This study aims to evaluate a porous concrete using hwang-toh, blast furnace slag and blast furnace slag (BFS) cement instead of type I cement. The tests that were carried out to analysis the properties of porous hwang-toh BFS cement concrete included compressive strength, continuous void ratio, absorption rate, and pH value, repeated freezing and thawing test were conducted. Test results indicated that the performance in porous hwang-toh concrete are effective on the kaoline based binder materials. The pH value were shown in about 9.5 ~ 8.5. The compressive strength was increased and void ratio was decreased with increasing the kaoline based binder materials, respectively. The void ratio and compressive strength were in the range of about 21 ~ 30 %, 8 ~ 13 MPa, respectively. The increased in void ratio of more than 25 % is showed to reduce the resistance of repeated freezing and thawing. Also, the resistance of repeated freezing of thawing and the compressive strength of porous hwang-toh BFS cement concrete are independent with hwang-toh content and BFS cement amount. But, the void ratio was decreased with increasing the high volume hwang-toh contents (more than 15 %).

연구목적: 유전이 정신분열병의 중요한 원인이라는 것은 널리 인정되어 왔다. 본 연구는 한국인 정신분열병과HLA-DRB1 유전자좌와의 관련성을 알아보고 외국인 대상의 보고들과 비교함으로써 한국인 정신분열병의 유전적 특성을 밝히고자 시행하였다. 방법: 정신분열병 환자 70명을 대상으로 HLA-DRB1 대립유전자를 고해상도 수준까지 분석하였다. 저해상도 수준의 HLA-DR결과는 정상 한국인 2,000명의 연구 보고와 비교하였으며 고해상도 수준의 HLA-DRB1 결과는 정상 한국인 229명의 연구 보고와 비교하였다. 결과: 저해상도 수준에서는 HLA-DR11이 정신분열병 환자군에서 9.0%, 정산인에서는 3.8%의 빈도를 보여 환자군에서 통계적으로 유의하게 높은 빈도를 보였으며(p=0.005), 고해상도 수준에서는 HLA-DRB1*1101이 환자군에서 9.0%로 정상인의 1.8%보다 유의하게 높은 빈도를 보였다(p<0.001). 결론: 본 연구에서는 한국인 정신분열병과 HLA-DR11(HLA-DRB1*1101)이 양적 상관관계를 보여 백인에서 DR4와 부정적 상관관계를 보인 결과나 일본인에서 DR1(DRB1*0101)과 양적 상관관계를 보인 결과와 상이하였다. 이러한 한국인 정신분열병 환자의 유전적 특성은 가족연구 혹은 더 많은 수의 환자를 대상으로 한 관련연구를 통하여 재확인되어야 할 것이다. 중심단어:정신분열병·HLA-DRB1·관련연구. Objective: A genetic predisposition is widely accepted in schizophrenia. This study was intended to fine any association of HLA-DRB1 alleles with korean schizophrenics and thereby compare the results of other ethni groups. Method: The subjects were 70 unrelated Korean patients. Low and high resolution typing of HLA-DRB1 alleles were performed. The comparison groups were 2,000 unrelated healthy Koreans for low resolution HLA-DR and 229 unrelated healthy Koreans for HLA-DRB1 alleles. Results: Gene frequencies of HLA-DR11(patients 9.0%, healthy control 3.8%, p=0.005) and HLA-DRB1*1101(patients 9.0%, healthy control 1.8%, p<0.001) were significantly higher in Korean schizophrenics. Conclusion: The frequency of HLA-DR11(HLA-DRB1*1101) is significantly higher in Korean schizophrenics than in healthy Koreans. HLA-DR4 and HLA-DR1, which were known to be associated with Caucasian and Japanese schizophrenics, respectively, did not show statistical association with Korean schizophrenics. This association need to be reassured though further studies with families or association study with larger numbers of subjects. KEY WORDS:Schizophrenia·HLA-DRB1·Association study.

