  • The food functional properties of Pleurotus eryngii cultivated with different wavelengths of light-emitting diode (LED) light were analyzed in this study. The levels of total soluble solids of Pleurotus eryngii increased with all the LED lights, except mixed LED light ($B^*R$, $B^*G$ and $R^*G$). Thirty one kinds of components were detected by analyzing the free amino acids. The total free amino acid contents had a slightly higher tendency in the control group, but the ratios of eight essential amino acids among the total amino acids of Pleurotus eryngii cultivated under all the LED lights, including the blue light (blue, $B^*R$, $B^*G$ and $B^*R^*G^*U$) and the green light, were higher than that in the control group. K was the highest-content of mineral, and Mn was the lowest-content. The Ca content increased through cultivation under all the LED lights, except the blue light, but the Fe content (under the green and $B^*R$ lights), K content (under the red and UV-A lights) and Mg content (under the $R^*G$, UV-A and red lights) increased under the exclusive LED light. The total phenolic compounds increased by cultivation under all the LED lights, except the UV-A and mixed lights ($R^*G$ and $B^*R^*G^*U$). The DPPH radical scavenging activity was also improved by all the LED lights, except the mixed light ($R^*G$).

  • Through USN (Ubiquitous Sensor Network) is collected the patient's vital information in real-time, also information collected will be stored in the DB (Date Base), frequent use hospital saved patient's vital information for DB. Stored in the patient's vital medical information stored in the patients with frequent hospital patient to hospital if the patient's vital information is stored in DB. But, stored location is within hospital server or stored in a PC environment, because If utilize other Hospital existing hospitals will need to request. However, Existing hospital have problem for security, authentication, management, cost, manpower, such as, because other hospitals and the exchange of information does not come easily. So, If has the advantage of the patient and the patient's vital information is stored on mobile devices that you can use as DB. It is important to find information quickly and accurately, in this study, Is A study on mobile circulation loop DB systems for patient-centered serbices.

  • 에너지 저장 시스템(ESS, Energy Storage System)은 주파수 조정을 통한 계통 전력품질 개선, 풍력(WT)발전, 태양광(PV)발전등과 같은 신재생 에너지의 출력안정화, 에너지 저장을 통한 에너지효율화 등의 분야에 적용되고 있다. 특히 주파수 조정(F/R, Frequency Regulation)을 위한 에너지 저장 시스템은 한전의 많은 투자를 통해 활발하게 이루어 지고 있으며, 전국 변전소에 설치되고 있다. 주파수 조정을 위한 에너지 저장 시스템은 주파수 상승 시 계통의 전력을 배터리에 충전하고, 주파수 하락 시에는 배터리에 저장된 에너지를 계통에 공급하여 주파수를 안정화 시키는 역할을 한다. 본 논문에서는 주파수 조정용 에너지 저장 시스템의 변전소 적용 사례에 대해 설명한다.

  • Quality stability of the dried layer Porphyra tenera depending on various light sources, water activities, packaging materials and storage temperatures were investigated by peroxide value and chlorophyll degradation. Major fatty acids of dried layer were 45.7% eicosapentaenoic acid and 13.6% palmitic acid. Quality stability was increased in order of darkness, incandescent and fluorescent increased sharply with the decrease of water activity and temperature, and also improved by the packaging material with strong barriers of water vapor, oxygen and light.

  • Theses studies were conducted to clarify the germinating characteristics of seed treated with different temperature, light, and ($Gibberellin(GA_3)$) to produce the homogeneous seedlings Angelicogigas NAKAI. The results obtained are summarized as follows: Rate and speed of germinating at $25^{\circ}C$ were higher than $15^{\circ}C$and $20^{\circ}C$ by 87.3% and 68.9% and also the required day for germination at 25°C was shortest by 14.1 days. Germination rate at the light condition was 90.7% and that at the dark was 65.7%. Germinating ability of seed stored at $4^{\circ}C$and $-10^{\circ}C$ for 165 days as dried states was 92.0% and 91.3%, while that at room temperature was 50.3%, but the longer storage of seed than 165 days decreased the ability. Gibberellin treatment by 10ppm to seed stored at $4^{\circ}C$ and by 6ppm to seed stored at $-10^{\circ}C$ increased the germination rate more by 20.9% and 31.7% than nontreated seed.
