<P>In the present study, we investigated neuronal death/damage in the gerbil hippocampal CA1 region (CA1) and compared changes in some trophic factors, such as brain-derived neurotrophic factor (BDNF), glial cell line-derived neurotrophic factor (GDNF) and vascular endothelial growth factor (VEGF), in the CA1 between the adult and young gerbils after 5 min of transient cerebral ischemia. Most of pyramidal neurons (89%) were damaged 4 days after ischemia-reperfusion (I-R) in the adult; however, in the young, about 59% of pyramidal neurons were damaged 7 days after I-R. The immunoreactivity and levels of BDNF and VEGF, not GDNF, in the CA1 of the normal young were lower than those in the normal adult. Four days after I-R in the adult group, the immunoreactivity and levels of BDNF and VEGF were distinctively decreased, and the immunoreactivity and level of GDNF were increased. However, in the young group, all of their immunoreactivities and levels were much higher than those in the normal young group. From 7 days after I-R, all the immunoreactivities and levels were apparently decreased compared to those of the normal adult and young. In brief, we confirmed our recent finding: more delayed and less neuronal death occurred in the young following I-R, and we newly found that the immunoreactivities of trophic factors, such as BDNF, GDNF, and VEGF, in the stratum pyramidale of the CA1 in the young gerbil were much higher than those in the adult gerbil 4 days after transient cerebral ischemia.</P>

Afferent loop syndrome is an uncommon complication of a gastrectomy and Billroth Ⅱ reconstruction. It may cause symtoms at any time from the first postoperative day to many years after the gastrectomy. Afferent loop syndrome is characterized by abdominal pain, vomiting and elevation of serum amylase. Thus, it is difficult to differentiate afferent loop syndrome from other cause of acute pancreatitis. However, the history of gastrectomy can be an important clue for diagnosing afferent loop syndrome. We experienced one case of chronic afferent loop syndrome with acute pancreatitis. After appropriate management, the abdominal pain disappeared and serum amylase level decreased. We report this case with a review of relevant literatures.

