Purpose: Residents in deteriorated residential areas of Seoul have suffered from parking shortage problem. Since it is almost impossible to supply new parking, it is critical to find a way to efficiently utilize existing parking spaces. This study proposes utilizing unused parking spaces in apartment complexes so that residents in multi-unit or multi-family houses can share those parking spaces. Method: Spatial scope of this research is limited to multiplex-clustered neighborhood and apartment complex in Seoul. To identify the nature of parking problem, we reviewed current parking situations in residential areas and policies from the Seoul Metropolitan Government. To understand the amount of parking spaces required to solve parking shortages in multiplex-clustered neighborhoods, this study analyzed car ownership per household and available parking spaces in old residential areas. Then we were able to apprehend the amount of parking spaces that could be used for residents in aged multiplex-clustered areas. Result: Our analysis shows a great potential to utilize surplus parking spaces from apartment complexes for solving parking problems in multiplex-clustered neighborhoods.

This study was conducted to investigate the living environment of semi-basement housing units in multi-household houses. It analyzed measurements of temperature and humidity obtained from the housing units. For this study, temperature and humidity sensors were installed in 10 semi-basement housing units to measure interior temperature and humidity for 13 months. A survey was conducted to get information about the occurrence of dew condensation and mildew and to investigate residents' satisfaction level with the residential environment. According to the result, all the housing units under study had dew condensation and mildew. The average summer temperature of the 10 housing units was $27.84^{\circ}C$, and average humidity was 64.91%RH, while the average winter temperature was $20.6^{\circ}C$, and the average humidity was 40.12%RH. Depending on the condition of each housing unit, deviation was big. Residents' average level of satisfaction with the living condition was 2.03 which shows a low satisfaction (on a scale of 1-5 with 5 being completely satisfied.).

This study provides a descriptive and analytical account of major aspects of urban development and transformation of housing types of Italian Firenze from the 13th century to the 19th century. It is a typo-morphological depiction of urban spatial structure of the extraordinary city, Firenze, the center of Italian Renaissance. And this study has proceeded on the assumption that the evolving form of the urban structure and housing types cannot be understood without reference to the larger context of political, economic, and social life. Based on these backgrounds, the purpose of this study is threefold: to provide a comprehensive discussion of general characteristics of urban spatial structure of Firenze, and to explain the process of formation of working-class neighborhoods by constructing new city wall in later 13th century, and to discuss transformation of housing types of the working-class neighborhood with understanding the mechanism of existence of housing in the newly formed residential neighborhoods. The development of residential neighborhoods was pursued by 'planned' manner through forming square-shaped blocks, and characterized by the subdivision of larger properties into standardized building lots for the construction of houses. On the bases of documentary evidences, several ecclesiastical institutions are identified as the agents of a distinctive type of development. While the institutions did the major role for developing lands, the construction of houses was done by small scale construction agents with moderate amount of properties. The major housing type of working-class neighborhoods of Firenze has been the 'casa a schiera' characterized by the form of narrow front and long depth. The type was generalized by the newly formed middle and working-class of Firenze which grew their body very rapidly, Even though the type assumed very uniform in its fen there were many variations. And through passing time, the casa a schiera developed to be multi-family housing, and the level of variation became deepen. Eventually, transformation of housing type of Firenze was ended by appearance of the 'casa in linea', which was very similar to modern apartment in its spatial organization.

The purpose of this study is to find out understand the resident's subjective responses to physical indoor environment. The questionnaire survey was carried out to measure form Jan. 8th to Feb. 2th in 1996, the typical external climate of winter in Korea. The subjects were four hundred and eleven housewives, living in apartments of RC structure I Ilsan apartment complex. As the result, residents usual ventilate once or twice a day by opening outward windows for about ten minutes. Unpleasant smell producted by cooking and wet garbage made most of them negatively respond to kitchen's air quality. regression analysis of relativeness between sense of air freshness smell, dust and comfort revealed that sense of comfort was the most highly related with the extent of bad smell. Housing factors such as size of apartments and ventilating, smoking and gas usage had significant effects on indoor air quality and the subjective responses in winter. Therefore it is especially important to consider air pollution problem from the beginning stage when planning small apartments. It is required that the government of environment has to emphasize the importance of ventilation to residents, and makes an effort to establish the design criteria on indoor air quality in house.

