The direct impacts of individual materialism on price perceptions and price perceptions on patronage behavior have been limited in previous research. This study examined the impact of materialism on consumer perceptions of clothing price and the influence that price perceptions have on store patronage by consumers. Using factor analysis and stepwise regression analysis, results indicated that materialistic values revealed four factors (pursuit of happiness, acquisition centrality, success, and practical-consuming). Materialistic four values influence consumer attitudes toward the positive and negative roles of price. In turn, patronage is predicted by positive and negative price-perception. Implications and future research directions are also discussed.

Carbon nanofibers were formed on silicon substrate which was applied by negative direct current (DC) bias voltage using microwave plasma-enhanced chemical vapor deposition method. Formation of carbon nanofibers were varied according to the variation of the applied bias voltage. At -250 V, we found that the growth direction of carbon nanofibers followed the applied direction of the bias voltage. Based on these results, we suggest one of the possible techniques to control the growth direction of the carbon nanofibers.

This study uncovers the relationships between mental health, couple relationships and marital happiness. The sample included 180 inter-married Korean men. The data were analyzed by means of frequency, Pearson correlation and multiple regression analysis using the SPSS. Mental health is positively correlated with marital conflict, but is negatively correlated with efficient communication and marital happiness. Furthermore, marital conflict is negatively correlated with communication and marital happiness. Second, mental health has a positive influence on marital conflict and a negative influence on marital happiness. Depression and social mal-adaptation have a negative effect on communication and marital happiness. Marital conflict does not have a mediating effect on mental health and marital happiness. Third, depression and social mal-adaptation have a negative influence on communication and marital happiness. Communication has a mediating effect on mental health and marital happiness. In conclusion, to reduce marital conflict, it is important to intervene in inter-married Korean men's marital happiness through special education programs and counseling.

Hair style is an expression of beauty for individuals and at the same time a clear social representation. It may be regarded as a means of knowing social recognition about social values and groups of the moment. The hair style clearly discriminated so-called the new woman, emerged during Chosun's modernization, and the old woman. Thus the purpose of this study is to examine changes in social recognition about the behavioral style of the new woman by relating them with women' s movements and with changes in female education policies. Results of the study can be described as follows. First, the new women in the 1920s were evaluated positive as those who were leading struggles against Japan and enlightenment campaigns. But between the 1920s and the 1930s, those women were thought to be negative in that they were appearance-oriented, extravagant and sticking themselves to reality. Second, how a variety of social figures recognized short-hair was determined here through reviewing the mass media of the 1920s. At that time, some men were positive about short-hair like feminists while others denied the convenience of the hair style in life and were negative about the new women's individualism and pursuance of luxurious appearance. Third, there were both positive and negative social recognitions about short-hair in the 1930s. which were supported by the mass media of that time.

This study was conducted to develop a scale to evaluate maternal beliefs regarding employment and to demonstrate its validity. The subjects in the study included 225 mothers in Suncheon who had children under the age of 5. Initially, the definitions of beliefs associated with employment presented in previous studies were examined, after which the existing scale, Beliefs about the Consequence Maternal Employment for Young Children (BACMEC), was modified based the advice of three experts in child study. Next, 35 mothers who had preschool children were interviewed to assess their views on the positive and negative aspects of maternal employment. After excluding overlapping contents, a scale composed of 50 questions (24questions adapted from questions on the BACMEC and 26 created based on the results of the interview) was generated. Based on the result of factor and regression analysis, 27 (15questions regarding positive aspects of employment and 12 regarding negative aspects of employment) of the 50 questions were selected for use as the new scale. Reliability analysis showed satisfactory results (Cronbach's $\alpha$ = .89-.92). In conclusion, it is hoped that the scale for maternal beliefs in employment developed in this study will be used as a useful measurement tool in future studies conducted to evaluate maternal employment.

The purpose of this study was to investigate the middle-class housewives` experience of housing environment through their own cognitive expressions. Subjects were 18 housewives living in the apartments at Junggye-Dong, Seoul and Field survey method was used. Indepth interview technique with planned questionnaire was used. The contents of individual`s housing life history were recorded by means of a recording machine. Cognitive expressions of subjects ontheir experience of housing environment were analiyzed by Content Analysis. Subjects have respectively experienced various housing types. The housing experiences were classified by stimuli and respones. Stimuli were again classified by the factors and characteristics of housing environment, whereas responses were classified by types and directions. Negative experiences were more frequent than positive ones. Negative evaluations were appeared more frequently In such case as the existence of community facilities, interior structure, bathrooms, and heating systems. The positive emotional experiences appeared more frequently were the natural characteristic$ of outdoors. When all the contents were analyzed by housing types experienced, subjects negatively remembered community facilities in high-rise apartments, and positively outdoors in detached single houses including traditional houses, and negatively heating systems in low-rise apartments and tenement houses. These contents, especially positive and negative aspects of past experience. can be used as basic data to understand residents` reponses and to plan furture houses more desirable for them.

This study investigated the relationships between parental marital conflict, attachment to parents and peer relationships. The mediating role of attachment to parents was also explored in the relationship between parental marital conflict and peer relationships. Two hundred eighty four 8th graders participated in this study. The participants answered questionnaires regarding parental marital conflict, attachment to parents, qualify of their friendship, and attachment to peers. The main results of the study are as follows: First, adolescents who perceived a higher level of parental marital conflict reported less positive feelings and more negative feelings toward their friends. They also reported lower peer attachment, and tended to perceive their friendship functions negative. Second, adolescents who showed stronger attachment to their parents reported more positive feelings and less negative feelings toward their friends. They reported higher peer attachment, and perceived friendship functions positively. Third, adolescents who perceived a higher level of parental marital conflict showed weaker attachment to their parents. Finally, attachment to fathers and mothers mediated the association between parental marital conflict and peer relationships. In other words, parental marital conflict had an indirect effect on peer relationships. The results suggest that attachment to fathers and mothers that resulted from parental marital conflict played an important role in determining peer relationships among adolescents, rather than the existence of the parental marital conflict itself.
