Jieun Kwon,Ken Nah 대한인간공학회 2014 大韓人間工學會誌 Vol.33 No.3

Objective: The goal of this research is to develop new user behavior model using user motion analysis with microscopic perspective for attracting user"s participation in interactive space. Background: The interactive space is "human"s place", which is made up of complex elements of digital virtual space and traditional analog and physical environment based on human-computer interaction system. Human behavior has changed in it at the same time. If the user couldn"t make participation in interaction, the purpose of the system is not met, which reduces its effect. Therefore, we need to focus on interactive space that is potential future direction from a new point of view. Method: For this research, we would discuss and study fields of interactive space; (1) finding definition of interactive space and studying background of theory about it. (2) providing base of user behavior model with study of user"s context that is to be user information and motion. (3) examining user motion, classify basic motion type and making user participation behavior model in phases. Results: Through this process, user"s basic twenty motions which are systematized are taken as a standard for analysis of interaction process and participation in interactive space. Then, ‘NK-I5 (I Five)" model is developed for user participation types in interactive space. There are five phases of user participation behavior: Imperception, Interest, Involvement, Immersion, and Influence. In this analysis, three indicators which are time, motion types, and user relationship are found to be related to participation. Conclusion: The capabilities and limitation of this research is discussed to attract user participation. This paper focuses especially on contribution of design to lead user"s participation in interactive system and expectation to help adapt to user centered design of various interactive space with new aspect of user behavior research. Application: The results of the ‘NK-I5 (I Five)" model might help to realize successful interactive space based on user centered design.

Jieun Kwon,Yeun Ho Kim,Tae Sung Yeom,Joo Han Oh 대한견주관절의학회 2015 대한견주관절학회지 Vol.18 No.1

Background: Repair of superior labral anterior to posterior (SLAP) lesion in patients older than 40 years is controversial. The purpose of this study was to evaluate clinical outcomes of arthroscopic repair of SLAP lesions between younger and older patient groups. Methods: We reviewed 50 patients with isolated type II SLAP lesions who underwent arthroscopic repair. Patients were divided into 2 groups: group 1 included 20 patients aged <40 years, and group 2 included 30 patients aged ≥40 years. Functional outcome at the final follow-up was assessed using a visual analog scale for pain and satisfaction, American Shoulder and Elbow Surgeons form, Constant score, University of California at Los Angeles score, and periodic change in range of motion (ROM). Anatomical outcome was evaluated using computed tomography (CT) arthrography at least 1 year after surgery. Results: No significant differences in functional scores or postoperative ROM were observed between the 2 groups. In group 2, later recovery of ROM (forward flexion, p=0.025; internal rotation, p=0.034) and lower satisfaction score (p=0.06) were observed for atraumatic patients (n=16) compared to patients with traumatic injury (n=14). Fifteen patients in group 1 (15/17, 88%) and 21 patients in group 2 (21/26, 81%) demonstrated a healed labrum on postoperative CT arthrography, and this difference was not significant. Conclusions: The results of this study suggest that arthroscopic repair of type II SLAP lesions can yield good functional and anatomical outcomes regardless of age, if patient selection is adequate. However, the delay in ROM recovery and lower satisfaction, particularly in older patients without traumatic injury, should be considered.

Jieun Kwon 대한전자공학회 2020 IEIE Transactions on Smart Processing & Computing Vol.9 No.3

Recently, technologies for expressing or recognizing emotion from facial expressions in digital displays, such as those found on smart dolls and robots, have been advancing. Among such facial expressions, the eyes can express detailed emotions through fine movements and reactions. The purpose of this study is to extract the elements for expressions of emotion via digital media used for smart-dolls’ eyes, and to develop guidelines for creating such expressions of emotion. Extraction of factors for the expression of emotion along with a suitability verification process were conducted to develop suitable eye content for smart dolls through expert focus group interviews, surveys, and statistical analysis. As a result, four elements for the expression emotion with the eyes (eye shape, gaze, iris size, and effect) were derived, and 13 emotional expression guidelines were developed accordingly. The findings of this study are expected to play an important role as an effective technology tool for communication of emotions when developing facial expression systems using the digital displays that continuously appear.

