In recent years, large-scale events and festivals face the potential for critical incidents. To prevent these incidents, CNN-based crowd-counting systems with high accuracy, such as CSRNet, are proposed. However, their extensive parameter size limits its application on mobile and edge devices. To solve this problem, RTL-based AI accelerators, which design processing engines optimized for AI models, are attracting a attention as an alternative platform to GPU due to their advantages of low power and lost cost. This paper proposes a CNN-based crowd counting system by designing CSRNet on the FPGA platform. In terms of algorithm optimization, we applied pruning and quantization to CSRNet to reduce the parameter size, and in terms of hardware design, we applied loop unrolling and dataflow optimization to parallelize operations and conducted a design based on data reuse patterns. As a result of Xilinx Ultrascale+ MPSoC ZCU102 implementation, the proposed IP uses only 24.92% of LUTs, 2.88% of FFs, and 3.17% of DSPs while offering advantages in terms of low power consumption and cost-effectiveness compared to GPUs.

최근 자폐 스펙트럼 장애(ASD)가 보이는 사회적 상호작용의 어려움을 얼굴 지각과 눈맞춤 측면에서 설명하는 이론이 발표됨에 따라 이에 근거한 사회성 증진 훈련 프로그램이 개발되어 효과성이 검증되기 시작하였다. 주로 전자기기를 사용하는 이 새로운 형태의 사회성 증진 훈련 프로그램은 비록 그 수는 매우 제한되지만, 비용 효율적이고 접근성이 높다는 장점이 있다. 본 연구에서는 얼굴인식 및 사회성 향상을 중점으로 하는 앱 반 훈련 프로그램(Look At Me)을 개발하고, ASD 아동 및 청소년을 대상으로 예비 연구를 실시함으로써 실제 훈련 프로그램으로서의 적용 가능성을 확인하고자 하였다. 연구 참가자는 ASD 진단 기준을 충족한 28명의 참가자였다. 모든 참가자들은 8주(56일) 동안 훈련을 실시하였으며, 훈련의 효과성을 측정하기 위해 보호자를 대상으로 훈련 전, 후로 설문을 실시하였다. 분석 결과, 자폐 성향 설문지 상에서는 차이가 없었으나, 사회적 반응성 설문지 및 반구조화 설문 중 눈맞춤, 정서이해 및 표현 등 하위 영역에서 유의한 향상을 보인 것으로 나타났다. 본 연구 결과를 바탕으로 훈련 프로그램의 효과성을 논의하고, 추후 지각 수준의 사회성 훈련 패러다임의 근거 기반 치료와 및 향후 얼굴 지각 훈련 프로그램 제작 방향을 제시하였다. Recently, the difficulty in social interaction in those with autism spectrum disorder (ASD) has been explained in terms of face perception and eye contact. Appropriately, based on this theory, the effectiveness of social enhancement training programs is now being researched. This new form of social enhancement training program which primarily uses electronic devices, is limited in number but has the advantage of being cost-effective and highly accessible. In this study, we developed an application-based training program(Look At Me) focusing on face perception and social enhancement, and conducted a preliminary study on children and adolescents with ASD to explore the actual applicability of the training program. Participants of the study were 28 study participants who met the ASD diagnostic criteria. Participants were trained through the application-based program for 8 weeks(56 days) and parents completed questionnaires before and after the training to measure the effectiveness of the program. The results in terms of the questionnaires showed no significant difference in autistic symptoms, but there was significant improvement in sub-domains such as the social reaction questionnaire and semi-structured questionnaire, eye-contact, and emotional understanding, expression and etc. Taking these results into consideration, the effectiveness of the training program is discussed, and evidence-based social training for social improvement and direction of future face perception training programs are suggested.

수면과 분노

Anger is a multi-dimensional concept ranging from feeling irritable to violent aggression. A growing body of literature suggests the relevance of sleep in regard to anger. The current study aims to review previous studies on the association between anger and diverse aspects of sleep including sleep disruption, chronotype, sleep disorders and sleep deprivation. An association between sleep and anger has been observed starting in the early stage of life, with sleep of infants or toddlers affecting emotional and behavioral aspects of anger. However, the association between anger and sleep is not clear in adolescents and might be due to the effects of psychosocial factors on both sleep and anger during adolescence. Subjective but not objective sleep disturbances of adults have been also associated with anger. Evening types showed more anger, which might be mediated by psychological characteristics or social jet lag of evening people. Increased anger has also been found in those with insomnia, sleep apnea, or experimental sleep-deprivation. Previous studies have reported that diverse sleep disturbances are related to anger. Future study assessing the various sleep or circadian indices and considering the multidimensional aspects of anger are needed.

With an incidence of 1 per 2,500-3,000 individuals, neurofibromatosis type 1 (NF1) is the most common autosomal dominant disorder in humans. NF1 is caused by germline mutations of the NF1 gene, but to date genotype-phenotype analyses have indicated no clear relationship between specific gene mutations and the clinical features of this disease, even among family members with the same mutation. The present study describes a case of two siblings with NF1 with the same genetic mutation but different clinical manifestations. The first patient was a female with iris Lisch nodules, an adrenal incidentaloma, Graves’ disease, and skin manifestations, while the second patient, the first patient’s younger brother, exhibited only skin neurofibromas and freckling. Further study is needed to reveal the molecular processes underlying gene expression and phenotypes. A better understanding of the genetics associated with NF1 will allow clinicians to detect complications earlier and provide better genetic counseling to NF1 families. (Korean J Med 2016;90:455-459)

Objectives : The purpose of this study is to investigate on the application of the yttrium aluminum garnet (YAG) lasers for acupoints irradiation. Methods : We conducted a systematic search for peer-reviewed studies published from inception to November 2023, in the following electronic databases: PubMed, Scopus, and Web of Science in English, Science ON, Oriental Medicine Advanced Searching Integrated System (OASIS) and Research Information Sharing Service (RISS) in Korean, and China National Knowledge Infrastructure (CNKI) and Wanfang in Chinese, and Japan Science Technology Information Aggregator, Electronic (J-STAGE) and Citation Information by NII (CiNii) in Japanese. Inclusion criteria were original articles including clinical and experimental studies related with YAG lasers for acupoints including Ashi or meridian sinews. Results : Among the 8 selected studies, there were 7 studies on human subjects and 1 study on animals, 7 studies on Nd:YAG (1,064 nm) laser, and 1 study on Er:YAG (2,940 nm) laser. A total of 16 acupoints were used, 15 of which were in the face and 1 of which was located in the foot. In addition, there were two studies using Ashi. 4 studies looked at the effect of pain relief, 2 studies looked at safety, 1 study looked at changes in blood flow, and 1 study looked at the effect of skin care. There were no reported adverse events, and the YAG laser was confirmed to be safe and effective in pain relief, beautifying the skin, and increasing blood flow. Conclusions : We suggest that high intensity YAG lasers can be applied to laser acupuncture or laser moxibustion. YAG lasers are considered to be worth using for various clinical indications of Korean medicine because of photobiomodulation effects, analgesic action, and deep penetration depth. Further scientific research and clinical evidences should be warranted.
