The construction of virtual indoor spaces is crucial for the development of metaverses, virtual production, and other 3D content domains. Traditional methods for creating these spaces are often cost-prohibitive and labor-intensive. To address these challenges, we present a pipeline for generating digital twins of real indoor environments from RGB-D camera-scanned data. Our pipeline synergizes space structure estimation, 3D object detection, and the inpainting of missing areas, utilizing deep learning technologies to automate the creation process. Specifically, we apply deep learning models for object recognition and area inpainting, significantly enhancing the accuracy and efficiency of virtual space construction. Our approach minimizes manual labor and reduces costs, paving the way for the creation of metaverse spaces that closely mimic real-world environments. Experimental results demonstrate the effectiveness of our deep learning applications in overcoming traditional obstacles in digital twin creation, offering high-fidelity digital replicas of indoor spaces. This advancement opens for immersive and realistic virtual content creation, showcasing the potential of deep learning in the field of virtual space construction.

The arbitral award is the decision of the arbitrators on the dispute that had been submitted to them by the parties, either under the arbitration clause providing for the determination of future disputes or under submission of an existing controversy. The arbitral award has the same effect between the parties as a final and binding court judgment. The arbitration award shall acquire, as soon as it is given and delivered to each parties, the authority of res judicata in respect of the dispute it settles. The validity of an award is a condition precent for its recognition or enforcement. The validity of an award depends on the provisions of the arbitration agreement including any arbitration rules incorporated in it, and the law which is applicable to the arbitration proceedings. Such provisions usually address both the form and the content of the award. As the 'form', requires article 32 of Arbitration Act of Korea that an arbitral award should, at least, (1) be made in writing and be signed by all arbitrators. (2) state the reasons upon which it is based unless the parties have agreed that it should not, (3) state its date and place of arbitration. There are some further requirement which may have to be observed before an award which has been made by a tribunal can be enforced. (4) The duly authenticated award signed by the arbitrators shall be delivered to each of the parties and the original award shall be sent to and deposited with the competent court, accompanied by a document verifying such delivery. This rule can be interpreted as if the deposit of an arbitral award with the competent court is always required as a condition for its validity or as a preliminary to its enforcement in Korea. However, we must regard this rule which requires the deposit of an arbitral award with court, as rule of order, but not as condition of its validity. Because that the date on which the award is delivered to each party is important as it will generally determine the commencement of time limits for the making of any appeal which may be available. Furthermore, the party applying for recognition or enforcement merely has to supply the appropriate court with the duly authenticated original award or a duly certified copy thereof, not any document which proves that an the arbitral award is sent to and deposited with the competent court. In order to avoid some confusion which can be caused by its interpretation and application, the Article 32 (4) of Arbitration Act of Korea needs to be abolished or at least modified.

With the development of ICT technology, the indoor utilization of robots is increasing. Research on transportation, cleaning, guidance robots, etc., that can be used now or increase the scope of future use will be advanced. To facilitate the use of mobile robots in indoor spaces, the problem of self-location recognition is an important research area to be addressed. If an unexpected collision occurs during the motion of a mobile robot, the position of the mobile robot deviates from the initially planned navigation path. In this case, the mobile robot needs a robust controller that enables the mobile robot to accurately navigate toward the goal. This research tries to address the issues related to self-location of the mobile robot. A robust position recognition system was implemented; the system estimates the position of the mobile robot using a combination of encoder information of the mobile robot and the absolute space coordinate transformation information obtained from external video sources such as a large number of CCTVs installed in the room. Furthermore, vector field histogram method of the pass traveling algorithm of the mobile robot system was applied, and the results of the research were confirmed after conducting experiments.

