Grievance resolution, gratitude and mutual beneficence are not only an essential dogma of Daesoonjinrihoe but also a major issue which Chinese Confucian scholars have been concerned about. In this context, this study compares the perspectives of grievance resolution, gratitude, mutual beneficence based on basic scriptures of Daesoonjinrihoe and ancient Chinese Confucianism. With nurture and benevolence as core thoughts, the ways of ruling the world in righteousness and proprieties have common characteristics of Daesoonjinrihoe and Confucianism. The Heavenly Way, which is rather an abstract conception, is perceived as a Confucianism ultimate ground. Because Confucianism does what is right for nurture, embracing rationality, the religious aspects are not clearly defined, it is the difference between Daesoonjinrihoe and Chinese Confucianism. In this regard, this study compares similarities and differences between the two cultures to promote mutual understanding.

This paper presents a real-time low-resolution face recognition method that uses a super-resolution technique. Conventional face recognition methods are limited by low accuracy resulting from the distance between the camera and objects. Although super-resolution methods have been developed to resolve this issue, they are not suitable for integrated face recognition systems. The proposed method recognizes faces with low resolution using key frame selection, super resolution, face detection, and recognition on real-time processing. Experiments involving several databases indicated that the proposed algorithm is superior to conventional methods in terms of face recognition accuracy.

A scenario known as conflict in face recognition may arise as a result of some disparity-related issues (such as expression, distortion, occlusion and others) leading to a compromise of someone's identity or contradiction of the intended message. However, addressing this requires the determination and application of appropriate procedures among the various conflict theories both in terms of concepts as well as resolution strategies. Theories such as Marxist, Game theory (Prisoner's dilemma, Penny matching, Chicken problem), Lanchester theory and Information theory were analyzed in relation to facial images conflict and these were made possible by trying to provide answers to selected questions as far as resolving facial conflict is concerned. It has been observed that the scenarios presented in the Marxist theory agree with the form of resolution expected in the analysis of conflict and its related issues as they relate to face recognition. The study observed that the issue of conflict in facial images can better be analyzed using the concept introduced by the Marxist theory in relation to the Information theory. This is as a result of its resolution strategy which tends to seek a form of balance as result as opposed to the win or lose case scenarios applied in other concepts. This was also consolidated by making reference to the main mechanisms and result scenario applicable in Information theory.

Predicting the location and intensity of precipitation still remains a main issue in numerical weather prediction (NWP). Resolution is a very important component of precipitation forecasts in NWP. Compared with a lower resolution model, a higher resolution model can predict small scale (i.e., storm scale) precipitation and depict convection structures more precisely. In addition, an ensemble technique can be used to improve the precipitation forecast because it can estimate uncertainties associated with forecasts. Therefore, NWP using both a higher resolution model and ensemble technique is expected to represent inherent uncertainties of convective scale motion better and lead to improved forecasts. In this study, the limited area ensemble prediction system for the convective-scale (i.e., high resolution) operational Unified Model (UM) in Korea Meteorological Administration (KMA) was developed and evaluated for the ensemble forecasts during August 2012. The model domain covers the limited area over the Korean Peninsula. The high resolution limited area ensemble prediction system developed showed good skill in predicting precipitation, wind, and temperature at the surface as well as meteorological variables at 500 and 850 hPa. To investigate which combination of horizontal resolution and ensemble member is most skillful, the system was run with three different horizontal resolutions (1.5, 2, and 3 km) and ensemble members (8, 12, and 16), and the forecasts from the experiments were evaluated. To assess the quantitative precipitation forecast (QPF) skill of the system, the precipitation forecasts for two heavy rainfall cases during the study period were analyzed using the Fractions Skill Score (FSS) and Probability Matching (PM) method. The PM method was effective in representing the intensity of precipitation and the FSS was effective in verifying the precipitation forecast for the high resolution limited area ensemble prediction system in KMA.

