Objectives : This study was performed to evaluate the effects of moxibustion on cerebral blood flow, peripheral blood flow and blood pressure. Methods : We designed a randomized, cross-over study that included 20 healthy, male volunteers who were randomly assigned to one of two groups (the moxibustion group or the control group). The initial trial was followed by a washout period of one week before the groups were switched and the trial repeated. The cerebral blood flow and peripheral blood flow of the volunteers in both groups were measured by mean velocity (Vm), peak systolic velocity (Vs), pulsatility index (PI), perfusion units (PU) and mean blood pressure (BP) before the intervention (baseline), 30 minutes after the intervention, and again 60 minutes after the intervention. Results : 1. The Vm increased significantly in the moxibustion group. The Vs also constantly increased in moxibustion group, but there was no significant difference. 2. The PI decreased significantly in the control group at 0-30 minutes and in the moxibustion group at 30-60 minutes. 3. The PU constantly decreased in moxibustion group. In control group, the PU decreased at 30 minutes and increased slightly at 60 minutes. 4. The mean blood pressure did not show any significant difference between the two groups. Conclusions : This study shows that moxibustion at CV12 increased the cerebral blood flow. Based on this result, we can suggest that moxibustion at CV12 might be helpful in improving the functional recovery of stroke patients. However, further research needs to be conducted on a larger numbers of subjects in order to confirm these effects.

This study was performed to examine the presence of dysphagia and analyze characteristics of the symptoms in cerebrovascular accident(CVA) patients without awareness of dysphagia. A questionnaire for this study was given to CVA patients who had visited P rehabilitation medical center in Busan. Eleven patients (4 males and 7 females) who answered no awareness of dysphasia were given to VFSS, functional dysphasia scale, and NCSE. Descriptive statistics and Pearson correlation analysis were performed by SPSS 12.0. All of subjects without awareness of dysphasia showed characteristics of dysphasia symptoms. Prominent dysfunctions were problems in oral phase and delay of swallowing reflex in pharyngeal phase. For the aspect of cognition, they showed lower score in construction, memory, and similarity than other NCSE items. There was highly significant correlation between orientation, judgment and delay of swallowing reflex. Verbal comprehension and residual materials in oral cavity showed closed correlation. CVA patients without awareness had dysphagia with high probability. The early evaluation of dysphagia should be performed in CVA patients in order to prevent complications due to CVA, so it is necessary to increase the effectiveness of rehabilitation therapy.

Purpose: Confronting the growing burden of dementia requires understanding the causes and predictors of dementia in order to develop preventive strategies. In Korea a large proportion (71%) of dementia is Alzheimer's disease, and the risk factors have not yet been elucidated. Dietary factors may be possible risk factors, however research on the relationship between Alzheimer's disease and dietary behaviors has been insufficient. The purpose of this study was to investigate the association between compliance with the "Dietary Guidelines for Elderly (The Ministry of Health and Welfare, 2011)" and Alzheimer's disease among Korean elderly. Methods: Elderly persons who visited a University hospital or a dementia center of Seoul and agreed to participate in the examinations were selected. Among 277 subjects, 89 Alzheimer patients were selected with diagnosis and 118 subjects were assigned to the control group. Diagnosis of Alzheimer's disease was based on Alzheimer's disease criteria of Diagnostic and Statistical manual of Mental Disorders, 4th edition (DSM-IV) and criteria of National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and related Disorders Association (NINCDS-ADRDA). Information on the general characteristics, health related behaviors and compliance with the dietary guidelines for Korean elderly was collected by face to face interview using a structured questionnaire. Anthropometric variables were measured during the survey. Results: Total compliance score of dietary guidelines was significantly lower in the Alzheimer's disease group than in the control group (p = 0.0001). The odds ratio of Alzheimer's disease was significantly decreased in the group with the highest dietary guideline compliance score (OR = 0.47, 95 % CI = 0.18~1.09) compared to the group with the lowest compliance score. Conclusion: The results indicate that increasing compliance with the dietary guidelines could be an effective strategy to decrease the risk of Alzheimer's disease among Korean elderly.

