Purpose: To develop end-of-life care training programs for nurses who provide in a tertiary hospital, we examined the mediating effects of empathy and resilience on the relationship between their stress and job performance. Methods: This study was conducted with 218 participants at a hospital in B city in South Korea from August 15 through August 30, 2017. Data collected from the participants were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and multiple regression using the IBM SPSS/WIN 21.0 software. Results: Terminal care stress was found to be negatively correlated with empathy competence (r=-0.345, P<0.001), resilience (r=-0.223, P=0.001) and terminal care performance (r=-0.260, P<0.001), whereas empathy (r=0.467, P<0.001) and resilience (r=0.358, P<0.001) were positively correlated with terminal care performance. Empathy had a complete mediating effect (${\beta}=0.409$, P<0.001) on the relationship between terminal care stress and performance, and resilience a partial mediating effect (${\beta}=0.294$, P<0.001). Conclusion: Based on the findings of this study, development of training programs with a focus on empathy and resilience are highly recommended to improve job performance of nurses who provide terminal care in a tertiary hospital.

This study was a descriptive correlational study investigating the mediating effects of resilience in the relationship between depression and rehabilitation motivation in middle-aged stroke patients. There was a total of 185 middle-aged patients aged 40 to 64 years, who were diagnosed with stroke at a university hospital and rehabilitated at three local hospitals located in S city and four hospitals in U city. The data were collected using a self-reported questionnaire between the 1st and 31st of December in 2016. The data were analyzed using t-test, ANOVA, Pearson's correlation coefficient, and step-wise causal method using SPSS/WIN 22.0 statistical program. To test the statistical significance of the mediation effect, PROCESS and bootstrapping were used. The mean age of the subjects were $56.26{\pm}6.37$ years. There were 70.3% male subjects, an average depression level was $21.21{\pm}7.09$, an average resilience was $25.52{\pm}9.63$, and rehabilitation motivation was $47.44{\pm}5.87$. Depression was negatively related to resilience and rehabilitation motivation. However, resilience and rehabilitation motivation have a static correlation. These results confirmed that resilience appears to be a complete mediating effect in the relationship between depression and rehabilitation motivation. Therefore, it is important to develop a resilience enhancement program to improve the motivation of rehabilitation for stroke patients.

The purpose of this research is to examine the factors influencing on worker's job-satisfaction analyzing the influence of emotional support from fellow workers, resiliency of self-efficacy, stress and job-performance. A total of 456 completed questionnaire, consisted of small business workers 253 (male 89, female 164) and middle school teachers 203 (male 44, female 159). The questionnaire showed relatively high reliability, with Cronbach α ranging from .83 to .91. The results of the path analysis and effect analysis showed very similar pattern in the group of small business workers and middle school teachers. Based on the path analysis, emotional support from fellow workers had a positive influence on the workers resiliency of self-efficacy. Consequently, the enhanced resiliency of self-efficacy increased the job-performance, however decreased the stress, which in turn contributed to increase the job-satisfaction significantly. Based on the effect analysis, resiliency of self-efficacy showed the most big size of positive total effect to worker's job-satisfaction, followed by job-performance and emotional support. On the other hand, stress showed negative effect on job-satisfaction.

This study examines the influence of parental social support and resiliency of efficacy on stress, depression and stress management behavior. A total of 799 participants (male=386, female=413), consisting of 184 elementary school, 354 middle school, 274 university students completed a questionnaire that included Rhode Island Stress Scale (Horiuchi, Tsuda, Tanaka, Yajima & Tsuda, in press), Stress Management Behavior Scale (Evers, Prochaska, Johnson, Mauriello, Padula & Prochaska, 2006), Becks' Depression Inventory (BDI-II, Beck, Steer & Brown, 1996; CES-D, Radloff, 1977), Resiliency of Efficacy (Bandura, 1995), and Parental Social Support (Kim & Park, 1999). The results of path analysis are as follows. First, resiliency of Efficacy had a direct and negative effect on stress and depression and direct positive effect on stress management. Second, stress management behavior did not have any influence on stress. Third, parental social support had a direct and positive effect on resiliency of efficacy. This pattern of results were found for elementary school, middle school and university students. When depression was measured by CES-D Scale (Center for Epidemiological Study of Depression) parental social support and resiliency of efficacy had a different parental of influence on stress, depression and stress management behavior, pointing out the importance of conducting comparative analysis of various measures of depression.

