The purpose of the weapon live test during the phase of development is to provide essential information to decision makers that verify and validate the performance capabilities of weapons. Due to varying allocation and high variance of test resources with an increase in the weapon system's capability, the test environment can get highly complex, which can lead to a decrease in the reliability of test results. This issue can be addressed by applying a decision support system that provides various timely information collected by resources during the test process. The decision support system can be designed by applying the concept of digital twins, that are defined as digital replicas of components, systems and processes. This paper describes a design methodology of the decision support system that consists of digital models and service functions using digital twin architecture. A case study illustrates the feasibility of the proposed methodology in supporting the weapon live test process.

We employed a hierarchical document classification method to classify a massive collection of electronic medical records(EMR) written in both Korean and English. Our experimental system has been learned from 5,000 records of EMR text data and predicted a newly given set of EMR text data over 68% correctly. We expect the accuracy rate can be improved greatly provided a dictionary of medical terms or a suitable medical thesaurus. The classification system might play a key role in some clinical decision support systems and various interpretation systems for clinical data.

This study aims to find out the influence of the intolerance of uncertainty on entrepreneurial intention by focusing on the start-up support system awareness. While most of existing studies focused on the positive psychological variables and individual environmental characteristics influencing on the entrepreneurial intention, this study has taken a look at the influence of the intolerance of uncertainty as the psychological variable to the entrepreneurial intention to negatively act on the entrepreneurial intention. As a result of the analysis, the intolerance of uncertainty under the control of entrepreneurship and gender is shown to have the negative (-) influence on the entrepreneurial intention and has high level of recognition on the start-up support system perception, and the start-up support system perception is confirmed to have positive (+) influence on the entrepreneurial intention. And, it also indicates that, with respect to the influence of the intolerance of uncertainty on the entrepreneurial intention, the start-up support system perception has the partial medium effect. Following this result of the study, it provides following indications: First the existing studies on the entrepreneurial intention had not covered the intolerance of uncertainty but it is confirmed as the psychological variable with negative influence on the entrepreneurial intention. Second, it is feasible for the preliminary start-up businesses may turn the fear on start-up failure into positive entrepreneurial intention with the start-up support system perception as the leading vehicle. And, third, based on the result, the government should enhance the start-up support system perception even more by seeking ways of efficient publicity to enable more preliminary start-up businesses to participate in diverse start-up support policies. Lastly, it discusses the limitations of this study as well as proposal for ensuing study plans.

The use of planning support systems in urban planning and management provides objective information that is beneficial in the decision-making stage. The existing planning support system, however, lacks in the consideration of ecological properties. In this study, a planning support system development that is capable of reflecting ecological elements was set as the ultimate goal. This system can support planning processes ranging from ecological potential anaylsis to alternatives designing and stimulation. Additionally, factors such as soil, water, climate, biotope, ecological network and recreation can be handled according to their natural potentials. The establishment and visualization of land use planning that addresses ecological characteristics based on the analyzed results are possible. Therefore, this system could operate as a framework to assist planners and decision makers through a computer-based system to provide useful ecological information and to allow effective decision-making by analyzing, displaying and visualizing ecological spatial data.

Field study improves students' capacity for studying and thinking about their surrounding environments. It also develops further interest academic study by allowing them to learn curriculum related materials from actual experience. Moreover, students acquire the capacity for independent and self regulated learning in the course of making efforts to solve problems they face in the environment. Our efforts arc directed at designing and developing a RFID based support system-based on the constructionist's learning theory to help students perform field study more efficiently. The field study support system can be implemented not only in museums but also in botanical gardens, zoos, art galleries, and science centers. Based on the results of the verification at the sample museum we will expand the target locations to implement the field trip support system. We expect that our field study support system will be a catalyst for improving learning in the fields.

The purpose of this study is to design and develop an e-mentoring system for full inclusion. Through the literature review of related studies, the e-mentoring performance model was drawn. Based on this model, an e-mentoring system was designed and developed. Especially the horizontal mentoring was mainly considered during the procedure. To evaluate the usability of the system, 2 system managers, 5 mentors, and 5 mentees were chosen and they were interviewed by researchers. Researchers used an interview instrument(10 items) consisting of mentoring support(cognitive support, affective support, adaptability) and technical support(convenience, accuracy, look & feel) categories. On the whole affirmative responses were given in both mentoring support and technical support areas. It can be concluded that the e-mentoring system is very effective in supporting full inclusion. In future it is recommended that several empirical studies of utilizing the e-mentoring should be performed.

The study conducts a comparative study of the supporting systems and methods of social enterprises in Korea, Japan, and Hong Kong to propose a policy on sustainable growth of social enterprises and their long-term activation. By investigating previous studies, this researcher drew the frame of a comparative analysis and conducted the comparative analysis. First, regarding the supporting system for social enterprises, it was found that Korea had better institutional foundation and system, whereas Japan had better activation, cooperation and network of intermediary support organizations. In Korea there is the law related to social enterprises, and the government takes control of all of the organization in charge of the policy, intermediary support organizations, cooperation and network, and authentication system. However, Hong Kong has yet to establish a basic institutional system to grow and activate social enterprises, and foreign intermediary supporting organizations increase the network and cooperation level to support social enterprises. Thirdly, for supporting methods for social enterprises, there were direct financial support, indirect business support and other kinds of support in Korea, whereas indirect support was activated in Japan. Although The Hong Kong government barely supports social enterprises, it comes up with a plan to support the firms serving as social enterprises under its the 12th 5-year development plan. For sustainable growth of Korean social enterprises, this study suggested the change of the government policy to the direction of creating social enterprise ecosystem through cooperation and network activation, indirect support in the middle of process, and activation of intermediary support organizations.
