Purpose The purpose of this study is to analize a psychological and behavioral mechanism for using profile picture management in digital service such as social network service. Profile picture management falls under metadata management and is performed only by those who want it. This means that it, is one of the typical makeup-type digital shadow works (DSWs) which have not been studied yet. Design/methodology/approach This study adopts ground theory method(GTM) as research methodology. GTM, which is one of qualitative methodologies, is for developing theories while most survey based methodologies, which are well adopted in much research for information systems, are for validation of theories. By interviewing ten users, the data are collected and analyzed by open coding, axis coding with paradigm model, and selective coding. Findings In result, 39 codes are found and classified into 29 sub classes and 15 classes. These 15 classes are organized by paradigm model which derives core code of profile picture management as 'voluntary management tasks to experience small pleasures with intermittent attention'. Finally, based on the paradigm model and the core code, the story line, which can explain profile picture management, is suggested.

In 2011, in the Olympus advertisement appeared a copy of 'Writing of Picture'. Usually, the verb of 'Shoot' is commonly attached behind the picture, but a new sentence was made connecting 'writing' into the picture in the advertisement. With entrance of the digital era, the digital devices became popular, and the behaviors people post messages and pictures together on the internet site also became popular. Whether we first take a picture and then make a writing later, or whether we first make a writing and then take a picture later, the meaning of 'writing' and 'shooting' is actually alike in the digital era. People now use various images and writings, at the same time, of the pictures in expressing their own selves positively. This soon means not only that the pictures are helpful for writings, but also that the delivery of the meaning is not carried out only by characters. To the digital natives who have grown within many images, this atmosphere is a natural thing. In the field of Korean language education, the study of making use of the pictures and media for writings is in progress.

Recently, with the spread of digital camera and PC cam, need of tools for display and manipulation of digital images have increased remarkably. These tools are called as digital album. Af now, people want to see picture not alone in home but share with someone else. The purpose of this study is to develop a digital album, which is easy to use, easy to approach and has more function. Therefore people can see picture everywhere he want and management it. If computer is connected In Internet.

We have developed $16{\mu}m{\times}16{\mu}m$ digital micromirror array suitable for seamless-picture projection display system. This structure can improve the picture quality by making seamlesspicture image when combined with high-fill-factor microlens array to focus lights onto the mirror center. The fabricated micromirror shows excellent dynamic performances including the resonant frequency of 400 kHz.

Consumers changed to the subject to produce a digital contents as data transmission technique is advanced and a digital machine is diffused variously. Users are interested greatly in a user creative movie (UCM) production among various online contents. The UCM production method which uses the music and picture is the method that users make the UCM more easily. However, the UCM production service has the problem that any association does not exist in the music and picture and that the picture changes according to fixed time interval without the relation at a music rhythm. To solve this problem, we propose the UCM production method which uses a music analysis and picture analysis in the paper. A music analysis finds a picture change time according to the rhythm and a picture analysis finds the association of the picture. A music analysis finds strong parts of the sound which uses Root-Mean-Square (RMS). And a picture analysis classifies the picture as a scenery picture and people picture which uses structure simplicity of the picture(SSP) and face region detection. A picture analysis got correct result of 86.4% in the experiment and we can finds the association at each picture and arranges the sequence which the picture appears. Therefore, if we use a music and picture analysis at the UCM production, users may make natural and efficient movie.

Advancements in digital technology have caused significant changes to the tradition of creative educational activities. Such an with digital technology is prone to an error where digital technology itself becomes the goal, ignoring educational efficacy grounded on improved user experience and immersion. Previously, picture book-making activities for children allow them to actively participate in the process of book-making, and is often employed to instill reading habits as well as nurture linguistic abilities. Aside from such picture book-making activities, diverse efforts are being made for innovation in educational pedagogy through digital technology. However, as the goal of children's picture book-making activities is realizing creative education through expressions in language and pictures, digital technology should be considered in the viewpoint of fusion, not as a simple replacement to the traditional tools employed in children's picture book-making activities. This study examines previous researches related to children's picture book-making activities to propose contents and methodology allowing effective immersion by fusing digital technology based on a physical environment, from the viewpoint of fusion and integration. Expect this study will become a fundamental data in visualizing a practical integration of digital technology in future creative education.

This article takes the talk show "Beast Town" as an example to introduce the overall technical solution, technical difficulties and countermeasures for the combination of cartoon virtual characters and virtual studio technology, providing reference and experience for the multi-scenario application of digital humans. Compared with the live broadcast that combines reality and reality, we have further upgraded our virtual production technology and digital human-driven technology, adopted industry-leading real-time virtual production technology and monocular camera driving technology, and launched a virtual cartoon character talk show - "Beast Town" to achieve real Perfectly combined with virtuality, it further enhances program immersion and audio-visual experience, and expands infinite boundaries for virtual manufacturing. In the talk show, motion capture shooting technology is used for final picture synthesis. The virtual scene needs to present dynamic effects, and at the same time realize the driving of the digital human and the movement with the push, pull and pan of the overall picture. This puts forward very high requirements for multi-party data synchronization, real-time driving of digital people, and synthetic picture rendering. We focus on issues such as virtual and real data docking and monocular camera motion capture effects. We combine camera outward tracking, multi-scene picture perspective, multi-machine rendering and other solutions to effectively solve picture linkage and rendering quality problems in a deeply immersive space environment. , presenting users with visual effects of linkage between digital people and live guests.
