1.Real state of working load of vapor iron worker in Duc Giang Garment Factory, Gia Lam district, Ha Noi
Journal of Practical Medicine 2003;439(1):36-39
89 male workers of vapor iron were subjected to the study. The investigation of labor evironment and worker conditions showed that: indoor temperature exceeds that of hygiene standard by 0,2-1,0oC, humidity and wind velocity is tense (2080 movement for each shift) working movement duration is short (12 second for each movement), in the shift, breaking time is insufficient to meet the need of rest. After a working day, memory, the attention, the tonus of muscle decrease dramatically in comparing with those before the shift the decrease is significant statistically. Many sites of pain occur considerably and concentrate in the nape, right arm, back, thigh and knee

2.Working environment and the worker health status in 8/3 textile company
Journal of Practical Medicine 2003;442(2):32-35
Working environment and worker’s health status of 2432 subjects of the factories of thread, of wearing, dying, the factory of perfectioning and garment belonging 8/3 textile company. Results showed that in most of studies places, the permissible criteria were reached, excluding some harmful factors such as temperature, wind speed, light, noise, dust concentration, nocious gas. In more than 50% of total number of workers were of 1st and 2nd grade of health, and it’s better in the male than in female subjects. The diseases of high incidence are respiratory diseases, gynecological diseases and nervous diseases and their different rates depend on the working characteristics, increasing progressively with working age

3.The influence of working environment on the health of workers at Binh Dinh construction factory
Journal of Practical Medicine 2003;439(1):67-69
The working environment of 138 workers at Binh Dinh construction factory was studied concerning the harmful factors determined by the Institute of Occupational Medicine and Working environment. Almost harmful factors are highest then allowed standard, especially total dust (>3,7 times), high SiO2 content level 24-42%. In almost studied field, the noise density is higher than standard (90 dBA). There is a high incidence of some diseases such as stomato-dental diseases (50,27%), ENT and respiratory diseases (37,14%). Occupational safety and health care for workers were neziligible; commonly available masks for respiration are not proper for filtering the dust

4.Silico-pneumoconiosis in workers of the factory of paved stone and construction in Binh Dinh Province
Journal of Practical Medicine 2003;442(2):20-22
Studying on clinical symptoms and respiratory function of 83 workers above 5 years professional age (86% male and 14% female) showed that there are predominantly 2 functional symptoms: chest pain and dipnoea, then sputum, cough and hemoptisis, two physical symptoms of deformity of the chest, vesicular murmur, were of higher rate. The incidence of respiratory total dysfunction accounts for 38.6% in workers. The incidence of silico-pneumoconiosis is 9.6%, mild form is common in most of workers

5.Health status and hearing of the workers who have been exposured to organic solvent at Phóc Yªn and Yªn Viªn shoe companies
Journal of Vietnamese Medicine 2001;267(12):83-85
The studies involved 192 workers exposured to organic solvent and have worked at least 4 years or more. Overall, in both companies, 45.6 - 46.8% of participated workers have category III of health status, 8.5-13.9% have category II and 2.53 - 4.26% have category I. The incidence of otorhinolaryngological and dentistry diseases is highest. RBC, hematocrite and platelet counts tend to decrease in comparison with general population. Mean urinary hypuric acid level in exposured workers is higher than in others. Overall, in both companies, 14.4% of workers have some degree hearing loss.

Background: Can Gio mangrove forest is bio-diversified area. There is few studies on medical arthropod in Can Gio mangrove forest until now. Objective: To study bio-diversified feature and identify species with disease transmitting role. Subject and Method: In 2007, medical arthropod surveys were conducted at 3 sites located in the natural conserve zone- Can Gio mangrove forest. A cross-sectional study was used. Results and Conclusions: A total of samples of 6178 individuals of medical arthropod belonging to 65 species have been collected, including 3 species of flea (Siphonaptera), 1 species of ticks (Ixodidae), 6 species of chiggers (Trombiculidae), 6 species of mites (Gamasoidea), 25 species of flies (Muscoidea) and 24 species of mosquitoes (Culicidae). They belong to 37 genus, 17 families, 3 orders (Siphonaptera, Acarina and Diptera), and 2 classes (Insecta and Arachnida). 20 species having epidemiological role were found in Can Gio mangrove forest. The rate of Anopheles epiroticus biting human at night indoor, outdoor and daytime indoor is rather high, especially at the end of dry season at centre of the forest.

Background: In the period 2006-2010, a investigation on medical arthropod has been conducted\r\n', u'Objective: 1) To determine species composition and distribution of medical arthropod. 2) To find species transmitted disease \r\n', u'Subject and method: The cross sectional, descriptive and analytic investigation was conducted in 3 communes along the Ho Chi Minh road in Cao Bang province. \r\n', u'Results and conclusion: : A total of 3.437 of samples of medical arthropod belonging to 96 species have been collected including: three species of flea (Siphonaptera), two species of tick (Ixodoidea), four species of chigges (Trombiculidae), ten species of mites (Gamasoidea), twenty four species of flies (Muscoidea), and fifty-three species of mosquito (Culicidae). They belong to 39 genuses, 17 families, 3 orders: (Siphonaptera, Acarina and Diptera); two classes (Insecta and Arachnida). \r\n', u'Some species having epidemiological role such as Aedes albopictus, Culex tritaeniorhyncus, Cx. quinquefasciatus, Cx. vishnui ... were predominant at all study sites. Anopheles minimus, the main malaria vector, was mainly collected in cattle- sheds in Truong Ha and Bach Dang communes. \r\n', u'
