Objective: The purpose of this study was i) to identify the characteristics of carcass traits in Chikso by gender, region, age at slaughter, and coat color using the carcass data collected from the nationwide pedigree information and coat color investigation, and ii) to estimate genetic parameters for breed improvement. Methods: A linear model was used to analyze the environmental effects on the carcass traits and to estimate genetic parameters. Analysis of variance was performed using TYPE III sum of squares for the unbalanced data provided by the general linear model procedure. Variance components for genetic parameters was estimated using REMLF90 of the BLUPF90 family programs. Results: Phenotypic performance of carcass weight (CW), eye muscle area (EMA), and backfat thickness (BF) in Chikso were lower than those of Hanwoo. This is a natural outcome because Hanwoo have undergone significant efforts for improvement at the national level, a phenomenon not observed in Chikso. Another factor influencing the above outcome was the smaller population size of Chikso compared to that of Hanwoo's. The heritabilities of CW, EMA, BF, and marbling score in Chikso were estimated as 0.50, 0.37, 0.35, and 0.53, respectively, which were was higher than those of Hanwoo. Conclusion: Based on the genetic parameters that were estimated in this study, it is expected that the carcass traits will improve when the livestock research institutes at each province conduct small-scale performance tests and the semen is provided to farmers after selecting proven bulls using the state-of-art selection technique such as genomic selection.

The speed of the reformation of the Korean engineering and science education systems is very slow compared with the fast change of the society. Current society requires colleges to raise high quality gold color engineers, who can feed tens of thousands people, however current education system cannot fulfill the requirement. So we need a novel education system to adapt the fast change of the society. In this study, we analyzed the difference of the education quality between supplies and demands, and based on the analysis, we suggested a new continuous quality improving system. We also collected current data on the student capability of Korean engineering freshmen and surveyed on the required vocational basic skills. Finally we suggested some programs with that the government could support improving the quality of engineering and science college students.

Recently, various contents using human motion are developed in computer vision and game industries. If we try to apply human motion to application programs and contents, users can experience a sense of immersion getting into it so that the users feel a high level of satisfaction from the contents. In this research, we analyze human head motion using images captured from an webcam and then we apply the result of motion recognition to a game without special devices as an interface. The proposed method, first, segments human head region using an image composed of MHI(Motion History Image) and the result of skin color detection, and then we calculate the direction and distance by the MHI sequence. In experiments, the proposed method for human head motion recognition was tested for controlling a game player. From the experimental results we proved that the proposed method can make a gammer feel more immersed into the game. Furthermore, we expect the proposed method can be an interface of a serious game for medical or rehabilitation purposes.

Objective: Detection of adulteration in processed meats is an important issue for some countries due to substitution of beef with a cheaper source of protein like poultry. In this study, the presence of chicken meat was investigated using real-time polymerase chain reaction (real-time PCR) and enzyme-linked immunosorbent assay (ELISA) techniques to verify adulteration of fermented sausage samples. Methods: A total of 60 commercial samples were collected from 20 establishments in three replicates including 10 fermented sausage manufacturers and 10 butchers to investigate the presence of chicken meat with the sequential use of real-time PCR and ELISA techniques. In addition, pH, moisture content, water activity and color values of the samples were determined. Results: Both real-time PCR and ELISA showed agreement on the presence or absence of chicken meat in 55 out of 60 fermented sausage samples and chicken meat was identified with both methods in 16 samples. Five samples produced inconsistent results for the presence of chicken meat in the first run. Nevertheless, the presence of chicken meat was verified with both methods when these samples were analyzed for the second time. In addition, the average physico-chemical values of the fermented sausage samples tested positive for chicken meat were not significantly different from some of those fermented sausage samples tested negative for the chicken meat. Conclusion: The sequential use of real-time PCR and ELISA techniques in fermented sausages could be beneficial for the government testing programs to eliminate false negatives for detection of adulteration with chicken meat. Furthermore, consumers should not rely on some of the quality cues including color to predict the adulteration of fermented sausages with chicken meat since there were no statistical differences among some of the samples tested positive and negative for chicken meat.

Our research participants were composed of health teachers exhausted by the COVID-19 pandemic. This study analyzed the attitudes towards image-making through utilizing the job training at Gwangju Metropolitan Office of Education on August 2022, where our study was able to obtain and analyze 30 elementary, middle, and high school health teachers who participated. Image making is defined as playing a role in increasing self-esteem through outward appearances such as facial expressions and posture, personal color, makeup, tone, hairstyling, and fashion and impacting individuals inwardly to increase self-confidence. Therefore, there is a positive impact in providing an image-making program that considers the occupational characteristics of a health teacher. It had the effect of stress relief and aided in building a healthier self-image among the participants. The results our study showed the following results. First, all participants had various concerns regarding their appearance and deemed that image-making was necessary, yet they needed to be more informed regarding the specific methods of doing so. Secondly, participants were mainly focused on purchasing makeup products for image making. Although participants showed interest in a personal color diagnosis, there needed to be more support in approaching the subject as the diagnosis was necessary from an expert. Third, participants stated that image-making should occur for their middle-aged selves when experienced in the field. Participants believed that they would be more concerned with how others viewed them after gaining expertise. Hence, this study found that the occupational characteristics of health teachers greatly benefitted from image-making programs oriented to their careers and would also show an increase in job satisfaction.

