        An Investigation of Mild Steel with Nitrogen-containing Inhibitor in Hydrochloric Acid

        Horng, Y.T.,Tsai, Yi-Liang,Tu, Ching-Fang,Lee, Chien-Ming,Wei, F.I.,Shih, H.C. 한국부식방식학회 2003 Corrosion Science and Technology Vol.2 No.5

        Pickling inhibitors can be used to form an adsorbed layer on the metal surface to hinder the discharge of H^+ and dissolution of metal ions. Nitrogen-containing inhibitors were selected as corrosion inhibitors for mild steel (MS) in pickling acid process. In this study, the addition of inhibitor, the pickling temperatures and the pickling times were the parameters to investigate the effects on the inhibition eficiency (IE) for MS by using weight loss measurement. Preliminary results show that the IE increased with the increase in pickling time from 10 minutes to 60 minutes, and the IE also increased with the increase in temperature at room temperature and 40℃. At the higher temperature, the IE values are higher and almost independent with the pickling time. Furthermore, the potentiodynamic polarization, open circuit corrosion potential-time and corrosion current-time studies show that nitorgen-containing inhibitor behaves predominantly as cathodic polarization. The roughness test and SEM investigation are also studied in this papcr.

      • CUSTOMER REACTIONS TO BRAND NAME REDEPLOYMENT AFTER M&A – THE MODERATING EFFECT OF M&A TYPE

        Horng-Der Leu,Hsiao-Fang Hsu 글로벌지식마케팅경영학회 2014 Global Marketing Conference Vol.2014 No.7

        In the context of M&A, how to redeploy two corporate assets is one of important organizational tasks. Among tasks, the management of intangible assets – in particular of corporate brand name is a critical element reflects consumers’ response. There has been increasing interest in the role of corporate names in academic fields. However, little attention has been paid to the different name and symbol options on M&A types. No empirical research has yet addressed branding strategies between in-market and cross-market M&A from the individual customers’ perspectives of acquired company. This paper seeks to address the research gap, by exploring acquired company customer on brand identity options in the context of post merger. Specifically, it considers the degree to which name and symbol influence acquired consumer responses. Thus, 5(brand strategy: target-dominant brand name A, acquirer-dominant brand name B, acquirer-dominant synergistic brand name BA, target-dominant synergistic brand name AB or create new brand name C) × 2(M & A types: in market or cross-market) between subject experiment design was conducted. 494 undergraduate or graduate students are the subjects from a college. Questionnaires were collected by convenience sampling. The results show that: (1). Brand name redeployment strategy has significant effect on customers’ sovereignty deprivation and brand switching intention. (2). In in-market M&A type situation, target-dominant brand tend to outperform acquirer-dominant brand strategy in decreasing the degree of acquired company customers’ perceived sovereignty deprivation and brand switching intention when compared with cross-market M&A type. (3). In in-market M&A type situation, new brand tend to outperform acquirer-dominant brand strategy in decreasing the degree of acquired company customers’ perceived sovereignty deprivation and brand switching intention when compared with cross-market M&A type. (4). In in-market M&A type situation, acquirer-dominant synergistic brand strategy tend to outperform new brand strategy in decreasing the degree of acquired company customers’ perceived sovereignty deprivation when compared with cross-market M&A type. In summary, in in-market M&A type situation, acquirer-dominant synergistic brand is the best strategy and new brand name is the second best option in decreasing the degree of acquired company customers’ perceived sovereignty deprivation when compared with cross-market type situation. The results should guide managers regarding post-M&A branding strategies.

