장용일,김창성 한국생태환경건축학회 2019 한국생태환경건축학회 논문집 Vol.19 No.4

Purpose: Since 2000, urban regeneration has begun to respond to the urban problems of urban decline and climate change due to changes in industrial paradigm and global warming. The purpose of this study is to suggest the direction of urban regeneration plan from the perspective of green community that responds to complex urban problems. Methods: This study was conducted in two stages: the step of using GIS technique and the application of the importance model according to the type of green community urban regeneration project. First, the index system for deriving the target area was set up and the core indicators were selected. The selected core indicators were applied to the GIS technique to derive the integrated indicators and maps. Second, this study tried to re-establish the area as a type of urban regeneration project and to suggest the direction of planning by applying the importance model. Results: As a result of this study, 8 urban areas were derived to cope with the problems of the complex city. The eight urban areas were re-adjusted into 4 urban regeneration projects and the direction of urban regeneration from the perspective of green community was suggested.

녹색커뮤니티 계획요소와 도시재생 사업유형 간의 중요도 분석 및 적용

Purpose: Responding to the urban decline of industrial countries in the West began in earnest in 1980. As the 2000s, urban decline was recognized as a new urban problem with climate change problems due to global warming. The direction of urban regeneration plan that this study is going to approach together with urban decline and climate change. This approach suggests the direction of establishing a new urban regeneration plan through the relationship between green community urban planning elements and types of urban regeneration projects. Method: We conduct a professional consciousness survey as a research method. First, we use the 9-point scale for the top planning elements(Planning Sector) by urban regeneration project type to obtain the average of importance (W = Σw/107: weight). Second, we use the five-point scale to find the significance (P = Σp/107: scoring) of the importance of the sub-planning elements by business type in each upper planning sector. Third, WP = Σw/107 * Σp/107 is calculated, and an average of each importance between business type and planning elements is analyzed. Result: According to the importance between the calculated planning elements and the business type, each business type was intended to present the direction of the plan along with the appropriateness review.

통영 굴 양식장에서 발생하는 스티로폼 폐부자 해양쓰레기 문제의 개선 방안을 찾기 위해 어민들의 의견을 제도분석틀을 통해 분석하였다. 그 결과 양식장은 공유지의 비극이 발생하는 공유자원의 특성을 주로 가지고 있지만, 관련된 법과 정책은 이런 특성에 알맞지 않기 때문에 문제가 지속되는 것으로 분석되었다. 또한 이 문제와 관련된 이해관계자들의 이해(理解)와 이해관계(利害關係)가 다양하고 상이하여, 적절한 대응 정책 개발을 위한 대화와 합의가 힘든 것으로 보인다. 정부는 2017년부터 친환경부표를 보급하기 위해 보조금을 지급하고 있지만, 면담한 어민들은 이 정책에 대한 부정적인 의견을 나타냈다. 또한 어민들은 폐부자의 불법적 투기에 대한 체계적인 감시와 관리를 바랬는데, 이는 공유자원 관리 이론과도 일치하며, 계류 중인 어구관리법안의 취지와도 일치한다. 환경 문제를 더 넓은 범위에서 파악하고 해법을 제시하는 제도분석틀이 실제 정책 개발에서도 더 많이 활용될 필요가 있다. In order to find solutions of marine debris problems of used styrofoam buoys from oyster aquaculture farm in Tong Yeong City, fishermen`s opinion was analyzed through Institutional Analysis and Development Framework. It was analyzed that the problem has continued because the law and policy does not fit to the aquaculture farm, of which physical attributes are mainly those of the common pool resources, where the tragedy of the commons typically happens. In addition, the communication and consensus among the stake-holders to develop proper countermeasures is difficult because their understanding and interest are diverse and different. While the government began to subsidize `environment-friendly buoys`, the interviewed fishermen showed negative opinion to this policy. Moreover, the fishermen wanted systematic monitoring and management of illegal dumping of used buoys, which coincides with theory of the common pool resources management and with the purpose of the pending Law to Manage Fishing Gear. The Institutional Analysis and Development Framework needs to be used in developing government policy more often, as it is useful to understand an environmental problem with wider viewpoints and to find its solutions.

