Objective: Heart rate variability (HRV) reflects the regulation of the autonomic nervous system. Panic disorder is highly associated with autonomic dysfunction, and is often accompanied by depression. The aim of this study is to determine the association between depression and HRV indices in patients with panic disorder. Methods: A total of 110 outpatients diagnosed with panic disorder participated in this study. The medical records of patients with panic disorder who visited the outpatient clinic of Konkuk University Hospital between December 2018 and March 2020 were retrospectively reviewed. Measurements used in this study include the Panic Disorder Severity Scale-Self Report, Beck Depression Inventory (BDI-II), Insomnia Severity Index, and HRV. Patients were divided into depressive and non-depressive groups based on their BDI-II scores. The association between HRV indices and depressive symptoms was statistically analyzed. Results: The low frequency/high frequency (LF/HF) ratio was reduced in patients with depression (mean = −0.095, p = 0.004 in the above moderate depressive group, mean = −0.120, p = 0.020 in the severe depressive group). Significant correlations were found between depressive symptoms and standard deviation of NN interval (SDNN) (ms) (−0.19, p = 0.044), very low frequency (VLF) (ms2/Hz) (−0.22, p = 0.021), LF (−0.25, p = 0.008), HF (−0.19, p = 0.043), and LF/HF (−0.25, p = 0.009). Multiple linear regression analysis showed that BDI predicted SDNN (ms), VLF (ms2/Hz), LF, HF, and LF/HF. Conclusion: We confirmed that the LF/HF ratio decreases when depression is accompanied by panic disorder. HRV indices may be useful markers for detecting depressive symptoms in patients with panic disorder.

Network Analysis Revealed the Role of Helplessness as a Central Feature Among Late-Life Depressive Symptoms in Patients With Mild Cognitive Impairment and Early Stage Dementia

Sumin Hong,Eun Jung Cha,Yeonsil Moon,Seung-Ho Ryu,Hong Jun Jeon 대한신경정신의학회 2024 PSYCHIATRY INVESTIGATION Vol.21 No.4

Objective It has been reported that depressive symptoms in older adults are different from those in younger adults, especially when accompanied by cognitive decline. However, few studies have investigated the network structure of depressive symptoms in this population.Methods The participants consisted of 627 older adults (>60 yr) who were diagnosed with mild cognitive impairment (MCI) or early stage dementia. Among them, 36.7% were male and the mean age was 76.20±7.71 years. The Korean form of Geriatric Depression Scale (KGDS) was used to evaluate their depressive symptoms and network analyses were performed using bootnet R-package to identify the central features among depressive symptoms.Results Of all the KGDS items, we found that KGDS 2 (often feel helpless) had the highest node strength followed by KGDS 21 (in good spirits), KGDS 14 (not confident at all), and KGDS 15 (cheerful and happy). In terms of node betweenness, KGDS 2 also showed the highest value. The edge weights of edges connected to node KGDS 2 were strongest in KGDS 3 (restless and fidgety) and KGDS 28 (easily get tired).Conclusion In this study, we presented which symptoms are central among the elderly with MCI and early stage dementia. This result not only increases the understanding of depressive symptoms in this group but would also help determine target symptoms in the treatment program.

The Mediating Effect of Insomnia on the Relationship between Panic Symptoms and Depression in Patients with Panic Disorder

Sumin Hong,Seolmin Kim,Doo-Heum Park,Seung-Ho Ryu,Jee Hyun Ha,Hong Jun Jeon 대한의학회 2021 Journal of Korean medical science Vol.36 No.9

Background: This study aimed to determine if sleep disturbances may mediate the relationship between panic symptoms and depression in patients with panic disorder (PD). Methods: Electronic medical records were retrospectively reviewed for 110 consecutive patients with diagnosed PD in an outpatient clinic between October 2018 and December 2019. Measurements include the PD Severity Scale, Beck Depression Inventory-II (BDI-II) and Insomnia Severity Index (ISI). Statistical analyses were performed to assess any potential relationship between PD, insomnia and depression. Results: Of the PD patients, 88 (80%) and 89 (80.9%) had comorbid depression (BDI-II ≥ 14) and insomnia (Korean version of the ISI ≥ 8), respectively. In a mediation model using insomnia as the mediating variable, the total effect of panic symptom severity on depression was significant (t = 7.23, P < 0.001). There were significant effects of panic symptoms on insomnia (t = 4.62, P < 0.001) and of insomnia on depression (t = 6.69, P < 0.001). The main effect of panic symptom severity on depression was also significant, after controlling for the effect of insomnia (t = 5.10, P < 0.001), suggesting partial mediation. Conclusion: Both depressive symptoms and insomnia are common in patients with PD and depression was partially mediated by insomnia in these patients. These results suggest that an intervention for insomnia in patients with PD might help prevent the development of depression.

