Y. J. KIM, J. G. JI, J. T. KIM, J. H. HONG, J. S. LEE, H. S. LEE, S. B. PARK. A comparison study for mask plantar pressure measures to the difference of shoes in 20 female. Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 83-98, 2004. The purpose of this study was to investigate the test-retest of plantar pressures using the F-Scan system over speeds and plantar regions. 6 healthy female subjects in 20's were recruited for the study. Plantar pressure measurements during locomotor activities can provide information concerning foot function, particularly if the timing and magnitude of the loading profile can be related to the location of specific foot structures such as the metatarsal heads. The Tekscan F-Scan system consists of a flexible, 0.18mm thick sole-shape having 1260 pressure sensors, the sensor insole was trimmed to fit the subjects' right. left shoes - sneakers shoes & dress shoes. It was calibrated by the known weight of the test subject standing on one foot. The Tekscan measurements show the insole pressure distribution as a function of the time. This finding has important implications for the development of plantar pressure test protocols where the function of the forefoot is important. According to the result of analysis it is as follows : 1) Center of force trajectory in women's dress shoes display direct movement, compare with center of force trajectory in Sneaker shoes displays a little bit curved slow pronation movement. Sneaker shoes in forefoot part display very quick supination movement, therefore, this shoes effects negative effectiveness for ankle's stability. Considering center of force trajectory analyzing, the more center of force close straight line, the more movement can be quick movement for locomotion. For foot pressure distribution, center of force trajectory in locomotion is better to curved trajectory with pronation movement. So sneaker shoes style is good shoes considering center of pressure distribution trajectory compare with women's dress shoes. 2) Women's dress shoes increased peak pressure in medial, this is effected by high hill's height. The more increased women's dress shoes's height, the more women's peak pressure will increase, pronation can increase compare with before. Supination movement increase, this focused pressure in lateral, also, supination increased more. If the supination movement increased, foot pressure focused in lateral, therefore, it is appeared force distribution in gait direction. This is bad movement in foot's stability. 3) Women's dress shoes in landing phase displayed a long time, this is when women's dress shoes wear, gait movement is unbalance, so, landing phase displayed a long time. For compensation in gait, swing phase quick movement. 4) Women's dress shoes displayed peak pressure distribution in lateral of rearfoot part, Sneakers shoes displayed peak pressure distribution in medial of forefoot part. Its results has good impact absorption compare with women's dress shoes. In forefoot part, sneakers shoes has good propulsive force compare with women's dress shoes.

Identification of Range Overlaid Echoes Using Polarimetric Radar Measurements Based on a Fuzzy Logic Approach

Park, S.-G.,Kim, Ji-Hyeon,Ko, Jeong-Seok,Lee, Gyuwon AMERICAN METEOROLOGICAL SOCIETY 2016 Journal of atmospheric and oceanic technology Vol.33 No.1

<P>The Ministry of Land, Infrastructure and Transport (MOLIT) of South Korea operates two S-band dual-polarimetric radars, as of 2013, to manage water resources through quantitative rainfall estimations at the surface level. However, the radar measurements suffer from range ambiguity. In this study, an algorithm based on fuzzy logic is developed to identify range overlaid echoes using seven inputs: standard deviations of differential reflectivity SD(Z(DR)), differential propagation phase SD(phi(DP)), correlation coefficient SD(rho(HV)) and spectrum width SD(sigma(v)), mean of rho(HV) and sigma(v), and difference of phi(DP) from the system offset Delta phi(DP). An examination of the algorithm's performance shows that these echoes can be well identified and that echoes strongly affected by second trip are highlighted by high probabilities, over 0.6; echoes weakly affected have probabilities from 0.4 to 0.6; and those with low probabilities, below 0.4, are assigned as echoes without range ambiguity. Aquantitative analysis of a limited number of cases using the usual skill scores shows that when the probability of 0.4 is considered as a threshold for identifying the range overlaid echoes, they can be identified with a probability of detection of 90%, a false alarm rate of 6%, and a critical success index of 84%.</P>

Rgs19 regulates mouse palatal fusion by modulating cell proliferation and apoptosis in the MEE

Sohn, W.J.,Ji, Y.R.,Kim, H.S.,Gwon, G.J.,Chae, Y.M.,An, C.H.,Park, H.d.,Jung, H.S.,Ryoo, Z.Y.,Lee, S.,Kim, J.Y. Elsevier Scientific Publishers Ireland 2012 Mechanisms of development Vol.129 No.9

