  • 21세기는 수학적 사고 신장뿐만 아니라 수학에 대한 긍정적인 가치 인식이 형성되도록 수학교육이 이루어져야 하지만 교육현장에서는 정의적 영역의 중요성이 간과 되어왔다. 따라서 본 연구는 다양한 방법과 전략을 사용하여 여러 가지 정답을 산출할 수 있는 개방형 문제를 이용한 학습에 대해 아동이 어떠한 태도를 보이는지 연구하였다. 개방형 학습에 대한 아동들의 태도를 관찰과 면담, 설문조사를 통해 분석한 결과 아동들은 수학에 대한 흥미와 자신감이 생기고 성취감을 느껴 수업에 집중하였다. 또한 토의학습을 통해 서로 상대방의 능력을 존중하는 태도를 형성하며 교과서 문제를 변형시킨 개방형 문제에 자신 있게 반응하고 수학을 바라보는 태도에서 발전적인 모습을 보였다. 본 연구 결과 수학에 대한 긍정적이 태도를 형성하기 위해서는 교과서 문제를 개방형 문제로 변형시켜 현장에 적용하려는 노력이 필요하다.

  • In this paper, we propose a fast interest point detection method using SURF algorithm. Since the SURF algorithm needs a great computations to detect the interest points and obtain the corresponding descriptors, it is not suitable for real-time based applications. In order to overcome this problem, the interest point detection step is parallelized by OpenMP and SIMD based on analysis of the scale space representation process and localization one in the step. The simulation results demonstrate that processing speed is enhanced about 55% by applying the proposed method.

  • The purpose of the study was to investigate jean consumption among middle-aged Korean women and the characteristics of consumers as potential jean consumers. The data were collected from the survey of 238 Korean women aged 45 to 64 years old. The respondents prefer outlet store to other retail outlets and wear jeans mainly for travel, grocery shopping, and outing. The main reason for not wearing jeans is body change, which leads to poor fit in abdomen and waist area. The sample was clustered into two groups based on interest in jeans: high-interest and low-interest group. From the examination of group differences, the high-interest group rated conformity/brand reputation, scarcity, and attractiveness of appearance significantly higher compared to the low-interest group among the five clothing benefits pursued. No difference was found in obesity and body satisfaction. Group differences were found in recent purchase, price, number of jeans owned, and frequency of wearing jeans. The results suggest the characteristics of the potential jean market among middle-aged women in Korea. Implications are discussed.

  • 본 논문에서는 차량 헤드라이트의 불량 유무를 판별하기 위하여 생산된 헤드라이트 이미지를 위치 및 회전 보정 후 검사이미지의 ROI(Region of Interest)와 표준 이미지의 ROI와의 유사도를 이용하여 불량 유무를 판단하는 방법을 제안하였다. 유사도 판별은 OpenCV에서 제공하는 템플릿매칭 유사도 판별방법을 응용하여 히스토그램 기반에서 유사도를 판별하는 방법을 사용하였고, 성능 분석을 목적으로 기존 OpenCV의 기본 방법과 비교하였다. 분석결과, OpenCV의 기본 방법보다 좋은 성능을 보임을 알 수 있었고, 제안 방법의 경우 불량 판별율 100%에 근접함을 알 수 있었다.

  • Objective: The goal of this study is to research how mother's literacy interaction influences children's interest in vocabulary and reading. Methods: The research subjects selected were 120 children who were three to four-year-old and their mothers. This study conducted questionnaires about the literacy interaction of the mothers. This study also surveyed vocabulary and interest in reading of the children by directly visiting the institutes and by researching the subjects individually. This study used technical statistics, Person's product-moment correlation analysis, and multiple regression analysis in order to analyze the collected data. Results: The results of this study are summarized and concluded as follows. First, open interaction among the sub-areas of a mother's literacy interaction significantly affected children's vocabulary. Second, a mother's literacy interaction with children had no direct impact on the child's interest in reading. Conclusion/Implications: The mother's literacy interaction could have a correlation with the vocabulary development of three to four-year-old children, and a mother's application of open interaction could significantly influence the receptive vocabulary and expressive vocabulary of children.

  • This study uses the benchmark interest rate of the Federal Open Market Committee (FOMC) to predict gold futures prices. For the predictions, we used the support vector machine (SVM) (a machine-learning model) and the long short-term memory (LSTM) deep-learning model. We found that the LSTM method is more accurate than the SVM method. Moreover, we applied the Boruta algorithm to demonstrate that the FOMC benchmark interest rates correlate with gold futures.

  • ^x Open space has become the subject o\ulcorner remarkable, new interest ; and many studies have been done recently. In urban pattern, the significance of open space is not its quantity but how it is arranged. The end of this article is to set up a plan for the open space system for Kyongiu city. This paper has three parts : first, a brief discussion of the concept and function of open space ; secondly, a review of open space system ; and finally, a case study of Kyongju City. Especially, this study is focuced on the methodology in conserving and using prototype plan for historic and cultural environment. The result of this study may be summed up as follows : 1) The open space network for kyongju city can be planned out as a belt and ripple pattern. 2) The linear element of open space must play an important role in connecting each element with the whole open space system. 3 ) The Hwangseong pork can be the focal element of the open space system.
