Objectives: Socioeconomic status plays an important role in health care and disease prevention. This study aimed to examine the association between socioeconomic status, measured by education levels and household income, and gastric cancer screening. Methods: A total of 21,220 community-dwelling adults aged 40 to 69 years within a defined geographic area participated in a community health survey in 2009 and 2010. The survey was conducted using a structured questionnaire by trained investigators who visited the subjects' households directly. Logistic regression analysis was used to determine the relationship between self-reported participation in gastric cancer screening and socioeconomic variables (education and household income). Results: The gastric cancer screening rate was 52.1% for subjects in their forties, 63.7% for those in their fifties, and 67.3% for those in their sixties. In multivariate analysis, higher education and income levels were associated with higher rates of gastric cancer screening (high school vs. elementary school: odds ratio [OR] 1.41, 95 % confidence interval [CI] 1.26-1.58; highest income quartile vs. lowest income quartile: OR 1.62, 95% CI 1.44-1.84). The gradient between income and screening rate was more pronounced in the population aged 40 to 49 years than in the other age groups. Conclusions: This study demonstrates that lower socioeconomic status is associated with decreased participation in gastric cancer screening. Our findings suggest that the screening program should be focused on low-income and less-educated populations, especially among younger adults, to reduce health disparities.

There have been many efforts to identify and eliminate the direct causes of the construction accident, but many accidents are still occurring in the construction industry. The main reason for the construction accident is not because of ignorance of the causes, but because of safety insensitivity. This paper analyzes why construction workers feel safety insensitivity and how safety insensitivity varies depending on their age and work experience. A survey of 103 construction workers confirmed that systematic safety education is the most important factor in minimizing safety insensitivity of construction workers. On the other hand, economic reasons such as cost reduction were identified as the most tempting factor to increase safety insensitivity. In addition, the survey results showed that those in their 40s and 50s, the largest proportion of construction workers, have a significantly higher level of safety insensitivity than those in their 20s and 60s. These findings are expected to be valuable source that can be used to prevent construction safety accidents.

성대마비 이비인후과 영역에서는 비교적 빈번하게 관찰되는 질환으로 대부분은 미주신경과 그 분지인 반회신경이 경정맥공에서 후두까지의 주행중에 생긴 질환에 의하여 이차적으로 발생하거나, 드물게는 윤상갑상연골 관절의 고정에 의사여 발생하게 된다. 임상적인 진단은 간접후두경이나 화이버옵틱후두경 검사법에 의하여 간단하게 내려질 수 있으나, 그 발생원인은 다양하며, 임상적인 양상 및 그에 따른 치료 원칙도 다르게 나타난다. 이에 연자들은 1986년 1월 1일부터 1990년 12월 31일까지 5년간 국립의료원 이비인후과에 내원한 환자중 성대마비로 진단된 환자 61례에 대한 후향적 기록 분석에 의해 성별, 원인별, 측별, 성대의 위치, 및 그에 따른 치료방향에 대하여 비교 검토하여 다음과 같은 결과를 보였다. 1)성별은 남녀비가 3:2로 남자가 많았으며, 연령별 분포는 20대에서 70대까지 비교적 균등하였으나 50대(23.0%)에서 가장 많은 분포를 보였다. 2)원인으로는 원인불명이 16례(26.2%), 갑상선수술 8례(13.1%), 폐결핵과 기관내삽관후 각각 6례(9.8%), 폐암 5례(8.2%) 순이었다. 3)마비된 성대의 측별 분포는 편측성이 51례(83.6%), 양측성이 10례(16.4%)이며, 편측성중 좌측이 37례(60.6%)로 가장 많았다. 마비된 성대의 위치는 부정주위가 33례(54%)로 가장 많았다. 4)즉 증상은 단지 애성만 있었던 례가 31례(50.8%), 호흡곤란 혹은 기도흡인등을 동반한 애성이나, 애성을 동반하지 않은 례도 있었다(3례). 증상 발현후 병원 내원까지 기간은 2개월이내가 가장 많았다. 5)16례에서 수술적 처치가 시행되었거나(9례), 혹은 자연치유가 관찰되었는데(7례) 편측성마비때 갑상연골성형술 2례, 양측 마비때 후두외접근법에 의한 피열연골절제술 4례, 레이저를 이용한 피열연골절제술 2례, 승모판 협착증에 의한 편측성 성대마비에서 개심술후 성대마비 회복 1례, 자연 치유는 7례에서 관찰되었으며 6례에서는 증상발현후 6개월이내에 회복되었다.

The objectives of this study were to analyze the socio-economical factors related to smoking and drinking behaviors using the Korea Welfare Panel data. The key variables were sex, age, frequency of health and medical facilities visit, subjective health level, smoking level, drinking level, depression symptoms, and low income level. Since the health variables in the Welfare Panel data were limited, the analysis was exploratory. In male population of those older than 30 years old, low income group people were more likely to smoke cigarettes than the general income population. In the result of the Chi square analysis, the smoking rate showed significantly different relationships with the different age groups, gender and income level. According to the descriptive analysis, persons with low income level were more likely to experience health risk behaviors and showed more medical service utilization. The utilization of the local public health centers was 4.6% for the Bow income level and 1% for the general level. The higher smoking rate was associated with the younger age, and the lower income. The smoking rate in the age category from 20 to 29 was 23.3% for the general level and 25% for the low income level. On the other hand, the drinking rate was even higher in the general families. The rates of non use of alcohol was 36.7% in the general families and 58.4% for the low income families. For both smoking and high risk drinking issues, demographic and sociological variables such as sex, age, education levels and income levels were analyzed, and there wer significant relationships. Health risk factors were serious for males, with age groups of 20's and 30's, lower education level, and in a low income family. In general, females were more unhealthy. The rates of smoking and drinking were higher in the low income level. Even in the health and nutrition survey results in 2005, persons in the low income class were experiencing poorer health in health level or the degree of action restriction. Since the effects of the health promotion could not be measured in a short period of time, it has not been easy to create the basis for the substantial effects. Factors related to health risks needs to be continuously studied using data from diverse field.

차량에서 전조등의 밝기 변화가 운전자에게 불쾌감과 스트레스를 제공한다면 운전자 및 보행자의 안전에 위협이 될 수 있을 뿐만 아니라 차량의 전체성능에 의구심을 유발시킬 수 있다. 그러므로 차량 전조등의 밝기변화 패턴에 영향을 미치는 전조등의 전압과 시간을 변수로 하여, 순간적으로 밝기변동이 발생하였을 경우, 연령대별(20/60대)로 운전자가 느끼는 심리적인 반응(불쾌감)이 어떠한 경향을 갖는지를 파악하는 것이 중요하다. 따라서 본 논문에서는 운전자가 순응하고 있는 전조등에 의한 노면상황을 모의하고 전조등의 전압이 13.6[V]에서 12[V]까지 변동하는 빔 패턴을 화면으로 구성하여 전조등의 순간적인 밝기변동을 모의하였다.
