This study aims to explore the role of Khan's engagement dimension previous study in mediating the relationship between work-life balance and in-role and extra-role performance of salesforce. To measure the data, a quantitative approach conducted through a survey of the sales force in the financial services industry sector in Makassar City, Indonesia. We determine the sample by using purposive sampling technique, and a total of 188 salesforce respondents. SEM-PLS with the second-order model was applied to test the measurement model and the mediator role of the engagement. The results show that the engagement dimension fully mediates the effect of work-life balance on both in-role and extra-role performance direct or indirect effect. the findings in this study also address the great concern of both individuals and organizations that the antecedents of the work-life balance variable are fundamental reasons for improving performance. The results of this study indicate that the work-life balance program positively influences engagement. Overall, we can conclude that commitment not only serves as a means for employees to fulfill formal job requirements. This can also encourage them to take action that goes beyond the precise requirements of their work by presenting them physically, emotionally, and cognitively in the work environment.

This paper introduces experimental design and components model for analysing the impact of parameter(in the field of kinematics and sensor) on performance of hard-kill torpedo defence system. The simulation is implemented at the level of engagement and its scope is limited to final stage of engagement where main function of anti-torpedo system is operating. It improves the fidelity of physical realism by precise model of simulation components in the perspectives of kinematics, sensor capability and acoustic detection theory. This paper provides the experimentation methodology for evaluating parameter sensitivity which is required to analyze in advance of development the defense system with novel concepts. In addition, the experimental result shows the tendency of defense capability according to parameter adjustments.

This paper proposes an improved test and evaluation methodology to be conducted for a in-flight threat-countermeasure encounter scenario. Although the conventional test method adopted in the precedent researches allows high precision and safety, such full-scale method is practically not appropriate to apply to small-scale test rounds for evaluating the subparts of the ammunition. To address this problem, this study suggests a readily-applicable, small-scale test and evaluation method of the subpart of the ammunition in firing test. In the threat-countermeasure encounter scenario, the results of several tests demonstrate that the proposed technique does not deteriorate the precision when the engagement point should be adjusted.

Assessment of implant mobility is an important and reliable method to clinically evaluate implant stability. PerioTest is a precise and reproducible device that cam dynamically measure the reaction of damping characteristics of peri-implant tissue. The aim of this study is to evaluate the effects of amount of implant surface area, diameter, type, implantation site, degrees of cortical engagement, and length of time in function on PTVs and to find out the most determining factor on PTVs. The results are as follows 1. 5.0mm diameter implants show significantly lower PTV than that of 3.75mm diameter implants. 2. PTV in the mandible is significantly lower than that of the maxilla 3. In the maxilla, there is no significant difference in PTV during the first year of implant function, but during the second year a significant decrease in PTV is noted. 4. In the mandible, there is a significant decrease in PTV during the first and second year of implant function. 5. Implantation site seems to be the most determining factor on PTV among the influencing factors in this study. In conclusion, the amount of implant surface area, type, degrees of cortical engagement had no significant effect on PTV, but installation site and diameter influenced significantly on PTV

A recent air defense missile system is required to have a capability to intercept short-range super-high speed targets such as tactical ballistic missile(TBMs) by performing engagement control efficiently. Since flight time and distance of TBM are very short, the missile defense system should be ready to engage a TBM as soon as it takes an indication of the TBM launch. As a result, it has to predict TBM trajectory accurately with cueing information received from an early warning system, and designate search direction and volume for own radar to detect/track TBM as fast as it can, and also generate necessary engagement information. In addition, it is needed to engage TBM accurately via transmitting tracked TBM position and velocity data to the corresponding intercept missiles. In this paper, we proposed a method to estimate TBM trajectory based on the Kepler's law for the missile system to detect and track TBM using the cueing information received before the TBM arrives the apogee of the ballistic trajectory, and analyzed the bias of prediction error in terms of the transmission period of cueing data between the missile system and the early warning system.

This thesis investigates the meaning of a performer's energy taking into an account of the full bodily engagement as the flow of energy and/or psychophysical readiness focusing specifically on the significance of qualitative bodily transformation. In this contemporary era, the dominance of performer training and its approaches to acting/training has very frequently meant that how to play a character in a textual based approach by emphasizing on interpreting and impersonating the role as real as possible. In this sense, as a performer trainer, from my observation and research findings shows that it is common for the term energy is not to be motivated by what a performer's body needs within a specific moment in specific performance which they are working on. To address the problematic issues, this thesis begins by interrogating the practical meaning of transformation with addressing the principle and process of movement by means of the flow of energy on stage. For a performer, inhabiting/integrating his/her body and mind as oneness and/or unity means s/he sincerely encounter, confront, and therefore listen to his/her body in here and now. Because since the performer's physical appearance completely defined his/her psychological state, no one can play either the past or the future in the moment. In this manner, an appropriate use of energy synonymous with the flow of energy correspondence with the given time and space in which the performer's body informs and initiates movement as necessary action. To be precise, the performer's bodily movement either visible or invisible in a sense of training and rehearsal is perceived as attaining or achieving psychophysical involvement as the full body engagement which enable to make the event happen in the right moment. Here, this thesis argues that the significance of a performer's inner intensity reminds us of the necessity of qualitative transformation on which the performer could discover his/her own mode of awareness as well as a way his/her body function in the given circumstance. From this point of view, this research finding would advocates that the performer's body maintains in the field of energy flow where his/her conscious effort and/or mindfulness disappear. The performer's movement is a manifestation of the whole bodily engagement by means of being as real in that moment rather than representing reality.

