Achievements in the area of automated ultrasonic control of quality of rails, solid-rolled wheels and tyres, wheels magnetic powder crack detection, carried out at JSC EVRAZ NTMK. The 100% nondestructive control is accomplished by automated control in series at two ultrasonic facilities RWI-01 and four facilities УМКК-1 of magnetic powder control, installed into the exit control line in the wheel-tyre shop. Diagram of location, converters displacement and control operations in the process of control at the facility RWI-01 presented, as well as the structural diagram of the facility УМКК-1. The automated ultrasonic control of rough tyres is made in the tyres control line of the wheel-tyre shop at the facility УКБ-1Д. The facility enables to control internal defects of tyres in radial, axis and circular directions of radiation. Possibilities of the facility УКБ-1Д software were shown. Nondestructive control of railway rails is made at two facilities, comprising the automated control line of the rail and structural shop. The УКР-64Э facility of automated ultrasonic rails control is intended to reveal defects in the area of head, web and middle part of rail foot by pulse echo-method with a immersion acoustic contact. The diagram of rail P65 at the facility УКР-64Э control presented. To reveal defects of the macrostructure in the area of rail head and web by mirror-shadow method, an ultrasonic noncontact electromagnetic-acoustic facility is used. It was noted, that implementation of the 100% nondestructive control into the technology of rolled stuff production enabled to increase the quality of products supplied to customers and to increase their competiveness.

This article explores a commonly ignored aspect of Japan–North Korean relations: the Japanese factor in the making of Korean socialism. Korea was indirectly influenced by the Japanese Jiyuminken Movement, in the 1910s–1920s serving as a stepping-stone for the creation of a Japanese Communist Party. Wartime mobilization policies under Japanese rule were continued and expanded beyond the colonial era. The Juche ideology built on tendencies first exhibited in the 1942 Overcoming Modernity Conference in Japan, and in the 1970s some Japanese leftists viewed Juche as a humanist Marxism. Trade between Japan and North Korea expanded from 1961 onwards, culminating in North Korea’s default in 1976, from which point on relations soured between the two countries. Yet leaders with direct experience of colonial rule governed North Korea through to the late 1990s.
