  • This paper contains that the current emergency response procedure through the railroad accident type at domestic and foreign, and the response program which is more systematic as a result of improving weaknesses. Because the response program at home is less sufficient than developed country's, we have made an investigation into system of classification in America, British, Germany, Japan for organizing separate emergency response code. we have researched the recognition response of five senses for minimizing the accident damage in a way of spreading the emergency response type analyzed through the accident procedure according to the feature of five senses by the first recognizer. Based on the first recognitions response of five senses, the scenario has been established according to each types and the criteria of accident has been researched through classifying the recognition of five senses response level, early response level, self-response level, outside support level.

  • Many years ago, most of thermal power plants built in this country were of subcritical pressure, of medium or small size, of constant pressure operations and of drum type steam generators with circulation type boilers. But, nowadays almost all of them were of high efficiency, of supercritical pressure, of big capacity, of sliding pressure operations, and of once through type steam generators. Presently built once through boilers introduce turbine bypass systems to variable pressure operation which eliminates unexpected materials in boiler tube during startup, minimizes fuel loss by short startup period and eventually improve both total efficiency and power system stability.

  • This paper is to cluster the AMR (Automatic Meter Reading) data. The load survey system has been applied to record the power consumption of sampling the contract assortment in KEPRI AMR. The effect of the contract assortment change to the customer power consumption is determined by executing the clustering on the load survey results. We can supply the power to customer according to usage to the analysis cluster. The Korea a class of the electricity supply type is less than other country. Because of the Korea electricity markets exists one electricity provider. Need to further divide of electricity supply type for more efficient supply. We are found pattern that is different from supplied type to customer. Out experiment use the Clementine which data mining tools.

  • This paper presents the results of an empirical study on the relationship between the type of new product idea sources and the rate of success of new product development and commercialization in Korean industries. The sample was taken from various Korean industries including telecommunication, electronics, chemical, machinery, textile, etc. and composed of 45 failure and 73 success cases. The findings are not much different from those of previous studies done in the developed countries, but show some typical characteristics of new product development activities and the idea sources, information acquisition methods, type of information , incentives for idea generation, etc. of the firms in developing country like Korea. Especially the survival rate curve and the accumulative investment curve from the idea generation to commercialization phase show a little different behavior from the previous study, which also reflect the manpower, duration of each phase of the new product development process in the Korean firms.

  • The main purpose of this research project is to monitor the present state of agricultural environment and to develope the countermeasures for the protection of the environment from the pollution by animal wastes. The results of this research were described largely 3 parts, 1) Monitoring of present state of environmental pollution by animal wastes, 2) Monitoring of animal wastes treatment technology, 3) Strategies for the protection of environmental pollution from animal wastes in future. The current most important problems from animal wastes are water pollution and air pollution commonly regardless of domestic or foreign country. Especially, intensive livestocks breeding pattern in restricted area is actually a real reason of eutrophication, soil acidification, ground water contamination, irrigation water pollution. As a result from this research project, authors recommend the 3 type of strategies for the protection of environmental pollution by animal wastes, 1 . Development of non-discharge type of wastes treatment technology 2. Manufacturing local structure for animal waste recycling system 3. Development of new international environmental program for transfer bioresource and soil environment prevention.

  • This paper presents design conditions due to the NTU of counter and cross flow type cooling tower. In the calculation of optimum design conditions for above two types which are widely used in our country, standard water-air ratio, ambient wet bulb temperature and bulk water temperature were adopted by domestic wheather conditions. The important result of this study is obtained as follows : Under the constant value of Ka and L, the number of transfer unit of cross flow type cooling tower Is about 1.1 times as large as that of counter, so the volume of cross flow type is about $10\%$ greater than that of counter.

  • The objective of this study is to examine Korean fisheries' globalization level. For that, this paper discusses structural changes of world fisheries and level of korean fisheries' globalization. Fisheries' globalization is measured by comparison of IIT(intra-industry trade) and LIT(level of international trade) on eleven countries(Netherland, UK., USA, France, Japan, Spain, Korea, Taiwan, Thailand, Indonesia, Philipinnes). And analysis data are obtained from UN-UNCTAD PC-TAS and FAO Fishstat. As a result of measure of fisheries' globalization, Netherland is the most globalization country of eleven countries. And the next order is Spain, UK, France, Thailand, Taiwan etc. We can classify these countries into four types. Type I is 'International linkage and integration global indutstry' inculding Netherland, UK, Spain, France. Type II is 'Interantional integration global industry' including Taiwan and S. korea. Type III is 'international linkage global industry' including none of eleven countries. Finally, type IV is 'domestic demand and self-sufficient industry'including Thailand, USA, Japan. So we can name the type of korean fisheries' globalization as 'interantional integration global industry'. Usually this type is evaluated that level of international trade is not high but level of intra-industry trade is high. As a result, from now, we should consider policy directions of korean fisheries whether to decide one of four types or not.

  • 마우나 리조트 붕괴사고, 세월호 침몰사고 등 대형 재난사고들이 발생하였을 때 체계적이지 못한 현장대응과 응급의료시설의 운영으로 인해 재난발생 시 현장에서의 체계적인 응급의료서비스의 필요성이 대두되고 있다. 재난, 재해 발생 시 적절한 시간 내에 안정적인 응급의료서비스가 제공 된다면 2차적인 피해를 줄일 수 있으며 피해에 대한 복구도 신속하게 이루어 질 수 있다. 따라서 다양한 재난의 피해유형과 규모에 맞추어 신속하고 안전하게 재난현장에 대응 할 수 있는 응급의료체계가 구축될 필요가 있다. 이를 위해 현재 국내, 외 사례들을 조사하여 이동 의료단위의 유형을 파악하고, 규모별 분석을 실시한 결과 국외에는 트레일러유형, 텐트유형, 컨테이너유형 등의 이동 의료단위들이 실제 운용되고 있었으며 국내에서는 그러한 운용 사례들을 조사하고 종합하여 정부에 제안하는 단계에 있다. 국내에 적합한 이동형 의료단위의 개발과 제안을 위해 실제운용 사례들의 단위유형, 규모 및 조합적 배치에 대한 심층적인 분석을 토대로 국내에 적절한 유형을 제시한다.

  • 1. Objectives Recently there have been studied the trials to take out the characteristics of Sasangin's face. 3 dimensional modeling is essential to find out sasangin's face. So the studies of standard face model and face type are necessary. 2. Methods I have reviewed the researches of standard facial modeling and facial type in the inside and outside of the country. 3. Results and Conclusions The Facial Definition Parameters are a very complex set of parameters defined by MPEG-4. It has defineds set of 84 feature points and 68 Facial Animation Parameters. Face type has been researched to divide into male and female, or the westerns and the orientals, or sasangin(Taeyangin, Taeumin, Soyangin, Soeumin).
