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.

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.

Objectives In 2015, the Institute of Korean Medicine Education & Evaluation undertook a study to develop a competency model for Doctors of Korean medicine, with the aim of transitioning the educational system of Korean medical colleges to a competency-based approach. Anticipating future societal changes, the research identifies educational needs for core competencies in Korean medicine, intending to enhance a competency-based curriculum for prospective doctors. Methods The study involved a survey of 44 students in Korean traditional medicine to investigate the importance and current implementation of core competencies. It utilized the Borich Needs Assessment and The Locus for Focus model to analyze the educational needs. Additionally, a survey was conducted to assess the competencies needed for traditional Korean medicine doctors in future. Results Results highlighted the highest educational needs in ‘Participating in Developing Policies for Public Health,’ ‘Finance & Human Resources Management,’ and ‘Manage Medications & Supplements.’ Conversely, lower needs were observed for ‘Participating in Public Health Events Locally & Nationally’ and ‘Learning & Research Activities.’ Essential competencies for future Korean medicine doctors included utilizing electronic medical records, understanding telemedicine technology, and proficiency in artificial intelligence and big data analysis. Conclusions The results showed a higher importance than implementation for all competencies, highlighting the need to review the current educational curriculum. Specifically, there is a need to cultivate competencies in traditional Korean medicine related to law, policy, and system involvement, and to enhance management skills as practitioners. The study also underscored the necessity of incorporating digital technology competencies for future Korean medicine doctors.The findings underscore the necessity for a curriculum redesign.

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 .
