The rapid increase in the freight movement in Korea demands the improvement of the freight transportation system both in quantity and in quality. In recent studies integrated freight terminals have been suggested as the most relevant physical facility that solves this problem. This paper is aiming at the efficiency of the freight transportation system in Korea via integrated freight terminals. We develop a mixed integer programming model to determine simultaneously the most efficient freight flow patterns as well as the optimal locations and sizes of the integrated freight terminal facilities. The results of the model implication is also presented.

Domestic industry has a long history, but it has been suffering for a long time due to its poor competitiveness in management ability, supply of materials, technological development, sales marketing, and distribution networks. Moreover, the industry has not established its strong presence in the world market but is exposed to increasingly greater agonies because of inactive domestic demands, increase rate of import versus export, diversified government policies, and non-selective introduction of high-quality and low-priced foreign named brands of ceramics into the country. Theses factors have partly contributed to consumers' low or negative recognition.

More and more applications or demands for machine parts etc are expected for AISI 440C (hereinafter referred to as "440C") Stainless Steel because of its characteristic features, i.e. high-strength as well as high-corrosion resistance. This research has enabled us to obtain sintered products with good quality even under a wide range of temperature by utilizing the pinning effect of NbC, improving the relevant sintering feature of 440C Stainless Steel in the MIM method.

In this competitive era, it has become a prerequisite for the financial firms providing banking services to understand and meet the customers' needs and demands to remain competitive in today's market environment. Without satisfying the customers, banking business cannot stand alone. To satisfy customers, it is often recommended to provide better quality banking services to the bank customers. Providing quality banking services has become a prime strategic tool for the banking sector nowadays. Therefore, the study investigates the effect of various dimensions of service quality of banking service on customer satisfaction in a developing country, Bangladesh. A total of 212 walking Bangladeshi banking customers participated in this research. A structured questionnaire was developed based on past research. SPSS is utilized for analysis and Likert scale was used in this study. Internal consistency of all items was found correct and a total of seven hypotheses were proposed. For testing, a 5% significance level is considered for acceptance of hypothesis. The findings show that, except employee competency, all other variables such as reliability, assurance, tangibles, responsiveness, empathy, and access to service have positive influence on customer satisfaction. The study provides policy implications for the management boards of the banking sectors.

Increased over time are the market size of coffee shops and customer demands for coffee. This paper aims to provide solutions for quality improvement in products and services of coffee shops through a case study. SERVQUAL is adopted and modified for the given problem to identify customer requirements for services of coffee shops. Quality Function Deployment (QFD) is introduced as an effort to reflect customer requirements in engineering characteristics for products and services. This paper compares the market competitiveness of three coffee shops in a case study. This study also draws solutions for quality improvement in engineering characteristics for products and services by using QFD.

This paper proposes high quality of healthcare environments for a user-oriented children's hospital by identifying the user needs according to residential characteristics of the child, especially the hospitalization period. Caregivers, mostly parents of children in a children's hospital, participated in a questionnaire survey. The user's demands, satisfaction and hospital environment assessment were measured. A total of 103 copies of the questionnaire were finally collected and analyzed. The data was processed statistically using SPSS WIN 18.0 Version software. The results and conclusions are as follows. 1)The participants were categorized into three groups according to the hospitalization period of the child (less than 7 days, 7-20 days, and more than 21 days). 2)When the patients stayed longer in the hospital, their satisfaction was lower and their demands were higher. The long-term group required a more spacious bathroom for the child inpatients and their caregivers as well as sufficient individual storage spaces that are appropriate for the length of stay. 3)The longer they were hospitalized, the more negative they evaluated the hospital environment. These results suggest that the period of hospitalization is one of the crucial factors that impact the user's satisfaction and demands. Therefore, it is necessary to identify the design factors such as territoriality, privacy, accessability, and aesthetics to improve the satisfaction of the long-term child inpatients and their caregivers.
