본 논문에서는 메쉬 구조의 다중처리시스템을 위한 새로운 할당방법을 제안한다. 이 할당방법은 다른 가용 서브메쉬와 중첩되지 않는 독립 가용 서브메쉬를 유형에 따라 분류하여 유형별 가용 서브메쉬 리스트를 생성한다. 그리고 태스크의 유형에 따라 해당 유형별 가용 서브메쉬 리스트에서 최적할당이 가능한 서브메쉬를 찾음으로써 서브메쉬를 탐색하는데 소요되는 시간을 줄인다. 이 때 서브메쉬를 찾지 못하면 확장지수를 이용하여 더 큰 가용 서브메쉬를 형성한 후 할당함으로써 태스크의 대기 시간을 줄이고, 이 결과로 외적단편화를 줄이는 효과도 얻는다. 또한 할당 해제시 독립 가용 서브메쉬는 다른 가용 서브메쉬의 크기 에 변화를 주지 않기 때문에 그 유형에 따라 유형별 가용 서브메쉬 리스트에 삽입한다. 그럼으로써 할당 해제 후 유형별 가용 서브메쉬 리스트를 재생성하기 위해 전체 메쉬 구조를 탐색 할 필요가 없어진다.

Size/scale is a central idea in the science curriculum, providing explanations for various phenomena. However, few studies have been conducted to explore student understanding of this concept and to suggest instructional approaches in scientific contexts. In contrast, there have been more studies in mathematics, regarding the use of number lines to relate the nature of numbers to operation and representation of magnitude. In order to better understand variations in student conceptions of size/scale in scientific contexts and explain learning difficulties including alternative conceptions, this study suggests an approach that links mathematics with the analysis of student conceptions of size/scale, i.e. the analysis of mathematical structure and reasoning for a number line. In addition, data ranging from high school to college students facilitate the interpretation of conceptual complexity in terms of mathematical development of a number line. In this sense, findings from this study better explain the following by mathematical reasoning: (1) varied student conceptions, (2) key aspects of each conception, and (3) potential cognitive dimensions interpreting the size/scale concepts. Results of this study help us to understand the troublesomeness of learning size/scale and provide a direction for developing curriculum and instruction for better understanding.

This study was performed to compare the size of soft palate, tongue and airway according to the types of the malocclusion and evaluate the correlation between the size of soft palate, tongue, airway and dentofacial skeleton respectively. The sample of this study was 98 malocclusion female patients between the ages 12 and 17 years. The lateral cephalometric radiographs were taken and the distance, angle, ratio and area of the dentofacial skeleton, soft palate, tongue and airway were measured and evaluated statistically. The results obtained were as follows: 1. There was significant difference in SNB, ANB, facial angle, facial convexity, A-B plane angel, Y axis to FH, SN-MP, Wits appraisal, ODI and APDI according to the types of malocclusion. 2. The hyoid bone was more posteriorly positioned in Class II malocclusion group than other two groups and superio-inferior position of the hyoid bone was not different according to the malocclusion types. 3. The nasopharyngeal area of Class II and Class III malocclusion group was smaller than that of Class I malocclusion group, and the pharyngeal area of Class II malocclusion group was smaller than that of Class I and Class III maocclusion group. There was no difference of the area of the soft palate, tongue, oropharynx and hypopharynx according to malocclusion types. 4. The ramal height and mandibular body length(Go-Me) showed positive correlation with the area of tongue, nasopharynx, oropharynx, and pharynx. SNA did not correlated with the area of tongue and airway but SNB showed positive correlation with the area of hypopharynx and pharynx. The anterior, posterior facial height, upper and lower central incisor position to facial plane showed positive correlation with tongue area.

