Objectives: This study was performed to examine the factors affecting re-smoking in male workers. Methods: A self-administrated questionnaire survey was conducted during April 2003 to examine the smoking state of 1,154 employees of a company that launched a smoking cessation campaign in1998. Five hundred and eighty seven persons, who had stopped smoking for at least one week, were selected as the final study subjects. This study collected data on smoking cessation success or failure for 6 months, and looked at the factors having an effect on re-smoking within this period. This study employed the Health Belief Model as its theoretical basis. Results: The re-smoking rate of the 587 study subjects who had stopped smoking for at least one week was 44.8% within the 6 month period. In a simple analysis, the re-smoking rates were higher in workers with a low age, on day and night shifts, blue collar, of a low rank, where this was their second attempt at smoking cessation and for those with a shorter job duration (p<0.05). Of the cues to action variables in the Heath Belief Model, re-smoking was significantly related with the perceived susceptibility factor, economic advantages of smoking cessation among the perceived benefits factor, the degree of cessation trial's barrier of the perceived barriers factor, smoking symptom experience, recognition of the degree of harmfulness of environmental tobacco smoke and the existence of chronic disease due to smoking (p<0.05). In the multiple logistic regression analysis for re-smoking, the significant variables were age, perceived susceptibility for disease, economic advantages due to smoking cessation, the perceived barrier for smoking cessation, recognition on the degree of harmfulness of environmental tobacco smoke, the existence of chronic disease due to smoking and the number of attempts at smoking cessation (p<0.05). Conclusion: From the result of this study, for an effective smoking ban policy within the work place, health education that improves the knowledge of the adverse health effects of smoking and the harmfulness of environmental tobacco smoke will be required, as well as counter plans to reduce the barriers for smoking cessation.

이중정,양진훈,,황인섭 大韓産業醫學會 2006 대한직업환경의학회지 Vol.18 No.2

비닐하우스 농사자와 일반 농사자의 농부증 유병률의 차이를 비교하고, 농부증의 유병과 관련된 요인들을 규명하기 위하여, 2003년부터 2005년까지 경상북도 고령군과 안동시 지역을 대상으로 인구학적 특성 및 생활습관력, 농부증 증상 유무, 그리고 농작업 특성을 조사하였다. 연구 대상자 총 394명 중 비닐하우스 농사자는 203명(51.5%), 그리고 일반 농사자는 191명(48.5%)였으며, 남자는 51.3%, 여자는 48.7%였다. 하루 평균 농사를 짓는 시간은 일반 농사자에 비해 비닐하우스 농사자가 길었다. 농약 살포 시 마스크와 방제복 착용류은 비닐하우스 농사자의 경우 일반 농사자에 비해 매우 낮았다. 농부증 양성률은 33.0%로 비닐하우스 농사자와 일반 농사자 간에 유의한 차이를 보이지는 않았다. 그리고, 8가지 농부증 신체증상 중 요통을 호소하는 경우가 가장 많았다. 농부증과 관련된 요인을 분석한 결과, 비닐하우스 농사자의 경우 남자에 비해 여자에서, 농사지은 총 기간이 40년 이상으로 긴 경우, 하루평균 농사짓는 시간이 10시간 이상으로 긴 경우에 농부증 양성률이 유의하게 높았으며, 일반 농사자의 경우에는 남자에 비해 여자가, 그리고 농약 살포 횟수가 적을수록 농부증 양성률이 유의하게 높았다. 다중 로지스틱 회귀 분석 결과 비닐하우스 농사자의 경우, 남자에 비해 여자가 3배 이상, 하루평균 농사짓는 시간의 경우 10시간 미만인 경우에 비해 10시간 이상인 경우가 2.6배, 그리고 일반 농사자의 경우에는 남자에 비해 여자에서 농부증 양성률이 4배 이상 높은 것으로 나타났다. 비닐하우스 농사자의 경우 일반 농사자에 비해 농사시간이 많을 뿐 아니라 운동률이 매우 낮고 수면시간이 상대적으로 적으며 농약 사용시 보호장구의 착용률이 낮으며, 비닐하우스 농사자와 일반 농사자 모두 남성에 비해 여성에서 농부증의 위험이 높아 이에 대한 대책 마련이 시급히 이루어져야 할 것이다. Objectives: This study was performed to estimate the risk factors affecting the farmers' syndrome of vinylhouse and non-vinylhouse farmers in the Gyeongbuk Province rural area. Methods: As a cross-sectional study, a questionnaire survey was conducted from 2003 to 2005. Data was collected from 243 vinylhouse farmers and 236 non-vinylhouse farmers. The data from 394 subjects were used for the final analysis. We surveyed their lifestyle, 8 components of farmers' syndrome and characteristics of farm work. Results: For the vinylhouse and non-vinylhouse workers, 32.0% and 34.0% were positive for farmers syndrome, while 48.3% and 43.5% were suspicious, respectively. The differences between the two groups were not significant. For both groups, the most frequent symptom of farmers' syndrome was lumbago, followed by paresthesia of hand or foot, and shoulder stiffness. Among the vinylhouse workers, the rates of wearing protective equipment and washing the skin after spraying pesticide were significantly lower than among the non-vinylhouse workers. From multiple logistic regression analysis, the risk factors significantly associated with farmers' syndrome were sex {odds ratio (OR)=3.12, 95% confidence interval (CI)=1.42-6.89} and hours of farming per day (OR=2.63, 98%CI=1.22-5.65) among vinylhouse workers. However, sex (OR=4.24, 95%CI=1.87-9.65) was the only the risk factor significantly associated with farmers' syndrome among the non-vinylhouse workers. Conclusions: In conclusion, educational programs and attention to the female farmers were needed in particular. In addition, it was recommended that the farmers wear protective equipment continuously from opening the coverlets of the pesticide container to the completion of pesticide spraying, and wash the skin immediately after contact with pesticides.

