (MW) assigned as change agents in the Health Sub-Center (HSC) to bring about the changes in the eight FP/MCH indicators, namely; (i)FP/MCH contacts between field workers and their clients (ii) the use of effective FP methods, (iii) the inter-birth interval and/or open interval, (iv) prenatal care by medically qualified personnel, (v) medically supervised deliveries, (vi) the rate of induced abortion, (vii) maternal and infant morbidity, and (viii) preinatal & infant mortality. 2) To measure the integrative linkage (contacts) between MW & HSC workers and between HSC and clients. 3) To examine the organizational or administrative factors influencing integrative linkage between health workers. Study design; The above objectives called for quasi-experimental design setting up a study and control area with and without a midwife. An active intervention program (FP/MCH minimum 'package' program) was conducted for a 2 year period from June 1982-July 1984 in Seosan County and 'before and after' surveys were conducted to measure the change. Service input; This study was undertaken by the Soonchunhyang University in collaboration with WHO. After a baseline survery in 1981, trained nurses/midwives were introduced into two health sub-centers in a rural setting (Seosan county) for a 2 year period from 1982 to 1984. A major service input was the establishment of midwifery services in the existing health delivery system with emphasis on nurse/midwife's role as the link between health workers (nurse aids) and village health workers, and the referral of risk patients to the private physician (OBGY specialist). An evaluation survey was made in August 1984 to assess the effectiveness of this alternative integrated approach in the study areas in comparison with the control area which had normal government services. Method of evaluation; a. In this study, the primary objective was first to examine to what extent the FP/MCH package program brought about changes in the pre-determined eight indicators (outcome and impact measures) and the following relationship was first analyzed; b. Nevertheless, this project did not automatically accept the assumption that if two or more activities were integrated, the results would automatically be better than a non-integrated or categorical program. There is a need to assess the 'integration process' itself within the package program. The process of integration was measured in terms of interactive linkages, or the quantity & quality of contacts between workers & clients and among workers. Intergrative linkages were hypothesized to be influenced by organizational factors at the HSC clinic level including HSC goals, sltrurture, authority, leadership style, resources, and personal characteristics of HSC staff. The extent or degree of integration, as measured by the intensity of integrative linkages, was in turn presumed to influence programme performance. Thus as indicated diagrammatically below, organizational factors constituted the independent variables, integration as the intervening variable and programme performance with respect to family planning and health services as the dependent variable: Concerning organizational factors, however, due to the limited number of HSCs (2 in the study area and 3 in the control area), they were studied by participatory observation of an anthropologist who was independent of the project. In this observation, we examined whether the assumed integration process actually occurred or not. If not, what were the constraints in producing an effective integration process. Summary of Findings; A) Program effects and impact 1. Effects on FP use: During this 2 year action period, FP acceptance increased from 58% in 1981 to 78% in 1984 in both the study and control areas. This increase in both areas was mainly due to the new family planning campaign driven by the Government for the same study period. Therefore, there was no increment of FP acceptance rate due to additional input of MW to the on-going FP program. But in the study area, quality aspects of FP were somewhat improved, having a better continuation rate of IUDs & pills and more use of effective Contraceptive methods in comparison with the control area. 2. Effects of use of MCH services: Between the study and control areas, however, there was a significant difference in maternal and child health care. For example, the coverage of prenatal care was increased from 53% for 1981 birth cohort to 75% for 1984 birth cohort in the study area. In the control area, the same increased from 41% (1981) to 65% (1984). It is noteworthy that almost two thirds of the recent birth cohort received prenatal care even in the control area, indicating that there is a growing demand of MCH care as the size of family norm becomes smaller 3. There has been a substantive increase in delivery care by medical professions in the study area, with an annual increase rate of 10% due to midwives input in the study areas. The project had about two times greater effect on postnatal care (68% vs. 33%) at delivery care(45.2% vs. 26.1%). 4. The study area had better reproductive efficiency (wanted pregancies with FP practice & healthy live births survived by one year old) than the control area, especially among women under 30 (14.1% vs. 9.6%). The proportion of women who preferred the 1st trimester for their first prenatal care rose significantly in the study area as compared to the control area (24% vs 13%). B) Effects on Interactive Linkage 1. This project made a contribution in making several useful steps in the direction of service integration, namely; i) The health workers have become familiar with procedures on how to work together with each other (especially with a midwife) in carrying out their work in FP/MCH and, ii) The health workers have gotten a feeling of the usefulness of family health records (statistical integration) in identifying targets in their own work and their usefulness in caring for family health. 