Floods are the most common natural disasters and are annually causing severe destructions worldwide. Human activities, along with expected increased extreme precipitation patterns as a result of climate change enhance the future potential of floods. There are proven evidence that infrastructure based responses to flood disaster is no longer achieving optimum mitigation and have created a false sense of security. Nature-based solutions(NBS) is a widely accepted sustainable and efficient approach for disaster risk reduction and involves the protection, restoration, or management of natural and semi-natural ecosystems to tackle the climate and natural crisis. Adoption of NBS in decision-making, especially in developing nations is limited due to a lack of sufficient scenario-based studies, research, and technical knowledge. This study explores the knowledge gap and challenges on NBS adoption with case study of developing nation, specially for flood management, by the study of multiple scenario analysis in the context of climate, land-use change, and policies. Identification and quantification of the strength of natural ecosystems for flood resilience and water management can help to prioritize NBS in policymaking leading to sustainable measures for integrated flood management.

The purpose of the present study was to compare the long-term management objectives, policy objectives, implementation plans, and detailed plans of four provincial parks established in 2013 using various analysis frameworks. Through this, the study aimed to identify the characteristics of the management plan and extract the implementation plan important to each park by analyzing the priorities in the detailed plan. The long-term management objectives of most parks were to maintain recreational functions by utilizing all the resources of the park, rather than merely preserving the ecosystem. From an ecological perspective, information on major plants and legal protection species are included for most parks, and geological and topographic features considered a major resource. For sustainable forests, it is important to induce the dispersion of concentrated use space. Efficient management systems are distinctively differentiated among the parks. For regional revitalization, the management of programs to link provincial parks and their surrounding areas has become most important. From an ecological perspective, priorities differed for the parks according to their ecological characteristics. For sustainable forests, Moaksan Provincial Park prioritized the visitor reservation system related to the overall park, while the other three parks prioritized alleviating the concentrated use of specific areas. From an efficient management perspective, Daedunsan Provincial Park prioritized aspects related to the cableway. Maisan Provincial Park prioritized inducing the linkage between the use of natural and cultural resources, and Seonunsan Provincial Park prioritized establishing an ecological and cultural commentary operating system. For the base-type leisure activity space, Moaksan Provincial Park prioritized the systematic management and operation of the pilgrimage route, Maisan Provincial Park the connection between the Maisan geography and residents' income, and Seonunsan Provincial Park providing a space for ecological education.

The traditional Japanese agricultural landscape, In which a set of varied land-use patches functions as a sustainable ecosystem landscape unit, not only provides the local people tilth a stable food supply, but also offers a variety of habitats to many species of wildlife. Therefore, remaining natural habitats including those in the traditional agricultural landscape should be maintained whenever possible. In addition, restoration work should be implemented in areas where the natural habitat has been destroyed or severely degraded by human activities. This basic approach to the natural environment is a combination of maintenance and restoration. Types of maintenance and restoration can be classified into three categories according to the countermeasures employed: preservation, conservation and protection types of maintenance, and improvement, reconstruction and creation types of restoration. Four steps are proposed for ecological restoration and maintenance of a target area: exploration, diagnosis, prescription and care. In this process, a model for approaching the goal is important. One of the most important models should center on the traditional agricultural landscape involving a sustainable farming ecosystem. It is necessary to protect traditional landscapes and ecosystems from the degrading impact of urbanization and industrialization, as well as to enhance efforts at restoration.

