박말영,임은성,박지영,노지현,추은영,유재연 한국의료QA학회 2009 한국의료질향상학회지 Vol.15 No.2

문제: 환자가 수술장내에서 수술을 기다리면서 느끼는 불안감을 최소화할수있도록해야하지만수술실의 효율성 및 의료진 편의성 위주로 운영되고 있어 수술실 내 대기시간이 연장되고 있다. 목적: 수술장내 대기시간을 단축시키기 위해 수술환자의 이동경로에 따른 지연요인과 문제점을파악하고 개선하여 환자가 수술을기다리면서 느끼는 불안감을 최소화하고자 한다. 의료기관: 부산시에 소재한 481병상의 종합병원 수술실 질 향상 활동: 수술환자의 대기시간 지연요인과 문제점을 파악하고 개선을 통해 질 향상을 도모하였다. 개선효과: 대기시간 수행율에서 수술장 도착까지의 수행율이 개선전 95%에서 개선후98%로, 수술방입실까지의 수행율이 개선전 88%에서 개선후 94%로, 마취시작 까지의 수행율이 개선전 93%에서 개선후 96%로 수행율이높아졌다.

최근 국내에서도 사회 주체(주민, 사용자 등) 주도형 혁신모델이자 지역·현장기반형 혁신의 장으로서 리빙랩이 도입·적용되고 있다. 본 연구는 지역사회문제 해결을 위한 실험으로 ‘리빙랩’을 명시하고 추진된 북촌 리빙랩, 성대골 리빙랩, 건너유 프로젝트 3개 사례를 분석하였다. 각 사례의 지역문제, 문제해결 목표, 참여주체 및 주체별 역할, 리빙랩 추진체계, 의의를 분석하고 리빙랩의 유형·특성을 도출했으며, 향후 발전 방안을 모색하였다. 분석 결과 각 사례는 기술 활용 방식과 사용되는 기술의 특성은 차이가 있으나 과학기술·ICT와 지역문제 해결을 연계하고자 했으며 지역주민이 문제 발굴부터 기술 실험 및 확산·적용까지 리빙랩 전반에서 주도적인 역할을 수행하였다. 또한 공통적으로 중간지원조직의 역할이 리빙랩 운영에 중요한 요인으로 작용하였다. 각 사례는 서로 다른 리빙랩 유형을 보이고 있는데, 북촌 IoT 리빙랩은 정부/지자체가 리빙랩 활동기반 조성 또는 행위자 활동을 지원하고 프로젝트 형태로 운영된 반면, 성대골 에너지전환 리빙랩과 건너유 프로젝트는 시민사회 스스로 지역문제를 해결하기 위해 문제를 정의하고 기술을 탐색하는 형태로 진행되었다. Living Lab is being introduced and applied as an innovation model driven by social entities (residents, users, etc.) and as an innovation place based on local and field. This study analyzed three living lab cases of Bukchon IoT living lab, Seong-Daegol energy transition living lab, and Daejeon Geonneoyu project, which were designated as "Living Lab" to solve local problems. We analyzed the local problem, the problem solving goal, the role of each participant and the subject, the living lab promotion system, the significance in each case. In addition, the types and characteristics of living labs were elucidated and future development plans were discussed. The result is as follow. First, each case has a tendency to link science technology and ICT with local problem solving though there is a difference between the technologies used. Second, local residents played a leading role in the whole living lab process from problem identification to technical experimentation, diffusion and application. Third, the role of the intermediaries commonly played an important role in the operation of the living lab. Last but not least, each case has different types of living lab. Bukchon IoT living lab being operated as a project by the government / municipality to create a living lab activity-base or to support actors’ activities. On the other hand, the Seong-Daegol energy transition living lab and Daejeon Geonneoyu project were conducted by the civil society itself to define problems and explore technologies in order to solve local problems.

바이오매스에서 유래된 2,5-dihydroxymethylfuran(DHMF)을 KMnO4 산화반응으로 furan-2,5- dicarboxylic acid(FDCA)를 합성하였다. 합성한 FDCA와 다이올류를 에스테르화 반응과 축중합 반응을 진행시 켜 폴리에스터를 중합하였다. 폴리에스터는 NMR을 통해 조성을 분석하였고 DSC와 TGA를 통해 열적특성을 분 석하였다. 합성된 폴리에스터의 고유점도는 0.78∼1.2 dL/g으로 상용화된 poly(ethylene terephthalate)(PET) 와 비슷하였다. 다이올의 길이가 증가할수록 Young`s modulus와 strength는 낮아지고 elongation-to-break는 높아지는 경향을 확인하였다. 합성한 poly(ethylene furandicarboxylate)(PEF)의 Young`s modulus는 3551 MPa, strength는 103 MPa로 상용화된 PET와 비슷하였다. Furan-2,5-dicarboxylic acid (FDCA) was synthesized by KMnO4 oxidation of 2,5-dihydroxymethylfuran( DHMF) derived from biomass. Polyesters were synthesized by esterification and polycondensation of FDCA with various diols(ethane-1,2-diol, propane-1,3-diol, butane-1,4-diol, hexane- 1,6-diol, decane-1,10-diol). The composition of polyesters was characterized by using 1H NMR. Thermal properties of the polyesters were characterized by DSC and TGA. Intrinsic viscosities(IV) of the polyesters were measured to be 0.78∼1.2 dL/g comparable with IV of commercial poly(ethylene terephthalate)(PET). As the chain lengths of diols increased, Young`s modulus and strength decreased and elongation-to-break generally increased. Young`s modulus and strength of the polyesters were measured to be 3551 MPa and 103 MPa, respectively, comparable with commercial PET.

