The purpose of the study was to investigate the mother-child interactions in terms of maternal child- rearing behavior, maternal self-esteem, and their school-age children's self-esteem. The subjects were, all living in the Seoul area. A pre-test was conducted twice on 98 subjects. Each time the values of Chronbach's ${\alpha}$ were obtained on maternal behavior, maternal self-esteem and children's self-esteem. Data analysis was by ANOVA, Pearson's product-moment correlation. multiple regression analysis. Chronbach's ${\alpha}$, and factor analysis. Children's self-esteem was positively related (1) to family background factors:educational level, employment status of mothers, social economic status, and number of siblings (2) to maternal self-esteem and (3) to maternal child-rearing behavior in the dimensions of affection, acceptance, and encouragement of independency. Children's self-esteem was negatively related to maternal child-rearing behavior in the dimensions of hostility, rejection and encouragement of dependency. The relative importance of independent variables on children's self-esteem was found to be in the following order:mother's educational level. social economic status, and number of siblings (${\beta}=0.5935$, p< .001), maternal child-rearing behavior in the affection-hostility dimension (${\beta}=0.0849$, p< .001), and in the acceptance-rejection dimension(${\beta}=0.0365$, p< .05). The regression model showed that 25 percent of the children's self-esteem could be accounted for by family background factors. and maternal child-rearing behavior in the affection-hostility dimension and the acceptance-rejection dimension ($R^2=0.25$).

Background: The gold standard diagnosis of H. pylori related gastritis is evidence of bacteria on histopathological examination of gastric mucosa. Our aim was to study the correlation between gastric mucosal morphology and histopathological severity of H. pylori related gastritis. Materials and Methods: Division was made on morphological features into:Type 1, showing regular arrangement of red dots; Type 2, showing cleft-like appearance; Type 3, with a mosaic appearance; and Type 4, having a mosaic appearance with focal or diffuse hyperemia. Results: Types 1 and 2 gastric mucosal morphologies were statistically significant in predicting an H. pylori negative status (137/145, p<0.01), while Types 3 and 4 were significant a positive status (139/155, p<0.01). The sensitivity, specificity, positive and negative predictive values of Type 3 and 4 morphologies for predicting H. pylori positive were 94.6%, 89.5%, 89.7% and 94.5%, respectively, with a good correlation with inflammation grading (p<0.01). Conclusions: Our study suggests that gastric mucosal morphology can be reliably identified using conventional white light source gastroscopy with good correlation between findings and inflammation grading.

The first purpose of this study was to reveal the types of shopping value of college students. The second purpose was to examine the change in the perception and management behaviors related to credit cards according to the types of shopping value. The third purpose was to examine the effects of shopping value on perception and management behaviors on credit cards. The data were collected from 392 college students in Seoul by a self-administered questionnaire. Analyses including frequency, mean, factor analysis, Cronbach's alpha, Pearson's correlation analysis, Crosstabulation analysis, analysis of variance, K-means Cluster analysis and Multiple linear regression were conducted using SPSS WIN12.0. The major findings were as follows. First, college students can be categorized into 3 types of shopping values by K-means Cluster analysis of 14 items. The groups were entitled the hedonistic shopping value, the utilitarian shopping value, and the saving shopping value. Second, positive perception and management behaviors related to credit cards were different depending on the types of shopping value. The hedonistic shopping value group had a higher level of positive perception of credit cards and a lower level of credit card management, compared with the other groups. The saving shopping value group had higher levels of both positive perception and management of credit cards. Among the three groups, the utilitarian shopping group had the lowest level of positive perception of credit cards, despite having ahigher level of credit card management. Lastly, the most effective variance on credit card management was the utilitarian shopping value. These results suggest that a healthy shopping value is very important for having a healthy perception and management of credit cards, because shopping value is a critical variance to affect perception and management of credit cards.

This study aims to evaluate psychometric properties of the korean version of the caregiver reaction assessment. A total of 253 family caregivers for older adults with physical or mental impairments are recruited using the purposive sampling method. The psychometric properties of the instrument are tested by item-analysis, exploratory factor analysis(EFA), and convergent and criterion-related validity. The results show that the internal consistency values for the five dimensions of the K-CRA are good. The convergent and criterion-related validity is empirically confirmed. The EFA with the principal component method reveals the factor structure in the observed variables. The findings of the study confirmed that the K-CRA was both reliable and valid. In conclusion, the K-CRA would be useful in clinical and research settings in South Korea.

