보이드, 이물, 돌기 둥 고분자 절연체 내의 결함은 이곳에 전계가 가해질 때, 국부적 전계집중을 유발하며, 절연체 내의 미소 방전을 일으킨다. 이 때 발생한 미소 방전에 의해 보이드 표면의 고분자 물질은 기계적, 화학적 열화를 일으키며, 이에 따라 전기적 트리를 형성하게 된다. 이러한 트리는 결국 절연체의 절연파괴로 진전되므로, 고분자 물질을 절연물로 사용하는 전력기기의 경우에는 신뢰성에 큰 문제를 유발한다. 따라서, 이러한 방전(부분방전)이 일어날 때 생기는 전기적 신호를 검출하여, 절연물의 신회성을 평가하는 것은 매우 중요하다. 이러한 부분방전은 IEC둥 국제기술기준에 그 제한 값이 정하여져 있으며, 본 논문에서는 이러한 값을 수학적으로 평가하는 방법에 대해 연구하였다.

Landfill is an widely applied alternative for clearance of non-contaminated waste or slightly contaminated waste generated from nuclear facilities. In this study, exposure dose is estimated for a worker and a resident at the landfill area in Young-gwang nuclear power plant. Based on evaluated dose, clearance concentrations of each radionuclide are determinated for dose criteria of 10 $\muSv/y$. The results of age-dependent dose are 1.02 $\muSv$ per year for resident and 0.471 $\muSv$ per year for worker. Clearance concentrations for each radionuclide are evaluated from $1.33{\times}10_{-1}$ Bq per gram to $2.85{\times}10^2$ Bq per gram.

웹의 다양한 자원을 이용하여 고성능 작업 처리를 요구하는 분산/병렬 시스템은 균형적인 작업 할당을 위해 각 호스트의 성능 평가가 중요하다. 하지만 성능 평가에 대한 지속적인 신뢰하기가 어려우며 뿐만 아니라, 작업 도중 호스트의 성능 변화를 예측하기가 어렵다. 성능 변화에 따른 효율적인 작업 스케줄링이 필요하며, 자원 관리자는 작업을 수행중인 호스트에 대한 모니터가 요구된다. 본 논문에서는 자원 관리자와 시스템 관리자에게 효율적인 자원 정책을 제안하기 위해 각 호스트의 자원을 모니터하고, 분산/병렬 시스템의 작업 할당 메커니즘에 의해 각 호스트의 성능 평가 기준을 정한다 또한 관리자에게 실시간으로 호스트의 성능 변화에 따른 자원 정보를 관리하도록 다양한 시각화를 제공한다.

This study attempts to extract the necessary criteria as a secondary school home economics teacher through the factor analysis, and to analysis the teacher's and student's perceptions for the requirement criteria of home economics teacher(RCHET) thereof to confirm the necessary criteria as a secondary school home economics teachers. This research was based on the requirement criteria of home economics teacher developed by Korea Institute for Curriculum and Evaluation(KICE) Korean Home Economics Education Association(2008)(KHEEA) collected from secondary, upper secondary school home economics teachers and students in Jeollabuk-do. RCHET encompasses the six areas : (l)'Expert of lesson related to evaluation' (2)'Efficient manager of diverse materials for study', (3)'Student advisor equipped with a teaching sense of duty and sound humanity', (4)'Curriculum expert equipped with a expertise knowledge', (5)'A fair and democratic schoolroom environment promoter'. (6)'Career path counselling expert understanding student's characteristics and environments'. Through the factor analysis, six RCHET factors are more important to teachers than students. According to importance perception for RCHET, home economics teachers' qualification for minor second subject and participation of training program showed similar differences statistically in all RCHET factors. Thus, effort for expertise improvement of teacher had important influence on expertise improvement of teacher. As a result of examining the differences from importance evaluation for RCHET, similar differences from frequence of home project, preference of home economics teacher, manual training and home economics score, interest of home economics showed statistically.

