  • In a essay that was published on 'Science' in December 2014 as a part of the supplement "The Art and Science of Traditional Medicine," the eastern and western medical theories are discussed with reference to the model-dependent realism suggested by Stephen Hawking and Leonard Mlodinow. This paper examines what the model-dependent realism is, and how it affects the future direction of researches in traditional Korean medical theories. The model-dependent realism holds a meaning in that it puts traditional medical theories in a perspective of models, and allows for application of recent studies in scientific philosophy for researches in traditional medical theories. Especially, the model studies by R. Giere et al. will help elaborate the traditional medical theories from a model perspective. From a model perspective, the 'visceral manifestation', 'meridian and collateral', 'qi-blood', 'eight principles' and 'constitution' theories of traditional medicine have the potentials to develop into valid models, and the traditional medical theory's phenomenological and holistic perspective distinguishes it from western medicine, giving it a competitive edge. In addition, the epistemological pluralism of model-dependent realism can serve as an alternative to relativism or rationalism perspective which put eastern and western medicine in opposition until now.

  • Purpose: The purpose of this study was to investigate mothers' knowledge, attitudes, and practices of infection prevention for their children. Methods: In this descriptive study, data were collected using a questionnaire. A total 157 mothers of young children were surveyed regarding their knowledge, attitudes, and practices of infection prevention. Results: The mean score of knowledge, attitudes, and practices of infection prevention in mothers was found to be above average. There were significant differences in knowledge according to whether the mother was employed (t=2.82, p=.005) and in attitudes according to the mother's age (t=2.13, p=.035). In addition, a significant correlation was found between knowledge and attitudes (r=.16, p=.014), and between attitudes and practices (r=.50, p<.001). Conclusion: This research provides baseline information to understand mothers' approaches to infection prevention for their children, and it may serve as a basis for providing educational programs that help infection prevention.

  • A multiplex polymerase chain reaction (PCR) was developed for the simultaneous detection and differentiation among Vairimorpha spp. and Nosema spp. and identification of Vairimorpha necatrix from Lepidoptera insects. Three sets of primers were selected from different genomic sequences to specifically amplify an 831 bp amplicon within the SSU rRNA gene, specific for both Vairimorpha spp. and Nosema spp. (MSSR primer); a 542 bp amplicon within the SSU rRNA gene, specific for Vairimorpha spp. (VSSU primer); and a 476 bp amplicon within the actin gene, specific for Vairimorpha necatrix (VNAG primer). Using the primers in conjunction with multiplex PCR, it was possible to detect Vairimorpha spp. and Nosema spp. and to differentiate between them. The sensitivity of this PCR assay was approximately 10 spores per milliliter. It is proposed that the multiplex PCR is a sensitive, specific, and rapid tool that can serve as a useful differential diagnostic tool for detecting Vairimorpha spp. and Nosema spp. in Lepidoptera insect.

  • Purpose: This study investigates the level of nursing professionalism and factors that affect nurse perceptions. Method: This study is a descriptive study involving 443 nursing students from two universities. Data were collected in September 2012 via a structured self-report questionnaire and subsequently analyzed using descriptive statistics, t-tests, one-way ANOVA, Pearson correlation coefficients, and multiple regression. Results: The mean scores for nurse image, core elements of nursing professionalism and nursing professionalism were $3.65{\pm}.46$, $4.17{\pm}.39$ and $3.59{\pm}.45$, respectively. Nursing Professionalism had a significant positive correlation with nurse image (r=.749, p<.001) and core elements of nursing professionalism (r=.365, p<.001). In multiple linear regression, factors that influenced nursing professionalism were: temperament as nurses, professionalism, vision of career, role performance of nurses' image, and fundamental nursing practical experience. These variables explained about 58.8% of the total variance in nursing professionalism. Conclusion: For more positive nursing professionalism among students, more attention should be paid to enhancing the positive image of nurses. Doing so can serve as a fundamental resource for the development of appropriate strategies for nursing professionalism.

