  The fable, 〈Yoenorang and Seonye〉 is the myth of the Sun and the Moon. Because the periodic and the geographic backgrounds are very well known and the main characters are connected with the movements of the Sun and the Moon. This fables is the only myth about the Sun and the Moon in the Korean literature, but it is rarely studied in the teaching methodology. So this study tries to analyze the structure and the meaning of this fable, and suggest the proper teaching methodology to the characteristic of the myth.<BR>  In chapter Ⅱ, the paragraphs in this fable are arranged according to the time sequences. This fable has a spiral structure by repeating the deficiency and its elimination two times.<BR>  The first deficiency is the situation that the common husband and wife are separated by the absolute power. This is solved by the wife"s rejoining the husband in Japan. The second deficiency is the situation that the absence of Yoenorang and Seonye made the Sun light and the Moon light disappeared in Silla. It is also solved by the religious procedure with the holly robes to Silla.<BR>  In chapter Ⅲ, this fable is inquired into the relations between the meaning as the sun-and-moon myth and the important motive, the religious procedure. And I found out the meaning of "Nippon(Japan)" and the relations between its meaning and Japanese myths.<BR>  The fable, 〈Yoenorang and Seonye〉 is the story that the common persons, Yoenorang and Seonye are sublimated into the spirits of the Sun and the Moon and they helped to get over the national chaos. This means that the religious belief in the sun and the moon is reflected in this fable as a myth. Nippon(Japan) where Yoenorang and Seonye are rejoined and settled down can be explained where the spirits of the sun and the moon are settled. Their absence made the darkness in Silla at day and at night, and the silk holly robes which Seonye wove got the lights back to Silla. This means they were in very holly place and never got back to Silla.<BR>  Considering the Japanese birth myth, they have the common thing that the woman is symbolized as the Spirit of the Sun. The myths of Silla and Japan are related each other, but it"s hard to say that they are directly related each other.<BR>  The religious procedure for the Spirits of the Sun and the Moon is the important solution in this fable, 〈Yoenorang and Seonye〉. The place where this story happened has a long history of the religious belief in the Sun and the Moon. And we can guess that in this place many religious procedures have been happened to worship for the heaven, the Sun and the Moon. In this fable, the solar eclipse symbolized uneasiness political situation, and the religious procedure with holly robes is the efforts to overcome the national chaos.<BR>  In chapter Ⅳ, the fable, 〈Yoenorang and Seonye〉 is considered for the educational values and Teaching methodology is suggested to supplement the problems of the current educational curriculums. Teaching the myth aims to promote the children"s imaginations. The lesson plans are consisted of the ventilation for the imaginations, the imagination configurations, the imagination extension and the imagination settlement from the characteristics of the myths. In the step of the imagination configurations, teachers should explain the historic, geographic and folkloristic backgrounds to the children. These teacher"s role guide them to promote and enlarge their imaginations to understand the myth better.

2000년대 온라인 게임이 급격하게 성장하면서부터 온라인 게임 및 아이템 거래가 사이버 범죄 등을 발생시키는 주요 요인이라는 견해가 존재하였다. 그러나 정말로 온라인 게임 및 아이템 거래가 범죄 증가와 관련이 있는가에 대해서는 그동안 실증적 연구가 이루어지지 못하였다. 본 연구에서는 온라인 게임 및 아이템 거래가 범죄 증가와 실증적인 관계가 존재하는가를 검증하였다. 분석결과, 온라인 게임 및 아이템 거래는 사이버 범죄, 재산 범죄 증가와 통계적으로 유의미한 관계가 있는 것으로 확인되었다. 그러나 온라인 게임 및 아이템 거래는 범죄 행위를 절대적으로 증가시키는 것은 아니며, 기존 범죄에 대한 새로운 대체 수단으로 활용되고 있음이 밝혀졌다. 즉 온라인 게임 및 아이템 거래는 기존의 비재산 범죄를 재산 범죄로 대체하는 역할을 하는 것으로서 추정된다. Online game industry and item trade have grown up fast after 2000. And there has been a perspective that online game and item trade are the cause of the crimes, especially cyber crime like hacking, virus. But there was no positive research about the opinion, so this article studies the relations among online game, item trade and crime. The results suggest that online game and item trade maybe a cause of cyber crime and property crime. But online game and item trade don't increase the total number of crime. That means that online game and item trade substitute the way how crime happens. Online game and item trade substitute no-property crime to property crime.

