A psychogenic seizure is a disorder which is occasionally met by neurologists and psychiatrists. The most important thing that clinicians should do is differential diagnosis with true epileptic seizures. Especially psychiatrists are expected to be able to diagnose psychogenic seizures through a thorough history taking and an observation of clinical features to some degree before the confirmatory diagnoses. We experienced a case of 11-year-old girl with psychogenic seizure which was characterized by obvious psychological and environmental stress, clinical features, and good outcome by prompt a loboratoy examination and psychiatric intervention. To diagnose and treat childhood psychogenic seizures, we suggest that it is very important to examine the familial background and take a thorough history, and perform psychoeducational intervention in addition to electroencephalogram.

In this paper, the bio-signals, such as EEG, ECG were measured with a sensor and their characters were drawn out and analyzed. With results from the analysis, four emotion of rest, concentration, tension and depression were inferred. In order to assess one's emotion, the characteristic vectors were drawn out by applying various ways, including the frequency analysis of the bio-signals like the measured EEG and HRV. RBFN, a neural network of the complex structure of unsupervised and supervised learning, was applied to classify and infer the deducted information. Through experiments, the system suggested in this thesis showed better capability to classify and infer than other systems using a different neural network. As follow-up research tasks, the recognizance rate of the measured bio-signals should be improved. Also, the technology which can be applied to the wired or wireless sensor measuring the bio-signals more easily and to wearable computing should be developed.

Objectives: The purpose of this study was to examine the performance and electrophysiological characteristics of drug-naive children with attention-deficit/hyperactivity disorder(ADHD) during the Go/NoGo task. Methods: Twenty-three boys with ADHD and 18 age-matched normal boys were recruited at a child psychiatric outpatient clinic in Seoul. All subjects were assessed by the Kiddie Schedules for Affective Disorders and Schizophrenia Present and Lifetime version. The investigator also assessed all subjects using the ADHD Rating Scale-IV(ADHDRS). Event-related potentials were recorded from 8 scalp electrodes during the visual Go/NoGo task. Results: Children with ADHD showed a larger mean of standard deviation of response time during the Go/NoGo task than normal children. The temporal N200 and P300 amplitudes were larger in children with ADHD relative to controls. The parietal N200 and P300 latencies were more prolonged in children with ADHD compared to normal controls. Conclusion: These results suggest that psychotropic-naive children with ADHD may have more variable performance ability, more difficulty in discriminating visual stimuli, and slower information processing speed than their normal age-matched counterparts.

This research examines 240 patients who visited a center a specific city, between July-September 2017. Subjects underwent body composition analysis and brainwave measurements, and were subsequently divided into groups according to BMI and body fat percentage. These patients were measured by timeseries linear analysis for their brain function and observed via brainwave activities. Results of the research are as follows: there is a difference in stress-resistance between obese and those in the healthy weight range. This implies there is a causal relationship between stress and obesity. In addition, the methodology used in this study, which is a scientific and objective physiological indicator of a scientific and objective physiological index, suggests that the results of the study are reliable. Results support that managing stress moderates obesity-related problems.

The purpose of this study is to investigate the determinants of the SNS usage time depending on SNS motive of the youth workers. Although previous studies revealed that there are many motivations for SNS usage, it is not known which factors determine usage time of each SNS motive. In this study, we constructed the unbalanced panel data of the Korean Education & Employment Panel data. Among three different SNS motives such as information exchange, social networking, and fun pursuit, gender, physical health, extraversion, and conscientiousness affected the usage of SNS when the motivation was information exchange. When it was personal connection, the size of organization, education, physical health, subjective happiness, job satisfaction, neuroticism, and agreeableness did. When it was fun & interest, foreign company, status of children, subjective happiness, and job satisfaction did. Based on the findings, we discussed theoretical and practical implications.

The purpose of this study was to investigate the effects of early cognitive training and tailored telephone coaching program for ischemic stroke. Among 28 participants, assigned into the experimental(n=15) and control group(n=13). Only the experimental group was received a 4-week cognitive training and 11 session of tailored telephone coaching. The effect ot the program was evaluated four times(baseline, 4weeks, 8weeks, 12months) using the tool on Depression, Mini Mental State Examination(MMSE), Neuropsychological battery, Activities of Daily Living(ADL). The repeated measures ANOVA showed that the experimental group showed improvement in MMSE, verbal memory and executive function compared to the control group. Especially, the improvement of executive function which is related to ADL was a remarkable result. This suggests that early intervention is very important for recovery cognitive function and independent daliy life after stroke, and periodic telephone coaching should be done together for mid-to long term effects.

Maxillary duplication is a kind of proliferative neurocristopathy and considered to arise from bifurcation of neural crest elements soon after migration into mandibular arch. Sometimes this malformation is accompanied with oblique facial cleft. Usually this type of maxillofacial malformation requires multiple surgical intervention and the results are far from ideal. It became more troublesome if it had not been properly corrected on time, because secondary deformities could be developed from growth and development of abnormal tissues. This is a case of a 25-year-old-female patient who showed severe facial asymmetry thought to secondary deformity of maxillary duplication and masticatory disturbance due to multiple supernumerary teeth on posterior part right maxilla. We successully treated these deformities through four times of surgery of bone resection, orthodontic treatment, zygomatic and orbital reconstruction, orthognathic surgery and scar revision... ect. So we reported this rare case with review of literatures.

Lexical ambiguity means that a word can be interpreted as two or more meanings, such as homonym and polysemy, and there are many cases of word sense ambiguation in words expressing emotions. In terms of projecting human psychology, these words convey specific and rich contexts, resulting in lexical ambiguity. In this study, we propose an emotional classification model that disambiguate word sense using bidirectional LSTM. It is based on the assumption that if the information of the surrounding context is fully reflected, the problem of lexical ambiguity can be solved and the emotions that the sentence wants to express can be expressed as one. Bidirectional LSTM is an algorithm that is frequently used in the field of natural language processing research requiring contextual information and is also intended to be used in this study to learn context. GloVe embedding is used as the embedding layer of this research model, and the performance of this model was verified compared to the model applied with LSTM and RNN algorithms. Such a framework could contribute to various fields, including marketing, which could connect the emotions of SNS users to their desire for consumption.

In the paper. we propose an evaluation model based the adaptive fuzzy systems, which can transform the physical features of a color pattern to the emotional features. The model is motivated by the Soen's psychological experiments, in which he found the physical features such as average hue, saturation, intensity and the dynamic components of the color patterns affects to the emotional features represented by a pair of adjective words having the opposite meanings. Our proposed model consists of two adaptive fuzzy rule-bases and the y-model, a l i r ~ r ys et operator, to fuze the evaluation values produced by them. The model shows con~parablep erformances to the neural network for the approximation of the nonlinear transforms, and it has the advantage to obtain the linbwistic interpretation from the trained results. We believe the evaluated results of a color pattern can be used to the emotion-based color image retrievals.

The results of this study showed that victim's job motivation, organizational distrust, nervousness, turnover intention, frustration, stress and resistance, powerlessness and alienation were similar to previous studies. I was overwhelmed by the negative force of the collective union and experienced anger in the reality that one individual could not resist or find a solution. In addition, psychological factors such as union members' fear of union bullying were found to have a positive effect on the union members who did not join the strike and those who did not join the strike. It is necessary to consider the question of whether the group bullying behavior is valid in that the union bullying behavior of the union is effective in achieving the purpose of the group.
