This study was designed to evaluate the analgesic effect of bee venom (BV) Acupuncture into different treatment points, Chok-samni (ST36) and blank loci of the gluteal muscle and back. We investigated the changes in formalin-induced pain behavior according to the pretreatment with different concentrations of BV, thirty minutes before the formalin injection. The results were summarized as follows: 1. The formalin-induced pain behavior was suppressed by pretreatment with BV into Chok-samni (ST36) in a dose dependent manner. During the early phase, 0.08mg/kg of BV showed a statistically significant suppression in the formalin-induced pain behavior. Moreover, 0.008mg/kg, 0.016mg/kg, and 0.08mg/kg of BV, except 0.0016mh/kg of BV, had significant suppresive effects on the formalin-induced pain behavior during the late phase. Therefore, these data indicated that the suppressive effect of BV acupuncture on the formalin-induced pain behavior was stronger in the late phase rather than the early phase 2. In order to investigate the analgesic effect of BV acupuncture into different treatment points, the experimental animals were divided into three groups: Chok-samni (ST36) group, gluteal group and back group. In the Chok-samni (ST36) group, the formalin-induced pain behavior during all the phases was significantly reduced as compared with that of the back group. However, as compared with that of the gluteal group, the formalin-induced pain behavior in the Chok-samni (ST36) group was decreased only in the late phase, not in the early phase. The formalin-induced pain behavior in the gluteal group was significantly reduced as compared with that of the back group in the late phase, not in the early phase. We suggested that the analgesic effect of BV acupuncture into Chok-samni (ST36) was most effective among Chok-samni (ST36), gluteal, and the back groups in formalin-induced pain behavior.

Objective : This study was done to observe the effects on the thermal changes of herbal acupuncture. There were remarkable local thermal changes between pre and post herbal acupuncture therapy on D.I.T.I. or not. If there are those, we examine how long changes of those were maintained, what is the adequate interval on herbal acupuncture therapy. Methods : D.I.T.I, was used to study the local thermal changes in herbal acupuncture therapy. Determination of this analysis periods are pre and post-therapy(1hour, 1day, 7days later). The study group was divided into six groups that are NS group(No.=20), CF group(No.=22), BU group(No.=23), BUM group(No.=19), HP group(No.=20) and BV group(No.=l9). The herbal acupuncture was injected by 0.2ml divided into 0.05ml at the Fengmen(風門: B12), Feishu(肺兪: B13), Fufen(附分: B41), Pohu(魄戶: B42) 4 points. Then, we checked the thermal changes of their point after performing. Results : The following results were obtained ; 1. In CF groups, significant dermatothermal difference between pre and post therapy was not checked, In BU group that continued until post-therapy 1day, in HP group until 1hour, in BV group until 2days. In BUM, HP and BV group, Most dermatothermal difference was checked at post-therapy 1hour, in BU group at post-therapy 1day. 2. At post-therapy 1 hour, significant dermatothermal different between pre and post therapy was checked among BU group, BUM group, HP group and BV group. At post-therapy 1day and 2days, checked among BU group, BUM group and BV group. At post-therapy 7days, not checked among all groups. The group that highest dermatothermal difference were checked is BV group.

동영상 압축에 관한 국제 표준화 기구인 JCT-VC (Joint Collaborative Team on Video Coding) 에서는 High Efficiency Video Coding (HEVC)의 확장 표준으로 스크린 콘텐츠 영상의 부호화 기술을 위한 HEVC Screen Content Coding(HEVC SCC)표준을 제정하였다. 현재까지 개발된 HEVC SCC 기술들 중 가장 높은 부호화 성능을 보이는 화면 내 블록 카피(IBC, Intra Block Copy)기술은 현재 프레임 내에서 복원된 블록들 중 현재 블록과 가장 유사한 블록을 예측하는 과정이다. IBC에서는 전송되는 블록 벡터의 데이터양을 줄이기 위해 예측 블록 벡터 값과 그 차이 값을 부호화 한다. 본 논문에서는 HEVC SCC 참조 소프트웨어인 SCM-2.0과 SCM-4.0을 이용하여 IBC의 블록 벡터 예측 과정에 대해 분석하였다. 또한 분석한 내용을 바탕으로 HEVC SCC IBC의 IBC의 예측 성능 향상을 위해 예측 블록 벡터(BVP, Block Vector Predictor) 후보 선정 과정에서 기존의 공간적 BVP 후보 외에 인접한 BV에 대한 탐색 과정을 추가하여 개선된 BVP 후보 선정 방법을 제안한다. 제안 방법의 실험 결과는 부호화 속도 저하 없이 최소 0.2%부터 최대 1%의 BD-rate 감소를 보인다.

