In semiconductor IP reuse, precise understanding of semiconductor IP interfaces is essential for integrated chip design. However, in general, these interfaces are described in the original designer's description style. Furthermore, their description method are not unified, so it is very difficult for the chip integration designer to understand them. This paper proposes a standardized description method of semiconductor IP interfaces. It consists of 9 items such as IP information, description level, model provision, data type, interface information, port information, signal information, protocol information, and source file. The proposed method helps the chip integration designer to understand semiconductor IP interfaces and to integrate them into a single chip.

This paper describes implemation of 'General-purpose ETRI MAP interface module' (GEM) for Mini-MAP network. GEM operates as a Mini-MAP node in our FA system. To communicate between GEM and programmable devices(PD) such as PLC and CNC, serial communication is used. Application programs of a MiNi-MAP host system control and monitor programmable devices via GEM. GEM is implemented and tested on the basis of the MAP 3.0. TBC in the Nini-MAP board performs the function of the MAC sublayer. The LLC sublayer is implemented according to the specification of Class 3 that includes Type 1 and 3. And the MMS services are designed within the scope of implementation class MAP3. All the softwares are implemented under the real-time multitask OS for real-time application of the Mini-MAP and they are loaded into PROMs at the network board of GEM. We tested the LLC functions to make use of a protocol analyzer for the token-passing protocol. Also the MMS conformance test was carried out by exchanging primitives between GEM and a MMS product that had already passed the conformance test. Therefore GEM is proposed as a network tool of Computer Integrated Manufacturing (CIM) to integrate PDs which don't support MAP functions.

The Geography Markup Language (GML) is an XML encoding for the transport and storage of geographic information, including both the geometry and properties of geographic features. This paper uses the GML to provide extendibility and interoperability of spatial data in moving objects management system. Since the purpose of the system is to provide locations of the moving objects in the web and mobile environments, we used the GML both for presenting map data and trajectories of the moving objects. The proposed system is composed of Location Data Interface, Moving Objects Engine, and Web/Mobile Presentation Interface. We utilized the concept of Web Map Server, that is web mapping technology of OGC (Open Geospatial Consortium), to integrate map data and the location information of the moving objects. In the process of the integration, we used the standard data model and interfaces while defining new application schema. Since our suggested system uses open spatial data encoding and interfaces, both extendibility and interoperability are guaranteed.

Purpose: This paper presents a framework development for BIM (Building Information Modeling)-based OOPM (Object-Oriented Physical Modeling) for Building Thermal Simulation. The framework facilitates decision-making in the design process by integrating two object-oriented modeling approaches (BIM and OOPM) and efficiently providing object-based thermal simulation results into the BIM environment. Method: The framework consists of a system interface between BIM and OOPM-based building energy modeling (BEM) and the visualization of simulation results for building designers. The interface enables a BIM models to be translated into OOPM-based BEM automatically and the thermal simulation from the created BEM model immediately. The visualization module enables the simulation results to be presented in BIM for building designers to comprehend the relationships between design decisions and the building performances. For the framework implementation, we utilized the Modelica Buildings Library developed by the Lawrence Berkeley National Laboratory as a thermal simulation solver. We also conducted an experiment to validate the framework simulation results and demonstrate our framework. Result: This paper demonstrates a new methodology to integrate BIM and OOPM-based BEM for building thermal simulation, which enables an automatic translation BIM into OOPM-based BEM with high efficiency and accuracy.

The purpose of this research is to look for the best description of calculating the reasonable Landing Fee. Landing Fee is consisted one of major revenues for maintaining an airport. Traditional Landing Fee Rate has been charged based on the weight factor; Maximum take-off weight, Maximum landing weight, or Maximum authorized weight. To achieve a better reliable value of Landing Fee Rate, The elements of Noise and Peak-Time have to be considered as well as the aircraft weight. This research designs the algorithms for calculating Landing Fee Rate and also Landing Fee, based on the aircraft weight. The Network is also applied to above. That is, CGI(Common Gate Interface) is constructed to interface the terminal of calculating Landing Fee Rate, and the terminal of collecting and transmitting the data such as the Weight. The computer language on the CGI was made by C++ and PERL. The main point of this research is to integrate the airport and Information System and to construct the database which is based on the different perspective of calculating Landing Fee Rate. However, the result of the most efficient and reliable will be computed based on above. This research will broaden the range of application up to the each case of airports.

In aviation, with the rapid transformation of the mobility industry, UAMs are emerging to operate green low-altitude airspace in urban environments. In order for UAM aircraft to fly safely transporting passengers and cargo in low-altitude urban airspace, a traffic control system that supports the safe operation of the aircraft is essential. In particular, traffic control systems that reflect the characteristics of the flight environment, such as operating at low altitude in urban environments for a short period of time, are required. In this study, we define the definition of UATM and its main services that perform traffic control for the safe operation of UAMs. In addition, we analyzed the development trends of UATM systems based on domestic and overseas cases. Based on these analyses, we present the results of the concept design of the UATM system. After analyzing UATM development cases, we found that there is no commercialized UATM system, but overseas development is focused on systems that can integrate ATM and UTM. And we identified key stakeholders and interface data, and performed UATM system architecture and functional design based on the identified data. Finally, as a necessary element for the future development of UATM systems, we propose the establishment and advancement of UAM traffic flow management systems, the establishment of integrated control systems, and the development of interface with aircraft operation systems in preparation for the unmanned UAM aircraft.

Many people are the latest interested in the integration of the WWW and database systems. The UCM(United CGI Management) system, which is proposed on this study, is based on the method using CGI that does not change existing servers and clients to integrate the WWW and database system. Since the CGI executable architecture executes a CGI program whenever the database is accessed, the system performance is reduced greatly when many request to the database are made simultaneously. However, the UCM system improves the system performance since it uses the integrated CGI running a daemon process. Moreover, the proposed system can use the WWW database more economically and doesn't use the SQL because it does not use a DBMS. In UCM system, we define the extended HTML tags to implement the WWW database interface and use the EXODUS storage manager for accessing the database.

The virtual Korean keyboard system is a method of inputting characters by touching a fixed position. This system is very inconvenient for people who have difficulty moving their fingers. To alleviate this problem, this paper proposes an efficient framework that enables keyboard input and handwriting through video and user motion obtained through the RGB camera of the mobile device. To develop this system, we use face recognition to calculate control coordinates from the input video, and develop an interface that can input and combine Hangul using this coordinate value. The control position calculated based on face recognition acts as a pointer to select and transfer the letters on the keyboard, and finally combines the transmitted letters to integrate them to perform the Hangul keyboard function. The result of this paper is an efficient writing system that utilizes face recognition technology, and using this system is expected to improve the communication and special education environment for people with physical disabilities as well as the general public.
