The purpose of this study is to compare tourism destination choices between Chinese and American international inbound tourists to Korea through social network analysis using 2013 International Visitor Survey data. The raw data were transcribed into social network data using UCINET and Pajek network software for social network analysis. The first part of network analysis dealt with destination choice network density and centralization from a global perspective. The result, showed a relatively low centralization value and high density value, which means that each tourism destination was almost linked to each other. The second part of network analysis dealt with destination choice network centrality and key player from node(tourism destination) perspective. The centrality value indicating that different tourism destinations of high centrality value were represented in Chinese and American tourism destination network. The key player destinations indicated that key tourism destinations in Chinese and American destination choice network were different, reflecting tourist``s destination choices by their unique culture. By understanding the several results, tourism destination marketers and industry practitioners can be supported in developing tourism destination marketing strategy and researchers can be supported in insight for future research direction. Also, this study will make significant contribution to our results understanding about the link between cultural distance and multi tourism destination choice.

본 연구에서는 가상가치평가법을 이용하여 중국관광객을 대상으로 한류 가치를 평가하였다. 이를 위해 CVM 시나리오를 작성하고, 이를 토대로 중국관광객을 대상으로 현장 설문조사(n=306)를 실시하였다. 또한, 한류가치를 평가하기 위해 로짓모델을 이용하였고, 지불의사금액 평균법과 절단된 평균법을 이용하였다. 중국관광객에 대한 1인당 한류의 가치를 절단된 평균법(WTP truncated mean)으로 추정한 결과, 대중문화의 경우 약 21만원, 한국문화의 경우 약 133만원으로 나타났다. 또한, 한류를 체험한 중국관광객 전체를 대상으로 한류가치를 추정한 결과, 연간 약 2조 2,400억원에 이르는 것으로 평가되었으며, 이중에서 대중문화 가치는 연간 약 3,000억원, 한국문화 가치는 약 1조 9,400억원으로 추정되었다. 따라서 한국문화의 한류가치가 대중문화의 한류가치보다 훨씬 높은 것으로 나타났다. 로짓모델 분석결과, 대중문화와 한국문화 모두 한류를 경험하고 한류에 대한 관심이 높은 사람일수록 한류체험에 대한 지불의사는 높은 것으로 나타났다. 또한, 대중문화의 경우 소득수준이 높을수록, 한국문화의 경우 연령과 교육수준이 높을수록 한류체험에 대한 지불의사가 높은 것으로 나타났다. 본 연구결과는 한류의 중요성에 대한 가치를 계량화했다는 점과 한류를 예측할 수 있는 주요 변수를 확인해냈다는데 측면에서 학술적, 실무적 가치가 있다고 판단된다. This study estimated the economic value of Hallyu for Chinese tourists using Contingent Valuation Method(CVM). An onsite survey was conducted for Chinese tourists based on CVM scenarios. Also, logit models with WTP(Willingness-To-Pay) mean and WTP truncated mean methods were used to estimate the economic value of Hallyu. The results of this study show that the economic value of Hallyu per capita Chinese tourist was estimated to be 206,972 Korean Won for Korean Pop culture and 1.33 million Won for Korean overall culture based on WTP truncated mean. Total annual economic value of Hallyu was estimated to be appropriately 2,240 billion Won of which value of Korean Pop culture was 300 billion Won and value of Korean overall Culture was 1,940 billion Won based on Chinese inbound tourists who experienced Hallyu. The findings of this study indicate that value of Korean overall culture was substantially greater than Korean Pop culture by more than six times. The results of logit model indicate that the higher Chinese tourists have education level the higher they were willingness to pay for Hallyu experience. Also, Chinese tourists who experienced Hallyu and were concerned with Hallyu were more willing to pay for Hallyu. The findings of this study provide academic and practical implications because this study quantified the importance of Hallyu and identified important variables of predicting Hallyu tourists.

A few years ago, The trains had little control equipment so the trains had little data transmission between control equipment. Recently, there is a lot of control equipment in a train as traction control, air conditioners and even internet access. for this reason, vehicle network must allow for the big amount of transmission data and must ensure the high reliability. In this paper we present monitering system for verify high reliability of data transmission of MVB of TCN which is an international standard of IEC 61375.

Despite of current research on motivation in the field of casino, little research has been conducted to identify motivations of inbound tourists to casinos and then segment them with distinct subgroups for practical marketing strategies. In this respect, this study aimed to identify the underlying dimensions of motivations for inbound casino visitors, using a factor analysis, segment the inbound casino market, using a clustering analysis based on derived motivation factors, and examine any differences between market segments with respect to socio-demographic and behavioral variables using cross-tabulation analysis. To this end, a survey was conducted to inbound tourists who played casino gambling at foreign visitors` casino in metropolitan Seoul. The factor analysis delineated five dimensions of casino motivations from 27 items of motives: Novelty, Challenge, Escape, Socialization, and Winning for Money. The results of cluster analysis indicate that two distinctive segments were identified: Moderate and Aggressive Casino Visitors. These two segments were significantly different with respect to nationality, educational level, marital status, age, purpose of visit, frequency of visit to Korea, companion, favorite games, and experience in international casino gambling. Based on the results of this study, marketing implications for casino managers were provided in the conclusion section.

사출 금형 설계에서 금형 온도 분포와 변형은 사출품의 플래시나 표면 단차에 주요한 영향 인자이다. 금형 온도 분포와 성형면의 압력분포를 예측하기 위하여 먼저 금형을 포함한 사출해석을 수행하였다. 계산된 온도분포와 압력분포는 금형 구조해석의 입력조건으로 사용하였다. 해석의 정확성을 위하여 금형 전체 세트에 대한 구조해석 조건을 도출하였다. 도출된 해석 모델로 성형면의 단차 및 벌어짐 크기에 대하여 금형 열팽창, 성형 중 온도변화의 영향을 분석하였다. 해석 결과를 바탕으로 성형면의 단차 감소 방안을 도출하였다. In the design of injection molds, the temperature distribution and deformation of the mold is one of the most important parameters that affect the flow characteristics, flash generation, and surface appearance, etc. Plastic injection analyses have been carried out to predict the temperature distribution of the mold and the pressure distribution on the cavity surface. As the input loads, we transfer the temperature and pressure results to the structural analysis. We compare the structural analysis results with the thermal expansion effect using the actual flash and step size of a smartphone cover part. To reduce the flash problem, we proposed a new mold design, and verified the results by performing simulations.
