In this study, we delve into the potential for innovative cultural education techniques that utilize the timeless tales of Princess Bari and The Tale of Shim Cheong as tailored for the upcoming generations of overseas Korean learners. With a rising number of young overseas Koreans born and raised in their host countries, there emerges a pressing need to craft an educational framework that resonates with the evolving dynamics of their generation. Our endeavor revolves around proposing educational strategies that help solidify identity while carefully considering the intrinsic motivation prevalent among most overseas Koreans. Naturally, the choice of employing the classic epics Princess Bari and The Tale of Shim Cheong as educational resources was deliberate. These narratives are rich in rites of passage and offer profound insights into the transformative journey of their protagonists. Both characters are affluent women in patriarchal societies, and both embark on quests to redefine themselves through new relationships, liberating themselves from the confines of parental ties. This narrative framework provides a unique opportunity for overseas Koreans who are often adrift in the social fabric of their adopted countries. These stories inspire them to introspect and contemplate their own identities. By intertwining their personal narratives with the empowering stories of characters, students are provided a chance to reaffirm their authentic selves. Therein, a paradigm shift can occur that allows individuals to embrace the core elements that define them. Our ultimate objective was to enable students to explore their own stories and immerse themselves in the intricate narratives of classical works. This immersive experience fosters a profound sense of unity with the characters and paves the way for a comprehensive educational plan. This plan not only celebrates the hybrid nature of identity but also cultivates a deep sense of positivity within amalgamated 'subjects.' Such an approach not only fosters a stronger connection with one's heritage but also sparks a genuine curiosity about and affinity for the rich cultural tapestry of one's home country. It's not just education; it's a transformative journey that enriches the lives of overseas Koreans and nurtures a profound bond with their cultural roots.

Climate change has increased extreme weather events likewise heatwaves, heavy rain, and drought. Unlike other natural disaster, drought is a slowly developing phenomenon and thus drought damage increases as the drought continues. Therefore, it is necessary to understand the characteristics and mechanism of drought occurrence. Agricultural drought occurs when the water supply needed by crops becomes insufficient due to lack of soil water. Therefore, soil water is used as a key variable affecting agricultural drought. In this study, we examined the spatio-temporal distribution and trends of drought across the Korean Peninsula by determining the soil available water content (SAWC) through a model that integrated soil, meteorological, and crop data. Moreover, an investigation into the correlation between meteorological variables and the SAWC was conducted to assess how meteorological characteristics influence the nature of drought occurrences. During the soybean cultivation period, the average SAWC was lowest in 2018 at 88.6% and highest in 2021 at 103.2%. Analysis of the spatial distribution of SAWC by growth stage revealed that the lowest SAWC occurred during the flowering stage (S3) in 2018, during the leaf extension stage (S2) in 2019, during the seedling stage (S1) in 2020, again during the flowering stage (S3) in 2021, and during the seedling stage (S1) in 2022. Based on the average SAWC across different growth stages, the frequency of upland drought was the highest at 22 times during the S3 in 2018. The lowest SAWC was primarily influenced by a significant negative correlation with rainfall and evapotranspiration, whereas the highest SAWC showed a significant positive correlation with rainfall and relative humidity, and a significant negative correlation with reference evapotranspiration.

This study was conducted to investigate form of pollution brought by residual of mine tailing in agricultural land, and get basic information need for environment restoration. Guundong mine was completely restored region by implementation the soil pollution prevention plan. The districts is soils in Guundong mine vicinity the Mahul-ri, Muan-myeon, Miryang city, Gyeongsangnam-do. The nature of soil studied is the Shinra series andesite and mineral deposits which contain brimstone and heavy metals such as gold, silver, copper, lead, and zinc. The residual mine tailing and around agricultural land of heavy metals analyzed with 0.1N HCI solubility. The chemical properties of surface soil in upper part around mining area were pH 4.3-4.4, organic matter 19-21 g $kg^{-1}$, available $P_2O_5$ 85 mg $kg^{-1}$, exchangeable Ca 0.21-0.25 $cmol_c\;kg^{-1}$, exchangeable Mg 0.04 $cmol_c\;kg^{-1}$. The pH, exchangeable Ca, and Mg were increased with soil depth. The contents of 0.1N HCl extractable Cu, Cd, Pb, Cr, and Ni in soil (siteI) which influenced by outflow water from mine tailing were 97, 0.6, 197, 0.28 및 0.12 mg $kg^{-1}$, respectively. The vertical distribution of heavy metals in soil varied considerably among the metals kind. In case of siteI, The content of Cu, Pb, and Cr in soil was highest at surface soil. However, the content of Cd, Zn, Ni, and Mn was high at middle part of soil profile.

