This study investigates and analyzes (1) the status of neighborhood commercial facilities, (2) the location of neighborhood commercial facilities and (3) the users' viewpoint of them for the purpose of establishing the revitalizing factors of neighborhood commercial facilities within permanent rental housing complexes. This study attempts to determine the factors that revitalize neighborhood commercial facilities through quantitative factor analysis based on the analysis of the basic status and purpose of neighborhood commercial facilities using the basic status of permanent rental housing complexes and the quantitative data on neighborhood commercial facilities within these complexes. A survey investigating the residents' perception of neighborhood commercial facilities was conducted to analyze the qualitative aspects neighborhood commercial facilities within permanent rental housing complexes. The factors affecting the revitalization of neighborhood commercial facilities were analyzed by quantifying the actual problems perceived by the users and the elements of their use patterns. From these analysis results, it was found that the factors are not independent from one another, but organically affect one another. It is expected that more meaningful data will be obtained if future studies conduct correlation analysis and weighted value analysis on each factor based on the findings of the present study.

This paper describes the design and implementation of a PC(personal computer) based open architecture machine tool controller. The hardware of open architecture CNC has generally a motion control board on a PC for controlling a servo motor. But this paper describes open architecture hardware that consists of a PC, a counter board a DAC board and a DIO board only. This makes it easy to generate CNC software module in a hardware-independent way. The proposed open architecture CNC software runs on the MS-Windows NT. The paper describes a method of con-trolling servo motors using a real-time timer of MS-Windows NT and a commercial real-time operating system on the MS-Windows. NT. An open and reconfigurable software module is made up of an object and an API(application programming interface). Using the object and the API a new CNC system can be quickly configured to control dif-ferent machine tools. The proposed open architecture CNC system is applied to 4-axis lettering center.

Recently, urban mixed-use commercial facilities have been required to raise a safe environment in public areas. So, this study focuses on analyze planning factors selected through the precedent research for Pedestrian safety and environment of urban mixed-use commercial facilities. The first purpose of this study is to analyse the applicative estimation of environmental plan to support pedestrians in public space of urban mixed-use commercial facilities in Seoul. And the second purpose of this study is to propose the directions of environmental planning for creating a pedestrian-friendly environment in public space of urban mixed-use commercial facilities. In order to accomplish this purpose, the environmental planning factors for supporting pedestrians and guidelines for disabled shown in the precedent studies are drawn. A survey of research subjects are 4 urban mixed-use commercial facilities located in downtown Seoul. And then a questionnaire survey is performed on architecture and interior design students to evaluate the importance. As a result of the study, the following conclusion are drawn. The pedestrian-friendly environment in urban mixed-use commercial facilities requires planning to strengthen accessibility, supporting and safety of public space.

This study aims for proposing improvement method for streetscape in a small and medium city of Korea. According to this purpose, in chapter 2, by inspecting conservation of street environment and streetscape, deduce the frame for analyzing streetscape in commercial district. In chapter 3, analyzing present condition and problems of selected streets in Pohang City, derive the primary factors to induce desirable streetscape through problems and their reason between the analyzed elements of building form. Analyzed elements are composed of floor elements, wall elements, ceiling elements. The detailed elements are pavement of road, street furniture, height of buildings, color and material of building and outdoor advertisements. In chapter 4, by conducting a questionnaire survey of pedestrians about street images -choosing impressive physical elements and the feeling of the street by the list of adjective of semantic differential scale- and the preference, propose the direction of improvement about streetscape in commercial district.

The importance and cost of avionics system in the integration of an aircraft is continuously increasing. And we can expect enlarged software portion in the system integration for the more intelligent, reliable, and automated avionics system. Both military and commercial avionics community have moved toward commercial-off-the-shelf(COTS) equipment and open systems architecture not only to increase affordability but also to reduce acquisition cost, shorten development time and risk. The same concept is applied in developing avionics test system used for the avionics system integration test. In this paper, we present important topics in the development of avionics system including real-time operating system, interconnect data bus, software development methodology, software development process, and system integration test.

The purpose of this study is aimed at grasping the architectural characteristics of modern buildings in Gangneung from 1910's to 1970's. The results are as follows. 1) The commercial buildings are mostly unsymmetrical flat type and others except commercial buildings are mostly symmetrical flat type. 2)Up until the 1940's, staircases were located inner of building between the first and the second floor, however after the 1950's, they were separately located in one side of the building to ensure perpendicularly more space and easier mobility than before. 3)Windows were widely used in order to avoid monotonous wall elevation after 1950' s. 4)Striped decorations were put to use to decorate the front elevation of building. 5)Parapet which had decorative stripes to the top was generally used to hide roof.

In this study the relative effects among trees, cars, wires and building facades on visual preference are measured with the photo-montage scenes, which were synthesized by computer graphic programs. In addition to these experiments, the interaction of each elements of streetscapes have been investigated. The results of this study can be summarized as follows ; (1) It was found that trees had a remarkable positive effect on preference for streetscapes, wires had a moderate negative effect, cars had a trivial effect and the effects of building facades were medium. (2) It was investigated that the building of residential type was most preferred among commercial, residential, and office building types. The next preferred building facade was the commercial type. (3) The interaction of each element of streetscapes also have effects on preference. Especially, it was found that the combined effects of building-wire and building-cars were more notable than other combined effects of two elements.

The purpose of this study is to evaluate the biotope structure of the city center area of Jung-gu for nature experiences and recreation purposes. Jung-gu is the most extremely and rapidly urbanized area of Daegu. This study was conducted under the assumption that the biotope structure of a city center area would be different from the urban area. The results of this study are as follows: 1) There are 11 biotope type groups as designated as commercial and work-area biotope type group, and 41 detailed biotope types designated as commercial areas with a lack of greenspace biotope type. 2) The commercial and work area biotope type group has the largest area with 34% of the total area, and the square biotope type group has the smallest area with 34% of total area. 3) The result of primary biotope evaluation is that there are 12 biotope types that have greater than third grade, apart from the biotope type of park that includes natural vegetation. The first grade of biotope type has not appeared in this area, however, the fifth grade of biotope type has 20 biotope types with the biotope type of construction work area (JA). 4) The results of the secondary biotope evaluation are 1 biotope for la, 9 biotopes for 2a, 9 biotopes for 2b, 14 biotopes for 2c and no biotope for 2a. This study suggests that a detailed investigation and improvement plan for high-value biotope areas in the city center area must be continued.
