최근 ChatGPT로 대표되는 인공지능의 급격한 발전은 인공지능 에 대한 낙관과 비관이 엇갈리는 가운데 기독교 선교가 새롭고도 실제적 인 방향을 모색해야 할 필요성을 제기했다. 이를 위해 본 연구는 행위자 -네트워크 이론을 주요 이론적 틀로 활용하여 인공지능을 단순한 도구가 아닌 인간과 상호작용하는 행위자로 인식한다. 이러한 관점에서 현재 인공지능 기술의 최전선에 있는 거대 언어 모델의 기술적 특성과 작동원리를 상세히 분석하여 인공지능이 인간과 맺는 관계에 주목한다. 이러한 이해를 토대로 인공지능과의 선교적 접점을 모색하기 위한 방안은 첫째, 인공지능을 선교 현장으로 인식하는 것, 둘째, 인간에게만 주어진 선교적 삶을 사는 것. 셋째, 인공지능을 선교사역의 협력자로 받아들이는 것, 넷째, 오픈소스 거대 언어 모델을 활용한 선교적 목적의 인공지능을 개발하는 것이다. 본 연구는 인공지능 시대의 기독교 선교 가 단순히 인공지능을 도구로 활용하는 차원을 넘어, 인공지능과의 협력적 관계를 통해 새로운 선교의 지평을 열어가야 함을 제안한다. 이는 데이비드 보쉬가 주장한 것처럼, 선교는 각 시대의 변화에 따라 새로운 패러다임으로 변화되어야 한다는 관점에 기반한다.

본 연구는 맹종죽(Phyllostachys edulis) 부산물의 고부가가치 활용을 위한 기초연구로, 맹종죽림 조사 및 소각처리를 통한 죽회 생산 기술을 개발하고자 하였다. 맹종죽림 현장에서의 죽간 벌채 후 남은 상층 부산물(잎, 잔가지, 끝대)과 수년간 방치된 하층 부산물의 바이오매스 총량을 파악한 결과, 입죽 상태의 맹종죽을 벌채할 경우, 활용될 죽간의 중량비는 56.6%, 죽림 내에 방치되는 상층 부산물의 중량비는 43.3%로 나타났다. 방치됐던 하층 부산물은 ha당 약 26톤이 잔존해 있었다. 한편, 부산물을 죽회로 활용하기 위해 소형 소각로 및 대형 무연소각로를 이용한 소각처리를 수행하였다. 현장에 설치된 소각로에서의 조사 결과, 소형소각로(화실, 57.2 ㎥)는 1시간에 10 kg, 1일 최대 80 kg을 소각하는 반면, 대형 무연소각로 (화실, 791.4 ㎥)는 1시간에 70 kg, 1일 최대 560 kg을 소각하여 약 7배의 효율을 보였다. 2차 회화 과정을 통해 얻은 순수 죽회의 수율은 약 84%였으며, 칼륨(80,000 ppm↑), 칼슘(50,000 ppm↑), 인(20,000 ppm↑), 마그네슘(20,000 ppm↑), 망간(10,000 ppm↑), 철(10,000 ppm↑) 등 다양한 무기원소가 함유되어 있었다. 본 연구는 대나무 벌채 현장에서 수행된 실험을 바탕으로, 맹종죽림의 지속 가능한 경영과 새로운 부산물 활용 방안에 대한 제시로 큰 의의가 있을 것으로 판단된다.

This study examined differences in breakfast habits, mental health, and the prevalence of allergic diseases among 9,549 adolescents from father-headed and mother-headed families, using raw data from the 2017~2019 Korea Youth Risk Behavior Web-Based Survey. Of the total participants, 44.6% came from father-headed families, while 55.4% were from mother-headed families. Single-parent adolescents showed the highest likelihood of eating breakfast every day of the week (24.5%), but they also had a significant tendency to skip breakfast entirely (24.3%). There was no significant difference in breakfast frequency between those from father-headed and mother-headed families. The perception of stress and subjective health status did not differ significantly between adolescents from the two types of families, although subjective health status did show significant differences among boys. Depressive experiences were notably higher in adolescents from mother-headed families (33.0%) compared to those from father-headed families (30.8%). Additionally, the prevalence of atopic dermatitis and allergic rhinitis was significantly greater in adolescents from mother-headed families (24.2% and 32.1%, respectively) than in those from father-headed families (21.1% and 26.5%, respectively). These results indicate the need for tailored nutrition and health guidance programs for adolescents from single-parent families to support the role of the absent parent.

