      • Ecological changes affecting vector-borne diseases in Korea

        Terry A. Klein,Heung Chul Kim 한국응용곤충학회 2009 한국응용곤충학회 학술대회논문집 Vol.2009 No.10

        Ecological changes, both man-made and natural, have changed the landscape of the Republic of Korea following the end of Japanese occupation at the end of World War II (1939-1945). During the Japanese occupation, forested hillsides were cleared and wood products shipped to Japan, leaving the hills and mountains largely covered by grasses and other shrub vegetation. Following WWII, the country of Korea was divided into North and South Koreas, with North Korea under communist powers, while South Korea was established as a democratic government. In South Korea poverty was rampant and local populations scavenged for wood for cooking and heating during the cold winters. Just as economic conditions were increasing, South Korea was attached by North Korea, beginning a long drawn-out conflict from 1950 to the summer of 1953, whereby an armistice was signed and an often uneasy peace between the two countries continues today. Again, the Republic of Korea emerged from a War as an impoverished country with treeless country sides, hills, and mountains. In the 1960’s, president Chung-Hee Park established a tree planting policy to reestablish long-ago lavish forested mountains and hillsides that make up more than 70% of the South Korean landscape. Today, mountains and hillsides are generally not used for agriculture and are completely forested, with planted groves and volunteer trees ranging in age from 10-50 years. These forested areas have led to increased protection for large and small mammals and birds, increasing the potential for zoonotic pathogens that there ectoparasites harbor to be transmitted to man during work and leisure activities. While forested areas provided an expanded habitat for some animals, agriculture expanded and modernized, resulting in short-cut grasses on banks separating much of the rice paddies, orchards, ditches, and dry-land farming that increased competition for small mammal habitat. As a result of increased surveillance of small and large animals and their ectoparasites, the increased prevalence of known pathogens and identification of new pathogens, especially those harbored by ticks, has demonstrated the presence of tick-borne encephalitis, several species of spotted fever group Rickettsia, and a host of other zoonotic diseases in wild animals, their ectoparasites, and man. As tick-borne diseases are not reportable diseases in Korea, the extent and impact on civilian and military populations is unknown as diagnoses are often likely sought for the wrong pathogen. While agriculture modernized, military training sites largely consist of unmanaged lands with tall grasses that are conducive to large and small mammal populations, which are host to a number of zoonotic diseases, e.g., hantaviruses, scrub typhus, murine typhus, leptospirosis, tick-borne encephalitis, spotted fever group rickettsial pathogens, Lyme disease, bartonellosis, etc. that impact on military populations training in those areas. The impact of training sites habitat modification has not been assessed, but for many sites is impractical. To reduce health risks of vectorborne diseases, the US Army has established better housing (tents to barracks with screened windows and air conditioning) at some field training sites, reducing the potential for the transmission of mosquito-borne pathogens (malaria and Japanese encephalitis virus). The increased use of permethrin-treated all climate uniforms (ACUs) and repellents, also reduce the potential for transmission of mosquito-, tick-, mite-, and flea-borne pathogens. However, training conditions at some field training sites remain largely unchanged, with personnel working and sleeping in tents that abut to forested areas where animals and their ectoparasites are present. While some training and maneuver sites are well planned for weapons qualifications of wheeled and tracked vehicles, others sites are in areas of unmanaged lands which are rodent infested. Increased surveillance by the 65th Medical Brigade not only provides a baseline and relative distribution for vector-borne diseases in Korea, but also provides disease trends and risk assessments that are necessary for protecting US military personnel training in Korea.

        Green Tea Polyphenols Extend the Lifespan of Male Drosophila melanogaster While Impairing Reproductive Fitness

        Terry Lopez,Samuel E. Schriner,Michael Okoro,David Lu,Beatrice T. Chiang,Jocelyn Huey,Mahtab Jafari 한국식품영양과학회 2014 Journal of medicinal food Vol.17 No.12

        Green tea is a popular beverage believed to have many health benefits, including a reduction in the risks of heart disease and cancer. Rich in polyphenolic compounds known as catechins, green tea and its components have been shown to increase the lifespan of various animal models, including Drosophila melanogaster. Here, we investigated the genderspecific effects of green tea on the lifespan of fruit flies and observed that green tea extended the lifespan of male flies only. This effect was found to be independent of typical aging interventions, such as dietary restriction, modulation of oxidative energy metabolism, and improved tolerance to environmental stresses. The one exception was that green tea did protect male flies against iron toxicity. Since there is an inverse correlation between lifespan and reproduction, the impact of green tea on male reproductive fitness was also investigated. We found that green tea negatively impacted male fertility as shown by a reduced number of offspring produced and increased mating latency. We further identified that the lifespan extension properties of green tea was only observed in the presence of females which alludes to a reproductive (or mating) dependent mechanism. Our findings suggest that green tea extends the lifespan of male flies by inhibiting reproductive potential, possibly by limiting iron uptake. To our knowledge, our study is the first to report the negative impact of green tea on Drosophila male reproduction. Our results also support previous studies that suggest that green tea might have a negative effect on reproductive fitness in humans.

