2015 개정 교육과정에서 컴퓨팅 사고력의 함양을 강조하고 있지만 컴퓨팅 사고력을 평가하기 위한 도구에 대한 개발이 미흡하다. 비버 챌린지 문항은 전 세계 60여개국의 정보 교육 전문가 집단이 약 1년 동안 공동 출제 및 검토를 통해 개발되는 문항이므로 문항의 타당도가 높다고 볼 수 있다. 다만 초기의 개발 목적이 평가도구로써 사용하기 위함이 아니었기 때문에 과연 컴퓨팅 사고력의 평가 도구로 사용할 수 있는 신뢰도를 가진 문항인가를 검증하기 위해 본 연구에서는 비버 챌린지 2017 그룹 III의 문항을 대상으로 문항내 적일관성신뢰도를 통계적으로 검증하였으며 그 결과 Cronbach ${\alpha}=.784$로 신뢰도가 높게 나타났다.

본 연구에서는 컴퓨팅 사고력 평가도구로써 비버 챌린지 문항을 활용하기 위하여 문항반응이론을 통해 비버 챌린지 문항을 분석하고, 비버 챌린지에서 기존에 제시하는 난이도와 문항반응이론을 통한 난이도 간의 상관관계를 분석하였다. 분석 결과 비버 챌린지는 쉽고 변별력이 높은 검사로 나타났으나, 비버 챌린지에서 제시하는 난이도와 문항반응이론을 통한 난이도 간의 상관관계는 없었다. 난이도에 따라 가점과 감점이 이루어지는 비버 챌린지 채점 기준을 고려할 때 정확한 컴퓨팅 사고력 측정을 위해서는 난이도에 대한 수정 및 보완이 필요하다.

본 연구에서는 컴퓨팅 사고력 평가 도구 중 자기보고식 설문과 지필형 검사지인 비버 챌린지 간의 상관관계를 분석하고자 하였다. 두 평가 도구를 사용한 결과 간의 상관관계는 통계적으로 유의하지 않았다. 따라서 객관적인 측정을 위하여 자기보고식 설문에 대한 수정 및 보완이 필요하며, 비버 챌린지의 점수에 영향을 주는 난이도에 대한 고찰이 필요하다. 덧붙여 산출물 평가와 자기보고식 설문, 지필형 검사지 간의 상관관계를 분석할 필요가 있다.

The founding of ching costume system starts from the rule issued in second year of Te-chong reign that the clothing of Manchu people is prohibited to be chinesized. It has undergone many revisions and is officially established in the 37th year of Chien-lung reign. This study is Emperor's costumes during the year in Chien-lung reign. The results are as follows: Emperor's costumes go to the travel are Chi-fu hat and Hsing-fu. Sea-dragon hat changes on otter skin or beaver hat and Ching-rong and ching-ni hat changes velvet hat. Light green informal wear is to be worn once a year. Name of sacrificial robes does not exist in Ching-hui-dien-tu but it take the place of Chao-fu I and Chao-dai II in Chuan-dai-dang-an. Sacrificial robes wear with indigo boots and the other cases wear blue boots and shoes and socks. The shape on ornaments in belt of sacrificial robes is tetragon style.

The present paper addresses magnetohydrodynamic pulsating flow and heat transfer of two immiscible, incompressible, and conducting couple stress fluids between two permeable beds. The flow between the permeable beds is assumed to be governed by Stokes' [28] couple stress fluid flow equations, whereas the dynamics of permeable beds is determined by Darcy's law. In this study, matching conditions were used at the fluid-fluid interface, whereas the B-J slip boundary condition was employed at the fluid-porous interface. The governing equations were solved analytically, and the expressions for velocity, temperature, mass flux, skin friction, and rate of heat transfer were obtained. The analytical expressions were numerically evaluated, and the results are presented through graphs and tables.

