The environment, including natural and social ones, is directly or indirectly related to human beings ?lives. It is created around people, governing their lives, and ensuring their development. In their relation with the natural environment and the social one, human beings always create positive and negative impacts. The relation between human beings and environments is considered a dialectical one between nature and society in the firm development of our country, This development still maintains the quality of the environment and keeps the balance between the environment and progress.

Phu Thu is a largest ward that belongs to Cai Rang district with natural area of 2,014.74ha. Economic structure reforms towards industrialization, urbanization and modernization. Nowsaday, Phu Thu has total of 19 urban planning projects. The changing of land use situation on these projects has influenced to residents? living condition and social economic situation of Phu Thu ward. The general objective of the study is to assess the land use efficiency of urban planning projects to socio-economic situation in the Phu Thu ward ? Cai Rang district ? Can Tho City. The study was based on the data collection from field survey, interview and record based on the questionnaires sheets from 117 local people, management boards, the People?s Committee in the study area. The results of study showed that total capital was increased for almost people in the study areas but it was used incorrectly. These were the direct reasons for low investment efficiency. Agricultural labor was shift to work as workers or small business. Beside, unemployment rate is increased due to low skill and education of local labour. Household facililies for urban life was increased, but it was not improved for people in project incompleted areas. Average per-capita income got VND 13 millions after projects, VND 8.5 millions more than before planning, and total local budget was also increased more than 10 times. Infrastructure, communication in the study areas were improved after urban planning projects. The landscape was more beautiful and the economy of the planning areas was restructured in the direction of urbanization, industrialization and modernization.  

Forty-eight bacterial isolates were isolated from thirteen solid and wastewater samples from the milk factories, the cow-milk stations and cow-milk farms. Among 48 isolates, 15 isolates had polyphosphate-accumulating capabilities. Two isolates (LV1&LV8b) had the high polyphosphate- accumulating abilities. These two polyphosphate-accumulating bacterial isolates were chosen to sequence randomly by automatic sequencer, DNA sequencing were compared with GenBank database of NCBI by BLAST N software; the results showed that LV1 isolate was 100% of the identify with Arthrobacter protophormiae 16S rDNA and Arthrobacter sp. M1T8B14 16S rDNA; LV8b isolate was 100% of the identify with Bacillus megaterium strain PPB7 MB7 16S rDNA, strain PPB5 16S rDNA, strain 2008724130 16S rDNA. Applying of two isolates in artificial wastewater treatment with initial concentration PO43- [orthophosphate] 9 ữ 11 mg/l, LV1 isolate reduced down 1.11 mg/l, LV8b isolate decreased down 3.42 mg/l, combined LV1&LV8b reduced to 2.38 mg/l after 3 days.

Economic efficiency in the present study is estimated from the Cobb-Douglas stochastic profit frontier function. The study uses the data collected from a household survey on 479 farms in the Mekong River Delta. Farm household makes an average profit of about 7.8 and 6.3 million dongs in Summer-Autumn and Autumn-Winter crop, respectively. Given the same inputs and prices, profit from the Summer-Autumn crop is 17 - 19% higher than that from the other crop. The average economic efficiency level is 57 and 58% in Summer-Autumn and Autumn-Winter crop, respectively. As a result, the profit loss from inefficiency is about 4.8 and 3.6 million dongs in the two crops. The efficiency level largely varies across farms due to the big gap in farming techniques and the ability of choosing optimal inputs across farms. Therefore, the potential to increase profit and economic efficiency exists as farming techniques are more equally distributed. It is also found that technical training significantly increases profit and so, efficiency of a farm.

Study on migration of the goby (Pseudapocryptes elongatus) was carried out in the coastal area of Bac Lieu province from January to December, 2009. A number of the migrated fish was determined by using the data of catch (in number) and effort (in hour) of bag net fishery by catch per unit effort, CPUE (number of migrated fish/bag net/hour). Results indicated that the goby abundantly follows the tidal currents for migration to sea in January and February meanwhile it was rarely during October to December. The goby migrated to sea two times per month during the full moon (15th day of lunar calendar) and new moon (30th day of lunar calendar) period, in which they mainly migrated during the new moon period. The results also indicated that the goby started to migrate at the size of 116.1 mm in standard length (SL) and the most migrated size was 147.8 mm (SL).  Almost of the migrated goby was examined as unmatured fish. Results also indicated that the water temperature in the research area fluctuated with narrow range; however, the results showed that CPUE in the period of high water temperature was lower than that of the lower temperature. The results also indicated that the goby migrated abundantly when the salinity, current velocity and tidal range were higher.                           