장용삼(Jang, Yong Sam) 한국지적학회 2010 한국지적학회지 Vol.26 No.1

본 연구에서는 세계에서 높은 주택가격수준을 유지하고 있는 서울, 동경, 런던, 뉴욕의 주택시장을 대상으로 각 주택시장 구조적 변화 여부를 통계적으로 검증하고 주택시장에서 발생하는 시장 초과수익률을 통해 각 주택시장의 특성을 파악하는 것을 연구목적으로 하였다. 분석결과를 살펴보면 CAPM모형을 이용한 분석결과, 서울은 다른 3개 도시에 비해 위험도가 큰 반면 런던은 낮은 위험도를 가지고 있는 것으로 나타났으며, 젠센의 알파에 의한 분석결과에서도 4개 도시 중 투자자산으로 부동산을 선택했을 경우 가장 좋은 성과를 나타낸 나라는 영국의 런던으로 나타났다. 또한, 4개 도시 주택수익률의 구조변화 시기를 통계적으로 검증해본 결과, 서울은 1998년, 동경은 2002년, 뉴욕은 1991년, 런던은 1993년에 자산가격하락의 충격으로 각 주택시장에 구조변화가 일어난 것으로 나타났다. This paper examines whether there was any structural change in the housing market of 4 cities; Seoul, Tokyo, London and NewYork which retain the highest housing price of the world. And we analyze the characteristics of each housing markets through the market excess returns. The results suggests the greater risk in Seoul Housing Markets compared with other 3 cities, but the least risk in London Housing Market by Capital Asset Pricing Model, and it also suggests the highest performance in London Housing Market of all 4 cities when applying Jensen Alpha method. And then, the results suggests that the structural changes occurred to housing market of London in 1993, of NewYork in 1991, of Tokyo in 2002, of Seoul in 1998 from the shock of dropping housing price

숙의민주주의의 새 모델: 전남 순천의 지역 교육 활성화를 위한 ‘정담회(情談會)’

장용창 대한지방자치학회 2022 한국지방자치연구 Vol.24 No.2

Since October 2018 to the present (2022), deliberative democracy conferences, named 'Friendly Conversation Meetings' have been held every month in Suncheon City, Jeonnam Province, with citizens and stakeholders interested in local education. This meeting can be considered successful as it has been held regularly and for a long time (longer than 3 years), attracting citizens‘ voluntary participation and influencing local government policy. A survey was conducted to find out which elements of deliberative democracy was the best implemented and which element was the most important for the success, and a focus group interview was conducted to find out what was the background of such success. The survey respondents of 109 citizens assessed that 'diverse participants' was the most important, and 'boosting local education' was the best implemented, among 8 elements of deliberative democracy. At the focus group interview, the people who had the central role in designing and implementing this deliberation program answered that four backgrounds were important: human capital, social capital, the way the meeting was managed, and the independence of the management organization. This ’Friendly Conversation Meeting' seems to be an efficient model of deliberative democracy as it needs small amount of budget and it can achieve the goal of deliberative democracy. 2018년 10월부터 현재(2022년)까지 전남 순천시에서는 지방 교육에 관심 있는 시민들과여러 다양한 이해관계자들이 매월 ‘정담회’라는 이름의 숙의민주주의 토론회를 열어 왔다. 이 정담회는 정기적이고 장기적으로(3년 이상) 지속되었으며, 시민들의 참여를 이끌어내고, 정책에도 영향을 주고 있다는 점에서 성공적이라 볼 수 있다. 이 토론회에서 숙의민주주의의 요소들 중 어떤 것이 가장 잘 실행되고, 어떤 요소들이 가장 중요했는지를 설문으로 조사하고, 그런 성공의 배경이 무엇이었는지를 포커스 그룹 인터뷰로 조사하였다. 2022년 1월에 실시한 설문에 응답한 109명의 시민들은, 설문된 8가지 요소들 중 다양한이해관계자의 참여가 가장 중요했고, 지역 교육 활성화라는 요소의 실행도가 가장 높았다고 평가했다. 이 숙의 프로그램을 기획하고 실행하는 데 핵심 역할을 했던 사람들은 인적자본, 사회 자본, 회의 운영 방식, 운영 조직의 독립성 등의 네 가지 배경이 중요했다고답했다. 이런 정담회는 예산이 적게 들면서도 숙의민주주의의 목표를 달성할 수 있다는점에서 매우 효율적인 모델인 것으로 보인다.

