MND(Ministry of National Defense) has developed MND AF(Ministry of National Defense Architecture Framework) and CADM(Core Architecture Data Model) to guarantee interoperability among defense information systems. TRM(Technical Reference Model) and SP(Standard Profile) product defined in MND AF is core part of Information Technology Architecture and core element of interoperability guarantee. In this paper, we proposed a method which manages technical service and standard of TRM and SP, and developed TRM and SP management system based on the method. TRM and SP management system provides the basis for interoperability among information systems and a more efficient development and management of TRM and SP product.

The purpose of this study is to establish work classification system of landscape construction in order to offer the basis of new estimation system of public landscape construction. New estimation system is based on historical construction data. For application of this system, the standard work classification system is necessary. Because extensive cost data should be accumulated under an unified construction work classification system. In the study of new estimation system carried by KICT(Korea Institute of Construction Technology), landscaping works belong to earth work of civil engineering. It looks very unreasonable work classification, because landscape archtecture has its own specialties and professional domain. In this study, information classification systems in the construction industry and various landscaping works of housing developments are analysed. As a result. a standard work classification system of housing landscape construction is proposed in section VI-3. This standard work classification structure consists of three levels divisions (i.e large work division, middle work division, small work division) . Now in this study, housing landscape construction works are divided into four large works and twenty six middle works. According to work attributes, middle and small work division is possible to subdivide into details.

This paper presents a method of constructing telematics terminal embedded architecture for DMB TPEG data service The proposed embedded architecture was designed for terminal. Also, we use WIPI which was used for standard based on mobile middle-ware, and TPEG decoding which was used for Window CE. We can see the advantage compare with previous methods.

In order to reduce blocking artifacts and improve compression efficiency, H.264/AVC standard employs an adaptive in-loop deblocking filter. This paper proposes a new hardware architecture of the deblocking filter that employs a four-stage pipelined structure with an efficient data distribution. The proposed architecture allows a simultaneous supply of eight data samples to fully utilize the pipelined filter in both horizontal and vertical filterings. This paper also presents a new filtering order and data reuse scheme between consecutive macroblock filterings to reduce the communication for external memory access. The number of required cycles for filtering one macroblock (MB) is 357 cycles when the proposed filter uses dual port SRAMs. This execution speed is only 41.3% of that of the fastest previous work.

This paper is to provide the method of dynamic service composition in ubiquitous environment. This method is extended of Service Component Architecture, which is a standard about service composition. This standard only supports service composition in system design time. It has problem we cannot it ubiquitous environment, requests dynamic service composition. To solve this problem, we suggest dynamic service composition method based on SCA.

In traditional approach, enterprise-wide consistent security policy enforcement for applications is very difficult task. Therefore, industry is now moving towards new unified enterprise application security concept that consist of centralized authentication and authorization mechanism. The eXtensible Access Control Markup Language (XACML); an XML-based standard defined by OASIS, is most suitable choice which can support centralized, role based, context aware access control mechanism. It is designed to provide universal standard for writing authorization policies and access control request/response language for managing access to the resources. This paper includes a brief overview on XACML and discusses its benefits, limitations and a data flow process. We propose a new generic access control architecture that supports enterprise wide centralized application level access control mechanism using XACML. The other benefits which can be achieved through this architecture are, reduce adnministration cost and complexity, support of heterogeneous computing platforms, centralized monitoring system, automatic fail over, scalability and availability, open standard based solution and secure communication.

Indoor thermal conditions greatly affect the health and comfort of humans who occupy the space in it. The purpose of this research is to analyze the influence of water and vegetation elements as a microclimate modifier in buildings to obtain thermal comfort through the study of thermal environment models. This research covers two objects, namely public buildings and housing in Makassar City, South Sulawesi Prov-ince - Indonesia. Quantitative methods through field surveys and measurements based on thermal and personal variables. Data analysis based on ASHRAE 55 2020 standard. The data was processed with a parametric statistical approach and then simulated with the Computational Fluid Dynamics (CFD) simulation method to find a thermal prediction model. The model was made by increasing the ventilation area by 2.0 m2, adding 10% vegetation with shade plant characteristics, moving water features in the form of fountains and increasing the pool area by 15% to obtain PMV + 0.23, PPD + 8%, TSV-1 - +0, Ta_25.7℃, and relative humidity 63.5 - 66%. The evaluation shows that the operating temperature can analyze the visitor's comfort temperature range of >80% and comply with the ASHRAE 55-2020 standard. It is concluded that water elements and indoor vegetation can be microclimate modifiers in buildings to create desired comfort conditions and adaptive con-trols in buildings such as the arrangement of water elements and vegetation and ventilation systems to provide passive cooling effects in buildings.

The present study deals with the propeller design for the standard new propeller series so called KF Series for 52ton class fishing vessel. The MAU or B series have been usually used for the fishing vessel's propeller, which are to be improved in consideration of the efficiency as well as the cavitation point of view. The high technology of propeller design has been applied to the design of 52ton class fishing vessel's propeller in the present study. The new designed series propellers will be validated by the experimental results whose data will be also used for the new series chart.

This paper investigates protocol architecture for a web-sensor gateway interconnecting internet and wireless sensor network, in which Zigbee sensors are connected over the IEEE802.15.4 communication protocol standard. The web-sensor gateway is to deliver data between TCP/IP and Zigbee/IEEE802.15.4 protocols, transparently. Since the gateway provides a means to remotely control and aggregate sensor data over the internet, it needs to be designed in the view point of users and in their convenience. In accordance, the common gateway interface technology satisfying users on the web browser to efficiently manage and query the sensors in the wireless sensor networks, ubiquitously, is also introduced. Finally, a simulation prototype for the web-sensor gateway is proposed and verified using OPNET simulation tool.
