  • With the increasing use of tower cranes higher than free standing height, the importance of lateral support is also growing. Since the fall of 43 tower cranes hit by the last typhoon 'Mami' in 2003, regulations and concerns about safety of construction equipment have increased and construction laws regarding lateral support have been strengthened. In Korea, where there are many large-scale apartment housing construction works with the development of new towns, Rope Guying is a more economical construction method than Wall Brace which fixes building structure like building wall and slab. The safety of this Rope Guying is not verified and many construction works are still carried out based on the experience of site managers. There has been no case of construction work where frame and measurements are applied. The objective of this study is to examine the safety of Rope Guying method and ensure the effective implementation of equipment and prevention of disasters.

  • The purpose of this study was to compare the electromyographic(EMG) activities of trunk and hip muscles between right and left sides while subjects performed prolonged manual task in asymmetric and symmetric weight-bearing posture. Fifteen healthy male college students were recruited for this study. The subjects were asked to perform bimanual upper extremity task for 6 minutes in two different standing postures. In the symmetric weight-bearing posture, the subjects were standing with evenly distributed body weights to both legs. In the asymmetric weight-bearing posture, the subjects distributed about 90% of their body weight onto their preferred(supporting) leg and 10% of their body weight onto the opposite leg while they were standing. EMG activities of the right and left internal oblique, erector spinae, gluteus maximus, and gluteus medius were measured and normalized as % MVIC. Then the EMG data were statistically analyzed using paired t-tests. The EMG activities of all measured muscles were not significantly different between the right and left side in the symmetrical weight-bearing posture(p>0.05). However, the EMG of the supporting side internal oblique was significantly lower than the opposite side(p<0.05), and the EMG of the erector spinae, gluteus maximus, and gluteus medius were significantly greater on the supporting side(p<0.05). The results of this study support that unbalanced use of right and left muscle possibly causes the changes in muscle length which results in asymmetry of trunk and hip muscles. Furthermore, the uneven weight support onto right and left legs will cause a distortion of viscoelastic ligaments around hip and sacroiliac joints in the long run. Further studies to determine the effect of various manual tasks on the trunk and hip muscles as well as the effect of asymmetrical weight-bearing standing posture on hip and back muscle fatigue may be required.

  • The purpose of this study was to examine the reliability and validity of the observed behaviors of subjects who suffered from low back pain with spinal diseases, Thirty two low back pain patients admitted on the neurosurgical unit in an army hospital were compared with 30 normal controls belonged to an army unit, by means of matching the age, hight and weight. Observed pain behaviors were developed by the researcher on the bases of literature and patient observation. This tool consists of 18 behaviors seperated into two major groups : mutually exclusive and concomittent behaviors. The mutually exclusive behaviors included coding cathegories for 6. body motions assumed by the subjects during the observation session. These 6 standardized motions consisted of sitting from standing first, and serially tying down, reclining, sitting again, and then standing, 6 steps walking. Concomittent behaviors consisted of 12 observable patterns that can be observed systematically from the face, grimacing, bracing, rubbing, walking with arms fixed, support with hands on sitting or standing, guarded movement, limping, unbalaced weightbearing, stopped movement from tying position to sitting, sighing and graoning. Subjects were videotrecorded as they performed a 6-standardized sequence of motions, simultanously researcher measured the time spent performing each motion and step length. Patients were asked torate their subjective pain score on the 10 mm graphic rating scale ranging from 'no pain' to 'sever pain'. For scoring of the pain behaviors, two trained nursing officiers independently and simutanously viewwd each videorecording and checked subject 'pain behaviors at the observational item checklist. The result of the study are summarized as follows : 1. Reability of the observational tool was a=.845. 2. Spearman's rho and percentage agreement were p=.97 and 81.7 persent respectively, that indicate adequate interrater reability of this tool. 3. The sensitivity rate of the tool was .875 while specificity rate .866 for differentiating patient from the normal. 4. When difference in the objective pain indices between patient group and control were compared, there was significant difference of all indices, such as pain behavior(t=7.71, p=.0001). spent time performing motion(t=14.2, p=.0001), step length (t=-10.72, p=.0001). 5. There were differences in the objective indices the subjective pain subgroups (low, medium, high). Differences in the mean score of objective pain behavior (F=6.376. p=.005) and spent time for moyion(F=4.631, p=.018). But there were no significant differences in the step length among the subgroups(F=.667, p=.521). 6. Highly correlated pain behavior items wiyh subjective pain score were 'stopped movement from lying position to sitting', 'limping', 'support with hands on sitting or standing', 'bracing', 'guarding' and 'walking with arms fixed'. In summary, although some of rho behavior items such as sighing and groaning in this study could not be observed because of videotaped datd, the reliability and validity of the over all observation method were satifactory. Thus, the results of the present study demonstrate rye potetional utility of the tool in assessing objective pain complementing self-reported pain in low back pain patients.

