According to Chomskyan grammar, humans can generate and understand an unbounded number of grammatical sentences. Against the background of pure and idealized linguistic competence, this linguistic productivity is argued and understood. In actual utterances, however, there are many limitations of productivity but they are said to come from the general constraints on performances such as capacity of short term memory or attention. In this paper I discuss a problem raised against idealized productivity. I argue that linguistic productivity idealizes our linguistic competence too much. By separating idealized competence from the various constraints of performance, Chomskyan theorists can argue for unlimited productivity. However, the absolute distinction between grammar (pure competence) and parser (actual psychological processes) makes little sense when we explain the low acceptability(intelligibility) of center embedded sentences. Usually, the problem of center embedded sentence is explained in terms of memory shortage or other performance constraints. To explain the low acceptability, however, we need to assume specialized memory structure because the low acceptability occurs only with a specific type of syntactic pattern. 1 argue that this special memory structure should not be considered as a general performance constraint. It is a domain specific (specifically linguistic) constraints and an intrinsic part of human language processing. Recent development of Chomskyan grammar, i.e., minimalist approach seems to close the gap between pure competence and this type of specialized constraints. Chomsky's earlier approach of generative grammar focuses on end result of the generative derivation. However, economy principle (of minimalist approach) focuses on actual derivational processes. By having less mathematical or less idealized grammar, we can come closer to the actual computational processes that build syntactic structure of a sentence. In this way, we can have a more concrete picture of our linguistic competence, competence that is not detached from actual computational processes.

The purpose of this study was to develop an excellent salad dressing using grape seed oil, which contains high levels of unsaturated fatty acids. First, a vinaigrette was made with grape seed oil and vinegar and divided into five portions. Then, five types of mirepoix au maigre ($M_1,M_2,M_3,M_4,M_5$) were made with apple, onion, carrot, garlic, tomato puree, and tomato ketchup by mixing in a main material vessel. The samples were then allowed to ripen for three days. The control group $M_1$ was named $GD_1$, and the experimental groups $M_2,\;M_3,\;M_4,\;and\;M_5$ were named $GD_2,\;GD_3,\;GD_4,\;and\;GD_5$. respectively. To measure receptiveness, a sensory test was conducted using a 7 point category scale. The test concentrated on flavor, taste, color, agreeability, aftertaste, and overall acceptability: the panel consisted of 15 subjects According to the results, $GD_4$ had the best flavor, color and agreeability. The samples with the most preferred taste and aftertaste were $GD_4\;and\;GD_5$. Between $GD_4\;and\;GD_5$, there were no noticeable differences in taste, aftertaste, or overall acceptability, but differences in color and agreeability did exist. Thus, $GD_4$ proved to be the most favorable product. To determine the best complementing vegetables for $GD_4$ yam($VE_1$), broccoli sprouts($VE_2$), mustard leaves($VE_3$), beet leaves($VE_4$), cucumber($VE_5$), and lettuce(VE6) were selected as samples, and a sensory test was conducted. Each vegetable has its own peculiarities. According to the results, $VE_2$ had the nicest vegetable fragrance recording the highest mean value. The vegetable with the most preferred taste, aftertaste, and agreeability were $VE_2\;and\;VE_6$. $VE_1\;and\;VE_6$ had the nicest color and contained the brightest color as well. The highest overall acceptability was awarded to $VE_2\;and\;VE_6$ and there was no remarkable difference between thorn at a level of 0.05. In conclusion, $VE_2\;and\;VE_6$ were the best complementing vegetables with grape seed oil dressing. However, to commercialize such a dressing, many follow-up studies must be conducted.

In this study, the physicochemical and sensory characteristics of cream soups prepared with various levels of mulbery leaf powder were investigated. The pH, L-value, and viscosity of the cream soups decreased as the mulbery leaf powder content increased. The a-value -1.91 of the control was significantly higher than the other samples. The b-value of the sample with a mulbery leaf powder to flour ratio of 4:6 was highest at 38.59. Results of the descriptive tests showed that darkness, green aroma, bitter taste, and thickness had increased significantly, and savory flavor, greasy taste, floury taste, and softness decreased significantly as the content of mulbery leaf powder increased. A consumer acceptability test for sensory properties indicated that the mulbery leaf powder to flour ratio of 1:9 had the highest flavor and overall acceptability. Also, overall acceptability had positive correlations with savory aroma, savory flavor and softness, but had negative correlations with green aroma and thickness.

