Purpose - This research approaches to the new niche market of medical tourism to investigate how factors of cultural similarity influence the international distribution management. This study also estimates the interaction effects of distribution channel on the relationships of facility attributes and customers' destination choice behavior. Research design, data, and methodology - We collected the sample of 881 potential customers from the more economically developed regions in China. Regression analysis is used to confirm the relationships in the research model. Results - The result shows that cultural similarity plays an important moderating role in the relationships of facility attributes and destination choice intention. For instance, power distance and masculinity interact with the distribution facility characteristics of medical quality and reputation to influence customers' selection of the destination country. Individualism, powder distance, and masculinity play moderating roles when social environment affects destination choice intention. Especially, all the elements of cultural similarity moderate the relationships between travel cost and destination choice intention. This research also proves that depending on distribution channel, determinants of distribution facility are the critical predictors of intention to select the medical service outside of China. Conclusions - The study enables managers to develop the more effective strategies reflecting the interaction effects of cultural similarity and distribution channel on customers' decision-making process.

상수관망에서 다양한 제수밸브 분포간의 우열성 평가는 상수관망의 신뢰성 확보를 위해 필수적이다. 기존 상수관망에 새로운 제수밸브를 추가할 경우나 새로운 상수관망을 건설할 경우, 본 연구에서는 서로 다른 제수밸브 분포간의 우열성을 평가하여 좀 더 효율적인 제수밸브 분포를 선택할 수 있는 방법을 제안하고자 한다. 제안된 방법은 상수관 및 제수밸브의 파괴 모의를 바탕으로 하며 제수밸브 분포간의 우열성은 상수관망의 신뢰도를 기준으로 하였다. 상수관망의 신뢰도는 상수관 파괴당 평균적인 단수인구로 나타내지며 충분한 횟수의 상수관 및 제수밸브 파괴모의를 통해서 산정하였다. 제안된 방법의 적용성을 평가하기 위하여 실제 상수관망을 대상으로 새로운 제수밸브를 추가할 경우 두가지 다른 밸브분포를 결정한 후 우열성을 판별하였다. 또한 다양한 제수밸브 신뢰도에 따른 관파괴당 평균단수인구를 산정하여 제수밸브 신뢰도가 상수관망의 신뢰도 향상에 미치는 영향을 검증하였다.

The purpose of this paper is to take a closer look at an area having shorted emergence facilities and to determine optional candidate sites instead of vulnerable area by using GIS spatial analysis. Newly determined new candidate is performed by concerning spatial efficiency and spatial equity for a public service. It was determined through using the analyzing of the physical accessibility measure, the Location-Allocation, sort of classic model in spatial statistics and general network analysis. The area of this research has been used in administrative boundary of Young-Dong in Gangneung including 13 emergency, medical hospitals, 46 fire-stations and sub-fire stations. In general terms, what all this show is that the way we are approached for geographical view from using GIS spatial analyzing technique of determined location and allocation problem by the social, economical, political factor and simple administrative discrimination at the meantime. At the same time, with problem occurred in the space it is possible to make an Effective proposal or means, policy, decision for new candidate location-allocation suggesting optimum model.

Globalization of production, changing technology in ocean shipping sector, shifting bargaining power from port service provider to port users, changing distribution patterns of the containerization and new implementation for the environment and safety concerns introduced new ways of administration in port sector. In these days, port industries cannot survive alone. Port operation and management has to be proactive to cooperate and integrate with other port operators or other industries. In the 21st century, cooperation in maritime sector is more common than that in the past with several different reasons in a mixture of forms of cooperation. Cooperation among port authorities, port operators, shipping line, inland transport service providers and/or related organizations themselves becomes to exist to overcome the challenges and development of the global transport chain. This paper investigates the concept of port cooperation and the case analysis of the cooperation in the port industry.

Operational applications such as service restoration, voltage control and protection coordination are calculated based on the active and reactive power loading of the sections in the distribution networks. Loadings of the sections are estimated using the voltage and current measured from the automatic switches deployed along the primary feeders. But, due to the characteristics of the potential transformer attached to the switches, accuracy of the voltage magnitude is not acceptable to be used for section loading calculation. This paper proposes a new accurate section loading estimation method through voltage measurement error compensation by calculating voltage drop of the distribution line. In order to establish feasibility of the proposed method, various case studies based on Matlab simulation have been performed.

Pattern matching is increasingly being employed in various researches as health care service, RFID-based system, facility management, and surveillance. Geosensor filter correlates a data stream to match specific patterns in distribution environments. In this paper, we present a geosensor query language to represent efficiently declarative geosensor query. Geosensor operators are proposed to use for fast query processing in terms of spatial and temporal area in distribution environments. We also propose a geosensor filter to match new query predicates into incoming stream predicates. Our filter can reduce the volume of transmission data and save power consumption of sensors. It can be utilized the stream data mining system to process in real-time various data as location, time, and geosensor information in distribution environments.

The Natural Resource Conservation Service Curve Number(NRCS-CN) method is one of the widely used methods for computation of runoff from a basin. However, NRCS-CN method has weak point in that the spatial land use distribution characteristics are ignored by using area weighted CN value. This study developed a program which can estimate runoff by considering spatial distribution of CN and flow accumulation at the outlet of the watershed by appling Moglen's method. Comparisons between the results from NRCS-CN method and this study showed good agreement with measured data of experimental watersheds. The developed program predicted lower runoff than the conventional NRCS-CN method. As a conclusion, this study proposes a new design direction which can simulate real runoff phenomena. And the developed program could be applied into runoff minimization design for a basin development.

This paper introduces a clustering for Central Control System in New Distribution Automation System. There are three primary benefits to use clustering: improved availability, easier manageability and more cost-effective scalability. Availability: Clustering can automatically detect the failure of an application or server and quickly restart it on a surviving server. Clients only experience a momentary pause in service. Manageability: Clustering lets administrators quickly inspect the status of all cluster resources and easily move workload around onto different servers within a cluster. Scalability: Applications can use the Clustering services through the MSCS Application Programming Interface(API) to do dynamic load balancing and scale across multiple servers within a cluster.
