Culex pipiens pallens 모기의 Trypsin과 Chymotrypsin에 관한 연구
이미경,姜奭熙 성균관대학교 기초과학연구소 1985 論文集 Vol.36 No.2
Culex pipiens pallens 암모기의 Trypsin과 chymotrypsin에 관하여 pH Ca^++ 이온 농도, 그리고 온도가 효소의 활성에 미치는 영향과 흡혈 후 중장 내 효소 활성의 변화를 조사하여 이를 Aedes aegypti 크기의 효소와 비교하였다. Culex pipiens 모기의 chymotrypsin은 Ca^++ 이온 존재시에 최적 pH가 8.5에서 9.5호 상승하였고 Trypsin 양은 흡혈 후 30시간에 최대에 달했으며, 온도에 대한 안정성에 있어서는 50℃에서 반감 시간이 21초였다. 그러나 이와는 달리 A. aegypi에 있어서는 Chymotrypsin의 최적 pH에 대한 Ca^++ 이온의 영향이 없었고 Trypsin 양은 흡혈 후 24시간에 최대에 이르렀으며 50℃에서의 안정성에 있어서 반감 시간이 100초였다는 점이 상이함을 관찰하였다. 이상의 관찰 결과는 두 종의 흡혈성 모기가 소지하는 Trypsin과 Chymotrypsin 분자 구조 결정의 기본이 되는 아미노산의 조성 및 서열이 서로 다르다고 지적하는 증거가 된다. Trypsin and chymotrypsin like enzymes from the midguts of larvae and the blood fed females of the mosquito, C. pipiens pallens, have been compared with those of A. aegypti. The optimum pH for the chymotrypsin activity from C. pipiens was found to be at 8.5, which rose to 9.5 when 0.03 M Calcium chloride was present in the reaction mixture. Calcium ion had no effects on A. aegypti chymotrypsin activity. Trypsin from A. aegypti was more stable to temperature than that of C. pipiens. Trypsin activity in both species of mosquitoes began to rise by 6 hours post blood metal and reached at the maximum level by 30 and 24 hours post blood meal for C. pipiens and A. aegypti, respectively. The results seem to suggest that trypsin and chymotrypsin like enzymes from these species of mosquitoes may differ in their primary structures.

This study was performed to research the moderating effects of social support in the relationship between acculturative stress of marriage immigrant women’s husbands and family strength. The subjects are aimed at 280 husbands of marriage immigrant women in South Gyeongsang Province. The data were processed by means of an SPSS 22.0 statistical program, which was used to perform descriptive statistics, correlation analysis, multiple regression analysis and moderating effects based on model by Baron and Kenny(1986). The results of this study are summarized as follows. First, the mean score for acculturative stress of marriage immigrant women’ husbands is 2.73 point. as for sub-factors of acculturative stress, they scored highest for multicultural acceptance stress(2.79), followed by discrimination stress(2.72), home culture coveyance(2.67). In addition, the mean score of family strength was 3.43 point and that of social support was 3.43 point. Second, with regard to acculturative stress of marriage immigrant women’s husbands, its total and sub-factors have significant effects on family strength. that is, the higher level of acculturative stress, the lower family strength. Third, as a result of analyzing the moderating effects of social support in the relation between acculturative stress of marriage immigrant women’ husbands and family strength, the moderating effects of social support was identified. Also, social support as a moderating variable has direct and significant influence on family strength, indicating it is similar moderating variable. And the moderating effects of sub-factors of social support was identified. Forth, as a result of analyzing moderating effects of social support in the relation between sub-factors of acculturative stress and family strength, only discrimination stress has moderating effect. On the basis of the results, husbands actively should participate in acculturation program focused on marriage immigrant women. In addition, family counseling program should be vitalized to solve marital conflicts and family conflicts in a multicultural family. Efforts on social support service for marriage immigrant women’ husbands should be made in terms of policy and practice to strengthen the service. 이 연구는 결혼이주여성 배우자의 문화적응스트레스와 가족건강성과의 관계에서 사회적 지지의 조절효과를 알아보기 위해 수행하였다. 연구대상은 경상남도 15개 시·군에 거주하는 결혼이주여성의 배우자 280명을 대상으로 분석하였다. 자료 분석은 SPSS 22.0 통계프로그램을 이용하였으며, Baron과 Kenny(1986)의 모델에 근거하여 조절효과분석을 실시하였다. 연구결과, 첫째, 결혼이주여성 배우자의 문화적응스트레스의 전체 평균은 2.73점으로 보통 이하였으며, 하위요인별로는 다문화수용스트레스가 2.79점으로 가장 높고, 차별감스트레스 2.72점, 자문화전달스트레스 2.67점 순이었다. 