This paper examines the validity of issuing municipal bonds for land compensation of long-term unexecuted urban parks and greenbelts. Then it suggests that municipal bonds should be issued for compensation priority areas with high rising prices. By conducting correlation analysis and PLS(Partial Least Squares) regression for 32 long-term unexecuted urban parks and greenbelts, the factors were identified that affected 'rising prices of IAPLP(Individually Announced Public Land Price) after seven years'. According to the analysis results, Variable Importance in the Projection in PLS regression was higher in 'IAPLP of base year(1.919)' and 'Accumulated rising Rates of average IAPLP in the borough(1.176).' The implications of this study are as follows. In Seoul, the accumulated rising rates of average IAPLP over the past 12 years is higher than the accumulated interest rates for seven years of urban planning facility bonds, which means that IAPLP have risen more than the interest payments due to the issuance of municipal bonds. In addition, since the actual compensation is three times that of IAPLP, it is judged that the land price is actually much higher than the interest payments. This shows that issuing municipal bonds and preferentially compensating for areas like high rising land prices can increase the economic efficiency of the budget execution. Also, for economic efficiency of budget execution, it is necessary to propose an 'area with high IAPLP' or 'a part in the borough with high rising rate of average IAPLP,' which is expected to have a high rising land price as criteria for compensation priority areas. In the future, when issuing municipal bonds to compensate long-term unexecuted urban parks and greenbelts, variousresearch on financing for municipal bonds repayment should be conducted.

The purpose of this study is to propose a plan that properly organizes urban close-to-nature streams by evaluating the city park functions, ecological functions and landscape functions required for urban stream and setting up space function suitable for the space. The site of this study is Hongjecheon located in Seodaemun gu of Seoul City, whose length of channel spans 6.12km in total. The plan for the construction of close-to-nature streams had been established from late 2003, and the construction was completed. Evaluation Categories and indications were deduced from 4 stages. First, based on theoretical examination, we made a list of stream and park evaluation categories and added Category about Characteristic of urban streams. Next, we set Final Evaluation Categories and indications through the process of goal-relevance, indication verification, merging similar category. Final Evaluation Categories were deduced such as usage demand, usability(city park functions), biodiversity, inhabitation potential, rarity(ecological functions), historical cultural elements, and landscape Quality(landscape functions). As a result of allotting space functions, zones 1 through 4, got high grades at usage demand, was classified as a civic resort district; zones 5 through 6, close to major green area and remained original landscape, as ecological conservation and restoration district; zones 7 through 8, get high grades at usage demand and usability, as environmentally-friendly use district; and zones 9 through 10, many historical cultural elements and view points, and high green possession rate, as stream scenic district. In addition, detail space function and construction plan for each zones were proposed. As a result of this study, proposed space function assignment considering natural characteristics, humanities and social characteristics and landscape characteristics and is expected to be utilized at reasonable spatial planning considering various functions required for urban stream.

