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.

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.

This research examines the similarities and the differences in 「patterns of speech act realization」in disagreement situations between Native Korean Language Speakers(KK), Japanese Learners of Advanced or Highly-Advanced Korean Language(JK) and Native Japanese Language Speakers(JJ) from Interlanguage Pragmatics' viewpoint through comparison analysis. In this regard, Discourse Completion Test(DCT) was used as an investigation method, and the questions were classified into twelve disagreement situations according to social variables such as intimacy, status, official and personal situations. In order to analyze the collected data, the Head Acts were classified as 「criticism, suggestion, request to talk further, acceptance, reason · explanation, avoidance, insistence」, and the Adjuncts were classified as 「use of formal name-titles, gratitude expression, apology expression, expression of desire for acceptance, emphasis on sympathy, addition expression」. In Chapter I of this paper, the need and the objective of this study are introduced as well as various preceding research of the Korean language education field including past disagreement speech act studies. Chapter ll explores speech act theories and Interlanguage Pragmatics which constitute the logical foundation of this thesis, and reconstructs disagreement speech act strategies and social variables necessary for the concept of disagreement and for analyzing experiment results by modifying to suit this investigation. Chapter III describes investigation tools, creation procedures, data analysis methods and examination tools. In addition, this experiment was carried out after two preliminary experiments. In Chapter Ⅳ, analysis for each group according to twelve situational strategy analysis and three social variables, intimacy, status, official and personal situations were carried out, after analyzing comprehensive strategies for each group regarding the results gained through this experiment. As a result, the order of frequency in use of the Head Acts were 「insistence-reason · explanation-suggestion-criticism」 while request to talk further, acceptance and avoidance strategies were hardly used at all. Performing analysis by social variables, the three groups all used the following order of strategies in disagreement situations with highly intimate people: 「insistence-reasonㆍexplanation-suggestion」. In the case of disagreement situations with a person with higher status, the order 「reasonㆍ explanation-insistence-suggestion」 as used, while 「insistence-suggestion-reason · explanation」 was used for a person of lower status. In official situations, the order of the strategies is appeared to be 「insistence-suggestion-reasonㆍexplanation」 Thus, for all three groups, there seemed to be no difference in strategy order in disagreement situations with highly intimate people, people with higher/lower status, or in official situations. The difference in speech act realizations according to situations of the three groups was that JJ seemed to show a higher tendency to expect others to follow through active insistence than KK, as seen from the fact that JJ uses more insistence strategies than KK. JK, on the other hand, appears to use strategies resembling those of KK as its understanding of the Korean language and the Korean culture is increased. Although all three groups displayed low levels of Adjuncts usage, KK used addition expression while JK and JJ used apology expression the most In disagreement situations. The difference in the groups according to social variables is that in low intimacy cases, KK explains the reason to others when JK and JJ expect others to follow by using assertion strategies. In personal situations, KK seeks to obtain consent from others through explanation while JK and JJ display high tendencies to expect others to follow by using assertion. The results of this investigation is summarized in Chapter V Looking at the results, in low intimacy cases and personal situations, JK uses different strategies than those of KK and thus fails to properly deliver personal feelings causing possible misunderstandings. Therefore, it seems necessary for Korean pragmatics education for JK to use more expressions that are used by KK which will enable JK to respect others and deliver personal opinions correctly at the same time. The results of speech act comparison analysis in disagreement situations for the three groups suggests new ideas for Korean education fields aiming for attaining communication skills. Disagreement occurs in various situations and may damage the face of others, so this study may play a significant role as primary data source for Korean Speech Act education. With continuous in-depth studies of Interlanguage speech act between languages which are similar to Korean culture considering various social variables, it will contribute to more effective Korean teaching-teaming and textbook development.

To solve "software Crisis", Software Engineering which adopts the concept of engineering in the development of software has been introduced. Analysis and Design are the most important steps in "Software Life Cycle". If Analysis and Design work properly, development cost, time, and maintenance cost are reduced. Until now, we have many methodologies which test after software developed, but don't have one which test design itself. In this paper, we propose a methodology and diagram to conduct testing in design time. New diagram is very similar to the conventional DFD. The DFD that can be executed is called message Transmission Diagram. All object on the Message Transmission Diagram are to execute independently with data flow converting operations, which makes it easier to find errors of data flow on design. Also, to validate usability of methodology proposed, we implement tol which support new methodology.

