In recent years, there has been an increase in the number of people suffering from bone related health issues. This can be attributed to our sedentary lifestyle, which allows us to go for days without getting adequate sunlight. Exposure to sunlight, or UV radiation is often associated with negative images of skin cancer and sun buns; however, adequate UV exposure is important in creating vitamin D, which plays a key role in maintaining the levels of calcium in our bodies. While many studies point out the benefits of exposure to sunlight, existing researches dealing with behavior change tries to promote sun protection behaviors or tries to prevent people from exposing themselves to UV radiation. This poses an alternate threat of bone related health issues towards those who are not getting enough sunlight. In order to motivate people to continue to get adequate sunlight exposure, we will create an application that provides interventions geared toward one's personality, as well as using context aware notifications to allow for behavior change. This system will employ the use of the OCEAN Model to determine the personality types of the users and will attempt to persuade the user to change their behavior with UIs that are designed specifically for those personality types.

Road maintenance requires local city governments to dedicate a substantial amount of funds in finding and repairing damaged traffic marks and pavements. In developed cities, the total road length is so large that the cost becomes unreasonably high. In this paper, we propose a method of sensing damaged traffic marks from images captured by a camera mounted to a car, for the purpose of reducing road maintenance cost. In particular, we utilized convolutional neural networks (CNN), as well as linear support vector machines (SVM) and Random Forest, in developing a system of damage detection. The experiments used thousands of images captured in the wild and showed that the method can detect damages using CNN with 93% accuracy, at maximum, and at reasonable speed (55 images per second).
