Lewy body dementia (LBD) is the second most common neurodegenerative dementia after Alzheimer’s disease (AD) [1]. LBD includes dementia with Lewy bodies (DLB) and Parkinson’s disease (PD) with dementia (PDD), which share clinical features. DLB and PDD are classified according to the timing of the onset of dementia in relation to that of motor symptoms. PDD and DLB show similar neuropathological changes, such as cortical and brainstem Lewy bodies accompanied by varying degrees of AD pathology.

Superficial siderosis results from the deposition of hemosiderin in subpial layers of the central nervous system following hemorrhage in subarachnoid spaces. Infratentorial superficial siderosis (ISS) presents with unique clinical features including progressive hearing loss, ataxia, and myelopathy, and the most common cause of idiopathic ISS is dural abnormality. Here we report a case of idiopathic ISS with radiological findings of spontaneous intracranial hypotension, whose clinical symptoms of ISS including cerebellar dysfunction improved after supine position was maintained for 2 months.

In this article, we review the study trends of three-dimensional (3D) displays that can display stereoscopic images from the perspective of a display device. 3D display technology can be divided into light field, holographic, and volume displays. Light field display is a display that can reproduce the intensity and direction of light or 'ray' in each pixel. It can display stereoscopic images with less information than a holographic display and does not require coherence of the light source. Therefore, it is expected that it will be commercialized before the holographic display. Meanwhile, the holographic display creates a stereoscopic image by completely reproducing the wavefront of an image using diffraction in terms of wave characteristics of light. This technology is considered to be able to obtain the most complete stereoscopic image, and the digital holographic display using a spatial light modulator (SLM) is expected to be the ultimate stereoscopic display. However, the digital holographic display still experiences the problem of a narrow viewing angle due to the finite pixel pitch of the SLM. Therefore, various attempts have been made at solving this problem. Volumetric display is a technology that directly creates a stereoscopic image by forming a spatial pixel, which is known as a volumetric pixel, in a physical space, and has a significant advantage in that it can easily solve the problem of the viewing angle. This technology has already been tested for commercial purposes by several leading companies. In this paper, we will examine recent research trends regarding these 3D displays and near-eye display that is emerging as a significant application field of these technologies.

UAM (Urban Air Mobility) is a new safe, secure, and more sustainable air transportation system for passengers and cargo in urban environments. Commercial operations of UAM are expected to start in 2025. Since production rates of UAM are expected to be closer to cars than conventional aircraft, the airworthiness methodology for UAM must be prepared for mass production. Composite materials are expected to be mainly used for UAM structures to reduce weight. In this paper, the composite material qualification method was derived and the materials were applied for small aircraft application. It is expected to reduce the airworthiness certification time by applying composite material qualification system and its database.

Unilobular atrophy or hypoplasia involving the hepatic lobes is not uncommon on the left side. It is distinctly uncommon on the right, where it probably represents an developmental anomaly if no other etiological factor is demonstrable. So we report a case of hypoplasia of right hepatic lobe.

A micromachined sensor part for an infrared focal plane array has been designed and fabricated. Amorphous silicon was adapted as a sensing material, and silicon nitride was used as a membrane material. To get a good efficiency of infrared absorption, the sensor was made as a λ/4 cavity structure. All the processes were done in 0.5 ㎛ iMEMS fab. in the Electronics and Telecommunication Research Institute (ETRI). The processed MEMS sensor structure had a small membrane deflection less than 0.3 ㎛. This excellent deflection property can be attributed to the rigorous balancing of the stresses of individual layers. The efficiency of infrared absorption was more than 75% in the wavelength range 8 - 14 ㎛.

