  • Objectives : Since The Journal of Korean Acupuncture and Moxibustion Society(JKAMS) started publishing in 1984, randomised controlled trials(RCTs) and non-randomised clinical studies(NRSs) consistently have increased in quality and quantity. There has been no study on quality assessment of NRSs. Thus, this study evaluted non-randomised comparative clinical trials in the JKAMS to assess the quantity and quality. Methods : Upon extracting NRSs for assessing the intervention effects from all the articles published in the JKAMS from 1984 to 2009, assessments were made on methodological index for non-randomised studies(MINORS). Also, the analysis were made upon the proportion of non-randomised comparative clinical trials within original articles. The mean scores by research methods and years, and total scores and mean scores of yearly research methods were analyzed. Results : A total of 44 trials on non-randomised comparative clinical trials were selected. In 1980s, 4.3% of the total selected original articles, in 1990s, 4.1%, and in 2000s 14.2% were NRSs. According to the research designs, the mean scores of MINORS were Case-control study 18.3, Controlled before and after 18.5, Quasi randomised trial 18.5, and non randomised trial 17.9(out of 24), respectively. Cross-sectional study was the most frequently used(41.9%). Conclusion : Although NRSs consistently increased in quantity, the assessed mean scores were low and most articles used Cross-sectional study. Thus, there should be studied using appropriate research methods in the future.

  • This paper analyzes the environmental impact and economic effect of introducing the Renewable Portfolio Standard (RPS) into the Korean electricity market using the DECADES (Database and Methodologies for Comparative Assessment of Different Energy Sources for Electricity Generation) model, a comparative assessment tool developed by IAEA. A bottom up approach is adopted for the evaluation of air pollutant emission and its impact of several RPS scenarios. The environmental damage costs of RPS scenarios are evaluated based on the Extern-E results and the Thailand externality study carried out by EGAT. The results of this study can be applied in determining or analyzing the national electricity policy and energy policy.

  • Recently, the development of sustainable building assessment tools as means to invigorate the dissemination of sustainable buildings has been actively progressed. However, many assessment tools involve various problems in terms of assessment method and system framework, which greatly impede their credibility and applicability. If these problems persist over time, the role of sustainable building assessment tools as decision making measures during the design stage will be greatly limited. The objective of the study is to suggest a systematic model for sus- tainable building assessment tools by establishing a logical system of performance assessment framework. For this purpose, the Environmen- tal Impact Assessment(EIA) framework used in selected and modified to fit the building performance assessment. The analysis of performance assessment tools for sustainable buildings was conducted using the EIA framework. Based on the results of the analysis, a framework for the performance assessment of sustainable buildings was established.

  • Fatigue strength assessment procedures have been implemented in the ship design rules by many classification societies. However, a large variation tin the details of the different approaches exists in practically all aspects influding load history assessment, stress evaluation and fatigue strength assessment. In order to assess the influences of thesd variations on the prediction of fatigue lives. a comparative study is organized by the ISSC Committee III.2 Fatigue and Fracture. A pad detail on the top of longitudinal hatch coaming of a panamax container vessel is selected for fatigue calculation. The work described in this paper is one set of results of this comparative study in which the ABS dynamics approach is applied. Through this analysis the following conclusions can be drawn. (1) With the original ABS approach, the fatigue life of this pad detail is very low, only 2.398 years. (2) The treatment of the stillwater bending moment in the ABS approach might be a source of conservatism. If the influence of stillwater bending moment is ignored, then the fatigue life for this pad detail is 7.036 years. (3) The difference between the nominal stress approach and the hot spot stress approach for this pad detail is about 26%.

  • Building above-ground membrane LNG storage tanks have been recently actively reviewed because they have advantages in ease of large capacity, environmental friendliness, and low possibility of gas leakage of the inner tank (slow increase of leakage speed). In this paper, the safety of membrane LNG storage tanks was ensured through comparative risk assessment of full-containment LNG storage tanks and membrane LNG storage tanks by using Fault Tree Analysis (FTA). Risk assessment results showed that both types of tanks have very similar level of risk except for the membrane storage tanks without additional safety equipments (early model).

  • In this study, we applied DRASTIC and SINTACS models for the assessment of groundwater vulnerability to Buyeo-eup area in Buyeo-gun, Chungcheongnam-do, Korea. Currently, DRASTIC model is a main tool for the assessment of groundwater vulnerability, which has been widely applied for the multiple purposes related to local developments, construction projects, groundwater investigations, etc. since 1980s. Because DRASTIC model has been the sole tool used for the domestic environment, there has been doubt about the degree of reliability of the model, and a benchmark model has been sought by the many practitioners. The objective of this study is to check the applicability of SINTACS model to domestic environment, which is the first attempt in Korea as far as authors understand. The comparative results show that the DRASTIC assessment underestimates groundwater vulnerability of the aquifers composed of fractured bedrocks while that from the SINTACS model is relatively higher. Through this study, it is expected that SINTACS model serves as a reasonable alternative of DRASTIC model where the subsurface is composed of more than two different media such as fractured rocks and alluvium.

  • The paper is describing work being developed in the frame of a 5-year IAEA Coordinated Research Programme (CRP) started in late 2005. Participants gained knowledge of modelling methodologies and experience in the development and use of rather sophisticated simulation tools in support of site characterization and performance assessment calculations. These goals were achieved by a coordinated effort, in which the advantages and limitations of numerical models are examined and demonstrated through a comparative analysis of simplified, illustrative test cases. This knowledge and experience should help them address these issues in their own country's nuclear waste program. Coordination efforts during the first three years of the project aimed at enabling this transfer of expertise and maximizing the learning experience of the participants as a group. This was accomplished by identifying common interests of the participants (i.e., Process Modelling and Total System Performance Assessment methodology), and by defining complementary tasks that are solved by the members. Synthesis of all available results by comparative assessments is planned in the coming months. The project will be completed end of 2010. This paper is summarizing activities up to November 2009.

  • Environmental problems emerged as common global Problems awaiting solution. Active collaborative efforts are required of nations and communities In order to solve environmental problems effectively. International collaboration occurs much more commonly these days than before. and European Community(EC) mumber countries are no exceptions. EC has established and executed the five-year programs on Environmental Policy Implementation, which explicated basic principles for enoronmental policy development, stance 1973. EC programs tend to emphasize that the direction of the policies should reflect a change from a remedial approach to a preventive approach. Those pro- grams have brought an awareness of the Importance of Environmental Impact Assessment(EIAI to EC member countries. France Installed an EIA system In 1976, which was the first among member countries. Several other member countries also established a system. EC decided that a common guideline was necessary. and therefore formulated the "European Community Guideline for Environmental Impact Assessment" In 1985. All member countries were required to legislate an EIA system within three years, according to the Guideline. This study will conduct a comparative analysis of the current EIA systems of different EC member counties. The findings of this study will provide helpful Information on how to Improve the efficacy of the Korean system.an system.
