Objectives This study aimed to obtain educational implications by collecting and analyzing data on the perceptions and demands of students in Daegu in July 2022, the educational recovery stage. Methods To this end, from July 7 to 21, 2022, through an online survey, elementary, middle and high school students in the Daegu area were surveyed for their perceptions and demands for school life. The contents of the survey were the degree and difficulty of daily education recovery, students' school life and changes, corona stress, information utilization level, positive and negative changes after COVID-19, school life adaptation and positive psychological capital. The collected data were analyzed and described using Spss 26. Results Students recognized that field experiential learning and physical activities were effective as methods of psychological emotional and social recovery. Recognition of daily school life was average, but trust in others and the country was below average. In addition, the contents they wanted to receive help from teachers were career path, help for higher education, and encouragement for learning. The need for community education and health education was greatly recognized. The higher the positive psychological capital, the higher the school life adaptability and overall satisfaction with school life. Efforts are needed to find out and utilize the positive characteristics of students in the educational recovery stage. Conclusions We looked at the meaning and direction of the educational recovery introduced in public education, and rethought many issues raised while experiencing the corona. Restoration of education does not mean a return to the past, but includes the meaning of reconstruction. Therefore, ‘forgetting’ was changed to ‘remember’ will, and ‘passive’ was changed to ‘active’ action, suggesting what the educational world should prepare for.

Published: August 2023

Objectives The purpose of this study is to identify the content changes and trends of the beauty pedagogy questions by analyzing the secondary school beauty teacher recruitment test items. Methods According to the Korea Institute for Curriculum and Evaluation(KICE), the secondary school beauty teacher recruitment tests from 2014 to 2023 had 30.5 questions in total for beauty pedagogy, including 7 questions in 2014, 4 in 2015, 4 in 2016, 5 in 2018, 5 in 2020, and 5.5 in 2023. This study analyzed them by year, evaluation areas and contents after verified by expert group, adopting an item analysis framework (beauty department curriculum, teaching⋅learning model, evaluation). Results First, the test has had a different rate of questions for beauty pedagogy, leaving a couple of years below the standard. Second, evaluation areas have been heavily weighted towards teaching⋅learning model, excluding the curriculum and evaluation occasionally. Third, most of the evaluation content consists of teaching⋅learning method application and evaluation method, which doesn't cover various content elements. Conclusions First, additional research should be conducted to develop the qualification standards, elaborate the evaluation areas, and evaluate the teaching performance for the indication subject,｢beauty｣, which has not been supplemented since 2008. Second, referring to the latest academic trends, we should set questions from diverse areas such as curriculum, teaching⋅learning model, and evaluation, and create a more intensive level of questions connecting pedagogy with content knowledge, relieving the overweight of beauty teaching⋅learning model part. Third, we demand follow-up research on content knowledge of beauty education, including pedagogy to help exam writers and prospective teachers to use them as a reference.
Exploring the direction of developing achievement standards for competency-based curriculum through analysis of previous studies related to content standards and performance standards
Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Han Hyechong
Published: August 2023

Objectives The purpose of this paper is to solve the confusion about the statement of achievement standards in Korea in relation to the meaning of content standards and performance standards, and to explore the direction of development of achievement standards for competency-based curriculum. Methods To this end, the content of 12 previous papers dealing with the meaning of content standards and performance standards were analyzed. Results As a result of the analysis of previous studies, the meaning of content standards is divided into two categories; ‘standards for what students need to know’ and ‘standards for what students need to know and can do’. Performance standards are ‘standards of what can be done’ if content standards are defined in the former meaning, and if defined in the latter meaning, it turns out that the performance standard can be understood in the following three meanings; a statement focusing on the application of knowledge, a statement focusing on the application of knowledge with a clue for achievement, criteria for evaluating the level of achievement or mastery of how well the knowledge and skills included in the content standard are learned as a result. Conclusions As a result of searching for the cause and solution of the confusion about the meaning of content standards and performance standards, content standards are ‘standards of what to know and can do’, and performance standards are criteria for evaluating the level of achievement or mastery of how well the knowledge and skills included in the content standard are learned as a result. As a direction for development of achievement standards for competency-based curriculum, a method of presenting achievement standards by each category of knowledge, skills, values and attitudes, rather than being stated as a combination of content elements of knowledge, skills, values and attitudes, was proposed.

Published: August 2023

Objectives The purpose of this study is to develop an inquiry model that can be applied to various fields based on ‘education through science’. Methods First, 137 literature related to ‘exploration’ were analyzed and an integrated initial inquiry model that could be universally applied was developed. The applicability of the model to 20 field teachers in various fields was reviewed and internal validation was conducted. Afterwards, an inquiry class was formed based on the model and applied to three teams of middle and high school students to conduct external validation of the inquiry model. Results The developed TSU model goes through three stages: problem recognition (Thinking), problem solving (Solving), and knowledge utilization (Using). Each stage includes two of the six elements: theme setting and research design, research execution and results arrangement, knowledge application and communication. The elements of the inquriy are selectable, the starting stages can be set differently, and the entire quest process is characterized by a spiral cycle. These characteristics were considered to be applicable to various fields as a differentiated part from the existing inquiry model. It was confirmed that the aspects appearing in the actually applied inquiry class are the same as the context of the existing inquiry model and do not deviate from the essence of inquiry. Conclusions The TSU model is an inquiry model that can be applied to various fields and school levels, and has significance in integrating the research models presented so far into one. In order for the inquiry model to be well applied to the field, a field should be prepared to activate the community of teachers who share inquiry lessons and to collect and unfold records from the field. In addition, in order to increase the validity of the inquiry model, it is proposed as a follow-up study to transform and expand the inquiry model through various school levels and various fields, or apply it to the online environment and other cultures.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Kim Chae-won , Kim Myeung-chan
Published: August 2023

