Purpose: The purpose of this study was to develop an assistant device for the promotion of bag-valve-mask ventilation based on a non-equivalent control group pre-test and post-test design. Methods: The experimental tool was a mask assistance device developed by the researchers. Data were analyzed using SPSS 21.0 with the cardiopulmonary resuscitation (CPR) evaluation program from August 18 to 30, 2016. The research tools included general, hand-related, and ventilation-related characteristics. Results: Before and after using the mask assistance device, the tidal volume increased by 64 mL (p<.001) from 461.76 mL to 525.86 mL. The tidal volume for control was 477.86 mL, and there was a statistical difference (p<.05). The ventilation frequency in device users was 10 times per minute for a total of 20 ventilations with before 10.65 after 10 times, and that of the control group was before 10.36 times after 10 times; there was no difference in both groups(p>.05). The accuracy of the assistance device was $81.72{\pm}30.86%$, which was a very high value. However, the accuracy of ventilation in the control group with no assistance device was $18.97{\pm}32.44%$, which was a very low accuracy rate. Conclusion: This study's results suggested utilizing the newly-developed mask assistance device in CPR, and showed increases in tidal volume and accuracy of ventilation using the bag-valve-mask ventilation equipment. The general and hand-related characteristics did not have any effect, so the use of the device proved to increase the efficacy in all users.

Background/Objectives: The purpose of the study is to present scenarios in which sudden cardiac arrest occurred in adults to find out the result of the hands only chest compression and how to chest compression with the foot and to suggest the direction of CPR education for children based on the results. Methods/Statistical analysis: 39 pre-schoolers who did not receive any training related to CPR were selected as subjects and randomly as a group that compression using their hands and a group that compression using their feet. Statistical analysis was performed using the SPSS for Window 21.0(SPSS INC., Chicago, IL, USA) program, using descriptive statistics for general characteristics, and independent t-test for each variable of study results during chest compressions. All statistical analyzes acknowledged that the p-value was less than 0.05 as statistically significant. Findings: There was no statistically significant difference between the two groups the compression depth, the compression rate, the incorrect of compression rate, the weakness compression but the number of insufficient relaxation was statistically significant between the two groups. When educating and promoting CPR in children, it is recommended to teach systematically how to quickly recognize cardiac arrest situations and how to quickly activate the emergency medical system.

권찬양,양현모 한국엔터테인먼트산업학회 2023 한국엔터테인먼트산업학회논문지 Vol.17 No.8

This study is a qualitative study that seeks to explore the experiences and difficulties of paramedical students who participated in Cadaver anatomy observation. The subjects were 10 first-year paramedical students at a university located in C city. The study identified four categories and eleven subcategories as results. Students reported experiencing contrasting emotions when first encountering the cadaver and feeling unfamiliar with the formalin odor and cold temperature. However, as the education progressed, they shared that the experience of understanding the morphological structure through Cadaver anatomy observation was unforgettable. They expressed a deep sense of mission and a desire for excellence in their future roles as paramedic through the Cadaver anatomy observation. This research is expected to contribute to understanding the physical and psychological responses that paramedical students may experience during Cadaver anatomy observation. Consequently, it can serve as foundational material for developing coping strategies for stress during anatomy lab sessions, enhancing ethical awareness, and exploring values as future paramedics

국내 시신기증절차를 경험한 유가족의 연구가 없는 실정에서 본 연구는 충북대학교 의과대학에 시신기증을 한 유가족 10가정을 대상으로 기증 당시의 경험을 현상학적으로 분석하였다. 연구에 참여한 유가족들은 내 가족의 시신을 기증하게 될 줄 몰랐다고 답하였으며 기증인의 오랜 설득에 동의하였고 유가족들의 종교 및 가치관 등이 영향을 미쳤다고 답하였다. 기증절차를 이행하는 당시에는 기증 시신의 상태를 확인하는 예상치 못한 질문에 당황하였고 시신 인도 절차와 장례가 겹쳐져 불편하였으며 기증절차가 순식간에 끝나서 허무하였다고 답하였다. 납골당 안치 후 유가족들은 기증인의 희생과 헌신을 기리며 사람들이 함께 기증인의 뜻을 기릴 수 있는 지원이 있기를 바랐으며, 본인 또한 이러한 뜻을 기리기 위해 본인의 시신을 기증할 의사가 있음을 밝혔다. 이전의 연구들을 통해 볼 때 충청북도의 시신기증 서약비율은 안정적인 수준에 올라있음을 알 수 있으나, 향후 서약한 기증 예정인이 실제 기증으로 이어질 수 있도록 기증에 대한 최종 의사결정권을 가지고 있는 유가족에게 기증에 대한 인식의 제고와 시신기증 홍보 및 안내방안 그리고 이와 관련한 시신기증데이터의 통합관리 시스템의 구축 등이 실질적으로 이루어져야 할 것이다. Since there is no research on bereaved families who have experienced the body donation process in South Korea, this study phenomenologically analyzed the experiences of 10 bereaved families who donated their family body to Chungbuk National University College of Medicine. These families revealed that although they did not initially intend to donate the remains of their loved ones, their decision was influenced by the deceased’s persistent persuasion and their own religious and value-based beliefs. During the donation process, they were taken aback by unexpected questions about the condition of the donor’s body, felt inconvenienced as the body handover process coincided with the funeral, and expressed a sense of emptiness as the donation process concluded in an instant. After the donation was completed, the bereaved family expressed their intention to donate their own body along with the donor’s, wanting to commemorate the donor’s sacrifice and dedication with many others. In order to enable those who have pledged to donate their bodies to actually donate their bodies in the future, it is necessary to educate, promote, and provide guidance to bereaved families and each university that has the final decision-making authority on donation. Additionally, an integrated body donation management system need to be established.

