In the 21st century, the dualistic worldview of the Cold War era collapsed and we entered an era of new creation and fusion. The fusion of different designs between East and West, the design activities of traditional clothing from the past, the use of new materials that are continuously being developed, and the mixing of unique items are being conducted in various fields. However, research is being conducted by combining fusion characteristics with hair. In addition, the period is short and the amount of research is small. Therefore, this study analyzed hairstyles of fusion images shown in hair collection using data of Juno Hair collection from 2013 to 2022 as analysis data and examined types of fusion images shown in the work of folk images, mixed images, and future images. Oriented images were divided into three categories and analyzed. In this study, we added Results of such research can be used not only as data for predicting future fashion trends, but also as basic data for exploring new design developments. In future research, it is expected that convergent research will be conducted, such as analyzing fusion images from an integrated perspective.

Translational research (TR) as high quality research can accelerate collaboration strongly between biotechnology-based researchers and clinical-research experts for overcoming diseases. TR facilitates basic science translated to clinical efficacy and effectiveness from bench (basic science) to bedside (clinical practice) for the enhancement of human health. Disease-oriented TR programs were defined as unilateral, bilateral and multilateral TR in this patent performance analysis. Patent performance was measured in a R&D project on Health and Medical Technology to enhance the productivity of R&D investment on disease-oriented TR in Health Technology (HT). Patent Map (PM) analysis and Bibliometrics were conducted to collect information for the assessment of research patents of TR programs. Futhermore, PIAS (Patent Information Analysis System) and Thinklear programs were applied for quantitative and qualitative analysis successfully. These indicate that multi-dimensional analysis of patent performance for disease-oriented TR could promote the connection of R&D-IP (Research and Development-Intellectural Property) and R&BD (Research and Business Development) supporting system significantly.

A mobile agent is an autonomous software agent capable of moving from one computer to another while performing its tasks. We view the agent as a discrete event system in the view of its computation and communication. This paper presents a methodology far modeling and simulation of such a mobile agent system as a discrete event system. The methodology is based on the Mobile Discrete Event System Specification (MDEVS) formalism and the associated simulation environment AgentSim which are previously developed by the authors. Within the methodology an atomic model represents dynamics of a mobile agent; a coupled model is modeled as mobile agent servers for representation of structural changes between atomic agents. Being based on the object-oriented environment the modeling methodology exploits inheritance of basic classes AtomicModel and CoupledModel provided by AgentSim.

If the atmospheric concentrations of greenhouse gases double, the annual temperature increase in mean surface temperature relative to 1990 will be about 2.0 to $2.5^{\circ}C$ and the annual precipitation increase about $15{\%}$ by 2100 in Korea. When the temperature rises $2^{\circ}C$, the annual temperature will be $13^{\circ}C,\;15^{\circ}C,\;and\;16^{\circ}C$ in Western Central, Yeongnam Basin, and Southern Coastal respectively. Consequently the crop period could be prolonged $10{\~}29$ days. In the case of gradual global warming, annual crops could be adapted to the changed environment by breeding, and the perennial crops should be shifted to ether area. If global warming happens suddenly over the threshold of atmospheric greenhouse gases concentration, then we shall have disturbance of ecosystem. When $2^{\circ}C$ higher than present, the optimum flowering date of rice plant delayed about 10 days, so it may not possible to adopt the fate with present japonica rices, therefore, the recommended characteristics of rice varieties are longer basic vegetative period, more late maturing and higher ripening temperature. Barley and wheat crops could be shifted to northern coastal areas and apple production areas should be shifted to those areas under $13.5^{\circ}C$ in annual mean temperature at global warming. Ideotypes of crops under climate changes should have such ecological characteristics that are indispensable to accomplish the sustainable agriculture under increased $CO_{2}$ and temperature condition as the diversification of genetic resources from yield-oriented to biomass-oriented characteristics with the higher potentials of $CO_{2}$ absorption and Primary production. In addition, a heat-tolerance, a pest resistance, an environmental adaptability and a production stability should be also incorporated collectively into our integrated agroecosystem.

