Automatic welding has been used frequently on pipeline projects. The productivity and reliability are most essential features of the automatic welding system. The mechanized GMAW process is the most widely used welding process and the carriage and band system is most effective welding system for pipeline laying. This application-oriented paper introduces new automatic welding equipment for pipeline construction. It is based on cutting-edge design and practical welding physics to minimize downtime. This paper also describes the control system which was designed and implemented for new automatic welding equipment. The system has the self diagnostic function which facilitates maintenance and repairs, and also has the network function via which the welding task data can be transmitted and the welding process data can be monitored. The laser vision sensor was designed for narrow welding groove in order to implement higher accuracy of seam tracking and fully automatic operation.

This paper presents the results of an empirical study on the relationship between the type of new product idea sources and the rate of success of new product development and commercialization in Korean industries. The sample was taken from various Korean industries including telecommunication, electronics, chemical, machinery, textile, etc. and composed of 45 failure and 73 success cases. The findings are not much different from those of previous studies done in the developed countries, but show some typical characteristics of new product development activities and the idea sources, information acquisition methods, type of information , incentives for idea generation, etc. of the firms in developing country like Korea. Especially the survival rate curve and the accumulative investment curve from the idea generation to commercialization phase show a little different behavior from the previous study, which also reflect the manpower, duration of each phase of the new product development process in the Korean firms.

최근 기후변화 대응 및 경제위기 극복을 위하여 세계 각국은 녹색기술 육성과 환경규제 강화를 통한 자국의 신성장엔진 창출 및 경기부양에 모든 국력을 총동원하고 있다. 이에 한국 정부도 새로운 성장동력산업의 창출 및 육성을 위해 녹색기술사업과 관련하여 미래 유망신기술을 보유한 중소기업들을 대상으로 2009년부터 민관 공통으로 신성장동력펀드를 조성하여 운용하고 있다. 하지만, 현재 선성장동력펀드는 글로별 경제위기, 대규모 출자금액, 투자대상 기업 발굴의 어려움 등으로 민간자본 유치에 많은 어려움을 겪고 있으며, 이에 펀드 운영 방식의 변경이 불가피하다는 지적을 받고 있다. 본 연구에서는 신성장동력펀드의 지속적인 성장 및 확대 추진을 위해 해외펀드 조성 및 운영 사례를 기반으로 신성장동력산업의 지속적인 육성 및 지원을 위한 정부지자체협력 펀드, 정부금융기관협력 인큐베이터 펀드, 정부대기업-중소기업 상생협력 펀드의 운영 방안을 제안한다. 본 연구는 신성장동력산업의 육성이라는 전략적 정책을 지원함에 있어 다양한 펀드를 제안함으로써 정책의 실효성을 높이는데 의의를 가진다.

IT는 한국의 경제성장에 큰 기여를 해왔으며 사회전반의 패러다임 혁신을 통해 생산성, 효율성, 편의성, 소통성을 증진시키고 삶의 양식에 전면적 변화를 가져왔다. 국민경제와 사회문화에서 지대한 의미를 지나는 IT는 다른 기술 또는 산업과의 융합이라는 새로운 변화와 혁신의 중심에 위치하고 있다. IT융합은 IT의 자체 고도화를 바탕으로 다른 분야의 기술개발과 산업발전을 견인하거나 새로운 산업을 창출하는 것으로 우리나라를 비롯하며 주요국에서는 자원과 역량을 선택적으로 집중하고 있다. 이 논문에서는 IT 융합과 관련된 주요국의 산업 전략 및 기술개발 동향을 파악하고 전문가 설문조사결과를 바탕으로 한국의 IT 융합역량의 수준을 평가하고 결론적으로 IT융합신산업육성 및 선도방안에 관한 전략적 제언을 하고자 한다.

