This study is conducted to verify existing differences in consumer attitude according to distributor type and PB product type. Pre-test was conducted for this study in order to select the distributor and to classify the product type, FGI was conducted with 10 graduate students of K university in Kyong-gi. This study survey housewives, office workers, and university students excluding the participants in the pre-test. In the final analysis, research hypothesis is verified through the data of 280 answers in Korea. This research is conducted with a factor design of 3 types of distributors -department store, discount store, convenience store-and 2 types of product -utilitarian product, hedonic product. To verify the hypotheses, ANOVA is carried out. Reliability test of each measurement variables, Cronbach α coefficient is used. For each analysis, SPSS Windows 15.0 statistical program is used. The findings suggest that First, according to the size and characteristics, distributors are classified into department stores, discount stores, and convenience stores and it is verified whether if there are differences in consumers' attitude (product attitude, brand attitude and purchase intention) by the effect of different distributors. Results showed that product attitude is statistically significant. Second, product type is classified by two categories according to whether the product seeks for practicality or emotional pleasure - Utilitarian product and Hedonic product. In this context, the result after verifying whether if there is difference in the attitudes -product attitude, brand attitude, and purchase intention - in accordance with the product types is shown that utilitarian products makes bigger difference compared to hedonic products. Third, it is confirmed that there is interaction effect between product attitude and purchase intention according to the distributer type and product type. However, we find that in terms of brand attitude, there is no interaction effect. The implications of this research is as the following. First, we propose the need of PB product development and marketing strategy, which considers the product types in accordance with the scale and features of each distributor. Second, PB products should break away from the simplicity of standardized products and consider the different features of distributors. Distributors will be in need of a strategy to build a compelling brand that can differentiate itself from other distributors. This will contribute to the improvement in reliability and formation of product value.

The traditional retail industry significantly changed over the past decade due to the mobile and online technologies. This change has been accompanied by a shift in consumer behavior regarding purchasing patterns. Despite the rise of online shopping, there are still specific categories of products, such as "Processed food" in Mongolia, for which traditional shopping remains the preferred purchase method. To prepare for the inevitable future of retail businesses, firms need to closely analyze the performance of their offline stores to plan their further actions in a new multi-channel environment. Retailers must integrate diverse channels into their operations to stay relevant and adjust to the shifting market. In this research, we have analyzed the performance data such as sales, profit, and amount of sales of offline stores by using clustering approach. From the clustering, we have found the several distinct insights by comparing the circumstances and performance of retail stores. For the certain retail stores, we have proposed three different strategies: a fulfillment hub store between online and offline channels, an experience store to elongate customers' time on the premises, and a merge between two non-related channels that could complement each other to increase traffic based on the store characteristics. With the proposed strategies, it may enhance the user experience and profit at the same time.

This paper develops a new system for remotely monitoring and controlling the windows and doors in mobile environment. We design and implement the opening and shutting unit, the gateway, and the control server system, respectively. The opening and shutting unit consists of the driver using DC motor and the motion controller which monitors the state and transfers the control information. The gateway supports TCP/IP and CDMA protocol, which is the interface of wire and wireless communication for transferring the current state and control information. The control server consists of the program to store and process the control information, the middleware to support the processing of various state message, and DB for monitoring the state and remotely controlling the system. Especially, an application software and the Web-based user interface have also been developed to support the mobile environment. The operation performances, environment influences, driving persistences, and operation failure ratio, which are based on PC and smart-phone, have been tested in 2 authorized agencies. The test results show that the developed system has a superior performance.

Data Mining is widely used to discover knowledge in many fields. Although there are many methods to discover association rule, most of them are based on frequency-based approaches. Therefore it is not appropriate for stream environment. Because the stream environment has a property that event data are generated continuously. it is expensive to store all data. In this paper, we propose a new method to discover association rules based on stream environment. Our new method is using a variable window for extracting data items. Variable windows have variable size according to the gap of same target event. Our method extracts data using COBJ(Count object) calculation method. FPMDSTN(Frequent pattern Mining over Data Stream using Terminal Node) discovers association rules from the extracted data items. Through experiment, our method is more efficient to apply stream environment than conventional methods.

Nowadays, space branding becomes more important since it reflects and synthesizes the diverse experiences of the consumer. The objective of the research is to present the new possibilities that space branding offers by analyzing the brand strategy and the design characteristics of branded hotels, which are being projected as constructed branded environments. By integrating the brand with visible or invisible elements of the hotel, such as unique space planning, service, and consumer experience, a branded hotel can be a good vehicle to reflect fast changing consumer lifestyles and trends; it enables the consumer to experience brands in his or her everyday life, and it conveys the overall image of the brand by considering the consumer's multi-sensual experiences. The study processed with theoretical research which is related to the hotel space and branded environment. Four brands were selected with distinct business area and brand strategy, and studied to analyze the strategy and the characteristics of the branded environment in a branded hotel. In particular, the case study attempted to evaluate the distinctiveness of the branded hotel's spatial design by comparing each brand's representative flagship store with the hotel. As a result, four characteristics of branded environments in branded hotels were identified, namely, strengthen brand image, consistent brand strategy, extend brand perception, spatialize brand experience. Armani emphasizes their consistent brand image by applying similar design methods in both retail stores and hotel spaces. IKEA, in contrast, applies not their design identity but their brand concepts like practicality, efficiency, and low prices. Pantone gives an expanded brand experience by using synesthetic sensual stimulation using their color system. Missoni mixes and composes their patterns and materials in a three-dimensional manner and strengthens design possibilities and spatiality. This study suggests specific design methods to construct a branded environment in a branded hotel and offers new strategic directions for space branding.

In this study, the recovery rate of Tedlar bag (T) sampler was investigated in comparison to polyester aluminum bag (P) sampler. To derive the comparative data sets for the relative performance between different samplers, a series of calibration experiments were performed by using 1 ppb standard of four offensive reduced sulfur compounds (RSC) odorants ($H_2S$, $CH_3SH$, DMS, and DMDS) along with $SO_2$ and $CS_2$. All the analysis was made by gas chromatography/pulsed flame photometric detector (GC/PFPD) combined with air server/thermal desorber (AS/TD). The measurement data were obtained by loading gaseous standards (1 ppb) at 3 injection volumes (250, 500 and 1,000 mL) at three intervals (0, 24 and 72 hrs). The recovery rates (RR) of P sampler were computed against the slope values of T sampler. According to our analysis, P sampler exhibits slightly enhanced loss relative to T, especially with light RSCs ($H_2S$ and $CH_3SH$). At day 0, RR for the two were 88 and 85%, respectively. Such reduction proceeded rather rapidly in the case of $H_2S$ through time. However, P sampler was more stable to store $SO_2$ unlike others. Despite slightly reduced recovery, P sampler appears as a good replacement of T sampler.

In this paper, we propose an algorithm that select efficient relay nodes using information of network environment and nodes. The proposed algorithm can be used changeable weight factors as following network environment in node density. The routing protocols adopting store-carry-forward method are used for solving network problems occurred by unstable end-to-end connection in Delay Tolerant Networks(DTNs). Exiting DTN routing algorithms have problems that large latency and overhead because of deficiency of network informations. The proposed algorithm could be provide a solution this problems using changeable weight factor and prediction of network environment. Thus, selected relay nodes work efficiently in unstable and stressed network environment. Simulation results show that enhancement performance as overhead, delivery ratio, average latency compared to exiting DTN routing algorithm.
