We fabricated textured Ag substrates for YBCO coated conductor and evaluated the effects of annealing temperature on microstructural evolution, texture formation, and surface morphology. Ag ingot, as an initial specimen, was prepared by plasma arc melting(PAM). Subsequently, the ingot was cold rolled to 100 ㎛ thick tape and annealed at temperatures of 600-800℃. The texture and surface morphology of the substrate were characterized by pole-figure and atomic force microscopy(AFM) profile, respectively. It was observed that a strong {110}<110> texture was formed after annealing and its symmetry improved as annealing temperature increased. The full-width at half-maximum(FWHM) of {110}<110> pole was as sharp as 10° for the substrate annealed at 800℃. On the other hand, it was found that the thermal grooving and faceting became remarkable as annealing temperature increased : root-mean-square(RMS) roughness of the substrate annealed at 800℃ was 39.2 ㎚. The substrate of strong texture and smooth surface, fabricated in our study, is considered to be suitable for use as a substrate for the epitaxial deposition of superconductor film.

This paper aims to examine the import pattern of Gwangyang port. The empirical work outlined here uses monthly data running from 2000M1 to 2007M6. All variables are in log form, which are obtained from the Korea International Trade Association and the Korea National Statistical Office. The major commodities that Gwangyang port imports include mineral fuels, metals, transportation equipments, agricultural products and iron and steel. We apply the Ordinary Least Squares to the model consisted of the income variable, the exchange rate, and the seasonal dummies. We find that all of income coefficients have positive signs, but some of exchange rate coefficients are insignificant or positive. This paper also shows that the most of the income coefficients of Gwangyang's major import items tend to increase as the time passes, but the effects of exchange rate are mixed up. The influence of the exchange rates tends to get strength in the items such agricultural products, transportation equipments, and chemical products, while the exchange rate effect decays in the mineral fuels and iron and steel products.

민관 파트너십 중심의 지역개발과 중재집단의 역할 - 피츠버그 기술센터 오염부지 재활용 사례를 중심으로 -

임준형,명성준 한국자치행정학회 2014 한국자치행정학보 Vol.28 No.4

본 연구는 미국 피츠버그시의 브라운필드 재개발사업 사례를 통해 오염부지 재개발과정을 살펴보고, 개발사업에 주요한 영향을 미치는 사건 및 정책행위자를 찾고 이들의 역할을 고찰하는 것을 목적으로 한다. 피츠버그 기술센터 사례는 사용되지 않은 오염된 철강공장 부지를 정화하고 연구개발에 종사한 기술관련 회사들이 입주하는 산업단지를 건설하였다. 당시 Murphy시장은 이 지역에 오랫동안 관심을 가졌던 정치인으로서 적극적인 리더십을 발휘하였다. 아울러 쇠락해가는 지역을 부흥시키기 위해 설립된 피츠버그 도시재개발공사는 개발과정에 적극적으로 참여하며, 개발에 필요한 각종 연구는 물론 이해관련자들간의 갈등 중재 등의 역할을 수행하며 민관협력 방식으로 개발사업을 주도해나갔다. 상충되는 연방정부와 지방정부의 법제도, 다양한 주민 의견 및 배경, 이해관련자들간의 갈등과 같은 오염부지 재개발 사업이 가진 내재적 어려움을 극복하는데 도시재개발공사 및 정치적 리더십이 중요한 역할을 담당하였다. This paper conducts a case study about a brownfield redevelopment project in Pittsburgh, PA, USA. The case study is to observe how the project is proceeded and to define the roles of key events and policy actors during the process. The city of Pittsburgh built the Pittsburgh Technology Center by cleaning-up an old abandoned industrial site which is filled with toxic chemicals from old steel mills. Contributing factors include the active leadership from Mayor Murphy and the role as a coordinator of Urban Redevelopment Authority. Urban Redevelopment Authority led the public-private partnership approach, taking active part in development process and negotiating a diversity of actors with differing opinions. The Authority played crucial roles in overcoming discrepancy between federal and local regulations, differing opinions of citizens, conflict among stakeholders.

