유럽에는 '이탈리아의 캄포디멜라에 가서 살면 적어도 85세까지는 보장된다'는 말이 있다고 한다. 캄포디멜라는 이탈리아의 수도 로마에서 남쪽으로 약 150km 떨어진 곳에 있는 작은 마을이다. 지도를 찾아보니 캄포디멜라에서 가장 가까운 역은 이트리(Itri)역이다. 캄포디멜라에 가기 위해 오전 9시 45분에 로마의 중앙역인 테르미니역에서 포미아(Formia)행 기차에 몸을 실었다. 기차가 출발한 지 한 시간 반 만에 이트리역에 도착했다.

Organosilicone-based surfactants consist of hydrophobic organosilicone groups coupled to hydrophilic polar groups. Organosilicone surfactants have been widely used in many industrial fields starting from polyurethane foam to construction materials, cosmetics, paints & inks, agrochemicals, etc., because of their low surface tension, lubricity, spreading, water repellency and thermal and chemical stability, resulted from the unique properties of organosilicone. Especially, trisiloxane surfactants, having low molecular weight organosilicone as hydrophobe, exhibit low surface tension and excellent wettability and spreadability, leading to their applications as super wetter/super spreader, but have the disadvantage of vulnerability to hydrolysis. A variety of trisiloxane surfactant structures are required to provide the functional improvement and the defect resolution for reflecting the necessities in the various applications. This review covers the synthetic schemes of reactive trisiloxanes as hydrophobic siloxane backbones, the main reaction schemes, such as hydrosilylation reaction, for coupling reactive trisiloxanes to hydrophilic groups, and the synthetic schemes of the main trisiloxane surfactants including polyether-, carbohydrate-, gemini-, bolaform-, double trisiloxane-type surfactants.

Asynchronous Transfer Mode-Passive Optical Network(ATM-PON) Technology is one of the best solutions for implementation of broadband access network. In this paper, we propose a new Dynamic Bandwidth Allocation (DBA) algorithm for ATM-PON systems. The DBA is a key technique for data traffic management. DBA has been studied widely to allow ATM-PON to transport data traffic cost-effectively and efficiently, and currently a hot standardization issue in Full Service Access Network(FSAN) and ITU-T. The proposed DBA algorithm efficiently manages the user traffics according to their service categories. Performance of the proposed algorithm, in aspect of Cell Transfer Delay(CTD) and Cell Delay Variation(CDV), is evaluated using computer simulation.

In this study, the strength stability of an LPG mini tank with a storage capacity of about 250 kg was analyzed by FEM. According to the results of the FEM analysis, it is preferable that the corner radius of the LPG mini tank having a storage capacity of 250 kg is designed to be 175 to 205 mm. Generally, the larger the corner radius of the end plate of the gas storage tank, the higher the safety of the strength, but the volume or capacity of the tank is reduced. Therefore, it is important to derive the optimum design data. Further, in order to securely design the strength of the gas tank, the thickness of the tank is designed to be thick. However, when the thick steel sheet is used, the material and the transportation costs are increased. The result shows that it is preferable to select the optimum thickness of the steel sheet from 4.5 to 5.5 mm. Using the level gauge type of column on the central axis of the gas tank, the safety strength of the LPG tank can be enhanced as much as twice, compared with the tank of the existing level gauge to measure the liquid level by piercing the side wall of the tank.

Linear feature such as lines and curves are one of important features in image processing. In this paper, new method of linear feature detection is suggested. Also, we have studied approximation technique which transforms detected linear feature into data structure for the practical. This method is based on graph theory and principle of this method is based on minimal spanning tree concept which is widely used in edge linking process. By postprocessing, Hairs and inconsistent line segments are removed. To approximate and describe traced linear feature, piecewise linear approximation is adapted. The algorithm is demonstrated through computer simulations.

정자의 아크로좀에 존재한다고 알려진 효소들중 실온에 방치할 경우 또는 완충용액으로 정자를 세척할 경우 쉽게 아크로좀 막으로부터 흘러나옴을 관찰하였다. 신선하게 사용된 토끼의 정액을 $0^{\circ}C$에서 트리스 완충용액에 방치할 경우 하이얄유로니데이스는 39%정도가 유출되어 나오고, 또 $37^{\circ}C$에서 1시간 더 둘 경우 나머지 30%, 그리고 두시간째에 17%가 방출되며, 계면활성제로 아크롬을 처리할 경우 단 4%의 효소가 추출되었다. 다른 두 탄수화물 분해요소인 베타 엔 애시틸글루코사미니데이스 및 베타 그룩유로니데이스도 하이얄유로니데이스처럼 쉽게 분리되어 나오고 계면활성제로 추출될 수 있는 양은 대단히 적었다. 이와같이 효소가 아크로좀에서 방출되는 정도에 따라 아크로좀막에 흡착된 정도를 알 수 있으며 동시에 수정과정에서 역활을 이해하는데 도움이 될 것이다.

Mobile device, one of typical devices in ubiquitous environment, is received attention owing to portability. In these days, technical researches on a kind of the device are focusing on applications of smart phone. For example, the techniques using geographical position and applied instances such as augmented reality techniques are gradually increasing. That makes data processing important. Mobile application services for users also require various application techniques based on moving objects. In addition, they require the techniques that processed data are needed to be shown in visualization. However, this is reality that it lacks of showing visualization works to improve the understanding of thing what it is. To reduce or solve the problems, in this paper we show the results to implement the R tree based 3 dimension index architecture in visualization. Further, we implemented and present creating objects, showing in 3D for the objects, catching spatial position on a node map through mini map function and improving the understanding of R tree by visualizing.
