  • While a concept on biotop or the urgency of its classification systems have been under discussion recently, this study aims to examine outdoor biotop classification systems for environment-friendly community. To this end, the feasibility of creating a biotop in the community and application elements were generated and biotops were classified and categorized. Then, elements that can be applied in consideration of traditional Korean techniques were generated and biotop classification systems and specific components in residential areas were reviewed. As for the result of this study, based on a preliminary draft prepared through literature review, considerations for biotop classification systems were taken into account. Then, based on classification criteria for biotop formats, biotop functions and biotop types, a second-tier classification system was developed. Criteria for biotop formats included surfaces, lines and points while criteria for biotop functions were large cores, small bases, corridors, stepping stones and ecological islands. Criteria for habitat types were divided to include natural forest, developed green areas, lacustrine wetland, palustrine wetland, shrubs, grasslands, linear habitats, vacant plots and practical green areas, which were sub-categorized. As for the biotop classification system, macro-classification divided biotops into three types-space, line and point-based on biotop formats. Meso-classification had five groups and micro-classification had 21 groups based on habitat types. Future studies should focus on the ecological features of each biotop categories generated in this study and their creation and management techniques to find many practical methods to create, protect and manage outdoor biotop for environment-friendly community.

  • The objectives of this research is searching for the improvement scheme of spacial use of the Nature Environmental Conservation and its Utilization Facility through the analysis of those existing facilities from the structural and operational view points. In this study, firstly, analysis is commencing with the distinction of lawful and operational concepts of Nature Environmental Conservation and its Utilization Facility. In law, the concept is defined as an individual facility, while practical use of the concept has been understood as a collective space itself. Secondly, frequency tables in regard to the duration of the construction, types of location and objectives, and facility numbers are prepared on the basis of 53 cases of completed and under construction facilities. Conclusively, through the comparisons of facilities of Korea, United Kingdom and Germany, the future considerations on the improvement of the facilities in light of structural and operational aspects has been recommended. In structural view, ecological conservation aspect should be considered from the planning stage of the facility. And at the operational stage, various considerations should be given to the employment of facility experts and development of educational programs respectively.

  • Nature-based Solutions (NbS) are defined as practical and technical approaches to restoring functioning ecosystems and biodiversity as a means to address socio-environmental challenges and provide human-nature co-benefits. This study reviews NbS-related literature to identify its key characteristics, techniques, and challenges for its application in climate-adaptive water management. The review finds that NbS has been commonly used as an umbrella term incorporating a wide range of existing ecosystem-based approaches such as low-impact development (LID), best management practices (BMP), forest landscape restoration (FLR), and blue-green infrastructure (BGI), rather than being a uniquely-situated practice. Its technical form and operation can vary significantly depending on the spatial scale (small versus large), objective (mitigation, adaptation, naturalization), and problem (water supply, quality, flooding). Commonly cited techniques include green spaces, permeable surfaces, wetlands, infiltration ponds, and riparian buffers in urban sites, while afforestation, floodplain restoration, and reed beds appear common in non- and less-urban settings. There is a greater lack of operational clarity for large-scale NbS than for small-scale NbS in urban areas. NbS can be a powerful tool that enables an integrated and coordinated action embracing not only water management, but also microclimate moderation, ecosystem conservation, and emissions reduction. This study points out the importance of developing decision-making guidelines that can inform practitioners of the selection, operation, and evaluation of NbS for specific sites. The absence of this framework is one of the obstacles to mainstreaming NbS for water management. More case studies are needed for empirical assessment of NbS.

  • For biodiversity conservation, the importance of beta-diversity which is changes in the composition of species according to environmental changes has become emphasized. However, given the systematic investigation of species distribution and the accumulation of large amounts of data in the Republic of Korea(ROK), research on the spatialization of beta-diversity using them is insufficient. Accordingly, this research investigated the applicability of the Generalized Dissimilarity Modeling(GDM) to ROK, which can predict and map the similarity of compositional turnover (beta-diversity) based on environmental variables. A brief overview of the statistical description on using GDM was presented, and a model was fitted using the flora distribution data(410,621points) from the National Ecosystem Survey and various environmental spatial data including climate, soil, topography, and land cover. Procedures and appropriated spatial units required to improve the explanatory power of the model were presented. As a result, it was found that geographical distance, temperature annual range, summer temperature, winter precipitation, and soil factors affect the dissimilarity of the vegetation community composition. In addition, as a result of predicting the similarity of vegetation composition across the nation, and classifying them into 20 and 100 zones, the similarity was high mainly in the central inland area, and tends to decrease toward the mountainous areas, southern coastal regions, and island including Jeju island, which means the composition of the vegetation community is unique and beta diversity is high. In addition, it was identified that the number of common species between zones decreased as the geographic distance between zones increased. It classified the spatial distribution of plant community composition in a quantitative and objective way, but additional research and verification are needed for practical application. It is expected that research on community-level biodiversity modeling in the ROK will be conducted more actively based on this study.

