한・독 간 직업교육 교류에 관한 고찰: 역사적 배경과 현재적 의미
유진영,김기홍 한독교육학회 2023 교육의 이론과 실천 Vol.28 No.2
본 연구는 한국과 독일 간에 직업계고를 중심으로 이루어지고 있는 교육교류를 살펴보고 이러한 교류의 역사적 배경과 현재적 의미를 고찰하였다. 한국과 독일 간의 교류는 냉전 시기인 1960년대부터 시작되었고, 특히 경제 협력과 기술협력을 위한 개발 원조에 기반을 두고 있다. 이후 중등단계의 직업교육 부문에서 지속적이고 다양한협력관계가 이루어지고 있으며 그 배경으로 양 국가의 사회, 경제적 문제에 대한 실리적 해결이 주목된다. 독일 측에서는 최근 이민법개정을 통해 자국의 전문인력 및 숙련인력 부족을 해결하고자 하고 한국 측에서는 청년들이 더 나은 자격 및 노동시장 진입을 목표로 하는 각각의 이해관계를 갖고 있다. 이러한 이해관계에 호응하여 국내에서는 공공부문, 민간부문, 학교간, 시도교육청 등에서 활발하게 직업교육을 중심으로 교류가 진행되고 있다. 문헌연구와 관련 인터뷰를 통해 최근의 직업교육 교류를 고찰함으로 양국의 교육교류가 주는 시사점과 전망 에 대해 논의하였다. A study on exchanges through vocational education between Korea and Germany: Historical Background and Present Meaning Yu, Jinyoung(KRIVET, Research Fellow)/Kim, Kihong(KRIVC, Counsultant) This study aims to examine the exchange and its meaning centered on the recent vocational high school between Korea and Germany. Exchange relations between Korea and Germany began in the 1960s during the Cold War, and are based on development aid, especially for economic cooperation and technical cooperation. Continuous and diverse cooperative relationships are taking place in the middle-level vocational education sector between Korea and Germany, and against this background, it is important to consider the recent social and economic backgrounds of the two countries. On the German side, the recent revision of the immigration law aims to solve the problem of the shortage of professionals or skilled workers in the country, and on the Korean side, young people have their respective interests to enter the better qualifications and labor market. Germany is trying to solve the problem of the shortage of professionals or skilled workers in its country through the recent revision of the immigration law, and on the Korean side, young people have their respective interests to enter the better qualifications and labor market. In response to these interests, exchanges in the field of vocational education are actively taking place in the public sector, the private sector, schools, and municipal and provincial offices of education. By examining recent vocational education exchanges through literature research and related interviews, we tried to discuss the implications and prospects of educational exchanges between Korea and Germany.

Purpose Non-small cell lung carcinoma (NSCLC) comprises 75-85% of all lung cancers, and approximately 25% of all NSCLC patients develop brain metastasis. There are no reliable markers for predicting in which patients this metastasis will occur. DCUN1D1, also known as squamous cell carcinomarelated oncogene, is associated with tumor progression and poor outcomes in NSCLC. The objective of this study was to investigate the role of DCUN1D1 expression in cases of brain metastasis due to NSCLC. Materials and Methods Primary tumor samples from a total of 71 cases of NSCLC, either with (n=40) or without (n=31)brain metastasis, were evaluated for DCUN1D1 expression by immunohistochemistry analysis. Results DCUN1D1 expression was detected in 16 patients (23%) and tended to correlate with T classification (15% of T1-2 tumors vs. 30% of T3-4 tumors, p=0.083). DCUN1D1 expression was significantly associated with tumor stage. It was observed in none of the patients with stage I disease, 10% of those with stage II disease, and 29% with stage III disease (p=0.009). In addition, 14 of 16 DCUN1D1-positive patients resulted in brain metastasis (p=0.01). The odds ratio of brain metastasis for patients with DCUN1D1 expression was 3.112 (p=0.009). Conclusion DCUN1D1 expression may play a role in tumor progression and development of brain metastasis in patients with NSCLC. Evaluation of DCUN1D1 expression may provide assistance in identifying those patients who are at higher risk for brain metastasis.