Various theoretical models have developed io both a family research area and family therapy field on he basis of several family theories and social theories in order to understand the family life and its function. These theoretical models have give rise to provide not only a framework for family therapy bt also opportunities for the development of family studies. Regardless of the devotion of these theoretical models to a family therapy however some family therapy professions have suggested the disvergence between these models and practice because the models tend to confuse therapists in their actual practices Other family therapists on the other hand have claimed the convergence between these models and practice. One of the reasons for the issues of convergence and disvergence in the family therapy study would be that various theoretical models have different sometimes contradicatable definitions and explanations for same concept. Therefore the purpose of this paper is to investigate the extent of similarities and differences among these theoretical models of practice in a way of examining family models to compare Olson's circumplex model to the Beavers systems model. Both models were based on the general systems theory. This paper consists of the explanation of Olson's circumplex model and Beavers systems model in general respectively. Then it will investigate similarities and differences between these two models in terms of the relationship between family functioning and family adaptability.

A automatic flight control system(AFCS) of UAS needs to control its flight path along target path exactly as adjusts flight coefficient itself depending on static or dynamic changes of airplane's features such as type, size or weight. In this paper, we propose system which tunes control gain autonomously depending on change of airplane's feature in flight as adding MLM(Machine Learning Module) on AFCS. MLM is designed with Linear Regression algorithm and Reinforcement Learning and it includes EvM(Evaluation Module) which evaluates learned control gain from MLM and verified system. This system is tested on beaver FDC simulator and we present its analysed result.

This study investigates and analyzes the difference in Indonesian banks' earnings quality in the pre-audit and post-audit period. This study also investigates the difference in audit quality done by public accounting firms. This study employs time series data taken from the unaudited and audited financial statements of banks listed on the Indonesia Stock Exchange in 2012-2016. Sample selection is made by using a purposive sampling method. The population of this study is 43 banks, and after checking the data for validity and reliability, the final sample size was 26 banks. Audit quality is operationalized with the size of the auditor. Earnings quality is proxied by accruals calculated using the Beaver and Engel (1996) model. The data analysis method used in this study is the paired-sample t-test and chow test. This study shows that there is no difference in earnings quality in the pre-audit and post-audit period. This study also reveals no difference in audit quality between the big four and non-big four auditors. These findings mean that independent auditors do not play a useful role in increasing the reliability of accounting information presented by management to stakeholders. Besides, this study's results do not verify the agency theory regarding auditors' role to minimize opportunistic management behavior in preparing financial statements.

In the 2015 revised curriculum, software (SW) education was strengthened to cultivate computational thinking. In the curriculum of practical course at elementary school and of informatics course at secondary school, the characteristics, and content systems of SW education have developed systematically. However, it is necessary to study practical methods and cases for SW education because the curriculums provide only note and direction about teaching & learning, and evaluation methods for SW education. The purpose of this study is to analyze the achievement standards of the SW curriculum in the tasks of Bebras Challenge 2017 and to suggest various methods of teaching and learning, and of evaluation using the Bebras tasks. The results of this study are expected to propose a basis to develop various teaching and learning and evaluation researches.

As the importance of SW education grows, researches are actively being conducted to improve students' thinking skills. We conducted the group III tasks, which are experiencing and challenging in Beaver Challenge 2018, on 55 students of 5th grade in elementary school. Based on the result, we analyzed their average scores and defined whether each test has a correlation with possession of smartphone, computer familiarity, patience, concentration, and academic ability. The result indicated challenging task boosted the average score, the percentage of correct answers, and the percentage of correct answers for each level of difficulty. Moreover, the challenge task scores were higher as they higher computer familiarity, patience and concentration level. However, possession of smartphones and academic ability did not affect the score. Lastly, the scores were affected by different factors in different level of difficulty that patience factor in advanced level, computer familiarity factor in intermediate level, and concentration factor in beginner level. Thus, further researches are necessary to be conducted to expand the scope of the analysis through the diversification of test subject group and expansion of an evaluation area.
