The purpose of this study was to identify the relationship between leisure function, self-esteem and social role loss among golf players in the middle age. Furthermore, it was meaningful to provide basic data on leisure activities and healthy retirement preparation through golf at the present time of the aging society. The subjects of study who adults were recruited from Seoul, Gyeonggi-do. For the data processing, it conducted frequency, reliability, confirmatory factor, correlation, and structure equaling modeling analyses. The results were as follows; First, leisure function of middle age golf participant had a positive influence on self-esteem(p<.05). Second, leisure function of middle age golf participant had a positive influence on social role loss(p<.05). Third, self-esteem of middle age golf participant had a positive influence on social role loss(p<.05). Forth, self-esteem mediated the relationship between middle age golf participant leisure function and social role loss.(p<.05).

One of fundamental problems in developing robust distributed services is how to achieve distributed consensus agreeing some data values that should be shared among participants in a distributed service. As one of algorithms for distributed consensus, Raft is known as a simple and understandable algorithm by decomposing the distributed consensus problem into three subproblems(leader election, log replication and safety). But, the algorithm dose not mention any types of dynamic configuration of participant peers such as adding new peers to a consensus group or deleting peers from the group. In this paper, we present a new consensus algorithm named Raft-D, which supports the dynamic configuration of participant peers by extending the Raft algorithm. For this, Raft-D manages the additional information maintained by participant nodes, and provides a technique to check the connection status of the nodes belonging to the consensus group. Based on the technique, Raft-D defines conditions and states to deal with adding new peers to the consensus group or deleting peers from the group. Based on those conditions and states, Raft-D performs the dynamic configuration process for a consensus group through the log update mechanism of the Raft algorithm.

Objective: The literature on participant roles in bullying lacks empirical evidence to explicate what differentiates latent participation. The purpose of the present study was to examine social cognition in early adolescents (i.e., empathy, prosocial moral reasoning, and perceived group norm) with latent participants of bullying. Methods: The participants included 279 adolescents (129 girls; M age = 13.5 years) in two middle schools. Results: The result showed that empathy, prosocial moral reasoning, and perceived group norm were possible determinants of latent bullying. First, high levels of empathy (especially empathic concern and perspective taking) was associated with latent defenders. Second, helping decision of prosocial moral dilemma and prosocial moral reasoning were associated with complex situational cues. Third, latent reinforcer positively indentified the group norm with regard to bullying. Conclusion: The results are discussed in terms of practical implications for anti-bullying programs and educational practitioners.

The "stamp rally" is an event that participants go the round with predetermined points for the purpose of collecting stamps. They bring the stamp card to these points. They, however, sometimes leave or lose the card. In this case, they may not reach the final destination of the stamp rally. The purpose of this research is the construction of the stamp rally system which distinguishes each participant with his or her hand instead of the stamp card. We have realized our method distinguishing a hand posture by the image processing. We have also evaluated it by 30 examinees. Furthermore, we have designed the data communication between the server and the checkpoint to implement our whole system. We have also designed and implemented the process for the registering participant, the passing checkpoint and the administration.

Security of a power system refers to its robustness relative to a set of imminent disturbances (contingencies) during operation. The socially optimal solution for the actuall level of generation/consumption has been well-known spot pricing at shot-run marginal cost. The main disadvantage of this approach arises because serious contingencies occur quite infrequently. Thus by establishing contractual obligations for contingency offering before an actual operation time through decision feedback we can obtain socially optimal level of system security. Under probabilistic precontract pricing the operating point is established at equal incremental cost of the expected short-run and collapse cost of each participant. Rates for power generation/consumption and for an offer to use during a contingency, as well as information on the probability distribution of contingency need for each participant, are derived so that individual optimization will lead to the socially optimal solution in which system security is optimized and the aggregate benefit is maxmized.

Purpose: This study was to explore health experiences of the low-income elderly living alone reflected in Newman's Health as expanding consciousness theory. Method: The researcher used Newman's praxis methodology because it is good for showing the process of interaction between the researcher and the low-income elderly living alone. Results: The significant characteristics of early health experience during a participant's lifetime were demonstrated that blamed themselves, being burden of themselves hopeless of their lives. However, after a turning point in health experience. The health experience of most of the participants evolved as expanding consciousness. Conclusion: This study has provided support for Newman's theory of health. Most of the participants recognized meanings in their patterns and authentic caring relationships with the nurse as researcher, pattern recognition as a nursing practice was a meaningful transforming process in the participant-nurse partnership. This participatory approach expands the scope of sharing health experience with the elderly living alone and with caring community people.

This paper develops a portfolio management game applicable to Korean Stock Market with an emphasis on teaching and training aid. It allows each participant to start out with a certain amount of money and pick his favorable stocks from a list of stocks chosen by instructor. Each participant must make a transaction at each time period and he gets a readout that states his individual performance, i.e., stock lists, cash on hand, net worth, transactions he has made and rank in accordance with his net worth. This game package consists of 10 subprograms and 7 files written with Fortran language for use on the Nova 840 computer and is divided into 3 main categories according to their functions, i.e., book-keeping function, data processing function and information searching function. This package may be used for training portfolio decison makings in the stock market and for comparing various investment methods through hypothetical investments.
