On the basis of a theoretical tenet that voluntary sports commitment is a result of participation motivation both inherent in and extrinsic to the participant, a survey research was conducted with 664 university students sampled from six major universities located in the metropolitan Seoul area. It was theorized that the intrinic motivation for sports commitment is intimately associated with the relative degree of sport socialization which is postulated to be highly dependent upon personal attributes (e.g., sex, sport aptitude, interest, attitude, etc.) as well as upon influences from parents, peers, and teachers during the maturing ages, i.e., elementary and secondary school ages. A self-report sports commitment questionnaire along with a sport socialization scale assessed 1) the present levels of sports commitment of respondents and 2) the degrees of sport socialization as well as socializing factors including personal attributes and influences from significant others. Data analysis(using ANOVA, multiple regression analysis, etc.) revealed that: 1) a very low percentage of respondents practices sports and exercises; 2) even the sport-committed group is engaged mostly in a limited kind of sports learned at the schools, instead of such life-time oriented individual and dual sports as bowling, badminton and jogging, with the frequency and duration being low and short; 3) the main reasons for participating in sports are such extrinsic factors as improvement of health and weight control, rather than pursuit of fun, enjoyment, achievement and win; 4) in contrast, the main reasons for not participating in sports are lack of interest, concern, and skill as well as lack of time and facilities; 5) the sports commitment is significantly influenced by the degree of sport socialization which, in turn, is determined, to a great degree, by such socializing factors as personal interest, attitude, sex, birth place, and influences from significant others. In order to promote mass sports, thus, these results, taken together, suggested a need for more emphasis on school physical education directed toward enhancing the awareness, interest, and attitude toward sports along with the provision of space and facilities for mass sports from the governmental standpoint.

B5-hydroxytryptamine _3수용체(5-HT_3) 길항제와 dexamethasone의 동시투여가 cis-platin에 의한 급성 구토를 막는데 가장 효과적이다. 그러나 현재까지 가장 적절한 정주dexamethasone의 용량이 알려져 있지 않았다. 이에 dexamethasone의 4가지 다른 용량을 투여하여 그 효과를 비교하였다. 환자는 임의 추출되어 cis-platin 투여 45분전에 15분 동안 정주로 각각 dexamethasone 5, 10, 15, 20 mg을 투여 받았다. cis-platin 투여 30분전에는 ondansetron 8 mg이 부가하여 정주 되었다. 1999년 3월부터 2000년 2월까지 54명의 환자가 연구에 등록되어졌고 53명의 환자가 연구 대상으로 실험에 4군 (dexamethasone 5 mg 13명, 10 mg 14명, 15 mg 13명, 20 mg 13명)으로 나뉘어 평가 되어졌다. 급성구토와 구역질의 완전한 예방은 dexamethasone 5 mg을 투여 받은 환자에서 각각 69.2%, 60.9%, dexamethasone 10 mg을 투여 환자에서 69.1%, 61%, dexamethasone 15 mg 투여 환자에서 78.5%, 66.9%, dexamethasone 20 mg을 투여 환자에서 83.2%, 71.0%로 나타났다. 구토로부터 완전한 예방은 dexamethasone 20 mg을 투여 환자에서 5, 10 mg을 투여 환자와 비교하여 높았고, dexamethasone 15 mg을 투여 군에 비교하여서는 약간 우수한 효과만 있었다. 구역질으로부터의 완전한 예방도 월등한 것은 아닐지라도 20 mg을 받은 환자에서 높았다. 항 구토 치료는 특별한 불편 없이 조절되었고, 부작용의 발생에서 4가지그룹간에는 커다란 차이가 발견되지 않았다. Dexamethasone의 20 mg 정주양이 cis-platin으로 인한 급성구토를 예방하는데 가장 효과적인 예방량으로 사료되어진다. Background and objective: A 5-hydroxytryptamine _3(5-HT_3) receptor antagonist plus dexamethasone is the most efficacious antiemetic prophylactic treatment for the prevention of cis-platin induced acute emesis, but the optimal intraveous (Ⅳ) dose of dexamethasone is unknown. This prompted us to perform a randomized, double-blind, dose-finding study that compared four different doses of dexamethasone. Materials and Methods: Patients were randomized to receive dexamethasone, either 5, 10, 15, 20 mg, administered by 15-minute Ⅳ infusion 45 minutes before cis-platin. Ondansetron 8 mg was added to dexamethasone and was administered Ⅳ 30 minutes before cis-platin. From March 1999 to February 2000, 54 patients were enrolled onto the study and 53 were assessable according to the intention-to-treat principle (13 patients received 5 mg; 14 patients, 10 mg; 13 patients, 15 mg and 13 patients, 20 mg of dexamethasone). Results: Complete protection from acute vomiting and nausea was achieved by 69.2% and 60.9% of patients, respectively, who received 5 mg of dexamethasone, by 69.1% and 61.0% of those who received 10 mg, by 78.5% and 66.9% of those who received 15 mg, and by 83.2% and 71.0% of those who received 20 mg of dexamethasone. Complete protection from vomiting was significantly superior in patients who received 20 mg compared with those who received 5 and 10 mg of dexamethasone (P<05) and was superior, but not significantly, compared with those who received 15mg. Complete protection from nausea was superior, but not significantly, in patients who received 20 mg of dekamethasone. Multifactorial analysis confirmed these results. Antiemetic treatment was well tolerated, and no significant difference was found among the four groups in the incidence of adverse events. Conclusion: A 20mg single Ⅳ dose of dexamethasone should be considered the most efficacious prophylactic dose for the prevention of ois-platin induced acute amesis in treatment of cancer.

Since the residential load is an AC load and the output of solar cell is a DC power, the photovoltaic system needs the DC/AC converter to utilize solar cell. In case of driving to interact with utility line, in order to operate at unity power factor, converter must provide the sinusoidal wave current and voltage with same phase of utility line. Since output of solar cell is greatly fluctuated by insolation, it is necessary that the operation of solar cell output in the range of the vicinity of maximum power point. In this paper, DC/AC converter is three phase PWM converter with smoothing reactor. And then, feedforward control used to obtain a superior characteristic for current control and digital PLL circuit used to detect the phase of utility line.

Abstract - Recently, the IP multicast providing point-to-multpoint delivery has received wide concerns due to the ever increasing applications based on it, such as video on demand, IP broadcasting service, and so on. However, most of the exiting multicast protocols have a scalability problem in which the network performance degrades as the increase of the network size. Among the existing protocols, the Protocol Independent Multicast(PIM) protocol has been known as one the effective protocols that handles the scalability problem. Especially, the PIM-SM is more suitable for the realistic situation of the current Internet. The purpose of this paper is to examine the effect of this threshold value on the network performance in respect of the packet loss for a variety of network topologies.
