The purpose of this paper is to provide information on planting construction for healthy plant growth. To achieve this purpose, this study analyzed the planting type, planting density, withering rate, soil characteristics, and cambium electrical resistance (CER) of withered trees in an apartment complex with a high withering rate. The major plant groups examined consisted of native broad-leaved tree species (39.3%), native narrow-leaved tree species (24.2%), and native broad-leaved - exotic narrow-leaved tree species (16.4%). The planting density of the green area, where trees were planted from 0.0 to 0.3 trees per unit area, was measured as 98.4%. Withered trees were found in 19 of the 20 planted species, and the withering rate was 41.8% (610 withered/1,461 planted). Withering rates for tree species were measured as follows: Sophora japonica and Salix babylonica (100.0%), Magmolia denudata (84.3%), Lindera obtusiloba (74.7%), cornus kousa (69.3%), acer triflorum (69.2%), diospyros kaki (66.7%), Prunus yedoensis (62.8%), Acer palmatum (52.6%), Prunus armeniaca (51.1%), Chaenomeles sinensis (43.7%), Ginkgo biloba (40.9%), Zelkova serrata (31.0%), Cornus officinalis (28.6%), Taxus cuspidata (25.6%), Pinus densiflora (21.4%), Pinus parviflora (15.2%), Pinus strobus (14.6%), and Abies holophylla (10.3%). Soil chemical analyses for 18 samples revealed that as the withering rate increased, the following occurred: (a) the ratio of silt and clay in soil increased; (b) the soil pH, organic matter rate, nitrogen, available phosphorus, and cation exchange capacity (CEC) in samples were graded as "inadequate," based on the plant grading evaluation; and (c) the NaCl and cation exchange capacity were evaluated as "somewhat satisfactory." The measurement of CER for withering rate shows electrical resistance for higher withering rate are higher, which could predict that a tree will not grow well.

In general, the verification to prediction formula in a national road and the main street of a town has been used recklessly in Korea. Therefore we investigated the validity of an existing prediction formula (NIER(87, 99), TR-Noise, KLC(2002)) with correction relationship which was based on both the prediction formular from apartment complex in the field and height 1.5m from the surface level. On the results of measuring the noise level form an isolated distance, the noise level showed that it was 4.5~5.5dB(A) by reason of becoming 2 folder far from a source. From the distribution of noise level measured by the apartment floors, the measurement point (1st floor) was 58.7~71.4dB(A) at its lowest level and the middle floors (3, 5, 7 and 10) were the highest distribution of noise level. From the analysis results on the application validity to an existing prediction formular (NIER(87, 99), TR-Noise, KLC(2002)) in the height 1.5m, the correction coefficients were 0.95~0.96 and the measured values were reasonably close to the predicted values, indicating the validity and adequacy of the predicted models. KLC(2002) model was found accurate within 3dB(A) with 36 data out of the total 42 data, showing the most accuracy among the predict models. However, the developed models have to improve the accuracy with a various of factors.

The purpose of this study was to gather baseline data to be used for improving housing environments and developing welfare policies for low-income groups by identifying the similarities and differences in housing environmental conditions and in the usages of community welfare services between the dwellers of Da-Ka-Gu rental housing and those of permanent rental apartment. This multifaceted diagnosis currently being undertaken can be utilized through the lowincome housing planning and welfare policies as the basis for future policy formulation. Self-administered questionnaires and interviews were carried out by 212 dwellers in Da-Ka-Gu rental housing (104) and permanent rental apartments (108) in the city of Gwangju from July to October of 2010. The main findings are as follows: 1. The dwellers living in both Da-Ka-Gu rental housing and permanent rental apartments are satisfied with their housing environment. Specifically, a higher satisfaction with transportation and a lower satisfaction with neighbor's inter-relationships were evident. The dwellers of Da-Ka-Gu rental housing appear to be more satisfied with community spaces and housing management than those of the permanent rental apartments, whereas the latter appear to be less satisfied with the noise of the housing complex than the former. 2. Of the community welfare service programs, a higher usage is shown for meals service, free health screenings, home repair, and after-school learning programs among all residents in the two housing types. In particular, for the residents of Da-Ka-Gu rental housing, the children's education and parent education programs are more popular, whereas for those of the permanent rental apartments, the housekeeping services and health services utilization are highest.

This paper presents the results of a case study of a dispute for the damage of the right to sunshine between B and W Apartment Complex in the N city. Recently a number of disputes for the right to sunshine increase in urban areas because the residents' demand for pleasant residential environment is getting stronger. In particular, problems related to sunshine, which were not recognized during the construction, have come up to the surface over time as people's concern over residential environment is growing. According to a recent interpretation of the right to sunshine in urban areas, moreover, there have been a series of legal decisions starting that damage of the right to sunshine to neighboring apartments must be indemnified for even if the violating apartment was designed and constructed legitimately according to relevant construction laws applied when the building was constructed. Thus this study examined the effects and the scope of damage on the right to sunshine through a case study in order to provide basic materials necessary to rope with related civil affairs.

