朴星完,林泳範,鄭州桓,成洛煥,金喆煥,申明徹 成均館大學校 科學技術硏究所 1994 論文集 Vol.45 No.2

This paper is intended as an investigation of fault location for underground line. Over the past few decades a considerable number of studies have been made on protection of underground line. However, these approaches require the interruption of electric power supply from source for fault location estimation. Therefore, we proposed fault location algorithm for underground line protection without interruption of electric power supply. Cross correlation function is used in this algorithm. Also, EMTP data is used to demonstrate the capability of the proposed fault location algorithm.

Ki-Wan Oh(Ki-Wan Oh),Hwa-Kyung Lim(Hwa-Kyung Lim),Cheol-Beum Park(Cheol-Beum Park),Im-Chul Shin(Im-Chul Shin),Jin-Tae Hong(Jin-Tae Hong) 고려인삼학회 2002 Journal of Ginseng Research Vol.26 No.4

Crude synaptic membrane fractions from the frontal cortex, striatum, brain stem and whole brain of rat were prepared to assay the effects of ginseng total saponin (GTS) on [³H]DAGO bindings of the opioid μ-receptors. Scatchard plots analysis binding data demonstrated that GTS (0.1 mg/ml) decreased the affinity of specific [³H]DAGO bindings without changes in Bmax in the frontal cortex and striatum. On the other hand, GTS did not affect the [³H]DAGO bindings in the brain stem and whole brain. These results suggest that the regulation of [³H]DAGO bindings by GTS may play roles in the change of the pharmacological responses of μ-opioids.

Sang Wan Lim,Kyo Chul Seo 국제물리치료학회 2011 Journal of International Academy of Physical Ther Vol.2 No.2

The purpose of this study was an determine whether elastic band on treadmill training might effect the chest expansion and pulmonary function of the 20's men. 40 subjects with experimental group(male: 20) and control group(male: 20) was participated in experiment. During four weeks, each group participated thirty minutes for three times per week. Subjects were assessed using pre-value and postvalue measurement chest length(chest length for resting, chest expansion) and pulmonary function(forced vital capacity, forced expiratory volume at one second, FEV1/FVC, peak expiratory flow, vital capacity, tidal volume, expiratory reserve volume, inspiratory reserve volume) by the CardioTouch 3000S(BIONET, USA). These findings suggest that experimental group can be used to improve chest expansion, pulmonary function than control group. In comparison of both groups, post-test was more improved in experimental group. In conclusion, experimental group helped improving function of pulmonary volume and respiratory muscle, and thus it indicates that the functions will be more improved through the continued respiratory exercise program.

This study is to examine the effects of a feedback breathing device exercise and diaphragm breathing exercise on pulmonary functions of chronic strokes patients. The selection of 20 subjects was divided equally and placed into a experiment group and a control group and the intervention was applied four times per a week for five weeks. In each session, both groups received rehabilitative exercise treatment for 30 minutes, and a feedback breathing device exercise for 15 minutes. In addition, experimental group conducted a combination of diaphragm breathing exercise for 15 minutes. Prior to and after the experiment, patients’ pulmonary functions were measured using a spirometer. The pulmonary function tests included FVC, FEV1, FEV1/FVC, PEF, VC, TV, IC, ERV, IRV. With respect to changes in the pulmonary functions of both groups, the experimental group significantly differed in FVC, FEV1, TV, ERV but did not in PEF, FEV1/FVC, VC, IRV. The control group did not significantly differ in any of the tests. There were significant differences in FEV1, FEV1/FVC, TV, ERV between the two groups, but no significant differences in FVC, PEF, FEV1/FVC, VC, IRV between them after the experiment. The experimental group, which conducted a combination of a feedback breathing device exercise and diaphragm breathing exercise, saw their respiratory ability increase more significantly than the control group. The breathing exercise was found to improve pulmonary function in chronic stroke patients.

This study analyzed the pre-teachers` web-based instructional environment design experiences as opportunitines to advance their understanding of teaching, learning, and the role of the web-based learning environment. The pre-teachers` results of design and design experiences were analyzed as results. An e-learning system allowing learner initiated environment design was implemented with fourteen undergraduate learners in a pre-teacher course titled Introduction to Educational Technology during fall 2010, at a university in Seoul, Korea. Most participants in this undergraduate class plan to become K-12 teachers and brought their rich professional knowledge of teaching and learning to this course. The participants had the opportunity to become designers of a web-based teaching and learning environment in accordance with the course`s purpose. The participants were expected not only to learn current web-based technologies but also generate abstract knowledge about designing educational technology by working on design projects. The web-based teaching and learning environment design projects forced the participants to think deeply about evaluating the needs of the audience and to configure their design to meet these needs.In the design process, learners were engaged in activities that compelled them to practically study technology, education, and the interface between the two. For practical experience, learners in this class as pre-teachers completed projects that involved designing their own teaching and learning environments.

교실 내 공기 중 이산화탄소 농도가 학습에 미치는 효과에 대한 문헌 연구

임완철(Wan Chul Lim) 한국환경교육학회 2015 環境 敎育 Vol.28 No.2

교실 내 공기 중 이산화탄소 농도가 안전기준치 (1,000 ppm)를 넘는다는 연구가 국내외에서 발표되고 있음에도 불구하고, 이산화탄소 농도가 교수학습에 미치는 효과에 대한 연구는 발견하기 쉽지 않다. 본 연구는 실내공기중 이산화탄소 농도가 학습에 미치는 효과를 연구한 2005년 이후의 논문들을 탐색적으로 분석한 문헌 연구이다. 선택된 논문의 결과를 종합해보면, 환기를 하지 않는 교실은 4,000 ppm 이상 도달할 수 있으며, 이산화탄소 농도가 높은 환경에 짧은 시간 노출되더라도 학업수행능력에 영향을 받을 수 있으며, 교실 내 공기 중 이산화탄소 농도의 하루 동안의 변동 폭이 크고, 학업수행에 영향을 미치는 오염물질의 효과를 측정하는 도구가 부재하고, 이산화탄소 농도의 증가가 학업수행능력에 미치는 효과에 대한 체계적인 연구를 발견하기 어렵다는 사실이다. 탐색된 논문의 연구결과에 따라, 학업수행능력 증진을 위한 학교 실내환경 관리 체제 연구, 학습활동에 미치는 영향을 고려한 오염물질 지표 연구, 에너지 낭비가 적은 건물과 효과적인 교수학습의 조화를 위한 건물 설계 연구, 교사의 수업활동에 미치는 오염물질 효과 연구를 후속연구로 제안하였다. To assess the effect of the Carbon Dioxide (CO₂) concentration level in the classroom indoor air on the learning performance of students, a review study was conducted. for the purpose of this study, 42 studies were reviewed and 9 studies were selected. In a classroom with a low concentration of Carbon Dioxide, students paid attention and responded more quickly and accurately, but with a high concentration of Carbon Dioxide, students perceived the spatial abilities and language skills dropped descends and inappropriate decisions are increased, various programs, content, tools provided by teacher, were less intensive, or immersion. Overall, reviewed research assessed the effects of the Carbon Dioxide concentration level in the classroom indoor air on the learning performance of students is common and adversely influences the learning performance of students. Physical learning environment performance indicators and management systems development plan and subsequent research directions are suggested.
