Korean is exposed to a rapid growth in economy and considerable amount of time for leisure. There is no doubt that the leisure industry is playing a significant role in making our lives enjoyable and therefore leading a quality lift. In a range of research. it has been shown that the essence of leisure functions properly where the degree of leisure satisfaction is high. Thus, this study attempts to identify the cognition of leisure by undergraduate students in Kyongju University and to suggest alternative solutions for then. The research findings and their implications are summarized as follows. Firstly, a large percentage of the students take a serious view of work and leisure. Secondly, the satisfiers of own leisure activity are rather than dissatisfied students, because they regard their leisure activities as reasonableness and soundness. Lastly, students consider leisure as their mental state of comformt and pleasure. The results implies that systematic and in-depth education on the leisure and enrichment of leisure facilities are required in order to become higher students' satisfaction of own leisure activities.

본 연구의 목적은 사회복지조직의 공개 채용공고가 실제채용기준을 얼마나 반영하고 있는지 파악하여 채용공고의 변화가능성을 탐색하기 위함이다. 이러한 목적을 달성하기 위해 2008년 한국사회복지사협회의 채용공고 중 210건의 조직을 표집하여 기초분석을 통해 정보내용을 파악하였고, 서울과 대전의 23개 조직의 기관장을 대상으로 1:1면접을 통해 사례연구를 진행하였다. 분석결과, 실제채용기준은 자원봉사와 실습을 통한 현장경험, 사회복지사 1급 자격증, 지원자와 조직의 비전 일치, 사회복지 마인드, 대인관계 등으로 드러났다. 그러나 이는 채용공고에 제시되지 않거나 질적인 차이를 보였다. The purpose of this study is to understand how an open employment notice has reflected the actual criterions of the recruitment, and to discover a potential for any changes. To achieve this purpose, a systematic random sample of 210 open employment notices was selected from Korea Association of Social Workers in 2008, and a descriptive analysis was conducted. The qualitative research was carried out for the case study with 23 interviewees from social welfare organizations in Seoul and Daejeon. Consequently, the actual criterions of the recruitment included the following elements: social work field practicum and volunteer work, the level one social welfare license, degree of harmony with the vision of the organization, dept of social welfare-oriented mind, and human networks. However, these criterions may not be presented in open employment notices or show that there are qualitative differences between open employment notices and the actual employment criterions.

A neural network approach has been developed to determine the depth of a surface breaking crack in a steel plate from ultrasonic backscattering data. The network is trained by the use of feedforward three-layered network together with a back-scattering algorithm for error correction. The signal used for crack insonification is a mode converted 70˚ transverse wave. A numerical analysis of back scattered field is carried out based on elastic wave theory, by the use of the boundary element method. The numerical data are calibrated by comparison with experimental data. The numerical analysis provides synthetic data for the training of the network. The training data have been calculated for cracks with specified increments of the crack depth. The performance of the network has been tested on other synthetic data and experimental data which are different form the training data.

( You Young Jo ),( Hee Jung Lee ),( Ui Lyong Lee ),( Byoung Moo Seo ),( Pill Hoon Choung ) 한국조직공학과 재생의학회 2006 조직공학과 재생의학 Vol.3 No.4

To investigate effect of platelet-rich plasma(PRP) on proliferation and differentiation of postnatal stem cells derived from human dental tissues, we isolated stem cells from dental tissues such as dental pulp, periodontal ligament, and surrounding mandibular bone. The isolated dental stem cells were tested on colony forming ability, proliferation, and ALP activity at different concentration of PRP. All of dental stem cells showed high proliferation as increased concentration of PRP. On the contrary, high concentration PRP such as 5% inhibited proliferation of stem cells. These results suggest that the proper concentration of PRP can be utilized to accelerate the proliferation of human dental stem cells.

<P>A proto-type hybrid electro-magnetic suspension system (hybrid EMS system) was developed by Yonsei university . It is the first step of study on fundamental technology for advanced railroad system development. The proto-type hybrid EMS system consists of a ferromagnetic-core, a superconducting magnet (Bi-2223) for generating magneto-motive force (MMF) and a control coil for levitation control. This system has the characteristic of a control coil generating a magnetic flux to keep the levitation gap in constant value when the gap is attempted to be varied by external physical factors. In doing so, the induced current by the magnetic flux generate loss to the superconducting magnet inducing the possibility of an unstable system. Therefore, we have experimented and documented the results of evaluating the loss in the superconducting magnet generated by the control coil. This paper can be expected to suggest useful data for the design and operation of a hybrid EMS system.</P>
