Objectives: This study aimed to evaluate the relationship between oral health professionals' knowledge, attitude, and practice with regard to infectious waste management and to identify related factors influencing it. Methods: The study comprised of 219 oral health professionals from select dental clinics and public health centers recruited between August 25, 2016 and September 5, 2016, who agreed to participate in the study with full understanding of the study objectives. A self-reported questionnaire was administered, which consisted of 22 items on knowledge of infectious waste management, 9 items on attitude, and 16 items on practice. Data were analyzed using Pearson's correlation coefficient and stepwise multiple regression analyses. Results: The age, knowledge, and clinical attitude of oral health professionals significantly correlated with waste management practice. Specifically, infectious waste management practice improved with increasing age, a greater level of knowledge, and a more positive clinical attitude. Additionally, the standardized regression coefficient demonstrated that, of these three factors, clinical attitude more strongly correlated with effective waste management practice, followed by age and level of knowledge. Conclusions: These results indicated that oral health professionals had a low level of knowledge regarding infectious waste management, and a more positive clinical attitude resulted in better practices. Therefore, the development of detailed and active education guidelines and strategies are needed to enhance the attitude, knowledge, and practice of oral health professionals with regard to infectious waste management.

The main purpose of this study is to assess the relationship between communication satisfaction and group creativity. To achieve this purpose, this study has two objectives. First, I will identify the relationship between the satisfaction of communication and idea creation. Second, the relationship between communication satisfaction and problem solving activity will be statistically tested. The major findings of the study can be summarized as follows: First, Statistically significant positive relations were found between the communication satisfaction and idea creation. Especially, sub-construct for supervisor communication$({\beta}=0.14,\;p<.05)$, quality of media$({\beta}=0.13,\;p<.05)$, individual feedback$({\beta}=0.36,\;p<.001)$, organizational prospect$({\beta}0.31,\;p<.001)$ showed the statistically significant positive(+) relationship with construct in idea creation. Second, the measurement of communication satisfaction had showed statistically significant relationship with the problem solving activity. Especially, communication with supervisor$({\beta}=0.21,\;p<.05)$, quality of media$({\beta}=0.21,\;p<.001)$, organizational prospects$({\beta}=0.22,\;p<.001)$, and communication with subordinate$({\beta}=0.37,\;p<.001)$ showed the significant positive(+) relationship with problem solving activity construct. These consequences suggest that communication satisfaction of employee is effective in the improving the group creativity in organization. In the conclusion, this study present the satisfaction factor of employee communication as a incremental factor of group creativity.

The objective of this study was to examine the relationship between meat quality attributes and the changes of sarcoplasmic protein acetylation and myofibrillar protein acetylation in lamb longissimus thoracis et lumborum muscles at different postmortem phases. Protein acetylation, color, pH, shear force, myofibril fragmentation index and cooking loss were measured. The total level of acetylated sarcoplasmic proteins showed a negative relation with pH, a positive relation with a^*, b^* and cooking loss at the pre-rigor phase. Sarcoplasmic proteins acetylation affected postmortem pH by regulating glycolysis, which in turn affects color and cooking loss. The total level of acetylated myofibrillar proteins showed a positive relation with shear force at the pre-rigor phase. Myofibrillar proteins acetylation affected meat tenderness by regulating muscle contraction. This study indicated that acetylation played a regulatory role of meat color, water-holding capacity, and tenderization process at early postmortem.

Patient revisit to used hospital is a key factor in determining a health care organization's competitive advantage and survival. This article examines the relationship between customer's satisfaction and his/her revisit associated with three different methods which are the Chi Square Automatic Interaction Detection(CHAID) for segmenting the outpatient group, logistic regression and neural networks for addressing the outpatient's revisit. The main findings indicate that the important factors on outpatient's revisit are physician's kindness, nurse's skill, overall level of satisfaction, hospital reputation, recommendation, level of diagnoses and outpatient's age. Among these ones, physician's kindness is the most important factor as guidelines for decision of their revisit. The decision maker of hospital should select the strategy containing the variable amount of the level of revisit and size of outpatient's group under the constraint on the hospital's time, budget and manpower given. Finally, this study shows that neural networks, as non-parametric technique, appear to more correctly predict revisit than does logistic regression as a parametric estimation technique.

This study explored how intrinsic and extrinsic motivation relates to achieving creativity at project work. We were interested in differences in how motivational factors relate to creativity. Using data from the 98 engineers and researchers employed by a variety of companies, principal components factor analysis with marimax rotation was performed on the data. We examined effects of the moderate variables the intrinsic and extrinsic motivation and creativity relationship. The results indicate of positive mental involvement, the time and the resource constraints relates positively to creativity in organizations and that the relationship is a simple linear one. These outcomes are significantly related to intrinsic motivation and the creativity. In additions, extrinsic motivation is related to less the creativity. Our survey findings are also consistent with other sources of knowledge on the topic. Our results suggest that there are two different role: mental involvement, time and resources constraints, both of which predict creativity, and external control and extrinsic motivations reduce to creativity.
