The purpose of this study was to find the changes in the habitat of wild birds caused by climate change in urban rivers and protected areas that greatly require ecological functions. In the future, this study can be used as a management index to protect the urban river ecosystem and maintain the health of sustainable urban rivers, thereby ensuring biodiversity. The Tancheon Ecological and Landscape Conservation Area, selected as a target site, has been affected by climate change. The four seasons of Korea have a distinct temperate climate, but the average annual temperature in Seoul has risen by 2.4-2.8℃ over the last 40 years. Winter temperatures tended to gradually increase. Precipitation, which was concentrated from June to August, is now changing into localized torrential rain and a uniform precipitation pattern of several months. Climate change causes irregular and unforeseen features. Climate change has been shown to have various effects on urban river ecosystems. The decrease in the area of water surface and sedimentary land impacted river shape change and has led to large-scale terrestrialization. Plants showed disturbance, and the vegetation was simplified. The emergence of national climate change indicator species, the development of foreign herbaceous plants, the change of dry land native herbaceous species, and wet intelligence vegetation were developed. Wild birds appeared in the territory of winter-summer migratory. In addition, species change and the populations of migratory birds also occurred. It was judged that fluctuations in temperature and precipitation and non-predictive characteristics affect the hydrological environment, plant ecology, and wild birds connecting with the river ecosystem. The results of this study were to analyze how climate change affects the habitat of wild birds and to develop a management index for river ecological and landscape conservation areas where environmental and ecological functions in cities operate. This study can serve as a basic study at the level of ecosystem services to improve the health of urban rivers and create a foundation for biodiversity.

천정환(Jung-Whan Chon),현지연(Ji-Yeon Hyeon),황인균(In-Gyun Hwang),곽효선(Hyo-Sun Kwak),한정아(Jeong-A Han),정윤희(Yun-Hee Chung),송광영(Kwang-Young Song),서건호(Kun-Ho Seo) 한국식품과학회 2010 한국식품과학회지 Vol.42 No.3

V. parahaemolyticus는 국내에서 여름과 가을철에 걸쳐 발생되며 생선이나 패류 등의 해산식품을 날것으로 섭취하거나 불완전하게 익혀 먹을 경우 식중독을 일으키는 병원균이다. 본 연구의 목적은 표준 검출기법인 배지배양법을 이용한 V. parahaemolyticus의 검출과 real-time PCR을 이용한 V. parahaemolyticus의 검출에 있어서 그 유효성과 효율성을 검증하는 것이다. V. parahaemolyticus의 발생기록과 발생가능성이 있는 여러 해산식품과 무순에 적절한 균량을 접종하고 APW로 증균배양하였다. 증균배양이 끝난 후 TCBS선택배지에 배양액을 획선도말하고, 동시에 증균배양액에서 1 ㎖을 채취하여 real-time PCR을 실시하였다. TCBS에서 초록색이 나온 집락을 1-3개 선별하여 TSI 배지에 접종하여 screening test를 거친 후 API 20NE strip을 사용하여 확인동정하였다. 또한 정상세균총이 목적균의 성장과 검출에 어느 정도의 영향을 미치는지 평가하기 위하여 25 g의 식품 내 정상세균총의 수준을 함께 측정하였다. 실험결과, 자체 제작한 real-time PCR서열은 V. parahaemolyticus를 특이적으로 검출할 수 있었고 검출한계는 PBS에서 10³ CFU/㎖ 였다. 또한, 식품 내 정상세균총이 높을 경우 증균배양 시 목적균의 성장에 영향을 미칠 수 있다는 것을 확인하였다. Real-time PCR은 180개의 전체 샘플 중 76개의 양성 결과를 보여 66개의 양성 결과를 낸 배지배양법에 비해 더 많은 양성 검출율을 보였으나 통계학적인 유의차는 발견되지 않았다. Real-time PCR은 표준검출법인 배지배양법과 비교해 볼때 동등하거나 우수한 검출력을 지닌 것으로 보이며 이러한 realtime PCR법은 24시간 이내에 확정동정까지 가능하여 시간과 노동력의 소모가 많은 배지배양법에 앞서 선별검사로 사용할 경우 시간, 비용, 노동력 절감에 매우 유효할 것으로 판단된다. Vibrio parahaemolyticus (V. parahaemolyticus), which is commonly found in raw seafood, causes gastroenteritis in humans. Rapid and effective methods have been developed as culture methods require up to 5-7 days. In this study, real-time PCR was compared with the standard culture method for detecting V. parahaemolyticus in seafood and radish sprout samples. Five hundred grams of the samples were artificially contaminated with V. parahaemolyticus then divided into 20 samples. The samples were incubated in alkaline peptone water and then streaked onto thiosulfate-citrate-bile saltssucrose agar. Biochemical tests for suspicious colonies were performed using the API 20NE strip. In parallel, real-time PCR was performed targeting the toxR gene using the enrichment broth. The real-time PCR was sensitive in discriminating V. parahaemolyticus from other foodborne pathogens. The detection limit of the real-time PCR was 10³ CFU/㎖ in phosphate-buffered saline. Although the real-time PCR detected more positive samples (76 out of 180, 42%) than the culture method (66 out of 180, 37%), there was no significant statistical difference (p>0.05) between the two methods. In conclusion, real-time PCR assays could be an alternative to the standard culture method for detecting V. parahaemolyticus in seafood and radish sprouts, which has many advantages in terms of detection time, labor, and sensitivity.

