This study investigated problems found with the installation of a descending life line which is one of the compulsory fire escape apparatuses required by the revised "Fire Service Act" of 2006 for multi-use facilities and multistory buildings. It presents an analysis of the causes and improvement details for the problems classified by type of item. To achieve the purpose, the total 367 problem points are indicated. The problems of Installation are unsuitable window glass using the descending life line(34%), required passage device is not attached(23.7%), the installation location is with required operation(20%) and damaged descending life line(20%) were investigated. In particular, the study looks at the stress analysis range for cracking window glass which is required for people to escape in an emergency. People have questioned unsuitable window glass for using the descending life line among the problems with the installation. As a result of stress analysis, window glass thickness of the place where the descending life line is installed must be 3 or 6 mm. In addition, this study indicates substantial improvement measures for installing the descending life line so I will actually be used as a fire escape apparatus to protect human lives, and not just to formally meet the Fire Service Act.

Tourism motivation and involvement are important variables influencing visitors satisfaction. The study aims to identify the factors influencing visitors' satisfaction. Particularly, the study examine the moderating effects on tourism involvement between tourism motivation and visitors' satisfaction. Data were collected from 430 usable questionnaires among visitors of Gigisi local festival. Results of a factor analysis yielded three dimensions of tourism motivation which are family and local food, recreation and escape, and social factor. Results show that social factors among three dimensions of sense of community have significance for visitors satisfaction. And tourism involvement has a negative interactional effects as a moderator between recreation and escape motivation and involvement. It means that even though higher recreation and escape motivation, less likely to have visitors satisfaction if visitors have higher involvement in local festival. It was suggested that tourism motivation and involvement should be considered in local festival management and policy.

When fires occur in high-rise buildings, it is difficult to determine whether each escape route is safe because of complex structure. Therefore, it is necessary to provide residents with escape routes quickly after determining their safety. We propose a method to measure the visibility of the escape route due to the smoke generated in the fire by analyzing the images. The visibility can be easily measured if the density of smoke detected in the input image is known. However, this approach is difficult to use because there are no suitable methods for measuring smoke density. In this paper, we use principal component analysis by extracting a background image from input images and making it training data. Background images and smoke images are extracted from images given as inputs, and then the learned principal component analysis is applied to map of as a new feature space, and the change is calculated and the visibility due to the smoke is measured.

North Korean fugitives is one of various nominations referring to the North Koreans who have secretly crossed the territorial border of their country. It is a new terminology that huts gained wider usage in our society as we entered the 1990s. North Koreans list various motives for escaping their county, such as food shortage and disillusionment of belief in the system. Most of the forced repatriation of North Korean escapees takes place in China. The purpose of this study examines the family knife of female fugitives from North Korea in order to provide pertinent alterntives which are needed to secure basic human right of the female fugitives and enable them to keep stability of their family lives and to adapt themselves into new socio-cultural circumstances in China. For this, the preliminary survey performed to examine the demographic characteristics on the female fugitives; to find out the incentives and channels of their escape out of North Korea; to investigate what types of family life and family relationship they manage in China; to grasp their problems and need of family life in adaptation into Chinese society. The specific questions for grasping the general characteristics of the female fugitives are composed of age, education level residential district in North Korea. In order to find out main causes and influential factors of their escape from North Korea, the following questions are included: what the most important incentives and motives are; the frequency of escape; and whether they discuss their escape with their family or not. The questions to find out their present actual life situations in China are about difficult things to adjust in China, family life, relationship with husband, and their conversational diction, the degree of their mastering the chinese language, the degree of their adaptation to chinese way of living, and so forth, which reveal to what extent they are adapted themselves to new cultural situation in China. This study collected the data through face-to-face personal interview from July to October, 1999 Yenben province along the China-North Korea border. Data from 202 female fugitives were used in final analysis. This study uses the SAS PC program for windows, Ver, 6.12 to analyze the data such as the distribution of frequency, percentage, mean and so on. The results from this analysis are follows; the most principal motive of North Korean women's escape to china is to eat to live because of famine. Concerning the year when the fugitives escape from North Korea, all of the interviewees haute escaped since 1990. After escape their continual contact with their family in North Korea, 81.7% of the respondent have not been in touch with their family. The main reasons for their not contacting with their family in North Korea are that it is not helpful although they contacts with their family. Female fugitives from North Korea have difficulties in life. They have rather stable relationship to their husband, but they have experienced difficulties in other aspects of family life. Their main difficulties are largely from their relationships to husbands'family members, and from the problems relate to their family in North Korea, and their children. Based on this study, further research has to present supportive policies that help North Korean female escapees live without being deprived and protect their human rights. And the development of practical program to help their efficient social adaptation has to be continued without stop together.

The aim of this study is to investigate the direction of improvement of safety experience education through the analysis of the evacuation time experiment. For the study, test subjects were divided into groups of similar body size and weight. The test subjects were directly experienced four evacuation devices, and the experience time was measured. As a result of the analysis of the total time from the installation of the evacuation device to the escape, the time was measured in the order of Descending Life Line-Tilt-Down Rescue Line-Vertical Escape Chute-air safety mat. In the case of evaluating the evacuation time using evacuation mechanisms, the evacuation time was measured in the order of air safety mat-Tilt-Tilt-Down Rescue Line-Descending Life Line-Vertical Escape Chute. In the first and second experiments of the Descending Life Line, time differences were observed. The escape time using the Descending Life Line was reduced in the second experiment than in the first experiment. As shown in this result, education through experience has shown that behavioral confidence and time can be managed. The conclusion of this study is that the goal of safety education is to minimize human life and property damage. Therefore, in order to bring this effect to more people, it is necessary to make efforts to keep self-safe through experiential education.

In a SCH(separate confinement heterostructure) QW(quantum well) laser, we calculated the optical gain, the differential gain and recombination current in the QW and derived the bulk carrier density in the SCH region as a function of the QW current by using the analytical capture escape model. Based upon above relations, we found the optical gain and the differential gain correspond to the ratios of carrier and current injected into the QW.

In order to investigate water flow characteristics after inrushing in process of karst tunnel excavation, numerical simulations for five case studies of water inrush from the tunnel floor are carried out by using the FLUENT software on the background of Qiyueshan high risk karst tunnel. Firstly, the velocity-distance curves and pressure-distance curves are drawn by selecting a series of probing lines in a plane. Then, the variation characteristics of velocity and pressure are analyzed and the respective optimized escape routes are made. Finally, water flow characteristics after inrushing from the tunnel floor are discussed and summarized by comparing case studies under the conditions of different water-inrush positions and excavation situations. The results show that: (1) Tunnel constructors should first move to the tunnel side wall and then escape quickly when water inrush happens. (2) Tunnel constructors must not stay at the intersection area of the cross passage and tunnels when escaping. (3) When water inrush from floor happens in the left tunnel, if tunnel constructors meet the cross passage during escaping, they should pass through it rapidly, turn to the right tunnel and run to the entrance. (4) When water inrush from floor happens in the left tunnel, if there is not enough time to escape, tunnel constructors can run to the trolley and other equipment in the vicinity of the right tunnel working face. In addition, some rescuing equipment can be set up at the high location of the cross passage. (5) When water inrush from floor happens in the cross passage, tunnel constructors should move to the tunnel side wall quickly, turn to the tunnel without water inrush and run to the entrance. (6) When water inrush from floor happens in the cross passage, if there is not enough time to escape, tunnel constructors can run to the trolley and other equipment near by the left or the right tunnel working face. The results are of important practical significance and engineering value to ensure the safety of tunnel construction.
