  • We have studied the phase transition to look for molecular structure by using several different techniques for new banana-shaped liquid crystals shown in Fig. 1. Based on the similarities to recently observed fluro-contaning materials (switching involves layer structure rearrangement, increasing threshold with increasing temperature) for HC sample (where x is H), we assume that the phase C has a triclinic symmetry corresponding to the double tilted $smC_G$ Phase. The observation that the polarization peak appears at lower field ($E_o{\sim}15V/{\mu}m$) than the amplitude of the threshold ($E_{th}$) can be explained assuming a field induced $SmC_G$ - SmCP (or SmAP) transition at $E_{th}$

  • Considering that the layered cellular automata (LCA) are naturally fit for representing image data in various applications, a novel reverse iterative image encryption scheme based on LCA is proposed. Specifically, the plain image is set as the final configuration of an 8-layer CA, and some sequences derived from a random sequence are set as the pre-final configuration, which ensure that the same plain image will never be encrypted in the same way when encrypted many times. Then, this LCA is backward evolved by following some reversible two order rules, which are generated with the aid of a newly defined T-shaped neighborhood. The cipher image is obtained from the recovered initial configuration. Several analyses and experimental results show that the proposed scheme possesses a high security level and executive performance.

  • Numerical simulation is one of the most useful tools to study gas discharge phenomena that occur in alternating current plasma display panel (AC-PDP) cell. Most PDP cell simulations have been performed for two-dimensional cell, is cross-section along the address electrode. We developed a three-dimensional PDP simulator and applied it to a T-shaped electrode cell in order to show the effects of sustain electrode shape that cannot be included in two-dimensional simulation. The dependence of power consumption on electrode shape and area in the simulation showed the same trend as experiment.

  • Hetero-dimer anions of naphthalene (Np), anthracene (An), phenanthrene (Ph) and pyrene (Py) were investigated using the time-of-flight mass spectrometer (TOF-MS), anion photoelectron spectroscopy (PES) and theoretical calculation. There are two possible geometries with their electron affinity (EA) difference: parallel displaced (PD) and T-shaped. Dispersion force plays a key role in PD structure with the formation of a new anionic core while ${\pi}$-hydrogen interaction plays a key role in T-shaped structure with the monomer anionic core. The optimized structures and charge distributions can simply be explained by the relative difference of EA.

  • In this paper, we have designed and fabricated a BPF (Band Pass Filter) for 5.8GHz Microwave Wireless Power Transmission. We $used{\lambda}g/2$ open-circuited stubs in addition to T-shaped transmission lines for the BPF. This BPF removes harmonics caused by diodes of RF-DC converter, and thus the RF-DC converter converts more RF power to the DC. The performance of the BPF was measured and shown through direct comparison of voltages converted by the doubler as a RF-DC Converter with and without the BPF.

  • This paper addresses a fundamental and theoretical model for the shape of a cucumber and its human-oriented proper definition of length and curvature in order to sort cucumbers electronically. In addition, we design a T-shaped array of sensors to minimize the number of sensors and the processing number of A/D(Analog/Digital) conversions, and we analyze regular patterns of a series of 1's and 0's which are converted from an A/D module. Finally we suggest an algorithm for measuring the length and curvature providing a rule from the regular patterns. The methodology suggested in this paper could be applied to electronical classification of some crops and fruits such as tomatoes, apples, and so on, and can be a basis for developing other sorting machines.