In this study, we aim to classify personal mobility (PM)-related traffic crash data into four categories: PM-to-vehicle, PM-to-pedestrian, PM-single, and vehicle-to-PM crashes, and analyze the factors influencing the severity of each crash type. To overcome the limitations of existing studies in explaining the impact of independent variables on ordinal dependent variables, a random forest model was combined with the Shapley additive explanation technique. This approach visualizes the influence of independent variables on a dependent variable, providing clearer insights and enhancing interpretability. The analysis of PM traffic accidents, categorized into at-fault, single-vehicle, and victim accidents, revealed distinct key factors for each type. The main contributors to the severity of crashes caused by PM are traffic violations by teenagers and collisions with elderly pedestrians. Single-vehicle accidents were predominantly caused by overturn incidents, with inadequate driving skills among PM users aged 40 years and older, and significantly increasing severity. Victim accidents primarily occur at intersections, where the behavior of the at-fault driver and age of the PM user are critical factors influencing the severity. We identified various factors influencing the severity of PM crashes by type, highlighting the need for tailored policy measures. Proposed policies include physically separating bicycle–pedestrian shared spaces and strictly regulating illegal PM sidewalk riding, introducing PM licenses for teenagers to ensure compliance with traffic rules, and implementing regular safety education programs for all age groups. Although this study applied a new analytical technique, it relied on limited crash data, thus limiting the results to estimates.

딸기 수출에 있어서 미숙과 수확은 착색불량, 과실 품질 저 하 등 문제를 야기하지만 단순히 수확 숙도만을 높일 경우 상 품성 유지기간이 단축되는 문제가 발생한다. 따라서 본 연구 는 ‘금실’ 딸기의 수출 확대를 위해 최적의 수확 숙도를 규명 하고, 저장 중 상품성을 유지할 수 있는 수확 용기 변경 효과를 평가하고자 수행되었다. 수확 숙도는 착색도 50%, 70%, 90% 로 설정하였고, 관행적인 과실을 포개서 수확하는 다단 수확 용기와 1단 수확용기를 비교하였다. 1월, 3월, 5월에 걸쳐 수 확 착색도 및 수확용기를 달리하여 수확된 과실은 수출농가와 동일하게 예냉, 선별 및 포장, 저장 과정을 거쳤고 저장 중 1일, 3일, 6일, 12일째에 과실의 착색도, 당도, 경도, 외관지수, 무 게 손실률을 측정하였다. 연구 결과, 착색도 70% 이상에서 수 확한 딸기는 당도가 높고 판매에 적합한 착색도를 유지한 반 면 저장성은 낮아졌다. 하지만 착색도 50% 수확에서는 판매 에 적합한 착색도에 도달하지 못하였다. 다단 수확용기는 과 실 간의 밀착으로 인한 물리적 손상으로 저장 중 감모율이 높 았으며 외관 지수가 더 빠르게 감소하였다. 반면 1단 수확용기 는 외관지수 변화가 적으며 감모율이 낮아 저장 중 상품성을 유지하는 데 효과적이었다. 특히 고온기(5월)에는 90%-다단, 70%-다단보다 90%-1단 처리에서 외관지수가 더 높은 값을 보일정도로 수확용기를 변경하는 효과가 우수하였다. 결론적 으로, 수출 딸기의 고품질 유지와 소비자 만족도를 위해 수확 시 착색도를 70% 이상으로 유지하고, 기존 다단 수확용기에 서 1단 수확용기로의 전환이 필요하다.

