Purpose: We assess the mid to long term follow up results of arthrodesis of the first metatarso-phalangeal (MTP) joint and resection arthroplasty of the lesser toes in rheumatoid arthritic forefoot deformity. Materials and Methods: Between 1998 to 2001 year, 25 cases (18 patients) rheumatoid forefoot deformities were surgically corrected. Follow up period was 83 months (range, 63 to 90 months). The clinical outcome was evaluated using subjective satisfaction and AOFAS score. The radiological measurements were hallux valgus angle, first and second intermetatarsal angle, second metatarso-phalangeal angle (MTP-$2^{nd}$ angle). Results: Subjective satisfaction was 76%. AOFAS score improved from 37 to 73. The hallux valgus angle improved from preoperative $39^{\circ}$ ($27{\sim}64^{\circ}$) to $14^{\circ}$ ($4{\sim}34$) at the last follow up. The intermetatarsal angle were preoperative $13^{\circ}$ ($6{\sim}22^{\circ}$) to $11^{\circ}$ ($3{\sim}13^{\circ}$) at the last follow up, The MTP-$2^{nd}$ angle were preoperative $24^{\circ}$ ($9{\sim}47$) to last follow up $15^{\circ}$ ($2{\sim}39^{\circ}$) respectively (p>0.05). Complication was intractable callus 10 cases, Interphalangeal arthritis 5 cases. Conclusion: Mid to long term outcomes rheumatoid forefoot reconstruction by first MTP arthrodesis and resection arthroplasty of lesser toes results a satisfaction and pain relief.

Purpose: Flexed posture commonly increases with age in older women and is characterized by an excessive curvature in the thoracic spine (kyphosis), forward head posture, and decline in height. This study was conducted in order to determine the relationship between flexed posture, physical performance, and psychosocial factors in community dwelling elderly women in Korea. Methods: Fifty-two subjects with thoracic kyphosis of $40^{\circ}C$ or greater participated in this study. Flexed posture was measured using kyphosis angle (KA), forward head posture (FHP), and round shoulder (RS), and physical performance was evaluated using the short physical performance battery (SPPB), grip strength, and static and dynamic balance. Psychosocial factors were measured using depression and the quality of life (QOL). All data were analyzed using SPSS 18.0 software for windows. Results: KA showed significant correlation with SPPB score (r=-0.447) and dynamic balance (r=0.426) (p<0.05) depression (r=0.405) and QOL (r=-0.464) but not with grip strength and static balance in elderly individuals. FHP and RS showed significant correlation with SPPB score (r=0.002, r=-0341) and dynamic balance (r=-0.278, r=0.346) (p<0.05) but not with psychosocial factors. Conclusion: These findings suggest that flexed posture provides meaningful information about physical performance and psychosocial factors in elderly women. Our data suggest that the flexed posture may need to be addressed as part of the health management process for elderly women.

PURPOSE: Balance exercise as well as lower extremity strengthening exercise (LESE) is known to be effective in patients with knee osteoarthritis (KOA). The purpose of this study was to investigate the effectiveness of performing LESE in conjunction with balance exercise on lower extremity function, range of motion, muscle strength, and balance in patients with KOA. METHODS: The subjects of this study were 25 patients with KOA who were recruited and randomly divided into two groups: 1) those who performed LESE with balance exercise; and 2) those who performed only LESE. Both the groups also received general physical therapy and performed aerobic exercise. The interventions were performed 3 times a week for 4 weeks. To determine the effectiveness of the interventions, we measured Western Ontario and MacMaster Universities Arthritis Index (WOMAC) score, numerical rating scale (NRS) score, passive range of motion (PROM), chair stand test (CST), and Berg Balance Scale (BBS) score at the initiation of the interventions and again after 4 weeks, at the time of completion of the interventions. RESULTS: After 4 weeks of the interventions, both the groups showed significantly improved WOMAC (p<.01), NRS (p<.01), PROM (p<.05), CST (p<.05), and BBS (p<.01) scores. However, there was no significant difference between the groups in terms of the clinical outcomes observed. CONCLUSION: These results suggest that the addition of balance exercise to a LESE regimen in patients with KOA did not provide any additional benefit.

