Objectives: The study aimed to identify the characteristics of attention-deficit hyperactivity disorder (ADHD) that was not diagnosed in childhood or adolescence, but only in adulthood. Methods: The characteristics of patients diagnosed with ADHD in adulthood were compared with those of patients diagnosed in childhood were assessed via a retrospective review of the medical records at one university hospital from 2005 to 2013. If the age at which they were confirmed as having ADHD was less than 19 years old, they were grouped as childhood-diagnosed group (CD); if they were 19 years old or more, they were grouped as adulthood-diagnosed group (AD). Results: The CD and AD included 50 (46.3%) and 58 (53.7%) patients, respectively. Inattention was the most common symptom in both groups. Behavioral and emotional problems were the second most frequent symptoms in the CD and AD, respectively. The intelligent quotient was significantly higher in the AD than in the CD. The most common comorbidity was depression in the CD and personality disorder in the AD. The most common reason for visiting the hospital was referral by acquaintances in the CD and media coverage in the AD. Conclusion: Clinicians should put ADHD on the index of suspicion when they examine adults with various psychiatric symptoms, because the diagnosis of ADHD might have been missed in childhood and the symptoms of ADHD might have changed as they grew up.

Objective: The purpose of this study was to investigate the impact of clinical and psychological factors on the self-concept of children and adolescents with epilepsy. Methods: Children and adolescents with epilepsy (n=60; age range=9-17 years) completed questionnaires about their epilepsy-related variables, self-concept, depressive symptoms, anxiety, family functions, and behavioral problems. The T-test and one-way analysis of variance were used to examine the variables affecting the total self-concept scores. To determine the independent variables by adjusting the significant variables, a stepwise regression analysis was performed. Results: In the correlational analysis, age, depressive symptoms, anxiety, social problems, attention problems, and internalizing problems had significantly negative correlations with self-concept. On the other hand, IQ and family functions showed positive correlations with selfconcept. Age (${\beta}=-0.177$, p=0.015), depressive symptoms (${\beta}=-0.487$, p<0.001), anxiety (${\beta}=-0.298$, p=0.008), and attention problems (${\beta}=-0.138$, p=0.048) were analyzed as independent factors to assess their impact on self-concept, and were found to account for 78.3% of the variance in self-concept by stepwise regression analysis. Conclusion: Parents and clinicians should pay attention to improving the self-concept of children and adolescents with epilepsy, especially if they have problems with depression, anxiety, or attention.

Objectives: 1) To determine mercury levels in urine samples from garbage workers in Southern Thailand, and 2) to describe the association between work characteristics, work positions, behavioral factors, and acute symptoms; and levels of mercury in urine samples. Methods: A case-control study was conducted by interviewing 60 workers in 5 hazardous-waste-management factories, and 60 matched non-exposed persons living in the same area of Southern Thailand. Urine samples were collected to determine mercury levels by cold-vapor atomic absorption spectrometer mercury analyzer. Results: The hazardous-waste workers' urinary mercury levels (10.07 ${\mu}g/g$ creatinine) were significantly higher than the control group (1.33 ${\mu}g/g$ creatinine) (p < 0.001). Work position, duration of work, personal protective equipment (PPE), and personal hygiene, were significantly associated with urinary mercury level (p < 0.001). The workers developed acute symptoms - of head-aches, nausea, chest tightness, fatigue, and loss of consciousness at least once a week - and those who developed symptoms had significantly higher urinary mercury levels than those who did not, at p < 0.05. A multiple regression model was constructed. Significant predictors of urinary mercury levels included hours worked per day, days worked per week, duration of work (years), work position, use of PPE (mask, trousers, and gloves), and personal hygiene behavior (ate snacks or drank water at work, washed hands before lunch, and washed hands after work). Conclusion: Changing garbage workers' hygiene habits can reduce urinary mercury levels. Personal hygiene is important, and should be stressed in education programs. Employers should institute engineering controls to reduce urinary mercury levels among garbage workers.

Purpose: This study was done to provide support material to traditional nursing interventions through investigation of the effect of Auricular acupressure therapy for female staff in the hospital who have dysmenorrhea but cannot be absent from work even with severe symptoms affecting their work and therefore cannot get proper pain management. Method: The participants in this study were 62 women were working in the G-university hospital in Jin-ju, assigned to experimental (30) and 32 control groups (32). The study method was a quasi-experimental, nonequivalent control group non-synchronized design. The experimental group received acupressure treatment (a pin was attached to tape) on the special stimulation points in the inside of the ear, 5 times for 5 seconds, morning, afternoon, and night. Tape without the pressure pin was applied to the same points for women in the control group to evaluate placebo effect. Data were collected from May to November 2007 and were analyzed using SPSS PC+ 12 version. Descriptive statistics, t-test, $x^2-test$, Fisher's exact test, paired t-test, were used to analyze the data. Results: The experimental group showed a significant decrease in dysmenorrhea compared to the control group (t=-2.743, p<.01). In the sub-part, the experimental group showed menstruation related pain (t=-3.726, p<.01), menstruation related to behavioral change (t=-2.421, p<.05) and symptoms however, there was no significant difference related to attention deficit, water retention, and negative image. Conclusion: Application of auricular acupressure therapy was approved for this study and although auricular acupressure therapy was not effective for all of the symptoms, it was effective for dysmenorrhea.

