The purpose of this study was to examine the differences of the satisfaction level and physical self efficiency for female students in high school as a function of the styles of P. E. class, specialized P. E. class and generalized P. E. class. The questionnaire used in this research consisted of 15 items for satisfaction and 17 items for physical self efficiency, based on those of D. Park(2005) and E. Chung's(2005) alternatively. Total 334 data (163 for specialized P. E. class & 171 for generalized P. E. class) were analyzed by using MANOVA. Results revealed that the specialized P. E. class showed higher satisfaction level and greater physical self efficiency than the generalized P. E. class. These suggest that the specialized P. E. class may be one of alternative methods for raising the satisfaction of P. E. class and for enhancing the physical self efficiency through P. E. class in current physical educational environment.

Bridgman법에 의한 CdIn₂Te₄ 단결정 성장과 defect 연구

하종호,홍명석,홍광준 조선대학교 에너지.자원신기술연구소 2003 에너지·자원신기술연구소 논문지 Vol.25 No.2

수평 전기로에서 CdIn₂Te₄ 다결정을 합성하여 Bridgeman 법으로 3단 수직 전기로에서 CdIn₂Te₄ 단결정을 성장하였다. 성장된 결정의 특성은 x선 회절과 광발광 측정으로 조사하였다. CdIn₂Te₄ 단결정 시료는 Laue에 배면 반사법에 의해서 (001)면으로 성장되었음을 확인하였다. Hall 효과는 van der Pauw 방법에 의해 측정되었으며, 온도에 의존하는 운반자 농도와 이동도는 293K에서 각각 8.61×10^(16) /㎤, 242 cm²/V·s였다. CdIn₂Te₄ 단결정의 광흡수와 광전류 spectra를 293K에서 10K까지 측정하였다. 광흡수 스펙트럼으로부터 band gap E_(g)(T)는 Varshni 공식에 따라 계산한 결과 1.4750eV-(7.69×10^(-3) eV/K)T²/(T+2147 K)임을 확인하였다. 막 성장된(as-grown) CdIn₂Te₄ 단결정 시료를 Cd-, In-, Te 분위기에서 열처리하여 10K에서 photolumine science(PL) spectra를 측정하여 점 결함의 기원을 알아보았다. CdIn₂Te₄ 단결정내에서 내재된 결함들의 기원을 10 K에서 광발광을 측정하여 연구되었다. PL 측정으로부터 얻어진 V_(Te), Cd_(int), 그리고 V_(Cd) Te_(int)는 주개와 받개로 분류되어졌다. CdIn₂Te₄ 단결정 시료를 Cd 분위기에서 열처리하면 n형으로 변환됨을 알 수 있었고, In 분위기에서 열처리하면 열처리 이전의 PL spectra를 보이고 있어서 I₂, I₁ 및 S.A emission에 의한 PL peak에는 영향을 주지 않는다고 보았다. A stoichiometric mixture for CdIn₂Te₄ single crystal was prepared from horizontal electric furnace. The CdIn₂Te₄ single crystal was grown in the three-stage vertical electric furnace by using Bridgman method. The quality of the grown crystal has been investigated by the x-ray diffraction and the photoluminescence measurements. The (001) growth plane of oriented CdIn₂Te₄ single crystal was confirmed from back-reflection Laue patterns. The carrier density and mobility of CdIn₂Te₄ single crystal measured with Hall effect by van der Pauw method are 8.61×10^(16) ㎤ and 242 ㎠/V·s at 293K, respectively. The temperature dependence of the energy band gap of the CdIn₂Te₄ single crystal obtained from the absorption spectra was well described by the Varshni's relation, E_(g)(T) = 1.4750 eV - (7.69× 10^(-3) eV)T²/(T+ 2147). After the as-grown CdIn₂Te₄ single crystal was annealed in Cd-, In-, and Te-atmospheres, the origin of point defects of CdIn₂Te₄ single crystal has been investigated by the photoluminescence(PL) at 10 K. The native defects of V_(Te), Cd_(int), and V_(Cd), Te_(int) obtained by PL measurements were classified as a donors or acceptors type. And we concluded that the heat-treatment in the Cd-atmosphere converted CdIn₂Te₄ single crystal to an optical n-type. Also, we confirmed that In in CdIn₂Te₄ did not form the native defects because In in CdIn₂Te₄ single crystal existed in the form of stable bonds.

