We propose a novel user-perceived performance optimization framework for the Android platform that takes advantage of the user-centric response time analysis. To this end, we propose a new definition of response time, which we call the user-centric response time, as a metric for the quality of user-perceived performance of the smartphone application. In this paper, we describe the design and implementation of an on-line user-centric response time analyzer for Android-based smartphones, which provides smartphone application developers with valuable insight for user-perceived performance optimization. We implemented the user-centric response time analyzer on the Android platform, version 4.0.4 (ICS) running on a Galaxy Nexus smartphone. From our experimental results, the proposed user-centric response time analyzer accurately estimates user-centric response times with an accuracy of 92.0% compared to manually measured times with less than 1% performance penalty. In order to evaluate the efficiency of the proposed framework, we were able to reduce the user-centric response time of the target application by up to 16.4% based on the evaluation results by the proposed framework.

급격한 고령화 시대에 노년층의 사회참여욕구가 확대되고 있으나 어떻게 해야 하는지를 모르고 있어 지역사회의 사회참여 프로그램에 대한 인지도가 매우 낮고 제도나 프로그램에 대한 접근성이 제한적인 실정이다. 가족기능이 해체된 노인을 대상으로 노후 생활 지원욕구에 발맞춰 경제적지원, 취업지원, 의료지원, 여가지원 등 각종 복지 서비스를 제공함으로써 보편적이고 일상적인 생활을 영위하도록 지원하고자 많은 노력을 하고는 있으나 이를 체계적으로 실시할 수 있는 모델이 부족한 것이 현실이다. 이에 본 논문에서는 노인들의 역할 및 지위 상실로 인하여 가정에서 고립된 생활을 하는 노인을 대상으로 복지 전문가가 현장에서 비교적 손쉽게 적용할 수 있는 체계화된 모델을 제안함으로 생활스트레스 감소, 인지기능 향상, 우울증 감소, 생활만족도를 향상시키고 노인여가 문화에 대한 건전성 확산을 통해 건강한 노후생활을 영위하게 하며 문화생활 지원을 통해 사회적 비용 부담 경감을 도모함과 동시에 자존감의 고취 및 자율성을 획득하고 자아성취감과 만족감을 느끼게 하는데 있다.

This study identifies the moderating effects of cognition on the relationship between self-care confidence and self-care behavior in the diabetic elderly. The participants were 205 elderly subjects with diabetes, who visited a citizen health center located in D city, Korea. Data were collected from 20th April to 31st August 2015, and were analyzed by t-test and multiple regression. Our results reveal no significant differences between the depressive and non-depressive groups, when considering diabetes self-management confidence, knowledge, behavior and cognitive function. Cognitive function had a moderating effect in the relationship between self-care confidence and self-care behavior only in the depressed group. Our results indicate that it is therefore necessary to apply individual nursing intervention based on cognitive function and depression level, and to develop various programs for improving the cognitive function and depression amongst the diabetic elderly.

The purpose of this study was to evaluate effects of oral health education for occupational health nurses. The subjects were 300 occupational health nurses which participated in continuing education of Korean Association of Occupational Health Nurses. Oral health education contents consisted of basic knowledge about oral health, prevention of periodontal disease, oral health care for workers, and oral health program for workers. In order to evaluate the effects of oral health education, we performed questionnaire surveys before and after the education regarding their perceived oral health status and concern for oral health, knowledge about prevention of periodontal disease, attitude about oral health promotion, and needs for implementation of oral health promotion program. The data were analyzed by paired t-test to compare the change of knowledge and attitude according to the education. Linear regression analysis was carried out to assess the factors related to the improvement of their knowledge and attitude. The findings indicated that oral health knowledge and attitude of occupational health nurses were significantly improved by oral health education. A factor of the improvement of knowledge and attitude was concern for oral health. And they would like to be provided primarily oral health education for occupational health nurses. Finally, this study suggested that oral health education for occupational health nurses had significantly effects on improving oral health knowledge and attitude.