According to the expansion of lifespan, neuronal disorder based on inflammation has been social problem. Therefore, we isolated shikonin from Lithospermum erythrorhizon and evaluated anti-inflammatory effects of shikonin in lipopolysaccharide (LSP)-stimulated BV2 microglial cells. Shikonin dose-dependently inhibits the expression of the proinflammatory mediators, nitric oxide (NO), prostaglandin $E_2$ ($PGE_2$), and tumor necrosis factor-${\kappa}B$ (TNF-${\alpha}$) as well as their main regulatory genes and products such as inducible NO synthase (iNOS), cyclooxygenase-2 (COX-2), and TNF-${\alpha}$ in LPS-stimulated BV2 microglial cells. Additionally, shikonin suppressed the LPS-induced DNA-binding activity of nuclear factor-${\kappa}B$ (NF-${\kappa}B$) to regulate the key regulatory genes of the proinflammatory mediators, such as iNOS, COX-2, and TNF-${\alpha}$, accompanied with downregulation of reactive oxygen species (ROS) generation. The results indicate that shikonin may downregulate the expression of proinflammatory genes involved in the synthesis of NO, $PGE_2$, and TNF-${\alpha}$ in LPS-treated BV2 microglial cells by suppressing ROS and NF-${\kappa}B$. Taken together, our results revealed that shikonin exerts downregulation of proinflammatory mediators by interference the ROS and NF-${\kappa}B$ signaling pathway.

This study was designed to evaluate the analgesic effect of bee venom (BV) Acupuncture into different treatment points, Chok-samni (ST36) and blank loci of the gluteal muscle and back. We investigated neuronal activity in the spinal cord using the Fos immunohistochemical technique according to the pretreatment with different concentrations of BV, thirty minutes before the formalin injection. The results were summarized as follows: 1. The number of Fos-like immunoreactive (Fos-LI) neurons in L2 segment of the saline-formalin treated group was significantly increased in NECK and VENT of the spinal cord as compared with that of the room control group. However, there was no significant change in the number of the Fos-LI neurons in L2 segment of the BV-formalin treated group as compared with that of the room control group. 2. The number of Fos-LI neurons in L3-5 segment of the saline-formalin group was significantly increased in all the regions of 142 the spinal cord as compared with that of the room control group. However, the Fos-LI neurons in L3-5 segment of the BV-formalin treated group was dramatically decreased in all the regions of the spinal cord as compared with that of the saline-formalin group. Therefore, these results indicated that the BV acupuncture suppressed the nociceptive neuronal activities in L3-5 of the spinal cord induced by formalin injection. 3. There was a strong positive correlation between the formalin-induced pain behavior and the number of the Fos-LI neurons in L3-5 segment.

Objectives : This study was designed to compare the effects on Korean Western Ontario and McMaster Universities Osteoarthritis Index(KWOMAC), 36-ltems Short-Form Health Survey(SF-36), Visual Analog Scale(VAS) and Nine Point Scale between 'Intramuscular Bee Venom Herbal Acupuncture' and 'Intracutaneous Bee Venom Herbal Acupuncture' in knee osteoarthritis patients for 4weeks. Methods : All the voluntary subject were diagnosed as knee osteoarthritis. Patients were randomly assigned either to two groups : Intramuscular bee venom herbal acupuncture treatment group(IM-BV group) or Intracutaneous bee venom herbal acupuncture treatment group(IC-BV group). The IM-BV group received bee venom herbal acupuncture intramuscularly on muscles closest to the pathologic site on ultrasonography. The IC-BV group received bee venom herbal acupuncture intracutaneously on $LE_{110}$, $LE_{201}$, $ST_{35}$, $ST_{36}$ and $LR_8$. Bee venom herbal acupuncture was applied twice a week for 4 weeks by an oriental medical doctor at Kyung-hee Oriental Medical Hospital. Both groups were checked of pathologic site by ultrasonography before treatment and follow up after four-week treatment. The patients were assessed by KWOMAC and SF-36 before and after four-week treatment. The changes in patients' pain was measured by VAS before treatment and after one-, two-, three- and four-week treatment. The patients' overall treatment outcome assesment was measured by Nine Point Scale after four-week treatment. Results : The results were as follows ; 1. The IM-BV group showed significant improvement on total, pain, stiffness and physical function in KWOMAC, and the IC-BV group showed significant improvement on total and physical function in KWOMAC after 4weeks compared to the pre-treatment. In KWOMAC, the IM-BV group showed more improvement on average compared to the IC-BV group, but there were no significant difference between two groups. 2. The IM-BV group showed significant improvement on VAS after one-week treatment. The IC-BV group showed significant improvement on VAS after two-week treatment. But there were no significant difference between two groups. 3. The IM-BV group showed significant improvement on physical functioning(PF) and bodily pain(BP) in SF-36, and the IC-BV group showed significant improvement on vitality(VT) and bodily pain(BP) in SF-36 after 4weeks compared to the pre-treatment. But there were no significant difference between two groups. 4. 88.2% of IM-BV group and 93.3% of IC-BV group graded their improvement as 'Fair' or better on Nine Point Scale. But there were no significant difference between two groups. Conclusions : This study suggests that in the treatment of knee osteoarthtitis patients, effects of 'Intramuscular Bee Venom Herbal Acupuncture' were not different from 'Intracutaneous Bee Venom Herbal Acupuncture' statistically. But both treatment showed effects on pain and physical function in knee osteoarthtitis patients.
