일반 국민, 법률전문가 등이 재판 관련 자료를 열람·대출할 수 있도록 하여 사법격차를 줄이고 사법접근성을 높이는데 일조할 수 있는 것은 사법부 국립도서관인 법원도서관 법마루가 유일하다. 이에 본 연구는 설문조사와 면담을 통해 법원도서관 법마루 서비스에 대한 이용자 만족도를 파악하고 서비스 개선방안을 도출하였다. 이용자 만족도는 5점 만점에 직원응대 4.62점, 시설관리 4.48점, 행사 및 강좌 등 문화프로그램 4.33점 등의 순이었으며, 장서구성 만족도가 3.97점으로 가장 낮았다. 이는 법 전문성이 만족도에 영향을 가장 크게 주는 부분이 장서구성이기 때문으로 보인다. 장서구성에 대한 만족도가 가장 낮았던 만큼 앞으로 법마루가 강화해야 할 서비스 역시 장서확충이 44%(114명)로 가장 높았으며, 향후 이용자층에 따른 균형 있는 장서 수집이 필요한 것으로 나타났다. 개선방안으로는 일반 국민과 법률전문가의 법원도서관 법마루 열람 공간 및 서비스 이원화, 법률 전문도서관으로서의 정체성 강화, 시스템 개선, 홍보 및 직원응대 강화 등을 제시하였다. 지속적인 문헌정보학계의 연구를 통해 법원도서관 법마루 서비스가 성공적으로 정착된다면 법학전문도서관을 비롯한 법학도서관계 전반의 서비스 품질을 향상시키고 이용자 만족도를 증대시킬 수 있을 것이다.

생태면적률은 친환경적 공간 개발을 위한 정량적 사전 계획지표이자 건축물과 외부공간의 균형 있는 개발을 유도하는 통합적 지표이다. 그러나 제도 적용상 면적 산정의 오류, 하부 지반과 토심 확보 기준의 미달, 시공 후 실제 생태면적의 감소, 사전 계획지표로서의 기능 저하 등의 문제점들이 지적되어 왔다. 본 연구에서는 이를 해결하기 위해 LIM 활용을 제안하였다. 생태면적률의 가중치는 주로 하부 지반과 토심, 피복 유형에 의해 결정되므로 지형과 포장재를 중심으로 연구를 진행하였다. 모델은 정부기관 및 관련 전문단체에서 제시한 BIM 기준과 가이드라인, 지침서를 참고하여 여기에 부합되도록 모델의 작성 범위와 상세 수준을 의미하는 LOD(Level Of Detail)를 설정하고, BIM 저작도구를 선정하여 조경정보모델을 구축하는 방법을 제시하였다. 사례 대상지로는 경사지에 위치한 공동주택단지를 선정하여 3차원적 지형을 모델링하고, 생태면적률과 관련된 속성정보를 포함한 포장재 라이브러리를 제작하였으며, 이들을 토대로 부지의 조경 정보모델을 완성하였다. 그리고 구축된 모델을 활용하여 생태면적률을 산정하고, 계획도와 산정표, 포장 상세도 등 관련 도면을 출력하였다. LIM을 활용함으로써 생태면적률의 기준 적용과 면적 산정이 정확해지고 설계업무의 효율성을 도모할 수 있었으며, 지형과 지하구조물의 관계 등 입체적 형태에 대한 객관적 검토가 가능해짐을 알 수 있었다. LIM 도입을 위해 라이브러리 매뉴얼 또는 템플릿을 작성, 배포하거나 KBIMS 기준에 부합하는 라이브러리 구축에 힘써야 하며, 인증제도에서 BIM 모델을 제출하도록 하는 제도적 전환이 필요하다. 앞으로 생태면적률에 식재 유형별 기준이 도입되어 확대 적용될 것으로 예상되므로 식재 정보 모델 구축과 활용에 대한 후속 연구가 요구된다.

