Abstract

This study was aimed to investigate the comparison of the work environment and the health problems of woven nets worker among formal workers and informal workers in Nong-rua district, Khon Kaen Province. The data will be collected by interviewing from the sample group : 134 workers which are the formal woven nets workers and the informal woven nets workers who works in the net fishing process for more than a year, using the survey to investigate the environment in workplaces and measuring the volume level and light intensity in 24 workplaces at the factory and 59 residences. This study was analyzed by the descriptive statistics such as frequency, percentage, mean, standard deviation and inferential statistics, used the multiple logistic regression for the correlation analysis. The data were presented by Odds ratio and 95% of confident interval.

The results from 54 persons in formal woven nets workers and 80 persons from informal woven nets workers were showed that the formal woven workers work 12 hours a day, informal woven nets workers work 9-12 hours a day and the highest is 15 hours a day. In the environment at workplace survey section, the results are the light intensity was between 340-1600 lux (from the standard ≥ 300 lux) the volume level was between 76.2-83.6 dBA (TWA 12 hrs ≤ 87 dBA). The light intensity in the workplace is lower than the standard for 35.60% because of there are no lights setting up in the machines and turn on light while working is not allowed. The volume level is between 60.9-74.8 dBA. Most of the injured that was found during the year of this study is workers got a wrist ache. Woven nets workers got injured while working: 42.59% of the injured form scissors were happened with formal workers and the roadblocks at workplace caused the injured from fallen to 57.25% of informal workers. The comparison of health problem in among two groups of workers followed by the average of violence from injured showed that workers who have a ringing in oneûs are different from the worker who have a muscle pain in the statistical significance at 0.05

The factors which relate to the health problem in formal woven workers is worker who has been working for more than 5 years is risk to have an injured to 2.89 times of the worker who works less than 5 years (95%CI=1.87- 3.89). At the workplace where the light intensity is lower than the standard is risk to get the blurred vision to 1.69 time of operations that has light within the standard (95%CI = 0.40-2.49) The informal woven nets worker that have never been working inside the factory have a chance to get the accidents form working to 2.42 times of worker who work inside the factory (95%CI = 1.62-4.92). The area of operation of the disorder is likely accidents 1.98 times of the disorder (95%. CI = 1.39-3.92) which the statistical significance is 0.05.
