A self-compensated water-hydrostatic bearing is well known to have advantages in stiffness. In this paper, its concept is extended to a hydrostatic journal bearing for achieving higher stiffness. The finite element method is applied to analyze the load characteristics of the self-compensated hydrostatic journal bearing. The analysis results reveal that the self-compensated journal bearing has higher load capacity and higher stiffness than conventional, fixed capillary journal bearings. and that this benefit degrades in the case of high eccentricity. Thus, a spindle system with self-compensated journal bearings must be designed to ensure a sufficiently large load capacity. A rectangular type capillary is also introduced with consideration of the practical application of the self-compensated hydrostatic journal bearing. Theoretical analysis results show that the rectangular type capillary is more beneficial than conventional annular type capillaries in practical use. The experimental verification on the analysis method is made to show that the experimental results are in good agreement with theoretical results.

Libraries are encountering hostile conditions around journal licensing such as limited budget, the high price of packages, and vendor-led negotiation. They need to collect and analyze usage data of electronic journals to develop electronic journal collection appropriate for their own circumstances. The purpose of this study is to suggest an practical guideline for librarians' analysis of electronic journal usage statistics. For this, the study reviewed related previous studies and examined current state on usage statistics provided from COUNTER release 3 compliant vendors. Finally this study proposed five core statistics including full-text article request per journal, journal using rate, price per full-text article request, most use group, and low use group, and further discussed how to use them effectively for the electronic journal management.

In the circumstances of overflowing numbers of medical journals, progress of their own medical journal is one of the primary concerns of many medical societies. Among the 46-year-history of Journal of Korean Neurosurgical Society (JKNS), it undertook a period of important transition and preparation to take off for journal with international reputation during the period from 2001 to 2006. The overall process of manuscript handling, peer review, and editorial work has undergone systematic improvement. Workshops for authors, reviewer and editors were held, which were very helpful to improve the quality of submitted manuscript, peer review and editorial processing. Articles on the history, current status of the JKNS, citations and the change of proportion of types of articles were published, which provided insight about present condition and direction for further progress. It was changed into English journal in 2005. These efforts resulted in registration of the journal Chemical Abstract Service in 2005 and Science Citation Index Expanded in 2008 and SCOPUS in 2009. Now JKNS has become international journal, with about half of the submitted manuscripts from abroad, with increasing impact factor. Along with the effort of Korean Neurosurgical Society (KNS) members and support of KNS, dedication of Professor Dong Gyu Kim for the progress of JKNS is worth remembering, who served as Editor-in-Chief of JKNS during this period.

Objectives: The aim of this study was to evaluate the journal category "oral surgery" in Scopus and in the Science Citation Index Expanded (SCIE). Materials and Methods: The Journal of Oral and Maxillofacial Surgery (JOMS), The Journal of the Korean Association of Oral and Maxillofacial Surgeons (JKAOMS), and The Journal of Prosthodontic Research (JPR) were selected from the Scopus list of journals as oral surgery journals. Maxillofacial Plastic and Reconstructive Surgery (MPRS) was selected from PubMed as a Scopus oral surgery title. From these titles, 10 recently published articles were collected and used for reference analysis. Results: The percentage of citations from oral surgery journals was 26.7%, 24.5%, and 40.1% for JKAOMS, MPRS, and JOMS, respectively. In total, 1.1% of JPR's citations were from oral surgery journals and significantly fewer from other journals (P<0.001). The percentage of citations from dentistry journals excluding oral surgery journals was 11.9%, 34.4%, and 15.8% for JKAOMS, MPRS, and JOMS, respectively. For JPR, 80.6% of citations were from dentistry journals and significantly more were from other journals (P<0.001). Conclusion: Selected samples revealed that JPR is incorrectly classified as an oral surgery journal in Scopus. In addition, the scientific interaction among JKAOMS, MPRS, and JOMS was different to JPR in the reference analysis.

This paper describes the optimum design for journal bearings by using simulated annealing method. Simulated annealing algorithm is an optimization technique to calculate global and local optimum solutions. Dynamic characteristics of the journal bearing are calculated by using finite difference method (FDM), and these values are used for the procedure of journal bearing optimization. The objective is to minimize the resonance response (Q factor) of the simple rotor system supported by the journal bearings. Bearing clearance and length to diameter ratio are used as the design variables.

The herringbone groove journal bearing (HGJB) has chevron type grooves on stationary or rotating member of the bearing so that they pump the lubricant inward the grooves when journal rotates. As a result, the pressure is generated around the journal so that the radial stiffness and dynamic stability are improved comparing to the plain journal bearing (PJB) when the bearing operates near the concentric condition. The narrow groove theory, conventionally adopted to simulate the concentric operation of HGJB, is limited to the infinite number of grooves. A numerical study of air-lubricated HGJB is presented for the finite number of grooves. The compressible isothermal Reynolds equation is solved by using Finite Element Method together with the Newton-Raphson iterative procedure and perturbation method. The solutions render the static and dynamic performances of HGJB. Comparison of present results with a PJB validates previously published finite difference solution. The HGJB's geometric parameters influence its static and dynamic characteristics. The optimum geometric parameters are presented for the air-lubricated HGJB in particular conditions.

A new bearing concept, the wave journal bearing, has been developed to improve the steady and dynamic performance of a hydrodynamic journal bearing. This concept features a wave in inner bearing surface. Not only straight but also twisted wave journal bearing are investigated numerically. The performances of straight and twisted bearings are compared to a plain journal bearing over a relatively wide range of eccentricity. The bearing load and stability characteristics are dependent on the geometric parameters such as the number of waves, the amplitude and the starting point of the wave relative to the applied load. The wave journal bearing, especially for the twisted one, offers better stability than the plain journal bearing under all eccentricity and all wave to load orientation.
