The growth of ICT within the society has
become increasingly digitized, thus, the overall activity has amounted to various
researches for protecting any data from malicious threats. Recently, ransomware
has been a rapidly propagated subject for social engineering techniques
especially the ransomware. Users can delete a ransomeware code using an
antivirus software code. However, the encrypted data would be impossible to
recover. Therefore, ransomware must be prevented and must have early detection
before it infects any data. In this paper, we are proposing a quantification model
to prevent and detect any cryptographic operations in the local drive.
A study was performed to evaluate effects of elastic energy stored pre-stretch on the mechanical work output while performing vertical jump. Eight male volunteers of age between 21-29 years old participated in the present study. The present study hypothesized that the vertical jump height during countermovement jumps (CMJ) would be higher than that during squat jump (SJ). During squat jump, a volunteer paused 0.5 sec before making upward movement. The results showed that ground reaction forces and vertical jump displacements were higher in CMJ in comparison to SJ. The study concluded that part of the positive work measured did derive from the recoil of the elastic component of the muscle-tendon complex.
The purpose of this
study was to suggest the measures and methods for securing the stability of
temporary bridges by analyzing the cause for the collapse of the temporary
bridge built for the construction of the GunNam flood control reservoir located at the main channel
of the Im-Jin River. Numerical simulations (one-, two-, and three-dimensional)
were performed by collecting field data, and the results showed that the
collapse occurred because the height of the temporary bridge was lower than the water
level at the time of the collapse. Also, the drag force calculation showed that
when the guardrail installed on the upper deck structure was not considered,
there was no problem as the calculated values were lower than the design load,
whereas when the guardrail was considered, the stability was not secured as the
were higher than the design load, 37.73 kN/m. It is thought that the actual
force of the water flow applied on the bridge increased due to the accumulation of
debris on the guardrail as well as the upper deck.
To improve competitiveness of a
manufacturing company through enhanced experience values of customers, service
elements are added to a product. The servitization process could take many
different routes reflecting various properties of the manufacturing firm and
its business contexts. A comprehensive servitization process of the high-level
strategy decision and the low-level specific product-service systems design
method have been developed at the Service Design Institute of Sungkyunkwan
Universty. The servitization case of a small furniture manufacturing company is
described in this paper to demonstrate the utility of the servitization method.
