The purpose of this study was to develop a wearable platform system that can detect and acquire a soldier’s biosignals (i.e., heart activity signal, respiration rate, etc.) in a nonrestrained, unconscious manner. These detected biosignals are transmitted to a processing device to analyze and monitor the soldier’s physical status. To achieve this, textile-based heart activity electrodes and a strain gauge sensor for the respiration signal measurement were developed, and their performances in detecting each signal were verifed. These sensors were embedded in a chest belt to design a wearable platform that can simultaneously measure heart activity and respiration signals. The sensor part of the chest belt has a dual layer structure to detect high-quality signals. Stretch fabric was used on the outer layer and a respiration sensor was attached to the belt. On the inside layer, a non-stretch fabric was used as the base fabric and a heart activity-sensing electrode, that is capable of taking measurements using a modifed lead-II heart activity signal induction method, was embroidered onto the fabric. Subjects were asked to wear the chest belt, and a biosignal processor module was attached to verify the system’s performance while simultaneously acquiring the heart activity and respiration signals. More specifcally, it was confrmed that the two signals were detected in a stable. It is expected that the biosignal-monitoring wearable platform system developed in this study will be able to efectively analyze and monitor soldiers’ biosignals.

신규간호사의 능력은 간호학생 때의 다양한 임상경험에 기초를 둔다. 따라서, 간호대학의 교수, 병원 지도자, 임상지도자는 간호학생들이 다양한 지식을 획득하고 간호기술을 경험할 수 있도록 도와주는 중요한 역할을 한다. 이 연구의 목적은 이러한 간호학생들의 임상실습에서 수행하는 간호활동과 간호활동 시간을 분석하고자 하는데 있다. 연구결과 간호학생 1인당 직접간호활동 시간은 185.5분(직접간호비율은 56.7%)으로 141.65분(간접간호 비율은 43.3%)인 간접간호활동 시간보다 많았다. 직접간호활동 시간 중 활력징후 측정이 51.9분으로 가장 많은 시간을 차지하였고, 간접간호활동 시간 중에는 차트보기가 22.98분으로 가장 많은 시간을 차지하였다. 전반적으로 기본적인 임상간호 수행기술에 소요되는 시간이 고도의 숙련된 간호기술을 수행하는데 드는 시간보다 많은 것으로 나타났다. 따라서, 본 연구결과를 토대로 간호대학의 지도자와 병원의 지도자 및 임상지도자가 함께 임상실습 교육과정의 지침서와 평가서를 평가할 필요가 있다고 제언하는 바이다. The competence of newly graduated nurses is based on various clinical experiences gained when they were students. Therefore, professors in nursing schools, directors in hospitals or preceptors must play a critical role in assisting them to obtain various knowledge and experienced nursing skills. The purpose of this study is to investigate nursing care activities and nursing care hours practiced by nursing students in clinical experience. The results of this study showed that the direct nursing care hours per each nursing student are 185.5 mins(direct nursing care rate 56.7%) and it is higher than indirect nursing care hours, 141.65 mins(indirect nursing care rate 43.3%). The hours of checking vital signs are the longest(51.9mins) among the direct nursing care activities, and the hours of reviewing chart are the longest(22.98mins) among the indirect nursing care activities. In general, the time of performing basic clinical nursing technique was higher than that of performing high skilled nursing technique. And nursing observation was higher than that of directly performing task. So, we suggest based on the results of this study as follows. It is needed for nursing instructors in nursing schools and hospitals together to evaluate the guidelines and check-list of clinical practice courses.

