As information is recognized as a core competency of organizations, organizations are increasingly investing in policies and technologies for information security(IS). Recently, as information exposure accidents by people have occurred continuously, interest in IS behaviors of organization insiders is increasing. This study aims to confirm the effect of the IS environment and support structure established by the organization on the intention of individuals to comply with IS. We conducted a survey of employees in organizations with IS policies and tested the hypothesis using the structural equation of AMOS 22.0 and Process 3.1 using 421 samples. As a result of the analysis, authentic leadership and justice climate, which are factors that build an IS environment, and communication and feedback, which are factors supporting IS compliance, have a positive effect on employees' compliance intention. In addition, authentic leadership, punishment, communication, and feedback were found to reinforce the positive impact of IS justice climate. As the study suggested the overall structural design direction to be pursued to reinforce insider's IS behavior, and the results help to achieve the IS goal.

The frequency of flash floods in mountainous areas is increasing due to the abnormal weather that occurs increasingly in the recent, and it causes human and material damages is increasing. Various plans for disaster mitigation have been established, but artificial plans such as raising embankment and dredging operation are inappropriate for valleys and rivers in national parks that prioritize nature protection. In this study, flood risk assessment was conducted for Gyeryongsan National Park in Korea using the WMS (Watershed Modeling System)which is rainfall runoff model for valleys and rivers in the catchment. As the result, it was simulated that it is flooding in three sub-catchments (Jusukgol, Sutonggol, Dinghaksa) of a total in Gyeryongsan National Park when rainfall over the 50 years return period occurs, and it was confirmed that the risk of trails and facilities what visitors are using was high. The risk of trails in national parks was quantitatively presented through the results of this study, and we intend to present the safe management guidelines of national parks in the future.

In recent years, the world's free trade system has been severely damaged by a series of protectionist measures in the United States and anti-globalization practices such as Brexit. Against this background, RCEP, the world's largest trade agreement, was officially signed on November 15, 2021. The RCEP provided a good working basis for the establishment of a Korea, China, and Japan free trade zone. First, this paper describes the current status of Korea-China-Japan trade cooperation and the current status of the trilateral telecommunication industry. Second, this paper simulates the changes in the overall economy of China, Japan, and Korea when tariffs are reduced to 0%, 5%, and 10%, respectively, after the establishment of a free trade zone using the 8th edition GTAP database. Then, using the simulated data changes and using the 2019 data as a benchmark, we calculated the changes in the RCA index for the three countries' telecommunications industries for the three tax rates. In the end, it is concluded that the economies of the three countries will grow to different levels in many ways when the Korea, China, and Japan free trade zone is established. Japan's telecommunications industry will not be significantly affected, Korea will grow significantly with higher tax rates and China will grow significantly with lower tax rates.

Purpose: The effectiveness of the transport vehicle management system of the Chemical Substances Control Act will be studies and used as basic data for future system improvement plans. Method: After the enforcement of the Chemical Substances Control Act, the effectiveness for the transport vehicle management system was studies by comparing the transport plan, guidance and inspection status, safety training completion management, ect., and the reduction rate of chemical accidents. Results: The average number of chemical accidents in transport vehicles nationwide is 20 each year. And It is decreasing with the stabilization of the Chemical Substances Control Act('15.1.1). The first reason for the decrease in chemical accidents is the increase in submission of transport plans. Second, as the guidance and inspection rate increased every year, the shipper company's management of transport companies was naturally strengthened. Finally, it is judged that chemical accident caused by transport vehicles decrease through safety education. Conclusion: The current tranport vehicle management system of the Chemical Substances Control Act is effective. However, further research is needed to improve the practical and efficient transport vehicle management system.

Since the advent of Bitcoin, various virtual assets have been actively traded through virtual asset services of virtual asset exchanges. Recently, security accidents have frequently occurred in virtual asset exchanges, so the government is obligated to obtain information security management system (ISMS) certification to strengthen information protection of virtual asset exchanges, and 56 additional specialized items have been established. In this paper, we compared the domain importance of ISMS and CryptoCurrency Security Standard (CCSS) which is a set of requirements for all information systems that make use of cryptocurrencies, and analyzed the results after mapping them to gain insight into the characteristics of each certification system. Improvements for 4 items of High Level were derived by classifying the priorities for improvement items into 3 stages: High, Medium, and Low. These results can provide priority for virtual asset and information system security, support method and systematic decision-making on improvement of certified items, and contribute to vitalization of virtual asset transactions by enhancing the reliability and safety of virtual asset services.

