This study analyzed the impact of improvements to the driver’s license system for elderly drivers on the incidence of traffic accidents. As South Korea’s population ages, the number of licensed drivers aged 65 years and older has surpassed 4.5 million as of 2024, accounting for approximately 15% of all license holders. Traffic accidents involving elderly drivers have increased steadily and tend to be more severe than those involving younger drivers. In response, the Road Traffic Act was amended in 2019 to shorten the license renewal cycle for drivers aged 75 and older, mandate dementia screening, and require traffic safety education. This study compared traffic accident statistics before and after the policy change (2018 and 2023) and used consulting data from 617 elderly drivers to examine the relationships between driving time, frequency, distance, and potential accident risk factors using a negative binomial regression analysis. The results show that after the policy changes, the number of traffic accidents per 10,000 elderly drivers decreased by up to 20.4%, demonstrating the effectiveness of the reforms. Furthermore, increased driving time, frequency, and distance were all significantly associated with a higher accident risk, whereas older age was linked to fewer accidents, likely owing to self-regulation among elderly drivers. Policy recommendations include limiting continuous driving time to 60 min, encouraging regular breaks, enhancing tailored safety education, tightening license aptitude test standards, and supporting the adoption of advanced safety features in vehicles. This study is expected to contribute to the development of effective policies to reduce traffic accidents among elderly drivers and create a safer traffic environment.

This study aimed to evaluate the nutritional composition of various edible and medicinal mushrooms and assess their potential as alternative food sources in response to increased meat consumption, which poses environmental and health risks. The crude protein, crude fat, carbohydrate, dietary fiber, and vitamin C contents of 17 edible and medicinal mushroom species, including Flammulina velutipes, Pleurotus ostreatus, Pleurotus eryngii, Agaricus bisporus, Lentinula edodes, and Wolfiporia extensa, were systematically analyzed. Pleurotus ostreatus‘Suhan 2’ and P. eryngii‘No. 2’ showed high crude protein and carbohydrate contents, suggesting excellent potential as alternative protein and energy sources. Flammulina velutipesvarieties ‘TO22’ and ‘Aram’ exhibited relatively high crude fat contents, whereas P. eryngii‘No. 2’ and P. ostreatus‘Suhan 2’ had high vitamin C levels, suggesting a beneficial role in immune enhancement. In contrast, the medicinal mushroom W. extensa had relatively low protein and dietary fiber contents, limiting its potential as an alternative protein source compared to the other edible mushrooms. Nonetheless, it may provide other health benefits. The present study provides foundational data for the utilization of mushrooms as sustainable alternative food resources, supporting efforts to mitigate environmental impacts of meat production and improve dietary health.

본고에서는 라틴아메리카의 저항음악 운동인 누에바 깐시온(Nueva Canción)의 형성과 전개, 그 것이 지닌 정치적 의미를 고찰하였다. 연구의 목적은 누에깐시온이 억압적 권력에 맞서 민중의 정체성과 연대를 형성하는 문화적 정치 실천으로 기능하였음을 밝히는 데 있다. 이는 이러한 음악 운동이 예술적, 정치적 관점에서 사회적 연대와 공동체 의식을 고양하는 데 기여할 수 있음을 시 사한다. 연구 범위는 칠레, 쿠바, 아르헨티나 등지에서 전개된 누에바 깐시온 운동의 다양한 양상 과 이를 통해 형성된 문화적·정치적 연대를 중심으로 설정하였다. 연구 방법으로 안토니오 그람 시의 헤게모니 이론과 레이먼드 윌리엄스의 문화 유형 개념을 이론적 틀로 삼아 민속음악이 억압 적 체제 속에서 어떻게 저항의 수단으로 작용하였는지 살펴볼 수 있었다. 민속음악을 통해 각국의 민족적 정체성을 강화하며 음악이 대중과의 감정적 유대를 형성하고 이를 바탕으로 정치적 실천의 장으로 기능한 과정을 분석하였으며 빅토르 하라와 1973년 칠레 군사 쿠데타를 대표적인 사례로 삼아 음악이 사회적 변화와 저항의 도구로 작용할 수 있음을 조명하였다. 연구 결과 누에바 깐시 온은 위로부터의 음악에 대응하는 아래로부터의 음악으로서 문화적 헤게모니에 균열을 내고 초국 가적 연대를 이룬 중요한 음악 운동임을 확인하였다. 본 연구는 음악이 예술의 기능을 넘어 집단 기억과 공동체 정체성을 형성하는 중요한 도구가 될 수 있음을 강조하며 오늘날에도 여전히 유효 한 사회적 메시지를 전달하는 음악 운동으로서의 가능성을 보여주었다.

