  • Skin lesions are common diseases that range from skin rashes to skin cancer, which can lead to death. Note that early diagnosis of skin diseases can be important because early diagnosis of skin diseases considerably can reduce the course of treatment and the harmful effect of the disease. Recently, the development of computer-aided diagnosis (CAD) systems based on artificial intelligence has been actively made for the early diagnosis of skin diseases. In a typical CAD system, the accurate classification of skin lesion types is of great importance for improving the diagnosis performance. Motivated by this, we propose a novel deep ensemble classification with multi-scale attention networks. The proposed deep ensemble networks are jointly trained using a single loss function in an end-to-end manner. In addition, the proposed deep ensemble network is equipped with a multi-scale attention mechanism and segmentation information of the original skin input image, which improves the classification performance. To demonstrate our method, the publicly available human skin disease dataset (HAM 10000) and the private animal skin lesion dataset were used for the evaluation. Experiment results showed that the proposed methods can achieve 97.8% and 81% accuracy on each HAM10000 and animal skin lesion dataset. This research work would be useful for developing a more reliable CAD system which helps doctors early diagnose skin diseases.

  • Recently, as elderly people suffering from chronic diseases have increased and disasters such as traffic accidents have increased, urgent rescue workers and doctors need to respond effectively to such emergencies. For elderly people, the difficulty in communicating their condition especially the health condition during disaster is one of the problems in which delay on immediate handling by rescue team can cause death. Providing a solution for this problem is one of the main issues in our research. In this paper, we use the QR code to communicate the minimum personal information and medical history needed for emergency medical treatment to emergency medical personnel, and to transmit the medical history and treatment data to the doctors of the hospital through QR code and fingerprint recognition, respectively. Especially, by using both QR code of smart phone and fingerprint of individual, we can protects personal information and strengthens privacy and security of medical information by allowing only authorized physicians to check medical records of the old patient.

  • Seizures are the most common clinical symptom of a neurologic insult and have long been recognized as an obvious marker of brain dysfunction in newborns. Presence of seizures in newborn infants may signify substantial risk for subsequent neurodevelopmental impairment including postneonatal epilepsy and death. The outcomes of seizures in neonates are determined mainly by the etiology of the seizures. Despite the decreasing trend of mortality of neonatal seizures, the prevalence of long-term neurodevelopmental sequelae in survivors has remained unchanged over time. Clinical studies have contributed to identifying significant prognostic factors for neurodevelopmental outcome. The underlying etiology of the seizures and electroencepaphalography background pattern are considered as most reliable early predictors of later neurologic sequelae. However, clinicians managing neonatal seizures are still challenged by difficult therapeutic and prognostic questions because of many unresolved issues in seizure recognition, terminology, relationships to the underlying brain lesion, effect of current management, particularly antiepileptic drugs on long-term outcomes. This review presents the prognosis of neonatal seizures, especially about mortality and neurodevelopmental deficit, and predictors of outcomes.

  • Abusive head trauma (AHT) is the most common and serious form of child abuse and a leading cause of traumatic death in infants and young children. The biomechanics of head injuries include violent shaking, blunt impact, or a combination of both. Neuroimaging plays an important role in recognizing and distinguishing abusive injuries from lesions from accidental trauma or other causes, because clinical presentation and medical history are often nonspecific and ambiguous in this age group. Understanding common imaging features of AHT can increase recognition with high specificity for AHT. In this review, we discuss the biomechanics of AHT, imaging features of AHT, and other conditions that mimic AHT.

  • When plants are infected by plant pathogens, rapid cell responses are initiated for further inhibition from fast invasion of pathogens. Hypersensitive response (HR) of plant is well known defense response stopping pathogenesis process through rapid cell death. However, informations on the signaling pathway from reception of pathogen by host plants to appropriate resistant responses are very limited to date. Efficient perception of infection by pathogens and well-programmed signalling mechanism for appropriate responses are important for survival of plants. Plant have developed a sophisticated network(s) of defense/stress responses, among which one of the earliest signalling pathways after perception (of stimuli) is the evolutionary conserved Rop GTPase and mitogen-activated protein kinase (MAPK) cascade.(중략)

  • Acute respiratory failure has become an increasingly frequent cause of death following shock or trauma. Interstitial or diffuse alveolar edema, as chief pathophysiologic change of acute respiratory insufficiency, can be the result of sepsis, fat embolism, cardiac failure, lung congestion, and oxygen toxicity. These pulmonary problems are extremely difficult to treat without early recognition of their development and aggressive management. If the treatment is delayed, the progressive respiratory failure is almost uniformly fatal. Authors have experienced two cases of acute respiratory insufficiency following the blunt chest trauma, which were healed uneventfully. Literatures were briefly reviewed.

