  • Objectives: To validate a critical-size mandibular bone defect model in miniature pigs. Materials and Methods: Bilateral notch defects were produced in the mandible of dentally mature miniature pigs. The right mandibular defect remained untreated while the left defect received an autograft. Bone healing was evaluated by computed tomography (CT) at 4 and 16 weeks, and by micro-CT and non-decalcified histology at 16 weeks. Results: In both the untreated and autograft treated groups, mineralized tissue volume was reduced significantly at 4 weeks post-surgery, but was comparable to the pre-surgery levels after 16 weeks. After 16 weeks, CT analysis indicated that significantly greater bone was regenerated in the autograft treated defect than in the untreated defect (P=0.013). Regardless of the treatment, the cortical bone was superior to the defect remodeled over 16 weeks to compensate for the notch defect. Conclusion: The presence of considerable bone healing in both treated and untreated groups suggests that this model is inadequate as a critical-size defect. Despite healing and adaptation, the original bone geometry and quality of the pre-injured mandible was not obtained. On the other hand, this model is justified for evaluating accelerated healing and mitigating the bone remodeling response, which are both important considerations for dental implant restorations.

  • The purpose of this study was to review health and adjustment issues of Korean students in the context of international students' health in the United States. The number of international students studying in the United States has increased. In addition, more and more Koreans come to the United States for education. Korean students formed the fifth largest international group found on American campuses. As more and more international students study on American campuses, their health needs and problems became a concern to health professionals. Most health problems international students experience are stress related and psychosomatic. These students also have difficulties in using health care services. International students face barriers to obtaining health care because of differences in language and differences in cultural beliefs toward health. Korea manifests an eastern culture which is quite different from the western culture, so many Korean students studying in the United States experience difficulties in adjustment and using health care services. The study on the needs of Korean students in the U.S. reviewed in this research was a survey of 105 Korean students at the Pennsylvania State University, 1990. Korean students' health problems included stress, colds, fatigue, and headaches. Homesickness, financial problems, and academic problems were also important problems the Korean students faced. Korean students usually did not participate in any activities with Americans as much as with Koreans. Most Korean students did not participated in any health education workshops held on campus. This may be because the students had not participated previously in health education workshops conducted on campuses in Korea. Korean student's confidence with the English language appeared to be an important variable in using or not using the university health services. University health professionals in the United States need to develop better information system for international students so that they may better use the health services provided on campus. Also, university health professionals working on campuses in Korea need to put more attention on health of college students and provide on-campus health education workshops which meet the student's needs.

  • The United States has been known as the world's major producer of crops such as wheat, corn, and soybeans. Therefore, using meteorological long-term forecast data to project reliable crop yields in the United States is important for planning domestic food policies. The current study is part of an effort to improve the seasonal predictability of regional-scale precipitation across the United States for estimating crop production in the country. For the purpose, a dynamic downscaling method using Weather Research and Forecasting (WRF) model is utilized. The WRF simulation covers the crop-growing period (March to October) during 2000-2020. The initial and lateral boundary conditions of WRF are derived from the Pusan National University Coupled General Circulation Model (PNU CGCM), a participant model of Asia-Pacific Economic Cooperation Climate Center (APCC) Long-Term Multi-Model Ensemble Prediction System. For bias correction of downscaled daily precipitation, empirical quantile mapping (EQM) is applied. The downscaled data set without and with correction are called WRF_UC and WRF_C, respectively. In terms of mean precipitation, the EQM effectively reduces the wet biases over most of the United States and improves the spatial correlation coefficient with observation. The daily precipitation of WRF_C shows the better performance in terms of frequency and extreme precipitation intensity compared to WRF_UC. In addition, WRF_C shows a more reasonable performance in predicting drought frequency according to intensity than WRF_UC.

  • This study examined social integration policies for multi-cultural families in Korea and the United States through a literature review and internet research. Because the United States has developed and maintained its own culture, this was an appropriate country to compare to Korea in terms of social integration policy. There were four main results. First, both countries enforce assimilation policies for multi-cultural families. Second, most social integration programs and services for multi-cultural families in Korea are carried out by the Multi-cultural Family Support Centers, which are supported by the national and local governments in Korea. However, because the U.S. government has preserved a laissez-faire approach to policies for immigrant families, there are no government-based support centers for multi-cultural families in the United States. Third, both countries focus on the assimilation of multi-cultural families. Nevertheless, the U.S. government promotes a balance between ethnic identity and U.S. citizenship. Fourth, the U.S. government strongly supports second-generation education and development programs that recognize the second generation as a human resource for the future of society. In summary, even though there were some cultural differences between the two countries, the United States' assimilation policies based on ethnic identity would be useful for Korean integration policies. In addition, it is very important to offer opportunities for mutual integration in everyday life between Korean families and multi-cultural families.

