Objective: This study was conducted to provide basic data on physical function improvement activities of elderly care facilities by identifying the degree of physical improvement activities of elderly caregivers. Design: Descriptive correlational study. Methods: The instrument of this study consisted of 12 questions on the general characteristics of the subject. For the assessment of improvement in physical function activities, the measuring tool used for the elderly consisted of a total of 20 questions. For data analysis, Pearson's correlation coefficient & Spearman's rho and multiple regression were used. Results: The higher the age of the subjects, the lower their educational background (r=-0.273, p<0.05), and the higher the probability of having a religion (r=-0.258, p<0.05), the more stable the employment type (r=-0.333, p<0.05). The higher the level of education, the higher the monthly income (r=0.187, p<0.01), and the shorter the career (r=-0.204, p<0.05). The more stable employment, the more unstable duty (r=-0.245, p<0.05), and the more unstable work, the higher the monthly income (r=-0.206, p<0.05) and the longer the career, the higher the monthly income (r=0.247, p<0.05). The more stable the employment, the more activities to improve physical function were found (r=0.341, p<0.05), and the more unstable the duty, the more activities to improve physical function were found (r=0.321, p<0.05), and the higher monthly income, the less physical function improvement activities (r=-0.196, p<0.05). Conclusions: It is necessary to provide regular services by a dedicated physical therapist for physical function improvement activities in order to improve the quality of life of the elderly in the future.
Objective: The aim of this study was to investigate 1) the difference in static lower extremity alignment (SLEA) according to a history of lateral ankle sprain (LAS), 2) to identify SLEA factors affecting LAS, and 3) to present the cut-off value and 4) the usefulness and limitations of the SLEA measurement. Method: This case-control study recruited 88 men (age: 27.78±4.69 yrs) and 39 women (age: 24.62±4.20 yrs) subjects with and without LAS. SLEA measurement protocol included Q angle, tibiofemoral angle, genu recurvatum, rear foot (RF) angle, tibal varum and torsion, navicular drop, ankle dorsiflexion range of motion (DF ROM). Independent t-test, logistic regression and receiver operating characteristic (ROC) curve were used for statistical analysis. Results: Men with a history of LAS had significantly smaller Q angles both in standing and in supine position, while women with a history of LAS had significantly greater DF ROM in non-weight bearing (NWB; p < 0.05). Logistic regression model suggests tibial varum (OR = 0.779, p = 0.021) and WB DF ROM (OR = 1.067, p = 0.045) were associated with LAS in men. In case of women, there were no significant SLEA factors for LAS, however, ROC curve analysis revealed standing RF angle (AUC = 0.647, p = 0.028) and NWB DF ROM (AUC = 0.648, p = 0.026) could be affecting factors for LAS. Conclusion: There are differences in SLEA according to the history of LAS, furthermore, the identified items were different by sex. In case of men, tibial varum and WB DF ROM affect LAS occurrence. Standing RF angle and NWB DF ROM of women could be a predictor for LAS. However, since the sensitivity and specificity in most of the SLEA measurements are low, kinematic in dynamic tasks should be considered together for a more accurate evaluation of LAS risk.

Because the education system that based on objective data is needed for the beginning technologists in the department of medicine laboratory, development of the CAI system based on Gram-Stain images is needed in clinical microbiology field. So, in this study, we implemented CAI system based on Gram-Stain images for medical technologists under Web using multimedia toolbook. Because this system is implemented under Web, more and more beginning technologists can have a remote-education beyond time and space, can save human power and time that needed due to hold in common of educational information, and cannot learn mistaken microbiology images because of learning execution based on objective data. Also, implemented system brings a higher interest and a learning effect to medical technologies because of hyper-media method that offered from toolbook. In the future, it will be needed a continuous acceptance of changing knowledge and it will be useful system for technologist in case of applying various examinations based Gram-Stain method of this study.
