In recent years, 'technological fusion or convergence' has drawn a lot of attention of innovation researchers and governmental policy makers as the driving force of technological innovation and industrial growth. There are, however, few studies on the analysis of longitudinal trends of technological convergence and its comparison between global and national level. In this study, with the citation data of about 18 million articles, we analyzed 1) the growth of representative convergence research areas, 2) the convergence of citing patterns between research fields, and 3) the changing trend of diversity index of all research fields. We conclude that technological convergence in korea shows the relatively strong orientation to the combination of neighboring fields than that of heterogenous fields in comparison to global trend. In particular, the relatively weak activity of cognitive science and the low level of mutual exchange between arts/humanities/social sciences and natural/engineering sciences in Korea are emphasized.

It is difficult to find an appropriate ordering policy for a many types of items. One of the reasons for this difficulty is that each item has a different demand trend. We will classify items by shipment trend and then decide the ordering policy for each item category. In this study, we indicate that categorizing items from their statistical characteristics leads to an ordering policy suitable for that category. We analyze the ordering policy and shipment trend and propose a new method for selecting the ordering policy which is based on finding the strongest relation between the classification of the items and the ordering policy. In our numerical experiment, from actual shipment data of about 5,000 items over the past year, we calculated many statistics that represent the trend of each item. Next, we applied the canonical correlation analysis between the evaluations of ordering policies and the various statistics. Furthermore, we applied the cluster analysis on the statistics concerning the performance of ordering policies. Finally, we separate items into several categories and show that the appropriate ordering policies are different for each category.

Records of industrial accidents are essential to maintain efficient and successful safety programs. The objective of this study is to examine the trends of industrial accidents in manufacturing industry, based on the national statistics. From 1972 to 1994, statistics of industrial accidents were extracted from the annual publications of Ministry of Labor. The results show that there are significant characteristics and trends in the records of industrial accidents. These findings identified in this study can be used to manage the accident prevention efforts.

Recycling involves processing used materials into new products and remanufacturing is an industrial process in which worn-out products are restored to like-new condition. Recycling and remanufacturing industry is environmentally and economically important industry and provides significant benefits to prevent waste of potentially useful materials and reduce energy usage. The purpose of this research is to investigate the trend of recycling and remanufacturing industry in Korea and other countries like Germany, Japan and America. The yield information is generally quite valuable to promote green growth industry as an important alternative in the 21st century.

Chinese government has implemented the West Development Strategy since 1999 to boost the region's growth and prevent the environmental degradation. Until now, the regional economy and living standard in Western China have been greatly improved, while it also indicated by the State Council that the ecological environment still deteriorated with part improvement, and pressure of water shortage increased. The paper focus on the relationship of GDP per capita and the volume of industrial waste water discharge of all the 12 provinces in Western China from 1989 to 2004, by the expanded EKC model in the cubic form. Results show that they mainly have down trend in the whole sample space but small up trend in the recent years. That means controlling of industrial wastewater discharge is still an important task to be insisted in the Western China.

Recently, mobile-phone with camera module has an absolute majority in the released mobile-phones. For this trend, High precision of the plastic subminiature barrel which is the core part is needed significantly because the camera module of mobile-phone must have high performance. Therefore, Structural stability of the injection mold for plastic subminiature barrel has to be guaranteed. In this paper, structural analysis of injection mold for plastic subminiature barrel is performed. Finally, the deformation trend and stability of injection mold core are analyzed.

기존의 부상기술 예측은 주로 정성적으로 이루어졌으나, 이는 많은 비용이 요구된다. 이에 대안으로 개발된 기술의 다양한 정보를 포함하는 특허를 활용한 정량적 방법이 있다. 기존에 특허 출원 건수를 이용한 정량적 예측 방법은 적은 출원이 이루어지는 부상기술 특허를 파악하는데 어려움이 존재한다. 이를 해결하기 위해, 선행연구에서는 추세선의 기울기를 사용하여 부상기술을 예측하였다. 그러나 출원 건수가 많은 핵심기술의 기울기가 크게 도출되므로 여전히 부상기술 파악에 어려움이 존재한다. 본 논문에서는 기술들의 Patent Power를 이용하여 상기 문제를 해결하며, 연도별 Patent Power의 변화를 이용하여 기울기를 구하고 부상기술을 예측한다. 또한, 최다 출원인을 확인하고 경영전략을 제시한다. 실험으로는 AR 분야의 특허 중 USPTO에 공개된 특허만을 사용하며, 부상기술로는 G02B가 도출되었다.

In the era of the Fourth Industrial Revolution, digital transformation, which means changes in all industrial structures, politics, economics and society as well as IT technology, is an important issue. It is difficult to know which research topic is being studied because digital transformation is being studied in various fields. Convergence research is possible because a research topic is studied in various fields such as computer science area and Decision science area. However, it is difficult to know the specific research status of the research topic. In this study, eight research topics were derived using the topic modeling technique of text mining for abstract of academic literature and the trend of each topic was analyzed. We also proposed to create a Topic-Word Proportions Table in the LDA based Topic modeling process to predict the topic of new literature. The results of this study are expected to contribute to advanced convergence research on topic of digital transformation. It is expected that the literature related to each research topic will be grasped and contribute to the design of a new convergence research.

산업계 수요에 따른 중국 공학교육의 주요 개혁 동향들을 고찰하였다. 중국 공학교육 개혁의 추진 배경은 소련식의 전문교육과 문화대혁명의 영향으로 산업계의 고급 기술자가 부족하고 연령상의 단절이 있으며 졸업생들의 현장 적응력이 부족했기 때문이었다. 이에 따라 80년대부터 다양한 경로를 통해 산업계 수요에 맞는 신규 인력의 공급을 확대하고 기존의 산업계 기술자를 재교육하기 시작하였다. 이공계 대학의 입학 정원이 크게 증가하였고 대학원 입시에서 실무 경험자를 우대하는 정책을 실시하였다. 국가 교육위원회 주도로 산업계 수요에 맞는 고급 기술자의 양성 경로를 탐색하고, 이를 토대로 산학 협동의 공정석사 양성 방안을 실험하였다. 공과대학의 주요 개혁 동향으로는 우수학생의 양성, 복수 학위 제도, 현장 실습 강화, 학. 석사 통합 운영, 논문 석. 박사 제도, 산학 협동 인력 양성, 실험 대학, 성인 대학, 지방분교의 운영 등이 있다. 21세기를 앞두고 이러한 개혁 동향이 더욱 가속될 것이다.

본 논문은 2000년대 한국의 16개 시도의 기업가정신 추이를 분석하고 지역별 기업가정신의 결정요인을 분석했다. 최근 2008년의 기업가정신은 광역시를 중심으로 과거보다 크게 위축된 것으로 나타났다. 또한 기업가정신의 결정요인 분석을 통해 연구개발투자, 재산권 보호, 산업집중도, 지방정부 재정지출의 GDP 대비 규모가 기업가정신의 주요한 결정요인임을 확인했다. 연구개발투자 및 재산권 보호의 확대는 기업가정신을 촉진하고 지방정부 규모의 확대는 기업가정신을 저해하는 것으로 나타났다. 산업집중도의 경우 전체 기업가정신에 미치는 영향은 통계적으로 유의하지 않지만, 특정지역의 산업구조가 특정 산업에 편중될수록 개인사업체의 기업가정신은 위축되는 반면 회사법인사업체의 기업가정신은 확대되는 것으로 분석됐다.
