Objectives: This study aimed to evaluate whether the birth rate is associated with socioeconomic status in the women of the Republic of Korea, where the birth rate is rapidly decreasing. Methods: This study included 732 females from the Healthy Twin Study, a family-twin cohort. The participants were classified into 3 socioeconomic groups according to their average income, education, and occupation. The association between socioeconomic status and number of children was assessed using gamma regression analysis with a generalized linear mixed model, adjusting for the age group, smoking/alcohol status, and family relationships. Results: The group with the highest education level had significantly fewer children compared with the group with the lowest education level (p=0.004). However, no significant associations were found according to household income level. The non-manual labor group had significantly fewer children compared with those working as homemakers (p=0.008). Conclusions: This study aimed to explain the causal relationship between socioeconomic status and number of children. Associations between some socioeconomic status and number of children were found in Korea.

This study was conducted to investigate and to compare the health status of urban and rural elderly in Korea using the following factors: 1) the number of self-reported health problems 2) a self-rating score for health status 3) the number of diagnosed diseases 4) ADL, social health status by IADL and the psychological health status by Life Satisfaction scale developed by Wood and others. The study subjects were the elderly who lived in Pusan(N=150) as an urban area and Kyeungnam(N=300) province as a rural area. The study subjects were sampled at random and the data were collected by trained interviewers from Feb. 1 to Feb. 14, 1995. the data was analyzed in SPSS. The results can be summarized as follows : 1. According to the sociodemographic characteristics of the subjects, the urban elderly group was significantly higher in extended family groups and in practicing regular execise than the rural elderly: and the rural elderly group was higher in having spouses and occupations than the urban group. 2. Concerning health status, the numbers of self-reported health problems(eye problems, back pains, headaches, dental problems, arthritis) and number of diagnosed diseases(hypertension, heart problems, diabetes mellitus, neuralgia, arthritis) were significantly were higher higher in rural areas: the self - rating scores for health status and life satisfaction were higher urban areas. ADL and IADL were similar in both the rural and urban elderly. 3. The correlations were the following: Self-reported health problems and self-rating for health status were significantly correlated negatively(r=-.039, p=.000), but self-reported health problems and the number of diagnosed diseases were significantly positively correlated(r=0. 30, p=.000). IADL and health problems were negatively correlated(r=-0.16, p=.000), but IADL and ADL were significantly positively correlated (r=0.49, p=.000). Life satisfaction and self-rating scores for health status were significantly positively correlated(r=0.26, p=.000).

According to seventh curriculum, new types of school design have been developed recently. However there are hardly any data of national status about plan and area organization, types and number of rooms of those. On this background, the purpose of this study is to provide fundamental resources for architectural designing and planning of high schools and to recognize national status of plan organizations of high schools through collecting 53 school's standard design drawings(arrangement, plan drawing) which city, province education office drafted for 4 years(from 1997 to 2000) and analyzing them into plan types, building area and type, number and area of rooms. The results of this study are as follows: 1. The range of class number of designed 53 high schools varies from 24 to 36 and 36-class-schools are 47.2% of all. Average number of class is 34.1. As a result we can find out large scale schools are mainly designed. 2. Among 53 schools, 21 schools have the department system but few of them equipped sufficient rooms and their features are very manifold. After recognizing utilization status of each schools, the standards of room type, number and plan organization should be proposed. In terms of plan type for fluent level based transferring class, most of schools are not apt. 3. In the status of type and number of rooms related to class number, range is very wide. So simplification is necessary. 4. The variations of building area, area per a class and area per a student are very large so that standard of adequate area should be established. 5. That every school which has different plan organization from conventional schools exceeds ministry of education's minimum area standards shows those standards cannot cover the diverse plan design of school. So more adequate standards should be proposed. 6. Area and number of Teacher's research room and Home Base are also very manifold from school to school. They are also considered to be simplified immediately.

Factors indicating culture status of two Spirulina platensis strains were monitored in a batch mode cultivation for 36 days. Changing mode in all factors showed a common turning point, indicating shift of cell or culture status. Mean biomass productivity was highly sustained until day 22, chlorophyll a concentration peaked on day 22, pH value was > 12 on day 22, coil number was abruptly shortened on day 22, and floating activity was sustained at greater than 79% after day 22, indicating that day 22 is a criterion reflecting phase-transfer in cell physiology in a batch culture system. Many of these changes may have been caused by increased pH, suggesting that pH control is essential for mass production of S. platensis. Fluctuations in floating activity were likely induced by the number of cellular gas vacuoles. Consequently, coil number per trichome and floating activity of S. platensis could readily act as simple indicators for determination of culture status or harvesting time of cells.

