UDDI is the open standard for distributed Web-based registry standard which supports registrations and discoveries of Web services. Recently, UDDI version 3.0 specifications were opened by OASIS UDDI Spec, technical committee. UDDI version 3.0 supports many useful functions, which are not supported in version 2.0 specification, such as nested query, enhanced find qualifiers, digital signatures subscription, etc. Despite of its merits, complexity of the standard and backward-compatibility support makes it difficult to adopt this standard in real application domains. In this paper, we develop the Registry server which support UDDI version 3.0 standard. This server is based on common RDBMS and it supports all functions of UDDI version 3.0 including backward-compatibility with version 2.0 API, XML digital signature and URI- based key schemes.

This appendix deals with the Korean air interface standard, TTA-62, for CDMA Mobile Systems, (CMS) [1]-[2]. The standard has been set up by Telecommunications Technology Association (TTA) which is a standardization organization in Korea [3]. This standard is an important specification that should be determined prior to the development of a digital cellular system. The CMS has been developed on the basis of this standard and the papers published in this special issue are the results of the CMS development. This appendix also describes the technical commonality of these papers. It covers the outline of the air interface and protocol specifications. The outline includes its major characteristics, radio protocol architecture, functionalties, and call processing. A comparison is also given between TTA-62 and IS-95[4], a North American digital cellular standard.

Recently, there have been many studies on RFID-based SCM. Yet, studies of synchronizing errors caused by tracking logistics information in supply chain, and activating & monitoring RFID infra is still insufficient. Also, there is no case of developing the intelligent SCM system enabling total monitoring and controlling RFID Infra by applying these technologies. Logistics information synchronization based Smart SCM model is intelligent supply chain service model to monitor the status of the RFID equipments in supply chain and the synchronization of the logistics process in each logistics point through one integrated view, as well as to react instantly by providing the information to help the various decision makings, when the emergency occurs. By adopting global logistics standard, RFID related standard specification, EPCIS standard, and SSI middleware platform, this model provides the domestic standard specification.

ERC-20, the standard API for Ethereum token smart contracts, was introduced to ensure compatibility among applications such as wallets and decentralized exchanges. However, many compatibility vulnerability problems have existed because there is no rigorous functional specifications for each API nor conformance review tools for the standard. In this paper, we proposed a new review procedure and a tool to perform the procedure to review if ERC-20 token smart contract programs for the Ethereum blockchain conform to the de facto standards. Based on the knowledge from an analysis on the ERC-20 API functional behavior of the top 100 token smart contract programs in the existing Ethereum blockchain, a new specification for the de facto standard for ERC-20 API was explicitly defined. The new specification enabled us to design a systematic review method for Ethereum smart contract programs. We developed a tool to support this review method and we evaluated a few benchmark programs with the tool.

This research suggest the correspondent sizes of women's and men's ready-made clothes to export to China on the basis of KS size specification. The results of this study, with the cooperation of Sejung and Searte Companies exporting clothes to Ningbo City, Zhejiang Province in China, are as follows: 1. Corresponding Dimensions of China Women's Clothes According to Morrison's relative deviation method, the body measurement characteristics of Chines and Korean women in their 30s and 40s were compared. As a result, Chinese women were bigger in height, arm length, abdomen girth, and upper arm girth but smaller in shoulder length and shoulder width. The cluster analysis for body type classification was as follows: Type 1, tall and well-developed, was 34.8%. Type 2 with weaker upper body, medium height, narrow shoulders and a slim waist was 45%. Type 3 with stronger upper body, shortest height and wide shoulders was 20.2%. 2. Corresponding Dimensions of China Men's Clothes Based on the drop standard of KS K 0050, the body types of Chinese men in their 20s were classified. A body types were 55.77%, Y body types were 32.16%, B body types were 11.55% and BB body types were 1.51%. According to the criteria of ready-made dimensions of normal body type suggested in Korea Standards, and in consideration of the basic distribution reality of body dimensions, representative 5 sizes were selected. 3. The corresponding size specification of China women's and men's clothes based on those of KS size specification were presented here, showing product sizes and physical items in detail.

Due to the increasing complexity of embedded system design, automatic code generation of embedded software and hardware-software co-design methodologies are gaining great interest from industries and academia. Such an automatic design methodologies are always demanding a formal system specification languages for defining designer's idea clearly and precisely. In this paper, we propose automatic embedded C code generation from SDL (Specification and Description Language, ITU-T recommended the SDL as a standard system description language) with considering a real-time uC/OS-II operating system. Our automatic embedded C code generator is expected to provide a fast specification, verification and performance evaluation platform for embedded software designs.

Aero-pulsation noise, generally caused by geometric asymmetry of a rotating device, is considerable source of annoyance in passenger cars using the turbocharged diesel engine. Main source of this noise is the compressor wheel in the turbocharger system, and can be reduced by after-treatment such as silencers, but which may increase the manufacturing cost. More effective solution is to improve the geometric symmetry over all, or to control the quality of components by sorting out inferior ones. The latter is more effective and reasonable than the former in view of manufacturing. So, an appropriate discrimination method should be needed to evaluate aero-pulsation noise level at the production line. In this paper, we introduce the accurate method which can measure the noise level of aeropulsation and also present its evaluation criteria. Besides verifying the reliability of a measurement system - a rig test system -, we analyze the correlation between the results from rig tests and those from vehicle tests. The gage R&R method is carried out to check the repeatability of measurements over 25 samples. From the result, we propose the standard specification which can discriminate inferior products from superior ones on the basis of aero-pulsation noise level.

In seismic analysis, there are two main ways - uniform load method and dynamic analysis, dynamic analysis can be divided into response spectrum analysis and time history analysis. In case of which get the complexion of the vibration with 3-axis of coordinate direction in each mode of free vibration mode happened owing to complication of the shape, 3-dimensional dynamic analysis is recommended to perform as multi-mode spectral analysis in standard specification for highway bridge. The purpose of this study is to understand the dynamic behavior by performing multi-mode seismic analysis according to responses analysis and time history anal)'sis in using record of earthquake. In accordance with the criterion of seismic design as defined in standard specification for highway bridge by using modified records of the El Centre and Coyote Lake earthquake, response spectrum was constructed by using the tripartite logarithmic plot. The 3-span continuous space truss bridge was selected as model of numerical analysis. As the result performed time history analysis and analysis of response spectrum for the model of numerical analysis, the result of time history analysis was slightly larger than that of response spectrum analysis. This coincide with the tendency of the result came from the analysis when using a jagged response spectrum analysis, This coincide with the tendency of the result came from the analysis when using a jagged response spectrum for a single excitation. In the Process of performing these two analysis. response spectrum analysis is more effective than time history analysis in saving times in analyzing data.