현재 전 세계적으로 원자력 발전소가 직면하고 있는 문제 중 가장 큰 문제는 방사성 핵종($^{134}Cs$, $^{135}Cs$, $^{137}Cs$)에 오염된 핵 폐기물 저장 및 처리시설 확충이다. 원자력 발전소의 꾸준한 증가율에 비하여 방사성 폐기물을 처리할 수 있는 처리시설의 공간적 한계에 직면하고 있기 때문이다. 이에 환경 친화적이면서 효율적인 폐기물 처리방법의 개발이 시급하다. 이에 따라, 경제적이면서 높은 회수율을 가지는 균주와 세슘 이온의 상호 작용을 통한 방사성 세슘 생물학적 흡착에 대한 연구가 각광받고 있다. 하지만, 현재 세슘 저항성을 지닌 균주는 많이 보고되어 있지 않은 상태이다. 본 연구는 한국원자력연구원 첨단방사선 연구소 주변에서 샘플을 채취하여 세슘 저항성을 지닌 균주를 선별하였다. 세슘 저항성 균주 선별 방법은 다음과 같다. 샘플 및 100 mM CsCl을 R2A 액체 배지에 첨가한 뒤, 72시간 후에 살아남은 균주들을 16S rRNA 염기서열을 NCBI's BlastN의 database의 균주들의 염기서열과 비교/분석을 하여 균주를 동정 분석하였다. 동정 분석 결과, B. anthracis Roh-1, B. cereus Roh-2 균주들이 세슘 저항성 우점종 균주인 것을 확인할 수 있었다. B. cereus Roh-2 균주가 B. anthracis Roh-1 균주보다 세슘에 대한 저항성을 보이는 것을 본 실험을 통해 확인할 수 있었으며, 특히 50 mM CsCl 환경에서 B. cereus Roh-2 균주는 B. anthracis Roh-1 균주보다 최대 30% 이상 세슘에 대해 저항성을 가지는 것을 확인하였다. 또한, $0.2mg\;L^{-1}$ $Cs^+$가 함유된 R2A 배지를 24시간 동안 처리하였을 때, B. anthracis Roh-1 균주는 g당 최대 $2.01mg\;L^{-1}$의 세슘 흡착능을 유도결합플라즈마 질량분석기 분석을 통해 확인하였다. 본 세슘 저항성 균주 스크리닝 기술 및 선별된 균주들은 차후에 방사성 오염지역 생물학적 환경 정화 및 제염해체를 위한 플랫폼 기술로 활용될 수 있을 것으로 보인다.

현재 미국, 호주, 북유럽 등지의 해외 조경실무에서 BIM의 필요성에 대한 자각과 함께 전문적 연구가 수행되고 있으며, 관련 단체에서도 조직적 활동을 펼침으로써 BIM을 활용한 조경 프로젝트들이 증가하는 추세다. 그러나 아직 국내 조경분야에서는 BIM 도입이 이루어지지 않고 있으므로, 본 연구에서는 BIM을 활용한 조경 프로젝트 사례를 조사, 분석하여 BIM 도입에 따른 효과와 활용방법을 논하고자 했다. 이를 위해 세 가지 BIM 도입효과인 설계업무의 효율성 향상, 협업 환경의 마련, 지형설계의 형태 구현을 보여주는 조경 프로젝트들을 선정하고, 이들을 대상으로 조경정보 구축, 3D 모델링 제작, 상호운용성 확보, BIM 모델의 시각적 활용이라는 네 가지 측면에서 BIM의 활용방법을 살펴보았다. 첫째, 조경정보 구축의 측면에서 사례들을 살펴본 결과, 시설물과 수목 등 상세한 조경요소들로부터 기반시설 등 광범위한 건설정보들이 3D 라이브러리나 2D CAD 형식으로 구축되었다. 둘째, 3D 모델링 제작을 살펴보면 간단한 지형과 수목을 포함한 조경공간을 Revit으로 모델링하거나, 정교하고 복잡한 지형을 Maya와 같은 전문적 3D 모델링 도구로 모델링했다. 그리고 통합모델은 분야별 모델을 제작하여 주기적으로 교환, 검토하고, 최종적으로 이들을 통합하는 방식으로 제작되었다. 셋째, 분야간 데이터의 상호운용성은 파일 포맷의 단일화, 상이한 포맷의 변환, 또는 정보 표준의 준수를 통해 이루어졌고, 이를 토대로 건설정보를 공유하여 협업을 도모했다. 넷째, 3D 모델을 시각화함으로써 참여자들간의 의견조율, 설계안의 인허가, 대중 홍보가 이루어졌다. 사례분석을 통해 BIM은 디자인 도구라기보다 설계업무의 효율성을 높이고, 분야간 협업을 도모하는 프로세스임을 알 수 있었고, 특히 조경가들이 BIM을 활용한 통합 프로젝트에서 중요한 역할을 수행하고 있음을 확인했다. 따라서 그간 건설분야에서 BIM으로의 전환을 통해 많은 이익과 기회를 누렸듯이 조경분야에서도 적극적으로 BIM을 도입해야 할 것이다.

