The objective of this article is to examine the possibility of 'story-telling' as united concept of causality and subjectivity through sequence combination, and the 'similarity' between object and image in fashion photographs making diversity of meanings. To analyze and investigate the research, as evidential data this paper used the photos of Steven Meisel from 2002 till 2007 Vogue published in Korea, U.S, and Italy, as well as other visual data like graphic collections, catalogs, art-related data and internet data. This research runs both theoretical and positive investigations to suggest the function of story-telling in the Process of opened-communicative roles of fashion photos. Thus this paper investigated Steven Meisel's storytelling in his fashion photos; short moment of event, continuity of time, compound of sequence, and complexity of viewpoint. This paper also studied the aesthetic characteristics of Steven Meisel's fashion photos as categories of overlapped meaning, arbitrariness of interpretation, exclusivity of message, and decoding. The research result suggests that clothing not only includes current age's value but also among social constitutions it includes multilateral characteristics. Ultimately this paper is also making meaning alive by cutting off the chain of 'firm' meanings of fashion photo. That seems like opening the opportunity for correctly understanding fashion's meaning which has the aspects of ambivalence of changing meanings and values by the motivation of context and text.

Centered on Kathleen Kye, a designer who conveyed messages on social issues through her dresses, and established her own identity, this study aimed to examine what theme, method of expression and inner meaning her 'statement' had, as a way of expressing a critical awareness. After reviewing discussions by Duggan G. G. as well as dictionary definitions, statement fashion design can be defined as a work or fashion shows containing a message of a designer who is free from a particular trend or consumerism in various social issues. Statement fashion designers give opposing messages on social issues through their fashion collections. As a result, research shows that contemporary statement fashion designers are expressing themes of a fashion systems, fetishism, body image, collision, environment, as well as the socially disadvantaged by appropriation, reuse, slogan, metaphorical pattern and performance. Satire, awakening, challenge and support can be derived from the inner meaning of contemporary statement fashion design. In terms of the theme, method of expression and inner meaning, this study showed that KYE collection of the designer Kathleen Kye expresses critical awareness on the modern society. Research findings reveal that KYE collection include the following themes: long-term youth unemployment, conflict collision in war or on the Internet, fetishism by youth in a get-rich-quick fever, environmental issue causing destruction of an ecosystem by decrease in bee population, school violence and the socially disadvantaged related to alienated immigrants. Also, as a method of expression themes, such as metaphorical patterns, were used. The patterns used images including a skeleton, gun, heart, rope, plaster, homeless box, bee, honeycomb, chain and a slot machine. On the other hand, the inner meaning of statement in KYE collection showed satire on social issues, awakening on social issues unrecognized by the masses, and support for the socially disadvantaged.

The objective of this study was to develop a fluorogenic real-time PCR-based assay for detecting and quantifying amounts of cow milk in cow/goat milk mixtures or goat milk products. In order to quantify the exact amount of cow milk in cow/goat raw milk mixtures and commercial goat milk products, it was necessary to achieve quantitative extraction of total genomic DNA from the raw milk matrix. Both mammalian-specific PCR and cow-specific PCR were performed. A cow-specific 252 bp band obtained from the raw cow milk and raw goat milk mixtures, commercial goat milk, and two goat milk powders was identified, along with the relationship between the cow milk amount and band intensity of the electrophoresis image. The detection threshold was found to be 0.1%. The expression of cow's 12S rRNA in the cow/goat milk mixtures, commercial goat milk, and two goat milk powders was identified. The expression quantity of the milk 12S rRNA increased with increasing ratios of the cow/goat milk mixtures. Using these calibrated relative expression levels as a standard curve in the cow/goat raw milk mixtures, the contents of cow milk were 1.8% in the commercial goat milk, 9.6% in goat milk powder A, and 11.6% in goat milk powder C. However, cow milk was not detected in goat milk powder B.

Content-adaptive steganography methods embed secret messages in hard-to-model regions of covers such as complicated texture or noisy area. Content-adaptive steganalysis methods often need high dimensional features to capture more subtle relationships of local dependencies among adjacent pixels. However, these methods require many computational complexity and depend on the location of hidden message and the exploited distortion metrics. In this paper, we propose an improved steganalysis method for content-adaptive steganography to enhance detection rate with small number features. We first show that the features form the difference between DCT coefficients are useful for analyzing the content-adaptive steganography methods, and present feature extraction mehtod using first-order Markov probability for the the difference between DCT coefficients. The extracted features are used as input of ensemble classifier. Experimental results show that the proposed method outperforms previous schemes in terms of detection rates and accuracy in spite of a small number features in various content-adaptive stego images.

