Purpose: This study examined the impact of working environment, job identity, and job satisfaction on turnover intention among child care providers. Methods: Data were collected from a sample of 146 child care providers using self-administered questionnaires from May 1 to July 20, 2014. The data were analyzed with SPSS 18.0. Results: Child care providers had a middle level of job identity, job satisfaction, and turnover intention. Turnover intention among child care providers was significantly predicted by age, job satisfaction, and income satisfaction. Conclusion: These results suggest that intervention and strategy development are needed to decrease turnover intention among child care providers. Exploration of strategies to increase the job satisfaction and income satisfaction are needed, in order to reduce turnover intention.

Axial magnetic field was applied into the hollow anode of plasma torch for the purpose of extension of electrode lifetime. The average arc voltage increased because the arc column became longer, the arc voltage ripple frequency became low. The steady state of arc voltage was removed by applied magnetic filed. The lifetime of electrode was 60 times longer than operation without magnetic field.

Recently, the use of ALC has became increasingly popular. ALC is a unique building material. Because of its cellular nature, it is lightweight, self-insulating, sound and fireproof, as well as insect and mold resistant. Furthermore, ALC is free of VOCs and various fibers associated with wood and glass wool construction. However, ALC have high water absorption, low compressive strength and popout the origin of the low surface strength in its properties. These properties make troubles under construction such as cracking and popout. Thus, this study is to improve the fundamental strength by controls of increasing of admixtures, and grain size. Admixtures make use of metakaolin, silica fume, sodium silicate and sodium hydroxide. From the test result, the ALC using admixture have a good fundamental properties compared with plain specimen. Compressive strength, specific strength and abrasion's ratio were improved depending on increasing admixtures ratio's, and grain size.

It is essential every concrete structure should continue to perform its intended functions, that is maintain its required strength and durability, during the service life. However, deterioration occurs more progressively from the outside of concrete exposed to severe conditions. Deterioration in the concrete structure is due to carbonation and chloride ion attack. Therefore, concrete structure is needed to surface protection for increase durability using impregnant. Impregnant classify into two large groups in polymeric and silicate materials. Silicate impregnant is included silane and alkali silicate(sodium and lithium silicate). Thus, this study is concerned with carbonation and chloride ion resistance of self cleaning hydrophilic impregnant of concrete structure using lithium and potassium silicate. From the experimental test result, lithium and potassium silicate have a good properties as a carbonation and chloride ion resistance. Lithium and potassium silicate make good use of hydrophilic impregnant.

This study analyzes how the environmental values of fashion consumers influence the purchase satisfaction and repurchase intention of eco-friendly fashion products. The survey was conducted from June $1^{st}$ to $30^{th}$ in 2009, and 343 responses were used in the data analysis. The statistical analysis methods were frequency analysis, factor analysis, reliability analysis, and multiple regression analysis. The results show that the environmental values is classified by environment conservative value, economical value, social altruistic value, and egocentric value. The social altruistic value of fashion consumers affects purchase satisfaction of eco-friendly fashion products. The social altruistic value, environment conservative value, and egocentric value affect the repurchase intention of eco-friendly fashion products.

목적： We has proposed a surface coil which has improved SNR compared with the standard head coil. Usually, a cylindrical head coil provide good homogeneity but less SNR than surface coil. A surface coil has better SNR at the expense of image homogeneity. In this paper, a surface coil of transmit-receive mode offers a better SNR as compared with a head coil.

In general, urban railroad in Korea is constructed as a tunnel type under ground due to the various restricted conditions. Passengers in train running through underground tunnel compare to open space are exposed to severe noise environment. In this study, various performance characteristics of many candidate materials are surveyed and analyzed. And some important characteristics are tested. From this study, various performance requirement for noise reduction in railway tunnel were suggested.

In this paper, a new background subtraction algorithm for video based fence monitoring surveillance systems is proposed. We adopt the sampling based background subtraction technique and focus on the two main issues: handling highly dynamic environment and handling the flickering nature of pulse based IR (infrared) lamp. Natural scenes from fence monitoring system are usually composed of several dynamic entities such as swaying trees, moving water, waves and rain. To deal with such dynamic backgrounds, we utilize the confidence factor for each background value of the input image. For the flickering IR lamp, the original sampling based technique is extended to handle double background models. Experimental results revealed that our method works well in real fence monitoring surveillance systems.
