        This study was performed to investigate the quality characteristics for using as processing food by steaming and canning treatment of sea urchin (A. crassispina, P. depressus, H. pulcherrimus) roe. The chemical composition of A. crassispina and P. depressus roe was similar but H. pulcherrimus roe showed some differences. Composition changes by steaming and canning were not great. Can products of sea urchin roe was safe microbiologically during storage 72 hr. In the case of steaming treatment sample, pH was slight changed, salinity and sugar contents were decreased. Changes in color values of steaming and canning sample were remarkable in H. pulcherrimus roe. In hardness measurement, A. crassispina roe showed the highest value among raw samples, and P. depressus roe showed the highest value after steaming treatment.

        Objective : This study was conducted to evaluate the Job stress among workers by tasks. Methods and Material : This is a cross-sectional study consisting of self-administered qestionnaire survey. These study subjects were 983 persons in total; elementary school teachers 282, taxi-drivers 72, container terminal workers 199 and hair dressers 430. Through the questionnaire, socio-demographic characteristics, stress-related behaviors and daily sleeping hours were surveyed, and through the JCQ(Job Content Questionnaire), Job characteristic scores were assessed and through the PWI(Psychological Well being Index), psychosocial distress level was assessed. Results : Psychological job demand and decision latitude by hairdressers were the highest among 4 jobs. So, in the job strain levels, the rate of between active group and high strain group was higher than of other jobs. On taxi-drivers, psychological job demand was high in some degree but decision latitude and social support were low. In case of contain terminal workers, psychological job demand and social support were high in some degree but decision latitude was the lowest among 4. On elementary school teachers, social support was high in some degree. but decision latitude was low and psychological job demand was lowest among 4. Accordingly, in Job strain, the rate of passive group was the highest, but the rate of high strain group was the lowest. On hairdressers, the job strain by each rank was very various; in case of staff, the rate of passive group and high strain group was the highest and in case of designers and directors, the rate of active group and strain group was high(P<0.01). The psychosocial distress of taxi-drivers(PWI; 90.1) and container terminal workers(PWI; 88.3) were very serious. It was thought that the common job characteristics caused works by turns, night workers, irregular break and mealtime, and strain against accidents as job stressors. Only on hairdressers, the difference of PWI levels by each rand was statistically significant; staffs(46.9) and designers(44.9) were higher than directors(34.8)(P<0.01). Comparing the results of PWI between low strain group and high strain group, only about hairdressers, the PWI was high(P=0.0001) and high strain group odds ratio about low strain group was statistically significant. Conclusion : It could be evaluated the job stress among workers by tasks. To lower the job strain levels and to raise the rate of active group in container terminal workers and elementary school teachers, the decision latitude should be guaranteed. On taxi-drivers and hairdressers, social support should be consolidated. Especially to decrease psychosocial distress among workers, an effective and systematic job stress management programs should be needed.

        임신간격에 관한 분석연구 : 한국농촌 일가 임여성을 대상으로

        이승욱,김정근 한국보건통계학회 1976 한국보건정보통계학회지 Vol.2 No.1

        This is one part of "Community Pregnancy Study" which has been carried out at three Myons of Chunseong Gun area, Kangwon Province over the period covering from May 1973 to April 1976 with financial assistance from UNFPA. In order to increase the sample size the author has included retrospective information for the period from May 1971 through April 1973. Among the three Myons where the study was actually done, one Myon, called Shindong Myon, has been a demonstration area of the Community Health Program by the School of public Health, Seoul National University since 1972. The intensive health care program is being carried out there for the purpose of field training for students, demonstration model for comprehensive health services, and health research activities. In the present analysis, the pregnancy interval is defined as the period between the end of a certain pregnancy and the beginning of next one, and is assumed to be made of two components: Ⅰ) Infecundable period including post·partum amenorrhoea and anovulatory period, Ⅱ) Fecundable period including ovulatory period. Since the pregnancy interval is the elementary basis for the enhancement of MCH, the author attempted to analyze from these data how the types of previous pregnancy terminations affected the following closed pregnancy intervals. This study attempted to compare by Myons Ⅰ) how the family planning programs prolong pregnancy intervals, Ⅱ) the differences among different types of previous pregnancy terminations, and Ⅲ) the impact of pregnancy interval to MCH. The results are summarized as follows. Ⅰ. The number born between 1935-1954 amounted to 655(91.9%) in total, which is reasonable when compared with the distribution of the married women of child-bearing age in general (Table 1). Ⅱ. By the number of women 543(76.4%) experienced one interval, 149(20.7%) two, and others over three (Table 2). Ⅲ. There were 912 cases in total and among them 735(80. 6%) did not practice contraception during the interval (Table 3). Ⅳ.The increase in the number of living children resulted in the lengthening of the pregnancy interval regardless of contraception (Table 4). Ⅴ. The mean of all the intervals was 20.8 months with the use of contraception and 13.4 without it (Table 5). Ⅵ. The pregnancy interval after live birth was 23.3 months with the use of contraception, and 6.3 without it (Table 5). Ⅶ. The interval after fetal death was 13.7 months with contraception and 6. 3 without it. Also the interval after spontaneous abortion was 11. 6 with contraception and 6. 1 without it after induced abortion 14. 5 with contraception and 6. 4 without it (Table 5). Ⅷ. It was observed that as the mothers' age at the beginning & end of interval increased, so did the length of interval regardless of contraception (Table 6). Ⅸ. The regression & correlation analyses were performed on the pregnancy interval by the mothers' age as shown in the end of Chapter Ⅲ. The findings from the results are as follows; Ⅰ. When the contraception is used, the pregnancy interval after live birth is very similar to the one medically recommended. Ⅱ. The longer pregnancy intervals are observed for the higher brackets of mothers' age. Ⅲ. The experience of contraception prolonged the pregnancy interval by 7. 4 months. Ⅳ. It may be desirable to concentrate on the practice of contraception, which is found to be very effective method of family planning, rather than the induced abortions.
