  • The purpose of the study is to come up with counter plans to the spatial change caused by an aging society. To achieve the purpose of this study, research methods are conducted in the literature survey and the census data are compared. This study focuses on an aging society, the current status of space and related problems, based on political economic spatial concepts, and then presents five countermeasures as follows. First, the planning considering the aging populations. Second, increase in total fertility rate and increase population absorption. Third, increased economic vitality of the elderly due to increased participation in the production of senior citizens. Forth, establishment and implementation of regional development plan for the elderly. Fifth, needs to transform the spatial policies of the aged to prepare a large gap in space. The result of this paper proposes the need to change the living space policies and planning to avoid mismatching between them, reducing the aging speed simultaneously. The study is expected to contribute to the establishment of a space plan for areas where the aging population is rapidly increasing.

  • In order to validate the objective efficacy of CBPT on anti-asthma and to develop effective therapeutics for asthma treatments, immunological modulatory mechanism was studied using animal model using OVA-Alum. The results are listed below. When treated with CBPT, survival rate of hFCs at 250 ug/ml was above 90%. AST and ALT, indicators of liver function measurements were in the normal range. Compared to the control group, CBPT treated group showed significant reduction in liver weights at both 400 and 200 mg/kg, and significant decrease of total liver cells at 400 mg/kg. Significant increase in CD4+ and CD8+ cells in DLN was observed in the CBPT treated group. Slight increase in CD3+, CD4+/CD25+ cells were also observed. On the other hand, CBPT significantly reduced the CD3+/CD69+ cell numbers at both concentrations. Slight decrease of CD19+ cells was also observed. CBPT significantly reduced the CD3e+/CD69+, CCR3+ and CD11b+/Gr-1+ cells in lung tissues at both doses. However, significant decrease of CD3e+ and B220+/IgE+ cells was only observed at 400 mg/kg dosed group. The results above strongly suggest the anti-asthmatic effect of CBPT through immunological modulation. By using various concentrations of CBPT, broader clinical applications of CBPT on anti-asthmatic treatment can be developed. The EBM database should provide valuable information in the development of drugs for asthma treatments.

  • The overall consumption of meat is increasing as the level of national income increases. The end weight is a trait closely associated with dressed meat. Genome-wide association study (GWAS) is an effective method of analyzing genetic variation and gene identification associated with a number of natural alternative traits because it can detect variations. So this paper did a GWAS analysis to identity the location on the genome related to the end weight in purebred landrace pigs and to explore the relevant candidate gene. This study identified a significant single nucleotide poly morphism (SNP) marker in chromosome 6 (ASGA0029422, $p=1.22{\times}10^{-6}$). Adhesion G protein-coupled receptor L2 (ADGRL2) was found to be the candidate gene at the identified SNP marker location. ADGRL2 genes have been found to be associated with cell development in relation to the external and internal environment of a cell. In addition, genotype and statistical analyses were done on nine variations on the exon of ADGRL2. The results show that the SNP marker (ASGA0029422, $p=1.32{\times}10^{-6}$) was significant, but the significance of the nine variations on the ADGRL2 exon was not verified. However, by performing further experiments and functional studies on other SNPs showing possible genetic ADGRL-Exon mutations, objects with high associations of high-end weights can be selected.

  • Computational science is at an early stage and is not yet fully active, and the high-performance computing required in the field of computational science is at present a special subject of parallel and distributed computing in computer science. Additionally, there are too few education courses which teach high-performance computing from basic to advanced levels. In this study, we derive the knowledge units needed to learn high-performance computing, an important research tool in computational science. Using ACM the Computer Science Curricula 2013 (CS2013), we examine the validity and reliability of 89 knowledge units and eleven knowledge units with high validity and reliability, after which nine core knowledge units and two optional knowledge units are proposed. The eleven proposed knowledge units are expected to contribute to the development of the high-performance computing curriculum necessary to teach computational science.