시신기증을 통한 해부학교육의 중요성에도 불구하고, 국내 시신기증자의 인구학적 특성에 대한 자료는 여전히 부족하다. 이 연구는 충청북도 내 사망자와 기증자의 인구학적 특성을 조사하고자 하였다. 2008년부터 2021년까지 충북대학교 시신기증자 151명, 충청북도 사망자 149,487명을 대상으로 하였으며, 조사 항목은 총 수, 연령, 성별, 사망원인, 사망장소 등이었다. 기증자의 수는, 2008년 13명에서 2021년 22명으로 1.7배 증가하였다. 기증자 중 남성 63.6%, 여성은 36.4%였고, 나이는 70대 30.5%, 80대 29.8%, 60대 18.5% 순이었다. 기증자의 거주지역은 청주시 76.2%, 증평군과 진천군이 각각 4.6%였고, 사망원인은 신생물 23.2%, 달리 분류되지 않은 증상 21.2%, 호흡계통의 질환 19.2% 순이었다. 사망장소는 병•의원이 70.2%로 가장 많았다. 이 결과는 의학교육과 연구에 필수적인 시신기증에 대한 긍정적 효과와 필요성을 알리기 위한 홍보 및 국내 시신기증 활성화를 위한 일원화된 관리 체계가 마련되는 데 주요한 기초자료로 활용될 수 있을 것이다. Despite the significant importance of anatomy education facilitated by anatomical gifts, there remains death of data concerning the demographic characteristics of domestic body donors in Korea. This study aims to compare the demographic features, including death count, age, gender, causes of death, and location, by analyzing a database comprising 149,487 deceased individuals from Chungcheongbuk-do and 151 anatomical gift donors from Chungbuk National University Medical School spanning the years 2008 to 2021. Notably, the number of donated cadavers has seen a 1.7% increase, rising from 13 in 2008 to 22 in 2021. Among the donors, males accounted for 63.6%, while females constituted 36.4%. In terms of age distribution, the 70s represented 30.5%, followed by the 80s at 29.8%, and the 60s at 18.5%. Notably, the region with the highest proportion of donors was Chungju city among the six analyzed regions. Leading causes of death among donors included neoplasms (23.2%), unspecified clinical and laboratory findings (21.2%), and respiratory system diseases (19.2%). Hospitals were the predominant location of death for donors, accounting for 70.2%. These results are expected to serve as essential foundational data for education and research endeavors pertaining to anatomical gifts in Korea. Moreover, it is our hope that a comprehensive management system will be established to further foster anatomical gift donation in the country.

김찬양(Kim, Chan-Yang),권중원(Kwon, Jung-Woon),이진욱(Lee, Jin-Wook) 한국체육과학회 2021 한국체육과학회지 Vol.30 No.4

The purpose of the current study is to assess the effectiveness of a dynamic neuromuscular stabilization training intervention for sedentary female worker with mechanical neck pain after analyzing neck pain, cervical position angle, and muscle strength. Thirty sedentary female workers were assigned to two experimental groups (dynamic neuromuscular training group, n=16, control group, n=14). The subjects in the dynamic neuromuscular training group were participated for 60 minutes/day and three times/wk for 12 weeks. Whereas subjects in control group were asked to maintain normal lifestyle during the same intervention period. The neck pain, cervical position angle, and muscle strength were measured before and after the twelve-weeks intervention. Study results showed that NRS(p<.001), NDI(p<.001), and CRA(p<.001) were significantly decreased in the dynamic neuromuscular stabilization training group, and CVA(p<.01) and neck flexor(p<.001) were also significantly increased in the dynamic neuromuscular stabilization training group. These findings suggest that dynamic neuromuscular stabilization training may have a positive effect on the neck pain, cervical position angle, and neck flexor in mechanical neck pain.

