The purpose of this study is to analyze combustion patterns by filling a specific container with a flammable liquid and performing combustion tests in a divided space. The container used for the test is made of plastic, 20 mm in depth and 150 mm in width. After the liquid was ignited, its combustion process was photographed using a digital camera and video camera. It was found that in the case of benzene, the flame reached its peak at the fastest speed about 60 s while in the case of alcohol, the flame reached its peak at the lowest speed about 360 s, which is approximately six times slower than the benzene. In most cases, when the flame reached its peak, smoke generated was dark as the plastic container and flammable liquid were combusted simultaneously. After completion of the combustion, it was possible to sample oil vapor from all flammable liquids excluding soybean oil as a result of the examination of oil vapor using a crime investigation tube. That is, it can be seen that there is significant difference in flame propagation speed, pattern, etc., depending on the combustible substances.

As to the increase of crime against children, the importance of safety in school area is more emphasized ever. Safety in school area can be achieved by the well-organized combination of physical, managemental and spatial planning factors. The purpose of this paper is to investigate the spatial planning direction to prevent crimes for the schools and their surroundings on the viewpoint of CPTED(crime prevention through environmental design). Field survey using checklist drawn up with 5 major CPTED principles was conducted for 7 schools(primary, middle and high schools) located at Noen New-town, Daejeon Korea. Problems derived from field survey were categorized to 5 CPTED principles and countermeasures were suggested together with computer graphic simulation. CPTED design principles and guidelines for spatial planning can make school area safer because these can assure natural surveillance, territoriality, natural access control, etc.

Recently, this government is implementing the "eradication of four social evils" policy to root out social evils which includes sexual violence, school violence, domestic violence and substandard food. In retrospect, these social evils are the crimes that have sprung from rapid social changes in Korea. These main four crimes not only badly affect certain victims but also spread their viciousness to broad population. Moreover, the prevention of the occurrence of the crime and the problem solving as an individual unit are hardly possible. Due to their critical effects and continuity, governmental safety policy enforcement is achieving higher support. As an alliance with the calling from the public for happier and safer life, this paper especially focus on regulating substandard food issue, according to the idea that food safety is an essential prerequisite for the healthy and happy life of the people. Through the reviewing, definition of the substandard food will be cleared and specified substandard food crimes will be introduced as well. And the paper will also pose questions in order to propose improved legal measures against the existing regulations, such as newly adding additional penalty article to food sanitation law.

As various crimes such as theft, assault, and sex crimes are increasing, each local government is installing CCTVs to prevent them, and operating and managing control centers for emergency response. When the control center detects a dangerous situation in the field, it responds immediately in connection with the police or 911. However, since it is managed by humans, the response speed is anomalous and the reality is that it is mainly used for post-processing. Therefore, through the artificial intelligence LED signage, it notifies the emergency situation at the site, and it serves as a warning function before getting help from passers-by or an accident occurs. In this paper, we design and research a warning system such as changing the lighting color of the LED signboard or making a sound by reflecting the artificial intelligence algorithm. We intend to contribute to public safety and social safety through this study.

The idea of this study was derived from awareness of local governments and police's limitation on attempts to 'creating safe park'. The purpose of this study is to examine current political measures of preventing various types of possible crimes in the park and the limitation of those policies. Furthermore, this study aims to suggest possible explanations to utilize Private Security Sector for the effective and continuous way of managing park safety by considering legal and practical solutions and its expectations. The methods of analysis used in this study are, first, literature review of current park safety management policies. Second, this article examined implications of strategies of those policies throughout the case study of the USA's park safety policy. Third, this study suggested plans of action and role of Private Security Sector to improve park safety. The results present several arguments for the park safety. First, legislation of mandatory crime preventing programme in the early stages of designing park is required. Introducing the 'park special judicial police system' to the major parks for a immediate response to the crime can be one of suggestions. Moreover, proactive police response systems, such as one of the Seoul Metropolitan Police's policies- 'returning safe parks to a citizen' are required. Second, the case study of the USA regarding park safety confirmed that major parks in the USA have rigorous and detailed park regulations. It also showed that those parks take not only preventing measures, but also follow-up measures against crimes. Third, the results suggest creating human resources by contracting out Park Managers and Private Security Sector that have specialized experiences and techniques to prevent crimes and public disorders. Overall in this study, increased citizen's satisfaction level, control of continuous and systematic crimes, the spread of joint-production of public safety, and increased fields of the Private Security Sector are expected from the findings.