최근 우리나라의 지역개발이나 정책에 있어 과거의 중앙정부 중심, 물적 성장 중심의 개발 패러다임에서 벗어나 자립적 역량강화, 지역 간 연계협력, 융합화 등이 강조되고 있다. 이에 본 연구의 목적은 지방자치제가 실시되었으나 지방의 자치기반이 취약하여 지역간 불균형 발전이 심화되는 가운데, 박근혜정부의 출범과 함께 최근 국내외적으로 변화하고 있는 지역발전의 패러다임에 직면하여 지방분권과 균형발전에 토대를 둔 지역 주도의 자립적 지역발전을 이루기 위한 구체적 방안을 제시하는 데 있다. 이를 위해 시대적 요구와 필요성을 절감하고, 지역적 차원에서 창조경제에 기반한 새로운 지역발전 패러다임으로서 국민대통합과 지역균형발전을 지향하는 「지역순환형 자립발전모델」을 제시하였다. 이는 궁극적으로 국내외 패러다임의 변화를 체계적 이론적 틀로써 통합하고 실질적으로 적용하기 위한 것으로 지역을 중심으로 사람을 키우고, 청년을 살게 하고, 사람이 모이게 하는 것을 의미한다. 이를 달성하기 위한 구체적 전략으로서 선순환 전략과 자립전략을 제시하였다. 첫째, 지역순환형 자립발전의 토대가 되는 자립전략으로서 지역발전의 가치와 목적을 ‘지역역량강화(Competency)’. ‘연계협력(Cooperation)’, ‘융합(Convergence)’의 3C전략을 제시하였다. 둘째, 지역순환형 자립발전을 달성하기 위한 선순환 진흥전략으로서 지역교육 진흥, 지역산업진흥, 지역문화예술진흥, 지역복지진흥, 지역창조와 재생을 제시하였다. 첫 번째 전략은 우수 인재양성을 통한 지역교육 진흥(振興)이다 교육부문 진흥을 통해 우수한 인재를 양성하고 지역에 공급하는 시스템을 구축하는 것이다. 둘째, 일자리 창출을 위한 지역산업진흥(振興) 이다, 즉 산업부문 진흥을 통해 청년일자리 창출 및 역동적 지역창출에 기여하는 것이다. 셋째, 지역문화와 예술 기반 구축 및 역량 강화를 통해 지방문화예술을 진흥해 나가야 한다. 넷째, 지역복지역랑 강화를 위한 지역복지 진흥(振興) 이다. 지역복지 진흥을 통해 지역 복지 예산 및 인프라 구축 등을 통해 서민들이 피부로 느낄 수 있는 복지역량을 강화시켜나가야 할 것이다. 마지막으로 지역창조와 재생을 통해 관련 인프라를 확충하여 국토의 고른 공간 창출을 진흥시켜 나가야 할 것이다. Despite local government efforts for regional change, the local self-government based development is vulnerable to deepening disparities between regions. While confronting the paradigm of the latest changes in national and international development of the region that Park Geun-hye government faces, the purpose of this study is to present concrete plans for achieving self-sustaining regional development based on decentralization and balanced development. To this end, with the demands and needs of the times, “The Self-Supporting Development Model of the Regional Circulation” is proposed which professes national unification and balanced regional development as a new regional development paradigm which is based on the creative economy utilizing the local dimension. Ultimately, this is for integrating a domestic and foreign paradigm shift as a systematic theoretical framework and practically applying that in the field. It intends to accomplish this by educating people in the area, making them live in the area, and gathering people into the area. In order to achieve it, we proposed a virtuous and self-supporting development model. Firstly, for tile self-supporting development of the regional circulation, the 3C strategy-Competency, Cooperation, Convergence, Convergence-is proposed. Secondly, in order to achieve self-supporting development as a strategy for promoting regional circulation, we proposed promotion of regional education, regional industrial development, local cultural arts, and community welfare for the creation and regeneration of the region. The first strategy is through promotion of local education by fostering talented people in the regional area. Secondly, by creating jobs for local industrial development and contributing to the creation of a dynamic region. Thirdly, by empowering the local culture and building up the cultural grounds, through promotion of local art and culture. Fourthly, local social welfare should be promoted through community welfare budgets and appropriate infrastructure in order to strengthen the regional social welfare power. As a result, people will benefit through welfare empowerment. Lastly, enhancing the infrastructure through the creation and expansion in the reproduction of the region. As a result of the effort in making a well-balanced regional development, it is expected a well-balanced space development for the whole country.

강전계하에서 PZT-BYF계의 압전 및 유전특성에 미치는 영향

이영근 한국교통대학교 2014 한국교통대학교 논문집 Vol.49 No.-

The 0.99Pb(Zr0.53Ti0.47)O3-0.01Bi(Y1-xFex)O3 [PZT-BYF(x)] (x=0.0-0.3) piezoelectric ceramics have been synthesized by using a modified conventional solid-state method. The effects of BYF(x) addition on the phase formation, microstructure, and piezoelectric/dielectric properties were evaluated. In addition to these measurements, the piezoelectric voltage constant (g33) and the piezoelectric transduction coefficient (d33×g33) were measured in order to evaluate the essential criteria for an energy-harvesting material. With increasing content of Fe2O3 in the BYF(x) system, the piezoelectric and the dielectric properties were significantly improved. At a sintering temperature of 1,170ºC, the piezoelectric and the dielectric properties of PZT-BYF(x) ceramics showed desirable values; this resulted in a significantly higher transduction coefficient. The compositions of PZT-BYF(0.1), PZT-BYF(0.2), and PZT-BYF(0.3) showed a considerably lower ε33T value, but higher d33 and kp values. Therefore, within the concentration limit of x = 0.1 to 0.3 moles of Fe2O3, the g33 and the d33×g33 values were improved significantly. The maximum transduction coefficient of 20,167×10-15 m2/N was obtained from the composition of PZT-BYF(0.3), while the maximum tip displacement of 7.9㎛ was obtained from MPB composition of PZT-BYF(0.2) under alternative electric field.

