This study is to investigate and analyze the service quality and satisfaction perceived by users and librarians of the Foreign Research Information Center (FRIC). The survey results reveal that three groups of in-campus (internal) user group, external user group and interlibrary loan librarian group has highly perceived the service quality and satisfaction of the FRIC. Two user groups have statistically significant different perceptions on the service quality, loyalty, and satisfaction. Internal user group perceived more highly than external user group, in 6 items of satisfaction, 1 item of loyalty, and 7 items of service quality. Structural equation models of satisfaction and loyalty on two user groups were proved to be appropriate. Material factor including success rate of copied text and general physical status of the copy influences significantly on the user satisfaction in both groups.

Although academic library budgets have been decreasing, the rates of print and electronic journal subscription price have consistently increased. In response to this, as part of efforts to ensure access to foreign academic materials, the Ministry of Education and Korea Education & Research Information Service (KERIS) have initiated and operated Foreign Research Information Center (FRIC) since 2006, pursuing shared acquisition and sharing of foreign print journals. This study investigates the roles/values, issues raised by stakeholders, improvements in services, and new service elements of FRIC through the in-depth interviews with librarians in charge of FRIC in addition to examining its current state. The findings show that FRIC has contributed to sharing of academic materials and to promoting research. However, it was also found that the five types of stakeholders (i.e., the Ministry of Education/KERIS, universities/libraries, users, FRICs, and publishers/agencies) have diverse issues and problems with FRIC. Therefore, this study makes some suggestions to address the issues in terms of policy, system, management, and service.

Despite the rapid adoption of electronic journals, the need for print journals still remains. The current level of foreign journals acquisition poses a threat to strengthening the national research capabilities. Furthermore, there is too much overlap among academic libraries for foreign journals. We propose the establishment of government funded foreign research information centers to systematically acquire and distribute foreign print journals. We discuss specific approaches to selecting and operating such centers. Foreign research information centers are expected to enhance the national scholarly information infrastructure as well as the academic libraries' core capabilities.

This article analyzes the costs and benefits of the seven individuals centers of Foreign Research Information Center. Results of the investment feasibility analysis based on 30 years time span show that 0.99 of BCR (Benefit-Cost Ratio), 5.49% of IRR (Internal Rate of Return), and -507 million Won of NPV (Net Present Value). Sensibility analysis suggests that BCR can be influenced by the journal usage, social rate of discount, and elimination of the duplicate journal among individual centers.

The syndecan family consists of four transmembrane heparan sulfate proteoglycans present in most cell types and each syndecan shares a common structure containing a heparan sulfate modified extracellular domain, a single transmembrane domain and a C-terminal cytoplasmic domain. To get a better understanding of the mechanism and function of syndecan-4 which is one of the syndecan family, it is crucial to investigate its three-dimensional structure. Unfortunately, it is difficult to prepare the peptide because it is membrane-bound protein that transverses the lipid bilayer of the cell membrane. Here, we optimize the expression, purification, and characterization of transmembrane, cytoplasmic and short extracellular domains of syndecan4 (syndecan-4 eTC). Syndecan-4 eTC was successfully obtained with high purity and yield from the M9 medium. The structural information of syndecan-4 eTC was investigated by MALDI-TOF mass (MS) spectrometry, circular dichroism (CD) spectroscopy, and nuclear magnetic resonance (NMR) spectroscopy. It was confirmed that syndecan-4 eTC had an ${\alpha}$-helical multimeric structure like transmembrane domain of syndecan-4 (syndecan-4 TM) in membrane environments.

There have been little comprehensive research for studying impact of foreign journals on Korean scientists. The main reason for this is because there was no extensive citation index database of domestic journals for analysis. Korea Institute of Science and Technology Information (KISTI) built the Korea Science Citation Database (KSCD), and have provided Korea Science Citation Index (KSCI) and Korea Journal Citation Reports (KJCR) services. In this article, citing behavior of Korean scientists on foreign journals was examined by using KSCD that covers Korean core journals. This research covers (1) analysis of foreign document types cited, (2) analysis of citation counts of foreign journals by subject and the ratio of citing different disciplines, (3) analysis of language and country of foreign documents cited, (4) analysis of publishers of journals and whether or not journals are listed on global citation index services and (5) analysis for current situation of subscribing to foreign electronic journals in Korea. The results of this research would be useful for establishing strategies for licensing foreign electronic journals and for information services. From this research, immediacy citation rate (average 1.46%), peak-time (average 3.9 years) and half-life (average 8 years) of cited foreign journals were identified. It was also found that Korean scientistis tend to cite journals covered in SCI(E) or SCOPUS, and 90% of cited foreign journals have been licensed by institutions in Korea.

The need for network protection, accounting and resource management in foreign administrative domain requires appropriate security services. In this paper, we propose an access control protocol to support the authentication between mobile node and visiting subnet. Our hybrid way of approach aims to reduce computational overhead and minimize the use of network bandwidth. We also propose non-certificate based public-key cryptography to provide non-repudiation, which does not require CRL retrieval and certificate validation.

Rust is a promising system programming language that made its debut in 2010. It was developed to address the security problems in C/C++. It features a property called ownership, on which it relies to mitigate memory attacks. For this and its many other features, the language has consistently gained popularity and many companies have begun to seriously consider it for production uses. However, Rust also supports safe and unsafe regions under which the foreign function interface (FFI), used to port to other languages, falls. In the unsafety region, Rust surrenders most of its safety features, allowing programmers to perform operations without check. In this study, we analyze the security issues that arise due to Rust's safety/unsafety property, especially those introduced by Rust FFI.

High-quality and high-resolution meteorological information is essential to reduce damages due to disastrous weather phenomena such as flash flood, strong wind, and heat/cold waves. There are many meteorological observation stations operated by Korea Meteorological Administration (KMA) in Seoul Metropolitan Area (SMA). Nonetheless, they are still not enough to represent small-scale weather phenomena like convective storm cells due to its poor resolution, especially over urban areas with high-rise buildings and complex land use. In this study, feasibilities to use additional pre-existing networks (e.g., operated by local government and private company) are tested by investigating the effects of network density on the gridded horizontal distribution of two meteorological variables (temperature and precipitation). Two heat wave event days and two precipitation events are chosen, respectively. And the automatic weather station (AWS) networks operated by KMA, local-government, and SKTechX in Incheon area are used. It is found that as network density increases, correlation coefficients between the interpolated values with a horizontal resolution of 350 m and observed data also become large. The range of correlation coefficients with respect to the network density shows large in nighttime rather than in daytime for temperature. While, the range does not depend on the time of day, but on the precipitation type and horizontal distribution of convection cells. This study suggests that temperature and precipitation sensors should be added at points with large horizontal inhomogeneity of land use or topography to represent the horizontal features with a resolution higher than 350 m.

Cell-Free 시스템은 각 access point(AP)들이 고정적으로 특정 cell 내에 존재하는 유저(UE)에게 서비스하지 않고 서비스 지역 내에 넓게 분산 배치되어 있어 효율적으로 각 유저들에게 서비스할 수 있는 시스템이다. 그러므로 Cell-Free 시스템에서는 최적의 성능을 갖는 UE-AP association 을 찾는 것이 중요한 요소 중 하나로 여겨진다. 따라서 본 논문에서는 User-Centric 방식을 사용하는 Cell-Free MIMO 시스템에서 물리계층보안을 향상시키는 UE-AP association 기법을 제안한다.