Recently, as the era of economic cooperation on the Korean Peninsula approaches, the role of the building sector, such as humanitarian reorganization of North Korean housing, is increasing. The purpose of this study is to find out the current location of North Korean housing standards through the North Korean Housing Survey. For the survey, a survey was conducted through 79 North Korean defectors. The main construction methods of North Korean housing are reinforced concrete, steel framed, wooden framed, masonry, and reinforced concrete walled and prefabricated. The residential environment satisfaction items consist of durability, waterproof, heating, ventilation, heat insulation, air tightness, mining, soundproofing, disaster safety, fire safety, and crime prevention. The result is as follows. The housing construction method in North Korea, which lived at that time, consisted of 21 people (30.88%) of reinforced concrete frames, 18 people (26.47%) of wooden frames, 17 people (25%) of masonry walls, 5 people of prefabricated structures (7.35%), and reinforced concrete. Two people (2.94%) were walled. Among these, the wooden frame type had the lowest satisfaction level for each item, and the reinforced concrete had a high level of dissatisfaction in the items of heating, confidentiality, and disaster safety, and the other item had a high level of satisfaction. The masonry wall type has a relatively high satisfaction level in terms of insulation, confidentiality, mining, and disaster safety.

The nature of deaths occurred at sea may be revealed the differences from that in the land, but there is no comprehensive statistical analysis of deaths occurred at Korean Sea so far. Therefore, the cases of deaths or missing in the period 1993 - 2006 were analyzed by the cause, place of death, and results of preliminary investigation. In the period from 1993 to 2006, over 1000 peoples were died or missing every year. The cases of marine safety accidents including self-carelessness and mishap were approached over 60% and cases of homicide were less than 1%. The closure cases of preliminary investigation were reached over 70% and the most of deaths occurred in fishing vessels (the range of 20 ~ 99 tonnage). The suspension cases of preliminary investigation were reached to 70% of all missing and drowning cases. The results showed that the most of deaths occurred at sea could be prevented by the safety regulations including mandatory report of accidents, marine safety education and training, punishment the people responsible for the accidents. For the unidentified bodies, data should be collected and recorded for the future identification. The crime scene investigators should be trained to ensure the quality of their professional skills regularly.

As interest in drones controlled by remote technology rapidly increases worldwide, drones are used in many fields such as military, rescue, and transportation as future innovations in many countries. In particular, as the drone has been spotlighted as a new future strategic industry, it is also used for public purposes such as disaster relief and crime investigation. However, security concerns such as the penetration of major national facilities, collisions with aircraft, and the possibility of privacy infringement due to aerial photography are also being raised. Unlike the increased interest in drones, there have been few studies on drone use, drone safety, and public attitudes toward drone use. This paper analyzed the perceptions of drone attitudes, drone stability and policy support for drones for Korean and United Kingdom.

To develop the tourism industry, which is a 'no smoking environment-friendly green industry' and can contribute to creating jobs, it is the goal of top priority to resolve foreign tourists' discomfort and fear by allowing them to look around the country satisfactorily without fear and return to their home and inducing them to naturally promote tourism in South Korea to people around them. No matter how great tourist attractions a country has, there is not many foreign tourists who will go on a tour trembling with fear of crimes such as thefts, frauds, threats and blackmail. Therefore, it is necessary to prepare the conditions of tourism free from various illegal acts and inconveniences for domestic and foreign tourists, and for this, it is urgently necessary to make efforts to improve laws and institutions. Domestic tourists can report their complaints themselves through the Tourist Complaint Center of Korea Tourist Service, Inc. or Korea Consumer Agency, or to the police through the 112 Crime Report. In contrast, there are a lot of cases in which foreign tourists cannot receive compensation as it is not easy for them to report due to the differences in language, culture and the criminal justice system though they have suffered illegal acts or inconveniences. This, consequently, has an adverse effect that would disturb the tourism in South Korea as the tourists may spread its bad images to people around them after they return to their home countries with discomfort, so it is urgently necessary to establish a foreign tourist-centered tourist police system.
