In general, a large-scale wireless sensor network(WSNs) is composed of hundreds of or thousands of sensor nodes. In this large-scale wireless sensor networks, it is required to maintain and manage the networks to lower management cost and obtain high energy efficiency. Users should be provided with sensing service at the level of quality for users through an efficient system. In evaluating the result data quality provided from this network to users, the number of sensors related to event detection has an important role. Accordingly, the network protocol which can provide proper QoS at the level of users demanding quality should be designed in a way such that the overall system function has not to be influenced even if some sensor nodes are in error. The energy consumption is minimized at the same time. The protocol suggested in this article is based on the LEACH protocol and is a role-based self-Organization one that is appropriate for large-scale networks which need constant monitoring.

In LTE-Advanced that different networks coexist, it is considered that it is actually difficult to provide service continuity with a procedural and static control method applied to the existing voice service. This paper suggests Service Self-Organization to support the service continuity effectively based on SON. It means a method in which a subscriber's terminal collects information about its current condition and base station around, and a base station, through the data collected by monitoring inner or adjacent base station, shares related data and converges, controlling service continuity on its own. In other words, as context information of mobile terminal and base station changes, set-up of related functions such as ISHO, cell selection, source allocation, load control, and QoS mapping is adapted; each function fits into the change, exchanges the process of reorganization, and interacts; these actions go toward to satisfy service continuity. Simulation results show that it provides better performances than the conventional one with the measure of resource utilization rate and outage probability.

Purpose - This study examines the relationships between leader-member exchange (LMX), perceived fit, organization-based self-esteem (OBSE), corporate citizenship, work engagement, and employees' negative word-of-mouth (NWOM). In particular, it analyzes the effect of the interaction between LMX and corporate citizenship on OBSE, and the effect of the interaction between perceived fit and corporate citizenship on OBSE. Finally, this study analyzes moderated mediation by legal/ethical citizenship and philanthropic citizenship, and work engagement in the LMX-NWOM relationship and the perceived fit-NWOM relationship, respectively. Design/methodology - The research data were collected through a questionnaire from 293 employees working at 117 restaurant companies in Korea. Findings - The results were as follows. First, both LMX and perceived fit were negatively related to employees' NWOM. Second, both LMX and perceived fit were positively related to OBSE. Third, OBSE was negatively related to employees' NWOM. Fourth, legal/ethical citizenship and philanthropic citizenship were found to attenuate the positive (+) relationship between perceived fit and OBSE, respectively. Fifth, it was found that work engagement weakened the negative (-) relationship between OBSE and NWOM. Finally, OBSE was found to have a partial mediating effect moderated by corporate citizenship (legal/ethical citizenship and philanthropic citizenship) and work engagement in the relationship between perceived fit and NWOM. Originality/value - This study makes a theoretical contribution by expanding the mechanisms associated with LMX and NWOM by revealing the mediating effect of OBSE in their relationship. Additionally, this study makes a theoretical contribution in that it demonstrates the importance of enhancing legal and ethical citizenship and philanthropic citizenship by revealing the moderating effect of corporate citizenship in the relationship between perceived fit and OBSEE. Finally, it makes a theoretical contribution by suggesting that the interaction between work engagement and OBSE is important in reducing employees' NWOM by revealing the moderating effect of work engagement.

The purpose of this study was to determine the empirical cause-effect relationships among business ethical values and person-organization fit, job satisfaction, turnover intent, and organizational performance within family restaurants and feeding facilities. Self-administered questionnaires were completed by 459 restaurant employees. The SPSS and Amos programs were then applied to the data to perform frequency, factor, reliability, correlation and SEM analyses. The primary results are as follows. First, business ethical values had a significant positive effect on person-organization fit. Second, person-organization fit had a significant positive effect on job satisfaction, and a significant negative effect on turnover intent. Third, job satisfaction had a significant positive effect, and turnover intent had a significant negative effect, on organizational performance. Finally, upon verifying the possible direct and indirect effects of business ethical values within family restaurants and feeding facilities, it was determined that the ethical values had significant direct and indirect effects on person-organization fit, job satisfaction, turnover intent, and organizational performance. These findings have various implications. For example, an improved in-house ethical working environment leads to greaterperson-organization fit, and having employees that feel there is better in-house ethical reliability leads to greater consistency between personal and organizational values, resulting in higher job satisfaction and ultimately organizational performance.

