Currently, climate change is regarded as one of the most important environmental issues in the 21st century. However, climate change education is not seriously carried out in schools. This study is concerned about enhancing students' recognition about climate change and actions responding to climate change through an history discipline. More specifically, this study tried to identify the effect of history lessons on environmental education, especially focused on climate change, by performing an experiment. The experiment was designed based on Solomon four-group design and carried out in one high school in Gwangmyeong city. Findings of the experiment are as follows. First, students who had taken the reorganized history lesson based on climate change - that is, students with experimental treatments - gained higher understanding of climate change than before and students of control groups. Second, students with experimental treatments gained higher understanding about relationship between history and climate change. Third, students with experimental treatments showed higher possibility of taking responding actions to climate change. In conclusion, history lessons reorganized with environmental issues, for instance climate change, have big potential for environmental education since they contribute to enhancing environmental recognition and prompting responding actions through exploration the effects of existing historical facts. Interdisciplinary approach like that taken in this study will provide students with more comprehensive and extended prism for the environment.

This study is on the pedagogical convention of architectural history in Korea, especially that of Western Architecture. Recent institutional change in architectural school in Korea has caused overall restructuring of academic program. In spite of extension in the field of history there was no progress of method and way of thinking. There is no change in the point of view to see the western architecture and its history as a unique and specialized phenomenon in the civilization of mankind. Because of no recognition about for what, for whom, and how to, and because of orientalism, the cultural position of western architectural history and its narrative was not asked. With the help of post-colonialism, de-constructivism and critical historiography this paper tries to show the fundamental premise of western architectural history as a myth and show its prejudice as not being justifiable. The background of the discourse there has been a representation effect with regard to knowledge as a power. we need to escape from this kind of cognitional frame With the analysis of the its premise and narrative we can find it is a historical construct that was made in the age of imperialism. In fact it has a lot of false information and problematic point of view. The Identity and originality of western architecture and its history has no logical reason or foundation if we think that it depends on the difference and comparison with other civilization. For example the explanation of its historical origin western architecture has big difference with Islamic architecture in spite of the resemblance each other. This paper try to show several reasons that discourse of western architectural history can not be survived any longer. So we need to reconstruct new pedagogy with deconstruction for the students of non western, or Korean students. Because it has important effect to see and think about architecture and its history.

Storing large amounts of data has always been a big problem from the beginning of computing history. Big Data has made huge advancements in improving business processes by finding the customers' needs using prediction models based on web and social media search. The main purpose of big data stream processing frameworks is to allow programmers to directly query the continuous stream without dealing with the lower-level mechanisms. In other words, programmers write the code to process streams using these runtime libraries (also called Stream Processing Engines). This is achieved by taking large volumes of data and analyzing them using Big Data frameworks. Streaming platforms are an emerging technology that deals with continuous streams of data. There are several streaming platforms of Big Data freely available on the Internet. However, selecting the most appropriate one is not easy for programmers. In this paper, we present a detailed description of two of the state-of-the-art and most popular streaming frameworks: Apache Ignite and Hazelcast. In addition, the performance of these frameworks is compared using selected attributes. Different types of databases are used in common to store the data. To process the data in real-time continuously, data streaming technologies are developed. With the development of today's large-scale distributed applications handling tons of data, these databases are not viable. Consequently, Big Data is introduced to store, process, and analyze data at a fast speed and also to deal with big users and data growth day by day.

This article conducted an pilot study on Lee Gyu-Jun(李圭晙)'s life and thoughts. He championed, and is mainly based on, old annotations of ancient Confucian bibles古文 that were made in the Han漢 and Tang唐 era in Chinese history and consequently took additionally into account Zuxi朱熹's annotations on Confucian bibles. This cause big trouble to him in conservative Gyeong Shang Province(嶺南). He participated in the Confucian Religion Movement孔敎運動 and proposed constitutional monarchy as a new polity fit for changing Korean history. He closely interacted with many resistants to the Japanese rule of Korea and had a mixed perspective on Western culture, science and technology, and social system, positive or negative, contingent on cases. He made great footprints in the history of both modern Korean medicine and philosophy. Thus there is an urgent need for the overall study on Lee Gyu-Jun in every aspect.

One of the most notable architectural aphorisms in modern period must be undeniably Louis Sullivan's, 'Form Follows Function.' The aphorism has been not only an important source of new aesthetic but also an formal principle of machine age. Other most famous source in order to justify modern aesthetic was the short essay by an cynical critic, Adolf Loos(1870-1933), 'Ornament and Crime' of 1908. Apart from what the essay asserted it is also famous for the influence of Sullivan's architectural notion during Loos' States staying. For Architectural historians of the early 20th century this connection is so useful to create a legacy of modern architecture. The historians seemed to believe that Loos understanded Sullivan's aphorism on which the historians wanted to focused. When we however look into two buildings designed and built in the period of publishing both aphorism and essay there must be a big fissure between the buildings and the historians interpretations. With this view point this study aims at showing the true meanings of Sullivan's aphorism and Loos' essay and also the big difference between the machine age's aesthetic and theirs.

The Cowherd Star and the Weaving Maid Star have been famous stars in East Asian countries. Nowadays Altair is defined to be the Cowherd Star in public materials including science books, mass media, public outreach programs, and movies played in public planetariums and science museums. However, in astronomical books and star-charts in history, the Cowherd Big Star (牽牛大星) has been known to be Dabih or $\beta$ Cap in the constellation Capricorn, and the asterism Cowherd consists of six stars including Dabih. Since the same title is given to the different objects simultaneously, considerable misunderstanding and confusion among the public have occurred. In this paper we consider this problem in two aspects. One aspect is which star has been defined to be the Cowherd Star in ancient literatures; the other is which stars were regarded as the Cowherd or the Cowherd Star in the historical records of occultation or conjunction in History of Koryo, Annals of the Choson Dynasty, and Daily Records of Royal Secretariat of the Choson Dynasty. As a result, we see that Altair has been regarded as the Cowherd Star in folklore and literature, but Dabih has been defined to be the Cowherd Big Star in astronomical works. An explanation proposed by previous researchers on the reason why such double meanings have been appeared is introduced. In the explanation, the fact that the Altair was defined as the Cowherd Star in ancient times had not been handed over properly, and the name of Cowherd was later put to the Dabih and its surrounding five stars to form one of 28 lunar lodges. Based upon these facts, we suggest the following ideas: (1) Altair should be introduced to be the Cowherd Star in public-friendly programs, and Dabih should be noticed to be the Cowherd Big Star in the field of history of astronomy. Dabih should be added as the astronomical Cowherd Big Star in academic books such as a dictionary of astronomical terminology. (2) The Korean pronunciation for Altair should be al-tear instead of al-tairu in accordance with the definition in the astronomical terminology dictionary compiled by the Korean Astronomical Society.