  • Five bacterial strains, ES10-3-3-1, KKM10-2-2-1, Ant11, JM10-4-1-3, and KMS4-11 assigned to the genus Deinococcus were isolated from soil samples collected from Namyangju-si in Gyeonggi-do, Gangnam-gu and Dongdaemun-gu in Seoul, Korea. In addition, four bacterial strains, KKM10-2-7-2, JM10-2-5, JM10-2-6-2, and KKM10-2-3 assigned to the genus Hymenobacter were isolated from soil samples collected from Gangnam-gu and Dongdaemun-gu in Seoul, in South Korea. The five Deinococcus species were Gram-stain positive, pink-pigmented, and short-rod or coccus shaped. The four Hymenobacter species were Gram-stain negative, red-pigmented, and short-rod shaped. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strains ES10-3-3-1, KKM10-2-2-1, Ant11, JM10-4-1-3, and KMS4-11 were most closely related to Deinococcus citri $NCCP-154^T$ (with 99.8% similarity), Deinococcus grandis DSM $12784^T$ (99.0%), Deinococcus marmoris DSM $12784^T$ (98.8%), Deinococcus claudionis $PO-04-19-125^T$ (98.7%), and Deinococcus radioresistens $8A^T$ (99.8%), respectively. KKM10-2-7-2, JM10-2-5, JM10-2-6-2, and KKM10-2-3 were most closely related to Hymenobacter algoricola $VUG-A23a^T$ (99.1% similarity), Hymenobacter elongatus $VUG-A112^T$ (99.1% similarity), Hymenobacter gelipurpurascens $Txg1^T$ (99.1% similarity), and Hymenobacter psychrotolerans $Tibet-IIU11^T$ (99.3% similarity), respectively. These nine species have never been reported in Korea; thus, five Deinococcus species are reported in the family Deinococcaceae, order Deinococcales, class Deinococci, phylum Deinococcus-Thermus and four Hymenobacter species are reported in the family Cytophagaceae, order Cytophagales, class Cytophagia, phylum Bacteroidetes.

  • The purpose of this study is to comprehend strengthening Hwaban(flower-shaped support) design in the Two-lkgong style government buildings in the late Joseon period through the T-shaped wooden shrines, the architectures of royal palace and royal ancestral shrine. Following conclusions have been reached through the study. First, Janghwaban(the long plate carved with flower-shaped support) was installed in Injeongjeon(1805) for the first time. It took 40 years to introduce Janghwaban to the government building of Two-lkgong style compared with Injeongjeon. Second, the quantity of Hwaban had been increased from 1 to 5 for 300 years in the government building of Two-lkgong style. This had been steadily increased with the aim of strengthening design. Third, there was a limit to the increase in the quantity of Hwaban. The first reason was to control the rhythm between the Hwaban and the Pobyeok(the wall between Hwabans). The second reason was that if the Pobyeok was too narrow, it was difficult to plaster. The latter was solved by introducing the Janghwaban. Fourth, in attempting to stylize differently from Jusimpo(simple bracket system), the quantity of Hwaban increase played a very important role in the government building of the Two-lkgong style. Since the reconstruction of Gyeongbokgung Palace, Hwaban combined style with Ungong served as the norm of the royal palace architecture in the last Joseon period.

  • This study provides suggestions of cultural product design contents by using the cloud-shaped gong in traditional temple culture in order to find a high value-added approach. The research herein is part of cultural design contents projects embedded with the spiritual value and symbolic connotation of temple culture. This would be meaningful to enhance its degree of utilization. This can also be a way to find a strategic alternative to a high value addition of temple stay and dissemination of temple culture. For the research methodology, literature was reviewed over temple stay and Bulgeonsamul. For motive design and development of cultural product design, both Adobe Illustrator CS3 and Adobe Photoshop CS3 were used as computer design program. The template image of cloud-shaped gong for basic motive design was selected from those available at the domestic temples for accurate depiction of its head and body. Finally, samples were adopted from those temples of Gounsa, Songgwangsa, Guinsa, Hwaeomsa, and Naesosa. For each motive, different colors were applied and ten basic motives were practiced in total. By repeating the process for these motives, three types of textile design were prepared. T-shirt designs used a round neckline as basic form, and it was designed for sleeved and sleeveless styles. Apron designs stressed V-neckline and two types were processed: one for the back seam line and the other for side seam line. Pendants were designed with modern and luxurious image so that so that it could be used in various types of accessories. Designs for the bedding applied pattern design of the motives and this was done in a way that gave the images a sense of stability and splendor.
