The solution of the environment problem is the common issue all over the world, for this reason the necessity of the environmental education of school has emphasized. On this a variety method for environmental education is needed, this paper planned and applied the 'ecology & environment' for high school which are based on GBS theory and presented a new model of environment education. GBS(Goal-Based Scenario) is that learners are presented with an end goal that is motivating and challenging. This goal is structured such that, in order to successfully meet it learners are required to build a predetermined core set of skills and knowledge by process mission and scenario. GBS is an active learning environment in which learners are trained in study that have a real-world context. When they are back in real-world they have increased ability to apply what was learned by reflecting on the GBS learning experience. This study was designed on GBS theory and taught a class by using internet Blog. As a result, when carefully reviewing the materials such as final presentation reflect journal, we conclude that the students' awareness of a learning environment is improved and the students seems to try to apply the learning outcome to a real life.

The infinite layer compound $ACuO_2$, (A-Alkaline earth) consists of infinite stacking of $CuO_2$ planes separated only by alkaline earth ions. This compound attracted much attention because it contains only key ingredient of all cuprate high temperature superconductor; $CuO_2$ plane with controllable carrier concentration without charge reservoir block. High pressure synthesis method has been found to be preferable for this system due to its ability of doping various lanthanide ion into A site with larger superconducting volume fraction. But rigorous study on this rudimentary compound has been hindered by insufficient quality of sample. Especially superconductlng volume fraction was often too small to identify its origin. In this presentation, we report high pressure synthesis of $Sr_{0.9}Ln_{0.1}CuO_2$ (Ln=La, Sm). By controlling the heating temperature precisely during high pressure synthesis we could have superconductors with quite high superconducting volume fraction for this compound. The magnetic properties of the graln aligned samples show very different behavior compared to the cuprate high temperature superconductors. Details will be discussed.

In this paper, we surveyed from students and professors of Hanbat National University to examine the current state of running the introductory engineering design and to derive the direction of future improvements of the subject. A total of 783 students from nine departments and 12 professors who are in charge of the introductory engineering design participated in the present questionnaire evaluation. Outcome categories of the interest in their major and the learning of design theory appears relatively lower than other learning outcomes of the introductory engineering design course. Accordingly, it is determined that the theoretical aspects of designing should be emphasized in performing a team project. The design process, writing and presentation ability, teamwork theory are dealt in more than 70% of the departments, but engineering ethics, patent, visualization education had not been addressed in a number of departments due to their department characteristics. While a lesson outcome of the creativity resulted in the largest for the students, most of the professor feel difficult in increasing the creativity. It is urgent to develope of teaching methods in order to promote the creativity in the introductory engineering design course.

지금까지의 독서교육은 교수-학습 활동과 연계되지 못한 채 별개의 것으로 인식되어 왔으며, 독서의 본질적인 측면보다는 독서자료의 제공이나 책을 다 읽고 난 후의 표현 활동에 치중하여 왔다는 문제점이 있다. 이에 본고에서는 교과학습과 독서 활동을 연계하고, 독서자료의 접근은 물론 실제 책을 읽는 인지적 활동 그리고 책을 읽고 난 다음의 표현 활동을 종합적으로 수행할 수 있는 웹 기반 독서교육 시스템을 설계, 제안하였다. 북어드벤처, 썬링크등 기존의 독서교육 시스템을 분석하여 웹 기반독서교육시스템의 요구사항을 도출하고, 이를 바탕으로 시스템을 설계, 제안하였다. 제안한 웹 기반의 독서교육시스템은 독서안내, 나의 독서수준, 책 고르기, 독서 전략, 독서표현, 독서토론 등 6개의 메뉴로 구성되어 있다.

Recombinant Escherichia coli displaying organophosphorus hydrolase (OPH) was used to overcome the diffusion barrier limitation of organophosphorus pesticides. A new anchor system derived from the N-terminal domain of ice-nucleation protein from Pseudomonas syringae InaV (InaV-N) was used to display OPH onto the surface. The designed sequence was cloned in the vector pET-28a(+) and then was expressed in E. coli. Tracing of the expression location of the recombinant protein using SDS-PAGE showed the presentation of OPH by InaV-N on the outer membrane, and the ability of recombinant E. coli to utilize diazinon as the sole source of energy, without growth inhibition, indicated its significant activity. The location of OPH was detected by comparing the activity of the outer membrane fraction with the inner membrane and cytoplasm fractions. Studies revealed that recombinant E. coli can degrade 50% of 2 mM chlorpyrifos in 2 min. It can be concluded that InaV-N can be used efficiently to display foreign functional protein, and these results highlight the high potential of an engineered bacterium to be used in bioremediation of pesticide-contaminated sources in the environment.

인터넷 기술의 발달로 기존의 추천 알고리즘은 사용자나 항목의 심층적인 특성을 학습할 수 없기 때문에 본 논문은 이 문제를 해결하기 위해 AMITI(주의 메커니즘 및 개선된 TF-IDF)에 기반한 추천 알고리즘을 제안했다. CNN(Convolutional Neural Network)에 2중 주의 메커니즘을 도입함으로써 CNN의 특징 추출 능력이 향상되고, 항목 특징에 다른 선호도 가중치가 할당되며, 사용자 선호도와 더 일치하는 권고사항이 달성되었다. 대상 사용자에게 항목을 추천할 때 점수 데이터와 항목 유형 데이터를 TF-IDF와 결합하여 권장 결과의 그룹화를 완료하였다. 본 논문에서 진행한 MovieLens-1M 데이터 세트에 대한 실험 결과는, AMITI 알고리즘이 권장 사항의 정확도를 향상시키고 프레젠테이션 방법의 순서와 선택성을 향상시킨다는 것을 보여준다.
