農用트렉터 牽引性能 比較試驗 硏究 : 二輪驅動型과 四輪驅動型 Two-wheel drive and Four-wheel drive

權純洪 건국대학교 1988 論文集 Vol.27 No.2

The tractive performance of a two - wheel drive tractor and four - wheel dirve tractor was measured to obtain data for economical uses and rational managements. The results obtained are summarized as follows ; 1. Maximum tractive force decreased in proportion to tractive speed increased, and that of the four - wheel drive tractor was higher than that of the two - wheel drive tractor. 2. Maximum drawbar power detected in travel speed of sixth gear and that of the four - wheel drive tractor was about 3.5∼7.1 % higher than that of the two - wheel drive tractor in accordance with travel speed. 3. In proportion to the tractive force increased, traction coefficiency, drawbar power and wheel slip radio increased. 4. Maximum fuel consumption ratio detected in travel speed of first gear at the lowest drawbar power and minimum fuel consumption ratio detected in travel speed of sixth gear at the highest drawbar power. Fuel consumption ratio of the four - wheel drive tractor was about 4% higher than that of the two - wheel drive tractor.

소크라틱 세미나 토론을 활용한 散文수업 방법 具案 -孟子 梁惠王 章句를 중심으로-

This paper is the introduction of Chinese and prose teaching methods using socratic seminar discussions. The Sokratic Seminar, which was embodied by taking ideas from Socrates' conversation method, is a model that improves students' communication skills and discussion skills. This method helps learners by stimulating thought processes that lead to a deep understanding rather than acquiring fragmentary facts about the text. This researcher devised a class by applying a socratic seminar discussion using the parts dealing with the ≪孟子≫ edition. The results are as follows. First, learner-led learning was achieved because even students who lacked achievement made questions and looked at the text repeatedly to participate in discussion activities using them. Second, students diagnosed their lives and society based on text through active discussion activities, and recognized that classical text was directly connected to problems in modern society and problems in their lives. Third, the socratic seminar discussion is a way to produce the best results, not to distinguish between superiority and inferiority, as in general discussion, so communication skills have improved by listening to each other's remarks and presenting alternatives when refuting. Chinese character classes using socratic seminar discussions can be a way to efficiently teach the content of the subject, and it is worth applying in the school field as it is one of the meaningful educational methods to develop learners' capabilities, and it is expected that follow-up models will continue actively in the future. 본 고는 소크라틱 세미나 토론을 활용한 한문과 산문 수업 방법의 具案이다. 소크라테스의 대화법에서 아이디어를 얻어서 구체화된 소크라틱 세미나는 학생들로 하여금 의사소통능력과 토론 기술을 향상시키는 모델이다. 이 방법은 텍스트에 대한 단편적인 사실들의 습득보다는 깊은 이해를 이끌어내는 사고 과정들을 자극시킴으로써 학습자들을 도와준다. 본 연구자는 孟子 <梁惠王 章句 上>편의 恒産과 恒心을 다룬 부분들을 활용하여 소크라틱 세미나 토론을 적용하여 수업을 구안하였다. 그 결과는 다음과 같다. 첫째, 성취가 부족한 학생이더라도 질문을 만들고, 이를 활용하여 토론 활동에 참여하기 위해 본문을 반복해서 보기 때문에 학습자주도 학습이 이루어졌다. 둘째, 학생들은 활발한 토론 활동을 통해 본문 텍스트를 기반으로 자신들의 삶과 사회를 진단하게 되고, 고전 텍스트가 현대사회의 문제, 자신의 삶의 문제와 직접적으로 연결되어 있다는 것을 인식하였다. 셋째, 소크라틱 세미나 토론은 일반적인 토론의 양상처럼 우열을 가리는 것이 아니라 최선의 결과를 도출해내면 되는 방식이기 때문에 서로의 발언을 경청하였고, 반박할 때에도 대안을 제시하는 등 의사소통 능력이 향상되었다. 소크라틱 세미나 토론을 활용한 한문과 수업은 교과 내용을 효율적으로 교수하는 하나의 방법이 될 수 있으며, 학습자들의 역량을 기를 수 있는 유의미한 교육 방법의 하나이므로 학교 현장에서 적용할 만한 가치가 있으며, 향후 활발하게 후속 모델 具案이 이어지길 기대한다.

