Much of the working population in developing countries are engaged in shift work now and the number of shift workers is not expected to decrease in the future mostly because the need for continuity of production is increasing. Therefore, the possible effects of shift work on health are of particular interest, and in fact, there have been many epidemiological studies on shift work since the first world war. However, no studies on health effects of shift work have been reported in Korea, and the existing studies in western world have arrived at quite different conclusions mainly because the conditions of work other than shift work, such as age and selection of workers, work environment, and labor conditions also influence the health of workers. This study was firstly carried out in Korea to investigate the health risks related to shift work with 2,093 female workers randomly selected from three major manufacturing industries in proportion to total number of female workers in those industries. Differences of work conditions other than shift work in this study were adjusted by multivariate analysis. Ma findings obtained from this study are as follows : 1. There were significant differences between shift and day workers in the distribution of age, type of industry, condition of noise and dust, regularity of mealtime, working position, and working duration. Shift workers tended to be younger, to have shorter working duration, to have more irregular mealtime, to work in standing position, and to work under more noisy and dusty environment than day workers. 2. Univariate analysis showed that shift work increased the Todai Health Index (THI) scores of digestive tract, respiratory tract, and mental instability symptom categories. Shift work also increased days of sickness absence and number of industrial accident per 100 workers per month. 3. Multivariate analysis that adjusted the differences of demographic, occupational and non-occupational health-related working conditions showed that digestive tract symptom and mental instability symptom scores were significantly higher in shift workers than those in day workers. Based on these study results, it is concluded that the shift work has significant effects on some psychophysiological conditions of the workers and the effects are also influenced by several other personal and working conditions.

The purpose of this study is to identify how the households invest in their children as a human capital. In addition, contributing factors to households' human capital investment was examined. The results of this study are as follows; First, Average number of children 2 children of surveyed housewives, full time housewives had more time spent for children than working counterparts. The former spent 6.8 hours a day with the latter 4.98 hour a day while both of them shared the most time in nonphysical care of their children. meanwhile, money paid for children was that full time housewife family spent 1,014,000 and a working housewife family paid 974,000. Second, In the full time housewives, total amount of time housewives spend for their children was greatly influenced by the income, the age of the youngest child, and emotional value. The housewives' educational level, life cycle, and an income were a significant impact on money investment. Total investment was influenced by the housewives' educational level, life cycle, income, and the number of children.

The purpose of this study is to compared the length of working hours and its effects on family life for Korean and Japanese full-time working couples. For this study, the survey used structured questionnaires and time diaries(one weekday and holiday), and the data were collected in the fall of 1995. A subsample of full-time working couples, 82 couples from Seoul and 79 couples from Tokyo, was used for the purpose of this study. The major findings are as follows; 1) On average, the weekday working hours of Korean husbands were longer than Japanese husbands(11 hours 31 minute, 10 hours 52 minutes a day, respectively). Wives in both countries worked almost identical lengths of time (9 hours 2 minutes in Korea and 8 hours 42 minutes in Japan). Working hours of husbands were longer than those of wives in both countries. Husbands' overtime. Almost (90%) of our Korea sample worked 6 days or 5 1/2 days per week, however the majority (69%) of our Japanese sample worked only 5 days per eek. 2) More Korean husbands and wives reported that their family life was constrained by wives working hours than their Japanese counterparts did. 3) All wives in both countries reported that the husbands long working hours has effects on quality family time. Korean wives perceived that their working hours had effects on time spent on child care, however Japanese wives perceived that their working hours affected their personal time and housework time. Korean husbands agreed with their wives working hours negatively affected their personal leisure time. Japanese husbands reported that their working hours negatively affected their sleeping time.