우주공간의 물리적 변화는 지구를 둘러싼 우주전자파에 영향을 주어서 방송, 통신, 위치측정 및 자원탐사 등을 위한 인공위성에 장애를 일으킨다. 이러한 우주전파 재난은 언제, 어느 정도의 규모로 일어날지가 불확실하다는 특성을 갖고 있다. 최근 국제연합을 비롯한 논의의 장에서 전문가들은 지속가능한 우주환경보호의 차원에서 그러한 재난에 대해서 주목하기 시작했다. 특히 국제연합의 우주의 평화적 이용위원회(Committee on the Peaceful Uses of Outer Space, COPUOS)는 모든 국가가 우주기술을 이용할 수 있는 지속가능한 우주환경의 조성에 유해한 영향을 미칠수 있는 재난의 하나로서 우주전파재난에 주목하기 시작하였다. 불확실성을 특징으로 하는 재난에 대해서 각국의 국내법 및 환경관련 국제 규범은 이른바 사전주의 원칙에 기초한 제도를 운용하고 있다. 사전주의 원칙은 현대형 위험관리 이론으로서, 종래의 전통적인 경찰법제에 의해 관리될 수 없는 위험인 과학적으로 불확실하고, 중대하고 회복할 수 없는 손해를 발생시킬 수 있는 위험을 관리하여야 한다는 사전주의(사전배려)의무의 도덕적, 법적 근거로 파악된다. 일련의 보고서와 전문가들의 의견은 1967년 우주조약을 비롯한 각종 우주법 관련 규범에서 그와 같은 불확실한 재난에 대비하기 위해서 원용될 수 있는 우주법차원의 법 원리를 조심스럽게 주장하고 있다. 우주법의 기본 원칙은 우주공간의 자유로운 항행과 전 국가를 위한 이용을 규정하고 있다. 지속가능한 우주환경은 그러한 항행과 이용을 위해 필요한 것이라는 점에서 의의를 갖는다. 따라서 우주환경의 지속가능성을 저해하는 우주전파재난에 대한 법제도는 우주법의 기본 원칙에 기초한다. 아울러 우주전파재난의 불확실성이 고려될 때에, 현 시점에서 강구될수 있는 법제도가 사전주의 원칙이라면, 그 원칙도 우주법의 기본 원칙에 기초한다.

During the Joseon period, the East Sea would be called 'Gyeonghae' due to a large number of whales. In the Republic of Korea, whaling was locally permitted in 1946. However, the number drastically dropped because the hunting of the marine mammal had already been carried out in Russia, the U.S. and Japan since 1800s. Before a moratorium on commercial whaling was introduced by the International Whaling Commission(IWC) in 1986, whale populations in the East Sea had plunged. Furthermore, Korean gray whales and fin whales weren't found anymore in that area. With the suspension, whale hunting was banned in Korea as well. Even so, accidentally caught whales have been allowed to be distributed on the market with respect for local food culture. With the establishment of Whale Museum and hosting of the 57th Annual Meeting of the International Whaling Commission(IWC) at Jangsaengpo in 2005, whale tourism was facilitated in earnest. This whale tourism has been operated by Nam-gu Office and Nam-gu City Management Corporation in Ulsan. However, the popularity of whale tourism has increased a demand for whale meat. At the same time, there has been concern over decrease in whale populations because of illegal whaling. In addition, a conflict between the use and protection of whales has caused confusion in tourism identity. Actually, there is a serious doubt on the sustainability of whale tourism due to the decade-long deficit and excessive investments. This study attempts to define a concept of whale tourism and propose a future direction for the sustainable growth and development of Korea's whale tourism industry after developing such comprehensive assessment indicators as a basic research for the introduction of sustainable whale tourism. To achieve the aim of this study, AHP(Analytic Hierarchy Process) was chosen as a main research tool and the factors were ranked by a comprehensive analysis of principal factors and detail factors. The current study showed the following results. First, ecological environment(0.430) was indicated the most important factor of whale tourism assessment indicators. Moreover, Population(0.1302), Action for Cetacean protection(0.1031), Governance(0.0898) were critical factors. On the other hand, Accommodations(0.0085), Whale meat(0.0088) were unimportant factors than others.

This paper reviews the future directions and perspectives on the soil environmental researches in the 21 century. Previously, the principal emphasis of soil environmental researches had put on the enhancement of food and fiber productions. Beside the basic function of soil, however, the societal needs on soil resources in the 21st century have demands for several environmental and social challenges, occurring regionally or globally. Typical global issues with which soil science should deal include food security with increasing agronomic production to meet the exploding world population growth, adaptation and mitigation of climate change, increase of the carbon sequestration, supply of the biomass and bioenergy, securing the water resource and quality, protection of environmental pollution, enhancing the biodiversity and ecosystem health, and developing the sustainable farming/cropping system that improve the use efficiency of water and agricultural resources. These challenges can be solved through the sustainable crop production intensification (SCPI) or plant welfare concept in which soil plays a key role in solving the abovementioned global issues. Through implementation of either concept, soil science can fulfill the goal of the modern agriculture which is the sustainable production of crops while maintaining or enhancing the ecosystem function, quality and health. Therefore, directions of the future soil environmental researches should lie on valuing soil as an ecosystem services, translating research across both temporal and spatial scales, sharing and using data already available for other purposes, incorporating existing and new technologies from other disciplines, collaborating across discipline, and translating soil research into information for stakeholders and end users. Through the outcomes of these approaches, soil can enhance the productivity from the same confined land, increase profitability, conserve natural resource, reduce the negative impact on environment, enhance human nutrition and health, and enhance natural capital and the flow of ecosystem services. Soil is the central dogma, final frontier and new engine for the era of sustainability development in the $21^{st}$ century and thus soil environmental researches should be carried according to this main theme.

