The purposes of this study are as follows. The first is to understand Dosan's thoughts on human and the background of his times. The second is to find out Dosan's basic thoughts and educational ideas. The third is to find out his educational contents and teaching method by considering Dosan's educational ideas. The fourth is to understand the specific realization of Dosan's educational thoughts. The fifth is to obtain what his thoughts suggest in connection with modern education. The conclusions of this study are as follows. 1) Born as a farmer's son, Dosan lead himself into the growth of the thought of nationalism after meeting Phil Dae-yeon, a senior pioneer and took part in the independence movement as a member of independence association and an orator. His thoughts on human consists of four factors 誠(sincerity), 愛(love), 勇(bravery), 智(knowledge) - with all of them in harmony. 2) Dosan's basic thought is to enlighten the nation and rear power and put an importance on personality and responsibility. He made it an educational aim to bring up a person with a whole character and a power as a way of making the nation powerful. All the things from above considered, his educational aim is the education of a whole man. 3) Dosan made an effort in bringing up a patriot with good personality for the nation's self independence and prosperity. He was a philosopher of education who emphasized these educational ideas- Musil(to make an effort to be sincere and true), Yokhang(to try one's best to perform), Loyalty, Bravery and practiced them for the independence by means of the national enlightenment and self innovation. 4) Dosan's educational content is to discipline a whole character and a sacred unity. He suggested four spirits-Mushil, Yokhang, Loyalty, Bravery-and three discipline factors-virtue, physical training and knowledge (he put a focus on virtue). The sacred unity training means cooperation, trust acquirement and justice discipline for common goal. (Dosan emphasized the necessity of national unity). The discipline of democratic citizenship means self responsibility and self sacrifice for the nation. His educational method is 'Eloquence', 'Dialogue', 'Models by living', and 'The way of making citizen brave and tender'. He used the Eloquence and the Dialogue as a way of enlightenment to make the whole nation feel the necessity of moral consciousness, world trends and the new culture. The practice of his educational thought could be found out not only in school education but also in social education (Jumjin, Deasung and Dongmyung school was the example of school education). 5) Next things are what the practice of his educational thoughts suggest in relation to today's education. First of all he emphasize to foster an expert with ability and power and following is to have a sense of responsibility. Finally he think it is important to aim at a whole man with a whole character. Therefore Dosan's educational thoughts are connected with the idea of human education which Korean education has pursued for the purpose of bringing up a man with ability in the information society of the 21 century and Korean with a good personality.