This paper aims to elaborate the importance of using Ho Chi Minh?s ideology about building Vietnamese Communist party spotless and strong contributed to the block of great national unity that lead to final sucessful.

We studied some of Anh Duc?s short stories written from 1963 to 1973 in order to clarify some issues about the land and the people in the south of Viet Nam during the war against American army. Regarding the southern land of Viet Nam, Anh Duc signified the distinctive scenery of the waterway region and its powerful vitality. With respect to the people, Anh Duc focused on describing common people who were rather quiet but had important contributions to the revolution. The elderly, women, and young men with their own ways created the portrait of the heroic Southerners. Through that way, Anh Duc assured his position in the revolutionary literature of the country.

The study aimed to understand K, Ca, Mg and Mn nutrient status in soil. Six soil profiles were evaluated. Soil chemicals were analysed and equilibrium calculated for each nutrient. Results showed that K was not controlled by any minerals in the soil profiles. Cai Lay soil has 20% of illite-clay, but this mineral does not control the solubility of K in soil solution, this indicated that K was refixed by clay. Potasium soil solution is closely controlled by Soil-K. The difference between Soil-K release and K in soil solution varied among soils used in this study and increased by the order of: Cai Lậy Cầu Kè soil =Tịnh biên soil >Mộc Hóa soils and for Mn was Cai Lậy soil > Vĩnh Mỹ soil =Vĩnh Nguơn soil >Cầu Kè soil =Tịnh Biên soil >Mộc Hóa soils. This ranking was found to be similar to the decrease of CEC in the same order, but studying soil nutrient status using chemical equilibra showed another way to approach nutrient supplying capacity from soil.

The cerebral perfusion pressure (CPP) is defined as the mean arterial pressure (MAP) minus the intracranial pressure (ICP), i.e. CPP=MAP-ICP. Consistent maintenance of the CPP is generally accepted as one of the major requirements in the Intensive Care Unit for patients who may have raised ICP, especially for traumatic brain injury patients from traffic accidents. In this study, a method of raising MAP by automatic control of Noradrenaline (NA) infusion is presented for the purpose of regulating the CPP at an adequate level. In general, the Datex AS/3 and Codman ICP express monitoring systems are used to measure the current MAP and ICP of the patient. The CPP is calculated from these values, and then, considered as a feedback to a PID controller. The NA infusion rate is generated to maintain the CPP at a reference level due to the increase of ICP. The control system was tried on regulating the CPP around 70 mmHg on 10 pigs under anaesthesia condition and manual incresement of ICP by an intraventricular balloon catheter. The system response achieves the settling time 5±1.30 min and the overshoot 4±1.72 mmHg. The results indicated the feasibility of the CPP control system.

The objective of the study is to assess financial efficiency of rice monocultural crop system and alternative crop with rice systems at Cai Lay district - Tien Giang province. The study was based on a survey of 64 households in the Cai Lay district, Tien Giang province. Applying descriptive statistics, cost-benefit analysis were used to analyze the data. Comparing between two systems, income and profit of rice ? upland crop system is higher than two times rice monoculture system. Income of rice ? upland crop system is 86.8 million VND/ha and gross income of rice ? upland crop system is 57.5 million VND/ha. Income of rice monoculture system is 42.4 million VND/ha and gross income of rice monoculture system is 25 million VND/ha. Total cost is 23 million VND/ha for 3 rice crops/year system. Total cost average is 38.4 million VND/ha for rice ? upland crop system. Profit of rice ? upland crop system is influenced by factors: seed, pesticide and fertilizer cost. But profit of 3 rice crop system is influenced by factor: pesticide, labour, harvest cost. Base on the study results, rice ? upland crop system is considered effect about economy and income of the farmers. This is a system that is encouraged to improve farming systems of Cai Lay district. However, it is cared about cultural technique, market and upland crop variety.

