Ovarian pregnancy is an uncommon form of the ectopic pregnancies. The ovarian vascularity results in maternal hemorrhage early in the first trimester, which disrupts the pregnancy and usually ruptures the ovary with sufficient hemoperitoneum to require emergency operation. This report presents 10 cases of ovarian pregnancy by retrospective review between January 1986 and December 1995 at the Department of Obstetrics and Gynecology, Soonchunhyang University Hospital. There was 19,849 deliveries and 637 ectopic pregnancies during same period. It showed that the incidence of ovarian pregnancy was 3.21 % of all ectopic pregnancies. The clinical features of ovarian pregnancy revealed that abdominal pain was the major symptom, and history of amenorrhea was obscure. Because of life-threatening course, the early diagnosis and treatment of ovarian pregnancy is important. The clinical diagnosis of ovarian pregnancy was more difficult than that of tubal pregnancy.

Ho-Chang Lee1, Seung-Myoung Son, Yong-Moon Lee, Ji Hae Koo, Song-Yi Choi, Ok-Jun Lee, Eun-Hwan Jeong 충북대학교 동물의학연구소 2012 Journal of Biomedical and Translational Research Vol.13 No.2

Malignant transformation of mature cystic teratoma (MCT) is rare. Sarcomatoid carcinoma is a neoplasm comprising malignant mesenchymal cells and a conventional carcinomatous area. Here, we report on a case of sarcomatoid carcinoma arising from an MCT in the left ovary of a 45-year-old female. A unilocular cyst consistent with MCT was observed; however, a nodule within the cyst was confirmed from the resected ovary. Microscopically, the nodule showed both squamous cell carcinoma and pleomorphic sarcomatous components admixing with each other. Lining epithelial cells at the periphery of the main tumor showed squamous metaplasia. When a sarcomatous component is observed in the ovary tumor, it is important to find a squamous cell component, either benign or malignant.

Background : Gastric cancer is the most common malignant tumor in Korea. surgical operation is one of the major treatment modalities for gastric cancer patients. Therefore, gastrectomy is one of the most common procedures in General Surgery. There were variation in length of hospital stay and medical treatment for gastrectomy between three surgeons at Asan Medical Center. Clinical pathways have received considerable attention as a tool for recucing the medical practice variation, increasing the efficiency of care process, and improving the quality of care. The aim of this study was to evaluate the effect of a clinical pathway for gastrectomy in gastric cancer patients. Methods : The clinical pathway for gastrectomy was developed and implemented by a multidisciplinary group in Asan Medical Center. A computerized clinical pathway program was developed and revised after a pilot test. A total of 145 patients underwent gastrectomy by three surgeons at Asan Medical Center. We compared the length of hospital stay, patient satisfaction, and unplanned readmission rate between the pre-pathway group(n=67) and the post-pathway group(n=78). We also investigated the degree of satisfaction among the physicians and nurses who were main end-users of the clinical pathway. Results : The clinical pathway was applied to all target patients. The average length of hospital stay was shortened from 12.7days to 10.6days(p<0.01). The degree of patient satisfaction with the care process changed from 90.3% to 89.2% after the implementation of the clinical pathway, but the difference was of satistically significant(p=0.761). Unplanned readmission rate was 2.9% in the pre-pathway group. More than 90% of physicians and nurses answered that the clinical pathway had been a useful tool in their medical practice. Conclusions : The findings of the study demonstrated that implementation of the clinical pathway for gastrectomy produced substantial reduction in the length of hospital stay while improving the quality of patient outcomes. The computerized clinical pathway program can be used as one of the powerful patient management tools for reducing the practice variations and increasing the efficiency of care process in Korea hospital settings.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

