The open bite malocclusion is a common clinical entity and has multifactorial causes. Development of effective treatment plan and management is dependent on proper diagnosis. The skeletal open bite patient requires a coordinated orthodontic and orthognathic surgical approach to achieve stable occlusion, acceptable esthetics, and improved function. But in case of open bite with severely decayed dentition, restoration in the entire dentition is necessary. Using the facial analysis and diagnostic wax-up, the most effective treatment was prosthetic rehabilitation. The provisional restorations were fabricated to satisfy esthetic and functional requirements, which result in the uniformly distributed occlusal force, anterior and canine guidance. The inter-arch relationship, labio-dental harmony, and the soft tissue aspect, which is important to estimate the longevity were evaluated. Definitive restorations of monolithic zirconia were made by replicating provisional restorations by using the latest CAD/CAM technology. They were delivered to the patient and clinical follow-up observation was satisfactory.

This case is a porcelain laminate veneer (PLV) and all-ceramic crown treatment case on a female patient in her thirties who visited for esthetic improvement. The patient's chief complaint was protrusive and uneven anterior teeth, and she wanted minimum tooth reduction. The patient was in skeletal class II deep bite. Considering this, check bite method was used for mounting on articulator during diagnostic wax-up. Tooth reduction was done using mock-up base on diagnostic wax-up, and the amount of deletion was checked by index. For the accordance of shade, PLVs were restored in prior to all ceramic crown. After using all-ceramic crown, satisfactory esthetic improvement was obtained.

In esthetic treatments, it is important to consider the arrangement of teeth and the relation between the teeth and soft tissues. A precise diagnosis and establishing an appropriate treatment plan is essential in an esthetic treatment of anterior maxillary teeth. For a fixed prosthesis to meet esthetic expectations, It is crucial to achieve symmetry and adequate proportions of the gingival contour around the crowns. To achieve an esthetic improvement and creating a favorable environment for gingival healing of a physiologic gingival contour, gingivectomy, crown lengthening and forced eruption can be applied to the appropriate site. All ceramics or porcelain laminate veneer can be selected for esthetic improvement of teeth contour and shade. In this case report, malposition of the remaining teeth made it hard to get an esthetic appearance. Gingivectomy, crown lengthening and provisional restoration insertion were performed before the final prosthesis fabrication to reform the gingival form. This case presents satisfying result esthetically and functionally.

국내에서는 과거부터 현재까지 하천을 이수, 치수, 하천환경 등 기능별로 구분하여 관리해 오고 있다. 하지만 하천을 보다 합리적으로 관리하기 위해서는 종합적인 관점에서 접근이 필요하며 하천의 현 상황을 제대로 파악하는 것이 무엇보다 중요하다. 하천을 평가하기 위해 제방축조율, 수질 등 다양한 하천지표 및 평가기법들이 개발되어 왔으나 치수 이수 환경 친수 등 하천의 다양한 기능 중 특정 기능들에 대해서만 단편적으로 진단해 오고 있는 실정이다. 또한 4대강 사업, 생태하천조성 등 다양한 하천사업이 시행되고 있어 그 성과와 필요성을 정량적으로 평가 관리할 수 있는 제도 마련이 필요하며, 하천 기능을 종합적으로 진단하고 이를 객관적으로 정량화할 수 있는 체계 구축이 매우 절실하다고 할 수 있다. 따라서 건전한 하천종합관리체계 구축을 위해 하천의 기능인 이수, 치수, 하천환경 및 친수 요소간의 조화와 평가가 가능한 정량적 지표 및 지수의 개발이 필요하다. 보다 건전한 하천관리체계 구축을 위한 국가 수자원 정책 결정 시 정책결정자가 보다 다양한 정보를 획득하고 이를 통한 분석정보를 바탕으로 여러 가지 대안을 도출할 수 있어야 하며 이는 여러 가지 정보를 종합한 지표를 통해 보다 쉽게 얻을 수 있다. 하천의 다양한 기능에 대한 정보를 종합하여 지표화함으로써 정책결정자는 여러 가지 경우를 고려한 다양한 대안을 검토할 수 있게 되어 최적의 대안 도출이 가능해진다(건설교통부, 2006). 본 연구에서는 한정된 수자원을 다양한 목적과 제약조건을 충족시키면서 효율적으로 이용, 보전하기 위해 하천의 다양한 정보의 연계, 공유를 통한 통합관리체계 구축을 하고자 하천 특성을 표현할 수 있는 다수의 대리변수를 조사, 분석하였다. 또한 조사된 대리변수들 중 하천의 각 기능에 미치는 영향을 충분히 고려하여 대리변수를 선정하고 이를 통해 잠재지표를 선정하였다. 선정된 잠재지표를 이용하여 하천의 각 기능을 평가할 수 있는 하천종합관리지표를 개발하여 국내 국가하천에 적용함으로써 하천 특성의 시공간적인 변화를 분석하였다. 개발된 지표를 통해 국내 하천관련 사업에 대한 B&A 분석을 수행하여 사업 성과를 제시하였다. 본 연구에서 개발된 지표는 하천관련 사업의 전, 후 상황을 분석함으로써 사업효과를 분석할 수 있으며 하천관련 사업의 효과에 대한 대국민 홍보효과를 가져올 수 있을 것으로 사료된다.