우리나라는 기존의 모방형 혁신체제에서 창조형 혁신체제로의 전환을 통하여 과학기술적 지식의 효율적 창출ㆍ확산ㆍ활용이 필요하다. 이를 위해서는 과학기술혁신의 주체인연구인력의 육성이 핵심적인 필수조건으로 대두되고 있다. 본 논문은 우리나라 국가혁신체제의 핵심 구성요소인 출연연구기관의 창의적 인적자원 양성전략에 관해 논의한다. 본 논문에서는 출연(연)이 과학기술혁신활동을 직접 다루기 때문에 창의적 인적자원의 효율적 관리가 매우 중요성을 강조하고, 이를 위해 ‘전주기적 인적자원관리 모델’을 제시하고 있다. 이 모델은 우수 연구원의 유치, 연구원의 유동성 강화, 우수연구원의 특정자격 부여, 퇴직연구원의 효율적활용의 네 단계로 구성되어 있으며 각 단계별 여러 정책과제를 제시하고 있다. 아울러 본 논문은 본 모델의 각 단계가 서로 선순환 구조를 가져야 할 것을 강조한다. 본 논문에서는 출연(연)은 전주기적 인력관리 모델의 추진을 바탕으로 연구인력을 전공분야의 심층적 지식과 관련 분야의 폭넓은 지식을 가지는 ‘역T자형 인력’으로 육성하여야 함을 강조하고 있다. Korea needs to create, diffuse, and exploit scientific and technological knowledge effectively through transforming its national innovation system from imitative system to creative one. For this purpose, it is necessary for Korea to nurture creative human capital (CHC), which are the main actor of generating S&T and innovation. This paper aims at discussing the strategies of nurturing creative human capital of government-sponsored research institutes (GRIs). In this paper, we argue that the management of creative human capital is particularly important for Korean GRIs because they deals directly with scientific and technological activities. For effective management of GRIs` creative human capital, we suggest a Model for Life Cycle Management of Creative Human Capital. This model is composed of four stages: inviting well-qualified researchers, strengthening mobility of researchers, providing special certificates to excellent researchers, and effectively exploiting retired researchers. We emphasize that each stage should form and reinforce a virtuous cycle. This paper argues that GRIs` creative human capital should be nurtured as `Inverse T-Type Manpower`, who have not only deep knowledge on their own special S&T areas but also broad knowledge on related areas, based on this Life Cycle Management Model.

중등학교 가창 교육의 실태 분석

양인준,조성기 한국음악교육공학회 2022 음악교육공학 Vol.- No.50

The purpose of this research is to understand the contents and actual conditions of how singing education is being conducted in the secondary school field. To this end, various literature on the contents and methods of singing education was reviewed, and based on this, a survey tool was developed for the actual situation and needs of singing education, and statistics on 105 respondents were analyzed. As a result of the analysis, it was found that secondary school music teachers still recognized the necessity of singing education as important. However, there is a big change in actual music classes, and it can be confirmed that the time devoted to singing education is decreasing as singing classes are being conducted less than listening or instrumental classes. In the content of singing education, popular songs and popular music are highly preferred as songs for singing classes, and learning about breathing, vocalization, and musical elements is relatively well done, but education for sight-singing and creative expression is somewhat insufficient. In the method of singing and singing education, it was found that education through the teacher's demonstration window and listening and singing was centered, and education by solmization was not well conducted. 본 연구는 중등학교 현장에서 가창 교육이 어떻게 이루어지고 있는지 그 내용과 실태를 파악하는 데에 목적을 두었다. 이를 위해 가창 교육의 내용과 방법에 대한 다양한 문헌을 고찰하였고, 이를 토대로 가창 교육의 실태와 요구를 위한 조사 도구를 개발하여 전국의 중․고등학교 음악 교사를 대상으로 조사를 시행하였고 응답자 105명의 응답 내용에 대한 통계를 분석하였다. 분석 결과, 중등학교 음악 교사들은 여전히 가창 교육의 필요성에 대해 중요하게 인식하고 있는 것으로 나타났다. 그러나 실제 음악 수업에서는 큰 변화가 나타나고 있는데, 가창 수업이 감상이나 기악 수업에 비해 적게 이루어지고 있음으로써 가창 교육에 할애하는 시간이 줄고 있음을 확인할 수 있었다. 가창 교육의 내용에서는 대중가요나 대중음악이 가창 제재곡으로서 그 비중이 높게 선호되고 있는 것으로 나타나고 있으며, 호흡법이나 발성법, 그리고 음악 요소에 대한 학습은 비교적 잘 이루어지고 있으나 시창 교육이나 창의적인 표현을 위한 교육은 다소 미흡한 것으로 나타났다. 가창 교육의 방법에서는 교사의 시범창과 듣고 따라부르기를 통한 교육이 중심을 이루고 있는 것으로 나타났고, 계명창에 의한 교육은 잘 이루어지지 않는 것으로 나타났다.
