Burning mouth syndrome (BMS) is defined as burning pain in the tongue or other oral mucous membrane associated with normal sign and laboratory findings at least 4 to 6 months. There are many factors that affect this condition and the pain characters are various among the sufferers, so it is difficult to diagnose exactly and treat properly. The cause of BMS is currently unknown. The etiology is presumed to be that it is related with local, systemic and psychogenic factor. The BMS is related with local factor such as allergic reaction, oral fungal infection(candidiasis), parafunctional oral habits and systemic factors such as diabetes mellitus, hypothyroidism, nutritional deficiencies(vitamin $B_{12}$, folic acid), hyposalivation and psychogenic factor such as depression, anxiety, cancerphobia. So clinicians must be aware of these factors and can give proper treatment options to patients. The management of BMS are pharmacologic management, cognitive behavioral therapy and psychotherapy treatment. Clonazepam, gabapentin, amitriptyline, alpha-lipoic acid and capsaicin are used to manage the BMS. Among these, topical clonazepam is reported that the effect is higher than systemic medication and the complications are rare. This case report is about some cases of the effect of topical clonazepam on BMS.

There has been an increase in head trauma due to rapid industralization and improvement in transportation. This poses difficulties in differentiating between neuropsychiatric disabilities resulting from real organic changes and those arising from compensation issues. It is the purpose of this study to seek out the differences between normal and abnormal finding group in the structural brain imaging studies via the results of the functional brain imaging studies and psychological tests. Out of 132 subjects, 62 comprised normal and 70 the abnormal finding group. EEG and SPECT were chosen for inspection of functional brain imaging. MMPI and K-WAIS were chosen for psychological test. The subjects were further divided into right hemispheric damage, left hemispheric damage, both hemispheric damage, diffuse damage group and negative group in order to find out whether any differences in the psychological lest results could be localized. The results are as follows : 1) The abnormal finding group, the EEG and SPECT were proven to be a good predictor of brain lesion. This implies that even in the functional brain studies, abnormalities are more easily detected if there are visible brain lesions. 2) The FSIQ of the abnormal finding group is lower than that of normal finding group. this difference is mainly due to low V1Q. The left hemispheric damage group lend to shaw low V1Q. This lowered in was the difference between left hemispheric damage group and negative group. Furthermore, there were no group differences in the PIQ. It is concluded that K-WAIS is effective as evaluator of VIQ mainly of those patients with left hemispheric damage and it is ineffective as a evaluator of PIQ. 3) In the MMPI profile, the both groups displayed high neurotic profiles. There was no difference in the psychotic profiles. The scores of the Depression and Hystery were high in abnormal finding group. This can be seen as one of the lypical findings of chronic head trauma patients. 4) The abnormal finding group tend to be diagnosed as organic mental disorder in the psychological tests more frequently.

The purpose of this study was to investigate the usefulness of the cognitive function test tool in the clinical or multi-life environment for the elderly and high-risk demented subjects after the development of the non-clinical dementia early diagnosis test content(Co-Wis) based on the contents of the International Clinical Data Standard(CDISC TAUG-Alzheimer's v 2.0, SDTMIG v3.3) And to verify the validity and reliability of the data. To do this, after searching for dementia diagnosis process, we developed a non-clinical dementia diagnosis content(Co-Wis) that can supplement the shortcomings of the existing paper test. We selected 30 subjects from elders who were over 60 years old and verified the validity of test and the reliability of retest among cognitive domains of the Korean MMSE-K, Seoul Neuropsychological Test(SNSB-II) and non-medication dementia diagnosis content(Co-Wis). As a result, we showed high correlation and reliability in all cognitive domains. However, the limitations of insufficient subjects and regional distribution were identified. Based on the results of the study, we discussed the necessity of supplementing and expanding further studies such as various methods of verifying validity and reliability.

