A design pattern is a general reusable solution to a commonly occurring problem in software design. A design pattern is not a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations. Moreover, the name of pattern itself also can be a kind of common language among developers and patterns can be easily imported to various applications demanding similar requirements. In this paper, we present models of CBTC onboard system which follows ERTMS/ETCS specifications and present patterns applied to our system.

Polyvinylchloride(PVC) is variously used to produce food packaging, wrap film, sealing compound of drinking bottle cap. Safety of these PVC food package is controlled by Food Code, PVC regulation. This study was carried out researches on manufacture process, physical, chemical properties and monomer(CAS No., common name, molecular structure) of PVC to help the understanding of PVC material. Also, this study helps us the understanding of regulation through researches on the foundation of PVC regulation, the purpose of test and the comment of test method. It is considered that these informations of material properties and explanations of test method are very useful to PVC producers, users and analyzers of them.

The purpose of this article is to introduce a useful methodology of effective goal-setting for the team-level units. As a way to overcome some common symptoms in terms of Strategic Performance Evaluation System such as lack of knowledge on goal-setting, disconnection of process, problem of judging the degree of difficulty about objectives, limits of staff departments evaluation, fairness and authority of evaluators, weakness in coaching technique, and quantity or figure-oriented evaluation, to name a few, and to seek a more plausible goal-setting methodology, the author suggests a persuasive goal-setting concept: VAR(Value-Added Results). VAR, as the end-results, is the team contributions that add value to the organization, and it results from the team's activities. In addition to these goal-setting technique based on the concept of value-added results, several aspects should be improved for Strategic Performance Evaluation System to be implemented more effectively. They are: 1) shift from MBO to MP & D(Managing Performance & Development), 2) impartial exercise of evaluation authority as a organizational public assets, 3) reinforcement of maternal leadership and servantship instead of paternal leadership, 4) utilization of IT-based evaluation system.

The purpose of this study is to analyze Adolescents spending habits and examine it. The data was collected from 1125 high school students and their parents nationwide. The resets are as follows. 1. About seventy eight percent of the responded students own relatively high-priced goods such as brand-name jeans (59.1%), a mobile phone (31.9%), perfume with a price of 50,000 won or more (26.5%), CD Player (24.4%) or electronic pocket diary (17.1%). The percentage varies according to region. 2. The Adolescents tendency for conspicuous consumption is reflected by 2.92 points out of a total 5 points, while their mothers'marks 2.18 points. By region, conspicuous consumption behavior is more common in Seoul than in other small and medium-sized cities and towns. Also, the more mother attribute children's behavior internally, the lower the childeren's competence is.

This paper presents the program to analyze an antenna for using the Moment Method. The program contains three different functional steps. In the first stage, the pre-processor is based on the Delaunay Triangulation Algorithm. The next stage, the main-processor, can be considered the core process of the program, which solutions are obtaining the linear matrix for using the Moment Method. The final stages, the name of the post-processor, analyze radiation patterns, which results are same with the S-parameters. The results demonstrate satisfactory agreement with the results for using other numerical packages and measurement data. We can confirm that the results of this program compare with the results of common program to analyze for an antenna.

The most common cause of spontaneous pneumothorax is a ruptured bleb, which occurs mostly in young patients and they are usually treated by tube thoracostomy. Recurrence frequently occurs and these patients require some form of surgical intervention. From March 1990 to February 1994, we have experienced 19 cases of recurrent pneumothorax in 16 patients among 347 patients who underwent 423 surgical interventions. The name of first operation after thoracotomy were bullectomy in 4 cases, bullectomy and pleurodesis in 3 cases, bullectomy, pleurodesis in addition to application of tissue sealant in 1 case. Thoracoscopic operations were performed as follows: bullectomy in 2 cases,electroablation plus tissue sealant in 4 cases, electroablation, tissue sealant and pleurodesis in 1 case,and in 4 cases, only tissue sealant was applied. The average age of patients are 21.5 years, and bilaterally operated patients and patients. who received tissue sealant or tissue sealant plus electrocauterization only had higher incidence of recurrence. The patients who needed chest tube insertion longer than 5 days after the first operation were 52.6 %, and 82.3 % recurred within one month of the first operation.

The ontological status of Newtonian space-time has been debated under the name of substantivalism-relationism controversy. The debates between the two parties are concerned with the nature of existence of space-time. Substantivalism maintains that the points of space-time have existence analogous to material substance. Relationism claims that space-time should be understood as the framework of possible spatio-temporal relations between bodies. Newtonian space is considered as a three dimensional entity in accordance with our geometric common sense. Yet given that the concept of motion is defined as the change of position throughout time, it is possible to interpret space-time as a 4 dimensional entity. In this essay, substantivalist-relationist debate is considered within the context of non-relativistic 4 dimensional space-time theory. This essay attempts to clarify the dispute over the ontology of space-time by elucidating the relationship between the ontology of space-time, motion, and space-time symmetry.
