  • 현재 골 유착성 임플랜트는 안전하고 유용한 보철 수복 분야의 하나로 자리잡아 가고있다. 과거 완전 무치악 환자에게 있어서 저작 기능의 회복이란 면에 중점을 두었던 경향에서 현재 골유착 임플랜트의 높은 성공률에 의해 부문 무치악, 단일치 수복에 까지 다양하게 사용되고 있다. 특히 심미성과 인접치의 손상을 가하지 않는다는 면에서 단일치 수복에서 골유착 임플랜트 치료에 관심이 모아지고 있다. 단일치 수복에 있어서 심미성이 중요한 문제로 대두되면서 이런 수복에 사용될 수 있는 다양한 계통의 임플랜트들이 개발되어 사용되고 있다. 이중 가장 기본적인 Branemark 계통의 CeraOne 지대주, 최근에 개발된 전부도재 지대주인 CerAdapt 전부주조 지대주인 UCLA 계통등은 높은 성공률을 보이며 많이 사용되고 있다. 임상가들에 의해 나사유지형 보철물이 착탈성이란 관점에서 선호되고 있다. 시멘트유지형 보철물에서는 나사공이 없는 온전한 교합면을 유지한다는 면과 교합력을 받는 면적에 있어서 더 넓은 면을 가진다는 점등 더 많은 장점을 가진다고 주장하는 사람도 있다. 임상가들의 기호에 의해 선택되어지는 나사 유지형과 시멘트 유지형에 있어서 교합력이 야기하는 하중하에서 각각의 응력 분포를 분석할 필요성이 요구되었다. 이 연구는 단일치 수복에 사용되는 CeraOne, CerAdapt UCLA 계통에서 각각의 나사 유지형과 시멘트유지형에서의 응력분포를 삼차원 유한요소법으로 분석하고 상부 구조물에 가해지는 수직하중, 수평 하중, 경사 하중에 의해 야기되는 응력을 비교 분석한 것이다. 본 연구의 연구 결과는 다음과 같다. 1. CeraOne, CerAdapt, UCLA 지대주 모두 시멘트유지형보다 나사유지형에서 응력집중이 컸다. 2. CeraOne 시멘트유지형인 1번 모델에서 응력분산이 유리하였고, UCLA 나사 유지형인 6번 모델에서 가장 불리하였다. 3. 모든 모델에서 고정체 경부에서 가장 큰 응력 집중이 있었고 이것은 UCLA 지대주에서 가장 컸다. 4. 상부 구조물에서 주된 응력의 집중은 교합면에서 일어났다. 5. 골은 상부 피질골, 즉 고정체경부와 만나는 부위에서 가장 큰 응력의 집중이 일어났으며 수평, 경사 하중시 응력집중 양상은 힘을 가한 쪽의 반대쪽 고정체 경부에 응력이 집중되는 양상을 보였다. 6. 전체 모델과 골, 고정체 모두에서 수평 하중과 경사 하중시 보다는 수직 하중시 더 적은 응력값을 보였다.

  • The purpose of this study is to qualitatively examine the nature of the stress experience of nurses in reemployment after career interruption using a phenomenological method. The subjects were nurses who were reemployed after working in medical institutions and experiencing three years or more of career interruption. The collected data showed five categories of themes: "the gaps between reality and earlier expectations," "getting hurt because of the worsening relationship with younger superiors," "struggling to adapt oneself to the changing work environments," "getting exhausted as a supermom," and "struggling to survive as a professional." The findings suggest that career-interrupted nurses who are considering finding a new job should be educated to make decisions on where to work. They should be provided with the right information on the environments of hospitals and with educational programs before reemployment to establish their roles as professional nurses. In addition, it is important to increase the diversity and accessibility of retraining programs that can adapt to the changing healthcare environment. It is necessary to develop career break programs so that nurses can successfully adapt to reemployment, to promote professionalism in the work environment, and to look for ways that can inspire nurses who have experienced career interruption.

  • This study aimed to investigate the difference of the body orientation ability in sitting position to adapt to dynamically changing angle of the base of support in stroke patients and Healthy adults. The angle between vertical and head and trunk in 12 stroke patients (6 male and 6 female) and 12 healthy adults (6 male and 6 female) were measured by video motion analysis system. The head and trunk angle between stroke patients and healthy adults in sitting position were significantly different when increase the angle of dominant side(p<.05). The head and trunk angle between stroke patients and healthy adults in sitting position were significantly different when increase the angle of non-dominant side(p<.05). The head and trunk angle between stroke patients and healthy adults in sitting position were significantly different when decrease the angle of non-dominant side(p<.05). The head angle between stroke patients and healthy adults in sitting position was significantly different(p<.05), but the trunk angle was not significantly different when decrease the angle of dominant side(p>.05), Stroke patients compared to healthy adults had more deficits in their body orientation ability in sitting position to adapt to dynamically changing angle of the base of support. This finding may help to understand postural control deficits more clearly in stroke patients in sitting position.

