최근 보건의료 분야와 정보통신 기술이 접목된 u-Healthcare에 대해 원격진료 제한을 완화하는 의료법 개정안이 입법 예고되면서 u-Healthcare 수요 창출을 위한 비즈니스 모델로 IPTV를 이용한 서비스가 등장하였다. 하지만, 의료서비스에 IPTV 기술을 도입함으로써 환자의 치료방법의 개선, 서비스 질의 향상, 치료의 효용성 증가 등의 많은 이점들이 예상처럼 도입되고 있지 못하고 있는데, 이는 아직 정비되지 않은 법, 제도적 환경뿐만 아니라 사용자 수용 연구를 통한 전략 마련이 부족했음을 인정하지 않을 수 없다. 본 연구는 IPTV를 통해 제공되는 의료서비스를 수용하는데 있어서 연결되는 순차적인 관계를 검증하고, 분석된 결과를 토대로 IPTV 기반 의료서비스의 활성화 방안을 제시하였다. 연구 결과 IPTV 기술 품질의 편의성, 콘텐츠 품질의 완결성, 그리고 Healthcare 서비스 품질이 만족도를 이끌어 내는 주요 요소들로 추출되었고, 전반적으로 IPTV 기술 품질, 콘텐츠 품질, Healthcare 서비스 품질 모두 만족도에 유의한 영향을 미치는 것으로 분석되었으며, 본서비스의 만족도는 사용의도에 유의한 영향을 미치는 것으로 나타났다. As the Korean Ministry for Health and Welfare announced the likelihood to revise the legislative limit for healthcare telemedicine, u-Healthcare service through IPTV emerged among these business models. However, in spite of many advantages such as treatment improvement, service quality enhancement, and treatment usefulness, most medical trials grafted with IT have not accepted yet. This points out not only that law and institutional environment has not prepared, but also that policy maker neglect the preparation of the strategies through the study on user acceptance. The purpose of this study is to verify the relationship for IPTV quality based Healthcare on satisfaction and intention to use. The results identify that IPTV technology quality for its convenience, contents quality for its completeness, and the quality for healthcare services give significant effect to satisfaction. In addition the study indicates that overall qualities of IPTV technology, contents, and healthcare service, significantly impact on satisfaction respectively and that the satisfaction may lead to the intention to use of this service.

This research explored Plato's Philosophical roots far the lifelong learning, In this study four research questions were examined. 1.What Kinds of historical backgrounds did the conception of Plato's lifelong learning have? 2.Did Plato add any metaphysical arguments to support his system of thought concerning lifelong learning? 3.How did Plato outline the educational sequence and what kinds of relationships did the sequence have with the lifelong learning? 4.Did Plato's Academy provide any meanings for the lifelong learning? The findings of those inquiries will be summarized by analyzing and evaluating the evidences presented in this study. 1) Plato developed theories of lifelong loaming in the fourth century. Those held that the most complete happiness for man was achieved only through continuous study over a life time. He built upon the groundwork laid by Socrates, who had emphasized lifelong learning. He set up some metaphysical foundations in order to reason such a system of thought. He outlined a specific sequence of studies to develop the power of reasoning, and established institution wherein students and scholors could pursue learning for an indefinite period of time. 2) Plato's metaphysical pattern justified that the rational side of human soul was the highest and made a man a real human being. He believed that the soul was the knowledge of mental form and an essential one because the soul was immortal. The human beings who were rational could come closest to the gods by recalling some knowledges of mental form that existed prior to experience. He also believed that a philosopher could arrive at the highest and absolute form after the lifelong learning. 3) Plato insisted that some learnings made a philosopher orient to an absolute idea. He thought that learning should be emphasized in one's childhood and that telling some stories, and teaching gymnastic were essential to boys, He believed that learning mathematics was good for helping the young's mental discipline and abstract ideas and that subject matters such as arithmatic, geometry, astronomy and music could assist young minds prepare for philosophical learnings. Plato thought that subject matters such as dialetic and logical reasoning should be taught after having studied mathematics and one could study philosophy after fifty. He emphasized that the study of philosophy should pursue throughout a complete span of life. As a result the philosopher had to study up to the deathbed. 4) Plato insisted that the degree of happiness reached during one's life was determined by the level of finding one's lifelong learning span. Only lifelong learning would determine the happiness for man. He emphaszed that the school academy was the place where scholars could achieve the most complete happiness by the endless study. Although the philosophers could participate in the political affairs of the state, the democracy of Athens did not permit their roles. Even though the philosophers of that age recommended the directions of the policies for the real politicians, the Academy established by Plato became a refuge from the democratic form of government. Concluded from above Plato supported the lifelong learning and pioneered philosophical roots of the lifelong learning by analyzing and enhancing the human mind.

