        This study develops the model to estimate the links between social capital, social entrepreneurial self-efficacy, perceived desirability and social entrepreneurial intention. Besides exploring the direct impacts of social capital, social entrepreneurial self-efficacy, and perceived desirability on social entrepreneurial intention, this study also focus on discovering the mediating roles of perceived desirability and social entrepreneurial self-efficacy on this relationship. Throughout adopting measures from some previous studies, the authors design the questionnaires and distribute to students in Vietnam. The study presents some demographic information of 289 students, who are studying at university and colleges in Vietnam. Then, the validity and reliability of scales are assessed using the value of Cronbach’s alpha, Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA). In addition, by utilizing the structural modeling structure (SEM), the authors show that social capital plays the important role in shaping social entrepreneurial self-efficacy, perceived desirability, and social entrepreneurial intention. Interestingly, besides the direct effects on social entrepreneurial intention, perceived desirability and social entrepreneurial self-efficacy also mediate the correlation between social capital and social entrepreneurial intention. Also, with the interesting findings of the study, the authors propose several recommendations for policy-makers, educators and academics to promote the social entrepreneurship and innovation among Vietnamese students.

        The Sogdian Merchants were the undertakers of international trade on the Land Silk Road in the Middle Ages, and their business footprints spread all over Eurasia. The ancient trading currency of Sogdian Merchants is a key to study the trading history of the region and the entire Silk Road. Although the economic strength of Sogdiana was strong, the country was very weak and had been controlled by the powerful forces around it. Sogdian Merchants wanted to use large amounts of currency for exchanging activities in countries along the Silk Road, they must imitate the currency of the powerful countries that controlled the Silk Road or even use their currencies directly to meet the needs of long-distance transshipment trade. Most scholars agreed that the Persian Sassanian silver coins used to be the currency of circulation along the Silk Road. Whether the main purpose of the unearthed Byzantine gold coins was to act as circulating currencies on the Silk Road at that time, there is still a great controversy.

        Purpose - The purpose of this paper is to investigate the effects of online game properties, social interaction, and player satisfaction on intention to online games in Chinese gamers. Research design, data, and methodology - This study is an empirical analysis assuming that properties of online games, social interaction and satisfaction will induce Chinese gamers' intention to play online games. We set the relationship between the six variables as follows. First, the properties of online games, exogenous variables, were identified by three factors: entertainment, security, participation and challenge. Second, we had input social interaction among gamers as another exogenous variables. Third, the gamer's satisfaction of online games was added to the research model as a mediating variable between exogenous variables and endogenous variables. Finally, gamer's intention to play influenced by satisfaction and social interaction was used as final endogenous variable. The data used for the empirical analysis were collected through questionnaires for Chinese under age 35 who enjoy the online games. The data used in the research were finally extracted from 195 questionnaires. The collected data were tested through the analysis of the measurement model (Step 1) and the analysis of the structural model (Step 2). The covariance structure equation model (SEM) was used for the analysis. The measurement model and structural model were evaluated by the maximum likelihood method. Results - The results of the empirical analysis are as follows. The satisfaction of online games were entertainment and security had a significant effect to satisfaction; but participation and challenge and social interaction had no significant effect on satisfaction. The social interaction among gamers and the satisfaction with online games have a significant influence on the intention to play online games. As a result, the attributes of the game were affecting the intention to play the game after satisfaction. Social interaction influenced the intention to play online games rather than satisfaction itself. Conclusions - This study provide some practical implications for the new companies who want to enter the online game industry and seek to competitiveness in China, and provide theoretical implications on the role of interaction among gamers in the study of online games.

        Vessel Traffic Services (VTS) textbooks should adhere as closely as possible to the Standard Marine Communication Phrases (SMCP) set by the International Maritime Organization (IMO). The purpose of the present paper is to examine English linguistic features in VTS textbooks used in China and Korea in comparison with the SMCP in order to determine the degree to which these textbooks adopt and utilize the SMCP. Textbooks used by VTS operators in China and Korea and the SMCP were separately edited and compiled into corpora. In analyzing the data, both quantitative and qualitative approaches were adopted. Software WordSmith 5.0 was utilized to retrieve statistical information and concordance samples. The findings show that the lexico-grammatical patterns in the Chinese and Korean VTS textbooks generally deviate from the formulas of SMCP. The results of the study are expected to help in the design of VTS textbooks and to standardize Maritime English.

