The purpose of this study was to investigate the kinematical analysis on the running motion of elementary students. The subject of this study was 12 healthy elementary students. A scholastic year were divided into 2 group : high group[6 grade], middle group[3 grade]. The following findings are obtained: It's appear that time ratio of the stance and swing in running motion about high group was 56% vs 44%, and this result was effected to wide step and stride length. Also, it's appear that displacement of center of gravity about high group was larger than middle group, and this result was effected to the horizontal velocity of center of gravity. Trunk angle was slanted to the running direction and upper arm rotation in shoulder angle was larger than middle group. And then this result was effected to the lower extremity movement. It's appear that time ratio of the stance and swing in running motion about middle group was 61% vs 39%, and this result was positively effected to narrow step and stride length. Also, it's appear that displacement of center of gravity about middle group was less than high group, and this result was effected to the low horizontal velocity of center of gravity. Trunk angle was slanted to the running direction and upper arm rotation in shoulder angle was less than high group. And then this result was negatively effected to the lower extremity movement.

본 연구의 목적은 바람직한 가정학의 정의를 내리기 위한 것이다. 먼저 정의의 논리학적인 진술 형식에 관해서 알아보고, 진술형식들을 도식화하여 이 형식에 따른 정의를 내릴 때의 준수 사항들을 제시하였다. 다음으로 선행 학자들이 내린 정의들이 거의 설명적 진술 형식을 취하고 있으므로 이 두 진술 양식을 비교해 보고, 앞으로의 가정학의 발전을 위해 그 정의에 관한 문제들을 제시하였다. 마지막으로 두 가지 정의의 진술 형식을 바탕으로 한 새로운 가정학의 정의를 내려보았다. The purpose of this paper is to make a desirable definition of home economics, For this purpose, the study has surveyed the two modes of statement about the definition of home economics: explanatory and logical. The literary survey has shown that most preceding scholars of home economics used the mode of explanatory statement in defining home economics. So it has diagrammed the way of logical statement and presented articles of observance in making a definition of home economics. Next the two modes of statement have been compared with each other. And some problems of defining home economics have been found out Finally, based on the mode of logical statement, some new definitions of home economics have been suggested for future growth of home economics.

Triple-reflection system of the dielectric coated metallic mirror acts as retarder, by proper selection of film refractive index, film thickness, and angle of incidence, that maintains collinearity of the input and output beams. If the film refractive index and angle of incidence are given, then the design procedure is described to determine the film thickness at design wavelength. Example is presented of quarterwave retarder that uses a ZnS-Ag film substrate system at the CO_2 laser wavelength. The equal net reflectances for p and s polarizations are computed and found to be high. Also the useful operation over a small wavelength range is demonstrated.

The purpose of this study was to investigate the kinematical and ground reaction force variables according to the trunk lean[type A : 0~4deg., type B : 6~12deg.) during the stair ascent. For thi experiment, the stair structure was made and AMTI force plate was installed on the second and third stepping. Each motion was videotaped and digitalized with five video cameras to calculated the kinematical variables, and at the same time collected the ground reaction force. As a result, the following findings were obtained: 1. It was found that gait cycle of the type A was longer than type B, but ratio of the stance and swing to the gait cycle was similar to each other. Also it was found that stair ascent of the type A was more effective than that type B in the lower extremity motion. 2. It was found that stair ascent of the type A in the vertical and antero-posterior ground reaction force variables was more effective than that type B in that ascending the body weight.

In this study, a vehicle vector using cryptic plasmids was constructed for gene transfer in Helicobacter pylori. pHP51(3.9 kb) and pHP489(1.2 kb) were selected for constructing vectors from cryptic plasmid of H. pylori isolates in Korea. The HindⅢ-digestedDNA fragment(1.2kb) of pHP489 and 1.6kb DNA fragment of pHP51 were ligated with a kanamycin resistance gene(aph3'-Ⅲ) from C. jejuni to produce the recombinant plasmids pHP489K and pHP51K, respectively. Transformation frequency of pHP51K by electroporation was low. But pHP489K could be effectively transformed into various H. pylori strains. In order to design an intermdiate vehicle vector for gene transfer into H. pylori, pBlueHP489K was prepared by recloning pHP489K DNA into pBluescript and pTZ19R vector. This vector permitted the DNA fragment containing pHP489 sequence, aph3'-Ⅲ, and cloned DNA to be cut and self-ligated in the SacⅠ site after cloning. ureA and ureB gene were inserted into pBlueHP489K, resulting in pBlueHP489K/AB. The DNA fragment containing pHP489, kanamycin resistance gene(aph3'-Ⅲ), and urease structural gene was cut away from pBlueHP489K/AB and self-ligated to generate pBlueHP489K/AB. pBlueHP489K/AB made urease-negative H. pylori strains restore their urease activity. By this experiment, pBlueHP489K was confirmed to be the vehicle system for transferring H. pylori genes.

