  • The purpose of this study is to develop a plan that adopts a fairly tale motif, which is familiar to children, to traditional Korean costume design factors for the development of practical Korean costume enterprises, which lead the Korean costume industry in its existence. Literary research and previous research methods had been used in this study. After comparing traditional Korean costume factors with practical Korean costume factors through literary research, we examined children's Korean costumes and ordinary children costumes. The results of this study are the following: First, the result of literary research, which used traditional Korean costume as motif of practical Korean costume and adopted model factors that the developed motif had used, shows that the design factors of practical Korean Costumes have changed from traditional to modern, seeking practicability and convenience over appearance. Second, practical Korean costumes are suitable when fairy tale illustration is applied to children with curiosity and warm emotions, and towards children, who spend much time on activity during growth. Third, making use of CAD system, which is different from practical Korean costume based on traditional patterns and single color, and using various pint pattern with many stories for the design of practical Korean costumes, and applying diversity to the market of practical Korean costumes, this study provides new design motif from, which people can feel more familiar to practical Korean costumes.

  • 중 고등학교 현장 과학 교사들을 대상으로 7차 교육과정의 탐구 과정 요소의 활용 정도와 가설에 대한 교사들의 인식을 알아보기 위해 설문조사를 실사하였다. 조사 결과 교사들은 자료해석을 가장 많이 활용하였으며 다음으로 결론 도출을 많이 활용하였다. 가장 활용 빈도가 낮은 것은 가설 설정이었으며 다음으로는 자료 변환이었다. 이러한 결과와 더불어 교사들이 가장 활용하기 힘들다고 응답한 탐구 과정 요소는 가설 설정이었으며 자료 변환, 변인 통제가 그 뒤를 이었다. 가설 설정은 현장에서 활용 빈도가 가장 낮으며 교사들이 가장 활용하기 힘들어하는 탐구 과정 요소로 나타났다. 가설에 대한 교사들의 인식 조사 결과 많은 교사들(63.1%)이 가설에 대해 바르게 진술하였으나, 구체적인 문제 상황에서 가설을 바르게 선택하는 교사의 비율(5.0%)은 매우 낮게 나타났다. 현장에서 가설 설정 수업의 가능성에 대한 교사들의 인식 조사 결과 90%이상의 교사들은 중학교 이상에서 가설 설정 수업이 가능하다고 보았다. 그러나 실제로 과학교사들은 가설 설정을 현장의 과학 수업에 활용하는 것을 어려워하고 있음을 알 수 있다. 이러한 결과는 현재 중등학교 현장에서 거의 활용되지 않고 있는 가설 설정 관련 수업이 가설에 대한 적절한 정의와 수업 전략이 주어진다면 가능하다는 것을 의미한다.

  • 전형적인 농촌유역을 가지는 충남 아산시 마산저수지는 상류 유역으로부터 다량의 점, 비점오염물질이 유입되어 과영양 상태를 나타내는 농업용 저수지이다. 주요 유입하천인 황산천과 초사천의 수질('05년~'06년)은 TN과 TP 등 영양염류와 유기물의 농도가 매우 높은 수준을 유지하고 있으며, 이로 인해 마산저수지의 수질은 COD가 농업용수 기준을 초과하는 상태를 보여주고 있다. 이러한 저수지의 수질개선을 위해 저수지 유입부에 설치 및 관리가 용이한 조립식의 오염물질 침강장치를 개발하여 그 효과를 평가하고자 하였다. 그 결과 침강시설의 평균 정화효율은 부유물질(SS) 55.7%, 총질소(TN) 61.0%, 총인(TP) 55.9%로 장정렬등(2004)이 제시한 부댐형 침강지의 정화효율에 비해 안정적으로 높은 효율을 보였을 뿐 만 아니라 저비용으로 높은 수질개선 효과를 거둘 수 있는 경제적인 시설로서 저수지 수질개선에 효과적인 것으로 사료된다.

  • This technical paper deals the practical transformation algorithms between several lunar reference frames which will be used for Korea pathfinder lunar orbiter (KPLO) flight operation. Despite of various lunar reference frame definitions already exist, use of a common transformation algorithm while establishing lunar reference frame is very important for all members related to KPLO mission. This is because use of slight different parameters during frame transformation may result significant misleading while reprocessing data based on KPLO flight dynamics. Therefore, details of practical transformation algorithms for the KPLO mission specific lunar reference frames is presented with step by step implementation procedures. Examples of transformation results are also presented to support KPLO flight dynamics data user community which is expected to give practical guidelines while post processing the data as their needs. With this technical paper, common understandings of reference frames that will be used throughout not only the KPLO flight operation but also science data reprocessing can be established. It is expected to eliminate, or at least minimize, unnecessary confusion among all of the KPLO mission members including: Korea Aerospace Research Institute (KARI), National Aeronautics and Space Administration (NASA) as well as other organizations participating in KPLO payload development and operation, or further lunar science community world-wide who are interested in KPLO science data post processing.

  • Although the generic implementation of aqueous two-phase systems (ATPS) processes for the recovery of biological products has been exploited for several years, this has not resulted in a wide adoption of the technique. The main reasons involve the poor understanding of the mechanism governing phase formation and the behavior of solute partitioning in ATPS processes, the cost of phase forming polymers, and the necessary extended time to optimize the technique. In this review paper, some of the practical disadvantages attributed to ATPS are addressed. The practical approach exploited to design ATPS processes, the application to achieve process integration, the extended use for the recovery of high-value products, and the recent development of new low-cost ATPS, are discussed. It is proposed that the trend of the practical application of ATPS processes for the recovery of biological products will involve the purification of new high-value bioparticulate products with medical applications. Such a trend will give new impetus to the technique, and will draw attention from industries needing to develop new, and improve existing, commercial processes.

  • The practical shiphandlers, such as ship's captain, pilot and mooring master, in charge of the SBM app-roaches and mooring operations of loaded VLCC should have a highly advanced shiphandling skills because of taking advantage of the wind and current from ahead without assistance of big tugboats. But now except some approaching skills in the vicinity of SBM buoy or waiting anchorage we do not have an optimal controlled approaching maneuvers in the entire course of port approaches. Consequently this study presents the optimal SBM approaches to the practical shiphandlers of VLCC and puts to use with effect in the practical operations. The conclusions of this simulation study are as follows : 1) The optimal SBM approaches in combination of Woo's Approach and a large change of heading were presented for the practical shiphandlers, 2) According to simulation of the pilotship the angle of a large change of heading for reducing headway is more than 70 degrees approximately. 3) Applied this optimal approaches to the SBM operations of simulated Port of Ulsan and confirmed the control of ship and the economy of port approaches time.
