Purpose: This study conducted an Importance-Performance Analysis (IPA) of selective attributes of Home Meal Replacement (HMR) as well as it examined the consumers' needs and willingness to buy HMR products to explore the need for developing more HMR products. Methods: This study was conducted among domestic consumers living in Seoul and its metropolitan areas, in the age range from the 20s to the 50s, and who had experience in purchasing HMR products. From the 490 surveys retrieved, 472 (96.3%) valid surveys were analyzed. Results: The analysis of the frequency of consuming HMR products showed the following results: 247 respondents answered '1-3 times a month' (52.3%); 167 respondents stated '1-2 times a week' (35.3%). With respect to the reason of purchase, 'simplicity of the recipe' was the most common, accounting for 188 respondents (39.8%), followed by 'time efficiency' accounting for 172 respondents (36.4%). Analysis of the demand for bibimbap (mixed rice) HMR products showed that 'chicken bibimbap' had the highest preference with 5.32 points, followed by 'bulgogi bibimbap' (5.08 points), and 'kimchi bibimbap' (4.96 points). In the case of HMR products that need to undergo further development, 'low-sodium products' received the highest points of 5.41 points, followed by 'small packaged products' (5.05 points), and 'functional products' (4.98 points). The factor analysis of the 13 selective attributes showed that they can be divided into 3 factors. The IPA analysis of the selective attributes of HMRs showed 'hygiene', 'taste', 'easy to go packaging', 'convenience in intake', and 'accessibility' in the 1st quadrant. In the 2nd quadrant, 'price' and 'freshness' were shown as the factors. In the 3rd quadrant, 'easy to serve', 'familiar food menu', and 'consistent menu' were shown as the leading factors, and in the 4th quadrant, 'saving labor' was the only factor. Conclusion: Based on these results, the research concludes that with respect to developing HMR products, there is a high demand for low sodium, low calorie, small packaged products; thus, showing the need to develop various HMR products for customer satisfaction. Furthermore, it shows that there is a need to consider developing HMR products that can maintain freshness at an affordable price.

Purpose - The purpose of this study is to analyze the efficiency of retail businesses by dividing domestic retailers into discount stores, super supermarkets (SSMs), and department stores. It suggests retail-business investment strategies by using data environment analysis (DEA) to analyze how input elements such as store area, parking lot area, number of employees, and sales management expenses for the convenience of customers positively affect business performance measurements such as sales and visiting customers per day. Research Design, Data, and Methodology - The DEA model calculates a ratio of the weighted mean of various inputs to the weighted mean of various outputs and measures the efficiency of a specific decision making unit (DMU). The study included 19 companies (five discount store DMUs, ten SSM DMUs, and four department store DMUs). Because the business elements and sizes of retail store DMUs used in this analysis are different, average per-store input and output variables were used. Data were collected from "The Yearbook of Retail Industry in Korea (2012)." DEA analysis was used to determine differences in efficiency among discount stores, SSMs, and department stores in terms of the business elements of each retail business. It was also used to determine what business elements were excessively invested in by comparing and analyzing efficiency by business elements using SPSS software's ANOVA (Analysis of Variance). Results - The CCR and BCC efficiency analysis found that the efficiency of discount stores is low. We believe that the saturation state of discount stores is a major factor. The ANOVA analysis confirms the VRS hypothesis with a statistically significant difference among the three groups, based on an analysis confidence interval of 95%. CRS and SE were not found to be significantly different among the three groups. As for the post hoc test, which concretely shows differences by group, the Scheffe's multiple comparison analysis test found the average differences between group 1 (discount stores) and group 2 (SSM) to be statistically significant. Conclusions - The DEA efficiency analysis implies that investment in input elements, including store area, parking lot area, and sales management expenses, were excessive in the case of discount stores, while SSMs need to invest more in promotion activities such as gifts, events, and coupons for customer management. Department stores have found that small companies invest excessively in input elements. Department stores need to invest in differentiated shopping mall complexes. This study was limited in acquiring statistical data; various input variables which might have shown more secure customer management and promotional expenses could not be applied. As the study was limited in various aspects of the efficiency analyses because financial analyses of the companies and of causal relationships, including satisfaction and loyalty of visiting customers, were not done, these aspects will be examined in the next study.

cdma2000 offers several enhancement as compared to TIA/EIA-95, although it remains fully compatible with TIA/EIA-95 systems and allows for a smooth migration from one to the other-Major new capability include:1)connectivity to GSM-MAP in addition to IP and IS-41 networks; 2) new layering with new LAC and MAC architectures for improved service multiplexing and QoS management and efficient use of radio resource ;3) new bands and band widths of operation in support of various operator need and constraints, as well as desire for a smooth and progressive migration to cdma 2000; and 4) flexible channel structure in support of multiple services with various QoS and variable transmission rates at up to 1 Mbps per channel and 2 Mbps per user. Given the phenomenal success of wireless services and desire for higher rate wireless services. improved spectrum efficiency was a major design goal in the elaboration of cdma2000. Major capacity enhancing features include; 1) turbo coding for data transmission: 2)fast forward link power control :3) forward link transmit diversity; 4) support of directive antenna transmission techniques; 5) coherent reverse link structure; and 6) enhanced access channel operation. As users increasingly rely on their cell phone at work and at home for voice and data exchange, the stand-by time and operation-time are essential parameters that can influence customer's satisfaction and service utilization. Another major goal of cdma2000 was therefore to enable manufacturers to further optimize power utilization in the terminal. Major battery life enhancing features include; 1) improved reverse link performance (i.e., reduced transmit power per information bit; 2) new common channel structure and operation ;3) quick paging channel operation; 4) reverse link gated transmission ; and 5) new MAC stated for efficient and ubiquitous idle time idle time operation. this article provides additional details on those enhancements. The intent is not to duplicate the detailed cdma2000 radio access network specification, but rather to provide some background on the new features of cdma2000 and on the qualitative improvements as compared to the TIA/EIA-95 based systems. The article is focused on the physical layer structure and associated procedures. It therefore does not cover the MAC, LAC, radio resource management [1], or any other signaling protocols in any detail. We assume some familiarity with the basic CDMA concepts used in TIA/EIA-95.
