        한국토종닭 5품종의 생산능력 및 스트레스 반응 정도

        조은정(Eun Jung Cho ),최은식(Eun Sik Choi),정현철(Hyeon Cheol Jeong),김보경(Bo Kyung Kim),손시환(Sea Hwan Sohn) 한국가금학회 2020 韓國家禽學會誌 Vol.47 No.2

        본 연구는 한국토종닭 5품종 (재래황갈종, 토착로드종, 토착레그혼종, 토착코니시종 및 한국오계)에 대한 생산 특성 및 생리적 특성을 제시하고자 이들의 생산능력, 강건성 및 스트레스 반응 정도를 살펴보았다. 분석 대상으로 총 493수를 공시하고, 생산능력의 평가를 위해 생존율, 체중, 초산일령, 산란율 및 난중을 조사하였고, 강건성 및 스트레스 반응 정도를 측정하기 위하여 텔로미어 함유율, heterophillymphocyte 비율, HSP-70, HSP-90α 및 HSP-90β 유전자 발현율을 분석하였다. 실험 결과, 생존율은 토착로드종이 99%로 가장 높았고, 한국오계가 91%로 가장 낮았다. 발생시부터 50주령까지의 체중은 토착코니시종, 토착로드종, 한국재래닭, 한국오계, 토착레그혼종의 순으로 변동없이 높게 나타났다. 22주령부터 50주령까지의 평균일계산란율은 토착레그혼종이 75%로 가장 높았고, 토착코니시종이 10%로 가장 낮게 나타났다. 생리적 지표 분석 결과, 텔로미어 함유율은 토착로드종이 가장 높았으며, 토착코니시종이 가장 낮았다. Heterophil-lymphocyte 비율 및 HSP-90β 유전자 발현율은 공히 토착코니시종이 가장 높았으며, 토착로드종이 가장 낮게 나타났다. 이러한 결과들은 토착로드종이 스트레스에 저항성이 높고, 토착코니시종이 스트레스에 가장 민감하게 반응함을 의미한다. 이상의 결과들을 종합할 때, 토착코니시종은 한국형 토종 육용 품종으로 개량함이 바람직하고, 토착레그 혼종은 한국형 토종 난용 품종으로 개량하는 것이 바람직할 것으로 사료된다. 더불어 토착로드종은 양호한 생산능력과 뛰어난 강건성을 기반으로 한국형 토종닭 종계 모계통으로 활용하는 것이 바람직하리라 생각되고, 재래황갈종은 우수한 육질을 바탕으로 차별화 된 고급육질형 토종닭 품종으로 개량하는 것이 바람직하리라 사료된다. This study presents the production characteristics and physiological characteristics of five Korean native chicken (KNC) breeds consisting of Hwanggalsaek Jaeraejong (HJ), Korean Rhode Island Red (KR), Korean White Leghorn (KL), Korean Brown Cornish (KC), and Korean Ogye (KO). We investigated their production performances, vitalities, and stress responses. We measured the survival rate, body weight, age at first egg-laying, hen-day egg production, egg weight, amount of telomeric DNA, heterophil-lymphocyte ratio (H/L ratio), and heat shock protein (HSP)-70, HSP-90α and HSP-90β gene expression levels for 493 KNCs. The survival rate was highest in KR, and lowest in KO. Body weights were steadily high in the order of KC, KR, HJ, KO and KL. Average hen-day egg production was highest in KL, and lowest in KC. While the amount of telomeric DNA was highest in KR, and lowest in KC. Furthermore, both the H/L ratio and the HSP-90β gene expression level were highest in KC, and lowest in KR. These results indicated that the KR breed was highly resistant to stress, whereas KC was more susceptible to stress. Taken together, it is considered that with improvements the KC breed would be more suited to be used as a Korean broiler breed while KL would be more appropriately used as a Korean layer breed. In addition, it is considered that the KR breed is appropriate to be used as a maternal chicken breeder based on good production capacity and excellent robustness, while the HJ breed is desirable to be improved as a high-quality Korean meat breed based on its excellent meat quality.

        廣州語 比較구문 연구

        조은정 ( Eun Jeong Cho ) 한국중문학회 2005 中國文學硏究 Vol.31 No.-

        比較句可分爲相等級, 高于級與低于級的三種. 其中相等級又稱爲平比, 高于級和低于級又稱爲差比. 廣州話高于級的形式與普通話相反, 其述語放在比較對象之前, 但相等級和低于級與普通話相同, 述語放在比較對象之後. 廣州話高于級的最基本句式爲「A+形容詞+過+B」. 這種“過”比較句是受古漢語的影響而形成的. 北方漢語傳播到南方方言的過程當中, 粤方言接受了北方的“過”比較句, 而這種句式又影響到鄰近的方言, 因此潮州話和海南話裏也可以找到與廣州話相同的特色. 値得注意的是, 這些潮州話與海南話竝不是粤方言, 而是閩方言, 但這些閩方言卻具有與粤方言相同的特色. 這是因爲潮州與海南都鄰近於廣東省的關係, 所以這些閩方言都受到粤方言的影響, 而可帶有粤方言的特色.

