The Pacific Island Forum that consists of 14 island countries in the South Pacific has long been the focus of keen attention from East Asian countries such as South Korea, Japan and China. The South Pacific area was controlled by Japan right after the First World War. The League of Nations bestowed the right of trusteeship over the region to Japan, one of the victors in the war. However, the U.S. considered the area indispensible for its security interests in the Pacific after victory in the Second World War. With the end of Cold War period, the region again began to gain the competitive attention of Japan, China and Korea. Japan has made efforts to give economic assistance to this region by holding the Japan-Pacific Islands summit every three years. In addition, Japan is promoting a security engagement with this region by dispatching Self Defense Forces with the aim of initiating construction and development projects. In response to Japan's active involvement in the region, China also began to convene a summit meeting with these countries in 2006, making pledges of economic assistance. Furthermore, Chinese civilian companies struck deals of investment with municipal institutions in the region with a view to enhancing China's influence in the region. Japan's and China's active engagement in the region has galvanized South Korea to craft a more effective strategic approach to the region.

Mineral compositions in various ginseng, which was grown in different region, different age, were analyzed by atomic absorption spectrophotometer. $Mn^{++}$ content in ginseng of five years old was four times higher than that of two years old, suggesting that the amount of $Mn^{++}$ would be increased as they are cultivated. The content of phosphate in the various ginseng did not show much difference, whereas that of $Ca^{++},\;Mn^{++}$ did. Korean red ginseng revealed much higher in $Mn^{++}$ content than that of others investigated. When the amount N was compared, San Chi, Chinese ginseng was significantly lowered. Korean red ginseng of 100g contains highest phosphate ion of 328.3mg.

Concerns on the air pollution problem caused by ambient fine particles have become a big social issue in Korea. Important factors that should be addressed to develop effective and efficient air quality management policy, especially, against fine particles are discussed and research and policy directions to address these factors are suggested. It is suggested that two factors are in high priority; one is scientific understanding of the major formation mechanisms of fine particles and the other is the process of policy decision and implementation. For the scientific understanding, smog chamber measurement, intensive field study, and chemical transport model development that can simulate the characteristics of Northeast Asia are considered to be important. For the policy directions, priority setting of the proposed policies and development and implement of effective communication sytem are considered to be important.

Biodiversity informatics applies information technology methods in organizing, accessing, visualizing, and analyzing primary biodiversity data and quantitative data management through the scientific names of accepted names and synonyms. We reviewed the GBIF data published by China, Japan, Taiwan, and internal institutes, such as NIBR, NIE, and KNA of the Republic of Korea, and assessed data in diverse aspects of data quality using BRAHMS software. Most data from four Asian countries have quality problems with the lack of data consistency and missing information on georeferenced data, collectors, collection date, and place names (gazetteers) or other invalid data forms. The major problem is that biodiversity management institutions in East Asia are using unstructured databases and simple spreadsheet-type data. Owing to the nature of the biodiversity information, if data relationships are not structured, it would be impossible to secure the data integrity of scientific names, human names, geographical names, literature, and ecological information. For data quality, it is essential to build data integrity for database management and training systems for taxonomists who are continuous data managers to correct errors. Thus, publishers in East Asia play an essential role not only in using specialized software to manage biodiversity data but also in developing structured databases and ensuring their integration and value within biodiversity publishing platforms.

