Background: Stroke patients require arm movement exercising for various stimulations in standing position for various stimulations rather than in a sitting position because they require integrated skillful movements, such as stretching, holding, and controlling. Objective: This study was conducted to provide foundational clinical data about lower limb global synkinesis in stroke patients using arm movements in a standing position. Design: Randomized controlled trial. Methods: The subjects were divided into a control group (n = 10) and an experimental group (n = 10), and a pre-test was conducted to evaluate leg global synkinesis (GS) and balance. Intervention method is stretching an arm to hold a ball, repeating supination and pronation of the hand only while maintaining the arm extended as much as possible, repeating shoulder abduction and adduction while holding the pegboard. This was followed by a three-week intervention during which re-measurement was conducted in the same way as was done for the pre-test. Results: The control group showed a significant difference in GS and balance during plantar flexion (p<.05), and the experimental group showed a significant difference in GS and balance during all movements (p<.05, p<.01, respectively). There was a significant difference in GS and balance between the two groups during dorsiflexion (p<.05, p<.01, respectively). Conclusion: The findings demonstrate that human arm movements in a standing position can reduce GS in the affected limb, and balance can be improved by stimulating the surrounding tissues of the affected limb and changing them positively.

PURPOSE: The aim of this study was to investigate the influence of hip abduction velocity and position change on the relative onset times of the gluteus medius, the tensor fascia latae, and the quadratus lumborum in healthy subjects. METHODS: For this study, 15 healthy young adults were recruited. The subjects were asked to move their hip joints up to 35 degrees of abduction at a speed of $70^{\circ}/sec$ and $17.5^{\circ}/sec$ in the supine and side-lying positions. Electromyography data was collected for the gluteus medius, tensor fascia latae, and quadratus lumborum to determine the onset times. RESULTS: There were significant differences between the fast speed ($70^{\circ}/sec$) and the slow speed ($17.5^{\circ}/sec$) in hip abduction in a supine position and in a side-lying position, relatively. The onset time of the gluteus medius was faster than that of the tensor fascia latae and the quadratus lumborum in the side-lying position at the speed of $70^{\circ}/sec$ and $17.5^{\circ}/sec$. CONCLUSION: The findings of this study indicated that hip abduction in a side-lying position is an effective method to recruit the gluteus medius earlier than the tensor fascia latae and the quadratus lumborum. Thus, the exercise position is considered necessory in the purpose of rehabilitation for gluteus medius muscle strengthening program.

Background: Conventional spinal saddle block is performed with the patient in a sitting position, keeping the patient sitting for between 3 to 10 min after injection of a drug. This amount of time, however, is long enough to cause prolonged postoperative urinary retention. The trend in this block is to lower the dose of local anesthetics, providing a selective segmental block; however, an optimal dose and method are needed for adequate anesthesia in variable situations. Therefore, in this study, we evaluated the question of whether only 1 min of sitting after drug injection would be sufficient and safe for minor anorectal surgery. Methods: Two hundred and sixteen patients undergoing minor anorectal surgery under spinal anesthesia remained sitting for 1 min after completion of subarachnoid administration of 1 ml of a 0.5% hyperbaric bupivacaine solution (5 mg). They were then placed in the jack-knife position. After surgery, analgesia levels were assessed using loss of cold sensation in the supine position. The next day, urination and 11-point numeric rating scale (NRS) for postoperative pain were assessed. Results: None of the patients required additional analgesics during surgical manipulation. Postoperative sensory levels were T10 [T8-T12] in patients, and no significant differences were observed between sex (P = 0.857), height (P = 0.065), obesity (P = 0.873), or age (P = 0.138). Urinary retention developed in only 7 patients (3.2%). In this group, NRS was $5.0{\pm}2.4$ (P = 0.014). Conclusions: The one-minute sitting position for spinal saddle block before the jack-knife position is a safe method for use with minor anorectal surgery and can reduce development of postoperative urinary retention.

