The effect of water temperature, salinity and water column nutrient contents on pigment composition and concentration of purple lavers were studied at the main purple lavers production areas in Southwestern coast of Korea, during January to March, 2011. Water temperature was between 3.0 and $11.3^{\circ}C$. Salinity range was between 32.7 and 34.7, those were lower St. 1 and St. 6, which were at close to the seashore. Water column dissolved inorganic nitrogen (DIN), dissolved inorganic phosphorus (DIP) and silicate concentrations were $1.73{\sim}12.84{\mu}M$, $0.07{\sim}0.67{\mu}M$ and $4.93{\sim}18.29{\mu}M$, respectively. Chl a concentration was between 0.41 and $9.14{\mu}g\;L^{-1}$, and it was the highest at St. 1 during January. Photosynthetic pigment of fucoxanthin was dominant at all sites, which showed its highest concentration ($0.06{\sim}3.41{\mu}g\;L^{-1}$) at St. 1 on January. Water column DIN concentration was higher at January during low salinity period at all sites, but it was low at St. 1. Photosynthetic pigment of Chl a, PE and PC concentration of porphyra blades was between $1,173{\sim}8,124{\mu}g\;DW\;g^{-1}$, $3,281{\sim}10,076{\mu}g\;DW\;g^{-1}$, $388{\sim}1,346{\mu}g\;DW\;g^{-1}$, respectively. The concentration was relatively high at the St. 2 and St. 3. The pigment concentration of porphyra blades was higher at only Porphyra yezoensis was cultured than at Porphyra yezoensis and Porphyra seriata were cultured. The pigment concentration of porphyra blades was higher at St. 2 and St. 3 in only Porphyra yezoensis was cultured. This study shows that pigment concentration of porphyra blades may depend on habitat environment and culture methods.

With ${15}^N$ labeling under split roots system of winter rye (Secale cereale L.) and forage rape (Brassica napus L.) grown at $5^{\circ}C$ and $25^{\circ}C$, the N flows were respectively quantified to investigate the transport of newly absorbed nitrate-N in whole plant level at low temperature. Comparing with $25^{\circ}C$ culture condition, the total absorbed nitrate-N content at $5^{\circ}C$ decreased to 59.3% and 27.1% in winter rye and forage rape during 9 days. About 2.5% and 7.6 % of nitrate-N were transported into roots, respectively, in winter rye and in forage rape at $25^{\circ}C$. These proportions increased at $5^{\circ}C$ to 3.8% and 10.9%, respectively. Total N contents transferred by xylem in winter rye grown and forage rape grown at $25^{\circ}C$ during were 55.9 and 54.4 mg N/plant, respectively. xylem flows at $5^{\circ}C$ were 60.4% and 28.8% lower than at $25^{\circ}C$ for winter rye and forage rape. These valves represented that averagely 96.8 % and 90.8% of total absorbed nitrate-N were transferred to leaves in winter rye and forage rape during 9 days. Phloem flows were the smallest among other N flows and were much less influenced by temperature treatment for two species examined. About 2.5% and 0.5% of absorbed N were recycled into roots by phloem transport at $25^{\circ}C$, respectively, for winter rye and forage rape. These proportions increased to 5.2% and 0.9% at $5^{\circ}C$.

This study researched the effects of cooking methods on phytochemical-enriched thin rice porridge (RP) of three colors (red, yellow, and green). Each of the RPs was prepared by three cooking methods and retorted through two-steps (step 1, at $80^{\circ}C$ for 15 min; step 2, at $82^{\circ}C$ for 25 min) for pasteurization. Cooking method (CM) 1 involved heating a mixture of all ingredients while CM 2 involved addition of apple/beet (AB, red), sweet-pumpkin/cabbage (PC, yellow) or vitamin/pear (green) while heating rice flour and glutinous rice flour. CM 3 involved mixing pre-cooked fruits and vegetables with cooked thin RP. The viscosity of RP prepared by CM 1 was lower than those of other RPs (P<0.05). The result of colorimetric a value show that red and green color of AB and VP prepared by CM 2 and CM 3 were most vivid. Contents of phytochemicals and antioxidants were higher when RP was prepared by CM 2 and CM 3 compared to CM 1. ${\Delta}E$ values of PC showed no significant difference before and after pasteurization, whereas AB and VP were significantly different (P<0.05). Antioxidant activity after retorting was not significantly different from those of un-retorted RPs. The results of color, phytochemical content, and antioxidant activity show that CM 2 or CM 3 were considerably better than CM 1, whereas cooking method had no effect after two-step retorting. Therefore, uncomplicated cooking method such as CM 1 or CM 2 are suited for commercial production of RPs.

