Objectives: A field survey was conducted in a hog-raising industry in order to help develop personal protective equipment for workers which would secure the safety and the health of these workers. The attempt by this study will help enhance safety in the livestock industry and contribute to the advancement of the industry. Method: The study first selected a total of 111 workers from the hog-raising industry as research participants and designed a survey with questions on general characteristics, indoor and outdoor working environments, how the workers would in practice wear or purchase the working clothes, what needs to be improved in these new working clothes, how much the workers would be likely to accept the working clothes and protective equipment, and lastly, conditions of the communicable disease control overgarment. The collected data underwent frequency analysis and cross analysis with SPSS 21.0. Result: The research targets' average age was 50 years. Work efficiency by environmental factor was normal, but all age groups had experience of accidents (79.3%). Major wounded parts were under elbow and under knee. Protective equipment most commonly worn was helmet (83.4%), gloves (98.2%) and boots (99.1%), and satisfaction with them was normal at 3.41. Working clothing most commonly worn was old clothing (31.8%) and everyday wear (17.6%) and satisfaction with it was low. Considering the improvement of working clothing, they required attached pouches, elasticity and deodorization. The acceptability of improved working clothing was high at 69.2%. Conclusion: After problems have been addressed in relevant future research, what has been learned from the concerned study will be referred to as a useful basic reference when the relevant field works to develop high-quality working clothing and protective equipment for workers in the hog-raising industry.

This paper is concerned with the development of a simple digital stethoscope system for diagnosis of cardiac disorders. This system consists of an electronic stethoscope, IC sound recorder and a notebook computer. The cardiac sound is easily acquired by the electronic stethoscope and then recorded in IC memory stick so that the digital cardiac signal can be simply transmitted to the computer for signal display, disease diagnosis, and personal history record. A software is built with functions displaying the sound graphically and replaying the sound clearly. Further, a neural network recognition system for automatic diagnosis of cardiac disorders is also added to the software.

This paper examines the casual relations among service quality, perceived value and satisfaction from the perspective of Job Fair attendees. Numerous studies have been conducted in the field of perceived value and satisfaction. This work would be the mere contribution in the literature development but surely contribute to the better development of service providing sector to create better quality, value and satisfaction. A framework suggested that personal service, touristic attractiveness and physical environments were turned out to affect positively on the perceived value and satisfaction. The service providers should concentrate on developing the issues.

This paper explores how unequally successful mathematics practices were constructed in the two elementary mathematics classrooms. The interview data that pertain to the two teachers' personal reflections on the influences on their professional development were used as a source of inquiry to identify the underlying factors that might account for the differences and the similarities in implementing reform ideals in teaching mathematics. This affords not only exploration of the challenges of moving teaching practices toward student-centered approaches but also insight of the processes of developing mathematics teaching practices through teachers\`own career paths.

Improve of productivity is a key for the development of a company, which can be pursued in the apect of material factor and personal factor. And the motives of worker for their job is more influenced by the chance of incentive compensation or self-development than by participation in management and safety of their post ect. Contingency theory is one of the theories that cope with this study Therfore, this study describes incentive compensation for satisfying worker desire related company's productivity, and be presented to the aspect of contingency accounting.

Objectives: Time location data are critical for accurately estimating personal exposures. This review papers summarized various measurement methods of time location pattern for air pollution exposure assessment. Methods: Forty manuscripts (papers, books and reports) were reviewed to comprehensively describe time location measurement methods. Results: This review included traditional methods such as time activity diary, questionnaire, observation, focus group and newly developed technical methods including global positioning system, web, radio frequency identification and ultrasound detection. Some research applied a combination of methods. Conclusion: Although various methods have been used to collect time location data, further development of accurate measurement methods for time location data is needed.
