  • This study was conducted to develop an edible smoked egg by penetrating seasoning through pressurization without damaging the eggshell and to investigate the quality characteristics of the product. The lyophilized smoked egg consisted of 2.43% moisture, 4.11% crude ash, 46.08% crude protein, 40.85% crude fat and 6.53% hydrated carbon. The total content of polyphenol was 3.11 mg%, 35.70% saturated fatty acid and 64.30% unsaturated fatty acid. Major types of saturated fatty acids included palmitic acid (C16:0), stearic acid (C18:0) and lauric acid (C12:0), while major unsaturated fatty acids included oleic acid (C18:1) and linoleic acid (C18:2). Due to smoking of the egg, the eggshell is dark brown, the egg albumen, egg yolk and egg shell are darker than boiled eggs, and the value of a (redness) is higher than that of boiled eggs. Overall, smoked eggs were organically superior than boiled eggs because of their seasoning and smoke flavor. The results of this study are expected to further the development of processed foods using domestic eggs and improve the egg processing industry.

  • Soil testing laboratories unfamiliar with turfgrasses will often overestimate the plant's need for phosphorus and underestimate the need for potassium. This is partly due to differences in rooting between grasses and many garden plants and crops. The grasses are generally more efficient in extracting phosphorus from the soil, reducing their need for phosphorus fertilizer. The fact that crop yield is often the primary objective in field crop production, and is usually of little interest in turfgrass management, may affect soil test interpretation for potassium. Potassium levels above those required for maximum tissue yield of grasses may improve stress tolerance and turfgrasses will usually benefit from higher applications of this element. There are also diffrrences in soil testing philosophies. Some laboratories use the sufficiency level of available nutrients(SLAN) approach, whereas others prefer the basic cation saturation ratio(BCSR) approach. Some will use a combination of the two methods. The use of the BCSR theory easily lends itself to abuse and questionable fertilizer applications and products are sometimes recommended citing imbalances in cation ratios. The usefulness of the BCSR ratio theory of soil testing varies with soil texture and interpretations on tests performed on sand-based media are particularly a problem. Other soil testing problems occur when sand-based media used on sports fields and golf greens contain free calcium carbonate. The ammonium acetate extractant at pH 7.0 dissolves excessive amounts of calcium that can bias cation exchange capacity measurements and measurements of cation ratios. Adjusting the pH of the extractant to 8.1 can improve the accuracy of the testing procedure for calcareous media.

  • This study aimed to optimize the preparation method of citron (Citrus junos Sieb.) beverages with hibiscus using response surface methodology (RSM). The experimental conditions were established using a central composite design with three independent variables as follows: ratios of citron (40~60%), citric acid (0.34~0.94%), and hibiscus (0.3~0.7%). The results indicate that an increase in the citron ratio contributed to increased sweetness and as the concentration of citron and hibiscus increased, the brightness of the citron beverage decreased and the yellowness increased. The citron ratio showed a significant correlation with the ABTS radical scavenging capacity. Among the 15 experimental groups, 4 representative samples showing statistical significance were selected, and sensory tests were performed, in comparison with commercially available products. As a result of the sensory test, four beverages prepared with the selected recipes showed higher preference than commercial beverages, and optimal recipe conditions were 40% citron, 0.34% citric acid, and 0.5% hibiscus.

  • Cheesemaking is believed to have been first practiced in prehistoric times, about 9,500 years ago, in the area around the Fertile Crescent of Mesopotamia and they left legacy in the name of cheese. Father Chi Chong-Hwan(Didier Serstevens) started for his provost in Imsil Catholic church in 1964. In 1968, cheese was first produced Camembert in Korea by Father Chi Chong-hwan, and then made Mozzarella in 1970, Cheddar in 1972. Father Chi lay the foundation of a cheese industry in Korea. The processed cheese market was highly grown after putting on the market of sliced cheese in the late 1980s, and the various products that complied with wellbeing trends such as organic and high functional cheese produced in the 2000s. The natural cheese opens up a new domestic market after producing Camembert and Brie cheese in the end of 2004. At present, major trends in cheese are authenticity, bold flavor, snack sophistication and tradition. Mozzarella, Parmesan, Cheddar, Provolone, Feta cheese still top in foodservice. In Korea, production of natural cheese is decreasing by the influence of the imported cheese. Production of processed cheese is increasing and total consumption of cheese is also increasing year by year.

