타이 정치체제가 관료적 정체(bureaucratic polity) 혹은 반민주주의(semi-democracy)로 회귀하였다고 얘기된다. 그러나 이와 같은 시각은 국왕의 자문기구인 추밀원(Privy Council)의 정치적 개입을 제대로 드러내지 못한다. 이러한 맥락에서 이 논문은 근대적 절대군주제라는 분석적 개념을 통해 타이식 입헌군주제의 독특한 특징을 밝히고 있다. 요컨대 '네트워크 정치'(network politics)에 기반하는 타이식 입헌군주제(Thai way of constitutional monarchy)는 "국왕은 군림하되 통치하지 않는다"라는 규범에 토대한 전형적인 입헌군주제와 배치된다. 이는 타이 국왕이 실제로는 정치 위에 있는 것이 아니라 정치 안에 있음을, 또 정치적 갈등을 해결하고 군주제를 보위하기 위해 다양한 방식으로 정치에 개입하였음을 의미한다. 이 과정에서 국왕은 불교의 교리를 실천하는 반인반신이자 국가통합의 중심으로 추앙되었다. 심지어 왕실이 관여된 1976년 10월 6일 유혈참사 이후에도 국왕의 신성한 지위는 도전을 받지 않았고 국왕모독죄는 더욱 가혹한 처벌을 받게 되었다. 그 이후 국왕모독죄는 군부 쿠태타의 주된 명분이 되었다. 특히 군주 네트워크와 근대화 과정에서 성장한 탁신 네트워크에 기반한 부르주아 정체 간의 대격돌로부터 야기된 2006년 쿠테타와 이후 친탁신계 정부를 전복한 2014년 쿠테타를 계기로 국왕모독죄 사례가 급증하였다. 관료적 정체, 반민주주의, 민주주의를 포괄하는 타이에서의 근대적 절대군주제는 군부, 지식인, 민주당, 심지어 일부 시민사회조직들로부터 지지를 받는 국왕모독죄에 의해 지지되고 있다.

아동을 위한 단어인지도 검사 (word recognition test, WRT)는 아동의 의사소통장애정도를 진단하고, 보청기 사용을 위한 처방을 하고, 청각재활과 언어치료의 계획을 수립하고, 병변부위를 판단하는데 유용하게 사용될 수 있다. 한국표준 학령전기용 단음절어표 (Korean standard monosyllabic word lists for preschoolers, KS-MWL-P)는 문헌에서 주어진 기준을 고려하여 개발되었다. 그러나 KS-MWL-P의 저자들은 어표의 개발과정 중 단지 8명만 참여하여 분석된 심리음향 기능곡선을 검증하기 위하여 더 많은 대상을 포함한 연구를 제안하였다. 그러므로 본 연구의 목적은 KS-MWL-P 어표의 제한성을 보완하기 위하여 심리음향기능분석으로 어표의 동질성을 연구하고자 한다. 정상청력을 가진 23명의 학령전기아동을 대상으로 100개의 KS-MWL-P단어가 그림과 함께 제시되었다. -10에서 40 dB dBIH.까지 여러 강도에서 각 단어의 인지도 검사를 계산하여 20%와 80% 정답률 기준의 선형기울기로 심리음향기능곡선을 수집하고 분석하였다. 연구결과 강도에 따라 정답률이 증가하는 S자형 심리음향기능곡선이 나타났고 각 단어와 표간 통계적 유의성은 나타나지 않았다. 표간 유사한 그래프 형태를 통해 우수한 동질성을 보여주었고 표 1,2,3,4의 평균기울기는 4.48, 3.86, 4.65, 4.50 이었으며 일원 분산분석으로 분석할 때 표간 유의성이 없는 것 (p>0.05)으로 나타나서 표간 난이도의 동질성에 문제가 없는 것으로 확인되었다. 그리고 항목 번호의 순서에 따른 기울기의 P값도 표 1, 2, 3, 4에서 0.93, 0.59, 0.91, 0.70으로 모두 유의하지 않아 모든 표에서 $1{\sim}10$, $1{\sim}20$, $1{\sim}25$의 항목간 차이는 없는 것으로 나타났다. 그러나 KS-MWL-P는 낮은 번호의 항목은 더 어린 연령을 위하여 쉬운 단어로 배치하고자 하였으나 본 연구결과는 그렇지 못한 것으로 나타났다. 이러한 점을 고려할 때 어린 연령대를 위한 쉬운 단어가 낮은 항목에 배치되도록 항목의 배치를 재조정하여야 할 것으로 사료된다. 이러한 점을 제외하면 결론적으로 KS-MWL-P는 학령전기를 위한 임상과 재활의 평가 및 훈련도구로 유용한 것으로 입증되었다.

