This study aimed to analyze the evolution of general ideas concerning the element and the atom. In the scientific viewpoint, the modern idea of the element has been variously revised by the ancient Greeks, Boyle-Lavoisier, and Dalton. The definition of the atom was confused with that of the element from the ancient Greecian era to Lavoisier's era. The definition was also changed by Dalton and Rutherford. An analysis of the definitions of element and atom as presented in science textbooks for secondary school students and in general chemistry textbooks revealed that these definitions from diverse eras are confusing and inadequately explicated. The definition presented in one textbook was contradictory to the definitions in other textbooks. This tendency has been sustained in the textbooks from the 4th to 6th science curriculum. Therefore, we need to clarify the definitions of element and atom in order to help the students gain a better understanding of these scientific concepts.

The purpose of the case study is to understand changes in the teaching practices of two secondary science teachers during the span of their careers. To investigate changes in teaching practices, this study focuses on changes in the science teachers' practical principles based on Elbaz's practical knowledge. The biographical approach was adopted because teachers' voices are a valuable source to understand their professional development. In-depth interviews and classroom observations were conducted for two science teachers with seven years' and ten years' teaching experience. The major findings are as follows: First, participants' teaching practices changed through interaction with three factors, critical experiences that have stirred changes in teaching practice, teacher's reflection on teaching, and various experiences to make specific teaching practice changes. Second, three different change aspects of practical principles were revealed; reinforcement of existing practical principles, replacing old practical principles with new one, and generation of new practical principles.

In the perspective of hybrid, design contains confused forms and styles. Thus, the question is what 'decisively affects' on life, happiness and peace of human beings: In the past scientific ecology that tries to solve the problem in the aspect of functional design was important. Now the question is beyond the scientific ecology because human has a different way of environmental adaptation from animals. From this point of view, design is defined as something beyond materialistic standard. Terry Eagleton said, 'Creative ability deviating oneself and transcending is the very standard to measure human beings' A tendency to hybridize one's own section off genre or pursuing dismantlement is found on such creative perspective. In other words, it focuses on making a space of human's cultural behavior by unifying creatively natural environment and architecture space in the organic aspect. Such phenomenon provides a new chance and possibility in environmental design through a new molding experiment according to the development of digital technology. As experiments of environment design using digital technology are actively implemented, ecological and cultural views hybridize to create a new cultural space of various functions and features. Such experiment in environment design highlights the connections of ecological view, recognition of value, and relation-centered ideas, and enables a tool pursuing a new cultural development. This study focuses on the paradigm of such digital hybrid design and purposes to set the system by analyzing the application styles and principles of environment design through theoretical and case studies. In addition, it promotes a new possibility to develop environment design in the history of civilization.

The monthly news and culture magazine, 'Sasanggye,' established by Jang Jun-ha from 1953 to 1970, served as a platform for government criticism and intellectual representation. The magazine created photographic-essays covering a variety of topics and utilized images as a visually impactful tool with news value. This paper aims to critically examine the photographic-essays within 'Sasanggye' as archival records, shedding light on their intrinsic value. Before delving into this assessment, the paper thoroughly explores the developmental process and characteristics of these photographic-essays. And based on the content divisions within the main text, the paper categorized the themes captured in the photographic essays into politics, economics, society, culture, and miscellaneous topics. It then introduced representative photographicessays. From an archival perspective, looking at photographs involves elucidating that photographs carry meanings beyond mere data. The photographic essays in 'Sasanggye' serve as photographic records providing evidence of 1960s Korean society and encapsulating crucial visual information. Furthermore, the photographic essays in 'Sasanggye' hold a historical significance in the aspect of Korean magazine documentary photography. The photo-essays in 'Sasanggye' carry worth in the history of photography and encompass evidential and informational values as photographic records.

Information users depend more and more on portal sites for Internet navigation. These circumstances are reflected in academic information market especially. As the path of contacting public knowledge information, many institutions of information creation and services are collaborating with portal sites. At this point in time, it is necessary to consider linking libraries services with portal sites. Especially university libraries which have been recognized as private facilities of each university must to be considered as public facilities of local community. So it is desirable to develop method for linking university library services with portal sites for revitalizing university library services. This paper presents methods linking library OPACs with portal sites, through surveying oversea's cases and situation of domestic portal sites.

The purpose of this study is to investigate the formation and development of science teachers' practical knowledge by life history. In the sociocultural perspective, a science teacher is a producer and consumer of knowledge. There were two secondary science teachers who participated in this study. Each of them had three to six years experience in teaching. They were familiar with the researchers because they had been to the same university or were colleagues with them in graduate school for several years. The two science teachers had formed their practical knowledge for their professional development based on their biographical backgrounds. Model of Life history and structure of personal practical knowledge were used as analytical tools. As a result, the science teachers' practical knowledge has shown a significant difference in the main concern and weight according to their life contexts. The science teachers' formation of their practical knowledge played a role as an important motive to improve their professionalism based on the teacher's life path. In addition to that, the science teachers' practical knowledge showed a tendency to be solidified with continuous reflection.

