The effects of flexibilities of supporting structures on shaft alignment are growing as ship sizes are Increasing mainly for container carrier and LNG carrier. But, most of classification societies not only do not suggest any quantitative guidelines about the flexibilities but also do not have shaft alignment design program considering the flexibility of supporting structures. A newly developed program, which is based on innovative shaft alignment technologies including nonlinear elastic multi-support bearing concept and hull deflection database approach, has S basic modules : 1)fully automated finite element generation module, 2) hull deflection database and it's mapping module on bearings, 3) squeezing and oil film pressure calculation module, 4) optimization module and 5) gap & sag calculation module. First module can generate finite element model including shafts, bearings, bearing seats, hull and engine housing without any misalignment of nodes. Hull deflection database module has built-in absolute deflection data for various ship types, sizes and loading conditions and imposes the transformed relative deflection data on shafting system. The squeezing of lining material and oil film pressures, which are relatively solved by Hertz contact theory and built-in hydrodynamic engine, can be calculated and visualized by pressure calculation module.

Service industries nowadays have become the subject of a scientific research. However, unlike research on manufacturing, there has not yet been a broader presentation of important aspects theoretically and methodologically. The importance of service sector in both national and global economies has grown significantly. An active participation of service industries in the internationalization process, notably by licensing and FDI, has occurred over time. But a few sub-sectors still dominate on this process, for example, financial institutions such as banks, securities, and insurance as well as producer services in advertising and accounting. On the other hand, personal services that are owned by small- and medium- sized firm have limited capabilities in their transnational transfer. This paper attempts to examine various factors influencing decisions for these small- and medium- sized Korean beauty firms in entering to the foreign markets. Determining factors for these firms in the engagement of internationalization depends largely on competitive advantages in both domestic and host countries, and they may be different from those in the sub-sectors mentioned above. Based on previous researches, i identified three categories of independent variables(characteristics of firms, managers, and competition) that can influence decisions to enter to the foreign markets. Seven hypotheses have been tested by using a sample of beauty firms in Daegu city and Kyungbuk province. The results show that the intention of these firms to enter to the foreign markets is significantly influenced by the factors of the innovative character of CEO's, the competitiveness of firms, and size of firms.

Loyalty programs are everywhere these days, and among them, coalition programs, where a hub company makes a network of participating companies and users can collect and use points in a large number of participating shops, are in increase. There is little research on the coalition loyalty program. Using the case of OKCashbag, the first and biggest coalition loyalty program in Korea, this study examines whether success factors of single operator program are relevant to coalition programs. This paper contributes first by turning attention to an unexplored area of coalition loyalty programs. By offering an opportunity to reflect on success factors of both single operator and coalition programs, it will help practitioners in loyalty programs to develop innovative loyalty programs using increasingly sophisticated data collection capabilities of IT.

This paper aims to explore the innovation milieu of red-pepper agro-industry in Bonghwa County, in the northern part of Gyeongbuk Province, and suggest policy recommendations for bringing up local agro-industry from a cluster perspective. It turns out that the capabilities of Bonghwa red-pepper agro-industry to innovate are remarkably weak let alone soft infrastructures such as learning networks between innovation agents and social capital. In this sense Bonghwa red-pepper agro-industry can be viewed as an agricultural area simply specialized in production sector rather than a kind of agro-industry cluster. For moving up Bonghwa red pepper industry into an innovative cluster, the paper suggests that the policy makers need to focus on cultivating local learning communities, building a region-wide incorporated brand, promoting the local agricultural technology centre as a network hub of cluster and fostering the functional links between universities and local innovation agents, covering farmers, agricultural organizations, agro-food producers and the local government.

An innovative method for separating overlapping latent fingerprints, using laser-induced plasma spectroscopy (LIPS) combined with multivariate analysis, is reported in the current study. LIPS provides the capabilities of real-time analysis and high-speed scanning, as well as data regarding the chemical components of overlapping fingerprints. These spectra provide valuable chemical information for the forensic classification and reconstruction of overlapping latent fingerprints, by applying appropriate multivariate analysis. This study utilizes principal-component analysis (PCA) and partial-least-squares (PLS) techniques for the basis classification of four types of fingerprints from the LIPS spectra. The proposed method is successfully demonstrated through a classification example of four distinct latent fingerprints, using discrimination such as soft independent modeling of class analogy (SIMCA) and partial-least-squares discriminant analysis (PLS-DA). This demonstration develops an accuracy of more than 85% and is proven to be sufficiently robust. In addition, by laser-scanning analysis at a spatial interval of 125 ㎛, the overlapping fingerprints were separated as two-dimensional forms.
