  • Robot calibration needs accurate measurements of robot end-effector position at a number of different robot configurations. One of the efficient ways of the measurement is "Touching on Jig" method suggested in [7], which utilizes a touch sensor and a fixture consisting of various sizes of blocks. By moving the end-effector to touch the surface of a block whose position relative to the other is known, the end-effector position relative to the fixture coordinate system can be obtained at the instant of touching. However, the global size of fixture is too small to cover the various configurations of the robot. Because of the manufacturing difficulties, the fixture cannot be manufactured large enough for well distributed position measurement. It results in the improvement of robot accuracy only in the limited space near to the fixture rather than over the whole space of the robot working volume. The paper proposes a method to resolve the above problem by measuring the end-effector positions with respect to several different coordinate system using the same measurement devices. It is found that the proposed method leads the improvements of robot position accuracy over the large space of working volume. The experimental studies are performed to show the validity of the method and their results are discussed.

  • For efficient operation, vital hand controls must be easily controlled by the operator from his normal working position. The primary working area based on operator's working comfort was developed to serve as a design guideline tothe control panel layout. Ten male subjects participated in the experiment in which working comfort was measured for two controls of a lever type control and a knob type control with respect to the frontal and sagittal distances from the body center and the slope of a workplace. The response surface methodolgy using a central composite design was employed to develop a prediction model for perceived working comfort of each control. Both controls have a similar pattern of comfortable working area, but the lever type control has slightly broader working area. The concept of the proposed working area is a significant extension to the conventional working area such as Farley's or Squires' curves. It is shown that the distance toa control device and the slope have a quadratic effect to working comfort. It is noticeable that comfortable working area exists outside the conventional working area. The result of the response surface analysis also indicated that a little slope of about 15 .deg. for a control panel improves working comfort.

  • This paper proposes a method for evaluating the work of manufacturing workers using MediaPipe as a risk factor for musculoskeletal diseases. Recently, musculoskeletal disorders (MSDs) caused by repeated working attitudes in industrial sites have emerged as one of the biggest problems in the industrial health field while increasing public interest. The Korea Occupational Safety and Health Agency presents tools such as NIOSH Lifting Equations (NIOSH), OWAS (Ovako Working-posture Analysis System), Rapid Upper Limb Assessment (RULA), and Rapid Entertainment Assessment (REBA) as ways to quantitatively calculate the risk of musculoskeletal diseases that can occur due to workers' repeated working attitudes. To compensate for these shortcomings, the system proposed in this study obtains the position of the joint by estimating the posture of the worker using the posture estimation learning model of MediaPipe. The position of the joint is calculated using inverse kinetics to obtain an angle and substitute it into the REBA equation to calculate the load level of the working posture. The calculated result was compared to the expert's image-based REBA evaluation result, and if there was a result with a large error, feedback was conducted with the expert again.

  • Much experience and knowledge is needed in welding because there are many working parameters and quantitative description is difficult. Therefore, introduction of expert system based on such data base has been required. In this study, welding heat and shape of bead was controlled by fuzzy inference with the welding condition, position error and voltage and current error of robot. For this, torch trajectory of robot was generated by modeling the working data with CAD and then welding was carried out through down loading to robot. And working error was controlled by on-line communication.

  • The purpose of this research study is to analyze the influence on the necessity of establishment of eco-friendly hospital by evaluating hospital employees' awareness and their satisfaction level of working environment. Questionnaire investigation was conducted in April 2014 throughout five different medium-size hospitals in Seoul, Gyeonggi and Chungcheongbuk provinces. 213 sets of survey were used to conduct Frequency Analysis, T-test, Dispersion Analysis(ANOVA) and Structural Equation Modeling Analysis. The research concluded that employees with higher level of education, working position and longer term of working experience were more aware about Eco-friendly hospital. In addition, male, doctor, and employees with higher level of education and working position were more satisfied with their working environment. And male, employees with higher level of education and working position were more aware about necessity of establishment of eco-friendly hospital. According to the Structural Equation Modeling Analysis, the awareness of Eco-friendly hospital and the satisfaction level of working environment were the varying factors that influence the necessity of establishment of Eco-friendly hospital. Therefore, it is crucial for hospitals that are preparing for establishing Eco-friendly hospital to raise employees' level of understanding of Eco-friendly hospital and their working environment satisfaction level.

  • Objective : The purpose of this study is to discuss the role and ways to improve the position and rights of Korean Medicine Doctors (KMDs) working at long-term care hospitals (LTCHs) through survey analysis. Method : (1) The legal and institutional position of KMDs is studied using current law and related papers. (2) The online survey was conducted through KMD community websites, targeted at KMDs working at LTCHs. Results : (1) Whereas there is perceived added benefit for the eight specializations for a specialist of Western medicine at LTCHs, in the case of a specialist of Korean Medicine, their value is not institutionally recognized at all. (2) A Western inpatient's medical fee is more than a Korean inpatient's medical fee, and the individual fee for the same medical treatment is also higher in Western hospitalization. So, Korean medical hospitalization actually cannot be made. Because of that, Korean Medicine Doctors find it difficult to be primary care physicians. (3) Musculoskeletal diseases and the aftereffects of cerebrovascular diseases were the most common chief complaints addressed in Korean medical consultations. Conclusion : This study shows that KMDs working at LTCHs have suffered many kinds of inequality. That is because of the limited medical scope of the current medical system and real constraints from the gap in Korean-Western medical fees by the National Health Insurance Corporation. Therefore, it is necessary to eliminate these variations along with revising the statute with continuous research.