Palatal development is one of the critical events in craniofacial morphogenesis. During fusion of the palatal shelves, removal of the midline epithelial seam (MES) is a fundamental process for achieving proper morphogenesis of the palate. The reported mechanisms for removing the MES are the processes of apoptosis, migration or general epithelial-to-mesenchymal transition (EMT) through modulations of various signaling molecules including Wnt signaling. RGS19, a regulator of the G protein signaling (RGS) family, interacts selectively with the specific α subunits of the G proteins (Gαi, Gαq) and enhances their GTPase activity. Rgs19 was reported to be a modulator of the Wnt signaling pathway. In mouse palatogenesis, the restricted epithelial expression pattern of Rgs19 was examined in the palatal shelves, where expression of Wnt11 was observed. Based on these specific expression patterns of Rgs19 in the palatal shelves, the present study examined the detailed developmental function of Rgs19 using AS-ODN treatments during in vitro palate organ cultivations as a loss-of-function study. After the knockdown of Rgs19, the morphological changes in the palatal shelves was examined carefully using a computer-aided three dimensional reconstruction method and the altered expression patterns of related signaling molecules were evaluated using genome wide screening methods. RT-qPCR and in situ hybridization methods were also used to confirm these array results. These morphological and molecular examinations suggested that Rgs19 plays important roles in palatal fusion through the degradation of MES via activation of the palatal fusion related and apoptotic related genes. Overall, inhibition of the proliferation related and Wnt responsive genes by Rgs19 are required for proper palatal fusion.

Purpose: The purpose of this study was to provide basic data for use in the upgrade of healthcare for the elderly and to provide guidance toward educating the elderly in the proper use of medications by determining the level of drug knowledge, current use, and adherence by the elderly. Method: The participants of this study were selected using the convenient sampling method. Participants of this study comprised of 160 elderly who were aged 65 or older, who were participants to the elderly municipal welfare center in Seoul. The instrument used for this study was a structured questionnaire (Han,2011). Collected data were analyzed using the SPSS20.0 program with descriptive statistics, t-test, ANOVA, and Pearson’s correlation coefficient. Result: The mean score for drug knowledge was 7.6±2.9 and drug misuse was 4.7±2.8. There were significant differences about drug knowledge according to the following: level of education (F=8.053 p=.000), and spouse (t=2.14 p=.034). There were significant differences between drug misuse and monthly income (F=2.167 p=.040). There was no statistically significant relationship between drug knowledge and drug misuse (r=-.087, p=.271). Conclusion: A replication study based on broader region and in-depth research is needed. The development of the customized education protocol considering various levels of education, income, spouse and physical condition are needed. Further research is suggested to find out the status of medication education for the elderly by nurses.

Direct analysis of site-specific N-glycopeptides of serological proteins in dried blood spot samples

Choi, N. Y.,Hwang, H.,Ji, E. S.,Park, G. W.,Lee, J. Y.,Lee, H. K.,Kim, J. Y.,Yoo, J. S. Springer Science + Business Media 2017 Analytical and Bioanalytical Chemistry Vol.409 No.21

<P>Dried blood spot (DBS) samples have a number of advantages, especially with respect to ease of collection, transportation, and storage and to reduce biohazard risk. N-glycosylation is a major post-translational modification of proteins in human blood that is related to a variety of biological functions, including metastasis, cell-cell interactions, inflammation, and immunization. Here, we directly analyzed tryptic N-glycopeptides from glycoproteins in DBS samples using liquid chromatography-tandem mass spectrometry (LC-MS/MS) without centrifugation of blood samples, depletion of major proteins, desalting of tryptic peptides, and enrichment of N-glycopeptides. Using this simple method, we identified a total of 41 site-specific N-glycopeptides from 16 glycoproteins in the DBS samples, from immunoglobulin gamma 1 (IgG-1, 10 mg/mL) down to complement component C7 (50 mu g/mL). Of these, 32 N-glycopeptides from 14 glycoproteins were consistently quantified over 180 days stored at room temperature. The major abundant glycoproteins in the DBS samples were IgG-1 and IgG-2, which contain nine asialo-fucosylated complex types of 16 different N-glycopeptide isoforms. Sialo-non-fucosylated complex types were primarily detected in the other glycoproteins such as alpha-1-acid glycoprotein 1, 2, alpha-1-antitypsin, alpha-2-macroglobulin, haptoglobin, hemopexin, Ig alpha 1, 2 chain C region, kininogen-1, prothrombin, and serotransferrin. We first report the characterization of site-specific N-glycoproteins in DBS samples by LC-MS/MS with minimal sample preparation.</P>

