3D scanners are applied to many industries, such as manufacturing, construction, and shipbuilding. Recently, 3D scanner is used in 3D imaging of worksite in order to control and guide earthmoving heavy equipments, which provides basic information for intelligent excavation. This study compares the accuracy and productivity between total stations and high-resolution 3D scanners. The analysis results show that 3D scanner has high accurate rate of greater than 99 percent and has low error rate of less than 2.0mm compared to total stations. In terms of productivity, 3D scanner saves 71 percent of measuring time compared to the total station. This study confirms that 3D scanner can measure the earthwork sites with high accuracy and better productivity.

The development of multimedia devices with built-in cameras such as smart devices and various studies using video-related multimedia data such as images and video obtained from the devices have been actively conducted. These studies deal with image data. An image can be defined as a set of color information obtained from a digital sensor called a pixel. Images contain various cognitive information such as color, lighting, objects and so on. In order to extract or process such information, it is necessary to clearly understand the composition of colors. In this paper, we introduce 3-dimensional information visualization method which can effectively express the results of image processing together with color distribution. This study visualizes the characteristics of image related multimedia data as well as the characteristics of various analytical data derived from it, so that researchers can transmit the image information more clearly and effectively.

This research was started in order to recognize the necessity of systematic and scientific approach to sinkholes, and to imply from an empirical point of view that a detailed evaluation method and measure for technique should be devised. As the result drew the risk factors that cause sinkholes by reflecting the opinions of water resources and ground experts, this research is expected to contribute to the development of a more systematic and pre-preventive evaluation index by preparing a countermeasure against sinkholes. In the future, it is necessary to develop an evaluation index toward the risk factors of sinkholes, in order to establish a scientific basis and objectivity that can determine priority, by subdividing the decision-making process that is required for preparing a countermeasure against sinkholes. In addition, a detailed methodology and related technique to measure each evaluation index should be continued to be discussed, in order to review the applicability of evaluation indices on actual sites.

This study aimed to examine the association between material hardship and alcohol use among low-income households in Korea, with particular attention to whether the association was mediated by family conflict and self-esteem. Using a nationally representative sample of 960 low-income households, this study conducted a path analysis to test a structural model liking material hardship to alcohol use through family conflict and self-esteem. The significance of indirect paths was tested by a Sobel test. This study found that experiencing material hardship was directly associated with low levels of coping skills for family conflict and low levels of self-esteem, but not with alcohol use. However, material hardship was indirectly associated with alcohol use through low levels of coping skills for family conflict as well as low levels of self-esteem. The findings of this study suggest that experiencing material hardship among low-income households would be a socio-structural stressor for alcohol use, particularly in that it increases secondary role and intra-psychic strains. Implications to address material hardship and alcohol use among low-income households were discussed.
