This study aimed to examine the development and characteristics of the workers with upper limb musculoskeletal symptoms and disorders and to analyze the upper limb musculoskeletal symptoms and disorders for its relationship with the individual socio-demographic characteristics. This study investigated the effect on the limitations of physical activities using standardized surveillance tool and clinical diagnosis. Musculoskeletal symptoms and the limitations of physical activities were examined. The clinical diagnosis of musculoskeletal disorders were carried out by physical examination, radiological examination and electromyography-electroneuronography for 22 workers in kitchen hood assembly process and 50 workers in toggle process of leather product manufacturing. The proportion of workers with musculoskeletal disorders was higher and the DASH score was also statistically higher in female and aged workers with longer working hours, longer household working hours, less leisure/hobby activity and higher physical load. Physical activities component score increased in the following order: workers in normal health, workers with musculoskeletal symptoms, and workers with musculoskeletal disorders as clinically diagnosed. Score for each DASH component increased in the following order: sports/performing arts ability, social activities, specific physical functional activities, work or other regular daily activities, work ability, psychological activities, insomnia and upper limb symptoms. The overall and each component DASH scores were higher in workers with symptoms of status praesens and of more severity, and receiving medical intervention. Musculoskeletal symptoms and disorders are associated with individual socio-demographic characteristics, and DASH score for physical activities of upper limb was higher in workers with musculoskeletal disorders. Musculoskeletal symptoms and disorders have a remarkable epidemiological significance for physical activities, social activities, work or other regular daily activities, upper limb symptoms and insomnia, where work ability, sports/performing arts ability and preventive measure is needed.

Objects : This study is to be applied effectively to the acupuncture treatment for VDT syndrome. Methods : I referred to occidental and oriental medical records. Results and Conclusion : VDT syndrom is the concept focalizing work environment and labor load, and named all that symptoms according to excessive VDT works. The disorders of VDT syndrome is divided into 2 groups with muscaloskeletal disorders and non-musculoskeletal disorders, and non-musculoskeletal disorders is secondly divided into 3 groups with visual disorders, stress disorders and others. The risk factor of VDT syndrome is divided 4 groups with repetitive acts, consistent works, uncomfortable work postures, unprofitable light environments, jobs needs for excessive power and mental or physical fatigues. In oriental medicine area, I apply VDT syndrome to Kyunbitong(jianbeitong, 肩臂痛) to base on similarities of the risk factors and disorders between VDT syndrome and Kyunbitong(jianbeitong, 肩臂痛), that is painful illness on shoulders, arms, hands and fingers. And, Kyunbitong(jianbeitong, 肩臂痛) is divided 3 groups into Susamuhm(shousanyin, 手三陰), Susamyang(shousanyang, 手三陽) and Joktaeyang(zutaiyang, 足太陽) on the ground of meridian. Disorders related to Kyunbitong(jianbeitong, 肩臂痛) is grounded on kyungmaek(Jingmai, 經脈) disorder called sidongbyung(shidongbing, 是動病) and sosaengbyung(suoshengbing, 所生病) and Kyungkeun(Jingjin,經筋) disorder related to Kyunbitong(jianbeitong, 肩臂痛). As a result of this study, there is many similarities between VDT syndrome and Kyunbitong (jianbeitong, 肩臂痛). On acupuncture treatment, VDT syndrome can be applied to Kyunbitong(jianbeitong, 肩臂痛)'s on the basis of meridians, because of similarities of risk factors and disorders between VDT syndrome and Kyunbitong(jienbeitong, 肩臂痛).

