Recently, the User Created Contents is rising up. Gearing with an era of the Web 2.0, The pre existed Potal and private web pages are having extensive changes, and the heart of the changes is just the contents what the users produce and spread by themselves. Therefore, there is an observation about the system of contents spread on Web media until nowadays, and the features, in this article. This paper will be intend to expect that the commonness between the examples of the current User Contents, technologies for User contents, and the possibilities for development.

In this paper, self-networking and replaceable structure in vector graphics contents are presented for wireless internet service. The wireless networks over 2G or 3G are limited in the sense of the speed and the cost. Considering these characteristics of wireless network, self-networking method and replaceable structure in downloaded contents are introduced in order to save the amount of data and provide variations for contents. During the display of contents, a certain data for the contents is downloaded from the server and it is managed appropriately for the operation of the contents. The downloaded materials are reflected to the original contents using replaceable structure. Also, the downloading and modification are independent of the play. In this implementation, the data consists of control data for control and resource data for image, sound or text. Comparing to the conventional methods which download the whole data, the amount of the transmitted data is very small since only the difference is downloaded. Also, during the play of the contents, the changes are adopted immediately. The whole functions are implemented in wireless handset and the various applications are discussed.

The heavy metal contents are more abundant in stream waters, paddy soils and rice plants in the vicinity of abandoned mines compared to the surrounding areas in the Kyungpook province. However, these contents tend to decrease with distance from mines, and show some variation under different geological and geochemical environments. The Sin-stream waters have high contents of Cu=4.9 ppm, Pb=0.1 ppm, Zn=3.5 ppm and other heavy metals (Ni, Co, Cd) at Dalsung abandoned mine and low contents of Cu=0.4 ppm, Pb=0.1 ppm, Zn=0.1 ppm and other metals= 0.002 ppm in the surrounding area. The high contents decrease in the downstream in the area of calcareous sedimentary rocks. The paddy soils have high contents of approximately Cu=51 ppm, Pb=83 ppm, Zn=211 ppm, and Cd=11.3 ppm in the vicinity of Gunwi abandoned mine but low contents of Cu=4.5 ppm, Pb=2.9 ppm, Zn=60 ppm and Cd=0.4 ppm in the surrounding area. The Dadeog abandoned mine also shows similar trends to Gunwi mine. The contents of heavy metals of rice plants are high in the roots but trends to decrease through stem+leaf and become low in brown rices.

Recently, as the public interests about the 3D printing technology are increased, various kinds of 3D printers are being released. But, they are limited to use because they cannot fabricate an object which is larger than the printer's printing volume. To relieve this problem, we propose an interactive 3D mesh editing system for 3D printing the object that is larger than the printing volume. The proposed 3D editing system divides the input 3D mesh using the user's line drawings defining cutting planes and it attaches various connectors. The output meshes are guaranteed to fabricate without post-processing. The printed parts can be assembled using the connectors. Our proposed system has an advantage that it can be used easily by non-professional 3D printer users.

The success of DMB is controled its contents. Existing broadcasting contents will be retransmitted to DMB in the early stage of broadcasting. However, they must be produced appropriately to the property of DMB. To make good DMB contents, it's very important for us to analyze characteristics of DMB and costumer behaviors of DMB service. In this research, We suggest a production method for DMB contents such as contents length, camera work, visual expression. Contents will be key factor in the success of DMB.

The purpose of this study is to find out the effects of AR digital contents on user learning context. More and more companies using digital contents for their products. Especially, some companies using AR (Augmented Reality) digital contents as a manual of their car. This Application affords diverse information to customers who want to know usage of its interface. Using this application, the study shows the effects of using AR digital contents on user's absorption, physical presence, immersion.

History documentaries in Korea have developed various forms of production techniques to overcome the limits of insufficient historical records and videos, and dramatic elements that make the viewers immersed. Through diverse production techniques, history documentaries can maximize the factuality, vividness, and informativeness, allowing the viewers to understand and share the historical events. This paper analyzed the "immersion and experience" techniques of the programs that have been the main turning points of the history documentary so far and produced and realized the virtual reality through utilizing "Uigwe", a 3D history documentary broadcasted on KBS which showed the possibility of applying the virtual reality technique as a new broadcasting contents format.

Recently, in computer graphics, researches on 3D animations have been very active. One of the important research areas in 3D animation is animation of human being. Implicit surface model is convient for modeling objects composed of complicated surface such as 3D characters and liquids. Moreover, it can represent various forms of surfaces using a relatively small amount of data. In this paper, we propose a method of facial model generation using Implicit Primitive.

The mineral contents were analyzed for apple juices by Inductively Coupled Plasma. The Mg contents of tested commercial apple juices ranged 6.27∼32.91ppm, Ca 15,95∼3.11.76ppm K231∼1148.02ppm Na 39.82∼115.68ppm and P 19.27∼304.02ppm. The mineal contents of model apple juice were Mg 29.83∼45.65ppm Ca 16.98∼30.98ppm K 814.28∼1,256.70ppm Na 19.88∼26.85ppm and P 25.88∼54.71ppm. respectively. Comparing mineral contents of model apple juices and commercial apple juice, Na, Ca and P contents of commercial apple juices were higher but Mg, K contents were lower than that of model apple juices. Among the mineral content of apple juices. K was the major element.