이한용,유기원,정진영,송주현,고해석,강용구,손문익 대한골절학회 2003 대한골절학회지 Vol.16 No.2

주관절 손산 중 상완골 내 상과 골절은 단독으로 혹은 주관절 탈구와 동반되어 발생하는 것이 일반적이다. 저자들은 15세 남자 환자의 좌측 요골 두 아탈구가 동반된 상완골 내 상과 골절을 경험하였다. 도수 정복을 시도하였으나 요골 두 아탈구의 정복을 얻을 수 없어 관혈적 정복술로 치료하엿다. 6개월추시 결과 후휴증이 없는 정상적인 관절 상태를 확인할 수 있었다. 연령, 원인 , 손상 기전으로 분석해 보면 이 동반 손상은 발생하기 매우 어렵고, 문헌 탐색 결과 현재까지 동일한 증례를 찾아볼 수 없었으므로 보고하는 바이다. It has been known that fracture of medial epicondylar apophysis of distal humerus may be isolated of associated with elbow deslocations. We have experienced a case which medial epicondylar fracture of the distal humerus was associated with subluxation of the radial head. Initially, we had tried reduction of subluxated radial head by closed method, but failed. Finally open reduction gad been performed. At 6 month after open reduction, clinical and radiological result were excellent. As it is difficult for those associated injuries to occur simultaneously and the similar cases never have been reported yet, we would like to present this case with a review of the literature.

李海容,趙顯麒 慶北大學校 産業開發硏究所 1985 硏究報告 Vol.13 No.-

The age-precipitation during recrystallization of supersaturated cold-deformed Al-Mn alloy has been investigated by means of measurements of microvickers hardness, electrical resistivity and transmission electron microscopy. The results obtained are summarized as follows 1. Increasing Mn contents, precipitation rate in the range below the recrystallization temperature was accelerated and recrystallization temperature increased. 2. In the range below the recrystallization temperature, most of precipitation was progressed before recrystallization and in the range above the recrystallization temperature, most of precipitation was progressed after recrystallization. 3. Precipitated phases were Al_6Mn phases at all examined temperatures and precipitation hardening was negligibly small.

이광영,변주현,송혜란,김진하,고광욱,이용환 大韓産業醫學會 2003 대한직업환경의학회지 Vol.15 No.2

목적: 본 연구는 여름과 겨울의 계절적 차이에 따른 디메틸포름아미드의 체내 흡수의 변화를 알아보고자 시행되었다. 방법: 일개 합성피혁제조업체에서 직접적으로 디메틸포름아미드를 취급하는 22명의 근로자들을 대상으로 2001년 2월(겨울)과 7월(여름)에 작업환경측정을 통해 기중 DMF농도를 측정하였고 특수건강검진을 실시하여 요중 NMF의 배설량을 측정하고 간기능 검사를 시행하였다. 또한 검사 당일의 평균 기온과 평균 습도를 측정하고 설문지를 통해 알코올 음주 정도, 피부 질환의 유무, 보호구 착용 유무 등을 조사한 후 여름과 겨울의 자료를 비교 분석하였다. 결과: 겨울과 여름의 평균 공기 중의 디메틸포름아미드 기하 평균 농도는 각각 11.55ppm, 13.78ppm으로 통계적으로 유의한 차이는 없었으나 요중엔-메틸포름아미드 배설량의 기하 평균은 겨울이 31.23㎎/g creatinine인 것에 비해 여름이 96.09㎎/g creatinine으로 겨울에 비해 여름의 요중 엔-메틸포름아미드 배설량이 유의하게 높았다(p<0.05). 공기 중 디메틸포름아미드 농도(ppm)에 대한 요중 엔-메틸포름아미드 배설량 (㎎/g creatinine)의 비는 여름(1:6.97)이 겨울(1:2.70)에 비해 약 2.6배 정도 높았다. 결론: 여름과 겨울의 요중 NMF배설량의 차이는 아마도 연구 대상 사업장의 환기 시설이 미약하고 근로자들이 DMF에 적합한 보호구를 적절하게 사용하지도 않았기 때문이고, 무엇보다도 높은 온도와 습도에서 짧은 옷을 입고 근무함으로써 피부 노출면적이 증가되어 DMF의 피부 흡수의 양이 많아졌기 때문으로 판단된다. Objectives: This study was carried out to identify seasonal variations of urinary concentrations of N-methylformamide(NMF) among workers employed at a synthetic leather factory. Methods: Study subjects consisted of 16 male and 6 female workers who were involved in the direct treatment of dimethylformamide(DMF) in a synthetic leather factory. By using health examination data and the results of air measurements and biologic monitoring conducted in February and July, 2001, we identified seasonal variations of the DMF concentrations in the air and NMF concentrations in urine. Results: 1) In winter and summer, average temperatures at the working sites were 3.2℃ and 26.5℃, respectively and average humidities were 35.4% and 84.5%, respectively. 2)Airborne DMF concentrations were not significantly different between summer(13.78ppm) and winter(11.55ppm). 3)NMF concentrations in urine were found to be significantly higher in summer(96.09㎎/g creatinine) than in winter(31.23㎎/g creatinine) (p<0.001). Conclusions: The seasonal difference in the urinary excretion values of NMF may be due to increased dermal absorption of DMF with the higher ambient temperature and humidity in summer and the increased area of exposed skin.