Vesicovaginal fistula is a distressing complication which may follow hysterectomy, prolonged labor, chemical cauterization due to uterine prolapse, radiation therapy and cervix cancer. The management of vesicovaginal fistula still remains controversial in regard to the type of approach and timing of repair but the classic opinion is to wait 3 to 6 months to allow the surgical inflammatory reaction to subside. We experienced 4 cases of vesicovaginal fistula which were as follows; Case 1: 51-year-old The vesicovaginal fistula, about 3.0cm in diameter, after laparascopic hysterectomy 15 days ago was repaired with interposition of a gracilis muscle flap via the transvaginal route. Case 2: 38-year-old The vesicovagianl fistula, about 2.5cm in diameter, after Cesarean section 5 years ago was repaired with interposition of the omental flap via the transabdominal route because she had been accompanied by an overian cyst. Case 3: 46-year-old The vesicovaginal fistula, about 2.5cm in diameter, after manual self abortion at home 30 years ago was repaired with interposition of fibro-fatty tissue in labia via the transvaginal route. Case 4: 43-year-old The vesicovaginal fistula, about 2.0cm in diameter, after prolonged labor 12 years ago was repaired with interposition of the fibro-fatty tissue in labia via the transvaginal route. There noted no complications or recurrence during the minimal 1 year follow-up.

The actual state of using, purchasing of combines have been investigated among the farmers who possess the three row and four row type combines of self thresher in Chung-Nam Province to present reasonable maintenance and utilization of combines. And then the condensed results are as follows. 1. It was found that 25.9% of surveyed farmhouses cultivated rice over 4.5ha which brings average income presented by the Department of Agriculture and Forestry. And 85.2% of farm houses had higher income than the national average 23,488,000 won in 1997. 2. It was surveyed that the working hours a day and working days a year are 9.26 hours and 19.2 days. And they have the charge of 22.8ha a year. 3. It was shown that the most frequent breakdowns happened to pretreating and reaping in 44.4% and the frequency of the annual repair and maintenance is 4.1 times. And they think the endurance years of 6.5 is proper. 4. It was surveyed that 33.3% of the farmers were motivated to buy combines for their own management and supporting others, 22.2% for the difficulties of timing, 9.3% of them for the possibility of purchasing in cheap price. 5. It was found that when they decided to buy combines, 61.1% of farm houses had experiences of analyzing for their management and 38.9% of them didn't. Also the more combines they purchase, the larger and higher qualities of combines they tend to choose. 6. It was shown that 25.9% of surveyed farmers were satisfied with their combines and 74.1% of them weren't. 47.5% of dissatisfaction resulted from high price, 27.5% from frequent breakdowns, 12.5% from rough after service. 7. I think it is necessary for the related authorities to give public information and education for maintenance, management analysis, keeping of combines to make farmers purchase and use them reasonably. Also overall supporting policies are needed for research and development of highly efficient combines and the ways of securing cultivating areas with the spread of large size combines.

Objectives : There is a increasing need to recruit and retain more psychiatrists who can plan and implement organized programs to work with chronic mentally ill patients in community settings. The aim of study is to discover what training is currently in place to prepare psychiatrist for work in "community" or "public" settings. Methods : Survey questionnaires were mailed to 85 residency training directors and 10 leaders of community mental health in 2005. Response rate was 75%. Results : Academic seminar about community mental health were not administered to residents in 63% of training hospitals. Forty one out of 64 training hospitals had community mental health rotation programs, Community mental health center (50%) and day hospital (36%) were the most common type of programs. Few general hospital had affiliation with community mental health programs. The amount of time for clinical rotation varied from less than three months part time to 6 months fulltime, with most frequent form of one day per week for three month in second or third year of psychiatry residents. Conclusion : Further steps are needed to improve residency training curricula and to encourage well qualified psychiatrist to choose careers in community psychiatry.

