Abstract Previously, we selected bacterial strain ISE14 through a sequential selection procedure that included radicle, seedling, and in planta assays and field tests. This strain not only suppressed a destructive soilborne disease, Phytophthora blight, caused by Phytophthora capsici but also increased fruit yields of pepper plants in the fields. This study was conducted to identify strain ISE14 by 16S rRNA gene sequence analysis and to characterise biocontrol and plant growth promotion activiti

Plant responses to drought stress vary depending on the severity of stress and the stage of drought progression. To improve the understanding of such responses, the leaf physiology, abscisic acid (ABA) concentration, and expression of genes associated with ABA metabolism and signalling were investigated in Petunia × hybrida. Plants were exposed to different specific substrate water contents (θ = 0.10, 0.20, 0.30, or 0.40 m(3)·m(-3)) to induce varying levels of drought stress. Plant responses wer

We conducted a three-stage genome-wide association study (GWAS) of response to antidepressant drugs in an ethnically homogeneous sample of Korean patients in untreated episodes of nonpsychotic unipolar depression, mostly of mature onset. Strict quality control was maintained in case selection, diagnosis, verification of adherence and outcome assessments. Analyzed cases completed 6 weeks of treatment with adequate plasma drug concentrations. The overall successful completion rate was 85.5%. Four

UV-A radiation (320–400 nm) is an abiotic stressor that may be used to enhance the production of beneficial secondary metabolites in crops such as leafy vegetables. However, tradeoffs between enhanced phytochemical contents and overall growth/yield reductions have been reported. The responses varied depending on the UV-A intensity, spectral peak, exposure time, species, and varieties. We quantified the changes in growth, morphology, photosynthesis, and phenolic contents of sweet basil grown unde

Many ornamental plant growers water excessively to reduce the risk of drought stress. Scheduling irrigation in greenhouses is challenging because there is little quantitative information about ornamental plant water requirements and how water use changes when plants are grown in varying greenhouse environmental conditions. Models to estimate the daily water use (DWU) of greenhouse crops may provide a useful tool to conserve irrigation water. Our objective was to develop a model to predict DWU ba

Different light qualities affect plant growth and physiological responses, including stomatal openings. However, most researchers have focused on stomatal responses to red and blue light only, and the direct measurement of evapotranspiration has not been examined. Therefore, we quantified the evapotranspiration of sweet basil under various red (R), green (G), and blue (B) combinations using light-emitting diodes (LEDs) and investigated its stomatal responses. Seedlings were subjected to five dif

The concentric dual-buoy Wave Energy Converter (WEC), which consists of external buoy (hallow-cylinder) with toroidal appendage and cylindrical internal buoy within the moon-pool is suggested in this research and its performance in various wave conditions is studied. The Linear Electric Generator (LEG), consisting of a permanent magnet and coils, is used as a direct Power Take-Off (PTO) system. To maximize the electrical energy extracted from the PTO system, the relative heave motions between th

Our understanding of plant responses to drought has improved over the decades. However, the importance of the rate of drought imposition on the response is still poorly understood. To test the importance of the rate at which drought stress develops, whole-plant photosynthesis (P(net) ), respiration (R(dark) ), daily carbon gain (DCG), daily evapotranspiration (DET) and water use efficiency (WUE) of vinca (Catharanthus roseus), subjected to different drought imposition rates, were investigated. W

Variegated foliage plants are often used in interiorscaping in low light environments. The changes in leaf morphology and coloration of two variegated foliage plants, english ivy ( Hedera helix ‘Golden Ingot’) and polka dot plant ( Hypoestes phyllostachya ), under various light intensities [photosynthetic photon flux ( PPF ) at 2.7, 6.75, 13.5, 67.5, and 135 μmol·m −2 ·s −1 ] were investigated to elucidate their optimum indoor light environment. Digital image analysis was used to quantify the ch

이 연구의 목적은 최근에 한국 사회 및 교육 현장을 뒤덮는 창의･융합의개념을 독서 및 독서 교육의 관점에서 비판적으로 고찰하는 데 있다. 독서가창의･융합을 위한 기초적인 지적 활동이며, 창의･융합적 사고의 기본적 토대라는 사실은 누구도 부인하기 어렵다. 그런데 그 개념적 모호성으로 인해창의･융합으로서의 독서의 개념은 무엇인지 생각해 볼 필요가 있다. 국내에서 통용되는 ‘창의･융합’이라는 개념은 과학의 거시적 이론을 위한통섭, 학제 간 연구 및 신융합 학문, 미래 사회를 위한 국가 전략, 기업･사회에서 요구하는 인재 교육 등 다양한 역사적･사회적 산물이다. 창의･융합의개념적 중요성이 사회적으로 인정되지만, 그 개념이 무엇인지 다소 모호한면이 있으며, 이러한 현실은 독서 분야에서도 별반 다르지 않다. 독서 관련이론을 탐색한 결과, 독서 과정 및 독서 발달 이론에서 창의･융합과 관련된논의는 찾아보기 어려웠다. 이들 논의를 바탕으로, 창의･융합과 관련한 독서교육에 시사하는 점을 제시하였다.

Ecosystem services refer to the benefits provided to humans by the natural environment and healthy ecosystems. Green roofs can be used to enhance ecosystem services, which are reduced by urbanization. Moreover, green roofs can improve biodiversity by connecting green spaces. Therefore, it is necessary to examine the multi-dimensional contributions of green roofs to urban ecosystems. To this end, we used i-Tree Canopy to identify changes in land cover and tree canopy ecosystem services from 2003