Characteristics and composition of atmospheric aerosols in Phimai, central Thailand during BASE-ASIA

Li, C.,Tsay, S.C.,Hsu, N.C.,Kim, J.Y.,Howell, S.G.,Huebert, B.J.,Ji, Q.,Jeong, M.J.,Wang, S.H.,Hansell, R.A.,Bell, S.W. Pergamon Press ; Elsevier [distribution] 2013 Atmospheric environment Vol.78 No.-

Comprehensive measurements of atmospheric aerosols were made in Phimai, central Thailand (15.183<SUP>o</SUP>N, 102.565<SUP>o</SUP>E, elevation: 206 m) during the BASE-ASIA field experiment from late February to early May in 2006. The observed aerosol loading was sizable for this rural site (mean aerosol scattering: 108 +/- 64 Mm<SUP>-1</SUP>; absorption: 15 +/- 8 Mm<SUP>-1</SUP>; PM<SUB>10</SUB> concentration: 33 +/- 17 μg m<SUP>-3</SUP>), and dominated by submicron particles. Major aerosol compounds included carbonaceous (OC: 9.5 +/- 3.6 μg m<SUP>-3</SUP>; EC: 2.0 +/- 2.3 μg m<SUP>-3</SUP>) and secondary species (SO<SUB>4</SUB><SUP>2-</SUP>: 6.4 +/- 3.7 μg m<SUP>-3</SUP>, NH<SUB>4</SUB><SUP>+</SUP>: 2.2 +/- 1.3 μg m<SUP>-3</SUP>). While the site was seldom under the direct influence of large forest fires to its north, agricultural fires were ubiquitous during the experiment, as suggested by the substantial concentration of K<SUP>+</SUP> (0.56 +/- 0.33 μg m<SUP>-3</SUP>). Besides biomass burning, aerosols in Phimai during the experiment were also strongly influenced by industrial and vehicular emissions from the Bangkok metropolitan region and long-range transport from southern China. High humidity played an important role in determining the aerosol composition and properties in the region. Sulfate was primarily formed via aqueous phase reactions, and hygroscopic growth could enhance the aerosol light scattering by up to 60%, at the typical morning RH level of 85%. The aerosol single scattering albedo demonstrated distinct diurnal variation, ranging from 0.86 +/- 0.04 in the evening to 0.92 +/- 0.02 in the morning. This experiment marks the first time such comprehensive characterization of aerosols was made for rural central Thailand. Our results indicate that aerosol pollution has developed into a regional problem for northern Indochina, and may become more severe as the region's population and economy continue to grow.

Ji, A.G.,Huai, Y.H.,Zhou, Z.K.,Li, Y.J.,Zhang, L.P.,Xu, S.Z.,Gao, X.,Ren, H.Y.,Chen, J.B. Asian Australasian Association of Animal Productio 2008 Animal Bioscience Vol.21 No.8

Paraoxonase-1 (PON1), like lipoprotein lipase (LPL), plays a key role in the metabolism and physiology of mammalian growth. The objectives of this study were to estimate the allele and genotype frequencies at the PON1/EcoRV and PON1/AluI loci in three genetic groups of beef cattle and to determine associations between these polymorphisms and growth and carcass traits. Genotyping was performed on 30 Angus, 32 Hereford and 26 Simmental. The association analysis was carried out using the GLM procedure of SAS 9.1 and the least squares means of the genotypes were compared by the Tukey's test. Animals with AG genotype at the PON1/EcoRV locus had higher weight at the time of entry into the fattening corrals ($329.97{\pm}6.08kg$) and close to the time of slaughter ($577.56{\pm}8.32kg$) and net meat weight ($275.89{\pm}4.05kg$) and fitted tenderness ($3.10{\pm}0.19kg$) (p<0.05). Animals with AA genotype at the PON1/AluI locus had higher weight at the time of entry ($333.37{\pm}8.93kg$) and slaughter ($576.82{\pm}13.18kg$) and net meat weight ($275.49{\pm}6.43kg$) and average daily gain ($0.68{\pm}0.02kg/d$) (p<0.05). The meat color score was also significantly higher (p<0.05). Between genotypes and breeds, there were significant differences observed except for TBW, REMG, MBS, REA and MCS. As a metabolism gene, genotypes of the SNPs of PON1 gene might be reflecting BFT directly, such as $A_eA_eG_aG_a$ genotype in this experiment.
