  • Recently, many research groups have studied on the epoxy-based multifunctional electrolyte to develop the structural composite bearing high mechanical properties without sacrificing the ionic conductivity at the same time. The studies on the optimal content and material selection for structural electrolyte have been published, while its curing behavior has not much analyzed yet. In this study, epoxy-based structural electrolyte containing solid electrolyte was prepared by varying the curing temperature and time. In addition, the ionic conductivities and mechanical properties of specimens were measured. We also find out the optimal hardening condition where the epoxy domain enables to be hardened within the range of temperature at which the thermal decomposition of electrolyte does not occur. Finally, we propose the multifunctional structural electrolyte showing achievable electrical and mechanical properties (282 MPa and $9{\times}10^{-6}S/cm@25^{\circ}C$).

  • The purpose of this study was to investigate the relationship between five aspects of clothing behavior and needs for exhibition and autonomy among high schoolgirls. Five aspects of clothing behavior were studied: fashion interest, clothing exhibition, attitudes toward the abolition of the school uniform and control of school dress. A questionnaire of 20 items prepared by Kahng, Lee, and Creekmore was used to assess fashion interest and clothing exhibition. Assessment of attitudes toward the abolition of school uniform and control of school dress was made with questions devised for this study and included several modified items from Kim's questionnaire. Preferences for fashion style were determined by line drawings representing current fashion and outdated fashion. The questionnaires were administered to 341 second year senior high school girls from three types of schools. Statistical analysis was performed using the correlation coefficient, chi-square test, ANOVA, The results were: 1) The need for exhibition was positively related to clothing exhibition and fashion interest, that is, students who had a higher need for exhibition were more interested in clothing exhibition and fashion. 2) The need for autonomy was positively related to attitudes toward the abolition of school uniform and control of school dress that is, students who had a higher need for autonomy wanted the abolition of school uniform and less control of school dress. 3) Fashion interest was positively related to preference for fashion style, that is, students who a higher fashion interest prefered fashinable styles in the selection of new clothes. 4) Scores of clothing exhibition and attitudes toward loosening of control of school dress were significantly different among three types of school. The orders from highest to lowest are following: single-sex preparatory, coeducational preparatory, vocational high school.

  • The purpose of this study was to identify middle-school boys' purchase behavior according to their shoes shopping orientation. A self-administered questionnaire was used to collect from 314 subjects. Factor analysis, Chi-square test, and one-way ANOVA were done using SPSS PC (Ver. 18.0). Most middle-school boys selected shoes that were 255~270mm, possessed on to two pairs of school shoes, searched for information for about five days before purchase, had spent 50,000~150,000 won on one to two pairs of shoes during the previous six months, saw design, comfort, and brand as their selection criteria, chose their shoes by themselves, shoes specialty stores, had favorite brands, preferred athletic shoes made of achromatic canvas, and bought new shoes when their old ones wore out. Factors of shoe shopping orientation were fashion and brand, economy, conformity, and comfort, and students were grouped into an active shopping group, an underdeveloped shopping orientation group, and a value pursuit group. The active shopping group bought more shoes, spent more on shoes, selected their shoes themselves, patronized discount shoe stores or specialty stores, and preferred national brand shoes. The underdeveloped shopping orientation group accepted their friends' opinions when selecting shoes and bought cheaper shoes. The value pursuit group accepted their parents' opinions when selecting shoes, patronized internet shopping malls or traditional markets, and selected cheaper shoes. The shoe shopping orientation of middle-school boys was immature, but they showed strong consumption needs.

  • The purpose of this study is to investigate the consumers′ cognition and buying behavior on sports brand character. Since the character industries are booming, this study focused on the source and the expression method of sports brand characters that are already known to consumers. Subjects of this study were university students who were interested in sports brand characters, living in Seoul and Kyenggi-do. The questionnaire were developed based on the previous studies. Data were analysed by Frequency analysis, ANOVA, Duncan Test, and Spearman′s Rho. The results were as follows: 1. The most preferred source of sports brands character was "illustrated human figure"(i.e. a famous athlete like Michael Jordan). And the most favorite expression method of character was the combination of letter and symbol as the character of ASICS and NIKE. 2. The important design factors of sports brand character were the symbolism and aesthetics. The consumer recognized NIKE as the most well-designed character design. 3. Consumers′ preference of sports brand was found to be NIKE, REEBOK, ADIDAS, and FILA, in order. The reasons for preference were the design, the brand image, and the quality. On the other hand, the most frequently purchased brand was NIKE, FILA, and ADIDAS in order. Most of the purchase took place in the brand outlet store, and the consumers usually came with their friends for purchase of sports brand. The display of store was the consumers′ major source of information. 4. The preference group of sports brand character recognized more importantly color, design, brand, and especially fashionability than the non-preference group. And the most important criteria for brand selection were design, price, and comfort orderly. 5. Female consumers recognized more importantly color, design, brand, and others′ recommendations than male consumers. The aged consumers recognized importantly durability, comfort, and quality.

