Coffee is among the favorite drinks in Vietnam and many other countries. Production and consumption of coffee have released a huge amount of spent coffee ground. This study aimed to determine phenolic acids and fatty acids of spent coffee grounds collected in Ho Chi Minh city and how phenolic acid profile was affected by different environmentally friendly extractants. The results showed that average level of chlorogenic acid in ethanol/water extracts (840.4 779.9 ug/g) was significantly higher compared to water extracts (300.0 ug/g). Furthermore, the average total level of phenolic acids in ethanol/water extracts (1215.3 ug/g dry weight) was greater than that in the water extracts (779.9 ug/g dry weight). This indicated that ethanol/water outperformed water in regard to extraction of phenolic acids in the spent coffee grounds. Oil extracted from the spent coffee grounds was rich in linoleic acid (61 ug/g) and palmitic acid (47 ug/g). The findings of our study showed that the spent coffee grounds originating in Vietnam are a good source of phenolic acids and polyunsaturated fatty acids that could be utilized for food and nutraceutical production.

Dai Dao Tam Ky Pho Do [The Great Way of The Third Amnesty Era] (shortly Caodaism) is an indigenous religion established in southern Vietnam in the early 20th century. Being one of the new religions in the region, Caodaism has been constantly developing and attracting quite a great number of followers of over three million. The doctrine of Caodaism is a synthesis of the Three Religions, e.g. Confucianism, Buddhism and Taoism together with elements from some other religions. The doctrine is not only shown in scriptures, religious structure, but also expressed through symbols in architecture, rituals and costumes. To a certain extent, it is thus essential to understand the symbolism of the Holy Temple – the most important one of the symbolism system so that we can fully comprehend Caodaism. The Temple is the most solemn and sacred place in Cao Dai Tay Ninh Holy See. It carries both philosophical and esoteric meanings as an emblem of cultural syncretism. The study of the Holy Temple symbol will elaborate further Caodaist doctrines in a relationship with the cultural context of the Southern region.

Globalization is defined as the free movement of goods, services and people of the worldwide scope across the borders of countries, resulted from the opening up of the global economy and advances of technologies. The increasing interconnectedness and integration of the economies of the world furnish more influx of information among countries which do not have anything in common and Internet and social media well contribute to such spread. Not only the pros but the cons of globalization are used to explain the part of localization as the entire process of adapting a product or content to a specific location or market. The paper indicates localization as the Vietnamese people’s endeavor to adapt Vietnamese language to the world while protecting and enhancing the national characters. The differences between localization and globalization are analyzed to demonstrate the value and requirements of localization in the present time. The influences of Sino-Vietnamese and French language are also found out as evidences of the phenomena. The changes of Vietnamese language from globalization and localization are illustrated with devices, ideas and images referring to the objects, actions or ideas.

In the late nineteenth and early twentieth century, the intelligentsia of the colonial countries and ones being threatened by Western colonial dominance in Asia began to re-perceive the problems of sovereignty, nation-state, and re-ask questions like "What is history for?" as well as review what previous historians wrote about their national history. From re-realizing history and rewriting history according to new perspectives, historiography in these countries has shifted from "traditional" to "modern" with taking Western science as the main direction. Vietnamese historiography is also not out of that general change. Examining the product of historical books at the beginning of the twentieth century, Phan Boi Chau is considered as the pioneer historian for that historiographical turn. The article focuses on analyzing the new historical viewpoints of Phan Boi Chau from the global perspective of the flow of thought in Asian countries at that time.
