Self-injurious behavior (SIB) has been defined as the deliberate destruction or alteration of body tissue without conscious suicidal intent. It occurs in conjunction with a variety of psychiatric disorders as well as various developmental disabilities and some syndromes. The behavior is destructive and causes concern and distress to all involved in the care and treatment of the affected individual. A 13-year-old girl with autism, mental retardation and delayed development was reffered from her pediatrician because of severe and painful lower lip biting. An intraoral examination revealed a diffuse swelling of lower lip. It was covered with necrotic slough and the ulcer and scarring of the lower lip was observed. We chose to use an oral removable prosthesis for Conservative treatment. It was decided to use a soft silicone mouthguard in the maxillary arch. Initially, she could not tolerate the appliance inside her mouth but soon adapted with the appliance. After one month, she lost the mouth guard and started lip biting. So we made mouth guard again. There are no standard methods for preventing self-injurious behavior in a patient who is developmentally disabled. Appropriate preventive methods must be developed for each individual patient based on close observation and clinical findings. Behavior modification techniques, pharmacological treatment, extraction of teeth, orthognathic surgery and intra/extra oral appliances can be performed for adjust self-injurious behavior. A suitable oral guard could be tried initially before employing more invasive approaches.

Recently, improving public transport service at disabled people has emerged as a social issue in rural areas. By improving expensive and inefficient existing operating system, the rural bus have to change a personalized service. Under these circumstances, government and local governments are promoting the introduction of DRT(Demand response transport). DRT system is intended to promote the user's convenience. But, until now, in-depth research on the operating costs for the introduction of DRT is not well known. This study aims to look at changes in number of vehicle and operating costs before and after introduction of DRT. The results are as follows. Even though introducing DRT, total number of vehicles increases because it does not reduce the existing number of vehicles. And this study estimated to about 5 to 12 percent of the increase in the operating cost comparing before introduction of DRT. Therefore, The introduction of DRT in rural areas is a need to set the exact purpose as promote transportation convenience or cost efficiency.

This paper presents a technology for manipulating external devices by Brain Computer Interface (BCI) system. Recently, BCI based rehabilitation and assistance system for disabled people, such as patient of Spinal Cord Injury (SCI), general paralysis, and so on, is attracting tremendous interest. Especially, electroencephalogram (EEG) signal is used to organize the BCI system by analyzing the signals, such as evoked potential. The general findings of neurophysiology support an availability of the EEG-based BCI system. We concentrate on the event-related synchronization of motor imagery EEG signal, which have an affinity with an intention for moving control of external device. To analyze the brain activity, short-time Fourier transform and particle swarm optimization are used to optimal feature selection from the preprocessed EEG signals. In our experiment, we can verify that the power spectral density correspond to range mu-rhythm(${\mu}8$~12Hz) have maximum amplitude among the raw signals and most of particles are concentrated in the corresponding region. Result shows accuracy of subject left hand 40% and right hand 38%.

Excessive oral and maxillofacial bleeding causes upper airway obstruction, bronchotracheal and gastric aspiration and hypovolemic shock. Therefore, the rapid and correct bleeding control is very important for saving lives in the emergency room. Despite the conventional bleeding control methods of wiring (jaw fracture, wound suture and direct pressure), continuous bleeding can occur due to the presence of various bleeding disorders. There are five main causes for excessive bleeding disorders in the clinical phase; (1) vascular wall alteration (infection, scurvy etc.), (2) disorders of platelet function (3) thrombocytopenic purpura (4) inherited disorders of coagulation, and (5) acquired disorders of coagulation (liver disease, anticoagulant drug etc.). In particular, infections can alter the structure and function of the vascular wall to a point at which the patient may have a clinical bleeding problem due to vessel engorgement and erosion. Wound infection is a frequent cause of postoperative active bleeding. To prevent postoperative bleeding, early infection control using a wound suture with proper drainage establishment is very important, particularly in the active bleeding sites in a contaminated emergency room. This is a case report of a rational bleeding control method by rapid wiring, wound suture with drainage of a rubber strip & iodoform gauze and wet gauze packing, in a 26-year-old male cerebral palsy patient with active oral and maxillofacial bleeding injuries caused by a traffic accident.

This study was conducted to find out the effects of visiting companion dog program on people with chronic mental disability. Visiting companion dog program was carried out for one hour every week for about three months between January and March of 1997 for chronic schizophrenic patients with severe negative symptoms and evaluated by the treatment team as those who are incapable of participating in any other program aside from medication. In order to measure the effects of the program PANSS: Positive and Negative Syndrome Scale was conducted by two trained evaluators. The results showed that there was a statistically significant decrease in scores of negative symtoms and general psypathological symtoms. Moreover, scaling scores reported by the nurses and occupational therapist also reveal that the patients show positive changes such as improvement in conversational interaction and facial expressions. Such results evidence that companion animals can have positive emotional and mental influence on people with chronic mental disability. Furthermore the fact that the visiting companion dog program became a program that the chronically mentally disabled who could not participate in any other program can easily participate and enjoy is a meaningful finding in and of itself.

