This study presents an analysis of comparison of P-type fire detection system with fuzzy logic-applied fire detection system. The fuzzy logic-applied fire detection system has input variables obtained by fire experiment of small scale with K-type temperature sensor and optical smoke sensor. And the antecedent part of fuzzy rules consists of temperature and smoke density, and the consequent part consists of fire probability. Also triangular fuzzy membership function is used for input variables and fuzzy rules. To calculate the final fire probability a centroid method is introduced. A fire experiment is conducted with controlling wood crib layer, cigarette to simulate actual fire and false alarm situation. The results show that peak fire probability is 25[%] for non-fire and is more than 80[%] for fire situation, respectively. The fuzzy logic-applied fire detection system suggested here is able to distinguish fire situation and non-fire situation very precisely.

With advantages of open spaces and existing HVAC facilities, subway station, if unexpected disastrous situation happens on the ground, can be used as a temporary safe place for evacuees. The main objective of this study is to establish a guideline on estimating evacuation capacity of the subway station and evaluating levels of service of evacuation for officials to control the situation. This guideline includes available spaces of the station, capacity of sanitary fixtures, and total number of passengers, etc. In this paper, we first analyzed the number of passengers of SMRT (Line 5~Line 8) during AM peak hour and then evaluated the number of passengers using toilets at that time. In addition, we calculated the seating capacity of subway stations on SMRT using the difference between the actual number of toilets and the estimated number of ones from the occupancy time of each toilet.

Smart-Phones are utilized in disaster management field because it can deliver disaster information to large population simultaneously and quickly, and provide accurate information through situation-based service using the LBS(Location Based Service). To study on the utilization of smart phone for disaster information collection and dissemination method, this study suggest a framework which connects smart phone by loading application for reporting disaster. The disaster monitoring and situation dissemination system framework using smart phone is composed of 4 parts. First, smart phone application enters image, video, voice and text information and location of the disaster. Second, the disaster report reception and situation dissemination server receives the information, save in the DB, and send through smart phone SMS. Third, store into disaster information database. Fourth, display the disaster report and management information on 2D GIS, support the decision making process in deciding whether to manage as disaster, and disaster management web service which disseminates situation.

This research investigates the factors influencing price sensitivity in fashion products. This study incorporates three essential variables, which were likely to influence price sensitivity: the subjective shopping value of consumers, objective purpose of use, and social situation according to the shopping companions of consumers. A sample of young adult consumers (who had purchase experience of fashion products during the last six-months) was surveyed using a self-administered questionnaire. A 3-way ANOVA was used to evaluate the data. The results show that the utilitarian shopping value of consumers was more sensitive in price than the hedonic shopping value and a self-using purchase was more sensitive in price than a gift-giving purchase. In addition, a correlation effect was significant between the purpose of use and social situation. In addition, the correlation effect among all of the three variables was also significant.

As the elderly population is becoming an aging society, the elderly are experiencing many problems. Social security costs for the elderly are increasing and the un-linked social phenomenon is emerging. Thus, the social infrastructure and welfare system established in the past economic growth period are in danger of not functioning properly. People socially isolated or with chronic diseases among the elderly are exposed to various accidents. Thus, an active healthcare management service is imperative. Additionally, in the event of a dangerous situation, the system must have ways to notify guardians (family or medical personnel) regarding appropriate action. Thus, in this paper, we propose the smartphone-based healthcare and emergency response service platform. The proposed service platform aggregates movement of relevant data in real-time using a smartphone. Based on aggregated data, it will always recognize the user's movements and current state using the human motion recognition mechanism. Thus, the proposed service platform provides real-time status monitoring, activity reports, a health calendar, location-based hospital information, emergency situation detection, and cloud messaging server-based efficient notification to several subscribers such as family, guardians, and medical personnel. Through this service, users or guardians can augment the level of care for the elderly through the reports. Also, if an emergency situation is detected, the system immediately informs guardians so as to minimize the risk through immediate response.

Purpose: The purpose of this study was to evaluate the nursing students' clinical judgment skills in simulation using Tanner's Clinical Judgment Model. Method: Forty-five teams of a total 93 nursing students participated in a post-operative patient care scenario using human patient simulator. Data were collected from students' responses in scenario and guided reflective journaling according to the framework of Tanner's model which comprised noticing, interpreting, responding, and reflecting on response. Data were analyzed using descriptive statistics. Results: The students' responses of the situation were in accordance with the goals of scenario, i.e. relieving patient' pain and preventing pulmonary complications. However, most of students needed clinical cues and focused on a given clue to solve the issues. They were lack of ability to collect additional information as well as connect the relevant clues in simulated clinical situation. Conclusion: The nursing students have difficulty in what they notice, how they interpret finding, and respond appropriately to the situation. The simulation training using Tanner's model could provide faculty and nursing students with an effective teaching and learning strategy to develop the clinical judgment skills.

The purpose of this study was to test the effect of the clothing purchasing situation on the preceived risk and information search behavior. Data were obtained from 369 students who were studying in Semyung University. The results of this study were as follows : 1. Students gave the clothing to their favorites as a gift 1 to 2 times in a year. And they thought self using purchasing was more important than gift giving purchasing. 2. In gift giving purchasing, perceived risks were higher than self using purchasing. But the economic risk was the exception. In that case, students showed more information search behavior except family search source. 3. According to the situation, main and interactive effect of sex and involvement level on perceived risk and information search behavior were significant. In self using purchasing, involvement level had the main effect to the type of information search behavior. But the family search source was the exception Also in gift giving purchasing, they showed the same results. In self using purchasing, main effects of sex and involvement level on perceived risk were significant. Also in gift giving purchasing, they showed the same results, but the socio-psychological risk was the exception.

The purpose of this study was to examine the specific nature of early relationship between infant and father. The subject pool for the study consisted of 42 middle-class infant-father days. Infant's ages were 12 moths to 17 months. All were fullterm babies In order to assess the patterns of infant-father attachment each dyad was videotaped in the simulated Strange Situation of Ainsworth et al(1978). In order to assess the paternal sensiti-vity toward the infant's cue,. each dyad was also filmed for a 3-minute Questionnaire Situation Gratification of the Transition to Fatherhood. Also at home mothers completed a report on infant temperament using the Infant Characteristics Questionnaire. Among 42 infants 48% or 20 were classified as securely attached 38% or 16 as anxious-avoi-dant and 14% or 6 as anxious-resistant Using the discriminant function coefficients for combi-ning the paternal sensitivity scores 83% of the infants were correctly classified as A. B. C The patterns of attachment were not found to be significantly different in the paternal childhood experience for attachment relationship to his own parents. Degree of Difficulty and Gratification groups with respect to infant temperamental fussiness.

The ubiquitous, which is developed for human's convenience, uses the concept of situation awareness that communicates with computer and performs a certain work without user's recognition. In order to collect the information of situation, many devices are required. Also, in the condition of ubiquitous middleware, priority is given to effective controls of various devices. There are many devices for collecting the information of situation awareness such as sensor, RFID, etc. Among them, in the use of RFID, the researcher performed the experiment, in which multiple readers were used depending on the necessity of awareness information, and found the problem of intervention between readers occurring when multiple readers are used. The paper handles the problem of intervention causing from using multiple readers and suggests middleware design module using session manager to solve the problem.
