Purpose: This study compared the clinical outcomes of open repair, percutaneous repair, and minimal incision repair by Achillon in ruptured Achilles tendon. Materials and Methods: The outcomes of 12 patients with open repair (group 1), 8 patients with percutaneous repair (group 2), and 10 patients with minimal incision repair by Achillon (group 3) from February 2013 to March 2016 were analyzed retrospectively. The postoperative clinical evaluations were done by the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Arner-Linholm scale, mid-calf circumference difference, one-leg heel raise difference, visual analogue scale (VAS) for postoperative scarring, time to return to work, and complications. Results: No significant difference in the AOFAS ankle-hindfoot score, Arner-Linholm scale, and time to return to work was observed among three groups (p=0.968, 0.509, and 0.585). The mean differences in the mid-calf circumference in groups 1, 2, and 3 were 1.09, 0.73, and 0.58, respectively; groups 2 and 3 were significantly higher than group 1 (p=0.002). In addition, the mean VAS scores for postoperative scarring in groups 1, 2, and 3 were 7.0, 9.1, and 9.1, respectively; groups 2 and 3 were significantly higher than group 1 (p=0.001). The mean differences in one-leg heel raising in groups 1, 2, and 3 were 2.03, 1.91, and 1.33, respectively; group 3 was significantly higher than groups 1 and 2 (p=0.010). The complications encountered were one case of deep infection in group 1 and one case of sural nerve hypoesthesia in group 2. Conclusion: Minimal incision repair by Achillon is recommended as an effective surgical treatment for Achilles tendon rupture because it minimizes the risk of complications, leads to an improved tendon strength and healing, and achieves cosmetic satisfaction.

도시재생사업에서 리츠의 활용 방안

박원석(Park, Won-Seok) SH도시연구원 2017 주택도시연구 Vol.7 No.2

This paper aims to analyze applications of REITs in urban regeneration projects. REITs can play important roles because most urban regeneration projects may include real estate development and investment. First, public funds useful for urban regeneration projects were identified through case studies of Assembly Row of Federal Realty in US and Roppongi Hills Mori Tower of Mori Hills REITs in Japan. Second, three models were suggested for applications of REITs in urban regeneration projects, including independent participation model, PFV-REITs model, and exit strategy-division of roles model.

한국 금융시장의 지역적 차별성

박원석(Won Seok Park) 한국지역학회 1997 지역연구 Vol.13 No.1

The purposes of this study are, first, to examine the presence of the regional differences of the financial market in Korea especially focusing on those between Seoul and the other regions, and second, to elucidate the existence and characteristics of regional financial markets segmented from the national financial market by way of analyzing factors and channels to generate them. Seoul and the Taegu Area, which includes the City of Taegu and its surrounding Kyongbuk Province, have been selected as sample areas representing financial core and periphery, respectively. In order to accomplish these purposes, a review of the related literature has been made, and a theoretical framework for the study has been built. Some operational definitions have been made : ①the concept of "regional differences of financial markets has been adopted as being broadly applied to the cases that regional differences occur in the indicators which represent financial market equilibrium, ②the concept of ``regional financial market,, has been defined as being applied to the cases that the mechanism of determining financial market equilibrium exists endogenously in the subnational boundary. As the criteria to test the existence and characteristics of regional financial market, alternative models of regional financial market have been reviewed. These are classified into ①perfect integration type, ②interest spread type, ③credit rationing type, ④interest spread-credit rationing-jointed type. From these, ①interest spread, ②credit rationing, ③degree of funds concentration have been adopted as the criteria to, elucidate the presence of the regional differences of financial market in Korea, and again the first two have been adopted as the criteria to elucidate the existence and characteristics of regional financial market. Quantitative methods such as statistical data analysis and t-test, as well as qualitative methods such as interview data analysis have been used. The data for this study were obtained from diverse sources including secondary statistical data, internal aggregated data from financial institutions and first-hand data from questionnaire and interview surveys to financial institutions and firms. The results of the study are summarized as follows. First, regarding the presence of the regional differences of the financial market in Korea, first of all, an investigation of `loaned money ratio by region` data and so on, shows that Seoul lies in the financial core, and the other regions lie in the financial peripheries in Korm. For more details, examining the presence of the regional differences using the criterion of `interest spread`, we do not find any coherent differences between regions. By the criterion of `degree or funds concentration`, however, we find the patterns that more funds are concentrated in Seoul relative to its producing capacity, and by the criterion of `credit rationing`, that debtors of the other regions are experencing more credit rationing than those of Seoul. Accordingly, we can identify that the regional differences of financial market occur between Seoul as a financial core and the other regions as financial peripheries. Second, regarding the presence of the regional differences of the, financial market between Seoul as a financial core and the Taegu Area as a financial periphery, first of all, an examination of the spatial boundaries of financing by firms and financial institutions assures that Seoul and the Taegu Area are appropriate regional divisions as case regions in which financial transactions are made. Thus, by the criterion of `interest spread`, coherent differences between firms of each region do not exist. By the criterion of `credit rationing`, however, we find that small and medium-sized firms of the Taegu Area are suffering more credit rationing than those of Seoul. Moreover, by analyzing indicators about channels of credit rationing, we find three regional factors, ①difference in the limitation

