  • In order to understand the phenomenon in a living cell correctly, it has been required to obtain intact responses from the cell membrane without disrupting the cytoplasmic circumstances. Gramicidin perforated patch configuration allows the electrical access to the whole cell with a minimal dialysis of cytoplasm and preventing the loss of native intracellular constituents, such as $Cl^-.$ Here, we would like to show the background of this method and the actual application of the gramicidin perforated patch recording mode on the dissociated neurons.

  • Evoked potentials(EP) measured with scalp electrodes are often described as a deterministic process corrupted by uncorrelated electrical activities occuring in the brain and These electrical activities(ongoing EEG) refer to noise in EP recording. The Conventional method to determine the EP waveform requires long recording time. Unfortunately most of algorithm developed are too complicated for implementation in real time. Thus, conner EP recording devices use Ensemble average for real time processing. In this paper introduce EP recording hardware for processing advanced algorithm in real tlne. This hardware is composed of DSP chip(TMS320c25) and microcomputer.

  • The Korean government has a new system for charging patient care for patients in hospital, on hold for the present(9 / 1995) but to start implementation in certain areas of patient care next year. From the latter half of next year the Ministry of Health and Welfare would like to start demonstration projects for hospitals who want to start using DRGs for frequently seen medical diagnosis and for patients with a course that is predictable and for whom non-insurance costs are minimal : such as the patient who has a delivery, cesarean deliveries, cataract surgery, tonsillectomy or an appendectomy, and apply the DRG system of payment for hospital care for these patients. The purpose of this study was to establish a recording system to give effective home health care to postpartum women and their newborns. Recently the government announced a DRG system to apply to postpartum women for pilot purposes starting next year. This gives impetus to the need to develop home care records that will allow for systematic recording and provide continuity and consistency in care across all health professionals and with in-depth communication between the professions to assure high quality care. There has been a rise in medical costs and a shortage of patient bed space in hospitals, particularly since the introduction of national medical insurance. The study focused on developing client selection criteria, a primary assessment tool, progress notes and nursing diagnoses applicable to postpartum and newborn clients. Selection criteria for home health care, assessment tool content, nurses progress notes and diagnoses were developed through a review of the literature, advice from professionals who are expert in home health care and actual practice in the use of recording tools through workshops. The recommendations based on the research results are as follows : 1) Replication and application of these tools is needed to test the validity of the tools 2) In order to have systematic nursing records standardization of records has to be done after nurses have had experience using them. 3) Reliability and validity of the tools has to be established through applicability to actual care situation.

  • Purpose: It is crucial that 119 emergency medical technician (EMT) have adequate knowledge regarding forensic science. This study aimed to assess the forensic knowledge of EMTs in the Republic of Korea. Methods: This study was conducted on EMTs of five fire stations in D metropolitan city between August 6 and August 13, 2018. A questionnaire consisting of items on crime-related incident recognition (i.e., mechanical asphyxiation, trauma, sex crimes, and child abuse), forensic evidence management (i.e., evidence collection, preservation, and recording) was administered to the participants. Finally, 119 questionnaires were analyzed. Results: The ratio of correct answers for crime-related incidents recognition was 55.82%, which was lower than that for forensic evidence management(84.5%). In particular, the scores for the type of neck compression(16.5%) and wound assessment(44.0%) were low. The percentage of correct answers for forensic evidence management was 78.4% for evidence collection, 84.4% for evidence preservation, and 90.6% for evidence recording. Previous forensic education experience was not a significant variable. Conclusion: Specific and practical forensic science education on perception of crime-related incident, including asphyxia and wound identification, and forensic evidence collection is needed.

  • Purpose: The purpose of this study was to examine the effects on knowledge and performance in clinical nurses who participated in education on nursing recording focusing on the legal aspects. Method: The participants were working in medical departments in one hospital. There were 32 nurses in the experimental group and 25 in the control group. Pre-test was conducted on the two groups before education, and, in order to examine the effects of education, a post-test was conducted after three weeks. For the experimental group, the education on nursing recording focusing on legal aspects was provided as a lecture-led one-to-one training. Results: Significant differences were found between the experimental and control groups in knowledge (F=15.728, p<.001), and performance (F=42.454, p<.001). Conclusions: The results of this study indicate that education on nurse recording enhances the knowledge and performance of the nurses. Thus education on nurse recording focusing on legal aspects should be required in the area of nursing science.

