The role of knowledge as the key source of potential advantage for organizations and economies has become a hotly debated topic. Some studies found that organizations had their own knowledge management styles. Knowledge Management draws form existing resources that organizations may already have in place. Checking the organization's infrastructures for Knowledge Management is the first step for Knowledge Management. Although the as- is analysis of organizations before knowledge management is important, but there is no study on the readiness for Knowledge Management. This study reports on the development of an instrument designed to measure the readiness of an organization for knowledge Management. Starting with the literature, 4 dimensions - strategy, process, culture/people, and technology - and 18 factors were identified. Then, a questionnaire for measuring readiness was created. Finally, the instrument was pilot tested to prove its reliability and validity. Following the pilot test, the factors all demonstrated acceptable levels of reliability. The result is 19 factors instrument comprising 4 dimensions which provide a useful tool for measuring the readiness for Knowledge Management.

During the industrial plant system life cycle, required technologies are developed and assessed to analyze their performance, risks and costs. The assessment is called technology readiness assessment (TRA) and the measure of readiness is called technology readiness level (TRL). The TRL consists of 9 levels and through the TRL assessment, the technology to be developed and its components are assigned to their appropriate TRL. TRL assessment should be performed in each life cycle stages to monitor the technology readiness and analyze the potential risks and costs. However, even though the concept of TRL has been largely adopted by numerous organizations and industry, direct and clear assignment of target TRL for each life cycle stage has been overlooked. Direct mapping/assignment of target TRL for each life cycle has benefits as follow: (1) the technical risks condition of each life cycle stage can be better understood, (2) cost incurred if the technology development is failed can be analyzed in each life cycle stage, and (3) more effective decision making because the technology readiness achievement for each life cycle stages is agreed beforehand. In this paper, we propose a steel-making plant system life cycle and TRL assignment to each of the system life cycle stage. By directly assigning target TRL for each life cycle stages, we look forward to a more coordinated (in terms of exit criteria) and highly effective (in terms of technical risks identification and eventually prevent project failure) technology development and assessment processes.

The research purpose of this paper is to empirically examine the effects of technological readiness and innovation on logistics performance. To build up and maintain an important role in global supply chains, nowadays it is obvious that countries and logistics providers need to achieve competitive advantage in terms of digitalization. However, there is a lack of empirical studies about the impacts of information technologies and innovation potential on the logistics efficiency of countries. Hence, the study analyzes whether the corresponding pillars of the Global Competitiveness Index (GCI) matter for the Logistics Performance Index (LPI) and its dimensions. For determining the effects, the pooled regression approach is applied. The results show that technological readiness and innovation are positively and statistically significantly correlated with logistics performance: competence and quality of logistics services, efficiency of customs clearance processes, ability to track and trace consignments, frequency with which shipments reach consignee within scheduled or expected time, and ease of arranging competitively priced shipments. The findings of this study suggest that investments in innovations and technology progress improve countries' logistics efficiency, which is an important prerequisite for enabling Logistics 4.0 and thus, Industry 4.0 and the digital transformation of the economy and society.

본 논문에서는 시각에 대해 반응하는 운동 행동의 효과를 분석하기 위해서 응답속도정합-유발전위(RTA-ERP: Response Time Aligned-Event Related Potential)를 모델링하고, RTA-ERP의 진폭과 응답 속도를 이용하여 사이먼 효과를 분석하였다. 건강한 성인 15명(남성 9명, 여성 6명, 평균 연령 31세)을 대상으로, 같은 숫자에 대한 다른 숫자를 찾아 반응하는 '양자극방안' 실험을 7분 동안 수행하였다. 실험결과 제안된 RTA-ERP는 기존의 ERP에 비해 뇌에서의 처리시간 차이에 따른 변이를 보상할 수 있었으며, 향상된 LRP(Lateralized Readiness Potential)와 Pe(Error Related Positivity)를 나타내었다. '일치', '불일치' 시험 패턴에 대하여 '일치'에 대한 RTA-ERP의 진폭과 응답속도는 각각 '불일치'보다 컸으며 진폭은 $0.03{\mu}V$ 크고 반응속도는 43 ms 만큼 빨랐다. 응답속도에 따른 동기 시점을 보정하여 정합함에 따라, RTA-ERP의 진폭특성은 사이먼 효과의 특징인 ERP의 P300 진폭과 대응함을 확인하였다.

