There is a growing interest in and demand for power industry acceleration and energy efficiency due to the increased energy consumption, environmental issues. Electronic power IT convergence industries such as intelligent power system has attract attention as new growth engine industry. A large number of sensors and motors are being installed following unmanned, automated in existing incoming panel management system. Observe the operating conditions and rapid response is essential. Despite the need for immediate action to be taken in the event of various later failed to recognize the emergency power can lead to accidents. In this paper, we propose a new architecture of the implementation of incoming panel monitoring system for power monitoring, fault detection, maintenance and system control using open source hardware platform and Wi-Fi networks.

This study evaluated the completeness of emergency medical service (EMS) activity reports. In all, 67,830 cases of normal transfers were statistically analyzed using IBM SPSS Statistics version 22, and statistical significance was set at p <0.5. The 119EMT_2 certificate was omitted in 50,037 (73.8%) cases, followed by time-related items in 1,227 (1.8%) cases. In the primary assessment of vital signs, systolic blood pressure was omitted and erroneous in 1,218 (1.9%) and 1,129 (1.8%) cases, respectively. In the secondary assessment, the completeness of all vital sign items was approximately 70%. As the severity of the patient's condition increased, the errors in the EMS activity report also increased, at a significant level (p=.00). Paramedics must be aware of the importance of completing the activity report.

This research was done to determine and analyze a qualitative on the essential structure of the experiences of stroke patients with combined treatment of oriental and western medicine. Methods: Participants in this study were targeting 25 stroke patients who live mostly in D city and received the combined treatment of oriental and western medicine, but received oriental medicine treatments based on their own wills. Data were collected and recorded through in-depth interviews. Data analysis was conducted by Colaizzi's phenomenological method. Results: As a result, their acculturation were classified into 21 clusters of theme and 6 categories. Selected 6 categories as follows. 'being severely shocked from sudden attack', 'being depressed with rehabilitation', 'western therapy was more effective in emergency situations', 'having limitations in western therapy', 'selecting oriental therapy for themselves', 'discovering the meaning of rehabilitation in oriental therapy'. Conclusion: Based on these necessary data for systematic oriental rehabilitation development.

In this study, we analyzed the perceptions of elementary school students about science learning and lab safety in the affective, behavioral, and cognitive domains. With respect to science learning, students indicated liking science classes more than average, being good at scientific inquiry more than average, and having more scientific knowledge than average. Compared with before the COVID-19 pandemic, student confidence in retaining scientific knowledge had decreased markedly. Of the eight student types in the students' awareness levels about affective·behavioral·cognitive domain, the HHH type-the most ideal-was also the most distributed. Students' preferred science class methods were experimental (72.7%) and nature inquiry classes (23.2%); science knowledge classes were ranked a distant third (4.1%). Preferred class locations were the science lab (58.1%) and different places from time to time (34.4%); the classroom was ranked last (7.5%). With respect to lab safety, most elementary school students did not have experimental classes, but more than half reported understanding how to use experimental equipment. Most students recognized the need to wear safety equipment in the lab. They were not only well aware of the associated physical protection functions, but also of the affective and psychological effects. Most students also recognized that first aid education is necessary, but only 31.5% reported understanding first aid methods. Based on those results, the implications for science learning and lab safety in school are discussed.

Driving behaviors are reported to be vulnerable to safe driving in unexpected situations or driving in the city due to deterioration of physical and cognitive functions in elderly drivers. The purpose of this study was to investigate the difference in driving behaviors according to age of self-drivers and to identify changes in physical function related to driving caused by normal aging. The subjects of the study included 75 healthy adults (21 persons aged 20-39 years, 40 persons 40-64 years, 14 persons 65 years old) who were self-driving and possessed a driver's license. Data included sex, dominant hand, medication, exercise, age, and driving time obtained by a self-reported questionnaire. In addition, this study measured steering, acceleration and braking using a Driver Test Station. Results of the study showed there was no significant difference in power test according to age group, but the total time of the timer test and the emergency brake test significantly differed according to age. The timer test and emergency brake test were completed fastest in young adults between 20 and 39 years old and completed slowest in elderly people 65 years old or over. Based on our study results, it is suggested that normal aging affects the perceptual-cognitive processes associated with driving behaviors.

The purpose of this study is to evaluate the level of dental trauma management in elementary, middle and high school teachers using questionnaires. 325 elementary school teachers, 101 middle school teachers, and 232 high school teachers, totally 658(males of 362, females of 296)teachers were provided with the questionnaires. Part I in the questionnaires was composed of their gender, age, experience as teachers and whether they received education about dental trauma or not. Part II included questions about appropriate attitudes in case of specific dental trauma. Part III was composed of questions asking knowledges about states of damaged teeth and possible emergency service. The attitude in managing tooth fracture showed significant difference between male and female teachers. The attitude in managing tooth avulsion showed significant difference among elementary, middle and high school teachers. Although it had difference according to questions, insufficient knowledge and awareness about the management of dental trauma were shown in the majority of teachers. It is recommended that educational program for improvement of awareness about immediate management of traumatized teeth is necessary for teachers.
