Sumin Cha,Sookyoung Park,Jeonghyun Choi,Juhyung Park,Yunho Jin,Yonggeun Hong 한국콘텐츠학회(IJOC) 2019 International Journal of Contents Vol.15 No.3

This systematic review compared Korean and international researches on sensory integration therapy in patients with autism spectrum disorder (ASD). We targeted studies on sensory integration therapy for patients with ASD published from January 2000 through July 2016. Specifically, we analyzed the papers that used the phrase ‘sensory integration, autism’ as keywords. There were fewer Korean studies of sensory integration therapy, and the diversity of research topics were limited, focusing mainly on case studies. There was no difference between the internal/external validity of Korean and those of international studies targeting the clinical environment and patients. Further study of a variety of aspects of sensory integration therapy is needed to gain high internal/external validity.

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.

Passive House makes building more airtight and install lower U-value walls and windows. And most important purpose is to prevent the decline of indoor air quality. To improve indoor thermal comfort is the most important purpose. In this study, Europe’s Passive House design and ventilation standard is summarized.

Nd-저감/대체 희토류 영구자석 개발 동향

김수민(Sumin Kim),김태훈(Tae-Hoon Kim),차희령(Hee-Ryoung Cha),이정구(Jung-Goo Lee) 한국자기학회 2024 韓國磁氣學會誌 Vol.34 No.2

Nd-Fe-B 희토류 영구자석은 1983년 개발된 이후로 지금까지 상용자석 중 가장 높은 자기적 특성을 가지고 있어 수많은 산업 분야에서 핵심 소재로 적용되어 왔다. 특히 전기/하이브리드 자동차의 보급에 따른 전기모터의 소형화, 경량화, 고효율화에 대한 요구는 고특성 Nd-Fe-B 영구자석의 의존도를 더욱 증대시켰다. 하지만 2025년 네오디뮴(Nd)에 대한 수요가 공급을 넘어설 것으로 예측되고 있으며, 희토류 원소 보유국의 자원전략화 등으로 인한 희토류 공급/가격 리스크를 고려하였을 때 Nd-Fe-B 자석에 대한 의존도를 낮추는 방향으로 가야만 한다. 이에 대한 해결책으로 Nd 대신 세륨(Ce), 란타넘(La), 사마륨(Sm)과 같이 자원이 풍부하거나 시장에 과공급 되어있는 희토류 원소를 적극적으로 사용할 필요가 있다. 따라서 본 글에서는 Nd를 Ce, La 등의 경희토류 원소로 대체하는 ‘Nd-저감형 희토류 영구자석’과 Nd를 완전히 배제하는 Sm-Co, Sm-Fe(-N) 등과 같은 ‘Nd-free 희토류 영구자석’ 소재의 제조 기술과 연구 동향에 대해 다루고, 이 소재들의 상용자석으로서의 가능성을 살펴보고자 한다. Since the development of Nd-Fe-B based rare-earth permanent magnet in 1983, it has become indispensable materials in various industries, owing to their unparalleled magnetic properties among commercial magnets. Especially, the proliferation of electric/hybrid vehicles and demands for downsizing, lightweighting, and high efficiency of electric motors have further increased the reliance on high-performance Nd-Fe-B permanent magnets. However, it is predicted that the demand for neodymium (Nd) will surpass the supply by 2025, and considering the risks of rare earth supply/price due to the resource strategies of rare earth-rich countries, it is necessary to reduce the dependence on Nd-Fe-B permanent magnets. As a viable solution, active utilization of rare earth elements such as cerium (Ce), lanthanum (La), and samarium (Sm), which are abundant or oversupplied in the market, instead of Nd, is needed. Therefore, we will discuss the manufacturing technology and research trends of ‘Nd-reduced rare earth permanent magnets’ replacing Nd with Ce, La, and ‘Nd-free rare earth permanent magnets’ such as Sm-Co, Sm-Fe(-N), and explores their potential as commercial magnets.

Recently, the bio-healthcare market is enlarging worldwide due to various reasons such as the COVID-19 pandemic. Among them, biometric measurement and analysis technology are expected to bring about future technological innovation and socio-economic ripple effect. Existing systems require a large-capacity battery to drive signal processing, wireless transmission part, and an operating system in the process. However, due to the limitation of the battery capacity, it causes a spatio-temporal limitation on the use of the device. This limitation can act as a cause for the disconnection of data required for the user's health care monitoring, so it is one of the major obstacles of the health care device. In this study, we report the concept of a standalone healthcare monitoring module, which is based on both triboelectric effects and electromagnetic effects, by converting biomechanical energy into suitable electric energy. The proposed system can be operated independently without an external power source. In particular, the wireless foot pressure measurement monitoring system, which is rationally designed triboelectric sensor (TES), can recognize the user’s walking habits through foot pressure measurement. By applying the triboelectric effects to the contact-separation behavior that occurs during walking, an effective foot pressure sensor was made, the performance of the sensor was verified through an electrical output signal according to the pressure, and its dynamic behavior is measured through a signal processing circuit using a capacitor. In addition, the biomechanical energy dissipated during walking is harvested as electrical energy by using the electromagnetic induction effect to be used as a power source for wireless transmission and signal processing. Therefore, the proposed system has a great potential to reduce the inconvenience of charging caused by limited battery capacity and to overcome the problem of data disconnection.

Patient Anxiety and Communication Experience in the Emergency Department: A Mobile, Web-Based, Mixed-Methods Study on Patient Isolation During the COVID-19 Pandemic

Kim Sumin,Chang Hansol,Kim Taerim,Cha Won Chul 대한의학회 2023 Journal of Korean medical science Vol.38 No.39

Background: Anxiety and communication difficulties in the emergency department (ED) may increase for various reasons, including isolation due to coronavirus disease 2019 (COVID-19). However, little research on anxiety and communication in EDs exists. This study explored the isolation-related anxiety and communication experiences of ED patients during the COVID-19 pandemic. Methods: A prospective mixed-methods study was conducted from May to August 2021 at the Samsung Medical Center ED, Seoul. There were two patient groups: isolation and control. Patients measured their anxiety using the State-Trait Anxiety Inventory (STAI X1) at two time points, and we surveyed patients at two time points about factors contributing to their anxiety and communication experiences. These were measured through a mobile web-based survey. Researchers interviewed patients after their discharge. Results: ED patients were not anxious regardless of isolation, and there was no statistical significance between each group at the two time points. STAI X1 was 48.4 (standard deviation [SD], 8.0) and 47.3 (SD, 10.9) for early follow-up and 46.3 (SD, 13.0) and 46.2 (SD, 13.6) for late follow-up for the isolation and control groups, respectively. The clinical process was the greatest factor contributing to anxiety as opposed to the physical environment or communication. Communication was satisfactory in 71.4% of the isolation group and 66.7% of the control group. The most important aspects of communication were information about the clinical process and patient status. Conclusion: ED patients were not anxious and were generally satisfied with medical providers’ communication regardless of their isolation status. However, patients need clinical process information for anxiety reduction and better communication.

Silica aerogels are intensively investigated since the past decade for a diverse range of application due to their high surface area, low density, open pore structure and excellent insulation properties. Silica aerogels with high thermal insulation performance mixed with acrylic pressure sensitive adhesives(PSA) applied between the window layers can reduce the coefficient of overall heat transmission of the window. A mixture of the adhesives and silica aerogels attached film can reduce thermal conductivity. Thermal conductivity was measured by a TCi thermal conductivity analyzer.