This study was conducted to help staff members of health centers manage personnel by examining the staff members' recognition level of organization structure of health centers, their motivation, their job satisfaction level and its related factors. Data were collected from 471 staff members of 14 health centers from March 3, 1999 to April 30, 1999. The results of this study are summarized as follows. In recognition levels of organization structure of health centers, the recognition level of necessity of discretion right was highest(3.55 points on the base of 5 points), while the recognition level of the location of decision making right was lowest(2.77 points). The general recognition of organization structure of health centers was 3.06 points, the suitability of division of duties was 3.05 points, and the optimum of manpower and budget was 2.93 points. The staff members' general recognition level of the organization structure appeared significantly higher in case of the groups of small and medium sized cities, above fifties, below high school graduate, above the sixth grade, public service experience of above 20 years, service period of below 2 years at present post, and average monthly salary of one million, eight hundred and ten thousand won. In the recognition level of the location of decision making right, the groups of big cities, male, the married, above the sixth grade, health and administration posts, average monthly salary of one million, three hundred and ten thousand won to one million, and eight hundred thousand won were significantly higher than the other groups. The recognition level of necessity of discretion right was higher in case of the groups of the twenties, the unmarried, above college graduate, nursing post, public service experience of below 5 years, service period of below 2 years at present post, and average monthly salary of below eight hundred thousand won. In the recognition level of suitability of division of duties, the groups of small and medium sized cities, the married, medical technicians, public service experience of above 20 years, and service period of below 4 years at present post were significantly higher than the other groups. In the staff members' recognition levels of organization management, the recognition level of opinion response when making decision was highest(2.92 points). The recognition level of rationality of the target amount establishment method was 2.88 points and the recognition level of personnel management was 2.63 points. The recognition level of personnel management was significantly higher in case of the groups of small and medium sized cities, the forties, above the sixth grade, medical technicians, public service experience of above 20 years, service period of below 2 years at present post, and average monthly salary of above one million, eight hundred and ten thousand won. In the recognition level of opinion response when making decision, the groups of small and medium sized cities, female, the eighth grade, health and administration posts, and service period of below 2 years at present post were higher than the other groups. The recognition level of rationality of the target amount establishment method was significantly higher in case of the groups of above fifties, below high school graduate, above the sixth grade, medical service post, and public service experience of 15 to 20 years. The factors significantly influencing sanitation were sex, education level, the period of public service experience, general recognition of organization structure, recognition of necessity of discretion right, recognition of suitability of division of duties, and recognition of opinion response when making decision. The factors which significantly influenced motivation were marital status, grade, recognition of the location of decision making right, recognition of necessity of discretion right, recognition of division of duties, recognition of opinion response when making decision, and sanitation. Sex, education level, recognition of suitability of division of duties, recognition of the target amount establishment method, and motivation influenced job satisfaction significantly. The factors significantly influencing organization culture were age, the period of public service experience, service period at present post, recognition of optimum of manpower and budget, recognition of suitability of division of duties, recognition of opinion response when making decision, and recognition of rationality of the target amount establishment method. In the coming days, the staff members' job satisfaction level must be increased through motivation and efficient conduct of duty must be accomplished through rational organization structure and management. Moreover, change of the staff members' consciousness and administrative system which are suitable for local autonomy system have to be established with increase of local residents' consciousness level and education level. Forming organization culture by reformative idea which fits the new era, public health service by the Community Health Act and health education service by the Health Promotion Act must be carried out efficiently. In doing so, financial support of central government and active efforts and concerns of local governments have to be devoted in order to get public health service in which peculiarity of the community is considered to be pursued well.

This study was conducted to examine and analyze local governments, park status, project characteristics, and the implementation in detail for private park special projects across the country as a means of responding to the sunsetting of urban parks. As a result of the analysis, first, the private park special project, was found to be mainly implemented in cities with a population of more than 100,000, so there was a limit to the application on military installations or in local small cities. Therefore, rather than applying the special system collectively, it was judged that institutional flexibility, considering the characteristics and size of local government, was needed. Second, the current special projects by the park creation donation collection method shows monotonous development centered on apartment houses, so it is necessary to diversify the development by introducing a park preservation method that purchases and donates park sites. Third, it was found that the area standard needs to be eased to less than 50,000m² to include parks with high utilization and good accessibility in urban areas of large cities, as the type and area of parks are limited. Fourth, most special projects are mountain parks, which are feared to damage the natural terrain and skyline, so separate ordinances should be established and applied, and development approaches should be made to allow nature and parks to coexist with the setting of detailed building guidelines for each type of facility. The guidelines should include, first, after the nationwide private park special projects are completed, standards for appropriate returns for similar projects should be established, institutional standards such as the recovery of excess profits should be established, and environmental reviews should be conducted. Second, it was found that local governments should institutionalize the composition of private consultations to promote the efficient management of projects through a cooperative system, and third, a roadmap for maintenance after the donation of special parks should be established.