The purpose of this study was t.o assess the efficacy of several thermal therapies using ice pack, moist-hot pack and ultrasound, separately and concomitantly and to obtain the background information on the vascular changes after thermophysical therapies. The author had used 15 healthy subjects were examined and the subjects were divided into 5 groups; ice pack, moist-hot pack, ultrasound, ice pack and moist-hot pack, ice pack and ultrasound. Observation were made immediate before and 0, 5, 10, 20, 30, 45, 60, 90 minutes after treatment. Thermography was performed in an Agema 870 thermovision with 0.1°C difference of gradual temperature shift, The results were as 'follows 1. Using ice pack only, the surface temperature of the masseter region was increased lapse of time, and most remarkably 90 minutes after the treatment. 2. Using moist-hot pack only, the surface temperature of the region was remarkably increased immediately after the treatment, but decreased lapse of time. 3. Using moist-hot pack with ice pack, the surface temperature of the face was remarkably increased immediately after the treatment, and decreased lapse of time. Hyperthermia was maintained for a longer time as compared with the group of moist-hot pack only. 4. Using ultrasound only, the surface temperature of the region was increased gradually, and most remarkably 30 minutes after the treatment, but decreased in the course of time. 5. Using ultrasound combined with ice pack, the surface temperature of the region was gradually decreased until 30 minutes after the treatment, and decrease to some extend at 45 minute And then a gradual increase observed over the remaining period of the experiment. 6. Hyperthermia were maintained for a longer time in the groups using ice pack combined with moist-hot pack and ultrasound as compared with the other groups. Our data suggest that ice pack can promote the efficacy of other thermal therapies.

Patients with ureteral calculi may be managed by expectant, invasive, or noninvasive treatments, depending on the stone composition, size and location, expectations of the patients, and experience of the surgeon. Currently ureteroscopic removal of stone(URS) has been popularly used for the treatment of ureteral calculi. From January 1992 to December 1994,we retrospectively compared the clinical results of 87 URS's to those of 31 ureterolithotomies and analysed the factors that affect the result of URS. The clinical results of two groups were summarized as follows The mean stone size was 7.6㎜ in URS group and 12.1㎜ in ureterolithotomy group. In 81.6% of URS group, the stone was located in the lower ureter and 71% of ureterolithotomy group in the upper ureter. The mean operation time, hospital stay and costs of the URS group, 96.6% of the stone were removed or disintegrated. There was no statistical significance in the success rate of URS along the sex difference, the location and size of stone. However, the higher the location of stone was, the more operation time spent. The complication rate of URS was estimated 26.5% but most of complications were resolved by conservative management. We conclusively suggest that the URS is the acceptable alternative modality of the ureterolithotomy for the treatment of the ureteral calculi.

유홍식,황선진 服飾文化學會 2003 服飾文化硏究 Vol.11 No.6

The purpose of this study is to analyze how the women's fashion with the androgynous image(fashion item, adornment) which has appeared on our specialized fashion magazine from 1986 through 2000. As a result of this study I drew the following conclusion. First, masculine image led the market in the first stage of mid 1980 in a men's wear oriented trend that the woman wear masculine style jacket, pants and blouse. In hair style, the short hair of the masculine image was used habitually but the make-up was tend to be made heavily. The ambivalence of the sex was also showed up by expressing the feminine image on the masculine image using the accessories like necklace, earing and bracelet. Second, unlike the first stage, it showed that more and more feminine image was accepted in the second stage of early 1990. The jacket, blouse and pants were rooted as the basic item in women's fashion. The feminine style of long hair and natural make-up with the and androgynous image were increased. Third, in the third stage of the late 1990, the fashion items to the comfortable dress of light weight as the life style pursuits the activity and convenience. The feminine image were appeared naturally with a long hair style and natural make-up with the androgynous image. The remarkable features in the fashion accessories were that boots and low shoes were preferred by the increase of the masculine image shoes and the sneakers were seen a lot by the effect of the sports boom.
