        이종기 대구대학교 2005 국내박사

        RANK : 247631

        As increasing the use of the Internet and improving the technologies for the Internet based applications, the uses of e-Learning have been also increased and the effectiveness of e-Learning have become one of very important issues practically and theoretically in both education engineering and information systems. This study suggests a research model, called e-Learning success model, for evaluating effectiveness of e-Learning based on information systems success model, constructivism and self-efficacy. The e-Learning success model focuses on learning environment and learners' self-efficacy. The former consists of learning management system, learning contents and interaction that are provided by e-Learning and the latter means learners' self-regulatory efficacy and computer self-efficacy. In addition, we suggest another research model for sensitivity analysis of the relationship between quality factors and satisfaction in e-Learning environment. We show validity of the model empirically. In result, most of all hypotheses suggested in this model are accepted in low significant level.

      • 초등학교 도덕·국어과에 반영된 순종의 효 연구

        이종기 성산효도대학원대학교 2006 국내석사

        RANK : 247631

        우리 겨레는 예로부터 동방예의지국이라고 칭송을 받을 정도로 효를 중요시하고 우리의 전통가치 중 가장 으뜸의 덕목으로 여겨 실천해왔다. 그러나 서구적 자유민주주의와 평등사상이 만연된 오늘날 오랫동안 가정과 사회윤리로 확립되어 왔던 전통적 효는 산업화에 따른 사회 병리 현상과 서구 교육으로 인한 가치관의 혼란으로 인해 크게 흔들리고 있으며 특히 초등학교에서 민주시민으로서의 품성과 자질을 함양하기 위한 인성교육과 예절교육 측면에서 심도 있는 효 교육의 연구가 부족한 실정이다. 이러한 관점에서 본 연구는 보편화 가능성이 높은 효 윤리 체계 중 ‘순종’을 중심으로 구축하여 설명하고 이와 같은 관점에서 초등학교 어린이들에게 맞는 보편화 가능성이 높은 체계적인 효의 개념을 고찰하고 새로운 효 윤리 체계를 바탕으로 초등학교 도덕, 국어과 교육과정에 나타난 효 교육 내용과 방법을 분석하고자 하였다. 도덕성 발달의 주요한 시기인 초등학교 어린이들에게 적합한 효 교육방법을 규명하기 위하여 보편적인 분석의 틀을 구축할 가능성이 있다는 관점에서 보편화 가능성의 효 윤리체계를 ‘순종’을 중심으로 설명하고, 서양의 종교와 효에 관한 내용을 중심으로 제시하였다. 또한 초등학교 도덕, 국어과 교육과정에 나타난 효 교육내용을 보편화 가능성의 효 윤리 체계에 의해 분석하였다. 초등학교의 경우 읽기를 통해 효를 이루는 근본을 알고 실천할 수 있는 바른 태도, 자식을 기르는 부모님의 사랑과 자식을 염려하는 부모님의 마음, 부모님의 자식에 대한 사랑과 보살핌, 효의 근본인 부모님의 사랑과 은혜에 대한 고마움, 친애의 효를 비롯하여 부모님을 그리워하는 마음과 스승과 웃어른의 가르침을 실천하는 마음 등을 지니도록 지도해 나가야 한다. 초등학교 도덕, 국어과 교육과정에서 거의 모든 학년이 각 단원에 걸쳐 효와 관련된 내용이 고루 제시되고 있으며, 모든 학년에 공통적으로 효 교육과 관련된 지문 외에도 ‘순종’과 관련된다양한 그림 자료를 통하여 효 교육 내용을 구성하고 있다. 이 중 ‘순종’이 효 교육 교수-학습 시간의 46% 이상에서 다루어지고 있으며, 이를 효의 가장 기본으로 생각하고 있다. 교수-학습 과정에서 있어 효의 당위성을 강화하는 교사의 노력이 필요하며, ‘순종’의 효 지도가 조기에 효과적으로 이루어져야 한다는 것이다. 또한 초등학교에서 교과 시간에 다루어지지 못하는 부분의 효를 교육하기 위해서는 7차 교육과정의 특징인 재량활동 시간을 이용하여 지도하는 것이 바람직하다. 초등학교의 효 교육은 보편화의 가능성이 높은 효 윤리 체계를 순종을 중심으로 설명하고 이와 같은 관점에서 초등학교 어린이들에게 맞는 체계적인 효의 개념을 고찰해야 한다. 제7차 초등학교 도덕, 국어과 교육과정에 나타난 효 교육내용을 파악하고 학년 및 학기별로 이를 분석하여 학년 수준에 맞는 적절한 효의 지도 방향을 알고 실천해 나가야 한다. 또한 전통적 효 교육의 한계를 극복하고 오늘날 새로운 효의 논리와 효 교육체계를 정립하기 위해서는 보편화 가능성의 효 윤리체계를 수용해야 할 필요가 있다. 효 교육 내용적 측면에서 보면 먼저 교육과정에서 효 교육이 차지하는 비중을 높여야 한다. 효 교육의 비중을 높이는 방법으로는 가치, 덕목간의 통합 교육으로 비중을 높일 수 있다. 다음으로 보편화 가능성의 효 윤리체계의 네 가지 변수와 관련하여 효 교육내용 및 제재를 고르게 선정하여야 한다. 끝으로 효 윤리의 역할을 확대해야 한다. 부모와 자식 간의 윤리에서, 이웃, 사회, 국가, 인류의 윤리로 그 역할의 확대가 필요하다. 효 교육방법적 측면에서 먼저 통합적 교육방법의 도입이 필요하다. 국어, 사회 등 다른 교과에서 효 교육에 대한 내용과 도덕 교과의 효 교육이 함께 이루어진다면 효 교육의 효과는 증대 될 것이다. 다음으로 교수-학습 방법의 다양화가 필요하다. 시대의 흐름을 고려한 정보통신기술과 놀이를 도입한 다양한 교수-학습 방법이 요구된다. 또한 효 교육은 학교, 가정, 사회 모두가 관심을 가지고 서로 긴밀한 협력 관계를 유지하면서 이루어 져야 한다. 보편화 가능성의 효 윤리체계를 바탕으로 시대에 맞게 재구성된 효 교육은 자라나는 세대들에게 효의 가치를 일깨워주고 효를 실천하게 하는데 도움을 줄 수 있을 것으로 본다. Korean people have valued filial piety and considered it as the most precious virtue among traditional values so that they were praised as the country of courteous people in the East. However, with the spread of Western liberal democracy and idea of equality, the traditional filial piety which has long been established as home and social ethics is in a seriously shaky state due to social pathology caused by industrialization and confusion in values caused by Western education; in particular, in-depth studies on filial piety education are scarce in terms of personality education and etiquette training to cultivate character and disposition as a democratic citizen in an elementary school. From this point of view, this study aimed at constructing and explaining 'obedience' among the filial piety ethics system which can possibly be generalized, considering the systematic concept of filial piety which can be generalized to elementary school