The physical, mechanical, water purification and temperature properties of fiber reinforced porous hwang-toh green roof concrete have been evaluated in this study. The effect of the depending on replacement ratio of blast furnace slag to cement was investigated such that the replacement ratio is varied to 0 % and 30 %. Also, the replacement ratios of hwang-toh were 0, 20 and 30 %. The polyvinyl alcohol fiber was used for the reinforcing fiber. A series of pH test, unit weight, void ratio, compressive strength, after purification and variation of temperature test have been performed to evaluate the performance, water purification effect and temperature properties of the fiber reinforced porous hwang-toh green roof concrete. The test results indicate that the physical and mechanical properties of fiber reinforced porous hwang-toh green roof concrete is affected by the replacement ratio of the blast furnace slag and hwang-toh contents. Results of purifying water showed that the water purification effect of porous hwang-toh green roof concrete is about 40 %. Also, the temperature properties test results indicate the green roof blocks using fiber reinforced porous hwang-toh green roof concrete have insulation and temperature reduction effect.

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 %).

Collecting duct renal cell carcinoma (CDRCC) or Bellini duct carcinoma is a rare type of renal cell carcinoma (RCC), accounting for 0.4% to 1.8% of all RCC. CDRCC is considered to originate from the collecting duct of the kidney and it has a poor prognosis. However, the clinical features of CDRCC remain poorly understood, mainly because only studies with a small series or case reports have been published to date. We experienced a case of CDRCC of kidney.

Dictyostelium monochasioides was the most frequently found in Pinus community, but D. polycephalum was the most frequently found in Quercus community. Dictyostelium polycephalum and Acrasis rosea were more occurred in Quercus variabilis than in Pinus rigida, but D. purpureum, D. septentrionalis, Acytostelium sp., P. mexicanum, P. pallidum, P. filamentosum and Gutitulinopsis sp. were more occurred in community of Pinus rigida than in Quercus variabilis. The average number of species isolated from community of Pinus rigide was 12.25, but isolated from commuity of Quercus variabilis was 8.88.

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.

Purpose: The purpose of this study was to investigate the relationship between teaching effectiveness and clinical practice satisfaction among nursing students. Method: The subjects of this study were 107 junior and senior nursing students in E university. Data were collected using self-reported questionnaire including general and practicum related characteristics, teaching effectiveness of clinical instructors and clinical practice satisfaction from September 12 to September 21, 2011. Collected data were analyzed by SPSS 19 program using t-test, ANOVA with Scheffe test, and Pearson`s correlation coefficients. Result: The mean score of teaching effectiveness was 3.35(±.51), and mean of clinical practice satisfaction was 3.19±.47. There were significant differences of teaching effectiveness of clinical instrutor by satisfaction of overall clinical practicum(F=8.332, p<.001), satisfaction of practice hour(F=3.230, p=.044), and satisfaction of major(F=9.883, p<.001). There were significant differences of clinical practice satisfaction by grade(t=2.274, p=.025), motive of choosing nursing science as a major(F=3.329, p=.007), satisfaction of overall clinical practicum(F=17.437, p<.001), satisfaction of practice hours(F=9.925, p<.001), and satisfaction of nursing major(F=12.748, p<.001). Relationship between teaching effectiveness of clinical instructor and clinical practice satisfaction showed positive correlation(r=.704, p<.001). Conclusion: In this study, teaching effectiveness of clinical instructor was related with clinical practice satisfaction. Therefore, we should consider improving teaching effectiveness of clinical instructor to improve clinical practice satisfaction.

We traced the flow direction of Ipbong Andesite and dacite in Dalsan area, Yeongdeok. Elongate vesicles and lathlike plagioclase phenocysts are aligned in the outcrops or under microscope. The lineations from their alignment are excellently indicating the flow direction of lavas. The flow directions, which were measured from the lineations in the Ipbong Andesite, are NNW-SSE in the eastern part and NNE-SSW in the southwestern part. The flow lineations show a fanlike movement pattern from the mid-northern part that the diorite is distributed. The diorite area is prabably a potential source area of the andesite
