With the advent of the Fourth Industrial Revolution, the liberal arts education of universities has been called for fundamental innovation in its content and methods. H university has continuously made efforts to improve its general education curriculum with the goal of satisfying students' needs as well as the demands of the times. Its efforts can be summarized as the harmonization of competency-based education and the traditional liberal arts education. In more detail, it has tried to meet the demands of Ministry of Education which requests each university to establish its general education system focusing on key competencies. Simultaneously, it also radically changed its education system based on the guidelines of the Korea National Institute for General Education(KONIGE). The starting point of those changes was the basic consulting by KONIGE in 2017. According to the consulting report, H university introduced comprehensive and overall revision of its liberal arts education curriculum, increasing its liberal arts credit requirements from 22 to 28 credits in 2019. It has also reorganized and reclassified its liberal arts courses by introducing distributive elective classes. In 2020, in accordance with the guidelines of the Ministry of Education, H university altered its curriculum once more in order to establish a competency-based general education curriculum. Under the new curriculum, all requirement subjects are completely matched with key competencies of H university. It also includes newly opened courses and subject areas such as "Social Service" and "Global Citizenship." Through these changes, H university hopes that its general education contributes to fostering students equipped with key competencies, who can face actively this challenging period.

An objection of this study is to develop a measuring circuit of a gauge using radioisotope for compaction control. The gauge developed in this study makes use of radioisotope with the activity exempted from domestic atomic law and consists of measuring circuits for gamma-rays and thermal neutrons, a high voltage supply unit, and a microprocessor. To obtain meaningful numbers of pulse counts, parallel five and two circuits are provided for gamma-rays and thermal neutrons, respectively. Being simple in electrical characteristics of G-M detector for gamma-rays, pulses are counted through only a shaping circuit. Very small pulses generated from He- 3 proportional detector for thermal neutrons are amplified to the maximum of 50 [dB] and a window comparator accepts only pulses with meaning. To minimize effects of natural environmental radiation and electrical noise, circuits are electrostatically shielded and pulses made by ripples are eliminated by taking frequency of high voltage supplied to the circuit and pulse height of ripples into consideration. One-chip microprocessor is applied to process various counts, results are stored and the gauage is made capable to communicate with PC. Enough and meaningful numbers of pulses are counted with the prototype gauage for compaction control.