In this research, I finally came to a conclusion analyzing the connection among managing of each items in management expenses, the size of each complex and stories, and the term of using. (1) In the managing cost regarding to the management manner, although the managing cost of self-governing management is less imposed than the one of commission management, there is slight difference between those Costs. And it is more important to consider the effectiveness of management than to emphasize reduction of management cost. (2) The higher the stories, the higher the managing cost of elevator per the unit area. It Is caused by the fact that the father the distance of the elevator operating, the higher the electric charges. (3) The third of one of total management cost goes to pay the personnel expenses. So I found that the effective management of the expenses is available to reduce management cost. (4) The higher the stones, the lower the cost of personnel expenses including the cleaner cost. (5) The sum of costs assigned in repairment and management increases in proportion to the term of using. The costs assigned in special repairment and management are interacting to each other. (6) To reduce the management cost, we have to cut down the personnel in security guard that occupies one third of total management cost with application to the joint security system and operation of the self-governing guard. Through this process, it will be easy to accomplish the rationalization of contract with an outside order. Because the improvement of management service is not only the responsibility of owner but also the one of dwellers. And it Is imperative to realize the importance of cooperation and trust between the owner and dwellers. And the establishment of effective managing system which has convenience and rationality must be settled without delay.

The purpose of this study is to find out how to effectively utilize the public facilities site that is being used in the new town for the expansion of newly required public facilities, because it is difficult to carry out redevelopment projects in apartment complexes of 1st generation new town due to the rigidity of land use and macroeconomic conditions. This study examined the following three ways to effectively utilize existing public facilities sites for Pyeongchon new town. First, it suggested how to secure the parking lot by deciding multi-dimensional urban planning facility of public facilities such as parks and schools in superblock that lacks parking space of apartment complex. Second, it suggested a plan to accommodate the demands of public facilities required by increasing the building density of existing public buildings in commercial district as an example of the Anyang Tax Office. Lastly, it suggested a way to install additional functions required by users through the reorganization of the existing public facilities and some extensions by examining the Pyeongchon library.

A common form of construction for apartment buildings consists of walls and coupling elements. But, the structural behavior of coupling elements are very complex and affected by the properties of coupling elements. The objective of this study is to estimate the behavior of coupling elements in wall-dominant systems. For the purpose of this study, two wall-slab specimens and two wall-beam specimens were tested. The specimens with different reinforcement layouts were subjected to reversed cyclic loading, consistent with coupling action, with increasing imposed inelastic deformations. From the results of this study, 1) in coupling slabs, the stresses were not uniform across the width, 2) the effective width of coupling slabs was found smaller than that of predicted from previous studies, 3) diagonally reinforced coupling beam with slab showed larger ductility and more amount of energy dissipation to be attained compared with conventionally reinforced coupling beam.

This study aims to analyze the actual state, the satisfaction index, and the satisfaction factor of the residents in the apartment adopting thematic outdoor rest space design. This study also proposes the basic data for the standard of resident-centered rest space design, not designer-centered or fashion-followed design. The results are as follows : First, most residents use near by rest space, and more use occur during the evenings; 17 hr. ∼ 21 hr. Most of residents use the rest space with their children, partner, or family. Residents usually take walks and take a rests in the rest space. Most residents use the rest space quietly. Of the rest facilities in the outdoor rest space, benches are most used, walks and pergolas are more frequently used. But waterscape facilities are not particularly used. The satisfaction index of the outdoor rest space is generally low. However, the satisfaction index of the rest space and facilities type shows that the evaluation of rest facilities(e.g. benches) is high. The satisfaction index of the decoration shows that the evaluation for the color and design of facilities is high. In the satisfaction index of the physical environment, the item about the size of rest space is highly appreciated. In the mental satisfaction index of the rest space, the item about whole atmosphere is highly appreciated. Of the factors affecting the general satisfaction index with outdoor rest space, the factor of physical environment is the most important independent-variable. Physical environment and facilities are more important influential factors than the atmosphere of outdoor rest space. In the future, the practical study searching for the preferences of the residents and the activation of use should be preceded.

This study aims to analyse the relationship between the sense of community and resident online participation. To solve a variety of social problems in localities, both resident participation and the sense of community have been getting more important. Online voting is a project that is being implemented by the city of Seoul to expand the participation of residents. We surveyed residents living in the apartment complex in Seoul that was participating in with the pilot program for online voting. The empirical analysis shows the sense of community was, indeed, positively related to resident online participation. In particular, shared emotional connection, a component of the sense of community, was the most important factor for the resident online participation.

This research explains a new process in architecture frameworks. A complete analysis on implementation of the specific frameworks can be conducted by a special system. Moreover, the system can be installed anywhere, and it produces a unique result, which is customized based on the contents of architectural designs by users. Before using the system, an architect should think about the design and the process of constructing frameworks because a computer sometimes computes misleading results although the architect describes architectural structures, which the designer wants. If the architect inputs the same process into the computer, and the result of frameworks changes, it is not a proper architectural design. Hence, a tool, which precisely treats data, is needed. Therefore, when constructing the proper architecture, a new paradigm of architecture should be used to distinguish the issues of discussion by using various data. Also, based on this information, an apartment housing complex design, related to possible parameters, which can be expressed by combining various fusion tables and geocloud, and architectural designs, is proposed.
