Recently, a great deal of corporations have adopted knowledge management system with eagerness to enhance the company competitiveness. However, since the main feature of knowledge management system is not just a simple information system but another entity creating intangible assets tailed "knowledge", we need to develop a new approach to investigating the performance and acceptance of knowledge management systems from a perspective allowing knowledge-sensitive constructs. In this regard, we develop new constructs like knowledge schema and several knowledge circulation-related activities. As a research model, we adopt a famous technology acceptance model or TAM by Davis (1989), and extend it into incorporating knowledge schema. With the statistically valid and usable questionnaire survey data collected from 886 respondents in a big corporation typically using knowledge management system, we induced a robust result empirically, saying that knowledge schema and knowledge circulation activities are valid determinants of performance and acceptance of knowledge management systems.

The purpose of this study is to explore the variables of knowledge, acceptance of theory of evolution and epistemology that could be keys for teaching and learning the theory of evolution within school contexts, and to suggest instructional tips for teaching evolution in relation to the grade levels of education. This cross-sectional study examined the grade level differences (8th, 11th, and preservice teachers) of four variables: evolutionary knowledge; acceptance of theory of evolution; and both domain-specific epistemology (nature of science in relation to evolution) and context-specific epistemology (scientific epistemological views) and their relationships. This study, then, built conceptual models of each grade level students' acceptance of theory of evolution among the factors of evolutionary knowledge and epistemology (both domain-specific and context-specific). The results showed that the scores of evolutionary knowledge, evolution in relation to NOS, and scientific epistemology increased as the grade levels of education go up(p<.05) except the scores of acceptance of theory of evolution(p>.05). In addition, the 8th graders' and the 11th graders' acceptance of evolutionary theory was most explained by 'evolution in relation to NOS', while the preservice teachers' acceptance of evolutionary theory was most explained by evolutionary knowledge. Interestingly, 'scientific epistemological views' were only included for the 8th graders, while evolutionary knowledge and 'evolution in relation to NOS' (context-specific epistemology) were included in explaining all the level of students' acceptance of evolutionary theory. This study implicated that when teaching and learning of the theory of evolution in school contexts, knowledge, acceptance of evolutionary theory and epistemology could be considered appropriately for the different grade levels of students.

As web technologies evolve and so-called Web 2.0 technologies appear, collective intelligence is being applied in widespread areas. In general, mass collective intelligence like Wikipedia is created, revised, and managed by anonymous participants in an uncontrolled system. Thus, the knowledge provided by mass collective intelligence may be distorted, and may not be true, which may affect the user acceptance behavior. However, there have been few academic studies that analyzed the factors that affect user acceptance of mass collective intelligence, and their relationships. Under this academic background, we develop a model to examine how mass collective intelligence is accepted by users. The theoretical model is validated through an online survey of the Wikipedia users from three universities in Korea. The results reveal that the users will have positive attitude towards adopting mass collective knowledge when they perceive that the knowledge from mass collective intelligence is useful. We also find that the perceived usefulness of the knowledge is affected by perceived knowledge quality and trust in knowledge contributors. The results also suggest that perceived knowledge quality is determined by perceived level of collaboration, perceived objectivity, and recipient expertise, whereas trust in knowledge contributors is determined by natural propensity to trust and perceived objectivity. Theoretical and practical implications about mass collective knowledge are discussed.

In the past two decades, there has been an increasing interest in project knowledge management, as knowledge is a crucial resource for project management success. Knowledge capture and sharing are two effective project management practices. Capturing and sharing project knowledge has become more efficient due to technological advances. Nevertheless, present technologies face several technical, functional, and usage obstacles and constraints. Thus, Blockchain technology might provide promising answers, yet, there is still a dearth of understanding regarding the technology's proper and practical application. Consequently, the goal of this study was to fill the gap in the literature about the adoption of Blockchain technology and to investigate the project stakeholders' acceptance and willingness to utilize the technology for capturing and sharing project knowledge. Due to this inquiry's exploratory and inductive characteristics, qualitative research methodology was used, namely the Grounded Theory research approach. Accordingly, eighteen in-depth, semi-structured interviews were conducted to collect the data. Concurrent data collection and analysis were undertaken, with findings emerging after three coding steps. Four influencing factors and one moderating factor were identified as affecting users' acceptance of Blockchain technology for capturing and sharing project knowledge. Consequently, the results of the study aimed to fill a gap in the existing literature by undertaking a comprehensive analysis of the unrealized potential of Blockchain technology to improve knowledge capture and sharing in the project management environment.

