  • The secure access the lighting, Heating, ventilation, and air conditioning (HVAC), fire safety, and security control boxes of building facilities is the primary objective of future smart buildings. This paper proposes an authorized user access to the electrical, lighting, fire safety, and security control boxes in the smart building, by using color grid coded optical camera communication (OCC) with face recognition Technologies. The existing CCTV subsystem can be used as the face recognition security subsystem for the proposed approach. At the same time a smart device attached camera can used as an OCC receiver of color grid code for user access authentication data sent by the control boxes to proceed authorization. This proposed approach allows increasing an authorization control reliability and highly secured authentication on accessing building facility infrastructure. The result of color grid code sequence received by the unauthorized person and his face identification allows getting good results in security and gaining effectiveness of accessing building facility infrastructure. The proposed concept uses the encoded user access authentication information through control box monitor and the smart device application which detect and decode the color grid coded informations combinations and then send user through the smart building network to building management system for authentication verification in combination with the facial features that gives a high protection level. The proposed concept is implemented on testbed model and experiment results verified for the secured user authentication in real-time.

  • During the repair and restoration of the Daewoongjeon Hall of Youngguksa Temple, species identification and tree-ring dating for both present wood elements and charred ones excavated under the Hall, were conducted. The species of 74 wood elements of Daewoongjeon Hall, were identified as Pinus densiflora Sieb. et Zucc. and only 1 was identified as exotic Pinus species. The latter wood, which was used in the laths, seems to have been replaced during past repairs. Many documentary records and various artifacts pertaining to Youngguksa Temple are being excavated, but none described precisely the construction date of the present Daewoongjeon Hall. Also, from beneath the Daewoongjeon Hall, cornerstone and foundation of previous building and several charred wood elements were excavated. In comparing the direction of the stone columns of foundation of the previous structure and the existing Daewoongjeon Hall, the previous structure was rotated in an angle of approximately $15^{\circ}$. Therefore, in order to find the association of the previous structure with the present Daewoongjeon Hall, tree-ring dating was conducted. The dating of 41 original timbers and 14 roof-filling timbers of the present construction elements revealed that the last annual ring was of A. D. 1703 with complete latewood, indicating that those woods was cut some time between the autumn of 1703 and spring of 1704, and the building was erected in 1704 when we assume no period of wood storage. The year of the last annual ring of the charred elements, which were excavated from beneath the Daewoongjeon Hall, was analyzed as 1674. The cutting year of the woods used for the present building began in 1698, therefore, it can be presumed that the Daewoongjeon Hall before the fire was a structure that was elected shortly after 1674 and that a catastrophic fire occurred some time between 1674 and 1698.

  • 최근 경찰서 등과 같은 관공서로 허위 신고를 하는 경우가 줄지 않고 있는 실정이다. 이로 말미암아 실제 신속한 출동과 대응이 필요한 강력 범죄나 화재가 발생하였을 경우 이를 제때에 가지 못하여 이에 따른 인명 피해 등이 발생할 수 있게 된다. 또한 허위 신고로 말미암은 경찰력과 행정력의 낭비 또한 매우 심각한 문제를 야기할 수 있다. 이를 위해 본 논문에서는 경찰서에 신고 된 실제 음원을 기반으로 실제 신고와 허위 신고의 음성 차이가 무엇 인지를 규명해 내는 연구를 수행하고자 한다. 아울러 향후 이를 기반으로 거짓 신고와 실제 신고를 판별해 내는 허위 신고 판별 시스템을 개발하고자 한다.

  • Objectives : Indirect contact with trauma may occur when a person empathically listens to detailed descriptions, exposing the person to intense emotional pain from trauma victims. Although less severe than direct trauma, indirectly traumatized persons may experience the same fear, rage, and despair as direct trauma victims. This phenomenon has been variously termed vicarious trauma, traumatic countertransference, burnout, compassion fatigue, and secondary traumatic stress. Using a psychiatric symptoms questionnaires, this study investigated the effects of indirect exposure to co-worker's trauma on the mental health of firefighters who had not directly experienced traumatic events in the previous year. Methods : We administered self-report questionnaires, such as the Impact of Event Scale-Revised (IESR) and Alcohol Use Disorder Identification Test (AUDIT), to firefighters working at two fire stations in a metropolitan city. We analyzed 188 of 232 collected surveys, after excluding falsely entered data (28 cases) and questionnaires by directly-traumatized victims (16 cases). Results : Alcohol consumption and posttraumatic stress disorder (PTSD) symptoms, as determined by the AUDIT and IES-R, were significantly higher in the indirectly-traumatized group. The ratio of high-risk members scoring higher than 23 in IES-R was larger in the indirectly traumatized group, although this was not statistically significant. Conclusion : Alcohol consumption was significantly higher in the indirectly traumatized group. This group also included more members at high risk for PTSD. Further research, with a larger group of indirectly traumatized firefighters and ongoing investigation of PTSD development and other psychiatric symptoms, is needed.

  • 본 연구의 목적은 소방공무원의 음주 실태를 파악하고 음주수준과 직무스트레스의 관계를 분석하기 위함이다. 연구대상은 C지역, K지역, P지역의 소방공무원 267명으로 설문을 통해 음주 실태와 직무스트레스를 측정하였다. 연구결과 음주수준은 정상음주군 152명(56.9%), 문제음주군 115명(43.1%)이었고, 음주 빈도는 2-4 회/월 83명(31.1%), 음주량은 10잔 이상 101명(37.8%), 폭음 빈도는 매일이 77명(28.8%)으로 가장 높게 나타났다. 직무스트레스가 높은 군에서 문제 음주군이 될 위험도가 높았고(OR = 5.458, 95% CI = 1.108 - 26.886), 그 중 대인관계 갈등이 음주수준에 영향을 미치는 주요 요인으로 나타났다(OR = .332, 95% CI = .134 - .820). 따라서 직무스트레스를 낮추고 대인관계 갈등을 줄인다면 음주 수준을 낮출 수 있을 것으로 기대된다.

