조형수 경기대학교 교육대학원 1998 경기교육논총 Vol.7 No.-

본 연구는 레포츠에 참여하는 동호인들의 여가 만족도를 규명하는데 주된 목적이 있다. 본 연구의 대상은 서울시 소재 레저스포츠 동호인으로 레저스포츠 클럽에 소속되어 있는 전문인과 레저이벤트 관련 업체의 레저스포츠 분야에서 직접 활동하고 있는 동호인 500명이었다. 본 연구에서 사용한 설문지의 신뢰도 분석결과 신뢰도 계수는 α= .79-.93범주로 비교적 높게 나타났다. 이와 같은 결과는 본 연구에서 신뢰성이 높다는 것을 시사해주고 있다. 회수된 설문지는 통계 패케이지 프로그램인 SAS와 IBM PC 586 기종을 이용하여 분석하였으며, 분석에 이용된 통계기법은 신뢰도분석(Reliability analysis), 상관관계 분석(Correlation analysis)과 다중회귀 분석(Multiple Regression analysis) 등이었다. 위와 같은 연구절차를 통하여 본 연구에서 도출한 결론은 다음과 같다. 첫째, 레포츠에 참여하는 동호인들의 참여빈도는 여가만족도에 영향을 미친다. 둘째. 레포츠에 참여하는 동호인들의 참여강도는 여가만족도에 영향을 미치지 않는다. 셋째, 레포츠에 참여하는 동호인들의 참여기간은 여가만족도에 영향을 미친다. 넷째. 레포츠에 참여하는 동호인들의 참여비용은 여가만족도에 영향을 미치지 않는다. The purpose of this study is to scrutinize and confirm the correlation between Leisure Satisfaction with Participants to Leisure Sport. A group of about 500 experts and participants. Who are either enrolled in Leisure Sports clubs in Seoul or working in organizations relevant to Leisure Sport, such as many event Companies were chosen to be surveyed. SAS(Static package program) involving reliability analysis, multiple regression analysis. Correlation analysis, etc. is used to compare and analyze the outcome of the survey. Furthermore with cross-examination, Cronbach's α turned out to be up to α=.79∼.93, which is relatively high, and what it means is that the process of analysis is highly reliable. The following conclusions can be drawn : 1. The frequency of participation in Leisure Sport affects the Leisure Satisfaction 2. The intensity of participation in Leisure Sport doesn't affects the Leisure Satisfaction to sport 3. The duration of participation in Leisure Sport affects the Leisure Satisfaction 4. The cost of participation in Leisure Sport doesn't affects the Leisure Satisfaction

Photonic crystal fibers(PCFs) with silica cores within an away of air holes have unique properties. Broad band single-mode and the octave-spanning supercontinuum generation, impossible to achieve in classical fibers, can be realized. The design of PCFs is very flexible. There are two parameters to manipulate: air hole diameter, and lattice pitch. We introduced a fabrication process for control of the parameters to obtain endlessly single mode PCF, which is single mode in a large wavelength range, and highly nonlinear PCF. The numerical analysis and experiments are included. 실리카 코어 주변에 주기적인 공기층을 가지는 광자결정 광섬유는 넓은 파장 영역을 통한 단일모드의 구현 또는 1옥타브 이상의 광대역 연속광 발생과 같은 기존의 광섬유로는 불가능한 독특한 특성을 갖도록 유연하게 설계할 수 있다. 광자결정 광섬유의 설계에 사용되는 변수로는 공기층의 직경과 간격이 있으며 이러한 변수의 조절을 위한 공정을 도입하여 넓은 파장영역을 통한 단일모드 구현과 높은 비선형 특성을 가지는 광자결정 광섬유를 각각 제작 하였고 수치적 계산과 실험을 통해 그 특성을 살펴보았다.

Hydroxyapatite-coated 임프란트의 골유착에 관한 문헌적 고찰

조형수 朝鮮大學校 口腔生物學硏究所 1999 Oral Biology Research (Oral Biol Res) Vol.23 No.1

Hydroxyapatie-coated(HA-coated) endosseous implant in the treatment of dental patients has been used clinically for almost 20 years, but their clinical predictability remains controversial. This study reviews an analysis of the biochemical composition of commercial HA coating in relation to in vivo predictability, potential concerns, and potential advantages of HA coating, and the clinical predictability and indications for use of HA-coated implants. The majority of data suggest that HA-coated implants are as predictable clinically as titanium implants in short-term periods(6 months to 6 years), and they may be useful treatment modalities in a variety of clinical situations such as 1) in bone quality type IV, 2) in shorter implants (less than or equal to 10㎜), 3) in fresh extraction sites(immediate implants), and 4) in case graft-augmented maxillary and nasal sinuses, but long-term studies are required to validate these observations.

Implant stability is the key to long-term successful outcome for osseointegrated implants. To evaluate the initial healing response of bone around HA-coated implants without primary bone contact. 21 HA-coated thread type implants(STERI-OSS?) were placed in the femurs of 5 mongrel dogs, about 1-year old. Implants, 8 mm in length and 3.8mm(experimental 1group), 5.0mm(experimental 2group) and 6.0mm(control group) in diameter, were inserted after 3 holes of 6.0mm in diameter and 10mm in depth were prepared in the surgical sites each dog. Implants were supported by only nonresorbable membrane($Teflon^{(R)}$), in order to prevent the ingrowth of upper soft tissue into the gap between bone and implant, and to maintain each implant to be positioned in the center of the drilled hole. 9 implants with different diameters were inserted in 3 dogs for histologic observation, and 12 implants were inserted in 2 dogs for mobility test and removal torque test. Fluorescent dyes were injected for the observation of new bone formation in order of $Terramycin^{(R)}$, Arizarin $Red^{(R)}$, and $Calcein^{(R)}$ at an interval of 2 weeks. 3 dogs were sacrificed for histologic observation at 4, 8, and 12-week after placement. Light microscopy and confocal laser scanning microscopy were used to qualitatively characterize the bone around HA-coated implant. 2 dogs were sacrificed for mobility test($Periotest^{(R)}$, Simens AG, Bensheim, Germany) and removal torque test($Autograph^{(R)}$ AGS-1000D series, Japan) at 8 and 12-week after placement The results were as follows: 1. Histologic observation showed that osseointegration occurred to both control and experimental groups as time lapse, but delayed bone healing was revealed in 3.8mm group (experimental 1group), compared to contrtol group and 5.0mm group (experimental 2group). 2. The mobility test showed that the experimental groups had no distinguishable movement during experimental periods of 8 and 12-week, and there was no difference in mobility depending on the gap between bone and implant, and time lapse. 3. The removal torque forces were increased depended on the gaps decreasing between bone and implant, and time lapse. The results suggest that HA-coated implant without primary bone contact, based on guided bone regeneration could obtain its stability in all experimental groups as time lapse, but bone healing was delayed in experimental group of 3.8mm. And the results suggested that studies on correlationship between mobility test and removal torque test for implant stability would be necessary.

The purpose of the study was to assess the extent to which the sports insustry was affected by economic growth during the 1982-2002. The annual fugures for these variables were derived from several government and nongovernment publications, and changes were used in simple regression analysis. The positive correlations with the sports insustry were found in the coefficients of real per capita GNI. The negative correlations with the sports insustry were found in the coefficients of working hours, unemployment rate., working hours. The higher correlation among the variables in the general economy were found between real per capita GNI and working hours. Analysis indicate that the trend in value of the sports industry was affected by real per capita GNI. Subsequent analysis of the individual sports sector in the industry demonstrated positive correlation with real per capita GNI.
