Objectives : This study looked at the symptoms of alexithymia in schizophrenia and their association with clinical variables and schizophrenic symptomatology. Methods Consecutive fifty eight inpatients with DSM-IV diagnoses of schizophrenia completed 26item version of Toronto Alexithymia Scale (TAS), Symptom Checklist-90-Revised(SCL-90-R), and Positive and Negative Syndrome Scale(PANSS). Results : Authors did not find any correlation between scores of PANSS and TAS. However, all the subscale scores of SCL-90-R were significantly correlated with total score of TAS. Also, 'difficulty identifying and deistinguishing between feelings and bodily sensations' and 'difficulty describing feelings' significantly correlated with SCL-90-R subscale scores. 'Reduced daydreaming' had mixed findings and 'externally oriented thinking' did not correlate. Multiple regression model included Global Severity Index of SCL-90-R accounting 28.2% of variance for TAS scores. Conclusion : These findings together with discrepancy in results between objective and subjective tests suggest that alexithymia in schizophrenia may have two constructs, 'difficulty to describe and communicate feelings(state)' and 'externally oriented thinking(trait)' Authors suggest further study needs to confirm construct validity of TAS in this population.

Objectives : Many studies have shown an association between serum lipid concentrations and psychologic characteristics. However, conflicting results have also been reported. This study was designed to find the relationship between serum lipid levels(cholesterol and triglycerides) and psychologic characteristics(impulsiveness, aggressiveness, depressiveness) in adolescents. Methods : Serum cholesterol concentration, serum triglycerides concentration, complete blood count, electrolytes, liver function test, and blood sugar level were measured by overnight fasting blood sampling and urinalysis was also conducted in 407 high school students. Impulsiveness level was measured by Barratt Impulsiveness Scale(BIS). Aggressiveness level was measured by Buss-Durkee Hostility Inventory(BDHI). Depressiveness level was measured by Beck Depression Inventory(BDI). Serum cholesterol was measured by standard enzymatic assay and serum triglycerides was measured by Boehringer Mannheim method. Results : 1) Low cholesterol group(<15 percentile) were found to have significantly higher BIS score than high cholesterol group(>85 percentile) in female. Female low cholesterol group were also found to have significantly higher motor impulsivity score, a subscale of BIS, than high cholesterol group. 2) High triglycerides group(>85 percentile) were found to have significantly higher BDI score than low triglycerides group(<15 percentile) in male and female separately. Especially, male high triglycerides group were also found to have significantly higher BIS and motor impulsivity score than low triglycerides group. Conclusion : These results support the previous hypothesis that serum lipid levels(cholesterol and triglycerides) affect human psychologic characteristics.

Background : Various type of psychological and stressful events in life have been reported to have much effect in the onset, progress and exacerbation of psychosomatic disorders such as hypertension, bronchial asthma, peptic ulcer, tension headache, alopecia areata, and atopic dermatitis. However, the nature of the association between stress and psychosomatic disorders remains unclear. Objective : The purpose of this study is to determine the relation of stress and the progress of dermatologic disorder. Method : We examined 30 patients with atopic dermatitis and 30 control subjects with tinea pedis and onychomycosis who visited to Dept. of Dermatology, Chung-Ang University Hospital. To evaluate the stress, we used 'Scale of Life Events' and 'Multidemensional Coping Scale'. Result : 1) The score of life events stress in atopic dermatitis group was significantly higher than that of control group. 2) In the result of coping strategies, the atopic dermatitis group was significantly higher than control group at the active forgetting, positive comparison, and emotional pacification, while in control group religious seeking and accomodation tended to be higher with no statistical significance. Conclusion : These findings suggest that psychosocial stress may play a role in life pattern of atopic dermatitis. But further studies are needed to clarity the exact relationship between stress and psychosomatic disorder.

