UML is able to visualize and specialize the output of the system center of the software, and able to connect to various languages and is constructed by engineering/re-engineering. Also, UML is a standard Modeling Language that aims at the documentation. Recently Web Application System is quickly popular and gigantic, it's possible to do modeling using UML which is the method of Object-Oriented analysis and design and simplify the complex developing course of software. In this paper, we suggest the 『Post Seminar System』 model for instance Object-Oriented Web Application which can increase the efficiency of businesses through of exchanging information with members. We constitute web application by separating it into 3 steps such as View class which takes full charge of Screen Presentation, controller which plays the role of connecting ring and divergence of View class and Model class, and Model class that takes charge in the gear with the Application Logic and DB applying MVC model which has considerable merit in developing and maintaining the web application.

In this paper, a ferroelectric material BaTiO3 was added to SrTiO3, then (x)BaTiO3-(1-x)SrTiO3(0.7≤x≤1) ceramics were fabricated with stable electrical properties in high voltage. Microstructures and electrical properties were investigated according to mixing conditions of addition material SrTiO3. As a result of the investigation of all experiments, the shrinkage was excellent in 0.9BaTioO3-0.1SrTiO3. The grain size was increased, the curie temperature was shifted low temperature. The 0.9BaTiO3-0.1SrTiO3 was appeared stable property in temperature vs. permittivity. Also, 0.9BaTiO3-0.1SrTiO3 was showed stable dielectric properties at 25~85[C]. V-I properties of specimen were observed in the temperature range of 21~143[C], were divided into three regions. the region I below 10[kV/cm] was shown Ohmic conduction, the region II from 10 to 30[kV/cm] was explained by the poole-Frenkel emission theory and the region III above 30[kV/cm] was analysed by the tunneling effect.

Applied the high frequency switching technology to the ower conversion circuits, the turn on and off loss of switch point out practically large the point at issue, in order to reduce switching loss, the switching method using tank resonant circuit be connected serial and parallel with load have been continuously investigated. This paper was described about principle and form of proposed circuit made use of soft switching technology ZVS(Zero Voltage Switching) and ZCS(Zero Current Switching) to reduce turn on and off loss at switching. Also, the analysis of the proposed circuit is described generally by using normalized parameter and basic operating principle and driving characteristics have been evaluated as to switching frequency and load parameter. Based on the charactristics value, a method of circuit design is proposed. In addition, Pspice's simulation and experimental waveforms are compared with theoretical ones. The experimental results shows that the proposed Inverter can be used practically such as power source system for induction cooker etc.

정보통신산업 수출 및 가격변화의 파급효과 분석 : 2000년 산업연관표를 중심으로

정동진,정해식 정보통신정책학회 2004 정보통신정책연구 Vol.11 No.2

산업연관분석 틀을 이용하여, 90년대 이후 급속한 성장을 이루어낸 정보통신산업의 최근 구조 변화를 개략적으로 묘사하였다 '95년과 '00년 산업연관표의 비교를 통해서 분석한 IT산업 구조변화의 특징을 요약하면 다음과 같다. 먼저, 투입측면에서 중간재로서 IT산업의 역할이 보다 커졌다는 것이 다양한 지표로써 확인되어 부가가치 창출효과는 기대에 못 미치는 것으로 나타났다. 대신 수요측면에서는 투자수요와 수출수요가 IT산업 성장에 주도적인 역할을 하고 있다는 사실을 확인 할 수 있었다. 둘째, IT산업의 수입유발정도 및 수입의존도가 중가하고 있어 소재 및 부품의 국산화를 위한 지속적인 국내 연구개발 강화의 시급성을 재확인시키고 있다. 그러나 생산유발정도도 함께 증가하고 있고 수출의 증가율도 그에 못지 않게 높아서 수입유발 및 수입의존도에 대한 비판적 평가는 신숭을 기해야 할 것으로 보인다. 셋째, 수입가격의 변화가 미치는 파급효과는 크게 나타났다. 기기와 서비스의 경우 상당한 대조를 보였는데, 특히 부품 수입가격의 변화가 IT기기 부문에 커다란 파급효과를 가져왔다. 넷째, 환율의 변화는 대외경제에 민감한 IT산업의 특징을 반영하고 있었는데, 특히 부품에 미치는 파급효과가 큰 것으로 나타났다. IT 산업에서 부품의 생산 및 수출 비중은 예년에 비해 줄고 있지만, 위의 분석결과들은 아직까지도 IT산업의 중추적인 위치를 점하고 있다는 것을 보여주고 있다. This paper researches the recent structure changes of information technology industry which has grown rapidly since 1990's. The results with the comparison of 1995 and 2000 input-output table are the followings. First, the function of IT industry has increased as a intermediate goods in the input part, so the induced effects of value added in IT industry has not satisfied. Instead, the demand of investment and export play a leading role in the growth of IT industry. Second, we remind that the domestic R&D of IT components should be intensified as soon as possible. However, the critical view of increasing the import requirements should be prudential because the production requirements and rate of export have increased as much as the import requirements. Third, the multiplier' of the import price change has been very large. There are the considerable contrast between IT machinery and IT service. Especially, the import price change of IT components has influenced pervasively on the IT industry machinery. Finally, because IT industry is so sensitive to the foreign economy, the fluctuation of exchange rate has large effect on IT components. Although the production and export percentage of IT components in the IT industry has been decreasing, these results show that IT components yet play an important role in IT industry.

