습관성 유산의 한의학적 치료에 대한 국내 임상 연구 고찰
권한슬,김형준,강소현 대한한방부인과학회 2023 大韓韓方婦人科學會誌 Vol.36 No.3
Objectives: The purpose of this study is to investigate the domestic study trends on habitual abortion treated with Korean medicine. Methods: We searched the studies on habitual abortion treated with Korean medicine via searching 5 Korean web databases. After searching studies, we analyzed 7 studies selected according to the selection and exclusion criteria. Results: Of the seven selected studies, five case-reporting studies and two retrospective chart analysis. The most applied intervention for habitual abortion was herbal medication. All patients took herbal medicine before pregnancy, and Seunggum-dan was widely used. 66.3% of pregnant patients after treatment took herbal medicine after pregnancy, and Anjeonyichen-tang was the most widely used. As a result of analyzing retrospective chart analysis studies, whether the patient's age was 35 years or older has a significant impact on the success rate of Korean medicine treatment. Conclusions: This study has provided a basis for using Korean medical intervention in the treatment of habitual abortion in clinical practice. In order to provide a more high-quality basis, reliable follow-up studies related to the effectiveness and stability of Korean medicine treatment for habitual abortion should be conducted in the future.

자동변속기(Automatic transmission) 차량은 운전의 편리함, 원활하고 강력한 발진, 가속성, 변속의원활성, 낮은 변속충격 등 수동변속기에 비해 많은 장점이 있으나, 유체의 의해 동력이 전달되는 특성 때문에 동력손실이 불가피하다는 단점을 가지고 있다. 이러한 이유로 자동변속기 차량의 연료효율은 수동변속기 보다 낮게 된다. 이를 보완하기 위해 토크 컨버터(Torque converter)가 가지고 있는 특성 중 하나가 록업 기능이다. 록업 클러치(Lock up clutch)는 차량이 고속으로 주행할 때, 연비향상을 위해 엔진과 변속기를 직결하기 위한 장치로서 수동변속기의 클러치와 비슷한 구조 및 특성을 가진다. 차량 엔진의 고 토크화로 인해 자동변속기에 전달되는 토크 용량이 증가됨에 따라 토크컨버터의 록업클러치 용량이 증가되어야 한다. 록업 클러치의 용량 증대를 위한 중요 기능 부품 중에 하나가 마찰재이다. 협소한 공간 내 록업클러치 용량 증대를 위해 마찰재의 면적을 증대하거나 다수의 마찰재를 적용하게 되는데, 이로 인해 드래그 토크(Drag torque)가 존재하게 된다. 이러한 드래그 토크는 엔진에 불필요한 부하를 가해주므로 연비 저하, 시동불량 등을 발생시키는 요인이 된다. 특히, 최근에는 혹한기의 한파로 인해 극저온품질 향상 방안 검토의 필요성이 대두되고 있다. 극저온에서는 자동변속기유의 점도가 낮아짐에 따라 드래그 토크가 커지므로 엔진에 부하를 많이 주게 되고, 이에 따라 차량의 시동성 불량이 특히 문제가 되고 있다. 이러한 극저온환경에서의 드래그토크는 차량시동성에 악영향을 주며, 반드시 해결해야 할 과제이다. 연구 과정은 해석과 설계를 통해 저온 드래그토크를 감소시켜 시동성을 향상시킬 수 있는 조건을 검토하고 실제 프로토제품을 제작하여 시험으로 검증하고자 한다.

CARE(CAse REport) 지침에 따른 2019-2024년 대한한방부인과학회지 증례보고의 질 평가
권한슬,윤예진,김형준 대한한방부인과학회 2024 大韓韓方婦人科學會誌 Vol.37 No.2
Objectives: The purpose of this study is to evaluate the quality of case reports published in the Journal of Korean Obstetrics and Gynecology from April 2019 to February 2024, compared with January 2015 to March 2019. Methods: Case reports were selected by searching from archive on the website of society of the Journal of Korean Obstetrics and Gynecology. The quality of the case reports were assessed based on CAse REport (CARE) guideline. Results: A total of 30 case reports was finally included for the assessment. Overall quality of reporting for case reports published from April 2019 to February 2024 was improved compared to one of previous study. However, the 4 items of CARE guidelines with an unreported rate of 50% or more - patient’s perspective on interventions (96.67%), diagnostic challenges (93.33%), intervention adherence and tolerability (93.33%), adverse events (56.67%) - are items that require active description in future case reports. In addition, Keyword and timeline have more than 50% reported to be ‘Not-sufficient' in both previous and present studies. So active efforts by researchers are needed to include ‘Case report (or Case study)’ in keywords, and to include intervention by period, symptom changes in a timeline. Conclusions: Despite the overall improvement in the quality of reporting in the Journal of Korean Obstetrics and Gynecology, efforts to improve the quality of case reports should be continued.

비스테로이드성 소염진통제를 복용하는 원발성 월경곤란증 환자에 대한 이침치료의 무작위대조군임상시험
허다희,백형찬,권한슬,김형준,안하영,강소현 대한한방부인과학회 2022 大韓韓方婦人科學會誌 Vol.35 No.4
Objectives: This study was conducted to evaluate the effectiveness of acupuncture in patients with primary menstrual difficulties taking NSAIDs. Methods: 30 women with primary menstrual difficulties with NSAIDs were assigned to treatment groups (n=15) and control groups (n=15). On their first visit, both groups were provided with a menstrual diary and were required to record the intensity of pain and the dosage of painkillers during each menstrual cycle. The treatment group received two acupuncture treatments per cycle during two cycles, and the control group did not receive acupuncture. Pain strength during menstruation was evaluated using Visual Analogue Scale (VAS), and the total number of painkillers taken during menstruation and the average number of painkillers taken during a single dose was measured. Results: The treatment group had significant pain relief compared to the pre-test group and significant differences from the control group. In addition, there was a significant difference between the treatment group and the control group in the frequency of taking painkillers during the menstrual period and the dose in the test group was significantly lower than before treatment. Conclusions: This clinical trial showed that this acupuncture can help alleviate primary menstruation and reduce the use of nonsteroidal anti-inflammatory drugs.
