This study compared the antioxidant and mineral properties of the leaves and seeds of fifteen Korean adzuki bean (Vigna angularisL.) breeding lines. This study was conducted in an attempt to expand the use of Korean adzuki bean leaves. The potassium, calcium, magnesium, and sodium contents of the leaves were significantly higher than the seeds, in particularly, the potassium content. The leaves had approximately 3.3 times higher potassium content than the seeds. For instance, the potassium content of YA1317 leaves was 21% higher than that of Arari. The total polyphenol content and ABTS activity of Adzuki bean leaves were significantly higher than the seeds, as opposed to the total flavonoid content and DPPH scavenging activity. Among the 15 breeding lines, YA1402 had 1.2~3.2 times higher antioxidant content and activity as compared to the Arari variety. It was concluded that adzuki bean leaves had higher mineral content, antioxidant component and activity as compared to the seeds. Therefore, adzuki bean leaves could be used an ingredient for dishes and as a medicine.

The Ministry of Agriculture, Food and Rural Affairs established the FarmMap, an digital map of agricultural land. In this study, using deep learning, we suggest the application of farm map reading to farmland such as paddy fields, fields, ginseng, fruit trees, facilities, and uncultivated land. The farm map is used as spatial information for planting status and drone operation by digitizing agricultural land in the real world using aerial and satellite images. A reading manual has been prepared and updated every year by demarcating the boundaries of agricultural land and reading the attributes. Human reading of agricultural land differs depending on reading ability and experience, and reading errors are difficult to verify in reality because of budget limitations. The farmmap has location information and class information of the corresponding object in the image of 5 types of farmland properties, so the suitable AI technique was tested with ResNet50, an instance segmentation model. The results of attribute reading of agricultural land using deep learning and attribute reading by humans were compared. If technology is developed by focusing on attribute reading that shows different results in the future, it is expected that it will play a big role in reducing attribute errors and improving the accuracy of digital map of agricultural land.

Since the enactment of the Act on the Management of Presidential Archives in 2007, the cases of electronic records transfer in the 16th President Roh Moo-hyun's administration have played the role of an advance guard in managing public records and served as a test bed for new electronic records management. When transferring the electronic records of the 19th President Moon Jae-in's administration, the electronic records transfer method of President Roh's administration was inherited, while several innovative attempts were made. For instance, the Presidential Archives have for the first time converted the electronic documents from institutions advising the President into a long-term preservation package and transferred them online. In addition, considering the characteristics of the data, the administrative information dataset of the Presidential record creation institutions was transferred to the SIARD standard. Furthermore, the Presidential Archives had websites transferred in the form of OVF as a pilot test and collected social media directly through the API. Thus this study investigated the transition process of the presidential electronic records transfers from the 16th President Roh Moo-hyun's administration to the 19th President Moon Jae-in's. In addition, major achievements and issues were analyzed centering on the transfer method by type of electronic records during President Moon Jae-in's administration, and future improvement plans were presented.

Most countries worldwide are finding it difficult to make decisions regarding the utilization of water resources and the ecological flow protection of rivers because of serious water shortages and global climate warming. To overcome this difficulty, accurate ecological flow processes and protected ecological objectives are required. Since the introduction of the concept, ecological flow calculations have been developed for more than 60 years. This technical development has always been dominated by countries such as the United States, Australia, and the United Kingdom. The technical applications, however, vary substantially worldwide. Some countries, for instance, did not readjust the method because of a lack of understanding of the ecological effect or because they failed to achieve elaborate scheduling. Mostly, readjustments were not made because the users could not make their choices from among numerous methods for ecological flow. This paper presents three research results based on a systematic review of 240 methods with clear connotation boundaries. First, the ecological flow algorithm was developed along with the scientific and technological progress in the river ecosystem theory, ecohydrological relationship, and characterization and simulation of hydrological and hydrodynamic processes. In addition, the basis of the method has evolved from the hydrological process of the ecosystem, hydraulics-habitat conditions, and social development interference to whole ecosystem simulation. Second, 240 methods were classified into 50 sub-categories to evaluate their advantages and disadvantages according to the ecological flow algorithms of hydrology, hydraulics, habitat, and other comprehensive methods. According to this evaluation, 60% of the methods were not suitable for further application, including the method based on the percentage of natural runoff. Furthermore, the applicability of the remaining methods was presented according to the evaluation based on the aspects of allocation of water resources, water conservancy project scheduling, and river ecological evaluation. Third, In the future, most developing countries should strengthen the guarantee of high-standard ecological flow via a coordination mechanism for the ecological flow guarantee established under a sustainable framework or via an ecological protection pattern at the national level according to the national system. Concurrently, a reliable ecological flow demand process should also be established on the basis of detailed investigation and research on the relationship between river habitats, ecological hydrology, and ecological hydraulics. This will ensure that the real-time evaluation of ecological flow forces the water conservancy project scheduling and accurate allocation of water.

