It has become the heavy burden for many domestic colleges to renew the e-journal paywall licenses because major publishers keep raising license fees to access the new articles in Korea. In order to overcome these costly expenditure, the universities in US and the several governments in EU attempted the new models of open access option in the form of pilot contract with major publishers. Unlikely, there is no active discussion regarding open access options among domestic scientists, which may limit the generation of creative models in Korea. In this paper, the cases of US and EU negotiations with the Elsevier publisher were introduced and also evaluated in a qualitative manner whether any combined models could be applicable to future consideration.

To understand the characteristics of open access journals in Korea, this research examined the 1,438 KCI journals in the fields of humanities, social sciences, natural sciences, engineering, medicine, agriculture & oceanography, art & sports, and interdisciplinary. 21% of the KCI journals are freely available at the publisher's websites or open access DBs(OA). 34% are available only in the commercial fulltext DBs(TA) and 34% combined TA and OA. 48% of the OA journals can be found on the free fulltext DBs and 52% are accessed on the publisher's websites. OA journals in humanities and social science are available mainly on the publisher's websites. As compare with this, OA journals of STM fields are available via the free fulltext DBs. Medicine(30%) and social sciences(25%) have the highest overall share of OA. There are field differences in the rate of OA journals. In the fields of social sciences and humanities, 15% of the journal are open access. In case of medicine field, 60% are open access journals. OA journals in natural science and engineering are each 33% and 24%.

The purpose of this study was to analyze STEAM elements and convergence types that appeared in the creative and convergent activities in elementary school science textbooks, which were converted from the national issuance system to the authorized system in 2022. For this study, 6 elementary school science textbooks for 3rd and 4th graders were selected. And STEAM elements in creative and convergent activities were analyzed by publishers, grade-semesters, and science fields, and the convergence type was analyzed for each publisher. The results of this study are as follows. First, the total frequencies of STEAM elements and the ratios of each element in the creative and convergent activities of textbooks were different for each publisher. However, among the four elements except for science (S) element in all publishers, the tendency to have a high proportion of art (A) element and a very low proportion of mathematics (M) element was common. Second, the higher the number of fused STEAM elements, the lower the rate of appearance in the textbooks in overall. Also the ratio of convergence types of STEAM elements varied by each publisher. Third, the ratio deviations of art (A), technology (T), and engineering (E) elements for each grade-semester were not large, but the ratio deviation of the mathematics (M) element was large. Fourth, technology (T) and engineering (E) elements appeared a lot in the fields of 'movement and energy' and 'material', while art (A) element appeared a lot in the fields of 'earth and universe', 'life', and 'integration'.

The software components of embedded control systems get extremely complex as they are designed into distributed systems get extremely complex as they are designed into distributed systems consisting of a large number of inexpensive microcontrollers interconnected by low-bandwidth real-time networks such as the controller area network (CAN). While recently emerging middleware technologies such as CORBA and DCOM address the complexity of distributed programming, they cannot be directly applied to distributed control system design due to their excessive resource demand and inadequate communication models. In this paper, we propose a CORBA-based middleware design for CAN-based distributed embedded control systems. Our design goal is to minimize its resource need and make it support group communication without losing the IDL (interface definition language) level compliance to the OMG standards. To achieve this, we develop a transport protocol on the CAN and a group communication scheme based on the well-known publisher/subscriber model. The protocol effectively realizes subject-based addressing and supports anonymous publisher/subscriber communication. We also customize the method invocation and message passing protocol, referred to as the general inter-ORB protocol (GIOP), of CORBA so that CORBA method invocations are efficiently serviced on a low-bandwidth network such as the CAN. This customization includes packed data encoding and variable-length integer encoding for compact representation of IDL data types. We have implemented our CORBA-based middleware on the mArx real-time operating system we have developed at Seoul National University. Our experiments clearly demonstrate that it is feasible to use CORBA in developing distributed embedded control systems possessing severe resource limitations. Our design clearly demonstrates that it is feasible to use a CORBA-based middleware in developing distributed embedded systems on real-time networks possessing severe resource limitations.

The purpose of this study was to examine the differences among journal publishers and among academic disciplines on factors influencing the adoption of open access. Through the analysis of previous studies, we identified five such factors: journal publishers' attitudes, ability, confidence, social influence and material resources available for open access. The results show that a significant difference among journal publishers from social influence factor. This result implies that efforts toward journal subscribers to have a positive attitude and material resources are important factors for journal publishers. There was a significant difference among academic disciplines in terms of journal publishers' attitudes and ability factors. The findings of this result imply that academic journals need to share more information about open access and that priority should be given to journals that have the ability to influence the adoption of open access.

This study was conducted to examine Sci-Hub, which provides the original text of academic papers to be provided for a fee by bypassing copyright, and to establish a basic basis for understanding the usage behavior of researchers with access restriction in Korea by analyzing the domestic Sci-Hub usage based on the dataset released by Sci-Hub in 2017. Therefore, after grasping the current status of the world related to Sci-Hub, the categories were set and analyzed by region where the dataset was downloaded, subject matter of academic papers, publisher, OA status, and published year. As a result of the study, the most downloaded areas were Seoul and the metropolitan area, and papers and journals in the field of natural science were downloaded the most, and about 20% of papers were in Open Access state. The papers published between 2010 and 2017 were the most downloaded, and IEEE's papers were the most downloaded, showing that recently published academic papers in the natural sciences were the most downloaded by the time they were downloaded.

The title page of a book is a reliable source, since it. together with its verso, usually contains all bibliographically significant data. Generally, the title page is a page at the beginning of a book giving its title and the names of the author and publisher. Prescribing a source of information from which data elements should be derived is a way of specifying how an entity can represent itself. In simpler times, when bibliographic entities were fur the most part books published in Western countries, the choice of source was obviously the title page. the "face of the book".

IPCS(Inter Process Communication Service) is a real-time communication middleware designed for warship combat battle systems based on publisher-subscriber communication model. Because IPCS was originally designed to operated under 100 Mbps network environment, increasing network speed into Gigabit environment does not linearly increase the throughput of IPCS. To solve this problem, we anaylized IPCS structure and optimized IPCS into Gigabit-Ethernet environment. We found parameters to improve IPCS based on UDP and Token-ring structure. By improving, IPCS has reliability and higher throughput than TCP although IPCS is based on UDP.