사회적 지지의 전체 평균은 3.43점, 가족건강성의 전체 평균은 3.43점으로 보통보다 약간 높은 수준을 보였다. 둘째, 결혼이주여성 배우자의 문화적응스트레스 전체와 하위요인 모두 가족건강성에 유의미한 영향을 주는 것으로 나타났으며, 다문화수용, 자문화전달, 차별감스트레스 순으로 영향을 주었다. 셋째, 결혼이주여성 배우자의 문화적응스트레스와 가족건강성의 관계에서 사회적 지지의 조절효과를 분석한 결과, 사회적 지지의 조절효과를 확인하였으며, 조절변수인 사회적 지지는 직접적으로 가족건강성에 유의한 영향을 주어 유사조절변수임을 알 수 있었다. 또한 사회적 지지의 하위요인인 정서적지지, 평가적지지, 정보적지지, 물질적지지 모두 조절효과를 확인할 수 있었다. 넷째, 문화적응스트레스의 하위요인과 가족건강성과의 관계에서 사회적 지지의 조절효과를 분석한 결과, 차별감스트레스만 조절효과가 있는 것으로 나타났다. 이러한 연구결과에 기초하여 현재 결혼이주여성 중심으로 실시되고 있는 지방자치단체의 문화적응프로그램에 한국인 남편들도 적극적인 참여의 필요성이 제기되었다. 아울러 결혼이주여성 배우자를 위한 사회적 지지 서비스를 강화할 수 있는 정책적·실천적 노력을 해야 할 것이다. 또한 가족건강성 확보 차원에서 다문화가정의 부부갈등, 가족문제를 해결할 수 있도록 관련 기관·단체의 가족상담프로그램을 활성화해야 할 것이다.
동시통역과정에서의 오류와 전략적 대응 -한영동시통역 데이터 분석을 중심으로
이미경 한국통역번역학회 2012 통역과 번역 Vol.14 No.2
Simultaneous interpreting is carried out under severe time constraints as the interpreter is forced to work at Source Language speech delivery speed to process incoming oral messages into Target Language reexpression. While such mode of communication place interpreters liable to errors, it is very difficult to not only correct or repair errors when they occur, but also detect errors when they occur. The aim of this study is to analyze errors during simultaneous interpreting in order to first, find out what types of errors are most frequent during simultaneous interpreting; second, analyze how interpreters repair errors to accomplish communication; and third, analyze the implications of errors in order to propose strategies to deal with errors. For the study, authentic data was collected from an international conference hosted in Seoul. The data analysis showed omission is the most frequent type of errors during simultaneous interpreting followed by shifts in meaning and expressions. While interpreters repaired approximately ten percentage of errors, the analysis of errors showed that some omissions and shifts worked to facilitate effectiveness of communication, which was achieved by means of time saving strategies utilized by the interpreter. Although some of the time saving strategies used by interpreters seemed to violate the principle of faithfulness in interpreting, the strategies helped interpreters overcome time constraints and ease cognitive load as well as enhance the communicative relevance of Target Language expression.

A simultaneous analysis of four nitrofurans (NFs) and chloramphenicol (CAP) in seawater and water for aquaculture, was performed using solid-phase extraction (SPE) and liquid chromatography-tandem mass spectrometry (LC-MS/MS). The detection of NFs and CAP in seafood is prohibited by the Agricultural Products Quality Control Act and the Food Sanitation Act in Korea as well as in the EU and USA. Types of SPE cartridges, optimal pH conditions in water samples, and mobile phases of LC were tested and selected. Target antibiotics were ionized in positive mode for furazolidone and furaltadone and in negative mode for nitrofurantoin, nitrofurazone, and CAP. The HLB cartridge showed more stable recoveries (81-89%), compared to WAX and MCX. The extraction efficiency of the target antibiotics was more than 80% between a pH of 3 and 8. Lower the pH of the water samples, the more stable was their recovery. The mobile phase of ammonium formate and MeOH enhanced the resolution and sensitivity by five times compared with those in previous reports. Moreover, the retention time of the target compounds was accelerated, and the overall analytical time was reduced by 1/2. The accuracy and precision of the analytical method were 85-93% and 3-19%, respectively, and the recovery of internal standards was 83-88%. Instrumental detection limits were 0.18-1.02 ng/L, and method detection limits and limits of quantification were 0.60-3.99 ng/L and 1.92-12.7 ng/L, respectively, which were 20 times higher than those reported in previous studies. The optimized analytical method in the present study can be used as a proactive method for the detection of banned substances in water for aquaculture farms and seawater in coastal areas.
