In order to shoot underwater, the photographer must be equipped with shooting equipment and enter into the water. Since the photographer directly enters the water, safety accidents occur frequently due to various obstacles or deep water in the water. The proposed underwater stereo photography technique can solve the safety accident problem caused by the entry of the photographer into the water by using the drone for underwater photographing. In addition, this technique has the advantage of obtaining underwater images at low cost. In this study, the angle of the proposed cam for stereoscopic photography was analyzed and the condition that the proper stereoscopic image can be viewed was defined as the distance from the floor of 18cm to the floor distance of 41.4cm. This provision is proposed to be used to adjust the height of the shooting area descended by the elevation chain of the water surface hovering drones.

Modern financial services go beyond the stage of internet banking, and new concepts of financial transactions such as Internet of Things, mobile banking, electronic payments, and fintech have emerged. As a result, banks are less influential in financial transactions, and changes are being demanded. In the present era, the basic business of banks has decreased, and it is transforming into a space where both consumer finance work and reside. The bank office stands for the brand image of the bank, and it is represented by trust with customers in the basic business of financial transactions, and the rise in real estate value is a natural social phenomenon due to the nature of the location and location of real estate owned by the bank. The business method and space of the bank office that meets the new paradigm of the modern society is an inefficient space only for the convenience and rest of consumers, but it must be used as a variety of spaces suitable for the region to increase the functional value of the bank office. Through this study, as a convenience space for consumers, various service facilities should be introduced to understand the characteristics of the region as a convenience space for consumers, and various service facilities should be introduced to meet the needs of consumers, and the bank office should be improved as a complex service space for local residents.

The type of crimes is diverse and the number of crimes is increasing as society changes. This phenomenon is showing a higher trend in places with higher population density. Accordingly, many organizations install CCTV to reduce crime and provide key evidence of crime. Nevertheless, it is still weak to deal with crimes such as video manipulation targeting CCTV. Although blockchain-based CCTV image integrity techniques are applied to prevent manipulation, they only guarantee the manipulation integrity of the entire video and can't explain how certain sections of the video has been manipulated. Therefore, in this research, we propose a system for supporting explainable CCTV video integrity based on a block chain.

With the development of deep learning technology, various research and development are underway to estimate preference rankings through learning, and it is used in various fields such as web search, gene classification, recommendation system, and image search. Approximation algorithms are used to estimate deep learning-based preference ranking, which builds more than k comparison sets on all comparison targets to ensure proper accuracy, and how to build comparison sets affects learning. In this paper, we propose a k-disjoint comparison set generation algorithm and a k-chain comparison set generation algorithm, a novel algorithm for generating paired comparison sets for crowd-sourcing-based deep learning affinity measurements. In particular, the experiment confirmed that the k-chaining algorithm, like the conventional circular generation algorithm, also has a random nature that can support stable preference evaluation while ensuring connectivity between data.

Purpose: This study was conducted to compare dental plaque scores obtained through clinical examinations and various imaging techniques, as well as to assess the effectiveness of herbal and conventional toothpastes for plaque removal. Materials and Methods: Thirty volunteers were divided into 3 groups. Each group was given a different toothpaste (from 2 herbal toothpastes and a conventional toothpaste) with which to brush their teeth for 21 days. Both initially and after brushing, dental plaque samples were collected, and plaque on the buccal surfaces of anterior teeth was scored using several imaging systems after staining with a disclosing agent. Specifically, digital dental photography, intraoral digital scanning, and FluoreCam imaging were employed to capture intraoral images. The Turesky Modified Quigley-Hein Plaque Index was used for clinical examination and image analysis. Quantitative polymerase chain reaction analyses and correlational assessments between clinical examination and imaging scores were conducted before and after toothpaste use. The Shapiro-Wilk test and Pearson correlations were utilized. Results: The lowest mean value was observed in the clinical examination without staining, while the highest was obtained using the FluoreCam method. No significant change was found in the level of any microorganism assessed following toothpaste use (P<0.05), with the exception of a decrease in S. mutans levels after using conventional toothpaste (P<0.05). Conclusion: Herbal toothpaste demonstrated plaque-removal effectiveness comparable to that of conventional toothpaste. The use of imaging methods for measuring plaque index has been suggested as a means to educate patients about plaque control and promote ongoing oral care.

