This study was conducted to investigate the effect of crude saponin of red ginseng and aqueous extracts from several medicinal herbs on the activity of alcohol dehydrogenase(ADH) and aldehyde dehydrogenase(ALDH) in alcohol metabolism. In order to develop a liquid phase product a model product was prepared using functional plants. In case of red ginseng crude saponin, and some medicinal herbs(Puerariae radix, the flower of Puerariae lobata, the fruits of Hovenia dulcis Thunb., Morus alba L.) the relative activity of ADH was significantly increased, which was from 104~114%. The relative activity of ALDH was also significantly increased in the cases of the fruits of Hovenia duicis Thunb., Morus alba L. which was from 102∼106%. To improve of soju flavours by addition of liquid phase product, it is prepared three samples added a given content (0.28%) of chik, ssanghwa and kyungokgo flavour. The total acceptability test showed significant differences among three samples, and it is observed that the sample added ssanghwa flavour get the best grade. As the second acceptability test, the preference of ssanghwa flavoured sample, sample without flavour and a similar product in market was compared. There was no significant difference among three samples.
Tomato (Lycopersicon esculentum M.) is one of the most important crops to the fresh vegetable market and the food processing industry. To evaluate genetic variation in tomato fruits, major characteristics such as soluble solids, acidity and carotenoid contents were analyzed for 771 genetic resource lines. Lines in red color was about 85% which is the largest one followed by peach color, yellow, green, orange, and black. The sweetness of juice ranged from 2.2 to 11.5% (in brix), the average being 5.6%. The acidity ranged from 0.124% to 1.665%, and the average was 0.881%. The lycopine contents was up to 80.4 ${\mu}g/g$, and 43.4 ${\mu}g/g$ in average. ${\beta}$-carotine ranged 1.8 to 48.8 ${\mu}g/g$ and it average was 10.8 ${\mu}g/g$. Statistical analysis indicates that there is coefficient of correlation between acidity and sweetness, acidity and pH, pH and lycopine, lycopine and ${\beta}$-carotine. It is expected that the result of this study can be used for breeding more competitive species with respect to contents in sugar or functional chemicals from the selected characteristic species.
In order to investigate the composition and the actual status of extractive nitrogenous compounds in the fresh 'Gae-bul' (echiuroid), a kind of echiurida (Urechis unicinctus), the extract was analyzed separately into extractive nitrogen, free amino acids (FAAs), oligopeptides, nucleotides and related compounds, quaternary ammonium bases, and guanidino compounds, using specimens collected at fish market in April 1988. The extractive nitrogen of echiuroid was $601{\sim}610mg/100g$. Thirty-two kinds of FAAs were found, and the total of them in it was $2,437{\sim}2,609\;mg$. Glycine, alanine, taurine, and serine were the major FAAs in the echiuroid extracts. The large amount of glycine $(1,075{\sim}1,171mg)$ was noted in the extract. The sum of ATP and its related compounds was $3.04{\sim}3.12\;{\mu}mol/g$, and predominant compound was the AMP. Besides, CTP, GTP, UTP and their related compounds were also detected, and the total amount of them was $1.92{\sim}3.74\;{\mu}mol/g$. The lower homarine, trigonelline, TMAO, TMA, and creatine were detected in the extracts. The extractive nitrogenous constituents of medium size and large size echiuroid were almost the same level each other. The total nitrogens of the compounds analyzed for each samples accounted for more than 90% of the extractive nitrogen in this study.
