This study investigated the wetland plant community in Mije Reservoir, Gunsan City, during September and October 2024, emphasizing its ecological significance as a primary producer and habitat provider within agricultural reservoir ecosystems. The reservoir was divided into 14 distinct sectors to comprehensively assess spatial plant distribution patterns. Aquatic plants were sampled using collection anchors deployed at the water’s edge, while hygrophytes and emergent macrophytes were surveyed along transects extending from the water’s edge to the embankment. A total of 192 vascular plant species were identified, of which 73 were classified as wetland plant species, encompassing diverse life forms: 36 hygrophytes, 17 emergent macrophytes, 6 floating-leaf species, 3 free-floating species, and 11 submerged species. Notably, the survey documented the presence of two endangered species, Euryale ferox and Cicuta virosa, alongside eight invasive alien plant species. A comparative analysis with a prior survey conducted in 2008 revealed a substantial increase of 54 wetland plant species. Currently, Mije Reservoir is subject to intensive aquatic plant removal management due to observed excessive proliferation and cyanobacterial bloom. However, the presence of endangered species underscores the critical need for a more nuanced reservoir vegetation management strategy that integrates the spatial distribution and conservation status of these ecologically important wetland plants.

Component-specific information is crucial for identifying sources of PM2.5 in indoor environments. However, profiles of PM2.5 at various locations, including subway tunnels are limited. This study aimed to evaluate the relationships between PM2.5 and its component across tunnels, platforms, and outdoor environments at underground subway stations in Incheon. The study was conducted at six underground subway stations in Incheon. PM2.5 concentrations were measured twice at each station, simultaneously covering the tunnel, platform, and outdoor areas. Carbon (two types), ion (eight types), and metal components (20 types) were analyzed using each analytical instruments. The mean PM2.5 concentration in the tunnel was 33.0±15.7 μg/ m3, significantly higher than the concentrations observed on the platform (12.9±4.6 μg/m3) and outdoors (13.1±7.6 μg/m3). The proportion of total metal concentrations in PM2.5 was highest in the tunnel (57.8%), followed by the platform (22.2%) and outdoor areas (11.3%). Significant correlations between the platform and tunnel were observed for organic carbon, SO4 2–, NO3 –, NH4 +, Ba, Mn, Fe, and Se. Significant correlations between the platform and outdoor were observed for SO4 2–, NO3 –, NH4 +, and Ti, while the tunnel and outdoor showed correlations for SO4 2– and NH4 +. PM2.5 concentrations and total metal concentrations were highest in the tunnel. While PM2.5 concentrations on the platform and outdoors were similar, total metal concentrations were higher on the platform than outdoors. From the platform’s perspective, the concentrations of Ba, Mn, Fe, and Se were only associated with the tunnel, while SO4 2–, NO3 –, and NH4 + had tendency of correlations between both the tunnel and outdoors. The findings suggest that for platform PM2.5 concentrations, Ba, Mn, Fe, and Se may serve as indicators of tunnel-originating PM2.5, while SO4 2–, NO3 –, and NH4 + may serve as indicators for outdoor sources.

To optimize initial cooling conditions, forced-air cooling was applied to freshly harvested oak mushrooms at 2 levels (0oC for 30 minutes, at 0oC for 1 hour) followed by room cooling at 3 levels (-3oC for 1 day, 0oC for 1 day, 3oC for 1 day). After initial cooling, the oak mushrooms were packaged with PVC film, then held in a storage room at 1oC for 6 weeks. Quality characteristics and percentage marketability were then investigated. As a control, Mushrooms were placed in storage with no initial cooling. The quality factors impacting marketability of fresh oak mushrooms were color change and appearance of decay. Off-odor did not occur or developed only slightly, so it did not affect oak mushroom quality within 6 weeks of low temperature storage. In all treatment groups, the shelf life in which 100% marketability was maintained was up to 3 weeks. At week 5, percent marketability of the 3 treatment groups 1 hour room cooling treatment at 0°C, 1 hour forced air cooling, and control was 100%. 80% In the group that underwent 30 min forced air cooling retained 80% marketability, and the group exposed to 1 day in room cooling at -3oC retained 86.7% marketability. At week 6 of 1oC storage, the marketability ratio was 80% in the 1 day room cooling at 0oC group, 66.7% in the 1 day room cooling at 3oC group, 46.7% in the 1 hour forced air cooling group, and 33% or less in all other treatment groups. Therefore, the most suitable initial cooling parameter to extend shelf-life of oak mushrooms is 1 day of in room cooling at 0oC immediately after harvest.