To determine which are the culturally specific factors of Korean bereavement, this chapter focuses on the view of death and the traditional mourning process which reflect Korean values and norms. The formation of the Korean view and understanding of death has been strongly influenced by three of its major traditional religions: Shamanism, Buddhism, and Confucianism (Park:1994: Hao:1999) and Christianity more recently. Each religion has a different view of death and the appropriate expression of mourning. Korea accommodates funeral customs and rules strictly as a cultural system and has retained these traditions over a long period; hence, some of the traditional funeral rituals still remain in modern Korean life, although some of the rites have been simplified. We have looked at the various ways in which grief and mourning is displayed and shared in a collective manner over a long period of time. This fits in well within the other Eastern cultures that are collectively organized, and contrary to the Eurocentric models do not hastily seek to detach the living from the dead and recognize that grief is a long process, and different individuals may take different amounts of time to recover from the grief. The view of death and bereavement in Korea has sprung from the roots of three Korean religions, together with the recent addition of Christianity, although they mainly result from the three earlier religions. The beliefs of these religions are still closely linked together in the rituals of Korean bereavement on both conscious and unconscious levels. The influence of these religions is evident in practice through the bereaved family's mourning reactions, funeral rites and customs and its views about death. Korea used to have a period of mourning for three years, following traditional mourning rites; then the chief mourner and the bereaved families could return to their normal life. In spite of this long mourning process for the bereaved family, once the funeral ceremony is finished, people expect the bereaved family not to express their grief in public; even the bereaved family does not like to talk about death. The process for bereaved people is related to mourning processes in terms of detachment from the deceased in order to start a new life. Relatives and the community recommend the performance of the kut ceremony for relieving the grief of the bereaved. When one family member dies in an unlucky way, the bereaved family may have some fear or other psychological reactions of grief such as pain, depression, insomnia and nightmares, hallucinations or other physical reactions. Unlucky deaths give the bereaved a very painful time and these types of reactions are often more serious than reactions to natural death. But through the kut ceremony, the bereaved family can start to make a new relationship with the deceased. The taboo of this type of death and death generally remains a crucial aspect of the isolation that bereaved people might face and the collective nature of mourning(even where it is still present) is unable to address this aspect of the privatization of grief.

The recent global economic crisis has resulted in increased discussion and attention on the sharing economy, a form of economic activity where individuals share currently available products. This study investigates consumer sharing economy usage attitudes and usage intentions by applying rational choice theory. For this study, an investigation that had 400 adult consumers from across Korea answer a structured questionnaire was conducted. A statistical approach using SPSS ver. 22.0 was used to analyze the data. The study found that the consumer's sharing economy value and participation levels were higher than usual. Higher than usual consumption patterns were seen for the construct of rational behavior theory. An analysis of the relative influence of variables regarding sharing economy usage intention also found that usage intention was higher for those who had experienced using a sharing economy services rather than those who did not have experience. In addition, the sharing economy usage intention also increased along with the values for subjective norms, sharing economy usage attitudes, sharing economy participation, sharing economy emotional benefits, and increased values. This study found that fundamental materials for consumer education should be made to eliminate difficulties that consumers have when they use sharing economy services. It is also expected that economic policy will develop to stimulate the sharing economy in a stable manner, that sharing economy-related information will be provided to consumers, and that consumer policies will be prepared to prevent consumer problems before they occur.

The purpose of this study is to assess the sanitation level and purchase behavior of fishery products, and to identify management conditions of bad smell from cooking fish at home as perceived by housewives in a metropolitan area. Frequency analysis, descriptive analysis, and cross-tabulation analysis were employed as statistical techniques for current study. Total 270 were collected from housewives. The statistical variables included the kinds of cooking oil and the age of housewives, the types of hoods for fish roasting, the types of covers for fish grills, the number of family, the ventilation methods, and the maintenance of kitchen utensils based on family incomes, and they showed statistically significant differences(p<.05). Furthermore, the housewives whose sanitary cognition level for fishery products was high, the housewives whose level of purchase attitude was relatively high, and the housewives who utilized specialized kitchen utensils demonstrated statistically significant differences(p<.05). It resulted from the assessment of such actual conditions as difference of culinary environment according to the sanitation level of fishery products, the level of purchase attitude, and whether the housewives utilized special kitchen utensils or not. The more efforts were proved from those who had the intentions for improvement of an amenable culinary environment at homes, according to the higher income obtainers, the smaller nuclear family, the younger generation, whether the housewives utilized special kitchen utensils or not, and those who had the higher sanitary cognition level of fishery products. The above results were derived from an individual lifestyle or a dietary lifestyle, but eventually this seems to be related with the propensity and values hierarchy of individuals.

Family factors included in this study of the relation of family environment to the moral development of young children were: socioeconomic status, maternal values, mother's religion and the quality of the home environment. Forty-one 6- to 7-year-old children and their mothers were interviewed and observed in their home settings. Results indicated that the quality of the home environment was positively related to the moral development of children. Mothers who provided a more stimulating home environment had children who received higher scores on the Moral Development Scale. Regression analyses indicated that the quality of the home environment was the most significant predictor of the moral development of young children.

To elucidate the putative role of the amido group in the metal binding of the fuculose-1-phosphate aldolase from Methanococcus jannaschii, we have examined a potential targen using site-directed mutagenesis. The replacement of asparagine 25 with leucine or threonine was shown to have a negative effect, not only on catlytic efficiency, but also on substrage recognition as well. The Hill coefficient values yeilded a value of =1. All metals used with the wild-type aldolases exhibited higher activity than that of the mutants. The spectra of the mutants were quite different from the wild-type aldolase. A highly conserved amino acid of asparagine 25 in a related family of aldolase odes not appear to provide sufficient evidence for evolution.

Optimum preparation conditions for chicken head soup base were determined in terms of the effects of amount of chicken head and cooking time using response surface methodology based on sensory properties. Sensory properties that were evaluated were yellowness, turbidity, bloody, chicken-brothy, organ meat-like, and fat-like flavor. All values of sensory characteristics increased remarkably with an increase in the amount of chicken head and cooking time. The optimum amount of chicken head and cooking time were determined to be 1800 g and 150 minutes, respectively. Chicken head soup base had less fat, free amino acids, nucleotides, and its derivatives, but had significantly more cholesterol, sodium, and iron than whole chicken soup base. In flavor compound analysis, the amount of hexanal of the chicken head soup base, which is related to fat rancidity flavor, was 11-fold higher than that of the whole chicken soup base.