First-principles study on the Poisson's ratio of transition-metal dichalcogenides

유용민,양진훈,이주형 한국물리학회 2018 Current Applied Physics Vol.18 No.7

In this study, we investigate the Poisson's ratio of transition-metal dichalcogenides (TMDCs) with a chemical formula of MX2, where M=Mo, W and X=S, Se, respectively, from first-principles. Through density functional theory calculations, it is demonstrated that the Poisson's ratio of MX2 exhibits not only a substantial difference between the planar and vertical values but also a systematic dependence on the chalcogen species. Among the TMDCs, MoS2 displays the strongest anisotropy, which entails a distinctive contracting response under a planar strain. We find that such pronounced anisotropy in the Poisson's ratio of the TMDCs originates from the different filling of the in- (px, py, dxy, and dx2−y2) and out-of-plane (pz, dyz, dzx, and dz2) electronic orbitals depending on the transition-metal elements. These findings shed a new light on the elastic properties of TMDCs which continue to be interesting and show intriguing phenomena.

Objectives : We conducted this study to examine the association between serum GGT levels within the normal range and the risk factors of cardiovascular diseases Methods : We examined the cross-sectional association between serum GGT and the systolic and diastolic blood pressure, fasting blood glucose, total cholesterol, triglyceride, high density lipoprotein cholesterol (HDLcholesterol), and uric acid among 975 subjects that participated in the health examination of a university hospital located in Daegu city. All the patients' GGT levels were within the normal range. Results : After adjustment were made for age, body mass index (BMI), smoking status, drinking frequency, exercise frequency and coffee intake, the serum GGT level was positively associated with fasting blood glucose (p<0.01), total cholesterol (p<0.01), and triglyceride (p<0.01) in men, and it was positively associated with fasting blood glucose (p<0.01), total cholesterol (p<0.05), triglyceride (p<0.01), and uric acid (p<0.01) in women. The associations were not significantly different depending on the status of alcohol drinking or obesity, except for the associations of serum GGT with diastolic blood pressure (P for interaction=0.04) and uric acid (P for interaction=0.04) between the lean and obese subjects. Conclusions : Serum GGT levels within the normal range were positively associated with fasting blood glucose, triglyceride and uric acid in most subgroups irrespective of the drinking or obesity status. These results suggest that GGT has important clinical implications as being more than just a marker of alcohol consumption and hepatobiliary disease.