2. On the other hand, because of a lack of required organizational factors, complete linkage was not obtained as the project intended. i) In regards to the government health worker's activities in terms of home visiting there was not much difference between the study & control areas though the MW did more home visiting than Government health workers. ii) In assessing the service performance of MW & health workers, the midwives balanced their workload between 40% FP, 40% MCH & 20% other activities (mainly immunization). However, $85{\sim}90%$ of the services provided by the health workers were other than FP/MCH, mainly for immunizations such as the encephalitis campaign. In the control area, a similar pattern was observed. Over 75% of their service was other than FP/MCH. Therefore, the pattern shows the health workers are a long way from becoming multipurpose workers even though the government is pushing in this direction. 3. Villagers were much more likely to visit the health sub-center clinic in the study area than in the control area (58% vs.31%) and for more combined care (45% vs.23%). C) Organization factors (admistrative integrative issues) 1. When MW (new workers with higher qualification) were introduced to HSC, it was noted that there were conflicts between the existing HSC workers (Nurse aids with less qualification than MW) and the MW for the beginning period of the project. The cause of the conflict was studied by an anthropologist and it was pointed out that these functional integration problems stemmed from the structural inadequacies of the health subcenter organization as indicated below; i) There is still no general consensus about the objectives and goals of the project between the project staff and the existing health workers. ii) There is no formal linkage between the responsibility of each member's job in the health sub-center. iii) There is still little chance for midwives to play a catalytic role or to establish communicative networks between workers in order to link various knowledge and skills to provide better FP/MCH services in the health sub-center. 2. Based on the above findings the project recommended to the County Chief (who has power to control the administrative staff and the technical staff in his county) the following ; i) In order to solve the conflicts between the individual roles and functions in performing health care activities, there must be goals agreed upon by both. ii) The health sub·center must function as an autonomous organization to undertake the integration health project. In order to do that, it is necessary to support administrative considerations, and to establish a communication system for supervision and to control of the health sub-centers. iii) The administrative organization, tentatively, must be organized to bind the health worker's midwive's and director's jobs by an organic relationship in order to achieve the integrative system under the leadership of health sub-center director. After submitting this observation report, there has been better understanding from frequent meetings & communication between HW/MW in FP/MCH work as the program developed. Lessons learned from the Seosan Project (on issues of FP/MCH integration in Korea); 1) A majority or about 80% of the couples are now practicing FP. As indicated by the study, there is a growing demand from clients for the health system to provide more MCH services than FP in order to maintain the achieved small size of family through FP practice. It is fortunate to see that the government is now formulating a MCH policy for the year 2,000 and revising MCH laws and regulations to emphasize more MCH care for achieving a small size family through family planning practice. 2) Goal consensus in FP/MCH shouBd be made among the health workers It administrators, especially to emphasize the need of care of 'wanted' child. But there is a long way to go to realize the 'real' integration of FP into MCH in Korea, unless there is a structural integration FP/MCH because a categorical FP is still first priority to reduce the rate of population growth for economic reasons but not yet for health/welfare reasons in practice. 3) There should be more financial allocation: (i) a midwife should be made available to help to promote the MCH program and coordinate services, (in) there should be a health sub·center director who can provide leadership training for managing the integrated program. There is a need for 'organizational support', if the decision of integration is made to obtain benefit from both FP & MCH. In other words, costs should be paid equally to both FP/MCH. The integration slogan itself, without the commitment of paying such costs, is powerless to advocate it. 4) Need of management training for middle level health personnel is more acute as the Government has already constructed 90 MCH centers attached to the County Health Center but without adequate manpower, facilities, and guidelines for integrating the work of both FP and MCH. 5) The local government still considers these MCH centers only as delivery centers to take care only of those visiting maternity cases. The MCH center should be a center for the managment of all pregnancies occurring in the community and the promotion of FP with a systematic and effective linkage of resources available in the county such as i.e. Village Health Worker, Community Health Practitioner, Health Sub-center Physicians & Health workers, Doctors and Midwives in MCH center, OBGY Specialists in clinics & hospitals as practiced by the Seosan project at primary health care level.

