This study attempted to explore and examine a new user experience (UX) research method for IoT products which are becoming widely used but lack practical user research. While user experience research has been traditionally opted for survey or observation methods, this paper utilized big data analysis method for user online reviews on an intelligent agent IoT product, Amazon's Echo. The results of topic modelling analysis extracted user experience elements such as features, conversational interaction, and updates. In addition, regression analysis showed that the topic of updates was the most influential determinant of user satisfaction. The main implication of this study is the new introduction of big data analysis method into the user experience research for the intelligent agent IoT products.

This study is a user experience study based on location branding at mobile experience stores. As mobile devices have recently become saturated beyond the penetration, the IT industry is encouraging users to buy through experience and can be competitive by increasing brand loyalty through experience stores. The purpose of this study is to analyze the effect of place branding among experience stores through qualitative and quantitative measurements and analyze the user experience factors related to the location branding to present a future direction. A total of eight subjects were given tasks and then experimented with participatory observations and conducted in-depth interviews. The experiment showed that the experience had a significant effect on users, but the difference between each brand was obvious. Since this study has identified the experience-oriented elements, we expect to provide better service and experience for future users.

바이링걸의 인지증고령자와의 보다 유효한 커뮤니케이션의 가능성의 검토를 목적으로, 이문화를 배려한 모국어에 의한 개인 회상법을 이용한 회화를 실시했다. 회화는, 재일 코리안의 문화를 배려한 특별 양호 노인홈에 입주중이며 중도의 인지증 바이링걸 고령자 4명(모두 여성, 평균 88세)의 협력하에 실시했다. 모국어와 일본어의 장면에서, 개인 회상법에 의한 회화 내용과 감정 표출에 차이가 발생하는가의 관점에서 양 회화장면의 비교 분석을 실시했다. 그 결과, 중증의 인지증고령자라고해도 바이링걸의 특징인 자연스러운 코드 스위칭(Code-Switching;CS)가 관찰되었다. 즉, 과거의 학습이나 경험에 의해 축적된 모국의 언어 형식을 사용하는 기능이 잔존 능력으로서 잠재하고있는 것이 밝혀졌다. 덧붙여 ERiC 감정 반응 평가 척도를 이용해 관찰한 결과, 일본어의 장면보다 모국어의 장면에 대해 긍정적 감정의 풍부함이 관찰되었다. 이상으로, 바이링걸의 재일 코리안 인지증고령자 1세와 모국어를 이용한 회상법에 의한 회화는, 바이링걸의 특징을 기초로한 하나의 유효한 어프로치라고 생각된다.

다이캐스팅과 같이 가압 사출방식을 이용한 제품 성형 공정에서 관심의 대상이 되어왔던 연구 주제 중 하나는 어떻게 하면 금형 내에 충진되는 용탕의 유동을 층류성으로 제어할 수 있을까 하는 문제이다. 그러나 다이캐스팅 공정에서 일반적인 용탕의 사출속도로는 그 유동 특성을 제어하기가 거의 불가능하다. 이러한 사출속도의 설정 및 게이트의 형상설계를 하는데 있어서 대부분 경험적인 자료를 이용하고 있어 공정의 효율성을 극대화하고 있지 못한 실정이다. 본 연구에서는 용융 마그네슘합금이 금형내에 충진 될 때 유체의 유입속도 및 탕구형상이 유동에 미치는 영향을 전산유체역학을 이용하여 충진 및 응고해석을 하였고, 예견되는 제품의 결함 및 결함제어 가능성을 진단함으로써 개선방안을 제안하고 최종적으로 금형설계 제작에 반영하여 실제 주조된 제품을 해석결과와 비교하였다. 또한, 본 연구에서 주조된 전자기부품의 미세조직을 관찰하고, 인장강도 및 파괴 특성을 관찰 하였다. 실험결과 빠른 응고속도에 따른 조직의 미세화 효과로 항복강도, 인장강도 그리고 경도 특성이 우수하게 관찰되었다.

