  • The purpose of this study was to examine the efficiency of senior welfare centers and the cause of differences among senior welfare centers in that regard, and to investigate influential factors for the differences in efficiency and the size of the influence of the factors. What methods would be effective at assessing the efficiency of senior welfare centers by taking into account their circumstances was reviewed, andpost-hoc analyses were made by using data envelopment analysis(DEA) and DAE/AP Modified prosthetic which were useful tools to evaluate relative efficiency. After 20 senior welfare centers located in Gyeonggi-do were selected, their yearly operating data of 2009 were utilized. The purpose of this study was to examine the efficiency of senior welfare centers. The evaluation data released by the Gyeonggi Welfare Foundation were analyzed by DEA, which is one of nonparametric statistics, and it was possible to obtain significant results on the regional operating efficiency of social welfare centers in 14 metropolitan cities and provinces, the causes and degree of their inefficiency and what areas one could refer to. As the data for the counties were utilized in this study, it's not quite possible to produce accurate results on the relative efficiency of senior welfare centers, but this study could be said to be of significance in that it suggested how to evaluate the overall operating efficiency of senior welfare centers in the counties involving the degree of their operating inefficiency, what improvements should be made and what reference groups there might be and provided information on the usefulness of the DEA model.

  • Objectives: Likewise fresh cycle, it is also important to select right blastocysts for transfer in purpose of improving the pregnancy and implantation rates in frozen-thawed embryo transfer (ET) cycles. To investigate the relationship between the developmental velocity at the time of cryopreservation and pregnancy rates, we compared pregnancy rates between the day 5 cryopreservation group and the day 6 cryopreservation group. Methods: Transfers of frozen-thawed blastocysts which had been cryopreserved by vitrification on day 5 or day 6 were performed between January 2006 and June 2007. Ethylene glycol, DMSO, and pull and cut straws were used for vitrification and artificial shrinkage was done in expanded blastocysts. Thawing was performed on the day before transfer and thawed blastocysts were cultured in for 15~18 hrs in Quinn's blastocyct media. Blastocyst survival was assessed before transfer and post-thaw survival was defined as >50% of cells remaining intact and blastocoele re-expansion by the time of transfer. Results: Transfers of thawed blastocyst had been cryopreserved on day 5 were 52 cycles and 41 transfer cycles were cryopreserved on day 6. Patient characteristics, the number of transferred embryos and the survival rate of thawed blastocysts were not different in each cryopreservation day. But the biochemical pregnancy, clinical pregnancy, ongoing pregnancy, and implantation rate were significantly high in transfer of frozen-thawed blastocyst which were cryopreserved on day 5. Conclusions: The clinical pregnancy and implantation rate of day-5 blastocyst showed significantly higher than those of day-6 blastocyst in frozen-ET cycles. This result indicated that developmental rate of blastocyst at cryopreservation time in frozen-thawed cycle is discriminative marker of pregnancy outcome as like in fresh cycle.

  • Purpose: This study was designed to investigate the fitness of adjustable dental impression trays on the Caucasian and African American. Material and methods: The size and shape of these trays were designed from the results of the dental arch size of Korean adults. Tray samples were made by CAD-CAM working. Sixty Caucasian (male:30, female:30) and sixty African American (male:30, female:30) were selected for taking irreversible hydrocolloid impression using these trays. The author measured the width and length of impression material on the several measuring points. Results: 1. Uniform impression material width was achieved by controling the width of the tray using stops and beveled guides. 2. In the maxillary tray on the Caucasian, the impression material thickness was measured to be rather great showing thickness of the midpalatal part 13.0 mm. 3. In the maxillary tray on the African American, the impression material thickness was measured to be rather great showing thickness of the midpalatal part 12.0 mm, posterior palatal part 11.0 mm and the labial frenum width was 11.0 mm. 4. In the maxillary tray on the African American, the impression material width of posterior border (0.8 mm) was measured to be small. 5. In the mandibular tray on the Caucasian, the impression material width was measured (2.7-6.7 mm) and posterior border width (2.1 mm) was measured small. The impression material length was measured (2.8-6.7 mm). 6. In the mandibular tray on the African American, the impression material width was measured to be rather great showing width of the labial frenum 9.2 mm and the width of posterior border was measured too small (0.3 mm). Conclusion: This adjustable dental tray shows good accuracy to Korean because it was designed by the analysis of the dental arch size of Korean adult model. With this result, it can be applied to Caucasian and African American, we can take more easy and accurate dental impressions.

