The main purpose of the investigation of an accident caused by aircraft is to be prevented the sudden and casual accidents caused by wilful misconduct and fault from pilots, air traffic controllers, hijack, trouble of engine and machinery of aircraft, turbulence during the bad weather, collision between birds and aircraft, near miss flight by aircrafts etc. It is not the purpose of this activity to apportion blame or liability for offender of aircraft accidents. Accidents to aircraft, especially those involving the general public and their property, are a matter of great concern to the aviation community. The system of international regulation exists to improve safety and minimize, as far as possible, the risk of accidents but when they do occur there is a web of systems and procedures to investigate and respond to them. I would like to trace the general line of regulation from an international source in the Chicago Convention of 1944. Article 26 of the Convention lays down the basic principle for the investigation of the aircraft accident. Where there has been an accident to an aircraft of a contracting state which occurs in the territory of another contracting state and which involves death or serious injury or indicates serious technical defect in the aircraft or air navigation facilities, the state in which the accident occurs must institute an inquiry into the circumstances of the accident. That inquiry will be in accordance, in so far as its law permits, with the procedure which may be recommended from time to time by the International Civil Aviation Organization ICAO). There are very general provisions but they state two essential principles: first, in certain circumstances there must be an investigation, and second, who is to be responsible for undertaking that investigation. The latter is an important point to establish otherwise there could be at least two states claiming jurisdiction on the inquiry. The Chicago Convention also provides that the state where the aircraft is registered is to be given the opportunity to appoint observers to be present at the inquiry and the state holding the inquiry must communicate the report and findings in the matter to that other state. It is worth noting that the Chicago Convention (Article 25) also makes provision for assisting aircraft in distress. Each contracting state undertakes to provide such measures of assistance to aircraft in distress in its territory as it may find practicable and to permit (subject to control by its own authorities) the owner of the aircraft or authorities of the state in which the aircraft is registered, to provide such measures of assistance as may be necessitated by circumstances. Significantly, the undertaking can only be given by contracting state but the duty to provide assistance is not limited to aircraft registered in another contracting state, but presumably any aircraft in distress in the territory of the contracting state. Finally, the Convention envisages further regulations (normally to be produced under the auspices of ICAO). In this case the Convention provides that each contracting state, when undertaking a search for missing aircraft, will collaborate in co-ordinated measures which may be recommended from time to time pursuant to the Convention. Since 1944 further international regulations relating to safety and investigation of accidents have been made, both pursuant to Chicago Convention and, in particular, through the vehicle of the ICAO which has, for example, set up an accident and reporting system. By requiring the reporting of certain accidents and incidents it is building up an information service for the benefit of member states. However, Chicago Convention provides that each contracting state undertakes collaborate in securing the highest practicable degree of uniformity in regulations, standards, procedures and organization in relation to aircraft, personnel, airways and auxiliary services in all matters in which such uniformity will facilitate and improve air navigation. To this end, ICAO is to adopt and amend from time to time, as may be necessary, international standards and recommended practices and procedures dealing with, among other things, aircraft in distress and investigation of accidents. Standards and Recommended Practices for Aircraft Accident Injuries were first adopted by the ICAO Council on 11 April 1951 pursuant to Article 37 of the Chicago Convention on International Civil Aviation and were designated as Annex 13 to the Convention. The Standards Recommended Practices were based on Recommendations of the Accident Investigation Division at its first Session in February 1946 which were further developed at the Second Session of the Division in February 1947. The 2nd Edition (1966), 3rd Edition, (1973), 4th Edition (1976), 5th Edition (1979), 6th Edition (1981), 7th Edition (1988), 8th Edition (1992) of the Annex 13 (Aircraft Accident and Incident Investigation) of the Chicago Convention was amended eight times by the ICAO Council since 1966. Annex 13 sets out in detail the international standards and recommended practices to be adopted by contracting states in dealing with a serious accident to an aircraft of a contracting state occurring in the territory of another contracting state, known as the state of occurrence. It provides, principally, that the state in which the aircraft is registered is to be given the opportunity to appoint an accredited