The mitochondrial DNA(mtDNA) D-loop region was amplified from Duroc(Sus scrofa) by polymerase chain reaction(PCR). The oligonucleotide primer used to amplify the Sus scrofa mtDNA D-loop region was designed using tRNA-Pro and tRNA-Phe sequence in mtDNA regions highly conserved in many other animal species. There were 1,145 base pairs(bp) in the D-loop region. The middle of the region contained 10 tandem repeat of an 10-bp Sus scrofa-specific sequence, TACACGTGCG. We designed primers for PCR-mediated single stranded conformation polymorphism(SSCP) analysis that amplified a 345 bp fragment, which contained the most variable region according to our sequencing data. SSCP analysis of denatured amplification products was carried out by polyacrylamide(8%) gel electrophoresis followed by ethidium bromide staining. The SSCP analysis identified two band patterns(A and B) and comparision of these two nucleotide sequences identified 21 base substitutions. These results show that SSCP analysis of the D-loop region is useful for detecting the genetic polymorphism.

Camp Page, which has been located in front of Chuncheon Station for about 50 years since 1958, recently opened to the public. Chuncheon City is currently struggling to construct a park on this site due to an uncertainty of general plans and financial difficulties. Accordingly, this research conducted a cognitive survey about site usage with Camp Page users in order to clarify directions for efficient establishment of parks within the former military base. The course of research includes analytical methods such as a survey targeting Chuncheon citizens and tourists both in the field and online, a frequency analysis of 1,360 index samples, a cross analysis and t-test. As a result, firstly, Chuncheon citizens recognized the image of Chuncheon as a city with a fresh, clean lakeshore whereas tourists think of it as a city for sightseeing and leisure. Hence, it was justifiable to conclude that the city should organize various programs for people to enjoy leisure activities while at the same time protecting the environment. Second, the awareness of tourists about Camp Page was relatively low and both citizens and tourists recognize that it was not sufficient enough for enjoyment of free time. The majority answered "space for culture and art and for experiencing the natural environment" when asked about the direction of space creation at Camp Page, which indicates that the site will need to be available both for cultural art and nature experiences. Lastly, it was thought that the direction of developing leisure facilities in Chuncheon city should include the improvement of worn out installations and developing chain products among programs. This research will be able to use fundamental data for the efficient utilization of the returned U.S. military camps that are constantly merging.

Recently, the perception of Corporate Social Responsibility (CSR) has changed. Until now, corporate social responsibility has been recognized as a temporary means to improve the image of a company, but there is a growing recognition that it is a prerequisite for sustainable growth of the entity. Social responsibility of enterprises has altered according to the times and economic environment, and as the global value chain has become important, it has become a growth strategy for small and medium-sized exporters. Under these circumstances, CSR is increasingly an integral part of the activities of companies, and this is no exception for small and medium-sized enterprises. Nevertheless, Korean small businesses' CSR is still lacking, and so the case of Japan, where CSR has spread to small and medium-sized businesses despite the short period of time, is believed to give us policy implications. In the Japanese case, corporate social responsibility has been traditionally passed down by Omi merchants in the 17th century. The social responsibility of a company they thought was summed up by the so-called "sanspo-yoshi spirit" that is beneficial to sellers, benefits to buyers and helps society. Based on the case of Japan's CSR, which has been applied smoothly even to its small and medium-sized companies, this paper intends to suggest the following policy implications. First, the establishment and dissemination of a national long-term plan is necessary. Second, it is urgent for smaller businesses to introduce their strategic CSRs. Third, CSR, which does mutual cooperation between large and small businesses, should be pursued.
