  • Purpose - Today, the importance of the service industry has increased. Social welfare businesses that follow the non-profit principle have neglected the distribution of the service. However, an intangible service, when produced and consumed, has a similar service delivery system to common service distribution and social welfare. Therefore, the author has assumed the efficiency of the service delivery system of social welfare to be equivalent to the service distribution industry. Hence, various kinds of social welfare services for the prevention of elderly suicide, from the perspective of distribution, are discussed. Studies on generational relations have thus far investigated depression from parent-children conflict, and satisfaction with their lives. Studies on the relationship between family solidarity and elderly suicide by analyzing existing social problems are rare. This study investigated the effects of family solidarity between old parents and adult children upon elderly suicide by analyzing serious psychological and social problems. This study revealed basic measures for elderly suicide prevention through services that could elevate family solidarity from the perspective of social welfare service distribution. Research design, data, and methodology - The subjects were 468 elderly, 65 years or older, at 18 senior welfare centers and halls for the elderly at Seoul and Gyeonggi-do. Questionnaire surveys, excluding invalid answers, were analyzed. Convenience sampling was used from February 5, 2014 to March 5, 2014. The findings were: First, women and those having spouses with advanced educational backgrounds and social activities had primary solidarity such as contact solidarity, affectionate solidarity, functional solidarity (giving help), and functional solidarity (receiving help). In addition, those who had good health, from a subjective point of view, had more solidarity. Second, the elderly who were men and single, and who had poorer educational backgrounds thought of suicide, lacked social activities, and had poor health, from a subjective point of view. Third, family solidarity between old parents and adult children had significantly negative influence on the suicidal ideation of the elderly. Results - The study revealed the following implications. First, the preparation for old age should consider not only economic welfare but also the psychological welfare due to the relationship with children. Second, the phenomenon of elderly suicide because of a lack of family solidarity could increase national loss and have great influence upon welfare in old age. Therefore, planning of welfare services for the elderly should consider the value of relationships with children to improve the psychological welfare of the elderly. Third, the social expenses of government-oriented support for parents should be discussed from the people's point of view. Conclusions - The subjects of the study comprised the elderly at Seoul and Gyenggi-do; therefore, it would be difficult to extrapolate the findings to all the elderly in the nation. The subject visited senior welfare centers as well as halls for the elderly; therefore, it would be difficult to assume that the trends were representative of the elderly in the nation.

  • The Distribution System consist of many tie-line switches and sectionalizing switches, operated a radial type. When an outage occurs in Distribution System, outage areas are isolated by system switches, has to restored as soon as possible. At this time, system operator have to get a information about network topology for service restoration of outage areas. Therefore, the searching result of restorative topology has to fast computation time and reliable result topology for to restore a electric service to outage areas, equal to optimal switching operation problem. So, the problem can be defined as combinatorial optimization problem. The service restoration problem is so important problem which have outage area minimization, outage loss minimization. Many researcher is applying to the service restoration problem with various techniques. In this paper, advanced Dijkstra algorithm is applied to searching a restoration topology, is so efficient to searching a shortest path in graph type network. Additionally, fuzzy rules and operator are applied to overcome a fuzziness of correlation with input data. The present technique has superior results which are fast computation time and searching results than previous researches, demonstrated by example distribution model system which has 3 feeders, 26 buses.

  • One of the economical ways to satisfy the quality of service desired by the user in a web service environment is to adjust the size of the object. To this end, this study finds the maximum size of objects that satisfy this constraint when the mean response time is given below an arbitrary threshold for quality of service. It can be inferred that in the steady state of system, the mean response time in the deterministic model by using the round-robin will be the same as that of the queueing model following the general distribution. Based on this, analytical formulas and procedures for finding the maximum object size are obtained. As a service distribution of web traffic, the Pareto distribution is appropriate, so the maximum object size is computed by applying the M/G(Pareto)/1 model and the M/G/1/PS model using exponential distribution as computational experience. Performance evaluation through numerical calculation shows that as the shape parameter in the Pareto distribution increases, the M/G(Pareto)/1 model and M/G/1/PS model have the same maximum object size. The results of this study can be used to environments where objects can be sized for economical web service control.

  • Storage services integration can be done for achieving high availability, improving data access performance and scalability while preventing vendor lock-in. However, multiple services environment management and interoperability have become a critical issue as a result of service architectures and communication interfaces heterogeneity. Storage federation model provides the integration of multiple heterogeneous and self-sufficient storage systems with a single control point and automated decision making about data distribution. In order to integrate diverse heterogeneous storage services into a single storage pool, we are proposing a storage service federation framework named BoxBroker. Moreover, an automated decision model based on a policy-driven data distribution algorithm and a service evaluation method is proposed enabling BoxBroker to make optimal decisions. Finally, a demonstration of our proposal capabilities is presented and discussed.

  • In this paper, we propose a task distribution scheme in fog computing environment considering opportunistic fog computing nodes. As latency is one of the important performance metric for IoT(Internet of Things) applications, there have been lots of researches on the fog computing system. However, since the load can be concentrated to the specific fog computing nodes due to the spatial and temporal IoT characteristics, the load distribution should be considered to prevent the performance degradation. Therefore, this paper proposes a task distribution scheme which considers the static as well as opportunistic fog computing nodes according to their mobility feature. Especially, based on the task requirements, the proposed scheme supports the delay sensitive task processing at the static fog node and delay in-sensitive tasks by means of the opportunistic fog nodes for the task distribution. Based on the performance evaluation, the proposed scheme shows low service response time compared to the conventional schemes.
