May Circuits ’23 was held on HackerEarth from 20 to 27.

The contest, which drew over 1 700 contestants from different countries in the world, set forth 8 problems including one challenge problem.

A student from Kim Chaek University of Technology (KUT) took the first place with a perfect score of 800. Three other KUT students ranked within the top 10 places including the 3rd and the 4th.

Not resting on their laurels, they are making redoubled efforts to make greater achievements next time.

Pak Kwang Ok, a lecturer at the Faculty of Distance Education, has been giving importance to questions and answers in online lectures on “Insulant Production Engineering”, thus making remarkable achievements.

Her lectures are mainly based on two-way-exchange of knowledge between a teacher and students, not one-way transfer of knowledge from a teacher to students. In her lectures, students, as masters of learning, are able to think independently about problems and solutions to them, thus improving their independent faculties of learning, inquiry and presentation.

First, at the beginning of lectures, she associates new materials with what they have alrealy learnt in order to make it possible for them to draw the gist of a new lecture.

For example, in the lecture on synthesis of polyamide resin, she reminds them of the concept of a polyester resin so that students can easily understand what polyamide resin is.

Second, she raises problems for several occasions of teaching to make a question-and-answer session between a teacher and students, or students and students.

In the lecture on synthesis of polyester resin, for instance, she gives a practical discussion question “Which of the two methods of synthesis of PET resin is more advantageous and practical in terms of industrialization, directness or indirectness?” after explanation of production process of PET resin so as to make students have a discussion and present their discussion results.

In this course, students bring up their own questions that they found difficult to understand while working at factories, and find answers to them through discussions.

As mentioned above, she has been making her teaching more effective and raising her students’ practical abilities through question-and-answer sessions.

A real-time distance education system has been developed by Kim Chung Min, a researcher at the Faculty of Distance Education.

It is an education support system that enables real-time audio-visual communication by computer devices such as IP cameras, USB cameras and microphones. It supports teaching planning, group discussion, desktop share, e-board share, streaming multimedia, online test, teaching evaluation, etc.

A real-time campus distance education system must be able to support a lecture for a large number of distributed students.

The proposed system supports various functions such as real-time communication via text, audio, camera display between an instructor and students, desktop share, streaming multimedia, e-board and sending files. In addition, it supports various types of teaching such as lecture, discussion and examination; lecture planning to set proper teaching methods, time and teaching steps; teaching evaluation to improve teaching methods through impersonal evaluation by students. It also supports group competition, discussion and presentation, foreign language audio-visual lectures and investigation of understanding through exams at any time.

The system can put the whole lecture process on IT footing and improve the density and effectiveness of teaching by employing superior teaching methods. Also, it can implement feedback coupling to develop new teaching methods through impersonal evaluation by students.

Ryom Chol Ung, a researcher at the Faculty of Mining Engineering, has been adding sci-tech knowledge of cross-disciplinary sciences to physical beneficiation of minerals so as to help his students to get a deep knowledge about it by means of preparation and discussion.

First, he has enriched the teaching content with cross-disciplinary sciences.

For instance, ways and methods of optical separation of minerals by differences from optical spectrum, a branch of cross-disciplinary sciences, were added to gravity separation of minerals that attaches importance only to the differences in the density of minerals, while such cross-disciplinary knowledge as cryogenic temperature physics, magnetic fluid, etc. were to magnetic separation of minerals.

Second, he has made preparations oriented to the acquisition of cross-disciplinary knowledge.

For example, he gives preparation tasks of consulting international scientific journals on the ways and methods of beneficiation of different kinds of minerals so that the students come to know that if ultraviolet separation is combined in the preseparation of scheelite, they can avoid excess grinding and reduce the amount of beneficiation reagents by using the differences from an ultraviolet luminescent colour and in the falling velocity of mineral particles in air media.

Third, he has consolidated student’s cross-disciplinary knowledge through debates and discussions.

Students have had a wide knowledge of several branches of cross-disciplinary sciences through discussions and debates on their tasks ― modeling, setting boundary conditions and result analysis for motion characteristics of mineral particles in a jigger, for example.

Paek Hyon I, a researcher at the Faculty of Applied Mathematics, has created a new teaching method by combining lectures with experiments by a statistical analysis program in her subject “Mathematical Statistics”.

Statistical analysis program SPSS (Statistical Package for Social Science) gives a variety of statistical principles and methods, so it is accepted as a powerful tool for analyzing and processing an enormous amount of statistical data with rapidity and high scientific accuracy. With a powerful graphical function, it produces not only numerical results but also intuitive statistical plots after statistical analysis.

First, she outlines discussion points before letting students study the basics for statistical analysis. For example, she reminds them of the definition of random variable and its distribution, characteristics, regression and linear regression, central limit theorem, etc. Then, she leads them to finding out from reference books what stochastic concepts and principles are latent in statistical data from objects.

Next, she teaches briefly how to run SPSS with an emphasis on the correct analysis of the results displayed on the output window with some tables and plots, and gives some application examples of several statistical analysis methods on necessary occasions of lectures so that they can easily learn how to use it.

In a lesson on estimation and testing of regression coefficients, for example, she gives theoretical contents and shows how to estimate the regression coefficients of a regression model and find important factors by SPSS.

On this basis, she gives students tasks to obtain real data and analyze it in groups. In other words, she has them obtain real data, analyze it using SPSS and present essays on the analysis processes.

In this way, students can understand difficult mathematical statistics more easily and intuitively in connection with reality, and they can develop their program application abilities as well.
