How Does Corporate Social Responsibility Affect Innovative Work Behaviour?
Viet Quoc Cao(Viet Quoc Cao ) People&Global Business Association 2023 Global Business and Finance Review Vol.28 No.4
Purpose: This research examines the effect of perceived corporate social responsibility on the employee-company relationship (organisational trust, organisational identification) and employees' future well-being and participation in innovative work practices. Design/methodology/approach: This study used a quantitative research approach by PLS-SEM analysis with a sample size of 400. The respondents are employees working for four distinct textile garment manufacturing enterprises in Vietnam. Findings: Our study found that corporate social responsibility directly impacts organisational trust, identification, well-being, and innovative work practices, and innovative work behaviours are directly related to organisational trust, employee well-being, and identification. Research limitations/implications: The study focuses on workers who have a basic understanding of corporate social responsibility. Consequently, the scope of research in diverse industries throughout the country's regions and cities must be expanded. Given the constraints, future studies should be broadened and conducted in greater detail. Each profession should concentrate its efforts on a broader range of survey subjects, such as office workers, employees, and consumers. Originality/value: Employee well-being is linked to innovative work behaviour, and the stronger the company's identity, the more likely people will be to be creative at work. The author found that people who work for a company that has a good sense of itself are more likely to be creative at work. The study shows that when employees are happy, they are more likely to work in new and innovative ways.

Internationalization of multinational companies in the globalized context is a popular topic in the academic world and it is also a strong concern of CEO/managers. However, this topic has not been well discussed in the academic community in Vietnam that can be contextualized in the typical transition economy. This paper is designed to explore critical success factors (CSF) of internationalization of large Vietnamese companies that have contributed major revenue from the international market. Through interviews with CEO/managers of successful companies geared toward world markets, the CSFs of internationalization have been identified and categorized into groups in which each CSF has interaction with each other, and together have combined impacts on the success of internationalization. The research results provide a conceptual framework to analyze factors affecting internationalization of large Vietnamese companies. Thank to this conceptual framework, further exploratory and/or confirmatory research can be developed to locate more success factors of internationalization. In addition, some particularly critical factors of internationalization success of Vietnamese companies are found to be useful to both CEO/ managers and policymakers. CEO/managers can benefit from the research results by concentrate their limited efforts/resources in managing these CSFs, and policymaker may design CSF-based policies to boost the internationalization of domestic companies.

The study aims to contribute to the improvement of project management in Vietnam. It focuses on developing new critical success factors (CSFs) which can be used to assess the success of project management in the country. This is a promising issue considering the rapid changes occurring within the business environment. The reason is because CSFs carry great consequences on project management issues, particularly in the context of Vietnam, which is currently experiencing many big scale projects involving both local and foreign investors. Two applications are utilised. One is to adapt the business model of Belassi and Tukel (1996) to observe the transitional and emerging economy of Vietnam. The other is to examine the data collected from a survey to examine the new CSFs which can then be used to assess the success of its projects and project management in Vietnam. The research results showed some remarkable differences between CSFs of Vietnam and foreign countries in both number of success factors and its impact levels which should be paid attention by foreign project managers/owners when doing investment and project management in Vietnam. The outcome generated can be useful to project owners/managers as well as policy makers in Vietnam’s business environment.
Nano delivery systems and cancer immunotherapy
Quoc‑Viet Le,최진주,오유경 한국약제학회 2018 Journal of Pharmaceutical Investigation Vol.48 No.5
Cancer immunotherapy takes advantage of immune system to fight against cancer. Current clinical immunotherapies are based on the administration of immune checkpoint inhibitors or immune modulators to reverse the immune suppression. Although robust and long-term tumor suppression is induced in “certain treated population”, single immunotherapy still suffers from limited efficacy in clinic. Combination with nanomedicine would be one of major strategies that can widen the effective patient populations and reduce side effects. The basis in combining nanomedicine and immunotherapy stems from the close relationship of tumor and immune system. Depending on the therapeutic cargo, nanocarriers can not only facilitate stronger innate or adaptive immunity but also reverse of immunosuppression. In the other hand, nanotechnology can potentiate the efficacy of immunotherapy by enhancing the delivery, retention and narrow the toxicity of immunomodulators. The strategies and rationales of nanocarrier design in the context of cancer immunotherapy are discussed in this review.

<P>This study examined the phase competition and critical thickness of ε-Fe<SUB>2</SUB>O<SUB>3</SUB> in epitaxial ε-Fe<SUB>2</SUB>O<SUB>3</SUB> thin films grown on a (100)-oriented yttrium-stabilized zirconia (YSZ) substrate using a pulsed laser deposition technique. The maximum critical thickness was found to be ∼20 nm for a single phase of ε-Fe<SUB>2</SUB>O<SUB>3</SUB> at the optimal laser spot size without impurities. Above this critical thickness, (00l)-oriented α-Fe<SUB>2</SUB>O<SUB>3</SUB> begins to appear along with ε-Fe<SUB>2</SUB>O<SUB>3</SUB>, eventually dominating in the thicker samples. These results suggest that the stability of ε-Fe<SUB>2</SUB>O<SUB>3</SUB> films are influenced by the appearance of a specific domain pattern, which becomes a favorable nucleation site for α-Fe<SUB>2</SUB>O<SUB>3</SUB>. The ε-Fe<SUB>2</SUB>O<SUB>3</SUB> films grown on the YSZ (100) substrate have a larger saturation moment than ε-Fe<SUB>2</SUB>O<SUB>3</SUB> grown on SrTiO<SUB>3</SUB> (111), and its coercive field approaches 1/4 of the maximum coercive field of ε-Fe<SUB>2</SUB>O<SUB>3</SUB> nanoparticles.</P><P>Plane view of ε-Fe<SUB>2</SUB>O<SUB>3</SUB> and α-Fe<SUB>2</SUB>O<SUB>3</SUB> unit cells on a YSZ (001) substrate oriented along the <I>c</I>-direction.

For precisely regulating the speed of a permanent magnet synchronous motor system with unknown load torque disturbance and disturbance inputs, an LMI-based sliding mode control scheme is proposed in this paper. After a brief review of the PMSM mathematical model, the sliding mode control law is designed in terms of linear matrix inequalities (LMIs). By adding an extended observer which estimates the unknown load torque, the proposed speed tracking controller can guarantee a good control performance. The stability of the proposed control system is proven through the reachability condition and an approximate method to implement the chattering reduction is also presented. The proposed control algorithm is implemented by using a digital signal processor (DSP) TMS320F28335. The simulation and experimental results verify that the proposed methodology achieves a more robust performance and a faster dynamic response than the conventional linear PI control method in the presence of PMSM parameter uncertainties and unknown external noises.
Fuzzy Sliding Mode Speed Controller for PM Synchronous Motors With a Load Torque Observer
Viet Quoc Leu,Han Ho Choi,Jin-Woo Jung IEEE 2012 IEEE transactions on power electronics Vol.27 No.3
<P>This paper investigates the robust stabilization problem of a permanent magnet synchronous motor (PMSM). A fuzzy sliding mode speed controller with a load torque observer is designed, which can effectively mitigate chattering and guarantee robust speed control of a PMSM under model parameter and load torque variations. Furthermore, the proposed control method considers the disturbance inputs representing the system nonlinearity or the unmodeled uncertainty. The proposed control algorithm is implemented using a TMS320F28335 floating point DSP. Finally, simulation and experimental results are presented to validate the effectiveness of the proposed scheme.</P>
