도시철도 개통에 따른 역세권 지가의 특성에 관한 연구 : 광주시 도시철도 1호선을 중심으로

김유호 전남대학교 대학원 2009 국내석사

도시철도역은 현대도시에서 지역내 및 지역간을 연결하는 통행의 관문이며, 도시개발을 유도하는 교통의 결절지역이 되고 있다. 이러한 도시철도역 주변에는 많은 사람들이 밀집하여 여러 가지 경제·사회적 활동을 하면서 다양한 상권들이 형성되어 하나의 역세권을 형성한다. 근년에 한국에서 역세권 개발에 대한 관심이 점점 높아지면서 도시철도역을 하나의 복합기능 역세권으로 개발하는 사례가 많아지고 있다. 이러한 대규모 개발사업을 통하여 도시철도 주변의 상업지역은 단기간에 토지개발 및 경제활동 측면에서 갑작스러운 변화를 겪고 있다. 그럼에도 불구하고 도시철도역의 개발이 그 주변지역에 어떠한 변화와 영향을 미치는 가에 대한 상세한 분석과 실증적인 연구는 부족한 실정이다. 본 연구는 광주도시철도 1호선 주요 역세권인 남광주역, 문화전당역, 및 상무역을 중심으로 도시철도 개통 전·후의 역세권 지가변화를 분석하고 있다. 연구의 주요내용은 크게 도시철도 역세권 지가의 이론적 고찰, 광주도시철도 운영실태와 역세권 지역의 특성 및 도시철도 역세권 지가의 특성분석 등으로 구성되어 있다. 본 연구의 주제와 관련된 선행연구들을 문헌적 고찰을 통해 살펴보았다. 사례분석의 대상지는 연구의 성격과 대표성을 감안하여 남광주역 역세권, 문화전당역 역세권, 상무역 역세권 중심으로 선정하였다. 역세권의 지가의 특성분석은 광주도시철도 개통시점인 2004년을 기준으로 개통 3년전 (2001~2003년)과 개통 3년후 (2005~2007년)를 대상으로 연도별로 공시지가를 조사하여 활용하였다. 사례지역 역세권별로 분산분석을 실시하여 용도지역, 도로 및 부지형상 등이 지가에 미치는 영향을 분석하고, 거리와의 상관분석방법으로 지가특성을 분석하였다. 사례지역 대상 3개의 역세권별 거리에서 약간의 지가의 차이는 있으나 도시철도 개통 전·후의 지가의 변화는 미미한 것으로 드러났다. 지가를 종속변수로 하고 용도지역, 도로, 부지형상을 독립변수로 하여 도시철도개통 전·후의 지가 변화율을 도출하였다. 분석결과 도시철도 역세권 내부지역과 외부지역을 나타내는 가변수의 결정계수가 유의한 값을 보여주었다. 분석결과를 보면, 연구의 대상지역인 도시철도 1호선의 상무역세권을 제외한 남광주 역세권 및 문화전당 역세권은 미미한 지가 차이를 나타내었다. 향후 광주시 도시철도 2·3호선이 계획대로 완공된다면, 대중교통체계의 연계성이 구축되고 대량의 교통수요가 발생할 광주역 및 광천동 버스터미널 역세권은 많은 유동인구를 증가시킬 것이다. 이러한 유동인구의 증가는 도시철도 접근성의 향상과 토지이용 잠재력 증가를 초래하여 역세권 지가상승의 요인으로 작용할 것이다. 현실적으로 연구의 성격상, 광주시 도시철도 1호선의 개통 전·후의 역세권 지가변화의 영향은 제한적으로 발생하였다. 이를 감안하여 장차 광주시 도시철도사업의 시행할 경우에 도시철도 역세권을 도시개발과 성장거점으로 육성하기 위한 지구교통 및 지구단위사업계획에 따른 종합적인 역세권개발계획의 수립이 중요하다. 본 연구는 도시철도 개통 전·후 단기적인 지가분석, 역세권 사례지역의 제한, 및 지가특성 분석변수의 도입에서 연구의 한계점이 드러나 있다. 향후 연구에서는 도시철도역의 실제특성을 반영하는 역세권 범위의 확대, 분석변수의 추가적용(즉 건축물의 주용도, 지하철의 이용객수, 대중교통노선 수, 도보접근성 등) 및 실거래 지가중심의 자료분석 등의 연구·분석이 더욱 요망된다. This study shows that access to urban railway station affects the development of railway station's surrounding zone (RSSZ). For instance, the value of the property in RSSZ is likely to rise on the basis of the before and after the opening of a urban railway. Urban railway system is believed as an important solution to resolve worsening transport problems in metropolitan city. Also, the opening of a urban railway line is expected to affect the change of urban spatial structure, and to have more influence on land price of RSSZ. Nam Gwangju station, Moonhwagendang station, and Sangmu station were selected as the case study areas in order to analyze the land price changes in RSSZ. RSSZ is limited to the area of a 10 to 500m radius of a urban railway station in this study. The changes in land price by RSSZ were analyzed using analysis of variance and Correlation Analysis in terms of land use, road form, site shape and distance. Time-series analysis of sifts in land prices of RSSZ is conducted during the 2001-2007 period. It was found that there was little change in land price of RSSZ before and after the opening of urban railway line 1 in Gwangju City in general. Land in the surrounding zone of Sangmu station rose in value after the opening of Gwangju urban railway line 1. The price of land in RSSZ seemed to have something to do with perceived proximity to urban railway station. Land price at the