Objectives My story aims to present the process of my experience of self-criticism and acceptance as a counselor and the counseling meaning of such a process. Methods I applied the method of autoethnography to critically analyze the concept and customs of the socio-cultural community inherent in personal narratives by extracting the socio-cultural context embedded in autobiographical stories. Results As I experienced abuse from significant others as a child, I internalized self-criticism, which led me to live at a distance from myself and others. To escape from these problems, I majored in counseling. Through the experience of educational analysis and supervision, and the process of collaboratively writing my autoethnography, I could experienced a therapeutic relationship. As a result, I was able to gradually break away from self-criticism and, little by little, I was able to accept myself as I am. Conclusions My story suggests that the narrative of self-criticism internalized through relationships can be corrected through therapeutic relationships. And in that respect, this story will be a counseling case on self-criticism.

Published: August 2023

Objectives In this study, we derive the meaning of elementary school teachers' experience of dealing with school violence cases. By understanding how the principal's self-solving system is currently being implemented in school, this study was conducted to provide prevention and countermeasures against school violence, improvement in the process of dealing with school violence, and educational insights. Methods To this end, a researcher in charge of school violence affairs at A elementary school received 11 cases and investigated the relationship between students, parents, administrators, and people involved in the school principal's self-solving settlement while conducting an investigation. In addition, in order to express the in-depth experience of the case handling process from the perspective of the teacher in charge of school violence who handles the case in connection with the school principal's self-solving settlement and the school violence countermeasure committee, the research method of self-cultural description was applied. Results Through Auto-ethnography research, It was derived into five categories as ‘Teachers avoiding school violence, and the person in charge of school violence is left alone’, ‘Non-existent human rights of school violence case handling Teacher’, ‘Schools unable to view school violence educationally’, ‘It is neither a solution nor an education, but the school principal's own solution’, ‘Laws and policies that want teachers to be supermen’. Conclusions Based on the research results, the following conclusions were reached. First, it is necessary to change the school violence work process into a multi-dimensional joint work process. Second, it is required to guarantee teachers' teaching rights and basic human rights while dealing with school violence cases. Third, it is necessary to devise an educational plan for handling school violence issues and consider educational effects. Fourth, institutional reorganization is required so that the school principal's self-solving system can be a true solution. Lastly, accountability in the process of dealing with school violence cases carried out by schools and compulsory participation in case investigations should be given. The research proposal suggested the need for additional research in various forms on the principal's self-solving solution in connection with the first study on the principal's self-solving solution.

Patients’ demographics such as age and gender, the reason for admission, the time of admission, the clinics the patients were admitted to, the prognosis of the patients in the emergency department (ED) or in the clinics they were hospitalized were recorded. Patient information was obtained from ED patient records, hospital information management system and forensic reports, retrospectively.
Results: The mean age of the 46,732 patients was 31.77±16.68 years. Mortality occurred in 246 (0.5%) patients. The admissions were higher in July and August compared to other months. The most frequent presentations were in the evening hours. The cases between the ages of 20-29 were much higher than other age groups. The most common type of forensic cases was traffic accidents in 23,177 (49.6%) patients followed by assault in 8,521 (18.2%) patients, occupational accidents in 5,680 (12.2%), and 5,576 (11.9%) drug intoxication.
Conclusion: Traffic accidents take the first place in order of frequency in forensic incidents, which are observed 2.08 times more in men than in women. There is a need for further similar studies in order to develop standards, protocols and policies in prevention and management of forensic cases.

Air receiver tank in electrical generator used as pressured air vessel is mainly consisted of shell cylinder and head part. This work has searched for the more suitable material to be used for the shell and head of the proposed air receiver tank because the older material (SPV 355) has some limitations. This study has been conducted based on several parameters in standard references. The calculations have applied relevant technical formulas such as corrosion factor, thickness design, and Maximum Allowable Working Pressure (MAWP). There are three types of selected materials available that are expected to yield similar previous condition parameters addressing to operational pressure 10 bar and temperature 40oC, i.e., SA-36 (Type I), SA-516 Gr 70 (Type II), and SS-304 (Type III). The economic factor is also taken into consideration. Considering the economic cost and mechanical characteristics, finally the material of Type II is selected to be the most appropriate material to replace SPV 355 material for the proposed air receiver tank. In the upcoming, this study is useful for the knowledge of material design.

