The expansion of the scope of product liability is necessary because the industrial environment has changed following the enactment of the Product Liability Act. Unlike human-coded algorithms, artificial intelligence is black-boxed according to machine learning, and even developers cannot explain the results. In particular, since the cause of the problem by artificial intelligence is unknown, the responsibility is unclear, and compensation for victims is not easy. This is because software or artificial intelligence is a non-object, and its productivity is not recognized under the Product Liability Act, which is limited to movable property. As a desperate measure, productivity may be recognized if it is stored or embedded in the medium. However, it is not reasonable to apply differently depending on the medium. The EU revise the product liability guidelines that recognize product liability when artificial intelligence is included. Although compensation for victims is the value pursued by the Product Liability Act, the essence has been overlooked by focusing on productivity. Even if an accident occurs using an artificial intelligence-adopted service, however, it is desirable to present standards according to practical risks instead of unconditionally holding product responsibility.

This review article summarizes the issues around platform business with government regulation. We illustrated types and characteristics of platform business. We examined the current policy tools and government activities for regulating platform business in a digital economy. Policy tools of government regulation for platform business are not suitable or fit at times. We suggest an approach to look at the fit of platform business types and regulation policy tools. We also offer a policy recommendation to define situations whether to focus on minimizing conflicts among stakeholder or invite them to participate in anticipatory decision making process for new technology market.

In this paper, it was attempted to form a titanium (Ti: Titanium) thin film using the atmospheric pressure plasma process technology for the conductor, which is the main component of the optical sensor. The atmospheric plasma equipment was remodeled. A 4-inch Ti target for sputter was etched using CF4 gas, and the by-product was coated on a glass sample. These by-products were formed up to about 2 cm, and could be divided into 15 areas according to color. Surface shape and constituent elements were analyzed using scanning electron microscopy (SEM) and energy dispersive spectrometer (EDS), respectively. Electrical properties using 4-point probe equipment were also measured. If the process is performed by positioning the sample at about 4.5 mm to 5 mm from the target, a uniform Ti thin film will be deposited. However, it was found that the thin film contained a significant amount of fluorine, which greatly affects the electrical properties of the thin film. Therefore, additional experiments and studies should be performed to remove or minimize fluorine during deposition.

The purpose of this study is to understand the characteristics of the mathematical modeling tasks and lesson designs developed by pre-service teachers based on the inherent awareness of mathematical modeling, considering the importance of creating a task to perform mathematical modeling activity and designing a lesson. As a result, the mathematical modeling tasks developed by pre-service teachers mainly presents an appropriate amount of information using real life contexts for the purpose of learning using concepts, and it showed a tendency to develop to the level of cognitive demand that required procedures with connections to understanding, meaning, or concepts. And most of the developed modeling task-based lessons showed a tendency to design warm-up activity, model-eliciting activity, and model-exploration activity. This result is due to the lack of experience of pre-service teachers in creating mathematical modeling tasks. Therefore, it is necessary to continuously provide opportunities for pre-service teachers to learn concepts or create mathematical modeling tasks intended for exploration according to various mathematical contents, thereby actively cultivating their ability to create modeling tasks in the course of training pre-service teachers. Furthermore, it is necessary to strengthen the expertise in mathematical modeling teaching and learning by providing opportunities to actually perform the mathematical modeling-based classes designed by pre-service teachers and to experience the process of reflecting on the lessons.

Obesity is known as a metabolic disease caused by abnormal differentiation of fat tissue due to an imbalance between energy intake and consumption.. The purpose of this study was to confirm the changes in the genes associated with pancreatic lipase activity and pre-adipocyte cell differentiation by treatment of red onion extract treatment. The effect of red onion extract treatment on pre-adipocyte differentiation was evaluated using 3T3-L1 adipocytes, and the activity of related genes was confirmed through Real-Time PCR. As a result of the experiment, the red onion extract inhibit pancreatic lipidase activity by concentration dependent manner. In addition, it was found to inhibit adipocyte differentiation and inhibit the activity of genes(C/EBP-α, C/EBP-β, PPAR-γ) associated with adipocyte differentiation. Through the results of this experiment, it is suggested that the red onion extract can be developed as a high potential material with anti-obesity efficacy by suppressing adipocytic differentiation by controlling genes related to adipocyte differentiation.
