Hyun Jung Koo,Hye Jung Park,Geun-Young Park,Yeonjae Han,Donggyun Sohn,Sun Im 대한재활의학회 2019 Annals of Rehabilitation Medicine Vol.43 No.6

Objective To determine the location of the motor endplate zones (MoEPs) for the three heads of the triceps brachii muscles during cadaveric dissection and estimate the safe injection zone using ultrasonography. Methods We studied 12 upper limbs of 6 fresh cadavers obtained from body donations to the medical school anatomy institution in Seoul, Korea. The locations of MoEPs were expressed as the percentage ratio of the vertical distance from the posterior acromion angle to the midpoint of the olecranon process. By using the same reference line as that used for cadaveric dissection, the safe injection zone away from the neurovascular bundle was identified in 6 healthy volunteers via ultrasonography. We identified the neurovascular bundle and its location with respect to the distal end of the humerus and measured its depth from the skin surface. Results The MoEPs for the long, lateral, and medial heads were located at a median of 43.8%, 54.8%, and 60.4% of the length of the reference line in cadaver dissection. The safe injection zone of the medial head MoEPs corresponded to a depth of approximately 3.5 cm from the skin surface and 1.4 cm away from the humerus, as determined by sonography. Conclusion Correct identification of the motor points for each head of the triceps brachii would increase the precision and efficacy of motor point injections to manage elbow extensor spasticity.

Yeonjae Lee,Ryan Kang,Jenna Kwon,Kyuhee Jo,Jungbin Im,Sangwook Jung,DongHyun Lee,Juhyeon Lee,Jeong-Sang Lee 한국인터넷방송통신학회 2018 Journal of Advanced Smart Convergence Vol.7 No.2

Celiac disease (CD) is an immune-mediated enteropathy of small intestine diagnosed in both childhood and adulthood. CD is caused by gluten, which produces gliadorphin during its digestion. The enzyme dipeptidyl peptidase-4 (DPP4) breaks gliadorphin down nevertheless the last tripeptide remains and eventually inhibits DPP4, thus slowing down its process. Therefore, the idea is to produce an additional DPP4 enzyme which is crucial. Consequently, the functional DPP4 gene was cloned into pCDNA3 intermediate (FLAG+DPP4) vector and finally a recombinant plasmid pSB1C3 (Andersons promoters+ FLAG+DPP4) was constructed using synthetic biology. Normally, a DPP4 inhibitor is used as a cure for diabetes. Another important concern was overexpression of DPP4, which might lead to diabetes, accordingly the work was also performed for the regulation of the DPP4 gene expression. In this regard, three types of Anderson promoters (strong, moderate and weak) were utilized to study the control overexpression. This is the first report of idealistic trial for control the exogenous DPP4 gene-expression by molecular biologic tools.

아로마요법이 스트레스 관련 변인에 미치는 효과에 대한 메타분석

강현미 ( Hyunmi Kang ),정연자 ( Yeonja Jung ) 사단법인 아시아문화학술원 2020 인문사회 21 Vol.11 No.3

최근 현대인들이 겪는 만성적 스트레스가 심각해짐에 따라 건강을 예방·치유하기 위한 대체요법으로 아로마테라피에 대한 관심이 증가하고 있는 바, 아로마요법이 스트레스에 미치는 개별 연구물들을 바탕으로 통합적인 결과를 도출하여 치유를 위한 체계적 근거를 마련하는데 목적이 있다. 이에 본 연구에서는 2000년 1월-2017년 12월까지 수행 된 아로마테라피와 스트레스 변인과 관련한 연구 논문 129편을 기반으로 R프로그램의 ‘metafor’ package을 활용하여 메타분석을 실시하였다. 그 결과, 아로마요법이 스트레스에 미치는 효과에 대한 사례 수는 총 508개, 전체 효과크기가 0.394로 중 간 정도의 효과크기가 나타났고, 그에 따른 전체 38가지의 하위변인에서 정신적 스트레스가 -1.49로 다른 변인에 비해 가장 큰 효과크기를 가진 것으로 분석되었다. 본 연구는 정신적(심리적) 완화를 위한 대체요법을 발견했다는 데 그 의의가 있다. 한편, 한계점으로 병리, 의학, 건강에 접목한 다각적 연구가 부족했다는 점이다. 향후 연구에서는 융합적 접근을 통해 다양한 변인을 추가하여 연구를 진행해보고자 한다. Recently, as the chronic stress of modern people has become serious, interest in aromatherapy has been increasing as an alternative therapy to prevent and heal health. As a result, treatment has been developed based on individual studies of aromatherapy on stress. The purpose is to prepare a systematic basis for. Therefore, in this study, meta-analysis was conducted using the ‘metafor’ package of the R program based on 129 papers related to aromatherapy and stress variables conducted from Jan. 2000 to Dec. 2017. As a result, the total number of cases for the effect of aromatherapy on stress was 508, and the overall effect size was -0.394, showing a moderate effect size, and the mental stress was -1.49 in all 38 sub-variants. It was analyzed to have the largest effect size compared to other variables. This study is significant because it has found alternative therapies for mental (psychological) relief. On the other hand, the limitation was that there was a lack of multi-faceted studies incorporating pathology, medicine, and health. In the future research, we intend to proceed with research by adding various variables through a convergent approach.

