  • 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.

  • The balance coefficients between telecommunication lines are specified in the technical standard and the power induction computation method varies in the order of 100 times in magnitude according to the amount of impedance. The results of actual balance measurements, differing from time to time with the measurement circuit or increasing proportionally as the induction voltage increases, appeared as a measurement error because of not using the standard measurement circuit. This article investigates such errors and proposes the use of a standard balance measurement circuit and a measurement device impedance under the domestic notification standard and the ITU-T international standard.

  • This paper analyzed the problems of the Korean output regulation in the relevant band through an analytic comparison of the current trend of each country and their standard values concerning electric field strength (technical standard) of weak wireless stations with less than 135kHz. In connection with the standard value of electric field strength of each country, which has been proposed in the registration of the appropriate electric wave, the paper aims to propose the standard value of electric field strength that could actually be introduced for suitable unauthorized wireless devices (weak wireless devices) in Korea. Provided that the Korean standard may be upgraded based on the tolerances of electric field strength proposed m this paper, this is expected to be committed to the distribution and advancement of weak wireless devices; and further it is anticipated to be prepared with competitiveness not only in the Korean communications market, but also in the international communications market.

  • This study set out to define a communication environment between an ITS center and field device required to be introduced in the nation in order to guarantee the interoperability, compatibility, and global competitiveness of communication between them in the nation. It also aimed to establish technical and policy plans for its introduction, develop an emulator for information exchange, and apply VMS by way of showing an example, thus testing its validity. First, a standard environment for information exchange between an ITS center and field device required to be introduced in the nation was defined as a dual protocol between DATEX and SNMP. The study also proposed a message definition system including meta-attribution definition and OID introduction. The study then suggested technical and policy plans for its introduction including securing enough feasibility with feedback through a model project of standard introduction, offering education and promotions for the standard in advance, providing methods to introduce and systematically manage OID, developing a hardware standard proper for the information exchange standard, and setting up an integrated management system to introduce a dual protocol.

  • IDPF, which builds formats and copyright protection standards of eBooks, has announced ePUB 3.0 as a technical standard of eBooks in October, 2011. This standard includes methods how to represent eBooks and technical specifications to protect eBook content. While technical specifications for content protection describe how to represent encryption and digital signature techniques, they do not identify any technical standards for rights expression but just file names for storages of rights information. It does not provide any unification of copyright information representation and formats used by eBook service companies. When copyright protection techniques for eBooks are used, comparability among eBook readers cannot be expected, even though there is a standard of ePUB. This study suggests a method to maintain compatibility toward eBook DRM by using unified rights information process under circumstances where different eBook service companies use diverse methods. The standard reference software of the model proposed in this study, together with other results of this study, will be offered as a registered open software.

  • In the present, since a five-year plan for economic development which was started in the early 60's has been successfully promoted for a quarter century, with consolidation in a department of social welfare in our country the participation. in economic society for women is more required than any other times. As a professional occupation for women is incereaing through a high-standard specialization, I think the upbringing for productive woman expert who has a strong motive of accomplishment as a developed person as well as a technical and skilful capacity which can be contributed to the growth of organization is very important. So in this study, I am evaluating the technical disposition of character of professional nurses working with hospital and also trying to supply the basic data being served to th extension of a skillful ability as a nurse, understanding the important factor related to it. The research method applied here is that we used 527 of formed questionnaires which were distributed to 7 University and General Hospitals, somewhat large in a scale, located in Seoul as an analytical material. It was performed between October 11, 1988 and October 18, 1988. An implement which was invented by Cho Moo-Sung is used after being amended and supplemented, which can measure the disposition of professional character. The formation of questionnaires of the disposition of character is 26 totally, 10 for Open-disposition, 11 for Active-disposition, 5 for wise-disposition, and it was measured. 'Ye', or 'No' through an one-half-standard and the environment of hospital organization is composed 12 questions from one point of 'Very Good' to 5 points of 'Very Bad.' Collected materials were analysed through an electronic calculation into the average value, the standard deflection, percentage, person correlative number, $X^2-test, m$ stepwise multiple regression. Summarizing the result from this research is as follows; 1. The average age of the subjective person of this investigation is 28.6 and the average career as a nurse is 6.0 years. 2. The Open-disposition that technical nurses showed is mostly half and half. 3. The Active-disposition of professional nurses was discovered affirmative largely and what they said in their questionnaires describes that they are very active answering $88.2\%$ for the disposition of self-control, $87.3\%$ for the people who think the training more seriously. 4. It was found out that the wise·disposition of technical nurse showed $90.7\%$ of 'Yes' about a new alternative of inquisitive question and we can see a progressive and profound aspect here. 5. As technical character of nurses, mutual relations between Active-disposition, Active-disposition, and wise­disposition were very profitably revealed as 0.42 in justice relations and also suggested that relations between Open-disposition, Active-disposition, and wise-disposition are 0.27 and 0.20 respectively. 6. What nurses recognize about the environment of hospital organization is reasonably acceptable while they feel very bad about rewards and punishments showing average 3.1 comparing to average 2.2 about time­control each other. Considering the prosperity of Active-disposition upon the result what I mentioned above, th possibility which is contributed to the productive improvement of hospital organization is very great and I think it can be more developed as a professional woman who has a strong motive of accomplishment, in advance.

  • Although Life Cycle Cost (LCC) must be evaluated by experts, sometimes it may not allow a sufficient time for even the experienced LCC expert to make rational decisions. Therefore, it often ends with relatively comparing the final numbers. We have broken down 110 technical proposals that are actually bade and accepted for large construction projects, and then have analyzed the uncertainty of Maintenance and Energy (M&E) cost during building life cycle, which turns out be the most volatile factor in uncertainty of LCC. Also we suggest "Value Engineering Index (VEI)" - the reduced M&E cost that is normalized by the reduced first cost. It is analyzed that the most uncertain factors of the M&E cost include repair and replacement term differing from each project, duplicated repair and replacement, non-standard repair items, and site-specific energy cost. Eventually we propose a VEI population with a mean of 1.38 and a standard deviation of 1.19, which is obtained by individually and exclusively applying the uncertain factors of the M&E cost to the 35 standard sample of technical proposals. The LCC evaluators may be able to use the VEI population as the benchmark to select the technical proposal with the most reasonable LCC among many others in two suggested manners; the one is to deterministically calculate the probability of single VEIs, and the other is to stochastically calculate the probability of the VEIs where uncertainty is quantified.
