The author present a modified multi-loop algorithm including feedforward for controlling a 55kW step down chopper in the power supply of Maglev. The control law for the duty cycle consists of three terms. The first is the feedforward term which compensates for variations in the input voltage. The second term consists of the difference between the slowly moving inductor current and output current. The third term consists of proportional and integral terms involving the perturbation in the output voltage. This perturvation is derived by subtracting the desired output voltage from the actual output voltage. The proportional and integral action stabilizes the system and minimizes output voltage error. In order to verify the validity of the proposed multi-loop controller, simulation study was tried using Matlab simulink.

This study aimed to investigate the effects of JU Movement Therapy on the pain and depression relief of hemiplegic stroke patients. A total of 24 in patients diagnosed with hemiplegic stroke at R hospital from March to June 2012 were sampled for the study. We first evaluate the general characteristics and subjective symptoms of research participants and then A pre-test was conducted by performing physical an examination on individuals who suffer from pain. The degree of patients’ subjective pain and depression of sample and control groups by Visual Analogue Scale(VAS) and Self Rating Depression Scale. The average and standard deviation of all the variables was first calculated by using SPSS (Ver 18.0) and then paired t-test was conducted to compare the difference between before and after among groups. Finally, the result was analyzed using independent t-test. The level of statistical significance for all tests was p<.05 and the results of studying were as follows: There was decrease of VAS between sample and control groups after experiment. This was the significant difference. Also there was no significant difference in VAS between sample and control groups before the experiment but there was the significant difference after experiment(p=.025). The factors related to physical symptoms on the Depression scale in the sample group showed a significant difference before and after the experiment (p=.015). Factors on psychiatric symptoms also showed significant differences between the pre-and post-test(u=.001)

Objective: This study was designed to evaluate the clinical significance of preoperative serum carcinoembryonic antigen (CEA) as a prognostic marker in epithelial ovarian cancer. Methods: We performed a retrospective review of the medical records of one hundred eleven patients with epithelial ovarian cancer who underwent surgery at Seoul National University Bundang Hospital between June 2003 and March 2009. The correlations of CEA with other tumor markers (CA-125, CA 19-9, and CEA) and clinicopathological prognostic factors (tumor stage, age, residual mass, peritoneal washing cytology and preoperative tumor size) were analyzed. Results: The normal cutoff levels of CEA, CA-125, and CA 19-9 were 5 ng/mL, 35 U/mL, and 37 U/mL, respectively. Of the one hundred eleven patients, only 8.1% of the patients were positive for CEA, and all patients with an elevated CEA level had a high CA-125 level. The sensitivity of CA-125 was 83.6%, and that of CA 19-9 was 21.9%. Correlation analysis between tumor markers and prognostic factors showed that CA-125 correlated significantly with advanced tumor stage, positive washing cytology and presence of a residual mass. CA 19-9 was significantly associated with advanced tumor stage, positive washing cytology, the histological type and preoperative tumor size. However, CEA had no significant correlation with all prognostic factors except the mucinous histologic type. Conclusion: The results of this study suggest that serum CEA may have a limited role in detecting and predicting the prognosis of patients with ovarian cancer. Thus, the preoperative evaluation of serum CEA level may have a limited value in the prognosis of ovarian cancer.

Nebulin is a giant ($600{\sim}900$ kDa), modular sarcomeric protein proposed to regulate the assembly, and to specify the precise lengths of actin filamints in vertebrate skeletal muscles. Recently, There is an evidence that the nebulin also expressed in non muscle tissue, brain and liver. We identified a new isoform of nebulin from adult brain library by PCR screening. It contains two simple-repeats exon 165, 166 and linker-repeats exon $154{\sim}161$ except exon 159. The nebulin modules M160 to M170 (exon 150 to exon 161) has been shown to bind desmin. In mature striated muscle, desmin intermediate filaments surround Z-discs and link individual myofibrils laterally at their Z-discs and to other intracellular structures, including the costameres and the intercalated discs of the sarcolemma, sarcoplasmic reticulum, mitochondria, T-tubules, and nuclei. Therefore, it is an interesting possibility that the differential splice pathways within the linker region of nebulin modify the affinity of nebulin's interaction with desmin. The specific interactions of nebulin and desmin were confirmed in vivo by yeast two hybrid experiments. To verify in the cellular level the interaction between nebulin isoform and desmin, we transfected COS-7 cell with EGFP-tagged nebulin and DsRed-tagged desmin. Based on evidence showing that despite exon 159 was deleted, the new isoform of nebulin was interact with desmin. This suggest that nebulin in brain may interact with another intermediate filament. The conservation of these ligand-binding capacity in brain and skeletal nebulins suggest that nebulins may have conserved roles in brain and skeletal muscle.

Purpose: To determine whether crepitus may be a clinical indication for early temporomandibular joint (TMJ) osteoarthritis (OA) and to investigate the correlation between crepitus and the occurrence of TMJ OA with respect to factors, such as patient sex, age, chewing habits, and diagnosis. Methods: This is retrospective analysis of clinical data for 162 TMJs. The criteria for a joint to be included in this study was a minimum of two cone-beam computed tomography (CBCT) scans performed with no OA observed during the initial scan. The Diagnostic Criteria for Temporomandibular Disorders was used for OA diagnosis. Crepitus was recorded when it was objectively palpated during the follow-up period. Correlations between various patient factors and progression to TMJ OA were calculated using the Pearson's chi-square test. A linear-by-linear association was used to analyze trends of OA progression with increasing age. Results: Among the 162 joints, 101 progressed to OA and 61 did not. In the joints where crepitus had been present before OA was confirmed at next or last CBCT, OA progressed at a high rate, and especially higher in female and older patients (p<0.01). Patients in the pain-related disorder group with crepitus were observed to have higher rates of OA progression compared to patients in the intra-articular disorder group (p<0.01). Conclusions: If a patient experiences pain in the TMJs and crepitus, close monitoring through regular CBCT scans is necessary even if there is no evidence of radiologically confirmed OA after the first CBCT.

Spontaneous Resorption of Lumbar Disc Herniation with Literature Review: Caution before Deciding on Surgery

Jeon Ju Hee,Shin Hong Kyung,Jung Jae Lee 대한말초신경학회 2022 The Nerve Vol.8 No.1

Lumbar disc herniation (LDH) is a common cause of sciatica. Several cases of clinical improvement in patients with spontaneous resorption of LDH have been reported. However, it is uncommon for this spontaneous resorption of LDH to manifest as an abrupt improvement of symptoms. Here, we report a case of rapid symptom improvement due to spontaneous resorption of LDH. Furthermore, we review the available literature to critically evaluate the possibility of spontaneous LDH resorption and consequent symptom improvement within the context of previous research.
