기후변화에 따른 관리형 화분매개자 부족은 온실 딸기 재배에서 대체 화분매개자의 필요성을 높이고 있다. 재래꿀벌(Apis cerana)은 양봉꿀벌 (Apis mellifera)의 대체종으로 제안되었으나, 온실 조건에서의 직접 비교 연구는 제한적이다. 본 연구에서는 2024년 11월부터 2025년 3월까지 대 한민국 충남 논산의 딸기 온실에 두 종의 봉군을 설치하고, 봉군세력, 먹이활동, 화분매개 효율을 모니터링 하였다. 두 종 모두 세력이 감소했으나, 양봉꿀벌에서 감소 폭이 더 컸다. 종 간 먹이활동 차이는 정오 무렵에만 나타났으며, 세력으로 보정하면 사라졌다. 꽃 방문 및 정상 수과 형성률로 측정한 화분매개 효율은 종 간 유의한 차이가 없었으나, 방문당 효율은 양봉꿀벌에서 다소 낮은 경향을 보였다. 화분매개 효율은 먹이활동과는 양의 상관을, 봉군 세력과는 음의 상관을 나타냈다. 이러한 결과는 재래꿀벌이 겨울철 봉군세력을 더 안정적으로 유지하면서도 유사한 화분매개 서비스 를 제공함을 보여주며, 온실 딸기 재배에서 대체 화분매개자로서의 잠재성을 뒷받침한다.

심비디움 ‘연두랑’은 절화용으로 적합한 연녹색 품종을 개발 하기 위하여 2023년 국립원예특작과학원에서 육성한 신품종 으로 2009년에 C. ‘Daijeolturuk’과 C.‘Romeo’를 인공교배 하다. 교배 후 기내파종과 하우스 순화를 통해 121개의 실생묘 를 얻었고, 그 중 형태적, 생리적, 개화 특성을 포함한 종합적인 특성을 바탕으로 우수한 2계통을 1차 선발하였다. 이후 선발계 통의 안정성과 균일성을 확인하기 위하여 2016년부터 2022년 까지 특성검정을 수행하였고, 최종적으로‘C09037-45’한 계통 을 선발하였고 ‘원교 F1-80’로 계통명을 부여한 후,‘연두랑’으 로 명명하였다. 본 품종은 67.2 cm 길이의 직립성 화경에 약 22개의 연녹색 꽃을 착화하는 중형종으로, 절화수명은 평균 34.3일로, 대비품종 ‘러블리킹’보다 6일 이상 길었다.‘연두랑’ 은 1월부터 개화하며 기내 증식력은 대비 품종과 유사한 정도 로 나타나 상업적 활용을 위한 대량 증식이 가능할 것으로 판단 된다.

In today’s project environment, significant changes are taking place, prompting a shift in project management knowledge from a traditional process oriented approach to one that is principle and performance based, allowing for more flexible application across diverse industry contexts. This study empirically examines the impact of four key knowledge areas from the PMBOK (Project Management Body of Knowledge) stakeholder management, planning management, project work management, and delivery management on both project performance and corporate performance. The research focuses on the construction industry as the target sector and additionally analyzes whether project size and company size function as moderating variables. The results indicate that a higher level of maturity in the key knowledge areas leads to improved project and corporate performance, with such positive effects being particularly pronounced in large scale projects and large enterprises. In the construction industry, in particular, the four knowledge areas were found to be closely associated not only with project performance but also with non-financial corporate performance indicators such as customer satisfaction, customer loyalty, and corporate image.

