박효경(Hyo Kyung Park),김성천(Sung Chun Kim) 한국정보과학회 1989 한국정보과학회 학술발표논문집 Vol.16 No.2

본 논문에서는 병렬처리 컴퓨터 시스템의 상호연결 네트워크의 하나인 Zeta 네트워크에서의 PE 대 PE 통신을 연구 분석하였다. 먼저 주어진 임의의 입출력 쌍에 대해서 가장 짧은 연결 경로를 결정하는 방법을 기술하고, 임의의 입출력 순열을 연결할 경우, 그의 위상적 특성으로 인하여 기존의 동형인 MIN들에 비해서 성능면에서 우수하다는 사실을 통신 지연이 작게 걸림을 보임으로써 입증하였다. 이때 통신지연의 척도로는 거처가는 링크(단계)들의 수로 한다.

『金色夜叉』와『장한몽』호칭어의 대조연구 -이름 호칭을 중심으로-

박효경(Park, Hyo-kyoung),백이연(Baek, Yi-Yiun) 한국일본어학회 2021 日本語學硏究 Vol.- No.68

This study explored the use of names in Ozaki Koyo"s Konjiki Yasha(1897-1902) and its Korean adaptation Janghanmong(1913). It is the social norm in both Japanese and Korean that people avoid calling their superiors by name, and add an honorary suffix such as san or ssi to the name. However, it has been pointed out that they cannot be translated directly due to differences in usage of san and ssi. In this study, we compared san and ssi in the Japanese and Korean novels that were published in the early 20th century when these two suffixes began to be commonly used. These novels also share the same content. As a result, it was found that the names were called differently in each novel despite the same settings shared by these novels. The finding are summarized as follows. Firstly, overall, san tended to be used in more diverse situations than ssi. Secondly, the most frequently called person names were last name without the honorary suffix for Konjiki Yasha and first name without the honorary suffix for Janghanmong. Thirdly, kun which is used among men of the same generation, is rarely found in the Korean adaptation. Fourthly, Japanese address terms varied depending on solidarity, but Korean was more sensitive to power such as age. The honorific suffix san was not translated on the ‘san = ssi’ basis in the adaptation process, but was translated according to the situation and context it was used. It was also suggested that there was a change in the usage of ssi rather than that of san when compared with today"s usage. Follow-up studies are needed to track changes through various literatures.

소면적 재배 작물인 맥문동 중 dimethoate(46% EC)와 pyraclostrobin(11% SC)의 잔류특성을 구명하기 위하여 충남 청양에 위치한 맥문동 포장에서 시험을 수행하였다. Dimethoate는 1,000배 희석하여 수확 50일전부터 10일 간격으로 20일전까지 토양 관주 처리하였으며(50-40, 40-30, 30-20), pyraclostrobin 의 경우 수확 50일전부터 7일전까지(50-40-30, 40-30-21, 30-21-14, 21-14-7) 4,000배 희석액을 경엽살포하였다. 시료는 수확 예정일에 일시 수확하였으며, 채취한 시료는 고압 분무기로 세척하고 60℃ 순환식 열풍 건조기에서 48시간 건조하여 건조 맥문동을 조제한 후 잔류농약을 분석하였다. 또한 수확 예정일에 인접하여 살포한 처리구(dimethoate:30-20, pyraclostrobin:21-14-7)의 경우 건조 전 맥문동도 잔류농약을 분석한 후 건조 전과 후의 잔류량 비를 이용하여 가공계수를 산출하였다. 맥문동 중 dimethoate 의 회수율은 85.8-94.1%이었으며, pyraclostrobin과 대사체(BF 500-3)의 회수율은 각각 86.5-118.1과 90.4-117.1%이었다. 건조 맥문동 중 dimethoate의 잔류량은 50-40 처리구에서 검출한계인 0.004 mg/kg 이하이었고 40-30과 30-20 처리구에서 각각 0.012-0.013과 0.025-0.026 mg/kg이었다. 토양 관주처리한 침투성 pyraclostrobin은 뿌리에서 검출되었으며, 수확일에 인접하여 살포할수록 잔류량은 증가하였다. 또한, 최종 약제살포 처리구에서 수확한 시료의 가공계수는 0.104-0.107로 열풍 건조 과정을 거치면서 잔류량은 감소하였다. 이는 열을 가하면 분해되는 dimethoate의 이화학적 특성 때문인 것으로 판단되었다. 건조 전 맥문동 중 pyraclostrobin과 대사체의 잔류량은 각각0.006-0.007 mg/kg이었으나 건조 맥문동 중 잔류량은 모든 처리구에서 검출한계인 0.001과 0.0002 mg/kg 미만이었다. 잎에 살포될 경우 국부 침투성을 가지는 pyraclostrobin은 경엽 살포한 농약이 지하부 뿌리에서 일부 검출되었으며, 가공계수는 0.14-0.16으로 열풍 건조 과정을 거치면서 잔류량은 감소하였다. 이는 비교적 낮은 녹는점 (63.7-65.2℃)과 습한 조건에서 반감기가 짧은 농약의 특성 때문인 것으로 판단되었다.

