본 연구는 행정동 내 범죄위험의 분포양상을 유형화하고, 유형별로 범죄기회를 유발하는 영향요인을 분석하였다. 행정동별 범죄위험 등급의 평균, 표준편차, 지니계수를 활용하여 유형화 기준을 설정하고, 이를 바탕으로 8가지 유형을 도출하였다. 이후 로지스틱 회귀분석을 통해 행정동별 범죄위험 분포양상의 유형을 결정짓는 요인을 확인하였다. 또한 대표적 유형인 ‘균등 저위험 (LLL)’과 ‘불균등 고위험(HHH)’ 지역을 대상으로 공간회귀분석을 수행하여, 각각의 범죄위험 평균에 영향을 미치는 요인을 비교하 였다. 분석 결과, 유흥시설, 주거용 건물 등 촉진요인과 지구대・파출소, 비상벨 등 억제요인의 작용 방식은 유형별로 상이하게 나타났으며, 동일한 영향요인이라 하더라도 유형에 따라 효과의 방향과 강도가 달라짐을 확인할 수 있었다. 본 연구의 결과는 범죄위험 분포양상의 유형별로 영향요인에 대한 차별적 해석이 요구되고, 목적에 따라 분석 범위 및 대상을 적절히 설정할 필요가 있음을 시사한다. 이러한 점에서 본 연구는 범죄기회 억제를 위한 지역 맞춤형 정책 수립의 기초 연구로 활용될 수 있을 것이다.
This study was conducted to verify the impact of hazardous risk factors in manufacturing workplaces on worker safety behaviors, focusing on the mediating effect of safety climate, and to establish safety management strategies in manufacturing workplaces and to suggest practical measures to improve worker safety. For this study, the results of the ‘10th Occupational Safety and Health Survey’ conducted by the Korea Occupational Safety and Health Agency’s Occupational Safety and Health Research Institute in 2021 were used as analysis data for 3,255 manufacturing workplaces with 20 or more regular workers. The data were analyzed using the SPSS 24.0 program for descriptive statistical analysis, validity and reliability verification, correlation and multiple regression analysis, and hierarchical regression analysis. As a result of the study, first, hazardous risk factors were confirmed to have a negative effect on workers' safety behaviors. Second, hazardous risk factors were confirmed to have a negative effect on safety climate. Third, safety climate was confirmed to have a positive effect on workers' safety behaviors. Fourth, it was verified that the safety climate had a partial mediating effect in the relationship between hazardous risk factors and workers’ safety behavior in the workplace. Through this study, it was found that hazardous risk factors had a negative effect on workers’ safety behavior. This emphasizes that efforts to systematically manage and minimize hazardous risk factors in the workplace are important in promoting workers’ safety behavior. In addition, it was confirmed that the safety climate had an important mediating effect in the relationship between hazardous risk factors and workers’ safety behavior. In other words, it can be seen that the safety climate can alleviate the negative effect of hazardous risk factors on workers’ safety behavior. These research results suggest that reducing hazardous risk factors in the workplace and improving the safety climate can have a positive effect on workers’ safety behavior practice, thereby preventing industrial accidents.

This study was performed to analyze dietary influences on the regulation of low-density lipoprotein cholesterol (LDL-C) in postmenopausal women using the 2019-2021 Korea National Health and Nutrition Examination Survey (KNHANES). A total of 1,724 women were classified into cardiovascular risk groups based on risk factors and differentiated into high LDLC and normal groups according to the target serum LDL-C levels. The risk group distribution was as follows: Very high-risk group (6%), high-risk group (49.4%), moderate-risk group (42.3%), and low-risk group (2.3%). The high LDL-C group demonstrated abdominal obesity and prediabetes, with their carbohydrate energy intake exceeding the Korean dietary guideline recommendations of 65%. Increased fat (OR 2.67, 95% CI; 1.19-6.02) and cholesterol (OR 2.43, 95% CI; 1.02- 5.77) intake correlated with higher LDL-C risk. The high LDL-C group showed elevated saturated fat and reduced polyunsaturated fat consumption (p for trend <0.001). Thus, to regulate the LDL cholesterol levels in postmenopausal women, they maintain an appropriate weight in addition to managing abdominal obesity and continuously monitoring blood sugar levels. Furthermore, it is important to limit the intake of high saturated fat meats and consume sufficient protein from sources such as beans, fish, and eggs, which contain healthy unsaturated fats.