The success of the family planning program in Korea is reflected in the decrease in the growth rate from 3.0% in 1962 to 2.0% in 1971, and in the decrease in the fertility rate from 43/1,000 in 1960 to 29/1,000 in 1970. However, it would be erroneous to attribute these reductions entirely to the family planning program. Other socio-economic factors, such as the increasing age at marriage and the increasing use of induced abortions, definitely had an impact on the lowered growth and fertility rate. Despite the relative success of the program to data in meeting its goals, there is no room for complacency. Meeting the goal of a further reduction in the population growth rate to 1.3% by 1981 is a much more difficult task than any one faced in the past. Not only must fertility be lowered further, but the size of the target population itself will expand tremendously in the late seventies; due to the post-war baby boom of the 1950's reaching reproductive ages. Furthermore, it is doubtful that the age at marriage will continue to rise as in the past or that the incidence of induced abortion will continue to increase. Consequently, future reductions in fertility will be more dependent on the performance of the national family planning program, with less assistance from these non-program factors. This paper will describe various approaches to help to the solution of these current problems. 1. PRACTICE RATE IN FAMILY PLANNING In 1973, the attitude (approval) and knowledge rates were quite high; 94% and 98% respectively. But a large gap exists between that and the actual practice rate, which is only 3695. Two factors must be considered in attempting to close the KAP-gap. The first is to change social norms, which still favor a larger family, increasing the practice rate cannot be done very quickly. The second point to consider is that the family planning program has not yet reached all the eligible women. A 1973 study determineded that a large portion, 3096 in fact, of all eligible women do not want more children, but are not practicing family planning. Thus, future efforts to help close the KAP-gap must focus attention and services on this important large group of potential acceptors. 2. CONTINUATION RATES Dissatisfaction with the loop and pill has resulted in high discontinuation rates. For example, a 1973 survey revealed that within the first six months initial loop acceptance. nearly 50% were dropouts, and that within the first four months of inital pill acceptance. nearly 50% were dropouts. These discontinuation rates have risen over the past few years. The high rate of discontinuance obviously decreases the contraceptive effectiveness. and has resulted in many unwanted births which is directly related to the increase of induced abortions. In the future, the family planning program must emphasize the improved quality of initial and follow-up services. rather than more quantity, in order to insure higher continuation rates and thus more effective contraceptive protection. 3. INDUCED ABORTION As noted earlier. the use of induced abortions has been increase yearly. For example, in 1960, the average number of abortions was 0.6 abortions per women in the 15-44 age range. By 1970. that had increased to 2 abortions per women. In 1966. 13% of all women between 15-44 had experienced at least one abortion. By 1971, that figure jumped to 28%. In 1973 alone, the total number of abortions was 400,000. Besides the ever incre.sing number of induced abortions, another change has that those who use abortions have shifted since 1965 to include- not. only the middle class, but also rural and low-income women. In the future. in response to the demand for abortion services among rural and low-income w~men, the government must provide and support abortion services for these women as a part of the national family planning program. 4. TARGET SYSTIi:M Since 1962, the nationwide target system has been used to set a target for each method, and the target number of acceptors is then apportioned out to various sub-areas according to the number of eligible couples in each area. Because these targets are set without consideration for demographic factors, particular tastes, prejudices, and previous patterns of acceptance in the area, a high discontinuation rate for all methods and a high wastage rate for the oral pill and condom results. In the future. to alleviate these problems of the methodbased target system. an alternative. such as the weighted-credit system, should be adopted on a nation wide basis. In this system. each contraceptive method is. assigned a specific number of points based upon the couple-years of protection (CYP) provided by the method. and no specific targets for each method are given. 5. INCREASE OF STERILIZA.TION TARGET Two special projects. the hospital-based family planning program and the armed forces program, has greatly contributed to the increasing acceptance in female and male sterilization respectively. From January-September 1974, 28,773 sterilizations were performed. During the same time in 1975, 46,894 were performed; a 63% increase. If this trend continues, by the end of 1975. approximately 70,000 sterilizations will have been performed. Sterilization is a much better method than both the loop and pill, in terms of more effective contraceptive protection and the almost zero dropout rate. In the future, the. family planning program should continue to stress the special programs which make more sterilizations possible. In particular, it should seek to add the laparoscope techniques to facilitate female sterilization acceptance rates. 6. INCREASE NUMBER OF PRIVATE ACCEPTORS Among the current family planning users, approximately 1/3 are in the private sector and thus do not- require government subsidy. The number of private acceptors increases with increasing urbanization and economic growth. To speed this process, the government initiated the special hospital based family planning program which is utilized mostly by the private sector. However, in the future, to further hasten the increase of private acceptors, the government should encourage doctors in private practice to provide family planning services, and provide the contraceptive supplies. This way, those do utilize the private medical system will also be able to receive family planning services and pay for it. Another means of increasing the number of private acceptors, IS to greatly expand the commercial outlets for pills and condoms beyond the existing service points of drugstores, hospitals, and health centers. 7. IE&C PROGRAM The current preferred family size is nearly twice as high as needed to achieve a stable poplation. Also, a strong boy preference hinders a small family size as nearly all couples fuel they must have at least one or more sons. The IE&C program must, in the future, strive to emphasize the values of the small family and equality of the sexes. A second problem for the IE&C program to work. with in the: future is the large group of people who approves family planning, want no more children, but do not practice. The IE&C program must work to motivate these people to accept family planning And finally, for those who already practice, an IE&C program in the future must stress continuation of use. The IE&C campaign, to insure highest effectiveness, should be based on a detailed factor analysis of contraceptive discontinuance. In conclusion, Korea faces a serious unfavorable sociodemographic situation- in the future unless the population growth rate can be curtailed. And in the future, the decrease in fertility will depend solely on the family planning program, as the effect of other socio-economic factors has already been maximumally felt. A second serious factor to consider is the increasing number of eligible women due to the 1950's baby boom. Thus, to meet these challenges, the program target must be increased and the program must improve the effectiveness of its current activities and develop new programs.