This study examined the physicochemical properties of radish pickle containing different natural preservatives (grapefruit seed extract, green tea extract, rosemary, or olive) stored for 0, 1, 2, 3, and 4 weeks. The hardness and color of the radish pickles with the grapefruit seed extract was higher than the other radish pickles during storage from week 0 to week 4. A 14.52% and 13.80% decrease in hardness and color were observed in the radish pickles with grapefruit seed extract (GFE), respectively. In addition, the total phenolic content was highest in the GFE in natural preservatives. Based on the results, GFE was selected as the optimal natural preservatives, and the growth of total viable bacteria and yeast were evaluated. The total viable bacteria and yeast showed similar patterns to the control. These results are expected to be useful in producing radish pickles with optimal quality and contribute to the development of various foods in the food industry.

The most important thing to successfully restore an oak forest is finding suitable climatic conditions and topographic factors for the oak species to be introduced. In this study, in order to find suitable environmental conditions for the five dominant oak trees on the Korean Peninsula, we carried out analysing the information on the location of forest vegetation on the Korean Peninsula. The range of annual mean temperature of the five oak trees was narrow in the order of Q. mongolica (7.7~14.3°C), Q. variabilis (9.2~13.8°C), Q. acutissima (10.5~14.3°C), Q. serrata (11.4~13.7°C), Q. aliena (11.0~12.9°C). The range of annual precipitation of oaks was narrow in order of Q. mongolica (1072.7~1780.9 mm), Q. variablis (1066.6~1554.9 mm), Q. acustissima (1036.5~1504.8 mm), Q. serrata (1062.6~1504.7 mm). The range of altitude was in order of Q. mongolica (147~1388 m), Q. serrata (93~950 m), Q. variabilis (90~913 m), Q. acustissima (60~516 m), Q. aliena (55~465 m). The range of slope was in the order of Q. mongolica (8~56°), Q. variabilis (5~52°), Q. serrata (11~45°), Q. aliena (15~38°), Q. acustissima (16~37°). These results are considered to be very useful in the case of ecological restoration using deciduous oak trees on the Korean Peninsula.

A method using liquid chromatography-tandem mass spectrometry (LC-MS/MS) was developed for neonicotinoid pesticide analysis in agricultural products. Four compounds (imidacloprid, clothianidin, acetamiprid, thiacloprid) were extracted with acetonitrile from agricultural products and cleaned up by NH2 solid-phase extraction procedure, and eluted with 0.1% formic acid in methanol/dichloromethane (5/95, v/v). The limit of detection and quantification were 0.0001-0.0005 mg/kg and 0.001 mg/kg, respectively. The mean recoveries of neonicotinoid pesticide from agricultural products were in the range of 90.7-100.9% and 94.4-99.8%, as spiked at 0.2 mg/kg and 0.02 mg/kg, respectively. This validation satisfied the national criteria for pesticide analytical methods. In summary, The present method is fast, precise and sensitive enough for the Positive List System (PLS), and we conclude that the method is also suitable for neonicotinoid pesticide determination in a wide range of agricultural products.

We compared and analyzed the astronomy terms currently used by astronomers in the two Koreas to promote inter-Korean astronomy cooperation. We analyzed a total of 2716 pairs of terms common in both Koreas glossaries, using the astronomical terminology contained in the South Korean source, the ‘Terminology of Astronomy’, and the North Korean source, ‘Mirror 2.0’. For each pair of terms, their morphological features and meanings were compared. We categorized into 11 groups for comparison of astronomical terms. We found that most of the terms are used similarly in the two Koreas. About 47% of the total is similar in form. Although terms are different, meanings communicate about 37% of the total. As a result, similar terms used by the two Koreas correspond to about 85% of the total. However, 15% of terms are difficult to understand because they have different forms or meanings such as diffraction (회 절/에돌이), flare (플레어/요반) etc. Further research on terms that are used differently by the two Koreas, and the conversion of appropriate terms through mutual understanding should be made in the future.

물거미는 한국에서 유일하게 연천군 은대리의 좁은 습지에서만 제한적으로 분포하고 있다. 이 연구에서는 물거미 개체군에 영향을 주는 서식 환경요인을 규명하기 위하여 습지내 물거미의 개체수와 수생태계의 다양한 물리화학 및 생물학적 환경요인과의 관계를 조사하였다. 그 결과 물거미의 개체수는 서식지의 물리화학적 환경요인 중에서 습지의 면적이 좁고 암모니아태질소와 전기전도도가 높을수록 증가하였다. 물거미는 포식자나 먹이인 피식자와는 관련성이 낮고 왕우렁이의 개체수가 많을수록 감소하였다. 또한 정수식물의 피도와는 관련성이 없었으나 부엽식물의 피도가 높을수록 물거미수는 감소하였고, 그 반대로 침수 식물의 피도가 높을수록 이에 비례하여 물거미 수는 증가 하였다. 이러한 결과는 물거미의 서식환경에서 수생식물이 중요하게 관련됨을 의미하고, 현재 이 서식지에서 외래종인 왕우렁이는 수생식물의 최대 섭식자로 작용하고 있으므로 이에 대한 제어대책이 시급히 필요하다.
