Perceptions of beauty change and are shared with others in the media of emotional words. In the modern age, a mix of traditional and modern make-up cultures has changed the standards of beauty. Therefore, an analysis using emotional words (an image that consumers have for certain subjects) and an image scale that intuitively shows them can be an important means for understanding changes in the "beauty of the time". This paper considered changes in typical aesthetic characteristics that women pursued through make-up by analyzing emotional words in white make-up powder advertisement texts from the 1920s through the 1930s. Imported modern technologies changed cosmetic manufacturing techniques and advertising methods to create a momentum that changed women's make-up culture from light to heavy make-up or from white to color make-up. Such changes have led to changes in the perception of beauty and were expressed through sensitive vocabularies such as pure, new, fresh, lofty, lively, healthy, and cheery. Such changes reflect social aspects such as women's aspirations for high status, pursuit of security, or women's roles under the wartime regime to show a change from beauty with an attribute of [+cool] to that of [+soft].

Galvalume steel (GL) is widely used in marine and industrial environments. It is characterized by better corrosion resistance than carbon steel. However, corrosion and economic losses may occur as the usage time is increased. Therefore, in this study, an outdoor exposure test of GL for 36 months was conducted across six regions of Korea. Parameters such as corrosion rate, chrominance (color, chroma, and brightness), glossiness, and surface appearance were analyzed. The results showed no significant change in appearance, and the initial corrosion rate was large, but a tendency to decrease with time was observed. Increased outdoor exposure time led to increase in the level of corrosion products. In the case of coastal areas where S, Cl, and other elements were detected, a relatively high decrease in Zn content was observed. Al forms a protective oxide film and exists in the coating layer, but Zn dissolves due to its chemical activity and low potential.

During the COVID-19 pandemic, the obligatory wearing of masks has led to increased consumer demand and the diversification of mask design. Accordingly, it is necessary to understand the inner meaning and characteristics of masks in the pandemic situation. Therefore, the purpose of this research is to analyze the characteristics of fashionable masks and their new cultural meaning under the COVID-19 pandemic. This research is based on literature review and empirical research. Drawing on an investigation of the historical evolution of masks and their transition under the pandemic (exhibiting differences in mask culture among countries and regions), this study analyzed 54 distinctive fashion masks designed by fashion brands and influencers that appeared from January 2020 to January 2021. The characteristics of fashion masks identified under the influence of the pandemic are as follows: Message delivery on political issues and human rights; psychological defense and expression of individuality; and conspicuous display via luxurious materials and luxury brand logos; moreover, the design of the mask uses the same material, color, pattern, decoration, and other methods as clothing to achieve the overall style. Over the course of the pandemic (and even in post-pandemic lifestyle), fashion masks are becoming more diversified conveying new social and cultural meanings.

This case study developed and operated "Fashion & Film" as a fashion-related liberal arts course. The class was designed to include fashion styles exhibitted in films, fashion-related PPL, fashion design through film, fashion images of movie characters, considering gender & color images expressed in movie costumes, and the history of western costumes and asian folk costumes in films. The class was counducted through various teaching methods, such as lectures, student's presentation of movie plots, and team discussions, which created a student-led class. The team presentations at the end of the term were intended to enhance the understanding of fashion through movies. The results of subjective lecture evaluation of "Fashion & Film" showed the most satisfaction with the communication with professor. Students said that it was good to understand fashion through film. They expressed a burden with the team project; however, they were satisfied with the team project outcomes. Students said that PowerPoint was used very effectively. On the other hand, there was an prevelent opinion that the content of PowerPoint and workbook did not match. To address this inconvenience, a textbook called "Fashion in Film" was published and used in the first semester of 2020. The multiple-choice evaluation showed that students were generally satisfied with the "Fashion & Film" class.

Recently, protein-fortified milk powders are being widely consumed in Korea to prevent sarcopenia, and the demand for high-protein food powders is continuously increasing in the Korean market. However, spray-dried milk proteins have poor flowability and wettability owing to their fine particle sizes and high inter-particle cohesive forces. Fluidized bed agglomeration is widely used to improve the instant properties of food powders. This study investigated the effect of fluidized bed agglomeration on whey protein isolate (WPI)-fortified skim milk powder (SMP) at different SMP/WPI ratios. The fluidized bed process increased the particle size distribution, and agglomerated particles with grape-like structures were observed in the SEM images. As the size increased, the Carr index (CI) and Hausner ratio (HR) values of the agglomerated WPI-fortified SMP particles exhibited excellent flowability (CI: <15) and low cohesiveness (HR: <1.2). In addition, agglomerated WPI-fortified SMP particles exhibited the faster wetting time than the instant criterion (<20 s). As a result, the rheological and physical properties of the WPI-fortified SMP particles were effectively improved by fluidized bed agglomeration. However, the fluidized bed agglomeration process led to a slight change in the color properties. The CIE L^* decreased, and the CIE b^* increased because of the Maillard reaction. The apparent viscosity (η_a,10) and consistency index (K) values of the rehydrated solutions (60 g/180 mL water) increased with the increasing WPI ratio. These results may be useful for formulating protein-fortified milk powder with better instant properties.

