Objectives & Methods : The objective of this study was to evaluate the single oral dose toxicity of Chongmyung-tang (CMT) in ICR mice. Korean traditional herbal prescription CMT has traditionally been used as a neuroprotective for treatment of learning disability and memory improvement. CMT, lyophilized aqueous extracts (yield=9.7%) were administered to female and male mice with oral dose of 2,000, 1,000 and 500 mg/kg (body weight) according to the recommendation of Korea Food and Drug Administration (KFDA) Guidelines. Animals were monitored for mortality, changes in body weight, clinical signs and gross observation during 14 days after administration upon necropsy; organ weight and histopathology of 14 principle organs were examined. Results : We could not find any CMT extracts treatment related mortalities, clinical signs, changes in body and organ weight, or gross and histopathological observations against 14 principle organs up to 2,000 mg/kg in both female and male mice, except for some accidental sporadic findings which did not show any obvious dose-relations and most of which also demonstrated in both the female and male vehicle control mice in this experiments. Conclusions : Based on the results of this experiment, the 50% lethal dose ($LD_{50}$) and approximate lethal dose (ALD) of CMT extracts after single oral treatment in female and male mice can be considered to be over 2,000 mg/kg, and is likely to be safe in humans.
The purpose of this study was to compare the physical and psychological functioning by sex, weight and age in Judo athletes. The 124 participants; high school students, college students, and team players. They used physical tests to measure physical examinations by self-describing Knee injury and Osteoarthritis Outcome Score test, Foot and Ankle Outcome Score test, and Oswestry Disability Index, and psychological tests such as Profile of Mood Test, Athletes' Self-Management Questionnaire, and The Athletic Coping Skills Inventory-28, to examine the effects of physical and psychological functions of sports athletes. The physical tests of sex showed differences in knee and back, psychological tests of sex showed differences in mood state, self-management, and athletic coping skills. As a result of physical examination by weight, there was a difference in knee pain and sports items, psychological tests showed that there was a significant difference in mood state except for vitality. Physical examination by age showed differences in knee, ankle, and back. As a result of age-based psychological test, mood state test showed difference in all items except tension and vitality. There was a significant difference only in the items of physical management in self-management test. The results of this study are expected to be used as a basic data for sports injury training and medical technology development by sex, weight and age of Judo athletes.

Prader-Willi Syndrome (PWS) is a rare neurologic disorder with a prevalence 1/10,000-30,000. The cause of PWS is an abnormalities of chromosome 15q11.2-q13 which is an imprinting gene. Obesity and hyperphagia are characteristic features on a PWS adult. On the other hand, the birth weight, height and body mass index (BMI) of PWS infants are 15-20% lower than those of normal babies and there is a failure to thrive until 24-month-old. Most of PWS patients are treated under general anesthesia and conscious sedation. This case is a treatment of severe caries in a PWS 46 month-old child without general anesthesia and conscious sedation. He came to the Department of Pediatric Dentistry, Kyung Hee University Dental Hospital at Gangdong, Seoul, Korea with a trauma history. He had a medical history with heart surgery and needed to take antibiotics prophylaxis. The luxated left upper primary tooth were removed and caries treatment were done as an outpatient without general anesthesia, conscious sedation.
Purpose: The purpose of this study was to develop and apply a motivation-strengthening obesity management program for obese subjects with visual impairment and evaluate its effects. Methods: The program development and evaluation periods were from March to August 2018. The study design was an experimental study of non-equality, control repeat design. 25 subjects in the experimental group participated in the 12-week obesity management program and the 26 people in the control group did not. Results: The motivation-strengthening obesity management program included stretching exercises for 30 minutes in the morning five times a week. In addition, counseling, education, and group discussions were continued once a week for motivational strengthening. Special custom exercises for blind patients were also completed once a week simultaneously. Both of these activities were continued for 50 minutes a week for a total of 12 weeks. Measurements were recorded periodically to identify the sustained effects of the program. The obese subjects with visual impairment improved their knowledge of obesity, perceived disability, self-efficacy of exercise, and quality of life related to obesity through the motivational obesity management program. Waist circumference, systolic blood pressure, diastolic blood pressure, and fasting blood sugar were also improved in obese subjects. Conclusion: The study findings indicate that this program could be an active intervention for the control of weight gain in participants with visual impairment. Therefore, the motivation-strengthening program based on the ADDIE (Analysis, Design, Development, Implementation& Evaluation) model could be an effective strategy for better health outcomes of obese subjects with visual impairment.
