Research has taken priority of many activities in universities and it has eventually brought the heat on research support services of libraries to meet high expectation of university researchers. To identify the major content areas and service methods of research guides serviced through digital libraries of universities, this study investigated research guides of 60 university libraries in North America and Korea. As a result, 13 categories for research guide contents were identified and 5 crucial areas for the contents development were suggested. It also analyzed providing methods of online research guides and communicating methods between librarians and users. Librarians were identified as the prime human resource to develope and manage research guides, which will play an important role in expanding diversity of librarians' roles in the future.

The purpose of this study is to analyze the currently operating subject guides in academic libraries and to suggest measures for improvements of them. To do this, 22 out of 151 academic libraries which have more than 1,000 enrolled college students in the university and two institutes of science and technology were selected and the libraries were analyzed according to 12 criteria. The main results of the data analysis were as follows: First, the subject guides did not clearly indicate which service tool to use. Second, there was a difference in the subject guide format in the same academic library. Third, libraries tried to provide a lot of information sources on the subject guides without considering users' needs. By offering many kinds of information sources, students had to choose the information sources they needed. Improvement plans are: First, it is necessary to develop the subject guide of the college courses. Second, Content-based subject guides are necessary through standardized format. Third, it is necessary to unify the name of menu of information resource. Fourth, the number of information sources included in the subject guides should be minimized. Fifth, it is necessary to establish a cooperation system between academic libraries to develop the subject guides.

Researchers have been attending to the potential of curriculum materials as resources for professional development. In order for a curriculum material to fulfil such purpose, curriculum authors should intentionally attend to educativeness of the material. A feature of educative material is that its voice speaks to teachers. In this study, I explore educativeness of Algebra teacher guides by attending to their voice. In particular, I focused on the use of pronouns, modality, and imperatives. Findings indicate that some teacher guides have more educative voice than the others and that the amount each guide talk to teachers were less than sufficient. Implications for future research and practice are discussed.

The HANARO, a 30 MW multi-purpose research reactor in Korea, will be equipped with a neutron guide system, in order to transport cold neutrons from the neutron source to the neutron scattering instruments in the neutron guide hall near the reactor building. The neutron guide system of HANARO consists of the in-pile plug assembly with in-pile guides, the primary shutter with in-shutter guides, the neutron guides in the guide shielding room with dedicated secondary shutters, and the neutron guides connected to the instruments in the neutron guide hall. The functions of the in-pile plug assembly are to shield the reactor environment from a nuclear radiation and to support the neutron guides and maintain them precisely oriented. The primary shutter is a mechanical device to be installed just after the in-pile plug assembly, which stops neutron flux on demand. This paper describes the mechanical design of the in-pile plug assembly and the primary shutter for the neutron guide system at HANARO. The design of the guide shielding assembly for the primary shutter and the neutron guides is also presented.

When curing the composite restorations with light curing units, the light guides are often in direct contact with oral tissues, therefore contamination of light guides is inevitable. Curing light guides fall into the "semicritical" instrument category according to the Centers for Disease Control and Prevention (CDC) and must be heat or vapor-sterilized or at a minimum, these semicritical instruments must be sterilized in a liquid chemical agent. Currently, most common methods of maintaining sterility of the light guides are wiping the guide with a disinfectant, such as glutaraldehyde, after each patient use; using autoclavable guides; using presterilized, single-use plastic guides; and using translucent disposable barriers to cover the guide.

This study investigated the current state of online subject guides in Korean academic libraries and suggests improvement. Through the examination of 100 academic libraries' Web sites, only 14 online subject guides were identified, showing that the development of online subjects guides in Korea is still in infancy. The examined online subject guides were evaluated as high quality in terms of accessibility, integration of information resources, and format consistency, but low quality in the provision of specialized subjects, user instruction, and information retrieval systems. An online subject guide should be a one-stop service that provides fast access to information resources along with subject-specialized user instruction and effective communication with librarians.

Objectives: The surgical guide is a static computer-assisted device used for implant surgery planning and guidance. By taking an impression and referring to the patients' three-dimensional computed tomography scan of the desired implant site, a surgical guide can be created. During surgery, the surgical guide aids in achieving the designed implant placement position and direction. We examined and evaluated the long-term clinical outcomes of implant surgery using surgical guides. Materials and Methods: This study investigated a total of 15 patients with 32 implants that were placed using surgical guides from 2009 to 2011 with a mean follow-up period extended beyond 10 years. Patient demographics and implant survival rates were recorded. We analyzed marginal bone loss (MBL) by assessing the radiographs acquired at installation, three months after installation, and one month, one, two, and five years after prosthesis delivery. Results: The mean patient age was 57.33 years at implant placement. Of the 32 implants, five implants were placed in the anterior region and 27 implants were in the posterior region. Six implants failed and three of them were replaced, resulting in an 81.25% survival rate. The mean follow-up period was 10 years and nine months. Mean MBL compared to post-installation was significantly higher than at three months after installation, and one month, one, two, and five years after prosthesis delivery. Mean MBL at three months after installation, and one month, one year, and two years were significantly higher compared to the previous visit (P<0.05). However, MBL at five years after prosthesis delivery did not differ significantly compared to at two years. Conclusion: In this study, implant rehabilitation assisted by surgical guides exhibited favorable survival rates. With the limitation of the sample amount in this study, further research and more samples are required to evaluate the long-term clinical effectiveness of surgical guides.