representative to be present at the inquiry conducted by the state in which the serious aircraft accident occurs. Article 26 of the Chicago Convention does not indicate what the accredited representative is to do but Annex 13 amplifies his rights and duties. In particular, the accredited representative participates in the inquiry by visiting the scene of the accident, examining the wreckage, questioning witnesses, having full access to all relevant evidence, receiving copies of all pertinent documents and making submissions in respect of the various elements of the inquiry. The main shortcomings of the present system for aircraft accident investigation are that some contracting sates are not applying Annex 13 within its express terms, although they are contracting states. Further, and much more important in practice, there are many countries which apply the letter of Annex 13 in such a way as to sterilise its spirit. This appears to be due to a number of causes often found in combination. Firstly, the requirements of the local law and of the local procedures are interpreted and applied so as preclude a more efficient investigation under Annex 13 in favour of a legalistic and sterile interpretation of its terms. Sometimes this results from a distrust of the motives of persons and bodies wishing to participate or from commercial or related to matters of liability and bodies. These may be political, commercial or related to matters of liability and insurance. Secondly, there is said to be a conscious desire to conduct the investigation in some contracting states in such a way as to absolve from any possibility of blame the authorities or nationals, whether manufacturers, operators or air traffic controllers, of the country in which the inquiry is held. The EEC has also had an input into accidents and investigations. In particular, a directive was issued in December 1980 encouraging the uniformity of standards within the EEC by means of joint co-operation of accident investigation. The sharing of and assisting with technical facilities and information was considered an important means of achieving these goals. It has since been proposed that a European accident investigation committee should be set up by the EEC (Council Directive 80/1266 of 1 December 1980). After I would like to introduce the summary of the legislation examples and system for aircraft accidents investigation of the United States, the United Kingdom, Canada, Germany, The Netherlands, Sweden, Swiss, New Zealand and Japan, and I am going to mention the present system, regulations and aviation act for the aircraft accident investigation in Korea. Furthermore I would like to point out the shortcomings of the present system and regulations and aviation act for the aircraft accident investigation and then I will suggest my personal opinion on the new and dramatic innovation on the system for aircraft accident investigation in Korea. I propose that it is necessary and desirable for us to make a new legislation or to revise the existing aviation act in order to establish the standing and independent Committee of Aircraft Accident Investigation under the Korean Government.

As a part of the epidemiological studies of clonorchiasis, this study was conducted to evaluate the current endemicity and the natural transition of the Clonorchis infection in Gimhae Gun and delta area a high endemic area in Korea in recent years, prior to the introduction of praziquantel which will eventually influence the status of the prevalence. The data obtained in this study in 1983 were evaluated for natural transition of the infection in comparison with those obtained 16 years ago in 1967 by the author(Kim, 1974). The areas of investigation, villages and schools surveyed, methods and techniques used in this study were the same as in 1967, except for the contents of the questionnaire for raw freshwater fish consumption by the local inhabitants. 1) The prevalence rate of clonorchiasis in the general population of the villages was 48.1% on the average out of a total of 484 persons examined. The average of those of the riverside-delta area was 65.2% and 43.0% in the inland area. Among the schoolchildren, the prevalence rate was 8.2% on the average out of a total of 1,423 examined. By area, the prevalence rate was 10.8% in the riverside delta area and 2.8% in the inland area. By sex, difference in the prevalence was seen only in the inhabitants of the inland area showing 52.4% in the male and 33.5% in the female. 2) In the natural transition of the infection, the prevalence rate among the inhabitants has decreased from 68.8% in 1967 to 48.1% in 1983, and in the schoolchildren from 56.4% in 1967 to 8.2% in 1983. The reduction rate was higher in the riverside-delta area than in the inland area. 3) In the prevalence rate by age, 11.9% was first seen in the 5-9 age group and the rate gradually increased up to 75.0% in the 50-59 age group. By sex, the rate was higher in the male than in the female in the 20-29 age group and over. 4) In the natural transition of the prevalence rate by age, the reduction rate of the infection during the past 16 years was greater in the younger age groups up to the 40-49 age group and reached the same level in the age group 50-59. Reduction was seen again in the age group over 60s. By sex, the reduction rate was greater in the female than in the male in the 20-29 age group and over. By area, the reduction rate was greater in the riverside delta area than in the inland area, particularly in the young age groups. 