  • The purpose of this study is to figure out problems and to suggest improvement scheme by examining 31 of the disabled who used power wheelchair developed for safe moving and standing support. The results are as follows. First, standing power wheelchair that enables the disabled to sit and stand up was developed. It can also be used as means of transportation for moving in narrow space and in a short distance. In the usability test of this prototype, two groups were respectively examined in 60 evaluation items. One group consisted of 16 people with disabilities using manual wheelchairs. And the other one consisted of 15 people with disabilities using automatic wheelchairs. The entire average figure of two groups was shown to be 2.72 and standard deviation was 0.820. Specifically, the average figure of the group in manual wheelchair was 2.85 and the one of the other group in automatic wheelchair was 2.57. And both group replied that the move to stand up and sit on both types of wheelchair was the most inconvenient thing. It shows why ergonomic design for persons with under extremity disabilities to stand up and sit is needed. Second, with further study based on the results of usability test of the disabled, it will make contribution to increase the quality of people with disabilities by helping them move and do daily lives on their own.

  • Purpose: The main purpose of this study was to explore the adaptation experience of adolescent cancer survivors during and after cancer treatment, and their perceived social support networks. Methods: This study was a qualitative descriptive study using the in-depth interview. Eight adolescent cancer survivors who were diagnosed with cancer between 11 to 18 years old participated in the study. Results: The adaptation experiences of adolescent cancer survivors over time were identified within five categories for during their treatment such as "being catapulted from one's life," "standing at the center of discomfort," "falling behind the line," "accepting the change," "being developed", and another five categories for after the treatment including "being shackled," "encountering the forgotten reality," "overcoming and emerging from the reality," "growing into adulthood," "entering into a new orbit." Participants reported the various members of their social support network and their roles during and after the treatment as well. Conclusion: While adolescent cancer survivors adjusted to their changing situations after the cancer diagnosis, their internalized adaptation, as well as perceived social support from their diverse surrounding network, played significant roles. These findings will become a valuable asset for developing age-appropriate nursing interventions to promote psychosocial adjustment of adolescents with cancer.

  • The cryogenic vessel, storing a liquified solutions as LOX and $LN_2$, consists of a external vessel, internal vessel, thermal insulator and internal support. The internal support should be satisfied with mechanical strength not only to support weight of internal tank but also to maintain uniform space between external and internal tank in spite of external mechanical shock. However, excessive structure design of internal supports is able to increase the amount of heat conduction and the rate of vaporization. The thermal insulator, filled with space between a external and internal vessel, reduces the rate of heat transfer and guarantees the standing time of cryogenic vessel. Especially powder type of insulator has low thermal conductivity and reduce the specification of structure design. In order to evaluate the effect of insulator on structure design, the experiment set-up simulated cryogenic vessel was tested in shock environment according to thermal insulator. As a result, the behavior of internal support under external shock was understood and the design criteria was able to be suggested.

  • The purpose of this study was to investigate how wearing calf support and applying of electronic muscle simulation(EMS) affected the ability to balance. In this study, the one leg standing test for static balance and the Y balance test for dynamic balance were used to assess balance. At this time, the pressure of the calf support was different to produce two supporters, and a difference between wearing the support before, after, and after applying EMS was evaluated. Seven men in their 20s with healthy bodies were measured five times each with a five-minute break, taking into account muscle fatigue, and the difference between each variable was analyzed through a follow-up test using nonparametric statistical analysis. Studies have shown more difference from supporter B with a more appropriate pressure (mmgh) for increasing balance capability than from supporter A. In addition, it was confirmed that the use of EMS electrostimulation and support before measuring the balance capability resulted in a greater difference. The proper pressure (mmgh) supporters and EMS can increase the ability to balance, and these results can be expected to improve the balance ability of ordinary people in their daily lives.
