This study reviewed the Technology & Home Economics Education textbooks to examine if their illustrations would be appropriate for students' balanced view of gender. To this end, the textbooks of 'Technology & Home Economics Education 1 and 2' from 12 publishers (24 books in total) were analyzed focusing on the formative and content characteristics of illustrations in the textbooks. The results of this study is as follows. There were areas in the textbooks that may not be considered gender-equal. Although the textbooks have been improved to some extent from the previous versions, they still show gender stereotypes biased towards men. If students are constantly exposed to the prescriptive characteristics that are in favor of certain gender, they would find it difficult to develop their personality strengths, due to the gender role pressures. In order to help students cultivate sensitivity and activism toward the gender equality issues, it is important that the textbooks are gender-equal. To summarize, in order to suggest to students a balanced image of society with male and female cooperating with each other in diverse domains, it is deemed necessary to constantly examine and revise the textbooks for their gender stereotypic contents, and thereby, improve them for gender equality.

A chameleonic surface proposed in this study was a pin-art and 3D display device for generating arbitrary shapes. A smooth and continuous surface was formed using slim telescopic actuators and high-elasticity composite material. Realistic 3D shapes were continuously generated by projecting dynamic mapping images on the surface. A slim telescopic actuator was designed to show long strokes and minimize area for staking. A 3D shape was formed by thrusting and extruding the high-elasticity material using multiple telescopic actuators. This structure was advantageous for generating arbitrary continuous surface, projecting dynamic images and lightening weight. Because of real-time synchronization, a distributed controller based on EtherCAT was applied to operate hundreds of telescopic actuators smoothly. Integrated operating software consecutively generated realistic scenes by coordinating extruded shapes and projecting 3D image from multiple projectors. An opera content was optimized for the chameleon surface and showed to an audience in an actual concert.

Effect of the thickness of packaging film on the ripening of mature-green mume (Prunus mume Sieb. et Zucc) fruit was investigated by measuring physicochemical changes of the fruit during storage. Fruits were packaged using low density polyethylene (LDPE) films with thicknesses of 20, 30, and 40$\mu$m and stored at the room temperature. The physicochemical properties such as contents of various pectic substances, molecular weight distribution of soluble pectic substances, and surface image of the fruit were determined during storage of 8 days. In general, regardless of the thickness of the films applied, a content of water-soluble pectin (WSP) in the fruit was increased during storage, but both contents of HCI- soluble pectin (HSP), and Ca and Mg in total alcohol-insoluble solids were decreased. Sephacryl S-300 gel filtration study revealed that fractions of high molecular weight HSP and WSP decomposed into lower molecular weight pectins during storage. The scanning electronic microscope also identified a significant structural change of the fruit skin over the storage time. It could be concluded from the results that fruits packaged with LDPE 30${\mu}{\textrm}{m}$ film maintained the highest physicochemical quality of green mume fruit during storage.

This paper intends to examine the significance of the "Minjoong Misool(People's art)" of the 1980s emerged in Korea in its social, cultural, and art historical context. This paper also aims to provide an analysis of the meaning and form of the individual artist's works, which have been overlooked under the dominant discourse that has emphasized their political role as a collective group. In particular, this paper scrutinizes the work of "Critical Realists" by examining the way in which they perceived Korean society in the early 1980s and visualized their experiences of the period. The figurative art newly emerged in the early 1980s challenged the formalist Modernism, which was adopted into Korea and translated into monochrome paintings and the work of the conversative academicism of the 1970s. The figurative art encouraged a social communication and moreover it intended to criticize the conflicts in the political, economical, and social domains in Korea. The targets of its critique include the unavoidable results of the unprecedented development of economy, various social phenomena of the post-industrial society, and the growth of the commercialized kitsch culture. Along with Shin, Hak-chul's work that incorporates collage technique since the 1980s, the work of some members of "Reality and Utterance" and "Im- sul-nyun" exemplify their critical interests in disclosing the false dream of wealth and happiness by both referring to and drawing on the utopian fantasy manipulated and distributed by mass media and commercial advertisements. This paper pays particular attention to Nouvelle Figuration emerged in France and Europe during the 1960s, which is comparable to the new figurative art emerged in Korea during the 1980s. Nouvelle Figuration criticized the autonomy in art isolated itself from political and social reality after WWII, in particular the indifference of Informel and abstract art as well as American abstract art. Moreover it became rather politicized around May of 1968. Given that French Nouvelle Figuration was introduced in Korea in 1982 and made a significant contribution to the formation of figurative art in Korea, it should be noted that the new figurative art emerged in the 1980s in Korea cannot be categorized merely in relation to People's Art. This paper intends to critically redress the notion that People's art was formed in the particular political, economical, and cultural context of Korea independent of the contemporary artistic practices outside Korea. It will provide a critical examination and analysis of the content and form of the new figurative art, from which People's Art was germinated, in the global context.

Melanin is synthesized by the melanocytes in basal layer of epidermis and distributed over all the layers of skin including corneocytes in stratum corneum, outermost layer of the epidermis. Melanin of corneocytes was stained using Fontana-Masson method and quantified by image analysis. The correlation between melanin contents and skin color value was estimated in the skin of 71 Korean women. Melanin covering area (MCA) showed good correlation with $L^*$ value and $ITA^{\circ}$ (Individual Typology Angle) (r = 0.6049, 0.6651, respectively). MCA can be used as new parameter for skin color study and has potential application for evaluating the efficacy of the skin whitening cosmetics.

