In Vitro Antiviral Activity of Ribavirin Against Severe Fever with Thrombocytopenia Syndrome Virus Myung Jin LEE1, Kye-Hyung KIM1, Jongyoun YI2, SuJin CHOI1, Chung-Jong KIM1, Nak- Hyun KIM1, Kyoung-Ho SONG1, Pyoeng Gyun CHOI1, Ji-Hwan BANG1, Wan Beom PARK1, Eu Suk KIM1, Sang-Won PARK1, Hong Bin KIM1, Nam Joong KIM1, Myoung- Don OH1 Seoul National University College of Medicine, Korea1, Pusan National University School of Medicine, Korea2 Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by a novel Bunyavirus, severe fever with thrombocytopenia syndrome virus (SFTSV). 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.

Hyun Soo Kim, Jong Woon Cheon, Min Su Kim, Chang Kil Jung, Kyung Rok Kim, Jae Won Choi, Dong Woo Kang and Sun Young Kim1 Departments of Internal Medicine and Pathology1, DongKang Medical Center, Ulsan, Korea Actinomycosis is a chronic suppurative disease and caused by Actinomycosis species, principally Actinomyces israelii, which are part of the normal inhabitant on the mucous membrane of the oropharynx, gastrointestinal tract, and urogenital tract. It usually affects cervicofacial, thoracic and abdominal tissue. Cervicofacial type has the highest percentage of occurrence with 50%. Actinomycosis frequently occurs following dental extraction, jaw surgery, chronic infection or poor oral hygiene. It may also be considered as an opportunistic infection in immunocompromised patients such as malignancy, human immunodeficiency virus infection, diabetes mellitus, steroid usage or alcoholism. But, actinomycosis rarely occurs in adults with normal immunity and rare in the esophagus. We report an unusual case of esophageal actinomycosis which was developed in a patient with normal immunity and improved by therapy with intravenous penicillin G followed oral amoxicillin, and we also reviewed the associated literature.
일본 '백화파'에 대한 한일 비교문학적 연구 : 이광수와 김동인을 중심으로 Mainly Lee Kwang-Soo and Kim Dong-In

After this treatise grasped the point that a character of the Baekhwa school was idealism, egoism, illuminism, and art for art’s sake, it investigated what appearances that these thoughts had reflected on the Korean modern literature to make Lee Kwang-Soo and Kim Dong-In two pivot objects of study. They, Lee Kwang-Soo and Kim Dong-In met with works and thoughts of the Baekhwa school writers to go to Japan about the time when they played an important role in the Japanese literary world. But they who had quite different characters and thoughts accepted the Baekhwa school through a different logical connection with each other. When He, Lee Kwang-Soo had met with works, he formed an enlightenment consciousness of idealism, and Kim Dong-In egoism and art for art’s sake. The Baekhwa school is the representative writers in the Japanese idealism. They are an important writers from the viewpoint of on the comparative literature of Korea & Japan novel because the Baekhwa school had an effect on two writers who formed the basis of the Korean modern novel. We find out that the Baekhwa school had an enormous effect on the Korean literature if we will consider a relative importance Lee Kwang-Soo and Kim Dong-In have come into possession of the history of Korean novel.

With a view to examining the habit and method in which old people maintain and improve their health, we consulted 551 men and 444 women who were over 65 years old, and concluded as follows: 1. Habit of eating It's been revealed that most of the old people keep a regular eating hour, control the quantity of meal or eat a little food, and prefer vegetables to meat. 2. Mental health Old people feel the necessity for mental health and most of them (about 80%) keep good mental health without becoming pessimistic. Their chief concenrs have turned out to be about their sons and daughters and their own health and finance. 3. Managing Good Health It has been revelaed that old people do not possess any special kind of secret to keep good health but taking plenty of rest, regular meal, and proper exercise, and many of them (about 60%) have been shown to eat invigorant food that they can easily get around their living area. 4. Physical Functions It has been revealed that many old people are conscious of some symptoms about their parts of body and about to percent of them suffers from neuralgia. Some measures like medical aid especially for old people need to be taken as soon as possible. As we have found that the health-keeping method of old people consists plenty of rest, proper exercise, and appropriate nutrition, we can conclude that the recreatonal and culture facilities and programs for keeping old people in good health should be developed. It is also necessary to study food that contribute to their health and develop ways to get rid of the stresses to which they are exposed in their daily life. Presides, it is natural that government found an administrative department to deal with these matters effectively.