In this thesis, I pursued how the concept of documentary photography in Korea was formed, and how Koreans perceive the current mix of some concepts and how they are tracked that. Korean photography society, directly or indirectly, accepted the concept and format of documentary photography of the United States in which information and discussion of the history and concept by examining the process of being transferred to Korea are examined. Giroksajin(記錄寫眞) is a translation word of documentary photography which was a part of documentary movements in the United States of the 1930s, and are all based on that concept. When we order Korean documentary photography and the subject matter must be distinct, attitude toward the things should be based on the exact perceptions of this age awareness, to be able to give enough information, and finally moved forward to move the human emotion must be. When this condition is equipped with the photographers and archivists perspective is revealed clearly the social and historical records that are meaningful. Documentary photography is the subject of the photographers and archivists that want to record the important things, but what you can get in the records and the question of how to use it is also important. Korean documentary photography, not only records the things, just to have a meaningful supplement to get done the exact context of information production and led to the conclusion that the strengthening of documentation strategies.

Mun Il-pyeong(1888-1939) is famous for a nationalist historian led history into popular style to enlighten the public. This paper aims to overview the characteristic of Mun Il-pyeong's history based on prior studies on Mun Il-pyeong's works. The characteristic of Mun Il-pyeong's history shows us people centric trend based on a struggle of classes. For the people, he insisted that description of history should be easy and scientific for the people who are host of history. And Mun Il-pyeong insisted the harmony of nationalist history and positive history. This was a progressive attitude in writing history at that time. Another characteristic of Mun Il-pyeong's history is that he considered cultural history as important. Mun Il-pyoeng wanted to overcome the ashamed political history by cultural history. In this intention, Korean history was again born proudful by him. Mun Il-pyoeng pursued open nationalism, not ultra-nationalism by connecting with other world. This paper focused on the essential part of Mun Il-pyoeng's history. Many scholars think Mun Il-pyeong focused on Korean modern history or history of foreign relation. But I think Mun Il-pyeong attached importance to Practical Learning, Sirhak in late Joseon dynasty. Because Sirhak contained Mun Il-pyeong's academic intention, Modernism and Culturism dreamed from his youth age. Therefore he led so-called Joseonhak Undong meaning study of Sirhak. Studying Sirhak made Mun Il-pyeong open a new direction Korean modern history have to go.

The English language has developed from a language with optional subjecthood Into a language with obligatory subjecthood due to a general reduction of inflections. Two types of subject omission, pro-drop and conjunction reduction, have been reported in the history of English. Old English with rich inflections had both referential pro-drop and conjunction reduction. Middle English with much lesser inflections still witnessed pro-drop and conjunction reduction, but in such a decreasing way that modern English with a loss of inflections developed from Middle English hardly has either pro-drop or conjunction reduction. This paper explores both the phenomena relating to optional subjecthood in Old, Middle, and Modern English in light of the cognitive processes of the universal, hierarchical constraints that are assumed to be inherent in English speakers' cognitive fatuity. It is found that optional subjecthood in Old, Middle, and Modern English is correctly raptured in terms of the distinct rankings of the proposed constraints, and that it is closely related to whether each of Old, Middle, and Modern English has rich inflections.

Objective : This study was conducted to compare Sasang Constitutional Medicine (SCM) and Four Humor Theory (FHT). Method : 1. The theoretical comparison was focused on the central pillars of both theories, i.e., the theories of Hippocrates and his successor Galenos as well as Lee Je-ma. 2. Research papers on SCM and FHT were collected as follows. First, relevant papers were searched for using several electronic databases: Pubmed (http://www.pubmed.org.), NDSL (http://www.ndsl.kr/index.do), KISS (http://kiss.ksstudy.com), and RISS (http://www.riss4u.net.). Keywords were 'Sasang', 'constitution', 'constitutional medicine', 'humor theory', 'Hippokrates', 'Galenos', and "Dongeuisusebowon".In addition, relevant papers were searched for using the websites of The Korean Society for the History of Medicine(http://medhist.kams.or.kr), The Korean society of Oriental medical classics (http://www.wonjeon.or.kr), The Society of Sasang Constitutional Medicine (http://www.esasang.or.kr/new_home/main.htm),and The Korean Association of Oriental Medical Physiology (http://www.ksomp.or.kr). As a result, a total of 32 papers were included in the final selection. Result & Conclusion : In this study, a comparison was made between FHT and SCM in terms of physiology, pathology and therapy. We showedthat the theories share similarities as well as differences. However, in a practical sense, the two should be characterized based on their differences rather than their similarities. In conclusion, the two have something in common, but overall, they are remarkably different from each other.