박원석 ( Won-seok Park ),허승욱 ( Seung-uk Heo ),김장오 ( Jang-oh Kim ),민병인 ( Byung-in Min ) 한국방사선학회 2018 한국방사선학회 논문지 Vol.12 No.2

본 연구는 표준 감마선 조사장치의 유효빔 크기를 실측과 시뮬레이션의 결과를 비교하여 유효빔 영역의 결정에 유용한 수단을 제공하고자 하였다 시뮬레이션과 전리함을 이용한 실측의 결과는 공기커마율의 경우는 상대오차 4.5~7.3% 범위에 분포하였다. 유효빔 영역의 크기는 시뮬레이션의 경우 수평 방향 27cm, 수직 방향 21.6cm로 구현되었고, 필름을 이용한 실측결과는 수평 방향 26.5cm, 수직 방향 21.9cm로 유사한 결과가 도출되었다. 수평방향의 상대오차는 1.85%, 수직 방향은 1.38% 이며 유효빔 영역도 감마선장을 중심으로 유사하게 분포하였다. 감마선 조사장치에 있어서 시뮬레이션의 유효성이 충분함을 확인하였다. 특히 공기커마율보다 유효빔 크기의 상대오차가 적은 것은 빔의 크기가 표준선원의 용량보다는 기하학적 요인으로 결정되기 때문인 것으로 판단된다. 향후 시뮬레이션을 이용한 광자 에너지 분포도의 신뢰성을 높이기 위한 연구가 필요 할 것이다. In this study, we compared the measured values of the effective beam size of standard gamma irradiator with the simulation results to provide a useful means to the effective beam area determination. Results of the simulation and measured using ion chamber was distributed in a relative error of 4.5 ~ 7.3% of the case of air kerma rate. The size of the effective beam area is when the simulation was implemented in the horizontal direction 27cm, 21.6cm vertical direction, the measured result using a film was obtained similar results with the horizontal direction 26.5cm, 21.9cm vertical direction. The relative error in the horizontal direction is 1.85% and 1.38% vertical effective beam area was also similarly distributed around the field gamma rays. As a result of the study, it was confirmed that the effectiveness of the simulation was sufficient for the gamma irradiation system. In particular, it is small relative errors in the effective beam size than the air kerma rate is considered to be due to the size of the beam is determined by geometric factors rather than the capacity of the standard source. A further study is needed to improve the reliability of the photon energy distribution diagram using simulation.

