The areas be affected maritime police authority of the Republic of Korea, are largely classified as inland waters, territorial waters, exclusive economic zone and continental shelf(hereinafter referred to as "domestic sea area") and high seas. Of these, the maritime police authority in domestic sea area follows a municipal law that accommodates the United Nations Convention on the Law of the Sea(UNCLOS). In addition, this Convention shall apply on the high seas. Meanwhile, on the high seas, foreign vessels other than domestic vessels are allowed to be subject to limited jurisdiction only for the anti-mankind criminal acts, such as piracy etc. this is in accordance with the principle of "Freedom of the high seas" and "maritime flag state," under this Convention. However, the illegal acts of foreign vessels that threaten the security of coastal states and the safety of ships on the high seas can cause many types of crimes other than anti-mankind criminal acts, and the jurisdiction of the coastal states exercised may lead to conflicts between countries. Therefore, this article would like to suggest a plan for institutional improvement to maintain international maritime order on the high seas and secure maritime police authority in coastal states.

With the increase of metal usage in various industries, metal pollution and ecological toxicity in the environmental system have become a significant concern. A geo-statistical index has been widely used to determine contamination level with normalization through a background value. In this study, geo-statistical indexes such as an enrichment factor, accumulation index, and potential ecological risk index were used to assess metal pollution in soil at locations associated with shipbuilding manufacturing industries. Metal contamination, especially of Cu and Pb, was observed in some samples located closer to manufacturing sites. Enrichment factor and accumulation (IGEO) values were indicative of concerning levels of soil contamination in specific samples, and the soil contamination could be induced by anthropogenic sources. In further study, after more detailed sampling for soil and potential pollution sources, high interpretation techniques such as Pb isotope analysis and X-ray analysis will be needed to investigate source identification.

In 2001, about 20 years after the introduction of the standard buoys, the natural environment and maritime traffic flow changes in the waters near Korea and the necessity of improvement of the AtoN (Aids to Navigation) maintenance was suggested. The IALA provides guidelines for maintenance and management of AtoN, and Korea provides guidelines for the management and operation of standard buoys by means of the Enforcement on the AtoN laws. The objective of this study was to investigate the installation status and the repair status of the standard type buoys by sea area in order to improve the management and operation of the steel standard buoys. In addition, a survey was conducted on the improvement of the steel buoy fouling and the improvement of the lifting inspection cycle towards on the AtoN managers and producers of the representative authority by sea area. In the case of LL-26 (M) buoy type, the standard type buoy installation status of Korea in 2017 was 57.1%, and the LL-26 (M) type was 58.9% showing the highest repair rate. According to the results of the survey on buoys fouling, 51.2% were caused by the attachment of shellfish, and 43.2% were caused by bird feces. The results of the survey on the improvement of the regular buoy inspection cycle showed that the measures are to maintain the current inspection period of 2 years regardless of the characteristics of the sea area (water depth, inside and outside port, buoy size, etc.).

This study has as a object to investigate some various meanings of the discourses of postdevelopment of Arturo Escobar with the respect of the social movements of the indigenous and the afro-colombians in the area of the Pacific Coast of Colombia. The ideological lines of Escobar go around the group of critical discourse Modernity/(De)coloniality whose thesis lies on revealing the coloniality as principal elements of the modernity from the XVI century until now culminating in the neoliberal globalization. In another words, they try to seek for the alternative globalization based on the autonomy of the people who has been alienated for long time as 'others' by the eurocentrism of the power and the knowledge and on the equality of the cultural differences o the cosmovisions in Latin America. Escobar concentrates on the fact that the neoliberal regime would turn the nature into the environment considered as the resources for example the traditional knowledges of biodiversity of the indigenous as the capital of the pharmaceutical companies through the patents. However, the indigenous and the afro-colombians have fought fiercely to have them be maintained as a colective right of the possession not only to guard the economic interests but also their proper cultural traditions and the way of life based on the social solidarity of reciprocal care instead of the occidental individualism. This corresponds not only to the social relations but between the nature and the human society. And so, Arturo Escobar interprets these movements not only to defend the places but to express the cosmovisions of Postdevelopment further more the modern paradigm of nation-state.