The rare and endangered plants in Naesorak area were investigated for four months during May to August in 1997, and the results were summarized as 35 taxa which is classified as 19 families, 32 species, and 3 varieties. At the level of families, 19 families such as Pinaceae(1 species), Taxaceae(1 species), Cupressaceae(1 species and 1 variety), Liliaceae(5 species and 1 variety), Aristolochiaceae(2 species), Ranunculaceae(4 species), Berberidaceae(1 species), Saxifragaceae(2 species), Rosaceae(1 species), Oleaceae(2 species and 1 variety), Solanaceae(1 species), Scrophulariaceae(1 species), Valerianaceae(1 species), Campanulaceae(1species), and Compositae(1 species) were recorded. The most of the habitats of the species was easily found along the major mountain trails, and a kind of destructions of these plants by human interferences is due to the fact that the illegal collections for food and medicine are occurred. Those species of Taxus caespitosa, Rhododendron aureum, Vaccinium bracteatum, Allium victoralis var. platyphullum and Leontice microryncha has a few individuals in habitats and also shows the unfavorable growing state, so the intensive and continuous habitat management of the habitats were inevitably dimanded.

In recent decades, the world has entered a new era in terms of the number and variety of biological invasions, due to economic progress and transportation efficiency. Biological invasion is becoming more likely as demand for foreign fresh foods and decorative goods grows. Alien species continue to infiltrate Korea in a variety of ways, and disturb on the insect fauna of Korea. The goal of plant quarantine is to decrease the economic impact of alien pests on the agriculture and forestry industries. In this study, we focused on insects found in imported cut flowers from 1996 to 2020 using pest information system. Overall, 147,160 cut flowers (159 items) were imported into Korea from 69 countries during this time period. Throughout this time, 467 species of insects were found in all imported cut flowers to Korea, total 13,757 detections. They were classified as provisional regulated pests in 273 species, quarantine managed pests in 78 species, and non-quarantine pests in 118 species. Thysanoptera and Hemiptera had the largest number of alien insect detections (more than 80% of the alien insects) among the nine orders. The outcomes of this study have highlighted the need for ongoing inspection activities targeted at preventing quarantine alien pests from entering or incursion in Korea.

In this study, the recognition of child abuse and neglect (CAN) and reporting attitudes of general dentists and pediatric dentists in Korea were estimated. A survey was conducted among dentists working at clinics or university hospitals, including interns and residents at dental hospital training institutions. The questionnaire, consisting of 32 questions and detailed questions, subdivided into 'general characteristics of respondents', 'CAN', 'CAN report', 'laws to CAN', 'countermeasures against CAN'. The survey was conducted using a messenger, and 176 respondents' answers were analyzed. The recognition of CAN showed high scores in the order of physical abuse, neglect, and emotional abuse. The positive attitude toward reporting CAN had a higher score than the negative attitude. Of the total respondents, 19 said they reported child abuse, and 18 said they were suspected of child abuse but hesitated to report it. Among the laws related to CAN, the protection measures for CAN reporters and the protocol for CAN showed low awareness. Since then, they have wanted to know how to find abused children and how to deal with them in education. This study is expected to be used as data to improve dentists' awareness and consciousness of CAN in the future.

The global outbreak of COVID-19 has underscored the pressing need for robust infection control practices in pulmonary function laboratories (PFL). However, the existing guidelines and regulatory frameworks provided by relevant authorities in the country have revealed certain deficiencies in effectively addressing this significant public health crisis. This study surveyed the infection control regulations, disposable item usage, ventilation facilities, spatial separation, and the configuration of entrance doors in 51 domestic hospital facilities from Oct 1, 2021, to Nov 2, 2021. The survey findings revealed that while there was a relatively satisfactory adherence to airborne, droplet, and contact precautions with adequate awareness and utilization of personal protective equipment, the environmental disinfection practices exhibited a suboptimal performance rate of 39.22% per patient. Depending on the specific survey domains, substantial variations were observed in the utilization of disposable items (81.05%), ventilation systems (45.75%), dedicated testing spaces (80.39%), separation of administrative areas (15.69%), and the installation of automated doors (19.61%). This study not only highlights the paramount importance of infection control in PFLs within domestic medical institutions but also provides foundational data for developing and enhancing standardized guidelines that align with international benchmarks for infection control in these settings.
