  • Any business activities may have impact on environment to a certain extent. Enterprises must find appropriate approaches to measure the impact on these environmental aspects, which can be used as the basis to direct enterprises' efforts to improve the environmental impact. The method used to evaluate significant factors in life cycle assessment standards is the one most commonly used by enterprises in general to measure environmental impact. By this method, the decisive factors of each environmental aspect are given scores according to the preset scoring standard of the organization. The scores are added up for each aspect and ranked to assess major environmental aspects. The drawback of this assessment method, that is, it ignores the degree to which each of these factors affects the environment, results in poor credibility. Therefore, this study attempts to solve some qualitative problems by applying to fuzzy theory, in particular, by identifying appropriate fuzzy numbers through fuzzy sets and membership function. Moreover, the study seeks to obtain a crisp value in the process of defuzzifization in order to make up for the shortfall of the original method in dealing with relative weight of decisive factors and thus increase its applicability and credibility. The department of light production of an electronics company is used as an example in this study to measure environmental aspects by employing both the traditional significant factor method and the fuzzy environmental impact assessment model proposed in this study. Based on verification and comparison of results, the model proposed in this study is more feasible as it reduces partiality in decision-making by taking the relative weights of decisive factors into consideration.

  • The Web is an important source of information for health care consumers, and the resources they find on the Web have a direct affect on their health outcomes. Despite the enormous benefits of online health care, the quality of health information on the Internet is an area of increasing concern. Therefore, there's a need to develop quality assessment tools that can filter out poor quality online health information. The purpose of this study is to explore the critical attributes for assessing website quality and for developing quality assessment measurements. We completed three focus group discussions with 24 participants that were administered by a moderator and based on specifically focused group questions. The results suggest that the most important quality criteria, as identified by the respondents, were related to issues of credibility and accuracy. To determine the credibility of Internet health information, the respondents stated one must consider the following: the information source, disclosure of the author's or organization's credentials/qualifications, disclosure of ownership and the updating of the content. For the accuracy of content, elements such as a statement of purpose, evidence-based information, relevance and completeness should be considered. Interactivity, accessibility, and design were additional quality criteria.

  • 정보 교육에서 수업과 평가를 통합하는 과정지향적인 평가가 수시로 이루어지기 위해서는 평가자인 교사가 보다 편리한 방법으로 평가를 할 수 있게 지원해 주는 사용성(Usability)이 고려된 웹기반평가시스템이 필요하다. 본 연구에서는 기존의 웹기반평가시스템의 사용성 요소를 분석한 후, 오프라인 지필평가과정에 내재한 사용성 요소를 추출하여 사용성이 제고된 PBA(Paper-Based Assessment) 평가 모델을 제안하였다. PBA 모델에 의한 웹기반 평가시스템은 교사주도하에 평가전, 평가중, 평가후의 모든 과정이 제어된다. 특히 평가 대상을 손쉽게 바꿀 수 있고, 평가지에 대한 접근을 평가 단계마다 철저히 차단시켜 평가 결과에 대한 신뢰성을 높일 수 있다. 또한 학생들은 자신들의 학년, 반, 번호, 이름을 사용하여 손쉽게 평가지에 로그인할 수 있다. 본 논문에서는 이와같은 PBA 모델에 기초하여 정보교육용 웹기반평가시스템 PAS(PBA-based Assessment System)를 설계 및 구현하였다.

  • The purpose of this study is to seek the recognition and development method of the competency assessment in order to set up the competency assessment system introduced for the manager promotion in B metropolitan city. The following conclusion were obtained by studying the recognition of competency assesment system of candidates for promotion and non-candidates. First, it is found that non-candidates have a higher recognition of the necessity of competency assessment system and its credibility, fairness and influence on relieving nepotism than candidates for promotion. Second, competency factors that recognized to be necessary for the performance of manager's role were direction guidance, fostering members, integrative thinking and communication in sequence by candidates for promotion, while direction guidance, communication, integrative thinking and management of organization in sequence the non-candidates. Third, in terms of the operational aspect of the competency assessment system, both candidates and non-candidates wanted a pass rate of 70~90%. And the time required for the assessment task was most favored for 1~2hrs, and the judges of the competency assessment were preferred in the order of professors, public official, consultants, and headhunters. Fourth, $1^{st}$ candidates than non-candidates recognized that the person who are from $5^{th}$ or $7^{th}$ class appointment are younger, have high education, are better at presenting, are in administrative positions, and are more optimistic would be more advantageous in competency assessment.