The functions of urban open space, which embraces community revitalization, are diverse. It is the means of public healthcare, learning centers for children, hub of arts and cultural programs, as well as promoter of urban tourism. However, in-depth discourse and research on the topic of urban open spaces has been limited so far. Hence, this study aims to investigate the motivations and satisfaction of visitation based on four representative waterfront open space in Seoul; Cheongyecheon Waterfront, Seoul Forest Park, Seonyudo Park and Banpo Hangang Park. The methods of study are literature review, observation investigation, and questionnaire survey. The findings are analyzed through the Exploratory Factor Analysis, Reliability Analysis, ANOVA Analysis and Regression Analysis by SPSS 18.0. The results of the study are as follows. First, urban waterfront open spaces in Seoul has 5 factors of visitor motivation; community amenity, nature access, cultural and educational assets, aesthetic enjoyment, and lastly means of escape. Second, factors of recognizing urban waterfront open spaces as community amenity and nature access indicate meaningful differences in visitor's perception by spatial characteristics. Third, distances between the destination and the visitor's residence influence significantly their perceived motivation. Close-range visitors perceived nature access as a principal factor, whilst medium to long-range visitors perceived visitation for aesthetic purposes more importantly. Lastly, the will to escape was shown as the influential factor in visitor satisfaction. Visiting open spaces for the enjoyment of nature and aesthetic purposes were factors that also closely relate to visitor satisfaction. In addition, it was found that there are different visitor motivations that influence visitor satisfaction in accordance with the spatial characteristics of each open space. In summary, it can be said that urban waterfront open space is a hybrid space connected to various types of urban contents beyond daily experiences. It was found that several visitor motivations including community development, design aesthetics, education and culture, entertainment, enjoyment of natural landscape, and relaxation, affect the overall satisfaction of the visiting experience. It is anticipated that the results of the study will be used by the local government in setting up strategies for the creation and management of successful urban waterfront open space, and for those involved in planning and design act as a starting point for spatial programming and amenities arrangement in accordance to the city's tourism and urban marketing approach.

With the awareness that Sinyeongwol Sipgyeong(ten scenic spots in Yeongwol) were designed too hastily and only for PR purposes after the change in the tourism environment, this paper indicates that most tourism and culture sources in Yeongwol are related to King Danjong, the sixth king of the Joseon Dynasty. This study proposes a 'Storytelling Plan' for the landscape content called 'Cultural Landscapes - Yeongwol Palgyeong(eight scenic spots in Yeongwol)' after reviewing types and content of Yeongwol Palgyeong through the halo effect of the well-known sad history of King Danjong and the cultural value of Yeongwol. The significance of the unity of the historic site and neighboring landscape is focused on by investigating the anaphoric relations between cultural landscape texts('Yeongwol Palgyeong') and historic content(the sad history of King Danjong). For this, the cultural lnddscape of Yeongwol has been framed and layered to make spatial texts. To emphasize the 'Telling' as well as the 'Story,' interesting episodes have been reviewed to discover a motive. To diversify the 'Telling' methods, absorptive landscape factors have been classified as 'Place,' 'Object' and 'Visual Point.' In addition the storytelling of Yeongwol Palgyeong was examined in consideration of the story and background of 'Yeongwol Palgyeong - Sad Story of King Danjong' and the interaction of a variety of cultural content by suggesting micro-content such as infotainment and edutainment as absorptive landscape factors. In order to make the storytelling plan available in practice as an alternative plan for Yeongwol Tourism, a visual point should be properly set to make the landscape look sufficiently dynamic. In addition, real landscape routes and narration scenarios should be prepared as well. Professional landscape interpreters who are well informed of the natural features of Yeongwol and the history of King Danjong should be brought into the project, and Internet and digital technology-based strategies should be developed.

