BPMS(business process management system) facilitates defining new processes or updating existing processes. However, processing of exceptional or nonroutine task requires the intervention of domain experts or introduction of the situation specific resolution process. This paper assumes sufficient amount of business process exception handling cases are stored in the process repository. Since the retrieval of the best exception handling process requires a good understanding about the exceptional situation, context awareness is an important issue. To facilitate the understanding of exceptional situation and to enable the efficient selection of the best exception handling process, we adopted the 'situation variable' and 'decision variable' construct. A case example for exception handling in the e-commerce delivery process is provided to illustrate how the proposed construct works. Application of the C5.0 algorithm guarantees the construction of an optimum search tree. It also implies that an efficient search path has been identified for the context aware selection of the best exception handling process.

It's a shame one of the famous places of Busan is the underground shopping area on the decline gradually. The reason why we developed this application is to provide information of the desired product and store for other residents as well as Busan residents. As a result, we expect a revival of underground shopping area. The main features of the application are to provide the location of shops and the information of products. In addition, it provides information of shops around me to utilize of location-based-service. We studied the possibility of win-win situation between offline stores and online through this application.

Korea has more than 2,000 fires and more than 2,000 casualties every year. This study takes measures to facilitate the incorporation of 119 fire trucks by judging vehicles or standing signs using real-time image reading YOLO5 before the fire trucks arrive at the fire site. It is possible to shorten the time to extinguish a fire by photographing a fire site, transmitting the situation of the site, and analyzing the components of smoke to determine the type of fire. As a result, it is expected that it will be able to minimize casualties by keeping the golden time.

This study represents a fundamental research for a passenger-ship escape guidance system that is a ship-borne agent, and it is for the support of escape decision-making by providing accurate maritime safety information in real time. We conducted a passenger escaping experiment on a training ship, SAEYUDAL, using the situation-aware escape guidance system, which has been developed for on-board application based on products for buildings. It is shown that the system contributes to the shortening of the escape duration and the dispersion of the escaping persons by generating and guiding the safe escape routes which dangerous areas are considered. From the experiment on ship's heeling condition, it is revealed that the heeling angle is linearly related to the escape duration. Therefore, this study shows that the shortening of the escape duration enables a safe and rapid mustering that is the most important process under emergency and appropriate incident responses to minimize loss of lives.

Interesting education which utilizes cyber visual and audio multimedia effects, we regard it as a very effective education but those programs are not prepared yet. So, the purpose of this research is to provide a new direction for cyber fashion education with the use of avatars as the multimedia factor to increase student's interest and understanding. First, we investigated the present situation of fashion cyber education and the present avatar usage situation online, and also we searched literature and the internet to investigate the general theory of design. Second, we used Adobe photoshop 7.0 to make avatars, then, we used Macromedia Flash MX to design the avatar on our web site, and to make it look more realistic. According to the research results, cyber fashion education is usually used as marketing in certain areas, and for middle school, and high school students it is mainly used as text and lecture videos. When searching for fashion sites that use avatars, we found that most fashion shopping malls use them. Because avatars can give visual effects and also increase interest and fun, they can increase concentration and understanding and can be effective in fashion cyber education.

Tri-phasic pulsatile flow is the general flow pattern of human circulary system. In emulating the various situation of cardiovascular system, it is essential to make tri-phasic source flow. To emulate tri-phasic pulsatile flow, we used electro-hydronic style LVAD(Left Ventricular Assist Device) with glass phantom and rubber tube. We have selected control parameters and examined the changing effect of each parameter by using Doppler ultrasound. In this experiment, it was shown that the distal compliance and the break time were the major factors to form tri-phasic flow. The results make it possible to emulate and explain the various situation of human vascular system. In this point, this results will be an useful method in the clinic application.

It has been almost 20 years since Korea has started the research of school facilities, but there has not been any form of organized information or studies done about such a trend of the research. In this respect, this research places its focus on categorizing 44 policy studies initiated and proceeded by different organizations for last twenty years(1983-2004) and 186 volumes of the research about education facility plans and projects released by journal of Architectural Institute of Korea and journal of Korean Institute of Educational Facilities in 17 subjects of this study. It also concentrates on organizing data based on different levels of schools and periods of time as well as understanding the trend. The result of this research is followings. Considering every volume of the paper and the subjects that have previously been treated in those papers, the trend of this study is divided into the first stage of research period(1983-1993), the second stage of research period(1994-2001), and the third stage of research period(2002-present). Of all the papers, there has been the most number of papers objecting elementary schools(110 volumes, 56.1%), and most of them focused on space formation, size, and the present situation of utilization of each classroom in elementary schools. In the meantime, the studies about educational information, application of the media, space formation and size under teachers'consent, two-dimension types, a design of outdoor space(including gardens), the present situation of utilization, remodeling of school facilities, an evaluation of space and recognition-awareness analysis have been mainly done since 1995. Such a result mentioned above provides a sense of understanding about a level of studies about education facilities in our country, and as a basic source for future guidelines of studies and contents, in my personal opinion, it contains a high level of application.

Tsunami is a frightful natural disaster that causes severe damages worldwide. To minimize the damage, South Korea has built a tsunami warning system and designated evacuation sites in the east and south coasts. However, such countermeasures have not been verified whether they are adequate to minimize casualties since tsunami rarely occurs in South Korea. Recently, due to increasing earthquakes in the west coast of Japan, the likelihood of South Korea entering the damage area of tsunami rises; thus, in this paper, we develops a simulator based on Unity game engine to simulate the evacuation from tsunami. In order to increase the fidelity of the simulation results, the simulator applies a tsunami simulation model that analyzes coastal inundation based on cellular automata. In addition, the objects included in tsunami evacuation, such as humans, are modeled as an agent model that determines the situation and acts itself, based on the discrete-event system specification (DEVS), a mathematical formalism for describing a discrete event system. The tsunami simulation model and agent models are integrated and visualized in the simulator using Unity game engine. As an example of the use of this simulator, we verify the existing tsunami evacuation site in Gwangalli Beach in Busan and suggest the optimal alternative site minimizing casualties.

This research was carried out to develop a program that would promote children's creative thought processes and also to ascertain the effect on their development. The creative thought program consists of three stages : at the first stage, information for the development of the program was gathered and the theoretical basic model established. Considering Divergent and Feeling Factors, the program was planned based on the William's educational curriculum as it was applied and tested in an actual life situation. At the second stage, in order to formulate an activity plan for the creative thought program, William's activity plan was analyzed. At the third stage, the activities which would be applied to the creative thought program in the actual situation were considered with teaching strategy, activity arena and creative thought factors. In conclusion, according to these research results, children's creative thought programs should not just promote Divergent Factors or limited areas of activities, but other activities which include Feeling Factors should be planned and more diverse creative thought programs developed. To design an education program that encourages efficient creative thought, various teaching strategies in creative thought education need to be developed. Teacher training for current teachers should be conducted and parents who have the most direct influence of their children - be made aware of the creative thought process in children. It needs to be stated that this research on creative thought programs is not a complete program: it needs to be further adjusted and supplemented. As development of the tools to evaluate Feeling Factors objectively and the application on the program due to insufficient time, a more continuous application of the program and further research and evaluation of its effects are required.

In order to model the Group Technology Problem three formulations are used, that is, generally the following formulations are used: (1) Matrix formulation, (2) Mathematical programming formulation, (3) Graph formulation. In the case of Matrix formulation, it is difficult to discribe the situation using the multi-job machine. But this paper proposed the model of Group Technology using the multi-job machin, taking the method of making practical application of principle of similarity coefficient.
