Recently, SNS has become an important channel for marketing as well as personal communication. However, cybercrime has also evolved with the development of information and communication technology, and illegal advertising is distributed to SNS in large quantity. As a result, personal information is lost and even monetary damages occur more frequently. In this study, we propose a method to analyze which sentences and documents, which have been sent to the SNS, are related to financial fraud. First of all, as a conceptual framework, we developed a matrix of conceptual characteristics of cybercriminality on SNS and emergency management. We also suggested emergency management process which consists of Pre-Cybercriminality (e.g. risk identification) and Post-Cybercriminality steps. Among those we focused on risk identification in this paper. The main process consists of data collection, preprocessing and analysis. First, we selected two words 'daechul(loan)' and 'sachae(private loan)' as seed words and collected data with this word from SNS such as twitter. The collected data are given to the two researchers to decide whether they are related to the cybercriminality, particularly financial fraud, or not. Then we selected some of them as keywords if the vocabularies are related to the nominals and symbols. With the selected keywords, we searched and collected data from web materials such as twitter, news, blog, and more than 820,000 articles collected. The collected articles were refined through preprocessing and made into learning data. The preprocessing process is divided into performing morphological analysis step, removing stop words step, and selecting valid part-of-speech step. In the morphological analysis step, a complex sentence is transformed into some morpheme units to enable mechanical analysis. In the removing stop words step, non-lexical elements such as numbers, punctuation marks, and double spaces are removed from the text. In the step of selecting valid part-of-speech, only two kinds of nouns and symbols are considered. Since nouns could refer to things, the intent of message is expressed better than the other part-of-speech. Moreover, the more illegal the text is, the more frequently symbols are used. The selected data is given 'legal' or 'illegal'. To make the selected data as learning data through the preprocessing process, it is necessary to classify whether each data is legitimate or not. The processed data is then converted into Corpus type and Document-Term Matrix. Finally, the two types of 'legal' and 'illegal' files were mixed and randomly divided into learning data set and test data set. In this study, we set the learning data as 70% and the test data as 30%. SVM was used as the discrimination algorithm. Since SVM requires gamma and cost values as the main parameters, we set gamma as 0.5 and cost as 10, based on the optimal value function. The cost is set higher than general cases. To show the feasibility of the idea proposed in this paper, we compared the proposed method with MLE (Maximum Likelihood Estimation), Term Frequency, and Collective Intelligence method. Overall accuracy and was used as the metric. As a result, the overall accuracy of the proposed method was 92.41% of illegal loan advertisement and 77.75% of illegal visit sales, which is apparently superior to that of the Term Frequency, MLE, etc. Hence, the result suggests that the proposed method is valid and usable practically. In this paper, we propose a framework for crisis management caused by abnormalities of unstructured data sources such as SNS. We hope this study will contribute to the academia by identifying what to consider when applying the SVM-like discrimination algorithm to text analysis. Moreover, the study will also contribute to the practitioners in the field of brand management and opinion mining.

In this article, I would like to analyze the conditions in applying the LCC method for each construction type by selecting 10 apartment complexes among the Turn-key projects which have been ongoing for the last 5 years. In addition, this article will identify the problems to the application of double landscape architecture and suggest improvement measures. Among the 10 case targets, a total of 151 LCC analyses were conducted, and the average application ratio placing for each construction type was shown in the following order: architecture (34.4%)> electricity (21.2%)>machine (18.5%)>civil engineering (13.2%)>landscape architecture (12.6%). As numbers show, landscape architecture was the lowest. The ratio of LCC reduction amount was shown in the following order: machine (32.1%)> architecture (23.9%)>electricity (23.4%)>civil engineering (17.5%)>landscape architecture (3.1%). The field of landscape architecture had a reduction amount that was about 5 to 6 times lower than civil engineering which had a similar number of LCC analysis cases. The total LCC analysis items of landscape architecture was 19, including 15 double packing material, 1 building covering, 1 grass planting, 1 planting infrastructure, and 1 facility. The following measures were suggested to promote LCC analysis in landscape architecture: first, set an analysis item that considers the construction expense ratio of landscape architecture; second, legal regulation of landscape architecture and expansion of its application; third, prepare VE/LCC standards which are suitable for landscape architecture.

