No effective antiviral therapy is proven yet, but clinical use of ribavirin (RBV) has been tried. We investigated the antiviral effect of RBV against SFTSV in vitro. Methods: To test for cytotoxicity of RBV, Vero cells were treated with different concentrations of RBV (3.90 to 500 μg/mL, two-fold dilution) and analyzed by cell viability MTS assay 48h post-infection. To determine antiviral activity of RBV against SFTSV, Vero cells were infected with SFTSV strain Gangwon/Korea/2012 at 100 TCID50 (50% tissue culture infective dose) per well in a 96-well plate, and RBV was added at the concentrations showing no or minimal cytotoxicity. Viral RNAs were extracted from the culture supernatants and quantifi ed using one-step real-time reverse transcription- PCR to amplify the partial large segment of SFTSV. Statistical analysis was done by one-way ANOVA with Tukey`s post hoc test. Results: Cytotoxicity due to RBV was not observed at RBV concentration =31.3 μg/ mL. Viral RNAs at 24h post-RBV treatment were reduced with increasing RBV concentrations (1-32 μg/mL), compared with those of mock-treated cells (P <0.01, Figure). Half maximal inhibitory concentration (IC50) of RBV was 3.69 μg/mL at 24h post-RBV treatment. Conclusions: Our study shows that RBV has antiviral effect against SFTSV in a dose-dependent manner. Further studies are required to evaluate the effi cacy of RBV in SFTS.

Bliese와 Halverson(1998)은 집단수준의 효과를 분석하는데 있어서 기존에 사용되어 온 eta-squared 보다는 eta-squared 값이 사용되어야만 한다는 것을 주장하였다 그러나 이들이 제시한 수정된 eta-squared 접근은 다음과 같은 한계점을 가지게 되는 바 첫째, 이 접근법은 개인수준의 데이터를 집단 수준의 데이터로 만드는데 있어서의 정당성을 제공하는 기준을 구체적으로 제시하고 있지 못하다는 것을 들 수 있고, 둘째, 이 접근법은 또한 집단 내 효과를 용인하고 분석하는 기준을 제공하고 있지 못하다는 점을 들 수 있다 본 논문에서는 이러한 한계점을 극복할 수 있는 몇 가지의 대안을 제시하고 있으며, 이와 더불어 개인수준의 데이터를 집단 수준으로 만드는 것에 대한 정당성을 위한 또 하나의 추가적인 절차를 제시하였다 Bliese and Halverson(1998) argue that corrected eta-squared, rather than eta-squared, should be used for analyzing group-level effects However, their proposed corrected eta-squared approach has the following limitations (1) it fails to specify a criterion for justifying the aggregation of individual-level data to the group level and (2) it fails to specify a criterion for analyzing and allowing for within-group effects In this paper, we suggest several alternatives that overcome these limitations We suggest an additional procedure for justifying the aggregation of individual-level data to the group level

Background : This investigation was to perform the epidemiological surveillance and genetic analysis on respiratory viral agents from children with acute respiratory infections in Gwangju. Materials and Methods : For this study, 3,695 specimens obtained from patients with acute respiratory infections were collected by collaboration with pediatric hospitals in Gwangju between 2005 and 2007. Specimens were screened for 8 respiratory viruses including influenza viruses (IFV), human rhinoviruses (HRV), human coronaviruses (HCoV), adenoviruses (ADV), parainfluenza viruses (PIV), human enteroviruses (HEV), respiratory synthitial viruses (RSV) and human bocaviruses (HBoV). Respiratory viruses were detected using multiplex (RT) PCR with viral specific primers. Results : Out of 3,695 specimens, the ratio of virus detection was 24.9% (919). Overall, HRV (35.5%) and IFV (34.9%) were the most common viruses found, followed by HBoV (14.8%), HCoV (10.6%), RSV (3.7%), ADV (3.4%), PIV (3.2%) and HEV (3.0%). In addition, multiple infections were detected in 80 patients (8.7%). When the prevalence was analyzed according to season, HBoV, IFV and HCoV showed two epidemic points in late spring and early winter. ADV, HRV, RSV PIV and HEV, however, were all found to have only one epidemic point, with RSV being most common during winter and the others being most prominent during spring. Conclusions : Through this epidemiological surveillance, the respiratory viruses prevalent in children in Gwanaju area were investigated. We strongly recommend the development of nationwide policy for the management of prevalent respiratory virus that includes long term collection of data and samples, vaccine development and prevention education of the misuse of antibiotics.