children, and analyzing descriptions and methods of filial piety education in the elementary moral education and Korean curricula based on the new ethical system for filial piety. To determine a filial piety teaching method suitable for elementary school children who are in the important period of morality development, this study described the filial piety ethics system which could be generalized to construct a universal analysis framework on the basis of 'obedience' and principally presented descriptions of Western religions and filial piety. This study also analyzed descriptions of filial piety education in the Korean curriculum according to the filial piety ethics system which can be generalized. In an elementary school, it is necessary to teach children to get right attitudes to understand the foundation of filial piety and practice it, parental love to rear children and parental mind to be anxious about children, parental love and care of children, gratitude for parental love and favors, longing for parents including affectional filial piety, and the will to practice teaching by teachers and seniors through reading. Almost all grades have descriptions related to filial piety evenly in each of units for elementary moral education and Korean curricula; all grades commonly have composition of filial piety education through various figures related to 'obedience' in addition to relevant descriptions. Of these, 'obedience' makes up over 48 percent of the teaching-learning education for filial piety and is considered as the most fundamental virtue of filial piety. It is therefore necessary for teachers to reinforce inevitability of filial piety in the teaching-learning process and to teach filial piety of 'obedience' effectively at the early stage. To teach filial piety which fails to be dealt with during regular classes in an elementary school, it is also desirable to use the class for discretional activities which characterizes the seventh curriculum. Filial piety education in an elementary school should focus the filial piety ethics system which can possibly be generalized on obedience; from this point of view, it is necessary to consider the systematic concept of filial piety suitable for elementary school children. It is necessary to understand and analyze descriptions of filial piety in the seventh elementary moral education and Korean curricula by grades and terms to determine and practice the good instructional direction for filial piety suitable for each school year. To overcome the limitations of traditional filial piety education and establish new logics and educational systems for filial piety, it is necessary to accept filial piety ethics system which can be generalized. As for the quality of filial piety education, it is first necessary to raise the share of such education. This can be possible by integrated education of values and virtues. Next, it is necessary to select contents and materials of filial piety education evenly in relation to four variables of the filial piety ethics system which can be generalized. Finally, it is necessary to expand the role of filial piety ethics. The role should be expanded from ethics between parents and children to include ethics of neighbors, society, countries, and human beings. As for educational methods for filial piety, it is first necessary to introduce integrated educational methods. If other subjects including Korean and social science deal with filial piety in addition to the education through moral education, the filial piety education will be more effective. Next, it is necessary to diversify teaching-learning methods. A teaching-learning method is necessary which introduces information and communication technology and play in consideration of temporal current. It is also necessary for all of school, home, and society to take interest in filial piety education and maintain closely cooperative relationship. It is therefore necessary to construct a filial piety education system through association among school, home, and society. Filial piety education reconstructed on the basis of the filial piety ethics system which can be generalized will be helpful in making the young generation understand the value of filial piety and practice the value.

