为研究大空心率的圆中空夹层钢管超高性能混凝土短柱的轴压力学性能，进行了6根大空心率的圆中空夹层钢管超高性能混凝土短柱和1根实心圆钢管超高性能混凝土短柱对比试件的轴压试验研究，分析了试件的破坏形态、荷载-应变关系曲线和横向变形系数。结果表明：大空心率的圆中空夹层钢管超高性能混凝土柱的轴压破坏形态表现为剪切型破坏和端部鼓曲破坏，其中内钢管在外钢管鼓曲的位置发生了向内的屈曲；随着空心率的增大，试件的承载力随之降低，试件的横向变形发展速度加快。采用有限元软件ABAQUS建立了轴压试件的分析模型，其中分别采用了两种混凝土本构关系模型进行了模拟，结果表明：采用两种混凝土本构关系模型模拟的破坏形态、极限承载力和荷载-应变关系曲线的弹性阶段都与试验结果基本吻合，它们的差异主要体现在极限承载力和荷载-应变关系曲线的下降段。

目的在接受体外受精/胞浆内单精子注射-胚胎移植（IVF/ICSI-ET）治疗并取得妊娠的周期中，特别是在10~20个获卵数的“magic”范围内，确定迟发性中重度卵巢过度刺激综合征（OHSS）的危险因素。方法采用回顾性队列研究方法，对2017年12月至2018年12月在广州医科大学附属第三医院接受IVF或ICSI-ET的1 386例妊娠周期资料进行分析。对发生迟发性中重度OHSS的患者数据与其他妊娠周期数据进行对比，采用单因素方差分析和卡方检验计算两组的差异。用logistic回归分析确定迟发性中重度OHSS的危险因素。结果获卵数和妊娠囊数目是迟发性中重度OHSS的危险因素，总Gn剂量为其保护因素（PPP=0.003）为危险因素。两者的OR值分别为0.948和2.209，95%CI分别为（0.922， 0.975）和（1.278， 3.222）。AUC分别为0.624和0.595，95%CI分别为（0.565， 0.684）和（0.529， 0.661）。总Gn剂量（PP

由于结构的连续性,使得局部火灾下的网架结构中圆钢管杆件表现出典型的轴向约束杆件力学特征,这种轴向约束的存在使杆件高温屈曲后仍具有一定的承载力。基于轴向约束杆件高温屈曲后力学特征量相关方程,采用MATLAB数学求解器,开展大规模参数分析,得出关键参数影响下,轴向约束圆钢管高温屈曲后极限承载力随着长细比的增加而先降低后趋于不变,随着荷载比的增加而先略有增加后增幅趋缓,随着约束刚度比的增加而先增加后不变。基于2 300个算例结果,拟合得到约束圆钢管高温极限承载力计算公式。拟合计算公式与相关方程得到的解析解吻合较好,可作为网架结构圆钢管杆件抗火承载力验算依据,也为进一步研究网架结构受火失效机理奠定了基础。

SDN（软件定义网络）有效地简化了网络的配置与管理,使网络的革新更加快捷。利用控制器作为ARP（地址解析协议）代理,能显著地减小数据层面的广播流量,缓解因广播带来的带宽资源浪费。然而,控制器多采用被动的方式下发流表,在处理大量的广播包时会产生极大的扩展性问题。文章提出了一种基于SDN的分布式ARP代理方法,将多个局域网的网关作为ARP代理,各局域网内部的ARP请求报文以单播的方式转发到其网关做统一处理。实验结果表明,该方法不仅大大减少了网络中的广播流量和ARP请求响应延时,而且极大地缓解了SDN控制器的负载,提高了SDN的扩展性。