        LuGre Model-Based Neural Network Friction Compensator in a Linear Motor Stage

        Horng, Rong-Hwang,Lin, Li-Ren,Lee, An-Chen Korean Society for Precision Engineering 2006 International Journal of Precision Engineering and Vol.7 No.2

        This paper proposes a LuGre Model-Based Neural Network (MBNN) friction compensation algorithm for a linear motor stage. For matching the friction phenomena in both the motion-start region and the motion-reverse region, the LuGre dynamic model is employed into the proposed compensation algorithm. After training of the model-based neural network is completed, the estimated friction for compensation is obtained. From the obtained result we find that the new structure gains advantage over the non-friction compensation system on the performance of the compensator in both regions. The proposed compensator is evaluated and compared experimentally with an uncompensated system on a microcomputer controlled linear motor tracking system in the final section of the paper. The experimental results show the improvement on the maximum velocity error and the root mean square tracking error in the motion-start region ranges from 34% to 53% and from 53% to 75% respectively, and in the motion-reverse region from 48% to 65% and from 79% to 90% respectively.

        The Feasibility of Using Simulated Targets in the Stomachs of Live Pigs for Full Endoscopic Submucosal Dissection Training

        ( Horng Yuan Wang ),( Shou Chuan Shih ),( Chien Yuan Hung ),( Chia Yuan Liu ),( Tze Yu Shieh ),( Ming Jen Chen ) 대한소화기학회 2014 Gut and Liver Vol.8 No.6

        Background/Aims: In endoscopic submucosal dissection (ESD) training, only a flat target lesion can usually be simulated in the normal mucosa. This study aimed to evaluate the feasibility of simulated targets in the stomachs of live pigs for complete training. Methods: Six trained endoscopists with hands-on experience with ex vivo, isolated pig stomachs were enrolled in this pilot study. An endoscopic banding device was used to create a polyp that was snared, leaving an ulcerated lesion. This simulated target model was used to perform ESD in pigs. The en bloc resection rate, procedure time, complications, quality of resection, and participants` opinions on the simulated targets were compared with the conventional model. Results: En bloc resections were achieved in all six simulated targets and six conventional models. The mean size of the resected specimens was 32.2 mm (range, 20 to 39 mm) in the simulated target group and 23.5 mm (range, 11 to 40 mm) in the conventional group. The target model had a high quality of resection and had a high satisfaction rate for margin identification and correct peripheral marking. Conclusions: Good identification of the lesion and ease of periphery marking in the target model may improve resection quality. (Gut Liver 2014;8:619-624)

        Magnetic Nano-Particles and Their Applications in Immunoassays

        Horng Herng-Er,C. C. Wu,Hong Chin-Yih,Liao S.H.,Liu C.M.,Yang S.Y.,Yang H.C. 한국물리학회 2006 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.48 No.5I

        Biocompatible magnetic nano-particles show great potential in bio-magnetic applications, such as MRI contrast agents, drug delivery, magnetically labeled immunoassays, and so on. In this work, the feasibility of magnetically labeled immunoassay using bio-compatible magnetic nano-particles is investigated. To do this, we study the synthesis technologies for magnetic nano-particles of Fe3O4, as well as the coating of various bio-probes onto the magnetic nano-particles to detect the bio-targets avidin, such as, etc. Furthermore, different measurements, like magnetic relaxation and saturated magnetization, for the amounts of bio-targets are developed. In order to achieve an ultra-high sensitivity in magnetically labeled immunoassays, we used SQUIDs because SQUIDs are the most sensitive sensors for magnetic signals. The characterizations of these magnetically labeled immunological measurements are discussed.

        The Myth of Polarization Among Taiwanese Voters: The Missing Middle

        Austin Horng-En Wang 동아시아연구원 2019 Journal of East Asian Studies Vol.19 No.3

        Are Taiwanese voters polarized? By presenting four novel visualizations based on a factor analysis of Taiwan National Security Surveys from 2002 to 2017, this article describes the contours of structural change in Taiwan politics. Overall, the cross-strait position among Taiwanese voters can be described by a stable inverted U shape over time. This arises from the fact that most nonpartisans—typically neglected in the literature on polarization—are moderate. Before 2008, increasing polarization among partisans can be attributed to pan-green voters moving toward independence. Between 2008 and 2014, decreasing polarization stems from moderates self-identifying as panblue supporters. Since 2014, a record-breaking number of nonpartisans have left the pan-blue camp, and more extreme pan-blue voters have contributed to a return of polarization among partisans. The results yield important implications for the study of polarization and populism, as well as for the future of Taiwanese politics.
