As the number of IPs and the communication volume among them have constantly increased, on-chip crossbar network is now the most widely-used on-chip communication backbone of contemporary SoCs. The on-chip crossbar network consists of multiple crossbars and the connections among the IPs and the crossbars. As the complexity of SoCs increases, it has also become more and more complex to determine the topology of the crossbar network. To tackle this problem, this paper proposes an on-chip crossbar network topology method for application-specific systems. The proposed method uses mixed integer linear programming to solve the topology synthesis problem, thus the global optimality is guaranteed. Unlike the previous MILP-based methods which represent the topology with adjacency matrixes of IPs and crossbar switches, the proposed method uses the communication edges among IPs as the basic element of the representation. The experimental results show that the proposed MILP formulation outperforms the previous one by improving the synthesis speed by 77.1 times on average, for 4 realistic benchmarks.

This study provides suggestions of cultural product design contents by using the cloud-shaped gong in traditional temple culture in order to find a high value-added approach. The research herein is part of cultural design contents projects embedded with the spiritual value and symbolic connotation of temple culture. This would be meaningful to enhance its degree of utilization. This can also be a way to find a strategic alternative to a high value addition of temple stay and dissemination of temple culture. For the research methodology, literature was reviewed over temple stay and Bulgeonsamul. For motive design and development of cultural product design, both Adobe Illustrator CS3 and Adobe Photoshop CS3 were used as computer design program. The template image of cloud-shaped gong for basic motive design was selected from those available at the domestic temples for accurate depiction of its head and body. Finally, samples were adopted from those temples of Gounsa, Songgwangsa, Guinsa, Hwaeomsa, and Naesosa. For each motive, different colors were applied and ten basic motives were practiced in total. By repeating the process for these motives, three types of textile design were prepared. T-shirt designs used a round neckline as basic form, and it was designed for sleeved and sleeveless styles. Apron designs stressed V-neckline and two types were processed: one for the back seam line and the other for side seam line. Pendants were designed with modern and luxurious image so that so that it could be used in various types of accessories. Designs for the bedding applied pattern design of the motives and this was done in a way that gave the images a sense of stability and splendor.

Purpose: Preventing frequent change and discontinuation of the nurses' carrier is one of major issues for human resource management in a health organization (HO). This study was conducted to get evidences for improvement nursing manpower management and career development of the clinical nurses through investigating affecting factors to their career withdrawal intention (CWI). Methods: A self-report questionnaire survey was conducted on the subjects of the 590 clinical nurses with more than one year tenure from the eight hospitals in Busan city during December, 2013. Data analysis was performed using SPSS program (ver 20.0) and AMOS program (ver 20.0) for structural modeling. Results: Career satisfaction (CS) showed positive(+) effects, and increased with higher job adequacy (${\beta}=.139$, t=2.676, p=.007), job autonomy (${\beta}=.260$, t=4.815, p<.001), and career planning (${\beta}=.301$, t=5.797, p<.001). Career commitment (CC) showed positive(+) effects, and increased with higher job adequacy (${\beta}=.107$, t=2.280, p=.023), job autonomy (${\beta}=.257$, t=5.035, p<.001), career planning (${\beta}=.232$, t=4.717, p<.001), and career satisfaction (CS)(${\beta}=.123$, t=2.293, p=.022). CWI showed negative(-) effects and increased with lower CC (${\beta}=-.906$, t=-15.72, p<.001). Conclusion: Results indicate that CC and CS have important mediating roles between job adequacy, job autonomy, career planning and CWI. As CC directly influenced CWI, there is a need to strengthen CC to prevent frequent changes and discontinuation of nurses' careers and to contribute to productivity HO's.

This study was conducted to establish methods for preserving chicken primordial germ cells (PGCs) for long-term storage in liquid nitrogen and for developmental engineering or preservation of species. The purpose of this study is to clarify the effects of fetal bovine serum (FBS) or chicken serum (CS) treatment on the viability of cryopreserved PGCs from Korean Native Chicken (Ogye). PGCs separated from a germinal gonad of an early embryo at day 5.5-6 (stage 28) were suspended in a freezing medium containing freezing and protective agents (dimethyl sulfoxide (DMSO), ethylene glycol (EG) and glycerol). The values from 0, 5, 10, and 15 % DMSO plus FBS treatment were 21.6, 30.36, 36.42, 50.39, and 48.36 %, respectively. The viability of PGCs after freeze-thawing was significantly higher for 10% EG plus FBS treatment than for 10% EG + FCS treatment (p<0.05) (64.36% vs. 50.66%). This study establishes a method for preserving chicken PGC that enables systematic storage and labeling of cryopreserved PGC in liquid nitrogen at a germplasm repository and an ease of entry into a database. In the future, the importance for this new technology is that poultry lines can be conserved while work is being conducted to improve the production of germline chimeras.

