The purpose of Environmental subject in the Korean school is pretty much similar to that of international organization. Because it doesn't apply the characteristics of School Education to environmental education, this school environmental education purpose needs to be discussed. The purpose of this study is to establish the reasonable purpose of school environmental education by analyzing the educational views. This study have been done through review of research literature, which usually includes references and papers on environmental education, school environmental education, educational point of view, educational purpose. It analyzed three kinds of views on education: technological view on education, initiation view on education, socialization view on education. The results are as follows: The purpose of school environmental education from technological view on education is environmental education activity itself that educates students to put the environmental preservation value into action. Initiation view on education aims at school environmental education as activities that instruct students on intellectual ability in order to develop a comprehensive view of intelligence. The purpose of environmental education in school on the basis of socialization view on education focuses on activities that authoritative teachers transmit the social value of environmental preservation to students in school.

The research purpose of this paper is to empirically examine the effects of technological readiness and innovation on logistics performance. To build up and maintain an important role in global supply chains, nowadays it is obvious that countries and logistics providers need to achieve competitive advantage in terms of digitalization. However, there is a lack of empirical studies about the impacts of information technologies and innovation potential on the logistics efficiency of countries. Hence, the study analyzes whether the corresponding pillars of the Global Competitiveness Index (GCI) matter for the Logistics Performance Index (LPI) and its dimensions. For determining the effects, the pooled regression approach is applied. The results show that technological readiness and innovation are positively and statistically significantly correlated with logistics performance: competence and quality of logistics services, efficiency of customs clearance processes, ability to track and trace consignments, frequency with which shipments reach consignee within scheduled or expected time, and ease of arranging competitively priced shipments. The findings of this study suggest that investments in innovations and technology progress improve countries' logistics efficiency, which is an important prerequisite for enabling Logistics 4.0 and thus, Industry 4.0 and the digital transformation of the economy and society.

Our present ability to work with video has not been confined to wired communication environment. This paper describes the new technological trend of wireless video communication. In wireless video communication, unlike wired network, several techniques are needed. At first, error robust video coding is essential. Due to characteristics of wireless channel, the system is exposed to more error prone environment. In addition, encoded video bit streams are vulnerable to the error because of the entropy coding. Recently many frameworks are developed to cope with this problem. We just explore the numerous robust video coding approaches with the viewing of error control. And more we discuss other on going research topics in this wireless video communication fields like low-power assumption design, trans-codec technique, and rate control schemes in brief.

The purpose of the study is to examine how effects of activities using Google SketchUp on students' spatial ability and 3D geometric thinking in measuring the volume of solid figures. By comparing the results from pre- and post-tests between the experimental group and control group, we found that activities using Google SketchUp help students improve their spatial ability in the spatial orientation and visualization. In addition, more than half students in the experimental group moved from level 4 up to level 7 in thinking process of measuring the volume in terms of Battista(2004)'s levels. This study suggests that the instruction with Google SketchUp can help to improve students' spatial ability and 3D geometric thinking in the regular class in middle school. In addition, SketchUp can be an advanced technological tool to support students' self-directed learning, which create an efficient educational environment and a great opportunity to learn geometry in an effective manner.

Mistletoe (Viscum album) lectins, which are classified as a type II ribosome-inactivating protein (RIP) due to their unique biological function and the potential medical and therapeutic application in cancer cells, receive a rising attention. The heterodimeric glycoproteins contain the A-chain with catalytic activity and the B-chain with sugar binding properties. In recent years, studies involving the lectins from the white berry European mistletoe (Viscum album) and the yellow berry Korean mistletoe (Viscum album coloratum) have been described. However, the detailed mechanism in exerting unique cytotoxic effect on cancer cells still remains unclear. Here, we aim to understand and define the molecular basis and biological effects of the type II RIPs, through the studies of the recombinant Korean mistletoe lectin. To this end, we expressed, purified the recombinant Korean mistletoe lectin (rKML), and investigated its molecular characteristics in vitro, its cytotoxicity and ability to induce apoptotic cell death in cancer cells. To gain structural basis for its catalytic activity and sugar binding properties, we performed homology modeling studies based on the high degree of sequence identity and conserved secondary structure prediction between Korean and European, Himalayan mistletoe lectins, and Ricin.

한국 디지털사회의 형성과 발전에는 역사적으로 기술의 굴절적 토착화와 과열된 기술숭배가 자리한다. 역사적으로도 인터넷에서 '신'권위주의적 통제와 억압의 계기적 측면이 과도하게 집중화되고 있는 반면 아래로부터 이용자들의 적극적 시민적 의제 형성을 위한 자율의 움직임은 다른 어느 나라보다 정치적이다. 이 글은 적어도 1990년대 이래 이와 같은 한국의 디지털 기술의 전개 방식에 있어서 국가적 특수성을 보려 한다. 이 글에서 '기술잉여'는 한 사회의 통제 능력 이상으로 과도하게 기술들이 비정상적으로 사회에 착근되는 상황을 지칭한다. '기술잉여사회'란 바로 이와 같은 기술잉여가 누적적으로 나타난 특징적 사회 유형을 지칭한다. 이는 제도정치의 성숙도에 비해 기술과잉과 잉여에 의해 빚어지는 사회 왜곡과 비정상성이 잦은 우리 사회를 상징화한다. 이 글에서는 기술잉여사회의 특성을 유형화하고, 중국, 일본, 미국 등 정보기술 영향력의 경쟁 국가들과의 비교를 통해 한국적 기술발전의 퇴행성을 구체화한다.

벤처기업의 기술혁신을 위한 기술력 평가는 급변하는 기업환경, 평가시 사용하는 언어의 모호성과 애매성, 평가지표의 부정확성을 고려해야 한다. 본 논문에서는 벤처기업의 대표적인 정성적 평가요인인 흡수역량 및 기술적 기업가정신을 대상으로 다기준 의사결정법인 Fuzzy-AHP를 적용하여 요인의 중요도와 우선순위 및 동적역량을 산출하는 ACTEM(Absorption Capacity and Technology Entrepreneurship Monitor) 모델을 제안하였다. 평가척도가 되는 요인에 대한 가중치 산출은 퍼지이론을 도입하여 인지적 판단의 애매성을 보완하고, 기존의 기술력 평가 측정에 관한 연구에서 고려하지 않은 흡수역량과 기술적 기업가정신 및 동적역량에 대한 평가 기준들을 제시함으로써, 현실적인 대안을 선택하는 것이 가능하도록 하였다. ACTEM 모델을 기존의 AHP 평가방법과 비교한 결과, 흡수역량에서는 '지식획득', 기술적 기업가 정신에서는 '제품화 능력'이 가장 높게 나오는 등의 타당성을 검증할 수 있었다.
