The Saemaeul Movement, which is the representative national campaign of Korea aimed at the development of local communities, has drawn a great deal of attention from home and abroad and formed an element of Korea``s national brand since 2000. Accordingly, this research was conducted for the purpose of constructing a memorial park in Shindo Village, Cheongdo County, North Kyoungsang Province, which is a home to the Saemaeul Movement. As the Saemaeul Movement is benchmarked by many countries around the world today, this research aims to communicate the spirit and social value of the movement and disseminate its effects of local community development in rural areas through the construction of a memorial park. In this study, the design motive of the memorial park was conceived through the historical review and case studies of the Saemaeul Movement. In parallel, theoretical study was also conducted on design techniques as the basis of this research. In consideration of the characteristics of a technical article, this research was conducted in several phases. In the first phase, the conditions of the site where the park construction was planned were analyzed and the direction of its development was set. In the second phase, the main theme and the basic principles of planning were established, and the contents of the park construction project were devised in detail. In the last phase, a comprehensive plan was established, including a space layout to accommodate activities, facilities and programs to be introduced to the park. The park construction site (106,000㎡) was divided into four zones (memorial zone, historical theme park, education zone and experience zone) based on circulation planning aimed at creating memorial space, and was linked to eco-friendly ecological space in consideration of environmental features. At a time when the Saemaeul Movement is being propagated across the world, the result of this study will help create a place for its memorial and play a pivotal role to boost international movements aimed at promoting co-prosperity across the global village. It will also bear significance as an example of theme-based park construction in a rural area and the invigoration of a local community.

We fabricated very high. speed PIN Photodiode module for the application of high speed optical receiver. OMVPE was used for the growth of InP layer on InGaAs absorption layer. The structure was the combination of mesa and planartype. Fabrication procedure was more complicated than simple mesa or simple planar type structure because we used semiinsulating InP substrate in order to reduce stray capacitance. The results at-5V were as follows : dark current was less than 1nA, capacitance was 0.55pF, and cutoff frequency was above 3GHz, and rise and fall time was about 100ps.

연구목적: 2종의 열가압 도재 (e.max Press, Empress Esthetic)와 법랑질 간의 마모양상을 알아보기 위하여 장석계 도재 및 제 3형 금합금과 비교, 관찰하였다. 연구 재료 및 방법: 열가압 도재 e.max Press, Empress Esthetic 및 금속도재관 제작용 장석계 도재 Cermaco 3, 제 3형 금합금으로 원반형 시편을 제작하고, 상대 마모재로는 발거된 건전한 소구치의 교두를 이용하여 Pin-on-disk tribometer 상에서 마모시험 하였다. 법랑질의 마모량은 마모 전후 치아 시편의 무게 변화를 측정하여 부피로 환산하였고, 도재 및 금합금 시편의 평균 표면 조도와 마모트랙 깊이를 표면조도기로, 마모트랙 폭을 주사전자현미경으로 측정하여 마모 양상을 비교하였다. 결과: 1. 법랑질의 마모량은 Ceramco 3군에서 가장 크고 Empress Esthetic군, e.max Press군, 금합금군 순으로 작았으며, Ceramco 3군과 Empress Esthetic군 사이와, Empress Esthetic군, e.max Press군 및 금합금군 사이에는 유의한 차이가 없었다 (P>.05). 2. 마모시험 후 도재 시편의 평균 표면 조도는 Ceramco 3군, Empress Esthetic군, e.max Press군 순으로 작았으며, Empress Esthetic군과 Ceramco 3군 사이에는 유의한 차이가 없었다 (P>.05). 3. 마모트랙의 깊이는 모든 군 사이에 유의한 차이는 없었고 (P>.05), 마모트랙의 폭은 법랑질 마모량 순서와 동일하게 Ceramco 3군, Empress Esthetic군, e.max Press군, 금합금군 순으로 작았으며, e.max Press군과 Empress Esthetic군 사이 및 Empress Esthetic군과 Ceramco 3군 사이에 유의한 차이는 없었다 (P>.05). 결론: 열가압 도재는 장석계 도재보다 법랑질을 더 마모시키지는 않았다. Purpose: The purpose of this study was to compare the wear characteristics of human enamel opposing 2 heat-pressed ceramics (e.max Press and Empress Esthetic), conventional feldspathic porcelain (Ceramco 3) and type III gold alloy. Material and methods: Intact cusps of extracted premolars were used for enamel specimens. Five disk samples were made for each of two heat-pressed ceramics groups, conventional feldspathic porcelain group and type III gold alloy group. Wear tests were conducted in distilled water using a pin-on-disk tribometer. The amount of enamel wear was determined by weighing the enamel specimens before and after wear tests, and the weight was converted to volumes by average density. The wear tracks were analyzed by scanning electron microscopy and surface profilometer to elucidate the wear characteristics. Results: 1. Ceramco 3 led to the greatest amount of enamel wear followed by Empress Esthetic, e.max Press and type III gold alloy. However, there was no significant difference between Ceramco 3 and Empress Esthetic (P>.05), and there were also no significant differences among Empress Esthetic, e.max Press and type III gold alloy (P>.05). 2. The average surface roughness of e.max Press after wear test was smallest followed by Empress Esthetic and Ceramco 3, but there was no significant difference between Empress Esthetic and Ceramco 3 (P>.05). 3. There were no significant differences among the depth of wear tracks of all the groups (P>.05). The group that showed the largest width of wear track was Ceramco 3 followed by Empress Esthetic, e.max Press and type III gold alloy. However, there was no significant difference between e.max Press and Empress Esthetic (P>.05), and there was also no significant difference between Empress Esthetic and Ceramco 3 (P>.05). Conclusion: Within the limits of this study, heat-pressed ceramics were not more abrasive than conventional feldspathic porcelain.

Splenic abscess is a rare clinical condition with a reported incidence of 0.14 % to 0.70 % in various autopsy series. Primary tuberculosis of the spleen as a cause of splenic abscess is even rarer, especially in the antitubercular era. Infants and children have a higher predisposition to extra-pulmonary tuberculosis than adults and tend to develop severe extra-pulmonary disease such as miliary tuberculosis and meningitis. The diagnosis of tuberculosis in infants and children can be difficult because of nonspecific symptoms and clinical findings. Computed tomography establishes the diagnosis of splenic abscess and demonstrates the number and location of abscesses. Splenectomy is the standard of care in most clinical setting. We present a 4-year-old girl who had multiple tuberculosis splenic abscesses and was treated successfully with splenectomy.
