전 세계적으로 농업해충의 약제 저항성 발달에 따른 방제 효율 저하는 농약의 과다 사용을 초래하여 농업의 생산성 저하 및 환경 파괴 문제 등을 야기하고 있다. 뿐만 아니라 위생해충의 경우에도 약제 저항성 발달이 심각한 수준으로 나타남에 따라 인류 보건에 큰 위협이 되고 있다. 해충의 약제 저항성은 자연계에 존재하는 극히 낮은 빈도의 저항성 형질이 반복적인 약제 사용에 따라 선발되는 과정을 통해 발달 되는데, 해충 약제 저항성의 효과적 관리를 위해서는 저항성 발달 기작의 규명과 신속·정확한 진단법의 확립이 필수적이다. 현재까지의 저항성 관리 는 저항성 발달 후 대응적(reactive)으로 이루어져 왔으나, 미래에는 보다 다양한 분자 마커를 활용하여 저항성 형질 빈도를 관리 가능한 수준에서 유지하는 선제적(proactive) 저항성 관리도 가능할 것으로 예상하고 있다. 본 발표에서는 해충 약제 저항성 연구의 현재 상황과 미래 전망에 대해 소개하고자 한다.

몇 종의 주요 농작물 해충에 대한 식물추출물(cinnamon extract 5% + citronella oil 10% + citrus oil 30% + derris extract 10% + neem extract 20% + penetrating surfactant 25%)의 살란 효과를 분무법으로 검정하였다. 노린재류의 경우 알이 부화하는 과정에서 치사하는 경향을 보였다. 식물추출물(500배액) 처리시 썩덩나무노린재(Halyomorpha halys), 톱다리개미허리노린재(Riptortus clavatus), 홍비단노린재(Eurydema dominulus), 온실가루이(Trialeurodes vaprarorium), 담배가루이(Bemisia tabaci), 파밤나방(Spodoptera exigua), 검거세미밤나방(Agrotis ipsilon) 에 대한 최종 살란 효과는 100%로 높게 나타나, 향후 산업화가 가능할 것으로 생각된다.

시설 고추 주요 해충인 꽃노랑총채벌레(Frankliniella occidentalis)의 방제를 위해 유기농업자재들의 단독 처리 및 종합 투입시 방제 효과를 검정 하였다. 황색끈끈이롤트랩은 지제부에 설치하고, 포식성 천적(Hypoaspis miles)은 지제부에 접종하며, 식물추출물(커스터드애플시드 오일 50% + 계 피 추출물 10%)은 경엽살포하는 방식으로써 각각의 단독 처리시 방제 효과는 45.3, 36.6, 50.2%였다. 한편, 3종의 유기농업자재들을 종합 투입했을 경우 고추 수확기 방제 효과가 무처리 대비 62.4~80.9%로 유지되어, 시설 고추 꽃노랑총채벌레 친환경 방제용으로 활용이 가능할 것으로 생각된다.

Recently, ESG management has become a global trend, receiving increasing attention from stakeholders such as consumers, investors, and governments, as regulations related to ESG disclosure and supply chain due diligence have been strengthened since the United Nations Principles of Responsible Investment (UN PRI) was announced in 2006. ESG is an acronym for the environment (E), social (S), and governance (G) and is accepted as a key factor for the continuous survival and growth of a company. As a result, there are over 600 ESG management evaluation indicators operated domestically and internationally, and numerous global initiatives have emerged. Korea’s Ministry of Trade, Industry and Energy also announced “K-ESG Guidelines (December 2011)” and “K-ESG Guidelines for Supply Chain Response (December 22)” to help SMEs introduce ESG management and respond to supply chain due diligence. However, small-scale manufacturing companies with poor financial, human resources, and technological capabilities face significant challenges in introducing ESG management. Accordingly, this study aims to examine the current status of ESG management adoption in small-scale manufacturing companies with less than 150 people in Korea and propose activation plan ESG management based on the diagnostic requirements of the “Supply Chain Response K-ESG Guidelines.”

Background: Sperm quality and the number of sperm introduced into the uterus during artificial insemination (AI) are pivotal factors influencing pregnancy outcomes. However, there have been no reports on the relationship between sperm concentration at AI and sperm quality in Hanwoo cattle. In this study, we examined sperm quality and pregnancy rates after AI using sperm inseminated at different concentrations. Methods: We evaluated the motility, viability, and acrosomal membrane integrity of sperm at different concentrations (10, 15, 18, and 20 million sperm/straw) in 0.5-mL straws. Subsequently, we compared the pregnancy rates after AI with different sperm concentrations. Results: After freeze-thawing, sperm at the assessed concentrations showed similar viability and acrosomal membrane integrity. After AI, cattle in the 10 million group had significantly lower pregnancy rates compared to those in the 18 and 20 million groups. Conversely, there were no statistically significant variances observed between cattle in the 10 and 15 million groups. Conclusions: Sperm at concentrations of 10, 15, 18 and 20 million per straw exhibited comparable motility, viability, and acrosomal membrane integrity. However, a concentration of at least 18 million sperm per straw is required to achieve a consistent rate of pregnancy rate in Hanwoo cattle after AI.

