  • 현대 사회는 기술의 발전에 따라 다양한 분야에서 급격히 발전을 이루고 있으며, 자동치 또한 예외가 아니다. 또한 자동차의 수가 늘어가면서 그에 따라 문제점도 많이 발생하고 있는데, 자동차 개체수의 증가와 더불어 가장 큰 문제는 자동차 사고로 인한 재산 및 인명피해가 급격하게 증가하는 것이다. 자동차 사고 시 빈번하게 발생하고 있는 운전자의 의식불명에 따른 초기 응급조치 미흡, 뺑소니 등으로 발생하는 2차 교통사고를 방지하기 위해 블랙박스 기반의 차량용 응급상황 감지 및 통보시스템이 필요하게 되었다. 본 논문에서는 사고감지, 정보분석 및 정보운용기술을 바탕으로 기존의 블랙박스보다 차량상황 감지의 정확성을 높였으며, 현재 높은 보급률을 보이는 스마트폰을 이용한 응급상황 감지 및 통보시스템을 설계 및 구현하였다.

  • 전남 광양읍 봉강면의 양란 재배농가에서 재배되고 있는 덴파레에 검은점무늬병이 발생하였다. 자연 발병한 덴파레의 잎에는 초기에 검은색의 작은 점무늬가 형성되어 점차 진전되면서 잎 전체가 누렇게 변하면서 고사해 버리며 소엽병의 마디가 약화되어 낙엽이 지고 심하면 식물체 전체가 말라죽었다. 검은점무늬병에 감염된 덴파레의 병환부로부터 분리된 병원균은 감자한천배지 상에서 초기에 흰색을 띠며, 점차 시간이 지남에 따라 진한 보라색을 띠었으며, 균사생장 적온은 $25^{\circ}C$였다. 덴파레 잎의 검은 점무늬 병반으로부터 분리한 병원균은 균학적 특성 및 병원성 검정 결과 Fusarium moniliforme로 동정되었다. 병원균은 상처 접종에 의해서만 덴파레에 병원성을 나타내었고, 호접란과 심비디움에 대해서도 모두 병원성을 나타내었다. 따라서 이 병을 Fusarium moniliforme에 의한 덴파레 검은점무늬병으로 명명할 것을 제안한다.

  • The thermal death kinetics of the Black timber bark beetle, Xylosandrus germanus, was investigated to develop a heat treatment for control of infested wood packing materials used to export goods. To determine the feasibility of microwave irradiation as an alternative control method, laboratory experiments irradiating wooden blocks of Douglas fir ($200{\times}200{\times}250mm$), which were artificially infested with adults, with 2.45 GHz of microwave energy. All (100%) Ambrosia beetle adults were killed by both hot water treatments and microwave irradiation at $52^{\circ}C$ and $58^{\circ}C$, respectively. Probit analyses estimated the internal wood temperature required to produce Probit (0.99) efficacy to be $64.7^{\circ}C$ (95% CI $62.4-69.9^{\circ}C$) at one minute after microwave treatment.

  • Pine tree death caused by pine wood nematode(PWN) involves phoretic relationships between PWN and its vector Japanese pine sawyer beetle(JPS). In an effort to understand the diversity of fungi involved in PWN life cycle, a total of 176 fungal isolates were collected from PWNs, adults and larvae of JPS, PWN-diseased Japanese black pine that was cut down in 2005 at Jinju, Korea. Based on microscopic observation and colony morphology, and sequence analysis of the ITS rDNA, the fungal isolates were identified at the level of genus. Three genera including Mucor, Ophiostoma, and Penicillium were identified from PWN. Two genera of Ophiostoma and Penicillium were discovered from JPS larvae. Frpm JPS adult beetles, nine genera of Aspergillus, Gibberalla, Hypocrea, Irpex, Leptosphaeria, Ophiostoma, Penicillium, and Plectosphaerella and unknown basidio-mycetes were found. Ten genera from PWN-infected weed were confirmed as Bionectria, Botrytis, Camarops, Fusarium, Hypocrea, Nectria, Mucor, Ophiostoma, Penicillium, and Trichoderma. Penicillium and Ophiostoma were commonly distributed on PWN and its vector and host. This is first report of the fungi associated with PWN and its vector and host in Korea.

  • This paper focuses on "The Story of $Bras-Coup{\acute{e}}$" in George Washington Cable's The Grandissimes (1880), a story to and around which Cable claimed the larger work was built. It tells of an African candio sold into slavery who, to the dismay of his white purchasers, refuses to work, strikes his master, and runs away to lead a life of a fugitive in the swamps. He is finally captured, whipped, and maimed, but not before he casts a powerful voodoo curse at his master and his plantation. He dies a heroic death, with the last words that he goes "To--Africa." Cable once said that he "meant The Grandissimes as truly a political work as it ever has been called." It is a political work in that $Bras-Coup{\acute{e}}^{\prime}s$ personal rebellion is associated with much-feared slave revolts, especially the black revolution in San Domingue/Haiti. There is also $Honor{\acute{e}}$ f.m.c. (free man of color), one of the narrators of "The Story of $Bras-Coup{\acute{e}}$" and a stand-in for the Freedmen in the postbellum United States, who nurses his own insurrectionary flame. Through these figures Cable makes a "terrible suggestion" that a black revolution is on the horizon unless whites would not mend their ways soon.