These days fashion market is overflown with many brands and their identities are not so clear that the advertisement emphasizing the characteristics of the products don't seem to be adequate in appealing the customers. Therefore it is required that the sensible image advertisement which appeals to the customers by stimulating their feeling and sensitivity to attract customer's interest. At that point, VMD especially of POP advertisement that can be attract direct purchasing plays an important part to build up the accurate image of brand to consumers. Even thought today's individualized consumers take much interested in the fresh and original expressions, the visual expressions of fashion advertisements still focus on using photographs. The most advertisement of photograph has a limit that it shows only an immediate fraction, so it can't present whole image It can deliver more- imaginations and message than photograph if fashion illustration is used in advertisement. Therefore the purpose of this study was to present the application of fashion illustration for the POP advertisement Twelve pieces of fashion illustrations were produced and classified three parts according to their images and expression techniques. Paper sculpture techniques were applied for fashion image expression, for paper is easily meet daily life and ecological materials. For study procedure and contents, the concept and useful functions of fashion illustration and the concept of paper sculpture were examined as a theoretical background, and various uses and techniques of paper sculpture by analysing a number of paper sculpture art works were also studied. Also the concept, roles and functions of POP advertisement were discussed, and then the examples that the fashion illustration applied in the advertisement were analyzed through case study. The theme of my works was jean fashion brand whose brand image is significant, Twelve pieces of fashion illustrations using paper sculpture techniques were produced and various kinds of paper were used in expressing the paper sculpture technique. Each works were cut out the forms and used a pertinent light for making cubic effect shadow when displayed them. In my works Ⅰand Ⅱ, Ⅰ illustrated jeans in two images of sexy and casual, these were created slightly bigger than actual body size in order to attract consumer's gaze at show window or store. In my works Ⅲ, Ⅰ illustrated part or model of a jean product so that it could be used as addition to main display.
For the purpose of improving the precooked frozen food, the processing conditions of sardine steaks and the effect of soybean protein and corn starch on quality of the products during frozen storage were investigated. Fresh sardines were purchased from Busan Central Whole Sale Market and filleted. And then sardine meats were separated from fillets by fish meat separator. The meats were mixed with 0.5% sodium bicarbonate, 1.5% of table salt and 0.2% of polyphosphate, monosodium glutamate, white pepper, garlic powder and nutmeg, respectively. The mixture was minced with the stone grinder and filled in polyvinylidene chloride film tube and then stored at $-3^{\circ}C$ for 36 hours prior to frozen storage. Sardine steaks containing 3% of soybean protein were superior to those of containing 3% of corn starch or without soybean protein and corn starch on texture and eating quality of them during the period of frozen storage. It is convinced that addition of 3% of soybean protein to the sardine steak was benefically effective for the control of free drip, oxidative rancidity and the improvement of texture. The quality of frozen sardine steaks, by sensory evaluation, were preserved in good eating quality for 90 days during frozen storage.

This study was conducted to figure out the possibility of non-drainage in muskmelon (Cucumis melo L.) hydroponics culture. Plants were grown under 3 different levels of drainage, standard (20~40%, SD), minimum (5~10%, MD), and non-drainage (ND). Throughout cultivation periods, constant water content and electrolyte conductivity changes in root zone were observed in SD in the range of 60~70% and $1.5{\sim}2.5dS{\cdot}m^{-1}$, respectively. ND treatment caused the fluctuation in water content and electrolyte conductivity of root zone and its change ranges were 30~50% in water content and $2{\sim}6dS{\cdot}m^{-1}$ in electrolyte conductivity, but ND treatment did not decrease fruit quality. Even if fruit fresh weight was slightly lower in ND with 1,863 g, than in SD with 1,990 g, the fruit weight in ND meets standard market size, 1,800~2,000 g. Higher soluble solids content was observed in fruit in ND than in SD and MD. Total amount of drainage per plant was 27,718, 15,769 and 2,346 mL in SD, MD and ND, respectively. SD showed $83.2m^3$ drainage, 34.5% drainage of irrigation amount whereas required total irrigation amount in ND was very low with $7m^3$.
This study aims to explain the emergence of Gangnam Region of Seoul as a new cluster of the Korean film industry in the context of its history of growth, recent development characteristics, and its production system. Statistical analyses of Korean industries and in-depth interview surveys to film producers were conducted. The results of the analyses show that there has been obvious tendency of film makers' move from Chungmuro, a traditional cluster of the Korean film industry, to Gangnam and many births of new film makers in Gangnam. This new cluster, however, is operating on informal networking between film makers and related personnel, not on formalized production system composed of specialized functions and labor market. Therefore, it can be called as loosely-articulated cluster. This form of cluster has much to do with production milieu of Gangnam, such as advantages of obtaining information and consumer trend, diverse atmosphere which makes it easier to meet diverse people, favorable environment to embed creativity and fresh idea, etc. This trend of the film industry to orient a specific area can be explained in conjunction with the uniqueness of the film industry, such as uncertainty, project-based work, generation gap between film makers, participation of large companies or increasing size of investment.
