C-ITS(Cooperative-Intelligent Transportation System) provides services that require strict real-time such as forward collision warning, road safety service and emergency stop. WAVE(Wireless Access in Vehicular Environments), a core technology of C-ITS, is a technology designed for high-speed driving. However, in order to provide stable communication service by applying to real road environment, various performance tests of real vehicular environment are required. In the real road environment, WAVE communication performance is influenced by the surrounding environment such as moving vehicle, road shape and topography. Especially, when the vehicle is moving at high speed, the traveling position according to the speed of the vehicle, The surrounding environment changes rapidly. Such changes are factors affecting the communication performance, therefore a system and methods for analyzing them are needed. In this paper, we propose the configuration and test method of an effective performance evaluation system under high-speed driving and describe the results of analyzing the communication performance based on the data measured through the actual vehicle test.

The purpose of this study was to verify the effects of emotional labor on casino dealers' burnout and depression. Burnout is a big problem which thwarts their professionalism and effectualness and the effectiveness of the service they provide. Depression is a core factor which affects one's mental health. To analyze the effects of emotional labor on casino workers' burnout and depression, we conducted a survey of 606 casino dealers of H resort and analyzed the results. Burnout was measured in terms of the client-related burnout and work-related burnout by the Copenhagen Burnout Inventory (CBI), and depression was measured by the Beck Depression Inventory (BDI). The research findings are as follows. First, the level of emotional labor (3.50) was higher than the mid-point on the 4 point Likert scale, and the work-related burnout (3.86) and client-related burnout (3.91) were higher than the mid-point on the 5 point Likert scale. Second, emotional labor was correlated to their depression and burnout. Third, emotional labor showed a significant difference according to gender, while burnout showed significant differences according to age, position and term of service. Fourth, emotional labor had an effect on the casino dealers' burnout and depression. We discussed the implications of these findings and possible strategies to alleviate this situation, for example, the passing of a law and development of an employee assistance program (EAP) to prevent their burnout and reduce their depression.

Financial technology (FinTech) is an emerging financial service sector include innovations in financial literacy and investment, retail banking, education, and crypto-currencies like bitcoin. One of the crucial branch of financial technology-third-party payment (TPP) is undergoing rapid growth, with online/mobile systems replacing offline financial systems. System quality and user attitudes are key perceptions driving third-party payment usage, the importance of these perceptions, however, may be different with countries as users' thinking varies from country to country. Thus, the purpose of this study is to elaborate how factors differ from China to Korea by drawing on the unified theory of acceptance and use of technology (UTAUT2). Additionally, this study also aims to propose a multi-attribute evaluation of the third-party online payment system based on analytic hierarchy process (AHP), fuzzy sets and technique for order performance by similarity to ideal solution (TOPSIS), to examine the relative importance of the perceptions influencing new technology adoption intention. The results showed that the price value has the most significant influence on Chinese perceptions, while the perceived credibility has the most significant effect on Korean perceptions. Sub-criteria also performs different results to Chinese and Korean third-party online payment system.

Previous studies related with the relationship between R&D and innovation have focused on the role of R&D on innovation, and the empirical results have been not consistent. Although government policy supports have been considered a crucial factor to make innovation, it is true that there are little studies investigating the moderating effects of government policy supports on the relationship between R&D and innovation. The studies related with government policy supports mainly examined the direct effects of government policy supports on innovation. Using 2008 innovation activity table from STEPI, this study investigated the effect of R&D on innovation and the moderating effects of government policy support on the relationship between R&D and innovation. The data used in this study contains 532 Korean small and medium sized firms and information was collected over 3 years(2006-2008). The empirical results reports that R&D positively influences innovation and the moderating effects of government policy on the relationship is statistically significant. Therefore, This study suggests that R&D is required to firms for innovation and government policy supports are needed for connecting the R&D and innovation.

This paper deals with the novel concept of neo-endogenous rural development which has been applied to explain the contemporary features of the European rural development. The notion of neo-endogenous rural development has been emerged in Europe because the pervious dichotomous concepts of exogenous and endogenous development are no longer useful for explaining the relationship between the local actors and the central or regional administrative organisations. The concept argues that the changing situation of rural regions at the initial stages of endogenous development could only be identified by the concept of neo-endogenous perspectives. Therefore, it tries to apply the concept for the Korean rural development policy which is called Regional Agricultural Cluster scheme. Explaining the development processes and the problems of the farmers group which carried out the project in a local level, this paper argues that the severe conflict between the farmers group and the City Office may be a typical incident of the neo-endogenous development. It expresses the power relations between the local groups and the political managing authority. With the case of the Prundle, it concludes that the neo-endogenous development is the essential stage for all the endogenous development to go through as an transitional one.

