Authors: N Nikitha , Mateti Keerthan Raj
Published: August 2023

Abstract: Road accidents frequently result from fatigued or sleepy drivers. More people die and are killed worldwide each year. Driver fatigue is a major factor in many accidents. It is currently one of the major causes of accidents. Numerous facial expressions, such as frequent yawning, frequent eye blinking, and head positioning, might indicate how tired someone is. Computer vision is the most suitable and practical technology to solve this issue since it uses these sensory properties. The suggested methodology employs Dlib, CNN, and OpenCV. Dlib estimates the positions of 68 coordinates (x,y) that help in mapping the facial points on a person’s face. The 2904 pictures that make up the collections classified are Open Eyes, Closed Eyes, Yawning,or No-Yawning. A convolutional neural network (CNN) will be used to determine the mouth and eye states from the Regionof Interest (ROI) photographs. The amount of mouth opening (FOM) and the percentage of eyelid closure (PERCLOS) overthe pupil are the measures used to measure weariness over time. The recommended system determines whether the driver is sleepyand sounds a warning when it detects their eyes and yawns fora certain amount of time. The accuracy of the model has been discussed.

Objectives The purpose of this study was to examine the experience and meaning of mentoring participation in cyber universities and to confirm the importance of mentoring. Methods For this, this study openly recruited people with experiences of participating in mentoring in A cyber university, and then selected total ten mentors and mentees as research participants. After conducting interviews through semi-structured questionnaire and open-ended questions, the collected data was analyzed in the consensual qualitative research(CQR) method developed by Hill et al.,(1997). In the rating team, three researchers repeated the process of consenting by exchanging opinions, and through this process, they made efforts to secure objectivity in data analysis and interpretation. Results The mentoring of cyber university was classified into four areas such as ‘motive for participation’, ‘participatory experience’, ‘result of participation’, and ‘development direction’. First, the necessity to get help for study or experience of getting help in the past was the motive for participation. Second, even though mentoring was helpful to themselves, they also felt like mentoring was not helpful, so they had both positive and negative experiences. Third, they were adapting themselves to school life by not only expanding their learning and school activities, but also maintaining the method of studying and interpersonal relationships with peers. Lastly, this study presented the development direction of mentoring by revealing the effectiveness and necessity of mentoring. Conclusions This study verified that mentoring played effective roles in adapting to cyber university and continuing study.

Published: August 2023

Objectives The purpose of this study is to explore the utilization of Aesop's Fables in moral education, with a focus on the revised 2022 elementary school moral education curriculum. Methods To this end, I would like to present the individual fables of Aesop’s Fables by linking the content system of the 2022 revised elementary school moral education curriculum. In addition, it was intended to provide information and reasons for fables to be careful when using Aesop’s Fables in elementary school moral subject education. Furthermore, in order to pursue the formality of moral development in moral education, I tried to illustrate major learning questions and simple utilization measures through Aesop’s Fables. Results Aesop’s Fables were related to 202 in the “Relationship with oneself” section, 85 in the “Relationship with Others,” 46 in the “Relation with Society and Community” section, and 25 in the “Relation with Nature” section, which is the content system for the 2022 revised elementary school moral education curriculum. In detail, Aesop’s Fables could be linked to 19 content systems of questions and achievement standards. In addition, from Aesop's fables, I was able to extract 192 fables to be careful about in terms of “sincerity”, “consideration”, “justice”, “responsibility”, which are the core values of the moral education curriculum, and “sexual ethics”. And, moral questions for each fable were proposed for an approach to the formality of moral development of moral education. Finally, I was able to select ‘Wolf and Dog’ fable and present some examples of using them as a formal approach to moral development. Conclusions Aesop's Fables, which has been used as a moral story resource for a long time, can be effectively utilized as a story material for the revised 2022 elementary school moral education curriculum's content system and achievement standards and approaches to moral development forms.

Pengoperasian transmisi listrik tak luput dari berbagai gangguan yang dapat merusak keandalan sistem dari penyaluran listrik. Anomali hotspot merupakan anomali yang sering terjadi serta memiliki dampak yang besar jika sudah menjadi gangguan jika tidak ditangani secara cepat. Anomali hotspot merupakan kelainan temperatur yang terjadi pada peralatan yang dialiri arus listrik umumnya terjadi pada titik sambungan. Hotspot dapat menyebabkan kerugian karena energi listrik diubah menjadi energi panas pada titik terjadinya hospot. Hotspot juga dapat menyebabkan rusaknya bagian peralatan transmisi. Anomali hotspot dapat diketahui dengan cara inspeksi titik sambungan menggunakan alat thermovisi. Seperti yang terjadi pada klem jumper konduktor fasa S pada SUTT 150kV jalur penghantar Ujung Berung – New Rancakasumba T.13 penghantar I. Perbaikan hotspot dapat dilakukan dengan 2 pilihan metode kerja yakni dengan pemadaman listrik atau tanpa pemadaman listrik (PDKB). Dari perkembangan kebutuhan energi listrik maka bertambah besar pula keinginan masyarakat terhadap semakin baiknya pelayanan dan kontinuitas penyaluran energi listrik. Dari data perhitungan perbandingan suhu antara objek sambungan dengan konduktor terdapat 2 objek pada fasa S yakni terminal jumper string luar dan dalam yang mengalami anomali hotspot nilai string dalam sebesar 79,2 oC dan string luar 90,0 oC maka di rekomendasikan perbaikan <3 hari. Dari hasil perbaikan hotspot ini menggunakan metode PDKB ∆T turun menjadi 33 oC sesuai SKDIR 520 direkomendasikan penegcekan rutin.

