Android applications are inherently vulnerable to a repackaging attack such that malicious codes are easily inserted into an application and then resigned by the attacker. These days, it occurs often that such private or individual information is leaked. In principle, all Android applications are composed of user defined methods and APIs. As well as accessing to resources on platform, APIs play a role as a practical functional feature, and user defined methods play a role as a feature by using APIs. In this paper we propose a scheme to analyze sensitive APIs mostly used in malicious applications in terms of how malicious applications operate and which API they use. Based on the characteristics of target APIs, we accumulate the knowledge on such APIs using a machine learning scheme based on Naive Bayes algorithm. Resulting from the learned results, we are able to provide fine-grained numeric score on the degree of vulnerabilities of mobile applications. In doing so, we expect the proposed scheme will help mobile application developers identify the security level of applications in advance.

This study has been conducted on 213 students in 4-year universities located in the regions of Daejeon and Chungnam in order to investigate a method to develop a smart device based culinary education application and the results and development method were as follows. First, the most often used smart device was a smart phone, which is used for over 5 hours a day and mainly used for SNS. Second, they utilized a smart device for language and major study during their spare time, wanted educational contents most and thought them useful for learning. Third, most of the students were positively aware of the necessity and learning effects of culinary education applications, and the response rate to utilize the application once a week was highest. Also, they hoped various recipes and simple cuisine and craftsman cooking. Therefore, the functions of SNS mostly often used by students should be added to promote interaction between teachers and students. And more contents should be made for students to use easily in moving or in their spare time. Furthermore, various videos of teaching and theoretical information should be included. And the applications focused on recipes and simple and craftsman cooking should be developed and uploaded on a school homepage and on popular portal sites so that students can easily utilize them.

Existing attending management systems require a high cost and are lack of convenience. In this paper, we propose a convenient and practical attending management system as follows: First, our system allows us to construct an attendance book in an easy and simple way. A professor does not have to provide the information of students using the small screen of his smartphone. Instead, each student manages his own information via the app designed for a student in our system. Then the professor can construct the attendance book using another app designed for the professor by confirming the requests from the app designed for a student. Second, our system enables a professor to utilize the pictures of students as well as other information of students to have a good relationship with students. Third, our system provides a functionality of checking attendance automatically by calling the names of students via the app designed for the professor. Then the professor has only to match the name with the face of each student. Fourth, our system provides a functionality of checking attendance in a very fast manner. Our system can complete this behavior within a short time since all students can join the attendance simultaneously by using the app designed for the student. Fifth, our system can prevent an illegal attendance easily by utilizing the distance information.
