척추손상환자에서 Succinylcholine 이 혈청 K+ 치에 미치는 영향
유경연,하인호,임채령 대한마취과학회 1990 Korean Journal of Anesthesiology Vol.23 No.3
Succinylcholine (Sch) has long been used to facilitate laryngoscopy and endotracheal intubation for general anesthesia, because of a rapid onset of intense but brief paralysis. However, exaggerated potassium (K^+) release following Sch, sufficient to cause ventricular dysrhythmias and cardiac arrest, has sporadically been reported in susceptible conditions, including spinal cord injury, severe burn, massive trauma and neuromuscular disorder. And diazepam has been shown to attenuate the increase in serum K^+ following Sch administration. The purpose of this study was to assess the effect of Sch on serum K^+ in patients with spinal cord lesions, and to assess the effect of pretreatment with diazepam (0.05 mg/kg IV) on potassium flux. The results were as follows: 1) Baseline K^+ values were not significantly different among the groups. 2) The time to peak increases in K^+ was 3 minutes following Sch in all groups. 3) The magnitude of maximum increases in K^+ following Sch were 0.32 Eq/l, 0.63 mEq/l, 0.06 mEq/I and 1,10 mEq/I in group 1, group 2A, group 2B, and group 3, respectively. 4) Diazepam pretreatment attenuated the increases in K^+ following Sch. From the above results, it can be concluded that Sch may safely be used to facilitate intubation in paraplegic patients, provided that they are normokalemic and pretreated with diazepam.

충남지역 S대학의 중앙도서관과 휴게시설의 총부유분진 및 총부유세균 농도 연구
이서빈,김지욱,임채령,이정민,정소진,이민혁,손부순 순천향대학교 기초과학연구소 2021 순천향자연과학연구 논문집 Vol.27 No.1.2
The average indoor concentration of the library's TSP was 0.03 ng/m³. TAB in library and lounge in college of engineering showed higher concentrations in corridors than indoors. The correlation coefficient between TAB and humidity is 0.985, so it is judged that there is a significant need for humidity control in indoor air quality management to reduce the concentration of total suspended bacteria(p<0.01).

수학교과와 정보교과를 융합하는 코딩수학 교육과정 및 교육방법 연구
강하람 ( Kang¸ Ha Ram ),임채령 ( Lim¸ Chae Lyeong ),조한혁 ( Cho¸ Han Hyuk ) 한국수학교육학회 2021 수학교육 Vol.60 No.4
본 연구는 초·중학교 수학교과와 정보교과를 융합하는 코딩수학 교육과정과 이를 위한 최소 코딩게임 기반 교육방법에 대한 연구이다. 지난 3년간 코딩수학 교육과정과 효과적인 교육방법을 초6학년과 중1학년 학생을 대상으로 연구하였다. 1차년도 연구결과, 공간좌표의 필요성에 따라 3차원 좌표의 수학적 개념을 포함하는 코딩환경으로 교육과정을 수정하였다. 2차년도 연구결과, 명령어의 위계성에 따라 건물 요소별 다른 수준의 명령어를 도입하여 자기주도적 학습이 가능하도록 개선하였다. 3차년도 연구 결과, 컴퓨팅 사고력 향상을 유도하는 최소 코딩게임 기반의 교수·학습 전략을 설계하고, 컴퓨팅 사고력 진단을 위한 평가 및 피드백을 개발하였다. 자기주도적 학습 및 컴퓨팅 사고력 증진을 유도하는 최소 코딩게임 기반 교육방법과 코딩수학 교육과정은 수학-정보교과의 융합교육 연구와 실천에 의미가 있다. This study is a study on the coding mathematics curriculum that converges elementary and middle school mathematics and information subjects and a minimum coding game-based education method for this. For the past 3 years, the coding mathematics curriculum and educational methods to effectively operate the curriculum were studied by applying them to 6th graders of elementary school and 1st graders of middle school. As a result of the first year of research, the coding mathematics curriculum was modified to a coding environment including the mathematical concept of a three-dimensional coordinate space, and the three-dimensional object was improved to be output as a real 3D print. As a result of the 2nd year study, it was improved so that even low-level students can build buildings by introducing different level commands for each component of the building so that self-directed learning is possible. As a result of the 3rd year study, a teaching-learning strategy based on a minimal coding game was designed to induce an increase in the level of computational thinking, and evaluation and feedback for diagnosing computational thinking were developed. Educational methods to promote self-directed learning and computing thinking ability, and researched coding mathematics curriculum are meaningful for the research and practice of the convergence education of school mathematics and informatics.
