Drawing on its extensive experience with natural disasters, Japan has been dispatching Japan Disaster Relief (JDR) team to disaster-stricken countries to provide specialist assistance in rescue and medical operations. The JDR team has assisted in the wake of disasters including the 2004 Indian Ocean Earthquake and the 2008 Sichuan Earthquake in China. Information about the affected area is essential for a rapid disaster response. However, it can be difficult to gather information on damages in the immediate post-disaster period. To help overcome this problem, we have built on an Earthquake Damage Estimation System. This system makes it possible to produce distributions of the earthquake's seismic intensity and structural damage based on pre-calculated data such as landform and site amplification factors for Peak Ground Velocity, which are estimated from a Digital Elevation Model, as well as population distribution. The estimation result can be shared with the JDR team and with other international organizations through communications satellite or the Internet, enabling more effective rapid relief operations.

Objectives: Minamata disease was an environmental health disaster of worldwide notoriety that occurred in Japan. The acknowledged patients total roughly 3,000, and the relieved victims currently include 77,099 cases. Still, many cases await acknowledgment or relief. The humidifier disinfectant issue is an environmental health catastrophe that took place in Korea. Over 9.98 million products spanning 43 brands of humidifier disinfectant have been sold and 835, cases have been recognized to date as relevant victims by the government. So far, 2,144 cases have been relieved by the fund of the producing companies. Four million consumers and 560,000 victims are estimated. Finding hints as to how to develop solutions in terms of fact-finding and prevention are the objectives of this study. Methods: Fields visits, interviews, and workshops as well as reference reviews have been conducted. A comparison was attempted to show the similarities and differences between the two disasters on 38 items. Results: Apparent similarities in the two disasters are the failure of industrial safety measures and governmental safety systems as well as relief systems for the victims. No comprehensive investigation was performed for all of the affected areas in Japan and all of the consumers in Korea. Both governments have tried to hide the faults and responsibilities of the companies and minimize the scale of the victims. Only after the government was changed through a general election did the new governments apologize and attempt to find political and social solutions through special relief laws. Conclusions: Over the process of each event, in the beginning, debates took place regarding the cause and the heath damages involved. For both, medical and toxicological relations are the keys while afterward finding a social solution became the subsequent issue.

Objectives: Human indices were developed to determine returning point of residents and damage restoration after the chemical accident Methods: To determine the returning point of residents after the chemical accident, a new concept, the standard man model was introduced as a human index, in which both H-code and its acute effects were main idea. To evaluate the applicability, a hydrogen fluoride leakage accident in Gumi was applied. The returning point were suggested as the conservative remission period of acute effects among relevant hazard effects and compared with actual returning point. The coverage of each age group were considered with reflecting average daily dose expected for actual residents. In addition, a relief-index as a social-scientific approach was reflected as well to apply the damage restoration Results: Actual returning point of residents in Gumi was 88 days; and that of standard man model suggested was 84 days. The expected amount of exposure at aged 12 or under was at least 2.35 times greater than that of this model, 40s, theoretically. However, their population ratio was less than 1%, so 99% of residents could be applied when the standard man model was applied. The relief-index was as an objective and quantitative methodology to apply the qualitative aspect. Conclusions: Although evaluated as a relatively positive result, there was a limitation such as the number of accident applied to the verification of standard man model. The relief index was also considered, but further research should be carried out to find threshold level for the relief.

Purpose: The purpose of this study is to assess the effectiveness of short-wave therapy (SWT) for treatment of knee osteoarthritis (OA) as compared to placebo and control, and to assess the question of whether the effects are related to the mode, dosage, and application method. Methods: We searched randomized, placebo-controlled trials using electronic databases. We also manually reviewed sources in order to identify additional relevant studies. Results: Eight studies (597 participants) with OA were included in the meta-analysis. Pulse SWT had a significant effect on pain relief compared with control treatment, while did not favour compared with the placebo group. Pulse SWT had a significant effect on functional improvement compared with control and placebo treatment. Continuous SWT had no effect on pain relief and functional improvement. Capacitive SWT a significant effect on pain relief, functional improvement, and muscle strength. Continuous and capacitive SWT had increased muscle strength significantly. We found no clinical significance of all outcomes except pain and functional improvement in pulsed SWT with low dose. There was no difference in adverse events. None of the participants experienced any serious adverse events. Conclusion: Low dose pulsed SWT provided a short-term clinical benefit for pain relief and functional improvement. Pulsed SWD with low and high dose had effects on pain and function. There seems to be a placebo effect. We found significant effects on pain and function in capacitive SWT. Despite some positive findings, this analysis lacked data on how effectiveness is affected by mode, dosage, and application method of SWT. Further well-designed clinical studies are required in order to confirm the effectiveness of SWT.

