The environment is the important resource to use as well as to conserve for the development. Since 1990s, it has accentuated the importance of the environment and tried to conserve the environment in many areas. Among many area, the building industry has played a role to destruct the environment for providing the living decent space and brought the environmental affect. Therefore, the building industry should endeavor to mitigate the environmental affect. In building life cycle, it consumes the energy and natural resources. But it is difficult to evaluate the environmental affect during the whole building life. It is impossible to calculate the environmental affect without the much time and effort. Therefore. it requires the easy and handing program to calculate the affect to environment in each building life cycle. Until now, many program for assessing the affect to the environment have been developed and limitedly used because of the assessment scope and contents. In this paper, it aimed at developing the assessment program of LCA, focused on the energy consumption and carbon-dioxide emission compared with the domestic and foreign concerned programs. The developed program is divided into 3 areas; construction, maintenance, demolition.

As the importance of technology increases, so too does its use in various areas. In education, technology is often used. However, due to teachers' lack of knowledge about technology, they often remain at the level of simple utilization, without applying it to learning. Thus, there is a growing need for Technological Pedagogical Content Knowledge (TPACK), which enables teachers to have knowledge about technology and use it appropriately given the content. Although TPACK studies are underway in many subjects, they suffer from the limited functionality of the included technology. To solve this problem, in this study, the range of technology in TPACK was extended to programming, and a TPACK-P model was developed to teach this expanded TPACK to pre-service teachers. To verify the effectiveness of this model, the TPACK-P training program developed during the 15th classes was applied to 19 pre-service teachers. We used Park and Kang (2014) as a tool to measure these teachers' TPACK before and after treatment to observe any changes. The results showed that the TPACK-P education program showed statistically significant improvement in all areas except Pedagogical Content Knowledge(PCK). Compared with the ICT-based TPACK training program, which was administered to a control group, the TPACK-P training program proved to be more effective in the development of Technological Pedagogical Knowledge(TPK) and TPACK among pre-service teachers.

Recent, more and more steel deck bridges are adopted for the design of long span bridges and the upgrading of existing concrete deck bridges, mainly because of reduced self weight, higher stiffness and efficient erection compared to concrete decks. The main objective of this study is to propose on formulation of the design optimizations to develop an optimal desist program required for optimum desist for orthotropic steel-deck bridges. The objective function of the optimization is formulated as a minimum initial cost design problem. The behavior and design constraints are formulated based on the ASD and LRFD criteria of the Korean Bridge Design Code(1996). The optimum design program developed in this study consists of two steps. In the first step the system optimization of the steel box girder bridges is carried out. And in the second step the program provided the optimum design of the orthotropic steel-deck with close ribs. In the optimal design program the analysis module for the deck optimization is based on the Pelican Esslinger method. The optimizer module of the program utilizes the ADS(Automated Desist Synthesis) routines using the optimization techniques fuor constrained optimization. From the results of real application examples, The cost effectiveness of optimum orthotropic steel-deck bridges designs based on both ASD and LRFD methods is investigated by comparing the results with those of conventional designs, and it may be concluded that the design developed in this study seems efficient and robust for the optimization of orthotropic steel-deck bridges

In this study, an in-house program to analyze the performance degradation for gas turbines is developed using MATLAB and is validated using commercial software. This program consists of design and off-design calculations. The results of design calculation is used for reference values of off-design calculation. The off-design calculation is composed of measured and expected performance analyses, and turbine inlet temperature correction. In general, performance degradation is analyzed by comparing the results of measured and expected performance analysis. However, if gas turbine performance degrades, turbine inlet temperature might increase due to the general control logic to comply with the power demand. Therefore, it is required to consider the deviation of turbine inlet temperature from the normal value in the performance diagnosis to analyze the performance degradation exactly. In this study, a special effort is given to the correction of turbine inlet temperature. The accuracy of the developed program is confirmed by comparison with commercial software, and its capability of performance diagnosis using the turbine inlet temperature correction is demonstrated.

In this study, research results on organic and inorganic pollutant migration through single and composite liner were summarized. On the basis of these summarized research results, a design program for landfill liner, which can be used to optimize the liner thickness based on the allowable ground water criteria around the landfill subsurface, was developed. A reasonable liner thickness was obtained from the program output results, in the case of the migration of $Cl^-$ ion through a single clay liner. Therefore, the developed program could be used to carry out a preliminary design for landfill liners with respect to organic and inorganic pollutants.

Purpose: The purpose of this study was to develop a first aid coaching program (FACP) and to investigate its effects on the first aid knowledge, confidence, and performance of childcare teachers. Methods: A Delphi survey that included 16 experts was used to develop the FACP. A total of 60 participants were included to test the effectiveness of the program. The FACP developed using the survey results focused on improving first aid knowledge, confidence, and performance using a coaching-based method. First aid and cardiopulmonary resuscitation (CPR) performance was assessed using 39 items from the program content. Results: Using a 3-round Delphi survey, 6 areas and 42 detailed topics for group and individual coaching programs were developed. The knowledge scores were significantly higher in the experimental group than in the control group (t=4.24, p=.001). The confidence scores were significantly higher in the experimental group than in the control group (F=3.89, p<.001). The performance scores were significantly higher in the experimental group than in the control group (t=12.40, p<.001). Conclusion: Continuous application of the FACP among child care teachers is expected to minimize the harm caused by minor accidents at child care facilities. This program should be formally implemented on a consistent basis.

Purpose: The purpose of this study was to develop a health education program on the health promoting behavior and self-efficacy in university students and evaluate its effects. Method: A nonequivalent control group pretest-posttest design was used. The subjects were 148 students [experimental(N=80) and control(N=68) groups] from a university in J City. The experimental group members participated in thirteen sessions of a health education program for fifteen weeks and the degree of their health promoting behavior and self efficacy was evaluated. The instruments for this study were the health promoting lifestyle profile developed by Walker et al.(1987) and self-efficacy scale developed by Sherer & Maddux(1982). Data were analyzed by descriptive statistics, Chi-square tests, t-tests, and paired t-test using SPSS 10.0. Result: The experimental group had a significantly higher health promoting behavior score(F=10.389, p=.002) than the control group, while no significant difference was found in the self-efficacy score(F=.481. p=.489). Conclusion: The results suggest that the health education program can be utilized as an effective program to promote health promoting behavior in university students.