漂流，因而生命有無限可能；遷移，因而生命有如河流般長遠。本文敘事探究描述的是一位臺商子女維妮在中國大陸的教育與文化經驗。從13歲小學畢業後，進入中國大陸的教育體制，維妮在當地求學10年，從中學到大學，求學、就職經歷共有13年之久。維妮，具有不同於臺灣成長的教育經歷，臺商子女面臨哪些成長經歷、認同和自由的選擇，遷移世代具有如何與眾不同的文化特質？我們教育可以關心的是什麼？可以做些什麼？遷移如何造就新的一代？他們又如何思索自己與文化、地方的觀念？女性主義常常批判主流意識的許多看法，多元詮釋和看法與主流不同，並產生新的故事。敘事探究中，研究者與維妮一起探索建構和協商合作她的故事。在後殖民文學中，Naipaul也曾分析自己這樣的文化碰撞，認為認同鬆散的人，反而使自己處於「建構／拆解」、「接納／拒絕」、「同化／異化」的曖昧狀態，卻也使他創作出靈魂的文本，超越國界的人類關懷。瞭解遷移世代具有自我敘說的文本，說出他們的故事，也道出教育中少數族群的位置所在。 The study focuses on “Moving Generation”. The girl lived in the Mainland China about 13 years. The Children of Taiwanese Businessmen name is “Winnie” This research’s methodology included the literature review, narrative inquiry. Through Winnie’s story, we can understand her life and identity. What do they learn there and whether children can adapt to their life? Winnie has deep experience and local culture in Mainland China. Understand “Moving Generation” have their story and social context. And we can face up to a great diversity of the generation.

近年來批判教育學逐漸成為臺灣教育社會學領域中的重要論述，對於反省臺灣教育的深層結構和實踐提出許多的質疑和呼籲。本文主要探討兩個面向：一是了解批判教育學的學說特徵，將之視為一種對抗權力、朝向主體解放的文化論述和民主實踐；二是探討當代批判教育學所遭受的批評和學說分歧，了解批判教育學的不同修正版本，並將上述現象視為文本政治的過程。結語部分包含對批判教育學在臺灣的觀察和省思。 Critical Pedagogy has become an increasing important academic discourse in the field of sociology of education recently which provided many questions and warnings for reflecting the structure and practice of education in Taiwan. Briefly, there are two main domains in this articles: one is to clarify the characters of critical pedagogy by treating it as the discourses and practice toward struggle of power, liberation and praxis of democracy, the other is to investigate the criticism and division of critical pedagogy, explore different versions of critical pedagogy and put it as a process of textual politics. The conclusion including the discussions about the influences and implications of critical pedagogy in Taiwan and some reflections.

Objective: To discern the association between autism-like behaviors and resilience within the adolescent demographic. Methods: A total of 7 063 middle school students were selected to assess ASD-like behaviors and resilience in adolescents using the Autism Spectrum Screening Questionnaire (ASSQ) as well as the Resilience Scale for Chinese Adolescent (RSCA). Subgroups bounded by P5 and P95 of the total ASSQ score, a comparative analysis of the resilience scores between these groups was executed. A correlation evaluation and linear regression analysis was carried out between ASSQ and RSCA scores from all participants. Results: The RSCA scores within the high ASSQ scoring group, were inferior to those in the low scoring group. ASSQ scores were negatively correlated with RSCA scores for the full sample (Ps <0.01); Social interaction scores on the ASSQ were negatively correlated with the five-factor RSCA scores (β = 0.23, 0.27, 0.11, 0.23, 0.37, Ps <0.05). Conclusion: There was a negative association between autism spectrum disorder-like behaviors and resilience in adolescents, with more severe social interaction symptoms being associated with poorer resilience.

In order to alleviate the problems of randomly initializing users and items, ignoring the importance of different convolutional layers, and having too few negative samples with low quality in recommendation systems, this paper proposed AMONS. Specifically, the algorithm used adjacency matrix for embedding optimization of users and items, and introduced layer attenuation coefficients in convolutional layer aggregation to distinguish the importance of different layers. Next, it generated a filtered set of negative samples for each pair of user positive samples, allowing the model to fully utilize the historical interaction data between users and items, and better learn user preferences. The experiments were conducted extensively on the Gowalla and Amazon-Books public datasets. Compared to related methods, AMONS achieves the best performance, demonstrating the effectiveness of the method. [ABSTRACT FROM AUTHOR]