Cho Soo Im,Ko Jung-In,Kim Yeonjae,Yeo Woonhyung,Lee Kangeui,Cho Wonjin,Moon Sungwoo,Park Taejin 대한감염학회 2021 Infection and Chemotherapy Vol.53 No.1

Background: According to the recent coronavirus disease 2019 (COVID-19) pandemic experience, many emergency departments experience difficulties in responding to emerging infectious diseases and this has led to a public health crisis. Our emergency department (ED) is designed to respond to mass outbreaks of infection. Three major preparations were taken to respond to infectious disease; first, to improve the emergency department facilities; second, to created programs to respond to each phase of an epidemic of COVID-19; lastly, to implemented education and training to promote the safety of medical staff. We would like to share the actual responses and statistics of patients visiting emergency department during COVID-19 periods of pandemic. Materials and Methods: This research was conducted through a retrospective chart analysis provided by a public medical center with 502 beds since the first report of a COVID-19 confirmed case on January 19, 2020 to June 15, 2020 in Seoul, the capital of Korea. Our emergency department was designed based on Korean Regional Emergency Center Facility Standards, and modified throughout each phases of COVID-19 outbreak. Patients suspected to be infectious are screened in the triage, separating them from general patients, and then receive isolation treatment in isolated wards. Results: A total of 4,352 patients visited the ED. 3,202 screenings were conducted with 5 confirmed cases. Another 1,150 patients were treated with general emergent symptoms. There were no problems such as closure of the emergency department or isolation of medical staff while managing COVID-19 confirmed patients. Conclusion: Improving emergency department facilities, create an operational program to respond to each phase of COVID-19 outbreak and implement educational programs enabled large number of screening tests and hospitalization for COVID-19 suspected patients while maintaining general medical services. Research in emergency department designs and operational programs should increase to combine research data with better ideas to respond not only during regular periods but also during periods of pandemic.

본 연구에서는 이주여성을 위한 뷰티문화융합 교육을 현장에 적용함으로써 이에 도출된 결과를 분석하여 뷰티문화융합 교육의 실현가능성을 검증하였다. 이에 본 연구자는 이주여성의 심리적 안녕감 증진을 위한 뷰티융합문화교육을 운영하였으며 이를 통해 이주여성의 행복감과 안녕감의 감정정화를 돕고자 하였다. 연구의 방법은 이론적 배경을 통하여 디아스포라 여성의 심리적 특성과 학습특성을 파악하였으며 심리적 안녕감과 구성요인을 고찰하였다. 또한 이주여성 대상의 수요조사를 실시하여 현장에서 필요로 하는 실질적 교육활동 내용을 도출 하였다. 따라서 뷰티의 영역을 바탕으로 도출된 뷰티문화융합 교육은 이주여성의 심리적 안녕감을 향상시키고 이들의 슬픔이나 부정적 감정의 극복과 회복할 수 있는 마음자세를 취하게 함에 긍정적 효과가 있음이 확인되었다. 이는 치유적인 관점으로의 뷰티행동을 활용한 문화융합교육 개발에 기초적 자료로 활용됨에 의의가 있으며 향후 열린사회시대의 새로운 융합치유 프로그램 도출에 있어 뷰티 영역의 메이크업, 헤어, 네일, 피부, 이미지 메이킹 등 세분화, 전문화된 개별적 뷰티영역과 문화교육의 융합으로의 심화연구를 기대한다. In this study, the results of the application of beauty culture convergence education for migrant women were analyzed to verify the feasibility of beauty culture convergence education. The researcher implemented beauty convergence culture education to promote psychological well-being among migrant women. Based on the theoretical background, the research method identified psychological and learning characteristics among women in the diaspora, examining psychological well-being and its components. In addition, a demand survey was conducted on migrant women to determine the actual educational activities that are needed at the site. This study has confirmed that beauty culture convergence education, which is derived from the general area of beauty, had a positive effect, leading to a significant improvement in migrant women’s psychological well-being, especially considering that a positive mental attitude is required to overcome and recover from the sadness and other negative emotions that migrant women face. This is meaningful because it can be used as basic material for the development of cultural convergence education, in particular, the application of beauty behavior to healing. In the future, in order to create new convergence healing programs, we look forward to further studies on the convergence of specialized individual beauty areas and cultural education, including makeup, hair, nail, skin, and image making.