  • An account book of medical treatment is a form of collection materials for diagnostic standardization, and it is a basis of standardization, standardization of medical records is a preconsideration of each standardization. But an account book of medical treatment is only a kind of form for recording medical treatment, therefore standardization of medical treatment eventually holds the key to the standardization of recording charts. However until now we have gradually reformed medical records in accordance with individual characters of medical treatment, and didn't have even standard sheme of medical records, also medical terms for medical records had an inconsistency of redescription and reiterative representation for an identical terms in all parts of the East learning, medical terms for medical records didn't unity. To make better this realities, standardization study used orginated system in the process of existing study, it can get ready the basis of discussion between O.M.D and O.M.D. it can make analysis of diagnostic course and can clearly understand usable information by diagnostic course. for that reason we hope that the basis of standardization is accomplished. And in advance of study for this standardization we have to analysis the course of medical treatment with demonstration of roof, first of all we have to study term definition by diagnostic course and prepare basis by diagnostic course. because this study have limits of indivisual study, it needs to long and synthetic investigation in Association levels. Although we cann't completely alternate with methods of measurement which relyed on individual mastery, if we exclude erroes of individual measurement through mechanization and verify results of diagnosis through keynotes, we can realize standardization of medical treatment with demonstration of proof and in this process we can use medical records as a tool collecting exact data, also we can realize standardization of drawing up medical records.

  • 망막의 신경절세포는 눈에 가해진 시각 정보를 흥분파의 형태로 변환하여 시신경을 통하여 대뇌의 시각피질까지 전달한다. 과거에 사용하여 왔던 방법은 단일 전극을 단일 뉴론의 세포내, 외에 삽입함으로써 특정 시간대에 특정 뉴론만을 기록하는 방법이었으므로 신경망 전체를 통하여 처리되어 나오는 정보를 알아보기에는 적합하지 않다. 다행히 최근에 다채널 전극을 사용하여 여러 신경세포에서 나오는 신호를 동시에 기록할 수 있는 다채널기록법(multichannel recording) 이 개발되었으므로 본 연구에서는 8행 ${\times}$ 8열의 다채널전극을 사용한 다채널기록법을 이용하여 망막신경절세포 군집의 흥분파를 기록, 분석함으로써 단일 신경세포가 아닌 망막 신경망을 거쳐 최종적으로 나오는 신호에 대해서 연구하였다. 전극에 부착된 망막 절편에 2초 동안 빛을 가하고 5초 동안 빛이 차단되는 자극을 반복적으로 인가한 후, PSTH 분석방법으로 망막 신경절세포를 ON 세포, OFF세포, ON/OFF세포의 세가지 유형으로 분류할 수 있었으며, ON 세포: 35.0$\pm$4.4%, OFF 세포: 30.4$\pm$1.9%, ON/OFF 세포: 34.6$\pm$5.3% (전체 망막절편수=8)로 분포되어 있음을 확인하였다. 또한 상호상관(Cross-Correlation) 분석방법을 통해서 인접한 세포들끼리 매우 짧은 시간대에(<1 ms) 동기화된 흥분을 발사함을 확인할 수 있었고, 동기화된 흥분은 6~8개의 세포로 구성된 세포 클러스터에서 일어남을 확인하였다. 즉 개개의 신경절세포들이 빛 자극을 처리함에 있어 독립적으로 작용한다는 기존의 가정과는 달리 인접한 세포끼리는 동기화된 흥분을 보이는 것을 확인하였으며, 이러한 방식은 시세포 수와 신경절세포 수의 불균형으로 인해 초래되는 병목현상을 완화할 수 있는 효과적인 기전으로 생각된다.

  • Adverse drug reactions (ADRs) constitute key factors in determining successful medication therapy in clinical situations. Integrative analysis of electronic medical record (EMR) data and use of proper analytical tools are requisite to conduct retrospective surveillance of clinical decisions on medications. Thus, we suggest that electronic medical recording and human genetic databases are considered together in future directions of pharmacovigilance. We analyzed EMR-based ADR studies indexed on PubMed during the period from 2005 to 2017 and retrospectively acquired 1161 (29.6%) articles describing drug-induced adverse reactions (e.g., liver, kidney, nervous system, immune system, and inflammatory responses). Of them, only 102 (8.79%) articles contained useful information to detect or predict ADRs in the context of clinical medication alerts. Since insufficiency of EMR datasets and their improper analyses may provide false warnings on clinical decision, efforts should be made to overcome possible problems on data-mining, analysis, statistics, and standardization. Thus, we address the characteristics and limitations on retrospective EMR database studies in hospital settings. Since gene expression and genetic variations among individuals impact ADRs, pharmacokinetics, and pharmacodynamics, appropriate paths for pharmacovigilance may be optimized using suitable databases available in public domain (e.g., genome-wide association studies (GWAS), non-coding RNAs, microRNAs, proteomics, and genetic variations), novel targets, and biomarkers. These efforts with new validated biomarker analyses would be of help to repurpose clinical and translational research infrastructure and ultimately future personalized therapy considering ADRs.

  • The performance of electroencephalogram (EEG) recordings is affected by electrode type, electronic parameters such as filtering, amplification, signal conversion, data storage; and environmental conditions. However, no single method has been identified for optimal EEG recording quality in all situations. Therefore, we aimed to provide general principles for EEG electrode selection as well as electronic noise reduction, and to present comprehensive information regarding the acquisition of satisfactory EEG signals. The standards provided in this document may be regarded as Korean guidelines for the clinical recording of EEG data. The equipment, types and nomenclature of electrodes, and the details for EEG recording are discussed.
