  • Carbofuran was incubated for four weeks in five types of paddy soil samples at $25^{\circ}C$. The soil samples prepared in the study were as follows : control soil, sterilized soil, 10% cellulose added soil, 10% cellulose and 1% ferrous sulfate added soil, and 10% cellulose and 1% magnesium sulfate added soil. The degradation rate of carbofuran was significantly decreased(p<0.05) in sterilized soil.The degradation rate of carbofuran was significantly decreased by addition of cellulose(p<0.05) in femous sulfate added soil and magnesium sulfate added soil(p<0.01).

  • The contention overhead on the same channel in an NoC architecture can significantly increase a communication delay due to the simultaneous communication requests that occur. To reduce the overall overhead, we propose task-to-tile binding techniques for an NoC-based manycore platform, whereby it is assumed that the task mapping decision has already made. Since the NoC architecture may have multiple memory tiles as its size grows, memory clustering is used to balance the load of memory by making applications access different memory tiles. We assume that the information on the communication overhead of each application is known since it is specified in a dataflow task graph. Using this information, this paper proposes two heurisitics that perform binding of multiple tasks at once based on a proper memory clustering method. Experiments with an NoC simulator prove that the proposed heurisitic shows performance gains that are 25% greater than that of the previous binding heuristic.

  • This paper concerns automatic hardware synthesis from data flow graph (DFG) specification for fast HW/SW cosynthesis. A node in BFG represents a coarse grain block such as FIR and DCT and a port in a block may consume multiple data samples per invocation, which distinguishes our approach from behavioral synthesis and complicates the problem. In the presented design methodology, a dataflow graph with specified algorithm can be mapped to various hardware structures according to the resource allocation and schedule information. This simplifies the management of the area/performance tradeoff in hardware design and widens the design space of hardware implementation of a dataflow graph compared with the previous approaches. Through experiments with some examples, the usefulness of the proposed technique is demonstrated.

  • A new light pink spray-mum, 'Noble ND' was bred by crossing 'Mona Lisa', a white anemone type flower, and 'Dark Weldon', a pink anemone type flower in October, 2004. The growth and flowering characteristics were investigated in forcing, natural, and retarding cultures from 2006 to 2007. The 'Noble ND' was a medium-flowering fall-mum with light pink anemone type flower and had 9.2 flowers per stem, with 4.8 cm flower diameter in natural culture. The number of days to flowering and flowers per plant was 57 and 7.4, respectively, in forcing culture of 'Noble ND', whereas the number of days to flowering was 48 in retarding culture.

  • Osteomyelitis is considered an inflammatory condition of bone that usually begins as an infection of the medullary cavity and quickly extends to periosteum of the area. Early acute osteomyelitis of the mandible is usually characterized by deep, intense pain, high intermittent fever, paresthesia or anesthesia of the lower lip and a clearly identifiable cause. If the disease is not controlled or inadequately treated after onset, acute osteomyelitis progresses to a chronic form. The diagnosis of mandibular osteomyelitis rests on processing for identification of microbiologic isolates and on imaging studies to determine the extent of disease. Mandibular osteomyelitis often is associated with involvement of the masticator space and can exhibit symtoms similar to temporomandibular disorder including orofacial pain and limited mouth opening. Advanced imaging modalities can be helpful in obtaining a proper diagnosis.

  • This study aimed to investigate the correlation between the inclinations of the incisors and lips in mixed dentition aged 7 - 11 years. Lateral cephalometric radiographs of 353 children were analyzed to measure the upper incisor inclination, lower incisor inclination, lower-nasolabial angle, and mentolabial angle in relation to the skeletal malocclusion classification. The measurements were then assessed using the Kruskal-Wallis test, Pearson correlation, and multiple regression analysis. There were significant negative correlations between the inclination of the upper incisors and lower-nasolabial angle in all classes of skeletal malocclusion. There was a negative correlation between the inclination of the lower incisors and mentolabial angle; however, class II malocclusion had a significant positive correlation. This study identified the factors that affect lip inclination and verified their associations.

  • Life cycle of Tropidothorax cruciger(Motschulsky) was studied on Cynanchum wilfordii Hemsley in the field as well as its development, overwintering patterns, and host preferences. Overwintered adults appeared in early and mid May, and the first generation adults emerged from late June extending to mid August. Second generation adults which usually overwinter, appeared from mid September to early October and were usually found beneath the soil surface or fallen leaves in winter. Adults were not attracted to various light sources. T. cruciger showed host preferences specifically toward Metapiexis japonica and Cynanchum wilfordii, both in the family of Asclepiadaceae.

  • Pedicularis growing at Mt. Halla of Jeju Island is known as an endemic species of P. hallaisanensis Hurusawa. On the other hand, the plant is morphologically similar to P. amoena, P. spicata, and P. verticillata in gross morphology, so the taxonomic treatment of the taxon remains controversial. To clarify the taxonomic position of the plants, we examined external morphological characters and nuclear ribosomal DNA ITS sequences for P. hallaisanensis and its related species. The plants of Mt. Halla are clearly different from P. amoena and P. verticillata in the morphology of calyx lobes, the length of galea and lower lip, density of glandular hairs on plants, presences of the radical leaves after anthesis and molecular data. However, P. hallaisanensis is not clearly separated from P. spicata distributed in N. E. Asia on external morphological characters and DNA sequences of internal transcribed spacers. In this study, the morphological and molecular data suggested that P. hallaisanensis should be merged into the former species.

  • This study was investigated to elucidate the growth characteristics of Acanthopanax sessiliflorus grown under different conditions and seasons. The emergence percent of seeds sown in the vinyl house was about 2.2 times better than that in the open field. The plants which had 2 to 3 normal leaves showed the highest value in root setting percent, and the root setting percent was decreased significantly in plants with one normal leaf and 4 to 5 normal leaves. The root setting percent of plants transplanted from April 19 to May 2 was 100%, but plants transplanted at April 4 or from May 17 to June 1 showed lower root setting. Tree percent, plant height. root length and fresh weight of plants grown by transplanting culture were better than those of plants grown by direct seeding.

  • The phase and times on the development of dormancy bud in seedling, and those of flower organs in 2-year-old ginseng are different to those of over 2-,3-year-old plant, respectively. The growing aspects of dormancy bud in seedling were investigated from rooting stage (April, 8) to Mid-June, and those of flower organs in 2-year-old plant had done once in two days late in April after compound leaves were unfolded. Firstly, the formation of dormancy bud in seedling was begun on Mid-late in March. This is early about one month compare with those of over 2-year-old plant. Fine bud in seedling was formed between cotyledons, at W spot under young shoot. Secondly, development of flower organs in 2-year-old plant was completed from late of April to early of May after compound leaves of transplanted plant were unfolded. In tare, this is very different characteristics because plants of any other ages form the flower organs one year ago. Thirdly, flower organs of ginseng plant, over 3-year-old plant, always develop in the rhizome formed one year ago, but those of 2-year-old plant develop in apical shoot meristem.
