The mechanical properties and low-cycle fatigue behavior of the hot-rolled AA2195 Al-Li alloy taken along the longitudinaldirection and transverse direction were investigated. The anisotropy ductility of the alloy with the short-term naturalaging (T4-SN), long-term natural aging (T4-LN), and T6 artificial aging alloy is mainly related to the grain structure andgrain boundaries, whereas the weakened anisotropy of ductility is attributed to the appearance of PFZs. The T4-SN andT4-LN specimens present the cyclic hardening phenomenon due to the interaction of dislocations with dislocations or theGuinier–Preston zone. The cyclic softening phenomenon in T6 specimens is attributed to that the dislocations cut throughthe T1precipitates, and some dislocations bypass the non-shearable precipitates, which activates more potential slip systemsto shear the T1precipitates.

( Ming Guo Jiang ),( Ben Wang ),( Li Fang Yang ),( Shuang Jun Lin ),( Hai Rong Cheng ) 한국미생물 · 생명공학회 2011 Journal of microbiology and biotechnology Vol.21 No.1

As a rare sugar alcohol, L-arabitol can be used in food and can prevent extra fat deposits in the intestinal tract. Commercially, L-arabitol is prepared from pure L-arabinose by hydrogenation, which needs a high temperature and high pressure, leading to a high production cost for Larabitol. Therefore, this study describes a novel L-arabitol production method based on biological purification from the xylitol mother liquor, a cheap and readily available raw material that contains a high concentration of Larabitol. First, a novel Bacillus megaterium strain was screened that can utilize xylitol, sorbitol, and mannitol, yet not L-arabitol. The isolated strain was inoculated into a medium containing the xylitol mother liquor under formulated culture conditions, where a high L-arabitol yield (95%) and high purity (80%) were obtained when the medium was supplemented with 50 g/l of xylitol mother liquor. Upon further purification of the fermentation broth by ion exchange and decolorization, L-arabitol was crystallized with a purity of 98.5%.

Objective: We wanted to report our experience of metallic stent placement after insufficient balloon dilation in graft hemodialysis patients. Materials and Methods: Twenty-three patients (13 loop grafts in the forearm and 10 straight grafts in the upper arm) underwent metallic stent placement due to insufficient flow after urokinase thrombolysis and balloon dilation. The indications for metallic stent deployment included 1) recoil and/or kinked venous stenosis in 21 patients (venous anastomosis: 17 patients, peripheral outflow vein: four patients); and 2) major vascular rupture in two patients. Metallic stents 8 10mm in diameter and 40 80 mm in length were used. Of them, eight stents were deployed across the elbow crease. Access patency was determined by clinical follow-up and the overall rates were calculated by Kaplan-Meier survival analysis. Results: No procedure-related complications (stent fracture or central migration) were encountered except for a delayed Wallstent shortening/migration at the venous anastomosis, which resulted in early access failure. The overall primary and secondary patency rates ( standard error) of all the vascular accesses in our 23 patients at 3, 6, 12 and 24 months were 69% 9 and 88% 6, 41% 10 and 88% 6, 30% 10 and 77% 10, and 12% 8 and 61% 13, respectively. For the forearm and upper-arm grafts, the primary and secondary patency rates were 51% 16 and 86% 13 vs 45% 15 and 73% 13 at 6 months, and 25% 15 and 71% 17 vs 23% 17 and 73% 13 at 12 months (p = .346 and .224), respectively. Conclusion: Metallic stent placement is a safe and effective means for treating peripheral venous lesions in dialysis graft patients after insufficient balloon dilation. No statistically difference in the patency rates between the forearm and upper-arm patient groups was seen.

Numerical Modeling on Post-Local Buckling Behavior of Circular and Square Concrete-Filled Steel Tubular Beam Columns

Yongtao Bai,Xuchuan Lin,Ben Mou 한국강구조학회 2016 International Journal of Steel Structures Vol.16 No.2

In concrete-filled steel tubular (CFST) beam-columns under cyclic loadings, local buckling of restrained steel tube, crushing and slipping of the confined concrete could have significant influences on strength and stiffness degradation. This paper presents a numerical model based on fiber element discretization for simulating the deterioration behaviour of both rectangular and circular CFST beam columns under axial load and cyclic loading. Uniaxial stress-strain relationships for steel and concrete in CFST beam columns are proposed by introducing unified parameters to control the extent of deterioration. Axial contraction caused by local buckling was accounted by defining an inelastic region that promises plasticity and strength degradation. The numerical model was validated by comparing the simulation results and the associated experimental results. The influences of diameter-to-thickness ratio, concrete and steel strength ranging from normal strength to high strength on the deterioration behavior of circular and rectangular CFST beam-columns were analyzed. Finally, through recognizing the limit state to trigger global strength degradation of a CFST frame, the developed numerical model is applicable for simulating global behavior of CFST frames under collapse-level deformations.