5) In the intensity of the infection among the cases, the mean egg out-put per mg feces per infected cases(EPmg) in the inhabitants was 6.3. EPmg of those of the river-side-delta area was 15.4 and that of the in-land was 2.8. On the other hand, in the schoolchildren, EPmg was 3.2, and no difference was seen between the two areas, the river-side-delta area and the inland area. 6) In the transition of the intensity of the infection by area, EPmg among the inhabitants inexplically increased from 7.8 in 1967 to 15.4 in 1983. This was probably caused by uneven specimen collection in the process of sampling the population. EPmg of the inhabitants in the inland area and those of the schoolchildren of both riverside delta and inland areas showed a similar decrease in the past 16 years. 7) The intensity of the infection by age showed a relatively low level in the 20-29 age group and below, and EPmg 5.1-9.5 was seen in the 30-39 age group and over. Sex, Epmg was 5.8 in the male and 4.7 the female. By in 8) In the transition of the intensity of the infection, EPmg decreased from 6.2 in 1967 to 5.4 in 1983. By age, in contrast to the figures of 1967 in which EPmg gradually increased with some fluctuation from 1.1 in the 0-4 age group to peak 10.5 in the 50-59 age group, in 1983 lower intensity of the infection was seen in the age group from 10-14 to 20-29 with the EPmg range of 0.6-2.7. 9) In the distribution of the clonorchiasis cases by the range of EPmg value, 43.2% of the cases were in 0.1 0.9 and 34.6% in 1.0-4.9. As a whole by cumulative percent, 44.6% of them were under 0.9 as light infection and 86.1% of them under 9.9 up to moderate infection. By sex, no difference was seen in Epmg. 10) In the transition of the distribution by the range of Epmg, the cases were distributed up to the range 80.0-99.9 in 1967 and to 60.0-79.9 in 1983. By cumulative percent, in the range of 0.1-0.9 and less, light infection, 34.3% of them were distributed in 1967 and 44.6% in 1983 with about 10% increase. In the range of 5.0-9.9 and less, up to moderate infection, 83.2% in 1967 and 86.1% in 1983 of the cases were seen, respectively. 11) The practice of raw freshwater fish consumption among the inhabitants seems to have decreased in recent years. Those who admitted to raw freshwater fish consumption in the last two years among the infected inhabitants were 59.3%, although 86.8% of them professed to have experience with raw freshwater fish consumption. 31.7% of those who have had experience of the raw freshwater fish consumption denied any further consumption in recent years. From an interview of 543 school-children, 24.1% of them admitted to an experience of raw freshwater fish consumption. However, those who have practised in the past two years comprized 17.9%. Those who denied raw freshwater fish consumption in recent years among those who had such experience were 26.0% out of 131 interviewed. The rate of raw freshwater fish consumption in both inhabitants and schoolchildren were higher in the male than in the female. On the contrary, the rate of those who did not practise in recent years among those who had experience of raw freshwater fish consumption was higher in the female than in the male. 12) The major reason for the reduction of raw freshwater fish consumption among the local inhabitants was the risk of the fluke infection. However, it has become apparent that such change of taste has resulted from water pollution impact which has affected throughout the areas of the freshwater systems in this locality since last several years. 13) In animal survey, Clonorchis infection was seen in 14.8% of 88 dogs examined and 3.7% of 27 house rats examined. It was noted that populations of dogs and cats have increased in the villages surveyed. Although the prevalence rate was lower in the present survey than those of 1967, the significance of the animals as the reservoir host has not changed. 14) Prevalence rate of Clonorchis infection by cercariae in the first intermediate host, Parafossarulus manchouricus, was 0.6% out of 517 snails examined. The infection rate was lower in comparison with 2.3% out of 2,124 examined in 1967. Moreover, sharp decreases in number and distribution of the intermediate host snails in many watershed areas of the huge freshwater systems in this locality seemed to reduce transmission of Clonorchis in connection with the intermediate host stage of its life cycle. 15) Clonorchis infection in the second intermediate fish hosts was relatively low. The mean number of Clonorchis metacercaria per fish in Pseudorasbora parva was 517 in 1983, whereas it was 1943 in 1968 through 1969. Environmental water pollution has also caused the decreased fish population density in these areas, and this has also apparently affected to the practice of raw freshwater fish consumption among the local inhabitants. 16) In conclusion, endemicity of Clonorchis infection in Gimhae Gum and delta area of the Nagdong River has sharply decreased during the past 16 years. The major cause of the regressive transition of the infection was the water pollution of the land water systems of this locality. The pollution has upset the ecosystems comprizing of the intermediate hosts of Clonorchis in many areas, and also affected to a significant extent to the discontinuance of the local inhabitants for raw freshwater fish consumption.

