Analysis of Low Amylose and Processability Fractured Endosperms Derived from Somatic Variation  [PDF]
Gihwan Yi, Kyung Min Kim
Food and Nutrition Sciences (FNS) , 2013, DOI: 10.4236/fns.2013.46A003
Abstract: Recently, improving eating quality and processing properties has become one of the most important objectives in japonica rice breeding programs in Korea. This study was carried out to determine the agronomy and physicochemical characteristics of the opaque endosperm rice \"S-21-3-8\" regenerated from seed-derived callus culture of a rice cultivar, \"Ilpum\". S3 generation of opaque endosperm mutants selected from pedigree breeding was used for analysis of agronomic and physicochemical traits. Genetic segregation was observed at the highest frequency among opaque endosperm mutants, being present in 85.7% (12/14 lines) of the entire opaque lines. However, the major agricultural characteristics and grain traits of \"S-21-3-8\" were similar to those of a donor cultivar, \"Ilpum\". \"S-21-3-8\" showed significantly lower (10.6%) amylose than those (17.7%) of \"Ilpum\" in brown rice, while the protein levels were similar to those of the donor plant. The grain hardness of \"S-21-3-8\" (1.67 kgf/mm2) was lower than that of \"Ilpum\" (1.97 kgf/mm2), resulting in a high flour-milling percentage. The loosely packed starch granules of \"S-21-3-8\" in the opaque endosperm were demonstrated by SEM analysis of cross-sectioned rice grains. The opaque endosperm mutants that were of somaclonal variations in the tissue culture will lead to improved eating quality and processing properties of rice.
Factors Affecting Verbal Agitation in Dementia Patients Living in Nursing Homes, South Korea  [PDF]
Eun Kyung Kim, Heeok Park
Open Journal of Nursing (OJN) , 2018, DOI: 10.4236/ojn.2018.86028
Abstract:
The purpose of this study using secondary data analysis was to identify factors affecting verbal agitation in patients with dementia staying at nursing home. This study is a secondary analysis of an existing original quantitative data set (n = 193). A total of 166 subjects’ data were included in this current study after 27 subjects’ data were excluded from the original data because they did not appear verbal agitation. Multiple regression analyses identified hallucination (β = 0.27), total number of physiologic discomforts (β = 0.19) and pain (β = 0.17) as significant predictors of verbal agitation and these factors explained 27.8% of the variance in the model. The findings of this study showed that hallucination, total number of physiologic discomforts and pain with dementia need to be considered when intervention programs to control verbal agitation in patients with dementia were developed.
Trapa japonica Flerov Extract Attenuates Lipid Accumulation through Downregulation of Adipogenic Transcription Factors in 3T3-L1 Cells  [PDF]
Mi Jin Kim, Kyung Ran Im, Kyung-Sup Yoon
American Journal of Molecular Biology (AJMB) , 2015, DOI: 10.4236/ajmb.2015.52004
Abstract: Obesity is a major human health problem associated with various diseases, including cardiac injury and type 2 diabetes. Trapa japonica Flerov (TJF) has been used in traditional oriental medicine to treat diabetes. In this study, we evaluated the inhibitory effect of and the mechanism underlying the effect of TJF extract on adipogenesis in 3T3-L1 cells. The effects of TJF extract on cell viability were analyzed using a 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay, and the anti-adipogenic effect was measured by oil red O staining. The expression of peroxisomal proliferator activated receptor (PPAR)γ, CCAAT/enhancer-binding protein-α (C/EBP)α, adenosine monophosphate-activated protein kinase (AMPK), acetyl-CoA carboxylase (ACC), adiponectin, and fatty acid binding protein (FABP)4 involved in adipogenesis was determined by western blot analysis. TJF extract effectively inhibited lipid accumulation and the expression of PPARγ and C/EBPα in 3T3-L1 cells. TJF also increased the phosphorylation of AMPK and ACC, and decreased the expression of adiponectin and FABP4. These results indicate that TJF extract exerts its anti-obesity effect through the downregulation of adipogenic transcription factors and adipogenic marker genes.
