Pierre Robin syndrome (PRS) is characterized by the triad of congenital mandibular hypoplasia, glossoptosis and cleft palate. Infant PRS patients are frequently suffering from upper airway obstruction, gastroesophageal reflux and growth retardation caused by above mentioned problems. We report a dental caries treatment of 3-year old girl with Pierre Robin syndrome with multiple caries. The cause of multiple caries was mainly presumed as patient's eating habit caused by her general condition. She had some feeding problems and had history of gastric tube. She was still using milk bottle and took more than an hour to finish a meal. The treatment was performed under general anesthesia considering patient's condition; mild autism, poor cooperation and respiratory problem due to micrognathia. Severely affected upper incisors were treated with pulp treatment and restored with zirconia crown for esthetic purpose. Lower incisors were treated with pulp treatment and restored with composite resin. Upper right first primary molar was restored with stainless steel crown and other primary molars were treated with composite resin. There were no postoperative complications. According to her parents, the patient's compliance to oral hygiene management was greatly improved after the treatment since she was very pleased with the esthetic result and highly motivated by her looks. The treatment without sedation or general anesthesia would be possible once the airway is improved as the mandible grows.

Pierre Robin sequence(PRS) is characterized by a triad of clinical signs: micrognathia, glossoptosis and cleft palate. These anatomical deformities of PRS predispose patients to respiratory problems and feeding difficulties at birth. Maintaining oral hygiene and enduring dental treatment are complicated by their general conditions of PRS patients. We present a case of dental treatment of PRS patient under general anesthesia. A 3-year-old boy with PRS visited Seoul National University Dental Hospital for caries treatment. Clinical and radiographic examinations revealed multiple carious lesions. Considering the patient's medical condition and compliance of treatment, dental treatment under general anesthesia was decided. Despite expected challenges of managing the airway of the patient, intubation was performed successfully. The patient was treated with pulp treatments and restorations using composite resin and stainless steel crowns. No complications were observed during and after the procedure.

고준위 방사성폐기물 처분사업은 미 의회 내에서도 골치 아프고 민감한 문제로서 지난 몇 년간 아무 해결책 없이 손을 놓고 있는 상태이다. 교착 상태에 빠져 있는 이 문제는 올해 치러지는 선거가 끝난 후에나 해결책이 나올 수 있을 것으로 전망되고 있다.

There seems to be a love-hate relationship between Brouwer's fixed point theorem and the fundamental theorem of algebra; in this note we offer one more tweak at it, and give a version of Rouches theorem.

For linear operators between Banach algebras "spectral boundedness" is derived from ordinary boundedness by substituting spectral radius for norm. The interplay between this concept and some of its near relatives is conspicuous in a result of Curto and Mathieu.

We discuss the perturbation theory of "left" and "right" Browder operators, which come somewhere between Browder operators and semi Browder operators.