By the revision of the Commercial Code of Korea in 1991 and 2007, some provisions for the regulation of Time Charterparty have been introduced into our own maritime law system. But, those provisions are in their nature mainly the reproduction of the provisions prescribed in the standard forms of time charterparty which are widely used, such as BALTIME Charter and NYPE Form, and the subject matters of their regulation are restrictive, so that the applicability of the provisions is not desirable. The cargo is lost or damaged, the cargo owner should seek compensation form, or sue, the carrier as, traditionally, under the COGSA, the cargo carrier is responsible for loss of damage of cargo. However, it is difficult to determine who is the responsible carrier under charters. There is no test to determine the carrier, but the courts in every country generally consider the bill of lading. Although the master has general authority to sign bills of lading on behalf of the shipowner, he can also sign bills of lading for, and on behalf of, the charterer. In this case, the charter is considered the carrier. Furthermore, the charterer is authorized to contract with third parties on behalf of the shipowner and, as such, the responsible carrier is the shipowner. Therefore, when determining the carrier we should examine carefully the all factors and the circumstances surrounding the case. Also, negligence of a captain of a time-chartered ship causing damages to a third party. It will analyze the legal character of a time-charter contract, review judicial precedents on time-charter. The Inter-Club Agreement was drawn up and is intended to be a somewhat easier way of allocating liability for cargo claims between owners and charterers and, although there is still scope for disputes to arise, the Inter-Club Agreement does in fact to some extent make the allocation of liabilities for cargo claims easier. Finally, it will also make legislative suggestions to resolve complex issues involving maritime transportation contracts under the current Commercial Code.

In this study, to retain a stable bacterial inoculant, Bacillus strains showing antifungal activity were screened. The improved production, antifungal mechanism, and stability of the antifungal metabolite by a selected strain, AF4, a potent antagonist against phytopathogenic Botrytis cinerea, were also investigated. The AF4 strain was isolated from rhizospheric soil of hot pepper and identified as Bacillus subtilis by phenotypic characters and 16S rRNA gene analysis. Strain AF4 did not produce antifungal activity in the absence of a nitrogen source and produced antifungal activity at a broad range of temperatures (25-40℃) and pH (7-10). Optimal carbon and nitrogen sources for the production of antifungal activity were glycerol and casein, respectively. Under improved conditions, the maximum antifungal activity was 140±3 AU/ml, which was higher than in the basal medium. Photomicrographs of strain AF4-treated B. cinerea showed morphological abnormalities of fungal mycelia, demonstrating the role of the antifungal metabolite. The B. subtilis AF4 culture exhibited broad antifungal activity against several phytopathogenic fungi. The antifungal activity was heat-, pH-, solvent-, and protease-stable, indicating its nonproteinous nature. These results suggest that B. subtilis AF4 is a potential candidate for the control of phytopathogenic fungi-derived plant diseases.

