박테리오 파이지 K11 lysozyme은 최근에 우리 실험실에서 클로닝 되었으며, 숙주균주의 세포벽을 분해하는 고유의 lysozyme활성과 박테리오 파아지 K11 RNA 중합효소의 전사반응을 억제하는 활성을 가지고 있는 것으로 확인되었다. 이미 잘 연구된 박테리오 파아지 T7 lysozyme의 경우 클로닝되고 분리 정제된 T7 lysozyme 단백질의 3차 구조 및 T7 RNA 중합효소와의 결합양상에 대하여 밝혀졌다. 따라서 우리 실험실에서는 K11 lysozyme과 K11 RNA 중합효소와의 결합 정도 및 그 특성을 파악할 목적으로 yeast two hybrid 시스템을 통하여 K11 RNA 중합효소와 K11 lysozyme의 단백질-단백질 상호작용을 알아보고자 하였다. LexA 시스템을 이용하여 LexA DNA 결합 부위를 갖고 있는 pLexA에 K11 lysozyme 유전자를 삽입하여 prey로 하였따. 활성 부위로는 B42 융합 단백질을 만드는 pJG4-5에 K11 RNA 중합효소의 결합은 생체 밖에서 reporter 유전자인 lacZ와 leu2의 발현으로 확인되었으며 이들의 결합정도와 결합부위에 대한 연구들은 진행중에 있다. Recently phage K11 lysozyme was cloned and characterized in our lab. The K11 lysozyme was identified to have dual functions. It not only cuts a peptidoglycan bond in bacterial cell wall but also acts as an inhibitor of K11 RNA polymerase. It has been known that the T7 lysozyme binds specifically to T7 RNA polymerase and inhibits transcription. The dual activities of K11 lysozyme are atreeable to the case of T7 phage lysozyme and RNA polymerare. In order to identify the binding magnitude of K11 lysozyme with K11 RNA polymerase, yeast two-hybrid system was used. K11 phage lysozyme gene was introduced into pLexA plasmid and used as a prey. Also, K11 phage RNA polymerase gene was introduced into pJG4-5 and used as a bait. The binding between K11 lysozyme and K11 RNA polymerase was demonstrated by expression of reporter genes such as lacZ and leu2.

연구배경: 영양불량은 기저질환 회복에 영향을 미쳐 감염, 호흡부전, 상처치유 지연 등을 통해 환자의 재원기간 연장, 이환율 및 사망율을 증가시킨다. 중환자실 입원 환자의 경우 일반 병실 환자에 비해 영양불량 위험율이 높으며, 영양불량이 동반되어 있는 경우 사망률을 더욱 증가시킬 수 있다. 영양불량은 내분비 기관에 영향을 미쳐 호르몬 불균형을 가져올 수 있으며 이러한 호르몬 불균형은 주로 초기에 일어나는 것으로 알려져 있다. 따라서 호르몬 불균형은 초기영양불량을 잘 반영할 수 있을 것으로 기대된다. 연구목적: 본 연구는 중환자실 입원 환자를 대상으로 호르몬불균형이 초기 영양상태 판정 지표로서의 타당성 여부를 알아보기 위해 시행하였다. 대상 및 방법: 2009년 1월부터 2009년 6월까지 충북대학교병원 중환자실에 입원한 환자를 대상으로 체질량지수, 혈청 알부민, 총 콜레스테롤, 총림프구수를 기준으로 초기 영양상태판정 프로그램을 사용하여 초기 영양상태 판정을 시행하였다. 대상환자는 입원 시 혈액검사, 체중, 신장, APACHE score 측정과 함께 유리갑상선호르몬, 갑상선자극호르몬, 트리요오드 타이로닌(T3), 혈중 코르티솔, 부신피질자극호르몬을 측정하였다. 연구결과: 대상환자는 총 83명으로 구성되었고, 충북대학교 병원 초기 영양상태판정 프로그램을 이용하여 영양 양호군(n=38명), 영양불량군(n=45)으로 분류하였다. 양군 사이에 연령(영양양호군 60.4±17.5 vs 영양불량군 65.5±16.7) 및 성별은 차이가 없었다(영양불량군 F:M=40%:60% vs 영양양호군 F:M=26.3%:73.7%). APACHE score 역시 양군 사이에 차이는 없었다(영양양호군 vs 영양불량군, 19.4±7.8 vs 21.5±8.6). 혈액검사에서 혈청 알부민, 단백질, 총림프구수, 중성지방 수치는 영양불량군에서 영양양호군에 비해 통계학적으로 의미있게 감소하였다. 호르몬 결과에서 혈중 코르티솔, 부신피질자극호르몬, 소마토메딘-C는 양군 사이에서 차이를 보이지 않았다. 트리요오드 타이로닌(T3), 갑상선자극호르몬은 영양불량군에서 영양양호군에 비하여 의미있게 감소하였다(Table 1). 결론: 중환자실 입원환자를 대상으로 시행한 초기영양상태 판정에 따른 호르몬결과에서 영양양호환자와 비교하여 영양불량환자에서 호르몬 불균형 차이점이 관찰되었다. 호르몬 불균형은 영양상태판정에서 효과적인 지표로 사용될 수 있을 것으로 생각된다.

