  • This is a descriptive study on quality of life(QOL) and related factors of ostomates to provide a basic data for development of nursing interventions. The subjects were 110 ostomates who were members of the Daegu or Daejon branches of the Korean Ostomy Association. Data collection was performed between March 1st and April 6th, 1998. Measurements of QOL, self-care, family support, self-esteem, and hope were used as the study tools. Data were analyzed with the SAS program by using t-test, ANOVA Pearson correlation and stepwise multiple regression. The results are as follows : 1) The score on the QOL scale ranged from 97 to 226 with a mean of 164.53($\pm$28.29). 2) The score of QOL on the general and ostomate-related characteristics showed significant differences according to monthly income, monthly participation in ostomate meetings, combined treatments after operation, types of evacuation management, problems of ostomy, help in caring for the ostomy, length of time since ostomate surgery, and presence or absence of readmission after discharge. 3) There were significant positive correlations between quality of life and other factors : self-esteem(r=0.7107, P<0.001), hope(r=0.6584, P<0.001) family support(r=0.6191, P<0.001), perception of health condition(r=0.6017, P<0.001), and self-care (r=0.2286, P<0.05). 4) The variables that affected the quality of life of the subjects were self-esteem, level of family support, perception of health condition, monthly participation in ostomate meetings, combined treatments after operation, monthly income, level of hope, and age in that order. The variance of quality of life was $R^2$=77.20 percent by calculating the sum of those variables. In conclusion, it is necessary for nursing intervention to promote self-esteem, family support, and hope in the care of ostomates in order to improve QOL.

  • With regard to smoke control system, the design guidelines of smoke exhaust for accommodation and smoke control for evacuation stairs and vestibule has been proposed domestically, but after reviewing the applicability to modern buildings that tend to be larger, higher and complex, a smoke control system according to domestic design guidelines might have difficulty in securing the safety from smoke in a fire. Therefore, it is necessary to adopt the performance-based design of a smoke control system that can enhance the safety and integrate the smoke control functions and design depending on the characteristics of fire and building structure in the case of fire in a large, high-rise, and complex building. This study analyzed the domestic design guidelines of a smoke control system and this paper proposes the part requiring improvement, and examines the legal system and guidelines on performance-based design of smoke control system in foreign countries.

  • Seoul, a mega city, contains many features of the modern city. When the disaster or emergency occurs in Seoul, the place for shelter is required for evacuation urgently. There are currently the numbers of shelters in Seoul City, which can hold the twice more capacity of population of Seoul. However, the population distribution fluctuation in the day and the night needs to be considered. Therefore, in order to analyze the actual capacity of shelter, it is necessary to consider the dynamic characteristics of population distribution in the metropolitan area. In the study, the substantial accessibility and the capacity of shelters in Seoul were analyzed by the floating population data of the metropolitan area. The accessibility of shelter was investigated through a network analysis that includes the pedestrian road data, while the capacity of shelter was analyzed by the local differences of daytime population distributions. Finally it was possible to identify the vulnerable areas on the basis of the distribution of shelter in the region.

  • This study is focused on the numerical predictions for different smoke-control ventilation modes for the subway fire. Smoke-control ventilation mode in the domestic platform is that exhausting for the smoke detected zones while supplying air or stopping any ventilation for other zones in the platform. Three cases of smoke control ventilation modes are considered. First and second case are present running smoke control mode in Korea. The third is that smoke-control ventilation fans equipped in the platform are operated in first 4 minute(platform evacuation time, NFPA130) since then the fans equipped in the platform are stopped and the fans equipped in the tunnels are operated. Distributions of heat, carbon monoxide and visible range are compared at a height of 1.7m(passenger breath/sight height) above the platform. The numerical results show that air supply fan operation in the platform causes the smoke disturbance and a rapid spread of the smoke. The switch-operation with fans in both the platform and tunnel are better than operation with only platform fans in smoke rejection efficiency.

