Objective : Modern acupuncture research often utilizes the methodology of animal experiment where animal acupoints(AA) are stimulated and the results observed. There hasn't been any consensus on the AA locations yet, but it is integral for the locations to be defined in detail for any animal experiment. Methods : The review of 24 original articles published in the Journal of Korean Acupuncture and Moxibustion Society for recent one year which utilized animal experiment methodology revealed that AA are located primarily by the method of transposition from human acupoints. Only a few of those AA were defined in detail. ST-36, CV-12, GB-34, BL-23 were among the most frequently used AA. Results & Conculsion : Transpositional Ⅲ acupoint system of mouse is proposed, which includes 3 points of LU meridian, 4 of LI, 10 of ST, 8 of SP, 3 of HT, 4 of SI, 26 of BL, 2 of KI, 4 of PC, 3 of TE, I1 of GB, 6 of LR, 8 of CV and 19 of GV.

Purpose: This study was performed to evaluate DITI (Digital Infrared Thermographic Imaging)'s potential for diagnosis and indicator of abdominal cold hypersensitivity treatment from the clinical case study. Methods: The patient was a 35-year-old woman who was suffered by general coldness, sweating and general pain. The patient was treated by Herb medicine, Acupuncture treatment, Moxa treatment and Physical Treatment. The progress of symptoms was evaluated by checking the change of VAS, and inspecting the DITI. We studied the statistical significance from the difference of DITI results before and after treatment by paired T-test using SPSS windows (version 12.0). Results: The general coldness, sweating and general pain of this patient have declined, especially the abdominal coldness improvement showing. As a results, the temperature of four abdominal sites(GV4,6,12,17) after treatment were statistically higher than those before treatment. With comparison of Indang, DITI difference of abdominal sites before and after treatment were statistically significant from paired T-tests. Conclusion: The results suggest that DITI can be used for the diagnosis and assessment of abdominal cold hypersensitivity treatment.

Objective : The purpose of this study is to establish a category for acupuncture therapy by appropriate etiological analysis and differenciation of edema. Methods : We arrange Huang Di Nei Jing and thirty four kinds of literature about edema. Results : 1. The cause of Edema is functional disorder of lung, spleen, kidney, bladder and tri-energizer by six kinds of natural factors, internal injury and loss of nutritions. 2. Edema compartmentalize into the water of five zang organs, several kinds of edema(e,g. 5, 10, 12, 24) and yang & yin edema. 3. An ultimate cause of edema pathogenesis is the disturbance of Qi function in kidney. 4. In view of the results so far achived,'GV26(水淸)' is a vitally important acupoint in acupuncture treatment of edema.'GV26(水淸)' and 'CV9(水分)' are very useful acupoints in moxibustion. 5. In the acupuncture and moxibustion treatment of yang edema, we can use acupoints as like 'GV26(水溝)', 'S36(足三里)', 'B20(脾兪)' and 'SP9(陰陵泉)' by purgation and reduction for expelling wind, reducing fever and eliminating dampness. In an instance of yin edema, we can use acupoints as like 'CV9(水分)' 'S36(足三里)', 'CV6(氣海)', 'B20(脾兪)', 'B23(腎兪)' and 'K3(太谿)' by reinforcement for tonifying spleen yang-middle energizer-, qi-transmission and water promoting.

The objective of this study is to determine the developmental competence of in vitro matured bovine oocytes after intracytoplasmic sperm injection(ICSI) with frozen-thawed epididymal spermatozoa. The ovaries were obtained from slaughtered Korean native cows. Oocytes matured in vitro for 24 hrs were fertilized by ICSI with frozen-thawed epididymal spermatozoa. After ICSI, a group of oocytes was activated with 7% ethanol fur 5 min, and the other group was not activated. The oocytes were cultured in TCM-199 medium containing hormones and 10% FCS for 24~30 hrs in a incubator with 5% $CO_2$ in air at 38.5$^{\circ}C$. The percentage of oocytes reaching M II after 24 hrs and 30 hrs of incubation were significantly higher(p<0.05) after culture with TCM-199 media(80.0% and 88.3%) than M I(8.3% and 6.7%). The rate of cleavaged embryos to blastocyst obtained by ICSI treated activation oocytes was significantly higher(p<0.05) than that of nonactivation oocytes(22/46, 47.8% vs 10/39, 25.6%). The rates of embryos development to blastocyst obtained by ICSI treated sperm of flesh, epididymal and frozen-thawed epididymal were 24/45(53.3%), 15/40(37.5%), 11/43(25.6%), respectively and these values of fresh sperm injection were higher than frozen-thawed epididymal sperm. We also concluded that embryos can be produced with ICSI of in vitro matured oocytes by ICSI using frozen-thawed epididymal semen.

