Atom probe tomography (APT) has been fast rising in prominence over the past decade as a key tool for nanoscale analytical characterization of a range of materials systems. APT provides three-dimensional mapping of the atom distribution in a small volume of solid material. The technique has evolved, with the incorporation of laser pulsing capabilities, and, combined with progress in specimen preparation, APT is now able to analyse a very range of materials, beyond metals and alloys that used to be its core applications. The present article aims to provide an overview of the technique, providing a brief historical perspective, discussing recent progress leading to the state-of-the-art, some perspectives on its evolution, with targeted examples of applications.

According to the historical documents and paintings in many civilizations, rocks that fell from the sky fascinated humans as the message from the God or supernaturals. Scientific progress allows humans to recognize these exciting extraterrestrial objects as meteorites. Meteorites contain a wealth of pivotal information regarding formation of the early Solar System. Meteorites also provide broader scientific insights on, for example, the origin of life, interplanetary transfer of life forms, massive depletion of biosphere on Earth, and evolution of lithosphere on Earth-like planetary bodies.

The purpose of this study is to understand the meaning of architectural history of designated cultural properties of modern educational facilities through the analysis of its status. This study considerate acceptance and evolution of modern educational facilities during the about seventy years from 1895 to 1965. Also, this study analyzes items that is distribution of construction and designation year, regional groups, and status of main structure material, status of conservation and utilization of facilities, its characteristics of architectural style. In this study, the result of analysis show that most analysis items of investment buildings are tend to biased and concentration to one direction. Accordingly, designated cultural properties of modern educational facilities are weakly express architectural representation and symbolism in the period of modern educational acceptance.

This article explores the historical evolutionary process of the biopharmaceutical industry of Korea, and how intentional and unintentional policy interventions have triggered the creation of the industry's system dynamics and paved the way for the generation of a few global leading products, including biosimilar, as well as next-generation therapeutics of gene and cell. The policies cover the simple technology transfer of API synthesis to overcome the endemic parasitic disease, new substance patent adoption and new drug development consortia, human resource development, various national initiatives influenced by the Human Genome Project, and venture promotion schemes. The scope and implementation tools under these policies have been aligned and refined to transform traditional fine chemical-based pharmaceuticals, to stimulate large companies' participation and to create technology-based venture companies in the biopharma business of Korea.

Paper folding is a versatile tool that can be used not only as a mathematical model for analyzing the geometric properties of plane and spatial figures but also as a visual method for finding the real roots of polynomial equations. The historical evolution of origami's geometric and algebraic techniques has led to the discovery of definitions and properties that can enhance one's cognitive understanding of mathematical concepts and generate mathematical interest and motivation on an emotional level. This paper aims to examine the history of origami geometry, the utilization of origami for solving polynomial equations, and the process of determining the real roots of quadratic, cubic, and quartic equations through origami techniques.

Four species, Colpotrochia bifasciata, C. munda, C. pilosa sinensis, and C. uchidai, are newly recognized in South Korea. The genus Colpotrochia Holmgren, 1856 is a large group of the subfamily Metopiinae, in Ichneumonidae, and contains 62 described species worldwide. Among them, nine species have been recorded from South Korea. The South Korean Colpotrochia was started from by Uchida in 1930. A comprehensive historical review of the faunal study of this genus in South Korea have been done by Kim and Japanese entomologists in the period of 1955-1966. In this study, diagnoses of four unrecorded species and illustrations of diagnostic characters are provided. The current total is 13 species of this genus known from South Korea.

This study aims to examine the evolutionary process of the protection-management system for historic monuments and their surroundings in France over one-hundred years. Because France and Korea shared policies and institutions regarding the management of historical monuments (cultural property) along with their surroundings, it is necessary to explore the French experience from a comparative perspective. In France, historical monuments began to be recognized as national heritage according to "the 1913 law" which has continued to evolve for more than one hundred years. In the beginning, a historical monument was preserved as a single building unit; however, since 1943, a new policy has been implemented to preserve sets of historical monuments along with their perimeters of protection zones. Moreover, since 1980, in the context of decentralization, local authorities have been given more roles and autonomy concerning the management of historic monuments and their surroundings. Local authorities have played a key role in the protection-management of historic monuments and their surroundings, and have become more active in the conservation of their architectural heritage, including historic monuments. The central government, however, remains as the headquarters whose rigorous policies provide a solid foundation for the decentralized management system of architectural and cultural heritage, including historic monuments. The final goal in the evolutionary process, then, targets the effective and harmonious integration of the protection-management system for historic monuments and their surroundings into urban and regional planning.

This research is a theoretically grounded empirical study aimed at shedding light on the policy evolution of Technology Park(TP) in term of historical institutionalism in South Korea for the 16 years. The study analysed the evolution of TP, and the empirical fieldwork was completed in two regions, Gyeongsangbuk-do ana Daegu City. Historically the policy can be divided into three periods being affected by endogenous and exogenous impact. This research found that the functions of local TPs changed as following: six functions decided by central governments ${\rightarrow}$ added the role of supporting regional innovation ${\rightarrow}$ comprehensive support for small & medium-sized enterprise. Analysis of the empirical study reveals significant findings: first, the relationships between central government and local actors which was built in the quickening period have been path dependency. Second, the functions of local TPs were evolved with the characteristics of layering and reorientation of the institutions. Thirdly, there were some differentiation between the two regions because of the milieu, though the central government had the power deciding the functions.

What is 'nation' and 'nationalism?' What does 'korean nationalism' mean? And how is korean nationalism represented through a chain of films called 'the korean blockbuster films?' The purpose of this study is to answer to these questions. The characteristics of the korean blockbuster films have been studied for quite a long time and the researchers have agreed with the context about nationalism in a large sense. However, majority of the studies ends up in the journalistic or impressionistic criticism without any theoretical discussion. Few theoretical criticisms also have founded on the formation process of nation of the Western Europe and their nationalism. Hence I would like to add the discourse of korean nationalism and to seize more accurately the social/cultural/historical peculiarity of the korean blockbuster films. In addition, as non-nationalist narratives have recently emerged, korean blockbuster films are entering to the evolution process. On this, the significance of this study seems to exist in providing a cornerstone to the expected evolution theory of the korean blockbuster films by means of complementation and reestablishment of nationalism of their first generation. and , presenting socio-historical peculiarity of the Korean nation, are examined by the close textual analysis.
