There are growing concerns about designing classroom or school environments influencing teaching and learning activities. However, there are little research on how students perceive the physical characteristic of the classroom and whether physical factors of classroom affects students' learning. The purpose of this study aims to reveal the different perception of college students on their classroom environments depending on where they take class, traditional classroom or newly constructed classroom. Also, the study demonstrates how the difference of classroom environment affects students' learning outcome. The results of this study suggests that classroom should be designed considering the perceptions of the students and their teaching and learning activities.

During the Joseon dynasty, the Gwansanggam (觀象監, The Royal Astronomical Observatory) was the royal administration in charge of Astronomy (天文), Geography (地理), Calendars (曆), Astronomical and meteorological observation (測候), and Timekeeping (刻漏). Of those affairs, the Astronomical Almanac compilation was most important. In this paper, we study the education and selection of astronomical officials in the 19th century during the Joseon dynasty, focusing on Astronomical Almanac officials. According to this study, their main area was calendar calculation, and they were involved in Astronomical Almanac compilation for nearly 40 years, until they resigned. In addition, they served as Samryeok-susulgwan (三曆修述官, Official for calendar calculation by the $Sh{\acute{i}}xi{\grave{a}}n$ calendar), and Ilgwa-gamingwan (日課監印官, Official printing supervisor). To undertake these core duties, an official had to pass several examinations and courses. The Gwansanggam (after Gwansangso) carried out the educational function for the officials. In particular, reserved officials of the astronomy division had to be educated starting with a trainee course.

The royal astronomical observatory compiled the Astronomical Almanac during the Joseon dynasty, though there were some changes of its organization. However, the observatory underwent sudden changes in the late period mainly due to the influence of historical events such as the Gabo (甲午) and The Eulmi (乙未) Reforms in 1894 and 1895, respectively, and the Japanese invasion in 1910. In this paper, we study the changes of the compilation institution of the Korean Astronomical Almanac and of its organization for the period of 1894 to 1912. During this period, the name of the observatory had been changed several times, from Gwansanggam (觀象監) to Gwansangguk (觀象局) in 1894 and to Gwansangso (觀象所) in 1895. In addition, the affair of the Astronomical Almanac compilation was transferred to the Editorial Bureau [編輯局] of the Ministry of Education [學部] and to the Editing Department [編輯課] of the Governor-General of Korea [朝鮮總督府]. In 1907, the Gwansangso was abolished. Moreover, the affair of timekeeping was separated and the official number of personnel was reduced to less than 5% compared to that of Gwansanggam. Consequently, the royal astronomical observatory was significantly reduced in terms of its functions and the organization through the process of those changes. Therefore, we believe that this period is important when seeking to understand the transition between the traditional Astronomical Almanac of the Joseon dynasty and its modern astronomical counterpart of the present day.

Purpose: The purpose of this study was to evaluate changes in the lower extremity kinematics of subjects with dynamic knee valgus after we applied non-elastic tape while they performed overhead squat. Methods: Twenty-five subjects (12 females, 13 males) with dynamic knee valgus participated in this study. Hip and knee joint kinematics and medial knee displacement were measured during overhead squat with and without hip correction taping. Results: Hip joint internal rotation, knee valgus, and medial knee displacement were significantly lower during overhead squat with hip correction taping than without hip correction taping, but there was no significant difference in hip joint flexion and abduction. Conclusion: Hip joint correction using non-elastic taping is recommended to subjects with dynamic knee valgus to improve their lower extremity movement and alignment during overhead squat.

This study is about the meaning of wooden brackets that are distinctive elements of wooden architecture in Korea, Japan, and China. Existing studies about wooden brackets have been limited to the boundary of formalism, so the object of this study is to make a breakthrough in the field of those studies. The Wooden brackets in this study are considered to be decorative elements, and the principles of their design are examined. The specific subject of the study is wooden architecture with Jusimpo-styled brackets that have brackets only on pillars. The definition of Jusimpo is reexamined first, and ChulMok-Ikkong which has not been regarded as a Jusimpo-styled wooden bracket is interpreted as Jusimpo-styled one in this study. Categorized into three types, Jusimpo is examined how it is expressed according to the type of the roof in a building. In view of the results, the wooden bracket system is an effective technique to express the formality, and two designing principles can be seen in Jusimpo; one that wooden brackets observed externally are standardized and regarded as the same ones, and the other that the style of wooden brackets used in the most formal building is Yi-ChulMok. These designing principles mean that the carpenter who was in charge of building the architecture had certain principles when expressing wooden brackets as well as the roofs according to the class of the architecture. In addition, although the styles of wooden brackets that were used in the most formal architecture during the Chosun period were mostly Dapo, Jusimpo in the form of Yi-ChulMok was also adopted in some temples depending on their scale, and that means Jusimpo-styled wooden brackets were never considered to be inferior to Dapo-styled ones. And this point leaves the argument that the reexamination of Jusimpo-styled wooden brackets which have been regarded as the style used in the attached building or small structures since the Choun dynasty should be conducted.

