We introduce the concepts of intuitionistic fuzzy submodules and intuitionistic fuzzy weak congruences on an R-module (Near-ring module). And we obtain the correspondence between intuitionistic fuzzy weak congruences and intuitionistic fuzzy submodules of an R-module. Also, we define intuitionistic fuzzy quotient R-module of an R-module over an intuitionistic fuzzy submodule and obtain the correspondence between intuitionistic fuzzy weak congruences on an R-module and intuitionistic fuzzy weak congruences on intuitionistic fuzzy quotient R-module over an intuitionistic fuzzy submodule of an R-module.

Purpose: The purpose of this study was to develop a PBL module in maternity nursing based on the clinical cases. A PBL module applied to maternity nursing class to test the effects on improving the learning ability of students. And it would be used for developing further PBL module even more perfectly. Method: We selected the concept of the PBL module which is based on the purpose of the contents of maternity nursing class and national test held by Korean Nursing Association. The module scenario was composed up of the cases of clinical practices and was also checked by clinical practice professionals as well as the nursing professionals in other colleges. We used this PBL module for the 20 second grade student nurses in K college for 6 weeks. Besides, we checked self-analyses on the PBL class, assessments done by students on the PBL class itself and on the academic adviser and analyzed the students' subjective statements on the PBL class . Results: The achievements of the experimental students given a PBL class, are better than those of the control group statistically. And the experimental group do their almost all learning planned actively for themselves and show their positive responses on the PBL class being helpful in practicing clinical cases. Conclusion: PBL class could be considered the method to fortify student nurses' abilities on adjusting themselves to clinical real situations through the learning planned by themselves. Afterwards it is necessary to activate PBL class in nurse education. Most of all, it is more important that nurse educators should recognize the values of this PBL class and try to apply it in reality.

This paper proposes a mobile robot platform for education that can experiment with various autonomous driving algorithms such as obstacle avoidance and path planning. The platform consists of a robot module and a remote controller module, both of which are based on the Arduino Nano 33 IoT embedded board. The robot module is designed as a differential drive type using two encoder motors, and the speed of the motor is controlled using PID control. In the case of the remote controller module, a command to control the robot platform is received with a 2-axis joystick input, and an elliptical grid mapping technique is used to convert the joystick input into a linear and angular velocity command of the robot. WiFi and Zigbee are used for communication between the robot module and the remote controller module. The proposed robot platform was tested by measuring and comparing the linear velocity and angular velocity of the actual robot according to the linear velocity and angular velocity commands of the robot generated by the input of the joystick.
