Recently, services using metaverse in various fields are increasing, the technology is behind the metaverse is rapidly developing. Consequently, it is necessary to provide metaverse services in university libraries. Therefore, this study examined the status of using metaverse in domestic university libraries and the librarians response to it. To this end, the cases of foreign libraries and domestic university libraries were analyzed. Furthermore, an interview was conducted with nine librarians of the university library, who has running metaverse service, to collect data on the current status of the university library metaverse and perceptions of it to identify difficulties and requirements of running the service. Based on the results, it is proposing to get the differentiation of metaverse service, acquire professionals, activate education, expand the browsing feature, and select proper platforms as a way to vitalize the metaverse of domestic university libraries. It is expected that this study will help to running or planning the metaverse service of the university library. 최근 다양한 분야에서 메타버스를 활용한 서비스가 증가하고 있으며 이에 따라 기술이 급속도로 발전하고 있다. 이러한 배경에서 대학도서관에서도 시대의 흐름에 따라 메타버스 서비스를 제공할 필요가 있다. 따라서 본 연구는 국내 대학도서관의 메타버스 활용 현황과 사서의 인식을 알아보기 위해 수행되었다. 이를 위해 국외 도서관의 메타버스 사례와 국내 대학도서관의 메타버스 사례를 분석하였다. 또한, 메타버스 운영 경험이 있는 대학도서관 사서 9명을 대상으로 면담을 통해 대학도서관의 메타버스 활용 현황과 인식에 대한 자료를 수집하여 메타버스의 운영에서 겪었던 어려움, 요구사항 등을 파악하였다. 연구결과를 토대로 국내 대학도서관의 메타버스 활성화 방안으로 메타버스 서비스의 차별화, 전문인력의 확보, 교육의 활성화, 자료 열람 기능의 확대, 서비스에 따른 플랫폼 선택을 제안하였다. 본 연구를 통해 대학도서관에서 메타버스를 운영하거나 계획할 때 있어 도움을 줄 것으로 기대한다.

Purpose: To evaluate a simplified method to measure peripapillary choroidal thickness using commercially available, three-dimensional optical coherence tomography (3D-OCT). Methods: 3D-OCT images of normal eyes were consecutively obtained from the 3D-OCT database of Korea University Medical Center On the peripapillary images for retinal nerve fiber layer (RNFL) analysis,choroidal thickness was measured by adjusting the segmentation line for the retinal pigment epithelium to the chorioscleral junction using the modification tool built into the 3D-OCT image viewer program. Variations of choroidal thickness at 12 sectors of the peripapillary area were evaluated. Results: We were able to measure the peripapillary choroidal thickness in 40 eyes of our 40 participants, who had a mean age of 41.2 years (range, 15 to 84 years). Choroidal thickness measurements had strong interobserver correlation at each sector (r = 0.901 to 0.991, p < 0.001). The mean choroidal thickness was 191 ±62 μm. Choroidal thickness was greatest at the temporal quadrant (mean ± SD, 210 ± 78 μm), followed by the superior (202 ± 66 μm), nasal (187 ± 64 μm), and inferior quadrants (152 ± 59 μm). Conclusions: The measurement of choroidal thickness on peripapillary circle scan images for RNFL analysis using the 3D-OCT viewing program was highly reliable and efficient.

Purpose: To compare retinal layer thickness and chorioretinal vascular density (VD) between acute and chronicbranch retinal vein occlusion (BRVO). Methods: This study included patients with BRVO. The VD of the superficial capillary plexus (VDs), the VD ofthe deep capillary plexus (VDd), and VD of the choriocapillaris were obtained using optical coherence tomographyangiography. Acute and chronic BRVO data were compared to assess differences between the involvedand uninvolved areas. Results: We included 17 eyes with acute BRVO and 23 eyes with chronic BRVO. The VDs in the involved areawere not significantly different between the involved area and in the uninvolved area in acute BRVO (p = 0.551). However, the difference was significant in chronic BRVO (p = 0.013). The VDd in the involved area was lowerthan in the uninvolved area in both acute and chronic BRVO (p = 0.020, p = 0.003, respectively). In addition,the VD of the choriocapillaris values did not differ significantly between acute and chronic BRVO, or betweeninvolved and uninvolved areas. The VDs in the involved area in chronic BRVO were lower than in acute BRVO(p = 0.047), and the VDd did not differ between acute and chronic BRVO in all areas. Conclusions: Vascular impaired patterns in the retinal layer differed between acute and chronic BRVO. Theseresults may suggest that vascular change and remodeling develops differently in acute and chronic phases inBRVO.

Purpose: To determine the effect of photodynamic therapy (PDT) on patients with chronic central serous chorioretinopahty (CSC). Methods: This was a retrospective multicenter study. We collected demographic and ophthalmic data for patients with chronic CSC who were treated with PDT from 16 institutions in Korea. The best corrected visual acuity (BCVA), ophthalmoscopic finding and optical coherence tomography at baseline and follow-up visits were compared longitudinally. Results: Sixty-five eyes of 65 patients were recruited. Males (51 patients, 78.5%) outnumbered females (14 patients, 21.5%). The mean age was 46.4±10.0 years of age (28~69). By 1 month, mean BCVA improved from 0.47 to 0.37 (logarithm of the minimum angle of resolution) (P <0.01). This BCVA increased throughout 6 months. Subretinal fluid resolved partially or completely in 89.1% of the patients. Central macular thickness (CMT) decreased from 303.4 to 168.7 μm. The amount of change in CMT after PDT was correlated to the female sex and prePDT CMT. At 3 months after PDT, the amount of change in BCVA was significantly related to that of change of CMT (p <0.05). Adverse events were reported in 4 cases, however, most were mild. Conclusions: PDT was effective and safe for treating chronic CSC.