Smart Garden merupakan sebuah rancangan sistem kebun pintar. Teknologi Smart Garden berfungsi untuk menyiram tanaman, mengukur kelembapan kadar air dan suhu dalam tanah. Tanaman cabai membutuhkan perhatian khusus untuk membudidayakannya sampai berbuah. Dari dasar itulah penulis mendapatkan sebuat konsep Rancang Bangun Smart Garden Sistem Menggunakan Sensor Soil Moisture yang dapat mengukur kelembapan tanah dan suhu pada tanah Dengan Kontrol Berbasis IoT yang dapat di kontrol jarak jauh menggunakan aplikasi telegram. Perancangan alat Smart Garden menggunakan esp 8266 12E, Sensor DHT 11 dan Sensor Soil Moisture. Hasil pengujian sensor soil moister sebanyak 5 kali percobaan dengan hari yang berbeda beda. Yaitu dengan cara perbandingan sensor soil moisture dengan soil meter yang mendapatkan hasil nilai kelembapan yang sesuai dari range nilai soil meter terhadap Soil Moisture. Pengujian sensor DHT11 dengan cara membandingkan hasil sensor dan thermometer smartphone serta membandingkan dengan soil meter, yang mendapatkan hasil percobaan berselisih 1.6°C dengan smartphone dimana hasil sensor DHT 11 29.6°C dan hasil pada smatphone 28°C, dan untuk hasil perbandingan sensor DHT11 dengan Soil Meter mendapatkan hasil yang sama yaitu 31°C. Pengujian waktu sensor DHT11 hasil rata rata delay sensor DHT11 sebesar 3.38 detik. Dan Pengujian delay aplikasi telegram dengan cara menghitung waktu delay command “Status” dan notifikasi “Status Soil Kering, penyiraman otomatis Aktif” maka mendapatkan hasil rata rata delay untuk command “Status” yaitu 10.60 detik dan untuk notifikasi “Status Soil Kering, penyiraman otomatis Aktif” yaitu 7.92. maka dapat disimpulkan bahwa delay notifikasi “Status Soil Kering, penyiraman otomatis Aktif” lebih cepat dari pada command “Status”.
Do institutional investors promote sustainability in family business? Evidence from Italian listed firms
Authors: Arduino Francesca Romana
Published: August 2023

The aim of this study is to investigate the role of institutional investors in promoting sustainability in family firms, measured in terms of corporate sustainability performance (CSP) and sustainability disclosure. Due to societal pressure, firms have started to engage more in pursuing sustainable practices and embracing sustainability tenets, and from a governance perspective, they have begun to make changes and adapt their governance structures. The demand for sustainable corporate governance and CSR-oriented initiatives is particularly relevant for family firms, considered to be more long-term oriented. This study contributes to the ongoing debate about the antecedents of corporate sustainability outcomes, shedding some light on the role of institutional investors’ ownership by analyzing as a sample all the Italian non-financial family firms listed on the Italian Milan Stock Exchange between 2011 and 2021. Understanding how the presence of institutional investors contributes to fostering sustainability in family businesses can be beneficial to both the firms and the society.

Antes de que la educación fuese institucionalizada en su práctica, el saber se gestaba y desarrollaba en el seno mismo del intercambio social. Por tal motivo, podría afirmarse que la extensión universitaria es ese intento de revitalizar los saberes y conocimientos devolviéndoles su significancia en dicho escenario. Es decir, una búsqueda de mancomunar el «conocimiento científico, tecnológico, artístico y cultural, la vinculación con la realidad social, cultural, económica y productiva de la región y del país». La Universidad Tecnológica de Pereira no ha sido ajena a las dinámicas que se han posibilitado en los últimos años y, en consonancia con estas, ha propendido por potenciar la interrelación —tan necesaria en los tiempos actuales— entre la academia y su entorno (llámese instituciones educativas, sociedad civil, estado o empresa). En este contexto, la Vicerrectoría de Investigaciones, Innovación y Extensión llevó a cabo la «Convocatoria interna para la financiación de proyectos de extensión social, cultural y artístico» en el año 2020. Con esta convocatoria, se tenía como objetivo incentivar la ejecución de proyectos que, mediante los componentes descritos, generaran soluciones a diversas problemáticas de las comunidades del Eje Cafetero (Caldas, Risaralda, Quindío) durante el año 2021.
