We have developed inventory database program which is available in the mobile PC. The mobile PC is convenient in terms of portability, data input, modification, practicality of various program and data confirmation in site. By utilizing the inventory database program in mobile PC, we are able to complete database in site. Then, database is converted into the Hangul document and Excel worksheet. Also, based on the above procedure, effective management and utilization of inventory on cut-slope can be achieved.

A number of methods based on various ideas have been proposed for simulating the non-Gaussian stationary process. However, these methods have some limitations. This paper reviewed several simulation methods based on the translation method using logarithmic and polynomial functions, which have emerged in the history of statistics and in the field of civil engineering. The applicability of each method is discussed from the viewpoint of the reproducibility of higher order statistics of the object function in the simulated sample functions, and examined using pressure signals measured from wind tunnel experiments for various shapes of buildings. The parameter estimation methods, i.e. the method of moments and quantile plot, are also reviewed, and the useful aspects of each method are discussed. Additionally, a simple worksheet for parameter estimation is derived based on the method of moment for practical application, and the accuracy is discussed comparing with a set of previously proposed formulae.

조명시스템의 경제성에 크게 영향을 주는 요소들을 보면 초기 설비비, 보수비, 전기요금 등이 있다. 이 중에서 보수비는 램프 교환비, 램프교환 인건비, 청소비로 구성되어 있으므로 보수계획에 따라서 조명시스템의 경제성이 다르게 나타난다. 따라서 설계초기에 어떠한 조명시스템이 경제적으로 유리한가를 예측하는 것은 중요하다. 그러므로 본 연구에서는 국내에서 평균조도를 계산하는데 사용되는 ZCM에서의 보수율 구성 요소들을 변화시켜 보수율 값을 산정한 후 조명시스템의 경제성 평가 위해 개발한 WEELS(Worksheet for Economics Evaluation of Lighting Systems)에 적용하여 조명시스템에서 보수율의 중요성을 보였다.

Since 1980, rapid social and economic development due to increased plant construction has led to a plant dormitory in a short period. In recent years, by the advent of the durability of dormitory remodeling is a critical need. However, user requirements due to the lack of owner's budget do not reflected. As a result, users have complained about the scope of construction, and construction stakeholder in accordance with the budget efficiency of the complaints have decreased. In this study the remodeling requirements in the planning stages is proposed for the remodeling process. In addition work type and element can select a range of construction worksheet are proposal.

This paper reports on the learning journeys in mathematical problem solving of 21 teachers enrolled on a Masters of Education course entitled Discrete Mathematics and Problem Solving. It draws from the reports written by these teachers on their personal journeys: the commonalities and differences among them in terms of how they look at their own problem solving experiences, what language they employ in talking about problem solving, and what impact the course has on their views about problem solving. One particular aspect of problem solving instruction, a pedagogical innovation called the Practical Worksheet, is addressed in some detail. These graduate students are full-time mathematics teachers with at least two years of classroom experience. They include primary and secondary teachers.

The purpose of this study is to examine the effects of creative thinking activities and scientific attitude through the use of storytelling in the STEAM program for elementary students. For the purpose of this study, a teaching plan and worksheet for students using storytelling in STEAM was developed and applied. The results of this study are as follows: First, the change in students' creative thinking activities by applying the STEAM program using storytelling has statistically meaningful difference (p<.05). Second, the improvement in the scientific attitude score has statistically meaningful difference(p<.05). Third, according to the analysis of a questionnaire used to evaluate the program, students had a positive perception of the STEAM program and gained higher level of satisfaction about the lesson. Therefore, using storytelling STEAM program applied in this study might be useful to improve creative thinking activities, and can be expected to improve scientific attitude and should be widely applied to gifted education.

The purpose of this study is to examine the effects of interest in science and STEAM Literacy through the use of the design based STEAM program utilizing Smart Device for elementary students. For the purpose of this study, a teaching plan and worksheet for students using STEAM Programs was developed and applied. The results of this study are as follows: First, the improvement in the interest in science score has statistically meaningful difference(p<.05). Second, the change in students^{\backprime} STEAM Literacy by applying the design based STEAM program utilizing Smart Device has statistically meaningful difference (p<.05). Third, according to the analysis of a questionnaire used to evaluate the program, students had a positive perception of the STEAM program and gained higher level of satisfaction about the lesson. Therefore, design based STEAM Program utilizing Smart Device applied in this study might be useful to improve STEAM Literacy, and can be expected to improve interest in science and should be widely applied to Science education.

The purpose of this study was to examine the effects of the creative problem solving and scientific attitude through the science-based STEAM program for the elementary gifted students. For the purpose of this study, a teaching plan and worksheet for students based on STEAM was developed and applied. The objects of this study were the fourth grade of both an experimental class (18 students) and a comparative class (20 students) at the gifted class located in Gyeonggi Province. The results of this study were as follows: First, the change in students' science creative problem solving in the experimental group applying science-based STEAM program has statistically meaningful difference (p<.05). Second, the scientific attitude score of the experimental class improved, but it has no meaningful difference statistically. Third, according to the analysis of questionnaire for evaluating the program, experimental class students had a positive recognition in respect of the STEAM program and got higher satisfaction about the lesson. Therefore, science-based STEAM program applied in this study might be useful to improve the creative problem solving, and can be expected the scientific attitude' improving and better be widely applied to gifted education.

A study on ventilation design using the spreadsheet model is carried out to propose means of available design. A sample of complex ventilation system In the non-standard condition Is used to illustrate thins spreadsheet model. In developing the spreadsheet model, this study has attempted to it general by using computional equations and design parameters that can be readily applied to any spreadsheet software. Also, most design data is contained in the spreadsheet template. This template provides the same design information as the ACGIH worksheet, and operates Quickly and emclenuy, and is fiexible enough to use under different conditions. This spreadsheet model allows the ventilation engineer to design quickly and accurately the ventilation system, without spending too much effort In the design process. By storing on computer and diskette, the design data computed finally can be used as a permanent record of specific ventilation system, and because of finally to be able to design over and over again while making only slight changes to the Input data, the spreadsheet model is used availably to accomplish the design optimazation by redesign and troubleshooting by review from field measurements. Also, the spreadsheet model is available for designing ventilation system under different condition or evaluating existing system or design drawing, because changes In the layout or formulae can be readily made to fit the needs of the designer.
