This study aims to explore how Korean middle-school mathematics textbooks on functions provide students an opportunity-to-learn [OTL]. For this purpose, we investigate 3 textbooks in terms of mathematics content and practice, the level of cognitive demands of mathematical tasks, types of student responses, types of context-based tasks, and connections among the tasks. The findings from the data analysis suggest as follows: a) an opportunity-to-learn to connect procedures to functional concepts and new ideas of functions to the existing one is very limited; b) the textbooks seem to provide students an OTL to understand functions as definitions, rules and conventions and to experience repeatedly procedural executions through worked examples and mathematics tasks; c) students may not experience to explain their own ideas/thinking by using mathematical sentence or justify their own cognitive processes; and d) students can be exposed to get a sense of mathematics as a set of fragmented and isolated facts or procedures, rather than to encourage to expand and deepen their understanding of functions.

This paper proposes a method to learn action patterns of opponent characters for intelligent characters. For learning action patterns, intelligent characters learn the past actions as well as the current actions of opponent characters. Therefore, intelligent characters react more properly than ones without the knowledge on action patterns. In addition, this paper proposes a method to learn moving actions whose fitness is hard to evaluate. To evaluate the performance of the proposed algorithm, we experiment with four repeated action patterns in a game similar to real games. The results show that intelligent characters learn the optimal actions for action patterns and react properly against to random action opponent characters. The proposed method can be applied to various games in which characters confront each other, e.g. massively multiple of line games.

Korean wave which started from Korean drama is continuing its popularity with K-pop in China. This positive effect has lead to increases in Korean product export to China, increase in number of Chinese visitors to Korea and increase in number of Chinese population learning Hangul. In this research, empirical study was conducted to analyze the influence of Korean wave contents (drama, movie, K-pop, games) on Chinese population (their intention to purchase Korean product, visit Korea and learn Hangul.) As the result, it is understood that the most influential Korean wave content on Chinese population's intention to purchase Korean cosmetic and clothing products is drama; it is analyzed that K-pop has noticeable influence as well. Korean drama has the greatest influence on Chinese population's intention to visit Korea, purchase cosmetic or plastic surgery tour package and purchase Korean food. K-pop is analyzed as the second most influential factor among Korean wave contents in this category. Korean wave contents which have the most influence on intention to learn Hangul are Korean drama and K-pop, and it is analyzed that K-pop has greater influence than Hangul in this field.

In this paper, we analyzed the types of tasks presented in the 'Probability and Statistics' textbooks and how the cognitive competences required to perform the tasks provide students with opportunity-to-learn. To this end, the analysis of the 9 books of the 'Probability and Statistics' test textbooks according to the 2015 revised mathematics curriculum showed that the context-based tasks(CF type, RE type) ranged from 67.5% to 78.0% of the total number of tasks in each textbook, but the ratio of relevant and essential tasks related to real life is from 0.4% to 2.0%, it was found that most of the context-based tasks presented in the textbooks were disguised as real life materials. The cognitive competences of context-based tasks ranged from 29.6% to 50.0% in reproduction category, from 33.8% to 54.3% in connection category, and from 8.8% to 20.0% in reflection category. As a result, there was not enough opportunity-to-learn for students to experience reflective cognitive processes.

The purpose of this study is to analyze the actual realization of the opportunity to learn given to students by examining students' cognition for enrichment mathematics textbook tasks' levels of cognitive demand. First, we analyze characteristics and limitations based on the theoretical framework. Second, we examine students' cognition about the distribution of the mathematics textbook tasks' levels of cognitive demand. And we analyze how the opportunity to learn actually work. Third, in the sense that enrichment textbooks are textbooks for science school students, we analyze whether the opportunity to learn for gifted is offered. The conclusion is as follows: First, with respect to levels of cognitive demand, PNC tasks account most. Second, students also cognize that PNC tasks account most. Third, tasks for gifted are not offered and students also cognize that opportunity to learn for gifted is lacked.

The purposes of this study are：(1) to analyze the learning content & subjects on the area of clothing and textiles in Home Economics for Young Men： A Teaching Guide, (2) to compare it with the learning content & subjects on the area of clothing and textiles in Home Economics teaching guides in the middle school in Korea, (3) to provide preliminary data for developing the learning content & learning method on clothing and textiles education for middle school students. To implement these proposals, Home Economics for young Men： A Teaching Guide in U.S.A and 6 Home Economics teaching guides for the middle school in Korea are reviewed and analyzed. The research findings were as follows： 1. Home Economics for Young Men is characterized as including： (1) interesting learning contents for girls and boys in the middle school, (2) learning contents for helping students to work on their own initiative (3) learning contents related to actual life, (4) practical consumer education content related to clothing and textiles area, (5) learning contents for developing originality, (6) learning contents related to vocational education. 2. The subjects in Home Economics for Young Men give careful considerations especially on how to learn. They are based on the idea that middle school students have to learn and to solve the subject by themselves. 3. Learning contents on Home Economics teaching guides for middle school in Korea are different from learning contents in Home Economics for Young Men in the subject & the form of description, the subject matter of practice in clothing area, the standpoint of description on clothing matters. The subjects in Home Economics teaching guides for middle school in Korea don’s give careful consideration on how to learn. There are little idea that middle school students have to learn and to solve the subject by themselves.

The most threatening attack that has become a hot topic of recent IT security is APT Attack.. So far, there is no way to respond to APT attacks except by using artificial intelligence techniques. Here, we have implemented a machine learning algorithm for analyzing cyber threat data using machine learning method, using a data set that collects cyber attack cases using Scikit Learn, a big data machine learning framework. The result showed an attack classification accuracy close to 70%. This result can be developed into the algorithm of the security control system in the future.
