This study aims to examine the costumes, which a shaman wears for the ritual of exorcism in the Honam region. The findings are based on a field survey of the exorcism ritual, which is performed by hereditary shamans and forms part of an annual event in the Honam region. Two main features of the shamans' costumes were observed. Firstly, the types of shamanic costume worn for gut reflected the general traditional costume but with some variations. White-colored costumes are largely found in the Honam region. Secondly, the types of costumes, which shamans wear in the Honam region. are also varied. The different types of shamanic costumes, regardless of Ga-sa, can be classified into Jang-sam, Jeon-bok, or Duru-magi, variations in the patterns of costumes, differences in the types of conical hat, and modifications in the dress code.

There are many issues in computer simulation such as verifying model code, validating models, understanding the dynamics of systems and training the personnel. The developers of simulation tool have been interested in the animation since it can help solve the problems related to the above listed issues. In practice, animation is one of the popular method for displaying the simulation output for solving these problems. Trying to display all the graphic objects representing the dynamics of the models being simulated, however, causes the distraction of focus, which results in solving the above listed problems difficult. The redundant graphic objects also Increase the computer computation overhead. This paper presents a hierarchical animation environment in which the users can have better focus on the dynamics of system components. In hierarchical animation environment the users can observe the dynamics of system by selectively choosing the hierarchical level and components with in a level of the hierarchically structured model. Especially when the model is large and complex the selection of observation level is needed. The design approach of the hierarchical animator is based on the DEVS(Discrete Event system Specification) formalism which is theoretically well grounded means of expressing modular and hierarchical models.

본 연구에서는 극 저 에너지 이온 주입에 관한 연구를 위하여 새로이 제안된 PLDAM(phenomenological local damage accumulation model)을 효과적인 분자동역학 이온 주입 분포 계산 방법(highly efficient molecular dynamics (MD) schemes)에 적용하여 극 저 에너지 이온 주입에 관하여 연구하였다. PLDAM은 셀에 축적된 에너지와 이온 발생 순서(history of recoil event) 및 열 전도를 고려하여 실리콘 자기 이완과 재결합을 고려하고 있다. 효과적인 분자동역학 이온 주입방법으로는 MDRANGE code를 사용하였다. 국부적인 격자결함을 고려하지 않은 MDRANGE의 결과는 불순물 분포의 실험치와 꼬리 부분에서 많은 차이를 보여주었다. 그러나 본 연구에서 사용된 국부적인 격자결함 축적을 고려한 MDRANGE의 결과는 극 저 에너지 이온 주입 실험치와 잘 일치하였다. 또한 본 연구에서는 <100> 실리콘 기판 위의 0.1$\mu\textrm{m}$$\times$0.1$\mu\textrm{m}$ 영역에 도즈에 해당하는 이온만큼을 주입하여 불순물 분포를 계산하였다. 붕소와 비소의 경우에, 도즈와 이온주입 에너지가 증가하에 따라서 국부적으로 축적된 격자결함이 불순물의 분포에 미치는 영향이 커지는 것을 알 수 있었다. 특별히 이온 주입 에너지와 함께 무관하게 도즈 1014/cm2 이상에서는 국부적으로 축적된 격자 결함이 불순물의 분포에 크게 영향을 미치는 것으로 나타났다.

Purpose - The purpose of this paper is to examine IKEA in the context of corporate social responsibility to determine the reasons, if any, as to why IKEA has had more success in the implementation of its CSR policies and Code of Conduct where many other multinational companies seem to have failed. Research Design and Methodology - This is a case study, an analytical approach, which focuses on exploring and analyzing the CSR policies to measure IKEA's ethical behavior in a business environment. Results - IKEA stands out as a multinational company whose CSR policies are ingrained into the business itself as a part of its ethical operations, rather than a marketing event. Conclusion - Beyond profit, IKEA actively works together with its suppliers and the nation states to eradicate the harmful social causes of the various challenges it faces in the global business environment.

