The n-hexane extract of Knema pachycarpa fruits (Myristicaceae family), exhibiting strong anti-acetylcholinesterase activity, was investigated by gas chromatography/mass spectrometry and then purified by column chromatography.Guided by GC/MS profiling and bioassay, chromatographic separations led to the isolation of five new compounds: two anacardic acid derivatives 1-2, two cardanol derivatives 3-4 and a cardol derivative 5, along with mixtures of known phenolic lipids 6-9. The chemical structures were determined by various spectroscopic methods. New isolated compounds 1-5 were evaluated for their cytotoxicity and antiacetylcholinesterase activity. Cardanol 3 and cardol 5 were the most active compounds in the acetylcholinesterase inhibitory assay with IC 50 values of 2.60 ± 0.24 µM and 2.46 ± 0.23 µM, respectively. Cardanol 4 and cardol 5 showed moderate cytotoxicity against Hela and MCF-7 cancer cell lines with IC 50 values ranging from 31.36 ± 0.41 µM to 41.30 ± 2.49 µM.

The purpose of this paper aims to identify the components of service quality at specific tourist destinations and the crucial relationship between cultural contact and service quality in the Mekong Delta Region, Vietnam. The paper shows the relationship of tourists’ satisfaction, loyalty, and cultural contact after using the tourism service in the Mekong Delta Region, Vietnam based on qualitative and quantitative research. Data were obtained from 350 tourists, who responded willingly to a questionnaire-based survey. The results of the study show all factors were significant as components of service quality including tourism infrastructure, natural environment, human resources, safety and security, service, and price. All of these components and the cultural contact have an impact on tourist satisfaction and loyalty.

In Vietnam, among 10 biggest economic groups (SEGs), four representatives, which are Viettel, Mobifone (belonged to VNPT in the period 1994-2016), Bao Viet Insurance (belonging to Bao Viet Group), Petroleum Insurance (belonging to PVN Group), have been ranked in the top list of 100 most desired employers in the market by Anphabe. This means that the working environment at the parent company or some subsidiaries of these four groups retains good employees and constantly attracts new talents to join. However, with the great potential and incentives on resources received from the Government, the business performance indicators of those State Economic Groups are not really commensurate. The root of the problem lies in the motivation of the workers. Also, the picture of corporate social responsibility is also much more energetic when the business situation of the groups becomes positive. When international partners and importers require Vietnamese enterprises to comply with global standards on occupational safety, worker health care, and environmental protection, Vietnamese enterprises will have stronger motivation to change and improve their performance, which means increased competitive advantage in the globally integrated environment. Therefore, this paper focuses on the relationship between CSR and the process of motivating employees to suggest new and more groundbreaking research directions on this issue in the future. This study is one of very few studies which have examined the potential relationship between Corporate Social Responsibility and Employee Motivation, with a look from the inside of the company towards the outside connection with society, communities and the customers. The effects can be imposed in back-and-forth directions between CSR and Employee Motivation activities of the company.
