In recent years, mary studies for efact estimation of groudwater recharge has been performed. They can be categorized into three groups : analytical method by means of groundwater recession curve, water budget analysis based on watershed, and the method using groundwater model. Since groundwater recharge rate shows the spatial-temporal variability due to hydrogeological heterogeneity, existing studies have various limits to deal with these characteristics. The method of estimating daily recharge rate with spatial-temporal variation based on rainfall-runoff model is suggested in this study for this purpose. This method is expected to enhance existing indirect method by means of reflecting climatic conditions, land use and hydrogeological heterogeneity.

The global economic recession caused a great change of the labor environment such as restructurings and unstable employment. This facts brought about an increase in sense of rivalry, over workload, job uncertainty and lowering of self-confidence. Due to the fact that the work process and employing system in construction field is little differ from normal industries, especially, labors working in construction field are much exposed to the job stress. On this study, we survey construction-field labors and made an analysis of the gathered data through the statistic method to reveal what kind of job-stress factors influence on the defects of construction works. As the result, we investigated the truth of the induction factors which cause the job-stress in costruction field and proposed an alternative plan for an effective job-stress management which make the defect rate low.

Each nation of the world is intensively propelling the R&D investment to solve the financial crisis and worldwide economic recession occurred from last year. This means the world economic is under economic system based on the knowledge. So, The R&D is continuously propelled for possession of the technology through the R&D stock and which is core in the knowledge based economic system. In this world stream, our government is also increasing the R&D investment and checked the technology level through surveying the R&D stock and corn parison of each industry or world. The R&D investment of the railroad is continued but there is no data of the R&D stock. So, surveying the railroad R&D stock and comparing with korea industry is processed.

In this prolonged economic recession, the countries in Northeast Asia play a crucial role in the global market and the relationship between Korea and China gets more attention due to its significant achievement during the past 20 years after the establishment of diplomatic ties in 1992. In this regards, this study presents general overview of Korea-China Car Ferry Route and evaluates the efficiency level of each operating route using DEA model. Incheon-Yingkou, Incheon-Lianyungang, Pyeong Taek-Lianyungang are analyzed as efficent routes, while from the view point of passenger efficiency, 4 routes i.e, Incheon-Dalian, Incheon-Dandong, Pyeong Taek- Weihai, Gunsan-Shidao are also noted as efficient routes. Consequently, other inefficient routes can benchmark these efficient routes by increasing cargo volume and passengers.

이 연구는 남한강유역의 월강우량과 월유출량을 추계학적 및 통계학적으로 분석하여 두 개의 시계열 모형식을 설정하였다. 월유출량의 시계별 모의기법은 모의합성하는 월유출량자료로 선형추계학적 모형을 유도하였다. 또한, 월강우량과 월유출량의 시계열모열은 기지 통계학적 변수를 갖는 임의 시계열이라 하여 유도하였으며, 이는 월유출량이 한 변수를 갖는 지수감소곡선의 특성과 이월기간에 대한 통계학적 변수로 전개되었다.

London's BID, introduced in the early 2000s, has grown significantly to fill the gap between government services which have been decreased by the global recession and localism, and the demand for better services to strengthen competitiveness on a global level. Based on this background, this study comparatively analysed two BIDs in London with contrasting regional characteristics to find how BID works differently for the regeneration and sustainable development of regional business districts according to regional characteristics. As a result, the two BIDs ultimately had the goal of improving the local business environment and strengthening the competitiveness of local businesses and had a common point of working in close partnership with the public sector such as the local government. However, depending on the local situation and characteristics, it has been observed that there are differences in the strategies of work and the roles and relationships in the partnership with the public sector.

The purpose of this study is to fully understand the present state of the domestic construction companies, and to analyze phased business types and construction management techniques in order to initiate overseas expansion. Because of the recession in the domestic construction market, a thorough and strategic perspective to constantly develop inroads into overseas market is required. So we carried out a questionnaire survey targeting the experts of the overseas construction and researcher, and consulted them in depth. The questionnaire survey was divided into three sections. The first section is the necessity of overseas construction and the reason. The second is the overseas business types classified into the way of advance in short-term and long-term phase possibility of expansion. Lastly, the importance of the phased construction management techniques and the current capacity of the domestic and the foreign business trends were scrutinized. On the basis of the consultation and surveys, we analyzed the overseas business types and the construction management types in the short-term and long-term phase.

항만연관산업과 최저임금간의 생산성 및 고용효과에 대한 상관관계를 분석한 결과, 그 효과는 매우 미미한 것으로 나타났다. 그러나힝민연관산업의 상용근로자와 임시근로자, 자영업자 및 기타 근로자에 대해서는 다소 차이를 보이고 있다. 즉 상용근로자는 다소 안정적인 반면에, 임시직과 자영업자에게는 다소 부정적인 효과를 미치는 것으로 나타났다. 최저임금위원회에서 최저임금의 인상은 노동시장에서 소득효과와 대체효과 간의 상호작용에 의하여 안정적인 모습을 보이고 있다. 항만연관산업은 최저임금 인상이라는 변수보다 오히려 세계적인 경기불황, 국내 경기의 변동성에 더 영향을 받는 것으로 분석되었다.