Conger eel (Conger myriaster) is used as a well-being food in the foodservice industry in Korea. We analyzed not only the proximate composition but also the taste components affecting conger eel, which are fatty acids, nucleotides, amino acids, etc. Concerning the composition, the crude lipid was the lowest in summer at 3.2%, which is considered due to spawning period. The major fatty acids were $C_{16:0},\;C_{16:1},\;C_{18:0},\;C_{18:1},\;C_{20:5},\;and\;C_{22:6}$. The $C_{18:1}$ content was the highest among the fatty acids and the content varied between 36.76 and 45.11% by season. Seasonal change in the content of poly-unsaturated fatty acids was increased from spring to winter in conger eel. Among the nucleotides, the contents of IMP (3.617$\sim$5.524 $\mu$mol/g) and Hx (0.913$\sim$2.238 $\mu$mol/g), which is closely related to taste, and the concentrations of IMP and Hx were the highest (7.219 $\mu$mol/g) in winter, and HxR (0.625$\sim$1.652 $\mu$mol/g) was higher than ATP (0.058$\sim$0.083 $\mu$mol/g), ADP (0.145$\sim$0.161 $\mu$mol/g), and AMP (0.166$\sim$0.179 $\mu$mol/g). In conger eels, the major total and free amino acids were glutamic acid (14,178.7$\sim$7,802.6 mg%), aspartic acid (4,669.2$\sim$8,259.0 mg%), lysine (4,198.3$\sim$7,540.8 mg%), leucine (3,843.6$\sim$6,782.1 mg%), and histidine (199.6$\sim$644.4 mg%), glycine (94.8$\sim$152.2 mg%), alanine (35.3$\sim$71.2 mg%), glutamic acid (44.1$\sim$70.6 mg%), respectively, but the concentration of amino acids was different by season. The content of free amino acids, which is related to the taste component, was detected as high in summer and winter at 1179.2 and 1,605.2 mg%, respectively.

Drought is a major obstacle to high agricultural productivity, worldwide. In drought, it is usually presented by the simultaneous action of high temperature and drying. Also there are negative effects of plant growth under drying conditions. In this study, the effect of Bacillus velezensis YP2 on plant growth-promotion and soil drying stress tolerance of kale plants, Brassica oleracea var. alboglabra Bailey, were investigated under two different conditions; greenhouse and field environments. Root colonization ability of B. velezensis YP2 was also analysed by using plating culture method. As a result of the greenhouse test, the YP2 strain significantly promoted the growth of kale seedlings in increasement of 26.7% of plant height and 142.2% of shoot fresh weight compared to control. B. velezensis YP2 have the mitigation effect of drying injury of kale by decreasing of 39.4% compared to control. In the field test, B. velezensis YP2 strain was also found to be effective for plant growth-promotion and mitigation of drying stress injury on kale plants. Especially, relative water contents (RWC; %) were higher in B. velezensis YP2 treated kales than in control at 7, 10, 14 day after non-watering. The root colonization ability of YP2 strain was continued at least for 21 days after soil drenching treatment of B. velezensis YP2. Our result suggested that enhancement of plant growth and drying injury reduction of kale plants were involved in kale root colonization by B. velezensis YP2, which might be contributed to increasing water availability of plants. Consequentially, the use of B. velezensis YP2 might be a beneficial influence for improving productivity of kale plants under drying stress conditions.

