This paper describes the design of a multistandard video encoder. The proposed encoder accepts conventional NTSC/PAL video signals, It also processes he PAL-plus video signal which is now popular in Europe. The encoder consists of five major building functions which are letter-box converter, color space converter, digital filters, color modulator and timing generator. In order to support multistandard video signals, a programmable systolic architecture is adopted in designing various digital filters. Interpolation digital filters are also used to enhance signal-to-noise ratio of encoded video signals. The input to the encoder can be either YCbCr signal or RGB signal. The outputs re luminance(Y), chrominance(C), and composite video baseband(Y+C) signals. The architecture of the encoder is defined by using Matlab program and is modelled by using Veriflog-HDL language. The overall operation is verified by using various video signals, such as color bar patterns, ramp signals, and so on. The encoder contains 42K gates and is implemented by using 0.6um CMOS process.

This study is planning improvement of welfare facilities about the hall for the aged in apartment housing. An apartment house, famous residential type in Korea, put an important value on its convenience and economical efficiency of furniture arrangement by maximizing floor space index. In this regard, leisure usage of house was not carefully considered for the aged people. To redefine the efficiency of welfare facilities, research mainly deals with analysis of realistic needs for the aged through the spot survey and interview. The main purpose of this study is to enhance the quality of welfare facilities and propose the improved welfare facilities for the aged people. Through the research, conclusions are as followed First, Facility standard and provisions of the law should be revised for considering population growth of the aged people. Second, there are 4 plan types in the hall for the aged. Contrary to our expectation, diversity of program was not found however various program planning is needed for considering its different types of plan. Third, according to regulation, space restriction is based on the number of households. Therefore, room and space standard does not depend on the number of people. From now on, in order to improve quality of welfare facilities of the aged, revision of laws and overall facility standard should be implemented in advance.

This study examined the arrangement features in public library infant and children's reading room and provide basic material in after children's reading room space planning by studying the space features, which are valued in the environment behavioral point of view. We limited the check list to libraries built after year 2000 that are located around Seoul and from 5 libraries with children reading rooms. After analyzing items by the space features, considering children's environment behavior, pleasantness was most favorable, children scale, safety, comfortableness, flexibility followed in order. It shows the basic surroundings and the furniture that composes the children's reading room are relatively favorable, but in the other hand, it seems that reading rooms lack the ability to form an environment that can adapt to children's growth, inducting new activity areas flexibly or rearrange them. there are limitations to getting the children's needs objectively and significantly, so survey research, interview research and not only studying Korean's but comparing and analyzing with foreign country's cases will be needed.

This study aims to evaluate Rietveld's creative design style and concepts. To this end, I looked into the evaluation of major researchers on Rietveld, classified all his works into four groups according to the design types and analyzed them. As follows: based on the results of the analysis of works I concluded. First, Rietveld created the concept of the spatial extension to the ingenious joint which had the structural node formed of three listels with quadrangular section. It is the design innovation that led to liberate the closed construction. Second, Rietveld had opened up the possibility to neutralize the gravitational three-dimensional works. He subtracted the weight in the direction of gravity from the three-dimensional structure of the works and painted the three primary colors on them partially to get rid of the original material color. Therefore they looked like the forms liberated from gravity. Third, Rietveld ripped off the surfaces of cube through several formative experiments and decomposed the volume into the tesseract. Through this method of realizing the new plastic concepts, he completed the architectural models of weightlessness. Fourth, Rietveld opened the possibility of the realization of the three-dimensional works integrated all space and time in the one-pieced works and the folded works. Fifth, Rietveld steadily experimented and realized the internal and external integration of time and space in his later works.

Recently, the roof garden of the large commercial facilities has been changed as a complex cultural space follow the users' diverse needs. It is focused on large commercial facilities on Seoul and Gyeonggi area but large commercial facilities of the province still has not been able to respond to the needs of users. Thus, the present condition of roof gardens was compared space components with physical environmental factors in Seoul, Gyeonggi and Daejeon, Chungcheong. Throughout the comparison, roof gardens in Daejeon and Chungcheong area were focused on finding ways to improve As a result, roof gardens in Seoul and Gyeonggi area were applied to a variety of factors in space components experience, learning, performance, exhibition and etc. It is composed to take place of various acts in the roof garden. On the other hand, roof gardens in Daejeon and Chungcheong were not applied a variety space components by comparing Seoul and Gyeonggi area. Physical environmental factors also were insufficient by comparing Seoul and Gyeonggi area the landscape, awning facilities, amenities for handicapped. As described above, space components and physical environmental factors in Daejeon and Chungcheong area roof gardens were insufficient. To perform the role of the roof garden changing as a complex cultural space and to confront to the users' needs space component such as learning, performance, exhibition should be considered during planning. And physical environmental factors supportable space components should be considered together.

