Purpose: This study was conducted to examine and compare clinical manifestations and predicting factors for treatment-seeking delay among patients <65 and ${\geq}65\;yr$ with first-time acute coronary syndrome (ACS). Methods: A total of 288 patients who were diagnosed with ACS were individually interviewed at C university hospital in G-city from November 2007 to December 2008. Results: Median pre-hospital delays for younger and older patients were 5 and 12 hr, respectively. Younger patients were more likely to be current smokers, heavy drinkers, obese, stressed, and have an unhealthy diet and family history, and to complain of chest pain, left shoulder and arm pain, perspiration, and nausea. Older patients were more likely to have hypertension and diabetes, and to complain syncope and dyspnea. Logistic regression analyses showed that after adjustment for age, gender and education, progressive onset of symptom and no attribution to cardiac problem significantly predicted pre-hospital delay >3 hr in both younger and older patients. Low perceived health status was a significant independent predictor in older patients only. Conclusion: Health care providers should be concerned with different manifestations between younger and older adults, and educate people at risk for heart attack about symptoms and actions to get immediate help.

The characteristics of blood flow and the interaction between the blood vessel and blood flow play important roles in plaque cap rupture and the growth of atherosclerosis which may lead directly to a heart attack or a stroke. In this study, carotid arteries with different stenoses have been numerically simulated to investigate the wall shear stress(WSS) and the elastic motion of the vessel. Blood flow has been treated as physiological, laminar and incompressible flow. To model the shear thining behavior of the blood, the Carreau-Yasuda model has been employed but the viscoelasticity of blood has not been considered. The results show that the WSS of $severe(75\%)$ stenosis is much higher than those of $25\%\;and\;50\%$ stenosis in the region of stenosis. With the increase in the stenosis thickness, the expansion ratio of the center of the stenosis decreases while the expansion ratio of the upstream region of the stenosis increases.

Recently, in the U-health area, there are research related on monitoring brainwaves in real-time for coping with emergent situations like the fatigue driving, cerebral infarction or the heart attack of not only the patients but also the normal elderly folks by transmitting of the EEG(Electroencephalograph). This system could be applied to hospitals or sanatoriums. In this paper, it is applied for the vehicular ad-hoc network to prevent the car accident in advance by monitoring the brainwaves of a driver in real-time. In order to do this, I used mobile ad-hoc nodes supported in the Opnet simulator for the efficient EEG brainwave transmission in the VANET environment. The vehicular ad-hoc networks transmitting the brainwaves to the nearest road-side unit are designed and simulated to draw an efficient and proper vehicular ad-hoc network environment.

Background: Knowledge and individual perceptions about adverse effects of all forms of tobacco exert direct influence on the level of tobacco consumption in various socio-demographic groups. The objective of this study was to determine the nature, extent and demographic correlates of knowledge, attitudes and perceptions of use of tobacco among adults in low and middle income countries. Materials and Methods: The Global Adult Tobacco Survey, conducted in fourteen different countries from 2008-2010, was sourced for the data analyzed in this study. Descriptive statistical analyses were conducted to determine the prevalent knowledge and individual perceptions amongst adults about all forms of tobacco consumption. Results: There was relatively high awareness about the harmful effects of smoking tobacco with main awareness being about its relationship with lung cancer (>90% in most countries). In contrast, there was relatively low awareness about harmful effects of smokeless tobacco (< 90% in all countries except India and Bangladesh), and observed correlation of smoking tobacco with heart attack (40.6% in China, 65.1% in India) and stroke (28.2% in China, 50.5% in India). Conclusions: A large proportion of adults living in low and middle income countries possess adequate knowledge about smoking tobacco but have inadequate awareness as well as false perceptions about smokeless forms of tobacco. Popular beliefs of inverse relationships of tobacco consumption with knowledge, attitudes and perception of populations towards tobacco are challenged by the findings of this study.

The objective of this study was to assess beliefs (e.g. advantages, disadvantages, benefits, barriers) and knowledge about eating peanuts and tree nuts. Personal interviews based on the Theory of Planned Behavior were conducted to elicit beliefs about eating nuts. Then, a cross-sectional survey was administered to WIC participants from one county in North Carolina. One-hundred-twenty-four WIC participants (mean (SD) age=28.39 (8.09) completed the study. Most were Caucasian (51.6%) females (96%). About one third believed that eating nuts may help to lower cholesterol level. However, only about one forth believed that nuts can lower a risk of a heart attack or diabetes. More than one third believed that eating nuts will cause weight gain. The knowledge of respondents' about nutrient content of nuts was low with correct answers to most questions about 20% or below. The mean (SD) positive attitude, negative attitude, benefits and barriers scores, based on a range from 1 to 5, were 2.53 (0.91), 3.25 (0.89), 2.97 (0.85) and 2.90 (0.76), respectively. WIC participants' beliefs regarding the health effects of nuts are inconsistent with the most recent research findings. They are in a need to education about benefits of eating nuts.

