As the world's elderly population increases, the proportion of visually impaired is also increasing, and there are still many restrictions on the use of outside activities, such as safety problems and lack of guidance information. To solve this problem, research on smart devices such as smart glasses with optical character recognition (OCR) function is being actively conducted. In this paper, we propose a system that recognizes obstacles ahead and informs information by voice, and also guides the way to the destination. Using the deep learning object recognition model Yolo, it let them to recognize the risk factors as obstacles such as stairs and Larva cones. and it also deliver the information with a voice. so you can expect that the visually impaired can do a lot of different activity even more now that system takes the visually impaired to the destination by using the directions API, voice recognition, TTS library.

최근 들어 기후변화와 함께, 화재 발생이 증가함에 따라 인명피해와 경제적 피해가 늘고 있다. 화재 발생시 인명 피해를 줄여주는 소방시설 중 경보설비와 유도등설비는 위험 상황시 경보와 함께 동선을 유도하는 유도등을 보고 재실자들이 안전한 공간으로 신속하게 대피할 수 있도록 하는 소방설비 이다. 이중에서 유도등설비는 화재발생 상황에서 매우 중요한 역할을 맡고 있다. 특히 복잡한 동선을 가지고 있는 복합건물 및 지하철, 고층건축물에 신속한 대피 유도에 필요한 설비이다. 그러나, 화재 초기에 신속한 대피를 해야 하는데 5분도 되지 않아 화재로 인해 발생한 가스는 검은 연기로 유도등의 역할과 효과를 저해하는 현상을 가져온다. 즉 유도등의 녹색빛이 보이지 않는다. 이는 저시력자 또는 시력에 장애를 가지고 있는 자들은 더욱더 유도등을 확인하고 대피 하기란 쉽지 않게 된다. 이런 단점이 있는 기존의 유도등에 IoT(Internet of Things)와 함께 증강현실 이미지를 스마트기기에 활성화 한다면, 진한 검은연기로 인한 빛의 가림으로 인한 유도장애에 대해서 개선 할 수 있을 거라 생각되어, 변류기의 전류 감지를 시작으로 그 신호를 스마트기기에 녹색의 유도 이미지를 활성화하여 골든타임에 대피가 신속하도록 설비를 구현하여 그 가능성을 확인하였다.

The Korean Mental Health Act was amended 2016 overall. This paper examines and evaluates the old Korean Mental Health Act since 1995 and the new Korean Mental Health Promotion Act 2016 from the Perspective of Human Rights and Inclusion of Persons with Psychosocial Disabilities. The persons with mental disabilities was separated and ruled out from society by the enactment of the Mental Health Act in 1995 and five times amendment. That has been justified and institutionally supported by medical viewpoint. The medical approach which reconsider the persons with mental disabilities as patients conceal that the aims of the involuntary admission in Mental Hospital are protection of society and the relief of the family member's duty of support for person with mental disabilities. This is institutionally supported in the 1995 Korean Mental Health Act by involuntary admission through the consent of family members as protectors. According to the old Act, the family members as protectors are authorized to consent to involuntary admission of persons with mental disabilities. Also, the psychiatrist that diagnoses the person with mental disabilities and evaluates the need for treatment by admission is not impartial in this decision. Family members as protectors may want to lighten their burden of support for the person with mental disabilities in their home by admitting them into a mental hospital, and the psychiatrist in the mental hospital can be improperly influenced by demand of hospital management. Additionally, Article 24 of the Korean Mental Health Act for the Involuntary Admission by the Consent of Family Members as Protector might violate personal liberty, as guaranteed in the Korean Constitution. The Mental Health Promotion Law was amended to reduce the scope of the persons with mental illness which are subject to forced hospitalization and to demand that a second diagnosis is made by another psychiatrist and screening by the committee concerning the legitimacy of admission in the process of the involuntary admission by the consent of family members as a method of protection. The amended Mental Health Promotion Law will contribute to reducing the number of the involuntary admissions and the inclusion of persons with mental disabilities. But if persons with mental disabilities are not providing some kind of service to the community, the amended Mental Health Promotion Law does not work for Inclusion of them.

It was 1988 when people pay attention to an importance of the facilities for the handicapped, with Seoul Paralympics. In early 1990s, regular efforts were made to improve a physical environment for the handicapped, which results in reforming the Welfare Law for the Handicapped all over the surface. However, keeping pace with the expansion of the western universal design concept, it is required to evaluate a new concept in which way the facilities for the handicapped must be installed. That is, any physical environment, which regards the handicapped as an independent subject, tend to isolate them from normal people rather than satisfy their needs. making the handicapped feel more discriminated. All the facilities for the handicapped has to reflect a general idea that the facilities are opened for all the people including the handicapped. Being recently reformed and enacted in order to reflect this essential point, 'the raw of contributing to the convenience of the handicapped, aged men, pregnant women and nursing mother(1998)' even covers the aged men, pregnant women and nursing mother, not to mention of the handicapped. In addition, the law states clearly that all the handicapped can share all the facilities with the normal people, inducing the handicapped to more actively participate in society. Consequently, the handicapped are acquiring their rights by directly demanding for correction of varied discrimination. Though even more facilities have been provided, most of them are deficient in the quality, setting limits to the handicapped person's living field as well as social activities. Especially, most public buildings in our country rarely provide the adequate facilities for the handicapped, aged men, pregnant women and nursing mother. Therefore, this study is focused on developing the list of actual condition research that can effectively detect the inadequacy of facilities in public buildings. Then it will find the aspects to be improved in a systematic and scientific way to propose a practical method to improve the facilities in public buildings.