강변여과용 수평집수관을 모사하는 파일럿 규모의 모래통 실험을 수행하였으며, 다양한 출구유속에 대한 수평집수관에서의 수두분포를 구하였다. Kim24)이 수행한 실험실 규모의 수평집수관에서의 손실수두에 Kim25)이 개발한 이론 즉, 작은 규모의 수평집수관에서의 손실수두로부터 큰 집수관의 손실수두를 계산하는 방법을 적용하여 본 연구의 관측치와 비교함으로써 Kim25)의 이론이 타당함을 알 수 있었다. 또한, 이들의 이론을 적용하여 본 연구에서의 관측치로부터 실규모 집수관에서의 수두분포를 구하는 방안을 예를 들어 설명함으로써 강변여과의 수평집수관 설계방법을 제시하였다. A pilot-scale sand-box experiment simulating a lateral of collector well used in riverbank filtration was performed, and hydraulic head distributions along the lateral were measured according to the various drawdowns at the well. The results of this experiment were compared to the predicted values obtained using a theory previously developed by Kim25) in order for its validation. This theory predicts the head loss in a large-scale lateral given the loss in a small-scale one, and to have actual values for comparison, the results from a lab-scale experiment previously performed by Kim24) were employed. Comparing the experimental values to the extrapolated value indeed confirmed the validity of the theory. A procedure to determine the hydraulic head distribution of a practical-scale lateral was also presented applying the theory to the experimental result of this study in an effort to show the process of lateral design for riverbank filtration.

Background: Micafungin, a potent inhibitor of 1,3-β-D-glucan synthase, is a novel antifungal agent of the echinocandin class. In vitro study showed that micafungin was effective against Aspergillus species as well as Candida species, but clinical data on the prophylactic efficacy against invasive fungal infections (IFIs) other than candidiasis are still lacking. Materials and Methods: We identified 60 consecutive adult hematopoietic stem cell transplantation (HSCT) recipients who received at least 3 doses of micafungin during neutropenic period. Micafungin was started as an alternative in patients who were intolerant or had adverse events (AEs) to primary prophylactic antifungal agents. We retrospectively reviewed the medical records and analyzed the efficacy and safety of micafungin for prophylaxis against IFIs. Results: The patients either had autologous (n=9) or allogeneic (n=51: 1 syngeneic, 24 sibling, 26 unrelated donor) HSCT. Itraconazole oral solution (n=58) was the most frequently used first line antifungal agent for prophylaxis and was administered for median 11 days. The most frequent cause of switch to micafungin was vomiting (n=42). The duration of neutropenia and micafungin administration was median 13 and 12 days, respectively. A successful outcome was achieved in 45 (75%) patients. Empirical antifungal therapy was initiated in 13 (22%) patients. There were 2 cases (3.3%) of breakthrough fungal infections which comprised a probable invasive pulmonary aspergillosis and a possible invasive fungal sinusitis. There was no case of invasive candidiasis. A total of 53 (88%) patients experienced at least one AE regardless of causality during micafungin administration. The most frequent AEs were hypokalemia, vomiting, diarrhea, and elevated serum aspartate aminotransferase or alanine aminotransferase. Among the aforementioned AEs, only 1 case of diarrhea could be classified as a probable relation with micafungin when causality was assessed. There was no AEs that caused discontinuation of micafungin. Conclusions: Micafungin seems to be a safe and effective agent for prophylaxis of IFIs including aspergillosis as well as candidiasis in HSCT recipients. However, further large, prospective, and randomized comparative studies are warranted for aspergillosis.