  • This study is conducted to provide marketing implications for the growing pet-related market by identifying the impact of attachment to pets on the purchasing attributes of pet goods and the relationship between the purchasing attributes, satisfaction, and behavioral intention.The survey was conducted on 173 respondents among the pet owners who had purchased pet products (beauty/bathing goods). The confirmatory factor analysis and path analysis were conducted using SPSS 22.0 and AMOS 21.0. This analysis results showed that attachment to a pet significantly influences the purchasing attributes of pet products: price appropriateness, quality, design, reputation and the sales environment. The relationship between the product purchasing attributes, satisfaction, and behavioral intention showed that price appropriateness, quality, and the sales environment of the product purchasing attributes had a significant impact on satisfaction, but the product's design and reputation do not. Satisfaction has a significant effect on behavioral intention. This study demonstrates that the pet product market should consider product quality, price appropriateness, use and an accessible sales environment based on the characteristics of pets rather than considering the design or reputation of the owner's preference of product.

  • The purpose of this study is to investigate the effect of transaction characteristics on transaction cost and choice intention by applying transaction cost theory to experiential product. Experience-specificity, transaction uncertainty, and personal uncertainty are proposed to reflect the characteristics of experiential products, and the effects of these variables on transaction costs and transaction costs are assumed to have an influence on the choice intention. The results of this study are summarized as follows. First, experience-specificity(site, physical equipment, knowledge skill, temporal), transactional uncertainty(product-, process-), personal uncertainty (preference-, and situation-) have a significant positive effect on transaction cost. Second, transaction costs (search, comparison, examination, negotiation, payment, delivery) have a significant negative effect on the choice intention of the experiential product. The results of this study show that the increase of transaction costs can reduce the choice of experiential products and the strategic consideration of experience specificity, transaction uncertainty and individual uncertainty are required to reduce transaction costs. In addition, experiential products lacked access from a transactional and cost-based point of view, and this study contributes theoretically by compensating for the lack.

  • An autonomous driving system is based on the deep learning system built by big data which are obtained by various IoT sensors. The miniaturization and high performance of the IoT sensors are needed for diverse devices including the autonomous driving system. Specially, the miniaturization of the sensors leads to compel the miniaturization of the fixer structures. In the viewpoint of the miniaturization, metallic structure is a best solution to attach the small IoT sensors to the main body. However, it is hard to manufacture the small metallic structure with a conventional machining process or manufacturing cost greatly increases. As one of solutions for the problems, in this work, metallic FDM (Fused depositon modeling) based on metallic filament was proposed and the FDM process was investigated to fabricate the small metallic structure. Final part was obtained by the post-process that consists of debinding and sintering. In this work, the relationship between infill rate and the density of the part after the post-process was investigated. The investigation of the relationship is based on the fact that the infill rate and the density obtained from the post-processing is not same. It can be said that this work is a fundamental research to obtain the higher density of the printed part.

  • Many companies are operating and introducing the research results that corporate counseling contributes to corporate profits and improves the effective welfare of workers. This study was conducted targeting business management experts. As a research question, first, is there a difference in perception among business management experts about business counseling? Second, what is an important marketing 7P mix for revitalizing corporate counseling? Third, there will be differences in the importance of the 7P mix for marketing among business management experts. The results of the quantitative study are as follows. First, business management experts had a positive perception about the intention and necessity of corporate counseling, and marketing was higher than production management by field. The consultation model prefers an external model, and medium-sized enterprises and small and medium-sized enterprises are selected as target companies, and service and manufacturing industries are selected as target industries. The topics are recognized as interpersonal relationships and job stress. Second, price mix, product mix, people mix, and process mix are recognized as important marketing mixes, but companies consider the price mix the most important. Third, there was a difference between corporate management experts in the promotion mix and process, and marketing recognized the promotion mix as important and the process mix was important for financial management. However, there is no difference in the mixes by field except for this, so it can be said that the perception of the marketing mix is similar. Through this study, it is meaningful to present the implications of the marketing mix for awareness and activation of corporate counseling from the corporate point of view.
