Many people in the DPRK are contributing to improving the country’s ecological environment. Among them is Kim Kyong Suk, PhD, Associate Professor and head of the greening technology department of Pyongyang College of Urban Management.
Seven years ago she published a paper “Study on Biological Properties of Aegukphul and Its Vegetative Propagation and Suitable Cultivation Soil” and introduced her research findings into the Tudan Duck Farm, Pyongyang Ostrich Farm and other farms in different parts of the country. For her contribution to solving the problem of domestic animal feed she achieved a doctorate in 2018.
Recently, she has developed an environment-friendly insect killing lamp that meets the local specific conditions, thus contributing to improving the country’s ecological environment.
Nowadays, the worsening global warming and its ensuing climate crisis give rise to serious ecological changes, entailing the spontaneous presence of various kinds of harmful insects.
The same is the case with the DPRK.
So Kim decided to manufacture a device to kill insects by a physical method while giving no negative impact on ecosystem, and set about its development.
She found it important to have a deep understanding of their properties.
While studying the physiological characteristics of harmful insects, including mosquitoes and flies, she learned about their likes and dislikes and food chain.
She tried hard to find out a way of easily decoying and killing harmful insects by combining LED lamps emitting near-ultraviolet rays and photocatalyst panels that decompose and remove various pollutants as insects do not resist the temptation of lights and smells.
In the course of this, she developed the method of killing harmful insects by electrical pulse stimulator, a support program for predicting the appearance of harmful insects and killing them, and a lamp for purifying the air and killing insects.
The insect killer that has no negative impact on urban beautification was ranked first at the sci-tech presentation and exhibition for improving the ecological environment of the capital city held in March.
For nearly 20 years she has written more than 10 textbooks and reference books including “Flower Cultivation Techniques” and “Botany” and published more than 30 essays, which made a tangible contribution to education.
