A virus isolate collected from infected paprika (Capsicum annuum var. grossum) was characterized as Potato virus Y (PVY) based on biological, serological, cytopathological, and molecular properties. In host range studies, the paprika isolate produced the mosaic symptom on some tobacco, tomato and pepper (Capsicum annuum). A new paprika isolate also infected potato cultivars which is different biological characteristic compared to the other popular potyvirus infecting paprika, Pepper mottle virus (PepMoV). Previously reported PVY strains, $PVY^o$ and $PVY^N$ did not infect pepper and typical PepMoV isolates did not infect potato. Distinctive inclusion patterns of the scroll, pinwheel, long laminated inclusions, and helper components in the cytoplasm of infected cells were also different to those observed by the typical PVY isolate infections. However, the paprika isolate reacted to the monoclonal antibody of $PVY^N$ strain with high absorbance readings. RT-PCR amplification, cloning, and sequencing of the 3' untranslated region and a part of coat protein gene also added additional evidence of the paprika isolate as the $PVY^N$-related isolate. Multiple alignments as well as cluster dendrograms of PVY-paprika isolate revealed close phylogenetic relationship to the $PVY^N$ subgroup. Altogether, these results suggest that a new PVY isolate infecting paprika contained distinct characteristics compared to the other previously described PVY strains with closer relationship to the $PVY^N$ strain.

