A complex event processing system, becoming useful in real life domains, efficiently processes stream of continuous events like sensor data from IoT systems. However, those systems do not work well on some types of queries yet, so that programmers should be careful about that. For instance, they do not sufficiently provide detailed guide to choose efficient queries among the almost same meaning queries. In this paper, we propose an query preprocessing tool for event stream processing systems, which helps programmers by giving them the hints to improve performance whenever their queries fall in any possible bad formats in the performance sense. We expect that our proposed module would be a big help to increases productivity of writing programs where debugging, testing, and performance tuning are not straightforward.

In this paper, we measured human body signals in order to verify a active harness system that we developed for gait and balance training. The experimental procedure was validated by tests with 20 healthy male subjects. They conducted motions of Activities of Daily Living(ADL)(Normal Walking, Stand-to-Sit, Sit-to-Stand, Stair Walking Up, and Stair Walking Down) according to body weight support rates (0%, 30%, 50% of subjects' body weight). The effectiveness of the active harness system is verified by using the results of foot pressure distribution. In normal walking, the decrease of fore-foot pressure, lateral soleus muscle and biceps femoris muscle were remarkable. The result of stand-to-sit results motion indicated that the rear-foot pressure and tibialis anterior muscle activities exceptionally decreased according to body weight support. The stair walking down show the marked drop of fore-foot pressure and rectus femoris muscle activities. The sit-to-stand and stair walking up activities were inadequate about the effect of body weight support because the velocity of body weight support system was slower than male's activity.

Animal companionship is gaining popularity in Korea, and interest in dog walking is also increasing as a strategy to maintain the physical and mental health of dogs and dog owners. The purpose of this study was to investigate the perception and satisfaction of dog owners with the neighborhood environments for dog walking and to examine the willingness to pay (WTP) for an off-leash dog park. Of a total of 249 online survey respondents, 47.8% said they take a walk at least once a day and mainly walk around nearby neighborhoods or parks. Respondents showed a high attachment to their dogs and recognized that dog walks help increase physical activity and maintain the health of owners and their dogs. The satisfaction with neighborhood environments, such as attractive views and the connection of walking trails, was low, and there was a high demand for off-leash dog parks. The truncated mean WTP was estimated to be 85,618 Korean Won, and the result of regression analysis and t-test revealed that walking frequency and the satisfaction with dog walking facilities were statistically significant in the WTP. In order to encourage dog walking to promote physical activity and health, more attention needs to be devoted to improving neighborhood environments for dog walking.

It has been reported in animal and human studies that green tea shows a health protective characteristics. In the present study, we investigated the disease prevalence according to chronic green tea consumption in 92 subjects (mean age: 59.548.9, men: 41, women: 51) living in green tea cultivation village. The consumption of green tea and other life-style characteristics were ascertained by a questionnaire. The subjects were divided into three groups according to the period of green tea consumption (0, < 10 year, and $\geq$ 10 year). For green tea consumption groups, most of the subjects have been drinking green tea in order to protect disease and recognized the effects of green tea as detoxification of alcohol and smoking, protection of cold or release from fatigue. There were no significant differences in drinking and smoking, physical activity, and a cold prevalence among the groups. Green tea consumption was associated with lower levels of prevalence of tooth decay as well as the osteoporosis. The score of dietary habits was higher by increasing green tea consumption period (p<0.05). Consequently, chronic green tea consumption can be considerably effective in health promotion.

This study reviewed the important preceding studies of prevention and treatment of the crimes and therapies on the characteristics of mental illness, trying to investigate and identify more effective ways to prevent, decrease the crimes of the mentally ill and treat them. The main results were as follows. First, relationships between mental illness and crimes have been inconsistently reported, to investigate environmental stresses and triggers of the mentally ill additionally. Second, the term 'mentally illness' was to be defined more specifically, such as severe psychiatric disabled, antisocial personality disorder, intellectual disability, anger·impulse control disorder, and drug abuse. If medication and psychosocial treatments were properly treated to the severe psychiatric disabled, their crime incidence and recidivism will be decrease enough to live with their neighbors in community. But the ways and processes of treating antisocial personality disorder, intellectual disability, anger·impulse control disorder, and drug abuse were very different from it, requiring more intense psychological, medical and biological interventions and social seclusion. The national campaigns and projects for their human rights and community care will be needed to promote the therapeutic effects for them. The limitation and future tasks were discussed.

Hepatic diseases are divided into two types: alcoholic and non-alcoholic. Non-alcoholic liver injury finally induces fatty liver and damages liver function. Many studies have demonstrated that Ecklonia stolonifera has antioxidative, anti-inflammatory, and hepatoprotective activities. We conducted a 12-week double-blind, placebo-controlled, randomized trial to examine the efficacy of E. stolonifera extracts (ESE) on biochemical markers of hepatic function. Sixty-five subjects with mild or moderate liver injuries were randomly allocated to receive either 420 mg/d of ESE or a placebo for 12 weeks. Fifty-five participants completed the trial. No significant adverse events were observed among the subjects during the study. The primary end points were changes in plasma levels of aspartate transaminase (AST), alanine transaminase (ALT), and γ-glutamyltransferase (γ-GT). The secondary end points were changes in lipid profile levels, including total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL), and low-density lipoprotein cholesterol (LDL). Compared with the baseline, AST and ALT levels decreased significantly in the ESE group compared to those in the placebo group (P<0.001). In addition, γ-GT levels in the ESE group were significantly lower than those in the placebo group (P=0.016). There were no differences in the TC, TG, HDL, and LDL levels between groups. In conclusion, ESE consumption for 12 weeks improved liver parameters in subjects with liver injury. Regular consumption of ESE could maintain liver health in individuals at risk of hepatic damage.
