본 논문은 사용자가 감각형 인터페이스를 사용하여 가상공간의 지능적인 화단을 체험, 체감 할 수 있는 시스템(Garden Alive)을 제안한다. 제안된 시스템은 카메라, 조도, 습도 센서를 갖춘 현실공간의 화단과 상호작용에 사용되는 감각형 인터페이스, 진화모듈과 감정모듈을 갖춘 인공지능 모듈, 그리고 가상식물의 성장과 반응을 보여주는 Virtual Garden으로 구성된다. 감각형 인터페이스는 카메라로 사용자의 손동작을 인식하고, 조도센서로 광량을 확인하여, 습도센서로 물의 양을 측정한다. 이러한 정보를 바탕으로 인공지능 모듈은 식물의 진화 방향과 감정상태의 변화를 결정한다. Virtual Garden은 L-system을 기반으로 제작되어 가상식물들은 실제 식물들과 유사한 형태로 성장하도록 한다. 제안된 Garden Alive에서 화단의 식물들은 각각의 개체마다. 유전자를 가지고 있어 식물의 다양성을 볼 수 있고, 빛과 수분 등의 환경요인에 따른 적합도를 평가함으로써 세대를 거듭함에 따라 진화해가는 모습을 볼 수 있다. 마지막으로 단순히 자극에 반응하는 식물이 아닌 사용자와 상호작용에 따른 식물의 감정 변화를 통해 적절한 반응을 보이는 지능적인 식물을 구현하였다. 따라서 제안된 시스템은 오락과 교육을 위한 콘텐츠, 사용자에 따른 개별적 반응을 통해 심리적인 안정을 제공할 수 있는 콘텐츠 등으로 응용될 수 있다.

신경망은 입출력 관계가 명시적으로 표현되기 어려운 경우에 수집된 데이터를 이용하여 원래의 함수를 근사할 수 있느 특성이 있다. 최근에는 신경망의 모델링 성능을 향상시키기 위하여 여러개의 모듈을 기반으로 신경망을 구성하는 모듈형 신경망이 활발히 연구되고 있다. 본 논문에서는 린덴마이어 시스템(L-시스템)의 문법적 적용을 통하여 이러한 모듈형 신경망의 구조를 결정하는 방법을 제시하고자 한다. L-시스템은 본래 식물의 성장과정을 기술하기 위하여 제안된 방법인데, 본 논문에서는 신경망의 모듈형 구조가 L-시스템의 문법을 통하여 적절히 결정됨을 보인다.

The environmental characteristics, absorption rate of NO$_2$, physiological response, and quality of lettuces were examined in a semi-closed plant production system consisted of human and plant modules. Leaf lettuces were transplanted to 10-cm diameter pots at 4-to 5-leaf stage, and grown in a gas-fumigated plant module. Air containing NO$_2$was circulated 10 min-ON/ 20 min-OFF between the human and plant modules by a diaphragm. At 0.13, 0.30, and 0.45 $\mu$mol.mol$^{-1}$ NO$_2$, NO$_2$ decrements in the chamber during the 10 min were 0.040, 0.109, and 0.149 $\mu$mol.mol$^{-1}$ , respectively. The NO$_2$absorption rate of the plants was estimated to be 0.078 $\mu$mol.mol$^{-1}$ .m$^{-2}$ .min$^{-1}$ at 0.45 $\mu$mol.mol$^{-1}$ NO$_2$ was less than that of the control plant at 4th and 5th days, whereas the respiration rate was the same. The lettuce grown at 0.45 $\mu$mol.mol$^{-1}$ NO$_2$ had similar leaf length, leaf area, dry and fresh weights, and quality to that grown without NO$_2$.

The purpose of this research is to analyze the methods of the decorations using module plants in interior spaces. This research produced 18 types of the module plant decoration: considering the classifications of module plants(soil, hydroculture, moss), directions of module plants (up, side, down), assembling ways of module plants (horizontal, vertical). Applying these 18 types to the interior space decoration (floor stand, wall attach, ceiling hanging), 54 types were classified. After that, 150 cases of the decoration using module plants in interior spaces were collected and analyzed. In result, the cases were belong to 25 types of 54 types. The important types were the types to be able to decorate wide area of walls or ceilings without occupying floor area: SOIL-UP-VERTICAL, HYDROCULTURE-UP-VERTICAL, MOSS-SIDE-VERTICAL. These types were the decorations with function of bio-filter for air cleaning. Special types were SOIL-SIDE-HORIZONTAL, SOIL-SIDE-VERTICAL with soil developed not to pour and SOIL-DOWN-HORIZONTAL, SOIL-DOWN-VERTICAL with lucks not to pour soil. Plants will be used widely in interior design because of the awareness of eco-friendly design. The strength that module plants are portable, changable, able to exchange parts helps users to maintain plants in interior spaces. For designers, module plants are flexible materials in order to make variety of forms to adjust to interior spaces. The results of this research about methods of the decorations using module plants in interior spaces are useful to designers who want to design interior spaces eco-friendly and user-friendly.

The objective of this study was to analyze the effects on the growth of Sedum species by different soil in shallow green roof module system, and to find the best soil mixture. The experiment used a module system, 7cm soil depth, five types of soil mixture ratio, and it was carried out on 7th Hoar rooftop in December of 2010. The growth status of the plant showed the most superior of the P5C7P2V1, next P10C1P2V1 and P1P1V1, P1 and C1 showed very poor growth. This result showed that the soil mixture ratio (P5C7P2V1) in green roof module system with minimum management can contribute to the proliferation of rooftop greening in urban settings.

The purpose of this study was to evaluate temperature reduction and heat budget of extensive modular green roof planted with Sedum sarmentosum and Zoysia japonica. Plant height and green coverage were measured as plant growth. Temperature, net radiation and evapotranspiration of concrete surface, green roof surface, in-soil and bottom were measured from August 2 to August 3, 2012 (48 hours). On 3 P.M., August 3, 2012, when air temperature was the highest ($34.6^{\circ}C$), concrete surface temperature was highest ($57.5^{\circ}C$), followed by surface temperature of Sedum sarmentosum ($40.1^{\circ}C$) and Zoysia japonica ($38.3^{\circ}C$), which proved temperature reduction effect of green roof. Temperature reduction effect of green roof was also shown inside green roof soil, and bottom of green roof. It was found that Zoysia japonica was more effective in temperature reduction than Sedum sarmentosum. Compared with the case of concrete surface, the highest temperature of green roof surface was observed approximately 2 hours delayed. Plant species, temperature and soil moisture were found to have impact on surface temperature reduction. Plant species, air temperature, soil moisture and green roof surface temperature were found to have impact on temperature reduction in green roof bottom. As results of heat budget analysis, sensible heat was highest on concrete surface and was found to be reduced by green roof. Latent heat flux of Zoysia japonica was higher than that of Sedum sarmentosum, which implied that Zoysia japonica was more effective to improve thermal environment for green roof than Sedum sarmentosum.
