With the recent development of medical technology, the diagnosis rate of type 1 diabetes is increasing and patients are increasing. However, diabetes education content is not aligned with the interest level of children. As a result of the interviews with experts, It was found that the measures of coping with the change of blood sugar and the behavior therapy require steady and repetitive learning. Therefore, this study proposes Edutainment content which can be repeatedly Learned by 10~11year old children. For effective learning, the contents of the laboratory practice were constructed and the hybrid method was used for the repetitive learning. Usability test showed that this configuration is effective. This study is expected to contribute to the study of diabetic education content that is suitable for the children's level of understanding which will be developed easily in the future.

Demand for "pet plants" and "planteriers" is increasing due to the increase in COVID-19 and fine dust. In this paper, Smart pots for planterior should be small in size while providing the functions for cultivation without any problems. They should provide a user interface for long-range control for user's convenience. We implemented smart pots by incorporating IoT into pots. In response to the growing number of iPhone users, we developed an iOS app for user interface and UX/UI design. By communicating with the smartphone app and a home pot server over the Internet, users can check and control the state of the pot anytime, anywhere. The server and the pot module were separated to reduce the size of the pot itself. By locating a water bottle at the bottom of the pot, we expect that it is suitable for a "planterier" because it adopts a circulating structure in which drainage flows down to the water bottle as it is.

The purpose of this study was to assess the genetic variation and establish the relationship amongst Hanwoo, Angus and Holstein breed. The genetic characteristics and variability within Hanwoo(300), Angus(80) and Holstein(50) were estimated on the basis of relationships determined using the 10 kinds of microsatellite, which is located on different chromosomes. Frequencies of microsatellites markers were used to estimate heterozygosities, polymorphic information content(PIC) and genetic distances. The PICs ranged from 0.604 to 0.872(Hanwoo), from 0.562 to 0.812(Angus) and from 0.471 to 0.828(Holstein). Observed heterozygosity and PIC of Hanwoo are the highest among the analyzed breeds. Additionally, Estimates of genetic distance can be utilized to identify genetic relationships between Hanwoo and the other breed. Genetic distances(0.233) between Hanwoo and Angus was lower than distances between Hanwoo and Holstein(2.283). Also, Genetic distances between Angus and Holstein was shown for(2,400). The other side, each individuals were not ramified to different group and were spread evenly in phylogenetic dendrogram about all the populations.

As information technology is more actively incorporated into automobiles, the role of IVIS (In-Vehicle Infotainment System) is becoming increasingly important for providing convenience and entertainment for drivers. However, using the infotainment systems while driving requires task switching and attending to two visual resources simultaneously. We simulated a setting where participants have to drive while interacting with the infotainment system and examined how task difficulty and motor cues impact driver task-switching and driving performance, specifically whether the effects of motor cues differ depending on task difficulty. For the infotainment display, we used two types of number array depending on the congruency between the digit repetition and the chunking unit, while task difficulty was manipulated by the size of the touch-keys. Participants were instructed to dial two numbers on the screen while we recorded the dialing time, lateral position, inter-key press intervals, and steering wheel control. We found that dialing time and lateral position were affected by task difficulty, while the type of number array had no effect. However, the inter-key press intervals between chunked numbers and steering wheel movement both increased when participants had to use an incongruent number array, which indicates that, if number digits are repeated, chunking is ignored by the drivers. Our findings indicate that, in a dual-task condition, motor cues offset the effect of chunking and can effectively signal the timing for task switching.

We conducted investigations into the morphological characterstics and chemical compositions of the microlites included in the obsidians from the North Korean side Baekdusan (NK) and in the obsidian artefacts from the Busan Gadeokdo prehistoric site (BG). The morphology of the microlites from the NK can be divided into three groups, and trichite-acicular and trichite-asteroidal types are predominant. On the other hand the microlites from the BG show various morphological features such as acicular, margarite, lath, and asteroidal types. Silicate microlites from the NK are mostly of Ca-pyroxene compositions (hedenbergite to augite), whereas those from the BG are mostly of biotite (annite) with small amount of clinopyroxene (ferrosilite). It is well understood that the microlites from the NK are different from those from the BG in terms of the morphology, mineral content and mineral composition. Thus the obsidian aretefacts from the Busan Gadeokdo prehistoric site seem to have no genetical relationship to the obsidians from the Baekdusan.

