Recently, the number of unsold apartments has been increasing, and apartment furnishing companies have tried a marketing strategy by utilizing the outdoor space for differentiation. There are many differentiation strategies. One of them is to improve the dwellings-on-ground space in apartment complex. Owing to the high density and high-rise of apartment buildings, the dwellings-on-ground apartment complex have been recognized as not good housing by residents in korea. The precedent study on the responses from residents showed the negative effects mainly due to sunlight, daylight, view and privacy and the positive effects from good accessibility and good environment for children and elderly people. The purpose of this study was to improve the dwellings-on-ground space and to suggest the most appropriate type of the dwellings-on-ground space through the residents' desires and preferences. In this point of view, this study shows three results for the design improvement: 1) Providing private gardens and individual accesses to the dwellings-on-ground. 2) Providing private garden with flower bed to intensify the visual aspect. 3) Furnishing variable transformation of unit plan in dwellings-on-ground, for example, maisonette, etc.

In this paper, the transmission of an improper-complex second-order stationary data sequence is considered over a strictly band-limited frequency-selective channel. It is assumed that the transmitter employs linear modulation and that the channel output is corrupted by additive proper-complex cyclostationary noise. Under the average transmit power constraint, the problem of minimizing the mean-squared error at the output of a widely linear receiver is formulated in the time domain to find the optimal transmit and receive waveforms. The optimization problem is converted into a frequency-domain problem by using the vectorized Fourier transform technique and put into the form of a double minimization. First, the widely linear receiver is optimized that requires, unlike the linear receiver design with only one waveform, the design of two receive waveforms. Then, the optimal transmit waveform for the linear modulator is derived by introducing the notion of the impropriety frequency function of a discrete-time random process and by performing a line search combined with an iterative algorithm. The optimal solution shows that both the periodic spectral correlation due to the cyclostationarity and the symmetric spectral correlation about the origin due to the impropriety are well exploited.

This study investigates the effects of the spatial elements of the mulit-purpose commercial complex on visitors' circulation pattern and wayfinding by employing method of space syntax, observation, and interview survey. Two commercial complexes were investigated; Techno-mart represented a vertical type and COEX mall rendered a horizontal one. Analysis of the spatial elements using space-syntax method provided a base line for comparing analyses by the two other methods. Analysis of the interview additionally survey identified the factors affecting wayfinding behavior and contributing satisfaction. The findings suggest that level of the effects of the spatial configuration on visitors' circulation pattern is greater in Techno-mart(vertically oriented) than COEX(horizontally). In COEX, for instance, specific route that connects sub-way station and cinema complex carries far more traffic than main route, even though the main route indicates higher degree of integration of spatial configuration. Similar with observation, the degree of integration is corresponding with the satisfaction and easiness of wayfinding behavior In COEX, specific place and feature seem to have more effects on visitors' wayfinding behavior and circulation pattern than the level of integration of spatial configuration.

Due to the development of technology, urbanization, industrialization, etd. at modern times, even the individual view of value has changed in variety. That means the change of each consumcer's life-style and even that of propensity to consume. In that regard, the modern, commercial space became to be increasingly included to specialization and complication. Such specialization and complication of the commercial space can be thought to be a positive response of enterprises to satisfy the needs or desire of consumers who become diversified. In this study, some new models in the method of the planning and designing of the S.I.P(Shop Identity Program). intended to research into as follows ; - As the background of the advent of the multi-used shopping complex, changes in consumer life-style and propensity to consume according to social and economical changes were intended to be studied through various statistical data literature. - For the study of the characteristics, constituent conditions, and planning operation of the future multi used shopping complex in the marketing aspect of enterprises, it was intended to study centered on the theory of consumer behavior and that of retail marketing. - In the process of the spatial design of the multi-used shopping complex, it was tried that a designing process to materialize a target of the discrimination and orderly arrangement of stores be progressed. In the process of materializing a target based on both corporate image and 'brand' image in designing.

As a result of rapid aging speed in our society, it is necessary to supply a lot of housing for older people in near future. When we think that high portion of residence in rental housing complex composed of small units is the elderly, the housing units in those apartments have to be designed for the physical, mental, social, and economical conditions of elderly people who lives in such a residential complex. Considering these living conditions of the elderly, this study proposes a remodeling prototype of a living unit for older people in rental housing complex. For the research of this topic, various characteristics of the elderly and the environmental requirements for them firstly have been analysed from the literature survey and the interviews with two residents living in a rental apartment. And the design considerations for each space of the housing unit such as entrance, living room, bed room, bath room, and so forth have been explored. Based on the design guidelines above, the remodeling plan of a housing unit for older people has been propose as a result of this study.

With a rapid expansion of the elderly population, there is a greater demand for the construction of senior complexes. However, due to a land price increase and insufficient financial resources, accommodating such a demand is challenging. Also, as aging progresses, many elderlies tend to be isolated from local community, because of deteriorating health. As a result, constructing senior complexes is becoming an important community project. The construction of senior complexes in Korea has been started since early 2000, so it is still in the beginning stage in Korea. However, in the case of Japan, they have more experience in building such buildings. Therefore, in this study, 49 senior complexes in Japan were analysed, and the following spatial characteristics were derived. 1. By classifying senior complexes largely into a complex type with similar facilities and a complex type with different facilities, 12 types were derived. Depending on the types of facilities, basic sharing rooms and selectively sharing rooms by need are suggested. 2. Depending on 4 characteristics, such as spatial composition, entrance type, circulation form, and complex facility type, 17 types of senior complexes were derived, and the characteristics of each type are presented.

The purpose of the research is to track the morphological transformation of apartment complex sites in Busan, especially focusing on building arrangement on apartment complex sites. Though there have been numerous studies regarding apartment housing, only few studies have been performed about the building arrangement. The arrangement has been poorly treated and not well disclosed as compared with other apartment-based research such as form of residential towers, floor plan, etc. The building arrangement is one of the most critical decisions at the early design stage and is affected by numerous social aspects such as building/zoning code, market demand, cultural preference, etc. Thus, the transformation of the arrangement may provide the hint for the change of socio-cultural demands of apartment housing. The research has been done on the existing 269 apartment complexes which have been built through 2016 in Busan. There are three categories set for analysis: relationship between buildings, relation between road and buildings, and the building arrangement along site perimeter. The result shows that significant change has occurred since 2000s; the arrangement has become diverse from three types to seven types. The early model of parallel or lattice types have been dominant until 2000, but the skewed one replaced the parallel or lattice types in Period V and Period VI, which is from 2001 through 2016.

The features of the cultural phenomenon, 'Hybrid Culture,' can be analyzed through the concept of 'Meme,' the cultural gene continuously evolves. The architectural meme also has an effect as the cultural symbol on a space. It can be the solution to the urban problems, lack of contextualization caused by reckless development. Therefore, this study aims to examine the characteristics of the sustainable and effective renewal space by applying the concept of Meme. Theoretical analysis, characteristics of expression, and case study are conducted to analyze the Meme features of the renewal space. Particularly, this study focuses on the Meme features appeared in the Zollverein Coal Mine Industrial Complex in German. The results obtained from this study is as written below. First, Meme renewal space is a design that can solve the contextual deficiency of architecture through the cultural renewal. Second, the true renewal space has the characteristics of meme space that organically changes as if an organism. Third, it is possible to conduct a detailed analysis on the organic characteristics according to the evolving phases-Mimesis, Memeplex, and Metameme. Fourth, the true meaning of sustainable renewal space is the Meme space encompasses the scope of urban. Lastly, the Meme space has a circulation system that each evolving phase, and new and old continuously exchange feedbacks.
