Tooth avulsion usually causes inflammatory root resorption and ankylosis, and ankylosis cause severe functional and esthetic problems, especially in childhood. A 7-year-old female visited the Dept. of Pediatric Dentistry, Yonsei University with the chief complaint of avulsive trauma to the upper right incisor which was left dry for 40 minutes. Tooth was irrigated with saline and replanted immediately and splinted. Anti bacterial agent and anti inflammatory agent were prescribed. After 4 months of replantation slight external root resorption and apical radiolucency was seen at radiographic examination, therfore pulp extirpation and calcium hydroxide($Vitapex^{TM}$) canal filling were carried out. After 16 months, root canal was filled with gutta-percha, and bleaching treatment was done. Treatment results were satisfactory both esthetically and functionally for 8 years and 5 months.

본 연구는 건축고도제한에 의해 생태학적 조경설계는 어떻게 통제되며, 또한 생태학적 조경 설계가 무엇인가를 구명하는 것이다. 따라서 두 가지 다른 단지를 비교하여 건축물 스카이라인이 주변경관과 조화로운 심미적 설계를 가능하게 하는 영향에 관하여 고찰할 수 있다. 이 비교를 통하여 스카이라인 통제가 아파트단지 계획과 설계에서 생태학적 조경설계에 영향을 주는가를 검증하게 될 것이며, 스카이라인이 통제된 아파트단지가 조경시설 설계에 있어서 전체적, 역동적, 반응적, 직관적 접근을 할 때 상대적으로 우선성을 표출할 수 있을 것이다. 아파트단지 계획·설계에 있어 건물고도제한이 적절하게 검토되어 스카이라인의 통제를 더 강하게 할수록 아파트단지에서 만들어진 조경환경의 특성이 강조되고 강화한 경관이 더 조화롭게 된다는 점에서 경관에 유용하고 편익이 있다. 생태학적 조경설계의 평가사항은 자기 지속적, 자연적·문화적 정체성, 개연적 외관, 생태학적 접근으로 이뤄진다는 전제 아래 세부사항 18개 항목을 표출하였다. 또한 스카이라인 통제는 자연적 경관을 보전하고 수목이 단지의 안팎으로 자연스럽게 펼쳐지는 녹지 네트워크와 야생 동물 코리도를 획득하기 위하여 독특한 경관을 설계하고 개성적인 것으로 도출하여 조화로운 심미성을 이룩하는데 유용하다는 것을 계량적으로 표출하였다. 아파트단지의 경관에서 의미 있는 것은 다양한 접근으로 설계되고 건물 스카이라인 통제방법을 강화함으로써 관리되는 스카이라인의 실루엣이 다양하고 개성적 형태를 표출한다는 것을 보여준다. 결과적으로 스카이라인의 영향과 생태학적 조경설계가 계량적 요소에 의해 상대적으로 비교될 수 있으며, 생태학적 조경설계의 평가시설지표는 보다 세분화됨으로써 전체적인 설계요소의 강도에 영향을 줄 수 있다.

반응성 첨가제로 사용된 HQ-PGE가 DGEBA/MDA계의 기계적 성질에 미치는 영향을 살펴보기 위해서 충격강도와 인장강도를 측정하였다. HQ-PGE의 함량이 25phr일 때 충격 강도는 첨가되지 않았을 때보다 40% 증가하고, 인장강도도 약간 증가하였다. 이것은 HQ-PGE가 합성될 때 생성된 수산기가 자촉매 반응을 하면서 에폭시 수지의 미반응된 에폭시기와 반응한 결과로 사료된다. Young's modulus와 신장율은 HQ-PGE의 함량이 증가함에 따라 크게 변화하지 않았다.

This study was conducted to investigate the effects of servicescape factors(space, convenience, aesthetics, comfortableness, cleanliness), brand reputation and experiences factors(feel, think, act, relate) on emotional and cognitive reactions of visitors to Korean restaurants. It also investigated the relationship between emotional and cognitive reactions and brand loyalty. A total of 353 questionnaires were analyzed using the factor analysis, a reliability test, and structural equation modeling analysis. The results revealed that space, aesthetics and comfortableness were positively related to emotional reaction, and convenience and cleanliness were related to cognitive reaction. This study also found that brand reputation was positively related to emotional and cognitive reactions. Moreover, it was found that think was positively related to emotional reaction, and feel, think, act and relate were positively related to cognitive reaction. Finally, cognitive reaction was positively related to loyalty. Therefore, Korean restaurant marketers should introduce or strengthen servicescape, brand reputation and experiences, which increases brand attitude or loyalty.

Corrosion is a complex series of oxidation/reduction reactions between at the water-metal surfaces and materials in which the water is stored or transported. With respect to the corrosion potential of drinking water, the primary concerns include the potential presence of toxic metals, such as lead and copper; deterioration and damage to the household plumbing, and aesthetic problems such as stained laundry, and bitter taste. This study was performed to evaluate the effects of corrosion inhibitors on corrosion rates, Fe and Cu release concentration in water distribution pipes. Decrease of corrosion rates were strongly related to phosphate corrosion inhibitors. Considering that typical corrosion processes consists of a series of electrochemical reaction at the metal surface in contact with water, corrosion rates were positively correlated with Fe release.

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.

In this study, the basic purpose was to identify the characteristics of the perception response of the elements that have an influence on the information search process for an assessment of product preference. Also, the relationship between the characteristics and the preference of products were reviewed in terms of the experience of the use of products. For this, photos of mobile phones and proposal-type products were selected and the experimental stimulant and experiments were conducted in two steps. In the first experiment, observations were made on the photos of the proposed products and they were arranged in the order of preference. In the second experiment, the part with the first attention in the preference assessment was marked by using the product photos that were previously selected and ranking them from 1 to 10. Two conclusions were obtained from the results of the experiment. First, the experimental memory information with the experience of the use of the products activates an interpretational response to the various constitutional elements included in the object for conception in the process of a preference rating. Second, no product use experience induces the reaction that perceptually accepts the esthetical elements included in the object for perception, regardless of preference.
