Recently expanding market for largely scale construction projects, cost management of construction project have been increasingly recognized as an important factor responsible for the project success. But public organizations have been continuously operating the same methods as before in cost estimating, so it raise an issue of reliability for estimated cost. Therefore, this study present a highly reliable model that makes preliminary estimates based quantity data in early design stage. it enables engineers to efficiently manage total cost of project as well as partial cost estimating. This study develop a model of database that is created with historical data conducted by government offices. The model proposed can estirnate a cost for RC Structure in schematic design stage, and it is applied to CBR+GA logics to explore best similar cases. In case of estimating methods used to previous research, it is based on actual cost data. Due to the cost estimating compensated by inflation rate vary in market economic conditions, it will follow as an inevitable consequence of reliability problem. It needs to find better way to ensure accuracy through quantity database. Also, This study has been conducted in attempts to verify the reliability of preliminary estirnation. It is checked for the feasibility of presented model with P-National Tax Service Project aside from the database.

A prediction of construction cost in preparation for construction document is calculated in compliance with the unit cost in Public construction of korea. This eventually means that the reasonable construction cost of a building can't be determined before construction document phase cost of construction is settled and that the cost of construction is calculated inefficiently because of connection failing between cost management of detailed estimation and information. To improve those problems, therefore, Cost estimating model of structural building elements with approximate quantity survey method is suggested in this research. The model predict the amount of materials and the cost of construction on the basis of historical similar cases. In the direction of data analysis of this research, ratio statistics value is put to practical use to fit into the peculiarities of approximate estimate of each work trade on the basis of actual data amount of materials of historical cases. In addition, the construction phase is connected through the result of a approximate estimate sorted by elements, details work trade.

Background: The light emitting plasma (LEP) has recently attracted attention as a novel artificial light source for plant growth and functional component enhancement. We investigated the effects of LEP on whitening and antioxidant activities of the plant parts of perilla. Methods and Results: Previously germianted seeds of perilla were cultivated under different light conditions (fluoresce lamp, LED red, blue, white, green, and LEP) in a culture room for 2 months. Parts of perilla were harvested and extracted in 70% EtOH. The extracts were used to detect total phenolic contents, total flavonoid contents, 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2’-azino-bis- 3-ethylbenzothiazoline-6-sulfonic acid (ABTS), reducing power and tyrosinase inhibition activity as indicators of biological activity. Biological activity was highest in seedlings grown under LEP. The total phenolic content was highest in the stems and the total flavonoid content was highest in the roots of perilla exposed to LEP. The DPPH and ABTS radical activity in all the parts of perilla exposed to LEP were higher by approximately three-fold compared to that in the control (fluoresce lamp). The reducing power values of perilla significantly increased after treatment with LEP. In addition, all the extract of perilla plants exposed to LEP promoted the tyrosinase inhibitory activity. These results suggest that LEP can be an important artificial light source for enhancement of biological activity. Conclusions: LEP could promote whitening and antioxidant activity of perilla.

Background: Sorghum is a major cereal food crop used in many parts of the world. It has been grown on a subsistence level by farmers, under various conditions of environmental stresses in the semi-arid tropics of Africa and Asia. This plant has received significant attention because of its ability to reduce cholesterol in the blood, and its anti-dementia, antioxidant, and antimicrobial properties. It is possible to develop a functional and commercially viable sorghum variety by using superior cultivars of sorghum. The objective of this study was to build a database of superior sorghum accession.Methods and Results: We used 250 sorghum accessions collected from different geographical bioregions in Korea. We determined various agronomic characters including germination rate and ear length of these accessions. To determine the antioxidant capacity, we measured the 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity, 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid)-diammonium salt radical scavenging activity, total phenolic contents, and total flavonoid contents. Accession 189 showed higher germination (> 80%) than the other accessions. Higher 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity was observed in 11-SB-078 (RC50; 1.89 ± 2.88 μg/ml), and higher 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid)-diammonium salt radical scavenging activity was recorded in 11-SB-116 (RC50; 35.48 ± 2.42 μg/ml) than in the other accessions. The ear length ranged from 15 ㎝ to 48 ㎝, the total phenolic contents ranged from 3 ㎎• GAE/g to 77 ㎎• GAE/g, and total flavonoid contents ranged from 0.09 ㎎• QE/g to 1.07 ㎎• QE/g.Conclusions: Among 250 sorghum accessions, we selected 10 with both superior agronomic characters and highly functional food quality.

Other phytochemical such as non-saponins of fatty acid has been revealed its bioactive activity including anti-oxidation, whitening, anti-cancer. Supercritical extraction (SE) process mainly refer to the extraction with CO2, is usually from a solid matrix, is a sample preparation step for analytical purposes. SE produce no residual solvent and possess high stability of the extract component, which is advantageous for fatty acid analysis. Methods and Results : Fermented ginseng cultured roots used in the experiment were used for fermentation using Pediococcus pentosaceus. SE performed at different temperature, pressure and extraction time using non-fermented and fermented ginseng roots. Further we fractionated from fermented ginseng using Methanol, Hexane, Ethanol, Ethyl acetate and Butanol. We compared fatty acids contents ginseng extractions by GC analysis. Methyl linoleate contents was 44% of fatty acids supercritical extraction contained. The contents of Methyl linoleate was the most dominant component among 37 types of fatty acids by SE and other extractions solvent. Total fatty acids contents obtained by SE process from fermented ginseng (1325.61ppm) was twice than from non-fermented ginseng (618.47ppm). Conclusion : Fatty acids contents by SE was increased at high pressure. The best condition for fatty acids contents extraction was 60℃, 350bar and 3h.

