The purpose of this research is to provide guiding alternatives of sound leasure activities by breaking with terms for types and behaves of its in university student's daily life. For these me, students who took class on 「Theory of leisure, has been studied concepts of leasure spontaneously as a observer, and then they has been submitted to diary-style life record table which are done activities of one week. By doing practice on diary analysis method on basis of one's life record, which are analyzed student s life and act for one week by emphasis upon leasure time. And also to increase reliance on research results, by presenting in class examples of 10 persons among main interview group, whether are unified with their opinions. The results has been shown that portion of leasure activities has various value at range of 15.7~38.0 percentage on total activities time. Most examples have presented that students have been spent leasure time efficiently, after they have examined with leasure time and made life record by themselves.

사방격자를 이용해서 물체의 형상을 측정할 수 있는 방법을 제안하였다. 카메라와 광원의 위치좌표는 변화시키지 않고 사방격자의 피치 간격을 일정한 비율로 변화시키는 방법과, 사방격자의 피치간격은 변화시키지 않고 광원과 카메라 사이의 평면 위치좌표를 변화시켜서 주기적인 무아레 무늬를 얻었으며 이를 이용하여 무아레 무늬의 절대차수를 결정할 수 있는 새로운 방법을 제안하였다. We present a simple method of determining the absolute order using periodic moire fringe structures formed by criss-crossed gratings. We selected two experimental methods that one is fixed the position coordinates of light sources and camera, and than change the pitch distance of criss-crossed gratings. Another method are fixed the pitch distance of criss-crossed gratings and than change the position coordinates of light sources and camera. As a results. We could determined the absolute order only once a photographing the objects.

대학생의 여가 인식에 관한 연구 : 경주대학교 재학생을 대상으로 focused on KYONGJU University student

조현호,유영준 경주대학교 2000 論文集 Vol.13 No.-

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.

<P>The aim of this study was to evaluate the in vivo bone regeneration capability of alginate (AL), AL/hydroxyapatite (HA), and AL/HA/silk fibroin (SF) composites. Forty Sprague Dawley rats were used for the animal experiments. Central calvarial bone (diameter: 8.0 mm) defects were grafted with AL, AL/HA, or AL/HA/SF. New bone formation was evaluated by histomorphometric analysis. To demonstrate the immunocompatibility of each group, the level of tumor necrosis factor (TNF)-α expression was studied by immunohistochemistry (IHC) and quantitative reverse transcription polymerase chain reaction (qRT-PCR) at eight weeks post implantation. Additionally, osteogenic markers, such as fibroblast growth factor (FGF)-23, osteoprotegerin (OPG), and Runt-related transcription factor (Runx2) were evaluated by qPCR or IHC at eight weeks post implantation. The AL/HA/SF group showed significantly higher new bone formation than did the control group (<I>p</I> = 0.044) and the AL group (<I>p</I> = 0.035) at four weeks post implantation. Additionally, the AL/HA/SF group showed lower relative TNF-α mRNA levels and higher FGF-23 mRNA levels than the other groups did at eight weeks post implantation. IHC results demonstrated that the AL/HA/SF group had lower TNF-α expression and higher OPG and Runx2 expression at eight weeks post implantation. Additionally, no evidence of the inflammatory reaction or giant cell formation was observed around the residual graft material. We concluded that the AL/HA/SF composite could be effective as a scaffold for bone tissue engineering.</P>

Postbiotics are heathy metabolic products in the cell-free supernatants of probiotics such as short chain fatty acids, amino acids, peptides, vitamins, etc. To enhance the stability and consumer preference, a model postbiotics, the L. casei supernatants (LS) were encapsulated in a mixed gel matrix with locust bean gum (LBG), and chicory fiber (CF). At neutral pH, a DDW/LBG/CF mixture produced a more elastic gel than a LS/LBG/CF mixture, and CF rarely affected the viscoelasticity of the gel even when 10% w/v was added. At acidic pH, when adding LBG to 2% and CF to 10%, the DDW/LBG/CF mixture did not form a gel. On the other hand, the LS/LBG/CF mixture formed a gel well at the same LBG/CF concentrations, and storage and loss moduli increased as the amount of CF was increased. As a result of the frequency sweep test, the DDW/LBG/CF mixture showed fluid-like behavior at all tested frequencies (0.1-10 Hz), and the LS/LBG/CF mixture showed typical weak gel-like behavior. This study can be usefully applied to the development of functional jelly using postbiotics in the food industry.