year of 2004 when Gwangju urban railway line 1 opened was a little higher, compared with that at the time of urban railway plan. This implies that there are a lot of zones in Gwangju that the public announcement of urban railway construction may bring about the changes in land price of RSSZ. For instance, land value in the area of a 100m radius from urban railway station increased significantly just after one year when urban railway began to construct. It is suggested that significant policy directions for Gwangju's RSSZ are associated with establishment of the scope and development strategy, preparation for the implementation strategy about it, and selection of land use & development functions along with the urban railway master plan.

〈Abstract〉 A study on the crime-prevention based on the user-centered design using the location information of ankle monitor Kim, Yu-Ho Electronic Monitoring(Ankle Monitor) System was introduced as the drastic measure in respond to the specific circumstances of sexual violence crimes on September 1, 2008 in South Korea. It had been enforced on kidnappers, murderers and finally expanded to burglars in June, 2014. It had showed a great effectiveness on the suppression of recidivism against the offenders in ankle monitor for the first 3 years. However, the recidivism rates of offenders in ankle monitor have been increased sharply every year compared to last year's since then. Hence, our government tried to settle the matter with various and constant efforts, but there was no effect and it caused people to think of the system as a useless one. Here is the question that actually the current electronic monitoring system just indicates the whereabouts and movement route of offenders in ankle monitor, so it can't show what the offenders are doing. It is really serious problem and dangerous to ordinary people. This study would like to suggest a new approach, the crime-prevention based on the user-centered design using the location information of ankle monitor, to cope with the matter and it enables citizen(user) to avert the danger and protect them for themselves in advance from offenders in ankle monitor. In addition, it will lessen the workforce of probation officers. Therefore, this thesis aims to give the authorities a chance and motive to take the subject of this study as their one of studies, when the government has to try to lessen the recidivism rates of offenders in ankle monitor and reform the electronic monitoring system.  Key Words : Electronic Monitoring System, Ankle Monitor, Location Information of Ankle Monitor, Recidivism Rates, User-Centered Design, Crime-Prevention 국문 초록 전자감독(일명 전자발찌)제도는 특정 성폭력범죄 환경에 대응하고자 2008년 9월 1일 특단의 대책으로 도입되었다. 시행 초기 3년간은 매년 1% 미만의 재범률을 보일만큼 전자발찌착용자의 범죄 억제에 큰 기여를 하였으나 2011년 이후로는 전년 대비 매년 큰 폭으로 재범률이 상승하여 제도의 실효성에 문제가 제기되었다. 그에 대한 원인으로는 대상 범죄의 확장에 따른 전자발찌착용자수의 급증에도 불구하고 지도·감독 인력이 효율적으로 충원되지 못한 이유와 전자발찌 착용 상태에서의 범죄나 훼손 후 범죄의 경우처럼 처벌을 각오하면서 범죄로 나아간 경우에는 국가가 선제적으로 이에 대응하지 못한 결과 범죄예방 기능이 약화되어 제도의 실효성을 저하시키는 한계의 요인으로 작용했다. 이에 대해 정부가 지속적인 개선의 노력을 하였으나 재범률 상승이라는 부정적 현상은 해결되지 못하고 국민의 안전에 위해요소로 상존하면서 최근에는 제도의 무용론까지 거론되기에 이르렀다. 