The aim of this research is to set improvement guidance a character analysis of woodland edge to cope with the ecological dysfunction of woodland which was caused by massive development project and thoughtless development in country areas. The summary of research result are as follows. 1) From the result of landscape ecology characteristic analysis of woodland in all seven research sites, to begin with, in proportion of appearance by vegetation layer and condition of composition, site 5 showed to be most satisfactory. 2) A width of woodland edge was revealed 7.5m as a minimum, 17.0m as a maximum, and 11.4m as a average and minimum edge was set as 10m according to integrated analysis on each example place. 3) As a result of flexibility analysis, site 1, 2 and 5 was shown high value 3, and it is thought that curve rather than linearity should be maintained in order to increase the ecological function. Also, a phenomenon of straight was prominent, and as a woodland edge, green network and buffering system showed to be somewhat unsatisfactory. 4) Based on the result of character analysis of landscape ecology, main guidelines for improvement of woodland edge were categorized into five in parallel structure and three in vertical structure respectively. The guidelines for improvement of woodland edge suggested by the research has a deep meaning in that it is used as a basic material to induce for controling more systematically or landscape-friendly the defamed forest problems caused by road construction, various development projects, and enlargement of agricultural lands.

Subcutaneous injection of cells from renal adenocarcinoma line, renca, into Balb/c mice induces fast growing solid tumors. This method has been used to speculate the efficacy of cytokine treatment for tumor regression. The present study was designed to investigate the effect of treadmill exercise on tumor growth using renca mouse tumor model. We also examined the expression pattern of several genes related to immune response after exercise training for 4 weeks. Exercise training reduced the size of tumor mass compared to that of non-exercised group in tumor cell recipient mice. Natural killer(NK) cell activity showed no significant difference between exercised and non-exercised groups in tumor cell non-recipient mice. Although NK cell activity of non-recipients was higher than tumor cell recipients, NK cell activity of exercised group was significantly lower than non-exercised group among tumor cell recipients. There were no significant differences in mRNA expressions of cytokines. scavenger receptors, and neuropeptieds which are related to immune response, while mRNA expression of TGF-beta was significantly reduced both in spleen and in tumor mass by treadmill exercise. Based on the results presented in this study, endurance exercise has shown the possibility to suppress tumor formation.