        POST-TENSIONING GROUT PROBLEMS Bonded post-tensioned structures are at increased risk of corrosion and failure of the tendons when there are defects in the installed grout. The most common grout problems (defects) include: • Voids: Voids are common at high points of tendon ducts as a result of grout bleeding and inadequate grouting. Standard cement/water grout has typically produced grout with 3 to 5% bleed. • Chloride contaminated grout: Chloride contamination may result from the use of chloride contaminated grout or mixing water or the long-term exposure of the structure to marine environments or de-icing salts. • Soft grout: Soft grout may be created if excessive water is added during grout mixing, and wick induced bleeding causes localized grout with high water-cement ratio. THE SOLUTION The Post-Tech PTI Impregnation system has been developed to mitigate corrosion caused by these problems. The system utilizes the interstitial spaces between the wires of each strand in a multi-strand tendon to deliver (transfer) a unique corrosion inhibiting, impregnation material along the length of the cable. The impregnation material seeps between the wires of the strands to impregnate the surrounding grout or concrete. The impregnation material is designed to form a corrosion-resistant film on any exposed steel surfaces such as steel strands which are exposed in grout voids, and to make the grout more corrosion and moisture resistant. Laboratory Confirmation Laboratory confirmation was completed on tendon specimens provided by one DOT and grouted “lollipop” samples. The tendon specimens provided to Vector were sections of external tendons which had been removed from an existing bridge. Lolipop samples comprised a single strand section which was centrally grouted in a cylindrical block of prepackaged PT grout. Laboratory testing confirmed the ability of the impregnation material to travel along the length of the specimen, to soak into the grout surroundingthe strands and to pass from strand to strand across the cross-section of a grouted tendon. Accelerated laboratory testing also confirmed the ability of the impregnation process to reduce corrosion by over 90%. Field Demonstration and case study The demonstration project was completed on external tendons in a box girder bridge in Jacksonville, FL (I-95 / I-295 Interchange). The demonstration project verified the capability of impregnating the full length of 256’ and 205’ grouted tendons from end anchorage locations, the capability of impregnating up to 100’ in each direction from a mid-point location, and the capability of the impregnation material to penetrate the grout adjacent to the strand. FDOT has implemented PTI Impregnation on the tendons of I-4 Connector in which soft grout was found. All selected tendons were successfully impregnated. Free water/moisture was pushed out of the tendons during the impregnating process. CONCLUSIONS Laboratory testing confirmed the ability of the impregnation material to travel along the length of the specimen, to soak into the grout surrounding a strand and to reduce corrosion by over 90% when exposed in an accelerated corrosion cell. Field demonstration at the I-95/295 Interchange in Jacksonville, Florida and Implementation on I-4 Connector in Tampa, Florida has demonstrated the following: • All strands of 256’ long grouted tendons can be impregnated full-length from an end anchorage location, • Impregnation material can flow up to 100’ in each direction from a mid-point location,. • Impregnation material can penetrate grout adjacent to a grouted strand, and • Free water/moisture can be pushed out of the tendons during the impregnation process.

        Corrosion of reinforcing steel leading to structural deterioration and failure of reinforced concrete structures is a serious problem for port and highway agencies, and facility owners. Galvanic anodes have been used to extend the service lives of concrete structures since late 1990s. Embedded Zinc sacrificial anodes have been included in patch repairs of steel reinforced concrete structural elements suffering from corrosion since the mid-nineties. The anodes installed in a UK bridge in 1999 have been monitored, and 10-year data monitored data will be discussed. Galvanic anodes have been used widely in patch repair since then. Recognizing the inadequate monitoring of impressed current cathodic protection that will make it in-effective, distributed galvanic anodes were developed in early 2000s to address the global corrosion issues in concrete structures. Many departments of Transportation (DOTs) and Ministries of Transportation tried and monitored the anodes initially for a few years and considered the trials successes, and have widely used galvanic anodes in bridge decks, abutments, pile jackets and marine structures since then. This paper introduces different levels of corrosion protection offered by galvanic anodes and the various galvanic anode systems used in concrete structures. Various applications of the galvanic systems to extended service lives of concrete structures are presented.

        Enhancing yield has been a major challenge of agriculture. In rice, tiller number is one of the important biomass and yield components. A maize mutant grassy tillers1 (gt1) increases lateral branches in maize. The GT1 gene encodes a class I homeodomain leucine zipper (HD-Zip) protein. In maize, the gt1 expression is induced by shading and is dependent on the activity of teosinte branched1 (tb1), a major domestication locus controlling tillering and lateral branching. To estimate the biological role and agricultural utility of gt1 in rice, rice homologue (OsGT1) has been isolated and its overexpressors and RNAi lines were generated. Field data showed that OsGT1 overexpressors reduced tillers and panicles while RNAi lines increased them, compared to wild type. Shade signal is an important factor in determining lateral branching. To understand the relationship between OsGT1 and shade avoidance, plants have been grown under 50% shading in the field. Also, double genetic combinations with phytochrome mutants (phyA, B, and C) are being examining for tillering phenotype. These ongoing researches will provide insights in determining the action of OsGT1 on branching and shade avoidance in rice.

        Environmental stresses including drought, extreme temperatures, and high salinity are major factors that severely limit crop productivity worldwide. To overcome yield loss due to these environmental stresses, a large number of researches have been conducted to understand how plants respond to and adapt these environmental stresses. Posttranscriptional regulation as well as transcriptional regulation of gene expression is recognized as a key regulatory process in plant stress responses, and these cellular processes are regulated by diverse RNA-binding proteins (RBPs). Over the last years, we have extensively investigated the functional roles of RBPs that harbor an RNA-recognition motif at the N-terminal half and a glycine-rich region at the C-terminal half (glycine-rich RNA-binding proteins, GRPs), zinc finger-containing GRP, and cold shock domain proteins (CSDPs) in Arabidopsis thaliana, rice (Oryza sativa), wheat (Triticum aestivum), and rapeseed (Brasicca napus) under stress conditions. Our comparative analysis demonstrated that certain family members display RNA chaperone function during stress adaptation process in monocotyledonous plants as well as in dicotyledonous plants. These findings point to the importance of the regulation of mRNA metabolism in plant response to environmental stresses and shed new light on the practical application of these RBPs to develop stress-tolerant transgenic crops.

        We investigated genetic diversity among and within the populations of cultivated ginseng (Panax ginseng C. A. Meyer ) using SRAP profiles. A total of 24 ginseng plants were sampled from the three populations (two from China, one from Korea). Since all these populations are previously shown closely related to each other assister groups, we used Panax quinquefolium L. and wild ginseng as a reference species, which is not "within the sister group". All individuals from the three populations were screened with a total of 36 primer pairs with 26 primers generated from 328 SRAP bands of DNA gels. The mean gene diversity (HE) was estimated to be 0.057 within populations (range 0.032-0.067), and 0.086 at the species level. The genetic differentiation (Gst=0.31) indicates that genetic variation apportioned 30% among populations and 70% within populations. Generally, the result of this study indicates that ginseng contains high molecular variation in its populations.
