The purpose of this study was to examine the relative influences of variables that affect baby boomers' perceptions and preparations for later life planning. An age-group comparison was made to examine differences in later life planning within baby boomers. 814 respondents were selected from The National Survey of Korean Families undertaken by the Ministry of Equality and Family in 2010. They were devided into two groups according to the year of their birth, the former baby boomers was 397 respondents who was born from 1955 to 1959, and the latter baby boomers was 417 respondents who was born from 1960 to 1963. The major results of this study were as follows: First, the former baby boomers was less likely to prepare for later life, while was more likely to be aware of their later life planning than the latter baby boomers. Second, educational attainment and the number of children affected the level of perceptions and preparations for later life planning of the former baby boomers, whereas sex and region affected those of the latter baby boomers. Third, household income and subjective awareness of economic status were the major determinants of the preparation level for later life by both the former and the latter baby boomers. Fourth, former baby boomers who had greater awareness of the need to support their parents and their children were more likely to prepare for later life. Fifth, baby boomers' subjective awareness of their economic status chiefly explained the gap between their level of perceptions and their preparation for later life, with the former baby boomers with more children and single-earner households more likely to show a gap between their level of needs and their preparation for later life.

The purpose of this study was to analyze the in-home child care support service experience of twenty child rearing families. In order to conduct this study, grounded theory method was employed. The central phenomenon of the service experience digged out from this study was 'difficulty' (i. e. insecurity and a feeling of helplessness). The causal conditions which brought about the central phenomenon were 'defect of system' and 'service characteristics' The intervening conditions included 'alternative resources' 'working conditions' and 'service institute manager discretion'. The contextual conditions consisted of 'maternal ideology' 'the public nanny's personality awareness'. The action/interaction strategies on the central phenomenon were 'inaction' 'insecurity decrease strategy' and 'dissonance decrease strategy. The final outcome was 'rearing gap fillup "the method of nanny managing" dissatisfaction accumulation' ''system improvement demand'. The families were classified as four types: 'management/subject' 'adaptation/dependent' 'patience/acceptant' 'supplementation/overcoming'. Based on these results, this study provided a few political and practice suggestions to improve this system.

This essay has attempted to document the actual behavior patterns and the social networks related to the child delivery in the pre-industrial Korean society. We interviewed 30 women who had given birth to their first child during the 1930s and the 1940s in order to accumulate data related to son-prayer rites, prenatal care and food avoidance, sacred-string culture, and other incantation rituals. The characteristics of the social relationships with the person who had assisted the delivery and the recovery were also analyzed in terms of kinship networks. The results are as follows. First, there was a big gap between knowledge and the actual practices in birth rituals and customs. We assume that this is due to the adverse social-economic conditions at that time which may have restricted the actual performances of these customs. Second, there were almost no differences of the performance of these' birth customs between the urban areas and the rural areas. Third, the people who assisted the delivery were women who were mostly from the husband's family. Help from the wife's family were quite exceptional. Finally, it has been found out that only about half of the women who were interviewed performed the well-known custom of three-week after-birth confinement.

PCR-mediated recombination describes the process of in vitro chimera formation from related template sequences present in a single PCR amplification. The high levels of genetic redundancy in eukaryotic genomes should make recombination artifacts occur readily. However, few evolutionary biologists adequately consider this phenomenon when studying gene lineages. The cytosolic glyceraldehyde-3-phosphate dehydrogenase gene (GapC), which encodes a NADP-dependent nonphosphorylating glyceraldehyde-3-phosphate dehydrogenase in the cytosol, is a classical lowcopy nuclear gene marker and is commonly used in molecular evolutionary studies. Here, we report on the occurrence of PCR-mediated recombination in the GapC gene family of Hibiscus tiliaceus. The study suggests that recombinant areas appear to be correlated with DNA template secondary structures. Our observations highlight that recombination artifacts should be considered when studying specific and allelic phylogenies. The authors suggest that nested PCR be used to suppress PCRmediated recombination.

A new constitutive episomal expression vector, pGAPZ-E, was constructed and used for initial screening of eukaryotic target gene expression in Pichia pastoris. Two reporter genes such as beta-galactosidase gene and GFPuv gene were overexpressed in P. pastoris. The expression level of the episomal pGAPZ-E strain was higher than that of the integrated form when the beta-galactosidase gene was used as the reporter gene in P. pastoris X33. The avoiding of both the integration procedure and an induction step simplified the overall screening process for eukaryotic target gene expression in P. pastoris. Nine human protein targets from the Core 50, family of Northeast Structural Genomics Consortium (http://www.nesg.org), which were intractable when expressed in E. coli, were subjected to rapid screening for soluble expression in P. pastoris. HR547, HR919, and HR1697 human proteins, which had previously been found to express poorly or to be insoluble in E. coli, expressed in soluble form in P. pastoris. Therefore, the new episomal GAP promoter vector provides a convenient and alternative system for high-throughput screening of eukaryotic protein expression in P. pastoris.

