The study aims to present learners-oriented critical education in teacher-centered critical education methods. Learner-oriented critical education is the consideration of the characteristics and individual differences of the learners in existing teacher or theoretical criticism. Criticism is a judgement of value on aesthetic objects. Therefore, value judgement is part of the decision-making process. Therefore, in order to be a learner-centered review, the type of decision making on aesthetic objects must be considered. In this study, learners' decisions were divided into intelligent, emotional, and dependent types. Because criticism is a decision-making process, presenting different methods of criticism for different types of decision-making is a realisation of learner-centered critical education. Art can be largely divided into creative and critical activities. There are many ways to apply creative activities to educational sites. The most representative method is to apply the contents and methods of the creation differently depending on the characteristics of the learners. This selection and application of content and methods created according to the characteristics of the actual learner has many educational effects. However, the critique activity still applies to the external conditions of the learner, such as a teacher or critique theory, rather than the characteristics of the learners performing the criticism. Therefore, this study was intended to present the method of critical education according to the characteristics of the learners in the Critic activities, as practical education approaches according to the characteristics of the learners in the Practical Activities. 이 연구는 교수자 중심의 미술 비평 교육 방법에서 학습자 중심의 비평 교육으로 전환되기 위한 방안을 제시하고자 한다. 학습자 중심의 비평 교육은 기존의 교수자나 이론 중심 비평에서 학습자의 특성과 개인차를 고려하는 것이다. 미술의 주요 활동인 창작 활동과 비평 활동이다. 이 중에서 미술 창작 활동은 이미 학습자의 표현 특성에 따라 창작의 내용과 방법, 평가 방법을 상이하게 적용하여 접근하고 있다. 학습자의 표현에 대한 흥미와 적성에 따라 교수자가 창작하는 내용과 방법, 평가를 다르게 교수하는 것은 개별화 교수에 기여하며, 학습자의 배움과 성장에 도움이 되고 있다. 하지만 비평 활동은 아직까지 비평을 수행하는 학습자의 특성보다는 교수자이거나 비평 이론 등의 조건에 따라 비평 교육이 이루어지고 있다. 그래서 본 연구에서는 학습자의 비평 유형에 따른 적절한 비평 모형을 제시하고자 한다. 이를 위해 본 연구에서는 학습자의 유형을 지성형, 감성형, 의존형으로 구분하고 이를 진단하기 위한 질문지를 개발하였다. 또한 기존의 미술 비평 방법을 학습자의 의사 결정 유형에 맞게 재구성하고 수정하여 제시하였다. 이를 통해 기존의 의사결정 유형인 지성형, 감성형, 의존형으로 학습자를 구분하고 이들 유형에 따라 가장 적절한 미술 비평 방법을 적용하여 비평 교육에서 개별화 교육을 실현하고, 학습자의 성장과 배움이 될 수 있도록 하였다.

최한기의 기학(氣學)을 통한 인물의 서체 해석과 미술교육: 주권상실기의 서체를 중심으로

이화식,박명선 한국조형교육학회 2014 造形敎育 Vol.0 No.49

본 연구는 일제침략기의 반일과 친일이라는 두 가지 대립적인 집단을 제시하고 그들의 인성적 특성을 서체와 혜강(惠岡) 최한기(崔漢綺)의 기학(氣學)을 통하여 분석, 해석하였다. 최한기는 조선 후기의 대표적인 실학자로 세상과 인간의 본질을 기(氣)로 해석하였다. 그는 인간의 본질을 기의 작용으로 파악했으며 오구(五具)와 오발(五發)이라는 기준을 제시하여 평가하였다. 이와 같은 최한기의 인간관과 필적을 토대로 본 연구자는 반일의 인물 4명()과 친일의인물 4명을 분석․해석하였다. 민족과 국가의 시련기의 반일과 친일의 집단은 단순히 반일과친일이 아니라 선공후사(先公後私)와 선사후공(先私後公)의 대표적인 경우이고 친일의 선사후공은 홍익인간의 관점에서 위태로운 개념일 것이다. 그러므로 개인의 인성적 특성이 어느 정도 서체에 반영된다는 것은 다른 의미로는 서체를 통하여 개인의 인성적 특성을 어느 정도바꿀 수 있다는 중요한 단서이다. 그래서 개인의 인성적 특성이 서체에 반영되고 서체를 통한 인성 교육의 방향을 제시하는 것이 매우 의의가 있는 연구이다. This study suggested two conflicting groups of anti-Japanese and pro-Japanesein the Japanese invasion period. The study analyzed and interpreted personal traitsof the members of the two groups based on their writing styles and the study ofKi(氣) by Choi Han-gi(崔漢綺). Choi Han-gi is a representative scholar of Silhak(實學), the realist school of Confucianism, in the late Joseon Dynasty, whoconstrued the nature of the world and human as Ki, the internal energy. Choiinterpreted human nature as a function of Ki and evaluated the nature based onthe five basic elements of individuals(五具) and five ways to express theelements(五發), the principle that he suggested. With his view of man and writingstyle, this study analyzed and interpreted four people from the anti-Japanese groupand four people from the pro-Japanese group. The groups under the national timeof trial were not just anti or pro-Japanese but represented people who prioritizedpublic interests over private affairs(先公後私) and vice versa. The priority onprivate affairs over public interests(先私後公) by the pro-Japanese group can beregarded as a perilous idea from a humanitarian perspective. In this regard, thefact that individual’s personal trait is reflected, to some extent, in the writing styleof the person is a critical evidence showing that the writing style of an individualcan change personality of the person. Therefore, this is a very significant studythat individual’s personal traits can be reflected in the writing style and suggeststhe direction of personal education through writing style.

