Understanding the ecological complexity and habitat of a species are crucially important to conserve an endangered species. This study evaluated the patch network ecology of the endangered species $Parnassius$ $bremeri$. The results indicated that 188 individuals were captured and 220 were recaptured, respectively. The sex ratio of female: male was 42:146; males were four times more abundant than females. The average longevity of an adult was $3.93{\pm}3.93$ days (male, $4.0{\pm}3.9$; female, $2.5{\pm}1.0$ days); the maximum longevity was 14 days for males and 13 days for females, respectively. Therefore, the expected longevity of males was longer than that of females. The average emigration distance for the species was 377 m, and the maximum emigration distance was 1550 m. The analysis of patch connectivity and individual colonization revealed that the ideal distance between patches was about 300 m. Moreover, a >600 m patch distance decreased the colonization rate severely. We also observed higher immigration and emigration between patches that were clustered in close proximity. This leads us to conclude that a higher number of patches at a close distance is best suited for $P.bremeri$. We find these results to be crucial to determine a policy to protect and conserve this endangered species.

Purpose: In order to provide the fundamental information for the design development of RGP lenses and its clinical prescription, the corneal types of Korean twenties were analyzed according to corneal shapes, astigmatic degree, and the certain distance from the corneal apex. Methods: Corneal types of total 252 eyes in 20s were firstly classified, then their corneal radii from the certain distance from the corneal apex were measured by corneal topography and further analyzed based on the astigmatic degree. Results: Korean 20s' corneal types were classified as 14.3%(36 eyes) of round, 31.3%(79 eyes) of oval, 28.6%(72 eyes) of symmetric bow tie, 17.5%(44 eyes) of asymmetric bow tie, 8.3%(21 eyes) of irregular shapes. The round and oval typed corneas had mild astigmatic degree whereas the higher astigmatic degree in symmetric and asymmetric bow tie typed corneas were shown. The relative corneal radii of round and oval typed corneas at each distance from corneal apex were shown to consistently increase regardless of astigmatic degrees when they measured at certain distances from the corneal apex. However, the relative corneal radii of symmetric and asymmetric bow tie typed corneas within 1.0-1.5mm from the corneal apex were decreased, which showed steeper slope than it within 1.0 mm and somewhat different based on astigmatic degrees. Bigger change of corneal radii outer 3.5 mm from the corneal apex in symmetric bow tie typed corneas with astigmatism of 1.50-2.00 D and 2.25-2.75 D appeared. Conclusions: The consideration of radial change from the central cornea to peripheral cornea is necessary for manufacturing RGP lens and its prescription since they showed different change in corneal radii by corneal patterns and astigmatic degrees.

Habitat restoration initiative is an important factor for the on-site preservation of butterflies. A new habitat necessitates the investigation of the ecology of the butterfly, the landscape of the habitat, the work process, and a cost analysis. In this study, these factors were analyzed through1) re-consideration of the secured results from three years of field work, and 2) a habitat area estimation conducted according to the presence or absence of larvae and adults via a Parnassius bremeri Bremer survey. The investigation of the natural habitat, done for both larvae and adult butterflies found in South Korea, suggested that multiple patches with a minimum size exceeding $300m^2$ and with an average size of about $1,600m^2$were required for survival of this butterfly. Therefore, more than five patches should be considered for butterfly habitat and patches should have similarity to the present habitat environment with transplantation plans for diet plants and honeydew plants. In addition, to activate the migration of the butterfly, cutting down trees that are obstacles to migration, minimizing the distance between patches and the addition of a stepping patch are also required. A patch connectivity analysis showed that patches should be located within 300m of neighboring patches, as the migration of the butterfly will fail if it is more than 600m. Additionally, more than $10,000m^2$ for a single patch or a patch network composed more than five patches over $1,600m^2$ in size were recommended, with a total patch size of $8,000m^2$. Additionally, neighboring multiple patch networks are more desirable than a single habitat in the event a cyclic habitat pattern arises. In this study, we suggest a habitat restoration and optimal prerequisites for a butterfly habitat. It is expected that this research will lead to the creation of a good model for the restoration of butterfly species.

Cultural commodity is a tourism souvenir for tourists with a high added value in terms of economy. When it excellently represents the region and is based upon its tradition, the positive images of the place can be originated. In this way, the formation of benevolent images has economically considerable effects that can promote the competitive power of the area. The purpose of this study is to develop the pattern design of cultural commodity related to Hampyeong Butterfly Festival. The software to be used is Adobe illustrator CS2, which is a Vector Graphic software, and by utilizing the program, the pattern for the cultural goods will be produced. The forms of the pattern are All over Pattern, which is one of the arrangement methods used the most in a necktie field, and Stripe Pattern. After designing with those two patterns, the design is applied on neckties. Like this, by designing through the Vector Graphic software which we can easily get an access to, the concept of design is visualized; therefore, we can prevent the commodity development that can be conducted out of the concept. By making it possible to visualize the examination by various forms or color mixture, the time is shortened, and throughout reproduction of the object, adjustment of the size, colorway, and reusing or remanufacturing the image, we can check the result of design before hand to reduce the time and expenses required.