우리 사회가 흉포한 범죄의 예방을 목적으로 도입한 고비용의 제도가 제 역할과 기능을 다하지 못한다면 국가 경제적으로 손해인 것은 당연하고 그 보다 더 위험한 것은 그로 인해 필연적으로 뒤따르는 무고한 시민의 희생이다. 모두가 주지하듯이 범죄는 예방이 최선이다. 그 이유는 한번 발생한 범죄의 피해는 결코 다시 되돌릴 수 없기 때문이다. 그러므로 특정 범죄자가 범행을 결의하고 대상을 물색하는 단계에서 잠재적 범죄피해자인 시민이 스스로 위험을 회피할 수 있는 능동적이고 선제적인 범죄예방 모델의 개발이 반드시 필요하고 그에 대한 효율적인 방안으로 이 논문에서 주장하는 전자발찌 위치정보를 활용한 사용자중심의 범죄예방 모델에 관한 연구는 헌법적 가치 충돌의 문제와 실정법적 한계를 지닌 현 상황에서도 개념적으로 충분한 의미를 가진다고 본다. 따라서 본 연구에서는 관념의 틀을 벗어나 범죄예방을 위한 패러다임의 전환을 시도하고자 한다. 즉 지금까지 범죄자정보를 독점하고 있는 국가가 잠재적 범죄피해자인 시민(사용자)과 특정 범죄자에 대한 위치정보를 공유하는 방식으로 사용자중심의 범죄예방 수단을 보충적으로 제공함으로써 특정 범죄자의 재범위험으로부터 시민의 불안감 해소는 물론 부족한 보호관찰관의 업무량 경감과 효율적 업무수행에도 도움이 될 것으로 기대하며 나아가 전자발찌 본연의 기능과 더불어 범죄자가 재범을 결의하는데 심리적 가중 장해요소로 작용하여 특정 범죄자의 재범 억제에 시너지 효과를 보일 수 있을 것으로 기대한다. 그리하여 정부 소관 부처가 향후 이 제도의 개선을 위한 다양한 연구를 시도해야만할 때 그 중 하나의 연구과제로 채택할 기회와 동기를 부여하기 위해 이 논문을 작성한다.  주요어 : 전자감독제도, 전자발찌제도, 전자발찌 위치정보, 사용자중심설계, 전자발찌 재범률, 범죄예방  학 번 : 2014-24855

한국의 지역응급의료 조직간 대응체계 분석 : 재난관리공동체와 파트너십 이론을 중심으로

김유호 충북대학교 2010 국내박사

This study started from the problem that Korean emergency medical service systems, which are for people?fs health and medical service, are integrated compared to those in developed countries and there are few local emergency medical service systems based on cooperation among public sectors, private sectors, and NGOs. That is, it was initiated with recognition of the importance of emergency medical services in preparation for disasters. Besides, cooperation between public and private sectors was considered crucial in the current situation when private sectors were increasingly important as resources related to emergency medical service were more abundant in private sectors than in public ones. Based on these discussions, this study reviewed previous studies on emergency medical service systems. In addition, using the results of previous research on partnership and communities and applying variables necessary to form disaster resistant communities(DRC) proposed by Geis, et. al. (2000), we suggested a research framework. Focused on factors for the formation of disaster management communities to establish the partnership of local emergency medical service, we performed case study, empirical analysis and AHP analysis. Through these processes, this study attempted to identify factors for the formation of communities and to find current problems in community formation and suggest solutions for the problems. According to the results of the case study, first, in both the Daegu Subway Fire in 2003 and the Icheon Refrigerated Warehouse Fire in 2008, the biggest problem was that various involved institutions failed to overcome selfish departmentalism. Second, various involved institutions participated in resource organization, but efforts were not sufficient to make detailed consultation and coordination and to take actions for promoting participation and cooperation of public and private medical institutions for relief activities. Third, with regard to situation analysis?]judgment, most of systems and research publications focused on the general situation of disasters without detailed situation analysis and judgment of emergency medical service. This suggests the necessity