Six sigma is focused on quality improvement through variation reduction, while lean is on process flow improvement and lead time reduction by waste elimination. However, lean cannot bring a process under statistical control and six sigma alone cannot dramatically improve process speed. Lean six sigma was developed to achieve faster rate of improvement in customer satisfaction, cost, quality, process speed, and invested capital. In this paper we present the importance of using value stream mapping and suggest a guideline on how to integrate lean and six sigma by is proposed.

Semiconductor manufacturing is one of the most complex and capital-intensive processes composed of several hundreds of operations. In today’s competitive business environments, it is more important than ever before to manage manufacturing process effectively to achieve better performances in terms of customer satisfaction and productivity than those of competitors. So, many semiconductor manufacturing companies implement advanced planning and scheduling (APS) system as a management tool for the complex semiconductor manufacturing process. In this study, we explain roles of production planning and scheduling in semiconductor manufacturing and principal factors that make the production planning and scheduling more difficult. We describe the APS system implementation project at Korean semiconductor manufacturing company in terms of key issues with realistic samples.

East and West meet in Kenya as tourists to enjoy the climate, hospitality and tourist attractions. Handicraft traders target tourists from the East and the West to buy handicrafts. This research was carried out among textile handicraft traders in open air markets in Nairobi, Kenya to find out their product range, customer base and issues affecting their businesses. The study found that only 25% of the handicraft traders exported abroad. Most of the traders would like to and would benefit more from export trade; however they face challenges in doing so. Handicraft traders are constrained in exporting their products to the East and West because of insufficient information, inadequate capital and lack of contacts in the export location.

Major purposes of this stud? are to analyze Korean firms'innovation networks and sources of knowledge for innovation and to understand their spatial dimensions. In the innovation networks, parent firms are most important for subcontracting firms, while suppliers, customers and competitors are relatively important for independent firms. However, in the future innovation networks, it is expected that government-sponsored research institutions and university wilt become more important on the one hand, networks with foreign firms will become more important on the other hand. Regarding the process of innovation, distance does not matter for the acquisition of codified knowledge. Spatial proximity is, however, critical for the acquisition of tacit knowledge because discussions and researches in a research division within a firm, personal networks of CEO and workers who are responsible for innovation activity, and inter-firm relations with suppliers and customer in a region are regarded important as sources of tacit knowledge. Overall, the innovation networks are different between the Capital Region and non-Capital Region as well as between the industrial complex and non-industrial complex, suggesting that different regional innovation strategies and policies should be established and implemented by considering such regional specificities. Finally, based on the results of this study several policy implications are suggested.

The aim of this research is to examine the tendency of national tastes reflected in global SPA brands based on the theories of Gans' taste culture and Bourdieu's cultural capital. In this study, the leading global SPA brands such as H&M, ZARA, GAP and UNIQLO can be considered as a representative taste culture as well as an icon of popular culture in the $21^{st}$ century global fashion and also the aesthetic taste of each brand differentiated from their national aesthetic values based on socio-cultural backgrounds. H&M represents fashionableness, practicality and environmental friendliness based on naturalism, democratic humanism, and functional practicality of Sweden. ZARA emerges as the most trend oriented brand as well as customer centered on the basis of cultural diversity, passion and glamorous artistic sensibility of Spain. GAP shows American iconic style, which is the functional sports casual wear, originated from American leisure culture and mass production. Lastly, UNIQLO represents high-tech functionalism and practical simplicity based on Japanese delicate workmanship and simple, concise lifestyle while relatively does not much follow the fashion forward trends. Consequently, the national taste has been proved as a solid foundation to identify each global brand. This should be the key component also applied to Korean global brands for developing their concepts and strategies more successfully based on our own national aesthetic taste.

This paper proposes a fuzzy AHP based decision-making model to select a telecommunication company and the target of the proposed model is university students in the capital area. When customers select a telecommunication company, they have difficulty in decision-making because there are many competitive and complementary factors of telecommunication companies. To select a best telecommunication company, customers need to consider a number of different quantitative and qualitative factors such as fare, various services, additional function, etc. In this study, we suggest a fuzzy AHP based decision-making model to select a telecommunication company considering various quantitative and qualitative factors. Especially, fuzzy theory is applied to deal with the unclear or ambiguous problems, and a linear normalization model is developed to convert the value of quantitative factors to fuzzy number. A empirical example which is the target of the university students in the capital area shows the feasibility of the proposed model and it can help customers to make better decision-making for their benefits.

Along with the recent growth of Fintech industry and low interest rate basis, one of the alternative investment technique for expecting higher investment profit, P2P loan using P2P financial system is greatly increasing. P2P loan can be referred to as a type of Crowdfunding that the law of Crowdfunding (adopted to revised Capital Market Act) enacted on January 25th 2016 only allows investment type Crowdfunding so that it can be used as a tool of raising fund for startup and venture companies. Also, it is true that Korean government could not make any legislative foundation related to P2P loan. At this moment, those online platform companies mediating P2P loan are not included as financial companies, expected to cause various legal arguments. Financial Services Commission has released a guideline in February of this year saying that limit of P2P loan is 10 million Korean Won per arbitrating company and 5 million Korean Won per borrower. However, what is more important is to make a law supporting this institutional system. If legislation on P2P loan is implemented without care, it may disturb growth of the field but it may result in the damage of investors if not clearly defined by law. As this is the case, first, "revision of execution regulations for loan business" should take place as soon as possible to intensify inspection of loan companies by registering them to Financial Services Commission. Second, saving customer fund separately in the their organization. Third, making law on protecting investors such as regulating exaggerative advertisement. Fourth, to have transparent and fair public announcement system, standardized agreement and guideline describing clear understanding on autonomous public information publication of P2P loan online platform business and information on the borrower.

Since community growth and vitality frequently depend on local businesses and community inhabitants depend on local retailers for their daily necessities, studying small businesses in rural areas is important to community sustainability. The purpose of our research was to investigate what marketing, merchandising, customer service, or business operation strategies were being implemented by successful independent rural retailers(i.e., clothing, jewelry, floral, hardware etc.), in competition with large discount stores in the U.S.. In addition, social capital as indicated by community involvement was examined for its use as a business strategy that contributes to the success of small retailers. In-depth interviews were conducted with 27 rural retailers representing three communities within a Midwestern state. Data were content analyzed. Participants were following several of the recommended business strategies but opportunities existed to implement changes. Results are discussed in terms of key practices followed by these successful small business owners.
