The measurement results indicated that lighting levels remained at appropriate thresholds and compliant with prescribed standards. Furthermore, additional LED bulbs were installed to replace older bulbs in areas that had not yet been upgraded and where light intensity measurements failed to meet the standard criteria. This initiative helps enhance visual efficiency, reduce the risk of workplace accidents, and alleviate eye muscle fatigue, ultimately yielding positive effects on overall employee productivity.

The company requires new employees to undergo a health check-up based on risk factors within 30 days before starting work. This includes a physical examination and mental health assessment according to occupational medicine methods to determine the employees' health suitability and any potential impacts on their health when working with risk factors. The Occupational Safety and Health department assesses the risk factors for each job and establishes a Health Check-Up Matrix, which includes tests conducted by occupational physicians, such as hearing assessments for those working in noisy areas, lung function tests for those exposed to dust or chemicals, and blood chemical level assessments, among others. If any abnormalities are found during the examinations, the company will inform the employee of the results and provide initial guidance from professional nurses and safety officers. The examination results will also be reviewed by an occupational physician to assess the suitability of the employee for the assigned duties. If it is determined that the employee's health is not suitable for the type of work, the company will adjust their job responsibilities to align with the employee's physical condition.

The company arranged for the 2025 annual employee health check-ups in accordance with medical criteria and relevant laws to assess the overall health of employees and monitor health impacts potentially related to the nature of tasks or risk factors in the working environment. In 2025, a total of 682 employees participated in the annual health check-up, representing 94.98% of the total 718 eligible employees, who are individuals with a tenure of one year or more.

The health check-ups were conducted by licensed medical institutions and healthcare providers meeting professional standards, covering specified physical examinations as well as mental health screening and assessment by psychiatrists to ensure employees received both physical and mental care. The company notified employees of their health check results within 3 days of receiving them, allowing employees to manage their health in a timely manner. In cases where abnormal results or indications potentially related to operational risk factors were detected, the company notified and provided advice to the affected employees, and considered arranging re-testing or referrals to specialized medical facilities as appropriate.

Furthermore, the company utilized the aggregated health check data and risk-factor-based results to support occupational health risk assessments, review control measures, improve working environments, and establish guidelines for preventing work-related health impacts. In this regard, the company prioritizes the protection of employee health data, ensuring that such information is stored, used, and disclosed only as necessary and in strict accordance with the laws and guidelines governing personal data protection.
