  • Mapping systems using Satellite Imagery has not been well-established compare to conventional Arial Photograph mapping systems. In order for satellite imagery to produce a stable quality of maps, it requires to follow the standard mapping procedures. In this satellite imagery study, we proposed four methods of mapping procedures. Mapping methods were established by generating trial maps and analyzing types of input data and functions of DPW (Digital Photogrammetric Workstation). On quantitative aspect, accuracy of each steps were measured by increasing 2 GCPs each time from the minimum of 6 GCPs. In DLT, with the minimum of 10 points, RMSE is 2 pixels at most. Besides that, interpretation and stereoscopic plotting using KOMPSAT-1 imagery and other simulated imagery was performed. The tests resulted that, for KOMPSAT-1 (6.6m) stereoscopic images, the possibility of interpretation is 44.79% and possibility of stereoscopic plotting is 43.75%. In the other hand, for simulated imagery (1m), the possibility of interpretation is 60.92% and possibility of stereoscopic plotting is 55.18%.

  • In this paper, we propose a technique to analyze similarity between SQL queries and to assist integrating similar tables. First, the table information was extracted from the SQL queries through the query structure analyzer, and the similarity between the tables was measured using the Jacquard index technique. Then, similar table clusters are generated through hierarchical cluster analysis method and the co-occurence probability of the table used in the query is calculated. The possibility of integrating similar tables is classified by using the possibility of co-occurence of similarity table and table, and classifying them into an integrable cluster, a cluster requiring expert review, and a cluster with low integration possibility. This technique analyzes the SQL query in practice and analyse the possibility of table integration independent of the existing business, so that the existing schema can be effectively reconstructed without interruption of work or additional cost.

  • This study was on leaching test(KSLT, TCLP) of the aggregate for the products(RA-1) and for the site(RA-2) to evaluate the characteristics of contaminants and the possibility of contamination arising from the aggregate. On the basis pH, conductivity and heavy metal contents in the aggregate, RA-1 indicated higher than RA-2. As a result of the leaching test, the pollutants were eluted from the aggregate increased as the particle size of the aggregate was smaller. The pH in the aggregate had a strong alkali by a pH value of 9.0~12.3, the conductivity was higher in less than 10mm RA-1 due to the leaching of dissolved inorganic ions. The heavy metals satisfied the leaching standards of KSLT and less 10% was eluted from the aggregate. As a result of evaluating water pollution possibility of the aggregate, the pH displayed in items with a very high possibility of contamination, conductivity and turbidity did in item with a low possibility of contamination and on the other hand the heavy metals did in item with a very low possibility of contamination.

  • The purpose of this study was to provide basic materials on establishing convergence oriented respiratory infection management system in nursing students attending clinical training by analyzing anxiety, knowledge, possibility of infection, possibility of prevention, and compliance level of preventive behavior. Data were collected from 222 nursing students experienced clinical practice from June 15th to 30th in 2015 using questionnaire. Characteristics relative to variables were measured, and analyzed using SPSS 18.0 program. The results are as follows. The anxiety was 42.70(max 80 points), but possibility of infection was 22.55(max 100 points). Also, knowledge(11.73 out of 16 points), possibility of prevention(7.37 out of 10 points), and compliance level of preventive behavior(34.55 out of maximum 48 points) were slightly above average. The influencing factors on compliance of preventive behavior were anxiety and possibility of prevention. It is needed to lead convergence oriented approach on enhancing compliance of preventive behavior through providing information and educating possibility of prevention during MERS outbreak.

  • We reported researches of possibility of the usage of known electrooptical effects (EOE) for diffractive displays (DLCD). We found different EOEs provide the possibility of broad selection of steepness of volt-contrast characteristics at rather large steep of modulation without the usage polarizes. The data are represented much promising for broad development DLCDs.

  • The purpose of this study was to examine the effect of the possibility of job-related risk, emotional labor, and emotional leadership on the job turnover intention of caregivers working at the long-term care facilities in Korea. For the study, survey data of 434 caregivers at senior nursing homes were collected and analyzed using hierarchical multiple regression method. The results showed that high level of caregivers'perception of both the possibility of management risk and employee risk led to increased turnover intention. On the other hand, perception of the possibility of social-disaster risk did not give significant impact on turnover intention. Although the perception of the possibility of service user risk gave statistically significant effect on the turnover intention, the direction was the opposite to the one set at the research hypothesis. Frequent camouflage behavior("surface acting") of caregivers, which is the kind of emotional labor led to increased turnover intention. However, caregivers'behavior consistent with their inner warm heart("deep acting") did not lead to a statistically significant result. Lastly, the more caregivers perceive their superiors'emotionally supportive leadership, the lower possibility of turnover intention. Based on the above result, the researchers suggested several intervention methods in order to prevent turnover of caregivers and improve service quality of long-term care institutions.

  • The electric railway cars are operated by high voltage supply through the catenary wire. Also, numerous electric equipments operated by electric signal are distributed in the electric railway cars. Such electric equipments are exposed to EMI/EMC problems, and there is the possibility that the magnetic field due to the catenary wire current takes effect on the electromagnetic field in the electric railway cars which move under the catenary wire. There is the possibility that the electromagnetic interference generates in view of the operation of many electric equipments in the electric railway cars. There is the possibility that the communication device faults generate, and that the hazards on the human beings generate. In this paper, we predict the magnetic field around the catenary wire, and obtain the exact magnetic field distribution by comparing the analytic results and the numerical results. Finally, we confirmed the possibility of the passive loop mitigation by comparing the analytic results and the numerical results through the passive loop mitigation technique.

  • This study explored the effects of after-school services on whether they reduced the possibility of self-care of children. In terms of characteristics of the use of after-school services, it focused on the 1) types, 2) diversity, and 3) use patterns of the after-school services. For the analysis, it used data of the cohort of elementary-school children from the Korean Children and Youth Panel Survey. The main findings are as follows. First, private mentoring and after-school services provided by welfare centers reduced the possibility of self-care. Second, when the total amount of educational time was controlled, the diversity of participating after-school services did not explain the possibility of self-care. Third, when the total amount of educational time was controlled, the use patterns of after-school services did not explain the possibility of self-care. Based on these findings, it suggested policy implications and future research.
