This study aims to measure the emotional effects of pet plants, which have become popular in recent years. A questionnaire regarding perceptions of these indoor plants was administered to 78 university students. Thirty of these students took care of two species of pet plants for 90 days, and the emotional effects of this exercise were determined based on the type of words used in their daily records. The questionnaire results showed that the general recognition of emotional effects was low, though awareness of the term "pet plants" was high. However, after gardening for 90 days, participants began to consider their pet plants friends or family members, noting feelings of affection and sympathy in their daily writeups. These participants also experienced positive changes in their emotional well-being, including feelings of joy, hope, relaxation, confidence, and accomplishment. This study argues that pet plants can have positive effects on emotional stability and suggests that their adoption would be beneficial to humanity at large.

Indoor gardens tailored to suit individual tastes offer a place to enjoy plants and to relax to city dwellers to relieve stress from city life. However, there are technical issues to build such indoor gardens. To offer solutions to technical issues, this study aims to analyze development phases of indoor garden-related technologies by studying available patents in detail. Also, the study aims to understand current status and future direction of technologies by examining technological trends for introduction of indoor gardens. Brainstorming method was used to understand technology trends and as a result, two groups were identified for technical features of indoor gardens: indoor greening technology and rest area for users. An analysis on selected patents showed that the number of patents increased until 2010 and declined gradually afterwards. Korea ranked the highest in the number of patents grant followed by USA, Japan and Europe. Similar order was observed with the number of patents granted by nationality of applicants. The number of patents granted by nationality was the highest for Korean nationals. For indoor greening technologies, patents related to structure from 2007 were mostly concentrated in the areas of irrigation control and environment control for plants and vegetation. For rest area related technologies, patent related to structure showed a repetitive pattern of increasing and decreasing, but overall, on downtrend. For further development and dissemination of indoor gardening technology, more R&D work is needed with focus on environmental control technology for designing suitable environment for both human and plant.

현대사회에서 실내원예는 크게 벽면녹화나 가정 미니정원과 같은 복합설치 실내원예와 꽃꽂이, 테라리움, 실내 미니식물 재배와 같은 식물 위주 분야로 크게 나눌 수 있다. 이러한 실내원예에서 테라리움은 가장 일반인이 접근하기 쉽지만, 한국에서의 테라리움은 미적 감각이 우선 시 되었기 때문에 테라리움의 본래 목적인 밀폐공간에서 식물을 지속 가능하게 성장하고자 하는 취지가 상실되어버렸다. 또한 밀폐된 공간안에 식물을 식재하기 위해서는 식물의 미니화가 필요하다. 이러한 식재식물의 제한성 때문에 다육식물, 선인장, 이끼 등에 이용 가능 식물이 국한되어 있다. 이와 같은 문제점들을 극복하기 위해 본 연구에서는 다육식물 브론즈(X Graptosedum, Bronze)를 이용하여 테라리움 식재식물의 건전주화, 테라리움 식재를 위한 미니식물의 다양성, 미니식물의 대량생산을 통한 가격절감 등 3가지 문제점을 개선하였다. 특히 조직배양 된 다육식물을 조직배양 용기의 교체 및 식물체의 조성을 새롭게 하여 비보리움으로 발전시켰다. 본 논문에서는 현재 테라리움 문제점을 개선하고자, 새로운 실내원예 분야인 비보리움을 창안함으로 보다 일반인이 쉽게 접근할 수 있는 새로운 실내원예 분야를 창안하였다고 할 수 있다. 현대사회와 같은 1인 가구의 증가 및 팬데믹(Pandemic) 시대에서의 실내활동 증가로 인한 새로운 실내 원예 분야의 소개와 참여는 심리적 안정에도 도움이 될 수 있다고 판단된다.

Background and objective: This study investigated plant type and color preference and conducted a psychological assessment for gardening activities of firefighters in a high-risk occupational group. Methods: A survey was conducted on 117 firefighters aged 39.01±9.17 in Sunchang in March 2020 to examine their preferences in plant type and color and conduct a psychological assessment of firefighters on gardening activities. Results: For plant experience and awareness, plant-related event showed the highest score, followed by plant preference tendency and plant growing experience. The level of plant gardening activities was higher among older age and higher job position. As a result of examining the quality of life according to the demographic characteristic with WHOQOL-BREF (World Health Organization Quality of Life Assessment Instrument), it was found that the quality of life was higher among the 20s-30s than 50s, firefighter position than fire lieutenant or higher, those with higher average monthly income, and the singles group than married (p < .05). The administration group showed lower scores than the fire suppression group working in the field, showing statistical significance. Most firefighters showed high preference for herbal plants among the 12 types of flowering plants, in the order of Rosmarinus officinalis>Lavandula spp.>Mentha piperita, Calendula officinalis. Pelargonium spp. was preferred the least out of the flowering plants, Lycopersicon esculentum was preferred the most out of 12 types of vegetable plants, while Angelica acutiloba was preferred the least statistical significance. For the preference of plant colors, yellow was the most preferred color, followed by white, blue, orange, red, and green, showing statistical significance. For the psychological survey responses of emotion words toward 6 plants colors, it was found that 'bright' was the emotion felt most strongly by the white, yellow, and orange groups, 'calm' and 'comfortable' by the green and blue groups, and 'fancy' by the red group. Conclusion: The effect of agro-healing programs can be increased by using mostly yellow plants when creating indoor healing gardens at the workplaces of fire officials in a high-risk occupational group, and using herbal plants and Lycopersicon esculentum in the gardens for agro-healing activities.