앱북(App Book)으로의 매체 전환을 위한 퍼놀로지(Funology)에 관한 연구

권지은(Kwon, Jieun),김보영(Kim, Boyoung) 한국만화애니메이션학회 2013 만화애니메이션연구 Vol.- No.30

전통적인 인쇄매체의 종이책이 최근 디지털 기술의 발달로 인해 스마트기기에서도 전자책이라는 매체로도 확장 되고 있다. 특히 애플리케이션(Application) 형태의 콘텐츠로 제공되는 앱북(App Book)은 책이 가지고 있는 기본적인 정보제공과 교육, 감성전달 목적 이외에 멀티미디어 기술을 활용한 재미 요소를 부가하여 몰입도를 배가 시키고 체험적 효과를 증가시키고 있다. 기존에 이미 검증받은 고퀄리티콘텐츠를 애플리케이션 매체로 전환하는데 있어서 그 효과를 높이기 위해 다양한 시도들이 이루어지고 있다. 본 논문은 앱북으로의 매체 전환에 있어서 디지털 기술과 재미 요소가 융합된 퍼놀로지(Funology)가 어떻게 활용되고 사용자에게 어떠한 효과를 제공하는지에 대해 사례를 분석하여 앞으로의 앱북 콘텐츠 개발에 가이드를 제공하고 활용될 수 있도록 하고자 한다. 본 논문에서는 첫째, 문헌조사를 통해 퍼놀로지에 대한 개념과 요소들을 살펴보고 분석할 수 있는 기준의 토대를 마련한다. 둘째, 원작 "무, 바, 라라라!(Moo, Baa, La La La!)’ 그림책을 아이패드(iPad)용 애플리케이션으로 전환한 앱북을 선정하여 퍼놀로지 요소에 따라 분석하였다. 셋째, 분석한 요소들이 실제로 인쇄매체의 종이책과 비교하여 퍼놀로지의 활용과 효과를 확인하기 위해 심층인터뷰인 FGI(Focus Group Interview)를 실행하였다. 그 결과 사운드를 활용한 감각적 퍼놀로지에 대한 감성적 효과가 높았으며 즉각적이고 직관적인 모션과 변화에 따른 인터랙션에 의한 퍼놀로지 요소를 선호하고 있었다. 또한 기존의 오리지널 책에서 강조되던 유희 자체를 위한 퍼놀로지 요소는 다른 관점에서의 즐거운 감성으로 유도하고 있어 책의 콘텐츠 내용과 정보 보다는 게임적 성향의 인터랙션 자체에 더욱 치중되어 체험하고 있음을 알 수 있었다. 이러한 분석과 인터뷰 결과는 지속적으로 개발되고 있는 앱북 개발에 있어서 본래 책이라는 매체가 가지고 있는 콘텐츠의 장점을 살리면서 애플리케이션의 퍼놀로지 요소의 특징을 부각시킬 수 있는 매체전환 방법에 대한 활용 가능성을 기대해 본다. Recently, traditional books based on printing on the paper have expanded to e-book media in smart device because of developing digital technology. Especially, app book applied application makes users" experience increase and provides immersion to them, because it allows them basically delivering information, educational effect and fun elements with multimedia technology. There are various experimental trials to make enhance effect of reformatting for application media. The purpose of this study is to analyze reformatting effect for app book with funology which is convergence of digital technology and a fun. Then this article would provide design guide and be applied to new application contents. For this research, the first of all, we would discuss concept and elements of funology by publication including thesis, articles, and books. Secondly, this article will be focused on "Moo, Baa, La La La!" which is reformatting application for iPad to analyze type of funology. Thirdly, we would make sure that app book makes users get emotional effect comparing original book by FGI(Focus Group Interview). In conclusion, sensitive funology used the sound allows user emotional effect and they prefer to intuitive and immediate motion and response of interactive funology. In other way, funology of fun in itself which is strong concept in original book diminishes in app book. Then users concentrate interactive factors like game structure. This results make that app books could be created by strength of original contents and advantage of funology. Therefore this makes us expect the possibility of reformatting effect with funology and we need to discuss the points of issue that there are considerations and limitations to successful app book for users.
