        친환경농업 실천농가의 경영능력 진단

        이기웅,유찬주,박형달 한국유기농업학회 2006 韓國有機農業學會誌 Vol.14 No.3

        This study diagnosed the managerial ability of farmers in the Gokseong area and the Gwangyang area, and analysis was conducted especially placing focus on the difference in managerial ability on whether environmental friendly agriculture has been implemented or not. According to the analysis results, the average score of all the farmers was 63.9 out of the full score of 100 which can be seen to be a medium to high standard. Also, in the diagnosis results according to whether environmental friendly agriculture has been implemented or not, the ability scores of farmers practicing environmental friendly agriculture were higher than those who were not, but large differences between the item scores for information ability and cooperative ability were shown. This is connoting a very important meaning in terms of the point that correspondence is being made to the conditions required to possess market response capabilities to the high information systemization society to unfold in the future. As a result, the important issue can be seen to be personnel cultivation in order to possess self response capabilities through the development of education programs that can improve this kind of managerial ability and revision of support systems.

        신입 구급대원의 현장경험에 대한 현상학적 연구

        이기웅,길양숙 사단법인 인문사회과학기술융합학회 2018 예술인문사회융합멀티미디어논문지 Vol.8 No.1

        이 연구에서는 초임 구급대원(소방공무원)의 경험을 현상학의 연구방법으로 살펴보았다. 연구에 참여한 사람은 재직기간 1년 6개월 미만인 구급대원 6명이었으며, 이들과 1시간에서 1시간 반 정도씩 1~2회의 면담을 실시하였다. 연구 자료는 Colaizzi의 질적 자료 분석 방법을 사용하여 분석하였다. 연구 결과 초임 구급대원의 경험은 다양한 어려움과 보람으로 규정되며, 그런 경험을 요약하는 주제들은 다음의 일곱 가지로 요약되었다: 주 처치자로서의 부담감, 직무에 대한 책임감, 구급출동의 두려움, 현장경험과 직무능력 부족, 열악한 근무환경, 교육(코칭) 받을 기회 부족, 구급활동에 대한 인정. 이런 결과에 기초하여 어려움을 해결하기 위한 대책으로 인력 보충, 1급 응급구조사와 일정 기간 근무하기, 정례적 심리상담, 인사이동 없이 일정 기간 근무하기 등이 제안되었다. 이 연구결과는 초임 구급대원으로서의 적응이 외롭고 지난한 과정이며, 심리적 부담이 커서 이들을 돕는 다양한 대책이 시급함을 보여주었고, 인력보충과 심리상담 외에도 직무 교육, 멘토링 등이 필요함을 시사하였다. This research explored the experiences of the newly-appointed fire fighters (paramedics) through phenomenological research. For the research, six paramedics who had less than one and a half years of experience were interviewed. Interviews lasted one to one and a half hours. Colaizzi’s method was used for data analysis. As results, the themes that summarize the experiences of beginning paramedics were found as follow: burden as a main paramedics, responsibility on the job, fear of dispatch, lack of experience and ability in first aid, poor working condition, lack of opportunity to get coaching, and finding one’s worth. For the solution, it was suggested that beginning paramedics work with the first-rate emergency personnel during the 1st year, regular psychological counseling, and work without personnel movement for certain period of time. The results of this research show that the adaptation as a paramedic is difficult and lonely process and the stress caused by this process is big. In addition, it suggests the necessity of mento, counseling to look for psychological difficulties, and various education to improve job ability.

        생육공간을 공유하는 소나무와 졸참나무의 수분 이용 전략 비교 분석

        이기웅,이보라,조낭현,임종환,김은숙,Lee, Kiwoong,Lee, Bora,Cho, NangHyun,Lim, Jong-Hwan,Kim, Eun-Sook 한국산림과학회 2022 한국산림과학회지 Vol.111 No.3

        본 연구는 한국 산림생태계의 주요 우점종인 소나무와 졸참나무의 수분 이용 전략을 비교·분석하기 위해, 2019년 3월부터 12월까지 경기도 포천시에서 시행되었다. 소나무(n=6)와 졸참나무(n=3)의 수액속밀도와 환경 변수인 대기 온도, 상대습도, 강수량, 순복사량, 토양수분을 측정하여 계절변화 및 환경 변수에 따른 수액 이동 특성을 분석하였다. 그 결과, 수종의 최대 수액속밀도는 생장 기간(5-10월)에 졸참나무가 소나무보다 2배 가까이 높았으며, 졸참나무는 9월에 소나무는 8월에 가장 높았다. 수액속밀도에 영향을 주는 주요한 환경 변수들은 포화수증기압차와 순복사량이었으며, 대기 온도는 영향을 주지 못했다. 이력현상 분석에서 소나무는 건조해짐에 따라 기공을 닫고 졸참나무는 여전히 기공을 열어두는 전략을 사용하는 것을 발견하였다. 수관전도도 역시 최대 수액속밀도와 비슷한 경향을 보이며, 졸참나무의 수관전도도가 소나무의 수관전도도보다 약 2배 정도 더 높았다. 본 연구에서는 두 수종의 수분 이용 전략을 비교 분석하였고, 더 명확한 기작의 이해를 위해 생리적 특성뿐만 아니라 형태적 특성에 관한 연구도 병행되어야 할 것이다. The study was carried out in Pocheon-si, Gyeonggi-do from March to December in 2019 to compare and analyze the water use strategies of two co-occurring tree species, Pinus densiflora and Quercus serrata, both native and dominant in Korea's forest ecosystems. Through seasonal changes, we measured environmental variables such as air temperature, relative humidity, precipitation, net radiation, and soil water content. Sap flow densities of P. densiflora (n = 6) and Q. serrata (n = 3) were measured, along with environmental variables. The maximum sa pflow density for Q. serrata almost doubled that of P. densiflora during the growing season, while the maximum sap flow densities in both Q. serrata and P. densiflora peaked in September and August, respectively. Net radiation and vapor pressure deficit, but not air temperature, were the major environmental variables significantly affecting sap flow density. Analysis of hysteresis revealed that P. densiflora exhibited isohydric behavior, while Q. serrata showed anisohydric behavior. Analysis of crown conductance revealed similar trends as sap flow density, i.e., the crown conductance of Q. serrata was twice that of P. densiflora during the growing period. The study compared and analyzed the water use strategies between two co-occurring species. To better understand the underlying mechanisms of water use, more research on both physiological and morphological traits are needed.