  • Traffic congestions in local cities have been getting worse since 1990s, so many local governments have considered the introduction of an LRT system. So far, there is no city operating the LRT due to social environments, financial reasons, feasibility and so on. But still many cities have examined LRT or started the construction. Until now, more than 30 cities are constructing LRT or planning the introduction of LRT and it becomes 96 routes, approximately 700km. With the support of MLTM, KRRI has developed automatic LRT system with rubber-wheels, K-AGT as a result of "LRT system technology development project" from 1999 to 2005 by investing 50.32 billion wons(the public 37, the private 13.32) and finished running durability test of 100,000km at Kyeong-san test line. Currently, two trains, coupled two cars respectively have running and signaling tested. K-AGT was appointed to supply for an extension line at Busan Subway Line 3(Minam-Anpyeong section) with 17 trains(six-unit car) 102 cars. However, except for Minam-Anpyeong section, other cities such as Uijeongbu, Yongin, Daegu(Line 3) and Kwangmyeong decided to use the foreign systems, not to use the product, a result of national R&D project. This results in a huge waste of foreign currency and it is expected to require much additional cost for maintenance. If local governments use the products of national R&D projects, many national benefits such as reducing imports and protecting home industries could be expected, therefore in this paper, some plans to encourage to use products of national R&D projects were dealt with.

  • This study is based on the results of the $7^{th}$ Korea Human Size Survey (Size Korea). The standard body shapes of Korean women between 25 and 34 years old were analyzed and used to develop a prototype princess line for wedding dresses. or this purpose I conducted a literature review and a survey of the actual situation of domestic ligaments. In order to select suitable ligaments for the standard body type of 25~34 year-old Korean women, I collected the most representative ligaments from around the world: Stock man from France, Superior from the USA, KIIYA from Japan, and Pig and Nonno from Korea. They were then compared and analyzed. In the form of a formal wedding dress, a prototype princess line was developed by a draping technique in order to finely implement the human body fitting. To develop the prototype of the princess line, I made test garments with muslin. 25 to 34 years old Korean female standard body type Three human subjects close to the average measurement value were selected as subjects. An exterior appearance evaluation questionnaire was created with 28 questions focusing on the main parts of the prototype princess line. The clothes were evaluated three times. In this study, aesthetic and functional elements were considered for the development of princess line prototypes for wedding dresses. In addition, the amount of spare area was given differently. This study is significant in the achievement of a dress line closest that closely matches the human body line of the standard Korean female body type.

  • Lycopene, found in tomatoes and tomato products, has antioxidant, anticancer, and anti-inflammatory effects. High-mobility-group box 1 (HMGB1) mediates the pro-inflammatory responses in several inflammatory diseases. In this study, the potential roles of lycopene in the HMGB1-mediated pro-inflammatory gene expressions in the primary human-umbilical-vein endothelial cells (HUVECs) were investigated. The data showed that HMGB1 upregulated the expressions of monocyte chemotactic protein 1 (MCP-1), interleukin-6 (IL-6), secretory phospholipase A2 (sPLA2)-IIA, and prostaglandin E2 (PGE2). Lycopene pre-incubation for 6 h decreased the HMGB1-mediated induction of MCP-1, IL-6, sPLA2-IIA, and PGE2. Further study revealed that the inhibitory effects of lycopene on the HMGB-1 induced expression of pro-inflammatory genes were mediated by the inhibition of two important inflammatory cytokines: tumor necrosis factor (TNF)-${\alpha}$ and nuclear factor (NF)-${\kappa}B$. These results suggest that HMGB1 upregulated the expression of pro-inflammatory genes and lycopene inhibited HMGB-1-induced pro-inflammatory genes by inhibiting TNF-${\alpha}$ and NF-${\kappa}B$. This finding will serve as an important evidence in the development of a new medicine for the treatment of inflammatory diseases.

  • The amount of spent fuel from nuclear power plants has been increasing. An effective management plan of the spent fuel becomes a critical issue, because the storage capacity of each plant will reach its storage limit in a few years. The volume of high toxic spent fuel can be reduced through a fuel processing. Advanced Fuel Cycle (AFC) system is considered to be one of the options to reduce the toxicity and volume of the spent fuel. It is necessary to set up a test facility to demonstrate the feasibility of the process at the engineering scale. The objective of the work is a development of the safety evaluation technology for the AFC system. The evaluation technology of the AFC structural integrity and processes were surveyed and reviewed. Key evaluation parameters for the main processes such as electrolytic reduction, electrorefining, and electrowinning were obtained. The survey results may be used for the establishment of the AFC regulatory licensing procedure. The establishment of the licensing criteria minimizes the trials and errors of the AFC facility design. Issues taken from the survey on the regulatory procedure and design safety features for the AFC facility provide a chance to resolve potential issues in advance.