여포와 난포의 성숙, 배란과 착상, 임신의 유지와 태아의 성장 발달, 분만 및 유선발육과 비유 등 일련의 생식현상에서 있어서 성선자극호르몬과 스테로이드 호르몬의 작용이 중추적인 역할을 한다는 사실은 오래 전부터 알려져왔다. 그러나 이러한 일련의 현상에 고전적인 호르몬 외에도 다수의 성장인자가 관여되고 있음이 최근의 연구 결과 밝혀지고 있다. 생식기관에서 성장인자들은 대부분 autocrine/paracrine mode로 작용하여, 성선자극호르몬과 스테로이드 호르몬의 작용을 매개하거나 이들 호르몬 등과 교호적인 작용(synergy)을 한다. 생식기관 내 insulin-like growth factor(IGF) system은 최근 가장 활발히 연구된 분야 중의 하나로 생식현상의 전반에 걸쳐 중요한 역할을 하고 있음이 밝혀졌다. 본 지면에서는 IGF system에 관한 개괄적인 정보를 소개하고 현재까지 보고된 intrauterine IGF system에 관한 연구를 요약하고자 한다. IGF family는 IGF-I과 IGF-II ligands, 두종류의 IGF receptors(수용체), 그리고 지금까지 발견된 6종류의 IGF-binding proteins(IGFBPs)로 이루어져 있다. IGF-I과 IGF-II는 proinsulin과 상동한 구조를 가진 peptide로서 포도당과 아미노산 운반을 자극하는 등 insulin과 유사한 작용을 한다. 이 외에도 IGFs는 세포분열촉진제(mitogens)로서 여러 형태의 세포에 걸쳐 세포증식을 자극하고, 세포의 분화(differentiation)과 세포기능의 발현에 관여한다. IGFs는 간과 주로 messenchymal cells에서 발현되어 endocrine mode는 물론 autocrine/paracrine mode로 거의 모든 조직에 작용한다. IGF 수용체는 두종류가 알려져 있는데 type I IGF receptor는 tyrosine kinase로서 IGF-I과 IGF-II에 공히 high-affinity를 나타내고, 상기한 대부분의 IGFs의 작용을 매개한다. Type II IGF receptor 혹은 IGF-II/mannose-6-phosphate receptor는 두개의 서로 다른 binding sites를 가지고 있는데 IGF-II binding site는 IGF-II에만 high-affinity를 나타낸다. Type II IGF receptor의 주요 역할은 IGF-II를 lysosomal targeting하여 ligand를 파괴하는데 있다. 체액 속의 IGFs는 대부분 IGFBP에 결합되어 있다. IGFBPs는 IGF의 저장/운반체 혹은 IGF 작용을 조절하는 역할을 하는 것으로 알려져 있으나 개개 IGFBP의 역할에 대해서는 지극히 제한된 정보만이 알려져 있다. IGFBPs의 IGF ligands에의 affinity는 IGF receptors의 IGFs에의 affinity보다 크기 때문에 대부분의 in vitro 상황 하에서 IGFBPs는 IGF 작용을 억제한다. IGFBP에 결합되어 있는 IGF가 어떤 기작에 의해 IGFBP로부터 분리되어 IGF receptor에 도달하는지는 알려지지 않고 있으나, 혈액과 조직액에 들어있는 불특정 IGFBP protease activity는 IGF의 방출과정에서 일역을 하는 것으로 믿어지고 있다. 최근 연구보고에 의하면 특정 in vitro 상황 하에서 IGFBP-1, -3, -5 등은 IGF와 무관한 작용도 있다는 증빙이 있어 IGF system의 또 다른 차원을 예고하고 있다. IGF family members의 mRNAs & proteins는 영장류, 설치류 및 가축의 자궁조직과 수태물(conceptus)에서 발현되어 자궁과 태아의 성장 발달에 중요한 역할을 한다. 자궁조직의 IGF system의 발현은 성선호르몬, 국소 생리조절인자 등에 의해 발현시기와 장소의 특이성이 결정되며, 발현된 IGFs와 IGFBPs는 autocrine/paracrine mode로 자궁조직에 작용하기도 하고, 자궁강에 분비되어 수태물의 성장 발달에 관여한다. 착상을 전후하여 수태물에서도 IGF system이 발현되는데 개개 IGF family member의 발현 시기는 모체로부터 유래된 mRNA의 유무, 수태물 자체의 genetic programming, 모체와의 상호작용 등에 의해 결정되고, IGFs의 작용 부위 역시 시간(생리적 상태)과 장소의 특이성이 있다. 이와같이 conceptus IGF system의 발현이 시간적, 공간적으로 조절되고있다는 사실은 IGFs가 수태물의 성장 발달에 일역을 한다는 가설을 간접적으로 지지해 준다. 자궁조직과 수태물에서 발현된 IGFs는 세포의 증식과 분화, 포도당과 아미노산의 운반과 단백질합성, placental lactogen과 prolactin 등과 같은 유선자극호르몬의 생성을 자극하고 스테로이드 호르몬의 합성에도 관여한다. 태아의 성장 발달에 있어서 IGFs의 역할은 embryo의 IGF-I, IGF-II, 혹은 IGF receptor gene을 homologous recombination technique에 의해 파괴(gene targeting)하여을 때의 결과로써 입증되었다. 생쥐의 IGF and/or IGF-II gene 혹은 IGF receptor gene을 파괴했을 때 출생 전후 모두 성장 발달이 지연되며 출생시 무게는 정상치의 30-60% 수준에 머물고, 특히 type I IGF receptor gene 혹은 IGF-I과 IGF-II genes를 모두 파괴했을 경우에는 출생 후 곧 치사한다. 자궁 내의 IGFBPs는 IGF ligands를 자궁 내에 제한시키거나 IGFs의 receptor binding을 억제하는 negative regulators 역할을 하는 것으로 믿어지고 있다. 그러나 영장류의 자궁에서 IGFBP-I과 같은 특정 IGFBP는 IGFs보다 월등히 많은 양이 발현 분비되고 있는 것으로 추산되고 있으며, 또한 이 단백질은 모체탈락막세포에서 분비되는 주요 단백질 중의 하나라는 점을 감안할 때 IGFBP-I이 IGF과 무관한 작용이 있을 가능성도 배제할 수 없다. 따라서 IGFBPs의 역할 규명은 IGF system을 이해하는데 중요한 부분을 차지하고 있어 향후 이 분야의 연구에 많은 기대와 촛점이 모여지고 있다.

Much has teed changed in the field of hospital administration in the It wake of the rapid development of sciences, techniques ana systematic hospital management. However, we still have a long way to go in organization, in the quality of hospital employees and hospital equipment and facilities, and in financial support in order to achieve proper hospital management. The above factors greatly effect the ability of hospitals to fulfill their obligation in patient care and nursing services. The purpose of this study is to determine the optimal methods of standardization and quality nursing so as to improve present nursing services through investigations and analyses of various problems concerning nursing administration. This study has been undertaken during the six month period from October 1971 to March 1972. The 41 comprehensive hospitals have been selected iron amongst the 139 in the whole country. These have been categorized according-to the specific purposes of their establishment, such as 7 university hospitals, 18 national or public hospitals, 12 religious hospitals and 4 enterprise ones. The following conclusions have been acquired thus far from information obtained through interviews with nursing directors who are in charge of the nursing administration in each hospital, and further investigations concerning the purposes of establishment, the organization, personnel arrangements, working conditions, practices of service, and budgets of the nursing service department. 1. The nursing administration along with its activities in this country has been uncritical1y adopted from that of the developed countries. It is necessary for us to re-establish a new medical and nursing system which is adequate for our social environments through continuous study and research. 