This study investigates and analyzed the psychological effect of existence or non-existence of cut-flowers decoration in the conference place by the presenting eight colors of decorations (white, pink, blue, orange, red, green, purple, and yellow) to the participants, 103 numbers of genders. The measurement of psychological condition was carried out and compared with an attention recovery scale, profile of mood states (POMS) and semantic differential (SD method). In addition, paired t-test, One way ANAVA and Pearson’s correlation analysis were used for the statistical analysis. As the result of investigation for the general awareness of cut-flower decoration, the most priority is its color tone and 57.3% of participants which is the highest portion answered that the amount of annual investment for cut-flower decoration is 20,000～99,000 Won. According to the result of comparison for three psychological indexes, the attention recovery scale was significantly higher in the area with cut-flower decoration than the area without it. In POMS, it showed the negative emotions, such as, tension-anxiety, depression, confusion was low while the positive emotion like vigor was significantly higher in the area with cut-flower decoration than the area without it. In addition, the participants could feel the pleasant, natural and clam significantly more in the conference place with cut-flower decoration than the area without it. The order of color preference of cut-flower was Green > White > Pink > Blue > Yellow > Purple > Orange > Red with significant difference. Also, as the result of investigation for the color sensibility of its tone of the cut-flower decoration in conference place with SD method, the participants could feel ‘comfortable’ and ‘calm’ the most with green, white and blue decoration while ‘strong’, ‘vibrant’, ‘uneasy’ of feeling was shown the most in red and orange decoration and ‘warm’, ‘fancy’ in yellow. Based on the result of this study, the workers can have positive psychological effects by having cut-flower decoration or using appropriate colors with cut-flower decoration in the uncomfortable area, such as, conference place.

This study is conducted with the questionnaire survey of 174 participants to investigate the psychological effect of workers with the indoor-garden in lounge of public building. The measurement of mental state was investigated and compared with loyalty, attention restoration, profile of mood states (POMS) and semantic differential method (SD Method) while statistical analysis was compared and analyzed with paired t-test, frequency analysis, cross correlation analysis, one-way analysis of variance, and Pearson’s correlation analysis. As the result of analysis of three psychological index, the rate of attention of restoration to the worker was significantly higher in the area where the indoor-garden is installed than the area with no indoor-garden (p≦0.001). Emotional examination showed less negative emotions, such as, the tension, depression, anger, exhaustion or confusion while more positive feeling was vitalized in the area where there is indoor-garden in the lounge than the place with no garden. In addition, as the result of comparison for the index of emotion by gender, negative emotions of men decrease but positive feeling increase more than the group of women in the area where there is indoor-garden in the lounge than the place with no garden. As the result of evaluating the emotion of pleasant, natural and relax with SD method, worker might feel them more in indoor-garden of lounge. Detailed items of plant does not seem to affect to the loyalty in the interest of indoor-garden to the workers, however, behavioral element, such as, feasible investment-cost, provides extremely positive effect (p≦.05). Based on this study, the cognizance of healing effect, attention restoration, profile of mood state (POMS) and emotional quotient by the existence of indoor-garden can be concluded that it will provide the positive effects to diffuse indoor-garden and promotion of emotional health for the staff. In addition, indoor-garden can be practically used to reduce the stress and provide the stability of the indoor-staff.

The purpose of this study was to evaluate the effect of essential oil on wound healing rate, an epithelial attachment and collagen density in wound induced rat. This study was a 2×3 factorial design. Factors were treatment period (4 day and 8 day) and treatment type [saline (0.9% NaCl), tyrothricin, mixture of tea-tree, rosemary and melissa oil]. The samples were 24 rats with wound and randomly assigned to six groups of four rats per group. The dependent variables such as a wound healing rate, an epithelial attachment and a collagen density were measured. Dependent variables were statistically significant difference by the two treatment periods and the three treatment types (p<.001). There were not statistically significant interactions between treatment periods and treatment type in all dependent variables (p>.05). These findings will be provide bases to develope effective interventions for patients who have wound to manage their wound.

This study analyzed the questionnaire of 279 participants which counted 26 cases out of total 305 participants. It is organized to find out the influence of indoor-plants for green interior of psychological effect, general awareness and the color or shape of indoor-plants in dining/living area to the preference of consumers and emotional image. 74.6% of participants had the experience of purchasing the indoor-plants for green interior. As the result of general awareness of green interior, the most important factor when the green interior was organized was the shape of plants and the most selected possible amount of investment to the installation was less than 100,000 won which is not high enough. As the result of investigation on participant’s awareness of effect of indoor-plant, 99.3% of participants which was the highest portion answered ‘Indoor-plants improve the psychological stability’ from the selection of five kinds of indoor-plant’s effects. More than 50% of participants showed high interests to the green interior in dining/living area as they selected ‘Preferred’. Decoration of cut-flower and eruption are preferred as the design of dining area. The preference order of 5 types of colors for green interior was white> green> pink> yellow> red and showed significant difference. As the result of investigation on color sensitivity of green-interior area with Standard Deviation method, white and green stimulus group highly shows the emotion of “Clam” and “Comfortable”. In addition, red and pink stimulus group feels hard the emotion, “Fancy”. Cut flower decoration was highly preferred when living area is decorated with 76.6%. Also, there was significant difference in the shapes of green interior in living area with the order of horizontal> round>vertical. According to the result of study on emotional difference with green interior of living area with Standard Deviation, horizontal way has “Calm”, “Comfortable” while vertical provides “Heavy” and “Strong”. This study tries to provide the useful and positive possibility of design direction and improvement of consumption of indoor green-interior by understanding of psychological effect and awareness of indoor-plan.

This study was carried out to investigate the formaldehyde (FA) filtration pattern of additional media for indoor biofilter system. Dry pellet type activated carbon (PAC), activated clay (ACL), zeolite, diatomite, pumice and loess ceramic ball were tested. In the case of dry filter media, formaldehyde purification efficiency was the most excellent with activated clay and then was good with the activated carbon, diatomite, zeolite, and pumice order. PAC and ACL decreased the FA concentration with exponential pattern resulted from dynamic balance between emission and purification. Zeolite, diatomite, pumice, and loess ceramic ball showed high filtration rate at initial time and then increased FA concentration result from breakthrough. PAC, zeolite and diatomite could be recommended as additional filter media for biofilter system considering FA filtration and breakthrough characteristics. FA filtration and breakthrough characteristics were improved with wet media except PAC and ACL. In particular, purification performance improvement and breakthrough mitigation were higher in pumice and loess ceramic balls. PAC+ZEO mixing showed the most high purification performance and breakthrough mitigation in all mixing methods. Thus mixture of PAC with zeolite and vertical mixing could be recommended as additional filter media to improve the FA purification ability and pressure drop with indoor air biofilter system.
