In the homepage of 16 municipal provincial office of education, school information service displays text-based results through search step or presents the simple information of the selected area when an area is clicked on the static image map. And it has several problems such as server load and slow transfer speed by the search of the synchronous transfer. Thus, in this study, we used the open API of Google map to provide location-based school information and implemented the mash up service for school information with the Ajax program of asynchronous transfer to reduce server load and to increase transmission speed. This service gives the efficiency and convenience to students, teachers, parents and education family members of various levels because it includes the location with school information on a dynamic map.

A Global Navigation Satellite System (GNSS), which is typically exemplified by the Global Positioning System (GPS), employs a open signal structure so it is vulnerable to spoofing electronic attack using a similar malicious signal with that used in the GPS. It is necessary to require a spoofing test evaluation environment to check the risk of spoofing attack and evaluate the performance of a newly developed anti-spoofing technique against spoofing attacks. The present paper proposed a simulation method of spoofing environment based on simulator that can be implementable in a test room and analyzed the spoofing simulation performance using commercial GPS receivers. The implemented spoofing simulation system ran synchronized two GPS simulator modules in a single scenario to generate both of spoofing and GPS signals simultaneously. Because the signals are generated in radio frequency, a commercial GPS receiver can be tested using this system. Experimental test shows the availability of this system, and anti-spoofing performance of a commercial GPS receiver has been analyzed.

This study was conducted from February 2005 to October 2007 to investigate bird distribution at three types of forest (mixed, broadleaf and coniferous) in Gwangneung forest. As a result, more birds used mixed forests than broodleaf and coniferous forest. During forest was opened to public, more birds also frequently used mixed forests. When forest was closed to public, there was no preference among three forest types. We also compared the number of species and individuals between open and restricted area. More species and individuals used restricted area.

This study was conducted to investigate the clear concept of patient safety and obtain theoretical evidences. Methods Research was conducted using Walker & Avant's conceptual analysis process. Results: Patient safety was defined as a activity that minimizes and removes possible errors and injuries to patients. It includes a basic desire to secure the patient's right to safety, and the legal regulations and duties of medical teams. The results of the establishment of a safety culture are patient-centered medical treatment and caring. Antecedents were found to be open and clear communications, continuous education and training for health care personnel, sufficient allocation of qualified personnel, cooperation among departments, improvements in the recognition of patient safety. Consequences were found to be the provision of high quality medical care and treatment, and increase in patient satisfaction. Conclusion: Patient safety as defined by the results of this study will contribute to the foundation of institutionalization of the pursuit of patient safety and creation of a hospital culture focusing on patient safety as a first priority.

In this paper, we proposed and implemented the effective automatic foreground motion detection algorithm that detect the foreground motion by analyzing the digital video data that captured by the network camera. We classified the background as moving background, fixed background and normal background based on the standard deviation of background and used it to detect the foreground motion. According to the result of experiment, our algorithm decreased the fault detection of the moving background and increased the accuracy of the foreground motion detection. Also it could extract foreground more exactly by using the statistic information of background in the phase of our foreground extraction.

최근 성인들 중에서도 취미로 가지고 노는 장난감 즉 '키덜트 장난감'의 관심도가 증가하는 추세이다. 그 중에서도 높은 매출 상승세를 보이는 RC카와 VR은 지속적으로 시장규모를 성장시키기 위해서 추가적인 콘텐츠가 필요하다고 판단된다. 그러므로 본 프로젝트는 두 아이템을 융합하여 차별적 콘텐츠가 있는 RC카 개발을 목표로 한다. VR기기 영상을 보면서 컨트롤러로 RC카를 조종하는 구성이며, 특징적인 콘텐츠로는 OpenCV 컴퓨터비전 알고리즘을 활용하여, 트랙내의 차선, 표지판 등을 인식하고 안전주행 점수를 평가하는 Score모드가 있다. 결론적으로 RC카와 VR을 동시 활용하는 것이 특징인 본 프로젝트는 높은 H/W 독립성, 확장성을 가지며, S/W적으로는 혼합현실적 요소를 체험할 수 있다. 나아가 사회적인 의미로 여러 세대가 함께하는 유익한 놀이 콘텐츠의 활성화를 기대할 수 있다.

An implicit method of solving the six degree-of-freedom rigid body motion equations based on the second order Adams-Bashforth-Moulten method was utilised as an improvement over the leapfrog scheme by making modifications to the rigid body motion solver libraries directly. The implementation will depend on predictor-corrector steps still residing within the hybrid Pressure Implicit with Splitting of Operators - Semi-Implicit Method for Pressure Linked Equations (PIMPLE) outer corrector loops to ensure strong coupling between fluid and motion. Aitken's under-relaxation is also introduced in this study to optimise the convergence rate and stability of the coupled solver. The resulting coupled solver ran on a free floating object tutorial test case when converged matches the original solver. It further allows a varying 70%-80% reduction in simulation times compared using a fixed under-relaxation to achieve the required stability.

Purpose: Since the 1990s, there has been an increasing interest in patient safety and quality of care. As a result, undergraduate nursing students have difficulties in clinical nursing practice such as health assessment or providing nursing skills. The purpose of this paper was to review current issues related to use of simulations in nursing education. Method: We conducted a thorough literature review including related proceedings to identify present issues in use of simulation education in nursing. Result/Conclusion: Simulation education in nursing differs from that in medical science. In nursing education, we need to focus on developing competencies for nursing students, for example, nursing process, nursing skills, and therapeutic communication skills With an increasing number of human patient simulators, we suggest a more careful approach including faculty development, curriculum development, and cost effective strategic planning. We propose a reliable and valid scenario development among nursing faculty as a consortium in the future.

This design plan aims at the designing of the pharmacy counter as the space in which the two inter-related elements of the pharmacy, for example, the pharmacist and the customers, selling medicines and transmitting health informations, etc. keep in contact with each other. To create an ambience of intercommunication for health care and relaxation, it must be set up the basic concepts like Functionality, Flexibility, Transparence and Material-Change. As the design solutions : - first of all the long counter must be divided into the independent places with character and function. - in accordance with the basic concepts functionality and flexibility each small counter must represent a one's own form language that is determined according to a given function and also open and flexible to the change of the situation. - the various kinds of display module are introduced to bring out the functionality and the aestheticity simultaneously. - to make a contrasting image to each other various materials are arranged on and around the counters.

IMT-2030(6G)은 IMT-2020(5G)에 비교하여 많은 서비스와 기능들이 추가되고 있다. IMT-2030(6G) 요소기술 개발은 산업계에서 매우 빠르게 진행되고 있으며, 이러한 기술을 기반으로 표준개발이 ITU-R WP 5D, 3GPP 등 여러 기구에서 동시다발적으로 진행이 되고 있다. Open RAN은 시점으로는 5G 이후에 출현한 기술이지만 5G를 기반으로 실현이 가능함을 산업계에서는 보여주고 있다. 이러한 기술들을 구분 짓고 체계화 하는 것이 표준기구의 역할이라고 할 수 있다. ITU-R WP 5D 제44차 회의(2023년 6월)에서 이번 회기(2020-2023)를 종료하며 완성한 IMT Framework 문서의 내용을 기반으로 AI와 정보보호가 융합한 지능형 보안관제의 필요성, 구조와 기능에 대하여 살펴본다.
