코로나19의 영향으로 최근 국내에서는 야외 야영장에서의 캠핑을 즐기는 사람들이 크게 증가하였으며, 이와 더불어 최근 야외 캠핑장의 화재 발생 건수가 크게 증가하는 추세에 있다. 캠핑장과 같은 야영장 영업허가를 얻기 위해서는 「관광진흥법 시행규칙」에 따라 소화기를 적정하게 확보 배치해야만 하는 허가 기준이 존재하며, 그 기준은 야영장 2개소 또는 100미터제곱마다 소화기 1개 이상 설치하도록 되어있다. 그럼에도 화재가 많이 발생하는 이유로는 소화기가 설치되어있다는 것에 대한 인지 부족이라 생각된다. 한편, 야외에 설치되는 소화기는 상대적으로 그 유지관리가 어려울 것이라 판단된다. 따라서 본 프로젝트에서는 무게가 무겁지 않아 아이들과 노인들도 쉽게 사용할 수 있는 휴대용 소화기구, 사용 시 환경의 오염이 적은 소화기구, 여행객의 감성을 한층 증가시켜줄 수 있는 소화기구, 유지관리가 편리한 소화기구의 개발을 목적으로 하였다.

An local area weather condition monitoring system to minimize many disasters from the sudden change of weather condition in local and mountain ales is proposed. Firstly, the comparison of present state of the related monitoring systems and the possibility of realization with some merits are investigated. Moreover, this paper present direction of local area weather condition monitoring system based on integration of wireless sensor network and CDMA network following some case study. The sensor node for wireless sensor network and an interface dongle are fabricated for the system. The stand-alone software in cellular phone is also developed. Through the efficient integration of both networks, the measured weather condition data from sensors can be transmitted to the server or mobile to monitor with high reliability. The proposed monitoring system will guide new type of project in wireless sensor network and support alarm service of the sudden change of weather condition to mobile user from central official regulations.

The rapid development of the information technology has passed over the implementation of the virtual reality. It is realizing information services that are form of the globalization, based on the Internet. In addition, the effort to apply IT to public administration for public services has been made. The remarkable development of computer hardware has overcome the limit of the information distribution and emerged for practical use in various fields such as public institution, underground facilities management, tourism industry development etc. However, the practical use of Virtual Reality with Three-Dimensional GIS on disaster management by Korea National Emergency Management Agency is very much low. Therefore, this studies focus on how to use 3-Dimensional GIS for the purpose of fire disaster prevention. The studies also discussed, through understanding of the limitations of 2-Dimensional GIS, the establishment of basis for fire prevention technology development and its utilization among those ubiquitous city paradigms, which have become so much issues these days.

The outbreak of COVID-19 has had a huge impact on human life. The World Bank group (WBG) has stated that 2020 is the worst year since World War II for economic growth. An epidemic of an infectious disease such as COVID-19 is classified as a "social disaster" by law. The social disaster caused by COVID-19 puts certain industries, occupations and vulnerable groups at risk of exclusion and isolation. This paper intends to examine the fluctuations in the consumer price index in the cultural, sports and tourism sector before and after the onset of COVID-19. In addition, it predicts the consumer price index by sector until December 2021 and reveals its implications.

This research puts the purpose in elucidating the effect of participation types of leisure activity and leisure restraints on life quality. To achieve research purpose, questionnaire survey was conducted on 200 subjects who are engaged in private guard companies with ages over 20. Using the collected data, frequency analysis was conducted in order to identify demographic characteristics with SPSS/WIN 17.0V program. In addition, multiple regression analysis was conducted for solving research questions. As a result, sports related participation type had a positive effect on time constraint factor. Meanwhile, hobby related participation type had a positive effect on time and cost constraint, participation type of watching has a positive effect on individual and social constraint. Tour and play related participation type had a positive effect on individual constraint factor. Meanwhile participation type of sociality had a positive effect on individual constraint and hobby factor, but had a negative effect on familial and social constraint. Sports related participation type had a positive effect on social relationship factor. Participation type of watching and play related participation type had a negative effect on family relationship. Finally, time constraint factor had a positive effect on family relationship, and cost constraint factor had a positive effect on entire quality of life. Individual and family constraint factors had a negative effect on leisure relationship factor. Also, social constraint factor had a positive effect on family relationship, but had a negative effect on leisure relationship.

Floating architecture is the most effective way to accommodate itself to sea-level rise due to climate change. At the same time floating architecture is the best model to offer the new spatial experience through water-friendly environment. Domestic floating architecture is still on the early stage compared to Europe which has several companies specialized in designing and building floating architecture. Floating architecture is divided into 8 types according to its criteria such as program, form, scale, level, location, access, mobility and energy. The following are design characteristics of floating architecture : (1) composed of 2 stories, (2) having large deck, (3) designing rectangular plan and balanced mass, (4) maximizing view, (5) having water-friendly space, (6) multi-using space and minimizing surface, (7) planning section to control light reflecting from the water, (8) modular and unit system.

The global pandemics occurred in 2020 had a great economic impact on the world, and the impact was especially greater on self-employed people who were heavily affected by the floating population and tourism industry. To solve this problem, each country implemented emergency disaster support policies, and it was difficult to select the criteria and scope. The following research carried out two results. First, after analyzing the impact of global pandemics on the local economy, an economical index was defined that could explain the impact intuitively. Second, we propose linear programming methods to provide optimal budget policy using defined indicators, which present economic shock indicators and optimal years that can be considered quickly and easily by the government. Finally, the limitations and implications of the proposed study model are introduced.

Jeollanam-do has 25 land-to-island and island-to-island bridges, the largest number in Korea. It is a local government rich in specialized marine and tourism resources centered on the archipelago and the sea bridges connecting them. However, in the case of sea-crossing bridges, when strong winds or typhoons occur, there is an issue that increases anxiety among users and local residents due to excessive vibration of the bridge, apart from structural safety of the bridge. In fact, in the case of Cheonsa Bridge in Shinan-gun, which was recently opened in 2019, vehicle traffic restrictions due to strong winds and excessive vibrations frequently occurred, resulting in complaints from local residents and drivers due to increased anxiety. Therefore, based on the data measured using IoT measurement technology, it is possible to relieve local residents' anxiety about the safety management of marine bridges by providing quantitative and accurate bridge vibration levels related to traffic and wind conditions of bridges in real time to local residents. This study uses the existing measurement system and IoT sensor to constantly observe the wind speed and vibration of the marine bridge, and transmits it to local residents and managers to relieve anxiety about the safety and traffic of the sea-crossing bridge, and strong winds and to develop technologies capable of preemptively responding to large-scale disasters.

최근 COVID19 상황에서 생활 속 거리두기가 강조되면서 관광지나 다중이용시설 등의 이용객 수와 밀집도를 파악하는 것이 중요해지고 있다. 따라서, CCTV 영상을 활용하여 저렴한 비용으로 다중이용시설의 출입자수에 대한 정보를 실시간으로 모니터링할 수 있는 시스템이 필요하다. 이를 위해 본 논문에서는 딥러닝 실시간 객체인식기술을 활용한 출입자의 수와 동선을 측정하여 출입자에 대한 통계정보를 웹브라우저를 통해 제공하는 시스템을 개발하였다. 실시간 객체인식기술인 YOLOv4와 YOLOv4-tiny 알고리즘을 Nvidia사의 Jetson AGX Xavier 와 데스크톱PC에 적용하여 각 알고리즘의 FPS와 객체 인식률을 비교 분석 하여 알고리즘을 적용하였다.
