The purpose of this study is to improve the reemployment rate of unemployed job seekers aged 50 to 59 by supporting the foundation of our society and enhancing their value of life. We analyzed the impact of resilience, a psychological factor, on job seeking of unemployed people in their fifties. Subjects were visited and provided employment services in the Employment Welfare Plus Center in the Seoul Metropolitan Area. We devised a questionnaire consisting of three variables of general characteristics, resilience, and job search. Also, the resilience variables comprised sub-variables of control, positiveness, and sociality, and the job search variables involved sub-variables of job preparation, attitude, and willness. Study results the resilience of unemployed persons aged 50 to 59 is above average, and sub-variables of positiveness are highest compared to other sub-variables. Second, there is no significant gender difference in resilience for job search activities. Third, resilience and its sub-variables, such as control and affirmation, affect job-seeking activities. Therefore, this study suggests strengthening the resilience of job seekers in their fifties as well as providing psychological counseling and job training for job-seeking activities.

A spatial data warehouse is a system that stores geographical information as a subject oriented, integrated, time-variant, non-volatile collection for efficiently supporting decision. This system consists of a builder and a spatial data warehouse server. A spatial data warehouse server suspends user services, stores transferred data in the data repository and constructs index using stored data for short response time. Existing methods that construct index are bulk-insertion and index transfer methods. The Bulk-insertion method has high clustering cost for constructing index and searching cost. The Index transfer method has improper for the index reconstruction method of a spatial data warehouse where periodic source data are inserted. In this paper, the efficient index reconstruction method using a partial index in a spatial data warehouse is proposed. This method is an efficient reconstruction method that transfers a partial index and stores a partial index with expecting physical location. This method clusters a spatial data making it suitable to construct index and change treated clusters to a partial index and transfers pages that store a partial index. A spatial data warehouse server reserves sequent physical space of a disk and stores a partial index in the reserved space. Through inserting a partial index into constructed index in a spatial data warehouse server, searching, splitting, remodifing costs are reduced to the minimum.

The employment prospects of graduates in the Library and Information academic has largely concentrated in the field of librarianship as well as the curriculum of the academic itself. Since there are limitations in increasing the number of libraries and the available posts in the librarianship, the full-time jobs in the field are also limited. Even for the available posts in the field of librarianship, the majority is in contract based posts which does not guarantee a good working environment. The purpose of this research is to make policy implications to improve the employment rates of librarians. The main research methods include literature review of the previous studies and available statistical data, and a questionnaire targeting students and librarians. The targeting policy implications can be categorized into 4 factors, including, as supply side, improvements in the qualification of librarian certificate, in training for librarians, and as demand side, laws on library employment, and improvement of library services for co-operatives. There are 15 detailed strategies to support the 4 factors. For the improvement of strategies in library related laws, the following elements will be considered; supporting system for temporary jobs, the title of librarian post and the library itself, and librarian placement criteria in terms of its realization and mandatory, and obligations in library evaluation. The Council discussions propose the expansion of librarian award system, provision of information systems for librarian jobs, and developments in promotional materials and their deployment for librarians.

Commonly to design a database system. a conceptual database has to be designed and then it is transformed into a logical database schema prior to building a target database system. This paper proposes a method which transforms a Temporal Entity-Relationship Model(TERM) into a Temporal Object-Oriented Model(TOOM) to build an efficient database schema. I formalize the time concept in view of object versioning and specify the constraints required during transformation procedure. The proposed transformation method contributes to getting the logical temporal data from the conceptual temporal events Without any loss of semantics, Compared to other approaches of supporting various properties, this approach is more general and efficient because it is the semantically seamless transformation method by using the orthogonality of types of objects, semantics of relationships and constraints over roles.

In case that group communication protocols assume every process is interested in all events occurring in a large scale group, the events multicasting to a subset of a large process group, such as a sensor network, potentially varying for every event based on their interests might lead to very high communication overhead on each individual process. Moreover, despite the importance of both guaranteeing message delivery order and supporting overlapped group using gossip based group communication for multicasting in sensor or P2P networks, there exist little research works on development of gossip-based protocols to satisfy all these requirements. In this paper, we present a new gossip-based causal message order guaranteeing multicast protocol based on local views and delegates representing subgroups and fully utilizing multi-group features to improve scalability. In the proposed protocol, the message delivery order in overlapped groups has been guaranteed consistently by all corresponding members of the groups including delegates. Therefore, these features of the proposed protocol might be significantly scalable rather than those of the protocols guaranteeing atomic order dependencies between multicast messages by hierarchical membership list of dedicated groups like traditional committee protocols and much stronger rather than fully decentralized protocols guaranteeing dependencies between multicast messages based on only local views. And the proposed protocol is a hybrid approach improving the inherent scalability of multicast nature by gossip-based technique in all communications.

