Raised or plain block is widely used for the pedestrian's safe passage. The insincere construction, insufficient maintenance and obstacle overlaid on the pavement cause pedestrian's accidents. This paper proposes a method to detect brick path by analyzing the shape pattern and texture feature of brick located in visible distance for a safe passage. A brick appears to a regular type because of its specific shape which repeats with its sized gap and its type varies according to the surrounding environment or use. This paper shows a method which extracts the shape pattern by analyzing single surface polygon and its frequency appearing in road area. The shape pattern is used to detect similar shape regions. Some regions are not detected because extraneous substances or chopped bricks distort the original shape. This problem can be solved by analyzing the texture feature vector. The analyzed vector of the previously detected regions yields the Gaussian distribution. This value in each undetected region is computed and checked whether it's satisfied with Gaussian distribution or not. The satisfied region is detected as the brick path. The experiment was performed with the various type's bricks to recognize so that the results showed as accurate as 95.9% in average.

To investigate genetic diversity and PCR detection of Rhizina undulata, PCR detection and sequence analysis of rDNA ITS region of R. undulata in soil were analyzed and developed. The length of partial 18S rDNA from four R. undulata isolates were 1,375 nt. The sequence similarity of R. undulata isolates was 100%. The rDNA ITS regions of R. undulata isolates were 585 nt long. Nucleotide sequencing of the ITS regions showed that PDK-1, PTT-1 and PDJ-9 isolates had 100% sequence identity. But, PDS-5 isolate differed from the three isolates by two nucleotide substitution. R. undulata-specific primers designed by the sequence of ITS region were used in PCR detection of R. undulata. PCR products about 525 bp size, which is specific to R. undulata, were amplified from total DNAs of R. undulata isolates. To assay the sensitivity of PCR detection by R. undulata ITS-specific primer, purely cultured mycelial suspension of R. undulata was serially diluted and mixed with 100g of sterile sandy loam soil, respectively. And then, PCR products of total DNAs extracted from each mycelium-soil mixtures were analysed. The PCR protocol could detected up to 1ng mycelium of R. undulata within 100g of soil.

This paper proposes a motion segmentation algorithm for layer decomposition of image sequences. The proposed algorithm segments an image into initial regions by using its color and texture and computes a motion model of each initial region. Each pixel assigns one of the motion represented by the models or a motion except them, which segments the image into the motion regions. The proposed algorithm is app]ied image sequences and the segmented motion is shown.

Stereo image analysis has been an important tool for reconstructing 3D terrain. By In its nature, occlusion is one of difficulties we cannot avoid in stereo matching. This paper presents a study on occlusion detection by employing LRC(Left-Right Check) and OCC(Occlusion Constraint). Experimental results show that these method can effectively detect occluded regions and those regions are usually occurred around object contours and scene discontinuity.

The electrical characteristics of NMOSFETs with asymmetrical source/drain regions have been expermentally investigated using test devices fabricated by $0.35\mu\textrm{m}$ CMOS technology. The performance degradation for asymmetric transistor and its causes are analyzed. The parasitic resistances, such as series resistance of active regions and silicide junction contact resistance, are distributed in parallel along the channel. Depending on source/drain geometry, the array of those resistances is changed, that results the various electrical properties.

The molecular clouds associated with bright optical HII regions Sh 254-258 are studied with the TRAO CO observations and with the WISE near-infrared emission. Based on the morphology of the clouds and the basic physical parameters derived with the LTE analysis, Pieces of evidences for physical interactions with its surroundings are investigated.

Penicillium georgiense was isolated from sandy beach soil from Batu Ferringhi beach, Penang Island, Malaysia. The identification was based on morphological characteristics and phylogenetic analysis of internal transcribed spacer regions and ${\beta}$-tubulin sequences. To the best of our knowledge, this is the first report of P. georgiense in Malaysia.

Three isolates of Penicillium pimiteouiense were recovered from sandy beach soil samples in Penang Island, Peninsular Malaysia. All the isolates were identified based on morphological characteristics and phylogenetic analysis of internal transcribed spacer regions and ${\beta}$-tubulin gene. This is a first record of P. pimiteouiense in Malaysia.
