KADS 지식모델의 의미론

전윤재 한국경영과학회 1994 한국경영과학회지 Vol.19 No.2

KADS is currently a best known methodology for expert system development in Europe. KADS world sees the expert system development as a modeling activity and uses models to control complexity of the development process. Four layered KADS expertise model is used to describe expert knowledge. But this expertise model in high abstraction level is conceptual and not formalized. This paper has formalized KADS expertise model using set theory and mathematical semantics combined in order to reduce the ambiguity of informal models of expertise, provide a precise means of communication about the model of expertise and point out incompleteness and inconsistency of the model of expertise. Instead of first order predicate calculus, set theory and mathematical semantics are used because they are a more general and have compositive quality.

정영라,전윤재 대불대학교 2002 論文集 Vol.8 No.1

The purpose of this paper is to develop an instruction model of information communication for a cooperative problem-solving type class based on the education information policy to be adapted for the overall subjects on the curriculum with a view to make teachers instruct the students at any class-hour through PC communication. In this regard, this paper surveyed the information mind-set among teachers, proposed a design of hardware/software instruction model for a cooperative problem-solving type class, and adapted the cooperative programs-solving instruction in the active classroom. The detailed study procedure is as follows, First, the survey is made on the relevant documentation and the actual school condition. The documents referring to the information education, such as the administrative guidelines by MOE, reports on the model teaching, research documents of these sorts are collected and analyzed to find the actual condition of the information education on school sites. And the information mind- set among teachers in Kwangju area are questionnaired on their involvement in electronic teaching system as from the year of 2000 to the first term of the information education project. Second, as for the teaching under the information communication technology (ICT), the teaching and learning model is proposed to be adapted in the development of the class utilizing ICT. The paper discussed a design of the class with ICT network environment equipped with multimedia hardware for educational use and proposed a cooperative problem-solving teaching system to be utilized in schools so that teachers and students can use the various educational software as developed in the following five steps of procedure as in assigning problems → collecting relevant data →analyzing findings → presenting results → evaluating the outcome rather than that steps of conventional procedure as in introduction → development → consolidation. Third, based on the previous model procedure, a teaching method is developed to be adapted in the school and demonstrated in the active class situation with the information communication environment. The students-initiative leaning was confirmed as they took the initiative in solving the problem, which was an uncommon class activity to be found in the conventional type of teaching and learning. In conclusion, the orientation of education should be reestablished in the education information age of the twenty first century as is the case that the student's learning attitude was active one with the reedited contents of textbook. In order to meet the requirement of the problem-solving teaching as proposed in this paper, an information communication network environment is designed for the existing classroom and a teaching and learning procedure is proposed for the student- initiative problem-solving learning. For the batter practice of the proposed hardware/software design, more computer system should by provided with in the classroom to be utilized by teachers and students to increase the efficiency of teaching and leaning.

문태홍,전윤재 대불대학교 2003 論文集 Vol.9 No.1

In the 21st century, the information-oriented society, the high value-added information industry is the main part. To gather information comes true mostly byusing computer. The Art Education is much influenced by ICT teaching skills of using computer etc. The Art Education is the human eduaction through the art. The Art Education is not only to instruct students formative skills and cultural knowledge but also to cultivate humanism that beautifies and improves our environment by raising a sense of beauty and developing creative genius. If the learning contents are provided appropriately, diversely, repeatedly by using ICT in Art Education just the same, that can be one of the useful methods for learners to get to the goal of learning. As the contents developed by many teachers are input to the teaching-learning step according to the appropriate input time, the effect of learning can be built up. When the teaching-learning activity is performen in school, it reaches the limit in the method of cultivating the aesthetic attitude feeling and enjoying the beauty because of the limitation in time and place, the distinctive quality of the Art Education. Teacher should provide the visual information to the students and guide them in searching it for themselves. Now, however, the care of the learners with this character leaves much to be desired. In this study, the presentation and the homepage are applied to the expression learning, the homepage to the appreciation field (the art history), the computer graphic is input to the class in the design expression area, students can solve the problems and just know the answers on line using data site and cafe site in evaluation. As the developed ICT is applied to the some units, the easy reading presentation is effective for the expression learning and the induction of learning motive, and the learning using Internet is good in the part of the appreciation and evaluation. And as a large majority of the students take an more interest in the Art Education because of the teaching-learning method using ICT, that is introduced the effective teaching-learning method to the Art Education.

김수목,전윤재 대불대학교 2002 論文集 Vol.8 No.1

The appearance and improvement of computer and informational communication have made every industry develop fast, and computer education at school have played an important role. Computer education at vocational schools should be focused at developing its students' abilities to adapt themselves to society because it is closely related with their social life. The reason is that the computer education demanded by society affects the country's development directly. The purposes of this study are to find out the problems of the computer education at vacational schools, to study the desirable ways for the education, and to help the vacational education bring up many specialists needed in modern society. I have studied computer educational theories from many papers and books, and analyzed the educational states of 10 vocational high schools in Jeonnam Province through 40 teachers and 193 students. The efficient ways of computer education at vacational schools acquired from this study are like these; First, it should be allowed for teachers to use the text books developed by themselves in computer classes. And it is necessary to encourage them to develop practical texts. Second, the practical education should be given to students so that they may get qualifications with which their abilities will be recognized by society after graduation. Third, training courses for computer teachers should be done consistently and systematically, which can make them obtain the most advanced computer knowledge and apply it to their teaching. Fourth, new computer curriculum and teachers' training courses would not improve the quality of education, if educational program were not developed and spread widely to educational field. Fifth, many instruments for a quality computer education should also be supplied. Above all, various class should be done with the necessary facilities through the research for the demand of computer surrounding. To achieve these, the financial support of the government, the positive attitude and concern of the school, and the teachers' efforts are needed.

오현권,전윤재 대불대학교 2003 論文集 Vol.9 No.1

Appearance and development of information using computer and communication network have extended the use of computer in the whole areas of society and all aspects of our society have been rapidly developed. Therefore this study aims to extens rice farming management, farmland dealings, long-term lease of farmland and farm management scale through compensation project, enhance agricultural competitiveness by collectivizing farmland, attract young people to rural ares and developspecialized and large-scaled farmland management system by means of computer programs related to services and management of rural areas in order to cope with environmental changes of rapidly changing information system. This study examines the actual conditions of special rice farmhouses and standarduzed farming project, presents their problems, seeks activation methods and reviews mid-and long-term plans of special rice farmhouses and standarduzed farming project. Theoretical inquiry of rice farming management and standardized farming project is based on preceding papers and literatures and evaluates analysis of existing projects' results and their validity. Future directions of rice farming management and standardized farming project obtained by this study are as follows; First, as the initial goals for cultivating special rice farmhouses over 100,000 houses, 60,000 farmhouses having more than 3 ha and 40,000 farmhouses since 1995 showed, there was a problem that it focused on achieving the target number of farmhouses rather than supporting potential farmhouses and the extension and absorption of rice farmhouses having more than 3 ha into institutional circle should be examined actively to support compretitive farmhouses and enhance the effects of standardized farming project. Second, farmhouses having farmland less than 2ha were selected as special rice farmhouses and have had supports, but it is judged that special rice farmhouses having farmland less than 2ha must not have supports to enhance the achievements of supports for special rice farmhouses. Third, upper limit of current support unit price and appropriateness and improvement methods of allotment system are expected and support unit price ahould be decided by considering the appropriate allotment level and beneficiary's level and a possibility of collecting credit incurred by insolvent obligation should be considered. Fourth, one of important conditions to develop smooth standardized farming project is to secure enough farmland.
