This study aims to find out the argument structure which appears in the type of argument class (teacher- and student-centered) of the high school. The argument structure was compared and analyzed according to analyzing the study achievement and verified the academic achievement related to climate change. The results are listed below. First, the student-centered class is more effective method through the result that analyzed the class type of the teacher in argument-centered class. This result is to suggest more effective method to revitalize the argument activity of students-centered class which students plan for themselves and find more various materials. Second, teacher-centered class is more effective in contrast with argument analysis in the academic achievement test. While this is why the teacher-centered class utilizes an essential data necessary to curriculum in the argumentation, the elements to form the argument increased because students utilized the materials with their interest and concern in the process of proving in the student-centered class. Through the results of the research, it is necessary to develop the argument-centered programs for the science class and the curriculum-centered materials for argument class activity.

The Fourth Industrial Revolution era requires people to have the ability of integrated thinking, critics, sensitivity, and creativity in an integrated manner. Therefore, teaching methods are expected to become more suitable for the trend. In this belief, current teacher-leading education method should move to students' self motivating one and consist of programs in which students voluntarily involve. In this reason, this study suggests FPBL educational method model that is combines project-based learning with flipped learning by analysing preceding research and digital painting tool class was designed by applying it. As a result of applying the designed class model to the class, all of the class satisfaction, effectiveness, and interaction were evaluated positively. Problems such as limitations of project classes due to non-face-to-face classes, large amount of learning before class, and reduced concentration during class were found. Therefore, when the FPBL class model is conducted non-face-to-face, it will be necessary to further strengthen the role of the instructor, provide lecture videos summarizing the core contents, and improve concentration by providing active participation and fun using various digital tools. The result of the study looks significant by confirming the possibility of applying FPBL model not only in design education but also other educational settings.

This paper has attempted to examine the political and operational contexts within which North Korea's latest acts of nuclear blackmail, its test-firing of an SLBM on April 23rd 2016 and its fourth nuclear test on January 6^th 2016, should be understood. Analysis of the KN-11 SLBM and the Sinpo-class SSB is based on official South Korean, US and others sources, especially the ROK MND, as well as other resources from South Korea, US and others. Unfortunately, the results of this exploration are inconclusive: there is simply not enough evidence available at present to either confirm or refute the existence of a functional North Korean SLBM and SSB. Nevertheless, the North Korean determination to possess such assets should not be taken lightly. But even accepting North Korea's claims about its SLBMs at face value, which is undermined by news of apparently unsuccessful follow-up test-firings in November, and probably December 2015, there is little proof that North Korea has yet succeeded in miniaturizing its nuclear warhead, so the most extravagant fears are not yet justified. Taken together with North Korea's latest announcement of a supposed successful SLBM ejection-test, on March 23^th 2016, the KN-11 SLBM claims should probably be seen as primarily about proving North Korea's status as a nuclear power, both to exert external political pressure and to bolster internal political support for Kim Jong-un's rule. In conclusion, this paper recommends formulating a preemptive anti-access strategy for the ROKN, proposes acquiring an ASW CV and SSNs to implement submarine strategic deterrent patrols, and urges extending the existing limited AORs to facilitate the preemptive anti-access strategy. Other deterrence options may be suggested, but it is surely significant that the ROKN has recently publically referred to the deployment of an ASW CV and SSNs for the first time.

Mathematics and science are very closely related. Among the science areas, physic is strongly linked with mathematics. As the related mathematics skills were alloted later than the science contents in the national curriculum, students often suffer from science classes. Accordingly, an opinion have been claimed to teach the related mathematics skills prior to the science classes. However, it would be hard to arrange all science and mathematics contents in order. Instead of that, in this research, we taught students mathematics contents that are crucial for learning speed through science classes. We called that teaching strategy an integrated science and mathematics class. Then, we examined students' achievement in science as well as skills of mathematics to know the effectiveness of the strategy. We found that the average mathematics score of the whole class went up meaningfully. We also found that their science achievement was above than basic level. Moreover, the homeroom teacher of the students observed 3 aspects which showed the students were better than previous students. Finally, we divided the students into 4 groups by their science and mathematics achievement score and interviewed each group. As a result, we knew that interesting and confidence in science and mathematics quite exerted influence on their achievement.

This study aims to investigate the effects of learning strategy-based early reading instruction for English underachieving students. For this purpose of the study, sixteen learning strategies were driven from the review of previous related literature and the result of the survey conducted to the students and the teachers. Strategy integrated early reading instruction was implemented to nine students for thirteen weeks. The word recognition test was conducted before and after the instruction to examine whether the instruction had effects on the increase of their early reading skill. In addition, in order to investigate certain change in students' affective aspects after the instruction. The research conducted survey to the students. A teacher's field note and students' class journal were also analyzed to verify the results from the quantitative test. The results indicated that the instruction led to the increase of students' early reading skills. It was also found that the instruction motivated the underachieving students to devise a strategy for their learning process.