The problem addressed by this study was to determine the effect of nurse - patient agreement on the means to achieve nursing goals in the early postpartum period of primiparous mothers. It was hypothesized that the experimental treatment would result in hegher self-confidence and satisfaction in maternal role performance. This purpose was to contribute to the planning of nursing care to enhance self- confidence and satisfaction in maternal role performance and to the development of relevant nursing theory. Especially, the early postpartum period is crucial toward in recovery from childbirth and attainment of the maternal role. Maternal role attaintment is a complex social and cognitive process of stimulus -response accomplished by learning. Most women attain the maternal role sucessfully. But, some primiparous mothers experience difficultites in attainment of the maternal role due to lack of experience and knowledge. Self-confidence and satisfaction in maternal role performance are important factors in attainment and adjustment to the maternal role (Mercer, 1981a, 1981b ; Lederman, Weigarten, and Lederman, 1981 :Bobak and Jensen, 1985). Nursing is defined as behaviors of nurses add patients that attain nursing goals through action, reaction, interaction, and transaction. For attainment of nursing goals, active participating transactions must occur by agreement on the means to achieve those goals through nurse -patient mutual goal setting and establishment of their active relationships(King, 1981, Ha, 1977). Based on King's theory of goal attainment (1981), this stuy was planned as a non-equivalent control group, non -synchronized quasi -experimental design using agreement on the means to achieve nursing goals in early postpartum as the experimental treatment. The data were collected from July 20 to Sep. 1, 1991 by questionnaires with 60 primiparous mothers planing to breast feed after normal deliveries at W hospital in Pusan, Korea. The subjects were divided into a control group(conventional group) -those admitted from July 20 to Aug. 12, and an experimental group(agreement group) - those admitted from Aug. 13 to Sep. 1. The instument for agreement on the means to nursing goals in the early postpartum period included five steps - identification of disturbances of problems through action, reaction, and interaction with primiparous mothers : mutual early postpartal nursing goal setting : exploration of the means to achieve goals ; agreement on the means (self- care, ealry maternal -infant contact, performance of mothering behavior, and communicating about the infant's behavior and health condition) : implementation of the means. This instrument was developed on the basis of King's elements that lead to transactions in nurse-patient interactions. Lederman et al's (1981) scale for Confidence in ability to cope with tasks of motherhood and Lederman et al's(1981) scale for Mother's satisfaction with motherhood and infant care were used to measure self-confidence and satisfaction in maternal role performance ·with the subjects immediately after admission and on the day of discharge. Self-care performance in the experimental group was measured by self -evaluation tool developed by the investigator from the literature concerned. The tools to measure Pelf-confidence and satisfaction in maternal role performance, and the tool to measure self-evaluation of self-care performance were tested for internal reliability. Cronbach's Alphas were 0.94, 0.94, and 0.63. The data were analysed by using in S.P.S.S. computerized program and included percentage, x²-test, t-test, ANOVA, and Pearson Correlation Coefficient. The conclusions obtained from this study are summerized as follows : 