2. The survey shows that the 7 university hospitals were chiefly concerned with education, medical care and research; the 18 national or public hospitals with medical care, public health and charity work; the 2 religious hospitals with medical care, charity and missionary works; and the 4 enterprise hospitals with public health, medical care and charity works. In general, the main purposes of the hospitals were those of charity organizations in the pursuit of medical care, education and public benefits. 3. The survey shows that in general hospital facilities rate 64 per cent and medical care 60 per-cent against a 100 per cent optimum basis in accordance with the medical treatment law and approved criteria for training hospitals. In these respects, university hospitals have achieved the highest standards, followed by religious ones, enterprise ones, and national or public ones in that order. 4. The ages of nursing directors range from 30 to 50. The level of education achieved by most of the directors is that of graduation from a nursing technical high school and a three year nursing junior college; a very few have graduated from college or have taken graduate courses. 5. As for the career tenure of nurses in the hospitals: one-third of the nurses, or 38 per cent, have worked less than one year; those in the category of one year to two represent 24 pet cent. This means that a total of 62 per cent of the career nurses have been practicing their profession for less than two years. Career nurses with over 5 years experience number only 16 per cent: therefore the efficiency of nursing services has been rated very low. 6. As for the standard of education of the nurses: 62 per cent of them have taken a three year course of nursing in junior colleges, and 22 per cent in nursing technical high schools. College graduate nurses come up to only 15 per cent; and those with graduate course only 0.4 per cent. This indicates that most of the nurses are front nursing technical high schools and three year nursing junior colleges. Accordingly, it is advisable that nursing services be divided according to their functions, such as professional, technical nurses and nurse's aides. 7. The survey also shows that the purpose of nursing service administration in the hospitals has been regulated in writing in 74 per cent of the hospitals and not regulated in writing in 26 per cent of the hospitals. The general purposes of nursing are as follows: patient care, assistance in medical care and education. The main purpose of these nursing services is to establish proper operational and personnel management which focus on in-service education. 8. The nursing service departments belong to the medical departments in almost 60 per cent of the hospitals. Even though the nursing service department is formally separated, about 24 per cent of the hospitals regard it as a functional unit in the medical department. Only 5 per cent of the hospitals keep the department as a separate one. To the contrary, approximately 12 per cent of the hospitals have not established a nursing service department at all but surbodinate it to the other department. In this respect, it is required that a new hospital organization be made to acknowledge the independent function of the nursing department. In 76 per cent of the hospitals they have advisory committees under the nursing department, such as a dormitory self·regulating committee, an in-service education committee and a nursing procedure and policy committee. 9. Personnel arrangement and working conditions of nurses 1) The ratio of nurses to patients is as follows: In university hospitals, 1 to 2.9 for hospitalized patients and 1 to 4.0 for out-patients; in religious hospitals, 1 to 2.3 for hospitalized patients and 1 to 5.4 for out-patients. Grouped together this indicates that one nurse covers 2.2 hospitalized patients and 4.3 out-patients on a daily basis. The current medical treatment law stipulates that one nurse should care for 2.5 hospitalized patients or 30.0 out-patients. Therefore the statistics indicate that nursing services are being peformed with an insufficient number of nurses to cover out-patients. The current law concerns the minimum number of nurses and disregards the required number of nurses for operation rooms, recovery rooms, delivery rooms, new-born baby rooms, central supply rooms and emergency rooms. Accordingly, tile medical treatment law has been requested to be amended. 