This study was developed to investigate parents' perceptions and attitudes towards distance learning in response to many schools' closures due to the COVID-19. This research employed a qualitative approach. The research subjects consisted of parents of elementary school students in the City of Gunungsitoli, Indonesia determined by purposive sampling technique, totaling twenty-four people. The data were collected using semi-structured interview techniques and analyzed using thematic analysis techniques. This study shows that distance learning or learning from home in a research context takes the form of online and offline learning. The learning approach implemented during the COVID-19 emergency must be lived and supported without other options for parents. Although parents do not have negative perceptions, distance learning has increased the economic, psychological, and social burden on parents or families. The lack of parental involvement and support in children's learning process at home is generally due to the lack of time and parents' inability to become teachers for their children. Actions to accompany and support children's learning process at home are carried out to provide internet packages, help children master the material, and participate in completing assignments or tests given by the teacher. The surprising finding from this study is the decline in children's learning motivation and cognitive abilities. Parents hope that distance learning is not extended.

The role of teacher as a guide is very significant in teaching, especially to equip students to know God through Christian education. Teachers guide the students to understand knowledge, attitudes, skills, and spirituality based on Biblical principles. But in reality, teachers do not teach the Bible principles in learning, teachers do not guide the students, and have lack of knowledge of the Bible. Teachers should have understood the significance of guiding students based on the Bible. Hence, the purpose of writing this article is to present the significant role of teachers as a guide through the theological study based on Ephesians 4:11-16 for the context of Christian education with literature study as the research method. Teachers must guide students based on the truth of God's Word, through imitating Jesus as the Great Shepherd. Christian teachers’ role as guide do not only stop at knowledge in academic learning, but to be an impact for students to be a part of service to God and to build others up as members of the body of Christ. Christian teachers must guide students to achieve, namely: the unity of the faith in Christ as God and Savior in true knowledge, thorough maturity, and growth in accordance with the fullness of Christ and to ensure to be not tossed around by the waves of false teaching that ignore The Lord. This article concludes that the teacher's role as guide is one form for equipping students to grow more mature in Christ. The author suggests that Christian teachers understand that teachers are God's calling to reveal God's truth to students so that their lives base on Bible teaching, and Christian teachers must understand the students' needs to know God and grow spiritually to become more like Christ. BAHASA INDONESIA ABSTRACT: Peran guru sebagai pembimbing sangat penting dalam pengajaran, terutama untuk memperlengkapi murid-murid mengenal Tuhan melalui pendidikan Kristen. Guru membimbing murid untuk memahami pengetahuan, sikap, keterampilan, dan kerohanian berdasarkan prinsip-prinsip Alkitab. Namun pada kenyataannya, guru tidak mengajarkan prinsip-prinsip Alkitab dalam pembelajaran, guru tidak membimbing siswa, dan memiliki pengetahuan yang kurang tentang Alkitab. Seharusnya para guru memahami pentingnya membimbing murid berdasarkan Alkitab. Oleh karena itu, tujuan dari penulisan artikel ini adalah untuk memaparkan peran penting guru sebagai pembimbing melalui kajian teologis berdasarkan Efesus 4:11-16 dalam konteks pendidikan Kristen dengan metode studi literatur. Guru harus membimbing siswa berdasarkan kebenaran Firman Tuhan, dengan meneladani Yesus sebagai Gembala Agung. Peran guru Kristen sebagai pembimbing tidak hanya berhenti pada pengetahuan dalam pembelajaran akademis, tetapi menjadi dampak bagi siswa untuk menjadi bagian dari pelayanan kepada Tuhan dan membangun orang lain sebagai anggota tubuh Kristus. Guru Kristen harus membimbing murid-muridnya untuk mencapai, yaitu: kesatuan iman kepada Kristus sebagai Tuhan dan Juruselamat dalam pengetahuan yang benar, kedewasaan yang menyeluruh, dan pertumbuhan yang sesuai dengan kepenuhan Kristus serta memastikan agar tidak terombang-ambing oleh gelombang pengajaran palsu yang mengabaikan Tuhan. Artikel ini menyimpulkan bahwa peran guru sebagai pembimbing adalah salah satu bentuk untuk memperlengkapi murid-muridnya agar bertumbuh semakin dewasa di dalam Kristus. Penulis menyarankan agar para guru Kristen memahami bahwa guru adalah panggilan Tuhan untuk menyatakan kebenaran Tuhan kepada murid-muridnya agar hidup mereka didasarkan pada pengajaran Alkitab, dan guru Kristen harus memahami kebutuhan murid-muridnya untuk mengenal Tuhan dan bertumbuh secara rohani agar semakin serupa dengan Kristus.