Korean is well-known for its topic-prominent properties. In this paper, we look into several subtypes of topic constructions whose grammatical complexities have received much attention in generative grammar. From a semantic/pragmatic view, topics in Korean can be classified into three different types: aboutness, contrastive, and scene-setting. Meanwhile, syntax can classify topic constructions into two types, depending on whether or not the comment clause following topic has a syntactic gap linked to the topic. In this paper, we review some key properties of these topic constructions in Korean, and suggest that each type is licensed by tight interactions between syntactic and semantic constraints. In particular, the paper tries to offer a Construction Grammar analysis where each grammatical component is interacting in non-modular ways and in which the multiple inheritance network of constructions plays an important role in capturing cross-cutting generalizations of the topic constructions.

This paper is concerned with the family of parts that generally feature a central hub with radial protrusions. As opposed to conventional forward and backward extrusion, in which the material flows in a direction parallel to that of the punch or die motion, the material flows perpendicular to the punch motion in radial extrusion. Three variants of radial extrusion of a collar or flange are investigated. Case I involves forcing a cylindrical billet against a flat die, Case II involves deformation against a stationary punch recessed in the lower die, and Case III involves both the upper and lower punches moving together toward the center of the billet. Extensive simulational work is performed with each case to see the process conditions in terms of forging load, balanced and symmetrical flow in the flange. Also, the effect of the gap size and die corner radii to the material flow are investigated. In this study, the forming characteristics of radial extrusion will be considered by comparing the forces, shapes etc. The design factors during radial extrusion are investigated by the rigid-plastic FEM simulation.

The purpose of this study was to understand family changes and dynamics of and to suggest institutional/policy-level tasks for coping with them, by paying attention to changing family values of single-person households and their caring work performed in everyday life. This study selected 11 single-person households residing in Ulsan by considering their age and marital status, and analyzed their overall daily lives, family values, and the characteristics of household work and caring. The characteristics of these single-person households in Ulsan, not only showed the coexistence of "simplicity, but instability" when maintaining and living their own lives, but also showed the ambivalent characteristics of family values by showing a gap between the perception and reality of diversity. In regard to family life, the participants complained of difficulties in "caring and relationship of family of origin" and the "economic factors", and notably showed the "dual value system". For a more stable life, the single-person households were forming social networks to relieve a sense of isolation and loneliness, and to recover relationships, instead of limiting themselves to only the traditional method of family formation. Thus, it would be possible to respond to family changes when changes are promoted in each area of "the perception of life", "family life", and the "family & social relationship", and this research suggests policy-level tasks based on the results of this study.

The study, published in the 2007 revised curriculum of Practical Arts and Technology and Home Economics textbook(16 species) of the 'human development and family members' area of learning content elements were analyzed. This analysis was conducted in order to evaluate that the 2007 revised curriculum of Practical Arts(Technology and Home Economics) has been made well Articulations. The criteria of Articulations is "Development of learning content, Repeating, Gaps, Reduction. Content criterias is 'human development and family' area. These include "human development, human relationships, marriage and family life, caring for family members and family welfare" of the four criteria and 14 content elements. The results of this analysis, the first content elements is "process of human development, characteristics of human development, family relationships, communication, dating and partner selection, the significance of marriage and family, understanding the basic concepts of family, family change and family problem solving". There was no content elements. content element is 'friendship'. content elements is 'Characteristics of human development', 'understanding of sex and pregnancy and childbirth'. Thus, in the new curriculum, a review of these Articulations are required. Especially, the 'friendship' and 'understanding of sex and pregnancy and childbirth' of the content element should be noted in the curriculum configuration because of content elements be Analyzed as or . Also 'values about marriage change' importance in the low fertility society is a big learning content elements need repeating. However, textbooks should reflect differences in the configuration will hakgyogeupgan. Meanwhile, 'changes in values about marriage' that it is necessary to deal with the repeatedly because of recentely society is The low fertility society, However, for this content element based on the differences between school level to appear the contents of textbooks, the textbook screening process will be provided with the correct guidance.

The purpose of this study was to examine a path model that investigated the relations among socioeconomic variables. financial management and financial satisfaction of urban households. for this purpose conceptual framework based on the system theory of family resource management was suggested. Data were collected from questionaire with 254 financial managers who were residents of Seoul. The major findings of this study were as follows: (1) The variables that effected financial satisfaction directly ere financial knowledge monthly saving amounts the gap between the level and standard of living and financial implementing. The financial planning effected indirectly on financial satsfaction through financial implementing. (2) The findings of this study provided support for a systems approach to family financial management. There result indicated that it is the combined effect of inputs and throughputs that effects the output of financial satisfaction.
