Objective: The aim of this study was to examine the actual conditions of absence and early leave due to job stress of 4,350 workers in 83 small and medium scale industries, and its relationship to job stress factors using Korean Occupational Stress Scale-Short Form (KOSS-SF). Methods: A structured self-reported questionnaire was used to assess each respondent's Sociodemographics, job stress, experience of absence and early leave due to job stress. Seven KOSS-SF domains of job stress were used. We estimated the relation of absence and early leave due to job stress and job stress factors using logistic regression analyses. Results: Absence or early leave due to job stress occurred in 7% of male workers and 8% of female workers. Multiple regression analysis revealed a significantly positive association job stress-related absence/early leave and job demand, interpersonal conflict, organizational system, lack of rewards and occupational climate. Conclusions: Absence and early leave due to job stress is significantly attributed to organizational System and lack of reward for men, and occupational climate and organizational system for women.

서영광,이지원,이준희,최원철,이의주,고병희,Seo, Young-Kwang,Lee, Ji-Won,Lee, Jun-Hee,Choi, Won-Cheol,Lee, Eui-Ju,Kho, Byung-Hee 사상체질의학회 2010 사상체질의학회지 Vol.22 No.3

1. Objective: Gastric Stuffiness (心下?證) in the Soeumin Taeeum symptomatology (少陰人 太陰病) in Sasang Constitutional Medicine shows an interesting evolutionary process. Originally found in the texts of Sanghanlun (傷寒論), the perspectives regarding the symptoms of Gastric Stuffiness were expanded by many medical scholars and Lee Jema. To comprehend the Jema's concept of Taeeum symptomatology and utilize his prescription clinically, it deserves to study on the Gastric Stuffiness in Donguisuseowon (東醫壽世保元). 2. Methods: Many texts including Sanghanlun (傷寒論) and Dongeuibogam (東醫寶鑑) were reviewed in order to track the evolutionary process concerning the symptoms of Gastric Stuffiness. Also, Lee Jema's works including the different versions of Donguisuseowon (東醫壽世保元) were reviewed to examine the development of Lee's concepts regarding the Gastric Stuffiness in the Soeumin Taeeum symptomatology. 3. Results and Conclusions: 1) Most of the previous concepts on Gastric Stuffiness were generally similar to those found in Sanghanlun, especially in that they addressed Yang deficiency of the middle triple energizeer as the central pathogenic process. 2) Lee Jema's views on the epigastric discomfort in the Soeumin Taeeum symptomatology evoloved over time and culminated in the finalized pathology and therapeutics appearing in his last work, the Shinchuk version of Donguisuseowon (東醫壽世保元). 3) 4 kinds of prescription which invented by Lee Jema to treat the Gastric Stuffiness in the Soeumin Taeeum symptomatology can be matched to the prescription of Sanghanlun respectively. However through evolutionary process of Jema's prescriptions, the indication of them expanded: not only to treat Gastric Stuffiness but to diverse symptoms of Soeumin.

이화평,고동희,이의철 大韓産業醫學會 2009 대한직업환경의학회지 Vol.21 No.1

목적 많은 연구들을 통하여 만성폐쇄성폐질환의 직업성 원인에 대한 역학적 근거들이 제시되고 있지만 산재로 인정받는 경우는 아직 적은 편이다 본 연구에서는 산업안전보건연구원에서 근로복지공단의 의뢰를 받아 시행한 업무관련성 여부에 대한 심의 사례들을 조사하였으며 만성폐쇄성폐질환의 직업성 원인에 대한 근거들을 함께 고찰하여 직업성 만성폐쇄성폐질환에 대한 산업의학적 평가의 시행에 도움을 주고자 하였다 방법 1998년부터 2007년까지 10년간 산업안전보건연구원에서 이루어진 업무상 질병 여부에 대한 심의 기록들을 담고 있는 전산자료에서 만성폐쇄성폐질환을 진단명으로 하는 13건의 사례들을 수집하였다 이들 13건의 기록들로부터 질병명 병력 직업력 흡연력 해당 유해인자 사업장의 작업환경측정 기록 업무관련성 평가에 대한 심의 결과를 파악하였다 결과 총 13건의 사례들 중에서 업무관련성이 높다고 평가된 4건의 사례들은 다음과 같다 1) 도로상 미세 분진과 일반쓰레기 분진에 노출된 비흡연자인 환경미화원 2) 카드뮴 흄에 의해 폐손상을 입은 용접공 3) 방적공장의 면 분진에 의해 발생한 천식이 장기노출에 의해서 만성화되면서 비가역적으로 폐기능이 저하된 공조기 공기필터 관리작업자 4) 개인보호장구와 국소배기장치 없이 작업한 흡연력이 있는 주물공장 사상공 다음의 9건의 사례는 업무관련성이 낮은 것으로 평가되었다 1) 직업성 요인보다는 흡연에 의한 만성폐쇄성폐질환으로 판단된 경우 4례 2) 기존 질환(심한 결핵)의 악화에 의한 질병 발생의 가능성이 큰 경우 1례 3) 잘못 진단된 경우 1례 4) 작업 환경상 유해인자에 대한 노출의 정도가 너무 낮은 경우 2례 5) 유해인자에 노출되기 이전에 이미 발병한 경우 1례 흡연력이 있고 진폐가 없는 사상공의 경우 2006년에는 업무관련성이 낮은 것으로 평가되었으나 2007년에는 높은 것으로 평가되었다 결론 만성폐쇄성폐질환의 산업의학적 평가에 필요한 요소들은 다음과 같다 1) 폐기능 검사와 방사선학적 검사를 통한 만성폐쇄성폐질환의 정확한 진단과 다른 질환들의 배제 2) 해당 유해인자와 질병 발병 사이의 인과관계에 대한 충분한 근거 확보 3) 노출의 정도에 대한 평 가 4) 흡연으로 인한 발병가능성의 평가 산업의는 이러한 요소들을 충분히 고려하여 직업성 여부를 평가하여야한다 또한 환자가 흡연자라고 할지라도 직업성 유해인자에 의한 폐기능의 감소가 평균수명 혹은 건강수명의 실질적인 단축을 가져왔는가라는 문제를 충분히 고려하여 만성폐쇄성폐질환의 직업성 여부를 평가하여야 할 것이다 Objectives To analyse the characteristics of occupational COPD (Chronic obstructive pulmonary disease) cases that were evaluated by the Occupational Safety and Health Research Institute (OSHRI) of the Korea Occupational Safety & Health Agency (KOSHA) Methods Using the OSHRI database from KOSHA we collected 13 cases of occupational COPD that had been evaluated from 1998 to 2007 Results Four cases had been evaluated as occupational COPD 1) a nonsmoking road sweeper exposed to automobile exhaust gases and trash dust 2) an oxygen welding worker exposed to cadmium fumes 3) a cotton mill air conditioner cleaning worker exposed to cotton dust and 4) a foundry grinding worker exposed to dust gases vapors and fumes Nine cases had been evaluated as non-occupational COPD 1) 4 cases in which smoking was determined to be the main cause rather than occupational expo sure, 2) 1 case that was evaluated as another respiratory disease (severe tuberculosis sequelae) 3) 1 case that had been misdiagnosed as COPD 4) 2 cases in which the exposure levels in the workplace environments were too low and 5) 1 case that had developed before the employment Among these 13 cases a shipyard grinding worker had been evaluated in 2006 as having had a low occupational hazard but a similar case (a foundry grinding worker) was evaluated as having had a high hazard in 2007 Conclusions Proper evaluation of occupational COPD demands an accurate diagnosis of COPD itself and also the exclusion of other respiratory diseases that have similar symptoms an investigation of the relevant occupatioonal hazards and the amount of the exposure and a consideration of smoking history The evaluation should also take into account any substantial loss of life due to occupational hazards as well as any disease-free periods

