Global climate change caused by industrialization has caused abnormal weather conditions such as urban temperatures and tropical nights, urban heat waves, heat waves, and heavy rains. Therefore, the study tried to analyze climate conditions and weather conditions in the streets and analyze climate factors and meteorological factors that lead to inconvenience to citizens. In the case of trees, the overall temperature, surface temperature, solar irradiance, and net radiation were measured low, and the temperature was lower in the Pedestrian road than in roads. The dry bulb temperature, the black bulb temperature, and the wet bulb temperature for the thermal evaluation showed the same tendency. In the case of thermal evaluation, there was a similar tendency to temperature in WBGT, MRT, and UTCI, and varied differences between types. Although the correlation between the meteorological environment and the thermal environment showed a statistically significant significance, the difference between the measured items was not significant. The study found that the trees were generally pleasant to weather and thermal climate in the form of trees, and the differences were mostly documented.

This study was conducted to establish the type and method of fertilization for no-tillage during the third year of No-tillage (NT) and Conventional-tillage (CT) practices, towards different kinds of fertilizers. In this experiment, the livestock manure showed higher in response to fertilizer effects of no-tillage. Comparing growth characteristics and yield in NT and CT. Regarding yield, there is no significant between livestock fertilizer and chemical fertilizer, but between livestock fertilizer and chemical fertilizer in conventional fertilization has significant differences. Based on the result, livestock fertilizer is effective way on the quantity of the crop. Nitrogen absorption of plant in livestock of no-tillage is more effective than conventional fertilization. In case of the phosphorus absorption and potassium absorption of plant, fertilizer effect has no significant. Nitrogen is highly absorbed in livestock fertilization of NT. Absorption of phosphorus and potassium are similar.

This study investigated the effect of leaf form or phenotype and light intensity on the toluene, xylene, and ethylbenzene removal of three foliage plants. Green and variegated forms of Ardisia pusilla, Scindapsus aureus, and Hedera helix plants were grown under 10 and 20 μmol･m-2･s-1 light intensities for 8 months and were tested for their volatile organic compound (VOC) removal efficiency for 15 h. In general, variegated forms of the plant species have higher VOC removal after 15 h of VOC exposure than green plants, particularly when grown in 10 μmol･m-2･s-1. This is more evident in A. pusilla and S. aureus than in H. helix. The highest rate of toluene, m-, p-, and o-xylene removal per hour by plants grown under 10 μmol･m-2･s-1 was achieved by variegated A. pusilla, while for ethylbenzene, variegated A. pusilla and variegated H. helix had the highest removal rate per hour. In plants grown in 20 μmol･m-2･s-1 light intensity, variegated and green H. helix have the highest removal rate per hour of toluene and m-, p-, and o-xylene. For ethylbenzene, variegated A. pusilla and green and variegated H. helix had the highest removal rates per hour. The plant with the lowest removal rate per hour for all five VOCs was green S. aureus grown under both light intensities. The percentage VOC removal rate of variegated over green plants was 22% higher at a lower light intensity

Hericium erinaceus is considered a functional food and potential medicinal source. The present study was conducted to examine the potential antioxidant and anti-inflammatory activities of carried out with water and ethanol extracts of Hericium erinaceus grown on germinated green rice (HEGR-W and HEGR-E, respectively) and the water and ethanol extracts of germinated green rice (GR-W and GR-E, respectively) as potential medicinal resources or antioxidant and anti-inflammatory agents. Methods and Results: The total phenolic and flavonoid contents, DPPH, and ABTS activity, reducing power, DNA protective activity, cell viability, and NO production were investigated. The total phenolic and flavonoid contents were highest in HEGR-E (66.53 ± 2.40 ㎎·GAE/100 g and 82.12 ± 7.10 ㎎·CE/100 g respectively). HEGR-E exhibited high DPPH (44.70 ± 1.28%) and, ABTS (44.70 ± 1.28%) activity and reducing power (0.219). HEGR and GR extracts showed protective activity against DNA damage. The cytotoxicity of HEGR and GR in RAW264.7 cells and LPS-induced RAW264.7 cells was low. HEGR-E and GR-W exhibited anti-inflammatory effects through a 28% inhibition of NO production in LPS-induced RAW264.7 cells. Conclusions: These results suggested that the extracts of Hericium erinaceus grown on germinated green rice could be a potential medicinal material with natural antioxidant and NO inhibitory properties.