for clear definition of each institution?fs roles. Fourth, there was no sharing of common goals in terms of planning against disasters. Fourth, in the integration, besides education of rescuers, there was no preliminary education for promoting close cooperation among involved institutions on the occurrence of a disaster. Lastly, many private volunteers participated, but their activities were limited to services such as food rationing. Thus, it was keenly required to invite private medical institutions to participate actively. On the other hand, multiple regression analysis was performed in order to examine the relation between factors related to the formation of local emergency medical services and disaster management communities and the effectiveness of local emergency medical services. According to the results, the effectiveness of local emergency medical services was influenced most positively by the participation factor(b: 0.250, ??: 0.248), which was followed by the planning factor(b: 0.224, ??: 0.218), the integration factor(b: 0.201, ??: 0.207), and the cooperation base factor (b: 0.167, ??: 0.149). However, the resource factor and the situation factor did not have a significant effect. This result shows that what is most important for strengthening the partnership of local emergency medical services is the participation of a large number of institutions and, moreover, it is necessary to make plans for cooperation among the participant institutions and to integrate for role allocation. What is more, in the results of analyzing the priority of measuring areas related the formation of disaster management communities for local emergency medical services, the cooperation base factor(0.406) was considered most important(0.406), which was followed by the integration factor(0.178) and the participation factor(0.165). This means that specialists?f opinions were different from the result of regression analysis with field workers in Section 1, in which positive influence was strong in order of the participation factor(b: 0.250, ??: 0.248), the planning factor(b: 0.224, ??: 0.218), and the integration factor(b: 0.201, ??: 0.207). The reason for this difference is that while specialists considered it most important to lay the base for the formation of local emergency medical service communities by establishing trust among participant institutions and inducing their voluntary participation, field workers considered that the first requirement for the formation of such communities is the participation of as many and various institutions as possible. For the effective formation of disaster management communities for local emergency medical services in the future, it is most necessary to build trust among institutions. In addition, public and private sectors should exchange substantial personnel and material resources, and make analysis and judgment on disaster and medical situations jointly. Another keen requirement is regular integrated training. Furthermore, it is necessary to organize a consultation body for coordination among institution and to induce the participation of specialists from private sectors.

