We stored sweet pumpkins at $8^{\circ}C$, $12^{\circ}C$, $12^{\circ}C$ plasma curing and room temperature (control) for 180 days. During this time, the quality characteristics were analyzed within the different groups. No spoiling occurred in either of the storage conditions for up to 120 days, and the marketability was good. After 120 days, spoiling sharply increased by over 70% in the control group, while in the $12^{\circ}C$ group it decreased to 20~60%. Conversely, spoiling was completely absent in the $8^{\circ}C$ and $12^{\circ}C$ plasma curing groups during the overall 180 days of storage. The lowest moisture content was found in the $8^{\circ}C$ group and the quality of the pumpkins was excellent during the entire storage period. The color of pulp was better in the $12^{\circ}C$ and $12^{\circ}C$ plasma curing groups, with best results were found in the latest. Both the $8^{\circ}C$ and $12^{\circ}C$ plasma curing groups maintained their dark green surface colors, while both the $12^{\circ}C$ and control groups turned from green to yellow. All groups showed a reduction in their initial hardness, with the $8^{\circ}C$ group staying the hardest. Soluble solid and mealiness was increased to the storage during 90 days while decreased, that were long to maintain the mealiness texture in the $8^{\circ}C$ storage pumpkin. The overall acceptability from sensory evaluation was higher in the $12^{\circ}C$ plasma curing group, when compared to those of the $8^{\circ}C$, $12^{\circ}C$ and control groups storage conditions.

This study was conducted to investigate total polyphenol contents and antioxidative effects of the enzymatic hydrolysates digested by several kinds of carbohydrases from the powder of ripened pumpkin (Cucurbita moschata), sweet pumpkin (C. maxima) and green pumpkin (C. moschata). The total polyphenol contents of all enzymatic hydrolysates from green pumpkin powder were higher than those of ripened and sweet pumpkins. DPPH radical scavenging activities of the enzymatic hydrolysates digested by AMG and Termamyl from green pumpkin were also very strong compared to ripened and sweet pumpkins. However, the most enzymatic hydrolysates of ripened and sweet pumpkin powders, except Viscozyme digestion, were higher superoxide anion scavenging activities than green pumpkin powder. Hydrogen peroxide scavenging activities in the enzymatic digests (not Ultroflo) of green pumpkin were potent compared to other pumpkin powders whereas hydroxyl radical scavenging activities were low at less than 14% in hydrolysates of all pumpkin species. Nitric oxide scavenging activities were very effective in Viscozyme digests of sweet and green pumpkin, and other enzymatic hydrolysates also showed higher activity than $\alpha$-tocopherol control (not BHT).
Powdery mildew is one of the most devastating diseases in cucurbits. Crop yield can decline as the disease severity increases. In this study, we evaluated the effect of silver nanoparticles against powdery mildew under different cultivation conditions in vitro and in vivo. Silver nanoparticles (WA-CV-WA13B) at various concentrations were applied before and after disease outbreak in plants to determine antifungal activities. In the field tests, the application of 100 ppm silver nanoparticles showed the highest inhibition rate for both before and after the outbreak of disease on cucumbers and pumpkins. Also, the application of 100 ppm silver nanoparticles showed maximum inhibition for the growth of fungal hyphae and conidial germination in in vivo tests. Scanning electron microscope results indicated that the silver nanoparticles caused detrimental effects on both mycelial growth and conidial germination.
The purpose of this study was to contribute to merchandising of native local foods. This study was designed to standardize the recipes and to analyze the nutrients of native local foods in Gijang region such as 'Myeolchijjigae', 'Galchijjigae' and 'Maejipjjim'. The test recipe for each food was prepared according to the information obtained from the personal interview of Gijang natives and then supplied for the sensory evaluation. After that, CAN Pro 2.0 was used for the nutritional evaluation. The results are as follows : Myeolchijjigae was preferred when radishes and traditional soybean paste were added. Galchijjigae was more liked when young pumpkins, mixed soy sauce and soybean paste were added. Maejipjjim was preferred with Aeji(Codium adhaerens), Warty sea squirt(Styela clava), soybean paste and powdered perilla seed(Perilla frutescens var. japonica) added. The analysis of nutrient composition revealed that in general energy content was low whereas protein content was as high as recommended requirement in Myeolchijjigae and Maejipjjim. Calcium and phosphorus were high in Myeol-chijjigae, vitamin A in Galchijjigae, and vitamin A, B_6$, folic acid, phosphorus and iron in Maejipjjim.

