The arrival of the Web 2.0 age, which is characterized by such key words as participation, sharing and openness, provides a learning environment in which both instructors and students can experience interactivity. In the educational area, we are particularly witnessing a growing interest in the social software like Wiki as one of the communication tools that reflects the characteristics of Web 2.0 and focuses on the interactivity with others. Based on this background, this study aims to examine into the meanings of interactivity inherent in the Wiki-based learning by studying such cases where Wiki is being used as a learning tool. For the purpose of our study, we practiced the Wiki-based learning method on the study subjects of the 17 junior students from U- University and 18 junior students from K- University during their 2009 fall semester teacher training courses. Through a comprehensive analysis of the questionnaires, interviews, Interactivity Measurement Diagram, examinations on the Wiki uses, Daily Self-reflection Records, and any other materials collected throughout the program, we could garner the following results: First, most of the students acknowledged that the use of Wiki was a useful communication means and helped promote their interactivity during their learning activities. Second, the interactivity of the Wiki-based learning was found to be more dynamic in the team-based projects or the community-based Wiki uses than in the instructor-oriented cases. Third, the Wiki-based learning is judged effective in expanding the scope of thinking and improving the learning capabilities through the collaborative knowledge-building process. The educational employment of the social software like Wiki in this web 2.0 age has great potentials for the true establishment of the learner-oriented learning environment, which has long remained at a standstill.

Location-Based Service(LBS) is a service that provides a variety of convenience in life using location information that can be obtained by mobile communication network or satellite signal. In order to provide LBS precisely and efficiently, we have to need technologies such as location determination technology, platform technology and server technology first. In this study, we studied on how we can reduce the error on location determination of objects such people and things. Fingerprint location determination method was applied to this study because it can be used at current wireless communication infrastructure and less influenced by a variety of noisy environment than other location determination methods. We used the time of arrival(ToA) method in fingerprint location determination method. In order to confirm the performance of suggested method, we developed location determination test program with LAbVIEW 2010 and performed the test. According to indoor test results, the suggested method reduced the distance error by 24%, 34% and 19% respectively at indoor environment compared with deterministic kWNN and Rice Gaussian fingerprint methods.

This study was to identify the educational needs for mental health nursing among undergraduate nursing students, prioritizing the areas where require extensive convergence learning via simulation. One hundred and forty students completed the survey where data accrued from between March-May 2020. The educational needs for mental health nursing and nursing care schizophrenia patients were assessed using a self-reporting questionnaire, which included 19 and 15 items, respectively. Additional three essay questions were used to obtain information regarding previous simulation education experience. Higher educational needs in nursing care for schizophrenia were identified and the highest-priority need is communication skills. Factors, including realistic experience with standardized patients, teamwork, and feedback from the lecturers, affect positive experiences in mental health nursing simulation. The findings suggest that educational programs to improve communication skills are necessary for better mental health nursing competency. Well-designed and convergence based simulation programs providing real-like clinical experience would ensure optimal learning outcomes.

This paper proposed face recognition methods about performance improvement of the face recognition using the properties of wavelet transform. Using discrete wavelet transform is Daubechies D4 filter that is similar to mother wavelet transform. For discrete wavelet transform method, In this case, by using LL subband only we can reduce processing time and amount of memory in recognition processing. To improve recognition ratio without further loss of 2 dimensional data changing, We applies 2D LDA. We perform SVM training algorithm to the feature vector obtained by 2D LDA. Experiment is performed using ORL database set and Yale database set by Matlab program. Test result shows that proposed method is superior to existence methods in recognition rate and performance time.

