The gender differences of mathematics achievement exists in many counties in the world. Some Chinese scholars think that the differences also exist in China. The researchers explain the gender differences of mathematics learning mainly from the individual psychology and education. This paper, firstly, introduces an investigation of the gender differences of mathematics achievement in grade 1-9 in three areas (Hefei urban area, Cuozhen area, and Chenji area) of Hefei in China. The investigation found that the gender differences of mathematics achievement exist but are different in these areas. Then, the results are explained from the theory of the gender socialization.

Copper pipes have been widely used as components of System Air-Conditioner due to high thermal conductivity. This system consists of 150 pipes, which are approximately 10m long in total. Dimensional changes occur during pipe processing such as expansion, reduction and bending. This processing induces changes in length of pipes and makes dimensional differences from original pipes. The summation of the differences of pipes components leads to make huge cumulative dimensional differences. The cumulative differences can cause serious problems such as crack, refrigerant leakage. However the differences have not been considered so far. To satisfy target quality of the system, it is essential to predict and calibrate the differences. In this paper, the changes in dimension were predicted using FEM and it was found that cumulative differences could cause indesirable stress during assembly process. As a result, dimensional differences or indesirable stress could be reduced using the proposed method.

Mothers play a major role in children's consumer socialization but little is known about differences in mother's consumer socialization tendencies and the antecedents causing the differences. This study addresses two research questions: First, what are the underlying dimensions of mother's consumer socialization? Second, what are the antecedent variables causing differences in mother's consumer socialization tendencies; can parental style, consumption-related attitudes (attitude toward marketplace and ads., attitude toward consumerism and consumption-oriented attitude) be used as a conceptual basis for hypothesizing these differences? The findings of this research were as follows: 1. Factor analysis suggested five underlying dimensions of mother's consumer socialization of children; Mother-child communication about consumption, Mediation of media, Reaction to purchase requests, Restriction of allowances and Restriction of consumption. 2. The differences in the mother's consumer socialization tendencies among different parental groups matched the differences in child-rearing behaviour suggested by Developmental Psychology and this provided support for expected relationships between general-consumer socialization tendencies, as measured by mothers' behaviour. 3. Differences were found on all factors according to mothers consumption-related attitude. This provided support for the expectation that mothers' consumption related attitudes are important antecedent variables causing differences in consumer socialization tendencies. Some implications and directions for future research were discussed.

Just as it is possible to distinguish people by using physical features, such as fingerprints, irises, veins, and faces, and behavioral features, such as voice, gait, keyboard input pattern, and signatures, the an IoT device includes various features that cannot be replicated. For example, there are differences in the physical structure of the chip, differences in computation time of the devices or circuits, differences in residual data when the SDRAM is turned on and off, and minute differences in sensor sensing results. Because of these differences, Sensor data can be collected and analyzed, based on these differences, to identify features that can classify the sensors and define them as sensor-based device DNA technology. As Similar to the biometrics, such as human fingerprints and irises, can be authenticatedused for authentication, sensor-based device DNA can be used to authenticate sensors and generate cryptographic keys that can be used for security.

This study is for examining the differences of perceived stresses and family strengths between the parents according to socio-demographic backgrounds(age, educational level, income and the degree of disorder) of the parents having mentally retarded children. The results were as follows. First, in the overall perceived stress level, there was no difference between fathers and mothers, but when compared in stress areas, fathers experience more distresses in general interpersonal areas than mothers. Fathers also shows differences according to the degrees of their income and their perception about disorder compared with mothers showing differences according to the degree of income. Second, there were no differences in family strengths perceived by both fathers and mothers, but were significant differences according to the level of education and income. Another words, higher the education and income level, higher is their family strengths level. Third, there were positive correlations between the perceived stresses and family strengths, and significant differences in family strengths according to the stress level(higher/lower part of the group). In other words, when the perceived stress level is high, the level of perceived family strengths is low.
