For a System-on-a-Chip(SoC) comprised of multiple IP cores, various design techniques have been proposed to provide diverse test link configurations. In this paper, we introduce a new flag based Wrapped Core Linking Module (WCLM) that enables systematic integration of IEEE 1149.1 TAP'd cores and P1500 wrapped cores with requiring least amount of area overhead compared with other state-of-art techniques. The design preserves compatibility with standards and scalability for hierarchical access.

Moving object boundary is very important for moving object segmentation. But the moving object boundary shows broken boundary We invent a novel space-oriented boundary linking algorithm to link the broken boundary The boundary linking algorithm forms a quadrant around the terminating pixel in the broken boundary and searches forward other terminating pixel to link within a radius. The boundary linking algorithm guarantees shortest distance linking. We also register the background from image sequence. We construct two object masks, one from the result of boundary linking and the other from the registered background, and use these two complementary object masks together for moving object segmentation. We also suppress the moving cast shadow using Roberts gradient operator. The major advantages of the proposed algorithms are more accurate moving object segmentation and the segmentation of the object which has holes in its region using these two object masks. We experiment the algorithms using the standard MPEG-4 test sequences and real video sequence. The proposed algorithms are very efficient and can process QCIF image more than 48 fps and CIF image more than 19 fps using a 2.0GHz Pentium-4 computer.

We use a volume-limited sample of quasars in the Sloan Digital Sky Survey (SDSS) DR7 quasar catalog to identify quasar groups and address their statistical significance. This quasar sample has a uniform selection function on the sky and nearly a maximum possible contiguous volume that can be drawn from the DR7 catalog. Quasar groups are identified by using the Friend-of-Friend algorithm with a set of fixed comoving linking lengths. We find that the richness distribution of the richest 100 quasar groups or the size distribution of the largest 100 groups are statistically equivalent with those of randomly-distributed points with the same number density and sky coverage when groups are identified with the linking length of $70h^{-1}Mpc$. It is shown that the large-scale structures like the huge Large Quasar Group (U1.27) reported by Clowes et al. (2013) can be found with high probability even if quasars have no physical clustering, and does not challenge the initially homogeneous cosmological models. Our results are statistically more reliable than those of Nadathur (2013), where the test was made only for the largest quasar group. It is shown that the linking length should be smaller than $50h^{-1}Mpc$ in order for the quasar groups identified in the DR7 catalog not to be dominated by associations of quasars grouped by chance. We present 20 richest quasar groups identified with the linking length of $70h^{-1}Mpc$ for further analyses.

The Purpose of this study is to suggest the necessity of linking and coordinating Cultural Tourism Festivals among local governments and to propose a plan for maximizing the effects of these festivals. The 'World Ceramic Exposition 2001 Korea' which took place from August 10th to October 28th was selected as a case study for the linkage plan of Cultural Tourism Festivals among local governments. Data were collected from a random sampling of visitors to 'World Ceramic Exposition 2001 Korea' from 24 to 28 October, 2001. 369 samples from a total 375 respondents were used for the final analysis. The contents of the questionnaire consisted of the cognition and satisfaction about the effects of the festival linkage among local governments and the preference of festival linkage types. The results of the analysis showed that not only festival staff but also visitors recognized the necessity of linking festivals among regions. Both visitors and festival staff had a positive attitude about the effects of the linked festival. In addition, they highly rated the 'World Ceramic Exposition 2001 Korea' as a successful festival. Visitors were satisfied with the festival. Furthermore, the number of visitors was more than staff expected. The organizing committee and staff considered the 'World Ceramic Exposition 2001 Korea' as a successful festival. The successful evaluation of the 'World Ceramic Exposition 2001 Korea' was related to the successful linkage of the festival. This study originated in the increased necessity of linking cultural Tourism Festivals among local governments. Since it is a transcendental study, it is not only significant but also limited. However, in the near future, more varied case studies about the linkages of Festivals will be conducted and these will generalize the results of this study and test the effectiveness of the linkage plans through positive analysis. For the effective linking of festivals among regions, it is necessary to study the definition of factors that affect visitors satisfaction, and determine which methods will improve visitors satisfaction.

This study analyzed the effect of semi-rigid rafter-purlin cross-linking connection and driven steel pipe base on the static behavior of plastic greenhouse (PG). To promote the time and cost efficiency of the assembly process, each cross-linking connections of space arch type grid that consists of rafter and purlin is linked with steel-wire buckles, and each end of the rafters was driven directly to the ground to support the PG structure. However, in the design process, cross-linking connections and bases are idealized by being categorized as fully rigid or frictionless pinned, which does not appropriately reflect actual conditions. This study takes a full-scale loading test of PG and analyzes the effect of member cross-linking connections and driven steel pipe base on the behavior of a structure. The analysis provided a basis for determining the rigidity factor of member cross-linking nodes needed for finite element analysis, and the reliability of the result regarding the static behavior of PG.

Capture-and-replay technique is a common automatic method for GUI testing. Testing applications on Android platform cannot use directly capture-and-replay technique due to the testing framework which is already set up and technical supported by Google and lack of automatic linking GUI elements to actions handling widget events. Without capture-and-replay testing tools testers must design and implement testing scenarios according to the specification, and make linking every GUI elements to event handling parts all by hand. This paper proposes a more improved and optimized approach than common capture-and-replay technique for automatic testing Android GUI widgets. XML is applied to extract GUI elements from applications based on tracing the actions to handle widget events. After tracing click events using monitoring in capture phase test cases will be created by communicating status of activated widget in replay phase with API events.

PURPOSE: This study was conducted to suggest a way to easily understand and utilize the International Classification of Functioning, Disability and Health (ICF) or Korean Standard Classification of Functioning, Disability and Health (KCF), a common and standard language related to health information. METHODS: The tools used by physical therapists to evaluate the functioning of neurological patients were collected from 10 domestic hospitals. By applying the ICF linking rule, two experts compared, analyzed, and linked the concepts in the items of the collected tools and the ICF/KCF codes. The frequency of use of the selected tool, the matching rate of the liking results of two experts, and the number of the codes linked were treated as descriptive statistics and the code set was presented as a list. RESULTS: The berg balance scale, trunk impairment scale, timed up and go test, functional ambulation category, 6 Minute walk test, manual muscle test, and range of motion measurements were the most commonly used tools for evaluating the functioning. The total number of items of the seven tools was 33, and the codes linked to the ICF/KCF were 69. Twenty-two codes were mapped, excluding duplicate codes. Ten codes in the body function, 11 codes in the activity, and one code in the environmental factor were included. CONCLUSION: The information on the development process of the code set will increase the understanding of ICF/KCF and the developed code set can conveniently be used for collecting patients' functioning information.