  • Purpose: It is the responsibility of public healthcare to respond quickly to infectious disease outbreaks and disasters such as MERS, COVID-19, the Syrian earthquake, and the Miryang Sejong Hospital fire accident. It is very important to secure safe medical facilities and protect lives through emergency medical support and disaster response systems. The purpose of this study is to investigate the safety status of regional medical facilities that play a central role in the event of a disaster. Methods: The target was 41 local public hospitals, including 35 regional medical centers and 6 Red Cross hospitals nationwide. We delivered a questionnaire to 41 medical facilities and collected data from 32 regional public hospitals that received responses. Results: In order to respond to safety accidents, a survey was conducted on infections, falls, patient identification, and incorrect connections for medical accidents, and for in-hospital accidents, a survey was conducted on entrapment, collision, water leaks, falling objects, and crime prevention. For natural disasters, we investigated the response environment for typhoons, floods, and snow damage, and for social disasters, we investigated the response environment for fire, power outages, and radiation damage. Implications: We hope that it will be used as basic data for developing standards and creating hospital facilities and environments that are safe for everyone to respond to various disasters and prevent patient safety accidents in the future.

  • This study draws pattern differentiations of headache disorders on the ground of modern clinical applications and Korean medical literature. Categorization and symptoms of headache disorders are based on International Classification of Headache Disorders 3rd edition(beta version). And clinical papers are searched in China Academic Journals(CAJ) of China National Knowledge Infrastructure(CNKI). In the aspect of eight principle pattern identification, primary headache occurs due to lots of yang qi and has more inner pattern rather than exterior pattern, heat pattern rather than cold pattern, excess pattern rather than deficiency pattern. And primary headache is related with liver in the aspect of visceral pattern identification and blood stasis, wind and phlegm are relevant mechanisms. Migraine without aura is associated with ascendant hyperactivity of liver yang, phlegm turbidity, sunken spleen qi, wind-heat, blood deficiency or yin deficiency. Migraine with aura is mainly related with wind and it's major mechanisms are ascendant hyperactivity of liver yang, liver fire, yin deficiency of liver and kidney, blood deficiency or liver depression and qi stagnation. High repetition rate of tension-type headache can be identified as heat pattern or excess pattern. And trigeminal autonomic cephalalgias can also be accepted as heat pattern or excess pattern when the occurrence frequency is high and is relevant to combined pattern with excess pattern of external contraction and deficiency pattern of internal damage based on facial symptoms by external contraction and nervous and anxious status by liver deficiency. This study can be expected to be Korean medical basis of clinical practice guidelines on headache by proposing pattern identifications corresponding to the western classifications of headache disorders.

  • The aim of the present study was to investigate the development of theory of the deficiency of yin-yang in the spleen-stomach(脾胃). The spleen-stomach theory is a very valuable composition of the oriental medicine. Its first theoretical basis was established by Li Dong Yuan(李東垣) who wrote Piweilun("脾胃論"). He insisted the importance of spleen yang(脾陽) which is the "postnatal base of life" by transforming and transporting of food essence and fluids and raises the clear. After him, his theory had influenced many descendant medical men. one of them, Ye Tian Shi(葉天士) found out the differences of between stomach and spleen. Especially he focused on the stomach yin(胃陰) which is easy to be exhausted by dry-fire(燥火). And he also made another remedy, "the stomach yang should be moved well(宣通胃陽)", which emphasize on that cold and stagnant cause the deficiency of the stomach yang. After that, spleen yin(脾陰) theory was set up by Tang Zong Hai(唐宗海). His spleen yin(脾陰) was deeply related with digestive enzymes and pancreas, because his theory was established by comparing oriental and western medicine. These four theories became the theoretical basis of the deficiency of yin-yang in the spleen-stomach(脾胃), and similar symptom of the spleen-stomach(脾胃) could be categorized according to the pattern identification(辨證) which was developed from these four theory.

  • 국가적 그리고 사회적 피해 방지 노력에도 불구하고 보이스피싱으로 인한 재산 피해의 규모가 좀처럼 줄지 않고 있는 실정이다. 이는 최근의 보이스피싱이 세련된 말투와 전문용어를 사용함으로써 범죄자를 인지하기 어렵게 만들기 때문이다. 더 나아가 개인정보 취득과 실제 관광서등에서 근무하는 종사자들이 실제 현장에서 사용하는 전문용어를 구사하여 젊은 층을 집중적으로 속이고 있는 실정이다. 이는 결과적으로 노년층보다 판단력이 있는 20~30대의 젊은 층의 피해가 급증하고 있는 상황과 직결된다. 이를 위해 본 논문에서는 실제 보이스피싱에 사용된 보이스피싱의 음원과 보이스 피싱 범죄자와 동년배의 일반 젊은 층을 대상으로 같은 문장을 읽고 이에 대한 음성을 비교. 분석을 행하였다. 실험은 2011년 이후 최근까지 보이스 피싱을 행한 범죄자 목소리의 음성적 특징이 무엇인가를 음성의 음높이와 그 대역폭, 음성에 실리는 에너지 및 발화속도, 음색 등을 기반으로 수행하였다. 실험 결과 음성에 실리는 에너지와 발화속도에 있어 의미 있는 차이가 있음을 규명해 낼 수 있었다.