치기공과 임상실습교육 실태 조사

이화식,배봉진,박명호 대구보건대학 2005 대구보건대학 論文集 Vol.25 No.-

This study was conducted by collecting and analyzing curricula of 19 colleges that has the department of dental laboratory technology throughout the country and analyzed by use of a questionnaire designed by the researcher with regard to details of actual operation in each college. Credit points for clinical training that has been conducted based on curricula vary from 3 to 20 points depending on colleges. But around 10 credit points are considered as ideal. For evaluation, the evaluation table was not applied but used as reference only. As criteria for evaluation such as evaluators, evaluation items and criteria for point distribution do not provide objectivity or reliability, development of accurate evaluation tools is required. It dis necessary for the bodies of colleges to maintain a level of mutual trust by visiting the sites of practical training regularly for the formation of progressive industry-academia cooperative relationships. When selecting the sites of practical training, it would be desirable to look for sites with better conditions for practical training in conjunction with related institutions. Besides, regarding clinical training education, in order for students to adapt themselves correctly to work environments and rapidly cultivate practical capabilities at site, systematic and efficient operation of training sites is required.

1. Conclusion As this study aims at seeking a new direction in the curriculum for training the dental technicians in our junior colleges, we first of all gathered and analy3ed the information on the educational systems of the vocational colleges in the foreign countries and their national qualification systems for the dental technicians, along with the present curriculums for the dental technicians course in the various colleges in the advanced countries such as the United States, Canada, West Germany and Japan. After making an analytical comparative study and evaluation of these materials with the help of the questionaire, the advice of the members of the industrial-educational cooperation, of Korea Dental Technicians Associations Association, and the consultation of Korea Faculty Association of Dental Technology, we developed a new curriculum for training of the better dental technicians in our junior vocational colleges. In view of the present vocational education of the dental technicians in our junior colleges, it is very much desirable to develop a new curriculum for the dental technology students in order to give them a proper education in the concerned field. Therefore, in the course of developing this new model curriculum, a careful consideration is given to the selection of teaching subjects, the allocation of class and experiment (including the field training) hour, and the effective transition in guiding students. This means that he or she as a dental technology student should get a proper education which gies a high a high professional knowledge as well as a thorough and good technical skill. 2. Suggestion 1) In order to promote efficiency of education of the dental technicians, the standardization of teaching subjects and their names is required. 2) In order to improve the technical skill of the dental technicians all the necessary machinery and tools are to be fully equipped, so that they can easily make effective adaptation what they learned in colleges to the practical work. 3) In order to strengthen the industrial-educational cooperation system, the practice of the field work should systematically be carried out. 4) According the insearch of the information of the educational system, the course of the dental technicians should be extended from the present two years to over three or four years in order to make the dental technique scientific as well as technic. 5) As a part of the supply and demand of the manpower of the dental technicians they should have an opportunity to be employed in the public health center, in the industry of manufacturing mental materials, and in the various firms of selling the dental materials along with the dental laboratory and the general hospitals. An opportunity for the dental technicians to go to the overseas should be given by the government channels. 6) A reasonable measurement of the supply and demand of the manpower of the dental technicians should be taken by the government and the readjustment of the number of the students in the department of the dental technology of the respective college is very much required.

Reformatory school was changed into the school for custody, personality, subject, vocational education from the school for caring and custody as revising the law of reformatory school on December 31, 1988. The reformatory school is divided into schools for personality education, subject education, and vocational education again. Although reformatory school is divided into schools as each function, the center of reformatory school should be personality education. Even though it is true that personality education in reformatory school is criticized because they handle and plan personality education without deliberation and detailed review, they positively use art program as an important tool of personality education, but they also have the process without clear character and purpose. Analysis of arts programs for personality education in the field has been somewhat formally said that. Analyzed the nature and content of arts programs for personality education have chose. So, the study clarifies understanding personality education in training school, and what character and purpose art program should have for personality education. Through the study, I would like to help evaluate, select the method of teaching and learning, pick up the contents of forming art education program in the field.

The use of low-noble dental alloys in densitry has increased with the rising price of gold. A decrease in the noble metal content of such fairly complex alloys easily results in multi-phase structures. Dental Ag-Pd-Cu alloys exhibit the characteristics of age-hardenabifity. Palladium represses the sulphurization of silver, and the age-hardenability is caused by the addition of copper. In order to improve the corrosion resistance, a small amount of gold is added to the commercial alloys These alloys were melted and casted by induction electric furnace and centrifugal casting machine in AK atmosphere. They were rolled and drawn into plate and wire shape. These specimens were solution treated for 2hr at 800 C and were then quenched into iced water, and aged at 350-550℃ Microstructural characteristics of the small Au-containing Ag-Pd-Cu dental alloys were investigated by means of electron microscope observations, emergy dispersed spectra and electron probe microanalysis, and dental application was carried out by corrosion test. Principal results are as follows : It was very effective that addition of small amount of Au increased corrosion resistance in Ag base dental alloy and increasing the Pd content of Ag base alloys also increased corrosion resistance. The formation of the lamellar structure developed from grain boundaries by discontinuous precipitation. Lamella structure will contribute more to corrosion resistance and is prone to high corrosion rate.
