Purpose: This study was conducted to examine psychological empowerment and awareness and performance of Healthcare-Associated Infections(HAIs) control among Intensive Care Unit (ICU) nurses. Method: The data for this study were collected using structured questionnaires from 178 nurses working in the ICUs of four hospitals with more than 500 beds. Results: The subjects'psychological empowerment, awareness and performance of HAIs control were mean over. The subjects'psychological empowerment showed statistically significant differences depending on age, marital status, academic background, clinical career, ICU career, and position and experience in infection control among their general characteristics. Awareness of HAIs control showed statistically significant differences depending on age, gender, marital status, clinical career, and ICU career. Performance showed statistically significant differences depending on age, gender, marital status, and, ICU career. Regarding the subjects' performance of HAIs control, there was a statistically significant positive correlation between psychological empowerment and awareness. Conclusion: It was found that it is necessary to strengthen differential customized training according to the subjects'characteristics for effective HAIs control, and to strengthen the nurses'awareness of HAIs control through systematic evaluation, monitoring, and feedback, as well as continuous education and training.

The purpose of this study was to evaluate performance and subjective satisfaction of mobile phone's interface elements considering the elderly users. First, mobile phone's interface elements were outlined recent foreign and domestic studies. Then, final three mobile phone's interface elements were determined by expert rating, AHP analysis, and questionnaire analysis. Objective and subjective measures were then used to determine the effects of several specific design parameters and aging differences on performance of mobile phones. In this experiment, 38 subjects and 4 independent variables were used to measure task completion time and user's subjective satisfaction. The statistical analyses indicated significant aging differences between older people and younger people in terms of keypad type and bell sound level in performance. Significant aging differences were also found for user subjective satisfaction. It is suggested that some major results from this study be used to develop mobile phone design guidelines that are more usable and accessible for most users, particularly for older users.

The purpose of this study is on the performance evaluation of horizontally installed HGHEX(Horizontal-type Geothermal Heat Exchanger) in the summer season and the winter season. Followings are the results. By the result of data acquisition at the site, $2.5{\sim}2.7^{\circ}C$ temperature differences are gained between supply pipes and return pipes of HGHEX in the summer season. And $0.5{\sim}1.5^{\circ}C$ temperature differences are gained from HGHEX in the winter season. With these temperature differences, heat quantity of rejection and absorption is calculated and the performance of HGHEX is evaluated according to the seasons.

The purpose of this study was to investigate the impact of two different SNS-based tasks on university students' English writing performance. To address our primary research question, Me2day, microblogging and Social Networking Service, was employed. 43 university students were divided into two experimental groups depending on the task types: a comparison task group and a sharing personal experiences task group. The main findings of the study were as follows: first, two different types of SNS-based tasks, 'spot the differences' and 'writing diaries', had a positive effect on learners' writing performance. The reason for this was that the succinct messages limited to 150 characters made it easier for the students to try writing in English without burden; and they may benefit from their peers by seeing their posts and interacting with each other. Yet there were no significant differences between the two groups when it came to the degree of improvement. Second, two different types of SNS-based tasks differently fostered certain aspects of the writing performance; 'contents knowledge' was supported by the 'writing diaries' task and range was supported by the 'spot the differences' task. Third, learners in the two experimental groups mostly had positive impressions regarding usage of Me2day as a new learning tool.

This paper applies the technology-gap trade theory to explaining radical changes in the competitive positions of countries in world machine tool markets over the last three decades. It develops the notion that the innovation gaps in machine tools among countries led to the inter-country differences in the competitive performance in the sector as well as in its user sectors. Since competitive advantage largely depends on a capability to improve, create and apply technology to market competition, a higher innovative performance in one country than another is closely related to a higher innovative performance. A higher innovative performance in machine tools is also associated with a higher competitive performance of the large areas of its user sectors, due to sectoral interdependences and externalities generated by machine tool innovations. The results of empirical investigation through a panel data analysis show that the international gaps in machine tool innovations appeared to have a positive significant relationship with the differences in the export performance of both the machine tool sector and its user sector across countries.

This study was conducted to find out effect of dynamic balance performance in normal adult when obscuring vision in half of the both eye and to prepare the basic data treatment of brain damage patient with visual field deficit. The subject for this study included 40 healthy right-handed and 20 left-handed were dynamic balance performance when obscuring vision in half of the both eye. who age from 20 to 30 years in normal adult without neurosurgical orthopedic, performance balance disability or other medical disorders.

The purpose of this study was to examine the relationships between the community business, performance and the life satisfaction of local residents and to investigate the mediating effects that community business performance has on the life satisfaction of local residents. The results of the study investigating the effect of community business, performance and the residents' life satisfaction mediating effect of performance are summarized as follows: First, there were differences with the economical, environmental, and performance factors pertaining to the participants' age while there were no differences concerning the social-cultural factors and the life satisfaction of local residents. Second, the higher the impact a community business has, the higher the life satisfaction of the local residents have. In addition, the higher the performance in community business, the more ready local residents are to be inclined to be satisfied. Third, economical and environmental factors have direct effects on the life satisfaction of local residents, but also indirectly effect the performance of local residents. In addition, the level of performance that a community business plays has a mediating role in the life satisfaction of local residents.

This study distinguished innovation activities into 3 main things (sustainability management activity, management innovation activity and quality innovation activity). Performance differences among those 3 innovation activities are again distinguished into 4 things (affecting on sales revenue, increasing productivity, improving its corporate image and cost reduction) to demonstrate recognition of performance. We also demonstrated difference of performance between manager and other workers.
