Despite the intensive family Planning program of the government, which has reduced the :average population growth to 2.0 percent in 1970, the continuing high fertility rates and poor family planning services in urban slum areas has been continually pointed out by various evaluation seminars. Thus, it was felt that a study of the current status of family planning in an urban slum population was needed. The aims of the study were to: (1) delineate the general characteristics of the urban slum population (2) discover the knowledge, attitudes, and practice of family planing. (3) determine what was felt to be the ideal number of children. (4) determine the status of induced abortion. A random stratified sample of 200 women was selected from a population of 3, 118 married women, 20-49 years of age, living in the Yonsei Community Health Project area and registered at the Yonhee Community Health Service Institute. The respondents were interviewed by the investigates, using a pretested questionary, from the period of October 1 to October 30, 1972. The findings of the Study were as follows: 1. Afore than half of the respondents were in the high fertility age group (25-34): of lower educational level (under primary School) : from rural areas: and with unstable sources of income. 2. The average respondent had 3.6 living children. 3. Most of the respondents had knowledge of contraceptive methods such as the Loop(78, 5%) and Oral pill (87.0%). 4. Seventy seven percent of the respondents recognized the Health Center as an available source for family planning. 5. About seventy percent of the respondents approved of family planning. 6. Eighty four point five percent of all the respondents answered that using contraceptives is harmful to maternal health. 7. Currently, 21.0 percent of the respondents were using contraceptives, while 40.0 percent of the respondents were current users or had used contraceptives. 5. Of the respondents who had ever stopped using contraceptives, 78.0 percent gave side effects as the reason they discontinued the method. 9. The average number of ideal children reported by the respondents was 3.5. 10. If they had only 2 daughters, 85.5 Percent of the respondents thought they must have more children. 11. Sixty nine point five percent of the respondents approved of induced abortion for unwanted pregnancies, while 34.5 percent of the respondents had experienced induced abortion for unwanted pregnancies. The mean number of induced abortion for unwanted pregnancies was 0.7. 12. The result of this study showed that such urban slum population would be one of the most important target of the family planning services, therefore further social-psychological researches with technical development on this area are recommended.

Purpose: The purpose of this study was to investigate drinking motives and the drinking-related problems of Korean high school students at a city in Jeonbuk province. Methods: There were 657 students from two academic and two vocational high schools at J city in Jeonbuk province. The sample was collected using a stratified sampling method and the data was collected from June 30th to July 16th 2003. The study instrument used to examine drinking motive was a 20-item summated scale (Cronbach's ${\alpha}$ = .95) and for drinking-related problems was an 18 item summated scale (Cronbach's ${\alpha}$ = .91). The data was analyzed using SPSS/PC+ by percentage, x2-test, t-test and correlations. Results: 1. Drinking experience: Among the high school students, 74.3% of them had drinking episodes. Female students started drinking later (x2 = 12.857, p = .002) and had more drinking friends (x2 = 7.785, p = .020) than males. Vocational school students drank more frequently (x2 = 32.138, p = .001), had more heavy drinking episodes (x2 = 40.370, p = .001). 2. Drinking motives & Drinking-related problems: The mean score of drinking motives was $31.2{\pm}11.12$ out of 80 and that of drinking-related problems was $21.8{\pm}5.85$ out of 72 points. Neither score were stronger was significantly different according to gender and grade. On the other hand, both drinking motives (t = -4.077, p = .001) and drinking-related problems (t = -3.423, p = .001) were stronger in vocational school students than in academic school students. The correlation between drinking-related characteristics and problems were weak (from r = .286 to r = .520) but the correlation within the subcategories of drinking motives was high such as between enhancement and coping (r = .822) and enhancement and social motives (r = .822). Conclusion: The majority of Korean high school students start to drink during their junior high school days. Drinking motives and drinking-related problems were not serious but the drinking motives and the drinking-related problems are stronger among vocational school students. As a result, school-based health education and counseling programs should focus on solving drinking motives than on drinking-related problems.

BACKGROUND/OBJECTIVES: Accumulating evidence has shown the beneficial effects of isoflavone on health. There is limited information on the usual isoflavone intake for Koreans. This study examined the usual intake of total isoflavone and its major food sources in Koreans according to age and gender. SUBJECTS/METHODS: The dietary intake data of 21,271 participants aged 1 yrs and older from the Korea National Health and Nutrition Examination Survey (KNHANES) VII 2016-2018 were analyzed. The average isoflavone intake was estimated based on the 24-h dietary recall data in KNHANES and the isoflavone database from the Korea Rural Development Administration (RDA) and literatures. The usual isoflavone intake was estimated by applying the ratio of within- and between-participant variance estimated from the 2009 KNHANES data to the 7th KNHANES (2016-2018) data. The variance of the isoflavone intake was calculated using MIXTRAN macro with intake data for two days in the 2009 KNHANES. Complex sample analysis with stratified variables and integrated weights was conducted. RESULTS: The mean total isoflavone intake in the Korean population aged 1 yrs and older (n = 21,271) was 139.27 mg/d, which was higher than the usual intake of 47.44mg/d. Legumes were a major contributing food group (91%), with arrowroot being a major individual contributor to the isoflavone intake (67.2%), followed by 21.3% of soybean, 5.4% of bean sprouts, and 2.1% of tofu. The usual isoflavone intake was highest in the participants aged 50 to 64 yrs old and increased with age until 50 to 64 yrs and then decreased with further increases in age. The usual isoflavone intake of participants aged 65 yrs and older was higher for men than for women, showing gender differences. CONCLUSIONS: The usual dietary intake of isoflavone varied according to age and gender in the Korean population. This study showed that the usual isoflavone intake was lower than the average isoflavone intake. The difference between percentiles of the usual isoflavone intake was similarly smaller than the average intake. An estimation of average intake can be hindered by the occasional consumption of foods high in isoflavones, suggesting that the usual intake estimation method can be more appropriate. Further research will be needed to establish isoflavone dietary guidelines regarding the effects of isoflavone intake on health outcomes.

