Obestity, characterized by an excess accumulation of fat, is a detriment to good health and wellbeing. It is easy for individuals to take on excess fat as soon as enough food and leisure are available in a society, causing an imbalance between energy intake and energy expenditure. Although there has been disagreement as to which side of this energy equation is more important in th epidemic of obesity, both sides are certainly involved. I think the prevalence of obesity begins with infancy. It seems to be relatively constant throughout childhood. Some retrospective studies have suggested that there is a direct progression from a fat chile to a fat adult. Obesity has been associated with excess mortality in many studies. The effect of obesity on cardiovascular disease has not always been an independent one, but has generally been through exacerbation of other rish factors such as hypertention, diabetes, hyperlipedmia, galbladder disease, gout and cancer of the grease and endometrium. The weights of identical twins raised in separate homes have been reported to be similar, thereby suggesting that heredity contributes significantly to weight. Overweight and obesity are by far greater health problems for many people in our society. Therefore in this paper we consider the relationship between body energy balance and problems of obesity. Whatever the weight of the person, the goal of the nutritionist and health care workers is to find solutions that will allow persons to feel better about themselves.

Piracy has been an ongoing and serious problem in international shipping industry. Somalia is often in the news these days. Somalia has been in a state of unrest for more than two centuries. In recent times, the situation has remained unstable. The persistent unrest is the major driver behind the piracy epidemic in Somalia waters. By the MIA 1906, s.78(1), the expenses in order to be recoverable must have been "properly incurred". The underwriter is also liable in certain circumstances for expenses incurred by the assured in an attempt to avert or diminish loss covered by the policy, under provisions. This class of expenditure is commonly referred to as sue and labour expenses, or suing and labouring expenses; less commonly, as particular charges. The standard marine policy(the S.G.Form) contained what was invariably called the sue and labour clause, which has been replaced in the current Institute Clauses by the "Duty of Assured(Sue and Labour)" Clause in the Hull Clauses, and the "Duty of Assured" Clause, headed "Minimizing losses", in the Cargo Clauses. Sue and labour charges are not confined to expenditure on the part of the assured and his agents, but can include quantified loss consequent upon a sacrifice properly and reasonably made to avert or minimize an insured loss.

An epidemiological survey on cholera was made toward the 291 cases admitted in Pusan National University Hospital. The results were as follows. 1. The most predominant age groups among all cholera patients were from 30 to 39(21.3%). 2. 74.9% of all cases got under the educational background of primary school and 69.4% of all cases occurred at the low income group. 3. Daily average numbers of patient were 6.2 and maximum numbers wore 15, August 19, 1970. 4. Among the food eaten prior to onset, drinking water was the most predominant with 16.2% and next, food and noodle groups were 14.8% and 10.3% respectively. 5. Regarding incubation period, it was found that 'within 48 hours' was 83.5%. 6. Patients occurred mainly in Suh Ku area with 105(36.1%) of all cases. 7. Carrier rates among family members were 1.78%. 8. Carrier rates among residents of epidemic area were 0.12%.

The recent Middle East respiratory syndrome coronavirus (MERS-CoV) outbreak has originated from a failure in the national quarantine system in the Republic of Korea as most basic role of protecting the safety and lives of its citizens. Furthermore, a number of the Korean healthcare system's weaknesses seem to have been completely exposed. The MERS-CoV outbreak can be considered a typical public health crisis in that the public was not only greatly terrorized by the actual fear of the disease, but also experienced a great impact to their daily lives, all in a short period of time. Preparedness for and an appropriate response to a public health crisis require comprehensive systematic public healthcare measures to address risks comprehensively with an all-hazards approach. Consequently, discussion regarding establishment of post-MERS-CoV improvement measures must focus on the total reform of the national quarantine system and strengthening of the public health infrastructure. In addition, the Korea Centers for Disease Control and Prevention must implement specific strategies of action including taking on the role of "control tower" in a public health emergency, training of Field Epidemic Intelligence Service officers, establishment of collaborative governance between central and local governments for infection prevention and control, strengthening the roles and capabilities of community-based public hospitals, and development of nationwide crisis communication methods.

