The purpose of this paper is to examine the trend on the change of the cherry blossom flowering time due to the temperature change by selecting regions that have long periods of cherry blossom flowering time data as cases. With the flowering time data, the distribution of cherry blossom flowering time, time series change and change rate of cherry blossom flowering time were analyzed. Also, the correlation between the cherry blossom flowering time and the temperature was analyzed. The flowering of cherry blossom is earlier in metropolitan areas, and in the east coastal region than the west coastal region. The trend on the change of the cherry blossom flowering time is very similar to change the temperature. The change rate of the cherry blossom flowering time is rising up in the whole regions under study, and is relatively high in metropolitan areas. Especially, the cherry blossom flowering time festinated greatly in Pohang that is one of the heavily industrialized cities. From the analysis of correlation analysis between cherry blossom flowering time and temperature elements, the cherry blossom flowering time is highly related with mean temperature of March, which the month is just before the beginning of flowering.

이 연구는 지금까지 논의하지 않았던 근대 부산에서 벚꽃 명소의 실상을 밝히기 위하여 당시 부산에서 발간된 일간지 <부산일보(釜山日報)>와 <조선시보(朝鮮時報)>에 게재된 벚꽃 구경과 벚꽃 놀이의 기사를 발굴하여 그 장소를 토지 이용의 유형별로 분류하고, 벚꽃 구경에서 벚꽃 놀이로 변환하는 시기의 동정과 장소적 특성을 고찰하였다. 근대 부산에서 벚꽃의 명소에 관련한 신문기사는 봄의 도래를 알리는 계절화로서 벚꽃이 피어 있는 장소를 알리는 내용에서 점차 벚꽃이 군생하고 있는 장소에 모여드는 사람들의 유흥 행위를 소개하는 것으로 변화되어 간다. 단순히 벚꽃이 화려하게 피어 있는 장소는 신문지상에서 노출되는 빈도는 점점 적어지고, 벚꽃이 만개한 행락지에서 유흥 내용의 소개로 변화해 갔다. 이것은 근대 부산에서 벚꽃의 명소는 벚꽃 구경의 명소에서 벚꽃놀이의 명소로 성숙해갔다는 것을 의미한다. 첫째, 근대 부산의 벚꽃의 명소는 개인주택정원, 온천 여관의 정원, 사찰, 수원지, 배수지, 학교 등 공공용지, 동래온천장, 미도리마치 유곽 등 상점가로 나눌 수 있었다. 장소는 정주 환경의 가장자리, 다시 말해서 도시와 자연의 접점공간에 형성되었다. 둘째, 근대 부산의 벚꽃 명소는 1920년 무렵부터 벚꽃 구경에서 벚꽃 놀이로 변환되었다. 벚꽃의 명소가 성립한 것은 1920년 무렵으로 볼 수 있다. 그리고 벚꽃 구경의 명소가 개인 주택 정원, 배수지 등 공공의 접근의 어려운 곳도 거론되었지만, 벚꽃놀이의 명소는 누구나가 접근할 수 있는 공공의 장소가 주로 거론되었다. 벚꽃의 명소가 봄철 행락지가 되었다.

After transitioning from periodic to model-based control policy for fire blight blossom infection, it is crucial to provide the timing of field application with easy and accurate information. To assess the risk of blossom infection, Maryblyt was employed in 31 sites across apple-producing regions nationwide, including areas prone to fire blight outbreaks, from 2021 to 2023. In 2021 and 2023, two and seven sites experienced Blossom Infection Risk-Infection warning occurrences among 31 sites, respectively. However, in 2022, most of the sites observed Blossom Infection Risk-Infection from April 25 to 28, highlighting the need for blossom infection control. For the comparison between the two model-based control approaches, we established treatment 1, which involved control measures according to the Blossom Infection Risk-Infection warning and treatment 2, aimed at maintaining the Epiphytic Infection Potential below 100. The analysis of control values between these treatments revealed that treatment 2 was more effective in reducing Blossom Infection Risk-Infection and the number of days with Epiphytic Infection Potential above 100, with respective averages of 95.6% and 93.0% over the three years. Since 2022, the implementation of the K-Maryblyt system and the deployment of Automated Weather Stations capable of measuring orchard weather conditions, with an average of 10 stations per major apple fire blight county nationwide, have taken place. These advancements will enable the provision of more accurate and timely information for farmers based on fire blight models in the future.

