  • The objective of my paper is to investigate historical change in concepts of medical geography and to present its historical vision. Modern medical geography was established in the name of medical topography in Europe where it had to control tropical diseases in the course of exploration and voyages for colonial interests. England developed medical geography in the name of sanitary reform, France did so for civilizing mission, and geomedicine prevailed in Germany. The twentieth century witnessed two traditions of medical geography, with focus on disease ecology and medical care system, respectively. In addition, the paper emphasizes the significance of cartography of disease as knowledge as power. As the identity of place becomes increasingly important in relation to health at the around of the twenty-first century, geography of health has emerged as a new promising discipline independently of medical and public health geography.

  • The purpose of this research is to explore the possibility of geographic education by implementing the map-based geographic education site which mashed up with Google earth by referring the various materials of geographic education which exist in on-line and off-line. In recent years map-based geographic education is required by the radical change of geoweb environments, but there have been few researches in this field. This research is folded up as follows: First, we designed the contents through the textbook analysis and then collect various data related to the contents such as pictures, video clips, conceptual map, etc. which are required to explain the concept. Second, we mashed up the collected data on the Google earth by using the Google's open API. Third, we implemented the geographic education website based on the classification of contents in textbook and the various collected data. This research is important in both that it explores the possibility of the map-based education rather than the text-based education in the geographic field which handles mainly the space and finds the best method to express the various concepts of the textbook on the geoweb environments.

  • The flame deflector should be constructed to minimize the induced environmental effects on the launch vehicle and to minimize the exhaust impingement effects on the launch complex structures during the lift-off operation. Therefore, it should be designed to avoid recirculation and reverse flow of rocket exhaust plumes. The circumstance around launch complex and characteristics of launch vehicle should be taken into consideration for the flame deflector design. In this paper, we designed the flame deflector reflecting KSLV-II 1st engine characteristics and analyzed the effect of exhaust plumes related to change geometry by means of computational flow analysis.

  • Recently, the importance of ISP(Information System Planning) has been increased because of rapid change and severe competition in business environments. Furthermore, the role of IS in the organization has included not only the supportive activities but also the strategic activities. Organizations can get the competitive advantages through the strategic use of IT by establishing effective and systematic ISP implementation. The main focus of this study is investigate the relationship among three subunits(organizational factors, the role of IS and effective ISP) based on the contingent settings which the process of ISP is implemented. The reasons that conceptual framework of this study is based on the contingent theory are as follow: First, ISP process itself has a series of complicated work which various elements in a company are involved. ISP externally must have the process to evaluate information technology (technology related with IS). Internally ISP process has a serious of works including determining information requirements to develop successful IS for other functional departments and identifying strategic opportunity of IS aligned with business strategy. Secondly, the activity of ISP is occurring on the continual basis. Business environments in which ISP process has implemented are changing continuously. Specific ISP methodology which was appropriate in a certain period of time does not work any more because of the rapid changes in business environments. For this reason managers can hardly expect successful ISP without considering external environments or internal environments such as organizational or management side. For this study, 240 survey questionnaires were mailed and 71 questionnaires were returned. 57 samples were used for the final analysis and 14 samples were excluded from analysis in that they didn't exercise official and systematic ISP. As the result of analysis, among the internal factors(organizational size, time frame of decision making, budget, management style, organizational culture) organizational culture, management style and time frame of decision making are identified as contingent factors on the effective ISP. The result of this study may have meaning in suggesting the way to develop effective ISP through the formalization of business process, more favorable users attitude toward IS and selection of an appropriate ISP methodology.

  • Integrated gasification combined cycle (IGCC) is an efficient and environment-friendly power generation system which is capable of burning low-ranked coals and other renewable resources such as biofuels, petcokes and residues. In this study some process modeling on a conceptual entrained flow gasifier was conducted using the ASPEN Plus process simulator. This model is composed of three major steps; initial coal pyrolysis, combustion of volatile components, and gasification of char particles. One of the purposes of this study is to develop an effective and versatile simulation model applicable to numerous configurations of coal gasification systems. Our model does not depend on the hypothesis of chemical equilibrium as it can trace the exact reaction kinetics and incorporate the residence time calculation of solid particles in the reactors. Comparisons with previously reported models and experimental results also showed that the predictions by our model were pretty reasonable in estimating the products and the conditions of gasification processes. Verification of the accuracy of our model was mainly based upon how closely it predicts the syngas composition in the gasifier outlet. Lastly the effects of change oxygen are studied by sensitivity analysis using the developed model.