The effects of adding varying amounts (0%, 1.5%, 3%, 6%, and 12%) of the medium roasted coffee powder on the quality characteristics of rice cookies, which were prepared without wheat flour, were studied. The ingredients were mixed, cut, baked at $170{\sim}180^{\circ}C$ for 10 min, cooled, and packaged in plastic bags. Lightness ($L^*$), yellowness ($b^*$), chroma ($C^*$), and hue angle ($h^{\circ}$) of cookies decreased as the addition amount of the coffee powder increased. Redness ($a^*$) increased with the amount of the coffee powder. Firmness and phenolic compounds tended to increase with the increase in coffee content, however, the firmness levels of the cookies containing 1.5~3% coffee powder were insignificantly different. Antioxidant activity of cookies increased with the increase in the amount of coffee powder. Antioxidant activity of the cookies added with 3% coffee powder was significantly higher than that of the cookies added with 1.5% coffee powder. As a results of the sensory evaluation, the intensity of darkness, smell, bitterness, hardness of the cookies tended to increase with the increase in the amount of coffee powder. The overall acceptability of the cookies was significantly higher for the cookies containing 1.5~3% coffee powder than for the other samples. These results suggested that coffee powder (approximately 3%) can be utilized as an additive for preparing rice cookies which have simultaneously high antioxidant activity and acceptability.

The quality characteristics of cookies with 0%, 2%, 4%, 6%, and 8% acaiberry (Euterpe oleracea Mart.) powder added were analyzed through chemical and sensory evaluations. The moisture contents of the cookies were insignificant (p<0.05) as the acaiberry powder levels (0%, 2%, 4%, 6%, and 8%) increased. The pH values of the cookies were significantly reduced in all the acaiberry powder groups compared to the controls. According to the Hunter color of the cookies, tbe L-value (lightness) and the b-value (yellowness) significantly decreased (p<0.05), whereas the a-value (redness) increased when the acaiberry powder was added at different levels (0%, 2%, 4%, 6%, and 8%). The spread factor decreased significantly (p<0.05) with the acaiberry powder addition levels (0%, 2%, 4%, 6%, and 8%). The hardness of the cookies significantly decreased (p<0.05) according to the increase in the acaiberry powder level (0%, 2%, 4%, 6%, and 8%). The sensory evaluation of the cookies showed that those with 6% acaiberry powder added had the greatest of the color, taste, flavor, texture, and overall acceptability. These results showed that up to 6% acaiberry powder can be added to cookies.

In order to investigate the effect of vacuum levels in retort pouch on the eating-quality characteristics of the thermal processed packed rice, sensory evaluations were performed with retort pouched rice(Milyang-23) packed at the vacuum of 30 and 75 cm Hg in comparison with kettle cooked rice as a control. The mean hedonic scores of eating-quality characteristics were statistic-ally analyzed by using F-test, Duncan's multiple range test and simple correlations. F-values on appearance, stickiness, taste and general acceptability of rice samples were significant at 1 % level and that on flavor and hardness significant at 5% level respectively. The mean hedonic scores of appearance, flavor, taste and the general acceptability between retort pouched rice packed at the vacuum of 30 and 75 cm Hg were significantly different at the 55 level of probability according to Duncan's multiple range test. Those of stickiness among treatments were significantly different one another. Correlations between general acceptability and the other eating-quality characteristics of cooked-and packed-rice were significant with the exclusion of stickiness.