Recently web services ale being used to provide environments of distributed computing. Web services provide reusable software component. So, one web service can be used by many users, and one user can use different web services. For reliable use of web services, in these cases, it is important to be fault-tolerance. Existing fault-tolerant methods in web services need a kind of client modification and cannot consider extensible factors like quality. This study suggests the system architecture and description language for the system which can improve some of these problems.

Corrective control compensates the stable-state behavior of asynchronous sequential machines so that the closed-loop system can be changed in a desirable way. Using corrective control, we present a novel fault tolerance scheme that overcomes permanent faults for asynchronous sequential machines. When a permanent fault occurs to an asynchronous machine, the fault is not recovered forever while the machine is irreversibly stuck in a set of failure states. But, if the machine has control redundancy in the limited behavior range, corrective control can be applied to solve the fault tolerance problem against permanent faults. We present the condition on detecting permanent faults and the existence condition of an appropriate corrective controller. The design procedure for the proposed controller is described in a case study.

The Mobile IP protocol allows IP hosts to move between different networks without changing their IP addresses. The Mobile IP systems supporting the local registration were introduced to reduce the number of times when a home registration with the remotely located Home Agent is needed. The local registration Mobile IP protocol enhanced the performance by processing the MN\`s registration requests at a local agent. However. the local registration approach may consider other aspects of the Mobile IP systems as the FA fault tolerance. In this paper, we will briefly review previous protocols to support the FA fault tolerance in hierarchical local registration Mobile If system and will propose a fault tolerance protocol with backup FA in hierarchical local registration mobile IP t() enhance the efficiency of such systems against Foreign Agent failures.

국내 창업 생태계는 최근 몇 년 사이에 양적으로 급속히 팽창하였다. 정부 또한 가장 시급한 문제로 일자리 창출을 꼽고 이에 대한 해결방안 중 하나로 창업지원을 대폭적으로 확대하며 중소기업에 대한 지원확대를 제시하고 있다. 이러한 배경 하에 창업의 양적 성장은 위에서 설명한 바와 같이 가시적으로 나타나고 있다. 하지만 창업기업의 양적확대라는 긍정적인 측면에도 불구하고 창업기업의 낮은 생존율은 개선의 시급함을 나타내고 있다. 국내 창업기업 10곳 중 7곳 이상이 창업 5년 이내에 폐업을 하고 있는 상황이다. 이와 같은 이유로 2015년부터 중소벤처기업부는 창업기업의 데스밸리(Death Valley) 극복 및 성과창출을 위해 창업 후 3년 이상 7년 이내 기업을 대상으로 자금 및 서비스를 지원하는 등 창업기업이 어려움을 극복하고 사업 지속 가능성을 높이기 위하여 다양한 노력을 하고 있다. 본 연구의 목적 역시 창업자가 사업을 진행하면서 겪는 어려움을 극복하는 요인과 사업지속의지가 어떠한 상관관계를 가지고 있는가를 조사하고 분석하는데 있다. 본 연구에서는 사업 어려움 극복영향 요인(창업자 역량, 지원시스템)이 사업지속의지에 미치는 영향에 관한 연구를 경영성과의 매개 역할과 사회적 지지의 조절 역할을 하는지를 중심으로 진행하였다. 따라서 본 연구에서는 창업자 역량과 지원시스템이 경영성과를 증진하고, 증진된 경영성과가 사업지속의지에 영향을 미칠 것이라는 인과적 경로를 검증하고자 한다. 사회적 지지를 조절변수로 설정하여 본 연구를 진행하였다.

The present study focused on frustration emotion investigated the variables evoking frustration and the process in which sense of frustration would be overcome, and explored the principle of aesthetics the consumers under the frustration might prefer in choosing goods. The results of this study are as follows. First, consumers usually felt frustration rather than anger when it became obvious that their objectives could not be met and that they failed to achieve their objectives due to uncontrollable cause. Second, consumers who felt frustration wanted to receive emotional support and comfort from close acquaintances rather than to cope actively with the unsuccessful situation by renewed challenges. Third, consumers, once frustrated, preferred harmony principle rather than emphasis principle in terms of esthetics in choosing design of goods. Therefore, marketing managers are advised to approach to the consumers who felt frustration on the basis of harmony principle in design of goods.