Bangseonmun(訪仙門) is the attractive spots where Shinseon(神仙: Taoist hermit) ideas that makes Mt. Younju(瀛洲山) or the current Mt. Halla mystique has still remained and situated at Hancheon(漢川) Valley. Bangseonmun, which is known as 'Landscape Setting Here($L_{SH}$)' of Youngguchunhwa(瀛丘春花), which is one of ten famous spots in Youngjusipkyung(瀛洲十景), and Deulreonggui refer to 'the gate to the place where Shinseon is living.' It is described as the path to Mt. Youngju for Shinseon and the boundary between the mundane world and the world beyond the mundane. The old scholars at Mt. Halla entered the gate and met Shinseon, carving the word or picture of Bangseonmun, Whanseonmun, Wuseondae or Deungyounggu so as to structure the enchanting image on Bangseonmun. It is the poetic expression of the taste for the arts, breaking from the troublesome mundane world and riding the white deer to become the Shinseon, the desire for the ideal world in Taoism, and the identity of four famous scenic spots of Bangseonmun. Besides its enchanting meaning and the locational value of Bangseonmun, geological features of the valley and river and ecological value prove its unique value as a natural scenic beauty. Not to mention the locational identity and enchanting meaning of the poets carved in Meeaegak of Bangseonmun and the scenic view of 'Youngguchunhwa' as the subject of 10 famous scenes of Youngju, it is the place for communing with nature with the natural beauty of Bangseonmun Valley. As the cultural place for being together with Jeju people, it simultaneously shows the typical model as a scenic spot in our living. Viewing the scenic value and standard from the aspect of the Cultural Properties Protection Law, Bangseonmun Valley in Jeju must be the typical place and space that meet the requirements to become scenic sites.

Jeongun(丁芸) Lee, Young-do (李永道), who is deemed a representative female poet of Korea, began her literary career in May, 1946 when she published in a publication called "Bamboo Sprout, (죽순)". Her Korean identity, which was formed through her Confucius upbringing as well as traditional value system of her family, had a strong presence in her work, and she remained a quintessential figure in Korea's female sijo poet circle for 30 years until her passing in 1976. Despite the highly acclaimed talent and her noble aspirations, it is undeniable that her works did not receive fair assessment due to her private life. Against this backdrop, it is necessary to deeply inquire the literary values and beauty of Young-do Lee's sijo. As mentioned, Young-do Lee is a solidly established figure in Korea's modern poetry. The following illustrates the spirit and the world of her poetry. First, Young-do Lee lived through turbulent times and it was her country that served as the source of her sijo work. Assessing the multitude of dramatic historical events such as Japanese colonization, 8.15 Liberation of Korea, division of the nation, 6.25 Korean war, 4.19 Revolution, 5.16 military coup, it is natural that patriotism was strongly present in her work who was one of the intellectuals at the time. Second, Young-do Lee is a poet who had experienced more pain than others in terms of the turbulence of the time. Her Korean identity, which was formed through her Confucius upbringing as well as traditional value system of her family, had a strong presence in her work. Third, Jeongun Lee, Young-do is a poet of longing. The abundance and richness of her emotions were fortified through the relationship with another poet, Chihwan Yu. Fourth, Young-do Lee is a poet opened up new horizons for the modennization. The transparency of image reflected in her work and the elaborate nature of her language are outstanding. In summary, Young-do Lee was a true artist, who has a strong presence in Korea's modern poetry society, and who was a poet of patriotism, poet who suffered the turbulence of the times, and a poet of longing.

Due to the prolonged COVID-19 pandemic, the frequency of people who are tired of living indoors visiting nearby mountains and national parks to relieve depression and lethargy has exploded. There is a place where thousands of people who came out of nature stop walking and breathe and rest, that is the mineral spring. Even in mountains or national parks, there are about 600 mineral springs that can be found occasionally in neighboring parks or trails in the metropolitan area. However, due to irregular and manual water quality tests, people drink mineral water without knowing the test results in real time. Therefore, in this study, we intend to develop a model that can predict the quality of the spring water in real time by exploring the factors affecting the quality of the spring water and collecting data scattered in various places. After limiting the regions to Seoul and Gyeonggi-do due to the limitations of data collection, we obtained data on water quality tests from 2015 to 2020 for about 300 mineral springs in 18 cities where data management is well performed. A total of 10 factors were finally selected after two rounds of review among various factors that are considered to affect the suitability of the mineral spring water quality. Using AutoML, an automated machine learning technology that has recently been attracting attention, we derived the top 5 models based on prediction performance among about 20 machine learning methods. Among them, the catboost model has the highest performance with a prediction classification accuracy of 75.26%. In addition, as a result of examining the absolute influence of the variables used in the analysis through the SHAP method on the prediction, the most important factor was whether or not a water quality test was judged nonconforming in the previous water quality test. It was confirmed that the temperature on the day of the inspection and the altitude of the mineral spring had an influence on whether the water quality was unsuitable.

