        Evolution of the Textile Production Chain in East Asia from the Hub-Spoke Structure Viewpoint

        Tzu-Han Yang,Deng-Shing Huang,Yo-Yi Huang 세종대학교 경제통합연구소 2020 Journal of Economic Integration Vol.35 No.4

        This research utilizes hub-spoke analysis to trace the evolution of the textile production chain in East Asia during the period of world textile trade liberalization. We identify two different types of hubs via the functions they perform and track their shifting paths. The results illustrate that the Association of Southeast Asian Nations (ASEAN)-6 is a growing base for final products, while China has successfully shifted from downstream to mid- and upstream production. Although Japan’s hubness is decreasing in both the up- and midstream sectors, it reversed these disadvantages after 2004 and has reinforced its hub status in both areas. It appears that a tri-cycle momentum system is evolving, with each power wheel having its own leading position in the vertically integrated structure. At the same time, the cooperation between China and Japan through up- and midstream product trading has weakened, while that between ASEAN and Japan has grown.

        The Association between Default-mode Network Functional Connectivity and Childhood Trauma on the Symptom Load in Male Adults with Methamphetamine Use Disorder

        Shyh-Yuh Wei,Tsung-Han Tsai,Tsung-Yu Tsai,Po See Chen,Huai-Hsuan Tseng,Yen Kuang Yang,Tianye Zhai,Yihong Yang,Tzu-Yun Wang 대한정신약물학회 2024 CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE Vol.22 No.1

        Objective: The relationship between adverse childhood experiences and methamphetamine use disorder (MUD) has been shown in previous studies; nevertheless, the underlying neural mechanisms remain elusive. Childhood trauma is associated with aberrant functional connectivity (FC) within the default-mode network (DMN). Furthermore, within the DMN, FC may contribute to impaired self-awareness in addiction, while cross-network FC is critical for relapse. We aimed to investigate whether childhood trauma was associated with DMN-related resting-state FC among healthy controls and patients with MUD and to examine whether DMN-related FC affected the effect of childhood trauma on the symptom load of MUD diagnosis. Methods: Twenty-seven male patients with MUD and 27 male healthy controls were enrolled and completed the Childhood Trauma Questionnaire. DMN-related resting-state FC was examined using functional magnetic resonance imaging. Results: There were 47.1% healthy controls and 66.7% MUD patients in this study with adverse childhood experiences. Negative correlations between adverse childhood experiences and within-DMN FC were observed in both healthy controls and MUD patients, while within-DMN FC was significantly altered in MUD patients. The detrimental effects of adverse childhood experiences on MUD patients may be attenuated through DMN-executive control networks (ECN) FC. Conclusion: Adverse childhood experiences were negatively associated with within-DMN FC in MUD patients and healthy controls. However, DMN-ECN FC may attenuate the effects of childhood trauma on symptoms load of MUD.

        Korea-ASEAN Free Trade Agreement

        Paul T-W Lee,Tsung-Chen Lee,Tzu-Han Yang 인하대학교 정석물류통상연구원 2013 JOURNAL OF INTERNATIONAL LOGISTICS AND TRADE Vol.11 No.1

        This paper aims to explore the impacts of the recent development of Korean free trade agreements (FTAs) on its seaborne trade volumes. The paper firstly estimates the changes in cargo value flows caused by Korea-EU FTA, Korea-USA FTA and Korea-ASEAN FTA using a global computable general equilibrium model named Global Trade Analysis Project (GTAP) and its most recent database - version 7 with 2004 as the base year. Then a set of systematic conversion factors transferring trade value flows to volume flows of different types of commodities is calibrated according to the United Nations COMTRADE database and is used to convert the GTAP trade value flows into volume flows. Having indentified maritime cargo flows by different commodity types, this paper attempts to draw implications for maritime logistics policy in order to facilitate the trade of Korean merchandises and to propose key competitive strategy for the maritime container transport networking and logistics service providers in the Korean logistics industry.
