목적: 이 연구는 전국 규모의 조사 연구에서 수집된 자료 중 사무직 근로자들을 대상으로,사회인구학적 특성,직업 특성,건강행태,직무 스트레스와 피로수준 간의 관련성을 분석하는 데 있다. 방법:‘한국인 직무스트레스 측정도구의 표준화 전국 조사연구National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002∼2004)’를 위해 2002년 5월 1일부터 2003년 5윌 30일 까지 수행되었으며,전국의 사업장에 근무하는 근로자 30,146명(남자: 84%,여자: 16%) 중 사무직 근로자 4,457명(남자: 68.9%,여자 31.1%)을 연구 대상으로 하였다. 자료수집방법은 사업장을 방문하여 보건 및 안전관리자 등에게 연구의 취지를 알린 후 설문조사에 대한 협조를 구하고 응답자 직접 기입법을 이용 하였으며,사회인구학적 특성,직업적 특성,건강관련 요인,KOSS-SF를 이용한 7개의 직무 스트레스 요인,그리고 MFS를 이용하여 피로 수준에 영향을 주는 요인에 대해 분석하였다. 결과: 일반적 특성,작업관련 특성,건강행태관련 특성 및 직무 스트레스 요인이 근로자들의 피로와 강한 관련성이 있음이 입증되었으며,특히 직무 스트레스의 하부 요인 중에서도 피로와 관련성을 보이는 요인이 남녀별로 다소 상이 하게 관련된다는 것을 발견할 수 있었다. 남자의 경우는 직무 스트레스의 하부 영역 중 직무 요구도,직무 불안정성,보상부적절 등이 영향력이 높은 주요 직무 스트레스 요인이었던 반면,여자는 직무 요구도,보상부적절,직장문화가 주요한 직무 스트레스 요인이었다. 결론: 직장인 피로가 갖는 보건학적 의학적 경제학적 중요성을 감안할 때,조직의 생산성 향상과 근로자 개개인의 삶의 질 향상 및 건강증진을 위해선 직무 스트레스 관리 프로그램이 절실히 요청된다고 볼 수 있다. Background & Objectives: A growing body of research has documented that occupational stress is closely associated with increased risk of fatigue. This study was conducted in an effort to assess the relationship of occupational stress to self-perceived fatigue among Korean white collar employees. Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project, 2002-2004). Among them, a total of 4,502 white collar employees were recruited. A structured questionnaire was employed to evaluate the participants' sociodemographics, job-related factors, health-related behaviors, occupational stress, and self-perceived fatigue. Occupational stress and self-perceived fatigue were assessed using the Korean Occupational Stress ScaleShort form (KOSS-SF) and the Multidimensional Fatigue Scale (MFS), respectively. Results: In logistic regression analyses, occupational stress was associated with an increased risk of fatigue, and some domains of occupational stress had different effects on fatigue by gender (job demand, job insecurity, and lack of reward for men, job demand, lack of reward, and discomfort in occupational climate for women), which indicates that occupational stress may perform a slightly different role in increasing the risk of fatigue by gender. Conclusion: The results of this study suggest that occupational stress is a determinant predictor of self-perceived fatigue. Thus, a stress management program for the reduction of occupational stress, and the promotion of white collar worker's health and quality of life is strongly recommended. Some limitations of this study and considerations for future studies were also discussed.

This investigation is designed to illustrate the clinical features '||'&'||' preoperative diagnosis, surgical role in the management of pulmonary aspergilloma, '||'&'||' compare with the previous study. We reviewed 42 cases of surgically treated pulmonary aspergillosis from Jan. 1984 to July 1992. The peak age incidence laid in the 2nd '||'&'||' 3rd decade of 25 cases[59.5%]. The 41 cases[97.6%] had a history of treatment with anti-tuberculous drugs under impression of pulmonary tuberculosis. The most common complaint was hemoptysis in 28 cases[66.7%]. The 21 cases showed so called "Air-meniscus sign" on the preoperative chest X-ray. As a preoperative diagnostic modality, the positivity was 30.0%, 57.8%, 88.5% on the fungus culture of sputum for Aspergillus, Chest CT, serum immunodiffusion test for A. fumigatus, respectively. The 37 cases[88.1%] can be diagnosed as pulmonary aspergillosis pre-operatively by any diagnostic method. The anatomical location of aspergilloma was mainly upper lobe in 17 cases[40.5%] '||'&'||' the majority of cases were managed by lobectomy. The postoperative pathologic findings showed that 18 cases[41.0%] were combined with tuberculosis '||'&'||' 15 cases[34.1%] were not combined with any other disease[Pr imary Aspergillosis]. The 6 cases showed postoperative empyema including 4 cases of bronchopleural fistula, 3 cases showed postoperative bleeding. One case was died postoperatively due to respiratory failure. In conclusion, when the patient who has longstanding history fo pulmonary tuberculosis '||'&'||' hemoptysis, must be suspected fungal super infection. The resectional surgery is the treatment of choice for symptomatic localized disease. And compare with the previous study, preop. chest CT '||'&'||' immunodiffusion test were more commonly available '||'&'||' showed high positivity.

