As the Western technologies have been introduced to our culture since the modern age. We have uncritically accepted Japanese style terminology for new things without reflection on the relations of concept, language and fact. Concept is the basis of human thinking and also a criterion of distinguishing what we see and hear. Thus, establishment of concept and naming are important once new technologies or objects are created. In the study, we will take automobile terminology which is relatively familiar to us for example in order to explain the importance of naming. We will reflect our reality where the Japanese style terminology and English style terminology for the automobile components and structures are mixed up and urge the need of establishing the easier terminology. Reorganizing the terminology is also important but automotive engineers and linguists need to work together on ways to translate the terminology into easier ones for common people.

In Soil Taxonomy system, anthropogenic soils are still classified as Entisols since the International Classification Committee for Anthropogenic Soils is in the process of classifying anthropogenic soils as new orders. In reality, it is difficult to characterize anthropogenic soils because Soil Taxonomy (ST) system does not distinguish between natural and anthropogenic Entisols. On the other hand, World Reference Base for soil resources (WRB) considers human impacts on soils and contains an independent category of anthropogenic soils, which makes easier to understand anthropogenic soil characteristics than Soil Taxonomy system. A remodeled paddy field (Gasan) was selected to classify by ST and WRB. Soil samples were taken to analyze chemical and physical properties. Based on the results of the analyses, the ST system classified Gasan as coarse loamy, mixed, mesic, Aquic Udorthents while the WRB did as Stagnic Urbic Technosols (Oxyaquic, Arenic). As a conclusion, the WRB classification information of the anthropogenic provides more detail characteristics of the anthropogenic soils.

The following thesis has been composed with the inspiration attained from Paul Ardenne's conception on Contextual Art. In Europe and in the United States, there is a group of artists who emphasize in the importance of artist's participation in social, political, economical, environmental and moral issues. Since the 1960's, these artists have pondered on Modernism's ideas where art is contextually separated from humanly issues whereas the manners of such artists put on emphasis in the intent to participate in the real human social and ethical issues. Forerunner in this field of art such as Wolfgang Leib display hybrid or meta style in their work. His work displays a quadrilateral form of pollen which represents the simultaneous blending of two mixed ideas such as the abstract from the real. Thus heterogeneous style and philosophy which includes a range of medias and today's trend is observed in Contextual Art. Such art form is also found in landscapes where it is not seen as an observable object but rather an interactive object. It is correlated to Arte Povera of the Italian Art Movement, Support-Surface of the French Art Movement and lastly to the Fluxus. Through these art movements, we find a mutual antipathy towards putting art for sales in the capitalism market and reflect the social role of art in postmodern era.

Recently, interest in eco-friendly structure has been increased and many researches about hwang-toh are being actively processed. However, most researches are about material properties of hwang-toh, and researches about structural performance are insufficient. Moreover, the usability of activated hwang-toh is being identified in some ways, but its use rate is low in economic aspect in reality. Non-activated hwang-toh is expected to be advantageous in respect of economy but its material and structural performance have not been identified. Therefore, the effect of activated hwang-toh and non-activated hwang-toh on flexural capacity of hwang-toh concrete beam is analyzed in this research.

As production cycle has become more and more shorter, the demand of rapid prototyping technology has increased largely. There are many methods for rapid prototyping technology, such as SLA. SLS, FDM. INK JET, LOM and so on. Of all methods, SLA has been most widely used for fabricating precision parts. But products manufactured by this method have limitation of single color and single material. So the principal purpose of this study is to overcome the limit of single color product. If the internal structure of manufactured product is visible with multi-color characteristic, it is possible to check easily the designed model with reality. In order to give multi-color characteristic to the product, photocurable resin mixed with pigment is used in this study. First, transparency of photocurable resin without pigment is evaluated, and then color characteristic and curing characteristic of the mixture is evaluated changing mixing ratio. Through the basic experiments, it becomes possible to fabricate multi-color 3D prototype without assembly.

The curve of motion indicated to waveform of the fast movement of human extracted using virtual reality or the quantity of time fluctuation of the electromagnetic signal as the quantity of electric fluctuation of the atmosphere is complex. It is important to decide exactly the signal property as the inflection point for the observation signal. When the signal is mixed by noise signal, the traditional method is difficult to detect the inflection point. In this paper the noisy signal is eliminated by wavelet thresholding method and the filter using natural observation theorem is applied. It shows that the inflection point of the signal waveform can be detected exactly.

This study was a quasi-experimental study with a single group pre-posttest design for evaluating the effects and meanings of a global health training program for nursing students. A mixed data collection method utilizing both qualitative and quantitative methods was applied. The qualitative method consisted of reflection journal entry analysis, while the quantitative study evaluated data collected from a self-reported questionnaire. After attending the program, cultural competencies of participants significantly increased than pre-test while global citizenship was not. Through an analysis of reflection journals written during the overseas training period, the meanings of experiences derived after the program were classified into five themes and 12 sub themes, which were, 'improvement of global health leadership', 'experience of barriers in reality', 'improvement of nursing professional value', 'inspiration of a perspective on health equity', and 'internal growth'. The results indicate that global health training program evaluated in this study was meaningful; it provided students with opportunities to experience the nurse's role in diverse global environments and attempted to measure the effects.

The drone technology, which is receiving a lot of attention due to the 4th industrial revolution, requires an Unmanned Aerial Vehicles'(UAVs) flight path search algorithm for automatic operation and driver assistance. Various studies related to flight path prediction and recommendation algorithms are being actively conducted, and many studies using the A-Star algorithm are typically performed. In this paper, we propose an Optimal 3D Flight Path Recommendation System for unmanned aerial vehicles. The proposed system was implemented and simulated in Unity 3D, and by indicating the meaning of the route using three different colors, such as planned route, the recommended route, and the current route were compared each other. And obstacle response experiments were conducted to cope with bad weather. It is expected that the proposed system will provide an improved user experience compared to the existing system through accurate and real-time adaptive path prediction in a 3D mixed reality environment.

Among the technologies of the 4th industrial revolution, drones that have grown rapidly and are being used in various industries can be operated by the pilot directly or can be operated automatically through programming. In order to be controlled by a pilot or to operate automatically, it is essential to predict and analyze the optimal path for the drone to move without obstacles. In this paper, after securing and analyzing the pilot training dataset through the unmanned aerial vehicle piloting training platform designed through prior research, the profile of the dataset that should be preceded to search and derive the optimal route of the unmanned aerial vehicle was designed. The drone pilot training data includes the speed, movement distance, and angle of the drone, and the data set is visualized to unify the properties showing the same pattern into one and preprocess the properties showing the outliers. It is expected that the proposed big data-based profile can be used to predict and analyze the optimal movement path of an unmanned aerial vehicle.
