Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

A Study on an Independent Steering & Driving Control Algorithm for 6WS/6WD Vehicles

Joo-Young Choi,Dong-Hyung Kim,Chang-Jun Kim,Young-Ryul Kim,Sang-Ho Kim5,Chang-Soo Han 제어로봇시스템학회 2010 제어로봇시스템학회 국제학술대회 논문집 Vol.2010 No.10

Skid-steered vehicles are favored for military use in off-road operations because of their high maneuverability and mobility on extreme terrains and obstacles. There is a trend towards transforming steered tracked vehicles to skid-steered wheel vehicles for high speed at the expense of reduced mobility. Skid-steered vehicles turn by generating different longitudinal forces at the tires due to the application of different torques to the wheels on the opposite side of the vehicle. Conventional vehicles, however, cannot generate an opposite driving force at each side wheel. Using an independent steering and driving system, six-wheel vehicles can show better performance than conventional vehicles. Hybrid steering is a combination of skid steering in the load velocity and the steered wheel system at high speed. This steering enhances maneuverability under low speed and stability at high speed. This paper describes a 6WS/6WD vehicle for hybrid steering in three parts: the Vehicle Model, the Control Algorithm for Hybrid Steering, and a Simulation. First, the vehicle model is an application of the TruckSim software for 6WS and 6WD. Second, the hybrid steering control algorithm describes the optimum tire force distribution method for energy savings. The last is simulation and verification.

목적 : TDI는 직업성천식을 일으키는 대표적인 물질로 알려져 있다. 과거 TDI에 노출된 작업자들의 천식 발생률을 5~6%가량 보고하였고, 국내에서도 2-20%에 이르는 유병율을 보고한바 있다. 작업환경이 많이 개선되고, 노출량이 감소된 최근에도 TDI에 의한 직업성천식에 대한 보고가 많이 이루어지고 있어, 이에 대한 적극적인 조사와 진단과정을 통해 유병율을 구하고 질병발생의 변화양상을 파악해 보고자 하였다. 방법 : 인천지역에서 특수건강진단을 수행하는 2개 기관의 TDI 노출 근로자 400여명 중, 사업장의 규모가 50인 이상이며 사업주가 연구진행을 허락한 사업장에서 근무하는 근로자 중 직접적으로 TDI에 노출되는 작업에 종사하는 근로자 170명을 연구대상으로 하였다. 이들에 대해 설문지와 산업의학의사의 면담을 통한 작업관련성 평가를 근거로 정밀대상자를 선정하고 이들에 대해 메타콜린 유발시험, TDI 유발시험 등을 수행하여 직업성천식을 확인하였다. 결과 : 설문조사 결과 11명이 직업과 관련하여 천식증상을 보이는 것으로 나타났고(6.9%), 이중 7명에서 메타콜린 유발검사 양성소견을 보였다. TDI에 의한 특이유발시험 결과 1명에서 양성반응이 나타나, 이 집단에서 TDI에 의한 직업성천식의 유병율은 0.58%였다. 결론 : 과거 국내연구에서 TDI에 의한 직업성천식의 유병율이 2~20%에 이르렀던 데 비해, 본 연구에서는 0.58%로 나타났다. 이는 국외 논문에서도 나타나는 경향으로 작업장 노출량 감소로 점차 발생률이 감소하는 양상을 보이고 있다. 그러나 이미 증상이 나타난 근로자들이 부서를 옮기거나, 직장을 그만둠으로 인해 그 유병율이 과소평가되었을 가능성도 있다고 판단된다. Objecdives: This study was carried out to estimate the prevalence of isocyanate-induced occupational asthma in toluene diisocyanate (TDI) exposed workers. Methods: We examined 170 workers who had been directly exposed to TDI through a medical questionnaire, physical examination, and pulmonary function test. Based on screening examination, workers with suspected occupational asthma were selected for further evaluation such as methacholine and TDI challenge tests. Results: Eleven (6.9%) among 170 workers complained of symptoms of occupational asthma. and 7 among these 11 symptomatic workers showed positive responses to the methacholine challenge test (4.1 %). One spray painter was confirmed as having the TDI induced occupational asthma following a positive response to TDI challenge test. Conclusions: The prevalence of TDI-induced asthma was at 0.58% was lower than that for former studies (2-20%). Improved workplace environment, lower level of TDI exposure compared to the past, and the healthy workers effect may have contributed to this low rate of asthma prevalence in workers with TDI exposure.

