This paper designs an application for detecting various objects using a smart phone with camera sensor, then implements the application that detects the number of faces in front of a user by using the Face API provided by android and generates a speech to the user. For implementing the application, the GoF strategy pattern is applied to design the application. It provides some advantages; first, the algorithm development schedule can separate the whole application development schedule; next, it makes easier to add the algorithm. For example, another detecting algorithm for the other objects (character, motion detection) that may be developed in the future, or it may be replaced by a more high-performance algorithm. With the propose method, a general smart phone can make some advantages that can provide information of various objects (such as moving people and objects, and detected character from signboards) to the person who is visually impaired.

Web application security education that can provide practical experience is needed to reduce damage caused by the recent increase in web application vulnerabilities and to strengthen security. In this paper, we proposed a scenario-based web application education method, applied the proposed method to classes, and analyzed the results. In order to increase the effectiveness of scenario-based education, a real-life practice environment to perform scenarios and instructions to be performed by learners are needed. As an example of the proposed method, instructions to be performed by learners from the viewpoint of the attacker and the victim were shown in a practice environment to teach XSS and SQL injection vulnerabilities. After applying the proposed method to the class for students majoring in cyber security, when the lecture evaluation results were analyzed, it was shown that the learner's interest, understanding, and major ability all improved.

This paper deals with the problem of estimating regression coefficients in nonlinear regression model having random regressor. The sufficient conditions for consistency of the $L_1$-estimator with random regressor are given and discussed in this paper. An example is given to illustrate the application of the main results.

This paper proves that a filter for scramble spectrum is realized by a periodically time-varying digital filter. Further, we propose a design method of this filter by using a bi-frequency map. As an example, we implemented this filter with Digital Signal Processor.

Load Variation effects on the system driving performance. Therefore, this paper presents as a application example of Anti-windup method using general incremental form for a gun servo system of load variation involved. Also, this method can be easily implemented compared to gain scheduling technique.

Pneumatic equipments are widely used in factory automation. Compressed air has many merits, but because of compressibility pneumatic actuators are used limitedly where requires an exact intermediate stopping positions and very slow constant speed. This paper shows the application example of multi-position cylinder to the forming machine.

As a typical example of the screening for a microbial biocatalyst from nature, isolation of nitrilesynthesizing microorganisms, characterization of a new enzyme aldoxime dehydratase, and its function in the aldoxime-nitrile pathway are introduced. Catalytic properties of some of our enzymes were improved through a direct evolutionary approach.