목 적: 위장관 증세 위주로 발현하는 우유 알레르기(cow's milk allergy with predominantly gastrointestinal symptoms, CMA-GI)는 유발시험 후 유해반응의 발현시간이 즉각적이지 않아 병력청취를 통하여 우유와 발현 증상의 관련성을 의심하기가 쉽지 않다. 또한, 가벼운 구토, 설사 증상부터 괴사성 장염의 발병처럼 높은 사망률을 보이는 경우까지 임상적 스팩트럼이 다양하며, 감염성 질환 등 타 질환과의 철저한 감별진단이 요구되나 어려운 경우가 많다. 저자들은 CMA-GI를 3가지 임상유형으로 분류하여 진단적 효용성을 높이고, 효율적인 치료계획 수립에 도움을 주고자 본 연구를 시행하였다. 대상 및 방법: 1995년 3월부터 1997년 6월까지 대구효성가톨릭대학병원 소아과에 급, 만성 설사 등 위장관 증세를 주소로 내원하여 우유제거 및 유발시험의 반응을 근거로 CMA-GI로 진단된 30명(남 22명, 여 8명)의 영유아를 대상으로 우유 유발시험에 따른 유해반응의 발현시기 및 양상에 따라 3가지 임상 유형으로 분류하고, 입원당시 임상소견, 유해반응의 양상, 면역학적 검사소견, 소장 생검조직의 형태학적 분석 등을 이용하여 각 유형을 비교 관찰하였다. Quick (Q)형은 우유 유발시험 후 1시간 이내에 두드러기형 발진 등이 발현한 경우로, Slow (S)형은 유해반응이 1시간에서 24시간사이에 발현한 경우로, Quick & Slow (Q&S)형은 Q형과 S형의 증상이 함께 나타나는 경우로 분류하였다. 결 과: 1) 대상환아 30명 중 Q형 5례, S형 20례, Q&S형 5례로, S형의 환아가 가장 많았다. 2) 입원당시 연령은 Q형 $81.4{\pm}67.1$일, S형 $31.9{\pm}12.7$일, Q&S형 $366.0{\pm}65.0$일로 각 유형에 따라 호발 연령의 차이를 보였다(p<0.05). 입원당시 체중은 Q형 10~50백분위수, S형 10백분위수 이하, Q&S형 10~25백분위수로 S형과 다른 유형간에 차이를 보였으며(p<0.05), S형 환아 중 90%에서 3백 분위수 이하로 관찰되었다. 3) 입원당시 말초혈액검사상 백혈구수는 Q형 $5,700{\sim}12,300/mm^3$, S형 $10,000{\sim}33,400/mm^3$, Q&S형 $5,200{\sim}14,900/mm^3$로 S형과 다른 유형간에 차이를 보였다(p<0.05). 입원당시 혈중 알부민치는 Q형 $4.2{\pm}0.4\;g/dl$, S형 $3.0{\pm}0.3\;g/dl$, Q&S형 $4.0{\pm}0.3\;g/dl$로 S형과 다른 유형간에 차이를 보였으며(p<0.05), S형 환아 중 85%에서 혈중 알부민치가 3.5 g/dl 이하였다. 4) 소장 조직생검의 형태학적 분석에서 융모의 높이는 Q형, Q&S형은 정상 대조군과 유의한 차이를 보이지 않았으나, S형에서는 의미있는 감소를 보였으며(p<0.05), 45%에서 아전 융모위축(subtotal villous atrophy), 55%에서 부분(partial) 융모위축의 소견이 보여 전례에서 장병증(enteropathy) 소견이 관찰되었다. 5) 추적 관찰 중 타 음식물에 대한 알레르기의 발현은 S형의 환아군에서는 환아의 연령, 전신 상태의 불안정과 위험성 등 윤리적 측면을 고려하여 유발시험을 시행하지 않았으며, Q형에서도 환아의 연령을 고려하여 다양한 유발시험은 제한하였으나, 대개 우유, 대두유, 이유식 분유, 계란 등 1~2가지의 음식물에 유해 반응을 보이는 것으로 관찰되었다. Q&S형군에서는 연령에 따른 이유 식이의 필요성에 따라 다양한 유발시험을 시행하였으며, 계란, 감자, 새우 등 해산물, 두부, 사과, 당근, 쇠고기, 닭고기 등 환자에 따라 다양한 음식물에 유해반응을 보이는 것으로 관찰되었다. 6) 입원당시 혈중 IgE치, 호산구수, 우유단백 RAST치, 콩단백 RAST치, 피부반응검사는 유형간에 차이를 보이지 않았다. 결 론: 위장관 증세 위주로 발현하는 우유 알레르기는 유발 시험에 따른 유해 반응의 발현 시기 및 양상에 따라 3가지 유형으로 분류될 수 있으며, 이들의 임상소견, 소장생검조직 소견, 면역학적 검사 소견, 타 음식물에 대한 알레르기 발현 유무 등에서 각 유형별로 특징적인 임상 양상을 관찰할 수 있으며, 이들 소견을 비교, 분석하여 감별 진단하는 것이 CMA-GI의 진단 및 치료적 접근에서 효용성이 높을 것으로 판단된다.