Dong‑Jun Lee,Taesoo Kwon,Chang‑Kug Kim,Young‑Joo Seol,Dong‑Suk Park,Tae‑Ho Lee,Byung‑Ohg Ahn 한국유전학회 2020 Genes & Genomics Vol.42 No.11

Background Sequence variations such as single nucleotide polymorphisms are markers for genetic diseases and breeding. Therefore, identifying sequence variations is one of the main objectives of several genome projects. Although most genomeproject consortiums provide standard operation procedures for sequence variation detection methods, there may be differencesin the results because of human selection or error. Objective To standardize the procedure for sequence variation detection and help researchers who are not formally trainedin bioinformatics, we developed the NGS_SNPAnalyzer, a desktop software and fully automated graphical pipeline. Methods The NGS_SNPAnalyzer is implemented using JavaFX (version 1.8); therefore, it is not limited to any operatingsystem (OS). The tools employed in the NGS_SNPAnalyzer were compiled on Microsoft Windows (version 7, 10) andUbuntu Linux (version 16.04, 17.0.4). Results The NGS_SNPAnalyzer not only includes the functionalities for variant calling and annotation but also providesquality control, mapping, and filtering details to support all procedures from next-generation sequencing (NGS) data to variantvisualization. It can be executed using pre-set pipelines and options and customized via user-specified options. Additionally,the NGS_SNPAnalyzer provides a user-friendly graphical interface and can be installed on any OS that supports JAVA. Conclusions Although there are several pipelines and visualization tools available for NGS data analysis, we developedthe NGS_SNPAnalyzer to provide the user with an easy-to-use interface. The benchmark test results indicate that theNGS_SNPAnayzer achieves better performance than other open source tools.

만성 B형 간염환자에서 인터페론 치료 후 간 조직검사 소견의 변화와 Tumor Necrosis Factor의 임상적 의의

김홍수,윤동진,김은주,정일권,박상흠,이문호,김선주 순천향의학연구소 2000 Journal of Soonchunhyang Medical Science Vol.6 No.2

Background: Interferon has been widely used in the treatment of chronic hepatitis B, but its effectiveness is debatable. The clinical indices as the loss of HBeAg, HBV DNA, and improvement of liver function are applicated to identify the effectiveness of interferon therapy, but the mechanism of hepatohistological change is not well known. We investigated the changes of histologic finding and plasma tumor necrosis factor(TNF) in the patients with chronic hepatitis B after treatment with interferon-alpha. Methods: 11 patients with chronic hepatitis B who had treated by interferon-alpha were enrolled for this study. Liver biopsy was done before and after treatment of interferon and plasma TNF was evaluated at the same time. A semiquantitative study using a histologic scoring system was applied on pre and post liver biopsy specimens and the changes of HBeAg and HBV DNA were also evaluated. Results: Among subjects, the response group, recurrence group, and non-response group based on serologic response with clearance of HbeAg were6, 3, and 2 patients, respectively. The changes of serum ALT level and HBV DNA titer on pre and post therapy decreased significantly in the response group. The change of mean plasma TNF level in the response group decreased insignificantly to 19.4 from 19.9. The histological improvements of grading and staging were shown 4 patients in the response group. Conclusions: Serologic response with clearance of HBeAg was associated with histolofical improvement. The loss of HBsAg in the serum was significant indicator of reduction in the amount of HBV core antigen and HBV surface antigen in the hepatocytes. Plasma TNF level was not associated with response of interferon-alpha therapy and histologic activity.
