The purpose of this paper is to explore a concept that has been less examined in empirical research on school organization, namely Network Learning Capacity (NLC). It is proposed that teachers’ professional networks enhance teachers’ individual NLC. This process leads to a formation of professional community (PC) and therefore affects the level of organizational learning (OL).

The quantitative study with multiple methods comprising social network analysis, confirmatory factor analysis and structural equation modeling was conducted. Data were collected from a school implementing the International Baccalaureate (IB) programs in Taiwan.

Findings suggest that certain network positions were crucial in forming NLC on instruction. In addition, reflective dialogue, shaped by NLC, is the key component in establishing learning in this case school.

As the first of its kind in an educational context, the study highlights the linkages between network position and the development of professional learning community, which is mediated through NLC. This study contributes to illuminating the process of how PC practices and OL can be promoted in schools.

The number of older adults in Thailand is currently increasing. To create the appropriate oral health service for this age group requires an understanding of the factors that are associated with their dental service utilization. This study aimed to determine the associations between social backgrounds, oral behaviors and dental service utilization among Thai older adults.

This was a cross-sectional study on a representative sample of older adults in the 8th Thai National Oral Health Survey (TNOHS). Data of 4,130 Thai older adults were collected through interviews. The association between social backgrounds, oral behaviors and dental service utilization were investigated using chi-square and logistic regression models.

Of the older adults aged 60–74 years old, 38.4% had used dental services in the last 12 months. Smokers used dental services the least (32.1%). Location, income, education and social welfare were significantly associated with dental service utilization. Among the oral behaviors evaluated, smoking was significantly associated with low dental service utilization.

Thai older adults with a poor social background including location, income, education, entitlement to the Universal Coverage Scheme (UCS) and smoking made less use of dental services.