Relationship between body and space is fundamental in space design. The perception and concept of human body in each age directly affected the space makings of that time. Thoughts on human body are related to various periodical backgrounds such as culture, art, technology and etc. Body-Space relationship has been changed through different epochs and is being changed in the present time too. In contemporary cities, architectural programs has been fragmented and activities of individuals become more articulated. The rigidity of each architectural program has been forced to be more flexible amalgamation of diverse behaviors by dynamic urban time-space formations and patterns. Based on this current situations, new experimental designs that question the existing preconceived relationship between body and space in different views. These design experiments attempt to overcome the solid physical fixation of architectural buildings and to directly relate human body to intelligent devices, technologies, machines as well as spaces. This research focus on the innovative design projects in which body, machine, space are smartly compound as one organization. The purpose of this study is to examine the new Body-Space relationship as well as some relevant case projects in contemporary fashion, furniture, interior design and architecture.

This research studied the characteristics of the customer circulation in four department store food court restaurants located in Seoul. The characteristics of the customer circulation are the following: Before customers leave the dining space where they eat food, they come and go to spaces such as the water purifier space, the napkin storage, and the cup storage. On the other hand, they do not come and go from the dining space to the waste area or the area where used cups are returned. Therefore the spaces, that need to be located very near the dining space, are the water purifier space, the cup storage, and the napkin storage. The waste area does not have to be placed very near the dining area and the area where used cups are returned is not needed. A minority of customers drink water and use napkins after going to the waste area and the area where dirty dishes are kept. To prevent these customers from going against the circulation of the majority of customers, a water purifier space, a cup storage, and a napkin storage should be placed additionally connecting to the waste area and the area where dirty dishes are kept. For effective circulation plan and spatial composition of food court restaurants, these characteristics of customer circulation should be considered. It is not recommended to place the water purifier space, the napkin storage, and the cup storage, the waste area or the area where used cups are returned, and the hand cleansing facility in the same location just for the convenience of workers.

This study aims to find out the present conditions of pilotis space, and the usage and requests of it by residents as to suggest the direction in planning pilotis spaces in apartment housing. This study selected six apartment complexes, and conducted case-studies and surveys of them. The study findings are as follows. 1) The types of pilotis spaces of the apartment housing can be categorized into an entry type, a community type, a recreational type, a bicycle storage type, a pedestrian passage type, a parking type, and a visual passage type. As a result of studying the present conditions, pilotis spaces of a recreational type were the most, and a community type and a parking type were not found. It was found that diverse types of pilotis spaces need to be planned in consideration of the characteristics of an apartment complex and its residents. 2) As for residents' time spent in using the pilotis space, they spent little time. This can be attributed to the fact that most pilotis spaces were designed only with simple flat benches, and gazebos, which seemingly failed to draw residents' attention. Therefore, the spaces need to be planned for diverse purposes after examining residents' needs, which can include indoor exercise equipments and children's play facilities. 3) Regarding the residents' requests about pilotis spaces in the apartment housing, the most widely requested was using it as a community space. Also, many requested to use it as a library, and a children's play space. Therefore, it needs to be considered to plan the pilotis space for providing diverse programs.

This study is to understand the emotional tendency through out the history of architecture and interior design. In this process, a broad range of analysis of the period between Romanticism and Post Modernism will be done to collect historical data and the influence of the social situation. A thorough review and close examination of the 90's architectural trend will reveal the foundation of the concept behind GSD not just as the post-structuralism as a value system of digitalism but also makes easy to understand GSD in space design. In particular, the study will reveal how the ideas of post-structural philosophy has effected the formation of its movement as well as its influence to become the theoretical nutrition for digital architecture. The result of the study will be used as the valuable reference to define 'Emotional Design'(So call 'Gam-Sung Design = GSD) and become the foundation for further investigation on GSD space design in the near future.
