Stator insulation quality assessment for high voltage motors is a major issue for the reliable maintenance of industrial and power plants. To assess the condition of stator insulation, nondestructive tests were performed on the sixty coil groups of twelve motors. After completing the nondestructive tests, the AC voltage applied to the stator winding was gradually increased until insulation failure in order to obtain the breakdown voltage. The stator winding of each motor was classified into five coil groups; one group with healthy insulation and four groups with four different types of artificial defects. To analyze the breakdown voltage statistically, Weibull distribution was employed for the tests on the fifty coil groups of ten motors. The 50th percentile values of the measured breakdown voltages based on the statistical data of the five coil groups of ten motors were 26.1kV, 25.0kV, 24.4kV, 26.7kV and 30.5kV, respectively. Almost all of the failures were located in the line-end coil at the exit of the core slot. The breakdown voltages and the types of defects showed strong relation to the stator insulation tests such as in the case of dissipation factor and ac current. It is shown that the condition of the motor insulation can be determined from the relationship between the probability of failure and the type of defect.

The purpose of this study is to investigate prior thinking and posterior thinking formation of children and adolescents in sinking objects. The subjects consisted of twenty eight, 9- and 11-year old children and fourteen, 13-year old adolescents selected from one elementary school and two middle schools. The transcripts were analyzed to classify children and adolescents'prior thinking and posterior thinking frequency, reasoning response(evidence based response, idea based response) and reasoning method(valid method, invalid method). The data were analyzed by frequency, percentile, mean and standard deviation,1 test, ANOVA. Major findings were as followings: 1. Children and adolescents have already had prior thinking in sinking objects. 2. Children and adolescents applies their prior thinking to posterior thinking formation process. 3. There were significant differences in children and adolescent'posterior thinking formation process, especially choices in objects and reasoning methods depending on age. 4. There were significant differences in children and adolescents'reasoning response depending on presented evidences types.5. Through the experimentation, children and adolescents'prior thinking was different from their posterior thinking. There were significant differences in differences between the prior thinking and posterior thinking depending on age.

The purposes of this study were to identify the household's financial status by life cycle stage and no analyze contributing factors to financial planning for retirement preparation among Korean marred couples. For these purpose, 2074 married couples those being under 55 and having either single earner or dual earners were selected, and total sample was divided into three stages; young-aged(＜35), middle-aged(35-44) & old-aged(45-54). Statistics were frequencies, means, percentile, and logistic analysis. The results were as follows. First, old-aged had higher level of total income, total expenditure and total assets than either young-aged or middle-aged. In addition, households those holding private pensions were likely to have higher total income, total expenditure and total assets than those owning no private pension. while middle-aged had a highest total debts. Second, gini coefficients of total income and total expenditure between three aged groups were similar, but old-aged had the highest gini coefficient of total assets and total debts. In particular, gini coefficients of total assets and total debts of households those having no private pension were greater than those holding private pensions. third, contributing factors to private pension ownership of young-aged were family & household-related factor and financial factor, middle-aged's factors were household head's characteristics and financial factor. Also, old-aged's factors were household head's characteristics, family & household-related factor and financial factor.

The purpose of this study was to investigate factors related to the parental role in satisfaction and parenting behaviors. The subjects were 102 employed mothers and 110 unemployed mothers of 5-year-old children living in Seoul, Korea. The measures were questionnaire, the Parental Role Satisfaction Scale and the Parenting Behaviors Scale. The data were analyzed by Cronbach's ${\alpha}$, frequency, percentile, mean, correlation, multiple regression and Chow-test. Consistent with Belsky's model of the determinants of parenting, the parental role satisfaction and parenting behaviors of both employed and unemployed mothers were influenced by child characteristics, parent characteristics, and family factors. Results showed that the parental role satisfaction of both employed and unemployed mothers was correlated to child's birth order, temperament and health of child, mothers' and fathers' age, fathers' educational level, and family income. Parenting behaviors were also correlated to sex of child, child's birth order, temperament of child, parental educational level, and family income for employed mothers and to health of child, mothers' and fathers' age, mothers' educational level, and family income for unemployed mothers. Especially, father's age for employed mothers, and child's temperament for unemployed mothers, were the most strongly related variables for parental role satisfaction. On the other hand, family income for employed mothers, and fathers' age for unemployed mothers were the most strongly related variables for parenting behaviors.

In order to evaluate the contamination and health risk, levels of six hazardous elements i.e., Cr, Ni, Cu, As, Cd and Pb in soils of 12 different land-uses were measured. The average concentration of Cu, Cr, Ni, Pb, As and Cd in soils were 267, 239, 206, 195, 58 and 16 mg/kg, respectively. Levels of each metal exceeded the environmental action level for soils, which could pose significant risk to human. The metal concentrations were subsequently used to establish hazard indices (for adults and children) where the 5th and 95th percentile values were used to derive the hazard index through different exposure pathways (ingestion, dermal contact and inhalation). Considering the total exposure through each of the three pathways, the hazard index elucidates that there was a potency of non-cancer risk at most of the sites for both the adults and children. The findings of this study suggested that different land-use soils were severely contaminated with hazardous elements and attention is needed on the potential health risks to the exposed inhabitants.

Compared to previous in-vitro test, FE model showed reliable motion patterns. A finite element model of a 50th percentile male neck was developed to study the mechanics of whiplash injury while the rear impacts. The model was consisted of the whole cervical vertebrae including part of occipital, intervertebral discs. which were modeled using linear viscoelastic materials and posterior elements. The sliding interfaces were defined to simulate contact phenomena in facet joints and in odontoid process. All ligaments and atlanto-occipital membrane were modeled as nonlinear bar elements. Only muscle elements were not considered. Motion of each cervical vertebra was obtained from the dynamic simulation with a MADYMO model for 15 km/h $40\%$ rear end offset impacts. Soft tissue neck injury(STNI) was investigated with a developed FE model. In FE model analysis, the high stress was appeared at C3/C4 disc in offset impact. Further research is still needed in order to improve the developed neck FE model for many different crash patterns.

The purpose of this research is to examine reasons and evaluate strategies implemented by the Indian banking industry in tackling jay-customers in general and in light of the recent demonetization in particular. After a thorough germane literature and theoretical framework on jay-customers and Indian banking industry, researchers framed a well-structured questionnaire for collecting banking employees opinions along with a set of questions framed to conduct in-depth personal interviews with banking customers. The collected data were summarized, coded, and controlled by using Software R and the selected hypotheses were analyzed by the observance of percentile values. More than 90 percent of banking employees said lack of proper supply of cash from the Reserve Bank of India is the major reason for this kind of customer behaviour and shockingly 95 percent of banking customers expressed backdoor preference given by banking employees to some big customers is the major reason. The research confined only two state capitals Amaravati and Bangalore in India and covered only two largest banks one in public and private sector. The research provides useful insight into the crucial reasons for jay-customers' behaviour from the dyadic perspective of both employees and customers of the Indian banking industry.
