Suicide is a behavior that is intended to cause death by itself and requires medical treatment, resulting in suicidal attempt or completion. Suicide causes loss of life, damages the body, costs a lot of medical expenses, and causes families to fall into sorrow and suffering therefore this suicide is a huge loss to family and society. There have been attempts to reduce and prevent suicide by understanding the mechanism of suicide. The mechanism of suicide can be thought of as psychological mechanism and biological mechanism. In the past, if we considered the psychological and biological mechanisms separately, the development of neuroscience now connects and integrates these two. Psychological factors affect biological factors and biological temperaments also affect perception or thinking about the situation and increase psychological vulnerability. Distant factors in suicidal behavior-such as childhood adversity and family and genetic predisposition-increase the lifetime risk of suicide. They alter the response to stress and other processes through changes in gene expression and regulation of emotional and behavioral characteristics. Distant factors affect the biological system and consequently changes in these systems can increase the risk of suicide. In other words, the distal factor does not directly induce suicidal behavior but rather acts indirectly through developmental or mediating factors. These mediating factors are impulsive aggressive and anxious trait, and chronic use of substances. The mechanism of this disorder is the abnormality of the serotonin system and the abnormality of the lipid level. Proximal factors are associated with the onset of suicide events and include changes in the major neurotransmitter systems, inflammatory changes, and dysfunction of glial cells in the brain. A series of studies, including a variety of research methods and postmortem and in-vivo imaging studies, show the impairment of the serotonergic neurotransmitter system and hypothalamic-pituitary-adrenal axis stress response system for suicidal behavior. These disorders lead to suicidal behavior due to difficulty in cognitive control of mood, pessimism, reactive aggression, abnormality in problem solving abilities, excessive response to negative social signals, severe emotional distress, and cognitive dysregulation of suicidal ideation.

본 논문은 교통 감시를 수행하는 고정 카메라에서, 움직이는 물체들의 궤적을 사용자가 입력한 사용자 지정 경로를 바탕으로 그 정상/비정상성을 판별하는 방법을 제안한다. 제안된 방법은 입력된 경로 정보를 미리 정해진 규칙에 따라 각각의 이동 물체에 대한 비정상성(abnormality)을 계산하고 이를 임계값(Threshold)과 비교하여 비정상 행위를 판별해낸다. 사용자의 경로 정보 입력 기능을 이용하기 때문에 기존의 방법들에서 사용한, 계산량과 시간 소모가 크며 학습 데이터에 의해 그 성능이 크게 영향을 받는 정상 행위 (normal behavior) 모델링 단계를 배제하여 보다 빠르고 정확한 판별 결과를 제공한다. 뿐만 아니라 단순히 지정된 규칙만을 이용하지 않고 주어진 환경에 따라 규칙을 변형 적용하여 보다 강인한 판별 결과를 제공한다. 실험 결과는 본 논문에서 제안한 방법이 각종 교통 상황에서 발생하는 불법 및 비정상 교통 행위를 강인하게 판별해 냄을 보여준다.

Surveillance systems play a pivotal role in ensuring the safety and security of various environments, including public spaces, critical infrastructure, and private properties. However, detecting abnormal human behavior in lowlight conditions is a critical yet challenging task due to the inherent limitations of visual data acquisition in such scenarios. This paper introduces a spatiotemporal framework designed to address the unique challenges posed by low-light environments, enhancing the accuracy and efficiency of human abnormality detection in surveillance camera systems. We proposed the pre-processing using lightweight exposure correction, patched frames pose estimation, and optical flow to extract the human behavior flow through t-seconds of frames. After that, we train the estimated-action-flow into autoencoder for abnormal behavior classification to get normal loss as metrics decision for normal/abnormal behavior.

A 4-year-old Thoroughbred mare was brought to the Korea Racing Authority Equine Hospital with heightened sensitivity to touch of the hindquarter, reluctance to step forward, frequent urination even during training, clitoral winking, tail swinging, tail lifting, and training difficulties due to being in constant heat. The trainer claimed that she was in heat and exhibited reduced performance. Physical and lameness examinations revealed no abnormality. Rectal palpation and transrectal ultrasonography revealed normal reproductive organs and estrus. As she exhibited typical estrous behavior without any other physical conditions, the mare was considered to express undesirable estrous behavior. An intrauterine glass ball was inserted into the mare on ovulation day. However, the estrous behaviors were reduced unsatisfactorily. Additionally, 1 mL of peanut oil was administered on the 10th day after the intrauterine device insertion. The mare returned to training and expressed no undesirable estrous behavior over 30 days after the peanut oil treatment. However, further follow-ups were not conduct as the mare was retired to a farm after a limb injury occurred during training. This is the first report of undesirable estrous behavior in a Thoroughbred mare under the rules of racing in Korea. It is recommended that equine clinicians in Korea consider peanut oil as a therapeutic agent to control mares' estrous behavior-related problems.

