Injuries and pains of musculoskeletal joint in human body is common onset in industrialized world. However, muscle fatigue plays a very significant role in contributing causes of many pains associated with musculoskeletal joints. Based on this hypothesis, degree of muscle fatigue was investigated using electromyography measurement technique during isometric and concentric/eccentric muscle contractions. Different response of the muscle fatigue between two different muscle contractions (isometric and concentric/eccentric contractions) was examined by comparison of parameters which were median frequency, median power and RMS value. Healthy 16 young persons without previous musculoskeletal diesease history were tested with Noraxon Myosystem 2000 EMG measurement system. In this study, two different exercises were performed. First exercise was concentric/eccentric exercise. Second exercise was isometric muscle contraction. In the case of the isometric exercise, median frequency was decreased, but median power and RMS were increased. However, during the concentric/eccentric exercse, median frequency was increased, but median power and RMS were decreased. Both of those revealed that the pattern of the median frequency was W type, but median power and RMS were M type as time passed. In this study, the patterns of the muscle fatigue during concentric/eccentric exercise as well as isometric exercise were identified. It will be helpful to prevent musculoskeletal injury from over-working andexercising.

PURPOSE: To evaluate the long-term results of intravitreal bevacizumab injection for macular edema secondary to branch retinal vein occlusion (BRVO). METHODS: Fifty-six eyes with macular edema secondary to BRVO were treated with intravitreal bevacizumab injection. They were classified into two groups, one group that received three initial intravitreal bevacizumab loadings at monthly intervals and a second group that received only one initial injection. In the two groups, additive injection was performed at recurrence. The best corrected visual acuity (BCVA), central macular thickness (CMT) and retinal ischemic change was analyzed for more than 12 months postoperatively. RESULTS: After 12 months of follow-up, mean BCVA improved and mean CMT reduced significantly in both groups (p < 0.05). However, the range of BCVA improvement and CMT reduction was wider in the three-injection group than in the single-injection group. Fluorescein angiography revealed posterior retinal ischemic changes; bevacizumab didn't seem to aggravate the ischemic change. No drug-related ocular or systemic side effects were observed in the follow-up period after intravitreal bevacizumab treatment except subconjunctival hemorrhage and a mild increase of intraocular pressure. CONCLUSIONS: In patients with macular edema secondary to BRVO, intravitreal bevacizumab injection was a safe and effective treatment, and a more significant visual improvement and reduction of macular edema was achieved after three initial loadings rather than after a single injection.

PURPOSE: This study was done to identify the relationship between goodness-of-fit for mother-preschool child dyads and parenting stress experienced by the mother. METHODS: Study participants were 500 mothers who had children aged 3 to 5 who attended one of ten kindergartens or infant schools in M City or B City. Descriptive statistics and Pearson's correlation coefficients were calculated using the SPSS program. RESULTS: Comparison of goodness-of-fit scores for mother-preschool child dyad according to the characteristics of the participants, showed a significant difference according to child's age, gender, and birth order, mother's education and occupation, father's age and education, family income, and the chief caregiver in the family. There was a positive correlation between goodness-of-fit scores for mother-child dyad and parenting stress scores for mothers. CONCLUSION: The findings of the study indicate a need to identify differences between children's behavioral problems and parenting styles according to the degree of discord in the mother-child temperaments. It is also necessary to develop and apply nursing programs to promote harmonizing of temperaments, programs in which the characteristics of the child and the mother are considered.

PURPOSE: To report a case of retrobulbar hematoma within the lateral rectus muscle which resulted in sight-threatening complication. METHODS: A 40-year-old male presented with a chief complaint of painless mass and exophthalmos. Exicional biopsy via lateral orbitotomy and direct decompression of the muscle were performed to the diagnosis and treatment. RESULTS: After decompression, improvement of the exophthalmos was achieved. This case illustrated a potentially serious complication of retrobulbar hematoma following minor periorbital trauma. The successful outcome may be achieved by rapid diagnosis and intervention.

Synovial sarcoma most commonly affects the extremities, especially the lower thigh and knee region. However, a smaller number develops in a central or axial distribution, an area which encompasses the trunk, orofacial, cervical and parapharyngeal regions. The retroperitoneum is an extremely unusual site and has never been recorded in the literature as primary a site for synovial sarcoma. We investigated a case of retroperitoneal synovial sarcoma in a 40-year-old woman. The specimen consisted of fragmented large bulky multinodular masses separated by slit-like spaces. The tumor was 130 gm in weight. Microscopically, the tumor was composed of nests of plump ovoid to polygonal shaped cells and bundles of spindle shaped cells, which had vesicular nuclei and a small amount of cytoplasm. In some areas, there were cleft like spaces and pseudoglandular structures lined by flat or cuboidal cells. Myxoid change, collagen deposition, foci of calcification and osseous metaplasia were also present. Immunohistochemically, the polygonal cells and some of the spindle cells reacted positively for keratin. The spindle cells, especially in the perivascular area were positive for vimentin. S-100 protein and GFAP were negative in both type of cells.