The position of existing patrol ships has been decided according to subjective judgments, not purely by any reasonable or scientific criteria, because of a lack of access to marine accident positions. In this study, the optimal location of patrol ships is quantitatively determined based on historical marine accident data. The study area used included the coastal sea of Pohang in South Korea. In this study, a k-means clustering algorithm was used to derive the location of patrol ships, and then a Voronoi diagram was used to divide the region around each patrol ship. As a result, the average navigation distance for patrol ships was improved by 4.4 nautical miles, and the average arrival time was improved by 13.2 minutes per marine accident. Moreover, if the locations of patrol ships need to be changed flexibly, it will be possible to optimally arrange limited resources using the technique developed in this study to ensure a fast rescue.

The fire detectors used in the engine rooms of ships offer only a slow response to emergencies because smoke or heat must reach detectors installed on ceilings, but the air flow in engine rooms can be very fluid depending on the use of equipment. In order to overcome these disadvantages, much research on video-based fire detection has been conducted in recent years. Video-based fire detection is effective for initial detection of fire because it is not affected by air flow and transmission speed is fast. In this paper, experiments were performed using images of smoke from a smoke generator in an engine room. Data generated using LBP and GLCM operators that extract the textural features of smoke was classified using SVM, which is a machine learning classifier. Even if smoke did not rise to the ceiling, where detectors were installed, smoke detection was confirmed using the image-based technique.

The Maritime Domain Awareness system is a component that is necessary to enhance the awareness of all situations occurring at sea in relation to security, safety, economy, and the environment. To establish a marine situation recognition system that is currently being introduced in major maritime countries after approval by the International Maritime Organization's Maritime Safety Committee in 2010, operational measures should be established. For the purpose of establishing a technological foundation for the efficient construction of a Korean maritime situation recognition system, this study analyzed the status of each system (RADAR, VHF, and V-PASS, etc.) and proposed the application of data and communication standards.

Recently, controversy has been raised over the security and safety of Chinese-made network equipment (Huawei 5G), apps (TikTok, etc.). In particular, according to the results of the Ministry of Defense investigation in 2020, malicious codes were found in CCTVs made in China that were delivered as military surveillance equipment used as a coast guard system, and specific information was remotely transmitted to a Chinese server. The safety issues of these Chinese security products can be questioned as being systematically led by the state rather than by companies or individuals. In this paper, we perform network and process level analysis of 360 Total Security(360 TS), a Chinese antivirus software. In addition, it compares and analyzes the domestic cloud-based vaccine V3 Lite product. Through this, the safety of Chinese security solutions is checked and information leakage and risks are suggested.

Statistical analysis was performed on national forensic autopsy data collected in the Republic of Korea, with the exception of Ulsan, during 2017. A total of 8,777 cases were categorized based on the region; information was provided by the Police Agency and the Coast Guard regarding sex, age, manner of death, and cause of death. Analysis of the manner of death revealed that 3,971 cases (45.2%) were unnatural deaths, 3,679 cases (41.9%) were natural deaths, and 1,127 cases (12.8%) were unknown deaths. Among the unnatural deaths, the majority of the cases (1,740 cases, 43.8%) were accidents, 1,316 cases (33.1%) were suicide, 385 cases (9.7%) were homicide, and 530 cases (13.3%) were undetermined deaths. Among the unnatural deaths, the majority of the cases (1,575 cases, 39.7%) were trauma, followed by 793 cases (20.0%) of poisoning and 689 cases (17.4%) of asphyxia. Falling down was the major cause of death by trauma (737 cases, 46.8%). As a result of the classification of asphyxia based on previous study, strangulation was the major cause, with 538 cases (78.1%). Among the natural deaths, heart disease was the major cause (1,790 cases, 48.7%), followed by vascular disease (697 cases, 18.9%).

The purpose of this study is to examine whether personality and reward affect PSM of new maritime police officer recruits. Results are as follows. First, among the personality factors, the neuroticism sub-factor had significant positive effect on PSM sub-factors favorable perception towards public policy, commitment to public interest, and empathy. Also, the extroversion sub-factor had significant effect only on the self-sacrifice sub-factor of PSM. Second, the reward factor mostly didn't have significant effect on PSM. The internal reward sub-factor had significant effect on the empathy sub-factor of PSM. These results confirm that personality factors have significant impact on public service motivation. This implicates the need for policy improvements to reflect this result, and further empirical studies on the relationship between reward and public service motivation.