        Making Culture Into Magic: How Can It Bring Tourists and Residents?

        Terry Nichols Clark 한국행정학회 2007 International Review of Public Administration Vol.12 No.1

        I Globalization encourages a New Political Culture (NPC), stressing individualism and egalitarianism, and new modes of governance and public adminstrationII. Consumption and amenities rise in salience to individual citizens and political leaders--with more income, education, and the NPC. Culture and tourism are key parts of this transformation. III. What makes culture magical? Scenes. Culture comes packaged with more: buildings, restaurants, and an audience; a performance can resonate only if it connects to values and concerns of the audience. We sketch 12 types of scenes like Disney Heaven and Bohemia, then 15 dimensions for interpreting like traditionalism, egalitarianism, etc. IV. How to make culture magical? By constructing integrated components of culture and tourism. How? Collect data on many dimensions of consumption (restaurants, types of nearby shops, crime rates, and more). Codify these into types like Disney Heaven or Bohemia. Then calibrate attractive powers of each type of scene and dimension for different types of tourists or residents. To implement this program, we have developed a large data base of 40,000 US zip codes and are working with others internationally along parallel lines (in France, Italy, Britain, Germany, Japan, and Korea). This policy-linked analysis tool is more powerful than most past tourism and culture studies.

        Strategies for Brand Protection, -Korean Anti-Counterfeit Laws and Measures-

        ( Terry Kim ) 건국대학교 법학연구소 2017 一鑑法學 Vol.0 No.37

        “당신이 그것을 만들 수 있다면, 당신은 그것을 위조 할 수 있다.” 거의 모든 제품은 위조 될 수 있고 위조되어 왔다. 오늘날, 모조품 문제는 세계 무역의 7%를 차지하는 국제적인 병폐가 되었다. 많은 이해 관계자들의 지속적인 노력에도 불구하고 위조 상품의 문제는 보다 기발하고도 애매한 수단을 통해 계속 줄어들지 않고 있다. 그러나 위조는 방지 될 수 있다. 지식 재산권의 관점을 통해 위조 문제에 접근함으로써, 이 논문은 한국에서 위조에 대응하기 위해 가능한 민사, 형사 및 통관 대책과 정부의 발의를 설명한다. “If you can make it, you can fake it.” Almost any product can be and has been counterfeited. Today, the problem of counterfeit goods has become a global epidemic that accounts for as much as seven percent of global trade. Despite sustained efforts by many stakeholders, the problem of counterfeit goods continues to grow unabated through more creative and elusive means. However, it is possible to defend against counterfeiting. By approaching the problem of counterfeiting through the lens of intellectual property rights, this Article will describe the civil, criminal, and border measures that are available and the government initiatives that are in place to fight counterfeiting in Korea.

        Stellar Archeology: What White Dwarf Stars Tell Us About the History of the Galaxy

        Terry D. Oswalt 한국우주과학회 2012 Journal of Astronomy and Space Sciences Vol.29 No.2

        White dwarf stars have played important roles in rather diverse areas of astrophysics. This paper outlines how these stellar remnants, especially those in widely separated “fragile” binaries, have provided unique leverage on difficult astrophysical problems such as the ages of stars, the structure and evolution of the Galaxy, the nature of dark matter and even the discovery of dark energy.

        Identity work of welfare service users in participatory spaces

        Terry Tse Fong Leung 한국사회복지학회 2018 Asian Social Work and Policy Review Vol.12 No.1

        The popularizing user participation agenda has encouraged the creation of discursive spaces for collaborative decision-making with the welfare service users. Despite the claim of partnership with the service users, these participative spaces do not always promise parity of participation. Based on a qualitative study conducted in Hong Kong, this paper discusses the manifestation and constitution of identity among the welfare service users who took part in organizational spaces for participatory management. The analysis uncovers the tensions and promises in participatory management with the welfare service users
