최근 한 조사에 따르면 담배를 피우지 않더라도 매일 4시간 이상 간접흡연에 노출 될 경우 당뇨병에 걸릴 위험이 2배 가까이 높아지는 것으로 나타났다. 흡연이 당뇨병 발병에 영향을 끼치는 연구결과만 봐도 건강에 얼마나 좋지 않은지를 짐작할 수 있다.

Hypertension has a steadily increasing incidence rate as well as represents a risk factors for secondary diseases such as cardiovascular disease. Therefore, it is important to predict the incidence rate of the disease. In this study, we constructed nomograms that can predict the incidence rate of hypertension. We use data from the Korean National Health and Nutrition Examination Survey (KNHANES) for 2013-2016. The complex sampling data required the use of a Rao-Scott chi-squared test to identify 10 risk factors for hypertension. Smoking and exercise variables were not statistically significant in the Logistic regression; therefore, eight effects were selected as risk factors for hypertension. Logistic and Bayesian nomograms constructed from the selected risk factors were proposed and compared. The constructed nomograms were then verified using a receiver operating characteristics curve and calibration plot.

The osteoradionecrosis of the mandible can be a serious complication of radiotherapy for malignancies of the head and neck. The cause and pathogenesis of osteoradionecrosis are unclear and anecdotal. There are various treatment-, patient- and tumor-related risk factors on development of osteoradionecrosis. The treatment of osteoradionecrosis relies on conservative measures (antibiotics, debridement, irrigation and HBO) and surgical measures (sequestrectomy, marginal resection and segmental resection with or without reconstruction). But the indications are not defined. We present the two cases of patients who were not controlled by conservative treatment but good-resulted by surgical treatment.

This study was conducted from November 1, 2017 to November 30, 2017 in 268 women in late postmenopausal period in D and S shipyards located in G city. The subjects were divided into two groups according to the risk factors of cerebrovascular disease according to the presence or absence of risk factors of cerebrovascular disease. The subjects were divided into two groups according to their general characteristics, cerebrovascular disease prevention knowledge, attitude and health behavior. The variables that had statistically significant difference in health group and risk group were age (F=92.239, p<.001), cohabitation type ($x^2=20.056$, p<.001), income level ($x^2=39.023$, p<.001), the number of working hours per week (F=32.217, p<.001), the number of working years (F=12.310, p=.001), family history of cardiovascular disease ($x^2=233.442$, p<.001), subjective health status($x^2=19.058$, p=.001). There was a significant difference between the two groups in the degree of knowledge related to prevention of cardiovascular disease (F=2.679, p=.008) and health behavior fulfillment (F=4.339, p<.001). (r=.348, p<.001), the risk group had a higher knowledge (r=.279, p=.002), and the other group Attitude (r=.194, p=.030) showed a statistically significant correlation. Based on this, it is necessary to develop and apply an intervention program considering the characteristics of vulnerable group of cerebrovascular disease.

Purpose: To identify the epidemiological characteristics and risk factors of coronavirus disease 19 (COVID-19) outbreaks depending on the type of educational facility by analyzing the COVID-19 cluster associated with educational facilities. Methods: This study is based on epidemiological investigation of COVID-19 cluster in Gangwon-do, Korea from December 10, 2020 to September 23, 2021 reported to the Korea Disease Control and Prevention Agency's Integrated Disease and Health Management System. Four hundred seven patients in 19 facilities, classified as cluster related to educational facilities, were the study population. The result of preliminary epidemiology survey report, in-depth epidemiological survey by phone and the result of risk assessment derived from the field epidemiology investigation were retrospectively analyzed to evaluate infectivity and the characteristics of the risk factors. Results: There were total of 407 confirmed patients related to 19 educational facilities, with 204 students under the age of 19 (50.1%). One hundred fifty-five preceding spreaders were from families (38.1%) and 125 were the teachers (30.7%). The place exposed to confirmed patients was the highest with 139 people (34.2%) at home. Conclusions: It was confirmed that the cause of the occurrence of clusters related to educational facilities was higher due to family transmission than the risk of facilities in schools. Nevertheless, continuous efforts should be made to control infection in educational facilities, and that teachers' implementation of principles for prevention of COVID-19 personal hygiene in their daily lives should be strengthened.

누적외상성질환(Cumulative Trauma Disorders)의 발병 위험요인을 찾아내기 위한 기법의 하나로 체크 리스트가 활용된다. 이미 외국에서는 누적외상성질환의 예방을 위한 체크리스트 관련 연구가 상당히 진 척되었다. 체크리스트를 이용하여 누적외상질환의 위험요인을 발견하고 이에 대한 예방 대책을 세우기 위한 일환으로서, 본 연구에서는 우리 나라 제조업 현장의 누적외상성질환 예방을 위한 체크리스트의 개발 및 이의 과정, 목적과 활용에 대하여 연구하였으며, 앞으로 제조업 현장에서 활용이 가능한 체크리스트를 개발하였다.

This paper demonstrates the effectiveness of advanced spatial modeling techniques for environmental monitoring and impact assessment through a case study of Chernobyl nuclear accident occurred in 1986. Land-cover types changed after the accident are analysed by a post classification comparison method using bi-temporal Landsat TM data acquired in 1986 and 1992 near the accident site. Spatial modeling including various kriging algorithms are also applied to analyze the relationships between Cesium concentrations in soil and thyroid cancer incidence rates in Belarus, which was greatly damaged by the accident. The change detection results clearly showed the decrease of croplands and the increase of abandoned lands, and concrete structures were newly built around the nuclear plant to prevent the spread of radioactive contamination. In Belarus, high Cesium concentrations were observed in southern areas with high thyroid cancer risk estimated by Poisson kriging. Geographically weighted regression, which could account for geographic variations of independent variables including Cesium concentrations and distances from the Chernobyl nuclear power plant, was applied to extract the relationships between the independent variables and the thyroid cancer risk. The estimated risk values showed a correlation coefficient value of 0.98 with respect to the thyroid cancer risk values, which implied that the thyroid cancer risk in Belarus was affected by the accident. In conclusion, it is expected that advanced spatial modeling techniques applied in this study would be useful for environmental impact assessment and public health research.

당뇨병은 전 세계적으로 급격하게 증가하면서 심각한 대혈관 및 미세 혈관 합병증들의 원인이 되고 있으며 대다수 선진국에서 당뇨병은 만성 신질환 및 말기 신부전의 가장 중요한 원인으로 알려져 있다. 당뇨병성 신증은 단백뇨를 특징으로 하며 30% 정도의 환자에서는 혈뇨도 관찰된다. 그래서 당뇨병성 신증의 발병 검진은 미세알부민뇨 검사로 하는 것이 가장 이상적이며 제 1형 당뇨병환자는 일반적으로 당뇨병 발병 5년 이후에 하며 위험인자가 있는 환자는 더 조기에 한다. 제 2형 당뇨병환자는 당뇨병 진단 시점부터 매년 하는 것을 원칙으로 한다.