A Shih-tzu(8-year-old, castrated male) was referred to the Veterinary Medical Teaching Hospital of Chungnam National University with the history of relapsing pruritus, recurrent dermatitis. On the physical examination, generalized erythema, otitis externa, alopecia and lichenification were observed. Using Favrot's criteria for diagnishing atopic dermatitis, 7 criteria were satisfied out of 8 criteria. After treatment for infection, intradermal skin test was performed(positive allergen : Df, Dp). And then immunotherapy was performed, but clinical signs were not getting better. Next treatment of glucocorticoid shown little improvement of clinical signs, and adverse effect(diarrhea) was shown after cyclosporine application. So application of leflunomide which is used for human atopic dermatitis treatment in some case was planned. After 6 months of application of leflunomide, clinical signs were decreased gradually.

증권시장에서 판매원 윤리의식의 결정요인

지성구,이감용,윤영진 한국유통정보학회 2001 유통정보학회지 Vol.4 No.1

This research addresses the determinants of salespeople's ethical awareness(SEA) in stock market. The suggested model include several factors such as environmental uncertainty(volatility and diversity), customer orientation, ethical climate and perception of the ethical awareness of supervisor. Some hypotheses that show the relationship between SEA and the factors are suggested. To attain these objective of this research, samples from salespeople were collected. For the analysis of data, reliability test, validity test, correlation analysis, multiple regression analysis and frequency analysis were used with SPSS WIN package. the results show that environmental volatility, customer orientation(3 factor, 1 factor), organization's ethical climate, affect SEA, however, environmental diversity and customer orientation(2 factor, 4 factor) don't work. And, as hypothesized, SEA generally had positive impacts on customer relationship quality(customer's trust and satisfaction).

Poly(ρ-phenylenesulfide)와 Poly(ρ-phenylene)으로부터 제조된 탄소의 리튬 이온 2차전지 anode 재료로서의 전기화학적 특성

유덕영,이주성,박수길,변지형,류신환,정윤이 한양대학교 에너지·환경기술연구소 1998 에너지·環境技術論文集 Vol.4 No.-

Poly(p-phenylenesulfide)와 poly(p-phenylene)으로부터 제조된 탄소를 리튬이온 2차전지용 음극재료로 사용하여 전기화학적특성을 연구하였다. 이들 고분자들을 질소 분위기하에서 승온속도 2℃/min로 1000℃까지 상승시킨 후, 1시간 동안 탄화시켜 탄소를 제조하였다. Poly(p-phenylene)으로부터 제조된 탄소가 보다 더 규칙적인 구조를 가지기 때문에 Poly(p-phenylenesulfide)으로부터 제조된 탄소보다 더 많은 용량과 충방전 효율을 나타내었다. 수산화리튬과 염화주석(Ⅱ)을 첨가하여 용량의 증가와 충방전 효율의 증가를 가져올 수 있었다. 이중에서 poly(p-phenylene)에 염화주석(Ⅱ)을 첨가시켜 제조된 탄소가 가장 큰 충방전 용량과 충방전 효율의 향상을 가져왔다. Carbon inaterials manufactured from poly(p-phenylene sulfide) and poly(p-phenylene), were studied on electrochemical characteristics as anode materials for lithium ion secondary battery. These polymer precursors were heat treated for 1hr at 1000℃ with the rate 2℃/min under nitrogen atmosphere. Carbon manufactured from poly(p-phenylene) showed higher capacity and coulomb efficiency of charge/discharge than carbon from poly(p-phenylene sulfide) because the former has better ordered structure. Carbon manufactured from polymer precursors adding stannous chloride or lithium hydroxide showed higher capacity and better efficiency of charge/discharge. Also, carbon manufactured by adding stannous chloride to poly(p-phenylene) showed the highest capacity and efficiency of charge/discharge.

SNMP 기능확장을 통한 Network 성능 향상에 관한 연구

유성진,김중태,조영주,정일용 조선대학교 전자정보통신연구소 2003 電子情報通信硏究所論文誌 Vol.6 No.1

On internet environment multimedia information containing voice and image is tramitted, which is tens times or hundreds times larger than oridnary information Analytic types for network management in this environment are consisted of a real time analysis, a basis analysis and an intensive analysis. An intensive analysis is to gather trend information on specific objects periodically, and to analyze this information in order to monitor network conditions When SNMP is applied to collect the trend information, it brings on an increase of network load, a delay of response time and a decrease of accuracy of data collection since an agent responds to each managers' polling. In this paper, an efficient SNMP is proposed and implemented to add time variables in the existing SNMP PDU It minimizes unnecessary traffic at an intensive analysis between manager and agent, and collects trend information accurately The results of experiments show that it has compatibility with the existing SNMP, decreases an amount of network traffic greatly and increases the accuracy of data collection.