본 연구는 한국 특산식물 진범종자 휴면유형 및 배발달 조건을 밝히고자 수행하였다. 무처리 종자의 경우 15/6℃, 20/10℃, 25/15℃에서 14.0±2.83, 14.0±2.83, 2.7±4.81%의 낮은 발아율을 나타냈다. 5℃에서 4주간 습윤처리한 결과, 73.3±6.11, 61.3±6.11, 50.7±16.2로 발아율이 향상되었으며 8주 처리시 15/6℃에서 80.0±4.00의 높은 발아율을 나타내었다. 8주간 2주 간격으로 종자에 대한 배의 비율을 관찰한 결과, 5℃ 습윤처리시 0.26에서 0.65으로 증가한데 반해, 25/15℃에서는 0.45로 저조한 생장을 보여 저온습윤처리가 진범종자의 배생장에 효과적인 것을 확인하였다. 5℃, 25/15℃조건 500, 1,000ppm 지베렐린(GA3)을 처리한 결과 모든 처리구에서 14% 미만의 발아율을 나타내 지베렐린 처리는 진범종자의 휴면타파에 효과적이지 않은 것으로 판단되었다. 따라서 진범종자의 휴면유형은 형태 생리적 휴면이며, 휴면타파에는 저온습윤 처리가 필요한 것으로 판단된다. This study was conducted to serve information for the research of embryo growth requirements and a type of seeds dormancy of A. pseudolaeve Nakai, a Korean endemic species. The germination percentage of untreated seeds in control plot was 14.0±2.83, 14.0±2.83, 2.7±4.81% at 15/6℃, 20/10℃, and 25/15℃. After four weeks of cold stratification, final germination percentage of seeds was improved to 73.3±6.11, 61.3±6.11 and 50.7±16.2 at 15/6, 20/10, and 25/15℃. After eight weeks germination rate was the highest 80.0±4.00 at 15/6℃. Embryo growth was monitored for eight weeks in every two weeks intervals in the seeds incubated at 5℃, 25/15℃. Embryo ratio(embryo/seed) increased from 0.26 to 0.65 at 5℃ where as 25/15℃ incubated seeds was less embryo growth percentage. Therefore, Cold stratification was effective in embryo growth of A. pseudolaeve. On the other hand, seed incubating at 5℃, 25/15℃ after treating in Giberellic acid(GA3-500, 1,000ppm), germination percentage improved better 500ppm than control. However, only 13.3±1.33% of treated seeds were germinated. This indicates that Gibberellic acid(GA3) was less effective in breaking dormancy of seed in A. pseudolaeve. Therefore, seeds of A. pseudolaeve required cold stratification for dormancy break and possess deep complex morpho-physiological dormancy.

산림청 지정 희귀식물(위기종) 여우꼬리풀은 자생지가 매우 제한되어 있고 개체수도 부족하여 종자 발아촉진을 이용한 현지외 보전전략 수립을 위해 본 연구를 수행하였다. 종자의 발아촉진 전처리는 GA3(0, 500, 1,000ppm)처리 및 저온습윤(0, 8, 16주)를 수행하였다. 발아 온도대는 세 가지 변온(15/6℃, 20/10℃, 30/20℃)으로 구성하였으며, 14시간 광조건으로 발아 종료시까지 매일 발아종자를 기록하였다. GA3 처리결과 30/20℃에서 1,000ppm처리 종자의 경우 무처리 0%에서 78±2.83%로 발아율이 증가하였다. 또한, 15/6℃에서는 500, 1,000ppm처리시 무처리에 비해 20% 이상 발아율이 증가하였다. 저온처리 대조구의 경우 15/6, 20/10 30/20℃ 각 온도대에서 6.0±2.83, 45.3±2.31, 0%의 낮은 발아율 보인 반면, 저온 처리시 발아율이 확연히 증가하였다. 8주간 저온 처리한 종자의 경우, 5/6℃, 20/10℃, 30/20℃각 온도에서 85.3±6.11, 96.0±0.0, 86.0±2.83%의 발아율을 나타내었으며, 16주간 저온처리한 종자의 경우 15/6℃, 20/10℃에서 97% 이상의 높은 발아율은 나타내었다. 평균 50% 이상의 발아율을 나타내는데 걸리는 시간(G50)은 21일 이내인 것으로 확인되었다. 그러므로, 여우꼬리풀의 발아에는 2주 이상의 저온 습윤처리가 요구되며 발아온도대의 범위는 광범위한 것으로 판단된다. Aletris glabra Bureau & Franch. is designated as an endangered species by the Korea Forest Service. With a view to improving ex situ species conservation, we researched how to promote germination of A. glabra seeds. We analyzed the germination responses to GA3 concentration(0, 500 and 1,000ppm) and cold stratification period(0, 2, and 4 months). The temperature requirements for germination were determined by incubating seeds in light(14h daily photoperiod) at 12/12 daily alternating temperature regimes(15/6, 20/10 and 30/20℃)and germination seeds recoded at one-day intervals. Germination of seeds which were treated with 1,000ppm GA3 was increased from 0% to 65.3±18.9% at 30/20℃. We also observed that the germination of seeds treated with 500 and 1,000ppm GA3 was increased by more than 20% at 15/6℃. The non-stratified seeds germinated 6.0±2.83, 45.3±2.31, and 0% at 15/6, 20/10 and 30/20℃ respectively. However, cold stratification significantly increases the germination of A. glabra seeds. Eight-weeks stratified seeds were germinated 85.3±6.11, 96.0±0.0, and 86.0±2.83% at 15/6, 20/10 and and 30/20℃, respectively. After 16 weeks of cold stratification, seeds were germinated over 97% at 15/6 and 20/10℃. In average for 50% germination(G50) of all stratified seeds it takes approximately 21 days under three fluctuating temperatures. With this result, cold stratification(over eight weeks) promoted germination of A. glabra seeds with widening the temperature range for germination.

