These days the copyright plays a significant role in various fields of creative works and it has expanded dramatically into unprecedented ways. In Korea, architectural works copyright cases are rare due to the lack of information and understanding of the architectural works copyright. Architectural works copyright can promote architects' creative activities and enhance the quality of architectural works as art. Nevertheless, there is little effort to advance the studies of architectural works copyright in the architectural design area. Under these circumstances, this research attempts to share the basic case laws and remedies for various architectural works copyright issues in the U.S. cases. This Article examines the Thomas Shine v. David M. Childs and Skidmore Owings & Merrill, LLP Case which is the most recent case as I could reach. This case is about a story between two architects, one is from a very prestigious architectural design firm and the other, once Yale Architectural student, now practices his design work as an up-and-coming architect. A close examination of this case will provide a legal and architectural spectrum of copyright. That is, it will make it more specific how to solve the copyright infringement. Artistic and technological contexts are overlapped in Architectural works copyright as its inherent characteristics. Therefore, different ways from other copyrighted works are needed to access the untangled equations of the architectural works copyright protection. In addition, more comprehensible and specific regulations that can impose a remedy more suited to the architectural works copyright violations are needed and they should enable architects to fulfill their architectural activities under wide range of copyright protection. Moreover, in prior to all efforts to handle those equations, fundamental knowledge of architectural works copyright is required to improve the copyright protection in the architectural design area as well as to provide for the globalizing design practice. Ultimately, all of these efforts will be rewarded when constant researches based on Korean and other countries' architectural copyright cases can support them and it would be great if this research can set the stage for resolving expected copyright conflicts within the architectural design area.

VR(Virtual Reality) and AR(Augmented Reality) devices are becoming more common, and the need for proper contents presentation techniques in such environments has been growing ever since the popularization of the devices. One of the contents is the spatio-temporal data, which has become more prominent since it could be both generated and consumed by a large number of ordinary users. In this work, the researcher analyzed the characteristics of spatio-temporal data as a source for visualization in VR and AR environment, and categorized prior visualization methods for such data, which were devised for traditional monitors. The researcher also reviewed the hardware specification of state-of-the-art devices, and examined the possibility of adopting the previous visualization approaches. This work is expected to contribute in designing spatio-temporal visualization for VR and AR environment by utilizing their unique characteristics.

Understanding the level of a person's perception of changes that have occurred on the face after orthodontic treatment is critical to the process of orthodontic diagnosis and treatment planning. The purpose of this study was to determine the level of perception of profile and frontal changes in lower facial height. Forty students attending art school participated in a study evaluating the level of a participant's perception of changes in the lower facial height. Participants compared computer-graphic frontal and profile photographs with balanced proportions and photograph simulations of 1, 2, 3, and 4mm changes in lower facial height from stomion to the chin. At least a 2 mm change in lower facial height for the profile view and 3mm in the frontal view was needed to be perceived after orthodontic treatment. The level of a person's perception of the change in lower facial height was more sensitive in the profile view than in the frontal view, and information about facial changes given prior to evaluation enhanced the level of perception.

The purpose of this study was to analysis the effect of form and hardness of outsoles on the motion of the lower extremity joints and on foot pressure during gait. The subjects were 15 women(mean age, $48.5{\pm}2.4$ years), who had no serious musculoskeletal, coordination, balance or joint/ligament problems within 1 year prior to the study. The pelvic tilt, joint angles at the lower extremities and the vertical ground reaction force(GRF) were compared during gait with 3 types of shoes (A, B, C) by using one-way repeated ANOVA(p<.05). During gait, the peak tilt angle and the range of motion(ROM) of the ankle and knee joints were found to be significantly different among the 3 types of shoes. The type C shoes showed a significantly lower mean second maximum vertical GRF than types A and B. The curved outsoles of type C shoes, which had a form and hardness different from those of A and B, was designed strategically for walking shoes to provide stability to the Additionally, type C induced the dispersion of eccentric pressure and made the center of pressure roll over to the center line of the foot.

The movement of characters in ceil animation is the art that gives the feeling of movement. The movement expressed naturally and well done makes the scene more dramatic and interesting. The history of 3D animation is not fully riped yet but it has shown powerful impact. The genre of 3D has come closer to us, yet it has given freshness and problems at the same time. One of the problems is the awkwardness of movement. Overplaying, stretching and squashing of character, was extremely difficult to accomplish using the prior technique of 3D so! ftware. It was not very effective so animators have avoided doing it. However, advanced technique of 3D software, so to speak, ‘stretch and squash’, overcomes the limitation of movement. The new form of character animation can be accomplished. The theme of this paper is about the analysis and comparison of ‘stretch and squash’ in cell and 3D animation.

