This study seeks to examine the relationship between business resources (through VRIN: Valuable - valuable, Rare - scarce; Inimitable - difficult to adapt, Irreplaceable - hard to replace), dynamic capability, external cooperation, and efficiency of startups operating in the seafood export sector. Research data was collected randomly and conveniently from 250 enterprises in Ba Ria-Vung Tau province, Vietnam, from October 2020 to December 2020. After excluding those ineligible, the remaining 204 enterprises meet the research conditions. With the support of SPSS-AMOS 22 dedicated software, using the 5-step Likert scale and Structural Equation Modeling (SEM), the study conducted analysis steps such as verifying convergence, discriminant value, unidirectional and scale reliability when giving the components correlated freely in the critical model by Confirmatory Factor Analysis (CFA) analysis. Results of the study have shown that the enterprise resource factor - VRIN has a positive impact on dynamic capability, and outside cooperation. However, in contrast to previous studies, we found that the relationship between enterprise resources - VRIN and performance as well as the relationship between dynamics capacity and performance is not clear. This shows that seafood exporters need to promote, exploit and effectively use this precious resource to improve business efficiency.

Phuong, Nguyen Thi,Anh Ho, Viet,Hai Nguyen, Dai,Khoa, Nguyen Cuu,Quyen, Tran Ngoc,Lee, Yunki,Park, Ki Dong Technomic Pub. Co 2015 Journal of bioactive and compatible polymers Vol.30 No.4

<P>Oxidized polysaccharide-based hydrogels have recently attracted much attention for tissue regeneration because of their biocompatibility and tissue-adhesive property. In this study, we introduce a new type of chitosan-based hydrogel as a tissue sealant, which was prepared by enzymatic mediation from periodate-oxidized chitosan–polyethylene glycol–tyramine. The oxidized chitosan backbone was expected to enhance the interconnection between the hydrogel layer and collagen in the tissues via the Schiff-base reaction. Proton nuclear magnetic resonance spectra indicated that tyramine-functionalized polyethylene glycol-nitrophenyl carbonate ester was conjugated to the oxidized chitosan. The degree of oxidation of the chitosan backbone was around 14% of the glucosamine units by proton nuclear magnetic resonance. The hydrogel was rapidly formed in situ (within a few seconds) in the presence of horseradish peroxidase and hydrogen peroxide. In vitro experiments with live/dead cell assays showed that the oxidized chitosan-based hydrogel was cytobiocompatible. The hydrogel exhibited high tissue adhesion strength on porcine skin models as well as good tissue-adhesive ability and wound healing properties on rabbit skin. These positive results could be promising for the application of oxidized chitosan-based hydrogels as a wound sealant.</P>

The purpose of this study was to examine the effect of two-dimensional factor of motivators and hygiene on civil servants’ job satisfaction using the partial least square structural equation modeling (PLS-SEM) as a technique employed to analyze the measurement and structural models. Exploratory study was deployed to evaluate the relationship among variables. By using multistage stratified sampling, statistical data was collected from a survey of 441 public municipal civil servants who have employed in various levels (municipal government, districts and communes) in Vietnam. The findings provided evidence that hygiene factors (relationship with leader, salary, relationship with coworker and working environment) directly impact on civil servants’ job satisfaction. Meanwhile, only career development factor from motivators significantly influenced on public employee’s job satisfaction. Based on the empirical results, the hygiene factors of job satisfaction are more dominated that the motivators one. This finding suggests that municipal governments should focus policies on improving the hygiene factors which lead to higher job satisfaction on civil servants. Gaining a thorough understanding of the determinants of job satisfaction toward municipal public servants will enable policy makers to grasp the factors that results in retaining employees. Finally, the policy makers can use this knowledge to promote civil servants’ job satisfaction.

