This study investigates the level of elementary school parents' satisfaction and recognition on the education gap between the eastern and western part of the Busan Metropolitan City. The gist of the discussion centers on the equal educational opportunities of the schooling, non-schooling. To accomplish this research, we practice the questionaries about the education development in Busan to 234 parents who reside in the eastern and western part in Busan. The results of survey are as follows. First of all, there is a broad distinction between the two area about parents' attitude towards children. Second, the results of schooling satisfaction are higher in eastern Busan area. Third, the parents of eastern part also show their satisfaction of schooling support. The results indicate that nation and local government must develop the short and long range plan for students from low-income families.

최근 수도권 중심의 생활권역 확장과 대도시로의 인구 집중으로 도시 내의 교통 혼잡이 지속적으로 증가하고 있다. 도심지의 땅값 상승과 한정된 부지로 인해 새로운 도로 건설은 불가능하게 되었고, 데이터 기반의 효율적인 도로 운영의 중요성이 점점 부각되고 있다. 효율적인 도로 운영을 위해서는 교통상황의 변화에 따른 적절한 TOD 시간분할과 TOD 시간분할을 통한 최적의 신호 운영 방안이 필수적이다. 본 연구에서는 최적의 TOD 시간 분할을 위해 연속된 교차로에서 수집된 교통량과 속도 데이터에 시계열 데이터의 군집 분석을 위한 동적 타임 워핑 모델을 적용하였다. 시간 분할을 위해 활용된 데이터별 군집의 특성을 분석하여 최적의 신호 운영 시나리오를 구성하기 위한 시간 분할 방법론을 제안하고자 한다.

본 두 편의 연속논문은 수도권과 비수도권의 갈등관계를 조절하고 상생전략을 구체적으로 실현하기 위한 수단으로서 수평적 지방재정조정제도 이용방법을 제시한다. 본 논문에서는 먼저 수도권 정책을 둘러싼 선행연구를 비판적으로 검토한다. 수도권의 경제적 이점, 정책방향 및 대도시권의 역할 등을 둘러싸고 양극단의 대립적 견해가 구조적으로 고착화 되고 있지만 상생발전에 대해서는 수사적 제시만 있을 뿐 구체적인 실천수단을 제시하지 못하고 있다. 하나의 대안으로서 한국에서 아직 도입하지 않고 있지만 동일 수준의 지방정부간 재정이전을 동반하는 수평적 지방재정조정제도는 효과적인 상생발전 구현수단이 될 수 있다. 독일, 영국, 프랑스, 스웨덴을 중심으로 외국의 수평적 지방재정조정제도의 기본이념과 논리적 준거 및 조정방법을 살펴보고, 한국 지역정책에 갖는 시사점을 제시한다.

The purpose of the paper is to examine the nature of population distribution during the past 25 years; to evaluate effect of population redistribution policies which have been adopted by the government; and to suggest desirable future policy directions. The distinctive features of population distribution during the period of 196O~85 can be summarized as progress of rapid urbanization, decrease of absolute number of rural population and heavy concentration of population in the Seoul metropolitan area which have resulted in population maldistribution among regions. The problem of population concentration in the selected one or two large urban centers was first recognized by the government as early as in 1964. Since then numerous policy measures have been adopted to reduce the population concentration into the Seoul metropolitan area and thus to guide a sound population redistribution among regions. The overall assessment of various policies on population redistribution, however, revealed that the effect of the policy efforts has not been great as they originally anticipated. Various reasons can be cited for the failure of the past policies. Among them the followings were frequently mentioned; lack of integration among policy measures; weak linkage between relocation and accommodation; and non-existence of single authority for overall implementation of the polices. Based on the past experiences the followings are suggested in pursuing future policies. First, the short-term objective or target should be clearly defined. Second, policy measures have to be designed to go with rather than against market forces. Third, indirect incentives or aids are more effective than direct controls or regulations. Fourth, local participation has to be secured in every phase of policy formulation and implementation.

The Metropolitan Tracer Experiment (METREX) was performed over the Washington, D.C. area using two inert, non-deposition perfluorocarbon gases for over 1 year period (November 1983∼December 1984). Two perfluorocarbon gas tracers (PDCH, PMCH) were released simultaneously at intervals of every 36 hours for 6 hours, regardless of the meteorological conditions in metropolitan area. Samples were collected continuously for 8 hours at a central downtown and two adjacent suburban locations. Monthly air samples were collected at 93 sites across the whole region (at urban, suburban, and rural locations). The purpose of this study is to simulate INPUFF and ISCST model using METREX data, and to compare calculated and observed concentrations. In the case of INPUFF simulation, two meteorological input data were used. One is result data from wind field model which was calculated by diagnostic wind model (DWM), the other is meteorological data observed at single station. Here, three kinds of model calculation were performed during April and July 1984; they include (1) INPUFF model using DWM data (2) INPUFF model using single meteorological data (3) ISCST model. The monthly average concentration data were used for statistic analysis and to draw their horizontal distribution patterns. Eight-hour-averaged concentration was used to describe movement of puff during the episode period. The results showed that the concentrations calculated by puff model (INPUFF) were better than plume model (ISCST). In the case of puff model (INPUFF), a model run using wind field data produced better results than that derived by single meteorological data.