The objective of this study is to design a system that automatically monitors the state of interior spaces like offices where lots of people are coming and going through image data and environment data, which includes temperature, humidity, and other conditions, and implement and test related application programs. In practice, there are lots of image data automatically obtained by unmanned equipments, such as certain types of CCTVs, for monitoring situation in usual interior spaces. This image data can be used as a more effective manner by establishing a system that recognizes situation in specific interior spaces based on the relationship between image and environment data. For instance, it is possible to perform unmanned on/off controls for various electronic equipments, such as air conditioners, lights, and other devices, through analyzing the data acquisited from environment sensors (temperature, humidity, and illumination) as dynamic states are not maintained for a specified period of time. For implementing these controls, this study analyzes environment data acquisited from temperature and humidity sensors and image data input from wireless cameras to recognize situation and that can be used to automatically control environment variables configured by users. Experiments were applied in a laboratory where unmanned controls were effectively performed as automatic on/off controls for the air conditioner and lights installed in the laboratory as certain motions were detected or undetected for a specified period of time.

In recent years, South Korean has made a globally acknowledged achievement in movie industry. In terms of Art, films produced in South Korea obtained lots of awards in international movie festivals; in the business field, Korean movies are swiftly occupying the Asian or even the world film market. Extraordinary films with good reputations and high box office records are frequently launched and induced to a trend, which then forms into a cultural phenomenon and attributes to an important, major force in the so-called "Hallyu" culture. This, in part, benefits from the massive support of Korean government's cultural policies, and is also a product of the high degree of cultural consciousness of Korean movie producers. The Korean cultures, customs, and the underlying cultural elements of the East, that are presented in these movies, satisfy the audience and appeal their fondness. The Princess and the Matchmaker is a South Korean period romantic comedy film directed by Hong Chang-pyo and starred Shim Eun-kyung and Lee Seung-gi. The movie was presented on Feb 28th, 2018. It tells a story of Seo Do-yoon, the most proficient saju (fortune-teller) expert of the Joseon Era who selected a husband for Princess Song-Hwa based on her "fortune eight letters" (specifically, the time, day, month and year of her and her husbands' birth, normally in eight letters), in a hope of alleviating the rage of people following years of drought, and thus to resolve a national crisis. This paper takes The Princess and the Matchmaker as an example, from the aspects of cultural state, system, behavior and mentality, to analyze the traditional customs such as "fortune eight letters", "marriage by match" and the cultural concepts behind these phenomena, in order to explore the ways and methods of traditional culture in the modern cultural and artistic form of film.

In this paper, this author studied the realization of Daesoonjinri's Haewon Sangsaeng(解冤相生) in this world, for instance discussed the meaning of Daesoonjinri's Haewon Sangsaeng, a world construction with Haewon Sangsaeng, its practical action for the realization of Haewon Sangsaeng, and so forth. A description of the contents is as follows. Daesoonjinri's Haewon Sangsaeng eliminates the resentment of human destiny, and provides the grounds that we peoples can live with, going to help each other. And then the realization of Daesoonjinri's Haewon Sangsaeng in this world will require us to this society. Really Sangje(上帝) wanted to perform it in this world, and has performed it with a reorganizing in the order of heaven and the earth(天地公事). In response to the deeper sublimest will of Sangje, we humans can not help but do as follows: When Sangje has done a reorganizing in the order of heaven and the earth, we humans should participate in it. This is our response to the will of Sangje who wants to build an ideal society in this world. And in oder to participate in a reorganizing in the order of heaven and the earth, we humans should look up Sangje with Sincerity(誠), Reverence(敬), and should practice the words of Sangje with Faith(信). This kind of thing is a route that we should avoid Jeokwon Sanggeuk(積怨相克) and should perform Haewon Sangsaeng. This Haewon Sangsaeng can be achieved with no Chuck(無慼), an altruistic, no greed(無慾), an execution of asceticism(修道), and the practice of Podeok (布德)·Rehabilitation(敎化). No making of a Chuck, doing an altruistic, no greed, an execution of asceticism would not deceive others, would not murder others, would not blame the transgressions of others, would not discriminate, would not harm others. And Podeok·Rehabilitation should be performed well in practice. When performing Podeok and Rehabilitation, we should not nullify them as unjust words or undue actions, and we must be a true. Because we must make the words of Sangje inform a world wide well, and must convince the words of Sangje to peoples so that they can adhere to them with a faith. That's the way that we humans should participate in a reorganizing in the order of heaven and the earth in this current world, and the way that we should contribute to building the ideal society in the world.

Brown rats (Rattus norvegicusBerkenhout, 1769) were eradicated from Sasudo Island (33°55'13.04" N, 126°38'19.98" E), an uninhabited island designated as Natural Monument No. 333 and the largest breeding site for the streaked shearwater (Calonectris leucomelasTemminck, 1835) in South Korea. Twelve eradication studies were conducted from November 2015 to February 2021. The survey was conducted using a line census method that entailed slow wandering throughout the island and identifying starting and returning points. Capture traps were installed around traces of Rattus norvegicus,such as excrement and identified holes. As a result, 2 to 6 individuals were captured at each instance, except for the last time, when no individuals were captured. It is hypothesized that brown rats arrived at Sasudo Island via vessels arriving at the island for leisure and fishing. After the damage to streaked shearwater caused by brown rats was confirmed in 2006, entry to Sasudo Island was strictly prohibited through security measures, and marine clean-up programs that began in 2013 and continuous capturing since 2015 have been successful in eradicating brown rats. To maintain and manage the condition in Sasudo Island, preservation and management measures, such as strict visitor control, are necessary to prevent the inflow of new brown rats in the future.
