  • Nuclear factor-${\kappa}{B}$ (NF-${\kappa}{B}$) belongs to a group of homodimers and heterodimers of Rel/NF-${\kappa}{B}$ proteins that bind to DNA target sites, where they directly regulate gene transcription. The activation of NF-${\kappa}{B}$ has been shown to mediate inflammation and suppress apoptosis. Activated NF-${\kappa}{B}$ has been found n various inflammatory diseases such as rheumatoid arthritis, Atherosclerosis, asthma, nflammatory bowel disease, and Helicobacter pylori-associated gastritis and associated with cancer, cachexia, diabetes, euthyroid sick syndrome, and AIDS.

  • Đoạn tuyệt is the representative of not only Nhất Linh's literary life but also of the Tự Lực Văn Đoàn [Self-Strength Literary Group]. Đoạn tuyệt's contributions are emphasized in the following aspects: 1) critique of the feudal family model, 2) an advocate of female and individual liberation, 3) nationalistic content, though rather vague. Based on analysis of gender power relations in the masculinization of femininity exemplified in the character Loan of the novel, this paper addresses the following points: - In Đoạn tuyệt, the woman is eager to free herself from feudalist ties not to construct her own identity but to identify her with men's identities. - The construction of new feminine identities was conditioned in new rising discourses of Western modernity-based nationalisms in pre-revolutionary Vietnam. - The feminization of masculinity echoes the crisis of Vietnamese masculine in facing colonial power.

  • This study explores postmodernism in Vietnamese literature. While there has been much dispute among critics regarding postmodernism in Vietnamese literature, postmodernism is now thought to be something that cannot be denied. Vietnamese postmodernism has Vietnamese characteristics and is strongly influenced by American literature. The structure of some Vietnamese short stories is similar to that of some American writers. In the writings of Jean-François Lyotard, Jean Baudrillard and Ihab Hassan, for example, we find out many characteristics which are ascribed to postmodern Vietnamese literature. We propose the use of the term 'Lao Tzu discourse'which is to include the main concepts of postmodernism such as chaos, nothingness and fragmentation. We propose that postmodern Vietnamese Literature appeared in the 1940s with the collection, Fall Spring Poems (1942), and is also seen with the prose of Nguyen Khai and Nguyen Minh Chau in the 1980s, and the drama written by Luu Quang Vu in the 1980s. There now exists a large group of postmodern Vietnamese writers, like Le Dat, Thanh Thao, Bao Ninh, Cao Duy Son, Nguyen Ngoc Tu and Nguyen Binh Phuong, among others.

  • An increasing number of students from different cultures study in higher primary schools. This trend is due to: 1) the government's discourse on increasing the level of participation of foreign students in national educational programs and the need for internationalization; 2) the need of employers for professionals who are trained to work in a multicultural environment to meet the needs of different markets and customers. Methodology. This study is based on the results of the OECD (2018) structured survey of 1,093 teachers at universities in Australia, Colombia, the Czech Republic, Denmark, Georgia, Malta, Vietnam, Turkey, and Argentina, examined policy, the practice of cultural characteristics in training specialists, and teachers' attitudes to cultural diversity. Results. The attitude and perception of cultural features by teachers does not determine the practice of forming a cultural environment and managing this environment to ensure quality education of students of different nations. The main culturological aspects of training are self-expression of cultural and ethnic identities, expression of cultural characteristics and their value through multicultural activities in universities, teaching students to combat ethnic or cultural discrimination. Therefore, the formation of a multicultural environment in higher education occurs through the activities of students and teachers, which complement each other. The practical value lies in identifying two important components of the formation of cultural diversity among students, such as self-expression of ethnic and cultural identity and the expression of cultural differences by teachers in the course of educational activities.

  • In Korea, almost 700 industrial parks are under operation. Generally, industrial parks consist of national industrial parks and local industrial parks which are managed by a central government and by local governments respectively. The developing countries such as Korea, China and Vietnam etc. have constructed many industrial parks, which result in the change of land use pattern and also affect future trip demands. Therefore, in estimating traffic demands, it is very important to consider the industrial park development. This study aims to improve the methodology in estimating a freight trip generation rate with the data based on a nationwide commodity freight survey. The result showed that it is desirable to apply freight trip generation rate by the industry sector in estimating freight trip generations and using the production area of firm as an indicator. Specially, the reliability of the rates through a survey could be made sure because a sample rate based on firms in industrial parks was over 25% and the response rate was over 67%. The sample rate and response rate are very superior as compared to surveys conducted in many other countries. Because industrial parks have significant effects on forecasting transportation demand in pre-feasibility studies of transport and logistics projects, it is expected that the accuracy of freight trip demands would be improved through the results of this study.