Study have two parts: studying in characterization of fruit sap at harvest three times 7 a.m, 11 a.m, and 15 p.m, and cleaning stuck sap on skin by water, detergent, Ca(OH)2 and CaCO3. The results showed that the sap content exuded from peduncle of Chau Nghe mango fruit varied harvest time of day. Harvest in the morning had the most sap content (1,33 g sap/kg fruit), and the least in the evening (0,55 g sap/kg fruit). Sapburn on Chau Nghe mango skin was not significant (2-3%). Water, detergent, Ca(OH)2 and CaCO3 cleaned sap on skin completely, right after harvest fruit. Using water to clean sap stuck on skin after 48 hours was also good. The best time to clean fruit by water was not more than 24 hours after the sap stuck on the skin. The time of cleaning was in 10 minutes. All methods did not affect skin color, firmness, pH, and total solid solution of fruit.

Factors constituted household management capacity and their impacts on resource used efficiency are examined in this case study. In this research, firstly the method of in-depth interview with relevant specialists is explored to find factors constituting household management capacity, it is followed by household interview involving 178 samples randomly scattered in 3 agro-ecological zones with different corresponding farming system practiced to determine their management capacity levels. Results show that there are 8 factors forming household management capacity, in which the factors of household economic management and understanding market information are quite important in entirely household management. Most households surveyed have owned either a medium or upper medium level of management capacity, which implies that rarely number of household has own best management capacity. The management capacity positively effects household agricultural production?s profit. 

Thirty-two bacterial isolates capable of degrading 2,4-D were isolated from rice fields in Tien Giang and Soc Trang.

TG2, Cupriavidus sp. TG3, Cupriavidus sp. TG16, Ralstonia sp. TG26, and Burkholderia sp. TG27. In mineral salt medium supplemented with 2,4-D (500mg.l-1) as a sole carbon source, HPLC analysis indicated that Cupriavidus sp. TG2 was the most active 2,4-D degrader.

This paper focuses to analyse the metafrontier technique and metatechnology ratio, which are applied to solve the limitation of the data envelopment analysis (DEA) approach. The advantage of these methods is to allow the technical efficiencies of the farm households can be compared not only with those of households within a farming pattern but also with those of households from other patterns. In order to help readers easily reach these techniques, the empirical study has been conducted with the data on inputs and outputs of 55 and 46 households who followed the pattern of three-rice monoculture and rotational crops with two-rice and one peanut crop per year, respectively, in Cau Ke district, Tra Vinh province. The empirical results indicate that the households followed the pattern of three-rice monoculture are more technically efficient than those applied the other.  

The purpose of research was to determine the effects of the hydrological regime on soil properties within the Can Gio Mangrove Biosphere Reserve of Can Gio district, HCM city. This research addressed two questions: (1) What are topography and hydrological regime specific on the flooding frequency and (2) How does the hydrological regime affect on soil properties. Soil physical and chemical characteristics were measured at two sites, Khe Vinh (KV) and Mui O (MO) of the compartment 17 at three zones (1, 2 & 3) along three replicate transects at both two sites. Soil sampling was done in the topsoil at 10 cm and the subsoil at 30 cm. The sampling for most parameters was carried out in the dry season and repeated in the wet season. The result showed that the difference of elevation had different flooding frequencies. Overall, elevation and flooding frequency affected various soil properties. The soil texture at both the KV and MO sites was dominated by silt and clay, the subsoil had a higher sand proportion than the topsoil. Soil bulk density had a relationship with soil moisture with soil bulk density being higher during the dry season than the wet season. High pH was found at locations with high elevation and low flooding frequency. In contrast, low Eh was found at locations with low elevation and high water inundation. EC was highly affected by season and by elevation.

The article presents an online fuzzy tuning technique for a PI controller (proportional?integral controller) with wide enough tuning ranges around parameters obtained from Ziegler-Nichols tuning method. A hybrid control structure combining a PI controller and a fuzzy controller is established, where the PI controller plays a role of main controller to generate control signal and the fuzzy controller acts as a supervisor for real-time providing parameters of the PI controller. Experiments on Gunt-Hamburg RT010, RT020 and RT030 process control units indicate that the proposed controller is effective. System responses have suitable rising and settling times with negligible overshoots and zero steady-state errors. Besides, this controller also satisfies the requirements of real-time response and stability under condition of disturbances on the control system.
