본 연구는 능동적 IPA(지능형 가상 비서)가 탑재된 Google의 Nest Hub Max의 사용 행태별 사용자 경험 분석을 위한 질적 연구이다. 근거이론 방법론에 착안하여, 한 달 동안 해당 기기를 사용한 6명의 연구 참여자를 대상으로 인터뷰를 진행하였다. 총 186개의 개념이 추출되었으며, 24개의 하위 범주와 11개의 상위 범주로 정리되었다. 개방 코딩을 통해 축 코딩을 이용한 패러다임 모형을 제시하였고 선택 코딩을 거쳐 사용 행태 유형을 구분하였다. 그 결과, 능동적 IPA의 소극적 사용자와 적극적 사용자 유형을 도출하였으며, 유형별 해당 기기의 사용자 경험을 분석하였다. 유형별 다른 사용 행태의 패러다임을 보였으나 결론적으로 소극적 사용자와 적극적 사용자는 모두 해당 기기의 능동적 IPA로부터 긍정적인 사용 경험을 유발하지 못하였다. 본 연구는 앞으로 출시될 능동적 IPA가 탑재된 기기 및 서비스의 사용자 경험 설계를 위한 기초 자료를 제시하였다. This is a qualitative study about Google 'Nest Hub Max' that displays proactive intelligent personal assistant. Following the step of grounded theory, an in-depth interview for 6 users who had used this device for a month was taken. 186 concepts were discovered, categorized as 11 top-categories and 24 sub-categories. Paradigm diagram, considering axis-coding, was made and it have been narrowed down to 'Usage patterns' of proactive IPA, considering selective coding aspects. 'Usage patterns' were divided to passive and active user. Thus, neither passive user nor active user was satisfied about device and proactive IPA. This study is meaningful that it constructed basic data about the user experience of proactive IPA on this device. It will support the device or service that consists proactive IPA in the future.

Background As a new industrial era begins, it is inevitable to understand how it affect to industrial design area. The purpose of this study is to qualify the new design process and element that new A.I based design tools should have by researching several changes of Industrial design area. Methods Both literature review and case study has been hold. For literature review, research for Industrial revolution in chronological order have been studied at first. Case study design software and generative design take next. Furthermore, limitation of software for generative design was deduced by comparing traditional design process and design process based on A.I. Results The appearance of software for generative design based on A.I let designers to work more effectively. Nevertheless, better working effectiveness did not mean better design. Software for generative design is known as creative assistant that helps designers, however, role for formative creativity or sensitivity was extremely tenuous and poorly researched. Conclusion New design tool for Generative design in the future has to take a role as a supporter to make better use of designers’ empathy ability and booster to better cooperate.

This study aims to provide an overview of first-year composition programs in U.S. universities, including both their origin and development as well as their current status and future. While the former is examined through literature review, the latter is explored through a survey of coordinators and directors of writing programs in U.S. universities. The results of these investigations reveal that the first-year composition program is a product of U.S. universities’ continuous efforts to deal with new types of students in every stage of its history since the late 19th century. This investigation of writing programs in U.S. universities can serve as a base for future research, including how English writing programs have developed in Korea and where they should go in the future.

Objective. To estimate drug persistency and the safety of TNF blocker in Korean patients with rheumatoid arthritis. Methods. Data were extracted from medical records of rheumatoid arthritis patients who had treated with TNF blocker or are currently using TNF blocker at Hanyang University Hospital for Rheumatic Diseases from December 2000 to November 2009 (REtrospective study for Safety and Efficacy of Anti-RA treatment with biologiCs, RESEARCh). Comprehensive chart reviews were undertaken on all patients and data on drug usages and response of TNF blocker was collected at initiation, 3 months and the time of data collection. Persistency with treatment was examined using life-table analysis and multivariate Cox proportional hazard models were developed to examine potential predictors of discontinuation of TNF blocker. Result. A total of 268 patients were enrolled in this retrospective study. Among them 180 patients were included in the analysis of drug persistency. The 1-year and 5-year drug persistency of TNF blocker was 74% and 46%, respectively. Concomitant use of methotrexate (hazard ratio 0.46, 95% CI 0.27-0.80) was associated with higher persistence. Comparing to etanercept, adalimumab is an independent risk factor for discontinuation (hazard ratio 2.63, 95% CI 1.43-4.84). Conclusion. Five-year drug persistency of TNF blocker was 46% and concomitant use of methotrexate is associated with higher persistence.

