Purpose: The purpose is to provide basic information for establishing improvements on performance-based pay's evaluation method of health teachers. Methods: For subjects, 200 teachers at public elementary schools and 200 health teachers at public elementary schools in Gyeonggi-do were conveniently sampled, and then surveyed through a questionnaire. The questionnaire was to recognize recognition of teachers working under the teacher's performance-based pay system, which was quoted in the questionnaire of Choi ji-hye (2005) and Lee mi-gyeong (2008). Inquiry for the recognition of teachers on evaluation of health teacher's performance-based pay system and improvements on the performance-based pay's evaluation method of health teachers were used after consultation with five incumbent health teachers and a review with the thesis director. Results: The performance-based pay's evaluation method of health teachers has the same method with general teachers in schools, so it is not fair to evaluate the performance of health teachers. The ways to improve the performance-based pay evaluation method of health teachers is as follows: first, the approval on improving 'the number of class hours' which is a detailed item of a teacher's performance evaluation criterion to 'the number of health lesson hours per week and the number of students visiting the school infirmary per week'; second, improving 'life guidance' into 'counseling results of medically-treated students, parents of students and personal hygiene guidance'; third, improving 'a teacher in charge' into 'awarding of points by being recognized as a health teacher in charge of all students and considering the economic situation of the region,; forth, improving 'difficulty of position' into 'the number of health-teacher's annual promotion task items and the treatment number of issuing and receiving of official documents', and improving the 'task difficulty' into 'importance and urgency of emergency patient management, risk level and urgency of infectious diseases and avoiding work in charge' appeared to be more than 90% respectively. Conclusion: The performance-based pay system of teachers being carried out every year should be executed by preparing fair evaluation criteria suitable for task properties and the role of health teachers with different evaluation criteria compared to general teachers.

The purpose of this study was to analyze the differences in the frequency and importance of basic nursing practice between comprehensive nursing care service wards and general wards and to provide basic data for the efficient of services. The subjects of this study were 99 comprehensive nursing care service and 90 general wards. Data were collected from February 1 to 28, 2018 and analyzed using a t-test, one-way ANOVA, Pearson's correlation coefficient, Scheffe test. The results showed that the frequency of basic nursing practice was higher by 2.43, and there were significant differences in personal hygiene, nutrition and excretion, exercise & activity. The recognition of the importance of basic nursing was high in both groups, but comprehensive nursing care service wards were slightly higher at 4.24 points. However, as the frequency of practice is lower than the recognition of the importance of basic nursing, a method to increase the frequency of practice is necessary. These results suggest that comprehensive nursing care service wards should provide appropriate nursing staff and system development so the nurses can provide care service as professionals.

Oculo-cerebro-renal syndrome, known as Lowe syndrome, is an X-linked gene disorder characterized by congenital cataracts, brain abnormalities and renal dysfunction. Tooth crowding, taurodontism, delayed eruption in the permanent dentition and over-retained primary teeth with ectopic eruption of the permanent teeth have been reported as dental findings. Because of the high incidence of poor cooperation, patients with Lowe syndrome have difficulties in maintaining good oral hygiene, which may require dental treatment. We present a case of dental treatment for the uncooperative child with Lowe syndrome under general anesthesia. A 4-year-old, 11.2 kg boy with Lowe syndrome visited Seoul National University Dental Hospital for gingival swelling. The patient had multiple caries requiring dental treatment. Because of his past history of malignant hyperthermia during inhalation induction, anesthesia was induced and maintained with total intravenous anesthesia (TIVA) after medical consultation. Dental restorative treatments were successfully performed and no complications were observed during and after the procedure. Safe and effective dental management of the patients with Lowe syndrome could be performed with the help of general anesthesia and careful monitoring.

Wolf-Hirschhorn syndrome(WHS) is a congenital disorder caused by deletions of the short arm of chromosome 4. The most common characteristics are mental and growth retardation, dietary disorder and craniofacial features with a characteristic 'Greek warrior helmet' appearance. The dental characteristic of WHS includes delayed development, tooth agenesis, clefts, microdontia, taurodontism, and severely worn dentition. The purpose of this case report is to describe the dental treatment of a patient with WHS. 3-year-old boy with WHS visited the Seoul National University Dental Hospital for dental treatment. He had difficulty with nasotracheal intubation because of craniofacial anomalies and also had poor oral hygiene due to a limitation of mouth opening and dietary disorder. Due to his airway problem, behavior management and severity of dental conditions, dental treatment was performed under general anesthesia. This case suggests general anesthesia can be chosen with WolfHirschhorn syndrome patients to safely care for their dental problems.

Purpose: The aim of this study is to investigate the characteristics of patients and teeth referred to a university dental hospital for endodontic problem. Materials and Methods: From January, 2017 to December, 2018, patients who were referred to a university dental hospital for endodontic problem were collected from clinical records. A total of 1171 patient records were analyzed. The status of the referred teeth was divided into three groups according to whether they were treated endodontically based on radiographs and clinical records at the time of referred visit. Results: 69.9% of the referred teeth were maxillary and mandibular first and second molars. The average time from referral to actual visit is 9.03 days and 65.6% of the case referred with referring letter. The most primary reasons of referral were persistent clinical symptom (pain, swelling, and sinus tract) (37.9%), diagnosis difficulty (16.7%), blockage of canal space (13.8%) and difficult tooth anatomy (11.4%). In the case of referral before endodontic treatment, the most primary reason of referral was failure to make a proper diagnosis. If the teeth were referred in the middle of endodontic treatment, the most primary reason of referral was persistent clinical symptom and blockage of canal space. In the case of referral after root canal filling, the most primary reason of referral was persistent clinical symptom. Conclusion: In the case of molars, the rate of persistent clinical symptom and blockage of canal space were the most primary reason of referral, and the rate of apical surgery and management of trauma was high in the case of anterior teeth.

This study investigates the factors influencing quality of life for cancer patients based on demographic characteristics, physical-mental health, and oral health. These factors are analyzed using the results from 235 cancer patients in Korea's 7th national health and nutrition survey. Data were analyzed using PASW Statistics Ver. 18.0. Studies show that cancer patients experienced stress (74.5%), depression (84.3%), and activity limitations (15.3%). In oral health, problems chewing were often experienced in groups with low incomes (3.35±.21), activity limitations (2.71±.31), and depression (3.01±.27). The factors influencing quality of life were higher by 3.43 times in the low-income group and by 8.39 times in the activity-restricted group, by 2.74 times in the high-stress group, by 4.58 times in the depression group, by 2.68 times in the chewing-problems group, and were 4.92 times higher in the speech problems group (p<0.05). To improve quality of life, not only mental and physical health care, but also oral care is necessary. An integrated management plan for medical staff in the treatment process of cancer patients is required to prevent mental, physical, and oral discomfort.