Objectives : In traditional Korean medicine literature, Succium(琥珀) is known to be effective in eliminating edema. However, pumpkins are misused in folk remedies to manage edema, because succium and pumpkin is homophony to 'Hobak' in Korean. The purpose of this study is to report the effects of Succium decoction on two patients with edema after plastic surgery. Methods : We treated two patients with edema after plastic surgery using Succium decoction. Numeric rating scale (NRS) of edema, photograph of changes in edema before and after treatment were analyzed to evaluate the effects of treatment. Results : After 2 weeks of administration, NRS for facial edema decreased from 5 to 3 and 2 to 1, respectively. Photograph of edema decreased after treatment, and there were no adverse events. Conclusions : This case report suggests that Succium decoction can be effective in treating edema after plastic surgery.
This study was conducted to investigate the cholesterol and Triglyceride (TG) lowering and anti-obesity effects of water extract of vegetable formula (onion 25%, carrot 20%, Cabbage 20%, Sweet Pumpkins 20%, Chinese plum 5%, turmeric 5%, morus leaves 5%, SLS) in mice fed high fat-diet. ICR mice were divided into 3 groups; a normal diet group (ND), a high-fat diet group (HFD), a high-fat diet and SLS with 300 mg/kg treated group (HFD+SLS). Body fat gain was increased by high-fat diet and HFD+SLS group showed a definite weight loss. The total cholesterol level in the HFD+SLS group was 328.4 mg/dl which was 27.4% lower than that in the HFD group and the cholesterol-lowering effect of SLS was confirmed. The HFD + SLS group showed 118.1 mg/dl and the triglyceride level in the serum was decreased by 88.7% compared to the HFD group and SLS significantly decreased blood triglyceride levels. RT-PCR showed that the expression of PPAR-${\gamma}$ and the target gene SCD-1 was inhibited in a dose-dependent manner in the SLS-treated group. These results suggest that the SLS water extract may have a cholesterol and triglyceride-lowering effect and inhibit the expression of PPAR-${\gamma}$ and SCD-1 to have an anti-obesity effect.
The purpose of this study was to evaluate the microbiological quality and assure the hygienic safety of the Bibimbap production in elementary school foodservice in accordance with the HACCP(Hazzard Analysis Critical Control Point) program. The time-temperature relationship and the microbiological quality(total plate count and coliform bacteria count) were assessed to find the critical control point(CCP) during each of the production phase. In the pre-preparation phase, the risk factors of the raw ingredients exceeded the standard level suggested by Solberg et al. Mungbean starch jelly, egg and Kochujang were satisfactory in that no coliform groups were observed over the standard TPC level. In particular, there was a high the risk of beef from the early stages in terms of the coliform level. In the pre-preparation phase, green pumpkin had more coliform groups than the standard level even after washed, which calls for special attention to washing, sterilization, secondary infection of the handler, and the required time for pre-preparation of raw vegetables. In the cooking phase, the temperature of the soybean sprout and mungbean starch jelly decreased to 42$^{\circ}C$ and 26$^{\circ}C$, respectively, which was within the risk zone. In particular, mungbean starch jelly had a great risk factor even after boiling in hot water. During the storage stage before serving, a lot of ingredients were exposed to poor management of temperature and time and thus exceeded the standard level in the total plate counts. In particular, the microbiological count of beef was five times the standard level. Green pumpkins and soybean sprouts were left at 15-38$^{\circ}C$ that is within the risk zone for a long period of time after they were cooked. It is highly recommended that the time of the storage stage before consumption should be shortened and that proper devices should be used to prevent proliferation of bacteria. The number of TPC of the utensils was satisfactory enough, but the knife used exceeded the standard level and thus was a risk factor of bacteria proliferation.