본 연구는 산부식 법랑질의 타액오염 효과를 오염 시간별 전단결합강도를 알아보고 주사 전자 현미경으로 표면 변화를 관찰하고자 하였다. 타액오염 시간이 전단결합강도에 미치는 영향을 관찰하기 위하여 38%인산용액으로 15초와 60초 산부식한 후 타액으로 0초, 1초, 20초, 60초동안 오염시켜 세척과 건조 후 주사 전자현미경으로 부식면을 검경하였으며, 교정용 레진을 이용하여 브라켓 접착 후 전단결합강도를 측정하고 통계 처리하여 다음과 같은 결과를 얻었다. 1. 타액에 오염시키지 않은 15초 산부식 군과 60초 산부식 군 사이의 전단결합강도는 통계적으로 유의한 차를 보이지 않았으나, 60초 산부식군에서 전단결합강도가 조금 낮았다. 2. 15초, 60초 산부식군에서 대조군, 1초, 20초, 60초의 타액오염 시간의 차이에 따른 전단결합강도는 통계적으로 유의한 차를 보이지 않았으나, 타액오염시간의 증가에 따라 전단결합력이 낮아지는 경향을 보였다. 3. 주사 전자현미경 관찰시 대조군에서는 특징적인 부식양상을 보였으나 타액오염군에서는 유기물이 침착되어 있었다. The purpose of this study was to determine the effect of salivary contamination of etched enamel on shear bond strength of a bracket adhered to etched enamel. Eighty extracted human permanent premolars were used in this study. These samples were divided into two groups Buccal surface of samples were etched in vitro with 38% phosphoric acid for 15 seconds and 60 seconds. Each group was divided into four subgroups. Etched enamel surfaces were contaminated with saliva for 0,1,20,60 seconds, washed and dried. Test surfaces were examined using scanning electron microscope(SEM). The shear bond strength of each sample was determined with a universal testing instrument(Instron Co. Model 4201). Results were as follows: 1. Salivary contamination for 1, 20, 60 seconds did not affect shear bond strength when compared with the uncontaminated enamel group. 2. There was no significant difference(P>.05) in shear bond strength between 15 sec, and 60 sec, etching in uncontaminated enamel groups. 3. When samples were examined using SEM, organic materials coated enamel surface masked the etched pattern partially.

Purpose: Angiogenesis is important for the proliferation and the metastasis of solid tumors. The growth of a solid tumor is widely recognized to depend on the process of neovascularrozation. Without angiogenesis, tumors cease to grow beyond even a few milimeters in diameter. It has been shown that tumor vascular density is an independent prognostic marker in several types of human tumors and is known to correlate with poor prognosis. To date, many angiogenic factors have been identified, such as transforming growth factor-α(TGF-α), transforming growth factor-β(TGF-β), fibroblast growth factor family(FGF), vascular endothelial growth factor(VEGF), platelet derived endothelial cell growth factor(PD-ECGF), tumor necrosis factor-α(TNF-α), and angiogenin. Hepatocellular carcinoma(HCC) is the second most common tumor in Korean males and is known as a typical hypervascular tumor with frequent portal vein invastion. The authors identified the expreesion of VEGF, TGF-β1, and b-FGF in HCC specimens and evaluated the relationship between these growth factors and the clinicopathologic characteristics of HCC. Method: We reviewed the medical records of 30 patients who were diagnosed as hepatocellular carinoma treated with hepatic resection between January 1994 and December 1998 in Soonchunhyang University Chunan Hospital. The selection of the cases was decided according to the condition of paraffin block fixation. The prognostic factors such as age, sex, tumor size, concentration of serum α-fetoprotein, presence of liver cirrhosis, presence of tumor emboli in portal vein, TMN stage, amount of transfusion during the operation, hepatitis B virus(HBV) infection, and Edmonson-Steiner(E-S) grade were investigated. Relationship between the prognostic factors and the immunopathologic expression of the TGF-β1, b-FGF, and VEGF was examined. Result: Thirty patients (24 males, 6 females) were included in the current study. The patient's mean age was 50.6 years and the age ranged from 36 to 65 years. The mean size of the tumor was found to be 5.2cm. All the patients were follewed up for 7 to 63 months. Child's classification A patients were 23(76.7%)cases, B patients were 7(23.3%)cases, and C was none. Immunohistochemical staining of HCC tumor mass in VEGF expression patients were 17(56.7%), b-FGF expression patients were 10(33.3%), and TGF-β1 expression patients were 10(33.3%). VEGF expression or more than one positive expression among the three factors correlated with tumor size and the stage of HCC but did not correlated with other clinicopathological characteristics. TGF-β1 and b-FGF did not correlate with any clinicopathological characteristics. Conclusion: The results suggest that the expression of VEGF or more than one positive expression among the three factors in HCC cells may be a significant prognostic factor of HCC.

