The purpose of this study was to examine validity of the Korean-Child Behavior Checklist: K-CBCL) as measures for emotional and behavioral problems for use with children with autism spectrum disorders. In present study, the factor of the K-CBCL was investigated, using data of 248 children with autism spectrum disorders, with 11.17 mean ages. The two factor model of Internalizing problems (Withdrawn, Somatic Complaints, Anxious/Depressed) and Externalizing problems (Delinquent Behavior, Aggressive Behavior) was investigated by the confirmatory factor analysis. The two factor model of K-CBCL was adequate for children with autism spectrum disorders. The inter-item consistency for the sub-factor of K-CBCL demonstrated on adequate reliability of the measure. Although the inter-item consistency of Withdraw, Social problems, Delinquent Behavior was not acceptable, the inter-item consistency of Internalizing, Externalizing and total problems were good. This results supported validity and reliability and suggested that K-CBCL is used to assess for emotional and behavioral problems in children with autism spectrum disorders.

Pseudo-Brayton cycle is defined as an ideal Brayton cycle admitting the difference between heat capacities of working fluid during heating and cooling processes. The endo-pseudo-Brayton cycle which is a pseudo-Brayton cycle with heat transfer processes is analyzed with the consideration of maximum power conditions and the results were compared with those of the endo-Carnot cycle and endo-Brayton cycle. As results, the maximum power is an extremum with respect to the cycle temperature and the flow heat capacities of heating and cooling processes. At the maximum power condition, the heat capacity of the cold side is smaller than that of heat sink flow. And the heat capacity of endo-Brayton cycle is always between those of heat source and sink flows and those of the working fluids of pseudo-Brayton cycle. There is another optimization problem to decide the distribution of heat transfer capacity to the hot and cold side heat exchangers. The ratios of the capacies of the endo-Brayton and the endo-pseudo-Braton cycles at the maximum power condition are just unity. With the same heat source and sink flows and with the same total heat transfer caqpacities, the maximum power output of the Carnot cycle is the least as expected, but the differences among them were small if the heat transfer capacity is not so large. The thermal efficiencies of the endo-Brayton and endo-Carnot cycle were proved to be 1-.root.(T$_{7}$/T$_{1}$) but it is not applicable to the pseudo-Brayton case, instead it depends on comparative sizes of heat capacities of the heat source and sink flow.w.

Cluster analysis has proven to be a useful tool for investigating the association structure among genes and samples in a microarray data set. We applied several cluster validation measures to evaluate the performance of clustering algorithms for analyzing microarray gene expression data, including hierarchical clustering, K-means, PAM, SOM and model-based clustering. The available validation measures fall into the three general categories of internal, stability and biological. The performance of clustering algorithms is evaluated using simulated and SRBCT microarray data. Our results from simulated data show that nearly every methods have good results with same result as the number of classes in the original data. For the SRBCT data the best choice for the number of clusters is less clear than the simulated data. It appeared that PAM, SOM, model-based method showed similar results to simulated data under Silhouette with of internal measure as well as PAM and model-based method under biological measure, while model-based clustering has the best value of stability measure.

This research is to investigate the effect of teenagers' motivating factors on their own self-efficacy and school-life satisfaction. Positive analysis of data was made based upon the theoretical background. Also, the casual relation between the motivating factors of teenagers and their self-efficacy and school-life satisfaction was verified. The result of the study was as follows: stress, family effect, and mass communications had an effect on intrinsic motivation and extrinsic motivation. The intrinsic motivation had an effect on the school-life satisfaction, and the extrinsic motivation was revealed to have an effect on the self-efficacy and school-life satisfaction. Students' self-efficacy also influenced their school-life satisfaction. This study suggested a few methods to improve teenagers' self-efficacy and their school-life satisfaction through the motivating factors.

Although the matching Pursuit is effective for video coding at low bit rate, it has a Problem since it needs much more calculation than the conventional block-based video coding method. The proposed fast matching pursuit method reduces inner product calculation that takes the most part of entire calculation by utilizing the symmetry of the absolute values of the one-dimensional Gator dictionary bases, the modified dictionary which allows faster matching without causing image quality degradation, and a Property of the two-dimensional Gabor dictionary that can be grouped in advance to four classes according to its frequency characteristics. Proposed method needs only about 1/8 of multiplications compared to the well-known separability-based fast method proposed by Neff.

This paper describes external and internal stability of reinforced earth wall using large-scale modular block and geogrid reinforcement. The evaluation for external and internal stability was conducted to analyze effect of wall height, reinforced soil (or backfill soils) and reinforcement strength. The external stability showed that the analysis cases were satisfied with design criteria, when the required minimum length and vertical spacing of reinforcement were 0.7H and 1m, respectively. The internal stability conformed that some cases were satisfied with design criteria in $25^{\circ}$ of internal friction angle of reinforced soil. Expecially, it will be applicable as wall structure considering a structural stability and economic efficiency based on evaluation of internal stability.

To identify the relationship between instructor's image and participation motive, this study conducted a research on 293 elderlies over 65 at 6 sports centers located in Seoul, Gyeonggi, and Incheon regions. The research results were as follows. First, in the image of instructor based on demographic characteristic, gender showed significant difference with instructor's talent while gender showed significant difference with instructor's talent, instructing image, and living image. Also, the sports type had significant difference with all subfactors of instructor image. Secondly, in the participation motive based on the demographic characteristic, gender showed significant difference with internal motive while age and sports type demonstrated significant difference with all subfactors of participation motive. third, the instructor image had significant influence on both internal and external motive. While instructing image and human relationship image had significant difference in internal motive, the external motive showed significant difference with instructor talent, living image, and human relationship image. thus, the research result showed that instructor's image is a significant variable which enhances elderly's motive for participating in life sports.

This thesis studied about the expression of the conflict in DongraeYaroo. Study perspective was time and passion. Time refers to a change in the time to move to the current from the past. As in the study was the change in the phase and values of the characters occurred. Passion is an act which is scheduled departing from the spirit moves the body. And the emotions move the human heart. And it was associated with the inner values that determine the ethical life. DongraeYaroo should ever criticize feudal era and values through the conflict with the changes in time. Through conflict with the realism tendencies and passions were melodramatic tendencies. DongraeYaroo is a folk masques of realism and melodramatic nature complex. DongraeYaroo has a part that is causing the conflict with the contents of the passion associated with the character's sexual desire is elsewhere. There are also distorted passions and inde normal expression of tragic passion passions that lead to death.

Web novels that are consumed on mobile devices are characterized by capturing one aspect of our society. The purpose of this study was to collect the keywords from web novels, to identify trends of web novels, and further to analyze the covert needs and characteristics of readers in connection with the existing researches. As a result of the analysis, novels with modern backgrounds and adult novels were popular in relation to easily readable and accessible mobile environment. Male characters tend to be ideally depicted in web novels. In contrast, characters with inner scars were popular among female characters. Although this study did not conduct an in-depth analysis of adult novels due to the limitation of web crawling, it is meaningful that this study analyzed modern people's inner needs and characteristics using the para-text like keywords in existing web novel studies that previously lacked quantitative analysis.
