The enhancement of photoluminescence of Au-$TiO_2$ nanoparticles by surface plasmon resonance has been studied extensively by experiment in recent years. For the purpose of optimizing the photoluminescence property of Au-$TiO_2$ nanoparticles, the manufacturing parameters related to the Au nanoparticles and $TiO_2$ nanoparticles need to be considered. In this paper, Drude model and Maier's effective volume method are used to analyze the variation of the metal nanoparticle radius, separation between metal nanoparticle and dielectric molecule, and total absorption cross-section with original radiative efficiency on the photoluminescence property of Au-$TiO_2$ nanoparticles. The results show that to obtain the optimized enhancement factor for photoluminescence process, the size of Au nanoparticle is about 13 - 20 nm, the separation between Au nanoparticle and $TiO_2$ molecule is about 5 -15 nm, the total absorption cross-section of $TiO_2$ molecules is about $1-100nm^2$ and the original radiative efficiency of $TiO_2$ molecule is weak about 0.001- 0.1. With these fabrication parameters, the photoluminescence property of Au-$TiO_2$ nanoparticles can be enhanced several thousand times compared to traditional $TiO_2$ nanoparticles.

Facebook is very popular among young people and especially university students. Therefore, Facebook is the most logical platform to be used by academic libraries for promotional purposes and reaching out to user communities. This study aims to measure the effectiveness of using Facebook in connecting with students in academic libraries. A questionnaire survey was conducted to collect research data from students at four Vietnamese universities. A total of 1,670 valid questionnaires were returned, and more than half of the respondents were females between the ages of 18 and 22 years. The survey results found that libraries' Facebook pages did not receive adequate attention and interaction from students. Besides that, the information needs of students and social media content in general affected student acceptance of libraries' Facebook pages. These factors are demonstrated by the great majority of students who used Facebook often for various purposes, but fewer accessed library pages and they were not actively engaged in library posts. Students were interested in the information they already tended to get from libraries and were optimistic about the quality of library posts. However, they still expected more diverse and attractive content from the libraries. The findings of this study can help libraries create a close connection with students by satisfying their needs and expectations on Facebook.

This study aimed to explore the factors affecting the foreign direct investment (FDI) intentions of investors into Quang Ninh province, located in the north-eastern of Viet Nam. Researchers used two main methods, namely, Exploratory Factors Analysis (EFA) and the Structural Equation Model (SEM) based on partial least squares structural equation modeling (PLS SEM) to explore and measure the impact of factors affecting the investors' FDI intentions into Quang Ninh province. The empirical analysis used data from the survey of 206 domestic and foreign investors into Quang Ninh province, including representatives of the Board of Directors, members, and management representatives at the department level, with reliable tools (SPSS 26 and SmartPLS 3.0 software). The research results identified the following factors affecting investment into Quang Ninh: FDI attraction policies have the strongest impact on the investors' FDI intentions; it is followed by infrastructure, public services and human capital with strong effects on intentions of investors' FDI; and finally the standards of living that affects the investors' FDI intentions. There is also a positive relationship between all the factors and the investors' FDI intentions. Several recommendations are further suggested to enhance attraction of foreign direct investment into Quang Ninh province.

This study examines the dispute resolution culture and negotiation strategy in Vietnam. We adopt area studies methodology in order to analyze dispute resolution and negotiation strategy in Vietnam, since the dispute resolution and negotiation strategy are keenly connected with the culture, law, institution, and economic system of the society. Our findings are as follows. First, Vietnamese society has the culture that has the characteristics of maternal society and patrilineal society. Vietnamese women has traditionally participated in the economic activity. Second, Vietnamese people showed loyalty to the nation. Third, Vietnamese society is shown to belong to the culture of collectivism. In addition, we investigate the multi-faced characteristics of Vietnamese dispute resolution culture and negotiation strategy. Our findings are as follows. First, Vietnamese people utilize middlemen in implementing dispute resolution and negotiation. Second, Vietnamese people prefer long-term negotiation style. Third, Vietnamese people is accustomed to face-saving culture. Fourth, Vietnamese people prefer the indirect communication style. Fifth, Vietnamese people prefer written document instead of oral agreement in contract. Sixth, Vietnamese people and firms prefer ADR to formal law.

The gDNA isolated from Korean cuttle fish (Sepia esculenta Hoyle) from Sockcho (SOCKCHO), Seocheon (SEOCHEON), Incheon (INCHEON) and Vietnamese cuttle fish (VIETNAM), were amplified by PCR. Here, the seven selected primers (BION-A07, BION-A09, BION-A11, BION-A20, BION-B04, BION-B06, and BION-B14) were used to generate the unique shared loci to each population and shared loci by the four cuttle fish populations. In this study, the primer BION-A11 detected 112 shared loci by the four populations, major and/or minor fragments of sizes 300 bp, 400 bp, 700 bp and 1,000 bp, respectively, which were identical in all samples. The dendrogram obtained by the seven primers indicates five genetic clusters: cluster 1 (SOCKCHO 01-SOCKCHO 07), cluster 2 (SEOCHEON 08-SEOCHEON 10), cluster 3 (SEOCHEON 11-SEOCHEON 14), cluster 4 (INCHEON 15-INCHEON 21), and cluster 5 (VIETNAM 22-VIETNAM 28). The shortest genetic distance that displayed significant molecular differences was between individuals 25 and 26 from the Vietnamese cuttle fish (0.025), while the longest genetic distance among the twenty-eight cuttle fishes that displayed significant molecular differences was between individuals SOCKCHO no. 02 and SEOCHEON no. 12 (0.640). Individual of Seocheon and Incheon cuttle populations was somewhat closely related to that of Vietnamese cuttle fish population. Even though it could not be affirmed by a single case, such a result seems to be closely connected that the Korean peninsula is subject to climate changes by global warming. In conclusion, our PCR analyses revealed a significant genetic distance among the four cuttle fish populations.

