노인 운전자는 기능저하로 인해 사고 위험성이 증가하지만 스스로 변화를 점검하는 자가-조절 능력 또한 발달한다. 이에 실제 노인 운전자가 운전 능력과 위험성 변화에 대응하는 특성에 대한 정보는 노인의 운전 능력 평가 현장과 연구에 의미있는 근거를 제공할 수 있다. 따라서 본 연구의 목적은 한국 노인 운전자의 운전 위험성 자각 특성을 운전 중 행동과 운전관련 기능변화의 측면에서 분석하여 노인 운전자 평가를 위한 기초 자료를 제공하는 것이다. 지역사회에 거주하는 노인 운전자 500명을 대상으로 자가-보고식 평가를 실시하고 노인 운전자의 운전 위험성 자각 징후를 분석하였다. 그 결과 다수의 노인 운전자가 시각 및 청각이 저하되거나 운전 여건 변화에 적응하는데 어려움을 느낄 때 운전 위험성을 자각하는 특성이 있음을 확인하였다. 반면, 약물 복용이나 간질, 발작, 의식손실 등 의학적 건강 상태 변화에는 둔감하게 반응하는 특성이 확인되었다. 본 연구 결과가 고령화가 가속화되는 한국의 노인 운전자 안전 관리에 기여할 수 있기를 기대한다.

Purpose: The aim of this study was to explore characteristics of and risk factors for accidental inpatient falls. Methods: Participants were classified as fallers or non-fallers based on the fall history of inpatients in a tertiary hospital in Seoul between June 2014 and May 2015. Data on falls were obtained from the fall report forms and data on risk factors were obtained from the electronic nursing records. Characteristics of fallers and non-fallers were analyzed using descriptive statistics. Risk factors for falls were identified using univariate analyses and logistic regression analysis. Results: Average length of stay prior to the fall was 21.52 days and average age of fallers was 61.37 years. Most falls occurred during the night shifts and in the bedroom and were due to sudden leg weakness during ambulation. It was found that gender, BMI, physical problems such elimination, gait, vision and hearing and medications such as sleeping pills, antiarrhythmics, vasodilators, and muscle relaxant were statistically significant factors affecting falls. Conclusion: The findings show that there are significant risk factors such as BMI and history of surgery which are not part of fall assessment tools. There are also items on fall assessment tools which are not found to be significant such as mental status, emotional unstability, dizziness, and impairment of urination. Therefore, these various risk factors should be examined in the fall risk assessments and these risk factors should be considered in the development of fall assessment tools.

Purpose - This study examines the effect of corporate debt characteristics on the relationship between anti-takeover provision and the cost of debt. Design/methodology/approach - The study analyzes a sample of non-financial firms listed on the stock market with December fiscal year-end from 2011 to 2018. Debt default risk (debt size, liquidity ratio, interest coverage ratio, loss occurrence) and the issuance of bonds are utilized as measures of corporate debt characteristics. Findings - First, it is observed that creditors of firms with anti-takeover provision demand higher returns as the debt default risk of these firms increases. Second, for firms issuing bonds, it is found that bondholders in companies with anti-takeover provision also seek higher returns. Research implications or Originality - This study contributes by demonstrating that the effect of anti-takeover provision on creditors can vary depending on corporate debt characteristics. Particularly, the study highlights the importance of a firm's debt default risk and creditor distinction (bondholders vs. regular creditors) as significant factors that may influence perceptions of anti-takeover provision.

Purpose: This study aimed to identify latent classes based on major modifiable risk factors for coronary artery disease. Methods: This was a secondary analysis using data from the electronic medical records of 2,022 patients, who were newly diagnosed with coronary artery disease at a university medical center, from January 2010 to December 2015. Data were analyzed using SPSS version 20.0 for descriptive analysis and Mplus version 7.4 for latent class analysis. Results: Four latent classes of risk factors for coronary artery disease were identified in the final model: 'smoking-drinking', 'high-risk for dyslipidemia', 'high-risk for metabolic syndrome', and 'high-risk for diabetes and malnutrition'. The likelihood of these latent classes varied significantly based on socio-demographic characteristics, including age, gender, educational level, and occupation. Conclusion: The results showed significant heterogeneity in the pattern of risk factors for coronary artery disease. These findings provide helpful data to develop intervention strategies for the effective prevention of coronary artery disease. Specific characteristics depending on the subpopulation should be considered during the development of interventions.

Purpose: The objective of the present study was to evaluate the effects of occupational exposure to low dose organic solvents on the prevalence of cardiovascular risk factors. Methods: Study design was retrospective cohort study subjected on 191 exposures and 118 controls working in a petrochemical manufacture company. The eight indicators related to CVD risk were followed up for five years from 2008 to 2012. The risk level was compared during the follow up years and subject's characteristics, and the change of risk level were analyzed with repeated measures ANOVA and multiple logistic regression analysis. Results: At the start year 2008, the rate over cutoff value (ROCV) of BS (p<.001) and mean systolic BP (p=.017) were higher in organic solvent exposure group and the others showed no difference. And by the subject's characteristics, odds ratio of the ROCV of BS were higher in organic solvent exposure group and work shift group as 2.51 and 3.07. Comparing the results in 2012 to those of 2008, cardiovascular disease risk in organic solvent exposure group was about 1.5 times higher than that of in the control group. Conclusion: Gradual increase in the CVD risk was identified in organic solvent exposure group. However, the risk might be influenced by shift work and bad behaviors rather than organic solvent exposure.

The purpose of this study is to investigate the impact of internal control on credit risk of joint stock commercial banks in Vietnam from 2007 to 2018. Furthermore, we specify bank-specific characteristics and macroeconomic conditions, and analyze how these factors affect credit risk of banks: the number of board members, the number of board members with banking or finance background as ratio of total board members, loans to total assets ratio, loans to deposit ratio, the number of days between the year-end and the publication of the financial statements, and the use of top four auditing firms proxy for five elements of internal control. By using the dataset of 30 Vietnamese joint stock commercial banks and Bayesian linear regression via Random-walk Metropolis Hastings algorithm, the results of this study show that five elements of internal control have a impact on bank credit risk, namely, control environment, risk assessment, control activities, information and communication, and monitoring activities. For factors of banks' characteristics, bank size and financial leverage have a negative impact on banks' credit risk, and bank age has a positive effect. For macroeconomic factors, inflation has a positive impact and economic growth has a negative impact on banks' credit risk.
