Overdenture is one of the methods of patients with severely worn dentition. Remaining natural teeth help preserve alveolar bone and proprioception and provide rigid support. Also, overdenture distributes the concentrated stress applied to the abutment tooth and denture supporting tissues. There is an advantage that it can provide long-term stability to denture. In this case, the patient with only a few teeth due to severe wear and caries was satisfied with good function and favorable esthetics by using overdenture.

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.

2023년 우리나라에 발생한 재난은 남부지방의 가뭄, 태풍 카눈에 의한 폭우, 7월~9월 폭염 등의 자연재난과 4월 5일 분당 정자교 붕괴, 4월 29일 검단신도시 붕괴사고, 7월 13일 대구 염색산업단지 황산 누출 등의 사회재난이 발생하였다. 이전 2022년에는 022년 10월 29일, 서울 이태원역 부근에 대규모 인파가 한번에 몰리며 압사사고가 발생하여 159명이 목숨을 잃고 196명의 부상자가 발생하였다. 이처럼 다양한 형태로 발생하는 재난에 대하여 우리나라는 「헌법」과 「재난 및 안전관리 기본법」에서 재난으로부터 국민의 생명·신체 및 재산과 국가의 피해를 줄이기 위해 노력하여야 한다고 명시하고 있다. 재난은 다양한 특성을 지니고 있으며, 학자들의 일반적 견해는 누적성, 불확실성, 복잡성, 인지성 등의 특성을 들고 있다(재난관리론, 2020). 특히, 사회재난은 발생위치, 시점, 피해, 규모를 예측하기가 상대적으로 매우 어렵기에(장대원 외, 2019) 불확실성의 특성을 강하게 보여주고 있다. 이러한 사회재난의 특성은 자연재난과 비교하여 사람들에게 물리적·심리적 영향을 크게 미칠 뿐만 아니라 단기간에 회복하기 어려운 특성을 지닌다(신재헌 외, 2020). 이에 대하여 많은 국민들은 심각한 사회재난이 발생할 때마다 정부차원의 적극적 재난관리 및 통제능력 향상을 요구하고 있으나, 사회재난 특성 상 특정 기관 중심으로 대응하기에는 많은 어려움이 있다(신재헌 외, 2020). 우리나라 경찰은 2021년 7월부터 자치경찰제도를 실시하며 국민의 생명·신체 및 재산의 보호, 범죄예방, 수사 및 질서유지업무 이외에 국민들의 봉사·서비스 행정 요구의 증대로 인한 적극적·능동적 경찰활동으로 변화하게 되었다(조호대, 2014). 이에 따라 경찰은 경찰의 재난관리체계를 확립하고, 경찰의 재난관리에 관한 사항을 규정함을 목적으로 2012년 「경찰 재난관리규칙」을 제정하였다. 이에 본 연구에서는 경찰의 재난 발생 시 역할이 무엇이며, 특히 사회재난 시 경찰의 적극적 대응 방안은 무엇인가에 대하여 살펴보고자 한다.

In edentulous patient, not only mastication and pronunciation but also esthetics are compromised. By restoring an edentulous patient with complete dentures, masticatory function and esthetics can be rehabilitated. The advantages of the dentures using CAD/CAM are that they can be reconstructed ubiquitously with stored data, and the strength and density of CAD/CAM material are clinically acceptable. In this clinical report, interocclusal record was taken in a conventional manner and then two lab processing procedures were performed: conventional method and CAD/CAM method. Two types of processing procedures were compared and evaluated. Fair clinical results were obtained in both ways, satisfying the patient.

Korean churches and theology of today are experiencing a decline in reliability and a lack of communication from the Korean society due to the absence of proper reflection. Moreover, with the COVID-19 Pandemic, the church is led to a situation where the problem of survival has become a concern. In addition, churches and theology failed to restore the public nature of faith from civil society, and how these beliefs could be developed in terms of Christian education has become an important theological task. The restoration of the public nature of the church brings interest in public theology, and if education is an important area of the public forum, we pay attention to educational philosophers who provided the basis for publicness and civil democracy education philosophy in Christian education. Rousseau, as an educationalist who opened the modern philosophy of education is opening up the civil society through discovering the existence of children with the proposition "Return to Nature" in the 18th century. This study aims to use Rousseau's educational philosophy in his books Emil, The Theory of Inequality Origins, and Social Contract Theory as the basis of educational theory that opened the foundation of the public domain and civil society.