  • Caspase 3, a member of cysteine protease family, is well known as a major apoptosis effector and is involved in cell death as a result of ischemic diseases such as stroke and myocardial infarction, therefore the inhibition of caspase 3 may protect those apoptotic cell damages. During the high-throughput screening of the compounds from the Korea Chemical Bank, berberine derivatives (A and B), an isoquinoline alkaloid, have been identified as potential inhibitors for caspase 3. Based on this finding we carried out molecular modeling study to identify the pharmacophoric elements of berberine structure which interact with a substrate-recognition binding site of caspase 3 and came up with several novel scaffolds. In this report, we will discuss the molecular modeling, syntheses and the enzyme inhibitory activities of these novel compounds.

  • Injury is a serious problem that not only causes death but also significantly degrades the quality of life of the people and causes loss of socioeconomic opportunities and costs. Damage occurs as a result of an accident. Among them, natural disasters and artificial disasters take lives of many people in a short time and threaten their physical and mental health. The United States has responded to the disaster by establishing relevant laws and regulations and a response system with the recognition that health is recognised soon to be as national security in the wake of the 9/11 terrorist attacks and the Katrina disaster. It is necessary to build a knowledge infrastructure to train disaster response experts in public health area and to have health competence to cope with disasters.

  • Background: Although working hours have decreased in Korea, they are still high compared to that of other countries. In Korea, cardiovascular and cerebrovascular diseases (CCVDs) related to overwork in Korea continually occur, and the social burden from overwork is estimated to be high. This study investigated the amendment of regulations affecting the approval rate of occupational CCVDs. Methods: The change in approval rate of occupational CCVDs and related regulations were investigated using the Act and public notice on the standards for recognition of occupational CCVDs and the yearbooks of the Ministry of Employment and Labor. The CCVD mortality was estimated using data on the number of deaths according to the cause of death, the number of employed people, and resident registration population aged 15-64 years. The cumulative mortality of CCVDs was estimated using the Kaplan-Meier method. Results: Since the establishment of the standards for recognition in Korea in 1982, the scope of occupational diseases has been expanded to include intracerebral hemorrhage, subarachnoid hemorrhage, cerebral infarction, myocardial infarction, and aortic dissection. In 2013, the concept of working hours was introduced in chronic overwork. The approval rate of occupational CCVDs was 44.7% in 2006, which decreased to 12.9% in 2011. After the improvement of related regulations, the approval rate increased to 41.3% in 2018. From 2000 to 2017, the CCVD mortality of both the unemployed and employed tended to decrease, and their cumulative CCVD mortalities were 549.3 and 319.7 per 100,000 people, respectively. Conclusions: CCVDs are recognized as occupational diseases in Korea. The amendments to the standards for recognition, the introduction of the Occupational Disease Adjudication Committee, the principle of presumption, and the reduction of working hours have changed the approval rate of occupational CCVDs. A strategic approach is needed to further reduce the incidence of CCVDs.

  • This study investigates the funeral rituals practiced by the Joseon Dynasty as recorded about Lee Mun Geon (1494~1567, a.k.a Mukjae), who mourned by the grave of his deceased mother, Ms. Shin (1463~1535), a woman whose family's origin was Goryeon. The study focuse on the rituals performed by Lee after his mother's death, his participation in the funeral, and his mourning specifically as an individual who has lost his parent. Reviewing Lee's mourning life beside the grave, the contents of diary belonging to a nobleman in the middle of Joseon Dynasty were studied aimsing to find out the meaning of rituals, the overall recognition accorded to death, and the filial duties that were carried out by the noblemen of the time. Although noblemen in the middle of Joseon Dynasty ceaselessly attempted to change the observance of funeral rituals through legislation, it was difficult to change the mindset of the people, who fllowed the deep-rooted traditions of long history. It must be acknowledged that the Joseon Dynasty had a different cultural background than that of China. There was a fundamental problem when they tried to adapt The Family Rituals of Zhu Xi, followed by the Chinese, to the Joseon society. Although The Family Rituals of Zhu Xi emphasized ancestral rites focusing on enshrining mortuary tablets and the importance of establishing the family shrine hundred times, noblemen in the mid-Joseon Dynasty period cared for their parents in the grave by mourning for them than by following such practice. The solemn memorial service held in front of the grave, and the annual ritual service on the death anniversary were far more important to the noblemen in the mid-Joseon Dynasty. Amid such contradictions, the noblemen accepted and performed the mourning rituals beside the grave of their parent. Human beings across the ages have always dwelt upon thoughts of the afterlife. Most people believe that they attain a state after the death of their physicalbody. If humans did not have such thoughts, they would not be bothered if death occurs on being hit by a car on the street. Thus, human beings often think of the ritual services related to death, although in different forms. Therefore, mourning by the grave of their parent held great significance among the noblemen of the Joseon Dynasty as a sign of their filial piety.