The most popular regression model for the analysis of time-to-event data is the Cox proportional hazards model. While the model specifies a parametric relationship between the hazard function and the predictor variables, there is no specification regarding the form of the baseline hazard function. A critical assumption of the Cox model, however, is the proportional hazards assumption: when the predictor variables do not vary over time, the hazard ratio comparing any two observations is constant with respect to time. Therefore, to perform credible estimation and inference, one must first assess whether the proportional hazards assumption is reasonable. As with other regression techniques, it is also essential to examine whether appropriate functional forms of the predictor variables have been used, and whether there are any outlying or influential observations. This article reviews diagnostic methods for assessing goodness-of-fit for the Cox proportional hazards model. We illustrate these methods with a case-study using available R functions, and provide complete R code for a simulated example as a supplement.

This paper is intended to trace and management of a medical specimen and its report in a hospital. To avoid missing and decaying specimen and to establish of order in the circulation of specimen, at the moment sampling, RFID tags for each are on examiner. And then, specimen is monitored easily, quickly and, correctly. We developed implementation LIS system has better CQI (Continuos Quality Improvement) using RFID and XML, ADO.net, ASP.net, C# 2.0. RFID technology replaces to an existing the bar-code system. Also for more convenience, we used a PDA-RFID module. The LIS system consists of main sorrel, SQL 2005, event display and analysis web page developed using asp.net 2.0 and sharing specimen data information using XML technology.

Maize mitochondrial tRNAs for isoleucine have been isolated using a putative $tRNA^{Ile}$ gene probe which has been previously isolated and characterized. It contains the 5'-CAT anticodon which would normally recognize the AUG methionine codon. The nucleotide sequence of one of these tRNAs has been partially determined, and contains a modified nucleotide at the first position of the anticodon. This type of posttranscriptional modification event could change the specificity of amino acid acceptance of a tRNA, unlike that deduced from the corresponding gene. An aminoacylation experiment also demonstrated that these purified tRNAs have isoleucine acceptance activity but no methionine-accepting activity.

The ladder diagram (LD) for programmable logic controllers (PLCs) ar responsible for much important roles in advance industrial automation. As automated systems become more complex the design procedures of the system become more difficult as well. Hence. the design automation issues based on discrete event models(DEMs) are receiving more attention. One of the popular ways of tackling these problems is employing Petri nets. In this paper, we use the modified automation Petri net(MAPN) to model the manufacturing system and the modified token passing logic (MTPL) method conversion (ECC) algorithm based on the MAPN and the MTPL Finally, an example of the manufacturing system is provided to illustrate the proposed ECC algorithm.

Background: As one of the most frequently occurring accidents in a chemical plant, a fire accident may occur at any place where transfer or handling of combustible materials is routinely performed. Methods: In particular, a jet fire incident in a chemical plant operated under high pressure may bring severe damage. To review this event numerically, Computational Fluid Dynamics methodology was used to simulate a jet fire at a pipe of a compressor under high pressure. Results: For jet fire simulation, the Kemeleon FireEx Code was used, and results of this simulation showed that a structure and installations located within the shelter of a compressor received serious damage. Conclusion: The results confirmed that a jet fire may create a domino effect that could cause an accident aside from the secondary chemical accident.

We present elemental abundances of 95 blue compact dwarf galaxies (BCDs) at z=0.2~0.35 using the Sloan Digital Sky Survey (SDSS) DR7. We derived element abundances using Te method. We found that nitrogen abundance of merging BCDs are more enriched than normal BCDs by fast rotating young massive star. On the other hand, neon and oxygen abundances for merging BCDs are slightly lower than the normal BCDs. This might be result from the dilution by metal-poor gas infall during the interaction. This means that merging BCDs undergone star formation event for a long time than normal BCDs and we trying to explain using STARLIGHT code and various star formation rates (SFRs) ratios. At a result, merging BCDs have older stellar population (>10 Myr) more than normal BCDs and have clear distinction in elements abundances versus Ha/UV diagram. We also discuss the characteristics of post merger candidate using FUV to NUV ratios.
