  • 1989년에 NCTM에서 Curriculum and Evaluation Standards for School Mathematics(이하 Standards)를 발간한 이래로 수학교육은 Standards의 정신에 많은 영향을 받아왔다. 90년대의 수학교육은 학생들의 수학적인 문해능력(literacy)의 중요성을 반영하여 학생들이 수학의 가치를 느끼도록 하며, 자신들의 수학적 능력에 대해서 확신을 가지게 하며, 수학적인 문제해결자가 되도록 하며, 수학적으로 의사소통하는 것을 학습하며, 수학적으로 추론하는 것을 학습함으로서 아동들에게 수학적인 힘을 길러주는데 중점을 두고 있다. 특히 수학적 의사소통능력은 학생들의 수학적인 힘을 기르는데 매우 중요하다. 아동들의 수학적인 의사소통 능력을 향상시키기 위해서 교사는 아동들이 상대방의 아이디어가 받아들일 만한 것인지에 대해서는 비판하고 토론을 하도록 하되 발표한 사람을 비난하는 일이 없도록 각 학급에서는 의사소통과 상호작용에서의 사회적인 규범과 사회-수학적인 규범이 형성되도록 해야 할 것이다. 이런 규범을 바탕으로 교사와 학생이 협력함으로써 서로의 아이디어에 대해 원활한 의사소통을 이룰 수 있다. 그래서 무엇보다 중요한 것은 문화공동체로서의 교실내에 의사소통을 촉진할 수 있는 규범을 형성하는 것이라고 할 수 있다. 이런 규범은 교사 혼자의 노력으로 이루어지는 것이 아니라 교실 구성원 전체의 상호작용에 의해서 장시간에 걸쳐서 형성된다고 할 수 있다.

  • Additive manufacturing technology is recognized as an optimal technology for mass-customized distributed production because it can yield products with high design freedom by applying an automated production system. However, the introduction of novel technologies to the additive manufacturing industry is generally delayed, and technology uncertainty has been pointed out as one of the main causes. This paper presents the results of the research and analysis of current standardization trends that are related to additive manufacturing by examining the hierarchical structure of the quality system along with the various industry and evaluation standards. Consequently, it was confirmed that the currently unfolding standardization does not sufficiently reflect the characteristics of additive manufacturing technology, and rather can become a barrier to entry for market participants or an element that suppresses the lateral shearing ability of additive manufacturing technology.

  • The curriculum differentiation is supposed to maximize individual strength and possibilities of the students, and to maximize educational efficiency by differentiating the instructions according to students' abilities, aptitudes, needs and interests. The Ministry of Education has suggested a stepwise model for school mathematics. This model is named "Stepwise Curriculum Differentiation"(段階別 敎育課程 差別化). In this paper, we would like to make a specific proposal for the 7th curriculum. Our proposal reflects fully the guidelines of the Ministry of Education. It is also based on the national curriculum history up to the present time. It could be used as a reference for the continuing work of curriculum reformation. We suggest dividing the contents of mathematics for 1-10th graders into about 15 steps, to use the step-based textbooks instead of the grade-based ones, and to prepare evaluation standards for each step. We also suggest that the classes for grades 11-12 be organized according to their optional courses and/or their steps.

  • The Technical Proposal Tendering system is recognized as an ordering means with the most reasonable merits for the construction projects, however, many evaluation standards and hearing procedures are applicable to the conventional method. Because the possible cost reduction of construction works is highly estimated, it is possible to induce the cost reduction. But the excessive shortening of works period has raised a variety of problems such as concerns on poor construction due to the valuation on the contributed performance improvement and the shortening of works period. Accordingly, after investigating the processing and ordered status on the Technical Proposal Tendering and sorting out problems based on existing researches, this study estimated important problems and analyzed each gradual one through the rate of importance. The results diagnosed the possible CM application as a means to solve major problems of technical proposal bidding.

  • The purpose of this study is to investigate the present status of environmental education administration in the middle schools of Seoul City and to find problems to be solved environmental education in middle schools. To accomplish these purpose surveys for middle school teachers in Seoul was conducted, and evaluation reports of school environmental education of 1998 were analyzed. The results indicated that both schools and Ministry of Education offered few evaluation standards related to environmental education. Most schools abolished division of environmental affairs because of the reorganization of school system, which focuses on subject and aptitude-based education. In addition, environmental education and related activities were maily the responsibilities of division of science education. The teachers responded that such activities as organization and management of mothers'social service, management of environment day, use of environmental conservation card, and establishment of conservation area were not effective and should be abolished. The conclusion from this study are that environmental education can be effective only when goals of environmental education are included in school evaluation, and the division of environmental affairs should be revived and systematically operated in school.

  • Nowadays, housing density in a city is getting higher, and this trend is expected to continue in the future. Therefore, Skyscraper is considered as future alternative architecture beyond symbolic meaning in aspect of demand and supply of urban land. However, skyscrapers which were newly built in Korea have many problems such as consumption of enormous amounts of energy, destruction of natural environment, and traffic jam. And from now on, environment-friendly development of skyscraper is urgently needed. However, plans or evaluation standards, which take account of the environment-friendly aspect of skyscraper, leave much to be desired. And especially it is hard to find environment-friendly skyscrapers. Therefore, this study aims to find realistic alternative solutions of environment-friendly skyscraper through analysis of the works of Ken Yeang who has been known as bio-climatic architect and tried to apply environment-friendly plans to skyscraper.

  • Appraisal format is the methods that is used to gether informations related to performance behaviors. Appraisal format has descriptive characteristics including evalustion dimensions, anchors, scales. The purpose of this paper is to study the effectiveness of a format characteristics of the appraisal results through literature review and to explore more approprate appraisal format through comparing three types of formats, graphic scales, BARS, BOS. According to the results, rating format's characteristics can affect the quality of appreisa results in that appraisal format can provide rators with evaluation standards which help raters to evaluate effectively. Specific dimensions are better than gernal one dimension. The effectiveness of scale in some degrees depends on development procedure. In general anchors are important to reduce rating errors and behavioral anchors are better than numeric anchors, The systematically developed BARS and BOS can reduce rating erros but graphic scales has limitstions.

  • The aim of this paper is to investigate how the public procurement policy exerts an effect upon the technology innovation of the firm and to make alternative proposals how to reinforce the effect. Although the pubic procurement process based on its monopsonic idiosyncrasy implies the means to lead the firms' supply function, the present system has contributed a little to accelerate the technology innovation. In fact, the system is lacking of the evaluation capability referring to the technological computer among the bidding films. So as to reinforce the function of technology innovation of the public procurement policy, it is necessary to improve the procurement institutions, in particular bidding and contract system. Finally, the paper propose, on the on hand, to enlarge the application range of the total bidding system in order to apply more strictly the technology evaluation standards on bidding, and on the other hand, to multiply the competitive proposal and the incentive contract type.

  • This is a basic study designed to discover the most comfortable thermal environment for Korean residences. The purpose of the research is to observe and measure the summer thermal environment in Korean urban detached single family houses and apartments by utilising proposed evaluation standards and methods. The technique used involves the measurement of environmental elements, such as indoor temperature, relative humidity and radiant temperature both in detached single family houses and apartments. Also, in order to understand the resident's thermal comfort response. ASHRAE' thermal sensation 9th level, indoor temperature 5th level, and thermal discomfort 4th level in the psycho-physical voting scale (1972) was used. In conclusion, among Korean urban residences, detached single family houses provided a more stable thermal environment than apartments, as shown by physical psychological evaluations. The possible reason for such stability in detached single family houses may be the usage of reinforced concrete structures which maintain consistent temperatures.