Physiologic tooth attrition is accepted as a natural change. But when pathologic changes, such as loss of occlusal vertical dimension, masticatory pain, loss of masticatory function, and loss of esthetics occur, restorative measures should be taken by dentist. A patient visited the clinic with the chief complaint of 'My lower teeth bite the palate and it hurts'. It was diagnosed as iatrogenic attrition of lower natural dentition caused by inappropriate upper restorations, resulting in traumatic overbite. Through model analysis and diagnostic wax up, increase in vertical dimension was decided. Upper and lower dentitions were restored with new prostheses. After restoration, satisfactory outcomes were achieved both in functional and esthetic aspects.

Post-fire restoration can affect breeding bird communities and species compositions over a long-term period by determining pot-fire succession, and a long-term monitoring is therefore required to understand its impacts on forest birds. This study aimed to document the effects of post-fire restoration methods on breeding bird communities in three areas: unburned and two burned (nonintervention and intervention with clear-cut logging and planting) stands 13 years after the stand-replacing Samcheok forest fire at Mt. Geombong in Samcheok, South Korea. According to 108 point counts during the breeding season from April to June 2013, we found that the number of individuals, observed bird species, and species diversity index in intervention stands with clear-cut logging and planting were lower than that in nonintervention and unburned control stands. Foraging and nesting guild analysis also showed a lower abundance of foliage searchers, timber drillers, primary cavity nesters and secondary cavity nesters in intervention stands than in the other stands, while no significant difference was detected between the nonintervention and unburned stands. These results imply that an interventional restoration method may deter the recovery of avian breeding communities after forest fires, and also suggest that non-interventional restoration methods may be an effective way to benefit the species diversity and density of breeding bird communities.

It is widely recognized that destruction of the eco-system with the counter-effect from the rapid industrialization threatens the life of human species. Furthermore, the extinction of some wild species keeps sending a warning message on the threat to human lives in the sense that both the human and wild lives have coexisted for a long time before the industrialization. Therefore, this study will shed a light on the importance of a natural ecology protection, focusing on wild-life conservation. This will provide an opportunity to consider the economic value of biodiversity through conservation of diverse wild lives and a natural ecology. Also, the irreversible damage to natural resources and extinction of certain species represent the urgency of this issue. This paper will perform a theoretical examination on the concept of wild plants and animals, an analysis of factors influencing their survivals, as well as the theory of natural ecology protections. This also examine the problems arising out of current domestic legislation of a natural ecology protection, comparing it with case studies of foreign countries. Through these analysis, this paper will seek for a maintenance of the currently enforcing natural ecology protection law to overcome its limits and will ultimately find alternatives to current system.

It's the situation that modern technological civilization shakes the life environment fundamentally without a serious reflection on the dangers. The sense of crisis' brought the rise of modern Ecology in awareness of survivability of the humanity. Because the serious reflection is not just a campaign for environmental protection, but is to establish the values which is possible to coexist and to make harmony between the nature and man, man and man, and to form a healthy relationship through philosophical thought and practice has intrinsic value for human and nature. Under these circumstances, if Yulgok lives now and he is questioned by the ecological theorists of the 21st century that "What do you think about the serious environmental problem of present times?", what really would be his explanation? In the presentation methods of the explanation, will question first what contents western ecologists who study Theory of the environment in technology, Deep Ecology, and Social Ecology propose, then will compare and introduce what similarities and differences from theirs. As a result, we'll be found that Yulgok's thought, moral consciousness, about the nature and humanity as a confucian scholar.

Fixed restoration using implants for patients with posterior partial edentulism is generalized technique. As patient demands increase, the functional and esthetic implant restoration to achieve similar results to lost natural teeth is becoming an important issue. It is inevitable to use customized CAD/CAM abutments rather than ready-made abutments for the creation of implant prosthesis which closely resembles natural teeth. Using CAD/CAM abutment made it possible to obtain natural emergency profiles for posterior implant prostheses, ensuring more comfortable, efficient management of oral hygiene. However, keratinized gingiva with sufficient width and height for a natural emergence profile is required to use a large diameter CAD/CAM abutment which ensures stability and esthetics of hard/soft tissue around the implants. In this case, for esthetical and functional implant zirconia prosthesis, soft tissue graft was performed and customized CAD/CAM abutments were used following ridge augmentation, sinus graft and implantation. Satisfactory results were obtained functionally and esthetically through periodic clinical evaluation, and I hereby report this case.
