The purpose of this study was to analyze the characteristics of the pre-design of brownfield's by comparing LDA, EPA, and BRA of UK and USA in terms of establish mainbody, brownfield information, development process, opening development information. Such analysis will generate important implications for the development and renewal of brownfield in Korea by gaining insights into the characteristics of brownfield that reflect systematic and effective management and planning for urban renewal. The findings from this study indicate that: 1. Information on brownfield plays an important role at the development and planning stages that precede architectural design. 2. There is a great need for organizations that are responsible for brownfield renewal, such as LDA of UK, EPA and BRA of USA, in Korea, to make information public and to practice systematic management. 3. Discussion on the pre-design that follows contamination and renewal of brownfield and the developmental strategies that satisfy both the developmental and public profits are warranted.

In order to model a connection part between a control fin and actuator, the related characteristics of a dynamic stiffness were extracted from experiments. These characteristics include the static stiffness of a control fin and the dynamic stiffness of an actuator, so they are called the mixed dynamic stiffness here. This mixed dynamic stiffness is used as the boundary condition of a control fin connected to an actuator when the flutter characteristics are analyzed. The simulated stiffness of an actuator is corrected from the experiment results and the mixed dynamic is finally formulated in the domain of frequencies.

This study aims to compare human resource development by industrial and occupational characteristics of science and engineering graduates. To achieve research objectives, this study analyzed whether differences exist in human resource development, such as participation in vocational training, wage levels, and cuture of talened person preference, by industrial and occupational characteristics. The results showed that workers in engineering fields received more benefits and support compared to those in non-science and engineering field occupations at the quantitative statistics of vocational training and wage levels. On the contrary, according to the qualitative statistics, workers of non-science and engineering field have a culture of talented person preference compared to those in science and engineering occupation.

Failure occurred slope, due to typhoon 'Rusa' and 'Maemi' last two years, was studied to evaluate the slope failure characteristics. There're three types of the slope in this study, ie. soil slope, rock slope, mixed slope. Statistical analysis was used to estimate the relation between slope type and failure mode. Among the failure occurred slope, soil slope & mixed slope are dominant at the ratio of 33%, 44% respectively. We conclude that soil slope & mixed slope have more higher risk than rock slope during heavy rainfall.

This paper investigated sound characteristics by the delamination of an acoustic window. In detail, acoustic scattering and transmission characteristics on the delaminated acoustic window were estimated using an experimental and numerical approach. The experiment results showed that acoustic wave could lose its amplitude and take phase delay when it propagates the delaminated acoustic window. The numerical results showed that scattering phenomena occur on the delamination surface. The scattering characteristics presented differently according to the delamination size in the acoustic window. It also showed that transmitted sound distortion due to delamination could cause a direction detection error of SONAR by changing the position of the main lobe and the magnitude of the side lobe. In conclusion, the delamination has to be managed during the manufacturing process of acoustic windows.

Using samples of working mothers with 0-to-47 month old children extracted from the National Longitudinal Survey of Youth (NLSY), this study investigated effects of mothers' job characteristics on parenting behaviors and young children's motor, social, and cognitive development. Date were analyzed by descriptive statistics and multiple regression analysis. Results indicated that (1) job dissatisfaction was negatively related to children's development. (2) Working fewer hours was positively associated with mothers' cognitively stimulating parenting behaviors. (3) Total earnings were a positive predictor of mothers' emotional support. (4) The availability of a flexible hour benefit was positively related to mothers' cognitive stimulation level but the availability of a paid sick and vacation days combined benefit was negatively related to mothers' cognitively stimulating parenting behavior.

The Quality Function Deployment(QFD) is a Quality Management technique to maximize customers' satisfaction by reflecting customer requirements into all business processes, including concept definition, product planning, parts planning, process planning, production planning, and sales planning. The basic concept of the QFD is to translate customers' requirements appropriately into engineering characteristics, into parts characteristics, into process characteristics, and into specific requirements and activities in production. In this study, we reviewed and analyzed the application process of the QFD to the development of A2 FATC (Full Automatic Temperature Controller), an automotive component developed and produced by company A. It has been reported that by applying the QFD to the development of A2 FATC, company A. achieved 34% improvement in control robustness quality characteristic, 27% improvement in deviation quality characteristic, and 30% improvement in overall quality characteristics.

An Integrated Test Facility(ITF) is a human factors experimental environment to evaluate an advanced man machine interface(MMI) design. The ITF includes a human machine simulator(HMS) comprised of a nuclear power plant function simulator, man-machine interface, experiment control station for the experiment control and design, human behavioural data measurement system, and data analysis and experiment evaluation supporting system(DAEXESS). The most important features of ITF is to secure the flexibility and expandibility of Man Machine Interlace(MMI) design to change easily the environment of experiments to accomplish the experiment's objects In this paper, we describe a development scope and characteristics of the ITF such as, hardware and software development scope and characteristics, system thermohydraulic modelling characteristics, and experiment station characteristics for the experiment variables design and control, to be used as an experiment environment for the evaluation of VDU-based control room.
