The study is about variations in Carbonyl compounds concentration within apartment buildings according to pre-residence and residence. We consecutively investigated indoor air pollutants in 120 households in 6 cities at pre-residence and residence. Carbonyl compounds were collected using the 2,4-DNPH cartridge and were analyzed using HPLC. The carbonyls concentration of indoor air in the new apartments before occupation measured formadlehyde($76.0\;{\mu}g/m^3$), acetone($85.9\;{\mu}g/m^3$), acetaldehyde($13.8\;{\mu}g/m^3$). The carbonyls concentration of indoor air in the new apartments after occupation measured formadlehyde($233.1\;{\mu}g/m^3$), acetone($128.9\;{\mu}g/m^3$), acetaldehyde($29.8\;{\mu}g/m^3$), respectively. As a result, the mean concentration of carbonyl compounds within the pre-occupancy stage was lower than those of residence.

This study was performed to compare dietary behaviors based on residence types of female college students. Self reports on dietary behavior and one-day dietary records were obtained from 227 female college students using anonymous questionnaires. The mean age of the subjects was $20.4{\pm}1.43$, and the height and weight were $162.5{\pm}4.8cm$ and $52.3{\pm}7.9kg$, respectively, The dietary behavior of female college students was inadequate, showing indifference to dietary balance, irregularity of meals, skipping breakfast, and high experience of drinking. One-day dietary records were obtained from 24k recall methods also showed a high number registering skipped meal status ($55.3\%$) and less diverse food intake (DVS, 12.5; DDS, 3.93). The students in self boarding residence were especially more likely not to eat properly and their dietary behaviors were found to be significantly poor. In the case of home residence, food intake frequency scores for milk and dairy products, fruits, and fishes were significantly higher, however the students in self boarding residences showed high food intake frequency scores in salted food, retort food, canned food, and especially instant ramyun. Therefore, more attention needs to be given to them to recognize the problems in their own dietary behaviors and more practical nutritional supports, like developing a menu for breakfast in college cafeterias, would be helpful to improve their dietary choices.

The purpose of this study was to identify the factors of university residence hall foodservice quality which has correlations with subjective QOL (quality of life) of target customers. A total of 176 questionnaires from students of 4 universities in Daegu, Gyeongbuk area were used for the analysis. The male students using residence hall foodservices were highly satisfied with 'clean appearances of employees' ($4.86{\pm}1.25$) and 'clean facilities' ($4.79{\pm}1.26$), while the degree of satisfaction with 'convenient facilities' ($4.50{\pm}1.20$) showed the highest score with female students. Ranking analysis using Spearman's ${\rho}$ revealed that there were significant correlations between students' satisfactions with the dimensions of 'foods and kindness of employees', 'hygiene', 'nutrition', and 'convenience' and their QOL, even though physical QOL of female students showed no significant correlation with satisfaction towards residence hall foodservices. As a conclusion, there should be efforts to improve the QOL of target customers through foodservice quality management.

The purpose of this study is to develop an evaluation system for integrative comfort values of Hanok residence. For this study, a mock-up located in Yongin, Gyeonggi province built by an ongoing governmental research project has been chosen. Then, SSN (Smart Sensor Network) has been utilized for monitoring quantitative factors in the environment and detailed face-to-face surveys have been performed for analyzing qualitative comfort indexes from residents in the experimental settings. Then, this study employs a combined evaluation system using AHP (Analytic Hierarchy Process) established for estimating overall DIC (Degree of Integrative Comfort) of the Hanok residence. As a result, the evaluation system could verify the total comfort indexes of Hanok residence and suggest converged methodologies for establishing value assessment system for traditional residential facilities. The method of DIC suggested in this paper would be examined with current residents in a built mock-up to see its applicability as a comprehensive evaluation model, and it is expected that collected year-round comfort data from the facility would provide more practical information towards future strategies for the Hanok residence.

A tendency of active exchanges of newly-generated culture and mind following with the world globalization has been leading totally new concept of social level, its life style and spending habit. According to these social movements, people's way of thinking has been shifted from we-centered to I-centered, which generate (cause) individualism. The tendency of putting much weight on individuality prevailed in the society grows the social awareness on individual's needs and tastes and ultimately lead overall movement of longing for single life style. The rate for singles also has been dramatically increased these days, and expects reach 30 percents of overall popularity in 2010. Therefore, various new concepts of residences for singles have been introduced recently, such as an office apartment, condominium and serviced residents, which combines concepts of both a hotel and an apartment. In this thesis, six examples of newly-styled residence for singles would be researched in every aspect, such as its service, facilities and so on. Although the fact of that overall service quality of new type residence now is well constructed and performed is derived from this research, I expect to contribute more various and advanced service quality into new social movement and new type of residences for single life, and finally provide satisfactory life style for singles.

