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.

저자들은 우상복부 통증과 소화불량을 주소로 내원한 83세 여자 환자에서 국내 최초로 담낭 방선균증을 진단하고 치료 관찰 중으로 이에 문헌고찰과 함께 보고하는 바이다. Actinomycosis is a chronic suppurative and granulomatous disease, characterized by abscess formation, tissue fibrosis, and draining sinuses. Actinomycosis of the gallbladder is very rare and has not yet been reported in Korea. We report a case of actinomycosis of the gallbladder in an 80-year-old women with history of cholelithiasis for 3 years, preoperatively misidentified as gallbladder cancer. Histologic section of the gallbladder showed Gram-positive branching bacilli compatible with actinomyces. After cholecystectomy, the patient received intravenous ampicillin for 4 days, followed by amoxicillin for 4 months thereafter.

Objectives: Community organization is a resident-led movement aimed at creating fundamental social changes in the community by resolving its problems through the organized power of its residents. This study evaluated the effectiveness of health community organization (HCO), Gangwon’s Health-Plus community program, implemented from 2013 to 2019 on residents’ health behaviors.Methods: This study had a before-and-after design using 2011-2019 Korea Community Health Survey data. To compare the 3-year periods before and after HCO implementation, the study targeted areas where the HCO had been implemented for 4 years or longer. Therefore, a total of 4512 individuals from 11 areas with HCO start years from 2013 to 2016 were included. Complex sample multi-logistic regression analysis adjusting for demographic characteristics (sex, age, residential area, income level, education level, and HCO start year) was conducted.Results: HCO implementation was associated with decreased current smoking (adjusted odds ratio [aOR], 0.73; 95% confidence interval [CI], 0.57 to 0.95) and subjective stress recognition (aOR, 0.79; 95% CI, 0.64 to 0.97). Additionally, the HCO was associated with increased walking exercise practice (aOR, 1.39; 95% CI, 1.13 to 1.71), and attempts to control weight (aOR, 1.36; 95% CI, 1.12 to 1.64). No significant negative changes were observed in other health behavior variables.Conclusions: The HCO seems to have contributed to improving community health indicators. In the future, a follow-up study that analyzes only the effectiveness of the HCO through structured quasi-experimental studies will be needed.

목 적 : 원위부 전대뇌 동맥에 발생하는 동맥류는 모동맥의 확보가 힘들고 재출혈 및 수술중 조기출혈의 빈도가 높으며, 익숙치 않은 수술적 접근법이 필요하다든지 하는 몇 가지 독특한 문제점이 있다. 따라서 전대뇌 반구간열 주변의 해부학적 구조물과 박리 시작점에 대한 수술전 지식을 요한다. 저자들은 박리 시작점에 대한 일관된 외부표식자를 이용하여 전두 기저부 대뇌반구간열 접근법 수술을 시행하였고 이를 심부 구조물들에 대한 접근 지표로 삼고자 하였다. 대상 및 방법 : 1995년 11월부터 1999년 6월까지 동맥류경을 결찰한 총 131명의 뇌동맥류파열 환자 중에서 원위부 전대뇌 동맥류 9명에 대하여 혈관조영술, 의무기록지, 수술소견을 통해 임상적, 수술소견을 조사하였다. 결 과 : 원위부 전대뇌동맥류의 빈도는 6.3%였고, 6례에서 뇌량 연변 동맥이 기시하는 뇌량 주위 동맥에서 발생하였고, 3례에서는 전두극동맥이 기시하는 뇌량 주위 동맥에서 발생하였다. 동반된 다른 혈관기형 및 다른 동맥류는 각각 3예에서 발견되었다. 술전 환자 상태는 일반적으로 불량했다. 조기수술은 7예에서 실시되었으며, 전두 기저부 대뇌반구간열 접근법으로 동맥류 결찰을 시행한 경우도 7예였다. 술후 심한 혈관연축과 흡인성 폐렴으로 인한 사망이 각각 1례씩이었으며 그 이외에는 신경학적 소견은 정상이었다. 결 론 : 원위부 전대뇌 동맥류의 조기수술시에 전두 기저부 대뇌반구간열 접근법이 유용하였다. 이 방법으로 뇌견인을 최소화할 수 있었으며 동맥류의 조기파열을 방지할 수 있었다. 저자들은 대뇌반구 간열의 박리 시작점으로 첫번째 교정맥(전두극 정맥)이 상시상 정맥동으로 유출되는 지점을 기준으로 하여 뇌량 및 뇌량 주변부 원위부 전대뇌동맥류에 접근할 수 있었다. Objects : Surgical management of the distal anterior cerebral artery(DACA) aneurysms presents several unique problems to surgeons, such as difficulty in early identification of parent arteries, high incidence of rebleeding and premature rupture, and requirement of unfamiliar approach other than conventional frontotemporal craniotomy. Therefore, preoperative anatomical knowledge of anterior interhemispheric fissure and entry point of dissection is prerequisite. Authors utilized a frontobasal approach for DACA aneurysms by using consistent external landmark for guidance to the deep structure. Materials and Methods : From Nov. 1995 to Jun. 1999, a surgical clipping of DACA aneurysms was carried out in 9 patients among a total 131 patients with intracranial aneurysms. In each case, the clinical and aneurysmal features were carefully reviewed through the angiograms, medical records, and intraoperative findings. Results : The incidence of DACA aneurysms was 6.9% from our series. All cases were arisen from juxtacallosal por-tion ; 6 cases from pericallosal-callosomarginal(PC-CM) junction and 3 from pericallosal-frontopolar(PC-FP) junction. Associated vascular anomalies were noted in 3 cases and multiple aneurysms in 3 cases, respectively. The preoperative clinical grades were generally poor. An early surgery was performed in 7 cases and frontobasal interhemispheric approaches in 7 cases. Postoperatively, two patients died of complications ; one delayed ischemic vasospasm and one aspiration pneumonia but remaining patients recovered well. Conclusion : The frontobasal interhemispheric approach was useful for DACA aneurysms in early surgery. Division of superior sagittal sinus(SSS) enabled a minimal retraction of brain on both sides, and prevention of intraoperative rupture was possible. Authors suggest the frontopolar(first frontal bridging) vein as a constant external landmark for approaching the genu of the corpus callosum and juxtacallosal DACA aneurysms.