사유로서의 도덕: 아렌트의 도덕관

홍수민(Sumin Hong) 한국도덕교육학회 2021 道德敎育硏究 Vol.33 No.4

이 글의 목적은 사유를 기반으로 하는 아렌트의 도덕관을 설명하는 데 있다. 도덕에관한 아렌트의 견해는 이론적 논의의 지평에서 출발한 것이 아니라, 그가 목도한 20세기의 정치적 비극을 철저히 이해하고 반성하고자 함에서 비롯된 것이다. 자신의 문제의식을 바탕으로 일련의 도덕철학적 탐구를 진행하면서, 그는 특히 고대 희랍의 지혜와도덕적 통찰에 주목하였으며, 이를 통해 ‘사유’(Thinking)라는 인간의 정신활동에 도덕을 정초하고자 하였다. 따라서 본 논문에서는 사유의 속성을 ‘의미탐구’, ‘내적 대화’, 그리고 ‘고독’의 세 가지 측면에서 설명하고, 그것의 도덕적 함의를 드러내보고자 하였다. 아렌트의 사유는우리의 삶과 관련된 모든 것들의 의미를 검토하고 성찰하는 것으로, 지식이나 실제적목적에 봉사하는 활동이 아니다. 또한 그는 사유를 나와 나 자신의 소리 없는 대화로규정하였는데, 이는 사유가 나 자신을 대면하는 자기-의식적인 활동임을 의미한다. 마지막으로 고독은 사유할 때의 인간의 존재방식으로, 사유하는 나는 외부의 활동을 중지하고, 자기 자신을 대면한다. 아렌트에 의하면, 이 끊임없이 반복되는 사유의 과정에서인간은 비로소 그 자신을 자아를 갖춘 하나의 온전한 인격체로 형성하며, 이와 같이 형성된 개인의 인격은 곧 그의 도덕성과 일치한다. 이런 점들을 종합해볼 때, 한 인간의사유 활동은 그의 도덕성과 필연적 관련성을 지닌다. 사유는 그 자체로 도덕적 숙고이며, 다른 모든 인간 활동의 바탕을 이루는 것이다. The purpose of this article is to discuss Hannah Arendt s Ethics which is based on ‘Thinking’. Her view on morality did not start from the angle of theoretical discussion, but from her thorough understanding and reflection on the political tragedy of the 20th century. Through conducting a series of moral philosophical research, she especially focused on the wisdom and moral insights of ancient Greece, and tried to establish morality in the human mental activity of thinking. This can be viewed as a modern reinterpretation of the Socratic Morality. In this regard, this article explores the attributes of thinking in three aspects; ‘quest for meaning , silent dialogue with myself , and solitude and discuss the moral implications from them. According to Arendt, Thinking is not about a knowledge or problem-solving but a process to examine and reflect on the meaning of everything related in our lives. In addition, she defined thinking as the silent dialogue of myself with myself, it means that thinking is a self-conscious activity to face and be with myself. Lastly, solitude is a mode of human existence through thinking which is distinguished from other modes of being alone, loneliness or isolation’. In solitude, a man have to stop other activity and face himself. In this process of thought, a mere human explicitly constitute himself a specifically person; his personality coincides with his morality. Through this moral effect, Arendt viewed that thinking could be a necessary condition to prevent men from evil-doing.

