Studies were carried out to describe the structure and distribution of various sensilla on the antenna and mouthparts of the Oriental tobacco bud worm (H. assulta) larvae by light and scanning electron microscopy. The larval antenna has 3 segments. The second segment has 2 hairs and 3 pegs, while the third segment shows 3 regular pegs and a segmented peg (styloconicum type). Each mandible bears 2 aporous hairs on the lateral surface. The labrum bears 12 aporous hairs on its external surface. and 6 aporous hairs, 4 coeloconica-like sensilla and 2 campaniformia-like sensilla on its epipharynx. The stipes has 3 hairs, and the galea has 3 pegs. 2 papillae and 2 domes. The maxillary palpus has only a digitiform sensillum on its 1st segment but 11 sensilla of 4 different types on its 2nd segment. Maxillary sensilla represent almost 70% of total number of larval sensilla on the mouthparts. Labial pal pus has a single segment bearing a large segmented uniporous peg and a small peg. Finally their possible fun¬ctions were suggested.

This study aims to identify the cause for low appearance of flowers in 'Heukgoosul' grapevines, and determine basic characteristics of the axillary buds and types of necrosis in order to find out their influence on necrosis. As for $1^{st}$ to $4^{th}$ node, the closer buds were located to cane, the smaller the size of buds became. However, there was no difference in the size of an axillary bud in the upper part of the shoot above the 4th node. The bud necrosis occurrence in the $1^{st}$ node was the highest with 32% while buds in $4^{th}$ to $10^{th}$ node were normal with 84~96%. The size of buds in July was the largest with 6.40 mm, while buds showed no difference from August to October. The bud necrosis and main bud necrosis occurred most frequently in October, however accessory bud necrosis took place from July demonstrating no difference since then. The analysis on the relationship between shoot vigor and necrosis of axillary buds showed that the shoot diameter and internodes' length have no co-relationship with axillary bud necrosis, but there were negative relationship between the size of buds and necrosis occurrence, which was the most related to accessory bud necrosis. Therefore, despite the low occurrence of bud necrosis and healthy buds in 'Heukgoosul' grapevines, there was little appearance of flowers in the grapevines, which was attributable to the necrosis in the first bud. In conclusion, the research suggests spur pruning with three nodes kept intact yield.

This study was conducted to examine characteristics of rhizome growth and flowering of white lotus (Nelumbo nucifera) plant in Muan Hoesan-lake for collecting the basic data on the cultivation and the flowering which is growing in Muan Hoesan-lake of Jeonnam province in Korea. We have planted from the seeds and the enlarged rhizomes of the white lotus which were planted in the plastic containers on April 20 and May 4, 2008, and cultivated under rain shelter condition. Rhizome growth pattern and the flowering characteristics of the white lotus were examined on September 4, 2008. Main rhizomes of the white lotus propagated by the seeds and the enlarged rhizomes were branched by 10% and 15%, respectively. Numbers of nodes in the bloomed and non-bloomed rhizomes of the white lotus were over 14 and below 11, respectively. Flower was not observed in the white lotus when propagated with seeds, however, flowers came out up to 80% by the enlarged rhizomes. First flowers were bloomed from the late July and to the early August, and the number of flowers were 4.0~4.4. The first flower stalks without branching of the main rhizome were emerged in 8.8th node, however, that with branching were 8.0th node. Time to flowering from the emergence of flower stalk on the above-ground parts were required 16 days. White flowers from the lotus were 15.3 cm in height and 28.2 cm in width, their longevity was 3.3 days and the averaged flower fresh weight was 29.2 g. The results conclude that optimum number of nodes on the main rhizomes for blooming the white lotus flowers should be over 8 nodes before the rhizome enlargement.

Filippinodillo flavimaculis and F. palawanensis from Philippines, are described as new species. For the presence of a ledge on pereonal epimeron 1, F. flavimaculis resembles both of the previously known species, F. maculatus Schmalfuss, 1987 and F. kimberleyensis Lewis, 1998, but differs from F. maculatus in the shape of frontal shield and from F. kimberleyensis in the shape of ventral surface of pereonal epimera 3-7 and pleonal epimeron 3. F. palawanensis is easily distinguished from all the others in the genus by the shape of the pereonal epimeron 1 not forming a ledge and with lateral margin grooved entirely.

Two new species of the genus Burmoniscus, B. siamenis and B. phanganensis, are described from Ko Samui and Ko Pha Ngan, Thailand. B. siamenis is similar to B. mauritiensis (Taiti and Ferrara, 1983) in color pattern and the shape of telson, but distinguished by the shape of pereonite 7 with obtuse postero-lateral angle and the peculiar shape of male pleopod 2 endopod with truncated apex. B. phanganensis is close to B. ocellatus Verhoeff, 1928) in the shape of pereonite 7 and telson, but easily distinguished by the peculiar shape of male pleopod 1 endopod with two rows of denticles on caudal surface.

Two flavonoids were isolated from the aerial parts of Salicornia herbacea L. by column chromatography. The structures of the flavonoid compound 1 and 2 were identified as quercetin $3-O-{\beta}-D-glucopyranoside$ and isorhamnetin $3-O-{\beta}-D-glucopyranoside$, respectively. The antioxidant activity of compound 1 was similar to those of quercetin and rutin, and the activity of compound 2, which contained methoxyl group at flavonoid B-ring, was lower than that of compound 1. The two compounds 1 and 2 were the first to be reported in this plant.

This paper studied scrambling occurrence in the line coder for UTF-8 hangul syllable code based on unicode. The paper suggested that scrambling is occurred when consecutive four "0" bit is entered into the line coder from the source codes. Currently, ITU-T is applying HDB-3 scrambling method in AMI line coder, According to the study result, scrambling is occurred about 39% in UTF-8 code on Unicoe Hangul syllable.

To enhance the proliferation efficiency of Menyanthes trifoliata L. endangered species in Korea, various rhizome cuttings were tested based on cutting length and node numbers. Growth length and increased volume of rhizomes were highest on long cuttings of 10-18cm length. But relative growth length of rhizomes were higher in short cuttings of 2-4cm and medium cutting of 4-10cm length than in long cuttings. Relative increased volume of rhizomes was highest in medium cuttings. The node numbers were not contributed to the efficiency of relative growth of rhizomes. This study suggests that medium length cutting is the best practice for the proliferation of M. trifoliata.

This study was conducted to determine the amount of flavonoids in Salicomia herbacea L. grown by a liquid chromatography / mass spectrometry (LC/MS). The flavonoids-contained quercetin (124.43 ppm), rutin (2.57 ppm), quercetin-3-${\beta}$-glucoside (3992.49 ppm), quercetin-3',4'-glucoside (0.08 ppm) and isorhamnetin (27.81 ppm) were detected in the powder sample. In particular, quercetin-3-${\beta}$-glucoside accounted for more than 99% in hay and 96% in powder. These results suggest that S. herbacea, which is one of halophyte plants, has high functional substances as an antioxidant source.

This paper proposes three methods for improving the accuracy of auto-music transcription considering with time-varying tempo from monophonic sound. The first one that uses TV(Total Variation) filter for smoothing the pitch data reduces the fragmentation in the pitch segmentation result. Also, the measure finding method that combines three different ways based on pitch and energy of sound data, respectively as well as based on rules produces more stable result. In addition the temporal result of note-length encoding is corrected in optimal way that the resulted encoding minimizes the sum of quantization error in a measure while the sum of note-lengths is equal to the number of beats. In the experiment with 16 children songs, we obtained the improved result in which measure finding was complete, the accuracy of encoding for note-length and pitch was about 91.3 and 86.7, respectively.
