Language Socialization Practices of Seven Adolescents of Korean Heritage in the US
Lee.Gi-ven.Song Mi-jeong 한국사회언어학회 2012 사회언어학 Vol.20 No.1
Lee, Gi-venㆍSong, Mi-jeong. 2011. Language Socialization Practices of Seven Adolescents of Korean Heritage in the US. The Sociolinguistic Journal of Korea, 20(1). pp. 135-159. This study explores cultural and linguistic practices, identity negotiation, and power dynamics manifested in language socialization practices in a recreational setting of seven high school and college students of Korean heritage currently residing in the US. In conjunction with interviews, audio-tapings and observations of these students' weekly basketball games serve as the data sources. Analyses of data demonstrate that the basketball game offers a prime context for these students to speak Korean, practice Korean sociocultural values and rules, negotiate their identity, and establish their own position in the group. While they all speak English for the majority of time in their day-to-day interactions, the students mostly use Korean in the basketball setting, particularly when talking about Korea-related topics. In terms of negotiating their ethnic identity, the Korean-born students seem to negotiate their identity more strictly than the US-born students, who appear to negotiate their identity more ambiguously and flexibly. Also, the power and authority to control the interaction seems to depend upon the symbolic and material resources that the students own.
교육과정 개정에 따른 과학의 본성 수준 및 반영 정도 분석 : 2009 개정 교육과정과 2015 개정 교육과정 사례 분석

지난 수십 년간 과학의 본성의 중요성은 지속적으로 강조되어왔다. 본 연구에서는 2009 개정 교육과정에서 2015 개정 교육과정으로 교육과정이 개정됨에 따라 과학의 본성 반영정도와 그 수준이 어떻게 변화되고 있는지 알아보았다. Abd-El-Khalick et al. (2008)의 과학의 본성 정의를 반영하여 구성된 이정원 외(2016)의 NOSAT(Nature of Science analyzing tool) 분석틀을 이용하여 2009 개정 교육과정융합과학 교과서와 2015 개정교육과정 통합과학 교과서의 과학의 본성의 영역과 수준을 분석하였다. 분석 결과 융합과학과 통합과학 모두에서 가장 많이 나타난 과학의 본성 영역은 이론, 관찰추론, 사회문화로 나타났다. 두 교과서 모두에서 암시적인 관점의 서술의 비율이 명시적인 관점의 서술에 비해 높게 나타났다. 두 교과서의 과학의 본성을 서로 비교한 결과 각 출판사의 과학의 본성 서술 방향에 따라 과학의 본성의 빈도 및 명시성의 정도가 서로 다르게 나타났다. 교과서 집필방향에서 명시적인 서술이 더 증가하는 것이 필요하고, 일부 과학의 본성 영역에 편중되어 있는 현상을 줄이고 각 과학의 본성 영역이 균형 있게 배치되도록 하는 것이 필요할 것으로 보인다. Over the past decades, the importance of the nature of science has been emphasized. This study examined how the degree of reflection and the level of the nature of science (NOS) is advancing as the curriculum has been revised from ‘2009-revised-curriculum’ to ‘2015-revised-curriculum’. The area and level of the NOS in ‘Convergence-science’ of ‘2009-revised-curriculum’ and ‘Integrated-science’ of ‘2015-revised-curriculum’ were analyzed using the Nature of Science analyzing tool (NOSAT) which Lee Jeong-won et al. (2016) had made reflecting the definition of the NOS by Abd-El-Khalick et al. (2008). As a result of our analysis, the area of the NOS that appeared most in both ‘Convergence-science’ and ‘Integrated-science’ was ‘Theory’, ‘Inference’, and ‘Social and Cultural embeddedness’. In both textbooks of the curriculum, the proportion of implicit point of view was higher than that of explicit point of view. As a result of comparing the NOS in the textbooks, the frequency and the extent of the explicit descriptions of NOS differed according to the direction toward the nature of science of which each publisher writes. It is necessary to increase the number of explicit descriptions in the direction of textbook writing, and to reduce the phenomena that are biased toward the certain area of NOS and balance each area of NOS.