Humans can only understand salvation through God's revelation in the Bible. The Bible teaches that the matter of salvation is both God's sovereignty and man's inseparable responsibility, which is understood as a paradoxical concept. But in reality, 6 out of 11 Christian students do not understand the paradoxical truth about salvation taught by the Bible according to a randomly distributed survey. Christian students who have accepted theological doctrines should understand the paradoxical truth about salvation. An important aim of writing this essay is to show the understanding of Reformed theology (represented by John Calvin, Louis Berkhof, Anthony Hoekema, and J.I. Packer) regarding salvation as God's sovereignty and human responsibility using literary sources. Reformed theologians (Calvin, Berkhof, Hoekema, and Packer) accepted the paradoxical concept and believed that humans contribute to the regeneration of identity through God's grace. God's grace is the main reason humans can obey this. Therefore, understanding the concept of paradoxical truth must be accompanied by love and humility before God. BAHASA INDONESIA ABSTRACT: Manusia hanya dapat memahami keselamatan melalui wahyu Allah melalui Alkitab. Alkitab mengajarkan bahwa mengusahakan keselamatan adalah kedaulatan Tuhan dan tanggung jawab manusia yang tidak terpisahkan, yang dipahami sebagai konsep paradoks. Namun pada kenyataannya, 6 dari 11 mahasiswa Kristen tidak memahami kebenaran paradoksal tentang keselamatan yang diajarkan oleh Alkitab, berdasarkan survei yang disebarkan secara acak. Mahasiswa Kristen yang telah menerima doktrin teologi seharusnya memahami kebenaran paradoksal tentang mengerjakan keselamatan. Tujuan penting dari penulisan esai ini adalah untuk menunjukkan pemahaman teologi Reformed (yang diwakili oleh John Calvin, Louis Berkhof, Anthony Hoekema, dan Packer) mengenai keselamatan sebagai kedaulatan Allah dan tanggung jawab manusia atas keselamatan dengan menggunakan sumber-sumber literatur. Konsep paradoksal dalam mengerjakan keselamatan sebagai kedaulatan Allah dan tanggung jawab manusia. Kebenaran yang diajarkan oleh Alkitab, para teolog Reformed (Calvin, Berkhof, Hoekema, dan Packer) menerima konsep paradoksal dan percaya bahwa manusia berkontribusi dalam regenerasi identitas melalui kasih karunia Allah. Kasih karunia Allah sebagai penyebab utama manusia dapat taat mengerjakan keselamatan. Oleh karena itu, memahami konsep kebenaran paradoksal harus disertai dengan kasih dan kerendahan hati di hadapan Tuhan.

The aim of this paper is to provide some indications for carrying out the risk assessment for the activation of a production line of a radiopharmaceutical containing a positrons emitting radionuclide. The risk analysis was performed by following the ICH Q10 guideline and ISO 9001:2015 standards and by using the risk-based thinking approach applied to the entire production cycle. The overall analysis has shown that hard and soft skills of the expert group are key factors of success both in technical and radiopharmaceuticals-related preparations as well as in risk management methodologies.

Students’ learning activeness is crucial in the ongoing learning process. In fact, there are still students who do not have active in learning. Based on the observation, it was found that there were still students who did not have active in learning. Students never expressed opinions and questions, students were not enthusiastic, students played or talked with friends during the learning process, students hesitated to express opinions, students often got permission to leave class, and students did not contribute to group discussions. The solution to these problems is to apply the game method in learning. The aim is to explain that the application of the game method can increase the students’ activeness in learning during the learning process in the classroom. The method used is a descriptive qualitative method. The result is that the application of the game method can increase students’ learning activeness. It is marked by a change in the response showed by students in which students become enthusiastic while participating in learning, students actively ask and answer questions, and students are actively involved in discussions and some of them are in accordance with indicators of student’s learning activeness. Nevertheless, to obtain significant results, a teacher can apply this method repeatedly. As a Christian teacher, of course, the teacher must be able to use their abilities and intellect to see the problems that students are experiencing in class, then the teacher seeks the right solution based on Bible truth. The suggestion that can be given to teachers is to evaluate the problems of students’ learning activeness in order to be able to determine other methods that are more effective for the improvement of students’ learning activeness.

Risk assessment and management during the entire production process of a radiopharmaceutical are pivotal factors in ensuring drug safety and quality. A methodology of quality risk assessment has been performed by integrating the advice reported in Eudralex, ICHQ, and ISO 9001, and its validity has been evaluated by applying it to real data collected in 21 months of activities of 18F-FDG production at Officina Farmaceutica, CNR-Pisa (Italy) to confirm whether the critical aspects that previously have been identified in the quality risk assessment were effective. The analysis of the results of the real data matched the hypotheses obtained from the model, and in particular, the most critical aspects were those related to human resources and staff organization with regard to management risk. Regarding the production process, the model of operational risk had predicted, as later confirmed by real data, that the most critical phase could be the synthesis and dispensing of the radiopharmaceuticals. So, the proposed method could be used by other similar radiopharmaceutical production sites to identify the critical phases of the production process and to act to improve performance and prevent failure in the entire cycle of radiopharmaceutical products.

Brazil’s presidential elections held last October were the closest in the country's history. The results reflect the polarized political environment and the scenario of political violence, institutional delegitimization, and social unrest perpetuated by the bolsonaristas, which reached its peak with the assault on the Palácio do Planalto This was the concluding act of a process of construction of dialectical and visual violence, steeped in denialism and delegitimization of the opponent. This led to a highly conflictual and aggressive electoral space, that institutions like the Tribunal Superior Eleitoral and Transparência Eleitoral Brasil tried to counter. This essay investigates the pre-and post-electoral violence and the role of the institutions designated to mitigate it.