If one can say that 'Retro' is a revived mode of the style, which was popular in the past, it is confirmed that various complex social and cultural factors have been reflected to making the current and new mode by accepting the past style. By investigating the impact of hippie style, which was popular during the Vietnam War on cosmetics and beauty culture, and the retro-tendency NEO-Hippie style fashion phenomenon appeared at around the time of the US and Iraq War, a theoretical foundation of cosmetics and beauty culture in the 2000s was established, and periodical circulation of fashion was tried to be understood. The 9.11 terrorists' attack and US-Iraq War devastated the heart of modern people, and for this, a retro trend having a meaning to revive the past style with nostalgia of the old things started to be handled with major interests in cosmetics and beauty culture. The retro-style, which is revived in the 2000s, is not the unchanging imitation mode in the '60s and '70s during the Vietnam War, but a newly transformed type of style.

Since the introduction of percutaneous; transluminal coronary angioplasty[PTCA] by Grunt-zig in 1977, this is widely used in some patients with coronary artery disease and is an effective alternative to surgery for many patients. Indications for emergency coronary artery bypass graft[CABG] after PTCA are prolonged chest pain, worsening of coronary artery obstruction, "current of injury" by electrocardiogram, cardiogenic shock, and in a lesser incidence, ventricular fibrillation, coronary artery dissection[without obstruction], heart block, and intractable cardiac arrest. Recently, we have experienced one case of emergency CABG following unsuccessful PTCA. The patient was 54 year-old male and admitted with complaint of angina pectoris. The routine electrocardiogram revealed within normal limit. The treadmill test revealed severe chest pain after 2 min. exercise. Coronary cineangiogram revealed 95% segmental stenosis of the proximal right coronary artery. Our cardiologist was planned PTCA. During PTCA, severe chest pain and ischemic pattern on electrocardiogram were developed. But they were not relieved even by morphine and nitroglycerin till 90 min. So we performed emergency single coronary artery bypass graft from aorta to proximal right coronary artery with great saphenous vein. The patient had an excellent postoperative recovery and was free from anginal attack. He has shown striking improvement in general status[NYHA functional class 1] during 6 months after operation.operation.

From the reference research, the results obtained were as follows. 1. Until the "Song" dynasty, the predominant cause of facial nerve paralysis was the attack of Pathogenic Wind to "the Stomach Channel of Foot Yangming, (St.C.); and "the Small Intestine Channel of Hand Taiyang, (S.I.C.). They recognized the facial paralysis as an aspect of palsy. 2. In the period of Jin-Yuan(金元), the predominant cause was described as "Xuexu"(the deficiency of blood) and phlegm. They recognized that the facial palsy was a palsy. However, they also acceded to the possibility that there could be other explanations. 3. In the period of "Ming & Qing", there were numerous kinds of causes. For example, the following were identified as attacking the Meridian: the Pathogenic Cold; Pathogenic Heat; "Xinxu"(the deficiency in the heart); Fire and Heat combined as a pathogenic factor; "Pixu"(the deficiency in the spleen); and, "Xinxu"(the deficiency of blood). 4. In the past, Koreans have explained the facial paralysis according to the Chinese theories mentioned. However, recently there has been an emergence of another Chinese theory; whereby, facial paralysis is classified into causes and symptoms, and then medical treatment is applied accordingly. 5. From the occident medical perspective, the facial paralysis is categorized into two causes. The first is called central facial nerve paralysis and the second is called peripheral facial nerve paralysis. The latter is mainly caused by Bell's palsy, Herpez zoster oticus, and trauma.

1. According to causes of attack and symptoms, tinnitus is divided into two categories; deficiency and excess. Causes of excess syndrome of tinnitus were wind fire in the liver and gallbladder, phlegm fire, blood stagnation, and heat in meridian system and the causes of deficiency syndrome of tinnitus were qi deficiency or blood deficiency after an illness or delivery, yin deficiency of liver and kidney, and deficiency of sea of the marrow. 2. Tinnitus was related to the vicera and bowels, especially to liver, gallbladder and urinary bladder. 3. In regard of method of treatment, tonify kidney, nourish heart, clear the liver and discharge heat are used according to visera and bowel theory. Clear phlegm and downbear fire are used for phlegm fire. Tonify spleen and kidney is used for ancestral vessel deficiency. Dispel wind and dissipate fire can be used according to theory of five elements' motion and six kinds of natural factors. 4. The basal meridian of acupuncture and moxibustion treatment were the channels of Shaoyang.. 5. Regarding neuropsychiatric aspect of tinnitus, sudden anger and depression of mind were the main mechanism of disease and liver fire was the main cause. The prescriptions for neuropsychiatric tinnitus were Dangguiyonghuehwan, and Yongdamsagantang.