Korea has 30 years of experiences in environmental impact assessment (EIA). Although EIA includes sanitation-public health factor, considering health impacts, among 74 unit projects of 17 sections, health impacts haven't been properly considered or have been ignored in many cases. The increasing awareness on the importance of health impacts has triggered this study to seek an optimal introduction scheme of health impact assessment (HIA). The processes of EIA already include screening, scoping, analysis, impact assessment, consultation, document review, decision making and monitoring, in which they would be the essential parts of HIA. In this context, integrating HIA into the existing EIA process could be the most effective way to use the benefits in both legal and procedural processes existed and to avoid the confusion and overlapping since the close relationships between environment and health impacts might be. Furthermore, it is desirable that the existing sanitation-public health factor should be substituted by and extended to environment-health factor with sufficient determinants to properly consider health impacts. When considering the first step of HIA, the prospective and qualitative approach is suitable more than the retrospective and quantitative one due to the lack of database accumulated. Similarly, an approach based on epidemiology and toxicology could analyze the limited evidences and impacts related to human disease, whereas one based on socio-science and psychology could provide the effective means available for predicting how the people and community will act by the change of surroundings. Checklist approach with various and comprehensive health determinants focused on prospective and qualitative methods will be very useful for more convenient and progressive dissemination of HIA. Various checklist approaches of toolkits could be found from HIA documents elsewhere, for example Westminster Toolkit, and they would be helpful to figure out how to develop common procedures and health determinants for checklist, in which the unique characteristics on korean cultural and political context compared to abroad should be carefully considered since checklist would be the most basic and essential part of HIA. After the establishment of checklist and procedural processes, the pilot projects should be conducted. Main purpose of pilot projects is to apparently prove the effectiveness and profitability of HIA. Pilot projects should be implemented to decide the effectiveness and suitability of HIA for future projects, programs and policies, and should be provided as the positive cases that can be achieved through the proper implementation and progress.

The Convention on the International Regulations for Preventing Collisions at Sea, 1972 (COLREGs) was adopted to prevent ships from colliding with other ships or any object such as the seabed. COLREGs have been codified and refined since the mid-19th century, and have reached the present. Therefore, the terms and sentences used in COLREGs also have distinct academic and legal connotations. However, in the Maritime Safety Act of the Republic of Korea, which translated COLREGs into domestic law, the "risk of collision" and the "danger of collision" was used in the law without distinguishing their meanings. Accordingly, the difference between "risk" and "danger" was analyzed with reference to the definition of risk by an authoritative international organization of the United Nations such as the International Maritime Organization and the International Organization for Standardization as a well-known and authoritative non governmental organization. In addition, the cases codified in COLREGs and translated cases in the Maritime Safety Act were analyzed to highlight the need for amending the Maritime Safety Act. From the perspective of safe navigation, it is expected that the Maritime Safety Act in the future would distinguish between "danger" and "risk" so that the efforts of watch officers to prevent collisions could be further systematized.

The concept of 'wilful misconduct" was initally used in article 25 of the Warsaw Convention of 1929. The concept was defined in the Hague Protocol, 1955, as having the following two differing concepts: i) "with the intent to cause damage" and ii) "recklessly and with the knowledge that damage would probably result." The concepts contained in the Hague Protocol were used in various international Conventions on carriage by sea, such as Article 2(e) and Article 3(4) of the Protocol adopted at Brussels on Feb. 23, 1968 to amend the International Convention for the Unification of Certain Rules of Law relating to Bills of Lading, signed at Brussels, Aug. 25, 1929(Hague-Visby Rules), Article 13 of the Athens Convention relating to the Carriage of Passengers and their Luggage by Sea, Dec. 13. 1974, Article 4 of the Convention on Limitation of Liability for Maritime Claims, 1976, Article 8(1) of the U.N. Convention on the Carriage of Goods by Sea, 1978(Hamburg Rules) and Article 21 (1) of the U.N. Convention on International Multimodal Transport of Goods, Geneva, 1980. The same concepts were also adopted in Article 746, 789-2(1), 789-3(2) of the Korean Maritime Commercial Law, revised in 1991. As of yet, the legal system of Korean Private Law recognizes only the concepts of "Vorsatz" and "grobe Nachlassigkeit", as is the case with German Private Law. The problem is that the concepts in the Convention do not coincide precisely with the concepts of "Vorsatz" and "grobe Nachlassigkeit". The author has conducted a comparative analysis of the treatment of the concepts of wilful misconduct and its varied interpretations, that is, "with the intent to cause damage" and "recklessly and with the knowledge that damage would probably result" in the Anglo-American law and in the continental European law in the following manner: 1. Background in which the concept of wilful misconduct was introduced in the Warsaw Convention. 2. The concept of "dol" in French private law. 3. The concepts of "Vorsatz" and "grobe Nachlassigkeit" in Korean private law. 4. Analysis of the concept of wilful misconduct in Anglo-American case law. 5. Analysis of the cases interpreting the concepts of "with intent to cause damage" and "recklessly and with knowledge that damage would probably result" in various jurisdictions. 6. The need to incorporate the concepts of "with the intent to cause damage" and "recklessly and with the knowledge that damage would probably result." 7. Faute inexcusable in French private law. Based upon the comparative analysis, the author points out the difference between the concepts of "wilful misconduct" or "with the intent to cause damage" and "Vorsatz", and between the concepts of "recklessly and with the knowledge that damage would probably result" and "grobe Nachlassigkeit" in the Convention and that of the Korean Private Law system. Additionally, the author emphasizes the importance of the unification in the interpretation of the provisions of the Conventions world wide.