The purpose of this study was to identify the influence of depression, social isolation, and meaning in life on the swallowing related quality of life in patients with dysphagia. In this study, 87 the dysphagia patients diagnosed with stroke, degenerative disease, and neurological disorder in a general or rehabilitation hospital in Seoul, Gyeonggi, and Incheon were assessed. The data were collected between February and April, 2015 using CES-D, RULS, PIL, SWAL-QOL. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation, and stepwise multiple regression with SPSS 22.0. Of the participants, 20.7% reported having had depression, 92.0% middle-high social isolation and 64.4% existential vacuum. The mean scores were SWAL- QOL 158.89(35.97). Stepwise multiple regression revealed that tube feeding to have the greatest effect on SWAL-QOL(${\beta}=-0.57$, p<.001), followed in order by age (${\beta}=0.26$, p=.001), lower MIL (${\beta}=0.19$ p=.014), and education (${\beta}=0.17$, p=.032). The most influential factor to SWAL-QOL was tube feeding. These variables accounted for 50.7% of SWAL-QOL in dysphagia patients (F=28.84 p=.031). Therefore, it is essential to develop the intervention that can improve the meaning in life in patients with dysphagia. In addition there is a need to study the psychological factors and quality of life of tube feeding.
Purpose : In order to study the effectiveness of East-West pain treatment on central poststroke pain(CPSP), we evaluated its effect on alleviation of pain and rehabilitation of CPSP patients who were treated with eletroacupuncture and west pain treatment for four weeks. Methods : Twenty four patients diagnosed by their pain characteristics of central pain form stroke were treated with sympathetic nerve block, gabapentin, amitriptyline, and electroacupuncture for four weeks. Pain intensity through the visual analogue scale(VAS), and improvements of mobility and rehabilitation through the modified Barthel index(MBI) and Rankin scale(RS), respectively, before and after pain treatment were also assessed. Results : VAS pain scores were significantly improved from $7.7{\pm}1.7$ to $4.4{\pm}2.0$ with pain treatment(p<0.05). In accordance with improvement of ain scores, RS and MBI scores ere also improved from $2.88{\pm}0.95$ to $2.13{\pm}1.01$ and from $83.0{\pm}16.9$ to $94.7{\pm}9.5$(p<0.05), respectively, with pain treatment(p<0.05). Conclusions : It was suggested that the active pain treatment was contributed to the rehabilitation of CPSP patients, resulting in improvement of quality of life of CPSP patients. Futhermore, East pain treatment in combination with West pain treatment may be useful modality to alleviate CPSP.
When the eldery with limited mobility and disabled use a wheelchairs to move, it can cause decreased exercise ability like decline muscular strength in upper limb and lower extremities. The disabled people suffers with spinal cord injuries or post stroke hemiplegia are easily exposed to secondary problems due to limited mobility. In this paper, We designed intelligent wheelchair robot system for upper limb and lower extremities exercise/rehabilitation considering the characteristics of these severely disabled person. The system consists of an electric wheelchair, biometrics module for Identification characteristics of users, upper limb and lower extremities rehabilitation. In this paper, describes the design and configurations and of developed robot. Also, In order to verify the system function, conduct performance evaluation targeting non-disabled about risk context analysis with biomedical signal change and upper limb and lower extremities rehabilitation over wheelchair robot move. Consequently, it indicate sufficient tracking performance for rehabilitation as at about 86.7% average accuracy for risk context analysis and upper limb angle of 2.5 and lower extremities angle of 2.3 degrees maximum error range of joint angle.
