| Summary: | 碩士 === 中華醫事科技大學 === 職業安全衛生系暨碩士班 === 107 === In recent years, environmental health has become more and more important, and the cleaning industry has flourished. The cleaning industry service has provided professional and high-quality service with the introduction of corporate management concepts. However, most of the cleaning personnel are middle and high age groups, and their work is repetitive. Heavy-strength and unnatural posture types are prone to musculoskeletal discomfort, so the clean industry is a high-risk group of musculoskeletal discomfort, and the proportion of musculoskeletal discomfort in domestic occupational disease notification cases has increased in recent years. This phenomenon not only causes labor to be unable to work due to musculoskeletal discomfort or affects work efficiency, but also causes productivity to decrease and social costs to increase. Therefore, this study explores the health hazards and causes of musculoskeletal discomfort in cleaning personnel and seeks ways to improve.
This study is aimed at the basic medical information and discomfort investigation of the employees of a company cleaning company. The content structure of the questionnaire includes: (1) basic personal data , (2) whether it has caused injury due to work, (3) investigation of symptoms in various parts, (4) other, parts of skeletal muscle discomfort Explore it. The NMQ Nordic Skeletal Muscle Injury Questionnaire was used to find out the correlation between the symptoms of skeletal muscle discomfort in the cleansing staff and to investigate the conscious discomfort. And propose improved tools and design workflow for follow-up. The questionnaire was based on a paper questionnaire. The subjects were divided into an experimental group (with 19 use improvement tools) and a control group (23 without improvement tools), and the same questionnaire was administered to the same group three months later. A total of 42 employees and 84 questionnaires. The recovery questionnaire will collect the data separately. After the database is established, it will be imported into the statistical analysis software SPSS 21.0. The data analysis method uses descriptive statistics to understand the distribution of each disguised state of the subject. Inferential statistics were analyzed by Chi-Square to examine the differences and correlations between skeletal muscle injury symptoms and variables.
The sample of this study averaged 50.4 years old and had a 6.03 qualification in cleaning work. The average height was 171.1 cm and the average weight was 73.85 kg. There were 26 people who felt unwell because of work relationship. Labor musculoskeletal injury, according to the neck, left shoulder, left elbow, left wrist, left thigh, left knee, left ankle, upper back, lower back, right shoulder, right elbow, right wrist, right thigh, right knee, right ankle, etc. The chi-square test for the influence of "whether it feels musculoskeletal discomfort" shows 8 variables such as neck, upper back, lower back, right shoulder, right elbow, right wrist, right thigh, right knee and whether or not to feel musculoskeletal discomfort. Related. According to the improved cleansing personnel, according to the post-improvement discomfort questionnaire, the number of significant items in the chi-square test was found to be significantly improved, and the degree of discomfort was also significantly reduced, which proved that the replacement of the working tools can significantly improve the musculoskeletal injuries of the employees.
This study explores whether employees' skeletal muscles are harmed and their severity, and tools to improve the level of employee bone damage. Most of the cleaning staff are middle and high age groups. The high repeatability of work is easy to cause discomfort to the musculoskeletal, and the age and the musculoskeletal injury gradually appear. Therefore, the prevention of musculoskeletal injuries is more important. For such questions, here are the suggestions:
1. Provide more cleaning machines for employees, such as sweeping cars, mopping cars, waxing cars, etc.
2. Have systematic planning of labor work. Don't always do the same work by the same person. It will be changed once in a while. For example, the person who was responsible for cleaning the floor will exchange with the person who cleans the glass after a period of time. Wear of the same part.
