Fischer-Tropsch synthesis (FTS) was carried out in heat-exchanger typed reactor with cobalt metallic foam catalyst. Considering the heat and mass transfer limitations in the cobalt catalyst, a Co-foam catalyst with an inner metallic foam frame and an outer cobalt catalyst was developed. The Co-foam catalyst was highly selective toward liquid hydrocarbon production and the liquid hydrocarbon productivity at 203?C reached to 52.5ml/(kg_{cat}{cdot}h), which was higher than that obtained by the Co-pellet. Furthermore, the heat-exchanger typed reactor was developed to efficiently control the highly exothermic reaction heat. The reaction heat generated in the FTS reaction on the cobalt active site was easily transferred to reactor wall by the metallic foam in the catalyst and the transferred reaction heat was directly removed by the hot oil which circulated the wall side of the heat-exchanger typed reactor.

大韓帝國期 ‘傳’類 歷史書와 그 歷史觀

梁正鉉(Yang Jung-hyun) 역사교육연구회 1999 역사교육 Vol.72 No.-

This paper intends to analyze biographies published in the Great Han Empire from the historical perspective. Biography is a type of historiography. It provides numerous sources for the value systems and historical consciousness at that time. This study focused on analyzing biographies and Its Historcal Perspective in the Great Han Empire, with relation to contemporary political spheres. ‘Gijunche(紀傳體)’ was considered as typical Oriental historiography. Biographical writing comprises an important part in ‘Gijunche’. Biography in East Asia was used to tell right from the wrongs. In Korea, it was around ‘Eulsaneukyak(乙巳勒約, 1905)’ that biographical writing got wide-spread. Persons who contributed to the saving or reinforcing of the country were chosen as the main characters of biographies. There were four distinct categories in the biographies. The first category aimed to overcome the crisis of the Great Han Empire by preserving the national essence. The second laid the primary focus on fortifying the country by learning from the foreign civilization. Foreign heroes who expanded their territories or increased the national wealth were the leading characters from this stance. Third, lessons were pursued from the heroes who saved their country which was in similar situation with the Great Han Empire. Three Founding Fathers of Italy were discussed in this context. Fourth and finally, great explorers appeared as the main character of the biography. Young adults were encouraged to raise progressive attitude toward the future through the reading of explorers’ biography. All these four categories were based on the heroism, which regards the hero as the chief power of history. Now, there are some people who believe in the power of ordinary men in history. ‘Figures’ is an essential factor in teaching and learning history. Biographical history instruction constitutes a significant part in contemporary history education. Biographies in the Great Han Empire needs reconsidering from the educational point of view.

조선 초기 원경왕후 喪葬禮 의식과 그 특징

양정현(Yang, Jung-hyun) 한국역사민속학회 2014 역사민속학 Vol.0 No.45

본 연구는 조선 초기 凶禮의 정비 과정이라는 연속선상에서 원경왕후 국상을 하나의 기점으로 파악하고 그 특징을 喪制의 변화 및 의식 절차의 분석을 통해 제시하는데 목적이 있다. 세종 2년 발생한 태종 妃 원경왕후의 국상은 조선에서 국왕이 喪主가 되어 진행하는 三年喪의 의식 절차가 정비되어, 그 의주가 실록에 기재된 최초의 사례였다. 국상 복제 논의에서는 기존에 행해오던 역월제를 탈피하여 졸곡의 의미가 강조되었다. 기존의 도감 운영 체계를 정리하여 빈전·국장·산릉 3도감만을 운영하게 되었으며, 불교 관련 의례는 대폭 축소·규제되게 되었다. 삼년상기간 동안 국왕의 친행을 고려한 의식 절차도 새롭게 정비되었다. 의식의 기본 패턴은 拜禮·哭-行禮-拜禮·哭로 이루어졌는데 虞祭를 기점으로 奠과 祭로 구분되었다. 이는 태종대 길례 의식의 정비가 이루어진 바탕에서 古制에 기반한 ‘奠’과 祭’의 이해가 반영된 결과였다. 그리고 이러한 패턴을 기준으로 개별 의식 절차의 분석을 행하였다. 이를 통해 원경왕후 국상에서 국왕이 친행하는 실질적인 삼년상 실행을 위한 상장 제도 및 의식 절차의 제정과, 그 바탕이 된 고제의 이해·수용 수준을 확인할 수 있었다. This study focuses on the funeral rites for Queen Wongyeong during the early Joseon period as part of a review of the changes in the state funeral system and ceremonial procedures. Conducted by the king in his role as chief mourner, the state funeral for King Taejong’s wife Queen Wongyeong that emerged during the 2nd year of King Sejong marked the first example recorded in the sillok (Annals of the Joseon Dynasty) of the three year-mourning rite being applied. In terms of the clothing for the state funeral, the significance of Jolgok (a rite conducted on the 100th day following the day of death) was emphasized, while the existing yeokwolje (period of wearing mourning clothes, one month was equated with one day) was abandoned. The existing temporary office system for state funerals was reorganized into a three-office system consisting of the Binjeon dogam (Office for Chapel of Rest), Gukjang dogam (Office for Funeral Rites), and Salleung dogam (Office for the Establishment of Royal Tombs). Buddhism-related rites greatly decreased and were increasingly regulated. The ceremonial procedures were also modified in accordance with the rites directly conducted by the king during the three-year mourning period. The basic pattern of the ceremonial procedure consisted of kneeling / wailing - salute - kneeling/ wailing, and, based on the wuje (rites to console the deceased), was divided into ‘make offerings to the deceased’ (奠, jeon) and ‘hold a memorial service for the deceased’ (祭, je). This reflected the differing perceptions of jeon (奠) and je (祭) following the establishment of auspicious rites (gillye) during the reign of King Taejong. In short, the state funeral for Queen Wongyeong provides materials with which to analyze the establishment of the funeral rites and ceremonial procedures designed based on the actual three-year mourning period observed by the king, study the ritual ceremonies conducted during the ancient period, as well as foster an understanding of ancient systems.

