Background: The Korea National Health and Nutrition Examination Survey (KNHANES) is a well-designed survey to collect national data, which many researchers have used for their studies. In KNHANES, although portable spirometry was used, its reliability has not been verified. Methods: We prospectively enrolled 58 participants from four Korean institutions. The participants were classified into normal pattern, obstructive pattern, and restrictive pattern groups according to their previous spirometry results. Lung function was estimated by conventional spirometry and portable spirometry, and the results were compared. Results: The intraclass correlation coefficients of forced vital capacity (FVC) (coefficient, 9.993; 95% confidence interval [CI], 0.988-0.996), forced expiratory volume in 1 second (FEV₁) (coefficient, 0.997; 95% CI, 0.995-0.998), FEV₁/FVC ratio (coefficient, 0.995; 95% CI, 0.992-0.997), and forced expiratory flow at 25-75% (FEF25-75%; coefficient, 0.991; 95% CI, 0.984-0.994) were excellent (all p<0.001). In the subgroup analysis, the results of the three parameters were similar in all groups. In the overall and subgroup analyses, Pearson's correlation of all the parameters was also excellent in the total (coefficient, 0.986-0.994; p<0.001) and subgroup analyses (coefficient, 0.915-0.995; p<0.001). In the paired t-test, FVC, FEV₁/FVC, and FEF25-75% estimated by the two instruments were statistically different. However, FEV₁ was not significantly different. Conclusion: Lung function estimated by portable spirometry was well-correlated with that estimated by conventional spirometry. Although the values had minimal differences between them, we suggest that the spirometry results from the KNHANES are reliable.

Background: The objective of this study was to investigate whether alcohol consumption might affect the quality of life (QOL), depressive mood, and metabolic syndrome in patients with obstructive lung disease (OLD). Methods: Data were obtained from the Korean National Health and Nutrition Examination Survey from 2014 and 2016. OLD was defined as spirometry of forced expiratory volume in 1 second/forced vital capacity <0.7 in those aged more than 40 years. QOL was evaluated using the European Quality of Life Questionnaire-5D (EQ-5D) index. Patient Health Questionnaire-9 (PHQ-9) was used to assess the severity of depressive mood. Alcohol consumption was based on a history of alcohol ingestion during the previous month. Results: A total of 984 participants with OLD (695 males, 289 females, age 65.8±9.7 years) were enrolled. The EQ-5D index was significantly higher in alcohol drinkers (n=525) than in non-alcohol drinkers (n=459) (0.94±0.11 vs. 0.91±0.13, p=0.002). PHQ9 scores were considerably lower in alcohol drinkers than in non-alcohol drinkers (2.15±3.57 vs. 2.78±4.13, p=0.013). However, multiple logistic regression analysis showed that alcohol consumption was not associated with EQ-5D index or PHQ-9 score. Body mass index ≥25 kg/m², triglyceride ≥150 mg/dL, high-density lipoprotein <40 mg/dL in men and <50 mg/dL in women, and blood pressure ≥130/85 mm Hg were significantly more common in alcohol drinkers than in non-alcohol drinkers (all p<0.05). Conclusion: Alcohol consumption did not change the QOL or depressive mood of OLD patients. However, metabolic syndrome-related factors were more common in alcohol drinkers than in non-alcohol drinkers.

Recently, Subway workers have died from lung cancer. According to the Epidemiological Survey of the Welfare Corporation Institute of Pulmonary Disease of the Welfare Corporation, the family members applied for industrial accidents. The radon concentration in the subway work area was found to exceed 10 times the recommended standard value of 148 becquerels (Bq/㎥) in domestic multipurpose facilities. In addition, as a result of the national indoor radon concentration survey conducted by the Ministry of Environment in 2010 and 2013, housing was found to be over 100 becquerels (Bq/㎥) in 41% of the surveyed subjects. In addition, it was found that in 2012, 16.3% of villages exceeded the radon standard value in the survey on natural radioactive materials containing groundwater.