정보우,손효경,양진훈,이화평,이채용 대한신경과학회 2012 대한신경과학회지 Vol.30 No.4

Background: Both carotid intima-media thickness (IMT) and global risk score of cardiovascular disease were independent risk factors of stroke and heart disease. We assessed the correlation between the 10-year risk of Korean Stroke Risk Prediction model (KSRP) and carotid intima-media thickness. Additionally, from a perspective of carotid IMT measurement following KSRP risk stratification, we analyzed the difference of carotid IMT and plaque according to the KSRP risk strata. Methods: Subjects were 282 persons who visited one hospital for the screening of stroke. The 10-year risk was calculated automatically based on the equation of KSRP model. The maximal carotid IMT and the plaque were adopted as the study variables. The sensitivity and the positive predictive value of the KSRP risk categories were calculated. Results: The correlation coefficient between the KSRP risk and the maximal carotid IMT was 0.29 (p<0.01). The mean (±standard deviation) of KSRP risk of the group with carotid plaque was statistically significantly higher, 5.3 (±4.1), than that of the group without plaque, 3.3 (±3.1) (p≤0.01). The sensitivity of the risk stratum with more than 6% of KSRP risk for the plaque was 28.2%. The positive predictive value of the above cut-point was 48.8%. Conclusions: The 6% of KSRP risk may be considered as the beginning point of intermediate risk stratum to recommend the carotid ultrasonography. However, generalization needs further studies for various populations.

  Purpose: This study is conducted to identify the annual average cancer incidence and the trend of cancer incidence in Daegu during the 5-year period from 1997 to 2001.   Method: Data on newly diagnosed cancer patients from 1997 to 2001 were collected with a standard registration form. Medical record reviewers visited hospitals if necessary, to detect missing cancer patients.   Results: The annual average overall number of cancer patient was 4,606 (male 2,529 and female 2,077). The crude average annual incidence of cancer in male were 211.8 (ASR 251.4) and 169.8 (ASR 151.3) in female. Five major cancers in male were stomach (ASR 60.3), bronchus and lung (ASR 44.8), liver and intrahepatic bile ducts (ASR 40.7), rectum (ASR 11.2), and colon (ASR 10.8). However, in women, those were stomach (ASR 25.3), breast (ASR 19.8), cervix (ASR 14.9), bronchus and lung (ASR 12.7), liver and intrahepatic bile ducts (ASR 11.1). Increases in incidence were found for colon cancer for both sexes, rectal cancer for males, and lung and breast cancer for females. Decreaseswere shown for liver cancer for both sexes and stomach and cervical cancer for females.   Conclusions: Primary prevention of cancer based on results of this study remains important.

Background: The aim of the present study was to determine the population-based prevalence of diabetes mellitus (DM) and prediabetes in a rural district of Daegu City, Korea. Methods: Between August and November 2003, a community-based health survey of adults aged 20 years and older was performed in the rural district of Dalseong-gun in Daegu City. A total of 1,806 of all eligible individuals agreed to participate. Fasting plasma glucose was measured in all participants. Two hour oral glucose tolerance was measured in the 1,773 participants for whom there was neither an established diagnosis of DM nor evidence of DM according to fasting glucose levels. The prevalence of DM and prediabetes was determined according to the 2003 criteria of the American Diabetes Association. Subjects with prediabetes were classified into one of three categories of glucose intolerance: isolated impaired fasting glucose (IFG); isolated impaired glucose tolerance (IGT); or combined IFG and IGT. Results: The prevalence of DM was 12.2%. The highest prevalence rates were observed in subjects in their seventies. A total of 34.7% of all subjects who were assigned a diagnosis of DM in the present study had not been diagnosed previously. The prevalence of prediabetes was 22.7%. The highest prevalence rates were observed in subjects in their fifties. Conclusion: The present study identified prevalence rates of 12.2% for DM (age-standardized prevalence rate [ASR], 6.8%), and 22.7% for prediabetes (ASR 18.5%). These results emphasize the need for community health promotion strategies to prevent or delay the onset of DM in individuals with prediabetes.