최근 자율주행 차량의 등장으로 인해 기존의 교통 시스템에 많은 변화가 생길 것으로 보이며, 운전자가 주행하던 차량과는 다른 행태로 인해 기존 비자율주행 차량들이 초래하는 고위험 상황의 요인과는 다른 새로운 요인들이 도출될 것으로 보인다. 하지만, 현 시점 국내 에서는 자율주행 차량이 실제로 주행하고 있지 않기 때문에 주행행태를 포함한 데이터 기반의 주요 요인 분석 및 도출에 한계가 있다. 따라서 현 시점에서 자율주행 차량이 혼재하는 환경에서 고위험한 상황을 정의할 수 있는 요인을 도출하기 위해서는 사례 중심의 분석이 필요하다. 따라서 본 연구에서는 기존 국내·외 자율주행차량과 관련된 다양한 논문 사례를 DB화하여 이를 정량적으로 평가할 수 있는 메타 분석(Meta-Analysis) 기법을 통해 향후 자율주행차량이 혼재하는 교통 네트워크에서 안전성을 증진하기 위한 고위험 유발의 주요 요인을 도출하고자 하였다. 본 연구에서 DB화한 논문은 자율주행 차량과 관련된 총 4가지(사고요인, 시나리오, 예측모델, 법규)에 해당 하는 분야로 분류하여 수집하였으며, 2015년부터 2024년 까지 최근 10개년에 해당 되는 사례를 수집하여 분석을 수행하고 주요 요인을 도출하였다. 본 연구의 결과는 향후 자율주행 차량 혼재 시 고위험 상황의 주요 요인들을 바탕으로 각 요인에 기반한 자율주행차량 혼재 시 고위험 상황에 대한 정의를 할 수 있으며, 이러한 고위험 요인들에 의해 도로교통의 안전성이 저해될 수 있는 요인에 대한 사전 예방을 수행할 수 있을 것으로 기대된다.

This study aimed to quantitatively analyze the risk using data from 329 safety accidents that occurred in aquaculture fisheries management vessels over the recent five years (2018-2022). For quantitative risk analysis, the Bayesian network proposed by the International Maritime Organization (IMO) was used to analyze the risk level according to the fishing process and cause of safety accidents. Among the work processes, the fishing process was analyzed to have the highest risk, being 12.5 times that of the navigation, 2.7 times that of the maintenance, and 8.8 times that of the loading and unloading. Among the causes of accidents, the hull and working environment showed the highest risk, being 1.7 times that of fishing gear and equipment, 4.7 times that of machinery and equipment, and 9.4 times that of external environment. By quantitatively analyzing the safety accident risks for 64 combinations of these four work processes and four accident causes, this study provided fundamental data to reduce safety accidents occurring in aquaculture fisheries management vessels.
We analyzed risk factors of coastal gillnet fishers during fishing process and considered work safety measures to reduce safety accidents during fishing using a UWB (ultra wideband) based positioning system. The static position accuracy of the UWB based positioning system was 45 cm. When entering a port, there is a risk of falling overboard. When casting a net, there was a risk of falling overboard due to being hit by fishing gear or guards, or getting caught in a buoy line or sinker line. When hauling a net, there is a risk of getting caught between fishing gear and net hauler, and the risk of musculoskeletal disorders due to repetitive work over a long period of time. Most safety accidents during work on fishing boats are blamed on human errors of the fisher and skipper, but safety accidents occur due to a mixture of mechanical and equipment factors, work and environmental factors, and management factors in addition to human errors. Therefore, the 4E were presented as countermeasures against the 4M, which are causes of safety accidents, and the proposed measures were used to identify risk factors for operation process, comply with work safety rules, and ensure the wearing of personal protective equipments. We need to reduce safety accidents during work by making it part of our daily routine. These research results can be used in the future for optimal placement of fishing gear and fishing nets in other coastal industries where safety accidents occur frequently.
