The multiple home PC, and home computing environment has undergone a significant evolution. And Internet explosion needs an integrated networking infrastructure within the home. Home networking is a concept that applies to the networking and application technologies to increase the comfort and ensure sharing and management of home resources as well as the provision of new, enhanced services. This paper proposes a Unification Protocol Architecture for home network. This Unification Protocol Architecture expect to a reference model in home network and to a foundation of the IIA (Internet Information Appliance) industry.

In this paper, the generalized hydrodynamic force and response of a flexible body are calculated at different reference coordinate systems. We generalize the equation of motion for a flexible body by using the conservation of momentum (Mei et al., 2005). To obtain the equations in the generalized mode, two different reference coordinates are adopted. The first is the body-fixed coordinate system by a rigid body motion. The other is the inertial coordinate system which has been adopted for the analysis. Using the perturbation scheme in the weakly-nonlinear assumption, the equations of motion are expanded up to second-order quantities and several second-order forces are obtained. Numerical tests are conducted for the flexible barge model in head waves and the vertical bending is only considered in the hydroelastic responses. The results show that the linear response does not have the difference between the two formulations. On the other hand, second-order quantities have different values for which the rigid body motion is relatively large. However, the total summation of second-order quantities has not shown a large difference at each reference coordinate system.

The purpose of this study is to suggest an environment-friendly design method of ecological architecture complex, with the reference to foreign cases. The ecological architecture is very similar to the natural ecosystem, but there is increasing international scientific consensus that human activities are having a discernable effect on the global climate. The most important thing is keep going harmoniously between preservation and development relevant with nature. In the process of ecological approaching concept, we need a method that from "architecture in a nature" to "architecture as one section of the nature" would be extended further, also the purpose of this study aims to achieve these kinds of ecological architecture. As a result of, in this Age of industrial science, we are proposing useful materials and suggestion regarding the ecological architecture planning of Korean cities, by preestimating the characteristics of a city heading toward the Age of the new ecological environment.

The telematics positioning testbed is an infrastructure to test and verify positioning technology, the sub-component of telernatics system. The positioning testbed provides the environment of performance analysis for acquisition of static and dynamic positioning information using telematics vehicle. This testbed consists of onboard positioning system, positioning reference station and lab positioning server. The onboard positioning system equipped in telematics vehicle, consists of target positioning system, reference positioning system, and analysis tool. A equipment acquiring high precision positioning data obtained from GPS combined with IMU was set as a reference positioning system. Analysis tool compares observed positioning data with high precision positioning information from a reference positioning system, and processes positioning information. Positioning reference station is RTK system used for reducing atmosphere error, and it transmits corrected information to reference positioning system. Positioning server which is located at laboratory manages positioning database and provides monitoring data to integrated testbed operating system. It is expected that the testbed supports commercialization of telernatics technology and services, integrated testing among component technology and verification.

Purpose: The purpose of this study is to provide reference points for the improvement work of churches' convenience facilities for the elderly. To do this, the study generates survey results, showing that the perception to significance of churches' convenience facilities is different among survey constituents. Method: The survey method was utilized. The study population for survey includes the aged believer over 65 years old, pastors, and architecture and/or interior design experts. The questionnaire was devised while consulting existing regulations regarding convenience facilities in general. Results: It is found that the perception to significance of installation standards for convenience facilities is different among survey constituents. Specifically, while the older believer group is perceived that installation standards for the small group meeting room of 'other facility' is comparatively more important, the pastor group and the expert group perceive that the 'intermediate facility' and 'inner facility' are more important. Implications: Participants involved in an improvement project of churches' convenience facilities may have a different perception about their importance due mainly to the degree of usage and the difference of perspectives. This study, therefore, can be used as a reference point for prioritizing improvement works of churches' convenience facilities for the elderly.

'협업 네트워크'는 가상기업, 동태적 공급망, 전문가 가상 커뮤니티 등을 포함하는 새로운연구 분야로서 협업 네트워크 조직(CNO)의 생성과 운영에 초점을 둔 모델링 언어가 필요한상황이다. 본 논문은 모델 자체의 표현력과 정보시스템의 구현 용이성을 모두 높인, CNO 대 상의 아키텍처 모델링 언어(CAML)를 제안하기 위한 것이다. CAML은 모델 기반 아키텍처 (MDA)에 입각해서 메타 모델과 도메인 모델을 통합하고 자크만 프레임워크에 입각해서 데이터, 프로세스, 링크, 참여자, 사건, 목적 등의 여러 초점을 통합할 수 있게 한 것이다. 공급망 문제의 모델링과 모델 변경 영향 분석을 통해 CAML의 유효성을 검토하였다.

Purpose: The ward division is a representative part of the hospital, where a variety of user activities are performed. Users can be broadly categorized as patients and carers, visitors, and medical staff (doctors and nurses). The relationship between these two is a major issue with ward planning as the patient's place of life centers around the hospital room and the task of the clinical workforce centers around the nursing station (NS). Against this backdrop, the study divides the ward units of the General Hospital of China into patient areas, medical team areas, supply areas, and public domain, with the focus on the ward areas affecting most significantly in the hospital patients. Methods: The theoretical advance studies of the standard ward unit are identified by the associated guidelines, articles, and documentation. Results: This study is a summary analysis of relevant regulations, reference literature, and drawing data from the target hospital. Further work is expected to be undertaken, including further surveys and observational surveys, to produce more detailed results. Implications: It is expected that the research in this paper will provide an effective reference for the future research of China General Hospital Ward department, so as to promote and improve the work system of China General Hospital Ward department.

Amid the crisis of global climate change, interest in low carbon and energy-saving building has been increasingly growing. Korea is likely to be designated as one of the countries subject to CO2 reduction under the 'Post-2012 Climate System' The efforts to minimize the building energy has been made and in line with the increasing need of low carbon and eco-friendly building, a demand for building evaluation programs has been on the rise. However, the metro logical data which is necessary for such program has not been effectively provided and moreover, the source, calculation method and period remain uncertain. This study was intended to evaluate the regional typical metro logical data (ISO TRY) provided by Korean Solar Energy Society and compile the month of test reference years (TRY), and analyze the regional weather using dry-bulb temperature, wet-bulb temperature and solar irradiance which are regarded the representative metro logical data.
