Objectives To evaluate the evidence supporting the effectiveness of acupuncture for facet joint syndrome. Methods We conducted search across 9 electronic databases (PubMed, EMBASE, Cochrane CENTRAL (CENTRAL), KoreaMed, Kmbase, Koreanstudies Information Service System (KISS), ScienceOn, China National Knowledge Infrastructure (CNKI), and Wanfang) to find clinical trials that used acupuncture as treatment for facet joint syndrome. The methodological quality of randomized controlled clinical trials (RCTs) were assessed using the Cochrane Risk of Bias (RoB) tool, while non-randomized controlled clinical trials (nRCTs) were assessed using the Cochrane Risk of Bias Assessment tool for Non-randomized Study (RoBANS) tool. Results Nine RCTs and one nRCT met our inclusion criteria. Fire needle was more effective than medial branch block in terms of visual analogue scale (VAS) after 1 month (p=0.02). Also, Fire needle was more effective than Ibuprofen in terms of VAS and oswestry disability index (ODI) (p<0.05). However, in the rest of the study results, the intervention group did not show a statistically significant difference than the control group. Conclusions Although our review found encouraging but limited evidence of acupuncture for facet joint syndrome, most of the studies included in the analysis were evaluated as methodologically high risk of bias. From now on further well-designed RCTs should be encouraged. (J Korean Med Rehabil 2023; 33(1):13-29)

박물관 맥락에서의 로봇성격 설정의 중요성 연구

구지향,신동희 한국콘텐츠학회 2016 한국콘텐츠학회논문지 Vol.16 No.3

This study investigates human-robot interactions in a museum environment. Unlike robots in movies, robots in real life do not have ‘personality,’ but instead have a specific purpose and function. This research is primarily about the assignment of specific and appropriate personalities to robots in different contexts. Methods by which a definite personality can be imparted on a robot are discussed in this research. Previous research has addressed attempts to assign a robot personality based on the task context. However, the discussion of robot personality is incomplete. Therefore, we assumed that a robot's character was dependent on the characteristics of its location of use. We planned a 2x2 comparison of various robot personalities, i.e., introverted or extroverted paired with either a traditional museum or a process-oriented experiential experience. Based on Schmitt’s (1999) strategic experiential modules, experiential factors were derived for each set of conditions. To achieve the objectives of the research, theoretical and empirical research were conducted simultaneously. The software JMP 9 was used to verify the research model and hypotheses. 본 연구는 사람과 로봇의 인터랙션을 알아보는 것을 목적으로 한다. 영화 속에서 등장하는 로봇과는 달리 실생활에서 만나는 로봇에는 특정한 성격이 존재하지 않는다. 본 연구는 다른 맥락을 가지고 있는 공간에서 로봇의 성격을 어떤 식으로 매치하는 것이 효과적인가에 대해 논의하고 있다. 본 연구의 목적을 달성하기 위해 외향성, 내향성이라는 두 가지 성격의 유형을 구분하고 선행연구에 기반하여 전통적인 형태의 박물관, 과정 중심적인 박물관 유형 조건으로 피험자간 설계를 실시하였다. 연구 결과, 피험자들은 로봇의 성격만 보았을 때 체험요소에 유의미한 영향을 미치지 못한 것으로 나타났다. 반면 다른 맥락의 장소 조건에서는 사회 정체감 요소에서 유의미한 결과를 보였다. 또한 모든 조건에서의 인터랙션 효과는 유의미하게 영향을 미치는 것으로 나타났다. 흥미로운 사실은 사용자가 가장 선호하는 조건은 외향적 성격의 로봇과 과정 중심적인 박물관 유형이며, 사용자가 가장 선호하지 않는 조건은 외향적 성격의 로봇과 전통적 유형의 박물관이었다. 이러한 결과의 함의에 대해서는 본문에서 논의하고 있다. 통계 분석은 JMP 9을 사용하여 리서치 모델 및 가설을 검증 하였다.

어포던스(affordance)에 근거한 박물관 및 미술관 모바일 도슨트 어플리케이션 디자인 연구

구지향(Gu, Ji Hyang),김태양(Kim, Tae Yang),신동희(Shin, Dong Hee) 한국디지털디자인협의회 2014 디지털디자인학연구 Vol.14 No.3

ICT의 융합적 발달과 스마트폰의 급격한 확산은 박물관과 미술관에도 영향을 끼치고 있다. 모바일 도슨트 어플리케이션은 사용자와의 인터랙션을 통해 다양한 커뮤니케이션을 가능하게 해주고 인지적 부담을 덜어줄 것으로 보인다. 하지만 이러한 변화에 비해 모바일 도슨트어플리케이션에 관한 연구는 미흡한 실정이다. 본 연구에서는 3가지 모바일 도슨트를 중심으로 사용자가 각각의 어포던스를 평가해 봄으로써 사용자 참여를 증진 할 수 있는 어포던스 요인을 연구하고자 한다. Hartson이 제안한 어포던스 유형인 인지적, 물리적, 감각적, 기능적 어포던스를 기반으로 하였으며 연구 대상으로 선정한 3가지 어플리케이션을 중심으로 총 18명을 상대로 반 구조화 된 포커스 그룹 인터뷰를 진행 하였다. 그동안 미흡했던 모바일 도슨트 어플리케이션에 관한 연구를 어포던스 이론을 기반으로 포커스 그룹 인터뷰를 시행 하였고, 도출된 각 유형별 특징들을 적용해 모바일 도슨트 앱 인터페이스의 지향점을 제시해 보았다. Hartson의 어포던스 이론을 바탕으로 모바일 도슨트 디자인을 설계한다면 사용자의 경험에 적합한 대안이 될 수 있을 것이라 기대된다. ICT and the rapid diffusion of smart phone influences the design and management of museums and galleries. By means of wide spreading, Mobile Docent program would make it possible to communicate with users and reduce cognitive burden. Despite its importance, however, researches on Mobile Docent applications have been lacking significantly. In this light of scarce, the goal of this study is to identify the factors of affordance. This study assesses each affordance, following the ideas of three types of mobile docents. On the three selected applications of this research, 18 participants were interviewed in semi-structured focus group. The affordance theory is based on affordance type introduced by Hartson: cognitive, physical, sensory, and functional affordance. Focusing on the previous affordance theory on Mobile docent program, this study conducts a focus-group interview and observes the features of each type. Based on the findings of the study, it suggests the mobile docent application interface. To further this study on mobile docent design, the affordance theory by hartson will be helpful to develop a great alternative for user experience.

