Factors Affecting Cooperation in the International Supply Chain of Seafood Enterprises: the Case of Vietnamese
Purpose: The purpose of this research is to analyze and evaluate factors affecting cooperation in the international supply chain of Vietnamese seafood enterprises.
Theoretical framework: Operations in international business context are associated with high risks, so cooperation in supply chain helps to improve management flexibility. On the other hand, acccording to the theory of resource dependency, resource sharing and information sharing strategies can affect the quality and the level of cooperation among supply chain partners.
Design/methodology/approach: To achieve the aim of this study, a literature survey related to supply chain and supply chain cooperation is carried out, and empirical analysis is conducted among 327 partners in seafood industry with the results analyzed using Cronbach’s Alpha analysis, exploratory factor analysis (EFA), and linear regression analysis (RA).
Findings: Research results have confirmed that there are six main factors directly affecting the international supply chain cooperation of Vietnamese seafood enterprises including: (1) Trust; (2) Power; (3) Distance; (4) Government policy; (5) Cooperation strategies and (6) Information sharing.
Research/Practical & Social implication: The encouraging policies and simplified export regulations are to be implemented by the government, VASEP and enterprises so the knowledge about international supply chain cooperation will be promoted with the help of comprehensive future research directions.
Originality/value: This is literally one of the first research works in Vietnam to incorporate the information sharing component into the model of affecting factors for international supply chain cooperation. Regardless of business uncertainties, the study shed new light on supply chain cooperation and promote firms to gain an edge in the global marketplace
HOẠT HÓA THAN BÙN ĐỂ XỬ LÝ ION Cd2+ TRONG DUNG DỊCH NƯỚC
In this study, peat was activated with H3PO4 at a concentration of 2.0 M. The synthesized samples were characterized by several methods such as EDX, XRD, SEM, BET and FTIR. The adsorption properties of the materials were evaluated through their ability to remove Cd2+ ions in aqueous solution. Material characteristics show that the peat sample after activation has a higher specific surface area and porosity than the raw peat sample. The study shows that experimental data of Cd2+ ion adsorption on activated peat is well described simultaneously by both Langmuir and Freundlich isotherm models, however the Langmuir isotherm model appears to be more suitable. The activated peat material reached the maximum adsorption capacity qm 29.07 mg/g. In addition, the study also shows that the adsorption of Cd2+ ions on activated peat follows the apparent second-order kinetic model. From the above research results, it shows that adsorbent materials from peat have great potential in remove heavy metal ions in aqueous solution.Trong nghiên cứu này, vật liệu nghiên cứu là than bùn được hoạt hóa bằng H3PO4 ở nồng độ 2,0 M.

Đặc trưng vật liệu cho thấy mẫu than bùn sau khi hoạt hóa có diện tích bề mặt riêng và độ xốp cao hơn so với mẫu than bùn thô. Nghiên cứu cho thấy dữ liệu thực nghiệm hấp phụ ion Cd2+ trên than bùn được hoạt hóa được mô tả tốt đồng thời bởi cả hai mô hình đẳng nhiệt Langmuir và Freundlich, tuy nhiên mô hình đẳng nhiệt Langmuir tỏ ra phù hợp hơn. Vật liệu than bùn được hoạt hóa đạt dung lượng hấp phụ cực đại qm 29,07 mg/g. Ngoài ra nghiên cứu còn cho thấy sự hấp phụ ion Cd2+ trên than bùn hoạt hóa tuân theo mô hình động học biểu kiến bậc 2. Từ những kết quả nghiên cứu trên cho thấy vật liệu hấp phụ từ than bùn có nhiều tiềm năng trong việc loại bỏ các ion kim loại nặng trong dung dịch nước
Stressors, stress levels and attitude toward midlife of Vietnamese female religious and single lay mid-lifers
This study investigates the stressors, stress level and attitude toward midlife of female mid-lifers including religious and single lay female. It aims to determine which among these dimensions namely physical, environmental, occupational and social family is the common stressor of two groups. It also explores the difference in stress level between female religious and single lay female mid-lifers. It attempts to determine the relationship between stress level and attitude toward midlife.The descriptive research design was used. Data were collected through the use of four (4) instruments: Source of Stress Inventory, Stress Level Inventory, Attitude toward Midlife Inventory and eight (8) open-ended questions to confirm the Attitude toward Midlife Inventory. The research participants were 42 female religious mid-lifers from the Lovers of the Holy Cross and 40 single lay female mid-lifers from three (3) selected parishes in Ho Chi Minh City, Vietnam. They were between 35-45 years of age. Mean and standard deviation were computed to obtain the common source of stress, level of stress and attitude toward midlife. T-test was used to determine the differences of stress level of the two groups. The results showed that the environmental dimensions was the most common stressor of the two groups.