  • The purpose of this study was to evaluate the effects of routine haecho bibimbab (boiled rice with assorted seaweed mixtures) consumption on the bowel habits in humans. Forty free-living adults (female 38, male 2) participated in this study (mean age $41.2\;{\pm}\;7.5$). After a baseline survey on general characteristics, life style and dietary habits, the participants were asked to consume haecho bibimbab during two-week period for lunch. Habitual bowel movements were checked out every day by a questionnaire and nutrient intake was estimated by a 24-hour recalls before and after the study. After 2 weeks of clinical trial, the bowel habits had improved. Haecho bibimbab increased the number of bowel movements, changed hard stools into softer ones. It also lessen the sense of incomplete evacuation, and abdominal pain during defecation, increased water intake (p < 0.001) and improved gastrointestinal problem. The participants believed that haecho bibimbab was effective in improving their constipation symptoms and bowel habits (p < 0.01). Routine haecho bibimbab consumption tended to increase especially vitamin A, E and folate intake (p < 0.01). The present findings suggest that routine seaweed-based lunch meal (haecho bibimbab) consumption may improve bowel habits without side effects.

  • Today, high-rise buildings expected to meet various needs and improve the quality of frequency of fire and the potential risks are increasing. In particular, the fire spread risk in the vertical direction is increasing. As a result there is a problem with delays in the evacuation time of occupants. To overcome this problem, there is a need to consider the structure of the building and develop a system for the early detection of fire by applying a fire alarm system according to the risk ranking. Therefore, this paper describes the vertical fire spread characteristics of a multistory double-skin and stairs structure with risk. The data were compared with that from the national and international fire alarms as well as with. smoke density, smoke detectors, visibility, and CO concentration using FDS. A fire alarm system for each structure is proposed.

  • In the case of a medium length road tunnel, the installation of a smoke control facility is not mandatory so users can suffer considerable injuries if a fire breaks out. Therefore, this study analyzed the high-temperature air and toxic gas generated by fire proliferating with time when a smoke barrier is not installed and when the installation interval is 100, 150, 200, and 250 m through 3-dimensional numerical analysis, evacuation simulation, and Quantitative Risk Assessment Methodology targeting the medium length road tunnel. As a result, the diffusion of the high-temperature air and toxic gas occurring from the a fire was delayed when the smoke barrier was installed in a medium length road tunnel compared to that when it was not installed. In addition, when the installation interval of a smoke barrier was 100m and the numerical analysis target was 100m, the diffusion of high-temperature air and toxic gas generated by the fire was delayed more than in the other cases, which was most suitable for tunnel users to evacuate.

  • This study was conducted to examine the performance in the space for a single alarm type detector installed in a single house. Three types of houses were used, including two types of one-story and two-story houses. A computer simulation program was used to predict the sound pressure level in response to the occurrence of an alarm sound in a residential space. The characteristics of the sound source applied to the simulation were directly measured and used as input data. As a result of simulation, it was found that the sound pressure level in the kitchen and living room generally met the standard when the alarm sound of the detector occurred. However, the sound pressure level in the bedroom was predicted to be at least 20 dB (A) lower than the American Fire Protection Association standard of 75 dB (A). Therefore, a plan should be prepared to maintain a sufficient sound level in the bedroom space inside the house, and efforts will be needed to ensure safe evacuation in case of fire by establishing relevant standards.

  • Julpyun(traditional Korean rice cake) was prepared by adding silkworm powder(SP) in the ratio of 0%, 3%, 6%, 9% of rice flour, and tested by proximate composition, sensory evaluation, chromaticity and rheological properties. In proximate composition, as the SP increased, amounts of moisture, crude protein and ash increased proportionally. In sensory evaluation test, 6% SP added Julpyun showed the highest score in color, Julpyun added with 3% SP gave the strongest flavor. From the scores of taste, texture and overall quality, 3% SP added Julpyun was evaluated as the best. In rheometer test, hardness increased as the amount of SP increased. Gumminess and brittleness tended to decrease as the ratio of SP increased and 3% SP added Julpyun showed the high value in them.