Recently, numerous documents have been made available electronically. Internet search engines and digital libraries commonly return query results containing hundreds or even thousands of documents. In this situation, it is virtually impossible for users to examine complete documents to determine whether they might be useful for them. For this reason, some on-line documents are accompanied by a list of keywords specified by the authors in an effort to guide the users by facilitating the filtering process. In this way, a set of keywords is often considered a condensed version of the whole document and therefore plays an important role for document retrieval, Web page retrieval, document clustering, summarization, text mining, and so on. Since many academic journals ask the authors to provide a list of five or six keywords on the first page of an article, keywords are most familiar in the context of journal articles. However, many other types of documents could not benefit from the use of keywords, including Web pages, email messages, news reports, magazine articles, and business papers. Although the potential benefit is large, the implementation itself is the obstacle; manually assigning keywords to all documents is a daunting task, or even impractical in that it is extremely tedious and time-consuming requiring a certain level of domain knowledge. Therefore, it is highly desirable to automate the keyword generation process. There are mainly two approaches to achieving this aim: keyword assignment approach and keyword extraction approach. Both approaches use machine learning methods and require, for training purposes, a set of documents with keywords already attached. In the former approach, there is a given set of vocabulary, and the aim is to match them to the texts. In other words, the keywords assignment approach seeks to select the words from a controlled vocabulary that best describes a document. Although this approach is domain dependent and is not easy to transfer and expand, it can generate implicit keywords that do not appear in a document. On the other hand, in the latter approach, the aim is to extract keywords with respect to their relevance in the text without prior vocabulary. In this approach, automatic keyword generation is treated as a classification task, and keywords are commonly extracted based on supervised learning techniques. Thus, keyword extraction algorithms classify candidate keywords in a document into positive or negative examples. Several systems such as Extractor and Kea were developed using keyword extraction approach. Most indicative words in a document are selected as keywords for that document and as a result, keywords extraction is limited to terms that appear in the document. Therefore, keywords extraction cannot generate implicit keywords that are not included in a document. According to the experiment results of Turney, about 64% to 90% of keywords assigned by the authors can be found in the full text of an article. Inversely, it also means that 10% to 36% of the keywords assigned by the authors do not appear in the article, which cannot be generated through keyword extraction algorithms. Our preliminary experiment result also shows that 37% of keywords assigned by the authors are not included in the full text. This is the reason why we have decided to adopt the keyword assignment approach. In this paper, we propose a new approach for automatic keyword assignment namely IVSM(Inverse Vector Space Model). The model is based on a vector space model. which is a conventional information retrieval model that represents documents and queries by vectors in a multidimensional space. IVSM generates an appropriate keyword set for a specific document by measuring the distance between the document and the keyword sets. The keyword assignment process of IVSM is as follows: (1) calculating the vector length of each keyword set based on each keyword weight; (2) preprocessing and parsing a target document that does not have keywords; (3) calculating the vector length of the target document based on the term frequency; (4) measuring the cosine similarity between each keyword set and the target document; and (5) generating keywords that have high similarity scores. Two keyword generation systems were implemented applying IVSM: IVSM system for Web-based community service and stand-alone IVSM system. Firstly, the IVSM system is implemented in a community service for sharing knowledge and opinions on current trends such as fashion, movies, social problems, and health information. The stand-alone IVSM system is dedicated to generating keywords for academic papers, and, indeed, it has been tested through a number of academic papers including those published by the Korean Association of Shipping and Logistics, the Korea Research Academy of Distribution Information, the Korea Logistics Society, the Korea Logistics Research Association, and the Korea Port Economic Association. We measured the performance of IVSM by the number of matches between the IVSM-generated keywords and the author-assigned keywords. According to our experiment, the precisions of IVSM applied to Web-based community service and academic journals were 0.75 and 0.71, respectively. The performance of both systems is much better than that of baseline systems that generate keywords based on simple probability. Also, IVSM shows comparable performance to Extractor that is a representative system of keyword extraction approach developed by Turney. As electronic documents increase, we expect that IVSM proposed in this paper can be applied to many electronic documents in Web-based community and digital library.

