Handover Ranging Power Adjustment Using Uplink Channel Information in IEEE 802.16e/m Ji-Su Kim, and Jae-Hyun Kim, ETRI Journal, vol.32, no.5, Oct. 2010, pp.823-826.

This letter proposes a handover ranging power adjustment scheme to improve handover performance. Incorrect ranging power can degrade handover performance due to the increased handover latency; therefore, the proposed scheme exploits the uplink channel information to adjust the uplink handover ranging power. Simulation results demonstrate that the proposed scheme reduces call outage probability by 33% compared to that of the conventional scheme. It also improves the number of users who satisfy the system requirements for handover interruption time.

집성재 단면구성에 따른 휨성능 평가

이전제,김광모,한재수,김재건 한국목재공학회 2003 목재공학 Vol.31 No.5

본 연구에서는 몇 가지 새로운 집성재 단면구성 방법을 제안하고, 국산 낙엽송과 합판으로 제조된 집성재의 휨시험을 통해 단면 구성에 따른 집성재의 침성능을 평가 비교하였다. 수평적층(BH), 수직적층(BH), 수직으로 합판보강된 수직적층(BVV)과 수평으로 합판보강된 수직적층(BVH)의 총 네가지 형태의 단면구성 방법에 대하여 실험을 실시하였다. 파괴모드를 관찰하고, 실험을 통해 얻어진 하중-변형 곡선으로부터 MOR 및 MOE를 계산하여 이를 바탕으로 각 단면구성 방법의 휨성능 개선효과를 비교하였다. MOR의 경우에는 결함의 분산으로 인해 수직적층에서 수평적층에 비해 23% 정도의 개선효과를 얻을 수 있었으나, MOE의 경우에는 거의 유사한 값을 나타내었다. 수평으로 합판보강된 경우에는 상대적으로 휨성능이 약한 합판이 사용됨에 따라 MOE가 15% 정도 감소하였으나, 수직으로 합판보강된 경우에는 합판이 사용되었음에도 불구하고 MOE의 감소 없이 MOR이 개선되는 효과를 나타내었는데 이는 전단보강의 효과로 생각되며 이러한 효과를 파괴모드의 관찰을 통해서도 확인하였다. 이상의 결과로부터 집성보의 단면 구성시 라미나의 적절한 배치 및 전단보강 등을 통하여 전체적인 휨성능을 향상시킬 수 있음을 확인하였다. In this paper, bending capacities of glulams with different configurations of cross-section were evaluated. These configurations included horizontal(BH), vertical(BVN), vertical with vertical plywood(BVV) and vertical combination of lamination with horizontal plywood(BVH). Full-scale bending tests were performed to investigate the effect of different section configurations on bending strength(MOR) and stiffness(MOE) of glulam. Compared with type BH, MOR of glulam with type BVN configuration was improved about 23%, which was considered to be caused by defect dispersion effect, while MOE of glulams with these two types of configurations were similar. Because MOE of plywood is generally smaller than that of solid wood laminar, MOE of type BVH glulam decreased about 15%, but in the case of type BVV glulam, MOE was improved without any reduction of MOE. The reason of this result could be undersood in the view of shear-reinforcement effect, which was verified from analysis of fracture mode. From the results of this study, it was concluded that bending capacity of glulam could be improved by proper section design, such as laminar arrangement and shear reinforcement.