박원석(Park, Won Seok) 한국부동산연구원 2020 부동산연구 Vol.30 No.3

본 연구의 목적은 프랑스, 네덜란드, 독일 등 주요 EU 회원국을 사례로, 부담가능주택의 공급 및 자금조달 체계를 비교·분석하고, 국내 활용 방안을 도출하는 것이다. 연구결과를 요약하면 다음과 같다. 주택체계론의 관점에서 프랑스, 네덜란드, 독일은 모두 단일적 임대체계와 선별적 일반모형/대중모형을 채택하고 있어, 부담가능주택의 확충에 주거정책의 초점을 두고 있다. 부담가능주택의 공급주체는 공공과 민간 모두이며, 입주대상은 대체적으로 중간소득층 이하이며, 소득수준에 따른 임대료의 차등화가 이루어지고 있다. 부담가능주택의 확충을 위해 이들 국가는 다양한 재정지원 체계를 가지고 있으며, 부담가능주택의 지속가능한 운영을 위한 다양한 민간자금 조달수단을 가지고 있다. 국내에서도 주거복지 사각지대를 줄이기 위해 부담가능주택의 확충이 필요한데, 부담가능주택의 체계적인 공급을 위해서는 기관투자자에 의한 공급 방안을 마련하는 것이 필요하다. 이러한 방안으로 본 연구에서는 비영리 기업형 모형과 영리 기업형 모형을 제안하였다. The purpose of this study is to analyze the characteristics of the supply and financing system of affordable housing, and to derive policy implications for domestic use measures. The study results are summarized as follows. Based on the perspective of the housing system theory, France, the Netherlands, and Germany all adopt a unitary rental system and selective general model/mass model, so the focus of the housing policy is on the expansion of affordable housing. The supplier of affordable housing is both public and private, and the target class of affordable housing is mainly below the middle income class. Furthermore, the rent is differentiated according to the income level. For the expansion of affordable housing, these countries have various financial support systems and private financing means for the sustainable operation of affordable housing. In Korea, it is necessary to expand affordable housing in order to reduce the blind spot for residential welfare. It is also necessary for institutional investors to prepare a supply plan for the systematic supply of affordable housing. In this way, the study proposed a non-profit enterprise model and a for-profit enterprise model.

Third, public-private partnership-type financing models that can be used in Korea include a REITs-type model, a private investment project-type model, and a cross-subsidiary model.

지역개발사업을 위한 개발금융 활성화 방안

박원석(Won Seok Park) 한국경제지리학회 1999 한국경제지리학회지 Vol.2 No.1

본 연구에서는 우리 나라 현 개발금융의 현황과 문제점을 살펴보고, 지역개발사업의 확대를 위한 개발금융 활성화 방안을 모색하였다. 지방자치제 이후 지역경제를 활성화하기 지역개발사업에 대한 관심이 증가하고 있는데, 이러한 지역개발사업의 확대를 위해서는 개발금융의 활성화가 필요하다. 그런데 현 개발금융의 실태를 보면, 개발기능이 영세하고 미분화되어 있으며, 제조업 위주의 금융자원 배분으로 제도권 금융시장에의 접근성이 낮으며, 기업금융 방식이 지배적이어서 사업금융이 발달하지 못하였으며, 자본시장의 활용이 미비한 등의 문제점이 나타난다. 이러한 맥락에서 개발금융의 활성화하기 방안으로, 첫째로 부동산 지분투자펀드의 활용 방안, 둘째로 프로젝트 파이낸싱의 활용 방안, 자신담보부증권의 활용 방안, 넷째로 메자닌 캐피탈의 활용방안을 도출하였다. The aims of this study are to analyze the current states and problems of development finance in the regional development projects, and to examine new sources and techniques of development finance for activating regional development projects. Analyzing the current states of development finance in regional development projects, the problems such as the poorness of development function, the low accessibility to formal financial market, especially capital market, and the dominant use of corporate financing can be seen, In these context, four alternatives are proposed in order to activate development finance. First alternative is to use the funds which invest the equity of real estate, such as REITs. The second is to activate project financing. The third is to use asset backed securities. The forth is using mezzanine capital as the means of protecting investors.