1. The degree of self-confidence in maternal role performance of the total subjects group measured before the experimental treatment was above average with a mean score of 2.77(range 2.14-3.64). Out of 14 items, those with relatively high mean scores were ‘I would like to be a better mother than I am’(3.95), and ‘I have my doubts about whether I am a good mother’(2.87). Those with low mean scores were ‘I know that my baby wants most of the times’(2.28), ‘When the baby cries, I can tell what she /he wants’(2.37), and ‘I have confidence in my ability to care for the baby’(2;50). That is, the self - confidence of Primiparous mothers was considerably high in mothering, but rather low in activities concerning the infant care and understanding of the infant behavior. The degree of satisfaction in maternal role performance of the total subjects group measured before the experimental treatment was high with a mean score of 3.18(range 1.92-3.92). Out of 13 items, those with relatively high mean scores were ‘I am glad 1 had this baby now’(3.75), ‘I play with the baby between feedings when s/he is awake and quiet’(3.67), and ‘I enjoy being a mother’(3.27). Those with low mean scores were ‘I am upset about having too many responsibilities as a mother’(2.78), ‘It bothers me to get up for the baby at night’(2.82), and ‘I get annoyed if the baby frequently interrupts my activities’.(2.82), That is, the satisfaction of primiparous mothers was considerably high in mothering and infant care, but rather low in restraints in time or on the mother's self accomplishment and development. 2. Agreement on the means to achieve nursing goals in the early postpartum period included process of mutual goal setting, exploration of the means to achieve goals, and ahreement in concert means to achieve goals based on the mothers' condition, concerns, self-perception of the nurse - patient interactions. In the process of agreement, there was agreement that the means to achieve goals should be through trust and establishment of active relationships with the nurse through identification of problems according to planned nursing goals and active interaction, such as explanations, teaching, changing of opinions, acceptance or rejection of explanations, and proposing of questions. Therefore agreement on the means to achieve nursing goals in the early postpartum period appears to be an effective nursing intervention for primiparous mothers. 3. The degree of self- confidence in maternal role performance of the exprimental group was higher than that of the control group(t＝3.95, p＜0.01). Out of 14 items, those with higher score in the experimental group were ‘I would like to be a better mother than I am’(t＝1.93, p＜0.05), ‘I know that my baby wants most of the times’(t＝2.75, p＜0.01), ‘When the baby cries, 1 can tell what she/he wants’(t＝2.10, p＜0.05), ‘I have confidence in my ability to care for the baby’(t＝3.72, p＜0.01), ‘I trust my own judement in deciding how to care for the baby’(t＝1.96, p＜0.05), ‘I feel that I know my baby and what to do for him /her’(t＝2.44, p＜0.01), ‘I am concerned about being able to meet the baby's needs’(t＝2.87, p＜0.01), ‘I know what my baby likes and dislikes’(t＝3.26, p＜0.01), ‘I don't know to care for the baby as well as I should’(t＝2.07, p＜0.05), and ‘I am unsure about whether I give enough attention to the baby’(t＝3.04, p＜0.01), That is, the degree of self-confidence in mothering, activities concerning infant care, and understanding of infant behavior of the experimental group was higher than that of the control group. Therefore, the first hypothesis, that the degree of self-confidence in maternal role performance of the experimental group would be higher than that of the control group, was supported(t＝3.95, p＜0.01). 