한국사회가 저출산 고령화와 고학력화의 추세, 전지구화, 지식정보화라는 세계적인 흐름을 고려할 때 앞으로도 향후 지속적인 이주인구의 유입은 불가피한 실정이다. 특히 결혼이민자들은 한국사회에서 적응하기 위한 언어와 문화적 적응을 극복하지 못한 상태에서 그들 자녀들을 교육해야 되는 열악한 환경적인 문제에 봉착하게 된다. 더구나 다문화가족 자녀는 2008년 5월을 기준으로 58,007명으로 전체 외국인 주민의 6.5%를 차지하며 다문화가족의 자녀 중 6세 이하가 57.1%로 상당히 높은 비율을 차지함을 고려해볼 때 현재 초 중등학생들을 대상으로 하는 연구는 시사점이 크다고 하겠다. 특히 전남지역의 다문화가족은 전국 최고의 비율을 차지하고 있으며 총 5,919 가족 중 영유아기와 학령기에 포함되어 있는 다문화가족 자녀 재학생수는 1,479명으로 집계되고 있다(행정안전부, 2008). 이렇게 교육대상자로서 점점 증가하고 있는 다문화가족의 학생들이 전남지역에 상당수 집중되어 있다. 이렇게 유입되는 이주자 중 결혼이민으로 인한 그 자녀의 자아존중감과 학교생활적응은 주요한 사회문제로 대두되고 있다. 그간의 연구들의 대부분은 이주여성의 생활실태와 일상에서 겪는 다양한 문제점에 초점을 맞추고 있을 뿐 그들 가정의 자녀들에 대한 연구는 미흡한 편이다. 이 연구는 2차 사회화 과정에 결정적인 영향을 미치는 학교생활에서 다문화가족 학생들의 자아존중감과 학교생활적응에 관하여 전남 동부지역 일부를 초 중등교사들을 대상으로 어떻게 인지하고 있는지를 연구하였다. 연구방법은 교사들을 대상으로 구조화된 설문지를 이용하여 인구학적 특성, 다문화가족 학생들의 자아존중감 및 학교생활적응 관련 인식들을 조사하였다. 자료분석은 SPSS Win 12.0을 사용하여 빈도분석, t-test 및 일원배치 분산분석을 실시하였다. 교사의 성별, 학교급 별, 농촌과 도시지역, 학교규모, 학년, 교육경력에 따라 유의미한 차이가 있는 것으로 나타났다.

2010년 12월 8일 국회 본회의에서 "친수구역 활용에 관한 특별법"(이하 친수법)이 통과되었다. 친수법은 국가하천의 양안 2km 이내의 지역을 엄격한 기준에 의해 친수구역으로 지정하여 체계적으로 개발하도록 제도화하였다. 또한 특히 사업시행자를 공기업 및 지방자치단체 등 공공기관으로 제한하고 개발이익도 하천정비에 재투입하여 개발이익이 사유화되거나 이윤추구의 장이 되지 않도록 하는 법적 토대를 마련하고 있다. 우리나라의 하천은 지난 수십 년간 개발일변도 정책으로 하천 본래의 모습을 찾기 어렵다. 인구의 도시집중, 지속적인 개발, 하천에 대한 기대치 증가 등으로 앞으로도 하천 자체의 자정능력에 의한 회복은 기대하기가 쉽지 않다. 4대강 살리기 사업(이하 4대강사업)은 국내 하천의 이러한 절실한 현실이 고려되었다고 한다. 그런데 4대강사업으로 조성되는 수변지역을 그대로 방치하면 무분별한 난개발과 토지투기의 장으로 전락할 가능성이 크다. 또한 수변구역 주변의 넓은 토지는 이미 농경지화되어 있어 비료, 제초제 등 비점오염원의 하천유입으로 수질을 지속적으로 위협하고 있다. 이러한 제반 여건들이 친수법 제정의 주요한 동기가 되었다고 한다. 그러나 친수법의 제정에는 수많은 우여곡절이 포함되어 있다. 친수법은 법안이 발의된 이래 법안의 취지를 둘러싸고 향후 법 실행과 관련된 논의가 첨예하게 대립하여왔다. 본 연구는 이미 제기된 특별법의 문제점에 대하여 법적인 관점에서 짚어보고, 그에 따른 개선방안을 모색해 보고자 한다. 친수법의 제정을 위하여 꼭 특별법이라는 입법과정을 거쳐야 했는지 그리고 친수법이 상정하고 있는 사업의 성격 및 내용에 대한 법적인 타당성을 살펴보고자 한다. 또한 친수법 제4장에서 규정하고 있는 하천관리기금을 법률 구성의 입장에서 어떻게 파악할 수 있는지에 관한 점도 고찰하였다. 즉, 친수법이 구상하고 있는 [특별법의 제정${\rightarrow}$친수구역 개발에 의한 수익 창출${\rightarrow}$하천기금의 조성${\rightarrow}$건전한 하천관리]의 구도가 법적으로 어느 정도 균형과 조화를 이룰 수 있는지 고찰하였다.