This study has investigated the status and overview of design characteristics of customized shoes, which receives much recognition at domestic and overseas markets. Based on the market research on current consumer lifestyle and needs of the custom-shoes(which is an abbreviation of customized shoes), this study has provided its development directions, views and demands. The design types of custom-shoes have been broadly divide into two: firstly 'style centered custom-shoes'; secondly 'function centered custom-shoes'. Style centered custom-shoes are specifically divided into 3 types; first, formal custom-shoes; second, sports and casual custom-shoes; and lastly, bespoke shoes. Function centered custom-shoes design refers to enhancing the function of personal soleprint which has to be designed by delicately detailed insole and outsole, rather than alignment of exterior parts of the shoes. These are used in professional sports shoes and also include orthopedics footwear and grafted footwear for people who have disabled on foot. Custom footwear market has been highly expanded and has entered value-added market according to increasing interest in foot health and shopping trends on shoes buying like taking shoes as personal expression in accordance with a variety of places and situations. In the near future, custom-shoes can be produced in a couple of days due to the technological advance of 3D scanners and 3D printers. This phenomenon will wants more demands of specific shoes experts such as custom-design consultants or shoes fitting experts, who can overcome limitations of online custom-shoes stores.

Although the stainless steel crowns have been recognized as the most effective and durable form of restoration for primary molars, they have been regarded by many dentists as having definite demerits such as invasive nature of procedural complexity and behavioral aspects of children. As an alternative to conventional technique of stainless steel crown restoration, the Hall technique was first introduced in 1988, which is characterized by just pushing the pre-contoured, cement filled crown form onto the abutment molar with no local anesthesia, no caries removal, no tooth preparation. According to several reports, this can slow, arrest, or even reverse the progress of caries. In addition, its atraumatic feature gives less discomfort and stress to children than conventional one, which is thought excellent especially in younger children. Also, It has been reported to be effective and acceptable to dentist, child patients and their parents. In this case study, three children with age of 4 years 5 months, 4 years 10 months, 6 years 4 months were treated with stainless steel crowns using Hall technique on first primary molar respectively. The teeth were free from pulpal, periapical pathology. After follow up of about 3 to 6 months period, the results showed clinically successful outcomes without any marked complication in pulp, tooth or soft tissue till now. But, it should be kept in mind that this technique is not proper to every child, every carious molar, or every dentist. Thorough distinction of indicated cases and continuous follow-up check is highly required. Conclusively, Hall technique might be an effective and realistic minimally invasive alternative for the carious primary molars especially in younger or disabled children, despite potential doubts on its efficacy and some definite limitations.

To date, the study of students with multicultural disabilities has been limited to language problems. The purpose of this study was to investigate the effects of communication between parents and professionals on the IEP and teaching strategies of students in multicultural special education in the United States. From 2015 to 2016, structural equation modeling was conducted using AMOS 21 based on data from 406 elementary, middle, and high school teachers who has experiencing of multicultural disabilities. The correlation coefficients between IEP and the variables affecting instructional strategies were significantly high between -044 and .489 as a whole. Especially, teaching strategy and communication with parents were relatively more effective than professional communication high correlation. In addition, with regard to the impact on IEP and teaching strategies, parental communication has been found to be closely related to IEP and teaching strategies. However, communication with professionals has a direct effect on teaching strategies. There was no significant correlation between parent and professional communication. The purpose of this study is to understand the importance of communication with parents of multicultural disabled students and their interest and opinions on children positively to IEP and teaching strategies so that teachers can communicate continuously.

The exoskeleton robot to assist walking of hemiplegia patients or disabled persons has been studied in this paper. The exoskeleton robot with degrees of freedom of 2 axis has been developed and tested for joint motion. The obtained EMG signal from normal person was analyzed and the control signal was extracted from it for convenient and automotive performance of assistance robot to help hemiplegia patient walks as normal person does. the purpose of using FES(Functional Electrical Stimulation) for hemiplegia patient's walk is to restore damaged body function by this, but this could give fatal electrical shock to patients by wrong use or cause quick fatigue in muscle by continuous stimulation. The convenient movement of hemiplegia patients with minimum muscle fatigue was looked possibly by operation of assistance robot exoskeleton using control signal. and the walking assistance exoskeleton robot seemed works more efficiently than using FES stimulator. The experiment in this study was performed based on usual motion in our life like walking, standing-up, sitting-down, and particularly feedback control system using Piezo sensor along with button switch was applied for smooth swing motion in walking. The experiment also shows that hemiplegia patients can move conveniently by using electromyogram signal of healthy leg for the operation signal of assistance robot system attached at damaged symmetrical leg.
