This study aims to analyze the image of long-span structures. For the intention, it analyzes the relationship between images and physical attributions of elements such as materials, stresses, configurations, compositions and shapes of structures. The image of structures can represent following 5 factors; friendly-unfriendly, strong-weak, dynamic-calm, superior-inferior, and regular-irregular. The friendly-unfriendly in the image of structure mostly determines on a finished material and partly with a structural shape. The strong-weak in the image of structure determines on configuration of the structural members. The dynamic-calm in the image of structure determines on the structural shape. Hence the structure has dynamic forms when it seems to be open and sharp, namely when it receives the flow of forces in the structural shape, and it has a (-) gauss curved rate or an diagonal appearance. The superior-inferior in the image of structure determines on composition of structural elements. The structure seems to be superior is contributed not simply to support load but positively to create design as a tectonic element. From now on, this study can provide the useful information on the long-span structure design through the more appropriate analysis of the image.

The current study aims to examine differences of mother's child-rearing attitude by background variables of infant's and mothers, the influence of mother's child-rearing attitude, temperament and goodness of fit of infant's on adjustment to childcare center, and relative influence among elements. Subjects for the study were 165 infant's of two year old attending 8 childcare centers in Seoul, Gyeonggi-do and Jeju-do, and their mothers and homeroom teachers at childcare centers. As a result of the study, it was found that there was no difference in background variables such as sex and order among siblings of infant's, childcare experience and average hours at childcare centers a day, and mother's age and job, while there were differences in mother's child-rearing attitude by mother's education, household's monthly income and mother's working hours per week. Also it was observed that mother's restrictive attitude, positive attitude and infant's regular temperament influenced their adjustment to childcare centers, and relatively influential elements on general adjustment to childcare centers were mother's restrictive attitude and positive attitude. That IS, it was found that as mother's restrictive attitude and positive attitude were high, infant's general adjustment to childcare centers became high. These study results show that if infant's learn basic rules and habits from parents at home by having positive relationship with mothers, getting appropriate educative instruction, having proper autonomy and obtaining positive assessment from their mothers, rather than strict restriction or bluff, can adapt themselves to childcare centers with no difficulty.

The Ministry of Education issues STEAM education as a part of convergence. Most important is "How to achieve goals of STEAM education". The goal of this paper searches possibilities that robot is a good tool for STEAM education. The main topic is photosynthesis unit as circumstantiation and "Deep sea exploration robot", is creative activity, in elementary science subject. Students complete 13 basic course about robot, then accomplish subject-oriented 10 robot application course about above topic. Basic course contains math and science elements that students learn in regular curriculum. Application course is organized following steps, photosynthesis with oxygen sensors, brainstorming, idea derivation, robot design, robot construction, demo and presentation and so on. These courses have elements of STEAM. Finally teacher has face-to-face meeting with parents and students. Most have positive aspects about this process in terms of creativity, study attitude, and school life. Specially low-ranking students win a prize in robot competition. So they can gain confidence and accomplishment. This paper don't show statistic chart, but we surely knew that robot education for STEAM education seriously affect creativity huminity and job search.

In this study, in order to facilitate analysis in a continuous sequence, including the concept of the landscape experience time, countless frames of a continuous landscape were extracted. The amount of visual elements in each frame was data-converted numerically to take advantage of the quantitative data necessary for landscape planning and design was calculated in the rhythm of the sequence. In Order to shoot video with the flow of the line of sight of experience in landscape districts and landscape control points along the landscape corridor which is a continuous path, each of the corresponding computer motion techniques. This study developed a CRVP Koo computer program to effectively calculate the continuous visual number of specific landscape components by extracting uncounted frames at regular intervals, and after verifying, attempting to apply this to the target site. Through the applied result, it was possible to extract the digitized quantitative rhythm for each component of each landscape, the margin of error is very small when compared with the results of manual in photoshop, it was able to overcome the drawbacks of the manual. Using the rhythm of the derived sequence, and those close to the experience of the landscape, it was possible to achieve quantitative analysis derived from a variety of perspectives as well as was possible to be used as quantitative basis data and analysis technique for landscape planning and design.

This study focuses on the raw material characteristics, including firing temperature and the similarity of clay body, and making techniques on the underwater ceramics from offshore of Taean Mado, the Republic of Korea. The ceramic specimens include various types of celadons, Buncheongwares and white porcelains with very similar physical characteristics. All the clay bodies composed of same mineral phases within mullite and quartz, while cristobalite were also found in some white porcelains. Also, the geochemical composition of the clay body shows regular behavior properties for all the elements consisting of the celadons and Buncheongwares. In contrast, the irregular properties of trace and incompatible elements were found in white porcelains. Therefore, it is presumed that the white porcelains were made using the clay body with different source from the celadons and Buncheongwares. Notably, some white porcelains in low Th content are assumed to be made with clay formed in a different environments. Meanwhile, most of the ceramics had gone through the firing of 1,200 to 1,300℃, with some celadons fired from 1,150℃ to 1,200℃. Also, it can be interpreted as some white porcelains were fired on even up to 1,500℃.

