This paper presents the application of a neural network for prediction of the unconfined compressive strength from physical properties and schmidt hardness number on rock samples. To investigate the suitability of this approach, the results of analysis using a neural network are compared to predictions obtained by statistical relations. The data sets containing 55 rock sample records which are composed of sandstone and shale were assembled in Daegu area. They were used to learn the neural network model with the back-propagation teaming algorithm. The rock characteristics as the teaming input of the neural network are: schmidt hardness number, specific gravity, absorption, porosity, p-wave velocity and S-wave velocity, while the corresponding unconfined compressive strength value functions as the teaming output of the neural network. A data set containing 45 test results was used to train the networks with the back-propagation teaming algorithm. Another data set of 10 test results was used to validate the generalization and prediction capabilities of the neural network.

The purpose of this study is to understand and compare the characteristics of the content organization system of three Environment textbooks currently used, and to examine its connectivity with the teaching & teaming methods included in the Environment subject part of the 7th Korean National Curriculum. For the analysis three Environment textbooks for middle school and their teacher's guide books by three companies. published(A, B, and C) The result of the taxonomic analysis showed that three Environment books had different steps to get to the lesson class unit in the way that A of six steps, B of five steps and C of seven steps. The amount of main text was different In the domains of'Human and Environment','Environmental Problems and its Counter-plan'and'Environmental Conservation'of three textbooks each. All of three textbooks had the biggest percentage in sub-domains of'Living Environment to Keep'and'Global Environmental Problem'in 'Environmental Problems and its Counter-plan'domain. Considering teaching & loaming methods all of three textbooks contained many activities as 55 in A, 66 in H and 91 in C. Among 9 teaching 8E teaming methods and others listed in the Environment subject part of the 7th Korean National Curriculum, the investigation method is most frequently used in all of three textbooks. The drama, the paly and the case study were used rarely as teaching & teaming methods in activities In the consideration of the content amount regarding academic fields, it was revealed that three textbooks overemphasized the aspect of natural sciences comparing the aspect of human & social sciences aspect as a whole. Generally the appendix section of all three textbooks were well organized to support the teaching and teaming activities in main text.

In this paper we present Logical Evolution method which is a new teaming algorithm for the concepts expressed as binary logic function. We try to solve some problems of Inductive Learning algorithms through Logical Evolution. First, to be less affected from limited prior knowledge, it generates features using the gained informations during learning process and learns the concepts with these features. Second, the teaming is done using not the whole example set but the individual example, so even if new problem or new input-output variables are given, it can use the previously generated features. In some cases these old features can make the teaming process more efficient. Logical Evolution method consists of 5 operations which are selected and performed by the logical evaluation procedure for feature generation and learning process. To evaluate the performance of the present algorithm, we make experiments on MONK data set and a newly defined problem.

This paper proposes an adaptive tutoring system that provides learning materials dynamically according to the learners' teaming character and ability. Our system, in which a learning phase and a test phase are linked together, supports the personalized instruction-learning by providing the teaming materials by level in the learning phase according to the teaming ability estimated in the test phase. We design and implement a tutoring system consisted of an evaluation component and a learning component. An evaluation component uses a computerized adaptive test(CAT) based on item response theory to evaluate learners' ability while a learning component employs fuzzy level set theory so that teaming contents are provided to learners according to learners' level.

UAV-UGV teaming concept has been proposed that can compensate for weak points of each platform by providing carrying, launching, recovery and recharging capability for the VTOL-UAV through the host UGV. The teaming concept can expand the observation envelop of the UGV and extend the operational capability of the UAV through mechanical combination of each system. The spherical-shaped coaxial rotorcraft UAV is suggested to provide flexible and precise interface between two systems. Hybrid navigation solution that included vision-based target tracking method for precision landing is investigated and its experimental study is performed. Feasibility study on length-variable rotor to provide the compact configuration of the loaded rotorcraft platform is also described.

This study suggests that the contents and methods focusing on the leamer's geographical experience of everyday life and environments, are very effective for teaching and teaming in geography subject matter. The contents have to be selected and structurized from private geographies about their region of everyday life for teaming abstractive and scientific concepts of geography. Scientific concepts of geography, i.e. geographical concepts become 'scope'for selecting the contents and these systematic structure substitutes 'sequence'. The criteria by which selected contents of teaching and teaming based on everyday life may consist of three elements: region as leamer's place for everyday life; concrete experience of the place; and leamer's changing geographical experiences.

This study aims to examine the 5th grade students' motivation and the influence of the movivation on their science learning with ARCS strategies. To achieve the goal of the study, two groups were selected from an elementary school at Changwon, in Korea: Treatment Group (TG) and Control Group (CG). TG was trained for applying ARCS strategies, whereas CG were taught in a traditional manner for 13 weeks. Before and after the treatment, both groups answered the questions in the form of PALS in order to know their general motivation of teaming science. In the middle of the treatment, they were also tested to sort out their motivation, which might be occurred during the class, by CIS. After the period of the 13 weeks, the students' motivation were finally measured after their teaming with ARCS strategies. The results are as follows: First, there were significant differences between TG and Cf when motivation was measured by PALS. Second, there was also significant contrast between TG and CG in CIS, which was conducted during the class. TG gained more scores on the ARCS motivation, attention, relevance, confidence, and satisfaction. Third, It has been found that most students recognized the ARCS as one of the positive and interesting teaming strategies. To conclude, the results above show that the ARCS strategies would be very helpful for the 5th grade students to improve their teaming motivation as well as to appeal their interest on their science loaming.
