As the number of Internet users exploded, attacks on the web increased. In addition, the attack patterns have been diversified to bypass existing defense techniques. Traditional web firewalls are difficult to detect attacks of unknown patterns.Therefore, the method of detecting abnormal behavior by artificial intelligence has been studied as an alternative. Specifically, attempts have been made to apply natural language processing techniques because the type of script or query being exploited consists of text. However, because there are many unknown words in scripts and queries, natural language processing requires a different approach. In this paper, we propose a new classification model which uses byte pair encoding (BPE) technology to learn the embedding vector, that is often used for web attack payloads, and uses an attention mechanism-based Bi-GRU neural network to extract a set of tokens that learn their order and importance. For major web attacks such as SQL injection, cross-site scripting, and command injection attacks, the accuracy of the proposed classification method is about 0.9990 and its accuracy outperforms the model suggested in the previous study.

This study is to analyze correlation between Daniel Libeskind's architecture works and the effects as a series of music works be learning in youth and opera "Aron and Mose". The results showed that First, Libeskind created convergence of invisible line by borrowing the composition of freely flowed scales in score from his architecture. Second, he composed geometrical shapes of contrapuntal reiteration based on double tune in music structure, in other words forms of polyphonic proportion. and he expressed the geometrically, freely line rhythm by planning composition of multidimensional spaces, "Hybrid", planning the contrast of material, form by results of Intertextually combination between Architecture and Music. Third, he tried to express the pain, fear, anxiety, etc. of the past spatially, and constructed "the spaces of absence" on his works through inspiration from Arnold Sch$\ddot{o}$nberg's works.

The purpose of this paper is to suggest one of effective online questionnaire methods by using web based games. The research examines the interrelation between space design element and emotion language in the background actually used in the web games, and suggests new questionnaire methods to overcome the problems of the insincere answers which is the limitation of online questionnaire methods. The paper is to examine the related references, and compare the merits and demerits between printed and online text based questionnaires. Then it suggests the on-line questionnaire methods based web games which can improve errors of the demerits. The emotional words and phrases database is embodied by the interrelation between the emotional words and four spaces such as a dwelling, a tradition, a commerce and a fantasy based on the position decision value of Gaussian distribution. The paper suggests to be utilized for a population calculability system such as a consumers preference test.

This paper aims to analyze English vocabulary of the North Korean textbooks diachronically using the constructed English textbook corpus. The North Korea English textbooks attained from Information Center on North Korea of the Ministry of Unification are divided into before and after Kim Jong-Il era for the year of 1996 in which the curriculum revision has been conducted. They are stored as text files to analyse vocabularies using WordSmith Tools 7.0. The vocabulary size of the revised textbooks increased after the curriculum reorganization, but the number of vocabulary types and vocabulary diversity decreased. After the curriculum revision, it was found that lots of vocabulary related to the establishment of the Kim Jong-Il system appeared as the keyword. It was also found that some vocabularies reflected the economic and social life of North Korea. In addition, through comparison of the 100 high-frequency word list and keywords, it can be concluded that the vocabulary of the English textbooks of North Korea is gradually changing into communicative contents from contents related with written language.

The development of weapon systems (or components) is hindered by the number of tests due to the limited development period and cost, which reduces the scale of accumulated data related to failures. Nevertheless, because a large amount of failure data and maintenance details during the operational period are managed by computerized data, the cause of failure of weapon systems (or components) can be analyzed using the data. On the other hand, analyzing the failure and maintenance details of various weapon systems is difficult because of the variation among groups and companies, and details of the cause of failure are described as unstructured text data. Fortunately, the recent developments of big data processing technology, machine learning algorithm, and improved HW computation ability have supported major research into various methods for processing the above unstructured data. In this paper, unstructured data related to the failure / maintenance of defense weapon systems (or components) is presented by applying doc2vec, a machine learning technique, to analyze the failure cases.

This paper examined the immanent ideological bases in the transformation motif of animations, focusing on several leading animation works in which a human gets transformed into an animal, or vice versa, and also took a look at what meaning and function this transformation motif adds to their narrative. As a result of analyzing the animation texts centered on the transformation motif, transforming into an animal in is applied as a means for punishment. It shows the notion that the animals need men's care, that is, the anthropocentric point of view that the animals need to be overcome and conquered had a strong influence upon this work. However, in , a boy realizes that the animals(nature) are not the targets to conquer and learns to appreciate the principle of Mother Nature through the process of becoming a bear. By this description, this work shows deep reflection on nature and human being. Lastly, shows a desire to overpass the border to forbidden things, and describes the relationship between men and animals(nature) in a variety of perspectives. Furthermore, this study examined how the variety of attitudes toward the transformation targets is formed in each work.

The object of this study is to investigate how to effect on the response characteristic if the image were used in the internet survey about the social issues. Especially in case of the social issues with pros and cons opinions, the effects of the image on the response characteristics were investigated. In this study, the response attitude of the 4 different groups to 3 social issues was measured at March, 2013. The 4 different groups are following: group with only text information, group with positive image, group with negative image, and group with both image. It is shown in the outcome of analysis on survey that the group with negative images tend to respond negatively and the group with positive images tend to respond positively. It means the priming effect. As a conclusion of this study, if the image were used in the social investigation, the image should be selected discreetly and the effect of image should be reflected in the analysis in consideration of the priming effect of the image.

The aim of this study is to apply latent semantic indexing(LSI) techniques for efficient automatic classification of opinionated documents. For the experiments, we collected 1,000 opinionated documents such as reviews and news, with 500 among them labelled as positive documents and the remaining 500 as negative. In this study, sets of content words and sentiment words were extracted using a POS tagger in order to identify the optimal feature set in opinion classification. Findings addressed that it was more effective to employ LSI techniques than using a term indexing method in sentiment classification. The best performance was achieved by a supervised LSI technique.

This paper analyzes if the rapidly increasing cyber universities' remote education provides services based on web accessibility standard and suggest the direction to reduce information difference between people. It selected 10 cyber universities recognized by the government and analyzed the application situation of the web accessibility using' A-Prompt', an evaluation and analysis tool for web accessibility focusing on factors that can be evaluated technically. It also compared it with $\ulcorner$cyber universities remote education web accessibility result$\lrcorner$ performed in 2006 to confirm if the accessibility is improved according to 'web contents accessibility instruction (KWCAG) 1.0. The result shows that the items such as the use of text and the support of supplementary explanation tool have improved. But it was analyzed that it is difficult for people to use web contents provided by domestic cyber universities. So the educational contents' accessibility application must be considered to solve such problems and publicize the remote education.

This study explored the phenomenon of heterosexual women embracing Boys' Love manga within the heteronormativity context from a feminist psychological perspective. Specifically, the issue of genre characteristics of Boys' Love manga, women's psychological mechanism of reading Boys' Love manga, and the functions and effects of embracing Boys' Love manga were discussed. As a theoretical framework of analysis, I started from the classical psychoanalysis and critically adopted the concepts of the various camps of feminism, queer theory, and Huizinga's Homo Rudens. The results show that Boys' Love manga can be classified as a sub-category of the romance genre, which fulfills heterosexual women's desires of eternal love and equal partnership. From these wish-fulfilling fantasies, heterosexual women attempt to be decontextualized from the heteropatriarchism, to enjoy distancing and voyeuristic separation from the characters in the texts, and to disturb the dichotomous gender system through gender reversal identification. These processes, which can be regarded as a women's play challenging sexual rigorism, ultimately bring about an awareness of the female sexual subjectivity.
