  • Manufacturing technology for the production of high value-added fine chemical products is emphasized and getting more attention as the diversified interests of customers and the demand of high quality products are getting bigger and bigger everyday. Thus, the development of advanced batch processes, which is the preferred and most appropriate way of producing these types of products, and the related technologies are becoming more important. Therefore, high-precision batch distillation is one of the important elements in the successful manufacturing of fine chemicals, and the importance of the process operation strategy with quality assurance cannot be overemphasized. Accordingly, proposing a process structure explanation and operation strategy of such processes including batch processes and batch distillation would be of great value. We investigate optimal operation strategy and production planning of multi-purpose plants consisting of batch processes and batch distillation for the manufacturing of fine chemical products. For the short-term scheduling of a sequential multi-purpose batch plant consisting of batch distillation under MPC and UIS policy, we proposed a MILP model based on a priori time slot allocation. Also, we consider that the waste product of being produced on batch distillation is recycled to the batch distillation unit for the saving of raw materials. The developed methodology will be especially useful for the design and optimal operations of multi-purpose and multiproduct plants that is suitable for fine chemical production.

  • Purpose - This study was conducted to present a study on the perception and satisfaction with the brand agricultural products targeted at consumers who use a lot of local products. According to the data of 2011, the total number of the brand agricultural products of Korea is 5,291 with various kinds. Research design, data and methodology - The survey shows that the brand agricultural products are being used by some specific people. However, it can be a useful idea which can help the consumption of brand agricultural products to be expanded if we understand how consumers' recognitions are different between various groups. For an empirical Analysis, the response data of 110 adult patients residing in the metropolitan area were used and conducted with a factor analysis, frequency analysis in order to ensure the validity and conducted a regression analysis and correlation analysis using SPSS statistical program. Results - According to the analysis, it showed consumers with an interest in brand agricultural products are 40-50 age housewives and the middle class of about 5 million won in monthly income more than 3 million won with a college education. As for consumers' purchasing status, all the subjects said that they had experienced buying brand agricultural products and the level of satisfaction for them was very high. Relatively, consumers' satisfaction level with high income and education is high. And recognition of the brand agricultural products was found mainly goes through word of mouth. The age and income are very important factors in customers' repurchase for brand agricultural products. The result of the analysis for the influences on brand agricultural products of customer satisfaction suggests even if the recognitions for safety, quality, and value are vital factors, the recognition of quality doesn't influence on brand agricultural products statistically and significantly. It was analysed if there were any differences between recognitions by group to brand agricultural products, that is to say recognition of safety, quality and value and the result can be summarized as follows. There are all statistical significant differences depending on their age, educational background and income. In the case of 30 or 40 aged, as they got the education level of college and graduate school and earned relatively high income, most customers have positive recognition on the brand agricultural products. This implies the group which can buy and consume the brand agricultural more easily has much more positive recognition. Conclusion - The results of this study shows consumers' brand awareness and satisfaction with brand agricultural products are affected by their age and income level. The purpose of this study is to find the information that can help brand agricultural products markets to be expanded by understanding the factors which encourage consumers to behave repurchase as well as customers' various levels of recognition to the brand agricultural products. The survey says that brand agricultural products are being used by some specific people.

  • The objective of this study was to investigate the effects of canola and flaxseed oils on the physicochemical properties and sensory quality of emulsion-type sausage made from spent layer meat. Three types of sausage were manufactured with different fat sources: 20% pork back fat (CON), 20% canola oil (CA) and 20% flaxseed oil (FL). The pH value of the CA was significantly higher than the others (p<0.05). The highest water holding capacity was also presented for CA; in other words, CA demonstrated a significantly lower water loss value among the treatments (p<0.05). CA had the highest lightness value (p<0.05). However, FL showed the highest yellowness value (p<0.05) because of its own high-density yellow color. The texture profile of the treatments manufactured with vegetable oils showed higher values than for the CON (p<0.05); furthermore, CA had the highest texture profile values (p<0.05) among the treatments. The replacement of pork back fat with canola and flaxseed oils in sausages significantly increased the omega-3 fatty acid content (p<0.05) over 15 to 86 times, respectively. All emulsion sausages containing vegetable oil exhibited significantly lower values for saturated fatty acid content and the omega-6 to omega-3 ratios compared to CON (p<0.05). The results show that using canola or flaxseed oils as a pork fat replacer has a high potential to produce healthier products, and notably, the use of canola oil produced characteristics of great emulsion stability and sensory quality.

