This study examines the relationship between intrinsic motivation and individuals' performance in the Republic of Korea armed forces and explores whether job stress mediates the relationship between intrinsic motivation and individuals' performance. The research questions are: (1) Does intrinsic motivation influence individual performance in military organizations? (2) Does job stress impact individual performance? and (3) Does job stress mediate the relationship between intrinsic motivation and individual performance? The study utilizes data collected from a 350 soldiers survey in the Special Forces Brigade and Special Assault Commando Regiment of the Republic of Korea's Army. We use structural equation modeling (SEM) to explore the mediation role among intrinsic motivation, job stress, and individuals' performance. Research findings suggest that intrinsic motivation negatively impacts job stress. We also find that job stress has a positive effect on firearm skills. Moreover, the study reveals that the relationship between intrinsic motivation and firearm skills is partially mediated by job stress.

Purpose: The purpose of this study was to identify the relationship between intrinsic motivation and learning outcomes of nursing college students who took the Fundamentals of nursing as a problem-based learning method. Methods: In this cross-sectional study, we identified the intrinsic motivations of 114 nursing students who completed problem-based learning using the Intrinsic Motivation Inventory. The t-test was conducted to identify differences according to intrinsic motivation, and correlation analysis was performed to confirm the relationship between intrinsic motivation and learning outcomes. Results: The group with higher intrinsic motivation showed higher scores in all domains of self-assessed learning outcomes than the lower group. It was the 'Relatedness with an instructor' that showed the highest correlation with the learning outcomes in the domains of intrinsic motivation. Conclusion: Problem-based learning is an effective learning method for cultivating the competencies needed for nurses. The intrinsic motivation of students is an important factor in the performance of problem-based learning. For the efficiency of problem-based learning, efforts should be made to develop and apply autonomy-supportive interventions that can enhance intrinsic motivation.

We analyze the buckling of a thin elastic plate due to intrinsic stresses in thin films attached to the surfaces of the plate. In the case of cylindrical buckling, it is shown that for a plate with clamped edges compressive intrinsic film stresses can cause flexural buckling of the plate, while tensile intrinsic film stresses cannot. For a plate with free edges, film intrinsic stresses, compressive or tensile, cannot cause buckling.

In this quantitative research, it was enhanced to understand the impact of intrinsic motivation on creative process engagement by examining the significant role of psychological safety on intrinsic motivation. These relationships were examined by targeting the employees working full-time for five star deluxe hotels. Total number of 230 responses had been collected out of 250 cases requested and he number of 213 cases was used for the final analysis. The data were analyzed using structural equation modeling with SPSS 19.0 and AMOS 7 software program. The results suggested that psychological safety is significantly associated with intrinsic motivation. Furthermore, the hotel employees' problem identification, information searching & coding, and idea generation are affected by intrinsic motivation. That is, intrinsic motivation plays a significant role for each sub-factors of creative process engagement in the hotel industry. The theoretical and practical implications of these findings are established and related suggestion for formulating marketing strategy is well discussed.

The relaxation of the intrinsic stresses in the diamond films fabricated by the hot filament CVD was studied, and it was confirmed that the tensile intrinsic stresses in the films could be controlled without any degradation in the quality of the diamond films. The tensile intrinsic stresses in the films decreased from 2.97 to 1.42 GPa when the substrate thickness increased from 1 to 10mm. This result showed that the residual stress was affected by the substrate thickness as well as by the interaction between grains. Applying of ＋50 V between the W filament and the Si substrate during deposition, the tensile intrinsic stress in the film deposited at 0 V was decreased from 2.40 GPa to 0.71 GPa. Such large decrease in the tensile intrinsic stress was due to $\beta$-SiC which acted as a buffer layer for the stress relaxation. However, the application of the large voltage above ＋200V resulted in the change of quality of the diamond film, and nearly had no effect on relaxation in the tensile intrinsic stress.

