This study implicated that the CBT-AK5 purified from Lactobacillus casei (LAFTI L26) which showed antitumor activity in ICR mice. Hence, ICR mice were inoculated intraperitoneally Sarcoma-180 as well as CBT-AK5. Then we observed the life span and tumor increment of those ICR mice. Here our studies showed effect on two different way of treatment as intraperitoneally and orally treated in Sarcoma-180 infected ICR mice. We found that intraperitoneally treatment of Sarcoma-180 and CBT-AK5 is more effective than orally fed. The life span of the ICR mice were highly reduced after the inoculation of Sarcoma-180. Those effects like increment of body weight, the growth of ascites and solid were inhibited significantly after the treatment of CBT-AK5 in Sarcoma-180 infected ICR mice. Finally these studies suggested that CBT-AK5 isolated form Lactobacillus casei showed excellent antitumor activity against Sarcoma-180 infected ICR mice.

The industrial community in a metropolis has played an essential role to keep business in a large city. This paper aims to analyze the realities of trade network among enterprises at Buksungro Tools Commercial Cooperative in Daegu. The urban style industrial community is found at Buksungro in Daegu. There are more than one hundred small-sized enterprises. Major trades among enterprises are occurred within and/or by the area. The long-term trade networks within the Buksungro Tools Commercial Cooperative have played the key role to maintain the industrial community. The trade relationship has depended on business networks based on social capital rather than commercial mechanism. The trade networks have been established through credit transactions as well as handling troublesome orders. The trade networks help to transfer technology and to learn the tacit knowledge among firms. The long-term trade networks are more influenced by the social accessibility than spatial accessibility.

Modern society often faces 3Cs：change, competition, and customer. The main issue of today's police science study, therefore, circles around how public police effectively cope with the radically changed environment. As one of the workable and appealing policy tools to reform the police, the privatization has been not only strongly supported in terms of a theoretical study, but also widely used in practice all over the world. However, Policing has been widely regarded as an exclusively public-sector activity conducted by sworn officer, but a large and increasing share of the aggregate demand for public safety and security is being handled by the private sector. This study examines on the very practical one, how contracting out, most widely used as the privatization alternatives, is perceived and put into practiced in the field of traffic police services. This study is intended to examine recent shifts toward privatization of traffic policing. Although some people regard police services as inappropriate for privatization, most everyone else have persuasively considered that many police services are not public goods or, at least, not pure public goods. We can consider that there are three types of privatization with respect to traffic policing, that is, user-financed police services, contracting out, and some degree of service shedding. As society changes, so must traffic policing. And it is needed to enhance the ability of traffic police and private to accomplish their primary mission, to serve and protect the public.

The main purpose of this research is to standardize the logging operation with special reference to the net working time for thinning. This study was carried out to obtain the standard working method and working technique for Korean logging operation through the comparison of the present Korean working method and the German standard working method 1. The net working time devided into work elements showed little difference between those two working methods. 2. From the correlation analysis, net working time was significantly correlated with breast height diameter, the dependant variable, with the highest correlation coefficient in each species. 3. Total working time increases by 11 to 13 seconds to every 1 centimeter increase in breast height diameter from i to 16 centimeter. 4. The result of this study concluded that the German working method is recommended for improving the labour problems in the forest operation due to high wages and lack of manpower gradually increasing from now in Korea. In addition to the application of this standard working method, the technical training for the method should be done to the workers for improving the productivity.

Disgust is caused by human being incompleteness and also its denial. Therefore the understanding of disgust is concerned with the understanding of humans. Thinking critically about disgust, we can solve the problems of disgust and reflect on our limitations. I will refer to Nussbaum's view which finds out in "projective disgust" an antipathy to human fault and a wish for completeness. This article is interested in the fact that disgust is not only a rejective feeling of a person but also a collective emotion which is connected with an antagonistic relationship and power exercise. Specifically, this article focuses on the point that disgust is mobilized to maintain a dominative relationship between humans. This is associated with the inner characteristics of disgust because disgust in itself contains a one-sided perspective, exclusiveness, hierarchy, and domination. This article aims to reveal a collusion between disgust and domination. For the purpose we will pay attention to two basic inclinations which are immanent in disgust; purity and exclusion, while relying on Nussbaum's view of disgust. In accordance with this analysis, this article will specificity treat disgust which can be summarized as an ideological function of emotion and its violent tendency. Then, we can ensure that disgust threats the equal and dignitary worth of human beings and hinders the diversity and rationality of a liberal society. In addition, it will be emphasized that disgust should not be used as an ideology which discriminates and suppresses a specific group in a society.

