This research proposes the method of using the Convolutional Neural Network (CNN) more efficiently in the classification of architectural images. The characteristics of images are not considered in the conventional methods of classifying architectural images. In this research, architectural images are first categorized primarily as two-dimensional images such as facades or three-dimensional images such as perspectives before classifying the types of the images. We compared the cases, where the types of architectural images are classified without being categorized as two- or three-dimensional images, with the cases where they are classified after the preliminary categorization is conducted. In this research, it was confirmed that the latter had higher classification accuracy. This implies that for image classification using the CNN, it could be effective to classify the types of architectural images after categorizing the basic preliminary delimitation based on characteristics of the images. We anticipate that the outcome of this research for architectural images will also apply to classification of other types of images.

Domestic petrochemical-based industries in order to prevent major industrial accidents since 1996, introduced the PSM(Process Safety Management) system, KOSHA (Korea Occupational Safety and Health Agency) divided into P, S, M+, M- grade through the validation and verification grade and then Ministry of Employment and Labor has been checking the implementation status of PSM workplace. According to the national audit submissions, P, S grade workplace accounted 19 of 27 dead(70%) over the last three years major industrial accidents. Regard of this study is the main basis of comparison, the analysis of the PSM system and relevant summary of the issue through the opinions of site engineer with a detailed review of the existing research results, management plan attempts to organize and comparison with similar off-site consequence analysis and risk management plan to compare the differences and features. For an in-depth investigation to conduct a survey and interview survey of experts, including representatives of the PSM consulting agency find out the problems of the PSM system, we propose a reasonable improvement method for effective PSM system.
