Feedback on the lectures of “Biostatistics” provided by NWSMU
I am a first-year student of graduate school of biomedical sciences, department of disaster andradiation medical sciences master course, Nagasaki University, Mariya Ivanchykava.
During my educational program, I had a course of “Biostatistics” held by Prof. Sviatoslav
Plavinskij.
Even though Biostatistics was a difficult course for me, Professor’s explanation was availableand clear. Lectures included valuable and important information that could be used during
further Master course. Prof. Sviatoslav Plavinskij kindly answered all our questions during thelectures and helped us to understand biostatistics deeply not only theoretically but also inpractice using SAS OnDemand for Academics. I never heard about this system before and I
was pleased to get to know about it. Professor Plavinskij showed us how to work with theprogram and now I can use is it in my research work.
However, I was a little bit upset because I could not meet Professor personally and visit
NWSMU in Saint Petersburg this year due to the quarantine and COVID-19.
Nevertheless, I think one week is an extremely short period of time to memorize such amount of
information and I would like to have more lectures and especially practice in a longer time tounderstand the course better because as I said above materials provided by professor are reallyneeded and useful in my future surveys.
In conclusion, I would like to say that I am really grateful to the professor for the course ingeneral and for teaching us how to use SAS OnDemand for Academics in particular.

I am a first year student of Disaster and Radiation Medical Sciences Master course. Recently, I
have finished the course of «Biostatistics» which was performed by Professor Sviatoslav
Plavinskij. During the classes I was introduced the optimal methods for collection, processing,maintaining, analysis and presentation of data. Moreover, I obtained practical knowledge on how
to use statistical software, namely “R” and “SAS on Demand for Academics”. Professor showed
us how to use the software on relevant and concrete examples. These skills are essential for
representative statistical analysis and will help me to conduct a research for the Master thesis.
Furthermore, ability to use mentioned above statistical and data analysis systems is required forany qualified person working in biomedical sciences.
Biostatistics is a continually developing and complicated subject. However, Professor Plavinskij
found a comprehensive way how to explain it. All lectures were clear and easily understandable.
Professor illustrated the difficult concepts using tables and graphs, answered every arisenquestion and provided additional information when necessary. Unfortunately, I did not have apossibility to meet Professor personally because of COVID-19 pandemic. Despite the fact thatthe course was performed on “Zoom” I did not identify any problem with communication.
Furthermore, Professor created a good working climate and effectively organized our classes.
In conclusion, I would like to express my gratitude to the Nagasaki University, North-WesternState Medical University and especially Professor Sviatoslav Plavinskij for the given opportunity
to study Biostatistics under Professor’s supervision.

Feedback on course “Biostatistics” from student Aizhan Zabirova
Professor Sviatoslav Plavinskij
Semester: Winter 2021

Professor Plavinskij is a great professor. I can tell that he puts a lot of time and effort into thiscourse through his attention to detail and his comments. He really does his best to give us a
deep and detailed knowledge.
Before the biostatistics course, I did not know about the SAS system and program. Now I
find it very useful, especially for our future articles and for processing large amounts of data.
Since the system already includes ready-made formulas, their accuracy and fidelity cannot bequestioned. Thanks to the professor's desire to teach us this program, we mastered the basic
working tools. At the moments when we had questions, the professor was patient andclarified incomprehensible points to every student.
I would recommend lectures provided by Professor Plavinskij to other students. He is very
personable and enjoys teaching. He also takes the time and energy to improve and make surethat we have a great learning experience. This course was incredibly valuable.
In class, I thoroughly appreciated the use of concrete examples. I continued to use andimprove knowledge in SAS program.

Feedback Biostatistics

It is no secret that since the pandemic has penetrated into our daily lives, all lessons
have moved to a online format.
I was worried that a lesson like Biostatistics would be hard to learn through zoom.
But the lesson taught by Professor Plavinsky was clear and fascinating. All thematerial presented in the lessons was well explained by the professor.
The various statistical programs were also well explained in terms of the differences
and advantages between the SAS and R programs.
They are very useful and easy to use and will become a very useful tool in scientificwork in the future. And all this thanks to Professor Plavinsky.

The lectures on Biostatistics provided by the North-West State Medical University were extremelyinformative. The presentations were structured and understandable, which is very important when
you study in another language. Professor Plavinsky in rather limited amount of time managed toprovide a lot of valuable and relevant information on the subject. I learnt a lot of new things, inparticular, the basics of working with epidemiological software, which will be useful in my future
researches. The manner in which the information was explained showed SAS software as a helpful
tool, rather than something overcomplicated. Additionally, I appreciate that Professor Plavinsky
pointed out ways for further knowledge improvement: reliable authors and trustworthy internet
sources.Professor Plavinsky is a wonderful professor. I believe that study with
him is a great experience to us. Although all our courses must be
conducted online due to the COVID-19. Professor Plavinsky still
explained each point carefully for us. Especially teach us to use the SASsystem. I think this will play a very important role in our future study andresearch.
In the course of the professor Plavinsky's class, he will carefully stateeach key point, and when we have any problems when using SAS system,he will explain clearly and show us the correct steps very intimately. Thisis very important.

All in all, I would like to thank the professor Plavinsky for his patienceand enthusiastic lectures. Thank you very much.