Background: Gestational trophoblastic neoplasia (GTN) is a spectrum of disease with abnormal trophoblastic proliferation. Treatment is based on FIGO stage and WHO risk factor scores. Patients whose score is 12 or more are considered as at extremely high risk with a high likelihood of resistance to first line treatment. Optimal therapy is therefore controversial. Objective: This study was conducted in order to summarize the regimen used for extremely high risk or resistant GTN patients in our institution the in past 10 years. Materials and Methods: All the charts of GTN patients classified as extremely high risk, recurrent or resistant during 1 January 2002 to 31 December 2011 were reviewed. Criteria for diagnosis of GTN were also assessed to confirm the diagnosis. FIGO stage and WHO risk prognostic score were also re-calculated to ensure the accuracy of the information. Patient characteristics were reviewed in the aspects of age, weight, height, BMI, presenting symptoms, metastatic area, lesions, FIGO stage, WHO risk factor score, serum hCG level, treatment regimen, adjuvant treatments, side effects and response to treatment, including disease free survival. Results: Eight patients meeting the criteria of extremely high risk or resistant GTN were included in this review. Mean age was 33.6 years (SD=13.5, range 17-53). Of the total, 3 were stage III (37.5%) and 5 were stage IV (62.5%). Mean duration from previous pregnancies to GTN was 17.6 months (SD 9.9). Mean serum hCG level was 864,589 mIU/ml (SD 98,151). Presenting symptoms of the patients were various such as hemoptysis, abdominal pain, headache, heavy vaginal bleeding and stroke. The most commonly used first line chemotherapeutic regimen in our institution was the VAC regimen which was given to 4 of 8 patients in this study. The most common second line chemotherapy was EMACO. Adjuvant radiation was given to most of the patients who had brain metastasis. Most of the patients have to delay chemotherapy for 1-2 weeks due to grade 2-3 leukopenia and require G-CSF to rescue from neutropenia. Five form 8 patients were still survived. Mean of disease free survival was 20.4 months. Two patients died of the disease, while another one patient died from sepsis of pressure sore wound. None of surviving patients developed recurrence of disease after complete treatment. Conclusions: In extremely high risk GTN patients, main treatment is multi-agent chemotherapy. In our institution, we usually use VAC as a first line treatment of high risk GTN, but since resistance is quite common, this may not suitable for extremely high risk GTN patients. The most commonly used second line multi-agent chemotherapy in our institution is EMA-CO. Adjuvant brain radiation was administered to most of the patients with brain metastasis in our institution. The survival rate is comparable to previous reviews. Our treatment demonstrated differences from other institutions but the survival is comparable. The limitation of this review is the number of cases is small due to rarity of the disease. Further trials or multicenter analyses may be considered.

A high-throughput electrorefiner has been developed for commercialization use by enhancing the uranium recovery from the reduced metal which is produced from the oxide reduction process. It is necessary to scrap and effectively collect uranium dendrites from the surface of the solid cathode for high yield. When a steel electrode is used as the cathode in the electrorefining process, uranium is deposited and regularly stuck to the steel cathode during electrorefining. The sticking coefficient of a steel cathode is very high. In order to decrease the sticking coefficient of the steel cathode effectively, vibration mode was applied to the electrode in this study. Uranium dendrites were scraped and fell apart from the steel cathode by a vibration force. The vibrational scraping of the steel cathode was compared to the self-scraping of the graphite cathode. Effects of the applied current density and the vibration stroke on the scraping of the uranium dendrites were also investigated.
Since mid-1960s the reports from the Surgeon General, the World Health Organization, and other health experts state that there is no risk-free level exposure to smoking and secondhand smoke. Tobacco smoke is made up of more than 7,000 chemicals. Hundreds are toxic, and at least 70 are carcinogens. The chemicals in tobacco smoke reach smoker's lungs quickly every time smoker inhale causing damages immediately. Inhaling even the smallest amount of tobacco smoke can also damage smoker's DNA, which can lead to cancers. Smoking is responsible for more than 87% of lung cancers, but there are a host of other chronic diseases directly related to exposure to tobacco smoke. It's also a major cause of heart disease, stroke, aortic aneurysm, peripheral arterial disease and most of the other diseases. In the United States, each year with more than from 440,000 to 520,000 deaths caused by smoking and exposure to involuntary smoke. They conclude that smoking is the single most important source of preventable morbidity and mortality. The United States of America have about 60-year history of tobacco litigation. Tobacco litigation has been an important tool in tobacco control strategies aimed at limiting the activities of tobacco companies and providing redress to people who have become ill as a result of their use of tobacco products. Tobacco litigation is a kind of tort litigation. Quite often, as in the asbestos and other mass tort litigation episodes, tobacco litigation can play an educational role, warning the public about the magnitude of health risks that might otherwise be less clearly perceived. Tobacco litigation allows smokers, their families or other victims of smoking to sue tobacco companies in order to be compensated for the harm they have suffered. Potential benefits of tobacco litigation include compensation for smoking-related damages, strengthening regulatory activity, publicity, documents disclosure and changing tobacco industry behavior. And also tobacco litigation can limit the political activities of tobacco industry, protect human rights of smokers and non-smokers, increase burden to tobacco price-up and enhance the effects of law and politics in public health.
