본 연구는 비노인층을 대상으로 온라인/오프라인에서 노인혐오표현을 접한 경험 수준과 노인낙인과의 관계에서 가족 및 친척 노인, 가족 및 친척 이외 노인과의 교류경험의 조절효과를 검증하는 것을 목적으로 하였다. 이를 위해 ‘노인혐오차별 실태조사’ 데이터를 활용하여 만 20세-59세 성인 600명을 대상으로 위계적 회귀분석을 실시하였다. 분석결과 첫째, 온라인/오프라인에서 노인혐오표현을 접한 경험 수준은 노인낙인에 정적인 영향을 미치는 것으로 나타났다. 둘째, 오프라인에서 노인혐오표현을 접한 경험 수준과 노인낙인과의 관계에서 가족 및 친척 노인과의 교류경험의 조절효과가 확인되었는데, 가족 및 친척 노인과의 교류경험 수준이 높을수록 오프라인 노인혐오표현을 접한 경험 수준이 노인낙인에 미치는 영향을 강화하는 것으로 나타났다. 이러한 결과를 바탕으로 노인낙인을 줄이기 위한 논의를 제시하였다. The purpose of this study was to examine the moderating effect of the experience of interacting with older people in the family, older people outside the family on the relationship between the level of experience of encountering hate speech against older people in online/offline and stigma of older adults. To this end, the data of the “Survey on hate and discrimination against older people” were used, and a hierarchical regression analysis was conducted on 600 adults aged 20-59 years old. The analysis found that first, the level of experience encountered hate speech against older people online and offline has a static effect on the stigma of older people. Second, the moderating effect of experience of interacting with older people in the family was confirmed on the relationship between the level of experience of encountering hate speech against older people in offline and stigma of older adults. And the higher the level of interacting with older people in the family, the stronger the impact of the level of experience encountered offline hate speech against older people on the stigma of older adults. Based on these results, we present a discussion to reduce the stigma of older people.

The present study investigated the effects of repeated recall and repeated encoding in relation to long-term English vocabulary retention. Korean learners of English were divided into three different learning conditions(Repeated encode-recall, Repeated recall, Repeated encode), and they learned 160 English-Korean word pairs across four sets of study and test trials. A delayed recall test was given one week after the initial learning phase, and the results showed that although the cumulative learning curve was similar in all three learning conditions, Repeated encode-recall and Repeated recall conditions produced greater delayed recall rates compared to Repeated encode condition Moreover, lexical decision test and word completion test were administered to examine word recognition and implicit learning of given words, but no significant group difference was found Hence, this study suggests that repeated testing by engaging in the retrieval process of English vocabulary learning is a stronger determiner for long-term retention.

This study was carried out to identify and compare the antioxidant capacity of three different extraction methods of Cranberry extract (i.e. HWE; hot water extraction; AUE, ultrasonic extraction; EE, 70% ethanol extraction;) and the effect of the human kidney epithelial cell(293T cell) proliferation was examined. Analyses of phenolic compounds were carried out by measuring the total polyphenol, total anthocyanin and proanthocyanidin content. Cell proliferation was determined using WST assay. The results showed a significant increase in the level of phenolic compounds in the Cranberry extract using 70% ethanol(EEE) compared to those using hot water extraction(HWE) or ultrasonic extraction(AUE). The 70% ethanol extraction(EEE) showed proliferation of human kidney epithelial cells compared to those using hot water extraction(HWE) or ultrasonic extraction(AUE). In conclusion, compared to other two extracts, usage of 70% ethanol could improve the nutritional value of Cranberry by enhancing the phenolic compounds and human kidney epithelial cell proliferation. These results suggest that Cranberry extract would have Anti-oxidant effects which needs to be further studied in rodents.

Background Visualizing educational contents makes learning more efficient and effective especially in the area such as molecular toxicology, which is time consuming and intellectually taxing to learn. Objective A design principle based on cognitive neuroscience was developed for spatiotemporality of information and optimized virtual reality (VR) for molecular toxicology. We modeled VR with the tricarboxylic acid (TCA) cycle, a major working mechanism of several toxic poisons such as fluoroacetate, malonate, arsenite, etc. to improve the effectiveness of education in molecular toxicology for better recall compared to traditional education methods. Results We devised an educational system and theoretical basis for virtual reality visualization model (VRVM), as integrated research in this area had been insufficient thus far. We found that VRVM has positive effects on learning and memory when teaching complex topics such as molecular toxicology in our previous study. Conclusions This study has three main components: (1) construction of VR hardware/software (HW/SW) system; (2) creation of VR space design guide; and (3) verification of VRVM spatiotemporality. Consequently, we developed VRVM for the TCA cycle of toxicological mechanism to improve the study habits of medical students in the context of molecular toxicology studies. To continuously expand this approach for future educational applications, up-to-date findings in areas such as cognitive neuroscience and psychology for studying molecular toxicology should be incorporated to strengthen concepts, logic, and physical models of visualization.