The known Korean sertularian hydroid fauna consists of 41 species(including Sertularella areyi reported by Rho, 1974) of 10 genera in two subfamilies. Of which 20 species have been previously known and the following 21 species are newly recorded in Korean waters (Dynamena cornicina, Sertularella distans. Sertularella tongensis, Sertularella obtusa, Sertularella tenella, Sertularella pedrensis, Sertularella gayi, Abietinaria traski, Sertularia desmoides, Sertularia turbinata, Thuiaria suensoni, Thuiaria plumosa. Thuiaria thuia, Thuiaria nuttingi, Thuiaria similis, Thuiaria articulata, Thuiaria carica, Selaginopsis triserialis, Selaginopsis cornigera, Selaginopsis trilateralis and Selagiopsis pinnata). They were sampled from the depths below 100m. Of 41 species Sertularellla miurensis is the most common species and 10 species, Dynamena cornicina, Sertularella distans, Sertularella lagenoides, Sertularella areyi, Sertularella pedrensis, Sertularella gayi, Sertularia hattorii, Sertularia turbinata, Thuiaria plumosa and Thuiaria articulata are scarcesly founded in Korean waters. 25 out of 41 species are shared with Japan and the remaining 16 species so far have been unknown from Japan. The coastal waters of Korea are divided into three regions, the East Sea, the South Sea and the Yellow Sea, on the basis of the geographical distribution and the community coefficient. Concerning the distribution in each region, 11 species occur in the East Sea, 39 species in the South Sea and 23 species in the Yellow Sea The community coefficient between the South Sea and Yellow Sea(0.733) is higher than those of the South Sea-the East Sea (0.476) and the East Sea-the Yellow Sea(0.438).

An edutainment system aims to help learners to recognize problems effectively, grasp and classify important information needed to solve the problems and convey the contents of what they have learned. Edutainment contents can be usefully applied to education and training in the both scientific and industrial areas. Our present work proposes an edutainment system that can be applied to a drug discovery process including virtual screening by using intuitive multi-modal interfaces. In this system, a stereoscopic monitor is used to make three-dimensional (3D) macro-molecular images, with supporting multi-modal interfaces to manipulate 3D models of molecular structures effectively. In this paper, our system can easily solve a docking simulation function, which is one of important virtual drug screening methods, by applying gaming factors. The level-up concept is implemented to realize a bio-game approach, in which the gaming factor depends on number of objects and users. The quality of the proposed system is evaluated with performance comparison in terms of a finishing time of a drug docking process to screen new inhibitors against target proteins of human immunodeficiency virus (HIV) in an e-drug discovery process.

As a study of the blended learning method on design education through the blended learning method, I would like to propose that more advanced learner-led customized design education is possible. Understanding in face-to-face classes and advantages in non-face-to-face classes can be supplemented in an appropriate way in remote classes. Advanced artificial intelligence and big data technology can provide personalized and subdivided learning materials and effective learning methods tailored to learners' levels and interests based on quantified data in design classes. In this paper, it was proposed to maximize the efficiency of the class by applying a method that exceeds the limitations of time and space through the proposal of the A La Carte model (A La Carte). It is a remote class that can be heard anytime, anywhere, and it is also possible to bridge the educational quality and educational gap provided to students living in underprivileged areas. As the goal of fostering creative convergence-type future talents, it is changing with a rapid technological development speed. It is necessary to adapt to the change in learning methods in line with this. An analysis of the infographic virtual space design and construction process through the A La Carte model (A La Carte) proposal was presented. Rather than simply acquiring knowledge, it is expected that knowledge can be sorted, distinguished, learned, and easily reborn with its own knowledge.
