en: Player tracking has become a crucial technique for getting strategic advantage in competitive team sports. Movies captured by one or a few cameras are easy to use for this purpose at any level including amateur. This study describes a design issue that integrates up-to-date technologies of multi-object tracking for tactics detection from the actual game data to bring affordability, feasibility, and accessibility.

en: An webserver should be maintained by its experienced administrator under the firm knowledge and conviction on vulnerability measures. General administrators of novice learn the vulnerabilities with public literatures to get knowledge while unlearnt people sometimes try by the Internet articles for its affordability. However, the configuration of vulnerability countermeasures can be represented structurally. Therefore, even novices should learn more efficiently by using a learning support system originally developed those structures with the elements of vulnerability countermeasures than by learning with the literature. The system asks questions based on the learner's understanding. In the experiment, learners were divided into two groups of studying by the literature and studying by the system. Through the experiment consisted of a pre-test, learning, and post-test, the average score indicates the advantage of the system while the literature-based study shows partially advantageous. The explanatory text and feedback for items that the learners could not answer correctly need to be revised.

en: Modern information communications use cryptography to keep the contents of communications confidential. RSA (RivestShamirAdleman) cryptography and elliptic curve cryptography, which are public-key cryptosystems, are widely used cryptographic schemes. However, it is known that these cryptographic schemes can be deciphered in a very short time by Shors algorithm when a quantum computer is put into practical use. Therefore, several methods have been proposed for quantum computer-resistant cryptosystems that cannot be cracked even by a quantum computer. A simple implementation of LWE-based lattice cryptography based on the LWE (Learning With Errors) problem requires a key length of O(n2) to ensure the same level of security as existing public-key cryptography schemes such as RSA and elliptic curve cryptography. In this paper, we attacked the Ring-LWE (RLWE) scheme, which can be implemented with a short key length, with a modified LLL (Lenstra-Lenstra-Lova sz) basis reduction algorithm and investigated the trend in the degree of field extension required to generate a secure and small key. Results showed that the lattice-based cryptography may be strengthened by employing Cullen or Mersenne prime numbers as the degree of field extension.