Background : Perilla frutescens L. is valuable as a medicinal plant as well as a natural medicine and functional food. Limonene perilla collected from various places showed 60% limonene compounds. However biological activity of these accession has not been reported before. Therefore, this study was conducted to investigate the biological activity of limonene perilla. Methods and Results : Fractional solvent extracts were obtained by using organic solvents such as n-hexane, chloroform, ethyl acetate, n-BuOH, and aqueous solvent from different parts of limonene perilla extracted initially in 70% EtOH. We investigated the effects of limonene perilla on total phenol and flavonoid contents, FRAP (Ferric Reducing Antioxidant Power), total saponin contents and tyrosinase inhibition activity. Leaves of limonene perilla produced the highest total phenolic contents (29.88 mg·CAE/g), flavonoid (8.39 mg·QE/g) and saponin contents (47.77 mg·GIE/g) than stems and roots of limonene perilla. FRAP of leaves was 823.00±3.58 μM·FeSO4·E/mg. Tyrosinase inhibition activity rate was 40.31% in 70% ethanol extracts from leaves of limonene perilla. Conclusion : This results suggest that leaf of limonene perilla fractions has significant antioxidant activity. Also, limonene perilla could be used as a functional biomaterial in developing cosmetics and functional foods.

Background : Temperature is major factor for growth plant. Recently, because of global warming, abnormal temperature included drought, deluge, sudden temperature change and heavy snow damaged crops in the world. In Korea, crops have been sensitive to low temperature on early growth stage, e.g. fruit tree and ginseng, were damaged owing to sudden heavy snow and cold on Spring. Therefore, recently interest in cold resistance crops were increased in demand rapidly. This study was performed to establish transgenic Nicotiana benthamiana by transforming cold resistant gene related to cold tolerance S-adenosylmethionine synthetase (SAMS) isolated from Miscanthus sinensis. Methods and Results : Total RNA was extracted from leaves of M. sinensis using Trizol assay and isolated MsSAMS. Isolated MsSAMS was insert into SacⅠ- XbaⅠ sites of pMBP1 vector. The vector was transformed to Agrobacterium tumefaciens strain LBA4404 by DH5α. A. tumefaciens with binary plasmid were selected at YEP medium supplemented with kanamycin. Cut leaves of tobacco were co-cultured with selected A. tumefaciens. Co-cultured leaves was grown on regeneration medium for a month at dark condition, and transferred to at light condition. Regeneration shoot from callus were excised and transferred to root-induction medium. Approximately, 58% of leaves explant produced callus. Nearly, 30% of callus had shoot and approximately, 94% of shoots were rooted in root-induction medium. Conclusion : We established an efficient transformation system of N. benthamiana transformed by using MsSAMS gene related to cold tolerance isolated from M. sinensis. We may use the produced transgenic plants to prevent damages carried by cold.

Background : Perilla frutescens L. is a bisexual, annual plant belonging to the Labiatae. Dormancy period of Perilla seed usually ranged from 85-200 days. The germination enhancing effects in a reduced seed vigor during the GA3 treatment has been reported. Objectives of the present study was to evaluate the effect of GA3 on germination rate and the expression of germination-related genes expression by using perilla seeds. Methods and Results : Three different cultivars (Saeyeopsil, Okdong) and accession (line 141) of perilla were used in the experiment and treated with GA3 at different concentration (50, 100, 300, 500 μM) for one day at dark condition. Germination test for perilla seed was carried out by using 100 perilla seeds treated with GA3 at 25℃. Rate of germination were evaluated after 10 days and the experiments were repeated three times in similar condition. Samples were collected from each cultivar and accessions for RNA extraction. After cDNA synthesis quantification, templates were subjected to RT-PCR using actin primers. EST blast performed for sequencing the RT-PCR products. Conclusion : Result showed that 100μM GA3 treated seeds of three perilla cultivars and accessions showed the highest germination rate. However, concentration of GA3 over 100 μM and lower than 100 μM resulted into reduced germination rate. Furthermore, expression of germination-related genes from 100 μM treated GA3 was higher compared to untreated sample by using 100 μM GA3 treated sample by using pC12, pJ14 primers.

Background: This study was conducted to investigate the effects of germanium treatment on the growth and organic germanium production in the roots of Oplopanax elatus plantlets. Methods and Results: O. elatus plantlets were cultured in Murashige and Skoog (MS) medium with different concentrations of germanium dioxide (GeO2) to analyze optimum growth conditions. Exogenous treatment of 10 ㎎/ℓ GeO2 promoted growth and an increase in the contents of chlorophyll a, b and carotenoid in O. elatus. The germanium accumulation and production in roots of O. elatus plantlets treated with organic germanium reached the highest levels. The growth of the aerial and underground portion of O. elatus with organic germanium was greater than that of the control. The accumulation and production of organic germanium reached the highest level (40.89 ㎍/plantlet) with the treatment of 50 ㎎/ℓ GeO2. Antioxidant activity measured by DPPH and ABTS assays also increased with the germanium treatment and improved the DPPH and ABTS radical activity by 200% compared with that in the control. In addition, the total phenol and flavonoid contents of the plantlets with a treatment of 50 ㎎/ℓ GeO2 were higher than in the control. Conclusions: Taken together, the growth of O. elatus was increased with the treatment of 50 ㎎/ℓ GeO2 germanium and the biological references improved, with increased antioxidant activity and organic germanium production.
