This study is intended to examine the effect of photoluminescent exit signs in the event of failure of both the power to the lighting and illuminated exit sign. To achieve the purpose, the test house was exhibited in Fire EXPO '05. 520 visitors were examined from May 26-29, 2005. The results of this study are as follows; The evacuation from buildings in dark conditions showed that $70\%$ of men and $72\%$ of women were crawled along the wall. Meanwhile, $88\%$ of men and $83\%$ of women were evacuated with ordinary walking in photoluminescent exit signs. The egress time was shortened from 53 seconds to 64 seconds in accordance with age, height and visual power. The photoluminescent exit signs located on public buildings floors will aid in evacuation from buildings in the event of failure of the power to the lightings and illuminated exit signs.

In this paper, we present Emergency exit signs are installed to provide escape routes or ways in buildings like shopping malls, hospitals, industry, and government complex, etc. and various other places for safety purpose to aid people to escape easily during emergency situations. In case of an emergency situation like smoke, fire, bad lightings and crowded stamped condition at emergency situations, it's difficult for people to recognize the emergency exit signs and emergency doors to exit from the emergency building areas. This paper propose an automatic emergency exit sing recognition to find exit direction using a smart device. The proposed approach aims to develop an computer vision based smart phone application to detect emergency exit signs using the smart device camera and guide the direction to escape in the visible and audible output format. In this research, a CAMShift object tracking approach is used to detect the emergency exit sign and the direction information extracted using template matching method. The direction information of the exit sign is stored in a text format and then using text-to-speech the text synthesized to audible acoustic signal. The synthesized acoustic signal render on smart device speaker as an escape guide information to the user. This research result is analyzed and concluded from the views of visual elements selecting, EXIT appearance design and EXIT's placement in the building, which is very valuable and can be commonly referred in wayfinder system.

This paper proposes and implements a LoRa-based emergency exit guide system which can direct the optimal refuge path accounting for the real state of the fires. Each 4-way emergency exit guide sign presents a right direction through one of four LED signs toward the possible exit dynamically calculated by the shortest path algorithm. We constructed a simulation environment with 8 spots of the emergency exit guide signs and 2 exits, which can simulate variant cases of fire accidents, and showed that the proposed algorithm can presents the right guidance for each emergency exit guide sign. We also evaluated the performances of LoRa-based wireless communications using a self developed communication module in the various indoor and outdoor environments. The proposed system can be applied to small and medium sized buildings as well as larger ones in terms of cost efficiency, in which there's no needs to invest for the complex equipments except only sensors and emergency exit guide signs.

Korea has been preparing and operating crisis management standardized manuals so that over 30 disaster types that need to be managed at the national level can be selected and systematically managed. This study analyzed the crisis alert levels of two standard manuals related to the case with reference to the contents of the Framework Act on the Management of Disaster and Safety and National Crisis Management Basic Guidelines. According to the Act and Guidelines, crisis alerts are issued before a crisis or disaster, but the criteria of crisis alerts of the two manuals showed that the national crisis had already occurred and the disaster occurred due to a marine vessel accident at the serious level. In addition, the results of timing of issuance of crisis alert were reviewed. If the signs can be identified, a crisis alert may be issued prior to the occurrence of the incident, but a crisis alert cannot be issued when an incident occurs without a sign. In the case of an incident where there are no signs, but there is a possibility of spreading to a national level disaster, the disaster management supervision agency could issue a crisis alert.