  • This research is based on the Consumption Values Theory proposed by Sheth(1991). The purpose of this research is finding the factors related to the process of hospital choice. The expectation of six hospital outpatients 600 was analyzed by six consumption values categories: functional value, social value, emotional value, rarity value, condition value, health related values. The main results of this research is as following; 1. In the result of factor analysis 22 consumption value factors which affect the hospital preference were extracted; kindness/clearness, service speed, comfort of space, technical competence in functional values, high income/active social life, low income/blue collar unmarried/man, middle aged/big family, woman/married, introvert in social values, high-class, comfort, reliability in emotional value, newness, classiness in rarity value, social relationship, close to residence, social reputation in conditional values, priority on health, health behavior, active sense of value on health in health related values. 2. The difference of consumption values among hospital types were analyzed. The critical factors in reference for corporate hospitals newly established were kindness/clearness, service speed, convenience, classiness, comfort, and newness. University hospitals were preferred by the factors of reliability, and social reputation. In general hospital, convenience and close to residence were critical factor. 3. In logistic regression, age, marital status, education level and income as socio-demographic variables were significantly related to general hospital choice. Also service speed and close to residence were positively and high income/active social life and high class value were negatively related to general hospital choice. On university hospital choice, age and marital status, education show posive relationship whereas income showing negative relationship. Kindness/clearness, service speed, comfort of space, unmarried/man, comfortable feeling, newness and close to residence showed negative relationship with university hospital selection whereas technical competence, reliability in emotional value, classiness in rarity value, social relationship in functional values showed positive relationship. Lastly kindness/clearness, comfort of space, high income/active social life, unmarried/man, high-class, comfort and newness were positively related to corporate hospitals newly established choice in contrast to negative relationship in reliability in emotional value and classiness. In summary, we found that hospital user also choose to hospital in base of various consumption value. Further studies to investigate the hospital consumer behavior will be needed.

  • The purpose of this study was to analyze the brand preference, the clothing pursuit benefits, and the purchasing behavior of Chinese women. A survey questionnaire was distributed to Chinese women in their 20s and 30s. The surveys period was from 9th January 9th to $21^{st}$ February 2016. The respondents were 343 Chinese women living in Henan. The collected data was analyzed by frequency analysis, factor analysis, t-test, one-way analysis of variance, and Duncan's multiple range of verification. The key results of this study are herein summarized. The brands examined, listed in order of preference, are Ochirly, Only, Zara, Uniqlo, La Chapelle, H&M, Peace bird, Vero Moda, JNBY, and The Basic House. The five most preferred brands were then selected and further analyzed. For purchasing, the design and price were considered to be important, while for product evaluation, importance was given to the style, price, quality, and color. Factors important in the clothing pursuit benefits were found to be price pursuit, trend pursuit, brand pursuit, individual pursuit, comfort pursuit, and quality pursuit. Also, clothing pursuit benefits depends on the average monthly income, monthly clothing purchasing cost, and the education level of the individual. Lastly, we observed that the sources and store selection made noticeable difference in clothing pursuit benefits.

  • The purpose of this study is to develop core competencies for gifted education by utilizing Delphi survey methods and to present behavioral element selection and scale questions based on the definition of competencies. First, the core competence for gifted education was selected through literature analysis, and the first Delphi survey was conducted to verify that the definition of each competency is suitable for the competency name. Subsequently, through a second Delphi survey, detailed questions were developed and verified by expressing the capabilities required to develop core competencies as behavior elements. Through two rounds of Delphi surveys, eight key competencies were finally selected: attitude and practice willingness, communication and collaboration, information processing and tool utilization, creative problem solving, convergence and application, higher-order inference, community spirit, and learning achievement orientation. This study is meaningful in that it selects core competencies and behavior elements for gifted education that are necessary to pursue goals that meet social needs and it presents tools to measure the degree of competency improvement for gifted education.

  • The purpose of this study is identifying the relationship among the business strategy, order receiving capability and leverage variables of a construction company using industry characteristic variables, in addition to the explanation variables used in the previous studies. The samples of this study were limited to the construction companies listed in Korean stock market. This study built multiple regression analysis models, which have been frequently used in traditional previous studies, in the explanation of company capital structure. Empirical analysis on Static Trade-off Theory and Pecking Order Theory was done by the built model. The study results suggested that the capital structure determination behavior of a construction company generally follows Static Trade-off Theory; however, profitability was found to follow Pecking Order Theory. The explanation variables used in the previous capital structure studies mostly produced significant results; however, the variables, which this study experimentally used, did not produce significant results. It is believed that it implies that additional studies are required in the selection of variables and study methodology. Consequently, a case that unconditionally supports a particular theory is scarce. It has been also found that a case can support both theories at the same time. Therefore, it is believed that development study methodology or introduction of new study methodology that can identify the dynamic characteristic of construction company capital structure formation is required.
