  • Technology of surface investigation using X-ray is one of widely used technology nowadays. This technique has been numerously used for planetary surface investigations for both orbital and rover scientific instruments. Korea has a plan to send an orbiter and lander to the Moon by the early 2020s. Therefore, the time has come for Korean researchers to develop major scientific instruments and start to do research on basic research for the Moon. Because of this situation, we firstly investigate X-ray technology, which is essential as one of core techniques of planetary remote sensing from the orbit and ground. This paper presents the current status of planetary exploration using X-ray techniques and new development of worldwide X-ray technology which could be adapted for prospective planetary missions.

  • Contemporary space design has based on the framework of academic standards on a number of scientific propositions in order to find out correlation of human and environment and closely examine approaches of a normative design. However the contents are enormous and introductory and have limitation of application to practical business affairs so that we will have to understand them as a thinking to explain the design with,. Therefore this study is an experimental research making use of concrete design approaches applicable to the area of space design ad cinematic construction as a medium. The purpose and significance of it lies in examining its validity and contributing to the future development of space design. Accordingly this study conducted the research through a literature survey for the understanding of space perception in the cinema deduced the language of design concept according to it examined the basic unit of cinematic construction then analyzed the cases of practical architectural spaces. The findings of this study indicate that human's perception to space and the cinema is deduced as a common conceptual language characterized by the ideas of articulation scenery and timeness. These concepts are very organic and interdependent and can probably become a means for human to appropriately analyze an behavior attribute type of investigating environment with. Also in composing space the basic units of cinematic construction can be as instrument to be easily applied to practical affairs as they are correlated with the function of space and a constituent language to be reasonably designed.

  • This research was intended to provide a method to improve competitiveness, based on the integration of basic municipalities by assessing changes in their population and local industry Municipalities were integrated based on the addressing system 市(Shi), 町(Chome), 村(Village) of Japan. As a result, an actual increase of the population could not be seen in the new municipalities formed by the integration of the basic municipalities. It is also found that the shipping volumes, number of companies, and the number of people employed by local industry, attracted by such municipalities, has steadily decreased. However, even though the proportion of industry-sharing in the local municipalities is not significant, it was found that the number of tourists has increased. Therefore, it is concluded that the strengthening of the connectivity between local industry and the tourism industry can be one of the principal methods to strengthen the competitiveness of these municipalities. In addition, it has been found that scientific research from a variety of perspectives and verification of data related to the effectiveness of integration of local municipalities is necessary.

  • Objectives: To establish scientific and objective evidence for the use of a Korean medicine, articles regarding Hwangryeonhaedok-tang (HRHDT), a herbal medicine frequently used in Korean medical clinics and hospitals, were gathered and analyzed. Methods: The articles were classified as being from domestic or international journals, and by their year of publication. The mechanisms of the anti-inflammatory and antipyretic effects of HRHDT were investigated. Results: Of the 25 articles analyzed, 7 were published from Korea, 7 were from China, and 11 were from Japan. HRHDT showed anti-inflammatory and antipyretic effects through the regulation of the expression of Th1 cytokines including interleukin-2 (IL-2), IL-8, interferon-${\gamma}$ (IFN-${\gamma}$), and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$); and Th2 cytokines including IL-4, IL-6, and IL-12, which inhibit leukotriene B4 (LTB4), cyclooxygenase-2 (COX-2), prostaglandin E2 (PGE2), and inflammatory cells. It also lowered preprodynorphin (PPD), and corticotropin-releasing factor (CRF) in the peripheral nerve system and hypothalamus. Conclusions: We speculate that the anti-inflammatory and antipyretic effects could be related to the therapeutic efficacy of HRHDT in removing pathogenic fire and heat.

  • Since Wertheimer and Leeper reported possible adverse health effects of magnetic field in 1979, worldwide researches on this issue have been conducted. More recently, the U.S. Congress instructed the NIEHS (National Institute of Environmental Health Sciences), NIH (National Institute of Health) and DOE (Department of Energy) to direct and manage EMF RAPID (Electric and Magnetic Fields Research and Public Information Dissemination) program aimed at providing scientific evidence to clarify the potential for health risks from exposure to extremely low frequency electric and magnetic fields(ELF-EMF). Although they concluded that the scientific evidence suggesting adverse health risks of ELF-EMF is weak, the exposure to ELF-EMF cannot be recognized as entirely safe. Therefore, the purpose of this article is to describe magnetic field 3-D calculation and to evluate eddy current of human body compare to international guide line recognized one of the basic problems. In open boundary problem, Magnetic field using FEM is not advantageous in the point of the division of area and the proposition of the fictitious boundary. Therefore, we induced the analytic equation of magnetic field calculations so but the finite line segment based on Biot-Savarts law Also, Eddy currents induced due to ELF-EMF magnetic field are computed. To calculate induced currents, impedance method is used in this paper, An example model of human head with resolution of 1.27cm is used. In this paper, We evaluate the magnetic field and eddy current of human head around 765 kV transmission lines compare to international guide line.

  • Artificial intelligence (AI), big data, and ubiquitous robotic companions -the three most notable technologies of the 4th Industrial Revolution-are receiving renewed attention each day. Technologies that can be experienced in daily life, such as autonomous navigation, real-time translators, and voice recognition services, are already being commercialized in the field of information technology. In the biosciences field in Korea, such technologies have become known to the local public with the introduction of the AI doctor Watson in large number of hospitals. Additionally, AlphaFold, a technology resembling the AI AlphaGo for the game Go, has surpassed the limit on protein folding predictions-the most challenging problems in the field of protein biology. This report discusses the significance of AI technology and big data on the bioscience field. The introduction of automated robots in this field is not just only for the purpose of convenience but a prerequisite for the real sense of AI and the consequent accumulation of basic scientific knowledge.
