From the early period of web design, there has discussed the need for style guide. But, it has not known specifically 'what it is' and 'how it should be applied'in the actual situation. Most web sites seem to be considered as 'would-be-same or similar'in those impressions. In case of domestic companies or corporations, the development of web style guide has been established, in addition to the trials to adopt Cl(corperate identity) into the web sites. In the universities, with the advent of the era of unlimited competitions among the universities, the need and the importance of web sites has been increasingly emphasized because most internet users, teenagers and twenties, have great interests in the universities and they actually constitute the university societies. But, in reality, the effort to adopt Ul(university identity) into the web sites has left so much to be desired. As one methodology, reflecting the characteristics of the university web sites and the financial reasons, it is assorted that the development of 'web style guide'is urgent. This report explains web style guide and its importance, in addition to the suggestion for the development of web style guide for the domestic university.

One of the most important aspects in multi-stage shape drawing is the proper design of the intermediate dies especially to provide adequate metal distribution. In the current study, a method for designing the intermediate dies has been developed to manufacture hollow linear motion guide rails by multi-stage shape drawing. The design method is based on the modified virtual die method. The effectiveness of the proposed design method was verified by FE-simulations and experiments using Mn55Cr carbon steel. From the results of the FE-simulations and the experiments, the proposed design method led to a drawn product with a sound shape. The dimensional tolerances of the product were within the allowable specified tolerances.

A computer code was developed to simulate both the thermal stresses introduced during the post-filling stage and the in-plane deformation after ejection process by finite element method based on the plane stress theory. The computer simulation was applied to the mold design of a 2 inch light guide plate (LGP) for thin film transistor (TFT)-liquid crystal displays (LCD). With injection molding experiments based on the design of experiments (DOE) technique, the influences of the processing conditions in injection molding on brightness and uniformity of the LGP were investigated, and the optimal processing parameters were selected to increase the brightness and uniformity. The verification experiment showed that the brightness and uniformity of the LGP were increased dramatically under the selected optimal processing conditions.

Three-dimensional experimental analysis was conducted in the pulverizer simplified isothermal model. The experiment model was constructed on a 1/3.5 scale of 500MW pulverizer. The purpose of this study is to investigate the effect of design parameters on the pulverized coal separator efficiency. Where used pulverized coal separator design parameters are guide vane angle, static classifier angle, dynamic classifier rpm. Taguchi method was used to find the effective design parameters related to pulverized coal separator efficiency. The results of the experiment showed that guide vane angle and dynamic classifier rpm were the design key parameters. In addition to the total number of experiment cases were reduced by Taguchi method.

In this study, experimental design methods were used to derive optimal process conditions for improving the thickness uniformity of a 0.40 mm, 3.5 inch light guide panel. Process mapping and expert group analysis were used to identify factors that influence the thickness of injection molded products. The key factors identified were mold temperature, mold temperature, injection speed, packing pressure, packing time, clamp force, and flash time. Considering the resin manufacturer's recommended process conditions and the process conditions for similar light guide plates, a three-level range was selected for the identified influencing factors. L27 orthogonal array process conditions were generated using the Taguchi method. Injection molding was performed using these L27 orthogonal array to mold the 3.5 inch light guide plates. Thickness measurements were then taken, and the results were analyzed using the signal-to-noise ratio to maximize the CpK value, leading to the determination of the optimal process conditions. The thickness uniformity of the product was analyzed by applying the derived optimum process conditions. The results showed a 97.5% improvement in the Cpk value of 3.22 compared to the process conditions used for similar light guide plates.

After the beginning of Web2.0 era, newly developed interaction design patterns based on Ajax(Asynchronous JavaScript and XML) have been tried in various Web2.0 services. These new interaction design patterns enable web service to provide rich experience for users. However, it is very hard to find organized task based guideline about Web2.0 interaction design even though there are a lot of complicated interaction design techniques and patterns. It is essential to have Web2.0 interaction guide based on Ajax because it can guide designers to use appropriate interaction design patterns and to keep usability for ordinary users. Therefore, this research aims to establish task based interaction design guideline for Web2.0 service based on Ajax. The reason why this research focused on Ajax is that Ajax is most widely used language for Web2.0 service. First, primary five interaction design patterns were defined through analysis of various interaction design patterns from Web2.0 services. Second, detail interaction design tasks from five major patterns were analyzed based on the study of major Web2.0 services such as Gmail, Twitter, YouTube and Google maps. Third, general design guidelines such as heuristic guidelines for web service are studied through literature review. After all, this study proposed task based interaction design guide for Web2.0 service with Ajax. With this guide, designers and developers can choose appropriate Web2.0 interaction patterns and apply to their service and provide service to users with enhanced usability and satisfaction.

As the interest in the millimeter wave frequency (30 ~300 GHz) increases, Nonradiative Dielectric (NRD) guide is being more attractive due to its low loss characteristics. Most of millimeter wave components, which can be realized with waveguide, can also be realized with NRD guide since NRD guide has similar dispersion characteristics and field patterns to waveguide. Previously, Variational Method was applied to the gap discontinuity problem to design a gap-coupled NRD bandpass filter. In this paper, the design procedure was simplified by replacing the air gap region with an equivalent circuit model of an evanescent waveguide using the fact that the NRD guide has a similar structure with a dielectric-filled metal waveguide. Prior to applying this design method to the bandpass filter of millimeter wave frequency range, a bandpass filter of which center frequency is 10 GHz(3-Pole, 0.1 dB ripple, 2% fractional bandwidth) was designed and fabricated. The measured result agrees with one simulated with HFSS within an error range of a fabrication.