  • 레이저 융착된 광섬유의 절단 부위에 대한 보호를 위한 관심이 크게 높아지고 있다 일반적으로 절단된 광섬유의 융착부분은 다른 부위에 비해 상대적으로 매우 취약하며 이러한 이유로 광섬유를 광 통신망에 사용할 때 동일 부분에서의 손실이 추가적으로 일어날 수 있다 일반적으로 광섬유 융착 부위는 일반 광섬유의 파괴 강도에 비해 약 1/10인 0.4~l kg로 감소된다. 이러한 이유로 인해 광 융착 부위의 보강이 절실히 요구되고 있다. 그러나, 이러한 구조물의 대부분이 철심 형태의 구조물을 삽입한 슬리브로 보강됨에 따라 굽힘에 대해 효과적으로 대응하지 못할 뿐 아니라 일단 구조물이 굽혀졌을 경우에는 지속적인 광 손실을 발생시키는 요인이 된다. 이러한 문제점을 보완하기 위하여 복합재료로 제작된 코일형 스프링 구조물 형태의 슬리브가 제안되었다. 이러한 슬리브는 기존의 슬리브의 취약점이었던 직하중에 대해 서로 효과적으로 반응할 뿐 아니라 굽힘 및 인장/압축 하중에도 효과가 있음을 알 수 있었다.

  • In urban space, public space is publicly or privately owned space freely accessible by the public. Privately owned public space to the public hosts small-scale rest facilities to serve the public in buildings of certain purposes and sizes for the sake of pleasant urban environment. The Building Act and building ordinances formulate a set of criteria for management and easement of construction standards as well as the area. When creating privately owned public space, one can get incentives through the easement of floor space index and height limit. The purposes of this study were to investigate and analyze privately owned public open space, which is freely accessible by the public, and its adjacent streets and to propose plans to improve the regulations for securing privately owned public space for more rational and practical legal applications. The study then proposed some plans to help to increase the quality of privately owned public space including applying the coefficient to suggest the type of privately owned public space fit for the features of the streets and measure the appropriate utility level differently and distinguishing the mandatory items according to the facility regulations in privately owned public space from the ones qualified for additional points in case of installation. The types of privately owned public open space should be applied differently and the content of facilities intended should be different according to whether it will serve as a resting place or grant more importance on traffic by walking, depending on the features of its adjacent streets. The privately owned public space, the frontage space of building, and the adjacent sidewalks should become a whole and be regarded as one space from the integrated perspective. The results of the study claim further significance in that it investigated privately owned open space and roadside across Seoul. They will serve as useful data to solve the problems with the privately owned public space of the city, which destroys spatial continuity by focusing on the quantitative increase of privately owned open space and creating individual privately owned open spaces and builds high-rise buildings alienated from the existing spaces, and to increase the quality of future privately owned public space.

  • 본 연구는 스파의 서비스 실패로 인해서 발생한 고객의 불만을 고객만족으로 전환시키기 위한 가장 유용한 회복전략이 무엇인가를 각각의 공정성 요인을 통해 살펴보고 고객 불만 대처시스템을 구축하여 스파 고객의 불만이나 불평을 해결하기 위한 실질적인 대응 방안으로 제시하고자 하였고, 서비스 실패에 대한 회복 후 사후행동으로서 대안매력, 전환의사와의 관계를 검증하였다. 그리고 이 과정에서 서비스 실패 회복에 따른 신뢰 형성이 어떠한 매개효과를 지니는지를 분석하였다. 본 연구의 목적을 달성하기 위해, 최근 1년 이내 서울 및 경기도 지역에 위치한 미용에스테틱 목적의 사설 데이 스파(Day Spa) 이용고객으로서, 성인 여성을 대상으로 하였다. 이들을 대상으로 스파 서비스에 불만과 불평을 한 경험이 있는지 파악한 후 이들이 지각한 스파 업체측의 회복 노력에 대해 공정성과 신뢰의 지각과 사후 행동으로서 대안매력과 전환의사를 조사하였다. 연구 가설의 검증결과, 스파 서비스 품질에 따른 서비스 회복 노력의 공정성 요인인 분배공정성 절차 공정성 상호작용 공정성의 세차원에 대해 긍정적 일수록 회복 만족이 증가하는 것으로 나타났다. 회복만족과 신뢰, 대안매력, 전환의사의 관계에서 회복 만족은 신뢰에 긍정적인 영향을 미치고 대안매력에는 부정적인 영향을 미친다는 결과가 나왔으나, 당초 회복 만족이 전환의사에 부정적인 영향을 미칠 것이 라는 가설과는 달리 긍정적 유의미한 결과가 나타났다. 또한 회복만족이 전환의사에 미치는 직접효과 보다는 신뢰나 대안매력을 매개한 간접효과를 고려해야 하는 것을 의미한다. 본 연구에서 회복 노력과 전환의사 간에는 간접효과가 높고 총 효과가 긍정적인 결과를 나타내는 것으로 보아 회복 만족이 감소하면 전환의사가 높아 진다기 보다는 신뢰나 대안매력의 동반증가가 전환의사 를 높이는 것으로 해석 할 수 있다. 전환의사와 신뢰, 대안매력의 관계에서 신뢰와 대안매력은 전환의사에 각각 부정적인 영향과 긍정적인 영향을 주었고, 또한 신뢰는 대안매력 에도 부정적인 영향을 주었다. 고품질의 서비스 또는 서비스 회복이 고객들의 행위 의도에 확신을 주는 일련의 직접적인 인과 관계가 존재한다는 것이다.
