The demand for services using digital technology is constantly increasing as new developments in digital consumer electronics and the Internet are made. This is especially true in terms of the demand for IPTV utilizing high speed Internet networks. Research on IPTV threats is important for facilitating financial transactions via IPTV and preventing illegal use or copying of digital content. Thus, this paper analyzes IPTV threats via the IPTV value chain. That is, the distribution system for IPTV service is analyzed along with the components of the value chain and corresponding IPTV security requirements or security technologies, in order to perform a threat analysis and research suitable for the IPTV service environment. This paper has a greater focus on the value chain of the IPTV business than the approach in previous research, in order to analyze security requirements and technologies that are more applicable to the business environment.

This study investigates how characteristics in the value-chain industrial cluster affect the R&D investment and the output of firms in each industries. For this, we try to extract the inter-industrial networking structure from the input-output table in which 17 manufacturing sectors are included. In particular, we will give shape to the "unit structure" which shows the intermediary flows of goods and services between industries in order to get an unit of final demand in a certain industry. Using this "unit structure", we can try the inter-industrial networking analysis and get some indices of centrality and centralization related to the characteristics of each industries in the value-chain industrial cluster. The results show that the centrality in the value-chain industrial cluster does not have any consequence for the R&D investment and the output in each industries. However, there is a correlation between the centralization in the value-chain industrial cluster and the R&D investment and the output of firms in each industries. These results may be very suggestive in bringing up a new frame of industrial cluster policy in a macro level.

Under the global economic system, production activities has formed an international division of labor, which has greatly affected industries in individual countries by global issues such as the U.S-China trade war and neo-protectionism. In particular the risk and change of disconnection of semiconductor value chain caused by COVID-19 are evaluated as offering the crisis and opportunity at the same time to all countries participating in the global electronics industry value chain. Therefore, this study was conducted with the OECD Trade in Value Added(TiVA) based on the time when a detailed analysis of the global chain of the electronic industry is needed. As a result of the analysis, it was confirmed that the global value chain of the electronics industry is gradually expanding and strengthening, and that various countries are emerging as major actors in the global value chain. It was found that the U.S. and Japan are in charge of relatively high value-added activities, while Korea, Taiwan and China are in charge of low value-added activities, although they are large scale.

Purpose: The purpose of this research is to identify and design a model for the integration between marketing and supply chain management (SCM) of technopreneurship-based souvenirs MSMEs to fulfil customer value creation. Research design, data and methodology: This research method uses the system development life cycle method. This study draws its insights and conclusions from a literature review in several fields followed by an interactive research approach that helps identify, validate, and implement a theoretical framework so that the modelling results can be adopted in applicative manner for souvenir MSMEs. Result: Implementing the "G-ASPOO-L" supply chain management integration model based on technopreneruship to fulfil value creation in the 5.0 society era created three perspectives: an inter-functional perspective, a process perspective, and an integrated business concept perspective. The supply chain management involves enterprise integration, strategic customer integration, strategic supplier integration, and marketing strategy integration. Conclusion: The proposed model framework leads to managerial problems of supply chain management strategy, which urgently requires an interaction approach that challenges the traditional view of demand creation and implementation of supply chain management to fulfil value creation. This research leverages existing knowledge and advances our understanding of the strategic integration issues companies face in digital-based competition.

In recent years, various policies have been conducted for the activation of the value chain for 6th industrialization of agriculture, which is aligned with creating job opportunities and start-up as well as value added enhancement. For this reason, this study seeks measures to kick-start application and development of a model to raise the success rate of startups and reduce the risk of market throughout surveying 168 6th industrialization management bodies about their start-up and business, and benchmarking of best practices, a case consistent with the value chain system of 6th industrialization of agriculture. Main findings are three-folds: First, it is necessary to raise the success rate of startups by means of the compatibility of the capital scale, low cost and life cycle of ideas. Second, the living lab for sharing ideas and collaboration is needed in the value chain system. Third, the living lab model is promoting rural community development and farm household income.