The research has sought to examine the effect of cognition training using smart device application games on the cognition function of traumatic brain injury patients. The research was conducted to the seventeen traumatic brain injury patients with slight symptoms who were treated with occupational therapy. The patients were divided into the two groups, nine for the experimental group and eight for the control group. The experimental group was assigned to conduct cognition training using smart device application games and traditional cognition training for fifteen minutes each, and the control group has conducted the traditional cognition training for 30 minutes. All arbitrations were conducted for 30 minutes a day, five times a week and for four weeks. To assess the cognitive function, Korean Mini-Mental State Examination (K-MMSE), Lowenstein Occupational Therapy Cognitive Assessment (LOTCA) and visual memory 1 and 2 of Motor-free Visual Perception Test-3 (MVPT-3) were measured before and after the intervention. In the comparison of the change between the two groups, the experimental groups showed a significant improvement in the visual memory of Motor-free Visual Perception Test-3 and remembrance section of the Korean Mini-Mental State Examination (p<.05). The result of this research has confirmed that the cognition training using the smart device application game can make the positive change to the visual memory of the traumatic brain injury patients more than the traditional cognition training.

Prediction of a stock price has been a subject of interest for a long time in financial markets, and thus, many studies have been conducted in various directions. As the efficient market hypothesis introduced in the 1970s acquired supports, it came to be the majority opinion that it was impossible to predict stock prices. However, recent advances in predictive models have led to new attempts to predict the future prices. Here, we summarize past studies on the price prediction by evaluation measures, and predict the direction of stock prices of Samsung Electronics, LG Chem, and NAVER by applying various machine learning models. In addition to widely used technical indicator variables, accounting indicators such as Price Earning Ratio and Price Book-value Ratio and outputs of the hidden Markov Model are used as predictors. From the results of our analysis, we conclude that no models show significantly better accuracy and it is not possible to predict the direction of stock prices with models used. Considering that the models with extra predictors show relatively high test accuracy, we may expect the possibility of a meaningful improvement in prediction accuracy if proper variables that reflect the opinions and sentiments of investors would be utilized.

The purpose of this study was to explore integrated approaches to physical education in general education by examining methodology of physical education aiming for convergence education. This case study was conducted, using a qualitative approach during March, 2017 to November, 2017. Data were collected through non-participant observation, in-depth interviews, field-notes, students' journal, syllabus and lecture materials. The key findings are as follows: First, "Emotion Coaching through Movement" is a course of 'understanding of body' approaching integrated humanities science and natural science. Second, it is a convergence education, conducting 'text to daily practice' by approaching positive psychology and neurophysiology. Third, it is a physical education with 'integrated theory and practice' in higher education. These results indicate that students can understand their own body, observe their daily and fixed movement or reaction pattern, and enhance the ability of understanding others through a physical education in general education.

Objectives : This study was designed to compare the demographic data, clinical characteristics, developmental delay, and psychological tests between childhood-onset and adolescent-onset schizophrenic in-patients. Methods Medical records of the 17 childhood-onset (very early onset) Schizophrenia and 16 adolescent-onset (early onset) Schizophrenia in-patients were reviewed. Sex, age, psychiatric past history, prodromal symptoms and period, subtype, co-morbid disease, developmental delay, prescribed drug and dosage, treatment response, intelligence quotient (IQ), and Rorschach test were evaluated. Results : The mean admission age of childhood-onset (very early onset) group and adolescent-onset (early onset) group were 12.69$({\pm}2.34)$ and 15.13$({\pm}1.04)$ years. The mean onset age of childhood-onset(very early onset) group and adolescent-onset (early onset) group were 10.79$({\pm}1.95)$ and 14.46$({\pm}0.82)$ years. The mean prodromal period of childhood-onset (very early onset) group and adolescent-onset (early onset) group were 15.94$({\pm}12.33)$ and 8.06$({\pm}6.10)$ month. The time to remission period of childhood-onset (very early onset) group and adolescent-onset (early onset) group were 50.58$({\pm}24.67)$ and 30.06$({\pm}18.04)$ days. Longer time to remission period in childhood-osnet (very early onset) group was associated with earlier age of onset. The mean of total IQ, performance IQ, verbal IQ were at an average level. Discussion : Childhood-onset (very early onset) group and adolescent-onset (early onset) group Schizophrenia had different clinical and psychological features including prodromal period, and IQ subtests.

