육상으로부터 다양한 고급 정보를 전달 받아서 항해의 안전성과 효율성을 높이는 항해지원 기술의 필요성이 제기되고 있고, 이러한 맥락에서 e-navigation에서도 육상-선교간 정보 교환을 토대로 항해 관련 정보를 주고 받는 기술에 대해 강조하고 있다. 본 연구에서는 실시간 항행정보시스템의 구축을 위한 요소 기술 개발 단계에서 개발된 교통정보 및 사고정보 모듈을 실선에 탑재하여 실해역 시험을 수행하고, 실해역 시험 결과를 통해 파악된 문제점을 분석하여 향후 실시간 항행정보시스템의 구축 방향을 정비할 수 있는 방안을 마련하였다. 실험 결과, 육상과 선교간 통신 인프라의 한계를 체감하였으며, 실시간 항행정보시스템에서 육상-선교간 정보 컨텐츠 뿐만 아니라, 제한된 통신 인프라에서의 정보 교환 방법에 대한 적극적인 해결 방안이 마련되어야할 필요성을 인지하였다.

This paper describes the result of a case study for developing an expert system framework in order to support Korean Army tactical C4I system. Korean Army had developed an expert system, STAFS(Situation & Threat Assessment Fusion Expert System), for supporting field intelligence analysis activities which has been implemented through traditional manual process inside the division level combat briefing room. STAFS, however, has serious limitations for supporting combat commander's decision making processes because of its limited capabilities, since the system had been developed for supporting only intelligence analysis function rather than for integrated combat decision making processes inside the combat briefing room. Thus, this paper proposed an integrated expert system framework for supporting the commander's decision making by addressing various activities implemented in the briefing room.

The government has proposed various policies to 'extend the time for teaching information education in elementary schools'. However, in the 2022 revised practical arts (technical·home economics) curriculum, information education is still organized for only 17 hours the same as before, and there is not enough connection with the middle school information subject. In this study, policies related to information education in elementary schools such as National Strategy of Artificial Intelligence, Comprehensive Plan of Information Education, Education Policy Direction and Core Tasks in the Artificial Intelligence Era, and Digital Talent Education Plan were analyzed. In addition, after the '2022 revised national curriculum guidelines' was announced in 2021, the problems of the practical arts curriculum were analyzed by analyzing materials of the draft proposal of the curriculum and comments posted on the Public Participation Communication Channel. Finally, I suggested a plan to link the 2022 revised practical arts (technology·home economic) curriculum to the information subject of middle school in detail, and to expand information education in elementary schools.

This study is to analyze impact of geography and timing on the real transactions prices of apartment complexes in Seoul using data provided by the Ministry of Land, Infrastructure and Transport. The average real transactions and location data of apartment complex was combined into the GIS data. First, the pattern of apartment real transaction price change by period and by area was analyzed by kriging, the one of the spatial interpolation technique. Second, to analyze the pattern of apartment market price change by administrative district(administrative 'Dong' unit), the average of market price per unit area was calculated and converted to Moran I value, which was used to analyze the clustering level of the real transaction price. Through the analysis, spatial-temporal distribution pattern can be found and the type of change can be forecasted. Therefore, this study can be referred as of the base data research for the housing or local policies. Also, the regional unbalanced apartment price can be presented by analyzing the vertical pattern of the change in the time series and the horizontal pattern of the change based on GIS.

기존의 제어실 정보표시는 계통 및 기기정보를 바탕으로 하는 사건중심의 나열식 정보표시체계를 가지므로써 운전원이 표시되는 정보를 검색하고 판단하기까지는 많은 정신적 부담이 있었으며 이로 인한 운전오류가 많이 발생하였다. 이에 따라 본 논문은 일체형원자로(SMART:System-integrated Modular Advanced ReacTor) 제어실에서 운전원이 감독자 기능을 지원할 수 있도록 운전원이 쉽고 빠르게 필요한 운전정보를 검색하여 필요한 조치를 취할 수 있는 정보체계를 제안한다.

만일 고속도로가 없다면? 전화가 없다면? 인터넷이 안된다면? 인간과 인간, 공간과 공간 사이의 네트워킹이 끊긴 상황을 상상하는 건 쉽지 않은 일이다. 과학기술 R&D에 있어서도 마찬가지다. R&D의 거대화로 시간과 공간의 제약 없이 진행되는 원격연구의 필요성이 급증하면서 협업을 가능하게 해주는 네트워킹 즉 초고속연구망의 중요성은 날로 커지고 있다. 오늘의 주인공 '초고속연구망개발실' 사람들이 밤낮을 잊은 채 바빠야만 하는 이유가 바로 거기에 있다.

This study aims to examine how practices in beats have changed before and after the opening of press rooms and the operation of the briefing system. This research conducted in-depth interviews with 19 beat reporters and government officials. In conclusion, results showed that the Participation Government's press policy had a significant influence on practices in the press room. The opening of the press room and the operation of the briefing system contributed to the improvement of several bad practices in beats. However, some negative aspects of the briefing system were found in the research. Beat reporters' interviews were limited, thus threatening citizens' rights to know.

The need for estimating the real transaction price of land is increasing in order to build foundation for transparent land transaction and fair taxation. This study looked into the applicability of cokriging combining real transaction price of land, altitude and gradient for effective price estimation on the points where the real transaction does not take place in the course of using the real transaction price of land. The real transaction price of land have been estimated using the real transaction materials of Yeongcheon, Gyeongsangbuk-do from January 2012 to June 2014, and the results have been compared with the estimation results of ordinary kriging. As a result of analyzing the mean error and root mean square error (RMSE) of the estimated price and 2,575 verification points, it was found that compared to ordinary kriging, cokriging results were more effective in terms of the real transaction price estimation and actualization. The reason that cokriging is more effective in the real transaction price estimation is because it takes account of altitude and gradient which are the forces influencing the land value.

This paper presents the 2D/3D conversion technique using depth map which is generated based on the haze and relative height cue. In cases that only the conventional haze information is used, errors in image without haze could be generated. To reduce this kind of errors, a new approach is proposed combining the haze information with depth map which is constructed based on the relative height cue. Also the gray scale image from Mean Shift Segmentation is combined with depth map of haze information to sharpen the object's contour lines, upgrading the quality of 3D image. Left and right view images are generated by DIBR(Depth Image Based Rendering) using input image and final depth map. The left and right images are used to generate red-cyan 3D image and the result is verified by measuring PSNR between the depth maps.
