Rural house came into the rapid change through the process of modernization and Saemaul movement in the past. This change continue to the current era, there is a such exotic forms and indiscriminate development of new house and Saemaul housing and existing conventional farmhouse in rural area. Such a phenomenon, ultimately creating disharmony in traditional environment of rural. In this respect, reflecting the location characteristics of the region which is based on the regional characteristics and unique model of rural housing, it is absolutely required for the development of rural housing customized to fit the diversity of modern. With that background, the purpose of the research is to try and find out the changes in rural houses and the transforming characteristics. To achieve this research purpose, this research selected a specialized magazine for architecture. Then, it identified contents which has specific keyword. lastly, it analyze type and contents of house in rural area from selected article. This process make up the rural housing for effective utilization. The result showed that the type of economic activity and residents information directly show the character of the members who located in the new homes after retuning to farming. The polarization of structure was clearly visible by the building time. And, propensity to western-style of major components was very high such as shape and form of housing. However, it was found to prefer to reflect traditional aesthetics in the components of the housing partially. Therefore, more research is needed to reflect of the results of a survey. Also, analyzing the characteristic of rural house’s element and suggesting ways to take advantage in order to present suitable element of modern rural house.

Elemental mercury has a very high volatility allowing easy dissipation from water or soil into air. To better understand how the kinetics of diffusion of elemental mercury through a medium, which is soil in this study, a mercury diffusion column experiment was done. The correlation between temperature and equilibrium concentrations of mercury in standardized soil samples and a pure mercury standard were determined. Total mercury concentrations were analysed using CVAFS. The effect of time and soil depth to the kinetics of mercury diffusion were determined. Differences in mercury concentrations at different sampling probes were observed during the first few gas phase analyses. Equilibrium was reached through the column after 72 hours.

This study was to find out if forest activities affect to children with ADHD and improve their behaviors and social natures. 14 Elementary school students were divided half and designated either experimental group or control group after the preliminary work. Both two groups took prior examinations at the beginning of the program. To the experimental group, forest activity program had been implemented once a week, from 10 a.m. to 12 p.m. for 10 weeks at the woodland path in K Park operated by Seoul city. The results proved to be effective in some lower areas of CPRS and Fair test. Additionally, scores of SSRS increased a bit in all four subdivisions within social indicators, but they were not meaningful in statistics. But the score increases of open area in the scales of PACI were meaningful. Taken together, it indicates that the application of forest activity programs including forest games is highly applicable and efficient supportive treatment for ADHD children.

Miscanthus has been considered as the most promising bioenergy crop for lignocellulosic biomass production. In Korea, M. sacchariflorus and M. sinensis can be found easily in all regions. It is a great advantage to utilize as important species with respect to genetic and cross-breeding programs materials for creation of novel hybrids. For successful breeding programs, it is important to precisely understand the variability of flowering traits among Miscanthus species as breeding parents materials. In this study, flowering traits were observed daily in 960 germplasms of two Miscanthus species (M. sacchariflorus and M. sinensis) for growing seasons over 2 years. The flowering process was divided into three stages. ST (sprouting time) was recorded when first leaf of the plant emerged on soil. FS1 (flowering stage 1) and FS2 (flowering stage 2) were recorded when flag leaf was firstly observed, and 1 cm of panicle was showing on at least one stem, respectively. For 2013 and 2014, the latest germplasms exerted flag leaf, i.e. September 30 (DOY of FS1 164.1) and September 4 (DOY of FS1 141.0) occurred M. sacchariflorus cv. Geodae 1 and M. sacchariflorus cv. Uram collected from Southern Korea (Jeollanam-do), while Miscanthus germplasms collected from northern Korea (Gyeonggi-do) which emerged the earliest flag leaf in July and August, significantly decreased DOY. For DOY from ST to FS2, M. sacchriflorus germplasms ranged from 140 to 190 days, and 110 to 170 days for 2013 and 2014. The highest frequency showed to 160 days for 2013, and 150 days for 2014. In M. sinensis germplasms, the highest frequency showed to 180 days for 2013, and 170 days for 2014. In the results of correlation between the day of years from ST to FS2 for 2013 and 2014, M. sacchriflorus and M. sinensis showed high coefficient of correlation (0.70 and 0.89). It can be supposed that flowering characteristics of Miscanthus are largely affected by the unique phenotypic characteristic of native habitat than environmental factors of the current planted site. This study for flowering traits of Miscanthus may provides an important information in order to expedite the introduction as breeding materials for creation of new hybrid.

This study firstly provides basic data for selection of cultivatable bioenergy grass in barren reclaimed lands applied with solidified sewage sludge. The experimental plots consisted of a plot containing reclaimed land mixed with solidified sewage sludge (MSS 50), a plot covered by solidified sewage sludge (CSS 100), and an original reclaimed soil plot (ORS). The growth, biomass production of bioenergy grasses and soil chemical properties were investigated in each experimental plot for 5 years. The organic matter (OM) and total nitrogen (T-N) content in both MSS 50 and CSS 100 were considerably higher than those in ORS. In bioenergy grasses, M. sacchariflorus cv. Geodae 1 showed an excellent growth and adaptability on reclaimed land applied with solidified sewage sludge. The application of solidified sewage sludge may provided soil nutrition in the reclaimed land due to the fact that bioenergy crops grew better in soils applied with solidified sewage sludge than in untreated soils, and treated soils had higher OM and T-N content than untreated soils. This study suggests that M. sacchariflorus cv. Geodae 1 is the most suitable biomass feedstock crop for biomass production and that solidified sewage sludge may be used as a soil material

Acute tubular necrosis (ATN) is a syndrome of intrinsic renal injury secondary to ischemic or toxic causes without parenchymal damages and usually non-oliguria. A 20-year old man presented with acute renal failure preceded by 2 days of watery diarrhea. He had been anuria for 48hr with intravenous fluid therapy. Oliguria persisted for 10 days and he required hemodialysis support for 6 days before renal recovery. He denied the use of any regular medication and any intravenous drug use. Renal biopsy revealed severe ATN. Histopathologic findings were marked desquamation of proximal tubular epithelial cells with intact distal tubules and normal glomeruli. We report an unusual case of ATN with anuria and clinically severe features.

Hydroureter could occur in a state where the whole ureter was remarkably expanded. The causes of occurrence are anatomi-cal urinary tract obstruction or vesicoureteral reflux, and it could occur unilaterally or bilaterally according to its reason. A 38-year-old man presented with left flank pain. Abdominal CT showed a severely atrophied left kidney and a large retroperi-toneal cyst near the left kidney. The pathologic finding showed that the cyst wall is composed of transitional epithelium, lamina propria, muscle, and adventitia, and final diagnosis was hydroureter. The unilateral marked hydroureter misdiagnosed as a retroperitoneal cyst was quite rare. We report on this rare case with literature.