      • 電子部品 flux 除去用 水系 洗淨劑의 相擧動과 洗淨力 硏究

        CFC-113 and 1,1,1-TCE have been widely used solvent for the removal of organic flux residues in the fabrication of circuit boards in electronics and precision instruments manufacturing industries. After CFC-113 and 1,1,1-TCE, known to be an ozone depleting substances(ODSs), the use of which have been strictly limited by the Montreal Protocol and the Clean Air Acts. Therefore, the development of alternative cleaners to CFC-113 and 1,1,1-TCE is indispensable. In this study, the phase behavior of ternary systems, containing nontoxic and biodegradable polyoxyethylene alkyl ether(POE alkyl ether, AEO) nonionic surfactant, water and D-limonene, were studied to develop new alternative cleaners. The result showed an oil-in-water(O/W) microemulsion in equilibrium with excess oil phase at low temperatures and a water-in-oil(W/O) microemulsion in equilibrium with excess water phase at high temperatures. For intermediate temperatures a three phase region containing excess water, oil and a middle-phase microemulsion was observed. Single phase microemulsion was observed at high concentration of surfactant. The single phase microemulsion in nonionic surfactant system was confirmed as a W/O microemulsion by checking the electrical conductivity. Addition of butyl diglycol(BDG) and butyl triglycol(BTG) as cosurfactants lowered the temperature necessary for the formation of a three phase region and produced a middle-phase microemulsion over a wide range of temperatures and promoted formation of a microemulsion phase at lower temperatures. In particular, a small amount of n-propanol as a cosurfactant was found to be the most effective in extending a microemulsion phase region over a wide range of temperatures. The solubilization of abietic acid, triolein, and lubricant using three different types of microemulsions showed addition of a cosurfactant promoted the solubilization mainly due to a decrease in interfacial tension. Temperature sensitivity of a nonionic surfactant system was effectively relieved by addition of an anionic surfactant SDS. And the formation of one phase microemulsion was not affected by pH, water hardness concentration and addition of an antioxidation agent. The effect of solvent on microemulsion phase behavior and flux removal efficiency in systems containing commercial POE alkyl ether nonionic surfactant was investigated. The addition of a n-hydrocarbon as a solvent produced an O/W microemulsion phase over a wider ranges of temperatures and cosurfactant to surfactant ratios. Especially, the addition of n-hexadecane to the surfactant system, the most hydrophobic solvent among used during study, produced a microemulsion phase over a wide range of temperatures and promoted formation of a microemulsion phase at lower temperatures. Candidating formulations were determined from microemulsion phase behavior study and their cleaning efficiency was tested using a dipping method in the laboratory and pilot industrial cleaning test. All cleaner candidates showed excellent removal efficiency for abietic acid over a temperature range from 30℃ to 40℃ and also showed good effectiveness on a pilot cleaning test. These results shows that candidate formulations can be used as alternative cleansers of CFC-113 and 1,1,1-TCE and the phase behavior is a very useful tool to develop new alternative cleaners.

        Olefins react with ozone to give an intermediate of ozone-olefin adduct, which is very unstable and subjected to cleave into two key intermediates one of which is zwi-terion. The key intermediates react in various ways to give new organic materials. Thioethers, which is sulfurcontaining organic compounds, could be converted to sulfoxides and sulfons by the reaction of ozone due to nucleophilic property of sulfur compounds. The major goal of this research is to identify which materials are produced by the ozonation of 3-methyl- 1 - methylthio - 1 - butene, and dimethy Idisulfide. For this purpose, ozonations of 3-methyl-1-methylthio-1-butene and dimethyldisulfide have been carried out in n-pentane solution at - 78℃ and on the absorption of polyethylene powder at - 78℃, respectively. The results are as follows, (1) Reaction of dimethyldisulfide with bromine yields methanesul fonylbromide, and which is reacted to 3 -methyl - 1 -methylthio - 1 -butene with 3 -methyl - 1 - butene . The product yield was 60% and cis to trans ratio of this pro duct was 86: 14. (2) The major products of 3 -methyl - 1 -methylthio- 1 -butene in n-pentsne solution at - 78℃ were 3, 5-diisopropyl- 1, 2, 4 -trioxolane (yield 64.5%), 2-methylpropionicacid(9.5%) , 2 -methylpropionlcaldehyde (10.2%), dimethylthiosul fonate (3.5%) , and methanesulfonaldehyde (2.3%), and dimethydisulfide and formicacid were also identified to a minor ratio, However, 3,5-dimethylthio-1,2,4-trioxolane and 3-isopropyl - 5 - methylthio -1,2,4 -trioxolane which were expect ed to be produced accordin9 to Crie9ee mechanism, were not produced.