본 연구의 목적은 중등 가정과 교사들의 다문화적 태도, 다문화 교육 실천 효능감, 다문화 교육 목표 관점에 대한 인식을 조사하고, 세 하위척도가 각각 어떠한 상관관계가 있는지 알아본 것이다. 연구 대상은 중등 가정과 교사들 130명이며, 양적 연구를 통해 분석한 결과는 다음과 같다. 첫째, 중등 가정과 교사들은 현행 교육과정에서 다문화주의와 다양성을 미흡하게 다루고 있다 고 인식하고 있었으나, 다문화 관련 학부 수강 경험이 거의 없거나 연수를 받지 않은 것으로 나타났다. 이에 다문화 교육을 위한 교사 교육의 강화가 시급하다. 둘째, 중등 가정과 교사들은 다문화 교육 실천 효능감에 대한 인식들 중에서 다문화 교실에 적합한 학습 자료의 개발과 수업방법 적용 측면에서 특히 낮은 효능감을 나타내었으며, 이에 대한 교사 의 자발적인 노력과 행정적인 지원이 수반 되어야 할 것이다. 셋째, 중등 가정과 교사들의 다문화 교육 목표에 대한 관점은 사회적 행동 지향적, 배려중심 지 향적 목표를 중점적으로 동의하는 것으로 나타났다. 넷째, 다문화적 태도, 다문화 교육 실천 효능감, 다문화 교육 목표에 대한 관점의 상관관계를 살 펴본 결과, 사회적 행동 지향적 목표는 다문화적 태도에, 배려중심 지향적 목표는 다문화교육 실천 효능감에 영향을 주는 예측변인으로 나타났고, 다문화적 태도와 다문화 교육 실천 효능감이 사회 적 행동 지향적 목표와 배려 중심 지향적 목표에 영향을 주는 예측변인으로 나타났다. 그러므로 교 사들이 추구해야 할 목표는 현상유지의 관점을 공유하는 것이 아닌 변혁적인 교실 수업을 지향하는 관점을 추구해야 할 것이다. This study is intended to investigate Homes Economics teachers' multicultural attitudes and teaching practice self-efficacy, and their awareness of the objectives of multi-cultural education. The study also aims to find how these three elements are correlated with each other. For these purposes, one hundred thirty Homes Economics teachers were surveyed employing a questionnaire and the data obtained were analyzed quantitatively. The main findings are as follows. First, Homes Economics teachers perceived that the current curriculum does not deal with multiculturalism and diversity sufficiently. However, they took few courses related to multiculturalism in their undergraduate courses. They also had few opportunities of being trained on multiculturalism since they started to work as teachers. Thus, it is urgent for teachers to be educated or trained in multiculturalism. Second, as for their perception of teaching practice self efficacy of multiculturalism, Homes Economics teachers showed a low level of self efficacy especially in developing and applying teaching materials and methods suitable for multicultural classes. Therefore, Homes Economics teachers are required to make voluntary efforts to create and practice multicultural teaching materials and methods. In addition, administrative support is urgently needed to promote their efforts. Third, as for Homes Economics teachers' perspectives on the objectives of multicultural education, theyprimarily agreed to objectives oriented toward social behaviors and considerateness. Finally, an examination of the correlation between Homes Economics teachers' multicultural attitudes, their multicultural teaching efficacy and their perspectives of objectives for multicultural education led to the following: the objective oriented toward social behaviors was found to be a prediction variable of multicultural attitudes, and the objective oriented to considerateness was shown to be a prediction variable of multicultural efficacy. Therefore, Homes Economics teachers are required to have the perspective of seeking innovative classes instead of sharing the perspective of maintaining the current status.

Background and Objectives : Chronic suppurative otitis media is one of the frequent diseases in otolaryngologic field. It is important to choose of antibiotics in the management of infectious disease. But the organisms in infections have been changed and resistance to antibiotics has been grown as the development of antibiotics has been achieved. And so it has been necessary to recognize the changes of organisms and resistance in antibiotics. Our study was performed to identify the pathogens isolated from discharges in chronic otitis media and evaluate the antibiotic agents, to recognize the change of to resistance to·antibiotic agents and to use the appropriate anitiotics. Materials and Methods : Retrospectively, authors reviewed the backeriologic study of 114 cases of chronic suppurative otitis media who visited the Department of Otolaryngology, Soonchunhyang University in Seoul from Nov. 1996 to Oct. 1999 and analyzed 101 strains and its sensitivity test to various antibiotics. Result : In 93 cases in which pathogenic organism was isolated, single infection was 85 cases(91.4%) and mixed infection was 8 cases(8.6%). The most frequent pathogenic organism was Staphylococcus aureus(59.4%), Pseudomonas aeruginosa(13.9%), Providencia(4.8%), Alcaligenes(3.0%) and Streptococcus pneumoniae(2.9%) were the next. Methicilline-Resistance Staphylococcus aureus was 34 cases(57.6%) of Staphylococcus aureus. Staphylococcus aureus was sensitive to Vancomycin(96.7%), Trimethoprim-Sulfamethoxazole (57.6%), Cefuroxime(42.4%) and Ciprofloxacin(40.7%) but resistant to Penicillin(94.9%). Pseudomonas aeruginosa was sentitive Amikacin(100%), Ciprofloxacin(100%) and Gentamicin(67%). Conclusion : As MRSA recently was wide spread in community accquired infection as well as nosocomial infection, we must consider strict control of MRSA.