사회적 가치의 공동창출과 이해관계자의 통합

연구 목적 - 본 연구는 이해관계자가 자신과 다른 고객을 위한 공동창출을 통해 사회적 가치를 어떻게 창출하는지 규명한다. 방법론 - 대화, 접근성, 위험 및 투명성을 초석으로 강조하는 Prahalad & Ramaswamy(2004)의 DART(dialogue, accessibility, risk and transparency) 모델을 이용한다연구결과 - 본 연구는 이해관계자들이 산출물(제품과 서비스)이 아닌 결과(솔루션과 경험)를 추구함에 따라 가치창출이 이해관계자들 간 서비스 교환의 결과로 간주되어야 한다는 점을 밝힌다. 시사점 - 가치는 혜택이며, 특정 행위자의 후생 수준의 향상을 의미하기 때문에 가치는 항상 수혜자에 의해 공동창조된다. 이것은 사회적 가치가 CSR 활동을 통해 이해관계자에게 전달되는 것이 아니라 사회적 관행을 통해 이해관계자와 공동 창조된다는 프레임워크에 기초한다는 것을 시사한다. Purpose - The purpose of this study is to investigate how stakeholders create social value through co-creation for themselves and other customers. Design/Methodology/Approach - This study employs DART(dialogue, accessibility, risk and transparency) model where Prahalad and Ramaswamy emphasize on dialogue, accessibility, risk and transparency as founding stones. Findings – This paper shows that stakeholders should regard value creation as the result of service‐for‐service exchanges among them since they pursue outcomes (solutions and experiences) not outputs (products and services). Research Implications – Value is a benefit, an increase in the well‐being of a particular actor and therefore value is always cocreated and defined by the beneficiary. This indicates the framework based on the idea that social value is not delivered to stakeholders through CSR activities, but rather cocreated with stakeholders through social practices.

Twisting된 Bi-2223 선재의 제조, 미세조직 관찰 및 임계 특성평가

임준형,지봉기,박형상,주진호,장미혜,고태국,이상진,하홍수,오상수 한국전기전자재료학회 2000 전기전자재료학회논문지 Vol.13 No.3

We fabricated Bi-2223 multi-filaments superconductor tape and evaluated the effect of twisting on the microstructural evolution and critical current. Twist pitches of the tapes are in the range of 70- 8mm and uniformly deformed. It was observed that grain size and the degree of texture decreased as decreasing pitch probably due to the formation of the irregular interface between Ag and filaments. In addition critical current of the tapes decreased to 6.5 A with decreasing pitch to 8mm, showing 48% of degradation compared to the untwisted tapes decreased to 6.5 A with decreasing pitch to 8mm, showing 48% of degradation compared to the untwisted tape(12.5 A). These reduction of critical current may be related to the interface irregularity smaller grain size worse texture and the presence of cracks due to the induced strain during twisting processing.

