A Spent Fuel Pool (SFP) is designed to store spent fuel assemblies in the pool. And, a SFP cooling and cleanup system cools the SFP coolant through a heat exchanger which exchanges heat with component cooling water. If the cooling system fails or interfacing pipe (e.g., suction or discharge pipe) breaks, the cooling function may be lost, probably leading to fuel damage. In order to prevent such an incident, it is required to properly cool the spent fuel assemblies in the SFP by either recovering the cooling system or injecting water into the SFP. Probabilistic safety assessment (PSA) is a good tool to assess the SFP risk when an initiating event for the SFP occurs. Since PSA has been focused on reactor-side so far, it is required to study on the framework of PSA approach for SFP and identify the key factors in terms of fuel damage frequency (FDF) through a case study. In this study, therefore, a case study of SFP-PSA on the basis of design information of APR-1400 has been conducted quantitatively, and several sensitivity analyses have been conducted to understand the impact of the key factors on FDF.

Capstone design is a subject taught in a setting where students gather in a team, decide on their own selected topic, and collaborate with one another to perform a project. A fair assessment is very important in a team project-based capstone design course for students. Many instructors agree that harmonizing creative evaluation and outcome assessment is hard in capstone design class. In also, it is not easy to assess students' individual efforts and achievements fairly in accordance with team-based assessment practices. To resolve this issue in this paper, we have surveyed various engineering design education methodologies, and have modelled existing evaluating elements into a modified creative process and outcome assessment framework for team project assessment. In particular, we focused on a method of fairly assigning credits by combining team based and individual-level assessments. Analyzing students' achievement and grade evaluation and verifying the validity of the proposed method was performed.

As global competition is more intensive, SCM is becoming more and more important in order to achieve competitiveness. It is necessary for firms to understand weak points among the integrated supply chain through supply chain assessment in order to implement SCM successfully and cost-effectively. In this paper, we review previous studies of SCM performance measurements and propose a supply chain assessment framework for shipbuilding industry, which is one of the major ETO industry. Based on 3 supply chain domains which are demand, supply, and product management, we decompose the whole supply chain process into 3 level lower processes and propose capability measurement matric for shipbuilding firms. A case study has been conducted to validate the proposed framework and results are presented at the end.

This paper presents an analytical framework of Conceptual Understandings of Earth Systems (CUES) that shows a relationship between disciplinary knowledge of Earth systems and the specific thinking skills required to understand that knowledge. This framework is developed through an extensive literature review of students' and teachers' understandings of earth systems concepts and systems thinking in earth science context. This study first presents the categories of disciplinary knowledge of Earth systems, Earth System Knowledge (ESK). This study then illustrates a relationship between categories of ESK and the ontological categories (Matter, Process, Systems) that has been used to study students' conceptual understandings of Earth systems. Finally, this study presents the CUES framework to show the relationship between disciplinary knowledge and thinking skills. The implications of using this framework for curriculum development, assessment, and teacher education and ESS research are discussed.

This study introduces the framework of the mutual recognition project of APEC Engineer and also tries to find out what we, Korean engineers have to do with this project. The mutual recognition framework consists of 2 main frameworks ; the substantial equivalence framework and the mutual exemption framework. The participating Economies have discussed and agreed on the framework of the substantial equivalency and have been producing APEC Engineers from the 1st, Nov 2000 based on this agreement. However, more discussions will be required from now on in order to finalize the mutual exemption agreement, even though there have been a lot of discussions including the workshop for the regulatory authority for the last 5 years. Here we have to study and find out what we have to do with this project and prepare for the bilateral agreements and the Coordinating Committee meeting to be held in Hongkong in Oct this year.

The Emergency Diesel Generator (EDG) is a critical and essential part of the Nuclear Power Plant (NPP). Due to past catastrophic disasters, critical systems of NPP like EDG are designed to meet high dependability requirements. Therefore, we propose a framework for the dynamic reliability assessment using the Fault Tree and the Dynamic Bayesian Network. In this framework, the information of the component's failure probability is updated based on observed data. The framework is powerful to perform qualitative as well as quantitative analysis of the system. The validity of the framework is done by applying it on several NPP systems.

This work proposes a theoretic framework for the performance assessment of an access point in the IP network that accommodates MD (Machine Data) and HD (Human Data). First, we investigate typical resource allocation methods in LTE for MD and HD. After that we carry out a Max-Min analysis about the surplus and deficiency of network resource seen from MD and HD. Finally, we evaluate the performance via numerical experiment.

Background: Work-related stress is one of the major causes of occupational ill health. In line with the regulatory framework on occupational health and safety (OSH), adequate models for assessing and managing risk need to be identified so as to minimize the impact of this stress not only on workers' health, but also on productivity. Methods: After close analysis of the Italian and European reference regulatory framework and workrelated stress assessment and management models used in some European countries, we adopted the UK Health and Safety Executive's (HSE) Management Standards (MS) approach, adapting it to the Italian context in order to provide a suitable methodological proposal for Italy. Results: We have developed a work-related stress risk assessment strategy, meeting regulatory requirements, now available on a specific web platform that includes software, tutorials, and other tools to assist companies in their assessments. Conclusion: This methodological proposal is new on the Italian work-related stress risk assessment scene. Besides providing an evaluation approach using scientifically validated instruments, it ensures the active participation of occupational health professionals in each company. The assessment tools provided enable companies not only to comply with the law, but also to contribute to a database for monitoring and assessment and give access to a reserved area for data analysis and comparisons.

In order to prepare for the coming twenty-first century and to meet changing social demands and health needs, it is necessary to improve the curriculum through development of new conceptual frameworks. The purposes of this study were : 1) to assess the needs of the curriculum of the students, the faculty, the graduates, and the nursing supervisors and head murses ; 2) to develop the conceptual framework which includes philosophy and goals of nursing education based upon needs assessment ; 3) to develop level objectives ; 4) to identigy the contents of the curriculum ; 5) and to develop the faculty. The curriculum was assessed and developed from April, 1995 to March, 1996 through twenty four weekly meetings, two seminars, and two workshops. The process and results of this study are as follows : 1. A needs assessment of the present curriculum was done of the 194 students, 177 graduates, 14 faculty members, and 60 nursing administrators in 5 main areas (objectives, planning and organization, teaching-learning process and methods, evaluation, revision of curriculum). The results showed that there were many descrepancies between expectations and actual situations in all the groups and in all the areas. This implies that there was a necessity for total curriculum revision. 2. To develop the conceptual framework, 1) the core concepts were identified(man, health, environment, and nursing) on the basis of the existing educational philosophy and educational objectives of our school, elicited by group discussions using the nominal group method, one of the needs assessment methods, the philosophy and objectives were restated. 2) Six essential componednts were indentified for the conceptual framework from the restated philosophy and objectives ; nursing process, communication, professional roles, client, health, and nursing. The vertical theread consists of the client and health/nursing ; and the horizontal thread consists of nursing process, communication, and professional roles. 3. The contents of the curriculum were selected on the basis of the educational objectives and organized according to the conceptual framework. 4. The level objectives were then restated. It is expected that the objectives of our school will be accomphished through developing the courses, choosing and Implementing, more effective teaching-learning methods, and evaluating the efficacy of changes implemented. The most important factor will be to continually upgrade the faculty and their teaching skills.
