The purpose of this study is to estimate the housing demands in order to address a suitable housing policy for a metropolitan city of Daegu in South Korea. Although the population of Daegu declines, a number of households increase since a number of people per households decrease. Currently a household with four people is a main housing type, however it is expected that a household with one or two increase. In 2017, a household with one will be dominant. Estimating housing sizes and their demand, the households below $60\;m^2$ gradually decline while those over $85\;m^2$ is expected to rise. Nevertheless, the demands for the house below $60\;m^2$ in its size increase at 39.2 per cent. Currently a house with $60\;m^2$ is being constructed. In particular, that of $85\;m^2$ gradually increases. The current trends may result in the widening gaps between the household demand and supply of Daegu. Therefore, it is recommended that relevant local authorities and developers should consider providing various house sizes by taking the current housing demand of Daegu into account.

The habitual rooms and other structures related to everyday life are almost always grouped around the courtyard and together make up a house. There are many kinds of variety in types of courtyard houses depending on location, composition, allocation and relationship with inner space of the house. Every type of courtyard house accumulates many factors, which are social and economic circumstances, weather and geographical conditions. They are still well harmonized with life style and weather conditions in each area and basic unit of city organization. A courtyard can be shown as a place for everyday conversation like a community. Everyday space is the connective tissue that binds daily lives together, amorphous and so persuasive that it is difficult even to perceive. In spite of its ubiquity, everyday space is nearly invisible in the professional discourses of the city, like everyday life. Therefore Courtyards are special places that are outside yet almost inside, open to the sky, - a microcosm which gives relief to the inner rooms, gives the inhabitants a sense of ease and calm, and the feeling that they have their own piece of sky to use and protect them. This research will explore a variety of space use and dwelling types through courtyards based on field research and design projects.

As the needs of housing for the elderly has increased, many researches have been carried out and some housing projects for the elderly including nursing home began to be provided. Most researches have focused on the development of housing type or space layout and only several ones on interior design. The interior design in house influences physically or psychologically on the elderly who lives in. Also, the subject of them which examined the needs or preference for housing for the elderly were the middle-aged, not the aged. The purpose of the study was to examine the preferred characteristics of interior design in residential space by the elderly. The structured interview with 120 old persons who lived in Busan was carried out using by a questionnaire and 3D images. The elderly answered about the preferred interior style, color, lighting and interior finishes of each room in house, such as living room, master bedroom, kitchen, and bathroom. On the basis of the findings, the characteristics of interior design of each room in house which the elderly preferred were presented. In general, they preferred the mixed interior style with tradition and modem.

The "sharing economy" describes a type of business built on the sharing of resources - allowing customers to access goods when needed. While sharing goods has always been a common practice among friends, family, and neighbors, in recent years, the concept of sharing has moved from a community practice into a profitable business model. This study explores gaps between customers' actual usages and current policies on accommodation sharing by analyzing what needs to be done for the better establishment of sharing economy in society. The purpose of this study is to investigate perceptions of accommodation sharing by analyzing reviews and negative aspects that help resolve complaints and improve better services through policy establishment. This study investigates key attributes that influence business performance to improve citizens' decision-making for the usage of accommodation sharing. This study applies qualitative research by collecting demand- and supply-side reviews from selected registered accommodations using a random sampling procedure. This study finds that guests prefer entire house sharing with instrumental attributes related to properties. Entire house sharing of multiple dwellings shows business impacts in terms of high occupancy rate on the platform, while there are policy concerns with entire house sharing. The results provide policy and managerial implications by suggesting proper policies and considering relationships with citizens.

Data-based analysis methods have become used more for estimating or predicting housing prices, and neural network models and decision trees in the field of big data are also widely used more and more. Neural network models are often evaluated to be superior to existing statistical models in terms of estimation or prediction accuracy. However, there is ambiguity in determining the input feature of the input layer of the neural network model, that is, the type and number of input features, and decision trees are sometimes used to overcome these disadvantages. In this paper, we evaluate the existing methods of using decision trees and propose the method of using decision trees to prioritize input feature selection in neural network models. This can be a complementary or combined analysis method of the neural network model and decision tree, and the validity was confirmed by applying the proposed method to house price estimation. Through several comparisons, it has been summarized that the selection of appropriate input characteristics according to priority can increase the estimation power of the model.

The increase in the rearing intensity of pigs has caused deterioration in the pig house's internal environment such as temperature, humidity, ammonia gas, and so on. Traditionally, the widely used method to control the internal environment was through the manipulation of the ventilation system. However, the conventional ventilation system had a limitation to control the internal environment, prevent livestock disease, save energy, and reduce odor emission. To overcome this problem, the air-recirculated ventilation system was suggested. This system has a semi-closed loop ventilation type. For designing this system, it was essential to evaluate the ventilation rates considering the pressure loss of ducts. Therefore, in this study, pressure loss calculation and experiment were conducted for the quantitative ventilation design of a semi-closed loop system. The results of the experiment showed that the inlet through which external air flows should always be opened. In addition, it was also found that for the optimum design of the semi-closed loop ventilation system, it was appropriate to install a damper or a backflow prevention device rather than a ventilation fan.

Paiwha's Hanok Dormitory had composed of 23 dormitories rooms, management space, sanitary space, dining space, etc. In living rooms division, there are three types of rooms, and it's room was 4~5 pyung(坪) in size and using area per person was 1pyung. Besides all rooms were connected by a corridor. The structure was 5-ryang(樑) type without high column or with one high column. Looking at structure and the shape of the roof on the historic photos, it seems to be a lower roof slope than other traditional house because of reducing its weight. But its span between two columns was wider relatively.
