The results suggest that Self-Esteem variable is not related to the PWB, since the association between these two variables is negative, although not significant (r = -.090). The results also show that there are no significant differences between students of Sport and Psychology in the levels of BEP and its dimensions. Nevertheless, it is clear that when put together, the knowledge in the areas of Psychology and Sport, are able to increase the PWB. In conclusion, the knowledge in the mental health area and physical activity establishing itself areas to invest to promote overall mental health levels.

The main results show that elevated levels of general Perfectionism and general Self-concept, as moderate levels of general Aggressiveness, characterize the overall profile of the young military. The comparative gender analysis showed that there are significant differences in the results regarding levels of aggression only.

Abstract
The exponential growth of mobile usage in developing countries, the tendencies between the usage of Apps and Responsive Websites, the characteristics as well as advantages and disadvantages between the two, urge this study to be conducted. This study aims to compare the effectiveness, the efficiency, and satisfaction (usability) between different mobile solution: the Apps and the Responsive Website. User-Centered Design Methodology was used in this study with an example of street food in Phnom Penh, the capital city of Cambodia. Some of the ethnographic methods are field observation, semi-structured interviews, and the creation of personas. These methods collect information to determine motivations and needs of the user. A mobile solution which will be created and evaluated as a prototype in its different stages of development is also proposed. It will also take into consideration the connection between social network sites and the platform because Facebook has lately become the second most important source of information after television in Cambodia. Eventually, a suggested prototype for this sort of street food in a developing country will be proposed as well as a robust framework comparing this prototype as Mobile Application and Mobile Responsive website platforms.