인공지능 스피커를 활용한 언어교육에서 교수자의 스캐폴딩 전략 개발

홍수민 ( Sumin Hong ),임철일 ( Cheolil Lim ) 한국교육공학회 2021 교육공학연구 Vol.37 No.2

인공지능은 사회 전반에 걸쳐 영향을 주고 있으며, 교육의 혁신적 변화를 일으키고 있다. 전통적으로 새롭게 등장한 기술은 교수 매체로 활용되었지만, 인공지능 기술은 수업의 필수 요소로 통합되고 있다. 이제 인공지능은 부분적이지만 교수자의 역할을 대신하기에 이르렀고, 교수자의 역할 변화를 요구하고 있다. 이에 본 연구에서는 인공지능 스피커를 활용한 언어교육에서 교수자의 구체적인 역할, 즉 스캐폴딩 전략 개발을 목적으로 설계·개발 연구방법을 통해 스캐폴딩 전략을 개발하고 타당성을 검토하였다. 선행문헌 분석과 전문가 면담을 통해 초기 스캐폴딩 전략을 도출하고, 세 차례의 전문가 검토를 통한 내적 타당성 검토와 현장 평가를 통한 외적 타당성 검토를 거쳐 인공지능 스피커를 활용한 언어 수업에서 교수자의 스캐폴딩 전략을 최종 개발하였다. 연구결과로 교수자의 스캐폴딩 전략은 인지적, 정의적, 기술적 전략으로 구분하였으며, 각각의 전략과 지침을 제시하였다. 인지적 스캐폴딩 전략은 학습 내용에 대한 지원, 정의적 스캐폴딩 전략은 학습 과정을 촉진할 수 있는 정서적 요인에 대한 지원, 기술적 스캐폴딩 전략은 학습 과정에서 테크놀로지의 효과적 사용에 대한 지원이다. 인지적 스캐폴딩 전략은 발화 시범 등 10개의 전략과 24개의 지침, 정의적 스캐폴딩 전략은 인공지능 스피커의 의인화 전략 등 7개 전략과 16개의 지침, 기술적 스캐폴딩 전략은 인공지능 스피커의 기술적 원리 설명 등 4개의 전략과 11개 지침으로 구성된다. Artificial intelligence affects society as a whole and is inducing innovation in education as well as other fields. Although new technological media have been incorporated in teaching, artificial intelligence technology is being integrated as an indispensable part of the classroom. As artificial intelligence has begun to replace teachers at least in part, a change in the role of teachers is called for. Accordingly, this study aims to develop a specific role for teachers in language education using artificial intelligence speakers. The study’s focus is to develop a strategy and to examine its validity through literature review and expert interview. The final scaffolding strategy for teachers in artificial intelligence speaker-based language classes was derived from three expert reviews followed by on-site assessment to examine its internal and external validity. Accordingly, teacher's scaffolding strategies were classified into three categories: cognitive, affective, and technical. Strategies, guidelines, examples, and explanations were then provided for each type. Cognitive scaffolding refers to content- related support, affective scaffolding to an emotional support that can promote learning, and technical scaffolding to a technological support in the learning process. Cognitive scaffolding consists of 10 strategies including expression demonstrations and 24 guidelines. Affective scaffolding consists of seven strategies including personification of the artificial intelligence speaker and 16 guidelines. Technical scaffolding consists of four strategies including explanations of technological principles of artificial intelligence speakers and 11 guidelines.

포자모형을 적용한 교권보호 정책의 정책형성과정 분석 : 학생인권 정책과의 관계를 중심으로

홍수민(Sumin Hong),이승호(Seung-ho Lee) 한국교육학회 2020 敎育學硏究 Vol.58 No.3

우리나라에서 ‘교권’에 관한 논의는 제한적으로 이루어져 왔다. 교권에 대한 현재의 논의는 교권의 가장 소극적인 차원, 교사의 인권을 보호하거나 교육활동 침해에 대한 법적인 방지 조치를 다루는 수준에 머물러 있으며, 교권을 바탕으로 우리 교육이 어떻게 이루어져야 하는지에 대한 실제적이고 적극적인 탐색이 되지 못하고 있다. 따라서 본 연구에서는 현재 교권과 관련하여 가장 활발하게 논의되는 ‘교권보호’라는 의제와 관련 정책이 설정되는 과정을 분석하며 그 이유를 밝혀보고자하였다. 특히 정책형성과정 모형 중 ‘포자모형’을 통해 교권보호 정책의 형성과정을 분석함으로써교권보호의 의제 설정 과정을 살피고 교권보호 정책이 학생인권 정책과 가지는 연관성과 이를 통한 변화의 과정을 분석하였다. 포자모형은 민주주의 사회에서 ‘상이하고 작은 힘을 가진 개인들’이 ‘하나의 영향력’을 행사하는과정을 설명하기에 적합한 모델이다. 따라서 포자모형을 통해 교권과 관련된 의제가 형성되어가는과정을 분석하는 것은 교권 관련 정책으로서 제시되는 교원지위법이나 교권보호조례와 같은 정책형성의 원인과 과정을 더 세밀하게 드러내어준다. 본 연구에서는 이와 같은 분석의 결과 현재 우리나라에서 시도되는 제한적인 교권에 대한 논의와 정책의 원인은 바로, 교권이 교육과 교사의 본질적이고 적극적 역할을 수반하는 개념임에도 불구하고 그에 대한 의제설정과정이 ‘학생인권조례’와같은 학생인권 정책에 대한 반동으로 이루어졌기 때문임을 드러내고자 하였다. Discussions on ‘teachers’ rights have been limited in our country. The current discussion of teacher’s rights remains at the most passive level, focused on the legal measure to protect teachers human rights or infringement of educational activities and lacks a practical and active search on how education should be developed based on teacher s rights. In this regard, this study highlights ‘protection of teachers’ rights and the relevant policy making process focusing on the reason of the current passive discussion regarding teacher s rights. In particular, it studies the agenda building process for the protection of teachers rights by analyzing the relevant policy making process applying the Spore Model and analyzes the connection between the student s human rights policies and the teacher s rights protection policies. The spore model is suitable for explaining the process how individuals exercise their influence in a democratic society. Therefore, analyzing the agenda building process regarding teachers rights through a spore model further reveals the causes and the process of the policy making such as the Teachers Status Act and the Teacher s Rights Protection Ordinance. In this light, this study addresses the reason for the current limited discussion on teacher s rights in the Korean society, suggesting that even though teacher s rights entails active and fundamental role of education and teachers, the agenda was built as a reaction to the student s human rights policies such as Students’ Human Rights Ordinance .
