빠르게 변화하는 국제경제의 질서에 副應하여 生産性을 높이고 高費用 低效率의 問題를 해결해 國際競爭力을 向上시키는 것이 오늘날의 難題이다. 이러한 環境 속에서 국내 건설산업분야도 그 해결책의 一環으로 效果的인 건설산업의 發展을 위해 건설사업관리(CM)제도의 必要性을 認識하게 되었고, 정부가 CM에 대한 法令을 制定해 CM制度의 活性化를 위한 基盤을 마련하였다. 국내 건설사업관리제도는 지난 1996년 12월 건설산업기본법에 의해 건설사업관리(CM)의 法的 根據가 마련되었으며, 건설산업기본법, 국가를당사자로하는계약에관한법률, 건설기술관리법 등에 CM 業務를 집행할 수 있는 法的 根據를 確立하고 CM制度의 定着과 活性化를 위한 여러 가지 대책을 硏究하고 檢討하였다. 그러나, 導入이후 10여년의 시간이 지났지만 국내에 導入된 건설사업관리제도는 旣存의 경직된 국내 건설산업의 構造 속에서 CM制度의 未成熟과 CM관련 制度의 infra 構築의 未洽 등으로 여전히 活性化 되지 못하고 있다. 이에 本 硏究에서는 體系的이고 科學的인 관리기법을 통해 總體的인 生産性과 效率성의 向上을 目的으로 하는 건설사업관리제도의 理論的考察을 통해 건설사업관리제도의 역사적意義와 槪念의 定義 및 有形, 그리고 機能과 役割 등을 살펴본다. 또한 국내외의 건설사업관리제도의 現況과 실제 適用事例들의 分析을 통하여 외국의 경우와 比較를 해보고 건설사업관리제도의 국내 導入과 그에따른 主要成果 및 運營상의 問題點을 살펴보아, 궁극적으로 국내 건설사업관리제도의 合理的인 定着 方案을 提示하고자 하였다. 국내 건설산업의 合理的인 CM 活性化 方案을 통해 국내 건설사업관리제도의 安定的인 定着과 發展을 유도하여 CM活動이 국내 건설산업 全般의 效率성을 제고하는 基盤이 되고, 나아가 21세기 국내 건설산업이 高附加價値를 生産하고 매력적인 산업으로 成長하여, 우리나라 건설산업의 國際競爭力을 强化시키는데 本 硏究의 意義가 있다 하겠다. A key challenge today is to increase international competitiveness by increasing productivity and by solving the problem of high cost and low efficiency in line with the rapidly changing order of international economy. Amidst this environment, domestic construction industry recognized the need for Construction Management (CM) system for the advancement of the effective construction industry as a solution measure. The government laid down the foundation for the vitalization of the CM system by enacting laws and regulations pertaining to CM. As for domestic Construction Management system, legal basis for Construction Management (CM) was developed on December 1996 due to the Base Construction Industry Law. Legal basis for executing CM tasks such as Base Construction Industry Law, law pertaining to contract whereby the nation is a party to the contract, Construction Technology Management Law and so forth were established, and various measures for the establishment and vitalization of CM system were subjected to research and review. However, although ten years lapsed by after the adoption, the Construction Management system adopted into the domestic market is yet to be vitalized amidst existing overly rigid domestic construction industry structure due to the immaturity of the CM system and lack of CM related system infra development. To this, this research examines historical significance of Construction Management system, definition and type of concept, and its functions and roles through close theoretical examination of Construction Management system that intends to improve overall productivity and efficiency through structured and scientific management techniques. Moreover, comparison with foreign cases is conducted through examination of domestic and overseas Construction Management systems'' current situation and analysis of actual application cases to examine the introduction of the Construction Management system into the domestic market, and to study ensuing importance and operation level problems with the end of recommending rational settlement measures for the domestic Construction Management system. Stable establishment and advancement of the domestic Construction Management system is induced through rational CM vitalization measures for domestic construction industry so that CM activity can serve as the basis of increasing efficiency in the overall domestic construction industry. Going steps further, significance of this research lies in increasing international competitiveness of the Korean construction industry by growing the domestic construction industry in the 21st Century into a high value add, productive and attractive industry.

The purpose of this study is to analysis the relationship between Teachers' Appointment in Biology and Biology Education curriculums in the Graduate School of Education. The questions of Teachers' Appointment in biology are based on the biology education curriculums in the graduate school of education. Therefore the curriculums should consist of contents covering overall courses of study in secondary school, which would be fundamental for students to study in University or Graduate School. This study is about whether the questions in current Teachers' Appointment correspond well to requirements in the curriculums. In this study, I used three different approaches to address these questions as follow: First, I analyzed all the questions in biology Teachers' Appointment given last 5 years from 2003 to 2007. Second, I analyzed 6 biology education curriculums in the graduate schools of education which are represented each province. Third, I analyzed the relationship of the questions and curriculums and studied how to improve the teachers' appointment in the future. When the questions in biology were analyzed, the number of questions were not enough to cover all the contents suggested in the 7th Version of National Curriculum. In addition, the questions were not related to the modern environmental biology and biotechnology. In conclusion, graduate school of education must develop unique curriculum for biology major because it aims at training secondary school teachers and the curriculums should be standardized to be connected with secondary school of biology. Teachers have great responsibility which they must develop future leaders who lead our society. Therefore, it is crucial that we select right people for the position.

In recent years, the rapid change in business environment makes a lot of enterprises accelerate their restructuring for their survival and external growth in order to maximize their corporate value through the increase of the profitability and cash flow of the enterprises. Restructuring is divided into corporate expansion, through merger & acquisition, and downsizing through sell-off. There have been hot discussions over corporate downsizing, especially sell-off, which has not been studied fully enough for lack of a sample of research data in relation to the systematic trait in our country. In addition, the domestic investors, trying to cope with the change in business environment, are changing their ways of decision-making on their investment into the reasonable ones which make much of intrinsic value of an enterprise. Therefore, the studies on how the public announcement of sell-off by an enterprise has effect on the stock prices are very suggestive. Accordingly, this study attempts to find out the investors' reactions to stock trading by way of the analysis of the effects that the public announcements of listed companies in our country have on the stock market as well as the extent of the role of the public announcement as an informative source to the investors through the analysis of the effects of sell-offs according to their types and motives. This study has been carried out by means of both philological and positive method. The reactions of stock price to the announcements of sell-offs by enterprises, based on the average abnormal excess returns(AR) and the cumulative average abnormal returns(CAR), have been analysed in a positive way through the daily data of stock prices, while the expected return rate in the course of calculation of excess returns is estimated depending on the model of the stock market. The paper's database of sell-offs were obtained from the public notification of Korean Stock Exchange or the newspaper of Korea Listed Companies Association from 1991 to 2000. The results of empirical analysis of this study are as follows; First, the full sample of 106 sell-off events show that they reap significant positive excess returns of +5.27% from these transactions (-20, 0). It proves that sell-offs, on average, are firm value enhancing activities. Second, this study reveals that sell-offs can be value destroying, or value enhancing on the motive underlying sell-off. From each subsample divided by the use of sale proceeds of sell-off type, the evidence shows that core business-originated sell-offs increase stockholder wealth +1.58% CAR, and decreasing leverage originated sell-offs increase stockholder wealth with +11.39% CAR, but operating fund supply-originated sell-offs increase stockholder wealth -2.78% CAR. This study has the limit that the sample period (-300, +10) was too short to explain all the phenomena of sell-offs. From this study we can conclude that enterprises should centralize their power upon a core business to survive rather than diversify excessively in these competitive days.
