    Plasma-Metal Inert Gas (MIG) hybrid welding was employed to carry out bead on plate welding of an aluminum alloy A5052. The plasma arc was ignited to form a keyhole, and a series of welding systems were developed starting with MIG welding. The convective patterns within the weld pool were meticulously analyzed. In addition, we conducted experimental observations of the flow inside and on the surface of the pool, and we were able to visualize the flow in some areas. The results indicated that the plasma welding side formed a pool that seamlessly integrated the plasma side and the MIG side. At the same time, we observed the formation of a flow pool that integrates both plasma and MIG sides, affecting the formation and behavior of the weld pool. This study aims to provide a nuanced understanding of flow dynamics across the entire pool. This approach is geared towards refining the intricacies of weld pool dynamics for the advancement of welding technologies.

    In this work, the turgo impulse micro hydroelectric system was developed by using water flow in natural pipeline for preparing to energy emergencies of disaster sites. The motorized ball valve was used experimentally to control the water volume for changing to output voltage under different conditions of water head, including 4.5 m, 6.0 m, and 8.0 m. For the results, the influence of water head was investigated concentratedly with the relationship of water flow rate, number of rotations, and output voltage. Note that the number of rotations has a significant effect to the power generator. There have been found that the load power generation will be variation to the load resistance. Mentioned, when the number of rotations is increasing, the output voltage will be risen, which is presented the maximum voltage of 78 V, rotations of 1035 min -1, and water flow of 583.3 x 10-3 m3/s following to the 8.0 m of water head. And, the set water head of 4.5 m and 6.0 m were shown the output voltage by 53 V and 63 V, respectively. Consequently, the optimum result was illustrated by water head of 8.0 m, which showed the highest power of about 5.0 W resulting to use for charging cell phones.

    With Covid-19 pandemic, the Ministry of Education, Culture, Sports, Science and Technology promoted the online education in schools in Japan after the development of Information and Communication Technology (ICT) education upon demand for closure of all the schools. For this reason, the elementary schools across Japan are almost ready to implement ICT education. In this study, we gave an online class on cancer and medical endoscopes at remote location with such ICT environment developed. The comparison of the survey before/after the class revealed the effect on the understanding of innovative medical endoscope technology in the medical and engineering fields, and the effect of the career education for possible stronger interest among children in medical fields after learning about the medical instrument. Here we would like to report the educational effect of the ICT education through online class we verified.
