This paper aims to draw practical measures for the Protection of the Rights of the private security guards. The results of the analysis, and presents the legal definition if need be introduced for the protection of private security guards right, are as follows. First, it must be established in Private Security Act the basic provisions that assure the economic status of the private security guards. Secondly, there is a need to clearly define the scope of authority of private security guards. Third, there is a need to clarify the scope of physical force or power in the regulations relating to the duty of the private security guards. This provision during the "displayed its power", there is a possibility that is too arbitrary interpretation, it must be deleted. Fourth, it must be established by weighting penalties for assault of a private security guards. Finally, Private Security Act and the Petition Police Act has a difference in personality and the purpose of the enactment. So it is not desirable to be directly applied to private security guards the provisions that apply to the petition police.

This study conducted a survey to gauge the buying and wearing propensities of wearers of leg guards made for baseball catchers, as well as product characteristics of preferred leg guards. Data from the survey were analyzed to obtain basic data for the development of an advanced leg guard design. Degree of compression, horizontal distance, cross section view and outline 3D sketch were also analyzed from the 3D data of leg guards; in addition, mobility and kinematic analysis were conducted through a wearing test. The survey indicated that imported products dominate the current retail market because they are appreciated by customers in terms of fit, price, brand, and protection. Representative complaints of products were discomfort, pressure, and the heavy-weight of the leg guards in general attributed to overall structure and 3D shape. When the pressure was lower on the front area of knee, it feels better to wear and the average knee angular velocity during the up and down motion increased, which suggests a better design from a kinematic point of view. The knee is the primary part of the body responsible for any movement of the lower limbs; consequently, the degree of compression and support stability of the leg guards near the knee area are important factors to evaluate the performance of leg guards. The results of our study indicate significant opportunities for improvement in product design and the development of baseball leg guards along with an ergonomic design that considers the mobility of the knee, skin deformations is necessary to improve performance. The process followed in this study will be applicable to studies on other personal protective equipment for sports.

Objective: The objective of this study was to evaluate a work of guards, using an ergonomic method(work analysis and posture analysis). Background: Most studies about guards were conducted in the field of medical, problems of shift, and the physical problems of old workers and social problems. But, guards consist of vulnerability group so it needs an ergonomic research in musculoskeletal disorders. Method: A head of an ergonomic estimation was work analysis(determination of combined task, work tool, work time and frequency of combined task) and posture analysis(upper body and lower body) of workers based on the video. Results: The result showed that combined task of guards was classification of patrolling, security, cleaning and waiting. The security indicated the highest ratio in the work time of combined tasks. The results of posture analysis for guards indicated high value in neutral. But, lower arm indicated high value in bending(left: 59%, right: 50%). Conclusion: The results of ergonomic methods indicated that guards' physical work load was not high during work, but comfortable work environment would be required for old guards. Application: If an ergonomic rule can be integrated into existing work environments, the risk of occupational injuries and stress will be reduced.

Lately, with the increase of the private security industry, individual quality improvement of the private security guards is rising. Especially, in accordance with competence of the private security guards, in the base of individual technical or knowledge, the confidence of own ability is essential for the improvement of the private security industry. In accordance with the private security guards, the study of their competence is rare. But through the study of teenagers or members of the public organization, we can know the influence of variables competence. The purpose of this study is to show how the self-esteem, need for Achievement, relation with co-worker and supervisor, and leadership effect on competence. Consequently this study will offer effective ways to develop the private security guards competence. We can show that self-esteem effects competence of the private security guards between the need for achievement and self-esteem which are adjusted as the individual characteristic. Namely, the higher the self-esteem of the private security guards is, the higher competence is. The study shows that the relation with co-worker and supervisor of the private security guards doesn't effect competence. Unlike the previous studies, this study proves that contingent reward has a positive effect on the Private Security Guards competence in the transactional leadership. That is, the higher the contingent reward of leader is, the higher the level of competence of the Private Security Guards is.

Objectives : This study was to investigate the use of mouth-guards and maxillofacial injuries and to examined the relationship among variables in athletes group. Methods : The subjects were 459(86.5%), who were 18 years or older with mean age of 20.7 years. Data was collected using a self administrated questionnaire from May 25 to June 15, 2009. We surveyed maxillofacial injuries(temporo-mandibular disorders contained) and mouth-guards usage and confidence concerning mouth-guards in athletes. The data were analysed with chi-square analysis, fisher's exact test and logistic regression using the SPSS 15.0 windows. Results : Prevalence of body or maxillofacial injuries experiences was 54.5% for athletes and 47.1% for non-athletes groups(p>0.05). The other hand, the incidence temporo-mandibular disorders was 67.0% for athletes and 49.8% for non-athletes groups(p<0.05). The experience of the use of mouth-guards was 83.3% for athletes and 78.8% for non-athletes, there were not significant differences between athletes and non-athletes groups (p>0.05). Risk factors found to be significantly related to the occurrence of maxillofacial injury were: unused mouth-guards(OR=2.83), no rules for use of mouth-guards(OR=2.46). Conclusions : Based on the findings, maxillofacial injuries experience is highly associated with mouth-guards usage, not only athletes also general people should be educated on the use of mouth-guard in order to reduce the incidence of maxillofacial injuries.

This paper suggests the minimum number of vertex guards algorithm. Given n rooms, the exact number of minimum vertex guards is proposed. However, only approximation algorithms are presented about the maximum number of vertex guards for polygon and orthogonal polygon without or with holes. Fisk suggests the maximum number of vertex guards for polygon with n vertices as follows. Firstly, you can triangulate with n-2 triangles. Secondly, 3-chromatic vertex coloring of every triangulation of a polygon. Thirdly, place guards at the vertices which have the minority color. This paper presents the minimum number of vertex guards using dominating set. Firstly, you can obtain the visibility graph which is connected all edges if two vertices can be visible each other. Secondly, you can obtain dominating set from visibility graph or visibility matrix. This algorithm applies various art galley problems. As a results, the proposed algorithm is simple and can be obtain the minimum number of vertex guards.
