As the importance of online virtual spaces increases due to COVID-19, interest in online virtual spaces using 4th industrial technology is increasing. Accordingly, the metaverse that combines virtual and real is becoming an issue. In the fashion industry, marketing using online is gradually increasing, and various attempts are being made by converging with the metaverse to provide new and enjoyable experiences to customers. This study looked at the impact of customer experience of a luxury fashion brand pop-up store on customer satisfaction, affective commitment and brand loyalty in a metaverse environment where utilization is increasing due to COVID-19 and technological development. For the analysis data of this study, a survey was conducted on the users who experienced the metaverse platform Zepeto's ' BVLGARI World'. As a result of examining the effect of the customer experience of a luxury fashion brand pop-up store on customer satisfaction, affective commitment, and brand loyalty in a metaverse environment, some of the customer experiences affect customer satisfaction, and the proposed hypothesis was partially accepted. In addition, it was confirmed that customer satisfaction affects affective commitment and brand loyalty, and affective commitment affects brand loyalty. In this study, we examine the impact of the customer experience of a luxury fashion brand pop-up store on customer satisfaction, affective commitment, and brand loyalty in the metaverse environment, and identify what is needed for more active convergence and activation of the metaverse and fashion brands. Also, we provide practical implications to people who involved in the metaverse and the fashion industry.

The purpose of this study was to analyze the effects of manual therapy on lower extremity alignment in pelvic malalignment. The subjects were 20 adults with pelvic malalignment. They were divided into two groups: manual therapy group (n=10) and stretching exercise group (n=10). Each group performed the intervention two times per week for 4 weeks. The lower extremity alignment was measured by pelvic deviation, functional leg length inequality, and plantar pressure distribution, which were measured between pre- and post-test. In the result of pelvic deviation, there was a significant difference between the pre- and post-test of the manual therapy group and stretching exercise group. In the result of the functional leg length inequality, there was a significant difference between the pre- and post- test of the manual therapy group. In the result of plantar pressure distribution, there was a significant difference between the pre- and post- test of the manual therapy group. These findings suggest manual therapy improves the pelvic deviation, functional leg length inequality, and plantar pressure distribution in the pelvic malalignment.

Electromagnetic interference (EMI) shielding is an important issue in modern daily life due to the increasing prevalence of electronic devices and their compact design. This study estimated EMI-shielding effect (EMI-SE) of small (8–14×17 mm) Hanji (Korean traditional paper) doped with carbon nanotubes (CNTs) and compared to Hanji without CNT using 2H (92.1 MHz) and 23Na (158.7 MHz) nuclear magnetic resonance (NMR) peak area data obtained from 1 M NaCl in D2O samples in capillary tubes that were wrapped in the Hanji samples. The simpler method of using the variation of reflected power and tuning frequency by inserting the sample into an NMR coil was also tested at 242.9, 158.7, and 92.1 MHz. Overall, EMI shielding was relatively more effective at the higher frequencies. Our results validated that NMR methods to be useful to evaluate EMI-SE, particularly for small, flexible shielding materials, and demonstrated that EMI shielding by absorption is dominant in Hanji mixed with CNT.

감귤그린병(Citrus Huanglongbing Disease)은 전 세계적으로 감귤산업에 가장 큰 피해를 주는 병해로 국내 미분포종인 귤나무이(Diaphorina citri Kuwayama)가 매개충으로 알려져 있다. 바이러스에 감염된 나무는 5~12년내에 대부분 고사하며 열매는 크지 못하고 색이 들지 않는 증상을 보여 상품성을 저해시킨다. 현재 접목, 묘목, 매개충등의 유입으로 전 세계적으로 확산되고 있는 실정이다. 귤나무이의 국내 분포가능성이 꾸준히 제시되면서 유입 대비를 위한 예찰방법 및 동정법 개발이 필요한 실정이다. 제주도에는 총 33종이 분포하는 것으로 알려져 있으며(권, 1983; Cho & burckhardt, 2017) 2016년부터 지금까지의 조사로 11종의 나무이와 10종의 기주식물을 확인되었다. 귤나무가 속해있는 운향과를 기주로 하는 나무이는 발견되지 않았다.

Apolipophorin III (apoLp-III) is a well-known hemolymph protein having a functional role in lipid transport and immune response of insects. We cloned full-length cDNA encoding putative apoLp-III from larvae of the coleopteran beetle, Tenebrio molitor (TmapoLp-III), by identification of clones corresponding to the partial sequence of TmapoLp-III, subsequently followed with full length sequencing by a clone-by-clone primer walking method. The complete cDNA consists of 890 nucleotides, including an ORF encoding 196 amino acid residues. Excluding a putative signal peptide of the first 20 amino acid residues, the 176-residue mature apoLp-III has a calculated molecular mass of 19,146 Da. Genomic sequence analysis with respect to its cDNA showed that TmapoLp-III was organized into four exons interrupted by three introns. Several immune-related transcription factor binding sites were discovered in the putative 5’-flanking region. BLAST and phylogenetic analysis reveals that TmapoLp-III has high sequence identity (88%) with Tribolium castaneum apoLp-III but shares little sequence homologies (<26%) with other apoLp-IIIs. Homology modeling of Tm apoLp-III shows a bundle of five amphipathic helices, including a short helix 3’. The ‘helix-short helix-helix’ motif was predicted to be implicated in lipid binding interactions, through reversible conformational changes and accommodating the hydrophobic residues to the exterior for stability. Highest level of TmapoLp-III mRNA was detected at late pupal stages, albeit it is expressed in the larval and adult stages at lower levels. The tissue specific expression of the transcripts showed significantly higher numbers in larval fat body and adult integument. In addition, TmapoLp-III mRNA was found to be highly up-regulated in late stages of L. monocytogenes or E. coli challenge. These results indicate that TmapoLp-III may play an important role in innate immune responses against bacterial pathogens in T. molitor.

