The process of creating multimedia message is a very specific creative act, a kind of art with universal characteristics, but with its unique tendecieses. In its ideal form, art usually targets the indefinite, while the message follows predictable targets in the short period of time. The art of creating a successful message is in decoding the meaning of that message. The essence of concept of multimedia message is hidden in its formula because the whole physionomy of that message and the volume of expected effect depend on the formula. It is the base for building up tipological, graphic and music concepts. Global development of informational and comunicological technologies catalyzes diversificiation of platforms for distribution of audiovisual contents. multimedial message allows more supstantional contents, and its main goal is to convince a reciptient. modern technologies transfer the pedagogical knowledge and form contemporary visual culture within the recipients. The use of contemporary technologies asks for particular principles. This paper is focused on didactical principles used in the process of creation of multimedia messages.

This paper reports an experience of teaching Computational Thinking (CT) to K-12 educators through an online Scratch programming short course. The meeting of CT and modern technologies is extending the use of coding in K-12 education. An essential requisite for this to prosper is the teacher prepa- ration. However, most current teacher training programs fail to supply with pedagogical knowledge for educators to teach CT. Thus, it is critical to present CT to K-12 teachers, providing proper conditions to learn and use its concepts. In this context, this work aimed to design and implement an online Scratch programming course for K-12 educators. Results suggested that using Scratch to teach CT for K-12 educators is adequate, and analyzing educators context when presenting tutorial Scratch projects is relevant.

Myanmar is an agricultural based country and 70% of total population is relied on Agricultural sector. On the other hand, Agricultural sector is affected by climate changes especially in the Costal and Delta Regions of Myanmar. Besides, Myanmar is currently transforming towards the democratic nations and the government is supporting to upgrade Agricultural Sector not only for local farmer but also throughout the country. There can be found that the lack of education, training and seminar, technological knowledge, modern technologies, inadequate modern farming methods and insufficient infrastructure respectively. If Government can provide effectively agricultural techniques, modern technologies and climate change policies on the challenges and difficulties, it will surely become a developed country within a short period.

In modern economic conditions, there is an active transformation of interaction between economic entities and consumers, which occurs through the involvement of new tools that cause the onset of the industrial revolution (Industry 4.0). The increase in the scope of the Internet and the expansion of the digital space largely provides an opportunity to conveniently obtain information about works, services, goods and their cost. In such a situation, when the diffusion of products, goods, works and services is more active, and the stage of life associated with sales is characterized by an increasingly short period, specialists in the field of sales activities are focused on involving new opportunities on the Internet in order to promote them as productively as possible. the article presents the key types of social media used as objects of marketing activity. The article analyzes information about the income of companies due to the placement of advertising messages in social networks, and also presents the characteristics of global social media that have a positive experience of penetration into the world market. The article reveals the main advantages of modern technologies of product promotion in the market and identifies the difficulties that arise in its implementation. The main purpose of this study is to identify a modern tool that provides businesses with the opportunity to carry out stable sales activities of manufactured goods and expand the sales market based on the involvement of digital technologies in this business process.

During the last 10 years, the writer has presented evidence indicating that the Moon was captured by the Earth and that the large collisions with its surface occurred within a surprisingly short period of time. These observations have been a continuous preoccupation during the past years and some explanation that seemed physically possible and reasonably probable has been sought.

AbstractStructural effects of the resonance with the mean motion of Jupiter on the system of short-period comets are discussed. The distribution of mean motions, determined from sets of consecutive perihelion passages of all known periodic comets, reveals a number of gaps associated with low-order resonance; most pronounced are those corresponding to the simplest commensurabilities of 5/2, 2/1, 5/3, 3/2, 1/1 and 1/2. The formation of the gaps is explained by a compound effect of five possible types of behaviour of the comets set into an approximate resonance, ranging from quick passages through the gap to temporary librations avoiding closer approaches to Jupiter. In addition to the comets of almost asteroidal appearance, librating with small amplitudes around the lower resonance ratios (Marsden, 1970b), there is an interesting group of faint diffuse comets librating in characteristic periods of about 200 years, with large amplitudes of about±8% in μ and almost±180° in σ, around the 2/1 resonance gap. This transient type of motion appears to be nearly as frequent as a circulating motion with period of revolution of less than one half that of Jupiter. The temporary members of this group are characteristic not only by their appearance but also by rather peculiar discovery conditions.

AbstractThe nongravitational motion of five “erratic” short-period comets is studied on the basis of published astrometric observations. We present the precession models which successfully link all the observed apparitions of the comets: 21P/Giacobini-Zinner, 31P/Schwassmann-Wachmann 2, 32P/Comas Solá, 37P/Forbes, and 43P/Wolf-Harrington. We used the Sekanina's forced precession model of the rotating cometary nucleus to include the nongravitational terms into equations of the comet's motion. Values of six basic parameters (four connected with the rotating comet nucleus and two describing the precession of spin-axis of the nucleus) have been determined along the orbital elements from positional observations of the comets. The solutions were derived with additional assumptions which introduce instantaneous changes of modulus of reactive force,Aand of maximum of cometary activity with respect to perihelion time. The present precession models impose some contraints on sizes and rotational periods of cometary nuclei. According to our solutions the nucleus of 21P/Giacobini-Zinner with oblateness along the spin-axis of about 0.32 (equatorial to polar radius of 1.46) is the most oblate among five investigated comets.

AbstractFrom the established dependence of the brightness decrease of a short-period comet dependence on the perihelion distance of its orbit it follows that part of the surface of these cometary nuclei gradually covers by a refractory crust. The results of cometary nucleus simulation show that at constant insolation energy the crust thickness is proportional to the square root of the insolation time and the ice sublimation rate is inversely proportional to the crust thickness. From laboratory experiments resulted the thermal regime, the gas productivity of the nucleus, covering of the nucleus by the crust, and the tempo of evolution of a short-period comet into the asteroid-like body studied.

AbstractThe Oort cloud probably is the source of Halley-type (HT) comets and perhaps of some Jupiter-family (JF) comets. The process of capture of Oort cloud comets into HT comets by planetary perturbations and its efficiency are very important problems in comet ary dynamics. A small fraction of comets coming from the Oort cloud − of about 10−2− are found to become HT comets (orbital periods < 200 yr). The steady-state population of HT comets is a complex function of the influx rate of new comets, the probability of capture and their physical lifetimes. From the discovery rate of active HT comets, their total population can be estimated to be of a few hundreds for perihelion distancesq <2 AU. Randomly-oriented LP comets captured into short-period orbits (orbital periods < 20 yr) show dynamical properties that do not match the observed properties of JF comets, in particular the distribution of their orbital inclinations, so Oort cloud comets can be ruled out as a suitable source for most JF comets. The scope of this presentation is to review the capture process of new comets into HT and short-period orbits, including the possibility that some of them may become sungrazers during their dynamical evolution.

AbstractA Pareto distribution was used to model the magnitude data for short-period comets up to 1988. It was found using exponential probability plots that the brightness did not vary with period and that the cut-off point previously adopted can be supported statistically. Examination of the diameters of Trans-Neptunian bodies showed that a power law does not adequately fit the limited data available.
