Through contemporary researches on policing, individual employees in law enforcement agencies has gained more and more attention from researchers and police organization managers. Unfortunately an important but largely ignored area of current research on individual police officers concerns the value orientations obtaining among Korean police officers. And during last five decades or so, no research has been done on this issue. Studying individual value orientations is important because a substantial body of research indicates that particular patterns of value orientation predict world views and hence can in turn predict behavior at the workplace and behavioral predispositions on salient social issues. Therefore in this research, the researcher intended to answer these issues. (1) What are the characteristics of value orientations among Korean police officers. (2) Is there any relationships between the specific groups and the value orientations among them.

Das Wortspiel $hei{\ss}t$ die spielerische $Ver\"{a}nderung$ eines Wortes zum Zwecke $\"{u}berraschender$ Wirkungen, und die Werbetexter betrachten es monentan als ein beliebtes, wirkungsvolles Ausdrucksmittel $f\"{u}r$ die Werbeanzeigen. (1) Sag mal, wie war eigentlich dein erstes Mal? Und wie oft machst du es in der Woche? Und was sagt deine beste Freundin dazu? -Gesichtsreinigungsmittel Clearasil Complete(Janich, 1999:146) (2) 대장님 힘 내세요! 뒷일은 제가 책임지겠습니다. -아락실 (3) 당신은 철없는 여자. -헤모큐 Das Wortspiel $l\"{a}{\ss}t$ den Referenzbezug ausweiten, vage oder $ungew\"{o}hnlich$ werden. Dadurch werden konventionelle Referenzerwartungen der Rezipienten verletzt und unterbrochen. Wortspiele mit Homonyme, Polyseme, Wortkreuzungen, und Referenzspiele sind sehr $h\"{a}ufig$, und die syntaktische und typographische Spiele dagegen eher selten. Die Wirkung des Wortspiel beruht auf die $Ambiguit\"{a}t$ eines Wortes. Aber zwischen der$Ambiguit\"{a}t$ und der Vagheit gibt es den $un\"{u}bersehbaren$ referenziellen Unterschied. $W\'{a}hrend$ diese, die durch die pragmatische Mehrdeutigkeit oder die Unbestimmtheit charakterisiert ist, mit der in einer $\"{A}u{\ss}erung ausgedr\"{u}ckten$ Vorstellung zu tun hat, handelt es bei jener um die Probleme der linguistischen Kategorien an, die unter lexikalischem, semantischem, und syntaktischem Aspekt mehrfach zu spezifizieren sind. Daher $k\"{o}nnen$ den wortspielerischen $Ausdr\"{u}cken$ mehere Interpretationsmoglichkeiten zugeordnet werden. Durch Wortspiele wird die Eindeutigkeit eines Wortes absichtlich aufgehoben, so $da{\ss}$ mehere denotativen Bedeutungen aktiviert werden. Dabei liegt eine semantische Konzentration oder ein semantisches Spannungsverhaltnis vor, Diesbezuglich $erf\"{u}llt$ das Wortspiel zugleich die Funktion, Aufmerksamkeit des Rezipienten auf den geworbenen Inhalt zu wecken, und $f\"{o}rdert$ das Interesse am Werbetext.

This review deals briefly with the various medicinal components(mainly saikosaponins), their biological activities and the variation of their contents by different cultivation environment and plant parts in Bupleurum species. Bupleuri radix, a crude drug, is the root of Bupleurum falcatum L. (Korea, Japan), B. chinense(China), and their related species (Umbelliferae). There are over 120 species in Bupleurum genus throughout world, mainly Asian area, and over 5 species in Korea, investigated up to now. These plants contain many physiological active compounds and the principal components are saikosaponins. Major activities of this crude drug and saikosaponins are the anti-inflammatory and antihepatotoxic activities. Saikosaponins and their derivatives in Bupleurum spp. have been chemically studied, isolated and identified over 70 compounds in over 50 species. Other components, physiologically active ones, also have been investigated, which are the groups of lignan, flavonoid, essential oil, polyacetylene, polysaccharide, etc. Saikosaponins belong to the group of triterpenoid saponin chemotaxonomically and occur the accumulation and turnover in plant tissues through secondary metabolism, mevalonic acid pathway. The contents and kinds of saikosaponins and other components in Bupleurum spp. plants are various due to different species and growing environments, as the plant growth characters and yield are various. Most of medicinal plants as well as Bupleurum species are very useful as agricultural products and traditional medicines, and also are very valuable as genetic resources and natural products. So we need to collect, evaluate, preserve, and utilize various medicinal plants, and also to under-stand secondary metabolism and improve the breeding and cultivation techniques for the safe production of crude drugs with high quality and yielding.

