The purpose of this study was to investigate the difference in swing time by phase by analyzing forehand and backhand stroke, expert and amateur, practice and actual swing of tennis and to help learner for efficient motion. The results of the study were as follow: Backswing time of forehand stroke. there were differences between 2 groups and 2 types of swing(1.182±0.174sec for practice swing of amateur. 1.022±0.105sec for actual swing of amateur. 0.882±0.039sec for practice swing of expert, 0.855±0.050sec for actual swing of expert). Forward swing time of forehand stroke, there were differences(0.405±0.036sec for practice swing of amateur, 0.303±0.053sec for actual swing of amateur, 0.435±0.025sec for practice swing of expert. 0.407± 0.024sec for actual swing of expert).

Structural and mechanical adaptations of the femur and tibia to jump and run training were investigated in female Fischer 344 rats. Rats aged 4 week were trained for 8 weeks after 1 week of stabilization. In experiment A, the forced run-trained (speed : 30m/min, duration : lh/day)group was compared with the control group. In experiment B, voluntary run and jump-trained (height : 40㎝, 100 times/day) group were compared with the control group. The limb bones of the jump-trained group had greater cross-sectional areas and greater maximum load in a fracture test than the limb bones of the control group, but there was no significant difference in bone length between the jump-trained group and the controls. The bone adaptations to forced running and voluntary running were similar. The limb bones of both run groups were longer than those of each control group. The cross-sectional areas and the maximum load in the run-trained groups were greater than those in each control group but less than those in the jump-trained group. The present results indicate that bone adaptations to jump training and run training differ and that jump training is more effective for building stronger bones.

The purpose of this study was to classify and analyze the H.C.G of elementary school students by ages, genders, and Broca's index. And provide the efficient basic data for elite players and sports leaders by adapting the conception of H.C.G at the real educational situation. The subject of this study was 3,000 elementary school students in K area. They were selected by stratified sampling process. The equipment of measure was reaction board(length 2m 10cm. width 1m. thickness 36mm) system. The main variables related with H.C.G. were selected by ages, genders, Broca's index. And SPSS-PC program(ver 10.0) was used for verifying the datas obtained from measurement(p<.05). The conclusions were as follows. 1) H.C.G by Broca's index were from 84.02cm(extreme shorted weight) to 73.30cm(fatness). P.C.G by Broca's index were the highest in fatness(57.20%) and the lowest in extreme shorted weight(56.45%). It was statistically valuable(p<.05). 2) H.C.G by Broca's index and genders were from 83.75cm(extreme shorted weight) to 75.00cm(fatness) in case of male and from 84.29cm(extreme shorted weight) to 72.10cm(fatness) in case of female. P.C.G by Broca's index and genders were the lowest (56.42%-extreme shortes weight) and the highest (57.21%-fatness) in case of male, and the lowest(56.49%-extreme shorted weight) and the highest(57.17%-fatness) in case of female. It was statistically valuable(p<.05). 3) H.C.G by Broca's index and ages were largely high in extreme shorted weight and largely low in fatness, but P.C.G by Broca's index and ages were more higher in fatness. It was statistically valuable(p<.05).

본 연구의 목적은 사회복지조직의 공개 채용공고가 실제채용기준을 얼마나 반영하고 있는지 파악하여 채용공고의 변화가능성을 탐색하기 위함이다. 이러한 목적을 달성하기 위해 2008년 한국사회복지사협회의 채용공고 중 210건의 조직을 표집하여 기초분석을 통해 정보내용을 파악하였고, 서울과 대전의 23개 조직의 기관장을 대상으로 1:1면접을 통해 사례연구를 진행하였다. 분석결과, 실제채용기준은 자원봉사와 실습을 통한 현장경험, 사회복지사 1급 자격증, 지원자와 조직의 비전 일치, 사회복지 마인드, 대인관계 등으로 드러났다. 그러나 이는 채용공고에 제시되지 않거나 질적인 차이를 보였다. The purpose of this study is to understand how an open employment notice has reflected the actual criterions of the recruitment, and to discover a potential for any changes. To achieve this purpose, a systematic random sample of 210 open employment notices was selected from Korea Association of Social Workers in 2008, and a descriptive analysis was conducted. The qualitative research was carried out for the case study with 23 interviewees from social welfare organizations in Seoul and Daejeon. Consequently, the actual criterions of the recruitment included the following elements: social work field practicum and volunteer work, the level one social welfare license, degree of harmony with the vision of the organization, dept of social welfare-oriented mind, and human networks. However, these criterions may not be presented in open employment notices or show that there are qualitative differences between open employment notices and the actual employment criterions.

Purpose: The purpose of this study is to evaluate the knowledge and attitudes of oncology ward nurses toward cancer pain management and to find ways to improve the educational program for nurses. Method: A total of 209 nurses working at the oncology ward of three hospitals in Seoul and a Gyenggi Province. The survey instrument used was the 32-item scale for evaluating nurses knowledge and attitudes originally developed by McCaffery and Ferrell'(1990). that was by Kim'(1997). Result: In terms of the nurses knowledge of pain management. the result showed that the nurses scored an average of 67.8 out of 100 for phamacokinetics of opioids. 84.8 for classification of analgesics, 60.1 for pain assessment, and 70.7 for drug administration. 18.2% of the nurses hesitate to inject the narcotic agent because of concerns regarding the drug's potential side effects. there was significant difference in the knowledge of pain management according to the general characteristics of pain in terms of the nurses age(p=.001), position (p=.016). years of experiences(p=.002), experience of cancer pain education(p= .001). Conclusion: The also showed that nurses working at cancer ward lack knowledge. It is important to provide intensive education to nurses about cancer pain management.

The purpose of this research is to obtain the characteristics of strain and stress in the vacuum pressure vessel. The vacuum pressure vessel is used to many of industrial devices and cooling tower system. The vessel is under the vacuum pressure in this research, and we analyzed the stress on the vessel surface. As the experimental set up, we introduced the Static Strain Measurement(UCAM 70A, Kyowa) system. The environmental condition of vessel is reserved under vacuum pressure 50mmHg, and the vacuum pressure was made by a ejector pump system.
