“…Soldiers, special forces, police officers, and bodyguards need to wear protective vests; however, many of them are reluctant to wear these vests because they are cumbersome to put on and remove. 18 If the vest fit is inappropriate, the design of the adjustment of the side waist size can be changed to improve the fit 19 ; however, the adjustment device is difficult to use and wear. 20 Protective vests should be easy and quick to put on and remove for rapid implementation in emergency situations, and they should provide maximum protection by perfectly fitting the body.…”

This study proposes the Auto-Fit Dial, which is suitable for high-speed fitting; it includes a function that can wind wire at high speed using an energy storage–release mechanism. The Auto-Fit Dial can store energy in advance in the spiral spring via the rotation of the knob cover, and it releases the stored energy to wind the wire when required by pushing the knob cover. Firstly, the concept design and working principle of the Auto-Fit Dial are explained. Next, a detailed design and structural stability analysis of the mechanical components are described based on the design formula and finite-element analysis. An Auto-Fit Dial prototype is manufactured according to the detailed design with the weight, diameter, and height of 9.7 g, 30.5 mm, and 16.7 mm, respectively. The maximum number of rotations is 5.2 turns, which can wind a wire up to a length of 320 mm. The pulling force applied when the Auto-Fit Dial pulls the wire is initially measured as 5.10 N. The time required to wind a 320 mm wire is 0.015 s, which results in an average speed of 21.33 m/s. Moreover, the Auto-Fit Sleeve is fabricated and applied to the arm sleeve to verify the utility of the Auto-Fit Dial, which combines wire and fabric. Finally, the Auto-Fit Vest is developed by applying a protective vest to the Auto-Fit Dial.

Musculoskeletal disorders occur frequently in industrial settings, and police officers in particular are at high risk of developing musculoskeletal disorders due to the nature of their work, but research on this is lacking. Therefore, the purpose of this study was to examine the prevalence and risk factors of musculoskeletal disorders according to the job functions of police officers. A survey was conducted, targeting active-duty police officers, and data were collected from 4268 respondents who answered all items on the questionnaire. As a control group, we used the general population dataset from the 2020 National Health and Nutrition Examination Survey conducted in Korea. The survey included general information such as gender, age, working hours, and type of work. It also investigated medical utilization, including the frequency of medical visits and hospitalizations. The assessment of musculoskeletal disorders was analyzed using pain NRS, VAS, SPADI, and ODI. The working characteristics of police officers were found to be more irregular in terms of working hours and involved a higher intensity of work activities compared with the general population. However, there was a lack of precise diagnoses and continuous treatment for these disorders. These results imply that police officers’ occupational characteristics are related to musculoskeletal disorders. Considering the direct relationship between police officers’ health and public safety, systematic evaluation and management of their musculoskeletal disorders are needed.
