This article analyzes biographies of women participants in Miryang struggle against 765㎸ transmission tower and finds that the experience of state violence under the ideological conflicts works the biographical context of participation in environment movement. The cases analyzed in this article disclose the family member's experience of state violence and their trauma through the participation in social movement. And they legitimize their family member's life, heal their trauma, and live a new life by the social movement participation. But the power of healing trauma comes from solidarity and support in social movement. Findings of this article imply that experiences of state violence have influence on the formation and development of various Korean social movements and we need more solidarity and democracy for healing the trauma occurred by state violence and concealed in individual memory. Findings of this article also suggest the importance of biography documents. Biography documents can contribute to widen and to deepen understandings on the social interaction and social history, because they are the document about people's experience who are excluded from the official history and character culture. Moreover biography documents can compensate the official documents, because they can offer the context to the social actions in the official documents. More accumulations and analyses on biographies can serve to widen and to deepen understanding and explanation of Korean society having multilayered exclusion in the process of the compressed modernization and the history of national division.

This study was conducted to derive a society and education system model that will improve the happiness and sustainability of human society. An ideological model for making human society a happy society was derived, and a society and education system structure and operation model based on this was presented. A fair society, a justice society, a mutually considerate society, and a society where individuals are happy are the conditions for a sustainable society. After analyzing the current situation of freedom and equality pursued by capitalism and democracy, which are currently adopted by most societies, an improvement model was derived from the perspective of a sustainable society. The cost of freedom and equality were analyzed and a new alternative system was discussed. The social solidarity and class mobility issues were discussed together and servicism was derived as an alternative solution. It is a system in which two opposing opponents of individual freedom and social norms form a symmetrical balance, and material and spiritual values are balanced. Servicism is a dynamic balance model. That is, the dimensions of time and space are involved. It is a model that maintains a thorough balance through a dialectical process as time and space change, and one value can dominate the other at a specific time or space. The service-oriented society and education system is a system that simultaneously pursues the goals of individual happiness and sustainable development of the social community.

This study was conducted to derive a model of a sustainable politics and administration system that will enhance human happiness. A new long-term sustainable development model has been established based on the experience of the politics and administration system over the past thousands of years. Currently, the democratic political system and the bureaucratic administrative system dominate, but they are facing many problems. In this study, we analyzed the politics and administration system experienced by human society, and derived a model of a politics and administration system that is ideal for the present and future societies and is sustainable in the long term. The necessary condition should be a model that can solve the problems of the current politics and administration system. It must be a model that is faithful to the characteristics and essence of modern society. And as a sufficient condition to ensure long-term sustainability, it must be based on the common principles of human society. After analyzing the problems of the current system and analyzing the conditions required for the new system, the axioms that are the basis of the politics and administration system were presented. Based on the axioms, the structure and operation model of a new politics and administration system were derived. The derived model was named as a servicism politics and administration system. It is a dynamic model in which two opposing opponents recognize each other's contradictions and balance them dialectically in the space-time dimension.

This study was conducted to derive a Korean model that can permanently maintain and develop Korea. After analyzing Korean society, especially modern Korea, which was the foundation of the founding of the Republic of Korea, a Korean model that can lead Korean society as a sustainable society in human society was derived. The situation of Korea and Koreans was analyzed from a fundamental level. We analyzed the root causes of deepening division and conflict and vague concepts of freedom and justice, and presented a Korean model of the Republic of Korea based on the founding ideology and constitutional spirit of the Republic of Korea to solve these problems. The necessary conditions for being a Korean were derived from the founding ideology and constitutional spirit of the Republic of Korea, the indigenous ideology of Korea, and the fashion and lifestyle of Koreans, derived. In addition, basic axioms for the Korean model were presented, and the structure of the Korean model was designed based on this. The Korean model is presented so that Korean society can lead the human society and be happy for a long time. Reflecting the results of in-depth analysis of the ideological foundations of modern Koreans, a new long-term sustainable structure for Koreans with various ideologies to live well together was proposed. The new Korean model was named the service-oriented Korean model. This is because it is a model centered on thorough checks and balances between all opponents, because it is a multidimensional dynamic Korean model rather than a simple linear one-dimensional Korean model, and because it is a Hwajaengtaeguk model that accurately expresses the identity of Koreans. It was proposed as a model for the sustainable development of Korean society. A follow-up study on specific Korean education programs is needed in the future.