본 연구는 폐쇄형 식물공장에서 시금치 수경재배시 세가지의 인공광이 생육, 광합성 및 품질에 미치는 영향을 규명하기 위해 수행되었다. 세가지 광 처리구는 적색 (660nm), 청색 (450nm) 및 녹색 (550nm) LED를 사용하여, R660 / B450 = 4/1 (RBL), R660 / B450 / G550 = 5/2/3 (WWL); R660 / B450 / G550 = 1/1/1 (WL) 비율로 혼합하였고, 동일한 광도로 설정하였다 (PPFD = 190 μmol‧m<SUP>-2</SUP>‧s<SUP>-1</SUP>). 생육조사결과 초장, 엽수는 WL이 가장 적었다. SPAD, 순광합성율, Fv/Fm, LAI, 근권부 생육은 RBL이 가장 높았고 통계적으로 유의하였다. 줄기, 잎, 뿌리의 생체중, 뿌리의 건물 중은 세가지 처리구에서 유의한 차이를 보였다. 대조적으로 WL의 칼륨의 함량은 WWL과 RBL 가운데 가장 높았지만, 반면 칼륨과 철의 함량은 RBL이 가장 높았다. 비타민C 함량도 시험구간 유의한 차이를 보였다. 질소와 옥살산 함량은 WL이 가장 높았고, 용해성 고체와 비타민C 함량은 RBL이 가장 높았다. 옥살산, 질소 함량은 WWL에서 감소하는 경향을 보였고, RBL의 옥살산 함량은 WL와 WWL과 차이가 없었다. 모든 처리구에서 Salmonella, E.coli. 는 감염되지 않았다. 결론적으로, RBL이 시금치의 생육에 적합하지만, 적색, 청색과 적정하게 혼합된 녹색광은 시금치의 생육에 긍정적인 영향을 미친다고 판단된다. The effect of three different light qualities on growth, photosynthesis, quality and safe parameters of hydroponic cultivated spinach (Spinacia oleracea L.) were investigated indoor. Three different light qualities were created of red (660 nm), blue (450 nm) and green (550 nm) LEDs corresponding at ratio R660/B450 = 4/1 (RBL); R660/B450/G550= 5/2/3 (WWL); R660/B450/G550 = 1/1/1 (WL), which were tested at the same intensity (PPFD =190 μmol m-2 s-1). The results showed that the plant height and leaf number were the lowest in WL treatment. The SPAD, Net photosynthesis rate Pn, Fv/Fm, Leaf area index LAI values and all parameters of root characteristics were the highest in RBL treatment and were significantly different from two others. Fresh weight of stem, leaf and root, dry weight of root in the three light qualities were significantly different. In contrast, the highest K<SUP>+</SUP> content in WL was different from WWL and RBL treatments, while Ca<SUP>2+</SUP> and Fe<SUP>2+</SUP> content were the highest in the RBL treatment. Vitamin C content was significantly different between the three treatments. nitrate and oxalic acid contents were the highest in WL treatment, whereas soluble–solids contents and vitamin C contents were the highest in RBL treatment. Oxalic acid, nitrate contents were observed tending reduced under WWL although oxalic acid content in RBL treatment was not different from WL and WWL treatments. In all three different light treatments were not detected Salmonella, E.coli. Our results suggest that RBL may be appropriate light for growth of spinach, but supplementary green light to a combination of red and blue LEDs at the reasonable rate can change the quality of spinach in a positive direction. Hydroponic cultivated spinach was safe for users.

PHUONG, Nguyen Ngoc Duy,LUAN, Ly Thien,DONG, Vu Van,KHANH, Nguyen Le Nhat Korea Distribution Science Association 2020 The Journal of Asian Finance, Economics and Busine Vol.7 No.9

The purpose of the research is to identify antecedents of mobile wallet continuance intention in Vietnam. A self-administered questionnaire was distributed to collect data from a total of 276 respondents. Partial least squares structural equation modeling was employed for analyzing the data. Five mobile wallet features - mobile application quality, mobile wallet familiarity, situational normality, payment security, and feedback mechanism - are introduced as fundamental elements, which influence customer' continuance intention to use mobile wallet in Vietnam. The results indicate that mobile quality application and familiarity can significantly influence perceived ease-of-use (PEOU) and perceived usefulness (PU), but situational normality has an impact only on PEOU. PEOU and PU are positively related to satisfaction. On the other hand, payment security and feedback mechanism affect positively customer' trust. As a result, the positive effects that satisfaction and trust have on electronic wallet continuance intention are confirmed. The findings can be used to advise mobile wallet providers to improve their platform design and services to retain users. As a theoretical contribution, this study combines the Technology Acceptance Model, Unified Theory of Acceptance and Use of Technology to investigate the key determinants on continuance intention in the context of electronic wallet in Vietnam.