2007, 2011 역사과 교육과정 개정 논리와 계열성

梁正鉉(Yang Joung-Hyun) 역사교육연구회 2011 역사교육 Vol.120 No.-

National History Curriculum revisioned twice In 2007 and 2011. In each Curriculum, Korean history and world history were integrated to one subject. Elementary school fifth grade social studies is composed entirely of Korean history. Secondary school history is composed of Korean history and world history. 2007, 2011 national history curriculum based on history teaching intensification policy in the year of 2005, 2011. The logics of National history curriculum revisions are two. First, A counter-move to distorted historical accounts about Korea by neighbor nations. Need to comprehension about foreign nations in globalization. 2007 national history curriculum acquired coherence of scope. But failed in sequence. 2011 national history curriculum don’t offer objectives of the elementary, secondary and highschool history. And standard achievements also don’t obtain coherence of sequence. It is necessary give attention to some points for achieve coherence of sequence. History curriculum must be made as a result of enough discussion between elementary school and secondary school. And history curriculum should offer guidelines for organization of contents.

The crisis of world history education came not only from shortened and smallized in curriculum but also from incoherence of its contents. To overcome this crisis, we have to propose alternative organization of world history courses.<br/> First, we must reconsider the Euro-centric perspectives and Orientalism. And we must point out that both Western Europe and China overwhelmed world history. For instance, if we want to transcend Euro-centralism and Orientalism, we must give balanced treatments to Oriental civilization and Greek-Roman world by adding more histories of Asia Minor and Near Eastern Asia including the histories of Persia, Parthia and Egypt, which have not been given enough treatment.<br/> We may suggest central themes to organize the world history textbook because the selection and exclusion are inevitable. For instance, A Green History of the World has a subtitle of 'the environment and the collapse of great civilization'. In this article, besides 'developments' 'multi-cultures' 'cross-connections' etc. I would also propose other several principles in organizing secondary world history textbook: 1) overcoming Euro-centric perspectives and Orientalism 2) integrating the social studies' contents into the world history's 3) organizing world history in terms of the scope, 'change and development of region' in sequence.

