This research was studied to find out the best ingredients for making demi-glace sauce, using the thickening agent with glutinous rice, non-glutinous rice, brown rice, and black rice, and to look into the quality characteristics. The moisture of demi-glace sauce depending on the thickening type was that the roux added cereals was higher than the control. In addition, it was increased depending on the extension of the storage time. The control was the highest on pH and acidity. On variation depending on the storage time, all of the experimental groups showed decrease on pH. Demi-glace sauce with brown rice and black rice roux showed increase of acidity. The DPPH radical was not tended to be decreased in the experimental group, but it was rapidly decreased in the control, depending on the extension of the storage time. Demi-glace sauce with non-glutinous rice was the highest on Hunter's color L value and generally increased according to the storage time. Also demi-glace sauce with glutinous rice was the highest on 'a' value and 'b' value but was decreased according to the storage time. The control was highest on viscosity, and demi-glace sauce with non-glutious and black rice roux were low on the variation of viscosity depending on the storage time. Increment of total bacteria in demi-glace sauce with black and brown rice roux was relatively lower than the control on storage stability test, and demi-glace sauce with brown rice roux got the highest point after swallow, taste and overall of sensory evaluation.

This study attempts to analyze factors that influence the level of career indecision for prospective librarians. To this end, an empirical study was conducted on the students from the department of Library & Information Science at universities located in Seoul, Kyunggi and Choong Chung Areas. Exogenous variables included personal, organizational and institutional characteristics. The result of analysis using the Structural Equation Model reveals that personal characteristics of students affect the level of career indecision whereas organizational and institutional characteristics do not have any statistical significance in career indecision. This suggests that, in order to raise the career decision level of prospective librarians. there is a need to develop programs to enhance occupational ego-identity and self-efficacy and to provide organizational and institutional supports, including better curriculum, improved practical ability and qualifications as librarians. This study also discusses its limits and areas for future research.

Except The Bronx, 4 boroughs of New York City are islands surrounded by Hudson River, East River, Harlem River, New York Bay and Long Island Waterway. Through industrialization, almost waterfronts in New York City were used for manufacturing and transportation. Post-industrialization beginning, the change of waterfront's function becomes a major issue in NYC's urban planning and urban design. This study considered the characteristic of the urban waterfront redevelopment cases in Lower Manhattan. The result shows that urban waterfront redevelopment plans of diverse scales have been developed, being related strongly one another 'regional scale(NYS) - urban scale(NYC, Manhattan) - community scale(redevelopment projects)', and now, urban waterfront in Lower Manhattan is being transformed into a contact point between water and human as well as public space, a green corridor linking an area to area, and a mixed-zone combining urban area with nature.

The purpose of this study was to evaluate the appropriateness of the replacement time intervals of 18 gauge peripheral intravenous catheters (PICs) by investigating the development of phlebitis. Methods: The subjects were 200 hospitalized patients over 18 yrs old aged who have 18 gauge PICs placed for surgery. After the insertion of PICs, the researcher monitored the insertion site daily for 96 hours for any signs of phlebitis. Results: Phlebitis developed in 25.7% of patients. Patients who developed phlebitis were significantly older and were receiving fluids with faster infusion rate. However, patients with and without phlebitis were not different by gender, insertion site, fluid osmolality, or pH of drugs administered. The incidence rate of phlebitis was higher than 10%(12.9%) starting 24~48 hours after the insertion of 18 gauge PICs. Conclusion: It is recommended to replace 18 gauge PICs within 24~48 hours after insertion. Close monitoring of the PICs insertion site for the signs of phlebitis is recommended.

Purpose: This paper proposes a defect prediction method using digital twins that may overcome the defect detection limitations arising from model-based and data-driven approaches. Methods: To apply the digital twin concept to LCD products, we propose a procedure for the fabrication and validation of digital twins. The crosstalk defect, which is one of the major LCD defects, can be predicted using the developed digital twin. Virtual experimentation conducted based on that were carried out to identify and validate the control parameters. Results: Using the digital twin of LCD products, it was possible to review the process’ CTQ selection adequacy and control specifications. Additionally, by applying the CTQ data of the process to the digital twin, the occurrence of crosstalk defects became predictable. Conclusion: It has been confirmed through case studies that the defect prediction method using digital twins can be effectively applied to the manufacturing industry. Further research on the diversification of defect prediction, digital twin production tools simplification, and real-time connection system of process CTQ data may be conducted.