Keiji Kobo is a unique self-generated design research group in Japan, which was founded in 1928 when Bauhaus movement was in its peak, and which lasted ten years until the end of the Second World War, when any activity of the group became virtually impossible due to the war. With insight to see the future, the group aimed at Modern Design advocating a new spirit in architecture, and played a significant role in prosperity of Japanese Modern Design assimilating Western design trends. Pursuing of craft works for everyday life--practical furniture works--Keiji Kobo actively executed various projects to realize modern philosophy. The range of the works of this group was very large: survey, mock-up, experiment, research, exhibition, lecture, order-based sale, advertising and writing. The works of the group were oriented to serious academicism, not compromising with commercialism. Considering the peculiar political situation such as Japanese Militarism, the spirit of functionalism that the group pursued was surprisingly academical and pure. This group was relatively small and clumsy, which lasted as short as around ten years. However, strong motivation was in their seemingly quiet movements, and the influence of the group cannot be underestimated even with today's criteria. There were a number of pioneers who contributed to today's prosperity of Japan and Keiji Kobo can be estimated to be one of the pioneers in the field of design. It was found that the contemporary intellectuals hoped that the committment and activity of the group would contribute to modernization of the life quality of ordinary people. In a sense, Keiji Kobo can be estimated to be a little Japanese equivalent for Bauhaus that could not fully bloom.

웹의 확산과 더불어 웹 페이지 검색의 성능 즉, 빠른 응답시간과 확장성(scalability)은 각 웹 사이트의 절대적 평가 기준이 되었다. 웹 옹용은 일반적으로 불특정 다수를 대상으로 하기 때문에 확장성 또한 주요 성능의 척도가 된다. 이와 같은 웹 사이트 성능을 담보하기 위한 대표적 요소기술이 웹 캐슁이다. 본 논문은 웹 상에서 XML 데이터베이스 기반의 웹 응용(XML database-backed web application)을 위한 응용서버의 XML 캐쉬를 이용하여 주어진 XML 질의를 변환, 처리하는 기법과 구현에 관한 것으로 XPath의 경로표현식 중 가장 중요한 세 가지 기능인 조건을 명시하는 필터 연산자, 부모-자식 관계를 나타내는 경로 연산자(/), 그리고 조상-후손 관계를 나타내는 경로 연산자(//)를 연구 범위로 하였다. [2]에서는 조상-후손 관계를 나타내는 경로 연산자(//)가 없는 경우에 경로표현식으로 주어진 XML 질의를 캐쉬를 이용하여 변환, 처리하는 알고리즘을 제시하였는데 본 논문에서는 [2]의 알고리즘을 확장하여 경로 연간자(//)가 지원되도록 하였다. 조상-후손 경로 연산자(//)로는 정규경로 표현식(regular path expression)을 나타낼 수 있는데 이는 스키마가 불확실한 반구조적 데이터인 XML 데이터에 대한 질의 표현에 유용하다. 제시된 알고리즘에서는 DTD를 이용하여 경로 정보를 얻어 처리함으로써 주어진 질의를 캐쉬와 하부 XML 소스에 대한 질의로 변환하였다. 이 알고리즘을 바탕으로 관계 DBMS를 이용하여 구현된 시스템으로 실제 웹 상에서 성능 실험을 수행하였다. 성능 실험 결과 정규 경로 표현식을 포함하는 XML 질의에 대해서도 웹에서 캐쉬를 이용한 처리가 효율적임을 확인하였다.키는데 목적이 있다.RED에 비해 향상된 성능을 보여주었다.웍스 네트워크상의 다양한 디바이스들간의 네트워크 다양화와 분산화 기능을 얻을 수 있었고, 기존의 고가의 해외 솔루션인 Echelon사의 LonMaker 소프트웨어를 사용하지 않고도 국내의 순수 솔루션인 리눅스 기반의 LonWare 3.0 다중 바인딩 기능을 통해 저 비용으로 홈 네트워크 구성 관리 서버 시스템 개발에 대한 비용을 줄일 수 있다. 기대된다.e 함량이 대체로 높게 나타났다. 점미가 수가용성분에서 goucose대비 용출함량이 고르게 나타나는 경향을 보였고 흑미는 알칼리가용분에서 glucose가 상당량(0.68%) 포함되고 있음을 보여주었고 arabinose(0.68%), xylose(0.05%)도 다른 종류에 비해서 다량 함유한 것으로 나타났다. 흑미는 총식이섬유 함량이 높고 pectic substances, hemicellulose, uronic acid 함량이 높아서 콜레스테롤 저하 등의 효과가 기대되며 고섬유식품으로서 조리 특성 연구가 필요한 것으로 사료된다.리하였다. 얻어진 소견(所見)은 다음과 같았다. 1. 모년령(母年齡), 임신회수(姙娠回數), 임신기간(姙娠其間), 출산시체중등(出産時體重等)의 제요인(諸要因)은 주산기사망(周産基死亡)에 대(對)하여 통계적(統計的)으로 유의(有意)한 영향을 미치고 있어 $25{\sim}29$세(歲)의 연령군에서, 2번째 임신과 2번째의 출산에서 그리고 만삭의 임신 기간에, 출산시체중(出産時體重) $3.50{\sim}3.99kg$사이의 아이에서 그 주산기사망률(周産基死亡率)이 각각 가장 낮았다. 2. 사산(死産)과 초생아사망(初生兒死亡)을 구분(區分)하여 고려해 볼때 사산(死産)은 모성(母性)의 임신력(

