Smart pig farm which is based on IoT has been widely adopted by many pig farmers. In order to achieve optimal control of smart pig farm, the relation between environmental conditions and performance metric should be characterized. In this study, the relation between multiple environmental conditions including temperature, humidity and various performance metrics, which are daily gain, feed intake, and MSY, is analyzed based on data obtained from 55 real pig farm. Especially, based on preprocessing of data, various regression based machine learning algorithms are considered. Through performance evaluation, we show that the performance can be predicted with high precision, which can improve the efficiency of management.

Strong construction and real estate firms will contribute more to the country's GDP by contributing to the industry's development. The purpose of this study is to examine the factors that influence the performance of the construction and real estate sectors in Vietnam. A survey of 200 construction and real estate firms in different areas was conducted from 2020 until the end of 2021. Following the removal of errors, the author got 196 replies, 6 of which were invalid, leaving 190 votes for quantitative analysis. The research findings show that elements such as (1) senior executives' commitment to the organization, and (2) the ability to use technology have a positive and significant impact on firm performance when using advanced econometric analysis. Furthermore, in the case of Hanoi, Vietnam, business relationships have a positive impact on firm performance. Training and development, as well as the working environment and incentives, have little effect on the profitability of construction and real estate firms. Finally, the research also has some recommendations and limitations for the construction and real estate sector.

The purpose of our study was to examine the effects of dietitians' sanitation training performance on the sanitation knowledge and management practice level of culinary employees. We developed a questionnaire to measure the sanitation knowledge and management practice level of culinary employees and the sanitation training performance of dietitians. The questionnaire was completed by 53 dietitians and 337 culinary employees working in food service in the Chungbuk Province. We found that the sanitation training performance of dietitians had a significant positive affect on the sanitation knowledge and management practice level of culinary employees. There was also a correlation between sanitation knowledge and the management practice level of culinary employees. We conclude that sanitation training performance by dietitians is an effective method of improving the sanitation knowledge and management practice level of culinary employees. Thus, we suggest strengthening the sanitation training programs given by dietitians to improve food hygiene and safety in the foodservice industry.

Purpose: This study empirically investigates the effect of collaborative communication and information sharing on the supply chain performance of South Korean pharmaceutical companies. Specifically, it understands the importance collaborative communication and suggests a method for investigating communication in academic research on the pharmaceutical industry. Investigating this sector is crucial because the importance of the pharmaceutical industry is increasing globally against the background of the Covid-19 pandemic. Research design, data, and methodology: A questionnaire was administered to employees of South Korean pharmaceutical companies and 244 valid responses were used for the statistical analysis. Additionally, structural equation modeling was used to measure the relationships between the observed and latent variables. Results: Collaborative communication has a positive effect on information sharing. However, information sharing, unlike collaborative communication, does not exhibit a significant positive relationship with supply chain performance. These results indicate that it is important to communicate effectively in the supply chain rather than strive for the right type of information sharing. Conclusions: Consumers and retailers within the supply chain should continue to strive for candid communication. This study is meaningful, as it empirically tests the relationships between collaborative communication, information sharing, and supply chain performance in the South Korean pharmaceutical industry.