The dragon is a special imaginary figure created by the people of East Asia. Its archetypes appeared primarily as totemic symbols of different tribes and groups in the region. The formation of early dynasties probably generated the molding of the dragon symbol. Dragon symbols carried deep imprints of nature. They concealed alternative messages of how ancient people at different locations dealt with or interacted with nature. Under pressure to standardize in the medieval and late imperial periods, the popular dragon had to transform physically and ideologically. It became imposed, unified, and framed, conveying ideas of caste classification and power, and losing itsecological implications. The dragon transitioned from a semi-ecological domain into a total social caste system. However, many people considered the "standardized" dragon as the symbol of the oppressor. Because of continuous orthopraxy and calls for imperial reverence, especially under orthopractic agenda and the surveillance of local elites, the popularized dragon was imbued within local artworks or hidden under the sanctity of Buddhas or popular gods in order to survive. Through disguise, the popular dragon partially maintained its ecological narratives. When the imperial dynasties ended in East Asia (1910 in Korea, 1911 in China, 1945 in Vietnam), the dragon was dramatically decentralized. However, trends of re-standardization and re-centralization have emerged recently in China, as the country rises in the global arena. In this newly-emerging "re-orthopraxy", the dragon has been superimposed with a more externally political discourse ("soft power" in international relations) rather than the old-style standardization for internal centralization in the late imperial period. In the contemporary world, science and technology have advanced humanity's ability to improve the world; however, it seems that people have abused science and technology to control nature, consequently damaging the environment (pollution, global warming, etc.). The dragon symbol needs to be re-defined, "re-molded", re-evaluated and reinterpreted accordingly, especially under the newly-emerging lens-the New Confucian "anthropocosmic" view.

Nowadays, with the constant enhancement in the health of the economy, the average income and living standard have accordingly increased, making the need for financial independence a favorable choice. This research aims to identify the factors affecting the financial independence of young people. The authors implement quantitative analysis, with a set of primary data collected from a survey of 2664 Vietnamese people aged from 18 to 28. The research results demonstrate the considerable impact of monetary, psychological, group-related, and family-related factors on the financial independence of young people. The results of the sample analysis provide adequate evidence to reject the correlative relationship between family and group factors and the financial independence of young people. In addition, there are 3 factors, including demographic factors, monetary factors, and psychological factors, all have varying degrees and directions of influence on young people's financial independence. Most of the mentioned variables reflect a positive effect on financial independence. The only exception is the education variable, illustrated by its negative standardized beta value. A significant difference in financial independence between genders also is reported, suggesting that males seem to have a higher level of financial independence than females.

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.

As strategies for creating profits are differentiated by the national economic system and development strategies related to firms' geographical scope, they depend on the spatial contexts and product characteristics. In this perspective, strategies for the profit creation of Korean textile and clothing FDI firms invested in Vietnam has involved in the geographical differentiations in accordance with the development path of transitional economies, changes in institutional environments and the characteristics of products. Therefore. the main purpose of this research is to identify the way in which they have their own identity in transitional economies by investigating business pattern, commodity chain and extra-firm relations, which are related to institutional dynamics in Vietnam. There are two main characteristics of Korean textile and clothing FDI firms in Vietnam. The first is that all business activities involved in the commodity chain of them from R&D to production is controlled by global retailer and distributors, which is the buyer-driven commodity chain and the typical commodity chain of the textile and clothing industry. The second could be defined as over- or unforced embeddedness into the institutional legacy of the Soviet system, because they have been incorporated into pre-existing networks based on reciprocal relations in Vietnam.

Objectives The number of marriage immigrant women has been increasing in the past several years in Korea and their adaptations to the new environment have been an important social issue. The aims of this study were to evaluate the psychosocial and mental health statuses of Vietnamese marriage immigrant women (VMIW). We intended to compare the mental health of VMIW with married Vietnamese women living in Vietnam and reveal the demographic or psychosocial factors affecting their mental health. Method Subjects comprised one-hundred-forty-three VMIW who enrolled in multiculture family support centers in Chungbuk Province and forty-eight women from Vinh Phuc province in Vietnam. Marital satisfaction, domestic violence and social support were evaluated as psychosocial factors, and the Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI) and General Health Questionnaire (GHQ) were used to evaluate mental health. Results VMIW had a larger age gap with their husbands but better psychosocial statuses. BDI (p = 0.20), BAI (p = 0.08), GHQ (p = 0.13) scores of VMIW were not significantly different compared to Vietnamese residents. Marriage duration of VMIW affects significantly their marital satisfaction, social support and depressive levels (p < 0.01). The level of domestic violence showed a significant difference according to the educational levels of their husbands, composition of family members and marriage process (p < 0.05). VMIW with older husbands and jobless VMIW had low levels of anxiety (p < 0.01). Conclusion The results suggest that VMIW have no difference in mental health compared to Vietnamese women living in Vietnam which is contrary to general expectations. However, various environmental factors, such as marriage duration, have an effect on the mental health of VMIW. As marriage duration is proven to be important factor on mental health of VMIW, more extended duration of care and interventions are needed to maintain good mental health. Networking system connecting mental health screenings by the multiculture family support center to the local mental healthcare center is needed to care those with poor screening outcomes.
