Scenario-based learning (SBL) has been used in a variety of training situations across different disciplines. Despite its seemly widespread use in construction management discipline, very few attempts have been made to explore its effectiveness and the respective students' learning experience. Using a survey research design, this study aims to investigate students' perceptions on SBL approach in construction management courses. The specific objectives are: (i) to identify the characteristics of a favourable SBL environment, and (ii) to explore the students' learning experience and effectiveness of the SBL approach. The results show that the four characteristics of a favourable SBL environment are: effective team formulation, constant engagement with lecturer, working in a group, and incorporation of motivational incentive for participation. The students really appreciated the opportunities to apply concepts learnt in the lectures in their SBL group work. Also, they perceived that the SBL approach is effective in developing their reflective and critical thinking skills, analytic and problem-solving skills and their ability to work as a team. These findings should facilitate more critical approaches to similar form of teaching methods.

Recently, as mobile paradigms such as telematics or LBS (Location Based Service) have been being more diverse and mobile devices such as PDA (Personal Digital Assistance) or several telematics terminals have been being used more widely, mobile services, for example, mobile geographic information service have been being put more importance by people. In this paper, we propose to adopt S/W and data streaming mechanism as a method to improve performance of mobile geographic information service which is a representative of mobile services based on client-server architecture. The show the effectiveness of proposed methods, we design and implement S/W streaming prototype system and sample mobile geographic information service to be executed on the S/W streaming system.

New transport technologies have been rapidly developed and various transport systems are ready to introduce. However, there no exists effective decision making tools for pre-feasibility studies on transport systems. The pre-feasibility studies should provide reliable solutions about whether a certain transport system is feasible or not by cost-benefit analysis and effectiveness test of enhancing regional economy. This study introduces the smart transport investment/information system (SMARTIS) for supporting decision making with ease, fast and reliable methods. The SMARTIS incorporates travel demand estimates into the process of feasibility studies with automatic data processing methods to give reliable solutions quickly. The SMARTIS is expected to be informative for transit agencies, planners, and operators.

In this paper, we propose a new model for predicting effective Win/Loss in professional baseball game in Korea using machine learning technique. we used basic baseball data and Sabermetrics data, which are highly correlated with score to predict and we used the deep learning technique to learn based on supervised learning. The Drop-Out algorithm and the ReLu activation function In the trained neural network, the expected odds was calculated using the predictions of the team's expected scores and expected loss. The team with the higher expected rate of victory was predicted as the winning team. In order to verify the effectiveness of the proposed model, we compared the actual percentage of win, pythagorean expectation, and win percentage of the proposed model.

Until now most of the leadership studies have been focused to managers having in formal authority. However, in the recent business environment, team member should also demonstrate his leadership. Hence, the purpose of this study has been focused to the team member's leadership and their leadership effectiveness. In this study, we verified how the degree of master sergeant's support can control to moderate the intensity of the team member's leadership behavior. The analysis results were as follows: we have found that team member's issue leadership can effect on positive(+) way on the audience's acceptance to the leader as well as team performance. But the moderating effects of master sergeant's support on the team member's issue leadership and leader acceptance was not significant in terms of statistical point of view. It has also shown even the negative(-) effects of master sergeants's support on the team member's issue leadership and leader acceptance as well as team performance. Through this study, we can understand that the master sergeant's support may impeding the team member's independent leadership.

The purpose of this study is to investigate the friction characteristics of brake pads according to different ratios of $BaSO_4/CaCO_3$. Four brake pads with different ratios of $BaSO_4/CaCO_3$ were manufactured. The friction characteristics of brake pads were tested using 1/5 reduced scale tester. With increasing of the amount of $BaSO_4$ density and shear strength of brake pads were increased and hardness of brake pads were decreased. In effectiveness, the friction coefficient of brake pad was higher and the stability of friction coefficient was better as the ratio of $BaSO_4$ increased. In fade test, friction coefficient of B3 sample used only $CaCO_3$ was decreased rapidly. B1 sample showed a good noise performance without noise generation. The wear resistance of samples were decreased with increasing of the ratio of $CaCO_3$.

In order to match the paradigm shift of a construction company for obtaining competitive edge, it is necessary to introduce newly an innovative educational method in the architectural engineering domain. The objective of this study is to adopt team-based learning, whose effectiveness have been proven in other domains, and to examine its applicability in architectural engineering education. To verify its effectiveness, a questionnaire survey of 39 attendees was conducted at the end of a term. As a result of that, academic achievement of students was higher than that of previous teaching method. In the future, team-based learning adopted in more subjects of the architectural engineering will contribute to improve the academic achievement of students by extension, to raise up the competent practitioners.

Purpose : In a PACS(Picture Archiving Communications System) environment, which is a very important component in a digital medical environment, the compression of digital medical images is a necessary and effective feature. In a current system where JPEG is applied to the compression of medical images, this study is to examine effectiveness and suitability when the JPEG2000, a more advanced compression algorithm for still images, is applied to the compression of medical images. In this thesis, we attempt to address the compressibility for effective clinical usage when compressing medical images, applying the objectivization of clinical evaluation as a function of compressibility. In the experiment al method, the compression was applied at a fixed rate using JPEG2000, and the n the result was compared with compressed images by JPEG. Method : For the performance evaluation, we choose SNR(Signal to Noise Ratio) measurement of an objective evaluation of definition and analyze a subjective evaluation by the ROC(Receiver Operating Characteristic) method. The results of the experiment showed that in the case of JPEG2000 there is hardly any distortion of images, even at high compression ratio(100:1), while regarding noise, the SNR remains around about 40dB, which is also relatively high. Before reading by reference to evaluative materials concerning objective compressed images, it is impossible to apply high compression to images : however, after reading, this can be applied to images that have already existed for some time.