목적: 아교모세포종의 방사선치료에서 국소제어율과 생존율을 향상시켜 보고자 3차원 입체조형치료기법을 이용한 방사선선량 증가 연구를 전향적으로 시행하였다. 대상 및 방법: 1997년 1월부터 2002년 7월까지 아교모세포종으로 조직학적 진단이 되고 전신수행도(KPS)가 60 이상으로 수술 후 방사선치료를 받은 환자를 대상으로 하였다. 프로토콜에 따라 전향적으로 연구에 참여한 42예의 고선량군과 후향적 대조군인 33예의 저선량군을 비교 분석하였다 고선량군은 3차원 입체조형치료법에 의해 $63.0\~70.2$ Gy (중앙값 66 Gy)의 고선량 방사선을 조사받았으며, 저선량군은 2차원 치료방식으로 현재 표준선량으로 여겨지고 있는 59.4 Gy 정도(최소선량 50.4 Gy, 중앙선량 59.4 Gy)의 계획된 방사선치료를 종료할 수 있었던 환자들을 대상으로 하였다. 수술절제범위에 따라 나누어보면 전절제술 30예($40\%$), 준전절제술 30예($40\%$), 부분절제술 8예($11\%$), 그리고 조직생검만 시행된 환자가 7예($9\%$)였다. 각 환자의 육안종양체적은 CT 혹은 MRI상 수술절제연 및 잔류종양에 의해 정의되었다. 종양주변 부종은 저선량군에서는 임상표적체적에 포함되었지만, 고선량군에서는 재발양상 및 선량증가에 따른 합병증 증가의 가능성을 고려하여 제외하였다. 환자의 전체 및 무진행생존기간은 수술 받은 날을 기준으로 Kaplan-Meier법으로 산출하였고, 기존 문헌에 보고되고 있는 예후인자들과 각 환자에 조사된 방사선 선량, 표적체적 등이 생존율에 미치는 영향을 Log rank test 및 Cox regression analysis로 분석하였다. 추적관찰을 위해 정기적으로 MRI가 시행되었다. 결과: 전체환자의 중앙 생존기간 및 무진행 생존기간은 각각 $15{\pm}1.65$, $11{\pm}0.95$개월이었다. 중앙생존기간은 저선량군 및 고선량군이 각각 $14{\pm}0.94$개월, $21{\pm}5.03$개월로 고선량군에서 보다 나은 치료성적을 보여주었으며, 중앙무진행생존기간은 저선량군 $10{\pm}1.63$개월, 고선량군 $12{\pm}1.59$개월이었다. 특히 2년 생존율에 있어서 고선량군은 $44.7\%$로 $19.2\%$인 저선량군에 비해 훨씬 좋은 예후를 보였다. 단변량분석에서 예후에 영향을 미치는 중요인자로는 환자의 나이, 전신수행도, 종양의 위치, 수술절제범위, 표적체적, 방사선총선량 등이었다 다변량분석에서 통계적으로 유의한 인자는 환자의 나이(p=0.012), 수술절제범위(p=0.000), 방사선선량군(p=0.049)이었다. 방사선괴사와 같은 방사선으로 인한 직접적인 만성합병증은 추적관찰기간 동안 발생하지 않았다. 결론: 3차원 입체조형치료기법을 통하여 70 Gy까지의 방사선을 부작용 없이 조사할 수 있었고, 근치적 국소요법의 일환으로 방사선 선량증가가 전체 생존기간 및 무진행 생존기간을 향상시킬 수 있을 것으로 기대한다.

