This study was conducted to compare the growth, inorganic components, and proximate components of Codonopsis lanceolata grown in 10 regions of Korea for selecting superior species and breeding by crossing. Among the all tested lines, the shortest plant height (217.12 cm) was observed from the Ulleungdo region line (No. 4) while the longest (273.9 cm) was observed from Hwasun region line (No. 9). In addition, the lines of central and northern region (No. 1~No. 7) tend to have shorter plant height than those of southern region (No. 8~No. 9) except Jejudo region line (No. 10). Flowering tends to be late towards southern region, and lines in central and northern regions were started flowering about 2 weeks earlier than those in southern regions. However, the heaviest root weight was 13.1 g, found in only Jejudo line (No. 10) whereas there was no significant difference found in the other regions which have a range of 8.3~11.0 g. The inorganic components were varied in each line, however, proportion of macroelements, such as K, Ca, and P, was the largest for every line. Especially for Heongseong region line (No. 2), had larger proportion of macroelements than the others. There was a difference of proximate compositions of Codonopsis lanceolata, except the moisture content, among all regions, however, it was generally shown that the content of crude protein (1.31~3.76%) and crude fiber (2.18~3.12%) was the highest.

The Science and Technology process focuses on a number of areas where science and technology development provides a major opportunity to innovate water resources management. A number of areas have been carefully selected and are described below. Main focus 1: Efficient water management Today’s water management continues to be highly inefficient in many respects, seriously hampering the sustainable management of water resources, delivery of services and the protection of human health and the environment. In the years to come, major efforts will need to be made to improve water efficiency as a means to secure water resources, adapt to climate change, or operate water services systems at lower costs. Sub Focus: Urban water efficiency, Agricultural water efficiency, Industrial water efficiency, Energy efficiency in water and waste water systems Main focus 2: Resource recovery from water and waste-water systems Increasingly, water and waste-water systems are recognized as potential sources of recovering water, energy, nutrients and other materials. At the same time, the re-use of waste water in agricultural, industrial and urban applications is gaining momentum. The development of re-use and recycling within the water and waste-water sectors provides major opportunities for improving environmental performance, creating climate benefits and reducing costs. Sub Focus: Water re-use and recycling technologies, Energy recovery and production from water and waste water cycles, Nutrients recovery from waste water Main focus 3: Water and Natural disasters As the devastating impact of recent natural disasters such as the flood occurred in Thailand in 2011, indicates, mankind is vulnerable to extreme weather events in developing and even in developed countries. Clearly, such extreme events have always been part of our life and may be caused by climate change. This makes water related problems, especially, such as floods and droughts, more difficult to analyze and predict. Climate change is predicted to have a range of serious consequences, some of which will have impact over the longer term, like droughts, while some have immediate and obvious impacts, such as intense rain and flooding. Floods and droughts are major natural disasters involving loss of life and the destruction of property. So, we may need advanced technologies and measures in order to cope with natural disasters. Sub Focus: Climate change : impact assessment and adaptation, Drought analysis and management, Urban floods and damage reduction studies, RS and GIS applications for natural hazards Main focus 4: Smart technology for Water Water management is increasingly influenced by developments in Smart Technology(ST). Better use of this ST in measuring, monitoring and distributing water can lead to a significant contribution in overcoming water management challenges in the 21st century. Bridging the ‘divide’ between the water and ST sectors will be important in the development and (wide-scale) application of new smart technologies in the water sector. Sub Focus: Urban and Irrigation water management and ST, Integrated and intelligent river basin water management and ST, Design and implementation of smart water grid, Water resources management and Big Data Main focus 5: Understanding and managing ecosystem services for water Ecosystems provide valuable services underpinning water security and the sustainable management of water resources. In recent years, major advances have been made in understanding the role of ecosystems in, for example, reducing floods, recharging aquifers, or protecting and improving water quality. Sub Focus: The science and technology of natural and green infrastructure management, The economic valuation of ecosystem services for water, The payment for ecosystem services for water quality and delivery