In contrast with product design field, some designers who work in furniture field tend to do their own studio works as well as typical designing part. Especially in the small furniture studios for the limited quantity batch production, custom made or handmade craft furniture which is finished with high quality, the propensity for their own production is more obvious than in the big furniture companies in this case. In this kind of small-scale furniture studios, they have more chance to create the various formative works and 'curved shape' is one of the most important elements to form creative pieces. Except by caning, it is very difficult to make curved wooden shape because of own characteristic of wood. Therefore, the special techniques of bending wood are essential to formative furniture production and vacuum press system is introduced as a main subject for the bending wood method in this study. Especially for the designers who work as makers as well at the small furniture studios, the value of vacuum press system on efficiency and productivity of work was sought by testing and improving the method of wood bending techniques. According to this practical searching, ideally sufficient condition on vacuum pressing work was founded as a result on this study.

탄소섬유는 전구체의 종류에 따라 PAN계, 피치계 그리고 레이온계로 나뉘며 최종 탄소섬유의 특성에도 차이가 있는 것으로 알려져 있다. 최근에는 PAN계 탄소섬유가 세계 시장의 대부분을 차지하고 있으며, PAN계 탄소섬유의 초경량, 고강도, 고탄성, 내약품성 그리고 열안정성 등의 우수한 특성으로 최첨단 고기능성 제품의 복합재로 많이 이용되고 있다. 그러나 탄소섬유가 가지고 있는 높은 열전도성은 적용에 따라 단점으로 작용될 수도 있다. 예를 들면, 로켓 엔진의 노즐이나 원자로의 구조물 그리고 극한조건용 구조재료 등, 고강도 단열특성을 요하는 최첨단 복합재로 응용 범위를 넓히는데 한계로 작용한다. 레이온은 최초의 탄소섬유 전구체였으나 공정상 경제성이 떨어지는 이유로, 지금은 고탄성을 요구하는 특수 목적으로만 소량 생산되고 있다. 레이온의 주원료는 셀룰로오스이며 셀룰로오스는 지구상에서 가장 흔한 재료이므로 오늘날 셀룰로오스를 보강재로 이용하려는 연구가 활발히 진행되고 있다. 본 연구에서는 탄소섬유의 열전도도를 낮추기 위한 방법으로 안정화셀룰로오스를 첨가한 PAN용액을 출발물질로 탄소섬유를 제조하고 특성 연구를 진행하였다. PAN용액에 셀룰로오스의 분산성을 향상시키기 위해 셀룰로오스를 열처리하였다. 이 과정에서 얻어진 안정화 셀룰로오스의 수율을 높이기 위해 셀룰로오스를 난연 처리하였으며, 그 결과 안정화셀룰로오스의 수율을 향상시킬 수 있었다. 안정화셀룰로오스를 첨가시킨 PAN계 탄소섬유의 물리적, 기계적 그리고 열적 특성을 SEM, XRD, 만능 인장시험기, TGA 그리고 Laser Flash Method 등을 통해 주요 특성 및 변화를 관찰한 결과, 순수한 PAN계 탄소섬유의 특성과 유사한 결과를 얻었다. 향후 몇 가지 공정상의 문제점을 개선한다면 흥미로운 결과를 기대할 수 있을 것으로 본다.
