Objective: Stroking calves during the postnatal period could effectively improve human-calf relationships. The objective of this study is to examine how daily calf stroking frequency during the postnatal period affects the establishment of human-calf relationships. Methods: Six calves were stroked by a trainer for 6 minutes once daily for 5 days after birth (D1). Six calves were stroked by a trainer for 3 minutes twice daily for 5 days after birth (D2). A further four calves were stared at but not stroked as the control group. The overall stroking or staring duration was the same for all groups, at 6 min/d and 30 min over 5 days. The tests for reactions to the stationary trainer in an unfamiliar environment and avoidance distance measurements for an approaching trainer were conducted at 1 month and 3 months after the treatment. Results: Calves in both stroking groups approached significantly closer to the stationary trainer, vocalized less, and looked at the trainer shorter than the control group at 1 month. However, at 3 months, there was no significant difference between the D1 and the control group, whereas the D2 approached significantly closer to the trainer and vocalized less, and looked at the trainer for a shorter time than the control group. For the avoidance distance, the trainer could approach closer to both stroking groups than the control at 1 month, however, there was no difference among groups at 3 months. Conclusion: Our results suggested that the difference in the calf stroking procedure affected the established human-calf relationships, even though the total stroking duration was the same for all stroked calves. It is likely to be more effective to stroke more frequently than intensively when the aim is to establish better human-calf relationships within limited labor time.

Purpose - The purpose of this study was to substantiate the relationship between on-the-job training (OJT) characteristic factors and OJT outcomes and the moderating effect of the tie strength between a trainer and a trainee on the relationship. OJT characteristic factors were composed of a unit of work to be learned, trainee's motivation, trainer's ability, OJT design, and OJT support. OJT outcomes included job satisfaction and organizational commitment in the research. The tie strength means a sense of intimacy with a trainer. All of the OJT characteristic factors, OJT outcomes, and the tie strength were defined operationally as the perceived ones by a trainee. Research design, data, and methodology - This study analyzed the data of 302 employees in a domestic travel agency as early career for seven years or less. The main methods for the analysis were multiple linear regression analysis and moderating effect analysis. The whole process of the data analysis was conducted using the SPSS 21.0 for windows. Results - The results of the study are as follows: First, every five element of OJT, including unit of work to be learned, trainee's motivation, trainer's ability, OJT design, and OJT support, showed positive influence on OJT outcomes - job satisfaction and organizational commitment. Second, the tie strength between a trainer and a trainee was positively related with OJT outcomes. Finally, the strength of ties between the trainer and the trainee was found positively to moderate the relationship of a unit of work to be learned, OJT design, or OJT support, with OJT outcomes. However, the moderating effect of the tie strength was not significant statistically between the trainee's motivation or the trainer's ability, and OJT outcomes. Conclusion - In the study, it was demonstrated that every OJT characteristic factors have a positive contribution to job satisfaction and organizational commitment for early career employees. In addition, the study showed the need to pay attention to improve the quality of relationships between trainers and trainees, in order to increase the impact of a unit of work to be learned, OJT design, and OJT support. These findings suggest the implications in the three factors as external factors that constitute OJT. The three factors are made by HRD practitioners who are involved in design and operation of the program as well as their interventions to improve the quality of the relationship between trainers and trainees. On the other hand, it was demonstrated in the research that trainee's motivation and trainer's ability, regardless of their tie strength, have a direct impact on OJT outcomes by itself. Moreover, the trainee's motivation and trainer's ability are intrinsic characteristics, rather than external factors that constitute OJT. Therefore, they are unlikely to be changed by HRD practitioners' interventions. In conclusion, it was argued in the research that the trainee's motivation and trainer's ability should be a consideration in selecting and matching partners in OJT participants before starting OJT.

Today Human Personal Trainers are becoming very famous in this health conscious world. They teach user to achieve fitness goals in managed way. Due to their high fee and tight schedule they are unavailable to mass number of people. Another solution to this problem is to develop digital personal trainer portable instrument that may replace human personal trainers. We developed a portable digital exercise trainer device - BIOFIT that manages, monitors and records the user's physical status and workout during exercise session. It guides the user to exercise efficiently for specific fitness goal. It keeps the full exercise program i.e. exercises start date and time, duration, mode, control parameter, intensity in its memory which helps the user in managing his exercise. Exercise program can be downloaded from the internet. During exercise it continuously monitors the user's physiological parameters: heart rate, number of steps walked, and energy consumed. If these parameters do not range within prescribed target zone, the BIOFIT will alarm the user as a feedback to control exercise. The BIOFIT displays these parameters on graphic LCD. During exercise it continuously records the heart rate and number of steps walked every 10 seconds along with exercise date and time. This stored information can be used as treatment for the user by an exercise expert. Real-time ECG monitoring can be viewed wirelessly (RF Communication) on a remote PC.

The T-50/A-50 Golden Eagle was developed for a supersonic trainer and light combat aircraft. At the design stage, vibration control plans were established and applied. For cockpit vibration, crew comfort vibration level was defined by the requirement of MIL-A-8892. It is found that the T-50/A-50 meets the requirement of cockpit vibration from the flight test data analysis. This paper contains the results of cockpit vibration analysis using the flight test data and the results of human vibration analysis lot the pilot inside aircraft. The human vibration level of pilot is increased as dynamic pressure is increased and at the specific high dynamic pressure, the ride comfort indicates 'a little uncomfortable'. Overall analysis results show that the vibration level of T-50/A-50 cockpit is tolerable and not critical for pilot's comfort.

This study is concerned with a method which helps human to generate EMG signals accurately and consistently to make reliable design samples of function discriminator for prosthetic arm control. We intend to ensure a signal accuracy and consistency by training human as a signal generation source. For the purposes, we construct a human training system using a digital computer, which generates visual graphes to compare real target motion trajectory with the desired one, to observe EMG signals and their features. To evaluate the effect which affects a feature variance and a feature separability between motion classes by the human training system, we select 4 features such as integral absolute value, zero crossing counts, AR coefficients and LPC cepstrum coefficients. We perform a experiment four times during 2 months. The experimental results show that the hu- man training system is effective for accurate and consistent EMG signal generation and reduction of a feature variance, but is not correlated for a feature separability, The cepstrum coefficient is the most preferable among the used features for reduction of variance, class separability and robustness to a time varing property of EMG signals.

Human-robot cooperative tasks are increasingly required in our daily life with the development of robotics and artificial intelligence technology. Interactive reinforcement learning strategies suggest that robots learn task by receiving feedback from an experienced human trainer during a training process. However, most of the previous studies on Interactive reinforcement learning have required an extra feedback input device such as a mouse or keyboard in addition to robot itself, and the scenario where a robot can interactively learn a task with human have been also limited to virtual environment. To solve these limitations, this paper studies training strategies of robot that learn table balancing tasks interactively using deep reinforcement learning with human's facial expression feedback. In the proposed system, the robot learns a cooperative table balancing task using Deep Q-Network (DQN), which is a deep reinforcement learning technique, with human facial emotion expression feedback. As a result of the experiment, the proposed system achieved a high optimal policy convergence rate of up to 83.3% in training and successful assumption rate of up to 91.6% in testing, showing improved performance compared to the model without human facial expression feedback.