  • This study, as discussed herein, tries to understand how modern commercial buildings occur and develop in certain type of social and cultural conditions. There are many words standing for modern society, of which the most remarkable one is 'commercial society'. Commercial society is where goods are manufactured to one's taste and consumption is a way of communication and a way of discriminating one from the others by using different code. Nowadays, architecture gets more and more popular and becomes commercial object which is intended to the sign of the social meaning. So, the sign of commercial buildings varies according to the social and cultural backgrounds and kitsch is applicable to it. The original meaning of kitsch, which usually is considered an inferior copy of an existing style, is examined and applied to architecture in order for comprehension. Throughout this study, the types of commercial buildings are selected and immanent meaning to the psychology of consumers as applicable to commercial buildings is considered. Also, the trend of kitsch in commercial buildings is analyzed by classifying the image and code of a building's shape. In a conclusion of the study, two major points can be found; commercial building has a significant meaning in terms of design, and commercial building is the conceptual result of a continuous change in the relationship between society and art.

  • With the advent of new media era we are living in the world of motion picture image is not an exaggeration. With the development of the mass media with images and moments that passed the day feeling like part of it is communication. In this era a sensual and shapeable image more than the logical and realistic thinking may be passed. In the act of seeing a moving image, prior to linguistic and conceptual meaning, color and screen configuration delivery and formative element in the change they produce is first recognized. Particular kind of video animation having the narrative structure, this territory effect greatly. the film even more significant effect on the area and linking the image of the scene transitions in the scheme also features a simple means of natural communication functions are being expanded. These transitional effects provide visual pleasure from a simple transition traditional methods. And In terms of narrative functions performed to help a narrative flow of availability, visual representation should continue.

  • The information society is characterized by rapidly increasing and changing information. Traditional models of learning and instruct on have emphasized forms of mastering the information in content domains. Storing information and being able to recall it has been central to formal education. But it is no longer possible to master content domains. This paper discusses constructivism as a shifting paradigm for educational research and practice in information society. Constructivism provides an alternative epistemological base to the objectivist tradition. Constructivism holds that there is a real world that we experience. However, the argument is that meaning is imposed on the world by us, rather than existing in the world independently of us. Meaning is seen as rooted in experience. The experience in which an idea is embedded is critical to the individual's understanding of that idea. From the constructivist perspective, learning is not a stimulus-response phenomenon. It requires self-regulation and the building of conceptual structures through reflection and abstraction. Problems are not solved by the retrieval of rote-learned right answers. The effective motivation to continue learning can be fostered by leading students to experience the pleasure that is inherent in solving problems chosen as one's own. Constructivism requires the change of the teacher's role from a knowledge transmitter to a coach or facilitator of student's understanding. Constructivist teachers inquire about students' understanding of concepts before sharing their own understandings of those concepts, and encourage students to engage in dialogue, both with them arid with one another. In Korea, the educational reform called open education has been spreading through out the country. There should be a paradigm shift in learning and instruction from objectivism to constructivism for better educational reform in Korea.

  • In this era that technology is replacing human labor is coming. Like the introduction of Factory Automation and Smart Factory to enhance the productivity in manufacturing works in companies, RPA (Robotic Process Automation) is being applied to strengthen the competiveness in service & office work of companies. But, RPA itself is not mature enough to be the specific technology or solution, but burgeoning as the conceptual technology alternatives to automate the business process harnessed with the concept of software robots, artificial intelligence etc. The biggest difference that the introduction of RPA can make is the transition of the work based on 'human labor', to the 'digital labor' that could result in the replacement of human labor itself with that. Considering this kind of impact to change the concept of labor, the discussion for the future policy for this is inevitable. In this paper, beginning from the overview of RPA, relevant concerns & consideration for the application of RPA will be described based on the understanding of industrial & technology trends and expected future of RPA.
