The purpose of this study was to identify the meaning of performance experienced in the process of practicing at the elderly suicide prevention center. Therefore, the actual results perceived from the subjective viewpoints of the chiefs, staff and service users from the public institutions, which offer the elderly suicide prevention services were examined. The results classified the service provider's view, service users view and multi-dimensional view. The research method is a case study of qualitative research method. The results of the study found that the analysis commonly perceived from the perspectives of both the chiefs and staff from the public institutions offering elderly suicide prevention service were 'the perception of structural obstacles during the process of practicing the services and focused on the achievement of experiencing changes in the service users and the community'. On the other hand, the analysis from the perspective of the service users turned out to be 'focusing on changes in the users'internal perception according to service experiences'. The meaning and essence of the analytical results perceived from each perspective are summarized as follows. First, the analytical results perceived of the chiefs of public institutions offering elderly suicide prevention service were 'the process in which the identification of the institution is rediscovered through the service'. Second, the analytical results perceived by the staff from the institution were 'being acknowledged in the community and organization while experiencing changes in the service users in the process of struggling to survive in such community and organization'. Third, the analytical results perceived by the service users were 'holding on to the lifeline at the edge of a precipice'. Based on the results, political and practical implications of elderly suicide prevention service were discussed.

For the effective development of high qualitative software, it is important to measure the "design quality" through the "process of design" which is the upper phase of software development. And based on it, to improve the "design quality" is also important. But, up to now, most of the researches have been in connection with the quality characteristics, and quality sub-characteristics that can be measured and evaluated by users, but the researches about the internal characteristics and metrics that can be measured and evaluated by developer in the process of the development have not been through going enough. Accordingly, the purpose of this research is to point out the problems included in the internal characteristics of the solution of these problems. Omissions and duplications of the internal characteristics can be prevented by arranging than newly according to the model suggestion. Furthermore, it is confirmed that developers can get the efficiency of measurement by metrics, and also can get good improvement effect of metrics measurement accuracy through the concrete application test.

In this paper, we design MHEG engine that can generate MHEG objects and present It to the users in Multimedia/Hypermedia Applications In the MHEG engine, the transmitted MHEG objects decoded into internal format. For the easy interpretation of MHEG objects, we define internal format as to be matched for each MHEG object. We easily processobjectinformation using the tree data structure because object inheritance and possession can be represented in tree structure. Object inheritance and possession must be represented in the internal format because they used in resolving the reference to external objector data file. The presentation synchronization extracts the synchronization information from MHEG composite objects, representing and controlling heterogencous media associated to spatio- temporal relation. In order to exactly represent the spatio-temporal synchronization included into MHEG composite object, we propose the algorithm that processes synchronization using the message of the synchronization module and the internal objects. MHEG engine proposed in this paper may be basic technology fro multimedia application area using Korea New Net.

The article is devoted to analyzing the police influence on road safety formation. The globalization processes confirm the study's relevance, provoking population mobility and the need to increase freight traffic. The study aims to identify the factors that affect road safety and the activities of the police and the EU transport safety units. An empirical analysis using factor analysis, correlation analysis, and general scientific methods of cognition were carried out to achieve the goal. The analysis results found that the number of police officers affects road safety, but not in all countries, which confirms the importance of other factors. Based on the analysis results of the scientific literature, the factors affecting transport safety are legislative regulation, the use of innovative technologies, transport infrastructure, geography, and psycho-physical and emotional drivers factors. It has been proved that the police authorities and units cannot fully ensure transport safety in the European Union because the safety is formed by a complex of actions by the state and road users.

Background and Objectives: Beta-blockers (BBs) improve prognosis in heart failure (HF), which is mediated by lowering heart rate (HR). However, HR has no prognostic implication in atrial fibrillation (AF) and also BBs have not been shown to improve prognosis in heart failure with preserved ejection fraction (HFpEF) with AF. This study assessed the prognostic implication of BB in HFpEF with AF according to discharge HR. Methods: From the Korean Acute Heart Failure Registry, 687 patients with HFpEF and AF were selected. Study subjects were divided into 4 groups based on 75 beats per minute (bpm) of HR at discharge and whether or not they were treated with BB at discharge. Results: Of the 687 patients with HFpEF and AF, 128 (36.1%) were in low HR group and 121 (36.4%) were in high HR group among those treated with BB at discharge. In high HR group, HR at discharge was significantly faster in BB non-users (85.5±9.1 bpm vs. 89.2±12.5 bpm, p=0.005). In the Cox model, BB did not improve 60-day rehospitalization (hazard ratio, 0.93;95% confidence interval [95% CI], 0.35-2.47) or mortality (hazard ratio, 0.77; 95% CI, 0.22-2.74) in low HR group. However, in high HR group, BB treatment at discharge was associated with 82% reduced 60-day HF rehospitalization (hazard ratio, 0.18; 95% CI, 0.04-0.81), but not with mortality (hazard ratio, 0.77; 95% CI, 0.20-2.98). Conclusions: In HFpEF with AF, in patients with HR over 75 bpm at discharge, BB treatment at discharge was associated with a reduced 60-day rehospitalization rate.