The aim of this study was to investigate the physical properties of visible light curing Glass Ionomer cement for restorative esthetic filling. The control group was the autopolymerizing GC Fuji II Glass Ionomer cement (2.2: 1 P/L ratio) and the experimental groups were made by following procedure. To induce the polymerization by visible light, the powder of GC Fuji II GI cement and the liquid of Vitrabond for base & liner were mixed in an amalgam capsule with 2.5:1, 3.0:1, 3.5:1 P/L ratio (% wt/wt). After fabrication of specimens, compressive strength, fracture toughness ($K_{IC}$) Scanning Electron Microscope and X-ray Diffraction, water-leachable content, marginal leakage and surface roughness were studied. The results were as follows: 1. Only experimental No. 1 group (visible light curing) showed less compressive strength than control group 1 hour after curing. Strength was increased with aging in all groups, so the compressive strength of light curing groups was no less than that of autopolymerizing group after 3 weeks. 2. Experimental No.3 group (visible light curing) was inferior to No.2 group (visible light curing) in fracture resistance but light curing groups were more resistant to fracture than autopolymerizing group and showed ductile fracture pattern as compared with the brittle fracture pattern of autopolymerizing group. 3. From scanning electron microscopic image, various sized unreacted powder particles, surrounded by silica gel, were embedded in polysalt matrix. Light curing groups showed little crack and more dense unreacted particles than autopolymerizing group. 4. From X-ray diffraction analysis, GC Fuji II Glass Ionomer cement powder and all groups showed glassy appearance but light curing groups seemed to be more intensive in crystaline than autopolymerizing group. S. The most significant dissolution was shown in early setting period in all group. Light curing groups were dissolved less than autopolymerizing group. 6. Marginal leakage was not different significantly in case of cavity margin composed of same tooth structure (ex. only enamel margin, only dentin margin) but much more leakage was shown in dentin/cementum margin than enamel margin. In only case of only enamel margin, light curing groups were superior to autopolymerizing group. 7. All groups showed relatively smooth surface, which irregularity was less than $1{\mu}m$. Light curing groups were smoother than autopolymerizing group.

The purpose of this study was to investigate the effect of thermal treatments, such as a sous-vide and a conventional hot water cooking, on the texture changes of soybean sprout. A novel method to measure texture properties of soybean sprout have been determined because of the irregular geometry of soybean sprout. The shape of cotyledon of bean spout was accurately analyzed using an image processing and a geometry model. To minimize the effect of the contact area on the texture measurement, a blade type of probe was selected for the measurement. True stress was evaluated to reflect the shape changes during deformation, and demonstrated that the measurement accurately distinguished the effect of thermal treatment on the texture. Different heating time (i.e., 0, 10, 20, and 30 min) was applied for both sous-vide and conventional cooking. Thermal processing caused hardening of textures for both cotyledon and hypocotyl of soybean sprout. The conventional cooking method showed higher stress values than those of sous-vide cooking. Sprouts cooked by sous-vide released the moisture after thermal processing while sprout cooked by a conventional water bath method could hold the moisture content during thermal processing. The soybean sprouts treated by conventional cooking method showed a higher score in sensory evaluation.

Some artists and scientists in physics and animation originating from research on its form of expression thanks to the rapid development of the example in the late 20th century image production technology integrating existing media feature, perform a re-creation and pop culture content has been recognized as a key factor. animation of the modern emphasis is also commercial and artistic activities as show whether the artist can not be excluded that also target audience. The audience does not want only to receive offers simply 'seeing' and 'hearing' in the animation requires a more indirect mental met. the other side, the director should lead the audience to immerse myself in work as intended mystification induce the world. where a conflict occurs between the audience and the director and The director needs to have its troubleshooting point to 'Technology of the communication'. Which is reduced to 'How will tell,' is technology communication technologies that are abbreviated representations of animation director is accessible to the audience and it is a close relationship between the psychological aspect of audience. Because, the audience is reproduced in a limited space, but he called on the board of directors and the same time the screen, the audience located at reception and the director located at provide. It is given. led force is given to the director. for this reason, The director needs to pay attention to the psychological aspect of audience this can be explained based on psychoanalytic theory. In this paper, "How can you lie to the audience and the director is the same line?" put down logic that is the animation audience under the logic that takes place visually capture phenomenon "selective attention" and sub-concept of "goal-directed selection' and 'stimulus-driven capturel' for theory of psychology. also, Induction device to elicit selective attention of the audience accordingly, let's consider whether and how they apply in animation.

The purpose of this study was to investigate the effects of estrogen deficiency on pulpodentinal complex of tooth in ovariectomized rats. Thirty female Sprague-Dawley rats, 10 weeks old, were used. Rats were grouped into two groups. One group (n = 15) was subjected to sham surgery (SHAM) and the other group (n = 15) was ovariectomized bilaterally (OVX). Animals were sacrificed 12 weeks later, and their mandibular molars and associated periodontal supporting tissues were dissected out, and fixed in $10\%$ buffered formalin. For comparison of groups, immunostained for osteonectin. Histomorphometrical measurement of change of teeth was performed using an image analysis system and paired t-test was used and the level of significance for overall differences was set at p < 0.05. In immunostaining of osteonectin, they were significantly different from each other. The predentin thickness in OVX rats was wider than in SHAM rats. And in SHAM rats, osteonectin was more specifically stained in predentin areas than in OVX rats. These results indicate that estrogen deficiency increased the unmineralized predentin areas and decreased osteonectin content in pulpal tissues in rats. If our result is applicable to human studies, odotoblast is affected by estrogen deficiency.