The aim of this study is to determine microstructure, chemical composition and crystal structure of hydroxyapatite for mouth teeth using optical microscopy and electron microscopy as well as electron probe micro-analysis (EPMA). Enamel, a protective cover to the teeth, consisted of rods oriented in regular and had relatively higher crystallinity and Ca component. In contrast, dentin showed a sponge-like microstructure with circular holes which were passages of dentinal tubules, and had higher Mg component than the enamel region due to its higher organic content. Hydroxyapatite crystals appeared as large rods in enamel, but as small needles in dentin. Their electron diffraction patterns were different by their crystallinity as well as by the organic content of the matrix.

Purpose - This study empirically analyzed the effect of the customer orientation in Insurance Salespersons on the perceived referral risk and referral intention. In the empirical study, we try to provide suggestions for reducing the perceived referral risk of customer oriented selling activities and improving the referral intentions according to customers' tendencies. Research design, data, and methodology - Data collection was conducted through the convenience sampling method for customers who had insurance coverage for about two months from March to May 2015. A total of 700 copies were distributed and 670 copies (95.7% recovery) were collected. Finally, 661 copies were used for final analysis. With the IBM PASW 22.0 statistical program. The interaction effect for the hypothesis test was generated by multiplying the average centralized independent variable and the control variable, and the average centralization variable was used to minimize the multi-collinearity problem of the interaction effect between the independent variable and the control variables. Results - Hypothesis 1 was adopted because the effect of customer-oriented selling activities on perceived referral risk were significantly negative. The effect of customer orientation on perceived referral risk is affected by innovative tendency, risk-taking tendency, and interpersonal tendency Interaction effect was observed. Therefore, Hypothesis 2-2, Hypothesis 2-3, Hypothesis 2-4 were adopted. The effect of customer-oriented selling activities on referral intention was significantly positive, and Hypothesis 3 was adopted. The effect of customer orientation was influenced by the interaction effect of innovative tendency. Therefore, only Hypothesis 4-2 was adopted. Finally, the effect of perceived referral risk on referral intention was significantly negative and hypothesis 5 was adopted. Conclusions - This study suggests that it is important for the salespeople to grasp the customers' propensity in consideration of the perceived referral risk and referral intention according to the moderating effect of customer orientation. In this study, we showed that customer-oriented selling activities positively influence referral intention by inducing perceived referral risk in customers with stronger risk-taking tendencies. It is thought that it will be an important basic data in designing a customer's selling strategy or conducting selling activities.

This study takes note on the need for the consideration of the relationship between the service contents and service space which libraries provide, since at the moment the demands of library users, purpose of using it, etc. gradually become varied. In this study, type classification of public libraries was done focused on the relationship between service contents and service space, targeting Japanese public libraries. Through linking approach between service contents and service space, the analysis of Japanese public libraries' characteristics and type characteristics could be captured. This study has ultimately aimed to prepare for the basic data which will help Korean public libraries to make connection between service contents and service space in the future. The collected service contents and service space had been analyzed by multi-dimensional data analysis methods such as the "Quantification Theory Analysis Type III" and "Cluster Analysis". After characters of libraries were analyzed, the findings of this study show the views such as "the field of information provided, the method of information provision, and the object of service provision." And types of 44 libraries are classified into those which have 6 kinds of characteristics as follows : (1) group-oriented libraries which provide the jobs and employment information, (2) libraries which provide the jobs and employment information through the counselling space, (3) individual-oriented libraries which provide the information of education-related fields, (4) group-oriented libraries which provide the information of education-related fields, (5) libraries which provide information focusing on the counselling space, (6) individual-oriented libraries which focused on the service provision.

Throughout the century, based on the precedent set by Flexner in the United States, almost every subsequent report on the reform of medical education has pointed out the need for more prevention-oriented teaching in the curriculum. This has been particularly so in countries like Korea where the basic public health services have been so important for the improvement of health of the people. And, in fact, preventive medicine and public health have contributed a great deal to the prevention of communicable diseases and prolongation of life expectancy. Recently, however, along with the educational reform that emphasizing the interdisciplinary teaching, integration of basic science and clinical education, and centralization of responsibility for the medical education curriculum, concerns are being voiced by preventive medicine educators. These concerns are primarily centered around the fear that the implementation of interdisciplinary, centrally administered courses would result in a weakening of content and teaching expertise as well as a loss of departmental power and control. This paper foresees that preventive medicine and public health will be more important in Korea in the future and proposes that preventive medicine educators will have to step forward and turn the challenges of curricula restructuring into opportunities to expand the role of preventive medicine in the curricula of their institutions.
