Ficus hispida L.f. (FH) is among the widely cultivated tree species in Asian regions. The aim of this work was to determine phenolic and flavonoid contents, antioxidant, in vitro anti-inflammatory activities of FH extracts prepared with methanol (ME), ethanol (ET) and ethyl acetate (EA). The extract obtained from ethyl acetate contained the highest total phenolic and flavonoid contents (92.75 +/- 5.14 mg GAE/g and 5.67 +/- 0.65 mg QE/g), followed by ME and ET. The capacity to scavenge ABTS free radical of the extracts followed the order: EA > ME > ET while their DPPH activity differed insignificantly. The inhibitory effect of EA and ME (IC¬50 = 362.84 +/- 29.05 and 386.95 +/- 11.10 ug/mL, respectively) were higher than that of ET. Correlation analysis showed a high positive correlation between total phenolic content and ABTS activity. The findings of the study would be useful for development of new nature-derived agents for prevention and treatment of diseases.

It is very common to stabilize the preset value (Wanted value) of analog signals such as temperature, pressure, weight, flow, speed in automatic control. However, these control objects often have some problems such as overshooting, taking a long time to bring the system to a steady value, and large errors. One of the most used systems to overcome these problems is the PID, which is a preset stabilizing system with a quick function that returns the system to the set value in a short time without overshooting. error is close to zero. However, determining the scale parameters Ki, integral Kp, and differential Kd for the system to work optimally is a problem that needs to be studied. This paper presents how to accurately determine differential, integral, and scale coefficients according to 3D virtual reality model. Used a lot in simulation modeling for training and practical applications.

Since 2017, the United Nations has strengthened the economic sanctions on North Korea. Many countries have stopped trading with North Korea, causing the economic certain difficulties. China has become a trade and tourism partner that accounting for almost all of the country's foreign currency earning. That had gone on until the beginning of 2020 when North Korea locked its borders to avoid the Covid-19 epidemic. North Korea is essentially famous for having published a quite relatively little information about themselves and being nicknamed “The Hermit Kingdom” due theirs policies. Therefore, the article will analyze mirror data from countries, then compare it with the actual situation of North Korea to assess the reliability of the data. Moreover, providing information on transport routes that is major contributor to China-North Korea. Thereby, drawing comments on China-North Korea merchandise trade and tourism industry relationship in that stage and proving North Korean economic adaptation under International sanctions.

Binh Duong has rapidly transformed during the period 1999-2009, from a agricultural province to industrial one. The paper explores the shift of occupation-based social structure of Binh Duong during that period. Using the data sets of Census 1999 and 2009, the paper analyses the evolution of the occupational figure in Binh Duong by ten occupational categories and four occupational strata, and the differences in this figure by residence, gender, ethnic, and religious variables. Findings show that the occupational structure of Binh Duong is more developed than the one of the Southern Key Economic Zone. Its change in rural areas is more significant than in urban areas. There are not considerable differences by gender, ethnicity, and religiousness. The findings are suggestive for a further analysis using the data set of Census 2019 on the evolution of occupational figures in Binh Duong during the previous twenty years (1999-2019).