This study develops and validates a counseling rapport scale to reflect the concept of relations between a counselor and his or her client. Based on related theories and previous studies, this study tested a research model to examine the mediating effects of working alliance on connections between counseling rapport and counseling session evaluation. Research 1 developed and validated a scale for adult clients, around the nation, who finished the first counseling session and were preparing for the second one. First, preliminary items were selected based on previous studies and an open-ended questionnaire for the counseling rapport scale for clients. An item analysis was conducted to select 50 preliminary items, which were put on the survey, and an exploratory factor analysis was conducted with 250 clients who had finished their first sessions. The analysis results led to a scale of four factors and 21 items. The four factors included Expectation dimension (six items), Preparation dimension (six), Comfort dimension (six), and Genuineness dimension (three). Secondly, another 250 clients, who finished their first sessions, were sampled to carry out a survey and confirmatory factor analysis. Finally, criterion-related and convergent validity results and test-retest reliability results were all favorable, which indicates that the scale developed was a valid and reliable one to measure counseling rapport. Research 2 tested whether workinging alliance could mediate relations between counseling rapport and counseling session evaluation with a structural equation model by analyzing the data of 250 clients. The findings were as follows: first, a structural model among counseling rapport, working alliance, and counseling session evaluation was appropriate for data; second, counseling rapport had positive effects on working alliance; third, counseling rapport had sequential effects on counseling session evaluation via working alliance. These findings demonstrate that counseling rapport had both direct impacts on counseling session evaluation and indirect ones on it via working alliance. The present study checked the constructs of counseling rapport for early clients and developed as well as validated a counseling rapport scale through them. The counseling rapport scale for clients will facilitate research on the formation of rapport between counselors and their clients and thus provide useful basic data for counseling. Secondly, the present study examined the effects of variables related to the psychodynamic theory and previous studies on counseling session evaluation, thus promoting the utilization of positive and negative aspects in counseling rapport, working alliance experienced by clients in relation to counseling evaluation for counseling and educational purposes.

This study attempted to examine the priority factors among the components to improve the infection control system of the hospital organization by analyzing the relative importance of variables such as hospital regulations, hospital cooperation, hospital organization, and hospital workforce factors through the analysis of literature and previous studies in order for the hospital organization to derive the components for the improvement of the infection control system where the hospitals respond quickly to the crisis when new infectious disease is developed. For this, the AHP technique was applied to four groups of infectious diseases experts such as central government (Ministry of Health and Welfare, Disease Control Headquarters), local governments (local governments, public health centers), hospitals (national and public hospitals), and the academia (academic professors). Eventually, in the results of analyzing the relative importance of the components in the measurement areas for the improvement of the infection control system of the hospital organization with regard to infectious disease experts (total), hospital personnel factors (34%) were recognized as the top priority such as securing and supporting professional manpower, supervisor’s leadership, and amicable communication between members, etc. The hospital's regulatory (institutional) factors (28%) were recognized as the second priority such as restructuring of infectious disease management regulations, specification of manuals, and appropriateness of rules and manuals, etc. The organizational factors (23%) of hospitals were recognized as the third priority such as dedicated organization operation, education and training, resources (budget) acquisition and support, etc., and the cooperation factors (15%) of the related institutions of the hospital were recognized as the fourth priority such as building cooperation and support systems, creating trust among organizations, and exchanging information among organizations. As above, infectious disease experts (total) were found to recognize that it is necessary to improve the staffing factors of hospitals such as securing and supporting specialists related to infectious diseases, leadership of supervisors, and communication among members. Also, in the relative importance analysis, which takes into consideration the composite weights of the measurement factors, it was found that they recognized that it is important to secure and support the experts related to the infectious diseases. In other words, it was found that securing of infectious disease management specialist, nurse, infection management experience and knowledgeable manpower based on laws and guidelines, and the support of expert staff at a nation’s perspective should be given top priority Specifically to look at the differences among groups, first, central government’s infectious disease management specialists perceived hospital workforce factors (40%) as the first priority, and they perceived that the hospital's regulatory (institutional) factors (24%) and the hospital's organizational factors (24%) were both important as the second priority. In other words, the central government's infectious disease management specialists recognized that the personnel factors of hospitals should be improved to the first place in order to improve the infectious disease management system of the hospital organization, such as securing and supporting professional manpower, leadership of supervisors, and amicable communication between members, etc. Second, the local government’s infectious disease management specialists