Supporting multi-user collaboration across diverse heterogeneous XR devices remains challenging in extended reality technology,primarily because of compatibility and interoperability issues. XR content creators are tasked with considering various input devices andplatforms across XR devices to facilitate user interactions. However, it is difficult to determine the practices for cross-platform designand XR content development. In this paper, we set up a cross-platform development environment based on OpenXR and XRdevelopment tools and develop XR collaboration content designed to support interactions across four different XR devices. Furthermore, this paper introduces XR content and discusses cross-platform development based on the Mixed Reality Toolkit. Theexperiment empirically demonstrates that users of diverse XR devices can interact with virtual objects and other users using variousinput methods such as gestures and touchscreens.

The purpose of this study is to examine how each type of consumer purchases them differently according to the existence of a bargain price and the range of differences between the fixed price and the reduced price in costly and inexpensive dress. There is an effect on the consumer's purhasing attitude according to the existence of a bargain price and the range of differences between the fixed price and the reduced price.
Effects of Mo on the Passive Films Formed on Ni-(15, 30)Cr-5Mo Alloys in pH 8.5 Buffer Solution
장희진,권혁상 한국전기화학회 2009 한국전기화학회지 Vol.12 No.3
The composition and semiconducting properties of the passive films formed on Ni- (15, 30)Cr-5Mo alloys in pH 8.5 buffer solution were examined. The depth concentration profile of passive films formed on Ni-(15, 30)Cr-5Mo in pH 8.5 buffer solution showed that Mo enhances the enrichment of Cr. The Mott-Schottky plot for the passive film on Ni-(15, 30)Cr- 5Mo closely resembled that for the film on Cr, whereas those for the less Cr-enriched film on Mo-free alloys showed similar behavior to that for the film on Ni. The acceptor density was reduced by increasing Cr content in Ni-(15, 30)Cr-(0, 5)Mo alloys, but addition of Mo considerably increased the acceptor density.

The common algae and industrial waste, chlorella and red mud, were co-pyrolyzed in carbon dioxide condition to fabricateiron-biochar composite. In order to investigate the direct effect of chlorella and red mud in the syngas generation and theproperty of biochar, experiments were performed using mixture samples of chlorella and red mud. The evolution offlammable gasses (H2, CH4, CO) was monitored during pyrolysis. The produced biochar composite was employed as acatalyst for persulfate activation for methylene blue removal. BET analysis indicated that the iron-biochar compositemainly possessed meso- and macropores. The XRD analysis revealed that hematite (Fe2O3) contained in red mud wastransformed to Fe3O4 during co-pyrolysis. The composite effectively activated persulfate and removed methylene blue. Among the composite samples, the composite fabricated from the mixture composed of 1:2 chlorella:red mud showed thebest performance in syngas generation and methylene blue removal.

In order to compare cytologic findings ol breast carcinoma in fine needle aspiration cytology (FANC) with histologic findings and prognostic factors including histologic grading, lymph node metastasis and stage, 79 cases of infiltrating ductal carcinoma diagnosed by FANC and confirmed by histology were analysed. We especially attempted to col relate nuclear grade, cellularity and smear pattern with histologic grade, type, status of lymph node metastasis and stage. The results are as fellows. 1. High nuclear grade was correlated with high histologic grade, lymph node metastasis and advanced stage. 2. Individual cell pattern was more frequently identified in high histologic grade and scirrhous or solid-tubular type than in low histolgic grade and papillotubular type. 3. Cellularity increased with higher histologic grade and lymph node metastsis. However cellularity was low in scirrhous type. 4. There is no relationship between nuclear grade and histologic type, between smear pattern and lymph node metastasis or stage, and between cellularity and stage. These results suggest that cytologic findings of breast carcinoma such as nuclear grade, cellularity and smear pattern are indicative of histologic findings in relation to histolgic grade and type. Especially, nuclear grade of FANC may yield valuable prognostic information.