This study is for the purpose of examining effects related to duty stress & duty satisfaction due to Police of officers' Physical exercise participation, helping more efficient duty Performance, and positive self-formation. Furthermore, providing basic data that can be helpful to the improvement of police duty. The objects of the study were police officers who were taking part in education program in Police Comprehensive Academy, and the number of police officers who answered the questionnaire is 356 police officers, but data used for real analyzation consist of 300 police officers. The tools for the study were based on Ivancevich's duty stress model in order to measure stress. And also questionnaire used on Kim yoon hee, Kim mae ja, Jo kyung soon, Lee hart kyung's study was used as a complementary tool. The instrument for measuring duty satisfaction rate was developed by Paula. And I used the instrument based on questionnaire that was used by Ko hee soon, Park ki hyung, Kim bum sik, Lee jong kil, Lim bun jang, Jo young chang, Hackeman, Lawlar and Oldham's study. Data analysis is Processed statistically with SPSS/PC+, I Performed T-verification, ANOVA-verification in accordance with the purpose of study after getting the percentage and the real number in case of general characteristics of the objects, and examine an average and standard variation in case of duty satisfaction and duty stress rate. And I set an err rate to 0.5. I verificated co-relation between stress and duty satisfaction with Pearson Correlation Coefficient. The result of the study is as follows, The first, among sociological characteristic and external factor of duty satisfaction, The married is more significant statistically(p< .01, p<.05) compared to the unmarried in terms of compensation system and working condition , which are subfactor of duty satisfaction . In terms of the length of one's service, the longer service term one has the higher significance level one shows in compensation system, working condition, safety, and external factor which are sub-factors of duty satisfaction In terms of an academic background, one who graduated from a high school shows significance statistically only in working condition which is a subfactor of duty satisfaction compared to other people (p<0.5) The second, among sociological characteristic and internal factor of duty satisfaction, the married is more significant statistically(P<.05) compared to the unmarried in terms of achievement which is a subfactor of duty satisfaction. In terms of age the older one shows higher significance level in stability which is a subfactor of duty satisfaction compared to younker one(p<.05) In terms of the length of one's service the longer service term one has ,the higher significance level one shows(p<.01, p<.05). The third, in terms of duty stress due to sociological variable, the married is more significant statistically(p<.05) in case of stress stems from police duty than the unmarried Interms of age, welfare and duty stress are significant statistically(P<.05) Interms of the length of one's service, police's work is significant statistically(P<.05). One who graduated from junior college is significant statistically in police's work, welfare, stress and gets a lot of stress in personal relations(p<.05). The forth, groups participating in exercise are more significant statistically in stability(p<.001), feeling of stability(P<.001), achievement(p<.001), internal factor(p<.01), external factor(p<.05) than croups not Participating in exercise. The fifth, groups participating in exercise are more significant statistically only in personal management than groups not participating in. The sixth co-relation between duty satisfaction and duty stress is r=-0.3814, (P<.001) ,which shows opposite co-relation. so, a result the more stress one has, the lower duty satisfaction he gets.
