  • Urban green spaces supply ecosystem services (ESs), which are consumed by city residents and generate demand, to improve air quality. It is important to determine supply and demand for ESs and reduce the gap for efficient management. This study proposed a method to use the concept of supply and demand for ESs in the decision-making process for urban planning or management. PM10 concentrations were converted to weight for demand assessment on PM10 reduction, and PM10 absorption capacity of all green spaces including the forests, and that of urban green spaces excluding forests, was calculated for each supply assessment. The differences in the calculated supply and demand were analyzed to derive the mismatched regions in Suwon. As a result, regions with big forested areas showed sufficient supply, indicating that the degree of mismatch among administrative neighborhoods (dong) varied greatly depending on whether they had a forest. An analysis of only urban green spaces showed that all neighborhoods lacked supply. Forests with high PM10 absorption capacity had a great effect, but urban green spaces can be considered a key element in reducing PM10 in daily life. Considering the mismatch of supply and demand, spatial distribution, and population distribution, it is possible to prioritize the supply of urban green spaces to reduce PM10 and, furthermore, support decision making for priority zones subject to forest conservation and designation and cancellation of green spaces, which gives significance to this study.

  • VTS 협력항해는 수많은 상황판단과 자율적인 행위자들의 의사결정들의 집합체이다. 선박이 서로 영향을 끼치며 상호작용하기 때문에 발생하는 불확실성이 바로 VTS 협력항해가 해결해야 하는 문제 상황이다. 이러한 불확실성으로 인한 항해위험을 극복하기 위해서는 상황자각과 의사결정이 항해사 개별 차원에서 뿐만 아니라 모든 항해자들이 서로 도우면서 VTS 협력항해 전체적인 차원에서 이루어져야 한다는 점을 중점적으로 논의하였다. 본고에서는 해양사고의 원인으로서 조선기술의 미숙보다는 항해관련 인지기술이 더 직접적으로 작용한다는 점을 주장하면서, 더 나아가 기왕에 발생한 해양사고를 상황자각 관점에서 접근함으로써 해양사고의 인적과실과 관련한 심층적인 분석을 할 수 있다는 것을 밝혔다. 항해의 인지과업을 1단계 상황자각에서부터 분산의사결정에 이르는 과정으로 세분화하고, 이런 관점에서 접근함으로써 해양사고의 원인으로 작용하는 인적과실을 심도 있게 분석할 수 있었다. 인지과업의 세분화를 통해서 항해사들이 각 단계별로 에러를 수정할 수 있는 여유를 확보할 수 있게 하고, 사고로 이어지는 인과 고리를 차단하는 한편 보다 안전한 대안을 찾아 실행할 수 있다는 점을 부각시켰다. 이런 연구결과를 항해사의 훈련 과정에 접목함으로써 해양사고의 위험을 획기적으로 줄일 수 있다는 것을 밝히고자 노력하였다.

  • A major goal of the Community Plant Food Project is to develop partnerships between the Cornell Community Nutrition Program and Community-based organizations, including Cooperative Extension. A core principle behind this work is integrating research and intervention. Based on our work in Rochester, New York, we have developed a process and principles for effective partnerships. This new paradigm what we call the University-Community Partnership Model is a team effort that builds on the experiential literature in the fields of communication, leadership, community and team development, sociology, and participatory research and action. We have applied this model both to increase our understanding of Family Food Decision-making and to develop programs for families. In this project, we have used a variety of qualitative methods to understand food decisions from the perspectives of families and community stakeholders, including a group method for analyzing our qualitative interview data. For our survey of families, we developed the Enhanced Response Method, an approach for improving the validity and reliability of community surveys with families and, at the same time, building relationships with families and other stakeholders in the community for integrated and sustainable interventions. Because the knowledge we develop through the partnership and the interventions we seek to implement are products of the process, we are constantly seeking to refine this knowledge and to adapt emerging interventions through an ongoing evaluation process we call the Continuous Improvement Method.

  • Company A's core competency is IT internet security services. The Web diagnosis team analyzes the vulnerability of customer's internet web servers and provides remedy reports. Traditionally, Company A management has utilized a simple table format report for resource planning. But these reports do not notify the timing of human resource commitment. So, upper management asked its team leader to organize a task team and design a visual dashboard for decision making with the help of outside professional. The Task team selected the web security diagnosis practice process as a pilot and designed a dashboard for performance evaluation. A structural design process was implemented during the heuristic working process. Some KPI (key performance indicators) for checking the productivity of internet web security vulnerability reporting are recommended with the calculation logics. This paper will contribute for security service management to plan and address KPI design policy, target process selection, and KPI calculation logics with actual sample data.

