온실 내부 환경은 지역에 따라 외부 환경의 영향을 지속적으로 받는다. 본 연구는 몽골, UAE(아부다비), 호 주(퀸슬란드) 등 지역별로 구축된 한국형 스마트 온실의 환경 특성을 비교하고자 수행하였다. 몽골과 아부다비의 온실 모두 내외부 엔탈피 차이가 감소함에 따라 환기율이 증가하였다. 아부다비의 반밀폐형 온실에서는 10시부터 14시까지 평균 내부 기온이 외부 기온보다 약 7－10°C 낮았고 내부 VPD(12mbar)는 외부 VPD(56mbar)보다 4.6 배 낮았는데 이 결과는 포그 시스템 운영과 관련이 있는 것으로 보인다. 퀸즐랜드 온실의 경우, 내부 온도가 외부 온 도보다 11시 기준 약 3.81°C 높았고, 내부 엔탈피와 VPD가 외부 온도보다 높았으며, 내부와 외부의 엔탈피 차이가 증가함에 따라 환기율이 증가하였다. 이 결과로 엔탈피를 낮추는 것은 환기와, VPD를 낮추는 것은 포그 시스템 작 동과 관련이 있는 것을 알 수 있다. 또한, 작물 생육에 적합한 환경 조건을 효과적으로 관리하기 위해 엔탈피와 VPD 기반의 포그, 환기 또는 난방 시스템이 필요하다는 것을 알 수 있다.

Background: The increasing demand for real-time professional fitness coaching has led to a need for accurate exercise posture recognition using artificial intelligence. Objectives: To compare the performance of Feedforward Neural Network (FNN) and Stacked Long Short-Term Memory (LSTM) models in classifying fitness posture images using detailed joint coordinate labeling. Design: Comparative analysis of machine learning models using a labeled dataset of fitness posture images. Methods: A dataset from AI-hub containing images and data of 41 exercises was used. Five exercises were selected and processed using a custom program. Data was converted from JSON to CSV format, augmented with joint condition information, and analyzed using Google Colab. Results: The best FNN model achieved a training error of 1.21% and test error of 9.08%. The Stacked LSTM model demonstrated superior performance with a training error of 1.05% and test error of 6.09%. Conclusion: Both FNN and Stacked LSTM models effectively classified sequential fitness images, with Stacked LSTM showing superior performance. This indicates the potential of Stacked LSTM models for accurate fitness posture classification in real-time coaching scenarios.

The recent release of contaminated water from the Fukushima Daiichi Nuclear Power Plant highlights the need for accurate tritium measurement, particularly near the minimum detectable activity (MDA) of 5 Bq·L−1 set by South Korea’s Nuclear Safety and Security Commission. This study aims to improve low-level tritium measurement accuracy by optimizing the region of interest (ROI) for quench curve determination. These adjustments are crucial for separating tritium signals from background noise. Quench standards were prepared and measured using a liquid scintillation counter (LSC). Three ROIs were analyzed to assess the impact of channel selection on measurement precision: A 20-148 channel range optimized via figure of merit (FOM) analysis, a 20-250 channel range covering tritium’s full beta spectrum, and a broad 1-1024 channel range. Quench curves were obtained by fitting the counting efficiency of each ROI to the quench standards. Tritium samples with six different activity levels were prepared, and their radioactivity was calculated using the quench curves. Selecting appropriate ROIs for quench curve determination is critical for measuring low-concentration tritium accurately. This approach reduces uncertainty and emphasizes reliable methods to improve the precision and consistency of tritium measurements.

Industries that use or produce radionuclides have unintentionally released these substances into surrounding soils and sediments. To address this problem, Beautiful Environmental Construction (BEC) Co. developed the BEC’s Radioactive Soil Decontamination (BERAD) system to remove contaminants and reduce the volume of radionuclide-contaminated soils. Owing to the limited availability of radioactive isotopes such as 60Co, 90Sr, 137Cs, and uranium-contaminated soil, naturally occurring elements in soil were used in this demonstration. The soil was divided into six size fractions via manual wet sieving and the BERAD system. Then, the concentrations of uranium, cobalt, strontium, cesium, and iron in each fraction were measured. The results of both separations showed that a considerable amount of each element is retained in the finer size fractions (<0.2 mm). After BERAD separation, the corresponding values yielded 53% uranium, 45% strontium, 66% cobalt, and 53% cesium in the fine size (<0.2 mm) fractions of 35% by weight. The study found that the concentrations of these elements increased as the particle sizes decreased. Iron and micaceous minerals played a significant role in retaining the elements. The pilot scale BERAD system yielded results that were similar to those obtained via laboratory wet-sieving and was successfully demonstrated as a soil washing technology.

