Tooth extraction is a common procedure in dentistry that can result in wounds to the soft and hard tissues of the alveolar process, thereby triggering the healing process. The wound healing process is often complicated by several factors, leading to delayed wound healing. The principles of wound healing involve four phases: hemostasis, inflammation, proliferation, and remodeling. This study aimed to determine the effect of black crab (Scylla serrata) chitosan gel on three-dimensional socket response and fibroblast proliferation after tooth extraction in Wistar rats (Rattus norvegicus). In this study, chitosan material with a degree of deacetylation of 84.9% was used, thus exhibiting good biological properties in the wound healing process. This research is an experimental study with a post-test only with a controlled group design. The sampling technique used was purposive sampling, and the sample size was calculated using the Federer formula. Observations were made by measuring the mesial-distal, lingual-buccal, and socket depths using calipers and the UNC15 probe and observing the number of fibroblasts histologically on Days 1, 3, and 7. The results of the one-way ANOVA and post hoc LSD tests indicate significant outcomes in socket wound closure and fibroblast proliferation in the chitosan gel group. This study demonstrates that black crab (Scylla serrata) chitosan gel is effective in accelerating socket wound closure and stimulating fibroblasts in socket wounds after tooth extraction.


Keywords: tooth extraction, black crab chitosan gel, socket response, fibroblast.

A supply chain strategic decision-making framework is developed by characterizing this particular type of decision, determining its constraints and criteria, and establishing the relationship it holds with them. To develop the SC strategic decision framework, a literature review was conducted on existing characterization methodologies that had been identified. The decision-making framework outlined in this study consists of the following key components: strategic decision-making, identification of influencing factors, establishment of criteria, and the interplay between strategic decisions, criteria, and determining factors. This study establishes a context that facilitates obtaining inputs for multi-criteria decision techniques, which significantly facilitates the work of strategic decision-makers. The novelty of this work is that it develops a strategic decision structure that links the criteria, variables, and theoretical and methodological frameworks in which the decision is epistemologically supported.


Keywords: decision framework, strategic decisions, supply chain.

This study investigates the effects of climate change on rice yield in Vietnam’s Mekong River Delta. Using provincial-level data spanning 2010-2019, the research employs feasible generalized least squares to address heteroskedasticity. Findings reveal distinct impacts of climate change on rice yield between the winter-spring and summer-autumn crops. While sunshine hours and land area positively influence yield in both seasons, the highest water level affects only the summer-autumn crop. Conversely, average salinity negatively affects both crops, with a 1-g/liter increase reducing yields by 0.535 quintals/ha in winter-spring and 0.101 quintals/ha in summer-autumn. Although rising humidity diminishes winter-spring crop yield, it does not affect the summer-autumn crop. Moreover, scaling up leads to increased rice productivity in both seasons. These insights underscore the importance of climate-resilient agricultural strategies in the Mekong River Delta. The findings can help local governments and policymakers concretely quantify the impact of climate change on rice productivity. Therefore, appropriate policies can be developed to address climate change to improve rice productivity and increase farmers’ incomes.


Keywords: climate change, rice yield, sustainability, Mekong River Delta.

This study examines the impact of contractionary monetary policy on inflation in Bangladesh using time series data for 1987–2022. Money supply, interest rate, and exchange rate are taken as independent variables to show their effect on inflation. The ADF test is used to test the stationarity of the variables in the model, and all the variables are stationary at the first difference. As a result, Johansen’s co-integration techniques are used, revealing a co-integrated equation in the model. Therefore, the vector error correction model (VECM) is used for the estimation. The VECM estimation shows that the coefficient of error correction with the inflation rate as a dependent variable is negative and statistically significant at 5%, implying a robust long-run relationship between money supply, interest rate, exchange rate, and inflation rate. In the short run, bidirectional causality exists between the money supply and inflation only at the first lag. Moreover, the study found no overall short-run significant causality between the money supply, interest rate, exchange rate, and inflation. The novel approach of this study lies in its comprehensive analysis of the intricate relationship between monetary policy instruments and inflation dynamics in Bangladesh.


Keywords: contractionary monetary policy, inflation, vector error correction model.

This study evaluates the effectiveness of body measurement training for community health workers (CHWs) using a modified length board. The research is quasi-experimental, with a pretest and posttest non-equivalent group design. A total of 60 CHWs measured the length of 80 children in the intervention and control groups. The effect of the intervention was determined using the chi-square test. After the intervention, there was a significant change in CHWs’ skills in positioning children, reading measurement results, and determining nutritional status. There were few differences in measurement results between the length board and the distance measuring tool. Overall, body measurement training with the modified length board as the main medium effectively improves CHWs’ skills in measuring height and determining nutritional status.


Keywords: community health worker, nutrition status, anthropometric training, children.