4. The degree of satisfaction in the maternal role performance of the exprimental group was higer than that or the control group(t＝2.31, p＜0.05). Out of 13 items, those with higher score in the experimental group were ‘I am glad I had this baby now’(t＝2.29, p＜0.05), ‘I enjoy taking care of the baby’(t＝2.4g, p＜0.01), ‘It is boring for me to care for the baby and do the same thing over and over’(t＝2.87, P＜0.01), ‘I am unhappy with the amount of time I have for activities other than childcare’(t＝2.51, p＜0.01), and ‘When bathing and diapering the baby, I would like to be doing something else’(t＝2.43, p＜0.01). That is, the degree of satisfaction in mothering, infant care, and restraints in time of on the mother's self accomplishment and development in the experimental group was higher than that of the control group. Therefore, the second hypothesis, that the degree of satisfaction in maternal role performance of the experimental group would be higher than that of the control group, was supported(t＝2.31, p＜0.05). 5. The third hypothesis, that the higher the degree of satisfaction in materenal role performance, the higher the degree of self-confidence in materenal role performance in the experimental group, was supported (r＝0.57, p＜0.01)

Hemodialysis is essential treatment for the chronic renal failure patient's long-term cure and for the patient management before and after kidney transplantation. It sustains the endstage renal failure patient's life which didn't get well despite strict regimen and furthermore it becomes an essential treatment to maintain civil life. Bursing implementation in hemodialysis may affect the significant effect on patient's life. The purpose of this study was to obtain the basic data to solve the hypotension problem encountable to patient and the blood loss problem affecting hemodialysis patient'a anemic states by incomplete rinsing of blood in coil through all process of hemodialysis. The subjects for this study were 44 patients treated hemodialysis 691 times in the hemodialysis unit, The .data was collected at Gang Nam 51. Mary's Hospital from January 1, 1981 to April 30, 1981 by using the direct observation method and the clinical laboratory test for laboratory data and body weight and was analysed by the use of analysis of Chi-square, t-test and anlysis of varience. The results obtained an follows; A. On clinical laboratory data and other data by dialysis Procedure. The average initial body weight was 2.37 ± 0.97kg, and average body weight after every dialysis was 2.33 ± 0.9kg. The subject's average hemoglobin was 7.05±1.93gm/dl and average hematocrit was 20.84± 3.82%. Average initial blood pressure was 174.03±23,75mmHg and after dialysis was 158.45±25.08mmHg. The subject's average blood ion due to blood sample for laboratory data was 32.78±13.49cc/ month. The subject's average blood replacement for blood complementation was 1.31 ±0.88 pint/ month for every patient. B. On the hypotensive state and the coping approaches occurrence rate of hypotension was 28.08%. It was 194 cases among 691 times. 1. In degrees of initial blood pressure, the most 36.6% was in the group of 150-179mmHg, and in degrees of hypotension during dialysis, the most 28.9% in the group of 40-50mmHg, especially if the initial blood pressure was under 180mmHg, 59.8% clinical symptoms appeared in the group of“above 20mmHg of hypotension”. If initial blood pressure was above 180mmHg, 34.2% of clinical symptoms were appeared in the group of“above 40mmHg of hypotension”. These tendencies showed the higher initial blood pressure and the stronger degree of hypotension, these results showed statistically singificant differences. (P=0.0000) 2. Of the occuring times of hypotension,“after 3 hrs”were 29.4%, the longer the dialyzing procedure, the stronger degree of hypotension ann these showed statistically significant differences. (P=0.0142). 