The total population of Korea in 1975 was 35,281,000 and population density was $357/km^2$, which is one of the highest rate of the countries in the world. In the early part of 1960's, prior to the initiation of national family planning program in 1962, the natural population increase rate in Korea was almost 3.0%. However, due to the positive support and activity of the national family planning program, the population growth rate has been dropped right below 2.0% in 1970, and decreased to 1.7% in 1975. The average number of children per woman was 5.8 in 1961 and has decreased steadily to 3.5 in 1975. However, traditional value like the 'boy-preference' concept may bring many difficulties of lowering the fertility rate, decreasing number of children less than three in the future. Rising marriage age which had much contributed to decrease the population growth showed preferably falling trends since 1970. There is a prospect that total number of birth will be continuously increased while the fertility rate may be fallen since the age group born during 'baby-boom' soon after the Korean war are becoming the reproductive age group at present time. Considering the above mentioned factors, family planning program should be much improved and strengthened and the government support is much required in order to meet the above mentioned objectives which maintain appropriate level of the population growth.

The purpose of this study was to empirically describe the everyday life of middle-aged adults in terms of their time-use activities. From the original '2004 Time dairy' Data, developed by the Korean National Statistical Office (KNOS), 17,684 respondents aged between 35-59 were selected. In order to categorize their activity patterns, work/labour, domestic labour, and spare leisure time were classified according to the action classification system. As a result, four dominant types were found: namely work-leisure, work-oriented, family-oriented, and leisure-oriented activities. Results of multinomial logistic analysis revealed that gender, age, socioeconomic status, job characteristic, and family structure were the major determinants on time-use. Compared with work-leisure, young middle aged women holding a part-time job with less income tended to be involved in a family-centered time use. Dual earners with lower SES status were likely to have work-oriented time schedules. Older men with relatively lower income were more likely to be involved in leisure-oriented activities rather than work-leisure activities. Multitasking behavior was a significant variable in explaining the four different types of time-use. Work-oriented group showed the highest level of time pressure as well as fatigue. Group differences in these measures, however, was not as large as expected.

Sclerotinia sclerotiorum fungus has three endoxylanases induced by wheat bran. In the first part, a partial xylanase sequence gene (90 bp) was isolated by PCR corresponding to catalytic domains (${\beta}5$ and ${\beta}6$ strands of this protein). The high homology of this sequence with xylanase of Botryotinia fuckeliana has permitted in the second part to amplify the XYN1 gene. Sequence analysis of DNA and cDNA revealed an ORF of 746 bp interrupted by a 65 bp intron, thus encoding a predicted protein of 226 amino acids. The mature enzyme (20.06 kDa), is coded by 188 amino acid (pI 9.26). XYN1 belongs to G/11 glycosyl hydrolases family with a conserved catalytic domain containing $E_{86}$ and $E_{178}$ residues. Bioinformatics analysis revealed that there was no Asn-X-Ser/Thr motif required for N-linked glycosylation in the deduced sequence however, five O-glycosylation sites could intervene in the different folding of xylanses isoforms and in their secretary pathway.

The purpose of this study was to analyse the factor of the variables that contributed to the ego-identity of middle-aged women. The subjects were 751 middle-aged women whose age was from 40 to 60 years old. The instruments used in the study were the assessments of ego-identity, self-differentiation, and internal systems. The data were analysed by using pearson correlation and hierarchical multiple regression. The findings were as follows; (1) In the result of the analysis about relationships with ego-identity, the ego-identity was positively correlated with self-differentiation and the self of internal systems and negatively correlated with the parts of internal systems; (2) Predictors of ego-identity of the middle-aged women ordered occupation type, the level of education, cognitive-emotional function, self integration, family projection process, self, pleasing/abandoned part, and self-harming part. Based on these results, the recommendations for the future research in this area were discussed.

This paper estimated the demand function of the cuts of Korean beef and imported beef by using the consumer panel and retail price data from the Korean Agro-Fisheries & Food Trade Corporation, and the weather data from the Korea Meteorological Administration with an log-log model and AIDS model. The results show that the preference for cuts of beef used for cooked soup, steamed dish, Changjorim are more elastic than cuts used for roasting when there is a change in price and income in the estimation of demand function of Korean beef. On the other hand, consumers respond sensitively with the demand of roasting part compared to steamed dish, Changjorim, soup when there is change in price and income in the estimation of demand function of imported beef. The results indicate that there is substitutional relationship between Korean beef and imported beef, because Korean beef cuts used for roasting can substitute for imported roasting part and the same relationship applies to steamed dish, soup, Changjorim. In addition, family number, family member, husband job, purchasing place, means of transportation, purchasing time, weather are statistically significant.

This study examined the mediation effect of the family resilience between the family stress and social problem solving ability of the women social worker and welfare specialist, considering that women's middle age needs the resilience including the adaptation, reestablishment in the family life cycle. The sampling target was the 328 women social workers in the middle age, and it performed the Sobel Test for the mediation effect verification after enforcing the multiple regression analysis, next, it is same. Firstly, the economic problem was most highly severe among the family stress subfactor. Secondly, there was altogether the part mediation effect of the family resilience' subfactors, ie, communication processes, belief systems and organizational patterns between the family stress and social problem solving ability. In conclusion, if the family stress which the middle aged women social worker confronted was accurately analyzed and the family is intervened so that the family resilience functions properly, the social problem solving ability would be able to be improved.

In order to discriminate the morphologically analogous smallscale blackfish, Girella leonina and largescale blackfish, G. punctata, various methods were used by using biometric and geometric approaches. Morphometric analysis showed considerable 19 differences of total 44 morphometric dimensions: classical dimension 1 part; truss dimension 12 parts; and head part dimension 6 parts (P < 0.05). Some differences of morphological features primarily involved in caudal part of truss dimension. Our results of this study confirmed that two species adequately can distinguish with external body shape, and we hope that the results of our study could be used to identify in Girellidae family as taxonomical parameters.

We examine how women entrepreneurs in contents business experience work/family role conflict and then reveal what kind of conflict management strategies they adopt in varying external and internal conditions. A critical problem faced by female entrepreneur is the tension that exists between their personal lives and business role. This tension is viewed as a form of inter-role conflict in which the role pressure from work and family competes for women's limited time and energy. First, we probe the content and nature of work- family role conflict on the part of female entrepreneurs. Second, we closely look at the three strategies of work/family role manipulation. Family role reduction strategy, work role reduction strategy, and work/family role sharing strategy are identified. Third, we discuss how the choice of the three strategies is affected by internal family salience and the external resources including spouse, family, and financial resources.

The aim of this research was to investigate how a family forest education program can improve communication skills, parenting efficacy, and family strengths. For this study, 165 people answered survey questions. The sample group included 103 parents, and 62 children, all of which were family forest education program participants at the National Center for Forest Education, in Hoengseong, Korea. Surveys were conducted before and after participants had taken part in the program. Demographic information, motivation, satisfaction, communication skills,and parenting efficacy were investigated in the surveys. The results showed a statistically significant increase in the level of family strengths of parents and children after the program. Moreover, the program improved parenting efficacy, and parent-child communication skills, which are deeply related to family strengths. In other words, the family forest education program contributed to the enhancement of family strengths. This study verifies the need for continued research in forest education programs.
