This study testified the influence factors like quantities of advertising, number of hardware and software that are converged, effect on feature fatigue of convergence product. When consumers perceive higher numbers of hardwares in a smart phone, they feel its higher usefulness and complexity. This means that numbers of hardwares is the major factor that enhances consumer's usefulness but, at the same time, it cause perceived leads to higher usefulness in using smart phone, it didn't effect on complexities. It is also important strategy for smart phone companies to provide a lot of useful softwares(applications) to satisfy consumers. Finally, complexity was important factor that lead to higher feature fatigue of consumers. This indicates that smart phone companies have to find adequate numbers of convergence for their new smart phone.

International Courier Service can be used for on campus pick-up and delivery of small items on a pre-arranged basis or on call. Same day service is available for important items at a minimal fee. As e-commerce develops, effective procurement and delivery become even more critical success factors, offering great opportunities to the transportation and logistics Industry in an e-Commerce World. Much of the logistics industry has developed, or is developing systems to operate in the new e-market to capture new electronic tailer clients and enhance relationships with current customers. Supply chain solutions based on EC links will eventually become standard, leaving some companies behind. fresh opportunities and reduced entry barriers to new competitors via e-commerce pose a major threat to the present logistics industry. supply chain systems developers and industry consultants that subcontract physical transport of goods to contractors may encroach on traditional logistics industry business. In this paper I tried to explain various aspects of the physical distribution service through international courier service in an e-commerce world and survey the logistics strategy of international courier service companies against development of electronic commerce based on our companies, logistics strategy.

Recently, the electronic commerce(EC), driven by the development of Internet, has been one of the most important interests. Physical distribution in EC is one of the most important factors. Logistics will be one of the most important industries in the 21st century. Logistics, especially in related to EC presents enormous potential opportunities for logistics Companies. However, logistics companies in Korea still don't have international competitive and effective strategies for customer in compare with leading international logistics companies. So it is needed to study development strategies of logistics companies in Korea against leading international logistics companies. Logistics companies in Korea is able to learn from practical experience of logistics companies in developed country by benchmarking studies. It is three development strategies in order to develop Logistics Companies in Korea. $\circled1$ development of sophisticated logistics service product $\circled2$ reinforcement and enlargement of diverse added service $\circled3$ construction of international logistics network

This study attempts to identify the structure of class conflict in Korea and to suggest an alternative framework for a empathetic society. The objective and subjective level of satisfaction with life and class consciousness are in direct proportion, and status consistency signifies polarization. Distorted distribution structures and cultural values make income disparity and property disputes widen, which in turn lead to educational divides and status fixations, refracting or blocking the possibility of social mobility. By overcoming the COVID-19 crisis, it is not appropriate to go back to the past but to correct wrong consciousness and practices in the past, and the consistency between the state and members of society must be re-established. Through the process of innovation at the economic, global, and digital level, a major transformation is required in the new normal era, which prioritizes social development for human values. The conflict resolution depends on the solidarity of the community as a social foundation, since an empathetic society needs the trust and communication of the members of the society.

This paper presents an architecture for wireless sensor networks (WSNs) with blind source separation (BSS) applied to retrieve the received mixing signals of the sink nodes first. The little-to-no need of prior knowledge about the source signals of the sink nodes in the BSS method is obviously advantageous for WSNs. The optimization problem of the BSS of multiple independent source signals with complex and noncircular distributions from observed sensor nodes is considered and addressed. This paper applies Castella's reference-based scheme to Novey's negentropy-based algorithms, and then proposes a novel fast fixed-point (FastICA) algorithm, defined as the reference-signal negentropy complex FastICA (RSNT-cFastICA) for complex-valued noncircular-distribution source signals. The proposed method for the sink nodes is substantially more efficient than Novey's quasi-Newton algorithm in terms of computational speed under large numbers of samples, can effectively improve the power consumption effeciency of the sink nodes, and is significantly beneficial for WSNs and wireless communication networks (WCNs). The effectiveness and performance of the proposed method are validated and compared with three related BSS algorithms through theoretical analysis and simulations.

The furniture industry of the northern region of Gyeonggi Province consists of several regional complexes which was just autogenously, that is, not based on the organized and planned movements cultivated and clustered, so it stays small businesses. This fact certainly requires to find right courses for future policy direction, in order to develop the furniture industry centering in the northern region of Gyeonggi Province internationally competitive. Consequently the aim of the present study was to investigate the characteristics of the furniture industry in the northern region of Gyeonggi Province first and to present right development directions for the innovation of the structure of furniture industry according to the change of the times, i.e. to connect the industry, university and the authorities concerned well and to strengthen the technology level of furniture industry accordingly. In addition, this requires education and training of the excellent designers being able to create high added-value industrial sectors, including finding a new Korean national brand which should preoccupy the global market. Furthermore, the high-tech furniture industrial complex specialized in manufacture, distribution and marketing such as the division of work between business to business should be built and finally a Korean traditional & unique furniture culture should be created on the basis of a cultural approach of furniture industry. It would be the timing for entire business sectors related to Korea's furniture industry to establish an international standard certification like ISO, in order to upgrade the quality of furniture steadily while keeping our own tradition, and this belongs to a meaningful attempt for the high-tech lifestyles and the improvement in the quality of life of customers.

The relationship between education and work is of the greatest concern to individuals and society because they are the key drivers of growth and development. In the context of Industry 4.0, labor and educators are facing the challenges of big changes in the workplace. How to prepare undergraduate students for the world of employment has become the most important mission of higher education providers. This paper explored the competency gap in the labor market in Vietnam from the perspective of employees who have been dissatisfied with the current status. First, a qualitative method with the Delphi technique was applied to confirm this consensus in an employees' competency model. Then, the satisfaction level for each competency criterion was explored by applying the advance quantitative method, namely, best non-fuzzy performance approach. Lifelong learning was ranked first, followed by creativity and innovation, foreign languages, expertise and digitalization, adaptability, and finally, organizing and managing ability. Critical thinking and problem-solving were perceived to have the biggest gap. The order of competency satisfaction is useful in explaining the mismatch between education quality and labor market demand. The findings provide valuable guidelines for education managers who seek to bridge the competency gap and improve education quality.

This study analyzes the key drivers (commitment, integration of big data, green supply chain management, and green human resource practices) of sustainable capabilities and the influence to which these sustainable capabilities impact the banks' environmental and financial performance. Additionally, this study analyzes the impact of green management practices on the integration of big data technology with operations. The theory of dynamic capability was deployed to propose and empirically test the conceptual model. Data was collected through a self-administrated survey questionnaire from 319 participants employed at 35 banks located in six ASEAN countries. The findings indicate that big data analytics strategies have an impact on internal processes and banks' sustainable and financial performance. This study indicates that banks committed towards proper data monitoring of its clients achieve operational efficiency and sustainability goals. Moreover, our results confirm that banks practising green innovation strategies experience better environmental and economic performance as the employees of these banks have received advance green human resource training. Finally, our study found that internal and external green supply chain management practices have a positive impact on banks' environmental and financial performance, which confirms that ASEAN banks contributing in reduction of environmental impact through its operations will ultimately experience increased financial performance.
