  • This article is the second one of the continuous study that considering 'body' as important and researching bodies as 'literature-media': the phenomena and functions. The present writer first of all have paid attention to the study of the contrast between pansori and ballet to secure definite, historic and theoretical prospect of this continuous study. In the process, the Korean creative ballets based on Korean classic narratives were illuminated as the glocal culture contents. And then the necessity of citing Korean characteristic rhythm and tune was insisted to acquire the true individuality and identity(What is the reason Chunhyang dances?(I)). The solution is jangdan and chang of pansori. This article aimed the supplementation of detailed and actual arguments to strengthen and formulate the opinion. And then this article desired to estimate the way to improvement of Korean creative ballet by properly citing jangdan and chang with the actual application cases of Korean ballets. Until now, at least pansori have gotten a sort of visual effectiveness: simply be seen and heard as unusual constituent. Thus the necessity of pansori to work motions and choreography beyond the simple usages. Also the way to be extended generally through being refined by the partial applications.

  • This study deals with Turbo-Roundabout of Special-Roundabouts. Recently, many rotary intersections are being constructed in Korea, but the effect of the rotary intersection depends on the total entrance traffic volume and the area of the paper. The purpose of this study is to analyze the operation and accident reduction effect of turning traffic signal intersection with small traffic volume into turbo - type turning intersection. The main results are as follows. First, when the traffic volume of the main road is high, the traffic volume of the subway is less than 10 ~ 15%, or when the left turn ratio is less than 30%, it is improved when switching to the turbo type turn intersection instead of the first turn type and second turn type turn intersection Was analyzed. Second, it is considered that turbo type rotary intersection is more effective than first - type rotary intersection, and it is more effective in increasing road capacity because the area of paper is smaller than that of second - order rotary intersection. Third, the number of traffic accidents decreased by 45.9% and the number of injured persons decreased by 76.5% after the conversion of the turnover type turnover to turbo type. 100%), the number of car accidents was 0.3, and the number of casualties was 0 (100%). Finally, the positive evaluation of the user satisfaction survey showed that the improvement in safety, accessibility, and convenience was improved by 60.4%, which was improved by 16.4% to 76.8% after the conversion to the turbo type turnover.

  • This paper describes the performance improvement of Software (SW) digital filter using GPU (Graphical Processing Unit). The previous developed SW digital filter has a problem that it operates on a CPU (Central Processing Unit) basis and has a slow speed. The GPU was introduced to filter the data of the EAVN (East Asian VLBI Network) observation to improve the operation speed and to process data with other stations through filtering, respectively. In order to enhance the computational speed of the SW digital filter, NVIDIA Titan V GPU board with built-in Tensor Core is used. The processing speed of about 0.78 (1Gbps, 16MHz BW, 16-IF) and 1.1 (2Gbps, 32MHz BW, 16-IF) times for the observing time was achieved by filtering the 95 second observation data of 2 Gbps (512 MHz BW, 1-IF), respectively. In addition, 2Gbps data is digitally filtered for the 1 and 2Gbps simultaneously observed with KVN (Korean VLBI Network), and compared with the 1Gbps, we obtained similar values such as cross power spectrum, phase, and SNR (Signal to Noise Ratio). As a result, the effectiveness of developed SW digital filter using GPU in this research was confirmed for utilizing the data processing and analysis. In the future, it is expected that the observation data will be able to be filtered in real time when the distributed processing optimization of source code for using multiple GPU boards.

  • This paper studies the contribution of imports and inward foreign direct investment (FDI) as a vehicle of technology transfer onto the EU new member states at both macroeconomic and industry level. The paper takes the effectiveness of the recipient's utilization into account by constructing a new index, the so-called Effective Absorption (EA) Index, to measure ability to absorb and utilize the foreign technology in the recipient country. Using data from 12 donors and 10 recipients from 1998 to 2009, the study at macroeconomic level indicates that technical spillovers of foreign research and development (R&D) play more crucial role relatively to domestic R&D on total factor productivity (TFP) growth of the new member states. Imports are found as the major vehicle of technical spillovers rather than inward FDI. The study at industry level is conducted by using data from 17 manufacturing industries of 10 donors and 6 recipients during 1998 to 2009. The empirical results also support the findings at country level. The patterns of technology transfer are different across industries. Nonetheless, technical spillovers exhibit significantly high contribution on TFP growth in high-tech manufacturing industries.

