With the increase of the aging population in Korea, the welfare of Korean elderly has become one of main concerns of the society. One essential factor that may enhance the quality of life of the elderly is the active social participation. Involvement in the volunteer activity is one form of social participation that benefits both society and individual. The purpose of this study is to examine the level of Korean elderly's participation in volunteer activities and factors related to their participation in the context of different age group. People aged 55 and over from wave 2 data of Korean Longitudinal Study of Ageing are grouped into pre-old(55-64), young old(65-75), and old old (75 and older). Main analytic tools include descriptive statistics and logistic regression analysis. Results indicated that social relationships of the elderly were the most important factors related with their participation with voluntary activities. Also highlighted is the importance of considering the diversity among the older population.

The beauty industry relies heavier upon the specialized labor of beauty industry employees than any other industry. Beauty industry employees directly meet their clients and are required to provide services with extremely delicate care. The sense of happiness of employees working at the interface of service provision matters most importantly for beauty industry growth. In this study, the correlation among beauty industry employees' resilience, happiness index and job satisfaction was tested under hypotheses. As a result, their resilience was found to have a significant effect on happiness index and job satisfaction; happiness index, on job satisfaction and resilience; and job satisfaction, on resilience and happiness index. Consequentially, it was found that when individual happiness increased, their job satisfaction moved up along with job performance. In this sense, for the further development of beauty industry, it is deemed necessary to consider methods to improve the sense of happiness of beauty industry employees.

The main objective of this study was to identify the difference in the perceptions of the product attributes and the expected benefits for consumers and professionals in the performing arts industry. First, the Delphi method by using email and telephone was used to explore the professionals' perceptions of the attributes of performing arts and the expected benefits. Second, on-line consumer survey was used to explore the consumer perceptions of the attributes of performing arts and the expected benefits. Finally, this study tried to draw some difference of perceptions from both professionals and consumers. Contents of the arts, location of a theater, ticket price, relief of stress, and improvement of lifestyle were found to be commonly important factors for both parties. Among them, statistical differences between two groups were confirmed in the factors such as the reputations of the cast members and theatres, locations of theatres, and time duration of a performance.

The number of stepfamilies is rapidly growing in our society according to social changes. So family programs especially for stepfamily relationship enforcement with adolescents at home are needed. The purpose of this study is to investigate the direction of family programs for enforcing the stepfamily relationship between stepparents and stepchildren. For the purpose, case studies from those stepfamilies were analyzed through qualitative interviews and early developed program contens were referred. Based on discussion mentioned above, program development direction for stepfamily relationship enforcement is not only dealing with difficulties of stepfamilies in their early remarriage but also emphasizing their advantages. In conclusion, this program development direction expected stepfamilies to resolve their problems and to prevent their family break up as well as to deliver practical benefits.

Most of the existing algorithms try to disseminate the multimedia contents of internet service provider(ISP), without taking into account the needs and characteristics of specific websites including e-learning systems with web-based .educational contents. Sometimes the client must select the best one among the replicated repositories. However, this is a less reliable approach because clients' selections are made without prior information on server load capacity. In this paper we propose an agent system inspired by the need of improving QoS of delivering web-based educational multimedia contents without incurring long access delays. This agent system consists of three components, Analyzer, Knowledge Base, and Automaton embedded the capacity algorithm. It analyzes and investigates traffic information collected from individual replicated server by learners' requests, and selects a server which is available and is expected to provide the fastest latency time and the lowest loaded capacity, and achieves high performance by dynamic replicating web resources among multiple repositories.

To provide efficient and correct search results, ontology which use the structure of information, is considered as a main mechanism in the semantic web. Therefore, recent research in information retrieval and data construction have emphasized the use of ontologies as a data representation and search mechanism. In this paper, we propose a semantic search method using ontology to improve search ability in web environment. Ontology and knowledge base is used to represent semantic meaning of the data and provide related web documents and facts as results. Also, search result ranking mechanism is proposed. The mechanism use cardinality of the keyword in the contents and structural information of ontology. Experimental results with several query processing indicate that different coefficient value in the expression gives different results in sample ontology system and we propose appropriate values of the coefficient.

As mobiles devices with high-spec camera built in are used widely, the visual quality enhancement of the high-resolution images turns out to be one of the key capabilities of the mobile devices. Due to the limited computational resources of the mobile devices and the size of the high-resolution images, we should choose an image processing algorithm not too complex and use an efficient implementation technology. One of the simple and widely used image quality enhancement algorithms is contrast stretching. Java libraries running on a virtual machine, JNI (Java Native Interface) based native C/C++, and NEONTM SIMD (Single Instruction Multiple Data) are common implementation technologies in the case of Android smartphones. Using these three implementation technologies, we have implemented two image contrast stretching algorithms - linear and equalized, and compared the computation times. The native C/C++ and the NEONTM SIMD outperformed the native C/C++ implementation by 56-78 and 50-76 time faster respectively.

Due to the advances in machine learning and artificial intelligence technologies, many new services have become available. Among such services, recommendation systems have already been successfully applied to commercial services and made profits as in online shopping malls. Most recommendation algorithms in commercial services are based on content analysis or explicit feedback rates as in movie recommendations. However, many online shopping malls have difficulties in content analysis or are lacking explicit feedbacks on their items, which results in no recommendation system for their items. Even for such service systems, user log data is easily available, and if recommendations are possible with such log data, the quality of their service can be improved. In this paper, we extract implicit feedback like click information for items from log data and provide a recommendation system based on the implicit feedback. The proposed system is applied to a real in-service online shopping mall.
