In recent years, the global geopolitical landscape has been significantly influenced by nations asserting dominance in key sectors, including finance, intellectual property, and military industries. This ascendancy allows states to dictate terms and wield substantial impact on the world order. In particular, China has emerged as a pivotal player, strategically utilizing innovation and economic prowess to reshape international relations. This research examines China’s role in redefining global power dynamics, particularly within Africa, while evaluating the effectiveness and criticisms of its “soft power” strategies. China’s robust presence in critical sectors such as finance, intellectual property, and military industries underscores the correlation between leadership in these domains and global influence. The country’s economic and technological prowess has positioned it as a formidable player, enabling it to exert significant control over international rules and norms. The ramifications of such dominance transcend mere economic power, influencing diplomatic relations and shaping the international order.

As the number of aging nuclear power plants increases, the market for dismantling nuclear power plants is growing rapidly. About 40% of the cost of dismantling nuclear power plants is the waste treatment cost incurred during the dismantling process, of which concrete waste accounts for a significant portion of the total waste. Securing technology for reducing and recycling concrete waste is very important not only in terms of economy but also in terms of environment. The objective is to synthesize geopolymer using inorganic materials from cement fine powder in concrete waste. Cement fine powder in concrete waste has a large amount of inorganic elements necessary for filing materials for radioactive waste treatment such as CaO and SiO2. In particular, Ca(OH)2 is synthesized by extracting Ca2+ from concrete waste. It can be used as an alkali activator to synthesize geopolymer. The mortar from crushed concrete was used as a source of calcium. The first step is to react with concrete waste and hydrochloric acid to extract ions. The second step is to react with NaOH and synthesize Ca(OH)2. The product was divided into two stages according to the reaction method and order. The first and second products were washed and dried, and then XRD and XRF were performed. The second product was matched only Ca(OH)2 and CaCO3 at the XRD peak. In the case of XRF, it was analyzed to have a purity of 67.80–78.73%. Synthesis of geopolymer by recycling materials extracted from concrete waste can reduce disposal costs and improve the utilization rate of disposal sites.

Fashion brands are influenced by multiple identities. Even though, for example, the brand name might still be associated with one or more creative founders (Gucci, Prada, Chanel, Hermès, Adidas, Joop) the brand image, and moreover the overall brand reputation are influenced by many different identities. For instance, a specific product identity (e.g., Gucci’s Bamboo Bag), the identity of the city or country of origin (Florence, Italy), the identities of well-known key customers as brand ambassadors (Sophia Loren, Vanessa Redgrave, Lady Diana, Naomi Watts etc.). Of course, also fashion brands who are not directly associated with the name of creative founders are composed of the effects of several identities. In the case of e.g. Nike especially successful athletes (Steve Prefontaine, Michael Jordan etc.), specific sports and sport events, and product lines tailor-made for them did help to build a strong brand reputation. All in all, it seems to be expedient to understand fashion brands as more of less complex systems composed of several identities. To deal in more detail with such “brand systems” is becoming particularly important against the background of several strategic challenges – e.g., when fashion brands are growing older and the creative founders lose their specific gravitational power, when in the process of internationalization new countries gain more and more importance who’s citizens might not have a strong access to the existing brand reputation drivers, or simply when in the context of the growing global competition the fashion brand needs to be “refreshed”. Against the background of cultural differences, or even - as within countries - lifestyle differences between different groups of customers, it can also be quite possibly that very different reputation drivers account for the success of a brand. Thus, it is necessary to identify, in different contexts, the relevant reputation drivers, and to analyze which interplay of those drivers might be particularly promising. Is it the creative founder, the corporate heritage, the country and/or city of origin, a special designer, a specific corporate culture, an outstanding product design, attractive key customers etc.? Which combination of such identity factors leads to what kind of success (e.g., brand loyalty, brand trust, price premium)? Will, for instance, heritage especially lead to brand trust, whereas an outstanding product design and specifically attractive key customers create the readiness for a higher price premium? And, is it necessary to create sub-brands to especially highlight specific identities in the process of building a brand system (e.g., the sub-branding of a Michael Jordan product line in the case of Nike)? Or is sufficient to only communicate an alignment with the brand (e.g., ads showing Naomi Watts wearing a Gucci Bamboo Handbag)? In other words, which kind of brand system, and which kind of brand communications has to be designed to attract specific target groups and to sustain competitive advantages? The present contribution aims to present a conceptual framework for analyzing “brand systems” in the fashion industry. Concomitantly, an approach of measuring such brand systems will be presented. Furthermore, a concept for analyzing the impact of several sub-identities on the development of the overall brand reputation and brand success against the background of existing contingencies will be outlined. With the introduction and discussion of such a conceptual framework it especially is intended to initiate the launching of an international research project which attempts to find an answer basically to the following question: Which via an integrated branding and brand systems communication carefully crafted composition of sub-identities might be how successful under what kind of situational conditions?

Expanded graphites were used as anode materials of high power Li-ion secondary battery. The expanded graphite was prepared by mixing the graphite with HClO4 as a intercalation agents and KMnO4 as a oxidizing agents. The physical and electrochemical properties of prepared expanded graphites through the variation of process variables such as contents of intercalation agent and oxidizing agent, and heat treatment temperature were analyzed for determination of optimal conditions as the anode of high power Li-ion secondary battery. After examing the electrochemical properties of expanded graphites at the different preparing conditions, the optimal conditions of expanded graphite were selected as 8 wt.% of oxidizing agent, 400 g of intercalation agent for 20 g of natural graphite, and heat treatment at 1000℃. The sample showed the improved charge/discharge characteristics such as 432 mAh/g of initial reversible capacity, 88% of discharge rate capability at 10 C-rate, and 24 mAh/g of charge capacity at 10 C-rate. However, the expanded graphite had the problems of potential plateaus like natural graphite and lower initial efficiency than the natural graphite.

The purposes of this research are investigating the domestic and foreign situations and presenting methods to be able to raise the competitiveness of the power IT industry. For the analysis of domestic situations, 70 companies related with power IT were surveyed. Thus, the problems the power IT industry is now facing are summarized and solutions for them are also suggested. If these solutions are practiced, the power industry could provide higher quality electricity and belong to the prior group of global power society.
