This retrospective clinical study was done based under the delivery records of 146 cases of twin pregnancies in Yonsei University, Severance Hospital and Wonju Christian Hospital from 1977 through 1980 with particular interest in the second twins. Clinical factors, Apgar scores related to neonatal prognosis, and perinatal mortality rate were statistically analyzed and the following results were obtained. The mean - birthweight for A (first) twins was 2,377 grams and for B (second) twins 2,296 grams. In comparison of the percentage of low-birth-weight (less than 2,500 grams) infants, there were more small B twins, but the difference was statistically not significant. Because there were no significant statistical differences in birth weight-grouping between A and B twins, they could be compared with the comprehensive Apgar scores, but this method was also shown to be statistically not significant. In comparison of the percentage of breech deliveries in A and B twins, the percentage was more than three times in B twin (A twin, 7.5 per cent; B twin, 24.0 per cent), and the difference was statistically very significant (p < 0.0005). There were no significant statistical differences between the Apgar scores of A and B twins in reference to the manner of delivery. According to the manner of delivery of B twins, spontaneous vertex delivery and total breech extraction revealed higher infant mortality rate than others. B twins presented by the vertex in 88 cases (61.0 per cent), by the breech in 55 cases (37.0 per cent), and by the shoulder in 3 cases (2.0 per cent). And this therefore disclosed no significant statistical differences in Apgar scores in relation to the presentation. The duration of labor appeared to have no clear correlation with the Apgar scores and the perinatal mortality of A and B twins. The delivery interval between A and B twins was 11.9 minutes on an. averge, varying from 3 to 65 minutes. The length of this interval was not found to have any significant effect on the Apgar scores and the perinatal mortality rate of B twin.

In case that multiple jammers are transmitting the signals which are the same type a general algorithm based on TDOA method cannot estimate the positions of multiple jammers because there are many TDOA measurements including true and false values. This paper, therefore, designs a new algorithm based on TDOA method to localize multiple jammers. In this algorithm, TDOA measurements are obtained by rotating the reference sensor, and then the positions of multiple jammers can be estimated by detecting congregated point among the multiple estimated positions from TDOA measurements. Through computer simulations, it is verified that this algorithm localizes the multiple jammers well. The performance of the algorithm are also analysed by changing the distance between sensors and jammer, and sampling frequency.

GPS 위성 고장과 같은 GPS 신호 이상에 대한 무결성 감시 연구가 진행되고 있다. GPS 신호의 이상 발생은 GPS 위성의 고장, 이온층 지연 오차의 급격한 증가, 제어부분의 항법 파라미터에 대한 잘못된 모델링 또는 고의적 이상, 전자파 간섭 등이 있는 것으로 알려져 있다. GPS 위성 고장의 경우 반송파, 코드, 항법메시지의 오류에 의해 이상이 발생할 수 있다. 본 논문에서는 항법메시지에 이상이 있는 상황을 GPS 시뮬레이터를 이용하여 재현하고, 항법메시지 이상이 GPS 수신기에 미치는 영향을 분석하였다. GPS 항법메시지를 구성하는 프리앰블, HOW의 TOW 카운트메시지와 서브프레임의 ID를 나타내는 비트, 위성상태 관련 비트, 그 외의 항법메시지 이상에 대해 정리하고 이를 재현하였으며, 이러한 이상이 GPS 수신기에 미치는 영향을 분석하기 위하여 위성의 개수, DOP, 의사거리를 통해 관찰하였다. The integrity monitoring of anomalous GPS signal have been researched because of the degradation of GPS satellite performance. It is known that anomalous GPS signal can occur by failure of GPS satellite, sudden increase of ionosphere delay error, SA, wrong modeling for navigation parameters from control segment, and an electromagnetic wave interference, etc. In case of GPS anomaly by satellites can arise from carrier frequency, code and navigation message. In this paper, the scenarios with navigation message errors were made by using GPS simulator, and the influences of GPS navigation message error to receiver were analysed. The anomalies of preamble, bits related TOW count message, subframe ID in HOW, bits related satellite healthy, and the other navigation message errors were described and simulated. Also, the number of satellites, DOP and pseudorange are analyzed to know how the anomalous signal can affect on GPS receiver.

실시간 위치추적 시스템에서 높이 오차를 고려한 TDOA 측정치 기반 테일러 급수 설계 방법

This paper proposes a Taylor-series design method which reduces the height error of the tag when readers are arranged at the same height in 3-dimensional space. The proposed method consists of two steps. Firstly, the planar position is estimated by the Taylor-series method using the TDOA measurement. Next, the height is estimated from the estimated planar position. In order to show the validity of the proposed method, computer simulations were performed for the static case and linear trajectory of the tag. Results show that the proposed method gives convergent estimated position and better height estimate than the Taylor series method.