The purpose of this study is to analyze the organization of trading area and fashion trend in Gumi based on the observation of fashion brand stores which had been undertaken on a regular basis from July 2001 through July 2004. Gumi has over 1,000 stores located in main trading streets, about $25\%$ of which was fashion retail stores. In July 2004, $64.6\%$ of them was selling branded products, and the number of unisex casual wear stores was the greatest, followed by women's casual wear stores, sportswear stores, and children's wear stores. On the main streets of Gumi, casual attires as well as casual wear stores can be easily observed because the population of eumi is young compared to that of other regions. Among casual wear brands, especially sensory, or trendy casual wear brands such like BNX, A6, Coax, Koolhaas, EXR, and Smex came into Gumi area in large numbers since fall of 2002. From the observation data, dynamic and systemic effects of economic state, population, seasonal elements, product characteristics, etc. on the organizations of trading area were identified.

Most data parallel languages provide the block-cyclic distribution (cyclic(k)) that is one of the most general regular distributions. In order to generate local addresses for an array section A(l:h:s) with block-cyclic distribution, efficient compiling methods or run-time methods are required. In this paper, two local address generation methods for the block-cyclic distribution are presented. One is a simple scan method that is modified from the virtual-block scheme. The other is a linear-time ${\Delta}M$ table that contains the local memory access information construction method. This method is simpler than other algorithms for generating a ${\Delta}M$ table. Experimental results show that a simple that a simple scan method has poor performance but a linear-time ${\Delta}M$ table generation method is faster than other algorithms in ${\Delta}M$ table generation time and access time for 10,000 array elements.

The purpose of this study is to introduce the science-play in the regular class, stimulate the student's curiosity, motivate them and take active part in their science class. To make an effective science class, we developed the science-play activity instead of experiments in the text, and applied it to the class. The experimental group has statistically meaningful results in the science process skills, expecially in subordinate elements such as observation, deduction, expectation, data analysis and assumption establishments(p<.01). However, the comparative group has no meaningful results in the science process skills. Though the average value of the science related attitude in the experimental group had only a little increase and had no statistically meaningful results, that in the comparative group has decreased during the same period. As for the experimental group, the science-play activities were repeated and their science related attitude has increased a little. Even though there were no meaningful statistic results(p>.05), the science-play activity was effective in the science related attitude. As a result of this research, it could be said that the science-play activity can improve the student's science process skills and the science related attitude, and the science-play program should be further developed and applied to make easy and effective science classes.

The effective length method for flexural (column) buckling has been used for many decades but its use is somewhat limited in various contemporary design codes to moderately slender structures with elastic critical load factor (${\lambda}_{cr}$) less than 3 to 5. In pace with the use of higher grade steel in recent years, the influence of buckling in axial buckling resistance of a column becomes more important and the over-simplified assumption of effective length factor can lead to an unsafe, an uneconomical or a both unsafe and uneconomical solution when some members are over-designed while key elements are under-designed. Effective length should not normally be taken as the distance between nodes multiplied by an arbitrary factor like 0.85, 1.0, 2.0 etc. Further, the classification of non-sway and sway-sensitive frames makes the conventional design procedure tedious to use and, more importantly, limited to simple regular frames. This paper describes the practical use of second-order analysis with section capacity check allowing for $P-{\delta}$ and $P-{\Delta}$ effects together with member and system imperfections. Most commercial software considers only the $P-{\Delta}$ effect, but not member and frame imperfections nor $P-{\delta}$ effect, and engineers must be very careful in their uses. A verification problem is also given for validation of software for this type of powerful second-order analysis and design. It is a trend for popular and advanced national design codes in using the second-order analysis as a norm for analysis and design of steel structures while linear analysis may only be used in very simple structures.

Recently, not only development of curriculum associated directly with job, the development of new education model is in great need. So, the purpose of this study is to develop the instructional design guideline utilizing goal-based scenario(GBS) for college students who major in culinary arts. First, to achieve this goal, we recognized the 7 core elements(learning goal, mission, cover story, role activity, scenario operating, resource, feedback) composing GBS through literature review and case study. Second, we drew a conclusion about the problem and guideline for traditional culinary practice course by conducting inspection about culinary practice environment and needs with professors who are teaching culinary arts. Third, we applied the instructional design guideline for culinary practice to regular classes according to GBS's factors, and then we did formative evaluation with content experts and educational technology expert. Finally, we designed the final instructional design guideline for culinary practice by modifying early model reflected the result of formative evaluation. The results of this study are as following. First, when we applied GBS to culinary practice, professors have to focus on process of materialization by developing easy scenario to students. Also, they have to prepare the class circumstance to feel about sense of realism in advance. Second, to give a conjugally new skill at working, professors's effort is important. culinary practice education at college has responsibility to carry out the vocational training that has competitiveness and difference with labor market's needs. Therefore, it is necessary for us to develop the teaching and learning model for culinary practice which is suitable for major based on the manpower demand for industry without causing job mismatch from demand for industry.
