대표적 열전물질인 비스무스 텔루라이드에 자성원자를 도핑한 합금에 대한 구조 및 전자적 그리고 자기적 성질에 관한 연구는 고효율 열전물질의 개발이라는 목적뿐만 아니라 특이한 자기적 상호작용 규명 및 위상절연체 분야에서도 큰 관심을 끌고 있다. 본 연구에서는 희토류 원자로서 매우 국소화된 f 전자를 갖는 Gd이 Bi을 치환하여 도핑된 비스무스 텔루라이드 합금의 자성 안정성을 밀도범함수(Density Functional Theory)에 입각하여 제일원리적으로 연구하기 위하여 모든 전자(all-electron) FLAPW(full-potential linearized augmented plane-wave) 방법을 이용하여 전자구조 계산을 수행하였다. 전자간 교환-상관 상호작용은 일반기울기 근사법(Generalized Gradient Approximation)을 도입하여 계산하였으며, 국소화된 f 전자를 기술하는 데 필요한 Hubbard+U 보정과 스핀-궤도 각운동량 상호작용은 제2 변분법적 방법을 이용하여 고려하였다. 계산 결과, 강자성 안정성을 보이는 Gd 덩치계와 다르게 이 합금은 강자성과 반강자성의 총에너지 차이가 ~1 meV/Gd 정도의 아주 작은 값으로 얻어져서, 그 자성 안정성은 결함이나 strain 등에 의한 구조변화에 민감하게 의존하여 변할 수 있음을 알 수 있었다. 특히 Gd 스핀자기모멘트는 덩치에서의 값에 비해 감소하였고, Gd에 가장 가까운 Te에 유도 자기모멘트가 형성되는 것으로 미루어 Te를 매개로 한 자성상호작용이 자성 안정성을 결정하는 데에 중요한 역할을 하는 것으로 예측할 수 있었다.

The increase use of smartphones has paved the way for quick dissemination of online information. This has a huge influence on consumers' purchase decision making and the formation of a company's image. As such, this study focuses on product review from mobile beauty applications(apps); in particular, the perceived information authenticity. The purpose is as follows. First, to examine if there is any difference in perceived information authenticity based on the types of product review. Second, to analyze how perceived information authenticity influences brand attitude, purchase intention, and electronic word of mouth(e-WOM) intention. The study targets consumers in their 20s and 30s who have experience buying a product via a mobile beauty app. Three hundred responses are analyzed using SPSS 21.0 and AMOS 18.0. The results reveal that, first of all, consumers derive higher perceived information authenticity from a multi-facet review rather than a double-facet review. Second, among the traits of perceived information authenticity, only a brand's perceived reliability has a significant influence on brand attitude. Third, this brand attitude has a positive influence on purchase intention and e-WOM intention. In conclusion, these findings can serve as an important discussion point for companies developing a mobile beauty app, drawing attention to perceived information authenticity, based on the types of product review.

Purpose: To determine the long-term efficacy of the anti-tumor necrosis factor (TNF) agents, infliximab (IFX) and adalimumab (ADA), in pediatric luminal Crohn's disease (CD) by performing a systematic literature review. Methods: An electronic search was performed in Medline, Embase, and the Cochrane Library from inception to September 26, 2019. Eligible studies were cohort studies with observation periods that exceeded 1 year. Studies that reported time-to-event analyses were included. Events were defined as discontinuation of anti-TNF therapy for secondary loss of response. We extracted the probabilities of continuing anti-TNF therapy 1, 2, and 3 years after initiation. Results: In total, 2,464 papers were screened, 94 were selected for full text review, and 13 studies (11 on IFX, 2 on ADA) met our eligibility criteria for inclusion. After 1 year, 83-97% of patients were still receiving IFX therapy. After 2 and 3 years the probability of continuing IFX therapy decreased to 67-91% and 61-85%, respectively. In total, 5 of the 11 studies subgrouped by concomitant medication consistently showed that the probabilities of continuing IFX therapy in patients with prolonged immunomodulator use were higher than those in patients on IFX monotherapy. Conclusion: This review of real-world evidence studies confirms the long-term therapeutic benefit of IFX therapy in diverse cohorts of children with luminal CD. Moreover, it supports the view that combination therapy with an immunomodulator prolongs the durability of IFX therapy in patients who previously failed to recover following first-line therapy. The limited number of time-to-event studies in patients on ADA prevented us from drawing definite conclusions about its long-term efficacy.

Objectives: The aim of this study is to develop a methodology for estimating a nationwide statistic for hernia operations with using the claim database of the Korea Health Insurance Cooperation (KHIC). Methods: According to the insurance claim procedures, the claim database was divided into the electronic data interchange database (EDI_DB) and the sheet database (Paper_DB). Although the EDI_DB has operation and management codes showing the facts and kinds of operations, the Paper_DB doesn't. Using the hernia matched management code in the EDI_DB, the cases of hernia surgery were extracted. For drawing the potential cases from the Paper_DB, which doesn't have the code, the predictive model was developed using the data mining technique called SEMMA. The claim sheets of the cases that showed a predictive probability of an operation over the threshold, as was decided by the ROC curve, were identified in order to get the positive predictive value as an index of usefulness for the predictive model. Results: Of the claim databases in 2004, 14,386 cases had hernia related management codes with using the EDI system. For fitting the models with applying the data mining technique, logistic regression was chosen rather than the neural network method or the decision tree method. From the Paper_DB, 1,019 cases were extracted as potential cases. Direct review of the sheets of the extracted cases showed that the positive predictive value was 95.3%. Conclusions: The results suggested that applying the data mining technique to the claim database in the KHIC for estimating the nationwide surgical statistics would be useful from the aspect of execution and cost-effectiveness.
