This study aimed to identify the characteristics of Home Meal Replacement (HMR) product purchases and the need for HMR product development for Hong Kong consumers in order to suggest market segmentation strategies according to consumers' dietary lifestyle. For this, an online survey was conducted on a panel of 521 Hong Kong consumers with HMR purchase experience registered at a specialized organization. Data analysis was performed using SPSS (ver. 23.0). HMR purchase characteristics of Hong Kong consumers according to dietary lifestyle showed significant differences in all items, including 'number of purchases', 'purchase location', 'cost of single purchase', and 'reason for purchase'. According to dietary lifestyle, participants were divided into three clusters: 'High interest', 'normal interest', and 'low interest'. In the case of 'high interest in dietary life group', 'low-sodium food' was the most common, followed by 'heating food', 'low sugar food', and 'low calorie food'. In the case of 'moderate interest in dietary life group', 'low-sodium food' was the most common, followed by 'low sugar food', 'low calorie food', and 'nutritious meal'. In the case of 'low interest in dietary life group', 'low sugar food' was the most common, followed by 'low-sodium food', 'various new menu', and 'easy-to-carry dehydrated food'. For the 'high interest' group, the highest proportion of consumers were male in between the ages of 20 to 29, married, and worked in an office job. The 'high interest' consumers also showed a tendency to pay '15,000 to 20,000 KRW' per single purchase. The 'normal interest' group consisted of an even proportion of male and female consumers, with the most common age range being from 30 to 39 years, and most were married. These consumers preferred to spend 'less than 10,000 KRW' or '10,000 KRW to 15,000 KRW' per single purchase, which is in the lower price range for HMR purchases. The 'low interest in dietary life group' had more females gender-wise, were unmarried, and worked in an office job, For a single purchase, the 'low interest' group chose to pay less than 10,000 KRW, which is relatively lower than the other two clusters. The results of this study can be used as baseline data for building marketing strategies for HMR product development. It can also provide basic data and directions for new HMR export products that reflect consumer needs in order to create a market segmentation strategy for industrial applications.

This study examined how consumer choices (i.e., selecting food safety certified products, health-related products, and familiar brands) affect the purchase of Korean native chicken (KNC) and the demographics that influence KNC purchases using secondary consumer panel data from the Rural Development Administration of Korea. The grocery purchase data from 654 Korean households between 2017 and 2019 were used; the propensity for food safety certified products was measured by the purchasing frequency of Good Agricultural Practice (GAP) and Hazard Analysis and Critical Control Point (HACCP) products, and the propensity for health-related products was measured by the purchasing frequency of home meal replacement (HMR) and hedonic products. The propensity to purchase familiar brands was measured using a questionnaire. Logistic regression was used to examine the determinants of the KNC purchase experience, and multiple linear regression was used to determine the factors that influenced the KNC purchase frequency. The results showed that unemployed women purchased more safety certified products, health-related products, familiar brands, and KNC. These findings suggest that targeting consumers with differential marketing strategies may help promote KNC consumption. This study identified factors that influence KNC purchases, which is important for understanding consumer behavior and revitalizing the market.

In South Korea, social, the number of single-person households has rapidly increased because of financial factors. Since single-person households have characteristics differentiated from general households, many enterprises pay attention to them that appear as important consumers. This study conducted a survey with consumers in their 20s to 50s in single-person households, nationwide who had an experience of purchasing HMR. The results of this study can be summarized as follows: First, of the benefits pursued in dietary life, the pursuit of nutrition a negative (-) impact on RTH type and did not have any impacts on the RTE and RTC types. The pursuit of taste had a positive (+) impact only on the RTE type while it did not have any impact on the RTH and RTC types. The pursuit of convenience had positive (+) impacts on all RTH, RTE and RTC types, while the pursuit of price sought did not have any impact on all types. Second, of the preferences by each HMR type, preferences for the RTH and RTC types had positive (+) impacts on purchase intention while preference for the RTE type did not have any impact on purchase intention. Third, of the benefits pursued in dietary life, the pursuits of taste and convenience had positive (+) impacts on purchase intention while the pursuits of nutrition and price did not have any significant impacts on purchase intention. In addition, of the benefits pursued in dietary life, the pursuit of convenience had a significant impact on purchase intention mediated by preference by each HMR type. As a result, taste of HMR and the aspects of convenience act as factors inducing purchases, and products in the various forms of taste and convenience in order to appeal consumers who pursue taste and convenience.