동아시아 複都制와 多京制의 구분

권순홍 중국고중세사학회 2019 중국고중세사연구 Vol.54 No.-

This paper aims at proposing a distinction between dual royal cities system(複都制) and multiple capital system(多京制) that operated in East Asia. The core of this distinction key was to distinguish the meanings of royal city(都) and capital(京). Since Han dynasty, royal city(都) only referred to the cities where the royal shrine(宗廟) was built by emperor‘s power monopolizing the right to perform ancestral rites, and capital(京) referred to the top-level city within the administrative system under the bureaucracy. In general, royal city(都) was capital(京), but not all capital(京) were royal city(都). Specifically, Xin(新), Sui(隋), and Wuzhou(武周) operated dual royal cities by establishing royal shrine in Changan(長安) and Luoyang(洛陽) at the same time, while the Tang dynasty operated multiple capital system by organizing Changan, Luoyang and Taiyuan(太原) into the same top-level administrative unit, capital(京). On the other hand, in case of Ye(鄴) and Jinyang(Taiyuan) of Dongwei-Beiqi(東魏-北齊), and Heijokyo(平城京) and Naniwakyo(難波京) of 8th century Japan which were often interpreted as dual royal cities system(複都制), it can be understood as multiple capital, not dual royal cities, since Jinyang(Taiyuan) and Naniwakyo are of low status than Ye and Heijokyo. Dual royal cities system and multiple capital system also differed in their operating background. After the dynastic revolution, the operating backgrounds of dual royal cities system of Xin, Sui and Wuzhou focused on Luoyang as the same status of Changan in order to enhance the legitimacy of the dynasty. On the other hand, the operating backgrounds of multiple capital were different in each society. While Tang operated multiple capital system to secure a base for nationwide control, Dongwei-Beiqi operated multiple capital system in order to maximize the military function of Jinyang(Taiyuan) in the military confrontation with Xiwei-Beizhou(西魏-北周). 8th Century Japan's multiple capital system was a transitional royal city system established in the process of transition to the bureaucracy based on legal system(律令) after the acceptance of Tang's legal system.

Comparative Study on Efficiencies of Naturally-Ventilated Multi-Span Greenhouses in Korea

권순홍,정성원,권순구,박종민,최원식,김종순,Kwon, Soon-Hong,Jung, Sung-Won,Kwon, Soon-Gu,Park, Jong-Min,Choi, Won-Sik,Kim, Jong-Soon The Korean Society of Industry Convergence 2017 한국산업융합학회 논문집 Vol.20 No.1

This research analyzed the ventilation effect of the multi-span greenhouse based on the types of greenhouse structure, weather conditions, and locations inside the greenhouse. To compare and analyze the ventilation effects with different types of greenhouse, the uniform environmental conditions should be selected in advance. But these factors are not controlled and require tense many precision facilities and labor forces. Thus, the CFD simulation was used for the air stream to be analyzed qualitatively and quantitatively. In addition, for the ventilation effect analysis, the TGD (Tracer Gas Decay) was used to overcome the shortcomings of the current ventilation measurement method. The calculation error of ventilation rate using TGD was low (10.5%). Thus, the TGD is very effective in calculating the ventilation efficiency. The wind direction of 90 degrees showed the best ventilation effect. The ventilation rate also decreased along the air circulation path, and the rate was the lowest around the outlet. The computed fluid method (CFD) turned out to be a power tool for simulating flow behavior in greenhouse.

Diphenyliodonium염 존재하에서 비닐 에테르의 광양이온 리빙 중합(I)

권순홍,이연성,전현정,마석일,Kwon, Soonhong,Lee, Youngsung,Jeon, Hyunjeong,Mah, Soukil 한국섬유공학회 2002 한국섬유공학회지 Vol.39 No.4

Photo-induced living cationic polymerization of isobutyl vinyl ether (IBVE) has been newly developed in the presence of diphenyliodonium iodide (DPII). Zinc iodide was used as an activator in the polymerization reaction. A linear relationship between % monomer conversion and the number average molecular weight of the resulting polymer reveals the living nature. The increase in both the polymer yield and its molecular weight until the original monomer was exhausted reveals that the propagating cationic species have the long lifetime due to the absence of termination or chain transfer process. It became also evident that a PIBVE-based block copolymer can be obtained by the subsequent monomer addition technique from this photo-induced system. The effects of various factors such as concentrations of DPII and zinc iodide, temperature, and duration of photo-irradiation were also discussed.