14-3-3 proteins are known to play a pivotal role in a diverse array of cellular events such as cell survival, apoptosis, and signal transduction. Numerous 14-3-3 ζ have been cloned and characterized from a host of eukaryotic organisms including human, plants, yeast, fruit fly and silkworm. However, no study on Spodoptera exigua 14-3-3ζ in conjunction with virus infection has so far been reported in insects. It appears that expression of Se14-3-3ζ was decreased starting 24 h post-SeNPV infection as SeNPV titers seemed to increase as evidenced by intense bands of SeNPV IAP3. Interestingly, confocal microscopic analysis revealed that Se14-3-3ζ is expressed at the apical side of the NPV-uninfected gut cells, whereas it was detected mainly in the nucleus of the NPV-infected cells. Thus, despite the biological significance of Se14-3-3ζ in S. exigua in conjunction with molecular interactions between SeNPV and S. exigua is unclear now, our data suggest that Se14-3-3 ζ protein plays a role to protect S. exigua from the infection or inhibit replication of SeNPV.

Janus kinase-signal transducer and activator of transcription (JAK-STAT) signaling pathway is known to play a pivotal role in various cellular events and antiviral responses in both vertebrates and insects. In an attempt to elucidate the potential involvement of STAT on S. exigua-SeNPV interactions, the full length cDNA of SeSTAT was cloned from S. exigua. Analysis of temporal expression patterns shows that SeSTAT is expressed in all stages of life cycle such as larvae, pupae, and adult. Spatial expression analysis shows that it is highly expressed in fat body and Malpighian tubule. Interestingly, SeSTAT is induced at 24 h in response to either laminarin or LTA injection in larvae. Electrophoretic mobility shift assay (EMSA) shows that the binding of nuclear extracts from fat body cells immune-challenged with LTA to STAT5 probe was observed. In addition, SeSTAT was nuclear-translocalized in both fat body and gut cells that were challenged with LTA and laminarin, respectively. Finally, gene silencing of SeSTAT shows that SeNPV number appears to be increased. It suggests that SeSTAT may act as a negative regulator against SeNPV in midgut.

Background : This study is designed to select the best shading materials for the 4-year old ginseng K-1 variety by examining the light volume, photosynthesis and growth characteristics of ginseng. Methods and Results : The ginseng seedling was transplanted in the 7 lines x 9 rows (63 plants)/ 1.65 ㎡. The shading materials were installed in the form of rear line with 170 ㎝ high for front pole and 100 ㎝ high for rear pole. The installation of shading materials were installed in combination of polyethylene, blue polyethylene sheet + polyethylene, polyethylene + polyethylene, polyethylene + aluminium screen 70%, polyethylene + aluminium screen 100%, aluminium shade plate to inspect the photosynthesis and ginseng's growth characteristics. The photosynthetic rate was measured on the middle of small leaf using the photosynthetic tester (L1-6400, Li-COR) a t 10 : 00 – 14 : 00 on a clear day with the light volume of 100, 200, 400, 600, 800, 1,000, 1,400, 1,800 μmol s-1m-2.For the ginseng K-1, which is 4-years old, the aerial parts growth (such as survival rate, height of plant, length of stem, diameter of steam and length of leaf) and underground part (length, diameter and weight of root) were examined in 2016. As for the PAR (photosynthetically active radiation), the aluminum shade plate showed the best performance while the polyethylene + polyethylene showed the least. As for the photosynthetic rate, the following order was shown in the decreasing order: blue polyethylene sheet + polyethylene > polyethylene > aluminium shade plate ≒ polyethylene + aluminium screen 100%, > polyethylene + polyethylene > polyethylene + aluminium screen 70%. As for the survival rate for 4-year old ginseng, the polyethylene + aluminium screen 70% showed the highest survival rate with 91.0%. As for the growth of aerial part of ginseng, the polyethylene and polyethylene + polyethylene showed the best growth. As for the underground part of ginseng, the polyethylene, blue polyethylene sheet + polyethylene, and polyethylene + polyethylene showed the best growth in the length of roots and length of main root while polyethylene and blue polyethylene sheet + polyethylene showed the best growth in the weight of roots. Conclusion : In conclusion, considering the characteristics of photosynthesis and the underground parts of ginseng, it was found that the best shading materials for K-1 4-year old ginseng is blue polyethylene sheet + polyethylene.