2) The ratio of doctors to nurses: In university hospitals, the ratio is 1 to 1.1; in national of public hospitals, 1 to 0.8; in religious hospitals 1 to 0.5; and in private hospitals 1 to 0.7. The average ratio is 1 to 0.8; generally the ideal ratio is 3 to 1. Since the number of doctors working in hospitals has been recently increasing, the nursing services have consequently teen overloaded, sacrificing the services to the patients. 3) The ratio of nurses to clerical staff is 1 to 0.4. However, the ideal ratio is 5 to 1, that is, 1 to 0.2. This means that clerical personnel far outnumber the nursing staff. 4) The ratio of nurses to nurse's-aides; The average 2.5 to 1 indicates that most of the nursing service are delegated to nurse's-aides owing to the shortage of registered nurses. This is the main cause of the deterioration in the quality of nursing services. It is a real problem in the guest for better nursing services that certain hospitals employ a disproportionate number of nurse's-aides in order to meet financial requirements. 5) As for the working conditions, most of hospitals employ a three-shift day with 8 hours of duty each. However, certain hospitals still use two shifts a day. 6) As for the working environment, most of the hospitals lack welfare and hygienic facilities. 7) The salary basis is the highest in the private university hospitals, with enterprise hospitals next and religious hospitals and national or public ones lowest. 8) Method of employment is made through paper screening, and further that the appointment of nurses is conditional upon the favorable opinion of the nursing directors. 9) The unemployment ratio for one year in 1971 averaged 29 per cent. The reasons for unemployment indicate that the highest is because of marriage up to 40 per cent, and next is because of overseas employment. This high unemployment ratio further causes the deterioration of efficiency in nursing services and supplementary activities. The hospital authorities concerned should take this matter into a jeep consideration in order to reduce unemployment. 10) The importance of in-service education is well recognized and established. 1% has been noted that on the-job nurses. training has been most active, with nursing directors taking charge of the orientation programs of newly employed nurses. However, it is most necessary that a comprehensive study be made of instructors, contents and methods of education with a separate section for in-service education. 10. Nursing services'activities 1) Division of services and job descriptions are urgently required. 81 per rent of the hospitals keep written regulations of services in accordance with nursing service manuals. 19 per cent of the hospitals do not keep written regulations. Most of hospitals delegate to the nursing directors or certain supervisors the power of stipulating service regulations. In 21 per cent of the total hospitals they have policy committees, standardization committees and advisory committees to proceed with the stipulation of regulations. 2) Approximately 81 per cent of the hospitals have service channels in which directors, supervisors, head nurses and staff nurses perform their appropriate services according to the service plans and make up the service reports. In approximately 19 per cent of the hospitals the staff perform their nursing services without utilizing the above channels. 3) In the performance of nursing services, a ward manual is considered the most important one to be utilized in about 32 percent of hospitals. 25 per cent of hospitals indicate they use a kardex; 17 per cent use ward-rounding, and others take advantage of work sheets or coordination with other departments through conferences. 4) In about 78 per cent of hospitals they have records which indicate the status of personnel, and in 22 per cent they have not. 5) It has been advised that morale among nurses may be increased, ensuring more efficient services, by their being able to exchange opinions and views with each other. 6) The satisfactory performance of nursing services rely on the following factors to the degree indicated: approximately 32 per cent to the systematic nursing activities and services; 27 per cent to the head nurses ability for nursing diagnosis; 22 per cent to an effective supervisory system; 16 per cent to the hospital facilities and proper supply, and 3 per cent to effective in·service education. This means that nurses, supervisors, head nurses and directors play the most important roles in the performance of nursing services. 11. About 87 per cent of the hospitals do not have separate budgets for their nursing departments, and only 13 per cent of the hospitals have separate budgets. It is recommended that the planning and execution of the nursing administration be delegated to the pertinent administrators in order to bring about improved proved performances and activities in nursing services.