人間의 c-Ha-ras發癌性 蛋白質에 結合되어 있는 GDP와 GTP의 形態 比較

河鍾明 新羅大學校 1991 論文集 Vol.31 No.1

A truncated human c-Ha-ras gene product 〔ras(1-17)protein〕in which glutamine-61 was replaced by leucine 〔ras(L61/1-171)protein〕, was prepared and ligand was exchanged from GDP to GTPγS 〔Guanosine 5'(3-0-thio) triphosphate〕. A mass production of ras protein bound with GTPγS was possible using ultra-filtration with chealating agent. GTPγS bound to c-Ha-ras protein was clearly confirmed by ultra-violet spectroscopy and phosphorus nuclear magnetic resonance. The conformations of a bound GDP and a bound GTP to a ras(L61/1-171)protein were compared by time dependent nuclear Overhauser effect (NOE) spectroscopy. The dependences of the H1' and H8 proton resonance intensities on duration of time-dependent NOE profiles, and the conformation of the protein-bound GDP and GTPγS were elu??dated ; as for the bound GDP, the guanosine moiety takes the antiform about N-glycosidic bond with the dihedral angle of χ=-124±2° and the riose ring takes the C2'-endo form(Ha. 1990). Whereas the bound GTPγS, the guanosine moiety, takes the anti form about N-glycosidic bond with the dihedral angle of χ=-80±2°and the ribose ring takes the C3'-endo form The conformations around effector region are of the regular structure in the GDP-bound state, and largely distorted in the GTPγS-bound state, whichis probably related to the conformational activation of the effector region of ras proteins by ligand substitution of GDP with GTPγS. The role of the interaction between the bound guanine nucleotide and effector region is discussed with regard to the mechanism of the ras protein functions.

하동욱,강명근,박종,김율 朝鮮大學校 附設 醫學硏究所 2007 The Medical Journal of Chosun University Vol.32 No.3

Background: Regarding non-medical services of hospitals, most of them have concerned and have made an efforts to managed it. But there were only a few studies on how it influenced on customers' loyalty, comparing to medical services. Purpose: Then, this study was conducted to identify the influence of satisfaction with non-medical services on customers' loyalty towards hospitals. Methods: The study subjects were 229 inpatients of a university hospital. The data were collected by a structured questionnaire from them. Results: As the results of hierarchical multiple regression analysis, adjusting with general characteristics and satisfaction with medical service, the explanatory power of satisfaction with non-medical services on overall customers' loyalty was 2.2%, which was statistically significant in borderline. But the value was very lower than that of satisfaction with medical services, Conclusions: In order to keep up with high level of customers' loyalty towards hospitals, it might be necessary to manage quality of medical service area primarily, but the importance of non-medical service areas should not be neglected because they might have a little but 'significant' influencing power.

집단 따돌림 현상에 나타난 청년 초기의 의복 행동

河希貞,韓明淑 服飾文化學會 2000 服飾文化硏究 Vol.8 No.2

In this study, we inquire what is the rules which is implicitly used by the adolescent group about bullying phenomenon. We inquire how to interpret the phenomenon from the adolesents' viewpoint and their opinions of how appearance and clothing determine the extent of bullying. After we discuss this problem, we propose an indirect solution to the cause of bullying. We selected a middle school boy by reason that boys have been more experienced than others according to a previous study and are at a keen adolescent stage of development. Moreover, "ichime" phenomenon is seriously reported at a middle school student stage in the case of Japan. The purpose of the study was to analyze the following : 1. Research on an actual case of bullying in a middle school student. 2. the adolescents' viewpoint on characteristics of school bullying. 3. The cause of violence and injry from school bullying. 4. How appearance and clothing affect bullying. 5. The preference and uses of clothing worn by adolescents. The process of this study brought a substantially between quantitative and qualitative research. These questionnaires were administered to 320 middle school students in Seoul from the 14th to the 25th of June. The data totaled up to 280 subjects, which consist of 121 male students and 159 female students except for invalid data.