The National College of Art. Craft and Design of Sweden founded in 1811 is one of the oldest schools in the world and has taken very important role in the development of Scandinavian design This college usually called "Konstfack" in Sweden was transformed under the influence of Bauhaus into a modern design institute and the experiment:li curriculum and its unique teaching system was completed in the middle of 70' s The phrase "Insight och Flit" in the emblem of this school shows the Konslfack spirit which stresses the creative insight and endless diligence Korea is much different from Sweden in cultural aspects as well as in political and economic ones. In the later half of 19th century Sweden was one of the undeveloped countries in Europe and she just entered the Industrial Hevolution. Swedish culture at the time was also the barbarian one in comparison with English and Frech cultures. Even she had the difficulty in founding her own cultural identity So the Swedish intellectuals in early 20th century tried to find out "What is Swedish\ulcorner" and as the result they produced the Swedish Modern Movement style in 1950's. In this process Konstfack as well as the Swedish Society of Crafts and Design and the Svensk Form. the design magazine. has played the leading role. To look over the history and educational system of this school will be helpful for our design education. will be helpful for our design education.

Purpose: The present study aimed to investigate the effects of corneal eccentricity and shape on the rotational pattern of toric soft lens by the postural change of lens wearers. Methods: The corneal eccentricity of 41 eyes (aged 20s) having -1.0 D with-the-rule corneal astigmatism (WRCA) was measured, and then toric soft lenses were fitted with the amount of total astigmatism. In lying and straight postures, the rotation of toric soft lenses was recorded by a camera attached to slitlamp and analyzed. Results: Most toric soft lens designed with accelerated stabilization rotated to the temporal direction, which was the lying position direction, regardless of corneal eccentricity, and some lenses rotated to the nasal direction for high corneal eccentricity and corneal type of asymmetric bowtie. There was no correlation between the amount of rotation and corneal eccentricity right after of contact lens wearing in straight and lying posture, however, the amount of rotation was the greater for the cornea with the higher eccentricity after the subjects laying down for some period. The speed of lens rotation started to decrease after the subjects laying down, but the speed was not different according to corneal eccentricity difference. The amount of lens rotation for symmetric and asymmetric bowtie-typed corneas increased more than it for oval-typed cornea, and it was same even with time elapsing. The speed of lens rotation in lying posture was the slowest in asymmetric bowtie-typed cornea compared with other corneal types. Conclusions: From the present study, it was revealed that the rotational pattern of toric soft lens was affected by corneal eccentricity and corneal shape when the wearer's posture changed. Thus, it should be considered for the development of the fitting guideline and the design of toric soft lens.

In order to convey exactly what a work is intended to project, it is necessary to select appropriate materials, those whose features are suitable for the work to be accomplished. Among the recent trends in dyeing involve the use of the designers' own techniques and a variety of materials, as well as the designers' efforts at promoting the value of plastic art. According I choose splendid butterfly patterns that diversity in shape and color, among nature patterns offer unlimited imaginative power. I designed the fabric pattern, using tie dyeing, cone dyeing, transfer dyeing and rub dyeing that can best express my intentions. Therefore a total of four works were designed with aesthetically appealing revised shapes of a butterfly, using materials developed using the same method, to suggest the possibility of creating a new design while maintaining the original beauty of plastic art.

Modern clothing is approached in the level of art, and it becomes the means of expressing individuality in modern society uniformed by the development of information society. In this modern society, modern men need the recovery of humanity and expectations of handcrafted skills for the succession of tradition culture. Prior to expressing individuality, we should examine our traditional culture and combine it with western culture. Quit started to be used for practical purpose such as life items, but it is expanded to the fields of art. Used in dress and its ornaments design, quilt is often applied to the addition of aesthetic factors or cubic material feelings by transforming its warming effect. Hereby, this study has a purpose to create high value added modern dross and its ornaments design by expressing the modern clothing is approached in the level of art, and it becomes the means of expressing individuality roe-dimensional characteristics of quilt, and applying the color combination and the surface of butterfly wings to dress and its ornaments design. The following are the results of this study. 1. The concept of quilt started for practical purposes, but it is expanded to decoration in modern times, and it is confirmed that quilt can be variously applied to handcrafted modern design. 2. Quilt removes the plane character of textile and it riches the three-dimensional material of dress and its ornaments. Applying these characteristics, the expression of transparent wings were possible with 3 transparent layers of textile. 3. The spledid color of butterfly wings are expressed by coloring oganza and felt, and the various colors of felt showed rich color gradation. 4. The form and pattern of butterfly wings are applied as modeling form and line, and the transformation. repetition and expansion of unit forms determined the form of quilting lines. By designing the characteristics of back wings for the composition line of clothing, the form characteristics of a motif could be emphasized. 5. By using felt, oganza, Damdam yarn and ostritch feathers in expressing butterfly wings, the warm material of Linbun is felt, and the tip hair of wings are expressed by croche techniques using Damdam yarn.