  • We introduce a new project of constructing a large spectro-photometric samples of metal-poor (i.e. [Fe/H] < -1.0) subdwarfs in the Galactic halo. The sample is collected from a compilation of the stellar objects that are cross-identified both in the Sloan Digital Sky Survey (SDSS) and recently published data from GAIA mission. The color range of the selected stars covers 0.0 < (g-r) < 2.0; thus the spectral types of our sample span from early F- through late K-type stars on the metal-poor main sequence (i.e. the local subdwarf sequence). We scrutinized the physical, chemical, and kinematical properties of our samples using their SDSS medium-resolution (R ~ 2000) spectra, combined with accurately measured proper motions from GAIA satellite. Our study will provide useful information on the global trend in the various properties (e.g. abundance pattern as a function of the galactocentric distance; rotational velocity vs [Fe/H] ${\cdots}$ etc) of the metal-poor subdwarf populations in the Galactic halo, which is ultimately important to better understand metal-poor stellar evolutionary models and chemical evolution of the Milky Way halo in the early phase of its formation. Further our comprehensive catalog of the Galactic field halo subdwarfs collected in this study will serve a solid groundwork for future follow-up high resolution spectroscopic observations on many interesting individual targets.

  • This research was conducted to estimate the chlorophyll contents of chrysanthemum leaves using SPAD-502 chlorophyll meter under different photoperiod and light intensity. Measurements were done at every third leaf intervals starting from the top of the stem to the bottom at harvest time. SPAD value was highest at 10 hours of photoperiods, followed by 13 and 16 hours of photoperiods. In particular, under short day condition, SPAD value was highest in the young leaves below the flower bud and decreased down the leaf profile. Under long day condition, SPAD value reached maximum at leaves between $15-27^{th}$ from the top and decreased to the minimum immediately below the flower bud (youngest leaf). These results may indicate that the younger leaves become strong source of supporting flowers in reproductive stage, while the younger leaves serve as sinks and older leaves support their development in vegetative stage. Changes of SPAD value at different levels of irradiance showed that highest SPAD value were observed at high irradiance and decreased with decreasing irradiance.

  • C. sinensis total RMh was containing large amount of 185 rRNA but little 285 rRNA. The size of the double-stranded cDNA synthesized from poly $(A)^{+}$ mRNA was 0.4-4.2 kb long with tapering unto 9.5 kb. Degenerated oligonucleotides (as 2 sense and 3 antisense Primers) were designed on the conserved regions of the known tropomyosin amino acid sequences. From one out of the PCR amplifications using total CDNA and matrix of primers, a specific gene product, 580 bp in size, was produced. Upon Southern hybridization of the PCR products with Schistosomn mnnsoni tropomyosin (SMTM) CDNA, only one signal appeared at the band of 580 bp product. This 580 bp product was considered to encode C. sinensis tropomyosin (CSTM) and cloned in pGEM-3Zf(-) for DNA sequencing. CSTM cDNA was 575 bp containing one open reading frame of 191 predicted amino acids, which revealed 86.3% homology with SMTM and 51.1% with rrichostronsylur coeubnlormis tropomyosin. CSTM cDNA obtained will serve as a probe in the studies of molecular cloning of CSTM.

  • Outdoor copper alloy is exposed to the atmospheric environment, accelerating corrosion progress compared with indoor copper alloy. In order to prevent corrosion, the outdoor copper alloy is coated with wax to block external corrosion factors. However, corrosion of the inside of the coating film is highly likely to continue without the internal corrosion prevention treatment. B.T.A, which is used as a copper alloy water-soluble corrosion inhibitor, has a high possibility of being harmful to the human body and is mainly used to treat excavated artifacts. This study had selected the water-soluble corrosion inhibitor, which was easier to use than the existing wax and B.T.A being used in corrosion inhibition treatment for outdoor copper alloy. A comparative study was conducted on B.T.A, which is a water-soluble corrosion inhibitor used on excavated artifacts, and $VCI^{(R)}$, $Rus^{(R)}$, and L-cys, an amino acid corrosion inhibitor, used for tin bronze test pieces. The experimental method was conducted for a certain period of time with the salt, acid, and air pollution affecting the corrosion of outdoor copper alloy. Based on experiment results, it was concluded that the best water - soluble copper alloy corrosion inhibitor in the atmospheric environment is $VCI^{(R)}$. and it could be considered to be applied in replacement of B.T.A due to its low harmfulness. In addition, $VCI^{(R)}$ is judged to serve as a corrosion inhibitor for outdoor copper alloy because it showed the best result even in the outdoor exposure test which is a real atmospheric environment.