DON’T BE A PASSING FAD: THE SUSTAINED COMPETITIVE ADVANTAGE OF HOTELS’ THEMING STRATEGY IN CHINESE MARKET

Lee, Wen-Yin,Wang, Kuo-Ching,Wu, Ben,Chuang, Wan-Hua,Hsiao, Chia-Lin 글로벌지식마케팅경영학회 2018 Global Marketing Conference Vol.2018 No.07

Theming has become a powerful strategy in hospitality industry to enhance customer engagement and to serve as a competitive advantage in a saturated market. Based on the resource-based theory (RBT) of sustained competitive advantage (SCA), this qualitative study is an exploratory attempt to investigate 10 hotels in Mainland China and Taiwan that have adopted the theming strategy. Introduction As hospitality industry is facing the increasingly intense competition and saturated markets, theming is continuously gaining importance of hotels strategy to survival and growth. In addition, strategy planning determines the future of firms and discover the method to achieve success (Yong & Oh, 2004). Holjevac (2003) predicted that at the beginning of the 21st century, hotels with themed strategy which characterized by a synthesis of esthetics, quality and functionality would become the future trend. Theming has created the differentiation in hospitality market, using the creation of experience-centric service. Pine & Gilmore (1999) once pointed out that the shaping of experience stems from simple and powerful thematic transmission. Moreover, experience marketing can bring preference to the product and service of the enterprise, which in turn leads to a positive value experience (Milman, 2013). The results of theming strategy will positively influence the satisfaction and return rate (Wu, M. Li, & T. Li, 2018). Theming strategy with the advantage of pursuing innovation and uniqueness was extensively used to firms in the competitive hospitality market, like hotels in Las Vegas and Macao. However, some scholars concerned about the sustainability for the strategy due to the high-capitalized cost and the customers sensitive taste (Wassler, Li, & Hung, 2015). Although hotels with themed strategy has flourished in Chinese market more than decade, market research has lagged behind to support the industry’s growth. Researchers still adopted a rather normative paradigm by either identifying the superficial issue focused on experiential market concept or pointing out problems without providing more sustainability related solutions (Zou & Peng, 2008; Xiao, Zhang, & Huang, 2013). Barney (2007) indicated that internal resources could lead to the competitive. Therefore, this study aims at understanding the factors that lead theming strategy to be sustainable in hotels, based on the resource-based theory of sustained competitive advantage. The article has the following structure. The first section establishes a theoretical foundation through a review of strategy literature on theming. The second section proposes a conceptualization of theming strategy’s sustained competitive advantage (SCA) consisting of firms intrinsic resources based on resource-based theory (RBT), also, describe the assessment of key sustainable factors of theming strategy through interview the superior manager of 10 hotels in Mainland China and Taiwan that have adopted the theming strategy. The final section discusses the study’s findings, implication, and suggests directions for future research. As this research is one of the first studies in the hospitality field that identifies the resources and capabilities of the hotels’ theming strategy from the inside viewpoint, the contribution of this study will, and can conceptualize and discover the key factors to sustain the competitive advantage of themed hotel managing strategy Literature review Theming strategy for hotels Theming is a complete and ubiquitous way of impressing consumers and improving brand awareness (Olson, 2004). From theme parks, casinos, department stores, aviation, restaurants to hotels, thematic construction has the dominant influence on most customer engagement (Mu?oz, Wood, & Solomon, 2006). Hotel theming strategy, based on the theme of cultural material (history, city story, etc.) either from surrounding area or develop within hotel, display the core value of theme from physical resources, as buildings and facilities, to invisible resources, as atmosphere and service, which would, in the end, create a valuable and unforgettable customer stay experience(Zins, 1998). Xiao, Zhang, & Huang (2013) noted that the distinctive consumer experience at the theme hotel can impress customers, and, ultimately enhances brand recognition, customer engagement and repurchase intention. On the other hand, Wassler, Li, and Hung (2015) has indicated the pros and cons for the China themed hotels, which are the uniqueness to create competitive advantages that are difficult to imitate. On the contrary, the gaining of customers’ sense of demand can lead to the difficulties to fulfill customers’ taste and the ingrained capital with the narrow development is hard to recapitalize once invested. Importance of sustainability for theming strategy. Due to the strong specific image of the themed hotels, some cases developed as a passing fad in the hospitality field. Although prior study has indicated the importance of theme selection for themed hotels (Xiao et al., 2013), seldom literature focus on the overall implementation and application within hotels’ ins and outs, also the SCA issue of hotels management. Xiao & O'Neill (2010) pointed out that the analysis of internal resource is enable manger to realize and build sources of competitive advantage, which is emanated from the resource-based view of strategy. In Resource Based Theory (RBT), scholars thought that resources and capabilities from firms could bring lasting competitive advantage to the organization, and companies that have SCA (Wernerfelt, 1984). Organization have SCAs can reach outstanding performance by constantly creating and delivering the core value through price, trust, aesthetics and functionality to its target markets (Barney, 1991). Thus, in order to observe the SCAs for themed hotels management, this research will employ on internal resource view based on RBT to explore the SCAs from the internal aspect of themed hotels. Methodology We illustrate the key factors and analyze the importance of internal resources for the SCA of hotels’ theming strategy by means of a qualitative study in which 10 hotels applied theming strategy in Mainland China and Taiwan were surveyed using semistructured interviews. For the research question, a qualitative approach offers the advantage to allow an adequate, in depth analysis of the complex relations between internal recourses and SCA of theming strategy. These 10 hotels adapted theming strategy are chosen by non-probability snowball sampling method, below Fig.1 is the hotels list for 10 interviews in Taiwan and Mainland China. In addition, because China with a vast territory is limited to cover all area, the research focuses on Zhejiang province and Shanghai city, which have well-developed economy and rich tourist resources. All interviewees of the hotels will be the superior manager who decides the core value and leads the hotel’s future. The interview will be three part to proceed. First, in warm-up period, interviewer will frame an informal and trust environment, first step is to confirm interviewees’ background. The second part will be identify period; there will be a questionnaire, which adopted Chuang (2000), whose survey to prioritize the 5 dimension of internal resources that essential to hotel theming strategy management. Finally, we will confirm the competency, competitive advantage, and the strategy to achieve the sustainability for hotels theming strategy. We present conclusions for research and practice, as well as deriving practical recommendations for hotels’ theming strategy in Chinese market based on our findings. Preliminary findings The preliminary findings of the research will base on the key themes that emerge from in-depth interview to understand perceptions of hotel managers regarding theming. The result will be presented and discussed in three period. First, based on the questionnaire result from the interviewees, we will recognize that what the priority degree about the five dimension of internal resources is regarding perception of theming in hotel strategy. Second, 10 interviews will transcribe from voice recordings to pages of text, then the text will go through the coding technique, in which the raw and efforts data will be identified as the themes and subthemes. All the analyzed process will be carried by expert triangulation. Finally, through the experts examining on the links of themes and quotations, we will create a view of framework that would explore the relationships between theming strategy and SCA, the result will find the formula for hotels adapted theming strategy to possess competitive advantage of being sustainable. Although space limitations of the conference preclude the detailed explanation of this research work, the authors believe this study will broaden the theoretical domains used in understanding internal resources and competency of hotels’ theming strategy and practical information can be observed from the findings.