This experiment was carried out to study the effects of nitrogen concentration of cultural solution, Rhizobium inoculation, and planting density on the growth and yield of soybean cultivars, Hwanggeumkong, Jangbaegkong, Paldalkong, Clark, and non-nodulation isoline of Clark. Rhizobium inoculation increased the stem length, particularly in Hwanggeumkong, Jangbaegkong, and decreased it significantly in non-nodulation Clark. Stem length was increased by the increase in nitrogen fertilization by the 195ppm level and decreased by the increase in plant population density. Rhizobium inoculation also increased the shoot dry weight, but significantly decreased it in non-nodulation Clark. As nitrogen concentration in the cultural solution increased the shoot dry weight decreased in Jangbaegkong and paldalkong. However, the shoot dry weight was decreased by the increase in plant population density. Rhizobium inoculation and the increase in nitrogen concentration of cultural solution increased the ratio of shoot dry weight to root weight. The Rhizobium inoculation and the increase in nitrogen concentration of cultural solution increased the grain yield per pot in Hwanggeumkong and paldolkong, While non-nodulating Clark showed significant decrease in grain yield. Grain yield per pot was also increased by the increase of plant population density. Grain yield was significantly correlated with shoot dry weight, nodule number, and nitrogen content of the soybean plants. The correlation between nitrogen contents of the soybean plants and stem length, shoot dry weight, and nodulation was significant. The allantoin-N content in stem was also significantly correlated with nodulation.

In animation, 'laughter' is an important factor for the fun. Dreamworks' animation is a successful popular animation. It has four series and spin-off animations, and settled as a successful case that created fun with strategic use of parody throughout the productions. Most preceding studies on this animation have focused on its humor, parody, and satire. However, not many studies have discussed its independent comedy as a piece of animation that satisfies the needs of public. This study considered that viewers' desire to watch an animation comes from their fantasies to discuss the comedy of based on its animated characters. Animated characters communicate with the public with wits that ignore the rules of reality. The characters that do not exist in reality are created and animated to turn the world of reality upside down. The comedy in comes from the entertaining deformation of the society's fixed ideas and prejudices. It is a fun variation of the ideology behind fairy tales created by the Disney animations to challenge Disney in the animation market in reality, and twisted the world of fairy tales in the story to quench the thirst of the public. 'Shrek', a monstrous character, stands in the center of the story. A monstrous character that always played an anti-role has become the main character to break the rule of fairy tales. This is the subjectivation of anti-character. Second, it is a new anti-character with an exaggerated and distorted body. Lord Farquad, who looks abject compared to the monstrous character for a person with so much power and ambition, brings laughter. Third, it is the variation of various characters from fairy tales. The conventional fairy tale characters, both animals and non-living things, come out of the box and appear as humorous characters that bring life to the story. uses comedy characters in the process of reinterpreting the fixed ideas, prejudices, and ideologies of the real world created by fairy tales. I hope that it helps Korean animations establish a successful format for creating characters that bring life to the stories.

Three mushroom mycelia, Ganoderma lucidum, Hericium erinaceum, and Phellinus linteus, were separately diluted with the natural culture media Acanthopanax senticosus. Solid-state fermentation was used to produce three different A. senticosus-fermented mushroom mycelium groups: G. lucidum mycelia, H. erinaceum mycelia, and P. linteus mycelia. The resulting mycelia were analyzed to assess their efficacies as health functional foods. Optimized fermentation conditions were determined by considering the density and growth speed of mycelia in each A. senticosus-fermented mushroom mycelium group. The cultured mushroom mycelia under the optimized conditions were extracted using water and 70% ethanol. Extraction was followed by filtration, concentration and freeze-drying to produce extract powder of A. senticosus-fermented mushroom mycelia: Water extracts (FM-5111, FM-5121, and FM-5131) and 70% ethanol extracts (FM-5112, FM-5122, and FM-5132). Analysis of extract powder of A. senticosus-fermented mushroom mycelia was performed using the maker compounds eleutheroside B and eleutheroside E. Analysis of ${\beta}$-glucan contents was performed by enzymatic procedures.
