The aim of this study is to examine the effect of transformational leadership of the leader in the wedding industry on the behavior of employees, and also to examine the equity perception of employees on their behavior. As a result of analysis, when the relation between transformational leadership and organizational citizenship behavior was examined, transformational leadership had not effect on behavior of employees. Thus, hypothesis 1 was rejected. As transformational leadership had significant effect on equity perception, hypothesis 2 was adopted. When the relation between equity perception and organizational citizenship behavior was analyzed, equity perception had significant effect on organizational citizenship behavior. Thus, hypothesis 3 was adopted. When the mediating effect of equity perception in the process of the effect of transformational leadership on organizational citizenship behavior as hypothesis 4 was examined, equity perception had partial mediating effects. Thus, hypothesis 4 was partially adopted. Accordingly, the leader in the wedding industry needs to demonstrate transformational leadership in order to promote organizational citizenship behavior of employees and also makes employees to feel impartial treatment and procedural impartiality. Further studies on practical measures of this issue are recommended.

The polymer insulators have been extensively used as an alternate material of ceramic insulators. However, when they are used in practical conditions, there are many problems of decreasing performance and shortening lifetime due to the exposures of degradation factors applied from the outdoor situations. Accordingly, the analysis of polymer degradations has been getting influential too late as one of important subjects for improvements of safety and reliability. Heat, water treatments are arbitrary simulated for finding out the initiations and processes of surface degradation on the polymer surface. Especially, this study is focused on the chemical changes properties. From the analysis of hydrophilic and hydrophobic molecular structures, final modeling of surface degradation is accomplished. We checked the contact angle depending on heat and moisturized accelerated degradation and ran an XPS analysis to check the mechanism change of the surface of the PCB polymer composite. The surface that had a tendency to attract moisture showed a decrease in the contact angle and generated a large amount of carboxyl($-COO^*$) radicals. The hydrophobized surface showed an increase in the contact angle and had a stable chemical composition constituted of the breakaway of oxygen radicals and the formation of double bond by carburization.

In order to research the factors influencing on the intentions for smart phone users to purchase "App-Book" in Korea, the study examines the levels of influences using on an additional variable, "cost", as well as the four key variables(performance expectancy, effort expectancy, social influence, and facilitating conditions) proposed by Unified Theory of Acceptance and Use of Technology(UTAUT; Venkatesh et al., 2003) validation. The result of the research confirms that the hypotheses of UTAUT model variable are generally supported by the information technology and many related previous researches. There is one exception, however, that facilitating conditions do not influence on the App-Book purchasing behavior by smart phone. It is revealed that the "age" and "experience" of the independent variables, as the proposed control variables, are most visible effect of control on the purchase intention and purchase behavior. This study has an academic significance of presenting a new integrated model to perform the research of the similar next App-Book services and purchase behavior related to the acceptance of new media. It also clarifies to the related companies that the usefulness of App-Book, the easiness of use, the cost and the social influence of purchasing App-Book by Outsider's intent. These aspects have practical implications as being presented.

It is necessary to find the practical considerations for applying RDA in building up the bibliographic records by importing RDA records from LC or OCLC in Korea. Especially, it is not easy to apply RDA appropriately because there are many alternatives and options in RDA. Therefore, this study is to grasp the way for applying RDA in building up the bibliographic records by reviewing LC RDA guidelines and analyzing RDA cataloging policies of libraries such as University of Chicago, North Carolina State University, and Standford University. As a result, these libraries have catalogued according to LC RDA guidelines and each library has its own guidelines, i.e., in statement of responsibilities, to transcribe all but exceptionally allow to transcribe only first, in publication statement, to use 264 field or 260 field, and in resource types, to transcribe all types of content, media and carrier or to transcribe 33X with GMD. Therefore followings would be considered for RDA application. First, some variations could be allowed for special situations of libraries in applying RDA and LC RDA guidelines. Second, the hybrid records that describe the core element of RDA to non-RDA records would be written in processing AACR2 to RDA. Third;the display of 33X field would be designed for expressing the resource types.

To improve management performance, medical institutions have great attentions to selecting the good employee. Through job placement, recruited employee performing a given task, previous studies have lack of research, how job environment affects the individual perception of job ability and individual performance. Therefore, targeting at the health care professional employees who work in the hospital, 134 questionnaire data collected, this study performed an empirical study on the relationship between person-job fit, self-efficacy and individual performance. Specifically, mediating effect of self-efficacy between person-job fit and individual performance was verified. The results indicate that first, person-job fit appeared to affect significantly to the sub-factor of self-efficacy (self-adjustment, confidence, goal-difficulty). Second, among the self-efficacy sub-factor, self-adjustment, confidence appeared to influence to the individual performance. Third, self-adjustment was fully mediated between person-job fit and individual performance and confidence was partially mediated between person-job fit and individual performance. These findings have the theoretical implications that self-efficacy studies are expanded to environmental factors and practical implications and study's limitations are discussed in terms of hospital organization's human resource management.

The number of use cases in machinery, aviation, and other industries that manufacture precise parts is increasing, and the construction industry is also increasingly using 3D printing technology. Although various materials for 3D printing are currently being developed and utilized, 3D printing manufacturing has a problem that the mechanical properties of the product may change when compared with conventional manufacturing methods such as injection and molding. This paper verifies the effect of the printing orientation on the mechanical properties of the product in the manufacture of PA12 material and providing basic data on the practical use of the materials as building subsidiary materials and structural materials. The results of the experiment showed that the product printed in the orientation of 0° showed the lowest overall strength and elongation rate, and the product printed in the orientation of 45° showed the highest figure. Overall, tensile strength and yield strength increased between 0° and 45°, and tended to decrease somewhat at 45° to 90°.

Social movements to improve the performance of buildings through remodeling of aging apartment houses are being captured. To this end, the remodeling construction cost analysis, structural analysis, and political institutional review have been conducted to suggest ways to activate the remodeling. However, although the method of analyzing construction cost for remodeling apartment houses is currently being proposed for research purposes, there are limitations in practical application possibilities. Specifically, In order to be used practically, it is applicable to cases that have already been completed or in progress, but cases that will occur in the future are also used for construction cost analysis, so the sustainability of the analysis method is lacking. For the purpose of this, we would like to suggest an automated estimating method. For the sustainability of construction cost estimates, Deep-Learning was introduced in the estimating procedure. Specifically, a method for automatically finding the relationship between design elements, work types, and cost increase factors that can occur in apartment remodeling was presented. In addition, Monte Carlo Simulation was included in the estimation procedure to compensate for the lack of uncertainty, which is the inherent limitation of the Deep Learning-based estimation. In order to present higher accuracy as cases are accumulated, a method of calculating higher accuracy by comparing the estimate result with the existing accumulated data was also suggested. In order to validate the sustainability of the automated estimates proposed in this study, 13 cases of learning procedures and an additional 2 cases of cumulative procedures were performed. As a result, a new construction cost estimating procedure was automatically presented that reflects the characteristics of the two additional projects. In this study, the method of estimate estimate was used using 15 cases, If the cases are accumulated and reflected, the effect of this study is expected to increase.