공동체의 (불)가능 조건으로서의 시인

강희원(Heewon Kang) 한국동서비교문학학회 2015 동서 비교문학저널 Vol.0 No.32

This essay examines how the community can confront the rupture within itself and how the poet can trigger off the process of confrontation on the basis of a close reading of William Wordsworth’s “The Thorn” and Chang-dong Lee’s film, Poetry. The close reading is preceded by the brief reflection of Franz Kafka’s “The Community” and Sigmund Freud’s account of the mythical primal horde in Totem and Taboo. This offers a preliminary clue to what is at stake in “The Thorn” and Poetry, that is, the supplementary relationship between the community and the other expelled from it. The reading of “The Thorn” focuses primarily on the villagers’ effort to establish their community as a field of totality and sameness by keeping Martha at a proper distance. It is the firm barrier erected between the village community and Martha that the narrator, as a version of the Wordsworthian poet, makes problematic by inscribing Martha’s cry within the community’s story. Lee’s Poetry shows us how Mi-ja begins to develop her interest in poetry and finally writes one poem by the end of the month-long course. The important point to retain here is that the process of writing a poem is intimately bound up with the process of confronting with Hee-jin as an absolute exception to the community. This is why this essay, with regard to Poetry, attempts to explore the poet’s mysterious position of reporting or transmitting to the community some of the crazy nonsense or resistance to meaning.

정신장애인과 기본적 인권

강희원(Hee Won Kang) 한국정신건강사회복지학회 2010 정신보건과 사회사업 Vol.35 No.-

우리나라에서 개인이 가지고 있는 사회적 요구가 인권문제로 본격적으로 논의되기 시작한 것은 아주 최근의 일이다. 사실, 얼마 전까지는 기본적 인권은 주로 대(對)국가적 차원에서 일반유산시민의 정치적 자유의 문제로만 논의도어 왔기 때문에, 구체적인 경우에 누구에게 어떠한 방식으로 무엇을 얼마나 기본적 인권으로 확보해줄 것인가라는 문제는 거의 논의되지 않았다. 그래서 자본주의체제 밖에 있는 열외인간에 대한 연민과 연대의 문제가 기본적 인권의 문제라는 것을 거의 인식하지 못하고 있었다. 늦었지만 이제 와서 우리가 정신장애인의 기본적 인권보장을 새삼 법적인 문제로 의식하면서 논의하고자 하는 것도 어쩌면 열외인간의 잔혹사(殘酷史)에 대한 인간적 반성에서 연유한다고 할 것이다. 정신장애인의 인권은 크게 두 가지의 측면으로 나누어서 생각해볼 수 있다. 첫째, 정신장애인이 그 사회에서 얼마나 불합리하게 차별 배제되고 있는가라는 측면에서 정신장애인에 대한 불합리한 차별이나 배제 자체를 인권침해의 문제로 생각하는 것이고, 둘째, 정신장애인이 사회적 일원으로서 인간답게 살아갈 수 있도록 얼마나 많은 배려를 하는가라는 측면에서 정신장애인복지를 인권보장의 문제로 생각하는 것이다. 물론, 이들 양자의 측면은 서로 밀접하게 연관되어 있다. 그래서 본 논문은 정신장애인의 인권문제로서 이들 두 가지의 문제를 개괄적으로 논의하고 있다. A recent medical and social statistics has reported the shocking reality that one in four korean people will suffer from mental illness at some point in their whole lives. The person with mental disorder is subject to prejudice, discrimination and marginalization in almost all aspects of their social lives, labeled as "crazy guy". The social realties are impregnated quite strongly in the legal schemes and practices of korean mental health law, even though human rights are guaranteed as the basic right equally for all people in Korea`s constitutional law. This article is treating Korea`s current legal situations for persons with mental disorders as the problem of the Human Rights. Commonly defined, Human Rights are the rights that belong to an individual or group of individuals as a consequence of being human. The Human Rights Problem of the social weak has been remarkable during recent years. So the issue of human rights of the persons with mental disorders has been made of a very important part of this problem. It belongs to the fundamental human rights of the persons with mental disorders to request the unjust discrimination prohibition and the appropriate socal welfare. So especially the unjust discrimination against the people on the grounds of mental disorder should be a violation of human rights.
