Hepatitis A virus infection and hepatitis A vaccination in human immunodeficiency virus-positive patients: A review

Hepatitis A virus(HAV)is one of the most common infectious etiologies of acute hepatitis worldwide.The virus is known to be transmitted fecal-orally,resulting in symptoms ranging from asymptomatic infection to fulminant hepatitis.HAV can also be transmitted through oral-anal sex.Residents from regions of low endemicity for HAV infection often remain susceptible in their adulthood.Therefore,clustered HAV infections or outbreaks of acute hepatitis A among men who have sex with men and injecting drug users have been reported in countries of low endemicity for HAV infection.The duration of HAV viremia and stool shedding of HAV may be longer in human immunodeficiency virus(HIV)-positive individuals compared to HIV-negative individuals with acute hepatitis A.Current guidelines recommend HAV vaccination for individuals with increased risks of exposure to HAV(such as from injecting drug use,oral-anal sex,travel to or residence in endemic areas,frequent clotting factor or blood transfusions)or with increased risks of fulminant disease(such as those with chronic hepatitis).The seroconversion rates following the recommended standard adult dosing schedule(2doses of HAVRIX 1440 U or VAQTA 50 U administered6-12 mo apart)are lower among HIV-positive individuals compared to HIV-negative individuals.While the response rates may be augmented by adding a booster dose at week 4 sandwiched between the first dose and the 6-mo dose,the need of booster vaccination remain less clear among HIV-positive individuals who have lost anti-HAV antibodies.

About the Nature of Ecological Ethics Debates and the Relationship between Human and Nature

There are natural ethical debates in ecological ethics, namely whether nature has intrinsic value, whether the nature has its rights. Theoretical basis of argument is the opposite of anthropocentrism and non- anthropocentrism. Ecological ethics controversy concerns the core issue of the relationship between human and nature of the ecological ethics about nature, to correctly understand and deal with the relationship between mankind and nature, ecological ethics and ecological ethics is the starting point and destination debates.

What Kind of Security Concept Does Our World Need?

While the threat of war has decreased, there have appeared intricate security issues that affect all aspects of human life, breaking through various defenses and threatening the well being of all actors in the contemporary world, including nations, groups and individuals. This risky situation calls for a new security concept, one that transcends traditional state centrism, national supremacy and coercion. The new security concept, which should assimilate the general theory of grand strategy,focuses on a vision that spans time and space, valuing humankind as it exists as one of the dynamic factors of nature and society. The essentials of the new security concept are to recognize balanced development as the substance of security and to govern national strength and the application of means and tactics. It aims at realizing comprehensive security across various social fields within states, to achieve mutual security among national, international and individual actors, as well as harmony between man and nature, continuous security leading to lasting and universal peace in the future.

Present-Day Needs of the Small Town Residents

This paper presents the results of research and analysis on the quality of the living environment in the heart of small urban centers. These cities are regarded as an attractive area of residence, among others, due to the fulfillment of human needs concerning the contact with nature （green） and living with a sense of intimacy, security and peace. Presented results concern the center of Jarostaw and Laficut. Although both cities are located in an underdeveloped region of south-eastern Poland, they have an opportunity to create a positive image of the city center, where not only attractive architectural objects can be found, but also small-town atmosphere, and natural values forming positive relationships between human and the elements of environment.

The Effects of Touch Button Size on Touchscreen Operability

The present study investigated the effects of touch button size on touchscreen operability and compared these effects between young adult and elderly participants. A total of 21 young adults （aged 22.3 ± 1.5 years） and 20 elderly adults （aged 68.1 ±4.9 years） were recruited and asked to press square number buttons （from 0 to 9） on an experimental touchscreen with their right index finger. The buttons＇ size changed during the experiment with six conditions （6, 8, 10, 12, 14 and 16 mm）. It was found that a decrease of the button size to l0 mm or below tended to increase the operation time and error rate, whereas it decreased the subjective overall operability of the touchscreen. Such effects were greater in the elderly adults than in the young adults. In addition, the reaction positions on the buttons were found to be close to the right side of them, which led the fingertip to approach the right outline of the buttons. These findings suggest that the use of small touch buttons should be minimised on touchscreens, especially for elderly users.

Sustainability： Corporate Responsibility for the Future Classroom

The machinery, equipment, inventory, and other assets of the 21 st century company without people to work them. Corporations, by leave of the accounting profession, have no real economic value continue to omit the value of human. And yet, there is a growing realization that people represent the largest proportion of corporate productive capacity relative to the current assets and fixed assets shown in corporate financial statements. This paper provides research on the top 50 of the Fortune 500 companies which confirm this material deficiency. There is a need to provide stakeholders with a ＂fair＂ knowledge of the value of corporate human capital to provide a higher standard of transparency and accountability in international financial reporting and to provide the basis for research into the sustainability and potential expansion of growth in the world economy. An appropriate standard for the valuation of human capital will provide the knowledge base for effective and efficient investment in human capital. Effective and efficient investment will be particularly valuable for governments and service industries and for those who wish to promote growth in Europe. Indeed, the Organization for Economic Cooperation and Development （OECD） is questioning the veracity of financial statements which fail to include ＂the most valuable＂ of corporate assets in their financial statements. Recently, the OECD has noted that human capital may be measurable ＂by the output potential of specific competencies＂; ＂the fruits of （corporate） investment＂; the objective measurement of the market ＂rental＂ price of human capital; and lastly, perhaps self-evident when it comes to physical capital, the output potential of corporate investment in their human capital inventory. This paper considers the conditions in the context of literature which reassesses theory and assumptions which have been made on the valuation of human capital. Human capital is a pre-requisite for tangible assets to be productive. The valuation of human capital will trigger the same sort of activity-based analysis of people power as computers brought to cost accounting. The knowledge century analysis of people power will take off when human capital is at last included in the list of assets on the corporate balance sheet.

The Animals of China in the Eighteenth-Century British Imagination

In eighteenth-century Britain, knowledge about animals from around the world was rapidly increasing. This paper focuses on what the British knew and imagined about the animals of China from reading the works of European travellers and natural historians. Whereas the animals of Africa and America served to foster a growing sense of European mastery of less civilized parts of the world through trade and possession, those of China were understood as embedded in a highly advanced civilization and therefore as sources of knowledge about that civilization. This paper examines the way in which British understandings of China were mediated through accounts of Chinese animals and of human-animal relations in China. Looking at works of popular natural history and at Oliver Goldsmith＇s fictional letters of a ＂Chinese philosopher＂ in The Citizen of the World （1762）, I argue that the animals of China bore several messages about their country. Focusing on the particular examples of the golden pheasant, the horse, the cormorant, and the cat, I suggest that British writing about Chinese animals served as a way of expressing mixed feelings about the value of advanced civilizations, whether Chinese or European.