Objectives : The aim of this paper is to examine the mechanisms of spontaneous sweating and night sweating, their relationship and how the explanations of their mechanisms have changed over the course of time, through examination of past discussions on spontaneous sweating and night sweating. Methods : Contents in classical medical texts that mention the mechanisms of spontaneous sweating and night sweating among search results from databases such as the Siku Quanshu were analyzed, followed by examination of each of their mechanisms, and their relationship with each other. Results & Conclusions : The cause of night sweating before the 『Danxixinfa』 was seen to be caused by yang deficiency in relation to problems of Exterior Qi and the theory of 'Heart governs perspiration', as the focus was on the phenomenon of sweating. However, it seems that yin deficiency came to be seen as playing a more fundamental role in the process of determining the root cause of night sweating. Moreover, Zhu Danxi's emphasis on nurturing yin, the composition of Dangguiliuhuangtang, and the development of the fire-heat pathology since the Jin Yuan period added to this shift in perspective. Night sweating from Shanghan could be seen as a sign of the already damaged Exterior Qi becoming more deficient while the pathogenic qi is in the half-exterior-half-interior zone, or as the pathogenic qi which entered with the Exterior Qi unsettling yin, or as a result of heat that is produced in the struggle between healthy qi and pathogenic qi that happens when Exterior Qi enters. Night sweating from miscellaneous disease could be seen as a sign of a deficient exterior that resulted from excessive entering of the Exterior Qi during yin deficiency, or resulting from relatively excessive Exterior Qi to deficient yin, producing heat that leads to sweating. If yin is not cultivated during the night but rather consumed leading to deficiency of Exterior Qi which also needs to be cultivated during night time, it could result in sweating.

Nowadays, the most of commercial buildings are build-out with complex architecture and decorated with more complicated interiors of buildings so establishing intelligible escape routes becomes an important case of fire or other emergency in a limited time. The commercial buildings are already equipped with multiple exit signs and these exit signs may create confusion and leads the people into different directions under emergency. This can jeopardize the emergency situation into a chaotic state, especially in a complex layout buildings. There are many research focused on implementing different approached to improve the exit sign system with better visual navigating effects, such as the use of laser beams, the combination of audio and video cues, etc. However the digital signage system based emergency exit sign management is one of the best solution to guide people under emergency situations to escape. This research paper, propose an intelligent evacuation route GUIDE that uses the combination centralized Wireless Sensor Networks (WSN) and digital signage for people safety and avoids dangers from emergency conditions. This proposed system applies WSN to detect the environment condition in the building and uses an evacuation algorithm to estimate the safe route to escape using the sensor information and then activates the signage system to display the safe evacuation route instruction GUIDE according to the location the signage system is installed. This paper presented the prototype of the proposed signage system and execution time to find the route with future research directions. The proposed system provides a natural intelligent evacuation route interface for self or remote operation in facility management to efficiently GUIDE people to the safe exit under emergency conditions.