이 연구는 트레드밀 운동과 키네시오 테이핑의 효과에 따른 폐활량의 변화를 알아보기 위해 26명의 비흡연자가 참가하였으며 키네시오 테이핑을 적용하지 않은 그룹과 키네시오 테이핑을 적용한 두 그룹으로 무작위로 배정하고 각 군들을 주 3회 6주간의 트레드밀 훈련을 실시하였다. 실험 전과 후, 스파이로미터를 사용하여 키네시오 테이핑의 적용 따른 폐활량 변화 효과를 측정하였다. 이 연구의 결과를 종합해보면 키네시오 테이핑을 적용 그룹에서 적용하지 않은 그룹에 비해 FVC, FEV1에서 유의한 증가를 보였다. 이러한 결과는 건강한 성인에서 키네시오 테이핑을 적용한 경우 키네시오 테이핑을 적용하지 않고 트레드밀 운동을 한 경우보다 폐활량의 향상에 효과적이라고 생각되어진다. The purpose of this study was to investigate the variation of vital capacity(VC) according to the effects of kinesio taping with treadmill exercise. Twenty-six non-smokers were participated in this research and these subjects were randomly assigned into two groups. To measure the VC variation effects of kinesio taping, spirometer was used. The collected data were analyzed statistically by using a paired Mauchly test and repeated measure ANOVA. The results of this study were as follows; A group: treadmill with kinesio taping B group: treadmill without kinesio taping. Between A and B, there were significant differences. In the case of A group, there was 11.66% increase of VC, during 3 weeks experiment(p<.01). In the case of B group, there were significant differences, 3.35% increase of VC, during 3 weeks taping intervention(p<.01). After 6 weeks experiment, the improvement of VC shown a significant difference with intergroup (p<.05). From this result, it was revealed that treadmill exercise with kinesio taping was effective to improve VC to healthy adult than treadmill exercise without kinesio taping.

金善浩,李秀京,金泰延,康娜榮,金亨駿 弘益大學校 科學技術硏究所 2005 科學技術硏究論文集 Vol.16 No.-

Nickel induced crystallization of amorphous silicon (a-Si) has been studied by selective deposition of Ni on a-Si thin films. The kinetics of crystallization for MIC was found to be greatly enhanced than that of SPC. Ni-induced crystallization is a promising technique for low-temperature fabrication of poly-Si thin-film transistors needed for large area applications. Lateral growth of polycrystalline silicon mediated by the formation of nickel silicide, has been successfully employed for the fabrication of high-performance TFTs. A-Si thin films on which Ni films were deposited with various thickness were crystallized as a function of annealing temperatures. Throughout the thesis work, wise choice of both the thickness of Ni and the annealing temperature was found to produce poly-Si films with high quality, thus potentially resulting in the production of TFTs with high performance.

Purpose: To evaluate the antiadhesive effects and safety of an oxidized regenerated cellulose (Interceed) after thyroidectomy. Methods: Seventy-six thyroidectomized patients were prospectively randomized into two groups with regard to the use of Interceed. We evaluated each group for their adhesive symptoms using four subjective and four objective items at the 2nd week, 3rd and 6th month after thyroidectomy. All patients were examined for vocal cord motility by indirect laryngoscope at each period. Results: Total adhesion scores at each postoperative follow-up period decreased with time, but were not significantly different in each group. The median score for swallowing discomfort for liquid was significantly lower in the Interceed group than in the control group 2 weeks after surgery. In addition, the severity of skin adhesion to the trachea was reduced in the Interceed group compared with the control group 6 months after surgery. During the study, there were no adverse effects or significant differences in postoperative complications between the groups. Conclusion: Interceed appeared to be safe and effective in improving neck discomfort at early postoperative periods and preventing skin adhesion to the trachea 6 months after thyroidectomy.

