This paper investigates effects of family size on private tutoring expenditures, using a data set drawn from the Korean Longitudinal Survey of Women & Families (KLoWF). To deal with endogeneity of family size, the paper employs an instrumental variable (IV) method in which the sex of the first-born of the family is used as an IV. The results suggest that quantity-quality trade-offs of children within a family function in a way that varies by the sex of the child. While the effect of an increase in family size on private turoring expenditures of a second-born daughter is negative, the effect for a second-born son is indeterminate. The result for daughters implies that high costs of raising a child are likely to explain low birth rates of Korea.

Korean family planning program has been adopted as a part of the Economic Development Plan with strong national government backup. After initiation of family planning program, the increase rate of total population declined from 2.6 percent during 1955-1960, to 2.1 percent in 1960-1975, and 1.6 percent in 1979. Of course, we do not ascribe this population increase rate decline to the national family planning program alone. Other contributing factors have been changes such as growing numbers of induced absortions, a rising marriage age and economic development. Currently, 2,600 family planning workers are assigned in all myun of the country. 21 percent of the works are registered nurse, 9 percent are midwife and aid nurses occupy 70 percent (Table 1). Authorized clinics are 2,329 which composed 1,765 IUD clinics, 1,070 vasectomy clinics and 1,150 Fimale sterilization clinics (Table 2). Cumulative contraceptive services provided by government program, 1962-1974 is illustrated in Table 3. After government program in family planning has been initiated (1962-1978), estimated number of births averted by each methods was measured (Table 4). From 1962 to 1978, tendency of contraceptive acceptors is illustrated in Table 5 showed that IUD, oral pill and condom program is decreasing and in other hand, sterilization program is increasing very much. Attitude change toward family size (1965-1978), contraceptive practice and son preference are showed in Table 7, 8, respectively. Auther concluded that future program in family planning should target to the point, that smaller family size norm for maternal health should be emphasized rather than smaller size family for national development.

In this survey, we tried to find out number of participating and main purpose of that "Kye" meeting of all family members in rural community. Main purpose is follows; First, Differences by rural area, number of participating and main purpose of that "Kye" meeting of all family members in rural community. Second, Relationship between residence years by the head of a family and numbers in rural community. Third, Relationship between size of owned land(paddy field and uplaned) by the head of a family and number of participating and main purpose of that "Kye" meeting of all family members in rural community. Fourth, Relationship between size of cultivated land(paddy field and uplaned) by the head of a family and number of participating and main purpose of that "Kye" meeting of all family memebers in rural community. The main results are as follows; First, there are different points by the kind of rural area in number of participating and "Kye for friendly gathering", "Kye for saving", "Kye for sightseeing". Second, variable of residence years of the head of a family is only negative influential factor in "Kye for saving". Third, variable of size of owned land is positive influential factor in total number of participating "Kye", "Kye for friendly gathering", "Kye for saving" and "Kye for sightseeing". Fourth, variable of size fo cultivated land is positive influential factor in total number of participating "Kye", "Kye for mournig and marriage", "Kye for friendly gatiering", "Kye for saving" and "Kye for sightseeing". It seems that "Kye" meetings are still a preferred means by the jrural community to gather the cooperation among rural population. But the purpose of "Kye" meetings has changed from the family centered such as worship or marriage and mouring of family members to out of the family centered events such as friendly gathering, sightseeing.

This study tried to develop the theoretical backgrounds, explaining consumers energy consumption behavior and analyzed its effects. In other words, this study investigated the factors influencing the amount of electronic energy consumption. In this study, we used 678 questionnaires which were selected a quota sampling by living area who were above 20 years old and married. Summary of results of this study follows. First, attitude for energy saving was positively related with female, high school graduated large size of family members, elderly, and middle-class consumers. In addition, consumers' search for energy saving were appeared passively in young consumers under 30 years old, and the family with the highest household income. Consumers' purchasing energy-efficient products was presented in large size of family members, and young consumers. Second, consumers' environmental oriented behavior, action-directed behavior, healthseeking behavior were significantly related with energy saving behavior, and active information search for energy saving, but not with purchasing energy-efficient products and consuming behavior of electrical energy. Third, the quantity of electric energy consumption was affected by the size of family members, the living size of house related with high energy demand, the attitude for energy saving, and searching information for energy-saving.

The purpose of this study is to examine a potential association between community factors and the establishment of Local Healthy Family Support Centers (LHFSCs). Community factors were population size, community size, local finance independency, number of workplaces per 1,000 people, number of colleges, political party affiliation of mayor, and political party affiliation of congressman. Data of this study were collected from the census indicators of 222 communities from 2004 to 2014 and analyzed by frequency, mean, geographical information system mapping, and the binary logit analysis. The results of this study are as follows. First, LHFSCs are less likely to be established in communities in the provinces of Gangwon, Chungbuk, and Gyeongbuk. Second, the population size was positively related to the establishment of LHFSCs. Third, finance independency was positively associated with the establishment of LHFSCs. Forth, a mayor was more likely to establish LHFSCs if they were affiliated with the ruling conservative political party. However, the establishment of LHFSCs was not affected by other factors such as community scale, number of workplaces per 1,000 people, the number of colleges, and party affiliation of congressman. Thus, the conclusion suggests family policy implications to improve the geographical imbalance of LHFSCs based on the analysis results.

Genetic gains and inbreeding coefficients in a Holstein MOET breeding population were predicted under different conditions relating to the distribution of the number of transferable embryos collected per flush using Monte Carlo simulation. The numbers of transferable embryos collected per flush were determined using five distributions (distributions 1, 3, 5, 7 and 9) with different aspects and similar means. Distributions 1, 3, 5, 7 and 9 were assumed to have gamma distribution's parameters ($\alpha$ and $\beta$) of (1 and 4.4), (3 and 1.47), (5 and 0.88), (7 and 0.63) and (9 and 0.49), respectively. Inbreeding rates were statistically significantly different among distributions but genetic gains were not. Relationships between inbreeding rates and variances of family size could be were clearly distinguished. The highest inbreeding coefficients were predicted in distribution 1 with the largest variance of family size, while distributions 5, 7 and 9 with smaller variance of family size had lower inbreeding coefficients.

The main objective of this study was to examine the effects of family-friendly culture in various organizations in the private sectors on employee self-reported work-family balance and qualities of lives. It also attempted to clarify whether employee perceived work-family culture would vary according to size and type of organization, gender, and dual career partnership. The data came from 365 married full-time workers employed in a wide variety of organizations located in Seoul and GyeongGi-Do. The major findings of this study were as follows: Work-family culture was perceived more family-friendly in large-sized organizations and consumer industries. Female employees and workers in dual-career partnerships perceived the work-family culture of their organizations less family-friendly. The hierarchical multiple regression analyses revealed that firm size, supervisory support for employees' family activities, and the perception of negative career development opportunities as a consequence of utilizing family-friendly policies significantly predicted employees' work-family balance and qualities of lives, while organizational time demands having no significant effects on them. The implications of study results were discussed.

Recently, during several years the number of ideal children have not changed at all. Because the most of Korean people considered that son is necessary absolutely for dependence in old age inheritance of family line and holding ritural and so on. Threfore, without revolution of value system for children we could no more expect to reduce fertility rate. The survey is intended to compare the characteristics between those women who want two or less number of ideal children and all married women(regardless the number of ideal children). The results showed as follows: The women who want small size of family were younger and little better educated than those of all married women. The age at marriage of women who want small size of family was older than that of all married women. The conducted rate of induced abortion and acceptance rate of contraception among those women who want small size of family were higher than those of all married women.
