Changes in the concentrations of glucosinolates and related compounds in different extracts of Dolsan leaf mustard kimchi (DLMK) and Dolsan leaf mustard pickles (DLMP) were during storage investigated. Samples were kept at 0oC for 35 days and collected at 7 day intervals. The leaves and stems of DLMK and DLMP were refluxed for 24 h with 50% acetonitrile, and the extracts were analyzed by LC-PDA/MS/MS. The main glucosinolates detected in DLMK were sinigrin, gluconapoleiferin, glucobrassicanapin, and gluconapin, whereas those in DLMP were sinigrin, gluconapoleiferin, glucobrassicanapin, glucobrassicin, and glucoerucin. Sinigrin concentrations were quantified by UV absorption at 228 nm. Sinigrin concentrations in the leaves and stems of DLMK on the day of preparation were 2.14 mg/g and 2.25 mg/g, respectively, and those on day 35 after preparation were 1.25 mg/g and 1.00 mg/g, respectively. DLMP showed a similar trend: the concentrations in the leaves and stems on the day of preparation were 2.04 mg/g and 0.29 mg/g, respectively, whereas those on day 35 after preparation were 0.59 mg/g and 0.41 mg/g, respectively. Thus, sinigrin concentrations decreased during storage.

오선경,Oh, Seonkyung 한국문헌정보학회 2017 한국문헌정보학회지 Vol.51 No.3

시각장애인에게 대체자료는 정보접근 및 이용, 지식정보 격차해소, 사회참여 및 통합에 매우 중요한 요소이다. 그럼에도 불구하고 대체자료는 최근까지도 점자도서관 등의 자발적 노력과 자치단체의 재정지원 하에 개인의 요청이나 담당자의 판단으로 제작되고 있기 때문에 그 범위가 문학자료와 교양 취미도서로 한정되고 중복제작 될 뿐만 아니라 대체포맷 또한 매우 제한적이다. 이에 본 연구에서는 국내외 도서관 및 관련 단체의 대체자료 제작사례를 분석하고 시각장애인도서관과 시각장애인을 대상으로 설문조사 방식을 적용하여 대체자료 제작현황과 인식을 조사 분석하였다. 이를 바탕으로 대체자료 제작 및 이용 활성화를 위한 개선방안을 제시하였다. Alternative materials for the visually disabled are very important factors for accessing and using information, dissolving the knowledge information gap, social participation and integration. Nevertheless, since alternative materials have been produced, until recently, even under the voluntary efforts of the braille library and the financial support of local governments, the scope of the materials is restricted to literary materials and hobby books, duplicated in title, and limited in format. In this study, we investigated and analyzed the cases of domestic and international library and related organizations' alternative material production and the current state and perception of alternative materials by applying the survey method to special libraries for the visually disabled and the visually disabled. Based on these results, we added suggestions for the improvement for alternative material production and utilization.

The purpose of this study was to investigate the efficiency of water treatment processes using the biofilm in recirculating aquaculture system, to find out the optimum treatment conditions for ammonia removing in recirculating water, and to estimate possibility of reduction the water treatment unit volume in the aquaculture system as maintaining an efficient treatment process. The upflow biofilm process was equipped with two different types of media, such as Saran media and Ceramic media. This study scaled down to the 20% of the original water treatment unit volume, was compared biofilm process using Saran media with using Ceramic media over conditions of 10 cycle and 20 cycle ratio. The experimental results showed that upflow biofilm process using the Ceramic media was appeared to be better for organic removal, whereas, the biofilm process with Saran media was found to be better for ammonia removal. The biofilm process with the Saran media showed above 90% ammonia removal efficiency. When the volume ratio of recirculating water treatment unit to rearing unit was scaled down to the 20% of the original ratio, the ammonia removal efficiency could be maintained to be similar. Therefore, it can be suggested that the treatment unit of the aquaculture recirculating system can be reduced if the upflow biofilm process with the Saran media is used.