연구목적: 본 연구에서는 생쥐 Dazla 유전자의 난소내 발현 위치를 확인하고, 배아의 발달에 따른 Dazla 유전자의 발현 양상을 관찰하고자 하였다. 연구재료 및 방법: 임신 제 7일, 10일, 11일, 14일의 태자 (각각 n=9)와 생후 27일된 암컷 미성숙 생쥐 (n=32), 8주령의 암컷 성숙 생쥐 (n=9)로 부터 난자, 과립막세포, 난소 조직을 획득하였으며, 9주령의 수컷 성숙 생쥐 (n=3)로부터 고환 조직을 획득하였다. 각각의 획득된 조직과 세포에서 Dazla mRNA의 발현 여부를 RT-PCR, in situ hybridization (ISH) 방법 등으로 확인하였다. 성선자극호르몬을 투여하지 않은 미성숙 및 성숙 생쥐에서 획득한 미성숙 난자 (GV)와 PMSG와 hCG를 투여한 미성숙 및 성숙 생쥐에서 획득한 성숙 난자 (MII)에서 RT-PCR로 Dazla 유전자의 발현 여부를 확인하였다. 미성숙 및 성숙 생쥐의 난소 조직과 성숙 생쥐의 고환 조직에서 RT-PCR 및 ISH 방법으로 Dazla 유전자의 발현 여부를 확인하였다. 결 과: 난소의 과립막세포에서는 미성숙 및 성숙 생쥐, PMSG와 hCG 투여 여부 등과 상관없이 모두 Dazla 유전자의 발현은 음성으로 판정되었다. PMSG 및 hCG를 투여하지 않은 난소에서 획득한 미성숙난자 (germinal vesicle, GV) 또는 PMSG 및 hCG 투여 후 채취한 성숙 난자 (metaphase II, MII) 모두 Dazla 유전자가 발현되었다. Dazla 유전자의 발현은 수정 직후 (2PN) 음성으로 전환되었으며, 착상 직전의 배반포 시기까지 유전자 발현이 음성으로 지속되었다. Dazla 유전자는 임신 제 7일 (PCD 7), 10일 (PCD 10), 11일 (PCD 11)의 태자에서도 유전자 발현이 계속 음성으로 관찰되었으나, 성 분화가 일어나기 시작하는 임신 제 $12{\sim}14$일 (PCD $12{\sim}14$)의 태자에서 유전자 발현이 다시 관찰되었다. 결 론: Dazla 유전자는 난소 내 난자에서만 특이적으로 발현하는 난자 특이 유전자 (oocyte specific factor)로서 Dazla 유전자가 난소 내 난포 생성과 관련성이 있음을 제시하고 있다. 향후 조기 폐경 환자에서의 연관성 등을 확인한다면 임상적으로 유용한 지표가 될 수 있을 것으로 사료된다.

This study was carried out to reduce the lateral vibration of high-speed electric multiple units. In the study, the high-speed electric multiple unit prototype (HEMU-430X) has a high lateral vibration at low equivalent conicity regardless of the wheel profiles (XP55, GV40, S1002). As wheel wear progresses and the equivalent conicity increases, the lateral vibration tends to decrease. The reason is that a combination of the suspension characteristics causes the body and bogie to resonate at a frequency of 1.4 Hz when the equivalent conicity is low, resulting in body hunting. An investigation of the lateral vibration of overseas high-speed trains showed that a decrease in the hydraulic stiffness of the yaw damper could improve the vibration. The series stiffness of the yaw damper is a combination of the hydraulic stiffness and elastic joint. In this study, an attempt was made to improve the lateral vibration by lowering the stiffness of the elastic joint. The series stiffness of the adjusted yaw damper was approximately 60% compared to the original one. The on track test results showed improvement in the lateral vibration for both running directions. The vibration reduction method of this study can be used for EMU-250 and EMU-320 in future commercial operations.

Morphological evolution and growth mechanism at the solid/liquid interface during solidification were investigated in the Ni-base superalloy GTD111M by directional soldification and quenching(DSQ) technique. The experiments were conducted by changing solidification rate(V) and thermal gradient(G) which are major solidification process variables. High thermal gradient condition could be obtained by increasing the furnace temperature and closely attaching the heating and cooling zones in the Bridgeman type furnace. The dendritic/equiaxed transition was found in the G/V value lower than $0.05$\times$10{^3}^{\circ}C$s/$\textrm{mm}^2$, and the planar interface of the MC-${\gamma}$ eutectic was found under $17 $\times$ 10{^3}^{\circ}C$ s/$\textrm{mm}^2$. It was confirmed that the dendrite spacing depended on the cooling rate(GV), and the primary spacing was affected by the thermal gradient more than solidification rate. The dendrite lengths were decreased as increasing the thermal graditne, and the dendrite tip temperature was close to the liquidus temperature at $50 \mu\textrm{m}$/s.
