High-rising buildings are a sort of solution to recent cities. Till now real estate development was concentrated in new development on vacant lots, and it resulted urban sprawl. Generally large cities are confronted with the exodus of industry and population from city. High-rising buildings solve many problems associated with this problem. The purpose of this research is to identify the effect of super high-rise mixed use building project process on apartment price. For this study, the hypothesis is that price of apartments is influenced by project process of super high-rise mixed use building. The study concerned 4 variations of project process that is building permits stage, sale stage, construction starting stage and stage of moving into building. The target projects of buildings are selected by number of floor(over 40 floors) and construction time. And 48 apartment complex are selected around super high-rise mixed use building. This study uses hedonic price function to analysis effect of project process of super high-rise mixed use building. A price of apartments is defined as a dependent variable. Characteristics of residence, complex, district and super high-rise building are defined as independent variables. The results are as follows; first, there is no error in price model of this study. Second, it is found that apartment price was influenced negatively by building permit stage and sale stage of super high-rise mixed use building. But that was influenced positively by construction starting stage and stage of moving into building of that. Third, as the project process of super high-rise mixed use building was proceeded, price of apartments was increased.

Modal Shift from road to rail has been adapted in several countries as one of effective ways of reducing $CO_2$ emissions caused by transport. Generally, effect analysis of $CO_2$ reduction toward modal shift is calculated mainly from use stage and less consideration from other stages of life cycle, even though, in some case of modal shift needs that new line construction or new vehicle manufacturing. In this study, modal shift effect analysis is performed with considering construction, manufacturing vehicle and use stage. As a result we can get total $CO_2$ reduction effect using life cycle thinking and check the necessity of including other life cycle stage not only considering use stage. In conclusion, there is no $CO_2$ reduction effect if the reduction amount of $CO_2$ in use stage is not bigger than allocated annual amount of $CO_2$ in construction and manufacturing vehicle stage. According to this fact, analysing $CO_2$ reduction effect of Modal Shift should be considered not only the use stage.

This study was made on the concerns and implementation of the ICT(Inormation and Communication Technology)-utilized lesson by home economics teacher. The objective of this study is to investigate the stages of concern and the level of use of the ICT-utilized lesson by home economics teachers in Kyunggi Province through the concerns based adoption model(CBAM) and to provide assistance for ICT-utilizing lesson to be efficiently adopted to home economics. This study made selected 200 schools by random sampling among 233 middle schools which have two or more home economic teachers and 21 or more classes in Kyunggi Province which has a total of 395 middle schools and mail-surveyed on 400 home economics teachers by means of questionnaire. The stages of concern. the levels of use and the types of implementation were used as instruments in this survey. The results of this study on the stages of concern. the levels of use and the type of implementation of the ICT-utilized lesson by home economics teachers in Kyunggi Province were as following: First. the highest point of the concern of home economics teachers of ICT-utilized lesson was the stage of awareness. the second highest point was the stage of management. the 3rd stage. and the stage of information. the lst stage. Second. the highest level of implementation of ICT-utilized lesson by home economics teachers was the level of mechanical use. the 3rd stage(30.4％), which followed by the level of orientation. the 1st stage(22.5％). and the level of nonuse(16.7％). the level of rountine use. the 4th stage(13.7％) the level of integration. the 5th stage(11.8％). the level of preparation 2(3.9％). and the level of renewal. the 6th stage(1.0％) Third, information search was the most in the type of ICT-use and in the course of lesson CD-ROM was used the most.. During ICT-utilized lesson. most of teachers used computer one to two hours a week mainly in the lessons of clothing life and eating life. Home economics teachers took the most training of how to use word-processor(68.6％) during computer education. and 60 teachers(66.0％) gave positive response about the effect of computer education on teacher's learning. Finally. the biggest problem with ICT-use in the teacher's learning was the long preparation time for lesson. and problem with ICT-utilized lesson was the burden of time and effort spent to buy needed materials and to recompose the existing materials for the lesson. Therefore. so as to adopt ICT-utilized lesson efficiently into school it is needed that active promotion for the lesson should be made to teachers. training teachers to raise their ability to use computer and various kinds of software should be expanded. and school authorities' financial and administrative assistance should be given for the smooth proceeding of the lesson.

Simon's two-stage designs are frequently used in phase II single-arm trials for efficacy studies. A concern of safety studies is too many patients who experience an adverse event. We show that Simon's two-stage designs for efficacy studies can be similarly used to design a two-stage safety study by modifying some of the design parameters. Given the type I and II error rates and the proportion of adverse events experienced in the first stage cohort, we prescribe a procedure whether to terminate the trial or proceed with a stage 2 trial by recruiting additional patients. We study the relationship between a two-stage design with a safety endpoint and an efficacy endpoint as well as use simulation studies to ascertain their properties. We provide a real-life application and a free R package gen2stage to facilitate direct use of two-stage designs in a safety study.

World Business Council for Sustainable Development(WBCSD) is effort to achieve sustainable development in economic growth, environmental preservation and social development. Being this way, it is essential for developing evaluation tool which quantify to fulfill sustainable development. Eco-efficiency is one of the quantitative tools to evaluate environmental impact and economic aspect. Eco-efficiency, in general term, means creating more value of product or services with less impact to environment. It indicates as environmental impact in denominator and value of product or services in numerator. Eco-efficiency shows how much economic value reveals to unit environmental impact caused by product or service as an indicator. This study aims at developing eco-efficiency indicator of railway industry considering use stage among the entire life cycle stage of KTX and Saemaul train and also, figure out eco-efficiency value through indicator. Therethrough, it is enables to evaluate created value per environmental aspects. Since rail vehicles demands a lot of energy to transport people during use stage, the environmental impact is more significant than other lkfe cycle stages. Therefore, it quantified environmental indicator as CO2 emission and economic indicator as transportation record per a year with an annual income. This study contributes to be used as a tool for quantifying indicator of comparison evaluation in respect of rail vehicle in use stage.

Business managers are often required to use LP problems to deal with uncertainty inherent in decision making due to rapid changes in today＇s business environments. Uncertain parameters can be easily formulated in the two-stage stochastic LP problems. However, since solution methods are complex and time-consuming, a common approach has been to use modified formulations to provide upper and lower bounds on the two-stage stochastic LP problem. One approach is to use an expected value problem, which provides upper and lower bounds. Another approach is to use “walt-and-see” problem to provide upper and lower bounds. The objective of this paper is to propose a modified approach of “wait-and-see” problem to provide an upper bound and to compare the relative error of optimal value with various upper and lower bounds. A computing experiment is implemented to show the relative error of optimal value with various upper and lower bounds and computing times.

BIM is a practical and economical technology used in the construction process. Despite the fact that BIM is widely used in the design and another stage before construction, it is not largely applied during the construction stage itself. However, it is important to opt for BIM during construction stage because there may occur a number of risks such as construction delay and increased construction costs. Therefore, the present paper contains the analysis of the model use, which is mainly applied to respond to the BMI RFI that represents an information requirement of construction site workers, by analysing the BMI RFI application at the construction site. In addition, there is an analysis of the way the derived model use affects the project goal aimed at the project success.
