The Risk assessment regulation(RAR) is one of the essential articles of the Occupational safety and health law for the construction industry along with safety and health management expense and safety organization regulation. However, arguments regarding the working time of the safety assessment documents, the person in charge of documentation, weakness in legislative enforcement etc. are ongoing. Thus this study aims to analyze the effectiveness of RAR for the guidance of enhancing the effectiveness of RAR. The findings are; 1) the effectiveness of RAR is recognized, however the indirect effectiveness ie, enforcement of safety activities, previewing of drawings etc. are bigger than the direct effectiveness of accident prevention, 2) to enhance the effectiveness of RAR site inspection procedure has to be utilized, 3) further research for identifying and getting rid of negative factors in RAR is recommended.

Purpose: Root cause analysis (RCA) refers to any systematic process that identifies the causes that contribute to a focus event. The immediate cause of a focus event is often a symptom of underlying causes and may not truly identify the root causes that should be identified and addressed. Currently many RCA tools are available. Different investigators use different RCA tools on different issues. No standardized or commonly agreed way to analyse root causes exists. The purpose of this study is to propose the methodology of RCA process commonly useable for various issues. Methods: The methodology of RCA process is produced based on the hybrid RCA tools. The effectiveness assessment matrix of actions through the root cause candidates is presented. Results: No single RCA technique proposed has so far covered all necessary aspects. A hybrid approach which combines the best features of various techniques is proposed. The effectiveness assessment matrix helps us to identify the root cause to correct or eliminate system vulnerabilities effectively. Conclusion: This hybrid approach and effectiveness assessment matrix can provide guidance of RCA process across many industries and situations.

Environmental Impact Assessment(EIA) was first formally established in the Korea in 1981. Subsequently there has been a rapid growth in EIA activity, and over one hundred fifty environmental impact statements are now published in Korea each year. Although EIA now has almost 20 years of history in the Korea, elsewhere the development of roles and practice is more recent. Development is moving apace in many countries, including the Japan and the EU Member States. Such progress has not been without its problems, and a number of the current issues in EIA-scope of the assessment, the relative roles, the quality of assessment and monitoring and auditing after decision, and so on- are highlighted. So the purpose of this article is to reform the EIA roles and process, in extending the scope of activity, and assessing effectiveness. This article suggested improving the effectiveness of project assessment, widening the scope: stretegic environmental assessment, and extending EIA to project design process, environmental monitoring and feedback system.

This study analyzed the factors affecting the effectiveness of the Chemical Hazard Risk Management (CHARM). A survey was conducted on 104 learners who participated in the Risk Assessment training course at Occupational Safety and Health Training Institute. Through a self-administered questionnaire, the effect of personal characteristics, corporate characteristics, and safety and health level of the company on the effectiveness of chemical risk assessment was investigated. As a result of statistical analysis, the safety and health level of the company had a positive (+) effect on the effectiveness of Chemical Hazard Risk Management(CHARM), but personal characteristics and corporate characteristics had no relation to it. This study can be used as basic data for further research related to chemical risk assessment in workplaces.

Peer assessment is the process of assessment of students by other students and one form of innovative assessment. It actively involves students in the assessment process and is generally agreed that such involvement enhances the quality and effectiveness of the learning process, since assessing something and benchmarking process is a powerful aid to mastering it themselves. It is more effective on the hard courses for them to understand. In this article we present a peer assessment technique which was applied to students enrolled in a mathematical statistics course and a historical course. In order to measure the effectiveness of the technique, students had to evaluate their colleagues based on predefined criteria and a comparison is presented between the instructor assessments and the peer assessment.

This study aimed to develop and apply the process-focused assessment, and verify the assessment's effectiveness for improving scientific communication skills in elementary science learning. To achieve the aims of this study, the unit "Action of Electricity" in elementary science text book for 5-6th students was selected, and then 13 process-focused assessments were developed to improve scientific communication skills. 119 elementary school students in 6th grade participated in this research. it was performed to compare between 60 students on the general assessment and 59 students on the process-focused assessment in the results of achievement levels on scientific concept and scientific communication skills. The results were as follows: First, this study showed that process-focused assessment had higher educational effectiveness in specific area of scientific communication skills than the general assessment. Second, the process-focused assessment can help to form students' scientific concepts as the general assessment. Furthermore, the process-focused assessment group was more effective at reducing the non-scientific concept than the general assessment.

The preliminary security assessment is an information security process to analyze security weaknesses before beginning of services. Discovering security weakness through preliminary security assessment is highly required because it costs much when security incident occur in the middle of service operation. However, this assessment is not widely spread in the online game service domain yet. In this paper, we summarize the security risk existed in the online game service, and we classify the security requirements related to the each risk. Also, through the case study, we evaluated the effectiveness of preliminary security assessment in this domain. In addition, we suggest checklists that should be reviewed once in game-client side, network-side and game-server side for the purpose of security enhancement.

The risk assessment carried out on the construction site at the beginning of the implementation depends on the subjective judgment of risk of general contractor and subcontractors, whose opinion about frequency and intensity of risk is different. In this paper, research the awareness of general contractors and subcontractors about process of risk assessment at the construction site and its effectiveness. Researching of the main factors "frequency", "intensity" which determines the degree of risk gives the opportunity to find an option for improving the effective implementation of risk assessment.
