Cracks in reinforced concrete structures reduce overall durability by allowing the penetration of water and aggressive agents, thereby accelerating the deterioration of the reinforcing steel. Highway pavement and bridge decks are especially susceptible to this type of deterioration since these structures exhibit high rates of shrinkage and are frequently exposed to aggressive environmental conditions. The objectives of this investigation included the development of experimental procedures for assessing shrinkage cracking potential of recycled aggregate concrete, the evaluation of mix composition on shrinkage cracking potential, and the development of theoretical models to simulate early-age cracking behavior. Specifically, the influences of shrinkage-reducing admixture(SRA) and recycled aggregate concrete were investigated. The shrinkage-reducing admixture substantially reduces free shrinkage and restrains shrinkage cracking while providing similar mechanical properties. A fracture mechanics modeling approach was developed to predict the behavior of a variety of restrained concrete specimens. This modeling approach was used to successfully explain experimental results from a variety of mixture compositions. The model was used to demonstrate the influence of material and structural properties on the potential for cracking.

Invasive micropapillary carcinoma (IMPC) of the breast is recently described rare variant of invasive ductal carcinoma. This variant has a distinctive histological features and aggressive biological behavior. We reviewed the cytologic features of eight cases of IMPC. The cytologic smears showed moderate to high cellularity and the tumor tissue was composed of atypical, angulated, cohesive clusters of neoplastic cells with a papillary to tubuloalveolar architecture, and a morular growth pattern without fibrovascular cores was seen on the histopathology. IMPC of the breast has distinctive cytologic features and it is important to make an early diagnosis via fine needle aspiration cytology due to this tumor's aggressive behavior.

The purpose of this study was to review the importance of authoritative parenting for children's social adjustment. From the review it was suggested that the importance of authoritative parenting might be different according to the cultural contexts, which are Western and Asian cultures, and aggressive and social withdrawal behaviors. From the comparative cultural viewpoint, authoritarian parenting is not considered negatively by Asian parents, comparing with Western parents. Therefore the assumption that authoritative parenting has universal positiveness and authoritarian parenting has universal negativeness should be reconsidered. Regardless of cultures, children's aggressive behavior was related to the authoritarian parenting positively. But, in Asia, especially in China, the social withdrawal did not show at least negative relation with authoritative parenting. And it was reported that the authoritarian parenting could contribute to the change of inhibited behavior and enhancing the social adjustment. In addition, some implications were suggested for future researches about the relation between children's social adjustment and child rearing practices. Though this literature review was not exclusively based on the empirical studies, it would be valuable for reconsidering the perspective of Korean developmentalists interested in the relation between parenting and children's development in Korean culture.

The purpose of this research was to develop an scale to measure mathematics anxiety coping behavior of elementary school children. Of the first 45 items selected from a review of literature, 33 items were selected by content validation, modification and revision. Validity, reliability, and item discrimination was based in responses of 1,831 subjects. Data were analyzed by factor analysis, correlation, Cronbach's, $\alpha$, mean, standard deviation, percentages, and t-test. The resulting Scale of Children's Mathematics Anxiety Coping Behavior consisted of 26 items with 5 factors : active problem-solving, aggressive emotion expression, aversive coping, passive coping, and seeking social support. Cronbach's $\alpha$ ranged from .67 to .86 for five factors. T-test showed the 26 items of the scale to be discriminant.

Maternal beliefs about preschoolers' displays of aggression and social withdrawal and the extent to which their strategies for dealing with these behaviors can be predicted from beliefs were examined. And the extent to which maternal childrearing behavior and preschoolers' social problematic behaviors can be predicted from beliefs. 202 mothers of 5-year-old(114 boys; 88 girls) were presented with descriptions of hypothetical incidents of peer-directed aggression and social withdrawal. Maternal beliefs were different according to kinds of problematic behaviors. Thus most mothers attributed preschoolers' aggression to situational factors, social withdrawal to disposition. Mothers felt embarrassed about aggression and concerned about social withdrawal. The power assertive strategies were more used for dealing with aggression than social withdrawal. The choice of strategies for dealing with these behaviors and maternal childrearing behavior were related to maternal beliefs. Also preschoolers' social problematic behaviors were effected from maternal beliefs and childrearing behavior.

The main purposes of this study is to evaluate clothing behaviors according to cosmetic surgery parts and to research how the clothing style preference is expressed depending on each clothing behavior group. This study focuses on women in their 20s and 30s living in Seoul and Gyeonggi area whom have cosmetic surgery experiences. From the women being evaluated, the following groups are divided and then surveyed with equal frequency and ratio: 'facial surgery', 'face contour surgery', 'breast surgery', and 'body figure revision'. When comparing the changes in clothing style preferences before and after the cosmetic surgery, they prefer silhouettes which show body shapes, diversity of color tones, and more overall exposing preferences. After investigating the preferred clothing styles based on cosmetic surgery parts, it is being analyzed that body exposure is more aggressively expressed upon after taking the surgery because the self satisfaction is increased according to the changes in their body shapes after the surgery. Lastly, after looking into the cosmetic surgery and the clothing preferences styles of each clothing behavior group, there seems to be more breast surgeries and body figure revisions for aggressive and extroverted characters: the sex-appeal and mood switching type. It is also being analyzed that facial surgeries are more common in the passive group: information collection, trend alignment, and beauty preference. Such results are also reflected in clothing preferences styles: the biggest change is shown in the aggressive and extroverted group, the sex-appeal types.
