PURPOSE: The purpose of this study is to provide the basic data for developing the self-leadership program by identifying the effect of self-leadership on intrinsic motivation among physical therapy students. METHODS: One hundred physical therapy students in E university of Gyeonggido were recruited by convenience sampling from October 4 to 14, 2016. Of them, 89% were chosen and 79% were analyzed after excluding the cases with wrong answers. The survey, using Likert's five scales was conducted with fifteen items of intrinsic motivation (Cronbach's ${\alpha}$, .84) and thirty-five items of self-leadership (Cronbach's ${\alpha}$, .90). Frequency analysis, correlation analysis regression diagnostics, and multiple regression analysis were done with SPSS 20.0 Statistics program (IBM, Korea). RESULTS: The total score of Self-leadership was 3.61 and of substrategies was 4.05 (Natural reward strategy), 3.38 (Behavior-focus strategy), and 3.43 (Constructive thought pattern strategy), respectively. The score of intrinsic motivation was 3.43. The substrategy of Self-leadership indicated positive correlation with intrinsic motivation. The correlation values in higher order were .75 (Natural reward strategy), .66 (Behavior-focus strategy), and .61 (Constructive thought pattern strategy). The Constructive thought pattern strategy (t=5.18, p=.00) and Natural reward strategy (t=2.10, p=.38), except Behavior-focus strategy were effective on intrinsic motivation, according to the multiple regression analysis. CONCLUSION: Before stepping up to the next level of being a physical therapist, students must go through the educational program to improve the Constructive thought pattern strategy and Natural reward strategy.

Self-leadership means a person's ability to make his thought or behavior in a right way by controlling it himself. Strategies of the same leadership can be largely categorized into three, behavior focused, natural reward and constructive thought strategies. In this study, the foresaid styles of self-leadership strategy are discussed from the perspective of dental lab laboratories' business environment of Gyeongnam region. And accordingly, this researcher examined such strategy styles that dental lab managers, chief technicians and assistant technicians usually have. Results of the study can be summarized as follows. First, out of the self-leadership strategy styles, most remarkably found among the professional of dental technology was constructive thought strategy, followed by behavior-focused and natural reward strategies in order. In general, therefore, the professionals strongly tend to make their thoughts that can a positive effect on their work performance or in a constructive way. In other words, professional dental technicians are more likely to make efforts to persuade or persuade themselves to change their own unreasonable confidence or negative process in more positive way. Second, the extent to which constructive thought strategy is perceived was not different among dental lab managers, chief technicians and assistant technicians. While, behavior-focused and natural reward strategies were found most strongly perceived by dental lab managers, followed by chief and assistant technicians in order. This may be attributed to the fact that the higher professional dental technicians are in position, the higher they are in self-leadership, or in the ability to overcome crises by themselves and make their thought or behavior in a right way. Dental lab managers usually have lots of experiences in relation to behavior-focused or natural reward strategy. Therefore, they are very strongly capable of controlling themselves in order to overcome crises or make their thought or behavior in a right way. In contrast, assistant technicians are still having lots of trials and errors because they are less experienced and skilled. This suggests that chief technicians should make themselves fully capable as a medium that connects between dental lab managers and assistant technicians.

Purposes: This research is an empirical research to analyze the effect of self-leadership on the job satisfaction and organizational citizenship behavior and the mediating effect of psychological capital. Methods: This research investigates the effect of self-leadership and psychological capital on job satisfaction and organizational citizenship behavior of public health workers. The analysis was carried out to 4 local medical staffs in Chungcheongnam-do province, which distributed 330 copies and recovered 313 copies (94.8% recovery) and analyzed 304 copies (effective response rate 92.1%). Findings: First, causality was found in self-leadership and psychological capital. Second, it was found to have a significant effect on psychological capital and job satisfaction. Third, psychological capital was found to have a significant effect on organizational citizenship behavior. Fourth, psychological capital has a positive effect on both Self-leadership's behavior-oriented strategy, natural reward strategy, and strategic thinking pattern strategy. In the job satisfaction relationship, there was a partial mediating effect. Fifth, psychological capital has a positive effect on both self-leadership and organizational citizenship behavioral behavior-oriented strategy, natural reward strategy, and strategic thinking pattern strategy. The organizational citizenship behavioral relationship was found to have a partial mediating effect. Practical Implications: Taken together, the results indicate that the members of the four public health care organizations run by Chungcheongnam-do have a high weight on the natural reward strategy of achieving job satisfaction through the pleasures of doing their favorite activities or jobs.

본 연구의 목적은 경영자의 능력과 경영자 성과-보상 민감도 간의 관련성에 보고이익전략이 미치는 조절효과를 살펴보는 것이다. 경영자의 보고이익전략에 따른 경영성과의 조정 방향은 상향조정과 하향조정 모두 발생할 수 있으며, 상향 조정과 하향 조정에 따라 경영자 보상에 미치는 영향이 차별적일 것으로 예상되어 분석한 결과, 과대보고를 위한 보고이익전략은 기대와 동일하게 상향조정 된 경영성과에 따라 보상을 지급하였으므로 성과에 근거한 차별적인 보상이 지급되지 않는 것으로 확인되었다. 반면에 과소보고를 위한 전략은 성과에 근거한 성과-보상 민감도를 감소시키는 것으로 나타났다. 과소보고전략은 경영자의 능력에 따른 보고전략의 수행에 대하여 추가적인 보상이 지급되어 보상의 수준은 증가하지만, 이러한 유형의 보상이 경영자의 실제 성과와는 무관하므로 성과-보상 민감도를 감소시킬 것이라는 가설을 지지하며, 보고이익전략에 따른 경영성과의 상향 및 하향 조정에 대해 차별적인 보상이 이루어진다는 것을 간접적으로 확인한 결과이다.