Various theories and techniques for the subject catalog have been developed since Charles Ammi Cutter first tried to formulate rules for the construction of subject headings in 1876. However, they do not seem to be appropriate to Korean language because the syntax and semantics of Korean language are different from those of English and other European languages. This study therefore attempts to develop a new Korean subject indexing system, namely Korean String Indexing System(KOSIS), in order to increase the use of subject catalogs. For this purpose, advantages and disadvantages between the classed subject catalog nd the alphabetical subject catalog, which are typical subject ca-alogs in libraries, are investigated, and most of remarkable subject indexing systems, in particular the PRECIS developed by the British National Bibliography, are reviewed and analysed. KOSIS is a string indexing based on purely the syntax and semantics of Korean language, even though considerable principles of PRECIS are applied to it. The outlines of KOSIS are as follows: 1) KOSIS is based on the fundamentals of natural language and an ingenious conjunction of human indexing skills and computer capabilities. 2) KOSIS is. 3 string indexing based on the 'principle of context-dependency.' A string of terms organized accoding to his principle shows remarkable affinity with certain patterns of words in ordinary discourse. From that point onward, natural language rather than classificatory terms become the basic model for indexing schemes. 3) KOSIS uses 24 role operators. One or more operators should be allocated to the index string, which is organized manually by the indexer's intellectual work, in order to establish the most explicit syntactic relationship of index terms. 4) Traditionally, a single -line entry format is used in which a subject heading or index entry is presented as a single sequence of words, consisting of the entry terms, plus, in some cases, an extra qualifying term or phrase. But KOSIS employs a two-line entry format which contains three basic positions for the production of index entries. The 'lead' serves as the user's access point, the 'display' contains those terms which are themselves context dependent on the lead, 'qualifier' sets the lead term into its wider context. 5) Each of the KOSIS entries is co-extensive with the initial subject statement prepared by the indexer, since it displays all the subject specificities. Compound terms are always presented in their natural language order. Inverted headings are not produced in KOSIS. Consequently, the precision ratio of information retrieval can be increased. 6) KOSIS uses 5 relational codes for the system of references among semantically related terms. Semantically related terms are handled by a different set of routines, leading to the production of 'See' and 'See also' references. 7) KOSIS was riginally developed for a classified catalog system which requires a subject index, that is an index -which 'trans-lates' subject index, that is, an index which 'translates' subjects expressed in natural language into the appropriate classification numbers. However, KOSIS can also be us d for a dictionary catalog system. Accordingly, KOSIS strings can be manipulated to produce either appropriate subject indexes for a classified catalog system, or acceptable subject headings for a dictionary catalog system. 8) KOSIS is able to maintain a constistency of index entries and cross references by means of a routine identification of the established index strings and reference system. For this purpose, an individual Subject Indicator Number and Reference Indicator Number is allocated to each new index strings and new index terms, respectively. can produce all the index entries, cross references, and authority cards by means of either manual or mechanical methods. Thus, detailed algorithms for the machine-production of various outputs are provided for the institutions which can use computer facilities.

1984년에 발행된 本誌 第6輯에 필자는 당시의 한국초록서비스의 技術現況에 대하여 조사한 결과를 발표한 바 있다. 그로부터 10년이 지난 금년에 필자는 다시 類似한 範圍와 內容의 조사를 행하여 한국초록서비스의 變化 또는 발전의 實相을 밝혀 보려고 한다. 금년 조사의 실제적 意圖는 초록서비스의 주요 道具인 이 나라 초록지의 발전과정을 10년이라는 비교적 긴 기간에 걸쳐서 觀察하고 그 持續的 특성이 어떤 것인지를 定義하려는 데 있다. 한 나라 초록지의 일반적 특성을 어느 해에 實行한 한번의 조사결과에 기초하여 定義하기는 어렵다. 韓國抄錄서비스의 기술현황을 조사한 결과 부분은 금년 여름 "한국문헌정보학회지" 발표하였으므로(최성진, 1994) 여기서는 지난 10년 동안에 관찰된 한국초록지의 일반적 특성에 대해서만 制限的으로 살펴보려고 한다. 그러나 本稿의 論議가 대부분 위의 記事와 같은 資料에 根據한 것이므로 그것을 참고하면 이해에 도움이 될 것이다. 硏究開發投資가 해마다 증가하여 최근 한국에는 많은 연구보고문헌 이 생산 축적되고 있지만 그것을 각분야 연구자와 기술자들에게 신속히 알려서 효과적으로 이용하게 해야 할 초록지는 그 種數도 적고 내용 또한 贊弱한 형편이다. 한국초록지의 내용을 충실히 하고 이용자 들에게 硏究速報媒體로서 더 유용하게 하려면 먼저 그 일반적 특성이 어떤 것이며 長點과 短點은 어떤 것인지를 定義할 필요가 있다. 本稿는 그러한 定義를 試圖하려는 것이다. 情報奉仕는 그것을 출현시킨 국가의 전통과 관습에 따라 조금씩 다른 모양으로 발전한다. 결과적으로 각국의 정보봉사나 그 도구인 초록지의 형태에도 多少間에 差異가 나타난다. 本稿는 그러한 觀點에서 世界의 普遍的 抄錄誌 形態에서 벗어나는 韓國抄錄誌의 特性을 밝히는 데 論議를 集中시키려고 한다.

