Objectives : It is sure that standardization of medical instruments is very important and necessary. Cupping therapy is one of the traditional oriental medical method, and it is necessary to set up a standard of cupping therapy and instruments. Methods : We select 3 major cupping instrument makers according to a questionnaire survey of 2001 oriental medical doctors. Dae Gun is A maker, Han Sol is B maker, Dong Bang is C maker. And with these air pumps we make experiments on stability by an inner impact test and a falling test. With these cups we check stability by an inner impact test and a disinfection test. And to know function of these instruments we test a negative pressure and maintain attached cups until 5 to 10minutes. Results : All results of experiments(impacted test, disinfection test, falling test) on stability of cups and air pumps are suitable for medical instrument. And the efficiency of 3 major makers shows various results. Negative pressure of B group is the highest, C group is the second, A group is the lowest. Pressure maintenance test shows A and C group is comparatively up to the experimental standard(<10%), B group is comparatively below the experimental standard(<10%). Conclusions : Results show stability of cups and air pumps is suitable for medical instruments. And negative pressure of cupping and maintenance of pressure show various results. So it is necessary to set up a standard negative pressure of cupping and maintenance of pressure.

국내의 가뭄피해 사례를 보면 1990년 이후 5~7년 주기로 극심한 가뭄이 발생하고 있는 것을 확인할 수 있다. 특히 2014~2015년에 발생한 가뭄으로 인해 보령댐, 횡성댐, 용담댐에서 역대 최저 저수율을 기록하기도 했다. 기후변화로 인해 가뭄의 발생빈도는 더 짧아지고 강도는 더 증가할 것으로 예상됨에 따라 수자원장기종합계획에서는 기후변화에 따른 극한가뭄 대처 방안 중 하나로 용수공급 예비율의 도입이 필요하다고 언급한 바 있다. 국내 대부분의 다목적댐은 용수공급에 이용되는 이수용량 외에 비상시 활용 가능한 비상용량을 확보하고 있다. 비상용량은 평상시에는 용수공급 목적으로 사용되지 않는 것을 원칙으로 하지만 가뭄과 같은 비상시에는 용수공급에 기여할 수 있는 비상용수로 사용할 수 있다. 하지만 비상용량에 대한 명확한 활용방안이 없어 이를 활용하지 못하고 있는 실정이다. 본 연구에서는 다목적댐의 비상용량을 활용한 용수공급예비율 개념을 도입하고, 낙동강수계 내 다목적댐을 대상으로 적정 예비율을 산정하여 예비율 확보에 따른 용수공급능력의 향상 효과를 분석하여 비상용량의 활용 방안을 제시하고자 한다. 적정 예비율 산정을 위해 낙동강 유역내 6개 다목적댐(안동, 임하, 군위, 김천부항, 합천, 밀양)을 대상으로 저수지 모의운영을 실시하였다. 저수지 모의운영 시 댐 연계운영을 실시하여 수계내 조절점을 기준으로 상류 댐의 수문상황에 따라 방류량을 배분하였다, 또한 기후변화의 영향을 고려한 적정 예비율 산정을 위해 APEC 기후센터에서 생산한 일단위 수문시나리오 자료를 유입량 자료로 이용하였다.

Objectives: To examine the efficacy and safety of cupping therapy for insomnia disorder and provide clinical evidence that could contribute to further research. Methods: We searched randomized controlled trials (RCTs) that verified effects of cupping therapy for insomnia disorder from 11 domestic and foreign databases. Included studies were evaluated using Risk of Bias (RoB). Results: Nineteen RCTs were selected. Wet cupping was more frequently used than dry cupping. Moving cupping was mostly used among dry cupping methods. Dry cupping was mainly performed in Bladder Meridian on the back. Wet cupping was mainly performed on BL18, LR14, and BL15. The most common treatment period was 4 weeks. The average number of treatments per week was about 2.4 times for all types of cupping, about 3.2 times for dry cupping and about 1.9 times for wet cupping. All selected studies showed a significant sleep improvement compared to the control group. As a result of the meta-analysis, in terms of effective rate, SAS score, and SDS score, the wet cupping in combination with acupuncture was significantly more effective than acupuncture alone, although the quality of selected RCTs was low. Conclusions: Cupping therapy is effective for insomnia disorder. Based on results of this study, it is reasonable to use wet cupping two times per week on BL18, LR14, and BL15 or use moving cupping three times per week in Bladder Meridian on the back for 4 weeks to treat insomnia disorder.

Objectives : We developed and proposed a guideline for safety and performance assessment of electric cupping apparatus(Class 2 medical device). Methods : We drafted the guideline for safety and performance assessment of electric cupping apparatus by referring the existing standards and guideline, based on online questionnaire for Korean medical doctors and measurement data from commercially available products. Physical dimension of cups and inner vacuum pressure were acquired for the measurement in order to achieve the purposes. Results : This guideline only can be applied to electric cupping apparatus for enhancing blood circulation by employing negative pressure generated by electricity. Seven items of appearance and label, operation test of pump, variation test of input electricity, vacuum level test, vacuum sustain test, cup-size dependent test, noise level test are suggested for evaluation subjects and methods required for electric cupping devices. Requirements for the design and development of electric cupping devices are suggested: vacuum level indicator, vacuum generation rate, pressure control, valve detachment stability, cup comparability, safety measure, surge protection, user friendliness, instruction for use (IFU). Conclusions : We proposed a guideline for safety and performance assessment of electric cupping apparatus to improve the quality of relating products and aid the commercialization of them, by aiming higher industrial competitiveness of the medical device sectors in Korea. Discussion with related institutes such as industry, academy and government is further required. Public hearings also need to be held prior to the establishment of a final guideline and standard.

