The brand is getting more important purchase factor in apartment market, so domestic construction companies have tried to differentiate it from others using the unique brand image. The purpose of this study is to investigate consistency brand images as a process which includes publicity, design and customer service and to analyze how using intergrated brand image affects brand preference and purchasing intention. To examine hypotheses, empirical study survey questionnaire for consumers who reside in 4 different brand apartments in Dongtan, Hwasung city is conducted. The results of the study are expected to become the useful data in developing sustainable apartment brand and building the marketing strategy of construction companies.

The brand is getting more important purchase factor in apartment market, so domestic construction companies have tried to differentiate it from others by creating the unique brand image. The purpose of this study was to investigate consistency of apartment brand image as a process which includes publicity, design and customer service and to analyze how using intergrated brand image affects brand preference and purchasing intention. To examine hypotheses, an empirical study using a survey questionnaire for residents living in 4 different brand apartments in Dongtan, Hwasung city was conducted. The collected data were treated with the SPSS Win Program 14.0. The study indicates that residents living in brand apartment generally preferred natural friendly image, high-class image and modern image to the others. And at first apartment brand images were created with image advertising on TV, catalog for sale and model house tour, but residents have most needs for customer service reflected in brand images. The study also has found that brand images in each process including publicity, design and customer service were not intergrated. However brand image intergration had positive effects on residential satisfaction and customer loyalty. The results of the study are expected to become the useful data in developing sustainable apartment brands and building effective marketing strategy of construction companies.

The necessity of imformation on product design process is increased in recently years, because a product can be called a mass of information and becomes more complex as long as technology is developed. But the present product development method is like a relay race. In this sequential process, information is transferred from one department to other departments like \"over the wall\". And communication gaps among departments are generated, so imformation cannot be controlled very well. Therefore it is needed to innovate the design process. The information system proposedin this study is an application software which can be useful for integrated product design process. It has been developed primarily for use in IBN PC and windows environment. It comprises four functional modules; functions of handing the overall project information (document, ideaskech, rendering, drawing); functions of decision making production problems in design project process; functions of groupware which can link with other departments; functions of comprehensive database with production.roduction.

The objective of this paper is to provide an alternative framework for the integration of process planning and scheduling in cellular manufacturing. The concept of an integrated cellular manufacturing system is defined and the system architecture is presented. In an integrated cellular manufacturing system, there are three modules : the process planning module, the manufacturing-cell design module, and the cell-scheduling module. For each module, the tasks and their activities are explained.

This paper is the study of methodology for development of preliminary structural design modules for an intergated system for reinforced concrete structures. To develop the modules. it is used that the iteratived and incremental development process of object-orientied methodology and affects. The aspect is a tool to capture characteristics of the objects. The aspects consists of .user, structure, and system. By using aspects, we can find that objects and relationships between the objects consisting of the modules in the phases of process. In this paper, UML(Unified Modeling Language) is used to the notation. It serves as the language for communicating decisions that are not obvious and provides semantics to capture all important stategic and tactical decisions. Therefore such a series of mothods is valuable to development of preliminary structural design modules. Then preliminary structural design modules were programed by using Visusl C++, a windows environmental development tool.

Fault simulation for large and complex sequential circuits is highly cpu-intensive task in the intergrated circuit design process. In this paper, we propose CM-SIM, a concurrent fault simulator which employs an optimal memory management strategy and simple list operations. CM-SIM removes inefficiencies and uses new dynamic memory management strategies, using contiguous array memory. Consequently, we got improved performance and reduced memory usage in concurrent fault simulation.

This paper has proposed a 4- bit 20MHz Flash A/D converter design available analog signal processing and realized its intergrated circuit. The parallel comparison method A/D converter quantized analog signals swiftly using various converters. Also this theme has designed economic power dissipation circuit using a preamplifier of low volt & power CMOS comparator. Also the system was fabricated by Hynix 0.35um CMOS process.

Concurrent Engineering is one of the methods which are used for the rapid product development. One of the important features in Concurrent Egineering is that the development process is to be parallel and the organization should be cross-functional. In order that the process be parallel and that the organization be cross-functional, an integrated information system such as PDM (Product Data Management) is required. Although the integrated data base is constructed, it could be meaningless if the application softwares were not inter-operable. This study shows an example of intergrated information system from three-dimensional product design to mold design and tooling for the development of Deflection Yoke(DY) which is one of the important parts of Cathode Ray Tube(CRT). A three-dimensional product design software, which is based on a commercial code, has been developed by ourselves. Selective Laser Sintering(SLS), which is one of the rapid prototyping techniques, has been used in this study. Mold design has been done by the three-dimensional way. A newly developed method of mold tooling, which is called Quick Die Manufacturing(QDM), has been introduced.

기존의 관계형 데이터 모델은 복합 객체데이터의 표현, 임의의 데이터 정의ㆍ조작능력, 버전제어, 일반화, 집단화와 같은 의미모델 개념을 지원할 수 없어서 CAD/CAM, 동시 공학(CE), 컴퓨터 통합 생산 시스템(CIM)등의 분야에 응용이 사실상 어려운 문제점을 지니고 있다. 본 논문에서는 기존의 Booch 방법론, Rumbaugh 등의 OMT(Object Modeling Technique), 그리고 Jacobson의 OOSE 방법론 등을 조합하여 고안된 산업표준의 객체지향적 객체/설계 방법론인 UML(Unified Modeling Language)을 이용하여 선박용 핸드레일을 생산하는 기업체의 통합생산관리시스템(IPCS, Intergrated Production Control System)을 업무 기능에 따라 모듈별로 나누어 객체 지향 데이터 모델을 설계하였다. 이러한 객체지향적 데이터 모델의 구축은 생산공정의 효율적 관리, 시스템의 유지, 보수 및 확장을 원활하게 하여 경영합리화를 기대할 수 있다.

본 논문에서는 40 ㎓ 대역 MMIC(Monolithic Microwave Intergrated Circuit) 이중평형 star 혼합기를 비아 공정이 있는 GaAs substrate(두께 4 mil)상에서 설계 및 제작, 측정하였다. 이중평형 star 혼합기를 구현하기 위해 발룬회로와 다이오드 설계가 필요했다. 발룬회로는 microstrip과 CPS(Coplanar Strip)를 이용하여 새로운 구조를 제안하여, 2 ㎓ 대역으로 주파수를 낮추어 새로운 구조의 발룬 성능을 PCB로 제작하여 확인한 바 있다. 이를 바탕으로 40 ㎓에서 MMIC 발룬을 설계하였다. 제안된 발룬은 비아 공정이 포함된 MMIC 회로에 적 합하며, 이중평형 혼합기 구현에 쉽게 적용 가능하다는 특징이 있다. 다이오드는 p-HEMT를 사용하는 밀리미터파 대역의 다른 MMIC 회로들과의 호환성을 고려하여, p-HEMT 공정을 기반으로 한 쇼트키 다이오드를 설계하였다. 이를 이용 제안한 발룬회로와 다이오드를 조합하여, 이중평형 star 혼합기를 구현하였다. 혼합기의 측정 결과 LO전력이 18 ㏈m일 때, 변환손실 약 30 ㏈를 얻었다. 이는 p-HEMT의 AlGaAs/InGaAs 층에 의한 다이오드 때문이며, p-HEMT구조에서 AlGaAs층을 식각하여 단일 접합 다이오드를 만들면 혼합기의 성능이 개선될 것으로 예상된다.