3. Of the dispersion of symptoms observed, sweat and flush were 43.3%, and Yawning, and dizziness 37.6%. These were the important symptoms implying hypotension during hemodialysis accordingly. Strages of procedures in coping with hypotension were as follows ; 45.9% were recovered by reducing the blood flow rate from 200cc/min to 1 00cc/min, and by reducing venous pressure to 0-30mmHg. 33.51% were recovered by controling (adjusting) blood flow rate and by infusion of 300cc of 0,9% Normal saline. 4.1% were recovered by infusion of over 300cc of 0.9% normal saline. 3.6% by substituting Nor-epinephiine, 5.7% by substituting blood transfusion, and 7,2% by substituting Albumin were recovered. And the stronger the degree of symptoms observed in hypotention, the more the treatments required for recovery and these showed statistically significant differences (P=0.0000). C. On the effects of the changes of blood pressure and osmolality by albumin and hemofiltration. 1. Changes of blood pressure in the group which didn't required treatment in hypotension and the group required treatment, were averaged 21.5mmHg and 44.82mmHg. So the difference in the latter was bigger than the former and these showed statistically significant difference (P=0.002). On the changes of osmolality, average mean were 12.65mOsm, and 17.57mOsm. So the difference was bigger in the latter than in the former but these not showed statistically significance (P=0.323). 2. Changes of blood pressure in the group infused albumin and in the group didn't required treatment in hypotension, were averaged 30mmHg and 21.5mmHg. So there was no significant differences and it showed no statistical significance (P=0.503). Changes of osmolality were averaged 5.63mOsm and 12.65mOsm. So the difference was smaller in the former but these was no stitistical significance (P=0.287). Changes of blood pressure in the group infused Albumin and in the group required treatment in hypotension were averaged 30mmHg and 44.82mmHg. So the difference was smaller in the former but there is no significant difference (P=0.061). Changes of osmolality were averaged 8.63mOsm, and 17.59mOsm. So the difference were smaller in the former but these not showed statistically significance (P=0.093). 3. Changes of blood pressure in the group iutplemented hemofiltration and in the Uoup didn't required treatment in hypotension were averaged 22mmHg and 21.5mmHg. So there was no significant differences and also these showed no statistical significance (P=0.320). Changes of osmolality were averaged 0.4mOsm and 12.65mOsm. So the difference was smaller in the former but these not showed statistical significance（P=0.199). Changes of blood pressure in the group implemented hemofiltration and in the group required treatment in hypotension were averaged 22mmHg and 44.82mmHg. So the difference was smatter in the former and these showed statistically significant differences (P=0.035). Changes of osmolality were averaged 0.4mOsm and 17.59mOsm. So the difference was smaller in the former but these not showed statistical significance (P=0.086). D. On the changes of body weight, and blood pressure, between the group of hemofiltration and hemodialysis. 