Purpose : The study was designed to investigate analysis of kinematics of lower extremity in healthy adults during walking with external loads on trunk. Methods : Fifteen healthy adults were recruited and The subjects provided written and informed consent prior to participation. They walked on a ten-meter walkway at a self-selected pace with loads of 0, 5, 10, and 15kg. They completed three trials in each condition and kinematic changes were measured. A three-dimensional motion analysis system was used to analyze lower extremity kinematic data. The data collected by each way of walking task and analyzed by One-way ANOVA. Results : There were significant differences in hip and knee joint on saggittal plane at initial contact and preswing, and significant differences in ankle joint on transverse plane at preswing. Conclusion : These findings revealed that increased external loads were changed joint angles and influenced postural strategies because of kinematic mechanism and future studies is recommended to find out prevention from damage of activities of daily living.

Purpose: To evaluate changes in lower extremity muscle activity caused by high heeled shoe wearing during normal, brisk, and upslope walking. Methods: Twenty healthy young women (age, $23.9{\pm}2.47$) participated in this study. Muscle activities of the tibialis anterior, peroneus longus, gastrocnemius lateralis, gastrocnemius medialis, soleus, hamstring, vastus lateralis, and vastus medialis while walking normally, walking briskly, and walking up a slope. Results: When walking normally, the peroneus longus, gastrocnemius lateralis, soleus, and vastus lateralis evidenced higher activity when high-heeled shoes were worn (p<0.05). During brisk walking, the peroneus longus and gastrocnemius lateralis exhibited higher activity (p<0.05). Although the peroneus longus and vastus lateralis exhibited higher activity when walking up an incline with high-heeled shoes, the activity levels of the tibialis anterior and gastrocnemius medialis were lower (p<0.05). Conclusion: The results of this study demonstrate that increased heel height substantially reduces muscle effort when walking up a slope. From a therapeutic perspective, it is possible that using high heeled shoes over a short period might enhance muscle activity of ankle evertor, although it can cause mediolateral muscle imbalances in the lower extremities.

This study examined the personal and relational factors influencing the formation of body image among older persons. Aging-rel￡lted physical changes, health, marital relationship, cognitive age, and moods were personal and relationship factors explained for influence on the body image of older persons. Data were collected via a mail survey of older married couples residing in three US. metropolitan areas of Florida. A total of 94 married couples who were 60 years older participated in this study. Results indicated that aging-related physical changes, effect of physical changes on the self, self-assessed health, and evaluation of spouse's attractiveness, and perceived attractiveness (one's perception of the other spouse's appraisals of his or her attractiveness) were found to be significantly related to the body image of older men and women. For men, self-assessed health, evaluation of spouse's attractiveness, and perceived attractiveness were significantly related to body image while physical changes, effect of physical changes, and perceived attractiveness were found significant for women. The feelings of older persons about and satisfaction with their bodies and appearance were estimated by aging-related and relationship-related variables.

Purpose: The purpose of this research was to examine the effects of an exercise program on the physical, physiological, and emotional status of the aged. Method: This research adopted a nonequivalent control group pretest-posttest design. The subjects were 46 elders aged over 60 who were selected from those registered at three local health centers in G City, and 27 of them were assigned to the experimental group and 19 to the control group. The independent variable was the exercise program, and the dependent variables were physical status, physiological status, and emotional status. The exercise program was Performed for 60 minutes per time, 3 times a week and for 6 weeks. Data were collected from October to November, 2005. Result: Compared to the control group, the experimental group showed significant improvements in right lower extremity strength (F=46.119, p=.000), left lower extremity strength (F=53.265, p=.000) and waist flexibility (t=3.183, p=.003) as physical status, and in depression (t=-3.703, p=.001), perceived health status (t=4.821, p=.000), and self efficacy (t=3.866, p=.000) as emotional status. Conclusion: The results showed that the exercise program was effective in promoting the physical status, physiological status, and emotional status of the aged. Therefore, it is recommended to apply the program as a nursing intervention in clinical practice and education in communities.

Purpose: The purpose of this study was to identify the types of violence experienced by small and medium sized hospital nurses. Methods: Data were collected from March 1 to 30, 2017, using self-report questionnaires. Responses from 87 nurses were analyzed using descriptive statistics, $x^2$ test, Fisher's exact test, t-test. Results: The majority of the respondents experienced violence from patients (60.2%), visitors (25.5%), doctors (12.2%), and other staffs (2.0%). Verbal violence (80.5%) and physical threats (74.7%) were more frequent than physical violence (25.3%). Violence occurred throughout the hospital. However, verbal violence ($x^2=20.85$, p=.005) and physical threat ($x^2=20.80$, p=.006) were statistically significant according to the department. Violence occurred most frequently in surgical ward, followed by artificial kidney room, emergency room, and outpatient department. Conclusion: Most nurses are exposed to frequent violence. These results suggest that hospital should improve the respective organizational cultures and develop promotional programs and administrative policies to prevent violence. Also, hospitals should develop of violence intervention policies and education programs and counseling programs for nurses.

Objectives : According to Rowe and Kahn (1998), successful aging is the combination of a low probability of disease, high functioning, and active engagement with life. The purpose of this study was to assess the relationship between active engagement with life and functioning among the community-dwelling elderly. Methods : Data were collected from Wave 2 of the Suwon Longitudinal Aging Study (SLAS), consisting of a sample of 645 persons aged 65 and older living in the community. A social activity checklist and social support inventory were used as measures of engagement with life, along with the Physical Functioning (PF) scale as a measure of functioning. The effects of social support and social activity on physical functioning, taking into account the covariates, were analyzed by hierarchical linear regression analysis. Results : Maintenance of social activity and social support were significantly associated with higher physical function, after adjusting for sociodemographic and health-related covariates. Social support appeared to be more prominent than social activity in predicting physical functioning. Conclusions : Social support and social activity are potentially modifiable factors associated with physical function in older persons. Studies examining the role social engagement may play in preventing disability are warranted.

Purpose: This study compared the muscle activity of the lower limb according to the three types of fixed angles of the ankle joint during a lunge exercise. Methods: Twenty healthy subjects performed the lunge motion in a trial including the three types of fixed angle. The lunge motion with a neutral, 20° dorsiflexion, and 20° plantarflexion of the ankle joint were randomized and measured repeatedly. The muscle activity of the rectus femoris (RF), vastus medialis (VM), vastus lateralis (VL), biceps femoris (BF), and semitendinosus (ST) was measured by surface electromyography. Results: In the change in ankle joint angle, the RF, VL, BF, and ST muscle activity showed significant differences (p<0.05). In the 20° dorsiflexion position, the muscle activity of VL, BF, and ST showed a significant decrease compared to that in the neutral position (p<0.017). The muscle activity of RF and VL in the neutral position was greater than that in the 20° plantarflexion position (p<0.017). Only the muscle activity of the BF in the 20° plantarflexion position was significantly greater than the 20° dorsiflexion position (p<0.017). Conclusion: These results revealed a difference in the muscle activity of lower extremities in the proximal region according to the angle of the ankle joint during the lunge.
