Purpose: The study was to examine the effect of lumbar stabilization exercise on back pain, physical fitness, sleep, and depression in middle-aged women who have chronic back pain. Methods: With one group pre-post test design, 18 subjects who have had more than 6 months of back pain were recruited by convenience sampling in D metropolitan area. Lumbar stabilization exercise was based on Tai Chi for back pain program developed by Lam(2003). This program was mainly focusing on strengthening lumbar stabilizing muscle for one hour per session, twice a week for 20 weeks. Degree of back pain, back pain disability, sleep, and depression were measured at three time points(pretest, 12 weeks, and 20 weeks) by a structured study questionnaire. Physical fitness variables including waist flexibility, mobility, and back muscle strength were measured three times at health promotion center located in the university hospital. Data were analyzed by frequency, descriptive statistics, and repeated measures of ANOVA. Results: Mean age of subjects was 52 years(SD = 6.4). Most of them(90%) had suffered from back pain more than one year and 67% was taking medicine to relieve their back pain. Results showed that back pain score and disability score were not significantly decreased after the exercise. On physical fitness variables, however, waist flexibility(F = 3.50, p = .04) and mobility(F = 3.31, p = .04) were improved after the exercise. Quality of sleep(F = 4.48, p = .03) was improved gradually and depression scores were also decreased(F = 3.12, p = .05) after the exercise. Conclusion: This lumbar stabilization exercise was not able to reduce chronic back pain, but could improve physical fitness and psycho-social variables for community dwelling women who have chronic back pain. Further study is needed to replicate this exercise with control group to confirm the positive effect.

Objectives : Taichi for arthritis was developed in 1997 by Paul Lam, M.D. of family medicine in Australia. It is an exercise treatment program and a good approaching method of the oriental medicine for arthritis. However, clinical and academical researches were rare. The purpose of this study is to investigate the effectiveness of the Taichi for arthritis. Methods : We used the medical literature search system, MEDLIS and the database of academic journal, DBpia to search medical studies published in korea. Keywords were "Taichi", "Tai Chi Chuan" and "Arthritis". We classified literatures with two criteria, year of publishment and study design. Then we classified as placebo design and summarized whole material. We determined its effectiveness by positive-negative results of Taichi for arthritis. Results : Taichi for arthritis could release pain of the rheumatoid or degenerative arthritis. Also it is thought to increase muscular power and enhance physical flexibility, balance. Conclusions : There were limits to ensure effectiveness because of small number of studies comparing Taichi with other exercise program for arthritis. However the Taichi for arthritis could have positive effect to treat the rheumatoid and degenerative arthritis. We hope further studies to be followed in oriental medical field.

Purpose: The purpose of this study was to assess the effects of virtual reality-based continuous slow exercise on muscle strength and dynamic balance capacity, in older adults over 65 years of age. Methods: Twenty-six volunteers were randomly divided into two groups; a Virtual Reality (VR) exercise-group ($67.8{\pm}4.1$ yrs) and a Control group ($65.5{\pm}5.2$ yrs). The VR group participated in eight weeks of virtual reality exercise, utilizing modified Tai-Chi provided by a motion capture system, and the Control group had no intervention. The hip muscle strength and dynamic balance of the members of both the VR group and the Control group were measured at pre- and post-intervention, using a multimodal dynamometer, and backward stepping test, respectively. Results: 1. After the 8-week VR-based exercise, the VR group showed significant improvement of hip strength, compared to the control group: hip extension (p=0.00), flexion (p=0.00), abduction (p=0.00), and adduction (p=0.00). 2. After the 8-week VR-based exercise, the VR group showed significant improvement of dynamic balance capacity as ground reaction force, compared to the control group. Eyes opened backward stepping test: Fx (+) (p=0.00), Fy (-) (p=0.02), Ver (+) (p=0.02) direction. Eyes closed backward stepping test: Fx (+) (p=0.04), Fy (-) (p=0.04), Ver (+) (p=0.03) direction. Conclusion: The VR group showed improvement of their hip muscle strength, and dynamic balance capacity. Therefore VR-based continuous slow exercise would contribute to reducing the risk of falls in the elderly.

Zirconia nanoparticles were synthesized by hydrothermal process, and experimental parameters such as reaction temperature, reaction time, kind and concentration of precipitator, kind of precursor were varied. Particle sizes and crystalline phases of each synthesized nanoparticles were analyzed with X-ray diffraction and FE-scanning electron microscope (SEM). The particle size and crystallization of zirconia increased with increasing concentration of precipitator. The growth rate of particle sizes when NaOH as a precipitator was used also increased more than that of KOH. Therefore, the use of KOH rather than NaOH was more effective in the control of particle sizes. An amorphous zirconia nanoparticle was found in 4 h of hydrothermal reaction, but the monoclinic zirconia nanoparticle was found in 8 h and over of hydrothermal reaction, and the width of nanoparticles was slightly slimmed and the length of nanoparticles was slightly extended with increasing reaction time. The smallest particle size was produced at the same synthesis condition when zirconium chloride among the precursors such as zirconium (IV) acetate, zirconium nitrate and zirconium chloride was used.

In spite of excellent thermomechanical performance the majority of aromatic polyimides are so poor in processability due to their high backbone rigidity that their applications are greatly limited. The introduction of long side chains not only enhances their processiblity but also makes useful contribution to discovering new application fields. In this article, a variety of novel aromatic polyimides with flexible side chains were prepared either from new dimines or new dianhydrides to measure the influence of the side chains on structure and properties of the polymers and their new applications as liquid crystal alignment layers, photosensitive polymers, alternating multilayer nano-films and photoluminescent materials are discussed.

