Human casualties from fires are increasing worldwide. The majority of human deaths occur during the evacuation process, as occupants panic and are unaware of the location of the fire and evacuation routes. Using an Internet of Things (IoT) sensor and reinforcement learning, we propose a method to find the safest evacuation route by considering the fire location, flame speed, occupant position, and walking conditions. The first step is detecting the fire with IoT-based devices. The second step is identifying the occupant's position via a beacon connected to the occupant's mobile phone. In the third step, the collected information, flame speed, and walking conditions are input into the reinforcement learning model to derive the optimal evacuation route. This study makes it possible to provide the safest evacuation route for individual occupants in real time. This study is expected to reduce human casualties caused by fires.

In this study, historical and cultural landscapes were reviewed focusing on Mangjinsan Mountain in Jinju, Gyeongsangnam-do, and the scenic value was examined through this. First, Mangjinsan Mountain was noted in history, as Ansan(案山, a mountain on the opposite side of a housing/grave site) in Jinju, where Bongsu(烽燧, the beacon fire station) is located. Information on Mangjinsan Mountain was gradually doubled due to its status, and the beacon fire station of Mangjinsan Mountain was in charge of defending the Jinju area. Mangjinsan Mountain was described as a symbolic landscape of Jinju. Regarding the etymology of Mangjinsan Mountain, Sung Yeo-Sin(成汝信) analyzed the geography of Jinju and suggested that it was a place name originating from the phoenix. However, looking at various records, it is confirmed that the name of Mangjinsan Mountain is maintained uniformly, but the inscription is not unified. Second, Mangjinsan Mountain became one of the major stage for the Japanese Invasion of Korea in 1592, and in 1597. It is confirmed to be a place which has joys and sorrows, for that it provided an opportunity to win the Siege of Jinju in 1592, but many casualties occurred in 1597. On the other hand, in the area of Mangjinsan Mountain Byeolseo(別墅), temples, and administrative facilities were located to establish cultural history of the time, and in the 19th century, Manggyeongdae Pavilion was built due to the scenic value of viewing Jinju Castle. These are examples of testimony how Mangjinsan Mountain has an important meaning in Jinju's history and culture. Third, in the late Joseon Dynasty, a poem reciting Mangjinsan Mountain appears, which shows that the Mountain has established itself as a scenic site in Jinju. The description of Mangjinsan Mountain is confirmed in the literature that lists the scenic sites of Jinju. On the other hand, writers who lived in Jinju paid attention to the beacon fire station, singing about the peaceful world without war and looking back the history. In the 19th century, Jeonbyeolyeon(a farewell party) was held, which seems to be the result of the beauty of viewing Jinju and overviewing the area. Through the facts, the symbolism and scenic value of Mangjinsan Mountain in Jinju were confirmed.

Satellite imagery was applied to locating archeological sites and remains around northeastern areas of China, called as Manchuria, and Korean peninsular, such as Mountain Fortress of Goguryeo Dynasty era($37BC{\sim}771AD$), and firing torch and smoke beacon signal sites at mountain tops in Josun Dynasty era($1392{\sim}1910AD$) as well as burial sites below the ground level in the modern era. Information on archeological sites, fire posts and burial places could be found in various literatures, but real figures of such cultural assets have been disappearing due to land development programs and human activities in recent years. Some of these historical sites were identified in satellite images using GPS(Geographical Positioning System). Real locations of these sites would be further necessary to be verified.

We propose an emergency rescue support communication system to quickly rescue passenger ships, such as large cruise ships, when a ship sinks or a disaster such as a fire occurs. A beacon is installed in the inside of the vessel, and the position and the status of the passenger are detected in real time through the Bluetooth communication in the mobile terminal carried by the passenger and transmitted to the server. When an emergency occurs, the server sends information on the passenger to the rescue agency, informs the passenger of the emergency, and guides evacuation. As a result of simulations using the designed system, it was confirmed that the server immediately notifies all terminals when an emergency occurred in more than half of the area. This system, which detects the accident in real time and notifies all terminals in the vessel, unlike the existing system that notifies the position of the accident vessel or simply the position of the passenger in the vessel, will be helpful for the rapid evacuation and rescue of the passenger.

The purposes of this study were to re-interpret the Traditional Korean Painting of Flower and Bird Patterns from a modern point of view and use them in apparel textile design. A literature review of the Traditional Korean Painting of Flower and Bird Patterns was made first, and then, through manual and Photoshop workings, two apparel textile designs were suggested. The results were as follows. First, Traditional Korean Paintings of Birds and Flowers are covered not only by decorative beauty but also by the common pure hope and ideology of loving and adoring nature, which is inherent in the symbolism and racial characteristics and high aesthetic sense appeared by ancestors' life feeling. The meaning that is symbolized by each subject matter appearing in the Transcontinental Painting of Bird and Flower is important, but the ancestors' deeper and affectionate desire is shown in the harmony and happy aspect of a picture where more than two subject matters appear, such as Song Hak do where pine is with crane, cockscomb with chicken, bamboo with beacon fire, or a couple of them with flower. Second, two kinds of textile designs were suggested. The motif of work 1 targeted professional women of activity and individuality in their late 30s to early 40s. The lotus blossom pattern was selected to present its concept, "Chic Elegance." The motif of work 2 targeted intelligent women in their mid 40s, and the peony blossom was selected to present its concept, "Romantic Elegance."

This article cites examples of cultural heritages that urgently require protection measures, and the reinterpretation of beacons, fortresses, and extremities identified in the process of conducting a cultural heritage investigation of the DMZ and bordering areas. It is true that there are various difficulties involved in implementing thorough protection measures considering the reality of the two Koreas' division. Despite this, the "Ordinance for the Protection of Military Cultural Properties" and the "Act on the Protection and Investigation of Buried Cultural Heritage" have been enacted and are in effect. In particular, in the "Ordinance for the Protection of Military Cultural Properties," the value of protecting "military assets" is emphasized. The identification and investigation of cultural heritages in the DMZ and border areas must continue. Although field research is currently difficult, the primary investigation conducted by high-altitude terrain analysis and literature research is considered effective. Furthermore, there are parts that require correction and supplementation with future field investigations. Although some trial and error is expected during these various cultural heritage investigations, they need to continue.
