  • The catalytic transformation of sterically bulky tertiary stannane n-Bu3SnH by the Cp2MCl2/Red-Al (M=Ti, Zr, Hf) and M(CO)6 (M=Cr, Mo, W) catalysts yielded two kinds of catenated products: one is a cross-linked polystannane as minor product, and the other is hexabutyldistannane (n-Bu3Sn)2 as major product. The distannane was produced by simple dehydrocoupling of n-Bu3SnH, whereas the cross-linked polystannane could be obtained via redistribution/dehydrocoupling combination process of n-Bu3SnH. The redistribution/dehydrocoupling combination process may initially produce a low-molecular-weight oligostannane with partial backbone Sn-H bonds which could then undergo an extensive cross-linking reaction of backbone Sn-H bonds, resulting in the formation of an insoluble polystannane.

  • An understanding of consumers' evaluative processes and the consumer variables that influence cross-cultural evaluations of foreign products is essential to effectively penetrate international markets. This study compared consumers in two developing countries, Korea and Mexico, regarding their product evaluations and purchase intentions for US Levi's jeans. Both Korean and Mexican consumers are generally quality and price conscious. Korean consumers appeared to be more value-conscious than Mexican consumers. Mexican consumers exhibited high level of brand and prestige conscious behavior. Findings in this study support that culture bound consumer characteristics vary from country to country resulting in differences in perception of quality, value and purchase intentions for a particular product. The perception of product quality differs from perception of value and subsequent willingness to buy. For a comprehensive understanding of consumer purchase behavior, the impact of value-conscious attitude on percetion of quality and on purchase intentions should be examined.

  • The success of new product is a key factor for getting competitive advantages. Marketing research has been investigating marketing capability, manufacturing technical capability, cross-functional integration, market knowledge competence, and competitive environment as the key success factors of new product advantage. Recently, the role of IT capability in enhancing new product advantage is assumed in the literature. However, the empirical studies on the role of IT capability are lacking. The purpose of this study is to identify the effects of IT capability on new product competitive advantages and the relationship between IT capability and the key success factors for new product advantage. Conducting an empirical field study, the IT capability is shown to have a direct effect on new product competitive advantages, and to be also the key success factor to make up for marketing capability and manufacturing technical capability. This study develops a conceptual model on the role of IT capability in enhancing new product competitive advantages by integrating marketing research and IS research.

  • A cross-cultural study was carried out in Germany and in South Korea in order to investigate the relationship between brand personality and product personality facilitating the three dimensions of personality agreeableness, excitement, and extroversion. Two pairs of shoes were prepared across categories of product function symbolic (a pair of high-heeled shoes) versus utilitarian (a pair of sport shoes). In experiments, each pair of shoes was labeled as a luxury brand ("Versace") or a casual brand ("C&A", Germany; "Migliore", South Korea) or left unlabeled. Prior to the experiments, an expert group in each country evaluated the brand personality in terms of "cheerful" (agreeableness), "honest"(conscientiousness), and "provocative" (extroversion) and the results were considered as a baseline. In Experiment I and II, subjects were exposed to two pairs of shoes labeled in one of the three ways and assessed the personality of both pairs of shoes using the personality traits, cheerful, honest, and provocative. Identical versions of the experiment were conveyed in Germany (N=56), an individualist culture, and in South Korea (N=72), a collectivist culture, and we purposed to find cultural differences in evaluating product personalities influenced by brands. The empirical results do not show any significant influence of brand personality on product personality in either cultural group (p>.05). Nevertheless, the subjects estimated the retail price of the shoes to be significantly different depending on the brands in both cultural groups (p<.001).

  • In separating mycelia from antibiotic fermentation broths, high permeate flux was obtained by cross-flow filtration using modified regenerated cellulose membrane. The flux was increased most effectively by increasing the flow rate. There existed a critical mycelium density (about 20% PMV) at which the highest flux was observed. In a batchwise concentration of the fermentation broth, the system suffered from a severe fouling problem, which was relieved drastically by applying diafiltration technique, although it increased the permeate volume. A combined concentration/diafiltration process was ideal in keeping relatively high flux together with a high product recovery yield. The best result was obtained by starting diafiltration after concentrating the broth to 20% PMV. By doing so, a 98% product recovery yield was achieved in the shortest time while keeping the permeate volume at a minimum level.

  • As the media environment surrounding us has changed rapidly, the influences of traditional media decrease whereas promotions using new media have been developing remarkably, Under this circumstance, cross-media advertising, which strategically integrates advertisements on multiple media, is getting attention as an effective marketing communication approach. This study investigated consumer responses to cross-media advertising using both online and offline media, focusing on the effects of product involvement, attributes of media connection, and gender. The experiment was conducted towards adult consumers aged 20 to 39. Results confirmed that the interaction effect between product involvement and attributes of media connection on brand attitude and behavioral intention was significant by a moderating role of gender. Based on the results from this study, both theoretical and practical implications were discussed, as were directions for future research.

  • Tubular construction is widely used in a range of civil and structural engineering applications. To date, the principal product range has comprised square, rectangular and circular hollow sections. However, hot-rolled structural steel elliptical hollow sections have been recently introduced and offer further choice to engineers and architects. Currently though, a lack of fundamental structural performance data and verified structural design guidance is inhibiting uptake. Of fundamental importance to structural metallic design is the concept of cross-section classification. This paper proposes slenderness parameters and a system of cross-section classification limits for elliptical hollow sections, developed on the basis of laboratory tests and numerical simulations. Four classes of cross-sections, namely Class 1 to 4 have been defined with limiting slenderness values. For the special case of elliptical hollow sections with an aspect ratio of unity, consistency with the slenderness limits for circular hollow sections in Eurocode 3 has been achieved. The proposed system of cross-section classification underpins the development of further design guidance for elliptical hollow sections.

  • FEM simulating system of the cross-rolling texture formation offers a systematic and efficient way of exploring the relationship between the process variables and the state of plastic anisotropy of sheet product. Cross-rolled sheets possess higher average plastic strain ratios and lower planer anisotropy than those of the straight-rolled sheets. The employed model is a finite-element polycrystal model which each element used in FEM is assumed to be a crystal having different orientation by Takahashi. Texture development, deformation textures due to cross-rolling are predicted for face-centered cubic sheet metal. Crystal orientations are assigned on the basis of the pole figures obtained by X-ray diffraction. Development of anisotropy during cross rolling of an fcc sheet material is predicted theoretically with respected to flow stress and R-value in tensile test.

  • The neutron induced nuclear data for Mo-95, Tc-99, Ru-101 and Rh-103 was calculated and evaluated in the fast energy region. The energy dependent optical model potential parameters were extracted based on the recent experimental data and applied up to 20 MeV. The s-wave strength function was calculated from the parameters. Spherical optical model, statistical model in equilibrium energy, multistep direct and multistep compound model in pre-equilibrium energy and direct capture model were used in the calculation. The theoretically calculated cross sections were compared with the experimental data and the evaluated files The model- calculated total and capture cross sections were in good agreement with the reference experimental data. The direct capture contribution improved the capture cross sections in pre- equilibrium region. The evaluated cross section results were compiled to ENDF-6 format and will improve the ENDF/B-Vl.
