Due to the coronavirus pandemic and diplomatic disputes, governments are actively developing a policy to revitalize·reshore manufacturing and to diversify international cooperations. In order to develop such a policy, it is very important to compare and analyze domestic·international geospatial information. Over the decade, the US·EC governments have conducted a series of national researches to build data-based tools that can monitor·analyze regional geospatial information driven by government R&D investments. In the case of the EC system, it can compare geospatial information in domestic and international(including Korea) regions. Compared to US·EC cases, Korean examples of national researches with available data analplatform need future improvements. Current study is investigating an automated analysis methodologies using "National Institute of Science and Technology Information (NTIS)" DB, which was national security data until recently. Research on data-mining regional geospatial information can contribute to support policy fields that need to discover new issues in response to unexpected social problems such as recently faced corona and trade disputes.

The objectives of this study are to investigate core learning ability necessary for the 21st century and to develop core human resources required for social and national development in the future. The '21st Century Learning Ability Project' is to approach the existing knowledge and learning multidisciplinary and interactively based on the learning ability of each learner and individually and socially valuable themes. Even in Korea, a variety of intersubject integrative educational curriculum was attempted to cultivate learning ability. However, there are not enough teachers who can teach the differences between the content and characteristics for each subject by fully understanding them. Thus, it is difficult to apply them easily to the field of education. Thus, this study develops the multidisciplinary customized educational curriculum in order to develop the learning ability necessary for the 21st century, analyzes the reality of the educational curriculum integrating the academic knowledge in order to support this effectively. As a result, this study offers the interdisciplinary customized integrated model applicable to elementary and middle schools.

This study started with the question of whether the museum oral history recording projects, which have been increasing steadily in recent years, are being used in various forms, especially in exhibitions. This paper is emphasized on the need for the oral history-related projects to lead to various museum activities including exhibitions and educations and so on. As a practical example of this, to explore the future directions and tasks for oral history projects in museums 'A Research Project of Producing Oral History Video Clips for the Exhibition of IMF Financial Crisis Situations' of National Museum of Korean Contemporary History is analyzed. This research argues that oral history functions as an exhibition representation device that more actively reveal the reality of a specific historical event. Therefore, this study suggests that the museum can be developed as a venue for various discourses in which citizens participate actively using oral history.

본 논문에서는 공사현장 작업자의 실질적 영향을 미치는 요소들을 고려하여 인공지능기반의 실시간 위험성 추정 기법을 개발하였다. 기존 재난안전학 또는 안전공학에서는 위험성평가를 실시하여 강도·빈도에 의하여 위험성을 추정하고 도출된 값을 통해 위험한 정도를 분류하는 경우가 많다. 그러나 대부분의 공사현장에서는 정적인 위험성평가를 통해 해당 유해위험요인을 근거로 형식적인 위험성평가가 이루어지고 있기 때문에 대부분의 사고 후 증빙 자료로만 활용되고 있는 것이 현실이다. 이 위험성평가를 진행하면서 변화하는 환경의 유해위험을 실시간으로 반영할 수 없게 되고, 이는 실질적인 작업자의 안전을 보장해 주지 못하는 문제를 발생시킨다. 이러한 점에서 위험성평가와 더불어 실질적인 안전한 작업장을 만들기 위해서 작업자의 건강정보 및 실시간 공사현장의 영상정보에 기반한 위험성 추정 기법은 실질적 안전사고를 예방하는 방법론 중 하나가 될 수 있다. 작업자의 건강정보는 개개인 맞춤형 건강 데이터에 근거한 해석이 가능하고 실시간 공사현장 영상은 작업 중 발생할 수 있는 돌발상황에 대비하기위해 사용된다. 이러한 위험성 추정 방법은 다양한 공사현장의 위험성 추정 기법으로 사용될 수 있다. 이로 인해 높은 정확도의 위험성 추정 수치를 얻을 수 있으며, 이는 실질적안 안전 예방활동에 있어서 매우 중요하게 작용한다. 위험성 추정 수치 예제를 통하여 본 논문에서 제시된 위험성 추정 방법론이 타당함을 확인하였다. 본 논문에는 기존 위험성평가에 더해 작업자의 건강정보 및 공사현장 실시간 영상정보를 이용하여 실질적인 작업자 안전을 위한 예방 방법을 제시하였다.

This study is the basic research to develop the customized base module for modular road system. A case study was carried out on designs of base module for soft soil condition. Two types of base module was proposed; crossbeam module and crossbeam-pile module. Based on the case study, it was verified crossbeam-pile module is suitable for soft soil condition and the optimum dimension of crossbeam-pile module for modular road system constructed on soft soil was determined. For development of the optimal base modular for modular road system, it is needed in the future to build a data base about ground and roadbed of road construction sites and to classify and systemized base modules according to soil conditions through many case studies.

This study was carried out to develop Tablet PC based customizing system for fine mapping of forest cover type. The major contents and characteristics of FIS developed in this study were as follows. Field Investigation System (FIS) has a merit of accessibility to display exact location in various spatial data with position information received from the GPS. FIS can be used to record and manage many field information on which field investigation is done, with the help of the memo tool, field-sheet tool, calculating distance and area with measuring tool as well as editing forest type. It is possible to do field investigation effectively using FIS developed in this study. Accordingly, investigation and time costs can be reduced and field-work productivity will be improved.

The construction industry's fatality count stands at 402, comprising approximately 46% of total industrial accidents. Notably, construction costs less than 5 billion won account for about 69%, so strengthening safety management at small and medium-sized construction sites is required. In this study, 19,511 accident investigation data were collected using web scraping. Through statistical analysis of the collected structured data and text mining analysis of the unstructured data, accident types and causes of accidents were analyzed by construction costs at sites less than 5 billion won. As a result, it was confirmed that there were differences in accident types and causes depending on the construction costs. It is hoped that the results of this study will be used for customized safety management at small and medium-sized construction sites.

Insufficiency of special knowledge and construction cost makes it difficult in build a customized-feed service system in the agricultural and livestock industry In this paper, customized-feed service system was developed in the internet service environment by using digital information and technology as a grafted system. This system has a couple of advantages like economic feed supply and effective management of feed production cost which make it possible to establish a customized-feed database suitable for the working environment in the agricultural and livestock industry. And this system is expected as a solution for 21st century digitalized agricultural and livestock industry which make it certain in real time by constructing a network environment and digitalizing the equipment and component related to the farm production.

Since ICT convergence became a major issue, German government has carried forward a policy 'Industry 4.0' that triggered ICT convergence with manufacturing. Now this trend gets into our stride. From this facts, we can expect great leap up to quality perfection in low cost. Recently Korean government also enforces policy with 'Manufacturing 3.0' for upgrading Korean manufacturing industry with being accelerated by many related technologies. We, in the paper, developed a custom-made operational big data analysis platform for the implementation of operational intelligence to improve industry capability. Our platform is designed based on spring framework and web. In addition, HDFS and spark architectures helps our system analyze massive data on the field with streamed data processed by process mining algorithm. Extracted knowledge from data will support enhancement of manufacturing performance.

In this paper, an implementation method of augmented reality (AR) technology using Web 3.0 information services in the field of disaster response is proposed. The structure and characteristics of semantic web-based Web 3.0 are realized and a AR based mobile visual search (MVS) applied in the disaster sites is described. Based on Web 3.0 and AR MVS, a semantic web ontology oriented configuration scheme for disaster-related information and the communication scheme of information provided by AR technology are proposed. For the purpose of providing disaster-related and customized information to the disaster response site quickly and accurately, a method of leveraging Web 3.0 information services in AR technology is presented.
