1) Purpose : The purpose of this research is to identify the trend of job stress of hospital nurses based on last 10 years of domestic research and to suggest directions for systematic future research. 2) Methodology : 101 studies between 2006 and 2016 were selected using key words such as registered nurse and job stress from Academic Information Service(Riss4u), the National Assembly Library and Korean studies Information Service System(KISS). 3) Findings : The researches on job stress of hospital nurses were increasing. The result showed that job stress increased for shift nurses. Especially, nurses of small-medium sized hospital showed remarkable effects to organization such as turnover intention. In addition, although the importance of approach to management is emphasized, there is little research on these aspects. 4) Practical Implications : It is necessary to develop systematic research on job stress directly effecting turnover intention of hospital nurses from hospital management aspect. The development of job stress measuring tools reflecting the characteristics of the medical institution, and the human resources management plan to resolve the imbalance in manpower for nurses should be required.

The food service industry has grown up without an affection of economic collapse, and its kinds are being diversified and focused on many different aspects from physical taste to many other elements such as atmosphere, service quality, sanitation and etc.. Now it appeals to even familiarity. These Facts are well ref looted to Family Restaurant which has not been very popular so far, but now it takes its space in the market, and its management system is being introduced to other countries. The purpose of this study is to see how to satisfy them to make maximum business profit, and one possibility is "incentive". To accomplish research, theoretical and practical studies have been done and surveys have taken placed for substantial studies. The subjects were limited to employees in Family Restaurant in Seoul from February 20th to March 20th, 2001. Data, reliableness, and propriety were analyzed by SAS(Statistical Analyzed System). Sampling mode was randomness, and validation mode was limited to 223 papers. The followings are the results of this analysis First, Satisfaction of incentive were made by stability, impartiality and suitability regardless difference on companies, ages, departments, and authority of an employees. Second, Satisfaction on incentive for employees in Family Restaurants were not well received. Although these necessary demand, there is not yet incentive system operation to most of business. Especially, it is not even studied on Family Restaurants. This study should have been studied on more customers and spotted employees to be objective. It is strongly recommended to do this study without limitation and further studies is considered on this subjects.

The purpose of this study is to propose and test a model of customer retention in Internet shopping malls when switching barriers and comprehensive customer value exist in terms of economic and experiential aspects. The literature about customer retention propose that switching barriers are important factors other than satisfaction influencing customers' intention to remain with a specific supplier. The switching barriers mean anything that makes customers' defection difficult or costly and are consisted of perceived switching costs, attractiveness of alternatives and virtual relationships. The Customer Value Scale by Mathwick(2001) is applied to this study as economic value, shopping efficiency, service excellence, aesthetic appeal and playfulness(Zeithaml, 1988; Holbrook, 1994). The analyses showed partial support for the affirmative effect of customer values and switching costs and full support for the affirmative Influence of satisfaction on repurchase intention in the Internet shopping mall environment. But the attractiveness of alternatives and virtual relationship did not have a significant Influence like the result of Jones(1998)'s study of the service industry.

In recent years, the predominant part in telecommunications is mobile communications. The next generation network is extending today's voice-only mobile networks to multi-service networks. ATM Network is possible to carry such multi-media traffic and it will be expect to use wireless ATM for the future mobile access network. One of manly important aspects for the performance of wireless ATM is the Medium Access Control (MAC) protocol. The MAC protocol must be able to satisfyingly handle the different ATM services (CBR, VBR, ABR and UBR) with their radically different performance requirements. Additionally, the MAC protocol must be able to cope with the complex radio environment where fading, multi-path propagation interference and burst-errors further complicate the situation. In this paper, a dynamic slot allocation algorithm in wireless ATM is proposed for an efficient channel sharing/media access at the MAC layer. We use equivalent capacity in the allocation of slots for VBR traffic which is variable along the time. It is simple and effective slot allocation method for VBR service. In particular, we consider the slot allocation of a session consisted of several connections for requirement of multimedia traffic. Simulation shows that the cell loss ratio is reduced by re-allocation of extra slots in Mobile Terminal (MT).

Delay, delay variation and packet loss rate are principal QoS(Quality of Service) elements of packet communication. This paper proposes a new buffer allocation mechanism to improve the packet loss performance in such a situation that multiple logical buffers share a single physical memory buffer. In the proposed buffer allocation mechanism, the movement of dynamic threshold follows a curved track instead of a straight line which is used in the DT(dynamic threshold) mechanism. In order evaluate the effectiveness of the proposed mechanism, it is compared with the existing previously proposed mechanisms in several aspects including NC(no control), ST(Static Threshold) and DT mechanisms.

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.

The purpose of this study was to examine the influence of long-term care insurance(LTCI) settlement on life satisfaction of female caregivers for the elderly. In September of 2013, we conducted a survey of 300 female subjects over 65 years old living in Jeonju. For empirical verification, ${\chi}^2$, t-test and regression under control of socio-economic variables were applied to determine whether LTCI settlements changed the level of life satisfaction of female caregivers. First, the results showed that caregivers who were not covered by LTCI had higher healthy life satisfaction than those covered with LTCI. Second, life satisfaction of female caregivers is higher when income and education levels are higher. Third, LTCI settlement did not affect five sub factors of caregivers' life satisfaction. The results suggested that LTCI policy should cover not only the insured but also caregivers'physical and mental aspects.

Objectives : This study investigates the association between weather conditions and the rate of no-shows at an academic medical center. Methods : Electronic data regarding medical appointments atover the course ofone academic year (2016.03~2017.02) were used for analysis. Characteristics of weather conditions and the daily number of no-shows were compared by Chi-square test. A logistic regression was run to determine if certain aspects of weather affected the rate of no-shows. Results : The results reveal an overall no-show rate of 6.8% that appears to vary in accordance with specific weather conditions. Lower average temperatures, in particular, corresponded with a higher rate of no-show patients. This may indicate that o-show rates in autumn and winter can be expected to exceed those during spring. Conclusions : This study investigates the association between no-show patients and weather conditions, and offers suggestions for augmenting this loss. One recommendation is to begin conducting investigations nationwide in order to provide more useful information.

This study examines the differences in the various characteristics of the firms along their growth stage based on the survey data of 2,515 Korean ventures. Venture characteristics include KSFs(Key Success Factors), environment attributes of their product markets, CEO roles, the use of OPR(Other Peoples Resource). Growth stage of the ventures are classified by their dominant management problems: foundation, the market launch of the first proprietary product or service, The Outset of second generation product or service, and the Initial Public Offering (IPO) and stabilization. The results of this study show substantial differences in many aspects among firms at different growth stages. Although common KSFs exist, KSFs are changing as the venture evolves. Differences in KSFs and environmental attributes along growth stage require CEO to do different role in business process. Different kinds and amounts of external resources are needed according to their growth stage. However, almost all of external resources are offered to ventures in later stage. Entrepreneurs need to change their role, as their firms grow, from visioning and strategic role to marketing and production emphasized role. Based on the results, this study suggests a number of new government policies and future research ideas. Other implications and limitations of this study are also noted.
