This study presents work-family multiple-role planning by female university students as a new approach to worklife balance. Accordingly, this study examines university years as a key time frame during which students establish their career paths. This study integrates the social cognitive career theory and the planned behavior theory to design and evaluate a model that explains the work-family multiple-role planning process; in addition, it develops an optimal model to predict the intentions of female university students in work-family multiple-role planning. This study has conducted a structural survey with 500 female university students. After inspecting the data, the responses of 435 participants were used in the data analysis (SEM) with SPSS 21.0 and AMOS 21.0. The findings include the following. First, suitability of predictive model presents a satisfying fit. The major factors in this study's model (parental support, subjective norms, attitudes toward multiple-role planning, career decision self-efficacy, and outcome expectations) are verified as direct and indirect predictors of the work-family multiple-role planning intent of female university students. Second, the strongest predictive factor for the work-family multiple-role planning intent is the social environment factor (subjective norms), indicating that the influence of social pressure on intent is relatively large. The predictive model formulated under this study's integrated theoretical framework supplements existing research that focused on attitudes toward multiple-role planning as well as provides a more profound theoretical foundation on which work-family multiple-role planning behaviors can be better understood.

This study identifies consumers' perceived benefits and costs when using Samsung Health (a healthcare app) based on consumer reviews from Google Play Store's app and social media discourse. We examine the differences in the benefits and the costs of Samsung Health using these two sources of data. We conducted text frequency analysis, clustering analysis, and semantic network analysis using R programming. The major findings are as follows. First, consumers experience benefits and costs on several functions of the app, such as step counting, device interlocking, information acquisition, and competition with global consumers. Second, the results of semantic network analysis showed that there were eight benefit factors and three cost factors. We also found that the three costs correspond to the benefits, indicating that some consumers gained benefits from certain functions while others gained costs from the same functions. Third, the comparison between consumer app review and social media discourse showed that the former is appropriate to assess the performance of app functions, while the latter is appropriate to examine how the app is used in daily life and how consumers feel about it. The current study suggests managerial implications to healthcare app service providers regarding what they should strengthen and improve to enhance consumers' satisfaction. It also suggests some implications from the two media, which can be mutually complementary, for researchers who study consumer opinions.

In an attempt to investigate mothers' perceptions of factors affecting preschool children's food preferences, their policy improving food intake and belief in food selection, in-depth interviews with 30 mothers who had preschool children were conducted in Daegu and Busan. The interviews were tape-recorded and the contents of interviews were analysed by researchers. Most mothers and children liked meats. It was found that children usually disliked vegetables such as onions, carrots, and green onions. Mothers perceived that many factors affected their children's food preferences: mothers' and fathers' food preferences, food offering at meals. mothers' food intake during pregnancy, children's food intake during weaning period, heredity peer pressure, and advertisements on television. Mothers made efforts to improve childrens food intakes in many ways: change of cooking method, emphasizing function of nutrients and food for health, conciliation and enforcement, and comparison to other children. The most affecting belief for mothers in food selection was family members' food preference. Health, balance in nutrient intake degree of food processes food additives, chemicals, convenience, diversity, and economy were also important beliefs to select food. Convenience was especially the primary belief in choosing and preparing children's snacks. Mothers offered frozen dumplings and meat, instant noodles, tuna, and ham for snacks for convenience. These results showed that mothers understood many aspects affecting children's food preference tried to improve children s food intakes and had several beliefs in food selection. We concluded that it is necessary to give information for mothers to make healthy snacks in a short time and chance to learn cooking skills.

Objectives: The valid assessment of food and nutrients intakes using appropriate dietary intake method is necessary to improve the nutritional status of the hemodialysis (HD) patients. This study was conducted to compare the method between newly developed, semi-quantitative food frequency questionnaire (Semi-FFQ) and 7-day dietary records (7-DRs) for hemodialysis patients. Methods: We conducted both methods on 53 maintenance HD patients in two university hospitals. We calibrated the frequency, portion size and daily intake of 47 food items reported in Semi-FFQ. The food and nutrients intake was compared and the correlation of the two methods was analyzed. Also each nutrient intake was compared to recommended dietary allowance for Korean (KDRIs) and recommended nutrient reference value for HD patients. Results: Energy and energy-yielding nutrients intakes were significantly higher in the two methods (p<0.01). These support the possible reliability between Semi-FFQ and 7-DRs that is similar with regard to most mineral and vitamin intakes. Thus, the Semi-FFQ used in this study for the assessment of nutrient intakes of HD patients can be reliable for the assessment of the nutrient intake along with the 7-DRs. The correlation coefficients were higher for foods consumed daily, such as steamed rice, meat and chicken, bean, egg, milk, coffee and alcohol than for those of foods eaten rarely (p<0.01). Conclusions: The Semi-FFQ used in this study can be a reliable tool for the assessment of the HD patients' nutrient intake along with the 7-DRs, despite its limitations.

