The contextual subjective well-being (SWB) of context-aware system users can be very helpful in recommending relevant mental health services, especially for those who struggle with mental illness due to a metabolic syndrome or melancholia. Self-surveying measuring or auto-sensing methods have been suggested to monitor users' SWB. However, self-surveying measuring method is not inappropriate for a context-aware service due to requesting personal data in a manual and hence obtrusive manner. Moreover, auto-sensing methods still suffer from accuracy problem to be applied in mental health services. Hence, the purpose of this paper is to propose a contextual SWB estimation method to estimate the user's mental health in unobtrusive and accurate manners. This method is timely in that it acquires context data from the user's literal responses, which expose their temporal feeling. In particular, we developed a measuring method based on exposed feeling verbs and degree adverbs in chat and other text-based communications which show anger or negative feelings. Based on the proposed contextual SWB degree estimation method, we developed an idea of well-being life care recommendation. From the experiment with actual drivers, we demonstrated that the proposed method accurately estimate the user's degree of negative feelings even though it does not require a self-survey.

Objective：This study was performed to identify and understand the characteristics of adolescents who had a history of police arrest and/or were adjudicated unruly/delinquent by the juvenile court. Method：The study employed a retrospective reivew of coumputer-recorded data set on 210 consecutive admissions to an adolescent psychiatric inpatient unit. Three groups(No Police Contact, N=115；Police Contact Only, N=60；Adjudicated, N=35) were compared on the areas of a) cognitive and educational performance b) emotion：anxiety, depression, suicidality c) personality d) family and life experiences. Standardized assessments were administered to all subjects using WISC-Ⅲ, Kaufman Test of Educational Achievement, Millon Adolescent Personality Inventory, Reynolds Adolescent Depression Scale, Revised-Chilren’s Manifest Anxiety Scale, Suicide Ideation Questionnarie, Suicide Behavior Interive, Life Events Checklist, and Family Environmental Scale. A subgroup of the subjects, 60 cases also received a standardized interview by Child Assessment Schedule. Results：The characteristic findings of the delinquent group(the police contact only and adjudicated subjects combined) included (1) a high rate of adoption, sexual promiscuity, out of home placement, and repeated psychiatric hospitalization, (2) low verbal IQ scores and educational achievements, (3) high impulsivity, low social conformity, and high forcefulness in personality inventory, (4) low activityrecreation orientation and low moral religious emphasis in family environment, (5)a high frequency of adverse life experiences, (6) among 3 groups, the Police Contact Only group showed the lowest depression, anxiety and suicidal ideation scores, (7) a high diagnostic frequency of conduct disorder, ODD, and ADHD. Conclusions：The adolescent psychiatric inpatients with a delinquent history presented with a certain clinical, family, psychometric characteristics that warrant specific clinical intervention strategies for their cognitive deficits, an impulsive personality style, family dysfunction with adverse life experiences and disruptive behavioral disorders, different from the rest of adolescent psychiatric inpatients.

This study was to investigate whether there are differences in subjective bad breath-related characteristics and psychological characteristics of sports masks printed with natural minerals compared with quarantine masks and cotton masks. The study subjects were divided into 30 people in the Sports Mask Group, 30 people in the KF Mask Group (KMG), and 30 people in the cotton mask group (CMG), and a total of 90 subjects participated in the study. It was randomly sent to use 1 mask per day and 3 masks for 3 days. The study period was conducted from October 15, 2020 to October 30, 2020. As a result of the study, there was no difference in the use of masks between the three groups in terms of bad breath health and dry mouth. However, the sports mask was superior to other masks in oral respiration and bad breath angle. As a result of analyzing psychological factors, there was no difference between the 3 groups for depression. However, in the stress factor, sports masks were superior to other masks in stress. The results of this study are valuable as suggesting the direction of use of functional masks, and we hope that they will be used as basic data for functional mask research to be studied in the future.