  • Objective: A quality management system of international standardization organization (ISO) 9001:2000 has been proposed to properly evaluate and improve the quality of productions and services. The purpose of this article was to describe on successful introduction and application of the ISO system to human assisted reproductive technology (ART) center. Methods: Center for reproductive medicine and infertility of Cheil General Hospital started the action for ISO 9001:2000 certification at January-2004. The ISO system of our center was monitored by measuring the customer satisfaction index and periodical internal and external audit. Reports of non-conformity described corrective and preventive actions for problems and occurrences that were not consistent with the standard process and operation of our center. Continuous management and improvement were performed on the project of customer dissatisfaction. Results: Our center has got the certification of ISO 9001:2000 for "Research and development of IVF-ET program for infertility treatment" from Korean Foundation for Quality at June-2004. The policy of ISO was "To establish the best center of reproductive medicine and infertility" and "To establish the best quality management system". We found 140 cases and 7 cases of non-conformity in internal and external audit for three years, respectively, and performed corrective action. Conclusion: Improvement of customer satisfaction, systemic documentation and transparency and efficacy of working procedure were achieved by application and operation of the ISO system to our center. This ISO system could be used as a basic institutional management system for the national guideline to the human ART center.

  • This study is an attempt to identify factors affecting korean immigrants concentration in small business enterprises in the middleman minority sector including the priphery and core sectors, with the private wage and self-employed worker examined in each sector, employing the 5 percent public use sample from the 1980 United States census. One out of five koreans aged 25∼64 years is engaged in self-employed small businesses, while the majority of koreans (4 out of 5) are in the private wage sector. In contrast to expectations, English language difficulties and inferior education are not the prime factors affecting self-employment small businesses. The korean self-employed small business owners both in the periphery sector and in the core sector showed the 'middle' strata of their position in the social structure in terms of their industry, occupation, earnings, etc.

  • Purpose: Idoxifene is currently entering phase II clinical trials for the treatment of advanced breast cancer. The radiolabeled idoxifene using $[^{123}I]$ provides an opportunity for clinical pharmacology with single photon emission computed tomography (SPECT). The purpose of this study was to prepare radiolabeled idoxifene using $[^{123}I]$ and to determine its cell uptake of breast cancer cell line. Materials and Methods: With a view to evaluating new anticancer drugs, we are investigating the novel antiestrogen pyrrolidino-4-iodotamoxifen (idoxifene). $[^{123}I]$Idoxifene has been prepared in no-carrier-added form using a tributyl stannylated precursor which has been synthesized by means of (2-chloroethoxy)benzene with (${\pm}$)-2-phenylbutanoic acid on the basis of previously reported standard methods. The biodistribution and dynamic behavior of the compound were investigated using the comparative breast cancer cell line, MCF-7 (estrogen receptor-positive) and MDA-MB-468 (non-estrogen receptor). Results and Conclusion: Acylation of (2-chloroethoxy)benzene with (${\pm}$)-2-phenylbutanoic acid gave the versatile ketone (81%) which reacted with 1,4-diiodobenzene to give triphenylethylene as a mixture of E and Z geometric isomers, which were separated by the recrystallization in ethanol. The E-isomer was treated with pyrrolidine to give idoxifene (67%). In order to incorporate radioactive iodine into the 4-position, the 4-stannylated precursor was prepared (30%). The yield of radioiodination was 90-92% with a high radiochemical purity greater than 98%. The ratio of tumor uptake of the breast cancer cell line between MCF-7 and MDA-MB-468 was about 1.7.

  • The purpose of this study is to use as a basic data of establishing operating Course-based National Technical Qualification(CNTQ) support program by examining the educational needs for operating CNTQ of vocational school teachers, and to contribute to the vocational school settlement of CNTQ course. To achieve those purposes, this study drew 27 tasks performed by teachers operating CNTQ. Also, it surveyed the perceived importance and the performance. The findings of this study are as follows. First, it is showed that 'selection of qualification fields and confirmation of organization criteria, organization of educational training time by competency unit, organization of subjects and establishment of competency unit operating plan by grade and semester, selection of teaching materials, implementation of education and training, establishment of evaluation plan, implementation of evaluation, re-education and re-evaluation students with grades under 40%, guidance of paper evaluation, guidance of practical evaluation, guidance of interview evaluation' are the first priority tasks in the result of the need analysis. Second, it is indicated that 'application of external evaluation, guidance to retake an exam for failure' are the secondary priority tasks. According to these results, the following conclusions were made. First, it will be more positive effects if the educational needs in the next CNTQ support program include contents of the first priority tasks. Second, it is indicated that the priority of the educational needs for tasks of operating plan stages is commonly high. In particular, the highest ranking in the result means that it is completely supported from the first step on operating course. It is expected that the program which teachers on operating the course of similar qualification fields share each operating experience is effective. Third, the priority of the educational needs for external evaluation step ranked high. External evaluation has a different level of difficulty and a form of practical evaluation output according to qualification fields, so the method of guidance has to be different. It needs the program constructed by similar fields.