This study was conducted to determine the smoke component concentration and the smoke distribution in the cambridge filter pad and cigarette filter with stalk position and grade of Korean leaf tobaccos. 12 grades of flue-cured and burley leaf tobaccos which were taken from the Kim-cheon and Ock-cheon leaf tobacco processing factory were used for this study. Six kinds of smoke components such as tar, nicotine, water, carbon monoxide(CO), carbon dioxide($CO_2$) puff No. collected in the cambridge filter pad and cigarette filter were analyzed. Also, nicotine/tar, CO/tar ratio were calculated from the analytical data. Puff no., CO, and $CO_2$ concentration of flue-cured and burley tobacco leaves at high stalk position were higher than those of low stalk position, and these components were increased in high grade of leaf tobacco. Compared with flue-cured tobacco, burley tobacco showed a little values of puff no., nicotine, and tar concentration. The pH range of burley tobaccos was broader than that of flue-cured tobaccos, and the ammonia concentration of burley tobaccos was significantly higher than that of flue-cured tobaccos. The pH value and ammonia concentration of burley tobaccos were decreased as stalk position of leaf tobaccos decreased. The distribution of smoke components collected in the cambridge filter pad and cigarette filter was different with a different grade and stalk position of tobacco leaves. In high stalk position of tobacco leaves, the portion of smoke components collected in the cambridge filter pad was also increased. The average nicotine, water, and tar removal efficiency by a cigarette filter in a flue-cured tobacco were 37%, 64%, and 48%, respectively. Compared with flue-cured tobaccos, smoke components of burley tobaccos had high nicotine and low water removal efficiency by a cigarette filter. The average ratio of nicotine/tar and CO/tar of flue-cured tobaccos and burley tobaccos were 0.097, 1.22, 0.094, and 0.97, in order. Nicotine/tar ratio was decreased and CO/tar ratio was increased in low stalk position.

This study is to observe the effects of nursing care according to change of position for comfort during labor and safe delivery of newborn infants and perturbment women. Fifty antepartal primipara with labor pain who were admitted to the delivery room of H University Medical Center from September 1, 1976 to November 15, 1976 (Estimate Delivery Confinement) were selected for this investigation. Among the 50 parturiencys, the experimental group (28 primipara) were placed in 30 degree upright sitting position and the control group (22 primipara) were placed in the supine position. following placement, both groups were observed. The summarized findings of the study were as follows; 1. There was a noticeably significant difference in the duration of the first stage of labor (defined as 4 cm. dilatation of the cervical os with the fetal presenting part engaged to full or 10 cm. dilatation) , between the two groups. For women in the 30 degree upright sitting position, the first stage of labor was close to 33.66 minutes shorter. than for the women in the supine position. (t : 32.79, D.F : 48, p<0.0,i) 2. Although slight differences were observed between the Apgar Scores of the newborn infants of primipara in the two groups, these were not significant. The mean Apgar Score among the newborn infants of primipara in the 30 degree upright sitting position was 9.64 compared with 9.04 for the newborn infants of primipara in the supine position, a difference of 0.6. (x$^2$= 2.44, D.F : 2, p〉0.05) 3. There was a significant difference in the conformability of the perturbment women between the two groups because the shortened duration of the first stage and the high level of comfort score calculated for six factors (body activity, serving bed pan, serving kidney basin, pushing, deep breathing and perturbment women's feelings), that affect nursing care.

