Objectives The purpose of this study is to analyze the current status of measurement instruments used to evaluate pain and function for shoulder disease patients in Korean Medicine clinical studies published in South Korea. Methods 5 Korean online databases from January 2007 to July 2017 were used to source articles for the review. Data of pain and function assessment instruments, measurement methods, time point and frequency for shoulder assessment were extracted. And it was analyzed by investigating the frequency of use for each item. Results A total of 78 studies met the selection criteria. There were many studies with no description for pain assessment instruments or inconsistent measurement methods. In the function assessment, the frequency of use was low and there were a lot of use of instruments with low validity and reliability. Conclusions To develop the objectivity of clinical research, further clinical studies, active use of measurement instruments, and standardization of measurement methods are needed.

Background: Breast cancer is one of the most common cancers in women in the world. Health-related quality of life (HRQL) at treatment endpoint in cancer clinical trials is widely considered to be increasingly important. The aim of this review was to provide a literature-based assessment of the validity, reliability and responsiveness of breast cancer-specific HRQL instruments in women breast cancer patients. Materials and Methods: The databases consulted were Medline, PubMed, and Embase. The inclusion criteria required studies to: (1) involve use of HRQL measures; (2) cover women with breast cancer under standard treatment (surgery, radiation therapy, chemotherapy, hormone therapy, and targeted therapy); (3) involve the validity, reliability, or responsiveness of HRQL; (4) deal with validation of breast cancer-specific HRQL instruments. Results: A total of 16 studies were identified through the literature search that met the 4 inclusion criteria. Some seven instruments were assessed among these 16 studies: EORTC QLQ-BR23, FACT-B, FACT-ES, HFRDIS, LSQ-32, QLICP-BR, and SLDS-BC. EORTC QLQ-BR23, FACT-B, LSQ-32, QLICP-BR, and SLDS-BC are more general breast cancer-specific HRQL instruments. FACT-EB is the endocrine subscale combined with FACT-B in order to measure the side effects and putative benefits of hormonal treatment administered in breast cancer patients. HFRDIS is the HRQL measure focusing on hot flash concerns. Conclusions: This paper provides an overall understanding on the currently available breast cancer-specific HRQL instruments in women breast cancer patients.

국부적 근 피로는 근전도 신호의 저주파역으로의 천이, 특히 중앙주파수의 감소로 특징된다. 여러 운동각도(0$^{\circ}$, 12$^{\circ}$, 36$^{\circ}$, 72$^{\circ}$)에서 등척성 요추신전운동을 수행하는 동안 근 피로에 따른 근전도 신호의 중앙주파수와 토크의 특성을 살펴보고자 총 20명 (평균 연령 24.35$\pm$2.70세)의 건강i한 피검자를 대상으로 본 실험연구를 수행하였다. 근전도 신호로부터 FFT를 사용하여 중앙주파수를 추출하였으며 선형회귀분석을 통해서 시간에 따른 초기중앙주파수의 초기값과 기울기를 계산하였다. 중앙주파수의 기울기와 토크의 기울기에 대한 상관관계를 정량화하기 위해서 피어슨 상관계수를 적용하였다 중앙주파수의 기울기(p〈0.656)나 v-절편(p〈0.609), 피로지수(p〈0.555)에서는 요추의 각도 타이에 영향을 받지 않아 유의한 차이가 없었으며. 토크의 기울기. 피로지수 역시 유의한 차이가 없었으나, 토크의 ｙ-절편에서는 차이(p〈0.04)가 나타나서, 근육의 길이 증가와 자세변화가 토크에 영향을 미침을 알 수 있었다. 또한, 개인간의 중앙주파수와 토크의 기울기에는 상관관계가 낮았으나, 개인 내에서 중앙주파수와 토크의 시계열 변화에는 유의한 상관관계(0.682)가 있음을 알 수 있었다.

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.

Background: Video-assisted thoracoscopic surgery (VATS) is recognized as a safe and effective treatment modality for early-stage lung cancer and anterior mediastinal masses. Recently, novel articulating instruments have been developed and introduced to endoscopic surgery. Here, we share our early experiences with VATS major pulmonary resection and thymectomy performed using ArtiSential articulating instruments. Methods: At the Seoul Metropolitan Government-Seoul National University Boramae Medical Center, 500 patients underwent VATS pulmonary resection between July 2020 and April 2023, while 43 patients underwent VATS thymectomy between January 2020 and April 2023. After exclusion, 224 patients were enrolled for VATS major pulmonary resection, and 38 were enrolled for VATS thymectomy. ArtiSential forceps were utilized in 35 of the 224 patients undergoing pulmonary resection and in 12 of the 38 individuals undergoing thymectomy. Early clinical outcomes were retrospectively analyzed. Results: No significant differences were observed in sex, age, surgical approach, operation time, histological diagnosis, or additional procedures between the patients who underwent surgery using novel articulating instruments and the group treated with conventional endoscopic instruments for both VATS major pulmonary resection and thymectomy. However, the use of the novel articulating endoscopic forceps was associated with a significantly larger number of dissected lymph nodes (p=0.028) and lower estimated blood loss (p=0.009) in VATS major pulmonary resection. Conclusion: Major pulmonary resection and thymectomy via VATS using ArtiSential forceps were found to be safe and effective, with early clinical outcomes comparable to established methods. Further research into long-term clinical outcomes and cost-effectiveness is warranted.

The rises of the life index quality together with the medical technology improvement lead to a longer life expectancy. Then a better health care program, especially for elderly, is needed. The common health problems facing those senior citizens are changed from acute diseases to chronic diseases, such as diabetes, hypertension. Then u-Health takes center stage in medical industry. Although u- Health medical device manufacturers have been improving their instruments, these instruments still rely on proprietary technologies without fixed platform. Even if the interface has been provided by the manufacturer, there is no widely-accepted uniform data model to access data of various u-Health devices. IEEE 11073 is a standard attempting to unify the interfaces of all medical devices. In this paper we have proposed a conversion software platform that assures interoperability among medical devices for ubiquitous sensor network. This module uses in order to develop a standard platform of medical system.

Using computational fluid dynamics with the fluid-structure interaction, structural effects of intra-luminal thrombus were determined in thrombosed axisymmetric abdominal aorta aneurysm (AAA) models under pulsatile flow. Four different models, varying dilatations of the aneurysm and Young's moduli of intra-luminal thrombus, were defmed. Compared with unthrombosed AAA models, both von Mises stress and radial displacements in the aneurysm wall significantly decreased. Stiffer intra-luminal thrombus reduced von Mises stress in the aneUtysm wall. The present study supported that intra-luminal thrombus might reduce wall stress in the aneurysm.
