It is important that desktop grids should be able to aggressively deal with the dynamic properties that arise from the volatility and heterogeneity of resources. Therefore, it is required that task scheduling be able to positively consider the execution behavior that is characterized by an individual resource. In this paper, we implement a log analysis system with REST web services, which can analyze the execution behavior by utilizing the actual log data of desktop grid systems. To verify the log analysis system, we conducted simulations and showed that the resource group-based task scheduling, based on the analysis of the execution behavior, offers a faster turnaround time than the existing one even if few resources are used.

The purpose of this study is to explore the factors that influence the purchase of AI speakers in China. We integrate the Unified Theory of Acceptance and Use of Technology (UTAUT) and Task-technology fit (TTF) model into one model and put forward assumptions. According to the characteristics of AI speakers, we selected 6 independent variables, such as Performance Expectation, Effort Expectation, Social Influence, Facilitating Conditions, Task and Technology-characteristics. The final impact on purchase behavior is evaluated through Task-technology fit and purchase intention. After counting 478 samples, through SPSS22.0 and AMOS analysis, hypotheses have been proved by strong experimental data, except facilitating conditions. These results also imply that improving the technical level of AI speakers and enhancing consumers' purchasing intention are the central line of marketing. Based on this, we put forward several suggestions to marketers, including strengthening the research and development of AI speaker technology, and building a circle of friends of AI speakers.

In this paper, task control architecture is proposed for a mobile robot with behaviors based on cognition theory to endow the robot intelligence. In the task control architecture, task manager is introduced especially for the management of computational resource. The management is based on classical RMS (Rate Monotonic Strategy), but with online rate modulation strategy. The rate modulation is performed using the value variances of behavior execution for the task. Because the values are based on natively uncertain sensor information, they are modeled using PDF (probability Density Function). As a rate modulation process, the range of the rate modulation is defined firstly by real-time constraints of RMS and discrete control stability of behaviors. With the allowable range, rate modulations are performed considering harmonic bases to maintain utilization bound without decrease. To evaluate the efficiency of the proposed rate modulation strategy, a simulation test is performed to compare the efficiency between the control architecture with the proposed strategy and previous one. A performance index with the formalization of propensity of resource allocation is proposed and utilized for the simulation test. To evaluate the appropriateness of the performance index, the performance index is compared with practical one through a practical simulation test.

This study developed an experience-based economic education program and examined its effects on young children's economic concepts and purchasing behavior. Subjects were 60 5-year-old kindergarteners assigned to an experimental or a control group. Instruments for pre- and post-tests were the Economic Concept Task (Laney, 1995) and the Purchasing Behavior Task (Jang, 2004). Experimental group children participated in the economic education program for 5 weeks; control group children listened to economic stories. Differences between pre- and post-test in the experimental group showed that the economic education program was effective in development of concepts of scarcity, opportunity cost, resource/production, goods/services, and complements/substitutes. Children's purchasing behavior changed partially after application of the program.

The study was conducted to compare organizational innovation depending on the leadership type of middle managers in general hospital. Moreover, the study was also to prove whether employees'readiness causes any differences to the link between leadership and organizational innovation. The result is based on 769 sheets of survey paper answered by administrations and nurses working at general hospitals or the same level of hospitals located in the metropolitan area. The methods of analysis used are as follows: reliability analysis, frequency analysis, t-test, ANOVA, multiple regression analysis, and hierarchical regression analysis. Main results of the study can be summarized as below. First, by analyzing the influence of task-behavior leadership on organizational innovation, R squre on knowledge management which is organizational innovation factor was 12.5%, R squre on creativity was 9.1%, and R squre on innovation behavior was 10.3%. Regression model appeared to be statistically significant as well. Both task-behavior and relationship-behavior leadership have influence on organizational innovation and it is learned that relationship-behavior leadership has a bigger influence on all the organizational innovation factors. Second, moderating effect of the employee's readiness is examined in terms of the link between leadership and organizational innovation. As a result, the member's readiness had positive influence when it comes to the link between leadership and organizational innovation. Also, after verifying moderating effect of readiness (ability/willingness), this study shows that ability readiness has positive influence on the link between task-behavior(or relationship-behavior) leadership and creativity, and innovation behavior while willingness readiness positively influences the link between task-behavior(or relationship-behavior) leadership and creativity & innovation behavior. To summarize results of the study, this study shows that the members who possess high readiness also have high organizational innovation, which promises their positive role in a group.

The purpose of this study is to investigate the relationships between knowledge sharing antecedents and knowledge sharing intention in a financial institute and knowledge sharing behavior, knowledge sharing behavior and knowledge sharing performance. This paper first reviews the influencing factors of knowledge sharing and presents the research framework on knowledge sharing with categorized four factors such as structural factors, relational factors, personal and task characteristics. Based on a research framework, survey analysis was conducted with financial institution members. This paper examined the relationship between antecedents of knowledge sharing and knowledge sharing intention, knowledge sharing intention and knowledge sharing behavior. Also it analyzed the relationship between knowledge sharing behavior and the knowledge sharing performance. As a result, the paper suggested that the knowledge sharing intention consist of two dimensions. The first is voluntary knowledge sharing intention. The second is solicited knowledge sharing intention. The former has a significant positive relationship with the innovativeness, communication, personal creative propensity and perception of the knowledge sharing. The later has a significant positive relationship with the task interdependence but has a significant negative relationship with the knowledge sharing evaluation system. Knowledge sharing intention has a significant positive relationship with the knowledge sharing behavior. Also knowledge sharing behavior has a significant positive relationship with the knowledge sharing performance. Finally, the implications and limitations of the study are discussed.

Individual adoption and sustained usage of information technology(IT) are crucial prerequisites for exploiting IT as integral components of organizational work. Previous studies on technology adoption in workplace suggest that acceptance behavior is influenced by a variety of factors such as individual differences, social influences, beliefs, attitudes, and situational influences. In this paper, we introduce a research model to predict the usage behavior of intranet in workplace and also explain the causal relationships among variables. Based on the survey of 333 intranet users, this study uses structural equation model with LISREL 8.12. This study suggests several major results from surveys and analysis from them. Perceived use is influenced by intranet experience, task equivocality, organizational support, and perceived ease of use, Experience and organizational support determine perceived ease of use. Task equivocality, task interdependence, and organizational support have positive effects on subjective norm. On the other hand, present usage, which is a dependent variable in this model, is influenced by perceived use, experience, task interdependence, and organizational support.
