  • Subsurface Investigation results always reflect a level of soil uncertainty, which sometimes requires statistical corrections of the data for the appropriate engineering decision. This study suggests a closed-form framework to extract the outlying data points from the testing results using the statistical geo-spatial information analyses with outlier analysis and kring-based crossvalidation. The suggested analysis method is conducted to soil stratification using the borehole data in Yeouido.

  • A prototype design process visualization and guidance system, is being developed. Its purpose is to visualize the design process in more intuitive manner so that one can get an insight to the complicated aspects of the design process. By providing a tangible utility to the design process performed by the expert designers or guided by the system, novice designers will be greatly helped to learn how to approach a certain class of design. Not only as an analysis tool to represent the characteristics of the design process, the system will be useful also for learning design process. A design ontology is being developed to provide the system with a knowledge-base, representing designer's activities associated with various design information during the conceptual design process, and then to be utilized for a computer environment for design analysis and guidance. To develop the design ontology, a conceptual framework of design activity model is proposed, and then the model has been tested and elaborated through investigating the nature of the early conceptual design. A design process representation model is conceptualized based on the ontology, and reflected into the development of the system. This paper presents the development process of the visualization system, modeling of design process ontology, and how the system could be utilized for the analysis and learning of conceptual design methods using computer mediated design support environment.

  • In this paper, we aim to propose a comprehensive framework for cyber threat analysis of urban air mobility (UAM) or advanced air mobility (AAM) communications, navigation, surveillance, and information system infrastructure. By examining potential vulnerabilities and threat vectors, we seek to enhance the security and resilience of UAM infrastructure. We conduct a detailed cyber threat analysis to identify and categorize various types of cyber threats, assess their impact on the CNSi systems, and evaluate the vulnerabilities within these systems that may be exploited by such threats. This analysis will provide valuable insights for stakeholders involved in the deployment and operation of UAM systems, ultimately contributing to the safe and efficient integration of urban air transportation.

  • The growing number of threats to society through the uncontrolled distribution of information is forcing library communities in many countries to reconsider their views on free access to collections. Based on the content of numerous documents of international importance, it can be concluded that in any democratic country access to information is one of the most important human rights, along with the right to life, liberty, and security of person. However, the state has the right to restrict citizens' access to information within the framework of existing legislation. Constantly, restrictions on access to information are established in order to protect the ethical foundations of the constitutional order, morality, health, rights, and legitimate interests of others, to ensure the country's defense and state security. It goes without saying that each country has the right to independently decide where the boundaries lie between permitted and prohibited information, including printed information, contained in library collections. This article describes three levels of access restriction: foreign, state, and regional. The authors have analyzed the legal and regulatory documents that govern libraries, as well as the reasons and methods of limitation. A comparative analysis of the restriction of access to information in the countries of Europe and Asia is presented.

  • This study suggests an effective online guide for foreign teachers who want to teach English in Korean schools. When designing this guide for overseas applicants, there should be a consistent analysis to reflect the process of the system. Thus, this paper provides an analysis and results for an integrated online guide to increase the efficiency based on the pedagogical framework for analysis of the 'ADDIE' model (Analyze, Design, Development, Implementation, and Evaluation). The number of job applicants who wish to teach English in Korea is growing rapidly because Korea is one of the fastest growing economies in the world and the 'Korean Wave' has especially been experiencing significant changes with the development of social network services and digital technologies. As a result, overseas applicants' expectations regarding Korea when they are seeking information and applying is very high, but the aspects of the procedure provided by the government are somewhat disappointing. The paper presents customer needs and specific recommendation for each step of the application process to improve the guide's effectiveness.

  • It can be important framework data to monitor the change of land-use pattern of river boundary in design and management of river. This study analyzed the change of land-use pattern of Gab- and Yudeung River using time-series aerial images. To do this, we carried out radiation and geometric correction of image, and estimated land-use changes in inland and floodplain. As the analysis of inland, the ratio of residential, commercial, industrial, educational and public area, that is urbanized element, increases, but that of agricultural area shows a decline on the basis of 1990. Also, Minimum Distance Method, which is a kind of supervised classification method, is applied to extract water-body and sand bar layer in floodplain. As the analysis of land-use, the ratio of level-upped riverside land and water-body increases, but that of sand bar decreases. These time-series land use information can be important decision making data to evaluate the urbanization of river boundary, and especially it gives us goodness in river development project such as the composition of ecological habitat.

  • Main starting valve is one of the main parts in the control system of diesel engines, purposed for starting main engines. It is composed of ball valve, check valve, actuator, etc. The design axioms provide a general framework for design methodology. Two axioms are independence axiom and information axiom. These axioms can be applied to all design process in a general way. The first axiom is introduced to analyze and evaluate the design of a main starting valve. The design parameters(DPS) are determined sequentially by considering the independence axiom. For the structural design of a main starting valve, the strength is calculated by using finite element method. In addition, the strength of its actuator piston is evaluated.