Effect of Rubus coreanum Miquel and Opuntia ficus-indica var. saboten in combination with chicken breast and wheat gluten on functional properties and physicochemical characteristics during processing of cooked noodles were investigated. These studies were carried out to investigate functional properties of Rubus coreanum Miquel and Opuntia ficus-indica var. saboten by the antioxidant ability. Antioxidant activities were evaluated by electron donating, xanthine oxidase inhibition rate and contents of total polyphenols. Overall, the antioxidant activities of hot water extracts were a little higher than those of ethanol extracts. Also, the antioxidant abilities at the concentration of 1,000 ppm in hot water extracts were higher than those of ethanol extracts by the determination of total polyphenol content and DPPH, which showed 150.25 mg% in extracts of Rubus coreanum Miquel and showed 69.36% in extracts of Opuntia ficus-indica var. saboten. The effects on processing characteristics of cooked noodles were investigated in combination with transglutaminase (TGase), plant extracts, wheat gluten and chicken breast. Cooking time was very short as 340 second in CB (cooked breast), compared to other treatments. In contrast, NCB (non cooked breast) took a longer time as 779 second. Also, CB was higher than NCB, which showed 146.3% in CB and 61.5% in NCB in water absorption ratio during cooking of noodles. Tubidity of soup was the lowest at 0.240 in NCBT (non cooked breast transglutaminase), which means the lowest loss of solid in noodle during cooking. In case of treatment of TGase, overall texture properties were higher than other samples in hardness, cohesivness, springness and gumminess. In sensory evaluations, cooked noodles treated with TGase showed a higher percentage of overall acceptability than other treatments.

The goal of this study was to develop a highly valuable Korean traditional ginseng wine containing various bioactive compounds with good acceptability. The effect of some medicinal plants on the quality and physiological functionality of Korean traditional ginseng wine were investigated. Advanced traditional ginseng wine (AG wine) prepared by addition of 0.5% each Pleuropterus multflorus and Pueraria lobata into the rice mash containing 1% ginseng, 0.4% Fermivin(commercial alcohol fermentation yeast) and Koji (2:1 mixture of nuruk and amylase containing 36 Saccharogenic power per g) showed the highest acceptability and ethanol content (16.8%). Changes of functionalities of the AG wine during fermentation at $25^{\circ}C$ for 30 days were investigated. The highest antihypertensive angiotensin I-converting enzyme inhibitory activity (78.9%) and total acceptability of the AG wine were shown after fermentation at $25^{\circ}C$ for 20 days. However, antioxidant activity, SOD-like activity and fibrinolytic activity of the AG wines were not detected or very low. HMG-CoA reductase inhibitory activity of the AG wine was also shown to be 8.2% and 9.2% after fermentation for 15 days and 20 days, respectively.

This study investigated the quality characteristics of bread made with different additions of Chungkukjang powder (0, 10, 20%). In the microbiological evaluations, total aerobic bacteria increased with increases in Chungkukjang powder concentration and storage period ($20^{\circ}C$, 3 days). The pH also increased with increasing Chungkukjang powder concentration. For the color values, with increasing Chungkukjang powder content, the lightness (p<0.05) decreased in both the bread crumb and crust, while redness (p<0.05) increased. The yellowness decreased for the bread crust and increased for the bread crumb. Hardness and chewiness were higher, but springiness and cohesiveness were lower, in the breads made with 10 or 20% Chungkukjang powder as compared to the control. The control bread obtained the highest sensory scores for texture and overall acceptability during the storage period. Optimum sensory scores for color, texture, and overall acceptability were obtained for the bread with 10 % Chungkukjang powder until day 1 of storage. From the results of this study, 10% Chungkukjang powder can be added to bread without diminishing its acceptability, but further study is necessary on extending shelf-life and improving consumer acceptance.

This study was conducted to evaluate the effect of Citrus peel powder on the quality characteristics of sponge cake. Citrus peel powder sponge cake was prepared with different ration of Citrus peel powder(0, 10, 20, 30, 40%). The specific gravity, baking loss rate and cake weight increases as the ratio of Citrus peel powder. The sponge cake's a, b level increased with the increasing level of Citrus peel powder 40% appeared to be the highest. In terms of textural characteristics, the samples containing 10, 20, and 40% Citrus peel powder had significantly higher hardness than the control samples. The substance's level of springiness, and cohesiveness decreased as the Citrus peel powder additive increased. In sensory evaluation, overall acceptability and taste of the cake was better than others when 10% Citrus peel powder was added. The results indicated that substituting 10% Citrus peel powder to sponge cake is optimal for quality and provides a product with reasonable high overall acceptability.
