In modern society, the paradigm of terrorism is shifting to the form of soft targets focusing on an unspecified number of people, which is different from previous terrorist tendencies, and frequent attacks using chemicals. Therefore, this study analyzed the evacuation environment and characteristics, manual analysis of a terror response manual, and the domestic chemical management status of multi-use facilities, and proposed the following management measures for chemical terror prevention in multi-use facilities. First, a multi-use facility guideline for prompt onsite response is proposed. Second, an improvement plan is suggested through the analysis of the manual for counter terrorism. Third, integrated management is proposed through the selection of chemicals available for terrorism. Through this, it is expected that an additional improvement plan will be prepared for countermeasures against chemical terrorism in multi-use facilities. In the future, it will be necessary to analyze the problems through cases of foreign countries and take customized countermeasures.

To restore urban water cycle, it is necessary to improve domestic laws and regulations related to LID(Low Impact Development), which has been successfully applied to foreign countries. Thus, this study has intended to evaluate domestic legal systems related to space and environmental planning and to suggest directions to improve laws and regulations related to space and environmental planning toward extended application of LID in Korea. To reach this goal, this study has analyze the legal and institutional status of the foreign countries where LID has currently been applied, to derive the factors that laws and institutions are required to support LID based on the above analysis, to evaluate domestic laws and regulations related to space and environmental planning, and to suggest directions to improve the laws and regulations. After the evaluation, this study has found the following results. First, it was found that the concept and basic principles of LID and LID planning and associated methods were no longer mirrored in the space planning-related laws and regulations. However, these problems are not confined to LID, and result from thefailurein applying environmental planning to space planning overall. Second, it was revealed that the environmental planning-related laws and regulations defined the terminologies and targets of LID and suggested different measures to improve LID-related policies differently depending on the backgrounds ofenforcing thelaws and regulations and on environmental properties. Finally, this study has suggested the directions to improve laws and regulations related to space and environmental planning as follows. First, it is necessary to enact a law to support the extended application of LID. Second, the law to be enacted should be connected to laws, enforcement ordinances and regulations, and guidelines related to space planning. Third, environmental benefits provided by both structural and non-structural techniques of LID should be quantitatively measured.

To minimize the damage from chemical accidents, a risk management plan (RMP) has been implemented since 2015. According to this regulation, operators who handle more than the designated quantity of the accident preparedness chemicals should provide emergency response information to the public within the affected areas of accidents. The information, including chemicals, affected areas and evacuation instructions should be provided to the public in advance so that they can evacuate immediately in the event of a chemical accident. Currently, the information notification can be provided in various methods by being registered in the notification system, sent with written documents or delivered directly to the public. To examine the status of the operation method, this study analyzed similar cases overseas, investigated the degree of awareness of providing information through the number of the annual visitor of the Information Provision System, and obtained survey results from some residents. This current operation method are problems because the public, who do not have sufficient information about chemicals, do not understand the emergency information properly or it is difficult to recognize where the residents should find this information because of the convenient operation based on the information provider. In this study, measures were proposed to minimize the damage by making it easier for the public to understand the emergency information and the information communicated appropriately in advance by dividing them into an information providing method and post management.

In contrast to standard train tracks, tramlines are often set along public roads, with trams running among pedestrians and other vehicles. In some cities and towns, trams and buses share the same routes and stations. Under the current investment appraisal system, trams are classified into light rail when predicting traffic demand and calculating benefits, but in the case of non-capital areas, it is notable that the origin-destination and transit lines of buses are not provided in the Korea Transport Database distribution data. Due to this problem, it is difficult to reflect proper mode changing behaviors between route buses and trams. This study examines the impact on tramlines of bus routes that are not currently considered in non-capital areas. Following an analysis of the effect of tram projects according to whether bus routes are considered or not, an improvement in methodology is proposed. Through this study, it is expected that the investment appraisal system for the planning of new tramlines will be improved in the future.

This study presents the current status of DECOVALEX-2023 project Task G and our research results so far. Task G, named 'Safety ImplicAtions of Fluid Flow, Shear, Thermal and Reaction Processes within Crystalline Rock Fracture NETworks (SAFENET)' aims at developing a numerical method to simulate the fracture creation and propagation, and the coupled thermohydro-mechanical processes in fracture in crystalline rocks. The first research step of Task G is a benchmark simulation, which is designed for research teams to make their modelling codes more robust and verify whether the models can represent an analytical solution for displacements of a single rock fracture. We reproduced the mechanical behavior of rock and embedded single fracture using a three-dimensional grain-based distinct element model for the simulations. In this method, the structure of the rock was represented by an assembly of rigid tetrahedral grains moving independently of each other, and the mechanical interactions at the grains and their contacts were calculated using 3DEC. The simulation results revealed that the stresses induced along the embedded fracture in the model were relatively low compared to those calculated by stress analysis due to stress redistribution and constrained fracture displacements. The fracture normal and shear displacements of the numerical model showed good agreement with the analytical solutions. The numerical model will be enhanced by continuing collaboration and interaction with other research teams of DECOVALEX-2023 Task G and validated using various experiments in a further study.

