With the recent advancement of 4th Industrial Revolution technology, transportation systems are generating large amounts of mobility data related to the individual movement trajectories of vehicles and people. There are many constraints on utilizing mobility data containing personal information. Thus, in South Korea, the processing and generation of pseudonymized information and the analysis and utilization of this information have been managed in a dual manner by applying separate agencies and technologies through the revision of the Data 3 Act and the enactment of the Data Basic Act. However, this dual approach fails to securely support the entire data lifecycle and suffers from inefficiencies in terms of processing time and cost. Therefore, to compensate for the problems of the existing Expert Data Combination System and Data Safety Zone, this study proposes an Integrated Data Safety Zone Framework that integrates and unifies the process of generating, processing, analyzing, and utilizing mobility data. The integrated process for data processing was redesigned, and common requirements and core technologies were derived. The result is an architecture for a next-generation Integrated Data Safety Zone system that can manage and utilize the entire life cycle of mobility data at one stop.

Management of social infrastructure has been advanced from facility management (FM) to asset management (AM), which adopts the aggressive and proactive methods in predicting the deterioration of infrastructure, prevents failures, and eventually saves maintenance cost. Infrastructure asset management is not a simple engineering technique, but it is a new paradigm evolved from facility management practices. To implement the infrastructure asset management successfully, organizational reform is very important. This paper suggests critical success factors and key performance indicators to implement the infrastructure asset management for facility managers of government owned social infrastructures such as roads and bridges. Reorganizing the facility management group requires new vision, objectives, strategies for the paradigm-changing asset management. This paper uses Balanced Score Card (BSC) which is a proven method in measuring and setting new objectives for an organization. Once the performance indicators are reviewed repeatedly by facility managers through experts workshops, developed BSC can be used in practice. This paper discusses the development of robust BSC scoring method through in depth literature reviews and investigation of asset management practices of domestic and international cases.

The preconsolidation pressure has been commonly determined by oedometer test. However, it can also be determined by insitu test, such as piezocone test with theoretical and(or) empirical correlations. Recently, Neural Network (NN) theory was applied and some models were proposed to estimate the preconsolidation pressure or OCR. It was already found that NN model can come over the site dependency and prediction accuracy is greatly improved when compared with present theoretical and empirical models. However, since the optimization process of synaptic weights of NN model is dependent on the initial synaptic weights, NN models which are trained with different initial weights can't avoid the variability on prediction result for new database even though they have same structure and use same transfer function. In this study, Committee Neural Network (CNN) model is proposed to improve the initial weight dependency of multi-layered neural network model on the prediction of preconsolidation pressure of soft clay from piezocone test result. Prediction results of CNN model are compared with those of conventional empirical and theoretical models and multi-layered neural network model, which has the optimized structure. It was found that even though the NN model has the optimized structure for given training data set, it still has the initial weight dependency, while the proposed CNN model can improve the initial weight dependency of the NN model and provide a consistent and precise inference result than existing NN models.

This study developed a geological virtual reality-based field trip (VFT) to find an alternative to replace the actual field trip, which is often considered lightly by students owing to difficulties in the school. For this purpose, we selected a total of five geological learning sites that focus on the Mt. Jeoksang Muju-gun, Jeollabuk-do, Korea by evaluating the contents of the curriculum and the possibility of developing a VFT. The developed VFT provided middle-school students with an interactive space to observe and explore rocks and geological structures, including orbicular granite gneiss, tuff, conglomerate, sandstone, stratification, and joints. A semi-structured interview was conducted with the 1st-grade middle-school students to evaluate the educational value of the VFT. The responses of the students were analyzed using semantic network analysis to understand the significance of relationships between the reaction words. Results show that the students were able to sense reality through the VFT, which enabled them to understand and remember the characteristics of rocks. Therefore, students can indirectly have a sense of reality of an outdoor experience through the VFT program, which positively influences their learning. Our study shows that VFT can be effectively utilized as a meaningful learning resource in schools.

This study tried to establish a system of service paradigm by re-examining the Korean play culture through the people who play in the era of King Jeongjo and revealing the integration of modern service culture. The results of this study are as follows. First, King Jeongjo inspired the autonomy and creativity of the participants through the patronage of Changdeokgung Palace and led the renaissance era of Joseon as a creative play. The creative play of the service industry is reborn as a place of innovation that realizes development through a communicative intellectual network. Second, the 60th birthday Jin Chan-yeon and the aesthetics of slowness that evoke artistic play are the language of innovation that transcends language and culture. Artistic play becomes a channel of communication to share happiness with people around the world based on absolute beauty and aesthetic sensibility. Third, Jeongjo was a humanist in Joseon. This humanistic ideology leads to humanistic religion. K-service, which uses religious play as a medium, has a turning point towards healing and happiness as all participants in the service experience sacredness. There is an implication in that it pioneered a service culture by presenting a new paradigm by combining play and service, and laid the groundwork for building a unique area in global business.

The Army, Navy, and Air Force are making various efforts to develop a weapon system that incorporates the 4th industrial revolution technology so that it can be used in multi-domain operations. In order to effectively demonstrate the integrated combat power through the weapon system to which the new technology is applied, it is necessary to establish a network environment in which each weapon system can transmit and receive information smoothly. For this, it is essential to analyze the Information Exchange Requirement(IER) of each weapon system, but many IER analysis studies did not sufficiently reflect the various considerations of the actual tactical network. Therefore, this study closely analyzes the research methods and results of the existing information exchange requirements analysis studies. In IER analysis, the size of the message itself, the size of the network protocol header, the transmission/reception structure of the tactical network, the information distribution process, and the message occurrence frequency. In order to be able to use it for future IER prediction, we present a technique for calculating the information exchange requirement as a probability distribution using the Poisson distribution and the probability generating function. In order to prove the validity of this technique, the results of the probability distribution calculation using the message list and network topology samples are compared with the simulation results using Network Simulator 2.