We need to understand the outcomes into adulthood for survivors born either extremely low birthweight (ELBW; <1,000 g) or extremely preterm (EP; <28 weeks' gestational age), particularly their blood pressure and cardiovascular metabolic status,respiratory function, growth, psychological and mental health performance, and functional outcomes. Blood pressure is higher in late adolescence and early adulthood in ELBW/EP survivors compared with controls. In some studies, expreterm survivors have higher insulin and blood lipid concentrations than controls, which may also increase their risk for later cardiovascular disease. ELBW/EP survivors have more expiratory airflow obstruction than do controls. Those who had bronchopulmonary dysplasia (BPD) in the newborn period have even worse lung function than those who did not have BPD. As a group, they are unlikely to achieve their full lung growth potential, which means that more of them are likely to develop chronic obstructive airway disease in later life. Although they are smaller than term born controls, their weight gradually rises and ultimately reaches a mean z-score close to zero in late adolescence, and they ultimately attain a height z-score close to their mid-parental height z-score. On average, ex-preterm survivors have intelligence quotient (IQ) scores and performance on tests of academic achievement approximately 2/3 SD lower than do controls, and they also perform less well on tests of attention and executive function. They have similar high rates of anxiety and depression symptoms in late adolescence as do controls. They are, however, over-represented in population registries for rarer disorders such as schizophrenia and Autism Spectrum Disorder. In cohort studies, ex-preterm survivors mostly report good quality of life and participation in daily activities, and they report good levels of self-esteem. In population studies, they require higher levels of economic assistance, such as disability pensions, they do not achieve education levels as high as controls, fewer are married, and their rates of reproduction are lower, at least in early adulthood. Survivors born ELBW/EP will present more and more to health carers in adulthood, as they survive in larger numbers.
Traumatic brain injury (TBI) is a major cause of mortality and long-term disability, which can decrease quality of life. In spite of numerous studies suggesting that Epigallocatechin-3- gallate (EGCG) has been used as a therapeutic agent for a broad range of disorders, the effect of EGCG on TBI remains unknown. In this study, a weight drop model was established to evaluate the therapeutic potential of EGCG on TBI. Rats were administered with 100 mg/kg EGCG or PBS intraperitoneally. At different times following trauma, rats were sacrificed for analysis. It was found that EGCG (100 mg/kg, i.p.) treatment significantly reduced brain water content and vascular permeability at 12, 24, 48, 72 hour after TBI. Real-time PCR results revealed that EGCG inhibited TBI-induced IL-$1{\beta}$ and TNF-${\alpha}$ mRNA expression. Importantly, CD68 mRNA expression decreasing in the brain suggested that EGCG inhibited microglia activation. Western blotting and immunohistochemistry results showed that administering of EGCG significantly inhibited the levels of aquaporin-4 (AQP4) and glial fibrillary acidic protein (GFAP) expression. TBI-induced oxidative stress was remarkably impaired by EGCG treatment, which elevated the activities of SOD and GSH-PX. Conversely, EGCG significantly reduced the contents of MDA after TBI. In addition, EGCG decreased TBI-induced NADPH oxidase activation through inhibition of $p47^{phox}$ translocation from cytoplasm to plasma membrane. These data demonstrate that EGCG treatment may be an effective therapeutic strategy for TBI and the underlying mechanism involves inhibition of oxidative stress.
Tarsometatarsal fracture-dislocation is uncommon but severe lesion. Since this lesion is sometimes difficult to recognize by roentgenography, it is easily overlooked. Three patients were treated with open reduction and internal fixation with 3.5 mm cannulated screw and K-wire, two had treatment with open reduction and internal fixation with 3.5 mm cannulated screw only and two had treatment with dosed reduction and short leg cast only between January 1994 and May 1996. The duration of follow-up ranged from twelve to twenty-nine months after the diagnosis. Results were assessed by a subjective questiormaire, physical examination, and radiographic analysis. Multiple fixation techniques for maintaining the reduction of tarsometatarsl joint have been introduced. We recent]y used the 3.5 mm cannulated screw for internal fixation of the tarso-first and second metatarsal fracture-dislocation. We think cannulated screw fixation has several advantages; 1. The cannulated screw fixation is more rigid than the K-wire fixation. 2. There is an decreased risk of screw breakage with early weight bearing. 3. It is possible to compress the involved joints, if necessary. There were no disability in all patients. One patient who was treated with delayed open reduction and internal fixation with 3.5 mm cannulated screw and K-wire had a radiographic mild degenerative arthritis. And one patient who was treated with dosed reduction and short leg cast had a mild metatarsus adductus. But. these two patients were symptom free. There was no correlation between the severity of the diastasis and the patient s functional result.

