The purpose of this study is to provide a practical guide for the actual conditions and the preference of student housing in a regional university. The data are collected through questionnaire surveys from the students of a regional university. 265 samples are collected, and are analyzed by using SPSS-PC. The results are as follows: 1) The actual conditions of student housing Most residents of student housing(76.3%) come from the Capital region. Most of student housing are located at 30 minute distance from the school. Most of house style are Offistel as one room style. Most of housing size are within 10 minute distance from the school. Most of house style are Offistel as one room style. Most of housing size are within 10py, and two people reside in one unit. The average hours of staying at the student housing are over 10 hours. The most inconvenient factor is the lack of soundproofing in the current student housing. 2) The preference of student housing The most preferred location is in the walking distance from the school, and the apartment is the most preferred housing style. The most preferred installation of inside is internet connection. When choosing student housing, students prefer the distance from the school as the most important factor. Most female students reside with a roommate within 10 py of housing size, cook for themselves, and consider rent and maintenance fee as the decision factors in choosing housing. The most preferred style of house is apartment, and they prefer to install basic furniture and kitchen system inside of housing. As students go up to higher grade, they prefer the apartment, and prefer to cook for themselves. More fresh men reside with a roommate compared to other grades.

The purpose of this study is to scrutinize the change of Korean dwelling space terms, and confirm the value of literature as data for a study on dwelling space terms. The terms, which describe the dwelling space, were selected in 63 Korean literature. The terms about rooms, working spaces, space for physiology and hygienic, and storage spaces, were analyzed. The terms about rooms were classified by a constituent unit of traditional housing, location, size, function, and so on. Among them, the number of terms about function had increased more and more. These terms were changed by housing size, housing form, structure of house and household, family size, and so on. It was confirmed that literatures have utility values for a study on change of dwelling space terms. In next study, it is required to analyze the meaning and usage of Korean dwelling space terms, and to compare terms in floorplans with terms in literature.

The study verified the extinguishing performance of the low pressure water-mist system, which is used to extinguish fire at domestic wooden architecture, through a fire test. Made of inflammable materials, a wooden house is vulnerable to fire, and the size of fire may vary from the early stage in case of arson. With the discharging pressure of 8 bar and the flow rate of 35 lpm, the low pressure water-mist nozzle used in the experiment has considerable discharging amount compared to other water-mist nozzles. The extinguishing performance was tested based on the size of fire and architecture. Test results demonstrated that the extinguishing performance was not affected by the size of a house, but decreased significantly when the size of fire was above unit 1. Taking into account that the environment of actual wooden cultural properties is more vulnerable than that of the experiment model, sufficient investigation on extinguishing performance is required to apply the water-mist extinguishing system to wooden architecture.

The movement of animals is one of the primary factors that influence the variation of livestock emissions. This study evaluated the relationship between animal activity and three major emissions, PM₁₀, PM_2.5, and ammonia gas, in weaning, growing, and fattening pig houses through continuous monitoring of the animal activity. The movement score of animals was quantified by the developed image analysis algorithm using 10-second video clips taken in the pig houses. The calculated movement scores were validated by comparison with six activity levels graded by an expert group. A comparison between PMs measurement and the movement scores demonstrated that an increase of the PMs concentrations was obviously followed by increased movement scores, for example, when feeding started. The PM₁₀ concentrations were more affected by the animal activity compared to the PM_2.5 concentrations, which were related to the inflow of external PM_2.5 due to ventilation. The PM₁₀ concentrations in the fattening house were 1.3 times higher than those in the weaning house because of the size of pigs while weaning pigs were more active and moved frequently compared to fattening pigs showing 2.45 times higher movement scores. The results also indicated that indoor ammonia concentration was not significantly influenced by animal activity. This study is significant in the sense that it could provide realistic emission factors of pig farms considering animal's daily activity levels if further monitoring is carried out continuously.

A series of laboratory experiments carried out to investigate the particle separation efficiency and flotation characteristics using $CO_2$ bubbles. The primary objective of this study was to find out the feasibility of $CO_2$ bubbles as an applicable unit of flotation process in tap-water and wastewater treatment plant. The fundamental measurements were conducted to characterize the $CO_2$ bubble from the physical viewpoint in water including bubble size distribution and rising velocity under various operational conditions. In addition, the removal efficiency of solid was experimented using the lab scale plant applied $CO_2$ bubbles, namely the dissolved carbon dioxide flotation (DCF) process. The DCF process using carbon dioxide bubble, which is an advantage as the decrease and the reuse of Green-House gas, can be a promising technology as an water treatment process. On the other hand, the further research to decrease the bubble size distribution of $CO_2$ is required to enhance the particle separation efficiency.
