Unmanned Aerial Vehicle (UAV) platform is being widely used in disaster monitoring and smart city, having the advantage of being able to quickly acquire images in small areas at a low cost. Ground Control Points (GCPs) for positioning UAV images are essential to acquire cm-level accuracy when producing UAV-based orthoimages and Digital Surface Model (DSM). However, the on-site acquisition of GCPs takes considerable manpower and time. This research aims to provide an efficient and accurate way to replace the on-site GNSS surveying with three different sources of geospatial data. The three geospatial data used in this study is as follows; 1) 25 cm aerial orthoimages, and Digital Elevation Model (DEM) based on 1:1000 digital topographic map, 2) point cloud data acquired by Mobile Mapping System (MMS), and 3) hybrid point cloud data created by merging MMS data with UAV data. For each dataset a three-dimensional positional accuracy analysis of UAV-based orthoimage and DSM was performed by comparing differences in three-dimensional coordinates of independent check point obtained with those of the RTK-GNSS survey. The result shows the third case, in which MMS data and UAV data combined, to be the most accurate, showing an RMSE accuracy of 8.9 cm in horizontal and 24.5 cm in vertical, respectively. In addition, it has been shown that the distribution of geospatial GCPs has more sensitive on the vertical accuracy than on horizontal accuracy.

지난 93년 11월 현대건설에서 국내 건설업체 최초로 ISO 9000 품질시스템 인증서를 취득한 후 많은 건설업체에서 인증서를 취득했거나 추진중에 있다. 국내 건설업계의 ISO 9000 인증업무를 3~4개의 외국 인증기관에서 점유하고 있어서 건설사마다 비슷비슷한 시스템으로 가고 있는 것이 현실이다. 그러나 인증기관마다 장단점이 있으므로 각 회사는 좀더 여러 인증기관에서 다양하게 선택하는 것이 나으리라고 본다.

This research examines how influential the certificate is on career development and job satisfaction. The outcome of substantial analysis on hypothesis of the study is: First, three factors-proactiveness, value, competitiveness are the positive effect on motivation for certificate. However, it is shown that the correlation and regulation factors do not have a significant effect on career development. Second, career development has a positive relation with the job satisfaction. Third, value and association among motivation factors for certificate acquisition have a positive effect on job satisfaction. However, it is revealed that proactiveness, competitiveness, and bylaw factors do not have significant influences on job satisfaction. These outcomes prove that private certificates do not meet the need realistically in the business field. It is caused by the low level of difficulty of the certificate exam, which results in the standardization state where it becomes easier for anyone to obtain the certificate. In order to resolve the problem in relation to the private certificate acquisition, it is suggested that advices of field experts should be actively reflected on the exam and that the difficulty of the exam should be moderated to acquire comparability and to reflect reality.

It has been two years since the national certificate of Arts & Culture Education Instructor(ACEI) was implemented the 2012 amendment to the Arts & Culture Education Act. Separate from the initial policy goals, students who attend the program to achieve ACEI certificate share various expectations, motivations and intents. The purpose of the research is to understand the collective identity of future ACEIs to evaluate the initial policy implementation during the period when the collective professional identity has not been fully formed yet. This research studies the data that were collected from 172 students who were attending one of the official ACEI institutes in Seoul area. As one of qualitative research methods, Questionnaire Method was employed to conduct this phenomenological study. James E Marcia's theory provides the theoretical framework for the data analysis of this study. The research results indicate that many students'identity status are between Identity Diffusion and Moratorium, which raises concerns for both arts and cultural fields as well as the policy success. Therefore, this research will relate these findings to the larger arts and culture infrastructure in order to better prepare them as arts and cultural professionals and also to stress the importance of the job market development and social environment that can accept them.

This paper proposes a method to acquire image data inside tunnel structures and a method to structure the acquired image data. By improving the conditions by which image data are acquired inside the tunnel structure, high-quality image data can be obtained from area type tunnel scanning. To improve the data acquisition conditions, a longitudinal rail of the tunnel can be installed on the tunnel ceiling, and image data of the entire tunnel structure can be acquired by moving the installed rail. This study identified 0.5 mm cracked simulation lines under a distance condition of 20 m at resolutions of 3,840 × 2,160 and 720 × 480 pixels. In addition, the proposed image-data-structuring method could acquire image data in image tile units. Here, the image data of the tunnel can be structured by substituting the application factors (resolution of the acquired image and the tunnel size) into a relationship equation. In an experiment, the image data of a tunnel with a length of 1,000 m and a width of 20 m were obtained with a minimum overlap rate of 0.02% to 8.36% depending on resolution and precision, and the size of the local coordinate system was found to be (14 × 15) to (36 × 34) pixels.
