Hangovers, resulting from excessive alcohol intake, manifest hours after drinking, causing symptoms like thirst, headache, and fatigue. Alcohol is metabolized in the liver by alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH), with acetaldehyde and reactive oxygen species contributing to toxic effects. Morning Care (MC) products were evaluated in male and female mice to assess their impact on alcohol metabolism and hangover alleviation. The study revealed that pre-administration of MC products led to a significant reduction in blood ethanol and acetaldehyde concentrations postalcohol ingestion. This remarkable finding suggests a potential breakthrough in hangover relief. Enhanced ADH and ALDH activities were observed in blood and liver samples, indicating improved alcohol metabolism. Interestingly, gene expression levels of ADH and ALDH in the liver did not show significant differences, suggesting that MC products likely enhance enzyme activities through post-translational modifications rather than altering gene expression. These findings underscore the potential of MC products to mitigate hangover symptoms by enhancing alcohol metabolism.

이 연구에서는 선택실험법을 통해 수집한 진술선호자료를 기반으로 세 가지 모형을 이용하여 축산물(쇠고기, 돼지고기 제품)의 이력추적성과 원산지 속성에 대한 소비자 선호도를 분석하였다. 우리의 연구 결과에 따르면 쇠고기의 경우 한우 제품에 대한 지불의사금액 대비 이력추적성 속성에 대한 지불의사금액의 비율이 92~97%로 매우 높았다. 돼지고기의 경우에는 한돈 제품에 대한 지불의사금액 대비 추적가능한 속성에 대한 지불의사금액의 비율은 약 76~82% 수준이었다. 이러한 결과는 국내 소비자들이 국내산 육류 제품에 대한 선호도에 따라 어느 정도 식품 안전 속성(추적성)에 높은 가치를 두고 있음을 의미한다. 다시 말해 축산물 이력제가 쇠고기와 돼지고기의 식품안전성에 대한 소비자의 신뢰를 구축하는 데 크게 기여하고 있음을 보여준다고 할 수 있다.

Accurate and rapid detection of antibiotics is critical for protecting human health and the environment. To this end, we report a novel electrochemical sensor for the simultaneous detection of Levofloxacin (LFX) and Tryptophan (TRP) in dairy samples. Outstanding electrocatalytic activity for the oxidation of LFX and TRP is exhibited by the Activated Nanodiamond (AND) and Ti3AlC2 max phase ( Ti3AlC2max) nanocomposite-modified glassy carbon electrode ( Ti3AlC2max AND/GCE) featured in our sensor. High selectivity and sensitivity are achieved by the sensor, with limits of detection (LOD) of 20.47 nM and 0.309 μM for LFX and TRP, respectively. Moreover, strong anti-parasite capacity is demonstrated by the developed sensor, making it an excellent candidate for the establishment of a reliable sensing platform for antibiotic detection. Findings suggest that this novel sensor could serve as a valuable tool for monitoring the content of LFX and TRP in dairy samples and enhancing the safety of these products.

This study analyzed differences in the purchase satisfaction and repurchase intention of customers who buy clothing products from online platforms. The participants were teenage individuals to those in their 50s residing in Busan, Ulsan, and Gyeongsangnam-do. The data were examined via factor analysis, a t-test, Analysis of variance(ANOVA), Duncan’s multiple range test, two-way ANOVA, and linear regression analysis. The factors for satisfaction with clothing products from online platforms were wearing comfort and quality, design, and price and purchase convenience. The findings revealed that purchase satisfaction based on these factors significantly varied among the participants depending on marital status, age, and occupation. Satisfaction with wearing comfort, quality, and design differed by gender. Satisfaction with wearing comfort, quality, and price and purchase convenience varied by type of purchase and type of online platforms. The interaction effects among the variables that affected purchase satisfaction were as follows. The interaction effects among the variables for wearing comfort and quality showed significant interactions between gender and type of purchase and between occupation and type of online platforms. Those for design showed significant interactions between marital status and age, between age and occupation, and so on. The interaction effects for price and purchase convenience showed significant interactions between marital status and gender and between age and occupation. The results on repurchase intention showed significant differences in such intention by marital status, age, and occupation. Repurchase intention was influenced by wearing comfort and quality, price and purchase convenience, design, and age.