The implied obligation under the contract of affreightment not to carry dangerous goods without prior notice to the carrier applies to the contractual relationship between the charterer and the owner under charterparties. The charterers will be in breach of an implied undertaking under the common law if they load dangerous cargoes without making notice of dangerous nature of them to the owner. It is indicated to be necessary to change the term "shipper" to "charterer", with relation to such implied obligation, where the Hague/Hague-Visby Rules are incorporated into the charter, however, it is not so apparent where an actual shipper is involved. So long as an actual shipper could be identified, the shipper rather than the charterer shall be responsible for damages arising from the dangerous nature of the cargo itself. In this case, the actual shipper is interpreted to have an implied contractual relationship with the carrier just by the act of delivering the cargo to the carrier for loading. If the vessel were damaged by shipment of the dangerous cargo under charterparty, the carrier can claim against such damages based on the contractual obligations under charterparties: "implied and expressed duty not to ship dangerous cargo without notice to the carrier"; "Art.IV.6 of the Hague/Hague-Visby Rules"; "Indemnity Clause" and "Redelivery Clause". The carrier has the conventional right under the Hague/Hague-Visby Rules to land, destroy or render the goods innocuous where the dangerous cargo threatens the means of transport or other interests on board. When the carrier has not consented to make the shipment, the carrier's disposal right could be exercised without limitation. However, where the carrier has consented to make the shipment of the dangerous goods with the knowledge concerned, the right of disposal of such goods should be exercised with limitation.

The research deals with the changes of the laws related to gifted education focusing on the Marland Report. As result, contrary to conventional argument for the beginning of legal ground for gifted education, 1958's National Defense Education Act(P. L. 85~864) which stipulated the article for 'identification and encouragement' for 'able students' can be said the first legislation of gifted education in the level of federal government. In the case of definition of the gifted, prior to 1972's Marland Report, there was the first legal definition in the Section 806 of the Elementary and Secondary Education Act(P. L. 91~230, 1970), which said "Children who have outstanding intellectual ability or creative talent". However Marland Report expanded the realm of the gifted from the area of intelligence to the area of leadership, art and psychomotor ability. On the basis of Marland Report, in 1974 the Office of Gifted and Talented was set up in the Department of Education for dealing with gifted education in federal. Further, Marland emphasized the importance of stipulating article related to funds for gifted education in law. Without manifesting funds for gifted education in law, he knew very well how hard it was to practice gifted education in reality. This implies that regulation funds for gifted education is crucial for effective actualization of gifted education.

In this study, the effect on the zinc nuclei crystallization caused by changes preprocessing of the zinc crystalline glaze preparation has been studied. The mechanism of the nuclei formation in the crystalline glaze and development of the nuclei by studying the preprocessing step was explained. The preprocessing step was improved by altering mixing process of the materials prior to sintering: number of sieving dispersion process and ultra-sonication prove tests with various duration of sonication. According to the result, the sieving and sonication of the starting materials facilitated the interface reactions of $ZnO-SiO_2$ from $680^{\circ}C$ where low temperature willemite is formulated, and altered Si bonding for the easier bonding between Zn-Si. In other words, solely sieving was enough to accelerate the formation of willemite in low temperature. When the particles were distributed evenly by sonication, the willemite formation was even more significant.

Purpose: Currently, using perforator artery flaps especially anterolateral thigh flaps are widely used for reconstruction of extremities, head and neck. Obtaining a precise anatomical picture prior to operation will translate to a more accurate, efficient and safe procedure. Authors used 3D-image work up via 64-slice MDCT to make a more precise preoperative plan. Methods: A total of 10 patients underwent soft tissue reconstruction with anterolateral thigh flap from December 2006 to December 2007. The 64-Channel MDCT (LightSpeed VCT, GE, USA) was used and 3D images were reconstructed. Findings from MDCT were applied to the preoperative planning and confirmed with intraoperative findings. Results: The average number of perforator arteries from lateral circumflex femoral artery was 2. The average lengths of vascular pedicle from the origin of lateral circumflex femoral artery to the first and second perforator artery were 11.0 cm and 20.0 cm, respectively. The average diameter of the pedicle artery was 2.2 mm. The locations of the perforator arteries were mapped and localized on the body surface based on the MDCT result. These were confirmed through direct visualization intraoperatively. Conclusion: MDCT has an advantage of obtaining accurate images of the general anatomy and even fine structures like perforator arteries. By using this state-of-the-art diagnostic imaging technique, it is now possible to make an operative plan safely and easily.

Security of information during transmission is a major issue in this modern era. All of the communicating bodies want confidentiality, integrity, and authenticity of their secret information. Researchers have presented various schemes to cope with these Internet security issues. In this context, both steganography and cryptography can be used effectively. However, major limitation in the existing steganographic methods is the low-quality output stego images, which consequently results in the lack of security. To cope with these issues, we present an efficient method for RGB images based on gray level modification (GLM) and multi-level encryption (MLE). The secret key and secret data is encrypted using MLE algorithm before mapping it to the grey-levels of the cover image. Then, a transposition function is applied on cover image prior to data hiding. The usage of transpose, secret key, MLE, and GLM adds four different levels of security to the proposed algorithm, making it very difficult for a malicious user to extract the original secret information. The proposed method is evaluated both quantitatively and qualitatively. The experimental results, compared with several state-of-the-art algorithms, show that the proposed algorithm not only enhances the quality of stego images but also provides multiple levels of security, which can significantly misguide image steganalysis and makes the attack on this algorithm more challenging.
