This is a basic research aimed at enhancing a brand image by unifying color images of a brand at both online and offline stores. h survey was conducted on color images of online and offline stores to measure the level of consistency between consumers' perception of the color image and the brand's color strategy. A brand preference survey was also performed to shed light on the relationship between the brand preference and the consistency of color images at online and offline stores. This study is committed to building an effective color strategy, based on the brand strategy, through web color planning that is consistent with the offline color image. This paper started with a specific purpose of devising solutions in regard to the prior study, entitled 'Study on Color Strategies in Brand Coffee', which recognizes the need for consistent color images, or integrated color strategies, in online and offline stores. I specifically took the approach of looking at color planning in the stage of designing a website. Two standards were used to analyze emotional and functional aspects of color images: color grading by I.R.I and five communicators of color information by Rouge. Direct visits were made to the offline stores for surveys to address the shortcomings of the prior study, in which offline stimuli were limited to printed materials. The direct visits enabled a study of an overall color image of the offline stores, while providing a set of substantial and specific guidelines for designing colors for a website. I hope this study goes a long way toward enhancing the level of consistency between online and offline color images based on the brand's unique color strategy, and thereby improving the overall level of brand image.

In the present study, we assessed whether the extracts of Codonopsis lanceolata and fermented C. lanceolata posses the cognition-enhancing effect in rats with impaired learning and memory by scopolamine treatment (1 mg/kg, i.p.), an antagonist of muscarinic acetylcholine (ACh) receptor. The fermented C. lanceolata extract (333, 667 mg/kg) significantly reversed the scopolamine-induced cognitive impairments in the passive avoidance test (p<0.05). Moreover, fermented C. lanceolata extract (333 mg/kg) also improved escape latencies in training trials of Morris water maze test (p<0.05). The water extract of fermented C. lanceolata showed significant anti-amnestic and cognitive-enhancing activities related to the memory processes, and these activities were parallel to treatment duration and dependent of the learning models.

Peppers (Capsicum annuum L.) are a rich source of phytochemicals including polyphenolics, flavonoids, capsaicinoids and ascorbic acid. Capsaicinoids are a group of 12 or more related alkaloids responsible for the pungent sensation in the fruits of the genus Capsicum. Ascorbic acid is another functional and nutritional constituent of peppers. In this study, the contents of two major capsaicinoids (capsaicin and dihydrocapsaicin) and ascorbic acid in 131 pepper breeding lines were quantified by HPLC. In 131 pepper breeding lines, capsaicin and dihydrocapsaicin contents were in the range of 0.0 to 219.6 and 0.0 to 110.8 mg/100 g, respectively. The breeding lines with higher capsaicin content contained higher dihydrocapsaicin content as well. Ascorbic acid contents were 264.9 to 1695.5 mg/100 g for the 131 pepper breeding lines. The analytical method validation parameters including accuracy, repeatability, and reproducibility were calculated to ensure the method's validity. This study provides basic information to plant breeders and biotechnologists who are planning to breed genotypes with high content of phytochemicals.

To elucidate the biochemical etiology. 1) plasma dopemine-beta-hydroxylase activity was measured and 2) the correlation between age and DBH activity was examined in 30 Tourette's disorder, 19 chronic motor tic disorder, and 24 controls. The results are summarized as follows : 1) The mean plasma DBH activity in Tourette's disorder was significantly elevated compared to normal groups, but significant differences in DBH activity between Tourette's disorder and chronic motor tic disorder, and between chronic motor tic disorder and normal control group were not found. 2) In all three groups, the significant positive correlations between age and plasma DBH activity found. These findings support the hypothesis of a possible involvement of brain catecholamine dysfunction in the production of Tourette's disorders, and this dysfunction might be due to the increased dopaminergic and decreased noradrenergic function. Future research should be focused on the mechanism of functional abnormalities of DBH.