Objective : A pilot project entitled '50s mental health screening project' was conducted in Seoul. As a part of this project, we conducted surveys to obtain the opinions of psychiatrists regarding mental health screenings. Methods : A questionnaire was mailed to members registered with the Korean Neuropsychiatric Association, which enquired about the '50s mental health screening project'. Results: A majority (90.9%) of the subjects agreed on the purpose and implementation of the project. However, there were fewer individuals that actually showed the intent to participate (65.8%). The mean age of the group with the intention to participate was higher compared to the group with no intention to participate. The factors that negatively affected the intent to participate included prejudice and discrimination against psychiatry (3.795), low health insurance reimbursement (3.784), and inconvenience of reporting to public health centers (3.664). The most appropriate method that scored the highest for screening mental health was face-to-face consultation with a psychiatrist (3.889). Most of the participants agreed on the method of a self-reported survey along with an interview of psychiatrist (84.9%). Conclusion : Subjects were concerned about prejudice and discrimination against psychiatry, low health insurance reimbursement, and inconvenience of reporting to public health centers. These problems need to be supplemented. Face-to-face consultation with a psychiatrist may be considered an appropriate method for future mental health screening.

Objective : The purpose of this study was to verify the appropriateness of ovariectomized rats as the osteoporosis animal model. Methods : Twelve female Sprague-Dawley rats underwent a sham operation (the sham group) or bilateral ovariectomy [the ovariectomy (OVX) group]. Eight weeks after operations, serum biochemical markers of bone turnover were analyzed; osteocalcin and alkaline phosphatase, which are sensitive biochemical markers of bone formation, and C-terminal telopeptide fragment of type I collagen C-terminus (CTX), which is a sensitive biochemical marker of bone resorption. Bone histomorphometric parameters and microarchitectural properties of 4th lumbar vertebrae were determined by micro-computed tomographic (CT) scan. Results : The OVX group showed on average 75.4% higher osteocalcin and 72.5% higher CTX levels than the sham group, indicating increased bone turnover. Micro-CT analysis showed significantly lower bone mineral density (BMD) (p=0.005) and cortical BMD (p=0.021) in the OVX group. Furthermore, the OVX group was found to have a significantly lower trabecular bone volume fraction (p=0.002). Conclusion : Our results showed that bone turnover was significantly increased and bone mass was significantly decreased 8 weeks after ovariectomy in rats. Thus, we propose that the ovariectomized rat model be considered a reproducible and reliable model of osteoporosis.

Purpose: The purpose of this study was to identify an influence of self-esteem and familysupport on powerlessness of hospitalized elderly patients with chronic disease. Method: The subjects were 151 hospitalized elderly patients, age over 60, with chronic disease and admitted for at least 1 week. The data were collected by individual interview using a structured questionnaire during the period from July 10th to August l0th, 2003 from three general hospitals in Busan. The data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation, hierarchical multiple regression. Result: The level of self-esteem, family support, and powerlessness was 38.00, 38.26, and 38.38, respectively. There was a significant positive correlation between self-esteem and family support and a negative correlation between self-esteem and powerlessness and between family support and powerlessness. Self-esteem and family support were each significant predictor of powerlessness. Conclusion: This study showed the hospitalized elderly patients need greater family-support and higher self-esteem to relieve the level of powerlessness. I suggest to study for replication in a larger sample size and considering the lengths of hospitalization for generalization of this study and to develop individual intervention programs for increasing family support and self esteem and testify their effects on the relief of powerlessness of the elderly.

In the specimen of free PSA in the low concentration, the result in % bias from our institution and comparable evaluation institution was -33.7% which is exceeded % bias ${\pm}20%$ ; however, it was the domestically allowable limit recommended by the laboratory accreditation commission for specimen at the low concentration. In this paper, the cause was accredited by instability of free PSA substance within the specimen, and the specimen stability test was performed according to CLSI documents GP29-A2. After the low and high concentration specimen were made, and rapidly cooled down in a deep freezer with $-30^{\circ}C$, serum of two concentrations was measured for 10 consecutive days with 3 times a day by Architect i2000 and observed a change in the mean value. As the results of two groups, there were changes in the established target value, and a change level was evaluated by calculating it with % bias. The low concentration specimen had no significant reduction until the 4 day lapse in cold storage. However, % bias were reduced by -17.5% from the 5 day lapse, by 21.5% after the 7 day lapse, and by -26.9% after the 9 day lapse. The frozen specimen had only intra-day variation for 10 days. In the high concentration specimen, bias began to show as -12.2% from the 3 day lapse in cold storage. There was reduction by -28.9% from the 5 day lapse, by -39% after the 7 day lapse, and by -42.9% after the 9 day lapse. In the frozen specimen, there was only intra-day variation like the low concentration specimen in cold storage.