Recently, the proportion of single-person households is on the increase in Korea, expected to reach 34.6% in 2035. Among the single-person households, Young single family households are facing greater difficulties due to high house prices in Korea. The government is expanding its support to Young single family, executing various policies such as public lease housings, private lease housings for youth, youth dormitory, etc. The purpose of this study is to understand the exact housing requirement of Young single family households who have different lifestyles with other age groups and provide base line data for youth house planning which will be in use later on. Study methods are shown below. First, this research studied the status and characteristics of Young single family households by looking into literature. Second, by studying previous studies concerned with life style and housing preferences of youth, the tool for investigating preferences and needs of housing environment by Young single family households was composed. Third, survey on characterstics of space usage, preferences and needs on flat composition, and preferences of interior design were conducted based on lifestyle of Young single family-households. The survey was conducted as an online survey using SNS for 150 Young single family holds from the age of 20 and 39, including students and office workers from December 2018 to January 2019. The results are as following. (1) Looking into the space usage characteristics, considering that various activities other than basic functions take place in bedroom and living room of small-sized Young single family households, we need to consider this additionally when planning the housing. (2) Looking into the preferences and composite needs of flat composition, the subjects demand separate bed room and more living room space, and also demand expansion of living room space where various activities take place and additional storage such as dress room in bed room (3) The preferences toward interior design show preferences toward modern style and achromatic color, a representative color. The subjects also prefer floor finishing materials normally used for living spaces, and indirect, soft lighting that uses wall. Also, there are differences between interior design preferences between students (20's) and office workers(30's) due to their different lifestyles. Research is needed to propose practical residential environment requirements and plans through a case study of actual public rental housing and a wider range of users. 최근 우리나라 1인가구의 비중은 점차 증가하고 있 으며 이는 2035년에 들어서는 34.6%로 증가할 것이 라 예측되며 이들 중, 우리나라 높은 주택가격으로 인 하여 청년층 1인가구는 더 많은 어려움에 직면하고 있 다. 정부에서는 청년 주거지원을 확대실시하여, 공공지 원 임대주택과 민간 청년임대주택, 청년 기숙사 공급 등 다양한 정부정책을 펼쳐 나가고 있다. 본 연구의 목적은 다른 연령대와 라이프스타일이 다른 청년층 1 인가구의 정확한 주거요구를 파악하여 향후 보급될 청 년 주택 계획 방향을 위한 기초자료를 제공하는 것을 목적으로 한다. 이를 위한 연구방법은 다음과 같다. 첫째, 문헌고찰을 통해 청년층 1인가구의 현황과 특 성을 파악하였다. 둘째, 청년층의 라이프스타일과 주 거선호 관련 선행연구 고찰을 통하여 청년층 1인가구의 주거환경 선호 및 요구에 대한 조사도구를 구성하 였다. 셋째, 청년층 1인가구의 라이프스타일을 바탕으 로 한 공간사용특성과 평면구성 선호 및 요구, 실내디 자인 선호에 대한 설문조사를 실시하였다. 조사는 2018년 12월에서 2019년 1월 초까지 학생과 직장인을 포함한 20세에서 39세 사이의 청년층 1인 가구 150명 을 대상으로 SNS를 이용한 온라인 설문조사를 실시 하였다. 연구결과는 다음과 같다. ⑴ 공간사용특성을 살펴본 결과, 작은 면적인 청년 1인 주거에서 침실과 거실이 기본적 기능 외 다양한 생활이 이루어지는 장소로 계획시 이에 대한 추가적 고려가 필요함을 파악하였다. ⑵ 평면구성 선호 및 요구를 살펴본 결과, 별도의 침실과 거실 공간 확보를 요구하며, 다양한 활동이 이 루어지는 거실공간에 대한 확장요구와 침실공간의 드 레스룸 등의 수납 추가 요구가 있음을 알 수 있었다. ⑶ 실내디자인 선호를 살펴본 결과, 모던스타일과 대표적 컬러인 무채색계열 색채를 선호함을 알 수 있 었다. 그리고 주거공간에 일반적으로 사용되는 마감재 료를 선호하며, 조명은 간접조명 및 벽면을 이용한 은 은한 조명을 선호함을 알 수 있었다. 또한 청년층 내 에서도 라이프스타일 특성에 따른 학생과 직장인의 차별적 실내디자인 선호 특성을 살펴볼 수 있었다. 향 후 실제 공공임대주택의 사례분석과 사용자 범위확대 를 통하여 실질적인 주거환경니즈와 계획방안 제안을 위한 연구가 필요하다.

As the income gap between worker households and non-worker households in Korea gradually widens, the purpose of this study is to identify differences in consumption patterns between worker households and non-worker households. By estimating the error correction equation, it was found that both worker households and non-worker households have small error correction coefficients for communication, health, and food expenses, and in particular, the adjustment speed of communication and health expenses is small, so they experience considerable difficulty in adjusting communication and health expenses. The error correction coefficients of worker households are larger than those of non-worker households in food, clothing, shoes, housing, transportation, and education, so expenditure adjustments are made quickly. However, the error correction coefficients of worker households are smaller than those of non-worker households in communications, entertainment, food, lodging, and non-consumption expenditures, so expenditure reductions are more likely to occur for non-worker households. It is revealed that adjustments are made more slowly compared to maternal households. In particular, the speed of adjustment in non-consumption expenditures for non-working households is much greater, showing that working households are taking a much more cautious approach to reducing spending for retirement. Moving regression analysis shows that the increase in expenditures for items excluding health and food expenses tends to gradually decrease, and while the non-consumption expenditures of working households gradually increase, the non-worker households gradually become smaller, leading to worker households becoming self-employed due to retirement anxiety. It is revealed that they are preparing more than before.