본 연구에서는 서울 북부지역에서 유통된 1,737건의 농 산물을 대상으로 잔류농약 실태 조사 및 위해성 평가를 하였다. 분석 시료는 QuEChERS 법으로 전처리한 후 GCMS/ MS 및 LC-MS/MS를 이용하여 분석하였으며, 다빈도 부적합 성분을 대상으로 직선성과 정량한계, 회수율, 상대 표준편차(RSD%) 구한 결과 OECD 및 Codex의 기준에 적 합하였다. 또한 모니터링 결과 72품목 560건(32.2%)에서 잔류농약이 검출되었으며 22품목 38건(2.2%)이 잔류농약 허 용치를 초과하였다. 잔류농약이 많이 검출된 품목은 과일류 53.8%, 채소류 33.0%, 허브류 28.6%, 두류 15.4%, 곡류가 10.5% 순이였으며, 잔류농약 허용치를 초과한 품목은 채소 류 중 엽채류, 엽경채류, 근채류, 향신료 및 버섯 등이었다. 검출된 농약은 105종으로 그 중, dinotefuran, fluxametamide, chlorfenapyr, azoxystrobin, carbendazim이 가장 많이 검출되 었으며, terbufos, carbendazim, fluxametamide 등 23종의 성 분에서 잔류 허용기준이 초과되었다. 잔류허용기준을 초 과한 농약에 대해 위해 평가를 수행한 결과 위해 지수가 0.00003-1.31406%로 매우 낮은 수준으로 산출되어 안전한 것으로 평가되었다.

펩타이드형 독소인 마이크로시스틴(microcystins, MCs) 과 노둘라린(nodularin, NOD)은 남조류라고도 알려진 시 아노박테리아에 의해 생성되는 2차 대사산물로, 독소에 오 염된 물, 토양 및 비료를 사용함으로써 농산물 내에 축적 되고 이를 사람이 섭취함으로써 건강상 위해가 발생할 수 있다. 최근 MCs과 NOD의 농산물 내 오염에 대한 관심 이 대두되며 국내외에서 여러 분석법을 기반으로 농산물 내 오염 수준을 조사하고 있다. 하지만 아직까지 수행된 연구가 많지 않으며, 특히 펩타이드형 독소 중 MCs의 분 석 연구에 치중되어 있거나 오염 취약 지역에서 재배한 농산물이 주로 오염도 조사에 사용되는 등 연구에 한계가 있으므로 MCs과 NOD의 관리를 위해서는 보다 많은 체 계적인 연구가 필요할 것으로 생각된다. 본 연구에서는 체 계적인 모니터링 및 안전관리의 기반을 마련하기 위해 MCs 및 NOD의 이화학적 특성, 독성, 분석법, 오염사례 및 관리현황에 대해 기술하였다.

In this study, the effect of Distribution efficiency through the fishery production base distribution center (FPC) on the production site board facility was studied. FPC is a new distribution system for Korean fishery products that has been promoted in earnest since 2012, and in this study, the effect before and after the introduction of FPC was analyzed using the DID (Difference in Difference) model for the effect of FPC in the fishery industry. The results of analysis shows that in the case of Wando Geumil FPC, the volume and unit price of consignment sales decreased during the analysis period, which was statistically significant. In the case of Sokcho FPC, the volume of consignment sales decreased during the analysis period, which was statistically insignificant. But the unit price of consignment sales rose during the analysis period, which was statistically significant. In the case of Gyeongju FPC, the volume of consignment sales increased during the analysis period, which was statistically significant at the 90% confidence level. But the unit price of consignment sales fell during the analysis period, which was statistically significant.

Numerous Dermestidae insects are considered significant pests because of their capacity to inflict substantial economic harm on stored food items. Trogoderma and Attagenus genera members are commonly discovered in imported grain and other food products. Usually, infestations of these species consist of various species that reproduce quickly and spread effortlessly. The small size of Attagenus and Trogoderma stored-product stages makes it extremely challenging to identify them based on their morphological characteristics. Hence, it is imperative to have precise identification techniques in place to ensure the safety and dependability of the grain industry, as well as to streamline efficient plant quarantine measures. Various molecular methods have been employed for insect species identification, such as restriction fragment length polymorphism (RFLP), amplified fragment length polymorphism (AFLP), random amplified polymorphic DNA (RAPD), single-strand conformation polymorphism (SSCP), DNA sequence analysis, and species-specific primer PCR (SS-PCR) techniques. Despite the considerable focus on quickly identifying these species in stored products in recent years, there is a notable absence of systematic molecular identification. This research highlights the use of genetic techniques to differentiate between Trogoderma and Attagenus species.