The human scale of the interior space of a korean traditional residence is normally user-friendly. And this aspect is reinterpreted and implemented in the modern structure. While our conscious awareness has become greatly westernized through the east-west exchanges, the interior of the traditional Korean residence has always reflected the people and their daily lives of the time. In this study, an attempt has been made to identify the aesthetic characteristics of the inner space elements through the analysis of visual perception inside a Korean traditional upper class residence, kangreung Sunkyojang, designated as the 5th Cultural Information Material with regards to the inherent philosophy and human scale that influenced the emotions of the Korean people. The different parts of the interior space of Anchae, and the Symmetrical of Formal, Balance of the walls give a sense of calmness, and the ornaments are used to give gaiety. The ceiling of Yeolwhadang hall give an energetic feeling and pillare are used to enhance spaciousness. In Whalejeong, by making use of similar and continuous lines, the light and darkness was controlled and the link with nature has been emphasized. Different decorations used reflect scholarly spirit.

This study was conducted to examine dietary behaviors according to residence status and ethnicity of university students in Yanbian, China. For the subjects, 334 university students (Male=141, Female=193) answered a questionnaire about perception of weight control, dietary patterns, health habits, residence status, and ethnicity. Perception of weight, meal frequency, favorite kind of food, meal finishing time, skipping breakfast, type of breakfast, snack frequency, late-night snack frequency, exercise frequency, regular life, and sleeping time were all significantly associated with residence status. Motivation of weight control, meal frequency, regularity of meal time, meal volume, favorite kind of food, exercise time, and regular life were all significantly associated with ethnicity. University students who lived with their parents perceived their weight more properly, exhibited a more positive dietary pattern, and lived a more regular life than those students who lived in a dormitory with their friends. Chinese students exhibited a more regular dietary pattern and lived a more regular life than the Korean-Chinese students. As a result, both environmental and inherent factors are related with the dietary behaviors of university students in Yanbian, China. These data could be used to help university students in Yanbian, China attain a healthy diet.

The radioactive experiments are carried out for diagnosis of a variety of industrial processes in terms of the operation condition and the efficiency by measuring the residence time distribution. However, it is not easy to interpret the residence time distribution using the conventional methods when the flow rate is not constant and a number of processes are coupled in a complicated manner. In these cases, they can be analyzed by describing the system with mathematical models that can be defined with the state-space equations. In this paper, the residence time distribution of sludge was measured with a radiotracer, $^{46}Sc-EDTA$, in the digester of which the flow rate varies with time. The digester was assumed as a linear time variant system since the flow rate changed during the experiment and the operation efficiency of the digester was calculated by applying the state-spae equations.

A seismic isolation system is one of the most effective control devices used for mitigating the structural responses due to earthquake loads. This system is generally used as a type of base isolation system for low- and mid-rise building structures. If the base isolation technique is applied to high-rise buildings, a lot of problems may be induced such as the movement of isolation bearings during severe wind loads, the stability problem of bearings under large compression forces. Therefore, a mid-story isolation system was proposed for seismic protection of high-rise buildings. Residence-commerce complex buildings in Korea have vertical irregularity because shear wall type and frame type structures are vertically connected. This problem can be also solved by the mid-story isolation system. An effective analytical method using super elements and substructures was proposed in this study. This method was used to investigate control performance of mid-story isolation system for residence-commerce complex buildings subjected to seismic loads. Based on numerical analyses, it was shown that the mid-story isolation system can effectively reduce seismic responses of residence-commerce complex tall buildings.

The purpose of this study is to analyze the stress variation according to Hitler's residence using EEG data. Hitler's residence, one of the most monumental buildings, is designed as a grand and overbearing space, giving the visitor a sense of psychological pressure when moving from a high space to low space. Based on the above background, this paper constructs Hitler's residence using virtual reality and measure the changes of the beta waves which are known to be related with stress when the floor level moves from high to low space in Hitler's residence built in virtual space. The results of the experiment are as follows; when moving from high to low space, the subjects' stress was high and at the same time brain waves variation was increased greatly due to changes in space.
