Capturing Korea’s Social Issues using KR-Word Bank Algorithm
Jiyoon Shin(신지윤),Jungwoo Lee(이정우) 한국통신학회 2021 한국통신학회 학술대회논문집 Vol.2021 No.2
In this paper, we apply the Cheongwadae National Petition data to the KR-WordBank to extract keywords for social issues by category and era. The Cheong-WaDae National petition site allows anyone of all ages to register petitions, and it is safe to assume that it expresses people’s social interests and issues because mischief petitions are filtered through a series of processes. As the importance of NLP in deep learning emerged, WordBank, which can extract keywords after excluding unnecessary words from the text dataset, and KR-WordBank, which can be applied to Korean, were released. We used the KR-WordBank to propose our method.
3D MRI Imputation Using Learned Registration Fields
Jiyoon Shin(신지윤),Jungwoo Lee(이정우) 한국통신학회 2022 한국통신학회 학술대회논문집 Vol.2022 No.2
An MRI 3D volume is represented by a number of imaging sequences such as T1-weighted, T2-weighted, and Flair; each sequence volume is visualized by a group of two-dimensional scans in a particular plane. In practical MRI, some scans are often missing while many medical applications require a full set of scans. An MRI imputation method is presented, which synthesizes such missing scans. Key components in this method are the index registration field $\Phi$ and the intensity registration field $\Psi$. The $\Phi$ models anatomical differences between two scans of different index in the same imaging sequence, and $\Psi$ reflects the image contrast difference between two scans of same index but in different imaging sequence. The two registration fields allow two estimates of a missing scan, one within corresponding imaging sequence and another along scan index; the two estimates are combined to yield the final synthesized scan. In experiments, the proposed imputation method is compared to VoxelMorph, pGAN-cGAN, and CollaGAN. It takes both anatomical- and contrast-changes into account through two registration fields, while other methods fail to reflect both. This is clear in visual comparison of synthesized images; the proposed method yields images with higher visual quality and richer details, especially in subtle parts located in the center of scan. Quantitative comparison through measures such as SSIM, NSME, and PSNR also demonstrate the superiority of the proposed imputation.

It is necessary to find ways to improve North Koreas power infrastructure in response to climate change. North Korea should adopt a power supply system consistent with sustainable development that can curb carbon emissions and ensure economic growth. South Korea needs a practical cooperation plan that can be positive to each other by utilizing North Korea while simultaneously promoting inter-Korean economic cooperation and its energy transition. Meanwhile, amid rising vulnerabilities to climate change in North Korea, calls for a global joint response to climate change are growing. North Koreas plan to improve its power infrastructure is thus asking what kind of power supply system and what kind of implementation system will be best from the perspective of climate change response. As a research method, a comparative analysis was used to see if the proposed power supply plan to North Korea from the perspective of South Korea corresponds to the priority of power-related policies shown in North Koreas Conditional NDC. In order to derive proposals from South Korea, (1) objectified North Koreas electricity and climate crisis situation based on North Koreas VNR, (2) reinterpreted existing studies on North Koreas electricity supply by energy source by reflecting recent economic analysis and climate finance conditions, and (3) went through a process of exploring improvements related to the implementation system focusing on case analysis. As a result of the study, it is desirable to divide the power supply system to North Korea into three. First, it is a small-scale renewable energy supply for home that would be possible in the short term due to the nature of humanitarian aid. Second, it is support for the maintenance and repair of the power system corresponding to the reduction of the loss rate of transmission and distribution, which North Korea has placed at the top of its policy preference. Third, it is a utility scale renewable energy supply corresponding to the long-term renewable energy growth strategy of North Korea. This can be a necessary power supply for the economic cooperation zone, and it is desirable to secure the profitability of the project through emission reduction scheme. In the long run, it will be possible to seek connection with North Korea to overcome the network stability problem in the process of expanding renewable energy in South Korea.

Objectives: This study was conducted to investigate the reliability and validity of the Korean version of the DSM-5 Level 2 Cross-Cutting Symptom Measure–inattention [Swanson, Nolan and Pelham, version IV (SNAP-IV)] and anger [Patient-Reported Outcome Measurement Information System (PROMIS) Anger] for parents and guardians of children aged 6–17 years. Methods: We included 104 children and adolescents diagnosed with attention-deficit/hyperactivity disorder (ADHD), ADHD with anxiety and depression, depressive disorder, anxiety disorder, and tic disorder with somatic symptoms (ADHD=41, depression=9, anxiety=14, ADHD+anxious depression=11, tic+somatic symptoms=29). Their ages ranged from 8 years to 15 years. The participants’ mothers completed the SNAP-IV, PROMIS Anger scale, Korean version of the IOWA Conners Rating Scale (K-IOWA), and Korean ADHD Rating Scale (K-ARS) so that the reliability and validity of the SNAP-IV and PROMIS Anger scales, which are DSM-5 scales for assessing inattention and anger of children and adolescents, could be examined. Results: The reliability coefficient of SNAP-IV (Cronbach’s α) was 0.94. The correlation coefficients between SNAP-IV, K-IOWA inattention, and K-ARS inattention scores ranged from 0.73 to 0.86. The mean SNAP-IV scores of the ADHD and the ADHD+anxious depression groups were significantly higher than those of the anxiety and the tic+somatic symptoms groups. The reliability coefficient of the PROMIS Anger was 0.91. The correlation coefficient between PROMIS Anger and K-IOWA oppositional/defiant scores was 0.75. The PROMIS Anger mean score of the ADHD+anxious depression group tended to be higher than that of the other groups. Conclusion: These results suggest that the Korean version of the DSM-5 Level 2 Cross-Cutting Symptom Measure–inattention and anger for parent and guardian of child age 6–17 might be a reliable and valid test and may be useful for screening children and adolescents with ADHD.

최근 스마트기기가 발전함에 따라 종이책이 아닌 다양한 전자책뷰어가 등장하고 있다. 애플의 아이패드(iPad), 아마존의 킨들(kindle)과 같은 태블릿, 전자책 또는 스마트폰이 대표적인 예이며 스마트기기의 사용자 증가로 전용 단말기가 아닌 스마트폰 중심의 전자책 시장도 크게 성장하고 있다. 하지만 시니어 또는 스마트기기 사용을 어려워하는 사용자들이 전자책을 사용하는데 어려움을 느끼기 때문에, 전자책은 종이책에 비해 여전히 낮은 이용률을 나타내고 있다. 본 논문에서는 얼굴 표정에 따라서 전자책 설정을 자동으로 변경해 주는 방법을 제안한다. 제안한 방법은 표정감지를 위하여 OpenCV 라이브러리를 이용하여 얼굴을 검출하고, Haar-Like 피처 기법으로 사용자의 눈 모양을 검출한다. 눈이 감겨있는 경우와 찌푸린 경우를 감지하여 이에 맞게 글자크기와 화면을 자동으로 설정해 준다.