Just before the Korean War, the total number of the North Korean troops was 198,380, while that of the ROK(Republic of Korea) army troops 105,752. That is, the total number of the ROK army troops at that time was 53.3% of the total number of the North Korean army. As of December 2008, the total number of the North Korean troops is estimated to be 1,190,000, while that of the ROK troops is 655,000, so the ROK army maintains 55.04% of the total number of the North Korean troops. If the ROK army continues to reduce its troops according to [Military Reform Plan 2020], the total number of its troops will be 517,000 m 2020. If North Korea maintains the current status(l,190,000 troops), the number of the ROK troops will be 43.4% of the North Korean army. In terms of units, just before the Korean War, the number of the ROK army divisions and regiments was 80% and 44.8% of North Korean army. As of December 2008, North Korea maintains 86 divisions and 69 regiments. Compared to the North Korean army, the ROK army maintains 46 Divisions (53.4% of North Korean army) and 15 regiments (21.3% of North Korean army). If the ROK army continue to reduce the military units according to [Military Reform Plan 2020], the number of ROK army divisions will be 28(13 Active Division, 4 Mobilization Divisions and 11 Local Reserve Divisions), while that of the North Korean army will be 86 in 2020. In that case, the number of divisions of the ROK army will be 32.5% of North Korean army. During the Korean war, North Korea suddenly invaded the Republic of Korea and occupied its capital 3 days after the war began. At that time, the ROK army maintained 80% of army divisions, compared to the North Korean army. The lesson to be learned from this is that, if the ROK army is forced to disperse its divisions because of the simultaneous invasion of North Korea and attack of guerrillas in home front areas, the Republic of Korea can be in a serious military danger, even though it maintains 80% of military divisions of North Korea. If the ROK army promotes the plans in [Military Reform Plan 2020], the number of military units of the ROK army will be 32.5% of that of the North Korean army. This ratio is 2.4 times lower than that of the time when the Korean war began, and in this case, 90% of total military power should be placed in the DMZ area. If 90% of military power is placed in the DMZ area, few troops will be left for the defense of home front. In addition, if the ROK army continues to reduce the troops, it can allow North Korea to have asymmetrical superiority in military force and it will eventually exert negative influence on the stability and peace of the Korean peninsular. On the other hand, it should be reminded that, during the Korean War, the Republic of Korea was attacked by North Korea, though it kept 53.3% of troops, compared to North Korea. It should also be reminded that, as of 2008, the ROK army is defending its territory with the troops 55.04% of North Korea. Moreover, the national defense is assisted by 25,120 troops of the US Forces in Korea. In case the total number of the ROK troops falls below 43.4% of the North Korean army, it may cause social unrest about the national security and may lead North Korea's misjudgement. Besides, according to Lanchester strategy, the party with weaker military power (60% compared to the party with stronger military power) has the 4.1% of winning possibility. Therefore, if we consider the fact that the total number of the ROK army troops is 55.04% of that of the North Korean army, the winning possibility of the ROK army is not higher than 4.1%. If the total number of ROK troops is reduced to 43.4% of that of North Korea, the winning possibility will be lower and the military operations will be in critically difficult situation. [Military Reform Plan 2020] rums at the reduction of troops and units of the ground forces under the policy of 'select few'. However, the problem is that the financial support to achieve this goal is not secured. Therefore, the promotion of [Military Reform Plan 2020] may cause the weakening of military defence power in 2020. Some advanced countries such as Japan, UK, Germany, and France have promoted the policy of 'select few'. However, what is to be noted is that the national security situation of those countries is much different from that of Korea. With the collapse of the Soviet Unions and European communist countries, the military threat of those European advanced countries has almost disappeared. In addition, the threats those advanced countries are facing are not wars in national level, but terrorism in international level. To cope with the threats like terrorism, large scaled army trops would not be necessary. So those advanced European countries can promote the policy of 'select few'. In line with this, those European countries put their focuses on the development of military sections that deal with non-military operations and protection from unspecified enemies. That is, those countries are promoting the policy of 'select few', because they found that the policy is suitable for their national security environment. Moreover, since they are pursuing common interest under the European Union(EU) and they can form an allied force under NATO, it is natural that they are pursing the 'select few' policy. At present, NATO maintains the larger number of troops(2,446,000) than Russia(l,027,000) to prepare for the potential threat of Russia. The situation of japan is also much different from that of Korea. As a country composed of islands, its prime military focus is put on the maritime defense. Accordingly, the development of ground force is given secondary focus. The japanese government promotes the policy to develop technology-concentrated small size navy and air-forces, instead of maintaining large-scaled ground force. In addition, because of the 'Peace Constitution' that was enacted just after the end of World War II, japan cannot maintain troops more than 240,000. With the limited number of troops (240,000), japan has no choice but to promote the policy of 'select few'. However, the situation of Korea is much different from the situations of those countries. The Republic of Korea is facing the threat of the North Korean Army that aims at keeping a large-scale military force. In addition, the countries surrounding Korea are also super powers containing