Recently, the R&D paradigm has become oriented toward convergence technology and interdisciplinary research. In this study, to elucidate the characteristics of research groups that promote the performance of convergence research, we take into account the input characteristics, disciplinary characteristics and collaborative characteristics of research groups. For this study purpose, 5,217 SCI papers published from 104 centers in Advanced Research Center Projects are analyzed as research outputs. The research findings are that the disciplinary balance in the interdisciplinary characteristics and the number of partners in the collaborative characteristics are positively related to the convergence of R&D outputs. The research field of a group introduced as a control variable exerts a significant effect on the convergent R&D outputs. In conclusion, it is necessary to organize internally with the same number of each disciplinary researcher in a research group and to activate external collaboration with partners in order to produce more outputs of convergent research.

This paper deals with the characteristics of the various fields of convergence studies and the current status of convergence education in domestic universities, based on a case study of Hanbat National University. Each case of convergence education for domestic universities is categorized and analyzed based on the disciplines of the convergence studies. Based on this analysis, a direction for the convergence education policy of university is suggested. The first suggestion is that convergence education should be based on the voluntary recognition of the necessity and meanings of it for both students and educators. Second is that the content of convergence education should be created according to the characteristics of the universities and related industrial structures. Finally, institutional and financial support from the universities should be extended to the self-organized student study groups.

This study analyzes the characteristics of broadcasting law and telecommunication law and suggested the key legitimate of regulation where convergence law would go for in the convergence circumstances by drawing the common and differential characteristics of two laws. Moreover, in the value of inherent pursuit of broadcasting law and telecommunication law, this paper examined whether these values continued to be reflected in the convergence law, and indicated the direction how these values should adopt in the convergence law. The result of this study shows that strong entry regulation has applied to both broadcasting and telecommunications industry. Also, both industries have been required to be universal service to realize the value. Meanwhile, the pursuit of original value of broadcasting law and telecommunication law can be summarized as secure of access and diversity, respectively. In the convergence law, it is necessary to compensate and modify the meaning of access and diversity based on traditional regulation.

This study has been conducted to determine the fatigue symptoms(MFS) and its convergence association with occupational stress(KOSS) among small scale manufacturing male workers. The self-administered questionnaires were given to 428 workers employed in 14 work places under 50 members of manufacturing industries during the period from September 1st to 15th, 2015. As a results, the level of fatigue symptoms(MFS) was positively correlated with occupational stress(KOSS). Hierarchial multiple regression analysis revealed that the factors of influence with explanatory powers of 34.1% on fatigue symptoms(MFS) included sex, BMI, subject health status, smoking, regular exercise, drinking coffee, visiting out-patient department, sense of satisfaction in job life, and occupational stress(KOSS). Above results suggested that the level of occupational stress(KOSS) is so convergence influenced by variable factors as well as sociodemographic characteristics, health related characteristics and job-related characteristics, to a greater extent, by occupational stress(KOSS).

In this paper, we develop a explosion-proof LED lighting (Ex circuit) circuit of Explosion-proof LED Signal Lamp (Ex LSL) to utilize the core module of the explosion-proof Local Control System (Ex LCS) for offshore plant applications. And then analyzed its electrical, optical and thermal characteristics. Ex circuit was applied input voltage from AC/DC(12~254) V. In this experiments, stable light-on characteristics were confirmed by eyes for the every input voltages with min. 78,462 and max. $517,975cd/m^2$ of luminance. also Output current and output luminance was made proportional. Because the measured maximum surface temperature of Ex circuit was $54.23^{\circ}C$ at AC 48 V, Ex circuit was rated with T6 of temperature class. Finally, Ex circuit was shown stable light on characteristics under the $-50^{\circ}C$ and $60^{\circ}C$ during 12 hours of test period.

The purpose of study was to test the effects of job characteristics and job stress on job satisfaction in the ICT Convergence Venture Companies and the moderating role of social support between job characteristics and job satisfaction. For this study, the data were collected from 15 ICT Convergence Ventures in metropolitan area by using structured questionnaires. The sample of 301 employees was selected and analyzed by hierarchical regression technique. The results showed that job characteristics had a positive effect on job satisfaction and job stress had a negative effect. And also found out social support had the moderate roles between job stress and job satisfaction except coworker support with regard to role ambiguity, whereas it did not serve as a moderate role between job characteristics and job satisfaction. The research results are summarized, the implications for ICT convergence Ventures were discussed, and the directions for future research were suggested.

As the convergence among technologies is reorganizing industry sectors, it is quite important to evaluate the probability of technological convergence, and to analyze how the technologies in a certain industry sector affect the same or other industry sectors. As a result, the large number of studies have been focused on the industry convergence. However, most of them have dealt mainly with case studies or strategy and policies and few efforts have been made to study it using quantitative data. The investigation of industry convergence using quantitative data will help understand the characteristics of industry and forecast the future of the industry from an objective point of view. Therefore, this research proposes a methodology to evaluate the possibilities of industry convergence using patent data. In particular, we emphasize the possibilities of technology convergence and suggest a technology relationship matrix to evaluate the technology convergence, as an antecedent of industry convergence. The feasibility and utility of the suggested methodology was verified with a case study on the convergence of IT and BT. The research results are expected to provide a useful guideline for developing a measure of convergence.

This research aims to analyze the prep-hop fashion, which is an original look created through the convergence of the hip-hop and preppy look, and identify the design characteristics of the prep-hop fashion. The style mixes the fashion of what was traditionally a lower-class look with the upper class. The design characteristics are as follows: First, the prep-hop fashion expresses slim, casual and sophisticated look with items and silhouettes. The items are categorized into jackets, shirts and pants. The prep-hop jackets provides a casual look to its wearer unlike the jackets of preppy or conservative looks. Slim suits show different meanings and features depending on the changes in the time and culture despite the continued use of the items. Second, the colors of the prep-hop fashion include overall basic colors used in the preppy look and hip-hop fashion. The aesthetic values of the colors express pleasant color images different from the conservative and resistant images expressed in the preppy and hip-hop style before the convergence, respectively. Third, the materials and patterns are expressed in a unique way to fulfill the emotional needs that are considered vital to contemporary fashion. The materials in the prep-hop fashion extend the ranges of usage by using the materials with unexpectedness broken out of general range of usage. While the use of the patterns is one of the methods to demonstrate that the prep-hop fashion is created by the convergence between hip-hop fashion and preppy look, the meaning concludes pleasantness and casualness different from the past. Fourth, the prep-hop fashion is mainly composed of hip-hop fashion accessories, which express the authenticity of the hip-hop fashion to protect the non-mainstream characteristics. The design characteristics of the prep-hop fashion pursue the individuality of the contemporary fashion, which lacks originality due to commercialization. The development of the prep-hop fashion, as a new form that combined contrasting genres and trends, is expected to develop more publicly.
