CORBA 기반의 분산 오디오/비디오 스트림 서비스 프레임워크의 설계 및 구현
박세철,김종현 동의공업대학 2001 論文集 Vol.27 No.1
This paper presents a design and implementation of a distributed audio/video stream services based on CORBA distributed objects and JMF(Java Media Frameworks). Our design abstracts software components concerning the processing of audio/video streams as distributed objects. And we separate the transmission path of control data and media data for efficient stream transfer. CORBA RPC calls are used as control signals such as connection establishment, call control, device control. But media streams are transmitted by a RTP(Realtime Transport Protocol) directly. Distributed objects are designed by IDL(Interface Definition Language) and implemented using Java and various JMF components. We show a connection establishment and flow control procedure of streams. And we introduce an implementation environments and evaluate a performance.

The purpose of this investigation was to determine the effects of low intensity circuit weight training on physiological variables such as body composition, blood lipid profile and cardiopulmonary function in obese middle school girls. Thirty obese middle school girls (%fat>25%) were divided low intensity into weight training (CWT; n=10), aerobic training(AeT; n=10), and control(CTL; n=10) groups. The participants in the training groups had trained 50 min each day three times pre week for 10 weeks. The results were summarized as the follows: 1.Anthropometry and body composition The height(P<.01) increased significantly. Although the body weight did not show statistically significant changes, it decreased. W/H decreased 11.34%, even though it was not statistically significant increase in LBM. After the 10-week training, there were no significant differences between the CWT and AeT groups in all the variables related to body composition. 2.Blood lipid profile There was a significant decreases in all blood lipid profile. With 10-week training, there was significant difference in TC and TG between the CWT and CTL groups, However, there were no significant difference between the CWT and AeT groups in all the blood lipid profiles. 3.Cardiopulmonary function There was a significant increase in VO2max/kg. There were significant differences between the CWT and CTL groups in VO2max/kg and VO2max/LBM. However there were no significant differences between the CWT and AeT groups. HRrest and Hrmax did not change signicantly. With 10-week training, did not result in significant difference between the groups in all the cardiopulmonary function variables

Injection molding technique is directly related to high quality, low cost which customer needs. Injection molding process is very importantly dealt with the sharp increase of resin consumption and so is studied very actively nowadays. The influential factors to injection molding parts are material melting temperature, mold temperature, injection speed, injection pressure melting temperature are especially important. The boundary and contents of research and development are design injection molding making test specimen of KS rules, manufacturing injection mold, injection varied on mold temperature, injection pressure and melting temperature, mechanical properties injection test specimen, and analysis of test. In this study the specimen for tensile and impact strength tests were made under various cylinder and mold temperatures. Measurements were done to find optimum region of mechanical strength through the tests. And me found that mechanical strength decrease by increasing mold temperature and decreasing melting temperature. Therefore if the molding process is done under the optimum injection characteristics of resin for the final parts can by optimized as well as formability.

슬개골-대퇴골 관절의 합병증은 슬관절 전치환술 후 가장 흔한 합병증 중의 하나로, 이런 합병증을 예방하기 위해 슬관절 전치환술 시 슬개골을 치환할 것인가, 아니면 보존할 것인가에 대하여 아직도 많은 논란이 되고 있다. 1993년 8월부터 200년 8월까지 퇴행성 관절염 및 류마티스 관절염으로 슬개골 치환을 하지 않고 인공슬관절 전치환술을 시행한 환자 중 2년이상 추시가 가능했던 36명, 43례를 연구대상으로 하였다. 전례에서 슬개골의 퇴행성 변화에 관계없이 슬개골 보존술(즉 슬개골을 치환하지 않고 슬개골 성형술만 실시함)을 시행하였으며, 추시 기간은 최단 2년에서 최장 10년으로 평균 54개월이었다. 수술전 슬개골의 방사선 사진으로 정상 슬개골을 A군 (10례), 중등도의 퇴행성 변화를 B군 (20례), 심한 퇴행성 변화를 C군 (13례)으로 분리하여 세군의 슬관절 전방부 동통, 운동범위, 계단 오르기 능력 등의 임상적 소견과 슬개골 경사(patellatilt) 및 외측 슬개골 전위(lateral patella shift)의 두 가지 방사선사학적 소견을 비교 분석하였다. 35명중 퇴행성 관절염이 29명, 류마티스 관절염이 6명였으며, 임상적 분석은 American Knee Society Score(KSS)를 사용하였다. 최종추시시 평균 Knee Society Score (KSS)는 A군 93.1점, B군 92.7점, C군 94.2점이었다. 총 43례중 슬관절 전방부 동통을 호소한 예는 A군 2례, C군 2례로 4례 (9.3%)뿐이었으며, 이들은 보행 시는 동통이 없으나, 쪼그린 자세나 계단을 오르내릴 때 동통을 호소하였다. 세군간의 슬관절 운동범위, 계단 오르기 능력 등의 비교에서는 유의한 차이가 없었으며, 방사선학적 비교에서 외측 슬개골 전위는 유의한 차이가 없었고, 슬개골 경사는 A군과 B군에서는 유의한 차이가 없었으나, C군에서는 유의하게 차이가 있었으므로 술전 슬개골의 퇴행성 변화가 심할수록 슬개골 경사가 증가됨을 알 수 있었다(p=0.01). Patello-femoral problem is one of the common complications in total knee arthroplasty and whether to replace the patella or retain it has long been controversial in order to prevent the complications. 43 cases (35 patients) of total knee arthroplasty with patellar retention performed by single surgeon between August 1993 and August 2000 were reviewed retrospectively. The follow-up period averaged 54 months (range, 24-120months). The whole cases were divided into three groups according to the preoperative radiographs. Group A was normal patella (10 knees), Group B was borderline arthritic patella (20 knees), and Group C was severely deformed patella (13 knees). All of 43 knees, regardless of preoperative radiological degree of arthritis received patelloplasty including removal of osteophytes, subchondral shaving and lateral retinacular release was performed in 20 knees (47%). Each groups was evaluated in terms of the objective criteria of anterior knee pain, range of motion, stair climbing ability, and roentgenographic findings. All 35 patents were diagnosed as osteoarthritis in 29 and rheumatoid arthritis in 6. American Knee Society Score (KSS) was assessed for the clinical analysis and lateral patella shift and patella tilt were assessed for roentgenographic analysis. The mean Knee Society Score at final follow-up was 94 in group A, 93 in group B, and 94 in group C. Mild anterior knee pain was reported in 9.3% (Group A: 2 cases, Group C: 2 cases). patellar tilt was significantly higher in C group (oneway ANOVA test, p=0.01), representing that advanced patello-femoral arthritis caused increased patellar tilt. There was nither significant difference in terms of range of motion, and stair climbing ability nor of patellar shift among all three groups. TKA with patelloplasty, not resurfacing the patella, provided satisfactory results without significant problems regardless of the preoperative degree of patello-femoral arthritis.

