The underground equipment is needed inevitably in the large city, therefore the underground cable will be much used gradually at transmission line as well as distribution line. Lately, with the technique growth of XLPE cable, the Voltage of 500kV level is used commonly in japan, manufactory within a country is developing in itself also Considering that the accidents of CV cabale due to "degradation" happened on and on in lately report, the "degradation" measurement of cable is very important. But the research of the cable is insufficent. So in this thesis. The XLPE (Crosslinked polyethylene) insulation cable mainly uses underground cable which electronic, mechanic, chemical's characteristic is superior and also heat-resistance is superior It is the main current of Power Cable. However, we don't have a countermeasure to protect insulation cable from trouble occurring continuously by reason of deterioration on present time. For that reason, it is very important that diagnosis of cable's deterioration. But, the researching of reliance cable's ability estimation or method of deterioration diagnosis are weak. Therefore, in this study through the analysis of underground power transmission cable's trouble in that time we researched the reason of XLPE cable's deterioration and the main reason are substance, type of protrusion making trouble. I studied the thermal energy by underground cable's thermal degradation characteristic test and I considered to electronic characteristic for raising reliance. Electrical tree initiation stress by insulation inserted needle in less than 5㎛ radius "by pre-breakdown partial discharge detecting method suddenly increases and that of XLPE cable manufactured in korea is more than 290kv/mm. As a result, creation in cable insulation, the moisture is harmful influence to insulation ability with the passage of time. And as known it is occurring electronic breakdown which if the section stress excess the limit value of moisture. And the ageing cable by partial discharge and light of UV is most lower of thermal breakdown intensity for that reason, it influences to XLPE life span directly.

인터넷은 다양한 정보를 접할 수 있게 해 주었고, 지금까지와는 다른 형태의 만남-이메일, 채팅, 게시판, 인터넷 동우회 등-을 가능하게 하여 인간 상호 이해의 폭을 넓혀 주는 기회를 만들어 주었다. 또한, 제한된 정보만을 수용하던 형태에서 벗어나 많은 양의 정보를 주체적으로 처리할 수 있는 능력을 키워주고, 정보의 홍수시대를 살아가는 방법을 스스로 체득할 수 있게 해 주었다. 그러나, 인터넷은 순기능 못지않게 역기능 내지 폐해 또한 심각한 상태로까지 치닫고 있다. 일부 청소년들에게 있어서 컴퓨터 사용이 게임이나 오락, 음란물 등의 목적으로 편중되어 나타나고 있고, 컴퓨터의 장시간 사용과 지나친 몰두로 인해 신체적, 심리적 문제 등 많은 현실 부적응적인 문제들을 야기하고 있다. 그러므로 정보화의 역기능적 측면에 대한 대응책 마련이 시급하다는 사회적 요구 또한 증대되고 있는 실정이다. 본 연구는 중학생을 대상으로 인터넷을 이용한 채팅과 게임부분의 중독 상태를 진단할 수 있는 문항과 치료할 수 있는 적절한 교육과정을 개발하여, 이를 이행함으로써 스스로 감찰하고 조절할 수 있도록 돕는 웹 컨텐츠를 설계하고 구현하여 실제 온라인 실시간 방식으로 학생들에게 적용시켜 결과를 분석하고자 하는 것이다. 본 연구의 목적을 달성하기 위하여 채팅과 게임 중독 진단에 관련된 20개 문항과 종합적인 중독 문항 5개, 교육과정을 개발하여 웹 컨텐츠를 설계하고 구현하여 중학생들에게 실제로 적용시켰다. 진단 결과에 따라 상, 중, 하 3가지의 교육과정 중에 해당하는 교육과정을 한 달 동안 이수한 후 최종 진단 결과를 분석하였다. 학생들은 이 프로그램을 이용하여 인터넷 중독에 대한 경각심을 갖고, 인터넷 중독을 스스로 진단하고, 매일 자신의 일과를 반성하고, 스스로 계획을 세워 지키는 것을 해봄으로써 충분히 중독에서 벗어나 확고한 목적의식을 가지고 건전하게 인터넷을 활용할 것으로 기대된다. Internet has contributed to enhanced understanding between people by providing a variety of information and whole new ways of meeting-emails, chatting, BBS, and Internet clubs, etc. It also has served to cultivate our ability to actively process greater amount of information, departing from the previous way of adopting limited information and learn by ourselves how to survive in this age of overflowing information. However, there have been growing serious malfunctions and bad effects of the Internet in spite of a number of its benefits. Some teens tend to use computers mainly for games, entertainments or viewing pornographies, while longer use of and excessive indulging in Internet causes enormous problems of maladjustment to reality including physical and psychological problems. Therefore, there are increasing demands for urgent actions to encounter malfunctions of digitalization. This study aims to design and realize web-contents for the purpose of developing a scale containing items for middle school students to diagnose their addiction level of Internet chatting and games as well as appropriate educational programs to treat such addiction in order to help students monitor themselves and adjust, and then analyze the results after on-line real-time based application to students. To that end, a scale consisting of 20 chatting and game addiction-related items and 5 comprehensive addition-related items and educational programs were developed, with web-contents to be applied to middle school students being designed and realized. Based on the results of diagnosis, among 3 types of educational programs dividing into advanced, intermediate and lower levels, final diagnosis results were analyzed after a month’s implementation of suitable programs for each case. This program is expected to help students realize the dangers of Internet addiction, free from Internet addiction with a firm goal, and use Internet more constructively, by having them diagnose for themselves, reflect daily activities, and set goals and put into practice on their own.