Recently, caching for the database-backed web applications has received much attention. The results of frequent queries could be cached for repeated reuse or for efficient processing of the relevant queries. Since the emergence of XML as a standard for data exchange on the web, today's web applications are to retrieve information from the remote XML sources across the network, and thus it is desirable to maintain the XML query results in the cache for the web applications. In this paper, we describe implementation of an XML query processing system that supports cache-answerability of XML queries, and evaluate its performance. XML path expression, which is one of the core features of XML query languages including XQuery, XPath, and XQL was considered as the XML query. Their result is maintained as an XML materialized view in the XML cache. The algorithms to rewrite the given XML path expression using its relevant materialized view proposed in [13] were implemented with RDBMS as XML store. The major issues of implementation are described in detail. The results of performance experiments conducted with the implemented system showed effectiveness of cache-answerability of XML queries. Comparison with previous research in terms of performance is also Provided.

산업단지는 지난 30년간 한국 산업의 성장을 이끌어 온 발전모형으로서 존재하여 왔으나, 최근 지식에 기초한 혁신창출형 경제체제가 국가 및 지역사회의 경쟁력을 위한 핵심요소로 부각되면서 '효율성' 측면에서 그 의미가 크게 퇴색되었다. 이를 위한 대안으로서 '클러스터'가 대두되어 다양한 분석연구가 수행되고 있으며, 정부와 지방자치단체들은 이를 바탕으로 각자의 특색에 맞는 클러스터 조성 정책을 펼치고 있다. 그러나, 기존의 연구들은 클러스터의 종류 및 발전단계에 관한 프레임워크 제시 등의 이론적 수준에 국한되어 있거나, 지역사례 연구를 통한 성공요인분석(CFS) 및 단순한 정책방향 제시 수준에 머물러 있는 한계를 보이고 있다. 본 연구는 '클러스터'에 관한 선행연구를 분석해 보고, 클러스터의 중요한 판단기준이 되는 군집도와 네트워크 연계 정도를 기준으로 한 '$2{\times}2$ 클러스터 전략격자모형'을 효과적인 클러스터 구축전략 수립을 위한 이론적 틀로서 제시하였다. 또한, 분석틀에 실질적인 사례로서 '충북지역의 SW산업'을 전략격자모형에 대응시켜 분석함으로써 전략격자의 유용성을 제시하였다. 이를 위해, 충북지역의 SW 공급업체와 수요업체를 대상으로 설문조사를 실시, 분석한 후 그 결과를 전략격자모형에 대응시켰다. 그 결과, 충북지역의 SW산업은 아직 산업단지 수준에 있는 것으로 분석되었고 충북의 SW산업의 충북 내의 수요만으로는 더 큰 성장이 어려운 것으로 분석, 지역 내에서의 수요창출을 목표로 하는 '단일 클러스터' 구축보다는 지역적 제약을 벗어난 '매가 클러스터'의 구축으로 지역 내외에서의 수요창출이 가능한 클러스터의 구축을 그 대안으로 제시하였다.${\alpha}$에 E. coli Jm109의 plasmid pBX19, pBR322를 전이시켰다. 6.

Sales representatives of automobile company play a key role in the circulation system. Given the characteristics of the good, consumers demand high-quality information and guides from the salespersons when they decide to purchase an automobile. Sales representatives provide service to the customers in accordance with their needs to help purchase decision-making process. Therefore, a sales representative's personal competence have a significant effect on sales performance. Based on this hypothesis, we assumed that personal competence of a salesperson has a positive correlation with sales performance. An empirical analysis was conducted to test the hypothesis. This study classifies personal competence into 4 independent variables((1) sales technique professionalism (2) salesperson's attitude and relationship with customers (3) emotion utilization (4) emotion control) and measures the correlation with the dependent variable(sales performance). To verify the relationship, we set and modified the hypothesis based on the precedent studies and researches. In addiction, a survey was conducted targeting 300 local salespersons from Gyeonggi-Gangwon region. 268 valid samples were used and analyzed with SPSS WIN24.0 statistical program. As a result of an empirical analysis, it turned out that sales technique professionalism and emotion utilization have positive correlation with sales performance. However, the result failed to support the assumption that sales representative's attitude and relationship with customers and emotion control have positive correlation with sales performance. At last the result revealed that personal competence should be considered as an important determinant of recruitment specification for sales representatives.

One of the key factors of a safe workplace is to communicate with the workers about safety. For this, natural gas workplace is developing and operating related programs or communication activities. But, if there are silence behavior of the workers on the safety issues in this process, no positive outcomes could be expected for the workplace. The purpose of this study is to examine how safety silence motives, silence behavior, and safety communication influence each other. A total of 233 questionnaires based on the workers of natural gas workplace (in Seoul and Gyeonggi) were analyzed. The confidence analysis is to check consistency of the questions, analysis of the correlations between factors, and regression analysis to verify the hypotheses. As a result, the safety silence motives affected safety communication more seriously than the silence behavior did. Safety communication influenced safety silence motives more significantly than the silence behavior. The safety silence motives can be one of the reasons for safety communication to fail, and it was confirmed that a good safety communication does not necessary mean that there is no safety silence motivation. Based on such results, it is expected that improving and developing the safety communication activities of the workplace, it would improve safety in workplace in general.