Knowledge is a fundamental assets, therefore, the ability to create, acquire, integrate, and share knowledge has emerged as a fundamental organizational capability(Sambamurthy and Subramani, 2005). This apaper reports the results of an empirical study investigating the factors of acceptance and the moderating role of resistance in Knowledge Management Systems(KMS). The research model is based on the theory of planned behavior(TPB) and technology acceptance model(TAM). It includes the perceived usefulness instead of attitude, subjective norm, perceived behavior control and intention of acceptance of KMS. Also, three external variables namely task-technology fit, organizational support, and perceived rewards are added. In the research model, all hypothrses of the baseline model and the moderating effects of resistance were found to be significant. The authors also of fred several implications based chi the findings.

Organizations have attempted to develop Knowledge Management Systems for achieving competitive advantage by effectively managing organizational knowledge. However, if Knowledge Management Systems are not user-oriented, organizations may not attain desired goals. That is, it must be utilized and accepted by organizational members to be successful systems. This study proposes an extended Technology Acceptance Model and empirically validates it. For that purpose, a research model is set UP that consists of antecedent variables, perception moderators, and intention to use the system. Empirical data analysis found significant relationships among research variables, as suggested in research hypotheses. The results of the analysis indicated that perceived usefulness, ease of use, job relevance and information quality should be considered as important factors in designing Knowledge Management Systems. In addition, perceived value, incentive, affect, self-efficacy, and image were found to influence the perception of users in the usage situation.

A survey was conducted to examine the effect of food irradiation education on college students' knowledge and acceptance of food irradiation. The instrument for the knowledge and acceptance of food irradiation was administered before and after food irradiation education, to 150 students majoring in food and nutrition or food technology in the Chungnam National University. Before the education approximately 93% of the respondents did not know that radioactivity dose not remain in food after irradiation; whereas, after education half of them thought that radioactivity dose not remain in irradiated food. Knowledge about food irradiation has improved through education. The education significantly increased all the mean scores of need for food irradiation and willingness to use irradiated foods for the six food groups (p<0.01). The education significantly decreased the mean scores of concern about the irradiated food for all the six food groups (p<0.01). Although the responses to irradiated foods are, in general, negative or neutral even after education, the mean scores of acceptance of the irradiated foods have improved through education in all the six food groups (p<0.01). In conclusion, this study showed that food irradiation education may positively affect the college students' knowledge and acceptance of food irradiation, and that the development of both the appropriate detection methods to identify irradiated foods and the education programs to enlighten the college students are needed.

This study was to investigate the effect of the education about general nutrition knowledge on the acceptance of TV food advertisements in adolescents. Twenty hours of nutrition related education in home economics classes were done during 3 months, to conveniently selected 784 first grade middle school students living in large and small cities and rural areas of Chungnam Province. The education effects were evaluated through questionnaire surveys before and after the education and their comparative analysis. Average TV watching time was $29.2\pm1.16$ hours per day, which was about one hour longer on weekends. Nearly half of the subjects watched TV mainly after 9 PM. After nutrition education, nutrition knowledge scores of total subjects were significantly increased from $7.73\pm2.16$ to $10.25\pm2.51$ with a full score of 16. Food attitude and food habit scores also significantly increased from $32.45\pm4.65$ (full score 50) to $33.93\pm4.68$ and from $36.20\pm5.70$ to $37.29\pm5.87$, respectively. The general acceptance of TV food advertisements scored $25.25\pm4.44$ (full score 40) before education and $26.90\pm4.55$ after education, which was significantly raised by the education. Acceptance scores of TV food advertisements showed significant positive relationships with the scores of nutrition knowledge, food attitudes, and food habits. In addition, TV watching time had negative relationships with nutrition knowledge, food attitudes, and food habits scores, but not with acceptance score of TV food advertisements. The above results suggested that school-based nutrition education improved slightly but significantly the attitude of accepting TV food advertisements maybe through increasing nutrition knowledge and making food attitudes and habits better. Nutrition education focused on the evaluation and acceptance of food advertisements are further needed to improve the TV food advertisement acceptance of adolescents.
