In this study, a hybrid multi-cup electric cupping system (HMECS) was proposed, based on the ancient cupping method. HMECS consisted of several cups that could be used simultaneously to treat different areas of the patient's body. Each cup was equipped with its own pump and pressure-monitoring system. Moreover, the vacuum pressure of the cups was controlled using fuzzy logic. Through automated control of the vacuum pressure, long-term relief of muscle tightness was achieved. To develop a scientific foundation for this alternative treatment, we compared the VAS(Visual Analog Scale) and ODI(Oswestry Disability Index) scores from conventional basic cupping to the VAS and ODI scores for our proposed HMECS. The improvement rate in the VAS and ODI scores using HMECS after three treatments was higher than that achieved by basic cupping. These results, combined with the convenience offered by enhanced IT capabilities, should increase the popularity of this device among an aging society, and facilitate the opportunity to further explore the potential of Oriental medical practices.

A multi-cup electric cupping system (MECS) was proposed, based on the ancient cupping method. MECS consisted of several cups that could be used simultaneously to treat 85 lumbago patients. Each cup was equipped with its own pump and pressure-monitoring system. The vacuum pressure of the cups was controlled using fuzzy logic. Through automated control of the vacuum pressure, long-term relief of muscle tightness was achieved. To develop a scientific foundation for this alternative treatment, we compared the Oswestry Disability Index (ODI) scores from conventional basic cupping to the ODI scores for our proposed MECS. The ODI scores using MECS decreased from $11.71{\pm}1.61$ before treatment to $4.81{\pm}1.48$ and $1.87{\pm}1.61$ after three and five treatments, respectively. The improvement rate in the ODI scores using MECS after three treatments was higher than that achieved by basic cupping. These results, combined with the convenience offered by enhanced information technology and fuzzy logic capabilities, should increase the efficiency of this device, and facilitate the opportunity to further explore the potential of Oriental medical practices.

당뇨병 환자의 혈당검사시 통증을 최소화하는 새로운 진공 자동 채혈기법을 개발하였다. 특별히 고안, 제작된 채혈기구를 사용하여 전완부위에서 채혈침으로 피부를 관통한 직후 자동적으로 -100mmHg의 진공압력이 가해짐으로써 모세혈액이 흡입되는 자동화된 진공 채혈기법을 구현하였다. 진공 자동 채혈기법의 유용성을 검증하기 위하여 전완부위에서의 채혈용적을 측정하였다. 58명의 정상인을 대상으로 464회의 채혈을 시행한 결과 평균 채혈용적은 약 2.6$\muL$이었고 0.5$\muL$이상의 채혈빈도가 약 86%이었다. 최근 개발되고 있는 혈당계들은 0.3~0.5$\muL$의 모세혈액으로 혈당검사가 가능하므로 검사성공률 역시 약 86%로 추정되었다. 채혈통증 감소효과를 평가하기 위하여 손가락 및 전완부위 채혈 후 시각상사 통증척도를 사용하여 통증지수를 측정하였다. 전완부위 채혈시 통증은 손가락 채혈의 약 23%에 불과하였으며 거의 무통증 채혈이 가능하였다. 따라서 본 연구의 전완부위 진공 자동채혈기법은 전통적인 손가락 채혈에 비해 채혈통증이 25% 이하로 현저하게 감소하지만 검사실패율이 14%로써 경우에 따라 재채혈이 필요할 수 있다. 그러나 매일 수 차례 채혈해야 하는 만성 당뇨환자의 경우 검사기피를 방지할 수 있는 유용한 방법으로 생각된다.