Talin-1 Correlates with Reduced Invasion and Migration in Human Hepatocellular Carcinoma Cells

Fang, Kun-Peng,Zhang, Jian-Lin,Ren, Yan-Hong,Qian, Ye-Ben Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.6

Background: Talin-1 is a cytoskeleton protein that participates in cell migration and plays a role in tumor formation, migration, and metastasis in different types of cancer. Chinese investigators have observed that the levels of Talin-1 protein and mRNA expression in HCC tissues are significantly lower than in the adjacent non-cancerous tissue. However, Japanese investigators have reported that Talin-1 is upregulated in HCC. Tln2 as homologous gene of Tln-1, which encodes a very similar protein, but the role of Talin-2 is very little known in primary liver cancer (PLC). We investigated whether the expression of Talin-1 in PLC may be associated with the histological subtype as well as the role of Talin-1 in tumor cell invasion and migration using human hepatocellular carcinoma cell lines. Materials and Methods: We measured the mRNA expression levels of Talin-1 and Talin-2 in five human liver cancer cell lines and normal human liver cell ($LO_2$ cell line) by real-time PCR and the protein expression levels of Talin-1 by Western blot. Migration and invasion of the cells were assessed using transwell assays and cell scratch experiments, respectively, and proliferation was assessed by soft AGAR colony formation. Results: Talin-1 and Talin-2 expression differed significantly between the five human liver cancer cell lines and $LO_2$ cell line (p<0.05). Compared with the $LO_2$ cell line, the invasion and migration capabilities of the five cancer cell lines differed significantly (p<0.05). Similarly, the colony-forming ability differed (p<0.05). Conclusions: High levels of Talin-1 expression are correlated with reduced invasion and migration as well as decreased malignancy in human liver cancer cell lines; the suppression of Talin-1 promotes invasion and migration. In addition, Talin-2 may be correlated with invasion and migration in human hepatocellular carcinoma.
