  • Partial charge is an important and fundamental concept which can explain many aspects of chemistry. Since a molecule can be regarded as neclei surrounded by electron cloud, there is no way to define a partial charge accurately. Nevertheless, there have been many attempts to define these seemingly impossible parameters, since they would facilitate the understanding of molecular properties such as molecular dipole moment, solvation, hydrogen bonding, molecular spectroscopy, chemical reaction, etc. Common methods are based on the charge equalization, orbital occupancy, charge density, and electric multipole moments, and electrostatic potential fitting. Methods based on the charge equalization using electronegativity are very fast, and therefore they have been used to study many compounds. Methods to subdivide orbital occupancy using basis set conversion, relies on the notion that molecular orbitals are composed of atomic orbitals. The main idea is to reduce overlap integral between two nuclei using converted orthogonal basis sets. Using some quantum mechanical observables like electrostatic potential or charge multipole moments. Using potential grids obtained from wavefunction, partial charges can be fitted. these charges are most useful to describe intermolecular electrostatic interactions. Methods to using dipole moment and its derivatives, seems to be sensitive the level of theory, Dividing electron density using density gradient being the most rigorous theoretically among various schemes, bears best potential to describe the charge the most adequately in the future.

  • Background: Although nuclear disaster is considered rare, its effects are serious, and we must prepare a system to enable an effective response. Materials and Methods: Since 2010, we have been offering a two-day seminar to provide current nurses and radiological technologists with basic knowledge and train them in radiation emergency medicine (REM) techniques. This training offers lectures to deepen each specialty from the perspective of REM, as well as exercises on ways to handle irradiated and/or contaminated patients. Participants were expected to treat patients according to the concept of REM. Results and Discussion: All participants learn to assess and decontaminate contaminated wounds through drills. The questionnaire survey for participants indicated that participants were satisfied with this training and wanted to attend again. Conclusion: We believe that this training course will provide a valuable opportunity for medical professionals to gain knowledge and expertise in REM.

  • This paper presents the concept design procedure of a floating-type combined renewable energy platform based on hydrodynamic analyses and is focused on the fatigue design of taut-type mooring lines of the platform. Two types of combined renewable energy platforms are considered: a combination of wind turbine, wave turbine and photovoltaic energy plant and a combination of wind turbine, current turbine and photovoltaic energy plant. The basic configurations are conceptually determined from the understanding of floating offshore plants, while the main dimensions have been determined based on a hydrostatic calculation. Fully coupled hydrodynamic analyses have been carried out to identify the motion characteristics of the floating body and the tension histories of the mooring lines. The tension history is used for the fatigue life prediction based on the rain-flow cycle counting method. For the fatigue life prediction, tension life curves from API and the Palmgren-Miner rule are employed.

  • In the construction field, there has been a recent and unprecedented increase in the research and development of modernized Korean traditional buildings, This is because, in today's modern society, the basic needs for survival have already been met and more people are now recognizing the importance of the identity of our unique culture. It is therefore timeous to consider not just how to preserve and use Korean traditional buildings, but also how to develop them into more industrialized and modernized buildings in a practical way. Recently, the direction has been focused on the industrialization of modernized Korean traditional buildings, including their evolution, and development, as well as on the numerous cases where construction has been delayed. In order to industrialize modernized Korean traditional buildings, we need to standardize their form and actively introduce current IT (Information Technology). In order to achieve this, it is absolutely necessary to change from the CADD (Computer Aided Design and Drafting) system to the BIM (Building Information Modeling) system, which reflects the concept of Virtual Architecture. Therefore, the aim of this study is to discuss the possibilities of using BIM system for industrialization of modernized Korean traditional buildings, extend the foundation of the form library, and develop an intelligent modeler. It is also necessary to exemplify a case model for modernized Korean traditional buildings to which BIM is applied.

  • The housing policy of Korea has been pushed with a focus on the middle-class. This contributed to alleviate the absolute lack problem of housing, but this program for the housing policy of low-income brackets is also true as insufficient attention. Thanks to Bulk supply-oriented housing policy, the rising penetration of housing and living conditions are improving as a whole, but low-income housing problem has been exacerbated by a relative. National and local government will solve the residential housing problem of low-income brackets by expanding welfare programs, but the quality of existing housing issues and the alternative policy are regarded as insufficient. Homeless households in Korea are still nearly 400 million, Housing costs higher than income weighted for buying a home and rent payments of low-income brackets. In this study, I investigated the concept of low-income housing welfare and housing policy changes. This paper is aimed to present the basic data through the investigation and analysis residential status of low-income brackets.

  • Virtual Reality technology is divided two parts Panorama technology to imbody VR on space and Object technology to embody VR of things. About Object VR technology until present, they provided a cube access way, then observer can see object up, down, left, right side and zoom-in, zoom-out, but there is a fact that up-and-down expression is distorted or shows shortcoming that is not expressed by limited situation of manufacture way in Panorama VR's expression. Therefore, in this research, we examine the shortcoming that do not become top-and-bottom expression through basic concept of Panorama and Panorama VR manufacture process and do to propose cube type of new data format that permit up-and-down expression as a real world and compose Panorama VR space.
