This study examined the factors influencing the purchase intention of meat substitutes. A survey was conducted on 589 consumers in Korea (297 people) and China (292 people). The perception of meat substitute foods was lower in Korean consumers than in Chinese consumers, but there was no significant difference. The purchase intention of meat substitute foods was lower in Korean consumers than in Chinese consumers (p<0.01). Korean consumers' perception of meat substitute foods was higher in males than in females (p<0.01). The purchase intention of meat substitute foods also showed the same trend (p<0.001). Chinese consumers' perception of meat substitute foods was higher in males than in females. The overall purchase intention of meat substitute foods was significantly higher in males than in females (p<0.05). The perception of meat substitute foods by Korean consumers' was higher in their 40s and 50s than in their 20s and 30s. The purchase intention of meat substitute foods was also high in their 40s and 50s (p<0.01). On the other hand, the perception of meat substitute foods by Chinese consumers' was higher in their 20s and 30s than in their 40s and 50s (p<0.01). The purchase intention of meat substitute foods also showed the same trend (p<0.01). Korean consumers' perception of meat substitute foods had a significant positive effect on the purchase intention of meat substitutes (p<0.001). Chinese consumers' perception of meat substitute foods also had a significant positive effect on the purchase intention of meat substitute foods (p<0.001).

This study analyzed the substitute behavior of mothers of infants or elementary-school-aged children in terms of consumption. For this study, in-depth interviews were conducted with women residing in the Seoul metropolitan area who show significant interest in their children. The interviews were analyzed based on the grounded theory. The findings of this study are as follows. First, mothers show substitute behavior for their children's appearance. The younger the children, the more substitute consumption exhibited by mothers. As children grow older and are able to choose what to wear, mothers show less substitute behavior tendencies regarding appearance management. Second, mothers tend to exhibit substitute behavior regarding their children's academic achievements. Mothers hope their children will be more successful than themselves were or will achieve the dreams that they failed to accomplish, which drives substitute behavior. Mothers affectionately provide children with financial support so they can obtain academic achievement and they hope their children will have successful occupations in the future. Third, mothers who are not satisfied with their appearance and have low self-esteem are more likely to exhibit substitute behavior with their children. This study will be helpful in understanding mothers' motivation and psychological factors regarding the support of their children.

This study was carried on the oxidative stability and the real practice possibilities in cooking of fat replacer MCT. Nowadays, it was known that fats and oils had become causes for cardiac disease, obesity and cancer, so the new materials were needed for fat substitute that has less fat contents and low calories. The food industry concerned about fats and oils had been researched and developed new and various kinds of substitute fats. MCT(medium chain triglycerides) is one of the fat based fat substitutes used as fat replacers. The POV of com germ oil(CO), soybean oil(SO), shortening(ST), butter(BT), their blended oil with MCT 10-50%(w/w), and MCT were determined and oxidative stability by POV was compared MCT with those of them. MCT has shown higher oxidative stability than CO, SO, ST, BT, so oxidative stabilities in all kinds of blended oils become higher and higher by the increased substitution ratios. In case of bread, the volume of bread prepared with MCT(MCT bread) substituted for ST at 10-40% level(w/w) were increased a little comparing to that made of shortening(ST bread). But degree of gelatinization of MCT bread were a little lower than ST bread, at the substitute ratio above 40%, the degree of gelatinization were reduced greatly. These phenomena were sustained in 9 stored days. While baking losses of MCT breads were almost same as ST bread until 30% substitute ratio, and the appearances of MCT breads were similar to ST bread until 40% substitute ratio. Also rheological properties and color(Lab) of MCT breads had shown no different significantly from ST bread until 20% substitute ratio, but by the results of sensory evaluation, overall acceptance including appearance, color, flavor, taste, texture of MCT breads were recognized almost same as ST bread by panel until 40% substitute ratio. Depends on the above results, we can suggest that 30-40% of MCT will substitute for shortening in making bread in order to reduce fat and calories intake amounts.

Metakaolin is a cementitious material for producing high-strength concrete. This material is now used as substitute for silica-fume. In this paper, we tested the compressive strength of concrete according to the substitute ratio of metakaolin, silica-fume. And we did the durability test such as chloride ion diffusion and chemical attack. In the compressive strength test, the result shows that $10\%$ substitute of metakaolin & silica-fume for binder is optimum. In the chloride ion diffusion test, according to the increase of substitute of metakaolin & silica-fume for binder, the diffusion coefficient is more reduced. And in the chemical attack test, according to the increase of substitute, the resistance is more excellent. In the durability test, we recognized that metakaolin is able to used as a substitute for silica-fume.

Purpose - This study aims to compare the requirements under the United Nations Convention on Contract for the International Sales of Goods (CISG) and the Korean Civil Act (KCA) regarding the buyer's right to require the delivery of substitute goods. The buyer's right to demand substitute delivery not only protect them from the seller's breach of contract but also preserves the contractual bond between the parties by providing an opportunity for sellers to protect their goodwill and circumvent the extreme remedy of avoidance. However, as substitute delivery entails additional efforts and costs for return and re-shipment, this right should not be allowed in every case of defect. Additionally, unlike the CISG, the KCA contains no specific provision related to the requirements for claiming substitute delivery. Therefore, it would be meaningful to examine and compare what requirements should be fulfilled before the buyer exercises the right in relation to non-conforming goods under the CISG and the KCA. Design/methodology - We conducted a comparative study of the requirements under the CISG and the KCA regarding the buyer's right to require delivery of substitute goods given a seller's delivery of non-conforming goods. Additionally, we referred to the opinions from the CISG Advisory Council, the draft of the KCA amendment, and related precedents, mainly focusing on the existence and severity of defects, reasonableness, and timely notice and requests as the major requirements for substitute delivery. Findings - The results of this study can be summarized as follows: First, the CISG provides more detailed requirements about the right to require delivery of substitute goods; by contrast, the KCA does not stipulate any such requirement. Thus, specific requirements for substitute delivery should be included when amending the KCA. Second, the CISG attempts to minimize overlapping and conflict with other remedies by specifying detailed requirements for the delivery of substitutes. Third, both the CISG and KCA require reasonableness for substitute delivery. Originality/value - Although there are no explicit legal requirements for substitute delivery under the KCA, there has been relatively little discussion of this issue to date. Therefore, the findings of our study can guide future revisions of the KCA to fill this loophole. Moreover, the recently released CISG Advisory Council opinion that clarifies the continuing confusion and debate, can help distinguish which remedy is suitable for a particular case. It may provide practical advice for businesspeople in international trade as well as legal implications for the future development of the KCA.

This study consists of instrumenting and running tests on variable compression engines and measuring the following combustion characterics: (a)flame speed, (b) emission and (c)performance parameter such as power and economy. The results were as follows: 1) The phase separation diagram of substitute fuels were obtained from phase separation experiment. 2) The flame propagation speed of substitute fuels were higher than gasoline and increased with increasing methanol weight percent of substitute fuels. 3) BEMP of substitute fuels was slightly less than that of gasoline but in the range of small weight percent, BEMP was compatible to gasoline. 4) Concentration of NOx decreased significantly with delaying spark advancing time. Also, it decreased for rich equivalence ratio but increased with high compression ratio. In general, NOx concentration was much lower than that of gasoline. 5) Concentration of HC and CO increased for rich equivalence ratio. Also it was lower than that of gasoline.
