Since the implant became the important treatment modality in dentistry, the research and clinical effort to mimic natural tooth appearance have been pursued. While the rehabilitation of mastication and occlusal appearance was focused in the past, more esthetic and functional restoration was preferred recently. To fulfill this demand, the clinicians should consider the axial contour, papilla space, subgingival appearance, as well as the shape of occlusal surface. In the surgery part, there have been significant advances in the adequate formation of bone and soft tissue through the careful reflection on the surgery time and incision. When the dentist has good knowledge about this aspect and passion for the final product, he or she can acquire better results.

The purpose of this study is to build user's psychological response process model on design evaluation. Users firstly evaluate design factors such as form, structure, texture and colors which are basic elements of product design. These factors, however are affected by product's situational factors, user's individual factors and environmental factors. That is, even same design can be evaluated differently by users according to product's situational factors such as price level, brand prestige level and marketing programs, and user's individual factors such as tastes, involvement level, personality, lifestyles and demographics, and environmental factors such as culture, sub-culture, social class, reference group and family and so on. Understanding how users evaluate product design is necessary to increase the possibility to create user-preferring design and also is the starting point of user-based design and design marketing. In the future researches, it is necessary to examine more factors which are not included in the study and to find out the relationship between factors affecting user's evaluation on design and user's psychological response.

본 연구는 갤럭시 폰을 선호하는 사용자의 감성경험디자인 요소의 주관적 관점을 밝히는데 초점을 두었으며 주관성 연구를 위해 Q 방법론을 통해 3개의 유형을 발견할 수 있었다. 제 1 유형은 합리적 행동 추구 유형으로 갤럭시 폰에 대한 직 간접 체험을 통해 감성품질에 대한 높은 기대치를 가지고 있으며 휴대성과 사용성을 중요시 하고 외형의 형태와 재질에 관해서는 낮은 선호도를 가지고 있음을 알 수 있었다. 제 2 유형은 계획된 행동 추구 유형으로 주관적인 개인의 지각을 중요시하며 기능, 물리적 느낌 그리고 사용성 모두를 중요하게 생각하고 사용함으로써 얻어지는 즐거움과 효율을 선호하는 유형으로 구분되었다. 제 3 유형은 차별적 개성 추구 유형으로 개인이 소유한 제품을 통해 다른 이에게 전달하고자 하는 메시지를 중요하게 여기며 심미적 요소의 차별을 통한 개성 표출을 중요시하는 유형으로 파악되었다.

When restoring their anterior dentition, patients become more demanding on esthetics compared to posterior region during treatment planning phase. Digital Smile Design (DSD) procedure is performed in presentation software and digital photographs. This can widen diagnostic visualization and aid in transferring information between clinician, patient, and technician. This case presented is that of patient with dissatisfaction of his anterior old restoration. Retreatment procedures were carried out in two different manners: (1) using DSD protocol for diagnosis, smile simulation, communication and fabricating interim and definitive prosthesis by totally digitized workflow. (2) Using diagnostic wax-up for smile design and fabricating restorations by conventional workflow. Comparing two methods, DSD was easier to communicate between the dental team than the diagnostic wax-up method. But the final result obtained failed to meet total esthetic factors. Therefore, to obtain predictable esthetic results, more advanced design tool would be needed, including consideration of various esthetic factors besides successful communications.

There have been a great number of developments in clinical techniques and dental materials in dentistry to date. Looking at these developments, while it could be seen that functional elements such as mastication were prioritized rather than aesthetic aspect in the past, aesthetic needs of patients have steadily increased over time and accordingly the aesthetic has become considered a priority in the development of dentistry. Although the first to be considered in discussing the aesthetic in clinical dentistry will be the white aesthetic that is the tooth part of prosthesis, the pink aesthetic that refers to the harmony of such prosthesis with gingiva can be an important consideration not to be ignored aesthetically. However, the harmony with the gingiva often cannot be obtained only by the beautiful prosthesis, and in particular, the pontic and implant areas have poor conditions to achieve the gingival (pink) aesthetic due to the absorption of alveolar ridge compared to natural teeth. Among the most important elements of the gingival aesthetic are the gingival level and the interproximal papilla height. It is very difficult to make the gingival aesthetic in the case of insufficient alveolar ridge, and the recovery of ridge volume and contour is necessary in order to overcome this condition. To this end, the most widely used method is the "connective tissue graft". Many techniques of the connective tissue graft have already been introduced for the ridge augmentation, and each technique has different purposes, and advantages and disadvantages. Rather, due to the excessive amount of techniques, there is confusion about selecting the right technique at a certain time. However, the goal is clear. Ways to increase the success rates must be found, and at the same time, a more favorable way to the gingival aesthetic is to be chosen. Thus, in this study, considerations for the gingival aesthetic that makes harmony and the techniques to achieve it are discussed.

본 논문은 두개의 날개를 가진 다양한 생명체들의 형상과 움직임을 복잡한 공기역학 없이 body-brain 공진화를 사용하여 생성하는 시스템을 기술한다. 인공생명 기술이 다양한 가상생명체들을 생성하는데 이용되었지만 제한된 기하학적 요소들을 사용한 날개 생성의 어려움과 매우 복잡한 공기역학으로 인하여 하늘의 생명체들을 탐색한 연구들은 매우 드물다. 본 논문의 진화된 생명체들은 시스템의 단순함에도 불구하고 심미적인 모습과 유기적인 날개침 동작을 보여준다. 진화 알고리즘을 위한 유전형 인코딩에 쓰인 자료구조는 제한된 리스트 구조로서 이는 방향그래프와 유사하나 더욱 쉽게 다루어질 수 있다. 본 시스템으로 진화된 생명체는 연속적인 삼각형 패치로 이루어진 두개의 대칭형 날개를 가지며, 새, 나비, 박쥐 혹은 상상적인 용이나 익룡 등을 연상시키는 다양한 모습과 기동을 보여준다.

As the increased certainty of osseointegration, new parameters are now being used to assess implant success. Accordingly, patients' and clinicians' high demands and expectation for esthetics have expanded and implant-supported restorations show better esthetic outcomes. The pre-implant treatment planning process, the implant surgical steps and the post-surgery prosthetic process can affect all esthetic outcomes. Prevention of esthetic implant failures can be achieved by appropriate treatment at each stage, considering the 3 factors of alveolar bone, soft tissue, and implants. It is necessary to achieve the esthetic implant prostheses followings: minimal invasive surgery, bone augmentation, ideal 3-dimensional implant position, peri-implant soft tissue management, and provisional restorations to optimize peri-implant soft tissue architecture.

There has been no enough consistency about the question of 'Is it possible for golden section to be applied to product design\ulcorner'In addition, There has been no near answer about 'What is proportion\ulcorner and 'How can proportion be approached\ulcorner About this matter, this study identified various types of proportion through experiment design and consumer surrey. According to the results of this study, various and different types of proportion exist in product design and therefore, proportion in product design couldn't be considered by one-dimensional aesthetic element. This kind of study about the types of proportion could give an good answer abort the matter of 'Is it possible for golden section to be applied to product design\ulcorner'and it's expected practically to give a useful insight to the approach of Product design in Which proportion is considered. In addition, preferred proportion structure is different according to the consumer characteristic, successful design strategy such as niche market penetration could be performed if designers classify consumer characteristic systematically.
