Recent changes in rainfall patterns driven by climate change, including localized heavy rainfall, droughts, and prolonged rainy seasons, have significantly impacted grapevine growth quality. An analysis of South Korea from 1995 to 2024 revealed that 54.5–58.0% the annual average precipitation 1357 mm occurs during fruit enlargement period June August, at an seven consecutive days indicating a heightened potential for exposure increased soil moisture stress annually. This study evaluated...

Recent meteorological variability in winter and spring complicates predicting managing frost damage apples pears. This study investigated the relationship between injury during flowering stages of (‘Hongro’ ‘Fuji’) pears (‘Wonwhang’ ‘Niitaka’) weather conditions across regions at varying altitudes. Orchards were categorized into coastal, inland, mid-mountainous, mountainous regions, analyzed. The period apples, from onset blooming to full bloom, averaged approximately 15 days, which was...

Many of these initiatives were based on their policies laid down a strategy. This paper explores common different development status policy strategies twenty countries. As result, this presents some similarities dissimilarities policy. The resemblance might imply that is considered as interest. differences could indicate interests...

본 연구는 2년에 걸쳐 ‘감홍’ 품종에 석회유황합제(Lime sulfur), MaxCel(1.9% BA), Fruitone(3.5% NAA)을 처리하여 적과와 과실품질에 미치는 영향을 조사하였다. 1차년도 약제 처리에 의한 과총당 착과수는 석회유황합제 3회 처리구는 0.82개, MaxCel(10mm) 처리구 역시 1.15개로 무처리구 1.74개에 비해 유의하게 적어 적과 효과가 인정되었다. 과실의 착과수 는 또는 처리 시 단일과 착과율이 각각 47.9%와 48.7%로 무처리 36.0%에 비하여 높았고, 3개 이상 과실 1.4%와 5.8%로 22.9%에 낮아 좋은 효과를 보였다. 액화아의 경우 및 0.36개와 0.50개로 1.20개에 정화아에서와 비슷하게 우수한 보였 다. 2년차 효과는 무처리를 제외한 모든 처리구에서 높은 보였고, 처리가 영향은 없 었다. 따라서, 또는M axCel 혼용처리보다 단용처리만으로도 착과수를 감소시키는데 있었다

Plastics have become indispensable in modern industries; however, their resistance to natural degradation poses environmental challenges. Biological technologies employing microorganisms offer promising solutions. Here, we analyzed the transcriptome and proteome of Pseudomonas aeruginosa, a plastic-degrading microorganism found gut superworms, identify genes enzymes upregulated during polyethylene degradation. Functional analyses these using Kyoto Encyclopedia Genes Genomes Gene Ontology...

This study was conducted to investigate changes in the adhesivity of 'Fuji' apple (Malus domestica Borkh) fruits during period when typhoons mainly occur and obtain agricultural engineering information related fruit drop through a simulation using wind tunnel shaking table. Fruit assessed by measuring tensile force at time pulling from tree. growing season (July September) tended decrease as maturity approached, but this not statistically significant. On other hand, measured artificial...

한국전파법에서 휴대전화에만 적용되었던 전자파흡수율(SAR: Specific Absorption Rate) 측정 대상기기가 2012년 1월 이후 인체로부터 20 cm 이내에 위치하는 휴대용 송신 무선통신기기로 확대됨에 따라 150 MHz 대역의 무전기가 포함되어 이에 대한 SAR 적합성 평가를 위한 측정방법이 필요하다. 그러나 현재 측정방법에 국제표준(IEC 62209-2)에서는 300 대역 이상의 주파수에 대해서 적용하고 있으며, 상용 측정시스템에서도 대해서만 측정이 가능하도록 되어 있는 실정이다. 본 논문에서는 유효성 기준 다이폴 안테나(복사체 길이: 760 mm, 반사 손실 : -25.48 dB) 및 평면형 모의인체의 크기(<TEX>$1,300 mm(L){\times}900 mm(W){\times}200 mm(H)$</TEX>), 수치해석 목표값(1 g: 1.08 W/kg, 10 0.77 W/kg)을 제시하였다. 제시된 안테나 모의인체를 제작하여 측정시스템의 여부를...

'홍로'/M.9 사과나무 세장방추형의 생산성을 높이기 위하여 수고에 따른 투광율, 투약율, 수체생육, 과실 품질, 그리고 노동 비교 분석하였다. 수고가 높을수록 수관내부, 특히 낮은 수관위치에서의 투광률은 감소하였다. 엽면적지수(LAI)는 증가하였으나 엽면적지수의 증가는 수관 내부 농약 살포 효과를 감소시켰다. 신초 생장은 높을 때 가늘고 길게 자라는 경향이었고, 과실의 착색도는 감소하였으나, 경도와 산함량은 차이가 없었다. 주당 착과수는 증가하였으나, 305g 이상의 대과 생산량은 높아질수록 적화, 적과, 전정, 수확 등에 필요한 노동력은 높은 수고에서의 노동력 고소작업차를 투입하여 해결할 수 있었다. 4.5m 수고에서 적화 작업의 경우 사다리보다 전동고소작업차를 이용했을 작업시간은 14.6분/주가 절약되었다. 투광율 향상과 과실착색도 증진을 수관내부의 광환경 개선이 필요함을 알 있다. This study was carried out to determine the...
