An Examination of Listening Comprehension Instruction in Japanese Language Education

With the increase in Japanese language learners and resident foreigners, the training of Japanese language instructors has become a pressing issue. Additionally, the development of listening comprehension skills in Japanese language learners is highly emphasized. However, the challenges in teaching listening comprehension resulting from a scarcity of research in this area have been a source of concern for many educators in the field. This paper focuses on Japanese listening comprehension instruction and compiles the accumulated findings from recent research.departmental bulletin pape

一例补体抑制剂治疗欠佳的再生障碍性贫血-阵发性睡眠性血红蛋白尿患者的多学科诊疗分析

一例青年男性患者诊断再生障碍性贫血伴阵发性睡眠性血红蛋白尿(paroxysmal nocturnal hemoglobinuria，PNH)，经免疫抑制剂治疗后仅部分缓解。近1年贫血加重、输血依赖，考虑PNH活动性溶血所致，更换依库珠单抗治疗后贫血仍持续加重。详细询问病史发现患者慢性牙周感染，近1个月牙周疼痛溢脓伴发热。多学科讨论考虑慢性牙源性感染激活补体系统是PNH溶血加重的主要原因，急性感染影响了依库珠单抗的疗效。经多学科会诊制定治疗方案，给予静脉抗生素联合牙周冲洗、拔牙控制牙源性感染，同时继续按期输注依库珠单抗，患者临床症状好转，血红蛋白迅速上升，脱离血制品输注。该病例为通过多学科协作诊疗解决罕见病在新药物治疗中遇到的困难提供了经验参考

基于频谱碎片权值评估的弹性光网络RSA算法

EON（弹性光网络）中动态业务初次分配后会产生频谱碎片,影响后续业务的分配和网络的资源使用率。频谱碎片是EON RSA（路由和频谱分配）算法中需要考虑的核心问题之一。文章提出了一种改进的基于频谱碎片权值评估的EON RSA算法,引入新的评估参数DF（碎片离散度）,并在选路时进行考虑。理论分析和仿真结果表明,与传统RSA算法相比较,改进算法可以降低频谱碎片离散度,提高频谱资源利用率
