As fast-speed of aging in modern society has led to increased concern for aging and health improvement of senior citizens, desire about having healthy living-environment has also increased. Living space for senior citizens has to play role of healing for their body feature as well as decrease in mental and psychological function. Color, as important factor that supplements degenerated sense and coping ability caused by aging, it has been revealed through modern medical science that color is effective for making nervous or calming down when it is delivered to one's nerve through sight. The purpose of this study is to suggest basic resource for color arrangement palette of living space and application method by color therapy to improve seniors' mental health by considering psychological and physical features caused by aging. First, consider psychological and physical feature of seniors and color therapy effect through previous research. Second, extract RGB value after selecting color that is helpful for their mental health by using palette from 'Korea Agency for Technology and Standards'. Third, extract other 3 colors that are similar with extracted color from 'NCS 1950 Color System'. Fourth, deduct palette of 3 color arrangement by using 'NCS Navigator' program. Lastly, extract arrangement palette for them by considering difference in visual features, and then suggest arrangement application for each palette through Computer Simulation.

This paper presents the analysis results of dynamics in the billiards game within the frame­work of rigid-body mechanics and a numerical simulation program. The friction exists between the ball and the table bed as well as between the ball and the rail. There are three parts in the dynamic behavior of the ball on the table bed; motion of the ball on the table bed, collision between balls, and collision between the ball and the cushion. During the development of the simulation program, the dynamics problems such as rolling motion and three-dimensional frictional impact motion have been analyzed in detail. The theoretical issues are implemented into a viable graphic simulation program and its efficacy is demonstrated through the experi­mental validation of the billiards game. The resulting analysis results are verified quantitatively and qualitatively using high-speed video camera. Through the experimental tests, it was found that the physical parameters such as coefficients of restitution and friction vary according to the motion variables and corresponding empirical formulations were developed. The simulation and experimental results agree well.

Objective: The aim of this study is developing the navigation radar display of navy ship with ecological interface design (EID) framework. Background: Navy ship radar operator must perform navigation support tasks by monitoring the complex and diverse information presented on the radar display. Current radar display is limited in effective navigation aid and response to an unusual state immediately. It is necessary to develop an effective radar display. Method: Ten navy radar operators performed a series of trials in a low-fidelity radar simulation in which they attempted to solve the problems of current navigation situation. Results: The result demonstrated that the ecological interface's performance was better than the existing radar display on performance time and subjective mental workload. Conclusion: This study expand EID study field to navy ship radar display and confirm ecological display is better than existing radar display in performance time, subjective mental work load. Application: The result of this study may help to improve navy ship navigation radar display currently in use.

The purpose of this paper is to investigate a possibility of applying multimethodological approach for solving a dilemma. The motivation of this attempt is that the two different approaches, the system dynamics and the theory of constraints, resemble each other in having mental models for describing the target system and using graphic tools for representing those mental models. After a brief discussion on the comparison of the two approaches, a combined method applying to the problem of dilemma is suggested. For an experimental example, the proposed approach is applied to the sales and finance conflict on an inventory issue. The study shows that the suggested approach is able to complement each other's drawbacks. Especially constructing a stock-and-flow model and implementing a computer simulation would be very useful for quantifying the system's behavior which is hardly tracked down when applying the theory of constraints alone.

Even after learning electric current, elementary school students have various non-scientific conceptions and difficulties. Because flow of charge is not visible. Also elementary school students do not learn theory but phenomena, so they cannot transfer theoretical perspective to new situation. In this research, we have designed instruction based on PhET simulation visualizing flow of electric charge and applied it to 37 science-gifted students in elementary school for measuring conceptual understanding. As a result, six out of the seven Hake gains of question set are high gain and just one is middle gain because the students have understood the flow pattern of the charge through circuit elements such as light bulbs, wire, as well as battery with PhET simulation and it gives a chance to create various questions spontaneously about electric current. Also they become able to do spontaneous mental simulation without PhET simulation about flow of charges. This research, suggest that developed materials using PhET simulation could be used as not only program for gifted students in elementary school, but also the electrical circuit section in an elementary science curriculum.

This Study discuss exploring normative-prescriptive factors after the themes on Organizational learning categorize two descriptive/explanatory-perspectives, prescriptive/normative dimension. The former would contain information processing model, theory of action, organizing in organization, while Senge's suggestion on Learning Organization may compose the latter. Each perspective is reconstructed and reinterpreted into the causal mapping relationship founded on system thinking and SD. Underlying on the former try to discovery validities of the latter. But this study only put forward the integral-dynamic model of organizational learning without empirical simulation.

Purpose: The purpose of this study was to evaluate the effects of a simulation based clinical reasoning practice program on clinical competence in nursing students. The program was based on the theoretical frameworks of simulation models and experiential learning theory. Methods: The program consisted of eight scenarios which includes three main symptoms (abdominal pain, changes in mental status, dyspnea), for improvement of clinical competencies in nursing students. A nonequivalent control group pretest-posttest design was used for evaluation of the effects of the program. Fifty-two junior nursing students in Y University participated in the experimental group (n=25) or control group (n=27). Critical thinking was measured using a self-administered questionnaire. Clinical judgment and clinical performance were measured by a rater using the Rubric. Descriptive analysis, t-test, Mann-Whitney U, Wilcoxon signed rank test was used for data analyses. Results: Clinical judgment and clinical performance increased in the experimental group, but there were no significant differences in critical thinking. Conclusion: Results indicate that the program developed in this study is a useful strategy to enhance clinical judgment and clinical performance in nursing students. However, the program did not significantly enhance critical thinking disposition, and further study is needed to measure integrated clinical competence including critical thinking skills.