A Yellow Pigmented Soil Bacterium Producing a Polysaccharide of High Viscosity
유진영,정동효,Yoo, Jin-Young,Chung, Dong-Hyo Korean Society of Food Science and Technology 1989 한국식품과학회지 Vol.21 No.3
A strictly aerobic bacterium forming yeller pigment and a highly viscous polysaccharide was isolated. The bacterium was identified as Pseudomonas mendocia. The polysaccharide was presumed to be ${\beta}-glucan$ with o-acetyl group in its structure and the constituent sugar components were glucose and rhamnose in the molar ratio of 2.1: 1.0. The intrinsic viscosity was 64.73dl/g. The apparent viscosity of 1% aqueous solution was 428 mPa.s. at $42\;sec^{-1}$ and the yield stress of the solution was 8.89Pa. The polysaccharide did not have thermal stability but show pH and salt stability. 산업용 다당류의 개발을 목적으로 고점도의 다당류생산 미생물을 토양으로부터 분리하였다. 본 세균은 동정한 결과 Pseudomonas mendocina로 생각되었다. 본 세균이 생산하는 다당류는 o-acetyl기를 함유한 ${\beta}-glucan$으로 추정되며 구성당으로서는 포도당과 람노오스가 몰비로 2.2 : 1.0 구성으로 되어 있고 수용액은 의가소성 유체이다. 1% 용액은 428mPa.s의 점도를 나타내며 항복치는 8.89Pa이다. 이 용액은 열안정성은 없으며 pH 안정성과 염안정성은 있었다. 유동활성화에너지는 6.57 Kcal 이다.

원유로부터 bacteriocin을 생산하는 미생물을 분리하고 이 균주들을 중심으로 Lactobacillus plantarum을 target organism으로 하여 항균력을 비교하였다. 분리된 항균성물질들은 Gram양성 및 음성균에 대하여 넓은 항균 spectrum을 보였으며 선발균주 중 최종적으로 항균력이 가장 높은 1112-1을 우량균주로 선발하였다. 선발한 1112-1 균주의 항균성물질 230IU/㎖ 첨가시에 Lactobacillus plantarum의 생육은 완전히 억제되었으며 500IU/㎖ 첨가시 E. coli의 생육은 대조구에 비하여 11% 억제되었다. 분리된 물질은 단백태 물질로 판단되었고, 아세톤 부분 정제물은 alpha amylase(human saliva), catalase, trypsin, lysozyme 등의 효소에 내성이 있었고, 분자량은 5,900 정도로 추정되었다. 분리된 1112-1 균주는 형태학적으로 2∼6개의 사슬을 만드는 Gram 양성 구균으로서 정상 젖산발효균인 Lactococcus sp.인 것으로 판단되었다. 이 균의 생화학적 특성은 maltose 및 sucrose가 late positive, lactose가 음성, mannitol 및 salicin이 양성인 것이 Lactococcus lactis와 다른 특징이었다. Bacteriocin-producing microorganisms were screened from raw milk and tested their antimicrobial activities against Lactobacillus plantarum ATCC 8014 as target organism. Antimicrobial substances isolated showed broad antimicrobial spectra against Gram positives and negatives. Strain 1112-1 was selected as a test organism due to its highest antimicrobial activity among the isolates. Antimicrobial substance produced by 1112-1 completely suppressed the growth of Lactobacillus plantarum at 230 IU/㎖ and showed 11% growth inhibition of E. coli at 500 IU/㎖ level. The antimicrobial substance was found to be proteinaceous material which was inactivated by carboxypeptidase, elastase, alpha amylase, amyloglucosidase, pronase, protease Ⅳ, alpha chymotrypsin, ficin, cellulase, phosphatase and lipase. The molecular weight was estimated by SDS-PAGE as 5,900. The isolate 1112-1 was identified as one of the related strains of Lactococcus sp. The strain was different from Lactococcus lactis in the following characteristics: late positive in maltose and sucrose fermentation; positive in mannitol and salicin fermentation; negative in lactose fermentation.
