The major objective of this study is to investigate the effects and application of improvement for railway steel plate girder bridge by resilient panel track system. It analyzed the mechanical behaviors of steel plate girder bridge with applying resilient panel track system on the finite element analysis and laboratory test for static & dynamic characteristics. As a result, the improvement of steel plate girder bridge with resilient panel track systems are obviously effective for the static & dynamic response which is non-ballast steel plate girder bridge . The analytical and experimental study are carried out to investigate resilient panel track system decrease vertical acceleration and deflection on steel plate girder bridge for serviceability. And the resilient panel track system reduced dynamic maximum displacements(about 59%) and stresses(about 82%), the increase of dynamic safety is predicted by adopting resilient panel track system. From the dynamic test results of steel plate girder bridge, it is investigated that vertical acceleration and deflection is very low with applying resilient panel track system. The servicing steel plate girder bridge with resilient panel track system has need of the reasonable improvement measures which could be reducing the effect of static and dynamic behavior that degradation phenomenon of structure by an unusual response characteristic and a drop durability.

본 연구는 개화기 경기지역(경기도 관내)의 근대학교의 성립과정과 각급 학교의 실상을 고찰해 봄으로서 한국근대교육사 정립에 일조 하려는데 목적을 두었다. 경기지역에 서구식 근대학교가 처음 설립된 것은 고종29(1892)년 기독교 선교사인 조원시목사의 부인 죤스(Mrs George Heber Jones)에 의해 설립된 인천사립영화여학당이 효시가 된다. 이후 경기도에는 정부와 기독교선교사 및 민족 선각자에 의해 상당수의 근대학교의 설립을 보이고 있다. 경기지역에 설립된 근대학교의 교육이념은 관료양성과 민족주의 정신 및 기독교정신과 민주주의 정신에 기반을 두고 설립주체에 따라 건학정신을 달리하였을 것으로 본다. 그러나 개화기 경기지역에 성립된 근대학교는 통감부의 교육조치에 의해 기존의 관ㆍ공립학교는 그 명칭이 개칭 또는 개편되고, 탄압을 견디지 못한 사립학교는 공립학교에 병합되거나 폐교되는 비운을 맞이하게 되며, 교육이념도 변질되어 공립학교는 친일교육과 동화주의 교육을 추진하는 식민지교육기관으로 전락하게 되었고, 민족사학은 교육구국운동에 진원지가 되었고, 기독교계 사학은 국가사회에 봉사할 수 있는 민족지도자 양성을 위한 교육기관으로 변모하고 있다. The purpose of this study is to inquire into the establishing process of modern schools and their real situations in Keonggi province during the civilizing ages in order to take triangular position in the history of Korean modern education. The western style modern school, Incheon Private Youngwha Women s School, was established for the first time in Keonggi province in the year of 1892, the 29th year of King Ko-jong by Mrs George Herber Jones, Minister Jowonsi s wife. Since that time lots of modern schools began to be established in Keonggi province by government, missionaries, and some national pioneers. It seems that the educational idea of those modern schools might be mainly to produce officials based on nationalism, christianity, and democracy, varying according to their establishing spirit. But those modern public schools were forced to change their school names by the imperial Japanese. Some private schools either became public schools, or were forced to close their school gate. Their educational ideas were forced to change also; public schools cannot but teach pro-Japanese education falling to one of the colonial educational institutes. Some private schools became centers for the save-the nation movement, others for educational institutes to produce national leaders for the development of Korean society.

유사 쉐이더 검색이란 그래픽 디자이너가 원하는 쉐이더와 유사한 쉐이더를 검색하는 것으로 쉐이 더 생성 시 발생하는 시행착오와 시간 낭비를 크게 줄여준다. 본 논문에서는 유사 무늬감 쉐이더 검색을 수행하기 위한 무늬감 추출 방법을 제안한다. 제안하는 방법은 쉐이더들의 특성을 분석하여 쉐이더의 무늬를 결정하는 주요 무늬감 노드를 추출한 후, 추출된 주요 무늬감 노드의 무늬감 특성을 이용하여 쉐이더의 유사 무늬감 검색을 수행하는 방법이다. 실험을 통해 제안하는 방법이 유사한 무늬를 갖는 쉐이더를 효과적으로 검색할 수 있음을 보인다.

Objective: Experimental studies were done to research the clinical effects of Herba Patriniae(HP) aqua-acupuncture (BL13, BL17, BL13·BL17 and free points) on the anti-allergic inflammatory response. Methods: We measured active systemic anaphylatic shock induced by compound 48/80 and microvascular permeability increased by acetic acid. And we measured total IgE and plasma WBC level, serum total protein, albumin, immunoglobulin and NO levels induced by egg albumin. Results: HP aqua-acupuncture pretreatments at all acupoints inhibited active systemic anaphylatic shock induced by compound 48/80 and microvascular permeability increased by acetic acid. Total IgE and plasma WBC level inhibited by HP aqua-acupuncture pretreatment at BL13·BL17 and free points. However, HP aqua-acupuncture didn`t effect serum total protein, albumin, immunoglobulin and NO levels. Conclusion: These results suggest that HP aqua-acupuncture may be beneficial in the regulation of type Ⅰ allergic reaction, but is further required immunological studies on the allergic reaction.

This study was conducted to the evaluate nutritional value of corn taffy residue (CTR), a by-product from Korean traditional taffy, and to investigate the dietary effect of CTR on the yield and composition of milk from dairy cows. Relatively high concentrations of residual enzymes and sugars were found in CTR. Protein and fat concentrations were high, comparable to those of corn gluten meal. Inclusion of 1, 3, and 6% CTR in total mixed rations yielded more milk (p<0.05) than in the control group, and increased milk fat (p<0.05) in high-producing cows (approximately 30 kg). In low-producing cows, (approximately 20 kg), milk yield was increased by 1 and 6% CTR, and milk protein was enhanced by 3% CTR (p<0.05). Based on these results, utilization of CTR is recommended for production of high quality and economical animal products.