경주 교동 최씨가 소장 추수기(秋收記)·수세기(收稅記) 자료의 전존 현황과 특성

최주희 ( Choi Joo Hee ) 한국고문서학회 2021 古文書硏究 Vol.59 No.-

경주 교동 최씨가[최부자댁]에서 소장하고 있는 334건의 추수기·수세기 자료는 교동 최씨 가의 지주 경영 방식을 파악할 수 있는 중요한 문서군이다. 이중 274건은 경주시와 울산 북부 지역 일대의 논에서 지대를 수취하기 위해 작성된 추수기 자료들이다. 최씨가의 추수기에서 확인되는 주요한 특징은 다음과 같다. 첫째, 干支를 기준으로 작성연대를 추정하였을 때, 19세기 후반부터 일제시기 전반에 이르는 시계열 분포를 보인다는 점이다. 둘째, 같은 해에 작성된 여러 형태의 추수기가 남아 있고, 추수기 사이에 모종의 상관관계가 확인된다는 점이다. 셋째, 일제시기까지 대부분의 논에서 打租의 방식을 적용하여 추수기를 작성하였다는 점이다. 비슷한 시기 다른 지역의 추수기에서 확인되는 지대수취 방식은 대부분 執租와 賭租인데 반해, 교동 최씨가의 추수기는 作人과 種子, 稅米까지도 공동 분담하는 형식을 띤 것으로 보인다. 이 때문에 추수기 상에 作人과 斗落, 種子·卜價를 먼저 쓰고, 추수 후 이를 공제하여 반분한 내역을 나중에 기재하는 방식으로 추수기를 작성하였다. 실제로 경주지역 작인들 사이에서 최씨가의 지대수취 방식을 ‘단갈림한다’고 표현하였다. 한편 교동 최씨가에서는 밭작물인 보리와 콩 수확을 관리하고 지대를 수취하기 위한 목적에서 별도의 수 세기를 작성하였으며, 현재 남아 있는 건수만 60점으로 확인된다. 추수기에 대한 다양한 사례 연구가 발표된 바 있지만, 밭작물의 지대수취 내역을 이처럼 오랜 기간 수세기 형식으로 작성한 경우는 드물다. 일부의 사례를 검토한 것이기는 하지만, 최씨가의 추수기에서 확인되는 평균 지대량은 당대 다른 지역의 지대량과 큰 차이를 보이지 않는다. 반면 작인에게서 거둔 보리와 콩의 평균 지대량은, 도조의 방식으로 수취하였기 때문에 절대 생산량을 짐작하기 어려움에도 불구하고 현저히 적은 액수로 파악된다. 이는 최씨가에서 가경지를 제외한 나머지 밭을 작인들에게 대여해주고 최소한의 지대만 수취한 결과로 여겨진다. 이처럼 최씨가의 지주 경영은 당대 다른 지역 사례와 차별되는 측면들이 있다. 본고에서는 전체적인 자료의 현황과 작성방식을 분석하는 데 논의의 초점을 맞추었기 때문에, 향후에는 본고에서 미처 다 해결하지 못한 부분들을 보완하여, 구체적인 지대량의 추이를 살펴보기로 하겠다. Over 330 historic materials on harvest season possessed by ‘Rich Men’ Gyeongju Choi clan in Gyeongju Gyodong are important documents that can be used to reveal Rich Men Choi’s unique landowner management cases. Among which, 274 are the data written during harvest season for the purpose of receiving rent from the land distributed sporadically in Gyeongju and northern part of Ulsan. The major characteristics identified in Rich Men Choi’s historic house are as follows. First, when estimating the whole data, it showed chronological distribution from the late 19^th century to the first half season of Japanese occupation. Second, different types of harvest materials written during the same year co-existed and a certain correlation between them is identified. Third, up to the Japanese colonial period, most paddy fields of Gyeongju Choi clan applied ‘Tajo(打租: receiving a rent with a half-dividing of the harvest)’method. Rent acquisitions identified in other regions in contemporaries were ‘Jipzo(執租: adjusting rent rates before harvesting)’ or ‘Dojo(賭租: receiving a rent with a certain amounts of harvest)’. However Rich men Choi clan shared in half of seeds and rice straws with tenant farmers. So among tenant farmers in Gyeongju, Rich men Choi’s rent acquisition method was called as ‘Dangalim(indicating 5:5 allocation).’ On the other hand, Rich men Choi wrote separate materials to menage barley-farm product and bean harvest and there were now 62 of them have been remained. Various case studies on harvest records of paddies have been published, but few rent aquisition cases from harvest of bean and barley have been identified. Rich men Choi’s average rent identified during harvest season does not show a big difference from the rent amount in other regions, although it reviewed a part of all cases. But the average rent of barley and bean collected from the tenant farmers is significantly low despite the difficulties in guessing the absolute production because they received rent in the way of Dojo. This is considered as a result of lending the rest fields except the arable lands of Rich men Choi to tenant farmers and receiving the minimum rent. Like this, Rich men Choi’s landowner management has a difference from the cases of other regions. In this paper, the focus is on analyzing the current status of the entire data and how it was written. So further studies need to complement the insufficient parts that were not resolved in this paper and reveal the specific historic points of view about Rich Men Choi’s landowner management case.

Viability of sprout seeds as affected by treatment with aqueous chlorine dioxide and dry heat, and reduction of Escherichia coli O157:H7 and Salmonella enterica on pak choi seeds by sequential treatment with chlorine dioxide, drying, and dry heat

Choi, S.,Beuchat, L.R.,Kim, H.,Ryu, J.H. Academic Press 2016 FOOD MICROBIOLOGY Vol.54 No.-

<P>Germination rates of 11 types of sprout seeds (alfalfa, broccoli, kohlrabi, kyona, mustard, pak choi, red kohlrabi, red radish, red young radish, tatsoi, and violet radish) treated with ClO2 (200 mg/ml, 5 min) or dry-heat (80 degrees C/23% relative humidity [RH], 24 h) were determined. Pak choi, red radish, and tatsoi seeds showed highest tolerance to both ClO2 and dry-heat treatments. Next, pak choi seeds were inoculated with Escherichia coli O157:H7 (5.4 log CFU/g) or Salmonella enterica (4.8 log CFU/g) and sequentially treated with ClO2 (200 mg/ml, 5 min), drying (45 degrees C/23% RH, 24 h), and dry heat (80 degrees C/23% RH, 48 h). E. coli O157:H7 was inactivated, but S. enterica was not eliminated (>3.8 log CFU/g reduction). Pak choi seeds inoculated with the pathogens were treated with ClO2, drying, and dry heat and subsequently sprouted for 5 days. When seeds were not completely decontaminated, initial populations of E. coli O157:H7 and S. enterica on seeds (<1.0 log CFU/g) increased to >5.3 and >8.4 log CFU/g of sprouts, respectively. This study shows that sequential treatments of pak choi seeds with ClO2, drying, and dry heat are effective in reducing large numbers of E. coli O157:H7 and S. enterica without loss of seed viability.