Among the main technologies to implement 3D TV succeeding HDTV, multi-viewpoint image display technique is rising as an important issue, which can display the viewpoint-dependent images corresponding to viewer's position. This paper presents a novel method that solves too much computational overload that is main drawback of previous methods. Using down sampling technique, multiresolution EPIs are made from multi-viewpoint image set and trace lines are detected in the lowest resolution EPI. The parameters of detected trace lines are transferred to higher resolution EPIs and revised by utilizing the information of the previous resolution EPI. This procedure is iterated until orignal resolution EPI. Using the proposed method, we have achieved the reduction of computational time and the robustness to noise in comparison to previous method.

General lawsuits can be chosen as a method of resolving patent disputes. However, a significant amount of time and money is wasted on litigation until the dispute is resolved. The Intellectual Property Framework Act in Korea requires the government to simplify litigation procedures and improve litigation systems to resolve intellectual property disputes quickly and fairly. As a result, accurate and timely resolution of patent disputes is given importance by the Korean government. Interest in arbitration as an alternative method of dispute resolution is growing. Although dispute resolution through arbitration is effective, the issue of resolving patent disputes through arbitration can lead to the arbitrability of patent disputes. It is therefore necessary to examine arbitrability of patent contracts and validity disputes. Korea has made efforts to reflect the model arbitration law of the United Nations Commission on International Trade Law for quick judicial resolution of patent disputes. Korea has also strengthened related systems for alternative resolutions. However, improving the arbitration system will necessitate a thorough examination of the systems and practices of the United States which is the country in the forefront of intellectual property. This paper examines the arbitrability of Korea's patent dispute and makes recommendations for more efficient dispute resolution system changes.

Purpose: As cone-beam computed tomography (CBCT) has become the most widely used 3-dimensional (3D) imaging modality in the dental field, storage space and costs for large-capacity data have become an important issue. Therefore, if 3D data can be stored at a clinically acceptable compression rate, the burden in terms of storage space and cost can be reduced and data can be managed more efficiently. In this study, a deep learning network for super-resolution was tested to restore compressed virtual CBCT images. Materials and Methods: Virtual CBCT image data were created with a publicly available online dataset (CQ500) of multidetector computed tomography images using CBCT reconstruction software (TIGRE). A very deep super-resolution (VDSR) network was trained to restore high-resolution virtual CBCT images from the low-resolution virtual CBCT images. Results: The images reconstructed by VDSR showed better image quality than bicubic interpolation in restored images at various scale ratios. The highest scale ratio with clinically acceptable reconstruction accuracy using VDSR was 2.1. Conclusion: VDSR showed promising restoration accuracy in this study. In the future, it will be necessary to experiment with new deep learning algorithms and large-scale data for clinical application of this technology.

Inkjet technology is one of the commonly used technologies in the printed-electronics field. The primary issue regarding the usage of inkjet technology as a printed-electronics tool is the printing resolution; therefore, to print complicated patterns of precise dimensions, we developed software that can convert a CAD file into a bitmap image. Moreover, as a bitmap image is not comprised of physical dimensions, its resolution needs to be defined in terms of pixel distance to print a rasterized bitmap image. In this study, we investigated the effects of pixel distance and dot size on printing resolution; based on the experiment results, we concluded that the printed dot size should be used to determine the optimal pixel distance. Lastly, we also propose inkjet printing procedures for bitmap images.

Drop-on-Demand (DOD) inkjet printing technology, especially piezo-typed, has been paid attention by industries due to its inherent nature of unbeatable material usage and low cost manufacturing cost. Despite of these key advantages over any other competing manufacturing technologies, the primary disadvantage has been considered as its limited capability to produce fine resolution patterns with a commercially available DOD inkjet print head. Although the main effort has been focused on the production of a DOD inkjet print head with smaller nozzles to overcome this challenging issue, an alternative approach could be taken and it would enable to expand the employment of DOD inkjet printing technology to applications requiring fine patterns further more.