The purpose of this study is to apply to the phenomenological self-evaluation method in the social welfare agency. It means that the phenomenological self-evaluation method accepts "the reality" which occurs in the social welfare setting, and functions for the social worker to play dual role of practitioner-evaluator. This paper examines two dimensions of social work evaluation theory and practice. Firstly, this study is to investigate a trend of evaluation in social work setting, and seeks theoretical aspect of phenomenological self-evaluation method, with emphasis on the strength and limit of the positivism evaluation methods. Although qualitative evaluation was suggested to make an alternative to the positivism by qualitative researchers, they did not suggest the specific methods and roles of the practitioner-evaluator. In this study, two directions of the phenomenological self-evaluation method are suggested to overcome the limitations. which are "environment-relation self-evaluation" and "program-oriented self-evaluation". Secondly, the result of phenomenological self-evaluation studies for the social welfare community center program and organization in kangnam district from June, 1994 (Program-oriented self-evaluation) to march, 2000 (Environment-relation self-evaluation) are presented. the phenomenological self-evaluation study showed the expected outcome such as; reflective self-training, making a practice knowledge, enhancing service quality, and reinforcing the identity of social welfare profession.

This study is an argument that Yeoheon Jang Hyun Gwang's Yeok-Hak-Do-Seol has been on the context of the typical Confucian methodology of self-organization for a sage's or superman's character (爲己之學) and completed the methodology. Therefore the context from Confucius to Southern Song China Era is argued as a context of development and systematization of the methodology. In addition the fact that Zhuxi(朱熹) and his students had systimatization of the methodology with the publications of some important textbooks is also explained. The most stressed thing of this study is Yeoheon's Yeok-Hak-Do-Seol is just the text that succeeded them as the methodology of self-organization and had a special purpose of completion of the methodology not only with comprehensive items of practice but also intuition into the human's life and the world by his mastery of Yeokhak(易學). The viewpoint this study keeps is the Confucian methodology of self-organization is considered for the purpose of development and upholding the Confucian truth, and thus the methodology itself has been regarded as the necessary one that is the closest approximation to a pursuit of Confucian truth. According to this viewpoint we can observe the features of methodology of the pursuit of Confucian truth from the Yeok-Hak-Do-Seol. However the Yeok-Hak-Do-Seol has its purpose merely on a human being's self-organization but also on an enormous enterprise to make the universe peace or sustainability of the world. His stress on the enterprise shows that his methodology is not a merely repetition of the tradition of the Zhuzixue but a creative deveopment of the tradition. The other feature is that his methodology is systematization on the basis of Yeokhak, or the study of Yi-jing(易經). The main method he intensified is easiness and simplification that is the main point which he extracted from Yi-jing as the most important and necessary way of life.

This study is a case study of the process of emerging for creative products to lead world science and technology. The aim of the study is to understand the emerging process of scientific creative products, and is to provide the direction of gifted education that discovers and trains globally competitive science talents through this. To discuss the emerging process of creative products, this study has academically discussed the creativity of the complexity of dealing with theory of evolution, the real life settings, and self-organization of experience etc., and has methodologically adopted the qualitative research method through a case study to look at the structures and processes. Data collection has been formed through a discussion with 12 Korean scientists who have created selected creative products, greatly contributed for the world science and technology(12 areas). The analysis has been carried out by the latter part positivist methods. As a result, the emerging process of creative products in the field of science and technology were separated into four steps: (1)the foundation stage of knowledge, (2)the exploration stage of knowledge, (3)the construction stage of knowledge, and (4)the emerging stage of knowledge. Each stage has been revealed growing up through the macro-system and the self-organization of each micro-systems.
