As COVID-19 spread widely, and rapidly, the number of misinformation is also increasing, which WHO has referred to this phenomenon as "Infodemic". The purpose of this research is to develop detection and rectification of COVID-19 misinformation based on Open-domain QA system and text similarity. 9 testing conditions were used in this model. For open-domain QA system, 6 conditions were applied using three different types of dataset types, scientific, social media, and news, both datasets, and two different methods of choosing the answer, choosing the top answer generated from the QA system and voting from the top three answers generated from QA system. The other 3 conditions were the Closed-Domain QA system with different dataset types. The best results from the testing model were 76% using all datasets with voting from the top 3 answers outperforming by 16% from the closed-domain model.

드라마 제작에 있어서 스타배우의 기용은 드라마 수익의 중요한 요건인 시청률 확보에 있어서 중요한 원천이 되지만 이와 동시에 드라마 비용 상승의 중요한 원인이 되기도 한다. 그러므로 어떠한 상황에서 스타배우를 기용하는가에 대해 조사하는 것은 드라마 기획 과정에서 불확실성을 관리하는 방식에 대해 파악하는 단서가 될 수 있다. 본 연구는 한국에서 방영된 텔레비전 드라마를 대상으로 하여 드라마의 스타배우의 기용에 영향을 미치는 요인들에 대하여 분석하였다. 분석 대상으로 2014년 1월부터 2017년 12월까지 공중파 방송 3사와 케이블 방송사에서 방영이 완결된 288편 드라마를 선정하였다. 스타배우 기용에 영향을 미치는 요인으로서 드라마의 방영기간, 즉 드라마의 횟수에 주목하였으며 원작 유무, 외주제작 여부와 PD의 수상 경력의 조절효과도 조사하였다. 그 결과 단편드라마의 경우 스타배우가 기용되며 특히 원작이 존재하는 단편드라마가 원작이 있는 경우에 스타배우를 더욱 기용하는 것으로 나타났다. 이는 광고 수익의 가능성이 큰 스타배우를 기용하는 것에 따르는 높은 출연료의 부담을 덜기 위한 불확실성 감소의 수단으로 방영기간이 짧고 스토리가 검증된 원작을 사용하는 드라마 제작이 이루어지는 것으로 해석된다.

For data analysis SPSS 17.0 statistical program was used, and principal component analysis, frequency analysis, ${\chi}^2-test$, ANOVA test and Duncan test were conducted. The results and conclusions of this study are as follows: first, cosmetics store use by product type was examined. Department stores were used most often to purchase skincare, base and color products, while large cosmetics stores were used most frequently to buy hair and body products. Second, The result of the differences in choosing brand by type of cosmetics has found that there are the meaningful differences between Korean low and middle priced brands and foreign high priced ones in skincare and base products. The Korean low and middle priced brands of skin care products show that various distribution routes are simultaneously and highly used as choices in internet, cosmetics specialty stores and large general ones are higher than other distribution routes. Color products have found that there are the meaningful differences in the entire brands. Hair and body products have found that there are the meaningful differences in three brands except the Korean high priced brands. Third, the differences in cosmetics store selection by age were investigated. As for online purchasing, people in their 20's were most likely than other age groups to purchase online.

Purpose - When indulging in hedonic items is construed as wasteful and evokes anticipated regret or guilt, consumers are more likely to seek reasons to justify their indulgence. Justification requirement for spending on indulgences over necessities could lead to the places of their finding the ways that mitigate the anticipated regret and guilt. However the previous research focusing on consumers' own great effort leading to positive outcomes has not given much attention to other's outcomes induced from his or her little or no efforts, by which consumers could feel envy. The guilt associated with consumers' indulgence could vary according to envy type felt according to their evaluation about other's outcomes and their self construal level. Current research explored the envy type's effects on consumers' spending on hedonic products, and moderation effects of self construal level on the envy type's effects. Research design, data, and methodology - 2(envy type: benign versus malicious) × 2(self construal level: high versus low) between-subjects design was employed. Data for empirical analysis were from 173 undergraduate participants. ANOVA was used to verify hypotheses. Results - The tendency of choosing utilitarian product versus hedonic product was moderated by the envy type. The participants who felt benign envy were more likely to choose utilitarian product versus hedonic product than those who felt malicious envy were. And the tendency of benign envy-felt participants' choosing hedonic versus utilitarian product was more weakened to those with lower-level self construal than to those with higher-level self construal. However the tendency of malicious envy-felt participants' choosing hedonic versus utilitarian product was not moderated by the self construal level. Conclusions - This research could advance the theory related to indulgent hedonic consumption by exploring the effects of self construal level and envy type on hedonic indulgence. In view of the results from current study, marketers should make efforts of communicating and selling utilitarian products to persuade consumers with lower-level construal when they feel benign envy to others. And they should conduct marketing acts for hedonic products to persuade consumers when they feel malicious envy to others.

Advances in healthcare technology and rapid economic growth lead to the increased life expectancy and consequently the size of elderly population. Korea is one of the countries that are rapidly aging. Thus, it is particularly important to prepare for the aging society. Recently, the number of healthcare institutions for the elderly citizens has increased. The purpose of selecting a hospital for the elderly is, in general, maintenance of health rather than improvement of health receiving proper treatment. Unlike choosing a hospital for treatment, customers of a long term care hospital have a different set of factors to consider. Especially, when choosing a long term care hospital, the influence of patient's family is greater than the patient. This study examines the factors they consider for long term care hospital. A total of 198 questionnaires were collected from the families of actual patients of long term care hospitals. Twelve questionnaires were found to be non-usable because of missing and unsatisfactory responses. Consequently, 186 questionnaires were used for the analyses. Findings of this study are as follows. First, seven factors have been identified to consider when choosing a long term care hospital for the elderly. They include convenience of facilities, costs variety of facility programs, service hours, reputation, accessibility, quality of medical staff, medical facilities, and facility size. Second, This study measured both importance and satisfaction with these attributes and analyzed the difference between them. Satisfaction was lower than importance in the categories of convenience of facilities, costs, and programs, and accessibility. On the other hand, satisfaction was higher in terms of service hours, reputation, and quality of medical staff. Finally, the current study found positive impact of accessibility and quality of medical staff on reuse intention of a long term care hospital.