The objective of this study was to compare antioxidant activities of green tea, rosemary, lemon and bamboo leaves extracts using three different extraction methods (80% ethanol sonication extraction, distilled water autoclave extraction, distilled water extraction at room temperature). As a result, green tea and rosemary extracts showed relatively high antioxidant activities compared with those of lemon and bamboo leaves. These green tea and rosemary extracts were subsequently added to soymilk and their mixtures were examined for antioxidant activities. Soymilk added with 10% green tea distilled water autoclave extracts and distilled water at room temperature extracts showed relatively high DPPH, 85.09±2.26%, 84.38±1.97%, and ABTS radical scavenging activities, 73.43±2.78%, 81.34±4.78%, respectively. On the other hand, soymilk added with 10% rosemary distilled water autoclave extracts showed remarkably higher DPPH radical scavenging activity while their ABTS radical scavenging ability was similar to that of non-added soymilk. In conclusion, our results suggest that the addition of green tea distilled water autoclave extracts, distilled water at room temperature extracts and rosemary distilled water autoclave extracts to soymilk could contribute to the development of added value soymilk products with increased antioxidant activities.

With the goal of developing a new functional fermentation milk using green tea powder (GP), milk was fermented with direct vat set (DVS) starter culture containing Streptococcus salivarius subsp. thermophilus, Lactobacillus paracasei and L. delbrueckii subsp. bulgaricus. We investigated fermentation characteristics and antioxidative activities of fermented milk supplemented with different concentrations (0.5, 1, 2, 3%) of GP. All samples were evaluated for pH, total acidity, viable cell count, and sugar contents. The pH of all samples decreased during fermentation, and the final pH ranged from 4.35 to 4.51. The acidity increased during fermentation, after the fermentation was completed, the titratable acidity was 0.8 to 1.1%. And viable cell count of all samples increased during fermentation, and the final viable cell count was 8.57 to 8.89 log CFU/mL. The sugar content decreased as the fermentation proceeded and finally reached 12 to 13 ˚Brix. And increasing GP, decreased brightness and increased yellowness. Increasing GP concentration added to milk, improved DPPH free radical scavenging activity and ferric ion reducing activity of fermentation milk. The fermentation milk kept their pH, total acidity and viable cell counts standard of fermentation milk during the storage period at 4℃. These findings confirmed the possibility of development of the novel functional fermentation milk through the investigation of the quality characteristics of the fermentation milk added with GP.

A new colored soybean variety ‘Jungmo3005’ was developed as a breeding parent. ‘Cheongjakong’ and ‘Geomjeongkong3’ were crossed in 2000. F1 and F2 populations were grown for 2 years and selected by pedigree method from F3 to F5. The preliminary yield trial (PYT) and advanced yield trial (AYT) were conducted from 2006 to 2007, and regional yield trial (RYT) in 9 regions was conducted from 2008 to 2010. ‘Jungmo3005’ is determinate, white flower, green cotyledon, green spherical seed and yellow hilum. Flowering date and maturing date were July 30 and Oct. 7, respectively. Other quantitative characteristics of ‘Jungmo3005’ were similar to ‘Cheongdu1’, but it was more tolerant to lodging and shattering than ‘Cheongdu1’ at RYT field and indoor test. Although ‘Jungmo3005’ showed symptom of mosaic disease in inoculation test at greenhouse, it had high level of resistance to soybean mosaic virus and bacterial pustule diseases at field. The yield of tofu of ‘Jungmo3005’ was more than that of ‘Cheongdu1’. The mean yield of ‘Jungmo3005’ in RYT was 256kg/10a which was 97% of the yield of ‘Cheongdu1’. ‘Jungmo3005’ is expected to be widely used as a breeding parent to cross with other varieties and lines for creating colored soybean cultivars with tolerance to lodging, shattering and bacterial pustule.

In this paper, the slope adhesion force of the developed green slope soil was evaluated by simulating rainfall intensity. From the results, the slope failure didn't occur at all conditions. As the slope angle increases, however, the damage decreased. The developed green slope soil is considered to have sufficient adhesion capacity to the slope.

