광색에 따른 채도와 조도변화에 대한 고령자의 심리반응 연구
이희원,박지영,이진숙 한국색채학회 2020 한국색채학회 논문집 Vol.34 No.4
According to the Korean National Statics Office, South Korea will face the wave of elderly population increase. In this circumstance, changing mental and physical status, along with behavior characteristic, should be a lighting environment safe for them. For this goal, this research’s aim was to find out the elderly mental responses to lighted are for the elderly. We have analyzed and researched base on preliminary research to build this environment. Ten light colors were chosen for lighting, Red, Yellow Red, Yellow, Green Yellow, Green, Blue Green, Blue, Purple Blue, Purple, Red Purple, and they were all lit in low, middle and high saturation. Light intensities were measured in 40 lx and 80 lx. A comparative analysis was conducted on the emotional response to each light environment. Analysis results showed, it showed to get emotions like “comfortable/stable”, “happy/delighted”, “good”, “cheerful/active”, the environment should have low saturation lights. When in the middle to high saturation light, emotions effected thermal sense. When building a lighting environment for the elderly, the same light color will have different emotional results depending on saturation, so light color, brightness, and saturation have to be applied cautiously.
한국 대학생의 기초교양 교과목에 관한 수강 경향 분석 : 서울대학교 사례를 중심으로
이희원,서경호 한국교육컨설팅학회 2013 교육컨설팅연구 Vol.1 No.1
본 연구는 서울대학교 학부생들의 기초교양 교과목의 수강 경향을 분석하여 지난 수년간 기초교육 강화를 위한 노력이 학생들에게 어떻게 수용되고 어떤 교육적 성과를 거두었는가를 평가하고자 하였다. 분석 결과, 서울대학교 학부생들은 평균 8.49학기를 이수하였고, 대학에서 졸업요건으로 정해진 학점을 크게 벗어나지 않았지만 평균 전공 취득 학점은 2000년부터 점차 감소하는 경향을 보였다. 학과별로 전공 학점수를 더 많이 요구하는 경향을 보여서 대학이 전문 직업을 위한 고도의 지적, 직업적 훈련을 시켜야 한다는 목표와 근본적이고 기초적인 교육에 중점을 두어야 한다는 교육 목표 사이에는 적절한 균형이 필요한 것으로 판단된다. 또한 지난 5년 간 복수전공을 수강한 학생은 406명, 연합전공 31명으로 다양한 분야의 전공을 수강한 학생이 연평균 437명으로 나타났다. 이러한 추세는 학생의 사회적 관심 영역을 확장하고 교육적인 기초를 더욱 확고히 다지는 기회를 제공하였을 것이며, 다양한 학문적 경험을 통한 융합을 구현하는 것에 도움이 되었을 것으로 판단된다. This research analysed patterns in liberal arts course selections of SNU undergraduate students to evaluate the achievements of past efforts to improve liberal arts education. The overall results showed that out of the 8.49 semesters undergraduates took on average, the average of credits obtained from their majors had started to decrease from 2000, though they did not fail to meet the credits requirements for graduation. Faculties seemed to impose more stringent major credit requirements; a balance should be restored between the emphasis on core subject areas and the need for specialised knowledge for professional jobs and career paths. Statistics for the past five years revealed that an average of 437 students per year chose to major in more than two areas, with 406 students electing double majors and 31 choosing interdisciplinary majors. Such major selections would have been beneficial in that it helps establish a firm academic basis for students through various educational experiences, and encourages interdisciplinary thinking by broadening the students’ areas of interest. However, the pattern of students selecting liberal arts courses without considering possible connections or relevance to their coursework as a whole seems problematic, and effort must be made on an institutional level to uphold the overall objective of establishing liberal arts subjects. Certain faculties choose to establish their own liberal arts subjects instead of having students take the university-wide established liberal arts programmes. Such examples could provide effective solutions in that they allow for a diversity of interests (thus satisfying the aim of liberal art education) whilst ensuring that the courses interrelate. Results on the patterns of liberal arts course selection will help evaluate the accomplishments so far of the efforts taken to improve liberal arts education, and will hopefully aid in the implementation of further policies to improve higher education as a whole.
Asymmetric Absorption Profile of Damped Lyman Alpha and Beta Systems
이희원,Lee, Hee-Won 한국천문학회 2012 天文學會報 Vol.37 No.2
Due to the quantum interference of many atomic levels, the exact scattering cross section around a given resonance transition deviates from the Lorentz function when the frequency of the incident radiation is quite far from the resonance frequency. This atomic effect is quite significant in the case of damped Ly alpha systems, where HI column density is in excess of 10^20 cm^-2. In this poster, we present the deviation quantitatively taking into consideration of the Rayleigh and Raman scattering around Lyman alpha and Lyman beta.
