  • 본 연구는 자원식물 종자의 유용성을 증대시키는 방법의 하나로 쑥부쟁이속 6종(가새쑥부쟁이, 눈개쑥부쟁이, 벌개미취, 참취, 해국, 쑥부쟁이) 새싹채소의 최적 생산방법을 개발하고자 수행되었다. 적정 발아조건 구명은 온도(15, 20, 25, $30^{\circ}C$) 및 광조건을 달리하여 종자를 파종한 다음 발아율 조사를 실시하였다. 이후 길이생장 기간은 온도(15, 20, 25, $30^{\circ}C$)를 달리하여 암조건에서 10일간 진행하였다. 적정 녹화기간을 알아보기 위하여 최적의 발아조건과 길이생장 기간 동안 재배한 유묘를 0-3일간 광조건에서 재배하였다. 저장환경 및 기간을 알아보기 위해 최적조건에서 재배한 새싹 채소를 통기구가 있는 용기와 밀폐 용기에 각각 넣은 다음 $4^{\circ}C$$10^{\circ}C$에서 저장하였다. 연구의 결과, 종자는 발아율 조사를 통해 12일 이내에 50% 이상 발아하는 것을 선발하였다. 길이생장은 $20-25^{\circ}C$에서 생육이 우수하였고 최적의 재배기간은 7-9일로 구명되었다. 녹화기간이 길어질수록 길이생장은 지체되었으나, 하배축의 부피생장 및 떡잎의 생육이 왕성해지는 경향을 보였다. 여러 가지 요인을 고려하였을 때, 2일간의 녹화처리가 가장 좋을 것으로 생각되었다. 저장성 실험은 $4^{\circ}C$에서 저장한 밀폐 용기에서 저장성이 좋았으며 부패는 환기에 의해 방지되었으나, 수분함량이 감소하였다. 모든 새싹채소는 $4^{\circ}C$에서 3-6일간 신선도를 유지하였으며, 특히 눈개쑥부쟁이와 쑥부쟁이는 높은 저장성을 가져 $10^{\circ}C$에서도 3일 이상 저장이 가능하였다.

  • Recently, in addition to greening of roof and artificial soil, Rootproofing to prevent damage to the waterproof layer and structures by roots is recognized as an important task. Therefore, various related products and construction methods have been developed and applied in the field. However, in the case of synthetic polymer-based sheets most commonly used in domestic construction sites, Most are produced using 100% new materials that are not suitable for green trends such as resource conservation and environmental protection. Therefore, in this study, we developed TPO sheet using recycled material, which is a technology that can secure eco-friendliness by utilizing recycled resources. As a result of the evaluation of tensile performance of the TPO sheet according to the recycled material content, The tensile strength of the specimens with the recycled content of 50 ~ 70% was the highest, The elongation rate of the specimen with the recycled content of 30 ~ 40% was the best.

  • 도시 내 부족한 녹지공간을 확보하기 위하여, 기존 건물의 옥상 등 인공지반에서의 녹화가 점차 확대되어 가고 있으나 인공지반 대부분을 차지하고 있는 옥상의 경우 건물에 미치는 하중과 강우 및 관수에 관한 문제를 비롯하여 식물의 성장도 원활해야 한다는 점을 주의해야 한다. 현재 많이 사용되는 인공토양의 경우 원석을 수입하여 가공 생산하는 것으로, 앞으로 인공지반 녹화가 활성화될시 수입으로 인한 비용 등의 문제로 새로운 대체물질이 필요하다고 판단된다. 본 연구에서는 기존 녹화소재의 단점인 하중과 설치 후 유지 관리를 보완하고자 친환경 대체재료로서 폐목재칩과 폐지 슬러리를 이용한 식생기반재를 개발하고 그 제조조건에 대해 검토해보았다. 본 실험은 폐목재칩과 폐지슬러리의 혼합비와 비료의 주입농도를 달리하여 식생기반재를 제조하고 잔디와 보리를 식생기반재당 1 g씩 파종하여 성장률을 분석하는 것으로 진행되었다. 폐목재칩과 폐지 슬러리는 0.9 : 0.1~0.5 : 0.5의 비율로 혼합되었으며, 그 결과 혼합비율이 0.6 : 0.4 일 때 잔디는 약 1.5배, 보리는 약 1.9배 높은 성장률을 보였다. 또한 비료의 농도가 1%일 때 제조된 식생기반재에서 비료가 첨가되지 않았을 때보다 약 1.3~1.5배 높은 성장률을 보였다. 식생기반재의 pH는 7.1~8.8로 약알칼리성을 보였으며 주입된 비료의 농도가 높을수록, 폐목재칩의 혼합량이 많을수록 낮은 경향을 나타냈다. 그리고 비료 용찰실험 결과 비료를 첨가하지 않은 칩과 비교시 비료를 첨가한 칩에서 인, 칼륨, 몰디브덴의 성분이 높게 나온 것으로 보아 비료의 주입은 성공적임을 알 수 있었다