Purpose: The purpose of the study was to compare the ability of college students to use automated external defibrillators (AED) and to provide a basic data for helping laypersons easily apply the AED. Methods: The subjects were randomly assigned to instruction groups. One group was instructed by pictures (group P), one by videos (group M), and one by telephone dispatchers (group D), Without employing cardiopulmonary resuscitation, a single rescuer was asked to apply defibrillation to a mannequin for practice in accordance with the instructions assigned to each group. Results: Regarding the proper pad attachment of the AED, group P followed the instruction $0.31{\pm}0.47times$, group M, $0.81{\pm}0.40times$, and group D $0.69{\pm}0.47times$. Regarding the instruction of taking the hand off a patient for analyzing cardiac rhythm and the instruction of taking the hand off a patient before defibrillation, group P did not follow the instruction; group M followed the instructions $0.50{\pm}0.51times$; and group D followed all instructions at all times. Conclusion: If a dispatcher gives real-time instructions for using an AED to laypersons wtih no experience at the time of AED use, the quality of laypersons' AED use will greatly improve.

온내장좌우바뀜증 시신의 위세로칸과 목뿌리에서 신경 및 혈관 구조들의 형태 변이

최나래,권찬양,신강재,이민영,손현준,길영천 대한체질인류학회 2023 해부·생물인류학 (Anat Biol Anthropol) Vol.36 No.4

연구목적으로 기증된 63세의 온내장좌우바뀜증 남성 시신의 목뿌리와 위세로칸에 위치한 주요 혈관과 신경들의 국소해부학적 위치관계를 관찰하여 다음과 같이 보고하고자 한다. 속목정맥과 빗장밑정맥이 합쳐져 팔머리정맥을 형성하는 것은 정상적인 형태와 차이가 없었으나 오른쪽 팔머리정맥이 더 길게 형성되어 대동맥활의 앞을 가로질러 왼쪽에 위치한 위대정맥으로 합류하였다. 가슴림프관은 오른쪽 정맥각으로 합류되었다. 대동맥활의 주요 분지순서는 팔머리동맥, 온목동맥, 빗장밑동맥 순으로 정상의 경우와 동일하였으나 첫 번째 가지인 팔머리동맥은 분지된 이후 왼온목동맥과 왼빗장밑동맥으로 분지하였다. 이후 대동맥활에서 순차적으로 분지한 온목동맥과 빗장밑동맥은 오른쪽 목뿌리로 주행하여 오른온목동맥과 오른빗장밑동맥을 형성하였다. 미주신경에서 분지되는 되돌이후두신경 또한 정상적인 주행경로와 비교하여 좌우가 바뀐 대칭의 형태로 오른되돌이후두신경은 대동맥활을, 왼되돌이후두신경은 빗장밑동맥을 감고 후두를 향해 주행하였다. 온내장좌우바뀜증을 가진 환자는 극히 소수에서 나타나는 증례로 임상의가 수술과정에서 신경, 혈관구조들의 해부학적 형태와 위치 관계를 빠르게 파악하는 것이 쉽지 않다. 본 연구에서는 온내장좌우바뀜증을 가진 시신의 목뿌리와 위세로칸에서 신경, 혈관구조들의 국소해부학적 위치 관계를 자세히 제시하고 있기에 온내장좌우바뀜증을 가진 환자의 시술 및 수술과정에서 외과의의 혼란을 줄이고 안전성을 높이는데 도움이 될 것으로 생각된다. This study is the case report for the topographic anatomy of the major blood vessels and nerves located in the cervical root and superior mediastinum of a 63-year-old male cadaver with situs inversus totalis donated for research purposes. The internal jugular vein and subclavian vein combined to form the brachiocephalic vein did not differ from the normal case, but the right brachiocephalic vein was formed longer than the left, and crossed the front of the aortic arch to joined into the superior vena cava. The thoracic duct was joined to the right venous angle. The branching order of the main branches of aortic arch was the same as in the normal case: brachiocephalic artery, common carotid artery, and subclavian artery, but the first branch, the brachiocephalic artery, branched into the left common carotid artery and left subclavian artery after branching. Afterwards, the common carotid artery and subclavian artery, which sequentially branched from the aortic arch, traveled to the right cervical root to form the right common carotid artery and the right subclavian artery. The recurrent laryngeal nerve, which branches off from the vagus nerve, also had a left-right reversed pattern compared to the normal running course. The right recurrent laryngeal nerve wound the aortic arch, and the left recurrent laryngeal nerve wound the left subclavian artery and traveled up toward the larynx. Patients with situs inversus totalis are very rare cases, and it is not easy for clinicians to quickly identify the anatomy and positional relationship of nerve and vascular structures during surgery because it is not a familiar form. This study presents in detail the positional relationships of nerves and vascular structures in the cervical root and superior mediastinum of cadavers with situs inversus totalis, so we think this report will be helpfull reducing confusion for surgeons and improving safety during surgery for patients with situs inversus totalis.
