One of the most promising emerging technologies for the next generation of nonvolatile memory devices based on resistive switching (RS) is the resistive random-access memory mechanism. To date, RS effects have been found in many transition metal oxides. However, no clear evidence has been reported that ZnO-based resistive transition mechanisms could be associated with strong correlation effects. Here, we investigated N, F-co-doped ZnO (NFZO), which shows bipolar RS. Conducting micro spectroscopic studies on exposed surfaces helps tracking the behavioral change in systematic electronic structural changes during low and high resistance condition of the material. The significant difference in electronic conductivity was observed to attribute to the field-induced oxygen vacancy that causes the metal-insulator Mott transition on the surface. In this study, we showed the strong correlation effects that can be explored and incorporated in the field of multifunctional oxide electrons devices.

To compete with the growth of fashion shopping platforms in the online fashion market, general shopping platforms have begun to expand their product categories to include fashion items. This research examines the characteristics that influence consumers' trust in each of these platforms and their intention to reuse them. Applying the concept of platforms, this study also distinguishes between general shopping platforms and fashion shopping platforms and compares their characteristics. This study surveyed 788 consumers in their 20s and 30s with experience in using general shopping platforms or fashion shopping platforms (389 and 399 respondents, respectively). SPSS was used to conduct frequency analysis, factor analysis, and cross-tabulations, and AMOS was used to conduct confirmatory factor analyses and structural equation analyses. The results were as follows: platform reputation, shopping convenience, and interactivity all influenced consumer trust. For fashion shopping platforms, the product quality factor significantly improved consumer trust. However, for general shopping platforms, the product quality factor only influenced reuse intentions to reuse and did not contribute to improving trust. Platform reputation and information offering have influenced reuse intentions for both shopping platforms. Regardless of the type of shopping platform, platform reputation has influenced reuse intentions and consumer trust, and platform esthetics didn't have affect consumer trust and consumers' reuse intentions. Consumer trust influenced the intention to reuse on both platforms.

Purpose - This research examined the effect of hedonic and utilitarian eating-out motivations on the evaluation of restaurant selection attributes in a fashion premium outlet. Additionally, the influence of experimental and functional attributes on customers' preference for hedonic eating-out motives and utilitarian eating-out motives, and variation of moderating effects through the gender was examined. Research design, data, and methodology - A survey was conducted to verify the established research hypothesis. The questionnaire items for the research were modified to fit the situation of the present study. In order to elaborate the questionnaire, the literature of the previous researchers was reviewed and supplemented. The survey conducted 207 online questionnaires for consumers who have visited domestic fashion premium outlets from July 4, 2017 to July 27, 2017. A total of 207 questionnaires were collected, and a total of 206 questionnaires were used for the empirical analysis after excluding one inappropriate response. In order to verify the reliability and validity of the measured variables, exploratory factor analysis and reliability analysis were performed using SPSS 20.0. Next, the structural equation model (SEM) statistical method was used to test the hypotheses of the study. Results - Hedonic motivation had more influence on experimental attribute importance than the functional attribute importance of the restaurant. However, this result was different depending on the gender. The effects of hedonic motives on empirical attributes were more influenced by female groups, and when influencing functional attributes, male groups were more influenced. However, it was statistically significant (p <0.05) in the female group only when the hedonic eating out motives influenced empirical attributes. Conclusions - This study analyzed the effect of eating-out motivation on the restaurant preference attributes and suggested practical implications. First, customers with hedonic eating-out motivations were evaluating experiential attributes to be more important than functional attributes. Second, for customers who are motivated to use practical eating-out habits, companies should provide services that meet practical and economic needs. In particular, female customers visiting restaurants need differentiated marketing strategies that make them feel new experiences rather than practical ones. In addition, it is necessary to study more complex and integrated studies which will influence restaurant selection attributes of premium outlets customers by adding various eating out motives and selection attributes.

The National Museum of Korea's 'Shinchungmyeong Jochong' is the sole firearm in the country bearing inscriptions written in ink('辛丑改備江華庫藏'). Thanks to this written record, it is possible to determine where this firearm was stored and to make an estimate of the time when it was stored. Additionally, it is a valuable artifact that has been exceptionally well preserved and has an artistic design. However, research into the operational period, form, and structural characteristics of this firearm has been limited to date. This study aimed to shed light on the operational period, form, and structural features of the 'Shinchukmyeong Jochong.' To achieve this, the specifications and structural characteristics of the firearm were examined, and comparisons were made with 17 other extant firearms and their attributes. The results confirmed that the 'Shinchungmyeong Jochong' is a representative example of the typical firearms of the Joseon Dynasty. Next, the timing, background, and production subject of the Ganghwado containment of the Jochong were tracked based on letters found with the Jochong. The investigation revealed an entry in the 'Records of King Jeongjo'(『正祖實錄』) indicating that a significant amount of military supplies, including firearms, were stored on Ganghwado in December of the 5th year of Shinchung(1781). The decision to store these materials in Ganghwado Island may have been due to the perception of the Joseon decision-makers, who strategically valued Ganghwado Island, and the relocation of 'Tongaoyeong'(統禦營) and the integration with 'Jinmuyeong'(鎭撫營). After acquisition, it is presumed that the firearm was operated at locations like 'Jinmuyeong'(鎭撫營). The firearm's production is presumed to have been associated associated with institutions such as 'Gungisi'(軍器寺). In conclusion, the 'Shinchungmyeong Jochong' exemplifies a typical firearm of the Joseon Dynasty, and it is likely that it was stored on Ganghwado in December of 1781. Its production is believed to have been related to institutions such as 'Gungisi'. Following its acquisition, it is presumed that the firearm was operated at locations including 'Jinmuyeong'.