Phuong Ngoc Duy NGUYEN,Linh Le Khanh NGUYEN,Dong Nguyen Thanh LE 한국유통과학회 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.8

The purpose of this study is to explore the link between job satisfaction and organizational commitment at higher education institutions (HEIs) in emerging countries such as Vietnam and to determine extrinsic work factors that influence job satisfaction. Higher education is critical for socio-economic growth and the overall development of each country. Hence, an understanding of what motivates employees’ actions and attitudes should be obtained before determining the extent of employee satisfaction. The conceptual model was developed by incorporating job satisfaction-related variables, their relationships, and the impact of job satisfaction on organizational commitment. An empirical study was conducted on a study sample of public and private universities, with 316 academics and non-academic employees surveyed. The current study employed the partial least squares structural equation modeling to test the proposed hypotheses. The results reveal a positive and significant relationship between job satisfaction and organizational commitment. The findings confirm that extrinsic work factors (job itself, supervision, working conditions, payment, and reward and recognition) have a positive and significant relationship with job satisfaction. Furthermore, the study indicates that employees at HEIs who have a high level of ability utilization and supervisor support are more likely to be satisfied with their jobs.

Nguyen Ngoc Duy Phuong,Mai Ngoc Khuong,Thai Hoang Quoc,Le Nguyen Thanh Dong 한국유통과학회 2017 KODISA ICBE (International Conference on Business Vol.2017 No.-

The purpose of this study was to examine the direct and indirect effect of ethical leadership, organizational justice, organizational support on employee satisfaction and employee engagement. Very little research has been conducted to study those relationships in the socialization context. This paper attempts to fill the gap by analyzing data from a survey of 677 employees from industrial parks. This study used a survey instrument that consists of 2 sections. To ensure content validity, the survey items were derived from those used in previous studies. Each item was measured using a 5-point Likert scale. Ethical leadership scale with ten items were adopted from Toor and Ofori (2009). Partial least square structural equation modeling (PLS-SEM) is employed for testing the structural models and exploratory study is also identified to evaluate the relationship among variables. The findings provided evidence that employee satisfaction is the most important to predict employee engagement. The results also reveal the important effect of ethical leadership, organizational justice and supporting environment on job satisfaction. Implications for public policy practice and further research are also suggested based on the results of structural analysis.

Organizational Justice, Job Satisfaction and Organizational Citizenship Behavior in Higher Education Institutions: A Research Proposition in Vietnam

Le Nguyen Thanh Dong,Nguyen Ngoc Duy Phuong 한국유통과학회 2018 The Journal of Asian Finance, Economics and Busine Vol.5 No.3

Higher Education Institutions (HEIs) are place contributing to the intellectual advancement of the nation, quality human resource, and to a number of socio-economic improvements for society and organizations. Despite facilitators and staffs are the bare-bone of HEIs, there is a scarcity of research, both conceptual and empirical, focusing on their organizational citizenship behaviors (OCB). To attempt to fill this gap, this article develops a conceptual model of OCB under influencing of organizational justice and job satisfaction. The prospective respondents were chosen randomly from HEIs (public and private). Individuals have been employed at least one year and above will be the unit of analysis in which the experimental test of the proposed model will be conducted. The results suggest that organizational citizenship behavior is one of the most important factor influence the organizational performance. Furthermore, the performance of HEIs does not affect only the national human resources, but also impact on national economy. In this context, a conceptual framework is proposed to study the determinants of organizational citizenship behavior in the form of organizational justice and job satisfaction. Additionally, the ultimate benefits of OCB through perceived organizational justice with job satisfaction as mediator is enlightened. Finally, the authors discuss the managerial implications of their research.

Higher Education Institutions (HEIs) are place contributing to the intellectual advancement of the nation, quality human resource, and to a number of socio-economic improvements for society and organizations. To achieve the objectives of the study, the structural equation modeling, particular, a partial least square method (PLS) is suitable since this techniques permits the simultaneous estimation of multiple equations and performs factor analysis including regression analysis. Despite facilitators and staffs being the bare-bone of HEIs, there is a dearth of research, both conceptual and empirical, focusing on their perceived of organizational justice and its impact on employees’ job satisfaction, organizational commitment, organizational citizenship behaviors (OCB). To attempt to fill this gap, this article develops a conceptual model on OCB with the organizational justice the influence of the job satisfaction on the organizational commitment and OCB. OCB is one of the most important factor influence the organizational performance. Furthermore, the performance of HEIs will does not effects only the national human resources, but also impact on national economy. Finally, the authors discuss the managerial implications of their research and offer guidelines for future empirical research.
