피부과 시술 후 피부 상태는 정상인과는 다른 피부 상태로 변화하게 된다. 시술과정에서 레이저와 같은 빛이 피부를 통과함에 따라 피부 홍반과 관계되는 화학적인 인자들이 활성화될 것이다. 이로 인해 피부에 건조함, 가려움, 벗겨짐 등이 발생할 수 있다. 비비크림의 본래의 목적은 메이크업 제품이라기보다는 민감한 피부에 스킨케어 기능을 제공해주는 제품이다. 일반적으로 사용되는 비비크림은 모든 피부 타입에 적합하며 특히 민감하고 여드름이 발생하기 쉬운 피부를 가진 사람들을 타깃으로 하고 있다. 그것은 피부상태를 개선해주는 스킨케어의 기능과 홍반이나 결점들을 효과적으로 커버해주는 메이크업 기능을 동시에 구현해주는 장점을 가지고 있다. 본 연구는 민감한 피부를 효과적으로 진정 및 홍반 개선을 해주는 스킨케어 기능과 홍반을 컬러적인 측면에서 자연스럽게 커버해주는 메이크업 기능을 갖는 제품에 대한 연구를 통해 피부과 시술 후 진정 및 홍반 개선 효과를 갖는 메이크업 제품을 개발하였다.

Mathematics is the subject which is distinctive in logical hierarchy, so the dificiency of prior learning or lack of understanding can result in learning disabilities of follow-up study. To minimize the learning disabilities, we should percieve student's problems and correct them through "Error Analysis" so that they can make up meaningful learning. Especially, in the case of division, its meaning is various, and the interpretation of the quotient and the remainder is the difference according to the caculation results, so students are likely to make errors often. Therefore, in this study, I presented the measures of how to instruct them under the circumstances in which division is applied by analyzing examples of incorrect answers.

Fingerprint Recognition System is made up of Off-line treatment and On-line treatment; the one is registering all the information of there trieving features which are retrieved in the digitalized fingerprint getting out of the analog fingerprint through the fingerprint acquisition device and the other is the treatment making the decision whether the users are approved to be accessed to the system or not with matching them with the fingerprint features which are retrieved and database from the input fingerprint when the users are approaching the system to use. In matching between On-line and Off-line treatment, the most important thing is which features we are going to use as the standard. Therefore, we have been using "Delta" and "Core" as this standard until now, but there might have been some deficits not to exist in every person when we set them up as the standards. In order to handle the users who do not have those features, we are still using the matching method which enables us to make up of the spanning tree or the triangulation with the relations of the spanned feature. However, there are some overheads of the time on these methods and it is not sure whether they make the correct matching or not. In this paper, introduces a new data structure, called Union and Division, representing binary fingerprint image. Minutiae detecting procedure using Union and Division takes, on the average, 32% of the consuming time taken by a minutiae detecting procedure without using Union and Division.

The aim of the research is to figure out how the perception and the attitude of hospital staff have effect on cost management behavior, to check the mediation effect in the relationship between cost attitude and cost management behavior, and to provide some basic data of efficient cost management means for hospital staff. The major results of research can be summed up as following. Subordinate factors of cost perception such as conviction, information, and thought were all revealed as meaningful effect ones on cost attitude, but they didn't have meaningful effect on cost management behavior. However, if we check the final results of direct effect, indirect effect, and total effect in its variants, we can understand that cost perception have indirect effect on cost management behavior via cost attitude. Cost attitude was revealed as the greatest variant having direct effect on cost management behavior. As a conclusion, it seems that the correct cost perception can make positive cost attitude, by which desirable cost management behavior can be induced. Therefore, as the correct cost perception can make positive attitude, it is necessary to construct effective system to provide useful cost information for staff at anytime and at any place continually on organization aspect. It is important to get correct cost perception for the positive attitude of staff. Nevertheless, if the positive attitude would not be formed, it is necessary to search for the ways for personal motivation, for the management behavior cannot emerge positively.

Purpose: Diplopia and cosmetically unacceptable enophthalmos are the major complications of blow out fracture. Prolapse of orbital tissue into the sinuses, enlarged orbital volume, atrophy of orbital fat and loss of support of orbital walls play a role in the pathogenesis of enophthalmos. To correct post-traumatic enophthalmos, freeing of incarcerated orbital contents combined with reduction of bony orbital volume and reconstruction of suspensory support of globe is necessary. But remained enophthalmos after surgical treatment is difficult to correct completely. In this case, the authors performed implant insertion for affected orbit and endoscopic orbital decompression for unaffected orbit for correction of late enophthalmos. Method: We reviewed a girl patient with right inferomedial orbital wall blow out fracture, right zygoma fracture treated at our hospital for correction of enophthalmos. An 18-year-old female had sustained posttraumatic enopthalmos. Two surgical management was performed for correction blow out fracture at the other hospital. But residual diplopia, enophthalmos, cheek drooping were found. And then she transferred to our hospital. She had severe enophthalmos(5 mm) also had diplopia and extraocular muscle limitation. We performed operation for correction of enophthalmos. After operation, she showed minimal improvement of diplopia and enophthalmos(3 mm). The authors make plan for operation for correction enophthalmos due to cosmetical improvement. Implant insertion was performed for affected orbit. For unaffected orbit, nasoendoscopic medial orbital wall decompression was proceeded. Result: Correction of enophthalmos was found after operation and was maintained for nine years follow-up. Patient expressed satisfaction for the result. Conclusion: To correct persistant enophthalmos, we could have satisfactory result with orbital wall reconstruction on affected eye and decompression on unaffected eye.

지문 인식 시스템은 지문인식 장치(fingerprint acquisition device)를 통하여 아날로그(analog) 지문으로 부터 변환된 디지털(digital) 지문에서 특이점을 추출하고 추출한 특이점들에 대한 정보를 데이터 베이스에 등록하는 오프라인(off-line) 처리와 사용자가 시스템에 접근 할 때 입력한 지문으로부터 특이점을 추출한 후 데이터베이스에 저장되어 있는 특이점들과 정합(matching) 하여 사용자의 시스템 접근 여부를 결정하는 온라인(on-line) 처리로 이루어져 있다. 정합에 있어서 가장 중요한 것은 어떤 기준점을 어떻게 설정하느냐 하는 것이다. 지금까지 삼각주나 코어를 기준점으로 잡거나, 기준점으로 설정하는 경우에는 모든 사람에게 존재하지 않는 단점이 있다. 특징점이 없는 사용자들을 처리하기 위하여 특이점들의 상호 관계를 스패닝 트리를 구성하거나, 삼각화를 하여 정합 하는 방법들이 이용되고 있다. 그러나 이러한 방법들은 시간에 대한 오버헤드가 있고 정확하게 정합 한다는 보장을 하지 못한다. 본 논문에서는 동일 등선 줄기 상에 있는 두 특이점을 잇는 선분을 기준점으로 선택함으로서 기존 정합 알고리즘과 비교하여 인식률이 높고 오인식률이 낮으며 효율성 면에서도 우수하고 정확하게 정합 하는 알고리즘을 제안한다.
