A Design Support Tool Set for Interface Circuits Between Synchronous and Asynchronous Modules

In this paper, we propose a design support tool set for interface circuits between synchronous and asynchronous modules. To facilitate the design of interface circuits between synchronous and asynchronous modules, the proposed tool set generates interface circuits and design constraints based on a predefined communication scheme. In addition, the proposed tool set performs timing verification and delay adjustment to guarantee the operations of the generated interface circuits. In the experiment, we evaluated the latency and overhead of the generated interface circuits. The latency and handshake overhead of the interface circuits generated by the proposed tool set depend on the cycle time of the receiver module. In addition, we designed a system which consists of a synchronous RISC-V processor and an asynchronous multilayer perceptron (MLP) circuit using the proposed tool set. The energy consumption of the system was reduced by 34.0% compared with a system which uses a synchronous MLP circuit.

Socially Oriented Information Technology for Reducing the Environmental Impact of Mines and Metallurgical Enterprises

The proposed socially oriented information technology is based on the integration of diversification and technological processes for the creation of additional products and infrastructure, by stepwise structural synthesis of waste processing and land reclamation. The technology relies on empirical assumptions, theoretical principles, models of the decrease in environmental impact, assessments of the requirements, practical results, and verification criteria. The main approaches to decreasing the environmental impact include prevention of environmental damage; the introduction of a complete resource-utilization cycle; reconciliation of the interests of state agencies, investors, property owners, and other stake holders; and the stepwise integration of waste processing, recultivation of degraded land, and the creation of social infrastructure. The conceptual model for decreasing the environmental impact makes coordinated use of the primary and secondary products of waste processing and land restoration, with subsequent infrastructure creation. The outcomes of socially oriented information technology are specific, interpretable, verifiable, reliable, complete, and consistent. On the basis of the proposed tool set, scenarios are developed for improving the environmental conditions in the city of Novokuznetsk, which is located in the vicinity of metallurgical enterprises. In these scenarios, industrial wastes are used in the production of raw materials for the steel industry, building materials (bricks, concrete additives), and agricultural fertilizer. Predictions are made up to 2037, in terms of economic impact, area of recovered land, environmental pollution by productive activities, population of the region, relevant standards, and the pollution prevented per capita. Construction of the new system is planned for 2019 and 2020, with operation in 2021. Stepwise construction of the social infrastructure will begin in 2033. Simulation indicates the annual growth in predicted indices under the various scenarios, on account of synthesis of waste processing and land restoration, as well as decrease in the pollution thanks to low-waste and zero-waste production.

THE APPLICATION OF MODERN HR- TECHNOLOGIES AS АN EFFECTIVE TOOL IMPROVEMENT OF PERSONNEL MANAGEMENT ENTERPRISES IN UKRAIN

Relevance of the research topic. The importance of studying HR-technologies in the system of personnel management has become paramount for modern domestic enterprises. Problem setting. There is a critical need to develop and implement relevant HR-technologies as practical tools in effective personnel management practices at domestic enterprises. Recent research and publications analysis. Within the national research papers exploring effective personnel management methods we should mention the following scholars: L. Balabanov O. Vasilieva, Z. Imasheva, H. Shchokin, O. O. Petrashchak, O. M. Rudenko, L. M. Usachenko, S. V. Shturkhetskyi. Among the foreign authors considerable contribution was made by John Berzin, D. Diakov, P. Loikova, Yu. Pass, O. Svergun, P. Ward D. Ulrich etc. Unresolved issues. Current trends in personnel management at domestic enterprises reveal the low quality of employees and management staff replacement and development process, thus triggering the need to work out new efficient approaches and tools to enhance the HRM system. Research objective. The paper is aimed at developing a well-grounded framework of personnel management optimization system through the use of the proposed tool set. Research findings. The personnel management system is a cornerstone in any enterprise management paradigm, since its effectiveness influences the overall business performance and the achievement of a company objectives. Domestic enterprises in their human resources management strategies were mainly affected by their own experience and partial transfer of some elements of advanced foreign personnel management practices and techniques. The paper substantiates the transition from the traditional personnel management system to the contemporary concept of human resources management through the use of modern tools aimed at continuous improvement of technology, subject to turbulent environments challenges. Conclusion. The introduction of modern HR-technologies is a critical and reliable basis for management process optimization which enables to enhance the existing approaches to personnel selection at domestic enterprises.

고립화 수준을 검증하기 위한 트랜잭션의 시험

데이터베이스 응용 프로그램들은 DBMS가 관리하는 데이터베이스를 동시에 접근하기 때문에 동시성 문제가 발생하며 이를 해결하기 위해서 대부분의 상업용 DBMS들은 고립화 수준을 설정할 수 있게 한다. 데이터베이스 응용 프로그램을 구성하는 트랜잭션들의 고립화 수준에 따라서 데이터베이스의 일관성이 위반될 수도 있기 때문에 트랜잭션의 고립화 수준의 검증은 중요하다. 본 논문은 트랜잭션의 고립화 수준 설정 오류를 검증하기 위한 시험 도구를 제안하고 프로토타입을 구현한다. 시험 도구는 ESQL/C 프로그램을 분석하여 고립화 수준을 검증할 수 있는 코드를 추가하여 시험 트랜잭션을 실행시키고 고립화 수준의 오류를 검출할 수 있게 한다. Concurrency and synchronization problems are often caused by database applications concurrently accessing databases managed by DBMS. Most commercial DBMSs support isolation levels to resolve these problems. Verification of isolation levels are most important because consistency and integrity constraints of the database can be violated according to isolation levels of transactions that consists of database applications. We propose a test tool set to verify and reveal faulty settings of isolation levels and implement a prototype of the test tool set. The proposed tool set analyzes the SQL statements of ESQL/C programs, attaches the test codes to verify isolation levels, runs the test transactions and detects errors.
