본 연구의 목적은 온라인과 오프라인 공간에 다양하게 존재하는 지리 관련 학습 자료를 지도를 기반으로 매쉬업한 지리교육사이트를 구현해 봄으로써 지도를 기반으로 한 지리교육의 가능성을 탐색해보고자 하였다. 최근 지오웹환경의 급격한 변화는 지리교육에 있어서도 지도에 기반한 다양한 변화가능성을 제안하고 있지만, 지리교육분야에서 그와 관련된 연구는 매우 제한적이었다. 그러나 본 연구에서는 첫째, 교과서 분석을 통하여 콘텐츠를 설계하고, 그 개념을 설명하기 위한 사진, 영상, 개념도 등 다양한 관련자료를 수집하였으며, 둘째, 수집된 자료를 구글의 오픈 API를 활용하여 지도기반으로 매쉬업하였으며, 셋째, 교과서 분석에 따른 내용분류와 수집된 자료를 바탕으로 지리교육사이트를 구축하였다. 본 연구는 공간을 다루는 지리교육에서 텍스트위주가 아닌 지도기반으로 교육을 할 수 있는 가능성을 탐색하고, 지오웹환경에서 교과서의 다양한 개념을 가장 잘 표현할 수 있는 방안을 모색하였다는데 의의가 있다. The purpose of this research is to explore the possibility of geographic education by implementing the map-based geographic education site which mashed up with Google earth by referring the various materials of geographic education which exist in on-line and off-line. In recent years map-based geographic education is required by the radical change of geoweb environments, but there have been few researches in this field. This research is folded up as follows: First, we designed the contents through the textbook analysis and then collect various data related to the contents such as pictures, video clips, conceptual map, etc. which are required to explain the concept. Second, we mashed up the collected data on the Google earth by using the Google's open API. Third, we implemented the geographic education website based on the classification of contents in textbook and the various collected data. This research is important in both that it explores the possibility of the map-based education rather than the text-based education in the geographic field which handles mainly the space and finds the best method to express the various concepts of the textbook on the geoweb environments.
오염준설토의 중금속 안정화를 위한 Hydrothermal Reaction의 최적 조건 도출
이선주,안현규,조우리,김수희,이재영,Lee Sun-Ju,An Hyeon-Kyu,Cho Woori,Kim Su-Hee,Lee Jai-Young 한국지하수토양환경학회 2024 지하수토양환경 Vol.29 No.1
Hydrothermal Reaction (HTR) was applied for the stabilization of contaminated soil with heavy metals, and then the test determined the optimal conditions for HTR. After HTR, the concentration of heavy metals in the contaminated soil increased. However, it was observed that the leachability potential significantly decreased as determined by TCLP and SPLP tests. This decrease was attributed to a decline in fractions 1-2 and an increase in fractions 3-4 as revealed by sequential extraction procedure. Due to the mineralogical characteristics of the dredged soil, distinct changes were not evident in the five-stage fraction. Therefore, it is deemed necessary to understand the chemical and mineralogical characteristics of the target soil for HTR application in order to selectively address contaminants. Comparison among operating conditions determined the optimal condition to be at 240℃ for one hour.

Purpose: The purpose of this study is to evaluate how university hospital Institutional Review Boards (IRBs) in Korea classify risk when reviewing clinical trial protocols. Methods: IRB experts (IRB chairman, vice chairman, IRB administrator) in the university hospitals obtaining a Human research protection program (HRPP) or IRB accreditation in Korea were asked to fill out the Google Survey from September 1, 2020 to October 10, 2020. Result: Among the 23 responder hospitals, 8 were accredited by the American Association for Human Research Protection Program (AAHRPP) and 8 were accredited by the HRPP of Ministry of Food and Drug Safety (MFDS). Seven were accredited by Forum for Ethical Review Committees in Asia and the Western Pacific or Korea National Institution for Bioethics Policy. Thirteen of 23 hospitals (56.5%) had 4 levels (less than minimal, low, moderate, high risk), 4 hospitals had 3 levels (less than, slightly over, over than minimal risk), 1 hospital had 5 levels (4 levels plus required data safety monitoring board), and 1 hospital had 2 levels (less than, over than minimal risk) risk classification system. Thirteen of 23 hospitals (56.5%) had difficulty classifying the risk levels of research protocols. Fourteen hospitals (60.9%) responded that different standards among hospitals for risk level determination associated with clinical trials will affect the subject protection. Six hospitals (26.1%) responded that it will not. Three hospitals (13.0%) responded that it will affect the beginning of the clinical trial. To resolve differences in standards between hospitals, 14 hospitals (60.9%) responded that either the Korean Association of IRB or MFDS needs to provide a guideline for risk level determination in clinical trials: 5 hospitals (21.7%) responded education for IRB members and researchers is needed; 3 hospitals (13.0%) responded that difference among institutions needs to be acknowledged; and 1 hospital (4.3%) responded that there needs to be communication among IRB, investigator, and sponsor. Conclusion: After conducting a nationwide survey on how IRB in university hospital determines risk during review of clinical trials, it is reasonable to use 4-level risk classification (less than minimal, low, moderate, high risk); the most utilized method among hospitals. Moreover, personal information and conflict of interest associated with clinical trials have to be considered when reviewing clinical trial protocols.

이선주,남기대 ( Sun Ju Lee,Ki Dae Nam ) 한국공업화학회 1993 공업화학 Vol.4 No.1
N/A Recently we are interested in the biosurfactant. Biosurfactant have a low toxcity and easily biodegradable compound. Pseudomonas sp. 13 was isolated from soil. This microorganism produced biosurfactant that consists of glycolipid R-1 and R-2. A time course study of fermentation indicated that the appearance of glycolipid in the fermentation broth the commencement of the stationary phase with the respect to biomass. The effect of variation of the media components such as amount of glucose, nitrogen, phosphate and metal ions has been investigated The following values found to be optimum for biosurfactant production (glucose, 20 g/ℓ; carbon to nitrogen ratio, 40; carbon to phosphate, 18; FeSO₄·7H₂O 20 ㎎/ℓ).

심장의 활성 근육의 움직임에 의하여 발생되는 전기적 변화량을 나타내는 심전도는 부정맥 또는 허혈성 심장 질환을 진단하는데 널리 활용되고 있다. 특히 심실빈맥(Ventricular Tachycardia) 또는 심실세동 (Ventricular Fibrillation)과 같이 치명적인 심장리듬이 발생하기 이전에, 심실조기수축(Ventricular Premature Contraction)을 검출하여 생명을 위협할 수 있는 부정맥을 조기에 진단할 수 있는 연구들이 일부 진행되고 있다. 이에 따라서 본 연구에서는 심전도 신호의 R-R 간격 정보와 R-peak 정보의 진위성을 판단하여 PVC 부정맥 패턴뿐만 아니라 PVC 파형이 연속적으로 진행되는 PVC-RUNs을 효율적으로 검출할 수 있는 부정맥 진단 알고리즘을 제안하고자 하였다.