부모의 사회적인 통제와 A형행동양상과의 관계를 조사해 보기 위해서 대구시에 소재하는 3개의 대학 재학생을 대상으로 1988년 10월과 11월 초순에 걸쳐서 설문지조사를 실시했는데 분석에 이용된 인원은 803명이었다. A형 행동양상은 Student Jenkins Activity Survey(SJAS, 축약형)로 측정을 했으며, 부모의 사회적 인 통제는 Bernstein 과 Brandis의 Index of control and communication을 이용했는데 중앙값으로 이분화되었다. 대상인원의 평균 연령은 20.7세(표준편차 2.2)였고, SJAS의 총점은 평균 5.6, 표준편차 2.7의 분포를 보였으며 중앙값은 5였다. 출신지, 성별, 사회경제적인 지위를 기반으로 시행한 층화분석에서, TABP와 사회적인 통제와의 연관을 보면 남자 농촌 출신자에서 부모의 사회적인 지위가 낮은 군에서 비차비가 2.49, 사회경제적인 지위가 높은 군에서는 0.40의 비차비를 보였다. 여자 농촌 출신자에서는 사회경제적인 지위가 낮은 군에서 1.02, 높은 군이 0.35의 비차비를 나타내었다. 남자 도시 출신자에서 낮은 사회경제적인 군에서 1.27, 높은 군에서 1.29의 비차비를 나타내었고, 여자에서는 높은 지위군이 0.85, 낮은 지위 군이 0.67였다. 층화분석시에 95% 신뢰구간에 1을 포함하지 않아서 통계적인 유의성을 보였던 비차비는 없었다. 출신지별로 본 다중지수형회귀분석에서 농촌 출신자에서는 부모의 사회경제적인 지위와 사회적인 통제의 상호작용항이 통계적으로 유의한 3.99의 비차비(95% CI, $1.03{\sim}15.46$)를 보였을 뿐이며, 도시 출신자에서는 통계적으로 유의한 변수는 없었다. 이러한 결과는 한국에서의 사회적인 불이익집단인 농촌 출신자들의 교육에 의한 사회적인 상류층으로의 이동과 전통적인 유교 사회에서의 학업의 성취가 유교적인 선의 하나로 인식되고 있음을 반영해 주는 것으로 한국에서의 A형행동양상은 서구와는 다른 사회문화적인 구조에서 유래한다고 볼 수 있을 것이다.

지속적인 암환자 및 암 관련 의료비용 급증은 환자 개인의 고통 및 경제적 부담으로 작용할 뿐만아니라 사회적인 부담이 되고 있다. 이에 재가암 환자에 대한 통증관리 등의 서비스 제공은 의료 비용을 절감하는데 효과가 있을 것으로 여겨지고 있다. 따라서 재가암환자에 대한 적절한 의료 및 복지 서비스 등을 제공하기 위한 자료로 활용하고자 재가암환자관리사업 수혜자의 서비스 요구도에 대하여 각 보건소의 재가암환자관리사업 담당자가 재가암환자관리사업 수혜자 방문시 면접조사방법으로 조사하였고, 불충분응답자 15명을 제외한 661명을 최종 분석대상으로 하였다. 재가암환자의 서비스 요구도에 대한 요인분석 결과 5가지 영역으로 분류할 수 있었고, 요인별 신뢰도는 0.593~0.890이었다. 요구도의 순위는 사회적 지지, 정보 및 교육제공, 심리적 문제해결, 신체증상해결, 가사도움 순으로 조사되었다. 대상자를 암 치료 및 진행 정도에 따라 말기암 환자, 치료중인 암환자, 암 완치자로 분류하였을 때, 말기암환자의 요구도가 가장 높게 나타났으며, 사회적지지, 심리적 문제 해결, 정보 및 교육 순서로 요구도가 높았다. 나머지 그룹에서는 사회적지지, 정보 및 교육, 심리적 문제 해결 순으로 말기 암환자와 차이를 보였다. 뿐만 아니라, 연령별, 거주 지역별, 종교 유무에 따른 서비스 요구도에 차이가 관찰되었고, 이를 바탕으로 현재 제공되고 있는 재가암환자관리의 효율적인 추진을 위해 대상자 분류, 연령별 및 거주 지역별 특성에 따른 서비스가 제공될 수 있도록 해야 할 것이다.
