Non-interlayer hybrid white organic light-emitting diodes via a bipolar mixed host for the blue-fluorescent-emitting layer

권용원,이창희 한국정보디스플레이학회 2017 Journal of information display Vol.18 No.4

The reduction of the interlayer in hybrid white organic light-emitting diodes (WOLEDs) provides a potential for improving the device efficiency. Reported herein are non-interlayer hybridWOLEDsprepared using a mixed host for the blue-fluorescent-emitting layer. The proposed device exhibits high efficiency with the maximum external quantum efficiency up to 17.1%, and stable colors. Moreover, the effect of the interlayer on the device lifetime was demonstrated.

Long-term successful function of a dental implant depends upon biocompatibility of the implant system. Heavy stress may induce the resorption of alveolar bone. Stress analysis using three-dimensional finite element method was applied to compare and analyze the stress produced in adjacent bony tissue and various dental implants. Seven models (Screw type * length 13mm, diameter 3.75mm, 4.0mm, Cylinder type : length 13mm, diameter 3.3mm, 4.0mm, Hollow-basket type • length 13mm, diameter 3.5mm, 4.5mm, 5.5mm) were designed. 10kg of static load was applied to each experimental model. The results were as follows. 1. All the tested implant models showed maximum stress at the cervical portion of the implant with relatively wide and large stress distribution at the apical portion. 2. Heavy shear strength was demonstrated at the cervical portion in screw type 4.0mm and at the apical portion of cylinder type and hollow-basket type implants, indicating an intimate relationship with the shape and diameter of implant system. 3. Different shapes of implants with the same diameter were to have the different area of stress concentration according with the structural characteristics of implants and screw type implants showed relatively stable pattern of stress distribution when compared to other systems. 4. Implants of identical shape with differnet diameters showed similar stress distribution with slight superiority in those of larger diameters. 5. Under the condition of identical bony tissue, increased diameter beyond a certain point resulted in severe stress concentration. 6. Screw-type implant showed the best stress distribution and selectiong the adequate diameter of implant for the remaining alveolar bone is thought to be critical.

The purpose of this study was to compare the fitness, hardness and bending strength of the conventional reliners and visible light curing reliner. Nine regions were selected in the upper transverse section which were thought to be of interest from a clinical standpoint and the discrepancies between the dentures and the master cast in these regions were determined by the coordinated measuring machine (UMM-500, Zeiss, W. Germany). The results were as follows: 1. The experimental denture bases showed the lowest fitness at the central portion of the posterior palatal border and the intimate contact in the buccal flanges regardlness of relining materials and relining methods. 2. The fitness of relined denture base was the best in autopolymerizing group and in the order of long processing, short processing and visible light curing group. 3. The fitness after 24 hour-storage in water was improved in long processing and autopolymerizing groups, but there was no significant difference. 4. The hardness was the highest in long processing group and decreased in the order of short processing, visible light curing and autopolymerizing group. 5. The bending strength was the highest in long processing group and decreased short processing, visible light curing, and autopolymerizing group in order.

The purpose of this study was to compare the fithness, hardness and bending strength of the conventional reliners and visible light curing reliner. Nine regions were selected in the upper transverse section which were thought to be of interest from a clinical standpoint and the discrepancies between the dentures and the master cast in these regions were determined by the coordinated measuring machine(UMM-500, Zeiss, W. Germany). The results were as follows ; 1. The experimental denture bases showed the lowest fittness at the central portion of the posterior palatal border and the intimate contact in the buccal flanges regardless of relining materials and relining methods. 2. The fittness of relined denture base was the best in autopolymerizing group and in the order of long processing, short processing and visible light curing group. 3. The fittness after 24 hour-storage in water was improved in long processing and autopolymerizing groups, but there was no significant difference. 4. The hardness was the highest in long processing group and decreased in the order of short processing, visible light curing and autopolymerizing group. 5. The bending strength was the highest in long processing group and decreased short processing, visible light curing, and aotopolymerzing group in order.

치과 IMPLANT의 길이차이에 따른 응력 분석의 유한요소법적 연구

Stress analysis using finite element method was applied to compare and analyze stress produced in adjacent bone tissue and dental implants. Experimental models have dental implants in the edentulous area of the first premolar in the lower arch. Six models(Branemark implant : diameter 3.75㎜, length 7㎜, 10㎜, 13㎜, 15㎜, 18㎜, 20㎜) wee designed. 10Kg of static load was applied to each experimental model. The results were as follows. 1. Every implant sample showed maximum stress at the cervical portion and also showed quite largely at the apical portion. 2. The amount of stress among the several implants with variable lengths but same diameter showed many differeces. The shorter one showed the more stress than longer. 3. The longer implant of the same diameter shoed more advantageous in stress relief. 4. the stress distribution of dental implants mainly depend upon their length rather than their diameter.

Long-term successful function of a dental implant depends upon the biocompatibility of the implant material and the biofunctionality of the implant system. Heavy stresses may induced the resorption of alveolar bone. The purpose of this study was to analyze the stress distribution of dental implants with different diameters around the supporting bone. The results were as follows : 1. Maximum stress values developed in the apical portion of each type of implant and the stress in the cervical portion of implant also appeared heavy. 2. In the different kinds of implant with the same length, the Branemark implant showed the lowest value, and Core-Vent and IMZ implant showed the stress value in ascending order. 3. The difference of diameter of the same implant system had little influence on the stress distribution of the same. 4. When the same amount of bone tissues being used, the longer diameter implant showed more stress.