        The purpose of this study was to identify the relationship between the optimism and hope in middle-aged sport participants. For this purpose, I chose people, 135, who were in sport participants in everyday life. To process the data, I conducted exploratory factor analysis, reliability analysis, and correlation analysis with SPSS 11.0 program and confirmatory factor analysis, structure equation model analysis with AMOS 7.0. The results of this research are as followings. First, optimism had positive effect on pathway thinking of hope. Second, optimism had positive effect on agency thinking of hope. Third, optimism had positive effect on agency thinking compared with path thinking.

        상고중국어 근칭지시사의 접속사로의 문법화 연구

        조은정(Cho, Eun-jeong) 한국중어중문학회 2020 中語中文學 Vol.- No.81

        In this paper, we discussed the ways in which the two proximal demonstratives of CI (此) and SI (斯) are grammaticalized as conjunctions. After a review, we came to the conclusion that the grammatical usage of CI (此) and SI (斯) as conjunctions was different. CI (此) is used when CI (此) from the grammatical structure of “VP, 此+VP” is no longer substituting the antecedent which is then grammaticalized into a clause conjunction that represents the cumulative from the subject, and furthermore evolves into a sentence conjunction that demonstrates the cumulative. SI (斯) is initially used as a parallel phrase conjunction in the grammatical structure of “V+斯+V”, then grammaticalized into a clause conjunction that represents the cumulative word from the subject. From this, we realized that the proximal demonstratives do not change but work as a cumulative as they are grammaticalized into a clause conjunction, and the way in which they are grammaticalized can be different even when compared to other identical proximal demonstratives.

        Hong Kong Government’s Cantonese Notation is a kind of notation that Hong Kong government has marked the Cantonese pronunciation by the Roman alphabet. This notation has been used all the way from British colonial days until now, its main purpose is to record proper nouns, such as names, place names, street names and MTR names in Hong Kong. This notation was enacted for foreigners do not know the Chinese characters and Cantonese pronunciation, so it is marked in English, but there’s a big difference between the original Cantonese pronunciation and this Roman alphabet. In particular, all of aspirated sounds and unaspirated sounds are represented by aspirated sounds, the finals are indicated without distinction of long vowels and short vowels. close-mid vowels and open-mid vowels are also used without distinction. In addition, one final is marked by several finals, and several finals are marked by one final. The homophone and pronunciation of the same Chinese character are marked by several forms.

        선진시기 여성의 호칭법 고찰 -≪左傳≫과 西周 金文 비교를 중심으로

        조은정 ( Eun Jeong Cho ) 중국어문연구회 2015 中國語文論叢 Vol.0 No.71

        This thesis outlines Chinese naming system of Pre-Qin Period and deals with especially female naming. It was found through the consideration of this thesis that Bronze inscription of the West Zhou Dynasty, the unearthed document, and Zuozhuan, the classical document, decribed the appellations for female in diffrent aspects. In other words, Xing, surname was mandantorily used for female and the form of address was very comparatively simple adding ‘Zi’ component of her own name, posthumons titles of either herself or her husband, or country names in the latter while the former shows a charateristics that ‘Ming’ component of her name was also added to the form in Zuozhuan. This thesis considers the forms of appellation of Pre-Qin period systemically and discusses the differences among them. The cause of the differences between unearthed documents and classical ones is further analysed.

        The purpose of this study were 1) to examine the relations of the body satisfaction, self-esteem and body image of female student majoring in dance from high school. the subjects were 238 female students from high school. the instruments for this study were multidimensional body-self relations questionnaire(Brown, Cash, & Mikulka, 1990), body image scale(Rowe, 1996) and self-esteem scale(Rosenberg, 1965, 1979). The data were analyzed by exploratory/confirmatory factor analysis, t-test, ANOVA and MANOVA. Factor analysis showed that body image had four dimensions: attention to grooming, health/fitness evaluation, health/fitness influence, overall appearance evaluation. first, body satisfaction group received highly scores of the level of body image attention to grooming, health/fitness evaluation, health/fitness influence, overall appearance evaluation, and self-esteem than did those in the body dissatisfaction group. second, we found the interaction effects depending upon overall appearance evaluation between the level of body satisfaction and self-esteem.