By developing rider robot using omni wheel drive, a usability test for 6 people was conducted after finding out inconvenient factors and ways of improvement. The results of this research are as follows. First, we researched inconvenient factors captured by object of experiment using a rider robot who is living in the dormitory. It showed that the disabled showing 1.6 of satisfaction degree felt more inconvenient for normal people showing 4 of satisfaction degree. It was found that the height of seats is 10 centimeters higher, which caused inconvenience for moving. Second, each of the disabled and normal people showed 2.33 and 2.62 of satisfaction degree below the average for seats, back of a seat, armrest, footrest, security belts. However, for the revised design both of them showed 3.5 of satisfaction degree over the average. Third, most people felt this robot is quite expensive and said they would purchase it if subsidized by the government. Therefore, based on inconvenient factors and ways of improvement found in this research, further study needs to be conducted so as to improve the quality of life of the disabled.

Hydrocephalus is characterized by accumulation of cerebrospinal fluid in the ventricles of the brain causing progressive ventricular dilatation. Accumulation of cerebrospinal fluid typically causes increased pressure inside the skull, this may result in headaches, vomiting, nausea, seizures, sleepiness and mental impairment. Patients with hydrocephalus may have dental manifestations such as changes in the occlusion and greater accumulation of plaque. The prevalence of dental caries is high due to the difficulty of oral care. The purpose of this case report is to describe the dental care for an uncooperative child with hydrocephalus under general anesthesia.

This study suggests a new platform in which VI can communicate with their guardians who serve as a system administrator optimizing personal characteristics. In terms of interaction between platform components, this study can contribute to enhancing stability of walking by giving substantial information to VI through server processing and setups of guardians with real-time interaction to VI through server processing and setups of guardians with real-time interaction. Therefore, developing smart phone applications can facilitate both portability and cost effectiveness, by the users' downloading the application and registration. In terms of guardians' cost, this system is cost-effective because they can access to the administration system through personal computers or smart phones, not through specialized system devices. This system is web-based, which automatically communicates with the surroundings of, such as provides the guardians with the necessary information or approaches to the danger through IoT devices, which results in enhancing safety. Moreover, it is possible for guardians to utilize the personalized platform since the system not only senses personal characteristics but also sends a number of information to VI. a new platform makes it possible for guardians to provide electronic support and interaction with the application with the application users, which contributes to systematic and safe walk for VI.

Existing traffic safety studies have focused on identifying the relationship among roadway crashes, highway design and incremental weather condition such as rainy/ice weather. However, it is hard to find researches that studied the effect of sun glare on traffic safety although there are abundant evidences demonstrating that fatal traffic crashes are attributed to the sun glare. Affecting drivers'vision particularly during the morning or the evening time when the sun positions close to the horizon, sun glare directly deteriorate drivers'judgmental capability. In this paper, we numerically analyze the effect of sun glare on the drivers'vision in time and space domains. Applied to the roadways around St Louis area in the United States, the GIS based simulation analysis identifies the time of day in a year and the segments of highways that are potentially influenced by the sun glare. This study evidentially confirms the fact that roadway bounded for West and East directions have longer time influenced by sun glare particularly during Spring and Fall season than other roadways. The computational result provides risky time periods of day at intersections or pedestrian crossings where the sun glare potentially endangers traffic safety, which be utilized to reduce the crashes due to the sun glare.

Deep sedation is considered for the dental treatment of pediatric or disabled patients who have severe anxiety or involuntary movement. Deep sedation using sevoflurane inhalation in emergency dental practice, therefore, is also preferred for fast induction and recovery. This survey consists of 121 people with pediatric or disabled patients who underwent dental treatment under deep sedation using sevoflurane inhalation from January 2013 to October 2013. Patients who were scheduled for deep sedation were classified into a non-emergency sevoflurane sedation group, whereas patients who underwent emergency sedation due to trauma and patients with disabled characteristics itself were classified into an emergency sevoflurane sedation group. Of 121 patients studied, 95 patients received dental care under non-emergency sedation, 26 patients received dental care under emergency sevoflurane sedation. The two groups were analyzed according to: gender; age; primary reason for sedation; duration of sedation; treatment time; induction methods; treatment information; and departments. Non-emergency sevoflurane sedation in pediatric or disabled patients was safe and effective for controlling the behavior. Emergency sevoflurane sedation was a useful method for younger pediatric patients with traumatic injury who need simple, short time emergency treatment. Deep sedation using sevoflurane inhalation not only will reduce the use of general anesthesia gradually but also will be a useful method to emergency treatment for pediatric or disabled patients.

The purpose of this study was to test the effects of the pedestrian green signal adjustment on clearance of the turning vehicles impeding the through traffic flow at the signalized intersections, and thereby, suggest some operational criteria for adjustment of the pedestrian green signal. In order to test such effects, the pedestrian green time was adjusted so that it could started a few seconds later than the vehicle green time during peak hours, and thereby, the turning vehicle volume not cleared at the intersection was measured by extending the time gap by 2 seconds. (In general, the pedestrian green signal turns on at the same time as the vehicle green signal.) The results of this test can be summed up as follows; first, the longer the time gap was, the turning vehicle volume not cleared from the intersection decreased more. Second, in case there existed a storage space between intersection and crosswalk the effect of the turning vehicles on the through traffic flows was minimal. Third, at the pelican, the effect of the turning vehicles on the through traffic flow was minimal due to the structure of the intersection and the phase sequence. In conclusion, it was found that the adjustment of pedestrian green signal had the effect of enhancing the intersection operation. When adjusting the pedestrian green signal, it was deemed necessary to thoroughly survey the geometric structure of the intersection and collect the data on the turning traffic volume and thereby, apply the results of analysis flexibly to each intersection.