This study was carried out to breed and develop high quality and functional nutrient tomato with multi disease resistance as well as a stable growing adaptation for fresh market usage under protected plastic houses cultivation. The materials were used 5 inbred lines and their 6 hybrids of large tomato group, which have been bred and developed from 1999 to 2007 in Division of Plant Resource Department of Chungnam National University. Fruit weight showed hybrid vigor effect that $F_1$ hybrids weighed more than their parent lines, fruit shape formed three type of oblate, deep oblate and globe shape, in firmness and pericarp thickness have got a high significant correlation, inbred DN611 line was measured the most firm fruit with 6.04 mm pericarp thickness. In fruit color at maturity, pink color crossed to red color appeared all red fruit color in the $F_1$ hybrids, it means red skin color is a dominant gene compared to pink skin color is a recessive gene in tomato, while between fruit skin color and shoulder part color showed no any co-relationship. The sugar content and titratable acid of $F_1$ hybrids inherited an intermediate data of their parent lines, the flavor of KP543 inbred line and the hybrid (JB535 x KP543) revealed the better taste with high brix and proper titratable acid content$^{*}$. In beta carotene content DN611 line showed 2~3 times higher than other materials so that its 3 hybrids contained an increased level of beta carotene, lycopene content was not so much difference among inbred lines and $F_1$ hybrids, of them MD508 contained higher of 8.72 mg and hybrid (JB535 x JA517) had 8.05 mg lycopene content per 100 g fruit, overall pink skin color and red skin color measured a higher lycopene content than yellow and orange skin color at ripe stage. In disease resistance test by PCR marker for Fusarium race2 (I2), Nematode (Mi1), ToMV ($Tm2^2$), Cladosporium (Cf9), (JB535 x JA517) hybrid have got multi-resistance with homozygote band in Nematode, ToMV, Cladosporium and heterozygote band in Fusarium race2. Through this breeding program we could select high quality and functional nutrient with multi resistant $F_1$ hybrids and inbred lines in tomato which are two best hybrids (JB535 x MD508), (JB535 x JA517), additionally developed high beta carotene inbred line DN611 and increased the level of lycopene inbred line MD508. These results will be very useful to make a high quality tomato variety continuously.
The effect of packaging methods on the quality characteristics of leaf lettuces was studied during storage at low temperature. Using five commercial packaging types: non-perforated PP (polypropylene) film bags, PP film roll, perforated PP film bags, PET (polyethyleneterephthalate) trays, and micro-perforated LDPE film bags, changes in color, respiration rate, and weight loss of leaf lettuces were investigated. Packaging in non-perforated PP film bags minimized color change and weight loss during storage. The leaf lettuces packaged in non-perforated PP film bags, among the five packaging choices, showed good external appearance and offered the greatest sale potential in the domestic market. However, there were no clear differences in the respiration rates of lettuces packed in various ways. The PET tray afforded very good protection of leaf lettuces from physical damage. The results indicate that the marketability of lettuces may be directly affected by the packaging modes employed, and that the optimal packaging may be non-perforated PP film bags; these keep lettuces fresh during low-temperature storage.

'Fuyu' (Diospyros kaki L.) is an important sweet persimmon cultivar, and the fruits are often stored in a modified atmosphere after harvesting in South Korea. However, blossom-end browning and darkening of fruit often occur after harvest or during storage, which decreases fruit quality in the fresh fruit market. High fruit calcium concentration would reduce oxidation of phenolic compounds in the cytoplasm such oxidation is responsible for fruit browning. This study investigated the effects of soluble calcium fertilization and foliar application, and indole-3-butyric acid (IBA) fertilization on fruit quality and browning. Trees received one of the following five treatments: 1) control (no calcium or IBA); 2) calcium fertilization (Ca FG, 2 mL per tree); 3) calcium foliar application (Ca FA, 2 mL); 4) calcium and IBA fertilization (Ca+IBA) 5) IBA fertilization (IBA, 2 mL. Fruit calcium concentration was highest in trees treated by Ca FA, and lowest in control trees. Generally, fruit calcium concentration was high in the stem end but low in the blossom end, which usually first develops fruit-browning symptoms. There were no apparent differences in fruit qualities such as firmness, soluble solid content, and weight among treatments. Fruit browning occurred at frequencies of about 14%, 20%, and 50% on Ca FA, Ca FG, and control trees, respectively. Therefore, the improved fruit calcium level seen when trees received Ca or IBA application tended to prevent fruit browning, which increased fruit quality and storage properties.
