Early interceptive orthodontic interventions are often started in the developing dentition to guide normal occlusion. The simplest way to prevent eruption failure from deciduous tooth loss is to fix a space maintainer such as a band and loop. Band and loop space maintainer has several problems like cement loss, demineralization, locking of the adjacent tooth, and needs to take a pickup impression of the band. Computer-assisted design/computer-assisted manufacturing (CAD/CAM) space maintainer without band was developed to solve these problems. This case report describes successful eruption of the mandibular second premolar using CAD/CAM without a band.

When it comes to museumification, it has often been approached in terms of false history, placelessness or simulacra. However, this research aims at exploring the relation between the bodily-spatial performance of walking in the city and the museumification of urban space. For this, first it reviews theoretical discussions of walking as a bodily-spatial performance. Then, in the case of Daegu's Modern Street Tour and particularly focusing on the tour map, it looks at how the bodily performance of walking constructs the urban space of the tour as a museumified space. Finally, seeing the participants' blogs and other websites as another performative space, it examines how the bodily performance of walking reproduces the discourse and space of the tour in virtual space as well as in actual space. The study suggests the elusive assemblage of heterogeneous and multiple time-spaces immanent in urban space, which is different from the absolute and linear order of time-space in museum space.

Since 1970's, the rivers in industrial cities and metropolitan cities in Korea have been severely contaminated and the riverfronts have been to garbage yard, warehouses and sanitary facilities that produce low efficiency in urban land-use. As a result, riverfront in most cities became lost space and artificial area which composed of asphalt road, concrete riverbank and parking lot. However, Sustainable management is the main concept of riverfront development in 21st century. Also, in contemporary riverfront space, it is the pivotal paradigm that the development of eco-space and mixture of cultural space. Citizen require greener, more ecological and water-friendly space in riverfront of city. So, the purpose of this paper lies in suggestion for building sustainable development and management for riverfront in Korean city. For this purpose, this paper has reviewed the developmental trend of recent riverfront, has analyzed locational environment and land use of riverfront in city, has set policy and the strategy for sustainable riverfront.

Environmental design is the process of creating and suggesting a new culture retlectmg the spirits and scientific know ledges of an age, so il is important for a designer, who deals environment, to perceive the present trend of science, The goal of this study is to suggest a way to recover the vanishing image in current urban environment from the viewpoint of changing world-view, The process of this study is as follows. 1. According to spatial hierarchy, the role of each space and the importance of each space in correlation with human are considered. 2. The method to undersk, nd the space from the viewpoint of new paradigm and the direction of environmental design's access are suggested. 3. The notion that introduction of semi public space In urban environment is consistent with new paradigm is demonstrated and the semi public space's role of stimulation of urban activity is emphasized. The result of this study shows a possibility that semi public space, introduced by understanding of a space on the basis of new paradigm, expands the territory of life and overcomes tile negative environmental problem like disorder, increase of entropy.

The spaces of port and urban in a Port City have different space characteristics substantially, but those are required to be developed interdependently. Degradation and loss of the sense of place in the existing spaces caused by decline of natural function have an adverse effect on the revival of local economy as well as make worse image of the entire city. In some developed countries, therefore, many researches on the port spaces lagging behind the times due to changes of the characteristics and function of port spaces have been conducted continuously for a long time. This study aims at seeking a device how the domestic hinterland could be utilized as efficient spaces having the characteristics of outskirts space and port city interface through the application of characteristics of the interface space of port city, capable of playing a role as buffer zone between the port space and the city space.

A patient with severe periodontitis has causative factors that cause pathological tooth movement, the occlusion is disintegrated, and the vicious cycle of worsening periodontitis is repeated. In particular, when pathological tooth movement occurs in the maxillary anterior region, the patient has an aesthetic sense of atrophy, and the quality of life was reduced. Therefore, when orthodontic treatment was added to patients with severe periodontitis, it promotes the formation of new bone, reduces periodontal cysts, and obtains clinical attachment, which leads to favorable results in prosthetic restoration, thereby enabling ideal occlusion, function and aesthetics. Periodontal treatment, orthodontic treatment, natural tooth restoration, and implant prosthesis were planned for patients with pathological tooth movement in the anterior region due to loss of occlusal support in the posterior region. As a result, an ideal restoration space was secured, a stable restoration of occlusal contact was formed, and the maxillary anterior teeth were aesthetically improved.

To rehabilitate a patient with inappropriate occlusion due to posterior support loss, it is necessary to achieve an appropriate occlusal vertical dimension and create prostheses that demonstrate stable occlusion at the centric relation for full mouth restoration. This case shows full mouth rehabilitation in a patient with missing posterior teeth and tooth wear, achieved through implant-supported prostheses and zirconia full-veneer crowns. To assess adaptation to the increased occlusal vertical dimension, an occlusal splint and temporary restorations were secured. By fabricating the definitive restorations based on the anterior guidance of the temporary restorations, stable occlusal rehabilitation was successfully achieved.

Gradual teeth wear is normal physiological progress, severe tooth wear can causes dysfunction, occlusal plane disharmony and esthetic problems. If additional space is needed for prosthetic restoration due to severe attrition, full mouth rehabilitation with increase of occlusal vertical dimension may be considered. In this case, 72 year old male patient with severe worn dentition, irregular gingival zenith and deep anterior bite was treated by full mouth rehabilitation for regaining the space for restoration, improving relationship and esthetic of anterior teeth. Provisional restoration obtained by systemic analysis, diagnosis and re-evaluation for a sufficient time was replicated to final restorations through double scanning technique using monolithic zirconia blocks. Satisfactory functional and esthetic outcomes were obtained.

In this paper we propose a new method of security visualization, VisFlow, using traffic flows to solve the problems of existing traffic flows based visualization techniques that were a loss of end-to-end semantics of communication, reflection problem by symmetrical address coordinates space, and intuitive loss problem in mass of traffic. VisFlow, a simple and effective security visualization interface, can do a real-time analysis and monitoring the situation in the managed network with visualizing a variety of network behavior not seen in the individual traffic data that can be shaped into patterns. This is a way to increase the intuitiveness and usability by identifying the role of nodes and by visualizing the highlighted or simplified information based on their importance in 2D/3D space. In addition, it monitor the network security situation as a way to increase the informational effectively using the asymmetrical connecting line based on IP addresses between pairs of nodes. Administrator can do a real-time analysis and monitoring the situation in the managed network using VisFlow, it makes to effectively investigate the massive traffic data and is easy to intuitively understand the entire network situation.
