  • In this paper, we present electroencephalography (EEG)-based power spectra analysis and auditory stimuli methods as coping mechanisms for disgust affection and phobia. Disgust affection is a negative emotion generated from trying to eliminate something harmful to one. It is usually related to mental illnesses such as obsessive-compulsive disorder, specifically phobia and depression. In our experiments, participants watched videos on horrible body mutilation and disgusting creatures, with either the original sound track or relaxing and exciting music as auditory stimulation. After watching the videos with original sound track, the participants watched the same video with a different audio background, such as soothing or cheerful music. We analyzed the EEG data utilizing relative power spectra and examined survey results of the participants. The results demonstrated that disgust affection is decreased when participants watched the video with relaxing or exciting music instead of the original soundtracks. Moreover, we confirmed that human's brainwave reacts according to types of audio and sources of disgust affection.

  • Recent studies have strongly implicated postsynaptic scaffolding proteins such as SAPAP3 or Shank3 in the pathogenesis of various mood disorders, including autism spectrum disorder, bipolar disorder (BD), and obsessive-compulsive disorders. Neural Abelson-related gene-binding protein 2 (nArgBP2) was originally identified as a protein that interacts with SAPAP3 and Shank3. Recent study shows that the genetic deletion of nArgBP2 in mice leads to manic/bipolar-like behavior resembling symptoms of BD. However, the function of nArgBP2 at synapse, or its connection with the synaptic dysfunctions, is completely unknown. This study provides compelling evidence that nArgBP2 regulates the spine morphogenesis through the activation of Rac1/WAVE/PAK/cofilin pathway, and that its ablation causes a robust and selective inhibition of excitatory synapse formation, by controlling actin dynamics. Our results revealed the underlying mechanism for the synaptic dysfunction caused by nArgBP2 downregulation that associates with analogous human BD. Moreover, since nArgBP2 interacts with key proteins involved in various neuropsychiatric disorders, our finding implies that nArgBP2 could function as a hub linking various etiological factors of different mood disorders.

  • This study investigated the relation between verbal abuse by parents and children's maladjusted emotional behavior. The sampling consisted of 628 children in 16 classes out of every three elementary schools and one middle school. Instruments used for this study were the Verbal Abuse Measure, Parent-to-child violence items of the Conflict Tactics Scales, Emotional Maladjustment Behavior Scale, and Socioeconmic Status. Methods applied to data analysis were multiple regression, logistic regression and logistic curve graphic display. The major findings were ; (1) Of all subjects, almost 20% experienced at least one instance in which they were victims of verbal abuse during the year covered by this study. (2) As the amount of physical abuse by parents increased the verbal abuse by parents increased. The older children experienced more verbal abuse than the younger ones. (3) Verbal abuse by parents was more highly related to maladjusted emotional behavior of the children than physical abuse by parents. (4) Regardless of the physical violence by parents, verbal abuse by parents was associated with maladjusted emotional behavior of children. Children who were subjected to both verbal and physical abuse were more strongly related to withdrawal, hyperactivity, and obsessive-compulsions than children experienced either one or the other.

  • Purpose: This study was to examine the effect of postpartum exercise on mental health. Mental health comprises a 9 symptom dimension of Somatization, Obsessive-Compulsive, Interpersonal Sensitivity, Depression, Anxiety, Hostility, Phobic anxiety, Paranoid Ideation, and Psychoticism. Method: A non-equivalent pre-test, post-test control group study was conducted. Fifty-two puerperal women who were admitted to a postpartum ward of a mother-baby clinic in Pusan were recruited; 26 women were assigned to the experimental group and 26 women to the control group. Postpartum exercise was applied to the experimental group from postpartum day 3 for a period of 8 weeks while no exercise program was applied to the control group. Mental health with SCL-90-R was measured before and after exercise. Data was analyzed using mean, $x^2$-test, t-test, and ANOVA by SPSS 10.0. Result: The mental health status in the exercise group did not show a statistically significant decrease when compared to that of the control group. Conclusion: There is no effect of postpartum exercise on women's mental health during the first 8 weeks of the postpartum period. Further studies are needed for randomized clinical trials with a larger sample size.

