According to the image level definition for KOMPSAT-2 in KOMPSAT-2 Ground Station Specification, the level 0 is frame formatted, unprocessed data at full resolution; any and all communications artifacts (e.g., synchronization frames, communications headers) removed. The level 0 is used for two purposes: 1) exchange of imagery between image receiving & processing element (IRPE), and 2) image transfer from the Receiving & Archiving Subsystem to Search & Processing Subsystem. On-board processing of imagery data of KOMPSAT-2 includes JPEG-like compression and encryption besides conventional CCSDS packetization. The encryption is used to secure imagery data from any intervention during downlink and compression allows real-time downlink of image data reducing data rate produced from the camera. While developing ground receiving system for KOMPSAT-2, it was necessarily to define level 0 products. In this paper, we will suggest level 0 product definition for KOMPSAT-2 and explain reasons of the decisions made. The key factor used while defining the level 0 products is the efficiency of whole ground receiving system. The latter half of the paper will explain the implementation of software that generates level 0 products. The necessary steps to produce level 0 products will be explained, and the performance achieved will be presented.

This study examined the differences on the amount of purchase of and willingness-to-pay more for organic products by socio-economic variables, knowledge and reliability of organic products, and concern for food. In addition the effects of the reliability and the price of organic products on the amount of purchase and willingness-to-pay more for organic products in the Path analysis. The results were below. First, consumers who had high education, were the age of 40's, high income, high level of knowledge and reliability for organic products were more likely to purchase organic products. Second, the level of willingness-to-pay more for organic Products were high when consumers with more than three children, not lowest level of health, and higher reliability. Third, the reliability of organic products impact the amount of purchase of organic products, but not the perception of organic products' price. Forth, both the reliability and the perception of those price impact the level of willingness-to-pay more for organic products.

3-Monochloro-1,2-propanediol(3-MCPD) was analyzed in soy sauce products commercially available in Korea. A total of 24 samples were collected and 3-MCPD was determined by GC/MS. Sources of 24 samples were classified by manufacturing methods as naturally brewed(NB), acid hydrolyzed (AH) and mixed (M = NB + AH) soy sauces. 3-MCPD was not detected in NB soy sauce products (< 0.01 ppm, mg/kg) whereas AH and M soy sauce products showed a wide range of 3-MCPD contamination (0.0l ∼ 2.038 ppm). The contaminated levels of 3-MCPD in soy sauce products were higher than the permissible or tentative permissible level of 3-MCPD in both European Community (0.02 ppm) and Korea (0.3 ppm). These data suggest that 3-MCPD levels contaminated in soy sauce products in Korea were shown to be too high and should be reduced to as low a level technologically feasible to protect Korean from the exposure to toxic chemical, 3-MCPD.

We developed a Near Real-Time Validation System (NRVS) for the Level-2 Products of AQUA Satellite. AQUA satellite is the second largest project of Earth Observing System (EOS) mission of NASA. This satellite provides the information of water cycle of the entire earth with many different forms. Among its products, we have used five kinds of level-2 geophysical parameters containing rain rate, sea surface wind speed, skin surface temperature, atmospheric temperature profile, and atmospheric humidity profile. To use these products in a scientific purpose, reasonable quantification is indispensable. In this paper we explain the near real-time validation system process and its detail algorithm. Its simulation results are also analyzed in a quantitative way. As reference data set in-situ measured meteorological data which are periodically gathered and provided by the Korea Meteorological Administration (KMA) is processed. Not only site-specific analysis but also time-series analysis of the validation results are explained and detail algorithms are described.

This study examined the customers' perception on Home Meal Replacement (HMR) products. Specifically, there were three research objectives: 1. to identify the customers' HMR purchase patterns and preference of HMR product development; 2. to identify the attributes of the HMR products that the customers perceive; and 3. to examine the customers' level of expectation-confirmation toward HMR product attributes according to the demographic characteristics. This study employed a self-administered survey that was distributed online from November 21~24, 2017. The sample of the study was the customers who had purchased HMR products in the six months prior to taking the survey. A total of 553 respondents completed the survey, which was used for data analysis. The results revealed the customers' HMR purchase patterns. The major HMR product type of purchase was ready to heat (52.6%), while the main reason for purchasing HMR products was convenience (83.2%). For the differences in the level of expectation-confirmation toward HMR products in accordance with the demographic characteristics of customers, the results indicated that there was a difference in the expectation-confirmation level according to age, whereas the respondents aged 29 and under showed a significantly higher level of time-saving for the preparation and ease of cooking (P<0.05) than the other age groups. In addition, there was a significant difference in the expectation-confirmation level for saving meal preparation time (P<0.05) and convenience (P<0.01) among the customer's occupation. These findings can provide the basis for a strategy for developing HMR products reflecting the rapidly changing customers' needs. HMR products should be developed according to the specific target market, as the study indicated that the respective customer segmentation resulted in a difference in their expectation toward HMR products.

