The purpose of current tunnel maintenance system in South Korea is safety-based maintenance system for accident prevention, So it is difficult to conduct a strategic maintenance. The development of a new maintenance system can lead to effective investment of limited financial and it's effort is still in progress. In this study, to develop a performance-based assessment method, indexes for assessment are derived taking into account the safety, durability and serviceability. The indexes for performance-based assessment were selected by a literature analysis and a delphi survey. Then the importance among indexes were calculated by the AHP analysis.

본 연구는 조손가족 연구의 패러다임에 대한 문제의식으로부터 출발하였다. 인간의 존재적 역량과 선택적 자유를 강조한 Sen의 인간 존재실현력 패러다임을 조손가족 연구에 적용하여 선행연구의 시각적 한계를 극복하고자 했다. 구체적으로 조손가족 조부모의 존재실현력을 성별과 연령대별로 고찰하고, 존재실현력이 성취된 기능으로써 양육부담과 양육기쁨에 미치는 영향을 고찰했다. 이차자료를 이용한 사회조사연구로 설계했으며, 100명 조손가족 조부모의 자료를 분석했다. 분석결과, 남성 조부모는 여성 조부모보다 존재실현력의 모든 지표에서 상대적으로 높은 수준을 보였다. 그러나 연령대에 따른 존재실현력의 차이는 없는 것으로 나타났다. 조부모의 양육부담은 질병유무, 수리력, 관계의 질에 의해 유의미한 영향을 받았으며, 양육기쁨은 일상생활기술, 관계의 질, 유희역량, 재정상태의 영향을 받는 것으로 나타났다.

본 논문에서는 사학연금의 수급-부담 구조에 대한 실증자료를 제공할 목적으로 사학연금 가입연도 및 가입기간에 따른 수익비를 제시한다. 이에 따르면 전반적으로 가입시기가 늦어질수록 그리고 가입기간이 길어질수록 수익비는 감소하여 몇 차례의 사학연금법 개혁이 저부담·고급여 체계를 상당 부분 완화하였음을 알 수 있다. 더불어 저소득자의 수익비가 고소득자의 수익비에 비해 높아 2015년 개혁 시 도입된 소득재분배 효과를 확인할 수 있다. 하지만 현 제도 하에서도 사망률 감소에 따른 연금수급기간의 연장으로 수익비가 1보다 높은 것으로 나타나 연금재정에 큰 위협으로 파악된다. 다만 수익비는 그 계산에 있어 요구되는 여러 가지 가정에 따라 수치가 크게 달라질 수 있으므로 타공적연금과의 비교 시 이에 대한 각별한 유의가 필요하다. 또한 수익비는 수급-부담 구조를 나타내는 지표일 뿐 공적연금제도 본연의 기능인 노후소득보장 정도를 알려주기에는 한계가 있음에 유념해야 한다.

Securing publicness and efficiencies are the two core goals for implementing quasi-public bus system. However, researches for evaluating the quasi-public bus system with respect to the two goals have been very limited. This study represents an attempt to evaluate the system performance in these two aspects. To achieve this, a framework for performance evaluation is developed. Utilizing the framework, the 5-year performances of the quasi-public bus system in Busan are evaluated. Acess, agency and public interests are employed as criteria for publicness evaluation. Financial aspects of operators, labor, vehicle utilization, productivity and operational costs are selected as indicators for efficiency evaluation. The results show that the publicness of bus services has been vastly improved, while the efficiency has been also improved in most areas except in cost and vehicle utilization aspects. The results of this study will be of use for planners and policy-makers developing strategies for system improvement. It is hoped that this study can be further refined by adding and adjusting indicators which this study may neglect or ignore.

This study aims at finding impact of cultural and sports characteristics on urban growth. For the empirical analysis, this study uses unique urban resources associated with four categories (Social, Traffic, Cultural and Sports, and Spatial characteristics) among 228 cities and towns using a semi-log multiple regression analysis. The result shows that various local resources have significant impacts on urban growth in terms of population, industry, and fiscal self-reliance ratio. Impressively, cultural and sports resources are relatively beneficial for the urban growth. For the population and industrial growth, expanding public sports facilities and professional sports facilities can be more efficient. For solid local finance, typically focusing on professional sports facilities that have far-reaching ripple effects are useful. The conclusion for this study shows that urban growth policy should prioritize the cultural and sports resources because it can be more effective way to enhance not only for urban growth but also for quality of citizens' life.

The main purpose of this paper is to examine the structural determinants of regional variations of poverty in Korea. Poverty rates and independent variables in Seoul, 6 other metropolitan areas, and 8 provinces except Jejudo from the year of 1998 through 2006 were pooled as unit of analysis. The pooled cross-sectional time-series regression(TSCSREG) using SAS program was adapted for the analysis. As a result of the analysis, absolute poverty and relative poverty of Gangwondo and Chungcheongnamdo were relatively higher, and that of Seoul and Ulsan metropolitan area were lower than other areas. And, the increase of financial self-reliance, social welfare expenditure, rate of standard workers, and rate of workers in manufacturing sector were associated with lower poverty rates. Therefore, place-based policies should be considered as another poverty-fighting tool in conjunction with people-based policies.

The purpose of this study was to identify the differences in medical care utilization by regional economic status using the National Hospital Discharge Patients Injury Survey. In order to determine economic status of each region, 234 cities and counties were categorized 5 quintiles according to their financial self-reliance ratio. The main results are as follows. First, low economic region has high age-standardized admission rate and standardized mortality rate. Second, of 16 major diseases, cerebrovascular and heart diseases, lung cancer, and stomach cancer reported greater changes in standardized mortality rate by regional economic status. Third, the rate of admission via emergency room in low economic region is higher than that of high economic region. Lastly, in the major illnesses, lower economic status led to an increase in average length of stay. Therefore, In order to bridge the gap in health inequality across regions, a regional medical policy tailored for each region and characteristics of the economic status should be established.

This study investigates how much building area among total building area concentrates on urban region in a local government region and then, I applies 'The Index of Building Concentration in Urban Area' for the first time in a study. The finding shows that Cities' Index is higher than counties', and also shows that a lower index is associated with a higher rate of older adult population, and is also associated with higher general budget expenditure by the local government based on the index of Building Concentration in Urban Area in Gyeongbuk Province. This study provides evidence that the Index of Building Concentration in Urban Area can be utilized in measuring shrinkage level, effectiveness of municipal finance, and in establishing shrinkage city/county planning by basic data.

In many cases, operation of regional trunk lines is not profitable to railway operators. Nevertheless, railway operators are under pressure to manage regional trunk lines running under deficits, to better serve public interests. Given this situation, railway operators need to optimize assets by adjusting train schedules or changing the number of trains running. When railway operators judge the operation of a regional trunk line, the B/C ratio is generally used as a management index. This ratio is not considered part of strategic operational policy over the long term, and excessively influenced by the aspects of supply and demand over the short term. Accordingly, this study focused on indices that might be used to prevent worsening deficits and provide long term strategic operation policies, main indices to better measure economic situations, and auxiliary indices to supplement the main index. The main indices were measured in conventional ways to target experts and employees. This study presents quantitative standards, which are intended to be used to create itemized criteria through an Analytic Hierarchy Process, for better decision-making.