Objectives : This study aimed to review randomized controlled trials of acupuncture performed in South Korea that used sham acupuncture as a control group. Methods : The following databases were searched through the end of September 2011: Koreanstudies information service system (KISS), Korean medical database (KMbase), national discovery OR science leaders (NDSL), oriental medicine advance searching integrated system (OASIS), and research information service system (RISS). The following search terms were used: acupuncture AND (sham or placebo). The reference lists of searched articles and Korea institute of oriental medicine (KIOM) reports(2005~2009) were identified. The following data were extracted: year/first author, disease, number of participants, blinding, intervention, outcome, and result. Where appropriate, we performed meta-analysis. The methodological quality was assessed according to the Jadad scale and 'risk of bias' by Cochrane Handbook procedure. Results : Twenty-nine studies were included in this review. In eighteen studies, penetrating sham controls were used as the control intervention, whereas the remaining eleven studies adopted non-penetrating sham controls such as the Park Sham Device or blunt auricular acupuncture. Nine studies showed statistically significant difference in outcomes. Twelve studies concerning insomnia after stroke, chronic tension-type headache, idiopathic Parkinson's disease, Hwa-Byung, and smoking cessation were included in meta-analysis. A meta-analysis of insomnia after stroke only found significant difference(MD -4.31, 95% Cl -6.19 to -2.42, $p$<0.00001). In general, all of the studies showed low methodological quality(Jadad score: mean 2.1). Risk of bias by Cochrane Handbook procedure varied. Conclusions : The results of this study could not suggest conclusive evidence that acupuncture is more effective than sham acupuncture in several diseases. In the future, more studies with rigorous acupuncture trials using sham controls should be conducted.

Objectives: This was a retrospective case series about the clinical effect of integrated approach with behavior therapy for obstructive sleep apnea (OSA). Methods: Medical records of twelve patients with OSA who were treated with behavior modification including nasal breathing with oral appliances and sleep in lateral position, oral administration of herbal medicines and acupuncture treatment between January and September of 2013 were reviewed. Apnea-hypopnea index (AHI), day time sleepiness, apneas and hypopneas counts during sleep, risk indicator (RI), oxygen desaturation index, average saturation during sleep, lowest desaturation, lowest saturation, snoring events ratio and number of desaturations (%) were assessed before and after treatments with the ApneaLink device, which is a portable diagnostic apparatus for monitoring airflows of the patient's breath at home. Results: After an average 62.67 (SD 37.16) days of treatment, AHI (from 17.67, 12.79 to 8.75, 8.25, p=0.007), RI (from 22.00, 13.26 to 12.09, 8.03, p=0.004), oxygen desaturation index (from 17.33, 12.17 to 8.17, 7.86, p=0.005), and number of desaturations (from 7.00 times, 9.79 to 0.92 times, 1.39, p=0.044) showed significant improvement. Daytime sleepiness improved from 6.5 (3.2) to 3.8 (1.8) but there was no significant difference after treatment (p=0.17). No adverse events related to treatment were observed during participation in the treatment. Conclusion: From this case series, we found that behavior modification with herbal medication and acupuncture may be effective for improving sleep apnea without serious adverse events. Future randomized controlled trials with larger sample size will be necessary for concrete evidence on the benefit of this integrated treatment for OSA.

To develop cardiovascular simulator capable of implementing pulse waves similar to the human body, accurate information about reflection wave is required. However, the conclusion is still not clear and various discussions are underway. In this study, the pulse wave velocity of the tube used in the experiment was first determined by measuring the pressure waves at two points in a single tube system with the experimental device to implement the pulse wave transmission of blood vessels, and the superposition time and characteristics of the reflection wave were confirmed. After that, an air chamber was set at the reflection site, and the effect of the change of air volume on the reflection wave was investigated. Finally, the effect of the number of branches connected to a single tube on the reflection wave was investigated. The superposition time of the reflection wave can be controlled by the air volume of the air chamber, and the magnitude of the reflection wave is influenced by the number of reflection sites that generate the reflection wave. The results of this study may be of practical assistance to simulator researchers who want to implement pulse wave similar to clinical data. It is expected that the more results similar to clinical are provided, the greater the scope of the simulator's contribution to clinical cardiovascular research.

Purpose: To analyze the newly developed vacuum assisted auto-lancing technique applied to the forearm for the purpose of obtaining an adequate blood sample for glucose test with minimal pain. Methods: Visual and facial pain measures were introduced to compare lancing pain between the forearm and fingertip in 58 normal females. Sampled blood volumes were accurately measured by computer scanning technique. Results: Visual pain measure demonstrated significant pain reduction effect of the forearm sampling compared with the traditional fingertip sampling, which was also consistent with facial pain measure results. Blood volume more than $0.5{\mu}L$, enough for blood glucose testing with modern glucometers, was collected in 399(86%) of 464 forearm samples. Conclusions: Capillary blood sampling could be performed with minimal pain on the forearm by the newly developed vacuum assisted auto-lancing technique. With some resampling when necessary, the forearm sampling seemed very useful, considering almost no pain felt by the patients.
