The purpose of this stud)r was to critically review the trends of research methodologies of environmental education. We analyzed Journal of Korean Society for Environmental Education (vol. 1 ∼vol. 14(1)) and The Journal of Environmental Education(vol. 25∼vol. 31) to investigate the trends of methodology in EE research of Korean and other countries and to explore the tasks of it. The findings were as follows, 1) More than half of the character of the papers in Korea were actual condition (54.38%), substitute proposal (32.12%), and the papers in others countries were actual condition (39.35%), substitute proposal (33.55%). 2) The major parts of the method of the papers in Korea were literature review (26.05%), survey research (23.79%), on the other hand the papers in other counties were survey research (42.70%), literature review (25.84%). The results indicated that the research methodologies of environmental education in Korea were needed to be reinforced in the field of qualitative and quantitative research methods.

Mutual radiation impedance becomes more important in the design and analysis of acoustic transducers for higher power, better beam pattern, and wider bandwidth at low frequency sonar systems. This review paper focused on literature survey about the researches of mutual radiation impedance in the acoustic transducer arrays over 60 years. The papers of mutual radiation impedance were summarized in terms of transducer array structures on various baffle geometries such as planar, cylindrical, spherical, conformal, spheroidal, and elliptic cylindrical arrays. Then the computation schemes of solving conventional quadruple integral in the definition of mutual radiation impedance were surveyed including spatial convolution method, which reduces the quadruple integral to a double integral for efficient computation.

This study aims to investigate the effects of learning strategy-based early reading instruction for English underachieving students. For this purpose of the study, sixteen learning strategies were driven from the review of previous related literature and the result of the survey conducted to the students and the teachers. Strategy integrated early reading instruction was implemented to nine students for thirteen weeks. The word recognition test was conducted before and after the instruction to examine whether the instruction had effects on the increase of their early reading skill. In addition, in order to investigate certain change in students' affective aspects after the instruction. The research conducted survey to the students. A teacher's field note and students' class journal were also analyzed to verify the results from the quantitative test. The results indicated that the instruction led to the increase of students' early reading skills. It was also found that the instruction motivated the underachieving students to devise a strategy for their learning process.

A literature survey has been reported of the systems analysis on the liquid rocket engines. The analysis tools are mainly about the calculation of the rocket engine performance at the early days. However recent trend shows that researchers try to develop an integrated environment of distributed analysis tools for faster and cheaper analysis. This article presents the systems analysis results of the liquid rocket engine of gas generator cycle using the published mass estimating model. The specific impulse change for various thrust to weight ratio agrees qualitatively well with the published data.

The issue of sustainability has been prevailed not only in building industry but also all other industries. It has been raised that the concept of sustainability should take into account for the design of multi-use high-rise apartments. In this study, the present situation and trends of the multi-use high-rise apartment construction have been reviewed. The definition of sustainable design of high-rise apartment has been clarified so as to perceive the related design elements through the literature survey. Finally this study has derived the sustainable design elements of high-rise apartment unit plans through the comparative analysis of sustainable design guidelines, environmentally friendly building accreditation systems and literature survey in and abroad.

본 논문은 생산성 수준과 생산성 성장에 대한 노동조합의 효과를 분석한 연구문헌에서의 이론과 실증 연구결과들을 조사 분석한 것이다. 노동조합과 생산성 수준 및 생산성 성장의 관계에 대한 이론과 연구결과들이 다양하기 때문에 노동조합이 생산성에 미치는 효과의 방향이나 크기에 대해서는 결론적으로 단언하기는 어렵고, 결국 적절한 모형과 자료를 가지고 실증분석을 해봐야 알 수 있는 문제이다.

Delay is one of the most critical issues for construction projects and leads to huge losses in both developing and industrialized countries. The construction sector in Rwanda, a rapidly-developing nation, is no exception. Delays can be mitigated only once we have identify their primary causes, and these may not be the same in each region. This study aims to ascertain the main critical factors responsible for delays in building construction in Rwanda through an intensive literature review and questionnaire survey. A total of 40 delay causative factors were obtained from a literature review and were further classified into nine major categories. The questionnaire survey was distributed to about 80 respondents from clients, contractors, and consultants. From the list of 40 different factors, the top twelve most critical causes were identified as stoppage of work due to cash flow constraints, delay in approving design documents, confidentiality of physical plan, price fluctuations and delay in approving significant change, change orders, delay in performing inspections, Ineffective project planning, inadequate drawing details, unqualified labor, lack of materials on the market and dishonesty.

Objectives: The Korean Working Conditions Survey(KWCS), which has been conducted five times over the past 13 years, presents a diverse picture of Korean workers across occupations, genders, and age groups. This study summarized the use of KWCS and explored how to make the most of the KWCS by reviewing published peer-reviewed journal articles employing the KWCS data. Methods: Articles were selected in accordance with PRISMA protocol for a systematic literature review. A total of 155 articles were included in this review. Results: The number of articles utilizing KWCS data has been increasing by year. The articles were published in 40 Korean journals and 16 international journals. The journals were mainly in the field of occupational safety and health and sociology. Keywords of mental health, working conditions survey, workforce, health, exposure to risk factor, and working time were mainly highlighted. The articles were grouped by the goals of the KWCS as stated in the survey. The majority of published articles(129 articles, 83%) aimed to 'analyze relationships between different aspects of working conditions'. Fifteen articles(10%) were intended to 'identify groups at risk and issues of concern.' The number of articles to 'monitor trends' were limited. Conclusions: The findings underline the limited utilization of the KWCS. Attention to the range and scope of utilization of KWCS should be developed to address current challenges in occupational health and safety management and policy issues.

The objective of this study is to investigate actual conditions of terrestrial vegetation part in Environmental impact statement, and to prepare a proposal for the efficiency of Environmental Impact Assessment. 13 E.I.S.s made out during 1996.6-1997.5. have been chosen and analysed with respect to scope of survey, item of survey, method of survey, and result of survey. Actual conditioins of terrestrial vegetation part in E.I.S. are summarized as follows : 1. The mean number of total participants in drawing up E.I.S. is 26.0 persons, that of participants in terrestrial vegetation part is 2.3 persons. 2. In case of planar project, the mean of scope of survey is 16.1 times as large as area of project . In case of linear project, the scope of survey has been determined arbitrarily. 3. The most part of survey has been dependent on literature, and field survey has been practically neglected. 4. Results of survey mostly missed the point that E.I.A. pursues. And proposals are as follows : 1. Participants in terrestrial vegetation part in drawing up E.I.S should be increased. 2. It is necessary to subdivide scope of survey in view of difference between planar project and linear project. 3. As for item and method of survey, field survey should be specially reinforced. 4. Several sheets of map as results of survey should be included in E.I.S. The vegetation map, the D.G.N. map, and the planting map should be included and drawn by smaller scale as possible.