Objectives : "Alexithymia" mean literally "no word for mood(or emotion)". It is not only a marked constriction in emotional functioning but a deficit in their cognitive processing. We designed this study to investigate the level of alexithymia, psychopathology and personality factors of patients with somatoform disorder and with diabetes mellitus. Methods : The subjects were consisted of patients with somatoform disorder(N=20), patients with diabetes mellitus(N=20), and normal control(N=20). The level of alexithymia, psychopathology and personality factors were assessed by the Toronto Alexithymia Scale(TAS), the Symptom Checklist 90-Revision(SCL 90-R), and the Sixteen Personality Factor Questionnaire(16-PF). And we compared demographic characteristics, psychopathology and personality factors among three groups, and assessed the relationship between alexithymia and psychopathology, and between alexithymia and personality factors. Results : The results were as follows. 1) Patients with somatoform disorder showed significantly higher TAS scores compared to patients with diabetes mellitus and the normal control group. 2) Patients With somatoform disorder showed significantly higher scores of somatization, anxiety scales than patients with diabetes mellitus and the normal control group, and showed significantly higher scores of obsessive-compulsive, depression, phobic anxiety, psychoticism scales than the normal control group by the SCL-90-R. 3) The normal control group showed high intelligence scores only as compared to patients with somatoform disorder by the 16-PF. 4) A significant relationship was found between TAS scores and psychopathology in patients with somatoform disorder. 5) All three groups did not shown any correlation between TAS and 16-PF. Conclusion : Patients with somatoform disorder showed higher TAS scores and more multiple psychopathology than patients with diabetes mellitus and the normal controls. A significant relationship was found between TAS scores and psychopathology in patients with somatoform disorder. We suggest that the therapeutic approach to patients with somatoform disorder to express emotions and manage psychopathology, and that the treatment methods of patients with diabetes mellitus aims to improve firstly physical conditions are more helpful.

This study was performed to assess the effects of physiological factors and lifestyles on bone mineral density (BMD) in 64 postmenopausal women. Sixty four subjects were selected out of 223 postmenopausal women in Seoul and Kyunggido. The BMD of the lumbar spine (L2 ${\rightarrow}$ L4) and femoral neck were measured dual energy X-ray absorptiometry (DEXA). Subjects were assigned to one of three groups such as normal (T-score > -1, n = 20), osteopenia (-2.5 < Tscore ${\leq}$ -1, n = 24), and osteoporosis (T-score ${\leq}$ -2.5, n = 20). Anthropometric measurements and questionares were administered to these women. The mean age, height, weight and BMI were 62.09 yrs, 153.78 cm, 56.09 kg and 23.70 $kg/m^2$ respectively. The BMDs of lumbar spines (L2 ${\rightarrow}$ L4), femoral neck were 0.84 $g/cm^2$, 0.71 $g/cm^2$ respectively. Years after menopause and age of last delivery of the osteoporosis and osteopenia group were significantly longer than the normal group (p < 0.05). The hours of exercise and outdoor activity of the normal group were longer than the osteoporosis and osteopenia group, but there were no significant differences among the three groups. The BMDs of these two sites were positively correlated with weight, BMI, hip and body fat and negatively correlated with LBM, TBW. These results show there are no consistent effects on bone mineral density, adjusting for age and BMI, of physiological factors and lifestyles in postmenopausal women. Therefore. this study confirmed that one of the most effective ways to minimize bone loss in postmenopausal women would be to maintain an adequate body weight.

Recently, Korean prefer the slim and skinny body. Even though they are normal or underweight, they strive for weight control routinely. Due to the appearance-oriented trend prevalent in our society, severe losing weight for women has become a social problem. The purpose of this study is to examine the relationship between body dysmorphic disorder and depression. Health-related and health-unrelated college students were classified into three different groups according to BMI. This study was performed of 200 health-related and 200 health-unrelated college students respectively at K college in Gangwon province. A self-administered survey was conducted from September 10 to 21, 2012, and the 319 questionnaires were analyzed. The collected data were analyzed by the SPSS(statistical package for the social science) WIN 18.0. Regarding the relationship between the BMI of the female students and their unsatisfied parts of the body, the overweight female students were more dissatisfied with the entire lower parts of their body(${\chi}^2$=6.97, p<.05). About the waist and belly, the female students of normal weight were the most dissatisfied but of under weight were less dissatisfied than the other groups and the differences among them were statistically significant(${\chi}^2$=8.12, p<.05). About the chest and breasts, the female students of under weight were more dissatisfied than the other groups and there were significant differences according to BMI. As a result of analyzing the relationship between the BMI of the female students and their dissatisfied parts of the body, the female students of over weight were more dissatisfied with the entire lower parts of their body and whole body, and the female students of normal weight were more dissatisfied with their waist and belly than the other groups. The female students of under weight were more dissatisfied with their chest and breasts. But, there were no differences in the way they want to try for a change of the dissatisfied part of the body. Because this body dysmorphic disorder may be associated with depression and cause the social and cultural problems, the development of counseling programs and additional research should be needed.