Purpose: The purpose of this study was to evaluate the relationship between the position of mesiodens and its complications. Materials and Methods: The subjects for this study consisted of 172 patients with mesiodens. Panoramic radiographs and cross-sectional tomography were taken of all of the subjects. Their clinical records and radiographs were analyzed in order to study the direction and vertical and sagittal position of mesiodens, as well as complications caused by mesiodens. Results: The number of mesiodens was one in 112 cases (65.1%) and two in 60 cases (34.9%). Complications were found in 121 mesiodentes (52.2%), with being median diastema the most frequent. The incidence of complications was high in erupted mesiodens (75.0%), in horizontal mesiodens (89.8%) and in mesiodens located within the arch (75.7%), but was low in mesiodens impacted above apex (29.8%), in normal position (34.4%) and in palatally positioned mesiodens (46.5%). Conclusion: It was suggested that the frequency of complications was different according to the vertical position, the direction of the crown and the sagittal position.

Purpose : There is no validated method for measuring the toe flexor strength that can isolate the intrinsic muscles of the foot from the extrinsic muscles. This study compared the hallux flexion force (HFF) and muscle activity in the foot and ankle according to ankle position [plantarflexion (PF), neutral, and dorsiflexion (DF)]. Method : The study enrolled 17 subjects. In the sitting position, the HFF and activities of the abductor hallucis (AbdH), tibialis anterior (TA), and gastrocnemius (GCM) muscles were measured using a digital dynamometer and a wireless electromyography system, respectively. Subjects were instructed to flex the great toe maximally in three different ankle positions. Three 5-second trials were performed to measure the HFF and muscle activities in each condition. Repeated-measures ANOVA was used to compare the variables and paired t-tests with the Bonferroni correction were used for post-hoc pair-wise comparisons. The significance level was set at .016. Result : The HFF in DF was significantly greater than in any other ankle position (p<.01). The TA activity was greatest in ankle DF and that of the GCM was greatest in PF (both p<.01). However, there was no significant difference in AbdH activity according to ankle position. Conclusion : These results suggest that selective strength measurement of the foot intrinsic muscles in HFF should be performed with the ankle in the neutral position.

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.

The purpose of this study is to identify whether ethical values of korean nurses are deontological or utilitarian. Nurse's ethical value questionnaire was developed from review of literature and interview of nurses in the clinical settings. Content validity was tested from three nursing faculties and staffs. Ethical problems are categorized into four areas : 1) human life area 2) nurse-patient relationship area 3) nurse - nursing task relationship area 4) nurse-collegue relationship area The data were obtained from the 404 nurses in the clinical settings from Feb. to Mar. in 1990 by ethical value questionnaire. The analysis of data was done by Pearson's correlation coefficient, t-test, anova. The results of this study were as follows : 1. The ethical values of human life slightly took up the position of utilitarian. 2. The ethical values of nurse - patient relationships slightly took up deontological position. 3. The ethical values of nurse - nursing task relationships slightly took up deontological position. 4. The ethical values of nurse - colleague relationships greatly took up deontological position. 5. The ethics of nurses related to demographic characteristics of religion, attitude of nursing, ethical standards, education level and post. Those who have religion took up more deontological position than those who have not. Those who have positive attitude of nursing and firm ethical standards took up more deontological position than those who have not. Those who have higher education level and post took up more deontological position than those who have not.

The purpose of this study is to identify the leadership and subordination of hospital nurses: to determine the leadership and subordination by nurses' characteristics, which are age, educational background, career, and position of nurses. 279 staff nurses, 13 charge nurses, 32 head nurses and 16 nurse supervisors were participated in this study during the period from Dec. 5 to Dec. 20, 1986. Subjects were instructed to rate at one of five points likert type scale on the 26 items of leadership and subordination. The reliability of the items (Cronbach's α) were 0.63∼0.84. Among the total 26 items, 8 items on authority, 4 items on human relation, 9 items on committment of position and 5items on committment of job were summed to cummulative scores in each category. As a result of data analysis nurses who perceive positive on authority are 68.6% and positive on human relation are 67.9%. The perception of authority is different by age, Career and position of nurses. (P<0.05). And nurses who perceive positive on committment of position are 84.7% and positive on committment of job are 62.1%. The perception of committment for position is different by age, career and position of nurses (P <0.05), and committment of job is different by age and position. (P<0.05).
