A objective quality assessment for the evaluation performance of a video transmission system as a basic step for construction of digital video transmission system between the spots and headquarter. Due to a limit of an analog video transmission system and the developments of various digital media and digital video standards, the need of introduce of a digital system are increased gradual1y, At this points. previously performance evaluations are performed and the quality assessment is the most important thing. We can be divided quality assessment method by the subjective quality assessment and objective quality assessment. The subjective quality assessment method has some problems which are required high cost and much time to evaluate the quality, And because existing objective quality assessment method such that PSNR are based on an analog form, the correlation with subjective data is very low. Therefore we design a new objective quality assessment method using Gabor wavelet transform reflecting HVS(Human Visual System), Designed objective quality assessment method is superior to other objective method such that PSNR or EPSNR In this paper, we proposed objective quality assessment using Gabor wavelet can be used for performance evaluation and verification of video transmission system.

To evaluate the oral health status and to assess the resultant dental treatment needs in adolescents, 2,062 adolescents aged 14-17 years attending middle and high schools in Yangsan were surveyed by clinical examination and questionnaires. The obtained results were as follows. In the dental caries examination based on WHO criteria, the treatment needs of 66.7% of the subjects were determined. Assessment of dental erosion by the VEDE system indicated the treatment needs in 27.8% of the subjects, while MIH examination based on EAPD criteria indicated the treatment needs in 14.7%. Assessment of malocclusion using the occlusal index showed good occlusion in 67.8%, no need for treatment in 19.7%, slight need for treatment in 6.8%, definite need for treatment in 4.5%, and worst occlusion in 1.1% of the subjects, showing 12.5% of average treatment need. The prevalence and treatment need for periodontal disease was found to be 71.2% by CPITN assessments. The assessment of temporomandibular disorders by Helkimo's anamnestic index showed no symptoms in 67.1%, mild symptoms in 13.4%, and severe symptoms in 19.5% of the examinees. The overall treatment need of TMD was 20.6%. Periodontal diseases were ranked the highest in treatment need, followed by dental caries, dental erosion, MIH, TMD, and malocclusion in order. The results of this study indicated the overall status of adolescents'oral health and dental treatment needs. These might hopefully provide fundamental data and contribute to establishing promotional projects for adolescent oral health in Korea.

Purpose : Cancer, one of the major causes of death in Korea, tends to become chronic due to the rapid development of diagnostic and therapeutic methods. As a result, the number of home-based cancer patients is in the increasing trend. However, on account of the insufficiency of continuous and comprehensive cancer patient management system, a number of cancer patients are left in a defenseless state. This study was designed for need assessment of home-based cancer patient to establish the community-based health care system for the comprehensive and continuous health care service to improve the quality of life of cancer patients and reduce rare burdens of their families. Methods : Through making a survey for needs assessment toward the health care service, the 455 respondents among home-based cancer patients answered the given enquetes to analyze the management status and problems of home-based cancer patients Results : 1) Unsatisfaction rates of pain control is 25.5 percent for mild cases, 46.5 percent for severe cases. 2) According to the needs assessment of home-based cancer patients, most of the respondents want to receive economical support, alleviation for the pain and symptoms, and the information of health care and consultation. So these needs account for the main contents of the home-based cancer patient management plan. 3) In the aspect of the satisfaction rate for basic care need, most items account for $20{\sim}30%$ of satisfaction. And the proportion of need for special case is under 5%, satisfaction rate for special care need is about 50% of satisfaction. So the home-based cancer patients are not being cared sufficiently. Conclusion : According to the result of need assessment, many home-based cancer patients received inadequate pain and symptom management. And Satisfaction rate for basic and special care need is low. So development of comprehensive and continuous health care service to improve the quality of life of cancer patients and reduce care burdens of their families is very necessary.

Purpose: The self-assessment ability of students is important in acquiring clinical skills. The study explored the self-assessment behavior of nursing students after OSCE (Objective Structured Clinical Examination). Methods: The participants were 90 nursing students. They assessed their performance just after an OSCE (assessment 1). They were given OSCE checklists and re-assessed their performance level (assessment 2). Assessments 1, 2, and an assessment by professor were compared and analyzed. Results: Students assessed themselves higher than professor. But, when students were divided into three groups according to score level, different behaviors were evident between the groups. The high-score group assessed themselves lower than the professor, while the mid-and low-score groups assessed themselves higher than the professor. Students' self-assessment more closely approximated the professor's assessment when they were given checklists. The correlation between assessments 1 and 2 was stronger in high-score group and weak in low-score group. Conclusion: The study results indicate that students tend to assess their skills higher than the professor, but their scores were more in line with the professor when they were provided with checklists, and students' self-assessment behavior differed in the different score groups, suggesting a need for customized feedback and a concern for students with low scores.

Due to the recent aging population, the need for development and use of welfare technology is increasing in society, but the debate on the evaluation of the personal, social and economic effects of newly developed welfare technology is insufficient. The purpose of this study is to analyze the concept of welfare technology and the theoretical contents of technology assessment, and to discuss the development of indicators applicable to welfare technology assessment for older adults. For this purpose, the characteristics of welfare technologists, who are distinguished from the general technology, were examined and tried to establish the concept of welfare technology and to examine theoretically. In addition, welfare technology Assessment indicators reflect the characteristics of older adults and are presented in six areas, including personal, economic, social, technological, environmental and ethical aspects. For the case study, two welfare technology products for older adults were selected and applied to the welfare technology evaluation indicators. This study suggests that older adults and their caregivers need to be participating as an important stakeholder to increase the effectiveness of the welfare technology assessment.

