This study analyzed the most frequently used navigation cases in a desktop environment. As a result of the research, GNB induces users' search as the top element of the search structure and can place color, text, icon, and image elements. LNB could be classified in the form of a dropdown, flyout, dropline and mega menu. In this study, the navigation structure of Interpark and Interpark among open markets used by users was analyzed. G-Market's GNB has a two-tier structure with color, text, image, and icon elements, and Interpark has a three-tiered horizontal label. Interpark's GNB drew attention by placing a badge on the seasonal label, which is a temporary content section, unlike G-market. It can be seen that the LNBs of both shopping malls have flyout menus that protrude when you mouse over the category menu arranged in a vertical text form under the logo placed on the left. The flyout menu has a complex structure consisting of the layout of the mega menu. This study is meaningful in revealing user experience elements by analyzing the GNB and LNB of shopping malls these days where internet shopping is increasing.

This paper outlines the current steel design climate and describes some recent and unusual designs using structural steel or composite steel and concrete which have been carried out in Hong Kong and the East Asia region. Composite structural systems for very tall buildings are outlined. A case study of concept designs for one of these is presented. Two further case studies are presented: a refurbishment project where the use of steel and innovative strengthening techniques allowed an additional five stories to be built on an existing reinforced concrete frame and a monumental sculpture.

Recently, because of mega foundations and grand bridges, the foundations require significant bearing capacity. In this study, bearing capacity of high strength steel pipe pile with an extended head (HSP) is calculated on the basis of domestic criteria and Japanese criteria. And bearing capacity of HSP is investigated based on 3 field tests. In comparison with the results of analysis and tests, it is shown that the field test results are bigger than analysis results. Therefore, it is proposed to estimate bearing capacity of HSP.

신재생 에너지 분야에 적용되는 계통 연계형 인버터에서는 출력 전류 리플을 감소시키기 위하여 필터 인덕터가 필수적으로 사용된다. 현재 출력 인덕터로 적용될 수 있는 코아 재질로는 실리콘 함량이 2%정도인 일반 철심과 6.5% 정도인 슈퍼코아(Si 6.5%)와 Mega Flux 코아 정도가 있다. 본 논문에서는 각 코아별 특성을 살펴보고 인덕터 코아 특성 변화가 인버터의 효율 및 출력 전류의 THD에 미치는 영향을 인덕터의 값과 스위칭 주파수에 대해서 분석하였다. 또한 현재 시장에서 수요가 많은 10kW 태양광 인버터를 통하여 최적의 인덕터 설계에 대해 제시하고자 한다.

This study considers the local players in the European steel industry, whose the amounts of crude production are more or less 5 million tons per annum. They do not belong to the Pan-EU mega-group of steel mills with more than 15 million tons of crude production yearly. However, these mid-sized steel mills in European countries have been originated from the strong foundation of steel, scientifically and technically, as well as the centennial history. They concentrate on the niche market adjacent to the local area, which takes advantage of the geographical location. The companies considered here are VoestAlpine in Austria, Salzgitter in Germany, Rautaruukki in finland, and SSAB in Sweden. Their corporate strategies are compared on the basis of product mix and sales structure. And, the deep analysis for each company is performed, such as business strategies with the sales volumes, market strategies. competitiveness improvement planning. and R&D policies with the technology management. These analysis results can be benchmarked as the cases of best practices for domestic steel mills, especially mid & small sized companies, that develop business and market strategies for the sustainable growth and profitability.

Objectives : This study was performed to determine if unknown species of antler samples could be identified by genetic distance methods. Methods : The DNAs of 4 antler samples were extracted, amplified by PCR, and sequenced. The DNAs of antlers were identified by genetic distance. Genetic distance method was made using MEGA software (Molecular Evolutionary Genetics Analysis, 3.1). Results : By genetic distance methods, all 4 antler samples were closest to Cervus elaphus nelsoni among Cervus species. Conclusion : These results suggest that genetic distance methods might be used as a tool for the identification of Cervus species.

Measurement of the phosphorus concentration in aerosols in Beijing, which was a representative East Asian mega-city, was carried out. The optimum procedure for analyzing phosphorus in aerosols was found in this study. Recovery of phosphorus in environmental samples through the improved method was almost 100%. The concentration of phosphorus in TSP was $145{\pm}47\;ng/m^3$, with a seasonal variation showing high concentrations in winter and low concentrations in summer. The concentrations of phosphorus in $PM_{2.5}$ accounted for $35{\pm}6%$ of those in TSP, with no seasonal variations. The major source of phosphorus in aerosols in Beijing was soil dust, and additional sources of phosphorus in fine particles could be coal combustion and biomass burning.

The raccoon dog (Nyctereutes procyonoides) may be infected by Dirofilaria immitis. However, there has been no report on dirofilarial infection in the raccoon dog in Korea. In this study, we report on D. immitis infection in two wild raccoon dogs captured in the Daejeon area. The two raccoon dogs were referred to the Veterinary Teaching Hospital, Chungnam National University for diagnosis of D. immitis infection. The modified Knott's test for the detection of blood D. immitis microfilariae was positive, and serological test (FASTest$^{(R)}$ HW Antigen ELISA kit, Diagnostik Mega Cor, Austria) for D. immitis was positive as well. Additionally, D. immitis microfilariae were differentiated from other microfilariae by using acid phrnphatase histochemical staining (Leucognost-SP$^{(R)}$kit, Diagncstica MERCK, Germany). The two raccoon dogs were necropsed and D. immitis infection was confirmed.

As mega-sized and complex building construction projects are increased, the importance of project scheduling and control is emphasized. Project scheduling and control technic is not used widely yet in Korea, but interests in it is progressively increased. By now, most research projects mainly have focused on scheduling issues. Project progress management is also as much important as project scheduling issues. Current state about project progress management in Korea is analysed and way for improvements are suggested in this paper. At first, research projects undergone and practice are analysed and fields experts are survey about current state about project progress management. This study suggests the progress management method for quantitative and qualitative project progress analysis.

For the successful characterization of the fractured reservoir, it is inevitable to describe fracture properties more precisely. Although the deterministic features, of mega-trend faults can be relatively definite, the background features of minor fractures are not easily analysed in spite of the various data of these features. In this study, two different methods, statistical and fractal methods, are used to construct the minor fracture system over the entire field. After completing these tasks, with the identified deterministic features and background features, total fracture system for fractured reservoir is constructed and updated with the aid of dynamic data obtained from well test.