        폐 ITO 슬러지로부터 주석과 인듐의 분리·회수

        이기웅,김홍인,손현태,안재우,김용환,Lee, Ki-Woong,Kim, Hong-In,Son, Hyun-Tae,Ahn, Jae-Woo,Kim, Yong-Hwan 한국자원리싸이클링학회 2014 資源 리싸이클링 Vol.23 No.2

        폐 ITO 슬러지로부터 주석과 인듐을 분리하기 위해 염산 직접 침출방법과 환원 열처리($700^{\circ}C{\sim}1100^{\circ}C$)후 염산 침출방식을 고찰하였다. 폐 ITO 슬러지의 염산 직접 침출시 인듐의 침출율은 18.5%이고 주석의 침출율은 19.95% 이었다. 한편, 폐ITO 슬러지를 수소분위기하에서 $700^{\circ}C$, $800^{\circ}C$, $900^{\circ}C$, $1100^{\circ}C$로 열처리한 후에 염산을 이용하여 침출시에는 주석의 침출율이 97% 이상으로 개선되었고, 온도가 $800^{\circ}C$일 때 침출율이 98.2 %로 가장 효과가 좋았다. 주석 및 인듐이 침출된 혼합용액에서 주석의 분리 및 회수를 위해 침전법을 사용하였다. 침출용액의 pH를 2.0으로 조절할 경우, 주석은 99.69%가 침전되었으나 인듐은 10.3%만 침전되어 상호분리가 가능하다는 것을 확인하였다. In order to separate Indium and Tin from spent indium tin oxide (ITO) sludge, direct hydrochloric acid leaching and thermal reduction followed by HCl leaching were applied. In case of direct leaching of spent ITO, leaching rate of In and Sn was 18.5% and 19.95%, respectively. Whereas, in case of thermal hydrogen treatment of ITO sludge at different temperatures such as $700^{\circ}C$, $800^{\circ}C$, $900^{\circ}C$ and $1100^{\circ}C$, followed by HCl leaching, we obtained the result of more than 97% leaching rate of Sn. Specially, thermal treatment at $800^{\circ}C$ showed the highest leaching rate of 98.2% of Sn. Precipitation method was used for separation and recovery of Sn from leached mixed solution. If the solution pH were adjusted 2.0, 99.69% of Sn precipitated and 10.3% of In was precipitated. This confirmed the possibility of separation of Sn and In from leached solution by precipitation method.

        문학 텍스트화와 언어-문화 공간의 토포스 : 러시아어 "프라브다" 토포스를 중심으로

        이기웅 서울대학교러시아연구소 2007 러시아연구 Vol.17 No.2

        The purpose of this paper is to explain the constructive function of the topas in the dynamic relationship between literary textualization and language-culture space. The term "topas" for Aristotle evokes either commonplace for validation of a certain type of language or common background for validation of a certain type of argumentation. But in the modern sense, it is propased to designate three different theoretical conceptions: stereotyped thematic structure(Curtius 1978), underlying general principle for inferenc(Anscombre and Ducrot 1983), normative axiom supporting socialized linguistic assignrnent(Rastier 1987). In this paper, I propose a synthesized version of topos by enlarging the applicability of Anscombre and Ducrot's idea that generally topos has an inferential form with gradual characteristic, e. g., "if more/less A, then more/less B". With appropriate modifications, their idea can be applied to Curtius's and Rastier's conceptions respectively. If topas has in principle gradual characteristic, it also has relative characteristic with reference to language-culture space; e. g., the topas of Russian лиса and that of English fox are the same, but those of сова and owl are different. From this it is evident that there are not only culture-specific topoi but also cross-cultural ones and that the particularity of a given language-culture space consists in its configuration of topoi in contrast with other configurations. With these considerations, this paper clarifies the topas character in the contents of the word правда which has been considered as one of the most typical cases that represent Russian national particularity. As a matter of fact, the topos of правда is a complex of two subordinate topoi; one is about the empirical attitude toward truth which can be considered as cross-cultural, and the other is about its moral justification which regards "compassion" as the highest principle; it is the latter part that makes the notional complex whole of правда so peculiar to Russian culture. If the literary text as a connotative system(Helmslev 1971) is intended to produce the effect of veridiction, this правда tapas can function as meta-tapas or meta-principle for the literary figuration which creates singularities on the basis of various topoi in the Russian language-culture space, because the connotative veridicality of such a creation and its communicative force depend largely on the fact that, according to the правда tapas, it constructs figures by selecting, combining and determinating topoi with originality but without distorting them.