This study diagnosed the status of marine environmental impact assessment(MEIA) for project near the habitat of marine protected seagrass species such as Zostera caespitosa, Zostera asiatica, Phyllospadix iwatensis. For the preparation of a marine environmental impact statement, different monitoring parameters are used without any specific guideline for the assessment of current status. And also, both tools and techniques for MEIA are needed to improve for implementing. The monitoring plans and parameters are not considered well with the accuracy of the environmental predictions and effectiveness of any applicable mitigation measures. This study suggested the reasonable standard of the MEIA for the conservation of the marine protected seagrass species which have the habitat located near affected area. The inshore seagrasses need to be monitored including shoot count based on the "No Net Loss of Seagrass" as part of the monitoring parameters to assess the status of marine environment of environmental impact statement. In a process of effect prediction, we suggested a concentration of 10 mg/L suspended solids which added by the new developmental project near seagrasses habitat, referring to study of overseas case. But a further study for an appropriate standard is necessary effectively. In a mitigating process, priority needs to be considered in order of avoidance, minimization, reduction, compensation. In a post-monitoring process, it is necessary to monitor the seagrass species abundance to identify the variation of b/a (before and after) project. And in a case of implementing transplantation, survival rate need to be included to determine a success of project.

It has been pointed out that the process of environmental impact assessment in Korea has been less of equity and balance between stakeholders, and less of objective validity in writing impact statement and in holding consultations. Thus this study has intended to find improvement measures regarding the processes of EIS documentation and holding consultations between stakeholders during environmental impact assessment process. To achieve this goal this study carried out expert survey method to analyze validity and suitability of suggested measures in accordance with the problems found through reviewing related literatures. This study has found major improvement measures including transferring the responsibility to write impact statement and to hold consultations from project promoters to the third party (impact assessment committee) composed of related stakeholders without project promoters. The developers need to pay for all expenses to proceed impact assessment.

The 7th national curriculum shifts the fundamental spirit from teachercentered to learner-centered instruction. According to the shift, performance assessment has been emphasized in schools rather than using a variety of standardized tests. However, some researchers and educational policy-makers recently asserted that we need to return to the kind of standardized tests used in the past, giving up performance assessment, for it can actually not be implemented in classroom. This paper is written to refute their assertion. Performance assessment prove one's real worth when it is implemented in learner-centered instruction. Therefore, some assessment methods are discussed which can be used during learner-centered instruction.

Private stevedoring companies are leasing and operating the container terminals of the Busan Port. The total amount of lease fees private stevedoring companies paid in 2010 reached 161 billion wons, an approximately 66 percent of the total revenue of the Busan Port Authority(BPA). In other words, lease fees are the most important revenue source for BPA. However, the lease fee assessment system of Busan container terminals goes against the principle of equity due to different assessment methods and criteria adopted by each container terminal. Therefore, the purpose of the study is to analyze the systematic problems of the lease fee assessment system that is used at Busan container terminals, and propose a new standardized scheme with a case study on the new system. In order to standardize the assessment system, the assessment methods need to be simplified by using the Discounted Cash Flow(DCF) method. In addition, the assessment criteria such as assessment duration, discount rates, price indexes, estimated container throughputs, sales unit price per TEU, operation costs, including labor costs, need to be standardized as well. The new standardized assessment system can be applied to estimate lease fees for new terminals. However, for existing terminals to run the new system, factors such as assessment duration, discount rates, price indexes, estimated container throughputs, investment and re-investment costs, and maintenance & repair costs of the new system should be changed slightly.

This study was done to evaluate the need and satisfaction for nursing care of the families with their hospitalized children. The data were collected through the questionnaire from March 15, 2002 to April 7. Subjects were the 103 families caring for their hospitalized children at pediatric ward in two university hospitals in Daegu. The nursing need instrument was developed by Seo(1999) and modified by the researcher of this study based on the classification of nursing care area(nursing assessment, direct nursing, education and counseling, and facilities and environment). The nursing satisfaction instrument was developed by Wandelt & Ager(1974) and modified by Park(1994) based on classification of nursing care area (psychosocial care, physical care, general care, professional care, and communicative care). The data were analyzed for mean, percent, t-test, ANOVA, and Pearson correlation coefficient using SAS program. The results are summarized as follows: 1. The scores in the nursing need showed in the Direct nursing(3.41±.42), Facilities and Environment(3.38±.46), Education and Counseling (3.35±.40), and Nursing Assessment(3.14±.41) area in order. 2.The scores in the nursing satisfaction showed in the Psychosocial care(3.70±.74), Commu- nicative care(3.60±.72), General care(3.42±.76), Professional care(3.38±.82), and Physical care(3.32±.70) area in order. 3.General characteristics of families which influence on the satisfaction showed a significant difference according to their educational(F=5.63, p=.001) and economical level(F=4.47, p=.006), and hospitalized experience(t=2.30, p=0.02). 4. There was no correlation between the nursing need and the nursing satisfaction.
