The conceptual structural design consists of selecting structural material and form of the building, producing a preliminary dimensional layout. The information such as height of the building use, typical live load, wind velocity, design acceleration, maximum lateral deflection, span, story height is a important factor in conceptual design phase. In this case, the knowledge solutions for past similar problems cam be used in the process of defining and finding a solution to the design problems. In this paper, the conceptual structural design method using case-based reasoning which is intended to assist engineers in the conceptual phase of the structural design of tall buildings is introduced. Inductive retrieval method and nearest-neighbor retrieval method are used for selecting structural system and similar design case, respectively.

The Magnet Methodology is not the recording of knowledge, skills, techniques, and other information from the past, but creating a knowledge base using present issues of problems for students' and teachers' life-span development through the exploration of career choices and development. In short, it is the multi-cooperative information system for commensalism. It is the magnet program that connects various level of educational institutions under a certain theme and enables students to choose on their own. And this magnet program is being adminstered by the magnet school. And some regular schools provide magnet program as vocational educations and extra-curricular activities. Magnet program reflects the concept of desegregation which was proposed by the U.S. Federal Court decision against the racial conflict which had culminated in the 60s and 70s. Magnet program enables students to choose their own programs and schools, and gives teachers and students the opportunities to develop their teaching method and learning method. That's why magnet program is called continuous, future-oriented one. Teachers and students can also get fair judgement on their activities due to the voluntary magnet program. It mainly deals with practical issues, so it is very realistic to establish the multi cooperative information system including companies, homes, communities, or governments under these practical issues. The openness of magnet program is guaranteed not only by the characteristics of the program but also by the physical layout of the magnet schools. There are no doors and walls, and classrooms are facing one another and sharing all the opinions and information. This precisely corresponds to the concept of co-existence of eco-system and the interdisciplinary approach which is essential to solve our problems.

Genetic Programming (GP) is an intelligence technique whereby computer programs are encoded as a set of genes which are evolved utilizing a Genetic Algorithm (GA). In other words, the GP employs novel optimization techniques to modify computer programs; imitating the way humans develop programs by progressively re-writing them for solving problems automatically. Trial programs are frequently altered in the search for obtaining superior solutions due to the base is GA. These are evolutionary search techniques inspired by biological evolution such as mutation, reproduction, natural selection, recombination, and survival of the fittest. The power of GAs is being represented by an advancing range of applications; vector processing, quantum computing, VLSI circuit layout, and so on. But one of the most significant uses of GAs is the automatic generation of programs. Technically, the GP solves problems automatically without having to tell the computer specifically how to process it. To meet this requirement, the GP utilizes GAs to a "population" of trial programs, traditionally encoded in memory as tree-structures. Trial programs are estimated using a "fitness function" and the suited solutions picked for re-evaluation and modification such that this sequence is replicated until a "correct" program is generated. GP has represented its power by modifying a simple program for categorizing news stories, executing optical character recognition, medical signal filters, and for target identification, etc. This paper reviews existing literature regarding the GPs and their applications in different scientific fields and aims to provide an easy understanding of various types of GPs for beginners.

In any large heavy industry like that of ship building, there exist a lot of complications for the arrangement of building blocks optimally for the minimal space consumption. The major problem arises at yard because of laxity in space for arranging the building blocks of ship under construction. A standardized erection sequence diagram is generally available to provide the prioritised erection sequence. This erection sequence diagram serves as the frame work. In order to make a timely erection of the blocks a post plan has to be developed so that the blocks lie in the nearest possible vicinity of the material handling devices while keeping the priority of erection. Therefore, the blocks are arranged in the pre-erection area. This kind of readiness of blocks leads to a very complex problem of space. This arises due to the least available space leading to an urgent need of an availability of intelligent spatial schedule without compromising the rate of production. There exists two critical problems ahead namely, the spatial occupation layout of pre-erection area and the emptying pattern in the spatial vicinity. The block shape is assumed be rectangular. The related input data's are the dates of erection (earliest as well as the latest), geometrical parameters of block available on pre-erection area, slack time and the like.

Recently, smart devices can be used with a variety of programs. Because of these characteristics, suitable lectures are provided to mobile device in Korea educational facilities. However, it is possible to reduce the learning efficiency from taking courses. because of many smart devices are using in a small display. Therefore, we need effectively in a small display content layout for overcome these problems. In this paper, we proposed content layer format for smart devices by Illustrated Programs based on Golden Ratio.

