스마트폰은 3R(Real time, Reach, Reality)을 통해 개인 기업 사회를 변화시킬 것이다. '언제 어디서나' 인터넷으로 무한한 정보를 이용할 수 있고 메신저, 인터넷 커뮤니티 사이트 상시 접속 등을 통해 실시간 커뮤니케이션을 수행하는 '속도의 경제'가 가속화 될 것이다. 특히 ICT 기술은 여성의 사회진출과 경쟁력을 증가시켜 여성주도 시대의 도래를 앞당기는 데 기여할 것으로 전국 여자대학교의 ICT개설 교과목의 파악 및 분석을 통해 향후 여성과 고령자의 편의를 위한 ICT 교과목 개발에 일조하고자 한다.

CG 기술의 발전으로 실사 이미지 위에 3d 애니메이션을 적용하는 실감나는 영화를 많이 볼 수 있다 그러나 아직까지도 실사 이미지와 3d 애니메이션 합성은 그래픽 아티스트의 수작업이 많이 필요하다. 본 논문에서는 자연 환경을 포함하는 실사 비디오에서 영상 분석 기법을 적용한 혼합 현실 시스템을 제안한다. 비디오 프레임에서 하늘, 바다 등 일정한 칼라 패턴을 가지는 영역을 분류하고 이 영역에 대해서 그래픽 객체를 삽입한다. 시스템의 각 단계에서 사용자 인터페이스를 제공하여 필요한 입력값을 제공받는다. 본 연구에서의 기법은 간단한 그래픽 입력 과정 이외에는 대부분의 과정이 자동으로 처리되므로 혼합 현실이 방송, 영화 특수 효과 등의 작업에 편리하게 이용될 수 있다.

Structural analysis and design of steel frames is usually conducted under the assumption that beam-to-column connections are either fixed or pinned. In reality, each connection possesses a certain rotational stiffness. In this study, structural analysis program is developed, which takes into account the nonlinear behavior of framed structures including flexibility of semi-rigid connections and member geometric nonlinearity. Effective semi-rigid connections for a 6-story unbraced steel frame are suggested and the effect of flexible connections on the behavior of the structure are studied.

In the present study, which is currently operating domestically and internationally, from the Technical Standards for Flight Safety of Light Sport Aircraft and certification system through a comparative analysis of the LSA Category Airworthiness Certifications documents. In particular, an aircraft type analysis of FAA certified S-LSA that the speed greater than 120 knots LSA manufactured without United States of America. Through the analysis, we presented a revised plan to activation of the domestic aviation leisure sports and the development of the Light Sport Aircraft industry in reality.

The general method of structural analysis for building structures has been based upon the assumption that all dead loads are imposed on a building simultaneously throughout the entire structure. In reality, buildings are built floor by floor or a few floors at a time. The construction dead load is applied gradually onto the structure as the structure is being erected. The prevailing commercial software for structural analysis used to date have resulted in the representation of inaccurate structural behaviors. The actual construction sequence and the loading of the structure ere not properly represented in the analysis. This paper identifies the source of the errors and develops the algorithm to account for the differential column shortening due to construction dead load based upon a given construction sequence

This study tried to analyze the keywords of the papers published in the Korea Safety Management Science by using the social network analysis. In order to extract the keywords, information on journal articles published from 2018 to 2021 was extracted from the SCIENCE ON. Among the keywords extracted from a total of 129 papers, the keywords with similar meanings were standardized. The keywords used in the same paper were visualized by connecting them through a network. Four centrality indicators of the social network analysis were used to analyze the effect of the keyword. Safety, Safety management, Apartment, Fire hose, SMEs, Virtual reality, Machine learning, Waterproof time, R&D capability, and Job crafting were selected as the keywords analyzed with high influence in the four centrality indicators.

In this study, the degree of motion sickness displayed according to actions in virtual reality is measured based on the SSQ tool, a measuring tool, and factors and symptoms affecting cyber motion sickness are investigated through comparative analysis. In the first experiment, the operation method experiment, the simple operation method is measured to be highly affected by the Nausea factor. As symptoms of this, nausea, burp and headache symptoms were developed. In the second experiment, the larger the body rotation radius, the higher the motion sickness was measured, and the greater the influence of Nausea factors. Symptoms of this were the symptoms of burping, headaches, and a full head. In the third experiment, the physical mobility experiment, motion sickness was measured highly in the non-action controller. It was measured to be greatly affected by the Nausea factor. Symptoms of this include fever, headache, and a full head. Through this study, we found that the more fixed and simple the body is operated in virtual reality, the more sensitive the user is to motion sickness, and the larger the radius of rotation, the more sensitive it is to motion sickness. This study is meaningful in identifying factors and symptoms that affect motion sickness and VR manipulation, and is expected to be used by developers in the future to recognize the degree and symptoms of motion sickness of users and to develop content.

The purpose of this study was to analyze representations of fatherhood of childcare entertainment reality programs. For this purpose, two episodes of of MBC were analyzed by semiotic analytic methods, especially, signs, images, combined level of significations, etc. The results indicated that fathers of the programs reflected modern ideal images of feminist fatherhood in which fathers cooperated to care children with mothers, and played the role of intimate friend-daddies, daddies as friends. A post-modern male ideology was inherent in those fatherhood changes. Those fathers in this program intermittently exposed narratives of inexperienced fathers while dedicating themselves to cooperative childcare adequate to the purpose of the program, suggesting that it would reproduce the mother-childcare ideology as a result. Furthermore, although such reflected changes towards fatherhood enthusiastically involving in childcare represented the modern ideal fatherhood, it is still identified that gender stereotypes, gender-based discrimination and patriarchal male ideologies were inherent in the ways of their guiding children. In short, such trend of friend-daddies did not imply an revolutional change from male-centered patriarchal family structures to male-female cooperated family structures.
