  • This study is concerned with a comparative linguistic analysis of the Mongolian costume terminologies. It was found that the Mongolian costume terminologies were related to the costume terminologies of English, Indian, Chinese, Arabic Uigur, Tibetan, Persian, Turkish, Hebrew, Assyrian. The influence of the Chinese costume terminologies was fond in the terminologies of the fabrics and the precious stones of the Mongolians. Also, the influence of the Indian costume terminologies were shown in the Mongolian costume terminologies. A characteristic feature in the Mogolian costume terminologies of the fabrics and the precious stones showed the elements of the foreign terminologies. This factor amy be due to the fact that originally the Mongolians ere the nomades.

  • Enteromorpha polysaccharides (EP) extracted from green algae have displayed a wide variety of biological activities. However, their high molecular weight leads to a high viscosity and low solubility, and therefore, greatly restrains their application. To solve this problem, bacteria from the surface of Enteromorpha were screened, and an Alteromonas macleodii strain B7 was found to be able to decrease the molecular weight of EP in culture media. Proteins harvested from the supernatant of the A. macleodii B7 culture were subjected to native gel electrophoresis, and a band corresponding to the Enteromorpha polysaccharide lyase (EPL) was detected by activity staining. The enzyme identity was subsequently confirmed by MALDI-TOF/TOF mass spectrometry as the putative ${\alpha}$-amylase reported in A. macleodii ATCC 27126. The amylase gene (amySTU) from A. macleodii B7 was cloned into Escherichia coli, resulting in high-level expression of the recombinant enzyme with EP-degrading activity. AmySTU was found to be cold-adapted; however, its optimal enzyme activity was detected at $40^{\circ}C$. The ${\alpha}$-amylase was highly stable over a broad pH range (5.5-10) with the optimal pH at 7.5-8.0. The highest enzyme activity was detected when NaCl concentration was 2%, which dropped by 50% when the NaCl concentration was increased to 16%, showing an excellent nature of halotolerance. Furthermore, the amylase activity was not significantly affected by tested surfactants or the presence of some organic solvents. Therefore, the A. macleodii strain B7 and its ${\alpha}$-amylase can be useful in lowering EP molecular weight and in starch processing.

  • Leuconostoc mesenteroides SY1, a strain isolated from cabbage Kimchi, was transformed with pCW4, a shuttle vector based on a cryptic plasmid from Lactobacillus paraplantarum C7. $\alpha-Amylase$ gene, amyL, from Bacillus licheniformis was cloned into pCW4, resulting in $pCW4T{\alpha},\;and\;pCW4T{\alpha}$ was introduced into SY1 by electroporation. Transformation efficiency was $10^2cells/{\mu}g$ plasmid DNA. L. mesenteroides cells harboring $pCW4T{\alpha}$ did not show amylase activity, although amyL transcript was synthesized as determined by slot blot experiment. $pCW4T{\alpha}$ was stably maintained in SY1 in the presence of erythromycin (Em, $5\;{\mu}g/ml$) but rapidly lost when Em was omitted. Less than $1\%$ of the cells maintained $pCW4T{\alpha}$ after 5 days at $30^{\circ}C$.

  • A new poinsettia cultivar 'Noel' was bred by the National Institute of Horticultural and Herbal Science(NIHHS) in 2007. In 2004, a cross was made between 'Gutbier V-10 Amy', a variety with high free-branching habit and light red bracts, and 'Ichiban', a variety with deeply lobed transitional leaves and bright red bracts. 'Noel' was finally selected in 2007 after the investigation of observations on the growth and flower characteristics from 2005 to 2007. 'Noel' has smoothly waving red elliptic bracts. Leafblades are dark green and ovate. The variety has relatively long petioles, and stem color is greenish. 'Noel' has high free-branching ability and plant height is medium. Noel's bracts and transitional leaves are fully colored in 7.5 weeks after short day treatment.

  • Phospholipase D has great commercial value due to its transphosphatidylation products that can be used in the food and medicine industries. In order to construct a strain for use in the production of PLD, we employed a series of combinatorial strategies to increase PLD expression in Bacillus subtilis WB600. These strategies included screening of signal peptides, selection of different plasmids, and optimization of the sequences of the ribosome-binding site (RBS) and the spacer region. We found that using the signal peptide amyE results in the highest extracellular PLD activity (11.3 U/ml) and in a PLD expression level 5.27-fold higher than when the endogenous signal peptide is used. Furthermore, the strain harboring the recombinant expression plasmid pMA0911-PLD-amyE-his produced PLD with activity enhanced by 69.03% (19.1 U/ml). We then used the online tool \RBS Calculator v2.0 to optimize the sequences of the RBS and the spacer. Using the optimized sequences resulted in an increase in the enzyme activity by about 26.7% (24.2 U/ml). In addition, we found through a transfer experiment that the retention rate of the recombinant plasmid after 5 generations was still 100%. The final product, phosphatidylserine (PS), was successfully detected, with transphosphatidylation selectivity at 74.6%. This is similar to the values for the original producer.

  • Studies of prosody and sentence processing have demonstrated that prosodic phrasing can exhibit strong effects on processing decisions in English. In this paper, we tested Korean sentence fragments containing syntactically ambiguous Adj-N1-N2 strings in a cross-modal naming task. Four accentual phrasing patterns were tested: (a) the default phrasing pattern, in which each word forms an accentual phrase; (b) a phrasing biased toward N1 modification; (c) a phrasing biased toward complex-NP modification; and (d) a phrasing used with adjective focus. Patterns (b) and (c) are disambiguating phrasings; the other two are commonly found with both interpretations and are thus ambiguous. The results showed that the naming time of items produced in the prosody contradicting the semantic grouping is significantly longer than that produced in either default or supporting prosody, We claim that, as in English, prosodic information in Korean is parsed into a well-formed prosodic representation during the early stages of processing. The partially constructed prosodic representation produces incremental effects on syntactic and semantic processing decisions and is retained in memory to influence reanalysis decisions.

  • As needs for telecommunications services diversify, an increasingly wide range of telecommunications services is becoming available in the market. Any subscriber can find a service to satisfy his/her telecommunication requirements and competition between providers to retain heavy users is increasing. Service price reductions are one retention strategy, although price reductions for one service can affect the individual-level usage for other services. Price reductions can also be imposed on a service provider by regulation. For these reasons, understanding how price reductions affect service usage is of growing importance to the telecommunications industry for purposes of pricing and tariff development. In this paper, we develop an individual-level usage model for telecommunications services and analyze the effects on usage of a price reduction. We apply the model to age-stratified aggregate traffic data for a Korean mobile telecommunication service provider. Finally, we develop a model to support a market segmentation and price reduction strategy.

  • We have constructed a scanning confocal microscope by directly oscillating an optical fiber in two different ways. Either a piezoelectric transducer or a tuning fork was used for the oscillation. Six frames of $640{\times}480$ pixel image were obtained in a second with piezoelectric oscillation and only one image of the same size was obtained in a second with tuning fork oscillation. Oscillation of optical fiber did not cause amy distortion of confocal images.
