  • This proposal is to present a campus landscape plan for PaiChai University. The site is located in 439-6 Doma-dong, Seo-gu, Taejon City and has an area of $208,499m^2$. The landscape plan covers the following: site inventory and analysis; integration of design program and site analysis; evaluation of design concept; schematic design including circulation form and spatial form; and design development including subarea design. In the design process, the author focused on the integration and interpretation of site conditions as related to the university buildings. He also collectively analyzed and considered the physical development of the outdoor spaces of Paichai University. The following are some of the major areas in the design of the outdoor spaces of Paichai University: 1) a main entrance space as a symbolic square, 2) Paichai central street, 3) a campus core as a greenish square, and 4) a 'Jajuro' plaza as Paichai 'Han' square. The outdoor spaces of Paichai university are created as a new type of campus realm with function, campus quality, original identity, symbolic meaning and images and beauty.

  • Dendrophyllia compressa Ogawa and Takahashi, 1995 is newly reported from Korea. The specimen was collected off Seogwipo, Jeju-do, Korea in 1969. It is described herein based on the morphological characters of the skeletal structures. Dendrophyllia compressa is characterized by its small and bushy growth form with branches, vertical growth direction, small calicular diameter, compressed calice, Pourtalès Plan with vertical septal inner edges, flat and spongy columella, exserted septal upper margins, and epitheca. Dendrophyllia compressa has been synonymized with Cladopsammia eguchii . However, the former species differs from the latter species in its growth form, growth direction, colony size, corallite size, and corallite shape.

  • This paper presents the pillar section optimization technique considering the reliability of the vehicle body structure consisted of complicated thin-walled panels. The response surface method is utilized to obtain the response surface models that describe the approximate performance functions representing the system characteristics on the section properties of the pillar and on the mass and the natural frequencies of the vehicle B.I.W. The reliability-based design optimization on the pillar sections Is performed and compared with the conventional deterministic optimization. The FORM is applied for the reliability analysis of the vehicle body structure. The developed optimization system is applied to the pillar section design considering the fundamental natural frequencies of passenger car body structure. By applying the proposed RBDO technique, it can be possible to optimize the pillar sections considering the reliability that engineers require.

  • This study is used to analyze the distribution of resistance factors and the relationships of flow resistance with the field measurements which consist of the total 2,604 rivers for 1,865 bed material in natural channels and 739 vegetation in vegetated channels. Resistance factor relationships and distribution range of Manning roughness coefficients and Darcy-Weisbach friction coefficients by the regression analysis are derived from the power law form as a function of flow discharge and friction slope with bed materials and vegetations in natural and vegetated rivers, respectively.

  • Due to high esthetic demands from patients, we are driven to fabricate natural-looking(form and color) restorations. In the past decade, the glass-ceramic in dentistry has been used as a material with variable crystals that affects the appearance, characteristics, and mechanical properties of metal-free fixed restoration. The conventional IPS Empress glass-ceramic is a heat-pressed, leucite reinforced material using the "lost wax" principle. This glass-ceramic has been successfully used for esthetic restorations such as all-ceramic crowns, inlays/onlays, and veneers for about 15 years. This article presents that the form and surface texture of clinical crown are duplicated by IPS-Empress system using "lost-wax technique".

  • A taxonomic study on marine sponges was conducted by SCUBA diving at Gageodo Island, Korea from August 1999 to July 2001. Among them, Haliclona (Gellius) coreana n. sp. turned out to be new to science. This new species seems to be close to H. (G.) arcoferus Vosmaer, 1885, based on the type of spicules. However, it is different in size of toxa and growth form. Toxa of the new species is half in length compared to H. (G.) arcoferus. The growth form is jar shaped in this new species, but flat in H. (G.) arcoferus.

  • Dome structure to form a space-efficient, applied a lot of beautiful buildings with structural systems, as well as a large space structure in the form of new residential lots have been applied. And domestic demand for housing in the dome with increasing dome house using various materials, are becoming commonplace. But now the Dome House is mainly used in construction steel, wood, stone, FRP construction and building materials per unit area and the high cost, long construction time, energy efficiency, has some disadvantages such as degradation. And structural strength of the structure is weak, the natural ingredients used come from natural damage is so big. In addition, demolition of buildings in trouble when handling the environmental problems has emerged. Recently expanded polystyrene to improve these problems by using the various approaches and research is being attempted and there.

  • The two zooxanthellate scleractinian corals are newly recorded in Korea: Psammocora albopicta Benzoni, 2006 of the family Psammocoridae and Oulastrea crispata (Lamarck, 1816) of the family Faviidae. These families are also newly recorded in Korea. Specimens were collected from the subtidal zones of Jeju-do Island, Korea by SCUBA diving from 1999 to 2014. Two scleractinians are described based on the morphological characters of skeletal structures. Psammocora albopicta is distinguished by its encrusting cerioid growth form, high density of corallites, small calicular diameter, single styliform columella, and fewer rows of enclosed septa. Oulastrea crispata is characterized by its encrusting plocoid growth form, polygonal calicular shape, irregular paliform lobes, and papillose columella.

  • In this study, the characteristics of headwear design by John Galliano's collections had been placed under the interpreting the immanent characteristics of presented in external things. His headwear design was found to have following characteristics; ethnic forms, historical forms, natural modeling forms, artifical forms, false hair forms and abstract forms. And his headwear design was found to have folling immanent characteristics; expaned exaggeration, introduced into existing form and reconstruction, mixed with different motives, change of texture, introducing and parody by natural and artifical form, pure abstacted construction. Furthermore, it can be identified that immanent characteristics and external things are mutually linked.

  • The germinatin of e. annuus continued from the middle ofmay to mid-october. The maximum germination occurred on the mid-july. The period bloom of was distingushed amongs the different growth forms ; a orm pr of biennial and a form of pr perennial flowering from the mid-may to mid-september, and a form ps biennial blossom from the beginning of October to earlynovember. the dispersal of seed for(a form pr)occurred from early June to the mid-september. A rotte, germinating from summer to autumn, could classified into several growth forms; individuals without a critical leaf area for bolting until september and October, become a form ps of biennial, whicth did not proceed toreproductive growth unitl the next year, even thought wintering. individuals flowered on 3 years after germination become a form pr of perennial. The growth formular of aform pr of bennial, grown in a pot was w=20.2[1+$3.36{\times}10^3$(-0.062t)]$^{-1}$. The maximum relative growth rate(rgr) was 0.062g/g/day and the maximum net assimlation rate(nar) 0.089g/g/day. Therelative growth among each organ was shown as R=0.12 $T^{1.15}$between the avove-ground part(t) and the below- ground part(r). the relation between the avove-ground part(t) and the ratio of stem weight(wi) was ws/wi=2.56 $T^{0.35}$. n.p.k. was largely distributed on a leaf throughoutthe total growth period. while growing, it tended to decrease on the vegetative organ gut vice versa on the reproductive organ. however, nitrogen was more widely distributed on a leaf then in the reproductive organ.