This study measured technology transfer efficiency for public institutes. The study made use of DEA being one of the non-parametric linear programming to evaluate technology transfer efficiency for public institutes and to measure technology efficiency, pure technical efficiency and scale efficiency. The measurement of the technology transfer efficiency for public institutes was as follows: The cause of the technology transfer inefficiency was affected by pure technical inefficiency more than by scale inefficiency. Public institutes' RTS(Return To Scale) value varied depending upon the features of the organizations than the features of the regions. Public research institutes' RTS value is more effective than universities' RTS value. We compared the RTS group with the RTS of Projected DMU groups. The RTS group had constant returns to scale effect while the RTS of the Projected DMU had increasing returns to scale effect. The technology transfer efficiency of public institutes varied depending upon the features of the organizations and regions : The technology transfer efficiency of public institutes were as follows : public research institutes at the metropolitan area, public research institutes at the local areas, universities at the metropolitan area and universities at the local areas. In other words, the technology transfer efficiency was affected by organizational characteristics more than by regional characteristics at the place where public institutes were located.

The purpose of this research is to analyze the wealth effects of home-owning baby-boomers on household consumption on non-durable goods in the Seoul Metropolitan Area. In so doing, this empirical study utilized the Korean Labor and Income Panel Study (KLIPS) of 2002 and 2012. The statistical findings reveal that household wealth in the period had sharply risen in household income, asset, debt and consumption, and the substantial increase came from growing income and consumption embedded into an expansionary stage of the family life cycle. Further, housing wealth had a much greater effect on consumption expenditure than did financial asset in 2012 while financial wealth effect was larger than housing wealth effect in 2002. Housing wealth effects had become far stronger as the age of the baby-boomer householders increased. As the baby-boomers are close to the retirement stage, post-retirement income security becomes of concern, so that the wealth effect of real estate income as an income alternative for retirees is explicit. The results imply that retirement of baby-boomers is likely to reduce consumer spending, aggravating slowdown of the real economy. Thus, diversification of household asset portfolio in a pre-retirement period is of great significance in maintaining adequate household consumption in later life.

서울온수산업단지는 준공한 지 50년이 넘은 노후산업단지로, 산업단지 기반시설과 공장 건축물의 노후화가 진행중이다. 그럼에도 불구하고, 현재 서울온수산업단지에는 기계 산업 중심의 도시산업 집적이 발생하고 있다. 이 연구의 목적은 노후산업단지의 물리적 시설 노후화와 산업 집적 특성을 종합적으로 분석하여 서울온수산업단지의 정체성을 도출하는 데에 있다. 연구 결과, 서울온수산업단지는 수도권에 집중된 거래 네트워크, 소필지화로 인한 영세기업의 입주, 소음 유발 공정의 허용, 고숙련 기술자 확보 용이성에 따라 도시산업 집적이 강화되고 있다. 그러나 이 집적은 산업단지 생산기능의 약화, 입주기업의 제한된 혁신성, 수도권 기계 산업경쟁력 약화에 따른 비혁신적 특성이 공존하는 것으로 나타났다. 이를 종합하면 서울온수산업단지의 정체성은 '비혁신형 도시산업 집적지'로, 수도권 중심의 기계 산업 네트워크에 기반한 비혁신적 집적이 발생하고 있는 노후산업단지이다.

This research is based on self-filling survey which 656 dental hygienists who work in, seoul, the metropolitan area, jeon-buk area participated on July 2006 through August 2006. This survey was analyzed the relationship between the subjective symptoms(6 types) and outdoor air quality($O_3,\;NO_2,\;CO,\;SO_2,\;PM_{10}$) As follows analyzed results. The health condition of dental hygienists were "Feel Good" more than 50% in last month. The experience the symptoms level is higher then non-experience level in "Dry eye, itch, smarting", "Headaches", "Fatigue and sleepiness", "Red eye", "Hypersensitivity", "Dorsalgia, omarthralgia, cervicodynia". We anticipated that the more experience the subjective symptom the more likely it is that outdoor air quality will be high rate level. But we could not find the uniformity in metropolitan-area and seoul-area. In the case of jeonbuk area, the group's pollution density levels which experienced the subjective symptom were appeared high rate than inexperienced group except $SO_2$. It probably comes from sensibility for an air pollution in this area. Dental hygienists who work in jeonbuk area have an unusual sensibility for an air pollution because outdoor air quality of jeonbuk area was rule good rather than others area. especially $SO_2$ was revealed out even though low rate level in inexperienced group it is that the number of cars in jeonbuk area is increasing rapidly.