철강산업의 온실가스 배출 탈동조화 국제비교

김동구 한국환경경제학회 2022 자원·환경경제연구 Vol.31 No.1

The iron and steel industry is a manufacturing industry with the largest greenhouse gases emissions and has a great ripple effect on the national economy as a core material industry. This study internationally compared the decoupling patterns of greenhouse gases emissions in the iron and steel industry from 1990 to 2019, focusing on Korea, Japan, and Germany. In particular, unlike previous studies that considered only fuel combustion emissions, this study considered all fuel combustion emissions, industrial process emissions, and indirect emissions from the use of electricity and heat. As a result of the analysis, Korea is interpreted as expansive coupling, Japan as decoupling, and Germany as unclear. Therefore, the decoupling path that the Korean iron and steel industry should take should not be in Germany, but in the form of seeking a decoupling method similar to Japan or more effective than Japan. In addition, this study considered the characteristics of the iron and steel industry as much as possible and presented the causes of the decoupling analysis results and implications for the Korean iron and steel industry through comparison with Japan and Germany. In particular, four factors were suggested as factors which has promoted decoupling in Japan: high value-added of Japanese iron and steel products, development of energy efficiency technology in the Japanese iron and steel industry, strategic M&A of the Japanese iron and steel industry, and maintaining competitiveness according to the closed distribution structure of Japanese iron and steel products. The Korean iron and steel industry should also use the case of Japan as a benchmark to further increase added value through quality uprade and product diversification of iron and steel products, while at the same time making efforts to fundamentally reduce greenhouse gas emissions through the development of new technologies. 철강산업은 온실가스 배출량이 가장 많은 제조업이면서 핵심소재산업으로서 국민경제에 미치는 파급효과가 크다. 본 연구는 한국, 일본, 독일을 중심으로 1990~2019년 기간에 걸쳐 철강산업의 온실가스 배출 탈동조화 양상을 국제비교하였다. 특히, 연료연소 배출량만을 고려한 선행연구들과는 달리 본 연구에서는 연료연소 배출량, 산업공정 배출량, 전력 및 열 사용에 따른 간접 배출량을 모두 고려하였다. 분석결과, 한국은 확장적 동조화, 일본은 탈동조화, 독일은 불분명으로 해석된다. 따라서 한국 철강업이 나아가야 할 탈동조화 경로는 독일이 아니라, 일본과 유사하거나 일본보다 더 효과적인 탈동조화 방안을 모색하는 형태로 진행되어야 할 것이다. 또한, 본 연구는 철강업의 특성을 최대한 고려하고 일본 및 독일과의 비교를 통해 탈동조화 분석결과의 원인과 한국 철강업에의 시사점도 제시하였다. 특히, 일본의 탈동조화 촉진 요인으로 일본 철강재의 고부가가치화, 일본 철강산업의 에너지효율기술 개발, 일본 철강산업의 전략적 M&A, 일본 철강재의 폐쇄적 유통구조에 따른 경쟁력 유지, 4가지를 제시하였다. 한국 철강업도 일본의 사례를 벤치마크로 삼아 철강재의 품질 고도화 및 품목 다변화를 통해 부가가치를 더 높이는 동시에, 신기술 개발을 통해 온실가스를 근본적으로 줄이기 위해 노력해야 할 것이다.

