황명석,조창희,박종희,Whang, Myung-Suk,Cho, Chang-Hee,Park, Jong-Hee 한국생약학회 2000 생약학회지 Vol.31 No.2

'Ha Go Cho (夏枯草)' is one of the Chinese crude drugs used mainly as a diuretic. With regard to the botanical origin of 'Ha Go Cho', it was reported by Su et al. that those from China were originated from the fruited spica of Prunella vulgaris L. of Labiatae. It was, however, for the herba or spica of Prunella vulgaris L. var. lilacina Nakai from Korea. According to survey of markets in Korea, most of the materials collected in the markets seemed to be originated from Prunella plant, while some seemed to be Thesium plant of Santalaceae. To clarify the botanical origin of 'Ha Go Cho', the anatomical characteristics of Prunella vulgaris L. var. lilacina Nakai and Thesium chinense Turcz. were studied. As a result, it was clarified that some 'Ha Go Cho' from Korea were the herba or spica of Prunella vulgaris var. lilacina, whereas some others were the herba of Thesium chinense.

주변정보 분할을 이용한 주제 중심 웹 문서 수집기

주제 중심 웹 문서 수집기는 검색엔진에서 최신의 웹 문서 색인을 유지하는 대안방안으로 부상하고 있다. 그러나 주제 중심 웹 문서 수집기는 비 관심문서에서 연결된 관심문서들을 수집할 수 없는 문제점을 가지고 있다. 이러한 문제점은 문서의 구조적 특징을 고려하지 않아서 발생한다. 특히 문서분석 방법인 문서의 발생 횟수 및 역문헌 발생빈도는 이러한 문제를 야기하는 주요 원인이 된다 주제 중심 웹 문서 수집기의 성능을 향상하기 위해서 본 논문에서는 국소 정보기반의 문서 분할법을 제안한다. 본 논문에서는 문서를 하이퍼링크 주변의 문맥을 고려한 특징 정보들을 사용하여 여러 소각의 문서로 나눈다. 본 논문에서 제안하는 주제 중심 웹 문서 수집기는 나누어진 문서들을 이용하여 하이퍼링크가 관심문서를 가리키는 것인지를 판단하여 문서를 수집할 것인지를 판단한다. The focused crawler is a topic-driven document-collecting crawler that was suggested as a promising alternative of maintaining up-to-date web document Indices in search engines. A major problem inherent in previous focused crawlers is the liability of missing highly relevant documents that are linked from off-topic documents. This problem mainly originated from the lack of consideration of structural information in a document. Traditional weighting method such as TFIDF employed in document classification can lead to this problem. In order to improve the performance of focused crawlers, this paper proposes a scheme of locality-based document segmentation to determine the relevance of a document to a specific topic. We segment a document into a set of sub-documents using contextual features around the hyperlinks. This information is used to determine whether the crawler would fetch the documents that are linked from hyperlinks in an off-topic document.

Nowadays, the number of school students in rural area has decreased significantly. For this reason, there are mixed classes among students of different grades in schools in rural area. Moreover, there are several teachers who teach two and more subjects except for the major of teacher so educational environment has been deteriorated. To tackle this problem, the ministry of education has suggested merging small schools in rural area. However, some people believe that merging small schools would make educational environment more worse and would not solve this problem. To solve this problem, this research suggests that the proper solution for educational environment of merging small schools through surveying environment of merging schools.

The user participatory design process collects users' opinions efficiently through a feedback process such as various user workshops and conferences. When users who actually participated in a design process use the facility in which they were a participant, their satisfaction with the design quality of the facility they use may be enhanced; therefore, user participatory design methods in school construction are deemed to enlarge consistently the interest in a school of students, parents, teachers, and local residents. This paper selected the most appropriate user participatory design methods through an analysis of actually applied cases, and applied them to the empirical exploration process. Also, problems incurred through the empirical exploration process were solved by various user participatory design methods based on actually experienced cases and the results of workshops performed. As such, this paper deduced problems by applying user participatory design methods in practice, and solved problems by executing the empirical exploration process again. Through this, the paper proposed a variety of user participatory design methods for improving school design and raising user satisfaction.

This study reviews the influence function method(IFM) for calculating stress intensity factors (SIFs, K) and modifies it to apply for the estimating the residual fatigue life for the cracked components under complex stress fields. An IFM has been developed to analyze SIFs for surface cracks which are subjectedto nonuniformly distributed stresses. Through elastic superposition, the influence function method properly accounts for redistribution of stress as the crack grows through the component. This influence function is unique to the given geometry and independent of the loading. Some examples have been provided to show the effectiveness of the IFM including the distributions of K in a residual stress field. The significant effect of residual stress upon fatigue crack growth in a welded component has been demonstrated with the IFM.

Current, integrated schools are small schools in rural areas and old towns with declining population, or special purpose middle and high schools. And new residential districts in urban areas including Seoul have also been established in integrated schools. In particular, the number of school of central investment evaluation for integrated schools in urban areas is increasing. In this way, integrated schools, which have been mostly implemented in small rural areas, are being introduced as new ways to establish schools in urban housing development areas where the number of students is small or the number of students is difficult to predict. However, many studies of integrated school have been limited to appropriate scaling of small schools in rural areas, school management methods, and satisfaction surveys. The study of integrated school in urban areas is also focused on the study of architectural planning. In addition, there were limitations in suggesting the comprehensive establishment plan of schools or approaching urban planning when developing housing complexes. The purpose of this study is to suggest efficient establishment plan of integrated school in the development of urban housing complexes.

The recent decline in the school-age population has led to a more conservative and conservative approach to the establishment of schools. In the judgment of school establishment, it is required to make a decision method that can make objective and comprehensive judgment of various situations rather than local analysis of a single school. In this changing situation, EduFine system and placement establishment system were introduced to comprehensively analyze the feasibility of student placement and school establishment. However, the EduFine system of the Ministry of Education has few users because it is difficult to use education and it is difficult for users to use. Based on the GIS, the placement establishment system was able to analyze the number of students and the status of apartment buildings in a comprehensive manner. But placement establishment system has been used mainly in support of investment assessment rather than research. Therefore, there is a need to increase the utilization of users by linking two systems or integrating them into one system. In this study, we want to derive the functions to improve the GIS - based layout establishment system through user analysis such as comparative analysis and survey of existing systems. In particular, the purpose of the study is to improve the function of system, to improve the students' placement ability and the school establishment work ability and to improve the user satisfaction.

There is a growing demand for public kindergartens due to the problem of private kindergartens. However, when the kindergarten is built in the residential land development area, the cost of purchasing the land increases, and the overall project cost is increasing. This situation puts a lot of burden on educational finances. Therefore, to reduce the cost of establishing a kindergarten, it is required to revise related laws including act on the special cases concerning the procurement, etc. of school sites. The purpose of this study is to propose the revised laws to expand public kindergartens. In this study, the present situation of infants and kindergartens was analyzed through policy data and statistics. And the analysis of the investment evaluation data also analyzed the problems in establishing kindergarten. In addition, we conducted surveys and FGI analyzes on school sites and kindergarten related laws and regulations. Finally, this study aims to find a way to amend related acts of urban and architectural Planning for Invigoration of Public kindergarten establishment by analysis data.