초록 본 연구의 목적은 조직 뿐만 아니라 개인 종업원들이 경력개발에 대한 책임을 느끼고 노력 을 하는 것이 그렇지 않을 때보다 효과적인지를 검증하는데 있다. 이를 위하여 길레이 (Gilley)가 주장한 경력개발활동을 기초로 개인개발활동과 조직의 경력개발활동의 시행여부, 활용정도, 파급효과 등에 대해 종업원이 지각하는 형태에 따라 경력개발유형을 부진 미흡형, 개별 분리형, 상호 보완형으로 분류하였으며, 이들 유형이 조직몰입과 이직의도, 주관적인 성과 등에 달리 영향을 미칠 것으로 보았다. 즉, 개인의 경력개발활동과 조직의 지원활동이 활발한 상호보완형의 경우 조직몰입도나 성과가 높게 나타날 것이고, 이직의도는 낮게 나타날 것이며, 이와 반대로 개인의 경력개발활동도 부진하고 조직의 지원활동도 미흡한 부진미 흡형의 경우 조직몰입과 성과는 낮게 나타날 것이고, 이직의도는 높게 나타날 것이란 가설 을 설정하였다. 12개의 금융회사의 직원들로부터 수집한 자료를 분석한 결과 경력개발활동 유형중 상호보완형에 속한 직원들은 높은 조직몰입과 주관적인 성과를 보였으며, 이직의도 는 낮은 것으로 나타났다. 반대로 부진미흡형에 속한 직원들은 낮은 조직몰입과 주관적인 성과를 보였으며, 높은 이직의도를 가지는 것으로 나타났다. 또한 개별분리형에 속한 직원들 은 중간 정도의 조직몰입과 성과를 보였으며, 이직의도 역시 중간 정도로 나타났다. 이러한 결과 결론부분에서 개인과 조직목표의 조화측면에서 논의되었다. <Abstract> The purpose of this study is to investigate the effects of Career Development Activites(CDA), which improves QWL and expedites the attainment of organizatonal goal, on performance. To accomplish this purpose, we classified CDA types into three dimentions(stagnation type, separation type, integration type) according to the employees perception regarding personal and organizational activities and analyzed the effects of CDA on performance such as organizational commitment, subjective outcome, and turnover intention. The results from 12 financial company showed that1) with regard to the level of organizational commitment and subjective outcome, employees in the separation type among CDA significantly and lowly differd from those in the stagnation type, 2) as for the level of turnover intention, employees in the separation type significantly and highly differed from thise in the integration type and significantly and lowly differed from those in the stagnation type. These results were discussed in terms of the fit between person and organizational goals.

천은사의 이승휴 유적지 발굴기

金慶洙 중앙대학교 인문과학연구소 2001 人文學硏究 Vol.32 No.-

천은사는 삼척에 있는 절이다. 이 절은 백두 대간의 줄기인 두타산 자락에 있다. 절경 으로 이름난 두타산이 바다로 향해 뻗어 가다가 삼척의 미로면에 이르러 세 봉우리로 뭉쳐지는데 그 봉우리 아래쪽 양지 바른 곳에 위치하고 있다. 내가 이곳을 찾은 것은 1992년이었다. 그때 나는 울산의 처용 설화에 심취해 있었다. 그 중에서도 처용 설화에 나오는 망 해사의 존재에 대하여 사회사적 해석을 할 수 없을까 하고 고심하고 있었다. 절이란 불교포교만을 위해서 운용되는 것이 아니라는 생각이 삼국유사를 읽으면서 여러 차례 생각났기때문이었다.

시멘틱 웹 기반의 비교구매 에이전트를 위한 동적 웹 온톨로지 시스템에 대한 연구

김수경,안기홍 한밭대학교 정보통신전문대학원 2005 정보통신전문대학원 논문집 Vol.3 No.1

기존 전자상거래 플랫폼과 컨텐츠는 데이터의 확장 및 통합이 고려되지 않은 HTML을 중심으로 한 표현 기반 기술로 되어 있고, 특히 전자상거래 사이트별로 상품 정보에 대한 분류체계가 상이함으로 인해 구매자에게 상품별 비교와 검색에 있어서 많은 시간이 낭비되고 또한 정보의 공유가 어려운 기술로 인하여 판매자와 구매자 모두의 요구를 만족시키지 못하고 있다. 본 논문에서는 최근 차세대 웹 기술로 각광받고 있는 시맨틱 웹 기반 기술인 RDF/RDFS를 이승하여 기존 이종의 상점에 제시된 상품 정보를 RDF 문서로 생성하고, Web Ontology Language(OWL)를 사용하여 상품 지식 기반 온톨로지를 구축한 뒤, RDF 문서와의 분석과 매칭을 통하여 이종의 상점에 표현된 상품을 실시간으로 비교 검색하고 동적으로 상품에 대한 지식 기반 온톨로지를 생성하는 웹 온톨로지 시스템을 설계 제안하였다. The existing e-commerce platform and contents are made of expression-based technology HTML that expansion and integration of data weren't considered. Besides, a lot of time is wasted in comparison and a retrieval of product to a buyer, because a classification System about product information is different every electronic commerce site, and cannot satisfy demand of seller and buyer all by trouble of information sharing an technology. In this paper, use the RDF/RDFS which is Semantic Web-based technology to get attention with next generation Web technology recently and it generates product information of the existing store in a RDF document, and after use OWL, and establishing product knowledge-based ontology, and through analysis and matching with a RDF document, A design proposed a System that compare a product expressed to an each e-commerce site by real time, and to retrieval and redefine product knowledge-based ontology as dynamic.