Analysis of Genetic and Biogeography Diversity of Korean Indigenous Wild Rocambole (Allium monanthum Max)  [PDF]
Gihwan Yi, Kyung-Min Kim
American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.45130
Abstract:

This study was conducted to obtain baseline data describing Allium monanthum Max. for breeding an elite cultivar. A. monanthum has recently become popular vegetable in Korea owing to its unique flavors and nutraceutical effects. The agronomic traits of 271 accessions of A. monanthum collected throughout Korea were evaluated in this study. Leaf width showed the greatest variation (0.1 to 25 mm) among traits evaluated, followed by leaf sheath length and number of cormlets. The average leaf sheath length and diameter, which are commonly used to evaluate quality in the market, were 1.29 cm and 0.3 cm. Some superior accessions had a leaf sheath length of >10 cm and diameter of >1.1 cm. The average weight of the cormlets ranged from 1 to 2 g; however, one accession weighed more than 4 g. The genetic diversity of A. monanthum calculated based on morphology and molecular distance was greater in Jeolla and Gyeoungsang provinces than Gyeonggi and Chungcheong provinces. Finally, seven elite accessions of A. monanthum were selected owing to their potential usefulness in future breeding projects.

Interpretable Housing for Freedom of the Body: The Next Generation of Flexible Homes  [PDF]
Kyung Wook Seo, Chang Sung Kim
Journal of Building Construction and Planning Research (JBCPR) , 2013, DOI: 10.4236/jbcpr.2013.13011
Abstract: If we have gone through the first generation of housing design that pursued functional optimization, ergonomics, and circulation efficiency during the last century, now we are living in the second generation where more advanced goals, such as universal design, ubiquitous design, sustainable design, and environment-friendly design, are emphasized. Although this second generation of design focuses upon the wellness of humans in accordance with environment, it still has the attitude that a more precisely designed home can guarantee a better life. What lacks in this approach is the freedom of the body; it needs to make its own choice as to how to use a space. Thus, it is suggested in this paper that what is important in designing a home is to provide alternatives in daily lives so as to make a full exploration of a given space. These alternatives can be made by offering residents an interpretable space where they can figure out space usages and routs in a constantly changing context. Two spatial devices are discussed in depths as a way to realize this interpretable house: room-to-room enfilade and ring spatial structure. By investigating some existing house plans, it is illustrated how they can guarantee the freedom of the body, and thus alternatives for the flexible domestic life.
The Architectural Expression of Space and Form Created by the Light in the Works of Alvaro Siza  [PDF]
Chang Sung Kim, Kyung Wook Seo
Journal of Building Construction and Planning Research (JBCPR) , 2014, DOI: 10.4236/jbcpr.2014.22011
Abstract: The light is an important element which helps people perceive objects. Therefore, it is important for architects to make the light and space be in harmony with each other. In this study, we analyzed the works of Alvaro Siza with a view to understand the conceptual value of the light expressed in his works and his principles in controlling it. According to the results of the study, the Siza’s architecture is not a mere theoretical one trapped inside formality, but is a sensual and experiential one based on the locality. He was willing to use void spaces to invite the light in free-flowing plans, in order to invigorate and extend architectural spatiality to create deeper visual effect. In addition, the refined light in his works helped visitors experience the continuous forms and spaces by their own movements, while using the changes of the light to stimulate the interest of visitors and highlight the sequence of spaces.
Effective Procedure for Development of EST-SSR Markers Using cDNA Library  [PDF]
Kyung A Kim, Hee-Cheon Park, Jae-Keun Sohn, Kyung-Min Kim
American Journal of Plant Sciences (AJPS) , 2012, DOI: 10.4236/ajps.2012.39159
Abstract: The present study was conducted to develop EST-SSR markers using the cDNA library from rice plant. Total RNA extracted from the leaves of brown plant hopper resistance gene originated from a rice cultivar “Cheongcheong” and sensitive rice cultivar “Nakdong” were used to synthesize a cDNA library. As a result of analyzing the cDNA library, the 17 EST-SSR primer sets were developed. This study enables to provide effective marker assisted selection (MAS) methods on the selection of white-backed planthopper resistance gene originated from a rice plant more simply, quickly and precisely. Furthermore, using this marker’s advantage of deriving from cDNA, it is possible to identify the white-backed planthopper resistance gene. In addition, this study introduces a technique for construction of a cDNA library safely without using radioactivity.
