SOA has become the focus of attention as it is perceived as a concept toward integrative service which helps companies respond quickly to the changes in market needs. This study is aimed to find out success factors for building SOA. We carried out two case studies on companies that adopted SOA successfully in Korea and conducted a survey to collect opinions from experts and experienced managers whose job is related to SOA. The critical successful factors found in this study include: 1) establishment of the SOA taskforce based on CIO's strong support, 2) formation of the corporate-wide consensus and the adoption of standards, 3) active user participation in defining services and obliterating duplication, 4) accomplishment of flexibility in services and business agility based on integrated infrastructure, and 5) securing project budget and consistent support by way of using measurement index for SOA investment effects.

Taoyuan pig is a native Taiwan breed. According to the historical record, the breed was first introduced to Taiwan from Guangdong province, Southern China, around 1877. The breed played an important role in Taiwan's early swine industry. It was classified as an indigenous breed in 1986. After 1987, a conserved population of Taoyuan pig was collected and reared in isolation. In this study, mitochondrial DNA sequences and 18 microsatellite markers were used to investigate maternal lineage and genetic diversity within the Taoyuan pig population. Population differentiation among Taoyuan, Asian type, and European type pig breeds was also evaluated using differentiation indices. Only one D-loop haplotype of the Taoyuan pig was found. It clustered with Lower Changjiang River Basin and Central China Type pig breeds. Based on the polymorphism of microsatellite markers, a positive fixation index value ($F_{IS}$) indicates that the conserved Taoyuan population suffers from inbreeding. In addition, high $F_{ST}$ values (>0.2105) were obtained, revealing high differentiation among these breeds. Non-metric multi-dimensional scaling showed a clear geometric structure among 7 breeds. Together these results indicate that maternally Taoyuan pig originated in the Lower Changjiang River Basin and Central China; however, since being introduced to Taiwan differentiation has occurred. In addition, Taoyuan pig has lost genetic diversity in both its mitochondrial and nuclear genomes.

According to the Global Retail Development Index (GRDI) published by A.T. Kearney (2012), India is the $5^{th}$ most attractive retail destination in the world. The retail industry in India has been largely fragmented with small businesses dominating the retail landscape, with very few large players having multiple retail outlets. However, in the last few years, the industry has witnessed a significant growth in the number of large retailers having a chain of outlets across the country. This growth in the organised retail sector has driven primarily by large Indian retail organisations and conglomerates. With the government reducing the restrictions on foreign participation in Indian retail business by increasing the FDI cap on both single and multi-brand retail outlets, the industry is likely to see an explosive growth in the organised retail sector which accounts for only 8 percent of the total industry. With more foreign retailers poised to enter into the country, one of the key issues that the industry may face is finding the right quality of manpower. Literature suggests that in an industry which is characterised by players offering similar kinds of product assortments at similar price levels, success would be governed by the quality of service, which entails employees having the right skills and attitudes for offering quality service. Therefore, the two key issues that may be of importance for retailers are levels of skills and the motivation of the employees. However, according to the National Skill Development Corporation (NSDC, 2009), a significant skill gap exists in the industry, which may widen further in the years ahead, leading to greater challenges for organisations. This paper highlights some of the challenges and issues which characterise the industry in India, and suggests how companies could look at these challenges and seek ways to overcome these challenges.

Objectives: The aim of this study is to compare the shear bond strengths of ceramic brackets bonded to zirconia surfaces using different zirconia primers and universal adhesive. Materials and Methods: Fifty zirconia blocks ($15{\times}15{\times}10mm$, Zpex, Tosoh Corporation) were polished with 1,000 grit sand paper and air-abraded with $50{\mu}m$ $Al_2O_3$ for 10 seconds (40 psi). They were divided into 5 groups: control (CO), Metal/Zirconia primer (MZ, Ivoclar Vivadent), Z-PRIME Plus (ZP, Bisco), Zirconia Liner (ZL, Sun Medical), and Scotchbond Universal adhesive (SU, 3M ESPE). Transbond XT Primer (used for CO, MZ, ZP, and ZL) and Transbond XT Paste was used for bracket bonding (Gemini clear ceramic brackets, 3M Unitek). After 24 hours at $37^{\circ}C$ storage, specimens underwent 2,000 thermocycles, and then, shear bond strengths were measured (1 mm/min). An adhesive remnant index (ARI) score was calculated. The data were analyzed using one-way analysis of variance and the Bonferroni test (p = 0.05). Results: Surface treatment with primers resulted in increased shear bond strength. The SU group showed the highest shear bond strength followed by the ZP, ZL, MZ, and CO groups, in that order. The median ARI scores were as follows: CO = 0, MZ = 0, ZP = 0, ZL = 0, and SU = 3 (p < 0.05). Conclusions: Within this experiment, zirconia primer can increase the shear bond strength of bracket bonding. The highest shear bond strength is observed in SU group, even when no primer is used.

