Interest about social security has recently increased in favor of safety for infrastructure. In addition, advances in computer vision and pattern recognition research are leading to video-based surveillance systems with improved scene analysis capabilities. However, such video surveillance systems, which are controlled by human operators, cannot actively cope with dynamic and anomalous events, such as having an invader in the corporate, commercial, or public sectors. For this reason, intelligent surveillance systems are increasingly needed to provide active social security services. In this study, we propose a core technique for intelligent surveillance system that is based on swarm robot technology. We present techniques for invader enclosing using swarm robots based on multiple distributed object environment. The proposed methods are composed of three main stages: location estimation of the object, specified object tracking, and decision of the cooperative behavior of the swarm robots. By using particle filter, object tracking and location estimation procedures are performed and a specified enclosing point for the swarm robots is located on the interactive positions in their coordinate system. Furthermore, the cooperative behaviors of the swarm robots are determined via the result of path navigation based on the combination of potential field and wall-following methods. The results of each stage are combined into the swarm robot-based invader-enclosing technique on multiple distributed object environments. Finally, several simulation results are provided to further discuss and verify the accuracy and effectiveness of the proposed techniques.

In this study, we tried to build a model which can deal with the efficient and effective operation of electric power industry, especially focused on the nuclear industry. Here, SD(system Dynamics) approach is used to visualize the underlying phenomenon of the nuclear power industry. SD is a methodology for studying and managing complex feedback systems, such as one finds in business and other social systems, The span of SD applications has grown extensively and now encompasses work in corporate planning and policy design, public management and policy, biological and medical modeling, energy and the environment. Recently, according to the report from KEPCO(Korea Electric Power Corporation), they are considering delaying a new power plant construction. It may be based upon business fluctuation downsized from Korean economic crisis in 1997 and freezing of construction funds due to unstable foreign exchange rate. At this point, we need desperately a kind of strategic model that would contribute to cope with the current business situation, energy generation, Production, and resulting Pollution. Specifically, this model, using SD approach, starts with the detailed drawing of influence diagram, which describes those relevant key points on nuclear power generation systems in electric power industry of Korea. These include such (actors as the operation of nuclear industry and parameters related to the decision making for business policy. Based upon the above-mentioned influence diagram drawn, we developed SD simulation model to evaluate and analyze strategic management of KBPCO. Based on our analysis, we could demonstrate how simulation model can be applied to the real electric power generation in Korea.

RnD Service기업은 혁신을 지원하는 기업이며 비즈니스생태계를 촉진하는 바, 우리는 첨단산업의 활성화를 선도하는 RnD Service기업에 대한 사례연구를 통하여 독립경제로서 RnD Service기업을 확인할 수 있었다. 기업보고서 및 제반 인터뷰 통해서 RnD Service기업의 역할을 파악하고 RnD Service기업의 생성과 혁신과정을 분석하였다. RnD Service기업은 독립된 경제이지만 비용 극복이 어려워서 대학이나 연구기관에 종속될수록 지역의 혁신이 늦어진다는 우려도 있기 때문에 지역혁신의 주체로서 RnD Service분야는 제반 산업과 동반하여 성장할 수 있도록 RnD Service기업의 독립적인 기술사업화에 관심을 두어야 한다. 연구결과에 의하면 대전의 RnD Service의 비즈니스 모델은 대학이나 공공기관에 종속된 발전이 아니라 기업과 기업 간의 독립된 기술개발모델로서 혁신을 가져오는 주체로 성장해가는 고무적인 결과가 나타난다.

