Introduction
This work covers the current results of the digital technologies integration into the educational process and the overview of the whole educational activities of Ecology and Industrial Safety department in Bauman Moscow State Technical University. The digital technologies integration project was developed by Y. V. Plastinin in 2014-2015 years. The update of Ecology and Industrial Safety department official website: http://e9.bmstu.ru (alias: mhts.ru, which represents the previous famous name of our university: Moscow High Technical School) was the reason of this project creation.
According to the implemented changes the updated website provides the access to: • Youtube channel [1] of the department that contains the best reports from conferences (1), graduate qualification works (2), main courses online lectures (3), online introduction videos to laboratory works (4); • presentations of lectures and seminars (5); • educational-methodical material (6); • other informational materials (7). Moreover, the project includes the development of mobile applications (8), laboratory works online timetable management system (9). The latter was proposed by M. V. Simakov.
The online lectures (3) and presentations (5) development was integrated into The Program of the online courses development and integration into the educational process in Bauman Moscow State Technical University based on the Open BMSTU [2] platform in 2018-2019. The results of the elements (3) and (5) integration into the educational process of spring 2018/2019 semester are described in more details below.
Let us look briefly into the other elements of the project.

Main part
Elements (1)-(2) represent online video library of the department. The creation of Crisis Situations Management Center (CSMC) allowed to record and store conferences reports, graduate qualification works on video server [3,4,5]. These materials were edited and uploaded on the Youtube channel [1]. They can be used during consultations, students' research work, preparation to student contests. Elements (6)- (7) are the basic ones to be used for high-class university websites. It is important to mention that materials were being collected during all these years from the website creation time in 2000 up to now. It is crucial for materials to be continuously updated.
Laboratory works online timetable management system for Life Safety course was developed and integrated into the educational proccess in 2018-2019 [6]. The students authorized by lecturers register their groups for the laboratory works: two times during the semester. The system administrator sets the critical number of students in the group while when being exceeded automatically divided into two groups. The administrator also sets the planned number of hours for each lecturer, so each lecturer can keep control of the total number of hours. If there is no any record in the timetable made by students the lecturer cannot confirm the laboratory work. The timetable of autumn semester 2019/2020 was the first pilot to be done though the introduced system. The system is not linked to particular course and can be used for laboratory works timetable management for any course.
Life safety course online introduction videos to the laboratory works (4) were created in 2018 [7]. Students of the department took part in the development of these videos. The created videos do not substitute printed methodical materials because they do not contain the work order instructions. They substitute the introduction and theoretical part. The authors of printed methodical materials took part in the development of the scenarios of these videos.
Video was created according to the approved story-board scenario in Adobe Premier application. The audio coverage (text) was done by the students of the department.
The online lectures (3) of the course Life safety was developed according to the Program of the development and introduction of online courses into the educational process of Bauman Moscow State Technical University. Online lectures were created the same way as the online introduction videos (4). Story-board scenarios of lectures were devoted to different topics such as noise protection, vibration protection, illumination and so on and were created by the leading specialists of the department and compiled and edited by Y. V. Plastinin, who has great experience in the development of multimedia projects. Students of the department took part in the process as well. The scenario included text of the lecture linked to the illustrations: photo, video, pictures, graphics, formulas and so on. Each scenario was reviewed and corrected to be finally signed off. The videos of A. S. Kozodaev lectures were recorded in a studio with special green background. Then the video was edited using keying method and synchronized with frames of the illustrations in Adobe Premier application.
The authors of the online course could not use the widely spread textbook «Life safety» under the edition of Belov S. V. [8] written in our department mostly by the same authors of online course. The key reason was that multimedia presentation requires another approach for the material presentation. At the same time authors of online course leveraged the great experience gained during teaching the course of Life safety in the department. Teaching experience of the authors from Bauman Moscow State Technical University [9][10][11] and authors from international institutions [12][13][14][15][16][17][18][19][20] was also considered. It is important to mention that the course creation was initiated by S.V. Belov (1932Belov ( -2013, who was the head of our department from 1976 till 2007 [21].
Life safety Online course consists of 16 lectures and is available on the youtube channel and the department website [1,22]. It is also available on the platform Open BMSTU [2].
More than 40 % of the students watched these lections at the beginning of the course in the 2018/2019 which is quite high.
The Life safety course ppt-presentations of lectures and seminars (5) unlike online lectures have to consider the specialization of students. The webpages of the course are available only to authorized students and are created individually for each lecturer [23]. The lecturer gives the access to his personalized page at the beginning of the course and closes access when the course ends. Besides the presentations of lectures and seminars the lecturer can upload any supplementary material, such as summary of the most complicated lectures, tasks for the seminars and examples of their solutions.
The choice of Life safety online course realization among of all others courses of the department, is quite evident.
According to the Federal State of Educational Standards for Higher Education the Life safety course has to be mandatory course for all students and has to be part of the main educational plan for bachelors and specialists of all specializations.
Nowdays many universities in Russian Federation have developed their own online courses of this discipline (SPbPU, NUST MISIS, TSU (Tomsk), SPbU and so on).
NUST MISIS, TSU (Tomsk), SPbU have included their courses to the National Platform of Open Education.
The main purpose of studying the Life safety course is the development of the professional safety culture (noxological culture), which means: • the willingness and ability of the individual to use the acquired combination of knowledge, abilities and skills for the safety provision in the field of professional activity; • the way of thinking and value prioritization in which safety is considered as priority.
The content of online course corresponds the requirements of Federal State Educational Standards of Higher Education, Self established educational standards of higher education, Approximate program of the course, work programs of Life safety course of Bauman Moscow State Technical University.
The Life safety course is taught according to the educational programs of bachelors and specialists for all specializations and consists of three modules: 1) A person and technosphere; 2) The identification of hazards, methods and ways of protection; 3) Emergency and civil defense.
The structure of the course is presented in the Fig. 1. The contents of the course is presented in table 1.