The main objective of this study is to evaluate role-related job stressors of physical therapists and to examine the relationship between job stress and organizational effectiveness. A survey was conducted through structured questionnaire for the physical therapists working in Busan area, and data from 175 therapists were utilized in the final analysis. Survey items included general characteristics of the therapists(sex, age, education, marital status, religion, income, etc.), various kinds of job stressors(role conflict, role overload, role ambiguity, physical burden), and organizational effectiveness measured in terms of job satisfaction, organizational commitment and organizational citizenship behavior. Major results are as follows: 1) The level of physical therapists' job stress was found to be in average range, recording 2.65 on 4-point scale. 2) It appeared that main job stressors of physical therapists were role ambiguity and role overload, and this was more apparent in the case of younger, relatively less-educated, unmarried, and lower-grade employees. 3) On the other hand, in the case of relatively more-educated and higher-paid employees, role conflict was comparatively more important job stressor. 4) Regression analysis suggested that, as Job stress increased, job satisfaction and organizational commitment decreased; however, no significant relationship was found between job stress and organizational citizenship behavior. 5) These results imply that, in order to perform effective and efficient personnel administration of physical therapists, adequate job stress management would be very important task for the hospital managers.
Objective: The study analyzed the awareness of physical therapists regarding correct breathing methods and the effect of breathing training on patients. Design: A cross-sectional survey study. Methods: Physical therapists who agreed to participate in the study, held a license as a physical therapist, and had training or experience in breathing were included as subjects. A total of 136 questionnaires were collected, out of which 129 were analyzed. The questionnaire consisted of 26 items, divided into several sections covering awareness of breathing methods, breathing and muscles, breathing and mind, breathing and movement, perception of mouth breathing and nose breathing, experience applying respiration as a treatment, perception of breathing and treatment, awareness of breathing and pain, awareness of breathing and chronic diseases and prevention, perceptions related to breathing and sleep, and educational background. Results: The study found that most therapists were aware of diaphragmatic breathing, but not Lamaze breathing. 76.7% claimed to that there is a correct breathing method, and the majority were aware of the reasons for correct breathing. The majority believed in the therapeutic effect of breathing, with core exercise breathing training being the most commonly used in therapy. 81.7% of therapists had taught a specific breathing method to a patient, and diaphragmatic breathing was the most provided treatment. There was no significant difference in perception according to clinical experience, but there was a significant difference in perception according to educational background. Conclusions: The study provided clinical background on Physical Therapists' belief on correct breathing method, and uses of breathing training during treatment. The results suggest there is a need for a coherent education on breathing method and techniques among Physical Therapists.

Objectives: The aim of this study was to investigate the correlation between the obesity rate in elementary school students in Daejeon and the relevant factors such as social-demographical factors, genetic factors, birth factors, diet factors and intelligence factors. Methods: For the research, 443 fourth grade students, 405 fifth grade students and 417 sixth grade students from six elementary schools in Daejeon Metropolitan City Participated in this study and classified into three groups: normal-weight group, mild obesity group, and moderate or severe obesity group. Results: The total obesity rate of the elementary school students in the school district of Daejeon Metropolitan City was 14.2%; the rate of mild obesity was 7.2%; the rate of moderate obesity was 5.5%; and the rate of severe obesity was 1.5%. The obesity rate of surveyed boys was 16.9%, and the obesity rate of girls was 11.1%. The significant factors for girls' obesity were fathers' EMI, mothers' EMI, living standards, constant demand of foods, preference for greasy foods, frequency of eating snacks, and daily walking hours. It was found that students' subjective mind and objective health index were related to obesity. In the case of obese students, they had more concern about their health and more stress from the dissatisfaction of their physical appearance than normal students. Conclusions: From the above evidences, it is apparent that the obesity of elementary school students has strong relations with eating habits rather than physical activities. It is to be hoped that obesity prevention programs such as effective meal guidance. parental guidance for watching TV, and intense physical activities will be included in the curriculums of health education for elementary school students.

BACKGROUND/OBJECTIVES: Although some juices affect subjective sleep quality, there is a lack of information on the effect of a specific juice on objective sleep quality and heart rate variability (HRV) during sleep; thus the present study investigated whether a blended juice made from natural extracts influenced sleep quality and HRV during sleep in adults with disturbed sleep. SUBJECTS/METHODS: A randomized, crossover study was conducted on twenty-five adults (15/10, female/male) complaining of difficulty initiating or maintaining nighttime sleep (Pittsburgh sleep quality index [PSQI] ≥ 5). During feeding sessions (FS), subjects received sleep-inducing juice made of natural ingredients (250 mL/trial) twice a day for 8 weeks or non-FS (N-FS) for 8 weeks while maintaining normal activities. Sleep quality and parameters were recorded via wearable actigraph for 7 consecutive days, and PSQI scores were assessed before and after the intervention. HRV was also monitored at rest and during sleep. RESULTS: After receiving the sleep-inducing juice intervention (FS), PSQI scores were significantly decreased (P < 0.001) and correlated with a significant decline in fatigue severity scale and visual analogue scale levels (P < 0.05; both). HRV indices of vagal activity were significantly improved during FS (P < 0.05), and no significant differences in N-FS were observed. Sleep efficiency and total sleep time increased significantly (P < 0.05) and sleep latency, total counts, sleep fragmentation index, and movement index, decreased significantly (P < 0.05, all 4) during FS, with no significant differences-observed during N-FS. CONCLUSIONS: This study results demonstrated that an 8-week course of sleep-inducing juice has led to improve sleep quality, suggesting an enhanced cardiac vagal tone during sleep. Thus, it could be a well-tolerated option for adults with disturbed sleep.