A retrospective enrollment was conducted on 181 patients with liver cirrhosis who underwent endoscopic treatment with EGVB at the First Affiliated Hospital of University of Science and Technology of China from February 2017 to May 2019, followed up for a minimum duration of 5 years. The demographic characteristics including gender, age, etiology of liver cirrhosis (viral, alcoholic, autoimmune, others), presence of ascites, hepatic encepha⁃ lopathy severity (none, stage 1 ~ 2, stage 3), portal vein thrombosis status, occurrence of liver cancer or portal hypertensive gastric disease along with other complications were recorded. Additionally, peripheral blood indexes [aspartate aminotransferase (AST), alanine aminotransferase (ALT), white blood cell count (WBC), total bilirubin (TBIL), albumin (ALB), platelet count (PLT)], prothrombin time parameters [prothrombin time (PT) and prothrombin time international normalized ratio (PTINR)], portal vein diameter and splenic vein diameter measurements as well as Child grade assessment were collected alongside sequential treatment details and rebleeding time. According to the occurrence of rebleeding within 5 years after endoscopic treatment, the 181 cases were divided into two groups: the non⁃rebleeding group (n = 124) and the rebleeding group (n = 57). Univariate and multivariate analyses were conducted to identify risk factors associated with rebleeding within 5 years after endoscopic treatment. Additionally, Kaplan⁃Meier analysis was performed to assess the cumulative bleeding rate at 1, 3, and 5 years. Results The results of both univariate analysis and binary logistic regression analysis revealed that elevated TBIL levels and increased portal vein diameter were significant risk factors for rebleeding within 5 years following endoscopic treatment in patients with EGVB (P < 0.05). The Kaplan⁃Meier curve demonstrated that out of the 181 patients, there were 41 cases of cumulative bleeding within 1 year, 54 cases within 3 years, and 57 cases within 5 years, resulting in cumulative bleeding rates of 22.65%, 29.83%, and 31.49% respectively. Conclusions The long-term rebleeding rate remains elevated following endoscopic treatment of EGVB in cirrhotic patients, with TBIL levels and portal vein diameter identified as independent risk factors for long ⁃ term rebleeding after endoscopic treatment of EGVB in liver cirrhosis. Therefore, patients with higher TBIL levels and/or cirrhosis should be given priority for endoscopic treatment of EGVB. [ABSTRACT FROM AUTHOR]

Objective To investigate the characteristics of oral clinical manifestation and risk factors of patients infected with novel corona virus (COVID-19). Methods A total of 649 COVID-19 patients admitted to Beijing Friendship Hospital Affiliated to Capital Medical University from December 2022 to June 2023 were enrolled. All patients were divided into the young (18-40 years), middle-aged (41-65 years) and elderly groups (> 65 years) according to age. The changes in oral clinical manifestation and related risk factors during COVID-19 infection were investigated and analyzed. Results Among 649 infected patients, 231 were male and 418 were female, with an average age of (42.69±12.55) years. Except loose teeth, the differences were statistically significant in the incidence of other oral clinical manifestation during the positive and negative periods (all P < 0.05). After age grouping, there were significant differences in the incidence of taste disorder (young group vs. elderly group, middle-aged group vs. elderly group), pulpitis/apical periodontitis (young group vs. middle-aged group), gingival swelling and pain (middle-aged group vs. elderly group), gingival itching and swelling (middle-aged group vs. elderly group), dry mouth (middle-aged group vs. elderly group, young group vs. elderly group), and oral ulcers (middle-aged group vs. elderly group, young group vs. elderly group) during the positive period (all P< 0.017). During the period of negative conversion, there were significant differences in the incidence of gingival swelling and pain (young group vs. middle-aged group, young group vs. elderly group), dry mouth (middle-aged group vs. elderly group, young group vs. elderly group), and oral ulcers (middle-aged group vs. elderly group) (all P < 0.017). After gender grouping, in the positive period, the incidence of taste disorder and dry mouth in the female patients was significantly higher than that of male counterparts (both P < 0.05), whereas the incidence of tongue discomfort in male patients was significantly higher compared with that of female patients (P < 0.05). During the negative conversion period, there was a significant difference in the incidence of taste disorder between two genders (P < 0.05), and the incidence of other oral manifestation did not significantly differ between two genders (all P > 0.05). Univariate and multivariate Logistic regression analyses showed that both female gender and hypertension were the risk factors for the changes of oral clinical manifestation in COVID-19 patients (both P < 0.05). The drugs taken by patients during COVID-19 infection were not associated with the changes of oral clinical manifestation (all P > 0.05). Conclusions Oral clinical manifestation probably differ during different stages of COVID-19 infection, which might be associated with gender and age, etc. Extensive attention should be paid to oral hygiene of COVID-19 patients. For patients with high risk factors (female gender and hypertension), oral hygiene education should be strengthened and specific preventive measures and guidance should be delivered, aiming to maintain and improve their oral hygiene conditions.