Sixty dried agricultural products were collected from February to July 2024. Among these, 16 samples were randomly purchased from large supermarkets and local markets in Gwangju, and 44 were obtained from online marketplaces. Only products labeled with phrases such as “No Food Additives” or “100% Raw Ingredients” were selected for analysis. The aims of this study were to determine the concentrations of sulfur dioxide, preservatives, artificial colorants, and toxic heavy metals (lead and cadmium) in dried agricultural products, assess their risk indices, and provide foundational data to establish relevant regulatory standards. The results revealed that sulfite compounds were detected in some samples, with the highest sulfur dioxide concentrations found in gourds (82.99- 1046.95 mg/kg), apricots (10.87-529.45 mg/kg), and konjac powder (23.59-475.92 mg/kg). The highest sulfur dioxide risk index was observed in persimmons, with values ranging from 4.74% to 16.61% for male and 6.26% to 26.84% for female consumers. Sweet potatoes followed, with risk index values of 6.87% and 11.29% for male and female consumers, respectively. All the samples exhibited sulfur dioxide risk indexes below 100%, indicating safety. No preservatives or artificial colorants were detected in any of the samples, suggesting that sulfites can be used as alternatives to preservatives in certain products. The concentrations of lead in dates (9.55-137.09 μg/kg) and gourds (10.76-49.14 μg/kg) and cadmium in gourds (16.36-51.76 μg/kg) were within safe limits, with risk indexes below 100%. This study provides crucial baseline data for evaluating the safety of dried agricultural products. Furthermore, it underscores the need for more comprehensive risk assessments that consider the interactions between sulfur dioxide, heavy metals, and consumption patterns. Lastly, it highlights the necessity of strengthening regulatory standards to better protect consumers.

Purpose: This study was aimed to explore and analyze the experiences of nurses regarding department transfers following the sudden closure of a ward due to the collective resignation of residents. Methods: Data were collected from November 1 to 29, 2024, and a qualitative content analysis was employed. The participants were 11 nurses who were transferred to different departments following a ward’s sudden closure owing to the residents’ collective resignation. Results: A total of six themes and 24 sub-themes were identified. the first theme is ‘After the resident left, the ward was closed’. The second theme is ‘Various job placements were assigned after the ward’s unfortunate closure’. The third theme is ‘Difficulty adjusting to the new environment and leaning to adapt’. The fourth theme is ‘Changes in the nurse-physician relationships’, and the subtheme is ‘Surprised by doctors seeking nurses' opinions due to the absence of residents. The fifth theme is ‘Become an expert at adapting’. The sixth theme is ‘Worries about the future and a faint glimmer of hope’. Conclusion: This study highlights the challenges nurses encountered in adjusting to new departments following the unprecedented mass resignation of residents and the ensuing ward closure. Nurses initially faced difficulties, feeling expendable in the new environment. However, through the support and collaboration of their colleagues, they demonstrated resilience and adapted effectively. The study also noted that, despite the absence of residents, direct communication between medical staff and patients continued to function smoothly, facilitating their involvement in treatment planning alongside specialists and professors. Although departmental transfers can lead to increased job stress for nurses, successful adaptation during these transitions fosters professional growth by enhancing their knowledge, skills, and influence. Furthermore, knowledge sharing among nursing staff contributes to the overall development of the organization. To promote both personal growth and organizational advancement, nursing managers must actively listen to nurses’ perspectives about departmental transfers and provide compassionate support to assist in their adaptation. Creating an organizational culture that recognizes and values the contributions of colleagues who have undergone transfers is essential. By establishing a systematic approach that facilitates successful adaptation and fostering a positive, accepting nursing culture, departmental transfers can be transformed into an effective strategy for enhancing the professionalism and capabilities of nursing staff.

