Purpose: Syncope is a common clinical problem. However,diagnosis of the cause of syncope is not simple due to a wide variety of forms of syncope. The aim of this study was to assess current diagnostic methods and the associated medical costs which accompany the evaluation of patients suffering syncope who admitted to an emergency department (ED). Methods: This study is a prospective, observational, single center study. Patients included in the study visited the ED of a single, tertiary hospital between January and December 2009, and were diagnosed with syncope. We investigated the diagnostic yields (DY) for the tests that were employed and evaluated factors related to medical costs. Results: A total of 124 patients were enrolled in this study. Blood tests, chest radiography, postural blood pressure (BP) measurement and computerized tomography of the brain were performed in over 60% of cases, but DY for each of these tests was less than 3%, except for postural BP measurement (7.4%). The test which demonstrated a relatively high DY was the head-up tilt test (68.1%). The ratio of the cost of each test among the total medical costs required by all patients (constituent ratio) was highest for brain imaging tests (12.2%). The total cost of syncope evaluation per patient was 1,454,000±2,865,000 won. Factors including hospital admission and diagnosis of cardiac syncope resulted in significantly higher total medical costs for those patients. Conclusion: Among the tests performed in the ED for syncope evaluation, blood tests, chest x-ray and brain imaging tests were commonly used but resulted in relatively low diagnostic yield. Independent factors which increased medical costs were hospital admission and diagnosis of cardiac syncope.

윤희 한국미용학회 2018 한국미용학회지 Vol.24 No.3

The excellent service quality is one of important competitiveness factors to improve direct and indirect cost efficiencies in the service industry, and reduce loss expenses of customers. In this reality, there are unsatisfactory service quality studies for makeup shop, and there are no precedent studies on employees' service quality in makeup shop. So this study is intended to look into the effects of employees' service quality on customer satisfaction and word-of-mouth intention in makeup shop, and provide data that help their service quality improvement, customer satisfaction and word-of-mouth intention in makeup shop. The SPSS v. 21.0 was used for data analysis. Data were verified within the .05 significance level through frequency analysis, descriptive statistical analysis, correlation analysis, factor analysis, reliability analysis, Cronbach' coefficient α calculation, and linear regression analysis. A survey was carried out to customers visiting makeup shops in Gwangju. A 9-point Likert scale was used to analyze 458 questionnaires. This study is mainly composed of the importance of employees' service quality in makeup shop, the precedent studies on customer satisfaction and word-of-mouth intention, the design of study and employees' service quality analysis. The findings showed that employees' service quality in makeup shop had an effect on customer satisfaction and word-of-mouth intention, and customer satisfaction on word-of-mouth intention. Consequently, a makeup shop owner has to run systematic service education for improving employees' service quality, and go ahead with their better customer service in his/her own makeup shop.

가스건 시험에서 원추형 충격자의 충격 감가속도 예측에 관한 전산해석적 연구

윤희,오종수,정명숙 한국전산구조공학회 2019 한국전산구조공학회논문집 Vol.32 No.5

본 논문에서는 가스건 시험에서 원충격자의 충격 감가속도 예측에 관한 전산해석적 연구를 수행하였다. 무기체계 개발에 있어서, 가스건 시험을 통한 수만 G 이상에서의 내고충격성능에 대한 검증은 필요하다. 시험품이 받는 충격 감가속도는 버드조립체의 형상, 무게, 비행 속도 등 여러 변수에 의존하기 때문에 충격 감가속도를 생성시키는 적합한 시험조건을 찾는 것은 매우 중요하다. 하지만, 시험을 통해 기본적인 데이터를 구축하는 것은 경제적인 측면에서 비효율적이기 때문에 전산해석적 기법을 확보하여야 한다. 이에 본 연구에서는 130mm 가스건 시험을 바탕으로 획득한 데이터를 기반으로 하여 Explicit 코드를 사용하는 ANSYS AUTODYN을 활용하여 전산해석을 수행하였다. 전산해석을 통해, 시간에 따른 시험품의 동적거동현상 뿐만 아니라 전산해석결과를 시험결과와의 비교 및 분석을 함으로써 검증을 수행하였다. In this study, a numerical investigation is conducted for the shock deceleration prediction of a conical impactor in gas-gun tests. With the development of weapon systems, gas-gun tests are required to validate the survivability and structural reliability of devices under test (DUT) in high-G shock environments, such as those over ten thousand Gs or more. As shock endurance is highly influenced by various bird parameters, such as mass, velocity, and pressure, it is important to determine the appropriate test conditions to generate a high-G shock environment. However, experimental repetitive studies are inefficient to validate test conditions in terms of economic aspects. Therefore, a numerical technique is required to replace experimental gas-gun tests. Here, a numerical investigation is conducted with ANSYS AUTODYN using explicit code. Through this investigation, the dynamic behavior of DUT is presented. In addition, the results of numerical studies are verified through a comparison with the experimental results of a gas-gun test.

