Real-time hybrid testing (RTHT) involves virtual splitting of the structure into two parts: physical substructure that contains the key region of interest which is tested in a laboratory and numerical substructure that contains the remaining part of the structure in the form of a numerical model. This paper numerically assesses four step-by-step integration methods (Central difference method (CDM), Operator splitting method (OSM), Rosenbrock based method (RBM) and CR-integration method (CR)) which are widely used in RTHT. The methods have been assessed in terms of stability and accuracy for various realistic damping ratios of the physical substructure. The stability is assessed in terms of the spectral radii of the amplification matrix while the accuracy in terms of numerical damping and period distortion. In order to evaluate the performance of the methods, five carefully chosen examples have been studied - undamped SDOF, damped SDOF, instantaneous softening, instantaneous hardening and hysteretic system. The performance of the methods is measured in terms of a non-dimensional error index for displacement and velocity. Based on the error indices, it is observed that OSM and RBM are robust and performs fairly well in all the cases. CDM performed well for undamped SDOF system. CR method can be used for the system showing softening behaviour. The error indices indicate that accuracy of OSM is more than other method in case of hysteretic system. The accuracy of the results obtained through time integration methods for different damping ratios of the physical substructure is addressed in the present study. In the presence of a number of integration methods, it is preferable to have criteria for the selection of the time integration scheme. As such criteria are not available presently, this paper attempts to fill this gap by numerically assessing the four commonly used step-by-step methods.

The aim of the study is to assess the asymmetry of influence of factors of economic growth of national economies, which are included in the integration. Unlike previous research, the scientific significance of the obtained results consists in the use of a new method of study - external demand as a factor of economic growth, disaggregated into two components. The first is net exports mutual trade in goods within integration associations. The second is net exports of foreign trade in goods outside the integration. By use of these methods we have evaluated the contribution of these factors on economic growth of the Customs Union and the Common Economic Space (CU/CES), as well as Kazakhstan, Russia and Belarus. In the conducted analysis of scientific research was based on the fact that the economies of the member (CU/CES) are very different in scale, economic potential and volume of foreign trade. Based on this research we conclude: integration is developing successfully and efficiently only with the rise of the national economies of the member countries; to enhance economic growth and competitiveness of the countries of the Eurasian integration it is necessary to increase the volume of mutual trade of member countries of this integration.

과학 공학 분야의 사이버 인프라스트럭쳐는 다양한 도메인에서 수행되는 연구 활동을 통해서 얻어지는 다양한 형식의 데이타들뿐만 아니라 이런 데이타를 저장 관리하기 위한 이질적인 저장소들의 통합이 요구되고 있다. 데이타 통합 작업의 어려움은 다음과 같다: (1) 시스템 독립적인 다중 데이타 스키마 지원, (2) 다양하게 변화하는 스키마들의 쉬운 관리, (3) 직관적인 스키마 맵핑. 이 같은 문제를 해결하기 위해서, 우리는 XML Schema를 이용해서 과학 분야의 데이타 모델을 정의하고 RDF기반의 스키마 맵핑을 이용해서 의미적으로 통합할 수 있는 새로운 방법을 제안한다. XML Schema기반의 데이타 모델 정의 방법은 실험 데이타들을 과학자들이 직관적이고 간편하게 표현 할 수 있게 해주며, 이 데이타 모델은 많은 시스템에서 사용중인 XML DBMS를 그대로 이용할 수 있는 장점이 있다. 또한, 스키마 맵핑을 위해서 RDF로 구축된 온톨로지를 이용해서 XML Schema로 정의되어 있는 스키마의 구조적인 관계를 정의하고, 맵핑 정보를 이용해서 통합 질의를 수행한다. 우리는 제안 시스템의 프로토타입을 토목 공학 분야 프로젝트인 KOCED에 적용하였다.

The article identifies areas for effective management of innovative development. The competitiveness of the economy in the context of European integration and economic security is assessed. The level of innovative economy of some countries of the world is analyzed. The issue of attracting foreign investors to stimulate innovative production in Ukraine is raised. It is identified the need for the formation of an updated state policy capable of providing innovative development and improving the competitive position of the state in international rankings. Emphasis is placed on the need to form a critical mass of managers-civil servants capable of developing, implementing and monitoring the policy of innovative development of entrepreneurship.

이 연구에서는 영재교육종합 데이터베이스(GED)에서 제공하는 초등 과학영재교육 프로그램 수상작을 과학적 창의성 관점에서 분석하였다. 이를 위해 해당 분석 기준을 개발한 뒤 우수 프로그램 55개에 포함된 840개의 탐구활동을 분석하였다. 연구 결과, 과학적 창의성 요소 5가지 중, '과학적 탐구기능', '과학 지식 내용', '창의적 사고'가 많이 포함되었다. 하지만 '문제해결력'과 '공통 요소'는 비교적 적게 포함되어 있었다. 통합의 측면에서는 2가지 요소의 통합과 3가지 요소의 통합이 자주 나타났으며, 통합이 없는 유형도 자주 나타났다. 4가지 요소의 통합이나 5가지 요소의 통합은 적게 나타났다. '과학 지식내용', '과학적 탐구기능', '창의적 사고' 등이 다른 요소들과 함께 통합되는 빈도가 높았다. 그러나 '공통 요소' 또는 '문제해결력'이 다른 요소와 통합되는 경우는 적게 나타났다. 이에 대한 교육적 시사점을 논하였다.

Landslides pose significant threats to many countries globally, yet the development and implementation of effective landslide early warning systems (LEWS) remain challenging due to multifaceted complexities spanning scientific, technological, and political domains. Addressing these challenges demands a holistic approach. Technologically, integrating thresholds, such as rainfall thresholds, with real-time data within accessible, open-source software stands as a promising solution for LEWS. This article introduces LandScient_EWS, a PHP-based program tailored to address this need. The software facilitates the comparison of real-time measured data, such as rainfall, with predefined landslide thresholds, enabling precise calculations and graphical representation of real-time landslide advisory levels across diverse spatial scales, including regional, basin, and hillslope levels. To illustrate its efficacy, the program was applied to a case study in Medellin, Colombia, where a rainfall event on August 26, 2008, triggered a shallow landslide. Through pre-defined rainfall intensity and duration thresholds, the software simulated advisory levels during the recorded rainfall event, utilizing data from a rain gauge positioned within a small watershed and a single grid cell (representing a hillslope) within that watershed. By identifying critical conditions that may lead to landslides in real-time scenarios, LandScient_EWS offers a new paradigm for assessing and responding to landslide hazards, thereby improving the efficiency and effectiveness of LEWS. The findings underscore the software's potential to streamline the integration of rainfall thresholds into both existing and future landslide early warning systems.

Design that is emotionally gratifying is a product design that has been produced by considering user's emotions to give satisfaction through a compositive integration of environmental elements, user's psychological and cognitive element and products' physical elements. In the 21c, where this process of integration is much more appreciated, it could be predicted that the competitiveness of a product relies not on technological aspect but on how close the product to a human being as a communication aid. In the world these days, the changes of lifestyle has been excelled due to the rapid growth of scientific technology. It is needed more than ever for the designers to participate in Human Sensibility Ergonomics to cope with the changes and to design products that are emotionally correct. Therefore, Human Sensibility Ergonomics and design should work closely, organizing a system to sharing the research outcomes and investing opportunities for numerous researchers to study.