Objectives: This study aimed to validate the moderating effect of oral health on the relationship between perceived health status and health-related quality of life in the elderly and to use this information as primary data to suggest oral health policies for the aged society. Methods: This study included 3,707 subjects aged over 65 years who answered all the variables used in the study model and completed the health questionnaire and screening survey based on the sixth Korea National Health and Nutrition Examination Survey. Baron & Kenny's linear regression analysis using SPSS 22.0 and SPSS Macro Version 3.1 programs was performed to confirm the moderating effect of the number of remaining natural teeth, chewing difficulty, and cardiovascular disease on the relationship between perceived health status and healthrelated quality of life in the elderly. Results: The number of remaining natural teeth, chewing difficulties, and cardiovascular diseases affected the perceived health status of the elderly. As the number of remaining natural teeth increased, the effect of perceived health status on the quality of life in the elderly was buffered. The effect of perceived health status on the quality of life increased with chewing difficulties and the number of cardiovascular diseases. In particular, it was confirmed that chewing difficulties, rather than the number of cardiovascular diseases. had a greater effect on the quality of life in the elderly. Conclusions: Oral health policies and projects are required to ensure oral rehabilitation with dentures and implants and restore chewing function to improve the quality of life of the elderly in Korea.

This paper shows survey result on safety management status of laboratories in Korea. In Korea, many studies and reports on laboratory safety have been published since the ministry of education, science and technology (MEST) enforced the Act on Establishing a Safe Environment of Laboratories (Lab Safety Act) in 2006. The MEST has surveyed status of safety management in institutions subject to Lab Safety Act in 2008 and 2010. According to the survey result, safety management status of universities and colleges has been improved on several factors such as establishment of safety manual and implementation of safety inspection; while the number of safety managers of universities and colleges have increased. However, the difficulties in performing duties of safety managers has increased because the number of exclusive safety managers has decreased. This paper identifies the similarities and differences between Occupational Safety and Health Act and Lab Safety Act on assignment and duties of safety managers; therefore, this paper suggests a standard to determine the number of safety managers and decide whether or not their duties should be exclusive. Besides current standard that is based on the number of researchers, the number of individual laboratories should be considered. The new method would be helpful to determine the number of exclusive safety managers because the amount of safety managers' duties generally do not depend on only the number of people who may be exposed to any risk but also the number of facilities that may be cause of any accident.

The purpose of this study is to investigate the relationship between the level of stress recognition of urban housewife and the method of coping, and to explore bow these factors are influenced by socio-demographic variables such as the age of housewife, level of education, status of employment, number of children, durations of marriage, types of family, religion and socio-economic status. The research was conducted on 431 housewives in Seoul in August, 1985. As for the measurement of the instrument, 48 item questionnaire made by investigator was used. The questionnaire was based upon modified and upplemented Holme & Rahe's SRRS and Bell's 18-item Questionnaire to be appropriate to Korean culture. Data were analyzed by percentage, frequency and mean, and verified significant difference by ANOVA and performed Spearman's correlation coefficient. The results of this study are as follows; 1) There is some similarity in distribution of the level of stress recognition of urban housewife. 2) the level of education and the durations of marriage have influence upon the level of stress recognition of urban housewife. In each area, there are differences among groups : age, level of education, durations of marriage, number of children and types of family in the area of education ; age, status of employment, and durations of marriage in the area of health; level of education, durations of marriage, number of children and socio-economic status in the area of finance; status of employment in the area of household work. 3) There are several methods in the method of coping to stress of housewife and the score of long-term coping method appears higher than that of short-term. 4) The level of education, number of children, religion and socio-economic status were variables to have influence on the method level of education, religion and socio- economic status were variables to have influence and in the long-term coping method level of education, number of children, religion, and socio-economic status were to have influence. 5) There is very low positive correlation between the level of stress recognition of urban housewife and the method of coping to stress( ρ=.10, P<.05). 6)In the relation between several variables in socio-demographic variables and the method to coping to stress, the lower the level of stress recognition there are negative correlation (ρ=-.28, P<.01) between religion and the method of coping and also negative correlation (ρ=-.16, P<.05) between number of children and the method of coping. There are positive correlation between socio-economic status and the method of coping.
