A three-arm parallel design has been proposed to assess the biosimilarity between a biological product and a reference product using relative distance (Kang and Chow, 2013). The three-arm parallel design consists of two arms for the reference product and one arm for the biosimilar product. This paper extended the three-arm parallel design to a (k + 1)-arm parallel design composed of k (${\geq}3$) arms for the reference product and one arm for the biosimilar product. A new relative distance was defined based on Euclidean distance; consequently, a corresponding test procedure was developed based on asymptotic distribution. Type I error rates and powers were investigated both theoretically and empirically.

Using of QR(Quick Response) code is dramatically extended to various marketing area; not only substitute of bar code but also new tool of PR and marketing. This research attempts to analyze brand communication effect using QR code printed on product package especially in snack product category. Findings are 1) communication effect are different according to the type of book-trailers; 2) cinematic production and animation are the most effective type of book-trailers; 3) for memory and confirmation(sharing), a)stills and straplines, Analysis result of hypothesis I showed that characters of QR code influence on brand attitude. Among dependent variables, only reliability is significant. That means reliability of company and brand using QR code influence on brand attitude. The higher reliability of QR code, the better brand attitude of the brand. Analysis result of hypothesis II found that only reliability is significant on purchasing intention. Reliability of company and product using QR code influences on purchasing intention. The higher reliability of QR code, the higher possibility of purchasing products. Therefore, company can enhance reliability of both company and its products by using QR code. Using QR code will bring high reliability and high brand attitude and purchasing intention.

In this study, we investigate the relative effectiveness of the two types of brand extensions (sequential extensions vs. direct extensions) in dissimilar extensions and examine the moderating role of two key variables - brand concept(functional brand vs. symbolic brand) and price of target extension product(low vs. high). The results from two experiments show that consumers evaluate the target extension product more favorably when brand is extended sequentially to dissimilar categories than when it is extended directly. However, the difference of target extension product evaluation between sequential extensions and direct extensions decrease when brand is symbolic and price of target extension product is high. Theoretical and managerial implications of the finding are discussed and inplications for future research are suggested.

Jung et al.(2015) suggest the two-phase warranty model, which is a general type of warranty model. Under the two-phase warranty, the warranty period is divided into two intervals, one of which is for renewing replacement warranty, and the other is for minimal repair warranty. And warranty policies play a very important role in product marketing. In this paper, we suggest the optimal warranty policy for free extended two-phase warranty. To determine the optimal warranty period, we adopt the expected profit per unit product. So, the expressions for the total expected cost, the sale price and the expected profit per unit product from the manufacturer's point of view are derived. Also, we discuss the optimal warranty period and the numerical examples are provided to illustrate the proposed the warranty policy.

Despite the attention regarding the effects of brand extension, there is limited research focused on brand extension in the beauty industry. This study discusses whether the similarity of extensional types and brand fit has any effect on the brand attitude toward beauty brand extension. This study examines the changes in the brand attitude and finds the effect of the similarity of extensional types and brand fits on brand attitude toward beauty brand extension. In the experiment, 4 description type factorial designs were performed. A total of 114 females participated in the experiment that had an experience of visiting a beauty salon. The results are as follows. First, the similarity of an extensional product-type has a positive effect on attitude toward parent beauty brand, while the similarity of extensional service-type does not. Second, there are significant independent and interaction effects between similarity and brand fit, which reveal differential influences on attitudes toward an extended beauty brand. Attitudes toward parent and extended beauty brands were affected by the similarity of extensional types and brand fit.

Software product line engineering is an approach to creating core assets by systematically exploits common that can be highly reusableand different characteristics in related system families that is domain. By adapting this approachin object and component paradigm, software productivity is extended. Recently, Software development paradigm is changed to service oriented paradigm which is using services that are core assets. Therefore, to develop service oriented software more flexible, systematic and to enhance business agility about business changes, we need adaptation of product line to creation of services that are core assets. In this paper, we propose an approach to create and specify domain service through combine of product line and service oriented paradigm. Domain service explicitly specifies commonality and variability by domain service common/optional property variability, operation type variability, message type variability. By using this approach, it can support efficient and flexible service oriented development by producing various services through customization of domain service for the purpose.