Background: Hookah smoking has been referred to as a global tobacco epidemic by public health officials. This study aimed to investigate the characteristics, behaviour and perceptions related to hookah smoking among the youth smokers in Pune. Methods: Two hundred and eighty established hookah smokers participated in this study. Data was collected using a 29-item questionnaire, constructed using three main domains: Characteristics (socio-demographic and personal), behaviour and perceptions (about harmful effects in comparison to cigarette smoking). Results: The results indicated that the mean age of starting hookah smoking was 17.3 years; 75% of participants did not have parental acceptance; light-headedness, dizziness and headache were most common reported nicotine effects, post hookah smoking. Hookah smoking on a daily basis was reported by 24.6% participants. The mean time of hookah session was 1 hour and 19 minutes. 68.2% participants were reported to smoke hookah in hookah-cafes and 35.7% participants were found to share the hookah. Some 66.7% participants had no intention to quit. Most of them (71-80%) had misperception about the safety of hookah smoking over cigarette smoking and 54-82% participants were unaware of health effects. Conclusions: Educational intervention is urgently needed to create awareness among the youth about the harmful effects of hookah smoking.

Food is important to any animal, and a large part of the behavioral repertoire is concerned with ensuring adequate nutrition. Two main nutritional sensations, hunger and satiety, produce opposite behaviors. Hungry animals seek food, increase exploratory behavior and continue feeding once they encounter food. Satiated animals decrease exploratory behavior, take rest, and stop feeding. The signals of hunger or satiety and their effects on physiology and behavior will depend not only on the animal's current nutritional status, but also on its experience and the environment in which the animal evolved. In our novel, nutritionally rich environment, improper control of appetite contributes to diseases from anorexia to the current epidemic of obesity. Despite extraordinary recent advances, genetic contribution to appetite control is still poorly understood partly due to lack of simple genetic model systems. In this review, we will discuss current understanding of molecular and cellular mechanisms by which animals regulate food intake depending on their nutritional status. Then, focusing on relatively less known muscarinic and cGMP signals, we will discuss how the molecular and behavioral aspects of hunger and satiety are conserved in a simple invertebrate model system, Caenorhabditis elegans so as for us to use it to understand the genetics of appetite control.

21th century is a era of new pandemic. We are facing a new challenge and need a new way of approach. But eastern medicine and western medicine is clinging to their own way and have no intention to hear other one's opinion. Before the invention of the vaccination, smallpox has always been a major problem. Intellectuals in every country tried their best to find the treatment for the smallpox, and for Europian, didn't hesitate to borrow some knowledge of the pagon. Romans adopted the Galens concept, running away from the epidemic lesion. Christianity made smallpox Saints, and later adopted Razes heat therapy. But in the 17th century, these methods didn't turn out well, so they needed a new way of approach. By this movement, they had adopted the Chinese inoculation concept and invented a vaccination, By studying the effort of the Europian intellectuals who had tried their best to find the treatment for the smallpox until 17th century, we might get a glimps of wisdom which they had shown us. By this paper we can feel the passion to learn new techniques and their open mind and courage, which might be also needed in the 21th century, era of new pandemic.

This paper considers mobility control to improve packet delivery in delay-tolerant networks (DTNs) under group mobility. Based on the group structure in group mobility, we propose two mobility control techniques; group formation enforcement and group purposeful movement. Both techniques can be used to increase the contact opportunities between groups by extending the group's reachability. In addition, they can be easily integrated into some existing DTN routing schemes under group mobility to effectively expedite the packet delivery. This paper is divided into 2 parts. First, we study how our proposed mobility control schemes reduce the packet delivery delay in DTNs by integrating them into one simple routing scheme called group-epidemic routing (G-ER). For each scheme, we analytically derive the cumulative density function of the packet delivery delay to show how it can effectively reduce the packet delivery delay. Then, based on our second proposed technique, the group purposeful movement, we design a new DTN routing scheme, called purposeful movement assisted routing (PMAR), to further reduce the packet delay. Extensive simulations in NS2 have been conducted to show the significant improvement of PMAR over G-ER under different practical network conditions.

The year of 2003 was characterized as a cool humid year. Low temperature and frequent rains were continued during March to July, resulting in 1.6 times higher rainfalls and 32％ less sunshine period compared to the average yean Due to 2003's climatic condition, rice blast, and bacterial leaf blight occurred severely. Higher rainfalls caused severe epidemic of phytophthora disease and, in case of red-pepper, 55％ of cultivation acreage was devastated by the disease over the country. Besides, crop diseases which become severe under cool-humid conditions, such as gray mold, sclerotinia rot, downy mildew, increased significantly compared to the previous year. In fruit trees, brown spot of apple, and pear scab occurred severely causing much yield loss.
