In this paper an attempt was made to establish a direction in systematizing the technical education with regard to the relation to environmental education. This study was made mainly through literature review concerning the relationship between technology and environment, and thus this study has a purpose of connecting the contents of technical education with environmental education. It will provide referential data for environmental education. The main text of this study dealt with which goal to establish in the technical education from the viewpoint of academical position considering the relationship between technical education and environmental education. Also, it dealt with the organization of contents of environmental education according to the 7th curriculum and, as a result, it reached the following conclusions: In the first place, technology and environmental education which have close relationship with each other should be considered in the developmental aspect. In the second place, technology, in any directions, affects natural environment. In the third place, environmental education should be done by the integrated approach and one of the alternatives can be through SET education including society and culture, environment, and technology all together. In the fouth place, the environmental education should be environmentally sound and developed sustainably so that the technology can be developed along with environment. One example can be found in the ecological architecture. In the fifth place, the environmental education which is a souce of technical education has its necessity in 8 aspects. In the sixth place, according to the 7th curriculum, the following can be the teaching contents which will connect technical education and environmental education: gardening, vegetable raising, planting and trimming, the future techniques, energy and transportation techniques, and so on. In the seventh place, the technical education can have seven goals concerning environment. In the eighth place, the environmental education in the technical education should be considered in the aspect of contents, of teaching and learning, of evaluation, and of the relations with subjects. In the ninth place, should be included as teaching materials of the units of technology textbooks where environment education will be dealt with.

Though electricity consumption amount in industry has been increased gradually, corresponding power supply show symptoms of marginal point. Importance of demand-side management from large-industries has also been raised. This paper deals with induction motor, which is one of representative examples of heavy electricity consumption utilities, to analyze potential technical capability, economic feasibility from consumers' viewpoint and demand-side management feasibility from nation-wide perspective. Nation-wide economic feasibility analysis was done through California test, which has been used as demand-side management evaluation model. This paper also describes limitation of existing high efficiency induction motor in terms of contribution to demand-side management and utilizes premium motor to calculate demand-side management contribution level and economic feasibility evaluation. Likewise, this paper emphasizes the efficiency improvement of induction motor and analyzes how much premium motor related technologies can contribute to demand-side management.

Construction period is longer than the non-disclosure in civil construction of apartment house. And this process is intensive at the beginning and end of construction. Because this project management expertise is required. Nevertheless, subsidiary work(Working avoid a tendency of advanced technician, Frequent turnover and employment contracts, etc.) management attention of construction is at a lower level. Because of, there are the bad factors(trial and error, finish degradation, etc.). Therefore, this study analyzed Hindrance Factor of quality control on apartment complex construction work and presented importance of civil construction engineer's role. Also, forms of civil construction engineer, Performance experience and technical Strength of apartment complex construction was investigated for the construction. To this end, It analyzes the relationship between forms of civil construction engineer, Performance experience and technical Strength of apartment complex construction and Construction of evaluation as required by Construction Technology Management Act.

In the consumer products industry, it has been highly desirable to develop objective test methods to replace subjective evaluation methods. In developing an objective test method, subjective evaluation data should be on a linear scale. According to Thurstone's theory of comparative judgment, a%-preference from a paired-comparison test can be converted to a linear-scale value. The required number (N) of paired-comparison tests increases dramatically as the number of products increases. This problem should be solved by classifying the total products into several subgroups consisting of 3-4 products in each group. By doing so, it can not only significantly reduce the number of required paired-comparison tests, but it can also obtain more reliable, reproducible data.

Because of its advantages such as more safe better electrical properties, lighter and easier to handle etc. than conventional ceramic materials, the development and application of composite insulator to the distribution and transmission system have been rapidly increased lately. In this paper, we reviewed performance evaluation on composite hollow insulator for extra high voltage based on IEC 61462 Technical Report 2, prospected to be published as international standards of Insulator for $SF_6$ GIS, Transformer, Arrestor etc, having been prepared by IEC technical committee 36 : insulator.

A new test method has been developed for a quantitative evaluation of macro-stickies in recycled pulps. The method uses a fine slot screen to separate a sticky particles form fiber in the pulp samples. The obtained sticky particles were spread on filter paper and covered with silicon carbide powder in order to make the stickies area with sufficient contrast between stickies and background. The stickies are then counted by a scanner-based image analysis system. The validity of this evaluation method of stickies of KOCC, ONP and white ledger wastepaper recycling plants respectively. It is shown that this method can be applied for a quantitative determination of stickies content in various recycled pulp samples. With this testing method, reproducible and reliable data were obtained for the actual mill pulp samples.

WCT (Wet compaction test) is a new fiber evaluation method developed recently by Seo and its test results can be used as a predictor for pulp quality and its paper property Bleached chemical pulps (SwBKP, HwBKP), recycled pulp (OCC), and mechanical pulp (BCTMP) were used for the furnishes to be tested by WCT We compared the WCT results to conventional fiber evaluation tests such as WRV (Water Retention Value), free ness, and fiber length in this study, and found that WCT always gave better regression coefficients in relation to pulp quality (drainage), and paper properties (density, tensile, tear, and burst strength). WCT may be used on-line in papermachine.