Swans are representative migratory birds that spend winter in East Asia, and have long been considered rare birds. In particular, they were regarded as king of Japan. The process of designating a natural monument in Hapcheon Swan Sanctuary is an interesting story. In this study, the designation and release process of Hapcheon Swan Sancturay ((Bakgok-ji, Yongju-myeon 龍州面 朴谷池), (Jeongyang-ji, Daeyang-myeon 大陽面 正陽池), Gaho, Cheongdeok-myeon 淸德面 嘉湖)) Natural Monument, was examined. These places were designated as a natural monument on August 27, 1934, during the Japanese colonial period, and was lifted on August 14, 1973, after the Cultural Protection Act was enacted after liberation. From the beginning of the new year in 1929, the Japanese Government-General of Korea (朝鮮總督府) decided to capture swans alive to give to the king of Japan. An official of the Japanese Government-General of Korea (統監) decided to offer swans to the king during his New Year's greeting visit. The department in charge of capturing swans was the Gyeongsangnam-do Provincial Police Department, and the execution was the police station of each county (郡). The reason is believed to be that it is easy to forcibly mobilize, control, or urge people, and the capture activity had to be completed as soon as possible. A total of three swans were captured in Hapcheon-gun from January 12 to 14, 1929. At that time, various newspapers published related information. Based on these facts and experiences, it is estimated that the Hapcheon area was selected when designating a natural monument in 1934. Hapcheon Swan Sancturay, Natural Monument lost its function due to excessive human interference of various developments, illegal capture, and use of poison to catch swans. Their number has also significantly decreased. It was thus removed from the natural monument in 1973. One of the three swan sanctuaries (Gaho 嘉湖) has been completely reclaimed, one (Bakgok-ji 朴谷池) has almost no migratory birds due to the conversion of wetlands, and one (Jeongyang-ji 正陽池) has swans flying back. In the case of Jeongyangji (正陽池), It is an encouraging sign that many swans fly as the surrounding environment and growing conditions change. This phenomenon is interpreted to mean that nature and climate are recovering and healing.

This paper aims to review all landscaping elements of Donggwoldo by building and identify the palatial garden landscaping characteristics and landscaping methods in a bid to explore landscaping methods applicable for modern-time gardens of Korea through Succession of Tradition. The research methodology was adopted by which the palatial gardens appearing in Donggwoldo were observed according to garden elements to identify their characteristics. Garden elements in Donggwoldo include oddly shaped stones, ponds, buildings and Madang, borders and areas, and trees. Their characteristics were analyzed, and as a result they are outlined as follows. Location : Buildings in Donggwoldo were located in the optimal areas within the Myungdang (the best location), with the building sites being created by transforming the natural topography positively according to the existing topography and uses. Tree planting : The construction of the buildings involved using the existing trees. There were no specific principle and method of planting trees, and no specific criteria for choosing the kind of tree. Symmetrical planting was adopted and its is considered embracing the viewpoint of making gardens based on the expression of Yin and Yang. Strongly symbolical kinds of trees were also adopted. Bangji : it takes a nearly circular shape in palatial gardens, and such shapes represent conceptual and abstract symbols. They were also frequently used as the place of public entertainment. Pavilions : they did not take a certain standard shape. They had diverse shapes, including a triangle, square, pentagon, hexagon, and octagon and cross. Oddly shaped stones : Oddly shapes stones and stone cases were deployed mainly near the bedroom and the crow prince's residence and in the rear garden. Hwagye : it appeared mainly in the back of the bedroom, the crown prince's residence, the princess's residence, and other women's quarters. Chwibyeong : it was installed for the purpose of drawing the natural energy like a natural inlet instead of being the nature-dividing wall. Korea's garden composition method was very different from the Western and Chinese method. Overall, Chosun palatial garden style was characterized by strict and Confucian features, while the garden construction method adopted the Taoism thought. Yet, the gardens had a carefree aspect.
