This study investigates the components and rating system of reliable technology credit information for a technology finance donor who is a consumer of the information and aims to create an effective and optimal technology credit appraisal system to enlarge technology finance supply. Firstly, we calculate the optimal TCAR which becomes the maximum AUROC through the combination of ratio change, verify the substitution possibility between TAR and CR through the existing CR and system gap simulation, and propose a rating system by which financial institutes can utilize the TCAR as a credit rating. As a result, 70% : 30% is the most suitable as the weighted combination ratio of credit rating : technology rating. As a result of this study, we confirmed the possibility that the technical credit rating information could be substituted by the credit rating or the technology appraisal rating. Furthermore, it also suggests that sophisticated risk management is possible through using technology credit rating that are combined with credit and technology appraisal rating.

The purpose of this study is to suggest the shortcomings and the direction of the web accessibility evaluation studies by analyzing the research trends on web accessibility evaluation in Korea. For this aim, a total of 59 theses presented in the registered academic journal and the candidate of registration academic journals from January 2000 to March 2017 were selected. The selected dissertations have been analyzed based on the evaluators, the evaluation targets, the evaluation methods, and the evaluation results with regard to web accessibility. As a result of the analysis, the highest rate in the evaluator aspect was 'independent evaluation (66 percent)' and the highest percentage in the evaluation target aspect was 'web site (83 percent)'. When it came to the evaluation methods, automatic evaluation and the mixture of automatic evaluation and manual evaluation had a similar percentage. Lastly, only two papers showed that web accessibility did not have any problems. This study is meaningful in the sense that it suggested a desirable direction for the web accessibility studies in Korea and web accessibility evaluation studies in the situation when the meta studies which analyzed research trends are insufficient.

This study focused on the use of student assessment activities to investigate the impact on reflective thinking in Argument-based Inquiry. The participants of the study were 166 10th grade students (six classes). Over one semester, students participated in five ABI programs that we developed. The experimental group (84 students) was taught Argument-Based Inquiry with students' self and peer assessment activities. The comparative group (82 students) was taught without the activities. We analyzed students' reflective writing to investigate how the student assessment activities influenced the students' reflective thinking. We also used the interviews and surveys to examine the validity of student assessment activities. According to analysis of the reflective writing, the experimental group had a significantly higher mean score than the comparative group in the 3rd and 5th writing. The ratio of students who showed a metacognitive level of reflection with regard to analysis of inquiry process, understanding of learning, and change of thinking increased in both groups, but the experimental group's ratio was higher than the comparative group's. The result of analysis of the reflective practice showed that the ratio of the experimental group's students who reached the metacognitive level of reflection in their writing increased, while the comparative group's decreased. Therefore, we conclude that student assessment activities can create a learning environment that facilitates student participation, increases the students' engagement in the learning process, and can be used as a tool to scaffold learning.

This paper investigate the determinants of investment for a cross-section of firms in emerging market. I examine three factors expected to affect investment: debt ratio, growth rate, and industry. I find that debt ratio and ICT firms are positively associated with investment in emerging market. I also find that ICT firms with high debt ratio have higher net capital expenditures. While the growth rate is unrelated to net capital expenditures. Unlike the evidence from the developed markets, debt ratio has significant and positive impact on investment (net capital expenditures) in the emerging market.

우리 나라 경제는 1993년 이후로 호황을 유지하다가 1996년 말부터는 경제불황이 닥쳐, 현재는 구제금융이라는 최악의 경제혼란기에 처해 있다. 하루에도 기업의 도산은 부지기수로 발생되고 있으며, 도산으로 인하여 국민들은 직장을 싫고 물가인상 등으로 가계마저 흔들리고 있는 실정이다. 이러한 이유로 본 연구에서는 재무비율에 의한 기업도산예측모델을 설정하려고 한다. 연구의 자료는 1996년 3월 은행연합회에서 개발한 '기업신용평가표'에 나타난 재무비율을 이용하였다. 연구의 결과를 보면 '기업신용평가표'의 변수는 기존연구에 비교하여 보면 도산예측력이 낮은 편인데, 그 이유는 기존연구는 대부분 통계적으로 검증된 5-6개의 변수를 대상으로 도산예측력을 나타내고 있는데 반하여, 본 연구에서는 기업신용평가표에서 선정된 모든 변수를 대상으로 분석했기 때문이다. 그러나 대체적으로 분석하여 볼 때 기업신용평가표의 재무비율 선정은 양호한 편으로 생각된다. 그러나 본 연구의 주목적은 신용평점에 의한 도산예측력분석이므로 본 연구의 선정모형에서 나타난 자기자본비율, 현금흐름/총부채(고정장기적합율), 매출액경상이익율, 총자본순이익율, 영업자산회전율 등은 기업신용평가내지 도산예측분석에 유용한 것으로 나타났다.

The interval estimation for binomial proportion has been treated practically as well as theoretically for a long time. In this paper we compared the properties of major confidence intervals and summarized current issues for coverage probability and interval length which are the criteria of evaluation for confidence interval. Additionally, we examined the three topics which were considered in using the binomial confidence interval in the field. And finally we discussed the future studies for a low binomial proportion.

This study was performed to develop and evaluate functional prepared with optimum mixing of mulberry leaf and fruit powder using response surface method (RSM). In order to develop the optimized functional Nokdujukr using RSM, mulberry leaf powder (MLP:X1) and mulberry fruit powder (MLF:X2) were set as independent variables, and pH (Y1), sweetness (Y2), viscosity (Y3), L (Y4), a (Y5), b (Y6), color (Y7), flavor (Y8), taste (Y9), overall quality (Y10), TPC (Y11), and DPPH radical scavenging ability ($IC_{50}$)(Y12) were set as dependent variables. The optimum mixing ratio of MLP and MLF was determined to be 3.88 g of MLP and 6 g of MLF. The values of color, flavor, taste, overall quality, TPC, and DPPH radical scavenging ability ($IC_{50}$) of optimized Nokdujuk were 5.20, 5.85, 6.00, 6.22, 330.99 mg TAE/g and 650.10 g/mL, respectively. In conclusion, this study has led to the development of an improved version of Nokdujuk that has antioxidative properties and good sensory evaluation and, will likely serve as a functional meal replacement for the busy modern world.

본 논문에서는 한국어 입력 텍스트의 의미를 반영하는 색상 팔레트를 생성하는 방법을 제안한다. 기존 영문 모델에서 한국어의 특수성을 고려하여 입력 방법과 형태소 분석, 임베딩 등 여러 조건을 달리한 접근을 시도하고 최종적으로 두개의 모델을 선정하여 평가를 진행한다. 정량적 평가인 단일 팔레트 다양성 평가와 정성적 평가인 사용자 평가를 진행하였으며 결과 기존 영문 버전보다 다양성이 높았고 사용자가 실제 팔레트 보다 생성된 팔레트를 선호하는 비율도 향상되었다. 이번 연구로 한국어 임베딩을 활용하여 팔레트를 생성하였을 때 보다 다양한 색상과 의미적으로도 적합한 색상을 선정함을 확인할 수 있었다.
