Background: Intravenous sedation is effective for dental patients who are anxious. Recently, target-controlled infusion (TCI) has begun to be used widely to administer and titrate propofol and remifentanil during sedation. To investigate the effect and safety of the pharmacologic agents used in anesthetic department, we performed a retrospective study. Methods: Retrospective study of a series of dental procedure under intravenous sedation performed in department of anesthesiology in Dental Hospital of Dankook University was carried out with propofol or propofol/remifentanil between January and August 2011 and January and April 2012. All patients received oxygen by nasal cannula. The average propofol and remifentanil target was 0.5 ${\mu}g/ml$ and 1.0 ng/ml, respectively using a TCI pump. The average peripheral oxygen saturation ($SpO_2$), heart rate, blood pressure, respiratory rate, nasal end-tidal $CO_2$ were recorded at 5-10 minute intervals. The age, gender, weight, procedure and sedation time, type of procedure were also recorded. Results: We included 22 cases of 19 adults (group A) and 6 cases of children (group B). In group A, 4 patients received propofol (group A-P), and 15 patients received propofol with remifentanil (group A-PR). In group B, 6 patients received propofol only. The mean age of group A was 41.1 years old and that of group B was 9.5 years old. No clinically significant complications were noted. There were no case of de-saturation <90%. The median respiratory rate was 13.1 (range 6 to 36) in group A and 19 (range 13 to 25) in group B. The median end tidal $CO_2$ was 36.7 mmHg(range 8 mmHg to 56 mmHg) in group A and 41.7 mmHg (range 30 mmHg to 53 mmHg) in group B. Conclusions: Based on our results, dental sedation using propofol/remifentanil in adult and propofol in children with TCI pump seems to appear as a safe and effective procedure while performing dental procedure.

Green dietary education emphasized environmental protection and humanity being conducted in middle schools. To develop effective green dietary education program for adolescents, the factors that affected their green dietary practices has been identified. This study aims to identify psychological factors that drive green dietary practices and effect of dietary education that targets middle school students. Data was collected twice from 242 middle school students in Daegu using a self-administered questionnaire in March and June, 2014. There were significant differences in school achievement, economic level and allowance a month (p<0.05) in the green dietary practices and efficacy of students. Three areas (environment, health and traditional, and appreciation & consideration) which were subgroups of green dietary practices were associated with factors such as family relations, peer relationships, self-competence of self-esteem (p<0.05), and positive and negative feelings of happiness (p<0.001). Green dietary practices efficacy was significantly affected by family relations, peer relationships, self-competence of self-esteem (p<0.05), and positive feeling, negative feeling, and negative relationships of happiness (p<0.001). After green dietary education, interests in green dietary, green dietary practices score, the score of health and environment factors of green dietary practices efficacy significantly higher than before education (p<0.05), but all the factors of self-esteem and happiness did not have any significant changes. This study suggests that green dietary education programs for middle school students could account for psychological factors such as self-esteem, happiness according to gender, school records, economic level and allowance a month to be effective.
Purpose: This study was to assess clinically the incidence of abutment screw loosening of posterior implant-supported fixed prosthesis and its affecting factors. Materials and methods: 391 implant-supported crowns restored from January 2013 to January 2016 were included in this study. All restorations were fabricated with either a single crowns or a splinted crown, and cemented with temporary cement. The incidence of abutment screw loosening is investigated and gender, restoration position, opposing teeth, restoration type, abutment connection type were assessed as possible factors affecting abutment screw loosening. Results: During the observation period (2 - 5 years), abutment screw loosening was found in 29 restorations (7.4%). It took 3 to 48 months (means 19.5 months) to loose the screw, and three of these implants were fractured. Among the factors considered, there were statistically significant differences at abutment screw loosening rate between molar group (9.4%) and premolar group (2.6%) (P<.019). According to the type of opposing teeth, there were statistically significant differences between nature teeth (74.7%) and implant (25.0%), removable denture (3%) (P<.019). The other possible factors did not have a significant effect on loosening of the abutment. Conclusion: The incidence of abutment screw loosening in posterior restoration was 7.4%. Abutment screw loosening were more likely to occur in molars group than premolar group, and according to the opposing teeth, there were the greatest frequency in nature teeth than implant and removal denture. There was a statistically significant difference.

As category that influence in science attitude, in elementary school were gender, area and grade, in middle school were grade and area, and in high school was area.
The objective of this study was to evaluate the effect of exogenous ghrelin on the behaviors, weight gain, and feed intakes of weanling piglets. A total of 25 pairs of Duroc$\times$Landrace$\times$Large White piglets weaned at 21 days of age were used in this experiment which finished on day 36. Each pair of healthy piglets from the same litter with similar body weight and of the same gender were selected and randomly arranged to ghrelin or control groups. Thus, there were 50 piglets (ghrelin 25; control 25) kept in 10 pens (ghrelin 5; control 5) and 5 piglets per pen. Initial body weight of the pigs did not differ between the control and ghrelin treatment ($7.43{\pm}0.17kg$; p = 0.81). Experimental pigs were infused with ghrelin ($1{\mu}g/d$ pig) via the marginal ear vein between 0750 and 0800 h at 22, 23, 24 days of age. Control pigs were infused with 0.9% saline. Feed consumption was measured on days 23, 24, 25, 29 and 36. Body weight was measured on days 22, 23, 24, 25, 29 and 36. Behavior data of individual piglets were collected by real-time observation from 0800-1500 h through remote supervisory equipment at 22, 23 and 24 days of age. The results indicated that ghrelin infusion could increase drinking (p<0.05) and lying behaviors (p<0.01) and decrease mounting behaviors (p<0.05). No significant influence of ghrelin was found on average daily weight gain (ADG) and average daily feed intake (ADFI) in this experiment (p>0.05). In conclusion, exogenous ghrelin by the method above and at the dosage of $1{\mu}g/d$ pig could cause a variety of behavioral effects, but not improve performance of weanling piglets.

The Farm-Closure Assistance (FCA) program is operated to compensate for lost farm income, to stabilize the management of low-competitive farms, and to enhance competitiveness of target items. The FCA, however, has several problems, such as the balloon effect and fraudulent receipts. Therefore, it is important to examine the operational problems of the FCA, establish improvement plans, and settle the measures. The objectives of this study are to analyze problems and suggest solutions for FCA, reflecting the viewpoints of local government officials who are in charge of actual tasks on the FCA front lines. The study analyzes whether characteristics of government officials lead to differences in setting the maximum amounts and extensions to FCA. Factors influencing the necessity of setting ceilings on FCA were work experience, recognition of agriculture's importance, and the FTA's impact on domestic agriculture, gender, and regions. Factors affecting the extension of FCA were the agency unit, work experience on the FTA, recognition of the effects of FTA direct payments and FCA, and recognition of the subsidy's direction. The results can be employed as a fundamental background that can set the direction for institutional improvement when the government tries to improve FCA.