On the viewpoint of Nae-Kyung and Ju-Yeok, the Seok-Kok's Pu-Yang-Non and other oriental medical doctor's Po-Eum-Eok-Yang, Pu-Yang-Eok-Eum theory which are on the basis of the Kun-Shin-Sang-Wha theory of Nae-Kyung and Myung-Mun theory of Nan-Kyung were compared and studied. The results were as follows : 1. Ju-Yeok and Nae-Kyung said the South is Fire. And explained it as the chief object of life activity by likening to king or saint. And said the North is Water. but didn't mentioned that there exists Fire. The activity of Kun-Wha is regarded as the the chief object of life activity and the Shin-Su can be vatalized by receiving the Shim-Kun-Wha. Therefore, the Seok-Kok's opinion that Shang-Wha is the Fire received by Shin-Su matchs the theory of Nae-Kyung and Nan-Kyung. 2. The Kidney(Shin) in Nae-Kyung means Puk-Bang- Han-Su(The North Cold Water) which has two characters, charging and discharging, ascending and descending. The paragrap "Kam-Ga-Seub(坎加習)" in Ju-Yeok means Puk-Bang-Su(The North Water) which also has two characters, charging and discharging, ascending and descending. The beginning and the end. And One Eum and Two Yang of Ri Sign of divination(離卦) cannot be divided into Su-Jang and Wha-Jang, the same as that, One Yang and Two Eum of Kam Sign of divination(坎卦) is Puk-Bang-Han-Su which cannot be divided into Shin and Myung-Mun. The theory of Choa-Shin-Woo-Myung-Mun of Nan-Kyung is the result that the Shin which has two characters is regarded as two organs. Therefore, from the viewpoint of Nae-Kyung and Ju-Yeok, the Seok-Kok's opinion that the Shin is the Puk-Bang-Han-Su which charges from the right and discharges to the left is more proper. 3. For the first time, the right kidney(Woo-Shin) defined as Myung-Mun in the Nan-Kyung and it is trailblazing theory which dosen't exist in the Nae-Kyung. But from the viewpoint of Nae-Kyung, Myung-Mun-Shang-Wha which some oriental medical doctors thought importantly is considered as Shim-Po which is in charge of the order of Shim(心命). 4. The rush of heat to the upper part(上熱) is raised by blind acting of Shang-Wha which exists in the lower part. This theory is on the basis of the Myung-Mun-Shang-Wha theory of Nan-Kyung. The theory that Wha is in the Shin(Kidney) doesn't exist and only the theory exists that the fever happens by the Kun-Wha not going down but ascending in the Nae-Kyung. Therefore the Shang-Wha blind acting theory of the lower part is not coincided with the theory of Nae-Kyung. 5. When the Vital power(陽氣) is blocked by bad tendencies(邪氣) like uncontrolled joy and anger or too much cold and heat etc, the trapped heat(鬱熱) or Ascending Shang-Wha apper, so Vital power itself cannot have blind activity or excess. Therefore, the theory of oriental medical doctors that the remaining vital power is the fire(氣有餘便是火) cannot be materialized. 6. On the basis of the Woo-Shin-Myung-Mun theroy, oriental medical doctors attached importance to Shin-Eum and Shin-Yang. So they emphasized on Ja-Eum-Gang-Wha or On-Bo-Shin-Yang for curing the Fire. Contrarily, On the viewpoint of siding with the vital power which is the Good and repressing the bad tendency which is the Bad, and another viewpoint that when the vital power which is Shim-Kun-Wha moves through the body consistently and fills up the body, then the enery and blood can be made, the Seok-Kok's theory is coincided with the theory of Nae-Kyung.

In Chemical, Biological, Radiological and Nuclear (CBRN) disaster, integrated and optimized equipment package including stretcher, isolation unit, patient monitoring and treatment equipment is essential to achieve proper treatment and prevent secondary contamination. The purpose of this study was to evaluate the efficiency and ease of use of integrated CBRN disaster equipment package for disaster medical response. This study was a randomized crossover study using a manikin simulation for emergency medical technitian (EMT). All participants used the existing devices and prototype of integrated CBRN disaster equipment package alternately. Efficiency was measured by time from vital sign change to detection or treatment application. Ease was use was measured by questionnaires for each patient monitor, stretcher care and isolation unit. 12 EMTs were enrolled. hypoxia-detection time of integrated equipment group was significantly shorter than existing equipment group (4.9 s (3.8-3.9) vs 3.5 s (2.5-3.9), p < 0.05). There was decreasing tendency of ECG change detection and facial mask oxygen supply but no statistical significance was observed. Overall satisfaction of patient monitoring device in integrated equipment group was significantly higher than existing devices (4(3.5-5) vs 3(3-3), p < 0.05). The use of integrated CBRN disaster equipment package shortened the hypoxia detection time and improved usability of vital sign monitor compared to existing devices.

This paper was carried out to survey fire hazard and improvement at the drain pump in air-conditioners. Based on the results of analysis, the proposal of electrical accidents prevention and a construction improvement are as follows. A power connection of the drain pump has two types, an electrical outlet type and direct connection type at control board of air-conditioner. The electrical outlet types need a bulletin sign or education as malfunction of the drain pump include an additional accidents, current leakage and overflowing with water on the floor from breaker trip by exterior cause and breaker off by mistake of worker. On the other hand, the direct connection types prevent a power interruption as exterior cause, but it has some trouble, cut of ground cable and without protection device. Usually it doesn't work by electrician when air-conditioner and the drain pump power work. Therefore an education or countermeasures are recommended for not electrician. Generally malfunction of the drain pump causes accumulated materials into the tank. Even though the accumulated materials lead to an overheating and burning as failure of detector occur an idling, periodic inspection of the air-conditioner filter and the drain pump tank prevent the trouble.