strong military forces. Therefore, to cope with the actual threat of present and unspecified threat of future, the importance of maintaining a carefully calculated large-scale military force cannot be denied. Furthermore, when considering the fact that Korea is in a peninsular, the Republic of Korea must take it into consideration the tradition of continental countries' to maintain large-scale military powers. Since the Korean War, the ROK army has developed the technology-force combined military system, maintaining proper number of troops and units and pursuing 'select few' policy at the same time. This has been promoted with the consideration of military situation in the Koran peninsular and the cooperation of ROK-US combined forces. This kind of unique military system that cannot be found in other countries can be said to be an insightful one for the preparation for the actual threat of North Korea and the conflicts between continental countries and maritime countries. In addition, this kind of technology-force combined military system has enabled us to keep peace in Korea. Therefore, it would be desirable to maintain this technology-force combined military system until the reunification of the Korean peninsular. Furthermore, it is to be pointed out that blindly following the 'select few' policy of advanced countries is not a good option, because it is ignoring the military strategic situation of the Korean peninsular. If the Republic of Korea pursues the reduction of troops and units radically without consideration of the threat of North Korea and surrounding countries, it could be a significant strategic mistake. In addition, the ROK army should keep an eye on the fact the European advanced countries and Japan that are not facing direct military threats are spending more defense expenditures than Korea. If the ROK army reduces military power without proper alternatives, it would exert a negative effect on the stable economic development of Korea and peaceful reunification of the Korean peninsular. Therefore, the desirable option would be to focus on the development of quality of forces, maintaining proper size and number of troops and units under the technology-force combined military system. The tableau above shows that the advanced countries like the UK, Germany, Italy, and Austria spend more defense expenditure per person than the Republic of Korea, although they do not face actual military threats, and that they keep achieving better economic progress than the countries that spend less defense expenditure. Therefore, it would be necessary to adopt the merits of the defense systems of those advanced countries. As we have examined, it would be desirable to maintain the current size and number of troops and units, to promote 'select few' policy with increased defense expenditure, and to strengthen the technology-force combined military system. On the basis of firm national security, the Republic of Korea can develop efficient policies for reunification and prosperity, and jump into the status of advanced countries. Therefore, the plans to reduce troops and units in [Military Reform Plan 2020] should be reexamined. If it is difficult for the ROK army to maintain its size of 655,000 troops because of low birth rate, the plans to establish the prompt mobilization force or to adopt drafting system should be considered for the maintenance of proper number of troops and units. From now on, the Republic of Korean government should develop plans to keep peace as well as to prepare unexpected changes in the Korean peninsular. For the achievement of these missions, some options can be considered. The first one is to maintain the same size of military troops and units as North Korea. The second one is to maintain the same level of military power as North Korea in terms of military force index. The third one is to maintain the same level of military power as North Korea, with the combination of the prompt mobilization force and the troops in active service under the system of technology-force combined military system. At present, it would be not possible for the ROK army to maintain such a large-size military force as North Korea (1,190,000 troops and 86 units). So it would be rational to maintain almost the same level of military force as North Korea with the combination of the troops on the active list and the prompt mobilization forces. In other words, with the combination of the troops in active service (60%) and the prompt mobilization force (40%), the ROK army should develop the strategies to harmonize technology and forces. The Korean government should also be prepared for the strategic flexibility of USFK, the possibility of American policy change about the location of foreign army, radical unexpected changes in North Korea, the emergence of potential threat, surrounding countries' demand for Korean force for the maintenance of regional stability, and demand for international cooperation against terrorism. For this, it is necessary to develop new approaches toward the proper number and size of troops and units. For instance, to prepare for radical unexpected political or military changes in North Korea, the Republic of Korea should have plans to protect a large number of refugees, to control arms and people, to maintain social security, and to keep orders in North Korea. From the experiences of other countries, it is estimated that 115,000 to 230,000 troops, plus ten thousands of police are required to stabilize the North Korean society, in the case radical unexpected military or political change happens in North Korea. In addition, if the Republic of Korea should perform the release of hostages, control of mass destruction weapons, and suppress the internal wars in North Korea, it should send 460,000 troops to North Korea. Moreover, if the Republic of Korea wants to stop the attack of North Korea and flow of refugees in DMZ area, at least 600,000 troops would be required. In sum, even if the ROK army maintains 600,000 troops, it may need additional 460,000 troops to prepare for unexpected radical changes in North Korea. For this, it is necessary to establish the prompt mobilization force whose size and number are almost the same as the troops in active service. In case the ROK army keeps 650,000 troops, the proper number of the prompt mobilization force would be 460,000 to 500,000.