Purpose : Glycogen storage disease type Ia(GSD Ia) is an autosomal recessive disorder caused by the deficiency of glucose-6-phosphatase(G6Pase). The aim of the study was to investigate the spectrum of G6Pase gene mutations and relationship between genotype and clinical findings in Korean patients with GSD Ia. Methods : Genomic DNA was extracted from peripheral leukocytes of 20 patients with GSD Ia. The five exons of G6Pase gene were amplified and PCR products were directly sequenced. The frequency of short stature, hypoglycemia, hypercholesterolemia, hyperuricemia, hypercalciuria, nephrocalcinosis and hepatic adenoma was compared between 727G>T homozygotes and 727G>T compound heterozygotes. Results : A total of 5 different mutations were identified. The most common mutation was the 727G>T with an allele frequency of 80%. All patients were either homozygous(12/20) or heterozygous(8/20) for the 727G>T mutation. G122D was found in 3 patients, P178A in 1, G222R in 2, and S339R in 2. There was no difference in the frequency of short stature, hypoglycemia, hypercholesterolemia, hyperuricemia, nephrocalcinosis, and hepatic adenoma between 727G>T homozygotes and heterozygotes. Conclusion : Diagnosis of GSD Ia can be based on clinical and biochemical abnormalities combined with mutation analysis instead of enzymatic diagnosis that requires liver biopsy. Homozygosity for the 727G>T does not seem to alter the disease phenotype as compared with the heterozygous state.

In online communities, a large number of participants can exchange their opinion using replies without time and space restrictions. While the online space provides quick and free communication, it also easily triggers unnecessary quarrels and conflicts. The network established on the discussion participants is an important cue to analyze the confrontation and predict serious disputes. In this paper, we present a quantitative measure for polarity observed on the discussion network built from reply exchanges in online communities. The proposed method uses the comment exchange information to establish the user interaction network graph, computes its maximum spanning tree, and then performs vertex coloring to assign two colors to each node in order to divide the discussion participants into two subsets. Using the proportion of the comment exchanges across the partitioned user subsets, we compute the polarity measure, and quantify how discussion participants are bipolarized. Using experimental results, we demonstrate the effectiveness of our method for detecting polarization and show participants of a specific discussion subject tend to be divided into two camps when they debate.

We conducted QTL mapping for 6-year growths of open-pollinated half-sib progenies from a selected clone 7-1037 in Pinus taeda. With an AFLP marker analysis on haploid DNA samples from the megagametophytes of the open-pollinated seeds, we constructed 20 framework maps spanning a total of 1,869 cM in total length and 18.5 cM in an average interval length between markers. Composite interval mapping reveals that one QTL explains 5.9% of the total phenotypic variation of height, and three QTLs account for 3.9~5.6% of the variation of diameter at breast height (DBH). There are no correlations between the QTLs. The genetic effects of the QTLs are 39.6 cm in height and 7.20~9.41 mm in DBH, respectively, The average effects of gene substitution of the markers closely linked with the QTLs are 44.3 cm in height and 8.38~11.81 m in DBH. Under an assumption that the within-family heritability for the growth traits of loblolly pine is less than 0.2, the QTLs account for 26.8% of the additive genetic variance of the progenies. In terms of relative selection efficiency, the individual selection based on QTL markers could be 5 times as high as phenotypic selection. The results in this study indicate that the QTL mapping method with open-pollinated half-sib family could be more practical and applicable to the conventional seed orchard-based selection work than other mapping methods with a single full-sib family, in particular from the viewpoint that it can provide crucial information for within-family individual selection such as breeding value.