Building parts of Multi-Family Houses are consisted of several building material assembly. Therefore, after selecting building materials with test result of emission intensity and their feature, composed building materials are made equally with actual construction methods, and experimented emission intensity. 7 days after experiment, formaldehyde emission intensity appeared low in an order of Tile Wall, Wood Flooring, Wallpaper, Reum Flooring, Silk Wallpaper, and 20 days after experiment, TVOC emission intensity appeared low in an order of Tile Wall, Reum Flooring, Silk Wallpaper, Wood Flooring, Wallpaper. There was a clear difference in TVOC emission intensity according to kind of building materials. Composed building materials that weight per unit area is big and omission intensity is high, they effect continuously to indoor air because decrement is small.

'Sohawjang' is the first apartment house built in Busan the modern period, 1944. 'Sohawjang' needs to be apprised its value as an very important object of study with architectural and dwelling historic meaning because multi-family houses built in Japanese Rule Era that now exist in Korea are very rare. Thus, this study attempted to leave records to archive by conducting face to face interviews and surveying on 'Sohawjang' which is seriously in danger of extinction and its original form damage as the first step. Especially, around Korea's Liberation, this study tried to extract transformation characteristics of residential space and cultural differences appeared on differences of occupants having different nationality. Through these results, this study attempted to examine the era of apartment house and transformation characteristics and values of modern dwelling historic dimension according to changes of users appeared in Busan modern period. Through this study, it offers basic data about introduction and transition processes of an apartment house in Korea. It has an meaning of suggestion reference data for original form preservations or regenerations.

In response to the economic depression, the demand for fixed rent income has increased according to the easing construction regulations. it caused indiscriminated investment to stakeholders. This leads to oversupply in the multi-family Housing market and increases unsold housing and vacancy rates except specific area such as Gangnam-gu.In order to solve this issue, although studies on the optimization price of apartment houses has been conducted, the study is insufficient regarding on residential officetel. Therefore, the objective is to suggest a basic study on optimal price estimation model development by using probabilistic forecasting method in planning phase. To achieve the objective, first, variables are defined such as expenses, financial costs, income, etc. Second, causal loop diagram is suggested. Third, basic optimization prices estimation model is developed. In the future, this study can be used as one of decision making tools in planning phase of officetel development projects.

Purpose: Urban heat island and Heat wave raise urban temperature and create damage of human life. Growing up as quantitative supply to solve shortage of housing, Urban residential area in Korea have a low rate of nature surface and heavily population makes temperature rise. Most houses in the declined residential area are multi-family rental housing and have many factors congesting housing environment such as narrow in-between space, outdoor staircases, walls and semi-basement floor, which make thermal environment getting worse. Most of the residents in this area are small tenants vulnerable to climate change adaptation, This damage is expected to be even greater. This study focus on multiple dwelling in urban residential area prone to temperature rise and draw temperature adaption method that can apply to multiple dwelling.

This study analyses the relationships between the residents'personality and the residential types, and between the sense of crowding and the residential types. For this purpose, this study surveys two hundred ninety three residents in their thirties and forties, residing in Seoul. We find that there are differences in the personality traits and also differences in the sense of crowding according to residential types such as high-rise/low-rise apartments, high-class private residence, multi-family houses. And these differences are due to the differences of inner and outer residential environment satisfaction. The lower a resident's inner environment satisfaction is, the higher is his/her sense of crowding. And low environment satisfaction and high sense of crowding appears to account for one's depression and anxiety. Conversely, the higher environment satisfaction is and the lower the sense of crowding is, the higher is his/her responsibility. Finally, this study tries to examine how each personality trait changes according to the habitancy duration. We find that residents having a 3-5 year habitancy record are more anxious and depressed than those who have been living more than 7 years in the same residence.

During the winter season, when electricity usage increases rapidly every year, fires are frequent due to short circuits in aging electrical facilities in multi-use facilities such as traditional markets and jjimjilbangs, apartments, and multi-family houses. Most of the causes of such fires are caused by excessive loads applied to aging wires, causing the wire covering to melt and being transferred to surrounding ignition materials. In this study, we implement a system that measures the overload and overheating of the wire through a composite sensor, detects the toxic gas generated there, and logs it to the server through the gateway. Based on this, we will develop a platform that can predict, alarm and block electric fires in real time through big data analysis, and a simulator that can simulate fire occurrence experiments.
