This study proposes a new method for developing gesture vocabularies for mixed reality (MR) environments by reducing legacy bias. A comparative experiment was conducted using picture scene priming and virtual scene priming methods to verify the effectiveness of task scene presentation using MR technology for priming. The results showed that VSP reduced biased gestures and improved the usability and semantic agreement of the resulting gesture vocabulary. The study suggests that VSP is a more effective gesture elicitation method for MR environments.
고객여정지도를 활용한 VR 쇼핑 플랫폼 맨손 제스처 어휘 개발
차오셴웨(Xian Yue Qiao),김세화(Se-Hwa Kim) 한국콘텐츠학회 2022 한국콘텐츠학회논문지 Vol.22 No.11
VR 쇼핑환경에서 맨손 제스처 인터랙션은 디바이스를 이용한 인터랙션 방식보다 사용자 몰입이 용이하다. 맨손 제스처 동작과 인터랙션의 의미를 맵핑하는 ‘맨손 제스처 어휘’ 개발은 주로 Wobbrock 등(2005)이 개발한 ‘추측성 연구(Guessability study)’ 과정에 따라 진행된다. 그런데 이 과정에서 연구자가 과업을 정의하기 때문에 사용자의 수요를 반영하기 어렵다는 문제가 있다. 이를 개선하기 위하여, 별도의 과업 정의 단계를 추측성 연구 방법에 추가하고자 하였다. 현장 관찰을 기반으로 고객여정지도(CJM)를 제작하여 쇼핑 사용자들이 필요로 하는 과업들을 정의하고, 정의된 과업을 기준으로 제스처 어휘 개발과정을 진행하여 사용자가 필요에 따른 제스처 어휘들을 도출하고자 하였다. 먼저, 사용자 관찰과 고객여정지도를 통해 쇼핑 활동에서 필요로 하는 12가지 과업을 도출하였다. 다음으로, 12명의 참여자의 아이디어를 기반으로 295개 제스처를 수집하고, 일치율을 계산해서, 12개의 제스처 어휘를 도출하였다. 마지막으로, 도출된 제스처들에 대한 사용성 평가에서 기억 가능성, 직관성, 적합성이 평균 이상으로, VR 쇼핑 플랫폼의 과업 수행에 적합한 제스처 어휘들이 도출되었다고 판단할 수 있었다. Freehand gesture interaction is easier for users to immerse in than the interaction method using a device in the VR shopping environment. The development of ‘freehand gesture vocabulary’, which matches the meaning of freehand gestures and interactions, is mainly conducted according to the ‘Guessability study’ process developed by Wobbrock et al. (2005). However, this process does not adequately address the needs of the user as the researcher defines the task. To improve it, it was necessary to add a task definition step to the guessability study. Using field observation and Customer Journey Map (CJM), the tasks required by shopping users were defined, and the gesture vocabulary development process was carried out with the defined tasks to derive gesture vocabularies. First, 12 tasks required for shopping activities were derived through user observation and CJM. And then, 295 gestures were collected from the ideas of 12 participants, the agreement rate was calculated, and 12 gesture vocabularies were derived. Finally, in the usability evaluation, it could be determined that the memorability, intuition, and suitability were above average, and gesture vocabularies suitable for the task performance of the VR shopping platform were derived.

Qiao Liang,Jie Liu,Jun Wang,Xian-Tao Zeng,Shuo-Guo Wu 대한토목학회 2022 KSCE JOURNAL OF CIVIL ENGINEERING Vol.26 No.2
Based on the theory of limit and the unified strength theory, the three-dimensional failure pattern and the corresponding velocity field on the heading face for cyclical footage are proposed, considering the influence of the cyclical footage and the intermediate principle stress on the heading face stability. Addition, the influence of various parameters on the heading face stability is analyzed. The present study shows that the first increase in internal friction angle (lower than 25°) can promote the heading face stability. Then, the increase in the cohesion can promote the stability when the internal friction angle is higher than 25°. In addition, for the relatively intact instead of the poor surrounding rock, the promotion of the stress conditions of the heading face, caused by by the intermediate principle stress, indicates that the Mohr-Coulomb criterion is conservative.

