Effect of Application over Time for Each Type of Blending Tea on Bovine Tooth Coloration / 치위생과학회지

Background@#This study aimed to investigate the effect of selecting commercially available blending teas and applying them to bovine teeth on color change over time. @*Methods@#After selecting healthy bovine teeth, using a cutting-disc, 105 specimens with a dimension of 5×5×3 mm were prepared, and 15 specimens were distributed to each group. Black tea was used as a positive control, water was used as a negative control, and blended tea of five types was used as an experimental group. First, pH and buffering capacity were measured with a pH meter, and tooth color was determined using a spectrophotometer before immersion in the blending tea solution and 1, 5, 7, 14, and 21 days after immersion. Thereafter, the shape change of the enamel surface was observed using a scanning electron microscope, and SPSS ver.26 was used to analyze the color change. @*Results@#The average pH of the five blending teas in the experimental group was 3.78, and the pH of group 3 (strawberry rhubarb) was the lowest at 3.22. The pH levels of black tea and water were 5.19 and 7.30, respectively. The buffering capacity was the highest in group 3 at both pH levels of 5.5 and 7.0. The L*a*b* color change according to immersion time was the largest in group 4 (rooibos yellow flower), and the amount of color change was large in black tea and group 4. As a result of observing the enamel surface of bovine teeth, changes in the surface shape were noted in all groups immersed in the experimental solution for 21 days, except for water. @*Conclusion@#There was a significant difference between the experimental groups in terms of color change according to the immersion time, and color and enamel surface changes were observed in black tea and all experimental groups, except for water.

Factors Affecting Sleep Quality of Firefighters / 정신신체의학

OBJECTIVES: Firefighters frequently experience traumatic events, high-tension situations and shift work. Therefore, the prevalence of insomnia of firefighters is higher than one of general population. Not only does the quality of sleep affect the satisfaction of personal life, but it also influences their performance for the public's safety. We investigated which factors affect the quality of sleep of firefighters. METHODS: After personally delivering 120 questionnaires to 3 fire stations, the survey was conducted when the consents were signed. It inquired about alcohol use, smoking, shift work, sleep quality, depression, anxiety, and experience of traumatic events. We then divided the firefighting officers in two groups according to the quality of sleep and compared the variables examined to conduct the logistic regression analyses according to the results. RESULTS: The poor sleeper group reported a higher level of current alcohol consumption, depression, anxiety and experience of traumatic events. Logistic regression analyses showed that the current alcohol intake (Crude odds ratio=3.707, 95% confidence interval=1.288–10.672, p=0.015 ; Adjusted odds ratio=3.288, 95% confidence interval=1.011–10.694, p=0.048) has a significant effect on sleep quality. CONCLUSIONS: Current alcohol consumption, depression, anxiety and experience of traumatic events were respectively associated with sleep quality of firefighters. When all significant factors considered, the current alcohol use was the only statistically significant. To improve the quality of sleep for firefighters, it will be necessary to evaluate alcohol intake, educate the poor sleep quality caused by alcohol, and provide specific interventions to reduce consumption.

The Effect of Mindfulness-Based Cognitive Therapy on Psychiatric Staff / 정신신체의학

OBJECTIVES: Psychiatric staffs may experience excessive work stress, burnout, and reduced job satisfaction in clinical settings. This can increase chances of diminishing their overall working efficiency or having difficulty managing their own mental health. The purpose of this study was to investigate the effect of group mindfulness- based cognitive therapy(MBCT) on job stress, burnout, self-efficacy, resilience, and job satisfaction. METHODS: Twenty eight psychiatric staffs who agreed to participate in the study were included. Self-report questionnaires were used to measure job stress, burnout, resilience, self-efficacy, and job satisfaction. To examine the effects of group MBCT, the scores were compared before and after MBCT. RESULTS: Work stress and burnout scale scores were significantly decreased after group MBCT. Resilience, job satisfaction, and self-efficacy scale scores were significantly increased after group MBCT. CONCLUSIONS: In the current study, group MBCT for psychiatric staffs helped to reduce their work stress and burnout, and, as well, helped to improve resilience, self-efficacy, and job satisfaction. This suggests that, in mental health treatment settings, psychiatric staffs can improve their mental health through group MBCT. Improving mental health of psychiatric staff may also have a positive impact on their patients.

