The purpose of this study was to analyze the dental treatment of patients with disabilities, especially according to the frequency of general anesthesia, and to propose the improvements in oral care. The subjects of the present study were 85 patients including age, sex, medical condition, dental treatment and the number of general anesthesia. The patients were divided into regular and irregular check groups according to their follow-up patterns. These two groups were compared for the frequency of general anesthesia and the type of repeated treatment. The results showed that restorative treatment was superior in numbers under first visit of general anesthesia. And more general anesthesia was performed in the irregular recall check group compared with the regular recall check group. This survey suggest that easy access to a dental clinic and the convenience of treatment is needed. On the other hand, there is a time limit on the dental care for disabilities by the dentist. Therefore oral care training program should be simultaneously provided for parents to improve the efficiency of dental care at home. In conclusion, efforts should be made for more comprehensive and effective dental care including regular recall check and preventive home care for disabilities.

The chemistry has the academic system in which a concept is jointly developed into the single strain, so the contents of the chemistry I II of the high school are very important in the connection of the general chemistry in the university. At this moment, it is possible for high school graduates to be accepted into science or engineering majors without taking the chemistry II. These the highest intensive election subject cause problems of differences in level of understanding and difficult of quality educations. In this study, we have analyzed similarity between the contents of the chemistry I II and the general chemistry. We also analyzed the cognition level of students without taking the chemistry II in understanding the general chemistry level classes. We found that the high school level chemistry I and II introduced about 27% and 62% of the essential concepts required for the general chemistry, respectively. In a case of M university in Chonnam, about 70% of students in the general chemistry classes have no exposure to the chemistry II in their high schools, causing difficulty of understanding new subjects due to their insufficient concepts for classes. The lack of knowledge caused lowering of learning achievement and decrease of interests in chemistry.

Background: In South Korea, the number of cases of dental treatment for the disabled is gradually increasing, primarily at regional dental clinics for the disabled. This study investigated pediatric patients at a treatment clinic for the disabled within a university hospital who received dental treatment under general anesthesia. This data could assist those that provide dental treatment for the disabled and guide future treatment directions and new policies. Methods: This study was a retrospective analysis of 263 cases in which patients received dental treatment under general anesthesia from January 2011 to May 2016. The variables examined were gender, age, reason for anesthesia, type of disability, time under anesthesia, duration of treatment, type of procedure, treatment details, and annual trends in the use of general anesthesia. Results: Among pediatric patients with disabilities who received dental treatment under general anesthesia, the most prevalent age group was 5-8 years old (124 patients, 47.1%), and the primary reason for administering anesthesia was dental anxiety or phobia. The mean time under anesthesia was $132.7{\pm}77.6min$, and the mean duration of treatment was $101.9{\pm}71.2min$. The most common type of treatment was restoration, accounting for 158 of the 380 treatments performed. Conclusions: Due to increasing demand, the number of cases of dental treatment performed under general anesthesia is expected to continue increasing, and it can be a useful method of treatment in patients with dental anxiety or phobia.

The purpose of this study is to investigate the university academic achievements on the high school graduates of specialized vocational high school and general high school selected by the university admissions officer system. The implications of this study will contribute to improve development of university admission through the analysis of university admission achievements and correlation between university admission factors and university academic achievements. Participants of this study were university students selected by admission officer system in 2011 and have enrolled in the university for 6 semesters at A university. The results of this study are as follows: First, when it comes to the grades of university admission factors, graduates from specialized vocational high school outperformed those from general high school. Second, when it comes to the correlation between university academic achievements and university admission factors, graduates from specialized vocational high school slightly outperformed those from general high school. Third, when it comes to the correlation between university academic achievements and university academic achievements, graduates from specialized vocational high school showed poorer performance than those from general high school in overall courses and liberal arts courses. However, in major courses, graduates from specialized vocational high school outperformed those from general high school. Finally, when it comes to the development of university academic achievements, both of them showed a tendency of being improved as they advanced through school. Based on the findings of this study, several implications can be made as follows: First, it is necessary to improve the application ratio and application method of university admission factors. Second, it is required to provide preparatory courses of university to help graduates from specialized high school get adapted to university course of study.