The purpose of map generalization is a method of map making to transmit the concise cartographic representation and geographic meaning. New generalization algorithm has been developed to be applied in the digital environments by the development of computer cartography. This study aims to look into possibilities of the multiscale mapping by generalization in application with the coordinate transformation and LoD(level of detail) in the web cartography. A method of the coordinate transformation is to improve a transmission of spatial data. Lod is a method which is making web map with selection spatial data by zoom level of users. Layers for test constructed contour line, stream network, the name of a place, a summit of mountain, and administrative office. The generalization was applied to zoom levels by scale for the linear and polygonal features using XML-Based scalable vector graphics(SVG). Resultantly, storage capacity of data was minimized 41% from 9.76mb to 4.08mb in SVG. Generalization of LoD was applied to map elements by stages of the zoom level. In the first stages of zoom level, the main name of places and administrative office, higher order of stream channels, main summit of mountain was represented, and become increase numbers of map elements in the higher levels. Results of this study can help to improve esthetic map and data minimization in web cartography, and also need to make an efforts to research an algorithm on the map generalization over the web.

Effect of water back-flushing period (FT) was investigated in hybrid water treatment process of carbon ultrafiltration and polypropylene (PP) beads coated with photocatalyst, and membrane effect was studied by comparing the previous studies with carbon microfiltration or alumina ultrafiltration, microfiltration membranes. FT 6 min was the most effective to control initial membrane fouling and optimal condition because the membrane fouling resistance was low until initial 60 min and the maximum total permeate volume was acquired at this FT. The turbidity treatment efficiency was high beyond 98.6%, and did not depend on FT, which was same with the previous result of carbon or alumina microfiltration. The organic matters treatment efficiency was the highest value of 98.2% at FT 6 min, which was almost same trend with the previous result of alumina microfiltration. Then the organic matters treatment efficiency of carbon microfiltration was the minimum at no back-flushing (NBF) and increased as decreasing FT, but that of alumina ultrafiltration was the maximum at NBF and also increased as decreasing FT. Therefore it means that water back-flushing effect on the organic matters treatment efficiency had a different mechanism depending on pore size in spite of the same material membranes.

This research was carried out in order to develop and validate the Korean Version of Working Relationship Scale for Mentally Disabled Persons, which measures the working relationship between a mentally disabled person and his or her case manager. The first step taken to develop this scale was to construct sample items for the Working Relationship Scale using literature research and three focus group interviews of mentally disabled persons who use local mental health services. Secondly, mentally disabled people were surveyed with these sample items and two professors from the department of social work who specialize in mental health social work and two licensed mental health social workers working in the community mental health field reviewed these sample items to select and compile a final version of the scale. Lastly, the scale's reliability and validity was verified through an empirical study of 569 mentally disabled persons who surveyed the final selection of items. An explanatory factor analysis showed that the sample items can be grouped into three factors. Factor 1 is 'Professional Contribution Factor,' which is related to the professional practice of the case manager; Factor 2 is 'Negative Working Relationship Factor'; and Factor 3 is 'Emotional Bond Factor,' which measures the intimacy between the case manager and the mentally disabled person. A confirmatory analysis of the three-factor format that was discovered in the explanatory factor analysis was carried out with the rest of the randomly divided data, which showed that the model demonstrated a goodness-of-fit. The convergence validity between similar concepts appeared to be appropriate as well. Based on these results, the Korean Version of Working Relationship Scale for Mentally Disabled Persons consisting of a final 33 items is developed and proposed and its implications in social work are discussed.

