Background: Dental injury as a result of oroendotracheal intubation during general anesthesia is very common. We report our experiences of using mouthguard to prevent dental injury during intubation based on our protocol. Methods: This retrospective study enrolled patients referred for preanesthetic evaluation, those patients with a history of any of the dental treatments to their anterior teeth listed on our fabrication protocol from January 1, 2009 to June 30, 2010. Results: No cases of dental trauma during oroendotracheal intubation were reported among the 202 patients who used a protective device. 66% of the patients had risk factors for hard tissue damage aged 10-40 years. At the ages of 40-70 years, the incidence of risk group for periodontal damage was higher. Conclusions: Preanesthetic consultation was effective for preventing dental injury, so preanesthetic questionnaire and proper dental consultation would be helpful.

표재성 방광암의 치료는 경요도적 절제술 후 방광내 BCG 투여가 표준적인 치료로 알려져 있다. 방광내 BCG 투여 후 가장 흔한 부작용은 방광자극, 빈뇨감, 배뇨 곤란 등이며 항결핵제를 사용해야 할 정도의 전신적인 부작용은 5% 이하로 알려져 있다. 저자들은 표재성 방광암 환자에서 경요도적 절제술 후 방광내 BCG 주입치료 후 폐합병증이 발생한 2예를 경험하여 문헌고찰과 함께 보고하는 바이다.

The zeroth-order general Randić index ⁰R_α(G) of the graph G is defined as ∑_u∈V(G)d(u)^α, where d(u) is the degree of vertex u and α is an arbitrary real number. In this paper, the maximum value of zeroth-order general Randić index on the graphs of order n with a given clique number is presented for any α ≠ 0, 1 and α ∉ (2, 2n-1], where n = |V (G)|. The minimum value of zeroth-order general Randić index on the graphs with a given clique number is also obtained for any α ≠ 0, 1. Furthermore, the corresponding extremal graphs are characterized.

A characteristic imaging finding in cases of methanol intoxication is putaminal necrosis, but its presence is usually not suspected due to its rarity. Methanol intoxication generally produces serious neurological symptoms that include visual disturbances and diminished consciousness, characteristically with metabolic acidosis. We reported the case of a 59-year-old man who was admitted to the hospital with diminished consciousness. Acute methanol intoxication was determined as the cause. Laboratory tests revealed high anion gap metabolic acidosis. Diffusion-weighted MRI indicated diffuse symmetric diffusion restriction lesions in the subcortical white matter of both cerebral hemispheres.

Introduction: Numerous countries have launched campaigns regarding sun protection in the last decades. Aim: The aim of the present study was to assess an intervention program aimed at higher knowledge and healthier attitudes regarding sun protection. Materials and Methods: The sample consisted of 4,133 students aged 8-12 years from a single Greek province. Results: In most items, knowledge levels after the intervention were found to be higher than those before ($2.8{\pm}0.9$ vs $3.3{\pm}0.9$), while knowledge about sun protection factors seems to have had the highest improvement (27.1% vs 56.6%). However, student attitudes did not appear to improve, with the exception of applying sunscreen with a higher SPF (29.7% vs 54.8%). Girls seemed to have healthier attitudes compared to boys, but gender played no role with regard to knowledge levels. Also, place of residence did not play any role regarding knowledge levels, although those living in semi-urban areas seemed to have more unhealthy attitudes. Logistic regression by correlating knowledge and attitudes established that higher knowledge levels are usually accompanied by healthier attitudes, albeit marginally. Conclusions: The intervention had a positive contribution to the student knowledge level regarding sun protection and also led to small improvements regarding some attitudes. Continuous similar interventions could lead to better results and the adoption of healthier attitudes.

The purpose of this study was to compare Grit, failure tolerance and psychological well-being between elementary science gifted and general students. The subjects of this study were 48 science gifted students and 70 general students in the 5th and 6th grade of elementary school in Gyeonggi province. The results of this study were as follows: First, Grit, failure tolerance and psychological well-being of science gifted students were higher than those of the general students, there was a statistically significant difference. Second, science gifted students showed higher correlation between grit and failure tolerance, grit and psychological well-being than general students. Grit of science gifted students had a positive correlation with all sub-factors of academic failure tolerance and psychological well-being. In general students, there was a positive correlation with all sub-factors of Grit, academic failure tolerance, and psychological well-being except for the emotion sub-factor of academic failure tolerance. Thirdly, as a result of the regression analysis on the elements of failure tolerance affecting the Grit, science gifted students showed emotional factor but general students had behavioral factors. Also, as a sub-factor of psychological well-being on Grit, both science gifted and general students showed autonomy.

Purpose: The purpose of this study was to identify risk factors for pediatric inpatients falls. Methods: The study was a matched case-control design. The participants were 279 patients under the age of 6 who were admitted between January 1, 2004 and December 31, 2009. Through chart reviews, 93 pediatric patients who fell and 186 ones who did not fall were paired by gender, age, diagnosis, and length of stay. Five experts evaluated the 38 fall risk factors selected by the researchers. Results: In a general hospital, pediatric patients with secondary diagnosis, tests that need the patient to be moved, intravenous lines, hyperactivity, anxiolytics, sedatives and hypnotics, and general anesthetics showed significance for falls on adjusted-odds ratios. Conditional logistic regression analysis was performed to elucidate the factors that influence pediatric inpatient falls. The probability of falls increased with hyperactivity and general weakness. Patients who didn't have tests that required them to be moved and intravenous line had a higher risk of falls. Conclusion: These findings provide information that is relevant in developing fall risk assessment tools and prevention programs for pediatric inpatient falls.

In this study, heat collecting performance was study of flat plate solar collector by the angle. A method of study on were made turn out artificial sun by the angle of 0, 15, 30 degrees. The heat performances were measured the tube array surface temperature by thermo-couple. The winter season natural condition for 4 times on the angles of various general and emboss glass at optimum distance(0.68m) calculated of between sun and solar collector. To sum up temperature rise is appear more or less that emboss glass is all the better for general glass. The temperature variable at below of 30 degree was appear very less. The maximum performance of this system at that it is tilt angle of 30 with general glass is appear Q:11.54(kcal/min) and ${\Delta}T=18.9^{\circ}C$.
