Abstract. Plant transpiration links physiological responses of vegetation to water supply and demand with hydrological, energy, carbon budgets at the land–atmosphere interface. However, despite being main land evaporative flux global scale, its response environmental drivers are currently not well constrained by observations. Here we introduce first compilation whole-plant data from sap flow measurements (SAPFLUXNET, https://sapfluxnet.creaf.cat/, last access: 8 June 2021). We harmonized...

Fatal injury and accidents in the construction industry occur under influence of outdoor weather conditions such as temperature, humidity wind speed all four seasons. Previous research this area has focused on hot cold conditions: causes heat rash, cramps fainting, while fatigue, lumbago, finger sensations. However, other are also associated with, cause, fatal accidents. Accordingly, study analyzes based physiological equivalent temperature (PET) it pertains to thermal comfort using an...
In the era of extreme weather events, plant resistance to excessive water should be considered for plantations in frequently flooded areas. Therefore, we quantified irrigation (REI) seedlings six conifer species on basis their morphological, physiological, and biochemical traits. Two different regimes, natural precipitation as a control treatment additional by sprinklers (30.89 ± 2.80 % above precipitation) irrigation, were applied three consecutive years. There distinct responses biomass...
Stable isotopes of water (δ2H and δ18O) are reliable tracers for the investigation plant–soil–water interactions in forest ecosystems. However, variations isotopic compositions may arise due to differences analytical instruments extraction methods. In this study, we conducted three different experiments identify caused by methodological variations. First, analyzed soil using two most commonly applied methods: isotope ratio mass spectrometry (IRMS) cavity ring-down spectroscopy (CRDS)....
Waterlogging induces oxidative damage by accumulation of reactive oxygen species due to stomatal closure. Plants alter their physiological and molecular mechanisms reduce adapt stress. This mechanism adaptation stress, known as hardening, can support future stress tolerance. Pinus densiflora seedlings were grown under waterlogging treatment for three years then transplanted another site identify the hardening effect on transplanting. Transcriptome analysis was conducted before after...
PM10 is known to have a great adverse effect on the human body. However, there lack of research analyzing impact occurrence accidents. Accordingly, purpose this study analyze correlation between and accidents in construction industry present new concentration group manage caused by industry. This was conducted following four stages. (i) collection data, (ii) classification (iii) relative probability analysis, (iv) modified classification. The main results are as follows. When frequency...
점 클라우드로부터 차량을 추출하는 다양한 방식 중 OBPCA 방식은 세그먼트 단위의 평가-분류로 정확도가 높고, 단순한 직사각형 평면도에서 특성 값들을 추출하므로 분류가 빠르다. 그러나 이 차량과 크기가 비슷한 직육면체 모양의 물체를 구별하지 못하는 문제를 가지므로 이를 극복하고 차량 추출의 정확도를 높이는 방안에 대한 연구가 필요하다. 본 논문에서는 해결하기 위해 수평 단면과 함께 수직 단면을 이용하는 확장 방식을 제안한다. 제안 방법은 통해 후보를 1차로 선별하고, 각 후보에서 가장 특징적인 찾아서 그 단면의 임계값들과 비교하여 여부를 판단한다. 비교실험에서는 제안방식이 기존 방식에 비해 정밀도가 6.61% 향상되고 위양성률이 13.96% 감소됨을 확인했으며, 방식이 분류오류 문제에 대해 효과적인 해결방안임을 보였다. Among various vehicle extraction techniques, (Object-Based Point Cloud Analysis)...
This study discuss the antifungal performance of mortars with various organic and inorganic agent on five kinds mold: Chaetomium globosum, Aspergillus niger, Aureobasidium pullulans, Gliocladium virens Penicillium pinophilum, which can be easily discovered in interiors exteriors buildings. Various using agents were made this study, performance, durability activity chemical stability them investigated. As results, mortar 10% Df-45 exhibited outstanding as well activity. The presented overall...
Owing to industrialization and urbanization in recent decades, fine particulate matter (PM2.5) the atmosphere has become a major environmental problem worldwide. Accordingly, importance of air-purifying forests is increasing; however, there lack continuous long-term forest management efficiently mitigate PM2.5. In this study, we analyzed PM2.5 reduction efficiency (PMRE) by comparing seasonal concentrations inside outside for one year. addition, PMREs different types were compared, their...
