A Study of Occupation Socialization Process of Security and Secretary Service
The occupational socialization process of security and secretary service goes through four stages of preparation, adaptation, conflicts, and maturity and dynamic and incessant changes. The preparation stage includes the preparation to become a security and secretary service, the importance of what to prepare, usefulness of college education, required courses, and certificates. The adaptation stage includes the percentage of bodyguard and secretary, systematic nature of work, stagnation of the job, abilities required for a security and secretary service, elements to work on, job satisfaction, information sources, professionalism of the job, and future of the job. In the conflicts stage includes conflicts at work, difficulty of security and secretary service, problem-solving efforts, advice and consultation, satisfaction with workload, job stress, perceptions of others for security and secretary service, experience of trying to get another job, and supplements. And the maturity stage includes the changes to the roles and capabilities of a security and secretary service, autonomy of business management, degree of others` recognition of one`s abilities, methods to evaluate job performance, salary, social status and pride, and efforts for self-development.
A Study on the Scope and the Role of PRIVATE GUARDS: Focusing on Guard Secretaries
The necessity of private guard became conspicuous as the interest in private security field has been increasing for safeguarding the personal safety of the protectee, because the professional executives and men of wealth cannot rely solely on the public authority or the police for their security. As the need for specialized security guards increases, this study will investigate the work range and the role of guard secretaries in depth in terms of security science through in-depth interview with guard secretaries who are currently working in the position, based on the role of the guard secretary from the previous researches on guard secretary. As a result of the study, generally the work scope of guard secretaries can be divided into three categories. In order of their importance, they were security which protects the body, life and property of the employer, schedule management which is managing the schedule of the employer, and confidentiality which is managing and protecting information. These results suggest that the role of guard is more important than secretarial role. It was revealed that the role of safety manager who is responsible for the safety of the protectee was the most important in the role of the guard secretaries. Secondly, the role as protocol manager for managing formal ceremony was considered to be important. Thirdly, the role as information manager for managing various information and date was considered to be important. In addition, the role of work manager, health care manager, business facilitator, and customer manager were considered to be important in the order of their importance. As with the results of work scope, security and safety were found to be the most important factors. The results of questionnaire showed that work capacity, physical ability, self development and interpersonal relationship were the most important ability of guard secretaries in order of their importance. These results should be the basic data that can provide guard secretaries' concrete work scope and role, and professionalism for better guard secretary services. In addition, since the research on the security secretary is insufficient, further research for the work scope and role of the guard secretary through careful interest and various research methods is needed.

Kinematic Modelling and Simulation of a 2R Robot Using SolidWorks and Verification by MATLAB / Simulink Regular Paper
The  simulation  of  robot  systems  is  becoming very popular, especially with  the  lowering of  the cost of computers,  and  it  can  be  used  for  layout  evaluation, feasibility studies, presentations with animation and off‐ line programming. The  trajectory  planning  of  redundant manipulators  is  a very  active  area  since  many  tasks  require  special characteristics  to  be  satisfied.  The  importance  of redundant manipulators has  increased over  the  last  two decades  because  of  the  possibility  of  avoiding singularities  as  well  as  obstacles  within  the  course  of motion.  The  angle  that  the  last  link  of  a  2  DOF manipulator makes with the x‐axis is required in order to find the solution for the inverse kinematics problem. This angle  could  be  optimized  with  respect  to  a  given specified  key  factor  (time,  velocity,  torques)  while  the end‐effector  performs  a  chosen  trajectory  (i.e., avoiding an obstacle) in the task space. Modeling  and  simulation  of  robots  could  be  achieved using  either  of  the  following  models:  the  geometrical model (positions, postures), the kinematic model and the dynamic model. To  do  so,  the  modelization  of  a  2‐R  robot  type  is implemented. Our main  tasks  are  comparing  two  robot postures with the same trajectory (path) and for the same length  of  time,  and  establishing  a  computing  code  to obtain the kinematic and dynamic parameters. SolidWorks  and MATLAB/Simulink  softwares  are  used to check the theory and the robot motion simulation. This  could  be  easily  generalized  to  a  3‐R  robot  and possibly therefore to any serial robot (Scara, Puma, etc.). The verification of the obtained results by both softwares allows  us  to  qualitatively  evaluate  and  underline  the validityof  the  chosen  model  and  obtain  the  right conclusions. The results of  the simulations are discussed and an agreement between the two softwares is certainly obtained.
