The image processing device sold by the market, which increases the comfort of the driver Around-View of the camera. This system while driving or when parked, came about to prevent accidents caused by driver error or disable the visibility of the system. However, it did not spread widely to the driver due to the problem of the high installation cost and complex installation process from the system for easy operation. Due to problems such as first, expensive equipment and second, the development environment is difficult and third, inconvenient installation process, it is not out because of the prohibitively high cost burden and difficult development environment, programmers and operators. I think if this is solved even one problem of this system would be able to access the user are a little more affordable. In this paper The AVM(Around-View Monitoring) system is proposed, the two problems that minimize expensive equipment, the installation process is inconvenient problem of the three aforementioned systems. Solved the problem caused by a lot of the cost by using low-cost USB device, and a rear camera. Was developed to facilitate the installation is possible by considering the inconvenient installation. Reducing the price paid by consumers because of the system.

Background: Intraosseous anesthesia (IO) allows the anesthetic solution to be injected directly into the cancellous bone. The anesthetic solution immediately reaches the periapical region, and thus the axonal area of the nerve, where it can temporarily disable the sodium pump. The effect is felt almost without any time delay, and only a small amount of anesthetic solution is required. Methods: This study aims to investigate the efficacy of IO using the AnestoⓇ device after infiltration anesthesia (IA) and/or inferior alveolar nerve block anesthesia (IANB) failed to work in symptomatic irreversible pulpitis (hot tooth). The 33 patients included in the study were treated additionally with 1.7 ml articaine hydrochloride with 1:100,000 epinephrine hydrochloride (UltracainⓇ D-S, Sanofi-Aventis, Frankfurt, Germany) IO. Results: The electrical pulp test showed that 95.76% of the volunteers reacted positively to the combination of IANB or IA with the IO. In women, the additive IO was effective at 97.22%. In men, the IO led to pain elimination in 94.00% of cases. The duration of the IO was less than a quarter of an hour (13.03 min). The IO worked longer in women than in men (13.61 min vs. 12.33 min). Overall, more than every third tooth that needed trepanation was located in the posterior area of the mandible (36.4%). Treatment of hot teeth in this area was associated with an increased pulse rate and increased residual pain. There was a moderate correlation (Spearman-Rho [IRI] = 0.280) between the Visual Analog Scale (VAS) score and bone density, and a significant correlation (IRI = 0.612) between subjective residual pain and bone width. The IO resulted in a moderate, transient increase in the pulse rate by approximately 20 bpm. This is similar to the temporary increase in heart rate after conventional anesthesia techniques in non-preloaded patients and can be considered clinically irrelevant. Conclusion: IO with the AnestoⓇ device as an extension and deepening of local pain elimination is recommended for the treatment of hot teeth.

Objectives : The purpose of this study is to construct a model of the possible thermal runaway of electronic moxibustion and to implement an appropriate risk management method. Methods : To reproduce the system error situation of the electronic moxibustion circuit equipped with microcontroller unit, temperature sensor and heater, a code was set to disable the signal input to temperature sensor and maintain "high" heating signal to heater. The temperature change of electronic moxibustion was compared between 3 types of heater module; module 1 consisting of a combination of heater+0 ohm+0 ohm resistance, module 2 consisting of a combination of heater+Polymeric Positive Temperature Coefficient (PPTC)+0 ohm resistance, and module 3 consisting of a combination of heater+PPTC+10 ohm resistance. The temperature change was measured using a polydimethylsiloxane (PDMS) silicone phantom. After maintaining surface temperature of the phantom at 31~32℃ for 20 seconds, electronic moxibustion was applied. After operating electronic moxibustion, the temperature change was measured for 660 seconds on the surface and 900 seconds at 2 mm depth. Results : Regardless of the module type, the time-dependent change in temperature showed a rapid rise followed by a gentle curve, and a sharp drop in temperature after reaching the maximum temperature about 10 minutes after the switching the moxibustion on. Temperature measured at the depth of 2 mm below the surface increased slower and to a lesser extent. Module 1 reached highest peak temperature with largest change of temperature at both depths followed by module 2, and 3. Conclusions : Through the combination of PPTC+resistance with the heater of electronic moxibustion, it is possible to limit the rise in temperature even with the software error. Thus, this setting can be used as an independent safety measure for the electronic moxibustion control unit.

Due to the absence of rehabilitation sports service systems linked to post-discharge medical measures and rehabilitation, disabled people cannot participate in physical activities suitable for individual disability types, characteristics, and physical functions. In December 2017, the Act on the Rights of Health for the Disabled) was implemented to provide an institutional basis for disable people to address their needs for rehabilitation sports. Based on related studies conducted in Korea, this study aims to collect the results of a demand survey conducted on experts who are rehabilitation sports service providers and analyze the demand for rehabilitation sports services from a policy perspective. This study extracts the needs of experts presented in the literature and presents the extracted content as an inductive content analysis. The criteria for selecting the literature were selected based on studies related to "adaptive physical activity and exercise," "sports for all for the disabled," and "rehabilitation sports" conducted in the Republic of Korea, including the results of a demand survey on experts. The study results were categorized into seven categories (perception of sports activities, programs, leaders, facilities, accessibility, cost/support/financial resources, and others) of field experts who are rehabilitation sports service providers. In a future study, it will be necessary for people with disability, who are consumers who will provide actual services, to identify problems at the disabled sports site and come up with measures to improve them.