  • 작약절편을 접종하면 배지와 절편이 흑갈색으로 변하고 수 이로부터 배양이 죽기 시작하는데 배지성분 중에 이를 조장하는 물질이 있음을 발견하였다. 즉 변색의 주원인은 철분과 염화칼슘(Cacl$_2$)이었고, 절편을 괴사시키는데 가장 큰 영양을 미친 것은 NO$_3$었다. 이 결과를 토대로 피해가 비교적 적은 1/4 MS를 번식용 배지로 이용하여 식물체의 모든 부분을 배양하였을 때 조직으로부터 재생은 전혀 일어나지 않았다. 다만 줄기절편에서 이미 형성된 액아가 유식물체로 성장하기도 하였으나 건전한 것으로 계속 성장하지 못하였으며 이것을 다시 번식체로 이용할 때는 초기 배양의 절편에서 나타나는 현상과 같은 원인으로 인하여 생존하지 못하였다.

  • The growth of red and black pines in Muan, Seochen, Gapyeong and Kochang areas was compared by means of the growth of annual ring width and stem analysis to study the process of damages caused by pine needle gall midge. Red pine forest of Seocheon area began to suffer by pine needle gall midge from 1961 and the damage was to becoming severe from 1967. The damage became so intense tha tmany forests are withering to death from spring of 1975. Black pine forest also began to suffer from 1973. Red pine forest of Muan area was supposed to be suffered from 1973. Red pine forest of Kochang area suffered by pine needle gall midge from 1967. It seems that the damage became severe from 1973 and that black pine forest was also badly damaged from that time. Red pine forest of the control plot, Gapyeong area, began to suffer from 1967 and it also became intense from 1973. Although the areas of Seocheon, Muan, Kochang, and Gapyeong are different from each other in terms of locality and the infitration period of pine needle gall equally from 1967 due to mass development of population or other factors and the damage became more intense from 1973. Black pine forest was also badly damaged from that time. Black pine seems to be stronger in insect resistant than red pine. This can be justified by the fact that it began to suffer belatedly in each area and the degree of damage is moderate. The damage of Seocheon area is the severest following Kochang. Muan area is relatively moderate but the forest becoming decrease in growth.

  • In United States black mothers have consistently been treated as national outsiders, as women whose children, although ostensibly entitled to full citizenship, are in practice rarely provided with equal protection within the nation′s borders or under its laws. From the time he began writing in the aftermath of the failures of national Reconstruction, the African American public intellectual and political activist W. E. B. Du Bois realized that a truly effective anti-racist politics would also have to contend with the particular ways in which U.S. racism targeted black mothers. In short, he understood that an effective anti-racism would necessarily have to be a form of anti-sexism. This article examines the myriad ways in which Du Bois attempted to reconstruct the relationship between race and reproduction in the interest of producing anti-racist, anti-nationalist, as well as internationalist thinking. In so doing it treats the various representations of black maternity and child birth that Du Bois created, and elaborates on the rhetorical and political function of these representations in combating the racialization of national belonging on the one hand, and in articulating universal black citizenship, or what this article theorizes as racial globality on the other. The article begins by considering Du Bois′s attempts to transcend ideas about the racialized reproductive body as a source of national belonging within the United States, particularly his efforts to contest the idea of the reconstructing nation as a white nation reproduced exclusively by white women. Through analysis of Du Bois′s depiction of the birth and death of his son in his monumental work The Souls of Black Folk (1903) it demonstrates his reluctance to build an anti-racist politics founded on the idea that belonging within the nation is something that can be bestowed by one′s mother. The article proceeds by turning to Du Bois less well-known romantic novel, Dark Princess (1928) in which, by contrast, he depicts the birth of a "golden chi1d" who belongs not only within the United States, but within the world. This child, the son of an African American man and an Indian Princess, is cast as a messenger and messiah of a utopian alliance between pan-Asia and pan-Africa. In exploring the relationship between these two reproductive portraits, the article moves from a discussion of Du Bois′s critique of the ideological construction of the U.S. as a white nation reproduced by white progenitors, to an examination the literary figuration of a b1aek mother out of whose womb a black diasporic anti-imperialist alliance springs. In contrast to previous scholarship, which has tended to focus on the critique of U.S. racial nationalism that Du Bois expressed in his early work, or on the internationalism that he later embraced, this article pays close attention to how Du Bois′s anti-nationalist and internationalist politics together subtended by subtle, but constitutive, sexual politics.

  • Background: Breast cancer is the second leading cause of cancer death for women in the United States. Differences in survival of breast cancer have been noted among racial and ethnic groups, but the reasons for these disparities remain unclear. This study presents the characteristics and the survival curve of two racial and ethnic groups and evaluates the effects of race on survival times by measuring the lifetime data-based half-normal model. Materials and Methods: The distributions among racial and ethnic groups are compared using female breast cancer patients from nine states in the country all taken from the National Cancer Institute's Surveillance, Epidemiology, and End Results cancer registry. The main end points observed are: age at diagnosis, survival time in months, and marital status. The right skewed half-normal statistical probability model is used to show the differences in the survival times between black Hispanic (BH) and black non-Hispanic (BNH) female breast cancer patients. The Kaplan-Meier and Cox proportional hazard ratio are used to estimate and compare the relative risk of death in two minority groups, BH and BNH. Results: A probability random sample method was used to select representative samples from BNH and BH female breast cancer patients, who were diagnosed during the years of 1973-2009 in the United States. The sample contained 1,000 BNH and 298 BH female breast cancer patients. The median age at diagnosis was 57.75 years among BNH and 54.11 years among BH. The results of the half-normal model showed that the survival times formed positive skewed models with higher variability in BNH compared with BH. The Kaplan-Meir estimate was used to plot the survival curves for cancer patients; this test was positively skewed. The Kaplan-Meier and Cox proportional hazard ratio for survival analysis showed that BNH had a significantly longer survival time as compared to BH which is consistent with the results of the half-normal model. Conclusions: The findings with the proposed model strategy will assist in the healthcare field to measure future outcomes for BH and BNH, given their past history and conditions. These findings may provide an enhanced and improved outlook for the diagnosis and treatment of breast cancer patients in the United States.