Objectives : The aim of this study was to examine the developmental and clinical characteristics associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed a parent questionnaire consisting of a Child Behavior Checklist(CBCL). Data related to the prenatal, perinatal and developmental history, past and current medical history were collected. Ninety-three normal students were selected as the control group. Results : The nocturnal enuresis group attained diurnal and nocturnal urinary control significantly later than those in the normal control group.49.2% of the children with nocturnal enuresis had the family history of nocturnal enuresis. Daytime incontinence was present in 41.3% of the nocturnal enuresis group. The percentages of sleep-related disturbances were significantly higher in the nocturnal enuresis group when compared to the normal control group.42.6% of the children with nocturnal enuresis experienced pharmacotherapy, and 0.4% experienced enuresis alarms. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have a high genetic load and a possibility of developmental delay, which supports the neurodevelopmental point of view with regard to the etiology of nocturnal enuresis. The physicians in Korea prefer pharmacological interventions to alarm interventions in treating Korean children with nocturnal enuresis.

Objectives: Sleep disturbance in the elderly is associated with cognitive decline. Sleep quality is known to deteriorate with age, and prospective studies seldom have examined the relationship between sleep quality and cognitive function. This study investigates the relationship between early sleep quality and cognitive function based on six-year follow-up data of community individuals older than 60 years. Methods: The participants included 622 community elderly people older than 60 years from Jinju-Si. The final analysis comprised 322 elderly people. Pittsburgh sleep quality index (PSQI) and the Korean version of Consortium to Establish a Registry for Alzheimer's Disease (CERAD-K) were used to assess early sleep quality and cognitive function after six years. Multiple linear regression analysis was performed to investigate the association between early sleep quality and cognitive function in the elderly. Results: Early sleep quality (PSQI) was significantly associated with the results of the digit span test, clock drawing test (clox 1), and word recall test after six years. Sleep quality (PSQI) decreased significantly after six years, and lower quality of sleep (PSQI) score was associated with higher digit span test score (β = -0.167, p = 0.026) and higher clock drawing test score (β = -0.157, p = 0.031). Lower quality of sleep (PSQI) score was associated with higher word recall test (β = -0.140, p = 0.039). Conclusion: The digit span test, word recall test, and clock drawing task (CLOX 1) shown to be significantly associated to sleep quality can be performed fast and easily in clinical practice. It is important to assess early cognitive function in the elderly with poor sleep quality, and further studies could suggest that these tests may be useful screening tests for early dementia in elderly with poor sleep quality.

This study aimed to develop the Korean tool of competency to consent to psychiatric treatment and to analyze the reliability and validity of this tool. Also the developed tool's efficiency in determining whether a patient possesses treatment consent competence was checked using the Receiver Operating Characteristic curve and the relevant indices. A total of 193 patients with mental illness, who were hospitalized in a mental hospital or were in community mental health center, participated in this study. We administered a questionnaire consisting of 14 questions concerning understanding, appreciation, reasoning ability, and expression of a choice to the subjects. To investigate the validity of the tool, we conducted the K-MMSE, insight test, estimated IQ, and BPRS. The tool's reliability and usefulness were examined via Cronbach's alpha, ICC, and ROC analysis, and criterion related validation was performed. This tool showed that internal consistency and agreement between raters was relatively high(ICC .80~.98, Cronbach's alpha .56~.83)and the confirmatory factor analysis for constructive validation showed that the tool was valid. Also, estimated IQ, and MMSE were significantly correlated to understanding, appreciation, expression of a choice, and reasoning ability. However, the BPRS did not show significant correlation with any subcompetences. In ROC analysis, full scale cutoff score 18.5 was suggested. Subscale cutoff scores were understanding 4.5, appreciation 8.5, reasoning ability 3.5, and expression of a choice 0.5. These results suggest that this assessment tool is reliable, valid and efficient diagnostically. Finally, limitations and implications of this study were discussed.
