This study was aimed to elucidate the relationship between combinations of treadmill speed-grade and oxygen consumption(Vo2). Twenty athetic and 20 non-athletic male college students aged 19-24yr were employed to exercise on a treadmill using 4 speeds(4.02, 5.47, 6.76 and 8.05km/h) and 5 grades(0, 8, 12, 16 and 20%). A fixed speed was selected for each session with the grade increased every 3 min. The Vo2, heart rate, stride frequency and stride length were measured during the last min of each 3-min stage. Vo2increased linearly with increasing speed and grade showing significant multiple correlations in nonathletes(Vo2=3.64x+0.831y+0.031xy-7.03, R=0.98, P<0.01) and athletes(Vo2=3.48x+0.324y+0.112xy-5.74, R=0.99, P<0.01). Stride frequency and length tended to increase with increasing speed except for the transition from walking to runnig at 8.05Km/h at which the stride frequency ran up much higher with the stride length getting lower than at 6.76Km/h. Heart rate increased linearly with increasing Vo2. The rate of increase was higher during walking than during running. These results indicate that athletes have higher rate of increase in Vo2than nonathletes at near-maximal exercise and may be used as a guideline in predicting maximum oxygen comsumption and in prescribing exercise intensity.

PURPOSE: The purpose of this study is to provide the basic data to develop the effective nursing intervention for the parent who have children with cancer by acquiring the deeper understanding of the mothers' adjustment of caring for their children with cancer. METHODS: The ethnographic research method was used to find out the pattern of caring adjustment in Korean cultural context. Informants consisted of 12 mothers who were caring for their children with cancer. The data were collected using in-depth interviews, participant observation, and telephone interviews by maximum variation purposive sampling. The data were analyzed following Spradley's methodology. RESULTS: The mothers' caring adjustment were organized into one cultural theme, four categories, and twelve properties. The cultural theme was 'standing alone as a mother with sin'. The four categories were 'blaming for falling illness', 'overcoming with motherhood', 'desperate struggling with side effects', and 'establishing new network as a dependent'. CONCLUSION: For the mothers who are caring children with cancer, the supportive nursing intervention based on the deeper understanding of mothers' pattern of caring adjustment for their children and centered on facilitating effective adjustment in each cultural context especially from the very early stage of caring in the hospital ward is extremely required.

BACKGROUND: It is well-known that organic solvents can cause various neurologic toxicities, and in particular, it had been reported that Parkinson's syndrome can be caused by organic solvents. CASE REPORT: A 53-year-old man who had worked for 13 years as a shipyard spray and brush painter and manifested with moderate cognitive disorder and was diagnosed with chronic toxic encephalopathy. We can assume he had had considerable exposure to organic solvents considering the estimates of the amounts of organic solvents in his work place. He had no specific medical history. The Minnesota Multiphasic Personality Inventory (MMPI) showed mild cognitive deficit, depression, and anxiety. Single Photon Emission Computed Tomography (SPECT) indicated a slightly decreased flow at the edge of the left temporal brain area, while T2 brain Magnetic Resonance Imaging (MRI) showed no specific signs except for ischemic changes in small vessels in the periventricular and subcortical white matter. He was also diagnosed with both carpal tunnel syndrome and peripheral neuropathy through a neuroconductive study. Several years later, he developed progressive bradykinesia and rigidity and, later, resting tremors in the left hand. He was diagnosed with Parkinson's disease and treated with dopaminergic agents, but there was no effect. After that, he was given deep brain stimulation, both. As a result, his tremor is improved. but, the rigidity remained. Three years later, He has continuously received dopaminergic therapy. but, he complains about tremors in both hands and more greatly reduced cognitive function. CONCLUSION: In this case, we assumed by patient's work history and exposure estimates that he was exposed to excessive levels of organic solvents. The clinical symptoms of this patient were very similar to those from Parkinson's disease, but the psychological symptom appeared earlier than the other symptoms and there was no response to dopaminergic agents. We conclude that this case is likely Parkinson's syndrome caused by organic solvents.

