  • Present study notes that youth poverty is not only an income deficit, but also a deficit in various dimensions of life such as housing, work and health deficit. Multidimensional poverty is measured by four dimensions: income, work, housing and health. The sample is a 2630 one-person household female youth pooled from the Korea Welfare Panel 10-Year Data. The analysis tool used SPSS statistical program, and the analysis framework was the deficiency rate by dimension, the correlation analysis between deficiency dimension, and the overlapping rate of N dimension poverty. As a result, women's youth in Korea had higher deficit rate in terms of work and housing than other dimensions, and the proportion of women youth who were both poor in work and housing at the same time was also relatively higher than in other cases. Based on these results, this study proposes the construction of customized job services, job matching with small and medium-sized enterprises and allocation of one young woman's household among the targets of long-term chartered housing. Female youth's sharing-economy association should be considered as alternatives.

  • Wastewater-adapted microalgae such as Chlorella vulgaris AG10032, Ankistrodesmus gracilis SAG278-2 and Scenedesmus quadricauda AG10308 are useful biological resources for recovering biofuel and other bio-based materials from wastewater because of their efficient removals of nitrogen and phosphorus from wastewater and their high fatty acid contents in biomass. Although the concentrations of phosphorus typically vary in wastewater environment, very little is known about the effect of phosphorus concentration, especially phosphorus starvation, on microalgal fatty acid synthesis. This is partially due to the lack of methodological establishment for algal fatty acid analysis. In this study, we compared the analysis performances of microalgal fatty acids by two different methods; one is a non-polar GC (gas chromatography) column based method, which is generally used for microbial fatty acids, and the other is a polar WAX-type GC column method, which is typically used for plant fatty acids. And then, we explored the effect of phosphorus concentration levels on fatty acid production in microalgae cultivated from wastewater. As results, the polar WAX-type column method has better ability to separate poly unsaturated fatty acids (PUFA) including $C_{18:3}$ (linolenic acid), and was found to be more applicable in analyzing fatty acids from wastewater-cultivated microalgae than the non-polar column method. The fatty acid characterization by the WAX-type column method revealed little effect of phosphorus starvation on the quantity and composition of fatty acids from wastewater-cultivated microalgae.

  • An experiment was conducted to study the zinc deficiency of rice plant grown on Boeun soil of Korea and on Batangas soil of the philippines. The results obtained are summarized as follows: 1. Batangas soil was deficient in zinc because of the high pH, high organic matter and high calcium. Zinc content of the rice plant grown on Batangas soil was l6ppm. On the other hand, Boeun soil had low organic matter. Zinc content of the rice plant grown on Boeun soil was 33ppm. 2. The top leaf had higher zinc content than any other leaves. Zinc deficiency apparently occured when the zinc content of the rice plant was below 18ppm. 3. The physiologically acid fertilizer such as ammonium sulfate was more advantageous in improving zinc up take than the urea. 4. The zine deficiency was promoted when the Mn/Zn ratio is high, and zinc and manganess interact antagonistically in the growth of rice plant. 5. The zinc deficiency could be overcome by applying zinc chloride and fritted Trace elements to the Batangas soil, and the yield was significantly increased than conrtol.