Objectives: Symptoms of sleep apnea consisted of insomnia, excessive sleepiness during daytime, impaired cognitive functions and emotional disturbances. It was not so well known how these symptoms are correlated with various parameters of sleep and respiration, and what kind of psychophysiological processes are involved in development of these symptoms. Methods: In sixty patients with sleep apnea, sleep and respiration were studied by polysomnography of one night, also symptoms of sleep apnea were evaluated with the scales of insomnia, daytime sleepiness, emotional disturbance and cognitive impairment We studied correlations between apnea symptoms, and various parameters of sleep and respiration such as sleep efficiency, number severity of apnea, $O_2$ desaturation and number of snoring. Results: The result showing significant correlations are as follows. The patients with better sleep in insomnia scale showed more number of apnea, particularly more central type, and much more snoring in stage 3 sleep and mild desaturation of $O_2$. Excessive sleepiness during daytime correlated significantly with stage 1 sleep and its snoring, but correlated negatively with stage 2 sleep. However, no significant correlation was found with degree of $O_2$ desaturation. Emotional disturbance was more apparent in the patients with severe $O_2$ desaturation and smaller amounts of stage 4 sleep. Cognitive function was more impaired in cases of more REM sleep and less apnea. Conclusions: Symptoms of sleep apnea may occur through different causes and processes. The evaluation of apnea symptoms may be helpful to understand in some degree the condition of sleep and respiration during sleep in clinical setting.

This study aimed to evaluate the relationship of ADHD, depression, anxiety, self-esteem, impulsivity, suicide idea and quality of life as well as burnout of kindergarten teachers for the first time in Korea. Also, it examined the odds ratio with ADHD, depression, anxiety, self-esteem, impulsivity, suicide idea and quality of life between burnout group and the comparison group through logistic regression analysis. A set of questionnaires was provided to a total of 310 participants (80 with higher burnout risk and 230 without burnout risk) from April 2015 to July 2015. All of participants were evaluated using the Korean Adult Attention Deficit Hyperactivity Disorder Scales, Beck's Depression Inventory, Beck's Anxiety Inventory, Baratte' Impulsivity Scale, Rosenberg's Self-esteem Inventory and Qulity of Life Scale. The results of this study indicated that burnout risk group is related to ADHD and anxiety and impulsivity. For the treatment of burnout in kindergarten teachers, effective evaluation and treatment of ADHD and impulsivity, as well as anxiety, seem to be necessary.

Objectives : Loneliness is associated with negative mental and physical health. However, little is known about the risk factors of loneliness in the Korean elderly living alone. The aim of this study was to examine sociodemographic and social network related risks for loneliness among the elderly living alone. Methods : This is a cross-sectional study that enrolled 1,091 subjects who are the community-residing elderly living alone. Sociodemographic status, medical condition, cognition, mood disorder and levels of loneliness were collected using a self-administered questionnaire and a specific semi-structured interview conducted by a trained nurse. Descriptive statistics were used to analyze data regarding sociodemographic variable and loneliness. Univariate and Multivariate regression analyses were applied to examine factors associated with loneliness. Results : The mean score of loneliness was 3.8 (SD=1.7). No family contact (standardized β=0.115, p<0.001), no religious attendance (standardized β=0.057, p=0.028), no gathering with friends (standardized β=0.088, p=0.001) and high score of Short for of Geriatric Depression Scale (standardized β=0.502, p<0.001) were significantly associated with high loneliness in the elderly living alone. Conclusions : Family function, social network and depressive mood could be significant risk factors for high loneliness in the elderly living alone. Public health promotion efforts to reduce loneliness should focus on improving family function, social network and decreasing depression.

Animation is an artificial image created by artist's imagination. Animation is defined as "the art of the animated image" in the sense that immobile images can be seed as a living creature. In other words, the term "diegesis" in modern arts genre is generally considered as something that indicates fictional world in which narration develops. Therefore, when we say that animation world is formed based on diegesis, it represents the fictionality of animation world. The problem occurs at this point. Even thought the animation world is recognized as a fictional world, we contradictorily believe that the event occurring in the screen world are real and accept them as a true message. This condition is called "quasi-emotion". Quasi-emotion is not fake bit not real either, and it is the third emotional state. It happens when we "make believe" that we believe a fictitious figure or a situation. However, in order to actively operate this "make-believe" state, an appropriate environment and props are required, specially metaphorical imagination and storytelling in short animated film. So that this article will draw a conclusion from the method that make-believe the fictional world and communicate the message through analysing the short animate film, form Disney.