Pluripotent stem cells (PSCs) are undifferentiated cells with the potential to develop into all cell types in the body. They have the potential to replenish cells in tissues and organs, and have unique properties that make them a powerful tool for regenerative therapy. Embryonic stem cells (ESCs) derived from the inner cell mass of the blastocyst of pre-implantation embryo and epiblast stem cells (EpiSCs) derived from the epiblast layer of post-implantation embryo are the well-known PSCs. These stem cells can differentiate into any of three germ layers of germ cells (endoderm, mesoderm and ectoderm). Additionally, induced pluripotent stem cells (iPSCs) refer to adult somatic cells reprogrammed to return to the pluripotent state by introducing specific factors. This is a breakthrough in stem cell research because ethical concerns such as fertilized embryo destruction can be avoided. PSCs have tremendous potential in treating degenerative cells by generating the cells needed to replace damaged cells, which can also allow to generate specific cell types to study the mechanisms of the disease and create disease models that screen for potential drugs. However, if the proliferative capacity of PSCs is not controlled, there is a risk that tumors will form, as this can lead to uncontrolled growth in their proliferative capacity. In addition, when PSCs are used for therapeutic purposes, there is a risk that the body’s immune system rejects the transplanted cells when the transplanted cells do not originate from the patient’s own tissue. Taken together, PSC is the foundation of stem cell research and regenerative medicine, providing disease treatment and animal development understanding. We would like to explain the classification of PSCs based on their developmental potential, the types of PSCs (ESCs, EpiSCs and iPSCs), their pluripotent status (naïve vs. primed) and alkaline phosphatase (AP) in PSCs and PSCs in domestic animals.

기후변화로 인해 국내에서의 기온, 강수량, 호우일수가 증가 할 것으로 예측됨에 따라, 토양 답압과 높은 불투수면적 비율이 나타나는 도심지를 중심으로 정원과 공공녹지에 활용되는 식물 소재에 있어 내침수성이 중요한 특성으로 부각될 가능성이 높 다. 그러나 내침수성 식물소재에 대한 대다수의 문헌은 재배경 험이나 각 종의 서식지 환경에 기반하고 있는 경우가 많아 실험 적 검증이 필요하다. 따라서 본 연구는 토양수분함량이 높은 서식지에서 기원한 골등골나물(Eupatorium lindleyanum DC.), 새등골나물(E. fortunei Turcz.), 좀개미취(Aster maackii Regel) 3개 종과 중간인 서식지에서 기원한 까실쑥부쟁이 (A. ageratoides Turcz.) 1개 종의 침수조건에 대한 생육반응 비교로 서식지 환경이 내침수성 평가의 유효한 지표인지 알아보 고자 하였다. 실험대상 종을 6주간 무처리(대조구), 5일 침수처리, 7일 침수처리한 결과, 골등골나물과 새등골나물은 대조구와 처리구간 생육반응에서 유의한 차이가 관찰되지 않아 높은 수준 의 내침수성을 지니는 것으로 나타났다. 좀개미취는 생장반응이 처리구에서 대조구 대비 유의하게 감소하여 내침수성은 제한적 인 것으로 보였으나, 5일 침수처리구에서 광계 II의 최대양자효 율(Fv/Fm)이, 두 처리구 모두에서 지상부 대비 지하부의 비율 (R/S율)이 대조구와 유의한 차이를 보이지 않아 침수조건의 해 소 후 회복 가능성을 지니는 것으로 나타났다. 까실쑥부쟁이는 처리 4 주차에 모든 처리구에서 100%의 고사율을 보여 내침수 성을 갖추지 못한 것으로 판단되었다. 결론적으로, 서식지 환경 은 내침수성과 관련이 있다 할 수 있었으나, 내침수성의 정확한 평가를 위해서는 토양수분함량 외 다양한 환경요소들을 함께 고려해야할 필요성이 있을 것으로 보인다.

Ectopic ureter refers to a congenital anomaly in which one or both ureters do not connect to the urinary bladder at the correct anatomical site. This case report discusses the case of a 6-year-old female mixed-breed dog diagnosed with chronic urinary incontinence, systemic hypertension, pancreatitis, and sepsis resulting from an ectopic ureter. Treatment involved an initial nephro-ureterectomy to address severe pyonephrosis, followed by ureteroneocystostomy for the remaining functional kidney. Post-surgical outcomes showed notable improvements in clinical symptoms, laboratory findings, and blood pressure. This report emphasizes the need for early diagnosis and appropriate surgical treatment in cases of ectopic ureter. Additionally, it aims to present the clinical symptoms and conditions resulting from prolonged disease progression, as well as the corresponding treatment methods and prognosis.

