As a result of analysis on situations of environment-friendly school meals, it was obtained that student's parents were interested in food safety and the importance of sanitary supervision. Many parents responded that environment-friendly school meals increased the health and eating habits of their children. The higher and higher educated parents responded that environment-friendly school meals effected on the children's health positively. Also, the higher educated parents responded that environment-friendly school meals effected on the children's eating habits positively. After the environment-friendly school meals, the item increase to purchase was vegetables by 25% of the consumers who purchase environment-friendly agri-products. The second and third increasing items were respectively fruits and rice. When environment-friendly agri-products were consumpted and influenced positively through school meals, the consumption of environment-friendly agricultural products will be increased. The expansion of environment-friendly school lunch program cannot bring the consumption expansion of environment-friendly agri-products immediately. However, when the persistent promotion and student's parents confidence on environment-friendly agri-products were accumulated and experienced positive effects through school meals, it will give a positive effect on the consumption of environment-friendly agr-products.

We propose a method that combines learning in a virtual environment and a real environment for indoor autonomous driving through reinforcement learning. In case of learning only in the real environment, it takes about 80 hours, but in case of learning in both the real and virtual environments, it takes 40 hours. There is an advantage in that it is possible to obtain optimized parameters through various experiments through fast learning while learning in a virtual environment and a real environment in parallel. After configuring a virtual environment using indoor hallway images, prior learning was carried out on the desktop, and learning in the real environment was conducted by connecting various sensors based on Jetson Xavier. In addition, in order to solve the accuracy problem according to the repeated texture of the indoor corridor environment, it was possible to determine the corridor wall object and increase the accuracy by learning the feature point detection that emphasizes the lower line of the corridor wall. As the learning progresses, the experimental vehicle drives based on the center of the corridor in an indoor corridor environment and moves through an average of 70 steering commands.

Landsat images were globally used to monitoring the Earth's. But it is not positively applied to a field of environment such as coastal environment, heat island effect and drought condition and so on. Until recently, Information about a ecology natural environment came to do by direct investigation. But Information about a ecology·natural environment of wide area were quickly getting possible with the progress of remote sensing technique. Specially, the up-to-date characteristic information about an ecology·natural environment as the basic intelligence for a country development activity are very important. So, it applies the satellite images that the periodic observation of data is possible. In this study, We planned the function which is possible helping the renewal of an ecology·natural environmental information using Landsat imagery. Also planned the DB suitable for these purpose. For application of thermal infrared band images we developed the function that extracts an isothermal line. It used the thermal infrared band images and it grasped a temperature distribution. The result is useful in analysis of the city heat island effectiveness.

The purpose of this study is to find out eco-friendly attitude and level of knowledge about environment of pre-service elementary teachers and find relationship between these. In this study, we investigate and analyse with surveys about eco-friendly attitudes and environmental knowledge questionnaire targeting the 2nd semester of 2013 32 people of fast stream class 2nd grade. Also, we analyzed correlation between environmental knowledge and the test results of eco-friendly attitudes. Results for the analysis are as follows. First, pre-service elementary teachers' average of eco-friendly attitudes test result is 'cognitive area(60.22)> definitional area(53.69)> behavioral area(52.72)'. These results are re-service elementary teachers are knowledgeable about the environment, but they are passive at the execution act about environment. Second, the average of pre-service elementary teachers' environmental knowledge result is the highest to the protect the environment, for the average(26.25). It is interpreted that they acquired the most the knowledge related to the conservation of the environment. Third, It is no significant correlation between pre-service elementary teachers' eco-friendly attitudes and environmental knowledge. It means that although they acquired a lot of knowledge related to the environment, it is not affected to environmental friendly attitude putting ideas into action about environment.

The activation of consumption of environment-friendly agricultural processed foods means not only the growth of environment-friendly agriculture, but also the development of related industries. Therefore, it is necessary to identify and apply the needs and purchasing attributes of environment-friendly agricultural processed food consumers. For this, survey was conducted to adult men and women in their 20s and 60s and a total of 200 copies were used for empirical analysis. In this study, the average difference between importance-satisfaction for purchase attributes of environment-friendly agricultural processed food was verified, and the IPA Matrix was prepared based on this. As a result, in terms of purchasing importance and satisfaction, it was found that those with no experience in purchasing environment-friendly agricultural processed foods regarded product, price, place, promotion as more important than those with experience in purchasing. In case of IPA, product and price factors were all important and satisfactory regardless of purchasing experience. On the other hand, it was found that the key factors for promotion were neither important nor satisfied with consumers regardless of their purchasing experience. Therefore, it is mainly necessary to focus on marketing and mass media promotion. At the same time, various domestic and foreign best practices should be benchmarked and a 4P marketing strategy should be established and promoted.
