Simulators were introduced in education as a tool to make advanced training standardized, less expensive, and without danger to those involved. In 1922 in the Unites States, Edward Link presented his homemade flight simulator, which became common place in both military and civilian aviation, known as the "Link Trainer". The development of mannequin simulators used for medical simulation education, training, and research is reviewed, tracing the motivations, evolution to commercial availability, and efforts toward assessment of efficacy of those for teaching cardiopulmonary resuscitation(CPR) for medical personnel and emergency medical technicians(EMT), cardiology skills, anaesthesia clinical skills, and crisis management. This study will provide a brief overview of simulators and trainers in several domains.

This study was conducted to investigate an attitude related to clinical laboratory science students' clinical practice. Data for this analysis was gathered from March to May, 2004 by the questionnaires of 348 students who are in their third year in 5 colleges and have experienced clinical practice. The students were satisfied with the term of clinical practice (70.4%) and the first factor influencing them in clinical practice was sincerity (45.1%), and the second was basic knowledge (19.8%). In the contents of clinical practice, 53.2% were satisfied but 43.3% of them showed negative responses because their practice was limited and they were simply assistants. 74.1% were satisfied after experiencing clinical practice and the first factor was improvement of understanding and interest in their major (65.9%) and the second was the gain of confidence (20.1%). Among anxieties in the clinical practice, a shortage of self-confidence (47.7%) was the highest. 81.3% of them wanted to maintain medical technologist's life continuously. It appeared that the more satisfied with their major, the more satisfied with the clinical practice (p<0.05). As a result, the students were satisfied with the clinical practice and fresh experience generally. But they were relatively unsatisfied with the practicality, and connection with the lecture. As a part of efforts to formulate an effective system for clinical practice, it is necessary to establish concrete goals and detail check lists to guide these students among professors, trainers and students.

As a measure of health, the percentage of body fat has been utilized for many ergonomist, physician, athletic trainers, and work physiologists. Underwater weighing procedure for measuring the percentage of body fat is popular and accurate. However, it is relatively expensive, difficult to perform and requires large space. Anthropometric techniques can be utilized to predict the percentage of body fat in the field setting because they are easy to implement and require little space. In this concern, the purpose of this study was to find a regression model to easily predict the percentage of body fat using the anthropometric circumference measurements as predictor variables. In this study, the data for 10 anthropometric circumference measurements for 252 men were analyzed. A full model with ten predictor variables was constructed based on subjective knowledge and literature. The linear regression modeling consists of variable selection and various assumptions regarding the anticipated model. All possible regression models and the assumptions are evaluated using various statistical methods. Based on the evaluation, a reduced model was selected with five predictor variables to predict the percentage of body fat. The model is : % Body Fat = 2.704-0.601 (Neck Circumference) + 0.974 (Abdominal Circumference) -0.332 (Hip Circumference) + 0.409 (Arm Circumference) - 1.618 (Wrist Circumference) + $\epsilon$. This model can be used to estimate the percentage of body fat using only a tape measure.

As one of the useful approaches to enhance safety managers' competencies, this study aims to suggest improvement plans in terms of education in school and on the job for safety managers. Educational needs at schools and job training institutes were surveyed with 321 safety managers in Daejon & Chongju Area. Correspondence with university professors at safety engineering departments via email was also conducted. Collected data were put into the R stochastic program in codified form and quantitatively analyzed through two-dimensional cross-tabulations and a chi-square test. With respect to school education, three academic subjects were examined. Job training was suggested to be conducted as 'training for trainers', which should be more flexible in terms of contents, method, and fees. Periodical investigation of educational needs for safety personnel who are consumers of safety education and training was also proposed.

Objective: The purpose of this study was to provide quantitative and objective data of throwing movement in baseball catcher through biomechanical analysis. Method: Eight high school baseball catchers (age: 17.3±0.7 yrs, height: 175.3±4.5 cm, weight: 82.5±9.0 kg, Career: 7.4±2.1 yrs) participated and 3-dimentional motion capture system and electromyography (EMG) were used in this study. Results: The maximum center of mass position displacement was observed in forward direction. The linear velocity magnitude of the upper extremity segments were showed as "wrist>elbow>shoulder" which is indicative of kinematic chain. For kinetic EMG data, we also observed the greater muscle activation in the left brachioradial and erector spine muscles muscle that during throwing movement. Conclusion: We expect that biomechanical data from this study will provide important training implications to baseball coaches and trainers in order to effectively train their baseball catchers.

The Dr. LEE Jong-wook-Seoul Project (DLSP) in the Lao People's Democratic Republic (PDR) is a long-term development cooperation initiative aimed at upgrading the medical education capacity at the University of Health Sciences (UHS) in the Lao PDR. Under the project, eight faculty members from UHS were trained at the Seoul National University College of Medicine for a 12-month period during 2010-2011. Using a training-of-trainers model, we estimated the effect of DLSP on the learning outcomes of students, which was measured using the standard test scores of the students. The questionnaire developed by the Medical Education Assessment Consortium in Korea was given to the students and both the percent-correct and standardized scores were examined. The evaluation strategy was to compare the learning outcomes of the students taught by the trainees with those that were not and to compare the medical topics taught by the trainees with other topics. It was found that the first group of trainees in the DLSP was associated with an increase of 1.5 in the percent-correct test scores for basic medicine. While the interpretation requires caution, it is consistent with the view that a training program for faculty members could be effective in improving the teaching capacity of medical schools in developing countries.

In order to provide a safe free-weight-training environment to people without workout trainers, we suggest a smart bench press machine with an automatic weight control system sensitive to user tiredness. Physical weight plates on the machine are replaced with a hydraulic cylinder as a press load and the cylinder knob is coupled with a step motor to change its tensile force automatically in-between lifting exercises. Three subjects participated to verify the usability of the smart bench press machine. They were asked to lift a 6-RM press load 10 times with 3 different lifting conditions: 1) no assistance, 2) a human assistance, and 3) the automatic weight control. All subjects were not able to complete the 10 sets without assistance due to tiredness, but they finished the full sets under the two assistive conditions. Average lifting speeds under the automatic weight control condition showed the most consistent level. Normalized quasi-tension data based on surface electromyogram signals of both Pectoralis Majors revealed that the subjects maintained the target muscle activation level above 50% but not more than 80% throughout the 10 sets. Therefore, the smart bench press machine is expected to both keep pace with the lifting exercise and reduce risk of injuries due to excessive muscle tensions.