Purpose - This paper attempts to derive effective performance-reward strategies for SMEs to raise the valence for their employees while using their relatively limited resources, which is one of the primary concerns raised by SME CEOs. Research design, data, and methodology - This paper draws on the four question items such as the financial/direct factors, the financial/indirect factors, the non-financial/direct factors and the non-financial/indirect performance-reward factors to shed light on the most important factors and aspects that need improving, using the AHP and IPA. Results - The overall findings on the SMEs' performance-reward factors of interest here are indicative of the need for rectifying their performance-reward systems. Conclusions - SMEs' performance-reward factors of interest here are indicative of the need for rectifying their performance-reward systems. In particular, despite the fact that SMEs can hardly offer high wages or bonuses as large enterprises do, the expectancy theory suggests it is better to reward employees as per a valid common system, while the equity theory underscores the need to maintain and reinforce the fairness in distribution, procedures and interactions.

The optimal price strategy selection of two bounded rational cognitive mobile virtual network operators (MVNOs) in a duopoly spectrum sharing market is investigated. The bounded rational operators dynamically compete to sell the leased spectrum to secondary users in order to maximize their profits. Meanwhile, the secondary users' heterogeneous preferences to rate and price are taken into consideration. The evolutionary game theory (EGT) is employed to model the dynamic price strategy selection of the MVNOs taking into account the response of the secondary users. The behavior dynamics and the evolutionary stable strategy (ESS) of the operators are derived via replicated dynamics. Furthermore, a reward and punishment mechanism is developed to optimize the performance of the operators. Numerical results show that the proposed evolutionary algorithm is convergent to the ESS, and the incentive mechanism increases the profits of the operators. It may provide some insight about the optimal price strategy selection for MVNOs in the next generation cognitive wireless networks.

본 논문은 보상함수 수정을 통해 보다 완벽한 DSA(Dynamic Spectrum Access)를 수행하는 새로운 방법을 제시하였다. POMDP(Partially Observable Markov Decision Process)는 미래의 스펙트럼 상태를 예측하는데 사용되는 알고리즘으로서, 그 중 보상함수는 스펙트럼을 예측하는데 있어 가장 중요한 부분이다. 그러나 보상함수는 Busy 및 Idle의 두 가지 상태만 갖고 있기 때문에 채널에서 충돌이 발생하게 되면 보상함수는 Busy를 반환함으로써 2차 사용자의 성능을 감소시키게 된다. 따라서 본 논문에서는 기존의 Busy를 Busy 및 Collision 의 두 상태로 구분하였고, 이렇게 추가된 Collision 상태를 통해 2차 사용자의 채널 접근 기회를 보다 향상시킴으로서 데이터 전송율을 증대시킬 수 있도록 하였다. 또한 본 논문은 새로운 알고리즘의 신뢰도 벡터를 수학적으로 분석하였다. 마지막으로 시뮬레이션 결과를 통해 개선된 보상함수의 성능을 검증하고, 이를 통해 새로운 알고리즘이 CR 네트워크에서 2차 사용자의 성능을 향상시킬 수 있음을 보인다.

In this research, we study the problem of opportunistic spectrum access (OSA) in a time-varying environment with fading channels, where the channel state is characterized by both channel quality and the occupancy of primary users (PUs). First, a finite-state Markov channel model is introduced to represent a fading channel. Second, by probing channel quality and exploring the activities of PUs jointly, a two-dimensional partially observable Markov decision process framework is proposed for OSA. In addition, a greedy strategy is designed, where a secondary user selects a channel that has the best-expected data transmission rate to maximize the instantaneous reward in the current slot. Compared with the optimal strategy that considers future reward, the greedy strategy brings low complexity and relatively ideal performance. Meanwhile, the spectrum sensing error that causes the collision between a PU and a secondary user (SU) is also discussed. Furthermore, we analyze the multiuser situation in which the proposed single-user strategy is adopted by every SU compared with the previous one. By observing the simulation results, the proposed strategy attains a larger throughput than the previous works under various parameter configurations.

Reward-based crowdfunding is a funding platform that allows funds to be raised to early operators who have lack of funds, and is seen as an outstanding infrastructure that is going to lead the fourth industrial revolution in that it is a field of realization of new technologies and creative ideas by start-ups. Reward-based crowdfunding has grown in line with the trend of the fourth industrial revolution, and funding success cases are taking place in various industries that culture/art to technology/IT, including as a new means of knowledge management in a rapidly changing industrial environment. The study focused on the fact that consumer's donation purposes may also vary depending on the category of projects classified as reward-based crowdfunding. Because consumer payment decisions and motivation of consumer purchasing behavior are classified according to the purpose of purchase, the previous papers that the goal gradient effect that the main motivation of consumer donation for reward-based crowdfunding introduced vary depending on project category of utilitarian and hedonic. In this study, consumer's daily donation data is collected by Indiegogo which is a leading reward-based crowdfunding company using web-crawling and the model was defined as propensity score matching (PSM) and random effect model. The results showed that the goal gradient effect occurred in utilitarian project category, but no goal gradient effect for the hedonic project category. Furthermore, this paper developed the study of motivation of consumer donation and contributes theoretical foundation by the results consumer donation may vary depending on the project category; also, this paper has implications for an effective marketing strategy depending on the project category leaves real meaning to the projector.