After its experiment involving the exploding of a satellite in space in 2007, China proudly aired news on TV and ran articles in newspapers. However, the event was internationally criticized and drew widespread attention. Many countries denounced the explosion by pointing out that it could be part of the nation's plan to expand its military power to space or that it could pose a danger to the peaceful use of space. However, there is no talk of whether the experiment that produced a huge amount of space debris could have violated an international law, namely the Outer Space Treaty. Although space garbage has been said to be a serious problem, the amount is still on the increase. If we continue to launch new space launch vehicles into orbit at this rate, we will not be able to use it anytime soon like we do today. As the commercial use of space is likely to increase, the situation will certainly get worse. The international community is fully aware of the seriousness of the problem and working together to reduce the amount of space garbage. However, despite the fact that the United States and Soviet Union's ASAT(Anti-Satellite) programs have been implemented for a long time, there have been no complaints about them in terms of military expansion or breach of the Outer Space Treaty. Also, the recent Chinese test is largely viewed to be in accordance with international law. A lot of research has been undertaken with regard to the problem of space garbage. Now people's awareness of dangers being posed has been fully raised. Under the circumstances, the dismissing of China's satellite smashing, leaving a big mess in its wake, as nothing more than an experiment, is a red flag to, if not many, at least some people. By means of this thesis, I would like to review whether the Chinese test has violated an international space law. This thesis presents an overview of the issues surrounding the event and examines the possibility of violating the Outer Space Treaty, formally the Treaty on Principle Governing the Activities of States in the Exploration and Use of Outer Space, Including the Moon and Other Celestial Bodies. After the China test, the UN Scientific and Technical Subcommittee first adopted space debris mitigation guidelines, I'll introduce the content of the guidelines and discuss the characteristics of the guidelines and what can be done to address the issue.

Chemical and Pb isotope analysis were performed in order to determine the origin of bronze artefacts excavated from the Inyongsaji site in South Korea. The result of ICP-MS shows that they are tin bronzes in which lead was not intentionally added during production. Pb isotope data analyzed by TIMS are plotted in the southern region of Korea and China of the distribution map drawn by Mabuchi(1985). On the other hand, the identical isotope data are plotted in the Taebaek basin and the Olcheon metamorphic belt correspondent to zone2 and zone3 respectively. It is believed that the isotope data on the tin bronzes which have very low lead content can be used to trace the origin of copper ore rather than those of either lead or tin ore. Pb istope analysis allows diverse interpretation as it can be applied to any object containing trace amounts of lead. In addition, accumulation of isotope data as well as further studies will improve reliability of the provenance studies.

This study developed a species identification method for the salted opossum shrimp of Acetes japonicus, A. chinensis (Korea, China), A. indicus (I, II), and Palaemon gravieri based on PCR-RFLP markers. Genomic DNA was extracted from the salted opossum shrimp. The COI gene was used to amplify 519 base pairs (bp) using specific primers. The amplified products were digested by Acc I and Hinf I, and the DNA fragments were separated by automated electrophoresis for RFLP analysis. When the amplified DNA product (519 bp) was digested with Acc I, A. japonicus, A. chinensis (Korea), and A. indius (II) showed two fragments, whereas a single band of 519 bp was detected in A. chinensis (China) and A. indius (I). Also, in the RFLP patterns digested by Hinf I, A. chinensis (Korea) and A. chinensis (China) showed a single band of 519 bp, while two fragments were observed in A. japonicus and A. indius (I) and four fragments in A. indius (II). The PCR amplicon of P. gravieri was digested by Acc I into 3 bands of 271, 202, and 46 bp and by Hinf I into a single band of 519 bp. Therefore, salted opossum shrimp-specific RFLP markers showing distinct differences between four species and two sub-species by PCR-RFLP analysis. Thus, the PCR-RFLP markers developed in this study are a good method for identifying the six types of salted opossum shrimp.

In today's rapidly developing technology, the traditional exhibition format of museums can no longer meet social needs. By analyzing the advantages and key technologies of extended reality technologies such as virtual reality, augmented reality, and hybrid reality, the museum XR exhibition interaction scheme is analyzed. Come to Discovery Museum. In this regard, this study first delves into the concept of XR technology, the concept and influencing factors of tourist experience, and the relationship between the application of XR technology and tourist experience through theoretical investigation. On this basis, representative paleontological museums in China and South Korea were selected, and the actual experience of visitors at the exhibition site and the application of XR technology were investigated through examples. Research has shown that the use of augmented reality technology can achieve seamless integration of virtual and real worlds in paleontological museums, extend viewing space, expand cultural heritage connotations, and revitalize cultural heritage. It provides visitors with a deeper interactive experience, enhances immersion and enriches display methods, making this type of museum more attractive. On this basis, XR technology helps museums achieve Digital transformation, and makes them have the advantages of sustainable development.
