This study is intended to improve parental capacity from the viewpoint of children's happiness. It extracts a core parental capacity for children's happiness from the international index such as OECD well-being, UNICEF Children's welfare, International survey of children's well-being, and Korean children's key index. Based on the extracted core parental capacity, this study developed a self-checklist aiming to perceive parents' capacity status and suggest a political plan in order to improve parents' capacity for children's happiness. The self-checklist has a total of 66 questions and is composed of 7 domains; Child development, Health and Safety, Family relation, Physical and material environment, Play, Guidance in life, and Community engagement. The results from the survey are as follows. The domains of Development of children as well as Health & Safety are reported as the highest value at 4.1 point; on the contrary, those of Guidance in life and Community engagement are reported as the lowest value at 3.8 point. In terms of age, it was reported that the capacity of parents under 35 years-old was better than that of parents over 35 years of age. As for family income, it was revealed that the order of parents' capacity generally depends on the family income.

Flour physicochemical properties of six Korean waxy wheat lines and their parental plants, including Kanto 107 and BaiHuo, which have partially null in GBSS (granule bound starch synthase), were evaluated in this study. The very low amylose content (3.20%) of Korean waxy wheat lines, which had been influenced by the null in all three GBSS isoforms encoded by three Wx loci, could result in the higher starch swelling power (25.15%), lower starch and flour pasting temperature (61.37$^{\circ}C$; 65.85$^{\circ}C$), and higher starch pasting peak viscosity and breakdown (246.60 RVU; 161.50 RVU) than those of their parental plants. In addition to high swelling and pasting properties, Korean waxy wheat lines had the higher protein content (12.80%), alkaline water retention capacity (97.39%), SDS sedimentation volume (80.33 $m\ell$) and damaged starch content (4.35 %) than those of their parental plants.

The purpose of this study is to analyze the concept of caretaking behavior for children. This study adopts the methode of Walker and Avant in analysis. Based on the results of the study, the attributes, precedents, and consequences of caretaking behavior for children are follows ; 1. The affirmative attributes of caretaking behavior are affection binding, nutritional guidance, education, caring, protection moral training and acquisition of parents' role. The negative attributes of caretaking behavior are inconsistent moral training, incapability of affection binding and overprotection. 2. The precedent of caretaking behavior are postpartum contact with their babies, cognizance capacity of child-caretaking, economic support, level of preparation for child-caretaking and self-consciousness as parents. 3. The affirmative consequences of caretaking behavior are promotion of child growth and development, formation of maternal-infantile attachment, development of children sociality, satisfaction of parental role and reinforcement of relationship between the members of family. The negative consequences of caretaking behavior are burden and conflict to parental role, children's illness, role conflict and role stress among the members of the family and family breaking up.

Purpose: This study was done to explore disease factors in children with epilepsy, parental factors and resource factors that are related to parenting stress and identify effects of each factor on parenting stress. Methods: Participants were 131 parents who had children who visited a hospital or were hospitalized due to epilepsy. Data collection was done between September 17 and November 17, 2012, and self-report surveys were used. Results: In Stepwise multiple regression analysis, factors influencing parenting stress in children with epilepsy were marital communication, educational background of parents, parenting efficacy, children's development delay, drug treatment and surgical treatment as a method of epilepsy treatment. These factors explained 34.6% (F=13.22, p<.001) of the variance in parenting stress. Conclusion: The findings indicate that parental factors (educational background of parents and parenting efficacy) and resource factors (marital communication) have higher explanatory power than disease factors of the children. Thus, it is importance to assess the capacity of parents through self-evaluation, and to assess barriers to marital communication when developing parenting stress intervention programs. Furthermore, both parents should be involved in interventions for parenting stress.

This study aimed to identify ways to implement pre-parent education for adolescents in regular classes at school. This was achieved by investigating whether the contents of the 2015 revised curriculum high-school technology and home economics textbooks reflected the goals of pre-parent education. The main texts and activities of chapters with 'preparing for parenthood' in the title from 12 high-school technology and home economics education textbooks were analyzed with respect to the three pre-parent education goals of developing perceptions and attitudes toward parenthood, learning parenting knowledge and skills, and reinforcing parental capacity. The results were as follows. First, textbook contents and activities reflected the three goals of pre-parent education in a balanced manner. Second, both the contents and activities of textbooks tried to motivate students to perceive parenthood and parenting through reflection on their relationship with their own parents. Third, because the textbooks encouraged students to consider parenthood and parenting, they acknowledged the importance of undertaking pre-parent education to reinforce their parental capacities. Using such textbooks in regular technology and home economics classes is expected to provide students with an opportunity to consider parenthood and shape their perceptions and attitudes accordingly, thereby allowing adolescents to prepare themselves for parenthood and become good parents.

