The bogie of monorail vehicles applies rubber wheel system not steel wheel system. In addition, The structure of the bogie is very complicated because vehicle operates on the elevated road and vehicle drives with wrapping the guide way. When the monorail vehicle applies air brake system, lower device of vehicle may be complex and some devices may be limited. On the other hand, hydraulic brake equipment is compact and not weighing. Braking force is also outstanding compared with air brake so the hydraulic brake equipment is suitable for monorail vehicle. Also urban transit system such as monorail, applies mixed system both friction brake and electric brake in order to save electric energy. But application case of hydraulic brake in the country is very rare because hydraulic brake have difficulty in satisfaction of control requirement and maintenance. Therefore, this study suggests ways to design hydraulic brake system with blending brake for monorail vehicle and applies the ways to future monorail.

CTQ's choice is an important process for quality improvement. It is difficult to get customer satisfaction if CTQ is not chosen properly in view of improvement effort. However, case study or research about the supporting method for CTQ choice is not yet fully accomplished. In this paper, we propose an effective method for CTQ choice considering customer requirement through QFD as well as safety by using AHP which is one of strategic decision-making techniques for product safety. Also we show an empirical study on its application to the auto test robot system of mobile phone development.

This study analyzes a change and an effect that brand image gets in product choose. Purpose of this study present the suggestion under the influence of degree that brand image gets in product purchase to cosmetic customer. Consumers investigate the product or trademark when purchase goods. They purchase goods through the comparison and analysis and evaluate the satisfaction and dissatisfaction with the contentment. Consumers complicate while compare the products and the consumer's choose the products. The purpose of this study is find various requirement of consumers and present efficient marketing activity through theoretical verification and actual proof analysis.

Railway route maps including subways is a guide map which offers transport information as well as cartographic diagrams and is not only a way of communication, but it should give also concrete image and pleasing form. The elements of route map should meet satisfaction requirement condition and design attributes with aesthetic principles. To guide passengers by giving geographic information effectively, we need to understanding the following concepts and its application of basic elements such as expressing its structure and value. Therefore it should appear as a diagram with typography, form, symbols and colour. This means the aim of a good visualization should be done by a method that is concrete and a synthesis of well composed elements.

In order to determine home delivery service routes, conditions specified for each parcel such as customer-assigned delivery times and parcel contents should be considered, so the conventional route search algorithms have some limits to be applied for home delivery services. In this study, a multi-purpose route searching algorithm is suggested in order to deal with every requirement of deliveries that vary in delivery distances, contents and appointed times. A simulation study to verify the performances of the system with example data of Seoul and Kyungki provinces shows that it significantly improves the customer satisfaction and the productivity of delivery businesses.

The developer and user of weapon system must define the requirements of weapon system for the satisfaction of stakeholders and complexity of modern weapons in the developing process of weapon system. The perfect requirements reduce risks of the developing system in the initial step. It is not only economy of time and money but also good for the project of developing system. But, the perfect requirement is very difficult because of contradictions between the user and the developer, and limited conditions. So, the structured method and the process is needed for developing requirements.

The environment of the enterprise changes very quickly, and the customers' needs ate becoming to be various. Only the enterprise can be securing a competitive high position if the enterprise knows well with the customer. Therefore, the enterprise must be confronted appropriately which grasps the requirement of he customer. The Kano presents quality dualism, it complemented a different meaning problem point and the Timko presented the customer satisfaction coefficient. But the model of the Timko which committed the error as well that does not consider the indifferent quality of he Kano. Hence, with this research hat proposes the method of analyzes the client demands accurately through Modified CS-coefficient. Then, apply the method on to the multiplex theater.

This paper makes a detailed comparison between two metrics designed for measuring customer's satisfaction in the retail industry. The first metric, which is called the customer service level, has not been widely used due to the intrinsic requirement on the parameter assumption(s) of the demand distribution. Unlike the customer service level metric the in stock ratio metric does not require any requirements on the demand distribution. And the in stock ratio metric is also very easy to understand the meaning. To develop the detailed planning activities for business with the in stock ratio metric on hand one should collect some information as following : 1) POS (Point of sales) data, 2) Inventory Data 3) Inventory Trend.

It is very important for performance of information system that we make an effort to raise user's satisfaction by continuously grasping user's requirement by evaluation of PMIS based on ASP service quality and reflecting this to information system. However, It is lack that developments of suitable evaluation index of PMIS based on ASP service quality. Hereupon, In this study, we propose the evaluation indicators. First, The evaluation area is classified by form the foundation of D & M IS Success Model (2003); system quality, information quality, service quality. Second, The detail evaluation item which include considerations which are gotten through investigation of the construction industry and PMIS based on ASP is grouping by form the foundation SERVQUAL which is a service quality evaluation tool proposed PZB(1988). It is suitable to evaluate PMIS based on ASP service quality in construction industry and able to evaluate various aspects.

Advanced countries have mandated applying BIM in construction projects. Also, Public Procurement Service has planned to mandate applying BIM to all construction project that ordered in PPS from 2016 in KOREA. However, now Seumter that is building administration system is not supported BIM based construction license BIM information from Seumter. Thus, despite the applicant is preparing a BIM model, they do not take advantage of BIM information in Seumter. In previous studies. We developed a BIM based building approval submission system. In this study, we verified the system that developed in previous research. As a result, requirement information input time reduction in Seumter system showed high satisfaction. But there was as low usability because building approval submission system cannot support some information for building approval in seumter. If the system will do utilization and management with the building approval system, the applicant can be using BIM base design document information and saving the time that takes at building approval submission. Study about the system improvement is required for application to building approval system.