The purpose of this study was to analyze the difference between career decision and career development efficacy of vacational high school students before and after the promotion of secondary vocational education policy considering various school and student variables of students. To do this, the propensity score matching was adapted to KEEPⅠ2006 data and KEEP Ⅱ2016 data that examined the same grade at 10 years gap. The findings of the current study were as follows. Comparing the patterns of change over the decade, the total number of schools and the number of students in academic and vocational high schools in 2006 and 2016 did not show any significant change. However, after 2016, the employment rate of students who graduated from vocational high schools exceeded the entrance rate. In addition, satisfaction with individuals, families, and schools was found to increased after implementation of secondary vocational education policy. As a result of analyzing career education achievement after controlling the difference between these two groups, the career decision and career development efficacy of specialized high school students in 2016 were higher than those of vocational high school students in 2006. In addition, the career capacity of meister high school students were higher than that of the specialized high school students in 2016. Finally, based on the results of the current study, policy implications for the implementation of effective secondary vocational education policies and the direction of subsequent research were discussed. 본 연구는 중등 직업교육 정책 추진 전과 후 시점을 중심으로 직업계 고등학교 학생들의 진로결정 및 진로개발효능감을 학생 개인 학교 가정 변인들을 고려하여 분석하는 데 목적이 있다. 이를 위해 10년간의 격차를 두고 동일 학년을 조사한 한국교육고용패널Ⅰ의 3차년도(2006년) 자료와 한국교육 고용패널Ⅱ의 1차년도(2016년) 자료를 활용하여 연구를 진행하였다. 특히 10년간의 격차를 두고 있는 중등 직업교육 정책 시행 전과 후를 비교 분석하기 위하여 두 집단 간 존재하는 선택 편의의 문제를 해결하며 집단 간 동등성을 확보해주는 경향점수 매칭(propensity score matching) 방법을 활용하여 분석하였다. 분석결과, 10년간의 변화양상을 비교하였을 때 2006년과 2016년의 일반계고와 직업계고의 총 학교 수와 학생 수는 큰 변동을 보이지 않았지만 2016년 직업계고 학생들의 졸업 후 취업률이 진학률을 넘 어서는 결과를 보였다. 또한 중등 직업교육 정책 시행 이전보다 이후의 개인 가정 학교에 대한 만족 도가 증가하는 것으로 나타났다. 이와 같은 집단 간 차이를 통제한 뒤 두 시점별 진로교육 성과를 분 석한 결과, 진로결정과 진로개발효능감 모두 2006년 전문계고 학생들 보다는 2016년 특성화고 학생이 높았으며, 2016년 특성화고 학생들보다는 마이스터고 학생들이 높은 것으로 나타났다. 마지막으로는 이러한 연구결과를 바탕으로 효과적인 중등직업교육 정책 시행을 위한 정책적 시사점 및 후속연구의 방향을 논의하였다.

전현정,김지훈,김원종 한국공업화학회 2015 한국공업화학회 연구논문 초록집 Vol.2015 No.1

Although various anticancer drugs have been developed, their successful treatments are still far off due to the unintended effects on normal cells. Thus, we have developed efficient drug delivery system for cancer therapy by utilizing polymerized paclitaxel(pPTX), beta-cyclodextrin( βCD) and superparamagnetic iron oxide nanoparticle(SPION). Though PTX is a well-known anticancer drug on variable cancers, it has poor solubility in blood. In order to overcome this problem, we employ host-guest interaction between βCD and pPTX. In addition, SPION was utilized for magnetic-guided delivery method which improve drug targeting efficiency. SPION is prepared by using co-precipitation method and polymer-conjugated paclitaxel is developed according to the previously reported method by our group. The drug-conjugated-nanoparticle formation was confirmed and its biocompatibility was evaluated.

