It has drawn a great attention as anew problem yet to be solved that "low completion rate" is the teething problem of e-learning ever since it was introduced into education. In this research, we have verified the hypothesis that the cause of the low completion rate is derived from the possibility of learners who are not suitable for e-learning because the learning effect of e-learning varies depending on the learning type of the learner. Our verification revealed that the task fulfillment rate of e-learning varies according to the learning type which is divided into seven categories. This result suggests that e-learning can produce almost no learning effect when the learning type of a learner does not match e-learning.

The explosive popularization of mobile devices such as smartphones has greatly changed the information environment of young people. On the Internet, various kinds of information are provided, and at the same time, there are many socially undesirable information. Even information that is considered socially undesirable, if you are an adult, you should judge the value yourself without limiting that information. That is the idea of “freedom of Expression ”(the right of the people to know). However, for young people in the middle of growth, there is a risk (Content Risk) involved in unexpected troubles by contact with these harmful information. In addition, risks (Contact Risk) caused by using “Dating Sites and SNS, as well as “CyberBullying” at the “Underground Portal Weblog Sites by School-Children”, have become a problem particularly in society recently. Furthermore, there are risks of privacy protection and information security on the Internet, and some systems to protect young people more than adults are necessary. How to protect young people from the risks related to these information behaviors is an important social issue. In this paper, we will examine the present situation of risks concerning information behavior of young people and the effectiveness and problems of some systems concerning youth protection.

While the opportunities to handle digital data are rapidly increasing, it is necessary to consider how to realize the copyright protection of digital contents. Digital watermarks are attracting attention as one of copyright protection technologies for digital contents. Digital watermarking is a technique that uses human perceptual characteristics for digital contents, and embeds information that is different from the content itself, which cannot be recognized by human perception. In previous research, there is a digital watermarking method for image information using the concept of spectrum spreading, and a user ID encoding method with resistance to collusion attack is proposed under the method. In this proposed method, resistance to images against various attacks is evaluated, and the detection capability of user identification information is clarified. We adopt StirMark as an image processing attack tool against digital watermarking and investigate its usefulness.

Recently, a human attribution detection by face recognitionreceives attention from many application, such as age and gender detection in digital signage. However, the face recognition has many problems, and one of them is a partial disappearance of face that is so called occlusion. Since the facial information is lost by disappering a partial region in the face, attrubution classification and face detection become difficult under occlusion. As handling method for occlusion in attribution classification, the method using only a partial region of face is proposed. In recent study, periocular region, which means the rectangle region including eye and brow, receives attention in terms of high classification accuracy when it is used as input. Therefor, we performed the periocular region detection method with a partial face region detection and then compared feature representations in periocular region. We propose this method for the purpose of increasing human attribution classification accuracy. In periocular region detection, both eye region detection is used instead of whole face region detection. In addition, both left and right regions are re-searched after the input image is rotated with an adequate angle, when the both eye regions are not detected.

Let a, b and c be relatively prime positive integers such that a + b = c. We have been conjectured that L(c) is less than 2L(rad(abc)), where L is the logarithmic function derived from Euler function and rad(n) is the radical of n. So far, it had been verified that the conjecture is true for c < 10^5, using computer resources. In this paper, we propose a fast algorithm for enumerating abc-triples such that L(c) ≥ (1+ε) L(rad(abc)). Using this algorithm, we also verified that the conjecture holds for c < 2^30.

When trying to interpret tanka or short poems from a cryptographic point of view, many are done from the viewpoint of transposition cryptography such as acrostics. In this paper, we looked at tanka and short poems from mathematical scientific cryptography viewpoint, and used the unicity distance defined by C.Shannon as the basis of the point of view. Here, we first saw the works of Fumi Saito and its English translation as consideration ciphertexts. Among them, from the interpretation processing of Short poems, the compose "key" is "feeling", etc., interpretation (or deciphering) "key" is "the author's background of the author, season word", or etc. , It is inferred that the unicity distance as English sentences is about 90 characters. We also try other similar considerations in Rilke's poesm and Basho's haikus, and discuss the possibility of interpretation (or deciphering) of tanka, short poem and haiku from the relationship between unicity distances and cryptographs that can be understood.

I analyzed the situation of small-scale academic societies on 4 points: needs, accounting, organization's life span and business contents. As a result, the small-scale academic society has 4 points: (1) they are necessary (2) there is a problem in the shortage of funds and members, (3) the life expectancy of the academic society is longer than that of the company (4) the business contents is only in the short term . Therefore, it seems that it is possible to increase the sustainability of small-scale academic societies by (1) diversifying the source of funds and (2) having a mechanism to examine whether the direction of the academic society is correct or not.

In this study, We studied the land-use change based on the digitalized land-use maps of the past and the present in Taipei, the most urbanized city in Taiwan. Next, using Landsat-5 /TM, the surface temperatures in two periods were extracted to evaluate the influence of the land-use change in the land-use on the distribution of the surface temperature. As a result of evaluation, the urban areas tended to be relatively higher in surface temperature than the other land-uses. It also confirmed that the other land utilizations had a higher temperature as they were located closer to an urban area. This might be explained by 1) The fact that the land uses located closer to an urban area include more constituent components of an urban area (such as asphalt and concrete) than land-uses located far from an urban area or 2) The possibility that the digitalization of the land-use maps might produce inaccurate positional information that did not match with the positional information of the surface temperatures. This suggested that border areas between different land uses should be carefully treated and examined for accurate evaluation on the relationship between the land-use change and surface temperature.
