Document managements are very important in internal communication for good performance on projects. In case of small scale projects, the document management criteria often have very different from each of the cooperation departments and changes of document structure of work process are frequent over a project period. In this thesis, we propose a monitoring system of document management which is based on P2P(Peer-to-Peer). The proposed monitoring system of document management, which is based on P2P, makes up for time limits and a specific work process in small scale project groups. It can be managed focusing on work process and can monitor effectively the status of creations, sharing and distributions of documents. We can be installed at a low cost by using P2P in a small scale project.

This paper presents neural network-based recognition system for automatic light emitting diode (LED) inspection. The back-propagation neural network (BPNN) is proposed and tested. The current-voltage (I-V) characteristic data of LED from the inspection process is used for the network training and testing. This study selects 300 random samples as network training and employs 100 samples as network testing. The experimental results show that if the classification work is done well, the accuracy of recognition is 100%, and the testing speed of the proposed recognition system is almost one half faster than the traditional inspection system does. The proposed neural-network approach is successfully demonstrated by real data sets and can be effectively developed as a recognition system for a practical application purpose.

Recently many organizations have attempted to build hypermedia systems to expand their working areas to internet-based virtual work places. It is thus important to manage corporate hypermedia documents effectively. Metadata play a critical role for managing these documents. This paper identifies metadata roles and components to build its schema. Furthermore a meta-information system HyDoMiS(Hyperdocument Meta-information System) is proposed by the use of this metadata schema. HyDoMiS performs three functions metadata management search and reporting The metadata management function is concerned with workflow document and database. The system is more likely to help implement and maintsain hypermedia information system effectively.

In this paper, we developed a system that output and service using vairous contents with the inspection and management industry facilities in the operating system based on wireless network. This system can output to the display device at the same time, work management and a variety of content to the inspection facilities. And it outputs received contents of the advertising service provider in real-time. Therefore, this system support real-time facility management and various contents in the building at the same time.

As part of effort to reduce the process time from design to manufacture and delivery, the concept of CE(concurrent engineering) has been applied to design process. In this research, the drawing information management system (DIMS) was developed based on CE. The system can distribute electronic documents of drawing or work instruction parallel to all reviewers simultaneously and collect their annotations through network. Mark-up functions are used for annotations on the electronic documents. DIMS is a system which integrates drawing management, engineering BOM, CAD and raster drawings, etc. In this system, a SUN workstation is interfaced with PCs by LAN. CIMCAD-2D, Image Hunter, and ORACLE RDBMS are used for CAD drawings, raster drawings, and drawing information management, respectively. As an integration tool for all the information, LINKAGE is adopted.

Cloud services have become the core infrastructure of the digital economy as a basis for collecting, storing, and processing large amounts of data to trigger artificial intelligence-based services and industrial innovation. Recently, cloud services have been spotlighted as a means of responding to corporate crises and changes in the work environment in a national disaster caused by COVID-19. While the cloud is attracting attention, the speed of adoption and diffusion of cloud services is not being actively carried out due to the lack of trust among users and uncertainty about security, performance, and cost. This study compares and analyzes the "Cloud Service Quality and Performance Management System" and the "Cloud Service Certification System" and suggests complementary points and improvement measures for the cloud service quality and performance management system.

This study derived research model about the influencing factors of the successful performance of smart work. Research model is composed of four perspectives: technology perspective like system quality and usage level of information technology, interaction perspective like innovational climate, institutional perspective like personnel evaluation, and individual perspective like self-control. This study collected 155 survey data from K public company and M global software company. As a result of data analysis, all of four perspectives influenced smart work performance. Technology perspective had the strongest effect on smart work performance, the second was institution perspective, the third was interaction perspective, and the last was individual perspective. In conclusion, smart work is not an IT project. We have to reconsider the thinking that just only the introduction of cutting-edge IT increases business performance. Smart work project should be pursued in harmony with institution and climate in the organizational perspective and self-control in the personal perspective. Also, to maximize business performance in smart work environment, organizations should strengthen the positive factors and overcome the negative factors.

The purpose of this study is to examine the introduction and its application of objectives management system in practical case, This study attempts to describe, (1) the relationships between the objectives management and budget management (2) analyzed the introduced organization and applicable system for the performance of objectives. Concepts of objectives, as this study is adjusted as follows; i) Objectives must be operational. They must be capable of being converted into specific targets and specific assignments. Therefore, objectives are the basis for work and assignments; they determine the structure of the business, the key activities which must be discharged, and, above all, the allocation of people to tasks. ii) Setting objectives for investment requires also objectives for the structure, basic policies, jobs, and directions of the business itself. They are not selling objectives; They are genuine marketing objectives, and as such have to be built into the way the business itself is set up, directed, structured, and run.

The first line school system is complexed. In result school affairs is subdividing and complicating more and more. It increased school affairs of teachers and they spend more soluting of their work than studying of teaching materials . The performance evaluation was introduced into the management of school record work as a part of educational reform. This is the evaluation of a studying course and a heavy burden of teachers was aggravated. So they have to depend on computer. In this study. I want to present the efficient method of management of school record work by using Hnagul 97 and Hangul approach 97. That will be able to make out a record easily. It is possible to design a individual pattern and to alter it.

Optimum lot size calculation for real world manufacturing environment has been focused since last few decades. Several extensions have been made to the basic economic order and production order quantity models to realize the possible practical situations in industry. However, focus on work-in-process inventory has been ignored relatively. This paper provides a comprehensive review of the models developed for group technology based manufacturing environment focusing on work-in-process inventory. Models have been extended from a perfect manufacturing conditions to an imperfect manufacturing situation considering rework, rejection and inspection. Optimum lot size has been evaluated using a simple algebraic optimization approach. Significant parameters are highlighted using sensitivity analysis for the developed models. Numerical example is used to illustrate the utilization of such models in day-to-day production setups and the impact of significant factors' variation on total cost and optimum lot size.