Urban waterfront could be noticed as a symbolic place realizing sustainable development which pursues the balance of preservation & development, because the very one of major issues of urban waterfront is the balance of preservation of ecological environment and supply of urban land. Just at the right time the new millennium begins, quite a few global cities redevelop urban waterfront to make a model of sustainable urban community in the 21st century. The purpose of this study is to investigate the main subject matter how to balance the opposite concept of ecological environment preservation and urban development in urban waterfront. Among the new millennium's urban waterfront (re)development projects, Greenwich Millenium Village(GMV) in London and Southeast False Creek(SEFC) in Vancouver were selected to cases, because they respectively represent Urban Village and New Urbanism, the theories and campaigns of community planning & design based on ESSD(Environmentally Sound & Sustainable Development). As a result, the cases have common themes; mixed-use development in land use, transit-oriented development in transportation, and restoration, preservation, expansion and connection of biotope in environment, and besides, social mix, sustainable energy, etc. And, both cases never construct new communities, damaging the existing ecological environment of urban waterfront. On the contrary, they first restored the polluted waterfront environment and later, permitted urban (re)development very limitedly to minimize environmental damage & environmental pollution. That's to say, they put environmental preservation first, and then meet the needs of urban functions & urban activities by creating compact, complex and intensive urban system. And also, there’s one other notable point. In both cases of GMV and SEFC, the main principal of urban waterfront (re)development is 'public benefit - publicness'. They understand very well that urban waterfront is very important ecological resource and public space of all citizens, and they make waterfront parks for all citizens, improve access to waterfront by walk, bicycle, bus, subway, etc, for anyone to access to waterfront easily & enjoy urban waterfront, and supply a lot of public rental houses as well as many types of condominiums, for a variety of people different with income, job, social level, life style. etc, to live together. Finally, the cases of GMV and SEFC show that they realize the environmentally sound and sustainable development, turning a polluted waterfront to a good urban place based on 'public benefit - publicness'.

무선랜에서 스트리밍 서비스를 위한 새로운 고속 핸드오프 알고리즘의 설계 및 구현

최정희(Jung-Hee Choi),민상원(Sang-Won Min) 한국통신학회 2011 韓國通信學會論文誌 Vol.36 No.1

본 논문에서는 무선랜 시스템에서 이동 중에도 seamless streaming 서비스를 지원하기 위한 고속 핸드오프 알고리즘을 제안하였다. 기존의 무선랜 시스템에서 핸드오프 동안 seamless streaming 서비스를 지원하지 못하게 되는 문제점이 있기 때문에 이를 해결하기 위해 핸드오프 시작을 결정하는 임계값을 주변 무선 환경에 맞추어 자동으로 조정하는 알고리즘을 제안하였다. 제안된 알고리즘은 불필요한 스캐닝 동작을 하지 않으므로 핸드오프 지연시간을 줄일 수 있다. 또한 특정 채널 군만을 스캐닝 하는 능동적인 스캐닝 과정을 통해서 핸드오프 지연 시간을 줄일 수 있다. 기존의 무선랜 시스템에서 이루어지는 핸드오프 과정과 제안한 고속 핸드오프 알고리즘을 적용한 시스템과의 비교 시험을 통해서 제안한 방식의 핸드오프 성능이 향상됨을 확인하였다. We have considered fast handoff algorithms to support seamless streaming in wireless LANs. It is impossible to provide seamless streaming service while moving within wireless LANs, In this paper, we proposed a new handoff algorithm where the critical value for handoff can be adjusted according to peripheral wireless circumstances. This algorithm can prevent an unnecessary scanning job and save handoff delay time through the active scanning procedure to the specific channel groups. Also, we evaluated the handoff performance of our proposed algorithm, and compared it with the performance of the existing wireless LAN. We can see that the performance with our proposal is better than that of the general wireless LAN.