In Korea, a resident registration card has various personal information such as a present address, a resident registration number, a face picture and a fingerprint. A plastic-type resident card currently used is easy to forge or alter and tricks of forgery grow to be high-degree as time goes on. So, whether a resident card is forged or not is difficult to judge by only an examination with the naked eye. This paper proposed an automatic recognition method of a resident card which recognizes a resident registration number by using a refined ART2-based RBF network newly proposed and authenticates a face picture by a template image matching method. The proposed method, first, extracts areas including a resident registration number and the date of issue from a resident card image by applying Sobel masking, median filtering and horizontal smearing operations to the image in turn. To improve the extraction of individual codes from extracted areas, the original image is binarized by using a high-frequency passing filter and CDM masking is applied to the binaried image fur making image information of individual codes better. Lastly, individual codes, which are targets of recognition, are extracted by applying 4-directional contour tracking algorithm to extracted areas in the binarized image. And this paper proposed a refined ART2-based RBF network to recognize individual codes, which applies ART2 as the loaming structure of the middle layer and dynamicaly adjusts a teaming rate in the teaming of the middle and the output layers by using a fuzzy control method to improve the performance of teaming. Also, for the precise judgement of forgey of a resident card, the proposed method supports a face authentication by using a face template database and a template image matching method. For performance evaluation of the proposed method, this paper maked metamorphoses of an original image of resident card such as a forgey of face picture, an addition of noise, variations of contrast variations of intensity and image blurring, and applied these images with original images to experiments. The results of experiment showed that the proposed method is excellent in the recognition of individual codes and the face authentication fur the automatic recognition of a resident card.

In South Korea, the number of households that rear companion animal has been gradually increasing. With the rise of household dogs, the frequency of humans that are being bitten by another's dog has also increased. This type of accident, which is known as a dog bite accident throughout the United States. It can cause significant physical and emotional damage to the victims and may result in grave injuries or death. Dog bite accidents are serious public health problems and can cause immeasurable hidden costs to the community. South Korea has enacted several laws to address dog bite accidents, which include the Animal Protection Act, the Civil Act, and the Criminal Act. On March 20, 2018, the Animal Protection Act was amended to reinforce the current legislation. These amendments addressed the duty of care owed by a companion dog owner to society members and the punishment that an owner of a fierce dog would face in the event of a dog bite accident. Conversely, several states in the United States have enacted a single law that regulates the details regarding dog bite accidents, such as the type of dog or animal, the type of damage, the scope of compensation for damages, and the scope of recognition of liabilities. This paper is intended to review the present situation of dog bite legislation in several states in the United States, which have a variety of laws that address dog bite accidents, and compare them with current South Korean dog bite legislation. Through this research, this paper will discuss what issues may exist in South Korean's current dog bite laws, analyze the responsibility of companion dog owners, and provide solutions to any issues that are discovered.

This research investigated that participants' response time and recognition in the decision-making situation would vary according to either rational or emotional stimuli and analyzed how brain functions are related to each type of stimuli by means of fMRI. We tried to address the difference of cognitive processing between rational stimuli and emotional stimuli in the perspective of information processing theory. In order to achieve the research purpose above, we conducted two kinds of experiment studies. In study 1, subjects conducted decision-making task which selected which kind of information type the stimuli was after stimuli - rational stimuli or emotional stimuli - was randomly seen during experiment. During this experiment, we investigated the effect of each stimuli by measuring the duration from the onset time at which stimuli was shown to the response time at which subjects conducted decision-making. Furthermore, we compared the brain functions by finding out what kinds of brain areas were activated during the decision-making task. In study 2, subjects conducted recognition task at which subjects made a decision whether the stimuli was sees in the previous experiment or not. During the second experiment, we investigated the recognition effect by measuring the memory for each stimuli type. Moreover, we compared the cognitive processes during recognition by analyzing the differences of brain area functions. The results of two experiments above were as following. Firstly, regarding the response time as the effect of stimuli, we found that the effect of emotional stimuli was higher than that of rational stimuli. And regarding the recognition as the effect of stimuli, it was found that the effect of rational stimuli was higher than that of emotional stimuli. Secondly, the explanation about the characteristics of cognitive processes with the result of behavioral response by analyzing brain functions was as following. First of all, regarding the decision-making task which conducted for analyzing the effect of response time, the relatively high activated brain areas of rational stimuli were related with the functions of movement control or working memory, and the relatively high activated brain areas of emotional stimuli were connected with the functions of lingual processing.

