서비스 지향 아키텍처는 느슨하게 연결되고 상호 호환 가능한 서비스들의 결합을 통해 어플리케이션을 구현하는 기술이다. 서비스는 적절한 입도를 갖는 구현된 비즈니스 함수로 정의할 수 있고, 잘 구성된 인터페이스를 통해 외부에 노출된다. 서비스 모델링 단계에서 서비스의 입도(granularity)가 너무 작아지면, 서비스의 재사용성, 유연성이 낮아진다. 이런 서비스 입도의 문제로 인해 도메인 분석 모델로부터 적절한 추상화 레벨을 갖는 서비스를 식별하고 정의하는 것은 매우 중요한 일이다. 본 논문에서는 도메인 분석 모델인 유스케이스 모델로부터 서비스를 식별하기 위한 절차를 제안한다. 유스케이스와 유스케이스 기술서(description)로부터 태스크 트리를 생성하고, 태스크 트리의 분할과 결합을 통해 유스케이스를 재구성한다. 이렇게 재구성된 유스케이스들로부터 서비스를 식별하고, 명세할 수 있다. 본 논문에서 제안하는 방법은 이미 널리 사용되는 UML 유스케이스 모델을 사용하므로 다양한 플랫폼과 도메인에서 서비스 모델링을 위한 개발 시간과 노력을 최소화 할 수 있을 것으로 기대된다.

The ongoing proliferation of new services, applications, and contents is leading the Internet to an architectural crisis owing to its inability to provide efficient solutions to new requirements. Clean-slate architectures for the future Internet offer a new approach to tackle current and future challenges. This proposal introduces a novel clean-slate architecture in which the TCP/IP protocol stack is decoupled in basic functionalities, that is, atomic services (ASs). A negotiation protocol, which enables context-aware service discovery for providing adapted communications, is also specified. Then, we present how ASs can be discovered and composed according to requesters' requirements. In addition, a media service provisioning use case shows the benefits of our framework. Finally, a proof-of-concept implementation of the framework is described and analyzed. This paper describes the first clean-slate architecture aligned with the work done within the ISO/IEC Future Network working group.

This study was performed to determine the quality characteristics of Jeungpyun with the addition of soy yogurt (0%,3%, 6%, 9%, 12%). The proximate composition analysis showed that moisture contents of Jeungpyun were 49.87${\sim}$51.60%, and crush protein, lipid and ash contents were 2.58%, 0.21${\sim}$0.33% and 0.58${\sim}$1.05%, respectively. The pH ofJeungpyun was higher as the additive increased. Volume and symmetry index were higher as the additive increased, but uniformity index was no significant difference. L value and a value were the lowest in control group and increased with soy yogurt addition, while b value was decreased as amount of soy yogurt. Hardness, cohesiveness, gumminess were the highest in 9% group, springiness was the lowest in 9% group. In surface structure of Jeungpyun observed by SEM, cell size was the smallest and the cell uniformity was most regular in 12% group. According to sensory evaluation, appearance, taste and overall acceptance were highest in Jeungpyun with 9% soy yogurt. Therefore, Jeungpyun containing 9% soy yogurt was most preferable.

The purpose of this study is identify the status of the ward of public hospital for integrated nursing care service. Integrated nursing care service has been expanding on a national scale from 2016 but most of public hospitals are currently unable to operate due to nursing shortage. In this study 8 wards of public hospital have been chosen and analyzed. The measure of space program and area distribution(patient area percentage, staff area percentage, circulation area percentage), nurses's walking distance(distance from ns to patient room, distance from ns to core) were calculated by depthmapX and autocad programs. The result of this study is as follows. Nurse's walking distance is more than 24m so the efficiency of nurse's patient care is reduced. The percentage of patient area in double-corridor is higher and the patient feels more comfortable but the Nurse's walking distance is longer and the accessibility is lowered. NS should be located in the center of the ward and close to the core but some wards are not composed of proper space-separation and flow of human trrafic is overlapped. This study may serve as basic research for the architectural plan for future integrated nursing care ward.