The purposes of this study is to discuss and analyze the effect on the recovery from cut in sciatic nerve. This study used 9 weeks male rats of Sprague-Dawley family. Rat in groups 4 were treated with pulsed therapeutic ultrasound for 3 minutes. 3 times weekly at 3MHz respectively (intensity; $0.2W/cm^2,\;0.5W/Cm^2,\;10W/cm^2$); rat in group 1 received placebo ultrasound. In addition, changes of serum aspartate amino-transferase(AST) and creatine phosphokinase(CPK) levels were also demonstrated with diameter of individual muscle fasciculate and number of muscle fiber in each of three types of muscles located in gastrocnemius, soles. The results of comparing the changes in groups are as follows; 1. We found out that hypertrophic epineurium was present in sciatic nerve injured ultrasound treatment of groups. 2. In the gastrocnemius morphological investigation of the group I (control group), severe muscle atrophy were observed at the 7th days of the sciatic nerve injury. however, muscle atrophy of the group IV ($1.0W/cm^2$) were slightly recovered at the 14th days after treatment ultrasound. At the 28th days, muscular fibers were formed in polygon and were significantly recovered. 3. C-fos immunoreactive of the group II ($0.2W/cm^2$), III ($0.5W/cm^2$) were remarkably increased at the 1th day after treatment of ultrasound. Group IV were markedly deceased. 4. Brain-Derived Neurotrophic Factor(BDNF) immunoreactive of the group II, III were increased after 7 days of the sciatic nerve injury. Group IV were markedly increased from 14th days to 28th days after treatment of ultrasound. 5. A significant increase of serum AST levels were demonstrated in control group. However, serum AST levels of massage groups were significantly decreased compared to that of control group in followed order ; ($0.2W/cm^2<0.5W/cm^2<1.0W/cm^2$). 6. A significant increase of serum CK levels were demonstrated in control of group. However, serum CK levels of massage groups were significantly decreased compared to that of control group in followed order ; ($0.2W/cm^2<0.5W/cm^2<1.0W/cm^2$). The above results suggest that ultrasound treatment after peripheral nerve injury might reduce noxious stimuli, facilitate nerve recovery and effective in the functional improvement delaying muscle atrophy or degeneration.

Biomass changes, net primary production and transfer dynamics of dry matter in four subtropical humid montane grasslands at Ebbenadu, Korakundah, Thiashola and Wenlockdown in Nilgiri Biosphere Reserve (NBR), the Western Ghats, India, were investigated. Despite the early report of a higher density and dominance of $C_4$ species over $C_3$ species in these grasslands, no functional study of matter production had previously been carried out. Therefore, in order to determine the roles played by these two groups of species, the present study was attempted. The study revealed that the dry matter and net primary production contributed by $C_4$ species were much greater than those of its $C_3$ counterpart in all the grasslands. The turnover rate of aboveground dry matter for both $C_3$ and $C_4$ species was generally rapid, whereas it was slow for belowground parts, and litter components of $C_3$ and $C_4$ species together. In all grasslands, generally about 60% and 10% of the input were channeled to aboveground and belowground parts, respectively, by the $C_4$ species, whereas the $C_3$ species transferred only about 22% and 8% of dry matter to aboveground and belowground parts, respectively. The total disappearance of dry matter was 2.73, 2.10, 3.19, and $1.96\;g\;m^{-2}\;day^{-1}$ in Ebbenadu, Korakundah, Thiashola and Wenlockdown grasslands, which was 48.83%, 44.30%, 54.81%, and 41.09% of the total input, respectively, in these grasslands. This resulted in a considerable surplus dry matter production in all the grasslands studied. This balance sheet of dry matter in community function indicates that all the four studied grasslands were supporting the existing wild animals adequately in terms of pasture supply. The study further revealed that the stronger establishment of $C_4$ species rather than their $C_3$ counterparts, in terms of higher density and dominance, has driven them to play major roles in matter dynamics and system transfer functions in all the four grasslands studied. This fact evidenced that pasture from $C_4$ species for wild animals was determined to be higher in comparison to that of $C_3$ species.

Photographs and illustrations are integral parts of current science textbooks' inscriptions. This study analysed and compared the function and structure of photographs and illustrations used in high school earth science textbooks of the 6th and 7th national curriculum. The findings of the function analysis showed that 'illustrative' function was far superior to other functions in terms of frequency and ratio. The illustrative function varied more in the 7th curriculum textbooks, especially in earth science I. 'Explanatory' and 'complementary' functions, which were relatively ignored in the 6th curriculum, significantly increased in the 7th curriculum textbooks. 'Decorative' function increased on the whole. The results of the structure analysis revealed that indexical reference remarkably decreased in the 7th curriculum textbooks, which means the retrogression of co-deployment with main text. 'Multiple' organized photographs and illustrations significantly increased in the 7th curriculum textbooks, while 'pair' and 'series' organization did not show an increase at all. It was suggested in this study that 'inquisitive' function and 'complementary' organization should be supplemented in terms of both function and structure. Moreover, the functional and structural aspects of scientific inscriptions including photographs and illustrations should be utilized by the certification criteria of science textbooks.