This thesis examines the term a performer's sincerity taking into consideration issues of the bodily engagement and specifically addressing the place of a performer's respiration. The main emphasis in this research will be on the tendency to a performer's anticipation in contrast to a state of being in the moment on stage. Exploring and reconsidering the process of training the performer's body reminds us the significance of rigorous training in an appropriate way(s) within which the performer's body enables to meet the principles of acting with the nature of theatre as his/her body is responding and subordinating to the moment on stage. Here, this thesis argues that we need to acknowledge that initiating any bodily movement has to understood and then inhabited by negating a performer's active willingness where the source of energy, breathing roots, then transfers through the entire body rather than the mere use of the external forms or muscles. To be precise, maintaining the internal energy through the moment informs how the performer interrogates where and what s/he is in a state of whole body engagement preventing the performer's self-doubt about what s/he is doing in the next moment(s). The process should be considered as a qualitative bodily shift gazing into his/her inner territory to reach behind a linguistic and/or an intellectual sense. The research finding suggests that a performer's art is to allow the animating respiration in order to facilitate and enliven his/her entire body as oneness which in turn moves his/her scene partner(s) as well as the spectator in the here and now.

Exercises using a Balance Board (BB) are effective in developing balance, strengthening core muscles, and improving physical fitness and concentration. In particular, the Smart Balance Board (SBB), which integrates with various digital content, provides appropriate feedback compared to traditional balance boards, maximizing the effectiveness of the exercise. However, most systems only offer visual and auditory feedback, failing to evaluate the impact on user engagement, interest, and the accuracy of exercise postures. This study proposes an Immersive Smart Balance Board (I-SBB) that utilizes multiple sensors to enable training with various feedback mechanisms and precise postures. The proposed system, based on Arduino, consists of a gyro sensor for measuring the board's posture, a communication module for wired/wireless communication, an infrared sensor to guide the user's foot placement, and a vibration motor for tactile feedback. The board's posture measurements are smoothly corrected using a Kalman Filter, and the multi-sensor data is processed in real-time using FreeRTOS. The proposed I-SBB is shown to be effective in enhancing user concentration and engagement, as well as generating interest, by integrating with diverse content.

Background: Human cytomegalovirus UL18, a MHC class I homologue, has been considered a natural killer (NK) cell decoy. It ligates LIR-1/ILT2 (CD85j), an NK inhibitory receptor, to prevent lysis of infected target cells. However, precise role of UL18 to NK cell cytotoxicity is yet elusive. Difficulty in clarifying the function of UL18 lies in complication in detecting UL18 mainly due to low level expression of UL18 on the surface and gradual loss of its expression. Methods: To overcome this hurdle, cDNA of cytoplasmic tail-less UL18 was constructed and expressed in swine endothelial cell (SEC). The expression level and its stability in the cell surface were monitored with FACS analysis. Results: Surface expression of UL18 is up-regulated by removing cytoplasmic tail portion from UL18F (a full sequence of UL18). SECs transfected with a cDNA of UL18CY (a cytoplasmic tail-less UL18) stably expressed UL18 molecule on the surface without gradual loss of its expression during 6 week continuous cultures. In the NK cytotoxicity assay, UL18 functions either inhibiting or activating NK cell cytotoxicity according to the source of NK cells. We found that there is individual susceptibility in determining whether the engagement of NK cell and UL18 results in overall inhibiting or activating NK cell cytotoxicity. Conclusion: In this study, we found that cytoplasmic tail is closely related to the regulatory function for controlling surface expression of UL18. Furthermore, by constructing stable cell line in which UL18 expression is up-regulated and stable, we provided a useful tool to clarify exact functions of UL18 on various immune cells having ILT2 receptor.

The purpose of this study was to evaluate the stress patterns within fractured mandibles generated by reduction forceps and to determine the optimal position of the reduction forcep. Twenty-seven mandibular models were fabricated using a photoelastic resin. Each of the three sets of mandible models prepared was osteotomized according to one of three different fracture types(symphysis, parasymphysis and body fractures). After reducing the cut segments, a reduction forcep was placed into different engagement holes to compress the segments. Photoelastic stress analysis was used to visualize the stress patterns within the fractured mandiblular models generated by the reduction forcep. In the case of symphysis or parasymphysis fractures, an optimum distribution of stress over the fracture site was achieved when placing the reduction forcep more than 12.5mm on either side of the fracture line between the midway level bisecting the mandible and 5mm below the level. In the case of body fractures, optimum stress distribution was achieved when the reduction forcep was placed more than 15mm from the fracture line on the midway level. In conclusion, a correct use of reduction forceps helps to provide a precise threedimensional reduction for mandibular fractures.
