모델 하우스나 분양 홍보관 같은 가건물은 건물홍보라는 역할이 끝나면 철거되거나 폐건물로 전락한다. 철거하면서 발생하는 건설 폐기물들은 환경문제에 영향을 줄 수 있다. 또 COVID-19 로 인해 비대면 만남도 추구하고 있는 현재, VR 을 활용한 연구가 이루어질 필요가 있다. 본 연구는 VR 을 사용해 가상공간에서 모델하우스를 제작하면서 앞서 말한 문제들을 해결할 수 있다. 이를 통해 이 플랫폼으로 현 문제를 해결하고 더 환경문제 해결에 기여할 것으로 기대한다.

The occurrence of insect pests of Lycium chinense was monitored at 4 organic farms that was cultivated with environment-friendly management at Cheongyang, Chungnam from May, 2012 to September, 2014. Total 4 orders and 18 species occurred in the L. chinense. Among them, 4 major pests and Lepidopteran and Hemipteran insect pests were investigated the occurrence pattern. During the budding, the population density of Myzus persicae was very high in late-May and early-June, and the injury by Lema decempunctata was increased from mid-June. The injuries by Henosepilachna vigintioctomaculata and Hedma lycia sp. were continued throughout the growing season. From the fruit held in late-July, hemipteran insects including Plautia stali and Halyomorpba balys were sucking the fruit, and their injury to L. chinense were gradually increased. In the case of Eriophys macrodonis densities to increase gradually from early July. The population density of E. macrodonis in 2014 was rapidly increased more than 5 times compared with 2012 and 2013. It was supposed that the initial control of mites or the removing of over-wintering density in the past year might be neglected. However, there is a need to more review the factors for the mass occurs.

Host plants of the Henosepilachna vigintioctomaculata are known as Solanaceae plants such as potato, tomato, eggplant and Lycium chinense. Henosepilachna vigintioctomaculata (Motschulsky) cause continuous damage from early June to mid-August in leaves of L. chinense under environmental-friendly management in Cheongyang, Chungnam. The developmental period of egg and larva of H. vigintioctomaculata were investigated. H. vigintioctomaculata were reared on L. chinense at several temperatures, for example, 15, 20, 25 and 30°C in the laboratory. In addition, the control effect of 5 eco-friendly agricultural materials were examined. As results, hatching rate is the highest to 91% at 25°C. Egg periods were 10.8, 7.7, 5.1 and 3.7 days at each tested temperature, respectively. And the total developmental periods from egg to adult were 42.7, 26.3, 18.4 and 19.4 days at each tested temperature, respectively. Otherwise, their eclosion rates from pupa to adult were showed 58%, 77%, 85%, 65% at each tested temperature, respectively. As a result of the control effect, both adults and larvae of H. vigintioctomaculata were shown a high mortality to mixture with extract of Sophora flavescens, Chenopodium ambrosioides and Melia azedarach. Additional, larvae is shown high mortality to extract of Azadirachta indica and Cymbopogon nardus. Thus H. vigintioctomaculata might be controled by using plant extract of eco-friendly agricultural materials in due season.