1920년대 출판경영인 崔永澤과 『立身冒險談』번역

최희정(Choi, hee-jung) 부산경남사학회 2017 역사와 경계 Vol.103 No.-

이 연구의 목적은 3.1운동 전후 『태서문예신보』에서 『매일신보』에 이르기까지 최영택의 행적과 활동을 성공주의를 유포한 자조론 계열 지식인으로서 검토하는 것이다. 이를 위하여 최영택이 『매일신보』에 번역·연재한 『자조론』아류 서적인 『입신모험담』과 메이지 후기 일본에서 생산된 원전 『입신모험담』을 비교하여 그 첨삭된 항목과 내용을 중심으로 양자를 분석하였다. 또 메이지 후기 일본과 1920년대 식민지 조선이라는 양자의 다른 사회적 상황과 조건 아래 성공주의 전파가 가지는 사회적 기능과 효과의 차이도 논의하였다. 최영택은 『태서문예신보』를 통해 등단한 ‘무명시인’으로 알려져 있었는데, 이 연구를 통해 그가 이 잡지의 사생첩 기자로도 활동한 새로운 사실을 밝혔다. 이에 더하여 1920년대 초 『여자시론』창간과 경영에 참여한 최영택과 동일 인물이라는 점 또한 밝혔다. 무엇보다 최영택을 비롯한 『태서문예신보』의 주요 집필진들이 성공담론 유포에 적극적이었으며, 이 잡지가 육당의 『자조론』이 출간된 1910년대 말 식민지 지성계의 새로운 경향을 반영한 잡지로서의 성격을 가졌음을 제시하였다. 한편 1920년대 초 최영택이 여성전문잡지 『여자시론』 『부인계』의 창간을 주도하면서, 가족경영의 출판사 문창사에서 잡지경영인으로서 활동한 것을 식민지 사회에서 출판업으로 입신성공하려는 그의 지향성 및 『입신모험담』번역의 배경으로 파악하였다. 최영택이 번역한 『입신모험담』은 1920년대 초 조선총독부 식민정책의 충실한 전파 매체였던 『매일신보』의 번역·연재물로서 기획된 것이었다. 원전 『입신모험담』은 러일전쟁 시기 일본 국내 입신출세의 길이 원활하지 않은 상황에서 청년들의 해외 식민지 진출을 종용하는 『자조론』아류 서적류에 속했는데, 이것은 일본의 제국주의 확장에 기여하는 논리를 제공해주었다. 한편 1920년대 초 『매일신보』의 번역·연재물로서 기획된 『입신모험담』을 통한 성공주의 전파는 일본의 식민정책에 협력하는 사회적 효과를 가졌음을 시사하였다. 이 연구는 3.1운동 이후 1960∼70년대에 이르기까지 한국사회에서 장기간 생명력을 유지한 세속적 성공주의와 그것의 전파에 기여한 지식인의 계보를 찾으려는 노력의 일환이다. 이 연구에서 제시한 세속적 성공주의 전파에 기여한 이른바 자조론 계열 지식인과 이들에 대한 고찰은 우파 식민지 지식인 연구에 새로운 轉機가 될 수 있을 것이라고 기대한다. The purpose of this paper focuses on the study of, Choi young-taek, a translator and magazine editor who was trying to succeed in the colonial Korea in the 1920’s. I examined that he had belonged to a right-wing intellectual who accepted Self–Help in colonial Korea. He was influenced by Self–Help or something similar and then began to serialize a translated book, Adversity leads to one’s success(『立身冒險談』) that tells stories about successfully challenged people in The Daily Newspaper. I compared differences in social function between a original book had affected youths in the late Meiji Japan and 「Adversity leads to one’s success」 series in The Daily Newspaper in 1920’s Korea. I think that his conduct of translation expressed a drive to succeed. He wrote poems in the journal of literature and the arts(『泰西文藝新報』) in the late 1910’s and had been known to be not a famous poet. I found that he played an important role in the journal of Literature and the arts as an editor and reporter. It wasn’t simply to introduce western literature and the arts but reflected the point of view of Choi nam-sun in the late 1910’s. Choi nam-sun translated Self-help into Korean in 1918. As you know, It was a turning point in change of the social meaning of ‘self-help’, the keyword of Self-help to be used national ideology that was translated into Korean in the late of Great Han empire. Choi young-taek was an editor and reporter in the women’s discourse(『女子詩論』), a public magazine of Chosen women’s education center, and he published Women’s world(『婦人界』) his own company in the early 1920s. His experience of the journal of literature and the arts at the time of the late 1910’s probably had affected him to be a magazine publisher in the early 1920s. He was a member of munchangsa(文昌社), the family-owned publisher which had been founded in the early 1920s and published magazines. I think that his conduct to have a job as a publisher was related to the will to succeed. As I said before, He serialized a translated book, Adversity leads to one’s success. The source of translation, stories of people who successfully challenged by adversity, was a type of Self-help in Japan. As we know, Self-help was a kind of books which have to be read for a purpose of the success of an individual. In conclusion, Choi’s translation of stories about successfully challenged people realized a value of Self-Help, it would have helped Japanese imperialism to rule colonial Korea. I believe that it is need to study right-wing Korean intellectuals like Choi young-taek who accepted Self-help in modern Korea.

