Objective: This paper aimed to understand influences on EEG conducting acupuncture stimulation, by comparing the changes in the acupoints on the body before and after normal people are treated with acupuncture at PC9 and TE3, which are referred to as Wood points(木穴), and PC5 and TE1, which are referred to as the Metal points(金穴) among the five shu points of Yin pericardium Meridian and Yang Triple Energizer Meridian. Methods: The study was performed on 30 healthy female volunteers in their 20's. EEG was measured for 5 minutes before acupuncture stimulation was conducted on PC9, TE3, PC5 and TE1. During 20 minutes of acupuncture treatment, the same items were continuously measured to find out whether there were any changes in them, and they were measured for 5 minutes after removing the acupuncture needles in order to implement a comparative analysis. Results: Comparision of EEG data before and after the treatment at PC9 shows no significant differences in all wave. Compared with the pre-acupuncture period at TE3, $\delta-\theta$ wave decreased significantly (P<0.05) during the acupuncture stimulation periods. Compared with the pre-acupuncture period at PC5, $\delta-\theta$ wave and high $\alpha$ wave increased significantly (P<0.05) during the acupuncture stimulation periods. And Mid $\beta$ wave and high $\beta$ wave decreased significantly (P<0.05) during the acupuncture periods and the post acupuncture periods. Compared with the Pre-acupuncture period at TE1, $\delta-\theta$ wave, $\theta$ wave and high $\alpha$ wave increased significantly (P<0.05) during the acupuncture stimulation periods. And Low $\beta$ wave decreased significantly (P<0.05) during the acupuncture periods. Conclusion: When acupuncture stimulation was performed on PC9 and TE3, referred to as the "Wood points", brain waves were stabled, while when acupuncture was performed on PC5 and TE1, called the "Metal points", a brain was waked. From the findings of this study, we hypothesize that the wood properties, from which growing starts in all things, are related with fast waves of EEG, and the metal properties, which stabilize and converge in all things, are related with slow waves of EEG.

This study was conducted to evaluate the effects of trinexapac-ethyl (TE) and prohexadione-calcium (PC) on the growth and turf quality of perennial ryegrass (Lolium perenne L.). Treatments were designed as follows; control (non-treatment), TE (TE 0.01 a.i. g·m^-2·100mL^-1), and PC (PC 0.01 a.i. g·m^-2·100mL^-1). Compared with control, turf color index and chlorophyll content of TE and PC treatments were not significantly different. As applied plant growth regulators (PGRs), shoot length in the TE and PC was decreased by 8.9-12.4% and 6.7-13.6%, respectively, and clipping yield by 44.4-45.8% and 40.6-40.9%. When evaluated with the growth of shoot length after applying PGRs, residual days of TE and PC were 43.6 and 37.9 days after treatment of PGRs (DAT) in the 1st experiment (July 29-August 26), respectively, and 38.3 and 39.5 DATs in the 2nd experiment (September 30-October 28). These results indicated that an application of TE or PC decreased shoot length and clipping yield in the perennial ryegrass, and their residual time was about 40±3 DATs. Perennial ryegrass applied with PGRs like TE and PC was not significant seasonal difference, and might be not phytotoxic.

Thermal stability of $Ge_2Sb_2Te_5$ (GST) and $SiO_2$ doped GST (SGST) films for phase change random access memory applications was investigated by observing the change of surface roughness, layer density and composition of both films after isothermal annealing. After both GST and SGST films were annealed at $325^{\circ}C$ for 20 min, root mean square (RMS) surface roughness of GST was increased from 1.9 to 35.9 nm but that of SGST was almost unchanged. Layer density of GST also steeply decreased from 72.48 to 68.98 $g/cm^2$ and composition was largely varied from Ge : Sb : Te = 22.3 : 22.1 : 55.6 to 24.2 : 22.7 : 53.1, while those of SGST were almost unchanged. It was confirmed that the addition of a small amount of $SiO_2$ into GST film restricted the deterioration of physical and chemical properties of GST film, resulting in the better thermal stability after isothermal annealing.

Objective : To develop an integrated curriculum for acupuncture treatment and pain sensitivity practice, and discuss its usefulness. Method : We established an integrated practice program incorporating acupuncture and pain on physiology perspectives, and measured pain sensitivity at Yin (PC6${\sim}$PC4) and Yang (TE5${\sim}$TE9) meridians before and after the acupuncture treatment. Results : The Yang (39.4${\pm}$23.5) and Yin (46.0${\pm}$25.5) meridians have significantly different degrees of pain sensitivity (n=118, p=0.018). Pain sensitivity was significantly decreased after acupuncture treatment at Yang (54.63${\pm}$28.02/ 40.81${\pm}$29.39) and Yin (56.13${\pm}$27.88/ 38.72${\pm}$25.17) meridians (n=16, p<0.001). Discussion and Conclusion : The difference between the Yin and Yang meridians can be materialized in this integrated practice curriculum model. The effectiveness of this integrated class and suggestions for improvement of integrated curricula were discussed.