This study examined the characteristics of costumes worn at Halloween parties, a form of cultural entertainment commonly seen in the U.S. The Halloween party culture involves children and adolescents wearing costumes, decorating their bodies, and mimicking famous characters. Furthermore, the types and motifs of Halloween costumes have become a means of expressing individuality. This study conducted empirical research on how such motifs were reflected in modern Halloween party-wear in order to provide basic data regarding the development and design of Halloween costumes and the formation of the related entertainment culture. This study researched the shape of costumes and the type of traditional motif presented in these costumes, as well as analyzed the symbolic meaning of each motif. The research process was as follows. First, this study investigated the origin and evolution of Halloween by researching precedent studies, books, and internet data. Second, this study extracted the types of traditional Halloween motifs by analyzing the characteristics and symbols of Halloween costumes commonly presented in such materials. After collecting 547 Halloween-related images from U.S. and Korean Internet websites, this study sorted and analyzed images that could represent traditional Halloween motifs. According to the results, representative traditional Halloween motifs included black cats, white rabbits, tridents, scarecrows, skull and bones, ghosts, witches, vampires, bats, werewolves, and jack-o-lanterns(pumpkins, etc.). The sentiments for such traditional Halloween motifs changed according to era and race. The symbolic meaning would continuously change - from positive to negative and vice versa - to reflect various socio-cultural phenomena. The results of this study are expected to be used as basic data for developing Halloween costume designs and the related entertainment culture.
The purpose of this thesis was to develop pumpkin soup with different ratios of ingredients, using high-nutrient sweet pumpkins. P10G0 without sweet pumpkin and glutinous rice powder showed the highest moisture content, whereas, P5G0 whit Cheongdung pumpkin and sweet pumpkin at the same ratio whitout glutinous rice powder showed the lowest moisture content. For chromaticity lightness of control pumpkin soup scored the lowest. Lightness of P10G0 without sweet pumpkin and glutinous rice powder also scored the lowest. For redness, the P5 group with Cheongdung pumpkin and sweet pumpkin at the same ratio scored the highest while the P10 group without sweet pumpkin scored the lowest. As for yellowness, increased ratio of glutinous rice powder in pumpkin soup scored resulted in reduced yellowness in all groups P5 (p<0.01), P7 and P10 (p<0.001) A higher ratio of Cheongdung pumpkin was thus generally associated whit reduced yellowness (p<0.001). For the spread-ability, higher ratio of sweet pumpkin to Cheongdung pumpkin resulted in significant reduction of spread-ability. However, groups with 12% glutinous rice powder showed no significant differences. Spread-ability of the P5 and P10 groups significant increased and thereafter decreased according to the addition ratio of glutinous rice powder, viscosity of the G0 and G4 groups decreased according to the addition ratio of Cheongdung pumpkin, whereas they first decreased and then increased in the G8 and G12 groups. All groups showed increased viscosity whit more glutinous rice powder. For the sensory evaluation, P5G8 was mostly preferred in all aspects. P7G4 was superior in all aspects except for flavor. P10G4 scored the highest in all aspects except viscosity. For acceptance test, except for the control group, P7G4 whit added of 70% Cheongdung pumpkin, 30% sweet pumpkin and 4% glutinous rice powder was the most preferred in all aspects except color (gloss, viscosity, flavor, taste and overall quality).

${\beta}-carotene$ is present in carrots, pumpkins, and sweet potatoes. It suppresses many types of cancers by regulating cellular proliferation and apoptosis through a variety of mechanisms. However, the effects of ${\beta}-carotene$ on oral cancer cells have not been clearly established. The main goal of this study was to investigate the effects of ${\beta}-carotene$ on cell growth and apoptosis in oral cancer cells. Our results demonstrate that treatment with ${\beta}-carotene$ induced inhibition of cell growth, and that the effect was dependent on ${\beta}-carotene$ treatment time and concentration in KB cells. Furthermore, treatment with ${\beta}-carotene$ induced nuclear condensation and fragmentation in KB cells. ${\beta}-carotene$ promoted proteolytic cleavage of procaspase-3, -7, -8 and -9 with associated increases in the concentration of cleaved caspase-3, -7, -8 and -9. In addition, the level of cleaved PARP was increased by ${\beta}-carotene$ treatment in KB cells. These results suggest that ${\beta}-carotene$ can suppress cell growth and induce apoptosis in KB human oral cancer cells, and that it may have potential usefulness in anti-cancer drug discovery efforts.