Objectives : The purpose of this study is to report a 67-year-old male patient with Herpes zoster(caseⅠ) and a 38-year-old female patient with Herpes zoster(caseⅡ), whose symptoms were relieved after Korean medicine treatment alone. Methods : Both patients took Yeonryeonggobondan and Pyungwee-san daily. Everytime they came to the hospital, they received acupuncture treatment, Hwidam's Su-Gi therapy and External Gigong Therapy. Acupuncture was applied by gall bladder seunggyeok(膽勝格, GB-), spleen jeonggyeok(脾正格, SP+), large intestine seunggyeok(大腸勝格, LI-) of Saam's Acupuncture Method. Hwidam's Su-Gi therapy was applied on neck. External Gigong Therapy was applied on skin lesion area. the patients' symptoms were evaluated with photographs and VAS. Results : The results were as follows: 1. In the case of a 67-year-old male patient, it took 14 days to recover the skin lesions and to reduce the pain after treatment started. And he visited 13 times during that period. 2. In the case of a 38-year-old female patient, it took 23 days to recover the skin lesions to reduce and the pain after treatment started. And she visited 10 times during that period. 3. Intensive treatment early in treating herpes zoster helped to shorten the treatment period. 4. Taking Yeonryeonggobondan and Pyungwee-san and receiving acupuncture treatment(SP+) can help to improve immunity and recover skin lesions in herpes zoster diagnosed with spleen deficiency with dampness encumbrance(脾虛濕困) and blood stasis due to qi stagnation(氣滯血瘀). 5. The combination of acupuncture treatment(GB-) and External Gigong Therapy was effective in controlling pain. 6. External Gigong Therapy is considered to be effective for the recovery of the skin as well as the pain of the herpes zoster. Conclusions : Korean medicine treatment alone has a great effect on the above two patients with herpes zoster. I hope the active research about Korean medicine treatment will be done not only for herpes zoster but also for various intractable pain diseases.

Objective In order to study the effects of bee venom(BV) on the pain, edema, and acute inflammatory reactant of rheumatoid arthritis(RA) patients. Methods Patients with RA who met the ACR(American College of Rheumatology) 1987 revised criteria for the diagnosis of RA were treated with the BV therapy twice a week for 3 months. Tender Joint counts, swollen joint counts, Visual analog scale(VAS), morning stiffness, ESR. C-reactive protein(CRP) were analyzed before and after BV therapy. Results The results as follows. 1. Tender joint counts in patients after BV therapy were significantly lower than those before BV therapy(9.0±7.9 vs 15± 11.4, p=0.002). 2. Swollen joint counts of the patients after BV therapy were significantly lower than those before BV therapy(50±61 vs 15±23, p=0.001). 3. VAS in patients after BV therapy was significantly lower than those before BV therapy(608± 17.6 vs 380± 159, p=0.000). 4. Duration of morning stiffness in patients after BV therapy was significantly reduced compared with that before BV therapy(119.1± 112.6 min vs 59.0±89.7 min, p=0.009). 5. ESR and CRP were not significantly changed before and after BV therapy, suggesting BV itself could make inflammatory reaction as well as therapeutic effect. Conclusions BV therapy improved tender joint counts, swollen joint counts and duration of morning stiffness in this study, and further study is needed on long-term effect of BV therapy.

Objective: To evaluate the effects of bee venom acupuncture(BVA) on the rehabilitation and quality of life in rheumatoid arthritis(RA) patients Methods: Patients with RA were treated with the BVA therapy twice a week for 3 months. Tender joint counts, swollen joint counts, morning stiffness, Erythrocyte Sedimentation Rate(ESR), C-reactive protein(CRP), patient global assessment, physician global assessment, Korean health assessment questionnaire(KHAQ) were estimated and analyzed before and after BVA therapy. Results: Tender joint counts, swollen joint counts, morning stiffness showed significant decrease after BVA therapy. But, as acute inflammatory reactants, ESR showed no significant difference and CRP showed significant increase after BVA therapy. Patient global assessment physician global assessment, and KHAQ index showed significant improvement after BVA therapy. Conclusions: BVA therapy can improve rehabilitation and health-related quality of life RA patients as well as clinical symptom and signs. Further study is required in more population with large scale including acute inflammatory reaction of BVA therapy.

This study is to investigate the influence of containers and packaging of women's cosmetics on the purchasing preferences of view. The subject of this study was the consumers of women's cosmetics from their 30s to 40s. And the questionnaire was conducted by 195 consumers who dropped into beauty counters to buy their cosmetics. According to this study, we found that containers and packaging is an effective factor on purchasing of women's cosmetics. In general, most consumers prefer to practical and useful containers and packaging but the 30s consumers tend to be more influenced by luxury and expensive containers and packaging. And there was a little difference in purchasing preferences by their academic background. Key Words : Purchasing Preferences, Package Design, Women's Cosmetics, Women Consumers, Containers and Packaging