The present study was undertaken to ascertain the temperature development characteristics of Phthorimaea operculella (Lepidoptera: Gelechiidae) across its various developmental stages. To this end, the insect was subjected to six constant temperature conditions (13, 17, 25, 27, 32, 34±1°C), relative humidity (RH) levels of 65±5%, and photoperiods of 16 : 8 h light/dark. The developmental time of larvae was longest at 13°C, and as the temperature increased up to 35°C, the developmental time tended to become shorter. At the pupal stage, all individuals developing at 13°C perished and were excluded from the calculation of the development period for the development model. To ascertain the relationship between temperature and development, a regression model was employed for analysis. The lower threshold temperature of the total immature stage was determined to be 9.4°C, and the thermal constant was found to be 454.5DD. In the analysis of the temperature-development experiment, the Lactin 2 model exhibited an optimal fit (R 2=0.90-0.98) for the total immature stage of P. operculella.

본 연구는 합성 아질산염 대체 천연보존료로 개발하고자 천연물 유래 복합추출물(NP-NAP, NP-NAMR)의 성분 특성 과 소시지에의 적용 시 품질 특성을 규명하였다. NP-NAP 와 NP-NAMR 0.5-1.0% (w/v)는 90.1-100%의 ABTS 라디 칼 저해능과 10 mg/mL에서 각각 811 μM 및 770 μM trolox 상당의 FRAP 활성을 보였다. NP-NAP와 NP-NAMR은 S. aureus와 L. monocytogenes, E. coli 및 S. Typhimurium에 대 해 0.1% (w/v)에서 99.99-100%의 감소율을 보였고 C. perfringens에 대해 1%와 2% (w/v)에서 각각 89.0-91.4%와 84.7-100% 이상의 감소율을 보였다. 천연 복합추출물 첨가 소시지 시제품의 냉장 중 품질 특성에서 4주 차 pH (6.43- 6.57)와 NP-NAMR 첨가 시 높은 a 값(23.54% 및 28.81)을 확인하였다. Springiness와 cohesiveness는 NP-NAP 1%가 높 았으나 다른 모든 시험구는 양성 대조구와 유의적 차이가 없었다(P<0.05). 냉장 중 평균 MDA (0.87-1.183 μM)는 양 성 대조구(0.93-0.96 μM)와 유사하였으며(P<0.05) 총 증가 균수(log CFU)는 1% 첨가(1.10-1.32) 시 nitrite pickling salt (NPS) 0.08% (1.31)과 유사하였고 2% 첨가 시(0.17-0.49)는 commercial product from Spain (CPS) 1% (0.53)보다 적었 다. 종합적 기호도는 NP-NAMR 2% 제외한 모든 시험구는 통계적 유의차가 없었다. 이상의 결과, 과채 추출물 유래 NP-NAP와 NP-NAMR은 항산화, 항균 활성과 안정적인 적 색도와 함께 식약처 고시 소시지류의 기준 및 규격을 만족 하여 합성 아질산염과 시판 수입품을 대체하는, 유효한 소 재가 될 수 있을 것으로 사료된다.

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.

본 연구에서는 baird paker agar (BPA)와 MC-media pad SA (MMPSA)의 황색포도상구균 검출효율과 정성 및 정 량 정확도를 비교하여 황색포도상구균 건조필름의 사용가 능성을 평가하였다. 본 실험에 사용된 재료는 마카롱(30건), 편육(30건) 및 김밥(30건), 총 90건을 실험 재료로 사용하 였다. 유통식품 90건의 황색포도상구균 검출효율 실험결과, BPA와 MMPSA의 검출효율은 48건(53.3%)으로 동일 하게 검출되었다. 또한 정량 정확도는 BPA와 MMPSA에 서 각각 2.0±0.8, 2.0±0.7 log CFU/g로 유의적인 차이가 나 타나지 않았다. 황색포도상구균의 정성 정확도 실험결과, BPA의 경우 97.7%, MMPSA의 경우 96.4%로 산출되어 유 의적인 차이가 나타나지 않았다. 황색포도상구균의 검출효 율, 정성과 정량 정확도 실험결과, BPA와 MMPSA 두 배지 에서 유의적인 차이가 나타나지 않아 황색포도상구균 정성 과 정량실험 시 MMPSA도 사용이 가능할 것으로 판단된다.