Neurolysis of the celiac plexus is performed to relieve intractable pain caused by carcinoma of the stomach, liver and pancreas, and upper abdominal metastasis of tumors having more distant origins. It is also occasionally effective in controlling the pain of chronic pancreatitis. Alcohol celiac plexus blocks were done in 22 patients of whom 18 had intractable upper abdominal pain from cancer and 4 had pain from chronic pancreatitis. In most cases, an initial diagnostic block with 0.2 percent bupivacaine was followed by the therapeuntic block performed by injecting 50ml of 60 percent ethyl alcohol. Good to excellent pain relief occurred in 86 percent of patients. Duration of pain relief was from 4 months to 7 months in 55 percent of patients. Complications and side effects were infrequently seen but did include a 16 percent decrease of mean systolic arterial pressure and 16 cases of facial flushing. This block is remarkably safe as well as effective for the relief of upper abdominal pain from cancer origin.

In an effort to make a functional and stable yogurt, this study investigated the improvement effects of sea tangle extract and sea tangle yogurt on intestinal function. The intestinal improvement effect of the extract was measured by the charcoal meal transit method, employing Balb/C mice. And constipation relief was compared utilizing the loperamide-induced constipation method, employing SD rats. Charcoal meal transit was remarkably increased in the mice receiving sea tangle extract as compared to the controls. The constipation relief effects of the sea tangle and sea tangle yogurt were evaluated by measuring fecal amounts in the rats after adding them to water. The fecal contents increased remarkably in the sea tangle administered rat groups as compared to the control group. In addition, different yogurt samples were used to evaluate the characteristics of the sea tangle yogurt. During storage, pH slightly decreased in the yogurt with sea tangle as well as without. At the same time, acidity slowly increased as the storage duration increased. As time elapsed, the amounts of viable cells increased in both yogurts (with and without sea tangle). In the sensory evaluation, significant differences were shown between the sea tangle yogurt and the control for color, flavor, sweetness, and overall quality. Overall, based on the combined results of the intestinal function effects and sensory evaluation, the 0.25% sea tangle yogurt proved to be superior.

A main goal of pharmacogenomics studies is to predict individual's drug responsiveness based on high dimensional genetic variables. Due to a large number of variables, feature selection is required in order to reduce the number of variables. The selected features are used to construct a predictive model using machine learning algorithms. In the present study, we applied several hybrid feature selection methods such as combinations of logistic regression, ReliefF, TurF, random forest, and LASSO to a next generation sequencing data set of 400 epilepsy patients. We then applied the selected features to machine learning methods including random forest, gradient boosting, and support vector machine as well as a stacking ensemble method. Our results showed that the stacking model with a hybrid feature selection of random forest and ReliefF performs better than with other combinations of approaches. Based on a 5-fold cross validation partition, the mean test accuracy value of the best model was 0.727 and the mean test AUC value of the best model was 0.761. It also appeared that the stacking models outperform than single machine learning predictive models when using the same selected features.

Endometriosis is defined as the presence of functional endometrial tissue outside the uterus, causing diverse progressive symptoms such as infertility, pelvic pain, and dysmenorrhea. Although endometriosis has been described since the 1800s, the mechanisms responsible for its pathogenesis and progression remain poorly understood. It is well established that endometriosis grows and regresses in an estrogen-dependent fashion and the disease can be effectively cured by definitive surgery. However, prolonged medical therapy may be needed in most of the cases since conservative surgery is usually performed especially in young women. This treatment modality is often associated with only partial relief and/or recurrence of the disease. In the present review, up-to-date findings on the treatment of endometriosis will be briefly summarized. The outcomes of surgery in patients with endometriosis will be reviewed in terms of pelvic pain relief as well as infertility treatment largely based on recent Cochrane reviews and clinical reports. The efficacy of newer drugs including aromatase inhibitor, anti-tumor necrosis factor-alpha, and dienogest will be also reviewed based on recent clinical studies.

Buerger's disease is a nonatherosclerotic occlusive inflammatory disease of the small and medium arteries, and veins of the distal leg or arm. Percutaneous lumbar sympathectomy is used to lower extremity occlusive vascular disease as well as Buerger's disease. Lumbar sympathectomy improves blood flow and provides pain relief in the lower extremity. We report two cases of lumbar sympathectomy using radiofrequency thermocoagulation in patients with Buerger's disease. After no paresthesia and muscle contracture at 50 Hz, 1 volt and 2 Hz, 3 volts, respectively, radiofrequency lesioning was performed for 90 sec at $80^{\circ}C$. After the procedure, both patients showed skin temperature increases greater than $2^{\circ}C$ on the affected extremity. Both patients received relief from pain and symptoms without complications. We consider that lumbar sympathectomy using radiofrequency thermocoagulation is a safe and effective procedure that can relieve pain in patients with Buerger's disease.

Epidural injection of narcotics for postoperative pain relief has been well reported. Caudal nalbuphine was assessed as a postoperative analgesic in a randomized double blind study of 80 patients after perianal surgery. Caudal block was carried out with 1.5% lidocaine 25 ml (Group 1) in 20 patients, and mixed with nalbuphine 3 mg (Group 2) in 20 patients, nalbuphine 5 mg (Group 3) in 20 patients, and nalbuphine 10 mg (Group 4) in 20 patients. Pain relief was evaluated by the subsquent need for systemic analgesics (Pethidine). In group 4, the use of systemic analgesics was significantly reduced for the first 24 hours postoperatively. Urinary retention was not correlated with nalbuphin dose.
