Objectives: This study was performed to review the research trends in the relationship between primary dysmenorrhea and doppler indicies of uterine artery. Methods: The search for related papers used 'Pubmed', a reserch engine in the America National Library of Medicine and Korean studies Information Service System (KISS). Used searching terms were 'primary dysmenorrhea', 'menstrual pain' in all cases. And among these studies, we searched by using key word 'uterine artery', 'doppler indices', 'doppler parameters', 'pulsatile index', 'resistance index'. Results: Overall 49 studies, 8 studies were finally selected to this study. There were 6 controlled studies and 2 randomised-controlled studies. In all 8 studies, transvaginal ultrasound was used to measure the resistance of uterine blood vessels. All of these studies reported that in patients with primary dysmenorrhea, hemodynamic values of uterine arteries measured by Doppler ultrasound were significantly higher than in normal subjects. Conclusions: According to the results, it was found that there was a positive correlation between the pain level of primary dysmenorrhea and the pulsation index and resistance index of the uterine artery. Based on these results, it can be seen that the doppler indicies of uterine artery have the potential to be used as an evaluation scale for Korean traditional medicine for primary dysmenorrhea.

Objectives: The purpose of this review is to overview the studies of traditional herbal medicine for chronic pelvic inflammatory disease. Methods: We searched relevant studies using seven databases (The Journal of Korean obstetrics & gynecology, National Digital Science Library (NDSL), Research Information Sharing Service (RISS), Oriental Medicine Advanced Searching Integrated System (OASIS), Pubmed, Cochrane, Chinese National Knowledge Infrastructure (CNKI)). Data retrieval was carried out on April 5, 2021 and the papers published from January 1, 2015 to March 31, 2021 were included. The risk of bias was assessed by using Cochrane's risk of bias tool. Results: 524 studies were searched in domestic and foreign databases, and 7 studies were finally selected. In all studies, the treatment group was treated with oral traditional herbal medicine and the control group was treated with western medicine. Although the evaluation index was slightly different for each study, all studies used total efficacy rate index. In all 7 studies, the treatment group was more effective than the control group. Conclusions: Traditional herbal medicine can be an effective option in treating chronic pelvic inflammatory disease. Further high quality studies which include large number should be carried out to confirm the evidence and safety of traditional herbal medicine treatment.

Objectives This study was conducted to evaluate the effect of electro-acupuncture for sciatica. Methods We searched 13 online databases (Kmbase, Research Information Sharing Service [RISS], National Digital Science Library [NDSL], Oriental Medicine Advanced Searching Integrated System [OASIS], Koreanstudies, Koreantk, DBpia, PubMed, Cochrane, EMBASE, Medline, China National Knowledge Infrastructure [CNKI], J-stage) to find randomized-controlled clinical trials (RCTs) that used electro-acupuncture for sciatica. Efficacy rate and visual analogue scale (VAS) were mainly analyzed as a main evaluation criteria. Results Among 583 articles that were searched, 24 RCTs were finally selected and 18 RCTs were statistically analyzed. Electro-acupuncture was more effective than acupuncture in terms of efficacy rate (p<0.00001) and VAS (p<0.00001). Also, Electro-acupuncture was more effective than western medication in terms of efficacy rate (p=0.0005). However, the effectiveness of electro-acupuncture was not identified compared to physical therapy (p=0.42). Electro-acupuncture significantly improved efficacy rate when combined with physical therapy than physical therapy alone (p<0.0001). In addition, electro-acupuncture plus Chuna manual therapy compared to Chuna manual therapy alone showed positive results for efficacy rate (p=0.05) and VAS (p<0.0001). Conclusions Based on results, the effectiveness of electro-acupuncture for sciatica was identified. However, this study has limitations because the RCTs included in this study were small in number and published in a particular region. Although this study could be a groundwork for well designed research for sciatica.

Objectives: The purpose of this study is to analyze the effectiveness of Guibi-tang that are used for postpartum depression. Methods: We searched on five databases [Korean studies Information Service (KISS), Oriental medicine advanced searching integrated system (OASIS), The Cochrane Library, PubMed, and China national knowledge infrastructure (CNKI)] with keywords for Postpartum depression (English, Korean, and Chinese) and evaluated the risk of bias. Meta-analysis was performed on the selected studies. Results: 8 potentially relevant articles were retrieved for further evaluation. There was evidence that Guibi-tang compared with Western medicine was significantly higher rate in total effect rate (RR 1.20, 95% CI 1.04, 1.39, p=0.01). Also, the combined therapeutic effects of Guibi-tang and Psychological intervention compared with Psychological intervention were statistically significant in total effect rate (RR 1.14, 95% CI 1.05, 1.24, p=0.002). And they showed improvement on scores of HAMD (Hamilton depression scale, HAMD) and SF-36 (36-Item short form health survey, SF-36). Conclusion: Guibi-tang appears to be more effective compared to Western medicine in the treatment of postpartum depression. The combination Guibi-tang and Psychological intervention was more effective than psychological intervention alone treated for postpartum depression. However, since unclear risk of bias, the result of this study should be considered carefully. Further clinical trials should be carried out in order to academical clinical progress regarding treatment of Postpartum Depression.