This study analyzed the expressive phenomenon of a blurred boundary in fashion jewelry focused on the relationship between fashion jewelry and costume or fashion jewelry and body. The method of this study was to analyze recent documentaries about jewelry theories in regards to 607 cases of fashion jewelry design in fashion books, fashion magazines, fashion internet sites from 2000 to 2014. The results were: First, phenomenon of blurred boundary between fashion jewelry and costume was expressed in a see-through wear form made of luxury material (gold and diamond) or paste material, a similar form (like fashion accessories made of crystal, bids, and gold chain), an integration of fashion accessories and jewelry, and an attached jewelry on fashion accessories. It reflected a rearrangement of conventional relationships, a blurred relation of function and meaning, dissolution of jewelry form stereotypes, jewelry styling, a harmony of function and decoration, and an alteration to the central role of a fashion image. Second, the phenomenon of a blurred boundary between fashion jewelry and body was expressed in a body organ wrapping, body surface adhesion and sculptural jewelry based on body pose. It reflected a separation from conventional space of jewelry expression, a realization of mystery and fantastic, an expression of new body surface and a blurred boundaries of fashion jewelry and body art. Aesthetic characteristics were analyzed into metaphor and integration by separation from the conventional relationship of fashion jewelry and costume or fashion jewelry and body.

Objectives : Brain inflammation early activates the microglia and activated microglia secrete a variety of pro-inflammatory cytokines. Kaempferol, which is a flavonoid in Cuscutae Semen, shows a wide range of physiological activities, including neurons protection and anti-inflammatory actions through inhibition of pro-inflammatory mediators. The present study examined the modulatory effect of kaempferol on cytokines [tumor necrosis factor- alpha ($TNF-{\alpha}$), interleukin-1beta ($IL-1{\beta}$) and interleukin-6 (IL-6)] and cyclooxygenase-2 (COX-2) mRNA expression and microglia activation in the brain tissue of the mouse. Methods : Kaempferol was administered orally three doses of 10, 20 and 30 mg/kg respectively, once 1 hour before the lippolysaccharide(LPS) (3 mg/kg, i.p.) injection. Brain tissue was removed at 4 hours after LPS injection. Cytokines and COX-2 mRNA expression in the brain tissue was measured by the quantitative real-time polymerase chain reaction (PCR) method. Iba1 expression was calculated by western blotting method. Microglia was observed with immunohistochemistry. Immunohistochemistry stained microglia was analyzed by using ImageJ software. Results : Kaempferol 20 and 30 mg/kg was significantly attenuated the expression of $TNF-{\alpha}$, $IL-1{\beta}$ and IL-6 mRNA. Kaempfrol 10, 20 and 30 mg/kg significantly attenuated COX-2 mRNA expression in the brain tissue. Kaempferol 30 mg/kg significantly suppressed the increase of Iba1 protein expression by LPS. Kaempferol 30 mg/kg significantly decreased the number of microglia in the cerebral cortex and the number and cell size of microglia in the hypothalamic region and the area percentage of ionized calcium binding adaptor molecule 1(Iba1)-expressed microglia in the hippocampus. Conclusions : This results indicate that kaempferol plays an anti-inflammatory role in the brain.

Objectives : Adipogenesis was defined as a differentiation process of preadipocytes into the adipocytes. Thus, to control of this process can be one of the most important strategies to prevent obesity. Korean ginseng(Panax ginseng C.A. Meyer) is one of the most widely used medicinal herbs. Although multiple biological activities of Korean ginseng, particularly ginsenosides, have been known, the anti-adipogenic role and function of polysaccharides from Korean ginseng are still unclear. In this study, we examined anti-adipogenic activity of polysaccharides and its molecular basis mechanisms are further investigated.Methods : The cytotoxicity of KGP in 3T3-L1 was evaluated by MTT assay. Anti-adipogenic effect of KGP was examined by Oil Red O (ORO) staining and microscopy observation in 3T3-L1 mature adipocytes. The mRNA expression levels of adipogenic transcriptional factors were analyzed by reverse transcription-polymer chain reaction (RT-PCR). To elucidate the adipogenic molecular mechanism of KGT, SB431542 (TGF-β specific inhibitor) was used.Results : We found that polysaccharides showed no effect on the viability of 3T3-L1 preadipocytes. Dose dependent inhibitory effect of polysaccharides on 3T3-L1 adipogenesis was observed as judged by ORO staining and microscopic image analysis. To obtain further mechanistic insight into anti-adipogenic function of polysaccharides, we then tested the effect of polysaccharides treatment on the adipogenic marker genes. The mRNA expressions level of C/EBPα, PPARγ, C/EBPβ, and fatty acid synthase (FAS) were dose-dependently inhibited by KGP treatment in 3T3-L1 mature adipocytes.Conclusions : In conclusion, these findings suggest that the KGP could be used in treatment of obesity and overweight related diseases.

