<p class="abstrak">Mathematics is a subject that is considered a scourge by most students. They think that mathematics is difficult, complicated, and boring. However, if we look at the process of creation, everything in this universe (including mathematics) is God's creation and everything is really good. This truth needs to be revealed to students by the mathematics teacher. Unfortunately, many math teachers make students dislike mathematics. Therefore, this paper aims to describe the role of Christian mathematics teachers to guide students in viewing mathematics according to God's perspective. The research method used is the literature study method. The results of this study indicate that the role of Christian mathematics teachers includes: (1) appreciating and exploring mathematics first; (2) developing the four teacher competencies; and (3) understand the objectives of learning mathematics. Christian mathematics teachers also need to be careful not to fall into the sin of idolatry and pride by asking the Holy Spirit for help to be enabled in each of their ministries.</p><p class="abstrak"><strong>BAHASA INDONESIA ABSTRACT: </strong>Matematika merupakan salah satu mata pelajaran yang dianggap momok oleh siswa. Siswa menganggap bahwa matematika itu sulit, rumit, dan membosankan. Namun jika melihat pada proses penciptaan maka segala yang ada di alam semesta ini (termasuk matematika) merupakan ciptaan Allah dan semuanya sungguh amat baik. Kebenaran ini perlu disingkapkan kepada siswa oleh guru matematika. Namun, banyak guru matematika yang justru membuat siswa tidak menyukai matematika. Oleh sebab itu, tulisan ini bertujuan untuk memaparkan peran guru matematika Kristen di dalam menuntun siswa dalam memandang matematika sesuai dengan cara pandang Allah. Adapun metode penelitian yang digunakan adalah metode studi kepustakaan. Hasil penelitian ini memaparkan bahwa peran guru matematika Kristen meliputi: (1) mengapresiasi dan menjelajahi matematika terlebih dahulu; (2) mengembangkan keempat kompetensi guru; serta (3) memahami tujuan pembelajaran matematika. Guru matematika Kristen juga perlu berhati-hati agar tidak jatuh ke dalam dosa penyembahan berhala dan kesombongan dengan meminta pertolongan kepada Roh Kudus agar dimampukan dalam setiap pelayanannya.</p><p class="abstrak"> </p>

This article is devoted to analysis of the modern problems of book publishing in the context of national information space. Development of the Ukrainian state is impossible without development of national book publishing, which is a part of its information space. In Ukraine, as one of the post-Soviet states, the formation of new information and communication system is based on its own information tradition, mentality and features of spiritual culture of the Ukrainians. It plays an important role in shaping culture, spirituality, comprehensive vision and consciousness of the nation. They were and they are a source of knowledge and the most effective way of its transfer. The transience of processes occurring the era of information society, radical socio-economic reforms, sectoral technological revolution requires the continuous scientific researches and analysis, identifying the trends in publishing industry as one of the most important factors in the state’s democratic progress. The author summarizes the development of book publishing of Ukraine and shows its role and place in the modern information society. The study of the modern book publishing is impossible without digression into the past, without finding out the roots of studying of the analysis object. The specific problems of the book industry are identified. It is concluded that in the modern Ukraine the publishing business has intensified, although the positive changes are taking place very slowly: the appropriate economic conditions for development of the publishing industry have not been created, the equipment are outdated; editorial, publishing and printing equipment of domestic manufacture are nonavailable; introduction of advanced technology are low; purchasing ability of the population is low; the sales network of printed products has been destroyed and so on. The businesses are becoming increasingly uneconomical. We propose some measures to improve this situation, strengthening the role of industry in the national information space. The key to improve the situation may be systematic and persistent efforts of the Ukrainian government to support the industry.The reason is that a comprehensive study requires from the performers not only historical knowledge, but also economic, managerial, psychological, political efforts and so on. The most important thing that the society and the state should need is the component of doctrine of information security in the context of the national security

The application of constructive geometric modeling to pedagogical models of teaching graphic disciplines today is a promising direction for using computer technology in the educational process of educational institutions. The essence of the method of constructive geometric modeling is to represent any operation performed on geometric objects in the form of a transformation, as a result of which some constructive connection is established, and the transformation itself can be considered as a result of the action of an abstract cybernetic device. Constructive geometric modeling is a popular information tool for information processing in various applied areas, however, this tool cannot be appreciated without the presence of appropriate software systems and developed design techniques. Traditionally, constructive geometric modeling is used in the design of mechanical engineering, energy, aircraft and shipbuilding facilities, in architectural and design engineering. The need to study descriptive geometry at the university in recent years has something in common with the issues of mastering graphic packages of computer programs in the framework of the new discipline "Engineering and Computer Graphics". The well-known KOMPAS software product is considered the simplest and most attractive for training. It should be noted the important role of graphic packages in the teaching of geometric disciplines that require a figurative perception of the material by students. Against the background of a reduction in classroom hours, computer graphics packages are practically the only productive teaching methodology, successfully replacing traditional tools - chalk and blackboard.

New Information

CK2 is a Ser/Thr protein kinase overexpressed in many cancers. It is usually present in cells as a tetrameric enzyme, composed of two catalytic (α or α’) and two regulatory (β) subunits, but it is active also in its monomeric form, and the specific role of the different isoforms is largely unknown. CK2 phosphorylates several substrates related to the uncontrolled proliferation, motility, and survival of cancer cells. As a consequence, tumor cells are addicted to CK2, relying on its activity more than healthy cells for their life, and exploiting it for developing multiple oncological hallmarks. However, little is known about CK2 contribution to the metabolic rewiring of cancer cells. With this study we aimed at shedding some light on it, especially focusing on the CK2 role in the glycolytic onco-phenotype. By analyzing neuroblastoma and osteosarcoma cell lines depleted of either one (α) or the other (α’) CK2 catalytic subunit, we also aimed at disclosing possible pro-tumor functions which are specific of a CK2 isoform. Our results suggest that both CK2 α and α’ contribute to cell proliferation, survival and tumorigenicity. The analyzed metabolic features disclosed a role of CK2 in tumor metabolism, and suggest prominent functions for CK2 α isoform. Results were also confirmed by CK2 pharmacological inhibition. Overall, our study provides new information on the mechanism of cancer cells addiction to CK2 and on its isoform-specific functions, with fundamental implications for improving future therapeutic strategies based on CK2 targeting.

Effects Of Drought

In recent years, research on spermine (Spm) has turned up a lot of new information about this essential polyamine, especially as it is able to counteract damage from abiotic stresses. Spm has been shown to protect plants from a variety of environmental insults, but whether it can prevent the adverse effects of drought has not yet been reported. Drought stress increases endogenous Spm in plants and exogenous application of Spm improves the plants’ ability to tolerate drought stress. Spm’s role in enhancing antioxidant defense mechanisms, glyoxalase systems, methylglyoxal (MG) detoxification, and creating tolerance for drought-induced oxidative stress is well documented in plants. However, the influences of enzyme activity and osmoregulation on Spm biosynthesis and metabolism are variable. Spm interacts with other molecules like nitric oxide (NO) and phytohormones such as abscisic acid, salicylic acid, brassinosteroids, and ethylene, to coordinate the reactions necessary for developing drought tolerance. This review focuses on the role of Spm in plants under severe drought stress. We have proposed models to explain how Spm interacts with existing defense mechanisms in plants to improve drought tolerance.
