Despite the fact that navigation technology and educational programs were developed and maritime law has been enforced strictly, the number of maritime accidents has not dropped significantly. In order to reduce traffic accidents at sea, the preventive index for maritime accidents is designed and measured to evaluate and visualize the activities performed. The survey module is composed of preventive domains such as education, engineering, enforcement and information. The index was abstracted from the statistics of maritime accidents causes(2010~2012). It can be evaluated by using the newly developed survey modules. It was found that there is some correlation between the index value and the accident rate of maritime traffic. It is expected that this index will become another useful tool to help prevent maritime accidents.

In this study, factors influencing the parking policy compliance (i.e. levying a garage option on car buyers) were identified, and then, were applied to the theory of planned behavior. To find out the influence of factors and their path, the study built a parking policy compliance model using structural equation modeling. The independent variables such as attitude, subjective norm, perceived behavioral control had positive effects on the parameter describing the efforts to secure his garage, but the parameter impact on the dependent variable was not significant. In the end, the independent variables affected the dependent variable was not significant. The perceived behavioral control utilizing regulations had positive effects on the parking policy compliance behavior, but past behavior such as street parking and prowling to find a free parking space had a negative effect on parking policy compliance behavior.

Purpose: The purpose of this paper is to examine the recently rising number of foreign drug offenders in Korea and suggest improvement measures for the Korean drug policy. Method: This paper analyzed the preceding research, statistical data, etc., on related fields and referred to overseas cases to suggest improvement measures. Result: The foreign population living in Korea increased in 2000s, and the foreign drug offender cases are increasing accordingly. The survey on foreign drug offenses showed that the case of foreign drug offender is higher than the case of Korean drug offenders by 1.2 to 3.3 times. In 2021, the foreign drug offender cases increased by 6.5 times compared to 2012. Especially, the number of psychoactive drug-related drug offenses increased dramatically. The drug smuggling also remarkably increased starting from 2016 as some people earned a lot of money from smuggling the drugs Conclusion: To cope with the foreign drug offenders effectively, this paper suggested intensive monitoring of the foreign drug offenders and weighting on the drug offenders depending on their home country to intensify the entry standards on foreigners who are likely to smuggle drugs.

It is noted that illegal hazardous foods containing unauthorized drugs or synthetic drung analogues are increasing. Especially, reported are unknown compounds that have the modified chemical structures of the anti-impotence drugs such as sildenafil, vardenafil, and tatalafil. In addition, it is very reserved, since illegal synthetic compounds having similar chemical structures modified from anti-impotence drug to avoid the government inspection are not proved their safety at all. This review in ulation to food safety, lists the illegal compounds added to foods and describes about the analytical methods to chanacterize 16 anti-impotence drug analogues such as homosildenafil, hongdenafil, pseudovardenafil, aminotadalafil, hydroxyhomosildenafil, hydroxyhongdenafil, dimethylsildenafil, xanthoanthrafil, hydroxyvardenafil, norneosildenafil, demethylhongdenafil, piperidinohongdenafil, carbodenafil, thiosildenafil, dimethylthiosildenafil, and acetylvardenafil.

Purpose: The recent increased use of Personal Mobility (PM) has been accompanied by a rise in the annual number of accidents. Accordingly, the safety requirements for PM use are being strengthened, but the laws/systems, infrastructure, and management systems remain insufficient for fostering a safe environment. Therefore, this study comprehensively searches the main problems and improvement methods through a review of previous studies that are related to PM. Then the priorities according to the importance of the improvement methods are presented through the Delphi survey. Method: The research method is mainly composed of a literature study and an expert survey (Delphi survey). Prior research and improvement cases (local governments, government departments, companies, etc.) are reviewed to derive problems and improvements, and a problem/improvement classification table is created based on keywords. Based on the classification contents, an expert survey is conducted to derive a priority improvement plan. Result: The PM-related problems were in 'non-compliance with traffic laws, lack of knowledge, inexperienced operation, and lack of safety awareness' in relation to human factors, and 'device characteristics, road-drivable space, road facilities, parking facilities' in relation to physical factors. 'Management/supervision, product management, user management, education/training' as administrative factors and legal factors are divided into 'absence/sufficiency of law, confusion/duplication, reduced effectiveness'. Improvement tasks related to this include 'PM education/public relations, parking/return, road improvement, PM registration/management, insurance, safety standards, traffic standards, PM device safety, PM supplementary facilities, enforcement/management, dedicated organization, service providers, management system, and related laws/institutional improvement', and 42 detailed tasks are derived for these 14 core tasks. The results for the importance evaluation of detailed tasks show that the tasks with a high overall average for the evaluation items of cost, time, effect, urgency, and feasibility were 'strengthening crackdown/instruction activities, education publicity/campaign, truancy PM management, and clarification of traffic rules'. Conclusion: The PM market is experiencing gradual growth based on shared services and a safe environment for PM use must be ensured along with industrial revitalization. In this respect, this study seeks out the major problems and improvement plans related to PM from a comprehensive point of view and prioritizes the necessary improvement measures. Therefore, it can serve as a basis of data for future policy establishment. In the future, in-depth data supplementation will be required for each key improvement area for practical policy application.

Most countries have been promoted the legislative policy for the legal employment, causing a social conflicts by illegal immigrants in any countries. Despite the efforts to alleviate the illegal aliens, there are not nearly enough successful cases, and encounter a social problem about illegal stay worker. China is no exception. At present, the issue of China's foreign illegal employment is expected to be a social problem in the present and the future. However, the legislative policy against immigration control law and illegal foreign employment in China is very neglectful. There is a lack of adjusting rule of law on illegal foreign workers in China, and the remedy is also insufficient. It is necessary to secure a legal right for the protection of the Rights of illegal foreign workers based on the international norms. For this purpose, the illegal foreign workers related law should be enacted, and based on this, administration should be strengthened. The trend of major countries of illegal aliens is centered around an employer hiring strictly regulated. There is a need to have a strengthen regulation on the employer rather than the foreign workers in China. To this end, employer who hire illegal foreign workers should be required to receive considerable disadvantages such as penalties and fines, prison sentences, as well as various kinds of burdens and repatriation costs. It is necessary to run the voluntary repatriation(Freiwillige $R\ddot{u}ckehr$) program of illegal immigrants, and there is a need to take action for illegal immigrants who voluntary return home within a certain period are exempt from penalty. In conclusion, China must push ahead with a direction of positive policy in related ministries rather than sit on its hands on the wrong choice or a confusion of an employer and foreign workers with a policy on illegal foreign residents in limbo.

Purpose: The purpose of this study is to examine the new drugs that recently have shown rapid increase and provide solutions to eradicate them. Method: This study used the relevant preceding studies, statistics, and overseas materials to identify the new drug problems and suggest solutions. Result: Compared to the past, the numbers of criminals detected for the administration, distribution, and production of drugs are rapidly increasing. According to the statistical data on drugs in 2021, the number of drug-related cases decreased compared to the previous year. However, there are concerns because the amount of detected drugs increased more than three times, and the age group of drugrelated criminals are getting younger. Such results are largely affected by the spread of new drugs. In particular, it is deemed to be affected by the spread of new drugs, such as fentanyl, yaba, khat, kratom, etc., as well as the new psychoactive drugs and hemp-related materials. Conclusion: In response to spread of new drugs, this study suggests simplifying the temporary classification of drugs, enforcing control of foreign drug users, strengthening the cooperation with relevant institutions, such as Korea Customs Service and the Ministry of Food and Drug Safety, and intensifying the punishment on the drug users in order to strengthen the countermeasure against the new drugs.
