  • If the software is developed to analyze the speech disorder, the application of various converged areas will be very high. This paper implements the user-friendly program based on CART(Classification and regression trees) analysis to distinguish between normal and pathological voices utilizing combination of the acoustical and HOS(Higher-order statistics) parameters. It means convergence between medical information and signal processing. Then the acoustical parameters are Jitter(%) and Shimmer(%). The proposed HOS parameters are means and variances of skewness(MOS and VOS) and kurtosis(MOK and VOK). Database consist of 53 normal and 173 pathological voices distributed by Kay Elemetrics. When the acoustical and proposed parameters together are used to generate the decision tree, the average accuracy is 83.11%. Finally, we developed a program with more user-friendly interface and frameworks.

  • Malformations of cortical development are rare congenital anomalies of the cerebral cortex, wherein patients present with intractable epilepsy and various degrees of developmental delay. Cases show a spectrum of anomalous cortical formations with diverse anatomic and morphological abnormalities, a variety of genetic causes, and different clinical presentations. Brain magnetic resonance imaging has been of great help in determining the exact morphologies of cortical malformations. The hypothetical mechanisms of malformation include interruptions during the formation of cerebral cortex in the form of viral infection, genetic causes, and vascular events. Recent remarkable developments in genetic analysis methods have improved our understanding of these pathological mechanisms. The present review will discuss normal cortical development, the current proposed malformation classifications, and the diagnostic approach for malformations of cortical development.

  • Spinal epidural lipomatosis (SEL) is a rare condition of pathological overgrowth of fat tissue in the vertebral canal. SEL leads to back pain, radiculopathy or paraparesis. Glucocorticoids seem to play a major role in the development of SEL. SEL is best diagnosed by magnetic resonance imaging. The treatment of SEL is directed at reducing the body weight and decreasing the excess glucocorticoid. In severe cases, decompressive laminectomy with removal of the excess epidural fat might become necessary to alleviate the neurological symptoms caused by spinal cord compression.

  • Bovine viral leukosis is a viral disease of cattle characterized by the development of tumors in the lymphatic tissue. A female Holstein, 3-year-old, was submitted for diagnosis at the Diagnostic laboratory, Chonbuk National University. Clinical sign of the affected animal showed emaciation, enlargement of superficial lymph node and mild diarrhea. Remarkable lesions were enlargement of many internal lymph nodes. Histopathology revealed excessive neoplastic lymphoid cells characteristic of BVL infection. Subsequently, serums from all cattle were collected and serological examination was done where a 85% seropositive rate was detected using ELISA test. ELISA method showed a comparatively 75% higher detection rate than the agar gel immunodiffusion (AGID) test (85% vs 40%). Serologically positive cattle were variably detected in all ages from under 1 year to over 6 year of age. Hematological examination consistently showed leukocytosis and a differential lymphocytosis of seropositive cattle. Detailed comparative pathological and serological data diagnosed the presence of bovine viral leukosis.

  • Tau proteins, which stabilize the structure and regulate the dynamics of microtubules, also play important roles in axonal transport and signal transduction. Tau proteins are missorted, aggregated, and found as tau inclusions under many pathological conditions associated with neurodegenerative disorders, which are collectively known as tauopathies. In the adult human brain, tau protein can be expressed in six isoforms due to alternative splicing. The aberrant splicing of tau pre-mRNA has been consistently identified in a variety of tauopathies but is not restricted to these types of disorders as it is also present in patients with non-tau proteinopathies and RNAopathies. Tau mis-splicing results in isoform-specific impairments in normal physiological function and enhanced recruitment of excessive tau isoforms into the pathological process. A variety of factors are involved in the complex set of mechanisms underlying tau mis-splicing, but variation in the cis-element, methylation of the MAPT gene, genetic polymorphisms, the quantity and activity of spliceosomal proteins, and the patency of other RNA-binding proteins, are related to aberrant splicing. Currently, there is a lack of appropriate therapeutic strategies aimed at correcting the tau mis-splicing process in patients with neurodegenerative disorders. Thus, a more comprehensive understanding of the relationship between tau mis-splicing and neurodegenerative disorders will aid in the development of efficient therapeutic strategies for patients with a tauopathy or other, related neurodegenerative disorders.

  • Objectives : This study explores perspectives, reasons, functions of dreams in order to develop a treatment model. Methods : We searched CNKI, KISS, NDSL. Papers published since 2002, which are classified in categories. Results : 1. The Recognitions about the dream of Oriental Medicine is based on "Hwangjenaegyeong Eumsabalmong(黃帝內經 淫邪發夢)". 2. By each era, There are a variety of etiological causes, stages. 3. Dreams are generated by the internal stimuli Physiological activities of the Jangbu(臟腑),Deficiencies of yin and yang(陰陽), Pathological changes in the Jangbu(臟腑), Pathology products, external stimuli Yukeum(六淫), Eumsiksang(飮食傷), and unusual feelings. 4. Spirit(神) comes from brain(腦), not heart(心). So what we call brain spirit(腦神) is right. Dreams are the mental activity related to the brain. 5. Dreams are the reflection of the pathological changes of the human body. And it shows the development, changes and prognosis of disease. Dreams sometimes illustrate the incidence of the disease Conclusions : We organized perspectives, Causes and Functions of dreams mentioned in Oriental Medicine Literatures. Health is closely related to the dream. Therefore, we propose that the dream is worth for the diagnosis and treatment in oriental medicine.

  • Tumoral calcinosis is a condition characterized by deposition of calcium salts in the skin and subcutaneous tissue, commonly found around the joints. However, tumoral calcinosis of the auricle is extremely rare. We present the case of a 13-year-old boy with tumoral calcinosis of the helix of the ear auricle. A 13-year-old boy presented with a 10-year history of an enlarging mass on the left auricle. The mass was hard, non-tender, and non-compressible. The patient had no history of trauma. Complete surgical excision and pathological examination of the specimen was performed. The final diagnosis of the excised mass was tumoral calcinosis. After 9 months of follow-up, there were no signs of recurrence of the tumor and the patient was satisfied with the surgical results. Tumoral calcinosis of the auricle is extremely rare and may be misdiagnosed as other tumors. Pathological examination is essential for definitive diagnosis and complete surgical excision should be considered as the treatment of choice.

  • One of the most striking features of modern society in the 21st century, is increased levels of aggression. Aggression refers to aggressive or hostile behavior, and is manifested in suicide or an attack against others. Aggression in modern society is more accidental, reckless, and aimless than before. As more patients visit hospitals due to the serious problem of aggression control, we need to address the nature of this growing aggression. The authors analyzed sources and the nature of aggression, based on the movie 'American Psycho.' The main character of the movie, Patrick, is similar to many people today, with traits such as egotistical thinking, lack of empathy, demand for attention and admiration, and exploited and superficial relationships. Patrick's aggression is in reaction to narcissistic injury. Through this, one can think of pathological narcissism, behind growing aggression in modern society. There are a number of social and environmental factors, attributable to increasing narcissism in modern society. Among them, change in parenting practices, and parent-child relationships, is likely to have affected increase in narcissism in terms of personality development. In conclusion, when treating patients exhibiting aggression in psychotherapy, it is critical to fully consider the possibility of pathological narcissism and its use in analysis.