An attempt was made to stimulate future research by providing exemplary information, which would integrate published knowledge to solve specific pest problem caused by resistance. This review was directed to find a way for delaying resistance development with consideration of chemical(s) nature, of mixture, rotation, or mosaics, and of insecticide(s) compatible with the biological agents in integrated pest management (IPM). The application frequency, related to the resistance development, was influenced by insecticide activity from potentiation, residual period, and the vulnerability to resistance development of chemical, with secondary pest. Chemical affected feeding, locomotion, flight, mating, and predator avoidance. Insecticides with negative cross-resistance by the difference of target sites and mode of action would be adapted to mixture, rotation and mosaic. Mixtures for delaying resistance depend on each component killing very high percentage of the insects, considering allele dominance, cross-resistance, and immigration and fitness disadvantage. Potential disadvantages associated with mixtures include disruption of biological control, resistance in secondary pests, selecting very resistant population, and extending cross-resistance range. The rotation would use insecticides in high and low doses, or with different metabolic mechanisms. Mosaic apply insecticides to the different sectors of a grid for highly mobile insects, spray unrelated insecticides to sedentary aphids in different areas, or mix plots of insecticide-treated and untreated rows. On the evolution of pest resistance, selectivity and resistance of parasitoids and predator decreased the number of generations in which pesticide treatment is required and they could be complementary to refuges from pesticides To enhance the viability of parasitoids, the terms on the insecticides selectivity and factors affecting to the selectivity in field were examined. For establishment of resistant parasitoid, migration, survivorship, refuge, alternative pesticides were considered. To use parasitoids under the pressure of pesticides, resistant or tolerant parasitoids were tested, collected, and/or selected. A parasitoid parasitized more successfully in the susceptible host than the resistant. Factors affecting to selective toxicity of predator are mixing mineral oil, application method, insecticide contaminated prey, trait of individual insecticide, sub-lethal doses, and the developmental stage of predators. To improve the predator/prey ratio in field, application time, method, and formulation of pesticide, reducing dose rate, using mulches and weeds, multicropping and managing of surroundings are suggested. Plant resistance, predator activity, selective insect growth regulator, and alternative prey positively contributed to the increase of the ratio. Using selective insecticides or insecticide resistant predator controlled its phytophagous prey mites, kept them below an economic level, increased yield, and reduced the spray number and fruits damaged.

Purpose: Preeclampsia is a multisystem human pregnancy-specific disorder. The pathophysiology of preeclampsia is linked with over-stimulation of inflammatory cytokines by placental ischemia via reduced uterine perfusion pressure during pregnancy. Although an increase in tumor necrosis factor (TNF)-alpha has been reported in preeclamptic women, there is little evidence of a relationship between TNF-alpha gene variations and preeclampsia. In this study, we identified a single-nucleotide polymorphism (SNP), C-850T, in the TNF-alpha gene promoter region in Korean preeclamptic women and investigated the association between this SNP and the development of preeclampsia. Materials and Methods: This polymorphism was analyzed in peripheral blood samples from 198 preeclamptic pregnancies and 194 normotensive pregnancies using a SNapShot kit and an ABI Prism 3100 Genetic analyzer. Results: Genotypes and allele frequencies for C-850T did not differ between preeclamptic and normotensive pregnancies. The distributions of genotypes (CC, CT and TT) were 74.3%, 22.2% and 3.5%, respectively, in preeclamptic pregnancies, and 71.6%, 25.8% and 2.6%, respectively, in normotensive pregnancies. The frequencies of the C and T alleles were 0.85 and 0.15 in preeclamptic pregnancies and 0.84 and 0.16 in normotensive pregnancies, respectively. There was no increased risk of preeclampsia in subjects with the CT (OR, 0.83; P=0.44) or TT genotypes (OR, 1.32; P=0.64). Conclusion: We found no differences in the genotypes or allele frequencies of the TNF-alpha gene polymorphism between preeclamptic and normotensive pregnancies. This study suggests that the TNF-alpha gene polymorphism may be not associated with the development of preeclampsia in pregnant Korean women.

A new black seed coat soybean cultivar, 'Daeheug', was developed at the National Institute of Crop Science (NICS) in 2007. The breeding goal for black seed coat soybean is to develop the cultivar with large seed size, high yield, lodging tolerance, and resistance to disease such as soybean mosaic virus (SMV), and bacterial pustule. 'Daeheug' was selected from the cross between 'Daehwang' which had yellow seed coat, large seed size, and late maturity, and 'Milyang 79' which was lodging tolerant, and SMV resistant with medium seed size, black seed coat, and yellow cotyledon. The preliminary, advanced and regional yield trials for evaluation and selection of this cultivar were carried out from 2003 to 2007. It has determinate growth habit, purple flower, brown pubescence, brown pod color, black seed coat, yellow cotyledon, spherical flattened seed shape, oval leaf shape and large seed size (34.3 g/100 seeds). In maturity, 'Daeheug' was 2 days later than the check cultivar 'Ilpumgeomjeongkong'. In the seed quality such as isoflavone contents ($635{\mu}g/g$), and anthocyanin contents ($11.2m{\ell}/g$ of seed coat), 'Daeheug' was better than the check cultivar. It has good adaptability for cooking with rice in ratio of water absorption and seed hardness. Specially, it has good processability for soybean tea with 2.13 absorbance at 530 nm, scavenge activity of DPPH radical was high, and contents of total phenolics was $1,263{\mu}g/m{\ell}$. The average yield of 'Daeheug' was 2.26 ton per hectare in the regional yield trials (RYT) carried out in six locations of Korea from 2005 to 2007.