Lairage, a part of the animal welfare practices, has been known to mitigate pre-slaughter stress in animals. However, research investigating the relationship between lairage and pork meat quality remains scarce. In this study, we conducted a comparative analysis of the physicochemical quality and storage stability of pork from pigs subjected to immediate slaughter (CON) and those provided with a 24 h lairage before slaughter (LRG) over a 7-day storage period. The loins from 20 castrated pigs in each group, respectively, were collected at 1, 3, 5, and 7 days and used for analysis of meat quality and storage stability, including pH, meat color, moisture, water holding capacity, drip loss, cooking loss, shear force, fatty acid composition, lipid oxidation, antioxidant activity, and electrical resistance. Overall, there were no significant differences in physicochemical meat quality parameters between CON and LRG groups. Similarly, no differences were observed in the storage stability of pork including 2-thiobarbituric acid reactive substances, 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity and electrical resistance. However, the proportion of unsaturated fatty acids was significantly higher in LRG compared to CON. In conclusion, 24 h lairage for castrated pigs had limited impact on meat quality and storage stability but led to an increase in the unsaturated fatty acid proportion.

As much time is being spent with the family at weekends by the development of leisure culture, many people have begun to enjoy camping in the field. While many people use pensions or camping cars, many families or groups of friends go on camping in the summer holiday season. Although the tent design in this country has gradually been developed, it is not as developed as overseas designs with unique design characteristics according to climate, cultural behavior and colors. In this research, the American and Korea tent designs are compared in terms of color and frame. The differences are analyzed and a direction for tent designs appropriate for Korea in terms of size, area, ease of carriage and installation is proposed through theoretical data and idea sketches. The frame weight has been minimized and the durability increased for the ease of carriage and installation. The style and number of windows have been increased in order to provide a comfortable space by understanding the influx of airflow and the size of the tent has also been increased to provide extra space for storage. The information on the overseas and domestic tent design trends led to a color comparison and the extraction of images of language. The tent based on the new design is currently being mass-produced in China following 3 months of preparation including sample making and testing.

Porcelain fused to metal crown has been used mostly over the last 50 years for restorations in dentistry. However, the patients' awareness of aesthetic aspect, biocompatibility and the problems such as an allergy to metals led to the growing interest in the 'metal free restoration'. In particular, the price of the precious metals that have been mainly used to date has risen drastically, which made them impossible to play their role as oral restorative materials anymore, and in addition, the PFM restoration has intrinsic problems of chipping and fracture. Therefore, the CAD/CAM has been drawing more attention than ever due to the popular needs for the material that is more aesthetic and stronger for restoration of the molar implant. Considerations in carrying out the full zirconia restoration are as follows: 1) strength, 2) combination work, 3) light penetrability, 4) treatment of cracks, 5) the color reproducibility of the block, 6) the abrasivity of antagonistic tooth, 7) low temperature degradation. In this presentation, the color reproducibility of the block will be discussed. One of the biggest reasons for avoiding the full zirconia restoration is that it is difficult to reproduce the natural color compared to the conventional PFM restoration. Thus, many clinicians show reluctance due to the exposure of the ugly block when the coloring on the surface is removed after occlusal adjustment. From the experience of using blocks by Zirkonzahn for more than 4 years, it is considered that these problems can be addressed to some degrees. Accordingly, how to make restorations that are well in harmony with surrounding prosthesis or natural teeth will be discussed.

TTI is a small label of which the color changes by time-temperature history during food storage. The food shelf life (SL) was compared with that of TTI, the time for TTI to reach the end-point of its color change, for the various discrepancies in two Arrhenius activation energies (Ea), an important parameter of temperature dependence. The SL of TTI and food were mathematically simulated, based on zero-order and first-order kinetics, respectively. In the case Ea of food was smaller than that of TTI, the SL of food was larger than that of TTI, meaning TTI reaches the end-point of color change earlier even though food is still fresh. In the case of Ea of food > Ea of TTI, the food reaches the SL earlier than the TTI. In addition, the magnitude of ${\Delta}Ea$ between food and TTI led to the bigger ${\Delta}SL$. To be safe, $SL_{Food}$ > $SL_{TTI}$ would be practical although $SL_{Food}{\fallingdotseq}SL_{TTI}$ is ideal.
