        A new air classifier with cut size smaller than about 10㎛, which allowed rapid classification to avoid the disturbance of particles reagglomeration, was designed and manufactured. The characteristics of the air classifier for fine powders was experimentally investigated. The results of the experimentation could be summerized as follows. 1) As the velocity of laden air was increased, the entrainment of fine particles into the coarse side was impressed.. 2) When the velocity of clean air was equal to the velocity of laden air, the sharpness index was good. 3) By sucking a portion of clean air into the fine side, the entraintment of fine particles into the coarse side was effectively suppressed. 4) The cut size and the classification performance were not affected by feed concentration up to at least 0.3kg/㎥.

Facing the issue of global climate change, it is important for educational community to help our students get the climate literacy with which to guide their own thoughts and decisions in a changing world. Therefore, climate change education is to help learners understand of their influence on climate and climate's influence on them and society. The purpose of this study was to develop the teaching materials for climate literacy cultivation in secondary school students. The results of this study are as follows. Firstly, The goal of climate literacy education is ‘to perceive the changing environment based on the phenomena of climate change, to the proposed plans for response and adapt to climate change through the cultivation of communication competence and the overall understanding about climate change through inquiry, and to keep practicing the proposed plans as a member of a community for global environment.' Secondly, contents of some programs and guidelines were compared and analyzed, and then fields of educational contents were created and items by fields were drawn out. The content system of climate literacy is composed of ‘principle of climate change science’, ‘climate change and human activity, ‘response and adaptation of climate change’. Thirdly, concrete content standards suitable for secondary school curriculum were suggested so that the goal and content system for climate literacy education.

      • 수평하중에 대한 말뚝 각부의 모멘트 분포

        In this paper, the behavior of single and pile groups under lateral load are studied through laboratory experiment. Model piles were made of brass pipe with outer diameters of 28.6mm, which are laid in loose, medium, dense sand of zigzag arrangement. The test results are as follows. As the increasing of relative density, the maximum bending moment is increased. The point of maximum bending moment on single pile measured at 5∼8B(diameter of pile) depth from surface, and group piles measured at 5∼l1B. The bending moment obtained by this experiment similiar with the one obtained by the Chang's theory.

        When we conduct environmental impact assessment, main contents consist of summary, project outline, environmental conditions, environmental impacts due to the project, mitigation devices, and alternative measures of harmful impact on environment. In this paper, to understand how they really conduct air quality impact assessment and prediction and examine their effectiveness, we considered the provisions and actual case of environmental impact assessment in Korea with that in Japan. As a result, we propose a method of improving air quality impact assessment and prediction, such as reflection of the result in environmental impact assessment, detailed assessment focused on relatively important environmental impact elements, field measurement investigation over four season and seven sucessive days, the uniformity of units, the proper model development to predict environmental concentration and a biennial environmental impact assessment for ex post management.

      • 용수 재이용을 위한 소규모 오수처리시설의 UV 소독시설에 관한 연구

        Deterministic and probabilistic approaches to the design of ultraviolet disinfection system for water reclamation are reviewed and discussed. The high inactivation of total coliform (TC), fecal coliform (FC) and Escherichia coli (E. coli) by UV disinfection was demonstrated, and the inactivations of TC, FC and E. coli were 97%, 98% and 99%, respectively. Within the range of 0.3∼0.4m Ws/cm, the effect of UV does on the inactivation ratio was not observed. However, in the highest wattage of UV lamp, 39W, the inactivation ratio of TC, FC and E. coli was 100%, regardless of the UV does so the UV density was more effective on inactivation ratio of TC, FC and E. coli rather than UV does. Under the 0.4 mWs/cm and 16W of UV lamp, the effect of dissolved organic matter and turbidity on the inactivations of TC, FC and E. coli could not be observed in this study within the range of 0∼32mg/L and 0-40 NTU, respectively. The effect of suspended solid is Tc, FC and E.coli observed liner equation y=305.03x-3697, y=186.14x-2509.5, y=152.96x-1976.5(r^=0.51, 0.69, 0.80) respectively. Suspended solid is the most important factor for design of the UV disinfection system.

We selected potato, pear, corn, banana and apple with natural broth media, respectively. The results investigated for new resource are as follows. The optimum temperature for mycelial growth ranged from 23~29℃, optimum temperature 26℃. The optimum pH ranged from 5.0~6.0, optimum pH 5.5. The carbon source contents were effective in 5~20% glucose almost identical., The nitrogen source peptone was higher growth in the 0.5~2.0% than 0.1%. For 5 weeks incubation, Natural substrates broth from banana, potato and corn grew better than pear apple, respectively.

      • 활동면을 가진 모래지반에서 무리말뚝의 수평거동특성

        It is well known that some of piles are subjected to lateral earth pressures due to lateral soil movements, such piles are called as passive piles. Because the lateral behavior of pile in a group is developed by many factors involved in their deformation and strength characteristics, the mechanisms of the passive pile is not completely clarified yet. This paper describes a series of model tests on instrumented pile groups embedded in HAP-CHEN sand undergoing lateral movement, the extent of the group effect on the lateral response of a pile in a group was found to be dependent on a number of factors, including the position of the pile in a group, the pile spacing, and the pile arrangement.

      • 혈관 내 폐보조장치에서의 압력손실 예측

        The purpose of this study was making a equation to predict relationship between pressure drop and frontal area in 40% glycerol solution at 37 ℃. Before using whole blood, we estimated pressure drop with experimental equation, and compared the results with experimental results. Also, we tried to make module design that contained the maximum number of hollow fiber membranes in 3㎝diameter tube. We have observed pressure drop of 40% glycerol solution flow rate in each modules that have been changed by the number of the hollow fibers, and studied about the equation related between flow rate and pressure drop, friction factor and Reynolds number. The results showed that the pressure drop which was calculated with the various frontal area was similar to the pressure drop of using the equation obtained from the experimental. Also, the maximum number of hollow fiber is 675, which can be inserted in 3㎝diameter tube when the out side of diameter was 380㎛. It satisfied pressure drop(<15㎜Hg).
