This paper aims to clarify physical characteristic of empty house and vacant floor in historic district on Cheongju. First, most empty houses are the timbered houses of 1 story, and it will be built before the 1969. And the building of a vacant floor has a common non-residential buildings of 4 stories, and there are many buildings of RC structure built in the 1980s. Second, when the situation of an empty house and a vacant floor was seen, there was most the second floor only by the number of room, but when seen from the ratio of the whole number of rooms, there were most the third floor and the fourth floor. Third, when the situation of a vacant floor and a vacant room was seen from use, there were most store, shop and office. Relevance with this as close as reduction of the population in the center of Cheongju is seen. Moreover, the grope of a method which can utilize this is required.

Recently, many urban traditional houses have been replaced by villas and apartments for the inconvenience of lifestyle. The aim of this study is to survey the present distribution condition, research the extension and alteration, focused on Korean urban traditional houses in Cheongju which is the old city in an inland area, and inquire into the behavior patterns of an aged living alone livelihood and a large household. As a result, in the typical 'ㄱ' types of central inland houses, all the rear and side parts are nearly extended except facades facing court, while the detached houses for an aged living alones and tenants have enlarged rooms, kitchen and 'Daecheong' within the existing wooden framework. We could grasp the enlargement of room, 'Daecheong', corridor, and storage in the layout of the existing house. There are so many alterations such as the stand-up kitchen and a water closet. A new extension on an old house was intensely built for tenants.

Among the protected horticulture facilities in Korea, 99.2% are pipe-framed green houses and most of them are structurally vulnerable single-span type green houses. This study examined peak external pressure coefficient for the roof surface of a green house group composed of single-span and a multiple-span green houses. According to the results of the experiment, the distribution of peak external pressure coefficient was around 30% higher in the single-span greenhouse than in the multi-span ones. The external pressure coefficient for the roof surface of the vinyl house group was, in all of the three vinyl houses, was around 20%-30% higher than that for single-span greenhouses.

This study aims to examine and classify plane types of Hanok at Haengbok village, analyze changes, area distribution and space structures of space components and sort plane types and their characteristics. Plane types were divided into four; living room, kitchen, dining room, etc. These plane types were labelled as LK type, L+K type, L+DK type and LDK type. LK type and L+K type were mainly found at single-wing house and made of living room and kitchen centered space structure, but substantially they were designed to ensure guest room, room and living room. Therefore, hanok built at Haengbok village were designed to combine the functions of residential function and lodging. Plane type was preferred to be used for double functions of residence and lodging. On the other side, L+DK type and LDK type were mainly found in house with several wings and they were designed centering around living room for family space. In addition entrance was placed to simplify entry from the outside and each room and guest room were arranged to be accessed from living room. It means that the functions of house focused on residence rather than lodging and all rooms had the structure to be used as residential space in case of emergency.

The PFT (PerFluorocarbon Tracergas Technique) is of advantage to field surveys for evaluating the ventilation condition, due to its simplicity and convenience. On the other hand, it requires researchers to make some additional considerations that include uncertainties, such as the substance concentration distribution in indoor air, representativeness of a sampler, deviation of emission sources, and analysis error. In this study, the PFT and $CO_2$ tracer gas methods were applied simultaneously, to evaluate the accuracy of PFT on six ventilation conditions in the three-storied detached house. The air exchange and the outdoor air introduction a between and into zones were measured. As the results, deviations of PFT concentration distributions were observed at a sufficiently low level for an accurate determination for a house where the interior height was large, and there were relatively many partition walls. However, when a uniform airflow appeared in the indoor air, it was also validated that the indoor air would be exhausted without sufficient mixing, and consequently the measurement error of the PFT would be large.

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.

The purpose of this research is to analyze the characteristics of flow rate distribution in hot-water piping networks in the apartment building. A 14-story apartment house was selected as a sample building and analyzed numerically by Hardy-Cross method. Two different piping networks, one has three vertical zones and the other of a single zone with automatic balancing valves, were compared. Some of research results are as follows; As the temperature of supply hot-water increases, the flow rate of it does by buoyancy effect, but this effect is not found in the piping network with automatic balancing valves. Non-uniformity in hot-water flow distributions to all stories in the piping system of single vertical zone can be completely reformed by the installation of either manually operated or automatic balancing valves in every story.

The purpose of this study was; 1) to describe consumer preferences for wood~framed housing; 2) to determine factors which affect the preferences for housing environments in wood-framed housing by demographic, current housing, and wood-framed housing-related characteristics; and 3) to identify differences in preferred wood-framed housing related characteristics by demographic and current housing characteristics. From the visitors to a model wood-framed house in Seoul, Korea, 296 persons willing to live in a wood-framed house were selected as the sample for the study. Data were collected using a self-administered survey and analyzed by frequency distribution, factor analysis, chi-square test, t-test, and one-way analysis of variance procedures. The results of the study Indicated that among seven factors based on 32 housing characteristics, Factor 2 - "floor plan and Interior environment" was the major variable which showed significant difference by selected demographic characteristics. Regarding the differences in wood-framed housing related characteristics by demographic characteristics, age, gender, education, and family life cycle showed group differences. Also, housing type was the major current housing characteristic to provide significant group difference in preferred wood-framed housing characteristics.

The purpose of this study was to investigate the present conditions of thermal environment in small-size apartments. The research methods used were measuring of environmental elements and personal self-administration for the residents' thermal comfort responses. The house subjected were 25 peung apartments facing southeast and southwest directions. The results of this study were summarized as follow ; The indoor temperature and humidity of houses subjected were 25.0∼27.3℃, 37.1∼42.5%. Compared with the distribution of indoor temperature and globe temperature of houses subjected, those of southeast house were more stable. And in the residents' thermal sensation responses, the residents of southeast houses checked more often neutral zone. Therefore the thermal environment of southeast houses were more comfortable condition than southwest houses.
