The purpose of this study was to examine the effects of the burnout of dental hygienists on their job commitment. The subjects were 156 dental hygienists. Structured questionnaire surveys were conducted. Maslash Burnout Inventory scale and the tool developed by Kang was used. The burnout and job commitment was each divided into three factors; emotional depletion, accomplishment decrease and dehumanizing and organizational commitment, career commitment, and work commitment. The dental hygienists' burnout score was 3.77 points and commitment score was 3.53 points. Burnout was higher among those with clinical careers shorter than five years and smaller numbers of colleague. Those with higher burnout showed higher career involvement and those with longer careers and higher salaries showed higher organizational commitment. Dental hygienists' career that higher burnout was associated with lower degrees of job commitment. Therefore, efficient manpower management should be ways to maintain of their carrer and increase the salary.

The purpose of this study was to investigate the effects of early cognitive training and tailored telephone coaching program for ischemic stroke. Among 28 participants, assigned into the experimental(n=15) and control group(n=13). Only the experimental group was received a 4-week cognitive training and 11 session of tailored telephone coaching. The effect ot the program was evaluated four times(baseline, 4weeks, 8weeks, 12months) using the tool on Depression, Mini Mental State Examination(MMSE), Neuropsychological battery, Activities of Daily Living(ADL). The repeated measures ANOVA showed that the experimental group showed improvement in MMSE, verbal memory and executive function compared to the control group. Especially, the improvement of executive function which is related to ADL was a remarkable result. This suggests that early intervention is very important for recovery cognitive function and independent daliy life after stroke, and periodic telephone coaching should be done together for mid-to long term effects.

Purpose: To compare different radiographic methods for assessing endodontically treated teeth. Materials and Methods: Root canal treatments were applied in 120 extracted mandibular teeth, which were divided into four groups: (1) ideal root canal treatment (60 teeth), (2) insufficient lateral condensation (20 teeth), (3) root canals filled short of the apex (20 teeth), (4) overfilled root canal treatment (20 teeth). The teeth were imaged using intraoral film, panoramic film, digital intraoral systems (CCD and PSP), CCD obtained with portable X-ray source, digital panoramic, and CBCT images obtained at 0.3 $mm^3$ and 0.2 $mm^3$ voxel size. Images were evaluated separately by three observers, twice. Kappa coefficients were calculated. The percentage of correct readings obtained from each modality was calculated and compared using a t-test (p<0.05). Results: The intra-observer kappa for each observer ranged between 0.327 and 0.849. The inter-observer kappa for each observer for both readings ranged between 0.312 and 0.749. For the ideal root canal treatment group, CBCT with 0.2 $mm^3$ voxel images revealed the best results. For insufficient lateral condensation, the best readings were found with periapical film followed by CCD and PSP. The assessment of teeth with root canals filled short of the apex showed the highest percentage of correct readings by CBCT and CCD. For the overfilled canal treatment group, PSP images and conventional periapical film radiographs had the best scores. Conclusion: CBCT was found to be successful in the assessment of teeth with ideal root canal treatment and teeth with canals filled short of the apex.

Purpose: The attachment level is strongly associated with tooth loss and provides useful information on patterns of destruction of the periodontium. The presence of horizontal attachment loss would not be detected in clinical measurement. Therefore, the purpose of the present study was to estimate the patterns of periodontal destruction based on the attachment area and horizontal attachment loss in extracted teeth due to severe periodontitis. Materials and Methods: 307 teeth satisfied the criteria for assessment. An indirect method, based on digital images obtained from a digital camera and an image analysis program, was used to calculate the area of root surface and attachment loss and the extent of horizontal attachment loss. The data were analysed using SPSS. Results: No statistically significant differences among root surfaces were observed in anterior teeth on the loss of attachment area. However, in posterior teeth statistically significant differences in palatal surfaces of maxillary and mandibular premolar and molar surfaces compared with buccal surfaces were observed. Horizontal attachment loss was observed in 21.5% of the teeth examined. Frequency of horizontal attachment loss was highest in the maxillary first premolar (34.8%), followed by the maxillary second premolar (27.3%) and maxillary canine (25%). The mean length of horizontal attachment loss was 1.5mm. Conclusion: More meticulous examination will be needed of the palatal surfaces of maxillary and mandibular premolar and molar teeth. The percentage of teeth with horizontal attachment loss greater than 2.1 mm was 5.2%. Considering the length of curette blades, about 5.2% of teeth were not properly debrided. Therefore, Additional supportive therapy such as local drug delivery has to be considered in treatment of the first maxillary, second premolar and canine due to the high prevalence of horizontal attachment loss.

This study was aimed to evaluate the effects of Cypress oil(CS) on anti-asthmatic activities in a mouse model of allergic asthma. Using an Ovalbumin-induced allergic asthma mouse model, 0.3% of CS was administered to experimental group using a nebulizer for 3 weeks on a basis of 3 times per week and 30min each time. The degree of airway hypersensitivity, the number of eosinophil in white blood cells, the number of immune cells and the change of cytokine in lung tissue were evaluated. The degree of airway hypersensitivity, the number of eosinophil, IL-5 and IL-13 levels in lung tissue, IgE in serum, the number of CCR3, CD3, CD4 cells were significantly decreased in experimental group treated with CS. These results suggested that CS may have a positive effects on Th2 cytokine and eosinophils which are major factors of asthma responses. Therefore CS might be of therapeutic value in treating asthma.
