Wall-embedded ventilators, which are commonly used for ventilation of buildings, greatly damage the aesthetics of the building due to pollutants such as dust and grease sticking to the fan and gaps of the ventilator as the period of use increases. For this aesthetic reason, it is often installed in a place that is not easily visible to people, and if the ventilation fan is not properly arranged and installed, it is difficult to maintain indoor air in an optimal state. In this study, the effect of the arrangement of ventilators on indoor ventilation performance was investigated. Comparisons were made between the case where three ventilators were concentrated and the case where they were spaced apart at regular intervals. It was found that the ventilation performance was different depending on the location where the ventilators were installed.

대나무를 이용하여 화훼장식품을 개발하고 그 작품을 전시하였다. 대나무의 길고 굵은 가지를 교차시켜 현대적 디자인을 하고 그 사이에 식물을 고정시켜 작 품성을 높였다. 대나무 선단부의 긴 가지와 잎을 밀집 시켜 숲을 만들고 그 속에 안정감 있는 분화류를 배 치하였다. 대나무를 세로로 잘라 기둥을 만들고 그 선 단부에 대나무 용기를 부착시켜 식물을 심었다. 대나무 기둥의 움직임에 의한 리듬감을 표현하였다. 대나무의 잔가지들을 서로 엮어 면을 만들고 그 면에 식물을 매 달아 벽장식 작품을 구성하였다.

This study was conducted to know the visual preference and emotional change for the cut-flower decoration at public indoor space by using vertical, horizontal, and round type which are generally used. The investigation was done with 173 participants of National Institute of Horticultural and Herbal Science in 3 indoor areas designed with cut-flower decoration and 1 area of public place without it, respectively. Psychological evaluation was analyzed with the visual preference of cut flower shape and Semantic Differential method. In addition, the general awareness, loyalty and importance for cut-flower decoration were investigated. Statistical analysis was carried out with paired t-test, one-way ANOVA, cross correlation analysis, and analysis of frequency. As the result of evaluating the emotion of subjects with Semantic Differential, the feeling of comfort, nature and calm were significantly high in the public indoor space with cut-flower decoration. When we surveyed the feeling for the 3 type of cut-flower decoration with 14 pairs of emotional vocabulary, the participants felt ‘tranquil’ and ‘comfortable’ in the public indoor space with horizontal and round shaped decoration while they felt ‘strong’ and ‘anxious’ in the space with vertical shaped decoration. The preference of decoration forms was significantly high with round > horizontal > vertical type in order and vertical shape was highly preferred in twenties and sixties groups compared to other types significantly. In conclusion, we could recommend that round type decoration can be used in indoor place where comfort and calm are required and vertical form will be appropriate for challenging and vibrant twenties and depressed sixties with ageing. This customized cut-flower decoration will improve the environment quality of employment.