Manganese () is a trace element that is essential for normal physiology, and is predominantly obtained from food. Several lines of evidence, however, demonstrated that overexposure to exerts serious neurotoxicity, immunotoxicity and developmental toxicity, particularly in male. The present study aimed to evaluate the effect of 0, 1.0, 3.3, and 10 mg/kg/day doses of on the reproductive organs in the immature female rats. Rats (PND 22; S.D. strain) were exposed to () dissolved in drinking water for 2 weeks. The animals were sacrificed on PND 35, then the tissues were immediately removed and weighed. Histological studies were performed using the uteri tissue samples. Serum LH and FSH levels were measured with the specific ELISA kits. Body weights of the experimental group animals were not significantly different from those of control group animals. However, ovarian tissue weights in 1 mg and 3.3 mg dose groups were significantly lower than those of control animals (p<0.05 and p<0.01, respectively). Uterine tissue weights of 3.3 mg dose groups were significantly lower than those of control animals (p<0.01), while the 1 mg dose and 10 mg dose failed to induce any change in uterine weight. Similarly, only 3.3 mg dose could induce the significant decrease in the oviduct weight compared to the control group (p<0.05). Non-reproductive tissues such as adrenal and kidney failed to respond to all doses of exposure. The uterine histology revealed that the exposure could affect the myometrial cell proliferation particularly in 3.3 mg dose and 10mg dose group. Serum FSH levels were significantly decreased in 1mg dose and 10 mg groups (p<0.05 and p<0.01, respectively). In contrast, treatment with 1 mg dose induced a significant increment of serum LH level (p<0.05). The present study demonstrated that exposure is capable of inducing abnormal development of reproductive tissues, at least to some extent, and altered gonadotropin secretions in immature female rats. Combined with the well-defined actions of this metal on GnRH and prolactin secretion, one can suggest the might be a potential environmental mediator which is involved in the female pubertal process.

We examined the morphometric characteristics and fluctuating asymmetry of diploid and triploid marine medaka, Oryzias dancena. We used morphometric parameters the truss and classical dimensions. Significant differences in all the classical and truss dimensions of the diploid and triploid fish. All the dimensions of the triploid fish were greater than those of the diploid fish. The triploid marine medaka shows sexual dimorphism in these characters, and the sexual dimorphism of the triploid marine medaka is similar to that of the diploid marine medaka. Thus, the growth of triploid marine medaka is faster than that of the diploid fish, and it displays clear sexual dimorphism, with male fish having longer dorsal and anal fins than female fish. we examined fluctuating asymmetry of eye diameter, maxilla length, operculum length, number of pectoral fin ray and number of pelvic fin ray. In all experimental groups, Eye diameter and maxilla length showed no significant difference between left side and right side (P>0.05). Trends of operculum length in triploid male group and pectoral fin ray's number in diploid male group showed similar trend with trends of operculum length in triploid female group and pectoral fin ray’s number in diploid female group. However, trends of operculum length in diploid male group and pectoral fin ray's number in triploid male group showed opposite trend with trends of operculum length in diploid female group and pectoral fin ray’s number in triploid female group. Trend of pelvic fin ray's number in all groups showed similar trend with trend of pectoral fin ray’s number in all groups.

During the last decade, considerable progress has been made to understand the molecular mechanisms of M. grisea infection in rice plants and 10 rice blast R genes have been identified and characterized via map-based cloning methods. In case of rice germplasm, the genetic backgrounds of each germplasm accessions are not uniform and the evaluation for pathogenicity is difficult. To solve these problems, we applied the single resistance gene markers to rice germplasm accessions. A molecular survey was conducted to identify the presence of major blast resistance (R) gene in 363 accessions of Korea landrace rice germplasm. The results revealed that the resistance gene Pik-p (100%), Pib (98%), Pi-d(t)2 (98%) and Piz (76%) were widely observed in tested rice germplasm, but Pita-2, Pik and Pi39 gene were identified in less than 10 accessions. Most of landrace contain the four or five different resistant genes, but these results was not consist of field nursery screening. 13 accessions were shown the blast resistance in field nursery screening and Pik-p, Pib, Pi-d(t)2 and Piz genes were observed in these accessions. The evaluation results of blast resistance genes in rice germplasm will help in breeding of multi disease resistant varieties.

Protein related parameters of pan bread and white salted noodles prepared from 26 Korean wheat cultivars and 6 commercial and imported wheat flours were evaluated to elucidate the relationship between rheological properties and end-use characteristics and to determine the effects of Glu-1 and Glu-3 alleles on those characteristics in Korean wheat cultivars. SDS-sedimentation volume based on protein weight was positively correlated with mixograph parameters and maximum height of dough and also positively correlated with bread loaf volume, crumb firmness and springiness of cooked noodles. Within Glu-1 loci, 1 or 2* subunit and 5 + 10 subunits showed longer mixingtime, higher maximum height of dough, and larger loaf volume than null allele, 2.2 + 12, and 2 + 12 subunits. Cultivars with 13 + 16 subunits at Glu-B1 locus showed higher protein content and optimum water absorption of mixograph than cultivars with 7 + 8 subunits. At Glu-3 loci, Glu-A3d showed longer mixing time than Glu-A3e, and Glu-B3d and Glu-B3h had stronger mixing properties than Glu-B3i. Glu-B3h had higher loaf volume and hardness of cooked noodles than Glu-B3d. Glu-D3a had lower protein content than Glu-D3c, and Glu-D3b showed stronger mixing properties than Glu-D3a. Glu-D3c showed lower hardness of cooked noodles than others.