Background: Vitamin K antagonist (VKA) to prevent thromboembolism in non-valvular atrial fibrillation (NVAF) patients has limitations such as drug interaction. This study investigated the clinical characteristics of Korean patients treated with VKA for stroke prevention and assessed quality of VKA therapy and treatment satisfaction. Methods: We conducted a multicenter, prospective, non-interventional study. Patients with $CHADS_2{\geq}1$ and treated with VKA (started within the last 3 months) were enrolled from April 2013 to March 2014. Demographic and clinical features including risk factors of stroke and VKA treatment information was collected at baseline. Treatment patterns and international normalized ratio (INR) level were evaluated during follow-up. Time in therapeutic range (TTR) > 60% indicated well-controlled INR. Treatment satisfaction on the VKA use was measured by Treatment Satisfaction Questionnaire for Medication (TSQM) after 3 months of follow-up. Results: A total of 877 patients (age, 67; male, 60%) were enrolled and followed up for one year. More than half of patients (56%) had $CHADS_2{\geq}2$ and 83.6% had $CHA_2DS_2-VASc{\geq}2$. A total of 852 patients had one or more INR measurement during their follow-up period. Among those patients, 25.5% discontinued VKA treatment during follow-up. Of all patients, 626 patients (73%) had poor-controlled INR (TTR < 60%) measure. Patients' treatment satisfaction measured with TSQM was 55.6 in global satisfaction domain. Conclusion: INR was poorly controlled in Korean NVAF patients treated with VKA. VKA users also showed low treatment satisfaction.

Purpose: The aim of this study is to identify the expectations and perceptions of health center users as to the services. SERVQUAL scale was used for measurement of service quality. The purpose of this study is to offer baseline data for improving the quality of health care services. Methods: The subjects were users of a health center in S City in Kangwon-do; 170 people participated in this study. Results: Regarding service quality depending on general characteristics, the following results were obtained. First, there were statistically significant differences depending on the gender, purpose of visit, and satisfaction in the health center. Second, the services fell short of the expectations. Third, the quality of 'safe, accurate services' scored the highest, while 'empathy and friendliness' scored the lowest. Fourth, 'internal, external environment of the health center' scored the highest, while 'courtesy of staff' scored the lowest. There were no statistically significant differences. Conclusion: Based on the findings, the following are suggested. First, employee education should be provided for development of empathy and interaction with patients; those are the weakest areas in the health care services. Second, a system allowing patients to understand and participate in their treatment should be developed.

Healthcare is one of the biggest industries that consume IT Infrastructure as a necessity. A reliable reach to secure private information is the essential goal. Most of the healthcare organizations either have their own custom solutions developed or third part CRM software tailored to their needs. This culture satisfies the usability internal to the organization but lacks the ability to provide public access to the users or even to take a step ahead and collaborate with like minded institutes for research and potential growth. Emergence of cloud computing has provided us the opportunity to take a step ahead and build applications available to users on a secure platform, with ability to scale the resources depending on the requirements. The effective use of hybrid and community cloud can create rock solid foundations for healthcare IT Infrastructure. These cloud deployment models not only caters the present needs of healthcare IT Infrastructure but also opens the possibilities to build applications and provide secure and reliable access beyond the limits of organizational boundaries.

Various stakeholders within and outside of the organization are involved and participate in the outsourced IS development. As their interests and goals are different conflict arises in the process of their interaction, and it is an important factor affecting outsourcing success. The study focuses on the conflict between client users and vendor, i.e. main conflict in the outsourcing project, and examines the relationship of conflict with project success, the antecedents of conflict, and investigates the effectiveness of conflict resolution facilitation. An integrated conceptual model is developed grounded on is outsourcing, IS development, project management, and organizational behavior literature. Nine specific hypotheses on the conflict in outsourcing projects are proposed, and data collection and analysis are performed with 214 ISD outsourcing projects. Results indicated that the conflict between client users and vendor in outsourcing projects was found to have negative effects on project success. Main causes affecting conflict were examined, and relative influences of these causes were clarified. Recently internal IT personnel have been faced their role change with the increase of outsourcing, and the importance of their conflict resolution facilitation was highlighted.
