Objective This cross-cultural study aims to examine the psychometric properties of the Social Responsiveness Scale (SRS) and to determine the best-estimate-cut-off scores for the diagnosis of autism spectrum disorder (ASD) in Korean preschool children.Methods A total of 563 children was recruited from multiple sources, including Seoul National University Bundang Hospital. Participants were assessed by a multidisciplinary research team using multiple diagnostic tools based on DSM-5 diagnostic criteria. Discriminative validity was tested by comparing the difference in SRS scores between ASD and non-ASD groups. Convergent validity was tested by examining correlations between SRS scores with other diagnostic instruments. A receiver operation characteristic curve analysis was conducted to test the sensitivity and specificity of SRS and to determine the best-estimate-cut-off scores for screening ASD in Korean preschool children.Results There were significant differences in the total SRS scores between the ASD (n=242) and non-ASD group (n=321) (p<0.01, 95% confidence interval [CI]: 14.08–17.24). The differences were significant even after adjusting for age. SRS scores were significantly correlated with other prescreening diagnostic tools for ASD. The best-estimate cut-off score to screen ASD was 55 (area under curve=0.88, sensitivity 78.1%, specificity 86.6%).Conclusion The SRS is a valid and reliable instrument to screen and aid in the diagnosis of ASD in Korean preschool children. The adjusted cut-off scores, notably lower than in the original U.S. version, may yield a more accurate diagnosis by reflecting transcultural differences.

천지영(Jeeyoung Chun),김성길(Seonggil Kim) 한국배움학회 2011 배움학 연구 Vol.3 No.1

이 연구는 대학 수업의 주체인 성인들의 사회적응력을 높이기 위하여 사회 변화에 맞는 수업형태가 구현될 필요성이 높아짐에 따라 대학 수업형태를 시나리오 플래닝에 기반하여 예측해보는 동시에, 이렇게 예측된 수업형태에 함축되어 있는 가치를 배움학의 관점에서 고찰해 봄으로써 미래 대학 수업에서 배움학의 의미를 살펴보는데 목적이 있다. 시나리오 플래닝에 따라 미래 수업형태를 구분하면, 시나리오1은 전통적 수업형태, 시나리오2는 크로마키 수업형태, 시나리오3은 코스모폴리탄 수업형태, 시나리오4는 개방형 모둠 수업형태로 나눌 수 있다. 이들 시나리오들을 배움학의 관점에서 해석하면, 전통적 수업형태는 공동학습의 의미를 지니고, 크로마키 수업형태는 쓰임새학습 중심 수업형태라 할 수 있다. 코스코폴리탄 수업형태는 공동학습을 통한 쓰임새학습을, 개방형 모둠 수업형태는 자기주도학습을 기반으로 한 공동학습의 성격을 갖는다. This study explores possible forms of university classes in the future based on scenario planning. Also, this study analyzes the meaning of a class from the perspective of the science of erudition. First of all, four different scenarios have been identified. Scenario 1 is the traditional form of class. Scenario 2 is a chromakey style form of class. Scenario 3 is a cosmopolitan style form of class. Scenario 4 is conducted as a small group meeting in a virtual space through an open network. Next, the meaning of a class is examined from the perspective of the science of erudition. The Scenario 1 class has meaning as a collaborative learning forum. The class from Scenario 2 is a practical learning forum. In Scenario 3, the class is a co-learning practical learning forum. Scenario 4 class is a collaborative learning forum based on self-directed learning. Through this research the following conclusions can be drawn. This study proves that the science of erudition can be applied to a practical alternative through analysis from the perspective of the science of erudition.

정보 폭증으로 인한 정보 필터링 어려움을 해결하기 위한 추천 시스템의 중요성이 강조되고 있다. 특히 취업 구직자가 어떤 기업에 지원해야 하는지 혼란스러워하는 문제가 증가하고 있다. 이에 본 연구에서는 교육 기관에 등록된 학생 데이터를 활용하여 각 개인에게 적합한 기업을 추천해주는 맞춤형 기업 추천 시스템을 제안하고자 한다. 다양한 유사도 함수를 적용하여 비교한 결과, 코사인 유사도(Cosine similarity)를 활용한 추천 시스템이 가장 높은 정확도를 보였으며, 이러한 연구는 취업 관련 결정을 지원하는 데 중요한 역할을 할 것으로 기대된다.

