Three Bacillus strains were isolated from soil samples. Morphological and physiologi­cal characterization indicated that the isolated strains were B. mycoides, B. licheniformis and B. brevis. White pepper was produced from black pepper by the fermentative method using the isolates in shake flaks as well as in a large-scale fermenter. Volatile oil and piperine contents of the product were $3.2\%$ (v/w) and $4\%$ (v/w) respectively. The moisture content was $15\%$. The mi­crobial contamination was less than 10 per 100 g. The product also exhibited excellent storage stability.

Commercially distributed salted and fermented anchovy sauces in Korea were purchased from six different companies. Microbiological, chemical, rheological and sensory analyses were carried out to evaluate the quality and safety and to provide basic information of the products. The salinity of every product was lower than of regulatory standard. All samples tested had acceptable in moisture content and pH. However, wide range of amino nitrogen (AN), volatile basic nitrogen(AN), volatile basic nitrogen (VBN), and trimethylamine (TMA) contents were observed. One product among tested had lower level of AN than regulatory standard. Pathogenic microorganisms were also detected from the samples, therefore sanitation procedure will be needed to ensure safety. From the results, AN, VBN, and viscosity were highly correlated to sensory scores, suggesting that these values can utilized as a standard method to evaluate quality of the salted and fermented anchovy sauce.

Current brand strategies applied for name brand apartments seem to have no product differentiation but merely function as a convenient instrument for product image change through naming only. Since proliferating brand names don't have much relevance to their brand concepts at present, long-range brand strategies are definitely needed. We'll inquire, first, the success and failure cases in the brand strategies of other industry. Next, through questionnaire survey, we'll look into the brand concepts of construction firms and their customer satisfaction. Finally we'll present the necessity of indigenous brand culture by use of macroscopic contents development.

This study aims to propose three universal appropriate conditions, 'difference', 'planning', and 'freshness' for convergence products, and research their contents. 'Difference' means that combined functions have to be all different. 'Planning' indicates that combining different functions has to be proceeded in product development processes, so multiple usages human beings make in their daily lives have to be excepted. 'Freshness' explains that the values of combined functions are expanded by convergence. They are the elements to represent convergence products' functional characteristics and developing processes. They widen the range of convergence products by making in a number of various combining ways, and develop a lot of discourses based among social cultural backgrounds, concepts, and products. This study has shown that convergence is a product method that is managed by strict plans, strategies, and chosen functions. Convergence is a product development method with chosen functions, strict plans, and development strategies. Now, this study will lay the foundation for future works on product development strategies based on convergence.

This study suggests 12 products regarding the pending question of tourism package price mechanism which is linked directly and indirectly to Jeju Tourism, and shows the following conclusions through inspection in mental accounting principles and framing effect based on prospect theory. First, when presenting the price list of the tourism package, it is needed to present in price bundling. Second, it is proven that it is desirable that information about discount prices open the individual discount information of the basic package and option package to public. Third, it is discovered that experienced tourists in purchasing tourism products are more sensitive to price information (price discount) than inexperienced tourists, so that framing effect conform to Knowledge-assembly theory. The current questions of this study are that 'no discount' information should be presented in bundling, that the method of framing is important in presenting discount product information. It is required not only to grasp the viewpoint of modern people in purchasing tourism products, but also to present ready-to-serve products which can save time, effort, cost to give stability in mental accounting principles.

2-dimensional barcode, QR code has been used for containing various information such as image, video, map, and business cards. Currently, a smartphone is used as a QR code scanner, displaying the code and converting it to a standard URL for a website. However, QR codes are not very common in encrypted application and so have a few applications. This paper proposes a new color-code, which integrates the conventional QR code and color design, and can be effectively used in some product certification system. The proposed method exploits the fact that genuine code is produced by CMYK color model, but the counterfeit is captured by RGB color model and during this process, color information of the code is changed. This paper introduces the color matrix model to measure the distortion between genuine code and counterfeit code. By investigating the statistical characteristics of color matrix, an effective detection of print image forgeries are designed. Various experiments with color codes show that the proposed system can be effectively used in product certification systems.