In this study, the MgO thin-film passivation layer was adopted to protect passive matrix organic light emitting diode(PMOLED) with the cathode separator from moisture and oxygen. Using the substrate rotate and tilt technique during the deposition, the organic and cathode layers were perfectly covered with MgO. And then, we analyzed the difference of the current-voltage and luminescence characteristics between passivated OLED of the MgO and non-passivated OLED. It was found that the number of dark spot generated from the degradated pixel was decreased owing to the Mgo thin-film passivation layer using the tilt & rotate technique. And the half-life time passivated OLED was improved two times more. Thus, the MgO could be vaccum-deposited under the low temperature and had a merit that the organic layer was not much affected. We can consider that MgO thin film passivation method can be adopted to protect the OLED from moisture and oxygen and can offer the enhancement of lifetime.

김훈,김광호,김재경,이윤희,한정인,도이미,주병권,Kim, Hoon,Kim, Kwang-Ho,Kim, Jae-Kyung,Lee, Yun-Hi,Han, Jeong-In,Do, Lee-Mi,Ju, Byeong-Kwon 한국전기전자재료학회 2003 전기전자재료학회논문지 Vol.16 No.1

In this study, the inorganic thin-film passivation layer was newly adopted to protect the organic layer from moisture and oxygen. Using the electron beam evaporation system, the various kinds of inorganic thin-films were deposited onto the organic layer and their interface properties between organic and inorganic layer were investigated. In this investigation, the MgO layer showed the most suitable properties, and based on this result, the time dependent emission properties were estimated for the OLED with and without passivation layer. In this experiment, we can see that the time-dependent emission properties of MgO passivated OLED had longer life-time compared to non-passivated OLED. Therefore, we can consider that the MgO thin film is one of the most suitable candidates for the thin-film passivation layer of OLED.

IEC 61850 기반의 변전소자동화 시스템을 구축하기 위해서는 실계통 변전소에서 엔지니어링이 가능한 IED 공통의 엔지니어링 툴 개발이 요구된다. 따라서 본 연구에서는 해외 선진사가 지원하는 시스템 및 SCL 구성 툴과 같이 IED 상호간의 통신분석 및 운영관리에 요구되는 IED 통합 엔지니어링 툴을 개발하고자 한다. 본 연구에서 개발된 IED 통합 엔지니어링 툴은 IEC 61850에서 규정하는 XML 기반의 언어로 작성된 ICD, SCL 및CID 파일을 생성, 편집 및 저장할 수 있는 프로그램이다. 특히 IEC 61850 기반으로 국내에서 개발된 IED에 대한 엔지니어링 작업 등 모든 IED에 적용이 가능한 범용적인 툴로써, IED에 대한 신뢰성 검증과 사용자 중심의 편리함과 효율성을 제공할 수 있다는 장점을 갖고 있다. In order to construct the IEC 61850 based substation automation system, the IED integration engineering tool is necessary to cope with the substation automation by full digital devices in the real power system. Compared the configuration tools provided IED vendors which are able to support the operation and communication analysis among IEDs, the XML based IED integration engineering tool can build, edit and save the ICD, SCL and CID files. Particularly, the IED integration engineering tool is possible to apply the IEC 61850 based IEDs to engineering the systems and also provides the reliability and efficiency of the system to the utilities and manufacturers.

COG용 Solder Bump 제작을 위한 Ni 무전해 도금 공정에 관한 연구

한정인,Han, Jeong-In 한국재료학회 1995 한국재료학회지 Vol.5 No.7

LCD 모듈을 위한 실장 기술인 Chip on Glass 공정 기술을 개발함에 있어 구동 IC와 기판d의 Al 전극을 연결하기 위하여 기존의 기술과의 연관성 및 공정의 연속성, 제조단가등을 고려하여 Pb-Sn 범프를 사용하고자 하였으며 이를 위해 Al 금속 박막위에 니켈 무전해 도금하는 방법을 연구 하였다. Al 전극에 무전해 니켈 도금하기 위해서는 광레지스트 차폐막을 손상하지 않는 전처리 방법이 필요하기 때문에 전처리 방법으로서 알칼리 아연산염 처리법과 불화물을 이용한 아연산염 처리법을 선택하여 실시하였다. 이 가운데 산성불화암모늄(NH$_4$HF)을 1.5 g/$\ell$ 함유하고 황산아연(ZnSO$_4$)을 100 g/$\ell$ 함유한 산성 아연산염 용액에서는 광레지스트 차폐막이 손상되지 않았으며 처리시간을 적절히 조절함으로써 알루미늄 박막상에 선택적으로 니켈 무전해 도금을 할 수 있었다. 아연산염 응액중의 첨가제와 무전해 도금액 중의 억제제인 Thiourea는 도금층의 평활도를 높이는 역할을 하였다. 또한 아연산염 처리를 하기 전에 산세 처리를 함으로써 도금층의 균일성을 향상시킬 수 있었다. To connect the driver IC and Al coated glass, a method has been developed to plate electrolessly Ni on Al/PR system. It Is necessary to pretreat Al to remove oxide film before plating. In order to find pretreatment process which does not damage photoresist or glass, alkaline and fluoride zincate process have been investigated. Because photoresist and aluminum thin film can easily dissolve in alkaline solution, it is considered that the fluoride zincate process was a suitable one. After immersion in the zincate solution containing 1.5 g/$\ell$ ammonium bifluoride and 100 g/$\ell$ zinc sulfate, electroless nickel plating could be performed. The additive in the zincate solution and thiourea in the plating solution increased smoothness of the plated surface. Acld dip could improve the uniformit of the surface.
