This study presents a effect of Supply Chain Management performance and e-commerce level on Healthcare Supply Chain integration. This study make a survey of purchasing Officer on Healthcare Supply Chain of hospitals. Hypotheses test by structure equation model. The healthcare supply chain integration affects on performance like other industries, but e-commerce level doesn`t affect on supply chain performance. But there is a slight correlation between e-commerce level and external integration of supply chain. Supply chain integration is very important for strength of health care competitiveness. And the performance has not been shown highly because infrastructure of IT is not yet established, experiences are not enough. But as time goes by, it will affect on supply chain performance much like other industries.

Hwang, Seok Young is a masculine and modern author having an obvious purpose on the epic plot. His viewpoint always converges on 'A Strange Land' and limited to the realistic achievement showed in it. This study started with a question about this statement. Thus, I investigated his literature based on his early novels such as 'Ga Hwa', 'A Pagoda', and 'A Returned Man', all of which are relatively unknown to the public. 'Golden Hill', a central space in 'Ga Hwa', reveals the dual aspects of the materialization; temptation and fear. Furthermore, there are forces found to nullify the boundaries between the reality and the fantasy, the real and the false, and the inside and the outside, and which are transformed to the point of new possibility. 'A Pagoda' is a story set in the Vietnamese War and it indicates the relationship between powerful countries and small countries, friends and enemies, and colonies and ruling governments, showing the 'possible' space where these relationships avoids the theory of adherence and fixed form. In 'A Returned Man', the career of the hero who had been decorated for bravery was ironically revealed through fantasy mechanism. The torture scene experienced in the middle of a fantasy can be regarded as a connection to the negative in that it functioned as a starting point of disclosure and reflection against the main violence. Therefore, the similarity found among these works is the dual aspects of the space. The reality/the fantasy, the genuine/the false, the offender/the victim, and the present/the past are all making various interpretative spaces pertinent to inconsistent agreement, double standards, anti-form, and anti-adherence. These duplicated spaces seek for new relations, rejecting the theory of existing dichotomy dominant to the space.
(Fe79C11B8Si2)100-XCrX (X = 0-8) 조성 비정질 리본의 크롬 함량에 따른 비정질 형성능, 기계적 특성 평가

Iron based amorphous ribbons with the nominal compositions of (Fe79C11B8Si2)100-XCrX (X = 0,2,4,6,8 at%) have been developed as reinforcements that can be applied to the concrete materials. Mechanical properties and glass forming ability of the ribbons can be enhanced by the optimum amounts of Cr additions that can also improve corrosion properties of the ribbons. Vein patterns typical of the fractured surface morphology of amorphous alloys have been observed on the surfaces of ribbons after tensile tests. It is inferred from the EDS analysis results of vein patterns that carbon segregations occur within the narrow shear band regions.

Liposarcomas are one of the most common soft-tissue sarcomas in adults. They usually arise in the deep soft tissues, and patients present with large painless masses. Four major types of liposarcomas are generally recognized and have epidemiologic and prognostic differences: atypical lipomatous neoplasm/well-differentiated; myxoid/round-cell; dedifferentiated; pleomorphic variants. Myxoid liposarcoma is the second most common type of liposarcoma, representing 30∼40% of all liposarcomas in the extremities. We report a case of myxoid liposarcoma in a 78-year-old man who presented with an asymptomatic, firm, deep-seated mass in the lateral aspect of his left upper arm.

A virtual network technology can provide a network reflecting the requirements of various services. The virtual network can distribute resources of the physical network to each virtual slice. An efficient resource distribution technique is needed to reflect the requirements of various services. Existing bandwidth distribution techniques can only control downlink traffic without taking traffic conditions on the network into account. Downlink and uplink share the same resources in a wireless network. The existing bandwidth distribution techniques assumed that all stations generate saturated traffic. Therefore, the existing bandwidth distribution technique cannot make traffic isolation in a virtual wireless network. In this paper, we proposed a traffic-based bandwidth control techniques to solve these problems. We applied Software-Defined Networking(SDN) to the virtual wireless network, monitored the traffic at each station, and searched for stations that generated unsaturated traffic. We also controlled both uplink and downlink traffics dynamically based on monitoring information. Our system can be implemented with legasy 802.11 clients and SDN-enabled APs. After the actual test bed configuration, it was compared to existing techniques. As a result, the distribution performance of the proposed technique was improved by 14% in maximum.

사용자 컨텍스트에 의거하여 개인화된 서비스를 제공하는 것은 점점 중요한 이슈가 되고 있다. 따라서 많은 서비스들은 더 나은 서비스를 제공하기 위해 Context-awareness 기술을 적용하고 있다. MPEG과 W3C 등의 표준화 기구에서도 Context-awareness 서비스를 개선하기 위한 컨텍스트 표준화를 위해 노력하고 있다. 하지만 기존의 MPEG7, MPEG-21, MPEG-V, EmotionML와 같은 컨텍스트 기반 표준화들은 다양한 시스템과 서비스에 적용하기에는 적합하지 않다. 이를 극복하기 위해 MPEG-UD 표준은 사용자를 위한 추천시 관련한 컨텍스트 정보를 사용하여 추천 결과를 만들어내는 서비스들과의 상호 호환성을 고려한 컨텍스트 표준화를 목표로 한다. 본 논문에서는 MPEG-UD를 비롯한 컨텍스트 관련 표준화 연구를 소개 하고 MPEG-UD 표준을 기반으로 한 RD-Engine 구조와 사용자 인터페이스 제공 서비스 시스템을 제안한다. 제안하는 시스템은 MPEG-UD로 서술되는 사용자의 컨텍스트를 사용하며, 특정 조건에 맞는 단위 리소스를 수집하고 디바이스의 특성을 반영하여 실시간으로 적응적인 사용자 인터페이스를 생성한다. 자동적으로 적응적인 개인 컨텍스트에 따른 적응적 사용자 인터페이스를 생성하는 시스템은 복합적 서비스 제공시 사용자의 UX 만족도를 높일 수 있을 것이다. Providing personalized services customized to users` needs and preferences becomes highlighted as a key area of user-context computing. It is essential for context-aware technology to be developed more intelligent and meaningful services by being widely applied to a variety of sectors and domains. SDO (Standard Development Organization) such as MPEG and W3C has been actively developed to be standardized services and to improve context-awareness services. Yet current standards related to context-aware technology, such as MPEG-7, MPEG-21, MPEG-V, and emotionML, are not capable enough to support various systems and diverse services. Against this backdrop, the MPEG User Description, referred to also as MPEG-UD Standard, is to ensure interoperability among recommendation services, which take into account user`s context when generating recommendations to users. In this light, we introduce standards related to the user context and propose the structure for RD-Engine and the Remote Responsive User Interface(RRUI) system in reference to MPEG-UD. This system collects unit resources matching specific condition according to the user`s contexts described by MPEG-UD. In so doing, it improves adaptive user interface considering device features in real-time. By automatically generating adaptive user interfaces tailored to an individual`s contexts, the proposed system aims to achieve high-quality user experience for a complex service.

A new excitation method of switched reluctance motor drive is described in this paper. This excitation method produces reluctance torque by mutual action between two phases as well as conventional self reluctance torque due to two phase excitation at a time. In other words, the change of self inductance and mutual inductance are used to produce torque. This paper suggests the operational principle, the mechanism of torque product of switched reluctance motor with two phase excitation, The acoustic noise characteristics of two phase excitation method are described against that of conventional excitation method.<br/> <br/>