Plants and microorganisms (microbes) use information from chemicals such as volatile compounds to understand their environments. Proficiency in sensing and responding to these infochemicals increases an organism's ecological competence and ability to survive in competitive environments, particularly with regard to plant-pathogen interactions. Plants and microbes acquired the ability to sense and respond to biogenic volatiles during their evolutionary history. However, these signals can only be interpreted by humans through the use of state-of the-art technologies. Newly-developed tools allow microbe-induced plant volatiles to be detected in a rapid, precise, and non-invasive manner to diagnose plant diseases. Beside disease diagnosis, volatile compounds may also be valuable in improving crop productivity in sustainable agriculture. Bacterial volatile compounds (BVCs) have potential for use as a novel plant growth stimulant or as improver of fertilizer efficiency. BVCs can also elicit plant innate immunity against insect pests and microbial pathogens. Research is needed to expand our knowledge of BVCs and to produce BVC-based formulations that can be used practically in the field. Formulation possibilities include encapsulation and sol-gel matrices, which can be used in attract and kill formulations, chemigation, and seed priming. Exploitation of biogenic volatiles will facilitate the development of smart integrated plant management systems for disease control and productivity improvement.

To explore the potential use of Ecklonia cava as a natural dye for textiles, silk fabric was dyed with Ecklonia cava extracted by hot water under varied conditions, including temperature, duration, dye concentration, mordanting, and pH adjustment. The fabric was also evaluated for fastness, sun-protective property, and deodorization. Ecklonia cava extract was estimated by FT-IR to have polyphenol as a main functional colorant in plants, while the existence of phlorotannins through the UV-spectrum method was also confirmed. The fabric was optimized for maximum dye uptake at a temperature of 80℃ for a duration of 50 minutes along all dye concentrations. The dyed fabric showed a hue of Yellow Red under all dyeing conditions while additional color tones, such as grayish and dark, were generated through mordanting and pH adjustment. Both good sun-protective properties and a positive deodorization rate were also recorded, with more than 20% (owf) Ecklonia cava extract on silk fabric. These results imply that Ecklonia cava has great potential to be used as an eco-friendly natural dye and in fashion goods with skin-health functions made of silk.

본 연구는 갯벌의 생태계 및 환경 현황, 갯벌 주변의 사회경제적 이용현황, 지역주민 설문조사 등의 다양한 자료를 활용하여 갯벌을 관리유형별로 구분하였고 이에 대한 기본 관리방안을 도출하는 것을 목적으로 한다. 이를 위해 간의 사회경제활동과 환경과의 관계를 규명하기 위해 채택한 압력-상태-대응 구조(PSR 구조)를 활용하였고, 갯벌 유형을 보호습지대상지역, 습지개선지역, 이용조정지역으로 구분하였다. PSR 평가체계를 활용하여 보호습지대지역은 34개, 습지개선지역은 26개, 이용조정지역은 9개의 단위 갯벌로 나타났다. 갯벌 관리의 기본방향은 갯벌 유형에 따라 지역의 특성을 고려하여 구체적인 방안을 달리하여야 할 것이다. 보호습지대상지역은 습지보호지역 지정시 우선적으로 검토되어야 하며 갯벌목록 및 모니터링을 통해 지속적인 연구와 관리계획 수립이 이루어져야할 것이다. 습지개선지역은 자연상태로 개선이 가능한 곳으로 판단되는 지역이고 이를 위해 압력요인 완화와 복원이 이루어져야 할 것이다. 이용조정지은 보전 및 개선의 필요성이 낮은 지역으로 심각한 위협을 줄 수 있는 이용행위의 조정이 필요한 지역이다. 그러나, 기본적으로 갯벌의 보전과 장기적으로 지속가능한 이용에 우선순위를 두어 관리방안을 마련하는 것이 중요하다.