배구경기의 서브 기능 테스트 평가모형 연구

최희남(Choi Hee-Nam) 한국체육과학회 2001 한국체육과학회지 Vol.10 No.1

The purpose of this study was to verify the validity and reliability on the 4 types of volleyball serve skill testing model. Subjects were 2 grade women's middle school(n=122) student which had practiced underhand serve for 6 week before the trial. They were tested 4 types of volleyball serve skill testing model in randomly order. The 4 types of testing model included AAHPERD, Russell-Lange Choi's model and new designed professional model which was invented by physical education teacher at middle school. We tested twice in randomly order and evaluated the validity, reliability and skill improvement on the 4 types of volleyball serve skill testing model. The results were as follows; 1) There were high correlation(r=.80) in validity among 4 types of volleyball serve skill testing model(p<01). 2) We examed a pre and post serve skill test for each model, and there were significant correlation in reliability for Choi's model(r=.839) and AAHPERD(r=.794) in order. 3) For the compensating the validity and reliability on the 4 type testing model, we have compared the scatter gram to normal curve and evaluating the skeness and kurtosis. Ther were high values on the Choi's model which was .833 and AAHPERD(.675) in skewness. In addition, there were positive value in kurtosis on the Russel-Lange which was .037 and negative values on the 3 testing model. 4) It has showed that success of serve test was 63.5% following 6 week practice and 30% of the students did not make any serve in the trial. 5) There were significant correlation between physique and serve skill among 4 types of volleyball serve skill testing. Specially, we have verified that height showed highest correlation with success of volleyball serve(r=.303). In summary, evidence for the combined evaluation of normal curve, reliability and validity on the 4 types testing model, we have concluded that choi's model showed the best evaluation method for middle school student. Furthermore, Choi's model revealed the easiest way to drawing court in class exam. Therefore, we recommended that Choi's model was the most valuable underhand volleyball serve skill testing model among the 4 model and very effective testing method for middle school student.