Jingping Xian,Cuiyue Dong,Lifang Qiao 보안공학연구지원센터 2016 International Journal of Smart Home Vol.10 No.2
Leisure agriculture is an industry which combines the agricultural production and leisure recreation. In order to promote the development of leisure agriculture, it is particularly important to conduct an analysis of its development from the overall perspective of the city. This paper takes Xinxiang City of Henan Province in China as an example and adopts GAHP-SWOT as the analysis method. Based on affirming the influencing factors of advantages, disadvantages, opportunities and threats, the AHP method is adopted to calculate the weights of different factors and sort them so as to realize the organic combination of the qualitative and quantitative analysis. Group Decision is used in computation to exert the collective intelligence. The result shows that the indicators S4 and S3 are relatively high-weight advantages while the indicators W1 and W4 are relatively high-weight disadvantages, and the indicators O4 and O2 are relatively high-weight opportunities while the indicators T5 and T2 are relatively high-weight threats. The development strategy was put forward according to the analysis result in order to provide decision-making basis for the development planning of leisure agriculture in Xinxiang City.

( Jie Wu ),( Xian Qiao Zeng ),( Hong Bin Zhang ),( Han Zhong Ni ),( Lei Pei ),( Li Rong Zou ),( Li Jun Liang ),( Xin Zhang ),( Jin Yan Lin ),( Chang Wen Ke ) 한국미생물 · 생명공학회 2014 Journal of microbiology and biotechnology Vol.24 No.5
The highly pathogenic avian influenza A (HPAI) viruses of the H5N1 subtype infect poultry and have also been spreading to humans. Although new antiviral drugs and vaccinations can be effective, rapid detection would be more efficient to control the outbreak of infections. In this study, a phage-display library was applied to select antibody fragments for HPAI strain A/Hubei/1/2010. As a result, three clones were selected and sequenced. A hemagglutinin inhibition assay of the three scFvs revealed that none exhibited hemagglutination inhibition activity towards the H5N1 virus, yet they showed a higher binding affinity for several HPAI H5N1 strains compared with other influenza viruses. An ELISA confirmed that the HA protein was the target of the scFvs, and the results of a protein structure simulation showed that all the selected scFvs bound to the HA2 subunit of the HA protein. In conclusion, the three selected scFVs could be useful for developing a specific detection tool for the surveillance of HPAI epidemic strains.

In the present work, tin incorporated MCM-48 catalysts were prepared by different strategies andapplied in the synthesis of MB-AC and MBOH. The performance of the catalysts is strongly affected bymesochannel environment and acid texture. The organic-graft method (Sn-G-MCM-48) can modify themesochannel environment and enhance the acid intensity and concentration (0.28 mmol/gcat),resulting in the improvement of the catalytic activity to the target reactions. The total yield of MB-AC andMBOH is as much as 68.4% over Sn-G-MCM-48 under mild conditions.

Two genes coding for eukaryotic translation initiation factors, eIF4E.a and eIF4E.c, were isolated from twelve accessions of Chinese cabbage (Brassica rapa L. ssp. pekinensis). Polymorphism analysis revealed that 94and 142 polymorphic sites were characterized from allele of BraeIF4E.a and BraeIF4E.c which produced complex haplotype structures. Six novel haplotypes were characterized from the two alleles respectively. Among the six novel haplotypes of BraeIF4E.a, three loss-of-function mutations were identified in which a conserved single nucleotide deletion mutation cause the early termination of BraeIF4E.a coding product; while for six new BraeIF4E.c haplotypes, their coding product show amino acid substitution mutations on non-conservative amino acid residues which might affect TuMV infection in Chinese cabbage.
Effective Coupling of a Topological Corner-state Nanocavity to Various Plasmon Nanoantennas
Na Ma,Ping Jiang,You Tao Zeng,Xiao Zhen Qiao,Xian Feng Xu 한국광학회 2022 Current Optics and Photonics Vol.6 No.5
Topological photonic nanocavities are considered to possess outstanding optical performance, and provide new platforms for realizing strong interaction between light and matter, due to their robustness to impurities and defects. Here hybrid plasmonic topological photonic nanocavities are proposed, by embedding various plasmon nanoantennas such as gold nanospheres, cylinders, and rectangles in a topological photonic crystal corner-state nanocavity. The maximum quality factor Q and minimum effective mode volume V eff of these hybrid nanocavities can reach the order of 10 4 and 10 −4 (λ /n) 3 respectively, and the high figures of merit Q/V eff for all of these hybrid nanocavites are stable and on the order of 10 5(λ /n) −3 . The relative positions of the plasmon nanoantennas will influence the coupling strength between the plasmon structures and the topological nanocavity. The hybrid nanocavity with gold nanospheres possesses much higher Q, but relatively large V eff . The presence of a gold rectangular structure can confine more electromagnetic energy within a smaller space, since its V eff is smallest, although Q is lowest among these structures. This work provides an outstanding platform for cavity quantum electrodynamics and has a wide range of applications in topological quantum light sources, such as single-photon sources and nanolasers.