The purpose of this study was to use phenomenological perspectives to identify the meaning and structure of the observational experience of labor and delivery by student nurses in the clinical setting. The participants were 115 junior and senior students from Christian College of Nursing in Kwang Ju. The students were asked to write about their observational experience in the delivery room. Colaizzi's method was used for phenomenological analysis. The investigator analysed the data to identify and categorize themes and basic structural elements. Twelve themes and eight basic structure were identified. The process of the observational experience in labor and delivery has three proposed phases : anticipatory, observational and post-observational. In the anticipatory phase, nursing students were related only to the event of anticipated labor and delivery of clients. Structure 1, feeling of expectation and fear, was identified. In the observational phase, students were related to the labor and delivery situation, a woman delivered and a newborn. Structure 2, shock and suffering, was identified in relation to the labor and delivery situation. Structure 3, need for caring and satisfaction, was identified in relation to the woman delivered. Structure 4, feeling of mystery and joy, was identified in relation to the newborn. In the post-observational phase, relations between students and the life of a human being, students and self in the future, students and their mothers and students and women and God appeared. And in these relations 〈structure 5, valuable〉, 〈structure 6, feeling of expectation and fear〉, 〈structure 7, love and appreciation〉 and 〈structure 8, greatness〉 were identified.

This study is to perform empirical analysis on observational before-after studies in Naive Method, Comparison Group(CG) Method and Empirical Bayes(EB) Method, and to compare with their results and to propose ways to apply to evaluation researches. For this purpose, the evaluation of road safety audit executed on Y$\breve{o}$ng-dong freeway in 2005 and 2006 was performed. As a result, all three methods have showed improved effects due to safety treatments. The safety effectiveness of Naive method is the largest, CG Method is the second and EB method is the last. The results of Naive method are overestimated due to the trend of reducing traffic accidents and those of CG method are affected by the external casual effects of comparison group. In the EB method, as "regression to the mean" phenomenon are controlled by reference group's accident model, it's result is relatively more accurate than that of other methods. In the conduct of evaluation studies, the analysts have to understand the pros and cons of each evaluation method. And after leading the survey on accident trends of related all sites, evaluation analysis is performed to be able to minimize bias.

What are the identification criteria elementary school teachers prefer? What are the characteristics of students that teachers consider when nominating them to gifted programs? Will those criteria of identification/nomination differ as to teacher experiences related to gifted education or teacher involvement in the professional development? This study aims to find the answer to these questions. For this purpose, a total of 511 elementary school teachers with a varying degree of experiences with gifted education were recruited from 23 schools in 11 school districts in Seoul. The results show that teachers generally preferred task commitment, creativity, curiosity, and domain specific talents as criteria for identifying gifted students, while perceiving achievement records, total grades, leadership, and general intelligence as less important. Teachers experienced in gifted education or having been involved in professional development perceived curiosity, task commitment, and creativity as more important than teachers without such experiences. The importance-performance analysis of identification criteria indicates that teachers reported high importance on task commitment, curiosity, and creativity, but those factors were less considered in actual nomination. On the contrary, teachers reported low importance on quick learning and achievement(total grades, subject grades), but those were highly considered in nomination. A similar pattern was found in both experienced and nonexperienced teachers although the importance-performance gap was higher for the latter. Implications for teacher nominations and professional development were discussed.

"Time versus money effect" refers to a favorable shift in consumers' responses activated by time(vs. money). In general, how people spend their time or money could reflect one's personal identity. Previous research indicates that drawing individuals' attention to time makes more effective in product satisfaction rather than money. Also, whereas because time is experienced as an experience, time activates more positive product satisfaction for experiential product rather than materialistic product, money has the reverse effect because money relates with possessions. Present study examined the effect of time and money on consumers' attitudes and decisions and the role of product type including smartphone. In experiment 1, participants evaluated their experiences or their own products(family restaurant, smartphone, premium jean). They satisfied more with their smartphones when activated by time than by money. In experiment 2, 3 image ads, a promotion image ad for each product(family restaurant, smartphone, premium jean), were offered to find the effect of time and money in promotion ads. The interaction effects between activating condition and product type were revealed on the product attitudes, product satisfaction, purchase intent, and personal connection reflecting the consistent time effect on smartphone. In addition, the main effect of the activating condition was significant which meant time activating ads were more effective than money activating ads.
