Hantavirus is a genus of the Bunyaviridae family consisting following serotype groups: Hantaan, Seoul, Puumala, Prospect Hill, Thailand, Belgrade, Thotta palayam, Sin Nombre. Most of Hantavirus group have been associated with many clinically similar disease known collectively as hemorrhagic fever with renal syndrome (HFRS). Hantaan virus is the prototype of the genus hantavirus, originally isolated from Apodemus agrarius. Bat was found as a natural host for Hantaan virus in Lee's lab for the first time. Then, Hantaan-like virus was isolated Hantaan-like virus from bat. To identify hantaviruses that are present in Korea among bats, bats were collected from Jeong-Sun, Won-Joo, Chung-Ju and Hwa-Cheon area, RNA was isolated from lung and serum. RT-PCR was performed with a universal primer from M segment. Nested RT-PCR was carried out to differentiate Hantaan, Seoul and Puumala virus using serotype specific primers. As we expected, Hantaan viruses were detected in bats and Seoul virus was not detected. Interestingly, Puumala viruses were also detected in bats from Won-Ju, but not in other areas. Puumala virus is originally isolated from Clethrinomys glareolus, and cause light HFRS. Recently, Paradoxomis webbiana, a wild bird turn out to be a reservoir for Puumala virus in Korea. These data indicate that bat is a new natural reservoir of Puumala virus.

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.

Youn-Kyoung Lee. 2021. Semantic Structures of Epistemic Modals: Teachers’ Understanding and Teaching Experience. Studies in Modern Grammar 109, 83-104. The study aimed at examining native English teachers’ and Korean EFL teachers’ understanding and teaching experience of epistemic modals. For the study, a total of 51 teachers participated in the online survey, and 11 of them had a follow-up interview. The results revealed that Korean teachers’ understanding was surprisingly low, indicating 10.94% of accuracy rate on average while native English teachers showed 94.74% of accuracy rate. The two groups’ mean score was statistically significant (p<.05). Concerning both groups of the teachers’experience of epistemic modals, while 78% of them had teaching experiences, both groups of the teachers merely focused on forms and meanings, not semantic system, which concerned a hierarchy for logical meanings. Finally, significance of understanding and using functions of epistemic modals was discussed.

This study concentrates an the trail of the CNU(Chungnam National University) forest. The amount of use and the pattern of damage are considered, as well as the extent of environmental damage. Finally, some managerial strategies are proposed in connection with sustainable maintenance. The trail of the university forest is composed of three sections; one is the neighborhood park and the Institute of Information Technology/Communications, the second is the Institute of Information Technology/Communications and the Dormitory, and the third section is the Dormitory and the Foreign prof's Apt. The total length of the trail is 2.6km. The daily amount of use is 1,269 visitors per day. The amount of using increased three times the amount of that in 1998. This study shows the pattern of damage of the trail in the order of root-exposure, widening, rock-exposure, deepening and the divergence in the frequency of occurrence of all these factors. Environmental damage is also graded thus: grade 3 is 27.4m, grade 4 is 0.8m, grade 5 is 1.5m, and grade 6 is 0.2m. Accordingly, some managerial strategies were proposed in connection with the sustainable trail maintenance.

Comparative Study on the Use of Pharmacist Advice between U.S. and Korea

( Lee,Eui-kyoung ) 한국보건사회연구원 1990 保健社會硏究 Vol.10 No.1

This study investigated the differences in the use of pharmacist advice between the U.S. and Korean university students. The variations in a person`s decision to use pharmacist advice in response to symptoms were examined based on Andersen`s model. A pre-experiment was conducted for the students taking similar courses using a self-administered questionnaire. For the 18 hypothetical symptoms, they were asked to decide how to respond to each of them for 7 days. After controlling for the symptom severity, U.S. students were apt to use pharmacist advice for less days, no matter how they perceived them. The results also showed that there were meaningful differences in the use between two countries after adjusting for differences in the predisposing, enabling, and need characteristics. A revised four stage model was successful in explaining the differences in the utilization. Application of modified version of Andersen`s model to U.S. and Korean university students yielded very unique findings, where the most predictive power was in predisposing variables. The meaning of the “country" was discussed in relation to the difference in the drug regulatory environment.

