  • 27 shipyard welders were diagnosed as pneumoconiosis and suspected pneumoconiosis(1976-1988) by chest radiographs and were observed over three years. 27 welders were divided into three groups by the state of exposure to welding fume i.e. cessation, decresase or continuity of exposure. And we observed the changing pattern of the chest radiographs of 27 welders with the passage of time. The results were as follows; 1. Grour I (ceased exposure to welding fume) were 10 cases(3 cases: suspected pneumoconiosis,7 cases: pneumoconiosis). Chest radiographs of all cases were improved. The shape and size of small opacities was improved in 6 cases(85.7%) and did not changed in 1 case(14.3%) out of 7 pneumoconiosis welders. 2. Group II (decreased exposure to welding fume) were S cases(2 cases: suspected pneumoconiosis, 3 cases: pneumoconiosis). Chest radiographs were progressed in 2 cases(40%), did not changed in 1 case(20%), were improved in 2 cases(40%) out of 5 cases. The shape and size of small opacities was progressed in 1 case(33.3%) and was improved in 2 cases(66.7%) out of 3 pneumoconiosis welders. 3. Group III(continued expoxsure to welding fume) were 12 cases(1 case: suspected pneumoconiosis, 11 cases: pneumoconiosis). Chest radiographs were progressed in 9 cases(75%), did not changed in 3 cases(25%) out of 12 cases. The shape and size of small opacities was progressed in 1 case(9.1%) and did not changed in 10 cases(90.9%) out of 11 pneumoconiosis welders. 4. The average duration for development into suspected pneumoconiosis was 6.6 years and for progression of each one category after that was 2.2 years(p<0.01). The radiological appearance of pneumoconiosis had disappeared or decreased after cessation of exposure to the welding fume. So that, early detection and control e.g., change of department of pneumoconiosis of welders by screening program will be important for medical surveillance of welders.

  • 노인의 자가 운전은 노인의 활동범위를 확대시키고 사회참여의 기회를 제공한다는 점에서 노년기에 의미있는 활동을 위한 필요조건이다. 운전은 신체적, 인지적, 감각적 기능의 통합을 요구하며 인적, 심리적 요인의 영향을 받는 매우 복잡한 활동이기 때문에 노화로 인한 기능저하는 고령운전자의 운전수행능력에 영향을 준다. 본 연구는 체계적인 문헌고찰을 통해 고령운전자의 운전중단이나 사고위험 증가에 영향을 미치는 요소가 무엇인지 확인하는데 목적을 두고 있다. 문헌 검색을 위해 사용된 온라인 데이터베이스는 MEDLINE, Excerpta Medica database(EMBASE), Cochrane Library, KoreaMed, Pubmed 였으며, 사용된 MeSH용어는 'aged', 'aging', 'automobile driving', 'age factors'였다. 2007년 1월부터 2017년 9월까지 발표된 문헌을 검색하여 1,458건의 결과를 얻었으며 선정기준에 부합하는 18편의 연구를 추출하였다. 결과에서는 운전중단 요소 및 사용된 측정도구와 운전중단에 따른 인구학적 특성을 분석하였다. 운전중단 영역 중 신체적 영역에서 유의미한 결과를 나타내는 측정도구가 11개로 가장 높은 빈도를 보였으며, 운전중단과 관련된 요소에서는 정보처리속도, 수행기능, 운전능력, 운전습관이 각 4개씩으로 운전중단과 유의미한 결과를 나타냈다. 인구학적 특성에서는 성별과 연령에 따라 운전중단과 관련이 있었다. 본 연구결과는 노화로 인한 기능저하가 운전수행에 미치는 영향을 분석하여 운전중단 예측요소들을 파악하고 노인의 안전한 운전수행을 위한 대책 마련의 필요성을 강조한다. 또한 노인의 다양한 운전중단 예측요소를 바탕으로 개별적인 교육프로그램 등의 서비스를 체계적으로 구축할 필요성을 제시한다.

