This study analyzes the relationship between OECD DAC aid and recipients' corruption based on the good governance discussion. The study applies a fixed-effect model and PCSE model with a dataset of 43 African countries' corruption perception index, World Bank data, Polity IV, and OECD DAC aid statistics between 2000 and 2014. A statistical analysis confirmed that OECD DAC aid has a negative impact on corruption in African countries. DAC's aid affects negatively to corruption in African countries, especially in countries where democracy has matured. This research suggests that a more comprehensive follow-up study of the OECD DAC's good governance-oriented aid. Simultaneously, the general democratic effect on the recipients' institutions could not be applied in African countries, when considering regional peculiarities.

Software education is drawing attention as an education for fostering future talents who will lead the 4th industrial revolution. The purpose of software education for everyone from kinder to adults is not simply to develop programming skills, but to develop "Computational Thinking," a problem-solving ability that effectively solves real-world problems based on computing. Therefore, how to cultivate and evaluate computational thinking is a very important issue. This paper proposed a method of applying a process-based performance evaluation method to evaluate computational thinking ability in the process of solving learners' problems. The developed contents were revised and supplemented through two Delphi surveys by a group of experts consisting of five university professors and five incumbent information teachers majoring in computer science and computer education to verify the effectiveness of the final model. I hope This paper can contribute to the study of evaluating computer thinking ability from the perspective of problem solving.
