Daoism was introduced into the South-West of Vietnam via two main entries: the missionaries from North and Central Vietnam who migrated to the South by following the Southward movement and the spread of Daoism by Chinese migrant men who came and settled in the South-West of Vietnam from the late seventieth century to late nineteenth century. However, the biggest influence of Daoism in the Southwest of Vietnam was mainly the Chinese missionaries of Daoism. As time went by, together with the impacts of social and historical circumstances, Daoism had a strong influence on the lives of the South-West people in terms of different aspects, especially their faith and religions. The impact of Daoism into people's faith and religion was considerable, especially to the indigenous religions, of which the religion, Four Debts of Gratitude, is a representative example. With the aims of clarifying how Four Debts of Gratitude was influenced by Daoist thought and how the indigenous religions and systemized ideologies in the South-West of Vietnam were related during the period of living condition expansion as well as cohabitation of several ethnic groups in the region, this article focuses on Daoist thought expressed in typical symbols in the sacred architecture of the Four Debts of Gratitude such as Cổ Lầu, wine gourds, and the Eight Trigrams. Once properly examined, it becomes clear that the prominent symbols and other Daoist elements show that Daoism had a profound influence on the Four Debts of Gratitude.
The Role of State Budget Expenditure on Economic Growth: Empirical Study in Vietnam
Hieu Huu NGUYEN 한국유통과학회 2019 The Journal of Asian Finance, Economics and Busine Vol.6 No.3
Many authors have examined the impact of public spending on economic growth. This study uses ordinary least-squares technique to test the effect of state budget expenditure with two major components: development investment expenditure and recurrent expenditure on Vietnamese economy for the period 2000-2017. The empirical results show that the state budget expenditure of Vietnam has positive effect on the economy, however each main component has different impacts. Recurrent expenditure has significant positive impact on Vietnamese economy while there has no evidence to affirm the relationship between the development investment expenditure and the economic growth. Vietnamese government should restructure the state budget to enhance the positive effect on the economy. In the short run, Vietnam should not increase development investment expenditure due to low efficency in public investment. In the long run, it is necessary to economize recurrent expenditure to reserve a reasonable proportion of state budget for development investment expenditure to build infrastructure for developing the economy. The state budget expenditure should be restructured towards prioritizing recurrent expenditure on human and social relief, reducing public administration expenditure, allocating investment capital from the state budget for key and pervasive projects, avoiding spreading out investments as well as crowding out private investments.

The Impact of State Budget Revenue on Economic Growth: A Case of Vietnam
Hieu Huu NGUYEN 한국유통과학회 2019 The Journal of Asian Finance, Economics and Busine Vol.6 No.4
This paper is intended to study the relationship between state budget revenue and economic growth in Vietnam. The ordinary leastsquares regression method is used with secondary data collected from General Statistics Office of Vietnam in the period of 20002017. Vietnamese state budget revenue includes domestic revenue (excluding oil revenue), oil revenue, custom duty revenue, and grants. The testing result shows that the state budget revenue has a positive correlation with economic growth of Vietnam. However, the components of state budget revenue have different levels of impact on the economy. Domestic revenue and oil revenue are statistically significant and have a positive effect on the economy, while the impact of custom duty revenue and grants on the economy is invisible. Vietnamese state budget revenue should be restructured toward the sustainability and by way of boosting the economy, specifically: (1) Increase the proportion of domestic revenue to state budget revenue and domestic revenue should be based on the ground of production and business activities rather than collection from state-owned assets; (2) Reduce the proportion of custom duty revenue and grants to state budget revenue; (3) Keep the volume and ratio of oil revenue in state budget revenue at an appropriate proportion.

Purpose: The performance of implant surgery in the posterior maxilla often poses a challenge due to insufficient available bone. Sinus floor elevation was developed to increase the needed vertical height to overcome this problem. However, grafting materials used for the sinus lift technique eventually show resorption. The present study radiographically compared and evaluated the changes in height of the grafting materials after carrying out maxillary sinus elevation with a window opening procedure. This study also evaluated the difference between two xenogenic bone materials when being used for the sinus lifting procedure. Methods: Twenty-one patients were recruited for this study and underwent a sinus lift procedure. All sites were treated with either bovine bone (Bio-$Oss^{(R)}$) with platelet-rich plasma (PRP) or bovine bone (OCS-$B^{(R)}$)/PRP. A total of 69 implants were placed equally 6-8 months after the sinus lift. All sites were clinically and radiographically evaluated right after the implant surgery, 7-12 months, 13-24 months, and 25-48 months after their prosthetic loading. Results: Changes of implant length/bone length with time showed a statistically significant decreasing tendency (P<0.05). There was no significant change in the Bio-$Oss^{(R)}$ group (P>0.05). In contrast, the OCS-$B^{(R)}$ group showed a significant decrease with time (P<0.05). However, no significant difference was observed between the two groups (P>0.05). Conclusions: The results showed that there was significant reduction in comparison with data right after placement, after 7 to 12 months, 13 to 24 months, and over 25 months; however, reduction rates between each period have shown to be without significance. No significant difference in height change was observed between the Bio-$Oss^{(R)}$ and the OCS-$B^{(R)}$ groups.

<P><B>Abstract</B></P><P><B>BACKGROUND</B></P><P><B>Insect olfactory organs possess many olfactory receptor neurons, which detect many different sets of odorants in nature. In order to feed on blood meals, stable flies locate host animals and humans using chemical cues such as 1‐octen‐3‐ol and butyric acid. In the present study, behavioural and electroantennogram (EAG) response patterns to repellent volatiles from essential oils (EOs) of <I>Zanthoxylum piperitum</I> and <I>Z. armatum</I> in combination with the attractants were investigated</B>.</P><P><B>RESULTS</B></P><P><B>Components of the EOs such as cuminaldehyde, citronellal, neral, linalool, linalool oxide, terpinen‐4‐ol, 1,8‐cineole, and piperitone induced remarkable repellent behaviours in the stable fly. EAG responses in the fly antenna to these chemicals showed a dose‐dependent manner. The patterns of behavioural and EAG responses were significantly altered depending on the ratios of 1‐octen‐3‐ol or butyric acid to the EOs or compounds in the air mixtures</B>.</P><P><B>CONCLUSION</B></P><P><B>The present study demonstrated that the <I>Zanthoxylum</I> EOs decreased the levels of response of flight behaviours of the stable fly towards host volatile compounds. The combinations of odorant mixtures of the attractants with the EOs and their components affect the representation of behavioural and EAG responses of the flies. The summation and integration patterns of olfactory responses measured by the EAG indicated that the peripheral olfactory networks in antennae could process the odorant complexity of different odorant mixtures between attractants and repellents. © 2013 Society of Chemical Industry</B></P>
