The purpose of this study was to examine the relationship between children's self-esteem, peer attachment, parenting attitudes, and children's grit, and to specifically identify the influence of children's self-esteem, peer attachment, and parenting attitudes on children's grit. The characteristics of the survey subjects were identified through frequency analysis and descriptive statistics analysis of the 11th year of the Korea Children's Panel (2018) data, and Pearson's moment correlation coefficient was calculated for correlation analysis between major variables. Multiple regression analysis was conducted to examine the influence of children's self-esteem, peer attachment, and parenting attitudes on children's grit. The research results are as follows. First, children's self-esteem, peer attachment, and parenting attitudes were found to be positively correlated. Second, the child's self-esteem was found to have a positive influence on the child's grit, and among the peer attachment sub-variables, peer trust was found to have an influence, and among the sub-factors of parenting attitude, 'mother' affection/involvement, 'father' Democratic relationships were found to have an effect. In other words, it can be seen that children's self-esteem at the personal level, peer trust at the school level, and maternal affection and paternal relationship at the family level are useful variables that strengthen children's grit. Accordingly, in order to improve children's grit level, we must consider promotion measures through intervention and support at a multifaceted level.

Nowdays, Most of Internet Contents delivered as a compressed file. It gives many advantages like deduction of communication bandwidth and transmission time etc. In case of JPEG Compression, Quantization is the most important procedure which accomplish the compression. In general signal processing, Quantization is the process which converts continuous analog signal to discrete digital signal. As you known already, Quantization over JPEG compression is to reduce magnitude of pixel value in spatial domain or coefficient in frequency domain. A lot of Data Hiding algorithms also developed to applicable for those compressed files. In this paper, we are going to unveil the influence of quantization table which used in the process of JPEG compression. Even thought most of algorithm modify frequency coefficients with considering image quality, they are ignoring the influence of quantization factor corresponding with the modified frequency coefficient. If existing algorithm adapt this result, they can easily evaluate their performances.

The aim of this study is to explore the structural relationship between recognition to environmental factor and place attachment of the users of temple forest trail in Gyeongju National Park, and to suggest political implications on conservation management of National Park from the viewpoint of landscape attachment. Survey with a structured questionnaire was implemented to visitors to the Bulkuksa, a representative temple in Geyongju National Park. Structural equation model was developed from the analysis of collected data. Results showed that place dependence positively affected place attachment in significance, whereas place identity did not significantly affect place attachment. Place attachment was affected rather by place dependence(path coefficient=0.55). Place attachment positively affected the recognition of environmental factors in significance. Landscape use factors compared to facility use factors were affected rather by place attachment(path coefficient=1.01). This result verified the importance of landscape factors of National Park, and suggested a management plan focused on the landscape conservation of forest trail of traditional temple.

This research is a thing about reverse operation about the solar power for location decision and increasing efficiency of the solar power generation equipments. The purpose of this research is reverse operation about the amount of sunshine using the climate and spatial elements. Following the result of correlation analysis, the wind-speed and cloud-amount factor are excluded, because the correlation and significance coefficients are out of value. Each outcome of regression analysis using the other four climate elements, and regression analysis using spatial elements is what the amount of sunshine and the solar altitude are the most influence to the insolation-modeling. Doing the regression analysis based on the precedent result make the result that climate elements have bigger coefficient of regression than spatial elements. This outcome means the climate elements are more influence than spatial elements.

In this study, as an initial study for development of stability analysis program of a double-deck tunnel during life cycle, a structural analysis solver based beam-spring model for the double-deck tunnel is constructed. Effect of parameters(slab supporting type, depth of the tunnel and ground elastic modulus) is analyzed with the beam-spring model. The model is also compared and verified by commercial structural analysis program. It is considered that the slab supporting type affects the integrated behavior with segment lining and influence of intermediate slab on the stability of the tunnel decreases as the tunnel depth increases. The relationship between the ground elastic modulus and the effect of the intermediate slab on the segment lining needs further investigation.

The purpose of this study was to compare the difference between the adaptive and internalizing/externalizing maladaptive behaviors of the sensory processing problemtic group classified from non-disabled preschoolers and to confirms the effects of sensory processing sub-factors on adaptive and maladaptive behaviors. This study participated in 335, 3-6 years typical preschoolers, carried out Short sensory profile, Vineland-II adaptive behavior scales. The study result in the sensory processing showed a significant positive correlation with the adaptive behavior, and a significant negative correlations were found in the internalizing/externalizing maladaptive behaviors. In the t-test, the problemtic group had lower adaptive behavior scores than the typical group. This study confirmed that atypical sensory processing affected not only adaptive behavior, but also internalizing/externalizing maladaptive problems, that sensory processing difficulties were more related to emotional and behavioral issues.

The amount of energy consumed by a transportation system in a city is influenced not just by a transportation system itself but also by city's spatial character. Yet there have been very limited studies on this subject. This study investigates the factors that influence the energy consumption by a transportation system and city's spatial character. The model of an urban area confined within a definite boundary is assumed in order to develop the relationships between the energy consumption and the transportation system. Various assumptions on the character of a city and activities are made. An equation for computation of the energy consumption is derived with such factors as modal split, densities of residents and workers, as well as technological development. Using the equation, sensitivity analyses are performed in order to identify the relationships between energy consumption and influencing factors. It is found that the modal split is the most powerful factor that determines the energy consumption by the transportation system. Yet it is also found that the densities of residents and workers and the technological factors are very important in determining the amount of energy consumption as well.

In this analysis, from the perspective of the business ecosystem, the economic effects of the oil and gas E&P industry were estimated. Australia, Norway, and the US, which are countries that are active in oil and gas E&P projects, and Japan and Korea, which are not, were analyzed. According to the analysis results, every country has a induced production coefficient of the oil and gas E&P industry greater than 1. Norway and the US have formed an industrial ecosystem across all industries, evenly demanding intermediate inputs for the primary, secondary, and tertiary industries. In contrast, Korea and Japan have a very large input ratio from the tertiary industry and an industrial ecosystem centered on the tertiary industry. It should be considered that the high input ratio of certain industry in business ecosystem determine the scale of the induced effect. When the business ecosystem are formed with many industries evenly, and the induced coefficient is high, it is necessary to increase the amount of final demand of the industry to make the effects of coefficient to increase.
