  • In Jeju power sytstem, the generation of reactive power depends on the operation of CSC-HVDC filter. Thus, the grid voltage will be affected. Statcom and SVC have demonstrated that it has excellent charateristics to solve this problem. First, this paper analyzes the operation of the Statcom based on the real power system in Jeju. Then, the characteristics of Statcom will be compared to the SVC. The modelling of the Jeju power system including Statcom and SVC will be performed by using PSCAD/EMTDC program and the real data from the real Jeju power system.

  • Since the economic crisis in 1997, the number of low income families has increased and the turmoil is likely to affect nutritional and health status of the children in low-income families. The purpose of this study was to investigate dietary behaviors and physical development of low income family children in the Seoul area. The subjects were 44 boys and 56 girls, between the ages of 7 and 12 years, from the beneficiary families of the governmental assistant program and enrolled in after school-care centers. A self-reported questionnaire, including general characteristics and dietary behaviors, was applied to the children and their parents. Skipping meal rate was higher in breakfast than in lunch or dinner, and was less frequent in parents and children families compared to that of the other types of families (p<0.05). Most students are shown that they usually keep the dietary guideline for Korean children. There were significant differences in keeping the dietary guidelines between the parents and children family group and other groups in several items. The results imply that the nutrition education program should be more focused on the families which are not composed of parents and children.

  • Purpose: The purpose of this study is to identify the current status and use of Gyungrodang located in Heungeop-myeon, Wonju-si and to present improvement and implication for community care in rural area. Methods: The survey of the current status was conducted with interview and observations. The use status of Gyungrodang was surveyed for the elderly over 65 years old who live in Heungeop-myeon using questionnaire. A face-to-face interview was conducted to complete a questionnaire and 181 samples were collected for the study. Results: In the current status, some of the Gyungrodang did not operate during farming season. The external environment, in terms of accessibility, 74.2% of Gyungrodang were located more than 60 minutes on foot from community center, health post, and pharmacy. In addition, the interval between buses run minimum 15 minutes to 120 minutes on average. The internal structure, 35.7% was divided room and toilets. In the use status, the reason for non-use of the Gyungrodang was discomfort(29.0%), and the reason for using was because friends go to the Gyungrodang(44.6%). The most satisfying program was te health care program(65.6%). Implications: First, it is necessary to develop and operate customized health promotion program for target population and seasons. Second, it is necessary to make a plan focused on consumers' needs through satisfaction and demand survey. Third, it is necessary to divide the space of each Gyungrodang by gender when planning the expansion or new construction of Gyungrodang.

  • Recently, safety-critical aviation system development programs promoted domestically have been terminated in the middle stage or they have not been put to practical use at the final stage. The program failure may be caused by various factors, but this study focused on imperfect test and evaluation(T&E) procedures. In general, T&E process of a safety-critical system must be distributed throughout the entire life-cycle of the system, have a continuity in phases, and can be implemented in a variety of ways depending on the maturity of the system development and acquisition strategy. This paper aims to present a new strategy by analyzing the domestic and overseas T&E processes to reduce the risk of domestic safety-critical CNS/ATM system development program and increase the success rate of program. First, we discuss the verification and validation techniques for safety-critical systems, analyze the T&E procedures of advanced institutes and the domestic situation, and then compare the domestic and overseas T&E processes to complement the imperfect testing procedure.

  • Although occupational accidents caused by presses are found to be the highest in manufacturing industrial groups, there are no study regarding to annulment for periodical inspection of press. The purpose of this study was to evaluate the economic benefit of periodical inspection of press for preventing accidents. The cost-benefit analysis in this study was conducted to evaluate the relative magnitude of benefit to cost. Study samples were 26 and years analysed were 1995, 1996, 1998 and 1999. Personal interviews with safety managers were held from October 7 to November 2, 2002. Costs of the periodical inspection program were compared with the benefit of accident that caused by presses. Costs and benefits were calculated at an discount rate of 5%. The benefit-cost ratio was 5.7. The sensitivity analysis for the discount rate, the number of press, and size of industry showed that every benefit-cost ratios were upper than one(1.0). The results of this study suggested that periodical inspection for press is important program for preventing accident and the regulation for periodical inspection program should be reenforced by government.

  • Purpose: This study was conducted in order to examine how an effective rehabilitation exercise program influences the activity of shoulder muscles, and to help the clinical application of a rehabilitation program, for prevention and relief of pain, adhesion, and joint stiffness of patients who undergo rotator cuff repair. Methods: Nine test subjects were placed randomly into each group for a total of 27 subjects and exercise program interventions according to the group were conducted for six weeks, after which maximum voluntary isometric contraction (%MVIC) value was re-measured for supraspinatus muscle, infraspinatus muscle, serratus anterior muscle, and middle deltoid muscle in all groups in order to compare changes in muscle activity before and after the experiment in order to perform comparative analysis of changes in muscle activity between groups, based on which four experimental hypotheses were confirmed. Results: Changes in muscle activity according to %MVIC showed a statistically significant difference (p<0.01) (p<0.001) in all muscles, except the middle deltoid muscle, and post-verification results showed that changes in muscle activity according to %MVIC were greater in test groups I and II, compared with the control group, for the supraspinatus muscle, infraspinatus muscle, and serratus anterior muscle. Conclusion: Therefore, rehabilitation through use of the methods described above should be applied efficiently in clinical settings and more research in development of much more efficient rehabilitation program interventions must be conducted.
