This study was conducted to apply the modular construction method to Han-ok. The modular method, which is differentiated from the existing one, means a construction method that equipments, windows and interior materials are prefabricated as a six-sided object at a plant and then they are assembled at the least process on the spot. As for the theoretical observation, the theoretical basis to apply the modular method to the modular housing and Hanok was divided into environmental and economic aspect. In order to apply the modular method to Hanok, the unit scale and size were selected and the plane of unit module Hanok was developed. And a standard with regard to the unit combination and material lifting transportation method was set and planned. In addition, through the comparison the unit modular Hanok to the existing Hanok, the difference was analyzed and the strength was identified in terms fo design method, structure, construction method, period and cost. In final, the conclusion, with regard to the economic, technical application in future, was drawn through arranging the study contents. The unit modular Hanok to carry out the high-quality dwelling through construction period reduction, standardized construction materials and improved insulation performance can meet the demands for a paradigm of new construction technology.

Increasing the old and the senile disability, it is increased that the demand of barrier-free house for the disabled, the senior, the pregnant and the young is strongly increasing recently. In this reason, this study focuses the problems of the house which is used by the Blind through the investigation of current status and tries to find out the differences between disability's demand and current design of their house. As well, through the research and analysis some cases of the residential alterations this study verifies what the demand is on each room and their need is committed correctly during the residential alterations. It is the purposes of this study finding the problems through these research and analysis. Thus this study investigates houses of the Blind and finds out their house type, scale and daily life through the statistical data and documentary survey and also, investigates current status of their house. The basic standard for the current status and the demand analysis is researched by the barrier factors which are deducted from the former study.

Real Time Transport Protocol (RTP) is the Internet standard protocol for transport of real time data audio/video IP Telephony, Multimedia Seivece. In case of 8kbps voice codec, the size of packet per data is 20bytes and become more large to minimal 40bytes with adding each layer's header in RTP/UDP/IP. To solve this problem, various header compression skill were suggested on point-to-point networks. But it compress even IP header and cannot be suitable to apply to end-to-end network Thus, We will renew header compression protocol to apply wired router-based network.

SNOMED CT is a standard clinical terminology to provide a standardized way to record and manage clinical records for EMR or EHR. The structure of SNOMED CT is very complex because of huge expressive power and its internal design mechanism. Although there are some SNOMED CT browsers for browsing and searching SNOMED CT concepts, they are less effective because they do not consider such complexity of SNOMED CT. This paper depicts problems of current SNOMED CT browsers and analyze SNOMED CT dataset. Then, this paper analyze requirements of SNOMED CT browser which improves searching and selecting of appropriate clinical terms.

To efficiently execute 3D graphic APIs, such as OpenGL and Direct3D, special purpose arithmetic unit(SFU) which supports floating-point sine, cosine, reciprocal, inverse square root, base-two exponential, and logarithmic operations is designed. The SFU uses second order minimax approximation method and lookup table method to satisfy both error less than 2 ulp(unit in the last place) and high speed operation. The designed circuit has about 2.3-ns delay time under 65nm CMOS standard cell library and consists of about 23,300 gates. Due to its maximum performance of 400 MFLOPS and high accuracy, it can be efficiently applicable to mobile 3D graphics application.

The user has to subscribe to the library so that user use the library service. User has to register at that in order to use of the nearby another library. Moreover, service such as the inter-library loan and returning my loan book to other library in which the mutual cooperation between the library is needed necessity. But it services due to the constraint condition because of the administrative or technical problems. In this paper excludes the administrative element. The web service model is forming the cluster based on the mutual cooperation between the technologically adjacent public library and provides the technologically necessary single sign-on (SSO) in order to support the additional service. The single sign-on of the library which is concluded by this model using the security information exchange standard (Security Assertion Markup Language : SAML), it is processed by XML base. In using this model, the loan information is confirmed in the attribution in return service library and the model can utilize for the return of loan book in other library. It designs the single sign-on about it.

In line with the sharp increase of container traffic from globalization, ships have become larger with an aim of improving the maritime transport capacity in addition to the growing interest in monitoring danger areas on ships considering the quantity increase of ships, along with the tightening of international standard for ship safety by IMO(international Maritime Organization). Korea established a location based ship accident forecasting and preventing system in 2012 by Korea Coast Guard, however its poor response in ship accidents has been pointed out in the wake of the recent disaster of Sewol ferry. To resolve this problem, this study attempts to design a wearable type, instant emergency response system that has DGPS to issue an alert on danger areas and automatically send ship's location and operation information in emergency situation.

This study was about design and development of the Mobile Learning Evaluation Announced Systems, which could operate the e-learning and send the result of that to the parents. From this, teachers and parent can communicate with each other dynamically. Especially, this system does not simply present results of student' learning but provide the extra learning which can make up for student' wrong questions in the base of the evaluation standard. this paper suggests this total learning solution so that parents can perceive the state of their children's learning under the mobile learning environment.

RAID(Redundant mays of inexpensive disks) were proposed as a way to use parallelism between multiple disks to improve aggregate I/O performance. The emerging of intelligent I/O architecture provides a standard for high performance I/O subsystems and introducer intelligence at the hardware level. With an embedded processor, intelligent I/O adaptors can offload the major I/O processing workload from the CPU and, at the same time, increase the I/O performance. This parer addresses the essential issue in the design of disk scheduling for intelligent I/O devices. In this paper we compare with MB throughput per second and maximum I/O respond time in RAID.

The remarkable progress of electronics and radio communications technology has made our life abundant. On the other hand, the countermeasure of EMC becomes more important socially according to the increased use of electromagnetic waves. It had been required that the absorbing ability of an electromagnetic wave absorber is mote than 20 dB, the bandwidth of which is required through 30 MHz to 1,000 MHB for satisfying the international standard about an anechoic chamber lot EMl/EMS measurement. From November of 1998, however, the CISPR11 has accepted the extended frequency band from 30 MHz to 18 GHz in the bandwidth of EMI measurement. In this paper, we proposed the cutting corn-shaped type satisfying the above requirements and carried out broadband design using the equivalent material constants method. Moreover, we have fabricated it and compared its characteristics with simulated one.
