The effects of aqueous extract of Schizandrae Fructus (AESC) on lead (Pb)-induced changes of monoamine neurotransmitters in the hippocampus (HIP) of adult rats were investigated. Male Sprague-Dawley rats were received intraperitoneal (i.p.) administration of Pb acetate (5 mg/kg/d) for 28 days and sacrificed 7 days after the last administration. Concentrations of norepinephrine (NE), dopamine (DA), serotonin (5-HT), 5-hydroxyindole acetic acid (5-HIAA) in HIP were measured by HPLC. There were significant decreases of NE, DA, 5-HT and 5-HIAA in Pb treated rats (P < 0.05), while pretreatment with AESC (100 mg/kg/d or 300 mg/kg/d, p.o., 2 h before Pb) greatly inhibited the decrease of monoamine transmitters, respectively (P < 0.05). Also, AESC (300 mg/kg/d) significantly increased the reduction of glutathione contents and superoxide dismutase activities in HIP induced by chronic Pb. These results suggest that AESC ameliorates Pb-induced depletion of monoamine neurotransmitters in HIP through its antioxidant activity.

The hindgut of horses is an anaerobic fermentative chamber for a complex and dynamic microbial population, which plays a critical role in health and energy requirements. Research on the gut microbiota of Mongolian horses has not been reported until now as far as we know. Mongolian horse is a major local breed in China. We performed high-throughput sequencing of the 16S rRNA genes V4 hypervariable regions from gut fecal material to characterize the gut microbiota of Mongolian horses and compare them to the microbiota in Thoroughbred horses. Fourteen Mongolian and 19 Thoroughbred horses were used in the study. A total of 593,678 sequence reads were obtained from 33 samples analyzed, which were found to belong to 16 phyla and 75 genera. The bacterial community compositions were similar for the two breeds. Firmicutes (56% in Mongolian horses and 53% in Thoroughbred horses) and Bacteroidetes (33% and 32% respectively) were the most abundant and predominant phyla followed by Spirochaete, Verrucomicrobia, Proteobacteria, and Fibrobacteres. Of these 16 phyla, five (Synergistetes, Planctomycetes, Proteobacteria, TM7, and Chloroflexi) were significantly different (p<0.05) between the two breeds. At the genus level, Treponema was the most abundant genus (43% in Mongolian horses vs 29% in Thoroughbred horses), followed by Ruminococcus, Roseburia, Pseudobutyrivibrio, and Anaeroplasma, which were detected in higher distribution proportion in Mongolian horses than in Thoroughbred horses. In contrast, Oscillibacter, Fibrobacter, Methanocorpusculum, and Succinivibrio levels were lower in Mongolian horses. Among 75 genera, 30 genera were significantly different (p<0.05) between the two breeds. We found that the environment was one of very important factors that influenced horse gut microbiota. These findings provide novel information about the gut microbiota of Mongolian horses and a foundation for future investigations of gut bacterial factors that may influence the development and progression of gastrointestinal disease in horses.

본 연구에서는 중국 실업계 고등학생들을 대상으로 이들이 지각한 사회적 지지와 학 교 참여 간의 관계에서 학업동기 및 전공 만족도가 매개하는 지에 대해 탐색하였다. 이 를 위해 중국의 대도시인 호남성(湖南省) 웨양시(岳阳市)에 소재한 실업계 고등학교 재학생 총 554명(남학생: 313명, 여학생: 241명)을 최종 분석대상으로 하였다. 본 연구 결과, 중국 실업계 고등학생들이 지각한 사회적 지지, 학업동기의 ‘내재적 동기’와 ‘외재 적 동기’, 전공 만족도 및 학교 참여 간의 유의한 정적 상관이 있는 것으로 나타났다. 반 면, 학업동기의 ‘무동기’ 요인은 다른 요인들과 유의한 부적 상관이 있는 것으로 나타났 다. 성별차이 분석결과, 남학생이 여학생에 비해 사회적 지지의 ‘부모 지지’와 ‘교사 지 지’를 더욱 많이 받은 것으로 나타난데 반해, 여학생이 남학생에 비해 사회적 지지의 ‘또래 지지’를 더욱 많이 받은 것으로 나타났다. 또한, 여학생이 남학생에 비해 높은 수 준의 학교 참여를 보였는데, 특히 ‘행동적 참여’와 ‘정서적 참여’ 수준이 더 높은 것으로 나타났다. 마지막으로, 사회적 지지와 학교 참여 간의 관계에서 학업동기와 전공 만족 도가 매개하는 것으로 나타났다. 중국 실업계 고등학생들을 대상으로 이들의 사회적 지지, 학업동기, 전공 만족도 및 학교 참여 간의 구조적 관계를 탐색한 본 연구는 중국 의 실업계 고등학생들의 학교 참여 향상 방안을 모색하는 데에 도움을 줄 수 있을 것으 로 기대된다. This study explored whether academic motivation(i.e., intrinsic motivation, extrinsic motivation, and amotivation) and major satisfaction mediate the relationship between social support(i.e., parents, teachers, and peers) and school engagement by Chinese vocational high school students. Data were collected from 554 students (i.e., 313 male students and 241 female students) from vocational high schools located in Yueyang, Hunan Province in China. It was observed that there were significant positive correlations among social support, intrinsic and extrinsic motivation, major satisfaction, and school engagement. On the other hand, amotivation showed negative correlations with other variables. Male students showed higher teacher support and parental support than female students, while female students showed higher peer support than male students. In addition, female students showed higher school engagement than male students, especially higher behavioral and emotional engagement. It was also found that academic motivation and major satisfaction were mediated in the relationship between social support and school engagement. The results of this study is expected to be used as basic data for seeking ways to improve school engagement of Chinese vocational high school students.