The purpose of this study is twofold: to investigate into general characteristics of the abstracting services in Korea and to discuss general directions of development of the abstracting services in the country. This study is designed to achieve the purpose by gathering and analysing data related to the abstracting journals published in the past ten years and by comparing the results with similar data gathered by the investigator in 1984. The major conclusions made in this study is summarised as follows. (1) Researchers and professionals working in limited numbers of subject fields are benefited by abstracting services of recent achievements in research and development in Korea. Those in most of the fields have essentially no abstracting services of such achievements. Even many researchers and professionals in the limited numbers of the fields that have some elementary abstracting services are not informed of research results in their fields because the abstracting journals are scattered in many narrow subjects and in many cases, the abstracting journals only cover publications in some specific forms and kinds. (2) Abstracting journals of general subjects, which are supposed to be of more or less help to the researchers in the subject fields that have no abstracting journals of their own, have rapidly increased in number in the past ten years. Most of such abstracting journals carry thesis and dissertation abstracts, and the rest those of research papers published in specific places, in specific forms, by specific institutes, and of reports of research projects sponsored by specific foundations. These abstracting journals are not of the kind that comprehensively provide general readers with current awareness of publications of research results in Korea. (3) Most of the abstracting journals existing in Korea are published by institutions of higher education and research institutes, and the rest by commercial publishers, industrial firms, libraries, information centers, government agencies, research foundations, learned societies, etc. Those which publish many titles are small in number and those publish one or two titles are large in number. The former is largely made up of institutions of higher education and research institutes. (4) Ten years ago, there was not a single publishing house that produced abstracting journals. Three commercial publishing houses now produce abstracting journals. As this change occurs, centers of excellence are founded and competitive elements are introduced in abstracting services. This change, in turn, is expected to improve quality of the other abstracting journals in Korea. (5) The abstracting journals published in Korea are classified by type into those of dissertations, research papers, journal articles, patent specifications in that descending order. The fact that Master's and doctoral dissertation abstracts are dominating in Korea is due to the irrational practice of publishing those abstracts at many institutions. (6) Most of the abstracting journals existing in Korea are published by national or government-supported research institutes in order to publicise their own research outputs. Their coverage of literature is normally narrow, and naturally their value to users is limited. (7) The abstracting journals published in Korea increased in number at the rate of $77.8-100\%$ every five years in the past twenty-five years. Most of the abstracting journals that ceased to be published during the period survived for two years. (8) Korean is the desirable language for the abstracting journals designed to be distributed within Korea. About half of the abstracting journals published in Korea is printed in Korean and the other half in foreign languages, and in Korean with foreign languages. All the abstracting journals in foreign languages are printed in English xcept one, which is printed in Japanese. (9) Some twenty percent of the abstracting journals in Korea is published monthly, bimonthly, and quarterly. Others are published annually, biannually, and irregularly. The latter may not function properly as a current-awareness tool due to long intervals between their issues. It is particularly undesirable that about half of the abstracting journals in Korea is published irregularly. Most of the abstracting journals published in Korea are distributed freely to individuals and institutions selected by the publishers. (10) The abstracting journals published by the use of computers increased drastically in the past ten years. The abstracting journals produced by the conventional type-setting method will probably disappear In Korea in another ten years to come. Automation of the production of abstracting journals does not simply mean technical, economic improvement of publishing processes but availability of machine-readable databases that can be used for other purposes, including the generation of other publications and the provision of machine literature searching capabilities. Necessary steps should be taken for this important development that is occurring in the abstracting services in Korea.