Ecological characteristics of the brown alga Ishige okamurae Yendo in its natural habitat at Janggam, Shinan on the southwestern coast of Korea were investigated from March 2023 to February 2024. The population of I. okamurae formed extensive patches along the shoreline. Environmental factors such as seawater temperature, pH, salinity, and dissolved oxygen were monitored during this study. Growth and maturation of the I. okamurae population were assessed using both qualitative and quantitative methods. This alga showed a peak growth in October when the seawater temperature was 19.9°C. It had a mean length of 7.6±1.4 cm, a mean density of 4,466.6±288.9 ind. m-2, and a mean biomass of 663.9±85.3 fresh-wt. m-2. The effective cumulative temperature required for the alga’s maturation was estimated based on growth data with a biological zero temperature of 9.2°C. Sporangia were observed from June to November when seawater temperatures ranged from 20.5°C to 14.0°C. Unilocular sporangia first appeared in June, followed by simultaneous appearance of unilocular sporangia and plurilocular sporangia from July to September. From October to November, only unilocular sporangia were observed. Thallus development began at temperatures above 9.2°C. Maturation required approximately 577 degree-days for unilocular sporangia and 801 degree-days for plurilocular sporangia.

This study was conducted in September 2023 to establish proper eating habits and enhance the nutritional knowledge of elementary school students in Daegu during a nutrition camp hosted by the Daegu Metropolitan Office of Education. A total of thirty boys and twenty-three girls participated, with an average age of 11.2 years. The breakfast skipping rate was 11.3%, while 84.9% reported eating out once or twice a week, and 86.8% indicated they consumed delivery food once or twice a week. Regarding snacks, 47.5% of students reported eating snacks twice a day, and 73.6% identified as picky eaters. Furthermore, 66% of the participating students had no prior experience with nutrition education or consulting nutritionists. The students' nutritional knowledge score before the start of the nutrition camp was 14.4 out of 20, and after the end of the nutrition camp, it statistically increased significantly to 16.4 points (p<0.001). The level of nutritional knowledge of students who participated in the nutrition camp improved significantly compared to before the start of the nutrition camp, and this result shows that various activity programs including nutrition education and nutrition counseling can be effective.

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.

본 연구는 아메리카동애등에(Hermetia illucens)의 대량 사육을 위하여 남은음식물 사료의 최적 수분 함량과 적정 사육 밀도를 조사하였다. 실 험에서는 500 g의 습식 사료의 수분 함량을 각각 30%, 50%, 70%, 90%로 조정한 후, 3,500마리의 3령 유충을 7일 동안 사육하였다. 그 결과, 90% 수분 함량에서 평균 유충 무게는 7.19 g으로 측정되었고, 70% 수분 함량에서 가장 높은 무게인 10.54 g이 나타났다. 반면, 50%와 30% 수분 함량에 서는 유충 생육이 저조한 결과가 나타났다. 적절 사육 밀도를 조사를 위해 100,000, 150,000, 200,000, 250,000 마리의 3령 유충을 70% 수분함량 의 100 kg 습식 사료에 7일 동안 처리하였다. 그 결과, 250,000 마리에서 총 유충 생산량이 22.79 kg으로 가장 높게 나타났으나, 150,000, 200,000, 250,000 마리 밀도 간에는 유의미한 차이가 없었다. 100마리당 평균 무게는 100,000 마리에서 16.90 g, 150,000 마리에서 15.20 g, 200,000 마리 에서 11.30 g, 250,000 마리에서 9.50 g으로 확인되었으며, 100,000 마리와 150,000 마리 밀도 간에는 유의미한 차이가 없었다. 결론적으로, 남은 음식물 사료인 습식사료 100 kg를 급여할 경우 수분 함량을 70%로 유지하고 사육 밀도를 15만 마리로 설정하는 것이 가장 효과적임을 확인하였다.