  • This study is carried out to make the environmentally affinitive porous planting block for revegetation and to make a effective program for greening plans. The summary is shown below. 1. In order to get stronger intensity and distribute proper porosity in the block for planting, the cements mixed with fine soil were used and the finer in soil grains gives the stronger in intensity of the cements. Use of the furnace slag cements instead of the portland cements showed relatively stronger in intensity of the block. The intensity of the block became stronger when the mixed ratio of the cements to soil is 5 : 1, but the pore space ratio was lower. The percolate pH of the portland cements after one month of treatment was 13.1 but the percolate pH of the furnace slag cements was shown lower. To mold proper porous planting blocks, the proper combination of additives such as the dehydrating agent, elastic agent and adhesives into the mixture of cements and soil gives better effectives. 2. After molding the porous planting blocks, it gave a better result when the grains of the filler made of peat moss, upland soil and compound fertilizer were smaller than 2 mm in size. Shaking of the filling materials also gave the better result, but it took more time and cost much more. Therefore, it was better when the filling materials were mixed with water first then flew down for stuffing. 3. It was necessary to cover with soil after seeding or planting on the porous planting blocks. The proper thickness of the soil to help root development and keep moisture is about 3~5 cm. 4. The plants for planting on the porous planting block were required stronger in the growth condition of their roots and their environmental adaptability. The average germination percentage and rate of Platycodon grandiflorum on the porous planting block were 88.8% and 85% accordingly and their rate is very uniform. The germination rates of Dianthus superbus var. longicalycinus and Taraxacum officinale were more than 50%. These grass species, Chelidonium majus var. asiaticum, Lysimachia mauritiana and Scabiosa mansenensis were the suggested biennial grasses in the planting area where exchanging of the seedling or nursery plants was not necessary because their germination rates were 59.3, 45.6 and 40.3% accordingly. Viola kapsanensis, Chrysanthemum sp., Taraxacum sp. and Iris ensata var. spontanea are the grass species that could be used by seeding for greening. However, the germination rate of Solidago virga-aurea var. asiatica, Aster scaber and Lythrum anceps were lower than 10%. The coverage ratio of Ixeris stolonifera is more than 80% after 60 days seeding and the root length of most of species are more than 10 cm except Iris ensata var. spontanea and Platycodon grandiflorum because their root developed thicker than other species.

  • Urban problems are constantly occurring around the world due to rapid industrialization and population decline. In particular, as the number of vacant houses is gradually increasing as the population decreases, it is necessary to prepare countermeasures. A plan to utilize vacant houses has emerged to restore the natural environment of the urban ecosystem where forest destruction, damage to habitats of wild animals and plants, and disconnection have occurred due to large-scale development. Through connectivity analysis, it is possible to understand the overall ecosystem flow based on the movement of species and predict the effect when vacant houses are converted into green spaces. Therefore, this study analyzed the green area network to confirm the possibility of greening of vacant houses neglected in Jeonju based on circuit theory. Using Circuitscape and Least-cost path, we tried to identify the connectivity of green areas and propose an ecological axis based on the analysis. In order to apply the resistance values required for analysis based on previous studies, the 2020 subdivision land cover data were integrated into the major classification evaluation items. When the eight forests in the target site were analyzed as the standard, the overall connectivity and connectivity between forests in the area were high, so it is judged that the existing green areas can perform various functions, such as species movement and provision of habitats. Based on the results of the connectivity analysis, the importance of vacant houses was calculated and the top 20 vacant houses were identified, and it was confirmed that the higher the ranking, the more positive the degree of landscape connectivity was when converted to green areas. In addition, it was confirmed that the results of analyzing the least-cost path based on the resistance values such as connectivity analysis and the existing conceptual map showed some differences when comparing the ecological axes in the form. As a result of checking the vacant houses corresponding to the relevant axis based on the width standards of the main and sub-green areas, a total of 30 vacant houses were included in the 200m width and 6 vacant houses in the 80m width. It is judged that the conversion of vacant houses to green space can contribute to biodiversity conservation as well as connectivity between habitats of species as it is coupled with improved green space connectivity. In addition, it is expected to help solve the problem of vacant houses in the future by showing the possibility of using vacant houses.

  • Greening sometimes fails because its method is not suitable for various site conditions, therefore the trend of selecting a revegetation method in Korea today is through test construction. However, due to enlargement, complication and diversification of domestic construction businesses, the importance of VE is gradually increasing as effective efforts over a whole life-cycle to obtain goals such as quality improvement and cost reduction, and not only quality and economic efficiency but also substantiality need to be considered in comparing revegetation methods. For this study, Sungnam~Janghowon (area1), where comparatively various slope revegetation methods are used, was selected the investigation site. The site was divided into three areas:blasting rock, ripping rock and earth sand. The revegetation methods used were six in the blasting rock area, five in the ripping rock area, and two in the earth sand region. 2007 monitoring data was analyzed, and Value (V) was calculated with LCC related ratio, and compared and contrasted with the evaluation of prior revegetation methods. Therefore it is believed that this analysis enables selection of the most appropriate method, unbiased towards one particular characteristic such as quality, vegetation growth and economy. When aiming for a durable effect, it shall be more efficient to select the most appropriate method focusing on LCC analysis, which deals with the economic aspect, as well as the design function aspect.