These days, there are many local festivals led by local governments. One of the main purposes of local festivals is to encourage the development of local economy. In order to achieve this goal, it is important to increase visitors` scale of spending. However, existing previous studies do not suggest specific guidelines to increase the scale of spending. Therefore, in this study, authors suggest specific implication on which part local governments should put more focus on in order to increase visitors` scale of spending. The analysis on the relations between the scale of spending and the level of satisfaction on local festival shows that the spending on shopping increases as the satisfaction level goes up. Furthermore, the increase in spending on shopping indirectly affects the increase in overall scale of spending. There are various factors such as infrastructure, public relations, diversity and culture which lead to the success of local festival. However, when it comes to the development of local economy, the most important factor is to come up with unique products of food.

LDAP는 TCP/IP상에서 X.500 디렉토리 서비스의 사용을 가능하게 하는 프로토콜이다. X.500 디렉토리에 접근할 때 사용하는 기존의 OSI 프로토콜인 DAP(Directory Access Protocol)는, OSI 상위 계층의 구조를 사용하기 때문에 구현하는데 있어 방대한 양의 프로그램 작업이 필요하다. 따라서 소규모의 워크스테이션이나 PC의 응용프로그램에서 OSI 디렉토리 서비스를 이용하기 위해서는, 응용프로그램으로 부터 DAP의 기능을 분리시키는 spilt-DUA모델을 사용해야 한다. 즉, DAP는 고성능의 워크스테이션이나 메인 프레임에 위치한 LDAP(Lightweight Directory Access Protocol) 서버에 구현하고, 응용프로그램은 LDAP서버를 통해 원하는 디렉토리에 접근하도록 해야한다. 본 논문에서는 Retix사의 X.500구현 제품인 DS-520과 미시간 대학에서 구현한 LDAP API 3.0 라이브러리를 이용한 LDAP 서버와 Unix, Windows용 클라이언트를 각각 구현하였다.

Cell culture observation and cell-based assay using a cell incubator are one of the important factors in the development of new drugs. However, most commercial cell incubators are large in size and are expensive to transport, install and maintain. In this paper, we propose a small cell incubator system that controls temperature and humidity, which is the most important factor in cell culture, and developed its controller. In order to confirm the condition of cell culture, a temperature and humidity control program was prepared and the device was driven and the results were confirmed. Experimental results show that there is almost no difference from large-scale cell incubator. It is expected that the proposed small cell incubator system will be available in the field of new drug development and drug evaluation in the future.

호흡도 기법을 통한 폐수내 COD 분율 예측

신응배,김철,김연권,박주형,김미경 漢陽大學校 環境科學硏究所 2001 環境科學論文集 Vol.22 No.-

생물학적 하·폐수 처리 공정에서의 폐수내 유기성 화합물은 미생물의 탄소원 및 에너지원으로서 중요한 의미를 가지고 있다. 그러나, 유입수내 유기물은 매우 다양하며 각 유기물 특성에 따라 미생물에 의한 분해율이 다르기 때문에, 최적 효율을 유지하기 위한 공정내 적정 유기물 부하 유지는 매우 어려운 일이다. 따라서, 유입수내 유기물의 특성과 분율을 적절하게 예측할 수 있다면, 각 유기물에 대한 미생물 분해율을 토대로 해당공정 전반에 걸친 폐수처리효율을 예측할 수 있게 될 것이며, 최종적으로 공정 효율 증대의 효과를 거둘 수 있을 것이다. 본 논문에서는 회분식 실험을 통해, 호기 조건에서 종속영양미생물에 의한 COD 소모에 따라 발생하는 산소섭취율(OUR)을 이용하여 미생물의 활성도 파악과 함께 모델에 적용하였다. 모델 적용으로 구하여진 COD 분율과 인위적으로 조성된 혼합폐수의 분율에서 유사한 결과를 나타냄으로써, 폐수내 COD 분율 예측에 있어 호흡도 기법의 적용이 매우 신뢰성 있는 측정기법으로 활용할 수 있을 것으로 판단되었다. In biological wastewater treatment process, wastewater characteristics, especially organic carbon source, was a very important parameter. But the biodegradation pattern for each organic is diverse, since wastewater contains a wide variety of different organics. So, the proper estimation of each organic fraction in wastewaters can enable estimation of the process efficiency easier. In this study, the COD fraction was determined by respirometric analysis. In order to estimate the activity of heterotrophs, readily biodegradable COD and slowly biodegradable COD were mixed in a synthetic wastewater, and microorganisms was measured by a simple batch test. The result showed that COD fractions calculated by models were similar to the composition of synthetic wastewater. This implied the applicability of the respirometric method to the estimation of COD fractions in various wastewaters.
