  • Nomogram is useful for predicting the prevalence of each patient through the scoring system without a complex formula. Because there are few studies on chronic otitis media (COM) in adults, this study aims to identify the relevant risk factors for COM in Korean adults and to build a nomogram for the risk factors. The Health Interview Survey data subset, derived from the Sixth Korean National Health and Nutrition Examination Survey (KNHANES VI), was used to evaluate the participants. Of the participants, the weighted prevalence of COM was 5.3%. Residence, earphone use, atopic dermatitis, allergic rhinitis, chronic rhinosinusitis, and subjective hearing status were identified as risk factors for COM. Using 6 risk factors, we propose a nomogram for COM, and use AUC to verify the discrimination of the nomogram.

  • In the era of the 4th Industrial Revolution, smart technology being considered to improve productivity breakthroughs is in the spotlight as a means to replace traditional construction technology in the construction industry. However, various problems are occurring in construction sites using smart technology and causing negative impacts on construction projects. Therefore, the objective of this study is to identify risk factors that occur when smart technologies are used in construction projects. To achieve this purpose, this study investigated the difficulties at construction projects using smart technology, and risk factors were derived based on site surveys and literature. The risk factors were measured by experts, and then a total of 19 risk factors was derived by exploratory factor analysis. As a result, risks were classified as 5 factors, the institutional factor is the most difficult response, and the government needs anticipative system improvement and a long-term plan. The research findings provide practical implications for construction experts trying to apply smart technology in construction sites and construction policy-makers to revitalize smart technology.

  • The purpose of this study is to improve the level of records management by enhancing the risk management in university archives. Through surveys and post-interviews, the current status of risk management in university archives was investigated, the results of the investigation were analyzed to identify problems and limitations in risk management in university archives, and the following suggestions for improvements were made. First, the legal effects of risk management should be strengthened in the Public Records Management Act, and matters related to risk management should be stipulated. Second, the National Archives of Korea should actively intervene to identify problems in risk management in university archives and provide appropriate support for problem-solving. Third, the identity of university archives as independent organizations should be secured for the implementation of professional and active records management tasks. Fourth, standards and manuals reflecting risk management practices for university archives should be prepared. Fifth, a sufficient budget must be secured to meet all necessary requirements for risk management. Lastly, cooperation in the performance of records management and risk management tasks should be achieved by raising awareness of university archives and their records management tasks among the heads of the institutions and members of the organizations.

  • Drought occurs extensively over a long period and causes great socio-economic damage. Since drought risk consists of social, environmental, physical, and economic factors along with meteorological and hydrological factors, it is important to quantitatively identify their impacts on drought risk. This study investigated the relationship among drought hazard, vulnerability, response capacity, and risk in Chungcheongbuk-do using a structural equation model and evaluated their impacts on drought risk using Bayesian networks. We also performed sensitivity analysis to investigate how the factors change drought risk. Overall results showed that Chungju-si had the highest risk of drought. The risk was calculated as the largest even when the hazard and response capacity were changed. However, when the vulnerability was changed, Eumseong-gun had the greatest risk. The sensitivity analysis showed that Jeungpyeong-gun had the highest sensitivity, and Jecheon-si, Eumseong-gun, and Okcheon-gun had highest individual sensitivities with hazard, vulnerability, and response capacity, respectively. This study concluded that it is possible to identify impact factors on drought risk using regional characteristics, and to prepare appropriate drought countermeasures considering regional drought risk.

  • We aimed to estimate the prevalence of high-risk human papillomavirus (HPV) infections in women of high socioeconomic status (SES) in Seoul, Republic of Korea and to identify risk factors. This study included 13,386 women visiting a prestigious healthcare center located in Seoul between 2003 and 2008. High-risk HPV infections were detected in 994 (7%) and the age-standardized prevalence was 8%. Abnormal Pap smear results ${\geq}$ atypical squamous cells of unknown significance (ASCUS) were observed in 280 of 12,080 women (2%). Based on univariate analysis, age, level of education and number of children were associated with high-risk HPV infections. Based on multivariate analysis, age and high-risk HPV infections had an inverse relationship. In women with high SES in Seoul, the prevalence of high-risk HPV infection was 7% and the age-standardized prevalence was 8%. Age was a strong determinant of high-risk HPV infection.

  • Purpose: This study aimed to investigate the factors that increase fall risk in the residential environment and the perceived fall risk among community-dwelling elderly through comparisons between fallers and non-fallers. Methods: The subjects were 95 community-dwelling elderly aged 65 years and over residing in the metropolitan city of Ulsan. A structured questionnaire consisting of items on sociodemographics and health- and fall-related characteristics was used and data were collected from July to August 2015. The data were analyzed with the SPSS/WIN program. Results: Among recent fallers, 38.9% had diagnosed diseases when the fall occurred, 56.87% were fearful of a recurrent fall, and 86.5% stated that they were increasing their carefulness but that had led to a decrease in activity. There were significant differences between elders who had fallen at least once and elders who had no falls in age, health status, depression, the experience of falling, fear of falling, diseases, and medications. Conclusion: The results indicate a need to assess risk factors to identify older adults with a high risk for falling and the need to develop multifactorial intervention programs that consider both environmental and perceived risk factors as well as physical risk factors to reduce and prevent falls among the elderly.