  • This study discusses two canceled dam projects, Youngwol Dam in South Korea and Two Forks Dam in Colorado of the United States. Both of them illustrate how the new paradigm applies to regional water projects because they became victims of environmental opposition in the new paradigm. While the cases have no apparent close relationships and they occurred in different decades, they offer interesting comparisons. They were basically struggles between water development coalitions and environmental protection coalitions on regional water conflicts. The two proposed projects brought about fierce debates on large dam as they embraced a wide-range of environmental, social, and political issues rather than construction of dams themselves. Huge anti-dam oppositions scrapped them at the cost of nearly ten years for decision-makings and enormous financial resources for feasibility studies respectively. It identifies who the policy actors were, what the policy strategies were, and how the water policies evolved in both countries. The decision-makings on the two projects appeared at first glance to be made under formal institutional frameworks, but in actuality, they relied significantly on decisions of the two important political actors. The Korean society began to learn negotiation and cooperation approaches to solve the water conflict by establishing the Joint Task Force Team on Youngwol project in 1999. The team is recognized as a new conflict resolution method in South Korea because a diverse of stakeholder interests voluntarily participated in the decision-making process and discussed water issues directly. Even though the projects resulted in futile fruits in each country, they illustrate the images of the new paradigm that significantly affected in formulating regional water policies in South Korea and the United States.

  • R&D is the core competence of an enterprise. Furthermore, R&D requires huge capital investment and has very risky characteristics. Therefore, to be successful in R&D process, several approaches of engineering economics are used prior to decision-making. Until now, typical approaches of engineering economics such as NPV(net present value) or DCF(Discounted cash flow) have been used. But, they cannot properly capture managerial flexibility to adapt and revise later decisions in response to unexpected market development. In a constantly changing and always uncertain marketplace, managerial operation flexibility and strategic adaptability have become vital in order to successfully capitalize on favorable future investment opportunities and limit losses from adverse market development. For the alternatives of conventional static decision-making approaches, new concept of using real options is introduced. Real option theory is based on financial option's characteristics and checks every revision interval whether situation have changed favorable to decision maker or not. In advantageous situation, the decision maker has only to go on. In contrast, with unfavorable situation, he abandons the investment immediately. In this aspect, real option model is more suitable in very uncertain and dynamic business environment in that it can provide the opportunity to cope with flexibility. This paper suggests efficient and effective R&D investment strategy by using real options model. In addition, this paper compares financial options and real options.

  • This study is designed to grope for logical methods in the decision-making process of human beings such as creation and analysis. With this in mind, the paper worked with a process where the designers of a design team gather and analyze their opinions in a design process to decide on the HVAC system of buildings. The paper introduced the fuzzy theory, or one of the methods to quantitatively describe language values with ambiguous features, suggesting a method to determine the judgement and suggestion values of the HVAC designers with the characteristics of language variables as the values of design factors greatly influencing the HVAC system. As a result, the paper tested the possibility of the fuzzy system as a logical method to gather the judgement of HVAC designers in a stage of HVAC type selection exerting a great influence on the experience and judgement of the designers and having powerful linguistic features and to determine an appropriate HVAC type which can satisfy the suggested values of related design factors.

  • Objectives: Balancing benefits and risks through the drug life cycle has been discussed for many decades. The objective of this study was to review the processes and tools currently proposed for benefit-risk assessment of medicinal drugs. It aimed to establish scientific and efficient drug safety management system based on the synthetic analysis of benefit-risk evidence. Methods: We conducted a review of exiting literatures published by regulatory agencies or initiatives. Not only quantitative methodologies but also qualitative method were compared to understand their key characteristics for the benefit and risk assessment of drugs. Results: Recently, benefit-risk assessments have more structured approaches to decision making as part of regulatory science. Regulatory agencies such as European Medicines Agency, FDA have prepared plans to apply benefit-risk assessment to regulatory decision making. Also many initiatives such as IMI (Innovative Medicine Initiative) have conducted research and published reports about benefit-risk assessment. For benefit-risk assessment, four kinds of methods are necessary. Frameworks such as BRAT (Benefit Risk Action Team) framework, PrOACT-URL provide guidance for the whole process of decision-making. Metrics are measurements of risk benefit. The estimation techniques are methods to synthesis and combine evidences from various sources. The utility survey techniques are necessary to explicit preferences of various outcome from stakeholders. Conclusion: There is the lack of widely accepted, validated model for benefit-risk assessment. Nor there is an agreement among academia, industry, and government on methods for the quantitative valuation. It is also limited by available evidence and underlying assumptions. Nevertheless, benefit-risk assessment is fundamental to improve transparency, consistency and predictability for decision making through the structured systematic approaches.