  • The purpose of this study is to provide useful insights into community-level support services for family caregivers in Korea by comparing them with the services in the United States. Similar to most developed countries, life expectancy has led to rapid population aging in Korea over the last several decades. However, despite increased social needs of long-term care for the elderly, many elderly Koreans are still dependent on their family for the long-term care. Yet, existing support programs for family caregivers are very limited. As a result, family caregivers often suffer from a lack of financial resources and emotional support. In this study, we comprehensively review the extensive literature, including relevant studies and documents of community-level support services for family caregivers of the elderly at home in Korea and the United States. One of the most important differences is that compared to Korea, diverse services based on the law of NFCSP to support the family caregivers, such as counseling, organization of support group, and educating have been available in the United States since 2000. Additionally, the legal definition of family caregivers in the United State is broader than that in Korea, where family caregivers are limited to those who are related by blood or marriage. Therefore, more caregivers are eligible for support programs and benefit from the programs in the United States. The findings of the study suggest that policy makers in Korea should legislate for diverse and comprehensive services for family caregivers. Further, it is necessary to define legal terms for family caregivers more broadly to extend beneficiaries of the programs.

  • 1994년의 UN 해양법 협약과 1996년의 배타적 경제수역(EEZ)에 의해 해양관할권이 확대되면서 인접국가와의 배타적 경제수역과 어업협정과 같은 여러 가지 문제가 발생하고 있으며 중국선박의 불법조업으로 인한 피해가 끊임없이 발생하고 있다. 또한, 삼면이 바다로 둘러싸인 우리나라는 해양관광과 해양레저를 이용하는 관광객이 증가하여 해양환경과 안전관리에 대한 목소리가 높이지고 있다. 최근 몇 년 국가안보와 직접적으로 관련 있는 천안함 침몰과 연평도 포격사건 등 해상안전에 대한 불안감도 높아지고 있다. 이렇게 급변하는 해양환경 속에서 우리나라 해양경찰은 끊임없는 변화와 발전을 거듭하고 있으나 불안감은 쉽게 해소되고 있지 않고 있다. 우리나라와 마찬가지로 삼면이 바다로 둘러싸여있는 미국 역시 해양관련 업무가 매우 중요한 국가사 중 하나로 자리 잡고 있다. 1790년에 창설된 미국 해안경비대 (U. S. Coast Guard: USCG)는 미국 국토안보부(The Department of Homeland Security) 산하로 자국 영해/영토 방어와 해안경비 및 구난을 목적으로 하지만 우리나라의 해양경찰과는 달리 군사조직으로 분류되어 실전에도 참가하기 때문에 그 임무수행의 영역과 무력행사 기준 및 대상에 있어 우리나라 해양경찰과 차이점을 보인다. 본 연구에서는 미국 내에서 가장 오래된 정부 기관 중에 하나인 미국 해안경비대(USCG)를 소개하는 것을 목적으로 하며 미국 해양경비대의 역할과 기능을 소개하고 중요성을 논의 하였다. 향후 해양환경의 변화에 따른 우리나라의 해양주권수호와 해양안전을 책임지는 해양경찰 조직의 발전방안에 기여하기를 기대한다.

  • This essay examines Edward Said's Culture and Imperialism focusing on the concepts of 'culture,' 'empire,' and 'nation'. The approach is critical, theoretical, and historical rather than explicatory. Consequently, the range of the essay is not limited to Said's own explanation and argument about Western imperialism and its culture presented in the book. In doing this, this essay finally purposes to be a discursive resistance to the current global empire, the United States, via a critical reading of Said's work. Said's notion of culture is set upon to disclose the function of culture as an apparatus of ideological consent of the dominated to the dominant. When applied to imperial practice, Western culture functions to subject the colonized to the colonizer. Said's geographical approach to imperialism complements the historical understanding of imperialism. Imperialism is not only the practice of Western-centered historicism but also the spatially mutual interaction between the West and the rest of the world. Along with European imperialism, Said poses the current global empire of the United States as his main target of criticism. Said's problem is that he takes the United States as a nation-state. When examined, the United States is not a nation-state, but today's empire. The empire in the appearance of the nation-state United States does not work for the interest of the American nation, that is, the American people. The empire is the transnational and postnational political and economic institution that works for the interest of global capital. In order to resist the current global empire, this essay suggests that the building or restoration of nation-states with its basic principle of people's sovereignty is in need.

  • Purpose: The purpose of the study was to compare level of functional independence and its correlates among community-dwelling older adults in rural areas between South Korea and the United Sates. Methods: The study employed a comparative and correlational design. Data were collected from 198 community-dwelling older adults in rural areas (South Korea=100, & US = 98). Functional independence, cognitive function, obesity and general characteristics were measured. Results: From both countries, approximately fifteen percent of older adults living independently had cognitive problems without any treatments. Among Korean older adults functional independence was associated with a number of chronic diseases and aging while in the United States the participants had a negative correlation with obesity and aging. Conclusion: For Korean older adults in rural areas, nurses should focus on monitoring older adults' abilities to manage chronic illness and designing self-management programs while in the United States the focus should be on healthy lifestyle programs about exercise and diet to increase functional independence.
