본 연구에서는 한국어의 정서관련 어휘분석을 통하여 내적체계의 차원을 알아보고자 하였다. 이를 위해 연구1에서는 내적경험을 표현하는 데 자주 쓰이는 어휘들을 자유연상을 통해 100개를 선정하고 유사성과 빈도평가 자료를 다차원분석한 결과, 1차원(63%)은 불쾌, 2차원(25%)은 각성수준으로 해석될 수 있었고, 이는 기존의 차원모형의 주장과 거의 유사한 결과였다. 다른 이휘목록을 사용하였을 때의 결과와 비교하기 위해, 연구 2에서는 표정을 보고 정서를 추론하는 실험을 통해 자주 언급된 단어를 빈도순으로 22개 선정하였다. 이를 이용하여 같은 방법으로 다차원 분석한 결과 역시 같은 차원들이 얻어졌으나, 1차원의 비중이 훨씬 커서(89%)각성수준의 설명력은 (6%)상대적으로 작았다. 연구 3에서는 연구 1,2의 이휘목록이 전체 재적체계의 차원 공간에서 차지하는 상대적인 위치를 비교하기 위해, 두 어휘목록을 포함한 83개 내적체계의 단어를 차원평정시켜 분석하였고, 연구결과가 차원모형에서 갖는 시사점이 논의되었다.

The purposes of this study were to explore the relations of preschoolers' narrative representation profile types to diurnal cortisol regulation pattern at home. Fourteen story stems from the MacArthur Story Stem Battery (MSSB, Bretherton, et al., 1990) were administered to 40 preschoolers(22 boys, 18 girls, aged 5) recruited from 8 kindergartens in the Seoul and Gyeonggi areas. And also, their saliva cortisol was collected. The children's responses were aggregated into 5 dimensions, based on content themes and performance scores, which included emotions expressed and narrative coherence using the MacArthur Narrative Coding System(Robinson, et al., 2004). Data were analyzed by means of cluster analysis. Five response profiles emerged over the course of this research: Prosocial, Anxiety, Dyregulated aggression, Restricted, and Avoidance profiles. Cortisol at home showed decrease diurnal cortisol regulation patterns, however it showed a difference according to narrative response profiles. Restricted, Prosocial, and Avoidance profiles showed decrease diurnal cortisol regulation patterns. Anxiety profiles showed flat pattern, and Dyregulated aggression profile showed rising diurnal cortisol regulation pattern. These results show the preschoolers' internal representation may affect the diurnal cortisol reaction in daytime.

Subjects consisting of 335 middle school students were analyzed using arousal seeking tendency scales to determine the effect on student's scores on scales for physical education intrinsic motivation and physical education attitude. The data were subjected to frequency analysis, correlation analysis, reliability analysis, exploratory factor analysis, and multiple regression analysis as statistical methods. The results were as follows. In the subscales of arousal seeking tendency, novelty seeking positively influenced interest, efforts, and competence. In the subscales of arousal seeking tendency, novelty seeking positively influenced physical education attitude, but thrill seeking negatively influenced health and fitness only. In the subscales of physical education intrinsic motivation, interest and efforts positively influenced physical education attitude, while both competence and tension partly influenced it. These findings indicate that improving both attitude and intrinsic motivation of middle school students toward physical education would require a method of teaching and learning that encourages students′ novelty seeking in the subscales of arousal seeking tendency.

The purpose of this study was to identify the moderating effect of intrapersonal empowerment between subjective well-being and smartphone addiction. It was conducted to measure research variables from 242 university students. The moderating effect according to intrapersonal empowerment was analyzed through hierarchical regression analysis. As a result of analysis, first, there were significant relationship, among subjective well-being, intrapersonal empowerment, and smartphone addiction. Second, subjective well-being and intrapersonal empowerment had a significant negative effect on the smartphone addiction. Third, intrapersonal empowerment had moderating effect within the relationship of subjective well-being and smartphone addiction. In other words, the higher level of intrapersonal empowerment showed that subjective well-being more strongly negative effect on the smartphone addiction. Implications of these results were explored in relation to the importance of empowerment that could be taken to reduce smartphone addiction.

The purposes of the study is to examine the relationship between developmental assets, stress and risk behaviors of university students. The subject of the study is 1023 university students. Questionnaire organized by scales of developmental assets, stress and risk behaviors was used. The major findings were as follows; First, internal assets made direct effects on stress and risk behaviors. External assets made direct effects on stress. Second, mediating effects of stress were statistically significant in relations between developmental assets and risk behaviors. External assets were complete mediating effects by making effects indirectly on risk behaviors through the stress. Internal assets showed partial mediating effects.

Matching pursuit algorithm was successfully demonstrated useful in low bit-rate video coding, However, one of the practical concerns related to applying the matching pursuit algorithm to application is its massive computation required for finding bases whose weighted sum best approximates the given input image. The main contribution of this paper is that we provide a new method that can drastically reduce the computational load without any degradation of image quality. Its main idea is based on reducing the number of inner product calculation required for finding best bases because the complexity of matching pursuit algorithm is due to the exhaustive local inner product calculation. As the first step, we compute a matrix which is the 1-D inner product of the given motion-compensated error input image with the 1-D vertical Gabor functions using the separable property of Gabor bases. In the second step, we calculate length of each vector in the matrix that corresponds to 1-D horizontal Gabor function, and compare the length with the current maximum absolute inner product value so far. According to the result of this comparison, one can decide whether or not to calculate the inner product. Since most of them do not need to calculate the inner product value, one can significantly reduce the computational load. Experimental results show that proposed method reduces about 70% of inner product calculation compared to the Neff's fast algorithm without any degradation of image quality.

In this paper, focusing on definitions of terms related to ratio (a:b, external ratio, internal ratio, percentage, proportion, bi-ui-gap(value of a:b)), elementary school mathematics textbooks of Korea and Japan are compared. We can find significant differences between Korean and Japanese textbooks. In Korean textbook, 'bi-yul' includes both of the internal ratio and the external ratio. In Japanese textbooks, the external ratio(amount of unit size) and the internal ratio(wariai) are defined independently. And a:b is set to a subconcept of the internal ratio. In addition, a:b and percentage are presented as methods to express the internal ratio. From these results, the following four implications for developing our mathematics textbooks can be presented as conclusions. First, it is necessary to limit the ratio to mean the internal ratio. Second, it is necessary to define connotatively the ratio as the internal ratio and to set it as a prior concept of a:b. Third, it is necessary to define 1% as the internal ratio 0.01. Fourth, it is necessary to define bi-ui-gap as a number for expressing a:b, when viewing a:b as the expression method of the internal ratio.

Within a country, owing to the restriction of aggregate which have been supplied to construction sites, applicability of byproducts such as the copper slag is expected to be more reasonable. In this study, on the basis of characteristics, grain distribution and environmental stability of copper slag, its engineering application was estimated as the vertical and horizontal drainage material. As a results of laboratory tests, it was shown that the permeability of the copper slag was similar to that of sands under vertical drainage condition. In addition, the copper slag showed higher critical hydraulic gradient than that of sand under upward vertical flow state. The copper slag has potential safety against piping and it that the copper slag is suitable for drainage and filter material.

This paper introduces a recently developed thinning-out timber framed earth retaining wall system. Timber framed retaining walls are usually designed by using design code of gravity type retaining wall but internal stability of timber framed earth retaining walls is often neglected. In this study, it is recommended to use the design code for segmental retaining walls by National Concrete Masonry Association (NCMA, 1997) to check internal stability of timber framed earth retaining wall. Based on the several shear test results for 3 types of timber frames, a simple design chart including internal stability is suggested.
