Brachial amyotrophic diplegia, a relatively stable variant of motor neuron disease, is characterized by weakness that is isolated to upper limbs and spared lower extremities, respiratory and bulbar musculature. This disease should be differentiated from other disease such as multifocal motor neuropathy, amyotrophic lateral sclerosis, monomelic amyotrophy and progressive muscular atrophy. We report two cases of brachial amyotrophic diplegia.

The objective of this research work is to investigate the influence of process parameters, such as power of laser, travel speed of laser and material thickness, on roughness and striation of the cut surface for the case of cutting of CSP IN sheet using high power Nd:YAG laser with continuous wave (CW). In order to find the practical cutting region and the relationship between process parameters on the roughness and the striation, several laser cutting experiments are carried out. From the results of experiments, the allowable cutting region and an optimal cutting speed for each cutting condition have been obtained to improve the quality of the cut surface. In addition, it has been shown that the surface roughness is related to the number of striation and depth of valley of the cut surface.

The objective of this research work is to investigate into static characteristics of ISB panels with the pyramidal structure as a internally structured material. In order to investigate the behavior of material deformation and frracture characteristics, several tensile tests have been carried out for the ISB panel and skin sheet. Through the results of the experiments, the mechanical properties of ISB panel and skin sheet and fracture characteristics have been obtained. In addition, the mechaical properties of the ISB panel have been compared with that of the skin sheet by the view point of a specific modulus, a specific yield strength and a specific strength. From the results of the comparision, it has been shown that the ISB panel has an excellent static characteristics.

Bacterial meningitis is frequently fetal or lead to severe neurological impairment. Cerebral infarction is a well known sequele of meningitis, occurring in as many as 10-20% of patients. But fetal cerebral infarction in bacterial meningitis is rare. We report a 61 year old woman who was admitted due to fever, headache and mental change for 3 days. On admission 7 days follow up Brain-CT revealed large and massive infarctions on both hemispheres. When bacterial meningitis is caused by Streptococcus pneumonia, there is a high prevalence of cerebral infarctions. The underlying mechanisms of cerebral infarction in bacterial meningitis are vasculitis, thrombosis, arachnoiditis, and compression of the arterial supply at the foramen magnum by herniation of the cerebellar tonsil.

Major cardiovascular complications of diabetes are coronary atherosclerosis, diabetic dilated cardiomyopathy, autonomic neuropathy and those are major causes of morbidity and mortality in diabetic patients. Gated blood pool heart scan is noninvasive and useful method for evaluation of functional status of heart in diabetics. We evaluated 52 patients with diabetes and divided 3 groups. Group 1 were 11 patients without proteinuria or with proteinuria less than 550mng during 24 hours. Group 2 were 9 patients with proteinuria more than 550mg during 24 hours and group 3 were 32 patients with endstage renal diasese due to diabetes. We performed 99mTc-HSA cardiac gated blood pool scan and used left ventricular ejection fraction(LVEF), peak ejection rate(PEF) to indices of LV systolic function and peak filling rate(PER) to index of LV diastolic function. The results were follows : 1) LVEF, PER were significantly lower in diabetics with ESRD than diabetics without ESRD, but there were no significant difference between normal controls and diabetics without ESRD 2) PFR was significantly lower in diabetics than normal controls, but there were no significant differences in diabetics with or without nephropathy. 3) There were negative correlation between PER, PFR and duration of diabetes. On the basis of results, PFR is a LV functional index of GBPS which can disclose early change of LV dysfunction in patients with diabetes.

Purpose: The purpose of this study was to determine the effect of direct functional magnetic stimulation (FMS) of affected spinal cord on motor recovery following spinal cord injury in rats. Methods: After a contusion injury at the spinal level T9 using an NYU Impactor, functional magnetic stimulation was delivered by a magnetic stimulator through a round prototype coil (7 cm in diameter). Stimulation parameters were set as follows: repetition rate = 50 Hz (stimulus intensity 100% = 0.18 T), stimulation time = 20 min. Functional magnetic stimulation was administered twice a day, 5 days per week for 8 weeks starting 4 days after spinal cord injury. Functional magnetic stimulationwas delivered directly to the affected spinal cord. Outcomes of locomotor performance were assessed by the Basso Beattie Bresnahan (BBB) locomotor rating scale and by an inclined plane test weekly for 8 weeks. Results: In the BBB test, hindlimb motor function in the Functional magnetic stimulation group improved significantly more compared to the control group at 3, 4, 6, 7, and 8 weeks (p<0.05). In the inclined plane test, the angle of the plane in the functional magnetic stimulation group increased significantly more compared to the control group at 4, 5, 7, and 8 weeks (p<0.05). Conclusion: Our results demonstrate that direct Functional magnetic stimulation of the lesional site may have beneficial effects on motor improvement after spinal cord injury.

Background: Written action plans is important for better asthma control. But it is not easy to follow action plan in real life, especially in acute exacerbation. Many people including the elderly are using smartphone more and more: “anytime, anywhere”. We evaluated the usefulness of asthma self-management using an interactive smart-phone based action plan. Methods: Seventy adult asthma patients were enrolled prospectively between November 2012 and February 2013. Patients input their daily asthma symptoms and peak expiratory flow rate on the smart-phone application and instantly received feedback on asthma control status according to an asthma action plan. After 3 months periods of smart-phone guided self-management, we evaluated lung function, Asthma Control Test (ACT) score, Quality of Life Questionnaire for Adult Korean Asthmatics (QLQAKA) score and user`s satisfaction for the smart-phone application. Results: Total 3669 signals generated for 12 weeks and half of the patients (49.2%) used the smart-phone application at least once a day. After 3 months of study, FEV1 (91,6±20.6 vs. 87.3±18.0, p=0.002), ACT score (22.2±2.7 vs. 20.2±4.7, p<0.001), QLQAKA score (72.8±11.4 vs. 67.4±12.3, p<0.001) and medication adherence (94.1±10.1 vs. 86.0±18.1, p=0.001) were significantly improved. Total 22 of risky or dangerous signals in 19 patients (32.2%) were detected and investigators contacted the patients instantaneously by telephone. Among them, two patients were referred to emergency department. The mean satisfaction score for smart-phone guided self-management was excellent (4.0±0.6, range: 1.0-5.0). Conclusion: In real life, the interactive smart-phone based action plan was helpful in managing asthma and especially in acute asthma exacerbations.
