The purpose of this study was to identify the effect of nutrition related factors on mortality risk among community-residing older adults in Korea. We analyzed data from 8,532 older adults who took part in the 2008 living profiles of older people survey and 2011 death mortality data. According to Cox regression analysis, male (Hazard Ratio [HR], 2.03; 95% Confidence Interval [CI], 1.74~2.37), diabetes mellitus (HR, 1.35; 95% CI, 1.12~1.64), underweighted (HR, 2.68; 95% CI, 2.16~3.31), dysphagia (HR, 1.23; 95% CI, 1.02~1.47), chewing ability (HR, 1.33; 95% CI, 1.11~1.59), and undernutrition (HR, 1.47; 95% CI, 1.23~1.75) significantly affected mortality risk. Systematic nutrition support programs should be developed to decrease the mortality among Korean older adults.

This study was to identify differences in mortality risk by living arrangements among older adults. We analyzed data from 3,827 older adults who took part in the 2014 Korean Longitudinal Study of Aging. Cox proportional hazards regression was used for data analysis. The significant factors associated with mortality risk in living with others were male, education level, self-rated health, limitation of instrumental activities of daily living, cognitive dysfunction, and depression. The significant factors associated with mortality risk in living alone were regular exercise, limitation of instrumental activities of daily living, and cognitive dysfunction. This study is significant in that it examined whether there are differences between mortality risk by living arrangements. According to the results of this study, nursing intervention should be developed to decrease mortality by living arrangements.

This study was attempted to investigate the possible association of osteoarthritis with the metabolic syndrome (MetS) and its components in Korean adults based on the Korean National Health and Nutrition Examination Survey (KNHANES). The prevalence of MetS was significantly increased in OA group in women. To investigate the association between the components for MetS and osteoarthritis, we analyzed the mean values of 5 components of MetS, waist circumference (WC), triglyceride (TG), HDL-cholesterol, systolic blood pressure, and fasting plasma glucose in normal and OA group. In women, WC, TG, HDL, and systolic blood pressure were associated with the development of OA. Moreover, accumulation of components of MetS was significantly related to the prevalence of OA in Korean men and women. These data suggest that MetS might be a novel risk factor for OA and MetS should be taken into account in the prevention and treatment of OA for Korean adults as well.

This study aimed to identify the effect of chronic mind-body function decline on health-related activities of daily living. Data collection was surveyed using interview and questionnaires by 148 subjects in a general hospital located in Seoul from June 8 to July 13, 2011. The results were as follows: First, based on exercise habit, patient group who do exercise regularly showed in male(26.7%) and female(22.7%), respectively. The risk ratio of it was 0.25 times. On the other hand, control group who do exercise regularly showed in male(42.2%) and female(31.8%), respectively. The risk ratio of it was 0.61 times. Secondly, the risk ratio of social factor in male was 45.18 times(p=.04) while the risk ratio of physical factor in female was 237.1 times(p=.001). In conclusion, to prevent declining of chronic mind-body function, it is necessary to solve stress through sound life rhythm maintenance, immunity enhancing food intake and continuous exercise.

The purposes of this study were to examine the effects of carebidet robot during defecation on incontinence associated dermatitis, pressure ulcer risk and biological markers in critical care patients. Data were analyzed using t-test, Chi-square test, Fisher's exact test, Mann-Whitney U-test and Repeated measures ANOVA. There was a significant difference in incontinence associated dermatitis, pressure ulcer risk, and improving biological markers between the two groups, and there were significant changes over time and the group by time interactions. The findings of the study demonstrated that carebidet robot during defecation was more effective than the current usual care in reducing incontinence associated dermatitis, pressure ulcer risk, and improving biological markers in critical care patients.

Nowadays, the number of patients committing suicide due to depression and stress is rapidly increasing. In addition, if stress and depression last for a long time, they are dangerous factors that can cause heart disease, brain disease, and high blood pressure. However, no matter how modern medicine has developed, it is a very difficult situation for patients with depression and heart disease without special drugs or treatments. Therefore, in many countries around the world, studies are being actively conducted to determine patients at risk of depression and patients at risk of suicide at an early stage using electrocardiogram, oxygen saturation, and brain wave analysis functions. In this paper, in order to analyze these problems, a computer simulation was performed to determine heart disease risk patients by establishing heart disease hypothesis data. In particular, in order to improve the predictive rate of heart disease by more than 10%, a simulation using fuzzy inference was performed.

Korea, which has the highest pedestrian fatality rate among OECD countries, is making efforts to improve the safe walking environment by enacting laws focusing on pedestrian. Spatial clustering was conducted with scan statistics after examining the social network data related to traffic accidents for children and seniors. The word cloud was used to examine people's recognition Campaigns for children and literature survey for seniors were in main concern. Naedang and Yongsan are the regions with the highest relative risk of weak pedestrian for children and seniors. On the contrary, Bongmu and Beomeo are the lowest relative risk region. Naedang-dong and Yongsan-dong of Daegu Metropolitan City were identified as vulnerable areas for pedestrian safety due to the high risk of pedestrian accidents for children and the elderly. This means that the scan statistics are effective in searching for traffic accident risk areas.

The purpose of this study is to consider the characteristics perceived by users who utilize MyData services in the financial sector. It aims to examine how these factors influence users' understanding for sustained usage and their resistance to innovation. The research seeks to explore the relationship between users' awareness of characteristics and its impact on both enhancing comprehension for continued usage and addressing users' resistance to innovation. Utilizing a specialized survey agency, we examined the relative effects of innovation resistance factors, such as relative advantage, perceived risks, complexity, clarity and perceived ease of use on MyData service users. Furthermore, this research focuses on employing empirical analysis to validate the relationships between these factors through the survey. The findings of this study suggest that MyData service should dedicate ongoing efforts to minimize user resistance to service utilization. Specifically, it was revealed that among the innovation resistance factors, perceived ease of use, relative advantage, perceived risk, and complexity exert influence in that order.

원전 안전등급 계측제어계통이 디지털화 되고 있으나 안전계통을 소프트웨어로 구현하는 과정에는 소프트웨어 공통모드고장(Common Mode Failure)과 같은 위험 요소가 존재한다. 일반 산업체와는 달리 원전에서 발생하는 사고는 일반 공중에게 방사능 누출 가능성을 내재하고 있어 디지털 안전계통은 원자로를 안전하게 정지시키는 것을 보장하고, 방사능이 누출되는 사고에 대해서도 그 피해를 최소화시키거나 방지할 수 있는 기능을 확보해야 한다. 이와 같은 원전 안전계통 디지털화의 성공과 원전의 안전성을 확보하기 위해서는 소프트웨어 신뢰성과 안전성 확보가 관건이며 안전-필수 소프트웨어 검증 기술개발이 절실히 요구된다. 본 기고에서는 원전 디지털 안전-필수 소프트웨어에 대한 개발방법과 규제요건, 규제방법 및 규제대처방법 등에서 공통적으로 고려해야 할 안전-필수 소프트웨어 개발 및 검증의 기술적 측면과 안전-필수 소프트웨어의 개발 및 검증의 각 단계에 대해서 기술한다.

This research addresses the experimental application of the digital close-range photogrammetric technique for 3D deformation measurement and visualization of road slope. The 3D displacements were extracted by the photo-triangulation based on the bundle adjustment method using the digital imagery. In addition, we produced the digital elevation models, the digital orthorectified images and the 3D perspective view images of the slope employing a digital photogrammetric workstation. Also the inclination map of the slope was generated as the data for monitoring and managing dangerous slopes.
