  • Microparticle and micropolymer retention and drainage aid systems are powerful tools for paper and board making on a variety of machines. Drawbacks attributed to the current systems sometimes include; apparent high cost, production and quality problems and in some cases a negative effect on formation. The next generation multi-component organic/inorganic systems have demonstrated their ability to decouple the effects of retention and drainage and to improve the formation and print quality for the same retention and in some cases higher retention levels. It is now possible to optimize independently retention, drainage and formation effects with the same high return on investment of current microparticle systems.

  • The aim of this study is to shed light on the importance of female drivers, study their characteristics and needs, and create automobile designs in accordance with the study. The power of female consumers is greatly increasing in a modern society, To the extent that women became the core consumers. Companies are now turning their attention to female consumers in order to survive the fierce competition in the saturated markets. Moreover, it is becoming imperative for companies to actively develop products and services in female perspectives to meet the diversified needs of consumers. It is forecasted that vigorous research, analysis and understanding of the unique culture of women will be increasingly important now that women are emerging as core consumers. Only the companies that makes such efforts consistently can dominate the market. The automobile industry is not an exception. The world's major automobile companies including Volvo and Ford Motor Co. are keenly focusing on automobile exterior and interior designs for women. Korean companies are also designing cars that cater to women, starting with Lanos and Juliet of Daewoo Motors in 1998, yet specific and systematic research on the subject has not been made. This study aims to emphasize the power of female users, make a research and analysis on their needs and characteristics, and suggest car interior designs that cater to them.

  • To find the optimum extraction condition of dried omija, central composite experimental design having three independent variable (extraction temperature, extraction time and water ratio) with five levels was conducted for response surface analysis. The maximum of soluble solid was predicted to the extraction conditions of over 25 fold water ratio, $7{\sim}8hr$ and $75^{\circ}C$. Total acid, total phenol, reducing sugar and vitamin C were predicted to respectively 30 fold water ratio, 6 hr, $70^{\circ}C$, 30 fold water ratio, $6{\sim}7\;hrs,\;80^{\circ}C$ and 30 fold water ratio, $6{\sim}8\;hr,\;80^{\circ}C$, 25 fold water ratio, $5{\sim}6hr,\;80^{\circ}C$ extraction condition. Turbidity of extraction condition. Turbidity of extraction condition was 7 over 25 ford water ratio and over $60^{\circ}C$. From the superimposing results of response variables, the optimum extraction condition was predicted 25 folds water ratio, 6 hr and $65{\sim}70^{\circ}C$.

  • 우리나라는 홍수조절이나 통제를 목적으로 10개의 다목적댐을 통한 홍수방재시스템을 운영하고 있다. 다목적댐 또한 방류능력과 저류능력에 한계가 있기 때문에 안정적인 홍수조절을 위해서는 유입량과 유출량을 미리 예측할 수 있어야 한다. 하지만, 강수량은 그 변동이 심하여 정확한 예측이 어렵기 때문에 합리적인 하천 구조물의 설계와 홍수예측기술의 발전을 위해서는 강우-유출 해석뿐만 아니라 과거의 수문자료를 사용한 통계적인 분석이 요구된다. 최근 기후변화로 인해 과거에 겪지 않았던 이상 기후현상이 빈번하게 나타나고 있다. 기상청발표에 따르면 최근 10년간(1996~2005) 15개 지점의 평균 연강수량은 1,458.7 m로 약 10 �時貂� 하였고, 특히 여름철은 18 %로 증가폭이 가장 크며 호우일수는 30년 평균이 2일인데 비하여 2.8일로 0.8일 증가하였다. 이러한 강수량 및 호우일수 증가는 여름철 심각한 수해를 초래할 수 있다. 본 연구는 기후변화로 인한 수해를 대비하여 홍수기중 저수지 제한수위운영의 안정성을 검토하였다. 연구 대상 지역은 광교저수지로 수원천 상류부인 경기도 수원시 장안구 연무동에 위치한다. 유역면적은 10.98 km, 유효저수량은 250.0 만$m3$이며, 현재 예비취수원으로 사용되고 있다. 기후변화에 따른 하류지역의 예상치 못한 홍수피해를 사전에 예방하기 위해 광교저수지 유역의 설계 강수량과 설계 홍수량을 산정하였다. 제한수위의 시나리오는 현재 시행중인 제한수위와 만수위를 포함하여 5개로 설정하였다. 설계 홍수량이 광교저수지로 유입될 때 시나리오에 따른 월류량은 웨어공식을 이용하여 산정하였으며 결론은 다음과 같다. 1. 39년간의 최다 일 강수량 자료를 사용하여 100년 빈도의 설계 강수량을 Gumbel 분포법으로 산정한 결과 344.4 mm임을 알 수 있었다. 2. 광교저수지 유역의 설계 홍수량을 SCS 방법을 이용하여 산정한 결과 $216.2\;m^3/s$/s로 나타났으며, 총 유입량은 $301.0\;m^3$/day로 파악되었다. 3. 광교저수지로 설계홍수량이 유입될 때 제한수위 시나리오에 따른 최대 방류량은 EL. 87 m의 경우 $23.1\;m^3/s$, EL. 89 m의 경우$27.5\;m^3/s$ EL. 91.36 m의 경우 $79.6\;m^3/s$, EL. 93 m의 경우 $121.1\;m^3/s$ EL. 95.2 m의 경우 $137.`\;m^3/s$이다. 광교저수지 하류부분의 하천정비기본계획상의 설계 홍수량은 $114\;m^3/s$로 홍수기중 저수지의 제한수위는 EL. 91.36 m이하로 설정하는 것이 바람직한 것으로 판단된다.

  • In this paper, several network algorithms were tested to find an optimal one for telecommunication network design. Algorithms such as Dijkstra's shortest path algorithm, Ford-Bellman's shortest path algorithm, Prim's minimum spanning tree algorithm, and Kruscal's minimum spanning tree algorithm were reviewed and compared in terms of feasibility and resulted network construction cost. Then an optimal algorithm that is most suitable for telecommunication network design was selected. For more specific and quantitative analysis of the selected algorithm, it was implemented to a real telecommunication network construction site. The analyzed results showed that the suggested design method when compared with the conventional one, reduced the network construction cost considerably. The total network length estimated by the conventional method were 5267 meters while the suggested method resulted in 4807 meters. Thus the new method reduced the total network length by 8.7 percent which is equivalent to 97,469,000 Won of construction cost. Considering the frequent telecommunication network constructions, due to new urban developments in the nation, the economic benefit of the suggested telecommunication network design method will be significant. In addition to the construction cost savings, the suggested telecommunication network design procedure possesses several other economic benefits. Since the design procedure can be standardized and automatized, it can reduce the design cost itself and the skill acquirement periods required for new or inapt design crews. Further, due to the standardized and automatized design procedure, any telecommunication network design results can accessed more objectively.
