There is a problem with the existing method of selecting the difficulty levels of Hanja characters. Some Hanja characters selected by the existing methods are different from Sino-Korean words used in real life and it is impossible to know how many times the Hanja characters are used. To solve this problem, we measure the difficulty of Hanja characters using the multiple regression analysis with the frequency as the features. Based on the elementary textbooks, FWS and FHU are counted. A questionnaire is written using the two frequencies and stroke together to answer the appropriate timing of learning the Hanja characters and use them as target variables for regression. Use stepwise regression to select the appropriate features and perform multiple linear regression. The R² score of the model was 0.1105 and the RMSE was 0.1105.

In this paper, I developed a assesment indicator to evaluate SW program developed by students in SW education. The SW education carry out in elementary school, middle school and high school from 2016. But the assesment indicator to evaluate SW program had not been developed until now. Therefore, I tried to develop the assesment indicator that have harmoniously educational characteristic and SW qualitative characteristic. First of all, I had set the 15 attributes for assesment and developed the 36 criteria for 15 attributes. And the validity of 15 attributes and 36 criteria for assesment had been reviewed by 39 SW educational experts. As a result, the 15 attributes and 36 criteria for assesment were determined to which that have validity. I expect that the assesment indicator developed in this paper will raise the reliability of evaluation in SW education. And the assesment indicator may be used at SW competition conference for teenagers.

80년대초 이후 기술혁신의 가속으로 중소기업에서도 기술변화에 대한 적응이 경쟁력의 유지를 위한 핵심과제가 되면서, OECD 국가는 중소기업에 대한 과학기술정보(科學技術情報)의 이전(移轉)을 촉진하는 정부지원을 확충하였다. 경제성과의 개선을 위해서는 기술혁신만이 아니라 기술혁신의 성과를 확산시키는 것도 중요하다는 인식으로 중소기업의 경쟁력향상에 기여하는 과학기술정보의 공급확대를 위하여 연구개발사업(硏究開發事業)에 대한 지원을 강화하는 동시에 중소기업에 대한 과학기술정보의 이전을 촉진하기 위하여 과학기술정보의 공급원(供給源)(대학, 시험연구기관 등)과 중소기업을 연결하는 다양한 중개(仲介)(촉매(觸媒))기관(機關)의 설립 운영을 지원하고 있다. 연구개발과 과학기술정보이전에 관한 과학기술공급원과 중소기업간의 인식의 차이를 해소하기 위하여 정보교환(情報交換)과 인적교류(人的交流)를 확대하고 과학기술공급원이 제공하는 지식을 중소기업이 이용하기 쉬운 기술로 변환하기도 한다. 이러한 기능을 중개기관이 효과적으로 수행하기 위해서는 중소기업 사업자와 신뢰관계(信賴關係)를 구축하는 것이 긴요하며, 기술변화를 인지 수용하도록 유도하는 초기단계에서는 중소기업의 네트워크를 통하여 접근하는 것이 효과적이다. 이러한 기술확산과정(技術擴散過程)의 특성으로 인하여 지역혁신체제(地域革新體制)의 구축과 기술혁신정책(技術革新政策)의 지역화(地域化)가 강조되고 있다. 최근에 통상산업부와 과학기술처도 기술혁신정책의 지역화를 시도하고 있다. 연구기반과 산업기반을 고려하여 지역별로 다양한 유형의 산학연 공동연구기반이 구축될 계획이다. 기술혁신정책의 지역화는 시도단계에 불과하며 효율적인 지역혁신체제를 구축하기 위한 여건도 불리하다. 선진국에 비하여 대학과 연구기관의 연구자원(硏究資源)에서도 현격한 차이가 있으나, 네트워크의 혁신성을 좌우하는 지식집약형 중소기업의 비중과 중소기업기술개발의 혁신성에서도 선진국에 비하여 절대열위에 있다. 이러한 불리한 여건을 극복하기 위하여 중소기업의 혁신현장에 밀착된 지역의 전문가집단이 지역경제의 비전과 지역산업의 특수성을 고려하여 지역연구개발사업(地域硏究開發事業)을 전략적으로 기획하고 효율적으로 추진하며, 기획 추진과정에 참여하는 지역대학 지역시험연구기관 지역산업단체 등이 구성하는 지역사회(地域社會)의 협의체(協議體)가 정보공유(情報共有)와 공동학습(共同學習)을 통하여 지역혁신체제의 형성을 주도하고 경쟁과 협력의 조화를 통하여 기술혁신을 가속시키는 지역사회(地域社會)의 규범(規範)과 문화(文化)가 정착되도록 노력하며 중앙정부는 지역연구개발사업에 대한 지원에서 투명하고 합리적인 평가기준을 제시하고 지역산업의 혁신성과에 의하여 지원을 차등화(差等化)하는 경쟁원리를 도입하여 지역사회의 합리적 의사결정을 유도해야 한다.

The purposes of this study were to analyze the contents of sulfuric acid in Science textbooks and Chemistry II textbooks, and to survey 10 pre-service teachers' perceptions who majored chemistry education related to sulfuric acid. As results, most of the Science textbooks represented that sulfuric acid was divided into two $H^+$ and one $SO_4{^{2-}}$. But this mistake might be corrected because sulfuric acid was divided into one $H^+$and one $HSO_4{^-}$. Most of Chemistry II textbooks represented ionization steps of sulfuric acid, but same mistake was represented in some of Chemistry II textbooks. $HSO_4{^-}$ is a weak acid, but some Chemistry II textbooks represented $HSO_4{^-}$ as a strong acid. As results of the survey related to pre-service teachers' perceptions, some pre-service teachers didn't know the situation of particles in sulfuric acid solution, and they were affected on by the learning of high school classrooms.
