  • Convergence condition determines performance of iterative learning control (ILC), for example, convergence speed, remaining error, etc. Hence, the performance can be elevated and a feasible set of learning controllers grows if a less conservative condition is obtained. In the frequency domain, the $H_{\infty}$ norm of the transfer function between consecutive errors has been currently used to test convergence of a learning system. However, even if the convergence condition based on the $H_{\infty}$ norm has a clear property about monotonic convergence, it has a few drawbacks, especially in MIMO plants. In this paper, the relation between the condition and the monotonicity of convergence is clarified and a modified convergence condition is found out using a frequency domain Lyapunov equation, which supersedes the conventional one in the frequency domain.

  • 각 교육기관마다 일관성 없는 학과명의 변경은 배움의 당사자들인 학생들에게 교육의 효과 측면에서 긍정적으로 작용하지 못하고 있음은 물론 해당업체에도 큰 혼란을 가져다주고 있다. 따라서 이 시점에서 짚고 넘어가야 할 문제는 무엇인지 대안은 없는지 생각해 보고자 한다.

  • The purpose of this paper is to explore the meaning of talent donations by semi-professional Athlete using Q methodology. This Q factor analysis finally identified 3 factors: The first factor, The type of donation cautious, They represent an understanding the need for donation, needing to prepare for donation, information about donation targets, careful attitude toward talent donation. The second factor, The type of donation authenticity, They represent departure from good mind, premise of authenticity to donation, necessity of program for donation activities. The final factor, The type of trust for endowment institution, They represent trust in the target organization to donate, interest in donation-related incidents, necessity of various donation methods in sports field.

  • Using data from the Household Income and Expenditure Survey over the period 1994-2016, we estimate the coefficient of relative prudence in order to capture precautionary saving motive. To do this, we adopt a cohort approach, where we transform such microdata into sample cohort means. Together with initial income involving liquidity constraint, we estimate the relative prudence derived from the Euler equation. The two-stage least-squares (2SLS) between estimate of it obtained from the cohort panel data analysis is too small for the existence of precautionary saving motive, as in previous studies, while the 2SLS random effects estimate is so reasonable. Moreover, the liquidity-constrained cohorts tend to be more sensitive to uncertainty, relative to the unconstrained ones.
