Narrow-mouth frog (Kaloula borealis) is the only amphibian species of genus Kaloula living in South Korea. They are designated and managed as endangered class II wildlife by the Ministry of Environment, Korea. Therefore, there is a desperate need of a habitat restoration study to prevent the extinction of narrow-mouth frog. This study is primarily for the purpose of presenting the direction and practical applications to restore damaged narrow-mouth frog habitats or to suggest alternative habitat options. The habitat suitability index (HSI) of narrow-mouth frog was applied to the research area in Mokpo City of Jeollanam-do Province, in order to present a new narrow-mouth frog habitat. We analyzed the research area based on historical contexts, ecological environment, ecology, and habitat requirements. The research area was divided into the core, buffer, and transition zones according to UNESCO MAB (Man and Biosphere) to establish local land-use plans. As for the foundation of the plan, we divided the habitat composition of the core, where narrow-mouth frog live in, into wetland (spawning area), grassland (shelter and feeding grounds), and forestland (feeding ground). We had a comparative analysis of habitat suitability in pre and post planning of narrow-mouth frog habitat restoration. For the validation study of habitat restoration plans, the future research should be on the composition of test-bed, continuous monitoring, and scientific habitat maintenance.

Abandoned roads, abandoned expressways included, cause a lot of problems such as contamination and environmental damages to underground water, fragmentation of wildlife habitats yet they are not appropriately maintained or managed because of jurisdictional conflicts and, often more importantly, insufficient budget of governments. The restoration of abandoned roads is known to benefit society and its constituents by providing better environment and higher living standards but the monetary value of the benefit is hard to measure because of non-marketability of the good that the restoration brings about. In this case, the contingent valuation method(CVM) is most powerful in evaluating non-marketable value of goods and hence it is used widely. We also used the CVM to value the benefit of restoration of abandoned expressways to find out: about 40% of total households are willing to contribute positive amount for restoration; better awareness of environmental issues leads to higher willingness-to-pay.

This study aims to present reference data necessary for developing evaluation indicators to analyze the actual resilience of purchased land by investigating the factors that affect the restoration of the purchased land in the riparian zone and quantitatively calculating its importance. The main results are as follows. Firstly, this study identified 34 potential resilience factors through a literature review encompassing domestic and overseas studies and derived seven ecological responsiveness factors, six physical responsiveness factors, and four managerial responsiveness factors through the Delphi survey. Secondly, reliability analysis and Analytic Hierarchy Process (AHP) analysis derived the following important factors: structural stability of the vegetation restored in the purchased land, species diversity of wildlife, structural stability of wildlife, the size of restored wetland after purchase, number of plant species, and the land cover status adjacent to the purchased land. The study results are expected to be helpful information for ecological restoration and management plans reflecting reinforcing factors for resilience at each stage of land purchase, restoration, and management.

서울시는 복개천이었던 청계천을 복원하여 도심지를 통과하는 하천을 만들기 위해 청계천 복원 공사를 수행하고 있다. 청계천 복원 공사 구간을 포함하는 유역에는 서울시 지하철 1, 2, 4, 5, 6호선 등이 통과하고 있으며, 도시 내 비수시설, 하수관거시설 등 자연적인 수문현상에 영향을 주는 인위적인 요소들이 복합적으로 존재하고 있다. 때문에 청계천 복원 공사 후 유역내의 여러 요인들과 공사의 정도에 따라 누수가 발생할 것으로 예상된다. 공사 후 청계천에서의 누수율에 대한 측정은 공사의 성공여부를 결정하고, 향후 지속적인 누수가 예상되는 청계천의 유지 보수에 있어서 매우 중요하다. 특히 청계천의 손실량의 대부분을 차지할 지하로의 누수에 대한 측정은 매우 중요하다. 따라서 누수율을 측정하고, 누수율과 주변 요인들과의 관계를 추정할 수 있는 수문모델링을 수행할 필요성이 있다. 수문모델링은 일회성으로 끝나는 것이 아니라 지속적으로 수행될 필요가 있는데, 그러기 위해서는 청계천 유역에서의 지속적인 수문관련 인문 자연자료를 획득하여 정리할 필요성이 있다. 본 연구에서는 청계천 복원 공사 구간의 유역에 대한 인문 자연자료를 GIS(지리정보시스템)을 이용하여 수치도면과 속성테이블 형태로 데이터베이스화한다. 그럼으로써 청계천 주변 유역에 대한 도시형 수문 모델링 연구에 활용하고, 아울러 공사 후 지속적으로 누수율을 측정하는데 자료를 원활히 제공하여 청계천의 유지 보수에 도움을 줄 수 있는 체계를 마련하였다.

