A plant-specific gene was cloned from melon fruit. This gene was named downward leaf curling (CmDLC) based on the phenotype of transgenic Arabidopsis plants overexpressing the gene. This expression level of this gene was especially upregulated during melon fruit enlargement. Overexpression of CmDLC in Arabidopsis resulted in dwarfism and narrow, epinastically curled leaves. These phenotypes were found to be caused by a reduction in cell number and cell size on the adaxial and abaxial sides of the epidermis, with a greater reduction on the abaxial side of the leaves. These phenotypic characteristics, combined with the more wavy morphology of epidermal cells in overexpression lines, indicate that CmDLC overexpression affects cell elongation and cell morphology. To investigate intracellular protein localization, a CmDLC-GFP fusion protein was made and expressed in onion epidermal cells. This protein was observed to be preferentially localized close to the cell membrane. Thus, we report here a new plant-specific gene that is localized to the cell membrane and that controls leaf cell number, size and morphology.

The purpose of this study is to suggest the sizing system of medical compression stockings for Korean adult men in order to develop compression stockings with excellent dimensional fit reflecting the real human body data. Analyses were conducted on the raw data that the subjects consist of 19~60 aged men of Size Korea 2010 in this study. The stature and weight for the pantyhose stockings, and the ankle circumference and calf circumference for the thighs, knees, and calf support types of stockings were selected as the basic dimension items. The size interval of the pantyhose stockings were 2cm in stature and 2kg in weight. In addition, the thigh, knee, and calf support types of stockings were set with ankle circumference and calf circumference set at 1cm intervals. The designation is the same as KS pantyhose standard, S, M, L, XL. As a result, in the case of pantyhose compression stockings for men, the coverage ratio showed 97.2% in total, with 46.3% for M, 36.5% for L, 7.4% for S, and 6.9% for XL. In the case of thigh type, knee type and calf support types, the percentage of coverage was 99.96% in total, with 57.6% in M, 31.1% in L, 4.7% in S, and 1.6% in XL. The results of this study would help to improve the dimensional conformity of the medical compression stockings for Korean adult men.

Korea is presently the leading country in global desalination industry and has been investing a large amount of money and human resources in development of new core technologies to increase its' share of global market. In this paper, we reviewed world-wide trends of the advanced water industry and outlined various seawater desalination technologies developed so far. We also made some analysis on the directions and results of the government-lead R&D sponsorship in the field of seawater-freshening technology. Present studies showed that we need an institutional strategy to help domestic companies guarantee the credibility of the technologies developed by themselves based upon their experience of plant operation. Futhermore, strategic R&D programs to develope original technologies and localization of key components for desalination plants should be preceded in the near future.

Intracellular organelles in eukaryotic cells play important roles in many cellular functions. Intracellular trafficking of many proteins to specific intracellular organelles is tightly regulated by various mechanisms in cells. Therefore, elucidating the targeting mechanism of novel markers for intracellular organelles is important for cellular physiology and pathology. In this study, we tried to identify the peptides which could bind to specific glycolipid in cellular membrane using GFP-fused glycolipid-binding peptides, and analyzed their cellular localization. As a result, we could identify mitochondria-, Golgi- or plasma membrane-targeting peptides. Furthermore, we found that the plasma membrane-targeting peptide was localized to the plasma membrane via electrostatic interactions. Thus, our results suggest that various glycolipid-binding peptides could be used as intracellular organelles markers.

This study have goal with conceptual design for Offshore Structures of high pressure control valve for localization. Ball valve for development accomplished with flow analysis based on provision of ANSI B16.34, ANSI B16.10, ANSI B16.25 In order to localize the Offshore Structures high pressure control valve. Numerical simulation using CFD(Computational Fluid Dynamic) in order to predict a mass flow rate and a flow coefficient form flow dynamic point of view. The working fluid assumed the glycerin($C_3H_8O_3$). The valve inlet and outlet setup a pressure boundary condition. The outlet pressure was fixed by atmospheric pressure and calculated until increasing 1bar to 10bar. CFD analysis used STAR-CCM+ which is commercial code and Governing equations were calculated by moving mesh which is rotated 90 degrees when ball valve operated opening and closing in 1 degree interval. The result shows change of mass flow rate according to opening and closing angle of valve. Flow decrease observed open valve that equal percentage flow paten which is general inclination of ball valve. Relation with flow and flow coefficient can not be proportional according to inlet pressure when compare with mass flow rate. Because flow coefficient have influence in flow and pressure difference. Namely, flow can be change even if it has same Cv value. The structural analysis used ANSYS which is a commercial code. Stress analysis result of internal pressure in valve showed lower than yield strength. This is expect to need more detail design and verification for stem and seat structure.

Formation, cellular distribution and structural changes of storage lipid, and active site and cellular localization of lipase in endosperms and cotyledons of lipid-rich seeds such as Helianthus annuus, Ricinus communis and Pinus koraiensis, and in those of starch-rich seeds such as Pisum sativum and Zea mays were investigated in relation to the seed development by cytochemical methods. In endosperms and storage cotyledons of lipid- and starch-rich seeds after seed-gathering, there were widely distributed storage material which was composed of spherical protein bodies, spherosomes, and starch granules. But cellular organelles were hardly observed in the cytoplasm. Staining pattern of vesicles released from SER, and of low electron dense membraneous granules, which were perhaps at an early stage of spherosomes, were the same as in the spherosome. Electrondense granules released from RER were observed in the vicinity of plasma membrane. As a result of lipid staining, the spherosomes were more electron dense and were uniform as compared with the protein matrix within the protein body and cytoplasmic proteinaceous granules. The major component of the spherosome was determinated to be lipid. Spherosomes and vesicles containing SER-released materials showed the same as in the electron density. Lipase activity was especially strong in the inner region and on the surface of decomposed spherosomes and near the plasma membrane.mbrane.

According to the development of streaming services with P2P and mobile network technologies, researches to enhance the service quality in mobile environment have been proposed. However, streaming services considering high-speed mobile environment and characteristics of heterogenous terminals have been hindered from being provided with the required quality from user because of bandwidth congestion between selfish peers of existing P2P system. It is also prone to long delay and loss in accordance with the repeated traffic amounts because there are no optimized solution for traffic localization. The structure to enhance peer contribution for service differentiation and peer selection with clustering scheme with location information of terminal can satisfy both users and service providers with service quality and efficiency. In this paper, we propose an incentive mechanism and resource distribution scheme with user contribution and traffic cost information based on user location, which make mobile users increase the satisfaction of service quality in LTE environments.