The purpose of this study is to establish common indicators that constitute a "low-carbon green city" and determine their priorities from the perspective of Incheon Metropolitan City with a view to help develop its climate change strategy strategic city. Several major cities, domestic and overseas, were benchmarked to come up with preliminary indicators consisting of six areas, twenty two planning factors, and 74 indicators. In order to evaluate the validity and relevance of preliminary indicators, expert FGI (Focus Group Interview) was conducted that changed the numbers of final indicators to six areas, twenty two planning factors, and 82 indicators. Finally, AHP (Analytic Hierarchy Process) was conducted to assign relative importance (i.e. weights) to each indicator. Through the layering process of AHP, the upper category of "field" and lower category of "planning factors" were set up as policy prerequisites for constructing a low-carbon green city (6 fields, 22 planning factors). The AHP results for the first level (fields), green city space was ranked first, followed by energy and resource circulation, green traffic, ecological preservation, green logistics, and governance. Among all planning factors, land use, energy efficiency, traffic system improvement, location planning, securing of ecological area, efficiency of logistics, and cooperative organization showed the highest priorities.

This study analyzed the placement shape and correlation of green space focusing on anion that is one of curing substances. As its result, it was found out that the meteorological element becomes different and the generated amount of anion also gets different along such different meteorological element in case the shape of placing green space. As the result of analyzing the correlation with meteorological element , it was analyzed that it was the positive correlation in case of time, temperature and relative humidity and it was also analyzed that it was negative correlation in case of wind velocity and amount of light. But, in case of wind velocity, it was considered that the further complement research is required as the sampling distribution was shown as so biased by the windproof effect of the trees planted at the outskirts of green space in case of wind velocity. Based on th analyzed results as above, it suggested the model of generating anion by implementing multiple regression analysis such as y = -2462.383 + 0.304x1 x 72.746x2 x 7.315x3 x - 0.138x4 (x1; time, x2; air temperature, x3; relative humidity, x4; luminous intensity, R2; 0.691).

Research to reduce urban temperatures and mitigate the Urban Heat Island (UHI) effect has focused primarily on the role of large urban green spaces as cool islands (Oke, 2004;Park et al., 2017). However, the role of small green spaces (SGs) such as street trees and pocket parks has not been fully investigated. The purpose of this research is to assess the mitigating effect of SGs on micro-UHI through a comparative analysis of air temperatures of SGs and non-green spaces (NGs), that include building-shaded spaces (BS) and non-shaded, impervious, paved spaces (PS) completely exposed to sunlight. Six urban blocks were the study site and in a highly developed area, Jongnogu and Junggu, Seoul, 37°34′N 126°58′E, South Korea and also located in the same micro-climatic zone. They had SGs which were vegetation patches presented as distinct areas of tree cover. And they were mapped through aerial images analysis and field survey. The experiment was conducted across six urban blocks in a highly developed area in Seoul, South Korea during daytime in summer. Two researchers at each block simultaneously recorded air temperatures at 1.5 m above the ground level using mobile loggers at one-minute intervals for an hour. Measurements were repeated three times, and 1,296 temperature readings were collected in total and made 174 mean temperature data. ArcGIS was used to perform solar radiation analysis to highlight SGs, BSs, and PSs on a thermal map. The highest air temperatures and the lowest air temperatures of each block were extracted and classified. ANOVA and Kruskal-Wallis H test utilizing SPSS statistics were used to verify the significant differences in mean air temperatures between SGs (TSG), PSs (TPS), and BSs (TBS). As a result, ΔTPS-B (the thermal effect of PSs on a block‘s air temperature) ranged from –1.38 ℃ to 2.28 ℃ with fifty-six points, ΔTBS-B (the thermal effect of BSs on a block’s air temperature) ranged from –2.38 ℃ to 2.38 ℃ with fifty-eight points and ΔTSG-B (the thermal effect of SGs on a block’s air temperature) ranged from –1.98 ℃ to 1.62 ℃ with sixty points. 68% (N = 41) of SGs were a negative number of ΔTSG-B while 50% of BSs shows a negative number. The result means that SGs contribute to reducing microscopic UHI than BSs which have much more shade area than SGs have. The results showed that SGs contributed to significantly reducing TBi up to 2.9 ℃ while BS reduced TBi up to 2.7 ℃. The highest TBi was on a PS. The air temperature difference between SGs and NGs over all the blocks ranged from 0.9 ℃ to 2.9 ℃. The air temperature difference between PS and SG was significant and ranged from 0.2 ℃ to 2.0 ℃, while the difference between BS and SG was significant and ranged from 0.1 ℃ to 1.2 ℃.

