This study investigated solutions of not only weak organization but also poor communication with customers from point of view of SNS such as Naver blog, Naver band, Kakao Talk and Facebook to promote local business market. The study gave strategies: First, SNS marketing strategy shall be used to do public relations and communicate in accordance with features of each SNS. Naver Blog that is opened SNS shall be used to do public relations and to invite new customers, and Kakao Talk that is closed SNS shall be used to increase customers having high loyalty, and Facebook that has both properties of SNS, that is to say, openness and closure, shall be used to raise effects of word-of-mouth to make use of new sales window. The communication can find out customers' needs to provide customers with customized services. Second, Naver Band and/or cafe shall be opened to increase link and friendliness and to have community consciousness realizing common goal and to destroy merchants' helplessness and individualism and to make change of the market for the place of community. Changes among the merchants may get better ideas to do events continuously and to get more SNS marketing effects and synergy. Third, the merchants shall make change not momentarily but continuously by making efforts steadily. Good communication in and out of the market may create inherent brand value to differ from super chain and/or SSM and to increase sales as well as traditional market image and to attain customers' loyalty.

Separation of strontium ion from synthetic seawater in the contained liquid membrane permeator with two micro-porous films was performed. The permeator consisted of a liquid membrane and two cells for aqueous solutions. The liquid membrane consisted of $D_2EHPA(di-2-ethylhexy1-phosphoric acid)$ and DCH18C6 (dicyclohexano-18-crown-6),diluted to 30 vol% with kerosine and was trapped between two micro-porous hydrophilic films. This liquid membrane separated two aqueous solutions, one of which was synthetic seawater and the other of which was the stripping solutions consisting of 1mol/L $H_2SO_4$ solution. The effects of various operating parameters on the extraction rate and equilibrium extraction ratio of strontium ion from synthetic seawater were experimentally examined. The addition of DCH18C6 to the $D_2EHPA$ solution caused synergy effect on the extraction of strontium ion. The permeator extracted strontium ion from synthetic seawater effectively with high membrane life time.

The TOC/DBR and Six Sigma are the most attention-getting concepts for managing manufacturing companies in Korea. Using the ideas and methods of the TOC/DBR, companies can achieve a large reduction of work-in-process and finished-good inventories, significant improvement in scheduling performance, and substantial earnings increase. The Six Sigma approach derives the overall process of selecting the right projects based on their potential to improve performance metrics and selecting/training the right people to get the business results. These two concepts have different backgrounds and different viewpoints for production systems. So, if the two concepts collaborate each other, the synergy effects to innovate production systems can be expected. This paper proposes a new approach to implement the TOC/DBR concepts in production systems. This approach uses some concepts of Six Sigma which stresses educations, project approaches (step by step procedure using a Roadmap), and improvement philosophy.

Digital convergence which means the convergence of industry areas related to digital technologies is an important phenomenon in business, which will decide the fates of firms in the near future. The only firms which can create synergy effects from digital convergence are expected to be the winners in the fierce competition of digital convergence era. In our analysis, we examine the strategy of an integrated firm which has businesses in two different industry areas which are related to each other. By using a game theoretical model, we show how the integrated firm can win over two single separated firms which have business in only one industry area each by leveraging the two businesses the integrated firm has. In our welfare analysis, we also show that this convergence may be even beneficial to consumers, which seems counter-intuitive to social concerns about anti-competitive behaviors by integrated firms. Additionally, we study comparison between industry convergence and product convergence.

The paradigm of the global logistics network has been rapidly changing from traditional concept of productivity in cost terms, toward the new characteristics of innovative productivity in terms of economies of scale, economies of scope, and economies of network. As the ship or airplane becomes larger and speedier, the less logistics hub required. The more diverse logistics parties integrate each other horizontally or vertically, the higher synergy effects they get. The more systematic concurrent engineering available for global supply chain management such as Korean manufacturers in China, the higher productivity they get. The paper analyzes these three paradigms of logistics into the application for the Korean manufacturers in China and concludes that the Korean government, the companies in China should be more focused on the governance of the logistics and the intermediary such as the 4th party logistics(4PL) is definitely developed its role and functions based on three paradigms above mentioned.

This paper empirically examines relationships among corporate strategy, competitive advantage of information technology(CAIT), and organizational performance. Effects of information technology on the linkage between corporate strategy and performance is investigated and CAIT measures suggested by Sethi and King(1994) as well as Sung(1997) are tested for verification. Research results confirm that information technology provides several traits of strategic advantages such as efficiency, threat, functionality, preemptiveness, and synergy and significantly contributes to corporate performance. CAIT measures developed by Sethi and King show strong reliability and validity, Generally, service industry firms show more strong relationship among CAT strategy, and performance than manufacturing industry firms. The findings reinforce the accepted belief that alignment between corporate strategy and CAT is critical for firms to attain sustainable competitive advantage, subsequently enhances corporate performance and competitive position against rivals, potential entrants, substitutes, suppliers, and buyers.

The paper empirically examines relationships among information infrastructure, competitive advantage of information technology, and corporate performance of small and medium manufacturing firms. Effects of competitive advantage of information technology on the linkage between information infrastructure and corporate performance are investigated. The fact that SME's (Small and Mediem-sized Enterprises) are having difficulties in building their own information infrastructure due to the limitation of capital investment, technology, and manpower is the main motive for the study. Research results confirm that information technology provides several traits of strategic advantages such as efficiency, threat, functionality, preemptiveness, and synergy and significantly contributes to corporate performance. But linkage between information infrastructure and competitive advantage of information technology is proved to be weak and this result suggests that systematic and effective information strategy or planning is required to deliver expected advantages of information technology from information infrastructure investments. Also control effect of competitive advantage of information technology on information infrastructure-corporate performance linkage is not strongly recognized.
