  • A ner general multi-layer area router, called DINOSAUR, is presented in this paper. DINOSAUR can route various types of routing areas, such as L-shaped channel, switchbox with/without obstacles, and rectilinear area with/without internal modules/terminals. The DINOSAUR algorithm consists of three major stages: layerless maze routing, layering by coloring, and rip-up and reroute. In layerless maze roution stage, the route of each net is determined by modified maze algorithm without taking the conflicts(short. circuits) into account. In layering by coloring stage, the layer of each net is determinde by a heuristic coloring algorithm. When the conflicts are not removed, rip-up and reroute process is invoded. In rip-up and reroute stage, the conflicts are removed iteratively. Many test cases have been run, and on all the benchmark data known in the literature DINOSAUR has performed either better than or comparable to the other routers.

  • This research aims to develop cultural products for professional sales after producing creative products utilizing dinosaur characters, which are the representative exhibited item of dinosaur-centered museum. There are seven museums in Korea whose theme is dinosaur. There are three dinosaur museums among them, Goseong Dinosaur Museum at Kyungnam, Mokpo Natural History Museum, and Seodaemun Museum of Natural History. While inspecting cultural products within the museum shops of these three museums, general products occupy more than 80% of all the products rather than products related to dinosaurs, and has a problem that most products are decorative ones. This resulted from that enterprises supplying these products are not professional ones and are irrelevent to cultural industry; as result, purpose of conveying culture through products is lost. This research develops dinosaur characters utilizing computer 3D techniques in order to imbue unique characteristics to dinosaur museums and informing cultural speciality of our country. In addition, this research presented design method of cultural products by grafting traditional symbols onto these characters, and actually produced 11 items of 5 kinds: toys(dolls), clothes(T-shirts, pajamas, socks), stationery(notebooks, memo), accessaries (bags, umbrellas, handkerchief), and others(cups). On the items above, dinosaur characters are variously utilized in form of printing, embroidery, and stickers by using computer 3D technique. A cultural product is a tangible form which could show variety of cultural characteristics of our nation that could spread the culture through the consumers, and such type of purchasing could increase values of cultural industry by creating economic profits; such points are the significance of this study.

  • The absolute age of lapilli tuff in sedimentary formation that contains dinosaur fossils in the Boseong area, Korea was determined radiometrically against volcanic rocks below and above the fossil-bearing horizons. The sanidine in the lapilli tuff below the fossil-bearing horizon (Seonso formation) has an $^{40}Ar-^{39}Ar$ age of $81.l{\pm}1.4Ma$. The Pilbong tuff above Seonso formation has an $^{40}Ar-^{39}Ar$ age of $81.0{\pm}2.4Ma$. An andesite dyke intruding all sedimentary units yields an $^{40}Ar-^{39}Ar$ age of $42.4{\pm}2.5Ma$. Thus 81 Ma age can be regarded as the best estimate for the age of the Seonso Formation and the associated the dinosaur eggs. This age correlates well with dinosaur fossil finds in the Haenam and Koseong regions of Korea. The occurrence of dinosaur eggs and clutches attests to the existence of dinosaurs in southern Korea at least inCampanian times.

  • A number of dinosaur tracksites located at southern coast of the Korean Peninsula have continuously been damaged by sea-waves and weathering. To protect the dinosaur tracksites from the damage permanently and safely, we need to develop conservation programs as well as to collect data documenting the sites. We specifically applied digital photogrammetry to extensively record and document dinosaur tracks in the Namhae Gain-ri tracksite (Natural Monument No. 499) and were able to obtain 3D images data with it. The data of 3D images enable us to produce permanent documentation and preservation of the morphology of dinosaur tracks and tracksites. Moreover the weathering rate on time can be numerically analyzed by periodic measurements of the dinosaur tracksite and comparison of those measurements. The 3D modeling techniques also can be used in various ways including analyzing morphology of tracks, duplicating replicas for museum exhibitions, and posting the results on the Internet homepage.

  • Animation character market in Korea has been dominated by licensed characters (e.g., Walt Disney′s) of which market share is 80%. While market share for Korean characters such as "Mashimaro" and "Little Dinosaur Dooly" is increasing, the application of such characters to fashion products is still limited. For the development of the Korean character market, application of original animation characters should be applied to various fashion products. The main purpose of this study was to design toddler apparel line using "Little Dinosaur Dooly," one of the most popular domestic animation characters. The design focus is the green color of Dooly because the color is the distinctive concept of the brand. Results of the study indicated that developing toddler apparel line with a Korean animation character was a meaningful attempt, as imported licensed characters were dominant in domestic fashion market. The key differentiating factor was the use of green color. In addition, use of various supporting characters, namely Dooly′s friends, demonstrated potential line extension forming animation character groups similar to Warner Brothers′"Looney Tunes."

  • 20 fossil sites of numerous fossil sites in Korea have been designated as Natural Monument for protection and conservation. Many of the sites which is located at the coastal area have been gradually disfigured by natural weathering, erosion and human activity. Thus the conservation of the original form and the documentation for the original figure are necessary. In this study, we applied 3D digital documentation to Natural Monument No. 394, Haenam Uhangri dinosaur, pterosaur, and bird footprint fossil site, for maintaining the original form of the dinosaur footprints. We were able to obtain the 3D digital data on two dinosaur footprint sites, a high resolution distributional map, and more accurate digital data of the dinosaur footprints applied the rendering method by ambient occlusion. 3D digital data on the dinosaur footprints is worth for the conservation and research data, moreover content for applying to the various fields such as to make 3D brochure, interactive contents, and so on.

  • The Yeosu Sado dinosaur tracksite is well known for many dinosaur tracks and research on the gregarious behavior of dinosaurs. In addition, various geological and geographical heritage sites are distributed on Sado Island. However, educational field trips for students are very limited due to accessibility according to its geological location, time constraints due to tides, and continuous weathering and damage. Therefore, this study aims to generate 3D models and images of dinosaur tracks using the photogrammetric method, which has recently been used in various fields, and then discuss the possibility of using them as paleontological research and educational contents. As a result of checking the obtained 3D images and models, it was possible to confirm the existence of footprints that were not previously discovered or could not represent details by naked eyes or photos. Even previously discovered tracks could possibly present details using 3D images that could not be expressed by photos or interpretive drawings. In addition, the 3D model of dinosaur tracks can be preserved as semi-permanent data, enabling various forms of utilization and preservation. Here we apply 3D printing and mobile augmented reality content using photogrammetric 3D models for a virtual field trip, and these models acquired by photogrammetry can be used in various educational content fields that require 3D models.

  • In this paper, we suggest a lifelike pattern generator for a quadruped walking system with a head, a tail, four legs and a torso. The system looks like a giant dinosaur which stands over 7 meters tall with its legs over 2 meters long. We focus on its lifelike naturalness. Thus, generating logical patterns in harmony with head-body-tail patterns and quadrupedal locomotion patterns makes you feel that the quadruped walking system is alive. The basic patterns of four legs and a body are obtained from a 3D graphic animation, which is made and captured from various motions of similar species in existence since the giant dinosaurs are exterminated. The dinosaur-like mechanism also is designed from bone and joint structures of quadrupedal animals. The lifelike pattern generator based on fuzzy logic could generate lifelike motions according to the dinosaur-like mechanism and the basic patterns. A series of computer simulations and experimental implements show that the pattern generator makes the quadruped walking system lifelike.
