In accidents involving the collision of railway vehicles, there is a risk that structural members might penetrate the cab frame of the railway vehicle in the space in which the driver or passengers are seated. To reduce this risk, worldwide, studies on the collision of railway vehicles are underway. In North America, the Code of Federal Regulations (CFR) was revised in 2010 to include crush criteria for a collision and the corner post in an end frame. In this study, a crush analysis and crush test for a collision post and a crash analysis for a rigid cylinder were performed according to the CFR. The analysis and test results were compared and reviewed. This study aims to determine the usefulness of crush analysis for developing various end frames, and to understand the crush and crash characteristics and review the accuracy of the analysis.

This paper presents a mechanical design of the deepwater pipeline wall thickness using the recent design rules. Characteristics and limitations of the new codes were identified through a case study design in the Gulf of Mexico. In addition to the ASME, API, and DVD codes, the code of federal regulations (CFR) was also utilized in the design. It was found that conservatism still exists within the collapse prediction for water depth greater than 1500 m. Comparision of the results from DNV and API codes were presented.

미연방통신위원회(FCC)에서는 무선전파를 사용하는 장비 및 부품들은 사용에 앞서 해당 기술기준에 적합한지를 인증받도록 하고 있다. FCC가 규정하고 있는 무선전파를 사용하고 있는 기기들에 대한 인증은 확인, 형식승인, 신고, 형식인정, 검증 등으로 분류된다. 본 고는 FCC의 전파응용기기 및 부품에 관한 인증제도를 조사 분석하여 향후 국내의 무선통신 기기들에 대한 인증제도의 확립 및 시험 방법 연구에 보탬이 되고자 한다.

The Code of Federal Regulations, Title 10, Part 50, Appendix H requires surveillance program for reactor pressure vessel(RPV) that the peak neutron fluence at the end of the design life of the vessel will exceed $1.0E+17n/cm^2$ (E>1.0MeV). 2D/1D Synthesis method based on DORT 3.1 transport calculation code has been widely used to determine fast neutron(E>1.0MeV) fluence exposure to RPV in the beltline region. RAPTOR-M3G(RApid Parallel Transport Of Radiation-Multiple 3D Geometries) performing full 3D transport calculation was developed by Westinghouse and KRIST(Korea Reactor Integrity Surveillance Technology) and applied for the evaluations of In-Vessel and Ex-Vessel neutron dosimetry. The reaction rates from measurement and calculation were compared and the results show good agreements each other.

In the environment of protectionism and bilateral trade agreements, Korea has promoted the conclusion of FTAs for its export-oriented trading policy, and 16 FTAs have entered into force at present. The main goal of this paper is to introduce the ISI system and its benefits and to extend the preferential rule of origin regime by using the Integrated Sourcing Initiative in the U.S. Code of Federal Regulations. The ISI illustrates with impressive clarity the fact that it considered as a tool of expanding the geographic limit of states and maximizing the global sourcing strategy of multinational corporations, allowing the developing countries to gain access to the market of developed ones that avoid the complexity and costs of many rules of origin regimes. This paper utilizes the literature research and analyzes a case study of FTAs which have adopted the ISI system. In conclusion, it presents several implications of additional measures to satisfy rules of origin in Korea's existing FTAs relating to the global supply chain strategy.

U.S contains the best technology, man power, and big investment in space. It considers space as not only a science and technology related area, but also as an industry and national security related area. Korea's space policy focuses on the development of space systems such as satellites and launch vehicles. Space policy systems of the two countries are also different, causing some discrepancy in mutual interest when we talk about cooperation with the U.S. This study introduced U.S space policy framework and compared it with Korea's policy. It is meaningful in that we can find an effective way of cooperation between two countries.

Nowadays, the growth rate of organisational politics in the library system is a cause of concern for library and information professionals. This has negatively impacted service delivery, most especially in public uni- versity libraries. This study examined the effect of organisational politics on job impetus among library personnel in selected public universities in South-west Nigeria. Three federal and three state universities were purposively selected such that one university was selected in each of the six states in South-west Nigeria. Total enumeration was used for all 187 library personnel in the six universities investigated. Using a descriptive survey of correlational type, a structured questionnaire was used to elicit information from respondents through survey monkey. Of 187 copies administered, 143, representing 76.5%, were retrieved and used for analysis. The results revealed a high level of organisational politics with low impetus. A strong inverse relationship was established between organisational politics and job impetus among library personnel in selected public universities in South-west Nigeria. Based on these, recommendations were made that Library personnel be encouraged to focus on their job specifications and limit organisational politics adhering to rules and regulations in the library and code of conduct for library staff.

Seismic design provisions in Korea has developed based on seismic provisions in United States (e.g., ATC 3-06). Current seismic design provisions in U .S. is moving toward adopting enhanced concept for design. Federal Emergence Management Agency (FEMA) Provides the NEHRP recommended Provisions for the Development of Seismic Regulations for New Buildings which can be used as a source document for use by any interested members of the building community. Current seismic design provisions in U .S. generally use a uni-level force. These provisions can not be satisfied if the limit state design is concerned. Limit state can be defined as a state causing undesirable performance o( a structure (e .g., serviceability, ultimate, buckling, etc.). Even if there are provision for controlling drift by two levels, it is still difficult to satisfy limit states using uni-level force. Architectural Institute of Japan (AIJ) uses a hi-level forces Int seismic loadings which can satisfy serviceability and ultimate limit state. However, the seismic parameters used in AIJ guideline are basically determined by subjective manner of code committee member and professions. These parameters need to be determined based on target quantities (target reliability, target energy dissipation, target displacement, target stress level, etc.). This study develops the method to determine the sesmic design parameters based on a certain taget level. Reliability is used as a target level and load factors in ANSI/ASCE 7-88 are selected as design parameters to be determined.
