Objectives : The purpose of this study is to report the clinical effects of Korean medical treatment for Kienb$\ddot{o}$ck's disease. Methods : The patient was treated using acupuncture, electroacupuncture, herbal medicine, pharmacopuncture treatment, and other treatments including moxibustion, physical rehabilitation for 6 weeks. And we evaluated the patient through verbal rating scale(VRS), disability of the arm, shoulder and hand(DASH), range of motion(ROM). Results : After treatment, VRS is changed from 7 to 3, DASH is changed from 37.93 to 20.69. And ROM is changed from $60^{\circ}$ to $70^{\circ}$ in wrist flexion, and from $10^{\circ}$ to $15^{\circ}$ in radial deviation. Conclusion : These results suggest that Korean medical treatment is effective to the patient complaining pain and dysfunction.

Purpose: We intended to observe the relations between Chiljehyangbuhwan and abdominal temperature according to primary dysmenorrhea severity. Methods: We selected the 100 primary dysmenorrhea patients by the screening tests (first screening test-inquiry, second screening test-clinical test, additionally WHR (Waist-to-Hip ratio) by Inbody 2.0). By the fixed blocked randomization and double blind method, Chiljehyangbuhwan or placebo was administered for 1 menstration period. Finally, 69 patients remainded. Before and after administration, we measured 4 points abdominal temperature (Chon-jung(CV17), Chung-wan(CV12), Kwan-won(CV4), Chung-guk(CV3)) by DITI (DOREX Inc., USA). And then we checked the difference of temperature $({\Delta}T)$ between CV17 and CV12 / CV17 and CV4 / CV17 and CV3 / CV12 and CV4 / CV12 and CV3. After that, we compared ${\Delta}T$ with primary dysmenorrhea severity evaluated by VRS (verbal rating scale) and MVRS (multidimensional verbal rating scale). In dysmenorrhea severity, we standardized scale score and 3-group-severity by score (mild, moderate, severe). For statistics, we used Pearson correlations and Spearman's rho correlations, SPSS 11.0 for windows. Results: In case of MVRS, Chiljehyangbuhwan was correlated to ${\Delta}T$ (CV12 and CV3 / CV12 and CV4). In case of VRS, Chiljehyangbuhwan was not correlated to ${\Delta}T$. Statistically they showed significant result (p<0.05). Conclusion: The primary dysmenorrhea patients showed that severity by MVRS was connected with ${\Delta}T$ (CV12 and CV3 / CV12 and CV4) after Chiljehyangbuhwan administration. So we can consider Chiljehyangbuhwan effects the abdominal temperature according primary dysmenorrhea severity.

Background: Tramadol administered epidurally is known to have one-thirtieth the potency of morphine for treatment of pain following abdominal surgery. We designed a prospective, randomized, controlled study to evaluate the analgesic efficacy and safety of combined epidural infusion of bupivacaine and tramadol with 2-day infusor as ompared to bupivacaine and morphine combined epidural infusion. Methods: Sixty healthy women scheduled for Cesarean delivery were assigned randomly in double- blind fashion: Group 1 (n=20) were given a mixture of morphine 10 mg(1 ml), 0.5% bupivacaine 40 ml and normal saline(NS) 40 ml; Group 2(n=20) a mixture of tramadol 300 mg(6 ml), 0.5% bupivacaine 40 ml and NS 54 ml; Group 3(n=20) or a mixture of tramadol 500 mg(10 ml), 0.5% bupivacaine 50 ml and NS 50 ml, of continuous dose via epidural route following 1% lidocaine 6 ml as bolus dose for 48 hours postoperatively. We evaluated the analgesic efficacy and side effects of these three groups using visual analogue pain scale (VAPS) and verbal rating scale (VRS). Results: VAPS of group 1 and 3 were lower than group 2, and VAPS of group 1 was lower than group 3(12, 24, 36, 48 hours). VRS of group 1 and 3 were lower than group 2 (12, 24, 36 hours). There were incidences of pruritus was 16 patients in group 1. Conclusions: Tramadol does possess the analgesia effect of morphine, but has the added analgesia following increment. Further research to determine the most effective administration method and reguired dosage of tramadol is further needed.

iRTK 시스템을 개발하고 측위정확도 검증을 위해 중저가 수신기를 이용한 실험을 수행하였다. 각기 다른 네 가지 기선에 대해 iRTK 시스템을 이용한 측위실험이 이루어겼고, 1-3m수준의 측위정확도를 얻을 수 있었다. 제안하는 iRTK 기법은 기존의 RTK와 적용범위 및 정확도는 유사하지만, 중앙처리센터에서 일괄적으로 사용자의 위치를 계산하는 점이 다르며 유무선 인터넷을 이용하므로 통신범위에 제약을 받지 않는 장점이 있다. 그러나 유효응용범위가 5km미만인 단점도 있다. 따라서 향후 iRTK시스템의 효율적인 전국서비스에 대비한 보완책의 한 방안으로 VRS의 도입을 검토하였다.