The paper is to assess the recent changes in Architectural Artworks system in two regional districts, Seoul and Gyeonggi Province, and to propose policies for further improvement. We focused on four aspects: overall pass rate, top-ranked artists' pass rate, proportion of artists ever passed, genre proportion artworks. It is observed that quality of artworks has improved, market monopolization has been eased, and entry to the market has become more active. However, sculptures accounted for the majority. Public art is gradually changing from 'decorative art' to 'site-specific art', and seeking harmony between architecture and surrounding landscape. To keep pace with this new trend, more institutional efforts should be made: fund raising to induce artwork supplies; introducing life-span concept to secure removal and deformation of artwork; imposing artists' follow-up services; imposing penalties against poor management; and authorizing the committee to choose exhibition sites.

This study reviewed the type of the project and developmental plan related to ocean energy development in the coastal land boundaries and the ocean, and suggested the efficient scoping method through the diagnosis of the key items of environmental impact assessment (EIA) in the coastal area. The major projects are the construction of tidal power plant, tidal current power plant, and offshore wind power plant in the public water, and also those are the construction of solar power plants in the coastal land boundaries. While the project plans on a large scale such as the construction of tidal power plant, it is important to consider both property of usefulness of the designated areas and harmony analysis with marine space availability based on the adequacy of the site selection and relevance of plan with the master plan for reclamation and strategic environmental assessment (SEA). And also it needs to be considered the careful checkup on the EIA checklist referring to the type of project, effective post-monitoring, and suggestion of mitigating methods to minimize the environmental impacts during the stage of actual environmental impact assessment. Introduction of a system of integrated marine environmental impact assessment should be considered for reasonable and effective manage to developmental projects on the marine spatial area.

The treatment of areas demanding esthetic requirements, such as maxillary anterior teeth, should take into account the achievement of a healthy, harmonious to the surrounding tissue, and an attractive smile line. In this case report, smile line, soft tissue and hard tissue morphology, and the anatomy and proportion of the tooth, must be considered. In patients with unesthetic maxillary anterior ratio due to inadequate gingival contour and diastema caused by peg lateralis, it would be challenging to achieve an esthetic restoration by orthodontic treatment alone. In such case, after orthodontic treatment, dento-gingivo-facial compositional diagnosis and analysis, followed by gingivectomy and prosthodontic restoration is needed to improve the interdental mesial/distal, width/length ratio to achieve a satisfactory esthetic result. In addition, when improving the tooth proportion of peg lateralis by prosthodontic treatment, Porcelain laminate veneer (PLV), which results in less tooth structure loss, reproduction of similar shade to that of the proximal tooth and high transparency, is recommended. This case report demonstrates esthetic improvements by prosthodontic restoration through systematic diagnosis and treatment procedure in patients with unesthetic maxillary anterior proportion after orthodontic treatment due to peg lateralis by means of two female patients aged twenty years old.

Bovine incisor was investigated using active infrared thermography(IRT) to visualize crack on bovine teeth. An artificial crack was carefully created in bovine incisor sample by compression load of universal tensile machine. While applying a sinusoidal heat wave to the cracked bovine incisor through halogen lamp, consecutive digital infrared images was captured from the sample surface at a frequency synchronized with heat excitation. Phase information of thermal image was calculated by four-point correlation method and processed to produce the phase image of bovine incisor. This phase image showed clearly the crack on the incisor, which was hardly detected in traditional passive thermography.
