This study was performed to estimate total contents of arsenic (As) by stepwise multiple-regression analysis using chemical properties and extractable contents of metal in paddy soil adjacent to abandoned mines. The soil was collected from paddies near abandoned mines. Soil pH, electrical conductively (EC), organic mater (OM), available phosphorus ($P_2O_5$), and exchangeable cations (Ca, K, Mg, Na) were measured. Total contents of As and extractable contents of metals were analyzed by ICP-OES. From stepwise analysis, it was showed that the contents of extractable As, available phosphorus, extractable Cu, exchangeable K, exchangeable Na, and organic mater significantly influenced the total contents of As in soil (p<0.001). The multiple linear regression models have been established as Log (Total-As) = 0.741 + 0.716 Log (extractable-As) - 0.734 Log (avail-$P_2O_5$) + 0.334 Log (extractable-Cu) + 0.186 Log (exchangeable-K) - 0.593 Log (exchangeable-Na) + 0.558 Log (OM). The estimated value in total contents of As was significantly correlated with the measured value in soil ($R^2$=0.84196, p<0.0001). This predictive model for estimating total As contents in paddy soil will be properly applied to the numerous datasets which were surveyed with extractable heavy metal contents based on Soil Environmental Conservation Act before 2010.

Purpose: This study was performed to identify the nursing needs of home-dwelling breast cancer patients based on counseling contents. Methods: Descriptive research was conducted with content analysis. This study included 185 patients who underwent treatment for breast cancer in a tertiary hospital. The data were collected using personal counseling via telephone or face-to-face between March 2011 and July 2013. A total of 536 counseling contents were used in the analysis. Inductive content analysis was used to analyze the contents related to nursing counselling. Results: According to the results. the most frequently reported nursing needs was symptom management, followed by information needs and supportive intervention needs; symptom management needs included symptoms related to chemotherapy, daily living, surgery, and medication side effects; information needs included treatments, medication, clinical tests, and alternative therapies; and supportive intervention needs were related to emotional and social aspects. Conclusion: Our findings suggest that nursing interventions for home-dwelling breast cancer patients should be designed and provided with a consideration to these relevant nursing needs.

English textbooks play essential roles in the whole English education context, the analytic study on English textbooks is very important in English education tasks. The purpose of this study is to analyze the expressive functions in the middle school English textbooks on the basis of the 6th national curriculum characteristics and the textbook analysis theories. The results of the expressive language function analysis are as follow: the teaching contents designed for the expressive language functions are not varied, but concentrated on the specific teaching types, and the teaching contents for the expressive language functions are not graded according to the students' development principles stated clearly in the 6th curriculum. The results of the English textbook analysis on the basis of the expressive language function analysis show that the 6th curriculum has some problems in itself and the middle school textbooks do not conform to the 6th curriculum principles. Therefore we need to improve the teaching contents for language functions by means of developing various types of teaching language functions.

Polyester type polyurethane foam modified with acrylic polyol was prepared by quasi prepolymer method. Thermal and dynamic mechanical properties of polyurethane foam were analysed by thermal gravimetric analysis(TGA) and dynamic mechanical analysis(DMA). Also, glass transition temperature was measured by differential scanning calorimeter(DSC). As acrylic polyol contents were increased, thermal stability measured by TGA was slightly decreased. Storage modulus was increased and tan delta was decreased with increasing of acrylic polyol contents.

In this paper, contents related to problem solving in 7th elementary mathematics curriculum analyzed in five aspects: problem solving stages, problem solving strategies, problems, problem posing, and assessment on problem solving abilities. From the results and processes of analysis, following conclusions are obtained: First, it is difficult to say the contents related to problem solving in 7th elementary mathematics curriculum are prepared organically. Second, it is difficult to say that contents related to problem solving in 7th elementary mathematics curriculum reflect results of recent researches.

To evaluate short rotation forestry candidates, seven clones of Salix hultenii were investigated as focused on chemical compositions and energy contents. There were significant variations in chemical compositions and energy contents among different clones. Variations in hot-water extractives content were 6.6-16.0% and 19.6-25.4% variation in lignin content. In carbohydrate compositional analysis, xylan contents were 7.5-13.1% with variation among different clones. Higher heating values were 17.69-20.02 MJ/kg.

Air voids in hardened concrete have an important influence on concrete durability such as resistance of freezing and thawing, permeability and surface scaling resistance. Linear traverse method and point count method in ASTM standard method have been widely used to estimate the air void system in hardened concrete. However, these methods are not used at present time, because they are is exhausted much time and effort. In previous study, air voids system of concrete was estimated by spacing factor. The purpose of this study organizes image analysis method by analyzing air contents, air voids distributions by diameters, air voids system as well as spacing factors after hardened concrete. The experimental variables institute of depth of specimen(top, middle, bottom), air contents(AE contents 0, 0.01, 0.03%).

To consider sulfate resistance of cement pastes and motars for 3 types of portland cements which have different $C_3A$ contents an silicate ratio($C_3S/C_2S$), they were immersed in 5% sodium sulfate solution for 400 days. SEM analysis and ($Ca(OH)_2$ contents of cement pastes, and compressive strength and length change of cement mortars, were performed to investigate the effects of ($C_3$ and ($Ca(OH)_2$ contents. According to the results of this study, low heat portland cement pastes, and compressive strength and length change of cement mortars, were performed to investigate the effects of C3A and ($Ca(OH)_2$ contents. According to the results of this study, low heat portland cement had a good sulfate resistances because of a small quantity of gypsum and ettringite due to less ($Ca(OH)_2$ contents. However, ordinary portland cement had an adverse result. This was also confirmed by SEM analysis.
