As a countermeasure under accidental occurrence situation, First, as application form of martial arts, A security guard foster ability that can protect a target person of guard and own body under accidental occurrence situation through incessant martial arts practice. To achieve this purpose, incessant training mental power and physical strength reinforcement should be kept on to prevent, therefore make a safety control function for such as weapon, small arms, explosive, vehicles terror etc. happened under accidental occurrence situation. Second, according to the contents of training based on the classification category of martial arts for security guard under accidental situation, a security guard must keep safety distance necessarily lest a target person of gurad should be attacked by attacker, therefore, intercept an attack opportunity if a safety distance between a target person of guard and attacker is not kept. Third, It is to practice confrontation techniques based on the type of attack. A security guard must develp situation disposal ability that can cope properly with the attack using empty hands, murderous weapon, small arms, explosive by case or individual or mass of threat that impose danger and injury in a target person's body of guard.

Purpose of this research about reduction the scholastic systematic triangular position of the security guard martial art which repeats a development is insufficient with demand of the while society to recognize and for the philosophic value research of security guard martial art composition principle puts out with the one method and from the reporter to search the aesthetics which appears does. In order to attain the goal of the research which sees the literature which relates with an security guard martial art widly, was an investigation and observed the aesthetics from concept and martial art of aesthetics and this the technical free use ability from actual site of the technical find which leads the practice voluntary repetition practice of security guard martial art with character and the body guard aesthetic integral part experience possibly did, there being will be able to acquire an aesthetic inspiration, confirmed. So the security guard martial art follows the composition principle of maximization central attitude and shock point breath control and mental intensive etc. of reinforcement of direction shock of relativity redundancy mental moral culture body agreement characteristic force and relaxation force and is completed and will be able to embody an aesthetic value with aesthetic elements of technical polishing process inside goes about reduction.

To develop baseball catcher leg guards, 3-dimensional (3D) methodologies, which are 3D human body data, reverse engineering, modeling, and printing, optimized guard design for representative positions. Optimization was based on analysis of 3D body surface data and subjective evaluation using 3D printing products. Reverse engineering was used for analysis and modeling based on data in three postures: standing, $90^{\circ}$ knee flexion, and $120^{\circ}$ knee flexion. During knee flexion, vertical skin length increased, with the thigh and knee larger in anterior area compared to the horizontal dimension. Moreover, $120^{\circ}$ knee flexion posture had a high radius of curvature in knee movement. Therefore, guard designs were based on increasing rates of skin deformation and numerical values of radius of curvature. Guards were designed with 3-part zoning at the thigh, knee, and shin. Guards 1 and 2 had thigh and knee boundaries allowing vertical skin length deformation because the shape of thigh and knee significantly affects to its performance. Guard 2 was designed with a narrower thigh and wider knee area than guard 1. The guards were manufactured as full-scale products on a 3D printer. Both guards fit better in sitting than standing position, and guard 2 received better evaluations than guard 1. Additional modifications were made and an optimized version (guard 3) was tested. Guard 3 showed the best fit. A design approach based on 3D data effectively determines best fitting leg guards, and 3D printing technology can customize guard design through immediate feedback from a customer.

Recently the demand for civil bodyguards and security guards shows rapid growth by the social development and improve the quality of life. However the supply and training system have some limitations in spite of the high demand guard-secretary. The main role of secretaries has been to accompany superiors in order to maintain their dignity or trait. But the secretaries are required to play additional roles of safety managers such as a security manager, a protocol manager, an intelligence manager and a protective driver in order to overcome the domestic and the international safety environment and to elevate the quality of service as a competitive work. So, the purpose of this article is to analyse current situation of civil body and security guard training industry and to seek an educational model. For it, the following questions will be examined. First, Do the professional training organizations meet social demand for the body and security guards? Second, What kind of training has to be provide for the body and security guards? and what the qualifications of the trainers? Then, what are the differences in training courses between private organizations and universities? Is there differences in the job placement among the trainers of private organizations and universities? etc.. In summary to meet the social demand common curriculum for the body and security guard will be drawn from the analyses of diverse training organizations with different training courses in contents, training periods, educational value, and social aim.

PURPOSE: This study find out the effect of torque and power through various solidity of mouth guard on shoulder flexion and extension. METHODS: This study was conducted with healthy adults in their 20s Korean. Cybex system was used to measure the torque and power fo shoulder joint flexion/extension during isokinetic contraction when the various solidity mouth guard was used and no mouth guard was used. RESULT: The results of this study were summarized as follows: relative torque and average power was showed significantly difference between non applying mouth guard and applying hard type mouth guard during shoulder flexion and extension at isokinetic contraction. CONCLUSION: The application of hard type mouth guard was increased torque and power in joint of body. which may be clinically useful.

본 연구의 목적은 그간 사회의 요구로 인하여 발전을 거듭하고 있는 경호 경비학의 전공과목으로서 무도의 역사와 함께하는 경호무도의 학문적 체계 정립이 부족함을 인식하고 경호무도의 철학적 가치 연구를 위하여 그 한 방법으로 경호무도 구성원리 내에서 발견될 수 있는 미학적 가치를 탐색해보고자 하였다. 본 연구의 목적을 달성하기 위해 경호무도관련 학위논문 및 무도와 미학 관련 문헌을 광범위하게 조사였으며 이를 바탕으로 미학의 개념과 무도에서의 미학을 살피고 이를 토대로 경호무도 수련자의 반복 수련을 통한 기술습득과 경호원의 실제현장에서의 기술구사능력이 미학적 구성요소에 대한 체험을 가능하게 하고 심미적 감흥을 획득할 수 있음을 확인하였다. 궁극적으로 경호무도는 상대성 반복성 정신수양 신체일치성 힘의 방향 충격의 강화 및 완화 힘의 극대화 중심자세와 타격점 호흡조절 및 정신집중 등 그 구성원리를 따라 완성되어가는 기술연마 과정 속의 심미적 요소들로 인하여 미학적 가치를 구현할 수 있다고 여겨진다.