Current performance evaluation of the natural science section mainly focuses on teacher evaluation, which causes slow feedback on the evaluation result and little evaluation on colleagues due to limits of time and space. In addition, report performance evaluation, which is a main target of the evaluation in the natural science section, is conducted mostly based on records of experiments and observation without any systematic forms. Such performance evaluation cannot meet expectation on the evaluation for a self-adjustment through instant feedback on the evaluation result and improvement of motivation through sharing common performance standard. Therefore, the study here completes an experiment/research report through information sharing and discussion among colleague learners based on the web and uses it for colleague or teacher evaluation. In addition, it is intended to recognize needs of learners and develop a performance evaluation system that can provide learners with appropriate feedback through the result.

The importance of Digital Rights Protection technologies, especially the forensic marking, is getting larger and larger as the demand for the digital contents is increased. But the technologies for the evaluation of forensic marking is not set up properly due to the conflicts between interested parties and technical difficulties. Therefore to evaluate the performance of forensic marking objectively, image and video modification items/levels and evaluation criteria are essential. This paper suggests the quantitative system for evaluating the performance of forensic marking objectively. By providing the opportunity to evaluate the Digital Rights Protection product in objective and quantitative manner, forensic marking industry can expedite its technology development and consumer can get objective and universally validated performance result. It is expected this technology could help revitalizing the related industries and help expediting the development of forensic mark technologies.

General finger splint manufactured and sold domestically could have been of great help to patients with disabilities due to damage to the body's. However, it reminded the wearer of his disability that he wanted to hide. This has had a negative effect on the psychological side of self-absorption and depression. If this avoids or rejects wearing, the role of ancillary rehabilitation is lost. This does not meet the user's requirements. Thus, in this study, 3D printing was used to better reflect user requirements. Next, the study examined existing prior studies to identify the characteristics and criteria of each study. It also examined medical finger aids that were being sold in the auxiliary device market. The assessment criteria were derived by compiling and interpreting user surveys of each finger splint device. Based on the evaluation criteria derived, the design guidelines for finger splint were presented using FDM-style 3D printers. Finally, we proposed a finger splint design according to the proposed design guideline.

Digital Printers that are mainly used in enterprises and public institutions are compound machinery and tools which are combined into various functions such as printing, copying, scanning, and fax so on. Digital Printers has security functionality for protecting the important data related with confidential industry technology from leaking. According to the trends, CC(Common Criteria) evaluation and assurance about digital printer is on progress in Japan and USA. Domestically CC evaluation and assurance is started recently. However, the know-how about the digital printer evaluation is not enough and the developers and the evaluators have difficulty in CC evaluation of digital printer products in the country. Therefore, the testing method of digital printer security functionality and evaluation technology is essentially needed for increasing demand for the evaluation afterwards. In this study, we analyze the security functionality and developing trends of digital printer products from internal and external major digital printer companies. Moreover, we research the characters of each security functions and propose guideline for digital printer security functionality evaluation and vulnerability testing methods.

Since 1960's, international construction market have explosively increase and have reached up to 600 Bil. US$ through active participation of construction firms and steady support of government. Nevertheless, owners, clients and financial institutions required reasonable criteria to effectively assess the overseas business capabilities of construction firms. However, the existing methods for construction firms rarely considers the perspective of overseas business capabilities. To overcome these problems, this study proposes an evaluation system for overseas business capabilities of construction firms. First, the needs for new evaluation system is derived through FGI, and the direction of new evaluation system is presented by reviewing the limitations of existing methods. Also, the capabilities that are required for the performances for overseas businesses were analyzed through expert interviews. Finally, 31 primary evaluation indices consisting of 3 criteria - appropriateness of index, possibility of quantification, possibility of data gathering - are derived under 9 categories and 3 perspectives through surveys and consultation meeting. The preliminary investigation of 24 Korean construction firms are conducted for comparing the existing evaluation systems and to verify its applicability. The proposed method could provide a rational criterion to evaluate the construction firms, improve internal capacity of firms, and ultimately supports the success of the construction industry.