Purpose: The aim of this study is to compare and assess the effects of lumbar stabilization exercise on the balance ability of young college studets with low back pain after having performed spinal stabilization exercise by using 3-dimensional air-balance system and gym ball. Methods: The subjects of this study were 34 low back patients in their early twenties. They were divided into two groups: 3-dimensional lumbar stabilization exercise group(N=17) and gym ball lumbar stabilization exercise group(N=17). The period of the intervention was for five weeks. VAS(Visual Analogue Scale) for pain test, ODI(Oswestry Disability Index) for ADL limitation test, Tetrax system for static balance test, and Air-balance system 3D for dynamic balance test were used as evaluation tools for this study. Results: Pain showed significant decrease in both groups after having performed the experiment, but ADL limitation of the groups did not show any remarkable difference between before and after the experiment. Dynamic balance ability in the 8-directional angle comparison test significantly increased in all directions except for the backward, left-backward, and right-backward directions. As for dynamic balance ability in the 8-directional postural test, 3D exercise group showed statistically significant reduction in every direction while gym ball exercise group did not(p<.05). However, when it comes to static balance ability in the weight distribution and stability test, there was not significantly change between pre and post test in both groups. Conclusion: This study shows 3-dimensional lumbar stabilization exercise is more effective in the lumbar stabilization of coordinated movement than gym ball exercise, which may imply that 3D air-balance system can be used for the therapeutic treatment of body imbalance for patients with low back pain.
This study aims to investigate development directions for smart contents to support enhancing adaptive behavior skills of children with autistic disorder in elementary school. AHP survey of experts including special education teachers and directors in educational institution for disability children was performed to analyze importance weight for smart contents development necessity and effectiveness in adaptive behavior skills. And the smart contents development suitability through pre-discussion for idea generation for various development method and AHP survey with smart application development experts was evaluated. The results show that the effective and suitable adaptive behavior skills for smart contents development were understanding of languaging, time management and keeping, movement skills, wearing clothes, and personal hygiene in order of importance. Based on this study, education authorities should make an effort not to develop fragmentary educational smart contents but to support development of smart contents and service systems with better effectiveness and usability to meet demand for special education teachers and parents considering characteristics of children with autism.

PURPOSE: The aim of this study was to determine the effect of device considering Mckenzie type for the subjects with forward head posture (FHP). METHODS: The subjects were 35 patients with FHP (mean age was $23.7{\pm}2.8$ years; mean height; $172.1{\pm}11.7$, mean weight; $65.8{\pm}13.9$, mean NDI(Neck Disability Index; $3.7{\pm}3.2$, mean FHP; $6.7{\pm}2.2$). We measured the posture with the Body style S-8.0(LU Commerce, South Korea) to evaluate the FHP. We collected the surface EMG(Myosystem 1400, Noraxon, USA) data to quantify changes in normalized activation levels of muscles in SternoCleidoMastoid muscle(SCM), Scalenus Anterior(SA), Trapezius upper fiber(TU) and Splenius Cervicis(SC), during the subjects were instructed to glide their head into a "chin-in" position for a retraction without and with device. RESULTS: The condition with device significantly decreased the %RVC of SA($90.84{\pm}40.54$), SCM($74.98{\pm}43.65$) and TU($67.60{\pm}47.83$) compared to the condition without device(SA;$100.39{\pm}56.32$, SCM;$119.03{\pm}109.26$, Trapezius;$80.55{\pm}39.27$). But the %RVC of capitis($65.87{\pm}47.83$) with device was increased($70.82{\pm}52.78$). There was significant difference in the %RVC between SCM and Trapezius muscle in two conditions. CONCLUSION: New device for FHP reduces the EMG activities of the TU, SCM and SA muscle. We have to develop the function of feedback to facilitate the motion in the future.
