The purpose of this research was to reveal differences in advertisement effects between official sponsors and ambushing marketing companies, in the aspects of the attitudes in advertisements about company, product goodwill degree, purchasing intentions, company images, and changed consumer attitudes after ambush marketing were verified, establishing concepts through theoretical surveying previous researches about ambush marketing and through practical and experimental analysis. The results of those practical analysis were outlined below: Domestic consumers generally had positive recognitions about official sponsors and trusted them, but they could not easily differentiate ambush marketing from official advertisements due to barely understanding what official sponsors are. That reason was that they were difficult to recognize official sponsors in advertisements. Furthermore, respondents to the questionnaire did not change their positive attitudes towards advertisements after recognizing the fact that official sponsors they had thought were in fact ambush marketing. Therefore there were no or little differences between ambush marketing and official sponsors in the aspects of the attitudes in advertisements about company, product attitudes, purchasing intentions, and company images.

학교 체육과 생활 체육의 보완적 연계를 통한 중학교 체육과 교육과정의 효율적 운영 방안

이표상 한국학교체육학회 2004 한국학교 체육학회지 Vol.14 No.1

본 연구는 학교 체육과 생활 체육의 상호보완적 연계를 통해 중학교 체육과 교육과정의 효율적 운영 방안들을 탐색하는 데 초점을 맞추어 관련 선행연구와 보고자료 및 참고문헌을 토대로 다음과 같은 방안을 모색하였다. 첫째, 학교 체육과 생활 체육 두 영역간의 양태에 따른 연계 방식에서 차별적, 통합적, 보완적 연계 방식 중, 현실적인 상황에서 보완적 연계 방식이 가장 바람직한 방안으로 생각된다. 둘째, 학교 체육은 '학교'와 '수업'의 테두리 내에서 교육적 이상의 한 부분에 '생활'과 '실용 중심적인 것'을 포용하는 방식의 변용이 필요하고, 생활 체육은 학교 밖의 울타리를 벗어나 '생활적인 점'을 부각하고 '외재적이고 실용적인 특징'에서 인성함양, 안목개발, 자아실현 등 학교체육의 내재적 가치를 달성하기 위해 사회교육의 성격을 가미한 변용이 필요하다. 셋째, 인접지 지역 생활 체육시설 이용에서 나타나는 문제점인 '이동상의 비용이성' 그리고 '비근접성' 같은 문제점을 해결하기 위해서 지역 생활 체육시설뿐만 아니라 학사일정과 교과내용에 따라 대학 내의 체육시설 그리고 타 학교 체윽시설 활용 방안을 고려할 필요가 있다. 또한 이동수업시 예상되는 안전사고에 대한 문제는 현재 운영중인 학교 안전공제회의 법적 적용 범위가 확대되어 안전사고의 책임으로부터 보호받을 수 있도록 하여 창의적이고 의욕적인 교육활동이 위축되지 않도록 제도적 장치가 우선되어야 할 것으로 생각된다. 넷째, 인접지 지역 생활 체육 자원을 적극 활용하기 위해서는 대안적 체육과 교육과정 운영에 따른 체육수업시간의 통합적 운영이 절대적으로 필요하다. 다섯째, 체육수업의 질적 향상을 제고하기 위해서는 연간프로그램의 계획과 실행에서 생활체육지도자와 공동 참여를 통해 수업시간의 협동적 운영, 학습자 관리, 지도내용과 교수 학습방법의 부문에서 유기적인 정보공유와 교류를 필요로 하며, 이와 같은 인적 자원 활용은 중학교 체육과 교육과정의 효율적 운영에 긍정적 영향을 미칠 것이라 기대된다. This study focuses on making an efficient Programs for middle school physical education's curriculum through complementary connection of school physical education and life sports. With reference to related advance research, report and reference, this study designs the following plans in terms of conceptive plan for connection of school physical education to life sports and complement-enabled area in detail, based on curricular physical education class. First, among differential, integrated and complementary connection methods in accordance with pattern between school physical education and life sports, it is expected that complementary connection will be realistically desirable. Second, school physical education is required to include 'life' and 'practicality' in light of idealistic education within the scope of 'school' and 'class'. On the contrary, life sports need to add social education so as to place stress on 'life activity' out of school and search for internal values of school physical education, i.e., personality cultivation, insight development, self-realization out of `external and practical characteristics'. Third, in order to solve problems such as 'uneasy movement' and 'inaccessibility' that may occur when using athletic facilities in neighboring cities, campus athletic facilities as well as local athletic facilities should be available according to education schedule and it may be required to utilize athletic facilities at other universities. For problems about accidents that may occur during mobile class, it is necessary to extend legal scope of application of School Safety Fraternal Association currently in operation so as to protect from accidents and also required to create institutional frameworks to prevent creative and motivated education activities from being shrunk. Fourth, in order to make the best use of local athletic facilities in neighboring areas, it is required to manage physical education class according to alternative education and curriculum operation. Fifth, so as to increase the quality of physical education class, it is required to cooperatively operate class, manage learners, share and exchange information in the area of guidance, teaching method through joint participation of life sports leaders in annual programs. Such utilization of human resources in neighboring area is considered as important factor that may have positive effects upon the efficient operation of middle school physical education's curriculum.

