Various researches and practices on asset management and asset-based mapping have been done with regard to engineering, industry, business and stocks marketing areas. Their notions and concepts are differently interpreted in response to different requirements. There are considerable research outcomes of management, operation and maintenance for physical, natural and digital assets. However, existing concept of asset management might have limitations to deal with diverse tangible or intangible assets at the individual/household/community level. In this paper, a conceptual framework of Hexad asset model is designed to explicate increase, decrease and other changes of assets flows as a geometric pathway. Particularly, consideration of lands and housing as important physical and natural assets to escape poverty not only leads to creation of an excellent 3D digital asset management, but also reaches to a new approach to asset-based mapping for a poverty information management and system.

Estimation and indication for spatial distribution of living quality and poor condition associated with land and house`s access as a basic human need has been imperative questions and predicaments while it is required to boost digital economic development and consolidate social maturity. Although modern IT and sophisticated GIS/LIS technologies are used to examine spatial analysis of population location-patterns, land uses and development, and environmental degradation, etc, it still might remain immature step to figure out the causations and results of poverty in space and time. In this research, a new approach to poverty management is explicated by using 6 parameters as a major tool for assisting poverty monitoring concerning the poor who are very unpredictable in space and could be regarded as renegades in the Internet age. In addition, it expounds a new approach and conceptual idea for poverty management to notify spatial location of the digital divide when poverty reduction is closely concerned with sustainable goal of land information.

Building the capacity for climate change from low carbon development and energy GIS

In the midst of global emerging issues for climate change mitigation and adaptation, the concentrations on capacity building (CB) and capacity development (CD) have been seriously highlighted in recent years to tackle negative impacts of greenhouse gas emissions (GHG) and environmental degradations at the municipal and national levels. CB and CD approach to climate change would be regarded as the development or strengthening of personal skills, expertises, and relevant institutions and organizations to reduce GHG emissions and to minimize vulnerability to climate-related impacts. There are, however, still ambiguous aspects of CB and CD as to how climate change"s experts and specialists in the UNFCCC, UNE(D)P and GEF could translate multi-dimensional natures of capacities into a specific heart of carbon emission"s reduction and low carbon development without slacks or discontinuity of sustainable development. The paper expounds international views of CD in association with low carbon developments and proposes an innovative model for climate change sustainable capacity development. In addition, a technical approach to carbon emission"s reduction is creatively designed to build the capacity in sustainable low carbon development. It especially shed light on universal characteristics of mitigative and adaptive capacity for a conceptual climate change framework based on sustainable energy and carbon management system.

Modeling Community Capacity Building Using Spatial Asset Mapping

지역사회능력 (community capacity) 개념은 사회경제, 환경 그리고 물리적 배경의 발전지표 및 인자와 연관된 사업을 하는 지역사회 및 지역주민의 능력으로 간주된다. 지역사회발전계획과 관련된 문제점을 효율적으로 분석하는 지역사회의 능력배양은 지리정보시스템을 이용하여 인프라 및 사회경제의 능력향상에 대하여 떤 상태를 조사요구 한다. 지역사회의 능력을 증가시키는데 있어 계획된 자산형성의 노력은 지역발전의 일부분으로 볼 수 있다. 공간자산매핑(spatial asset mapping)은 유루형의 자산목록을 만들고 확인하는 일련의 과정이다. 이러한 자간매핑은 인적, 사회문화적, 자연적, 금융적, 디지털적 및 물리적 능력에 관하여 개인, 공동체 그리고 지역사회가 지닌 능력을 조사하며 발전시키는 것을 필요로 한다. 이 연구 목적은 능력배양(rapacity building)의 새로운 개념을 제안할 뿐만 아니라 독창적인 자산기반으로 하는 지역사회능력배양의 개념적 모형을 일필지 중심의 공간자산매핑 및 능력매핑과정을 통해서 제시코자 한다. The concept of community capacity is regarded as the ability of people and communities to do works associated with the determinant factors and indicators of the circumstances of socio-economic, environmental and physical contexts. Building capacity of communities to effectively analyze our problematic issues and planning of community development is often required to scrutinize current status of community of socio-economic and infrastructural capacity development with GIS. We consider community development as a planned effort to build assets that increase the capacity of communities. Spatial asset mapping is the process enabling to identify and make inventories of tangible and intangible assets. This mapping requires developing a capacity inventory that collects indivic organizational and community capacities in view of human, socio-cultural, natural, financial, di, and physical capacity. The purpose of this research is not only designed to suggest a new cone capacity building, but also proposes a more creative framework of asset-based community cap linking to parcel-based spatial asset mapping and capacity mapping process

Supporting Geo-Workflow Management through Object Activity Model

Liou, Jaeik,Ryu, Keun Ho 한국지리정보학회 2001 한국지리정보학회지 Vol.4 No.2

지형정보 작업관리(워크플로) 연구는 중요한 관심이 되는 분야 중에 하나로 시간변화에 따라 발생하는 사건, 행위 그리고 프로세스들의 상호작용 및 변경 등을 처리할 수 있는 방법 및 모델이 요구된다. 기존의 많은 워크플로 프로세스 모델이 있지만, 육하원칙에 의거하여 행위자의 시간과 공간적 행위 또는 사건을 해석하려는 시도가 많지 않은 듯하다. 이 연구는 6가지의 조건을 조사하고 객체지향적인 헥사드 행위 모델을 제시하여 지형정보 프로세스 및 행위를 분석하고자 하였다. 행위자의 다양한 행위의 원인과 결과를 시공간 개념과 연계하면, 육하원칙의 자세한 분석은 공간의 변화나 공간정보 흐름을 파악하는데 상당한 도움이 된다. Management of geo-workflow's changes is one of growing issues and requires more advanced ways and methods to deal with heterogeneous modifications and interactions of process, activity and event over time. A few dominant workflow models have coped with these subjects. There is, however, little consensus for explanation of six dimensions with regard to actor, activity, space, time, reason and effect. This study begins with examining environments of six dimensions and the Hexad model is proposed to elucidate the causes and results of a wide variety of geo-processes and activities. In this paper, we will introduce Hexad Object Activity Model making it possible to interpret manifest motivations, conditions and actions. Full descriptions of six dimensions are often useful for applying to the handling of diverse activities particularly requiring to clarify actor`s goal and role at a specific time and space.

Coagulation is a very important process in rapid filtration system for effective removal of turbidity and organic matters in the sequential sedimentation and filtration processes. The purpose of this research is to find both coagulant consumption factors and to determine coagulant dosing equation with characteristics of water. Many coagulation factors are proposed such as pH, alkalinity, TOC, temperature, velocity gradient, mixing time, among these factors we have studied on the alkalinity and natural organic matter (NOM) as humic acid in pH 7.0∼7.5 value using two different coagulants; poly sulfate organic-magnesium (PSO-M) and poly aluminium chloride silicate (PACS). The results for coagulants consumption rates with alkalinity and NOM concentration showed that the dosing equation of PSO-M and PACS is as 10^((0.722log(alk)+0.00497)), 10^((1.06log(alk)-1.0)) for alkalinity and 6.1 ㎎/1, 5.l㎎/l for NOM, respectively.