In this study, the concept and techniques to generate the level lA, lB and 2A image products have been reviewed. In particular, radiometric and geometric corrections and bands registration used to generate level lA, lB and 2A products have been focused in this study. Radiometric correction is performed to take into account radiometric gain and offset calculated by compensating the detector response non-uniformity. And, in order to compensate satellite altitude, attitude, skew effects, earth rotation and earth curvature, some geometric parameters for geometric corrections are computed and applied. Bands registration process using the matching function between a geometry, which is called 'reference geometry', and another one which is corresponds to the image to be registered is applied to images in case of multi-spectral imaging mode. In order to generate level-lA image products, a simple radiometric processing is applied to a level-0 image. Level-lB image has the same radiometry correction as a level-lA image, but is also issued from some geometric corrections in order to compensate skew effects, Earth rotation effects and spectral misregistration. Level-2A image is generated using some geo-referencing parameters computed by ephemeris data, orbit attitudes and sensor angles. Level lA image is tested by visual analysis. The difference between distances calculated level 1 B image and distances of real coordinate is tested. Level 2A image is tested Using checking points.

Financial products entail either gains or losses, and customers' psychological reaction to these gains and losses affect the selection of the financial products. This study explains the financial customers' behavior by introducing consumers' psychological variables such as regulatory focus and construal levels. According to the regulatory focus theory, there are two distinct motivational orientations called promotion focus and prevention focus. And, construal level theory proposes that people use more abstract and higher levels of construal to represent objects that are more distant on psychological distance. We have incorporated these two psychological variables into financial consumer behaviors. In the experiment 1, the results have showed that promotion focused customers prefer fund products to deposit products, whereas prevention focused customers have showed the opposite result. In the experiment 2, both regulatory focus and construal level were considered. Specifically, under the high level message, promotion focused customers have showed higher preference to fund products than the prevention focused customers, and no significant difference for the deposit products. On the contrary, given the low level message, prevention focused customers have showed higher preference to both fund and deposit products than the promotion focused customers. Therefore, it comes to the conclusion that it will be efficient for the financial companies to use high level messages for the promotion focused customers and low level messages for the prevention focused customers. Implications and limitations are discussed to establish more effective marketing strategies based on the results of this study.

This study empirically confirmed how an art infusion into fashion products affect consumer's preference through Study 1 and Study 2. Study 1 examined the effect of an art infusion and the difference of an art infusion effect according to self-monitoring scale by designing groups composed of 2 (art infusion: infusion versus non-infusion) ${\times}2$ (self-monitoring: high versus low). Study 2 examined the difference of an art infusion effect according to the luxury level of fashion brands by designing groups composed of 2 (art infusion: infused versus non-infused) ${\times}2$ (fashion brand luxury levels: high versus mid versus low). This study was conducted using a convenience sample of women in their 20s and 30s residing in the Seoul and Daegu region. In Study 1, 162 participants were randomly assigned to two experiment situations of art infusion. In Study 2, 192 participants were randomly assigned to six experiment situations of art infusion and luxury level of fashion brands. For the data analysis, we conducted reliability analysis, two-way ANOVA and simple main effect analysis using SPSS 18.0 statistics package. The results of Study 1 and 2 are as follows. First, consumer's preference was shown to be higher for fashion products with art infusion rather than fashion products without art infusion. Second, the positive effect of art infusion on consumer's preference was significant in the group of high selfmonitors. But there was a non-significant effect of art infusion in the group of low self-monitors. Lastly, the positive effect of art infusion on consumer's preference is higher in the case of a mid-level luxury brand rather than in the case of a high-level luxury brand and low-level luxury brand.

Purpose - This study aims to proposes a conceptual framework to segment multi-national products based on a Chinese consumer's perception of multi-national products, to find the role of consumer ethnocentrism (CET) in country of origin (COO) effects for Chinese, and to figure out how different dimension of CET Effects on purchase intention developed market and home country. Research design, data and methodology - This study selected a 2×2×2 factorial design for the hypothesis test based on the product category × combination of manufactured type × Ethnocentrism level. This study distinguishes products between luxury (Burberry) and non-luxury (Nike) products and choose combination of manufactured type (Spain vs India/ Spain vs China) in order to perform comparative studies. A total of 223 Chinese participated in the experiment. After being exposed to each scenario, participants were asked to respond to questions about brand preference and purchase intention Results - Regarding to luxury made in developed country, it is worth that exposing COO information to low level of ethnocentrism consumers. Regarding to non-luxury product made in emerging country, it makes it worse when COO information to high level of ethnocentrism consumers. Lastly, regarding to non-luxury product, patriotic consumers prefer to purchase product made in home country.