1, Changes of body weight in the group implemented hemofiltration and hemodialysis were averaged 3.340 and 3.320. So there was no significant differences and these showed no statistically significant difference, (P=0.185) but standard deviation of body weight averaged in comparison with standard difference of body weight was statistically significant difference (P=0.0000). Change of blood Pressure in the group implemented hemofiltration and hemodialysis were averaged 17.81mmHg and 19.47mmHg. So there was no significant differences and these showed no statistically significant difference (P=0.119), But in comparison with standard deviation about difference of blood pressure was statistically significant difference. (P=0.0000). E. On the blood infusion method in coil after hemodialysis and residual blood losing method in coil. 1, On comparing and analysing Hct of residual blood in coil by factors influencing blood infusion method. Infusion method of saline 200cc reduced residual blood in coil after the quantitative comparison of Saline Occ, 50cc, 100cc, 200cc and the differences showed statistical significance (p < 0.001). Shaking Coil method reduced residual blood in Coil in comparison of Shaking Coil method and Non-Shaking Coil method this showed statistically significant difference (P < 0.05). Adjusting pressure in Coil at OmmHg method reduced residual blood in Coil in comparison of adjusting pressure in Coil at OmmHg and 200mmHg, and this showed statistically significant difference (P < 0.001). 2. Comparing blood infusion method divided into 10 methods in Coil with every factor respectively, there was seldom difference in group of choosing Saline 100cc infusion between Coil at OmmHg. The measured quantity of blood loss was averaged 13.49cc. Shaking Coil method in case of choosing saline 50cc infusion while adjusting pressure in coil at OmmHg was the most effective to reduce residual blood. The measured quantity of blood loss was averaged 15.18cc.

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.

연구배경 : 특발성 폐섬유회증은 병리학적으로 폐구조가 파괴되면서 섬유아세포 및 교원질이 간질 및 폐포내에 침작하는 질환으로 교원질의 침착은 cytokine 및 성장촉진인자들에 의한 교원질생성의 증가 뿐 아니라 교원질의 분해흡수의 감소도로 초래될 수 있다. IPF의 또 다른 특징인 폐구조의 파괴 및 폐보내 섬유화 현상은 기저막 파괴로 인한 섬유아세포 등의 폐포내 유입 및 비정상적 증식이 기전으로 생각되므로 기저막의 주요 성분인 제4형 교훤질올 분해하는 Matrix metalloproteinase(MMP)-2와 MMP-9이 IPF의 발병기전에 중요한 역할을 할 것으로 추정되고 있다. 또한 병이 계속 활발히 진행되는 상태에서는 이들 효소의 농도도 높올 것이 예상되므로 본 연구는 특발성 폐섬유화증에서 질병의 진행파정에 따른 기관지폐포세척액(BALF)내 MMP 농도 및 BALF내 세포분포와의 IPF에서 MMP의 역할 및 예후인자로서의 가능성을 규명하고자 시행되었다. 방 법 : 서울중앙병원에서 진단된 41명(연령 $59.82{\pm}1.73$세, 남:여=23:18)의 IPF환자들과, IPF진단은 받았으나 1년 이상 치료하지 않고도 병이 진행되지 않았던 안정군 16명($63.6{\pm}2.8$세, 남:여=13:3) 및 정상 대조군 7명을 대상으로 BAL액과 AM배양 배지에서 MMP-2와 MMP-9농도를 zymography와 densitometry에 의한 정량분석을 시행하였고, TIMP-1 농도는 상업용 ELISA kit로 측정하였다. 결 과 : 1) BAL 액내 총 세포수(${\times}10^6/ml$)는 IPF환자군($3.40{\pm}0.20$), 안정군($2.92{\pm}0.39$), 대조군($0.91{\pm}0.15$)간 유의한 차이를 보였고 AM수효(${\times}10^5/ml$)와 호중구 수(${\times}10^5/ml$)는 IPF 환자군($24.74{\pm}1.88$, $2.15{\pm}0.35$)과 안정군($19.16{\pm}2.26$, $0.63{\pm}0.11$)에서 대조군($7.36{\pm}1.04$, $0.052{\pm}0.038$)에 비하여 유의하게 높았다(p<0.05). 호산구비율도 IPF 환자군($2.83{\pm}0.66%$)과 안정군($1.50{\pm}0.42%$)에서 대조군($0{\pm}0%$)에 비하여 유의하게 높았으나(p<0.05), 림파구수나 비율은 차이가 없었다. 2) Zymography에 의한 육안적 관찰에서 IPF환자군은 34/41(82.9%), 안정군은 9/15(60%), 각각 band를 관찰하여 대조군 0/6(0%)과 차이를 보였다. 3) BALF내 MMP-2는 IPF환자군($1.36{\pm}0.28$)은 안정군($0.46{\pm}0.13$)에 비하여, 또 안정군도 대조군($0.08{\pm}0.09$)에 비하여 유의하게 높았다. MMP-9은 IPF 환자군($0.31{\pm}0.058$)과 안정군($0.22{\pm}0.078$)에서 대조군($0.002{\pm}0.004$)보다 높았다. TIMP-1도 IPF환자군($36.34{\pm}8.62{\mu}g/ml$)과 안정군($20.83{\pm}8.53{\mu}g/ml$)에서 대조군($2.80{\pm}1.05{\mu}g/ml$)에 비하여 유의하게 높았다(p<0.05). 4) AM배양액에서는 MMP-9만이 역시 IPF군에서($0.80{\pm}0.10$) 대조군보다($0.23{\pm}0.081$) 높았다. 5) BALF내 MMP-2는 전체 세 포수(r=0.298)와 호중구수(r=0.357)와 유의한 상관관계를 보였으나(p<0.05), AM수(r=0.096)나 임파구수(r=0.100)와는 상관관계가 없었고, MMP-9은 호중구수(r=0.407) 및 임파구수(r=0.574)와 유의한 상관관계를 보였다. TIMP-1은 전체 세포수(r=0.338, p<0.05) 및 호중구수(r=0.449, p=0.059)와 상관관계의 경향을 보였다. 결 론 : 본 연구의 결과로 MMP와 TIMP는 IPF의 병인에 있어서 중요한 역할을 하며, BALF내 MMP농도는 IPF의 활성도와 연관이 었을 것으로 추정된다.

