Recently, telematics devices have been used for driver’s safety and convenience .Telematics market including navigation is getting bigger and bigger. However, traffic accident from using telematics equipment is also increasing. Drivers may lose glance using navigation, and driver’s workload will also grow by driver’s distraction. This thesis is base on the study about the influence on the driver’s workload according to combination of display by DOE(design of experiment). The main object of this thesis is measuring the workload according to the telematics usage by HMI (Human Machine Interface) in the virtual reality. The result of these experiments is that workload when driver used navigation was different with a style of text type. Also, it confirmed the significant result from the statistics analysis.

Driver obtain an information by the visual over the 90% and provide an information by road sign. However the road sign system of highway has a driver's discomfort and traffic accidents by some possibility. Experiment of reality highway has a demerit that increased the traffic accidents and difficult to obtain the accurate an experiment result.Subsequently, this paper had an experiment for evaluation of highway driving safety for reduce the accidents factors to a highway design and developed the highway database was classed as original design and alternative design. Design of highway database was developed exactly like real highway and operated an experiment by driving simulator. Highway database was constructed compatible with DirectX by Multigen program. Four types of physiological (electrocardiogram, electromyography, electrooclulography, galvanic skin response) measurement was acted for 33 subjects using the Biopac equipment in the developed highway database. Also, analysis of driver's state was acted using a SWAT(Subjective Workload Analysis Technique), NASA-TLX(NASA-Task Load Index), MCH(Modified Cooper-Harper) among the psychological methods. Statistic analysis was operated for assure the result data reliability using the SPSS(Statistical Package for the Social Sciences) 12.0 program.

In this paper, we study how the physical environment (temperature, humidity) during the distribution of farm products effect the quality and shelf life of farm products. Subsequently, we monitor the distribution environment of farm products with sensor network. Then, based on the monitoring results, we predict the quality of farm products. Finally, we analyze how the distribution & store environment effects the quality of farm products. Also, through the analysis we study a predication method for the quality of farm products based on the monitoring results of sensor network. As the results for apples, we can obtain the shelf life limitations period, weight reduction rate, and prediction equation based on the quality factors-temperature, humidity. As the experimental results, we can obtain the merchantability and optimal distribution time for agro-foods.

In this paper, we present that it is about the monitoring system for disaster prevention using an antiseptic water production device and a car license plate recognition system. The antiseptic water production devices consist of a storage, spray, connection part, and an antiseptic water unit. The car license plate recognition systems consist of an automatic recognition system for cars and license plate recognition system. Using the above described components, we could implement the monitoring system for disaster prevention that consist of realtime monitoring, objects, configuration, user, login/out management part. As the results, we could prove the function of disinfection for an antiseptic water and monitor the information about cars to be used for disinfection. Simultaneously we could get the information about cars and drivers. Also, using the functionality of implemented systems integration management, we could obtain usability and efficiency in agriculture to be characteristics.