Metallic impurities, such as Fe, Cu, and Au, become generation and recombination centers for minority carriers when combined with oxide precipitates or silicon self-interstitial clusters. As these centers may cause leakage and discharge in silicon devices, their prevention through gettering of the metallic impurities is an important issue. In this article, key aspects of intrinsic gettering, such as oxygen control, wafer cleaning, device area denudation, and bulk oxygen precipitation are discussed, and a practical method of implementing intrinsic gettering is outlined.

In this paper, we consider a decision-theoretic oriented, objective Bayesian inference for the ratio of two normal variances. Specifically we derive the Bayesian reference criterion as well as the intrinsic estimator and the credible region which correspond to the intrinsic discrepancy loss and the reference prior. We illustrate our results using real data analysis and simulation study.

The study intended to investigate the relationship between transformational leadership and creativity of cooks with transformational leadership as antecedent variable. Transformational leadership has been assessed positively in variable studies as a leadership to improve employee's creativity. The authors also tried to explore structural relationships among transformational leadership, intrinsic motivation, and creativity by identifying the meditating role of intrinsic motivation in the relationship between transformational leadership and creativity of cooks. The study subject was CJ FOODVILLE, which is a representative company with its size, sales, and recognition as a domestic restaurant business. A survey was conducted with employees who were working as a cook in restaurants operated by CJ FOODVILLE in metropolitan areas. The results of the study showed that charisma and intellectual stimulation of transformational leadership positively influenced intrinsic motivation, but inspirational motivation and individualized consideration did not significantly influence intrinsic motivation. In addition, the four elements of transformational leadership did not significantly affect creativity. The findings of the study show that intrinsic motivation played a role as a mediation among charisma, intellectual stimulation, and creativity of transformational leadership. Therefore, the findings of the study suggested intrinsic motivation as an important factor affecting creativity of cooks.

Object : The purpose of this study was to investigate aging-related changes of intrinsic and extrinsic hand muscles in their strength, cross-sectional area and volume, force control, and multi-digit synergies. It was hypothesized that aging would negatively affect distal muscles (intrinsic muscles) more than proximal muscles (extrinsic muscles). Method : Nine young and eleven older right-handed participants underwent MRI scans of the hand and forearm. Muscle cross-sectional areas and volumes of the intrinsic and extrinsic hand muscles were determined. Result : Muscle volume of the intrinsic muscles were larger in the younger group than the older group while muscle volume of the extrinsic muscles did not differ. For the cross-sectional area, both the intrinsic and extrinsic muscles of the younger group were larger than the older group. The maximum strength of the intrinsic muscles of the young group was 31% greater than the older group ($399.1{\pm}26.4$ vs $270.2{\pm}22.9Ncm$, p < 0.05) while the extrinsic muscles showed no significant difference. Although the elderly group showed a trend of decreased force control and multi-digit synergies, no statistical differences were found. These findings indicate aging-related decreases in hand muscle size and strength affect intrinsic muscles more than extrinsic muscles, thus supporting the hypothesis that sarcopenia affects the muscle size and strength of distal muscles more than proximal muscles. Conclusion : The aging-related decreases in hand muscle size and function were more apparent in intrinsic hand muscles, located more distally, than extrinsic muscles, located more proximally.

본 연구에서는 중학교 2학년의 수학 학업성취도에 대한 교사와 부모의 성취압력과 수학 내재적 동기의 영향력과 조절효과를 검증하였다. 연구 결과, 수학 내재적 동기의 수준에 따라, 수학 내재적 동기가 높은 집단에서 교사의 성취압력은 수학 학업성취도에 부적인 영향을 미치는 반면, 수학 내재적 동기 중 하집단에서는 교사의 성취압력이 수학 학업성취도에 정적인 영향을 미치는 것으로 나타났다. 부모의 성취압력은 수학 내재적 동기가 높은 집단과 낮은 집단 모두 수학 학업성취도에 정적인 영향을 미치고, 특히 수학 내재적 동기가 중 상인집단이 하집단에 비해 수학 학업성취도에 더 큰 효과를 나타냈다. 이러한 연구 결과를 바탕으로 교사와 부모의 성취압력을 통해 수학 학업성취도를 높일 수 있는 방안이 논의되었으며, 후속 연구를 위한 연구의 제한점을 제시하였다.