The modulation transfer function (MTF) in a camera system is a measurement of how well the system will faithfully reproduce the original scene. The electro-optical camera system consists of optics, an array of pixels, and an electronics which is related to the image signal chain. The system MTF can be cascaded with each element's MTF in the frequency domain. That is to say, the electronics MTF including the detector MTF can be recalculated easily by the acquired system MTF if the well-known test optics is used in the measuring process. A Time-Delay and Integration (TDI) detector can make a signal increase by taking multiple exposures of the same object and adding them. It can be considered the various methods to measure the MTF of the TDI camera system. This paper shows the actual and practical MTF measuring methods for the detector and electronics in the TDI camera. The several methods are described according to the scan direction as well as the TDI stages such as the single line mode and the multiple-lines mode. The measuring is performed in the in the static condition or dynamic condition to get the point spread function (PSF) or the line spread function (LSF). Especially, the dynamic test bench is used to simulate on track velocity to synchronize with TDI read out frequency for the dynamic movement.

Cyclooxygenase(COX-2) is an inducible enzyme that catalyzes the synthesis of prostaglandins (PGs) from arachidonic acid. Over-expression of COX-2 has been reported to be associated with progressive hepatic fibrosis in chronic hepatic C infection and rat liver fibrosis induced by carbon tetrachloride($CCl_4$). Recently, it is well known that mast cell products can stimulate the proliferation of hepatic stellate cells and key players in liver fibrosis. But little is known regarding their role in $CCl_4$-induced liver fibrosis in rat. Our aim was to investigate the relation between COX-2 expression and mast cells during liver fibrosis after $CCl_4$ treatment. Thirty Wistar rats were divided into five groups (non-treated 0, 2, 4, 6 and 8-week after $CCl_4$-treatment). Reverse transcription polymerase chain reaction (RT-PCR) and immunohistochemistry were used to assess the expression of ${\alpha}$-smooth muscle actin (${\alpha}$-SMA), collagen-1 and COX-2 in liver tissue from $CCl_4$-treated rats. The density of collagen and mast cells were determined using a computerized image analysis system in liver sections stained with picrosirius red and toluidine blue, respectively. The expression levels of ${\alpha}$-SMA, collagen-1 and COX-2 mRNA were significantly higher at 2 wk in $CCl_4$-treated groups than non-treated group. The number of mast cells in liver tissues increased gradually from 2 wk to 6 wk depending on the fibrosis severity but decreased abruptly at 8 wk. The significant increase of collagen-1 and ${\alpha}$-SMA mRNA expression in $CCl_4$-treated rats was continued until 6 wk while the COX-2 mRNA was significantly decreased at 8 wk. These results suggest that increased mast cells are closely associated with COX-2 over-expression during hepatic fibrogenesis of $CCl_4$-treated rats.

This study surveyed university students in the Seoul and Kyonggi areas regarding their recognition and satisfaction of high quality ice creams. In terms of their preference for high quality ice creams, 152 (40.2%) answered "moderate", and 200 (52.9%) answered "likeable" or "very likeable", showing a very high preference. Ice cream was most often consumed as a snack (30.0%). The preferred food materials in combination with ice cream were fruits (32.8%), followed by chocolates (28.8%), dairy (15.6%), and nuts (7.7%). Many students viewed ice cream as an unhealthy food (46.8%), and the most frequent reason for using a selected brand was "taste" (46.6%), followed by "variety" (16.1%), "advertisement" (14.1%), and "operating of chain shop" (10.3%). In terms of overall satisfaction, 41.4% answered "somewhat satisfactory" or "very satisfactory", and only 9.8% answered "somewhat unsatisfactory" or "very unsatisfactory". The satisfaction construct was divided into nine sectors: nutrition, low calorie, functional, taste, color, variety, high quality, hygiene, and value. When these sectors were analyzed, "variety" was "somewhat satisfactory" or "very satisfactory" (74.2%), and "value" was "somewhat unsatisfactory" or "very unsatisfactory" (47.5%). In the analysis of satisfaction factors according to sectors, the Cronbach's $\alpha$ value related to nutrition was 0.755, that of preference was 0.830, and that of image was 0.661.