BACKGROUND: Through the control of tuberculosis at 22 public health centers under the National Tuberculosis Control Program, this study is purposed to examine the situation of the tuberculous patients and the characteristics of the therapeutic regimens. METHODS: The data was obtained from 8091 medical records of pulmonary tuberculous patients who were registered for treatment at public health center in Seoul during the year of 1993. It was comparatively analysed by the general characteristics(gender, age, chest X-ray findings, sputum results, treatment results, side effects, combined diseases and accompanied extra-pulmonary tuberculosis) according to various regimens of the tuberculosis. RESULTS: The male patients were 5144, the female were 2947. 34.1% of patients were between 21 and 30years of age. Short course regimen was 97.1% and long course regimen was 2.9%. According to chest X-ray findings minimal 53.5%, moderately advanced 41.2%, far advanced 5.3%. Sputum AFB negative was 52.2% and positive was 47.8%. Therapeutic efficiency was high in short course regimen. Among the side effects, dermatologic problems was high and at the regimen of EHRZ side effects were developed highly. Combined diseases were liver diseases(5.2%), DM(4.2%). Accompanied extrapulmonary tuberculosis were pleurisy(5.4% ), superficial lymphadenitis(0.4% ). CONCLUSIONS: There was great effects in the treatment of tuberculosis with short course regimen in the National Tuberculosis Control Program. But only 38% among the expected patients were treated in this country. So the greater efforts were needed to find and treat more patients effectively.

Purpose: This study examined the association between nurse staffing and in-hospital 30-day mortality among stroke patients considering the stroke type in the intensive care units in Korea using the Health Insurance Review and Assessment Service-National Inpatient Sample 2018 (HIRA-NIS 2018). Methods: The data included a total of 2,876 stroke patients admitted to intensive care units across 72 general hospitals and 39 tertiary hospitals between January and November 2018. Nurse staffing levels were measured using the nurse staffing grades of adult intensive care units in the 2nd quarter of 2018. The relationship between nurse staffing levels and mortality were analyzed using multi-level logistic regression analysis after controlling for patient and hospital characteristics. Results: In patients with ischemic stroke, the risk of death was lower in nurse staffing Grade 5 to 6 compared to Grade 1 (Odds ratio [OR] 0.43, 95% Confidence interval [CI] 0.24~0.75). In hemorrhagic stroke patients, the risk of death tended to be higher in nurse staffing grade 5 to 6 compared to Grade 1 (OR 2.11, 95% CI 1.00~4.45), which was marginally significant (p=.050). Conclusion Health policies for adequate nurse staffing in intensive care units should be implemented to enhance the quality of care and lead to better outcomes in patients with stroke.

PURPOSE: This study examined the mediating effects of self-esteem and resilience on the relationship between internalized stigma and quality of life in people with schizophrenia.METHODS: The participants were 123 people with schizophrenia (mean age = 41.87 years; 62.6% men) recruited from Soonchunhyang university hospital, a mental health center, and daytime rehabilitation facilities located in Seoul and Gyeonggi Province in South Korea. Using a cross-sectional survey, participants completed structured questionnaires with psychometric adequacy. The regression method of Baron and Kenny was used to test the mediating effects of self-esteem and resilience on the relationship between internalized stigma and quality of life.RESULTS: Self-esteem and resilience were found to be full and partial mediators, respectively, in the relationship between internalized stigma and quality of life.CONCLUSION: The findings of this study imply that effective future intervention strategies should target improvements in self-esteem and resilience to reduce the negative impact of internalized stigma on the quality of life of people with schizophrenia.

POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal M protein, and skin lesion) is a rare multisystemic disease of unknown cause with varying clinical manifestations. Amyloidosis-associated POEMS Syndrome is also rare condition. We experienced a 63-year-old female who had been suffered from edema and tingling sensation of low extremities. She also had a marked demyelination, axonal degeneration and regeneration of the nerve, hypoaldosteronism, hyperprolactinemia, decreased sexual hormone, monoclonal gammopathy (IgG lambda type), skin change and ascites. The renal biopsy revealed homogenous mesangial widening with a few cell nuclei at the glomerular capillary, and it showed positive apple-green birefringence in Congo-red stain. It's the first report that shows the deposition of amyloid in patients with POEMS syndrome in Korea. Edema and M-spike were improved by use of prednisolone, melphalan, fludrocortisone and colchicine.

Status epilepticus has been occasionally reported as a cause of acute disseminated intravascular coagulation(DIC), but little is known regarding the pathogenesis of this uncommon association. The occurrence of DIC in status epilepticus may be related to widespread endothelial damage secondary to seizure-induced hyperpyrexia or status epilepticus due to high fever. We experienced two cases of status epilepticus accompanying fever in which laboratory data demonstrated activation of coagulation and fibrinolytic systems in a 3-year-old girl and a 12-month-old boy. There was no evidence of infection, trauma, brain damage, or toxic ingestion as alternative explanations for the consumptive coagulopathy. Hematologic parameters did not improve despite multiple transfusions of red blood cells, pletelets, and fresh frozen plasma. Body temperature should be monitored closely in patients with status epilepticus and efforts directed toward prompt lowering of body temperature to prevent the development of consumption coagulopathy.
