Objectives: The objective of this study was to examine the effect of mentoring function on job satisfaction, organization commitment, and turnover intention in the newly employed dental hygienists. Methods: Two hundred and fourteen dental hygienists in Daegu and Gyeongbuk completed a self-reported questionnaire from January to May 2013. The instrument for the questionnaire consisted of mentoring function, mentoring personality, job satisfaction, organizational commitment, and turnover intention. The data were analyzed by frequency analysis, ANOVA, correlation analysis, and multiple regression analysis. Results: The longer duration of the mentoring for the newly employees strengthened job satisfaction and organization commitment. The mentoring function had a positive effect on job satisfaction and organization commitment, and decreased turnover intention. The higher quality of personality overcome the turnover intention. Conclusions: The mentoring is very important to enhance the job satisfaction and organization commitment in the newly employees. Loner duration of work(${\beta}=.268$, p=0.008) explained higher job satisfaction. Higher quality of personality(${\beta}=0.279$, p<0.001) also had higher job satisfaction. The explanation power of the model was 36.5% and the revised model explanation was 35.6%. The effective mentoring is closely related to job satisfaction and organization commitment and it can reduce turnover intention.

Generally, fragility curve has been used in predicting failure of structures due to seismic actions. In this research, the method of drawing fragility curve has been applied to evaluating success/failure of structures and satisfactory/unsatisfactory of concrete mixture performance based on material parameters. In the paper, a detailed explanation of the procedure of drawing fragility curve based on material parameter has been introduced. Fragility curve generating procedure includes generation of virtual data points from limited number of actual data points by bell curve implementation, determination of success/failure status of each data point by assigned criterion, and completion of final fragility curve. For practical applications, workability of concrete mixture content based on "unit water" has been used to obtain fragility curve. Detailed explanation of fragility curve drawing procedure for material parameters is presented.

In this article we studied the role of spreadsheet in teaching function and modeling activity by some examples and students' activity performed by the six 10th graders. We especially focused the role of spreadsheet in understanding of various kinds of functions and the families of functions, and in the explanation of the given modeling problem situations. The functions of automatic copy, graphic and the cell reference of spreadsheet can be used to make students observe the causes and effects of changes of the various kind of mathematical representations of functions such as algebraic formulas, tables and graphs. Especially those functions give students a chance to identify family of functions by changing the parameters and this may lead them to the discovery of mathematical facts. In modeling activities they play a key role in the stages of the analysis of the model, explanation of the results of model and conjecture of the real world situations. As well as they make students find the rules underlying in the real world by making spreadsheet as simulation environments, which are almost impossible to make in paper and pencil environments, and give them a chance to justify their findings using mathematics.

The calcium-induced structural changes in the skeletal muscle regulatory protein troponin C (NTnC) involve a transition from a ‘closed’to an ‘open’structure with the concomitant exposure of a large hydrophobic interaction site for target proteins. Structural studies have served to define this conformational change and elucidate the mechanism of the linkage between calcium binding and the induced structural changes. There are now several structures of NTnC available from both NMR and X-ray crystallography. Comparison of the calcium bound structures reveals differences in the level of opening. We have considered the concept of a flexible open state of NTnC as a possible explanation for this apparent discrepancy. We also present simulations of the closed-to-open transition which are in agreement with the flexibility concept and with experimental energetics data.

Background : The purpose of this study is to provide the basic data according to cognitive function, that will help activities of daily living of the elderly through the comparative study of activities daily living and functional training. Methods : The subjects of this study 122 patients 65 years old or more ADL and cognitive function assessment was evaluated. They were registered in the Elderly in nursing homes and welfare centers, located in Gyeonggi. All study participants had a sufficient explanation for the purposes of research and evaluation methods and procedures for the elderly. The survey period 17 October to 11 November 2011 was conducted through face-to-face survey was conducted. Results : Cognitive function according to the K-MMSE score of 24 points or more, 23 to 18 points, 17 points or less were classified. Ability to perform activities of daily living (personal hygiene, bathing, toilet use, stair climbing, dressing, stool control, urinary control, gait, chair/bed, etc.) according to the degree of cognitive function by evaluating the ability to perform daily living compared results in all variables were statistically significant (p<.5). Conclusion : As a result, the higher cognitive functions can be seen that the higher the ability to perform activities of daily living.

An incongruity is underlined about the analysis of Timoshenko beams subjected to concentrated loads modelled through the use of generalized functions. While for Euler-Bernoulli beams this modeling always leads to effective results, on the contrary, the contemporary assumptions of concentrated external moment, interpreted as a generalized function (doublet), and of shear deformation determine inconsistent discontinuities in the deflection laws. A physical/theoretical explanation of this not-neglecting incongruity is given in the text.

For the production of complicated plastic parts in a cycle, a mold is needed.. The basic tasks of a mold are accommodation and distribution of the resin, shaping and cooling the melt and ejection of the molding. To achieve these goal a mold has several important parts and we classified types of molds. The 6 different major functions of a mold are explained and several types of molds are shown in her. I hope these explanation will help to understand injection molds for a design engineer.

This paper used the majority function to digitally filter back-electromotive force as an explanation of the Brushless DC MOTOR control algorithm. The cause and improvement of motor noise, which are operating in close proximity to high frequency sources, did not use conventional low pass filter and comparator elements. Also, they repeatedly output a noise-free BEMF signal for the input value of the majority detection filtering. These filtering steps can help reduce costs and minimize the area of a PCB by requiring relatively little hardware.

TRIZ, the Russian acronym for Theory of Inventive Problem Solving(TIPS) is introduced in this paper. The core concepts of TRIZ such as levels of inventions, patterns of technological evolution, technical and physical contradictions are explained. It is also discussed that how TRIZ can be applied to quality function deployment in order to overcome negative correlations(i.e., trade-off relationships) between engineering characteristics. Some case examples are presented for the purpose of explanation.

Purpose: This study was done to examine the relationship of successful aging, depression, and family function in rural elders. Method: A descriptive correlation study design was used and data of the study were collected from 272 people who were overn 65 years of age and lived in a rural community. Result: The mean score for successful aging was $2.28{\pm}0.46$ points of a maximum 3 points. The elders showed a moderate degree of family function ($6.98{\pm}2.83$ points out of 10 points). The mean score for depression was $6.13{\pm}3.75$ points out of 15 points. There was a statistically significant correlation between successful aging and both depression (r=-.659, p<.001) and family function (r=.621, p<.001). Stepwise regression analysis was done to verify factors influencing successful aging. Depression was the dominant factor accounting for 43.2% of the total variance, followed by family function and age in that order. Inclusion of all of the study values resulted in an explanation power of 61.7%. Conclusion: The study results suggest that the provision of individual socio-psychological, and economic measures is important to promote successful aging in rural areas which are different in terms of socio-cultural as well as regional factors compared to urban areas.