The purpose of this meta-analysis was to address two questions: (1) To what extent are types of child abuse related to psycho-social maladjustment of the abused? (2) Do relations found in this study vary by the gender, sample size, year of publication, types of publication, and respondents' age? The materials of this study were based on 14 variables obtained from 104 published and unpublished (doctoral disserations and master's theses) research papers over a span of 26 years(1990-2016). Child abuse related variables were categorized into physical abuse, emotional abuse, neglect, and abuse while psycho-social maladjustment grouped as internal (anxiety, depression, withdrawal, and anxiety/depression) and external problem behaviors(aggression, problem behavior, and delinquency). Major findings were: Medium effect size of emotional abuse, abuse, physical abuse, neglect on psycho-social maladjustment among the abused were calculated. Emotional abuse was highly related to every internal and external problem behaviors. Neglect was found to have higher effect size in external problem behaviors than internal problem behaviors. Publication types moderated the association between types of child abuse and internalization while year of publication, number of samples and publication types showed moderation effects on the relation between types of child abuse and externalization. Finding suggest that future studies on child sexual abuse and those on intervention outcome are required and use of well validated instruments are essential.

The purpose of this study is to analyze the variation in pupil size as shown in the scientific hypothesis generation process of students in Elementary School. The subjects for research consisted of 20 fifth-year students at Seoul B elementary school who agreed to participate in the research. The task consisted of four scientific hypothesis-generating tasks. SMI's Eye Tracker(iView $X^{TM}$ RED) was used to collect eye movement data. Experiment 3.6 and BeGaze 3.6 softwares were used to plan experiment and analyzed the task performance process and eye movement data. The findings of this study are twofold. First, there were four types that generate hypothesis about the tasks. Second, in the moment of generating hypothesis, participants' pupils have grown bigger. And while thinking of generating hypothesis or elaborating hypothesis, there were no big changes. These results show the moment of generating hypothesis is affected by emotional factors besides cognitive factors.

In the 2000s, character animation technique is used at domestic TV character animation ads of diverse items displaying new character patterns and expression techniques of a high level. This study intends to identify the characteristics of TV character animation ads based ell character aesthetic theory and advertising rhetoric theory, and based on these findings, analyze trend and stream of expression in TV character animation ads by examining and classifying advertisements released in the past four years by items, character patterns and expression techniques. The results showed that TV character animation ads have been concentrated on confectionery, beverages and foods in the past, but the items have been diversified through the years. With reference to character patterns, personal and animal characters had made the main pattern, but recently product, virtual and composite characters are on the increase. In expression techniques, cell animation technique was found to be the most frequently used technique, which was followed by full-3D, cell and live action, cell and 3D and the clay animation technique. A trend like this suggests that TV character animation advertising items will continue to increase in line with the participation level of targets. In the meantime, personal and animal characters will continue to make the leading character pattern, while virtual and composite character patterns emerge in new forms. In expression techniques, live action combined with 30 technique and techniques using new expression materials will appear with cell animation technique as a central figure. As a whole, Korean character animation advertisement is expected to keep on growing to a new dimension in the aspect of items, character patterns and expression technique.

The purpose of this study is to examine the influence of variable cash compensation depending on short-term performances instead of stock compensation for the executives on the investment in tangible assets, investment and R&D, and profit reconciliation. The detailed objectives of the study include, first, to examine the influence of the cash compensation on investment in tangible assets and profit reconciliation depending on the characteristics of the company and, second, to examine the influence of cash compensation on the profit reconciliation of the investment in R&D depending on the characteristics of the company. The results of the analysis in this study can be summarized as follows; Firstly, the result of the positive analysis, as the compensation for the executives increased, by the characteristics of the companies conducted on the significant 'positive' (+) on the investment in R&D and the profits reconciliation showed that the high tech industry and the share ratio of the executives did not show a significant result, while the debt ratio showed a significantly positive result. Secondly, the result of the positive analysis, as the compensation for the executives increased, by the characteristics of the companieson the significant 'positive' (+) of the investment in tangible assets and reconciliation of profits showed that the high-tech industry did not show a significant result, while the hypothesis on the share ratio of the executives and the hypothesis on the debt ratio showed results that are significantly positive as expected. In other words, it can help Korean companies, which have to investment in R&D and tangible assets to increase their competitiveness and promote future growth dynamics, to design a manager compensation system that is appropriate for our country to support efficient investment decision-making.