이 연구는 초등학교 교사가 수업분위기 중심으로 자기수업컨설팅을 실시하는 과정의 경험과 이러한 자기수업컨설팅 경험이 교사에게 주는 의미를 탐색하는 데 목적이 있다. 연구는 G시 G초등학교 2학년 1개 학급의 국어과 수업을 대상으로 진행되었다. 먼저 연구자는 자신의 수업 속 문제점 및 고민을 파악하였다. 이를 바탕으로 교실의 수업분위기를 살펴보기로 하였다. 2회의 수업을 촬영하고, 수업동영상을 보며 수업분위기 분석 도구를 활용하여 학급의 수업분위를 분석하였다. 분석 내용을 바탕으로 개선방안을 생각하여 이를 3, 4차 수업에 적용하였다. 3, 4차 수업 또한 같은 방식으로 분석하고 개선 방안을 5차 수업에 적용하였다. 이 과정에서 교사의 성찰 일지와 학생 설문을 활용하여 더욱 심층적인 분석이 이루어질 수 있도록 하였다. 연구 결과, 자기 수업컨설팅 단계별로 다음과 같은 경험을 하였다. 되돌아보기 단계에서 교사는 자신의 수업분위기 상황을 직면하고 무엇이 개선되어야 하는지 방향을 탐색할 수 있었다. 들여다보기 단계에서는 교사가 수업분위기 관련 수업행동을 객관적으로 파악하고 개선 위한 구체적 방안들을 계획할 수 있었다. 그리고 새로운 경험하기 단계를 통해 개선안을 적용하며 수업분위기를 실제로 개선해나갈 수 있었다. 이러한 자기수업컨설팅 과정을 통해 실제적인 수업분위기 개선을 이끌어냄으로써 교사의 수업전문성 향상에 도움이 되었고 또한 객관적으로 자신의 수업 행동을 파악하고 그 변화를 관찰함으로 교사의 수업에 대한 자기효능감 또한 높아지게 되었다. The purpose of this study is to examine the experiences of elementary school teachers in the process of self-study consulting using the class-atmosphere analysis tool and the meaning of self-study consulting experience to teachers. The study was conducted in a Korean language class in one class of 2nd grade in G elementary school. First, the researcher identified problems and concerns in her class. Based on this, the school decided to examine the classroom atmosphere. The class division was analyzed using tools for analyzing class crisis while filming two classes and watching a video clip. Based on the analysis results, improvement measures were considered and applied to the third and fourth classes. The third and fourth classes were also analyzed in the same way and improvements were applied to the fifth class. Further analysis was made using the teacher s reflection log and the student questionnaire. As a result of the study, the following experiences were experienced for each phase of self-class consulting. During the review phase, the teacher was able to face his class-crisis situation and navigate in the direction of what needs to be improved. In the step of looking into the classroom crisis, teachers were able to objectively identify classroom behavior and plan specific measures to improve it. And through the new experience phase, we were able to actually improve the class atmosphere by applying improvements. Through this process of self-class consulting, it helped improve the teacher s teaching expertise by leading to the improvement of the actual class divide, and by objectively understanding his or her classroom behavior and observing the changes, the teacher s self-efficacy in his or her classes was also enhanced.