A feasibility modeling for potential hydroelectric dam site selection was suggested using 1 sec ASTGTM (ASTER Global Digital Elevation Model) and Terra/Aqua MODIS (Moderate Resolution Imaging Spectroradiometer) derived land use (MCD12Q1) data. The modeling includes DEM pre-processing of peak, sink, and flat, river network generation, watershed delineation and segmentation, terrain analysis of stream cross section and reservoir storage, and estimation of submerged area for compensation. The modeling algorithms were developed using Python and as an open source GIS. When a user-defined stream point is selected, the model evaluates potential hydroelectric head, reservoir surface area and storage capacity curve, watershed time of concentration from DEM, and compensation area from land use data. The model was tested for 4 locations of already constructed Buhang, BohyunMountain, Sungdeok, and Yeongju dams. The modeling results obtained maximum possible heads of 37.0, 67.0, 73.0, 42.0 m, surface areas of 1.81, 2.4, 2.8, 8.8 ㎢, storages of 35.9, 68.0, 91.3, 168.3×10⁶ ㎥ respectively. BohyunMountain and Sungdeok show validity but in case of Buhang and Yeongju dams have maximum head errors. These errors came from the stream generation error due to ASTGTM. So, wrong dam watershed boundary limit the head. This study showed a possibility to estimate potential hydroelectric dam sites before field investigation especially for overseas project.

Objectives : Cupping therapy is a stimulation therapy similar to acupuncture and moxibustion with effects that differ depending on the degree of stimulus. To make the strength of the skin objective in cupping therapy for this study, we measured negative pressure in the cupping jar and calculated the expansion rate of the skin. Subjects and Methods : In this study, we experimented with cupping therapy jars made for sale and used in clinics. We studied the pressure in the jars and the changes on the skin surface by measuring properties. We used commercial jars of four different volumes and diameters and tried to discover the properties on the size of the jar. Results : The results of experiment with the cupping therapy are as follows: 1. The lowest pressure in a jar was measured at $-600{\sim}610mmHg$, and the number of operating of vacuum pump for reaching lowest pressure was increased recording where the volume of the jar would be big, but the lowest pressure was not increased recording where the size of that would be big. 2. As the vacuum pump continued to operate, the pressure gradient in the jar got smaller which shows that the expansion rate of the skin was not linear. The pressure gradient shows different operational numbers on the vacuum pump near 0mmHg/operation unrelated to jar volume. 3. When negative pressure worked on the jar, air in the jar decreased. The percentage of air gradually reduced as the negative pressure acted in the jar. For example, the percentage of skin was 37-66% when the negative pressure, reatched -500mmHg. According to out results, different test areas generate different percentages of air in the jar, presumably related to skin elasticity. This phenomenon was most pronounced with the smallest jars. 4. At -500mmHg, the expansion rate of the skin was 1.57-1.9 on the abdomen, and $1.52{\sim}1.68$ on the back. The expansion rate of the skin appeared greater when the jar was relatively small, and it appeared smaller when the jar volume was relatively large relatively.

Objectives : This study was performed to evaluate the effect of dry cupping treatment applied to back-shu points on the autonomic nervous system. Methods : Two groups of sympathicotonia and normal with each 30 volunteers were set up for this experiment. The sympathicotonia group was selected by the criterion for sympathicotonia by the questionnaire composed of 11 items. After 10 minutes for environmental adaptation, the first HRV(heart rate variability) test was conducted, and then, dry cupping therapy was applied to back-shu points for 5 minutes to stimulate sympathetic ganglia lying along the spine. The second HRV test was carried out just after the cupping therapy under the same condition and then, the third test was repeated after two hours based on the first test time. Results : 1. In sympathicotonia group, SDNN(standard deviation of all normal R-R intervals), RMSSD(the square root of the mean of the sum of the squares of differences between adjacent normal R-R intervals), Ln(HF)(high frequency power), nmHF(normalized high frequency power) increased and mHR(mean heart rate), nmLF(normalized low frequency power) decreased significantly right after dry cupping therapy which means dry cupping affects on autonomic nervous system. The effect lasts in these items of nmLF, Ln(HF), nmHF, rLHF(rate ratio of LF/HF). 2. In normal group, SDNN, RMSSD increased and mHR decreased significantly right after dry cupping therapy, too. But, Ln(LF)(low frequency power), nmLF, rLHF unexpectedly increased and nmLF, rLHF stay increased up to 2 hours. Conclusions : The results suggest that the dry cupping therapy has effect on the autonomic nervous system. It is effective to stabilize hyper-sympathetic tone of people diagnosed as Sympathicotonia and activate parasympathetic tone.
