As new technologies change a society, librarians need to understand and adapt to technology innovations. However, most innovations that librarians are supposed to adopt are government-driven or top-down changes; and there have been very few studies conducted to identify any patterns or consistencies in librarians' perceptions of innovation. This paper, therefore, has two research purposes. First, it introduces the Concern Based Adoption Model (CBAM) as one method to gain a deeper understanding of how librarians see such changes. Second, this study identifies school librarians' concerns regarding digital textbooks in South Korea applying the CBAM theory. The test signifies that school librarians present a typical non-user profile, and the pattern anticipates a potential resistance to digital textbooks. Also, it discovers the less experienced and innovator librarians had higher concerns across every stage. The findings underscore a need of various interventions. The CBAM theory suggests, in terms of intense Stage 0 and 1, it is required for school librarians to have events to gain information about digital textbook implementation. Regarding targeted interventions, since the biggest gaps occurs in Stage 4, Consequence and Stage 5, Collaboration, according to school librarians' experience and adoption style, new school librarians need stronger engagement with the community, which including associations, mentors or peer support, and collaborating with public libraries; innovator school librarians require opportunities to test and present their use of digital textbooks (Hall and Hord 1987).

The purpose of this study is to explore innovative adaptation of IT systems worldwide to support process-focus assessment. To this end, the study presents four cases from Australia, Singapore, the U.S.A., and Korea to inform educational policy and technology researchers and practitioners. Based on comparing the four chosen cases as benchmarks, the study concluded that IT systems and technologies can expedite and improve school interventions to enhance student learning in terms of time and quality. Also, educational big data and learning analytics can be used to systematically monitor and communicate individual student's progress among school stakeholders (i.e., teachers, students, parents, and administrators). Lastly, the study made some suggestions to support process-focused assessment in schools as following : 1) A more evidence-based, systems approach is needed to integrate the curriculum, instruction, and assessment to bridge the gap between educational policy and school practice; 2) It is critical to create ICT-friendly school environments so that meaningful data could be collected, analyzed, and stored from individual students and school units; 3) Teacher professional development is another area that needs special considerations and support to successfully implement process-focused assessment in schools.

In rough set literatures, methods for inducing minimal rules from a given decision table have been proposed. When the decision attribute is ordinal, inducing rules about upward and downward unions of decision classes is advantageous in the simplicity of obtained rules. However, because of independent applications of the rule induction method, inclusion relations among upward/downward unions in conclusion parts are not inherited to the condition parts of obtained rules. This non-inheritance may debase the quality of obtained rules. To ensure that inclusion relations among conclusions are inherited to conditions, we propose two rule induction approaches. The performances of the proposed approaches considering the inclusion relations between conclusions are examined by numerical experiments.

This is an interview with Professor Kwang-Hyung Lee, founding Dean of KAIST Moon Soul Graduates School of Future Strategy and founder of the Department of Bio and Brain Engineering of the same university casting two questions about academics. The first question is what pattern is desirable in the evolution of research topics of an academics. While traditional researchers in science and engineering tend to focus on one subject in ever greater depth over time, Professor Lee's research agenda has spanned several new topics by gradually changing the content of the study: from artificial intelligence to bio and brain research, and to creativity development method, further to future study. The second question is about researchers' social responsibility. He has devoted to contributes to industry fields and the nation through academic activities as well as educating several successful business people, founding a new academic department and graduate school of future studies.

Abortive infection systems (Abi) are phage resistance systems that can be prophage-encoded. Here, two genes encoding an Abi system were identified on a prophage sequence contained by the chromosome of the Levilactobacillus brevis strain UCCLBBS124. This Abi system is similar to the two-component AbiL system encoded by Lactococcus lactis biovar. diacetylactis LD10-1. The UCCLBBS124 prophage-derived Abi system (designated here as AbiL₁₂₄) was shown to exhibit specific activity against phages infecting L. brevis and L. lactis strains. Expression of the AbiL₁₂₄ system was shown to cause reduction in the efficiency of plaquing and cell lysis delay for phages of both species.

This paper aims to present a polynomial approach to the steady-state optimal filtering for delayed systems. The design of the steady-state filter involves solving one polynomial equation and one spectral factorization. The key problem in this paper is the derivation of spectral factorization for systems with delayed measurement, which is more difficult than the standard systems without delays. To get the spectral factorization, we apply the reorganized innovation approach. The calculation of spectral factorization comes down to two Riccati equations with the same dimension as the original systems.

The purpose of this paper is to evaluate of The University of Science and Technology (UST) as field-oriented graduate school model. The UST is unique in world-wide because of its operating system through the synergy effect of research and education and its interdisciplinary major system differentiated from the traditional graduate school, It first deals with measuring the users satisfaction by using a five-point Likert scale to analyze the general and special factors of UST, through which some findings are pointed out as follows; the education aims and visions are highly satisfied while essential factors in field-oriented education such as curriculum composition, apprentice and tailored education system, field training are not so high level. Finally it points out some suggestions for the UST development.

Technological innovation generates products, services, and processes that can disrupt existing industries and lead to the emergence of new fields. Distributed ledger technology, or blockchain, offers novel transparency, security, and anonymity characteristics in transaction data that may disrupt existing industries. However, research attention has largely examined its application to finance. Less is known of any broader applications, particularly in Industry 4.0. This study investigates academic research publications on blockchain and predicts emerging industries using academia-industry dynamics. This study adopts latent Dirichlet allocation and dynamic topic models to analyze large text data with a high capacity for dimensionality reduction. Prior studies confirm that research contributes to technological innovation through spillover, including products, processes, and services. This study predicts emerging industries that will likely incorporate blockchain technology using insights from the knowledge structure of publications.