도시에서 하천의 모습은 시대와 함께 변화하여 왔다. 치수의 대상이 되어 제방이 높아 졌고 사람들의 생활에서 조금씩 떨어져 나왔다. 고 밀도화가 진행되는 도시지역에서 치수사업으로 하천정비를 하면서 하도의 직강화 및 콘크리트라이닝이 일반적이 되었고, 하천을 복개하여 주차장이나 도로로 이용하게 되어 도시 생태계를 단절하고 도시인들의 정서를 황폐하게 만들었다. 이에 본 연구는 부산의 23개의 복개하천 중 주요 복개하천 20개소를 선정하여 복개하천의 관리 실태조사 및 복원가능성을 평가하였다. 평가방법으로는 해당하천을 총괄지수, 제방지수, 생태지수, 하천지수로 나누어 평가함으로써 부산시내 하천평가 및 복원가능성을 제시하였다. 연구순서로는 부산시 하천을 크게 4개의 권역으로 나누고 각 하천에 대한 문헌조사, 현장조사 후 하천평가(도시하천의 하천평가기법 개발 및 적용, 2007 윤세의)를 실시하였다. 평가 결과 도시화가 많이 진행된 유역을 가진 하천 일수록 모든 지수들이 낮게 나와 하천총괄지수와 도시화의 진행정도는 밀접한 관계가 있음을 알 수 있었다. 본 연구는 도심복개하천의 기초자료로서의 활용, 복개하천의 이용실태를 파악하고 개선방안을 제시해 기초 자료로서의 활용에 목적이 있다.

The weapon system based on voice call can cause delay, error or damage to the message during the exchange of information. Furthermore, since the weapon system has a unique message format, it has limited data distribution. Therefore, a Korea Variable Message Format(KVMF) has been developed in this study to utilize a standard sized data format to guarantee the transmission quality and minimize the transmission amount. The ground tactical data link system quickly and accurately shares tactical information by incorporating a field management system that utilizes the KVMF standard message in the mobile weapon system. In this study, we examine the possibility of performing the mission immediately by recovering the state of network joining when a normal/abnormal termination situation of the battlefield management system occurs.

Purpose: The purpose of this study was to identify the predictors influencing on resilience in adolescents with cancer. Methods: The participants consisted of 107 parents and 107 adolescents who aged ten and eighteen diagnosed with cancer more than six months and currently receiving outpatient treatment or further management after off-therapy. Data was collected using self-report questionnaires and analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation, and multiple regression. Results: Resilience was significantly different by religion (t=2.472, p=.045) and number of cancer treatment regimens (F=3.155, p=.047). Family problem-solving communication was also significant by number of cancer treatment regimens (F=3.582, p=.031). The higher social support showed the stronger family hardiness and the better family problem-solving communication. In addition, a positive relationship was found between Family Hardiness Index (FHI) (r=.193, p=.046), Family Problem Solving Communication (FPSC) (r=.226, p=.019) and resilience of adolescents with cancer. FPSC (${\beta}$=.356, p=.045) and religion (${\beta}$=.441, p=.002) were predictive factors at ages 10-12, FHI (${\beta}$=.509, p=.029) and FPSC (${\beta}$=.503, p=.037) were predictive factors at ages 13-15 on resilience of adolescents with cancer that explained 16.0% and 24.3% respectively. Conclusion: The findings suggest that nursing interventions should focus on enhancing family resilience and resilience of adolescents with cancer.

Ecological restoration is an ecological technology that diagnoses problematic ecological spaces and restores the damaged ecosystem to a healthy appearance similar to its original appearance based on reference information obtained by analyzing intact nature. To achieve successful restoration, the project must be carried out in respect of a series of procedures. However, in Korea, restoration projects are usually actively promoted regardless of diagnostic evaluation, which wastes cost and energy, and the effect is not significant. As the reference information is not utilized, ecological restoration to return the damaged nature makes features different greatly from the appearance of nature, causing another damage. As the restoration effect is not evaluated, it is impossible to determine whether it is successful or not, and as a result, even if the project continues, there is no development and no effect. However, advanced societies have not only made academic progress by respecting these procedures but also have great economic effects along with the improvement of environmental conditions as ecological restoration has become an industry. Therefore, the international society recognizes ecological restoration as an important means of solving environmental problems at the global level, including climate change, and international organizations are actively promoting projects to treat the injured planet. However, most of the restoration projects promoted in Korea were evaluated below the level as a result of the evaluation of the effect. Nevertheless, those who have led low-quality projects are blocking plans to establish ecological restoration as a new industry that can contribute significantly to improving these levels, and thus the problem is expected to worsen. To solve this problem, it is necessary to filter out defective businesses by introducing a strict and correct project evaluation system by dividing it into before and after. Furthermore, it is necessary to establish ecological restoration as an industry and leave the process in the principles of the market.