On December 31, 2018, an incident occurred where a doctor was attacked and killed by a patient carrying a lethal weapon in the outpatients' clinic of the psychiatric department of a tertiary general hospital. The suspect was diagnosed with bipolar affective disorder (manic depressive disorder) and has been hospitalized and cared for in the psychiatric ward of this hospital. This incident illustrates the necessity of more active cures and therapeutic intervention for mental patients with intellectual developmental disorders who require treatment considering the fact that a radical outcome has been caused by such a patient. However, on the other hand, there is also a need for an approach and analysis from the perspective of crime prevention for all medical departments. The reason for this is that even a tertiary general hospital equipped with the largest human resources, medical devices, facilities, and so forth, is susceptible to violence. As for illegal actions perpetrated against health and medical service personnel in medical institutions, such as verbal abuse, assault, injury, etc. there have neither been understanding shown for the current extent of damage in detail, nor discussions of active institutional improvement related to the seriousness of the act. It can be said that violence in the field of medical treatment is a realm requiring serious discussion and appropriate remedial actions. This is because when such incidents take place, if a patient who is supposed to get treatment from the damaged health care provider is in an urgent situation or on the waiting list of serious cases, he or she could suffer serious damage caused by deprivation of treatment opportunity, or secondary damage might be caused to the patient and/or a guardian who can hardly have an opportunity to take action. Accordingly, in this review, we would like to help create the necessary conditions for both health and medical service personnel and patients/guardians, respectively, to provide and receive medical treatment in a more secure environment. Therefore, objective assessment of the institution and issues relating to this aforementioned incident and general cases of violence occurring in medical institutions, and by suggesting legal and institutional improvements and solutions.

In this study, based on accident cases of manned and unmanned tower cranes, the types and causes of accidents were analyzed and tower crane accident prevention measures were proposed accordingly. As a result, 'lack of communication' was commonly analyzed as the biggest cause of accidents. Therefore, in this study, we investigated domestic and international systems and laws regarding signalmen responsible for communication between tower crane operators and workers and proposed the following three improvement methods. First, the signalman system must be legally and institutionally reestablished. Second, national agencies and private organizations with expertise should create standardized training manuals and distribute them to signalman educators, and create checklists to manage educators. Third, in the case of a site using a tower crane, the employer must mandatorily deploy a signalman with professional qualifications. Lastly, the results of this study are expected to highlight the differences in accident types and causes of manned and unmanned tower cranes and the need for legal and institutional improvement in the signal system.

Marine accidents and legal violations result from mistakes and negligences of ship officers, deck officers and engine officers, during the ship navigation and lay days. Due to these accidents and violations, these officers are subjected to disciplinary actions for certification. The disciplinary action, namely certificate punishment is carried out by right rules, processes and equity. However, it is revealed that present situations are different from the principles. For the purpose of finding current states relating to certificate punishment, this study examines and analyses 737 punishment cases, accomplished in 'B' regional office of oceans & fisheries for 5 years from 2014 to 2018. The contents to be analyzed are reprimand agencies, certificate kinds, officers ranks at that time, disciplinary level, violated acts, annual reprimand state, punishment rule and it process, and disciplinary reduction levels. From such valuations various problems, such as disciplinary level deviations among laws, insufficient punishments rules, disciplinary certificate deviation, insufficient reprimand reduction rules, and lack function of crew administrative disciplinary council, are identified. Finally, methods to alleviate the problems identified will be proposed. This study, for the first time analyses the actual administrative disciplinary cases for ship officers'certificates and proposes improvement plans for its incorporation in Korea, This analysis will be useful in the examination of the study for the ship officers and making a plan for them.