본 논문에서는 Electrocorticogram(ECoG) 신호를 이용하여 손과 팔꿈치의 움직임을 추론하는 방법을 제안한다. 환자로부터 다수의 채널을 이용하여 표면 근전도 신호와 ECoG 신호를 동시에 취득하였다. 추론하는 동작은 손을 쥐었다 펴는 동작과 팔꿈치를 안으로 굽히는 동작이며, 외부 자극에 의해 동작을 수행하는 방법 대신 환자의 자유의지에 의해 동작을 수행하게 하였다. 표면 근전도 신호를 이용하여 동작을 수행한 운동 시점을 찾고, ECoG 신호를 이용하여 동작을 추론한다. 각 동작의 특징을 추출하기 위하여 ECoG 신호를 전체 대역을 포함한 ${\delta}$, ${\Theta}$, ${\alpha}$, ${\beta}$, ${\gamma}$ 총 6개의 대역을 나누어 정보 엔트로피를 구하고, 최대우도추정법을 사용하여 동작을 추정하였다. 실험 결과 감마대역의 ECoG를 사용할 경우 다른 대역을 사용할 때 보다 높은 평균 74%의 성능을 보이며, 다른 대역보다 감마 대역에서 높은 추정 성공률을 보였다. 또한 운동 시점을 기준으로 3개의 시간 구간으로 나누어 준비전위를 포함하는 'before' 구간과 'onset' 구간을 비교하였다. 'before' 구간과 'onset' 구간에서 추정 성공률은 각각 66%, 65%로 준비전위를 이용할 수 있다는 것을 알 수 있었다.

Decarbonization and energy transition can be considered as a main concern even for the oil industry. One of the initiatives to reduce emissions under studies considers the use of renewable energy as a complimentary supply of electric energy of the production platforms. Wind energy has a higher TRL (Technology Readiness Level) than other types of energy converters and has been considered in these studies. However, other types of renewable energy have potential to be used and hybrid concepts considering wind platforms can help to push the technological development of other types of energy converters and improve their efficiency. In this article, a preliminary hydrodynamic assessment of a new concept of hybrid wind and wave energy conversion platform was performed, in order to evaluate the potential of wave power extraction. A multiple OWCs (Oscillating Water Column) WEC (Wave Energy Converter) design was adopted for the analysis and some simplifications were adopted to permit using a frequency domain approach to evaluate the mean wave power estimation for the location. Other strategies were used in the OWC design to create resonance in the sea energy range to try to maximize the potential power to be extracted, with good results.

Objectives: This paper describes the concept, principles, and strategies and directions for community participation in health promotion. Methods: Descriptions of and discussions on community participation in this paper are based on the results of selected peer-reviewed research articles, white papers, and practice manuals which address the issues of community participation and community empowerment, and principles and strategies for practice in community health promotion. Results: In ladder-of-community-participation models, the level of participation ranges from non-participation to the stages where communities have partnerships, delegated power, and control. Enhancement of participation is presented as a continuum of informing - consulting - involving - collaborating - empowering. For community participation to reach its fullest potential, the types and levels of participation desired should be clearly decided at the beginning. Along with community readiness for participation, public health system should also be in place readily to process community participation for health promotion with appropriate procedures, guidelines, methods, resources, and stakeholders' commitment and support. Conclusions: For the promotion of participation in community health, readiness for participation of both community and public health system should be prepared.

The purpose of this study is to evaluate the future potential value of CTE(Critical Technology Element)s that are evaluated to be low in TRA(Technology Readiness Assesment) and to present investment prioritization technologies in defense R&D(Research and Development) based on them. To do this, we used the DEA(Data Envelopment Analysis) method, which is useful in evaluating the efficiency of the organization. Specifically, we suggest a systematic framework to evaluate the future value of CTEs by setting the CTEs derived from the TRA process to DMU(Decision Making Unit)s, the cost and time required to develop each CTE as the input factor of the DEA and the effects of the development of each CTE as the output factor of the DEA respectively. We also conducted an illustrative case study on radar technologies to demonstrate the usefulness of the proposed approach.

The article considers the fundamentalization of education in improving the future specialists professional training with usage of multimedia technologies by various scientists. Various points of view and approaches to defining the concepts of fundamentalization of education and multimedia technologies are identified. The concept of fundamentalization of professional training of a future specialist is based on the goals and functions of fundamentalization and - on the ways and means of achieving it, etc. Most authors agree only in their views that the fundamentalization of education is aimed at improving the quality of education and the education of the individual. Others involve the formation of a culture and worldview, increasing the creative and intellectual potential, forming the professional competence of a specialist and the potential for further education, and so on. The term multimedia refers to interactive systems that provide processing of moving and still video images, animated graphics, high-quality audio and speech. It is found out that professional training of a specialist by means of multimedia technologies includes not only the activities of the teacher and student, which form the learning process, but also the independent activity of the subject, self-development, assimilation of experience by the subject through analysis, comprehension and transformation of the field of activity in which he is included. It is revealed through the implementation of which approaches to the fundamentalization of higher professional education, it becomes possible to fully present theoretical training courses and effectively pass practical training by students, which contributes to improving the quality of training of future specialists in higher education institutions. Theoretical analysis of scientific views indicates a fairly serious attention of scientists to the problem of professional readiness of specialists and the possibility of higher educational institutions in preparing for it. At the same time, professional readiness is considered from different positions: as an active state of a person, which manifests itself in activity; as a result of activity; as goals of activity; as a quality that characterizes the attitude to solving professional problems and social situations; as a prerequisite for purposeful activity; as a form of activity of the subject; as an integral formation of personality; as a component of socio-professional culture; as a complex professionally significant neoplasm of the individual.
