  • This study aims at developing environmental indicators to evaluate sustainability of district unit planning in Seoul. The indicators are devised to evaluate three categories of influencing areas such as district planning area, surrounding areas of planning area, and city wide area. In order to formulate the environmental indicators, subsystems of the environment were reviewed and classified into seven sectors of the environment such as air and climate, soil, water, green space, fauna, noise, and landscape. 16 indicators were developed from the seven sectors. Weighing were given to each indicator resulting from AHP analysis of the questionnaire survey of environment and urban planning experts.

  • Developing reliable measures of the environment is important to increase our understanding of the environmental effects on walking among seniors. As a preliminary study for developing an instrument for measuring walkability of seniors' environment, the purpose of this study are to identify important assessment indicators associated with seniors' walking and to test their reliability using inter-rater and intra-rater reliability methods. A set of assessment indicators was identified through literature review, and field studies by trained raters were conducted in three senior centers located in Seongnam area in order to test reliability of the audit tool. The results indicated high percent agreement for most indicators and overall 91.6% and 86.1% of items assessed had good or medium inter-rater and intra-rater reliability, respectively. The reliable assessment indicators would provide reliable data for use in community-based audits of built environment in relation to walking among older adults. The findings showed that the indicators of aesthetics had lower reliability compare to safety, convenience, and access. Rater training with various images would improve rater agreement while reduce rater bias.

  • An ecosystem-based fisheries management (EBFM) approach becomes more important as an alternative management method for a sustainable development of fisheries domestically and internationally. Many methods of applying a practical EBFM to fisheries management have been investigated, and considerable attention has been given to developing effective indicators of the present status of and changes in ecosystems and putting them to practical use. Among ecosystem indicators, developing socioeconomic indicators for EBFM is particularly important. This is because socioeconomic factors have direct effects on ecosystems, and ecosystems have direct effects on socioeconomic factors. Therefore, it is imperative that socioeconomic indicators are developed and evaluated in order to predict changes in ecosystems and to provide advice for effective fisheries management. This study is aimed to develop socioeconomic indicators which can be combined with biological and ecological indicators, in order to conduct the ecosystem-based fisheries assessment. In terms of socioeconomic indicators, five socioeconomic criteria were considered as important attributes of socioeconomic changes. These criteria include economical production, business conditions, income, market, and employment indicators. For evaluation of newly developed socioeconomic indicators, the Traffic Light System (TLS) method was used. In addition, on the basis of the application of developed indicators to the Korean large purse seine fishery, the socioeconomic conditions of the fishery and the usefulness of the indicators were evaluated and management implications were discussed.

  • This study aims at choosing indicators to measure the effect of utilizing biotop map, and analyzing its effect by an indicator from the perspective of performer. The Primary performance indicators are made through specialist survey using SMART. As a result, three indicators are chosen: "Discussion of the period of an environmental effects evaluation(reduced effect)", "Plan and execution of environment and ecology plan in an urban development site", "Minimizing ecological damage in an urban development." The result in each indicator is as follows. The indicator of discussion of the period of an environmental effects evaluation(reduced effect), the average reduction rate in statistically meaningful level reduced 6.08% and 11.64% respectively in 2004-2005. In this period, environment information system was established and the reduction effect is shown in this period by reinforcing environment effect estimation using biotop map. As to the indicator of utilizing biotop map in an urban development site, the Seongnam P site case shows that biotop map was used when they set up an development plan. In case of minimizing ecological damage in an urban development, the Gwangjingu G-dong case shows that it was used to appoint preservation sit, and mediate development restrict area. Accordingly, the biotop map utilizing effect is confirmed through core performance indicators and verification of the indicators using SMART. The further research is encouraged to find evaluate indicators and verify the effect quantitatively to increase the use of biotop map.

  • The purpose of this study is to establish common indicators that constitute a "low-carbon green city" and determine their priorities from the perspective of Incheon Metropolitan City with a view to help develop its climate change strategy strategic city. Several major cities, domestic and overseas, were benchmarked to come up with preliminary indicators consisting of six areas, twenty two planning factors, and 74 indicators. In order to evaluate the validity and relevance of preliminary indicators, expert FGI (Focus Group Interview) was conducted that changed the numbers of final indicators to six areas, twenty two planning factors, and 82 indicators. Finally, AHP (Analytic Hierarchy Process) was conducted to assign relative importance (i.e. weights) to each indicator. Through the layering process of AHP, the upper category of "field" and lower category of "planning factors" were set up as policy prerequisites for constructing a low-carbon green city (6 fields, 22 planning factors). The AHP results for the first level (fields), green city space was ranked first, followed by energy and resource circulation, green traffic, ecological preservation, green logistics, and governance. Among all planning factors, land use, energy efficiency, traffic system improvement, location planning, securing of ecological area, efficiency of logistics, and cooperative organization showed the highest priorities.

