This study purports to investigate the determinant of job satisfaction among workers working at Long-term care hospitals. The independent variables contain three groups of determinants: organizational characteristics variables(job autonomy, job variety, distributive justice, role conflict, supervisor support, job suitability, job significance, job security, organizational support, job growth, promotional opportunity), environmental variables(job opportunity), and psychological variables (met expectation, job efficacy, positive affectivity, and negative affectivity). The sample used in this study consisted of 250 workers from 4 Long-term care hospitals nationwide. Data were collected with self-administered questionnaires and analyzed using multiple regression analysis. The results of the study are as follows: 1) the following variables, listed in order of size, have significant effects on job satisfaction: negative affectivity(-), job significance(+), job growth(+), age(+), positive affectivity(+), organizational support(+), job opportunity(-). 2) the variance of job satisfaction explained by the variables used in the study are 53.8%. When demographic variables added to Model I, job satisfaction explained by variables are 55.4%. 3) the results of this study indicate that three variables of negative affectivity, job significance, job growth are especially important for improving the level of job satisfaction among workers at Long-term care hospitals.

The functions of urban park including health related benefit and climate adaptation and mitigation are expanding. However, in-depth research and discourse on the equitable distribution of expanded park function has been limited so far. Following research suggests Green Welfare concept to reflect distributive equity and multifunctionality in the process of urban park policy development and execution. This study developed park welfare indices to analyze disparities of neighborhood urban park(NUP) distribution viewed from green welfare by literature review. The findings analyzed through the Correlation Analysis and Cluster Analysis by SPSS 18.0. The results of the study are as follows. First, green welfare is defined as "to receive equitable benefits and participate in the delivery process of green services which are promoting health and securing safety from climate change risks for every citizen by life cycle regardless of socioeconomic status". Second, NUP per person in Seoul indicate meaningful differences by socioeconomic and environmental status of Seoul administrative districts. Park welfare indices correlated to NUP per person were shown population density(negative), percentage of individuals $aged{\geq}65$(positive), percentage of self-reliance of local finance(positive), flood and air pollution vulnerability by climate change(negative). Third, the cluster analysis identifies three significant clusters that indicate differences of park welfare level. Thus, it was found that NUP in Seoul from a green welfare perspective was provided disproportionately. Future urban park policy in Seoul was required equitable distribution of multifunctionality of park beyond quantitative expansion, and priority consideration should be given to park service consumer.

Mobile Ad Hoc Networks (MANETs) are self-organized networks that do not rely in their operation on wired infrastructure. As in any networking technology, security is an essential element in MANET as well, for proliferation of this type of networks. But supporting secure communication in MANETs proved to be a significant challenge, mainly due to the fact that the set of nodes in the network can change frequently and rapidly and due to the lack of access to the wired infrastructure. In particular, the trust model and the authentication protocols, which were developed for wired and infrastructure-based networks, cannot be used in MANETs. In [1], we addressed the problem of efficient authentication of distributed mobile users in geographically large networks and proposed a new authentication scheme for this case of MANETs. The proposed scheme exploits randomized groups to efficiently share authentication information among nodes that together implement the function of a distributive Certification Authority(CA). In this paper, we analyze numerically the performance of authentication method using randomized groups and compare with the simulation result.

This study is about service failure and recovery. Prior studies of service failure and recovery encounters have been limited to descriptive research based primarily on retrospectiveti.e., memory-based) self-reports. This study uses a survey method and utilize a 2*2*2 experimental design with service recovery scenarios across two services. Manipulations included two levels of controllability, two levels of procedural justice and interactional justice, and two levels of distributive justice. Accordingly, this research examines how the controllability of service failure affect recovery satisfaction, and how these relations are moderated by the justice of service recovery. Conclusively, bi-dimension(outcome and process) constitutes the service recovery and this result supports the insistence that even dissatisfied customers can be satisfied through the service recovery efforts of the organization that once failed to meet the needs and expectation of customers.

The purpose of this study was to investigate the effects of distributive and procedural justice on organizational effectiveness and the mediating role of supervisor trust among the MICE industry employees. For the study, data were collected from 303 MICE industry employees in metropolitan area by self-administered questionnaires. Collected data were analyzed using structural equation modeling technique. The results of this study showed that organizational justice had effects on organizational effectiveness measured in terms of job satisfaction, organizational commitment and organizational citizenship behaviour of MICE industrial employees and that supervisor trust mediated the relationship between organizational justice and organizational effectiveness. Based on the results of this study, the theoretical implications of the findings were discussed and directions for future research were advanced.

The purpose of this study was to investigate the determinants of intent to leave among IT industry employees, based on the Price's structural model of employee turnover. The sample used in this study were composed of 370 employees from 10 IT firms located in Seoul and Gyeonggi-Do. Data were collected with self-administered questionnaires and analyzed using structural equation modelling technique. This study found that four task reward variables(job variety, job autonomy, job challenge, and role ambiguity), two social reward variables (supervisory support and coworker support), three organizational reward variables(promotional chances, job security, and distributive justice) and one environmental variable(job opportunity), had significant effects on IT industry employees' intent to leave in terms of total effects and his directions of those significant effects were consistent with theoretical predictions; and that two mediating variables, job satisfaction and organizational commitment had the most important effects on IT industry employees' intent to leave in terms of total effects. The theoretical and practical implications of the research findings were discussed and the directions for future research were suggested.

After Marx, the issues regarding human labour have been the alienation towards production means and the distributive justice. Fourth industrial revolution and development of AI(Artificial Intelligence) opened the possibility of a independent production and economy system absolutely excluding against human nature and labour. Using robots and AI will deepen demarcation between living things and one not having life, separating the intelligence from the consciousness. At present, so called pre-stage of post human, seeking interests for life, new social relationship and new community will be increased as well. We can understand that interests for small community, self-sufficiency, dailiness, food and body in this context is increasing too. Representative trend towards this cultural phenomena is called as the 'Kinfolk culture.' Work-life balance, 'Aucalme', 'Hygge', 'So-Hwak-Haeng'(a small but reliable happiness) are the similar culture trends as. Vital capitalism, presented by O-Yong Lee, seeks focusing onto living things principles, e.g. 'topophilia', 'neophilia', and 'biophilia' as the dynamics looking for the history substructure, not class struggle and conflicts. He also argues the 'Vital Capitalism' be regarded as a new methodology to anticipate a social system after post human era. G. Deleuze said "arts is another expression method for existential philosophy. It gives a vitality onto philosophy and gives a role to letting abstract concept into definite image." We can find a lot cases arts' imagination overcomes critical point of scientific prediction power in the future prediction. This paper reviews ideas and issues of 'vital capitalism' in detail and explorers imaginating initial ideas of vital capitalism in the film 'Little Forest.'
