This paper analyzes the actual 'content' and 'role' of the intrinsic motivation of creative laborers during the creative production process. Based on semi-structured intensive interviews with 16 light-entertainment television PDs in South Korea, this paper articulated that intrinsic motivation towards creative work could be understood as a desire to maintain their level of enjoyment from creative work. The desire was classified into two different types of 'enjoyment', one was the enjoyment based on the expectation regarding the creative job, and the 'enjoyment' experienced primarily related to the creative production process that allows creative workers to actualize individual creative ambitions. In addition, such intrinsic motivation tended to provide a strong driving force for creative workers as they endured unfavorable working conditions that resulted from market principles(viewership ratings), economic stability, and work-life balance. This paper proposes that the tendency of creative workers to endure various undesirable working conditions is based on a strong intrinsic motivation to maintain their level of enjoyment from their creative career.

Canal-side roads frequently collapse due to an unexpectedly greater soft-clay thickness with a rapid drawdown situation. This causes annually increased repair and reconstruction costs. This paper aims to explore the effect of soft-clay thickness on the failure in the canal-side road in the case study of Phra Nakhon Si Ayutthaya rural road no. 1043 (AY. 1043). Before the actual construction, a field vane shear test was performed to determine the undrained shear strength and identify the thickness of the soft clay at the AY. 1043 area. After establishing the usability of AY. 1043, the resistivity survey method was used to evaluate the thickness of the soft clay layer at the failure zone. The screw driving sounding test was used to evaluate the undrained shear strength for the road structure with a medium-stiff clay layer at the failure zone for applying to the numerical model. This model was simulated to confirm the effect of soft-clay thickness on the failure of the canal-side road. The monitoring and testing results showed the tendency of rapid drawdown failure when the canal-side road was located on > 9 m thick of soft clay with a sensitivity > 4.5. The result indicates that the combination of resistivity survey and field vane shear test can be successfully used to inspect the soft-clay thickness and sensitivity before construction. The preliminary design for preventing failure or improving the stability of the canal-side road should be considered before construction under the critical thickness and sensitivity values of the soft clay.

Purpose: Most emerging-market countries are concerned about the technology boom, which is accompanied by an increase in revenue from online sales and services. This finding has been demonstrated during the COVID-19 pandemic; however, is this tendency continuing in the new normal, and what factors are driving the increase in consumer decisions? The purpose of this research is to investigate how the decision to utilize online services will be affected in the new normal as well as propose a new research approach in this field. Research Design, Methodology and Approach: By following a deductive research method associated with positivist philosophy, a survey in South Vietnam with 426 respondents using a convenience sampling method was conducted. The reliability of the measurement scales was examined by using the SPSS program. The SmartPLS programme was utilised to assess the measurement and structural models as well as test hypotheses by using partial least squares structural equation modelling. Results: According to the research findings, decision-making has been impacted by social influences, perceived usefulness, perceived ease of use, perceived trust, perceived price, and perceived convenience. Conclusions: The research results also bring significant contributions not only in practice in providing management implications but also in theory. The research model has also demonstrated the feasibility of employing the stimuli-organism-response framework and combining the theory of perceived risk with the technology acceptance model via the explanation of decision-making.

Using the magnet gear, it is possible to transmit power without mechanical contact. As the drive shaft in a magnet gear-based speed reducer system is isolated from the drive shaft, the system is a two-inertia resonance system that should cope with an external load with the limited air-gap stiffness. On the other hand, the drive shaft or low-speed side is controlled only by the torque of the drive shaft through an air-gap, and the excessive oscillation or the slip can then be generated because of an abrupt disturbance that is different from the general mechanical gear system. Therefore, the disturbance loaded at the low speed side should be measured or estimated, and considered in the control of the driving shaft. This paper proposes a novel full-state feedback controller with a reduced-order observer for the speed reducer system using a magnet gear with a unified harmonic modulator. The control method was verified by simulation and experiment. To estimate the load at the low speed side, a novel observer was designed, in which the new state variable is introduced and the new state equation is formulated. Using a full-state feedback controller including the observer, the test result against disturbance was compared with two D.O.F PI speed controllers. The pole slip was compensated within relatively a short time, and the simulation result about the estimated variable shows a similar tendency to the test result. The test results showed that the magnet gear-based reducer can be applied to an accurate servo system.

Current business environment asks the fundamental changes about business security. The essences of these changes are that the security management of today's global business is important task of managers and the security practitioner is professional who needs very specialized education and training with business thinking. Rapid process of globalization of global village tore down the business limit that was restricted on the geological areas' limitation. Rapid business environments' change that is driving depends on development of science and technology with globalization needs new paradigm to keep business continuity. With the process of globalization, Korea, which importance is gradually increasing in the national economy, has trade dependent economic system, which keeps power of national economy through trade, so Korean economic tendency is accelerating. To keep competitiveness in global market, new strategy that is different with existing domestic business management is necessary. That is, capacity of coping with outside risk in domestic business management is established in some degree, but business activities in foreign countries faces at numerous unexpected risks that differ from country to country such as difference with the custom, changes of corporate governance etc. To cope with these new risks effectively, new paradigm for business risk is necessary. Especially, flexibility of thinking like new paradigm is necessary to cope with new security risk effectively. To cope with security risk that occurs in the new business environment effectively and competes against international company in global market, company management and members' changes of cognition about security and innovative changes in security policy is necessary. In the basement of these changes, there is expansion of business security tasks, improvement of report line, enhancement of professionalism and status of security officers, variation of hands-on workers and increasing of investment to the security etc.

Psychophysical experiment was performed to investigate how audio-visual spatial disparity affects on perceptual space in peripheral vision. In the experiment, participants were exposed to two stimuli of vision and sound which comes simultaneously from different directions, respectively. The visual stimulus was implemented by 7 white LEDs which were located at an equal distance with 7 different angles of $-70^{\circ}$, $-40^{\circ}$, $-20^{\circ}$, $0^{\circ}$, $20^{\circ}$, $40^{\circ}$, and $70^{\circ}$ from the right front. Those audial stimuli were also implemented by loudspeakers which were placed at 9 different directions equally spaced by $5^{\circ}$ ranged from $-20^{\circ}$ to $20^{\circ}$. Each participant then evaluated spatial disparity between visual and audial stimuli with 5 levels of response, in which the higher level indicates the larger gap. When the visual stimulus is applied from the right, the results show that the response level gets higher for a larger angle between visual and auditory stimuli. A similar tendency for the visual stimulus with $0^{\circ}$ orientation was also be observed. On the other hand, when the visual stimulus is applied from the left, the response level gets lower for the larger angle.

The purpose of this study was to design the new teaching strategy based on the particulate model facilitating the reflective thinking (RE-PM) in the learning of the particulate nature of matter, and to investigate the effect of the new teaching strategy in compare with the traditional teaching strategy (TS-PM) after treating with new teaching strategy on preliminary teachers of elementary school. The problems of traditional teaching strategy are as follows: 1) Most of students didn't think the particulate model connected with practical material. 2) Most of students have a tendency of the rote memory on learning of the traditional particulate model. 3) The ratio of changing the view of continuous matter into the view of particulate nature of matter was very low, after learning the particulate model using of the traditional teaching strategy. The new teaching strategy facilitating the reflective thinking was more effective on the understanding of particulate nature of matter and the driving of motivation than the traditional teaching strategy in the learning of the particulate nature of matter.
