Hong, Young-Suk. 2014. Meanings of English to NNESTs in Korean School Contexts. Journal of Linguistic Studies 19(3). 181-209. Drawing on Narrative Inquiry Methodology, this paper examines Korean elementary English teachers’ lived experiences, focusing on the meanings of English they construct. They are located in a particular situation of co-teaching with a native assistant teacher of English. Three participant teachers’ shared stories are unpacked, analyzed, and interpreted narratively. As a result of the study, three meanings of English emerge: Firstly, English is a power. Secondly, English is a burden. Thirdly, English is a teaching content. In sum, the nonnative English teachers in elementary schools constructed and reconstructed repeatedly the meanings of English depending on contexts in which they are located. These multiple meanings of English are expressed when they live and tell their teacher stories, thus forming multiple English teacher identities. The findings from the study give important implications about in-service English teacher education in terms of building their teacher identities. The study suggests the importance of providing in-service English teachers with an opportunity to think about a narrative perspective regarding forming teacher identity with their own English concepts in order to suggest new possibilities for teachers, students, NS assistant teachers, and parents.

김치 발효 숙성기간을 연장하고 신선도를 오랫동안 유지 할 수 있는 김치발효 starter의 개발을 목적으로 최적숙성기에 있는 김치로부터 bacteriocin생성능이 없는 유산균을 분리하여 동정하였으며, bacteriocin생성능이 우수한 L.acidophilus 88을 융합시키기 위해 electrofusion에 대한 최적 조건을 검토하였다. 분리균주는 Lactobacillus속으로 동정되어 Lactobacillus sp. JC-7이라 명명하였다. Electrofusion에 의해 생성된 융합주를 식별하기 위해 streptomycin(2.5㎎/ml)에 내성을 나타내는 Lactobacillus sp. JC-7변이주와 kanamycin(600㎍/ml)에 내성을 나타내는 L.acidophilus 88변이주를 분리하였다. Electrofusion을 100V/㎝, 120msec(72ohms,1670 capacitance) 에서 수행했을 때 융합효율이 가장 양호하였으며 전기장의 세기와 시간이 중가할수록 융합 효율이 현저히 감소하였다. 2가 양이온은 농도가 중가할수록 대체적으로 융합효율을 감소시키는 경향을 나타내었으나 1mM MGCl_2에서는 대조군에 비해 융합효율이 약간 증가하였다. PEG매개에 의한 융합법의 융합효율을 비교한 결과, 융합효율은 chemical fusion<electrofusion<electrofusion+20% PEG순을 나타내었다. Evaluation of Optimum Conditions for the Electrofusion between Lactobacillus sp. JC-7 Isolated from Kimchi and Lactobacillus acidophilus 88. Young-Bae Jo, Hyun-Jung Choi, Hyung-Suk Baik and Hong-Ki Jun*. Department of Microbiology, Pusan National University, Pusan 609-735,Korea-A lactic acid bacterium was isolated from kimchi. The isolated strain was identified as the genus Lactobacillus thrugh its morphological characteristics and named as Lactobacillus sp. JC-7. The optimum conditions for the electrofusion between streptomycin(2.5㎎/ml)resistant mutant of Lactobacillus acidophilus 88 and kanamycin(600㎍/ml) resistant mutant Lactobacillus sp. JC-7 were evaluated. The highest number of fusants were obtained at a capacitance value of 120msec(1670㎌), a field strength of 100V/㎝,and a pulse controller setting of 72Ω. The potimum pH of elecroporation buffer was 7.5 and the concentration of divalent cation was 1mM MG^2+. Electrofusants were efficiently obtained by addition 20% polyethylene glycol to electroporation buffer. The yield of fusion was better than that of using polyethylene glycol mediated chemical induction.

본 연구에서는 연약지반개량공사가 실시된 광양지역을 대상으로 압밀기간동안 개량지반의 물리적, 역학적 변화특성 및 개량효과를 고찰되어 있다. 지반개량전 원지반에서 시료를 채취하고, 모래말뚝 타설직후, 압밀방치중(예상압밀도 50%) 및 압밀완료시(예상압밀도 90%)에도 시료를 채취하여 각각 토질정수를 조사 비교하였다. 그 결과 압밀이 진행되는 동안 지반의 강도는 증가하여, 일축압축강도로 구한 점성토지반의 강도증가율(C_u/P_o)이 0.36이 되었다. 그리고, 일축압축강도로 구한 점성토지반의 강도증가율(C_u/P_o)이 0.36이 되었다. 그리고, 일축압축강도와 함수비는 최대압밀응력에 대하여 유일함수관계를 보이고 있으며, 압밀완료시점(예상압밀도 90%)에서 추정된 비배수전단강도는 측정된 비례수전단강도와 비교적 잘 일치한다. In this study, both physical and mechanical properties of soft grounds are investigated during improvement works of soft grounds in Kwangyang. The properties of soil before ground improvement are compared with the properties of the improved ground after Sand Compaction Pile installation, during consolidation(degree of consolidation 50%), and at the end of consolidation(degree of consolidation 90%). From this result, improvement of the shearing strength of soft grounds can be deserved during consolidation, and the improving rate of shearing strength C_u/P_o is 0.36. The relationship between the shearing strength by unconfined compression tests, consolidation stress and water content shows that both the shearing strength and water content have an unique function relationship. The shearing strength predicted by Rutledge hypothesis shows relatives good agreement with the field strength.