  • Vinalines is actually known as not only one of Vietnam's state-sponsored economic giants but also the largest shipowner by tonnage in Vietnamese shipping industry. Therefore, a question of how to improve business performance of the corporation is always received deep attention by Vietnamese government, specially after the seriously economic scandal of Vinalines in a last few years. Among development strategies, the study focuses on short-term one in which Vinalines is recommended to restructure its own fleet in order to optimize performance of fleet operation and minimize costs while meeting the customer's shipping demand in near future. The first section is of introduction. Via method of statistical data analysis, section 2 brings to readers a panorama about the development profile and the current situation of development of Vinalines. In section 3, the authors use linear programming for setting a cost-minimization model optimizing Vinalines fleet structure based on available statistics and forecast information by Vinalines. The optimization problem is solved by applying AIMMS software in section 4. Finally, some conclusions and proposals by authors for the development of Vinalines are given.

  • The Mekong River plays an extremely important role in Southeast Asia. Flowing through six countries, including China, Myanmar, Thailand, Laos PDR, Cambodia, and Vietnam, it is a site of great biological and ecological diversity and the habitat of numerous species of fish. It also supports a very large population that lives along the river basin. Therefore, much attention has been focused on the giant Mekong River Basin, particularly, its soil erosion and sedimentation problems. In fact, many methods have been used to calculate and simulate these problems. However, in the case of the Mekong River Basin, the available data is limited because of the extreme size of the area (about $795,000km^2$) and lack of equipment systems in the countries through which the Mekong River flows. In this study, we applied the Universal Soil Loss Equation (USLE) model in a GIS (Geographic Information System) framework to calculate the amount of soil erosion and sediment load during the selected period, from 1951 to 2007. The result points out dangerous areas, such as the Upper Mekong River Basin and 3S Basin (containing the Sekong, Sesan, and Srepok Rivers) that are suffering the serious consequences of soil erosion problems. Moreover, the present model is also useful for supporting river basin management in the implementation of sustainable management practices in the Mekong River Basin and other basins.

  • The paper examines the characteristics and causes of the expectation gap of audit and assurance services. The paper has conducted three surveys with three target groups. In the first survey, participants are auditors, users of audit reports are subject in the second survey and in the third survey, and students major in auditing are selected. The content of the survey aims to find out the differences in perception of the survey participants on two issues: (i) responsibilities of auditors for detection frauds, errors, protection of the enterprise's assets and financial scandals, and (ii) the role of audit and auditors in making investment decisions and investor's belief. The research carried out survey from March to September 2019 with 165 responds. The collected data was processed by statistical software SPSS, version 23, and Mann-Whitney U test was used to analyze the results of the audit expectation gap between the auditor group and the users of audit report group and between the student group and users of audit report group. The results showed that there exists an expectation gap in the responsibility of auditors for detection of all frauds, errors and protection enterprise's assets. Recommendations include strengthening audit standards, penalizing bad practices and ensuring auditor's independence.

  • During the period of past fifteen years (1992~2006), variations of chlorophyll a in relation with water quality in freshwater reservoirs were investigated. This study compared total nitrogen (TN), total phosphorus (TP), chlorophyll a, Secchi depth (SD) and total suspended solids (TSS) between terrestrial freshwater reservoir and coastal freshwater reservoir systems based on their location. Regression analyses (linear and non-linear regressions) were applied for all study sites to examine relationship and interaction of these factors in the freshwater systems from in-land to coasts. The results demonstrated that chlorophyll a was significantly correlated to total phosphorus ($R^2=0.94$, P<0.0001) and was remarkably related to TSS increase ($R^2=0.63$, P<0.0001) in the selected reservoirs. The TN : TP ratio in the reservoir systems was higher than Redfield ratio (16 : 1) indicating that the reservoirs are potentially experiencing P limitation. Water quality of coastal freshwater reservoir system was more significantly decreased than the reservoirs located in in-land during the past fifteen years. The strict management of nutrient discharge into freshwater systems should implemented in the coastal reservoirs since the freshwater is introduced into coastal estuarine systems.

  • The paper investigates the mechanism through which corporate credit ratings affect dividend payments by decomposing the mean difference of dividends into a part that is explained by the determinants of dividends and a residual part that is contributed by the pure credit group effect, in the framework of the traditional dividend model of Fama and French (2001). Historically, better credit rated firms have shown consistently higher propensity to pay dividends especially during the economic crisis period. According to the counter-factual decomposition technique of Jann (2008), better rated firms are more responsive to the firm characteristics that have positive impact on dividends and poor rated firms are more responsive to the negative dividend predictors. As a result, good (bad) credit ratings make corporate managers become more bold (timid) in their dividend payments and they tend to pay more (less) dividends than what their firm characteristics prescribe. The degree of information asymmetry increases for the poor group firms during crisis periods and they attempt to reserve more cash in preparation for future investments. The decomposition results suggest that the credit group effect can potentially exceed the effect of firm characteristics because firms of different credit ratings can respond to the very same firm characteristics in a different manner.
