Bias correction of values is a necessary step in downscaling coarse and systematically biased global climate models for use in local climate change impact studies. In addition to univariate bias correction methods, many multivariate methods which correct multiple variables jointly - each with their own mathematical designs - have been developed recently. While some literature have focused on the inter-comparison of these multivariate bias correction methods, none have focused extensively on the effect of diverse configurations (i.e., different combinations of input variables to be corrected) of climate variables, particularly high-dimensional ones, on the ability of the different methods to remove biases in uni- and multivariate statistics. This study evaluates the impact of three configurations (inter-variable, inter-spatial, and full dimensional dependence configurations) on four state-of-the-art multivariate bias correction methods in a national-scale domain over South Korea using a gridded approach. An inter-comparison framework evaluating the performance of the different combinations of configurations and bias correction methods in adjusting various climate variable statistics was created. Precipitation, maximum, and minimum temperatures were corrected across 306 high-resolution (0.2°) grid cells and were evaluated. Results show improvements in most methods in correcting various statistics when implementing high-dimensional configurations. However, some instabilities were observed, likely tied to the mathematical designs of the methods, informing that some multivariate bias correction methods are incompatible with high-dimensional configurations highlighting the potential for further improvements in the field, as well as the importance of proper selection of the correction method specific to the needs of the user.

This thesis discusses a performer's unpredictability and immediacy as a prerequisite quality and/or ability to facilitate his/her professional identity as a doer on stage. To examine the key principles and approaches, this research focuses on addressing a specific aspect of the performer's transformative experience from those, directors, and practitioners' concepts that inform and enhance the performer's passive readiness on stage. To be precise, this research attempt to interrogate and articulate the place and role of a performer's internal readiness and/or that of inner looking. The performer's inner intensity as seed of action signifies that his/her body is being in a state of listening to every tiny moment with his/her heightened awareness which in turn lead the performer's body to meet the demands of theatre, the whole-body engagement. Here, this thesis argues that the key principles of acting/training underlies the importance of a performer's ethical attitude and at the same time his/her responsibility for what the performer's choices and experiences within the performative involvement, that is, a process of preparation, are not technical matter but rather, the concepts, and/or approaches from those theatre artists' practical assumptions highlight a process of thorough encountering and/or listening to his/her body. Inhabiting and/or obtaining the principles through the performer's body means being free from his/her unnecessary trait(s) which in turn initiate and then move the whole body according to what is happening in the series of moment(s) on stage. What is more, such an appropriate psychophysical order reminds us of the significance of the nature of human/performer's body, namely, to being in a state of one's 'own' body as oneness. From this perspective, this thesis further argues that the performer's body necessarily need to be affected and/or triggered in a sense of responding to the given circumstance where the performer is working on in the here and now.

Modern image inpainting techniques based on deep learning have achieved remarkable performance, and more and more people are working on repairing more complex and larger missing areas, although this is still challenging, especially for facial image inpainting. For a face image with a huge missing area, there are very few valid pixels available; however, people have an ability to imagine the complete picture in their mind according to their subjective will. It is important to simulate this capability while maintaining the identity features of the face as much as possible. To achieve this goal, we propose a three-stage network model, which we refer to as the identity and structure feature refinement network (ISFRNet). ISFRNet is based on 1) a pre-trained pSp-styleGAN model that generates an extremely realistic face image with rich structural features; 2) a shallow structured network with a small receptive field; and 3) a modified U-net with two encoders and a decoder, which has a large receptive field. We choose structural similarity index (SSIM), peak signal-to-noise ratio (PSNR), L1 Loss and learned perceptual image patch similarity (LPIPS) to evaluate our model. When the missing region is 20%-40%, the above four metric scores of our model are 28.12, 0.942, 0.015 and 0.090, respectively. When the lost area is between 40% and 60%, the metric scores are 23.31, 0.840, 0.053 and 0.177, respectively. Our inpainting network not only guarantees excellent face identity feature recovery but also exhibits state-of-the-art performance compared to other multi-stage refinement models.

The purpose of this research provides analyzes the learning attitude types by Chinese students in Korea. For this purpose, we have adopted of the practical research methodology and quantitative research methodology, which can objectively determine the individual's ideas and behavior of the "Q methodology". To this end, This research is targeted at Chinese students in the students' learning attitude implemented by 4 types and analyzes questionnaires of each type. The analysis results are categorized as the type of learning environment is not satisfied; positively cooperate with the learning process and the environment; the lack of learning motivation; and paradoxical learning state. As a result of this discussion, Chinese students should have clear motivation to learn new things; improve their korean language ability; and need to know their clear learning methods. Nowadays, more and more Chinese students are choosing study abroad. Therefore, the learning attitudes and learning abilities as two of the most important of focus from society.

MICE industry is emerging as a new growth engine recently. Most of the domestic MICE events are carried out at low cost on a small scale. The event organizers want to cut down on costs of prints such as brochures and other promotional printed materials, as well as the personnel costs for the simple guide job needed on site, which are generated repeatedly and wastefully. The existing mobile web has a defect that the participants can't easily earn the information in the fixed menu, but have to search by themselves wasting lots of time. Therefore, it is necessary to develop the solution enables providing information efficiently at low cost for short-term use during the events. In this study, we implemented specific total management system for exhibitions and convention using beacon. The information system for exhibitions and events using beacon can raise the management efficiency, and the digital brochure function based on CMS heightens the information retrieval ability and also reduces costs. Organizers can manage their event efficiently in a small exhibition and convention event by running an online website and operate a site management system by them selves.