Objectives：Conduct disorder is one of the most frequent diagnosis in outpatient and inpatient mental health facilities for children and adolescents. This study investigated the clinical characteristics of children and adolescents with conduct disorder. Methods：The study employed a retrospective review of 45 inpatients diagnosed with conduct disorder by DSM-IV criteria at SNUH Child Psychiatric Unit from 1993, March to 1998, September. Results：The results were as follows：1) The sex ratio was 2：1, male dominant. Mean age on admission was $12.8{\pm}2.4$ years old(male：$12.2{\pm}2.3$, female：$14.1{\pm}2.1$). The mean age of male subjects was significantly lower than that of female subjects(p<.05). 2) We classified all subjects according to child- or adolescent-onset type by DSM-Ⅳ. Childhoodonset type was 42.2%, and adolescent-onset, 57.8%. The onset of male subjects were significantly earlier than that of female subjects(p<.05). 3) The most common complaint was 'serious violation of rules'(77.8%) by DSM-Ⅳ dimensions, while the most common single symtom was 'run away from home overnight at least twice while living in parental or parental surrogate home'(48.9%). 4) The comorbid psychopathology of the subjects were frequently described as follows, in order of frequency：substance use(42.2%), ADHD(35.6%), depression(20.0%), tic disorder(11.1%), bipolar disorder(4.4%). 5) On MMPI, both Pd and Ma subscales got the highest scores. The mean of total IQ by KEDIWISC was $100.0{\pm}15.1$. Female subjects' IQ was higher than that of male subjects. 6) Regarding the number of visits to the OPD after discharge, many subjects(33.3%) had visited OPD fewer than four times. Conclusions：In this study, the male to female ratio of adolescent type showed a decreasing trend. An interesting finding was the fact that socio-economic circumstances, as well as the level of education among patients, were higher than those of previous studies. The subjects' problem were also principally self contered and posed no threat to others.

Objective: The purpose of this study was to identify the correlates of bone mineral density of Korean adults. Methods: This study was based on the data from the 2010-2011 Korean National Health and Nutrition Examination Survey (KNHANES, 2010~2011) V. Among 8,473 subjects of the survey, who were adults 19 years old or over with bone mineral density data, the current study excluded those whose data include a missing study variable or the response of 'I don't know', and finally analyzed the data of 5,986 subjects (2,692 males and 3,294 females). This study employed the following statistical methods of analysis: t-test, analysis of variance (ANOVA), and hierarchical multivariate linear regression analysis. Results: In multivariate analysis, in the case of men, the significant associated factors in bone mineral density were age, education level, body mass index (BMI), waist circumference, total muscle mass, exercise, and weight control; in the case of women, the significant associated factors in bone mineral density were age, education level, economic activity, BMI, total muscle mass, exercise, weight control. fat intake, uptake female hormone, menopause, and age of menarche. Conclusion: For both sexes, the strongest modifiable factor in influencing bone mineral density was total muscle mass. Therefore, to prevent osteoporosis and promote health, active health education and interventions such as regular exercise for total muscle mass increase should be implemented from an early growth period.

Objectives : The purposes of this study were to estimate the prevalence rate of eating disorders in Korean males and to clarify their characteristics in sociodemograhic data, the eating traits, and general psychopathology through the comparison with those of female high scored group on the Korean version of Eating Attitudes Test-26(KEAT-26). Methods : Using a multi-stage questionnaire sampling method including area sampling, proportionated stratified sampling, and quota sampling, we surveyed a total of 4,400 Korean adults over 18 in a nationwide area(9 kus, 10 middle or small cities, and 17 kuns), obtaining usable responses on 3,896. Of the 3,062 subjects(1249 males and 1813 females) who were available for analysis, we ascertained 52 males and 208 females who had high score($\geq$ cutoff point 21) on the KEAT-26. Results : 1) The proportion of this high score group was 1.7% in male and 6.8% in female with a sex ratio(male versus female) of 1 : 4. 2) The mean age was higher in the male group than in the female group, although it was not statistically significant(p=0.0514). Mean Body Mass Index(BMI) of the male group was significantly higher than that of female group, and the number of male subjects with below 20 of BMI was also significantly lower than in the female group. 3) There were no significant difference in past history of physical illness between two groups. However, frequency of smoking and alcohol use, and mean amount of alcohol consumption per month were significantly higher in the male group than in the female group. There were no significant differences between the two groups on various socio-demographic correlates such as economic status, total duration of education, number of family, marital status, religious status, and area of residence, but the exception of being occupational status. 4) The 'Eating Habits Scale' score and score of 'preference for vegetables and fish, and dislike for sweet-tasting food' of the male group were significantly lower than those of the female group. Although there was no significant difference between the two groups in total scores of the KEAT-26, the mean score on 'pursuit of thinness' subscale was higher in the female group than in the male group, while scores of 'food preoccupation' and 'self-control' subscales were higher in the male group than in the female group. 5) Scores on 'psychoticism' was significantly higher in the male group than in the female group, although there were no significant differences between the two groups on 'locus of control for weight', 'depression' and 'hypochondriasis'. Conclusion : These results support a possibility of a high prevalence of eating disorders in Korean males. These results suggest that eating related characteristics of high scorer on the EAT are different by sex in spite of the same high score on the EAT, and also suggest that male patients with eating disorders have more serious personality pathology than female patients with eating disorders.