In the era of Corona, companion animals provide a lot of comfort to people, and the Pet Pam group, who thinks of companion animals as family members, has appeared. There is also the Pet Pour phenomenon, in which young consumers spend less on their pets and spend on their companion animals. Despite these changes in the times, pet products, including pet food, are still highly dependent on imports. In addition, since domestic standards for cosmetics and supplies for companion animals have not been established, they rely only on cosmetic safety standards and regulations. In addition, the terminology for domestic pet cosmetics has not been established yet. Currently, only the Animal Protection Act related to companion animals has been amended in the domestic law, but in the case of Japan, the Companion Animal Feed Safety Act came into effect in June 2009. In the United States, the federal Food, Drug, and Cosmetic Control Act covers pet cosmetics and supplies. Germany, which has strong animal protection laws, has various national regulations on food and feed, and detailed national regulations are also provided on the website of the Food Safety Administration. National policies and environments should be established to manage and develop the companion animal industry in Korea as in such a country, and it is considered essential for the development of companion animal cosmetics and various companion animal industries.

World-widely, there has never been a greater need for people to access high-quality expertise about the effective and safe use of medications. Therefore, the profession of pharmacy should meet these needs of the times, as the demographic shifts have led to a situation where older adults now outnumber children, and polypharmacy is also a commonplace. However, the reimbursement system covered by the National Health Insurance (NHI) in Korea is still limited to the traditional dispensing and compounding role of pharmacist. To provide a take-home message to Korean pharmacy reimbursement system, we aimed to review and analyze the international trends in pharmacy remuneration systems. This is a comparative study between Korea, Japan, the United Kingdom, and the United States. Comparison was conducted by reviewing each country's policy and enforcement programs, as well as the related literature. Japan, the UK and the US systems remunerate diverse patient-centered pharmaceutical care services. The Korean pharmacy service fee is, however, narrowly focused on the traditional product-oriented pharmacy services. This study discussed the future direction of improving pharmacist reimbursement systems in Korea, by expanding professional pharmacy service coverage and diversifying fee schedule.

In this study, a state-of-the-art review on urban inundation simulation technology was presented summarizing major achievements and limitations, and future research recommendations and challenges. More than 160 papers published in major domestic academic journals since the 2000s were analyzed. After analyzing the core themes and contents of the papers, the status of technological development was reviewed according to simulation methodologies such as physically-based and data-driven approaches. In addition, research trends for application purposes and advances in overseas and related fields were analyzed. Since more than 60% of urban inundation research used Storm Water Management Model (SWMM), developing new modeling techniques for detailed physical processes of dual drainage was encouraged. Data-based approaches have become a new status quo in urban inundation modeling. However, given that hydrological extreme data is rare, balanced research development of data and physically-based approaches was recommended. Urban inundation analysis technology, actively combined with new technologies in other fields such as artificial intelligence, IoT, and metaverse, would require continuous support from society and holistic approaches to solve challenges from climate risk and reduce disaster damage.

Recently, in relation to climate change, many studies have been conducted to predict the potential habitat area and distribution range of tilapia and the suitability of habitat for each species. Most tilapia are tropical fish that cannot survive at water temperatures below 10 to 12℃, although some tilapia can survive at 6 to 8℃. This study predicted habitable areas and the possibility of spreading of habitat ranges of tilapia (Oreochromis niloticus and Oreochromis aureus) known to inhabit domestic streams. Due to climate change, it was found that habitats in the Geum River, Mangyeong River, Dongjin River, Seomjin River, Taehwa River, Hyeongsan River, and the flowing in East Sea were possible by 2050. In addition, it was confirmed that tilapia could inhabit the preferred lentic ecosystem such as Tamjin Lake, Naju Lake, Juam Lake, Sangsa Lake, Jinyang Lake, Junam Reservoir, and Hoedong Reservoir. In particular, in the case of tilapia, which lives in tributaries of the Geumho River, Dalseo Stream, and the Nakdong River, its range of habitat is expected to expand to the middle and lower of the Nakdong River system. Therefore, it is judged that it is necessary to prepare physical and institutional management measures to prevent the spread of the local population where tilapia currently inhabits and to prevent introduction to new habitats.