This study aimed to evaluate the effectiveness of a zeolite and sulfuric acid mixture (ZS) as an air filter to mitigate the emissions of ammonia (NH3), nitrous oxide (N2O), and methane (CH4) during the composting of cattle manure. Compared to the control group (blank), ZS reduced NH3 emissions by 91.4%, N2O emissions by 33.6%, and CH4 emissions by 20.0% over the 100-day composting period. Additionally, sulfuric acid in the ZS reacted with NH3, storing it as ammonium sulfate [(NH4)2SO4], which can serve as a source of nutrients such as nitrogen (N) and sulfur (S). To evaluate the fertilizing efficiency of [(NH4)2SO4] in ZS for maize growth, we applied four treatments: control (non-N fertilizer), collected ZS (cZS), cattle manure (organic fertilizer, OF), and urea (chemical fertilizer, CF). Compared to the control, cZS increased total dry weight (DW) by 48%, total digestible nutrients (TDN) by 7.3%, and crude protein (CP) by 77.8%. No significant differences were found among the applications of cZS, OF, and CF. These results suggest that the zeolite mixed with sulfuric acid effectively reduces hazardous gas emissions such as NH3, CH4, and N2O during cattle manure composting. Furthermore, the collected zeolite can potentially be reused as fertilizer, suggesting a positive opportunity for resource recycling to mitigate environmental pollution.

갯취(Ligularia taquetii)는 국화과에 속하는 한반도 특산식물 로, 관상가치가 뛰어나지만 한국 관속식물 적색목록에서 취약종 (VU)으로 분류되며 보존이 필요한 종이다. 본 연구는 갯취 종자 의 휴면 유형을 분류하고, 후숙 처리 효과를 확인하여 보존을 위한 기초 자료를 제공하고자 하였다. 2022년과 2023년에 채종한 종자를 사용하여 온도, 저온 습윤, GA3, 후숙 처리 실험을 진행하였다. 갯취 종자는 수분을 원활하게 흡수하였고, 모체에 서 탈리될 때 배가 형태적으로 완전히 발달한 상태였다. 4, 15/6, 20/10, 25/15℃에서 배양한 결과, 4주간 발아하지 않았 기 때문에 생리적 휴면(physiological dormancy, PD)으로 분 류하였다. 후숙 처리를 하지 않거나 6주간 후숙 처리만 한 종자 의 발아율은 20% 미만이었으나, 후숙 처리 후 8주 동안 저온 습윤 처리한 종자의 발아율은 70%로 증가하였다. 또한, 후숙 처리 후 GA3 100 mg·L⁻¹ 농도 처리 시 49% 발아하였다. 따라 서, 갯취 종자의 PD를 타파하기 위해 후숙 후 저온 습윤 또는 GA3 처리가 효과적인 것으로 보인다.

Background: Pluripotent stem cells (PSCs) are capable of differencing into various cell types in the body, providing them valuable for therapy of degenerative diseases. Patientspecific treatments using PSCs, such as mesenchymal stem cells in patient’s own body, may reduce the risk of immune rejection. Inducing the differentiation of PSCs into vascular endothelial cells (ECs) altering culture conditions or using specific growth factors is able to applied to the treatment of vascular diseases. The purpose of this study was to induce the differentiation of porcine epiblast stem cells (pEpiSCs), bone marrow-derived mesenchymal stem cells (pBM-MSCs) and adipose-derived mesenchymal stem cells (pAMSCs) into ECs and then examine the functionality of vascular ECs. Methods: Porcine pEpiSCs, pBM-MSCs and pA-MSCs were induced to differentiate into ECs on matrigel-coated plates in differentiation medium (EBM-2 + 50 ng/mL of VEGF) for 8 days. Cells differentiated from these stem cells were isolated using CD-31 positive (+) magnetic-activated cell sorting (MACS) and then proliferated in M199 medium. Evaluation of ECs differentiated from these stem cells was treated with capillary-like structure formation and three-dimensional spheroid sprouting assay. Results: Porcine pEpiSCs, pBM-MSCs and pA-MSCs showed similar expression of pluripotency-related genes (OCT-3/4. NANOG, SOX2). These stem cells were differentiated into vascular ECs, but showed different morphologies after the differentiation. Cells differentiated from pEpiSCs showed an elongated spindle-like morphology, whereas cells differentiated from pBM-MSCs showed a round pebble-like morphology. In the case of pA-MSCs, these two morphologies were mixed with each other. Additionally, vascular ECs differentiated from these stem cells showed different formation of capillary-like structure formation and three-dimensional spheroid sprouting assay. Conclusions: Cells differentiated from pEpiSCs, pBM-MSCs and pA-MSCs presented the functionality of different vascular ECs, demonstrating the potential of the excellent ECs differentiated from pEpiSCs.