Objective : The purpose of this study was to find some kinetic variable's relationships between personal records and low records in female high jump. Methods : Collected data of the subjects(N=8, ages: $25.5{\pm}1.85$, height: $173{\pm}5.83$, mass: $54.75{\pm}6.36$ personal record: $1.71{\pm}0.04$, low record: $1.62{\pm}0.03$) were used for the last three strides and take-off phase. Five video cameras set in 30frames/s were used for recording. After digitizing motion, the Direct Linear Transformation(DLT) technique was employed to obtain 3-D position coordinates. The kinematic and kinetic factors of distance, velocity, angle, impulse, jerk variables were calculated. A paired t-test was applied for the difference of variables between personal records and lower records and for correlation with performances and variables. The significance level was accepted at p<.05. Results : There was no relationship between pattern of stride and performance. However, rate of change of velocity was related with cental of mass height(CMH) at peak point(PP). Knee, hip, backward lean, foot plant, approach and take off angle showed no difference between best record and low record. Vertical impulse momentum also showed no difference between performances. Conclusion : According to a t-test result, there were significant differences in CMH at PP and jerk at touch down between best record and low record.
Objective : This study aimed to understand how increased heart rates at the time of drop landing during a step test would affect biomechanical variables of the lower extremity limbs. Background : Ballet performers do more than 200 landings in a daily training. This training raises the heart rate and the fatigability of the lower extremity limbs. Ballet performance high heart rate can trigger lower extremity limb injury. Method : We instructed eight female ballet dancers with no instability in their ankle joints(mean ${\pm}$ SD: age, $20.7{\pm}0.7yr$; body mass index, $19.5{\pm}1.2kg/m^2$, career duration, $8.7{\pm}2.0yr$) to perform the drop landing under the following conditions: rest, 60% heart rate reserve (HRR) and 80% HRR. Results : First, the study confirmed that the increased heart rates of the female ballet dancers did not affect the working ranges of the knee joints during drop landing but only increased angular speeds, which was considered a negative shock-absorption strategy. Second, 80% HRR, which was increased through the step tests, led to severe fatigue among the female ballet dancers, which made them unable to perform a lower extremity limb-neutral position. Hence, their drop landing was unstable, with increased introversion and extroversion moments. Third, we observed that the increasing 80% HRR failed to help the dancers effectively control ground reaction forces but improved the muscular activities of the rectus femoris and vastus medialis oblique muscles. Fourth, the increasing heart rates were positively related to the muscular activities of the vastus medialis oblique and rectus femoris muscles, and the extroversion and introversion moments. Conclusion/Application : Our results prove that increased HRR during a step test negatively affects the biomechanical variables of the lower extremity limbs at the time of drop landing.
Objectives: The objective of this study is to investigate the relation between the obesity prevalence of elementary school students and some factors such as socio-demographic factors, parent's obesity, diet habit and physical activity. Methods: The students of the fourth(443), fifth(405) and sixth grade(417) at six elementary schools in the school district of Daejeon metropolitan city were sample-surveyed and classified into a normal group, a non-intensive obesity group, and a highly intensive obesity group. Results: 1. The obesity rate of the elementary school students in the school district of Daejeon metropolitan city was total 14.2%. 2. The obesity rate of students with parents who had high BMI was notably higher than the other groups. 3. Diet factors such as eating fast, always eating one more, liking fatty food and the frequency of snacks were more critical than physical activity factors in relation to school children's obesity. Conclusions: From the above evidences, it is apparent that the obesity of elementary school students have strong relations with eating habits. It is needed that obesity prevention program such as effective meal guidance in addition to intense physical activities is included in the curriculums of health education for elementary school students.
