For avoiding the waste of costs for building each mobile platform according to each mobile communication vender, KWISF proposed WIPI platform standard. Already the venders are providing mobile map services which are adapted on their own platforms. Because the integration of various mobile platform was performed to WIPI standard, the changes of platform and component API may cause the environment changes of mobile nap services. This study shows the design and implementation results of mobile map services adapted to WPI environments.

There can be some variation in the load carrying capacity of high-tension bolt friction joints when oversize bolt holes are made on the base plate and the cover plate. This study performed a static tensile test in order to examine the variation of slip load and slip coefficient according to standard bolt hole and oversize bolt hole in high-tension bolt friction joints. According to the results of the static tensile test, the slip coefficient changed to some degree according to oversize bolt holes on the base plate and the cover plate, but it was somewhat unreasonable to find a pattern in the change. Sliding strength showed a difference of up to 26% between the use of standard bolt holes and the use of oversize bolt holes. Because this exceeds the design sliding strength, however, its effect on the serviceability of joints under service load is insignificant. Thus, if the regulation on oversize bolt holes, which may be inevitable in making steel members, is applied flexibly, we may improve efficiency and economy in the design and construction of structures.

The annual energy demand of the standard rural house models was analyzed using the DesignBuilder. Indoor temperature set-point, U-value of outer wall, type of window, and degree of ventilation were selected as simulation parameters. In all the simulation cases, heating energy demand was higher than cooling energy demand regardless of the building size. When the lower U-value of the outer wall was applied to account for the thicker insulation layer, heating energy demand was decreased while cooling energy demand was increased. However, it is better to reduce the area of outer wall which is directly exposed to outdoor air because reducing the U-value of the outer wall is not effective in decreasing heating energy demand. Among the four different window types, the double skin window is most favorable because heating energy demand is the lowest. For a fixed infiltration rate, higher ventilation rate resulted in an increased heating energy demand and had minor impact on cooling energy demand. As long as the indoor air quality is acceptable, lower ventilation rate is favorable to reduce the annual energy demand.

This paper introduces a method of constructing expert systems in an integrated environment for automatic software design. This integrated environment may be applicable from top-level system architecture design, data flow diagram design down to flow chart and coding. The system is integrated with three CASE tools, FSD (Functional Structure Diagram), DFD (Data Flow Diagram) and structured chart PAD (Problem Analysis Diagram), and respective expert systems with automatic design capability by reusing past design. The construction way of these expert systems is based on systematic acquisition of design knowledge stemmed from a systematic design work process of well-matured developers. The design knowledge is automatically acquired from respective documents and stored in the respective knowledge bases. By reusing it, a similar software system may be designed automatically. In order to develop these expert systems in a short period, these design knowledge is expressed by the unified frame structure, functions of th expert system units are partitioned mono-functions and then standardized components. As a result, the design cost of an expert system can be reduced to standard work procedures. Another feature of this paper is to introduce the integrated environment for automatic software design. This system features an essentially zero start-up cost for automatic design resulting in substantial saving of design man-hours in the resulting in substantial saving of design man-hours in the design life cycle, and the expected increase in software productivity after enough design experiences are accumulated.

The introduction of the BIM into the architectural service industry is currently not being conducted smoothly. The purpose of this research is to, considering the current state of the market, establish long-term strategies that will enable the BIM to successfully settle. The survey has been conducted in target of architects in order to understand pending issues. Additionally, the articles regarding BIM have been researched for the purpose of better understanding the current societal demands. Indicated by survey results, the architects agree to a certain extent upon the need of BIM for architectural designs, yet also express concerns that the BIM introduction does not guarantee betterment in efficiency. The problematic aspects of BIM introduction that have already been discussed in some policy-related studies include a multitude of complicated issues that are unable to be resolved within a short period of time: underdeveloped BIM infra, the limit of BIM software itself, political issues regarding licensing and lack of social awareness. Based on the issues mentioned above, three main areas of focus along with their respective practical strategies and tasks have been designated. Finally, this research has analyzed the current situation and its issues along with the political solutions of 12 projects, amongst which include the standard for plan drawings, licensing system improvement, cost standard and BIM introduction support. Finally this research has analyzed the current situations and its' issues along with the political solutions of 12 projects, amongst them are the standard for plan drawings, licensing system improvement, cost standard and BIM introduction support.

TCP/IP is the most commonly used protocol to communicate among servers, and is used in a wide range of applications. Unfortunately, Data transmission through TCP/IP places a very heavy burden on host CPUs. And it hardly makes another job to be processed. So, TOE(TCP/IP Offload Engine) is considered in many servers. But, most of TOE modules tends to not support binary compatibility for standard socket interfaces. So, it has problems that existing applications should be modified and recompiled to get advantage of TOE device. In this paper, to resolve upper problems, we suppose design and implementation of TOE module supporting binary compatibility for standard socket interfaces. Also, it can make a usage of multiple TOEs and NICs simultaneously.

The purpose of this research is to improve sustainable clothes care by comparing household washer's standard course and quick course. Detergency at each course was classified by laundry weight, detergent concentration, and soils. Also, fabric damage from each course was compared. Washing experiments were carried out using two types of washing machines and three types of detergents. Using the standard soiled fabrics of EMPA 108 set, detergency was compared by laundry weight, soil, and detergent concentration. Additionally, fabric damage was evaluated using the mechanical action of MA-40. The results of the research were as follows. First, a standard course, having more working time exhibited better detergency than a quick course. However, the detergency deviation under 6kg laundry weight was as low as 9.0%. Second, detergency by the type of soil was more effective in standard course than in a quick course, but hydrophilic protein soils had a small detergency deviation at 7.6%. Moreover, hydrophobic oil, complex, and particulate soils had a higher deviation at 19.7% Third, fabric damage was in proportion to operating time. Fourth, a quick course showed approximately 80% detergency regardless of the type of detergent. in the case of using 50% of the recommended allowance by the detergent manufacturer. In conclusion, reducing the operating washing time and detergent concentration is in accordance with increasing sustainability, in the case of washing with lightly soiled fabrics under 6kg of laundry weight.

A helideck is one of the essential structures in offshore platforms for the transportation of goods and operating personnel between land and offshore sites. As such, it should be carefully designed and installed for the safety of the offshore platform. In this study, a structural design optimization method for a lightweight offshore helideck is developed based on a genetic algorithm and an attainable design set concept. A helideck consists of several types of structural members such as plates, girders, stiffeners, trusses, and support elements, and the dimensions of these members are typically pre-defined by manufacturers. Therefore, design sets are defined by collecting the standard section data for these members from the American Institute of Steel Construction (AISC), and integer section labels are assigned as design variables in the genetic algorithm. The objective is to minimize the total weight of the offshore helideck while satisfying the maximum allowable stress criterion under various loading conditions including self-weight, wind direction, landing position, and landing condition. In addition, the unity check process is also utilized for additional verification of structural safety against buckling failure of the helideck.