글로벌 게임시장의 성장에 따라 국내 게임이용자도 손쉽게 다양한 국가에서 접할 수 있게 되 었다. 그리고 이러한 글로벌 경쟁 속에서 현실의 다양한 문화 창의적으로 반영한 게임이 점증 하고 있다. 대표적인 것이 중국의 호요버스가 개발한 해제 월드 형<원심>으로, 해당 콘텐츠는 캐릭터와 공간디자인에 다양한 국가의 문 것이 특징이다. 이때 의상디자인은 캐릭터의 성격과 매력을 효과적으로 이국적인 특색을 드러내는 기호라는 점에서 특히 중요하다. 이에 이 글은 먼저 캐릭터 의상과 의상 기호에 관한 검토하고, <원심>의 문화 활용 전략을 간단히 살펴보았 다. 이후 퍼스의 기호학을 활용해 중국의 문화적 특색을 반<원신> 캐릭터 ‘운근’을 분석하였다. 분석 결과, <원신>의 캐릭터 디자인전략은 중국의 풍부한 문화적 문맥을 중심 코드를 적극적으 로 빌리는 한편, 캐릭터 성을 부각하는 방향으로 의상 구성요소를 변형 시 나타났다. 이후 분 석 결과를 바탕으로 차후 연구를 위한 발전 방향을 제시하였다..

Glutamate-mediated oxidative stress causes neuronal cell death by increasing intracellular Ca2+ uptake, reactive oxidative species (ROS) generation, mitogen-activated protein kinase (MAPK) activation, and translocation of apoptosis-inducing factor (AIF) to the nucleus. In the current study, we demonstrated that corydaline exerts potent neuroprotective effects against glutamate-induced neurotoxicity. Treatment with 5 mmol/L glutamate increased cellular Ca2+ influx, ROS generation, MAPK activation, and AIF translocation. In contrast, corydaline treatment decreased cellular Ca2+ influx and ROS generation. Western blot analysis revealed that glutamate-mediated MAPK activation was attenuated by corydaline treatment. We further demonstrated that corydaline treatment inhibited the glutamate-mediated translocation of AIF to the nucleus. We propose that corydaline is a promising lead structure for the development of safe and effective neuroprotectants.

This study evaluated the risk of single and combined exposure to microplastics in zebrafish (Danio rerio) through biomarkers, such as survival rate, excretion rate, and histological alterations of organ systems. The experimental groups were the control (Cont.), single microplastics exposure group (MPs, 1.83%/fish total weight (g)), the copper group (Cu, 21.6 μg L-1), and a group with combined exposure to MPs and copper (MPs*Cu). The experiment was conducted with individual exposure (7 days) for MP excretion rate analysis and group exposure (14 days) for biomarker analysis. The daily excretion rate of MPs tended to decrease in a time-dependent manner. The copper concentration in the body was not significantly different between single and combined copper exposure. The degeneration of mucous cells in the skin, capillary dilation of the gill lamella, increased intestinal mucous, hepatocyte hypertrophy, and the degeneration of glomeruli and renal tubules were observed in all exposure groups. These histological alterations showed the highest tendency in the MPs*Cu group. In this study, the changes in biomarkers were attributed to the single effect of copper or the combined effect of copper and MPs rather than being solely influenced by MPs.

In response to the expanding landscape of the biotechnology industry and the increasing demand for comprehensive drug development as well as the conduct of preclinical and clinical trials, there is a growing need for employment of diverse animal models, including both small and large animals. The focus of this study was on refining ex vivo culture techniques for bioluminescence imaging following administration of intradermal injections in large animals. To examine the feasibility of our approach, varying concentrations of the rFluc protein were administered to rats and live imaging was employed to validate the corresponding levels of expression. Subsequently, following administration of rFluc to mini-pigs, ex vivo analyses were performed on sample tissues to assess the levels of protein expression across different concentrations. In particular, optimal culturing conditions that facilitated the sustained expression of the protein in samples post-euthanasia were identified. Moreover, by employing small animal imaging devices, we were able to capture clear images of the sample plates, which provided evidence of the successful application of our experimental techniques. The findings from this research represent a significant effort toward refining bioluminescence imaging methods tailored for use with large animal models—an imperative facet of contemporary drug development and biomedical research.