Near infrared reflectance spectroscopy (NIRS) is widely used to assess the nutrient composition of forages. In forage, the leaf to stem ratio of alfalfa greatly affects its forage quality, with a high ratio of leaf indicated as high quality. This study aimed to evaluate the predictability of the alfalfa leaf-to-stem ratio and feed value using NIRS. Alfalfa hay was manually separated into leaves and stems by hand and the analysis samples were then made in the controlled range between 0 and 100%. Calibration models (n=320) were developed using modified partial least squares regression (MPLS) based on cross-validation. The optimal calibrations were selected based on the highest coefficients of determination in cross-validation (R2) and the lowest standard error of cross-validation (SECV). The prediction accuracy for the leaf-to-stem ratio (SECV, 5.95 vs. 5.71%; R2, 0.91 vs. 0.91) in alfalfa hay was comparable. For leaves, the standard error of calibration (SEC) was 4.94% (R2=0.94), and for stems, it was 4.81% (R2=0.94). The leaves and stems of the SEC were 4.94% (R2=0.94) and 4.81% (R2=0.94), respectively. The prediction accuracy for feed value, based on the leaf-to-stem ratio, predicted SECV values of 0.92% (R2=0.88) for crude protein (CP) content, 1.92% (R2=0.91) for neutral detergent fiber (NDF) content, 1.36% (R2=0.91) for total digestibility nutrient (TDN) content, and 9.86 (R2=0.81) for relative feed value (RFV). The results of this study demonstrate the potential of the NIRS method as a reliable tool for predicting the leaf-to-stem ratio of alfalfa hay, and show available techniques for routine feed value evaluation.

This study aimed to examine relationships of water and dietary fiber intake with various health-related factors using data from the 2016~2019 Korea National Health and Nutrition Examination Survey (KNHANES). A total of 8,419 adults aged 19~49 years were categorized into four groups: (1) sufficient intake of both water and fiber (Type 1) (n=2,235), (2) water deficiency with sufficient fiber (Type 2) (n=1,470), (3) fiber deficiency with sufficient water (Type 3) (n=1,031), and (4) deficiency in both water and fiber (Type 4) (n=3,683). General characteristics, body composition, health behaviors, dietary habits, nutrient and food intake, and dietary quality were compared. Type 4 had more female (p=0.028), older adults (p<0.001), and higher socioeconomic status (p<0.001) than Type 1. Type 1 consumed breakfast more frequently (p<0.001). Nutrition label recognition, usage of nutrition label, and all nutrient intakes were the highest in Type 1 but the lowest in Type 4. Type 1 also had better dietary variety score and nutritional quality. These findings highlight the importance of adequate water and fiber intake for balanced nutrition and suggest that targeted nutrition education is needed, especially for male and low-income groups with insufficient intake.

This study employed text mining techniques to analyze the major topics and research trends in plant ecological studies conducted in the Nakdong River basin. A total of 131 research articles published between 1977 and 2023 were collected from domestic and international academic databases. Our analysis revealed that the primary research themes include: wetland plant management and restoration, regional flora investigation, the relationship between aquatic plant communities and water quality, wetland plant community structure and distribution, riparian vegetation, and Phragmites australis (common reed). The majority of these studies were based on short-term field surveys (less than one year in duration; 79.7%), with a focus on regional flora investigation (30.5%), vegetation mapping (21.4%), and plant growth characteristics (17.6%). To ensure the longterm sustainability of the Nakdong River ecosystem, we suggest prioritizing long-term ecological research (LTER) initiatives and incorporating diverse research approaches, such as mesocosm experiments that manipulate key environmental factors. This comprehensive approach to plant ecological research will be crucial for evaluating the stability and resilience of the Nakdong River ecosystem and will ultimately contribute to the development of robust, scientifically informed decision-making processes and management strategies.

Transport concepts were identified through a review of overseas developments, with requirements derived for both accident and normal conditions. The study also presents an approach for evaluating transport stability based on land-based nuclear plant regulations, considering load conditions from drops and puncture impacts, as well as random vibrations during road transport. This work aims to support the design of mobile reactor transport systems and contribute to new regulatory and licensing procedures for advanced reactors.

