The aim of this study is to investigate the pattern of inbound and outbound tourism and their receipts and expenditures in Korea, and wishes to suggest a policy implication. The finding in this research indicates that inbound tourism is mainly influenced by a relative income, while the receipts are effected not only by a scale of tourism, relative price, relative income, but also by the exchange rate. Outbound tourism and the expenditures are tentatively determined by a set of information which is synthetically made up by an economic factors. To this end, it could be concluded that tourism policy should be elaborately established to take of the inbound tourism, and appropriately designed information networking system for tourism would be helpful to assist the outbound tourism.

VoiceXML is a standard dialog mark-up language for the neat generation voice applications. The current VoiceXML 1.0 specification is silent on who place outbound calls for push-based voice applications. The push-barred voice applications become very important in modern information systems such as CRM. In this paper, we design and implement an extended VoiceXML platform that supports both inbound and outbound voice information services. We also extend the VoiceXML DTD so as to be able to inbound/outbound fax based on Call Control Requirements of W3C.

With the rapid spread of social media, video-sharing social media like YouTube has emerged as a consumption and distribution channel for entertainment goods such as music videos and movie trailers. In tourism research, there has been a lot of research of how the visual media such as movies and soap operas induced tourism. However, no studies have attempted to examine the role of social media as a music consumption channel and its impact on tourism. Expanding a body of media-induced tourism, we analysed the impact of video-sharing social media on music-induced tourism with a case of Korean pop music and inbound tourism to Korea. Developing a Web-crawler, we collected YouTube users' comments data on 166 Korean pop music video clips which were released from 2009 to 2012 with over 1 million view counts. Controlling many of the determinants of tourism and analysing country-by-country impact of YouTube comments with the panel data, we found that engagement of Korean pop music video clips on YouTube is a significant predictor for the flow of inbound tourists to Korea.

Due to the wide spread of customers' frequent access of non face-to-face services, there have been many attempts to improve customer satisfaction using huge amounts of data accumulated throughnon face-to-face channels. Usually, a call center is regarded to be one of the most representative non-faced channels. Therefore, it is important that a call center has enough agents to offer high level customer satisfaction. However, managing too many agents would increase the operational costs of a call center by increasing labor costs. Therefore, predicting and calculating the appropriate size of human resources of a call center is one of the most critical success factors of call center management. For this reason, most call centers are currently establishing a department of WFM(Work Force Management) to estimate the appropriate number of agents and to direct much effort to predict the volume of inbound calls. In real world applications, inbound call prediction is usually performed based on the intuition and experience of a domain expert. In other words, a domain expert usually predicts the volume of calls by calculating the average call of some periods and adjusting the average according tohis/her subjective estimation. However, this kind of approach has radical limitations in that the result of prediction might be strongly affected by the expert's personal experience and competence. It is often the case that a domain expert may predict inbound calls quite differently from anotherif the two experts have mutually different opinions on selecting influential variables and priorities among the variables. Moreover, it is almost impossible to logically clarify the process of expert's subjective prediction. Currently, to overcome the limitations of subjective call prediction, most call centers are adopting a WFMS(Workforce Management System) package in which expert's best practices are systemized. With WFMS, a user can predict the volume of calls by calculating the average call of each day of the week, excluding some eventful days. However, WFMS costs too much capital during the early stage of system establishment. Moreover, it is hard to reflect new information ontothe system when some factors affecting the amount of calls have been changed. In this paper, we attempt to devise a new model for predicting inbound calls that is not only based on theoretical background but also easily applicable to real world applications. Our model was mainly developed by the interactive decision tree technique, one of the most popular techniques in data mining. Therefore, we expect that our model can predict inbound calls automatically based on historical data, and it can utilize expert's domain knowledge during the process of tree construction. To analyze the accuracy of our model, we performed intensive experiments on a real case of one of the largest car insurance companies in Korea. In the case study, the prediction accuracy of the devised two models and traditional WFMS are analyzed with respect to the various error rates allowable. The experiments reveal that our data mining-based two models outperform WFMS in terms of predicting the amount of accident calls and fault calls in most experimental situations examined.

This paper considers a shipment planning of products from manufacturers to a third-party warehouse for demands with production time windows where a demand must be replenished in its time window. The underling lot-sizing model also assumes cargo delivery cost in each inbound replenishment to the warehouse. For this model, an optimal O($nT^4$) is presented where n is the number of demands and T is the length of the planning horizon.

During the last a few decades, internationalisation of universities has emerged as an important issue not only in developed countries but in developing countries. South Korea as a fast catch-up country has experienced a remarkable change in its higher education system. This change is largely related to the South Korean government's higher education policy and to economic developmental stages. Against this backdrop, in order to assess the internationalisation of Korean higher education, we focus on international student mobility rather than other criteria such as infrastructure or programmes for international students and faculties. According to the recent statistics, the number of inbound foreign students involved in Korean higher education has increased significantly since 2005. Nevertheless, compared to other OECD and Asian countries, the number of outbound students in Korean higher education is high, whereas the number of inbound foreign students in higher education in Korea is very low. Against these observations, Korean government's recent policies and efforts of Korean universities to improve internationalization are discussed. Finally, some policy implications are put forward.

In this paper, we performed numerical analysis to improve the heat exchange efficiency of wasted heat recovery ventilator which has a delivery and a exhaustion fan. One of the most important design factors that affect the efficiency of heat exchange is uniform counter-flow between inbound and outbound air flows. We had simulated several types of porous plates which were installed at air intake area. With plate having 45 degrees of installation angle and 15 mm diameter holes which are uniformly arranged, we can generate a uniform air flows at the area of porous media where inbound and outbound air flows are cross over. In addition, we installed a duct to reduce vortex flows at the outlet and to discharge exhaust airs rapidly. By using the proposed numerical assessment, we expect the improvement of the heat exchange efficiency of ventilator.

This article aimed to investigate problems relating to medical tourism based on a review of medical tourism reports and statistics in the global healthcare industry. To be a leading nation in the global healthcare industry, the needs and culture of many peoples, including Muslims, should be considered. Qualified medical services by JCI certification, including nutrition services, will provide opportunities to participate in the international and Asia medical tourism markets. In this article, the definitions of medical tourism, medical service, Halal and Haram, nutrition service for inbound Muslim patients, and Halal food supply in Korea were examined for medical service improvement. Mutual assistance between the government and private enterprise, sharing of medical service information, and construction of a cooperative network system are needed and should be supported by the government.