This paper proposes an action plan for local governments to safely utilize artificial intelligence technology in various local government policies. The proposed method analyzes cases of application of artificial intelligence-related laws and policies in Gyeonggi Province, Seoul City, and New York City, and then presents matters that local governments should consider when utilizing AI technology in their policies. This paper applies the AILocalism-Korea analysis methodology, which is a modified version of the AILocalsm analysis methodology[1] presented by TheGovLab at New York University. AILocalism-Korea is an analysis methodology created to analyze the current activities of each local government in the fields of legal system, public procurement, mutual cooperation, and citizen participation, and to suggest practical alternatives in each area. In this paper, we use this analysis methodology to present 9 action plans that local governments should take based on safe and reliable use of artificial intelligence. By utilizing various AI technologies through the proposed plan in local government policies, it will be possible to realize reliable public services.

With the increasing complexity and irregularity of disaster types, the need for cultural asset preservation and management from a proactive perspective has increased as a number of cultural properties have been destroyed and damaged by various natural and humanistic factors. In consideration of these circumstances, the Cultural Heritage Administration enacted an Act in December 2005 to enforce the regular commission of surveys for the systematic preservation and management of cultural assets, and through a recent revision of this Act, the investigation cycle has been reduced from five to three years, and the object of regular inspections has been expanded to cover registered cultural properties. According to the ordinance, a periodic survey of city- or province-designated heritage is to be carried out mainly by metropolitan and provincial governments. The Seoul Metropolitan Government prepared a legal basis for commissioning regular surveys under the Seoul Special City Cultural Properties Protection Ordinance 2008 and, in recognition of the importance of preventive management due to the large number of cultural assets located in the city center and the high demand for visits, conducted regular surveys of the entire city-designated cultural assets from 2016 to 2018. Upon the first survey being completed, it was considered necessary to review the policy effectiveness of the system and to conduct a comprehensive review of the results of the regular surveys that had been carried out to enhance the management of cultural assets. Therefore, the present study examined the comprehensive management status of the cultural assets designated by the Seoul Metropolitan Government for three years (2016-2018), assessing the performance and identifying limitations. Additionally, ways to improve it were sought, and a DB establishment plan for the establishment of an integrated management system under the auspices of the Seoul Metropolitan Government was proposed. Specifically, survey forms were administered under the Guidelines for the Operation of Periodic Surveys of National Designated Cultural Assets; however, the types of survey forms were reclassified and further subdivided in consideration of the characteristics of the designated cultural assets, and manuals were developed for consistent and specific information technologies in respect of the scope and manner of the survey. Based on this analysis, it was confirmed that 401 cases (77.0%) out of 521 cases were generally well preserved; however, 102 cases (19.6%) were found to require special measures such as attention, precision diagnosis, and repair. Meanwhile, there were 18 cases (3.4%) of unsurveyed cultural assets. These were inaccessible to the investigation at this time due to reasons such as unknown location or closure to the public. Regarding the specific types of cultural assets, among a total of 171 cultural real estate properties, 63 cases (36.8%) of structural damage were caused by the failure and elimination of members, and 73 cases (42.7%) of surface area damage were the result of biological damage. Almost all plants and geological earth and scenic spots were well preserved. In the case of movable cultural assets, 25 cases (7.1%) among 350 cases were found to have changed location, and structural damage and surface area damage was found according to specific material properties, excluding ceramics. In particular, papers, textiles, and leather goods, with material properties that are vulnerable to damage, were found to have greater damage than those of other materials because they were owned and managed by individuals and temples. Thus, it has been confirmed that more proactive management is needed. Accordingly, an action plan for the comprehensive preservation and management status check shall be developed according to management status and urgency, and the project promotion plan and the focus management target should be selected and managed first. In particular, concerning movable cultural assets, there have been some cases in which new locations have gone unreported after changes in ownership (management); therefore, a new system is required to strengthen the obligation to report changes in ownership (management) or location. Based on the current status diagnosis and improvement measures, it is expected that the foundation of a proactive and efficient cultural asset management system can be realized through the establishment of an effective mid- to long-term database of the integrated management system pursued by the Seoul Metropolitan Government.