  • The purpose of this research is to examine the effects of family social capital and community social capital on how successfully children adapt to school. Utilizing the second year data from the 1st year of middle school panel found in the 2010 Korea Children and Youth Panel Survey, descriptive statistical analysis, correlation analysis, and hierarchical linear model analysis were conducted successively on 2,056 second-year middle school students living in 93 communities. The data produced was used to determine what degree of influence family social capital and community social capital exert on the ability of children to successfully adapt to school. First, 6.1% of the variables relating to school adaptation were explained by differences among communities, and the remaining 93.3% were explained by differences among individuals. Second, the examination of the effects of family social capital showed that students who experienced lower rates of neglect also experienced less abuse, had parents who were more interested in and better informed about their lives, and better adapted to school. Third, the examination of the effects of community social capital showed that the higher the community spirit the communities had, the better the young students in the communities adapted to school. Fourth, when the effects of family social capital and community social capital were examined in conjunction with each other, it was found that the less neglect the students experienced, the less abuse the students experienced, the greater the interest their parents had in their close friends, the better they themselves adapted to school. In relation to community social capital, the level of community spirit was still found to exert positive effects on the ability of young students to successfully adapt to school.

  • De notre temps, nous faisons face ${\grave{a}}$ un changement du $th{\hat{e}}atre$ dans son ensemble. Le $th{\acute{e}}atre$ contemporain tente de se $d{\acute{e}}marquer$ des autres formes artistiques, mais aussi des formes $litt{\acute{e}}raires$, lorsque la tendance est ${\grave{a}}$ la fusion des genres. Il existe ainsi de plus en plus de $th{\hat{e}}atre$ ${e}xp{\acute{e}}rimentaux$, $n{\acute{e}}s$ sous le nom de $th{\acute{e}}atre$ anthropologique, $th{\acute{e}}atre$ sociologique, $th{\acute{e}}atre$ ethnologique, $th{\acute{e}}atre$ ${\acute{e}}pist{\acute{e}}miologique$ ou $th{\acute{e}}{\hat{a}}tre$ interculturel. La $m{\acute{e}}thodologie$ doit elle s'adapter ${\grave{a}}$ cette tendance de fusion? Au lieu de trouver une $m{\acute{e}}thode$ d'anlyse de chaque "nouveaux genre" $n{\acute{e}}$ de la fusion, nous nous interrogeons sur la $m{\acute{e}}thodologie$ pour ${\acute{e}}tudier$ le $th{\hat{e}}atre$ dans son ensemble. Si une telle $m{\acute{e}}thodologie$ d'analyse existait, quelle serait la $diff{\acute{e}}rence$ avec la $m{\acute{e}}thodologie$ $d{\acute{e}}j{\grave{a}}$ existante? Et si elle n'existait pas, quelle serait la meilleure $m{\acute{e}}thodologie$ $adapt{\acute{e}}e$? Nous $consid{\acute{e}}rons$ la $m{\acute{e}}thode$ d'analyse de la didascalie comme nouvelle $m{\acute{e}}thodologie$ $adapt{\acute{e}}e$. En effet, la didascalie $conna{\hat{i}}t$ sans cesse des $m{\acute{e}}tamorphoses$ dans $l^{\prime}{\acute{e}}criture$. De nombreux $th{\acute{e}}oriciens$ ont $d{\acute{e}}velopp{\acute{e}}$ des $m{\acute{e}}thodes$ d'analyse afin de mieux comprendre les diverses formes de $th{\acute{e}}atre$ comtemporain et ses didascalies. Notre travail est de rassembler les ${\acute{e}}tudes$ des $diff{\acute{e}}rents$ $th{\acute{e}}oriciens$ et de les ordonner ; afin de proposer un outil d'analyse $adapt{\acute{e}}$ pour $l^{\prime}interpr{\acute{e}}tation$ des $pi{\grave{e}}ces$ du $th{\acute{e}}{\hat{a}}tre$ contemporain.

  • This paper presents the algorithm for estimating the attitude of an underwater vehicle using EFK. The system model is designed by linerizing the nonlinear Euler angle differential equation and the measurements is a speed logger output. The simulation result shows that the estimation lagorithm is adequate for decreasing attitude errors that grow abruptly during the motion with acceleration and rotation. It also shows that we can adapt the algorithm for compensating initial attitude errors generated after initial leveling.

  • HVS based transform coding techniques for still images take the lowest spatial frequency and luminance contrast sensitivity as the most crucial factors in determining the image quality perceived by human eye. Only the frequency weighting has been main issue. The proposed Weighted Discrete Cosine Transform (WDCT) has the lowest frequency of about 4 [cyc/deg] in 8$\times$8 subblock with the contrast-weighted DC coefficient. The error criteria have been rederived to adapt the contrast weighting for performance evaluation. The proposed scheme has produced higher quality images compared to the unweighted and other schemes.
