Background: The submucous cleft palate (SMCP) is a type of cleft palate that may result in velopharyngeal insufficiency (VPI). Palate muscles completely separate oral and nasal cavities by closing off the velopharynx during functional processes such as speech or swallow. Also, hypernasality may arise from anatomical or neurological abnormalities in these functions. Treatments of this issue involve a combination of surgical intervention, speech aid, and speech therapy. This case report demonstrates successfully treated VPI resulted from SMCP without any surgical intervention but solely with speech aid appliance and speech therapy. Case presentation: A 13-year-old female patient with a speech disorder from velopharyngeal insufficiency that was caused by a submucous cleft palate visited to our OMFS clinic. In the intraoral examination, the patient had a short soft palate and bifid uvula. And the muscles in the palate did not contract properly during oral speech. She had no surgical history such as primary palatoplasty or pharyngoplasty except for tonsillectomy. And there were no other medical histories. Objective speech assessment using nasometer was performed. We diagnosed that the patient had a SMCP. The patient has shown a decrease in speech intelligibility, which resulted from hypernasality. We decided to treat the patient with speech aid (palatal lift) along with speech therapy. During the 7-month treatment, hypernasality measured by a nasometer decreased and speech intelligibility became normal. Conclusions: Surgery remains the first treatment option for patients with velopharyngeal insufficiencies from submucous cleft palates. However, there were few reports about objective speech evaluation pre- or post-operation. Moreover, there has been no report of non-surgical treatment in the recent studies. From this perspective, this report of objective improvement of speech intelligibility of VPI patient with SMCP by non-surgical treatment has a significant meaning. Speech aid can be considered as one of treatment options for management of SMCP.

전치부에 발생한 치간이개는 심미적으로 문제를 일으키는 흔한 원인이 된다. "Black triangle"을 생성시키지 않고 치간이 개를 폐쇄시키는 것은 심미치과학에서 도전적 과제 중 하나이다. 전치부 수복치료의 성공 여부는 연조직과 경조직간의 심미적인 연합에 달려있다. 이번 증례에서는 치은-치아 계면에서 자연스러운 외형을 가지는 출현윤곽(emergence profile)을 형성하여 줌으로써 치은의 재생 과정이 일어나 심미적으로 만족스러운 치간이개 폐쇄를 이루어내었기에 이를 보고하는 바이다.

At present, the elderly population in Korea is 14% of the total population and then We has entered an the society of advanced age. Along with this, elderly people with dementia and palsy are also increasing. The demand for elderly nursing homes for elderly people with severe diseases such as dementia and stroke is also increasing, and the existing buildings are being secured by Conversion of existing buildings. However, it is difficult to evacuate and fire due to the out of date of buildings by Conversion of existing buildings. For example, there is a fire in the Indukukwon, Pohang City and Hyosung Geriatric Hospital, Jangseong in Korea, which have changed the use of existing buildings. Many elderly people died in a night fire. It was because of the sandwich panel walls and PVC flooring material produced toxic gas instantly. In this study, we investigated the nursing home that changing the use and established fire prevention of human injury and countermeasure of evacuation. First, the sandwich panels which leading to deaths due to the toxic gas were installed in most nursing home. We recommend the RC, the masonry wall, and the glass fiber panel instead of the sandwich panels, In addition, the PVC flooring is most used in nursing home, the flooring material is considered such as the building stones, the tile, and the yellow soil closing instead of the PVC flooring. Second, we investigated the installation status of fire fighting equipment. As a result, the automatic-emergency open&shut equipment, the smoke ventilator and the evacuation slide were rarely installed. In order to secure the golden time in case of fire and to prevent the asphyxia caused by the toxic gas, the law should be amended to install the equipment.

Japanese welfare legislation for the disabled was enacted via Law 283 on December 26. 1956. The push for such legislation at the national level had gown concurrent with development of Japan's post-war economy Korean welfare law for disabled was made 22 years later and was again amended in 1989. The current legislation promotes and supports the legal welfare of the Koran disabled. The following are the results of a comparison between Korean and Japanese accessibility facilities and welfare law; 1) Japan's developement of disabled people's welfare law is inextricably linked to the development of disabled people's advocacy and the human rights movement. In addition, welfare policy has shifts its mandate from rehabilitation to independent living. It follows that local altitudes will play a pivotal role in further policy initiatives. Korean disabled people's welfare policy emerged hand in hand with economic recovery and development following the Korean War. By 1977 a special education law was enacted which-like it Japanese counterpart-promoted the education of disabled children. 2) Accessibility facilities were developed privately movement. The disabled faced constant and systematic disadvantages in public/private buildings and transportation systems. A general lack of cultural awareness and information relating ti these problems prevailed. These included-hut were by no means limited to sign language (for hearing the impaired) and braille(the language of blind). However, new attitudes and improvements have since emerged and new laws have resulted in the publication of Korean 'White Book' outlining the everyday problems faced by the disabled. In addition, mort convenient access facilities have been constructed in public and private buildings. In closing, legal support for the disabled, senior citizens and pregnant women continues to be improved by newer legislation enacted tin April 6, 1977.