본 연구의 조사대상자는 전남 신안군 완도면 지역의 46세에서 83세 사이의 남자 88명과 여자 99명 총 187명을 대상으로 식생활의 서구화와 함께 최근 우리나라에서 급증하고 있는 심혈관질환과 당뇨병의 유발요인, 도서지역 주민의 식행동과의 관련성에 관한 연구 결과를 요약하면 다음과 같다. 전보에서 보고한 바와 같이(41) 조사대상자의 남녀 평균 연령은 각각 65.14세, 64.92세였고 평균 신장은 161.16 cm, 151.64 cm, 평균 체중은 63.03 kg, 56.46 kg, 평균 BMI는 24.33 $kg/m^2$, 24.48 $kg/m^2$, 평균 WHR은 0.94, 0.94였다. 일주일간의 아침식사 횟수는 남녀 모두 연령별, 성별 차이는 없었다. 매일 아침식사를 하는 사람은 남자 88.6%, 여자 96.0%로 여자의 매일 아침식사 비율이 남자보다 높았다. 과식정도는 남자는 연령 군별 차이가 있었고(p<0.01) 여자는 연령과 성별에 따른 차이는 없었다. 남자는 연령이 낮은 집단일수록 과식횟수가 유의적으로 많았는데(p<0.01) 여자도 비슷한 경향을 보였다. 이는 활동량과 현업종사 등의 이유일 것으로 보인다. 식사시간의 규칙성은 남녀 각각 규칙적 식사 38.6%, 37.4%, 때때로 규칙적 14.8%, 19.2%, 불규칙 46.6%, 43.4%로 각 군별 차이는 없었다. 식사량은 남자는 연령에 따라 차이가 없었으나 여자는 차이가 있었다(p<0.001). 여자는 나이가 많은 연령 군일수록 적게 먹었으며 많이 먹는다고 한 군은 60세 이하가 가장 많았고(69.2%) 연령 군별 식사량은 유의적인 차이를 보였다(p<0.001). 식사속도는 남녀 모두 연령별로 유의적인 차이가 있었고(p<0.05, p<0.01) 성별에 따른 차이도 있었다(p< 0.001). 남자는 빠르게(67%) 여자는 보통보다 느리게(67.5%) 먹는 것으로 나타났으며 성별에 따른 식사속도의 차이가 있었다(p<0.001). 아침식사 횟수는 매일, 주당 1${\sim}$2회, 3${\sim}$4회 먹는 사람의 혈중 중성지방 수준이 남자는 각각 151.88 mg/dL, 120.25 mg/dL, 175.00 mg/dL, 여자는 각각 145.78 mg/dL, 95.00 mg/dL, 100.00 mg/dL로써 세군 간에 유의적인 차이는 없었다. Total-cholesterol은 아침식사를 매일, 주당 1${\sim}$2회, 3${\sim}$4회 먹는 군이 남자는 각각 195.78 mg/dL, 161.00 mg/dL, 160.00 mg/dL로 매일 먹는 군이 다른 두 군에 비해 유의적으로 높았고(p<0.001), 여자도 각각 171.24 mg/dL, 90.00 mg/dL, 88.50 mg/dL로 남자와 마찬가지로 매일 먹는 군이 다른 두 군에 비해 유의적으로 높았다(p<0.001). 이 지역 주민의 혈청 콜레스테롤 평균이 한국인 정상 범위에 속하긴 하였으나 매일 아침식사를 하지 않는 여자의 혈청 총콜레스테롤이 108 mg/dL에도 미치지 못하는 것은 연령, 빈도의 차이 등 여러 요인이 있을 것으로 생각된다. 동맥경화 유발인자 중 하나인 LDL-cholesterol은 남자가 매일 먹는 군이 가장 낮게 나타났으며 여자는 아침식사를 매일, 주당 1${\sim}$2회, 3${\sim}$4회 먹는 군이 각각 112.80 mg/dL, 70.00 mg/dL, 78.00 mg/dL로 매일 아침식사를 하는 군이 다른 두 군에 비해 유의적으로 높게 나타났다(p<0.05). HDL-cholesterol은 남자는 세군 간에 차이를 보이지는 않았으며 여자는 아침식사를 매일, 주당 1${\sim}$2회, 3${\sim}$4회 먹는 군이 각각 49.39 mg/dL, 75.00 mg/dL, 72.00 mg/dL로 아침식사를 매일 하는 군에 비해 다른 두 군이 유의적으로 낮게 나타나 이는 지질대사의 변화와 관련이 있는 것으로 보인다(p<0.001). Atherogenic index는 아침식사를 매일, 주당 1${\sim}$2회, 3${\sim}$4회 먹는 사람 군이 남자는 각각 2.08, 2.87, 1.26으로 아침을 1${\sim}$2회 먹는 군과 3${\sim}$4회 먹는 군 사이에 유의적인 차이를 보였고(p<0.001), blood sugar는 남녀 모두 각 군별 유의적인 차이가 없었으며 본 조사대상자의 평균은 정상 범위에 있었다. 