Background: Mutation of Gs protein subunit (gsp oncogene), detected in about 30∼40% of growth hormone (GH)-secreting pituitary tumors, is associated with an increased long-acting somatostatin analog octreotide sensitivity. However, the mRNA expression of somatostatin receptor (sst) was not changed in the GH-secreting pituitary tumor, regardless of whether they were gsp oncogene positive or negative. This suggests that the expression of genes coding for G_i2α, Pit-1 and the other factors involved in the regulation of secretory activity in somatotrophs is likely to be altered in gsp oncogene positive tumors. We observed the impact of the gsp oncogene on the expression of the genes coding for Gi2, Pit-1 and sst (2&5) in GH-secreting pituitary tumors. Methods: The GH response to octreotide was examined in 13 acromegalic patients before transsphenoidal adenomectomy. Genomic DNA and RNA were extracted from fresh frozen tumor tissues. PCR was performed to amplify and sequence the region between codon 184 and 251 that includes exons 8 and 9 of the Gs gene. Sst2, sst5, G_i2α and Pit-1 mRNA levels were measured by semi-quantitative RT-PCR. Results: Sst2 and sst5 mRNA transcripts were detected in all tumors (7 gsp +, 6 gsp-). The amount of sst transcripts varied considerably varied between the tumors. There were no significant differences in sex, age, tumor size, grade or basal GH levels. Pit-1 and sst2 mRNA levels were not different. In contrast, G_i2 mRNA levels were significantly higher in gsp (+) while sst5 mRNA levels were higher in gsp (-). Conclusion: These data suggests that gsp oncogene may increase Gi2α levels but decrease sst5 mRNA levels. However, Pit-1 and sst2 mRNA expression may not be affected by gsp oncogene. The increased expression of the G_i2α gene might be an inhibitory compensatory response to the action of gsp oncogene

본 논문에서는 고속디지털 가입자선로 모뎀에서 사용될 수 있는 새로운 반향 제거기를 제안하였다. 제안된 반향제거기는 1단계는 FIR필터를 사용하고 2단계는 IIR필터를 사용하는 2단으로 구성된 반향제거기이다. 2단 반향제거기는 종래의 FIR필터에 비하여 계수의 수와 계산의 복잡성이 감소함을 볼 수 있었다. 또한 컴퓨터 시뮬레이션을 통하여 2단 반향제거기는 종래의 FIR반향제거기와 비교하여 더 빠른 수렴률을 갖는 것을 알 수 있었다. This paper proposes a new echo canceller that can be used in a high speed digital subscriber loop modem. The proposed echo canceller is composed of two stages. The first stage of the echo canceller is FIR filter and the second stage of the echo canceller is IIR filter. The two-stage echo canceller offers a reduction in coefficients and computational complexity compared to a conventional FIR filter. It is shown in this paper that a two-stage echo canceller has a faster convergence rate compared to a conventional FIR filter.

본 논문에서는 전이중 디지틀 가입자선로 모뎀에서 사용될 수 있는 새로운 반향 제거기를 제안하였다. 제안된 반향 제거기는 입력신호의 group-delay 왜곡이 없는 linear phase LMS 알고리즘을 사용하였다. Linear phase FIR필터의 홀수/짝수 대칭 성질을 이용한 stochastic gradient descent 알고리즘을 유도하였다. 컴퓨터 시뮬레이션 결과 제안된 반향 제거기는 표준 LMS 알고리즘을 사용한 반향 제거기와 비교하여 수렴률이 증가하고 MSE가 감소한다는 것이 보여진다. This paper proposes a new echo canceller that can be used in a full-duplex digital subscriber loop modem. The proposed echo canceller uses a linear phase LMS algorithm without any group-delay distortion of the input signal. Stochastic gradient algorithm that exploits the odd/even symmetry property of linear phase FIR filter is derived. Numerical results based on computer simulation are given in this paper. It is shown that the proposed algorithm has a faster convergence rate and a lower MSE in comparison with the standard LMS algorithm.

Molybdenum is enriched in the carbonaceous black slate of Ogcheon belt up to ca. 1000 ppm. The black slate in Deokpyeong area, Goesan was examined to reveal the mineralogical form of molybdenum by X-ray diffraction analysis, nuclear activation analysis, scanning electron microscopy, energy dispersive X-ray spectroscopy, and wavelength dispersive X-ray spectroscopy. All results show collectively that molybdenum is present in the form of tiny flakes of molybdenite (MoS2) ranging 1-3 ㎛ in thickness. The molybdenite flakes are scattered in the fine-grained carbonaceous matrix, wedged in muscovite flakes, or included in titanite. Previous works overlooked the molybdenite flakes due to their small grain size and close admixture with opaque carbonaceous materials

This study was conducted to investigated the major characteristics of genetically modified rice of "Milyang 204" originated from Dongjinbyeo compared to a non-transgenic rice varieties Dongjinbyeo and Junambyeo. Basta resistant transgenic rice lines carrying bar gene produced by the Yeongnam Agricultural Research Institute were evaluated for their agronomic characters. The transgenic Japonica rice of "Milyang 204" showed inferior phenotypic traits compared to a non-transgenic rice variety Dongjinbyeo and Junambyeo. On the basis of UPOV (Union Internationale Pour la Protaection des Obtentions Vegetables) and NSMO(National Seed Management Office) the transgenic "Milyang 204" showed difference in some traits out of some agronomic traits, such as leaf color, angle of flag leaf, number of spikelets, culm length, white core and white belly compared to the nontransgenic varieties rice.