박효경(Hyo-Gyeong Park),용성중(Sung-Jung Yong),유연휘(Yeon-Hwi You),문일영(Il-Young Moon) 한국정보통신학회 2021 한국정보통신학회 종합학술대회 논문집 Vol.25 No.2

최근 높은 접근성을 기반으로 다양한 콘텐츠가 양산됨에 따라 미디어 콘텐츠 시장이 더욱 활성화되고 있다. 사용자들은 취향에 맞는 콘텐츠를 찾고자 하며, 각 플랫폼에서 콘텐츠의 개인화 추천을 위해 경쟁하고 있다. 효율적인 추천시스템을 위해서는 양질의 메타데이터가 필요하다. 기존의 플랫폼들은 영상의 메타데이터를 사용자가 직접 입력하는 방식을 취하고 있다. 이는 많은 양의 데이터를 처리하는 데에 시간과 비용을 낭비하게 할 것이다. 본 논문에서는 미디어 초개인화 추천을 위해서 영화예고편을 바탕으로, 영상의 YCrCb 컬러 모델을 기반으로 키프레임을 추출하고, 인공지능의 지도학습을 통해 영화 장르를 구별하고 추후 메타데이터 생성을 위한 활용방안을 제안하고자 한다. Recently as various contents are mass produced based on high accessibility, the media contents market is more active. Users want to find content that suits their taste, and each platform is competing for personalized recommendations for content. For an efficient recommendation system, high-quality metadata is required. Existing platforms take a method in which the user directly inputs the metadata of an image. This will waste time and money processing large amounts of data. In this paper, for media hyperpersonalization recommendation, keyframes are extracted based on the YCrCb color model of the video based on movie trailers, movie genres are distinguished through supervised learning of artificial intelligence and in the future, we would like to propose a utilization plan for generating metadata.

朴孝庚 ( Park Hyo-kyung ),黄永熙 ( Hwang Young-hee ) 한국일어교육학회 2021 일본어교육연구 Vol.- No.57

본고는 일본어와 한국어를 학습하고 있는 전공자들이 적극적으로 참여할 수 있는 한일대학간 온라인국제교류학습을 실시하고 목표언어와 문화를 배우는 과정의 이문화 소통능력의 향상에 대해 고찰한 것이다. 온라인국제교류학습은 한국의 H대학교와 일본의 M대학이 3학기 3차례에 걸쳐 지속적으로 실시하였으며, 양교 담당교원의 긴밀한 협의에 의해 만들어진 1차의 학습환경 디자인의 틀에 맞춰 오프닝토크, 소그룹 활동, 총괄의 체계를 수정 보완하면서 진행되었다. 이후 2,3차에서는 소그룹 활동을 늘리고 상호작용할 수 있는 장치를 제공하여 내실을 다졌다. 출석률이 점차 상승하여 1차에 50%에 그쳤던 것이 2,3차에는 90%가 넘는 출석률을 기록하였다. 수강생을 대상으로 설문조사를 실시하였으며, 객관식 척도 선택과 자유기술식으로 나누어 분석하였다. 양교의 학생은 교류학습에 대해 긍적적으로 평가했으며, 교류학습을 통해 언어운용면과 이문화간 소통의 능력이 향상되었다고 답변했다. KHcoder를 활용한 자유기술항목에 대한 분석에서는 양국 학습자들의 의식 변화를 읽어볼 수 있었다. 교류 학습에 관련된 긍정적인 단어들이 나타났으며 언어운용 면의 능력 향상을 교류회의 짧은 기간 동안에는 실제로 체감하기 어렵다는 것을 고려했을 때, 양국 모두 ’자신감, 실력, 향상, 실제, 회화’ 등의 긍정적인 키워드가 나타난 것으로 교류 학습의 의의를 확인할 수 있다. 국제화와 다문화공생시대를 맞아 다양한 수요에 유연하게 대응하고 세계를 무대로 활약할 수 있는 글로벌 인재육성을 위해 지속적이고 효과적인 온라인교류학습을 구축할 필요가 있다. This study conducts online exchange studies between Korea and Japan, where majors who are learning Japanese and Korean can actively participate, and examines the improvement of foreign cultural communication skills in the process of learning the target language and culture. Based on a survey conducted on students, the analysis results are summarized as follows. Online international exchange learning was conducted three times in the third semester, and was conducted by revising the opening talk, small group activities, and general manager's system in line with the first exchange meeting's learning environment design framework. The students of both schools said that they positively evaluated exchange learning, and that the ability to communicate between language management and foreign culture has improved through exchange learning. In the era of internationalization and multicultural symbiosis, it is necessary to establish continuous and effective exchange learning to flexibly respond to various needs and foster global talent who can act on the global stage.

