Objective: I carried out this study for research on thermographic change of DITI by Sugi Therapy. Methods: This study was conducted on 22 normal cases (M : F =4:18) with no past history to observe the effect of Sugi Therapy. 22 cases were divided into 2 groups. One group is a control group treated by only Acupuncture Therapy. The other group is a treatment group treated by Acupuncture Therapy and Sugi Therapy. I measured temperature of abdomen and palm by DITI (Digital Infrared Thermographic Imaging) before and after treatment Result: 1. Overall the temperature difference of the treatment group was bigger than that of the control group. 2. On the palm, the average value of the treatment group was -0.56±0.70, which is lower 10 times than -0.06±0.91 of the control group. 3. On Chung-wan(CV12), the average value of the treatment group was 1.20±0.49, which is 2.15 times higher than 0.56±0.44 of the control group. 4. On Kwanwon(CV4), the average value of the treatment group was 0.77±0.73, which is 1.38 times higher than 0.55±0.39 of the control group. 5. To compare the temperature difference on the palm, Chung-wan(CV12) and Kwanwon(CV4) before and after treatment, the order is like this :Chung-wan(CV12) > Kwanwon(CV4) > palm of all treatment group and control group. Conclusion: I came to a conclusion that Sugi Theraphy is likely to work better with Acupuncture Therapy better than only Acupuncture Therapy, especially on Chung-wan(CV12).

Objectives : This study was designed to find out whether there is a correlation between qi-stagnation score and pressure pain threshold (PPT) on acupuncture point $CV_{17}$ in burning mouth syndrome (BMS) patients. Methods : Thirty BMS patients who newly visited Oral Disease Clinic at the Kyung Hee University Korean Medicine Hospital were surveyed. The subjects were evaluated on age, illness duration, sex, self-assessed severity of BMS, qi-stagnation score, and PPT on 3 acupuncture points ($CV_{17}$, Rt. $SP_9$, Lt. $SP_9$). Results : There was significant correlation between age and PPT on $CV_{17}$ (p=0.005). Therefore, partial correlation analysis with age as control variable was done, and the result showed significant correlation between qi-stagnation score and PPT on $CV_{17}$ (p=0.001). Qi-stagnation diagnostic point by PPT on $CV_{17}$ was suggested as 3.8056 $kg/cm^2$ based on the fact that diagnostic score is 28.50 in the qi-stagnation questionnaire. Furthermore, considering that PPT is effected by age, we could attain qi-stagnation diagnostic equation of PPT on $CV_{17}$, that is suggested as $0.047{\times}(age)+0.848kg/cm^2$. PPT of 3 acupuncture points ($CV_{17}$, Rt. $SP_9$, Lt. $SP_9$) was compared, and the result showed that PPT was significantly lower on $CV_{17}$ (w/Rt $SP_9$: p=0.022, w/Lt. $SP_9$: p=0.012). Also, significance and correlation coefficient with qi-stagnation were higher on $CV_{17}$ (p<0.001, r=-0.620) than Rt. $SP_9$ (p=0.023, r=-0.413) or Lt. $SP_9$ (p=0.014, r=-0.444). Conclusions : The result of this study suggested that PPT on $CV_{17}$, measured quantitatively by algometer, had a strong correlation with qi-stagnation score in BMS patients. Therefore, the study showed that $CV_{17}$ can be a useful acupuncture point in diagnosing qi-stagnation by measuring PPT in BMS patients.

고분자 전해질막 연료전지의 대량 생산을 위하여 막-전극 접합체(MEA) 활성화 방법의 개발이 중요한 현안이다. 현재 개발된 MEA활성화 방법은 시간이 많이 소요됨으로 인해 수소의 사용량 또한 증가하여 연료전지의 상용화에 큰 걸림돌이 되고 있다. 통상적인 활성화 방법은 활성화 원리를 주로 전해질 수화 관점에서 이해하였다. 반면, 본 논문에서 제안된 순환전압전류(cyclic voltammetry, CV) 활성화 방법은 전해질 및 촉매적 관점에서 별도로 분리하여 이해하였다. 따라서 전해질 관점에서는 상대 습도 100%인 가습된 질소를 공급하여 전극 및 막의 전해질을 수화시키는 과정으로 구성되고, 촉매적 관점에서는 CV 사이클을 수행하여 백금 촉매에 흡착되어 있는 불필요한 오염물질, 또는 산화피막을 제거하는 과정으로 수행된다. CV 활성화법은 2.5 h 내에 활성화가 종료되어 활성화 시간을 크게 단축시킬 수 있을 뿐만 아니라, 수소 사용량도 기존 활성화 방법에 비하여 1/4 이하로 감소시킬 수 있어서 효과적인 연료전지 활성화 방법으로 제안하고자 한다.