과식 정도에 따른 혈중지질, 혈당 수준을 살펴보면 혈중 중성지방은 남자는 일주일에 0${\sim}$1회, 2${\sim}$3회 과식이 각각 130.65 mg/dL, 154.06 mg/dL로 일주일에 2${\sim}$3회 과식하는 군이 유의적으로 높았다(p<0.05). 여자는 차이가 없었다. Total cholesterol은 남자가 일주일에 0${\sim}$1회, 2${\sim}$3회 과식하는 군이 각각 191.39 mg/dL, 181.76 mg/dL, 여자는 각각 167.92 mg/dL, 168.00 mg/dL로 남자는 0${\sim}$1회 과식하는 군이, 여자는 2${\sim}$3회 과식하는 군이 높게 조사되어 여성의 경우 남성과는 다른 양상을 보였는데 이는 본 연구대상 여성은 46세 이상으로 대부분이 폐경이 되어 지질대사의 변화와 관련이 있는 것으로 보인다. LDL-cholesterol은 남자는 차이가 없었으며 여자는 각각 112.63 mg/dL, 98.80 mg/dL로 일주일에 2${\sim}$3회 과식하는 군이 유의적으로 낮았다(p<0.05). HDL-cholesterol은 남자 각각 58.76 mg/dL, 51.59 mg/dL, 여자 각각 50.93 mg/dL, 45.30 mg/dL로 과식 횟수가 적은 군이 높게 나타나 좋은 식습관이 심혈관질환을 예방하는 것으로 알려진 HDL-cholesterol의 농도를 높이는 것으로 볼 수 있다. Atherogenic index는 남자가 각각 1.87, 2.19로 과식 횟수가 많은 군이 높은 경향을 보였고, 여자는 2.50, 2.43으로 남자와는 반대의 결과를 보였고 여자는 0${\sim}$1회 과식하는 군이 HDL-cholesterol이 높은데도 atherogenic index가 높은 것은 여성의 경우 폐경을 전후로 에스트로겐이 감소하여 당대사 및 지질대사에 영향을 미치기 때문으로 보인다. Blood sugar는 남자가 각각 84.34 mg/dL, 95.59 mg/dL로 일주일에 2${\sim}$3회 과식하는 군이 유의적으로 높았고(p<0.05), 여자도 각각 90.19 mg/dL, 99.80 mg/dL로 남자와 비슷한 결과를 보였다. 식사시간이 규칙적, 때때로 규칙적, 불규칙적인 군들 간에 혈중 중성지방은 유의성은 없지만 두군 모두 식사 시간이 불규칙적인 군이 높게 나타났다. Total-cholesterol은 남자가 각각 177.79 mg/dL, 216.85 mg/dL, 190.61 mg/dL로 식사시간이 때때로 불규칙적인 군이 다른 두 군에 비해 유의적으로 높았고(p<0.05), 여자는 각각 157.43 mg/dL, 159.53 mg/dL, 181.81 mg/dL로 식사시간이 규칙적인 군과 불규칙적인 군이 유의적인 차이가 있었다(p<0.05). LDL-cholesterol은 두군 모두 유의적인 차이는 없었다. HDL-cholesterol은 남자는 각각 54.49 mg/dL, 54.69 mg/dL, 50.50 mg/dL로 식사시간이 불규칙적인 군이 다른 두 군보다 낮았고 여자는 각각 49.58 mg/dL, 53.05 mg/dL, 49.89 mg/dL로 때때로 불규칙적인 군이 가장 높게 나타나 혈청지질은 연령, 성별, 식습관, 생활양식 등에 영향을 받는 것을 알 수 있었다. Atherogenic index는 남자가 각각 1.80, 2.20, 2.38로 불규칙적인 군이 유의적으로 높았고(p<0.01), 여자도 비슷한 결과를 보였다. Blood sugar는 남자가 각각 75.35 mg/dL, 115.31 mg/dL, 86.63 mg/dL로 때때로 불규칙적인 군이 다른 두 군에 비해 유의적으로 높았고(p<0.01), 여자는 각각 79.00 mg/dL, 89.59 mg/dL, 99.56 mg/dL로 불규칙적인 군이 규칙적인 군에 비해 유의적으로 높아(p<0.05), 식사시간이 불규칙적일수록 높아지는 경향을 보였다. 