As the centralization of city, underground facilities is increasing and being more important. Although the importance of underground facilities map has been emphasized, there were many accidents related underground facilities. The inaccuracy of existing data and the carelessness of management caused many accidents. It is very important to update and to have high quality accuracy of underground facilities maps. But the underground facilities maps are mapped and updated by each institutes. So it is difficult to verify the accuracy of the data. In this study, Field Test is performed to analyze the horizontal accuracy of existing maps using Electromegnetic Induction Method, Total Station and GPS. Surveying of underground facilities in Seoul was performed for 6 institutes of underground facilities during 3 years. The aim of this study is to verify the horizontal accuracy of data and to improve the accuracy of underground facility maps. As the result of analysis, the horizontal accuracy of 6 underground facilities management institutes is 73 cm(2004), 78 cm(2005) and 75 cm(2006).

Recently, new open-cut modular construction method, which is built within a 5~7m depth below the road, was proposed for the near-surface transit system to ensure the economic feasibility of underground structures. In this paper, the precast modular construction method was developed for the low-cost and rapid construction of underground structures. For the experiment on the flexural performance of the modular slab connections, a total of eleven specimens were fabricated according to the test variables; section shape, joint type, lap length, and transverse reinforcement. The test results were compared with those of the specimens without loop joints. To verify the performance of the slab connections, the 4-point loading tests of precast RC members with loop joints were conducted. As a result of the test, the flexural performance of the half-depth specimens with a 200mm lap length of loop joints were confirmed to be similar to those of the specimens without joints.

전통적인 OD조사에 의한 OD추정의 여러 문제점들로 인해 링크관측교통량과 기존OD를 결합해 OD를 추정하고자 하는 연구들이 제시되고 있다. Yang(1995)은 일반화최소자승법을 풀기 위한 IEA와 SAB 알고리즘을 제시하였다. 그러나 두 알고리즘의 문제점은 첫째 실제 OD를 알기가 어렵기 때문에 기존 OD를 중요한 추정기준으로 설정한다는 것으로, 이러한 추정의 종속성으로 인해, 기존 OD와 실제 OD의 차이가 큰 경우 정확한 해를 도출하지 못한다. 두 번째 문제는 통행패턴 추정시 선형근사화를 가정하기 때문에 게임이론적 측면에서 전제로 설정한 완전한 Stackelberg 상황을 구현하지 못한다는 것이다. 이러한 문제점을 피하기 위해서는 기존 OD나 관측교통량의 오차에 일관적인 해도출 기법이 필요하다. OD추정 문제는 본질적으로 비선형이고 비볼록하여 전역해 탐색기법이 필요하기 때문에 전역최적화가 가능한 유전알고리즘을 이용한 OD추정모형(GAM)을 개발하였다. 사례네트워크 분석결과, GAM은 기존 OD의 오차에 대해 크게 종속적이지 않으며 OD구조가 변하는 경우에도 추정이 가능하여, 일반적으로 실제 OD를 알 수 없는(기존OD의 오차가 어느 정도인지를 알 수 없는) 도시부 네트워크에서 신뢰성있는 추정력을 보였다. 또한 기존 OD 추정모형은 비교적 용이하게 차종별로 관측할 수 있는 링크교통량을 차종구분 없이 단일차종으로 이용함으로써, 정보의 손실을 초래하여 결과적으로 모형의 추정력을 저하시켰다. 그렇지만 다차종 링크관측교통량으로부터 다차종 OD 추정연구는 거의 없었으며, 그 결과가 단일차종에 대한 추정결과와 어떻게 다른지에 대한 연구도 전무하였다. 본 연구에서는 유전알고리즘을 이용한 OD 추정모형을 다수단 OD 추정모형(GAMUC)으로 확대하였다. 사례 분석 결과 단일차종 OD추정기법은 심각한 추정오류를 범할 수 있으며, 그 적용성도 낮다는 것을 보였다. 다차종 OD 추정기법이 단일차종 OD 추정기법보다 양호한 추정력을 보였으며, 다차종 기법 중에서는 GAMUC가 IEAMUC보다 우수한 추정력을 보였다.
