  • We followed the below procedure to establish the development strategy of CITIS standard. At first, we investigated Military CITIS and Commercial CITIS to establish the concept of CITIS and examined several implemented examples. And using the previous analysis, We analyzed the structure of the functions, the technologies and the standards. To establish the development strategy of CITIS standard, we divided CITIS standards into three category, These are infrastrucure standard, data standard and process standard. In the process standard, we analyzed how we develop a formulated process and which item we select to make formulated official documents. And finally, We explained the implementation plan and extension strategy of government-enterprise and inter-enterprise CITIS respectively.

  • This study focuses on applying performance-based design to construction standard in building construction. First, it realizes situation and issues of standard specification in building construction, deduces the need factors for establishing performance-based construction standard, and then, it proposes the application of performance standard. The required stages for deducing performance-based construction standard consist of dividing building parts, deducing required functions, performance items and performance requirement and deciding a method of performance evaluation. Through these stages, performance-based design process is deduced.

  • This paper describes the design and implementation of C standard library for real-time operating system Q+, that is being developed for the internet appliance. The C library in the real-time operating system should be defined according to the standard interface and support the concurrent execution of threads. The implemented C standard library is reentrant and follows POSIX.l standard interface. And, the C standard library functions, which are adequate to the Q+ application and commonly provided by commercial real-time operating systems, are selected among POSIX.l standard functions. The C standard library is implemented on the Q+ kernel and D-TV set-top box according to the implementation sequence, which is determined by analyzing the relation of function calls.

  • The safety standard for suspended access equipments(SAE) is developed. During the development of the safety standard, consideration was given to a close examination of the standards existing in other industrialized regions and nations such as the Eu.opean Union(EU), the United States, and Japan, as well as the existing domestic safety regulation. Also, a consideration was given to the appraising of the technical level and market conditions of the domestic industry. After careful examination of the current safety practices and issues, it was decided that the standard under development should closely follow those of the EU safety standard. The EU standard provides a detailed account of the calculation methods, safety and stability factors, testing apparatus and procedure, all under unified framework. A number of specific safety requirements have been modified in an effect to properly reflect the difficulties faced by the domestic industry. It is hoped that the safety standard developed here can serve as a valuable tool for policy decisions regarding worker safety.

  • Bsusiness-to- Business transactions requires interactions between diverse application s and business. This gives rise to the need to for a common standard and protocol for exchanging busienss messages. and RosettaNet is the leading industry organization focused on developing B2B process standard for a global supply chain. This paper is intended as an investigation of Build-up Method of SCM Connection applying EC Standard(Rossetta-net) to reduce the integration effort, and improve extensibility and interoperability of an eBusiness infrastructure.-Intiative way for E-commerce applications to quickly incorporate new standards. Supply Chain Management (SCM) helps companies plan and execute supply to meet customer demand. The researches of modem scientists have thrown new light on the subject. but, The study of SCM for EC Standard has been strangely neglected by critics. Consequently, existing SCM system, which require to introduce the functions of EC, needs to be changed. Let me summarize the main points that have been made in this paper. The sharing information for connection and the Rosetta-net standard of the existing SCM system, and PIP 3A4, order management module, of the Rosetta-net specifications for connection by the Rosetta-net. Lastly, That shows the process of the gateway for connecting among the existing SCM systems. This provides felxibility in incorporating any new emerging open standard.

  • The Standard penetration test determines the type of soil according to soil bearing capacity, and this classifies the subsoil into many layers. Construction project managers are willing to know the depth of the present types of subsoil on site in order to make plans on earthwork stage during excavation. However the standard penetration test may not provide accurate information on subsoil type due to incorrect spacing. To solve this problem, this study propose a conceptual algorithm for determining the spacing of standard penetration test spots to essentially tests relevant locations on which to be applied the standard penetration test. This provides the acquirement of the accurate layered model volume of earthwork revised into geological columnar section. This algorithm will determine the appropriate standard penetration test spots spacing on a given size of site to optimize the accuracy of the earthwork volume, time and cost.

  • The spectral responsivity of solar cells has been measured under high background irradiance using an LED-based differential spectral responsivity Comparator (DSR-C). The comparator developed is fully automated and has some advantages: It does not need a chopper to modulate the light. Unlike the conventional method, it does not require a monochromator to select wavelength. It covers a wavelength range up to 1200 nm. The wavelength range of the comparator is limited by the spectral power distribution of the LEDs and the spectral responsivity of the standard detector. An active temperature control was utilized to meet the specified standard conditions of solar cell test. This work shows the effect of different levels of background irradiance on the spectral responsivity and the importance of same background irradiance for solar cell test as specified by the corresponding standard.

  • This study entails establishing reference standard sand in Nigeria for engineering and geoenvironmental research work. Sands from four geographical locations in southwestern Nigeria were examined for baseline geotechnical and mineralogical properties. A total of sixteen sand samples were collected. The samples were air dried and subjected to tests in accordance with standard specifications. The tests carried out were: specific gravity, grain size analysis, moisture content, bulk density, porosity, void ratio, chemical analysis, X-ray diffraction and Differential Thermal Analysis. The properties of the samples were compared with a standard (Ottawa sand in Illinois of the United States) in order to find out which of the four samples selected from southwestern Nigeria could serve as standard baseline sand. The results show that Igbokoda sand has geotechnical and mineralogical characteristics closest to Ottawa sand. It was therefore concluded that Igbokoda sand could be used as a standard baseline sand for research work in southwestern Nigeria and other parts of Nigeria since it needs little processing to bring it to the same level as standard baseline sand, like the Ottawa sand.

  • It studies the non-structural crack factors that are produced in Steel Box Girder Bridge concrete floor plate using analytical method. It mainly studies humidity and design standard of concrete strength. It used MIDAS CIVIL Ver 5.4.0, a general structure analysis program that applies drying shrinkage rate of domestic road bridge design standard and standard value of creep coefficient, CEF-FIP standard equation and ACI standard equation from the aspect of creep, drying shrinkage and hydration heat to see the effect of the two factors on concrete crack and found the following result. The analytical results of this study showed that the initial stress, which was obtained by ACI standard, exceeds the allowable tensile stress between 5 to 18 days. This result means that even if a bridge is designed and constructed according to design standard, the bridge can have cracks due to various variables such as drying shrinkage, hydration heat and creep that produce stress in slab.