In this paper we are concerned with the performance of structural stability of torsion in square cross section of a beam with holes. The critical load is defined as the smallest load at which the equilibrium of the structure fails to be stable as the load is slowly increased from zero. The beams subjected to torsion are frequently encountered in general structures and these forces influence to the stability of structure. The boundary element method is found to be very efficient and accurate for the analysis of torsion problems including complex boundary conditions with respect to its simplicity and generality. In this paper, it is required to derive the boundary element formulation for torsion problem and integrate directly on the discrete boundary. To investigate the validity of the developed computer program, three distinctly solid cross-sections which are elliptical, rectangular and triangular one are analyzed, and comparisons are made with analytical approaches where these can also be used.

Hematologic investigations were made on the blood samples taken from bovine leukemia virus (BLV)-seropositive Holstein-Friesian cattle in Korea, and their absolute lymphocyte count was compared with that of BLV-seronegative cattle. The incidence of persistent lymphocytosis (PL) was also determined. The normal bovine lymphocyte count was established on the basis of studies of 656 blood samples taken three times from 297 seronegative animals aged from 0~6 months to over 5 years at 5~6-month intervals. The data were examined according to 7 age groups of samples placed into their respective age groups. A peak in average total count was reached at 6~12 months ($5.36{\times}10^3/{\mu}l$) and thereafter the count declined continuously until over 5 years ($3.17{\times}10^3/{\mu}l$). From the results, 99.74 percent limits were calculated, and the upper limit of the range was chosen as the cutoff point for lymphocytosis. A PL was defined as a lymphocyte count that exceeded the above 99.74 percent limits and persisted over an interval of at least three months. The criterion for PL was applied to classifying 515 blood samples obtained four times from 189 seropositive animals without clinical signs at 5~7-month intervals. It was found that 54 (28.5%) of seropositive animals were with PL; cattle with PL were in age groups of 2~3 years to over 5 years.

Objective: Independent walking is the most essential prerequisite to maintain quality of life in older persons. The purpose of this review was to investigate the effect of fall prevention strategies on fall risk for type 2 diabetes mellitus (T2DM) within community-dwelling older adults aged 65 and over. Design: A systematic review and meta-analysis. Methods: PubMed and three other databases were searched up to October 31st, 2018 and randomized controlled trials (RCTs) evaluating fall prevention strategies for fall risk in persons who were 65 years of age or above with T2DM were included. The review extracted the following information from each study selected: first author's surname, published year, country, study population, type of intervention, intensity of intervention, comparison, measurement variables, additional therapy, summary of results, and mean and standard deviation from selected studies. Results: This review selected fourteen RCTs with 460 older adults with diabetes mellitus. Of the 14 studies, the types of intervention used to improve the risk of falls were strengthening (5), aerobic exercises (2), multimodal exercises (4), one virtual reality exercise (1), whole body vibration with balance exercise (1), and Tai Chi exercise (1). Seven RCTs were eligible for the meta-analysis. Therapeutic interventions were more effective than the control group for the Timed Up-and-Go test (-1.11; 95% CI, -1.82 to -0.41) and the 6-minute Walk Test (-1.89; 95% CI, -8.33 to 4.54). Conclusions: The results of the review suggest that interventions to prevent fall risk in older adults with T2DM should focus on strengthening, balance, aerobic, and multimodal exercises.

Purpose: The purpose of this review was to analyze the effectiveness of complementary and alternative therapies (CAT) as nursing interventions for patients with osteoarthritis (OA). Methods: A systematic literature review was conducted using the PRISMA statement guidelines. To search for studies related to the effects of CAT applied as nursing care in OA patients, a combination of the keywords 'osteoarthritis,' 'complementary and alternative therapy,' and 'nursing care' were used. Finally, 12 articles retrieved from five electronic databases were included for the analysis. Results: Twelve studies were classified into seven interventions: Tai chi exercise, yoga, qigong, massage. flax seed compress, music, and meditation relaxation, administered by a nurse, and were RCTs. Outcome variables used for pain evaluation were WOMAC and VAS. The duration of interventions varied from 2 to 12 weeks. All twelve interventions had a positive effect on the outcome variables. Conclusion: CAT applied in nursing care for patients with OA significantly reduced pain and improved mobility. When planning a nursing intervention program, it is recommended to combine multiple therapies, considering the duration of effects. In addition, it is recommended to design the study as an RCT to secure the evidence for practical application.

In the 1920s, a new religion emerged in Tay Ninh Province, Southern Vietnam, under the name Caodaism; also known as the Third Universal Salvation of the Great Dao. It is the result of the typical combination of three main religions (Buddhism, Daoism, and Confucianism). Different ethnic groups populated Tay Ninh, such as Chinese, Khmer, Cham, and Kinh. Additionally, the core principle of Caodaism is known as The Three Religions Returned to the Origin, and it is also expanded as The Five Branches Reunited. The Five Branches are humankind's five ways of self-cultivation: the Way of Humans, the Way of Deities, the Way of Saints, the Way of Immortals, and the Way of Buddhas. Although Caodaism was only founded in 1920, this religion is well known domestically and internationally. This is because Caodaism has a distinctive identity; it is a new religion that advocates a syncretistic combination of essential religious teachings that follow the harmonization and reconciliation between the East and West as well as between the past and present. Moreover, the Tay Ninh Holy See is the most important, first, and largest Cao Dai temple in Vietnam. The temple is located in Tay Ninh Province in southwestern Vietnam. This article aims to introduce the Tay Ninh Holy See as the birthplace of Caodaism and as the largest Cao Dai religious palace, not only in Vietnam but also in other countries that practice Caodaism. A brief overview of Tay Ninh Holy See's origin, history, and planning will be provided. Most importantly, the style of the architecture at the Tay Ninh Holy See will be comprehensively analyzed to shed more light on the meaning of each section and the details of this temple structure.