해운선사의 효율성 및 생산함수 특성 분석 : The Case of Shipping Companies

하영석,이명헌 한국해운물류학회 2004 해운물류연구 Vol.43 No.-

비용최소화를 전제하지 많은 暗默비용함수를 추정하여 국내 28개 외항 해운업체를 대상으로 분배 효율성 분석을 실시하였다. 투입요소간 한계기술대체율과 시장가격의 비율이 일치하여 최소의 비용으로 생산이 이루어지고 있음을 뜻하는 상대가격 효율성은 기각되었다. 세부적으로 두 요소간 효율적 분배 여부를 검증한 결과 가변재-노동만 채택되고 자본-노동, 자본-가변재는 기각되었다. 요소간 비효율적 분배로 인하여 생산비용이 평균 2% 증가한 것으로 나타났는데, 자본과 가변재는 각각 적정 수준보다 평균 9.4%와 9.2% 만큼 적게 투입된 반면 노동은 13.3% 만큼 필요 이상으로 사용되었다. 결국 2%의 생산비 상승이 초래된 이유는 자본과 가변재의 과소 투입으로 발생한 생산비 감소분을 능가하는 노동의 과잉 투입이 있었기 때문이다. 생산함수의 동조성, 동차성 모두 기각되었다. 규모의 경제는 평균 42.5%로 추정되었으며 산출량 규모와 규모의 경제는 비례하지 많음을 발견하였다. 자본-노동은 보완적 관계로, 자본-가변재, 노동-가변재는 대체 관계로 나타났다. We test for allocative efficiency of inputs with data for 28 firms in the Korean shipping industry utilizing the `shadow' cost function. The hypothesis that firms do minimize costs subject to market prices is rejected. The attainment of allocative efficiency between variable input and labor is accepted, while capital-labor and capital-variable input are rejected. Allocative inefficiency causes an increase in total cost by 2 percent, on average. Allocative distortion, on average, reduces the demand for capital and variable input by 9.4 percent and 9.2 percent; while the demand for labor is increased by 13.3 percent. Homotheticity of the production function is rejected. The average estimate of scale economies is 42.5 percent. The estimates of the elasticites of substitution indicate that capital and labor are complements; while capital and labor are both substitutable with variable input.

Heligmosomoides polygyrus 감염 마우스의 비장세포로 부터 만든 Conditioned Supernatant의 면역억제작용

하대유,한병갑,김명선,고유승 大韓免疫學會 1996 大韓免疫學會誌 Vol.18 No.3

Heligmosomoides polygyrus is gastrointestinal parasitic nematoda which is common parasire of wild rodents. The experimental infection with this parasite has been studied extensively in models of host-parasite interaction. The present study was undertaken to investigate both the effects of administration of conditioned supernatant or conditioned medium(CM) prepared from H. polygyrus-infected mice on the humoral and cellular immune responses in mice. Normal conditioned supernatant(NCM) was prepared from uninfected mouse splenocytes stimulated with Con A. Supematants conditioned by Con A-stimulated splenocytes of H. polygyrus -infected mice were prepared on different days post-infection, namely on day 6(HCM-D6), day 14 (HCMD14) and day 18 (HCM-D18) post-infection with H. polygyrus L3 larvae. Effects of NCM, HCM-D6, HCM-D14 and HCM-D18 on delayed-type hypersensitivity(DTH) to sheep red blood cells (SRBC), contact hypersensitivity to dinitrofluorobenzene (DNFB), hemagglutinin response to SRBC, ovalbumin (OVA)-induced active systemic anaphylaxis(ASA), and anti-OVA specific IgE were investigated. Effect of anti-IL-4 antibody (11B11) on immunoinhibitory action of HCMD18 in OVA-induced ASA was also investigated. It was found that the administration into mice of HCM-D6, HCM-D14 or HCM-D18 significantly suppressed DTH to SRBC, contact hypersensitivity to DNFB, hemagglutinin response compared with NCM. The degree of immunosuppressive activity of HCM was less marked in HCM-D6 than HCM-D14 and HCM-D18. Interestingly, HCM-D18 prepared from ICR mouse strain also showed the profound suppression of OVA-induced ASA in BALB/c and C57BL/6 mouse strains as well as in ICR mice. ASA-inhibitory activity of HCM-D18 was Somewhat abrogated in terms of mouse mortality when mice were treated in the combination of HCM-D18 and anti-IL-4 antibody, indicating that IL-4 may play a role, at least in part, in the inhibitory activity of HCM. Taken together, the present study may be the first to demonstrate that conditioned supernatants prepared from the spleen cells of H. polygyrus-infected mice may suppress the in vivo humoral and cellular immyne responses to heterologous antigens, particularly fatal anaphylaxis induced by OVA, strongly suggesting that