  • This research analyzed the current situation and problems with an environmental impact assessment to provide a rational ocean physics assessment technique for power plant thermal effluent. This research also tried to create an improvement plan for heated effluent diffusion impact assessment by examining the reporting regulations for environmental impact assessment, national and international evaluation guidelines, etc. In the case of evaluating the oceanographic impact of heated effluent discharged from power plants, a pre-investigation is necessary before a full-scale presentence investigation, to accurately predict and minimize power plant construction effects on the surrounding environments. Before this presentence investigation, moreover, an integrated presentence plan, which agrees with the business plan, effect prediction, and post-investigation, needs to be established. A sufficient summit investigation must be made, which considers climate changes, and new and additional power plant construction. For accurate long-term oceanic environmental change prediction, the credibility of effect prediction must be elevated by presenting an evaluation method that is categorized by numerical organization models, verification methods, result presentation, and other things. Furthermore, unproductive conflicts between the people involved in heated effluent evaluation should be reduced by these improvement plans.

  • The clutch coil mounted on the automotive air conditioner is an important part which actuates the clutch to connect or disconnect the pulley and the compressor according to the climate control condition in an automobile. Here, it is generally required that the clutch coil should ensure the long term durability requirement, such as a warranty for the 10 years of field operation or 160,000 km driving, especially in a brand new item, and so forth. However, some difficulties have arisen in restoring its credibility, since domestic specifications for the part have not been yet unified. In order to ensure the reliability, test methods and assessment criteria should be standardized. Moreover, assessed lifetime under specific conditions and potential failure analysis would be important. In this study, lifetime test specifications for the clutch coil have been reviewed and methodological suggestions are provided to ensure reliability, utilizing a quality function deployment through the potential failure mode effect analysis.

  • Various problems regarding the wet floor method such as its complicated process and waste of thermal storage have been raised, but the usage of dry floor recommended for long-life housing has declined due to lack of confidence on the performance of dry floor. The purpose of this study is to secure the credibility of dry floor. Under this purpose, this study considered precedent studies and established directions to secure the performance of long-life housing infill, and thus, 9 performance items (Impact sound, Smoothness, thermal comfort, sensation hardness while walking, falling safety, impact resistance, local compression load, local strength and strain at heating) were drawn. In addition, the experiment was carried out for 5 performances except for legal performance, some dry floor performances and whole spatial performance. As a result, an appropriate result from all performances except was obtained. The performance of dry floor was verified for each item from these results and it is expected to use such results as basic data on dry floor in the future.

  • 한국원자력연구원에서는 사용후핵연료를 직접 처분하는 대신 이를 처리하여 발생하는 방사성 폐기물을 심지층에 직접 처분하는 방식의 A-KRS 개념의 방사성폐기물 처분 시스템을 개발해 오고 있다. 이러한 A-KRS 개념에 대한 장기적 안전성 및 처분 시스템 성능 평가를 위한 모델을 GoldSim을 이용 개발하고 이를 지속적으로 수정 보완하고 개선해 오고 있다. KAERI에서 개발된 A-KRS 모델의 신뢰도를 증진 시키기 위하여 유사하게 개발된 다른 모델과의 벤치마킹을 통한 비교 연구의 결과를 제시하였다. A-KRS모델을 미국 NRC에서 SwRI 연구소의 협력을 통하여 개발하여 처분 시스템 성능평가에 활용한 SOAR와 비교하고 병행하여 스웨덴의 SKB에서 최근 수행한 SR-SiTE 안전성 평가를 통하여 KBS-3 개념의 처분 시스템 내 전단 응력에 따른 용기의 파손에 따른 유출 계산 결과와도 비교 검토하여, 전반적으로 상호 잘 일치하는 결과를 얻어 내었다. 보다 개선된 GoldSim으로의 모델의 이행의 필요성은 있으나 A-KRS 모델이 GoldSim을 통해 잘 이행되어 처분 시스템 안전성 평가에 적합한 것으로 나타났다.

  • This study conducted an assessment of potential impacts on the drought in agricultural reservoirs using the recently proposed SSP (Shared Socioeconomic Pathways) scenarios by IPCC (Intergovernmental Panel on Climate Change). This study assesses the potential impact of climate change on agricultural water resources and infrastructure vulnerability within Gyeongsangnam-do, focusing on 15 agricultural reservoirs. The assessment was based on the KRC (Korea Rural Community Corporation) 1st vulnerability assessment methodology using RCP scenarios for 2021. However, there are limitations due to the necessity for climate impact assessments based on the latest climate information and the uncertainties associated with using a single scenario from national standard scenarios. Therefore, we applied the 13 GCM (General Circulation Model) outputs based on the newly introduced SSP scenarios. Furthermore, due to difficulties in data acquisiton, we reassessed potential impacts by redistributing weights for proxy variables. As a main result, with lower future potential impacts observed in areas with higher precipitation along the southern coast. Overall, the potential impacts increased for all reservoirs as we moved into the future, maintaining their relative rankings, yet showing no significant variability in the far future. Although the overall pattern of potential impacts aligns with previous evaluations, reevaluation under similar conditions with different spatial resolutions emphasizes the critical role of meteorological data spatial resolution in assessments. The results of this study are expected to improve the credibility and accuracy formulation of vulnerability employing more scientific predictions.
