Six gymnast of subjects (more than nine years of the gymnastic experienced) draw from P. city were utilized in this study. The purpose of this study was to find out the relationship between the takeoff stride and the takeoff force and the first peakforce and the second peakforce through the aid of cinematography and the force platform at the Tsukahara stretched. Also, relationship between the pre-flight (from the takeoff stride at board to horse contact) and post-flight (from contact horse to the first peak), displacement of center of gravity, and time from takeoff to the first peak were analyzed. From the data provide, kinematic analysis of Tsukahara stretched from board at vaulting horse. The conclusions are as follows : 1. It was found that subjects had shorter preflight distance than approach distance and longer board takeoff. 2. It was found that shorter support time of the first peakforce and the second peakforce, elevation of both force, and reduction of difference between both force with an instant stretch of knee is desirable to get more flight. 3. It was revealed that shorter time between contact horse and takeoff horse with an instant push horse back increased the turning power and time in the air then effects on flight distance. The flight distance was found gymnast B, A, F, E, C, and D, as order. So gymnast D. was the best record. 4. Gymnast B. C. E. and F. had the lower first peak stance, unstability, and shorter flight distance so their score were reduced.

목적: 본 연구는 만성 요통근로자의 세 가지 능동적 운동프로그램 효과에 관한 연구로서 능동적 운동이 요추의 안정성 향상에 미치는 영향을 알아보고자 시도되었다. 방법: 3개월 이상 만성요통을 호소하는 64명의 근로자대상으로 무작위로 일반적인 물리치료그룹, 요추 운동그룹, 흉추 운동그룹, 세 그룹으로 나누었다. 능동적 운동 프로그램은 주 3회, 6개월 동안 실시하였으며, 통증강도, Oswestry 장애지수, 양손을 머리위로 최대한 올려 높이 측정, 요추부 경사각도를 평가하였다. 모든 대상자들은 연구 전, 연구 후 2주, 3개월, 6개월을 같은 측정방법으로 재평가하였다. 결과: 통증강도는 세 그룹 간에 통계적으로 유의한 차이가 없었다. Oswestry 장애지수는 연구 후 6개월에서 세 그룹 간의 유의한 차이가 있었으며, 요추운동그룹과 흉추운동그룹이 일반적인 물리치료그룹에 비하여 유의하게 감소하였다(p<0.05). 양손을 머리위로 최대한 올려 높이측정은 연구 후 3개월과 6개월에서 세 그룹 간에 유의한 차이가 있었으며, 연구 후 6개월에서는 흉추운동그룹이 일반적인 물리치료그룹과 요추운동그룹에 비하여 유의하게 증가하였다(p<0.05). 요추부 경사각도는 연구 후 2주와 3개월, 6개월에서 세 그룹 간에 유의한 차이가 있었으며, 연구 후 6개월에서는 흉추운동그룹이 일반적인 물리치료그룹과 요추운동그룹에 비하여 유의하게 감소하였다(p<0.05). 결론: 3개월 이상 만성 요통을 호소하는 근로자 대상으로 흉추의 운동성 증가를 위한 운동프로그램을 적용하여 흉추의 운동성을 증가시킨 결과에서 보면, 2주 시행하였을 때 요추의 신전 운동프로그램 보다 요추의 안정성 향상에 효과적이며, 6개월 시행하였을 때만, 요추의 심부근 근력강화 운동프로그램보다 요추의 안정성 향상에 효과적이었다. Oswestry 장애지수는 요추의 심부근 근력강화 운동프로그램과 동일하게 감소하였고, 통증강도는 세 그룹 모두 2주 시행하였을 때 감소하는 것으로 나타났다. Objective: To examine the relative efficacy of three active exercise programs for work-related, chronic low back pain, and to observe to what extent the programs affected the mechanical stability of the lumbar region. Methods: The subjects were 64 employees who were randomly divided into three groups to match the three active exercise programs which were performed 3 times a week for 6 months. All subjects were assessed with the same measurements at a pre-study examination, and then were reassessed at 2 weeks, 3 months and 6 months after the study. Results: The pain intensity didn' t show any significant difference among the three groups. However, the Oswestry Disability Index showed significant differences among the three groups at 6 months and the lumbar and thoracic exercise groups showed significant decreases compared to the general physiotherapy group (p<0.05). Maximal stretching with both hands in the overhead direction showed a significant difference among the three groups at 3 months and 6 months, and the thoracic exercise group at 6 months showed a significant increase in overhead stretching compared to the lumbar exercise and general physiotherapy groups (p<0.05). The lumbar region angle of inclination showed significant differences among the three groups at 2 weeks, 3 months and 6 months, with the thoracic exercise group being decreased significantly more than the lumbar exercise and general physiotherapy groups at 6 months (p<0.05). Conclusions: Exercise aimed at increasing thoracic mobility has an effect on lumbar stability. Furthermore, it is far more effective for lumbar stabilization than general physiotherapy and deep muscle strengthening lumbar exercise.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

The purpose of this study was to compare shear bond strength and interfacial pattern of composite bonded to dentin using self-etching adhesive systems. Sixty extracted human molars with exposed occlusal dentin were divided into four groups and bonded with four adhesives and composites: Single Bond/Filtek Z 250(SB), Tyrian SPE-One-Step Plus/Aelitefil(TY), Prompt L-Lpop/Filtek Z 250(LP), and one-Up Bond F/Palfique Toughwell(OU). The results of this study were as follows; 1. Shear bond strength for OU was significantly lowet than that of other groups(p<0.05). No significant difference was founded among SB, TY, and LP. 2. Failure modes to dentin showed adhesive and mixed for SB, TY, and LP, but them for OUT showed adhesive in all spceimens. 3. Dentin-resin interface showed close adaptation for SB, TY, and LP, but it showed gap for OU. 4. The hybrid layers for TY, LP, OU were thinner than that of SB. Adhesive layers were observed between composite and hybrid layer, which were 5 ㎛ thick for TY and 10 ㎛ thick for OU.

?? -tree is widely used as index structure in information retrieval system such as digital library and World-Wide Web information retrieval engine. The Information retrieval ststem often reflect all information collected independently by robot agent into their current indexes and directories at one time. When many key values are inserted into an index implemented as ?? -tree, much processing time will be required to search and to split nodes to look for the leaf nodes inserted. In order to Solve this problem, in this paper, we propose BULK_ADD strategy which creates a new ?? -tree by merging the existing ?? -tree and the set of data to be inserted. We also analyze performance of proposed BULK-ADD strategy. From the performance analysis, we found that the proposed strategy has better performance than the algorithm which inserts repeatedly into ?? -tree, when the nember of inserted data objects is over specific ratio(4%) of the existing index size. This ratio can be used as the criteria selecting the scheme to insert multiple data objects into ?? -tree with the minimum processing time in information scheme to insert multiple data objects into ?? -tree with the minimum processing time in information retrieval systems. At the same time, the period of index update can be determined on the basis of this ratio, if we can predict the data quantity newly collected during a specific time interval.