핵의학검사에서 $^{131}I$은 갑상선암 및 질환의 진단, 치료등 핵의학 검사에서 많이 사용되고 있다. $^{131}I$은 ${\gamma}$선과 ${\beta}^-$선을 방출하여 검사와 치료를 할 수 있고, 높은 집적율과 신장을 통한 빠른 배설이 용이 하지만, $^{131}I$(364 keV)은 $^{99m}Tc$(140 keV)보다 고에너지이기 때문에 작업을 수행 시 조작 및 투여 과정에서 $^{99m}Tc$보다 술자의 피폭을 줄이기 위해 외부피폭 방어의 3요소인 거리, 시간, 차폐 중에 차폐에 주안점을 두어 $^{131}I$ 조작 시 차 폐체 착용 전과 후의 피폭선량의 차이를 비교하고자 한다. Apron(보통 Pb 0.5 mm) 착용 시 $^{99m}Tc$은 90%이상이 차폐가 되지만, $^{131}I$은 고에너지이기 때문에 차폐효과가 비교적 낮고, 고용량의 경우 산란선(2차) 및 제동방사선의 영향으로 오히려 더 피폭을 받을 수 있다. 하지만 저용량(74 MBq) 고에너지의 경우 이에 대한 특별한 보고나 Guide Line이 마련되어 있지 않아, $^{131}I$ 조작 시 Apron 착용 유무에 따른 술자의 피폭선량을 정량적으로 분석하고자 한다. 본원 핵의학과에서 2014년 6월부터 2014년 12월까지 7개월 동안 갑상선암 치료 및 진단을 위한 저용량$^{131}I$을 투여하기 위해 방문한 갑상선암 환자를 대상으로 준비과정부터 투여 시까지 연구기간 동안 갑상선, 가슴, 고환 3곳에 Apron 안쪽과 바깥쪽 각각 1개씩 총 6개의 TLD를 부착한 뒤 $^{131}I$검사 과정부터 투여 시 까지의 방사선 피폭선량을 측정하였다. 총 작업시간은 설명시간 3분, 분배시간 1분, 투여시간 1분으로 각각 1인당 5분이내로 설정하였다. TLD 위치설정은 일반적으로 피폭선량을 측정하는 가슴과 방사선 감수성이 높은 갑상선 및 고환으로 설정하였다. 준비과정은 $^{131}I$을 $2m{\ell}$ 주사기를 이용해 74MBq을 분배한 뒤 생리식염수와 희석해 $2m{\ell}$의 용량을 만들어 분배한다. $^{131}I$을 분배 후 환자에게 투여 시 컵에 물을 $100m{\ell}$ 담고 분배한 $^{131}I$을 희석하여 환자 1 m 정도 거리를 두고, 경구투여 한다. 그리고 경구투여 한 $2m{\ell}$ 주사기와 컵을 폐기하는 과정을 Apron과 TLD를 착용한 상태에서 시행하였다. Apron과 TLD는 방사선 피폭이 미치지 않는 보관실에 따로 보관하였고, 서울방사선 서비스에 의뢰하여 피폭선량을 측정하였다. 연구기간 동안 저용량 $^{131}I$ 검사 시 갑상선, 가슴, 고환 부위에 Apron 안과 밖d[착용한 TLD의 매월 누적선량을 인원수로 나눈 결과를 가지고, SPSS Version. 12.0K를 이용해 Wilcoxon Signed Rank Test를 사용하여 통계를 시행하였다. 그 결과 갑상선(p = 0.345), 가슴(p = 0.686), 고환(p = 0.715)은 모두 p > 0.05으로 유의한 차이가 없음을 알 수 있었다. 그리고 연구기간 동안의 총 누적선량의 변화를 백분율로 환산하였을 때, 갑상선 -23.5%, 가슴 -8.3%, 고환 19.0%로 나타났다. Wilcoxon Signed Rank Test를 사용한 결과 통계적으로 유의한 차이가 없는 것으로 나타났다(p > 0.05). 또한 7개월간의 누적선량으로 차폐율을 계산 했을 때 에는 Apron 안쪽과 바깥쪽의 피폭선량의 변화가 불규칙적으로 나타나는 결과를 보였다. 이 결과는 백분율로 표현 시 변화폭이 커보이지만, 누적 피폭선량이 소수점 이하이므로 큰 변화라고 보기 어렵다. 그러므로 고에너지 저용량 $^{131}I$ 투여 시 Apron을 착용유무와 상관없이 일정한 거리를 두고 최대한 빠른 시간 내에 투여를 종료하는 것이 피폭선량을 줄이는 데 도움이 될 것이다. 본 연구는 $^{131}I$ 투여시간을 1인당 각 5분 이내로 투여 할 수 있도록 제한하고, 거리를 1 m로 일정하게 하여 작업 할 수 있도록 하였으나 통계 시 N수가 적어서 비모수적인 방법으로 통계를 시행함으로써 정확한 결과를 얻기에 부족한 부분이 있었다. 또한 저용량 $^{131}I$ 투여 시 각 1인당 피폭선량을 직독식 선량으로 측정하지 못하고, TLD를 이용한 누적선량으로 측정한 결과 값이므로 전자선량계 및 포켓선량계를 이용한 측정이 이루어진다면 더 효과적인 결과를 얻을 수 있을 것으로 사료된다.