The effects of gamma irradiation at medium dose levels on commercial starches (corn starch/CS, sweet potato starch/SS, and potato starch/PS) were investigated in terms of its color and lipid oxidation. The CS, SS, and PS samples were irradiated at 0, 1.5, 3, 4.5 and 6 kGy by a Co-60 gamma irradiator and used for measuring Hunter's colors and TBA value. Irradiation doses applied did not cause apparent changes in Hunter color parameters between the control and irradiated groups. But, the decrease in lightness (L value) for CS and the increase in both redness (a value) for SS and yellowness (b value) for PS were observed, respectively, thereby resulting in slight increase in overall color difference (${\Delta}E$) upon irradiation. Browning intensity observed with the naked eye for gelatinized starches by irradiation doses was also gradually increased along with irradiation dose, which was more remarkable in SS. The thiobarbituric acid (TBA) values of samples showed a dose-dependant increase with ${\geq}0.9964$ of $R^2$ (p<0.05).

On farm evaluation for the control of airborne diseases like FMD and flu virus has been done in past but control of disease in process of transportation of livestock and manures is still needed. The objective of this study was to predict a common pattern of livestock vehicles movement. The analysis were done on GPS data, collected from drivers of livestock vehicles in Jeju Island, South Korea in year 2012 and 2013. The GPS data include the coordinates of moving vehicles according to time and dates, livestock farms and manure keeping sites. 2012 year data was added to ArcGIS and different tools were used for predicting common vehicle moving pattern. The common pattern of year 2012 were determined and considered as predicted common pattern for year 2013. To compare with actual pattern of year 2013 the same analysis was done to find the difference in 2012 and 2013 pattern. When the manure keeping sites and livestock farms were same in both years, as a result common pattern of 2012 and 2013 were similar but difference were found in patterns when the manure keeping sites and livestock farms were changed. In future for more accurate results and to predict the accurate pattern of vehicles movement, more dependent and independent variables will be required to make a suitable model for prediction.

Atopic dermatitis (AD) is a common chronic inflammatory disease associated with a cutaneous hypersensitivity reaction to an allergen. Although the incidence of AD is increasing these days, therapeutics has yet to be developed for its treatment. The aim of this study was conducted in order to compare and investigate the characteristic between the Castanea crenata inner shell extract (CS) and the Castanea crenata inner shell extract fermented by Lactobacillus bifermentans (FCS) for an anti-atopic medication. The total polyphenol and flavonoid contents were similar to CS and FCS. In the DPPH and superoxide anion radical scavenging, the CS and FCS had the potential for antioxidant activities. Both of them did not exhibit cytotoxicity to HS68 cells. The evaluation of the anti-inflammatory activity in Raw264.7 cells demonstrated that the FCS has inhibited the LPS-induced production of nitric oxide as compared to the CS. The anti-atopic dermatitis test was done through the induction of DNCB in AD hairless mice. The FCS has inhibited the development of the atopic dermatitis-like skin lesion by transdermal water loss, melanin and erythema of the skin as compared to the CS. Moreover, the pro-inflammatory cytokine IL-$1{\beta}$ and TNF-${\alpha}$ production in hairless mice were inhibited by the FCS treatment. It indicates that the fermentation of the Castanea crenata inner shell has the potential for the treatment of atopic dermatitis.

The purpose of this study is to establish a new method to develop the textile pattern design using Saengbul flower in Seo-cheon flower garden of Jeju Myth, in other words, to create mythic textile patterns by borrowing effectively from the mythic image of Saengbul flower. Seo-cheon flower garden is an incantation space and Saengbul flower means pregnance. Therefore, we drew Camellia flower motifs from a mythic image based on archetypal symbols about the Saengbul flower, and created mythic patterns. In order to achieve this textile pattern design, Adobe CS5(Photoshop, Illustrator) and Texpro were used to design the motifs of Saengbul flower, and then they were arranged in a square pattern and diamond pattern of Richard M. Proctor' set layout. And to conclude, development of the creative textile pattern design using the mythic contents of the Jeju Myth contribute to invigoration the fashion industry and regional culture contents projects in Jeju, and also become the basis of creating added valued to it.

Avian pathogenic Escherichia coli (APEC) is a causative agent for a number of extra intestinal diseases and account for significant losses to the poultry industry. Since protective immunity against APEC is largely directed to virulence antigens, we have individually expressed four different viulence antigens, papA, papG, IutA, and CS31A, using an attenuated Salmonella Typhimurium and a plasmid pBB244. Following oral immunization of mice with combination of two or four of these strains, serum IgG and mucosal IgA responses were elicited against each antigen represented in the mixture. The antigen-specific mucosal IgA responses were significantly higher in the group of mice immunized with the heat-labile Escherichia coli enterotoxin B subunit (LTB) strain than those in the group of mice immunized without the LTB strain. While, there was no significant difference between these two groups in antigen-specific serum IgG responses. The results showed that LTB could act as mucosal immune adjuvant. To assess the nature of immunity, the distribution of antigen-specific IgG isotypes was analyzed. All groups promoted Th1-type immunity as determined by the IgG2a/IgG1 ratio. Thus, our findings provided evidence that immunization with a combination of several vaccine strains is one of the strategies of developing effective vaccines against APEC.