중학교 도덕교육의 헤겔주의적 분석

김동구,지봉환 서원대학교 교육연구소 2003 敎育發展 Vol.22 No.2

In this study, some moral education contents in Korean middle school were compared with those of Hegelianism. For the exploration, Korean moral textbook in middle school and Hegel's Grundlinen der Philosophie des Rechts were analyzed. In this study, three criteria for comparison, home, society and nation were selected. In the field of home management the similar positions between Korean moral textbooks and Hegel's philosophy were the essence of love and function of education. Three different views existed between them. Korean textbook dealt with traditional home ethics, family member's role and passive moral education, while Hegel emphasized some processes of deciding home ethics, social relations with family members and positive moral education together with negative conditioning. In the domains of social relations Korean textbooks suggested some disposition to dehumanism, materialism and egoism as social problems. Hegel also pointed out similar social problems in moral education. Korean moral textbooks postulate that individuals give rise to serious problems and the problems can be solved through the recovery of the individuals morality. Hegel however maintained that the social problems are brought about not by individual but by ill-balanced relations between individuals and their society, and the problems could be resolved by the coordination between and among them. On the relations between individuals and nation, Korean textbooks as well as Hegel maintained that democracy was the best policy. Korean textbooks explain that individual ideals and goals were more important than national roles. However Hegel thought that there should be interactive relations between individuals and nation.

MTMS와 TMES로부터 제조된 코팅 도막의 발수성에 미치는 촉매와 용매 종류의 영향

김동구,이병화,송기창 한국화학공학회 2019 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.57 No.6

Methyltrimethoxysilane (MTMS) and trimethylethoxysilane (TMES) as starting materials were dissolved in various types of solvents, and hydrolysis with water and polycondensation reaction were carried out using various types of catalysts to prepare non-fluorinated water-repellent coating solutions. The coating solutions were spin-coated on cold-rolled steel sheets, and thermally cured to prepare water-repellent coating films. The effect of types of catalysts and solvents on the water repellency of the resulting coating films was investigated during this process. When hydrochloric acid and nitric acid, which are strong acids, were used as catalysts, the solutions showed a white opaque state due to the aggregation of siloxane polymers. On the other hand, when acetic acid, phosphoric acid, and oxalic acid, which are weak acids, were used, they were in a stable and transparent state without precipitation. As a result, the contact angles of the coated films, prepared from hydrochloric acid and nitric acid, were 58o and 92o, respectively, showing low water repellency. On the other hand, when acetic acid, phosphoric acid, and oxalic acid were used, the contact angles of the coated films were 101o, 103o and 116o, respectively, showing high water repellency. In addition, when isopropanol and ethanol were used as solvents, phase separation occurred in the solutions due to the aggregation of siloxane polymers. On the other hand, when methanol, ethyl acetate, and methyl ethyl ketone were used as solvents, the solutions were transparent and showed a stable state without sedimentation. Methyltrimethoxysilane (MTMS)과 trimethylethoxysilane (TMES)을 출발물질로 사용하여 여러 종류의 용매에 용해시킨 후 다양한 종류의 촉매를 사용해 물과의 가수분해 및 중축합반응을 진행시켜 비불소계 발수 코팅 용액을 제조하였다. 또한 이 코팅 용액을 냉연 강판 위에 스핀 코팅하고 열 경화시켜 발수 코팅 도막을 제조 하였다. 이 과정 중 촉매와 용매의 종류 변화가 생성된 코팅 도막의 발수성에 미치는 영향을 연구하였다. 강산인 염산과 질산을 촉매로 사용한 경우에는 용액 내에 siloxane polymer들의 응집이 발생한 흰색의 불투명 상태를 나타냈다. 반면에 약산인 아세트산, 인산과옥살산을 사용한 경우에는 투명하고 침전이 없는 안정한 용액 상태를 보였다. 이로 인해 강산인 염산과 질산을 사용한경우의 코팅 도막의 접촉각은 각각 58o와 92o로 낮은 발수성을 보인 반면에 약산인 아세트산, 인산과 옥살산으로 제조된 경우에는 각각 101o, 103o, 116o의 접촉각을 보여 높은 발수성을 나타내었다. 또한 이소프로판올과 에탄올을 용매로사용한 경우에는 용액 내에서 siloxane polymer들의 응집이 일어나 불투명한 침전이 발생한 상분리 현상을 보인 반면 메탄올, 에틸아세테이트와 메틸에틸케톤을 용매로 사용한 경우에는 투명하고 침전이 없는 안정된 상태를 나타내었다.
