The study was emphasized on application of the digital image processing techniques for lineament analysis. The major lineament of the study area belongs to Choogaryong faults which many geologists have studied since 1903. Also the lineament is so significant in geological views, because the lineament runs through Seoul area. The several image processing methods such as gradient, Laplacian and spatial filter have been applied, and the spatial filtering is most suitable method for lineament analysis among them. The lineaments distribute predominently in the N20.deg.-30.deg.E trend and N80.deg.-90.deg.W trend which have the conjugated relationship each other, and it coincides with the Gyeongsang conjugate system. The circular structure of study area was developed by cooling circular joint.

In recent years, the application of deep learning method to computer vision has shown to achieve great performances. Thus, many research projects have also applied deep learning technology to railroad defect detection. In this paper, we have reviewed the researches that applied computer vision based deep learning method to railroad defect detection and inspection, and have discussed the current trend and the direction of those researches. Many research projects were targeted to operate automatically without visual inspection of human and to work in real-time. Therefore, methods to speed up the computation were also investigated. The reduction of the number of learning parameters was considered important to improve computation efficiency. In addition to computation speed issue, the problem of annotation was also discussed in some research projects. To alleviate the problem of time consuming annotation, some kinds of automatic segmentation of the railroad defect or self-supervised methods have been suggested.

Network technology has been developed for very high-speed networking and multimedia data whose characteristics are the continuous and bursty transmission as well as a large amount of data. With this trend users wish to view the information about the application services as well as network devices and system hardware. However, it is rarely available for the users the information of performance or faults of the application services. Most of information is limited to the information related network devices or system hardware. Furthermore, users expect the best services without knowing the service environments in the network and there is no good way of delivering the service related problems and fault information of application services in a high speed network yet. In this paper we present a web-based application management system that we have developed for the past year. It includes a method to build an agent system that uses an existing network management standards, SNMP MIB and SNMP protocols. The user interface of the system is also developed to support visualization effects with web-based Java interface which offers a convenient way not only to access management information but also to control networked applications.

Recently, the application of BIM has been continuously expanded according to various government policies, and the application performance is being analyzed in BIM projects such as roads and railways. In line with this trend, the government is making additional efforts to introduce full-scale design BIM. The BIM design in the public sector is directly related to the estimated price. However, looking at the current status of BIM introduction, there is no support system in place for calculating the estimated price. Therefore, this study intends to analyze the priority activity that is easy to develop BIM unit price among the construction standard unit Price of construction work. In this study, in order to derive the BIM-based priority activity, BIM application statements and application guidelines were analyzed. As a result of the analysis, cast-in-place concrete construction (civil engineering) and reinforced concrete construction (architecture) were deduced as suitable construction activities for the preferential application of BIM. Since the results presented in this study are a rough analysis, it is judged that additional detailed analysis is necessary for the future.

The application of gene engineering in livestock is necessary for various reasons, such as increasing productivity and producing disease resistance and biomedicine models. Overall, gene engineering provides benefits to the agricultural and research aspects, and humans. In particular, productivity can be increased by producing livestock with enhanced growth and improved feed conversion efficiency. In addition, the application of the disease resistance models prevents the spread of infectious diseases, which reduces the need for treatment, such as the use of antibiotics; consequently, it promotes the overall health of the herd and reduces unexpected economic losses. The application of biomedicine could be a valuable tool for understanding specific livestock diseases and improving human welfare through the development and testing of new vaccines, research on human physiology, such as human metabolism or immune response, and research and development of xenotransplantation models. Gene engineering technology has been evolving, from random, time-consuming, and laborious methods to specific, time-saving, convenient, and stable methods. This paper reviews the overall trend of genetic engineering technologies development and their application for efficient production of genetically engineered livestock, and provides examples of technologies approved by the United States (US) Food and Drug Administration (FDA) for application in humans.

With greater utilization of web application and growth of its market, the function of such application is being expanded With today's increasing demand for high quality software, we see a sharp rise in the interest for web application test. The current trend is that web applications are being developed based on a framework of developmental environment. Hence, as the scope of that framework expands, each module of the entire web application is being configured by the combination of heterogeneous files. The distinctive characteristics of a web application are based on the fact that the framework that is provided in partially completed form controls the structure of all objects of development. The present study defines the web business logic as a minimal unit which has meaning as a unit of application for the web application. In this paper, we define web business logic as a least meaningful execution unit of web applications, propose how to generate automatically the BizUnit test code for it, and analyze the effectiveness of testing of the web application via the BizUnit test codes.