제주 4?3 사건은 약 7년 동안 남북한 정권, 민간인, 미국 등 서구 열강의 힘 등이 복합적으로 작용해 숱한 사람들이 사망한 사건이다. 4?3 사건을 둘러싼 논의와 갈등들은 한국 근현대사의 문제들과 닿아 있으며 4?3 사건과 그 진상규명과정에서 파생한 갈등들, 한국사회에서 4?3 사건이 기억되는 맥락은 매우 복합적인 결을 지니고 있다. 본 연구는 4?3 사건을 두고 일어나는 기억의 의미투쟁 현장을 신문은 어떻게, 얼마나 보도하고 있는가를 고찰하고자 했으며 이를 위해 1999년부터 2013년까지 14년 동안 경향신문 동아일보 조선일보 한겨레신문(가나다순) 기사 중 4?3 위주로 보도된 654건의 연도별 보도량과 주제, 기사의 의미와 기사 속 행위자 등을 분석하여 미디어 기억이 어떤 이야기를 하고 있는지 살펴봤다. 4?3을 둘러싼 최근 14년간의 뉴스미디어의 기억 지형을 살펴본 바, 사회적으로 드러난 4?3사건을 둘러싼 중요한 이슈 지점들과 4?3사건을 기억하는 미디어의 기억 지형에서 나타나는 중요한 순간들은 일치하지 않았으며 언론은 지엽적이고 파편적이며 정치 ‘싸움’에 집중된 갈등적인 요소들을 두드러지게 부각시키고 있었다. 무엇보다 4?3사건이 지니고 있는 본질적인 갈등양상과 뉴스미디어에서 그려내고 있는 갈등의 내용과 모습은 큰 차이를 보이고 있으며 뉴스미디어를 통해 이뤄지고 있는 기억전쟁은 왜곡된 형태를 지니고 있는 것으로 드러났다. The Jeju April 3(4?3) Incident occurred during seven years, from 1947 to 1954 in the island of Jeju. Two separated Korean governments, Korean civilians, United States of America and the other actors were complexly related to the incident and 25,000 casualties were estimated. The ongoing discussion and conflict regarding the 4?3 incident is still controversial and the context in which the incident is remembered in Korean society is complicated. Considering the complex nature of the Jeju April 3 Incident, this Study examined the mnemonic battle in Korean newsmedia, how Korean newsmedia covered this incident last fourteen years. For this study, four Korean daily newspapers- Kyunhyang, Dong-A, Chosun and Hanguerae were selected and 654 articles directly related to the incident were collected and analysed. Consequently the main issues and important moments of the 4?3 incident exposed in society and in newsmedia were in discord and inconsistent. The newsmedia covering the incident focused on peripheral issues, fragmented memories and minor conflicts instead of the essence of the incident, and therefore distorted the nature of it.

Strain type of lactic acid bacteria was analysed by PCR and SDS-PAGE. PCR allows the rapid and specific detection of lactic acid bacteria using primers based on 16S rRNA gene-sequences. The analysis of protein pattern on SDS-PAGE can be used to determine the differences among the same or similar species of lactic acid bacteria. Therefore, the complementary use of PCR and SDS-PAGE method is one of simple way to classify the lactic acid bacteria and to compare with genetic analysis.
