  • The Bio-Inspired System focuses on the creation of an effective system model for massive network applications and is being widely developed. However, the system has a problem-difficulty implementing three features in the system, which includes scalability, adaptability and survivability. To solve this problem, we designed an Ecogent as a multiple intelligence agent, and a Bio-platform to address the three features of scalability, adaptability and survivability. The Bio-Inspired System Platform consists of an ERS (Ecogent Runtime Services) Platform and a Bio-Platform. The ERS platform serves the basic functions of mobile agents, such as Registration, Life Cycle, Migration, Communication, Location and Fault Tolerance. The Bio-Platform includes the functions of Evolution Control and Stigmergy Control to address evolution and adaptation.

  • This study aims at exploring the Eco-generation's perception on public libraries depending on the use of cultural programs. For this purpose, a series of in-depth interviews was conducted with public library users in the Eco-generation in order to investigated the current status of the cultural programs in public libraries and their underlying identity. The results identifies that user experience of library cultural programs did not make a meaningful difference in users' perceptions on public libraries. Furthermore, there was no meaningful difference in the perceptions on cultural programs between public libraries and other cultural organizations. A possible explaining factor to the results based on the interviews and existing research reports was identified as the lack of identity in the library cultural programs. Consequently, further studies on public libraries' identity, cooperation between research and practice in public libraries, discussion with cultural organizations in the library district, and considerations in public policy are suggested in order to strengthen the identity in the library cultural programs.

  • We carried out studies on develop of the ultrasound tissue mimicking materials(TMM) by synthesis of polymer urethane(C, CCR, $TiO_2$, tungsten, graphite, silver type). The major finding were as follows; (1) C type TMM was shown good homogeneity, penetration, gray scale like as liver tissue and propagated speed 1,540 m/s, attenuation $0.5{\sim}0.7\;dB/cm/MHz$. (2) $TiO_2$ type TMM was shown heterogeneous dot echo pattern. (3) Silver type TMM was appear good homogeneous echo pattern like as echo texture of thyroid gland. Therefor, C type TMM will be useful for ultrasound Q/A phantom materials and previous phantom materials.

  • Toxicity of seven environment friendly agricultural materials (EFAM), which have been used in the domestic market were evaluated on honeybee (Apis mellifera) and asian multicolored ladybird beetle (Harmonia axyridis). Three EFAMs made from plant extract agents (Wangjoongwang Eco, Bogum Eco and Bestop Eco) and four EFAMs made from microbial utilizing agents (Worldstar Eco, Goodmorning, Bluechip and Cameleon) were investigated as EFAMs. In evaluation of toxicity on honeybee, the $RT_{25}$ values of 3 EFAMs made from plant extract agents ranged from 1 to 3 days. Therefore, honeybee should be released 1-3 days after application of these EFAMs. Meanwhile, the four agricultural materials made from microbial utilizing agents did not show any mortality against honeybee. In evaluating the toxicity to adult and larva ladybird beetles, all seven EFAMs made from plant extract agents and microbial utilizing agents to show any mortality.

  • This study has the objective of proposing the basic data for the political and administrative support needs so that the Echo generation can be prepared with the supper-aged society, by verifying the perception level and degree of necessity about the outplacement support service, whether they want to be serviced or not, and necessary contents in the service with the employed people and non-employed people as objects among the Echo generation in the Southeast region. The study result derived from these effort is illustrated as follows. The perception level of the Echo generation about outplacement support service showed to be significantly different according to the gender, age, industry type, and career. The degree of needs was significantly different depending on the age. For the provision period of the outplacement support service, the opinions were that 3 months before the retirement was most appropriate. The intention of participation when the outplacement support service is provided showed to be significantly different depending on the age.

  • Spin echo gradient moment nulling pulse sequences were designed and implemented on a clinical magnetic resonance imaging system. A new technique was introduced for flow compensation that minimized echo time and effectively suppresses unwanted echoes on the slice selection gradient axis in spin echo sequences. A unified gradient shape was used in all orders of flow compensation up to the third order. A dual-purpose gradient was applied for flow compensation and to reduce unwanted artifacts. The sequences were used to generate images of phantoms and/or human brains. This technique was especially good at reducing eddy currents and artifacts related to imperfection of the refocusing pulse. The developed sequences were found to have shorter echo times and better flow compensation in through-plane flow than those of the previous models that were used by other investigators.

  • Various industrial sectors have formally turned to Green Development, practicing eco-design with the goal of saving the environment. Such trend can also be applied to jewelry design and production. Jewelry, which emerged with the birth of humankind, has been a contributing factor to environmental pollution and depletion of resources due to mass production and reckless consuming patterns of the 20th century. With the arrival of the World economic crises, however, the consumption of jewelry has dropped and now the industry desperately needs a boost for revival. In this paper, we propose a way to recycle waste materials and turn them into a new kind of jewelry. We introduce various junk materials that can be reused, and how to reuse them. The new type of jewelry we aim for is environment-friendly, low-cost, and unique as opposed to identical mass production of the past. The eco-design product will likely add new value to jewelry industry. The product targets sophisticated modern consumers with conscientious, environmentally aware consuming patterns. To fulfill the needs of these consumers, we propose methods of upcycling from junk to jewelry, by combining precious stones with waste materials.

  • 초음파학적 검사에 따라 미만성 저에코 영역, 낭포, 다병소성 낭포 및 비후된 피막 등 비정상적 소견을 보이는 전립선에서 추출한 전립선액과 생검조직에서의 LDH 분획비(LDH I/V)의 평균치는 각각 $0.92{\pm}0.55$, $2.69{\pm}0.82$, 정상군(각각 $0.23{\pm}0.20$, $0.57{\pm}0.36$)에 비하여 유의성(p<0.01) 있게 높았다. 세포병리학적 검사에서 전립선 비대증 및 전립선염으로 나타난 비정상군($2.76{\pm}0.77$의 생검조직 LDH 평균분획비는 정상군($1.38{\pm}1.19$)에 비해 유의성 있게 높았으나 전립선액에서는 분획비의 유의차가 인정되지 않았다. 배양결과에 따른 전립선액 및 조직시료의 LDH 분획비는 정상군과 비정상군 사이에서의 유의성은 인정되지 않았다. 결론적으로 저에코 영역 및 낭포부위는 생검조직과 전립선액의 배양 및 세포병리학적 검사에 따른 비정상성 및 높은 LDH 분획비와 밀접한 연관성을 보였다. 특히 경직장 초음파상에 나타나는 미만성 저에코 영역은 전립선 비대증 및 만성 전립선염 등과 같은 병적 관련성을 내포하고 있는 것으로 사료된다.

  • Much energy is consumed up when making a concrete. And especially, because lots of $CO_2$ is discharged for combination material, cement, we are making efforts in order to get lid of this negative thought. Recently, much interest is given to manufacturing eco concrete which is environment friendly and its' application. We should study manufacturing of the concrete whose environment friendly performance should be improved as consistent development concept in order for various approaches to be settled down our country such as lowering of environmental load, utilization of industry wastes and improvement of environment related performance. This study inquired into utilization possibility through from various tests results after manufacturing eco type mixed concrete whose purpose is to lower environmental load in which cement and aggregates can be replaced with metakaolin which is natural material and copper slag which is industry by product.