This study aims to analyze the 'Standard Drawings for School Facilities' issued by Seoul Education Committee in 1975 because it is the early example for middle school architecture. The results of this study are summarized as follows 1) In general trend of single-corridor type block plan, there are also changes in floor plan like no-corridor type block plan, $9.9{\times}6.6m$ classroom unit for the better daylight condition, built-in storage for students. 2) As for elevation design, it is characterized as daylight-oriented, functional exterior for without making full use of design elements. 3) Standardized dimensions are used as a rule in the height of story, ceiling, window sill and etc. Transitional characteristics of the early RC school architecture are found in exposed ceiling, incomplete insulation structure and mixed use of wood framed floor of earlier type. 4) Contrast to main school building, gymnasium shows the intend to express the symbolism of school architecture with diverse elevation design elements and the plasticity of building mass. 5) Separated plan of toilet and night-duty building also show the transitional characteristics. As conclusion, though showing the stereotyped school architecture, on the other hand, 'Standard Drawings for School Facilities' (1975) makes it possible to see the way of coping with the demands for school architecture in that time and the transition of school architecture. This is the main value of it as the material for the studies related to the history of educational facilities.

A recent study reported that Pleurotus ostreatus has the potential to be used as a ${\beta}-glucan-based$ cream for supportive complementary therapy of atopic dermatitis. KH054 is a new herbal prescription consisting of P. ostreatus and Panax ginseng. The effects of atopic dermatitis-induced materials on the expression of cytokine genes in human monocytes (THP-1, EoL- 1) have been examined. Some reports demonstrated that P. ginseng augments the activity of natural killer cells, which plays an important role in innate immunity against infection and tumor development. Monocyte chemotactic protein 1 (MCP-1), interleukin (IL)-6, and IL-8 have important roles in mediating the infiltration of various cells into the skin of atopic dermatitis and psoriasis. The present study investigated whether KH054 on induced IL-6, IL-8, and MCP-1 secretion by house dust mite (Dermatophagoides pteronissinus) in THP-1 (human acute monocytic leukemia) and EoL-1(Human eosinophilic leukemia) cell. D. pteronissinus functions in the pathogenesis of allergic diseases, including atopic dermatitis and asthma. The inhibitory effect of KH054 on the induction of IL-6, IL-8, and MCP-1 secretion by D. pteronissinus extract in THP-1 and EoL-1 cells was examined. KH054 potently suppressed the elevated production of IL-6 and IL-8 induced by D. pteronissinus treatment in THP-1 and EoL-1 cells. Based on the present results, KH054 may be useful for developing functional foods to treat atopic dermatitis.

The aim of this study was to investigate the anti-inflammatory effect of Sargassum miyabei Yendo ethanol extract (SMYEE) using RAW 264.7 cells and croton oil-induced Balb/c mice. SMYEE inhibited the production of pro-inflammatory cytokines [interleukin (IL)-6, tumor necrosis factor $(TNF)-{\alpha}$, and $IL-1{\beta}$] and nitric oxide in lipopolysaccharide (LPS)-induced inflammatory response. In addition, SMYEE suppressed the expression of inducible nitric oxide, cyclooxygenase-2, and nuclear factor-kappa B. Further, SMYEE inhibited the expression of mitogen-activated protein kinases (MAPKs), such as extra cellular signal-regulated kinase 1/2, p38, and c-Jun N-terminal kinase. In ear edema test, edema formation in the SMYEE treatment was lower than that in the positive control and was similar to that in the prednisolone treatment group. Photomicrographs of mice ear tissue showed a reduction in dermal thickness and number of infiltrated mast cells. Therefore, our results indicate that SMYEE exerts an anti-inflammatory effect via inhibition of nuclear factor ${NF}-{\kappa}B$ and MAPK activation and can be used as a natural source of anti-inflammatory compounds.
