This study purposed to investigate the optimal outrigger location in tall building with cap truss after a structural schematic design of 80 stories building was performed by using MIDAS-Gen. In this paper, the main parameters of structural analysis were the outrigger location and stiffness of main structural elements (outrigger, exterior column, shear wall etc). In order to search the optimal outrigger position in high-rise building with cap truss, we analysed and examined the lateral displacement of top floor which is one of the very important considering factors of tall building structural design. The paper results indicated that the outrigger location and the stiffness of main structural elements such as outrigger, exterior column and shear wall had an effect on the optimal outrigger location. And it is verified that the study results provided the basic engineering data for fixing the most optimal outrigger location for minimizing the lateral displacement of tall building.

Advanced Intelligent Network(AIN) and X.500 directory service have similarity in between. X.500 capabilities and the requirements for the Service Control Function(SCF) to Service Data Function(SDF) in AIN. As an interface, SCF can be mapping as a Directory User Agent(DUA) and SDF can be mapping as a Directory System Agent(DSA). Based on the concepts, X.500 directory can be applied to AIN. In this paper we suggest to apply the X.500 DSP to the SDF/SDF interface to perform a distribution function. Also we show that the SCF-SDF/SDF-SDF relationship can be possible under applying X.500 DAP/DSP within the set of Capability Set 1 (CS1),CS2 and CS3. Finally, based on the above contents, we introduce the designed schematic of AIN SDF Server System for a distributed processing in AIN and design the X.500 schema of Universal Personal Telecommunication(UPT) service for supporting AIN SDF Server.

Automated rebar fabrication, which requires effective information exchange between model designers and fabricators, has brought the integration and interoperability of data from different sources to the notice of both academics and industry practitioners. Industry Foundation Classes (IFC) was one of the most commonly used data formats to represent the semantic information of prefabricated components in buildings, whereas the data format utilized by rebar fabrication machine is BundesVereinigung der Bausoftware (BVBS), which is a numerical data structure exchanging reinforcement information through ASCII encoded files. Seamless transformation between IFC and BVBS empowers the automated rebar fabrication and improve the construction productivity. In order to improve data interoperability between IFC and BVBS, this study presents an IFC extension based on the attributes required by automated rebar fabrication machines with the help of Information Delivery Manual (IDM) and Model View Definition (MVD). IDM is applied to describe and display the information needed for the design, construction and operation of projects, whereas MVD is a subset of IFC schema used to describe the automated rebar fabrication workflow. Firstly, with a rich pool of vocabularies practitioners, OmniClass is used in information exchange between IFC and BVBS, providing a hierarchy classification structure for reinforcing elements. Then, using International Framework for Dictionaries (IFD), the usage of each attribute is defined in a more consistent manner to assist the data mapping process. Besides, in order to address missing information within automated fabrication process, a schematic data mapping diagram has been made to deliver IFC information from BIM models to BVBS format for better data interoperability among different software agents. A case study based on the data mapping will be presented to demonstrate the proposed IFC extension and how it could assist/facilitate the information management.

Considering the online idea generation, or web-storming, system would be used differently by space designers depending on their job characteristics, the present study tested the usability of web-storming using a factor correlation table with a designer group in the field. Then, for analyses, the results were compared with the previous findings on the usability of web-storming in a design administrator group to suggest comprehensive measures applicable to web-storming. The questionnaire results were analysed following a process of observation-interpretation-application, and the space design process and web-storming function factors were also analysed based on a factor correlation table. The analyses found that the most correlated space design process in both administrator and designer groups was the schematic design phase, and that the correlation started to lower upon division of labour. The assessment phase was found significantly different between the designer group and the administrator group. The assessment phase showed the second highest correlation in the designer group. In terms of the aspects related to project operation, the correlation was found higher in the designer group. Based on the findings, new applicable measures to each phase of web-storming were derived and summed up to suggest how to take advantage of web-storming in the field.

We propose and demonstrate an I/Q demodulator using four-port BPSK demodulator base on additive mixing and reflection-type phase shifter using hybrid technique. Previously, the conventional I/Q demodulator base on multiplicative or additive mixing method divides I/Q signal path from mixer to parallel-to-serial converter. In this paper, we propose new I/Q demodulator without dividing I/Q baseband signal path. The proposed schematic requires half size in implementation and half power consumption in baseband path compared with the conventional receiver. Also, the proposed receiver eliminates parallel-to-serial converter after data decoding. The proposed circuit has been successfully demodulated a QPSK signal with the L-band carrier frequency and 20 Mbps data rate.
