  • In this study, a Self-learning Neural-Fuzzy Networks is presented, Because of the fuzzy controller property, the designing problems of fuzzy if-then rules, membership functions and inference methods are very complex task. Thus in this paper we proposed the Neural-Fuzzy Networks composed by Sugeno and Takagi's fuzzy inference method and learned by using temporal back propagation algorithm. The proposed method can refine automatically the fuzzy if-then rules without human expert's knowledges. The induction motor servo system is used to demonstrate the effectiveness of the proposed control scheme and the feasibility of the acquired fuzzy controller. All results are supported by simulation.

  • In this work, we fabricated various 2D metallic and polymeric nanopatterns with the feature resolution of sub-micrometer scale by using the method of microcontact printing ($\mu$ P) based on soft lithography. Silicon masters for the micromolding were made by e-beam lithography. Composite poly(dimethylsiloxane) (PDMS) molds were composed of a thin, hard layer supported by soft PDMS layer. Finally, monodisperse metal or polymer particles could be obtained in the prepared pattern for the application of electronic devices.

  • The purpose of this study was to develop the Resilience Scale for Children(RSC) and to evaluate its reliability and validity. The RSC was administered to 482 children in grades 4 through 6. Factor analysis of the 30 item scale demonstrated Cronbach's ${\alpha}=.89$ for internal consistency of total items. The results of the confirmatory factor analysis supported a five-factor structure. Retest stability was acceptable for the five-factors. Tests of the present scale for criterion-related validity compared favorably with Self-Perception Profile for Children (Lee, et al., 1992) and the Stress Coping Behavior Scale for Children (Kim and Kang, 2003) confirming its applicability to elementary school students for assessment of resilience.

  • Using a sample of employees in various hospitality organizations, we proposed that individual disposition such as tolerance for ambiguity, positve affectivity, internal locus of control, and self-efficacy, will influence hospitality employees' resitance to change. The results supported hypotheses. Ultimately, we hope the results of this study provide propoer guidelines with hospitality managers and employees to decrease thiere resistance to change such as new IS implementation and thus increase their willingness to adopt in implementing new IS.

  • This study examines changes in economy status of retailers with self-employed and introduce a re-education program for enhancing their market competition supported by KeiMyung University and the city of Daeku. There are more than 80 participants for this program, mostly employed in small business in such as supermarket, apparel industry, conventional type of market and so on. The questionnaires were administered to all participants and analyzed the level of satisfaction for categories included in survey to evaluate the program. The results of study leads us to suggest the ways how those small business families can survive in furture and give the motives to develop new marketing strategies.

  • The stage for Tadao Ando's architectural works is not only in Japan but extends to many countries around the world. His creations are not limited to the world of architecture, but are widely acclaimed supported by public people as well. Why Tadao Ando's works are acknowledged and acclaimed so extensively? Japanese traditional elements used in the his works makes it so. Tadao Ando argued intuition and insanity which were deprived by modernism could recover with locality and it's historic elements laid importance to the self. To realize that, it is necessary the regeneration of landscape which was based on the site and self-reflection must accomplished with the nature. So as to regeneration of landscape, he used Japanese Landscape-gardening and make the nature condensed. With the su-ki, he made the architectural elements simple. And with the Japanese detoured circulation, he made deep and various space. In that way, he intended the nature which is changed with his idea experienced the way of yu-gen.

  • The purpose of this study was to analyze a path model that investigated the relations among leisure participation, leisure satisfaction and life satisfaction of the elderly. For the purpose conceptual framework based on previous studies was suggested. The sample in this study consisted of 489 elderly living in Seoul. Daejeon Jeonju and daegu. Statistics employed for the analysis were frequencies means one way anova multiple regression and path analysis. The results showed some evidence that supported the conceptual framework. In path model elderly's health status total asset family relationship self-esteem locus of control leisure participation and leisure satisfaction had direct effects on the life satisfaction. Also total asset, self-esteem and leisure participation had indirect effects through leisure satisfaction.

  • Recent experimental evidence that fluorinated graphene creates local magnetic moments around F adatoms has not been supported by semilocal density-functional theory (DFT) calculations where the adsorption of an F adatom induces no magnetic moment in graphene. Here, we show that such an incorrect prediction of the nonmagnetic ground state is due to the self-interaction error inherent in semilocal exchange-correlation functionals. The present hybrid DFT calculation for an F adatom on graphene predicts not only a spin-polarized ground state with a spin moment of ${\sim}1{\mu}_B$, but also a long-range spin polarization caused by the bipartite nature of the graphene lattice as well as the induced spin polarization of the graphene states. The results provide support for the experimental observations of local magnetic moments in fluorinated graphene.

  • This study was a descriptive research study targeting medical students to determine the impact of self-directed learning ability, self-regulated learning, and communication ability on self-efficacy in performing medical treatment. This study randomly selected medical students from Region J, located in Province G, as the approximate population, and a total of 125 copies were finally analyzed. Descriptive statistics were analyzed using t-test, ANOVA, correlation, and multiple regression analysis using IBM SPSS/25. Self-efficacy in performing medical treatment was related to self-directed learning ability (r=.61, p<.001), self-regulated learning (r=.50, p<.001), and communication ability (r=.33, p<.001). There was a positive correlation with all of them. As a result of analyzing the variables that affect the subject's self-efficacy in performing medical treatment using hierarchical multiple regression, self-directed learning ability was found to be the factor that best predicts self-efficacy in performing medical treatment, followed by self-regulated learning and communication ability. The total explanatory power was 46.6%. Acquiring specialized knowledge and becoming a doctor after graduation through clinical practice and acquiring the basic clinical practice skills necessary to successfully perform one's duties are important tasks that medical students must accomplish. Therefore, in order to improve medical students' self-efficacy in performing medical treatment, the importance of improving health care, major satisfaction, and life satisfaction must be recognized and managed. In addition, efforts to develop programs and improve systematic systems that can improve self-directed learning, self-regulated learning, and communication skills should also be supported.

  • This study examined the role and relationship among cognitive response(attractiveness, familiarity, actual self-congruence, ideal self-congruence and sympathy) factors, emotional response(empathy, flow, affection) factors, identification mediating between cognitive and emotional response, and interactivity. Hypotheses based on literature reviews were analyzed and according to the results, all of hypotheses except two hypotheses were supported. Firstly, the results revealed that except characteristic attractiveness and actual self-congruence, story attractiveness, characteristic familiarity, story familiarity, and ideal self-congruence influenced on sympathy positively. Secondly, this study examined the role and relationship between identification mediating between cognitive and emotional response and interactivity. As a result, identification and interactivity mediated with sympathy and empathy had positive effects. Finally, in respect of emotional responses empathy, flow, and affection had positive effects.
