  • This article reviews the recent activities of field testing and application of superconducting fault current limiters (SFCL) based on high-temperature superconductors (HTS). The review particularly focuses on the trends in the field tests in terms of the technical aspects and commercial activities of the SFCLs. Stimulated by the discovery of HTS, numerous research and development activities have been conducted worldwide for SFCLs operating from distribution voltages to transmission voltages. Different types of SFCLs have been developed and field-tested. Consequently, more than 20 field tests and applications have been performed on real grids worldwide while supplying electric power to the customers. These field tests have not only provided the track records of the operation experiences including the problems and maintenance during operation, but also proved their current limiting capabilities against real faults, rendering this new technology highly viable. Through these activities, the following trends in the status of field testing and application are observed. Resistive-type SFCLs with HTS-coated conductors were dominantly used in the most recent field tests. This implies that the resistive type is technically more mature than the other types. Bus-bar coupling and transformer feeders were the major application locations. It is of importance that most of the field applications were conducted as R&D projects. A relevant change from the R&D stage to the application stage is shown as recently deployed SFCLs are expected to be under long-term operation and commercial service. Here, we review the installation of these SFCLs by substation. This review also discusses the recent activities for their commercial applications.

  • The statistics of traditional korean medicine is essential aspects for the information based policy establishment and the evidence based traditional korean medicine research. But because the integrated statistics service of traditional korean medicine is not provided, people are hard to find out suitable statistics. Thus we analyzed the produced statistics from many ministries, classified it into 7 categories and extracted common fields from it. We designed the database schema by summary table dynamic production method from the analysis of statistics and designed the system composed of excel import, statistics analysis, chart creation and search engine. Finally we implemented the statistics system of traditional korean medicine which users are capable of modifying the statistics data freely. We hope that the implemented system will provide pliability in searching and finding statistical information.

  • Cardiac cathererization has become a routine diagnostic procedure indicated for evaluation of a wide varity of cardiac conditions. Patients are admitted to the coronary care unit after cardiac catheterization. These conscious patients report feeling uncomfortable in the CCU, but no studies have been done on the effects of bed rest, sand bags on the femoral puncture site and restricted mobility for 4 to 12 hours or longer postprocedure. The main objective of this thesis is to provide basic data to nursing on interventions which de-crease the uncomfortableness experienced by patients in the CCU following cardiac catheterization. In this phenomenological study, the various discomforts felt by the patients were collected and classified. The study subjects were a convenience sample of 29 patients who were admitted to the CCU of a general hospital in Inchon following cardiac catheterization. They were conscious, so they were able to communicate without difficulty. The data were collected over an U days period from July 21, to October 14, 1994. The subjects were interviewed using unstructured open questions and the interviews were tape recorded with the patient's permission The data were analyzed using the Van Kaams phenomenological method. Reliability and validity were exammed by two professor of nursing science, one head nurse, one staff nurse and one cardiologist. The results of the study are summarized as follows ; 1. The 129 descriptive statements by the postcardiac catheterization patients of discomfort were organized into 19 themes. 2. The 19 themes were divided into 3 categories ; physical, psychological, and environmental aspects. 3. The problems concerning the physical aspect were the discomfort of restriction of movement, dysuria, medical devices, pain in the puncture site, symptom is related to the procedure of cardiac catheterization, headache and dizziness, leg painand tingling sensation, and chest pain. The problems concerning the psychological aspect were regret resulting from dependency, economic burden, dissatisfaction with medical personnel, dissatisfaction with medical service system, anxiety about the result of the procedure, concern about the prognosis, loneliness, and concern over treatment procedure. The problems concerning the environmental aspect were influence from neighboring patients, noise, and maladaptation to environmental change. The necessity for holistic care which satisfies physical, psychological, and environmental need must be emphasized in order to solve these discomforts.

  • The comparative study of the administration policy that the government and the local self-governing body have enforced to a handicapped child and the family, was made in South Korea and Japan. As data, I utilized brochures distributed to a handicapped child's guardian in the government publication, health center, and hospital of both countries and the homepage that each organization manages. With the investigation of (1) the handicapped child's present condition, population and entering-school situation, (2) the organization which can consult about a juvenile entering-school problem, (3) the public service with which the parents of handicapped child, or a handicapped child are provided and (4) the feedback surveys of (3)’s services, the followings were proved. In (1), the handicapped child's population and their school attendance are not be specified by the South Korea side. In (2), a private consultation organization is mainly opened and be hard to say that use is simple from the little of a kind. In (3), there is almost nothing than rehabilitation education as the administration policy, which is universally held for the handicapped child. Besides they cannot receive freely the education. In (4), it became clear not to carry out. The improvement from the direction of both hard and soft aspects - the institution of basic education for the handicapped child who lives in all areas and the equal opportunity to all children - is called for urgently.