최향하,김미영,김도진,유지원,장정화,박수정,박재성 한국의료QA학회 2005 한국의료질향상학회지 Vol.12 No.1

Background : The necessity of unify and standardize codes used at hospital has been emphasized since OCS (Order Communicating System) was adopted. Therefore, the purpose of this study were to standardize operation code by continuous training of the ICD-9-CM code that is used as standard code in OCS program at operating room. Method : In 400 operation data, operation code entered in OCS program at operating room was compared to operation name recorded in medical record. In addition, a matching rate between input data of operation code by medical record department and computing input data of operation code in 3,710 cases was compared for each department. User operation name and operation code were matched and major diagnosis by operation department and operation name were also matched. Results : User operation name was reflected in operation classification code in detail, and operation code entered on user was registered. Input rate and matching rate of operation code were gradually improved after improvement activity. In particular, a matching rate was high at ophthalmology where operation name is segmented. Plastic surgery and orthopedics with a lot of emergency operation and comprehensive operation name show low input rates. Conclusions : As the medical field makes progress in computerlization, awareness of information exchange and sharing becomes higher. Among codes to classified medical institution, codes related to surgical operation are all different by user of hospital and department. Computerlization and standardization is essential. And when efforts of standardization continue in alliance with individual hospital and institution, initiative of preparing medical policy data at a national level will be accelerated.

Purpose: This study examined the clinical success rate of Mg titanate implants (M Implant system, Shinhung, Korea), which employ a Mg coating method, by evaluating the marginal bone loss and implant stability using radiographs and Osstell, over a 1 year. Materials and methods: The locations of the implants placement were divided into 4 areas; the maxillary and mandibular premolars and molars. In the maxilla, 8 and 9 implants were inserted in the premolar and molar areas, respectively. In the mandible, 11 and 51 implants were inserted in the premolar and molar areas. Marginal bone loss and ISQ of all implants (79) were measured after insertion, mounting the prosthetic appliance, and 1, 3, 6, and 12 months after loading. The marginal bone loss was measured from the radiograph using XCP bite, which was customized, and the implant stability measured using Osstell. Fisher's exact test (α=.05) was used to compare the success rates of each region. Results: The mean marginal bone loss for the upper and lower jaws were 1.537 mm and 1.172 mm. The mobility showed a non-significant reduction or increase according with time. The success rates were accounted for 94.12% and 98.39% in the upper and lower jaws; the premolars and molars were accounted for 100% and 96.67%. The two cases of early failure resulted from failure of primary stability during implant insertion. The late failures were not observed for 1 year after adding a loading to the implants. Conclusion: The Mg titanate implant showed good primary stability and good clinical results in both healing and function. 연구 목적: 부분 무치악 환자에서 Mg titanate implant (M Implant system, Shinhung, Korea)의 보철후 1년간의 방사선사진을 이용한 변연골 흡수량과 Osstell을 이용한 임플란트 안정성 평가 결과를 분석하여 임상적인 성공률에 대해 알아보고자 한다. 연구 재료 및 방법: 38명의 환자에 79개의 임플란트를 식립하여 보철 후 1년 동안 변연골 흡수량, 임플란트의 동요도, 임플란트 식립 위치에 따른 분포 및 성공률, 보철 전후에 따른 성공률을 분석했다. 결과: 변연골의 흡수량은 보철물 장착 후 1년간의 평가에서 상악에서는 평균 1.537 mm, 하악에서는 평균 1.172 mm의 변연골 흡수가 관찰되었으며, 전체적인 상하악의 평균 변연골 흡수량은 1.255 mm로 관찰되었다. 수술 후 시간이 경과함에 따라 ISQ값은 미약하게 감소하였다가 증가하는 경향을 보였으나, 상악과 하악 모두에서 식립 당일 이후 예비 인상일, 최종 보철물의 장착일과 주기적인 평가 기간 동안 ISQ값의 큰 증가나 감소를 나타내지는 않았다. 성공률은 상악에서의 94.12%였고, 하악에서의 98.39%였다. 결론: 본 실험의 결과로 미루어 Mg titanate implant는 임상적으로 양호한 결과를 보여주었다.