Between July 2024 and July 2025, we collected spleen samples from 119 wild rodents captured across various zoogeographical regions of Gwangju City, Republic of Korea, to screen for major zoonotic pathogens, including Anaplasma, Babesia, Bartonella, Borrelia, Coxiella, Ehrlichia, and Rickettsia species. Of these, 13 samples (10.92%) tested positive for Bartonella spp. The positive samples were cultured on blood agar, resulting in eight bacterial isolates. Internal transcribed spacer (ITS) gene sequencing and phylogenetic analysis confirmed all Bartonella-positive samples as B. grahamii. Antibiotic susceptibility testing revealed that all B. grahamii isolates exhibited multidrug resistance (MDR) to ciprofloxacin, nalidixic acid, cefoxitin, streptomycin, and tetracycline, and showed intermediate resistance to ampicillin. In contrast, the isolates were susceptible to ceftazidime, cefotaxime, ceftriaxone, imipenem, gentamicin, amikacin, azithromycin, chloramphenicol, and trimethoprim/sulfamethoxazole. These findings provide essential baseline data on the presence and resistance patterns of B. grahamii in wild rodent populations inhabiting peri-urban environments. The detection of MDR Bartonella strains underscores a potential public health concern, particularly regarding zoonotic spillover via ectoparasites such as ticks. Sustained molecular surveillance and antimicrobial resistance monitoring are warranted to mitigate future zoonotic threats.

Myxomatous mitral valve disease (MMVD) is the most prevalent cardiac disease in dogs worldwide. Left atrial enlargement is a prominent feature associated with an increased risk of congestive heart failure in dogs with MMVD. Left atrial anteroposterior diameter (LAD) has been suggested as a supplementary parameter for evaluating LA size in various species. The purpose of our study was to establish a correlation between the left atrial anteroposterior diameter normalized to body weight (LADn) and N-terminal pro-brain natriuretic peptide (NT-proBNP) in dogs with MMVD and to assess the diagnostic potential of LADn for MMVD. We conducted this study on 35 dogs and categorized them into the control and MMVD groups. The control group consisted of 10 dogs, whereas the MMVD group included 25 dogs classified into stages B1, B2, and C according to the American College of Veterinary Internal Medicine (ACVIM) guidelines. LADn was measured using echocardiography, and NT-proBNP levels were assessed using a fluorescent immunoassay. In conclusion, LADn shows promise as a valuable diagnostic marker of MMVD in dogs. The strong positive correlation between LADn and NT-proBNP levels demonstrates the usefulness of LADn as a clinical index for evaluating cardiac function and disease progression in dogs with MMVD.

Lumpy Skin Disease (LSD) and Foot-and-Mouth Disease (FMD) cause substantial economic losses on the livestock industry. Therefore, vaccinations have been implemented as the control strategy in endemic countries. However, the potential adverse effects of administering vaccines for both diseases simultaneously have not been thoroughly evaluated. The aim of this study was to assess the impact of vaccinating dairy cows with either or both LSD and FMD vaccines on milk production and physiological parameters such as milk temperature, rumination time and body weight. The experimental groups were divided into four according to the injection materials: 1) saline, 2) LSD vaccine, 3) FMD vaccine, and 4) both vaccines. The impact of vaccination on milk yield and physiological parameters was evaluated daily until 12 days post-vaccination, and milk components were analyzed twice, once per week. Among the experimental groups as well as each vaccine group, no statistically significant differences (p < 0.05) were observed at milk yield, milk components, or milk temperature. This suggests that simultaneous vaccination of LSD and FMD can be administered without adverse effects.

This study examines the impact of Strategic Emphasis (SE) on Enterprise Value (EV) in KOSDAQ 150 firms, exploring how the balance between Value Creation (VC) and Value Appropriation (VA) strategies influences Tobin's Q as a measure of EV across different industries. Using Mizik and Jacobson's Strategic Emphasis framework, this research conducted a panel regression analysis on financial and stock market data of KOSDAQ 150 firms over a decade (2014–2023). This study employed a comprehensive empirical framework that accounts for industry characteristics, firm profitability, and time effects to examine how different sectors respond to SE changes. The analysis revealed that SE significantly impacts EV, with varying effects across industries. For instance, VC strategies positively influenced EV in the Healthcare sector, whereas VA strategies proved more effective in the Consumer Discretionary sector. Additionally, the relationship between SE and EV was moderated by firm profitability and shaped by industry-specific factors. This study highlights the importance of choosing appropriate measures, such as Tobin's Q, when evaluating corporate strategies. The findings offer actionable insights for Korean venture firms, emphasizing that strategic resource allocation should be tailored to industry-specific dynamics and a firm’s financial context to maximize EV.