The manufacturing environment on which this research is focused is an FMS in which AGVs are used for material handling and each part type has one or more process plans. The research aims at developing a methodology whereby, given a part and volume mix for production during any production session, the best set of process plans including one plan per part type is selected and the best unidirectional AGV guidepath can be dynamically reconfigured in response to changes in parts and lot sizes combination. For the integrated PPS/FGD problem in which two functions of process plan selection (PPS) and flexible AGV guidepath design (FGD) are integrated, a zero-one integer programming model is developed. The integrated problem is decomposed into two subproblems, process plan selection given a directed AGV layout and AGV guidepath design with a fixed process plan per part type. A heuristic algorithm that alternately and iteratively solves these two subproblems is developed. The effectiveness of the heuristic algorithm is tested by solving various randomly generated sample problems and comparing the heuristic solutions with those obtained by an exact procedure. From the test results, the following conclusions are drawn: 1) For a reasonable size problem, the heuristic is very effective. 2) By integrating the two functions of PPS and FGD, a remarkable benefit in total production time for a given part and volume mix is gained.

First appeared in the 1970s, the underground shopping mall has been spreading across the country, and there reportedly exist 77 malls in the 2010. After over 30 decades operation, many underground shopping malls are now under the planning phase for renovation in many cities. This study considers the renovation issue of the underground shopping mall in the perspective of spatial re-configuration. A case is taken from Kangnam TerminalUnderground Shopping Mall in Seoul for detailed observation and suggestion. The monotonous and confusingspatial layout of the existing mall is investigated by observation methods. Based on the observation, a modifiedplan is suggested and evaluated by means of computer simulation program, Depth Map. The program mainly deals with visual network analysis in order to quantify the optical exposure in a given space. It is argued in this paper that the enhanced visual connectedness could affect the pedestrian performance positively in the shopping mall, and this leads to an easy and quick access to each shops in users' stand point. It is thought that this configurational solution for the remodelling of a specific case would be an effective reference for other malls in the country which are facing the similar problems.

The aim of this study is to find out problems between the '7th National Curriculum' and '2007 Revised National Curriculum' that would initially apply from 2009 and then to suggest better ways to improve computer education in Middle schools. A survey was carried out with a questionnaire. Based on the result, a comparison was made and a suggestion has been derived: Firstly, the computer subject should not be treated as a rival to others anymore, rather it should be considered as an essential subjects. Secondly, teachers who take computer subjects as their major should be allocated to middle schools. Thirdly, computer subjects should be taught systematically from elementary and be continued throughout in order to promote the level of the computer science education. Fourthly, the advantages of computer utilisation should be taken into account to layout the computer curriculum that is practicable and learner-centered. Finally, teachers should recognise the main aim of computer education and teach computer subjects to be useful in education. Though the revised version is not perfect the more the curriculums are revised, the better they might be expected to be developed. Consequently, whenever the newly revised computer curriculum emerges, the defects should be identified and addressed in order to achieve the aim of the computer curriculum.

In the modern society, magazine is a information communicating media which is an important element in assessing the whole of a nation's cultural standard. More subdivided fields of magazines are expanding according to the diversified concepts. As the variety of Korean edition of foreign magazines are increasing, the type of Women's magazines are also diversifying and expanding. By finding out the problems and analyzing the visual side of domestic women's magazines among the intense competition of the magazines, the design improvement program was requested. The analysis result from the visual side of domestic women's magazines tells us that the problem of current domestic women's magazines is that their identities are not clear. The cause can be divided into three reasons: First, it is the lack of creativity and originality. There is a limitation in arousing the readers' interests by designing the magazines with similar layouts. Second, there are no distinct design concepts in the magazines. It seems as if the uniformity is lacked as the impression the magazine gives is not clear. The diversification of layouts and the use of design elements could actually bring about a counter result. Third, the excessive advertisement pages is another reason. The ads that covers over 35% of the whole of the magazine can act as a factor that drops the readers' trust in the magazine.

In this paper, we implemented a looms management system which supports remote monitoring and scientific management of the looms. In the implemented system, the layout of the looms is placed in the user interface, and each loom's operating state and rate are automatically represented there. The implemented system has aggregate query processing functions for the looms existing in the selected area by the louse and it also has high level query processing functions to support the chart and pivot table; it can be used as a decision support system. The proposed system can detect temporal or persistent problems of the looms. Therefore, it can be used to raise the productivity and to reduce the cost in textile companies by coping with the situation properly.