농산물 재배, 수확 후 세척 등에 사용되는 농업용수는 미생물에 오염될 경우 병원균을 농산물로 전파하여 식중 독을 유발할 수 있기 때문에 관리가 필요하다. 이 연구는 2021년부터 2023년까지 하천수, 저수지, 지하수 등 다양 한 수원의 농업용수에서 대장균군과 대장균의 오염 수준 을 조사하고 자외선(ultraviolet, UV) 소독이 농업용수 내 미생물을 저감시키는 데 얼마나 효과적인지 평가하였다. 농업용수의 미생물 수질조사 결과 대장균 오염도는 수원 에 따라 차이가 있는 것으로 나타났다. 하천수의 대장균 농도는 평균 0.95±1.23 log CFU/100 mL였으며, 저수지는 평균 0.76±1.07 log CFU/100 mL, 지하수는 평균 0.1±0.47 log CFU/100 mL, 기타수원은 평균 0.6±0.87 log CFU/100 mL로 조사되었다. 수원별로 보면 하천수, 저수지, 지하수 순으로 높은 미생물 오염을 보였다. 다양한 용수 조건에 서 자외선 소독을 테스트한 결과, 99.9% 미생물 비활성화 에 필요한 UV 선량은 증류수에서 1.2-1.6 mW/cm2·sec, 농 업용수 원수에서 2.0-2.7 mW/cm2·sec 범위 였다. 고형물 응집제를 통해 전처리된 농업용수는 처리되지 않은 농업 용수 원수에 비해 자외선 투과율이 높았으며, 미생물을 99.9% 감소시키는 데 필요한 자외선 선량이 더 낮아지는 것으로 나타났다. 용수 자외선 투과도가 감소함에 따라 소독 효율이 감소함에도 불구하고 본 실험에서 조사된 선량 은 수질에 상관없이 수초 내 99.9%의 미생물 감소를 달 성하는 것으로 나타나, UV 소독기술은 농업용수의 미생 물 위험을 줄이는 데 효과적인 방법으로 판단된다.

군산과 고성(경남)의 벼(Oryza sativa)와 무안과 화순의 물억새(Miscanthus sacchariflorus)로부터 2012년 9월과 2013년 3월 사이에 Chilo속(풀 명나방과)에 속한 월동유충들을 각각 채집하였다. 시토크롬 c 산화효소 1 유전자의 부분염기서열과 성충 생식기 형태에 근거하여 벼에서 채집된 유충 은 이화명나방[C. suppressalis (Walker, 1863)]으로, 물억새의 유충은 나도이화명나방[C. niponella (Thunberg, 1788) (synonym, C. hyrax Błeszyński, 1965)]으로 동정되었다. 다른 여러 지역에서 이화명나방 성페로몬트랩에 포획된 성충 중 종 동정에 적용된 개체들은 모두 대상종인 이화명나방으 로 동정되었다. 두 종은 말령태로 월동하였다. 월동유충들을 채집한 후 수원지방의 야외조건에 두었을 때, 5~6월에 용화하였고, 14~88%의 유충 생존 율을 보였다. 3월 중 고성(경남)에서 채집된 이화명나방 유충과 1월 말에 화순에서 채집된 나도이화명나방 유충들은 채집 당시 휴면이 종료되어 발육을 진행하고 있는 것으로 추정되었다. 두 종이 분리되지 않은 채 인위적으로 만들어진 실내집단의 갓부화 유충을 수원 야외에서 사육하였을 때, 6월 하순 부터 9월 사이에 발육을 시작하는 유충들이 월동유충이 생성되는 휴면에 유도되었다. 6월 하순부터 7월 하순 사이에 사육을 시작한 집단들로부터는 비월동태와 월동태 유충들이 같이 발생하였다.