This study aimed to explore sustainable fashion design plans and directions by analyzing Marine Serre’s collection. Previous research was reviewed to derive classifications of the aesthetic characteristics of sustainable fashion design. This classification was then used to analyze the characteristics of the Marine Serre collection. Design analysis was conducted on Marine Serre’s 2018 FW to 2023 SS collections. Marine Serre’s sustainability characteristics are functionality, surprise, handicraft, and inclusion. The results are as follows. First, functionality is the highest among the four characteristics and includes the functionality of movement, the functionality of form, and futurism. This characteristic was observed in the use of all-in-one body suits, pockets, and workwear, showing the will and values of designers who value daily activity. Second, surprise includes the scarcity of materials and the unexpectedness of composition. The value of the clothing is enhanced by the use of scarce materials not typically used in clothing. In addition, Marine Serre is highly regarded for expanding clothing into life by incorporating material upcycling into the theme of the collection. Third, handcrafted features include exaggerated decorations, logo, retro designs, and natural properties, and intentional utilization is differentiated. Marine Serre’s signature pattern suggests a suitable expression for the fabric to use the crescent moon for the season. Fourth, the collection expresses themes of inclusivity and cultural diversity. The results indicate that Marine Serre wants to contribute to a better future characterized by global coexistence.

Bangladeshi medicinal plants (BMP) have a history of traditional use in treating chronic inflammatory diseases, but a BMP bark’s antioxidant and anti-inflammatory effects remain largely unexplored. This study assessed methanolic extracts’ antioxidant and anti-inflammatory properties from the bark of 15 medicinal plant species native to Bangladesh. The methanol extracts of BMP bark were evaluated for their total antioxidant activity and ability to counteract inflammation induced by lipopolysaccharide (LPS) in RAW 264.7 macrophages. Among the 15 bark extracts from BMP, Albizia odoratissima (A. odoratissima), Engelhardia spicata (E. spicata), and Shorea robusta (S. robusta) showed the highest total phenolic contents and total antioxidant capacity by effectively scavenging free radicals. In particular, these three bark extracts significantly reduced the mRNA expression of LPS-induced inflammatory cytokines and enzymes inducible by inflammation in macrophages. Also, the mRNA expression of NADPH oxidase 2 was significantly suppressed by the three bark extracts in LPS-induced RAW 264.7 macrophages. These results suggest that out of the 15 bark extracts obtained from medicinal plants in Bangladesh, the extracts from A. odoratissima, E. spicata, and S. robusta exhibit substantial total antioxidant capacity by efficiently scavenging free radicals and also inhibit LPS-induced inflammation in macrophages.

토복령은 우수한 항균, 항산화, 항염증 효능을 가진 소재로 알려져 있다. 이러한 토복령(Smilax china)의 추출물의 기능성을 화장품에 적용하기 위한 기초연구로써 토복령에서 발견되는 플라보노이드인 quercetin, catechin, naringenin의 농도별 경피 투과 특성을 조사할 필요성이 있다. Marzulli의 정의에 적 용한 결과 케르세틴의 Kp 값은 0.1 mg/mL에서 "빠름"으로 분류되었고, 0.2 및 0.4 mg/mL에서 "보통"으로 분류되었다. 특히, 농도가 증가함에 따라 투과 속도가 감소하는 경향이 있었다. 나린제닌의 경우 Flux 값은 각각 0.1, 0.2 및 0.4 mg/mL 농도에서 0.69, 1.07 및 1.42 μg/hr/cm²이었으며, 해당 Kp 값은 각각 6.95, 5.34 및 3.56이었다. 나린제닌의 Kp 값은 모든 농도에서 "보통" 범주에 속하며, 케르세틴과 관찰된 것과 같이 농도가 높아짐에 따라 투과 속도가 감소하였다. 카테킨의 경우 Flux 값은 각각 0.1, 0.2 및 0.4 mg/mL 농도에서 0.75, 1.09 및 1.66 μg/hr/cm²이었으며, 해당 Kp 값은 각각 7.55, 5.46 및 4.16이었다. 카테킨의 Kp 값은 모든 농도에서 일관되게 "보통"으로 분류되었다. 여드름 저해능 및 항염증 효능이 우수 한 토복령 추출물의 유효성분인 quercetin, catechin, naringenin의 경피 투과 특성이 보통 이상으로 나타나 기능성 화장품에 사용할 수 있는 우수한 천연물 소재인 것을 확인할 수 있었다.