표면 처리를 통한 Organic Thin Film Transistor(OTFT)의 성능 개선

이상백 동아대학교 대학원 2002 국내석사

본 논문에서는 Pentacene(펜타센)을 활성층으로 사용하는 Organic Thin Film Transistor(OTFT)를 제작하여 전기적 특성을 조사하였으며, 성능을 향상 시키기 위해 소스 및 드레인 전극과 게이트 산화막 표면을 유기 단분자막과 산소플라즈마로 처리하였다. 펜타센 OTFT의 게이트 전극으로 p^+-Si 기판을 사용하였고 SiO_2를 열산화공정으로 성장시켜 게이트 절연막으로 사용하였다. 소스와 드레인 전극으로 Au를 증착하여 lift-off 공정으로 제작하였다. 펜타센 박막은 Organic Molecular Beam Deposition(OMBD)으로 증착하였으며, 펜타센 박막의 표면상태는 Atomic Force Microscope(AFM)으로 관찰하였다. 제작된 펜타센 OTFT는 P형 FET의 I_D - V_D 특성 및 전달특성곡선을 나타내었고, 특성곡선으로부터 성능지수들을 추출하였으며, 표면처리하지 않은 펜타센 OTFT의 전하이동도는 4.6x10^(-3) ㎠/V·s, 문턱전압은 -0.7V~V, Subthreshold slope은 0.5V/dec, 그리고 I_(on)/I_(off) 점멸비는 10^3으로 나타났다. OTFT의 성능향상을 위해 극성이 서로 다른 펜타센과 산화막 표면의 결합성을 증진시키기 위하여 SiO_2 표면을 자기조립 정열물질인 Octadecyltri chlorosilane(OTS) 처리하여 OTFT의 성능을 향상 시켰다. OTS처리 결과 전하이동도는 ~0.215㎠/V·s, I_(on)/I_(off)는 10^7, 문턱전압은 ~-1.4 V, Subthr eshold slope은 ~0.14 V/dec, 차단누설전류는 ~10^(-13) A의 값을 보였다, 또 전극과 펜타센 사이의 저항을 줄일 수 있는 물질 즉 2-Mercapto-5 -nitro-benzimidazole(MNB), 2-Mercaptobenzoxazolele (MBX), 2-Mercap tobenzothiazole(MBT), 2-Mercapto-5-methylbenzimidazole (MMB) 이 4가지를 이용하였다. 이중에 2-Mercapto-5-nitro-benzimidazole (MNB), 2-Mercap tobenzoxazolele(MBX) 두 물질을 이용하여 표면 처리한 OTFT의 성능이 향상되었다. MNB 처리 결과, 전하이동도는 ~0.05 ㎠/V·s, I_(on)/I_(off)는 10^4, 문턱전압은 ~-3 V, Subthreshold slope은 ~1.7 V/dec, 차단누설전류는 ~10^(-9) A의 값을 보였으며, MBX처리 결과 전하이동도는 ~0.082 ㎠/V·s, I_(on)/I_(off)는 10^6, 문턱전압은 ~-2.8 V, Subthreshold slope은 ~0.89 V/dec, 차단누설전류는 ~10^(-11)의 값을 보였다. 자기조립(self-assembly)방식으로 소자 제작은 습식 공정으로 OTFT를 용매에 오랫동안 담가두어야 하는데, 이는 금속의 박피와 플라스틱과 같은 기판에 상당한 악영향을 미치는 등 공정상 어려움이 많다. 그러나 건식 공정인 O2플라즈마를 통해 어려움을 해결할 수 있다. O2플라즈마 처리 결과, 전하이동도는 0.068 ㎠/V·s이었고, I_(on)/I_(off) 점멸비는 10^7로 나타났다. 금속과 산화막을 동시에 처리하여 산화막에 향상된 펜타센 결정을 금속과 펜타센 사이엔 적은 저항을 얻어 더 높은 성능 개선을 얻고자 OTS와 MNB계열 유기물을 동시에 표면처리 하였다. OTS와 MNB 동시 처리 결과 전하이동도는 ~0.11 ㎠/V·s, I_(on)/I_(off) 는10^7, 문턱전압은 ~-0.6 V, Subthreshold slope은 ~0.3 V/dec, 차단누설전류는 ~10^(-11) A의 값을 보였고, OTS처리 후 MBX처리 결과 전하이동도는 ~0.0135 ㎠/V·s, I_(on)/I_(off) 는 10^6, 문턱전압은 ~-1.1 V, Subthreshold slope은 ~0.44 V/dec, 차단누설전류는 ~10^(-11) A의 값을 보였다. 그러나 OTS만 처리한 성능보다 좋지 못하게 나타났다 이유는 OTS, MNB, MBX가 서로 반응을 하여 성능이 개선되지 못한 것 같다. OTS와 MNB, MNX,의 처리시간 조절이나 다른 물질을 적용함으로써 OTFT의 성능을 더 개선하리라 본다. In this thesis organic thin film transistors using pentacene thin film as an active layer have been fabricated and the performance has been improved by surface treatment on source & drain contacts as well as the channel areas with O2 plasma and organic monolayer. The pentacene OTFTs were fabricated on Si substrate on which SiO2 layer was thermally grown with 1000Å. The source and drain contacts were made of Au and patterned by lift-off process. Pentacene thin film was deposited by OMBD (Organic Molecular Beam Deposition) system. The pentacene OTFTs produced p-type FET characteristics in I_D-V_D and I_D-V_G curves. The performance parameters were extracted from the measured transfer characteristics. The as-deposited pentacene OTFTs without any surface treatments generated the performance as the followings; field-effect mobility of 2.6x10^(-3)~6.3x10^(-4) ㎠/V·s, with a threshold voltage of -2.57 V ~ -3.78 V, a subthreshold slope of 1.09 ~ 1.91 V/dec, and an I_(on)/I_(off) ratio of 10^4. In order to improve the performance the surface of Au contacts and channel area were treated by O_2 plasma and several organic materials such as OTS (octadecyltrichlorosilane), MNB(2-mercapto- 5-nitro-benzimidazole), MBX(2- mercaptobenzoxazolele), MBT(2- mercaptobenzothiazole), MMB(2-mercapto-5- methylbenzimidazole). OTS was self-assembled only on the SiO2 channel and drastically improved the performance that is a field-effect mobility of 0.215 ㎠/V·s and an I_(on)/I_(off) current ratio of about for the OTS-treated devices. OTS-treatment especially increased the mobility 100 times larger than that of the as-deposited OTFTs. The surface treatment with MNB and its derivatives on Au source and drain contacts reduced the contact resistance while the mobility was not much changed. Especially, MNB- and MBX-treatment was effective in improvement of contact resistance. The performance parameters of OTFTs treated by MNB and MBX were a field-effect mobility of 0.05 ㎠/V·s and an I_(on)/I_(off) current ratio of about 10^4 for the MNB-treated devices. and a field-effect mobility of 0.088 ㎠/V·s and an I_(on)/I_(off) current ratio of about 10^4 for the MBX-treated devices. It has been fond that OTS-treatment improved the mobility while MNB- and MBX-treatment reduced the contact resistance. Thus, OTS and MNB or OTS and MNX were simultaneously treated on Au contacts and channels. OTS/MNB-treated OTFTs produced a field-effect mobility of 0.166 ㎠/V·s and an I_(on)/I_(off) current ratio of about 10^7. OTS/MBX-treated OTFTs generated a field-effect mobility of 0.056 ㎠/V·s and an I_(on)/I_(off) current ratio of about 10^2. The co-treatment with OTS and MNB or MBX was effective to improve the mobility and the contact resistance simultaneously although the mobiity was not increased to the level of OTS-only-treated OTFTs. As an another approach O_2 plasma was applied to the contacts and channel area prior to deposition of pentacene thin film. The advantage of O_2 plasma treatment is dry process comparing with the wet process of the previous surface treatment which sometimes strip off the contact metals and gate dielectric layer especially in case of plastic substrate. OTFTs treated by O2 plasma for 8 minutes produced a field-effect mobility of 6.8x10^(-2) ㎠/V·s, with a threshold voltage of 1.3 V, a subthreshold slope of 0.59 V/dec, and an I_(on)/I_(off) ratio of 10^5. The performance was relatively lower than OTFTs treated by the organic monolayer. Finally, the fabrication process concerning on the performance improvement of pentacene OTFTs was studied and especially improved the mobility and on/off current ratio 100 times larger than the as-depsoited OTFTs. Therefore, it has been found that the organic monolayer deposition on the surface of source & drain contacts and channel was very effective process in pentacene OTFTs.