Background Although plastic surgeons daily encounter various facial tumors in the field, reports limited on face are scarce. In our study, we want to provide basic epidemiologic data to help clinicians to decide the proper management for their patients. Methods We retrospectively reviewed the medical records of patients including age and gender, location and size of the tumor, histopathologic result, recurrence, type of anesthesia and any associated disorders who had undergone a surgical removal of their facial tumors and received the histopathologic report in the same institution between January 2009 and October 2012. Results One hundred eighty-nine patients with 203 non-melanocytic benign tumors were included. The most frequent site of tumors was the central subunit of the forehead, followed by the lateral subunit of the cheek and the auricular unit. Of 36 different histopathologic results, the epidermal cyst was most frequent, followed by lipoma, pilomatricoma and osteoma. Statistical analysis showed that males were dominant in the epidermal cyst and lipoma groups. While, females were dominant in the osteoma and pilomatricoma groups. No associations were found between lesions and other diseases. Conclusions Our study is the at most specific and concentrated study on non-melanocytic benign tumors of the face. We expect the epidemiologic data of our study may help plastic surgeons who are confronted with so many facial lesions in the field to decide on the most proper management for their patients.

Background: This study retrospectively investigated outcomes following dental implantation in patients with special needs who required general anesthesia to enable treatment. Method: Patients underwent implant treatment under general anesthesia at the Clinic for the Disabled in Seoul National University Dental Hospital between January 2004 and June 2017. The study analyzed medical records and radiographs. Implant survival rates were calculated by applying criteria for success or failure. Results: Of 19 patients in the study, 8 were males and 11 were females, with a mean age of 32.9 years. The patients included 11 with mental retardation, 3 with autism, 2 with cerebral palsy, 2 with schizophrenia, and 1 with a brain disorder; 2 patients also had seizure disorders. All were incapable of oral self-care due to serious cognitive impairment and could not cooperate with normal dental treatment. A total of 27 rounds of general anesthesia and 1 round of intravenous sedation were performed for implant surgery. Implant placement was performed in 3 patients whose prosthesis records could not be found, while 3 other patients had less than 1 year of follow-up after prosthetic treatment. When the criteria for implant success or failure were applied in 13 remaining patients, 3 implant failures occurred in 59 total treatments. The cumulative survival rate of implants over an average of 43.3 months (15-116 months) was 94.9%. Conclusion: For patients with severe cognitive impairment who are incapable of oral self-care, implant treatment under general anesthesia showed a favorable prognosis.

Objective : Aneurysmal rebleeding is a major cause of death and disability. The aim of this study is to investigate the incidence of rebleeding, and the factors related with patient's outcome. Methods : During a period of 12 years, from September 1995 to August 2007, 492 consecutive patients with aneurysmal subarachnoid hemorrhage (SAH) underwent surgery at our institution. We reviewed the patient's clinical records, radiologic findings, and possible factors inducing rebleeding. Also, we statistically analyzed various factors between favorable outcome group (FG) and unfavorable outcome group (UG) in the rebleeding patients. Results : Rebleeding occurred in 38 (7.7%) of 492 patients. Male gender, location of aneurysm (anterior communicating artery) were statistically significant between rebleeding group and non-rebleeding group (p=0.01 and p=0.04, respectively). Rebleeding occurred in 26 patients (74.3%) within 2 hours from initial attack. There were no statistically significant factors between FG and UG. However, time interval between initial SAH to rebleeding was shorter in the UG compared to FG (FG=28.71 hrs, UG=2.9 hrs). Conclusion : Rebleeding occurs more frequently in the earlier period after initial SAH. Thus, careful management in the earlier period after SAH and early obliteration of aneurysm will be necessary.

This study was designed to evaluate the phonological characteristics in profound hearing-impaired children. 10 males and 10 females participated in this study and all were prelingually hearing impaired. 7 children were educated at deaf school and 13 children at general elementary school with private clinic. Their hearing levels were more than 95dB HL and did not appear any wave by ABR. The results can be summarized as following: The articulation accuracy of hearing impaired children was 54.19% and most distinguished phonological patterns of the hearing impaired children were alveolarization and stop assimilation. The accurate articulation phonation was significantly different from education system between deaf school and general school. The error articulation degrees in profound hearing impaired children at general school seemed meaningfully smaller than those in hearing impaired children at deaf school.