In this paper we consider weak convergence of some rescaled transi-tion probabilities of a real-valued, k-th order (k $\geq$ 1) stationary Markov chain. Under the assumption that the joint distribution of K + 1 consecutive variables belongs to the domain of attraction of a multivariate extreme value distribution, the paper gives a sufficient condition for the weak convergence and characterizes the limiting distribution via the multivariate extreme value distribution.

During the last decade many enterprises spent a huge amount of money for investment on Information Technology (IT) & Information System (IS) to attain competitive advantage and to maximize their business performance by satisfying the various requirements of customers. Under such circumstances, methodologies for evaluating IT impact on business performance are very important issues for strategic decision making on investment. In this study, we propose a performance evaluation model that adopts the concept of the Balanced Scorecard (BSC) and the Value Chain to analyze the financial impact and non-financial impact of IT & IS at each critical work area. This model combines the 4 evaluation areas from BSC and 6 critical work areas from Value Chain and measures the Key Performance Indicator (HPI) and the effect of KPI. Also, we present a case study of which the evaluation model has been conducted on a major manufacturing company. finally. we address some important notes to improve the IT & IS performances in the real-world.

This study was carried out to investigate the micro-agribusiness realities of dairy farms by surveying both farmers' opinions and consumers' recognition of dairy farm products for in a value-chain analysis. In most cases, dairy farms produced fermented milk for sales and to prepare cheese both for sales and for providing the necessary material for farm visitors. Value-chain analysis did not seem to be a viable strategy for dairy farmers, except when assessing the quality of farmstead milk products in comparisons of dairy farm milks and commercial milk products. Consumers had a wide range of experience with milk products and had no willingness to buy products from dairy farms because of the high cost and the lack of product diversity. Our findings established three strategies for improving the economic feasibility of dairy farms. First, the price should be reduced by adopting a production balance to establish a farm-gate price, i.e., not as quota milk but as surplus milk. Second, consumers should be educated on the prescription of cheese at home. Third, a value-chain based on cooperative partnerships should be established among dairy farms. In addition, to improve the consumers' satisfaction on the diversity and quality of farm dairy products, developments of new value-added milk products made from the milk of cows allowed to graze on mountain pastures are needed.

Our agriculture and rural villages have faced negative conditions in many reasons. To overcome this situation, a new change is needed by the 6th industrialization. Many agriculture and rural villages in Korea are pursuing the 6th industrialization through the convergence of the primary, secondary, and tertiary industries to vitalize agriculture and rural villages. But there are several problems with the 6th industrialization. There is a limit to the capacity building of the members of the rural organization and Korean agricultural base primary, secondary, and tertiary industries are weak all. In addition, it has been insufficient research for value chain management of the region as a whole; there has been no study of information sharing across the region for the 6th industrialization. This study is about value chain management model for successful the 6th industry with Quick Response System and the big data technology. In this study to provide the efficiency of 6th industry value chain management with customer's needs analysis using big data and research for the information share between the industries in the region through the information pipeline theory of the QR System. We hope that our study is helped to proceed successfully on the 6th industrialization in Korea.

New product development has been a key element fur organizational evolution. The bulk of research about new product strategy has focused solely on new product development function itself. This paper investigates cross-functional elements in new product development. More specifically, we suggest that there must exist a fit between new product strategy and value chain strategy. It means that, in order to support new product development activity, there must exist a relevant value chain strategy. We consider three types of integration - internal integration, customer integration, and supplier integration - as strategic elements of value chain strategy. For the case of new product strategy, we consider market newness and product technology unfamiliarity as strategic elements. We also consider two types of learning characteristic, i.e., \\\"fast-adaptive learning\\\" and \\\"slow-adaptive leaning\\\" as control factor. Learning characteristic represents firms organizational capability related with organizational learning. For example, fur fast-adaptive learning case, the effect of integration appears early in time. System dynamics simulation is employed to verify our research framework. The results exhibit that there must exist cross-functional relationships between value chain strategy and new product strategy in order to shorten total development time.al development time.
