Non-linear editing is an editing method that, unlike linear editing, enables users to insert a new frame between existing frames. Non-linear editing systems are systems that support such method, and are composed of a computer, a software and a capture board that inputs/outputs video signals. Non-linear editing is used for modern television broadcasts and movie productions. Recorded footage and various graphic sources are combined into one visual content through a non-linear editing system. In this paper, we will look into functions of various non-linear editing softwares (mainly the most common of all; Adobe Premiere) as well as their merits and demerits during the editing process, and will also discuss their future Improvement direction.

This study examines how the unobserved heterogeneity of workers, measured by residuals of the wage equation, affects the entry into self-employment using KLIPS 1998-2008. Following Joona and Wadensjo(2013), we treat the residuals as unobserved ability and find that both workers with higher and lower ability are more likely to become self-employed. However, this U-Shape relationship no longer holds when the sample is divided into males and females. The study also finds that the relationship between ability and entry into self-employment has changed over time, and that ability is positively associated with the performance of self-employed.

Traditional methods for the extraction of the environmental factors of waters in which environmental change is severer than in the land can not examine closely the changed phenomena because of the lack of equipments, manpower, time and cost, etc. Therefore, new practical and efficient methods are required. The research for the method to manage environment of the waters with remote sensing technology was needed. This study examined the interrelations between the data by an on-the-spot survey and Landsat TM data and presented the model for extracting factors of water quality with regression analysis and experimental formula.

Wireless power transfer is more convenient than wired power transfer, but has a shorter transfer distance and lower efficiency. In addition, it is difficult to charge multiple devices simultaneously. In this paper, we propose a method of magnetic beam forming by using multiple transmitters in order to increase transfer distance and improve efficiency of wireless power transfer. To do this, the relationship between the transmitter coil current and magnetic field at the center of receiver coil is modelled, and calculate the optimal transmitter coil current using the characteristics of the pseudoinverse. Finally, the validity of the proposed method is verified by simulation.

This paper has analyzed recognizing performance depending on the size of iris codes extracting by iris recognition algorithm using scale-space filtering. The iris images were created through pre-processing, the features were extracted by scale-space filtering, and the codes of 16 sizes were generated. The generated code's performance was compared for each code to calculate FAR and FRR by matching method utilizing Hamming distance. Every code had little overlapping portion between same person and other persons group so that the proposed algorithm's superiority was proved, and the performance of iris codes was analyzed for each size focused on convenience to use when implementing in realization. In addition, the iris codes suitable to iris recognition system that is high-reliable and is able to reduce user's inconvenience due to mis-rejection has been presented considering for commercialization.

This paper presents the displacement behavior safety of hollow shafts with an equivalent volume for various cross sectional area using a finite element method. The FEM results indicate that the hollow shafts with X-type or Y-type columns between outer tube, middle tube and inner tube may reduce a maximum displacement at the middle length of hollow shafts. Especially, the load-bearing column of X-type or Y-type hollow shaft is directly connected between outer tube and inner tube without a shift for reducing the vertical displacement. And increased thickness of a load-bearing column is recommended for reducing the vertical displacement and increasing the displacement behavior safety for an equivalent volume of a hollow shaft.

Todays many image digital media are in existence. Image digital media are connecting communication closely between receiver and transmitter. Development of image digital media enabled intensive image communication through internet and communicative media. Development of these image digital media brought visual information transmission and time reduction. Image digital media is connecting producers and consumers as indirect intermeditation called advertisement. Development of image digital media made field called motion graphic. Development of motion graphic made a lot of image technique and effect to enable. These ads. images are also operating or performing sensitive-communication by stimulating desire of consumers. An investigator in this study will be in search of an effect and an operation that motion graphic as a field of image expression technique gives insentive communication through an intance investigation.

The past interactive art was only attempted through interdisciplinary study of art and science. As it goes to the digital age, however, the artistic methods based on digital technology have been gradually increasing in combination with other media in various ways. This paper analyzes how spectators' individual selection of viewing-route increases the interaction between spectators and interactive art work by focusing on $\ulcorner$Meta 4Saisons$\lrcorner$. In the process of route selection, each spectator selects his/her own viewing-route almost different from the others', respectively. This individual viewing-route makes each spectator placed in a position of individual interaction, thus leading him/her to the experience of various feelings through the act of immersing in the interactive art interface.

An optimal fuel manifold is suggested to improve the cooling performance of injector face plate. The cooling performance at the center area of the injector face plate is to be augmented while the spatial injection uniformity is maintained. The comparison of the cooling performance of 7 candidates gives the conclusion that the dividing plate from 2-3 injector row to 9-10 injector row is an optimal. The maximum face plate temperature decreases by $27\%$ while the injection uniformity is close to that of the original design. The pressure drop in the fuel manifold of the optimal design is also same as the original design.

IT조선 융합의 목적은 조선산업에 IT기술을 접목해 조선산업의 초인류화를 달성하여 향후 5~10년 후에도 조선강국을 유지하고자 하는 데 있습니다. 이를 위해 정부에서는 제품의 고기능화 및 제조업의 고부가가치화를 위해 IT산업의 주력산업과 융합을 통한 10대 전력산업 중심의 이행계획으로 'IT융합 발전 전략'을 마련했습니다. IT조선 융합 분야에서는 IT융합을 통한 선박건조(Digital Shipyard), 선박통합통신망(SAN)이 적용된 지능형 선박(Smart Ship), 항로최적화 등을 위한 선박운항 기술개발 등이 고려될 수 있습니다. 국제적으로 EU, 미국, 일본 등에서 대형 프로젝트를 통해 기술개발을 완료하고 e-Navigation 정책의 국제적 합의 도출을 기다리는 상황입니다. e-Navigation은 선박의 안전항해를 실현하기 위한 방법으로써 선박에 사용되는 IT기자재의 표준화와 항해사의 의사결정을 도울 수 있는 도구 개발에 핵심을 두고 있습니다. 이를 위해 선내 모둔 기자재는 네트워크에 연결되어 선박의 항행정보와 선박기자재의 운전정보 등이 실시간으로 모니터링 되고 용이하게 제어되어야 하며, 이러한 정보는 육상에서도 모니터링 되고 필요시 육상에서 항해사의 의사결정을 도울 수 있어야 합니다. 정보교환을 위해서는 선박과 육상(Ship-Shore), 선박과 선박(Ship-Ship) 사이에 끊임없고 신뢰할 수 있는 통신채널이 유지되어야만 가능합니다. 이를 기반으로 e-Navigation의 최종 실현목표인 해양환경보호 및 항해 안전과 선박의 안전을 달성할 수 있으므로 표준화 분야도 이 범주 내에서 이루어져야 할 것입니다.
