Purpose: This study aimed to explore the rationality for and countermeasures against the use of prehospital patient restraint (PPR) techniques in efforts to limit violent behavior toward 119 emergency medical technicians (EMTs). Methods: Previous countermeasures to limit violent behavior toward 119 EMTs and medical personnel were focused on strict reactive and passive proactive responses. However, those in support of the countermeasures do not believe that violent and criminal behavior can be limited or extinguished by strengthening the punishment unconditionally. Results: When it comes to the far-reaching effects of stigmatization on people who engage in violent and criminal behavior, it is possible that unconditional punishment leads to more crime, increases the costs of imprisonment, and consequently, adds to the financial burden of the government. Conclusion: Thus, we are faced with an urgent need to prepare legal grounds for the use of PPR techniques by 119 EMTs for agitated or combative patients only, with direct medical oversight. Moreover, the legal foundation for the use of PPR techniques also needs to be established for emergency medical personnel. The use of PPR techniques not only ensures the safety of emergency medical services personnel, but also protects patients from injuring themselves and others.

University residence halls have become one of the most important issues for students when selecting their academic institutions. However, in South Korea, while universities maintain technologically up-to-date facilities, when it comes to safety or security, the management is unsatisfactory. As a result, the number of violent crime has been increasing. However, there are few researches in terms of practical validity of CPTED Guidelines even though a myriad of researchers study about CPTED Guidelines. Therefore, this study endeavours to investigate the validity of theoretical CPTED Guidelines that to what extent it might be adopted for design process. As a methodology, Space Syntax Convex map and Visibility Graph Analysis (VGA) are chosen. As a result, since the types of space which have a high level of Space Syntax Index are analogous with space treated on CPTED Guidelines, it roughly shows that the theoretical CPTED Guidelines could be adopted in practical architectural design process. Furthermore, it reveals that there is a close relationship between detail design guide stated in CPTED Guidelines and the result of VGA. That is, through the analysis, it is proved that the validity of CPTED Guidelines is quite enough to be adopted in practical design process.

This paper is concerned with an Internet of Things (IoT)-based unmanned home-delivery box system, in which the system is developed with a prototype using a weight sensor, shock sensor, the Arduino and Raspberry-Pi of open-source hardware platforms. The developed system provides several functions such as a safe storage means, prevention of delivery-theft, and remote control of the home-delivery box, etc. Specifically, the system recognizes the arrival of goods by detecting the weight of deliveries and sends the arrived message of deliveries to the recipient' smartphone, and also controls (i.e., open and close) the locker of the unmanned home-delivery box system remotely with the smartphone. Furthermore, the developed system provides automatically a warning alarm around the unmanned home-delivery box when an external shock is applied to the home-delivery box, and sends a message on the shock to the recipient' smartphone. The major functions of the developed home-delivery box system have been verified in a realistic environment, and confirmed to work well. With the application of the developed home-delivery box system to the homes and offices where recipients are always not to stay, it is expected to significantly improve the safety of delivered goods as well as to effectively prevent the delivery operatives posing as a crime.

With the recent diversification and complication of buildings, the functions of building are also developing. As much as the development of buildings, the machine or equipment used for them is also developing. Thus, all sorts of domestic/foreign industrial facilities and fire stations in the whole nation are using the electric shutter that could meet the insulation just like the exterior wall of general buildings, for bringing-in/storage and crime prevention/fire prevention. Currently, various types of electric shutters are used. Such wrong operation and poor management are causing many panel-falling accidents. This study researched the reduction of electric shutter panel-falling risk by reviewing the domestic/foreign laws and standards, and researching the new safety equipment. First, the causes for falling and accident types were drawn by analyzing the cases of electric shutter accidents. After that, a checklist as the measures for reducing the falling of electric shutter in building was suggested by analyzing the items for the inspection of electric shutter.