Objectives: This study aimed to evaluate the effects of occlusion patterns using the T-scan $III^{(R)}$ system and oral parafunctional behaviors on temporomandibular joint disorder (TMD) in female college students. Methods: A questionnaire survey assessed TMD symptoms and oral behavioral checklist (OBC) scores in 120 female college students in their early twenties. Occlusion was evaluated using the T-scan $III^{(R)}$ system. Logistic regression analysis was performed to investigate the relationship between occlusion and OBC scores based on patients' symptoms of TMD and to determine whether OBC scores were a predictor of TMD. Results: A total of 101 participants with an average age of 22 (${\pm}2.17$) years were included in the analysis. The reported symptoms of TMD were categorized as moderate (28.8%), slight (27.7%), severe (25.7%), and asymptomatic (17.8%). Occlusion was analyzed using the T-scan $III^{(R)}$ system, and the mean occlusion time was 0.42(${\pm}0.5$) seconds. The results of logistic regression analysis showed that the group that would 'clench or grind teeth' during sleep showed an odds ratio for TMD that was 8.9 times higher than that in the group without this behavior. The group that would 'hold, tighten, or tense muscles without clenching' while awake showed an odds ratio for TMD that was 21.3 times higher than that in the group without this behavior. Conclusions: We confirmed that oral parafunctional behavior affects TMD. Therefore, we would like to continue studying the diagnosis and treatment of TMD by evaluating occlusion patterns and related OBC scores.

Background: Correctional officers (COs) experience elevated rates of mental and physical ill-health as compared with other general industry and public safety occupations. The purpose of this study was to investigate demographic, mental health, job tenure, and work-family characteristics and their prospective association to burnout within and between jail officers during one year of new employment. Methods: In 2016, newly hired jail officers (N = 144) completed self-reported surveys across four time points in a one-year prospective study at a Midwestern United States urban jail. Linear mixed-effects and growth modeling examined how work-family conflict (W-FC) and depressive symptoms relate to perceptions of burnout over time. Results: Jail officer burnout increased and was related to rises in W-FC and depression symptoms. Within-person variance for W-FC (B_pooled = .52, p < .001) and depression symptoms (B_pooled = .06, p < .01) were significant predictors of burnout. Less time on the job remained a significant predictor of burnout across all analyses (B_pooled = .03, p < .001). Conclusions: Results from this study indicate that burnout increased during the first year of new employment; and increased W-FC, higher depression, and brief tenure were associated with burnout among jail COs. Future study of correctional workplace health is needed to identify tailored, multilevel interventions that address burnout and W-FC prevention and early intervention among COs.

Purpose: The aim of this study was to develop a mobile app-based musculoskeletal exercise program (AMSEP) for operating room (OR) nurses and evaluate its effects on self-efficacy, the flexibility of the shoulders, lower back, and legs, and musculoskeletal symptoms and fatigue. Methods: The AMSEP was developed based on the information-motivation-behavioral skill model. In total, 48 OR nurses were recruited at a university hospital in Korea and divided into an experimental group (n=24) and a control group (n=24), matched for career experience in the OR. The experimental group participated in the AMSEP, while the control group received a booklet regarding musculoskeletal exercise. Results: The experimental group showed significant increases in self-efficacy (t = -2.77, p = .008) and flexibility of the right shoulder (t = -4.08, p < .001), left shoulder (t = -3.28, p = .002), lower back (t = -3.75, p < .001), and legs (t = -3.96, p < .001) compared to the control group. Musculoskeletal symptoms (t = 2.75, p = .008), and fatigue (Z = -1.98, p = .048) significantly decreased in the experimental group compared to the control group. Conclusion: Our findings indicate that the AMSEP for OR nurses provided information on the prevention of musculoskeletal disorders and methods of exercise, as well as an opportunity for continued exercise performance through self-management. The AMSEP was easily accessible and effective in increasing self-efficacy and flexibility and reducing musculoskeletal symptoms and fatigue.

The poultry industry, which produces excellent sources of protein, suffers enormous economic damage from diseases. To solve this problem, research is being conducted on the early detection of infection according to the behavioral characteristics of poultry. The purpose of this study was to evaluate the potential of a non-movement behavior observation method to detect sick chickens. Forty 1-day-old Ross 308 males were used in the experiments, and an isolator equipped with an Internet Protocol (IP) camera was fabricated for observation. The chickens were inoculated with Salmonella enterica serovar Gallinarum A18-GCVP-014, the causative agent of fowl typhoid (FT), at 14 days of age, which is a vulnerable period for FT infection. The chickens were continuously observed with an IP camera for 2 weeks after inoculation, chickens that did not move for more than 30 minutes were detected and marked according to the algorithm. FT infection was confirmed based on clinical symptoms, analysis of cardiac, spleen and liver lesion scores, pathogen re-isolation, and serological analysis. As a result, clinical symptoms were first observed four days after inoculation, and dead chickens were observed on day six. Eleven days after inoculation, the number of clinical symptoms gradually decreased, indicating a state of recovery. For lesion scores, dead chickens scored 3.57 and live chickens scored 2.38. Pathogens were re-isolated in 37 out of 40 chickens, and hemagglutination test was positive in seven out of 26 chickens. The IP camera applied with the algorithm detected about 83% of the chickens that died in advance through non-movement behavior observation. Therefore, observation of non-movement behavior is one of the ways to detect infected chickens in advance, and it appears to have potential for the development of remote broiler management system.
