Concurrent Engineering is one of the methods which are used for the rapid product development. One of the important features in Concurrent Egineering is that the development process is to be parallel and the organization should be cross-functional. In order that the process be parallel and that the organization be cross-functional, an integrated information system such as PDM (Product Data Management) is required. Although the integrated data base is constructed, it could be meaningless if the application softwares were not inter-operable. This study shows an example of intergrated information system from three-dimensional product design to mold design and tooling for the development of Deflection Yoke(DY) which is one of the important parts of Cathode Ray Tube(CRT). A three-dimensional product design software, which is based on a commercial code, has been developed by ourselves. Selective Laser Sintering(SLS), which is one of the rapid prototyping techniques, has been used in this study. Mold design has been done by the three-dimensional way. A newly developed method of mold tooling, which is called Quick Die Manufacturing(QDM), has been introduced.

In this paper, we developed the circuit and part information maintenance system based on JSP (Java Server Page) web server using web browser. Designers can easily search part information and register the new components or parts, and this system is linked to the EDA (Electronic Design Automation) system to be applicable to the circuit and part schematics in real time. Therefore, EDA system part library managed by individual designers are integrated into the web-based maintenance system.

Efforts are being made to prevent traffic accidents within the child protection zone. Efforts are being made to prevent accidents by enacting safety facilities and laws to prevent traffic accidents in the school zone. However, traffic accidents in school zones continue to occur. If the driver can know the situation in the child protection zone in advance, accidents can be reduced. In this paper, we design a camera that eliminates blind spots in school zones and a number recognition camera system that can collect pre-traffic information. Design a LIDAR system that recognizes vehicle speed and pedestrians. Design an LED guidance system that delivers information to drivers without smart devices. We study time series analysis and artificial intelligence algorithms that collect and process pedestrian and vehicle information recognized by cameras and LIDAR. In the artificial intelligence traffic accident prevention system learned by deep learning, before entering the school zone, the school zone information is sent to the driver through the Force Push Service and the school zone information is delivered to the driver on the LED sign. try to reduce accidents.

In this paper, a study on a method for designing and implementing an environmental information system to support environmental activities was done. First of all, research on the similar information system and necessary functions were derived. Necessary functions were largely classified into functions for cooperation such as policy consultation and publicity, and functions for environmental information data. Collaboration functions are classified in detail, and detailed contents of this function are summarized. In addition, a data model was designed for various environmental information, and an information server and client interface are designed as a cloud application. Cloud server configuration and design, and client web and app programs to access these information were implemented and tested each functions successfully.

As the marine transportation has increased, the safe maneuvering system has been required. SOLAS obligated regulations for carrying AIS(Automatic Identification System) onboard. This system provides navigational information including identification, classification, position, a ship's course and voyage status from own vessel to ground and other vessels. Being utilized in the most development of application service for safe maneuvering, they are to be managed systematic. In this paper, we introduce a database system to manage the voyage status and navigational information of AIS message. It is classified by static or dynamic. An electronic navigational chart display system is implemented to verify the design.

No organization can survive in today's modern society of information and high technology without internet and/or intranet. International convention industry is one of many high-technology dependent fields today which have started gathering new attention since the new millennium had begun. According to our survey, no professional convention organizer has used so far any type of integrated information system which is the vital source of support of the convention industry. Only the general purpose office softwares have been in use. The main purpose of this study is to design a model for ICIMS(International Convention Information Management System) to manage all the related information of international convention in a systematic and integrated way and to implement its prototype. International convention system in general had been analyzed to enhance the level of accuracy of the model for ICIMS. A simulation of an international conference was conducted to test the core module of the ICIMS model.

In order to obtain rigorous systems analysis and design, it is essential to understand accurate information flow in the system. For the effective capturing of accurate information flow in a system, it Is vital to control information flow in the system. Also, information and information flow have to be simplified as a deliverable form. This paper presents partitioning and conveyance technique based on the application of situation theory. First, historical background of situation theory will be given. Then necessary conditions and definitions will be provided. Lastly, this paper provides specific technique with example. This introduced technique will be a powerful tool for sharing timely and relevant information in a complex manufacturing system that can be used continuously and efficiently throughout systems operation.

Nepal is a sensitive and disaster-prone country where safety and security risk are of high concern for travelers. Digital technologies can play a vital role in addressing safety and security issues in the country. This research work proposes a Digital tourism security system design for addressing the safety and security issues in tourism industry of Nepal. The study uses Design science research methodology to identify artifacts, interactions, information flow and dependencies between them which are then mapped with existing prevalent technology to provide design solutions. Data is obtained from interview of tourist and experts as a primary source and technical documents/draft, software documentations, surveys as secondary source. Generalized information model, Use cases model, Network architecture model, Layered taxonomy model and Digital tourism technology reference model are the outcomes of the study. The work is very important as it talks specifically about implementation and integration of digital technologies in tourism security governance at federal, provincial, municipal and rural level. The research supplements as a knowledge document for design and implementation of digital tourism security system in practice. As there is very less work on digital systems in tourism security of Nepal, this work is a pioneer and first of its kind.

Classification and Coding(C&C) systems as a core of design information management have been accomplished by many studies in terms of design and manufacturing attribute based on Group Technology. Those are very difficult to apply in make-to-order(MTO) manufacturing because the environment of MTO has various characteristics of product, many licensors, engineering change, insufficiency of integrated management system for codes and so on. This paper presents a suitable C&C system to MTO manufacturing which consider management level and drawing.

This paper presents the design of multi-level logic optimization algorithm and the development of the SMILE system based on the algorithm. Considering the fanin constraints in algorithmic level, SMILE performs global and local optimization in a predefined sequence using heuristic information. Designed under the Sogang Silicon Compiler design environment, SMILE takes the SLIF netlist or Berkeley equation formats obtained from high-level synthesis process, and generates the optimized circuits in the same format. Experimental results show that SMILE produces the promising results for some circuits from MCNC benchmarks, comparable to the popularly used multi-level logic optimization system, MIS.
