ORGANIZATIONAL CULTURE OF ENTERPRISES IN THUA THIEN HUE PROVINCE WITH DENISON MODEL

Abstract: Nowadays, businesses recognize that organizational culture has played a particularly important role in the organization's success. This study aims to identify the cultural traits of enterprises in Thua Thien Hue province by applying the Denison organizational culture model. The results show that the organizational culture of enterprises in Thua Thien Hue province is an internal focus and in a stable and flexible balance. In addition, “Involvement” is the strongest trait, and “Adaptability” is the weakest trait of Thua Thien Hue’s enterprises. Among the 12 indices of the Denison organizational culture model, the index “Team orientation” has the highest score, while “Creating change” and “Agreement” have the lowest. These are important findings for managers to identify the strengths and weaknesses of the organizational cultural system. They can set priorities for adjustment to improve the organizational culture and enhance the competitiveness of enterprises in Thua Thien Hue province.Keywords: organizational culture, Denison mode

FREE VIBRATION ANALYSIS OF POROUS NANOPLATES USING NURBS FORMULATIONS

This paper presents free vibration analysis of functionally graded (FG) porous nanoplates based on isogeometric approach. Material properties of the nanoplates are given by using a modified power-law function. The Eringen’s nonlocal elasticity is used to capture the size effects. Based on a combination of the Hamilton’s principle and the higher order shear deformation theory, the governing equations of the porous nanoplates are derived. The obtained results demonstrate the significance of nonlocal parameter, porosity volume fraction, porosity distributions and volume fraction exponent on free vibration analysis of the nanoplates with porosities

FABRICATION, EVALUATION OF DRUG LOADING CAPABILITY AND CHARACTERIZATION OF 3D-NANO-CELLULOSE NETWORK MATERIALS PRODUCED BY BACTERIA OF FERMENTED AQUEOUS GREEN TEA EXTRACTIN SELECTED CULTURE MEDIA

Objective: The study aims for the fabrication, evaluation of drug loading capability and characterization of 3D-nano-cellulose network materials produced by bacteria of fermented aqueous green tea extract in selected culture media. Methods: 3D-nano-cellulose network (3DNC) materials can be produced by bacteria living in a fermented aqueous green tea extract. 3DNCs include nano-fibers forming networks, which are capable of drug loading to form a prolonged release therapy to improve drug bioavailability. In this study, 3DNC materials are biosynthesized by aerobic bacteria in the standard medium (SM), coconut water (CW) and rice water (RW). 3DNCs were prepared and evaluated for drug carrier using famotidine as a model drug. Famotidine was loaded in 3DNC by the absorption method. 3DNCs were characterized by using FE-SEM and FTIR spectroscopy. Results: The 3DNCs obtained from CW, and RW have the same characteristics as the 3DNC obtained from the SM, and 3DNCs can be fabricated with the desired thickness and diameter in all three types of culture media. 3DNCs absorbed famotidine in optimum condition without any difference in famotidine loading (28.2 mg) and famotidine entrapment efficiency (90 %). Investigation of the 3DNC structure using FE-SEM has shown that the cellulose fibers of 3DNC-SM and 3DNC-CW have a stable structure without structural change when loading drug under optimal condition. Conclusion: The results indicate the potential for using 3DNC-SM and 3DNC-CW to design the drug delivery system
