To improve the prognosis of mitral valve replacement surgery, analysis and evaluation of pre and intra operative risk factors will be very much valuable. Author studied 205 cases of mitral valve replacement from Feb 1982 to June 1989 for the risk factors of hospital death. 90 patients were male and 115 were female, and age was from 16 to 59 years, Mitral stenosis dominant lesions were 91 cases and regurgitation 114. Suspected risk factors were NYHA functional class, cardiothoracic ratio, implanted valve type and size, operation time, age and sex, thrombus in left atrium, atrial fibrillation, aortic cross clamping time, left ventricular end diastolic and systolic dimension, nephropathy, hepatopathy and respiratory insufficiency. Statistic analysis was performed by X2 test between survivors and death group. Statistical significances as pre and intraoperative risk factors of hospital death after mitral valve replacement were confirmed in those presence of AF on the EKG, NYHA functional class[>IV], cardiothoracic ratio[>70%], and implanted valve size[>33mm]

Purpose: The purpose of this study was to examine risk factors for sexual behaviors in Korean female high school students. Methods: Data was collected by a written questionnaire from June 22 to July 18, 2002 from 522 girls, who were stratified samples from a target population of 63,375 11th grade students from 200 regular high schools and 70 vocational high schools in Seoul, Korea. We conducted multiple regression analysis using the SAS pc＋ program. Results: Risk factors for intimate behaviors were association with boy friends, differential association, family attachment, and family abuse experience. These variables cause 68% of intimate behaviors. Risk factors for sexual experiences were differential association, association with boy friend, and family attachment. These variables cause 14% of sexual experiences. Conclusion: Efforts to reduce sexual behaviors in girls should include the possible role of peers and develop peer leader programs.

In this review, we have provided an overview of the environmental risk factors for attention deficit hyperactivity disorder (ADHD), focusing on the major environmental toxicants related to the disorder. Researchers have indicated that since the characteristics of ADHD are complex, the disorder’s etiology involves multiple genes of moderate effect interacting with environmental factors. The possible roles of prenatal and perinatal exposure have been the main focus of research on environmental risk factors for ADHD. Among environmental toxicants, we reviewed the potential effects on the development of ADHD of exposure to lead, nicotine, alcohol, polychlorinated biphenyls (PCBs), and dioxin. Further, for the each neurotoxicant, clinical prevention or intervention strategies aimed at reducing a child’s risk from environmental toxic insults have been presented.

The Outsourcing Industry has grown swift pace and evolved over time, and the Global IT Outsourcing market has shown signs of a steady growth. In the Korean company, however, IT Outsourcing is not active as that of the advanced countries and there is lack of literature to understand the characterristics of IT Outsourcing in the Korean company. This paper, therefore, analyze the outcomes surveying 65 compaanies in Korea to investigate how IT Outsourcing risk factors affects IT Outsourcing intention. Based on our literature reviews bassed on number of key articles, journals, and the focus group interviews, IT Outsourcing risk factors are proposed into four different domains: Transaction, Client, Vendor, Environment perspectives. It found that one factor(Vendor perspectives) is closely related to the IT Outsourcing intention of the Korean company. Finally, this paper analyzed the pros and cons of IT Outrcing offers a guide to the risk factors.

Purpose: This study was done to determine inpatient fall rates in an acute hospital setting and to explore risk factors and characteristics across clinical departments. Methods: The medical records and standardized fall reports of 416 patients admitted between January 1 and December 31, 2012 were reviewed. Descriptive statistics and statistical tests were used, including: t-test, ${\chi}^2$-test, ANOVA. Results: The total fall rate per 1,000 inpatient days was 0.49. Fall rate, fall risk factors and characteristics such as age, type of fallers and mean MFS (Morse Fall Scale) differed significantly among clinical departments. Conclusions: The analysis results show that the fall rates, fall risk factors and characteristics of acute hospital inpatient falls varied significantly across clinical departments. The findings of this study suggest that hospitals should consider differences in fall related characteristics across clinical departments when implementation fall prevention strategies and interventions.

Objectives : To express an opinion on the controversy about the cold exposure as one of the risk factors of Bell's palsy. Results & Conclusions : It is widely assumed that there is a causal relationship between Bell's palsy and herpes family virus. Regarding cold exposure as one of the risk factors of Bell's palsy, however, some physicians do not accept that cold exposure could be one of the risk factors of Bell's palsy. There is no evidence supporting the hypothesis that the virus causes Bell's palsy, and it has yet to be confirmed. As there are some experimental and clinical reports suggesting that Bell‘s palsy is related to the cold exposure, we cannot exclude the possibility that the cold exposure may be one of the important risk factors of Bell's palsy. It would be necessary to undertake further studies to determine this.

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.

Dementia is a clinical syndrome characterized by progressive impairment of cognitive and functional abilities. As currently applied treatments for dementia can only delay the progression of dementia and cannot fundamentally cure it, much attention is being paid to reducing its incidence by preventing the associated risk factors. Cardiovascular and metabolic diseases are well-known risk factors for dementia, and many studies have attempted to prevent dementia by treating these risk factors. Growing evidence suggests that sex-based factors may play an important role in the pathogenesis of dementia. Therefore, a deeper understanding of the differences in the effects of drugs based on sex may help improve their effectiveness. In this study, we reviewed sex differences in the impact of therapeutics targeting risk factors for dementia, such as cardiovascular and metabolic diseases, to prevent the incidence and/or progression of dementia.
