In this study, several important aspects were studied in producing video advertisements based on the lifestyle and SNS status of Generation Z. Generation Z highly values participation and interaction due to the nature of SNS, so SNS advertisements should be produced in a way that induces active interaction with viewers and accepts feedback. Here's a summary of the main parts. It prefers various content formats of Generation Z that consume information. Advertisements should be produced in various formats such as text, images, and videos, and should have flexibility suitable for various platforms. Because each SNS platform has its own characteristics due to platform specialization, this study suggests that advertisements analyze the characteristics of the platform and use the appropriate content strategy for the optimized platform. As an emphasis on value proposition, we propose an advertising format setting to focus on what value the product or brand provides. It is important to clearly emphasize the advantages and intrinsic value of a product or service in video advertising, and in conclusion, we propose to focus on the case of increasing interest by adopting modern and trendy design of storytelling as an attractive and unique design method of aesthetic design and visual effects. Considering these factors comprehensively, the research value of this paper will be able to establish an effective SNS marketing strategy by producing video advertisements that match the lifestyle and SNS usage characteristics of Generation Z.

In medical litigation, there are various cases where a doctor's 'explanation' of a patient becomes problematic. Medical explanations and guidance are required from the doctor, starting from the beginning of diagnosis, through treatment processes such as surgery, when hospitalization is necessary for treatment, during hospitalization, upon discharge, and after discharge. Furthermore, notification from the doctor or medical institution may be requested regarding the economic costs that will be incurred due to medical treatment. South Korea's judiciary has been developing legal principles regarding such doctor's explanations by distinguishing between explanations for obtaining consent for medical treatment and medical explanations related to guidance on patient treatment methods, taking into account related laws such as the stage of treatment and the Medical Service Act. Additionally, the Constitutional Court recently ruled on the non-benefit cost notification system linked to the explanation of economic costs. However, holding a doctor accountable solely because the doctor's explanation was insufficient has aspects that do not correspond to the actual situation in clinical reality, and may have a reflexive disadvantage that results in a decline in legal rights. Therefore, the doctor's explanation needs to be examined from both perspectives: guaranteeing the patient's right to self-determination and protecting his or her right to decision.

In this study, we evaluate the applicability of domestic and international forest fire indices in Korea. To accomplish this objective, we first compare the structures of widely-used forest fire indices worldwide. Then, the application results of these forest fire indices are evaluated by comparing them with the annual and seasonal variations in actual forest fire occurrences in Korea. Finally, we select indices suitable for domestic application and propose directions to improve their appropriate applicabilities. The considered forest fire indices include MI, KBDI, FFWI, and mFFWI developed in the United States, NI, ZhI, and MNI developed in Russia, and DWI developed in Korea. This study considers the East Coast region as a study area, and the number of forest fire occurrences is referenced from the forestry statistics yearbook provided by the Korea Forest Service. As results, first, most forest fire indices do not adequately reproduce the actual annual forest fire occurrences as its variation is so small. However, most indices are found to effectively represent the monthly variations. Based on the correlation analysis between forest fire indices and actual forest fire occurrences, mFFWI, MI, ZhI, and DWI are selected as suitable indices for the East Coast region. However, these indices are still not satisfactory to adequately represent the forest fire occurrences in Korea, suggesting the need for further improvements. Each index has its own different aspects to be improved and, therefore, evaluation of these indices may be available only after further improvements are completed.