The efficient system of the marine logistic management is not established because of the various marine products distribution channels from production centers to consumers. More fresh marine products(Cold Chain) must be supplied for consumers because marine products become rotten with ease. To improve the maine products logistic system, the standard unit per cargo is required. The packing units of marine products vary with Pisces, and with the size even in the same Pisces. Also, the unified system of the total logistic acitvities-transportation, distribution, and stroage, and so on-is not established from delivery to warehousing of suppliers. The storage capacities of marine products, that is, equipment capacities of freezing, refrigeration room are in 12.7% short when considering production, imports, and exports of marine productions. Therefore, for efficiency and reasonable development of marine products distribution, the purpose of this paper is to seek the states of Korean marine products distribution and their problems, present its improvements. The functions of maine products logistic management are divided into transportation, storage, packing, unloading and information. Also these functions must be not in independent function by each but in intergration system linked to overall distribution system. The results of this study are as follows; First, in introduction of standard and Unit Load System of the packing unit, the automation and mechanization of transprotation, unloading and storage will be established. With the economic effects of ULS, personnel expenses and working times can be decreased. The operating function such as loading, storage and inventory management can be efficiency owing to the standard of all courses form packing to transportation, unloading, storage. Second, the competitive ness of small-medium refrigeration Co. should be promoted as co-operating the freezing-refrigeration equipments. Today the equipment size of the constructing freezing-refrigeration warehouse is larging. Thus the competitive ness of these firms is losing. As a example of Japan TOCP have been seen, 16 firms of small-medium freezing Co. establish co-refrigeration warehouse, manage the efficiency and reasonable management through co-loading working and co-management. Therefore we will reinvestigate the project of Kamchun's freezing-refrigeration equipment of exclusive pier for deep-sea fishing.

