To cope with the rapid changes in the corporate environment, the creation of innovative output through various forms of collaboration have been discussed. For open collaborations, contributors who distribute to various countries and cultures are able to share knowledge via the internet without physical rewards or responsibilities. In this study, we focused on the open source software project, which is a representative open collaboration. We investigated the factors that affect the knowledge contribution of developers of various countries within the open collaboration platform. Specifically, we investigated the open collaborative nature of multi-culture developers by dividing cultures according to collectivism and individualism. We collected data on 26,604 developers using a python based web crawler for GitHub which is an open source software development platform, and conducted cross-cultural study. This paper contributes to the field of knowledge management by suggesting various impacts of antecedents such as hireability, and information exposure on knowledge sharing according to culture.

In this research, we propose an automatic knowledge acquisition and composite knowledge expression mechanism based on machine learning and relational database. Most of traditional approaches to develop a knowledge base and inference engine of expert systems were based on IF-THEN rules, AND-OR graph, Semantic networks, and Frame separately. However, there are some limitations such as automatic knowledge acquisition, complicate knowledge expression, expansibility of knowledge base, speed of inference, and hierarchies among rules. To overcome these limitations, many of researchers tried to develop an automatic knowledge acquisition, composite knowledge expression, and fast inference method. As a result, the adaptability of the expert systems was improved rapidly. Nonetheless, they didn't suggest a hybrid and generalized solution to support the entire process of development of expert systems. Our proposed mechanism has five advantages empirically. First, it could extract the specific domain knowledge from incomplete database based on machine learning algorithm. Second, this mechanism could reduce the number of rules efficiently according to the rule extraction mechanism used in machine learning. Third, our proposed mechanism could expand the knowledge base unlimitedly by using relational database. Fourth, the backward inference engine developed in this study, could manipulate the knowledge base stored in relational database rapidly. Therefore, the speed of inference is faster than traditional text -oriented inference mechanism. Fifth, our composite knowledge expression mechanism could reflect the traditional knowledge expression method such as IF-THEN rules, AND-OR graph, and Relationship matrix simultaneously. To validate the inference ability of our system, a real data set was adopted from a clinical diagnosis classifying the dermatology disease.

It is the development of a mathematics teachers' teaching knowledge that manifests a mathematics teacher's professional knowledge growth. It is becoming a direct and effective approach of conversion of mathematical knowledge into the knowledge of mathematics teaching. Through the investigation, the study revealed that the knowledge conversion process of mathematics teachers in middle school is restricted by three aspects including eight factors. From this point, the authors have structured the path and model on influencing factors of middle school Mathematics Teaching Knowledge Conversion (MPCK), and discuss the mechanism of the transformation process.

Knowledge has been considered one of the important elements that determine our future. Competitive power of an enterprise has also been transformed from labor, capital, and technology-oriented to knowledge-oriented. Current construction environment is experiencing overall decrease of number of construction contracts due to opening of domestic construction market and economic slump, problems on methods of receiving orders/bidding, and change of costumers' attitude, which intensify competition, therefore many companies consider adopting knowledge management to secure their competitive power. However, there are difficulties in adopting knowledge management and increasing the use by establishing management plan, Performance Measurement, and knowledge maintenance system in reality. Therefore, this study is to provide assistance to successful realization of knowledge management by suggesting development plan of knowledge management that enables knowledge management more efficient with certain goals.

The purpose of this study was to investigate which variables predicted parenting efficacy. The variables of interest were demographic variables regarding both the infants and mothers, infant temperament and development, maternal parenting knowledge, parenting belief, and parenting stress. The subjects consisted of 260 infants and mothers. Data on infant's temperament, parenting knowledge, parenting belief, parenting stress and parenting efficacy were gathered through maternal self-reported questionnaires. Furthermore, infant development was assessed by classroom teacher. Data were analyzed by descriptive statistics, correlation and regression analyses. Our results indicated that infant's sociability and activity, parenting knowledge about emotional development, parenting beliefs emphasizing the role of nature in infant development, low parenting stress all predicted parenting efficacy.

The Knowledge Creation in early stages of new service development plays a critical role in the success of the service. The user is a crucial resource in creating knowledge in early stages of development, and user involvement is necessary. There are three roles the user can take part as in service development: informative, consultative, or participative. Based on these different roles, the process of knowledge creation varies. With this background, we proposed to investigate which creative processes need to be passed through in order to positively affect service development based on the role of the user in early stages of Internet service development. This case study was undertaken based on two new projects. The results of this study reveal the relationship between the knowledge creation process and user in early stages of development and at the same time provide guidelines regarding user involvement in actual service development.

Over the past decades, Bangladesh has fought poverty via labor-intensive industry and inclusive financing. The techniques assist underprivileged women in achieving self-sufficiency and encourage them to pursue independent endeavors. However, the majority of female entrepreneurs focused on four key company types: parlor, boutique, clothes, and fashion, all of which have limited access to financing. It was feared that their shortage of finance was hindering the growth of their company. The study's goal is to assess the effects of financial availability and knowledge on women's entrepreneurship development in Bangladesh via the lens of transformational leadership practices. A sample of 580 SMEs was considered for data collection with a structured questionnaire: a five-point Likert scale for getting responses from SMEs. The model coefficients with structural equation modeling revealed that financial accessibility plays a positive and statistically significant role in women's entrepreneurship development. Moreover, knowledge level established positive interlinkage with women's entrepreneurship development. Transformational leadership, which plays a mediating role in leadership practices, has been linked to the development of women's entrepreneurship indirectly and positively. As a result, support for knowledge creation and external financing must evolve and be made available to ensure women's sustainable development through entrepreneurial activities.
