Objectives : Diffusion tensor imaging (DTI) is a new technique that can be used to visualize and measure the diffusion of water in brain tissue. It is particularly useful for evaluating white matter abnormalities. In this paper, we investigated the neuropathology of the corpus callosum in patients with schizophrenia through the new methods, diffusion tensor imaging. Methods : Diffuse tensor imaging was performed in 19 schizophrenic patients and 26 healthy controls. One complementary measure, fractional anisotropy (FA), which is considered to be sensitive indices of axonal integrity, was obtained from regions of interest in the five areas of the corpus callosum. Neuropsychological measurement also underwent for measurement of frontal lobe function in two groups. Results : There were no significant differences of FA in the DTI measures for either the schizophrenic patients compared with controls. FA was significantly decreased in women compared with men. Neuropsychological measurements such as Wisconsin card sorting test were correlated with FA of patients with schizophrenia. Conclusion : FA measures revealed no differences between schizophrenia and controls. The findings suggest that the structural integrity of white matter in patient with schizophrenia was not disrupted. The results are discussed in relation to previous studies reporting positive and negative findings. It is concluded that further studies using DTI in larger samples, improved and standardized methods of data acquisition and analysis are needed.

늦가을과 초본 사이 제주도 후면에 Karman vortex street가 발생한다. 이러한 vortex가 발생하기 위해서는 기온 역전층과 5 ~ 13 m/s의 지속적인 바람이 필요하다는 것을 밝히기 위한 많은 연구들이 있었다. 이러한 vortex clouds는 발생 후 주 풍향의 방향을 이동하게 된다. Karman vortex street는 기상학에서 매우 흥미로운 주제이다. 본 연구에서는 LES 난류 모델을 이용하여 Karman vortex street에 관한 해석을 수행하고 수치해석을 통해 얻은 결과와 기상 데이터가 일치함을 보였다. From late autumn to the beginning of the spring, the phenomena of the Karman vortex street have been frequently observed in the wake of Mt. Halla in the Jeju island. Some researches revealed that the necessary conditions for development of these vortex clouds are a strong low-level inversion of temperature and a persistent wind speed of 5 to 13m/s. After the cloud is formed, the vortex clouds are shed from alternating sides of Jeju island and then move downwind with main airflow stream. The Karman vortex street in the wake of the Jeju island was one of the interesting topics in meteorology. In this study, CFD using LES turbulence model was developed to investigate the Karman vortex street and the results of CFD showed a good agreement with weather data.

( Sook Kyung Lee ),( Taek Geun Lee ),( Hyun Hwang Bo ),( Tae Gwang Kwon ),( Se Won Jung ),( Young Seok Lee ) 대한피부과학회 2013 대한피부과학회 학술발표대회집 Vol.65 No.2

Background: Complementary and alternative medicine (CAM) is any practice that has healing effects, but is not based on evidence demonstrated by scientific method. Recently, CAM has been used in various diseases including acne. However, there have been no studies on CAM for acne in Korea. Objectives: The purpose of this study was to analyze the use of CAM in acne patients. Methods: A total of 159 patients with acne were enrolled on the study, and filled out a questionnaire about use of CAM. Results: Overall 87.4% (139/159) of the patients reported the previous or current use of at least one more type of CAM. Cosmetics for acne (100, 22.9%) was most frequently used, followed by diet therapy (81, 18.5%), spa and bath therapies (77, 17.6%), health food supplement (67, 15.3%), skin care shop (64, 14.6%), oriental medicine (38, 8.7%), and aromatherapy (9, 2.1%). The most common reason for using CAM was ``wish to try everything`` (28.6%), and the most common source of information was internet (40.5%). The therapeutic effect of CAM was best with diet therapy (32.1%). The most common side effect of CAM was aggravation of symptoms. The most common monthly cost for CAM was between 50,000 and 100,000 won/person. Conclusion: As our results, we can predict that the use of various types of CAM for acne will become more common. Therefore, dermatologists need to study about benefits and adverse effects of CAM for acne.

This paper aims at providing a concrete plan to improve technical and vocational teacher education in the College of Industrial Education of Chungnam National University. It is intended to propose a practical four-year regular and short-term course. Also, the estimated required facilities is included in this study as well as their management. The main conclusions and recommendations are summarized as follows; 1) The numbers of students enrollment should be reduced to 220 students which is the approximate number of future demand. 2) In order to offer to the students a broader education and to cope with the increase/decrease in demand of technical and vocational teacher within a specific field, the 8 department existing at the present (Department of Architecture Engineering Education, Civil Eng. Educ., Metallurgical Eng. Educ., Mechanical Eng. .Educ., Electrical Eng. Educ., Electronic Eng. Educ., Industrial Chemistry Educ. and Industrial Technology Educ.) would be combined into 5 (Department of Construction Engineering Education, Mechanical Eng. Educ., Electrical Eng. Educ., Industrial Chemistry Educ. and Industrial Technology Educ.). 3) The short-term course program is recommened to provide additional training and education to those candidates who already have experience in technical fields to meet an occasional demand. 4) It is necessary to add the Teaching Profession Section in the administrative organization of the College.

Idiopathic hypereosinophilic syndrome is characterized by marked elevation of eosinophil count ( >1,500/㎣) in peripheral blood without explaining etiology. It shows tissue involvement in many organs such as liver, G-I tract, myocar dium, lung, skin, kidney and nerve. Some case of hypereosinophilic syndrome with hepatic involvement have been reported, but not much. We have recently experienced a case with idiopathic hypereosinophilic syndrome of a 40 year old man who presented with RUQ pain. By abdominal CT, ill- defined subcapsular hematoma was detected. Liver biopsy showed eosinophilic infiltration within the portal tract and sinusoid. Drain procedure and corticosteroid adminiiatbrought marked improvement of clinical manifestation, hematologic abnormality and radiologic abnormality.

Aspergillus awamori와 Zymomonas mobilis로 구성된 고정화혼합 배양계의 에탄올 생산에 미치는 Triton, PVA 및 PEG의 영향

이상원,서권일,박석규,손봉수,김홍출,성찬기 순천대학교 기초과학연구소 1995 基礎科學硏究誌 Vol.6 No.-

The effects of triton-X 100, PVA and PEG on the ethanol production and raw starch hydrolysis by co-immobilized A. awamori and Z. mobilis (A-Z system) were investigated. When gel beads containing A. awamori(1.25 × 10 exp (9) spores/ℓ - gel) and Z. mobilis(0.5g cell/ℓ - gel) were cultured in 2% raw starch solution at 30℃ for 120 hours, ethanol concentration, ethanol yield (Y_p/s) and pH of culture broth were 2.8g/ℓ, 0.16 and 3.8~4.0, respectively. Ethanol production and starch hydrolysis by addition of PVA was efficient, compared to that of PEG and ethanol concentration in culture broth with 0.2% PVA was 3.56g/ℓ. At A-Z 36 culture system with changing silicon check valve for cotton plug at 36 hours in A-Z culture system, ethanol yield on glucose, Y_p/s = 0.36, showed 2 times higher than that of control culture system(cotton plug culture). Ethanol production and productivity by cultivating 85g gel beads at 30℃ in a 1ℓ jar fermentor(220rpm) of medium 500㎖ were 32g/ℓ and 1.8g/ℓ/day, respectively. After 12 hours of cultivation, gel beads were distinguished oxygen-rich surface for A. awamori from oxygen-deficient central part for Z. mobilis.
