This paper proposes a context gathering system that obtains user's environment information from sensor and generates user's context profile. To design the system, we classify context and design context model based on traditional context-aware computing. The proposed system supports contexts adaptation service by gathering user's environment characteristics and biological characteristics and generating user profile.

This Study is to construct the Activity System Methods of Site Planning and Design. A planned spaces and facilities is considered usually in relation to users of space and facilities, user attributes, needs and values, and activity patterns. Information obtained form this study adds a qualitative dimension to the quantitative emphasis and supplies information for design-oriented analyses of site planning. In the design-oriented aspect, the concern is with devising desirable land use arrangements and facility supply considering objectives defined in the public interest. The design-oriented approache in site planning and design must use information on activity systems and space qualities in defining planning and design requirements of site development-one in the form of principles and standards of design used in land use and facility planning guidelines, and the other form of input variables for land use model and facility supply model.

Small and middle sized architectural design firms still have trouble using BIM (Building Information Modeling) for their tasks, which means that it is necessary to develop BIM Libraries and Technical contents. These BIM libraries should be based on common technical standards that reflect the technical contents to provide optimum BIM design support. This is essential to reduce the technological burden on the design office, because BIM does not just involve the 3D modeling of the design, but provides very important information for calculating the quantity of materials required for the construction and providing materials for the design work. Therefore, this research was aimed at improving the efficiency of the BIM design process by developing a system module based on the BIM technical contents data for the purpose of linking the BIM data and technical contents. The developed system module will be expanded to other uses of BIM in the long term.

It is known that about 15 to 40 percent of total design time is spent on retrieving information such as standard parts handbook data, engineering equations, previous designs. This paper describes a knowledge management system for machine tool design. Product structuring, change management, and complex design knowledge management are possible through the developed system. The system can speed up the design process by making necessary data instantly available as it is needed and keeping track of all the relevant design information and knowledge including individual decisions, design intentions, documents, and drawings.

In this paper, we introduce an integrated layout design system, SOLGER. Our system incorporates useful design tools : a powerful layout editor, a coherent access mechanism for large volumes of design data, an incremental design rule checker for hierarchical design environment, node extractor and electrical rule checker, a technology capture which is used for defining technology-specific information, and a procedural design environment for user customization. Also, we present a modified corner-stitching data structure which allows 45$^{\circ}$-angled bilateral edges. Users are provided with a multi-window design environment and a menu-driven interface. SOLGER is being used for VLSI designs practically.

An expert system was developed as a framework of integrating diverse and multifactored ergonomic knowledge to investigate its effectiveness in ergonomic workplace design and evolution. Although numerous computer-assisted approaches have been made to overcome the lack of integrated design principles, those models being used require very specific information of various design activities that may not be available in the design stage. On the other hand, an expert system would be an effective design aid that is capable of guiding the designer to solve a problem. However, most expert systems lack detailed evaluation capabilities due to a qualitative nature of inference mechanisms. Furthermore, those approaches were independently developed, focusing mostly on a single aspect such as biomechanics, physiology, etc. In this paper, a design framework was developed which takes advantage of expert system metholologies, a relational data base and existing ergonomic models. The pattern-directed, rule-based expert system allows the designer to gradually formulate and subsequently evaluate workplace design. A comprehensive and modularized knowledge base was built incorporating biomechanics, physiology and psychophysics, which is, in turn, capable of accessing not only qualitative knowledge but complex analytic evaluation models and massive information in the data base through an interface. A conflict resolution strategy using multiple criteria decision-making schemes was also employed to reconcile multiple design alternatives.

Iterative learning control is an approach to improve the transient response of systems that operate repetitively over a fixed time interval. It is useful for the system where the system output follows the different type input, in case of design or modeling uncertainty In this paper, we introduce the concept of iterative learning control and then apply the learning control algorithm for multi-motor system for performance Improvement.

This article shows a set of physical information fusion IoT systems that we designed for smart buildings. Its essence is a computer system that combines physical quantities in buildings with quantitative analysis and control. In the part of the Internet of Things, its mechanism is controlled by a monitoring system based on sensor networks and computer-based algorithms. Based on the design idea of the agent, we have realized human-machine interaction (HMI) and machine-machine interaction (MMI). Among them, HMI is realized through human-machine interaction, while MMI is realized through embedded computing, sensors, controllers, and execution. Device and wireless communication network. This article mainly focuses on the function of wireless sensor networks and MMI in environmental monitoring. This function plays a fundamental role in building security, environmental control, HVAC, and other smart building control systems. The article not only discusses various network applications and their implementation based on agent design but also demonstrates our collaborative information fusion strategy. This strategy can provide a stable incentive method for the system through collaborative information fusion when the sensor system is unstable in the physical measurements, thereby preventing system jitter and unstable response caused by uncertain disturbances and environmental factors. This article also gives the results of the system test. The results show that through the CPS interaction of HMI and MMI, the intelligent building IoT system can achieve comprehensive monitoring, thereby providing support and expansion for advanced automation management.

In developing total hospital information system, large amount of time and expense are to be spent while its results are likely to lead itself to end-users' dissatisfaction. Some of the main complaints on the part of end-users come from insufficient consideration of end-users environment as well as inappropriate representation of their requirement in the system alalysis and design. This papre addresses some advantages of Essential Logical Modeling Process for better analysis and design, explaining by example the developmental process of the Patent Management and Accounting System for a tertiary care hospital. In the case, the Essential Model, suggested by McMenamin and Palmer, proved to be an effective tool for clear separation of analysis and design phase and for better communication among system developers and with end-users. The modeling process itself contributed to better program modularity as well, shown in a Structured Chart. Difficulties in learning how to identify' essential activities' for the modeling practice were experienced in the beginnins stage, which were, however, overcome by elaborating some heuristic guideling and by rdferring to necessary tools including State Transition Diagram, Control Flow Diagram, and so many. While full evaluation of the Essential Model usag remains to wait till the completion of the case project, its strengt in making clear distinction between analysis and design phase was enough to be attractive to system analysts. The model concepts are open to many further application fields, particularly such areas as business re engineering, process remodeling, office automation, and organizational restructuring.