Current analysis of air passengers mainly relies on statistical methods, but there are limitations in analyzing detailed aspects such as travel routes, number of regional passengers and airport access times. However, with the advancement of big data technology and revised three data acts, big data-based transportation analysis has become more active. Mobile communication data, which can precisely track the location of mobile phone terminals, can serve as valuable analytical data for transportation analysis. In this paper, we propose a air passenger Origin/Destination (O/D) extraction algorithm based on mobile communication data that overcomes the limitations of existing air transportation user analysis methods. The algorithm involves setting airport signal detection zones at each airport and extracting air passenger based on their base station connection history within these zones. By analyzing the base station connection data along the passenger's origin-destination paths, we estimate the entire travel route. For this paper, we extracted O/D information for both domestic and international air passengers at all domestic airports from January 2019 to December 2020. To compensate for errors caused by mobile communication service provider market shares, we applied a adjustment to correct the travel volume at a nationwide citizen level. Furthermore correlation analysis was performed on O/D data and aviation statistics data for air traffic users based on mobile communication data to verify the extracted data. Through this, there is a difference in the total amount (4.1 for domestic and 4.6 for international), but the correlation is high at 0.99, which is judged to be useful. The proposed algorithm in this paper enables a comprehensive and detailed analysis of air transportation users' travel behavior, regional/age group ratios, and can be utilized in various fields such as formulating airport-related policies and conducting regional market analysis.

In order to know the depletive changes of sulfamethazine residues in senlm and practical organs of rats orally administered with sulfamethazine sodium(SMS), the concentration of sulfamethazine was measured in serum and tissue(kidney, liver, spleen, testis, and skeletal muscle) of rats with using high performance liquid chromatography(HPLC). SMS was orally administrated to sprague-dawley male rats(body weight, 200~300g) with using sonde at the rate of 20mg/100g body weight(recommended therapeutic dose) on once a day for 3 days. There were investigated the depletive changes of the sulfamethazine in serum, kidney, liver, spleen, testis and skeletal muscle of rat at the time 8 hours, 1st, 2nd, 3rd, 4th, 5th and 6th day after administration SMS, respectively. The results obtained were summarized as follows; 1. After oral administration of the SMS, the mean concentrations of sulfamethazine in serum according to the time lapsed were showed 215.53$\pm$42.99ppm at the 8 hours after withdrawal of medicated sulfamethazine. And gradually according to the time lapsed, the concentrations of sulfamethazine residues in serum were significantly (p<.05) decreased 25.87$\pm$5.18ppm at 1st day, 2.30$\pm$0.61ppm at 3rd day and 0.11$\pm$0.02ppm at 6th day respectively. 2. The mean concentrations of sulfamethazine in kidney, liver, spleen, muscle and testis according to the time lapsed after administration SMS were showed 83.82$\pm$12.16, 81.77$\pm$12.88, 36.96$\pm$5.35, 35.96$\pm$TEX>$\pm$1.39 and 27.89$\pm$1.92 ppm at the 8 hours, respectively. And gradually according to the time lapsed, the concentrations of sulfamethazine residues in the each of samples were significantly(p<.05) decreased such as 7.15$\pm$0.26, 5.62$\pm$0.72, 2.43$\pm$0.29, 1.99$\pm$0.14 and 3.11$\pm$0.48 ppm at 1st day, 0.52$\pm$0.04, 1.32$\pm$0.22, 0.13$\pm$0.03, 0.15$\pm$0.06 and 0.26$\pm$0.11ppm at 3rd day, and 0.03$\pm$0.01, 0.11$\pm$0.03, 0.02$\pm$0.01, 0.009$\pm$0.001 and 0.02$\pm$0.01 ppm at 6th day, respectively. 3. After oral administration of the SMS to rats, the residual concentrations of sulfamethazine in skeletal muscle were significantly (p<.05) decreased 35.96$\pm$1.39 to 0.009$\pm$$\pm$0.001 ppm between 8 hours and 6th day, respectively From the 4th day, the residual concentrations of sulfamethazine were showed 0.10$\pm$0.04 ppm below 0.1 ppm at the permitted limit concentration of muscle in Korea.