충청남도농업기술원 화훼연구소에서 2021년에 개발된 ‘Pinky Lang’은 분홍색 홑꽃 타입의 스프레이 국화 신품종 이다. ‘Pinky Lang’은 2016년 10월에 육종 하우스 내에서 2016년에 순백색의 진한 녹심이 매력적인 품종으로써 선발 된 백색 홑꽃의 ‘Bodre’ 품종을 방임 수분하여 48개의 종자 를 채취했다. 채취한 종자를 2017년 파종한 뒤 우수개체로 선발되어 2017년부터 2020년까지 4년간 촉성, 억제, 자연개 화 작형별 주년생산성 검정을 수행하여 선발된 우수계통을 ‘SP17-425-01’이라 계통명을 부여하였다. 2020년 최종적으 로 우수한 계통으로써 평가 및 심의를 받은 뒤 ‘충남SP-68 호’로 명명하였고, 당해 년도 12월 직무육성 신품종 선정위원 회를 통과하여 품종명은 ‘Pinky Lang’으로 하였다. ‘Pinky Lang’은 고온기에 화색이 변하지 않고 녹심이 매우 진하며 줄 기가 튼튼한 품종이다. 여름철 흰녹병에도 강하여 고온기 수출 품종으로 적합하다고 판단되었다. ‘Pinky Lang’은 연중 3 작기 재배테스트에서 단일처리 후 개화소요일수는 자연개화 작형 52일, 촉성작형 49일, 억제작형 50일이었고, ‘Yes Luna’ 는 각각 51일, 52일, 52일로 전반적으로 개화소요일수가 짧 았다. ‘Pinky Lang’의 절화장과 줄기굵기는 각각 104.5cm, 4.71mm으로 ‘Yes Luna’가 109.5cm, 4.25mm인 것에 비 해 5cm정도 짧았고 줄기굵기는 0.46mm 더 굵었다. ‘Pinky Lang’의 꽃 크기는 5.6cm이고 ‘Yes Luna’는 6.8cm로 1.2cm 작았다. ‘Pinky Lang’의 한 줄기에 달리는 꽃의 수와 한 송이 당 꽃잎수는 각각 27.7개, 30.9매였고, ‘Yes Luna’ 는 각각 18.0개, 37.0매인 것으로 착화수는 9.7개 많았고 꽃 잎수는 6.1매 적었다. 여름철 재배테스트를 통해 확인해본 결 과 흰녹병 저항성이 높은 경향을 확인하지만, 1~10% 정도의 병반을 보여 완전저항성을 가지진 못하는 것으로 사료된다. 자연개화 작형에서 절화수명의 경우는 24.5일로 ‘Yes Luna’ 에 비해 2.1일 길었다. ‘Pinky Lang’은 과습한 경우 줄기가 연약해질 수 있기 때문에 생장억제제인 Daminozide를 처리 하여 줄기를 강건하게 하고 절화 품질의 균일도를 높여 고온 기 재배에 안정적인 생산이 가능하여 수출할 수 있다.

In 2006, Cambodian Agriculture Research and Development Institute (CARDI) bred a high-quality tomato ‘Neang Pich’ variety. Since ‘Neang Pich’ is susceptible to Sclerotium rolfsii (S. rolfsii), it is severely affected the production major tomato growing regions. This study was conducted to evaluate the effect of seven S. rolfsii tolerant rootstocks on growth and yield in graft cultivation of ‘Neang Pich’ tomato. ‘Neang Pich’ seedlings were used as scion and non-grafted control. Six eggplant genotypes (‘2017053’, ‘2017062’, ‘17CJVC2’, ‘No. 80’, ‘VI041979A’, ‘VI041996’) and a commercial tomato variety (‘Hulk’) were used as rootstock. The grafted and non-grafted tomatoes were grown in a plastic greenhouse and open field. The survival rate of plants did not differ between plastic greenhouse (80.2%) and open field (79.5%). The top and root fresh weight of plants grown in a plastic greenhouse increased by 77% and 11% compared to the open field and the dry weight increased by 48% and 10%, respectively. The top (309 g) and root (18.9 g) fresh weight, and the top (90.5 g) and root (6.39 g) dry weight depending on rootstock were the highest in plants grafted onto ‘2017062’. The yield of tomatoes in a plastic greenhouse (19.5 MT/ha) was 65% higher than that of open field (11.8 MT/ha). The yield of tomatoes depending on rootstock were the highest in ‘2017062’ (17.8 MT/ha). The effect of cultivation practice and grafting on pH and sugar content (oBrix) of the fruit was non-significant difference (p0.05). The scion diameter, top fresh weight, fruit weight and yield (MT/ha) were significant difference (p0.05) in the interaction effect between tomato cultivation practices (plastic greenhouse and open field) and rootstock.
