  • The vibration characteristics of a hammer press are important parameters for machine design and production control. In this study, a counterblow hammer press was mathematically modelled as a mass-spring-damper system in order to analyze its vibration characteristics. The forging efficiency was theoretically derived as a function of the mass ratio, momentum ratio, and the coefficient of restitution And the effects of the mass ratio, momentum ratio and the restitution coefficient on the forging efficiency were also investigated for two particular cases of the unit mass ratio and unit momentum ratio. Additionally, the vibration responses of the counterblow hammer press due to the ram colliding impact were analyzed, and the force transmitted to the foundation through the mounting unit was determined.

  • The restitution of cultural heritage located abroad has been going on for 107 years, starting with the return of the Jigwangguksa Tower to Beopcheonsaji Temple in Wonju after it was taken during the Japanese occupation in 1915. The Overseas Cultural Heritage Foundation, established in 2012, has laid the foundation for retrieval, preservation, restoration, and exchange of cultural heritage through research cooperation and the purchasing of cultural heritage items. The pace of the collection of cultural heritage objects and the locating of others has increased every year since its establishment, and the number of returned, rather than recovered, cultural heritage items has also increased. The present study aimed to complete a value inquiry of the cultural relics of Waryongmae (臥龍梅) and a restitution of cultural heritage as the main focuses. The process of recovering relics from Waryongmae has been recorded in the book The Cultural Property Returned into Our Arms, published by the above-mentioned foundation. This record was revised and supplemented to try and raise its cultural value by adding elaborate storytelling to the process of recovering the Waryongmae that grew in the courtyard of Changdeokgung Palace. The cultural value of Waryongmae is that it is unique. The Waryongmae is the first living cultural heritage, and therefore has cultural value due to its uniqueness. Second, the Waryongmae has unique cultural value due to its restitution and return to Korea twice, once in 1992, and another time in 1999. The first restitution was special in that it was featured by the Japanese media, and the second was special in that it was intensively reported by the Korean media. Third, 42 Waryongmae cultural content types were explored, including nineteen visual contents, eleven interactive contents, and twelve skate contents.

  • Purpose: This study was conducted to investigate the mechanical and physical properties of a Korean red pepper variety for particle behavior analysis. Methods: Poisson's ratio, modulus of elasticity, shear modulus, density, coefficient of restitution, and coefficient of friction were derived for "AR Legend," which is a domestic pepper variety. The modulus of elasticity and Poisson's ratio were measured through a compression test using a texture analyzer. The shear modulus was calculated from the modulus of elasticity and Poisson's ratio. The density was measured using a water pycnometer method. The coefficient of restitution was measured using a collision test, and the static and dynamic friction coefficients were measured using a inclined plane test. Each test was repeated 3-5 times except for density measurement, and the results were analyzed using mean values. Results: Poisson's ratios for the pepper fruit and pepper stem were 0.295 and 0.291, respectively. Elastic moduli of the pepper fruit and pepper stem were $1.152{\times}10^7Pa$ and $3.295{\times}10^7Pa$, respectively, and the shear moduli of the pepper fruit and pepper stem were $4.624{\times}10^6Pa$ and $1.276{\times}10^7Pa$, respectively. The density of the pepper fruit and the pepper stem were $601.8kg/m^3$ and $980.4kg/m^3$, respectively. The restitution coefficients between pepper fruits, pepper stems, a pepper fruit and a pepper stem, a pepper fruit and plastic, and a pepper stem and plastic were 0.383, 0.218, 0.277, 0.399, and 0.148, respectively. The coefficients of static friction between pepper fruits, pepper stems, a pepper fruit and a pepper stem, a pepper fruit and plastic, and a pepper stem and plastic were 0.455, 0.332, 0.306, 0.364, and 0.404, respectively. The coefficients of dynamic friction between a pepper fruit and plastic and a pepper stem and plastic were 0.043 and 0.034, respectively.

  • This study is concerned about the impact type damper for effectively restraining the high vibration amplitude in the resonance regions. The theoretical analysis is based on the assumption that the impacts occur twice per cycle at an equal time interval. Simple but reasonable approximations have been derived for the optimum collision clearance and maximum amplitude ratio. Using the impact dampers which is rigidly attached to the primary vibration system, we have experimented for mass ratios and restitution coefficients. The experimental results are in good agreement with theoretical results.

  • This article attempts to describe and analyze discussions on the matter of ex tunc effect or a ex nunc effect of rescission under Korean law in comparison with those under the CISG). In addition, it tries to scrutinize the various rules on the right to damages as an effect of rescission in a comparative way. Furthermore, it compares the various rules of Korean law with the CISG as to the right to damages and evaluates them in light of the discipline of comparative law. It maintains that the liquidation theory in Korean law is more close to the CISG in that there is no ex tunc effect in rescission and in other aspects. It also argues that the construction of the effects of rescission in accordance with the liquidation theory is more plausible when one considers Korea is one of the contracting states of the CISG. In addition, the theoretical analysis and the comparative study with the CISG shows that the insistence of ex nunc effect and its interpretation on the scope of damages extends to damages for expectation interest. It is also submitted that the position under the CISG on the assumption of ex nnuc effect, is regretted in that the restitution in value of the goods in the event of impossibility of the physical restitution is not allowed in some cases which the damage claims can not be awarded for the seller due to the application of the CISG Art. 79.

  • The traffic accident is the prerequisite of the traffic accident reconstruction. In this study, the traffic accident (forward collision) and traffic accident reconstruction (inverse collision) simulations are conducted to improve the quality and accuracy of the traffic accident reconstruction. The vehicle and tire models are used to simulate the trajectories for the post-impact motion of the vehicles after collision. The impact dynamic model applicable to the forward and inverse collision simulations is also provided. The accuracy of impact analysis for the vehicular collision depends on the accuracy of the coefficients of restitution and friction. The neural network is used to estimate these coefficients. The forward and inverse collision simulations for the multi-collisions are conducted. The new method fur the accident reconstruction is proposed to calculate the pre-impact velocities of the vehicles without using the trial and error process which requires the repeated calculations of the initial velocities until the forward collision simulation satisfies with the accident evidences. This method estimates the pre-impact velocities of the vehicles by analyzing the trajectories of the vehicles. The vehicle slides on a road surface not only under the skidding during an emergency braking but also under the steering. A vehicle over steering or cornering with excessive speed loses the traction and leaves tile yaw marks on the road surface. The new critical speed formula based on the vehicle dynamics is proposed to analyze the yaw marks and shows smaller errors than ones of the existing critical speed formula.

  • Development Charge System was introduced in 1989 to recapture development gains, however, it has been revised more than 20 times since then. The reason for such frequent revisions was that estimating development cost was too composite and indefinite. Therefore it is required that estimating method of development cost should be simplified in order to minimize conflicts among diverse parties. To support the recent revision of 'Restitution and Development Gains Act', this study verified several alternatives of applying standardized costs per area under specific size of development and suggested policy implications. For analysis data, 9,362 Development Charge and cost data of si gun gu for recent 3 years were used. The results showed that dividing Seoul Metropolitan Area (SMA) and non-SMA made a significant difference and definite divisions among regional groups. The result of this study could minimize social conflicts as well as contribute in realizing the public concept of land policy by revising Development Charge System.
