Adaptive Transmission Scheme for Mixed Multicast and Unicast Traffic in Cellular Systems
Seon Yeob Baek,Young-Jun Hong,Sung, D.K. IEEE 2009 IEEE Transactions on Vehicular Technology VT Vol.58 No.6
<P>Wireless communication systems have been developed to support users' various requirements. Multicast and unicast transmission schemes are proposed for various types of services. The multicast transmission is known as an efficient method for group-data transmission. The data rate for multicast transmission depends on the instantaneous worst channel user. On the other hand, unicast transmission exploits wireless channel variation and achieves a multiuser diversity gain. In this paper, we evaluate and compare the system performance of multicast and unicast transmission schemes in terms of system capacity, worst average channel user's capacity, and outage probability for varying cell environments. We also propose a novel hybrid scheduling scheme for mixed multicast and unicast traffic services and compare the proposed scheme with the conventional scheme.</P>

Objective : This study is designed to find out the effects of Oak-mushroom Herbal acupuncture on osteoarthritis in knee joint. Methods : We investigated 33 cases of patients with osteoarthritis in knee joint that are visited in Hospital of Dong-Seo oriental medicine. We evaluated knee joint function that before and after its treatment by Lysholm score and satisfaction of treatment by Baumgaertner nine point scale and visual analog scale. Results : These results showed that female patients are 26 cases and these are more 19 cases than male patients. On the age of patients, above 61 are mainly distributed as 17 cases. According to Ahlaback's grading system, grade Ⅲ are more than others as 11 cases. We estimated effects of Oak-mushroom Herbal-acupuncture by Lysholm score, those results showed that the mean of Lysholm score before treatment is 51.42, and after treatment is 76.55. That showed statistically meaningful increase. In evaluating of satisfaction, excellent are 11 cases and good are 15 cases. The percentage of above good is 78.8%. Conclusion : According to the results, Oak-mushroom Herbal-acupuncture may be effects on the increase of knee joint function and the decrease of pain in osteoarthritis in knee joint.

Objective : This study has been designed and performed to identify the effect on insomnia patients according to the injection of herbal medicine induced from the Hominis placenta. Methods : Injection on G20(風池), G20(池) in insomnia patients who were admitted in Dong-Seo Oriental Medical Hospital every day for 5days, without western medicine. Results: Total duration of sleeping time showed 0.68 hours of increased. (p<0.005 respectively)

Objective: The purpose of this study is to compare the effects of Dong-si acupuncture therapy and General acupuncture therapy for the patients with acute ankle sprain. Methods : This study has been carried out for 60 cases of ankle sprain patients who have visited Dong-Seo Oriental medical Hospital from May 1, 2002 to September 30, 2002. We have treated 30 cases of them by Dong-si acupuncture therapy and the other 30 cases by General acupuncture therapy. And we have compared those two group. Results : 1. There was no significant difference at the treatment period and the number of treatment times in comparing two groups. 2. The number of treatment times for good effect is that : Dong-si took $1.57{\pm}0.85$ times and General acupuncture therapy took $2.15{\pm}0.96$ times. And we have found that the effect of Dong-si acupuncture therapy is faster than the other.