본 연구는 옥상녹화 적용을 목적으로 펄라이트와 원예용상토 배합비별 비비추(Hosta longipes (Franch. & Sav.) Matsum.)를 식재한 후 무 관수 처리에 따른 스트레스가 생육에 미치는 영향을 평가하였다. 실험구는 펄라이트:원예용상토를 9:1, 7:3, 5:5, 3:7, 1:9(v/v)로 혼합한 다 음 직경 18cm, 높이 18cm의 플라스틱 용기에 본엽이 6~7매인 비비추를 식재하여 배합비별로 10반복씩 조성하였다. 측정항목으로는 초장, 엽장, 엽폭, 엽수, 엽록소함량, 엽록소형광, 녹엽면적율, 잎의 상대수분함량, 전해질 누출, 토양수분, 생존일수 등을 조사하였다. 초장, 엽장, 엽폭은 펄라이트 비율이 높아질수록 낮아지는 경향을 보였으며, 엽록소함량은 실험초기에는 펄라이트 비율이 높을수록 엽록소함량은 낮 은 경향을 보였으나 시간이 경과하면서 토양배합비율에 따른 차이는 나타나지 않았다. 용적수분함량은 실험시작 21일에는 0%에 도달하 였으며, 그 감소폭은 펄라이트 비율이 높을수록 낮은 경향을 보였다. 엽의 전해질누출은 수분스트레스로 인해 고사직전에 증가하는 경향 을 보였다. 생존일수는 7:3 배합비에서 53.3일로 가장 길었으며, 그 다음으로 9:1이 53.0일, 5:5 48.0일, 3:7 43.7일이었으며, 1:9에서는 40.3 일로 가장 빠르게 고사하는 것으로 나타나 펄라이트 비율이 높을수록 생존기간이 길어지는 것으로 나타났다. 이는 펄라이트의 높은 보수 력이 반영된 결과로 판되며, 펄라이트 비율이 높아질수록 생육적인 측면에서는 불리한 경향을 나타내 5:5 또는 3:7배합비율이 식물생육 측 면에서는 바람직한 것으로 판단된다.

본 연구는 옥상녹화 토심에 따른 온도 및 열류량 차이를 알아보고자 수행하였다. 470×270mm 크기에 높이가 10cm, 20cm, 30cm인 플라스 틱 용기를 각각 12개씩 준비한 후 플라이애쉬(fly-ash)를 채워 잔디를 식재하여 실험구를 조성하였다. 이때 아무것도 식재하지 않은 옥상바 닥을 대조구로 하였다. 실험결과 온도저감은 토심이 깊을수록 크게 나타났으며, 최고온도와 최저온도 차이는 대조구가 29.5℃로 가장 크 게 나타났으며, 그 다음으로 토심 30cm 27.2℃, 20cm 23.5℃, 10cm 23.0℃ 순으로 나타났다. 각 실험구 표면과 토양 하부의 최대온도의 차 이를 살펴보면 토심 30cm가 18.4℃로 가장 높았으며, 그 다음으로 토심 20cm가 16.1℃, 10cm가 14.4℃로 나타났다. 최대온도 도달시간을 살펴보면 토심 30cm는 7시간 50분이 소요되었으며, 토심 20cm는 7시간, 10cm는 4시간 50분으로 나타났다. 열류량의 변화는 측정기간 중 일사량이 가장 높았던 날(873.3W․m-2)을 기준으로 대조구에서는 408.9W․m-2를 나타낸 반면에 토심 20cm -3.8W․m-2, 30cm 2.7W․m-2, 10cm 4.5W․m-2로 나타나 토심이 깊어질수록 열전달이 감소되는 것으로 나타났다. 이상의 결과를 종합하면, 옥상녹화를 조성함으로써 표 면온도의 감소는 물론 외기온도가 전달되는데 지연효과로 인한 차열이나 단열효과로 발생하는 냉난방 에너지 절약으로 이어질 수 있을 것 으로 판단된다.