This study evaluated the process characteristics of step feed 5-stage pilot plant(55㎥/d) in BNR(biological nutrient removal) process, such as the influent ratio, the effect of dPAOs(de-nitrifying phosphorus accumulating organisms) and temperature. In order to apply the microbial community in the process for operating and management as well as design, were using DAPI and FISH and 16s-rRNA for the pilot plant. The maximum removal efficiencies of T-N and T-P were 80% and 83% when split ratio of Influent(Pre-ax: An: Ax-2 tank) was 1:6:3. The concentration of effluent were 8.0 mg/L-N and 0.7 mg/L-PO_(4)-P. As a result of step feed system operation, HRT was reduced mainly due to high concentration of MLSS, low yield, oxygen saved in oxic tank and high SNR. In the investigation of temperature effect, nitrification-denitrification rate at 10℃ was decreased to 1/3 and 1/4 based on the condition at 20℃. However phosphorous removal was independent of temperature resulting in 4.7 mgSP/L of removal potential. DPAOs fraction in PAOs was 55∼70%(average 60%). Contribution of dPAOs for de-nitrification was 5∼26% and for saved oxygen requirement was 0.5∼4.3%. In the anoxic-1 tank, COD saving by dPAOs was 41% (2.4gCOD/gNO_(3)-N) for denitrification. Based on the result from temperature at 20℃, specific phosphate uptake rate at 11∼15℃ decreased in the oxic tank and the anoxic-1 tank, 76%, 30.5% respectively. DPAOs showed a greater temperature effect than that of PAOs for phosphate uptake. From DAPI analysis, both in anoxic-1 and oxic stage, PAOs remained relatively high at 50% and 45%. From the dual staining comparison with FISH and 16s RNA, dominant groups that may be considered to be PAOs were high G+C gram positive bacteria group and Cytophaga-Flavobacterium group, the proportion was calculated from 15.8∼18.8% at minimum.