Purpose: There is increasing prevalence of psychiatric disorders among inflammatory bowel Disease (IBD) population. Further, presence of psychiatric disorders has been shown as an independent predictor of quality of life among patients with IBD. We intended to explore the prevalence of various psychiatric disorders among pediatric and young adult population with IBD as a population-based analysis. Methods: We did a retrospective case control analysis using a deidentified cloud-based database including health care data across 26 health care networks comprising of more than 360 hospitals across USA. Data collected across different hospitals were classified and stored according to Systematized Nomenclature of Medicine-Clinical Terms. We preidentified 10 psychiatric disorders and the queried the database for the presence of at least one of the ten psychiatric disorders among IBD patients between 5 and 24 years of age and compared with controls. Results: Total of 11,316,450 patients in the age group between 5 and 24 years and the number of patients with a diagnosis of IBD, Crohn's disease or ulcerative colitis were 58,020. The prevalence of psychiatric disorders was 21.6% among IBD mainly comprising of depression and anxiety disorder. Multiple logistic regression analysis showed, IBD is 5 times more likely associated with psychiatric disorders than controls, p<0.001). We showed a steady increasing trend in the incidence of psychiatric disorders among IBD patients (2% in 2006 to 15% in 2017). Conclusion: Largest population-based analysis demonstrated an increased prevalence of psychiatric disorders among IBD patients. Our study emphasizes the need for psychological and mental health services to be incorporated as a part of the routine IBD clinic.

Purpose : This study was conducted to investigate whether phonetic complexity affected the type and frequency of articulation errors and the acoustic duration of consonants and words produced by children with functional articulation and phonological disorders. Methods : The participants in this study were 20 children with functional articulation and phonological disorders and 20 children without such disorders who were between 3 years 7 months old and 4 years 11 months old. The participants were asked to name what they saw in pictures and their responses were recorded. The types and frequencies of articulation errors and the acoustic duration of words were analyzed and words were categorized as being of either 'high' or 'low' phonetic complexity. The acoustic duration of initial and final consonants and vowels following initial consonants were compared between the groups according to articulatory complexity. Results : Children with functional articulation and phonological disorders produced articulation errors more frequently when saying high complexity words and had longer word duration when saying low-complexity words than children without such disorders. There was no major difference in initial and final consonant duration between the groups. but the main effect of articulatory complexity on the duration of both consonants was significant. Conclusion : These results suggest that the articulatory-phonic structure of words influences the speech motor control ability of children with functional articulation and phonological disorders. When articulating consonants, children with functional articulation and phonological disorders had speech motor control ability similar to that of children without such disorders.

Purpose: The incidence and prevalence of inflammatory bowel disease (IBD) are increasing along with an increasing number of patients with comorbid conditions like psychiatric and behavioral disorders, which are independent predictors of quality of life. Methods: Non-overlapping years (2003-2016) of National Inpatient Sample and Kids Inpatient Database were analyzed to include all IBD-related hospitalizations of patients less than 21 years of age. Patients were analyzed for a concomitant diagnosis of psychiatric/ behavioral disorders and were compared with IBD patients without psychiatric/behavioral disorder diagnoses for outcome variables: IBD severity, length of stay and inflation-adjusted hospitalization charges. Results: Total of 161,294 IBD-related hospitalizations were analyzed and the overall prevalence rate of any psychiatric and behavioral disorders was 15.7%. Prevalence rate increased from 11.3% (2003) to 20.6% (2016), p<0.001. Depression, substance use, and anxiety were the predominant psychiatric disorders. Regression analysis showed patients with severe IBD (odds ratio [OR], 1.57; confidence interval [CI], 1.47-1.67; p<0.001) and intermediate IBD (OR, 1.14; CI, 1.10-1.28, p<0.001) had increased risk of associated psychiatric and behavioral disorders than patients with a low severity IBD. Multivariate analysis showed that psychiatric and behavioral disorders had 1.17 (CI, 1.07-1.28; p<0.001) mean additional days of hospitalization and incurred additional $8473 (CI, 7,520-9,425; p<0.001) of mean hospitalization charges, independent of IBD severity. Conclusion: Prevalence of psychiatric and behavioral disorders in hospitalized pediatric IBD patients has been significantly increasing over the last two decades, and these disorders were independently associated with prolonged hospital stay, and higher total hospitalization charges.