The protoplasts of Saccharomyces cerevisiae D-71, a thermophilic strain and Zygosaccharomyces rouxii SR-S, an osmotolerant strain were fused, and a fusant (FS-RN 1) was selected, then was characterized for its genetic stability, DNA content, cell capacity, growth rate, tolerance to salts and chemicals, $\beta$-fructofuranosidase level and ethanol fermenting activity. After 6 months of preservation, 5.8% of the fusant clones were segregated to parental types. The DNA content and cell capacity of the fusant were greater than those of the parental strains. Lag period of growth for the fusant was longer than those for the parents. The fusant colonies showed pink-color reaction to triphenyltetrazolium chloride(TTC) test. The fusant appeared to have resistances to NaCl at moderate levels between both parental strains, and resistances to KCI, sodium propionate and cycloheximide similar to either one of the parents. $\beta$-Fructofuranosidase activity of the fusant was 24.2$\times$10$^{-3}$/IU/g(dry wt) for 3 days culture. Ethanol yields ofter 4 days of fermentation by the fusant at 3$0^{\circ}C$ were : 6.0%(v/v) from 40% of glucose and 8.8%(v/v) from 20% of sucrose.

Experiments were carried out to evaluate the standard gravity in determining potential kernel size and to determine the effective sampling way by analyzing intra - and inter - plant variations for some source and sink characters using eleven semi-dwarf indica and three japonica cultivars including four semi-dwarf indica nearisogenic lines. Also, additional experiments were conducted to understand yearly variation and variety x year interaction effects for ten characters related to source and sink and to characterize the varietal difference of pre- and post-heading self-competition employing three parental varieties and their F$\sub$5/ progenies in 1982 and 1983. It is desirable to determine the potential kernel size by average kernel wight of rice grains showing above 1.15 specific gravity. There was significant difference in leaf area per tiller, spikelets and sink capacity per panicle among vigorous, intermediate and inferior tillers classified by differentiated order and vigorousness. Although it was difficult to find out any significant difference in grain-fill ratio, ratio of perfectly ripened grain, potential kernel size and sink/source ratio between vigorous and intermediate tillers, there was big difference between them and inferior one. The coefficients of variation within each tiller-group for some characters related to source and sink were larger with the order of vigorous tillers < intermediate one '||'&'||'lt; inferior one, and the average heritability of all characters, evaluated by the ratio of varietal variance (equation omitted) to total variance (equation omitted), were higher with the order of inferior tillers '||'&'||'lt; intemediate one '||'&'||'lt; superior one. Therefore, it is desirable to sample the vigorous tillers to represent the varietal difference of these traits. '82-'83 year variations of three parental cultivars were significant for all traits except for leaf area/tiller, panicles/hill, leaf area index and rough rice yield. The characters showing highly significant variance of variety x year interaction were growth duration from transplanting to heading, leaf area/tiller, sink/source ratio, sink capacity/panicle and grain yield. Generalized yearly response of three parental varieties (Suweon 264, Raegyeong, IR1317-70-l) and their F$\sub$5/ progenies on the 1st and 2nd principal components extracted from ten source and sink characters generally exhibited reduction in both source and sink. However, there were diverse variety x year interactions such as progenies showing similar reaction with their parents and intermediate or recombinational yearly response with little or considerable yearly movement on the four-dimensional planes of the two upper principal components between 1982 and 1983. Sink characters revealing highly significant border effect were grain-fill ratio, spikelets and sink capacity per panicle. Among them the latter two especially showed significant variety x border effect interaction. Self-competition characterized by relative weakness of inside plant's sink characters compared to the border one was more severe during the reproductive stage before heading than maturing stage. Though the larger sink capacity per panicle generally disclosed the severer self-competition, some lines (like Suweon 264) revealed severe self-competition with small sink capacity while a few others showed tender self-competition in spite of big sink capacity per panicle.

The purpose of this study is to try to structuralize the perception of the mothers of science-gifted elementary students using the concept mapping approach. The mothers who participated in this research had children who were 5th and 6th graders selected as science-gifted by a regional education office, a science high school and two national universities in a city. One of the authors interviewed 26 mothers, and extracted 50 general statements of their perceptions about the career path of their children. Ten mothers who participated in interviews sorted a shuffled pack of statement cards. The categorization of the statements into the dissimilarity matrix was carried out by SPSS multidimensional scaling analysis and hierarchical cluster analysis to generate a conceptual diagram. After that 140 mothers rated each statement using a Likert-type response scale from one to five. The result showed six clusters of parental views such as were 'Burden of private education, grades and going to the next grade,' 'Thinking about career guidance in gifted education and school,' 'Parental roles in child career education,' 'Difficulties in career guidance at home,' 'Demand for strengthening the parental capacity for career guidance,' and 'Demand for social support.' 'Demand for social support' obtained the highest sympathy from mothers of elementary science gifted.

The purpose of this study is to explore the housing pathways of middle-class married women toward owning a first home. In doing so, an in-depth interview as a qualitative method was conducted, life history was utilized to track down the path to first-home owning, and all the interviews were transcribed for analysis. The research participants were well-educated middle-class full-time housewives owning a home. The findings indicated that family formation through marriage and child birth was a primary driving force to buy a home. It was shown that owning a home was perceived not just as a stepping stone for building both family wealth and social capital but as one of the most important pillars to reinforcing traditional family values. In spite of some intergenerational distinctions on the path toward home owning, commonalities across generations included that home owning was considered to be a social icon for middle-class, it became almost impossible for younger generations without parental support which stimulated the intergenerational transfer of wealth, and it was greatly determined by both family income (affordability) and home finance options(borrowing capacity). This research implies that the changing social landscape transforms the value on homeownership and could undermine the socioeconomic strengths of home owning. Nonetheless, it's of importance to strategically assist first homebuyers who are likely to be a member of middle-class.
