Back-of-book-style indexes have a similar function as back-of-book indexes. The best advantage o4 back-of-book-style indexes for Information access on the web is to give direct access to specific subjects of interest. Though back-of-book-style indexes are alphabetically arranged as back-of-book indexes, they have linked index entries to contents on the site by using a anchor tag of HTML. In this research, I have created back-of-book-style indexes in two separated ways, by hand-crafted and semi-automatic Indexing. We have utilized back-of-book-style indexes, that is similar to back-of-book index of traditional information organization method of library and information science, in library circumstances.

The author conducted new back analysis method using monitoring data to a landslide which occurred around portal. In this case, because the tunnel being located under the sliding plane of the landslide, calculated value from the ordinary back analysis in which considered only stress release by the tunnel excavation didn't fit the measured value. Then, in the new method, a body force as the movement of the landslide mass was added to the ordinary back analysis and good results were obtained. Furthermore, the author carried out stability analysis of the landslide with the data of the back analysis and examined the loosened area and decreasing og the sliding plane strength due to the tunnel excavation.

Purpose: In the present study, the degree of subjective pain in chronic low back pain patients through the course of six week of yoga low back pain exercise and lumbar extensor muscle strengthening training was analyzed, and a systematic and effective home exercise therapy program was proposed. Methods: For this study, we sampled 21 random patients with chronic low back pain who were receiving outpatient treatment at G Hospital Pusan, and conducted experiment for six weeks by applying yoga low back pain exercise+modalities (7) lumbar extensor muscle endurance exercise+ modalities (7) and modalities (7). To measure the degree of pain, the visual analogue scale (VAS) and Oswestry Low Back Pain Questionnaire were used. Pain was measured before the experiment and after six weeks. Results: Significant differences were observed between yoga, extensor muscle endurance exercise and modalities (VAS=0.00 Oswestry=0.00). The yoga and extensor endurance muscle exercise reduced low back pain by more than the modalities. Conclusion: This study will be used to develop a preventive and reduction method of LBP. Therefore, Yoga and extensor muscle endurance exercise are appropriate for use as a home program exercise to reduce low back pain in patients.

The purpose of this study was to investigate the effects of swiss ball exercise and taping therapy on back muscle strength on normal college students. The aim of this study was to find effective method for back muscle strengthening. Subjects of 30 college students divided 3 groups(taping therapy group: 10, swiss ball group: 10, control group: 10). All subjects inquired physical conditions and normal exercise habits for data base. Back muscle strength measured before and after 3 weeks intervention. Taping therapy was displayed stable a growth curve in continuative a growth graph of back muscle strength better than swiss ball exercise, because it was taping therapy by periodic effect. The result of this study known to effective either taping therapy or swiss ball exercise, but both taping therapy and swiss ball exercise were effect to increase in back muscle strength.

In the back analysis of braced excavation based on displacement measurements, the accumulated errors of abnormal displacement caused by unexpected loads are usually observed. To minimize such errors, in this study, displacement increment was used fur back analysis rather than displacement for the conventional method. That is, the increment of sequential displacement is used as the objective function and the back analysis program is developed by taking advantage of sequential linear programming method by modified method of feasible directions. Based on small scale model test, the analysis of proposed method is verified.

In this paper, we propose a modified back-stepping control method in view of the dynamic model of mobile manipulator has the nonholonomic constraints, these constraints should be considered to design a tracking controller for the mobile manipulator. The conventional back-stepping controller includes the dynamics and kinematics of the mobile robot systems. and the modified adaptive back0stepping method is applied to constructing the controller. The proposed controller can realize the tracking trajectory of the reference path. The efficiency and robustness of this control method is demonstrated by the simulation.

