Despite the SKM Duyree shop's potentials, such as residing over the Samsung-dong, gangnam-gu one of the premier locations in Seoul, and offering a large shopping store, the old 'SKM Dutyfree' symbol [image #2] has become the burden for a company due to its low-profile brand quality and lack of location advertisements. Therefore, first, we have agreed to acquire the popular brand word 'COEX' and replace "SKM Dutyfree" to "COEX Dutyfree", and second, the new visual image has been created in order to create a synergy of the urban-look and the location-information. Therefore, the visual identity design concepts have been utilized in order to achieve such goals; first, promote the existing COEX-image and metropolitan-esque image. Second, unify the international-metropolitan looks of the COEX-mall, hotel, shopping center, exhibition, and airport terminal with location information. Third, deliver the new identity-design [image #1] of the fresh look(compare to competing dutyfree shops) and dynamic images.

In this study, Sangpyeontongbo excavated at Bigyeongdo, Seosan, were investigated to determine the components of the corrosion products that were formed while they were buried underwater in an anaerobic environment. The causes of corrosion product formation were also determined. Microstructure observation, element mapping, principle component analysis for each year, and the detection of corrosion products were carried out. Results indicate that the concretions of corrosion products on the surface are needle-, hexahedral-, and octahedral-shaped; Pb, Cu, and S were among the elements detected. The Cu-S layer was clearly verified using element mapping. An analysis of major elements for each layer showed that Cu, S, and Pb were present and that most Zn was eliminated. The corrosion products detected were $PbCO_3$ (concretion) and $Cu_{1.96}S$ (metal). Accordingly, the anaerobic corrosion properties of Sangpyeongtongbo are summarized as follows: dezincification, copper sulfide, and lead compound.

High performance permanent magnets have become the subject of considerable attention because of the potential applications in the traction motors of hybrid and electric vehicles and wind generators. Nd-Fe-B magnets have attracted considerable interest due to a large maximum energy product. However, Nd-Fe-B magnet cannot be used in high temperature (${\sim}200^{\circ}C$) applications due to the thermal degradation of coercivity. Therefore, the development of high coercivity Nd-Fe-B permanent magnet is a challenging issue. In case of high coercivity Nd-Fe-B permanent magnet, an increment in the intrinsic coercivity can be easily achieved by substituting Nd atoms with Dy or Tb atoms. However, these heavy rare-earth elements are known to cause a decrease in remanence due to the antiferromagnetic coupling between Dy and Fe atoms. In addition, Dy is relatively expensive and being limited in quantity. Hence, a new technology that can increase the coercivity of Nd-Fe-B sintered magnet using only a small amount, or even, no amount of heavy rare-earth elements is being investigated. This article describes the research trend in reducing the heavy rare-earth elements in Nd-Fe-B magnets.

This research was carried out to promote the seed germination of Styrax japonica, by several pretreatments and to examine its seedling growth and seed component variations according to time and pretreatment. The results are as follows ; 1. Styrax japonica seeds are usually germinated after more than one year cold stratification. However, when the seeds were stratificated for 5 months after dipped in the solution of 70% $H_2SO_4$ for 30 minutes and also treated with $GA_3$(3000ppm), they showed 55% germination. This demonstrated that the seeds could be germinated in one year when pretreated. 2. The growth of one-year-old seedlings after pretreatment was the same as that of two-year-old seedlings when compared 160 days after seeding. 3. Before seeding, one-year-old, pretreated seeds of Styrax japonica showed increased moisture content but decreased crude fat, carbohydrate and exude ash, which were similar to the components of two-year-old seeds.