This study was conducted to examine the association between the myosin heavy chain 3 (MYH3) in 6-bp deletion variant genotypes and meat color traits in a crossbred pig population Landrace and Jeju native black pigs (JNBP). The longissimus dorsi, semimembranosus, triceps brachii and biceps femoris muscle from each carcass were used for the analysis of meat color traits. A total of 187 pigs and three meat color traits, CIE L^* (lightness), CIE a^* (redness), and CIE b^* (yellowness), were analyzed. All experimental pigs were successfully genotyped for the MYH3 6-bp deletion variant using Polymerase chain reaction (PCR) analysis. We detected three MYH3 6-bp deletion variant genotypes qq, Qq, and QQ with 0.091, 0.551 and 0.358 genotype frequencies, respectively. Compared to qq homozygotes, the MYH3 6-bp deletion QQ genotype animals showed a higher levels of the meat colors traits CIE L^* (lightness), CIE a^* (redness), and CIE b^* (yellowness) in longissimus dorsi (p>0.05, p<0.001, p<0.001), semimembranosus (p>0.05, p<0.001, p<0.001), triceps brachii (p<0.001, p<0.001, p<0.001), and biceps femoris (p<0.01, p<0.001, p<0.001), respectively. The QQ genotype pigs was associated with increasing meat color traits in the crossbred between Landrace and JNBP. Our findings suggest that the MYH3 6-bp deletion variant genotypes can be used as valuable genetic markers for JNBP-related breeding programs to improve meat quality and control meat color traits.

Today, in the field of contemporary fashion design, AI is being actively utilized as a new design tool, leading to a new paradigm of collaboration between designers and AI. This study is about a method for developing integrated fashion design through collaboration between human designers and AI. The purpose of this study is to analyze the visual and formative characteristics and changes of fashion design images generated using the AI generation program Midjourney, thereby expanding the understanding and utilization methods of AI image generation programs in fashion design development. The results of this study are as follows. First, Midjourney has the characteristic of relying more on the characteristics of the existing image used rather than the command when creating the image. It also creates new images by distributing and applying the design through an eclectic interaction between the costume and the image background. By excluding the names of fashion items from the commands, you can generate images that can give you more diverse ideas. Second, Midjourney initially expressed clothing colors using colors used in fashion schematics in color creation, and gradually expanded to various color series. Third, there is a kind of compromise between color and design when Midjourney creates an image, and accordingly, by specifying and limiting the image background and clothing colors, more diverse and advanced fashion design images can be created.

This paper developed motifs through the use of images of masks with which the Korean innate consciousness of aesthetics is expressed. The motifs were applied to fashion items. This paper investigated the concept, origin and types of traditional masks through the existing literature. Using the computer graphic programs of Illustrator and Photoshop CS2, three basic motifs were set from the images of the nobleman, Bune of Hahoi Tal and Byeongsan Tal. Each motif was extended into two motifs by changing shape and color. For the basic motif design, this study sought to express contemporary images, suitably for each fashion item, while maintaining the basic shape of the masks and their traditional images. In addition, this study set the concept of the design so that could be accepted by various age groups. For the design of handkerchiefs, a rotating array, involving enlargement, reduction, repetition, and the gradation of motifs, as well as a diagonal symmetric array, and all-over patterns were developed. The T-shirt design created here was divided into a half-sleeve box type, a round neckline sleeveless type, a V-neckline close-fitting sleeveless type, and a V-neckline close-fitting cap sleeve type. For the design of necklaces, OLED or LED, which are considered as a future display type, was used. Additionally, the production of an entertainment styled new atmosphere is proposed.

As the idea and function of the 'Model House' alters, so does the name - 'Housing Exposition' or 'Housing Cultural Center'. Its function Is not only to show and sell but to educate, promote and show culture. It works as a 'communication ground' about house. With the growing number of the Housing Cultural Center and the importance of function, major construction companies are building it competitively to connect the relationship with clients by expanding service. However, despite the necessity of 'Housing Cultural Center' is increasing, function and component of the Housing Cultural Center are yet defined and also specific direction of design, consumer services and programs are not properly established. Also, they are promoting and selling in lots only for a limited period which have problem in clients to participate and know about the characteristics of each companies promotion. Most of Housing Cultural Centers are similar in concept, shape, color use. The purpose of this research is to analyze the Housing Cultural Center with spacial and visual elements that comprise Housing Cultural Center, and study identity factors, distinct characteristics and build identity of the Housing Cultural Center. Ultimately, companies need to put forth to make difference in their own identity and apply it effectively in order to firmly establish identity.