It confirmed the hypothesis that female religious had high stress levels than single lay females. Although female mid-lifers had average stress level, they had positive attitude toward midlife. The difference in the attitude toward midlife of the two groups was not found to be significant
Filial piety and family relationships of two generations of Vietnamese parents
This study investigated the concept and indicators of filial piety and family relationship among two generations of Vietnamese parents using a qualitative research design with in-depth interview and case study. The participants of the study were ten households, each consisting of a first generation of parents and a second generation of parents. The study found that filial piety was practiced in both generations even today. Three theme clusters were arrived at namely customary, exceptional, and venerable filial piety. Under each theme cluster were several themes. Customary filial piety was defined as symbolic displays of respect towards not only parents but also other elder namely being obedient to parents, gifts offering, greeting parents, using respectful language, and saving the honorable place for parents. Exceptional filial piety consisted of behavior drawing favorable attention and affection to parents, including looking after parents’ mental and physical health, seeking advice of parents, spending time with parents, and serving food and drinks of parents’ choice. Finally, venerable filial piety was shown to be culturally based, such as venerating ancestors and holding parents’ funeral rites. Filial piety practices were reflected in family relationships in which children expressed deep gratitude to their parents for the gift of life, for rearing them and educating them from the past until present. Filial piety was also manifested in hierarchical family relationships where parents and parents-in-law were revered and respected

Antiproliferative, Anti-Inflammatory Activities, and Molecular Docking Studies of Secondary Metabolites from Macrosolen tricolor
In Vietnam, Macrosolen tricolor is used for the treatment of bloating, broken bones, cough, diarrhea, diuretic, rheumatism, and laxative effects. The study aimed to identify the in vitro antiproliferation and anti-inflammation of all fractions and purified compounds from the M. tricolor whole plants, as well as the in silico molecular docking of the potentially cytotoxic compounds. As the results, fractions (MTH.I, MTH.II, MTE.I, and MTE.II) strongly demonstrated antiproliferative properties against three tested cells, MDA-MB-231, RD, and HepG2 (IC50 values ranged from 4.00 ± 0.20 to 70.60 ± 1.44 μg/mL), as well as anti-inflammatory effects (IC50 values ranged from 4.45 ± 0.08 to 23.00 ± 1.18 μg/mL), whereas other fractions meaningfully evidenced selective cytotoxicity and/or anti-inflammation. Therefore, the phytochemical compositions of the active fractions were illuminated, leading to the characterization of eighteen compounds. Compounds (3–5) revealed the most cytotoxic effects towards all examined cells (IC50 values ranged from 6.88 ± 0.12 to 71.64 ± 1.17 μM) and the strongest anti-inflammatory properties (IC50 values of 16.30 ± 0.92, 7.31 ± 0.55, and 9.23 ± 0.60 μM, respectively). Compound 11 showed potential cytotoxicity against MDA-MB-231, RD, and HepG2 cells (IC50 values of 24.42 ± 0.28, 20.60 ± 0.25, and 3.20 ± 0.02 μM, respectively). Furthermore, compounds (4, 5, and 11) interacted with the active site of the apoptosis regulator Bcl-2 protein (PDB ID: 2O2F), were comparable to PAC, and were compatible with their anticancer activity. This project suggests that M. tricolor is a good source of natural antiproliferative and anti-inflammatory agents and contributes to understanding the biological activities of Macrosolen species in traditional Vietnamese medicine
Hepatoprotection and Phytochemistry of the Vietnamese Herbs Cleome chelidonii and Cleome viscosa Stems
The study aims to determine the hepatoprotective effect of n-hexane, ethyl acetate, and methanol extracts of the leaves and stems of two Cleome species against carbon tetrachloride- (CCl4-) induced liver toxicity both in vitro using human hepatoma (HepG2) cells and in vivo in rats as well as the hepatoprotective property of all isolated compounds on HepG2. After 72 h of treatment, at the concentrations of 25, 50, and 100 μg/mL, the methanol of C. chelidonii stems (CCSM) ranged from 18.6% to 20.8%, whereas the methanol of C. chelidonii stems (CVSM) increased from 12.3% to 17.2% cell viability. The results show that CCSM and CVSM significantly expressed in vitro hepaprotective activity on HepG2. Therefore, the animals were daily treated with these extracts at the doses of 15, 30, and 45 mg/kg body weight for 5 days, and CCl4 was injected (2 ml/kg body weight, i.p.) on the 2nd and 3rd days. Levels of aspartate aminotransferase (ALT) and alanine aminotransferase (AST) in the blood were measured and compared to the silymarin control. The treatments with CCSM and CVSM (30, and 45 mg/kg) possessed significant hepatoprotection and were comparable with the activity of silymarin. Further, phytochemical studies of these ones were conducted and led to the identification of eight flavonoids: visconoside A (1), visconoside B (2), quercetin 3-O-β-D-glucopyranoside 7-O-α-L-rhamnopyranoside (3), kaempferol 3-O-β-D-glucopyranoside 7-O-α-L-rhamnopyranoside (4), cleomeside A (5), cleomeside B (6), cleomeside C (7), and quercetin-3-O-[β-D-glucopyranosyl-(1⟶2)]-α-L-rhamnopyranoside 7-O-α-L-rhamnopyranoside (8). Two major flavonoids (1 and 4) displayed significant hepatoprotective property (at the concentration of 100 μM, the prevention percentage values were 66.5% and 74.2%, respectively, compared to the quercetin control, with value of 80.3%)
