AIM To determine the relationship between F-18 fluorodeoxyglucose(FDG) uptake of bone marrow(BM) on positron emission tomography/computed tomography(PET/CT) and clinical factors and to assess the prognostic value of FDG uptake of BM in gastric *** We retrospectively enrolled 309 gastric cancer patients who underwent staging FDG PET/CT and curative surgical resection. FDG uptake of primary tumor was visually classified as positive or negative FDG uptake. Mean FDG uptake of BM(BM SUV) and BM-to-liver uptake ratio(BLR) were measured. The relationships of BM SUV or BLR with clinical factors were evaluated. The prognostic values of BM SUV, BLR, and other clinical factors for predicting recurrence-free survival(RFS) and overall survival(OS) were *** Of 309 patients, 38 patients(12.3%) experienced cancer recurrence and 18 patients(5.8%) died. Patients with advanced gastric cancer, positive FDG uptake, and recurrence had higher values of BM SUV and BLR than those with early gastric cancer, negative FDG uptake, and no recurrence(P < 0.05). BM SUV and BLR were significantly correlated with hemoglobin level, neutrophil-to-lymphocyte ratio, and platelet-tolymphocyte ratio(P < 0.05). On multivariate analysis, multiple tumors, T stage, lymph node metastasis, tumor involvement of resection margin, and BLR were significantly associated with RFS(P < 0.05). T stage, lymph node metastasis, hemoglobin level, and BLR were significantly associated with OS(P < 0.05). CONCLUSION BLR on PET/CT was an independent prognostic factor for RFS and OS in gastric cancer patients with curative surgical resection.

This study evaluated the state of anxiety, depression, post-traumatic stress disorder, general mental health, and mental well-beingamong citizens after a crowd-crush disaster in Korea. Individuals who experienced the crowd crush had significantly higheranxiety, depression, and post-traumatic stress disorder (PTSD) scores than those who did not (p < 0.001). Additionally,people who avoided the disaster area had significantly higher depression and PTSD scores than those who did not avoid thearea (p < 0.001). Those who directly witnessed the Seoul Halloween crowd crush had a significant difference in PTSD levels ineither group than those who experienced it indirectly (p = 0.005). There was a significant difference in PTSD scores in cases ofdirect damage or death of an acquaintance (p < 0.001). The Seoul Halloween crowd crush caused psychological damagethrough indiscriminate exposure to the public, and symptoms of PTSD appeared over a long period. It is crucial to provideessential resources for ongoing treatment and case management.

Tourism-Oriented Cultural Product Design: A Case Study of Yami Culture in Lanyu

引用

Open Journal of Applied Sciences 2024年第9期14卷 2506-2514页

作者： Hung-Cheng Tsai Yuhsiu Liu chung-Ming Tsai Department of Industrial Design National Kaohsiung University of Science and Technology Kaohsiung City

Due to the prevalence of modern commerce and mainstream culture, many indigenous cultures around the world are rapidly diminishing. These cultures, with their unique primitiveness distinct from modern culture, often attract tourists. This study integrates the indigenous Yami culture of Lanyu Island, Taiwan Region, into innovative designs from the perspective of tourists’ understanding of the local culture. In this way, tourists can experience the harmonious coexistence of the Yami tribe and nature, while these culturally rich products foster deeper experiential and emotional resonance. This study employs the Mandala thinking method for concept expansion and the Osborn checklist method for the analysis and transformation of design elements. Subsequently, designers were invited to conduct on-site travel experiences, leading to the creation of a series of Yami cultural products. Through the evaluation and validation of cultural product assessment indicators, functional commercialized products were ultimately produced. This study aims to establish a design process for cultural products through this design case. It seeks to help users recall their Lanyu Island travel experiences and appreciate the often-overlooked cultural beauty, thereby raising awareness of cultural preservation.

任务型教学法是20世纪80年代以来在对外汉语教学中逐渐形成和应用的一种新的教学方法。此后这种教学方法逐渐发展并在对外汉语教学领域得到广泛应用。由于该教学方法具有许多优点,最突出的优点是促进学生学习的创造力和主动性,提高学生的语言能力。因此,近年来世界上有很多语言学家对该教学方法从不同角度进行研究。对越南的汉语教学界来说,任务型教学法因为诸多客观条件的限制,并未在汉语教育领域中得到广泛应用,尤其是线上教学形式。本论文在前人语言专家成果的理论基础上,继续对基于任务型教学法应用在越南初级汉语口语线上课堂进行深入研究。本论文分为6章:其中第一章、第二章主要论述基于任务型教学法的理论基础,设计原则以及相关文献综述。第三章的内容是从第二章的理论基础进行教学设计,本论文的研究对象是信锦越南厂责任有限公司的越南人员,使用的教材是速通汉语教程。第四章根据第三章的教学设计进行两轮实施教学,收集学生的反馈。第五章根据教师和学生对初级汉语口语线上课堂设计任务的反馈,进行对任务型初级汉语口语教学的反思。最后,第六章针对任务型教学法在越南汉语初级口语线上课堂的设计任务和编写任务型教学法的口语教材提出建议。本研究的研究方法是行动研究,通过两轮行动研究,实施教学,提出问题,从自己实施教学中的观察和经验提出建议。本研究的教学设计结果包括:速通汉语教程第一册第八课《你的生日是几月几号?》,第十课《你家有几口人?》;第二册第一课《你在听什么?》,第二课《你平时几点起床?》基于任务型教学法设计的教案。通过这篇论文,基于任务型教学法在越南初级汉语口语线上课堂教案设计和两轮实施教学创建一个在信锦越南厂责任有限公司应用的汉语教学模式,任务的设计会考虑到学习者的学习特点。希望未来能够推广在越南河南工业区所有的中国台湾公司应用。