Hepatic encephalophthy was diagnosed with serum chemistry, abdominal radiography and ultrasonography in a 2.6kg, 4 year-old maltese dog showing signs of hypersalivation, involutary spasm of facial muscles, ataxia, behavior abnormalities like dullness, sleep disorder, restlessness. In serum chemistry, the level of alanine transferase and aspartate trasferase was mildly elevated, ammonia was severely increased. On abdominal radio-graphs, the size of liver was mildly decreased. In ultrasonographic examination, diffuse lesion with hyperechoic change and decreased vasculature were seen in the hepatic region. But vascular abnormalities of liver were not observed. Drug and dietary therapy were undertaken and severities of clinical sign were alleviated.

Intercostal abdominal hernia in the 11th intercostal space was identified in a leopard cat. Although mild leukopenia was found in laboratory examinations, no remarkable abnormality was revealed in medical imaging. To investigate abdominal organs, diagnostic laparoscopy was performed after hernia repair. In laparoscopic view, closure of the herniation site and a lesion with whitish discoloration in the liver (left medial lobe) were observed. Subsequently, laparoscopic liver biopsy was performed against the affected hepatic tissue. Histologically, the sample was diagnosed as mild hepatic lipidosis. Laparoscopy is considered useful for abdominal visceral examination and liver biopsy in a leopard cat patient.

인간은 여러 가지의 관점에서 정의될 수 있다. 첫째는 생물학적인 측면이며, 두 번째는 심리적인 측면이며, 세 번째는 사회적인 측면이다. 생물학적인 측면과 심리적인 측면은 인간내적(intrapersonal)인 면을 다루고, 사회적인 측면은 대인관계(interpersonal)적인 면을 다루고 있다. 인간의 행동이나 정신병리에 대하여는 그 동안 수많은 이론과 가설들이 있어왔으나 몸(body)과 마음(mind), 인간내적인 면과 대인관계적인 면을 동시에 통괄적으로 설명하는 이론은 없다고 할 것이다. 이에 저자는 신체와 정신에 동시에 적용이 가능한 용어들인 '힘(power)과 통제(control) 그리고 생존(survival)'의 개념으로 이 네 가지 측면을 모두 통괄하는 방법을 강구하고자 한다. 즉 힘에는 신체적인 힘, 정신적인 힘, 내적인 힘, 외적인 힘의 네 종류가 있다. 통제에도 역시 신체적인 통제, 정신적인 통제, 내적인 통제, 외적인 통제의 네 종류의 통제가 존재한다. 내적이란 자신에게로 향하는 과정을 의미하며, 외적이란 타인에게로 향하는 과정을 뜻한다. 한 개인에 있어서의 생존과 건강, 인격적 성숙, 성격적인 특성은 이 네 종류의 힘과 네 종류의 통제의 조화와 균형에 의하여 유지될 수 있다. 또한 이에 바탕을 두어 이 네 종류의 힘과 네 종류의 통제의 부조화와 불균형의 특성에 따라서 정상(normality)과 비정상(abnormality)에 대한 새로운 정의를 내리고자 한다.

In this paper we have carried out molecular dynamics simulations (MD) for model systems of liquid n-alkane oligomers ($C_{12}{\sim}C_{80}$) at high temperatures (~2300 K) in a canonical ensemble to calculate viscosity ${\eta}$, self-diffusion constants D, and monomeric friction constant ${\zeta}$. We found that the long chains of these n-alkanes at high temperatures show an abnormality in density and in monomeric friction constant. The behavior of both activation energies, $E_{\eta}$ and $E_D$, and the mass and temperature dependence of ${\eta}$, D, and ${\zeta}$ are discussed.

Functional urinary incontinence, the absence of any neurologic or structural abnormality as a cause of urinary incontinence in children, is one of the most common clinical problems encountered in pediatric and urologic departments, and it can be socially and emotionally distressing for the affected children. The prevalence rates of functional urinary incontinence in school-aged children are not very high and differ between boys and girls. The underlying mechanisms of functional urinary incontinence are heterogenous and can be associated with the following dysfunctions of both the storage and voiding patterns of the bladder: overactive bladder, dysfunctional voiding, lazy bladder syndrome, HinmanAllen syndrome, giggle incontinence, and vaginal voiding. Treatment methods for urinary incontinence in children should be chosen according to these clinical conditions. Treatment modalities generally consist of the treatment of comorbid conditions such as urinary infection and constipation, behavior therapy to modify learned voiding patterns, and pharmacotherapy primarily with anticholinergics and ${\alpha}$-adrenergic blockers. This review discusses the optimal treatment modalities, including treatment of the underlying voiding disorders, and diagnostic approaches related to functional urinary incontinence in children.