In the modern era, the elementary schools in the Republic of Korea are advanced with the competitive world. Thus advancement in technology, and other factors in the elementary schools are releases some kind of particulate matter (PM), which causes deleterious effects on school students health, academic program, growth and development. The school students are susceptible to PM particularly, PM₁₀ and PM_2.5. Based on this hazardous effect of PM on school students we conducted the research on the elementary schools class rooms by introducing vertical gardening system to get the schools "ever green". The main aim of this study is to investigate the environmental factors in the educational effect program in the class rooms and indoor air quality changes. For the educational effect, the 4th operation program was applied to 2 schools for 2 hours once a month from September to December 2019. Each school conducted a survey on satisfaction, plant friendliness, and environmental sensibilities, targeting classes that participated in the green school program and those who did not. The environmental effects were monitored by installing indoor air quality facility in the program participating classes and the non-participating classes. From November 2019 to December 2019, three factors were measured: PM10, PM2.5, and humidity. The results were analyzed by T-test using the SPSS 24.0 software program. As a result of the analysis, student's overall satisfaction with the program and their intention to re-engage were high in terms of educational effect. It was also found to be effective in emotional, educational, social, and physical aspects. In particular, it was found that there was a statistically significant effect on improving plant friendliness in terms of plant friendliness and environmental sensitivity. In terms of environmental effects, it was found that there was a significant difference between the program-applied and non-programmed classes in PM10, PM2.5, and humidity. Through this study, it was confirmed that the plant education program using vertical gardens is effective in both the educational effect and the improvement of indoor air quality in the classroom. In conclusion, vertical gardening system in the elementary schools should implement for the beneficial of young generation development and back bone to the nation.

The result of a small electrostatic precipitator which is in order to decrease indoor air pollution for optimal efficiency was shown as follows. Although the closer distance between the discharge electrode and dust collecting electrode shows the better throughput efficiency by forming strong electrostatic Field, it does not have profound impact in case of optimal dust collecting area. G.P(gas passage) which is the distance from dust collecting electrode to dust collecting electrode is a crucial factor to decide dust collecting efficiency. The narrower distance of G.P shows the better throughput efficiency whereas it decreases when the distance is too narrow since sparks ensue by increasing the capacity of electrostatic charging system 5 mm regards as optimal efficiency in this experiment. Although the higher voltage shows the higher dust collecting efficiency overall, the experiment was not able to keep performing since the sparks which decrease dust collecting efficiency ensue over 40 kV. The efficient and safe voltage state is considered 3.6 kV in this experiment. The most crucial factor for dust collecting efficiency of an electrostatic precipitator which is in order to decrease indoor air pollution is applied voltage. In addition, optimal raw gas flow rate(2.4 m/sec) is more important factor than the excessive increase of dust collecting area.

The purpose of this study was to find out awareness of the environment-friendly planning elements for residential unit space among practitioners. The respondents in this questionnaire survey were 140 practitioners in architecture and interior design field. The major findings of this study were as follows; most of the respondents were aware of the impact of indoor built environment on residents' wellness. In addition, the survey respondents viewed that the factors for planning environment-friendly high-rise apartments were represented by gardening and energy-saving while their perception on the concept excluded comprehensive components affecting residents' life quality. Over 50% of respondents had an experience of applying environment-friendly planning elements in their works, and high frequency appeared on the general planning elements which had been applied special awareness as pro-environmental features. The respondents considered environment-friendly planning elements as important. Specially, space planning and system were considered more likely important in interior design field. In application of environment-friendly planning elements, cost, lack of consumers' awareness of and underdevelopment of environment-friendly materials were of concern. Therefore, the consumer's cognition needs to be improved for wide application about environment-friendly planning element, and then consumers are willing to pay additional construction cost of environment-friendly apartments. At the same time, the current practice that housing developers pass the additional cost on to residents needs to be changed. Then, the quality of life in high-rise residential settings can be improved. More importantly, the exchange and development of the reliable information on environment-friendly planning elements need to be made, and technical support and long-term policy for the development are required. This research showed current status of knowledge and practice in sustainable planning of unit apartment and proved basic information for future direction.