The muscles relating to movement of painful low back was analyzed kinematically, by method of applying elastic tapes and putting non-elastic tapes on muscles involving those movements which cause pain and limitation of range of motion (ROM) in low back and trunk. Taping therapy which is effective for improvement of painful low back and which is supposed to facilitate the total and continual movement based on the postural reflexes will be presented in this paper. Fifty cases who had painful low back were investigated. Patients with painful low back were at first asked pain point and direction of painful movement, and then tested the muscles which are cause of those pain and limited motion. Before attaching tape, all subjects were divided into two groups, flexor pattern and extensor pattern, according to direction of increasing pain. Elastic tapes were applied from origin to insertion of objective muscles and non-elastic tapes were put on effective points of the muscles which were associated with respect to pain and limited ROM. As a result of this study, all subjects with low back pain significantly improved in pain and ROM at the low back. The longest treatment duration group for the low back pain cases was herniated lumbar disc(10.4 days) group. Low back pain have been treated by so many ways. muscles factor should be emphasized to be distinguish1y important to reduce low back pain. The muscles relating to make directly painful motion in low back and trunk should be confirmed by means of taping and painful motion should be analyzed by point of view of postural reflexes.

Purpose: The purpose of this study was to examine the effect of balance taping procedures on lower back pain. Method: This study is nonequivalent control group pretest-posttest design of quasi-experimental study. From May in 2004 to July in 2004, the research was done for females who have lower back pain in Gyeonggi province. Experimental group was 37, and control group was 36. The degree of lower back pain and that of the pain on activity of daily living(ADL) were each measured two times. Result: In the experimental group, the lower back pain score before taping was 6.38, that of 1 hour after the taping applied was 3.27. The lower back pain score of experimental group was significant statistically decreased and that of control group was almost not changed. Moreover, the pain score on ADL was statistically decreased in experimental group. Therefore balance taping is effective to reduce lower back pain and to improve ability of ADL. Conclusion: This study supports that balance taping may benefit individuals with lower back pain and balance taping therapy can be used as an independent nursing intervention. However, a larger study is in need to provide definite evidence and to determine long-term effects.

Purpose: The purpose of the study was to identify the pain patterns and factors affecting low back pain in middle-aged women with backache. Method: A descriptive research design was utilized. The participants were middle-aged women who visited to two back pain clinics in Wonju from October, 2006 through February, 2007. A total of 195 low back pain patients agreed to participate in this study, and data from 177 were analyzed. Data were collected using a questionnaire which included a modified short-form Korean pain rating scale, demographic factors, factors related to low back pain and health behavior. Descriptive statistics and multiple regression analysis was utilized in the analysis. Results: The mean score for low back pain was relatively low(M=21.57, SD=11.44). Among pain patterns, scores for dull pain were the highest of all the dimensions. In the regression analysis, significant factors affecting low back pain were found to be age, level of education, religion, BMI, experience of pregnancy, delivery type and exercise. These variables explained 24.8% of variance in low back pain(F=3.79, p<.001). Conclusion: These results suggest that nurses need for assessment and intervention to take into consideration pain patterns as well as factors affecting middle-age women with backache.

Purpose: The purpose of this study was to identify the effects of Koryo Hand-Acupuncture on health status(pain, trunk flexion, IADL, depression) of patients with chronic low back pain. Method: This study used a quasi experimental pre-test and post-test design. Data were collected from December 1st, 2000 to December 20th, 2001. 63 chronic low back pain patients(35 experimental group, 28 control group) admitted to the Back-School and consented to this study. The experimental group participated in treatment: Koryo Hand-Acupuncture and AB-Bong. Two groups was homogeneity. After 4 weeks the effects of treatment on the health status was measured between experimental and control group. Data were analyzed using SPSSWIN 10.0 with crosstab, t-test, and paired t-test. Result: In the experimental group, pain(t=4.85, p=.000) and IADL difficulty(t=2.05, p=.045) was significantly lower than those in the control group. It makes no difference trunk flexion(t=-1.60, p=.114) and depression(t=1.50, p=.138) between experimental and control group. Conclusion: These findings indicate that Koryo-Hand Acupuncture is an effective method for reducing pain and IADL difficulty in patients with chronic low back pain, and is considered as a independent nursing intervention for chronic low back pain.