Blossom-end rot is probably the most recognizable Ca deficiency that affects fruit production including pepper. We investigated the induction of blossom-end rot during the period of rapid vegetative growth and fruit setting, and the effect of Ca fertilization on the suppression of blossom-end rot in pepper plants grown in a plastic-film house. During the first fruit setting period, more than 60% of pepper fruits larger than 8 cm showed the symptoms of blossom-end rot. Under the condition of transpiration occurring at a much faster rate, growing leaves of pepper plants could be the greater sinks for Ca than developing fruits. The incidence of blossom-end rot was significantly decreased after two weeks of Ca fertigation. Calcium application during the rapid vegetative growth and fruit setting period could be suggested as a preventive step to overcome the local Ca deficiency inducing blossom-end rot of pepper fruits.

본 논문에서는 drag-sail의 수납 효율을 높이기 위해 새로운 접기 방법인 blossom method를 제안하였다. 가항력 돛을 접을수록 두께가 늘어남에 따라 발생하는 문제점을 해결하기 위해 접히는 라인에 여유 공간(offset)을 주고, offset film 라인이 교차하는 지점에는 구멍을 뚫어 film의 일그러짐을 방지하였다. 또한, blossom method의 적용 가능성을 확인하기 위해 mylar film으로 제작하여 전개 실험을 수행하였다. Blossom method를 적용할 경우, 수납부피 대비 전개면적 비인 수납비는 1: 68.64로 기존의 가항력 돛 접기 방법인 z-fold method보다 약 1.88배 향상되었으며, 전개 실험 결과 구멍이나 jamming에 의한 손상이 없는 것을 확인하였다.

The causal agents of bacterial blossom blight in kiwifruit were isolated from flowers displaying symptoms in Korea. The pathogens were characterized by biochemical and physiological tests, and identified on the basis of 16S rDNA and 16S-23S internal transcribed spacer (ITS) sequences. Pathogenicity tests demonstrated that the blossom blight of kiwifruit in Korea is caused by two pathogens, Pseudomonas syringae pv. syringae and P. fluorescens. Carbon source utilization and DNA-DNA hybridization experiments confirmed P. fluorescens as one of the causal agents of blossom blight of kiwifruit. P. syringae pv. syringae and P. fluorescens can be distinguished from each other by the symptoms they produce in flowers. P. syringae pv. syringae primarily affected the stamen, while P. fluorescens caused rotting of all internal tissues of buds or flowers.

To preventively control fire blight in apple trees and determine policies regarding field monitoring, the Maryblyt ver. 7.1 model (MARYBLYT) was evaluated in the cities of Chungju, Jecheon, and Eumseong in Korea from 2015 to 2020. The number of blossom infection alerts was the highest in 2020 and the lowest in 2017 and 2018. And the common feature of MARYBLYT blossom infection risks during the flowering period was that the time of BIR-High or BIR-Infection alerts was the same regardless of location. The flowering periods of the trees required to operate the model varied according to the year and geographic location. The model predicts the risk of "Infection" during the flowering periods, and recommends the appropriate times to control blossom infection. In 2020, when flower blight was severe, the difference between the expected date of blossom blight symptoms presented by MARYBLYT and the date of actual symptom detection was only 1-3 days, implying that MARYBLYT is highly accurate. As the model was originally developed based on data obtained from the eastern region of the United States, which has a climate similar to that of Korea, this model can be used in Korea. To improve field utilization, however, the entire flowering period of multiple apple varieties needs to be considered when the model is applied. MARYBLYT is believed to be a useful tool for determining when to control and monitor apple cultivation areas that suffer from serious fire blight problems.