  • 본 연구에서는 2015년 담배가격 인상정책 전후 청소년 흡연율 변화, 금연시도율 변화 등에 대해 살펴보고자 하였다. 이에 본 연구는 총 800개교의 중학생 및 고등학생을 대상으로 조사를 실시한 제9차(2013년), 제10차(2014년), 제11차(2015년) 청소년건강행태온라인 조사 원시자료를 이용하여 청소년들의 일반적 특성, 정신건강 및 주관적 학업성적, 음주 및 흡연관련 특성에 따른 담배가격 인상 전후 흡연율 변화 및 금연시도율, 금연시도이유 중 '담배값이 너무 비싸서' 선택률, 흡연량 변화를 분석하였다. 본 연구에서 전체 청소년의 현재 흡연율은 2013년 9.7%에서 2014년 9.2%로 감소하는 모습을 보였고, 담배가격 인상 후인 2015년 흡연율은 7.8%로 전년대비 15.2% 감소율을 보여 담배가격 인상 전보다 큰 폭으로 감소한 것으로 나타났다. 이러한 결과들을 통해 담배가격 인상정책이 청소년 흡연율을 감소시키는데 매우 효과적일 뿐만 아니라 금연동기 및 흡연 예방에도 매우 효과적이라는 것을 확인할 수 있었다. 청소년기 흡연자의 대다수가 성인기 흡연자로 이어진다는 점에서 청소년기의 흡연 예방 및 금연 유도는 매우 중요하다. 향후 흡연실을 허용하지 않는 완전 금연구역의 확대와 담배 광고, 판촉, 후원에 대한 포괄적 금지는 시급히 추진되어야 하며 이미 근거를 바탕으로 작성된 WHO FCTC의 각조약을 충실히 이행할때 금연효과를 극대화 할 수 있을 것이라 사료된다.

  • Background: E-cigarettes are steadily gaining popularity in Korea. However, the characteristics of e-cigarette smokers, especially nicotine dependence and stress susceptibility, have not been evaluated in comparison to those of nonsmokers or combustible cigarette smokers in Korea. Methods: In this study, 28,059 participants from the Korea National Health and Nutrition Examination Survey (2013-2017) were classified into the following three groups: non-smokers, smokers (current smokers and ex-smokers of combustible cigarettes only), and e-smokers (current smokers and ex-smokers of e-cigarettes regardless of combustible cigarette use). Results: Among the participants, 16,980 (60.5%), 9,247 (33.0%), and 1,832 (6.4%) subjects were non-smokers, smokers, and e-smokers, respectively. E-smokers were younger, more educated, and had a higher household income than non-smokers or smokers. The number of e-smokers who smoked within 5 minutes of waking up (31.5% vs. 19.8%, p<0.001) and who planned to quit smoking within 6 months (39.1% vs. 35.7%, p<0.05) was greater than that of smokers. E-smokers perceived stress as "very much" (7.0% vs. 4.4%, p<0.001) and "a lot" (29.1% vs. 20.5%, p<0.001) compared to non-smokers. Suicidal ideation (6.5% vs. 4.7%, p<0.001), plans (2.4% vs. 1.3%, p<0.001), and attempts (1.1% vs. 0.5%, p<0.001) were higher in e-smokers than in non-smokers. Depressive episodes in 1 year (14.2% vs. 11.4%, p<0.05) and suicidal plans (2.4% vs. 1.8%, p<0.05) were more frequent among e-smokers than among smokers. Conclusion: E-smokers were younger, more educated, and had a higher income, but they were more dependent on nicotine and susceptible to stress than non-smokers and smokers. Smoking cessation counseling should be tailored according to the characteristics of e-smokers.

  • Parenchymal pulmonary endometriosis is the likely cause in patients with hemoptysis, dyspnea, or chest pain during menstruation. Embolization of endometrial tissue from the uterus to the lungs via the pulmonary arteries has been proposed for the mechanism of the development of parenchymal pulmonary endometriosis. This is a report of a woman with catamenial hemoptysis which was responded successfully to danazol therapy; however, hemoptysis resumed after cessation of therapy. The patient was subsequently treated with danazol again because she refused surgical treatments.

  • A stress jump, defined as the instantaneous gain or loss of stress on startup or cessation of a deformation, has been predicted by various models and has relatively recently been experimentally observed. In 1993, Liang and Mackay measured shear stress jump data of xanthan gum solutions, and in 1996, Orr and Sridhar reported extensional stress jump data of Boger fluids. Shear stress jumps of suspensions and liquid crystal polymers have also been observed. In this contribution, experimental work as well as a variety of theoretical models, which are able to predict a stress jump, are reviewed.
