A new virus with a dsRNA genome was isolated and characterized from the Suhan-neutari strain (ASI 2504) of Pleurotus ostreatus, which was characterized as long and slightly bent with small caps on the stipe of fruit body. Thirty nm isometric viruses with three dsRNA segments (approximately 2.0, 1.84 and 1.82 kb in sizes) were isolated by ultracentrifugation in sucrose gradients. Western analysis of protein extracted purified viruses with anti-virus polyclonal antibody confirmed that viruses have two specific proteins (36 and 68 kDa). Computer analysis of 2.0 kb segment shows that high sequence identity with RNA-dependent RNA polymerase (RdRp) of partitiviruses, respectively. When compared to other dsRNA mycoviruses in a phylogenetic analysis, OMDV was most related to Pleurotus ostreatus virus 1.

본 연구에서는 로드샵 화장품 브랜드의 쿠션파운데이션에 대한 소비자 평가를 분석하였다. 유비쿼터스 시대가 도래함에 따라 소비자의 정보 습득 행태는 다양해지고 서로의 생각과 정보를 공유하는 것이 일상화 되었으며, 이에 화장품의 구매결정에 영향을 미치는 요소를 파악하였다. 브랜드 A, B, C, D, E사의 쿠션 파운데이션 중 주력 제품 A, B, C, D, E를 대상으로 「화해」 어플리케이션에 게시된 다섯 가지제품의 진솔한 리뷰를 조사·분석하였다. 전반적인 소비자 평가와 커버력, 수분감, 밀착력, 지속력 등 기능적인 요소, 가격, 용량 등에 대해 다섯 가지 제품을 비교하며 문제점을 도출하고 개선방안을 제시한다. This study analyzes the customer responses regarding cushion foundation creams in road shops. With advent of the ubiquitous era, customers not only acquire a variety of information but share their opinions with others. This research investigates factors affecting customer`s buying behavior. Selecting each main product among five brands` cushion foundation creams, I review and analyze the customer responses about the five items uploaded in `Hwahae`, a beauty-related App. This examination includes overall evaluation, price, capacity, and functioning factors (coverage, moisture, and adhesion). Based on the customer feedback, I compare the five cushion foundation creams, summarize controversial issues, and finally provide solutions for each item.

Objective : To obtain the incidence rate of anxiety disorders among the active duty Korean military personnel, who visited the military hospitals from 2011 to 2013, this descriptive epidemiological study was performed. Methods : After acquiring the data for the anxiety disorders from Defense Medical Statistics Information System, the annual incidence rates were analyzed by forces, position status, and specific disease entities. Results : One thousand, nine hundred and thirteen (1,913) active duty male military personnel were diagnosed with any kinds of anxiety disorders in their first visit to the psychiatric outpatient department (OPD). The total OPD visit counts were 7,870 during the same period. Anxiety disorder, NOS was the most frequent disorder, followed by panic disorder. While the incidence rate for anxiety disorder, NOS decreased, panic disorder displayed increasing tendency. Stress-related disorders and obsessive-compulsive disorder were positioned third and fourth, respectively, for the number of first visit and they both showed decreasing tendency in annual incidence rates. Social anxiety disorder, specific phobias, generalized anxiety disorder (GAD) and mixed anxiety-depressive disorder followed next. The annual incidence rates for anxiety disorders showed decreasing tendency, particularly evident in army soldiers. However, naval officers showed higher anxiety disorder incidence rate compared to those of the army and the air forces. Conclusion : Comparing to general population, panic disorder was higher while specific phobias and GAD were lower in the Korean military. It is interesting to observe higher incidence rate for anxiety disorder in naval officers and warrants further evaluation.

Dissolved Air Floatation (DAF) process is one of sewage/waste water carriage methods. Purifying process is makes floating matter from sewage/waste water and air bubble. This study focused on basic research step to purifying industrial sewage using DAF process. For this study, Computational Fluid Dynamics (CFD) method was used. Commercial CFD software ANSYS FLUENT V.14.5 was used for multiphase flow analysis between sewage and air bubble in this study.

