In order to research the effects that indoor plants of apartments in Seoul have on the happiness index, we tried to analyze relationships between indoor plants which are nearest to the residents and happiness which is the final goal of the residents, and for this 200 residents who live in apartments in the Seoul city area were sampled. This study was based on the precedent studies of the facts that horticultural therapy and function of plants had already proven the affirmative roles of plants to people. The results were as follows. Residents reported that they were happiest when the plants were blooming(57%), when the plants were sprouting(33%), when repotting(2%), when distributing(2%) and others(7%). The residents exposed to indoor plants were in direction proportion to the happiness index within 1hour. Happiness indexes of the residents who cared for potted plants were by themselves was 67.90, when family members cared for the plants, 65.09, and when others cared, it was 64.79. The preference of indoor plants and the happiness index according to the scale of interior gardens were in direct proportion. Lastly, the happiness index of residents according to the number of potted plants, was in direct proportion: the more potted plants, the greater the happiness index.

The final goal of this research is to develop a botanical biofiltration system, which combines green interior, biofiltering, and automatic irrigation, which can purify indoor air pollutants according to indoor space and the size of biofilter. The biofilter used in this experiment was designed as an integral form of water metering pump, water tank, blower, humidifier, and multi-level planting space in order to be more suitable for indoor space utilization. This study was performed to compare indoor air quality between the space adjacent to a botanical biofilter and the space away from the biofilter (control) without generation of artificial indoor air pollutants, and to evaluate plant growth depending on multiple floors within the biofilter. Each concentration of indoor air pollutants such as TVOCs, monoxide, and dioxide in the space treated with the biofilter was lower than that of control. Dracaena sanderiana ‘Vitoria’ and Epipremnum aureum ‘N Joy’ also showed normal growth responses regardless of multiple floors within the biofilter. Hence, it was confirmed that the wall-typed botanical biofilter suitable for indoor plants was effective for indoor air purification.

죽절초는 높은 광도 보다는 낮은 광도에서 생육이 건전하게 유지되고 광합성률이 높은 것으로 나타났다. 그러므로 죽절초가 최적으로 생육할 수 있는 조건은 전광의 약 70%정도로 낮은 광도인 실내환경에서 잘 적응할 것으로 추정되어 실내 조경 식물소재로 도입한다면 좋은 관상수가 될 수 있음을 알 수 있었다. 식물 생장의 중요 조건 중 하나인 기공전도도 또한 70% 비음처리구에서 가장 높게 나타나 실내 조경식물로 죽절초가 생육하는 경우에 실내의 낮은 광도에서도 원활한 기공개폐가 이루어져서 실내공기 오염도를 낮추는데 중요한 역할을 할 수 있음을 보여주었다.

This study analyzes the current status and management characteristics of plants introduced into indoor spaces to identify strategies for developing green elementary schools. Indoor plants are predominantly potted and primarily introduced into shared spaces, including entrances and hallways, rather than classrooms. Although the positive effects of indoor plants have been acknowledged, there is also an awareness of negative sentiments, including the difficulties in managing them. Although some level of plant maintenance is carried out, there are recognized challenges, such as budget allocation, designation of responsible personnel, and availability of management information. To ensure proper maintenance, concerns like budget support, assignment of duties, and increased interest need to be addressed. Compared to other staff, teachers express a greater need for plants to be introduced, which should be evaluated in terms of maintenance, environmental purification, and safety. In future restructuring projects to create spaces for learning, relaxation, and other activities by introducing plants indoors, the following should be considered: selection of plants suitable for environmental characteristics; establishment of maintenance plans including the budget; and expert support. Moreover, strategies to approach plant maintenance as an educational activity through student participation programs and the development of educational materials should be considered.

In order to investigate the effects of foliage plants on the changes of indoor thermal- and hygro- environments, experiments were carried out in two rooms with similar physical factors. Changes of indoor environmental parameters according to the existence of plants, their arrangement methods, and the existence of wrapseal for protecting the loss of water from the pot soil were measured during certain periods in winter and summer season, using Pachira aquatica which is widely used as indoor plant and has higher photosynthetic and traspiration rate than other foliage plants. The data suggested that the existence of plants didn't affect directly on the indoor thermal environment, while relative humidity increased about 3~5%, regardless of season, by putting plants which had volume equivalent to 2.4% of room volume. In summer, there was no difference in increasing effect of relative humidity between parallel arrangement with window and spread arrangement in the room, but in winter the former arrangement was more effective than the later.

Air pollution due to the fine dust level updating every day, and the problem of indoor air pollution due to ventilation difficulties and indoor discharge pollutants is also serious. In order to improve the indoor air quality, the air purification effect using the plants is prominent. In this study was started to investigated the living environment of modern people, the risk of indoor air pollution and the improvement function of plants, and to activate plant application. The purpose of this study is to analyze the main functions and design status of domestic and overseas plant - related applications, and to understand the actual use of modern plant applications and to help them learn more convenient plant - related knowledge. Therefore, this paper attempted to establish a basis for suggesting a new plant application by conducting a survey on the health effects of indoor air pollution and user awareness of plant - related applications. The results and contents of the study are as follows. First, as a theoretical review, indoor air pollution is more dangerous to modern people who have a high proportion of indoor living time and adversely affects their health. In order to solve such a problem, it has been shown that air conditioning and stress reduction can be effectively achieved by placing plants in the indoor space. Second, the analysis of the previous study shows the risk of indoor air pollution and its adverse effects on health. In addition, I have been able to find some researches related to the improvement of the indoor air by using the air purifying plants, and I can see the improvement of the user's behavior through the development or improvement of the application. Third, as a result of the survey on the status of domestic and overseas plant application, the main function of the application having high installation number was watering notification, provision of basic information of plants, and most of the functions were plant discerment through cameras. Fourth, most of the survey respondents have either raised or raised plants. Those who have little experience with plant applications have also shown positive feedback in the future on the use of plant-related applications. In addition, due to social problems such as air pollution, air purification using plants and functional plants showed high interest. Based on these results, we propose the need for a multi-functional plant application that can improve the indoor air pollution and facilitate the provision of information related to it.

This study investigated the changes of indoor thermal environment by Ardisia species planted in indoor space. Three Ardisia species (Ardisia japonica, Ardisia crenata and Ardisia pusilla) were used in this study and differences of temperature and relative humidity were ascertained in an empty chamber with and without plants. In high temperatures over $24^{\circ}C$, Ardisia species cooled down chamber more as compared to the control without plants, but there were no significant differences among Ardisia species. Ardisia crenata showed high relative humidity of $57.3{\pm}3.1%$ during most of the day time and $60.8{\pm}2.5%$ at low temperatures. However, Ardisia japonica and Ardisia pusilla showed $54.7{\pm}1.18%$ and $52.5{\pm}2.4%$, respectively, on the average, and they maintained comfortable relative humidity during most of the day time. When the setting temperature was decreased from 28 to $26^{\circ}C$, Ardisia species showed 7.5~13.6 times greater cooling efficiency as compared to the control without plants, and at low temperatures the chamber without plants showed higher themal energy than the chamber with plants. Ardisia species were effective on cooling down the temperature at high temperatures and they showed a tendency to maintain proper temperatures at low temperatures.
