Plot Units는 이야기를 형성하는 줄거리 또는 줄거리에 나오는 여러 사건을 하나로 구성하여 표현하는 단위이다. 한편, 개연규칙은 문장간 구성성분들의 개연적인 결속성을 나타낸다. 이러한 결속은 개연사슬로 나타낼 수 있다. 개연사슬은 개념을 연결하는 어휘들과 그 연결을 설명하는 관계들의 목록이다. 이중에서 기능관계순열로는 해당 개연규칙을 보다 개념적으로 설명할 수 있다. 본 논문에서는 이러한 기능관계순열을 분석하고 Plot Units과 비교해 보았다. 실험을 통하여 주어진 기능관계순열이 Plot Units의 어떤 유형에 해당하는지 알 수 있었다.

본 논문은 그래픽 처리 뿐 만 아니라 범용 연산의 가속화를 지원하기 위한 SIMT 구조 GP-GPU의 Dispatch Unit과 Operand Selection Unit을 제안한다. Warp Scheduler로부터 발행된 명령어에서 사용되는 Operand의 모든 정보를 Decoding 하면 불필요한 Operand Load가 발생하여 레지스터 부하가 발생 한다. 이러한 문제점을 해결하기 위해 Pre-decoding방법을 사용하여 Operand의 정보만을 먼저 Decoding 하여 Operand Load를 줄이고, 레지스터의 부하를 줄일 수 있는 방법을 제안한다. 제안하는 Dispatch Unit에서 나온 Operand 정보들을 레지스터 뱅크 충돌을 방지하는 방법을 적용한 Operand Selection Unit에 전달해 전체적인 처리 성능을 향상 시켰다. Modelsim 10.0b를 이용하여 Warp Scheduler로부터 발행된 10,000개의 임의의 명령어를 처리하여 소요되는 총 Clock Cycle을 측정하였다. 본 논문에서 제안한 Pre-Decoding 기능을 탑재한 Dispatch Unit과 Operand Selection Unit을 적용하여 기존의 방법들 보다 각각 약 11%, 24%의 처리 효율이 증가한 것을 확인 할 수 있었다.

The current architectural design of unit modular has been based on 2D of CAD program, so unit modular character which needs unit information management, as a dried-member system, has no effect on design process. The purpose of this study is We have developed a suitable BIM design process, according to various works of construction, then tried to contribute to supply and activation of the urban-life-housing based on unit modular. The BIM modeling process based on unit modular has been in order of unit combination with preparing manual classification, and, it has been constructed, at construction site, from housing foundation to roof finish by Bottom-up method. At a manufacturing factory, it has been produced in order of 1) grouping materials and parts, 2) fabricating unit boxes, and 3) interference examination of unit boxes, and each order has been classified as housing structure, architecture, plumbing process separately. At a construction site, the fabrication has been done in order of, like as a real housing construction scenario, 1) RC foundation work 2) unit module job-site-fabrication work, 3) roof truss work, 4) plumbing and HVAC work, and 5) housing interior finish work. After modeling process, the interference examination on each work of construction has finally completed modeling. The Unit modular utilizing BIM modeling can make easy housing maintenance through systematic control with preparing manual of unit module information, and securing accurate and speedy construction information. And it will promote design credibility and create maximum effect of unit modular construction method, such as construction period reduction and upgrade of construction quality, etc., through the computer simulation as real as construction environment in cyber space, and with the interfering examination.

In the presence of unit nonresponse we perform the calibration estimation procedure for the population total corresponding to the levels of auxiliary information and derive the Taylor and the Jackknife variance estimators of it. We study the nonresponse bias reduction and the variance stabilization, and then show the efficiency of the Taylor and the Jackknife variance estimators by simulation study.

The train configuration is based on one unit like basic 4 cars to multiple unit operation. Each unit has unique node such as train formation number. Some equipments(TC, CC) of TCMS are connected to the master TC through the LonWorks network. When the train is consist of multiple unit, TCMS has to implement quick network for data communication overall train. But a variable time delay is generated when it is performed communication with point to point type using train formation number. In this paper we propose new method to know the node information of adjacent unit. that is to add digital input signals notifying cab direction at any cabin. Also, we provide the optimized screen design that all collected information via network is displayed by each unit.

USM(Unit Service Management System) is the development tool and methodology to handling the event process in a U-City integrated platform by using the minimum unit services. USM can be one of the SOA development methodology. Minimum unit service has a minimum business logic that can be executed with input and output parameters. Minimum unit service consists of three parts : service profile, service input and output parameters and service execution information. USM provides two types of the execution method. One is module execution and the other is web service execution. The development of the event sinario by the USM development methodology can reduce the cost and duration of the u-service development by raising the rate of reusing minimum unit service.

The purpose of this study was to identify the factor structure of self-efficacy, consumer behavior, and the learning effects of the unit 'Consumption Life' and to study the effects of self-efficacy on the consumer behavior, and the learning effects of the unit 'Consumption Life'. Questionnaires were administered to 370 female middle school students living in the Metropolitan City of Daegu. The data was analyzed by using the frequency, descriptive statistics, factor analysis, reliability analysis, multiple regression, and t-test. The findings are as follow. Self-efficacy was composed of five factors such as the capability in work performance, rational performance, fear, anxiety, and the ability to challenge oneself. Consumer behavior was composed of five factors such as emphasis on product display, emphasis on information, emphasis on fashion, emphasis on appearance, and the products/information exchange. The learning effects of the unit 'Consumption Life' was composed of two factors in the economical consumption, and rational consumption. The effects of consumer behavior and the learning effects of the unit 'Consumption Life' on each of the self-efficacy factors like the capability in work performance, rational performance, fear, anxiety, the ability to challenge oneself were explained by factors such as emphasis on product display, emphasis on information, emphasis on fashion, emphasis on appearance and products/information exchange, and economical consumption and rational consumption.

This paper suggests a marginal probability model for analyzing repeated polytomous response data when some factors are nested in others in treatment structures on a larger experimental unit. As a repeated measures factor, time is considered on a smaller experimental unit. So, two different experiment sizes are considered. Each size of experimental unit has its own design structure and treatment structure, and the marginal probability model can be constructed from the structures for each size of experimental unit. Weighted least squares(WLS) methods are used for estimating fixed effects in the suggested model.

Image Processing은 Image Data가 대량이고 내재된 정보가 병렬로 연관성을 가진다는 측면에서 실시간 처리가 용이하지 알다. 본 연구에서는 High Speed Real Time Image Processing을 위한 IPU(Image Processing Unit)와 이를 구동하기 위한 High Speed Real Time image Processing Language인 IPASM(Image Processing Assembly)을 제안한다. 우선 IPU의 기본개념을 설명하고 IPU의 구현을 위한 IPLU(Image Processing Logic Unit)를 설계한다. 그 후 Window98환경에서 구동 가능한 IPASM Interpreter를 실제로 제작하여 IPU의 동작방식을 간접적으로 진단한다.
