Composting is the transformation of organic waste through decomposition by microbacteria into soil-like material. Organic waste used in composting is from agricultural waste like vegetables from farms, markets, restaurants, hotels, processing plants. There are two techniques of composting: (1) composting of waste pile with air supply system, (2) natural composting with air supplied by tossing the pile. Composting is used widely in other countries to manage waste. Composting not only results in a soil-like material as a good fertilizer but also it reduces a consiferable amount of waste.

Results of studying in 4 districts of Ninh Binh city in June 1998 showed that the morbidity rate in people over 60 year olds was highest, followed by groups of children under 1 year and 5 year. Female morbidity rate was higher than this in male, especially the women at ages of 16-59 (5.4% compared with 2.9%). The average frequency of incidence estimated 92 times/100 inhabitants/year (0.9 generally and 0.8 for male; 1.0 for female). The 3 common diseases were the central nervous syndromes, the chronic respiration diseases, and bone and joint pain.

The study was carried out on 48 workers producing polymer-composite material for over 2 years. The results showed that: although the exposure time is not so long, the polymer-composite material producing has influenced badly to workers' health such as: headache, fatigue... Workers have to be off more because of illness. There are functional changes of central nervous system such as: longer simple reaction time, impairment of short-term memory; decrease of concentration; decrease of electrical activeness of cerebral cortex and sleepy disorder.

120 healthy subjects were selected and divided into two groups to study the cutaneous conductivity at 12 couples of Yuan point, group 1 including 60 subjects aged between 21 to 25 (30 males, 30 females), group 2 including 60 subjects aged between 50 to 67 (30 males, 30 females). The results: there was no difference in cutaneous conductivity at 12 couple of Yuan point of the lest and right body in both groups of ages and sexes. In female, cutaneous conductivity at 12 couple of Yuan point were diferent depending on menstrual cycle, considerably lower in the latter haft of the cycle compared to the first half of the cycle. In the same age group, cutaneous conductivity at 12 couple of Yuan point in male was lower than that in female. In the same gender group, cutaneous conductivity at 12 couple of Yuan point of the group 1 was lower that of the group 2

Background: "Bach thuan" is a hereditary remedy which was written by herbalist Cao Van Tan, who was from Luu Ve, Quang Xuong, Thanh Hoa. The remedy has been treated effectively many diseases including the diseases related to infection wounds. Purposes: 1. to evaluate the antibacterial effect on Staphylococcus aureus and Pseudomonas aerucinosa in experimental burned animals. 2. to find unwanted effect of the "Bach thuan" remedy on experimental burned animals. Method: identifying the sensitivity of Staphylococcus aureus and Pseudomonas aerucinosa to the remedy. Conclusion: the remedy of “Bach thuan” had antibacterial effect to both Staphylococcus aureus and Pseudomonas aerucinosa. The remedy had effect of antimicrophyte to Staphylococcus aureus and Pseudomonas aerucinosa (ATCC 12228). With a dose of 25 mg/ml, the remedy killed 62.44% of bacteria after 4 days, 99.38% after 8 days of treatment. With a dose of 100 mg/ml, the remedy did not cause side effects

Study on the extract of Morinda citrifolia (MC) fruit with the ratio of 5:1 (1g extract was prepared from 5g of dried MC fruit) in order to determine the effects of extract on radiation-induced immunosuppressive mice. The results showed that: oral administration of this extract with daily dose of 6 g/kg in 9 consecutive days (3 days before and 6 days during receiving gamma ray) has increased the relative weight of spleen and thymus, total leukocyte count, number of lymphocytes, natural killers and monocytes, rate of immune rosette forming cells, hemolytic halo, and the skin test with OA antigen, compared with the mice group that has been only received gamma ray without drug

A random study on skin temperature change at 12 couples of Yuan point was carried out on 120 subjects. These subjects were divided into two groups: 60 subjects with duodenal ulcer and 60 healthy subjects served as control. Results: There were difference in skin temperature of bilateral Thai xung point in both male and female with gastric-duodenal ulcer (P<0.05-0.01). Temperature of 12 couples of Yuan point in this group was higher than those in control group (P<0.05-0.001)

In two years (1996 -1998) there were 55 patients with contracts and adherence of the scars in the axilla due to burn that had been operated in the department of plastic surgery of the national institute of burn with results: Good: 78,18%. - Medium: 21,82%. We have used surgery methods: transfer skin flap on the spot with Z,Y,V model, full thickness skin grafts or skin flap with vascular pedicle to cover defect after removed scars. But these methods must depend on the disposition, the position and the degree contracts of the scar. With these results, we affirmed that the effects of surgery methods in treatment for contracts and adherence of the scar in the axilla with a view giving back the movement function and the aesthetic for the those patients.

A study on the effects of Morinda citrifolia (MC) extract on the isolated blood vessels and water-electrolyte excretion by Lipschitz method. Results: MC in both concentrations of 1.25% and 2.5% had a vascular dilating effect of the rabbit ears without change vasoconstriction effect of adrenalin with concentration of 1/10 000. By oral administration, MC in doses of 0.3g, 0.6g and 0.9g/kg body weight increased the elimination of Na(+), K(+), Cl(-), but did not influence the elimination of Ca++ and urine amount at the rest time
