The present study attempted to offer more insights into the foreign consumers' consumption decision structure of Korean restaurants located in foreign countries. A survey was designed based on the means-end chain theory, using the laddering interview technique. The qualitative data obtained from 10 Americans, 10 Japanese, and 10 Chinese were content analyzed and resulted in categories such as 'new experience', 'interest in Korea', 'recommendation', 'good food', 'easy to access', 'service', 'dining environment', and 'price' as perceived attributes of choice. The hierarchical value maps linking attributes, psychological consequences, and terminal values were presented. The most frequent consequences were 'experience new culture', 'be exposed to new experience', and 'learn more about Korea' which were related to 'happiness', 'pleasure', 'good relationship', 'desire fulfillment', and 'self-satisfaction' as personal values. Laddering interviews, which required laborious analysis, provided important information on the relationship between perceived attributes and the reasons for choosing Korean restaurants.

All the countries in RA II (Asia Region in WMO) welcome the establishment of a Web site dedicated to agricultural meteorology, because it is believed that the best way to improve and speed up the flow of information is the use of the Internet and the establishment of a Web site. In providing recommendation for the promotion and improvement of the AgroMeteorological service in RA II, a couple of key suggestions were proposed: (a) Exchanges of data and AgroMeteorological knowledge between member countries and between RAs, (b) Exchanges of experts between member countries as a necessary way to share the knowledge, and (c) Joint research between member countries to solve common problems in AgroMeteorological affairs. In order to meet the above requirements for RA II, an AgroMeteorological information network will be the most critical and dynamic aspect in sustainable agriculture in this region. In addition, the establishment of a Core AgroMeteorological station, recommended by CAgM of WMO, will require its own information sharing systems for communication among member countries. Inevitable use of information technologies (IT) such as information networks, databases, simulation models, GIS, and RS for regional impact assessment of environmental change on AgroEcosystem will be enforced. Thus, the regional Internet-based Agrometeorological information network has been in place since 1999, though all contributions to it have been volunteered by individuals, institutes, universities, etc.

On road networks, the clustering of moving objects is important for traffic monitoring and routes recommendation. The existing schemes find out density route by considering the number of vehicles in a road segment. Since they don’t consider the features of each road segment such as width, length, and directions in a road network, the results are not correct in some real road networks. To overcome such problems, we propose a clustering method for congested routes discovering from the trajectories of moving objects on road networks. The proposed scheme can be divided into three steps. First, it divides each road network into segments with different width, length, and directions. Second, the congested road segments are detected through analyzing the trajectories of moving objects on the road network. The saturation degree of each road segment and the average moving speed of vehicles in a road segment are computed to detect the congested road segments. Finally, we compute the final congested routes by using a clustering scheme. The experimental results showed that the proposed scheme can efficiently discover the congested routes in different directions of the roads.

In video content watching service, when a user requests video content, the content server has to transmit the entire video to the client for watching. This transmission delay increases as the size of video content increases. In order to solve the transmission delay problem, a prefetching technique can be used in which a video content to be watched by a user is predicted and transmitted to a client before the user requests it. In this paper, we propose a prefetching system considering multiple indices for video content. In the proposed method, video content to be prefetched is selected by comprehensively analyzing the order relation index indicating the order of viewing the videos of the users, the similarity index between the video contents, and the popularity index reflecting the viewing frequency of the video content. Experimental results show that the maximum accuracy is achieved when prefetching uses only the order relation index for movie contents.

Purpose: Majority of bridges and roads in Gangwon Province have been carrying loads associated with heavy materials such as rocks, mining products, and cement. This location-specific live loads have contributed to the present situation of overloading, compared to other provinces in Korea. However, the bridges in Gangwon province are designed by national bridge design specification, without considering the location-specific live load characteristics. Therefore, this study focuses on the real traffic data accumulated on regional weighing station to verify the live load characteristics, including actual live load gross vehicle weight, axle weight axle spacings, and number of trucks. Methods: In order to take into account the location specific live load, a governmental weigh station (38th national highway Miro) have been selected and the passing truck data are processed. Based on the truck survey, trucks are categorized into 3 different shapes, and each shape has been idealized into normal distribution. Then, the resulting survey data are processed to predict the target maximum live load values, including the axle loads and gross vehicle weights in 75 years service life span. Results: The results are compared to the nationally used DB-24 live loads, and the results show that nationally recognized DB-24 live load does not sufficiently represent real traffic in mountaineous region in Gangwon province. Conclusion: The comparison results in the recommendation of location-specific live load that should be taken into account for bridge design and evaluation.

Patient satisfaction is an important factor in evaluating the quality of care. Patient satisfaction may be used to evaluate provider services and facilities, and used to predict the patient returns to a facility. The patients decision whether the patient returns to a facility or whether the patient recommends the facility to other people may be affected by a variety of factors of patient satisfaction. This study is to develop and test of a translated and modified Goldstein's instrument that measures patient satisfaction among physical therapists patients and clients. A self-administered questionnaire survey was conducted in Seoul, Chung-Joo and Bu-Cheon cities. Survey data was obtained from 743 patients who visited the physical therapy practice at university hospitals, general hospitals and clinics. The instrument developed by Goldstein was used and translated into Korean. Several items were added to the instrument. Patient's opinions of service in each domain measured using 5-point Likert-type scales that ranged from strongly disagree to strongly agree. Principal components analysis with varimax rotation was used to indicate which questions examined similar components of patient satisfaction. Component analysis indicated eight scales (kindness, scheduling, recommendation, convenience of parking, privacy, and waiting time). Different types of validity were established well. The coefficient of reliability (Cronbach alpha =.97) obtained for the instrument was clearly within a desired range.

Multinational Enterprises set the prices for transactions between affiliates based principally on their global interest. But the customs authority in Korea wants to set the arm's length price as high as possible to get higher dutiable value for customs purpose, while the internal tax authority in Korea prefers lower arm's length price to get higher value for corporation tax purpose by cutting costs. Problem caused by the inconsistent valuation methods on the same imported goods of the two tax authorities is the single most important tax issue facing multinational enterprises. In the meantime, the customs authority in Korea has thought that it is a universal trend worldwide for the Customs and Internal tax authorities to adopt different methods of valuation on transfer prices between related parties, so KCS couldn't accept APA prices. But the internal tax authority in Korea has taken the initiative in APA program so NTS provided taxpayer with safe-harbor. Recently, KCS created the Advance Customs Valuation Arrangement(ACVA) provisions in the 2008 revision bill of the Customs Act through benchmarking APAs program. Can APAs work for customs? Neither WCO or OECD presents any recommendation on the integration of the valuation methods, but calls for close cooperation between two authorities, which still leaves taxpayers very unstable. We will start to seek ways to integrate the customs valuation and transfer pricing in this study.