These phenomenon are happening to if not all, many small to medium size companies. In 1995, international community has agreed to lower trade barriers to promote free trade markets. Despite WTO agreements, many countries have heightened their technical barriers using standards of quality, safety, health, and environment as means. Especially, developed countries, using their technical advantage, are demanding to meet international environment standards, which could have an enormous influence to those under-developed countries. This kind of movement is seen also in product certification, making certification of international standards one of the most significant factor. In Korea, before Asian financial crises of 1997, among 53 prominent international standards by 24 countries, Korean companies received only 15 types of international certification in 11 countries. Among those 25,000 small & medium export/import companies, only 7.2% acquired various international certifications, which resulted in reduction of exports of 20.5 billion U.S. dollars With International Standards and Certification, becoming a new export barrier, getting international certification is rapidly becoming a must requirement for companies, which export, and this also translates to their competitiveness in the world market. Having these kinds of certifications can also help companies to promote more controlled quality assurance system within the production and provides consumers with increased assurances that what they buy is what they get from the objective point of view. Certification process carried out by government assess whether companys system, products, and technology are complying to those appropriate standards With the development of communication and Internet technology, geographical position and political border no more work as trade barrier and make nationality of company have less importance. And all these movements drive multi-national company to try to find the most appropriate place where they can combine key products elements such as manpower, capital, technology, and drive world markets into severe, limitless-competition. In spite of, current economic environment, new barriers are rising under the name of security of nation's people. Such barriers are as follows; -Frequent lawsuit of Anti-dumping, countervailing duty from those developed countries - Enforcement of import restrictions to help their own economic difficulty on the expense of those under developed countries -Adopting various standards, and technical specifications as technology barriers -Increased barriers in environmental protection. Almost every country enforces certification system to help nation's people enjoy sound consumption without being threatened people's body and life. So to overcome problems from trade barriers and to make new 21st century exemplary model for small & medium companies' competition, this thesis will research following subjects; 1) Study characteristics, economic environment of small and medium companies in Korea as well as importance of changing in business environment . 2) Under the new paradigm, how small & medium companies can adapt to ever changing international quality standard and to improve their competitiveness and to maximize the effects after meeting those standards. 3) Research and analyze small & medium companies 4) Present exemplary model of small & medium companies by studying quality and environment managing, and its effects on trade.

박종복 한국해양대학교 해사산업대학원 2004 국내석사

Since the invention of internal combustion engine, various kinds of diesel engines were developed for the demands and requirements of industry. The reason for the adoption of diesel engine is the fact that it can accommodate many requirements of modern ship propulsion system. There were non-interrupted research and development in accordance with the applications and necessities required by many areas ranging small engines for agricultural uses and industrial uses, diesel engines of 50 to 550BHP for motors, some hundreds to 2,000BHP for trains, and 10,000 to over 100,000BHP for large ships. The performance of the engine can be distinguished by economic, conductive performance and environmental affinity. Conductive performance can be mentioned as credibility, maintenance management, minimization of components numbers, usage of lower grade heavy oil. And the economic performance means conductive expenses, conductive life, initial investment, minimization of weight, flexibility of installation. Conductive expenses include the factors resulted by thermodynamic characteristics such as heat efficiency and fuel consumption. With this reason such as economic consideration, over 95 percent of the modern world commercial ships and navy vessels gain propulsion by Diesel engines. Therefore, consideration of security, economy, and environmental affinity will be the direction of the development from now on. And performance renewed consistently and finally reached current level. with a review of the process of development carried out up to now, characteristics of the diesel engine can be optimized as follows (1) Grass-cutters, which is portable and super small-sized, 2-stroke gasoline engines are used as the power engines. The major reason is that they are simple in structure and light in weight. (2) Little HP power engines, which is used for cars and ocean leisure, 4-stroke gasoline engines are used because they are comfortable with a small tremble. (3) Little HP power engines for industrial uses are 4-stroke diesel engines. The reason includes the economic consideration, which is superior in fuel consumption, or heat efficiency. (4) Medium HP power engines for industrial uses are both 4-stroke and 2-stroke diesel engines. It is because of the major consideration of economic propriety. (5) For the merchant large ships 2-stroke diesel engines are used. The major consideration is lower fuel consumption and capability of lower-grade heavy oil application. And also cross-head engines are used, respectably. As shown above, the structures of the engines are discernable by their application. Therefore, 2-stroke, 4-stroke, gasoline and diesel engines have distinct characteristics and have developed to optimize their superiority. But in the range of medium sized HP, the range of the 2-stroke and 4-stroke engines are overlapping. To select the power engine in this range properly, the quantitative comparison and analysis of the characteristics in the range are need. The characteristics of the engines can not be said simply, because they can be considered in many different view points. But it is necessary to make characteristics distinctive by comparative analysis in many different views, which can be usefully applicant to the collective judgement in the selection of a proper engine. In this research, we will make a comparative approach which is restricted to the output performance in the view of thermodynamic cycle.