벡터오차수정모형을 이용한 REITs와 금융자산과의 실증연구

장용삼(Jang, Yong-Sam) 한국주거환경학회 2010 주거환경(한국주거환경학회논문집) Vol.8 No.2

The purpose of this paper is to estimate the volatility, the interactions of cause and the effects in major economic level variables through Granger Casualty Test and to grasp the casual relation by using Vector Error Correction Model in the sample period from January of 2004 to December of 2007. And we examine the dynamic movement between the return of Korea Real Estate Trusts and the return of other assets. Variables in the model are statistically significant Real Estate Investment Trusts returns, corporate bonds, and exchange rates in endogenous variables as results of Unit Root Test, Granger Casualty Test, using 9 variables. As the results of the study, Vector Error Correction Model was estimated by using the cointegration indicating long-run equilibrium relationship. It was confirmed that the cointegrated relation existed between the Real Estate Investment Trusts market and the financial asset variables through the Vector Error Correction Model analysis.

부동산투자신탁(REITs)의 상관성에 관한 연구

장용삼(Jang Yong Sam),김진호(Kim Jin Ho),김행종(Kim Haeng Jong) 한국지적학회 2008 한국지적학회지 Vol.24 No.1

  지금까지 부동산투자신탁(REITs)에 관한 연구는 부동산 수익률과 타 자산 수익률 사이의 관계에 초점을 두고 연구되어 왔으나, 최근에는 부동산수익률과 자본시장의 자산수익률과의 관계 등 보다 미시적 측면으로 접근하는 경향이 있다. 이에 본 연구에서는 우리나라의 부동산투자신탁과 타 자본시장의 자산수익률과의 상관성을 실증적으로 검증하고자 REITs와 주식 및 채권의 수익-위험 분석을 통해 REITs의 특성을 분석하였다. 상승장과 하락장의 두가지 형태로 분석한 결과 REITs는 시장상승기보다 시장하락기에 KOSPI지수와 더 밀접하게 연동하는 경향이 높은 것으로 나타났다. 게다가 2가지 패턴인 (1)시장 상황에 따른 REITs와 소형가치주와의 관계, (2)REITs와 소형주와의 관계로 나누어 분석한 결과, REITs 베타에서는 소형주효과를 확인할 수 있었으며, 우리나라 REITs시장에서는 비대칭성이 존재하는 것으로 나타났다.   The relationship between real estate returns and the returns of other asset classes has been the focus of many academic studies. Recent studies have documented a curious aspect in the relationship between real estate returns and capitalization equity returns. We examine the correlation between the return of Korean Real Estate Trusts(REITs) and the other assets. We analyze the characteristics of REITs in term of risk and return by comparing with the other stocks and bonds.<BR>  We find that the returns on equity REITs have different risk and return properties in advancing and declining markets. The finding relies on analysis showing that REITs returns more closely track the returns of the KOSPI Index when the general stock market is declining than when it is advancing. Moreover, we test two explanations for this pattern, namely (1) the REITs and Small-value stock effects; (2) the REITs and Small stock effects. The result of our empirical study shows that the small stock effects in betas are found to satisfactorily describe the beta pattern in REITs. We also find that the existence of asymmetry in REITs markets.

지역별 오피스시장의 구조차이와 요인분석

장용삼(Jang, Yong-Sam) 한국지역개발학회 2006 韓國地域開發學會誌 Vol.18 No.2

This paper examine whether there is any regional disparity of office markets of 8 city areas in Japan, or not. At first we show lagged effects between rents and vacancy rate of the offices by the Almon Lag Model, and then we induce office market structure, so as to identify structural difference between city areas. And then we classify 8 areas into two groups. The first group market is active to the demand in short term, and the other group is semi-static and semi-closed. But both groups have a three or four years delayed-market -balance system. We also examine the growth factors of the office markets by using Shift• Share analysis. We clarify the existence of regional disparity in office markets.
