Social communications using information and communication technologies (ICT) for social interactions have been making a significant impact on task performance in organizations. However, most of the existing studies on ICT (e.g., telephone and email) have only focused on technical improvement of communication efficiencies (e.g., information exchange and storage). In this paper, we claim that ICT may be another alternative source of knowledge creation that enables employees to work, find solutions, and achieve their goals faster and better. We investigate the impact of ICT in terms of both tasks and social aspects with knowledge creation as task performance. Also, we investigate the moderating effect of media synchronicity on these relationships. This study contributes to the understanding of contemporary communications media usage and its performance in organizations. We collected and analyzed survey data of 248 company employees, using PLS. The results indicate that task urgency and social influence directly affect ICT usage, and even knowledge creation. Also the media synchronicity moderates the relationship between the characteristics of a given task and ICT usage and the relationship between ICT usage and knowledge creation. Theoretical and practical implications of these findings are also discussed in the paper.

This study evaluated the menus of native foods menu in the Jeonju city area in order to present possible improvements. The study examined twenty native food restaurants that target the visitors to the Jeonju city area from July 20 to August 12, 2005. These restaurants specialize in Jeonjubibimbap, Kongnamulgukbap, Hanjeongsik, and Dolsotbibimbap, which are all native foods of Jeonju. Restaurant patrons were randomly selected on leaving the study aim was explained, and questionnaires were distributed. of 200 papers, only 109 were suitable for statistical analysis. First, four factors of menu evaluation were drawn out: inner shape factor of food, outer shape factor of food, sanitation factor, and service factor. Second, the analysis showed statistically significant difference at the 5% significance level in age, job, and monthly income. Third, regression analysis between the factors on menu evaluation and the variables on their intention to visit the restaurant again, indicated that the inner shape factor of food influenced the intention to visit again. It is expected that these study results will assist the employees, restaurant managers, and chefs in making the best practical use of the basic ingredients to promote food quality and increase sales, which will lead to the further development of Jeonju city.

In a daily life these days, the safety and the comfort are considered very important. As the same as other areas, the good maintenance of fire protection systems and the fire drill plans in buildings can minimize the loss of human life and the property in case of fires. In this paper, a survey has been conducted to investigate the maintenance status of the fire protection systems of apartment buildings, shopping center and office buildings. Both practical procedures for checking the systems and for fire drills and strategic plans to minimize the losses in case of fires are suggested by analyzing how well the occupants in the buildings acknowledge the evacuation drills when the fire occurs.

The parameter design is the most emphasized measure by researchers for a new products development. It is critical for makers to achieve simultaneously in both the time-to-market production and the quality enhancement. However, there are difficulties in practical application, such as (1) complexity and nonlinear relationships co-existed among the system's inputs, outputs and control parameters, (2) interactions occurred among parameters, (3) where the adjustment factors of Taguchi's two-phase optimization procedure cannot be sure to exist in practice, and (4) for some reasons, the data became lost or were never available. For these incomplete data, the Taguchi methods cannot treat them well. Neural networks have a learning capability of fault tolerance and model free characteristics. These characteristics support the neural networks as a competitive tool in processing multivariable input-output implementation. The successful fields include diagnostics, robotics, scheduling, decision-making, prediction, etc. This research is a case study of spherical annealing model. In the beginning, an original model is used to pre-fix a model of parameter design. Then neural networks are introduced to achieve another model. Study results showed both of them could perform the highest spherical level of quality.

Despite all efforts, many product development projects fail and lead to an introduction of products that do not meet customers' expectations. In general, designers usually relies upon their past experiences of similar products as a source of design knowledge when they work on a new design project. Designers need a set of practical step-by-step tools and methods which ensure a understanding of customers' needs and requirements, as well as a past design experience knowledge. In this paper we propose a design initial value module for an excavator that proposes a key initial design parameter value in an early design stage to improve a design process on Customer Requirements. It makes possible to support designers more effectively, objectively, and easily. Also it can propose better products in terms of a customer satisfaction.

The purpose of this study was to empirically investigate the relationship among fashion brand experience, brand loyalty, relationship quality, and repurchase intention. The 420 survey questionnaires were distributed among the consumers in their 30s and 40s who had experience buy fashion brands products through convenience sampling in Seoul. Due to the reliability of data, 120 samples were discarded and 300 samples were put to actual analysis. By using SAS 9.4, data were analyzed for frequency analysis, reliability analysis, correlation analysis. The results of the study are as follows. First, the fashion brand experience which is consist of sensory, affective, behavioral and intellectual experience had positive effects on brand satisfaction and brand trust. Second, brand trust and brand commitment and the relationship quality of brand satisfaction, only satisfaction and commitment affects brand loyalty significantly. Lastly, brand loyalty had significantly effect on repurchase intention. It presented the potential to use the brand as a strategic tool to build strong brand assets, along with providing specific ways to secure differentiated competitiveness in the fashion brand market. It is also thought to be meaningful in that we presented a practical strategy to build and strengthen a lasting bond with consumers by looking at the impact on the quality of the relationship.

The understanding and prediction of the behavior of flow in open channels are important to the solution of a wide variety of practical flow problems in water resources engineering. Recently, frequent drought has increased the necessity of an effective water resources control and management of river flows for reserving instream flow. The objective of this study is to develop an efficient and accurate finite element model based on Streamline Upwind/Petrov-Galerkin(SU/PG) scheme for analyzing and predicting two dimensional flow features in complex natural rivers. Several tests were performed in developed all elements(4-Node, 6-Node, 8-Node elements) for the purpose of validation and verification of the developed model. The U-shaped channel of flow and natural river of flow were performed for tests. The results were compared with these of laboratory experiments and RMA-2 model. Such results showed that solutions of high order elements were better accurate and improved than those of linear elements. Also, the suggested model displayed reasonable velocity distribution compare to RMA-2 model in meandering domain for application of natural river flow. Accordingly, the developed finite element model is feasible and produces reliable results for simulation of two dimensional natural river flow. Also, One contribution of this study is to present that results can lead to significant gain in analyzing the accurate flow behavior associated with hydraulic structure such as weir and water intake station and flow of chute and pool.

This research presents a fashion adoption process model based on collective selection theory and examines the differences in the consumer adoption process of merchandising types at each stage of the fashion cycle. A questionnaire survey of 472 adult women was conducted for the purpose of empirical analysis of the fashion adoption process. The results show that fashionability and popularity (the primary attributes of fashion goods) have direct effects on resistance and adoption as well as indirectly through social compatibility and personal compatibility in the evaluation stage. In conclusion, on the theoretical side, this study verified the fashion process model according to consumer participation in the adoption process of fashion goods existing at different stage of the fashion cycle, internally through negotiating with individual tastes, and externally through interacting with others. On the practical side, this study presented an empirical result that can apply to merchandizing strategy centered on merchandizing type by connecting consumer adoption for the fashion goods released by actual companies.