박효경(Hyo Kyoung Park),노현호(Hyun Ho Noh),이재윤(Jae Yun Lee),정혜림(Hye Rim Jeong),이정우(Jung Woo Lee),조승현(Seung Hyeon Jo),경기성(Kee sung Kyung) 한국농약과학회 2018 농약과학회지 Vol.22 No.3

This study was carried out to determine characteristics of dimethomorph and fludioxonil on water dropwort and shallot called minor crops in Korea. The test pesticides, dimethomorph and fludioxonil, were sprayed onto water dropwort and shallot which were collected on final application day and harvest day and then they were analyzed for the pesticide residue. As a result of analysis, residual concentrations of two test pesticides in water dropwort were more high than those in shallot because of characteristic of cops which relatively had broaden surface area. Residual concentrations of dimethomorph on final application day were more high than those of fludioxonil because A.I. (%) (Active Ingredient) considered dilution factor as well as residual concentrations was similarly applied. So, the field tests were correctly fulfilled. Persistance (%) of dimethomorph and fludioxonil on crops was similar twice or third applied plots. It seemed that residual concentrations were high when spraying the pesticides on crops close to harvest day though affected by application time.

This study was carried out to survey the residual characteristic of chlorpyrifos and estimate their residues in squash before harvest. The pesticide was sprayed onto the crop at the recommended and its double rates 10 days before the prearranged harvest and sampling was done at 0, 2,3, 5,6, 7 and 10 days after spraying. The amounts of the chlorpyrifos residue in the crop was analyzed by chromatographic method. Limit of detection (LOD) of chlorpyrifos was 0.005 mg/kg and its recovery ranged from 95.21 to 102.69%. The initial concentration of chlorpyrifos sprayed with recommended dose exceeded its MRL of 0.1 mg/kg but its concentration was less than its MRL 10 days after application. However its concentration in case of the double dose was over its MRL both immediately and 10 days after application. Biological half-lives of chlorpyrifos sprayed onto squash was 2.5 and 2.9 days at the recommended and double doses, respectively. Ten days later, the residual concentration of chlorpyrifos in squash was decreased substantially. The concentration of chlorpyrifos was estimated in squash at the given day using its regression equations. The estimated concentration of chlorpyrifos in case of application with recommended dose was below its MRL at 10 days after application but its concentration in case of application with double dose was over its MRL at 10 days of the prearranged harvest. The rate of the estimated daily intake (EDI) of chlorpyrifos to its acceptable daily intake (ADI) was 282% right after application but it decreased to less than 18% at 10 days of the prearranged harvest.

  The objective of this study was to compare the effects of children"s experiences in fairy tale activities of reading, narrating and dramatizing on their power of linguistic expression. The subjects of this study were 48 five-year old children (23 boys and 25 girls) attending H Kindergarten in Osan-City, Gyeonggi-do. The experiment was designed according to the Latin square design. Nine fairy tales were used in the study, and all of reading activity, narrating activity and dramatizing activity were compositely applied to all the 48 children. Children"s power of linguistic expression was measured through "the activity of writing words coming to the memory" and "the activity of creating stories" as parts of journal writing activities utilizing fairy tales. One-way ANOVA, t-test, and paired t-test were used for data analysis. The results of this study were as follows: A significant difference was found in children"s power of linguistic expression according to experiences in fairy tale activities. Children"s power of linguistic expression was higher when they experienced dramatizing activities than when they experienced reading or narrating activities. The study suggests that fairy tale activity methods must be chosen according to the goal of education and that children must be continuously guided into active journal writing activities.
