Background: This study is aimed at describing the outcomes of the management of the patients, caregivers, and healthcare workers (HCWs) who are exposed to the pandemic influenza (H1N1 2009) virus and at evaluating the adequacy in exposure management and infection control. Methods: From July 2009 to January 2010, for 7 a month period, we managed patients and healthcare workers without any respiratory protective devices, who came within 1 m distance of H1N1-positive individuals for more than 1h and performed a 1-week follow-up. Results: The total of 157 cases with exposure to pandemic influenza (H1N1 2009) virus and exposed individuals of 907 were reported. Of the exposed individuals who were under management, 15 were confirmed to be infected with the infection rate being 1.7%. The confirmed individuals did not have a secondary infection after the exposure. Rates of infection of the exposed patients and healthcare workers were 1.8% and 1.6%, respectively, and these figures were not statistically significant. Conclusion: The exposure management results at the hospital revealed that the infection had spread by contact with individuals who were positive for the infection. The high incidence of early exposure to the virus warrants the need to ensure the use of protective equipment and the adoption of assertive teaching methods that have long lasting effects.

PTR-TOF-MS를 활용한 돈사악취 모니터링 연구

The annual number of odor complaints increased about 10 times over 14 years from 4,302 in 2005 to 40,854 in 2019, in Korea. Especially, livestock facilities account for more than 50% of the odor complaints and the swine farms account for the most odor complaints among livestock. It is therefore necessary to manage swine farms as the major odor emission source. In this study, a real-time odor monitoring system equipped with PTR-TOF-MS (proton transfer reaction time-of-flight mass spectrometric) was used to measure the odorous substances in two swine farms. Odorous substances emitted from outlets were sampled and measured at the two types of swine farms. In addition, the boundary spots were designated as measurement points. As a result, the rankings of the odorous substances in order, from highest to lowest, were ammonia, acetaldehyde, methyl mercaptan, fatty acids, etc. and the level of odor intensity was 0.8-4.4 at the outlet of the swine farms. The concentration at the boundary decreased between 1/100 ~ 1/10000 compared to the concentration emitted from outlets. Base on the results of evaluating odor activity values, Skatole and p-Cresol were estimated as major odor substances in swine farms. .

Recently, as the personal computers are supplied rapidly, they formed the nucleus of the computer system. But, because of the easiness that anyone uses them to go near easily, it is the fact that the security of personal computer is weakness. So, in the paper, we propose the technical method that minimizes the loss and leakage of important data. This paper implemented a cryptosystem for security of data file on personal computer and assistance storage medium. The way of encryption/decryption is applied by complexity method which mixed a typical RC4(Rivest Cipher version 4) algorithm of stream cipher and a typical MD5(Message Digest version 5) of HASH Function. For valuation implemented cryptosystem, three criteria is presented, which are crypto complexity, processing time and pattern matching. And according to analysis the three criteria, the cryptosystem is verified the security, efficiency and usefulness. The cryptosystem is programmed with Visual C++ language of Microsoft. And so, as this is software system, we shall have a technical security system at a minimum cost for all personal computer.

미국학과 미국경제

The United States is a country, which has become close to us despite the short history of contact between the two countries. Especially during the latter half of 20th century one may go so far as to say that we have lived in a framework made by America politically, economically, militarily and culturally. In this respect the necessity of research and education in American Studies is self-evident. The purpose of studying the American economy includes to learn from the American experience, to be successful in trading with the states and to be a successful investor in the states. The first lesson we need to learn from the American economy is that the success and dynamism of the American economy is from its free market economy which it has had since the beginning of the country. Sometimes it went through recession and even a great depression but it overcame those problems and now stands as the biggest and strongest economy in the world. Sometimes it faced challenges from reformists, who argued for renovation to solve problems such as the aggravating income disparity and the corruption of bureaucrats linked to industrialists. Sometimes it faced the challenge of socialists, who tried to capsize the economic system. It survived all those challenges and stands as a bulwark of the prosperous capitalism. During the 50 year period from 1930 to 1980, however, America has seen the expansion of government interferece and the welfare system, which has caused a slowdown in productivity. Since 1980, however, the Reagan administration has revived the tradition of the market economy, which can be characterized as deregulation, low tax rate and reduced welfare programs. These changes in the 1980's prepared the groundwork for the American economy to prosper in late 1990's, which is often dubbed the "New Economy." This is different from many Korean's idea that the American economy is a mixed economy with heavy government interference. In other words, Koreans are generally more familiar with the liberal aspects more attention should be given to the conservative aspects. It is because the success of the American economy is more due to the market economy than to government interference. In order to understand America as a trading partner or as a target of foreign investment, sveral other relevant subjects such as American government, social structure, thought and literature, law, geography, and agronomy should be studied. As American studies is a multidisciplinary subject, it requires a multidisciplinary approach to study the American economy.

경구 및 흡입에 의한 탄화수소(휘발유) 중독 2예

Hydrocarbon poisoning is one of the most common poisonings accounting for about 3% of all poisonings in the USA. Hydrocarbons are a broad group of organic compounds consisting of hydrogen and carbon atoms. Many household products contain hydrocarbons. The primary complication of hydrocarbon poisoning results from involvement of the respiratory and the central nervous systems. Other reported complications include cardiac arrthymia, hepatocellular damage, renal failure, peripheral neuropathy, intravascular hemolysis, cutaneous injury, sudden death, and so on. We experienced two cases of acute poisoning caused by hydrocarbons: one was a 64-year-old man with cardiac arrhythmia after ingestion of gasoline and the other was a 61-year-old man with aspiration pneumonia after inhalation of combustion gas of gasoline. We report these cases and present a literature review.