Bridging Oriented Copper Nanowire–Graphene Composites for Solution-Processable, Annealing-Free, and Air-Stable Flexible Electrodes

Zhang, Wang,Yin, Zhenxing,Chun, Alvin,Yoo, Jeeyoung,Kim, Youn Sang,Piao, Yuanzhe American Chemical Society 2016 ACS APPLIED MATERIALS & INTERFACES Vol.8 No.3

<P>One-dimensional flexible Metallic nanowires (NWs) are of considerable interest for next-generation wearable devices. The unavoidable challenge for a wearable electrode is the assurance of high conductivity, flexibility, and durability with economically feasible materials and simple manufacturing processes. Here, we use a straightforward solvothermal method to prepare a flexible conductive material that contains reduced graphene oxide (RGO) nanosheets bridging oriented copper NWs. The GO-assistance route can successfully meet the criteria listed above and help the composite films maintain high conductivity and durable flexibility without any extra treatment, such as annealing or acid processes. The composite film exhibits a high electrical performance (0.808 Omega.sq(-1)) without considerable change over 30 days under ambient conditions. Moreover, the Cu NW-RGO composites can be deposited on polyester cloth as a lightweight wearable electrode with high durability and simple processability and are very promising for a wide variety of electronic devices.</P>

Kyomin Choi,Ohyun Kwon,Bum Chun Suh,Jeeyoung Oh,Sungkun Cho,Eunhee Sohn,In Soo Joo 대한신경과학회 2023 Journal of Clinical Neurology Vol.19 No.3

Background and Purpose The description of pain is the most-important indicator leading to the adequate treatment of patients with neuropathic pain (NeP). The purpose of this study was to identify and characterize the unique features of Korean verbal descriptions in patients with peripheral NeP. Methods This study included 400 patients (167 males and 233 females) and their 1,387 paindescription responses. Patients with peripheral NeP freely described their symptoms in Korean. Collected verbal descriptions were grouped according to terminologies with similar meanings. Participants completed validated patient-reported outcome scales including the neuropathic pain symptom inventory (NPSI) and painDETECT questionnaire (PD-Q). The frequencies of each verbal pain descriptor were compared between the NPSI and PD-Q scores. Results ‘Jeorim’ (tingling) was the most common among 17 types of organized verbal pain descriptors, and the ‘Sirim’ (cold) symptom had a significantly higher rate of use in the 2 highseverity groups when participants were classified by their total scores on the NPSI and PD-Q. Conclusions Korean verbal NeP descriptors were significantly diverse. The Jeorim (tingling) and Sirim (cold) descriptors can be utilized in evaluations of Korean patients with NeP.

Objective This study aimed to identify the factors affecting posttraumatic stress disorder (PTSD) symptom remission prospectively through a 1-year follow-up of sexual assault (SA) victims.Methods A total 65 female SA victims who visited the crisis intervention center were included. Self-administered questionnaires regarding PTSD symptoms and PTSD related prognostic factors were conducted at both recruitment (T1) and 1 year after recruitment (T2). The multivariate analyses were used to determine the significant predictors of PTSD remission/non-remission state 1 year after SA.Results In logistic regression analysis, both anxiety and secondary victimization were identified as significant factors explaining the results on PTSD remission/non-remission state at T2 (Beck’s Anxiety Inventory [BAI], p=0.003; Secondary Victimization Questionnaire, p=0.024). In a linear mixed analysis, both depression and anxiety were found to be significant variables leading to changes in Posttraumatic Diagnostic Scale for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition from T1 to T2 (BAI, p<0.001; Center for Epidemiological Studies Depression Scale, p<0.001).Conclusion Depression, anxiety symptoms, and secondary victimization after SA were associated with PTSD symptom non-remission 1 year after SA.

Kim, Jong Kuk,Kim, Byung-Jo,Shin, Ha Young,Shin, Kyong Jin,Nam, Tai-Seung,Oh, Jeeyoung,Suh, Bum Chun,Yoon, Byeol-A,Park, Hwan Tae,Huh, So-Young,Oh, Seong-Il,Bae, Jong Seok Ovid Technologies (Wolters Kluwer) - American Acad 2016 Neurology Vol.86 No.8

<P>Objective: To categorize a syndrome manifesting as prominent acute bulbar palsy (ABP) without limb motor weakness as a variant form of Guillain-Barre syndrome (GBS) and differentiate it from Miller Fisher syndrome (MFS) and pharyngeal-cervical-brachial (PCB) variants. Methods: We analyzed cases of ABP without limb motor weakness based on a dataset containing clinical information and the results of antiganglioside antibodies assays for acute immune-mediated neuropathies. Results: Eleven cases with an age at onset ranging from 18 to 65 years (mean 33.8 years) were identified as ABP-plus syndrome. All of the enrolled cases manifested with ABP as the predominant symptom, and with no limb weakness. The following features accompanied ABP in order of decreasing frequency: ophthalmoplegia (n = 9, 82%), ataxia (n = 9, 82%), and facial palsy (n = 6, 55%). An enzyme-linked immunosorbent assay study disclosed that immunoglobulin G (IgG) anti-GT1a antibodies were the most frequent (n = 11), followed by IgG anti-GQ1b antibodies (n = 6). Conclusions: We propose that ABP-plus syndrome without neck or limb weakness is a variant of GBS that is distinct from the MFS and PCB variants. The presence of IgG anti-GT1a antibodies can explain the relationships between the distinct clinical characteristics and the underlying pathomechanisms.</P>