李龍海 군산교육대학 1970 論文集 Vol.3 No.-

I. INTRODUCTION In order to accomplish the development and modernization of our country, we have to help children grow up healthy and strong. But at present,there are many problems which we have to improve in the bodily development of our children. One of these problems is that it seems our children's physical strength is more under-developed than that of other countries' children. Thereupon, in the earlier study I have attempted to examine ways of improving and managing physical education by formulating the elementary school students' physical strength measurement in 1968. I have set forth the results of it and rep-orted it to the Ministry of Education in February,1969. In the present study,I have attempted to examine ways of improving and mana-ging physical education, and formulating national standardized rating criteria for secondary school students' physical strength measurement continually in 1969. I have shown the results for the purpose of reporting it to the Ministry of Education. The study is based on random samples of 1,800 secondary school boys and girls, covering Kunsan City as an urban community Kim Je Up and Jung Joo Up as a rural community and Go Chang Gun as remote mountain community in Jeoullab-ugdo.The research is performed by the survey to discover the problems of lower physical strength of students and for diagnosing and valuating basic physical strength and basic motor skills. The standardized rating criteria table of the physical strength is made by the method of standard deviation and the method of percentile. There are eight items of physical strength measurement,such as agility,muscular power, muscular stren-gth, softness, balance, and endurance of boys and girls equally. There are six items of the fundamental motor skills test, such as running, jumping, throwing, pull-up, and co-ordination. The result of the fundamental physical strength diagnostic test is standardized by calculating the score of each item at five and the total score at 40 and by rating the score with the method of standard deviation. The result of the funda-mental motor skills test is standardized by calculating the score of each item at 20 and the total score 100 (Two items of co-ordinating strength are calculated as one item.) and by rating the score with the method of percentile, and the gener-alized result of the examination of the classtfied dedision table is formulated by sex and age, respectively. The research of the elements of lower physical strength is observed by the survey concerning the elements of nutrition, environment, physical activities and facilities of physical education. II. RESULTS OF THE RESEARCH A. The results of the fundamental physical strength measurement may be summarized as follows : (1) The scores of boy students' fundamental physical strength are a little higher than those of girl students. (2) According to the comparison by regional groups, the rank of the boy students' fundamental physical strength score is decided as follows : The highest regi-onal group is the urban community, the second the rural community, and the third the remote mountain community. The rank of the gril students' fundam-ental physical strength score is decided as follows : The highest regional group is the remote mountain community, the second the urban community, and the third the rural community. (3) According to the generalized progression of judgement, both boy students and girl students are "C" grade equally, and 48% of the boys and 44.7% of the girls are "C" grade. B. The results of the fundamental motor skills test may be summarized as follows : (1) The scores of boy students are a little higher than those of girl students. (2) According to age comarison by regional groups, the rank of the scores of boy students' fundamental motor skills test is decided as follows : The highest regional group is the urban community, the second the rural community, and the third the remote mountain community. The rank of the scores of girl students is decided as follows : The highest regional group is the remote moun-tain community, the second the rural community, and the third the urban community. (3) The ranks of the generalized progression of judgement of the fundamental motor skills are decided five,four, three, two, one and zero. According to the result of students' fundamental motor skills test, the highest frequency is five, the second three, the third four, the fourth two, the fifth one, and the last zero. A percentage of 28.6 of the boy students, and 38.0 of the girl students made the highest score. (4) The score of our students fundamental motor skills is lower than that of Japanese students. III. CONCLUSION As the above statements show, there are many problems both is secondary school students' fundamental physical strength and in their fundamental motor skills. In the following, I am going to suggest methods of overcoming those problems. (1) We have to improve the diet to supply enough nutritious food. (2) We have to improve the life environment for the students to grow up healthy and strong. (3) We have to improve the method of physical education in secondary education. (4) We have to establish enough facilities for physical educatian. (5) We have to perform both the subject matter and guidance services for improving physical education. In the following, I would like to acknowledge my indebtedness to many people who have helped me make this work possible. First I would like to express my gratitude to the authorities of the Ministry of Education who supplied the reseach expenses. I would also like to acknowledge my gratitude to the superintendent of Jeoullabogdo Board of Education, the supervisor of physical education, principals, and teachers who helped me. And I would also wish to express sincere thanks to the director of Kunsan Teachers' College.