High pressure die casting is used in manufacture of the various auto parts due to its excellent productivity compared to any other casting processes. However, it has disadvantage which is difficult to form parts having complex inner shape or under-cut shape by its metal mold. To solve this problem, collapsible cores, which can withstand high pressure and speed of the melt flow on casting and easily be removed after casting, have recently been developed. There are three types of them; sand, salt, and plastic core. The purpose of this study is to develop the sand core which is excellent with respect to productivity, cost, and applicability. In this study, cerabeads was used as core sand and its particle size and resin contents were modified to improve shear strength. In addition, two coating agents were applied to the core and their concentration was adjusted. As the results, the core whose shear strength is above 110kgf/㎠ was obtained, and practical high pressure die casting test using it was performed to verify its applicability.

연구배경: 8주 이상 지속되는 만성 기침의 원인 중 하나인 위식도역류질환는 환자의 약 75%가 증상이 없으며, 진단을 위한 24시간 식도 pH감시가 침습적이고 검사가 어려워 진단 및 치료에 어려움이 있다. 따라서 만성 기침환자 중 후비루증후군 및 기관지 천식이 아닌 환자를 대상으로 양자펌프억제제를 투여하고 치료효과를 관찰하였다. 방법 및 대상: 기침증상이 8주 이상인 만성기침 환자 중 X-ray 소견상 이상이 없고 메타콜린 기관지유발시험상 음성이며, 후비루증후군 치료에 반응이 없었던 40명을 대상으로 하였다. 8주 이상 양자펌프억제제를 투여하였으며 50%이상 기침이 감소한 경우를 부분 반응군, 기침이 거의 소실된 경우를 완전 반응군으로 분류하였다. 결과: 대상자 40명중 29명만이 4주 이상 추적되었으며 이중 26명만이 8주까지 추적 관찰되었다. 29명중 남자가 9명, 여자가 20명이었으며 평균나이는 51세였다. 대상자들에서 기침 이외의 증상은 객담이 12%, 콧물이나 비폐색 등의 코 증상이 있는 환자는 10%, 속쓰림, 소화불량 등의 소화기 증상을 호소하는 환자는 13.4%였다. 29명중 4주간 투여 후 증상의 호전이 없는 환자가 3명(10.3%), 50% 이상의 증상호전을 보이는 환자가 22명(75.9%), 그리고 증상이 거의 소실된 환자가 4명(13.8%)로 약 90%정도의 환자가 기침의 증상호전이 있었다. 8주 투여 후 호전이 없는 환자가 2명(7.4%), 50% 이상 증상호전이 있는 환자가 8명(29.6%), 증상이 거의 소실된 환자가 16명(63.0%)이었다. 결론: 8주이상의 만성기침 환자에서 8주 이상 양자펌프억제제 투여 후 92.6%환자가 증상호전이 있었으며 이중 63%는 거의 소실되었다. 하지만 본 연구는 위약을 통한 대조군이 없는 관계로 그 결과의 해석에 어려움이 있다. 앞으로 좀더 많은 환자를 대상으로 하는 이중맹검시험이 필요할 것으로 생각된다. Background: Recent studies have suggested an association between chronic cough and gastroesophageal reflux. Our study aimed to assess the utility of a proton-pump inhibitor in unexplained chronic cough patients. Methods: Patients with chronic cough of unknown etiology were evaluated using a chest x-ray, methacholine challenge test, and an empirical trial of postnasal drip therapy. After excluding other potential causes of the cough, forty patients were included in the study and treated for 8 weeks with a proton-pump inhibitor. Results: Eleven and three patients in the first and second 4 weeks were lost to follow-up, leaving twenty-six patients finally included in the study. Of these patients, two were unimproved, eight partially responded to the proton-pump inhibitor and sixteen responded completely after the 8 week treatment. Conclusion: We suggest that empirical treatment with a proton pump inhibitor in all patients with persistent cough, which is not secondary to asthma or postnasal drip syndrome, represents a practical and simple approach to this ailment.

Predictive models have recently become increasingly important across various fields. In particular, in clinical research, the main purpose is to build a model that can find risk factors and predict a specific disease. Predictive models can help clinicians make fast and accurate decisions by capturing relationships between multiple factors related dependent variables. Accordingly, this paper describes a predictive model construction method and visualization that can be useful in clinical research. As dependent variables can be divided into continuous, categorical, and survival variables, the concepts and principles of linear, logistic, and cox regression analyses for building predictive models are explained in this paper. In addition, we investigated how to select variables to create an optimal model and how to evaluate the discrimination and calibration of the model. A visualization method that can help interpret according to each regression analysis model is also described. This paper will provide basic knowledge for clinical researchers to more easily build predictive models and evaluate them for practical use.
