  • Recently, various augmented reality(AR) methods for monitoring situations in a remote factory have been proposed. The 2D manual with a classic method is not intuitive to understand and has limitations to provide to interact with objects to be repaired in the remote factory. In our paper, we present a guide method based on a virtual human expressed in augmented reality for the remote environment. Also, the remote factory environment was periodically captured through 3D reconstruction, our virtual human was adaptively matched to the built 3D environment. According to this paper, our method makes it possible to perform repairs quickly with the feeling of being with an expert. and it is possible to provide a visualized guide for troubleshooting in various fields such as factories, offices, medical facilities, and schools in remote environments.

  • In this paper, we propose a digital human content creation system. The digital human content creation system works with 3D AI modeling through whole-body scanning, and is produced with 3D modeling post-processing, texturing, rigging. By combining this with virtual reality(VR) content information, natural motion of the virtual model can be achieved in virtual reality, and digital human content can be efficiently created in one system. Therefore, there is an effect of enabling the creation of virtual reality-based digital human content that minimizes resources. In addition, it is intended to provide an automated pre-processing process that does not require a pre-processing process for 3D modeling and texturing by humans, and to provide a technology for efficiently managing various digital human contents. In particular, since the pre-processing process such as 3D modeling and texturing to construct a virtual model are automatically performed by artificial intelligence, so it has the advantage that rapid and efficient virtual model configuration can be achieved. In addition, it has the advantage of being able to easily organize and manage digital human contents through signature motion.

  • In this paper we propose a human body tracking method for application of smartphones. The conventional human body tracking method is divided into a sensor-based method and a vision-based method. The sensor-based methods have a weakness in that tracking accuracy is low due to cumulative error of position information. The vision-based method has no cumulative error, but it requires reduction of the computational complexity for application of smartphone. In this paper we use the improved HOG algorithm as a human body tracking method for application of smartphone. The improved HOG algorithm is implemented through downsampling and frame sampling. Gaussian pyramid is applied for downsampling, and uniform sampling is applied for frame sampling. We measured the proposed algorithm on two devices, four resolutions, and four frame sampling intervals. We derive the best detection rate among downsampling and frame sampling parameters that can be applied in realtime.

  • COVID-19 로 인해 마스크 착용이 필수적인 사회가 되면서 마스크를 착용한 상태로 얼굴 사진을 촬영하는 빈도가 증가하고 있다. 그러나 얼굴인식 기반의 보정 및 필터링 기능이 적용된 카메라 애플리케이션은 인물의 마스크 착용 유무를 인식하지 못하여 마스크로 가려진 영역까지 필터 및 색조 기능을 적용시킨다는 한계가 있다. 이러한 문제를 해결하기 위해 본 연구에서는 검출된 얼굴영역에서 마스크 착용 여부 및 마스크 영역을 판단하고 해당 영역을 제외한 나머지 얼굴 영역에 필터링 효과를 적용하는 기술을 구현하였다.

  • 최근 국내에서는 저탄소 녹색도시 조성의 일환으로 도시의 환경오염과 기후변화의 문제의 원인이 되고 있는 탄소 배출을 억제하고 고유가 시대에 에너지저감을 동시에 고려하는 저탄소 도시 조성을 통해 기후변화 시대에 대응을 추진하고 있다(국토해양부, 2009). 이러한 결과로 최근 도시내 물순환시스템(urban water circulating system or blue-network)의 구축이 요구되며 이는 자연의 생태 기능을 복원하고 오염부하를 저감하여 도시 환경의 건강성과 지속성 향상에 기여한다. 이러한 도시물순환시스템은 시민의 휴식 및 문화 공간, 도심열섬현상 완화, 재해방지, 생물서식공간(biotope) 제공 등의 기본적인 기능 이외에도 탄소배출 감소, 우수 저류공간 확보, 지하수위 유지, 비상용수 확보, 대기오염물질의 집진제거, 습지보전 및 생물종 다양성 확보 등의 주요 기능을 수행할 수 있기 때문에 구도심의 재개발 또는 신도시 개발 시 도시 어메니티(amenity) 증진에 널리 적용되고 있다(서울시정개발연구원 2003; 한국토지공사 2003). 남한산성을 포함하는 청량산 계곡수를 발원지로서, 공간적 범위는 장지천과 창곡천을 따라 약 3.5 km 서쪽으로 흘러 탄천에 이르기까지의 물길축(blue-network)를 기반으로 하며 총면적은 $6.8km^2$ 으로 서울, 성남, 하남의 3개 행정구역에 걸쳐있다. 내용적 범위는 현황조사(개발 컨셉, 하천분포현황, 인접지역 연계, 수질), 수량 및 수질 확보방안(물수지분석, 다중 수원 확보방안, 목표수질 설정, 부영양화 가능성 평가), 물순환시스템 구축(소하천 등과 연계 방안), 유지관리 방안의 순서로 진행하여 기본계획을 도출하였다. 현황조사 결과 본 사업대상지는 장지천, 창곡천, 학암천 등 3개 소하천이 서쪽의 탄천과 연결되어 있으며 동쪽은 산지로 청량산이 인접하기에, 주변 자연지형을 최대한 고려하여 물순환시스템을 계획하였다. 하천 유량은 기존 환경영향평가서, 하천 연계방안, 신도시 조성 관련기준 등을 종합적으로 고려하여 하류에서 각각 장지천 $10,087m^3/d$, 창곡천 $7,103m^3/d$, 복우천 $5,530m^3/d$ 의 유지용수량을 산정하였다. 도시 친수공간 확보와 어메니티 향상을 위해 지구내 수로(휴먼링)을 조성하여 장지천, 창곡천과 연계하였으며 주요 유지용수는 저탄소 녹색도시 건설에 부합하도록 우수을 활용한 함양지 및 계곡수로 조성 계획하였다. 또한, 인접한 장지천 및 창곡천 등 소하천은 지속적인 유량공급 및 양질의 수질을 확보하기 위해서 하상여과수를 검토 후 제안하였다.