Synergistic and sustainable activation of peroxymonosulfate by nanoscale MWCNTs-CuFe2O4 as a magnetic heterogeneous catalyst for the efficient removal of levofloxacin

Zhao Jing,Xiao Pengfei 한국화학공학회 2023 Korean Journal of Chemical Engineering Vol.40 No.6

Nanoscale CuFe2O4 was anchored on the surface of multiwalled carbon nanotubes (MWCNTs) as a magnetic heterogeneous catalyst to achieve efficient and sustainable activation of peroxymonosulfate and degradation of levofloxacin through the synergistic effect of the above materials. The catalyst properties were characterized by a series of detection techniques. It was found that the mass ratio of MWCNTs-CuFe2O4, operational parameters and common interfering substances influenced the levofloxacin removal efficiency to a certain extent. This study sheds light on the ultraefficient removal of levofloxacin with the MWCNTs-CuFe2O4(1:3)/peroxymonosulfate system, which has advantages over other reaction systems. More importantly, we propose two pathways of peroxymonosulfate activation, including free radicals and nonfree radicals, in which superoxide radicals and signal oxygen are the main active species. In addition, we observed that the MWCNT surface groups contributed to the peroxymonosulfate activation processes with the generation of extra reactive species. The Fe3+/Fe2+ and Cu2+/Cu+ redox cycles are conducive to the continuous generation of active species. The results of the catalyst recycling test, metal ion leaching test and mineralization test suggested that the fabricated catalyst had excellent catalytic stability, sustainability and mineralization ability. In addition, twenty-one intermediates were detected using liquid chromatography-mass spectrometry, and three possible degradation pathways were further proposed. MWCNTs-CuFe2O4 makes up for the shortcomings of transition metals and single carbon materials in activating peroxymonosulfate to treat wastewater and have significant potential to improve the separation and catalytic capacity of the catalyst. This study provides new ideas for the design of high-performance multiphase catalysts for applications in catalytic oxidation and proposes new insights into the mechanistic investigation.

Objectives: To assess knowledge of HPV and attitudes towards HPV vaccination among the general female population, government officials, and healthcare providers in China to assist the development of an effective national HPV vaccination program. Methods: A cross-sectional epidemiologic survey was conducted across 21 urban and rural sites in China using a short questionnaire. 763 government officials, 760 healthcare providers, and 11,681 women aged 15-59 years were included in the final analysis. Data were analyzed using standard descriptive statistics and logistic regression. Results: Knowledge of HPV among the general female population was low; only 24% had heard of HPV. Less than 20% of healthcare providers recognized sexually na$\ddot{i}$ve women as the most appropriate population for HPV vaccination. There was high acceptance of the HPV vaccine for all categories of respondents. Only 6% of women were willing to pay more than US $300 for the vaccine. Conclusions: Aggressive education is necessary to increase knowledge of HPV and its vaccine. Further proof of vaccine safety and efficacy and government subsidies combined with increased awareness could facilitate development and implementation of HPV vaccination in China.

ZHAO JING,안도희 한국국제문화교류학회 2023 문화교류와 다문화교육 Vol.12 No.2

This study explored the mediating roles of time management and depression in the relationship between grit and academic adjustment perceived by Chinese international students studying in South Korea. A total of 546 Chinese international students (143 males and 403 females) enrolled in universities in Seoul, South Korea, were included in the final analysis. The results showed that there were significant positive correlations between grit, time management, and academic adjustment, while there was a significant negative correlation between grit and depression. Additionally, graduate students showed higher levels of grit and academic adjustment, particularly in motivation and performance, compared to undergraduate students. Finally, both time management and depression fully mediated the relationship between grit and academic adjustment. These findings are expected to provide educational implications for enhancing the academic adjustment of Chinese international students studying in South Korea 본 연구에서는 재한 중국인 유학생들을 대상으로 이들이 지각한 그릿과 학업적응 간의 관계에서 시간관리 및 우울이 매개하는 지에 대해 탐색하였다. 이를 위해 한국 서울에 소재한 대학교 재학 중국인 유학생 총 546명(남학생: 143명, 여학생: 403명)을 최종분석대상으로 하였다. 본 연구 결과, 첫째, 재한 중국인 유학생들이 지각한 그릿, 시간관리 및 학업적응은 서로 유의한 정적 상관이 있는 것으로 나타난데 반해, 우울과는 유의한 부적 상관이 있는 것으로 나타났다. 둘째, 유학형태(학부생과 대학원생)에 따른차이 분석결과, 대학원생이 학부생에 비해 높은 수준의 그릿을 보였다. 또한, 대학원생이 학부생에 비해 높은 수준의 학업적응을 보였는데, 특히 ‘동기’와 ‘수행’ 수준이 더 높은 것으로 나타났다. 마지막으로, 그릿과 학업적응 간의 관계에서 시간관리와 우울이각각 완전 매개하는 것으로 나타났다. 본 연구 결과가 재한 중국인 유학생들의 학업적응 증진 방안을 모색하는 데 교육 분야에서의 시사점을 제공해 줄 수 있을 것으로 기대된다.