Alterations in thyroid function test results are frequently seen in patients with nonthyroidal illness & correlate with the severity of the illness & prognosis. We studied thyroid hormone changes in 14 patients received cardiopulmonary bypass[CPB]. All patients were biochemical euthyroidism preoperatively. TSH[Thyroid Stimulating Hormone] level reached its nadir[0.46 $\pm$ 0.11 ulU/ml, P<0.0005] at 12 hours after the start of CPB & showed elevating pattern to the preoperative level thereafter. FT4[Free Thyroxine] reached to its nadir[10.16$\pm$ 1.17 pmol/L, P<0.01] at POD[Post Operative Day] #4 & reached to the preoperative level at POD #7. Mean serum TSH & FT4 concentration were within normal limits[P>0.25] during CPB & thereafter. TT3[Total Triiodothyronine] reached to its nadir[38.6 $\pm$ 8.4 ng/dl, P<0.001] at 30 minutes after the start of CPB & remained low[P<0.05] throughout the study period. The patients whose recovery was uneventful[Group I] had higher serum TSH, TT3 levels[P<0.05] than who had complications or died[Group II]. Group I showed the elevating pattern of TSH, TT3 at POD #4, but Group II failed to show such elevating pattern. In Group I, FT4 was within normal limits[P>0.5] throughout the study period, and also within normal limits[P>0.1] in Group II.

We experienced 6 cases of primary cardiac tumor, all received operation for removal of tumor. Mean age was 43.8 years-old ranging from 17 years-old to 66 years-old. Five cases were female, one case was male. Five cases were benign, myxoma, all located within left atrium. One case was malignant, angiosarcoma within right atrium. All patient showed cardiac manifestations. One case was in NYHA functional class II, two were in III, three were in IV. Four patients showed constitutional symptoms, but no one showed evidence of embolic phenomenon. All case of myxoma showed cardiomegaly except one malignancy. Only one case was regular sinus rhythm, three were sinus tachycardia 8z two were atrial fibrillation. The most common site of tumor origin was fossa ovalis limbus[four of all]. Two of five myxomas received emergency operation, one patient died postoperatively. Lived four patients showed no evidence of recurrence[mean follow-up, 3,5 years], but one patient has Grade II /IV mitral regurgitation & in OPD follow-up now, One malignant case, 17 years-old cerebral palsy female, was angiosarcoma occupied most of right atrial chamber originated from anterior wall of right atrium, received emergency operation which was removal of mass & reconstruction of right atrium with artificial pericardial patch. This patient died on postoperative 36th day due to persistent LCOS[low cardiac output syndrome] with combined sepsis.

Among elevn consecutive cases having undergone Completion Pueumonectomy[CP]between 1958 and Aug. 1993 at the Dep. of Thoracic & Cardiovascular Surgery in National Medical Center. The patient`s mean age was 43 years[range 28 yrs, to 68yrs.],& they consisted with 10 males and 1 female. The indications for CP were benign diseases in 9 cases & 2 cases of lung cancer. The mean interval between the first operation & CP was 62.3 months[from 17 days to 288 months]. The several special intraoperative procedures such as intrapericardial pulmonary vesselsdivision & suture ligation, reinforcement of bronchial stumpmargin, & applied the Fibrin glue & hemostatics. The mean intra operative bleeding was 3582ml.[1500ml. to 6500ml.] The post orerative complication were developed in 5 cases[45.5%] they were empyema with BPF in 2 cases, empyema in 2 cases, & 1 case of repiratoy insufficiency which leading to death. We concluded that the C P noted high morbidity & mortality compared with ordinary first pulmonary resectional surgery. But, it will be a challenge to improved the morbidity because of increasing trend of completion pneumonectomy in a furture time.