The purpose of this study is to investigate residential characters and consciousness about housing environment concerned with earth housing, and to suggest basic data reflectible on the planning of earth housing. Residential characters and consciousness are investigated with the people lived in forty seven earth housings located in nationwide scale through interviews and questionnaire. As a result, it is shown that a reason of health like sick house syndrome, residential environments such as ventilation and lighting, site environment such as neighbor and greenfield are very influential elements to the consciousness of inhabitants. Meanwhile, approximation of residential area, the connection with public facilities including medical service, educational and commercial conditions, additionally, preparation of disaster and crime prevention in a viewpoint of safety are pointed out as relatively weak ones. It means that earth housing is not systematically fixed as a residential site because it is personally progressed by small number of peoples having different reasons. For the improvement of systematic housing environment, development and proposition of various model are needed on earth housing and its site.

This paper proposed an accident prediction model in order to prevent accidents in mountain areas using a big data analysis. Data of accidents in mountain areas are shown as graphs. We have analyzed cases: the number of accidents per year, day of week, time of day to find patterns of the negligent accident in mountain areas. The proposed prediction model consists of weighted variables of the accident in mountain through visualized big data analysis. The model of danger index performance is demonstrated by showing accident-prone areas with weighted variables.

This paper presents a landscape design for the meeting plaza around the "Myeonmok" subway station. The site is located at 120-1 Myeonmok 1-dong, Jnngrang-gu, Seoul, and its area is approximately $2,664.7m^2$. The goal of the design was to make an environmentally friendly meeting and rest place which was related to the subway station. To achieve this goal, concepts of history, tradition, sense of place, community, environmental friendliness, and function were developed. For history, stone sculpture and art tiles symbolizing the paleolithic area were introduced because the site is located near an archaeological site of paleolithic min. For tradition, considering that the site is a 'sailing ship' form in terms of Pungsu theory, a sculpture symbolizing a sailing ship and paving patterns symbolizing waves were introduced. For asense of place, a grass hill, a waterfall and a pond symbolizing an old meadow for horse pasture was introduced. In addition, a multi-purpose round plaza as a meeting place for local community and subway users was proposed. A zelkova grove symbolizing a village forest was proposed for a restand relaxation area. All areas were designed to be environmentally friendly and barrier-free. Concepts for a defensible space wereadapted for safety because the site was a crime-prone area.

It is no doubt that information technology is the key factor of national safety. Information technology is positively useful for national security such as crime prevention and detection, criminal investigation, disaster management, and national defense. However, it might be a threat to the security as we saw in the examples such as '3.4 DDoS attacks' and 'Nong-hyup Computer Network Failure.' Although the effect that information technology makes upon the national security is immense, the current legal system does not reflect these changes well. National security should be kept during 'prevention-response-recovery' process regardless it is in the online on offline. In addition, public administration for national security should be based on laws. However, the current legal system is lack of legislative basis on cyber and physical disaster, and the laws on the response to disaster might cause confusing. Therefore, this study examines the limitation of the current legal system on national security, and suggests directions for the development of the system based on the new establishment of the legal concept for 'national security'.

The purpose of the study was to identify the level of housing choice behavior by using the factors of residential satisfaction level, mobility motivation, and housing needs of potential purchasers in Bukgu New Housing Area, Ulsan. The survey used questionnaire from 326 households living in Bukgu and nearby area and analyzed using descriptive statistics. The research results showed low degree of residential satisfaction in storage space and neighborhood. The mobility motivations were improvement of physical environment improvement, education environment, walking road, view and lighting. The housing needs for indoor spaces showed to want more functional arrangement than the room size. The housing needs for outdoor spaces showed to want neighborhood environment in connection with the education or hospital facilities, the welfare facilities for pre-kindergarten children and elders and the leisure facilities. And the housing needs for facilities were floor furnishing for health, crime prevention system for safety needs, housekeeping appliance against environmental pollution, additional function for energy saving. The housing needs for common spaces showed that the residents preferred playing facilities by age group, exercise facilities, the community hall and the rest room which can do games or meetings.