부동산개발사업에 있어서 프로젝트 파이낸싱의 활용방안에 관한 연구-민간 주도 프로젝트 파이낸싱 중심으로-

이상백 광운대학교 대학원 2007 국내석사

국내 부동산 개발 사업은 지역개발사업 및 사회개발사업을 포괄하는 개념으로 도시개발사업, 도시재개발사업, 노인주거시설 개발사업, 복합단지 개발사업, 국유지 개발사업 등이 있으나, 부동산 시장 및 분양시장의 활황으로 아파트, 주상복합 등 주거용 건축물 개발 사업을 중심으로 부동산 개발 사업이 점차 늘어나고 있으나, 정부의 부동산 시장에 대한 규제가 가속화됨에 따라 자연히 부동산 개발사업도 주거용 개발 사업을 중심으로 늘어나고 있는 실정이다. 그러나 주택시장 또한 침체로 미분양이 지속적으로 증가함에 따라 개발 사업을 진행 하는데 있어 분양성이 검증된 몇몇 선호 지역을 제외하고는 금융권의 자금조달이 어려워지고, 후분양 제도 도입으로 부동산 건설사들이 도산 및 주택보증회사가 부실해지는 등 부동산개발 금융시장에 급격한 환경변화가 발생하였다. 이로 인해 과거에는 부동산투기 등을 이유로 엄격하게 제한되어 왔던 금융기관의 부동산에 관한 대출이 1998년 한국은행의 「금융기관여신운용규정」의 개정과 신탁업법이 개정되면서 가능하게 되었고 아울러 IMF 경기침체에 따른 신규투자 축소와 부실기업에 대한 대출 제한 등으로 자금 운용에 어려움을 겪고 있는 금융기관과, 토지의 직접 매입에 따른 자금의 유동성 부족과 부채비율 상승을 우려한 건설사들이 토지매입과 사업시행을 목적으로 하는 별도의 SPC(Special Purpose Company)를 설립하여 시행과 시공을 분리하고자 하는 이해가 합치된 가운데 IMF 이후 국내의 사회간접자본시설의 투자수준이 적정 투자규모에 70%수준에 머물고 있는 실정이다. 우리나라기업의 매출액 대비 물류비의 비율이 선진국의 2배 이상이 된다는 것을 감안한다면 민간자본의 도입은 더욱 절실해지고 있다. 이러한 상황에서 국내 건설업체들도 기존의 단순도급형 수주형태에서 벗어나 보다 적극적인 형태로 사업에 참여하는 경향을 보이고, 이에 건설기업의 효율적인 자금조달 및 운용이 과제로 대두되고 있다. 이러한 상황에서 국내에서도 프로젝트 파이낸싱 기법을 도입․활용하는 시도가 늘어나고 있으나 IMF이후 출자자의 자금난과 금융기관의 소극성 등으로 원활한 파이낸싱이 부진하였으며, 사업추진 여건에 따라 부동산 개발사업에 있어 재원조달의 제한, 또한 정부주관 프로젝트의 파이낸싱사업은 정치적 고려요인 등이 반영되어 소극적․제한적 유인체계는 물론 수익성 보장이 미흡하는 문제점이 발견되었다. 따라서 본 논문은 이와 같은 부정적인 면과 문제점 해결방안으로 공공부문과 민간부문의 합동형 프로젝트 운영 및 다양한 금융재원 조달을 위한 프로젝트 파인낸싱 구상, 개발사업에 금융지원을 위한 제도적 보완, 민․관 합동형 프로젝트 파이낸싱의 사업구조 개선 등 민간 주도 부동산 개발 사업에서 동 금융기법을 적용하는 활성화 방안을 몇 가지 제시하였다.