소프트웨어는 갈수록 대규모화, 다기능화되는 방향으로 발전하고 있다. 더불어 소프트웨어에 관한 사용자의 요구 수준도 높아지고 있으며 특히 소프트웨어의 품질에 대한 요구는 지속적으로 높아지고 있다. 이러한 사용자의 요구를 만족시킬 수 있는 방안들이 다양한 관점에서 연구되고 있다. 그중에서도 소프트웨어의 품질평가를 통해 그 결과를 개발자에게 피드백함으로써 소프트웨어의 품질을 향상시키려는 관점에서 품질평가 체계 및 방법론에 대한 연구가 활발히 진행되고 있다. 본 논문에서는 소프트웨어의 품질에 관한 국제표준인 ISO/IEC 9126의 품질특성 중 신뢰성에 대한 품질특성, 부특성, 내부특성의 체계에 따른 메트릭스와 품질측정표를 개발함으로써 관련 내부특성의 품질평가를 통해 신뢰성에 대한 평가 결과를 산출할 수 있는 체계를 확립하고 개발산출물에 대해 평가한 결과를 제시하였다. α,ω-Bis[Co₂(CO)6{μ-η²:η²-C(R)≡C}]oligothiophene derivatives (6-10), in which two dicobalt hexacarbonyl acetylides are π-conjugated onto both terminals of the oligothiophene, were prepared by the reaction of the α,ω-bis(alkynyl)oligothiophenes (1-5) with Co₂(CO)8. The molecular structures of new compounds were identified by spectroscopic methods and elemental analysis. In cyclic voltammetry of the clusters 6-10, two oligothiophene-based oxidation processes (one for 7) occur between - 0.2 and 1.5 V, and the one reductive process of the metal cluster moieties occurs between 0.0 and - 1.6 V, which is not present for the oligothiophenes (1-5). The silence of the expected electronic communication of the clusters 6-10 may be attributed to the reduction process followed by fast chemical reactions at ambient temperature. The clusters 6-10 commonly exhibit three characteristic bands: a moderately intense, high-energy band, strong medium-energy band and weak-low energy band. The high-energy bands are attributed to the a π-π localized excitation. The medium- and low-energy bands may be ascribed to the metal-to-ligand (d□-π□) charge-transfer transitions of the cluster moiety.