  • Lithium is mainly prescribed for manic and depressive disorder, also frequently prescribed for the other diseases such as migraine, cluster headache, alcoholism, and obsessive-compulsive disorder. An acute lithium intoxication occurs in cases of patients ingesting large amount lithium at a time, a chronic lithium intoxication occurs in patients on chronic lithium therapy. Acute or chronic lithium poisoning occurs frequently in case of patients on chronic lithium therapy ingesting larger dose than prescribed. Manifestations of lithium poisoning are various. It is possible nervous, cardiovascular, renal, gastrointestinal and endocrine systems to be involved. Due to intracellular high concentration, mortality rate is high in acute lithium intoxication patients on chronic lithium therapy. We report a case of acutely intoxicated 40-year-old male on chronic lithium therapy. His chief complaints were deterioration and high fever. On his arrival to an emergency department, he was in cardiac arrest. He restored return of spontaneous circultion (ROSC) 5 minutes later after cardiopulmonary cerebral resuscitation (CPCR) and referred to department of internal medicine for hemodialysis. Vigorous treatment was given to the patient, but he was expired at 4th hospital day.

  • Architecture is a product of numerous influences, as shown in the apprenticeships of Kim, Jung-Up and Kim, Swoo-Geun with Le Corbusier's influences. Therefore, its identity is need to be re-defined based on such complex relationships. The rhetorical images of 'the Map of Misreading', as the core of the poetic identification proposed by Harold Bloom's 'the Theory of Influence', provide an efficient way of explaining the relations between architectural apprenticeships and identities. This research is to re-build a new methodology of architectural criticism based on it. The diachronic transformations of the architecture of Seung, Hyo-Sang also had very characteristic 'revisionary ratios' about his precursor Kim, Swoo-Geun. As an antithetic stance of his precursor's final phase, his early days works pursued continuously geometric abstraction and objective images of the architecture of Adolf Loos. However, his recent works are showing the obvious symptoms of regression to his origins. Finally, the architectural identity should be re-conceptualized as a complexity, based on inter-textuality from complex influences. This new architectural identity can be reflected into the modern obsessive identity.

  • Gilles de la Tourette syndrome is a chronic motor and vocal tic disorder of childhood onset. Abnornmalities in basal ganglia-thalamo-cortical circuits may play an important role in the pathophysiology underlying the involuntary tics. It is often complicated by comorbid attention-deficit/hyperactivity disorder or obsessive-compulsive disorder. Transcranial magnetic stimulation(TMS) is a neurophysiologic technique with research ap-plication. As there is good evidence that this technique can modify cortical activity, repetitive TMS is also used for treatment to change the cortical excitability and therefore affect underlying interconnected cortical-sub-cortical loop. We reviewed the neurophysiologic parameters and the clinical applicability of TMS and rTMS.

  • Magnetic resonance-guided focused ultrasound (MRgFUS) is a new emerging neurosurgical procedure applied in a wide range of clinical fields. It can generate high-intensity energy at the focal zone in deep body areas without requiring incision of soft tissues. Although the effectiveness of the focused ultrasound technique had not been recognized because of the skull being a main barrier in the transmission of acoustic energy, the development of hemispheric distribution of ultrasound transducer phased arrays has solved this issue and enabled the performance of true transcranial procedures. Advanced imaging technologies such as magnetic resonance thermometry could enhance the safety of MRgFUS. The current clinical applications of MRgFUS in neurosurgery involve stereotactic ablative treatments for patients with essential tremor, Parkinson's disease, obsessive-compulsive disorder, major depressive disorder, or neuropathic pain. Other potential treatment candidates being examined in ongoing clinical trials include brain tumors, Alzheimer's disease, and epilepsy, based on MRgFUS abilities of thermal ablation and opening the blood-brain barrier. With the development of ultrasound technology to overcome the limitations, MRgFUS is gradually expanding the therapeutic field for intractable neurological disorders and serving as a trail for a promising future in noninvasive and safe neurosurgical care.

  • The importance of human factors has been emphasized for pilots because most of aviation accidents have been caused by the human factors of pilots. Human factors issues such as fatigue affecting flight safety are needed to be educated to student pilots who have less experience in flight training. In order to prevent aviation accidents caused by human factors, the management of stress, fatigue, and obsessive-compulsive disorder which increase psychological harmful factors of student pilots, is essential for aviation safety. The management of fatigue is required as a part of safety management system following the guidance of leading aviation authorities. The purpose of this article was to investigate the factors of fatigue at each stage by classifying it into before, during, and after flight training to manage the fatigue of students pilots. Then, the factors of relatively high fatigue were analyzed by using the AHP process to provide factors related fatigue affecting pilot training.
