This article reviewed the literatures which demonstrated correlations between therapeutic relationship variables and treatment outcomes in children and adolescents, and also examined factors which affect a positive therapeutic relationship. Results from this review revealed that a positive therapeutic relationship is essential for cognitive-behavioral treatment (CBT) with children and adolescents, and also indicated that the therapeutic effect is the most powerful when a therapist maintains a collaborative relationship. Finally, basic strategies for maintaining a collaborative relationship have been suggested. These include strategies such as ; 1) setting a goal for therapy focusing on enhanced motivation for therapy ; 2) facilitating the engagement of parents in the treatment process ; 3) creating a collaborative atmosphere ; 4) educating the client about therapy ; 5) liciting feedback ; 6) making creative and innovate modifications of traditional CBT methods ; and, 7) providing choices for the client.

Recently the 2nd generation laboratory composite resins were introduced. Although the mechanical properties of these composite resins have been improved, there were some disadvantages such as discoloration, low abrasion resistance and debonding between metal and resin. The purpose of this study was to evaluate the tensile bond strength between non-pecious dental alloy(verabond) and four veneering reinforced composite resins: Targis(Ivoclar Co.,U.S.A.), Artglass(Kulzer CO., Gemany). Sculpture(Jeneric Pentron Co., U.S.A.), and Estenia(Kurary Co., Japan). All test metal specimens were polished with #1,000 SiC paper, and sandblasted with 250micrometer aluminum oxide. After then, according to manufacturer's instructions metal adhesive primer and veneering resins were applied. All test specimens were divided into two groups. One group was dried in a desiccator at 25degrees C for 3 days, the other group was subjected to thermal cycling(2,000x) in water(5/55degrees C). Tensile bond strength was measured using Instron Universal Testing machine and the fractured surface was examined under the naked eyes and scanning microscope. Within the limitations imposed in this study, the following conclusions can be drawn: 1. in no-thermal cycling groups, there were no significant differences between Estenia and VMK68 but there were significant differences between Targis, Artglass, Sculpture and VMK68(p<0.05). 2. in no-thermal cycling resin groups, the highest tensile bond strength was observed in Estenis and there were significant differences between Estenia and the other resins(p<0.05). 3. Before and after thermal cycling, there were significant differences in tensile bond strength of Targis and Artglass(p<0.05). The tensile bond strength of Artglass was decreased and that of Targis was increased. 4. in no-thermal cycling groups, Artglass showed mixed fracture modes(95%), but after thermal cycling, Artglass showed adhesive fracture modes(75%).

Objective: Although the Clinical Dementia Rating (CDR) scale was originally developed to stage Alzheimer’s dementia (AD), it is now used globally for various types of dementia. The aim of this study was to investigate the characteristic pattern of CDR domains and its association with neuropsychological findings and activities of daily living (ADL) in patients with vascular dementia (VaD) and patients with AD. Methods: We recruited very mild to mild VaD and AD patients who were age-matched among the first visitors to a dementia clinic. All subjects underwent a standardized clinical interview, physical and neurological examinations, and laboratory tests, including brain magnetic resonance imaging, according to the protocol of the Korean version of the Consortium to Establish a Registry for Alzheimer’s Disease assessment battery. Results: A total of 105 pairs of VaD and AD patients participated in this study. Although the adjusted scores on Korean version of the Mini-Mental State Examination were similar between the two groups, the VaD patients performed better on the Boston Naming Test, Word List Memory, Word List Recall, Word List Recognition, and Constructional Recall Test. However, the scores on global CDR, CDR sum of boxes, and ADL-related CDR domains were higher in VaD patients than in AD patients (p<0.001). The VaD patients also showed poor performances on the Disability Assessment for Dementia Scale, Frontal Assessment Battery, Executive Clock Drawing Task, and Stroop tests. Conclusion Despite similar general cognitive function and better memory function, patients with VaD tend to be staged as severer dementia on the CDR scale than patients with AD because of more impaired ADL associated with executive dysfunction.

It is very useful to evaluate the content and 3D distribution of extracellular matrix non-destructively in tissue engineering. This study evaluated the feasibility of using micro-computed tomography (µCT) with Hexabrix to measure quantitatively sulfated glycosaminoglycans (GAGs) of engineered cartilage. Rabbit chondrocytes at passage 2 were used to produce artificial cartilages in polyglycolic acid scaffolds in vitro. Engineered cartilages were incubated with Hexabrix 320 for 20 min and analyzed via µCT scanning. The number of voxels in the 2D and 3D scanning images were counted to estimate the amount of sulfated GAGs. The optimal threshold value for quantification was determined by regression analysis. The 2D µCT images of an engineered cartilage showed positive correlation with the histological image of Safranin-O staining. Quantitative data obtained with the 3D µCT images of 14 engineered cartilages showed strong correlation with sulfated GAGs contents obtained by biochemical analysis (R² = 0.883, p < 0.001). Repeated exposure of engineered cartilages to Hexabrix 320 and µCT scanning did not significantly affect cell viability, total DNA content, or the total content of sulfated GAGs. We conclude that µCT imaging using Hexabrix 320 provides high spatial resolution and sensitivity to assess the content and 3D distribution of sulfated GAGs in engineered cartilages. It is expected to be a valuable tool to evaluate the quality of engineered cartilage for commercial development in the future.

Central neurogenic hyperventilation (CNH) is a rare condition that characterized by an increase in the rate and depth of respiration to an extent that produces advanced respiratory alkalosis due to various central nervous disorder. The mechanism of CNH remains unclear. We reported a case of CNH in patients with progressive ischemic stroke in pons, including parabrachial nucleus, which is thought to have disrupted inhibitory impulses to the medullary respiratory center.