Abstract Purpose : To investigate the prevalence and risk factors for dry eye syndrome (DES) in university students. Methods : A cross-sectional survey of university students was conducted through a combination of online smartphone surveys using Google Forms and face-to-face questionnaires. The questionnaire consisted of questions about risk factors for dry eye disease and the 5-item Dry Eye Questionnaire (DEQ-5). Results : A total of 288 university students participated in the study. The average age was 22.5±2.1 years, w ith 54.2% female a nd 4 5.8% m ale. The m ean of t he D EQ-5 s core w as 7.37±4.65, and the prevalence of DES by DEQ-5 was 47.2%. Female gender (p=0.012), digital screen use for more than 8 hours per day (p=0.018), digital screen use for more than two hours without a break (p=0.035), contact lens wear (p=0.016), refractive surgery (p=0.020), less than 6 hours of sleep per night (p=0.0169, and allergic conjunctivitis (p=0.016) were relevant associated risk factors for DES. Conclusion : The prevalence of DES in young adults may be underestimated in comparison to middle-aged and older adults. The severity of DES depends on several factors, including genetic and environmental factors, so identifying risk factors would help with proper prevention and early diagnosis. Key words : DEQ-5, Dry eye syndrome, Risk factor
In this study, the AHP (analytic hierarchy process) technique was used to analyze the risk of expected risk factors and fishing possibilities during gillnet fishing within the floating offshore wind farms (floating OWF). For this purpose, the risks that may occur during gillnet fishing within the floating offshore wind farms were defined as collisions, entanglements, and snags. In addition, the risk factors that cause these risks were classified into three upper risk factors and ten sub risk factors, and the three alternatives to gillnet fishing available within the floating OWF were classified and a hierarchy was established. Lastly, a survey was conducted targeting fisheries and marine experts and the response results were analyzed. As a result of the analysis, among the top risk factors, the risk was the greatest when laying fishing gear. The risk of the sub factors for each upper risk was found to be the highest at the berthing (mooring), the final hauling of fishing net, and the laying of the bottom layer net. Based on the alternatives, the average of the integrated risk rankings showed that allowing full navigation/fisheries had the highest risk. As a result of the final ranking analysis of the integrated risk, the overall ranking of allowing navigation/fisheries in areas where bottom layer nets were laid was ranked the first when moving vessels within the floating OWF was analyzed as the lowest integrated risk ranking of the 30th at the ban on navigation/fisheries. Through this, navigation was analyzed to be possible while it was analyzed that the possibility of gillnet fishing within the floating OWF was not high.
Honeybee winter failure and mortality are a big issue in korea, especially from 2021 to 2023. Traditionally, honeybee winter failure has been estimated as Approximately 10-20%. However, for last 2 years, we had more than 35% of winter failure which impacted not only beekeeping sectors but also agriculture and the whole society as well. Primary factor was ascribed as honeybee mite resistance development to conventional acaricudes. Coinhabitance of tropilaelaps mite in honeybee complicated the mite problem. Further threat of vespa hornets especially in fall season would exerbate the wintering condition. More important is that the more frequent abnormal weather condition in fall and winter season could affected the winter bee production and maintenance of honeybee overwintering physiology. On these situation, we also observed some diseases were associated to the death of bees.

본 연구는 한국인 인구집단에서 폭식행동, 음식중독을 식별하고, 해당 증상들이 비만 및 섭식행 동, 정신건강, 인지적 특성과 어떠한 연관성을 보이는지 규명하고자 하였다. 이를 위하여 정상체중 및 비만 체중에 해당하는 한국인 성인 257명을 대상으로 섭식문제(예: 폭식, 음식중독, 음식갈망), 정신건강(예: 우 울), 인지기능(예: 충동성, 정서조절)에 관한 임상심리검사 척도를 측정하였다. 비만 여부와 성별에 따라 그 룹을 나누었을 때, 비만체중 여성에서 폭식행동이 46.6%, 음식중독이 29.3%로 가장 빈도가 높았다. 성향 점수 매칭 후 데이터로 독립성 검정을 수행한 결과, 폭식행동 및 음식중독이 비만체중 집단에서 정상체중 집단보다 더 많이 나타나는 것을 확인하였다. 또한 폭식행동과 음식중독 유무에 각 심리검사 척도 요인이 미치는 영향력을 파악하고자, 전진선택법을 적용한 로지스틱 회귀모델을 구축하였다. 로지스틱 회귀분석 결과, 폭식행동에는 섭식장애, 음식갈망, 상태불안, 정서조절(인지적 재해석) 및 음식중독이 주로 관여하였 고, 음식중독에는 음식갈망, 폭식행동과 함께 비만과 연령의 교호작용, 교육년수가 유의하게 작용하는 것으 로 나타났다. 본 연구는 한국인 성인을 대상으로 한 체계적 연구로서, 폭식행동과 음식중독이 여성 및 비만 인에서 특히 더 많이 나타남을 확인하였다. 폭식행동과 음식중독에는 일부 섭식문제(예: 음식갈망)가 공통되게 관여하나, 정신건강 및 인지적 위험요인에는 차이가 있었다. 따라서 음식중독과 폭식행동은 서로 구 별되는 개념으로 두고, 각각의 기질적·환경적 위험요인을 깊이 있게 탐구하는 것이 필요하다.