The Japan National Committee for the Union for International Cancer Control (UICC) and UICC-Asia Regional Office (ARO) organized a Roundtable Discussion as part of the official program of the UICC World Cancer Congress 2014 in Melbourne, Australia. The theme for the Roundtable Discussion was "Looking Toward the Realization of Universal Health Care 'UHC' for Cancer in Asia" and it was held on December 5, 2014. The meeting was held based on the recognition that although each country may take a different path towards the realization of UHC, one point that is common to all is that cancer is projected to be the most difficult disease to address under the goals of UHC and that there is, therefore, an urgent and pressing need to come to a common understanding and awareness with regard to UHC concepts that are a priority component of a post-MDG development agenda. The presenters and participants addressed the issue of UHC for cancer in Asia from their various perspectives in academia and international organizations. Discussions covered the challenges to UHC in Asia, collaborative approaches by international organizations, the need for uniform and relevant data, ways to create an Asia Cancer Barometer that could be applied to all countries in Asia. The session concluded with the recognition that research on UHC in Asia should continue to be used as a tool for cancer cooperation in Asia and that the achievement of UHC would require research and input not only from the medical community, but from a broad sector of society in a multidisciplinary approach. Discussions on this issue will continue towards the Asia-Pacific Cancer Conference in Indonesia in August 2015.

Objectives: Dental implants are one treatment method for tooth loss. The purpose of this study is to investigate the status of experience and intention for dental implants and related factors among elderly. Methods: The participants were 244 elderly residing in rural areas with age over 65 in Samhoeup, Yeongamgun and Jeollanamdo, Korea. Chi-square tests, t-tests, and a multiple logistic regression analysis were performed to investigate the factors influencing the experience and intention of implants. Results: Many elderlies residing in rural areas rural elderly had experienced tooth loss (83.6%). The proportion of dental implant experience was 30.9% and intention to receive implants was 57.8%. The odds ratio (OR) for experience of implants was significantly higher for participants with a lower number of chronic diseases (0: OR=12.48, 95% CI=2.12-73.38, 1: OR=4.95, 95% CI=1.66-14.72), they have dental treatment experience during the past 1 year (OR=6.61, 95% CI=1.83-23.89), they have surrounding person who have experience of implant (OR=18.06, 95% CI=2.81-115.99), higher dental implant recognition (OR=3.97, 95% CI=1.92-8.23). The odds ratio (OR) for dental implant intention was significantly higher for participants with a lower age (65-69: OR=8.18, 95% CI=2.38-278.08, 70-79: OR=3.17 95% CI=1.04-9.68), lower number of chronic diseases (0: OR=4.15, 95% CI=1.00-17.29), they have drink alcohol (OR=5.03, Cl=1.31-19.34), they have surrounding person who has experience of implant (OR=3.22, 95% CI=1.30-8.02), they have not experience of tooth loss (OR=4.65, Cl=1.22-17.70), higher dental implant recognition (OR=2.69, 95% CI=1.55-4.67). Conclusions:In the future, it is necessary to utilize the results of this study to address loss of teeth and to support dental implant treatment selection through improved increased awareness of the advantages and disadvantages of dental implants.

At the industrial work site, the manufacturing process is being automated to improve work efficiency. However, it is often difficult to automate the entire manufacturing process, and there are spaces in which workers there are constantly exposed to danger. To protect such workers from the danger, this paper studied a worker safety management system for the industrial work site which uses a location recognition system and which is based on the Ubiquitous-Wireless Sensor Network (U-WSN). Using wireless signals, the distance between two devices can be measured and the location of a worker can be calculated using triangularization in 3-D. But at the industrial work sites where there are a lot of steel and structures, errors occur due to signal reflection and multi-path, etc., which makes it difficult to get the accurate location. To address this problem the following was done: first, a circular polarization patch antenna appropriate to the work site was used to reduce the degree of error that may occur from the antenna emission pattern and the particular Line of Sight (LOS); second, a 3-D localization technique and a filtering algorithm were used to improve the accuracy of location determination. The developed system was tested by using it on a wharf crane to validate its accuracy and effectiveness. The proposed location recognition system is expected to contribute greatly in ensuring the safety of workers at industrial work sites.
