This study was carried out to show at the fractal analysis complements the practical disadvantage of gray level histogram which is designed to measure the quantitative classification of echo patterns in ultrasonographic image of parenchymal organs such as spleen and kidney and it is a practical method of measurement for quantitative classification. By using ultrasonographs, kidney and spleen of 21 healthy Beagles were fixed under different gain settings to be scanned for echo patterns and results were analyzed with body gray level histogram and fractal analysis. Then it was compared based on the statistical data obtained. Although there was a proportionate increase in histogram along with gain settings, there were consistencies in the fractal dimension. In terms of quantitative analysis in ultrasonographic images, fractal analysis is concluded to complement the practical disadvantage of gray level histogram.

In this paper, a new program recommendation system is proposed to recommend user preferred VOD program in IPTV environment. A proposed system is implemented with hybrid filtering method that can cooperatively complements the shortcomings of the content-based filtering and collaborative filtering. For a user program preference, a single-scaled measure is designed so that the recommendation performance between content-based filtering and collaborative filtering is easily compared and reflected to final hybrid filtering procedure. In order to provide more accurate program recommendation, we use not only the user watching history, but also the user program preference and sub-genre program preference updated every week as a user preference profile. System performance is evaluated with modified IPTV data from real 24-weeks cable TV watching data provided by Nilson Research Corp. and it shows quite comparative quality of recommendation.

Self-healing is one of the techniques that assure dependability of mission-critical system. Self-healing consists of fault detection and fault recovery and fault detection is important first step that enables fault recovery but it causes overhead. We can detect fault based on model, the detection tasks that notify system's behavior and compare normal behavior model and system's behavior are heavy jobs. In this paper, we propose architecture-based multi-level self-adaptive monitoring method that complements model-based fault detection. The priority of fault detection per component is different in the software architecture. Because the seriousness and the frequency of fault per component are different. If the monitor is adapted to intensive to the component that has high priority of monitoring and loose to the component that has low priority of monitoring, the overhead can be decreased and the efficiency can be maintained. Because the environmental changes of software and the architectural changes bring the changes at the priority of fault detection, the monitor learns the changes of fault frequency and that is adapted to intensive to the component that has high priority of fault detection.

Gwaneumhyeonsanggi is a writing of praise of the incarnated White-robed Gwanseumbosal by Choi Hang which King Sejo witnessed at the top of Damhwajeon during his visit to Sangwonsa Temple. In Gwaneumhyeonsanggi, White-robed Gwaneumhwahyeondo drawn by a painter is attached, which demonstrate the feature of Sangwonsa temple in the early Joseon period. This study aimed to examine the landscape features of Sangwonsa in the early Joseon period by records and picture in Gwaneumhyeonsanggi. As a result, it was determined that the building display, spatial structure, building type and landscape arrangement seemed to be unique compared with other temples. In particular, the treatment of scenic stone(景石) is important in terms of landscape because it complements existing ideas and concepts that the temple landscape was mainly made of water as the main resources. Also the trees around the temple shown in the picture in can be compared with the current state of the data is valuable.

This paper presents the technique separating objects on the single frame image from the background using region segmentation technique based on active contour. Active contour is to extract contours of objects from the image, which is set to have multi-search starting point to extract each objects contours for multi-object segmentation. Initial rough object segments are generated from binary-coded image using object specific contour information, and then the hole filling is performed to compensate internal segmentation caused by the change of inner object hole area and pixels. This procedure complements the problems caused by the noise from the region segmentation and the errors of segmentation near by the contour. The proposed method and conventional method is compared to verify the superiority of the proposed method.

Purpose - The objectives of this study are as follows. First, it aims to suggest an analysis model that has integrated the relationship between the two factors and export performance and conduct an empirical analysis of the factors. Second, the study seeks to analyze the mediating effect by setting direct channel governance as a specific activity to connect market orientation, a cultural asset, to export performance. Third, through these analyses, the study intends to apply the relationship between market orientation and direct channel governance that the existing studies have failed to observe comprehensively on SMEs in Korea. Based on these analyses, the study expects to expand the discussion of previous researches by analyzing the mediating effect of direct channel governance. Research design, data, and methodology - This study developed a model that has integrated market orientation, direct channel governance, and export performance. It established 7 hypotheses including the mediating effect of direct channel governance. Market orientation was consisted of customer orientation and competitor orientation, and 4 latent variables were measured by 18 questions. LISREL, an analysis tool of structural equation model, was used for hypothesis test and there were 183 sample for analysis. Results - The analysis results showed that customer orientation has a positive influence on direct channel governance, but competitor orientation did not have a statistically significant effect. On the contrary, export performance showed an opposite result. That is, customer orientation did not have any influence but competitor orientation had a significant influence on export performance. It was also confirmed that there was a significant influence in the relationship between channel governance and export performance. According to the analysis of mediating effect, direct channel governance had a full mediating effect between customer orientation and export performance. Conclusions - The study results demonstrated that it is important to build a direct channel governance on the export SMEs in Korea, especially since the direct channel governance complements the influence of customer orientation that does not directly influence export performance among market orientation activities. This implies that Korean export SMEs must strive to build an effective direct channel governance.

This paper investigates the manner in which house prices affect macroeconomic variables through a house price channel by applying the method of Iacoviello (2005) to Korean data, and establishing a DSGE model with complementarity. This paper found that higher LTV ratio coupled with stronger complementarity results in the co-movement in both consumption and housing. For instance, the results show that when the LTV ratio and complementarity stands respectively at 50% and 0.42, an 1% rise in house prices increases consumption by 0.057%, and when the complementarity parameter increases to 0.52 with LTV remains unchanged at 50%, consumption rises by 0.047% per 1% increase in house prices. An increase in house prices leads credit constraints for borrowers to become more loose as value of a house rises as a collateral. The increase in household credit enables more consumer spending, eventually leading to increased consumption. A key link in which house prices are connected to macroeconomic variables is change in consumption. To put it simply, a rise in house prices leads to an increase in consumption, which consequently impacts the overall macro-economy. At this point, complementarity is found, in that the elasticity of intra-temporal substitution between housing and consumption is estimated at 0.42, which plays an important role in the house price channel by amplifying the effects of house prices on consumption.
