최혜련,박기혁,이재훈 대한혈관외과학회 2016 Vascular Specialist International Vol.32 No.2

Purpose: Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAAs) involving the common iliac artery requires extension of the stent-graft limb into the external iliac artery. For this procedure, internal iliac artery (IIA) embolization is performed to prevent type II endoleak. In this study, we investigated the frequency and risk factor of buttock claudication (BC) in patients having interventional embolization of the IIA. Materials and Methods: From January 2010 to December 2013, a total of 110 patients with AAA were treated with EVAR in our institution. This study included 27 patients (24.5%) who had undergone unilateral IIA coil embolization with EVAR. We examined hospital charts retrospectively and interviewed by telephone for the occurrence of BC. Results: Mean age of total patients was 71.9±7.0 years and 88.9% were males. During a mean follow-up of 8.65±9.04 months, the incidence of BC was 40.7% (11 of 27 patients). In 8 patients with claudication, the symptoms had resolved within 1 month of IIA embolization, but the symptoms persisted for more than 6 months in the remaining 3 patients. In univariate and multivariate analysis, risk factors such as age, sex, comorbidity, patency of collateral arteries, and anatomical characteristics of AAA were not significantly related with BC. Conclusion: In this study, BC was a frequent complication of IIA embolization during EVAR and there was no associated risk factor. Certain principles such as checking preoperative angiogram, proximal and unilateral IIA embolization may have contributed to reducing the incidence of BC.

천연식품보존료의 개발을 목적으로 marta rosemary의 항균활성을 조건을 달리하여 조사하였다. 균주에 따른 에탄올 추출 marta rosemary의 항균성은 S. typhimurium과 B. subtilis에 대하여 높았다. 용매별 항균성은 극성이 작은 butanol과 hexane 추출액에서 높았고. 수용액에서의 항균 활성은 pH 7에서 가장 높았다. 허브의 미생물의 생육억제 양상은 B. subtilis에 대하여 저 농도에서는 유도기 지연형, 고농도에서는 유도기 지연 및 비증 식속도 억제형이었으며 S. typhimurium은 농도에 관계없이 비 증식속도 억제형으로 관찰되었다. 이와 같은 경향은 낮은 pH 에서도 유사하게 나타났다. 항균물질의 $100^{\circ}C$에서의 열안정성은 가열시간이 길수록 허브의 항균력이 저하되었고 $121^{\circ}C$에서 15분간의 열처리로 인한 허브의 항균력은 B. subtilis보다 S. typhimurium에서 높게 나타났다. Antimicrobial activities of ethanol extracts of marta rosemary (Rosemarinus officinalis L.) against Bacillus subtilis and Salmonella typhimurium were investigated under conditions similar to processing of general food materials to develop natural food preservatives. The strongest antimicrobial activities were shown against the tested organisms at pH 7. In B. subtilis, the herbal extract extended the lag phase at low concentrations, and reduced the specific growth rate during logarithmic phase at high concentrations. In S. typhimurium the herbal extract reduced the specific growth rate even at lower concentrations. These trends were obtained at low pHs of culture solution. Antimicrobial substances of herbs were efficiently extracted with low polar solvents. The thermal stability of antimicrobial substances decreased with heating time at $100^{\circ}C$. S. typhimurium was more sensitive to herbal extracts at $100\;and\;121^{\circ}C$ than B. subtilis.

The objective of this study is to decide the relations between the stress from obesity and the self-esteem of children according to whether taking part in the exercise. The subjects of our research were 450 upper-grade students of elementary school. We used the questionnaire of Cho, Yang-Rae (1997) as the tool to measure the stress from obesity, and another questionnaire to measure the self-esteem was what had been corrected and compensated by Kim Hui-Hwa, Kim, Kyeong-Yeon (1998) on the base of Self-Perception`s Profile for children of Harter (1985). We carried out one-way analysis of variance, t-test verification, Pearson correlation coefficient, and regression analysis by using the data collected. As the result of our study, the stress from obesity and the self-esteem of the upper-grade students proved to have the negative correlation, and the stress from obesity and the self-esteem according to whether children take part in the exercise to have the statistically-meaningful differences. For both the boys and the girls, there were the statistically-meaningful differences in the stress and the self-esteem. In conclusion, the meaning of this study consists in reminding that the participation in the exercise, the movement instruction of the children PE leaders, and the right guidance and management for the obesity can play an great role to enhance the self-esteem in the childhood, the developmentally vital age, as participating in the exercise is an important factor to influence the obesity stress of the children.

This experiment began to reveal how college club experiences can bring upon greater happiness and cause a change in an individual`s entire lifestyle. In order to achieve this task, I surveyed 461 college students; asking them questions related to their club experience, position in the club, the character that the club developed, how active one was in the club, the period of time one was active in the club, leisurable satisfaction and their happiness as a whole. These questions were asked to the random sample of college students to measure the reliability and propriety of the students feelings, and to find the average and the range of the different responses that were collected. In order to find out the students` leisure satisfaction of the club, there was a variance and regression analysis to find a deviation from the mean. Furthermore, I had even greater analyses to find the relationship between leisure satisfaction and life satisfaction. The results of this experiment were as follows: the majority of the students that I surveyed showed a great correlation between leisure and life satisfactions. Moreover, there was a great difference in the feeling of life fulfillment in those who held authoritative positions felt a greater difference in their vision upon their lives and that they felt things a bit differently from others that were just members of the club.