요셉 로트의 하르츠롸 뤼겐섬 기행에 나타난 시대성찰

하명해 한국독어독문학회 1995 獨逸文學 Vol.58 No.1

Der Literaturkritiker Jens Jessen stellte vor einiger Zeit mit Recht fest, daß Joseph Roth als ,,patriotischer Sa¨nger und nostalgischer Verkla¨rer der Doppelmonarchie$quot; mißverstanden wurde, der sich aus Verzweiflung u¨ber die Zeitla¨ufte in einen weltfremden Reaktiona¨r verwandelt ha¨tte und vor der Barbarei des Nationalsozialismus in die Beschwo¨tung des o¨sterreichischen Vielvo¨lkerstaates gefiohen sei. Diesem Mißversta¨ndnis setzt sich Jessen entgegen, indem er den Blick auf den frahen Antifaschismus Roths richtet, auf die Schilderung von faschistischen Umtrieben im ersten Zeitungsroman. Das Abstempeln eines solch weitsichtigen Schriftstellers zum eltfremde(n) Tra¨umer$quot; wird auch mit dem Hinweis auf Roths unbartnherzige Angriffe in der Exilpresse gegen Nazi-Deutschland dementiert. Joseph Roth ist kein ,,weltfremder Tra¨umer$quot;, der die Utopie des Vielvo¨lkerstaates mit der historischen politischen Realita¨t verwechselte, sondern ein ,,Tra¨umer$quot; wie ein Kind, das voller Trotz die Welt der Erwachsenen durchschaut, mit Kalku¨l tra¨umt und sich zu Recht widersetzt. Die vorliegende Arbeit setzt rich zum Ziel, durch eine textnahe Lesart der Deutschland-Reisefeuilletons Roths den politischen Schriftsteller zu wu¨rdigen. Wenn das Reisen eigentlich ahrnehmungsform der Fremde$quot; oder ,,Fremderfahrung$quot; ist, bedeutet das Reisen durch Deutschland fu¨r Roth eine Erfahrung mit dem Fremdgewordenen. Das Reisen ist dabei ein Medium der Beobachtung und Wahmehmung der sich vera¨ndemden Welt, die rich von dem Herko¨mmlichen, Vertrauten entfremdet. Die vielfa¨ltigen Entfremdungserfahrungen im Zuge der Industrialisierungsprozesse, der Versta¨dterung und Natunerwahrlosung Bowie die wachsende Inhumanisierung Deutschlands in der Weimarer Republik bilden den stofflichen und thematischen Inhalt von Roths Deutschland-Reiseberichten. Was er u¨ber seine Reiseerfahmngen mitteilt, sind nicht die Vorfa¨lle. sondem die .,Symptome der Zeit und Ortes$quot;, die vom ,,Chronisten$quot;, der das Gesicht der Zeit zeichnet, aufgezeichnet werden. Roths Berichte sind von einem diagnostischen Interesse gesteuert. Roth beobachtet also symptomatologisch und beschreibt diagnostizierend. Durch seine Warnung vor der to¨dlichen Gefahr des aufziehenden Totalitarismus in Italien und Deutschland und durch seine heftige Kritik an der politischen und geistigen Situation Deutschlands und der europa¨ischen La¨nder erweist sich Roth nicht als ,.weltfremder Tra¨umer$quot; sondem als ein politisch stark engagierter Schriftsteller.

하명화,이덕희 대한산업의학회 2000 대한직업환경의학회지 Vol.12 No.2

Objectives : We evaluated demographic, socioeconomic, smoking-related, other health behavior, and disease factors associated with smoking cessation. Methods : This study included 5,493 male employees in a steel manufacturing industry, who smoked at health examination underwent in 1998. Quitters were defined as those who had stopped smoking at least one month prior to re-examination in 1999. The information on related factors was collected by self-administered questionnare. Results : At 12 months of follow-up, 1,955 patients (35.6 %) had quit smoking. The quit rate was higher in middle-aged, white collar, and high rank personnels. The quit rate increased with decreasing amount of cigarette, decreasing duration of smoking, and increasing age of starting smoking. There were higher quit rates among smokers who drank less or exercise. However, the existence of disease did not affect the quit rate. Conclusion : This study showed that many demographic, socioeconomic, smoking-related and other health behaviors associated with smoking cessation. These results could be of use in the other worksite smoking cessation campaigns to enhance the quit rate.
