In this paper a free-form hull design program and performance prediction program for planing boat is introduced. This program enables the designer to do complex geometric hull shape design on a personal computer and accurately to predict power requirements for a given loading and velocity. For a free form design, Bezier curve model is adopted as a basic representation tool of curves and surfaces, and this program has versatile functions to do fairing jobs with a convenient graphical user interface. After creating a hull form the geometric data is provided in a manner compatible with a variety of analysis tools including 'Motion Analysis(by Zarnick)' for prediction of motion characteristics in regular waves, 'Running Attitude (by Savitsky)' for prediction of the running attitude and required power.

In this paper, we purpose the integrated TMS to solve the problem of current systems. Current system resulted in the inconvenience because customer and user must contact to each systems when they want to know the information about the order. In this time, we make the system customer and user can confirm all of order information from one system to solve this problem by integrating the information brought from two systems on constructing integrated DataBase.

In this paper, we consider an integrated inventory system where a single supplier purchases and processes raw materials in order to deliver finished goods to a single buyer for effective implementation of Just-In-Time purchasing. An integrated JIT lot-spl

One of the recent trends of cockpit development is to integrate the part of whole cockpit and compartment. The goal of this study is to develop and Analyze User's Convenience for a cockpit prototype based on the design guide of cockpit integration module. The process of this study has been followed analyzing development trend of next generation Automotive cockpit, extracting the design factor needed to making integration module and laying down the design guide of cockpit integration module. After that process, next-generation Automotive cockpit has been embodied as graphical image designing. Henceforth, applying this module to real will be considered after evaluation of utilization. THis study is indicated that one example for evaluation of utilization.

Manufacturing technologies of compound semiconductor are similar to the process of memory device, but management technology of manufacturing process for compound semiconductor is not enough developed. Semiconductor manufacturing environment also has been emerged as mass customization and open foundry service so integrated manufacturing system is needed. In this study we design the integrated manufacturing system for compound semiconductor fabrication that has monitoring of process, reduction of lead-time, obedience of due-dates and so on. This study presents integrated manufacturing system having database system that based on web and data acquisition system. And we will implement them in the actual compound semiconductor fabrication.

This paper address the Integrated inventory system for JIT purchasing where a single vendor purchases and processes raw-materials in order to deliver finished-items to buyer. A mathematical model and an iteration solution procedure is developed to find the order interval for each item and number of shipment between buyer and supplier simultaneously.

EPC seeks to minimize variability by transferring the output variable to a related process input(controllable) variable, while SPC seeks to reduce variability by detecting and eliminating assignable causes of variation. Tn the case of product control, a very reasonable objective is to try to minimize the variance of the output deviations from the target or set point. We consider an alternative EPC model with second-order autoregressed disturbance. We compare three control systems; EPC, EPC combined system with EWMA, CUSUM and Shewhart. This paper shows through simulation that the performance of the integrated model of EPC and SPC is more preferable than that of EPC.

Nowadays, Internet-based businesses is activated in various organizations. In most of distribution and manufacturing companies, the main current of internet businesses is on-line sales (B2C: Business-to-Customer) centering around internet shopping. Most of theses businesses applied contents-centered and customer-oriented methodology for implementing internet business system(IBS). Also, recently, Introduction of Internet-based VAN(Value Added Network) systems and e-Procurement systems of purchase fields between parent companies and suppliers are proliferated for an efficiency of business and a reduction of transaction cost. These systems used methods of re-constructing the existing legacy systems into Internet-based systems. This paper proposes a customer-oriented and process-based methodology that simultaneously considers customer requirements and business processes of operational systems in order to implement an Internet business system. To demonstrate the usefulness of the proposed methodology, we applied and implemented an Internet business system for sales of A/S (After Service) spare parts and services on the object of the "H" company of manufacturing ship engines, which is a make-to-order corporation. As a result, This paper showed an effective applicability of Internet-based e-business on A/S business processes in order to improve a service quality for customer satisfaction in manufacturing companies.

As the certifications of ISO 9001/1400, OHSAS 18001(not official standard) is increasing, it is needed to construct a integrated management system(IMS) for the efficient operation. This paper deals with the types of integration of management of the various areas of interest -Quality, Environment, Safety and Health. Second, this presents how an integrated management system could be developed, implemented and operated through case studies.

Various numerical models that have been developed for marine environments and applied to coastal waters in USA were introduced briefly. Inter alia, with regard to an integrated monitoring and modeling system, the main features and outline of system, the system architecture for data management and representation system, and the incorporation of internet based technology were described. An example of application of an integrated system to coastal waters was also presented. The prospective research works to improve the capabilities and to advance the functionality of an integrated monitoring, modeling and management system were suggested to be the instrumentations for various monitoring parameters, the new development and/or advancement of various numerical models, the relevant internet based technologies. etc..

Chinese character is forms of letters, which our ancestors first got access to and was the one and only letters in ancient East Asia. It was Korea where Chinese characters had spread its roots for the first time in the process of spreading to surrounding nations. And therefore, as a form of letters which was with the long history of the Korean race, it became the parent body of Korean language, and became Korean vocabulary itself. Today, we are living in the age where all it takes to write Chinese characters o computer is to just press the transfer key on the keyboard, even if you can`t accurate write the letter. The result of performing clinical testing in the fields of personal education apart from established system of education for around 8years by developing the drill sheets for the integrated study using the Chinese characters was that the abilities of the students grow. It was significantly proven that the student who had used Chinese letters since their elementary school years naturally stand out in language abilities in high school and tend to possess excellent ability in understanding the surrounding and creativeness. The 21st century is the age of intelligence informatization, and children today are the main leaders of the 21st century. Learning of Chinese characters through integrated study of the children whose brain would actively develop will be highlighted as a new genre of education.