Objectives The purpose of this study is to systematically review the degree of pain and function improvement in acupuncture treatment for patellofemoral pain syndrome (PFPS). Methods Randomized controlled trials (RCTs) were searched from Medline/PubMed, Cochrane Library, Embase, WanFang Data, China National Knowledge Infrastructure (CNKI), Citation Information by NII (CiNII), Koreanstudies Information Service System (KISS), ScienceON, KoreaMed, and Korean Medical Database (KMbase). The methodological quality of selected RCTs' were evaluated according to Cochrane RoB2 tool. Results Total of 158 studies were identified and 7 RCTs were selected for systematic review. Frequently used evaluation method were visual analogue scale and Kujala scores. All studies showed significant effect on pain reduction and knee function between before and after treatment, but showed partial significance between the intervention and control group. Conclusions Research showed that acupuncture treatment is an effective treatment for improving the pain and function of PFPS, but it is difficult to conclude that it has a significant effect compared to other treatments. Selected studies included subjective evaluation indicators and the total of selected studies were small, so the interpretation of the results is limited. Also most of the included studies are evaluated to have some concerns of bias. Therefore, subsequent research should continously be done in more objective and systematic method.

날씨와 지역에 관계없이 언제나 지구상의 위치를 파악할 수 있도록 하는 위성항법시스템은 해양분야에도 많은 응용기술과 시스템의 개발을 촉진하고 있으며 이러한 경향은 LBS(Location Based Service)라고 하는 기술분야로 응용분야가 확대되고 있다. 해양의 LBS는 아직 본격적인 개발이 이루어지고 있는 것은 아니지만, 이러한 시스템들은 일반적으로 지형정보를 사용하게 되는데, 해양의 기본 지형정보로는 전자해도 (ENC, Electronic Navigational Chart)를 사용하게 될 것이다. 그러나 앞에서 말한 시스템들과 전자해도는 그 규모에 있어 대형선과 고용량의 처리능력을 갖는 시스템에 사용되므로 어선이나 레저용 보트와 같은 소형선용 시스템에는 적합하지 않다. 이를 해결하기 위해 시스템의 소형화 및 사용 데이터의 소형화가 필요하며 근래 각광을 받고 있는 PDA, 웹패드와 같은 모바일 플랫폼 기반의 시스템이 그 대안이 될 수 있다. 본 논문에서는 이러한 배경으로 대두된 소형시스템에의 지형정보 사용, 특히 국가공인 데이터인 전자해도를 모바일 플랫폼에서 사용하기 위한 전자해도의 소형화 방안을 연구하였다. 전자해도는 그 구조와 내용에 많은 부가정보와 형식을 갖고 있다. 그러므로 소형시스템에 필요한 데이터의 내용과 형식의 측면을 고려하여 데이터를 소형화하기 위한 방안을 제시하였고, 또한 전자해도의 갱신을 수용할 수 있어야 한다는 점을 함께 고려하였다. 데이터의 소형화는 상당한 데이터 및 정보의 손실을 감수해야하는 경우가 많다. 본 논문을 통해 가능한 적은 데이터와 정보의 손실만으로 모바일 플랫폼기반의 시스템에 부담없이 사용 가능한 전자해도의 소형화 방안을 제시하여 향후 도출될 수많은 소형시스템 응용분야에 활용할 수 있을 것으로 기대한다.작용 등의 복잡한 물리적 과정을 포함하고 있다. 이러한 물리적 과정 중 난류연소, 고체연료 벽면 근방에서의 대류 열전달 및 연소과정에서 생성되는 soot 입자로부터의 복사 열전달, 그리고 고체연료 열 분해시 표면반응들은 고체연료의 regression율에 큰 영향을 미친다. 특히 고체연료의 난류화염면의 위치와 폭, 그리고 비 예혼합 난류화염장에서 생성되는 soot의 체적분율의 예측은 난류연소모델, 열전달 모델, 그리고 regression율 모델에 의해 크게 영향을 받기 때문에 수치모델의 예측 능력 향상시키기 위하여 이러한 물리적 과정을 정확히 모델링해야 할 필요가 있다. 특히 vortex hybrid rocket내의 난류연소과정은 아래와 같은 Laminar Flamelet Model에 의해 모델링 하였다. 상세 화학반응 과정을 고려한 혼합분율 공간에서의 화염편의 화학종 및 에너지 보존 방정식은 다음과 같다. 화염편 방정식과 혼합분률과 scalar dissipation rate의 관계식을 이용하여 혼합분률과 scalar dissipation rate에 따른 모든 reactive scalar들을 구하게 된다. 이러한 화염편 방정식들을 mixture fraction space에서 이산화시켜서 얻은 비선형 대수방정식은 TWOPNT(Grcar, 1992)로 계산돼 flamelet Library에 저장되게 된다. 저장된 laminar flamelet library를 이용하여 난류화염장의 열역학 상태량 평균치는 presumed PDF approach에 의해 구해진다. 본 연구에서는 강한 선회유동을 가지는 Hybrid Rocket 연소장내의 난류와 화학반응의 상호작용을 분석하기 위하여 Laminar Flamelet Model, 화학평형모델, 그리고 Eddy Dissipat
