Characteristic Features of the Behavior and Perception of Evacuees from the Daegu Subway Fire and Safety Measures in an Underground Fire

Abstract In this research study, the authors examined the behavioral characteristics of the evacuees who survived the Daegu subway fire on February 15, 2003, and matters related to evacuation were analyzed through interviews and questionnaires. The authors selected the Daegu subway fire survivors as their research subjects in order to understand human behavior concerning an underground emergency and to obtain ″close-to-reality″ data. Data, with regard to this research, is required in order to develop a method of minimizing life-threatening dangers and provide evacuation safety based directly on those who survived the actual evacuation process in the February 15, 2003 Daegu subway fire. This study found that the various spatial, environmental, and human factors made evacuation very difficult. When the fire broke out, 24.5% of the passengers reacted passively instead of instantly taking evacuation action; there is a statistical difference between the location of the carriage on the train and the factors that influenced each person′s decision to take refuge (x2=34.186, df=15, p=0.003<0.05). The greatest obstacles to evacuees were bad visibility (68.7%) due to smoke, and 93.3% of the subjects did not have significant help from the exit light they saw while evacuating. Finally, only 12% of the survivors evacuated through appropriate escape routes and exits.

A Study on the Electricity Consumption Propensity by Household Members in Apartment Houses

Korea is a country with an exceptionally high energy consumption. For economic reasons, Korean households are forced to save more energy. Korea`s household energy consumption has grown slowly compared to other sectors and household energy consumption per capita is lower than the OECD average. However, its per capita electricity consumption soared and is expected to remain climbing mainly due to the increasing number of one-person households. To establish an effective strategy against a possible electricity shortage, the actual condition survey of electricity energy consumption first needs to be clearly understood. This study adopted both a general survey and a detailed survey of people living in apartment housings and data was collected on electrical appliance use according to individual schedules. Based on these data, the results were used to attempt to analyze electricity consumption patterns resulting from energy using activities of residents and to determine electricity consumption propensity according to each household member`s characteristics in apartment housings.

A Study on the Energy Consumption and Greenhouse Gas Emission of the Detached Houses in Daegu

In the energy consumption of buildings in Korea, the housing sector accounts for 53% of a total energy consumption. Although the researches of energy consumption on the new detached houses and apartment houses have been conducted numerous times, the researches of energy consumption characteristics on the existing detached houses are lack of studies. Thus in this study, the actual condition of energy consumption characteristics on the existing detached houses in Daegu city was examined, and then energy consumption unit and green house gas emission unit was compiled to present a fundamental data for an effective way of reducing energy consumption and greenhouse gas emission in the buildings. The results showed that the energy consumption for heating in the existing detached house was greater than other energy consumption and the heating energy sources were city gas and fuel oil. As the fuel oil consumption got larger, the energy consumption unit and greenhouse gas emission unit became bigger. Based on these results, it will be able to develop a plan for reducing energy and greenhouse gas emission in the existing detached houses in the future.

A Study on Improvement and Effect of Carbon Point Program for Residential Buildings in Daegu

The amount of energy consumption in the buildings is approximately 20% of domestic energy consumption. The Carbon Point Program have been published on reduction of greenhouse gas emission in buildings under the paradigm of `Low Carbon Green Growth`. This study focuses on the effect of `Carbon Point Program` for residential buildings in Daegu. The amount of electricity and waterwork consumption and information of households were investigated to analyse the effect of carbon point program. The samples are situated in Deagu and are apartment in Bukgu and Suseonggu. The emission is analysed by factors of energy resource and household organization between before participating and after participating in Carbon Point Program. The participation type has a difference of voluntary participation in Suseonggu and passive participation in Bukgu. Based on this investigation, average amount of emission was reduced from voluntary participation households but all of them did not. To promote the effect of Carbon Point Program, this study proposes that needing the plans to raise will and activity of reducing carbon and to help participation which have disadvantage against achieving reduction.

The introduction of a USN-based Fire Protection Model: regarding the Seomun Traditional Market in Daegu, Korea

This paper describes how many fire accidents that cause casualties and property loss have been described in newspapers and this has aroused people’s attention to safety. A typical example is the fire that occurred at Seomun Market in Daegu, Korea in December 2005. According to a Fire Department report, the fire caused about 100 million dollars worth of damage. The stores and shops in traditional market places have long played a central role in the transaction of goods and services, however, these markets have been on the decline recently because the stores have been poorly designed and constructed. These markets have not responded to environmental changes either internally or externally, so there is always a potential risk of fire. In order to prevent fires at traditional markets, the Korean government decided to install the U-FPMS (Ubiquitous Computing-Based Fire Protection and Management System) in the Seomun Market Place in order to detect fires. Like this, the materialization of ubiquitous computing, which is capable of communication anywhere is being developed because of the advancement of Information and Network Technology. Such technology provides a better environment for civilization. This paper introduces the U-FPMS and discusses how to make use of ubiquitous computing with regard to fire protection.