The purpose of this study was to analyze the factorial structure of the criteria on clothing selection. Data were obtained from 219 housewives in Seoul. 95 likert type questions were selected from the existing questionnaires and from the open end questions. The items were analyzed for discriminating power, followed by the factor analysis. 57 items were subjected to the principal component analysis with orthogonal rotation after extraction of 5 major factors. 47 items were found to be significantly loaded to at least one of the five factors. The factors had the following characteristics: Factor I. The persons scoring high on this factor would invest time and energy in their clothes to achieve their image and individuality. They were interested in clothes, appearance and fashion. Factor II. The persons scoring high on this factor were more concerned about the practicality of clothing, such as ease-of-care, comfort, texture and quality of fabric. They would not select the clothes which soiled easily and would not perform as expected. Factor III. High scores on this factor were associated with the eagerness to get the cloth-ing value for the money. They would make a long plan to buy an expensive clothing and choose a unique clothing regardless of fashion. Factor IV. A high score on this factor was suggestive of modesty. They were willing to buy inconspicuous clothes, such as dark or muted colors, small prints and conservative styles. Factor V. High scores on this factor were characterized by the desire for conformity and approval of their friends. This result may be used to develop an instrument to measure the criteria on clothing selection of consumer.

The studies on shrinkage and characteristics of the weft knitted fabrics were investigated under the various dry and wet treating conditions. Various relaxation values were found out according to treating conditions. The characteristics of knitted fabrics such as shrinkage rate, thickness, spirality, elongation and recovery were also measured. The used knitting yams were OE (open-end) cotton and POY (pre-oriented yarn)-DTY (draw textured yam) polyester. The conclusions obtained in this study are as follows. 1. In case of dry relaxation little change of Ks values was seen with increasing time after 48 hours. So it was found that relaxation shrinkage of dry relaxation reached its maximal state in about 48 hours. 2. In case of wet relaxation, higher Ks values were observed, in comparision with those of dry one and higher shrinkage rates were also observed. But when experimental temperature was constant, sudden marked increases in Ks values and shrinkage rates appeared through the initial 4 hours, and after that time little change was seen in them. 3. As Ks value increases, thickness also increased. But thickness showed to some degree stability around Ks value 23. 4. As Ks value increases, spirality values also increased gradually. But little change of spirality values was observed above a certain Ks values (cotton 22.5, polyester 21.5). 5. As Ks value increases, the elongation decreased under a certain load, and the recovery was random.

Baik-Eui is the white clothes and Korean typical way of wearing, Baik-Eui was used by the over 80$\~$90 percents of people, which proves that Baik-Eui was the very clothes of common people. Moreover, even King himself in Koryo Dynasty is said to have worn white clothes when he was out of official hours. And wearing Baik-Eui was regarded as polite manners among the noble men in Yi Dynasty in spite of strict prohibitions of wearing it. That fact proves that it was loved by Korean people in general. Baik-Eui can be found its origin from many peoples of North East Asia in ancient time. Some say that wearing Baik-Eui is considered as a kind of worship of the sun, or purity of Korean people. But from the economical point of view, Baik-Eui was primitive in it's color. It means that their clothes were made from original clothes, not dyed. This study on the social reasons affecting to Baik-Eui, they are summarized as follows; 1. This Baik-Eui had been originated from the ancient economical and rigid circumstances of society. Everlasting poverty and diprivation of joy in life of Korean naturally made them have inclination of wearing it 2. Also common people were restricted in their choice of dress color by government. Even rich could not wear a colored clothes except the dyes permitted by them. 3. Socially, People wore white clothes through various kinds of ceremony, among which funeral was the most important. As we had the large family system, and usually the funeral at that time was longer in its period than now. Thus, Korean got accustomed to wear whit clothes more and more.

This study aimed to investigate the competitive advantages of Chinese fashion industry and firms to Korean fashion industry by applying the generalized double-diamond theory. Data collection was done by internet and fax survey. Questionnaires were distributed to the Korean textiles and apparel firms who entered China for production anuor distribution. List of firms were provided by KOFOTI, KOTRA, and Korea Apparel Industry Association. Total 198 questionnaires were distributed, and 77 questionnaires were used for final analysis. The results were follows. Korea's competitiveness scores of double-diamond model were higher in every aspects, such as demand condition, infra/supportive industry, firms's strategy and competition except factor condition. Glottalization score in double diamond model measured by the degree of glottalization which was determined by international diamond factors which make firm's multinational/international activities possible. Chinese fashion industry's globalization score of factor condition was significantly higher than Korea, but for the rest of aspects, Korean fashion industry showed higher scores. Therefore, Korean fashion firms can overcome comparative disadvantage of factor condition by utilizing Chinese fashion industry no matter what type of entry. In addition, considering the growth rate of Chinese fashion industry and its power of influence in the world market, the entry to the global market of the Korean fashion industry can be possible.

The volatile concentrate obtained from the edible Korean dureup plant (Aralia elata Seem.) by a distillation-extraction system was separated into hydrocarbon and oxygen-containing fractions, and the latter was further separated into nine subfractions by silica gel column chromatography. Gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS) were utilized to identify 167 volatile compounds in the fractions. The volatile compounds included 72 hydrocarbons, 31 alcohols, 23 aldehydes, 16 esters, 10 acids, 6 ketons, 3 furans, 2 phenols, 1 indole, 1 oxide, 1 sulfide, and 1 lactone. ${\beta}-Caryopyllene$, a sesquiterpene hydrocarbon, was the most abundant volatile compound identified in Korean dureup (19.53%). Dureup oil was found to possess a woody or herbaceous aroma following sensory evaluation of each fraction and individual volatile component using a GC-sniff apparatus.
