  • This research was aimed at finding clues of improving residential quality of the Urbanistic Housing which was introduced for the small household of 1-2 residents. It was the laws on communal amenity in multi-family housing that this research concentrated on. Looking into the multi-family housing standards for small household of Korea, Japan and UK, Japanese One-room housing Ordinance of Tokyo-do laid stress on avoiding conflict among residents and getting people mixed together. And UK's concentrated on every individual rooms inside HMO and suggested certain level of qualified life through the careful standards. On the other hand, Korea's just suggested minimum housing with unit households and nearly no amenity except for parking lots. There should be more than a physical space with some area which satisfies basic physiological needs in a residence. To become a quality residence filled with relationship, it is necessary that Urbanistic Housing are also required to provide communal amenities, not as much as regular housing for regular household but much more than Quasi-housing, the minimum residence. And it should be ensured by the legal system to make it more effective.

  • This study was carried out to know bending process property of bentwood by treatment methods such as microwave and ammonia solution treatment. Bentwood processing was operated on bending-jig form with 60mm and 100mm radius of curvature (ROC). The species was used to Korean red pine (Pinus densiflora). No significant difference was shown in bentwood processing method on ROC. In treatment method, ammonia solution treatment for bentwood was better in dimensional stability and working ability than that of microwave treatment. However, bentwood stress was reduced with ammonia solution treatment. Color of bentwood surface appearance has a dark tendency in ammonia solution treatment. But it seems to beautiful effect of apparent annual ring is rising esthetically by ammonia solution treatment. To utilize wood as a exterior material for living amenity, it has to be closely examined from various angles including surface property, degree of swelling and shrinkage, drying state, retaining strength, durability, safety, and insect damage.

  • A pedestrian environment provides improved walking conditions and facilities for most pedestrians. However, the walking conditions for women with strollers are poor. The purpose of this study was to provide information on the walking environment planning for women with strollers in an urban housing area through analyse of walking characteristics, patterns of going out, and the psychology of them. This study surveyed 208 women who pushed a baby n a stroller in Gyeongsan. The analysis consisted of calculation of the frequencies, the mean, t-test, and ${\chi}^2$ test. The survey results revealed that, first, the women had their own favorite places in the housing area, and usually went out during the afternoon as various aims. When they went out, they felt stress both psychologically and physically, and they thought that they were weak at walking. Second, the safety and the convenience factors of walking environment were important conditions that make the women to go out often. Third, the environment that have not the accessibility, the amenity, and the diversity also restricted the women from going out with the stroller. As a result, they did mot use the stroller and tended to use their cars to go out. However, when the diversity of the environment is added to walking environment, women invreased their social interactions.

  • EEG has been used to measure the emotion of amenity and discomfort in the interior space. EEG is limited to the experiment, because it is a equipment of contact type. However, Vibraimage can measure the emotion with a web camera. Because Vibraimage is a equipment of non-contact type, it is more suitable for the interior space than EEG. Therefor, it tries to find a correlation variable between EEG and Vibraimage to measure the human emotions. In this study, it were analyzed correlation of EEG and vibraimage due to variation of loudness 60[dB], 90[dB] and rosemary, jasmine scents. Check the health status of subjects who were selected 3 male students, and the period of this experiment was about months. The condition of the environmental test room was in temperature 25[$^{\circ}C$], relative humidity 50[RH%], air current speed 0.02[m/s] and illuminance 1000[lux]. It were analyzed correlation of twenty-three index of EEG(absolute ${\theta}$, relative ${\theta}$, absolute $S{\alpha}$, relative $S{\alpha}$, absolute ${\alpha}$, relative ${\alpha}$, absolute ${\beta}$, relative ${\beta}$, absolute $\gamma$, relative $\gamma$, absolute $F{\alpha}$, relative $F{\alpha}$, absolute SMR, relative SMR, $SMR/{\theta}$, $SMR+M{\beta}/{\theta}$, absolute $H{\beta}$, relative $H{\beta}$, $H{\beta}/{\alpha}$, absolute $M{\beta}$, relative $M{\beta}$, SEF50, ASEF50) and ten index of Vibraimage(Aggression, Stress, Tension/Anxiety, Suspect, Balance, Charm, Energy, Self regulation, Inhibition, Neuroticism). As a result, I was found that relative ${\gamma}$ index of EEG and neuroticism index of Vibraimage have a high correlation as (${\pm}$).414 and (${\pm}$).424.