The purpose of this study was to investigate the remodeling process of the streptozotocin-induced diabetic rat's resected condyle. This experiment was performed with male Sprague-Dawly strain rats weighing approximately 250gm, which were rendered diabetic by an intravenous injection of streptozotocin(70 ㎎/㎏ body weight). After condylectomy, experimental rats were serially terminated on the 1st week, the 2nd week, the 3rd week, and the 4th week. The following termination, the mandibles were dissected out to make specimens. Each mandibular condyle was radiographed with Hitex HA-80(Hitex Co., Ltd. Japan). In addition to radiographic observation, the mandibular condyles, further decalcified and embedded in paraffin, were sectioned and stained with Hematoxylin and Eosin, Toluidine blue and Masson's trichrome. The were observed with a light microscope and a polarizing microscope. The results were as follows. 1.Soft X-ray radiograms revealed proliferation of bone after 1 week in both groups. Irregularly repaired bones and dense trabeculae were clearly observed in experimental group. 2.The resected condyles were repaired by intramembraneous and endochondral bone formation in both groups. 3.Bone tissue repair was initiated from the adjacent margin of resected bone, and cartilginous tissues were observed at the top of repaired one in both groups. 4.The number of osteoblasts of experimental group was small, compared with control group. Each osteoblast was small and flap. The thin trabeculae were irregularly formed. 5.Collagens of bone were gradually matured in both groups, but the degree of maturation was lower in experimental group. 6.Fibrous tissues covered the upper parts of repaired bone were densely arranged in the both groups. Conclusively, atrophied osteoblasts, immature collagen of bone, and this and irregular trabeculae which were characterized in the diabetes experimental group showed diabetes disturbed osteoblastic function and caused disturbance of remodeling process of bone.

박철우,황의환,이상래 대한구강악안면방사선학회 2001 Imaging Science in Dentistry Vol.31 No.1

Purpose : To investigate bone and disc configuration on MR images in internal derangement related to age. Materials and methods : MR images of 150 TMJs in 107 patients were analyzed to determine the morphologic changes. Two groups were distinguished to be correlated with age. Group 1 consisted of TMJs that were diagnosed as having anterior disc displacement with reduction (ADDwR), and Group 2 consisted of TMJs that were diagnosed as having anterior disc displacement without reduction (ADDwoR). We assessed the configuration of the articular disc, degree of anterior disc displacement, and osseous changes of TMJs. Results : The third decade (83 of 150 joints) was most frequent in this study. In the ADDwR group biconcave discs was most frequent at all ages except fifth decade, but in the ADDwoR group deformed discs was most frequent at third and forth decades. In the ADDwR group slightly displaced discs was most frequent at all ages, but in the ADDwoR group severely displaced discs was most frequent at second decade, and the degree of disc displacement was increased with aging over 30 years of age. TM joints showed osseous changes in 17% of the ADDwR group, and in 30% of the ADDwoR group. MR findings of osseous changes of the TMJ were not found to be significantly correlated with age. Conclusion : The prevalence of deformation of disc, displacement of disc, and osseous changes of TMJ was higher in the ADDwoR group than in the ADDwR group. MR findings of disc configuration and degree of disc displacement were found to be correlated with age.(Korean J Oral Maxillofac Radiol 2001;31:9-16)
