Social unrest from retaliatory crimes is increasingly becoming problematic. Recently, there was an accident involving a suspect who went to a hospital and committed acts of retaliatory violence 11 times. This person's reasoning was that he was imprisoned due to the hospital's reporting to the police. He was consequently arrested in Boeun Choongbook on December 27th 2014. Accidents like this one take place frequently around our surroundings. There are regulations and systems in place. Nevertheless, similar cases that continue to take place makes us wonder if criminal judicial systems work well. Lukewarm responses to retaliatory crimes is not only threatening social security, but also placing fears in the minds of ordinary citizens. If retaliatory crimes take place, most citizens become apprehensive about criminal judicial activities of the police and mistrust for criminal judicial system. This at times discourages people from reporting incidents and could eventually increase crime rate and cause various social problems. Even though there are legal and systemic control measures, retaliatory crime is an increasing trend. This study is going to examine tendencies of internal retaliatory crimes and discuss legal-systemical responses.

Purpose: This study intended to investigate how health and safety organization, management, activities and safety culture of healthcare industries are different from other industries (food, lodging, gas, and electricity industries). Method: Data were analyzed using '2005 The National Survey for Occupational Safety and Health Tendency'. Results: For health and safety training, both new training and regular training time of healthcare sector was lower than comparison sectors. For health and safety manager assigning form, there were many case in healthcare sector to assign a safety manager as a deputy and a health manager as an additional job, there were some differences from comparison sectors. It was found that establishment of countermeasures by cause investigation and analysis execution for occupational accidents in the healthcare sector was lower than comparison sectors. For health and safety activities and safety culture awareness, they were estimated in healthcare sector to be lower than comparison sectors. Conclusion: Healthcare sector had relatively lower health and safety activities and safety culture awareness compared with comparison sectors. So, it is required business owner's concerns and efforts to assign exclusively responsible health and safety manager and to activate health and safety training and occupational accident prevention.

The enterprise are facing potential SHE(safety, health and environment) accident to cause casualties or a financial loss and increasing social responsibility. So, SHE management system has to be voluntarily accomplished rather than passively with regard to SHE regulation. In this study, KW_SHE(Kwangwoon Safety, Health and Environment) management model is developed which materialize self-regulation SHE management system of individual workplace by the research and analysis of many domestic enterprise. This KW-SHE management model is intend to assess work-product vs. management expenses investment and critically evaluated for studying its benefits and limitations

In Gwangyang port, huge reclaiming work and developing harbor facilities are underway to built industrial complexes. So it is estimated that towing barges will increase and make overtaking, head-on, crossing situations with a lot of cargo vessels in narrow passages. And it is possible to cause severe marine accidents inside of the harbor. This paper has a purpose to produce some policies making navigational safety of towing-barge on Gwangyang Hysco temporary passage. So it is considered how the change of marine traffic capacity and the risk factors in passage navigation influence to towing-barge navigation. And also the questionnaire survey of pilots and VTS operator was conducted to find out what they think about the navigational safety of towing-barge incoming and outgoing in No.1 Yulchon industrial complexes.

Objective : In the retrospective analyzing 19 consecutive patients with subaxial cervical spine(C3~T1) injury treated by posterior cervical fixation and fusion, clinical manifestation, radiologic finding, operative technique, and postoperative results following 6 months were analyzed. Materials and Methods : Most common fracture level was C4-5, mean age 41, and male to female ratio 13 : 6. The most common cause of injury was motor vehicle accident(17 cases). In 19 cervical procedures, interspinous triple wiring was done in 14 cases, lateral mass plating in 5 cases, and additional anterior fusion in 2 cases. Results : Twelve weeks after operation, all cases were reviewed by plain cervical radiogram. In 17 cases that treated by posterior fusion only, 14 cases(81%) had kyphotic angle change less than $5^{\circ}$, 2 cases(12%) $5-20^{\circ}$, and 1 case(6%) more than $20^{\circ}$. Overall fusion rate was 88%, and there was no significant difference of bone fusion rate between autogenous bone graft and allogenous bone graft. Conclusion : In the case of severe posterior column injury or displacement, posterior approach seems superior to anterior approach, but in the case of combined anterior column injury, anterior approach is considered necessary. In this study, posterior fixation and fusion might be acceptable procedure for subaxial cervical fracture and dislocation, owing to its high fusion rate, low kyphotic angulation and low operation related complication rate.

The SMART Highway project combines road construction with advanced technology and vehicle telecommunications. Its expected outcome is a world-leading intelligent road that is green, fast, and comfortable. A vehicular ad-hoc network(VANET) is the core technology of the SMART Highway, whose transport operation is based on road vehicles. The VANET is a next-generation networking technology that enables wireless communication between vehicles or between vehicles and a road side unit(RSU). In the VANET system, a vehicle accident is likely to cause a serious disaster. Therefore, some information on safety is essential to serve as the key exchange protocol for communication between vehicles. However, the key exchange scheme of the general network proposed for a fast-moving communication environment is unsuitable for vehicles. In this paper, communication between multiple vehicles more efficient and secure key exchange at the vehicle certification by signcryption is proposed.

Principal Component Analysis (PCA) is useful statistical technique for finding patterns in data, and expressing the data in such a way as to highlight their similarities and differences. In this paper, 1417 marine casualties occurred in Korean littoral sea in recent 5 years, were examined by the PCA. The main results obtained were as follows : 1. Most of marine casualties resulted from the human factors such as careless operation and insufficient engine maintenance. 2. Collision and standing mainly resulted from steering room-related human factors such as careless guard, inadequate ship-handling, however engine damage and fire explosion mainly resulted from engine room-related human factor such as bad handling of engine system. 3. No. 1 principal component represents accident frequency, No. 2 principal component represents the cause and No. 3 principal component represents the pattern of marine casualties, respectively.

After heated discussion, National Police Agency decided not to install Red Arrow signal at such major intersections as Gwanghwamoon, Sejongro. The major issues can be summarized in the following reasons. The one is the conflict of color and symbol (red means STOP and arrow means PROGRESS), and it would confuse drivers and may cause traffic accident. The other includes high replacement cost. This paper delivered how much red arrow signal would affect (1) drivers start up delay time, (2) saturation flow rate and (3) vehicle headway. The result showed that there was no statistical difference in those even when a red arrow signal is placed.

It has been estimated that up to $80\%$ of all marine accidents have human elements as a cause. t of these, human elements of crew fatigue is main causes of marine accident. Crew fatigue involves sleep, schedule. workload. off-time. alcohol health and stress. With a ship handling simulator, the effect of alcohol on ship operational performance is studied for each 0.05 and $0.08g\%$ blood alcohol concentrations. A main effect for alcohol was found indicating that ship operational performance was significantly impaired by this alcohol relative to performance in the non-alcohol condition. The results of this research can be applied to minimize marine accidents as basic data.

Despite continuous safety management, the death rate of construction workers is not decreasing every year. Accordingly, various studies are in progress to prevent construction site accidents. In this paper, we developed an AI-based priority inspection target selection model that preferentially selects sites are expected to cause construction accidents among construction sites with construction costs of less than 5 billion won (KRW). In particular, Random Forest (90.48 % of accident prediction AUC-ROC) showed the best performance among applied AI algorithms (Classification analysis). The main factors causing construction accidents were construction costs, total number of construction days and the number of construction performance evaluations. In this study an ROI (return of investment) of about 917.7 % can be predicted over 8 years as a result of better efficiency of manual inspections human resource and a preemptive response to construction accidents.
