Mining wastes left without any proper treatment are affecting barren or arable lands where are located near and far from source through various pathway Metals are the only hazardous constituents that cannot be destroyed or altered by chemical or thermal methods and must be converted into the most insoluble and harmless form as possible, which have slower leaching rates than the original species, to prevent their reentry into the environment. Three types of chemical additives used in this study to immobilize heavy metals showed high immobilized capacity (q) and the efficiency (k) in the order of CaO, $Na_2$S.$5H_2$O, and $CaCO_3$. In addition, bentonite was considered as a good additive to remedy AM(Acid Mine Drainage) from the results of the physicochemical characteristics and immobilizing capacity. The Freundlich coefficients (n and k) from adsorption isotherm for the heavy metals adsorbed on 50g Benlonite were calculated.

As traffic volume increases and road networks become more complicated, identifying for accurate traffic flow and driving smooth traffic flow are a concern of many countries. There are various analytical techniques and studies which desire to study about effective traffic flow. However, the necessary activity is finding the traffic flow pattern through data visualization including location information. In this paper aim to study a real-world urban traffic trajectory and visualize a pattern of traffic flow with a simulation tool. Our experiment is installing the sensor module in 40 taxis and our dataset is generated along 24 hours and unscheduled routes. After pre-processing data, we improved an open source traffic visualize tools to suitable for our experiment. Then we simulate our vehicle trajectory data with a dots animation over a period of time, which allows clearly view a traffic flow simulation and a understand the direction of movement of the vehicle or route pattern. In addition we further propose some novel timelines to show spatial-temporal features to improve an urban environment due to the traffic flow.

Smart City is the regional innovation platform that actively utilizes information and communication technologies to diversify city services and improve the performance and quality, hence improving the quality of life and creating new trends of urban activities. Recently, the importance of citizen participation is increasingly emphasized to build smart cities successfully and the Living Lab, an open innovation platform led by users, is taking center stage as a means of realizing it. Accordingly, this study aims to establish the plans for popularizing living labs that provide innovative environments for domestic smart cities. To this end, first of all, political trends related to domestic smart cities' living labs were analyzed, and then, individual characteristics and development processes of the relevant cases were investigated. In addition, in-depth interviews were conducted with the experts of specialized agencies from Netherlands, Finland, and Denmark, etc. which are considered as leading countries in smart cities' living labs. As a result, in order to popularize living labs in domestic smart cities, the following policies were proposed; establishing support systems for commercialization and dissemination, building intermediary support organizations, improvement of laws and institutions, establishing the joint response systems with neighboring areas, etc.

인간과 환경과의 관계의 역사적 변천을 인구변화와 자원관리의 측면에서 분석하는 기존 관점은 인구기초이론, 기술기초이론, 시장기초이론 등으로 분류된다. 이러한 관점은 어느 한가지 변수를 독립 변수로 가정하는 입장을 취하므로 흔히 '단일요소이론'이라고 불리며, 제각기 장점이 있기는 하지만 현실 세계의 복합성을 단지 부분적으로 설명하는데 그치는 문제점을 내포하고 있다. 현실세계의 모든 사건은 개방된 체계 속에서 발생하기 때문에, 모든 사건은 단선적인 인과관계로 파악될 수 없을 만큼 서로 복합하게 얽혀 있다. 이에 대하여 문화생태이론은 단일요소이론의 그러한 한계를 극복하고 현실세계의 복합성을 분석할 수 있는 개념과 방법을 제시하고 있다. 문화생태이론은 실로 인간과 환경과의 관계가 역사적으로 변천해 온 과정을 탐구하는데 적합한 개념과 방법을 장점으로 내세우는 새로운 관점이라 할 수 있다. 문화생태이온은 인구, 기술, 시장, 제도 등 요소의 중요성이 시간과 장소에 따라 다를 수 있다는 가정 하에서 어떠한 요소라도 어느 한 장소와 시점에서 인간과 환경과의 관계의 변화를 주도할 수 있다고 기대한다. 한국 농촌의 인간과 환경과의 관계를 탐구함에 있어서 활성되어야 할 문화생태이론의 기초적인 개념은 '지역인간생태계'와 '문화적 적응'이다. 한국 농촌의 지역인간생태계는 그 특성상 인구, 농업, 시장, 제도로 구성되어 있다고 볼 수 있다. 문화적 적응이란 변화하는 환경 속에서 사회구성원들의 환경에 대한 적응도를 높일 수 있는 행동양식을 새로이 선택하는 행위를 일컫는다. 한국 농촌에서는 적응전략이란 농업의 집약화와 상업화 또는 산아제한과 인구이동이라는 측면에서 분석될 수 있을 것이다. 생존, 기술, 취락형태, 토지이용, 무역이나 교역 등은 적응전략을 분석하는데 간접적인 자료를 제공해 줄 것이다.

Baby boomers are the population group born between 1955 and 1974 in South Korea. They are the generation to grow up in the rural areas and it has been reported in the previous literature that a large part of baby boomers now hopes to return their hometowns after their retirement. The purpose of this study is to investigate factors that obstruct the baby boomers' residential relocation to their hometowns by in-depth interviews with three different types of baby boomers: returners, soon-to-be returner, and wanna-be returner. Findings of this study show that the reasons behind the hesitation to the migration may be grouped into four categories: concerns about insufficient jobs, lack of medical services, concerns about social relation network and poor cultural environment in their hometown.

The typical unit infrastructure cost estimation techniques adopted so far in implementing the Korean Impact Fee Zoning have rather been centered around the unilateral simple cost models. The techniques, as such, have frequently been criticized for their lack of flexibility in properly reflecting the regional differences as well as the peculiarities of individual development projects. The Ministry of Land, Transport, and Maritime Affairs (MLTM), in this regard, has recently introduced an enhanced alternative technique. Using the NGIS data, the study probes the viability of the MLTM's new technique by testing the entire estimation process based on the case area in Ansung City. Reflecting the City's characteristics, the study assumes a composite land use plan that accommodates the industrial area in addition to typical residential areas. As an extensive empirical case study, the research has found from the new technique considerable technical merits to overcome the existing shortcomings and summarized its significant policy implications.
