The present study investigates the effects of English task-based learning on highschool English education. To accomplish these the tasks for the high school students were designed and introduced in to their regular classes. The students were classified into two groups(the experimental and the control) out of 6 classes in'0' High School in Seoul. The experimental group dealt with the tasks every class, while the control group learned English according to the teacher-led teaching. These processes were applied for a total of two fifty minute classes per week for six weeks. The following hypotheses were tested as follows: Firstly, the task-based learning group(the experimental group) will be more effective than the no task based learning group(the control group) on the test. Secondly, the task-based learning group will be more effective than the no-task-based learning group on the degrees of interest. Thirdly, the task-based learning group will be more effective then the no task-based learning group on the degree of confidence. Finally, the task-based learning group will be more effective than the no task-based teaming group on the degree of self-direction. For the analysis, tests and questionnaires were administered. The results are summarized as follows: Firstly, the test scores in the experimental group(the task-based learning group) showed more significant improvement than in the control group. Secondly, the degree of interest in the experimental group showed more significant improvement than in the control group. Thirdly, the degree of confidence in the experimental group showed rare significant improvement than in the control group. Finally, the degree of self-direction in the experimental group showed more significant improvement than in the control group. In conclusion, the findings in this study suggest that the task-based learning in highschool English education are effective and meaningful to develop the students' English abilities. The English teaching based on task-based learning method will put learners into situations where they use English for the purpose of react communication. For the future study, it is necessary that the variable tasks should be designed and allied in the classroom to prove the positive effects on communicative competence. Also, the improvement of educational environment and the evaluation system should be introduced to the task-based learning. Finally, it is important that the teacher is for the students to improve their English abilities and their task-based learning abilities.

Objectives: The purpose of this study was to evaluate the personal exposure to $PM_{10}$ by body parts for the development of dust monitoring wearable device for swine farmers. Methods: Tasks were classified by using motion pictures taken by action cameras attached to swine farmers. Concentrations of $PM_{10}$ were measured by attaching direct-reading instruments at the head, neck and waist of worker. Differences of $PM_{10}$ exposure between body parts were analyzed with linear regression. Results: We identified three tasks(vaccination, moving pigs, and manure treatment). $PM_{10}$ concentration during vaccination was the highest among the tasks, and the body part showing the highest concentration of $PM_{10}$ was the waist regardless of task. In all tasks, the closer distance between the body parts, the higher were the R-squared values(vaccination 0.4221, moving pigs 0.6990, and manure treatment 0.2164). Conclusions: We presumed that $PM_{10}$ concentrations were affected by the parts of the body in which they were measured. In order to develop swine farmer's wearable device for monitoring dust concentration in air, the determination of the positions of monitoring sensor to ensure accurate measurement is essential. Considering the results of this study, wearable sensor should be positioned at the waist.