본 연구는 한국청소년정책연구원에서 실시한 한국아동·청소년 패널조사의 초등학교 4학년 패널 의 7차년도 자료인 고등학교 1학년에 재학중인 청소년을 대상으로 의사결정나무분석을 통하여 청소년 지 위비행의 고위험군의 특성을 파악하고, 그 영향요인을 확인하였다. 본 연구의 대상자 1,979명 중 지위비행 집단은 264명으로 전체의 13.3%로 나타났다. 청소년 지위비행의 고위험군은 남자이면서 긍정적 양육방식 을 낮게 인식하는 군이었다. 긍정적 양육방식이 가장 중요한 영향요인으로 나타났으며, 그 다음으로 성별, 정서문제, 교사관계, 성취가치 순이었다. 청소년 지위비행을 예방하기 위해 양육방식에 대한 부모교육 프로 그램, 남자 청소년에게 특화된 중재 프로그램의 개발이 필요하다. 또한 공격성에 초점을 두었던 그 동안의 중재에서 더 나아가, 우울, 사회적 위축 등의 정서문제를 포괄적으로 다루는 중재가 요구된다. 특히 청소년 에게 중요한 학교환경에서 교사관계가 가장 중요한 영향요인으로 밝혀진 바, 청소년 지위비행의 원인과 결 과에 대한 교육, 상담기법에 대한 훈련을 통한 교사와의 관계 증진이 청소년 지위비행을 예방하는 보호요 인으로 작용할 것이다.
For the geological risk assessment of deep-depth underground condition by excavation work or tunneling, since rocks and geologic structure of each country is different, it is necessary to objectify or classify quantitatively deep-depth underground risk evaluation in accordance with Korean geologic characteristics. It could be summarized major factors of rock failure and underground space deformation by geological and geotechnical features as geologic structures, overburden, rock mass characteristics, groundwater, high stress and additional categories. Induced main factors that could be identified and predicted intermediate to deep-depth underground risk through literature investigation and analysis study on research trend related to the underground geological engineering. In order to assessment the risk of rock mass excavated from 100 m or more to several kilometers deep below the ground are classified into about 19 factors, and can be divided into 6 categories. Using these risk factors as basic data, weights for each factor for each category can be set, and further, the risk of excavated rock mass can be calculated.
In addition to simply providing quality food to the people, the fishery industry must be maintained and developed because it has various functions such as national food security, preservation of natural scenery, protection of national territory, and revitalization of the local economy. However, risk factors such as climate changes and environmental destruction have raised concerns about the sustainable development of the industry. Since these risk factors are becoming larger and more complex over time, it is time to conduct research related to the risk of the fishery industry. Therefore, the purpose of this study is to explore the risk factors facing the fisheries at this point, to analyze the economic ripple effect of regional fishery product supply shortage, and to draw implications. As a result of this study, the economic ripple effect of fishery product shortage per won was highest in Busan, followed by Gangwon, Gyeongnam, and Gyeongbuk. Considering the size of the local fishery industry, Busan had the highest supply shortage per 1% of local fisheries production. It is also necessary to prepare special risk management and countermeasures for these regions since the effect of supply shortage in regions such as Jeonnam, Gyeongnam, and Jeju is large compared to other regions.
