The use of intravenous catheters are occasionally complicated by intravascular fragments and swelling of the catheter fragments. We present a patient in whom an intravenous catheter fragments was retrieved from the dorsal metacarpal vein following its incidental CT examination detection. The case of demonstrates the utility of microscopy and multi-detector CT in localizing small of subtle intravenous catheter fragments as a human error. A case of IV catheter fragments in the metacarpal vein, in which reproducible and microscopy data allowed complete localization of a missing fragments and guided surgery with respect to the optimal incision site for fragments removal. These reproducible studies may help to determine the best course of action and treatment for the patient who presents with such a case.

The spacer grid is one of the main structural components in the fuel assembly, which supports the fuel rods, guides cooling water, and protects the system from an external impact load, such as earthquakes. Therefore, the mechanical and structural properties of the spacer grids must be extensively examined while designing them. In this paper, a numerical method for predicting the buckling strength of spacer grids is presented. Numerical analyses on the buckling behavior of the spacer grids are performed for a various array of sizes of the grids considering that the spacer grid is an assembled structure with thin-walled plates and imposing proper boundary conditions by nonlinear dynamic finite element method using ABAQUS/Explicit. Buckling tests on several numbers of specimens of the spacer grid were also carried out in order to compare the results between the test and the simulation result. The drop test is accomplished by dropping a carriage on the specimen at a pre-determined position. From this test, the specimens are buckled only at the uppermost and the lowermost layer among the multi-cells, which is similar to the local buckling at the weakest point of the grid structure. The simulated results also similarly predicted the local buckling phenomena and were found to give good correspondence with the experimental values for the thin-walled grid structures.

In this paper, we introduce the estimation method by Risk or SIL(Safety Integrity Level) for the criterion of safety assurance and summarize each application method and target. IEC 62278(EN 50126) which is international standard for the specification and verification of the railway system RAMS indicate a criterion of safety assurance. Especially, it recommend the safety verification by continuous verification as the order of requirement establishment, design, manufacture, installation, operation, and maintenance for the equipment not easy to quantify the operation environment. In this paper, we study the SIL requirement allocation method relating to internal new system development and existing system improvement by analysing SIL recommendations which were used to understand SIL for a train control equipment in 1990s in IRSE and theoretically their allocation background. This paper help the safety management of Korea train control system to develope the quantitative management procedure as international level by analyzing the SIL requirement allocation by operation agency and the right SIL verification procedure by manufacture and indicating the example to assure safety because it is necessary for improvement and localization for the Korea train control system having highly dependence on aboard technology.

The purpose of this study is to analyze movie costume of main character and find design characteristic and historical spirit focusing on the movie, in which Ishioka Eiko, Japanese movie costume designer constructing unique design world, participated. The study captured images of three movies such as , and with Digital Multimedia Converting System and analyzed them by focusing on the pictures showing designer's intention and design characteristic well among acquired 319 pictures. The costumes addressing movie costume designer's sense of values are recreated as future-oriented new works and are expressed as creative costumes by acquiring inspiration from past factors, dissolving them and applying up-to-date technology. Movie costume shall reflect historical spirit of our age as movie shows social cultural trend including fashion trend of manufactured age. Ishioka Eiko has searched for the design, which is proper for three principles such as 'be unique', 'be eternal' and 'be innovative' and from the result of analyzing movie costume, it is found that she showed characteristics of symbolism(transmission of the sensitivity), ornamentalism(effective representation as a decorative effect attention) and multiculturalism(harmony of time and culture) as well as uniqueness. The movie costume are different mutually and create new hybrid culture, in which different costume cultures are mixed with current costumes without the restriction to other culture. It is proper for the age of globalization and localization so it is expected that the multiculturalism will be enlarged more.

우리나라 경찰은 지난 반세기동안 국내 외적인 시련을 극복하면서 질서유지자로서의 임무를 훌륭히 수행해 왔으나 최근 경찰을 둘러싼 환경은 국제화와 개방화, 민주화와 지방화, 산업화와 정보화가 급속히 전개되면서 치안수요의 폭발적 증가를 가져오고 있다. 또한 범죄유형이 날로 흉폭화 조직화 광역화 되는 추세여서 경찰 대응의 한계점과 더불어 장구 무기사용의 필요성이 대두되고 있는 실정이다. 하지만 장구와 무기 허용은 국민의 귀중한 생명을 위협할 수 있다는 선행과제로 인해 엄격하게 적용되어야 한다. 이에 본 연구에서는 기존에 경찰관들에게 지급된 장구 무기의 사용이 우리의 현실에 있어 실효성과 효과성이 있는지를 살펴보고, 일선 경찰관들의 법 집행력이 어느 범위여야 적정하고, 국민의 인권을 보호하는 경찰로서 신뢰를 받을 수 있는지를 조사하고 경찰 집행력 행사와 국민의 인권보호에 대해 방안을 제시하고자 한다.

The paper will present chip formation mechanism and surface integrity generation mechanism based on the systematical experimental tests. Some basic factors such as the end milling cutter tooth number, cutting forces, cutting temperature, cutting vibration the chip status, the surface roughness, the hardness distribution and the metallographic texture of the machined surface layer are involved. The chip formation mechanism is typical thermal plastic shear localization at high cutting speed with less number of shear ribbons and bigger shear angle than that at low speed, which means lack of chip deformation. The high cutting speed with much more cutting teeth will be beneficial to the reduction of cutting forces, enlarge machining stability mot depression of temperature increment anti-fatigability as well as surface roughness. The burrs always exist both at low cutting speed and at high cutting speed. So the deburring process should be arranged for milling titanium alloy in my case.

The way society works in the 21st century differs from that of 20th century, since the people are brought-up to speed regarding current technologies. The www.aflos.pe.kr site and direct e-mailing system were very useful in delivering floricultural information to extension educators, producers, and variety of individuals. The author’s one year experience indicated that extension educators and farmers are receptive to internet technologies, and extension educators have increased the knowledge base of their clientele by responding through direct e-mails. The internet and direct e-mailing systems were popular and powerful way of transferring floricultural information, especially agricultural extension manpower were limited because of localization of extension educators by changing national status to local governments and decreased number of extension educators through government restructuring. The direct e-mailing to approximately 503 individuals resulted about $1{\sim}3%$ responses and the number of phone calls, however virus protection software for e-mail, internet, file servers and desktops to provide the integrated real-time detection of viruses were needed. For more effective operation of direct e-mailing in the future, more specified target groups and specialized organization such as perennials, bulbs, flowering potted plants. and cut flowers. At the same time, things that have worked for last century should not be replaced with new technology, specifically, the value in one-on-one meetings should not be replaced, but rather serve as a supplement.

The presence of crust on the inner walls of metallic ducts impairs transportation because crust completely or partially hinders the passage of fluid to the processing unit and causes damage to equipment connected to the production line. Its localization is crucial. With the development of the electronic imaging system installed at the Argonauta/Nuclear Engineering Institute (IEN)/National Nuclear Energy Commission (CNEN) reactor, it became possible to visualize crust in the interior of metallic piping of small diameter using real-time neutron radiography images obtained with a low neutron flux. The obtained images showed the resistance offered by crust on the passage of water inside the pipe. No discrepancy of the flow profile at the bottom of the pipe, before the crust region, was registered. However, after the passage of liquid through the pipe, images of the disturbances of the flow were clear and discrepancies in the flow profile were steep. This shows that this technique added the assembled apparatus was efficient for the visualization of the crust and of the two-phase flows.
