The Web accessibility compliance rate of public organizations and private enterprises is still low due to the lack of awareness of Web accessibility by website developers and managers in spite of the fact that web accessibility compliance became mandatory in 2008. Web developers and managers think the website visual quality might be compromised or the website requires more development time and budget in order to comply with the web accessibility guidelines. Therefore, this paper has analyzed whether developers with various training in web accessibility or experience on website development have different perception on time, cost and design issues for developing accessible websites. For this purpose, 72 Web developers with hand-on experience working for website development companies in Korea were sent to the questionaries. The results have indicated that the group of developers with many hours of training in web accessibility and rich experience on website development perceives that they can develop accessible website without additional cost and time or compromising design quality. The contributions of this paper are following： (1) proving the widely recognized perception on budget, time, and design for developing accessible website is incorrect and (2) motivating further research on this subject in the future.

Fashion brands seek guidelines for effective green advertising messages, considering benefit appeals, brand types, and construal level. However, few studies have explored their simultaneous interplay. Thus, the present study conducted an experiment with a 2X2X2 between-subjects design to investigate how brand type and construal level moderate the mediating role of ad-brand congruency between benefit appeals and purchase intention. A total of 245 Millennials and Generation Z participants completed an online survey, and the data were analyzed using SPSS. A significant three-way interaction was revealed. Low-construal-level messages with concrete content showed disparities between aspirational and accessible brands concerning other-benefit appeals: Accessible brands utilizing other-benefit appeals demonstrated higher ad-brand congruency, while aspirational brands had lower ad-brand congruency. Furthermore, within aspirational brands, self-benefit appeals resulted in higher ad-brand congruency than other-benefit appeals. Finally, a moderated mediating effect was discovered, indicating that brand types and construal level moderated the mediating effect of ad-brand congruency between benefit appeals and purchase intention. The mediating effect was prominent in the context of self-benefit appeals, aspirational brands, and low-construal-level messages. This study highlights the intricate dynamics of the three factors in green advertising, providing valuable insights for crafting more targeted green advertisements.

The group I intron from Tetrahymena thermophila has been demonstrated to employ splicing reactions with its substrate RNA in the trans configuration. Moreover, we have recently shown that the transsplicing group I ribozyme can replace HCV-specific transcripts with a new RNA that exerts anti-viral activity. In this study, we explored the potential use of RNA replacement for cancer treatment by developing trans-splicing group I ribozymes, which could replace tumor-associated RNAs with the RNA sequence attached to the 3' end of the ribozymes. Thymidine phosphorylase (TP) RNA was chosen as a target RNA because it is known as a valid cancer prognostic factor. By performing an RNA mapping strategy that is based on a trans-splicing ribozyme library, we first determined which regions of the TP RNA are accessible to ribozymes, and found that the leader sequences upstream of the AUG start codon appeared to be particularly accessible. Next, we assessed the ribozyme activities by comparing trans-splicing activities of several ribozymes that targeted different regions of the TP RNA. This assessment was performed to verify if the target site predicted to be accessible is truly the most accessible. The ribozyme that could target the most accessible site, identified by mapping studies, was the most active with high fidelity in vitro. Moreover, the specific trans-splicing ribozyme reacted with and altered the TP transcripts by transferring an intended 3' exon tag sequence onto the targeted TP RNA in mammalian cells with high fidelity. These results suggest that the Tetrahymena ribozyme can be utilized to replace TP RNAs in tumors with a new RNA harboring anti-cancer activity, which would revert the malignant phenotype.

Purpose: The diverse users and the increase of power wheelchair users have made it difficult to apply the standards of Wheelchair user accessible toilet rooms for the existing law and BF-certification. To address these issues, the standards of the relevant laws have been improved (Ministry of Health and Welfare, 2018), but there are still many problems. In this study, problems with the standards for Wheelchair user accessible toilet rooms in Korea are analyzed by comparing national and international standards. In addition, improvements to standards for Wheelchair user accessible toilet rooms will be suggested. Method: It presents improvement for standards of Wheelchair user accessible toilet rooms by comparing national, international standard and standards of many countries. Korean standard, International Standard(ISO 21542), American Standard(ADA Standards), German Standard(DIN 18040-1), Austrian Standard($\ddot{O}NORM$ B 1600) and Swiss Standard(Norm SIA 500) were investigated and analyzed. Results: Korea's standards differ from the ISO and the Standards of other countries in many ways, so there is a need for realignment. Specifications for disabled toilets and clear criteria for the size, shape, and location of sanitary appliances in toilets that are practically available to wheelchair users should be provided. Considering the increasing number of disabled toilet users, the installation of various disabled toilet rooms should be considered considering the user characteristics of those who can walk and wheelchair users. Implication: Recent partial improvements to relevant laws cannot meet the requirements of various users. Therefore, comprehensive and clear standard should be presented that take into account changing society and the environment.

Among the many forms of mesoporous materials, thin films are important for the potential applications of this class of materials. Compared with the powder forms, however, there has been relatively little work done on thin films probably because of the lack of suitable and generalized synthetic mechanisms established. In this account, we will review the issues on mesoporous thin films with emphasis on the necessity of forming films with accessible pores from the film surfaces and on mesoporous thin films with metal oxides other than silica. Various methods that have been tried to utilize mesoporous thin films with accessible pores as templates for the synthesis of nanostructured materials are reviewed with the emphasis on the advantages of the electrochemical deposition technique.

To analyze the spray and flame in D.I. diesel engine, the visualizing methods by schlieren photograph and diffused background illumination photograph with high speed camera are applied to optically accessible D.I.diesel engine. Wcaporating spray, spray droplets and brightness flame are taken with high speed camera by visuallizing method in accordance with various suction air temperature and injection time. The spray and flame image on the film was analyzed by image analyzer. The optically accessible D.I. diesel engine had the similar pressure characteristic to the real D.I. diesel engine. Experimental results showed that shadow areas of the evaporating spray were extended at higher suction air temperature, spray droplets had a max. Penetration length and their penetrating patterns were dependent on the surrounding gas temperature, and flame size after ignition was largely governed by the evaporated fuel quantity at ignition point and by the surrounding gas condition due to piston motion.

Telomerase reverse transcriptase (TERT) is an enzymatic ribonucleoprotein that prolongs the replicative life span of cells by maintaining protective structures at the ends of eukaryotic chromosomes. Telomerase activity is highly up-regulated in 85-90% of human cancers, and is predominately regulated by hTERT expression. In contrast, most normal somatic tissues in humans express low or undetectable levels of telomerase activity. This expression profile identifies TERT as a potential anticancer target. By using an RNA mapping strategy based on a trans-splicing ribozyme library, we identified the regions of mouse TERT (mTERT) RNA that were accessible to ribozymes. We found that particularly accessible sites were present downstream of the AUG start codon. This mTERTspecific ribozyme will be useful for validation of the RNA replacement as cancer gene therapy approach in mouse model with syngeneic tumors.

Utilizing the three-dimensional Snyder-Mitchell model with a PT-symmetric potential, we study the influence of PT symmetry on beam propagation in strongly nonlocal nonlinear media. The complex Coulomb potential is used as the PT-symmetric potential. A localized spatiotemporal accessible soliton solution of the model is obtained. Specific values of the modulation depth for different soliton parameters are discussed. Our results reveal that in these media the localized solitons can exist in various shapes, such as single-layer and multi-layer disk-shaped structures, as well as vortex-ring and necklace patterns.
