Fire scene is mostly destroyed by the flames but fire fighter's fire suppression and rescue activities also destroys a substantail portion. Structures and furnitures which has already become weaken can be easily damaged. Or when structures built up by moving to another location, it's very hard to restore the original state. Also if it is restored, the object has no evidence that it has existed. In all scenes, the scene can't be preserved when quick extinguishment, rescue activities and preventation of fire spread is needed. On this paper, it reviewed the notes about the possibility of field damage by fire suppression and rescue squad's activities. Also it has reviewed the notes how to minimize the field damage by putting out fires and rescue activities by observing the precautions. The reviewed information will help to make guidelines for preserving the scene. By this, it is expected to make a field study exactly by collecting more valid evidence.

This study was performed to propose measures to improve and secure safety in the scene activities of firefighters. First, the majority of firefighters thought that working environment and equipment in fire station were inadequate for perforeming work tasks safely. Second, influential factors threatening safe scene activities mainly arose externally such as insecure working conditions of firefighting or emergency scene. Third, improvement in working environments was pointed out as the most urgent issue to secure safety. Firefighters recognized the expansion of field workforce in system, personnel management and the foundation of hospitals for firefighters hospital in working environment, and the development and distribution of safe equipment and change and inspection of air respirator facepiece on regular basis in equipment as urgent issues to be improved.

In this study, a normative script was designed for service design of coffee shop based on user's current and expected script. 1) Activities contained in current and expected script were identified. 2) High frequency activities were selected from current and expected script. Then they were combined and sorted by scene. 3) Importance of the integrated scenes and activities was assessed. 4) According to certain rules, unnecessary activities were deleted, or excluded as optional activities. Then, the remaining activities were classified by scene and listed in order to complete one normative script. Each activity belonging to each scene became a service encounter. Scenes consisted of 'Entering', 'Settling', 'Ordering', 'Waiting for drinks', 'Receiving drinks', 'Spending time drinking beverages', 'Go to the toilet', and 'Get out'. There were 2 activities in 'Entering', 6 activities in 'Settling', 11 activities in 'Ordering', 2 activities in 'Waiting for drinks', 4 activities in 'Receiving drinks', 6 activities in 'Spending time drinking beverages', 3 activities in 'Go to the toilet', and 4 activities in 'Get out'. Specific points were discussed along with these results, and the significance and limitations of the study were added at the end.

An HDTV frame has 4~6 times more pixels than a DTV frame. In order to encode the HDTV image in real time, parallel processing architectures have been widely used in many HDTV codec developments. That is, an HDTV Image is divided into several subbands and each subband is encoded in parallel using some DTV level encoders. In this paper, we adopt an HDTV codec architecture which divides an HDTV frame into 4 subbands and propose a new scene change detection algorithm using local variance. In addition, a new adaptive multichannel rate control scheme which allocate target bits adaptively to each subband of the HDTV image based on the activities of subband images is suggested in this paper. The activities of subband images are calculated at scene change detection part and reused at the adaptive rate control part. The simulation results show that the proposed scene change detection algorithm detects the scene change of HDTV video very accurately. Also the suggested adaptive multichannel rate control scheme shows better performance than the rate control method which allocates target bits equally to each subbands of the HDTV image.

Standard Incident Command System in Korea is that Incident Command System for Emergency Rescue Operation, which is commanded only by Fire Fighting Agencies. However, in the event of a disaster such as the flood, storm, or landslide disaster, there are many disaster response activities performed by the General Public Officers at the disaster on-scene. Yet, there isn't an Natural Disaster Command System for the General Public Officers in Korea. Thus, we have studied the response activities needed cooperation among agencies and proposed some considerations of the Natural Disaster Command System for General Public Officers. The system will be useful to response and recover disaster rapidly, seamlessly, and cooperatively among General Public Officers and the related agencies.

Hypertext raises question to general assumptions about our conventional conceptions of education. In this essay, three kinds of learning-models are presented by the application of "writing" hypertext literature to the English education of the elementary school. These models, which I call the "scene-centered" system, give knowledge to learners in non-linear, non-sequential structure. The term "scene" is a single concept or idea composed of a single sub-text, which is to be made by the group of students. This system is focused on the collaborative composition of students. Students, by generating sub-texts and connecting texts, perform the educational activities to expand the source text. The "scene-centered" system is, to put it into a Barte's term, a "writerly text." But in order to "write," "reading" should be accompanied. So, this system is a learning model in which writing and reading are carried on simultaneously. In all the process, students play a role of multi-user, with three access rights: read, write, and annotate. So, students making use of hypertext systems will act as reader-authors. And teachers will take the new role in collaborative writing environment. No longer the central authoritarian evaluator, they will become consultants, co-writers, coaches of their students.

Human Emotion Recognition is an exciting topic that has been attracting many researchers for a lengthy time. In recent years, there has been an increasing interest in exploiting contextual information on emotion recognition. Some previous explorations in psychology show that emotional perception is impacted by facial expressions, as well as contextual information from the scene, such as human activities, interactions, and body poses. Those explorations initialize a trend in computer vision in exploring the critical role of contexts, by considering them as modalities to infer predicted emotion along with facial expressions. However, the contextual information has not been fully exploited. The scene emotion created by the surrounding environment, can shape how people perceive emotion. Besides, additive fusion in multimodal training fashion is not practical, because the contributions of each modality are not equal to the final prediction. The purpose of this paper was to contribute to this growing area of research, by exploring the effectiveness of the emotional scene gist in the input image, to infer the emotional state of the primary target. The emotional scene gist includes emotion, emotional feelings, and actions or events that directly trigger emotional reactions in the input image. We also present an attention-based fusion network, to combine multimodal features based on their impacts on the target emotional state. We demonstrate the effectiveness of the method, through a significant improvement on the EMOTIC dataset.

Accidents and terrorist acts that utilize explosives have a great influence on society and thus require a prompt investigation for the arrest of the culprit. However, such investigations are often met with difficulties due to the vastness of the crime scene, restrictions on approaching the scene, fragility of the evidence, complexity of investigation, and the lack of expertise. In spite of such facts, scientific investigation regarding explosives have not been widely studied in Korea. Therefore, the focus of this research primarily concerns the effective scientific investigation methods in cases of accidents that involve chemical explosives. Although the a systematic investigation method is at the heart of scientific investigation in cases of explosive accidents, it is only at its rudimentary stage. Therefore, in this research, a systematic investigation method is put forth for the 'scene investigation, the documentation of the scene, and the collection and processing of evidence. Further, I have set forth a 'scene investigation check list' the ensure a thorough scene investigation and to promote an exhaustive evidence collection that would guarantee the admissibility of such evidence in court. The above efforts were aimed at simplifying the currently complicated investigation system. 1) In the future, a guidebook that can be generally applied to accidents involving explosives in Korea ught to be produced, a continual systematic education and integrated training excises for investigators ought to be established, laws that require additives in explosives ought to be instituted so that the type, components, and source of explosives can be identified, and lastly, a database that contain information on former explosion accidents, trends, and techniques of criminal activities that involve explosion accidents should be compiled.