  • This study suggests that some of the negative arguments related to naturalized plants raised in academic discussions are unreasonable through an analysis of trends in the academia's research on naturalized plants in South Korea. A total of 117 academic papers related to "naturalized plants" on the Korean Studies Information Service System (KISS) website were re-classified by space, the number of vascular plant species, the number of naturalized plant species, naturalization index (NI), and urbanization index (UI). Correlation between human interference and naturalized plant distribution, and between sizes of conservation areas and naturalized plant distribution were analyzed. According to the results, while there was a tendency between urban population and UI ($r^2$ = 0.70, p = .000), the number of visitors in national parks had no relation to either the NI or the UI (r = 0.028 and r = 0.013, respectively). Likewise, there was no correlation between national parks or conservation areas and naturalized plant distribution (r = 0.014, r = 0.17, respectively). The average NI and the UI of forest areas were approximately twice as low as those of national parks. In estimated regression equation, when one hypothesizes that the entire 4,952 taxa of plants growing in South Korea, the number of naturalized plants, combining paleo-naturalized plants and neo-naturalized plants, amounted to 2,398 taxa, 48.43%. In the academia, Korean Endemic Plants are less than one quarter of 4,952 taxa. Such results signify that, contrary to discussions in the academia, it is meaningless to distinguish between naturalized plants and native plants. In certain aspects, academic discussions on naturalized plants in Korea have proceeded in a manner similar to cultural exclusion by mono-culturalism in a multi-cultural environment.

  • The purposes of this study were to: a) investigate personal and foodservice operational factors affecting job stress of school foodservice dietitians, b) analyze the contribution of emotional labor to job stress of school foodservice dietitians. A survey was conducted from May 2 to June 13, 2008 to collect data from school foodservice dietitians (N=546). 206 questionnaires were returned completed, and 15 improperly-completed questionnaires were excluded. Finally, 191 questionnaires were used for final statistical analysis (usage rate : 34.98%). The results of the study were as follows. First, personal variables significantly affecting dietitians' job stress were 'monthly bills(p<0.05)' and 'total length of time in school foodservice (p<0.05)'. Second, foodservice operational variables affecting dietitians' job stress were 'school level (p<0.05)', 'type of school foodservice management (p<0.01)', 'number of meal service times (p<0.05)', 'total number of meals served per day (p<0.001)', 'number of meals served per day for students (p<.001)', 'number of meals served per day for teachers (p<0.001)', and 'number of foodservice staff (p<0.001)'. Third, emotional labor was found to contribute significantly to the job stress of dietitians in school foodservice (p<0.001). It was found that as dietitians experience more emotional labor at work, more job stress is experienced. Stress management is a very important and meaningful contributor to foodservice quality as well as to personal well-being for workers in school foodservice. Therefore, it is proposed that management of emotional labor is essential for stress management. Further, emotional labor and job stress should no longer be considered a personal matter, but rather should be approached systematically in all aspects of a school foodservice organization.

  • This study has begun with the perception that proper measuring system is required to grow community business in equilibrium and to grope for some developmental directions of it. First, for effective performance evaluation of community business, the study developed a performance evaluation model based on balanced score cards, and to apply validity analysis and analytic hierarchy process (AHP) by classifying. Second, the relative importance of the second indicator for each of the first aspects shows that participation of local residents and in the aspect of person interested, satisfaction of inner education in the aspect of learning and growth, shortening of work process in the aspect of inner process, and sales per head in the aspect of substantiality were high in relative importance. Third, in the result of calculation of overall weight for each aspect, participation of local residents, a business connection to the community, sales per head were ranked in the upper group. Thus, it's now necessary to have management support through fostering intermediate support organizations in community business which has been bureaucratic, and improvement of product and service through connection with outside consulting agencies and strategic alliance with the leading businesses is required.

  • BACKGROUND: Tetracyclines (TCs) are mainly regulated as parent compounds by bioactivity-based screening methods in food. Especially with respect to antimicrobial residues, their metabolites/epimers are also highly concerning chemicals and traditionally applied microbial detection methods are needed to improve with validation for regulatory control. METHODS AND RESULTS: Detection capability and biological activity of tetracycline (TC), chlortetracycline (CTC), oxytetracycline (OTC) and their epimers; anhydrotetracycline (ATC), epianhydrotetracycline (EATC), epitetracycline (ETC), 4-epi-chlortetracycline (ECTC), 4-epianydrochlotetra-cycline (EACTC), 4-epioxychlortetracycline (EOTC), were measured by microbial growth inhibition screening method of Korea Food Code. CONCLUSION(S): Limited detection capabilities were found, B. megarerium and B. subtilis showed for TC and CTC, and B. subtilis for OTC. Biological potency of each epimer was also presented against various microorganisms, at the level from 50% to 96%, comparing with parent TCs. It is recommended that more advanced microbial screening methods with validation are needed, and biologically active epimers are to be considered as marker residues for MRL setting of regulatory control purpose.