윤희,전병우,김호중,유홍석,박성범 대한의학회 2017 Journal of Korean medical science Vol.32 No.2

Adenovirus (AdV) can cause severe pneumonia in non-immunocompromised host, but limited data exist on the distinctive characteristics of AdV pneumonia in non-immunocompromised patients. We evaluated distinctive clinico-laboratory and radiological characteristics and outcomes of AdV pneumonia (n = 179), compared with non-AdV pneumonia (n = 188) in Korean military personnel between 2012 and 2016. AdV pneumonia patients had a higher rate of consolidation with ground-glass opacity (101/152) in lobar distribution (89/152) on computed tomography (CT) (P < 0.001). Laboratory findings showed a higher incidence of unusual blood profiles such as leukopenia (55/179, P < 0.001) or thrombocytopenia (100/179, P < 0.001). The patients had more systemic symptoms such as myalgia (82/179, P = 0.001) or diarrhea (23/179, P < 0.001), compared with non-AdV pneumonia patients. Bacterial co-infection was identified in 28.5% of AdV pneumonia. Most of the AdV isolates typed (69/72, 95.8%) were AdV-55. Patients with a pneumonia severity index ≥ class III were more commonly observed in AdV pneumonia patients compared with non-AdV pneumonia patients (11.2% vs. 2.1%, P < 0.001), and time to clinical stabilization from admission was longer in the AdV pneumonia patients compared with the non-AdV pneumonia patients (3.8 vs. 2.6 days, P < 0.001). Mechanical ventilation (n = 6) was only required in AdV pneumonia patients, one of whom died due to AdV-55. Our data showed that AdV pneumonia in non-immunocompromised patients had distinct characteristics and most of the isolates typed in our study were AdV-55. It is suggested that AdV-55 is an important pathogen of pneumonia in Korean military personnel.

Inulin Increases Glucose Transport in C2C12 Myotubes and HepG2 Cells via Activation of AMP-Activated Protein Kinase and Phosphatidylinositol 3-Kinase Pathways

윤희,Jong Hwa Lee,Chang Eun Park/Min-Jung Kim,김민정,Byung-Il Min,배현수,최원재,강인숙,Sung-Soo Kim,하주헌 한국식품영양과학회 2009 Journal of medicinal food Vol.12 No.5

Inulin, a naturally occurring, functional food ingredient found in various edible plants, has been reported to exert potential health benefits, including decreased risk of colonic diseases, non–insulin-dependent diabetes, obesity, osteoporosis, and cancer. However, the mechanism of the antidiabetic activity of inulin has not yet been elucidated. In this study, we showed that inulin increased the uptake of glucose in C2C12 myotubes, which was associated with both AMP-activated protein kinase (AMPK) and phosphatidylinositol 3-kinase (PI3-K) signaling pathways, but both of these pathways appeared to transmit their signals in an independent manner. Moreover, we found that inulin was able to increase the uptake of glucose in C2C12 myotubes in which insulin resistance was induced by exposing cells to high glucose concentrations. The identical effects of inulin were also observed in HepG2 hepatoma cells. Collectively, we report the antidiabetic activity of inulin and further demonstrate for the first time that such activity is associated with AMPK and PI3-K activation.