Objectives: The purpose of this study is to investigate the relationship between granulocyte/lymphocyte ratio and dysmenorrhea, history of gynecological disease, heart rate varibility(HRV). Methods: From May 1st 2011 to July 10th 2011, a total of 40 female subjects (age 20-39) were recruited. We evaluated the menstruation condition by questionnaires including VAS(Visual Analog Scale), VRS(Verbal Rating Scale) and MVRS (Multidimensional Verbal Rating Scale), also measured subject's WBC differential count and HRV. Results: 1. There was no statistically significant difference in granulocyte/lymphocyte ratio according to menstruation cycle, duration, amount, color, and blood clot. 2. There was no statistically significant difference in VAS, VRS, MVRS mean scores between normal group and abnormal group according to granulocyte/ lymphocyte ratio. 3. The past prevalence of gynecological disease of abnormal group showed significantly higher compared with that of normal group($x^2$=6.578, p=0.010). 4. LF/HF ratio and granulocyte ratio significantly showed positive correlation ($r_s$=0.311 p=0.048) and LF/HF ratio and lymphocyte ratio significantly showed negative correlation($r_s$=-0.319 p=0.045). Conclusion: These findings suggest that the gynecologic diseases are related to disorder of autonomic nervous system, but not dysmenorrhea. And the balance state of sympathetic/parasympathetic nerve infered through granulocyte/lymphocyte ratio and HRV seems to be consistent. However, reconfirmation through further studies is needed.

Background: To improve muscle flexibility, static stretch is the most common type and is considered safe and effective for improving overall flexibility of muscles. During the stretch, the intensity is more likely to be determined by the degree of an athlete's pain and practitioner's skills rather than quantitative measures of stretch. It is necessary to determine the optimal intensity for the stretch. Objects: The purpose of this study is to explore the relationship between hand held dynamometer (HHD) and verbal rating scale (VRS) in comparison of the effects of continuance time on active (walking) and inactive (sitting) movement after static stretch. Methods: A cross-sectional study was conducted with a sample (n=62) recruited from a university. Participants were randomly assigned to 2 different groups (n=31 for each group) based on participants' positions either remaining in sitting or freely walking around for a series of re-assessments. Data was collected at pre-warm up, pre-stretch, post-stretch, and additional assessments at the time of 3, 6, 9, 12, 15, 20 and 30 minutes after the stretch. Results: Relationship between VRS and HHD scores represents very weak correlation (Spearman's p=-.16, p>.05). Pearson's correlation analysis was conducted following the logarithmic transformation of the two scores. Pearson's correlation after the transformation still showed a very low relationship and a poor linear relationship between the two scores (Pearson's r=-.18, p>.05). Conclusion: The optimal intensity for stretch cannot be solely determined by the subjective pain perception. The objective measurement such as HHD could be used in conjunction with the pain perception.

보은과 괴산에 위치한 GNSS상시관측소의 GNSS관측자료와 경사계자료를 이용하여, 1시간과 3시간 동안의 GNSS 차분벡터의 변위와 시간에 따른 차분 경사 벡터의 변위를 계산했다. 그리고, 시간에 따른 두 변위 사이의 관련성을 얻었다. 이렇게 계산된 관련성은 ‘높음‘보다는 낮았다. 그러나, 일사량의 일변화는 일어남이 확실하고, 측정 결과 안테나탑의 경사 변위 때문에 안테나 위상중심 위치의 회전 운동이 존재함이 확실하므로, 우리는 DGNSS에 있어서 보정 오차를 방송할 때와 가상기준국체계(VRS)에 있어서 상시관측소에서 측정된 자료를 방송할 때에 안테나 위상중심 위치의 일변화를 고려할 것을 제안한다.