「무진기행」에서 <안개>로의 매체전이 양상 연구 -인식론적 책무 개념을 중심으로-

양정현 ( Yang Jeong-hyeon ) 성균관대학교 인문학연구원(성균관대학교 인문과학연구소) 2017 人文科學 Vol.0 No.67

이 글은 김승옥의 단편소설 「무진기행」(1964)과, 이 소설을 영화화한 김수용의 <안개>(1967) 사이의 매체전이적 양상을 인식론적 책무 (epistemological commitment)의 관점에서 조망해 보는 것을 목적으로 한다. 인식론적 책무란, 언어나 그림, 음악과 같은 어떤 양식(mode)이 특정한 상황이나 지식, 특성을 재현하고자 할 때 반드시 특정한 의미론적 사항이 뒤따르기에 발생하는 것이다. <안개>는 매체전이 과정에서 원작의 의미론적, 주제적 동일성을 최대한 담보하려는 작품이며, 그렇기에 언어와 영상이나 음악이라는 표현 양식에 따른 정보의 차이를 비교하기에 적합한 작품이라고 할 수 있다. <안개>에는 테크놀로지로서의 매체가 가지는 한계로 인해 발생한 현상과, 도리어 그로부터 의미론적 풍부함이 증대되는 사례가 존재한다. <안개>에서는 「무진기행」에서 다소 절제되었던 윤희중에 대한 아내의 심리적 구속과 그로부터 발생하는 내적 갈등이 보다 강조되고 있다. 영화에서 아내와 기준의 대화씬은, 인식론적 책무의 측면에서 볼 때, ‘특정한 행동을 하면서 특정한 말을 한다’라는 기본적인 상황에서 반드시 제시되어야 하는 ‘특정한 행동’을 시각적으로 적절히 변경함으로써 의미를 더욱 효과적으로 전달해준다. 또한 <안개>에는 감각적 채널로서의 매체에 따른 각각의 양식이 갖는 상이한 인식론적 책무와, 그로 인해 발생한 의미론적 변화 사례가 존재한다. 인물 성격묘사나 의미론적 계열화의 측면에서 볼 때에는 언어와 이미지의 차이로 인해 조의 성격묘사의 의미론적 응집성이 약화되며, 언어적 유사성에 의존하는 미친 여자, 자살한 술집 작부, 하인숙 사이의 의미론적 계열화는 거의 존재하지 않는다. 이로 인해 ‘부끄러움’에 중점을 둔 소설의 결말과 영화의 결말은 다소 차이를 보일 수밖에 없다. This essay aims to examine the transmedial aspects between the Kim Seung-ok’s short story “A Journey to Mujin” (Mujingihaeng, 1964) and Kim Soo-yong’s film Mist (An-gae, 1967) from the standpoint of epistemological commitment. Epistemological commitment occurs when certain modes, such as language, image, and music, must entail certain semantic points when trying to reproduce a particular situation, knowledge, or trait. Mist is a film that attempts to maximize the semantic and subject identity of the original work in the process of media transition, and therefore, it is suitable to compare the difference of information according to the specific modes like language, image, and music. From the above standpoint, there is a phenomenon caused by the limitation of the medium as a technology in Mist, and a case where the semantic prosperity is increased in spite of that limitation. One of the characteristics of Mist is that the wife’s psychological restraint on Yoon Hee-jung and the inner conflict, which was somewhat moderated in “A Journey to Mujin,” are more emphasized than fiction. The dialogue scene of the pre-departure to Mujin is appropriately modified to convey the meaning more effectively by changing the visual image of ‘specific action’, which is a compulsory element under the basic situations of ‘making specific utterances and taking action simultaneously.’ In addition, there exist different aspects of epistemological commitment in each mode with regard to the media as sensory channels, and the case of semantic changes that have arisen therefrom. In terms of the characterization and a chain of semantic similarity, the description of Jo’s character is weak because the differences in language and image, semantic integration among a mad woman, a self-slaughtered hostess and Ha In-sook, who all depend on linguistic similarity, are hardly found. As a result, the ending of the original fiction focusing on ‘shyness’ and the film counterpart show more or less a difference. The question of how we express something is directly related to the question of how it can be interpreted, as we cannot insist on the idea that there is a completely media-independent content. Epistemological commitment is a particularly useful concept for extensively analyzing this problem because it is derived from an inevitably intertwined condition in terms of content and form. The value of this concept as a general criterion can be more accurately judged when a quantitative analysis of transmedial aspects would be accumulated.

「청소년 방과 후 아카데미」프로그램에 대한 저소득층 청소년의 만족도 조사

양정현(Jung Hyun Yang) 한국청소년문화연구소 2011 청소년 문화포럼 Vol.- No.27

The purpose of this study lies in surveying the satisfaction of the teenagers in low income families with after-school academy, and setting its results as the basic data for development and operation of after-school academy program for teenagers program to supply the students with a valuable program. To accomplish such a goal, 220 teenagers attending after school academy in Daegu area were chosen for questionnaire. 215 out of 220 questionnaires were collected, 15 unsuitable copies among them were excluded again, and total 200 questionnaires were processed statistically. Then the satisfaction with the after-school academy program for teenagers(lesson, activity, leaders, lecturers facilities, meal service, and guidance for homecoming) and the differences in satisfaction according to the general traits of learners(sex, grade, joining duration, and learning level), and satisfaction with their own change were analyzed. Following are the study results. First, the learners were satisfied highly with lesson, activity and leaders, lecturers relevant to the after-school academy for the teenagers while their satisfaction with other areas was on the average. To raise learners` satisfaction, quantitative extension and highly qualified service should be offered, and programs connected from each other need to be developed. Second, in the differences in satisfaction of the students with the program according to learners` general traits(sex, grade, joining duration, and learning level), those students that showed high satisfaction were female students in sex, 4th grade in grade, within 6 months in joining duration, and less than 40 points in learning level. As those students participating in after-school academy for teenagers belong to very various groups in their sex, grade, and their position, they need to receive the direction and support matching their traits. Third, the leaners gave positive responses in general to the question if they have changed after they participated in after-school academy for teenagers, and showed high satisfaction with the facts that they made many different friends, and enjoyed cultural life through experience activities. As the students from the poor families don`t usually get proper upbringing, the after-school academy for teenagers need to focus on character education their parents are not able to give to help the teenagers with their holistic development and to change their life into positive ways. Based on the results above, the after-school academy for teenagers needs to make efforts constantly to detect what the learners want and develop new programs and operation methods.