In a previous study, beverages containing Centella asiatica extracts (CAE) that exhibited anti-inflammatory effects were prepared. This study aimed to establish the optimal extraction conditions for CAE to enhance its anti-inflammatory activity in functional labeling beverages (FLB-CCS) containing Aloe vera gel powder and Codonopsis lanceolata extract, and to determine their effects on intestinal epithelial cells. Initially, FLB-CCS 1 (containing 3% CAE) and FLB-CCS 2 (containing 1% CAE), which had varying CAE extraction ratios, displayed no significant cytotoxicity in IL-1β-induced inflammatory intestinal epithelial (Caco-2) cells. FLB-CCS 1 significantly more effectively inhibited the production of inflammatory factors, such as IL-6 and monocyte chemoattractant protein-1 (MCP-1), compared to FLB-CCS 2. FLB-CCS 1 also reduced the mRNA expression of genes encoding IL-6 and MCP-1. Additionally, FLB-CCS 1 regulated the expression of IL-1 receptor type 1 by inhibiting the nuclear translocation of the NF-κB transcription factor p65. In conclusion, these results suggest that an increased CAE extraction ratio (FLB-CCS 1) could enhance the anti-inflammatory activity and serve as materials in functional labeling beverages for intestinal health.

The winter forage triticale (x Triticosecale Wittmack) cultivar ‘Onggoljin’ was developed in 2018 by Central Area Crop Breeding Division, the National Institute of Crop Science, Rural Development Administration, as a winter forage. ‘Onggoljin’ has green leaves with medium length and narrower blade width compared to ‘Joseong’. ‘Onggoljin’ has shorter length spikes, a slightly longer awn than ‘Joseong’, and it’s anther without anthocyanin color. The seeds of ‘Onggoljin’ was shorter in both length and thickness than those of ‘Joseong’, with a yellowish-brown grain coat color. The heading date of ‘Onggoljin’ was at April 23 nationwide on average, two days later than ‘Joseong’. It exhibits stronger winter hardness, and simmilar lodging and desease resistance compared to ‘Joseong’. The plant height of ‘Onggoljin’ was longer than that of ‘Joseong’, and its fresh matter yield and dry matter yield were 46.31 tons/ha and 15.75 tons/ha, respectively, representing 18% and 17% higher than ‘Joseong’. The forage quality characteristics of ‘Onggoljin’ at late milky stage were crude protein content of 6.2%, neutral detergent fiber content of 59.5%, acid detergent fiber content of 34.4%, and total digestible nutrients content of 61.8%, and the silage quality was grade 2. The grain yield of ‘Onggoljin’ was 6.57 tons per ha.

This study examined domestic consumption trends in the development of mushroom-based alternative food products. It found that 85.5% of consumers were aware of alternative foods, with a higher recognition rate among younger age groups and variations based on household composition and monthly income. Additionally, 70% of consumers familiar with alternative foods had tried them. Among those who had not, taste (16%) and purchasing challenges (15%) were the primary barriers. Minced meat was the most commonly consumed alternative (25%), while dumplings (7%) and burgers (1%) were less popular. Notably, dumplings and burgers showed the highest potential for development using mushroom-based ingredients. These findings provide valuable foundational data for advancing mushroom-based alternative food products.

Tricholoma matsutake is a commercially valuable fungus that produces gourmet mushrooms. The artificial cultivation method that is currently used to produce fruiting bodies involves the transplantation of pine trees infected with T. matsutake from their natural habitats and the successful infection of young pine trees and mushroom production have been reported in Hongcheon. In this study, T. matsutake genetic diversity and relationships in this region were investigated. A genotype analysis was conducted on 25 fruiting bodies collected from an area approximately 2.56 km2 in size using 10 simple sequence repeat (SSR) markers. The analysis revealed 25 genotypes and 23 alleles with mean observed (HO) and expected (HE) heterozygosities of 0.312 and 0.293, respectively. The average polymorphism information content (PIC), which indicates marker polymorphism, was 0.257. A phylogenetic analysis showed no clear correlation between collection location and genetic distance; a spatial autocorrelation analysis indicated no significant genetic structure within 1600 m; and the Mantel test showed no significant correlation between genetic and geographic distances. These results were consistent with previous reports on Japanese populations. This study provides insights into the genetic diversity and structure of T. matsutake at a local scale and highlights the need for further studies across broader geographical ranges.