Background: Idiopathic Central Diabetes Insipidus in children or adolescents requires a frequent follow-up regimen using serial brain MRI and CSF examinations especially if an isolated pituitary stalk thickening or loss of a hyperintense signal in the posterior pituitary lobe is observed. Although a detailed description has not been made in adults who had Idiopathic Central Diabetes Insipidus, the clinical course of a Central Diabetes Insipidus in children or in adolescents can not be applied to adults because a follow-up study is so invasive and expensive. In this report, we evaluated the clinical course of Idiopathic Central Diabetes Insipidus in adults. Methods: The diagnosis of Idiopathic Central Diabetes Insipidus was based on the presenting clinical symptoms, the water deprivation test, biochemical studies and a brain MRI. We measured the urine specific gravity, urine and plasma osmolarity, electrolytes, and daily urine amount and we also performed an anterior pituitary evaluation. Patients had contrast-enhanced MRI and biochemical studies every 4 to 12 months. Results: The patients included 8 females and 4 males. Their ages ranged from 20 to 76 years and their mean age was 45±17 years. Tumor markers in the CSF were not detected any of the patients. An anterior pituitary evaluation showed that four patients had hyperprolactinemia, and five patients had impaired secretory responses of Growth Hormone to an insulin induced hypoglycemia. Nine of the 12 patients had thickening of the pituitary stalk, seven had lacked the hyperintense signal of a normal neurohypophysis. The abnormalities of MRI disappeared in 3 patients by the 4th, 27th and 36th month follow up periods, respectively. The follow up duration was between 8 months and 11 years 3 months and the mean follow up duration period was 50.6±45.5 months. Clinical symptoms were corrected by DDAVP administration. Other symptoms were absent. Conclusion: In our study, of Idiopathic Central Diabetes Insipidus in adults there were no observed germinomas or other disease that were observed. Therefore this disorder may have a benign course

This study investigated the changes in yields, antioxidant compounds, and antioxidant activities among 11 adzuki bean cultivars cultivated in a paddy field with somewhat poorly drained soil. The adzuki bean cultivars were cultivated in the paddy field from 2015 to 2016 in Milyang, Gyeongsangnam, Korea. Average soil moisture content was 16.5% in 2015 and 31.0% in 2016 at the experimental site during adzuki bean cultivation. As the soil moisture content increased, most of the adzuki bean cultivars showed deceases in stem height, first setting pod node, number of pods, 100 seed weight, and yield. Chungju-pat produced the greatest yields among the 11 cultivars in 2015 and 2016, whereas Hongeon had the smallest yields. Adzuki bean yields after paddy field cultivation was lower for all cultivars than for adzuki bean yields from the same cultivars after upland field cultivation. Chungju-pat and Chilbo-pat showed the smallest decreases in yields after paddy field cultivation, whereas Hongeon and Kumsil showed the greatest yield reductions. There were no significant differences in proximate composition. Some mineral components ($P_2O_5$, Ca, and Mg) were statistically different across cultivars. Chungju-pat had the highest Ca and Mg contents, but antioxidant components (polyphenol and flavonoids) and antioxidant activities (ABTS and DPPH) were highest in Saegil and lowest in Jungbu-pat. PCA and clustering analyses, based on the growth, yield, and antioxidant component measurements, performed to identify which variables contributed the most to separating adzuki bean cultivars or to grouping cultivars with similar characteristics. These analyses showed that the antioxidant components and antioxidant activities had the most influence on grouping cultivars together. Among the 11 cultivars, Saegil was statistically different from the other cultivars, but the other 10 cultivars were not significantly different under paddy field cultivation. Soil moisture content affected adzuki bean yield and antioxidant component contents. An increase in soil moisture led to a decrease in yield, but an increase in antioxidant components. These results provide information that will improve the selection of an appropriate adzuki bean cultivar for use in paddy fields.