One of the most fundamental jobs of contemporary government is to look into various ways of providing its citizens with the best service work. This study aims to establish a procedure through which to consign the management of city parks to private companies, thus inviting participation and satisfaction on the part of citizens. In particular, this procedure includes creating a system of selecting private managing companies, for instance, specifying standards of selection and assembling selection committees. The results of this study can be summarized as follows. First, city parks can be managed better by private companies than by local governments in terms of cost cuts, personnel training, business efficiency, and know-how accumulation. The legal background for this is found in central and local legal articles. Second, it is recommended that the selection committee be composed of 6 to 9 members, both insiders and outsiders. In addition to selecting private managing companies for contracting-out, the committee should under take the role of consulting on how to perform and revise selecting standards, so that they can continue to improve these procedures. Third, the decision on private management should be noticed in advance and be made based on standards considering each local government's condition. These standards should consider the aspects of the public good, cost saving, quality of service, managing supervision, and citizen participation. The committee's assessment takes into account both the quality and the quantity of the standards. Fourth, the contracting-out for city park management should follow the order of: announcing consignment and receiving applicants, organizing selection committees and assessing applications, selecting and contracting, midterm evaluation, and re-announcement and re-consignment. To run city parks through the contracting-out is expected to increase the number of park visitors. Additionally, private consignment will involve a participation of diverse citizenship, thus playing an important role in city parks' building of a green-culture community.

It can be said that 'the September 11th Terrorist Attacks' in 2001 were not only the indiscriminate attacks on innocent people but also the whole - political, economical and military - attacks on human life. Also, 'the September 11th Terrorist Attacks' can be regarded as the significant events in the history of world, which were on the peak of the super-terrorism or new-terrorism that had emerged from the 1980s. However, if one would have analysed the developments of terrorism from the 1970s, they could have been foreknown without difficulty. The finding from this study can be summarized as the followings, First, in spite that the USA responsive system against terrorism had been assessed as perfect before 'the September 11th Terrorist Attacks', the fragilities were found in the aspects of the response on the new-terrorism or super-terrorism. The previous responsive system before 'the September 11th Terrorist Attacks' had the following defects as the followings: (1) it was impossible to establish the integrated strategy, because the organizations related to the response against terrorism had not integrated; (2) there were some weakness to collect and diffuse the informations related to terrorism; (3) the security system for the domestic airline service in USA and the responsive system of air defense against terrors on aircraft were very fragile. For these reasons, USA government established the 'Department of Homeland Security' of which the President is the head so that the many organizations related to terrorism were integrated into a single management system. And, it legislated a new act to protect security from terrors, which legalized of the wiretapping in spite of the risk of encroachment upon personal rights, increased the jail terms upon terrorists, froze the bank related to terrorist organization, and could censor e-mails. Second, it seem that Korean responsive system against terrors more fragile than that of USA. One of the reasons is that people have some perception that Korea is a safe zone from terrors, because there were little attacks from international terrorists in Korea. This can be found from the fact that the legal arrangement against terrorism is only the President's instruction No. 47. Under this responsive system against terrorism dependent on only the President's instruction, it is expected that there would be a poor response against terrors due to the lack of unified and integrated responsive agency as like the case of USA before 'the September 11th Terrorist Attacks'. And, where there is no legal countermeasure, it is impossible to expect the binding force on the outside of administrative agencies and the performances to prevent and hinder the terrorist actions can not but be limited. That is to say, the current responsive system can not counteract effectively against the new-terrorism and super-terrorism. Third, although there were some changes in Korean government's policies against terrorism. there still are problems. One of the most important problems is that the new responsive system against terrorism in Korea, different from that of USA, is not a permanent agency but a meeting body that is organized by a commission. This commission is controled by the Prime Minister and the substantial tasks are under the National Intelligence Service. Under this configuration, there can be the lack of strong leadership and control. Additionally, because there is no statute to response against terrorism, it is impossible to prevent and counteract effectively against terrorism. The above summarized suggests that, because the contemporary super-terrorism or new-terrorism makes numerous casualties of unspecified persons and enormous nationwide damages, the thorough prevention against terrorism is the most important challenge, and that the full range of legal and institutional arrangements for the ex post counteraction should be established. In order to do so, it is necessary for the government to make legal and institutional arrangements such as the permanent agency for protection from terrorism in which the related departments cooperates with together and the development of efficient anti-terror programs, and to show its willingness and ability that it can counteract upon any type of domestic and foreign terrorism so that obtain the active supports and confidence from citizens.