평소의 식사량이 적은 군, 보통, 많이 먹는 군의 남자는 유의적인 차이는 없었으나 보통 이상 먹는 군의 혈중 지질수준이 높았고 여자는 각각 148.69 mg/dL, 133.59 mg/dL, 148.69 mg/dL로 보통으로 먹는 군이 다른 두 군에 비해 유의적으로 낮았다(p<0.05). Total-cholesterol과 LDL-cholesterol은 남녀 모두 많이 먹는 군이 가장 높게 조사되었다. HDL-cholesterol은 남녀 모두 적게 먹는 군이 가장 높게 조사되었다. Atherogenic index는 남녀 모두 식사량이 많을수록 높아지는 경향을 보였다. Blood sugar는 남녀 모두 유의성은 없지만 식사량이 많을수록 높아지는 경향을 보였다. 따라서 식사량이 많으면 total-cholesterol, LDL-cholesterol, atherogenic index, blood sugar는 높고 HDL-cholesterol은 낮아지는 것을 알 수 있었다. 식사속도는 매우 빨리, 빨리, 보통, 천천히, 매우 천천히 먹는다고 답한 군들의 혈중 중성지방은 남자는 각각 131.43 mg/dL, 158.11 mg/dL, 281.50 mg/dL, 112.13 mg/dL, 139.60 mg/dL로 식사 속도가 보통이라고 답한 군은 다른 군들에 비해 유의적으로 높았다(p<0.001). 여자는 각각 155.25 mg/dL, 146.91 mg/dL, 115.40 mg/dL, 165.93 mg/dL, 146.57 mg/dL로 보통인 군이 가장 낮아 남자와는 상반된 결과를 보였고, 보통과 매우 빠르다, 천천히 먹는다고 한 군들 간에 유의적인 차이를 보였다(p<0.05). Total-cholesterol은 남자가 각각 183.57 mg/dL, 195.18 mg/dL, 215.50 mg/dL, 188.53 mg/dL, 163.60 mg/dL로 보통이다, 매우 느리다고 한 군들 간에 유의적인 차이를 보였으며(p<0.05) 여자는 차이가 없었다. LDL-cholesterol은 남자가 각각 110.71 mg/dL, 118.07 mg/dL, 150.00 mg/dL, 125.60 mg/dL, 126.80 mg/dL로 보통이라고 답한 군이 다른 군들 간에 유의적 차이를 보였다(p<0.05). HDL-cholesterol은 남자가 각각 54.00 mg/dL, 53.62 mg/dL, 41.50 mg/dL, 54.93 mg/dL, 50.30 mg/dL로 보통 또는 천천히 먹는다고 답한 군들 간에 유의적인 차이를 보였으며(p<0.05) 여자는 차이를 보이지 않았다. Atherogenic index는 남자가 보통으로 먹는 군이, 여자는 매우 빨리와 천천히 먹는다고 답한 군이 약간 높았다. Blood sugar는 남자가 각각 81.00 mg/dL, 80.22 mg/dL, 76.50 mg/dL, 112.73 mg/dL, 87.20 mg/dL로 천천히 먹는다고 한 군이 다른 군들과 비교하여 유의적으로 높았으며(p<0.01) 여자는 차이를 보이지 않았다. 이상의 결과에서 아침식사의 규칙성과 혈중지질 농도와의 관계를 살펴보면, 남녀 모두 규칙적으로 아침식사를 하는 경우에 혈청 총콜레스테롤 농도와 혈당이 높게 나타났고 특히 여자는 LDL-cholesterol, HDL-cholesterol 농도도 높은 것으로 조사되었다. 과식횟수는 남녀 모두 과식횟수가 적을수록 HDL-cholesterol 농도는 높고, 혈당은 낮았고, 남자의 경우에는 혈청 중성지방과 LDL-cholesterol 농도가 낮았다. 식사시간의 규칙성은 규칙적인 식사를 하면 남녀 모두 혈청 중성지방 농도, 총 cholesterol 농도, 동맥경화지수, 혈당이 낮았고, 여자는 LDL-cholesterol 농도도 낮았다. 한 번 먹을 때의 식사량은 남녀 모두 많이 먹으면 혈청 중성지방 농도와 총 cholesterol 및 LDL-cholesterol 농도, 동맥경화지수, 혈당이 높게 나타났고, HDL-cholesterol 농도는 남자는 낮았고 여자는 높게 조사되었다. 따라서 과식횟수가 적고 식사시간이 규칙적이며, 1회 섭취량이 적을수록 혈청내의 지질조성, 혈당 및 동맥경화지수가 적당한 상태로 나타나서 심혈관질환의 예방에 도움을 줄 수 있는 식사행동으로 보여진다. 본 결과를 토대로 중${\cdot}$장년층을 대상으로 식사의 규칙성과 섭취 적당량에 대한 영양교육도 이루어지기를 기대한다.

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.