This study assessed dried vegetables derived from sweet potato petioles to promote the use of typically discarded aerial parts. The length (18.25 to 35.00 cm) and thickness (4.59 to 6.66 mm) of the petioles varied by variety, with ‘Hophungmi’ and ‘Tongchaeru’ showing promise for dried vegetable processing due to their longer and thicker petioles. In terms of color, ‘Hophungmi’ and ‘Shinmi’ exhibited high lightness, ‘Tongchaeru’ and ‘Hayangmi’ displayed strong redness, and ‘Pungwonmi’ had high yellowness. Rehydration rates and hardness increased over the harvest period, with ‘Pungwonmi’ and ‘Tongchaeru’ demonstrating excellent rehydration capacity. Additionally, ‘Hayangmi,’ ‘Shinmi,’ ‘Tongchaeru,’ and ‘Hophungmi’ maintained lower hardness levels, appealing to consumers who prefer a softer texture. Notably, the substantial polyphenol content (10.70 to 16.20 mg GAE/g) and flavonoid content (4.79 to 8.11 mg CE/g), along with antioxidant activity (DPPH: 1.11 to 2.14 mg, ABTS: 5.51 to 7.78 mg TE/g), indicate their potential as antioxidant-rich functional foods. This research supports the development of dried vegetable products tailored to consumer preferences.

This study optimized the gelling agent and rice protein ratio for developing elderly friendly jelly using a response surface methodology. Response surface analysis was conducted with a gelling agent (0.1, 0.2, and 0.3%) and rice protein (3, 6, and 9%) set as independent variables. Increasing the gelling agent and rice protein ratio raised the pH while lowering the total acidity. The sugar content decreased nonlinearly with a higher gelling agent ratio. The lightness (L) and yellowness (b) differed according to the addition ratios of each ingredient, and the hardness peaked at 0.3% gelling agent and 6% rice protein, but excessive rice protein addition led to a decrease in hardness. Response surface analysis indicated an optimal formulation of 0.16% gelling agent and 6.41% rice protein, with all response variables aligning within the predicted ranges, validating the model.

This study evaluated the feasibility of integrating the carbon storage of grasslands in Gangwon province into the InVEST carbon storage and sequestration model using large-scale digital land cover maps. Land cover maps from 1980, 1990, 2000, and 2010, obtained from the Environmental Geographic Information Service, were analyzed, with 28 maps examined for each year. Grassland carbon storage in Gangwon province was estimated through the InVEST software. The findings indicated that the grassland area showed an increase in 1990, followed by a declining trend, contrasting with the continuous reduction observed in actual managed grassland areas. Discrepancies between mapped and managed grassland areas were attributed to the classification criteria of the land cover maps, which included non-forage land uses such as golf courses, ski resorts, and green spaces, resulting in overestimations of grassland areas. To enhance accuracy, the adoption of land cover maps with refined grassland classification criteria is necessary. Accurate representation of grassland areas in land cover maps is critical for reliable estimation of grassland carbon storage using the InVEST software.

Oyster mushrooms were analyzed to confirm the effect of installing a convection fan on the uniformity of the environment inside the cultivation house, the quantity of fruiting bodies, and marketability for stable production. When using a convection fan, it was confirmed that the temperature, relative humidity, and CO2 concentration were maintained more uniformly than when not used.As for the characteristics of the fruiting bodies, the quantity per bottle was 177.3 g when using a convection fan, which was 17% higher than when not used, and the individual weight was 49% higher. In addition, the cap diameter, cap thickness, and stem thickness increased slightly in the convection fan treatment, and the stem length was shorter.

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.

Alfalfa hay varieties have been developed and cultivated in Korea to enhance the self-sufficiency rate of domestic roughage. The objective of this study was to compare the effects of feeding domestic and imported alfalfa on the growth performance and economic feasibility of Hanwoo bulls. This study was conducted using eight Hanwoo bulls, aged 6 to 7 months, during their growing period. Hanwoo bulls were divided into two groups: one group fed imported alfalfa and the other group fed domestic alfalfa. Dry matter intake, weight gain, and blood metabolites were analyzed for two months of the growing stage. There was no significant difference between the two groups in dry matter intake and body weight. However, the price of domestic alfalfa is lower than that of imported alfalfa, so feeding domestic alfalfa is expected to have a positive effect on reducing production costs. Further study is needed to compare not only the growth performance but also carcass characteristics after slaughter by feeding domestic alfalfa to Hanwoo for a longer period during their growing stage.

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.