CV graphite cast iron has been studied and generally known to have properties close to the average values of those between flake and spheroidal graphite cast iron. However, the thermal diffusivity of CV graphite cast iron is much larger than that of the average value of those between flake and spheroidal graphite cast iron. In this study, an easy production method of CV graphite cast iron with small additions of a Al-Cu which is known as the element of the graphitization was investigated. The effects of hold time and of Al-Cu additions after the treatments with spheroidizer (Fe-Si-Mg alloy) were also investigated. Increasing the additions of a Al-Cu alloy, the holding time to form a CV graphite cast iron was decreasing. Tensile strength and thermal diffusivity (flash method) were measured in order to find the changes of the mechanical properties and the physical properties. Spheroidal, CV, and flake graphite cast iron have tensile strengths 46.44, 38.29, and $27.29\;kg/mm^2$ and thermal diffusivities $3.95{\times}10^{-6,}$ $8.41{\times}10^{-6}$, $8.81{\times}10^{-6}m^2/sec$, respectively at room temperature.

Objectives : This research aimed to verify the validities of contraindicated acupoints in acupuncture treatment in Zhenjiudacheng. Methods : We investigated contraindicated acupoints when performing needling in Zhenjiudacheng, then verified them in today's medical knowledge and clinical studies. Results : In Zhenjiudacheng, 39 acupoints - LU2, LI4, LI13, LI14, LI16, ST1, ST9, ST12, ST17, ST25, ST30, ST42, SP6, SP11, SI18, BL8, BL9, BL56, KI11, TE7, TE8, TE19, TE20, GB3, GB18, GB21, GV10, GV11, GV17, GV22, GV24, CV1, CV4, CV5, CV8, CV9, CV15, CV17 and EX-HN11 - were described to need a careful approach in acupuncture treatment and 21 acupoints among them had contraindications. Most of the contraindications can be explained based on anatomical knowledge and results of clinical studies, and acupuncture treatment at the 39 contraindicated acupoints can induce injury of tissues or organs near the acupoints. Conclusions : The contraindicated acupoints in acupuncture treatment in Zhenjiudacheng seem to have been classified based on the adverse events experienced by doctors at that time. Therefore careful acupuncture treatment at these acupoints is needed to avoid injury to tissue or organs.

Several lines of evidence indicate that adenosine $A_{2A}$ agonist disrupts spatial working memory. However, it is unclear which stages of learning and memory are affected by the stimulation of adenosine $A_{2A}$ receptor. To clarify these points, we employed CV-1808 as adenosine $A_{2A}$ agonist and investigated its effects on acquisition, consolidation, and retrieval phases of learning and memory using passive avoidance and the Morris water maze tasks. During the acquisition phase, CV-1808 (2-phenylaminoadenosine, 1 and 2 mg/kg, i.p.) decreased the latency time in passive avoidance task and the mean savings in the Morris water maze task, respectively. During the consolidation and retrieval phase tests, CV-1808 did not exhibited any effects on latency time in passive avoidance task and the mean savings in the Morris water maze task. These results suggest that CV-1808 as an adenosine $A_{2A}$ agonist impairs memory acquisition but not consolidation or retrieval.

모자이크증상을 나타내는 열무로부터 Cucumber mosaic virus의 한 계통을 분리하고 특성을 조사하였다. Vigna unguiculata, Chenopodium amaranticolor and Gomphrena globosa에서 분리 바이러스의 기주반응과 dsRNA 분석, RT-PCR 검정, PCR-RFLP, 혈청학적 분석을 통하여 CMV의 한 계통임을 확인하였다. 이 CMV 계통을 다양한 지표식물에 접종하였을 때, Nicotiana benthamiana와 N. glutinosa, N. tabacum, 고추, 오이 그리고 멜론에서는 전형적인 강한 모자이크 병징이 나타났으나, 열무, 배추, 적갓은 매우 약한 병징을 나타내는 특징을 보였다. 새롭게 분리된 CMV 계통은 가지과, 박과 및 배추과 등 광범위한 작물에 감염성을 나타내었으며, 배추과에서의 감염성 차이를 근거로 Gn-CMV로 명명하였다. Double-stranded (ds) RNA를 분리한 분석에서 Gn-CMV는 기 보고된 CMV 계통과 마찬가지로 3.3, 3.0, 그리고 2.2 kb의 독립된 게놈으로 구성되어 있었으며, SDS-PAGE와 Western blotting 분석으로 통하여 28 kDa의 외피단백질을 확인할 수 있었다. RT-PCR로 얻어진 증폭산물을 Cac8I, ClaI and MspI을 이용한 PCR-RFLP를 통하여 CMV subgroup I 임을 확인할 수 있었다.
