  • A novel approach to estimate the real time moving trajectory of an object is proposed in this paper. The object position is obtained from the image data of a CCD camera, while a state estimator predicts the linear and angular velocities of the moving object. To overcome the uncertainties and noises residing in the input data, a Kalman filter and neural networks are utilized. Since the Kalman filter needs to approximate a non-linear system into a linear model to estimate the states, there always exist errors as well as uncertainties again. To resolve this problem, the neural networks are adopted in this approach, which have high adaptability with the memory of the input-output relationship. Kohonen Network(Self-Organized Map) is selected to learn the motion trajectory since it is spatially oriented. The superiority of the proposed algorithm is demonstrated through the real experiments.

  • A control system design based on coupled nonlinear oscillators (CNOs) for a self-organized swarm system is presented. In this scheme, agents self-organize to flock and arrange group formations through attractive and repulsive forces among themselves using CNOs. Virtual agents are also used to create richer group formation patterns. The objective of the swarm control in this paper is to follow a moving target with a final group formation in the shortest possible time despite some obstacles. The simulation results have shown that the proposed scheme can effectively construct a self-organized multi-agent swarm system capable of group formation and group immigration despite the emergence of obstacles.

  • As knowledge has been recognized as a new resource in gaining organizational competitiveness, Knowledge Management (KM) is suggested as a method to manage and apply knowledge for business management. KM research, however, has focused on identifying, storing, and distributing the transaction-related knowledge in an organization. There has been little research on applying the knowledge to decision-making or strategy development that is the main task of business management. The application of knowledge to decision making has higher impact on organizational performance rather than just the knowledge management for process transaction. In this research, we suggest System Dynamics (SD) for the knowledge-based decision-making. Based on the modeling method of SD, we can translate partial and implicit knowledge resident in individual's mental model into organized explicit knowledge. The simulation test of the organized knowledge model enables decision-makers to understand the structure of the target problem and its behavior mechanism, which facilitates effective decision-making. We will compare the proposed method and other KM methods and discuss this research based on the application case to a real telecommunication company.

  • This study makes sense for suggesting efficient spatial design education. The reviewer has been responsible for the 'spatial design' curriculum for six years and has established it as a case of four stages of education. The curriculum falls into a 3-year professional university. In conclusion, in order to effectively educate the spatial design, it is a place where the space is actually present, and the learners will be able to make a destination where the learner can often experience it. It is recommended that teams be organized and organized. In addition, if you can apply a variety of design methodologies, The learners will be able to experience a rich space design process.

  • A novel biomaterial capable of incorporating biotinylated biomolecule has been synthesized. Our strategy is to biotinylate one-dimensional electroactive polymers and use a bridging streptavidin protein on Langmuir-Blodgett (LB) organized films. These copolymers are derivatized with long alkyl chains and biotin moieties to bind, respectively, to the hydrophobic surface and the biotinylated species, through the biotin and streptavidin complexation. We utilize the polymer assembly approach to attach a signal transducing biomolecule biotinylated phycoerythrin (B-PE) into this novel biomaterial by binding the unoccupied biotin binding sites on the bound streptavidin (4 sites total). The pressure-area isotherm of the protein injected monolayer showed area expansion. A characteristic fluorescent emission peak at 576nm was detected from the monolayer transferred onto a solid substrate. These observations demonstrated the promise of the organized thin polymer assemblies for their application to the sensor system.

  • In recognizing knowledge as a new resource in gaining organizational competitiveness, knowledge management suggests a method in managing and applying knowledge for improving organizational performance. Much knowledge management research has focused on identifying, storing, and disseminating process related knowledge in an organized manner. Applying knowledge to decision making has a significant impact on organizational performance than solely processing transactions for knowledge management. In this research, we suggest a method of knowledge-based decision-making using system dynamics, with an emphasis to strategic problems. The proposed method transforms individual mental models into explicit knowledge by translating partial and implicit knowledge into an integrated knowledge model. The scenario-based test of the organized knowledge model enables decision-makers to understand the structure of the target problem and identify its basic cause, which facilitates effective decision-making. This method facilitates the linkage between knowledge management initiatives and achieving strategic goals and objectives of an organization.

  • This study was conducted to identify an initial clinical experience of EMT students, so to better understand their' experience in clinical training. The subjects were 30 EMT students of C department of Emergency Medical technology in C city, who were demonstrating at the emergency room in C, T, S, W city. This study was approached by phenomenological method, collected data were analyzed by Colaizzi's method. the results were as a follows. From the protocol, significant statements were organized into 34 formulated meanings. from the formulated meanings, 21themes were identified, organized into 8 theme clusters, and then categories. EMT students got experienced 'tension resulting from new situation', 'fear in contacting with patients', 'lack of knowledge and skill', 'confidence feeling from being adapted', 'facing up to Paramedic role', 'experience of death' and 'stress'. The results of this study are to use as basic data for students attending clinical experience for the first time.

  • In this study, a new technique for detecting near miss using 4M risk assessment method is suggested. Until now, the safety education with instances of near miss has just been progressed in most industrial settings, without any systematic guideline. By menas of appling 4M risk assessment method, the organized technique, which could effectively manage the fundamental prevention of industrial accident in advance, is developed. The organized technique of near miss-management suggested in this study will take an effective role in basically expanding the application of risk assessment method, as well as in contributing the activity of zero-accident as a safety guideline in hazardous workshops.

  • Recently, the birth rate of congenitally anomalic babies is increasing in Korea. But there are few studies and articles in nursing field. So nurses are having difficulties in caring those mothers. This study is to reveal experiences of the mothers with congenitally anomalic babies. Subjects were six and data were gathered by interviews. Data were analyzed by Giorgi's method. Mother's responses were organized into five categories-shock, sadness, expectation, attribution and loss of confidence on future pregnancies. Loss of confidence on future pregnancies were categories which were not found in foreign articles. Based on the result of this study, author recommend that another studies which deal only same anomaly will be done, and genetic counseling system will be organized in hospitals.