This was conducted to investigate the dietary assessment, food preferences, snack intake, priority order in food purchase, and knowledge of diet of full-time housewives and working housewives through the use of a questionnaire. The participants (127 working housewives and 86 housewives) were selected at random from Seoul and its vicinity. The predominant job reported by working housewives was saleswomen and specialized job (20.7%). The average monthly income of both housewives and working housewives ranged from 3,000,000 to 5,000,000 won. Forty percent of housewives consumed more meat, fish, eggs, beans, and tofu, while 50.0% of housewives ate vegetables other than kimchi at every meal, 51.2% of housewives consumed one serving of fruit and one cup of fruit juice, 45.3% of housewives consumed three regular meals, and 60.5% of housewives consumed a balanced diet when compared with working housewives (p<0.05). Working housewives consumed beverages, ice cream, milk, and dairy products, while housewives consumed breads, sweet potato, potato, and fruit as snacks. The preference that most often led to food selection was flavor among working housewives (67.7%) and housewives (64.0%). Both working housewives and housewives always confirmed the day of food production. Generally, housewives were more interested in learning about food, creating a dietary plan, nutrient loss during cooking and reducing waste food when compared with working housewives. Housewives appeared to have better dietary assessment and knowledge than working housewives. Accordingly, it is advisable to prepare more systemic education programs for working housewives.

근로시간이 단축될 경우 건설산업은 타산업과는 달리 일회성, 옥외성, 계절성 등의 특성으로 인하여 근로시간 단축으로 인한 파급효과를 단순히 작업의 총량개념으로만 접근하여 분석하기에는 어려움이 있다. 법정 근로시간 단축의 영향을 보다 정확하게 예측하기 위해서는 예상되는 비용상승 효과가 실제 건설공사 생산구조에 어떻게 받아들여질 것인가에 대한 조사와 분석이 필수적이다. 이를 위해 건설현장의 근로시간과 근로패턴에 관한 문헌조사와 일본 건설산업의 근로시간 단축 사례 조사를 수행하였으며, 결과적으로 근로시간 단축으로 인한 현장의 근로패턴 변화를 분석${\cdot}$ 예측하였다. 근로 패턴 변화는 실제 생산활동에 참여하는 현장근로자를 대상으로 년 단위 현행 모델과 근로시간 단축 후의 예측 모델을 구축하여 비교${\cdot}$분석하였으며, 현장관리 측면에서의 대처방안을 제시하였다.

건설공사에서 공정관리는 공사 기간을 결정하는 중요한 단계이나, 설계단계에서 작업불가능 일수 예측 및 산정이 제대로 이루어지지 않아 예정공기와 실행공기의 차이가 발생하고 있다. 이러한 차이를 최소화하기 위하여, 본 논문에서는 공정계획 수립 시 실제에 가장 근접하는 방법으로 추석 및 구정연휴를 휴무일에 반영한 작업불가능 일수 산정방법과, 주요공종별 특성분석을 통한 작업가능일수 산정방법을 제시하였으며, 이를 바탕으로 주요단위공종에 대한 공기산정시 작업불가능 일수가 포함된 최적의 단위공기 산정방법을 제안하였다. 같은 현장 동일공사에 대한 기존 방법과 개선된 방법의 보정계수를 적용하여 소요작업 일수를 산출한바 개선된 방법이 실작업일수 기준으로는 22일(9.1%) 단축됨을 확인하였으며, 공종별 작업소요일수 기준(안)을 수원지역 개착식 공동구 공사에 대하여 적용 전과 후의 차이를 비교하였다. 기준(안) 적용 전 공사일수는 총 304일 이었으나, 기준(안) 적용 후 공사일 수는 총 421일로 설계단계에서 공정계획의 중요성을 예로 확인하였다. 본 연구 결과는 그동안 현장에서 관행적으로 시행되어 오던 실 작업일수 계산과 공정표상 작업일수의 불일치로 인한 공정지연을 방지하고 보다 실제에 근접한 공정계획 수립에 도움이 될 것으로 판단한다.

The purpose of this study is to provide basic information for planning family day care. The purpose was accomplished by observations, interviews and survey. The total 29 family day care centers were selected for the observations. The interviews and survey were conducted with 44 caregivers working there. Data were analyzed by descriptive statistics, analysis of variance and multiple regressions. According to the findings of the study, most family day care centers in apartment unit were to keep the laws related to the locations, number of children, etc. Also, the caregivers were satisfied with the general physical conditions of the centers, while they tended to be less satisfied with the space for themselves. Finally this study suggested several design alternativesas useful guidelines for the apartment family day care center.