In the mobile Internet environment, we need to perform frequent accesses between a mobile device and a content server for searching or downloading learning materials. In this paper, we propose an efficient prefetching technique to reduce the network cost and to improve the communication efficiency in the mobile dictionary. Contributions of the paper can be summarized as follows. First, we propose an overall framework for the prefetching-based mobile dictionary. Second, we present a method of determining the amount of prefetching data for each of packet-based and flat-rate billing cases. Third, by focusing on the English-Korean mobile dictionary for middle or high school students, we propose a method of determining the words to be prefetched in advance. Fourth, based on these determination methods, we propose an efficient prefetching algorithm. Fifth, through experiments, we show superiority of our prefetching-based method. Experimental results show that, compared with the traditional on-demand method, our prefetching-based method improves the average performance by 9.8%~19.7% for the packet-based billing and by 19.0%~33.2% for the flat-rate billing. These results indicate that our framework can be widely used not only in the mobile dictionary but also in other mobile Internet applications that require the prefetching technique.

사람 위선암에서 cathepsin L의 발현증가

홍원선,홍석일,박인철,손영숙,정훈용,양석균,김해련,민영일 울산대학교 의과대학 1996 울산의대학술지 Vol.5 No.1

cathepsin L은 lysosomal cysteine 단백분해효소로서 기저막(basement membrane)과 세포외기질(extracellular matrix)을 파괴하여 암세포의 침윤과 전이에 중요한 역할을 하는 물질로 알려져 있다. 이러한 cathepsin L에 대한 mRNA 발현도를 5개의 사람 위선암(gastric adenocarcinoma) 세포주와 5명의 위선암 환자에서 채취한 조직에서 방사능으로 표지된 cathepsin L특이 cDNA를 사용한 Northern blot법으로 측정하였다. 위암의 전이병소에서 수립한 세포주인 SNU-5, SNU-16, MKN-45와 Kato Ⅲ에서는 cathepsin L mRNA가 발현되었으나 원발병소에서 수립한 AGS 세포주에서는 mRNA의 발현이 관찰되지 않았다. 5명의 위암 환자에서는 원발병소, 전이가 확인된 임파절 및 암 근처 정상 위점막에서 각각 조직을 채취하여 cathepsin L mRNA의 발현을 측정하였다. 원발병소와 전이병소에서는 모두 cathepsin L mRNA가 발현되었으나 정상 위점막조직에서는 전예에서 mRNA 발현이 관찰되지 않았다. 한편 mRNA의 발현도는 1예에서는 전이병소가 원발병소에 비해 높았으나, 2예에서는 전이병소에서 발현도가 낮았으며, 나머지 2예에서는 원발병소와 전이병소 사이에 차이가 없어, 원발병소와 전이병소 사이에 mRNA의 발현도의 일관성 있는 경향은 관찰되지 않았다. 이상의 결과는 cathepsin L은 위암의 발생과 진행에 있어 암세포의 침윤과 전이를 촉진하는 것 이외에 또 다른 역할을 할 가능성을 시사하고 있다고 사료된다. Cathepsin L, a lysosomal cysteine protease, is known to play an important role in cancer invasion and metastasis by degrading the components of basement membrane and extracellular matrix. The mRNA expression of cathepsin L was determined by Northern blot analysis using a radiolabeled cDNA specific for cathepsin L in five human gastric adenocarcinoma cell lines and five surgical specimens of primary gastric adenocarcinomas, their metastatic lymph nodes and matched adjacent normal mucosae. The mRNA of cathepsin L was expressed in all of the four cell lines established from the metastatic sites, SNU-5, SNU-16, MKN-45 and Kato Ⅲ, while not detected in one cell line established from the primary site, AGS. The mRNA was expressed in all of the five primary and five metastatic cancer specimens tested, while it was not detected in all matched normal mucosae. The intensities of the mRNA expressions, however, did not show the consistent pattern between primary sites and metastatic lymph nodes. These results suggest that cathepsin L may have the other function in addition to facilitation of the invasion and metastasis during the development and progression of stomach cancer.