  • The purpose of this study is to develop up-cycling fashion design methods centered on discarded denim material for the study of original up-cycling design methods. Up-cycling fashion design work was developed using digital clothing technology. This is a recent hot topic among sustainable fashion design methods. Up-cycling fashion design expression methods (categorized as dismantlement, collages, dépaysement, grafting, weaving, and tearing) were centered on design methods. These methods create various three-dimensional modeling effects in planar forms, whereby five pieces can be applied to the fabric and digitally produced. The results are as follows: First, the use of discarded denim fabric for the development of up-cycling fashion design pieces enabled the recycling of existing resources, provided solutions to environmental pollution problems, and provided expansion opportunities for design processes for sustainable fashion products that expand the design value of denim products and their utility. Second, new eco-friendly fashion designs that attempt to achieve diversity in modern fashion trends could be presented through formative contemporary fashion produced by up-cycling work products. Third, up-cycling fashion design work is expected to provide opportunities for eco-friendly fashion design methods. This will expand the value of sustainable fashion design by recycling simple waste materials through the use of three-dimensional digital clothing technology and further through the presentation of expanded life cycles that extend product planning, production, and life cycles.

  • The baby-tech industry, which combines IT with existing parenting product, is attracting increasing amounts of attention. Consequently various types of baby products incorporating functionality and design are being launched. In recent years, particularly as the market segments increases for babywearing products, parenting products that account for the child's comfort and parents' convenience are required. Therefore, this study examines the characteristics and consumer perception of babywear products, which are important for the emotional stability, development, and rearing of children. The study utilizes text mining and a network analysis by collecting unstructured text data. An examination of the network, based on the frequency of keywords for each babywear product and the degree of the connection to the centering index, revealed that consumers value convenience and price when purchasing products. The consumer perception and consideration factors that appear individually according to the product were also identified. In addition, studying body parts with high TF-IDF values revealed a difference in the body parts considered by consumers for each product. Lastly, through the visualization data based on the keywords that appeared in public, commonly appearing keywords, and those that appeared individually were examined. Through SNS, product characteristics as well as a new parenting culture that shared child-rearing routines were confirmed. This study suggests planning and marketing directions for the development of babywear products that meet consumer needs.

  • Unlike other leisure boats, a sailing yacht is propelled by wind power using sails that are controlled by the crew. Therefore, the ergonomic design of the equipment that the crew has to operate for sailing might be very important. However, it is difficult to find design rules and regulations for the equipment arrangement of a sailing yacht based on ergonomics. In this study, the arrangement design for the height and side plate angle of a winch for a sailing yacht was examined from an ergonomic design point of view. In a simulation, a Korean male in his 20s was selected as a human model for a grinder. The physical load was analyzed when he was operating a winch using a 3D human simulation. The lower back load showed the highest value when using the grinder at $90^{\circ}$ and $180^{\circ}$. Based on the results for the lower back load when using the grinder with various winch heights, it is suggested that the winch height from the cockpit floor to the top of the winch should be more than 40% of the height of the human operator. In addition, according to the results for the lower back load with various horizontal distances from the body, it is suggested that the side plate angle should be less than $16^{\circ}$.