There were 2 ways of how the online course was used by different lecturers: 1) online lectures, presentations and summaries were available for students before the lessons; presentation were used during the lesson; online lectures were demonstrated fully or partly; 2) online lectures were available for students before the lessons, presentations and summaries were available only after the lessons; presentations were used as supplementary material in the usual lecture; online lectures were not demonstrated during the lessons.
The best approach can not be defined yet as the comparison of students results from different groups was not carried out.
The check points were done in the test format on the platform Open BMSTU [2]. The tasks and questions were developed based on the ones already shown during seminars and topics covered during lectures.
The students had access to the tests via their accounts, being active during the semester. By the way, in our opinion the double authorization is more effective: the authorization of the device used for doing tests and the authorization of student. In our opinion the use of the smartphones for such activity is not appropriate. Moreover, the test system has to be modified: the option of the second try test is to be added. The availability of the test that can be done for the second time has to be controlled by the lecturer. The results of the tests should have the different max points as it is the second try.
The homework and laboratory works were almost unchanged in comparison to the usual way of teaching the course. Although the students had the opportunity to get ready for the laboratory works by watching online introduction videos [7].
The lectures and seminars required computers and devices for slides and video demonstration (for example, projector). Computer classes were required for the control tests. By the way, the necessity of the blackboard has not disappeared as the students often have questions that demand the detailed illustrative response that can de hardly predicted.
Unlike the usual lessons, online seminars were carried out in different classes: control tests in computer classes, ordinary seminars in ordinary classes which led to some organization problems.

Conclusions
The pilot of the online course introduction in the educational process continues in 2019-2020: the number of students and lecturers, participating in experiment, grows, the presentations are constantly improved, updated and adopted to particular specialization of the students. The next special Ecology of biosphere course is being developed at the moment.