  • 생물학적 동등성 시험은 동일 성분을 동량 함유한 제제가 유사조건에서 투여되었을 경우 그 유효성분이 전신순환혈이나 작용부위에서 유용하게 되는 속도 및 양에 큰 차이가 없음을 입증하는 시험이다. 즉 이미 제조허가 되어 시판중인 의약품과 동일한 품목의 제조허가를 받기 위한 경우이거나 생체이용률이 동일함을 증명하기 위해 실시하는 시험이다. 우리 나라에서는 1989년 1월 1일 이후 허가된 전문의약품으로서 신약과 동일한 의약품, 패취제제, 제제개선을 통해 흡수율을 높이는 경우에 생물학적 동등성 시험을 하도록 의무화하고 있다. 미국 FDA는 1975년 6월 생체이용률, 생물학적 동등성에 관한 규제안을 발표하였고, 우리 나라에서도 1988년 10월에 생물학적 동등성 시험 기준을 제정하였다. 유럽에서는 1991년 12월 CPMP(Committee for Proprietary Medicinal Products)에 의해 최초로 "생체이용률 및 생물학적 동등성에 대한 가이드라인"이 채택되었다. 그후 전문가 회의를 거쳐 규정 전반에 관한 것과 일반적 항목에 대한 검토가 이루어져 최종 개정된 가이드라인이 만들어졌다. 현재 in vivo 생체 이용률을 비교하는 생물학적 동등성 시험의 중요성이 증대되고 있고, 국제적으로도 각 국가별 생물학적 동등성 시험의 평가방법이나 기준설정에 대한 연구가 다양하게 이루어지고 있다. 또한 ICH에서도 생물학적 동등성 시험의 국제적 조화를 위한 시도가 이루어지고 있다. 우리 나라의 현행 생물학적 동등성 기준은 1998년 개정된 것을 사용하고 있으나 국제적 발전 추세에 맞추어 기준의 제고를 모색하고 있다. 그 일환으로 유럽의 "의약품의 생체이용률 및 생물학적 동등성 시험 가이드라인"을 소개하고자 한다., globunlin II의 두 component로 분리(分離)되었고 oryzenin은 시료(試料) 육우(陸羽) 132호(號), 등판(藤坂) 5호(號), 관산(關山) 재건(再建)에서는 oryzenin I, oryzenin II, oryzenin III의 3 component를 분리(分離)하였고 팔달(八達), 진흥(振興), 서광(瑞光), 은방주(銀坊主), 다마금(多摩錦), Pin Galw56의 6시료(試料)에서는 oryzenin II, oryzenin III의 2 component만 분리(分離)하였다. 3. 각(各) fraction을 여지전기영동(濾紙電氣泳動)하여 각(各) component의 농도곡선(濃度曲線)에 의해 함량(含量)을 구(求)한 결과(結果) albumin 0.26%, globulin I, 0.35%, globulin II, 0.32%, prolamin, 0.41%, oryzenin I, 0.30%, oryzenin II, 2.23%, oryzenin III, 2.66%이었다.미국의 경우 3일 이내 전화나 FAX로 보고하고, 10일이내 문서로써 보고하도록 되어 있다. 이러한 임상적 안전성 자료 관리에 대한 신속 보고 정의 및 기준에 대해서는 ICH에서도 논의가 되어 Step 4까지 다다르고 있으므로 앞으로 각 국에서의 적용만 남아있는 상태이고 보면 신약의 개발과 더불어 임상시험에서의 부작용등의 안전성 자료 관리에 대한 중요성은 더욱 강조될 것이다.공하는 음식의 섭취정도에도 영향을 주고 있으므로 학생들에게 학부모와 전담교사 및 학교영양사는 학생들에게 이상적인 아침식사에 대한 교육은 물론이고 아침식사를 실천할 수 있도록 다양한 방안에 대해 함께 연구해야 하겠다. 정부차원에서 학교급식에 아침식사 프로그램을 도입할
