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.

Sharehouse has been supplied as an alternative to solving the steadily increasing one-room housing problem of single-person households every year, and it is necessary to investigate the satisfaction of residents who actually live in sharehouse through P.O.E. Therefore, this study analyzed priror researches related to the existing one-person households, sharehouses, and satisfaction surveys, and summarized indicators with high relevance and frequency to derive satisfaction survey factors that can clearly evaluate the improvement architectural plan of sharehouses. As a result, it was classified into 4 items in the 'general information' category to investigate the status, housing rental type, and housing cost of the sharehouse, 15 factors in the 'peripheral environment' category to evaluate the safety, 3 factors in the 'community' category, and 17 factors in the space (facility) and service category. In the "General Information" section, the overall one-person housing satisfaction, desired sharehouse type, housing rental type, housing cost, and living expenses were reduced. In the "Surrounding Environment", accessibility to public office, accessibility to cultural facilities, accessibility to medical facilities, accessibility to work and school, convenience stores, noise pollution and safety. In addition, in the "community" section, it consists of interactions with various people, relationships with housemates and in the "space (facilities) and service" section, heating, waterproof, soundproof, ventilation, moisture and condensation blocking, facility management, interior, room size, built-in furniture, storage space, laundry, parking. Most of the scales for each factor were 5-point Likert scales, allowing evaluation of the degree of satisfaction, and some factors presented criteria to induce structured answers. Therfore, it is expected that the survey will be conducted on residents who actually live by deriving factors for the satisfaction survey of one-person households living in the sharehouse, and the current status of the sharehouse will be identified, and the degree of satisfaction will be analyzed to be used for research.

Recently, starting with the deep underground road construction plan in Seobu Expressway, Korea, there area many studies on deep underground roads to be newly built. However, there is an extreme lack of safety standards, which does not consider traffic conditions and road driving characteristics. Therefore, this study reviewed safety elements to reflect in the deep underground road planning by analyzing driving stability of longitudinal tunnels with road environments, which resemble deep underground roads. For comprehensive analysis, the characteristics and causes of the accidents that have occurred in seven longitudinal tunnels with a length of 2km or over in Gangwon area, were collected. Specifically, geometric structures and facilities of each tunnel were investigated. Also, the present state of facility installation and the changes in driving speed of vehicles passing through each tunnel were observed to analyze the causes for the traffic accidents in each tunnel and accident reduction alternatives. It was revealed that the most frequent accidents in the tunnels resulted from the changes of traffic flow due to the abrupt speed reduction of forward vehicles, or the failure in speed control of following vehicles during the traffic congestion situation. Moreover, installing facilities such as plane and longitudinal curves, median strips and marginal strips seem to induce consistent driving speed. These results mean that for accident prevention, speed management must be preceded and there is a need to develop and introduce safety facilities actively to control the driving flow of forward and following vehicles.

Purpose: In this study, we investigated the better application of the law which is about the AED installation and more effective ways of emergency medical care system, to understand the law and to research the current condition of public facilities which belong to local governments, and to seize the aspect of safety guards who currently work in order to provide the installation of AED in the public facilities and to provide more efficient emergency medical service with the effectuation of the immunity law of the good intention of first-aid treatment. Methods: In Gwang-ju, 234 public facilities have been identified by 31 December, 2008. With the exception of the duplication, we researched 158 facilities and received the answers from 95 of them. Results: In the research, 53% of them have had internal emergency first-aid education, and 55% of them didn't have this education and a CPR education manual, and 30% of the facilities even didn't know how to connect with the manager of the company for the first-aid department. On the other hand, most of them were highly interested in CPR and AED education on the ratio of 91% and 93%. 88% of them have been trained about first-aid, 51% of them haven't been retrained, 17% have never been trained. so, the reality of emergency system at public facilities is serious. 78% of them knew they are working at public facilities, though 49% of them didn't know about AED installation. 57% of them didn't know the fact there is the immunity law related with good intentions for first-aid treatment. 63% of the facilities have security guards, and 30% of them didn't answer the questions. Also, many of them agreed to the opinion that all employees should have first-aid training. At representative survey report of participator of public-facility, emergency treatment is 61%, 16% of patients calling. Accordingly they importantly think better doing an on-site first-aid than evacuating the patient. And the rates show that 57% of them answerers tend to call Fire-Office(119) for evacuating the patients, and 28% of them EMIC(1339) for the first-aid. Conclusions: In this study, we are suggest to improve the details of the efficient operations and management after the grasp of the uninstallation, indifference, and unreliable conditions of AED. 1) Need a publicity of AED install cognition which is an emergency medical instrument at public facilities. 2) Arrangement of safety agents at facilities and concerns about them for good management from the parties concerned. 3) Need a designation of legal details according to the decision of the AED installation and the standard of the AED installation. 4) Training about first-aid of safety guards and the persons concerned in the facilities should be practiced participation with the positive and through this, first-aid treatment could be done by anyone who knows the immunity law related to medical emergency. 5) The brochures for the potential users and the results form practicing the instructions need to be improved in many ways through recording the emergency cases that have happened.