오선경,Oh, Sun-Kyung 한국과학기술정보연구원 과학기술정보센터 2003 Journal of Information Science Theory and Practice Vol.34 No.1

최근 정보기술의 급격한 발전에 따른 정보환경의 변화로 대학도서관은 전통적으로 제공하던 이용자 서비스 뿐만 아니라 자료검색 서비스도 웹기반으로 제공하기 시작하였다. 이를 위해서는 모든 유형의 정보자료를 체계적으로 수집 정리 보존하여 이용자의 접근과 검색의 편의성을 높이는 방향으로 웹사이트를 구축해야 한다. 즉, 대학도서관은 소장기능과 접근패러다임을 동시에 수용하는 실물공간이자 가상공간이므로 소장자료의 전자화와 인터넷 봉사기능을 강조하는 게이트웨이 시스템으로 전환해야 한다. 이에 본 연구는 국내 국립대학도서관을 대상으로 웹사이트의 디지털 게이트웨이 기능을 조사 분석하여 문제점을 도출한 다음에 개선방안을 제시하였다. With rapid telecommunication development, university libraries began to provide traditional services as well as web-based services. For the web-based services, university libraries should collect, arrange, and preserve all types of information resources systematically to raise users access and convenience. Therefore, university libraries should be changed into a gateway, which emphasizes electronic collection and role of the internet. That is, university libraries should be a real space as well as a virtual space having collection ability and access paradigm. This research is intended to provide improvement plans through analyzing the collected data.

오선경(Oh Sun-Kyung),이아름(Lee Ah-Reum) 우리말학회 2021 우리말연구 Vol.66 No.-

This study aims to reveal the correlation between academic writing self-efficacy and writing achievement of foreign students attending Korean university. The subjects of this study are 32 intermediate learners and 46 advanced learners. The writing self-efficacy survey used a questionnaire of 24 items and writing achievement measured by their final report scores. As a result, there was no significant correlation between the two factors at the intermediate level. At the advanced level, there was a significant positive correlation between the two factors (r=.346, p<.05). There was also a significant positive correlation between them in the content (r=.351, p<.05) & expression (r=.333, p<.05) categories at the advanced level. However, correlation coefficient is low. Based on this result, some suggestions were presented to improve Korean writing skills for academic purposes. 이 연구의 목적은 국내 대학에 재학 중인 외국인 학부생들의 정의적 요인인 학문적 쓰기 효능감과 쓰기 성취도 간의 상관관계를 밝히는 데에 있다. 중급 학습자 32명, 고급 학습자 46명을 대상으로 학문적 쓰기 효능감 검사를 실시하였고, 기말 보고서 평가 점수와의 상관관계를 분석하였다. 그 결과 중급에서는 두 요인 간 유의한 상관관계를 보이지 않았다. 고급에서는 두 요인 간 유의한 정적 상관관계를 보였다(r=.346, p<.05). 또 보고서 평가 범주 중 내용(r=.351, p<.05), 표현(r=.333, p<.05) 범주에서 효능감과 성취도 점수 간의 유의한 정적 상관관계를 보였다. 그러나 상관의 정도는 낮은 편이었다. 이런 결과를 바탕으로 학문 목적의 한국어 쓰기 능력을 향상시키기 위한 수업 방안을 제언하였다.

오선경(Seon Gyoung Oh),전희정(Hee Cheong Chon) 한국언어치료학회 2016 한국언어치료학회 학술발표대회 논문집 Vol.2016 No.12

Purpose: This study aimed to determine the difference in the perception of stuttering when listening to speech that includes syllable repetitions, both from a child and an adult. Methods: Structured speech was collected from a pre-school-aged child and an adult, from which speech samples were made consisting of syllable repetitions at 1.5 times, 3 times, or 4.5 times per 100 syllables. In each of these samples, the syllable repetitions were further altered to have either one or two repetition units, for a total of six speech samples from each speaker. One-hundred and twenty participants (listeners) were randomly divided into six groups. Each group listened to a speech sample dyad, and provided their perception of whether the speaker was a person who stuttered. Results: When listening to speech samples with ‘2 repetition units+1.5 times per 100 syllables’, there were a significantly greater number of listeners who regarded the adult as stuttering than there were those who regarded the child as stuttering. Conclusions: Listeners recognized syllable repetition in a more permissive manner when listening to the speech of a child than they did when listening to the speech of an adult. Additionally, the frequency of repetitions and repetition units influenced listeners’ perception of stuttering.