Airpower plays a key role in neutralizing military threats and securing victory in wars. This study analyzes newly introduced fighter forces by considering factors like performance, power index, operational environment, airbase capacity, survivability, and sustainment capability to devise an optimal deployment strategy that enhances operational efficiency and effectiveness. Using optimization methods like mixed integer programming (MIP), the study incorporates constraints such as survivability and mission criticality. The focus is on major Air Force operations, including air interdiction, defensive counter-air, close air support, and maritime operations. Experimental results show the proposed model outperforms current deployment plans in both wartime and peacetime in terms of operations and sustainment.

This study presents an optimization model for the Tactical Information Communication Network (TICN), which is crucial for military operations, focusing on the efficient deployment of communication nodes to create a rapid and robust network while minimizing both distances and the number of nodes required. By integrating mixed integer programming (MIP) with minimum spanning tree (MST) and Steiner Tree algorithms, the model ensures that nodes are connected through the shortest, most efficient routes. Simulations demonstrate the model’s ability to form cohesive networks under constrained resources and time, reducing transmission distances and maintaining network stability. Case studies in a grid environment confirm the system's efficiency, with the model able to redeploy nodes if damaged to preserve network integrity. By utilizing both high- and low-capacity transmission systems, the model ensures reliable communication in challenging terrains like Korea’s mountainous landscape. The findings have critical implications for military communication strategies, especially for multi-domain operations involving air, land, and sea forces, and support decision-making for rapid and efficient deployment of communication networks in unpredictable conditions.

In this study, carbon coating was carried out by physical vapor deposition (PVD) on SiOx surfaces to investigate the effect of the deposited carbon layer on the performance of lithium-ion batteries as a function of the asphaltene content of petroleum residues. The petroleum residue was separated into asphaltene-free petroleum residue (ASF) and asphaltene-based petroleum residue (AS) containing 12.54% asphaltene by a solvent extraction method, and the components were analyzed. The deposited carbon coating layer became thinner, with the thickness decreasing from 15.4 to 8.1 nm, as the asphaltene content of the petroleum residue increased, and a highly crystalline layer was obtained. In particular, the SiOx electrode carbon-coated with AS exhibited excellent cycling performance with an initial efficiency of 85.5% and a capacity retention rate of 94.1% after 100 cycles at a current density of 1.0 C. This is because the carbon layer with enhanced crystallinity had sufficient thickness to alleviate the volume expansion of SiOx, resulting in stable SEI layer formation and enhanced structural stability. In addition, the SiOx electrode exhibited the lowest resistance with a low impedance of 23.35 Ω, attributed to the crystalline carbon layer that enhanced electrical conductivity and the mobility of Li ions. This study demonstrated that increasing the asphaltene content of petroleum residues is the simplest strategy for preparing SiOx@C anode materials with thin, crystalline carbon layers and excellent electrochemical performance with high efficiency and high rate performance.

The circular mitogenome of M. thunbergianae is 15,406 bp including 13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNAs. AT ratio is 78.2%. Maximum-likelihood and Bayesian inference phylogenetic trees show that M. thunbergianae is clustered with M. matsumurae, and family Margarodidae is clustered with family Pseudococcidae with enough supportive values.

Bio-efficacies of two different types of fungicides, Diniconazole and Paclobutrazol with their effects as plant g rowth regulators f or Kimchi Cab bage were e valuated o n February 4 to A pril 13, 2024 in Los Baños, Laguna, Philippines. The experiment was done during the off-season planting of Kimchi Cabbage in the country. Yield and other horticultural characteristics were observed for seven different groups: group 1, untreated control; group 2, recommended rate of granular fertilizer (RR-G); group 3, recommended rate of granular fertilizer plus recommended rate of Diniconazole; group 4, recommended r ate of D iniconazole (alone); g roup 5 , recommended rate o f Paclob utrazol (RR-PBZ), group 6, RR-G plus RR-PBZ; and group 7, RR-G plus ½ RR-PBZ. Results showed that combination of recommended rate of granular fertilizer plus the full recommendation of Paclobutrazol (group 6) resulted in a significantly higher yield of 64.9 tons/ha than other groups with yields ranging from 23.3 to 55.3 tons/ha. Such significantly higher yield in group 6 was also attributed to the number of leaves produced by plants at the time of harvest. Regarding effects of two chemical treatments, the combination of Diniconazole a nd P aclob utrazol a s recommended granular f ertilizers h elped in t he heading of K imchi Cabbage during hot conditions with an average temperature of 32-35°C from March to April at the heading stage plus a f actor of b eing planted a t a lowland area i n the country. T he a dvantage o f Paclobutrazol aside from yield is its availability in the country as compared to Diniconazole (Binnari).