Objectives : This study is to observe the changes in the expression of neurotransmitters, such as NO, nNOS, and NE, upon the needle insertion to the sea points, which is one of the five transport points. Methods : Needles were inserted into rats, on both left and right sides of all sea points, including the LU5, PC3, HT3, LI11, TE10, SI8, SP9, LR8, KI10, ST36, GB34, and BL40, which are the sea points of five transport points for 12 meridian vessels. After insertion, needles were retained for five minutes. After the retention, blood was drawn via cardiac puncture, and tissues of each point near meridian vessels were extracted to examine the changes in the expression of NO, nNOS and NE. Results : In terms of the effect in NO production, there was a significant decrease only in the LU5 point, whereas there was a significant increase in the TE10 point alone. In terms of the expression of nNOS within tissues, none of the experimental groups showed significant changes based on the results of immunohistochemistry and western blotting. Regarding the formation of norepinephrine within tissues, the HT3, SP9, and KI10 point showed a significant decrease, while the PC3 and LR8 point showed a significant increase. Production of plasma norepinephrine was significantly increased at the TE10, SP9, LR8, GB34, and BL40 point. Conclusions : The effect of needles applied at the sea points of five transport points of 12 meridian vessels on the functions of NO, nNOS, and NE could be observed, and it is considered that the effect of needle stimulation on nervous system disorders could be studied through additional researches based on this one.

Objective: There are currently no disease-modifying medications or definite long-term sustainable interventions for patients with Parkinson's disease (PD), indicating an unmet treatment need. Our goal was to create a long-term sustainable intervention for PD patients that can be used in Korean medicine clinics. Methods: The Meridian Activation Remedy System (MARS) was created to stimulate a patient's 12 meridians and sinew channels using a combination of acupoint stimulation and exercise. The acupoints and motions used in MARS were selected through literature studies and expert advice. The methodologies were refined using observational and case studies. With slow and fast movements, the MARS intervention was intended to activate both slow- and fast-twitch muscle fibers. Intradermal acupuncture and motion that shift the center of gravity were employed to enhance the patient's balance and proprioception. In addition, the intervention included alternating movement exercises to address the complex cognitive decline commonly occurring in PD patients. Results: The following acupoints were chosen for the MARS intervention: bilateral Hegu (LI4), Houxi (SI3), Waiguan (TE5), Neiguan (PC6), Zhongchong (PC9), Yuji (LU10), Zusanli (ST36), Yanglingquan (GB34), Taichong (LR3), Kunlun (BL60), and Taixi (KI3). We also developed actions that can stimulate the body's 12 meridians. Conclusion: We developed the MARS intervention, which combines acupuncture and exercise, to address the unmet therapeutic needs of PD patients. We hope that with additional research, the MARS intervention can be set as an effective therapeutic program for PD patients.

Objectives : The aim of this study was to investigate the characteristic of ryodoraku in the chronic low back pain patients who visited department of oriental rehabilitation medicine. Methods : Subjects were 32 patients who visited department of oriental rehabilitation medicine(<60 years old). The low back pain patients were measured points of twelve meridians by ryodoraku diagnosis and checked the duration of low back pain. We compared the mean ryodoraku and the percentage of each points beyond the physiological range. Results : The score of H1(LU9), H2(PC7), H3(HT7), H5(TE4) and F5(GB40) had statistical differences compared with mean ryodoraku. And the correlation between duration of pain and mean ryodoraku showed statistically significant negative correlation(r=-0.353). Conclusions : These results suggest that ryodoraku maybe used to evaluate chronic low back pain patients.

Objective: To inform of the 4th WHO informal consultation meeting on the development of international standard acupuncture points locations, held in Daejeon, Korea, on April $23{\sim}26$, 2005. Results and Conclusions: 12 experts from Korea, China and Japan discussed the locations of 18 controversial points that were not agreed at the previous meeting, and 16 non-controversial points that all 3 nations agreed on the locations but still needed more discussion for their expressions, as well as other non-controversial points that were agreed on both the locations and the expressions but were suggested by Chinese party to be discussed again. Also, the guidelines for English translation of the standard acupuncture points locations and the development of the standard acupuncture points charts, diagrams, and dolls were discussed in this meeting. Through this meeting the locations of ST30, SP11, SP12, TE18, GB9, GB10, LR4, LR5, LR6, BL6, BL7, BL9, GB19 were agreed, but it was suggested that more research would be needed for the locations of LI20, GV26, PC8, PC9, LR7, GB30, LR12, and the expressions of ST36, ST38, ST39, BL1. Due to the time limitation, 16 acupuncture points out of those Chinese party suggested to have more discussion about were not discussed at this meeting and remained to be discussed at the next meeting.