The purpose of this study was to examine if previous studies on socio- active adaptation of androgynous identity types is useful in an andocentric ROTC group environment specifically from the perspective of gender integration. For this purpose, participants were classified in four categories according to type of gender role identity of men and women, perception level of Physical Self-Efficacy Scales (PSES) by type and the differences in Physical Training Test Scores (PTTS) were analyzed. Participants in the current study include 172 volunteer undergraduate students (84 males and 86 females) participating as cadets in the Texas A&M University Corps of Cadets. The study found males PSES perceptions, masculinity and androgyny identity had higher perception levels than other types. Therefore, the first hypothesis, that the perception level on the PSES of the androgynous type is higher or the same that of the masculine type was supported for the male students. In the case of female students, it was shown that the perception level of the androgyny type was higher than that of other types. Therefore, the first hypothesis was also supported for female students. The difference of the males PTTS by the type of gender role identity was analyzed. The study found that masculine identity type scored higher than other types. Therefore, the second hypothesis, that the androgyny type will lead to better PTTS scores, was not supported for male students. In case of female students, differences were observed among the masculinity, femininity and unclassified types. The androgyny type was different from the femininity and unclassified type. However, the mean difference between the masculinity types was not observed. The second hypothesis was accepted for female students. An interesting similarity between the two types was considered to be the homogeneous group attributes between the two types. As a result, the researcher contends that both masculinity identity and androgyny identity will be useful psychological health index in an ROTC environment.

The purpose of this study was to observe the effect of TGF-81, which promotes differentiation and proliferation of osteoblasts, on bone regeneration. Experimental bone defects that measured 3 mm in diameter were created on the mandibles of guinea pig by removal of bone with the use of trephine burs. In one side of mandibular body, the experimental groups, bone defects were grafted with Biogran(Orthovita Co., U.S.A.) and TGF 131(R&D System Co., U.S.A.). In the remaining side of the mandiblar body, the control groups, bone defects were grafted with only Biogran. Guinea pigs in the control and experimental groups were serially terminated by fours on the 3 days, the 1 week, the 2 weeks, the 3 weeks, and the 4 weeks after experiment, and both sides of the mandibular bodies were removed and fixed with 10% neutral formalin. They were decalcified and embedded in paraffin as using the usual method. The specimen sectioned and stained with hematoxylin and eosin. Also, they were radiographed with a soft X-ray apparatus. The Obtained results.=were as follows; 1. Hemorrhagic condition, observed in the granulation tissues, disappeared on the 1 week after experiment in both groups, and more prominent in the experimental group. The granulation tissues of the experimental group had larger number of cells than those of the control group. 2. Osteoblastic differentiation in the margin of grafted material and adjacent bone was observed on the 1 week after experiment in both groups. Also, bone formation was observed in immature form on the 1 week after experiment, and more prominent in the experimental group. 3. In the polarizing microscopic examination, bone matrix was very loose on the 1 week after experiment, but increase in density with time, and more prominent in the experimental group. 4. In the microradiographic examination, newly formed bone was observed in the experimental group on the 2 weeks after experiment, and this was observed earlier than in the control group. Newly formed bone was increased with time and defected area was markedly decreased on the 4 weeks after experiment.

Fe₂SiO₄에 관한 X-선 회절실험과 Mossbauer 분광실험을 하였다. X-선 회절실험 결과 본 시료는 olivine group에 속하는 fayalite로서 orthorhombic 구조(??)임을 알 수 있었다. Mossbauer 분광실험은 60K-834K의 온도구간에서 행하여 졌으며, Mossbaure 스펙트럼을 분석한 결과 철은 high spin 2+ 상태임을 알 수 있었고, X-선 회절실험 결과와는 다르게 철이 산소 이온들과 함께 일그러진 octahedron을 형성하고 있음을 알 수 있었다. The Fe₂SiO₄ has been studied by means of X-ray diffractometry and Mossbauer spectroscopy. The analysis of X-ray diffraction pattern shows that Fe₂SiO₄is fayalite of orthorhombic structure(??). The Mossbauer spectra which have been taken between 60K and 834K show that the valence state of iron is ferrous and high spin state and that the iron ions occupy sites of distorted octahedron whereas the X-ray analysis shows it is at a site of regular one.

There is a need to improve the efficiency of the existing sanitary treatment facilities, because the effluent standard becomes more stricter and septic sludge increased. Thus, operating processes of sanitary treatment system in M city changed with installation of additional facilities. Process modifications were as follows: Dilution water was added to the next process after primary aeration tank. Some secondary sedimentation sludge was recycled to primary aerator so that most of the organics were stabilized in primary aeration tank under automatic control of dissolved oxygen. The line of effluent from dewatering process flowing to the activated sludge tank was changed to the primary aerator. The primary sedimentation sludge line was linked to a thickener. Polymer was added to the activated sludge tank. The effluent of primary aerator and aerobic digester was recycled from the 5th to the 1st sector. As consequencies of above process modifications, the improvement of removal efficiency was achieved as BOD 54%, COD 42%, SS 61%, T-N 39%, and T-P 12%, respectively.
