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.

최근 중국학계 고구려사 연구(2018~2021)의 몇 가지 변화

권순홍 동북아역사재단 2022 東北亞歷史論叢 Vol.- No.77

This article aim sat analyzing and evaluating recent research trends of Goguryeo history in China, especially from 2018 to 2021. Previous research has pointed out that research on Goguryeo history in China has greatly increased in quantity after the completion of the Northeast Project. However, there are still two limitations and problems. The first problem lies in the purpose of the research to interpret Goguryeo only as a local government or subordinate state of the dynasties in Zhongyuan(中原). The second problem is a research method that reflects only Chinese historical materials and research achievements except foreign historical materials such as Samguk Sagi and the research results of foreign academic circles. This article, however, evaluates recent research differently. Three characteristics are presented. First characteristic is that it actively presents problems in previous research and mentions identity of Goguryeo. Second, new research topics are explored by using various materials including foreign historical materials such as Samguk Sagi. Third, it presents new perspectives by actively introducing concepts and research results raised in foreign academic circles. It is worth noting that these recent changes are being led by young researchers in China, such as “高句麗渤海硏究青年學者工作坊(Workshop of young researchers studying Goguryeo and Balhae)”. The point to be wary of here is that their research has been deepening the theory of Zhongfan(宗藩) and Fanshu(藩屬) through diversification of viewpoints, and appropriation and redefinition of concepts. 이 글의 목적은 최근, 특히 2018년부터 2021년까지 중국의 고구려사 연구 동향을 분석·평가하는 것이다. 선행연구에서는 동북공정 종료 이후 중국의 고구려사 연구는 양적으로 크게 늘어났지만, 두 가지 한계와 문제점이 있다고 지적했다. 하나는 고구려를 중원왕조에 종속된 지방정권 내지 속국으로만 해석하려는 연구 목적의 문제이고, 다른 하나는 『삼국사기』 등의 외국 사료와 외국학계의 연구성과를 반영하지 않고 오로지 중국의 사료와 연구성과만 반영하는 연구 방법의 문제이다. 그러나 이 글에서 분석한 최근의 연구들은 달리 평가된다. 세 가지 특징이 확인되는데, 첫째, 선행연구에 대한 문제 제기가 활발하여 고구려의 주체성을 언급하기도 한다. 둘째, 『삼국사기』 등 외국 사료를 포함한 다양한 자료를 활용하여 새로운 연구 주제를 발굴한다. 셋째, 외국학계에서 제기된 개념과 연구성과를 적극적으로 도입하여 새로운 관점을 제기한다. 이러한 최근의 변화는 ‘고구려발해연구청년학자공작방(高句麗渤海研究青年學者工作坊)’ 등 중국 내 신진 연구자들의 주도로 이루어지고 있다는 점이 주목된다. 다만, 여전히 그들의 연구는 중국 중심적이며, 오히려 관점의 다변화와 개념의 전유/재정의를 통해 종번/번속 이론이 심화되고 있다는 점이 유의된다.

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

권순홍,이동재 한국한문교육학회 2023 한문교육논집 Vol.60 No.-

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.

고구려 도시 연구 試論

권순홍 수선사학회 2022 史林 Vol.- No.82

This article aims to define the concept of ancient city and confirm the actuality of the city of Goguryeo. Korean history study has used the term ‘도시(city)’ mixed with ‘도성(capital)’. Capital, however, is defined based on the ruling power, which is the appearance of the king and the landscape such as Jongmyo and the royal palace which symbolize the appearance. A city is defined by two conditions: concentration of population over a certain number of people and non-self-sufficiency/external dependence. Analysis of historical records and material data revealed that in the case of Goguryeo, an ancient state/capital was already established in the second century, but the non-self-sufficient city was formed around the middle of the third century. This means that the establishment of an ancient state/capital and the formation of a city are separate events. This article also captures the social division of labor, the separation of urban and rural areas based on it, and the market economy and non-self-sufficiency of urban with rural areas as production sites by analyzing historical records. It also confirmed the fact that the residents of the city had sense of superiority and treated the rural areas with disdain. .

The closed suction drain is commonly inserted after various surgical procedures. It has an important role to prevent possible hematoma or seroma that can cause postoperative wound problems. But there is still no consensus on managing the insertion site of suction drain after operation. Suturetie fixation of drain to skin and classical Y shape gauze dressing is a usually accepted method, but it has many limitations. We introduce a new approach to the care for the insertion site of suction drain by using occlusive transparent film dressing, IV3000(Smith&Nephew, London, UK). By using transparent film, insertion site of drain can be easily checked without removal of dressing. Because it can reduce the tension of suture-tie fixation, it helps to prevent skin injury. Furthermore, occlusive film dressing can block air leakage from insertion site of drain, and the water-proof character of film allows patients to take a shower without dressing change. This new method is more convenient, more efficient, and less harmful to skin than classic one.

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.

‘도성권’의 개념과 고구려 ‘도성권’의 등장

권순홍 고구려발해학회 2019 고구려발해연구 Vol.64 No.-

This paper suggests a new concept, 'sphere of royal city', for understanding the space of royal city. 'Sphere of royal city' addresses how royal city is living with its surrounding community and which kind of relationship is being established with this community. Therefore, this paper pays attention to the relationship between the life and space of residents of royal city. While existing concepts such as 'Wang-gi' and 'Gyeong-gi' are an administrative organization by the ruling power which explain royal city and its surrounding areas, 'sphere of royal city' is a sphere of life organized by the lives of residents. Specifically, it is composed of two parts: life zone of royal city which is not an administrative area, and satellite towns which was outside and in charge of production of royal city. As the level of self-sufficiency decreases and the external dependence increases, Goguryeo assigned the production of major food materials, such as grain and salt, as well as the production of stone and tile which are major building materials to the outside of the royal city. ‘Sphere of royal city' in Goguryeo which already existed in 4th century can be confirmed through this circumstance. 이 글은 도성 공간을 이해하기 위한 새로운 개념으로서, ‘도성권’을 제안한다. ‘도성권’은 자급자족하지 않는 사회로서 도성이 주변 지역 사회와 어떤 관계를 맺으면서 존립하고 있는지를 고민한다. 이로써 도성 주민들의 생활과 공간의 관계를 주목한다. 기왕에도 ‘왕기’ 혹은 ‘경기’와 같이, 도성과 주변 지역을 설명하는 개념이 있었지만 지배 권력에 의한 행정 편제였던 반면, ‘도성권’은 주민들의 삶에 의한 생활권이었다. 구체적으로 ‘도성권’은 행정 구역이 아닌 도성 생활권과 그 바깥에서 도성의 생산기능을 담당하는 위성 취락군으로 구성된다. 고구려 역시 도성의 비자급자족성과 외부의존성이 두드러짐에 따라, 주요 식자재인 곡물식량과 소금 등의 생산뿐만 아니라 주요 건축자재로서 석재와 기와 등의 생산을 도성 외부에 맡겼다. 이를 통해 우리는 4세기에 이미 존재했던 고구려의 ‘도성권’을 확인할 수 있다.