The purpose of this study is to suggest the revision direction of the Korean Child Welfare Law based on the results of the comparative analysis on the Korean Child Welfare Law and the Japanese Child Welfare Law. The main results are: Both laws have only two provisions about children's participation right. The child protective system in Japan secures the swiftness of within-two-months period of temporary protection through the child consulting center, the investigation right by the child welfare worker, publicity, enforcement on the parents' rights, and the network with the nearest child supporting center. Furthermore, those provisions with the notifying obligation by a finder of the child who needs protection and the limit of protection period are guaranteed in order to ensure the effectiveness of law enforcement. However, Korean child protective system functions only as pre-substitutive service. While the provisions for the disability children account for 21.2% of the total Japanese law, there is no provision on that in the Korean law. The Japanese law is substantially different from the Korean law in a sense that it obligates the minimum quality criteria of child service and national financial burden on the child welfare. While the Japanese law clearly stipulates the national responsibility in relation to the degree of the rights, the Korean law does not directly touch upon it. Furthermore, the Japan's law guarantees that not only children but also protectors retain the right to choose and apply for services.

The purpose of this study is to find out perception types of service practitioners working for intellectually disabled adults on the relationships with their service users who use residential and domiciliary care services. For this purpose, this study adopted two research methods: Q-methodology and survey. This study found out three major types of practitioners' perception on the relationships with their service users. The first is the type of superficial orientation for equal relationship. The second is the type of reflective recognition on the driven relationships by practitioners. The third is that of compassionate at the advocacy for service users. In the result of survey in which respondents are practitioners working in residential care homes, small group homes and community service centers, 48.2% of respondents show the first type, 40.5% the second, 11.1% the third. Recently, in the area of personal social service for the intellectually disabled people, the importance of service users' participation and self-determination in the process of service provision is gaining higher concerns. In this context, making change on relationships between service workers and users is raised as important issue. In this environment, the results of this study could be useful to develop equal and supporting relationships.

The concept of Eco-welfare emerged in the process of discovering the relationship between a healthy ecosystem and human wellbeing. The objective of this study is to offer basic data for eco-welfare policy realization by conceptualizing the 'National Park Eco-welfare' since national parks are appropriate places for eco-welfare to be optimally implemented. A pre-workshop and two rounds of Delphi surveys were conducted to determine the concept of the 'National Park Eco-welfare ' and the main elements to be included in ecosystem service. Through this study, the concept of 'National Park Eco-welfare' was defined as efforts to conserve the biodiversity and sustainability of the ecosystem and create harmony between 'National Park Ecosystem Welfare' and 'National Park Human Welfare'. To establish the direction of the National Park Eco-welfare policy, we identified the main elements of ecosystem services which are appropriate for the National Park. These are comprised of 3 elements (food, fresh water and genetic resources) from supply service, all elements from regulating service and supporting/habitat service and 4 elements (aesthetic information, recreation-based ecotourism, healing, and knowledge systems with educational values) from culture service. In this study, the concept of National Park Eco-welfare was established, and its policy objectives and scope were suggested. However, further studies are necessary to develop action plans areand thereby realize the policy.

Thus in order to have a better understanding about the KSA(Korean Security association) and to express opinions on its role and security, this paper introduces and discusses about All Japan Security Service Association(AJSSA), which is the prototype of the KSA. There are several positive aspects to consider the introduction of, when these two associations are compared: the traffic security, a supporting member, ex-high-ranking police executive directors practically run AJSSA. These are to enhance financial ability and to promote better relationship with police. KSA needs to improve such relationship and to diversify activities as well. In addition, not just dismissing their duty by giving them the license, AJSSA provides several educations to revitalize the related people so that they can deal in effective and productive services. In another words, JSA perceives it is indispensable to educate the relevant people in the business. In contrast, it is reality that KSA has not put much emphasis on educations. Concisely, the most prompt issue is it should be more beneficial to its members by strengthening itself. Not simply following the example of foreign cases, but putting diverse efforts, KSA can make it substantial and stabilize future private security market in a long term.

Convergence is increasingly prevalent in the IT world which generally refers to the combination of two or more different technologies in a single device. Especially, the spectrum scarcity is becoming a big issue because there are exponential growth of broadcasting and communication systems in the spectrum demand. Cognitive radio (CR) is a convergence technology that is envisaged to solve the problems in wireless networks resulting from the limited available spectrum and the inefficiency in the spectrum usage by exploiting the existing wireless spectrum opportunistically. However, the very process of convergence is likely to expose significant security issues due to the merging of what have been separate services and technologies and also as a result of the introduction of new technologies. The main purpose of this research is focused on devising an adaptive security framework based on carousel for CR networks as a distinct telecommunication convergence application, which are still at the stage of being developed and standardized with the lack of security concerns. The framework uses a secure credential, named as carousel, initialized with the location related information from objects position, which is used to design security mechanisms for supporting privacy and various securities based on it. The proposed adaptive security framework could be used as a security building block for the CR network standards and various convergence applications.