There has been an alarming rise in the incidence of carcinoma of the lung in the world. The increase of the disease has been greater in men than in women, but even in women the rate has doubled in the last 20 years. During the 20 year period 1957 through 1976, 33 women with proven primary carcinoma of the lung were treated at Department of Thoracic Surgery, Seoul National University Hospital. During the period of survey, 170 consecutive cases of primary bronchogenic carcinoma were encountered in men, a male to female ratio of 5.2: 1. Ages of patients with bronchogenic carcinoma in women ranged from twenty-seven to sixty-eight years and most of them were over 40 years of age. The duration between the onset of symptoms and admission was about 9 months and the most common complaints were cough [66.6%], chest pain [60.6%], hemoptysis [48.4%] and dyspnea [45.4%]. Bronchogenic carcinoma developed most frequently in the upper lobes, and twelve [36.3%] of cases were squamous cell type, nine [27.2%] were anaplastic cell type, six [18.2%] were adenocarcinoma, one was alveolar cell type and five were unclassified type, in contrast to the usual predominence of adenocarcinoma among women in other reports. One half of the patients were inoperable and resection was feasible in only 24.2 per cent of the patients. There was no operative mortality but one case had bronchopleural fistula after pneumonectomy. Most patients with bronchogenic carcinoma in women were from large cities. Cigarette smoking appeared to be related to the occurrence of the squamous cell and anaplastic cell carcinoma because all heavy smokers had squamous cell or anaplastic cell carcinoma.

Purpose: The aim of this study was to identify the influence of knowledge, attitude and preventive health behavior of cancer on nicotine dependency in male college students who have a habit of smoking. Methods: In this study, a cross-sectional survey design was adopted for the 254 male college students who smoke in D and S city. The data was analyzed for descriptive statistics, t-test, Pearson's correlation coefficient and multiple regression analysis using the SPSS 20.0 program. Results: Knowledge about lung cancer (${\beta}=-.407$, p<.001), preventive health behaviors about cancer (${\beta}=-.223$, p<.001) and the smoking period ($5years{\leq}$) (${\beta}=.198$, p=.001) were identified as the factors influencing nicotine dependency of the subjects. The model explained 33% of variance in nicotine dependency (F=20.49, p<.001). Conclusion: The results suggest that anti-smoking educators should include the strategies to increase knowledge about lung cancer and preventive health behaviors of cancer, and to reduce the smoking period in their smoking cessation program.

A basic survey of Echinococcus infection in cattle slaughtered at seogipo abattoir, Jeju Island was carried out. The incidence of hydatid cyst was 0.4% in the native cattle, that is 4 heads out of 993 heads of the slaughtered cattle. The hydatid cysts with or without scolices were found in the liver and lung, and the speciation of them was determined as Echinococcus granulosus granulosus with the morphological and biological characters. The infection rates of bovine echinococcosis were as high as 6.8% to 27.5% from 1936 to 1940 in Jeju cattle, but it has been found greatly decreased to 0.4% in this survey. The main reason of decrease in the incidence was cleared with the fact that wild dogs were abundant at that times.

본 연구는 남성 흡연자들의 금연에 대한 관심도와 금연에 대한 관심도를 규정하는 요인 간의 관련성을 규명하고자 시도하였다. 조사대상은 D광역시청 및 그 산하 지청에 근무하고 있는 남성 공무원 중 조사시점에서 현재 흡연자인 593명으로 하였다. 조사방법은 2015년 10월에 구조화된 무기명 자기기입식 설문지를 이용한 설문조사에 의하였다. 연구결과, 조사대상자의 "금연에 대한 관심도"는 "금연에 대한 행동의 계기", "폐암에 대한 이환 가능성 인지", "폐암에 대한 심각성 인지" 및 "금연에 대한 행동실천의 인지된 이익"과 유의한 양의 상관관계를 보였다. 공분산 구조분석 결과, 금연의 관심도를 규정하는 요인들의 "금연에 대한 관심도"를 높이는 요인으로는 "금연에 대한 행동실천의 인지된 이익 및 장애"가 가장 큰 요인이었으며, 다음으로 "폐암 이환 가능성 인지 및 심각성 인지", "금연에 대한 행동의 계기" 및 "사회적지지 네트워크"의 순이었다. 위와 같은 연구결과는 금연에 의한 암 예방효과와 흡연에 의한 건강장애의 심각성의 인식은 금연에 대한 관심을 높이는 요인이 되고 있음을 시사한다. 따라서 향후 남성 흡연자들의 금연지도에 있어서는 대상자의 금연의 관심도를 높이는 요인들을 정확하게 파악하여 끈기 있게 지도해 나가는 것이 중요하다고 생각된다.