Smart-Phone Addiction, Depression/Anxiety, and Self-Esteem with Attention-Deficit Hyperactivity Disorder in Korean Children

OBJECTIVES: The current study investigated the risk of smartphone addiction among children and adolescents with or without attention-deficit hyperactivity disorder (ADHD), risk of depression, anxiety, and self-esteem using the Smartphone Addiction Scale Proneness, Kovac's Children's Depression Inventory, State-Trait Anxiety Inventory, and Rosenberg Self-Esteem Scale, commonly used in clinical medicine. METHODS: Ninety five students with ADHD who visited psychiatry outpatient clinics completed the questionnaire. At the same time, 592 middle and high school students living in a similar area regardless of ADHD diagnosis, completed the questionnaire as control subjects. RESULTS: Overall, 40.0% of 95 ADHD and 12.8% of 592 control subjects were classified as the smartphone addiction proneness group, 26.3% of the ADHD subjects and 8.3% of the control group were classified as the depression group, and 32.6% of the ADHD subjects and 16.2% of the control group were classified as the anxiety group. Significant differences were observed between the two groups. CONCLUSION: The results of this study suggest that ADHD subjects are more prone to smartphone addiction, becoming depressed or anxious than those in the control group. From this study, we could suggest that students with ADHD are more easily affected by smartphone addiction than normal control subjects. In addition, we might understand how some psychiatric problems like depression, anxiety, and low self-esteem are related to ADHD and smartphone addiction.

The Mental Effects on Child Actors in Playing a Role : Observations on Filming Sites and Interviews with Filming Personnel

This study was conducted to evaluate the psychological changes and influences of child actors depending on their role. First, we met the film producer of Dogani and discussed about the filming condition. Second, we visited filming locations during the filming of Neighborhood, when shooting of parts involving the female child actor was taking place and evaluated the emotional states of the child actor before and after she played her role. Third, we interviewed various people of the movie industry, which included adult actors, directors, a professor of films and broadcasting who was a former child actor and a scriptwriter. In case of the film Dogani, the production crew provided enough care and protection and we concluded that child actors had no psychological sequelae. After interviewing the child actor and visiting filming locations, we confirmed that the child actor was not influenced by playing certain roles. In addition, after interviewing various people related to filming, we thought that child actors might not have psychological sequelae related to the character played. To the best of our knowledge, this is the first study about influences of the playing character for child actors. We concluded that playing certain roles would not have negative effects on child actors.

Efficacy of the Mentalization Improvement Program for Adolescent (MIPAdo) for Enhancement of Mental Health in School Children

OBJECTIVES: Understanding the emotions, thoughts, feelings and behaviors of others, as well as oneself, is part of the mentalizing function. We developed a new school-based community model for mental health, called the Mentalization Improvement Program for Adolescent-Community Model (MIPAdo-CM), based on the concept of mentalization. METHODS: The MIPAdo-CM was composed of 12 sessions and was applied to 403 students in the 2nd grade of a middle school. Every session was conducted after the regular school hours for 6 weeks. After 6 weeks, we compared the endpoint changes of Adolescent Mental Problem Questionnaire-Revised (AMPQ-R), Emotional Empathy Test (EET), Peer Aggression Scale (PAS), Peer Bullying Scale (PBS), School Adjustment Scale (SAS), Test Anxiety Inventory (TAI) and Visual Analogue Scale between the subject and the control group. RESULTS: There was no significant difference between two groups in AMPQ-R, EET, PAS, PBS, SAS, and TAI. On the Visual Analoge Scale, however, students in the trial classes reported more increase in understanding and respect for both others and themselves. CONCLUSION: The efficacy of MIPAdo-CM was subjective improvement of understanding and respect for both others and themselves, erence between two groups in AMPQ-R, Empathy test, To prove objective usefulness of this program, further studies with more structured design will be needed.

Efficacy of the Short Form of Mentalization Improvement Program for Adolescent (MIPAdo) for Enhancement of Mental Health in School Children

A Pilot Study of the Usefulness of Intelligence Test in Assessment of Attention-Deficit Hyperactivity Disorder

OBJECTIVES: We analyzed the usefulness of intelligence test in assessing attention-deficit hyperactivity disorder (ADHD). METHODS: The medical records of 312 patients with ADHD who visited the child psychiatry department in one university hospital in Seoul, Korea, were reviewed. Demographic data and scores on the Korean Wechsler Intelligence Scale for Children-III (K-WISC-III) and Korean-Conners' Parent Rating Scale (K-CPRS) were analyzed. To assess the relationship with comorbidities, ADHD subjects were classified as; externalizing disorders, internalizing disorders, tic disorders, and no comorbidities. RESULTS: Verbal intelligence quotient (VIQ) was significantly higher than performance IQ (PIQ)(102.6+/-14.44, 99.2+/-14.48, p<.001). Using mean scatter method, subtest scores such as 'information, similarities, digit span and coding' were significantly lower than mean scores of sum of subtests of VIQ or PIQ (p<.05). Regarding comorbidities, children with externalizing disorders exhibited. Lower scores on 'information and vocabulary' than other groups (p=.008). Children with no comorbidities exhibited higher scores on 'similarities and object assembly' than children with externalizing/internalizing disorders (p=.001) and also on 'comprehension' than children with externalizing disorders (p=.006). For subtypes of ADHD, children with hyperactive-impulsive type had higher scores on 'comprehension' than children with inattentive and combined type (p=.004). CONCLUSION: These results suggested that intelligence test might provide useful information for assessing ADHD.