Sand Compaction Pile and Stone Column method have been used in widely during several decades as a technique to reinforce soft soils and increasing ultimate bearing capacity, accelerate consolidation settlement of the foundation ground. Stone column method, making a compaction pile using crushed stone, is a soft ground improvement method. However, stone column method is difficult to apply to the ground which is not mobilized enough lateral confine pressure because no bulging failure resistance. Hence, in present study, development the geogrid reinforced stone column system for settlement reduction and wide range of application of stone columns. To develop this system, triaxial compression tests were conducted for evaluation which is about behavior characteristics of stone column on replacement rate and confine pressure. Then, 3-dimensional numerical analysis were evaluated for application of the GRSC (geogrid reinforced stone column) system as evaluate behavior characteristics and settlement reduction effect of stone column reinforced by geogrid on types and reinforcing depth change of geogrid.

Human placenta extract (hPE) has therapeutic potential against certain diseases such as burn injury, liver cirrhosis and chronic wound through stimulating tissue repair processes. However, the effects of hPE on liver regeneration in animals are unknown. This study investigated the effect of hPE on the expression of proliferating cell nuclear antigen (PCNA) during liver regeneration induced by partial hepatectomy (PH) in rats. The activities of AST, ALT and ALP increased during a few days after PH. A high level of ALP was particularly seen at day 3 in the control group. All the levels of experimental groups were normalized by day 5 after PH. On immunohistochemistry, the expression of PCNA increased at the early days, showed a peak at day 3 after PH. The PCNA staining was more obvious in the experimental group over the whole period. By western blotting, PCNA seemed to be more strongly expressed in the hPE injected group in the early stage and fell to almost undetectable levels at day 7. On immunocytochemical observations, the number of PCNA-gold particles in the nuclei at day 1 of the hPE treated groups was more than those of the untreated groups. The results suggest that hPE could accelerate liver regeneration induced by PH involving the expression of PCNA in rats.

Objectives: This study was conducted to investigate the effects of dental hygienists' job satisfaction on turnover intention and intention to stay. Methods: A survey was conducted targeting 273 dental hygienists in dental clinics. The study data were u analyzed using PASW Statistics 20.0 Results: The level of job satisfaction of dental hygienists was 3.30±0.50, and the highest ranked item in the survey was 'I am satisfied with my relationships with patients' 3.72±0.73. Job satisfaction according to general characteristics showed significant differences in age, marriage, education, career, current work experience, position, and schedule for future turnover. The turnover intention according to general characteristics showed significant difference in age and schedule for future turnover. The intention to stay according to general characteristics showed significant differences in age, marriage, education, career, current work experience, number of dentists, number of dental hygienists, and schedule for future turnover. The factors affecting turnover intention were schedule for future turnover, income, co-worker relation and professional time, while those affecting intention to stay were overall professional satisfaction, co-worker relation, schedule for future turnover, professional time, income, number of dental hygienists, patient relations and current work experience. Conclusions: Job satisfaction factors that had a common effect on turnover intention and intention to stay were schedule for future turnover, income, co-worker relation and professional time. To reduce turnover and encourage longevity, adequate pay and positive interpersonal relationships are necessary.

For the prediction on the onset of oblique shock wave-induced vortex breakdown, computational studies on the Oblique Shock wave/Vortex Interaction (OSVI) are conducted and compared with both experimental results and analytic mode1. A Shock-stable numerical scheme, the Roe scheme with Mach number-based function (RoeM), and a two-equation eddy viscosity-transport approach arc used for three-dimensional turbulent flow computations. The computational configuration is identical to available experiment, and we attempt to ascertain the effect of parameters such as a vortex strength, streamwise velocity deficit, and shock strength at a freestream Mach number of 2.49. Numerical simulations using the k-w SST turbulence model and suitably modeled vortex profiles are able to accurately reproduce many fine features through a direct comparison with experimental observations. The present computational approach to determine the criterion on the onset of oblique shock wave-induced vortex breakdown is found to be in good agreement with both the experimental result and the analytic prediction.

Flows in segmented arc-heaters have been calculated for prediction of experimental operating condition or for analysis and design of arc-heater itself. Some researchers succeeded in calculating accurately inner flows of a arc-heater, but could not made mathematical models which satisfy various operating conditions for many arc-heaters. this study is forced on turbulence for the generality of mathematical model. Instead of algebraic turbulence models which are frequently used for calculating inner flow of arc-heater, two equation turbulent models are used. Prediction results agree well with experiment data and it was confirmed that $k-\varepsilon$ two equation turbulence model is appropriate for a flow in an arc heater throughout extensive numerical testing.

The silicon thin film solar cells were fabricated by 13.56 MHz PECVD (Plasma-Enhanced Chemical-Vapor Deposition) and 60 MHz VHF PECVD (Very High-Frequency Plasma-Enhanced Chemical-Vapor Deposition). We focus on textured ZnO:Al films prepared by RF sputtering and post deposition wet chemical etching and studied the surface morphology and optical properties. These films were optimized the light scattering properties of the textured ZnO:Al after wet chemical etching. Finally, the textured ZnO:Al films were successfully applied as substrates for silicon thin films solar cells. The efficiency of tandem solar cells with $0.25 cm^2$ area was $11.8\%$ under $100mW/cm^2$ light intensity. The electrical properties of tandem solar cells were measured with solar simulator (AM 1.5, $100 mW/cm^2)$ and spectral response measurements.