We are facing the era of multi-identities in which locals got emphasized, whereas nations'boundary are breaking off under the expansion of de-bounadarisim. In this trend, local autonomous governments are striving to have foreign competitiveness through reforming their administration, such as adopting management styles of companies. If the purpose of administration is set for developing 'the quality of residents' life', introducing 'design' into administration would be one of the best ways. By adopting this design concept, residents 'happiness index' will be increased so that residents' capability will be consolidated to contribute to the development of the local economy. The purpose of this study is to examine various cases of introducing 'design concept' into administration in local autonomous entities. All the methods of introducing design concept are analysed and the implementation methods are proposed. If local autonomous entities operate the design based administration proposed by this study, and if this is relevant to locals, it will create its unique local image and contribute to increasing 'the quality of residenfs life' as well.

The Urban Environmental Quality (UEQ) indicates a complex and various parameters resulting from both human and natural factors in an urban area. Vegetation, climate, air quality, and the urban infrastructure may interact to produce effects in an urban area. There are relationships among air pollution, vegetation, and degrading environmental the urban heat island (UHI) effect. This study investigates the application of multi-spectral remote sensing data from the Landsat ETM and TM sensors for the mapping of air quality and UHI intensity in Seoul from 2000 to 2006 in fine resolution (30m) using the emissivity-fusion method. The Haze Optimized Transform (HOT) correction approach has been adopted for atmospheric correction on all bands except thermal band. The general UHI values (${\Delta}(T_{urban}-T_{rural})$) are 8.45 (2000), 9.14 (2001), 8.61 (2002), and $8.41^{\circ}C$ (2006), respectively. Although the UHI values are similar during these years, the spatial coverage of "hot" surface temperature (>$24^{\circ}C$) significantly increased from 2000 to 2006 due to the rapid urban development. Furthermore, high correlations between vegetation index and land surface temperature were achieved with a correlation coefficients of 0.85 (2000), 0.81 (2001), 0.84(2002), and 0.89 (2006), respectively. Air quality is shown to be an important factor in the spatial variation of UEQ. Based on the quantifiable fine resolution satellite image parameters, UEQ can promote the understanding of the complex and dynamic factors controlling urban environment.

This study was begun to classify the paddy fields by the rice varieties and to monitor the temporal change in rice growth using SAR backscatter coefficients $({\sigma}^{circ})$. For nine fine-beam mode images of Radarsat-1 SAR, a growing period time-series of backscatter coefficients was set up from April to October in 2005, and was compared with the field-measured rice growth parameters such as LAI (leaf area index), plant height, fresh and dry biomass, and water content in grain and plant for 45 parcels in Dangjin-gun, Chungcheongnam Province, South Korea. The average backscatter coefficients for early-maturing rice varieties (13 parcels) were ranged from -18.17dB to -6.06dB and were lower than for medium-late maturing rice varieties during most of the growing season. At around the heading stage (July 30) for early-maturing rice, both rice crops showed the highest backscatter coefficient values and the difference was the greatest before harvesting early-maturing rice. The temporal difference in backscatter coefficients between rice varieties was expected to play a key role to identify early-maturing rice fields. On the other hand, comparison with field-measured rice growth parameters showed that the backscatter coefficients decreased or stayed on the plateau after heading stage even though the growth of rice canopy advanced.

Traditional herbal medicine is widely used among the Korean people, and other eastern Asian countries employ similar therapies as well. In recent years, due to increasing interest in herbal medicines, many researches have been made on the toxicity and side effects of herbal medications. Through private and public media, there have been many opinions suggesting taking herbal medicines is very harmful, especially on the liver and kidney functions. This assertion has been mainly presented by the doctors that practice western medicine, But this assertion is never based on adequate knowledge of herbal medicine. This study aims to provide the evidences that taking herbal medicines is safe on the renal functions. Four frequently used herbal medications(Sipjeondaebotang, Bojungigitang, Ojeoksan, and Yukmijihwangtang) were used to test the toxicity of herbal medicine oh the lab animal model(SD-Rat). There is no significant difference in body weight and kidney weight after herbal medication for 1 month. In all experimental groups, no abnormal findings were observed in histological study, and lab renal function index(BUN, creatinine, uric acid). These results say that four herbal multi-used-medicines, when medicated, is safe from the renal toxicity in lab animal model.

Worldview-3 satellite sensor provides panchromatic image with high-spatial resolution and 8-band multispectral images. Therefore, an image-sharpening technique, which sharpens the spatial resolution of multispectral images by using high-spatial resolution panchromatic images, is essential for various applications of Worldview-3 images based on image interpretation and processing. The existing pansharpening algorithms tend to tradeoff between spectral distortion and spatial enhancement. In this study, we applied six pansharpening algorithms to Worldview-3 satellite imagery and assessed the quality of pansharpened images qualitatively and quantitatively. We also analyzed the effects of time lag for each multispectral band during the pansharpening process. Quantitative assessment of pansharpened images was performed by comparing ERGAS (Erreur Relative Globale Adimensionnelle de Synthèse), SAM (Spectral Angle Mapper), Q-index and sCC (spatial Correlation Coefficient) based on real data set. In experiment, quantitative results obtained by MRA (Multi-Resolution Analysis)-based algorithm were better than those by the CS (Component Substitution)-based algorithm. Nevertheless, qualitative quality of spectral information was similar to each other. In addition, images obtained by the CS-based algorithm and by division of two multispectral sensors were shaper in terms of spatial quality than those obtained by the other pansharpening algorithm. Therefore, there is a need to determine a pansharpening method for Worldview-3 images for application to remote sensing data, such as spectral and spatial information-based applications.