This study examined the perception and readiness of nursing educators regarding interprofessional education (IPE), and discussed the validity and application of IPE in nursing. From December 2016 to January 2017, 239 nursing professors and nurses completed a structured questionnaire consisting of general characteristics, the Interdisciplinary Education Perception Scale, the Readiness for Interprofessional Learning Survey (RIPLS), and an IPE action plan. The collected data were analyzed by descriptive statistics and t-test using the IBM SPSS ver. 23.0 program (IBM Corp., Armonk, NY, USA). The analysis revealed that 91.6% of the participants had not experienced IPE, and only 11.7% knew about IPE. However, approximately 80.0% answered that IPE is necessary. The results of this study showed that the score of the perceived need for cooperation was higher in nurses than it was in professors, while the score on competency and autonomy was higher in professors than it was in nurses. With reference to the scores on the RIPLS, those of professors were high on the sub-scales of teamwork and collaboration, professional identity, and roles and responsibility. The results revealed that participants considered the upper-grade undergraduate years as the ideal time for imparting IPE, and it was deemed suitable to include communication, simulation, and clinical practice in IPE. Doctors, pharmacists, and physiotherapists were thought to require cooperation for IPE the most. Despite the presence of several barriers to IPE, the participants thought that IPE can achieve learning outcomes such as interprofessional communication and cooperation, conflict resolution, and teamwork. It is necessary to cooperate with professionals in the complex clinical environment as professional areas are specialized and subdivided. Therefore, it is necessary to examine the application of IPE in undergraduate education and in on-the-job training.

The CanSat was designed as an educational satellite simulation program that implements the overall system of the satellite such as the command processing unit, the communication unit, and the power unit in a structure of the size of a can. In particular, the training effect is very excellent because the trainee can learn a process similar to the actual satellite development process by designing, manufacturing, testing, and launching. Republic of Korea Air Force Academy has been using the CanSat production kit used by the domestic can satellite contest experience department for education, but since it was produced based on PCB, it was impossible to show creativity and operation was restricted even with small mistakes. In this paper, we analyze the existing CanSat kit and propose a new educational CanSat kit that can be used in creative engineering design and practice subjects that will be reorganized into a regular course from 2021, and a lesson plan. In conclusion, by using the proposed CanSat kit for lectures, it is possible to achieve educational purposes and effects, improve lecture satisfaction, and provide stable instruction.

This study analyzed the effects of the all-in-one automatic fire shutter (hereinafter referred to as "all-in-one shutter") installed along the fire compartment in a five-story high school building on the evacuation time by using the Pathfinder simulation program. When the all-in-one shutter was added as a new variable, the evacuation time was delayed, indicating insufficient evacuation safety. The evacuation time exceeded the appropriate standard when the evacuation exit was designated to the students in the present state of being placed on the 2nd, 3rd, and 4th floors and the all-in-one shutter was activated. When students were placed on the 1st, 2nd and 3rd floors under the same conditions, the evacuation time was also greatly exceeded. However, when the width of the entrance was set to 130cm, the evacuation time was almost the same as when the all-in-one shutter was not installed. In high-rise school buildings, the bottleneck caused by all-in-one shutters is becoming a major factor in evacuation barriers. To ensure the evacuation safety of school buildings, it has been judged that evacuation education and training to predict the evacuation time required through the all-in-one shutter entrance and induce an evacuation procedure suitable for the standard evacuation time should be carried out in parallel. The implications of this study and suggestions for effective fire compartments and follow-up studies were discussed.

This quasi-experimental study was conducted to develop and implement a team facilitation program as well as to evaluate the effects of the program on Problem Based Learning (PBL) and how these influence on team dynamics. Data were collected in a convenient sample of 126 nursing students (intervention group=69; control group=57). Data were analyzed using ${\chi}^2$ test, T-test, and ANCOVA. SPSS23 was used. The intervention group received the PBL team facilitation program, whereas the control group received a human interaction training. The intervention group than the control group demonstrated significantly higher scores in a team dynamic among team members(F=10.35,p<0.01), trust among team members(F=9.86,p<0.01), communication(F=5.69,p<0.05), learning behavior of a team(F=4.57,p<0.05), and individual capability evaluation(F=5.12,p<0.05). Team performance was not significantly different between groups. This study reveals that the team facilitation program is an effective strategy to maximize the effects of PBL. We propose the need for educational strategy to support team function.
