Correct discrimination of the first and the second twin is important. Case: (1) The first fetus, whose amnionic cavity was closest to the cervix at 19 weeks, even though its body was higher than the second fetus, was found to be closer to the cervix by 23 gestational weeks than its twin. (2) The result of the chromosomal study of dichorionic twins at 17 gestational weeks was male with 9 inversion of the presumed first, and female with trisomy 21 of the presumed second. AT 19 gestational weeks, the sex and order of the two were found to be reversed at sonography for selective termination. In diamnionic twins, the fetus in the amnionic sac closest to the cervix is nominated as the first.

Low back pain patients an controls of shipyard workers were surveyed between June 1995 and september 1995 to identify risk factors of industrial low back pain. The patients were 17 male workers who had got medical treatment for over 3 days because of industrial back pain controls were 51 male workers who had not have musculoskeletal disorder for one year before the survey. By univariate analysis, the workers who did overtime work 4 times or more for the last 2 weeks showed odds ratio of 3.67 on low back pain with the workers who did less overtime work. Carrying heavy materials was also associated with the low back pain and the odds ratio increased with the increase of carrying weight. work space and work posture were not associated with the low back pain significantly. The welder had higher odds ratio than the other workers on low back pain. The duration of employment and job satisfaction did not affect the risk of low back pain. Multiple logistic regression analysis showed that frequency of overtime work for the last 2 weeks and carrying heavy materials among the risk factors were associated significantly with the low back pain. We found that important risk factors of low back pain of shipyard workers are work intensity factors such as overtime work and carrying heavy weight.

Purpose: : This descriptive survey aims to identify the prevalence of factors associated with sarcopenia among hemodialysis patients. Methods: : The study subjects were 137 patients with chronic kidney failure undergoing hemodialysis in three artificial kidney centers in B and Y cities. Data were collected from August 1 to September 30, 2020, using the SARC-F (Strength, Assistant walking, Rising from a chair, Climbing stairs, Falls) questionnaire, Mini Nutritional Assessment-Short Form (MNA-SF), International Physical Activity Questionnaire (IPAQ-SF), Bioelectrical Impedance Analysis (BIA), and a grip dynamometer. The collected data were analyzed using t-tests, crossover analysis, and logistic regression using the IBM SPSS 23 program. Results: : The prevalence of sarcopenia among hemodialysis patients, determined using the SARC-F questionnaire, was 16.1%. The associated factors of sarcopenia among hemodialysis patients were found to be gender (OR=6.44, p =.002), age (OR=1.07, p =.015), nutritional status (OR=10.37, p =.027), and albumin level (OR=0.10, p =.014). These findings are supported by an explanatory power of 46.3% (p =.597). Conclusion : The identified risk factors for sarcopenia in hemodialysis patients were; sex, age, nutritional status, and albumin level. The findings of this study can serve as clinical evidence for the development of an intervention program for preventing and managing sarcopenia in patients undergoing hemodialysis.

A 33-year-old-woman with twin pregnancy underwent genetic amniocentesis in our hospital at 16 weeks of gestation. Fetal chromosomal analysis showed 46,XY,inv(9) and 47,XX,+21. The affected twin was terminated by ultrasonographically guided intracardiac injection of 3 ml potassium chloride solution at 19 weeks of gestation. A healthy 2570 g male infant was born by cesarean section with Apgar scores of 8 and 9 at one and five minutes, respectively.

PURPOSE: This study was to identify the effects of Nei-Guan accupressure using a wrist band on postoperative nausea and vomiting after middle ear surgery. METHODS: The study design was a nonequivalent control group non-synchronized posttest design. Forty patients were assigned into two groups of 20 patients, the wrist band group and the control group. In the wristband group, acupressure was applied with a wrist band on the P6 point at both wrists from 30 min before to 24 hr after anesthesia. RESULTS: The 1st hypothesis 'Applied wrist band groups will have a greater reduction in the nausea & vomiting grades by INVR than the control group' was accepted (t=2.303, p=.028). The 2nd hypothesis 'The Applied wrist band groups will have a greater reduction in the occurrence of nausea & vomiting than the control group' was partly accepted. The 3rd hypothesis 'The applied wrist band group will have a greater reduction in injection of antiemetics for 24 hr. post anesthesia than the control group' was rejected. CONCLUSION: Acupressure on the P6 point using a wrist band is effective to alleviate nausea for middle ear surgery patients.