This study was to analyze the trademarks of The Polo Lauren Company in fashion products and its analogous trademarks that have been applied or registered in the Korean Patent Office. The data was collected from the Korean Patent Office and KIPRIS search system was used. Total 468 trademarks applied by the date of September 10, 2003 including 317 registered trademarks of the Polo Lauren Company and 151 its analogous trademarks applied for fashion products, were used for the analysis. The results were follows. (1) Total 73 different types of trademarks of the Polo Lauren Company were registered for 26 product classification. Trademarks were composed of all possible combination of letter, sign and sketch to prevent the registration of its analogous trademark. Also even the same trademarks were registered for each different product classification. Since the early 1990s the extended trademarks for each segments reflecting diverse lifestyles were frequently registered. (2) Total 134 trademarks that had applied for registration were rejected due to its analogousness to the Polo Lauren. Most of them were seem to purposely analogous to mislead and to confuse consumers. The major type was to add one or two words as brand extention to the genuine Polo brand. Next type was minor modification of genuine trademark. The last type was almost same brand names in different product categories. (3) Total 3 trademarks were not permit to register by the objection of the Polo Lauren Company. Total 19 trademarks were permit to register. Those showed low degree of analogousness. However most of these trademarks were cancelled by the lawsuit of the Polo Lauren company.

This paper is dedicated to studying some Hausdorff operators on the Heisenberg group ${\mathbb{H}}^n$. The sharp bounds on the strong-type weighted Lorentz spaces ${\Lambda}^p_u(w)$ and the weak-type weighted Lorentz spaces ${\Lambda}^{p,{\infty}}_u(w)$ are investigated. Especially, the results cover the classical power weighted space $L^{p,q}_{\alpha}$. The results are also extended to the product spaces ${\Lambda}^{p_1}_{u_1}(w_1){\times}{\Lambda}^{p_2}_{u_2}(w_2)$, especially for $L^{p_1,q_1}_{{\alpha}_1}{\times}L^{p_2,q_2}_{{\alpha}_2}$. Our proofs are quite different from those in previous documents since the duality principle, and some well-known inequalities concerning the weights are adopted. The results recover the existing results as well as we obtain new results in the new and old settings.

Numerous products are on the market every day and consumption is becoming increasingly polarized. Some products have been introduced to the market for the first time and others are the existing products that have upgraded performance. For companies, new products must be released constantly to prevent losing existing customers and to increase loyalty. However, when companies released new product, they communicate consumer brand name and core benefits of the new product. Moreover, if a new product fails, the amount that the company has to pay is bound to grow. So companies often use brand extension strategies that use the names of famous brands that are already loved by their customers for new products. In this study, the effect of extension similarity, time of release, and message type on brand extension was investigated. Result shows that using abstract messages rather than specific messages is more effective when similarities with existing brands are poor. In particular, the closer the release period is, the more effective these effects are. However, in case of extending the brand with high similarity products, it is effective to focus on concrete messages when the release time is near, and to communicate abstract messages when the release time is long. This result suggests that companies should take into consideration not only the similarity of extension but also the timing and characteristics of messages when extending the brand.

In this paper, we analyze a logistic system involving a supplier who produces and delivers multiple types of items and a buyer who receives and sells the products to end customers. The buyer controls the inventory level by replenishing each product item up to a given order-up-to-level to cope with stochastic demand of end customers. In response to the buyer's order, the supplier produces or outsources the ordered item and delivers them at the start of each period. For the system described above, a mathematical model for a single type of item was developed from the buyer's perspective. Based on the model, an efficient method to find the cycle length and safety factor which correspond to a local minimum solution is proposed. This single product model was extended to cover a multiple item situation. From the model, algorithms to decide the base cycle length and order interval of each item were proposed. The results of the computational experiment show that the algorithms were able to determine the global optimum solution for all tested cases within a reasonable amount of time.