Purpose : Because there is a difference depending on the environment as for an inspection equipment the important part of bone density scan and the precision/accuracy of a tester, the management of quality must be made systematically. The equipment failure caused by overload effect due to the aged equipment and the increase of a patient was made frequently. Thus, the replacement of equipment and additional purchases of new bonedensity equipment caused a compatibility problem in tracking patients. This study wants to know whether the clinical changes of patient's bonedensity can be accurately and precisely reflected when used it compatiblly like the existing equipment after equipment replacement and expansion. Materials and methods : Two equipments of GE Lunar Prodigy Advance(P1 and P2) and the Phantom HOLOGIC Spine Road(HSP) were used to measure equipment precision. Each device scans 20 times so that precision data was acquired from the phantom(Group 1). The precision of a tester was measured by shooting twice the same patient, every 15 members from each of the target equipment in 120 women(average age 48.78, 20-60 years old)(Group 2). In addition, the measurement of the precision of a tester and the cross-calibration data were made by scanning 20 times in each of the equipment using HSP, based on the data obtained from the management of quality using phantom(ASP) every morning (Group 3). The same patient was shot only once in one equipment alternately to make the measurement of the precision of a tester and the cross-calibration data in 120 women(average age 48.78, 20-60 years old)(Group 4). Results : It is steady equipment according to daily Q.C Data with $0.996\;g/cm^2$, change value(%CV) 0.08. The mean${\pm}$SD and a %CV price are ALP in Group 1(P1 : $1.064{\pm}0.002\;g/cm^2$, $%CV=0.190\;g/cm^2$, P2 : $1.061{\pm}0.003\;g/cm^2$, %CV=0.192). The mean${\pm}$SD and a %CV price are P1 : $1.187{\pm}0.002\;g/cm^2$, $%CV=0.164\;g/cm^2$, P2 : $1.198{\pm}0.002\;g/cm^2$, %CV=0.163 in Group 2. The average error${\pm}$2SD and %CV are P1 - (spine: $0.001{\pm}0.03\;g/cm^2$, %CV=0.94, Femur: $0.001{\pm}0.019\;g/cm^2$, %CV=0.96), P2 - (spine: $0.002{\pm}0.018\;g/cm^2$, %CV=0.55, Femur: $0.001{\pm}0.013\;g/cm^2$, %CV=0.48) in Group 3. The average error${\pm}2SD$, %CV, and r value was spine : $0.006{\pm}0.024\;g/cm^2$, %CV=0.86, r=0.995, Femur: $0{\pm}0.014\;g/cm^2$, %CV=0.54, r=0.998 in Group 4. Conclusion: Both LUNAR ASP CV% and HOLOGIC Spine Phantom are included in the normal range of error of ${\pm}2%$ defined in ISCD. BMD measurement keeps a relatively constant value, so showing excellent repeatability. The Phantom has homogeneous characteristics, but it has limitations to reflect the clinical part including variations in patient's body weight or body fat. As a result, it is believed that quality control using Phantom will be useful to check mis-calibration of the equipment used. A value measured a patient two times with one equipment, and that of double-crossed two equipment are all included within 2SD Value in the Bland - Altman Graph compared results of Group 3 with Group 4. The r value of 0.99 or higher in Linear regression analysis(Regression Analysis) indicated high precision and correlation. Therefore, it revealed that two compatible equipment did not affect in tracking the patients. Regular testing equipment and capabilities of a tester, then appropriate calibration will have to be achieved in order to calculate confidential BMD.
