The aims of this study are to develop a STEAM program focused on the appearances of birds' beaks and insectivorous plants and to identify its influence on elementary students' basic scientific process skills, creative problem solving ability and affective domain. For these objectives, the STEAM program was developed by reorganizing contents of the appearances of animals and plants in the units of 'Life of Animals' and 'Life of Plants' from 2009 revised national science curriculum for 3th and 4th grades. The developed STEAM program was applied to twenty nine 3th grade students of J elementary school located in S city. As a result of applying the STEAM program, the experimental group in this study showed significant improvements of the creative problem solving ability, scientific process skills and affective domain compared to the control group's scores. Therefore, development studies on STEAM programs integrated different science fields using animals and plants could be meaningful works to encourage elementary students' skills and interest.

This paper proposes an automatic method for generating and 3D draping the skirt 3D models. The method constructs a 3D basic model of the skirts using elliptic cylinder and generates the various skirt 3D models by controlling the ellipses of the basic model. B-Spline approximates the wrinkles around the ellipse for the various 3D draping changing according to designs and textiles. We make some real skirts and investigate appearances for their drapes. This paper simulates their appearances and obtains good results. Furthermore, adaptation of the skirt 3D model to a personal character implements realistic coordination of the various skirts.

The corelation between surface tensions and surface appearances of SK O5a opaque glazes for earthen wares were investigated. The surface tension values were theoretically calculated by using Dietzel's factors of constituent oxides of glaze. The surface appearances of glazes, especially the pinhole phenomena were strongly effected by the surface tension values showing the following general tendencies: (1) In the range of 305±3 dynes/cm of surface tensions, glazes showed almost no pjnholes. (2) In the range of surface tensions less than 300 dynes/cm, the large numbers of small pinholes or eggshell textures were observed. (3) In the range of surface tensions higher than 310 dynes/cm, large and deep pinholes were observed. (4) The contact angles of glazes on the wall tile body substrate are in the good proportional agreement with the surface tension values calculated by Dietzel's factors.

This study was written in order to help understanding of visible diagnosis of spirit(神). Visible diagnosis of spirit(神) is a very important factor of diagnosis and a first step of visible diagnosis. Spirit(神) is closely connection with appearance(形), so is revealed by appearance(형). If we make a visible diagnosis of spirit(神), we know the prosperousness of energy and the relative seriousness of an illness. Spirit(神) is understood by appearances and movements of patient, and influenced by seasons, lands, human's relationship and the grade of age. Visible diagnosis of spirit(神) is practiced by the observation of movements, appearances, languages, voices, mental condition, color, eye, etc. By visible diagnosis of spirit(神), we can conclude existence or nonexistence of spirit(神), discriminate true spirit(神) from false spirit(神), and diagnose mental diseases. As comparing spirit(神) with appearance(形), we can decide good or bad prognoses.

Tween refers 'between' generation aged of 10-16 who are between child and high teens. Tweens have been regarded as one of the fast growing markets and they show some unique characteristics as next-generation consumers. This study has explored the perception of their appearances and clothing styles, style preferences, and influencing factors on clothing behavior of tweens. 120 students aged of 12-15 participated in depth interview and data were structured and categorized by applying domain analysis. Results showed tweens have great concerns on their appearances and styles, so they want to express their identities and aesthetic favors through clothing styles. As for clothing style preferences, they have multi-facet tastes such as casual, active, feminine/ masculine, sophisticated, dramatic, etc. Factors influencing on their clothing behavior include reference groups like friends, dual desires of conformity and individuality, fashion, and brand names.

Common radiographic appearances of ossifying fibroma (OF) are well demarcated margin, radiolucent or mixed lesion. Lesions for the radiographic differential diagnosis with OF include fibrous dysplasia, focal cemento-osseous dysplasia. Other confusing lesions might be the mixed lesions such as calcifying odontogenic cyst, adenomatoid odontogenic tumor, calcifying epithelial odontogenic tumor, and benign cementoblastoma. We reported three cases of OF in posterior mandible. These cases showed a little distinguished radiographic features of OF and diagnosed from a combination of clinical, radiographic, and histopathologic information. We need to further refine radiographic and histopathological features of OF and other confusing lesions with literatures review because some cases of these lesions are not easily differentiated radiographically and histopathologically.

The human facial appearances vary globally and locally according to identity, pose, illumination, and expression variations. In this paper, we propose a hybrid-nonsmooth nonnegative matrix factorization (hybrid-nsNMF) based appearance model to represent various facial appearances which vary globally and locally. Instead of using single smooth matrix in nsNMF, we used two different smooth matrixes and combine them to extract global and local basis at the same time.

This paper proposes a geometrical method for generating and draping the skirt 3D models. The method constructs a 3D basic skirt model using a truncated elliptical cone and generates the various skirt 3D models by controlling the elliptical cone. The B-Spline approximates the 3D drapes which change variously according to the angles and the textiles of the skirts. The mapping sources consist of the textile textures and the skirt 2D model. The 2D models are obtained by mapping the 3D skirt models to the 2D plane. The mapping sources allow us to map the textiles to the 3D skirts. We make the real skirts for the 6 kinds of angles and textiles. and investigate the data of their drape appearances. The investigated data are applied to the virtual skirts. Appearances of the virtual skirts are similar to those of the real.

The research is a correlational study to look for causes and factors relating to the design of written documents (professional reading materials) and identify those relationships that are useful for communication designers. The research specifically targeted the relationships between perception and reader's past experiences and appearance of the written documents. A preliminary survey, such as interviews, discussions, questionnaires and brainstorming sessions are conducted to establish the observable attributes related to perception which are reader's interests, importance of information and written documents complexity. Finally, the research used Structural Equation Model (SEM) to identify significant differences and analyze strong and weak correlations between these attributes. In general, the results of the study shows that the attribute appearances of a written documents with excellent visualizations for information display shows a strong correlation with interests while the attributes importance is weakly correlated with the complexity of the documents.

A female reticulated giraffe (Giraffa camelopardalis), 20-month-old, 342 kg, died at Seoul Zoo on January 2, 2009 after a stressful episode of chronic diarrhea. Given the appearances postmortem, it was strongly suspected that the giraffe suffered from malnutrition for a long time. Typical appearances of serous fat atrophy were shown on most fat tissues of body organs such as heart, bone, liver, mesentery and kidney. In this study, the sudden death that had been known as "peracute mortality syndrome" was clearly identified to have resulted from a lack of understanding the Browser's diet and general failure in giraffe husbandry. Individualized care and high quality hay must be provided to compensate higher consumption of metabolic energy and to prevent animal loss in winter season.