With the development of information and communication technology, numerous reviews are continuously posted on websites, which causes information overload problems. Therefore, users face difficulty in exploring reviews for their decision-making. To solve such a problem, many studies on review helpfulness prediction have been actively conducted to provide users with helpful and reliable reviews. Existing studies predict review helpfulness mainly based on the features included in the review. However, such studies disable providing the reason why predicted reviews are helpful. Therefore, this study aims to propose a methodology for applying eXplainable Artificial Intelligence (XAI) techniques in review helpfulness prediction to address such a limitation. This study uses restaurant reviews collected from Yelp.com to compare the prediction performance of six models widely used in previous studies. Next, we propose an explainable review helpfulness prediction model by applying the XAI technique to the model with the best prediction performance. Therefore, the methodology proposed in this study can recommend helpful reviews in the user's purchasing decision-making process and provide the interpretation of why such predicted reviews are helpful.

Purpose: Recently, there has been a movement to guarantee the right to watch sports for the disabled. However, the sports stadium is designed without considering the wheelchair users, so the right to move in the stadium is not secured. Restrictions on the movement of the disabled make the evacuation vulnerable in an emergency. This study aims to develop a plan to ensure the safety of movement and evacuation of wheelchair users by conducting simulations targeting indoor sports stadiums. Method: The simulation was performed by constructing a scenario with the shape of the stands as a variable. The effect of the installation of wheelchair seats on evacuation was confirmed. Result: The results according to whether wheelchair seats are installed, the evacuation route of wheelchair movement, and whether wheelchair seats are separately arranged were compared. The impact of wheelchair seat installation on evacuation and its characteristics were derived. As a result, upward and separation seat was the most vulnerable to evacuation. Conclusion: A plan to secure evacuation performance was derived for the top floors of upward and separation seat. It is judged that the content can be use as a way to secure the safety of movement and evacuation of the disabled in sports stadiums.

CISG Article 71 (1) states that a party may suspend the performance of his obligations if, after the conclusion of the contract, it becomes apparent that the other party will net perform a substantial part of his obligations as a result of a serious deficiency in his ability to perform or in his creditworthiness or his conduct in preparing to perform or in perfoming the contract. CISG Article 71 (2) states a 'right of stoppage in transit' that if the seller has already dispatched the goods before the grounds described in the preceding paragraph become evident, he may prevent the handing over of the goods to the buyer even though the buyer holds a document which entitles him to obtain them. The present paragraph relates only to the rights in the goods as between the buyer and the seller. Under the right of stoppage in transit, the carrier copes with risks that the seller may claim damages arose from the handing over the goods, if he hand over the goods to the buyer and that the buyer may claim damages, if he deny handing over the goods to the buyer who has the document which entitles him to obtain the goods. Therefore the legal position of the carrier may become weak. This paper purpose to point out the legal weakness of the carrier under the right of stoppage in transit and to provide the proper legal act of the carrier and possible practice related to various characters of the contract of sale of the goods. Although there is the opinion it prevent from handing over the goods to the buyer actually under the interpretation that the buyer should take claim damages to the seller, if the goods are handed over to the buyer under the right of stoppage in transit, it is not appropriate because the opinion may disable the right of stoppage in transit. The right of stoppage in transit could be carried out under any payment conditions except letter of credit and under any mode of transportation except the cases that carrier is the buyer himself or the agent of the buyer. It could be executed regardless the forms of the transport document.

The demand for medical care and welfare for patients with disabilities is expanding, and healthcare professionals are also increasingly interested in the need for medical care for patients with disabilities. The purpose of this study was to evaluate the competency of disabled patients' management and the education experience of dental hygiene students, who are the main players of oral health care for disabled patients. A total of 196 students in the dental hygiene department and 3rd and 4th grade students were surveyed using questionnaires. As a result, most of the students had a positive awareness of disabled patients; 84.7% answered with the need to train dental hygienists in specializing in handicapped patients, 76.5% were willing to attend seminars related to disabled patients after graduation, and 71.4% of the students provided dental treatment for patients with disabilities in curriculum and comparative curriculum. The students who provided treatment for disabled patients showed that their competence in most areas of knowledge of disabled patients, oral health education, and oral disease prevention was highly evaluated as significant. The competence of respondents who answered that the theoretical education was sufficient was significantly higher. Based on this, institutional support for the education of dentistry for disabled patients is needed, and sufficient theoretical education and practical training should be offered to foster personnel capable of contributing to the improvement in the oral health of patients with disabilities. In addition, in-depth discussions on the training of dental hygienists specialized in handicapped patients should be conducted.
