The purpose of this study was to investigate the effects of preschooler's self-regulation and maternal parenting behavior on preschooler's game immersion. Subjects were 253 4- to 5-year-old preschoolers(118 boys, 135 girls) and their mothers. Data were analyzed by descriptive statistics, t-test, correlation analysis and stepwise multiple regression analysis. The major findings are summarized as follows: (1) preschooler's game immersion differed from preschooler's gender. Boy preschooler had higher score than girl preschooler in game immersion. (2) Both boy and girl preschooler's game immersion was negatively correlated with preschooler's behavioral regulation and emotional regulation, maternal rational guidance, limit-setting and affection. (3) The most influential factor on boy preschooler's game immersion was behavioral regulation. On the other hand, the most influential factor on girl preschooler's game immersion was emotional regulation, and the next influential factor was maternal affection. Results of this study indicate that self-regulation enhancement program should be developed and mothers should be more affective with their preschoolers in order to prevent preschoolers' game immersion.

Direct Numerical Simulation(DNS) of turbulent mass transfer in fully developed turbulent pipe flow has been performed to study the effect of wall boundary conditions on the concentration fields at $Re_{\tau}$=180 based on friction velocity and pipe radius. Fully developed turbulent pipe flows for Sc=0.71 are studied with two different wall boundary conditions, namely, constant mass flux and constant wall concentration. The mean concentration profiles and turbulent mass fluxes obtained from the present DNS are in good agreement with the previous numerical results currently available. To investigate the effects of wall boundary condition on the turbulent mass transfer, the mean concentration profile, root-mean-square of concentration fluctuation, turbulent mass fluxes and higher-order statistics(Skewness and Flatness factor) are compared for the two cases. Furthermore, the budgets of turbulent mass fluxes and concentration variance were computed and analyzed to elucidate the effects of wall boundary conditions on the turbulent mass transfer.

This paper presents the psychoacoustic analyses on the vehicle interior, noise generated when accelerating. Following the objective quantification for vehicle noises of different classes, the subjective decision process by the jury test is adopted to interrelate these results based on two different approaches. In particular, the paired comparison method is employed in assessing the sound quality in terms of the quietness, the powerfulness, and the pleasantness of the human auditory sensation. Special attention is paid to the physical interpretation of psychoacoutic parameters and their interrelation to the subjective assessment scores. In order to ensure the integrity of statistics of the survey, various tests are performed. The results show that the consistency of the "quiet" sensation is far higher than that of the "powerful" and the "pleasant" sensations. Also, it is found that the most significant parameter determining these feelings turns out to be the inherent loudness of the noise instead of the conventional indicators such as the weighted sound pressure level. It may be concluded that the psychoacoustic analysis offers more realistic evaluation for vehicle noise and assists the improvement of NVH more efficiently.ement of NVH more efficiently.

Purpose: This study was to examine the relationship between health perception, prenatal care behaviors and health promoting behaviors of unmarried pregnant women. Method: The subjects were 97 unmarried pregnant women. The data was collected through personal interviews using a questionnaire. Adjusted instruments were the health perception scale developed by Ware, prenatal care behavior scale developed by Lee, and health promoting behavior scale developed by Pender. Data was analyzed by descriptive statistics, t-test, ANOVA, and the Pearson correlation coefficient with SPSS program. Result: The mean score of health perception was 3.3, and Resistance-Susceptibility was the highest. The mean score of prenatal care behaviors was 2.9, while that of health promoting behaviors was 2.5. The relationship between health perception and prenatal care behaviors was significant(r=0.268, p=.008). The relationship between prenatal care behaviors and health promoting behaviors was also significant (r=0.633, p=.000). Conclusion: The higher the health perception of unmarried pregnant women, the more they are concerned about good prenatal care behaviors. Unmarried pregnant women did well on health promoting behaviors when they had are high degree of good prenatal care behaviors. Therefore, in order to promote positive health perceptions of unmarried pregnant women, it is necessary to develop and adjust various education and supporting programs.

In this paper, we propose a predictive resource metric region (RMR) based radio resource metric estimation (RRME) mechanism, which utilizes a resource metric mapping function (RMMF), both of which permit efficient inter-working between the physical layer and higher layers for envisaging multimedia service applications over a CDMA communication system platform. The RMR can provide the acceptable resource region where QoS and acceptable link quality can be guaranteed with an achievable resource margin to be utilized in terms of capacity margin, the degree of confidence (DCL) of user, second-order statistics of Eb/Io. With predicted capacity margin and variance, DCL can deliver decision parameters with which an adaptive QoS based admission control can perform well taking capacity and resource availability into account in a dynamic and predictive manner. Combined with advanced techniques such as adaptive modulation or rate control and power control, the proposed mechanism can adjust the conventional stringent link quality information efficiently, and deliver accurate information of the resource availability. Thus, these can guarantee the maximization of resource utilization of multimedia service applications.

This study analyzed the effect of consumer value and unethicality on the type of consumer complaint behaviors. Despite the obvious importance of the research on consumer complaint behaviors focused on consumer's inherent personality, there is relatively little work done. The purpose of this study is to analyze the determinants of consumer complaint behaviors in order to improve consumers' well-being and develop the market condition. The 1,050 respondents are finally analyzed using the descriptive statistics, factor analysis, and multinominal logit model. Consumer value and unethicality are significant effect on the type of consumer complaint behaviors such as no action, private action only, public action only, and both private and action. The orientation of achievement and pleasure among consumers' value is associated with the higher level of complaint behaviors compared with no action. In terms of consumers' unethicality, no harm unethicality is associated with the types of each consumer complaint behavior except no action. On the other hand, both proactive and passive unethicality increase the possibility of no action. The policy implications of the consumer education are suggested as well as the directions of customer management strategies in the business sector.

Objectives: The purpose of this study is to parenting attitudes perceived by adolescents into different groups and to examine the impact of sub-factors of parenting attitudes on smart phone addiction. Methods: Data was collected by distributing questionnaires to high school students located in the nationwide regions and a total of 1,020 people were surveyed. Inconsistent parenting attitudes were divided into the consistent group and inconsistent group to carry out descriptive statistics, multiple regression, and path analysis. Results: In both the consistent and inconsistent parenting attitude groups, it was found that among the sub-factors, interest(p<.01) had the biggest impact on smart phone addiction. Inconsistent parenting attitude group was found that smart phone addiction levels in adolescents were more higher than consistent parenting attitude group. Conclusions: Through the above results, it was confirmed that smart phone addiction to directly impact parenting attitude. This implies that when raising their children, parents should display consistent attitudes in order to prevent addictive smart phone usage among adolescent.