recognized hospital personnel factors (37%) as the first priority, such as securing and supporting professional manpower, leadership of supervisors, and amicable communication among members, etc. it was found that they recognized that hospital regulatory (institutional) factors (24%) were important as the second priority, including restructuring of infectious disease management regulations, specification of manuals, and compliance with regulations and manuals, etc., and that organizational factors (22%) such as dedicated organization management, education and training, resources (budget) acquisition and support were important as the third priority, etc. Third, the hospital infectious disease management specialists were found to recognize that both the hospital personnel factors (31%) such as securing and supporting professional manpower, leadership of supervisor, and amicable communication among members, and the hospital regulatory (institutional) factors (31%) such as restructuring of infectious disease management regulations, specification of manuals, and compliance with regulations and manuals, etc. were important to the first place, and they were found to recognize that hospital organizational factors such as dedicated organization management, education and training implementation, resources (budget) acquisition and support were important to the third place. Fourth, it was found that academic professors in academia recognized hospital regulatory (institutional) factors (31%) as the first priority, including restructuring of infectious disease management regulations, specification of manuals, and appropriateness of regulation and manual implementation, etc., the hospital personnel factors (29%) as the second priority, including securing and supporting professional manpower, leadership of supervisors, and amicable communication among members, etc., the hospital organizational factors (23%), as the third priority, including operating a dedicated organization, conducting education and training, securing and supporting resources (budget), etc., and the cooperative factors (17%) of related organizations in hospitals as the fourth priority, including building cooperation and support systems, creating trust among organizations, and exchanging information among organizations, etc. In fact, these results show that they recognize the importance of the human resources of hospitals different from the above specialists of central government, local government, and hospitals who recognized the human resources of hospitals as the top priority. In addition, in the analysis of relative importance by classifying infectious disease management specialists (total) by group and considering composite weights by measurement factors, it was found that the central government recognized the importance of chief leadership, that is, top decision makers’ leadership improvement that could lead the medical staff and all employees of all departments in the hospital to monitor, control, and regulate hospital infection as the first priority. It was found that the central government, hospitals and academia common recognized the importance of securing and supporting professional manpower, that is, securing the infection control specialists and nurses, the staff with infection control experience and knowledge, and for this, the improvement of national expert staff support based on laws and guidelines as the first priority. The four measurement domains and 12 detailed measurement factors used in this study are variables presented through the existing literature analysis and previous studies. However, according to the follow‐up study, the four measurement domain variables may be integrated or increased. In addition, 12 variables suggested as the detailed measurement factors may be presented as a new variable that has not been previously presented due to changes in the internal and/or external environment of the infection management in subsequent studies. Also, as some of them may be integrated or eliminated, we will carry out further research according to the changes of environment of infectious disease.

The study analyzed North Korean reform and open-door policies and Chinese roles. Social and economic systems of the Communist Parties of the former Soviet Union and Eastern Europe countries collapsed at once but China which is Communist nation, through system switchpolicy, can complete peculiar system, called socialist market economy, with the Communists' domination in politics and fulfilling capitalism in economics. China could emerge as Gs which is the world strongest country and could surpass America with unprecedented spatio-temporal compression increase after 30 years of reform and open-door policy using socialist market economy. Without excluding or dissolving plans and working together with market, Chinese system reform succeeded in fulfilling moderatism and promoted development of secondary industries through success of initial country planning and reassignment of surplus labor based on political stability and gradual reform and open-door policy through successful use of exclusive industrial zone. In politics, economics, and foreign aspect, North Korean reform and open-door conditions are found to be more difficult than Chinese. North Korean crucial disadvantageous conditions than Chinese initial conditions is the existence of ethnic issues and unification problems so they worry about absorption unification led by Korea and America and maintain personnel and ideological continuity of leadership with passing down power through 3 generation. Hence, North Korean also recognizes such concerns but due to seriousness that system crisis can bring the collapse of regime and because they cannot stick only to self-rehabilitation and North Korean style socialism, they accept Chinese models but will pursue equidistance policy between northern region diplomacy and southern region diplomacy by pursuing restoration of relations with Russia and improvement of relations with Korea, America, and Japan worrying about Chinese influence and subordination. Therefore, participant countries of six-party talks including China and international organizations should send cooperation and support to North Korean so that it becomes normal country with solving nuclear problem and economic growth by establishing advantageous conditions to pursuing reform and open-door policy.