  • The purpose of this study is to examine the higher value-added characteristics of tailored jacket designs, which are major items of French luxury brands, in an effort to raise the competitiveness of domestic fashion designs. The characteristics of the jacket designs from the 1940s to the 1970s, the golden age of Haute Couture, were examined. Based on this, the characteristics of the higher value-added expressions of the luxury brands were established by analyzing the tailored jacket designs that appeared in the Paris collection after 2010. The results are as follows: the characteristics were categorized into 'traditional value expression,' 'conceptual value expression,' 'retro value expression,' and 'creative value expression.' Traditional value was expressed as the representation of the styles inherent to the golden age of the Haute Couture houses, and the status of the luxury brands with history was represented by equally arranging the size and characteristics of the elements of the designs related to jacket silhouette. Conceptual value was reestablished as contemporary identity into which the traditional ideology of the houses and the present designers' sentiments were grafted by developing the designs with the theme containing the identity of the past Haute Couture houses. Retro value was utilized as the strategy to differentiate the luxury brands with long history from contemporary products. Creative value was expressed as tailored jackets with new concepts of shape variation and usage conversion by combining creative sentiments with the high quality techniques of Haute Couture and appears to be able to create a new consumption market of luxury brands in the global fashion market.

  • In the assembly system, a pallet plays an important role of transfer and storage. As products become various, many different pallets are also necessary. Since some of them are redundant, a design of pallet with high flexibility is important. This paper suggests design alternatives, in designing pallets with high flexibility. The purpose of this study is to rationalize assembly process of mid-small size products. Every pallet has suitability values depending on characteristic factors of a product, and this value is determined by using AHP (Analytic Hierarchy Process) technique. As the characteristic factors of a product are changed, the suitability value is also changed. Design alternatives can be found by tracing change of the suitability value, which are based on correlation between the characteristic factors of a product and a pallet element.

  • Recently, Podaegi, a traditional Korean childcare product, are spreading abroad like a trend. Sites specializing in the sale of ' Podaegi have been created in the UK, France, and the US, and their popularity is increasing. In addition, China's preference for safe products and demand for global products and premium baby products are rapidly increasing. Nevertheless, the proportion of baby products in Korea is still very small. Therefore, this study seeks to find the differentiated value and direction of development of Podaegi by finding a form and method similar to Podaegi and overseas. The research method was reviewed based on literature research and actual cases. As a result, Podaegi has high practicality and emotional value, and attachment parenting is possible. When the stages of attachment parenting were compared and analyzed, it was confirmed that attachment parenting is possible for a wider age group than others, and that Korean traditional Podaegi has developed differently from Western ones, and that Korean Podaegi is very advantageous for attachment parenting. Therefore, in the future, Korea's Podaegi needs to meet overseas import standards, propose designs that fit the current situation, and promote and develop differentiated values abroad.

  • In this study the perception and consumption of processed meat products by students in food service schools was investigated. The total number of subjects in Seoul and Gangwon province used for this survey was 569. The most preferred processed meat product for students was the fried pork cutlet(17.7%), followed by bacon(11.4%), ham(7.9%) and sausage(7.6%). The main reasons for the consumption of these processed meat products were 'good taste'(52.5%), 'convenience in eating'(18.8%) and 'as the parent buy'(18.8%). The preference for the processed meat products had a relatively high perception value(4.0). However, the effect of consuming processed meat products on nutrition and health had a relatively low perception value(2.9). Reasons for distrusting the processed meat products were attributed to 'bad influence by media'(25.9%) and the 'unsanitary manufacture'(23.6%). In regards to the question about sodium nitrite, most of the students(56.2%) replied that they had 'never heard of it' or 'didn't know it well'. In conclusion, an improvement in public information would be a prerequisite for expanding wholesome use of processed meat products.