  • The purpose of this study is to establish a system to evaluate the ecological soundness of the Geum river basin. The study target area is 14 sub-watersheds of the Geum river basin. For the selection of indicators to ensure transparency and consistency of the evaluation indicators, the ecological soundness indicators were secured by using the indicator adjustment method derived in consideration of the intrinsic weight change characteristics between indicators. The index with the greatest impact on the final composite index was identified as the index of the aquatic ecology among the water quantity, water quality, aquatic ecology, and habitat-riparian environment dimensions. As a result of analyzing the ecological health index of the river, the watershed upstream of the dam (based on the Daecheong -dam) was evaluated to be in relatively good condition until 2014 compared to the base year(2008), and the watershed downstream of the dam was evaluated to be in a poor condition. The annual trend of changes in the ecological soundness index on an annual basis is as follows. In the case of Yongdamdam, Yongdamdamdownstream, Bocheong-chun, Daechungdam, Daechungdamdownstream, and Nonsancheon, although there are differences by time period, the soundness index is in declining. On the other hand, Mujunamdaecheon, Yeongdongcheon, and Gapcheon were evaluated to have improved soundness, while Chogang, Daechungdamupstream, Mihocheon, Gongjugeumgang, and Geumgangestuary were evaluated to deteriorate again after soundness was improved.

  • Background and objective: The vitalization of urban agriculture has increased various forms of experience-based education using school gardens, which raised the importance of school gardens in terms of value as well as the need to develop an implementation system for education-based agricultural experience service using school gardens. Thus, we reset the evaluation indicators from the previous study to establish objective evaluation indicators that enable quantitative comparison of school garden education services. Methods: Analytic hierarchy process (AHP) and direct question (DQ) surveys were conducted on 20 experts from October 12 to 19, 2020 after establishing the purpose and subjects of evaluation, and then the weights were calculated using the Expert Choice 2010 program. Results: First, we analyzed the problems of the previous indicators by categorizing the performance indicators and comparing and verifying them with six requirements of valuation. Then, we added 'welfare values' and established sub-indicators accordingly. The importance of value indicator in AHP was in the order of education values (0.544), health values (0.182), welfare values (0.164), environmental values (0.062), and economic values (0.049). The importance of environmental and economic values was relatively low, less than 0.1. The importance of sub-indicators was highest in cultivating character (0.144), followed by enhancing ecological sensitivity (0.141) > promoting mental health (0.134) > cultivating agricultural literacy (0.120) > improving social skills (0.104). And mitigating climate change in environmental values was lowest (0.009). Increase in income was the lowest (0.036). This can be regarded as the expression of change to increase the educational effect based on collective life and the connotative meaning of 'school'. In the case of DQ, the AHP weight and order were the same, but the environmental and economic values were relatively low, and the result was different from AHP weight. For sub-indicators, the importance in DQ was highest in promoting mental health (0.136), followed by promoting physical health (0.085), ]cultivating character (0.082), social integration (0.072), and enhancing ecological sensitivity (0.071). After reviewing related experts, we came up with 5 evaluation indicators and 16 sub-indicators for school garden education service, which are objective evaluation indicators that enable quantitative comparison. Conclusion: In the future, we will validate the socioeconomic values of school garden education services and contribute to revitalizing school gardens by establishing policy alternatives for effective operation and management of school gardens.

  • Through the harmony of natural and artificial systems a city is composed of, the ecology-oriented urban planning seeks for qualitative improvements of a city on which our life is based. To enhance the ecology-oriented urban planning, the followings are suggested by a comparative analysis of Korea with Germany regarding the development process, the instruments, and the establishment of indicators for the planning. Firstly, though our national land development plan is closely connected with B-plan, it has little to do with the natural environment. Moreover, the natural environment plan of the Ministry of Environment is almost impossible to carry out in terms of urban construction work. For this reason, the instrument for dealing with the development and environment plan systems together as well as the completion of the current plan system is needed for the ecologically acceptable urban development in the long term. Secondly, in order to realize what is mentioned above in the concrete it seems to be desirable for the system and the instrument to be devised at the extent of B-plan. The regulations of the plan should have strong legal binding force and practicality as well. The element of ecology-oriented urban planning are (1) degree of independence and appropriate density, (2) conservation of natural elements such as soil, water, animals and plants etc., (3) energy saving in land use, (4) activation of B-plan and inducement of active participation of residents. Thirdly, it will be useful to develop various kinds of indicators for the environment plan provided in advance so that the ecology-oriented urban developments may be under control. It also should be taken into consideration that the indicators are supposed to be comprehensive, representative, and practical enough to make the most of at the early stage of drawing up a plan. The kinds of indicators which can be used in the ecology-oriented urban development include (1) soil, (2) water, (3) vegetation and plants, (4) animals, (5) climate, and (6) transportation.