지향,김대용,지동범,최을수 한국임상수의학회 2009 한국임상수의학회지 Vol.26 No.6

A 5-year-old Pekinese dog was presented for evaluation of a back mass of 1 year duration. Fine needle aspiration cytology of the mass revealed numerous keratinocytes, and a lesser number of multinucleated giant cells along with a low number of spindle cells, which were suggestive of epidermal cyst or hair follicle tumor with secondary granulomatous inflammation. The mass was surgically removed and examined histologically. Microscopically there was partially encapsulated well-demarcated nodule in deep dermis and subcutis. The nodule consisted of central cyst and secondary cysts that were lined by a single or multiple layers of basaloid cells and squamous epitheliums with central laminated keratin. Multifocal aggregation of numerous macrophages and multinucleated giant cells were present. The final diagnosis was keratoacanthoma with granulomatous inflammation. The mass did not recur 5 months after surgery.

지향,최을수,방동하,김대용,황철용,윤화영,Jean-Sébastien Latouche 한국임상수의학회 2009 한국임상수의학회지 Vol.26 No.1

A 5-month-old intact female Siberian Husky dog was presented for evaluation of severely enlarged maxilla. Abnormalities in CBC, serum chemistry and urinalysis indicated purulent inflammation and renal failure. Cytologic examination of the swollen maxilla showed a mixed population of multinucleated giant cells and round to polygonal to spindle shaped cells either individualized or aggregated. Both type of cells showed moderate anisokaryosis, and anisocytosis, prominent nucleolus or multiple nucleoli, and coarse chromatin. On histopathology maxilla and turbinate were diffusely expanded and replaced by variably dense fibrous connective tissue, and the kidneys showed changes consistent with renal dysplasia. Based on these findings, the diagnosis of fibrous osteodystrophy due to renal dysplasia and fibrosis was made. Despite the supportive care, the dog continued to decline and was euthanized.

지향은,한인숙 한국교육방법학회 2024 교육방법연구 Vol.36 No.1

최근 교육용 인공 지능(AI) 기술이 빠르게 발전함에 따라 AI 챗봇의 교육적 활용에 대한 관심도 증가하고 있다. 본 연구에서는 언제 어디서든 사용이 가능한 모바일 기반 AI 챗봇의 사용이 학습자의 자기조절학습을 어떻게 지원할 수 있는지 탐색하기 위해, 영어를 외국어로 배우는 학습자의 자기조절학습을 도와주는 모바일 기반 챗봇을 설계, 개발하고 사용성 평가를 실시하였다. 미국과 한국 대학에 재학 중인 11명의 외국어 학습자들이 본 연구에 참여하였으며, 학습자들은 자신의 모바일 폰에 설치된 자기조절학습 챗봇을 활용하여 학습을 진행하였다. 4주에 걸친 학습 활동이 진행되는 동안 챗봇 상호작용 로그, 자기조절학습 사전 사후 설문 및 시스템 사용성 설문을 통해 데이터를 수집, 분석하였다. 연구 결과, 더 높은 수준의 자기조절학습 향상을 나타낸 학습자들이 챗봇과의 상호작용에서 더 포괄적이고 목표 지향적인 응답을 하였으며, 구체적인 학습 전략과 학습 과정에 대한 성찰적 사고를 보여주었다. 또한, 연구 참가자들은 전반적으로 모바일 기반 자기조절학습 챗봇 사용에 대해 긍정적으로 인식하였으며, 개방형 설문 문항에 대한 응답으로 자기조절학습 지원을 위한 챗봇 시스템의 개선점을 제안하였다. 이 연구 결과를 바탕으로 교육용 AI 챗봇을 활용한 자기주도학습 지원을 최적화하기 위한 향후 시스템 개발에 함의를 제공해줄 것으로 기대된다. Despite the rapid advancements in artificial intelligence (AI) technology in education, much remains to be learned on how self-regulated learning (SRL) is facilitated using mobile-based AI chatbots. To fill this gap, our study embarked on an exploratory investigation using a mobile-based chatbot designed to promote SRL behaviors among foreign language learners. The participants in the study were 11 adult foreign language learners from the United States and South Korea who interacted with the chatbot over a four-week duration on their mobile phones. Data were collected from chatbot interaction logs, pre- and post-SRL surveys, and a system usability survey. The findings revealed that learners with higher levels of SRL skill improvement interacted with more comprehensive and targeted responses, including specific learning strategies and reflective thoughts regarding their learning processes. We also found an overall positive perceived usability toward using a mobile-based SRL chatbot and a moderate correlation between perceived usability and SRL skill improvement. Open-ended survey data provided further suggestions on chatbot improvements when developing a chatbot system for scaffolding SRL processes. This work contributes to the burgeoning field of AI in education and provides directions for future research for optimizing chatbot-driven SRL interventions.
