  • Currently available evaluation checklists are developed for specific purposed using different parameters and items determined by different weighting factors. Those items with different weighting are sometimes said that they are based on the engineering judgement and leap of faith and, therefore, there is a limitation to adapt those checklists for slope-stability evaluation in the field. This study reviews factors affecting slope stability, analyze the relationship between those factors and slope failures using artificial neural network, and proposed a slope-stability evaluation model for adequate weighting for the factors.

  • The purpose of this study is to investigate the current status of firefighting seatbelt use and factors affecting the wearing seatbelt of firefighters. The seatbelt use of citizens was also studied for comparative study. Two T-tests were conducted to confirm the characteristics of firefighters' safety belts wearing firefighters. As a result, there was a statistically significant difference, on seatbelt use in general vehicles, between firefighters and citizens. And a significant difference between fire vehicles and general vehicles, on firefighters' seatbelt use, and the average was lower in fire vehicles. Factor analysis, reliability analysis, correlation analysis and multiple regression analysis were conducted to 10 influential factors affecting seatbelt use of firefighters'. And factor analysis and reliability analysis revealed two major factors (Physical factors, Learning factors). In multiple regression analysis, it was confirmed the two independent factors had a positive effect on the dependent variable, the rate of seatbelt use of firefighters'.

  • Objectives: This study was conducted to determine firefighters' work-related accident rate and investigate the factors affecting their on-site safety. Methods: We developed a web-based self-reported questionnaire designed to inquire into firefighters' work-related accident experience and the factors (4M; Man, Machine, Media, Management) affecting firefighters' on-site safety. We distributed questionnaires to all members of firefighting organizations in South Korea by e-mail and 9,149 were returned, resulting in a response rate of 23.1%. Results: Fifteen point seven percent of the respondents reported work-related injuries within the past one year, and 35.1% answered that current accident investigation reports are not helpful for preventing the same accident from recurring. Among the 4M factors, the one most affecting firefighters' on-site safety in the order of priority is the Man factor, followed by Machine, Media, and Management. However, the results from detailed sub-categorical factors showed some differences. 'Lack of human resources', one of the Management factors, was the most influential (70.3%), followed by 'worn-out equipment' under the Machine factor (67.2%). The viewpoint of elements of the Man factor including 'forgetting instructions' and 'fatigue and illness' were significantly different according to firefighters' rank. The higher the firefighter's rank, the more they answered 'forgetting instructions,' while the opposite was the case for 'fatigue and disease'. Conclusions: The present firefighters' accident investigation report needs to be improved, and the 4M method could prove very useful. In addition, it is necessary to set up a proper firefighters' accident investigation and prevention system.

  • 본 연구는 65세 미만 성인과 65세 이상 노인에서 고혈압 위험요인을 파악하기 위한 서술적 조사연구이다. 6차 고령화 연구패널조사를 활용하여 6,152명의 연구대상자를 분석하였으며, 수집된 자료는 SPSS 23을 이용하여 카이검정과 로지스틱 회귀분석을 시행하였다. 고혈압 유병률에 영향을 미치는 위험요인에 대한 로지스틱 회귀분석 결과는 65세 미만 성인과 65세 이상 노인 둘 다에서, 주관적 건강상태, 당뇨병 유무, 심장질환 유무, BMI에 따른 비만정도가 위험요인으로 나타났고, 65세 미만에서는 만성폐질환, 소화기계 질환, 음주가, 65세 이상에서는 거주지역, 관절염 및 류마티스 질환, 흡연, 인지기능 정도가 고혈압에 영향을 미치는 위험요인으로 나타났다. 우리나라는 급속한 고령화 현상으로 인해 체계적이고 정책적인 만성질환관리가 절실하다. 특히, 나이에 따라 꾸준히 증가하는 고혈압에 대한 효과적인 관리를 위해 연령대에 따른 위험요인을 분석하는 것은 중요하다. 따라서 개인적 노후준비 뿐만 아니라 전반적인 사회복지수준 향상 및 노인복지대책을 통해 질병에 대한 관리가 필요하다.

  • This study aimed to explore the factors affecting the foreign direct investment (FDI) intentions of investors into Quang Ninh province, located in the north-eastern of Viet Nam. Researchers used two main methods, namely, Exploratory Factors Analysis (EFA) and the Structural Equation Model (SEM) based on partial least squares structural equation modeling (PLS SEM) to explore and measure the impact of factors affecting the investors' FDI intentions into Quang Ninh province. The empirical analysis used data from the survey of 206 domestic and foreign investors into Quang Ninh province, including representatives of the Board of Directors, members, and management representatives at the department level, with reliable tools (SPSS 26 and SmartPLS 3.0 software). The research results identified the following factors affecting investment into Quang Ninh: FDI attraction policies have the strongest impact on the investors' FDI intentions; it is followed by infrastructure, public services and human capital with strong effects on intentions of investors' FDI; and finally the standards of living that affects the investors' FDI intentions. There is also a positive relationship between all the factors and the investors' FDI intentions. Several recommendations are further suggested to enhance attraction of foreign direct investment into Quang Ninh province.

  • Purpose: This study was descriptive survey research to examine the factors affecting menopause, depression and menopausal symptoms, and the relations among these factors in South Korean midlife women. Methods: The subjects were 319 midlife women in Daegu City. Measures were Zung's Self-Report Depression Scale (1979) to check depression, and the Midlife Women's Symptom Index developed by Im (2006) to check menopausal symptoms. Data were collected from June 1 to July 31, 2010. Collected data were analyzed by mean, standard deviation, and Pearson's correlation coefficient through SPSS/WIN 18.0. Results: There was a statistically significant correlation between depression and menopausal symptoms (r=.692, p<.001). The factors affecting depression were age (r=.194, p<.001), income (r=-.307, p<.001), exercise (r=-.602, p<.001), and menopausal status (r=.224, p<.001). The factors affecting menopausal symptoms were exercise (r=-.158, p<.037), menstrual pain (r=-.171, p = .004) and menopausal status (r=.222, p<.001). Conclusion: Intervention programs for decreasing menopausal symptoms in midlife women should be focused on relieving menopausal pain and encouraging excise from youth. Further studies will be needed to examine the relations among other factors including living style, area and menopausal symptoms.
