  • PM OLED has the line-disturbance when eyes can detect the driving line status in the shaking situation. It is closely related with the lighting intensity and the lighting time during the line driving. .In this paper we suggest the frame part method for eliminating lineflash appearance. Frame part is a driving method of PM OLED, which divides one frame into several inner-frame parts to reduce the color interference between closely related pixels and to lessen the lineflash appearance which disturbs viewer to perceive the images. Frame part groups one frame into several inner-frame parts and have inner-frame rate higher than the frame rate. Frame part could be used in most of applications in PM OLED systems to enhance the total performance of screen quality.

  • Based on the test on a 1/2.5-scaled model of a two-bay and three-story inner frame composed of reinforced concrete beams and lattice steel reinforced concrete (SRC) irregular section columns under low cyclic reversed loading, the failure process and the features of the frame were observed. The subsequence of plastic hinges of the structure, the load-displacement hysteresis loops and the skeleton curve, load bearing capacity, inter-story drift ratio, ductility, energy dissipation and stiffness degradation were analyzed. The results show that the lattice SRC inner frame is a typical strong column-weak beam structure. The hysteresis loops are spindle-shaped, and the stiffness degradation is insignificant. The elastic-plastic inter-story deformation capacity is high. Compared with the reinforced concrete frame with irregular section columns, the ductility and energy dissipation of the structure are better. The conclusions can be referred to for seismic design of this new kind of structure.

  • It is necessary for the design of lead frame punches in blanking to consider buckling because inner lead pitch of lead frame has been narrowed by miniaturization and high accumulation of semiconductor. In addition, if process variables change in press stamping process, the lift of punches is no longer influenced in wear and punches can be broken suddenly. To prevent the fracture of fine pitch lead frame punches, having considered applying reinforcement to it, this paper verified the design with buckling analysis. This study presents the optimal position and number of reinforcement to be attached to punches. Finally this study presents design rules of attaching reinforcement.

  • In this paper, cyclic loading tests on composite frame inner joints of steel-reinforced recycled concrete (SRRC) column-steel beam were conducted. The main objective of the test was to obtain the shear behavior and analyze the shear strength of the joints. The main design parameters in the test were recycled coarse aggregate (RCA) replacement percentage and axial compression ratio. The failure process, failure modes, hysteresis curves and strain characteristics of the joints were obtained, and the influences of design parameters on the shear strength of the joints have been also analysed in detail. Results show that the failure modes of the joints area are typical shear failure. The shear bearing capacity of the joints maximally decreased by 10.07% with the increase in the RCA replacement percentage, whereas the shear bearing capacity of the joints maximally increased by 16.6% with the increase in the axial compression ratio. A specific strain analysis suggests that the shear bearing capacity of the joints was mainly provided by the three shear elements of the recycled aggregate concrete (RAC) diagonal compression strut, steel webs and stirrups of the joint area. According to the shear mechanism and test results, the calculation formulas of the shear bearing capacity of the three main shear elements were deduced separately. Thus, the calculation model of the shear bearing capacity of the composite joints considering the adverse effects of the RCA replacement percentage was established through a superposition method. The calculated values of shear strength based on the calculation model were in good agreement with the test values. It indicates that the calculation method in this study can reasonably predict the shear bearing capacity of the composite frame inner joints of SRRC column-steel beam.

  • The purpose of this study is to clarify that 'Kanghosasiga' is the Ynsijo which has general unification of the content and having general unification is based. on the using one definite frame. although 'Kanghosasiga' used different subject matters that have characteristics of four season in forming one theme. The definite frame is divided into two frames, inner frame and outer frame. Outer frame is common in four works, and it represents the place in which the speaker lives(강호), speaker (이몸), relationship between speaker and the king(군은), the condition of 'kangho' and speaker. And in this paper, the generative condition of phrases is so analyzed that the compression and the simplicity of expression are explained, and the purpose of generative phrases is so analyzed that satisfaction at life is represented. It is considered if it is possible to extended to '태평성대(the happy era)' in the social view. Inner frame is the detail structure of content of the work. Each of the first, second, third of the verses of four works have common structure. After analyzing each content, the characteristic of 'Kanghosasiga' was explained. The first of verses of 'Kanghosasiga' represent gusto of the four season. The second is constructed with 'the clause that functions as instruction' because 'speaker' that is the words that functions as index, and represents in detail gusto of the first. The third is connotative expression connected with the second. The third implies purpose that the writer try to gain private living with formal viewpoint. The structure of the inner frame of 'Kanghosasiga' shows a process; 'introducing season' $\to$ 'gusto about season' $\to$ 'enjoying with season' $\to$ 'peace in mind'. The first of verses of 'Kanghosasiga' is the clue of the second. The second is the reaction of the first. The third has character as estimation of the forepart. The structure of the outer frame can be shown if the structure of the inner frame has '감군은‘(being grateful to king's grace). ultimate purpose of the writer is to praise king's administration.