  • Various studies have been conducted to analyze the location appropriateness and capacity of shelters. However, research on how to select new shelters is relatively insufficient. Since the shelter is designated in case of emergency, it is also necessary to efficiently select the location of the shelter. Therefore, this study presented a method for selecting the location of the shelter using network analysis that has been used to analyze the location appropriateness of shelters and genetic algorithm which is a representative heuristic algorithm. First, the network analysis using the existing civil defense evacuation facility data was performed and the result showed that the vulnerability of evacuation has a high deviation by region in the study area. In order to minimize the evacuation vulnerable area, the genetic algorithm was designed then the location of new shelters was determined. The initial solution consisting of candidate locations of new shelters was randomly generated and the optimal solution was found through the process of selection, crossover, and mutation. As a result of the experiment, the area with a high percentage of the evacuation vulnerable areas was prioritized and the effectiveness of the proposed method could be confirmed. The results of this study is expected to contribute to the positioning of new shelters and the establishment of an efficient evacuation plan in the future.

  • The purpose of this study is to develop a survey tool of scientific character for elementary student which connects science education and character education effectively by figuring out traits of elementary students' character being presented in teaching and learning context of elementary school science. For this, we adapted the theocratical model from the previous research which defined scientific character as the competencies being able to practice in concrete teaching and learning context of science. Based on this model, we developed the survey tool as 'Scientific Character Inventory for Elementary Student' to assess elementary students' scientific character as the competences to practice the virtues being pursued in the context of elementary school science and verified its reliability and validity. As a result of an exploratory and confirmatory factor analysis, we confirmed all the items could be summarized into 28 items and eight constructs such as scientific problem-solving, self-management, self-reflection, communication, interpersonal skill, community participation, global citizenship, and environmental ethics awareness. We found that minimum reliability coefficient of constructs was over than 0.5 and reliability coefficient of the total items was 0.878. And also, there was modest relationship between each construct and the total score of scientific character. These results show that the developed survey tool can be useful in evaluating the effectiveness of science character education. This study is meaningful in that it systematically reveals constructs of scientific character which can be raised in concrete context of science teaching and learning so as to suggest the survey tool to assess this.

  • This study investigated electrical conductivity, electromagnetic shielding effectiveness, and mechanical property to improve electromagnetic shielding performance of high performance fiber reinforced cementitious composites (HPFRCC). Steel fiber, steel slag and carbon black as a conductive material were incorporated into the HPFRCC mixes. In addition, 2% CNT solution which was produced by dispersing multi-wall carbon nanotube (MWCNT) into water was used as a conductive material. In the test results, electrical conductivity of HPFRCC specimens was very low except for the specimen incorporating 1% carbon black. Micro structure of cement matrix was changed as the curing time increased, which negatively affected the conductive network of HPFRCC. In case of HC1 specimen showing a conductive network (0.083 S/cm), the electrical conductivity of the specimen after being dried at $60^{\circ}C$ for 72 hours to exclude the effect of water on electrical conductivity was significantly reduced to 0.0003 S/cm. The most important parameter of electromagnetic shielding effect was found to be a steel fiber while the effect of carbon black and steel slag was very few. The correlation between electrical conductivity and electromagnetic shielding effect does not seem to be clear.

  • As smart education increases the demand for new teaching-learning methods, teacher training colleges need to systematize smart education teaching-learning methods for pre-service teachers. This study designed a smart education teaching-learning model, which is applicable to pre-service teachers, by analyzing the smart education teaching-learning types for primary and secondary schools at national and international levels and by analyzing the Creation Teaching Learning Assessment (CTLA) model. The goal of smart education is to reinforce capability of learners. The smart education teaching-learning model designed to help pre-service teachers reinforce their smart literacy is suitable for reinforcing capability of future learners to receive smart education. The smart education teaching-learning model in this study was designed as a 15-week teaching plan applicable to pre-service teachers at teacher training colleges. In the teaching-learning model, problem-based learning (PBL), a situated learning model, and cooperative learning model were applied to weekly instructions. Further research should be conducted to prove its effectiveness in allowing pre-service teachers to reinforce their smart literacy by making gradual improvement in this model and to develop and test smart education teaching-learning models constantly.
