Structural studies of membrane proteins, importantly involving interpretation of genomics information, many signaling pathway and major drug target for drug discovery, are having difficulty in characterizing the function using conventional solution nmr spectroscopy and x-ray crystallography because phospholipid bilayers hindered fast tumbling and crystallization. Here, we studied the structure of the pf1 coat protein in oriented phospholipid bilayers by home-built solid-state NMR probe. Bacteriophage pf1 was purified from Paeudomonas Aeruginosa and coat protein of bacteriophage pf1 was isolated from DNA and other proteins.

A knowledge map is a diagramed network among knowledge which is related with each other in terms of the referential navigation. To formally as well as structurely represent various contextual use of knowledge, the ontology technology has been recommended to be applied. This research proposes a methodology to build the ontology-based knowledge map promoting referential navigation between knowledge. To prove the validity of the proposed concepts, an ontology-based knowledge map is designed as an example, which demonstrates whether the designed knowledge network in the knowledge map is underpinned by the referential navigation between knowledge.

The u-City construction plan being executed presently involves such problem that services are provided in a suppliers-oriented direction while there are not much discussions on what u-Services citizens should be provided with and what u-Services that city government the supplier shall provide. In order to implement citizen-friendly u-Services the type of u-Services that offer just the right services efficient and convenient for citizens, u-Services should be provided based on active researches on the citizens' use and utilization of u-Services rather than u-Services being provided in suppliers' perspective as so far. To that end, there need be recognition and well-organized methodology that u-Services should be provided through humane, social and scientific analysis of the citizens that are to be provided with u-Services. Thus, in this study, the process of u-Services being transmitted was re-interpreted as background theory to deduce and apply services appropriate for u-Residential Space, and service science for u-Services the scientific and overall approach to seek for service innovation was applied to the development of u-Service deduction method based on such background theory. The u-Service methodology developed based on service science is judged able to deduce and provide u-Services appropriate for the intended services through scientific analysis of citizen-friendly u-Services.

Recently, Wireless Sensor Networks (WSN) require energy performance and guaranteed delivery delay time, contrarily with previous MAC protocols that aim to high throughput mostly. In order to satisfy the new significant requirements, many MAC protocols of WSN employ and try to enhance the duty cycle mechanism which is energy efficient technique in MAC layer. This duty cycle mechanism is oriented by toggling the transceiver conditions composed of wakeup and sleep states. The synchronous MAC protocols perform the period synchronization process. Hence, these are energy efficient in periodic monitoring environment, but are inefficient in where an event is incurred rarely and infrequently. Otherwise, the performance of asynchronous MAC protocols are contrarily with synchronous protocols. In this paper, we design two models consisting Always-busy and Always-idle ti simplify the general network congestion conditions. Through these models, moreover, we analyze two types MAC protocols in terms of energy efficiency and delay performance by analytical results. Additionally, we also evaluate two MAC protocols with two gongestion models that we designed. By the analytical and simulated results, we provide the general and efficient decision method in which protocols are more appropriate in a certain WSN environment.

This study intends to examine extensively on the current situation where the full capacity of 3D CG is not being highlighted because of the lack of the information and the awareness and to look at how the virtual reality technology is being applied ranging from the design of the clothes to the marketing. A set of processes ranging from the development of the clothing design to the marketing will be performed on the web. Designers will design with 3D CG and make the patterns and will hand this over to the producer together with the virtual swatch. But there are important problems to work out. First, it is the problem of the virtual fitting room. Second, it is the absence of the 3D CG, which is easy and convenient for the clothing design. Third, it is to perfect the visual reconstruction. Fourth, it is the security of the distribution system. Fifth, it also calls for the strengthened internet network that can smooth the flow of the tremendous data. Consumer will be able to produce according to their needs and will become designer and producer at the same time, resulting in the achievement of the consumer-oriented marketing in real sense.

This article analyses the concept of medicine in the legal context. It is not easy to define the concept of medicine because medical practice has various dimensions and the situation in which the practice is performed has a broad variety. The duty of medical law is to build the boundary of protection in that the nature of medicine would not be distorted by the factors of social systems like industry or governmental authorities. Without understanding the various dimensions - especially the dimension of Humanities and Sociology - of the medicine it is not possible to draw the limit on the performance of medicine appropriately. Concerning the medical practice (especially in the context of the regulation of medical licence), the enacted law (Medical Act) defines the concept just for form's sake and it finally depends on the interpretation of the legal enforcement authorities. Moreover, between the judgments of the courts there exists no coherent principles for the regulation and the interpretation of the Medical Act depends often on the riskiness, the abstract concept, which finally leads the interpretation to depend on the subject of the practice. On the contrary, the development and scientific movement of the technology tends to tighten the range of the medical professionals of medical practice and the perspectives of the medicine. Medical act is actually oriented at the patient's understanding of him- or herself. The above-mentioned tendency of the interpretation and the legal policy could lead the medicine away from its nature.

기술의 발전은 사회에 많은 변화를 일으키고 있다. 또한 기술의 발전은 예술 영역에 있어서도 형식과 내용에 많은 변화와 영향을 주고 있다. 컴퓨터 아트, 인터액티브 아트, 뉴 미디어 아트라고 불리는 새로운 예술 장르들이 탄생하였으며 예술가들은 다양한 기술과 접목하여 새로운 작품을 만들어 내고 있다. 뉴 미디어 아트의 중요한 특징 중 하나는 상호작용성인데 이것은 예술작품, 예술가, 그리고 관람자의 수용방식에 결정적인 변화를 가져왔다. 즉 뉴미디어 아트서의 예술작품은 완성태가 아닌 과정(process)으로 주어지고, 예술가는 작업의 초안자 또는 작업의 맥락을 규정하는 자로 규정되며, 작품과 관람자간의 상호작용이 무엇보다 강조된다. 그러나 기존의 뉴 미디어 작품에서 일어나는 상호작용성은 미리 계산된 범위 안에서 일어나는 제약이 있기에 진정한 상호작용성이라고 보기 힘들다는 비판도 있다. 이런 상호작용성은 공학적 세계관에 갇힌 닫힌 시스템으로서의 상호작용성이라고 말하며 미적인 상호 작용성의 도구로서 열린 시스템으로서의 새로운 작품의 필요성을 제시한 예술가들이 있다. 본 논문은 이러한 예술가들의 발자취를 따라 더 본질적인 미학적 상호작용성에 대한 고민과 함께 그에 따른 새로운 상호작용적 예술인 행동지향적 예술로서 인공지능, 인공생명 아트에 대하여 살펴보고자 한다.

The purpose of present paper is to investigate a fracture characteristics of the finite-width single-edge-notch(SEN) carbon fiber/epoxy reinforced plastics(CFRP) plates by using an acoustic emission(AE). Uni-directionally oriented 10 plies CFRPs specimen which had different notch length were prepared for monotonic tensile test. Matrix cracking appeared over whole testing process and fiber breaking appeared later on mainly Load distribution factor of the matrix confirmed that increased according as increases of plate width ratio. The amplitude distribution of AE signal from a specimens is an aid to the determination of the different fracture mechanism such as matrix cracking, disbonding, interfacial delamination, fiber pull-out, fiber breaking, and etc. In the result of AE amplitude distribution analysis, matrix cracking, fiber disbonding or interfacial delamination, and fiber pull-out or fiber breaking signal correspond to <65dB, <75dB, and <90dB respectively, Also, changes of the slope of cumulative AE energy represented crazing phenomena or degradation of materials.
