The purpose of this study was to examine the effects of repetitive horticultural activities on the dexterity and out of seat behaviors of 5 years old children. Horticultural activities were conducted from March 3 to April 21, 2017, once a week for 20 minutes per session, a total of 8 sessions. The program was divided into first half (Sessions 1-4) and second half (Sessions 5-8) and horticultural activities were repeatedly carried out. In Sessions 1 and 5, kindergarteners transplanted succulent plants into pots, and observed and managed the plants daily. From Session 2 to 4 and from Session 6 to 8, kindergarteners watered and observed the succulent plants planted in Sessions 1 and 5 and they put flowers on a floral foam (10 × 10 × 10 cm). This study conducted the O'Connor Tweezer Dexterity Test in which the number of pins subjects inserted for 30 seconds was counted, and there was a significant difference (p =.000) in the dexterity of the kindergarteners after performing horticultural activities in the result of the repeated measures design ANOVA. The time kindergarteners left their seat for the first time while participating in horticultural activities for 20 minutes was measured using a stopwatch in each session. There was a significant difference (p =.000) in the ANOVA test in changes in their out of seat behavior in Session 8. In addition, there was no significant difference in the dexterity and out of seat behavior of kindergarteners from Session 2 (p =.364, p =.975, respectively) to Session 3 (p =.055, p =.283), but there was a significant difference from Session 4 (p =.042, p =.009) to Session 8 (p =.000, p =.000) as sessions were repeated.

Objectives: The purpose of the study was to analyze the association between indirect vision skills and neck, shoulder, and back pain in dental hygienists. Methods: This cross-sectional study included 85 dental hygienists working full-time at dental clinics. A survey was performed for musculoskeletal symptoms in the neck, shoulders, and back of the subjects. The O'Connor tweezer dexterity test was performed using a mirror to evaluate their indirect vision skills. For statistical analyses, the t-test and one-way analysis of variance were performed. Results: The neck was the most common region of musculoskeletal pain (89.4%). The most intense pain was experienced in the neck (70.6%) and right shoulder (60.0%). Neck pain (20.0%) caused the most interference with clinical practice. Indirect vision skills were lower in the group with severe pain in the left shoulder or with high interference in work due to the left shoulder pain (p=0.026 and p= 0.017, respectively) or right shoulder pain (p=0.004). Conclusions: In this study, neck pain was a major musculoskeletal symptom among dental hygienists, and poor indirect vision skills were associated with the development of shoulder pain. Therefore, to prevent such musculoskeletal symptoms, dental hygienists should become proficient in indirect visualization, which enables a balanced and neutral posture.