이근상,고덕구,채효석,신영호 한국지리정보학회 2003 한국지리정보학회지 Vol.6 No.3

최근 높은 수직정확도를 갖는 항공레이저측량 기술이 개발됨에 따라 이를 이용한 DEM(digital elevation model) 생성, 건물추출, 홍수위험지도 제작, 3차원 도시모델 구축 등의 다양한 연구가 활발하게 수행되고 있다. 본 연구에서는 항공레이저측량으로부터 취득한 원시자료로부터 생성한 해상도별 DEM의 표준편차를 계산하기 위해 점비교법, 등고선비교법 그리고 1/5,000 수치지형도를 활용하였다. 비교결과 점비교법이 등고선비교법보다 낮은 DEM 표준오차를 나타냈으며, 이것은 등고선비교법이 점비교법에 비해 조밀한 격자 연산이 이루어지지 않은 것이 원인으로 파악되었다. 또한 1/5,000 수치지형도는 평균수평거리인 25.4m 이하에서는 점비교법과 등고선비교법에 비해 높은 오차를 보였으며, 25.4m 이상에서는 등고선비교법과 유사한 결과를 나타냄을 알 수 있었다. As airborne laser scanning technique is developed with high vertical accuracy recently, there come many studies on DEM(digital elevation model creation, building extraction, flood risk mapping and 3D virtual city modeling. This study applied point comparative method, contour comparative method and digital map with scale 1/5,000 to calculate RMSE of DEM in according to resolution that was constructed using rawdata being acquired by airborne laser scanning. As a result, point comparative method showed lower DEM standard error than contour comparative method, it is a reason that contour comparative method was not carried out detailed grid calculation for point comparative method. Also, digital map with scale 1/5,000 showed higher DEM standard error than point comparative method and contour method in below 25.4m that is average horizontal distance among contour line, and showed similar result with contour comparative method in over 25.4m.

Each and everything named fashion together with clothes were limited in the boundary of women and men's wear has been slow and narrow in changing speed compared to women's, even there are some differences in accordance time. But maintaining the basic features, men's wear in the latter 20th century has undergone diverse change in the part of materials such as various synthetic fiber, glass, metal, artificial leather and the see-through fabric able to seeing the body wearing the clothes. Therefore, the aim and definition of this study is to present the systematic framework giving help to develop men's wear design newer and more various by considering moulding of materials which existing men's wear could not show up and by grasping material trend of men's clothes in 1990s. The results of the study were summarized as follows : (1) Material containing lustering is categorized as Velvet, Silk, Lustering materials by synthetic fiber and Lustering materials by additional substance. The Velvet generally acknowledged having something to feel womanly image shows the bisexual character coexisting feature of men and women after grafting with men's fashion. The Silk was endowed the role as means of pleasure to express beyond boundary of sex breaking the existing consciousness which men should wear male clothes, not considering differences between men and women. The lustering made by synthetic fiber expressed modern sensitivity aesthetically to the suit. The lustering materials made by additional substance is seen mixed masculine character with womanly character. (2) See-through materials are acknowledged as decadence beauty caused by expanding subjective awareness in beauty. (3) Materials by the sorts of Net is categorized as Lace, Knit The Lace expression seemed to emphases the human liberation of men and women and the humanity from liberation of subjecthood. The Knit can be felt both woman's image and man's image as bisexual image, not raising only one side sex. (4) Elastic materials offered the opportunity to approve exposure in a time when exposure of men's body was not granted ethically. (5) Leather was shown as indication of social status and inferiority and expression of collective resistance against sexual stagnation of men and women.