The primary goal of video parsing is to accurately detect fast/gradual scene changes to index the video data so that future retrieval may be performed efficiently. Due to the sheer volume of the video data, however, the goal of accurate detection must be met by some real-time (fast) automatic (or at least semi-automatic) video parsing mechanism. For this purpose, I have developed a fast algorithm to detect gradual scene change and also detect camera motions to reduce false positives (falsely declaring a scene-change). In this dissertation, we propose a new approach that detects the change of scene which contains fast motion, zooming, dissolve in AVI video sequence. The proposed scheme adopts the feature matching technique which ALH(Average of Luminance Histogram) in each frame with those in the previous frame. Experimental results show that the proposed method performs better in detection scene changes than other conventional methods.

The purpose of this study was to review for further understanding of the possible mechanisms of free radical formation during exercise and the relation of exercise and exercise induced oxidative stress and the antioxidant system. Acute or chronic strenuous exercise results in excessive production of reactive oxygen species(ROS). This ROS production may lead to lipid peroxidation and protein oxidation in the exercising muscle. Now, the results of study on the role of non-enzymatic defense system was not clear. Further study is necessary to get clear results of antioxidants. But, exercise induced oxidative stress may be reduced by antioxidant ingestion. Therefore, it is necessary to study on proper exercise for reduction of oxidative injury and for efficient practice of intensive exercise by antioxidant administration.

This study aims to provide useful data for designing the outdoor space or planning landscape architecture facilities in apartment housing complex. Primary data were collected by questionnaire survey in Maetan Apartment Complex in Suwon. The questionnaires contain three sets of variables : outdoor environment, landscape architecture facilities, and the respondents' demographic variables. The results are as follows. 1) The apartment residents are using bench or pergola most frequently among the landscape architecture related facilities. 2) The residents are dissatisfied with shortage of parking lots, therefore, more parking area is needed in the apartment complex. 3) The residents expressed considerable concern for trees, however, they pointed out to change some species of trees and need some professional management for them. 4) The variables related landscape architecture facilities were reduced to 6 factors; 'trees', 'bench/pergola', 'excercise/playground', 'pavement', 'lighting facility', 'parking lots'. And 'trees' is perceived the most important factor by the residents. 5) Finally, 'landscape architecture facilities', is most important factor among variables consist of apartment exterior environment.

Transbronchial lung biopsy(TBLB) is a relatively simple and convenient diagnostic tool in solitary pulmonary nodule(SPN) on chest radiograph, which is cannot be diagnosed through routine tests. To investigate the diagnostic value and diagnostic rate of TBLB according to the variable factor, we analyzed 69 patients with radiologically SPN lesion on chest radiograph which was confirmed histologically. A histologic diagnosis of TBLB was made in 47 of 69 patients(68.1%), in which 26 of 37(70.3%) with malignancy and 21 of 32(65.6%) with benign lesion. There were no significant differences in diagnostic yield according to age, sex and location of the lesion. The diagnostic rate tended to increase with the more than 5 pieces to acquired by TBLB. When the size of SPN was less than 3 ㎝, it cannot be diagnosed. In conclusion, TBLB is a diagnostic procedure with good yield and safety, but percutaneous needle aspiration, transbronchial needle aspiration, and bronchial washing fluid cytology may be a complementary procedure to overcome the limitation of TBLB and get higher diagnostic yield for SPN.

김인송,권성균,임형준,이완규 한국수의공중보건학회 2002 예방수의학회지 Vol.26 No.3

Recently, a novel antimicrobial peptide including Buforin II has been emphasized to kill multi-drug resistant bacteria and avoid promoting multi-drug resistance. This study evaluated the efficacy of an antimicrobial peptide (Buforin IIb) on bovine mastitis. Based on the Minimum inhibitory concentration(MIC, 4 g/ml) of Buforin IIb, syringes were made five concentration(MIC×10, ×50, ×100, ×300, and ×500). Thirty three cows(38 quarters) with bovine mastitis were selected using California mastitis test and grouped in dependant on drug concentration and treatment duration. Each group treated by intramammary infusion twice a day for 3 5 days. The milk samples of 5 groups were aseptically collected from quarters at 0, 3, 7 and 14 days, and 2 groups were collected at 0, 5, 9 and 14 days after first treatment. Collected samples were used for bacterial culture and somatic cell count. Bacterial number(log_(10) mean CFU/ml) was decreased in dependant on drug concentration and extending treatment duration. In group D(MIC×300), bacterial number was decreased from 4.59±0.10(day 0) to 2.89±1.37(day 3), 4.04±0.33(day 7), and 4.19 ± 0.10(day 14), respectively(p 0.05). Bacterial number of B2(MIC×50, 5 days treated) is decreased, approximately 10%, than group B1(MIC×50, 3 days treated). Somatic cell count of group D was slightly decreased from 11,100(×10³)(day 0), to 7,386(×10³)(3 day), 6,886(×10³)(day 7), and 9,661(×10³)(day 14). Staphylococcus spp., was the most common isolate, was bacteriologically cured 100% by Buforin IIb treatment. Overall results indicate that Buforin IIb could have possibility to cure bovine mastitis, if higher concentration over experimental concentration were treated with extending treatment duration.