The present study observes collaboration methods in which 3D printing was a part of the fashion manufacturing process, expression methods of such cases, and their ripple effects. As a result, the three types of collaborations between fashion designers and other industry fields, fashion brands and 3D printing companies, and fashion designers and artists. Case analysis results and ripple effects found according to each collaboration method were as follows. First, in collaborations found were between fashion designers and other industry fields, 3D printed fashion works with futuristic images were seen through the fusion of future industries, which claim to support cutting edge digital technology, and creative fashion design. As they were mainly collaborations between automobile industries with cutting edge images or digital related industries and fashion designers, they were expressed as a new form of experimental clothing, and were used as strategies to improve future corporate images of the high tech industry. Second, in collaborations between fashion brands and 3D printing technology businesses, the sporting good brands and the shoe industry attempted to let their products be known through the promotion of functional material or ergonomic technology. While they emphasize practicality by mainly using flexible material, they were mainly proposed as functional sporting goods for famous players or as shoe accessories, so methods are still used for public distribution as brand promoting marketing strategies. Third, with collaborations between fashion designers and artists, creative pieces were shown through the grafting of 3D printing technology, the artistry of artists, and the experimentation of fashion designers. In particular, the innovative value of fashion as art was created through the union of the artistic 3D modeling technology support of artists and the creativity of designers. Like this, 3D printing fashion can graft the cutting edge nature of fashion to other industry fields through collaborations, enhancing pacesetting images, and in the fashion field, it can improve possibilities for innovations in the fashion industry through the support of 3D printing technology businesses and artists, raising expectations towards future human living.

2005년 디자인보호법 개정으로 서체가 지적 재산으로 보호받게 되고 정보통신과 모바일 기기의 발달로 서체개발이 활발해 지고 있다. 기업에서는 기업 아이덴티티의 개념으로 전용서체를 활용하는 비중이 높아 졌으며 2010 디자인 서울 프로젝트로 서울시 상징서체를 만들면서 전용서체에 대한 관심이 높아졌다. 이에 따라 마케팅 전략이자 디자인 상품으로써 전용서체에 대한 연구가 필요한 시점이다. 본 연구에서는 기업의 전용서체가 브랜드 이미지에 미치는 영향을 분석하였다. 전용서체를 보유하고 있는 기업의 브랜드 이미지를 평가하였으며 이를 통해 기업이 전용서체를 보유하고 있다는 사실 자체가 해당브랜드를 창의적인 이미지로 인지하게 하는 요소로 작용 할 수 있다는 결과를 도출했다. 또한 전용서체를 개발하는 활동에 대해 설문 응답자들은 공익적인 활동으로 평가하며 전용서체가 CI와 같이 기업을 상징 할 수 있다는 의견에 긍정적인 태도를 취하고 있었다. 인지과학 분야의 문헌 연구를 통해 전용서체를 통한 커뮤니케이션이 일어나려면 서체에 대한 선택적 주의가 뒷받침 되어야 한다는 점을 밝히고, 재인실험을 통해 서체의 반복적인 노출이 전용서체 인지에 도움이 된다는 사실을 확인하였다.

The recent domestic construction market is in a difficult situation due to reduction of the government's SOC budget and new orders from public-sector, and the deterioration of housing supply situation in the private sector etc. In addition, the number of disasters in the construction industry has increased in recent years with 26,570 people (up 5.7% from the previous year) in 2016, unlike other industries that are in a declining trend. As such, the construction industry has unique characteristics and problems such as high industrial accidents rate, abnormal subcontracting structure, excessive working hours and work intensity. As a result, the construction workers have a lot of job stresses. Job stress has been recognized as one of the major causes of industrial accidents and many researches have been conducted on that. However, most of the researches were about the factors that induce job stress and how these factors affect disaster occurrence, job satisfaction, job performance, turnover intentions, and job exhaustion. The purpose of this study is to investigate the effect of positive psychological capital on job stress, which is emerging as a new human resources development paradigm useful in corporate management in order to find ways to reduce job stress. To do this, 347 data collected from construction workers in Daejeon, Sejong, and Chungcheong provinces were analyzed using statistical package(IBM SPSS 22) for basic statistical analysis, reliability analysis, and regression analysis. As a result, positive psychological capital has shown an alleviate effect on job stress. In particular, the higher the optimism, hope, and resiliency of positive psychological capital, the lower the job stress. However, the higher the self - efficacy, the higher the job stress.