The first and the second "Discussion Contest of Scientific Investigation" was evaluated in this study. This contest was a part of 'Korean Youth Science Festival' held in 1993 and 1994. The evaluation was based on the data collected from the middle school students of final teams, their teachers, a large number of middle school students and college students who were audience of the final competition. Questionnaires, interviews, reports of final teams, and video tape of final competition were used to collect data. The study focussed on three research questions. The first was about the preparation and the research process of students of final teams. The second was about the format and the proceeding of the Contest. The third was whether participating the Contest was useful experience for the students and the teachers of the final teams. The first area, the preparation and the research process of students, were investigated in three aspects. One was the level of cooperation, participation, support and the role of teachers. The second was the information search and experiment, and the third was the report writing. The students of the final teams from both years, had positive opinion about the cooperation, students' active involvement, and support from family and school. Students considered their teachers to be a guide or a counsellor, showing their level of active participation. On the other hand, the interview of 1993 participants showed that there were times that teachers took strong leading role. Therefore one can conclude that students took active roles most of the time while the room for improvement still exists. To search the information they need during the period of the preparation, student visited various places such as libraries, bookstores, universities, and research institutes. Their search was not limited to reading the books, although the books were primary source of information. Students also learned how to organize the information they found and considered leaning of organizing skill useful and fun. Variety of experiments was an important part of preparation and students had positive opinion about it. Understanding related theory was considered most difficult and important, while designing and building proper equipments was considered difficult but not important. This reflects the students' school experience where the equipments were all set in advance and students were asked to confirm the theories presented in the previous class hours. About the reports recording the research process, students recognize the importance and the necessity of the report but had difficulty in writing it. Their reports showed tendency to list everything they did without clear connection to the problem to be solved. Most of the reports did not record the references and some of them confused report writing with story telling. Therefore most of them need training in writing the reports. It is also desirable to describe the process of student learning when theory or mathematics that are beyond the level of middle school curriculum were used because it is part of their investigation. The second area of evaluation was about the format and the proceeding of the Contest, the problems given to students, and the process of student discussion. The format of the Contests, which consisted of four parts, presentation, refutation, debate and review, received good evaluation from students because it made students think more and gave more difficult time but was meaningful and helped to remember longer time according to students. On the other hand, students said the time given to each part of the contest was too short. The problems given to students were short and open ended to stimulate students' imagination and to offer various possible routes to the solution. This type of problem was very unfamiliar and gave a lot of difficulty to students. Student had positive opinion about the research process they experienced but did not recognize the fact that such a process was possible because of the oneness of the task. The level of the problems was rated as too difficult by teachers and college students but as appropriate by the middle school students in audience and participating students. This suggests that it is possible for student to convert the problems to be challengeable and intellectually satisfactory appropriate for their level of understanding even when the problems were difficult for middle school students. During the process of student discussion, a few problems were observed. Some problems were related to the technics of the discussion, such as inappropriate behavior for the role he/she was taking, mismatching answers to the questions. Some problems were related to thinking. For example, students thinking was off balanced toward deductive reasoning, and reasoning based on experimental data was weak. The last area of evaluation was the effect of the Contest. It was measured through the change of the attitude toward science and science classes, and willingness to attend the next Contest. According to the result of the questionnaire, no meaningful change in attitude was observed. However, through the interview several students were observed to have significant positive change in attitude while no student with negative change was observed. Most of the students participated in Contest said they would participate again or recommend their friend to participate. Most of the teachers agreed that the Contest should continue and they would recommend their colleagues or students to participate. As described above, the "Discussion Contest of Scientific Investigation", which was developed and tried as a new science contest, had positive response from participating students and teachers, and the audience. Two among the list of results especially demonstrated that the goal of the Contest, "active and cooperative science learning experience", was reached. One is the fact that students recognized the experience of cooperation, discussion, information search, variety of experiments to be fun and valuable. The other is the fact that the students recognized the format of the contest consisting of presentation, refutation, discussion and review, required more thinking and was challenging, but was more meaningful. Despite a few problems such as, unfamiliarity with the technics of discussion, weakness in inductive and/or experiment based reasoning, and difficulty in report writing, The Contest demonstrated the possibility of new science learning environment and science contest by offering the chance to challenge open tasks by utilizing student science knowledge and ability to inquire and to discuss rationally and critically with other students.