The main purpose of this study is to investigate the factors that have an impact on public policy, green products and technology in Kuala Lumpur, given government initiatives to boost the environment awareness. The data used in this study was collected by distribution questionnaires randomly in six areas of Kuala Lumpur and 400 respondents were interviewed. Based on a literature review, three hypotheses were stated and tested using structural equation modeling (SEM). SEM is a statistical analysis method that involved two or more variables in analyzing structural relationships among the variables. The SEM model shows that green products and government policies have a direct influence on environmental awareness. However, green technology does not have a direct influence on environmental awareness. Since, knowledge on green technology does not have a significant impact on raising environmental awareness among the public, a much more pragmatic awareness campaign needs to be put in place to use green technology as a part of modern living. The study suggests that the urban population needs to be more aware of the environmental issue as cities tend to have better infrastructure to raise public awareness on green issues. Moreover, the government should increase the environmental awareness among younger generation through workshops, seminars, campaigns, and pamphlets.

Background : This study was carried out to investigate the changes of the growth of ginseng in the house when the light intensity was increased. Three shading screens were used: shading materials 85%, 77%, and 55% net. Changes in the growth of ginseng and the quality of red ginseng were investigated in these shading materials. Methods and Results : The test site was a three house constructed in the Punggi Ginseng Research Institute, Gyeongsangbuk - do Agricultural Research and Extension Services. The entrance to the house is located east-west, and the structure is double steel frame. The inside of the house is covered with vinyl, and 85%, 75%, 55% shading net is installed for each shading treatment. From the end of June to the middle of August, a 55% shading net was double covered to reduce the high temperature damage. The test material was grafted on March 20, 2013. The management of the irrigation water was from 30 kPa to 10 kPa. The aM-21A data log of Wise Sensing Co., Ltd. was used to measure the cultivation environment in the house. Photosynthesis was measured using Lci Compact Photosyntheisi System, adc, UK. Surveys were carried out in accordance with the inspection standards of the Rural Development Administration. The data were analyzed statistically using SPSS. Conclusion : The summer temperature of shading method was more than 2℃ higher than other treatments in 55% shading treatment and more than 6℃ in autumn. The light intensity of 90 μmol/s/㎡ was lower than that of August, and the light intensity was higher than 400 μmol at the end of September. The 55% shading method showed twice as much light in summer and more than four times in autumn. The amount of photosynthesis increased due to the light intensity of 55% treatment, especially in the morning of May. In the light of shading method, 85% light shading method showed the best growth at 2 years, but 55% at 3 years and more, and 5 years at 5 years.

Background : The organic matter content of land clearing or soil brought from an other place is very low, less than 0.5%. However, the organic matter content of natural habitat soil and leader farmhouse soil was two to three times higher than that of general farmhouse soil. As a result, the yield of Gastrodia elata was higher than that of general farmhouse. Therefore, this experiment was carried out to investigate the yield of G. elata according to the application of green manure crops (GMCs). Methods and Results : This experiment was carried out in a soil with organic matter content of 0.5% in rain shelter greenhouse. The kind of GMCs are corn, Sudan grass, sorghum and oats, and the throughputs per 10 a were 2,000 ㎏, 2,200 ㎏, 1,500 ㎏ and 700 ㎏ of each. The soil preparation was carried out after treated of GMCs at least one month before G. elata was formally planted. As the results of these experiment, organic matter content in soils increased 4 - 5 times compared with before treatment. As a result, the yield of G. elata increased by 21 - 41% in all treatments of GMCs. In addition, there was 2 - 5% more G. elata of good merchantable quality. However, the soil temperature in the summer season period of 2016 (7.1 - 8.31) was 1.2 - 1.6℃ higher than the previous year. The day when the outside temperature was above 30℃ was 41 days. It doubled from the previous year. Soil moisture content showed similar tendency according to treatments. As a result, 20 - 30% of high temperature damage and 20 - 50% of putrefaction occurred, and the total yield also decreased by 20 - 30% compared to normal year. Conclusion : In conclusion, some organic matter is needed for cultivation of G. elata. Therefore, it is considered that it would be better to keep the organic matter content at 2 - 3% when the destination are managed, and to use corn or Sudan grass as the GMCs.