임상실습 교육은 간호이론을 실무에 적용하는 기회를 제공하는 과정으로서 임상실습이 간호교육의 중요한비중을 차지하고 있다는 것은 주지의 사실이다. 이러한 중요성에도 불구하고, 임상실습 교육에 즉각적인 해결이 어려운 많은 문제점이 있음도 이미 알고 있는 사실이다 이에 임상실습 교육의 기초 자료로 활용되고 있는 실습목록표에 대한 간호 학생들의 실습목표의 명확한 이해와 더불어 이론과 실습의 연계성을 강화시키고자 하였다. 성인간호, 모성간호, 이동간호 3개 영역 모두에서 공통적으로 기본임상간호 항목이나 기본간호술과 관련된 항목에서 직접수행의 빈도가 높았고 숙련된 기술적인 처치나 전문성을 필요로 하는 항목에서는 관찰과 수행경험이 부족한 것으로 나타났다. Clinical performance is not only the process of providing the opportunity for applying nursing theory into practice but also it is a well-known fact that clinical performance is an important part in nursing education. lnspite of this importance, it is also true that many problem with no immediate solution exist in clinical performance of nursing students. thus, through measuring and analyzing the degree of clinical experience of the nursing students, on the nursing checklist that is being used as the basic guide in clinical education, we tried to clearly understand the objectives of clinical performance and to emphasize the connection between theory and clinical performance. The results of the study showed that the frequency of directly performing tasks was high in all areas of adult health nursing, maternity nursing, and child nursing for the items of basics clinical nursing and items related with basic nursing techniques, and that the experiences of observation and execution were lacking in the items needing skilled treatment or speciality.

Schwann cells(SCs), an important component of the peripheral nervous system, intract with nerous to mutually support growth and replication for the peripheral nerve regentation. Recently, ading SCs to the lumen of guidance channel is widely tried to improve regeneration or to make regeneration possible over otherwise irreparable gaps. however, it is not easy to isolate and multiplicate SCs as much as enough to help the axonal regeneration. For the allogeneic SCs source for tubular nerve guidance, we developed a little bit improved technique of harvesting and multiplicating SCs. by culturing dispersed dorsal root ganglia in specially designed medium with growth factors and serial processing, we repeatedlly generate relatively homogenous SC cultures. Our technique was compared with other methods of literature using immunostaining methods such as GFAP, S100, BDNF and the total SC count assessment at different time interval after primary culture.

본 연구에서는 배의 유용성 증명을 위한 일환으로 배의 화학성분을 분자수준에서 밝히고자 하였다. 이에 배 과피 MeOH 추출물을 용매분획하여 얻은 EtOAc-산성 분획과 EtOAc-중성분획을 대상으로 Sephadex LH-20, silica gel, 그리고 ODS colmn chromatography와 HPLC를 이용하여 정제 및 단리하였다. 그 결과, EtOAc-산성 분획과 EtOAc-중성 분획으로부터 각각 2종씩의 화합물을 단리하였다. 단리된 화합물 1-4는 1H- 및 13C-NMR 분석을 통하여 각각 (S)-(+)-2-cis-abscisic acid O-β-D-glucopyranosyl ester (화합물 1), 1-[4-O-β-D-glucopyranosyl]phenyl ethanone(piceoside, 화합물 2), β-sitosterol (화합물 3), 그리고 β-sitosteryl 3-O-β-D-glucopyranoside (화합물 4)로 동정되었다. 단리된 3종의 배당체 화합물(화합물 1, 2, 4)들은 본 연구에 의해 배로부터 처음 동정되었으며, 화합물 3은 추황배로부터 처음 동정되었다. 본 연구결과가 배 함유 성분연구는 물론 배의 기능성 해명 연구에도 추후 중요한 기초자료로 활용되길 기대한다. We isolated and identified antioxidants from acidic and neutral ethyl acetate fractions of the peel of pear (Pyrus pyrifolia N. cv. Chuhwangbae). We isolated 4 compounds from the methanol extract, by using 3 different types of column chromatography (Sephadex LH-20, silica gel, and octadecylsilane) and preparative HPLC. We identified the isolated compounds as (S)-(+)-2-cis-abscisic acid O-β-D-glucopyranosyl ester (compound 1), 1-[4-O-β-D-glucopyranosyl]phenyl ethanone (picroside, compound 2), β-sitosterol (compound 3), and β-sitosteryl 3-O-β-D-glucopyranoside (compound 4) by nuclear magnetic resonance analysis. We are the first to report the identification of compounds 1, 2, and 4 from pear.
