The present work concerns the optimal design for injection molding processes by using the design of experiments (DOE) and numerical analysis. The DOE approaches is planned to be able to consider two-way interaction, and have been applied progressively for both mold design and process design. Numerical analyses have been carried out as a design of experiments for mold parameters such as runner specifications and cooling channel configurations. In order to determine optimal process parameters, experiments have been performed for various process conditions with the DOE scheduling. As a result, the quality and productivity of the product have been improved, and the proposed approach can be successfully reflected on the industrial injection molding process of precision electronics parts.

This study aims to investigate dynamic interaction characteristics between Maglev train and 3 span continuous guideway. The integrated model including a 3D full vehicle model based on multibody dynamics, flexible guideway by a modal superposition method, and levitation electromagnets with the feedback controller is proposed. The proposed model was applied to the Incheon Airport Maglev Railway to analyze the dynamic response of the vehicle and guideway from the numerical simulation. Using field test data of air gap and guideway deflections, obtained from the Incheon Airport Maglev Railway, the analysis method is verified. From the results, it is confirmed that Maglev railway system are designed and constructed safely according to the design criteria.

Today's firm runs on a customer-centric environment. Customers prefer to deal with companies that are accessible at anytime, from anywhere, in any form. Thix trend requires an ever-increasing number of channels to interact with the firm. And these channels ought to be integrated as well. To meet these challenges firms tend to rely on a customer interaction center (CIC) solution, enabling two-way interactions with customers through seamless contact channels. Though many firms these days tend to introduce the CIC into their organization, there is not much empirical research dealing with design elements that have to be fabricated in the CIC. This study is to investigate the relationship between CIC design elements and CIC effectiveness. To meet this objective we have contacted and surveyed a number of firms that are operating some form of CIC. We also describe a few success and failure cases in an effort to deliver issues or insights that should be considered in introducing CIC.

As KCI under U.S.D is impossible to calculate all sections compared P-M Interaction Curve of the circular concrete column under EC2 of limit state design and KCI. Result of the construction, P-M Interaction Curve according to design for standard is about the same. If a covering depth rased, EC2 is better safety than KCI.

Call Control eXtensible Markup (CCXML) is a standard language that supports a call control of voice dialog systems such as VoiceXML based systems. CCXML allows developers to handle telephony calls in an easy way without deep knowledge about telephony networks and their switching systems.We design and implement a call control markup interpreter. At the implementation, we use a Dialogic JCT-LS board, but, by designing a wrapping class for CTI (computer telephony board) features, the interpreter can easily adopt other CTI boards. We also design and implement event-based interaction scheme between the interpreter and voice dialog systems. For verifying the interaction scheme, we implement a simple voice dialog system.

These days, getting a gob is emerging as a hot social issue, and specialized sites offering job information are rapidly increasing. On the contrary of quantitative increase, job information sites have lots of problems with respect to satisfying customer's needs. This study is designed to explore web-site service quality factors in job information site, and relationship among characteristic web service quality, customer satisfaction, relationship quality and reuse intention. In this study we found that customer satisfaction is prior to relationship quality, which decide long-term customer relationship. And also, Trust which is one of the relationship quality and customer satisfaction affect customers reuse intent respectively. This study also found that characteristic service quality in related to job information site can be composed of four factors such as delivery of information, customization, web design and interaction. Delivery of information, web design and interaction affect trust, and web design and interaction affect customer satisfaction. And also relationship quality is prior to reuse intention.

Statistical design of experiments was successfully employed to investigate the effect of alternating magnetic field on activation of polycrystalline Si (p-Si) doped as n-type using $\textrm{PH}_3$, by full factorial design of three factors with two levels. In this design, the input variables are graphite size, alternating current, and activation time. The output parameter, sheet resistance, is analyzed in terms of the primary effects and multi-factor interactions. Notably, the three-factor interaction is calculated to be a dominant interaction. The interaction between graphite size and activation time and the main effect of current are important effects compared to the other variables and relevant interactions. Alternating magnetic flux activation is proved a significantly beneficial processing technique.
