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.

A species of facultative photo-organotrophic, purple, non-sulfur bacterium was isolated from the 47 point at west and south coast of Korea in September 2001. Separated 13 samples of changes with red color under 28~32 ℃, 3000 lux, anaerobe conditions for 7 days cultivated in basal medium. For pure isolation from 13 samples, we used agar-shake tube method (0.4 % agar) and separated 5 strains through 13-repetition test. EGH-24 and EGH-30 was identified as the same strain through the RAPD(Random Amplified Polymorphic DNA)-PCR of strain EGH-9, EGH-13, EGH-23, EGH-24, EGH-30. Four isolates cultivated in synthesis wastewater for wastewater biodegradation test. EGH-24 was selected with efficient wastwater treating strain. Based on the results obtained from morphology, nutrient requirements, major bacteriochlorophyll content, 16S-rDNA phylogenetic analysis, EGH-24 strain may be identified as a new strain of the genus Rhodobacter and named Rhodobacter sp. EGH-24.

The concent of fatty acid, calcium and magnesium of pig's shank according to be extracted hour was examined. The results what investigated are follows ; 1. There were 9 kinds of different fatty acids in water extract of pig's shank by GLC. The composition was not very different between each other. Linolenic acid was increased as much as 276% when extracted f o r 12hrs. but the amount of monounsaturated fatty acid was decreased as much as 30% by extracting hours. The amount of polyunsaturated fatty acid was decreased also by extracting hours. Therefore, p/s ratio was also decreased by extracting hours. 2. The amount of calcium, magnesium was analyzed by chelatemetry. The amount of calcium was 124.7mg% in raw materials, but water extract sample and bone powder showed higher value. In case of magnesium, it was 138.4 mg % in raw materials, but e xtract sample showed less amount and bone powder indicated higher value. Therefore, the amount of calcium and magnesium were the highest value in S_(B1) and T_(B2), respectively.

In spite of nationmide tuberculosis control program, tuberculosis is still prevalent in Korea. Accordingly, tuberculous meningitis also poses one of the main trouble some problems. Recently, We experienced a perplexing case of tuberculous menin-gitis and tubercdoma in a 24-year old female patient. She was admitted to our hospital owing to meningeal irritation sign, aphasia, VI nerve palsy, and ,fever. CSF analysis showed a finding consistent with that of presumptive tuberculous meningitis.. Initial MRI of the brain revealed a large mass(tuhercu1oma) on left parieto-temporal area. Antitubeculous regimen(1soniazid (INH), rifampin(RMP), ethambutol(EMB), pyrazinamide(PZA)} of meningeal dose was given immediately, and her symptoms and signs were dramatically disappeared with a few days after treatment. She was discharged with improved condition and under maintenance treatment of tuberculosis. Follow-up one year after treatment. revealed that the previous lesion was nearly diminished. She showed no symptom at all until she recognized a total blindness of sudden onset on her left eye a t the 18th month of treatment. Brain MRI checked at that time showed multiple masses of tuberculoma scattered over the brain base and one of them invaded left optic nerve. In our opinion, the cause of relapse in this patient might he explained by the selection and ultimate replication of a minor population of resistant strain. Although such relapse is an extremely rare event, we think that we should always pay attention to this possible resistance problem every time we meet patients with tuberculous meningitis.

전기적으로 유도된 니켈핵사시아노페레이트 막전극의 이온교환 특성 : 전위순환법에 의한 NHCF 막전극과 중금속 양이온과의 이온 교환 특성 조사 Cyclic Voltammetric Investigation on the Characteristics of the Ion Exchange between NHCF Film Electrode and Heavy Metal Cations

본 연구에서는 NHCF 막전극과 중금속 양이온과의 이온교환 특성을 조사하기 위해, 먼저 니켈금속 표면에 페로시안 막을 전기적으로 생성시켜 NHCF 막전극을 제조하고, 순수한 니켈금속과 NHCF 막전극을 다양한 중금속 용액에 양극으로 각각 설치하여 순환전위곡선을 측정하였다. -100 mV에서 800 mV까지 10~1,500회 사이클을 연속적으로 반복한 순환전위곡선으로부터 각 중금속의 양이온에 대응하는 산화 및 환원반응의 첨두전류와 첨두전위의 변화 거동을 분석하였다. 또한 전위순환을 종료한 NHCF 막전극의 표면을 EDS로 분석하여 원자 구성비를 조사하였다. 크롬과 아연 용액에서 NHCF 막전극이 갖는 순환전위곡선의 첨두전류는 순환 회수에 따라 급속히 감소하는 반면에, 코발트, 카드뮴, 망간 용액에서는 환원 및 산화 전류가 서서히 감소한다. 코발트와 카드뮴은 막전극에 침적되는 양이 적은 반면에 망간은 많은 것으로 분석되었다. 또한 이온교환 막전극의 성능 감소는 일반 유기물 이온교환체의 평균 성능 감소율인 3%/사이클보다 훨씬 낮은 0.52~0.6%/사이클로 측정되었다. NHCF 막전극을 이용한 전기화확적 이온교환법으로 구리와 철을 분리할 수 없지만 크롬, 아연, 코발트, 망간 등의 분리 및 회수는 가능함을 알 수 있었다. For the investigation of the ion ex- change between NHCF film electrode and heavy metal cation, we have electrically deposited the ferrocyanide film on nickel surface and measured the cyclic voltammograms of both the pure nickel and the NHCF film electrode in various heavy metal aqueous solutions. Cyclic voltammetry was repeated from -100 mV to 800 mV versus SCE for 10 to 1,500 cycles. Peak current density and potential corresponding to the redox reaction in each solution were obtained from the measured cyclic voltammograms. By using EDS we also analyzed the atomic composition of the NHCF film electrode after the 1500th potential cycling. While the peak current density decreased spontaneously with the number of potential cycling in chromium and zinc solutions, it decreased slowly in cobalt, cadmium, and manganese solutions. The deposited amount of manganese on the NHCF electrode was bigger than that of cobalt and cadmium. The capacity loss of the KHCF ion exchanger was 0.52-0.6%/ cycle much smaller than the average loss of 3%/cycle of the conventional organic ion exchanger. It was found that electrically derivatized NHCF film was available to the electrochemical ion exchange for the separation and recovery of chromium, zinc, cobalt, cadmium, and manganese from wastewater, but not for copper and iron.
