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.

"學生 體力檢定을 爲한 國家 標準化 評定試案作成에 關한 體育統計學的調査硏究" : 男女 中高等 學生의 體力診斷 測定을 中心으로

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.

이은일,최재욱,염용태,김병헌,김해준 大韓産業醫學會 1997 대한직업환경의학회지 Vol.9 No.4

Sakai's method (1986) has been known as the simplest one for determination of erythrocyte pyrimidine 5' nucleotidase(P5N) activity using high performance liquid chromatography(HPLC). However the drawback of the method is that it is difficult to wash the erythrocyte for isolation. To search for the simpler method, we compared Sakai's method with other methods using whole blood treated with heparin and concanavalin A or whole blood treated with EDTA-2K instead of washing the erythrocyte. The mean concentrations of lead in blood samples collected from 44 male and 16 female workers who are healthy without any exposure to lead in their workplace were 4.30±1.31 ㎍/㎗(mean ±standard deviation), which were measured by frameless atomic absorption spectrophotometer. Erythrocyte P5N activities were measured by 3 methods; Sakai's method(Method Ⅰ), using whole blood treated with heparin and concanavalin A(Method Ⅱ), and using whole blood treated with EDTA-2K(Method Ⅲ). The results were obtained as follows; 1. The mean of erythrocyte P5N activity by Sakai's method(MethodⅠ) were 12.7±2.47 μmole uridine/hr/gm of Hb. 2. The mean of erythrocyte P5N activity by the method using heparinized whole blood treated with concanavalin A(Method Ⅱ) were 13.1,±2.41 μmole uridine/hr/gm of Hb. 3. The difference of mean erythrocyte P5N activity between Method Ⅰ and Method Ⅱwas mot significant. 4. The erythrocyte P5N activity by the method using whole blood treated with EDTA2K(Method Ⅲ) was significantly different from Method Ⅰ. We thought that omission of incubation period which was required on Method Ⅲ using EDTA-2K caused the difference between Method Ⅰ and Method Ⅲ. 5. Simple linear regression equation for erythrocyte P5N activity between Method Ⅰ(Y) and Method Ⅱ(X) was significant: Y= -0.012 +0.9724 X. These results suggest that the method using whole blood treated with heparin and concanavalin A is simpler to examine the erythrocyte P5N activity as a biological indicator of lead intoxication than Sakai's method.

Objectives : The purpose of this study was to investigate whether elderly and young adults differ in their recognition of facial expressions of emotion. Methods : A total of 120 (elderly group 53, young group 67) subjects participated in this study. Korean facial expressions of emotion including happiness, sadness, fear, anger, disgust, surprise and neutral were used as stimuli for facial affect recognition test. Computerized facial affect recognition test that consists of facial affect discrimination test and facial affect intensity test was performed. Results : For facial affect discrimination test, there was a significant difference between two groups (F==3.986, P<.01) after controlling the effect of education. Elderly participants showed significantly less correct recognition rate with sadness, anger and disgust (p<.05). For facial affect intensity test, there was no significant difference between the groups in recognition of emotional intensity. Chi-square test or t-test was done according to the clinical variables. Multivariate analysis of covahance was done to test group differences of correct recognition rate and emotional intensity. Conclusion : This is the first report of differential decrease of facial affect recognition in elderly using Korean facial expressions. This study suggests that the decrement of facial affect recognition maye be a part of normal aging process.

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.
