  • In this study, the separation of toxic dioxin 2,3,7,8-congeners by DB-5MS and SP-2331 GC columns which are widely used in HRGC/HRMS analysis was examined. Through the dioxin analysis of column performance check standard solution and fly ash sample, the isomer specific separation of 2,3,7,8-substituted dioxins from tetra to hexa-isomers on DB-5MS and SP-2331 columns were studied. The effect of I-TEQ value by these columns was also studied. The total concentrations of toxic dioxins for the column performance check standard solution were 508.4 ng/mL analyzed by DB-5MS and 515.8 ng/mL analyzed by SP-2331, respectively. The I-TEQ value obtained by both columns was shown to be almost equivalent for the column performance check standard solution and fly ash sample.

  • As a project delivery method, Design-Build (DB) has provided owner, architect, and contractor groups with a process of early design and rapid construction for the past three decades. Although there are many benefits to using standard DB, dissatisfaction has arisen due to limitations to innovate, limited owner involvement during design, and often lengthy procurement. Progressive Design-Build (PDB) has become an appealing alternative providing benefits not seen with standard DB. This paper investigates how PDB impacts a project and how it compares against standard DB; it also presents a proposed framework for evaluating the owner's responsibility and assessment of a project, which we named the "Four Pillars of Project Success". The four pillars are defined with respect to an owner's responsibility and assessment of a project, including project predictability, project risk, project schedule, and project cost. We conducted a literature review, examined several public project case studies, analyzed PDB project information collected by the Design-Build Institute of America (DBIA), and held stakeholder interviews with owners, contractors, and architects who have used both PDB and standard DB. This paper offers insight into PDB's structure and outcomes so an owner group can make an informed decision when considering PDB as their next construction contracting method.

  • The purpose of this study was to investigate the gene profiles that were up- or down-regulated in the livers of high-fat diet-induced obese mice and $db_-/db_-$ mice with deficient leptin receptor. C57/BL6 normal mice and $db_-/db_-$ mice, respectively, were divided into two groups and fed a standard or high-fat diet for four weeks. Liver weight was unchanged in the normal mice but the high-fat diet led to a 10% weight increase in the $db_-/db_-$mice. Adipose tissue mass increased by about 88% in the normal mice that were fed a high-fat diet and by about 17% in the $db_-/db_-$mice on the high-fat diet. In terms of serum lipids, total cholesterol significantly increased in mice on the high-fat diet. Microarray analysis was carried out using total RNA isolated from the livers of standard or high-fat diet-fed mice of the normal and $db_-/db_-$ strains. The change of gene expression was confirmed by RT-PCR. About 1.6% and 6.8% of total genes, respectively, showed different expression patterns in the normal mice fed the high-fat diet and $db_-/db_-$ mice. As a result of microarray, many genes involved in metabolism and signal pathways were shown to have different expression patterns. Expression of Mgst3 gene increased in the livers of normal and $db_-/db_-$ mice that were fed a high-fat diet. Wnt7b and Ptk9l were down-regulated in the livers of the normal mice and $db_-/db_-$ mice that were fed a high-fat diet. In conclusion, a high-fat diet induced obesity and affected gene expression involved in metabolism and signal pathway.

  • The purpose of this paper is to report the whole process of developing Korean Standard Speech Database (KSS DB). This project is supported by SPO (Supreme Prosecutors' Office) research grant for three years from 2014 to 2016. KSS DB is designed to provide speech data for acoustic-phonetic and phonological studies and speaker recognition system. For the samples to represent the spoken Korean, sociolinguistic factors, such as region (9 regional dialects), age (5 age groups over 20) and gender (male and female) were considered. The goal of the project is to collect over 3,000 male and female speakers of nine regional dialects and five age groups employing direct and indirect methods. Speech samples of 3,191 speakers (2,829 speakers and 362 speakers using direct and indirect methods, respectively) are collected and databased. KSS DB designs to collect read and spontaneous speech samples from each speaker carrying out 5 speech tasks: three (pseudo-)spontaneous speech tasks (producing prolonged simple vowels, 28 blanked sentences and spontaneous talk) and two read speech tasks (reading 55 phonetically and phonologically rich sentences and reading three short passages). KSS DB includes a 16-bit, 44.1kHz speech waveform file and a orthographic file for each speech task.

  • Antidiabetic activity and mechanism of Supungsungihyan(SPSGH) were examined in db/db mice, which is a spontaneously hyperglycemic, hyperinsulinemic and obese animal model. SPSGH and acarbose were administered orally for 4 weeks. Fasting and non-fasting serum glucose, glycated hemoglobin and trig-lyceride of SPSGH treated group were all reduced when compared with those of db/db control group. At 12th week after birth, SPSGH increased an insulin secretion although statistic significance was not seen. Total activities of sucrose, maltase and lactase in SPSGH treated group were not significantly different from those in db/db control. On the other hand, sucrase and maltase activities in acarbose treated groups were increased. Effect of SPSGH on mRNA expression of glucose transporter(GLUT-4) was also examined by RT-PCR and in vitro transcription with co-amplification of rat $\beta$-actin gene as an internal standard. Muscular GLUT-4 mRNA expression in SPSGH treated group was increased significantly. These results may suggest that SPSGH lowered blood glucose ascribing to upregulation of muscular GLUT-4 mRNA expression.

  • Due to recent climate change, lager-scale storm and flood disasters have occurred. To prepare for this, the government is operating the national disaster management information system(NDMS), it is insufficient that unification and standardization of disaster site information data. In this study, to establish a disaster information display system, spatial DB was stored, quality standards were presented and the quality of spatial information currently provided was evaluated. As a result of evaluation, spatial information is established as different standard for each institution. So it is difficult to integrate and use. It considered that prepare a common standard to redeem this difference.

  • Antidiabetic activity and mechanism of Sangbackpitang (SBPT) was examined in db/db mice, which is a spontaneously hyperglycemic, hyperinsulinemic and obese animal model. SBPT and acarbose were administered orally for 4 weeks. Fasting and non-fasting serum glucose, glycated hemoglobin and triglyceride were all reduced when compared between db/db control group and SBPT treated group. At 12th week after birth, SBPT increased an insulin secretion although statistic significance was not seen. Total activities of sucrase, maltase and lactase in SBPT treated group were all decreased when compared to db/db control. On the other hand, sucrase and maltase activities in acarbose treated groups were increased. Effect of SBPT on mRNA expression of glucose transporter(GLUT-4) was also examined. Quantitation of glucose transporter was performed by RT-PCR and in vitro transcription with co-amplification of rat-action gene as an internal standard. Muscular GLUT-4 mRNA expression in SBPT treated group was increased significantly. These results may suggest that SBPT lowered blood glucose ascribing to inhibition of glycosidase-catalyzed reaction and upregulation of muscular GLUT-4 mRNA expression.

  • Forest type map is a main forest thematic map which shows forest type, age class, diameter class and density. This map has been used as a base data in various fields such as forest policy decision-making, land suitability assessment and eco map production etc. But the existing map had many kinds of errors and no metadata because there was no standard for digital map production. On this study, we developed standard for digital forest type map production consisting of 33 unit processes including DB schema design, mapping process, quality control and metadata input process. Based on this standard, country-wide digital forest type map can be produced with consistent quality and standard metadata.
