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.

This study recommends the evaluation measures and indicators to evaluate the operations and performance of each Foreign Research Information Centers (FRIC) established to support the effective and efficient use of the foreign academic journals at the national level. The indicators are comprised by 3 major sections, subdivided into 35 sub-indexes. Each of indicators is scored according to the weights derived from the AHP survey to the related researchers and the practitioners. As a result, total score of 1,000 is distributed to 3 major sections of operational strategy section (190), operational systems section (440), and operational outcomes (370). Based on the evaluation indicators, measure dictionary is developed, followed by preliminary tests both by the parent organization and by each centers, in order to check the feasibility of the measurement.

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.

The load distribution and deformation of rock-socketed drilled shafts subjected to axial loads are evaluated by a load-transfer method. The emphasis is on quantifying the effect of coupled soil resistance in rock-socketed drilled shafts using the 2D elasto-plastic finite element analysis. Slippage and shear load transfer behavior at the pile-soil interface are investigated by using a user-subroutine interface model (FRlC). It is shown that the coupled soil resistance provides the influence of pile toe settlement as the shaft resistance is increased to an ultimate limit state. The results show that the coupling effect is closely related to the value of pile diameter over rock mass modulus (D/$E_{mass}$) and the ratio of total shaft resistance against total applied load ($R_s$/Q). Through comparisons with field case studies, the 2D numerical analysis reseanably presented load transfer of pile and coupling effect due to the transfer of shaft shear loading, and thus represents a significant improvement in the prediction of load deflections of drilled shafts.

The frictional characteristics of galvanized sheet steels(GA, EG, EGF, EGN) for automobiles were studied and compared with that of cold rolled sheet steel. A draw bead tester which simulates metal flow through a draw bead in stamping die face was used to measure coefficients of friction of galvanized sheet steels for four kinds of lubricants. Stamping formability of galvanized sheet steels for quarter outer panel was examined. The results show that stamping formability and friction characteristics were mainly influenced by the nature of zinc coating, surface roughness and micro hardness of coated layer, and proved to be very sensitive to the lubricant used.

Properties of polymer based nanocomposites depend on dispersion state of embedded fillers. In order to examine the effect of dispersion state on rheological properties, a new bi-mode FENE dumbbell model was proposed. The FENE dumbbell model includes two separate ensemble sets of dumbbells with different fric­tion coefficients, which simulate behavior of well dispersed and aggregated carbon nanotubes (CNTs). A new parameter indicating dispersion state of the CNT was proposed to account for degree of dispersion quantitatively as well as qualitatively. Rheological material functions in elongational, steady shear, and oscillatory shear flows were obtained numerically. The CNT/epoxy nanocomposites with different dis­persion state were prepared depending on whether a solvent is used for the dispersion of CNTs or not. Dis­persion state of the CNT in the epoxy nanocomposites was morphologically characterized by the field emission scanning electronic microscope and the transmission electron microscope images. It was found that the numerical prediction was in a good agreement with experimental results especially for steady state shear flow.

Korea Institute of Science and Technology Information(KISTI) provides domestic researchers with science and technology information through NDSL Information Document Service(NIDS) network to improve research productivity in Korea. University libraries and information centers of research institutes are playing a major role in the NIDS collaboration network. In this study, we examined the relationship among the participating organizations for document delivery service using the social network analysis(SNA) method. Centrality of each organization in the NIDS network was analyzed with the indexes such as degree centrality, closeness centrality, betweenness centrality, and eigenvector centrality. The research results show that KISTI, KAIST, POSTECH, and FRIC are located at the center of the NIDS network. Based on the research results, this paper suggests several directions for improvement of document delivery service.

An analytical solution procedure is described to estimate the developed passive lateral earth Pressures behind a vertical rigid retaintng wall rotating about its toe into a mass of cohesionless soil. Various stases of wall rotation, starting from an at-rest state to an initial Passive state to a full Passive state, are considered in the analysis. Condition of failure defined by a modified Mohr-coulomb criterion, together with equilibrium conditions, is used to obtain the necessary equations for the solution. Using methods of stress characteristics and numerical finite difference, a complete solution within and on the boundaries of the entire solution domain is made possible. The variations of the soil shear strength and the wall friction at various depths and stages of wall rotation are also taken into account in the analysis. The results predicted by the developed method of analysis are compared with those obtained from the experimental model tests on loose and dense sand. The comparisons show good agreements at various stages of retaining wall rotation Fin- ally, results of analytical parametric study are presented to demonstrate the effects of wall fric- tion on the resultant thrust and distribution of developed lateral earth pressures.