The purpose of this study was to investigate the current status of first aids program in the safety education that was a part of the physical education curriculum in middle school. And this study is to supply the fundamental data for efficient safety education. The data was gathered with questionnaires given to 145 physical education teachers in Kangwon Province. Teachers think that the first aids education is essential in middle school curriculum. Taking considerations of the numerous accidents in society. This need will provide a remedy for any emergent situation and enlighten the safety-first-mind to protect against accidents. However, it is difficult to determine that efficient and good quality of first aids education is implemented in middle school. Based on the data, followings are some findings from the result; a) teachers lack experiences with first aids education, b) teachers are not equipped with sufficient theoretical and practical knowledge about first aids, and c) classroom teaching materials for first aids education are not furnished in the school at all. To suggest based on the above conclusions, the information about first aids must be employed in depth during the training period for present teachers along with learning physical education teachers so as to develop the theoretical knowledge and applicable capability about the education. Schools must stock adequate teaching materials for first aids education, and seek for effective and high quality education.

This study was taken their weight and measured eight and measured kinds of physical fitness for the study intended for fourteen weight lifters in Kangwon Physical High School. The measure had been carried for ten days before the game. We have also measured the physical fitness while reducing their weight for two days. We compared the result after the loss in weight with that of before. As a result, we have the conclusion as follow 1. According to the statistics, there was no significant difference in muscular fitness (sit- up, back muscular strength, vertical arm pull test) between the two results. 2. There was no significant difference in leg muscula power (sarjent jump) statistically. 3. There was no significant difference in muscula endurance (handstand push-up, pull squat). 4. Statistically, we had no significant difference in agility (side-step) 5. The appropriate weight for lifters is about two kilograms lower than usual. Two kilograms mean about three percent of his own weight. As mentioned above, we can see that the method, the degree and the period of the loss in weight don't influence the physical strength for weight lifters. Therefore, they need to keep their weight proper all the time within the limit of around two kilo-grams of weight limits.

This study is the research of middle school students' sports participation and the contact into computer lewdness. The followings are conclusions. 1. The positive students participated in sports have much experience in the computer lewdness. The positive students are more sensitive than negative students in sexual behavior. The sexual response after they watch computer lewdness was positive. The positive students were more progressive than negative students in the sexual consciousness. 2. Most of the students in the response of research question have experiences of contact into the computer lewdness, the boys were exposed more than girls. They watched the computer lewdness with their friends but they don't watch it habitually. The realities of computer lewdness are inclined to recognize negatively and extensively by mass communication. 3. Their sexual behaviors when they watched the lewdness were low point below the average, the boys were more positive than girls. In the experience of acquaintance , the girls were more positive than boys. But most of the students had no sexual experience. 4. The sexual response when the students watch the scene of the lewdness was low below the average point, the girl students are negative than boys and some of the boys have the sexual desire. These present state are the common things that they have in the adolescence and they are not only because computer lewdness. Therefore we need many kinds of sex education in order not to have disgust in sex. 5. In the response of sexual consciousness, most of the students are interested in lower than average point. They are conservative and negative. The positive students in sports are more progressive than negative students.