Arc Flash adalah pelepasan energi yang disebabkan oleh arus gangguan atau arching fault ataupun bolted fault yang dapat dipicu oleh kelembaban, kegagalan isolasi, human error, serta kegagalan mekanik. PT. Krakatau Daya Listrik (PT KDL) bergerak di bidang pembangkitan dan pendistribusian listrik di Kawasan Industri Krakatau. Salah satu gangguan yang sering terjadi pada jaringan distribusi di PT KDL adalah gangguan yang diakibatkan oleh busur api (arc flash). Penelitian ini bertujuan menganalisis pengaruh Setting OCR terhadap arc flash saat terjadi short circuit di Panel AK19 Substation Diesel PT KDL pada tegangan 20kV. Analisis data penelitian ini mengacu pada standard IEEE 1584 - 2002 dan Metode Ralph Lee kemudian disimulasikan dengan software ETAP Power Station menggunakan data aktual lapangan. Hasil analisis menunjukkan Fault Clearing Time (FCT) memberikan perubahan yang cukup signifikan terhadap besarnya arc flash yang ditimbulkan ketika terjadi gangguan hubung singkat 3 fasa. Insiden energi (E) arc flash pada penelitian ini yaitu 58,35 Cal/cm2 dengan FCT sebesar 0,3 s pada panel 20 kV, dan insiden energi yang dihasilkan analisa paling kecil yaitu 5,8 Cal/cm2 dengan FCT sebesar 0,03 s. Hal ini membuktikan bahwa semakin cepat FCT maka besar insiden energi arc flash yang terjadi semakin kecil, sebaliknya semakin besar atau semakin lama FCT maka semakin besar insiden arc flash yang terjadi. Gangguan hubung singkat  ini sangat dipengaruhi oleh perhitungan besar energi arc flash dan jarak batas perlindungan. Berdasarkan tabel Hazard Risk Category (HRC) diketahui bahwa semakin cepat FCT maka semakin kecil kategori Personal Protective Equipment (PPE) sesuai standard NFPA 70E 2018.

Dentro de las formas de integración de las organizaciones deportivas en el mundo, la más frecuente y utilizada es la denominada “de Afiliación.” Cuando un deportista se inscribe en un club deportivo aficionado, está ejerciendo una de las libertades consagradas en la Declaración Universal de los Derechos Humanos, además de integrar la base de una pirámide que, desde el ámbito local, va estructurándose hasta llegar a las federaciones internacionales. El asociacionismo deportivo constituye un movimiento social encaminado a conformar organizaciones especializadas en la promoción de una o varias actividades deportivas, a regular su práctica, a ejercer el monopolio sobre estas, a organizar sus competencias (torneos) y en algunos niveles a explotarlas económicamente. El deporte asociado ha adquirido una importancia social, política y económica que ha servido para que las ciencias jurídicas y administrativas dirijan su interés hacia él y que a través de investigaciones se puedan aportar propuestas a los problemas y necesidades que surgen de esta nueva realidad. Por tal motivo, se propuso indagar el estado del asociacionismo de los clubes deportivos aficionados en el departamento de Risaralda ya que, durante los últimos años se ha observado una notoria desarticulación del sistema de asociación deportiva. Esta desarticulación ha influido negativamente en el correcto desarrollo del sistema de integración, debido en gran porcentaje al desconocimiento de sus derechos y beneficios derivados de la pertenencia a esta estructura. A partir de lo anterior, la línea de investigación en gerencia y derecho deportivo GIGEDE del grupo de investigación Cultura de la Salud, realizó una investigación descriptiva encaminada a determinar el estado actual del asociacionismo de los clubes deportivos aficionados en el departamento de Risaralda. Se pudo identificar, sobre los 214 clubes aficionados del Departamento de Risaralda (Colombia) las siguientes características: el tipo, vocación y estructura organizativa; el nivel de asociacionismo con implicación de viabilidad técnica y operativa; las razones y criterios de asociación con sus correspondientes ligas y/o federaciones y su relación con el ente gubernamental del nivel correspondiente (municipio). En consecuencia la recolección de información generó aspectos importes tales como los objetivos de cada club, el tipo y estructura que manejan, los tipos de convenios realizados; los años que llevan con reconocimiento deportivo, entre otros aspectos relevantes que permitieran identificar el fenómeno asociado al desconocimiento de las normas y estructura de un club deportivo ya que esto, a su vez, imposibilita la capacidad de gestión y asociatividad a sus correspondientes ligas, federaciones y Entes gubernamentales correspondientes.
A nonreciprocal, magnetic metasurface
Authors: Takahagi Kazuhiro , Tennant Alan
Published: August 2023

Non-reciprocal metasurfaces have recently attracted significant
attention due to their ability to control electromagnetic waves in
unprecedented ways. In this study, we propose a novel, non-reciprocal
metasurface that utilizes a combination of magnetic materials and
electrical conductors to achieve non-reciprocity to plane wave
illumination at microwave frequencies. Experimental results demonstrate
that the metasurface achieves an isolation characteristic of at least 15
dB at 6.5 GHz.