Objective. To examine the impact of patient education (PE) on patients’ satisfaction in rheumatoid arthritis (RA) and to compare nurse-led education with medical doctor (MD)-led education. Methods. Patients were enrolled by categorizing in two groups, nurse-led and MD-led education, randomization was performed. Face-to-face education was conducted two times, and changes in patient satisfaction before and after PE were assessed using the visual analogue scale (VAS; 0 to100 mm) and patients’ satisfaction questionnaire (PSQ). Changes in patients’ reported outcomes (PRO) were measured using disease activity score with 28 joint-erythrocyte sedimentation rate (DAS28-ESR), health assessment questionnaire (HAQ), and European quality of life-5 dimension (EQ-5D). Changes in patients’ satisfaction and PRO between before and after PE were compared using paired t-test, and the comparison between nurse-led and MD-led education was analyzed using independent t-test. Results. A total of 120 patients, 60 patients from each group, were randomized to receive either nurse-led or MD-led education. Among them, 113 patients completely received education and final assessment. In total patients, patients’ satisfaction was significantly increased from 87.8±13.1 mm to 92.3±8.8 mm in VAS (p<0.01), and from 3.7±0.4 to 4.0±0.4 in PSQ (p<0.01). There was no improvement in DAS28-ESR, HAQ, but there was mild improvement in quality of life (QOL) after PE. Improvement of patients’ satisfaction by PSQ after nurse-led education was 0.4±0.4 and it was higher than 0.3±0.5 after MD-led education, but it was not statistically different (p=0.25). Conclusion. PE for RA patients improved patients’ satisfaction and QOL. Nurse-led education showed comparable improvement in patients’ satisfaction with MD-led education. (J Rheum Dis 2016;23:109-117)

Objective: Assessment of health-related quality of life in patients with rheumatoid arthritis (RA) has become important in health research. Health economists have used linear regression equations to mathematically transform changes in HAQ scores into EQ5D data, which can be used to calculate quality adjusted life years (QALYs). We aimed to examine whether a given approach is justified. Methods: A total of 223 patients with RA were recruited from the Hospital for Rheumatic Diseases at Hanyang University. They completed the HAQ and EQ5D and a correlation analysis was performed between the two instruments. We compared HAQ and EQ5D score changes for patients who completed the EQ5D and HAQ at first and second visits (n=159). Predicted EQ5D was estimated from the HAQ using the calculating method of Bansnack et al. The mean difference between the predicted EQ5D from the HAQ and observed health utility score at the first visit and change during the study were tested by the paired t-test. Results: In the cross-sectional study, EQ5D scores were moderately inversely correlated with HAQ (r=-0.716, p<0.001). However, the predicted EQ5D from the HAQ was significantly different from the observed EQ5D (p=0.001; 95% confidence interval [CI] 0.020∼0.079). The change in EQ5D was also inversely correlated with the change in the HAQ (r=-0.615, p<0.001), and change in the predicted EQ5D scores corresponded well with changes in observed health utility scores (p=0.155; 95% CI (-0.0873∼0.0140). Conclusion: Changes in predicted EQ5D corresponded with observer changes in EQ5D, suggesting that it may be better to use predicted EQ5D form HAQ to identify change in the quality of life.

Rheumatic diseases are diverse groups characterized by a variety of clinical manifestations and diseasecourses in each patient. The best way to understand the course and prognosis of these patients is through observational cohort studies. The cohort studies also provide an opportunity to describe diseases outcomes including therapeutic responses and evaluate the effectiveness and safety of new therapy. It helps to understand disease pathogenesis and provide insight into the mechanisms of disease progression. The strengths of a cohort study are that it has a large number of patients over a long period of time. The patients in cohorts should be representative of the patients with diseases. Thoughtful study design and planning before establishment of cohorts will lead successful follow-up and increase data quality. The observation process must be clearly defined and followed according to the standard protocols.We reviewed numerous cohorts in rheumatic diseases and suggested the points to be considered for cohorts establishments.