Optic nerve gliomas manifest either as a solitary form or a component of von Recklinghausen's neurofibromatosis. The reported incidence of coexistence with neurofibromatosis varies from 12% to 70%. Usually there are no significant cytological differences between the gliomas that accomapny the disease and those that are deemed to be solitary manifestations. The only possible difference between them is the apparently more common association, with the former, of extensive arachnoid hyperplasia and of a more florid local gliomatous infiltration into the leptomeninges, altogether resulting in perineural thickening. Our cases were 8 and 6 years old girls, respectively, presented with slowly progressive proptosis for 4 years and visual disturbance for 2.5 months. There were multiple cafe au lait spots on their trunks, and case 2 showed Lisch nodules in the iris. MRI of brain revealed unilateral optic nerve thickening with involvement of chiasm or multiple intracranial lesions. Resection of optic nerve tumor was performed. Microscopically, variable degree of tumorous change was seen. Most typically enlarged area was composed of intraneural and perineural portions surrounded by a layer of intact dura. Intraneural tumor revealed proliferation of elongated, spindle-shaped pilocytic astrocytes in intertrabecular spaces and distention of the pial septa with fibrovascular thickening. Another segment had areas with reactive gliosis. Perineural tissue was considerably thickened and, associated with proliferation of meningothelial cells and fibroblasts intermingled with astrocytes and Rosenthal fibers. There were increase of the optic nerve diameter and distention of the overlying dura. Foci of arachnoid cell hyperplasia were noted in both cases, although differed in degree. Immunohistochemically, the tumor cells expressed glial fibrillary acidic protein in intraneural and perineural portions particularly in case 2.

PURPOSE: This study was conducted to determine the predictors of employment intention for mentally disabled persons. METHODS: Mentally disabled persons who had participated in rehabilitation programs in one of 16 mental health centers and 9 community rehabilitation centers located in Seoul and Kyunggi province were recruited for this study. A random sampling method was used and 414 respondents were used for final analysis. Data was analyzed by Pearson's correlation, and stepwise multiple regression using the SPSS Win 14.0. RESULTS: The predictors influencing employment intention of the mentally disabled person were observed as employment desire (beta=.48), guardian's expectation (beta=.26), professional's support (beta=.23), financial management (beta=.10), eating habits (beta=.07), and quality of life (beta=-.01). Six factors explained 61.1% of employment intention of mentally disabled persons. CONCLUSION: The employment intention of a mentally disabled person was influenced by employment desire, diet self-efficacy, guardian's expectation, professional's support, quality of life, financial management and eating habits.

Many workers who used coal tar containing paints in shipyard industry have dermatitis, but the etiology is not known well. Our research is to fond out the etiology of the dermatitis and to provide proper management. Methods of this research are comprised of 3 steps. First, we diagnosed dermatitis by questionnaire and dermatologic examination and evaluated air level of coal tar pitch volatiles in workplace. Second, we confirmed coal tar phototoxicity by in vitro cell experiments. Third, we evaluated the effects of intervention. The results were as follows ; Questionnaire survey showed that the lesions of dermatitis were mainly on the sun exposed area and the symptoms were strongly associated with season, weather, and time. Air levels of coal tar pitch volatiles in workplace were higher than NIOSH standard (0.1 mg/m(3), cyclohexane solubles). Inhibitory effects of cellular proliferation by coal tar containing paints and UVA (365nm) exposure showed coal tar phototoxicity. Intervention was done by UV barrier cream(BPF 30) and 72.7% workers who applied UV barrier cream improved after 2 months later. Conclusively, the etiology of dermatitis of shipyard workers who used coal tar containing paint was coal tar phototoxicity, and this dermatitis would be protected by UV barrier cream.