신장이식은 환자의 삶의 질을 높이고 거의 정상적인 사회생활을 가능하게 함으로써 말기신부전 환자의 3가지 신대체 요법(혈액투석, 복막투석, 신장이식) 중에 가장 효과적이고 각광받는 치료법이라 할 수 있다. 최근 들어 의료기술과 의학의 발달로 신장이식의 성공률은 과거에 비해 비약적으로 높아지고 있으며 국내에서도 점차 신장이식수술을 받는 환자가 증가하고 있으나 서울이나 다른 대도시에 비해 의료환경이 열악한 중소도시나 지방의 병원에서는 아직도 시행하지 못하고 있는 형편이다. 이에 저자들은 경북 최초로 자체 의료진에 의해 고혈압과 말기 신부전으로 동국대 포항병원에서 혈액투석을 받고 있던 32세의 남자환자에게 부인으로부터 신장을 제공받아 신장이식을 성공적으로 시행하였기에 문헌고찰과 함께 보고하고자 한다. Kidney transplantation is the preferred treatment modality for many patients with end-stage renal disease (ESRD), because it offers improved quality of life over both hemodialysis and peritoneal dialysis. Patients who do well after transplantation generally report improvement in vitality and freedom to return to the style of life that they experienced before their progression to ESRD. Recently, the success rate of kidney transplantation is greatly being increased as the surgical technique and immunosuppressive drugs are developed. Kidney transplantation is also popular in Korea which has good result. But, until now the general hospitals which are located at small city can't try the kidney transplantation because they don't have proper facilities and experts. We firstly experienced a case of kidney transplantation in a 32 years old man with hypertension and chronic renal failure at KyoungBuk province. So we report this case with references.

To cope with corporation environments such as global economy era, increased product diversity and rapid market environmental change, the production system should be operated with capabilities to supply products in time and the lowest price that meet customer's demands. Therefore, the production system has been changed from mass production system of conveyor type to U-line system based on JIT according to market environmental change. Scheduling on the production activities is to decide proper time and methods for each activity by supplying materials within limited time. If the scheduling, however, is not favorable, it will not only fail to meet appropriate supplying time but also cause inefficiency caused by the low utilization of diverse elements for production activities. Therefore, the study is to understand characteristics of U-line and look over the theoretical background of scheduling planning. This application was developed by using Visual basic 6.0 and Active X control.

Solvent extraction and stripping experiments were conducted to separate iron from a spent FeC13 etching solution containing nickel. In the operation of mixer-settler, 7 extraction stages with 1.0 M Alamine336 in toluene, led to 98% extraction percentage of iron at equal phase ratio, when the flow rate of organic and aqueous were 35 mL/min and 5 mL/min, respectively. At equal phase ratio of aqueous to organic, 10 stripping stages with 0.01 M HC1 solution resulted in 99% stripping percentage of iron when the flow rate of stripping solution and loaded organic were 5 mL/min and 35 mL/min, respectively. The concentration of iron in the stripped solution was 133 g/L and this solution could be reused in the etching of nickel lead frame. (Received June 15, 2004)

Improvement of adhesion properties of glass prepared using SiC‑deposited graphite mold via low‑temperature chemical vapor deposition

Kyoung‑Ho Kim,Kuk‑Jin Hwang,Heesoo Lee,Seong‑Min Jeong,이명현,배시영 한국세라믹학회 2020 한국세라믹학회지 Vol.57 No.1

Compression glass molding is a promising technique for mass production of near net-shaped, high-precision, and low-cost optical glass elements. However, the glass molding process causes the damage of glass and the mold during demolding because of the chemical or physical adhesion of the glass to the mold. To overcome this limitation, graphite molds are used owing to their good lubrication and easy machining. However, graphite materials show rapid oxidation at high temperatures in the presence of oxygen. Therefore, in this study, a thin SiC coating layer was deposited on the graphite mold using the chemical vapor deposition (CVD) method to utilize the lubrication properties of graphite and the anti-oxidation properties of SiC. The specimen obtained using the low-temperature CVD method showed high carbon content and good lubrication properties than that obtained using the high-temperature CVD method.

Objective: To evaluate hyperlipidemia, a msjor tisk factor of coronary artery disease, frequently asscoiated with gout patients, we compared the mean lipid level of gout patient with that of non-gout male and accessed statistical significance for treatment of gout patient. Method: This study ws performed in the 266 male gout outpatients of the CAU medical center, who had serum lipid level test from Apr. 1996 to Aug. 2000. Serum uric acid, total cholesterol, triglyceride, HDL -cholesterol, and LDL-cholesterol level were measured after 12 hours of fasting. The patients with high lipid level were further evaluated into each type of the hyperlipidemia through electrophoresis study, and the test results were compared with that of the non-gout male adults(40∼60yr), and the statistical significance was examined. Results : The gout patients showed high levels of total cholesterol, triglyceride, and LDL-cholesterol. Especially they showed high level of triglyceride and LDL-cholesterol which suggested as the risk factors of atherosclerosis and coronary heart disease, but shoewed low level of HDL -cholesterol. But there were no definite relations between lipid level and other factors auch as age of patient, initial uric acid ;eve; and duration od gout. Conclusion: To evaluate the risk factors of atherosclerotic change of cadriac vascular system in gout patient, screening tests of serum lipid level of the patient seem mandatory.
