  • The purpose of this study was to identify the effect of genderand body cathexis on clothing behavior (interest in clothing and clothing satisfaction/dissatisfaction). The questionnaire were administered to 395 college students living in Jechon. Data were analyzed by frequency, factor analysis, t-test, ANOVA, two-way ANOVA, Duncan's Multiple Range Test and Pearson's Correlation. The results of this study were as follows : 1) body-cathexis was higher in men than women. In general, students were more satisfied with upper body parts than lower body parts. 2) There was no relationship between interest in cloghing and body-cathexis. But woman showed more interest in clothing than man, therefore sex showed main effect. And there was interaction between sex and body-cathexis on interest in clothing. 3) Clothing satisfaction was devided into aesthetic/economical/practical factors. Among three satisfaction factors, body cathexis has the main effect in economic factor, and there was no interaction. But in aesthetic factor, gender and body-cathexis showed interaction and body-cathexis showed main effect.

  • One of the recent issues in design of the spot-welded structure such as the automobile body is to develop an economical prediction method of the fatigue design criterion without additional fatigue test. In this paper, as one of basic investigation for developing such methods, fracture mechanical approach was investigated. First, the Model I, Mode II and Mode III, stress intensity factors were analyzed. Second, strain energy density factor (S) synthetically including them was calculated. And finally, in order to decide the systematic fatigue design criterion by using this strain energy density factor, fatigue data of the ΔP-N(sub)f obtained on the various in-plane bending type spot-welded lap joints were systematically re-arranged in the ΔS-N(sub)f relation. And its utility and reliability were verified by the theory of Weibull probability distribution function. The reliability of the proposed fatigue life prediction value at 10(sup)7 cycles by the strain energy density factor was estimated by 85%. Therefore, it is possible to decide the fatigue design criterion of spot-welded lap joint instead of the ΔP-N(sub)f relation.

  • This study examined the possible causes of nutritional inadequacy in Vietnamese immigrant women married to Korean husbands. Qualitative in-depth interviews were conducted with a sample of 34 Vietnamese marriage immigrant women and 17 Korean spouses participating in or having experienced Nutrition Plus from four Community Health Centers in Seoul, Korea. The study results showed that the nutritional staus of the Vietnamese marriage immigrant women was affected by the unfamiliar Korean food (cultural factor), low household income (economical factor), difficulty in purchasing Vietnamese food (environmental factor), and low accessibility to nutrition support systems (social factor). The Korean husbands' nutritional status was affected by the unfamiliar Vietnamese food (cultural factor), low household income (economic factor), and irregular working conditions (social factors). Nutritional interventions as a public service to the community needs to be developed and applied. Suggestions are presented regarding the future efforts to better understand and meet the nutrition needs of intermarried couples to respond to their heterogeneous needs and deliver adequate nutrition service to ever increasing intermarried families.

  • This study screened three natural ores (iron, mangenase, and zinc), two types of slags, and two elemental metals (elemental iron and zinc) to evaluate transformation characteristics of CAH mixtures [e.g. Carbontetrachloride (CT), 1,1,1-Trichloroethane (1,1,1-TCA), and Perchloroethene (PCE)]. To select an effective metal medium to treat the CAH mixtures, we measured transformation capacities (CAH mass ultimately transformed/mass of metal added) and the degree of dechlorination. We also considered economical efficiency of the metal media by comparing the value, CAH mass ultimately transformed divided by the price of metal medium added. A simplified mathematical model adapting CAH transformation capacity, first-order transformation kinetics, and available mass of metal transforming CAH was developed and used for estimating CAH transformation rate coefficient and longevity of the metal medium. CAH transformation capacity for elemental iron and elemental zinc were 4258~7129 and $4215{\sim}6330{\mu}g\;CAH\;transformed/g$ metal added, respectively, which are a factor of 80~200 higher than slags and natural ores. They also showed a factor of 1.1 to 2.2 greater degree of dechlorination than the others. Among natural ores and slags, Zinc ore showed the highest transformation capacity, $47{\sim}53{\mu}g\;CAH\;transformed/g$ metal added. Although zinc ore have smaller transformation capacity than elemental metals, economical efficiency of zinc ore is a factor of 10~20 greater than elemental metals tested. Consequently, zinc ore would be more economical medium than the others tested in this study. We estimated the pseudo first-order transformation rate of zinc ore was in the order of CT > 1,1,1-TCA > PCE.

  • The purpose of this study was to identify the relationship of clothing involvement and clothing buying behavior of women. A questionnaire was developed to measure clothing involvement, clothing purchasing motives, clothing purchasing criteria, fashion information sources, store selection criteria, and demographic characteristics. The questionnaire was administered to 430 female adults in Taegu. The data were analyzed using percentage, frequency, factor analysis, and t-test. The results of the study were s follows: 1. Subjects were divided into low clothing involved and high clothing involved groups. 2. Three dimensions of clothing purchasing motives were derived by factor analysis such as Aesthetic dependant, Impulsive, and Practical motive. Clothing purchasing criteria were factor analysed as Aesthetic, Qualitative, External, and Economical criterion. Fashion information sources were factor analysed as Printed & audio-visual oriented media, Marketer intensive search, Store search, Observation & Interpersonal search, and Experience. Store selection criteria were factor analyzed as Merchandise & Store atmosphere, Store convenience, and Brand & fashion. 3. There were significant differences between high involved and low involved consumers in clothing purchasing behavior. The high involved consumers showed more importance than low involved consumers about purchasing criteria expecially in aesthetic dependant. The high involved consumers put more importance to aesthetic, qualitative, and external criterion as clothing purchasing criteria. The high involved information sources. The high involved consumers were more concerned about merchandise & store atmosphere, and brand & fashion than low involved consumers in store selection criteria.
