1. 회신율은 연구 주관기관이나 설문조사 내용, 표본의 성격, 응답자에게 주는 이익의 정도, 독촉 방법에 따라 많은 차이를 보이겠지만 본 사례에서 우편설문에 관한 응답양상을 살펴본 바, 회신율에 있어서는 1차 발송후 총 대상에 대하여 약 15-20% , 미응답 대상에 대한 2차 발송 후 2차 대상의 약 30%, 1, 2차 미응답 대상에 대한 3차 발송후 3차 대상의 약 20%정도의 회신율을 보여 총 회신율에 있어서는 약 54%정도를 보이었다. 이것은 사회과학 연구 조사에서의 회신율 10-25%에 비하여는 상당히 높다고 할 수 있고(김경동, 1986), 질문서 회신율이 50%면 분석의 목적 상 무난하다고 보아야 하고, 60%면 좋은 편이고, 70%가 넘으면 아주 훌륭하다는 Babbie(1973)의 의견에 비추어 볼 때 무응답 대상에 대한 비교연구가 수반되어야 정확한 판단을 내릴 수 있겠지만 본 사례에서의 회신율은 그런대로 만족할 수 있는 수준이라고 생각된다. 2. 미응답 대상에 대한 독촉 발송 시기에 있어서는 미응답 대상에 대하여 최초 발송 2주일 후 정도가 적절할 것으로 판단되며, 3차 발송까지 시행하는 것이 회신율을 높일 수 있는 방법으로 생각된다. 3차 발송 이후에도 응답이 없는 경우 또다시 독촉(4차 이상 발송)하여도 전체 회신율에는 크게 영향을 미치지 않을 것으로 예상된다. Christopher는 정부의 후원을 받는 조사 연구의 경우 회신율이 높다고 보고하였는데 이번 조사연구에서도 관련 부처로부터의 협조 공문이 회신율을 높이는데 기여하였다고 사료된다(Oppenheim, 1966).

As the Enforcement Ordinance of Environmental Policy Act was revised in 2013, total organic carbon(TOC) was added as an indicative parameter for organic matter in Water and Aquatic Ecosystem Environmental Criteria. Under these imminent circumstances, a regulatory standard is needed to achieve the proposed TOC limitation control water quality from the public sewage treatment plants(PSTWs). This study purposes to present the determination method for TOC effluent limitation at the PSTWs. Therefore we investigate the TOC effluent limitation of foreign countries such as EU, Germany and USA, and analyse the effluent water qualities of PSTWs. In using these TOC data, we review apprehensively the statistics-based, the technology-based, and the region(water quality)-based determination method of TOC effluent limitation for PSTWs.

The feasibility of stimulating in situ aerobic cometabolic activity of indigenous microorganisms was investigated in a trichloroethene(TCE)-contaminated aquifer, A series of single-well natural drift tests (SWNDT) was conducted by injecting site groundwater amended with a bromide tracer and combinations of toluene, oxygen, nitrate, ethylene and TCE into an existing monitoring well and by sampling the same well over time. Transformation of ethylene, a surrogate of overall TCE transformation activity, was also observed, and its transformation results in the production of ethylene oxide, suggesting that some tolune-oxidizing microorganisms stimulated may express a monooxygenase enzymes. Also in situ transformation of TCE was confirmed by dilution-adjusted data analysis developed in this study. These results indicate that, in this environment, toluene and oxygen additions stimulated the growth and aerobic cometabolic activity of indigenous microorganisms expressing monooxygenase enzymes and that these are responsible for observed toluene utilization and cometabolism of ethylene and TCE. The simple, low-cost field test method provides an effective method for conducting rapid field assessments and pilot testing of aerobic cometabolism of TCE, which has previously hindered application of this technology to groundwater remediation.

Anaerobic reductive dechlorination of tetrachloroethylene(PCE) to ethylene was investigated by performing laboratory experiments using semi-continuous flow two-in-series soil columns. The columns were packed with soils obtained from TCE-contaminated site in Korea. Site ground water containing lactate(as electron donor and/or carbon source) and PCE was pumped into the soil columns. During the first operation with a period of 50 days, injected mass ratio of lactate and PCE was 620:1 and incomplete reductive dechlorination of PCE to cis-DCE was observed in the columns. However, complete dechlorination of PCE to ethylene was observed when the mass ratio increased to 5,050:1 in the second operation, suggesting that the electron donor might be limited during the first operation period. During the degradation of cis-DCE to ethylene, the concentration of hydrogen was $22{\sim}29mM$. These positive results indicate that the TCE-contaminated groundwater investigated in this study could be remediated through biological anaerobic reductive dechlorination processes.

This study aims to raise academic library funds in Korea through how to raise funds and what conditions are. In order to do this, case studies on academic library funds of university in America as well as academic library funds of university in Korea have been analyzed. As for the specific plan for raising academic library funds, I have indicated to establish office for library development and include library as one of allotment for infrastructure which is similar to the Development Impact Fee in the U.S.A., and the use of library supporting organizations like "Library Friends."

This study was carried to analyze the current status of oral history collections of national libraries in foreign countries and to derive key factors to consider when building oral collections in National Library of Korea(NLK). The Library of Congress, the British Library, and the National Library of Australia regard oral records as a national heritage that should be passed down nationally and those have been utilized and preserved successfully. Based upon the analysis of the oral collections of these national libraries, several key elements - legislation, organization, collection policy, services, collection, education and collaboration, funding and sponsorship-to consider when building an oral history collection for the first time in the NLK were suggested.

Objectives: In this study, it was analyzed which marketing activity strategy multinational tobacco companies established against Republic of Korea through their internal documents and it was checked out how the marketing activities mentioned in the documents turned out to be actually. Methods: For that, analyzed the internal documents of tobacco companies after connecting Legacy Tobacco Documents Library(LTDL). Three documents were selected finally out of total searched 1,752 documents except the ones that did not include the theme or not appropriate. Results: Internal documents analysis showed that people smoke because the filter of cigarette shown in the movies looks nice. Tobacco companies carried out the marketing through sponsorship of soccer games, F1 Grand Prix was found in the internal documents. Conclusions: The legal restriction on marketing activities of tobacco companies should be enhanced by removing the articles of allowing advertisement and promotion for tobacco companies in Korean domestic law.

The campus outdoor space in each city is a very important space for students and local residents. Especially, for students, indoor space such as classroom is the main place to learn knowledge. But the outdoor space provides an opportunity to interact with people in other sectors and it also gives an opportunity that can make students sense the flow of the times. Moreover, students have the opportunity to integrate knowledge of the other fields in the outdoor space. The campus also provides an important resting place for residents. Therefore the campus should be convenient for both local residents and students, and should be designed to let students and local residents communicate with each other in outdoor space. This study attempts to identify the problems of the outdoor space in such a point. The high scores of campus evaluation indexes are as follows: First, the lighting in the favorite space and installing seats in a green space of the vestibule get the highest score. Also, separation of a sidewalk and a roadway, the ease of holding events, simple food and beverage near the entrance, the interacting place of people, the resting place near the porch in cold winter, the lighting in a bus stop and parking lot also get good evaluations.