사물인터넷이 국내외 다양한 산업에 정착되고 새로운 가치 창출이 이루어지고 있다. 특히 제조업의 경우, 한국 정부의 제조업 혁신 3.0 전략과 함께 스마트공장 개념으로 발전하여 경쟁력을 높이는데 사물인터넷이 큰 기여를 하고 있다. 이에 본 연구는 국내 제조업의 사물인터넷의 활용성을 파악하고자 한다. 새로운 분류 기준에 따라 산업연구원에서 정의한 10대 주력 산업을 6개의 세그먼트로 구분하였고, SWOT 분석을 수행하였다. SWOT 분석을 통해 도출된 각 요소들은 상호 연관성 분석을 통해 '강점과 약점', '기회와 위협'으로 나누었다. 이를 바탕으로 전략적 결정 그리드 포지셔닝을 수행하여, 6가지 세그먼트들이 사물인터넷을 활용하는 데에 있어 어떠한 상황에 있는지 분석하였다.

The importance of intangible assets have increased unprecedentedly with the advent of the knowledge-based society. Investment in R&D has contributed to the rise of productivity and firm-value in the capital markets. but it is very difficult to determine the economic benefits of R&D investment, due to elusive link between time requirements and the realization of firm value from R&D investment. This study examines the differential effects of R&D expenditure and patents on firm-value by industry. Patents are intangible, proprietary rights that develops new products, plays a crucial role in market competition and results in research and development activities. If firms get patents, their R&D expenditure is assumed to be successful. The study analyzes whether successful R&D expenditure has a significant effect on the firm-value. The study considers two industries : high-tech industries and low-tech industries. These industries are expected to have different effect on R&D expenditure and firm-vale. The results of the study indicate that the successful R&D expenditure increased the firm-value. Successful R&D expenditure in high-tech industries more increased the firm-value more than that in low-tech industries.

With swelling of Chinese Economic scale, the competitive environment is swinging over the north-east Asia countries, Korea, Japan, China, and Taiwan. As the result of this circumstance, each countries in this area has been reformed their industries. According to the expanding in ocean logistic. The trends of competition on Hub port is looking forward much more severe year after year to preoccupy in logistics competitive within this Area. On the other hand, considering competitive environment & swelling of Chinese Economic scale, the structural reforms are imperative in korea. Korea have to convert the traditional sects into new high added value sects. In these trends, provincial government also should look for the plan for reinforcement of Regional competitiveness. The focus of this study is to look for the reinforcement methods on regional competitiveness of Gyeongnam Provincial Government. First, competitive industries in Gyeongnam, and second, Masan Free Trade Zone will be surveyed from data. Finally, the effects of New Hub port developing in Pusan-Jinhae will be discussed.

This paper summarizes the size and output of the major animal industries in Australia and the feed resource available to maintain production. The most important feed source is pasture but there is also extensive use of cereal grains, pulses and by-products in the intensive animal industries and in supplementing the diet of grazing animals. These resources must be used in ways that ensure sustainable production. We outline a number of Decision Support Systems such as GrazFeed, GrassGro, and AusPig which play an important role in optimizing the way in which resources are used. Waste management with respect to mineral pollution of water courses and methane production as a greenhouse gas are important issues for the animal industries and are also considered.

In this paper, we proposed color stereo matching algorithm using dynamic programming. The conventional gray stereo matching algorithms show blur at depth discontinuities and non-existence of matching pixel in occlusion lesions. Also it accompanies matching error by lack of matching information in the untextured region. This paper defines new cost function makes up for the problems happening in conventional gray stereo matching algorithm. New cost function contain the following properties. I) Edge points are corresponded to edge points. ii) Non-edge points are corresponded to non-edge points. iii) In case of exiting the amount of edges, the cost function has some weight in proportion to path distance. Proposed algorithm was applied in various images obtained by parallel camera model. As the result, proposed algorithm showed improved performance in the aspect of matching error and processing in the occlusion region compared to conventional gray stereo matching algorithms.
